Description

  The present invention provides a conductive stretch knitted fabric that has abundant stretchability and flexibility, has a resilience when repeated stretching, and has no or no change in electrical resistance even after repeated stretch. The present invention relates to a human body motion detection wear as an example to which the conductive harness used is preferably applied.

Conventionally, a sheet that has been knitted or woven by alternately arranging conductive parts and non-conductive parts has been proposed (Patent Document 1). In this sheet, one of the options is to knitting or weaving the conductive portion using a metal thread such as gold, silver, or copper. Further, it has been assumed that conductive yarn is used for warp during weaving.
On the other hand, there has been proposed a fabric in which stretchable transmission lines configured to suppress disconnection and damage to the base fabric even when the fabric is repeatedly stretched (Patent Document 2). In this fabric, for the stretchable transmission line, four aggregated wires bundled with 100 copper wires having a diameter of 0.03 mm are twisted around a braid having a diameter of 1.8 mm, and false twisted yarn is further doubled around the braided yarn ( Only those constructed by twisting two layers) are illustrated.

  Biological information is acquired by the sheet disclosed in Patent Document 1 described above, or the telescopic transmission line disclosed in Patent Document 2 is applied to a motion capture system that detects the motion and posture of a human body. As a technique for detecting such movements and postures of the human body, a motion capture device for fingers using a magnetic position and orientation sensor for recording and reproducing delicate movements of fingers has been proposed (Patent Document 3). An apparatus that includes a plurality of sensor elements for providing an index related to the position of at least a part of the user's body and that can be worn by the user has been proposed (Patent Document 4).

  In the sheet of Patent Document 1, if metal parts such as gold, silver, copper, etc. are used for conductive parts, or if conductive threads are used for warp during weaving, the crease is strong and abundant in flexibility. Difficult to do. In addition, when the sheet is used for expanding and contracting, the metal thread repeatedly undergoes plastic deformation, which may increase the risk of disconnection. In addition, since the restoring property to elongation is low, the period of use in which stretchability is obtained is limited, and it has an unsuitable aspect as an application where stretchability is expected.

  On the other hand, in the fabric of Patent Document 2, it is presumed that the stretchable transmission line alone is equivalent to about 1 to 2 mm in terms of diameter even with only the copper assembly line. Furthermore, since a double (two-layer) coating layer made of false twisted yarn is required, the overall thickness is considerably large. Therefore, even if the disconnection due to expansion and contraction is suppressed, it must be said that there is no expectation in terms of abundant elasticity, abundant flexibility, resilience to elongation, and the like.

  As described above, whether it is the sheet of Patent Document 1 or the fabric of Patent Document 2, it is a knitted fabric that is rich in stretchability and flexibility and has resilience when it is repeatedly stretched. It can be said that no attention was paid to the provision of a property in which there is no or no change in electrical resistance between stretching. In addition, when wiring between multiple boards, the wiring path has a complicated bend due to the arrangement of each board, or the wiring length and wiring path have not been determined until the wiring stage. When the substrates move after wiring, for example, it is unsuitable to use the sheet of Patent Document 1 or the fabric of Patent Document 2 as a wiring member.

  Further, in Patent Document 2, as a method of arranging a wiring member (expandable transmission line) on a cloth (base cloth), (1) an elastic transmission line is attached to the base cloth by sewing, and (2) a cylinder attached to the base cloth The following three types are disclosed: an extension transmission line is provided inside the shaped member, and (3) the extension transmission line is inserted into a woven or knitted fabric structure constituting the base fabric. However, if the stretchable transmission line is repeatedly stretched when the stretchable transmission line is arranged on the fabric by such a method, disconnection of the stretchable transmission line, damage to the base fabric, or separation of the stretchable transmission line from the base fabric can be sufficiently suppressed. It cannot be said that sufficient durability cannot be realized. Furthermore, in any of Patent Document 1 and Patent Document 2, when a wiring member (expandable transmission line) is actually arranged on a fabric (base fabric) and used, the connection technique with an electronic device or the like and the wiring member (expandable) There is no problem, disclosure, or suggestion regarding a problem regarding a transmission line management technique.

  In Patent Document 3, when placing a magnetic position / orientation sensor on a finger, emphasis is placed on being able to be attached regardless of the size of the hand, and the glove that fixes the transmitter and the palm sensor has a stretchable surface fastener. The other sensor is disclosed only as a structure that is mounted by using a taping that is rich in elasticity. Further, in Patent Document 4, although a jacket including a sensor is shown, a method for realizing the jacket is a refined fabric in which a conductive fiber is knitted into the jacket, or a mesh or a net that can adhere to a user's skin. It is only disclosed that it is possible to use a probe in the shape of a ring. That is, in any of Patent Document 3 and Patent Document 4, a human body motion detection wear that a person wears by actually arranging a sensor and a controller together with a wiring member (expandable transmission line) on a fabric (base fabric). There is no disclosure, suggestion, or solution for problems in attaching the wiring member, sensor, and controller to the wear.

  The present invention has been made in view of the above circumstances and has abundant stretchability and flexibility, and also has resilience when repeated stretching, and there is no or no change in electrical resistance even after repeated stretching.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the conductive stretch knitted fabric 1 itself, the conductive harness structure and the conductive harness mounting structure are included in the objects according to the present invention.
FIG. 1 is a double-sided stitch diagram illustrating a first embodiment of a conductive stretchable knitted fabric 1 according to the present invention. The conductive stretch knitted fabric 1 can be used as one of its constituent elements when manufacturing a conductive harness 2 as shown in FIG.

The harness 2 shown in FIG. 2 is formed to have a flat and slender band shape, and includes two conductive parts parallel to each other along the longitudinal direction of the band. These two conductive portions are formed by the conductive stretchable knitted fabric 1 according to the present invention (hereinafter referred to as “the knitted fabric 1 of the present invention”).
In the example shown in FIG. 2, the knitted fabric 1 of the present invention is formed in a strip-like shape and exposed on the front and back surfaces of the harness 2, and the two knitted fabrics 1, 1 are mutually short-circuited. It is assumed that a non-conductive portion 3 is provided to prevent this.

  In addition, a non-conductive portion 4 is also provided outside the band width direction with respect to the knitted fabrics 1 and 1 of the present invention, and when the side edge of the harness 2 comes into contact with another object, Countermeasures are taken to prevent electrical leakage. The non-conductive portions 3 and 4 are all composed as a knitted fabric knitted only with non-conductive yarns such as synthetic fibers (for example, aramid fibers), natural fibers, and a mixture of synthetic fibers and elastic yarns. Like the knitted fabric 1 of the present invention, it is formed so as to be exposed on the front and back surfaces of the harness 2.

The knitted fabric 1 of the present invention may be provided with three or more in the band width direction of the harness 2 so that they are separated by the non-conductive portion 3, or one in the band width direction of the harness 2. You may provide only. Further, the non-conductive portion 4 may be provided only on one side of the knitted fabric 1 of the present invention or may not be provided.
In addition, the knitted fabric 1 of the present invention can be formed in a line shape instead of a band shape, or can be formed as a wide one that forms all of the band width direction and the band longitudinal direction of the harness 2 (these elements). Will be described later). In short, the arrangement and number of the knitted fabric 1 of the present invention are not limited at all. In addition, the harness 2 itself is not limited to being formed in the form of a strap, but can be formed in a square such as a square or a rectangle.

