Description

  The present invention relates to a screw temporary fixing member.

  For example, when manufacturing automobiles, various parts (particularly, electrical components such as AM filters and AM / FM amplifiers) are fixed to the vehicle body by screws. Usually, an operator performs such screwing work by fixing a part at a predetermined position of the vehicle body with one hand and tightening the screw with a tool such as a screwdriver with the other hand. However, in such a working method, it is difficult to support the screw with both hands because the hands are closed, and as a result, the screw falls off during the work, resulting in a problem that work efficiency is deteriorated.

  Patent Document 1 discloses a screw temporary fixing member (screw temporary fixing holder) for solving such a problem. The screw temporary fix | stop member of patent document 1 has a base and the holding part supported in the state separated from the base by a pair of leg part. Moreover, a hole slightly smaller than the diameter of the screw is formed in the holding portion, and the screw is press-fitted into the hole. As a result, the screw is held in a state of being vertical to the base. Each leg is curved inward so as to be easily deformed.

  Such a screw temporary fixing member is used by fixing the base to a part to be screwed with the double-sided tape. The worker aligns the part to which the screw temporary fixing member is fixed at a predetermined position of the vehicle body, and tightens the screw while pushing the screw with a tool such as a screwdriver. The temporary screw fixing member of Patent Document 1 is configured such that each leg portion is crushed in two inward by tightening the screw. According to such an operation, since the screw is held by the temporary screw fixing member, the conventional problem, that is, the problem of the screw falling off during the operation is prevented, and the parts can be easily and smoothly screwed onto the vehicle body. Can be stopped.

  Thus, according to the screw temporary fixing member of Patent Document 1, the conventional problem can be solved, but the following problem occurs.

  As a first problem, the temporary screw fixing member of Patent Document 1 has a problem in that the temporary screw fixing member is large in structure. The screw temporary fixing member of Patent Document 1 is configured such that each leg is crushed in two inward when the screw is tightened, so that the length of the base and the holding part (of the pair of leg parts) It is necessary to lengthen the length in the separation direction and secure a space for collapse of each leg. As a result, the screw temporary fixing member is enlarged.

  As a second problem, the screw temporary fixing member of Patent Document 1 has a problem that the tightening force by the screw is reduced. The screw temporary fixing member of Patent Document 1 is configured such that when the screw is tightened, each leg portion is crushed in half toward the inside. Therefore, when the screw is tightened, a crushed leg portion is interposed between the holding portion and the base, and a gap is formed between the holding portion and the base (see FIG. 3 in Patent Document 1). . When such a gap is formed, the screw cannot be sufficiently tightened, and the tightening force of the screw is reduced.

<First Embodiment>
First, a first embodiment of the temporary screw fixing member of the present invention will be described.

  1 is a perspective view showing a state in which a screw temporary fixing member according to a first embodiment of the present invention is mounted on a fixed object, FIG. 2 is a perspective view and a cross-sectional view showing the fixed object shown in FIG. 3 is a perspective view of the screw temporary fixing member shown in FIG. 1, FIG. 4 is a cross-sectional view of the screw temporary fixing member shown in FIG. 3, and FIG. 5 is a perspective view of the screw temporary fixing member in a state where the screw fixing is completed. FIG. 6 is a cross-sectional view showing a modification of the temporary screw fixing member shown in FIG. In the following, for convenience of explanation, the upper side in FIG. 5B is also referred to as “upper” and the lower side is also referred to as “lower”.

  As shown in FIG. 1, the temporary screw fixing member 1 is used by being attached to a fixed object 10 screwed to a member 20, and a screw (including screws, bolts, etc.) 7 is temporarily attached to the fixed object 10. Used to stop.

  According to the temporary screw fixing member 1, the screw 7 can be held on the fixed object 10, that is, the screw 7 can be prevented from falling off the fixed object 10 without supporting the screw 7 by hand. Therefore, when the operator fastens the fixed object 10 with a screw, for example, the fixed object 10 is fixed to a predetermined position of the member 20 with one hand and the screw 7 is used with a tool such as a screwdriver with the other hand. By fastening in the screw hole 201 (see FIG. 5) formed in the member 20, the fixed object 10 can be screwed easily and smoothly. Thereby, working efficiency improves remarkably. As will be described later, the temporary screw fixing member 1 is easily deformed when the screw 7 is tightened, and there is no problem in screwing with the screw 7.

