Description

  The present invention is not limited to a human body such as a head or neck of a spectacle wearer's head or an accessory wearer, but also a wearable object such as an animal body, equipment, or other article, and glasses, accessories or other attachments. In particular, even when the shape and size of the mounted body change, the member that can fit the mounting portion of the mounted object to the mounted body when the mounting body is mounted is deformed following the change. It is related with the shape adaptive member which can maintain a fitting state by doing.

As an example of a member required to adapt the shape of the mounting portion of the mounted object to the shape and size of the mounted body when mounting the mounted object on the mounted body, a temple of a spectacle frame can be cited. The temple is fitted to the temporal region (attachment body) of the spectacle wearer, thereby preventing the spectacle frame (attachment) from dropping or slipping off.
However, since the spectacle frames are generally mass-produced in accordance with the unified standard, there is a problem that when the shape and size of the head of the spectacle wearer changes, the temple or modern does not fit properly to the head of the spectacle wearer. Arise. In order to solve such a problem, a spectacle frame is finely adjusted in accordance with the spectacle wearer at a spectacle store.

Spring hinge glasses are also known in which a spring property is supported on the hinge portion of the temple base, and the temple is pressed against the temporal region by the spring force of the hinge portion to prevent dropping or displacement.
FIG. 5 is a diagram for explaining the operation of the spectacle frame in which the hinge portion is supported by the spring property. Temples T are attached to the left and right ends of the front frame F holding the lens by a hinge C so as to be foldable. A hinge is incorporated in the hinge C, and a spring force is applied to the left and right temples T and T so as to sandwich the head H of the eyeglass wearer.

  In the spectacle frame provided with this kind of spring hinge C, the spectacle frame in which the shape of the temple T and the width between the left and right temples T and T are adjusted so as to fit the head H1 having the head width L1 is used. When the wearer of the head H2 having the width L2 (L1 <L2) is worn, the width between the left and right temples T and T expands according to the head width L2, and the head H2 of the spectacle wearer is sandwiched from the left and right.

  However, since the left and right temples T and T are only linearly expanded with the hinge C as a fulcrum when the head width is changed from L1 to L2, as shown by the phantom line in FIG. There is a problem that the contact length between the portion H2 and the temple T after the expansion is reduced, and the fit is lowered. Further, when the width between the left and right temples T, T is expanded to L2 in accordance with the head H2, the holding force by the spring of the hinge C is increased correspondingly, which causes inconvenience such as giving a feeling of strangeness to the spectacle wearer.

  In order to solve such problems, for example, as in a spectacle frame described in Patent Document 1, an elastic portion (portion indicated by reference numeral 45 in Patent Document 1) is provided on the temple, and the width of the head of the spectacle wearer is determined. Accordingly, a spectacle frame is also known in which a temple (elastic temple) is elastically deformed at the elastic portion to improve fit while suppressing discomfort even for spectacle wearers with different head widths.

  In the spectacle frame having such an elastic temple, when the wearer's head width changes from L1 to L2 as in the case shown in FIG. 5, the elastic portion is elastically deformed according to the stress acting on the portion. To do. The deformed form is not a straight line like the hinge C having the spring property of FIG. 5, but is an arcuate shape curved inward, so that even if the size or shape of the head changes, the wearing of glasses There is an advantage that a relatively long contact length can be maintained between the person's heads H1 and H2. In addition, if the rear end portion of the elastic temple is largely curved in advance along the heads H1 and H2 of the spectacle wearer, there is an advantage that the contact length can be further extended.

However, even with this type of spectacle frame, there is still a problem that the contact state of the portion that contacts the temporal region is still insufficient, and the point wears partly, causing the spectacle wearer to feel uncomfortable. It was. Further, in this type of spectacle frame, since the elastic portion (the portion indicated by reference numeral 45 in Patent Document 1) is exposed, the shape of the elastic portion must be designed in consideration of the design of the spectacle frame. There is also a problem that it is difficult to design an elastic part having a good fit.
For this reason, in such an elastic temple, a spectacle frame is proposed that attempts to supplement the suppression of dropout and displacement with a hinge having a spring property while suppressing the pressing force of the portion in contact with the temporal region as a whole. .