  In the harness 2 shown in FIG. 2, naturally, the knitted fabric 1 (two conductive portions) of the present invention has a conduction characteristic with low electrical resistance at both ends in the belt longitudinal direction. In addition, even at an arbitrary position in the longitudinal direction of the belt, the belt surface and / or the back surface of the belt has a conduction characteristic with low electrical resistance. Therefore, it may be used such that the magnitude of the electrical resistance is set according to the distance between the two points conducted in the longitudinal direction of the belt of the knitted fabric 1 of the present invention, or the length according to the electrical resistance is set on the contrary. . Alternatively, the magnitude of the electric resistance can also be set by selecting whether the width (number of courses) of the knitted fabric 1 of the present invention is wide or narrow.

  In addition, this harness 2 has abundant stretchability along the longitudinal direction of the belt, and the warp and bend in the front and back direction, with the knitted fabric 1 of the present invention and the non-conductive portions 3 and 4 integrated. It has abundant flexibility that can flexibly bend to the left and right along the surface direction, and even torsion. And when the harness 2 is expanded and contracted in the longitudinal direction of the belt in this way, bent or bent in the front and back direction, or bent along the surface direction, and further when these expansion and contraction, warping, and bending are repeated Even so, the electrical resistance has the characteristic of being held in an invariable state.

Here, “low electrical resistance” means that the voltage drop when a current flows is a resistance value that does not affect the function. Specific resistance values vary depending on the application and use conditions. For example, for power supply, it is preferably 10 Ω / m or less, more preferably 1 Ω / m or less, and further preferably 0.1 Ω / m or less. However, the allowable range varies depending on the wiring length and supply current.
In general, compared to power supply, signal current is generally low in current, so it can be tolerated to a higher resistance value. On the other hand, “stretchability” refers to non-extension (normal state) This is a characteristic that has both the extension of the image and the immediate restoration by releasing from the extended state. It can be appropriately changed whether the stretchability of the knitted fabric 1 of the present invention and the non-conductive portions 3 and 4 have the same strength or different strength. For example, each stretch may be set with the goal of preventing wrinkles and undulations from becoming noticeable as a whole knitted fabric, and suppressing stretchability so that the conductive yarn 10 is not damaged during stretching load. .

The degree of elongation (extension) from the non-stretched state is determined by the material and thickness of the material used for knitting (yarn), whether or not the knitting material is mixed, and how it is mixed (covering, plating, and assortment). Etc.), various factors such as the number of mixed use, the band width and band length of the harness 2, and the like can be dealt with by appropriately changing according to a desired place.
Needless to say, the degree of elongation can be appropriately changed by selecting the composition. In this case, especially when designing the knitting of the knitted fabric 1 of the present invention, adjustment of the loop length of the conductive yarn 10, the elastic modulus of the elastic yarn 11, and the draft (stretching the short fiber bundle to make it thin), which will be described later. Is a major factor.

  In terms of restoration, it is ideal to restore 100% to the length at the time of non-extension. However, 100% recovery is not necessarily limited. If the number of repetitions of extension and restoration is specified, and if it is within this specified number, it has a characteristic that recovers 80% or more. It is sufficient to set the performance according to the application. If this “stretch-restore repetition number” is less than 1000, it must be said that it is practically unsuitable for practical use.

  The “elongation-restoration repetition number” can be counted by a repeated tensile fatigue test using a dematcher type repeated fatigue tester. In this case, a rectangular specimen having a long side in the course direction is used as the test piece as the harness 2. In this embodiment, the dimension of the test piece is 10 cm long and 1.5 cm short. Also, in the test piece, 40th cotton yarn is used for each of the non-conductive portions 3 and 4 that are arranged so as to sandwich the both sides of the conductive portion (knitted fabric 1 of the present invention). Consideration was given not to give (disturbance).

  The test piece is marked at intervals of 5 cm when not stretched. The stroke (stretching degree) was adjusted with the marking interval being 10 cm when stretched. The test is performed at room temperature, and stretching and restoration are repeated 3000 times and 10,000 times at a rate of 60 times / minute, and then the marking interval and the resistance value between the markings are measured to obtain a prescribed result. By confirming that this is the case, it was considered that the number of repetitions was achieved.

  Such a harness 2 can be manufactured by adopting, for example, a method described in JP-A No. 11-279937 (a method of taking out a tape fabric from a tubular fabric). That is, when performing knitting of a cylindrical fabric using a circular knitting machine, the non-conductive portion 4 on the outer side in the band width direction, the knitted fabric 1 of the present invention, the non-conductive portion 3 in the center of the band width direction, the knitted fabric 1 of the present invention, Performs piece knitting to knive a total of 5 sections of the non-conductive part 4 on the outer side in the band width direction simultaneously from a plurality of yarn feeders, and inserts tether yarn that melts with heat, water, solvent, etc. between the pieces, This is a method in which the harness 2 is taken out while being spirally separated by performing a process of melting the joining yarn from the tubular fabric obtained after knitting.

When knitting the knitted fabric 1 of the present invention, the conductive yarn 10 and the elastic yarn 11 are mixedly used as shown in FIG. As long as the conductive yarn 10 and the elastic yarn 11 are included, it is optional to mix other types of yarn.
The knitting structure that can be employed in the knitted fabric 1 of the present invention is, for example, a smooth knitting (also referred to as double-sided knitting or interlock). The smooth knitting is a knitting structure in which two rubber knitting layers are overlapped to fill each other's uneven grooves. That is, when the upper surface side of FIG. 1A is set to the knitted fabric surface side and the lower surface side is set to the knitted fabric back surface side, the conductive yarn 10 is entangled with the conductive yarn old loop 10a on the knitted fabric surface side. One loop P1 is formed, and the process proceeds to the back side of the knitted fabric. Then, the second loop P2 is formed by being entangled with the conductive yarn old loop 10b on the back side of the knitted fabric, and thereafter the third loop P3 is similarly formed on the knitted fabric surface side, and the fourth loop P4 is formed on the back side of the knitted fabric. Repeat these things. Therefore, the conductive yarn 10 is provided in a zigzag arrangement in the front-back direction in the knitted fabric of the knitted fabric 1 of the present invention.

  On the other hand, the elastic yarn 11 is entangled with the elastic yarn old loop 11a on the back side of the knitted fabric to form a first loop R1, and moves to the knitted fabric surface side. Then, the second loop R2 is formed by being entangled with the elastic yarn old loop 11b on the knitted fabric surface side, and thereafter the third loop R3 is similarly formed on the back side of the knitted fabric, and the fourth loop R4 is formed on the knitted fabric surface side. Repeat that. Accordingly, the elastic yarn 11 is also provided in a zigzag arrangement in the front-back direction in the knitted fabric of the knitted fabric 1 of the present invention. As a result, in the knitted fabric, the cross portions 13 of the conductive yarns 10 and the elastic yarns 11 are formed alternately for each loop.

  However, while the elastic yarn 11 has abundant stretchability, the conductive yarn 10 hardly stretches. Therefore, when the knitted fabric 1 of the present invention is stretched along the surface direction of the front and back surfaces (the left-right direction in FIG. 1A and the same as the “course direction” described later), the cross section 13 has elastic yarns. The cross angle θ generated on the front and back sides of the knitted fabric by 11 intersecting with the conductive yarn 10 is gradually enlarged, and only the elastic yarn 11 gradually grows gradually through a situation where the angle becomes obtuse. .