  Hereinafter, although the screw temporary fixing member 1 is demonstrated in detail, prior to that, the fixed object 10 is demonstrated easily.

[Fixed object]
The fixed object 10 is not particularly limited, and examples thereof include electronic parts such as an AM / FM tuner, an AM / FM amplifier, a power supply unit, and a motor. The member 20 for screwing the fixed object 10 is not particularly limited, and may be, for example, a car body, a building wall (an inner wall, an outer wall, etc.) or a ceiling.

  As shown in FIG. 1, the fixed object 10 according to the present embodiment includes a housing 11 in which main parts of the electronic components are stored, and a base 12 that supports the housing 11. The housing 11 and the base 12 are each made of a metal material such as aluminum or copper, or various resin materials such as polyethylene, polypropylene, polyvinyl chloride, polystyrene, polyamide, or polyimide.

  The base 12 is formed with at least one insertion hole 13 which is a screw fixing hole through which the screw 7 is inserted. The number and arrangement of the insertion holes 13 are not particularly limited as long as the fixed object 10 can be screwed to a predetermined position, and a plurality of insertion holes 13 may be inserted depending on the shape, size, weight, and the like of the fixed object 10. A hole 13 may be provided.

  The shape and size of the insertion hole 13 are not particularly limited as long as the screw 7 can be inserted, but the insertion hole 13 has a circular shape slightly larger than the outer diameter of the shaft of the screw 7 (the outer diameter at the top of the screw thread: the maximum outer diameter). Preferably there is. Thereby, the screw 7 can be smoothly inserted into the insertion hole 13. Furthermore, it becomes difficult to form a gap between the shaft of the screw 7 and the base 12, and the displacement of the fixed object 10 from a predetermined position due to the gap can be prevented.

  In addition, a pair of grooves 14 and 15 disposed opposite to each other through the insertion hole 13 are provided in the vicinity of the insertion hole 13 so as to extend in the same direction. The grooves 14 and 15 are grooves into which the support portion 2 of the temporary screw fixing member 1 is inserted. The support part 2 is fixed to the fixed object 10 by being inserted into the grooves 14 and 15 so as to slide in the surface direction of the base 12 and engaging with the grooves 14 and 15. At this time, the support portion 2 is preferably inserted into the grooves 14 and 15 from the side far from the housing 11. According to such an insertion direction, the insertion of the support portion 2 into the grooves 14 and 15 is not hindered by the housing 11, and the support portion 2 can be smoothly inserted into the grooves 14 and 15.

  The grooves 14 and 15 can be formed, for example, by forming a “U” -shaped cut in the base 12 and bending or bending a portion inside the cut into a desired shape. According to such a method, the grooves 14 and 15 can be formed integrally with the base 12, and the grooves 14 and 15 can be easily formed.

  Further, a protrusion 16 is formed near the insertion hole 13. The protrusion 16 is a protrusion that engages with a hole 61 formed in the support portion 2 of the screw temporary fixing member 1, and the screw temporary fixing member 1 is positioned with respect to the fixed object 10 by engaging with the hole 61. Do.

  The shape of the protrusion 16 is not particularly limited, but is preferably a shape having an inclined surface such as a hemispherical shape. Thereby, since the front-end | tip part of the insertion direction of the support part 2 which slid inside the groove | channels 14 and 15 can get over the processus | protrusion 16, the hole 61 can be engaged with the processus | protrusion 16 more smoothly. Further, the height of the protrusion is preferably lower than the thickness of the support portion 2.

  Further, the protrusion 16 is preferably located on the front side of the insertion direction into the grooves 14 and 15 of the support portion 2 with respect to the insertion hole 13. Accordingly, it is possible to prevent the protrusion 16 from inhibiting the insertion of the support portion 2 into the grooves 14 and 15 or from requiring an excessive force during the insertion.

[Temporary screw fixing member]
As shown in FIG. 3, the temporary screw fixing member 1 includes a support portion 2 attached to the fixed object 10, a screw holding portion 3 that holds a screw 7 used for screwing, a support portion 2, and a screw holding portion 3. And a connecting portion 4 for connecting the two. The temporary screw fixing member 1 further includes a drop-off preventing means 5 for preventing the screws 7 held by the screw holding part 3 from dropping (falling off) and a positioning means 6 for positioning the support part 2 with respect to the fixed object 10. Have.