JP 2008-96598 A

  The present invention has been made in view of the above-described problems of the prior art, and can maintain high fit by maintaining a good contact state even when the shape or size of the mounted body changes. An object of the present invention is to provide a shape-adaptive member that can effectively suppress the drop-off and displacement of the attachment.

As described above, if the temple is made elastic by using a material such as β titanium as in the spectacle frame described in Patent Document 1, even if the shape and size of the head of the spectacle wearer changes slightly. Following this, a change in the contact length between the temple (elastic temple) and the temporal region of the spectacle wearer can be suppressed to some extent, and the fit can be maintained. However, as described above, even such a conventional elastic temple has a problem that the fitting property is still insufficient.
As a result of intensive studies by the inventors of the present invention, the reason why the above-described conventional elastic temple has insufficient fit is that the portion that supports elasticity is only the first half of the elastic temple, and the portion that supports elasticity is I came to the conclusion that I was exposed to design constraints.
Therefore, it is possible to control the elasticity over the entire length of the temple, and to make the core material inconspicuous by covering the core material with other members, so that the design is not restricted. In this way, even if the shape and size of the head of the spectacle wearer changes slightly, a contact length of a certain level or more can be maintained, and the dropout and displacement can be effectively prevented without causing the spectacle wearer to feel uncomfortable. The present invention has been conceived as a temple for a spectacle frame that can be suppressed is obtained.

  Furthermore, the inventor of the present invention paid attention to an elastic member such as a coil spring in achieving the object of the present invention. An elastic member such as a coil spring is always subjected to a restoring force for returning to its original shape. And although an elastic member such as a coil spring is difficult to maintain an arbitrary shape by itself, it is not only possible to change the shape to an arbitrary shape by combining with a core material, but it is also easy to maintain the shape. There is an advantage. The inventor of the present invention has come up with the present invention by combining with an elastic core material from the advantages of such a coil spring.

  Specifically, as described in claim 1, the present invention is a shape-adaptive member that is formed from an elastic member that has elasticity in the bending direction, and whose shape changes so as to be in close contact with the mounted body, The elastic member formed in a hollow shape, and a core member that is fitted into the hollow hole of the elastic member and determines the shape of the elastic member in cooperation with the elastic member. The core member is inserted into at least the contact portion of the elastic member so as to come into contact with the contact portion with the mounting body at a predetermined length, and the mounted portion that becomes a reference in cooperation with the elastic member A shape that is partly or entirely curved in advance along the shape of the body, has an elastic force that acts in the opposite direction to the elastic force that acts on the elastic member, and is different from the reference shape Or when mounted on another mounted body of a different size Is a structure in which one or more elastically deformable portions to be elastically deformed so that the elastically member cooperating to maintain the contact state of the fixed length relative to the contact portion between the object to be mounted body.

According to this configuration, for example, an elastic member such as a coil spring that has elasticity in a direction to return to a straight line, the core material follows the shape of a mounted body such as the head of a spectacle wearer. Use one that has an elastic force in the direction of movement. The core member is plastically deformed in advance according to the reference shape of the body to be mounted as a reference, and the elastic member and the core member in cooperation with the elastic force of the elastic member having an elastic force in the opposite direction. Matches the reference shape. As described above, in the mounted body of the reference shape, the elastic member and the mounted body are in contact with each other at a certain length, and the core material is elastic when a certain bending force is applied. By providing one or a plurality of elastic deformation portions having different deformation amounts, the contact state of the predetermined length can be maintained even when the elastic member is mounted on another mounted body having a different shape or size. Is possible. The form and arrangement of the elastically deformable portion vary depending on the type, shape or size of the mounted body, but can be determined by experiment or empirical rule. Since the core material is covered with the elastic member, the shape adaptive member of the present invention has an advantage that the shape of the core material does not appear in the appearance, and therefore the shape of the core material can be freely selected.
If it has such an action, as described in claim 2, the core material may be divided into a plurality at the contact portion, and a plurality of core materials are inserted into the contact portion. Also good.