Next, a behavior occurs in which the conductive yarn 10 is drawn out from the loop to the cross portion 13 by being pulled by the stretch of the elastic yarn 11.
Further, when the elongation of the knitted fabric 1 of the present invention is released, only the elastic yarn 11 generates a tightening force due to the contraction in the cross portion 13, and the conductive yarn 10 receives the tightening force from the cross portion 13 to the outer loops. Pushing behavior occurs. The tightening force of the elastic yarn 11 at this time has the effect of retaining the zigzag arrangement of the conductive yarn 10 and having the volume in the thickness direction in the knitted fabric 1 of the present invention when not stretched.

As described above, the conductive yarn 10 is not only expanded or pushed down from the loop to the cross portion 13 but also made smaller or larger, and the conductive yarn 10 is stretched or contracted together with the expansion and contraction of the elastic yarn 11. Thus, the knitted fabric 1 of the present invention has elasticity as shown in FIG.
As is apparent from this explanation, since the conductive yarn 10 does not substantially expand and contract, the total length used in the course direction does not change, and the outer diameter does not change. In addition, the conductive yarn 10 does not contact the loops arranged in the course direction, and does not get entangled or contact between the plurality of courses. Therefore, the electrical resistance is also unchanged.

  In the knitted fabric 1 of the present invention, it can be said that the same course in the knitted fabric is separated into a configuration path knitted by the conductive yarn 10 and a configuration path knitted by the elastic yarn 11. For this reason, the influence (interference) of the expansion / contraction behaviors in the mutual configuration paths is suppressed and becomes independent of each other. Therefore, the expansion / contraction behaviors having a high degree of freedom are allowed in the respective configuration paths. Thereby, as the knitted fabric 1 of the present invention, abundant stretchability and flexibility are ensured.

  In the knitted fabric configuration in which the configuration path of the conductive yarn 10 and the configuration path of the elastic yarn 11 are separated as described above, a large number of the conductive yarns 10 can be put in the configuration path of the conductive yarn 10. Therefore, the electric resistance value of the knitted fabric 1 of the present invention can be set as low as possible. Similarly, in the case of the elastic yarn 11, a large number of elastic yarns 11 can be put in one path. With regard to adding a large amount of elastic yarn 11, this leads to the advantage that the elastic characteristics can be improved.

As a method of obtaining a knitted fabric configuration in which the configuration path of the conductive yarn 10 and the configuration path of the elastic yarn 11 are separated, when the knitted fabric 1 of the present invention is knitted, the conductive yarn 10 and the elastic yarn 11 are different knitting points. The method of knitting and forming a separate loop can be presented.
The “course direction” is a direction in which a loop connected in the knitting structure is formed, and is the same direction as the “course”. The direction perpendicular to the course direction on the knitted fabric ground is set to “Wale” or “Wale direction”. “Between courses” is between courses adjacent to each other in the wale direction.

  From this, in the knitted fabric 1 of the present invention, it is clear that the conductivity in the course direction is expressed by one course of the conductive yarn 10 (as one continuous conductive yarn 10). In order to reduce the electrical resistance value of one course, the conductive yarn 10 used in one course is increased in the number of conductive yarns 10 by S twist, Z twist, alignment, plating, etc., or low electrical resistance. You can choose the material or make it thicker.

  Further, in order to make the elasticity more abundant, there is a method in which a thick polyurethane yarn and a high elastic modulus polyurethane yarn having a strong restoring force (kickback) against elongation are used with a high draft (short loop length). Further, a relatively thin elastic yarn 11 (polyurethane or the like) is supplementarily supplied to the path of the conductive yarn 10, or a covering yarn (elastic yarn 11 such as polyurethane is used for the “core” and the conductive yarn 10 is used for the “cover”. There is also a method such as using a method using However, these methods only serve as an auxiliary role for the stretching behavior.

  The conductive yarn 10 is made of, for example, pure metal such as aluminum, nickel, copper, titanium, magnesium, tin, zinc, iron, silver, gold, platinum, vanadium, molybdenum, tungsten, cobalt, alloys thereof, stainless steel, brass, etc. The formed metal wire can be used. In some cases, carbon fibers can be used instead of metal wires. The wire diameter is preferably 10 to 200 μm. In particular, it is desirable to use a bundle of small diameter fibers. As described above, the metal wire is not particularly limited as to whether it is easily plastically deformed or whether it has a significant elastic restoring force (spring property).

  In addition, the conductive yarn 10 may be made of a resin fiber (nylon, polyester, polyurethane, fluororesin, or the like) covered. By doing so, the knitted fabric 1 of the present invention can be provided with functions such as hydrophilicity, water repellency, corrosion resistance / corrosion resistance, and coloring. Further, the conductive yarn 10 can be subjected to a surface treatment by wet or dry coating or plating on resin fibers or metal wires, or an organic or inorganic thin film can be formed by vacuum film formation. is there.

Furthermore, the conductive yarn 10 can be formed into a composite yarn by elastic yarn 11 and twisting, covering processing, or drawing.
The elastic yarn 11 may be a polyurethane or rubber-based elastomer material, or a covering yarn using polyurethane or elastomer material for the “core” and nylon or polyester for the “cover”.

  Note that it is recommended that the elastic yarn 11 be selected of a material so that the elastic yarn 11 does not extend beyond the elongation that is the limit of the tensile strength of the conductive yarn 10 (for the purpose of limiting the elongation of the conductive yarn 10). When a covering yarn is employed as the elastic yarn 11, it is possible to select a material so that the “cover” has a function of limiting the elongation of the conductive yarn 10. Further, the selection of the material for the elastic yarn 11 itself or “cover” may be performed for the purpose of adapting to the expansion and contraction behavior required for the knitted fabric 1 of the present invention. Further, for the purpose of limiting the elongation (load) of the conductive yarn 10, it may be controlled by the non-conductive portions 3 and 4.

For example, if the restoration (return) from elongation is required to be steep and strong, the elastic yarn 11 that is relatively thick and highly elastic is selected. On the other hand, if it is required that the restoration from the extension be performed slowly and slowly, the elastic yarn 11 having a relatively thin and weak elasticity is selected.
As is apparent from the above description, the knitted fabric 1 of the present invention is a knitted fabric that is rich in stretchability and flexibility and also has a resilience when it is repeatedly stretched. And has the characteristic that no change in electrical resistance is present or suppressed. For this reason, in the case of wiring between a plurality of substrates, the wiring route has a complicated curve due to the arrangement of each substrate, or the wiring length and wiring route are not determined until the wiring stage. As a suitable wiring member when the boards move after wiring, or when large expansion and contraction fluctuations occur repeatedly in the wiring distance due to the movement of the moving body under the situation of wiring between the board and the moving body, etc. It can be used.

Further, since the electric resistance is unchanged between the extension time and the non-extension time, it can be suitably used as a signal line that dislikes disturbance.
The knitted fabric 1 of the present invention causes the conductive yarn 10 to behave between the stretched state and the non-stretched state of the knitted fabric by being accompanied by a tightening force (shrinking force) in the surface direction by the elastic yarn 11. Therefore, in the knitted fabric 1 of the present invention, one of the characteristic points is that a metal wire can be used as the conductive yarn 10 while exhibiting abundant stretchability (for example, 200% or more).

  In this way, when a metal wire is used for the conductive yarn 10, the electric resistance can be suppressed much lower than that of the plating yarn, and the energized voltage value and current value can be increased without increasing the thickness of the knitted fabric. Also suitable (can be thin). Moreover, there exists an advantage that durability as a conductive part and by extension, the knitted fabric 1 of this invention can be improved. Furthermore, the design can be improved and the development in appearance can be expanded widely.