As described in claim 3, as the elastic member, for example, a winding obtained by winding a metal wire in a coil shape, a stranded wire obtained by twisting a plurality of metal wires, or a knitted wire obtained by knitting a plurality of metal wires is used. be able to. Alternatively, a combination of two or more of these may be used. As such an example, for example, a wire in which the stranded wire or the knitted wire is covered outside the winding.
Examples of the arrangement of the elastically deforming portions in one core material include one in which portions that are easily elastically deformed and portions that are not easily elastically deformed are alternately arranged. In addition, as described in claim 4, the amount of elastic deformation when a certain bending force is applied to one elastic deformation portion may be non-uniform.
In addition, as described in claim 5, the cross-sectional shape or diameter of the elastic deformation portion may be changed for each of the plurality of elastic deformation portions or within one elastic deformation portion.

In the present invention, the elasticity of the shape adaptive member is determined by the cooperation of the elastic force of the elastic member and the elastic force of the core member. Therefore, as described in claim 6, at least one of the elastic member and the core material can be replaced, and various combinations of the elastic member and the core material can be changed to obtain an optimal combination. Is possible.
For example, when the shape-adaptive member of the present invention is applied to a temple of a spectacle frame, the elastic member and the core material are used when it is desired to adjust the pressing force of the temple during normal use and during exercise. Any one or both of these may be replaced.
The shape-adapting member of the present invention is not particularly limited as long as it is a member that needs to be fitted to the mounted body. However, as described in claim 7, the shape-adaptive member is suitable for a spectacle component constituting a spectacle frame. It can be applied to temples, modern, bridges, or wisdoms.

  According to the present invention, even if the shape and size of the wearable body such as the head of the spectacle wearer changes with respect to the reference shape and the reference size, the wearable body is fixed to the wearable body for a certain length according to this change. Thus, it is possible to provide a shape-adaptive member that fits moderately so as to come into contact with each other. When the present invention is applied to, for example, a temple of a spectacle frame, the temple can always be brought into contact with the head of the spectacle wearer with the optimum contact length by the cooperation of the core member and the elastic member. It is possible to provide eyeglass frames that are difficult to drop off.

In addition, for example, in an eyeglass dealer, several types of temple eyeglass frames that match the reference head shape and size are prepared, or multiple types of elastic members and cores are appropriately combined. Thus, the number of times that the temple shape needs to be fine-tuned according to the individual spectacle wearer is reduced, and the burden on the spectacle store can be greatly reduced.
The shape-adaptive member of the present invention is not limited to a spectacle frame, but can also be applied to a bracelet, an accessory attached to the body, or other attachments.

DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described in detail with reference to the drawings.
FIG. 1A is a diagram showing an embodiment of a shape-adaptive member of the present invention, FIG. 1B is a diagram showing an example of a core material used in the shape-adaptive member of FIG. (ii) (iii) is a figure which shows an example of the cross-sectional shape of the II direction of (a), (d) (i) (ii) (iii) is the elastic deformation in the II-II direction of (b). It is a figure which shows an example of the cross-sectional shape of a part.
In the following description, it is assumed that the shape-adaptive member is used for a temple of a spectacle frame that is a wearing body, and when the spectacle frame is attached to the head of a spectacle wearer that is a wearing body, The description will be made assuming that the shape is elastically deformed so as to be adapted to the head of the eyeglass wearer.

In the example of FIG. 1, the shape adaptable member 1 includes a winding 12 as an elastic member and a linear core member 11 inserted into the hollow hole 12 a of the winding 12. The diameter of the hollow hole 12a is not particularly limited as long as the core material 11 can be inserted, but is preferably substantially the same as the maximum outer diameter of the core material 11.
The winding 12 is a coil spring shape in which a metal wire is densely wound in a coil shape, and has a shape along the straight axis Z (the shape in FIG. 1A) as a basic shape. As the metal wire, a resin material such as a super elastic resin can be used in addition to a metal having elasticity such as stainless steel, spring steel, Ti or Ti alloy, NT alloy, and beryl copper. When the winding 12 is bent by applying a bending force in a direction crossing the axis Z, an elastic force is generated on the winding 12 to return to the basic shape. The magnitude of the elastic force in the return direction generated in the winding 12 can be adjusted by the material and diameter of the metal wire.
The cross-sectional shape of the winding wire 12 is not limited to the circular shape as shown in FIGS. 1C and 1I. For example, the winding 12 has an elliptical shape as shown in (c) and (ii) and a square shape as shown in (c) and (iii). Also good.

  The core material 11 can be formed of a resin material such as a super elastic resin in addition to a metal having elasticity such as stainless steel, spring steel, Ti or Ti alloy, NT alloy, and beryl copper similarly to the winding wire 12. The core member 11 cooperates with the winding wire 12 to cause the temple to extend over a certain length with respect to the head due to a bending force generated when the spectacle frame is mounted on the head of the spectacle wearer. A contact state is maintained, and the elastic force which pinches | interposes the said head from right and left is generated in a temple. Here, the “constant length” when the shape-adaptive member of the present invention is applied to a spectacle frame refers to a length with which the temple contacts from the temple portion of the spectacle wearer to the back of the head.

  In order to maintain the contact state of the predetermined length even if the size and shape of the head changes, the core material 11 of this embodiment is configured as shown in FIG. The elastic deformation portions 111, 112, 113... Of lengths S1, S2, S3... Elastically deformed in a curved shape by the bending force generated when the spectacle frame is attached to the lens frame, and almost depending on the bending force. The non-deformable portions 114, 115, 116,... Having lengths H1, H2, H3,. In this embodiment, the elastic deformation portions 111, 112, 113,... Are made smaller in diameter than the non-deformation portions 114, 115, 116, and the lengths S1, S2, S3,. By appropriately selecting the dimensions of the lengths H1, H2, H3,..., The deformation mode of the core material 11 is adjusted so that the contact state with the predetermined length can be maintained.

  In order to adjust the deformation mode of the core material 11 and maintain the contact state with the predetermined length, not only the cross-sectional diameter of the elastic deformation portions 111, 112, 113. Is also possible. Fig. 1 (d) shows an example of the cross-sectional shape of the II-II part, but an elliptical or rectangular cross-sectional shape such as (ii) (iii) is better than a circular cross-sectional shape such as (i). The core material 11 is difficult to bend, that is, the elasticity can be increased. In addition, there is an advantage that the bending direction can be regulated by appropriately selecting the cross-sectional shape.

That is, as shown in FIGS. 1D and 1I, the elastically deforming portions 111, 112, 113... Having a circular cross section can be elastically deformed in all directions. On the other hand, if the cross sections of the elastic deformation portions 111, 112, 113,... Are elliptical as shown in FIGS. 1 (d) (ii), the elastic deformation of the elastic deformation portions 111, 112, 113,. If it is restricted in the direction of the part (vertical direction in the illustrated example) and is rectangular as shown in FIGS. 1 (d) and (iii), the direction of elastic deformation is substantially in one direction (horizontal direction in the illustrated example). Limited.
As described above, the elastic deformation portions 111, 112, 113,... Are combined by combinations of the diameter and length of the elastic deformation portions 111, 112, 113,. 112, 113... The degree and direction of elastic deformation can be freely adjusted.

Of course, in each of the elastically deforming portions 111, 112, 113,..., The cross-sectional diameter and the cross-sectional shape may be constant over the entire lengths S1, S2, S3,. , S3... The cross-sectional diameter and the cross-sectional shape may be changed at an intermediate position. The material of each of the elastic deformation portions 111, 112, 113... May be changed, or the elasticity may be changed by annealing or the like.
The above-described elastically deformable portions 111, 112, 113,... Can be formed by swaging, pressing, or cutting an intermediate portion of the core material 11.