  FIG. 3 is an organization chart showing a second embodiment of the conductive stretch knitted fabric according to the present invention. In the second embodiment, cardboard knit is adopted for the knitting structure. The corrugated cardboard knit is a knitted structure in which plain knitting is overlapped on the front and back sides and bonded between them by a tack (arrow T). That is, when the upper surface side of FIG. 3 is set to the knitted fabric surface side and the lower surface side is set to the knitted fabric back surface side, the conductive yarn 10 is tucked with the flat knitted loop 20a on the knitted fabric surface side to be knitted fabric back surface side. The knitted fabric of the knitted fabric 1 of the present invention is provided in a zigzag arrangement in the front-to-back direction by repeating the tucking with the flat knitted loop 20b on the back side of the knitted fabric.

  On the other hand, the elastic yarn 11 is knitting a flat knitting on the knitted fabric front side and the knitted fabric back side. Therefore, the tightening force (shrinkage force) along the surface direction of the front and back surfaces of the elastic yarn 11 causes the zigzag arrangement of the conductive yarn 10 in the knitted fabric 1 of the present invention when not stretched to maintain the thickness. The effect is to have a directional volume. Other configurations and operational effects are substantially the same as those in the first embodiment.

FIG. 4 is an organization chart showing a third embodiment of the conductive stretch knitted fabric according to the present invention. The third embodiment also has a knitting structure in which a flat knitting is overlapped on the front and back and bonded to each other, and the conductive yarn 10 is between the knitted fabric surface side and the knitted fabric back side. They are arranged in a zigzag shape in the inter-direction.
The difference from the second embodiment is that the conductive yarn 10 is formed in a zigzag manner in the front-to-back direction of the knitted fabric, and the elastic yarn 11 is formed so as to generate a tightening force along the surface direction of the knitted fabric. The conductive yarn 10 and the elastic yarn 11 are movably connected to each other (the state in which the expansion and contraction operation is freely allowed) and are held on the contraction side. FIG. 4 shows a cross-sectional structure of the knitted fabric. Actually, the loop 21 of the conductive yarn 10 and the loop 20 of the elastic yarn 11 are respectively ridges connected in a hook shape on the front and back surfaces of the knitted fabric. Is forming. Therefore, it does not happen that one of the loops slips out toward the thickness center of the knitted fabric (explained that each other's path is “tangled”).

Other configurations and operational effects are substantially the same as those in the first embodiment.
[Example]
Examples of the knitted fabric 1 of the present invention will be illustrated below, but these are disclosed for assisting technical understanding, and the technical scope of the present invention is not limited to the following examples.
Example 1
Using four copper wires with a wire diameter of 50 μm as the conductive yarn 10 and 235 dt polyurethane as the elastic yarn 11, knitting was performed smoothly (see FIG. 1).
(Example 2)
Using one nickel wire with a wire diameter of 40 μm as the conductive yarn 10 and 235 dt polyurethane as the elastic yarn 11, the yarn was knitted smoothly (see FIG. 1). Since nickel wire has good weather resistance, it can be said that it is particularly suitable when used in a part where the environment is important.
(Example 3)
As the conductive yarn 10, a composite yarn composed of three copper wires having a wire diameter of 50 μm and 110 dt polyurethane was used, and 235 dt polyurethane was used for the elastic yarn 11, and knitting was performed smoothly (see FIG. 1).
Example 4
Using three copper wires with a wire diameter of 50 μm as the conductive yarn 10 and 235 dt of polyurethane as the elastic yarn 11, knitting was performed by cardboard knit (see FIG. 3).
(Example 5)
Inlay was performed using three copper wires having a wire diameter of 50 μm as the conductive yarn 10 and 235 dt polyurethane as the elastic yarn 11, and knitting was performed using a milling inlay (see FIG. 6).
(Example 6)
A plating knitting made of three copper wires having a wire diameter of 50 μm and 110 dt polyurethane was used as the conductive yarn 10 and knitted by a milling cutter (rubber knitting). Since the knitting structure by the milling cutter has sufficient volume of the knitted fabric, it can be expected to act as the elastic yarn 11 on the polyurethane inserted by the plating knitting.
(Comparative example)
A plating knitting made of three copper wires having a wire diameter of 50 μm and a polyurethane of 110 dt was used as the conductive yarn 10 and knitted by a single (flat knitting). Since the single knitted structure has insufficient volume as the knitted fabric thickness, it cannot be expected that the polyurethane inserted by the plating knitting functions as the elastic yarn 11. That is, it can be said that this comparative example does not employ the elastic yarn 11.

  As shown in Table 1, in Examples 1 to 5, the maximum elongation of 250 to 300% can be realized, and even if the expansion and contraction is repeated 10,000 times with respect to this maximum elongation, it can only withstand practical use. It was confirmed that strong resilience was maintained. In the milling machine (rubber knitting) employed in Example 6, the conductive yarn 10 in the knitted fabric has a volume in the direction between the front and back, and has the same configuration as the zigzag arrangement. The durability of 3000 times can be achieved as “the number of repetitive restorations”. In this sense, the effect of the present invention can be obtained.

On the other hand, in the comparative example, since a single (flat knitting) is adopted, the conductive yarn 10 in the knitted fabric is not arranged in a zigzag shape in the front-back direction, and the elastic yarn 11 is not adopted. Since it was equal, the maximum elongation was small and the restoring force was poor.
In the case where the expansion / contraction operation is repeated, it is preferable that the amplitude is set to about ½ of the maximum elongation in consideration of the influence on the conductive yarn 10. Therefore, it can be said that the maximum elongation shown in Table 1 is preferably one that provides a large numerical value, although it depends on the amplitude setting.

On the other hand, using the knitted fabric 1 of the present invention having a smooth structure (see FIG. 1) for the conductive part, a harness 2 according to the present invention (having the configuration shown in FIG. 2) was manufactured as follows.
The non-conductive portion 3 in the center in the width direction and the non-conductive portion 4 outside in the width direction have the same number of courses and materials used. In addition, two courses each were provided so as to border both side edges in the width direction of the band to improve handling.

  Further, the conductive path (the knitted fabric 1 of the present invention) is provided with a configuration path employing enameled wire as the conductive yarn 10, and the non-conductive section 4 is configured with aramid fiber as the non-conductive yarn. Was provided.

  Since the enameled wire used as the conductive yarn 10 of the conductive portion (the knitted fabric 1 of the present invention) is resin-coated, it has a characteristic that insulation from the surroundings is ensured. Moreover, since the aramid fiber used for the non-conductive portions 3 and 4 has excellent heat resistance, it can withstand the heat of soldering when performing electrical wiring. Therefore, the problem that the nonconductive portions 3 and 4 are melted by the soldering heat occurs, and the resin coating of the enameled wire of the conductive yarn 10 is skillfully melted so that the soldering can be surely and easily performed.

By the way, the present invention is not limited to the above-described embodiments, and can be appropriately changed according to the embodiments.
For example, the knitted fabric 1 of the present invention is not limited to knitting as a cylindrical fabric, and may be knitted as a non-cylindrical sheet. Therefore, knitting can be performed by a general-purpose knitting machine such as a circular knitting machine or a flat knitting machine.

  The knitted fabric 1 of the present invention may be a smooth knitting described in FIG. 1, a corrugated cardboard knit described in FIG. 3, a knitting structure described in FIG. Knitting can be performed by the knitting structure. For example, eight locks as shown in FIG. 5 and milling inlays as shown in FIG. 6 and further illustrations, such as Milan Rib, Mock Milan Rib, one side, three steps, cord lane, deer Can do. Warp knitting can also be adopted.