The shape-adaptive member 1 is formed by inserting the core material 11 having the above configuration into the hollow hole 12a of the winding 12 as an elastic member and fixing both ends of the winding 12 to the core material 11. Prior to inserting the core material 11 into the hollow hole 12a of the winding wire 12, the core material 11 is plastically deformed in accordance with a preset shape, for example, the shape of the head of the spectacle wearer serving as a reference. Since the winding 12 has a coil spring shape, the winding 12 is shaped according to the shape of the core 11 by inserting the plastically deformed core 11 into the hollow hole 12 a of the winding 12.
In addition, since the shape of the shape adaptive member 1 is determined by the cooperation of the elastic force of the winding wire 12 that is to be restored to a linear shape and the elastic force of the core member 11 that is to be restored to a preset shape. The shape of the core material 11 after plastic deformation is the head of the spectacle wearer serving as a reference, and the shape-adaptive member 1 composed of the core material 11 and the winding wire 12 is applied to the head over the entire length of the contact portion. Select a shape that touches.

The winding 12 can be fixed to the wisdom of the spectacle frame by brazing, welding, bonding, or the like. Windings of different elasticity and shape can be attached to or detached from the wisdom by means of a spiral such as a bolt or nut, or by fixing the core 11 to the wisdom and making it removable with respect to the core 11 12 can be exchanged.
Further, the core material 11 may be inserted into the winding 12 to fix both ends thereof, or the core material 11 may be fixed to the wisdom. Examples of the fixing method include brazing, welding, adhesion, spirals such as bolts and nuts, and stoppers.
By using a spiral such as a bolt or nut or a stopper, the core member 11 can be exchanged with respect to the winding wire 12.
In this way, by making either or both of the winding wire 12 and the core material 11 interchangeable, for example, the pressing force on the head of the spectacle wearer according to the difference in use such as sports and daily use. It is possible to change the size of the wire, to replace the winding 12 with a different design, coloring, pattern, etc., or to replace the winding 12 with another elastic member such as a stranded wire or a knitted wire.

  Furthermore, another winding 12 may be fitted around one or more layers around the winding 12, or another elastic member such as a stranded wire or a knitted wire may be fitted. Moreover, you may provide the decoration material and coating | covering material which can be deform | transformed integrally with the shape adaptive member 1. FIG. For example, a heat-shrinkable pipe may be fitted around the winding 12 and heat-shrinked.

By the way, when a spectacle frame in which the shape-adaptive member 1 of this embodiment is applied to the temple portion is worn from the head of the spectacle wearer serving as a reference to the head of another spectacle wearer having a different size or shape. In any spectacle wearer, in order to maintain a constant contact length between the head and the temple, it is necessary to appropriately select the form of elastic deformation of the core member 11.
The form of elastic deformation of the core material 11 can be obtained by experiment and experience. For example, a plurality of pressing force measurement points are provided at the contact portion between the temple and the head, and the elasticity of the core material 11 is determined from changes in the pressing force at each pressing force measurement point before and after the shape and size of the head change. The form of deformation, that is, the shape of the core material 11 (position, length, cross-sectional shape, cross-sectional diameter, etc. of the elastic deformation portions 111, 112, 113) can be determined.
FIG. 2 is a diagram showing an embodiment in which the shape-adaptive member 1 of the present invention is applied to a temple of a spectacle frame, and when the temple is elastically deformed according to a change in the size and shape of the head of the spectacle wearer. It is a top view of the spectacles frame which shows a mode. The temple T is provided with a plurality (five in the illustrated example) of pressing force measurement points A to E at equal intervals between one end and the other end of the contact portion. 3A is a graph showing the distribution of the pressing force at the pressing force measurement points A to E on the temple T of the eyeglass frame of FIG. 2, and FIG. 3B is a pressing force measuring point A based on the graph of FIG. It is the schematic which shows an example of the shape of the core material for making distribution of pressing force of -E uniform.