The knitted fabric 1 of the present invention has many fields of use such as for clothing (as a wearable material) in addition to the above-mentioned power supply, signal, and medical use.
In the knitted fabric 1 of the present invention, it is necessary to provide at least two courses with the conductive yarns 10 adjacent in the wale direction, but there is no limitation on how much the number of courses is increased. Therefore, the knitted fabric 1 of the present invention can be formed in a linear shape or a wide band shape. Therefore, as the harness 2 as shown in FIG. 2, all of the band width direction and the band longitudinal direction can be formed as the knitted fabric 1 of the present invention.

The knitted fabric 1 of the present invention can also be formed as a quadrangle such as a square or a rectangle. In this case, for example, it can be employed as an electrode or the like for sensing and acquiring biological information.
In addition to the conductive yarn 10 and the elastic yarn 11, a knitting yarn for preventing elongation (preferably a non-elastic yarn, but a yarn whose elongation is restricted by twisting or knitting structure) may be mixed. It is. It is better to stop stretching by the knitting yarn and knitting design of the non-conductive portions 3 and 4.

In the case where the same course in the knitted fabric is separated into a constituent path knitted by the conductive yarn 10 and a constituent path knitted by the elastic yarn 11, a part or all of the conductive yarn 10 is non-conductive. It is possible to align other thread materials having the same properties or to align other conductive thread materials to a part or all of the elastic thread 11.
As described above, the conductive stretch knitted fabric 1 according to the present invention can be used as one of the components when manufacturing the conductive harness 2 as shown in FIG. 2 has many fields of use such as for power supply, for signal, for medical use, and for clothing (as wearable material). In the following, in this application field, when the conductive harness 2 is employed, an electronic device when the conductive harness 2 as a wiring member is actually arranged and used on a fabric (fabric, base fabric) is used. Connection technology (conducting harness), wiring member handling technology (conducting harness structure), and fabric mounting structure (conducting harness mounting structure) capable of realizing sufficient durability will be described in detail. .

  FIG. 7 is a view corresponding to FIG. 1 (a), and FIG. 7 (a) is a double-sided stitch diagram in the cross-sectional direction of the conductive harness according to the present invention using the conductive stretchable knitted fabric 1 shown in FIG. FIG. 7B is a double-sided stitch diagram in the cross-sectional direction of the conductive harness structure according to the present invention using the conductive stretchable knitted fabric 1 shown in FIG. 7, the same components as those in FIG. 1 are denoted by the same reference numerals, and not only their structures but also their functions are the same. Therefore, detailed description thereof will not be repeated here.

  As shown in FIG. 7 (a), the conductive harness according to the present invention has a small piece of metal (for example, metal pin 30) joined to the metal wire (conductive yarn 10) shown in FIG. 1 (a). It is characterized by being provided through the back surface. As shown in FIG. 7 (b), the conductive harness structure according to the present invention is formed by superposing at least two knitted fabrics shown in FIG. 1 (a) (in this case, as described later) One metal piece (for example, metal pin 30) whose longitudinal direction is shifted so as to be directed in a different direction is connected to the first conductive harness metal wire (conductive thread 10) and the first conductive harness metal wire ( It penetrates the surface of the first conductive harness and the back surface of the second conductive harness so as to be joined to the metal wire (conductive yarn 10) of the second conductive harness corresponding to the conductive yarn 10). It is characterized by being provided.

  In the conductive harness and the conductive harness structure according to the present invention, for example, as shown in FIG. 2, the conductive portion (conductive stretchable knitted fabric 1) is formed long in a band shape, and the nonconductive portion (Non-conductive part 3 and non-conductive part 4) form an insulating part along the strip-like longitudinal direction of the conductive part (conductive stretch knitted fabric 1), and the conductive part and the insulating part alternate in the strip-like short direction. Is formed. The metal piece is not particularly limited as long as it does not straddle adjacent conductive portions, but here, it will be described as a metal pin 30 having a pin shape.

Hereinafter, the conductive harness and the conductive harness structure according to the present invention will be described in detail.
The conductive wire shown in FIG. 7 (a) and the metal wire (conductive yarn 10) in the conductive harness structure shown in FIG. 7 (b) are formed of a metal strand covered with an insulating material having solder melting properties. In general, the conductive harness shown in FIG. 7 (a) and the conductive harness structure shown in FIG. 7 (b) are often small pieces (metal pins 30). ) And the metal element wire (both structurally (mechanically) and electrically) are joined. Note that this joining method is not particularly limited and may be joined by an adhesive or the like (other than by soldering), but in the following, a small metal piece (metal pin 30) and a metal wire (conductive thread 10). ) Is assumed to be joined by soldering. Moreover, although the raw material of a metal strand is not limited below, below, it demonstrates as a metal strand is a copper wire.

  Here, the insulating material (enamel conductor coating material) that forms the conductive yarn 10 by covering the copper wire which is a metal strand is not particularly limited as long as it has high-temperature meltability, In general, thermoplastic synthetic resins such as polyurethane, polyester, polyesterimide, and polyamideimide are preferable. Further, due to the high-temperature melting property of the insulating material (coating material), when the metal piece (metal pin 30) and the metal wire of the metal wire (conductive thread 10) are soldered, the melting temperature of the solder (approximately 170 ° C.). The insulating material (enameled wire covering material) forming the conductive yarn 10 is heated and melted and removed by heat received from a solder iron (for example, 320 ° C. to 380 ° C.) whose temperature has been raised to 250 ° C. or higher. become. In addition, this insulating material (coating material) is required to have non-conductivity. In addition, those having flexibility and stretchability are recommended.

  That is, for this insulating material (covering material), it is preferable to use a thermoplastic resin having a melting point equal to or lower than the melting temperature of the solder. Soldering can be performed in a short time, and the molten non-conductive coating material is surely burned out or shrunk to ensure reliable conduction without interfering with the solder location. In this case, those having a melting point in the low temperature range are suitable.

However, the selection of the insulating material (coating material) is not limited only to the melting point, and the thickness of the insulating material (coating material) covering the conductive yarn is one of the conditions. For example, even if the melting point of the insulating material (covering material) is high, if the coating thickness is thin, it will melt relatively easily during soldering, so that it can be used as an insulating material (covering material). .
Furthermore, when a heat-fusing tape or a heat-fusing adhesive is used in the conductive harness mounting structure described later, the melting point of this insulating material (coating material) is not particularly limited, but the heat At about 180 ° C., which is higher than the melting point of the fusion material (iron temperature of about 150 ° C.) and lower than the melting temperature of the solder (about 170 ° C. to 250 ° C., here about 200 ° C.). Preferably there is.

  The non-conductive parts (non-conductive part 3 and non-conductive part 4) are formed of non-conductive yarn having heat resistance against the melting temperature of the solder. Here, the heat resistance required for this non-conductive yarn means that it does not ignite or melt even when contacted with molten solder (or a heated solder iron), and does not easily burn out. However, the extent to which scorching occurs is within an allowable range (can be used for forming a non-conductive portion). In short, if it has heat resistance to the extent that the shape remains even after soldering, the function is sufficient. In order to assist in preventing the molten solder from penetrating into the non-conductive portion, it is even more preferable to take measures such as making the knitted structure of the non-conductive portion a dense structure.

  That is, since the enamel lead used as the conductive yarn 10 of the conductive portion (the knitted fabric 1 of the present invention) is resin-coated, it has a characteristic that insulation from the surroundings is ensured. Since the fibers (for example, aramid fibers) used for the non-conductive portions 3 and 4 are excellent in heat resistance, they can withstand the heat of soldering when performing electrical wiring. For this reason, there is a problem that the non-conductive portions 3 and 4 are melted by the soldering heat. The resin coating of the enameled wire of the conductive yarn 10 is skillfully melted and soldered reliably and easily (as will be described in detail later, the metal pin Heat of about 150 ° C., which is an iron intermediate temperature, in order to use a heat-bonding tape or a heat-bonding adhesive in a conductive harness mounting structure to be described later. (The heat application time may be only a few seconds), and neither the resin coating of the enameled wire of the conductive yarn 10 nor the solder is melted.

In the conductive harness and conductive harness structure according to the present invention employing the heat-resistant fiber (for example, aramid fiber) used for the conductive yarn 10 and the nonconductive portions 3 and 4 having such thermal characteristics, as described above. In addition, the metal piece (metal pin 30) and the metal strand of the metal wire (conductive thread 10) are joined by soldering. This will be described in detail.
First, the positional relationship between the conductive yarn 10 and the metal pin 30 will be described. The position of the body 31 of the metal pin 30 with respect to the conductive yarn 10 knitting the conductive stretch knitted fabric 1 (forming a loop in both side view and plan view) is as follows. As shown in FIG. 7B, the conductive yarn 10 is in contact with different loops (here, the second loop P2 and the third loop P3), and (2) in plan view, as shown in FIG. The metal pin 30 is inserted into the conductive elastic knitted fabric 1 (the conductive yarn 10 for knitting) so as to be inserted into the 10 loops 10R. 7 and 8 are schematic views, and FIG. 8 only shows an example of milling.

  The photograph which image | photographed the surface of the actual electroconductive elastic knitted fabric 1 in which the metal pin 30 was inserted in this way is shown in FIG. FIG. 9 corresponds to FIG. 8, but in FIG. 8 (for convenience of illustration), the conductive yarn 10 is represented by a single formation (configuration like a monofilament), but actually, it is shown in FIG. 9. As described above, the conductive yarn 10 is formed of a large number of enamel conductors (configuration like a multifilament).

  As shown in FIGS. 7 to 9, the conductive yarn 10 for knitting the conductive stretchable knitted fabric 1 is formed to knitted the conductive stretchable knitted fabric 1 in a side view or a plan view. The metal pin 30 is inserted into the conductive stretch knitted fabric 1 so as to maintain the loop of the yarn 10. Further, in any of FIGS. 7 to 9, the elastic yarn 11 for knitting the conductive stretchable knitted fabric 1 is formed for knitting the conductive stretchable knitted fabric 1 in a side view or a plan view. The metal pin 30 is inserted into the conductive elastic knitted fabric 1 so as to maintain the loop of the elastic yarn 11. That is, even if the metal pin 30 is inserted into the conductive stretchable knitted fabric 1, the loop of the conductive yarn 10 and the loop of the elastic yarn 11 are maintained. Mechanical properties and structural (mechanical) properties) are not impaired.

  Then, after the metal pin 30 is inserted into the conductive stretch knitted fabric 1 in this manner, soldering is performed from one end of the metal pin 30 (here, the end portion of the head portion 32 and the end portion 33). 33). At this time, the heat due to soldering is conducted in the direction indicated by the arrow X in FIG. 7, and this heat raises the temperature of the insulating material (covering material) covering the conductive yarn 10 to melt the resin coating and melt it. Solder is poured along the metal pins 30. And in the area | region A which is a contact part of metal materials, the trunk | drum 31 of the metal pin 30 and the metal strand (copper wire) of the electrically conductive thread | yarn 10 are joined by solder. In addition, in the region A in which the body portion 31 of the metal pin 30 and the metal element wire (copper wire) of the conductive yarn 10 are joined by solder in this way, they are electrically connected and structurally ( Mechanical) strength is also improved.

  The manner in which the body portion 31 of the metal pin 30 and the metal element wire (copper wire) of the conductive yarn 10 are joined by soldering is also shown in FIG. 7B in the conductive harness shown in FIG. The same applies to the conductive harness structure shown, and the lengths of the body portions 31 of the metal pins 30 are different in these drawings. If the long metal pin 30 is used for the body portion 31, the body portion of the metal pin 30 can be used in both the conductive harness shown in FIG. 7A and the conductive harness structure shown in FIG. 7B. The length of 31 is the same. In particular, it is also preferable to cut the body portion 31 of the unnecessary metal pin 30 after joining in this way. In this case, only the cross section of the small piece head 32 itself or the cut body part 31 appears on the front and back of the conductive stretchable knitted fabric 1.

  In this way, an electronic device or the like using the conductive harness 2 in which the small metal pieces (the head 32, the end 33, or the cut body 31 of the metal pin 30) appear on the front and back of the conductive stretchable knitted fabric 1 When connecting to (for example, an acceleration sensor), it is only necessary to electrically connect (solder) the metal pieces appearing on the front and back of the conductive stretchable knitted fabric 1 and the input / output terminals of the acceleration sensor. The conductive harness according to the present invention and the electronic device can be easily and reliably connected.

Note that the metal pins 30 and the metal strands (copper wires) of the conductive yarns 10 and the metal pins 30 and the input / output terminals of the acceleration sensor may be soldered at a time. In this case, the conductive harness 2 before soldering is in a state before soldering in which the metal pin 30 is inserted into (only) the conductive yarn 10 constituting the conductive stretchable knitted fabric 1.
Next, the conductive harness or conductive harness structure according to the present invention is a technology for realizing sufficient durability both electrically and structurally (mechanically) and attaching the fabric (fabric, base fabric) to the fabric. The conductive harness mounting structure according to the present invention will be described.

  The conductive harness mounting structure according to the present invention is characterized in that the conductive harness or conductive harness structure according to the present invention described above is bonded to a cloth, and preferably, the conductive harness or the conductive harness structure. The entire attachment surface of the harness structure is adhered to the cloth and adhered. More specifically, it is characterized in that the entire attachment surface of the conductive harness or the conductive harness structure is adhered and adhered to the fabric with a heat-sealing tape having elasticity.

  As such a heat-sealing tape, a tape in which polyurethane, polyamide, or the like as an adhesive for heat fusion is applied to a stretchable urethane film material or polyamide film material, and melts at about 150 ° C., which is an iron intermediate temperature. Thus, a tape that is fused to the fabric is generally known. As a matter of course, the urethane film material itself having a tape shape does not melt at about 150 ° C., which is the iron intermediate temperature. In addition to the film material, it may be a heat-sealing tape using a non-woven material.

For example, such a heat-sealing tape is coated with a heat-bonding adhesive on the entire surface of a tape-like urethane film material or in the form of dots (dots), and a release paper is provided on one surface thereof. ing. Although not limited, the usage method of such a heat sealing | fusion tape is as follows.
Press the heat-sealable tape with the release paper on it for several seconds to apply heat at the intermediate temperature of the iron by placing the tape surface without the release paper against the mounting surface of the conductive harness or conductive harness structure. When the temperature drops, the release paper is removed, and the surface of the tape from which the release paper has been removed is pressed against the fabric and pressed for a few seconds to apply heat at an intermediate temperature of the iron. When the temperature drops, the fabric-heat-seal tape-conductive harness is formed in layers, and the heat-sealable tape with elasticity allows the entire mounting surface of the conductive harness or conductive harness structure to adhere to the fabric. Will be glued.