The core material 11 is a reference value in which the pressing force at each of the pressing force measurement points A to E at the contact portion where the temple T is in contact with the head H1 (width L1) of the reference spectacle wearer is substantially equal. The shape is determined in advance so as to be plastically deformed. If the pressing force at each of the pressing force measurement points A to E is substantially equal, the temple T is in contact with the head H1 of the spectacle wearer over the entire length of the contact length Z1 at the contact portion. I can say that.
Next, the spectacle frame is mounted on the head H2 (width L2) of another spectacle wearer, and the change in the pressing force at each of the pressing force measurement points A to E is measured. FIG. 3A is a graph showing the amount of change in the pressing force at each portion of the pressing force measurement points A to E with respect to the reference value. That is, at the pressing force measurement points A, C, and E, the pressing force is increased by P1, P2, and P3, respectively, at the pressing force measurement point B, the reference value is substantially decreased, and at the pressing force measurement point D, the pressing force is decreased by P4. And

Therefore, at the pressing force measurement points A, C, and E, the diameter of the core material is reduced before and after that so as to reduce the pressing force. Moreover, since it can be estimated that the temple is floating (not in contact) from the head H2 by bending at the pressing force measurement point D, it is easy to elastically deform by reducing the diameter of the core material at the pressing force measurement point D. The pressing force measurement point D is also brought into contact with the head H2. FIG. 3B schematically shows the shape of the core 11 formed from these examination results. After selecting the shape as shown in FIG. 3B, the spectacle frame is attached to the head H1 as the reference again, and the pressing force at each of the pressing force measurement points A to E becomes almost equal. In this way, the shape of the core material 11 may be adjusted.
By repeating the above procedure, even if the head width changes from L1 to L2, the contact lengths Z1 and Z2 with the temple T between the heads H1 and H2 can be hardly changed.

Thus, in the present invention, for example, in the temple T of the spectacle frame, the contact length between the temple T and the heads H1 and H2 is constant even if the shape and size of the head changes to a size and shape different from the reference. Therefore, it is possible to obtain a higher fit than an elastic temple as described in Patent Document 1. In addition, a linear member can be used as the core material 11, and the core material 11 is inserted into the hollow hole 12 a of the winding (elastic member) 12. It does not appear, and it becomes possible to obtain a higher fit by freely selecting the form of the core material 11.
For this reason, a spectacle store or the like only needs to prepare a plurality of types of spectacle frames having a temple T having a reference shape or size, and the fine adjustment work for spectacle wearers at the spectacle store or the like is reduced. This makes it possible to reduce the burden on eyeglass stores.

  FIG. 4 is a cross-sectional view showing another embodiment of the shape-adaptive member of the present invention. In FIG. 4, the core material 11 is hatched for easy understanding of the existence of the space S. In this embodiment, a case where the shape adaptable member 1 is applied to a modern M of glasses is taken as an example. The modern M of this embodiment has a straight portion 12b having a length X at a midpoint. Since the coil spring-shaped winding 12 has an elastic force in a direction to return to the linear state, in this embodiment, the linear portion 12b is provided with a space S in which the core material 11 is not provided by using the elastic force. . In such a space S, the core material 11 is divided at the front side and the rear side of the modern M, or a plurality (two in the illustrated example) of the core material 11 are separated from each other in the space S and inserted into the modern M. Can be formed.

Although preferred embodiments of the present invention have been described, the present invention is not limited to the above description.
For example, in the above description, a winding obtained by winding a metal wire in a coil shape as an elastic member has been described as an example. However, a twisted wire obtained by twisting a plurality of metal wires or a knitted wire obtained by knitting a plurality of metal wires is used. It may be used as an elastic member. Moreover, you may comprise an elastic member by combining these 2 or more types.
In the above description, the shape adaptable member of the present invention is applied to the temple of the spectacle frame. However, the present invention can be applied to other places such as a bridge, wisdom, modern, and rim. Not limited to this, it can also be applied to accessories such as bracelets. Furthermore, the wearable body is not limited to the human body, and even if there is a slight change from the standard shape or size, such as the body of an animal such as a dog or cat, equipment, or other items, the wearable body follows this change. It is also possible to apply to a mounted body that is required to fit.
Furthermore, in another embodiment in FIG. 4, the space S is formed only in the straight line portion 12 b that has a shape that the elastic member is to return (a straight shape in the coil spring-like winding 12). Is not limited to such a straight portion 12b, but may be appropriately formed in a portion where the elastic force of an elastic member such as the winding 12 is to be used as it is.