  FIG. 10 shows the fabric 40 in which the entire attachment surface of the conductive harness or the conductive harness structure is adhered to the fabric in this way. Here, the conductive harness 2 shown in FIG. 10 (and shown in FIG. 11 described later) is provided with four knitted fabrics 1 in the band width direction, and these are separated by the non-conductive portion 3, Further, non-conductive portions 4 are provided on both sides of the knitted fabric 1. As shown in FIG. 10, the conductive harness 2 is not limited to the one that is linearly bonded to the fabric, and may be bonded to the fabric in a curved shape, or that is bonded to the fabric so as not to overlap. However, the present invention is not limited thereto, and it may be overlapped and adhered to the fabric.

Furthermore, the adhesive for heat fusion may be applied to both sides of the tape-like urethane film material of the heat-sealing tape in a dot shape (dot shape) instead of the entire surface. The entire mounting surface of the conductive harness 2 is adhered to the fabric in a tight manner.
Also, instead of heat-sealing tape, heat-bonding adhesive is applied to the entire mounting surface of the conductive harness 2 or in the form of dots (dots), and heat is applied at the iron medium temperature as described above. Then, the entire mounting surface of the conductive harness or the conductive harness structure may be brought into close contact with the cloth. Further, it may be a heat-sealing tape, an adhesive for heat-sealing, or a dot-like (dot-like) shape or a web-like shape (net-like shape).

  In the present invention, in the case where the entire mounting surface of the conductive harness or conductive harness structure according to the present invention is adhered and adhered to the cloth, the entire mounting surface is not only the entire part of the mounting surface but also the mounting surface The partial part (dotted part) is also included. That is, even when the conductive harness or the conductive harness structure according to the present invention is repeatedly stretched after being bonded to the cloth, the conductive harness or the conductive harness structure is disconnected, the cloth (base cloth) is damaged, and the cloth ( As long as the three of the conductive harness or the peeling of the conductive harness structure from the base fabric) can be sufficiently suppressed and sufficient durability can be realized, the entire mounting surface in the present invention is the This includes not only the entire area, but also a partial area (dot (dot), cobweb, net (network)) on the mounting surface.

Next, a conductive harness structure and a conductive harness mounting structure according to the present invention will be described more specifically with reference to FIG. FIG.11 (b) is an enlarged view of the area | region B in Fig.11 (a).
As shown in FIG. 11, this specific example uses a conductive harness mounting structure according to the present invention for a glove (working glove 50) with open fingertips (5 fingers), and the conductive harness according to the present invention. A structure is attached, and the movement of the hand of the worker wearing the work glove 50 is detected. In addition to such gloves, using the conductive harness mounting structure according to the present invention, the object to which the conductive harness or conductive harness structure according to the present invention is attached is not limited to clothes, There are hats and bags.

  The work glove 50 is provided with a processing unit 70 including a gyro sensor, a power supply unit, a communication unit, a memory unit, and an arithmetic unit for executing a program on the back of the hand of the work glove 50, and a thumb (first The acceleration sensor unit 60 is provided on the (finger) portion and the index finger (second finger) portion. Electronic devices that are attached to the work glove 50 including a gyro sensor and an acceleration sensor are common.

  The two acceleration sensor units 60 include a sensor 62 and four input / output terminals 64. The input / output terminals 64 are inserted into the corresponding conductive stretchable knitted fabric 1 in the harness 2 and joined by soldering. The pins 30 are electrically and structurally (mechanically) connected by soldering. The harnesses 2 connected to the two acceleration sensor units 60 are connected to the processing unit 70 via a branch (merging) shown in the region B. In this case, I2C (Inter-Integrated Circuit) communication is used as a communication method between the two acceleration sensors 60 and the processing unit 70. Even if the data lines are merged, each acceleration sensor 60 Can be acquired by the processing unit 70. For this reason, as shown in more detail in FIG. 11B, the branching (merging) in the region B is realized by using the conductive harness structure according to the present invention.

  As shown in FIG. 11 (b), this conductive harness structure has at least two knitted fabrics shown in FIG. 1 (a) overlapped (here, two), and a small metal piece (for example, metal pin 30). The first conductive harness (here, the upper conductive harness 2U) corresponding to the metal wire (conductive yarn 10) and the first conductive harness (upper conductive harness 2U) corresponding to the metal wire (conductive yarn 10). The surface of the first conductive harness (upper conductive harness 2U) and the second are connected to the metal wire (conductive yarn 10) of the second conductive harness (here, the lower conductive harness 2D). The conductive harness (lower conductive harness 2D) is provided so as to penetrate through the back surface. In this case, since the longitudinal directions of the conductive harnesses are shifted so as to be directed in different directions, the upper conductive harness 2U and the lower conductive harness 2D intersect each other, and the branch (merging) Aspects can be realized.

More specifically, this conductive harness structure

(D) The knitted fabric 1D knitted with the conductive yarn 10 in the upper conductive harness 2U and the knitted fabric 1D knitted with the conductive yarn 10 in the lower conductive harness 2D are joined by the metal pin 30D.
Metal pins 30A, 30B, 30C, and 30D are provided on the upper conductive harness 2U and the lower conductive harness 2D, respectively, through the surface of the upper conductive harness 2U and the back surface of the lower conductive harness 2D. Yes.

  As described above, when the conductive stretch knitted fabric 1 according to the present invention, the conductive harness 2 as shown in FIG. 2 and the conductive harness 2 are employed, the conductive harness 2 as the wiring member is actually used as the fabric ( Fabrics that can realize sufficient connection technology (conducting harness), wiring member handling technology (conducting harness structure), and sufficient durability when used on fabrics and base fabrics) The mounting structure (conducting harness mounting structure) has been described. The human body motion detection wear according to the present invention to which the conductive harness 2, the conductive harness structure, and the conductive harness mounting structure are suitably applied will be described in detail.

The human body motion detection wear will be described using the work glove 50 shown in FIG. 11 as an example. Here, since the conductive harness 2, the conductive harness structure, and the conductive harness mounting structure in the work glove 50 are as described above, the other structures will be described in detail below.
FIG. 11 shows a working glove 50 which is a specific example of the human body motion detection wear according to the present invention, and FIG. 12 is a control block diagram thereof. With reference to these drawings, a work glove 50 as human body motion detection wear will be described. Region B in FIG. 12 corresponds to region B in FIG.

  Referring to FIGS. 11 and 12, this working glove 50 includes a gyro sensor module 72 (first detection means), a power supply unit 74 including a battery charging circuit and a battery, and a communication (wireless) unit. A processing unit 70 (control means for controlling the entire work glove 50) including a memory unit 76 and a calculation unit 78 for executing a program is provided on the back of the hand of the work glove 50, and a thumb (first The acceleration sensor module 60F (same as the acceleration sensor unit 60 and the second detection means) in the first finger portion and the acceleration sensor module 60S (the same as the acceleration sensor unit 60 in the second finger) portion and the second Detection means). In the following description, the acceleration sensor module 60F and the acceleration sensor module 60S are both the same as the acceleration sensor unit 60, and may be collectively referred to as the acceleration sensor module 60 in some cases.

  As described above, the illustrated portion of the electrical equipment is connected by the conductive harness 2. Here, the acceleration sensor module 60 (which is at least one) out of the gyro sensor module 72 as the first detection means and the acceleration sensor module 60 as the second detection means and the processing unit 70 are connected to the conductive harness 2. Connected by. The conductive harness 2 is bonded to the fabric constituting the work glove 50. The acceleration sensor module 60 </ b> F and the acceleration sensor module 60 </ b> S are bonded to the fabric constituting the work glove 50 via the conductive harness 2.

  In the present invention, the acceleration sensor module 60 </ b> F and the acceleration sensor module 60 </ b> S are bonded to the fabric constituting the work glove 50, though the conductive harness 2 is interposed. The vertical relationship between the acceleration sensor module 60F and the acceleration sensor module 60S and the conductive harness 2 may be the reverse of the state shown in FIG. 11, and in this case, the cloth and the acceleration sensor constituting the work glove 50 from below. The module 60F, the acceleration sensor module 60S, and the conductive harness 2 are formed, and the acceleration sensor module 60F and the acceleration sensor module 60S are bonded (directly) to the fabric constituting the work glove 50.

Further, the gyro sensor module 72, the acceleration sensor module 60F, and the acceleration sensor module 60S are triaxial sensors and are known sensors. Therefore, these sensors themselves will not be described in detail here.
This work glove 50 is a human body motion detection wear that is worn by a person on his / her hand and detects the motion of a human finger. First detection means provided at the position of the wear corresponding to the first part (here, the back) in the human body (here, the back part of the working glove 50), and detects the first physical quantity for the first part. (Here, a gyro sensor 72, which is an example of a sensor that detects an angle, an angular velocity, and an angular acceleration), and a second part (here, a first finger (thumb) and a second finger (via a first part and a joint)) Second detection means (here, speed and speed) provided at the position of the wear corresponding to the index finger)) (here, the thumb part and the index finger part of the working glove 50) and detecting the second physical quantity of the second part. Acceleration sensor module 60F and acceleration sensor module 60S), which are examples of sensors for detecting acceleration, signals output from the first detection means, and outputs from the second detection means. And the conductive harness 2 through which at least one of the generated signals (here, the signal output from the second detection means) flows electrically, and as described above, the conductive harness 2 is wear. It is adhered to the work glove 50. Although not limited thereto, in this working glove 50, the joint between the first part and the second part is a joint at the base of the finger and has five middle hands on the back of the hand. It is assumed that it is an MP (metacarpal phalangeal joint) joint between a bone and a bone at the base of a finger and five proximal phalanges.

As will be described in detail later, the second detection means (here, the acceleration sensor module 60F and the acceleration sensor module 60S) uses the first physical quantity detected by the first detection means (here, the gyro sensor 72) as a reference (reference). A second physical quantity used as a reference plane is detected.
More specifically, the first detection means (here, the gyro sensor 72) is used as a reference plane in order to use the first portion (here, the back) as the reference plane of the second portion (here, the finger). A signal for detecting at least one of absolute position and tilt is output. The second detection means (here, the acceleration sensor module 60F and the acceleration sensor module 60S) detects at least one of the relative position and the inclination with respect to the reference plane for the second part (here, the finger). The signal is output.

  In this case, at least one of the absolute position and the inclination of the finger is processed by the arithmetic unit 78 so that the back is a plane and the plane is a reference plane, and the reference plane corresponds to the ground plane of the acceleration sensor. Can be detected. This is because the rotation direction of the back cannot be determined only by the acceleration sensor because the rotation cannot be detected by the acceleration sensor, but the rotation direction of the back can be detected by the gyro sensor and the movement of the finger can be detected based on that. become. In this way, it is not necessary to provide an expensive gyro sensor for each finger.

Hereinafter, the working glove 50 will be described more specifically.
As described above, the gyro sensor module 72, which is an example of the first detection means, is provided on the back part of the work glove 50 as shown in FIG. 11, and at least any of the absolute position and inclination with the back as a reference plane. A signal indicating an angle, an angular velocity or an angular acceleration for detecting this is output to the arithmetic unit 78 of the processing unit 70.

  Further, as described above, the acceleration sensor module 60, which is an example of the second detection means, is provided on the first finger part (thumb part) and the second finger part (index finger part) of the work glove 50 as shown in FIG. One (two in total) is provided, and a velocity or acceleration for detecting at least one of the relative position and inclination of the first finger (thumb) and the second finger (index finger) with respect to the reference plane is set. The signal shown is output to the arithmetic unit 78 of the processing unit 70. Note that the first finger part (thumb part) and the second finger part (index finger part) in the work glove 50 are both parts on the hand side of the MP joint described above.

  As described above, the gyro sensor module 72 is illustrated as an example of the first detection unit. However, in addition to the gyro sensor module 72, the first detection unit includes an acceleration sensor module as shown in FIG. May be included. That is, an acceleration sensor is used in combination with the gyro sensor as the first detection means. In this way, the gyro sensor alone cannot determine the initial posture, but the acceleration sensor detects the gravitational acceleration, thereby determining the horizontal plane and calculating the initial posture. Then, a change from the initial posture of the detected reference surface is detected by the gyro sensor, and a relative angle with respect to the reference surface is acquired using the angle detected by the second detection means (the illustrated acceleration sensor module 60). Therefore, at least one of the absolute position and the physical quantity of the inclination of the second part can be detected with high accuracy.

Furthermore, if a geomagnetic sensor is used in combination as the first detection means, the orientation in the horizontal plane can be determined. Thus, by using the acceleration sensor and the geomagnetic sensor together with the gyro sensor, an error (integration error, etc.) due to the drift of the gyro sensor or the like can be corrected, and high measurement accuracy can be realized.
As described above, the first detection means is not particularly limited as long as it includes a gyro sensor, and even if it is a sensor module including only a gyro sensor, the first detection means includes a gyro sensor and an acceleration sensor. Even if the sensor module is a sensor module configured by a gyro sensor, an acceleration sensor, and a geomagnetic sensor, the sensor module is configured by a gyro sensor and a sensor other than the illustrated acceleration sensor and geomagnetic sensor. But it doesn't matter.

Here, instead of the acceleration sensor module 60, the following sensors may be used.
The first alternative sensor is a stretch sensor using a conductive elastic knitted fabric having a variable property of electrical resistance described in Japanese Patent Application No. 2015-140652 according to the applicant's application. This conductive stretch knitted fabric is a knitted fabric in which the direction in which the loops are connected in the knitted structure is defined as the course direction or course, and the loop is formed of conductive yarns and the elastic yarns are tightened in the course direction. When the knitted fabric is not stretched, the conductive yarn loops adjacent in the course direction are kept in contact with each other by the tightening force of the elastic yarn, while the knitted fabric is stretched in the course direction when the knitted fabric is stretched in the course direction. The loops can be separated from each other against the tightening force of the elastic yarn.

The second alternative sensor is a stretch sensor using a conductive stretch yarn described in Japanese Patent Application No. 2006-002803, which is filed by the present applicant. This conductive stretch yarn is composed of a covering yarn using an elastic yarn for the core portion and a conductive yarn for the covering portion covering the core portion, and the electric resistance value of the covering yarn correlates with the elongation rate of the covering yarn. It has variable resistance characteristics that change.
When such a work glove 50 is worn by a picking worker at a distribution center, the picking worker's picking operation can be detected. For example, the operation of picking by the picking worker is detected by the work glove 50 together with the management of the location of the shelf (the management of the position information of the shelf and the management of the state of the product placed on the shelf). In this way, when picking the specified product from the shelf, the picking operator can detect the action of picking the product from the shelf, and can detect a picking error from the shelf by comparing with the picking instruction. The picking operator can be notified of the mistake by an alarm or the like.

In the description of FIG. 13 described above, the human body motion detection wear according to the present invention is described as clothing from the viewpoint of being worn by a person.

The joining method is not limited to adhesion or stitching, and any joining method may be used.