  The support part 2, the screw holding part 3, and the connecting part 4 are integrally formed by, for example, processing a thin plate member into a desired shape and bending it at a predetermined location. These constituent materials are not particularly limited, and for example, metal materials such as aluminum and copper, and various resin materials such as polyethylene, polypropylene, polyvinyl chloride, polystyrene, polyamide, and polyimide can be used.

  As described above, the support portion 2 is attached to the fixed object 10 by being inserted into the grooves 14 and 15 formed in the base 12 of the fixed object 10.

  The support portion 2 has a thin plate shape. Moreover, the planar view shape of the support portion 2 is a shape in which adjacent corner portions of a quadrangle (substantially square) are missing. In addition, the planar view shape of the support part 2 is not specifically limited, Circular, a triangle, and a polygon more than a pentagon may be sufficient.

  Moreover, although the thickness of the support part 2 is not specifically limited, It is preferable that it is about 0.3 mm-0.6 mm. By setting it as such thickness, thickness reduction of the support part 2 can be achieved, ensuring the mechanical strength of the support part 2. FIG. Therefore, the screw temporary fixing member 1 can be further reduced in size.

  Further, an insertion hole 21 through which the screw 7 is inserted is formed at the center of the support portion 2. The insertion hole 21 is positioned so as to overlap with the insertion hole 13 formed in the base 12 of the fixed object 10 in a state where the support portion 2 is positioned on the fixed object 10. The shape and size of the insertion hole 21 are not particularly limited as long as the shaft of the screw 7 can pass through, but is preferably a circle slightly larger than the outer diameter of the shaft of the screw 7. Thereby, the screw 7 can be smoothly inserted through the insertion hole 21. Furthermore, it becomes difficult to form a gap between the shaft of the screw 7 and the support portion 2, and the fixed object 10 can be screwed more firmly.

  Here, in the screw temporary fixing member 1, the support portion 2 is inserted into the grooves 14 and 15 from the side opposite to the connecting portion 4. In order to facilitate the insertion of the support portion 2 into the grooves 14 and 15, the distal end portion 22 located on the distal end side in the insertion direction has a shape in which the thickness gradually decreases toward the distal end (edge), specifically, The upper surface of the support portion 2 (the surface on the screw holding portion 3 side) is inclined.

  Such a support portion 2 is provided with positioning means 6 for positioning the support portion 2 with respect to the base 12. Thereby, while the screw temporary fixing member 1 can be reliably located in the predetermined position of the fixed target object 10, the state can be maintained.

  As shown in FIG. 3, the positioning means 6 has a hole (engagement portion) 61 formed in the support portion 2. As shown in FIG. 4, the positioning means 6 is configured so that the hole 61 is engaged with the protrusion 16 formed in the base 12 while the support portion 2 is inserted into the grooves 14 and 15. The support part 2 is positioned. As described above, the insertion hole 21 overlaps the insertion hole 13 in a state where the support portion 2 is positioned.

  By adopting such a configuration for the positioning means 6, the support portion 2 can be positioned with respect to the base 12 with a simple configuration and with certainty. In addition, the positioning means 6 has a concave portion that opens on the lower surface (the surface on the base 12 side) of the support portion 2 instead of the hole as in the present embodiment, and is configured such that the concave portion and the protrusion 16 are engaged with each other. May be.

  The screw holding unit 3 has a function of holding the screw 7. The screw holding portion 3 has a thin plate shape. Further, the screw holding portion 3 is disposed to face the support portion 2 substantially in parallel with a gap.

  The planar view shape of the screw holding portion 3 is not particularly limited, but in the state where the screwing of the fixed object 10 as shown in FIG. 5 is completed (that is, the screw 7 is tightened), the grooves 14 and 15 are formed. A shape that does not contact is preferable. In the present embodiment, the screw holding portion 3 is formed in the grooves 14 and 15 in the state where the screwing of the fixed object 10 is completed by making the shape of the screw holding portion 3 in a plan view substantially smaller than the support portion 2. I try not to touch it. In addition, the planar view shape of the screw holding | maintenance part 3 is not limited to this, For example, a polygon more than circular, a triangle, and a pentagon may be sufficient.

  Moreover, although the thickness of the screw holding part 3 is not specifically limited, It is preferable that it is about 0.3 mm-0.6 mm. Thereby, thickness reduction of the screw holding part 3 can be achieved, ensuring the mechanical strength of the screw holding part 3. FIG. Therefore, the screw temporary fixing member 1 can be further reduced in size.

  As shown in FIG. 3, an insertion hole 31 through which the screw 7 is inserted is formed at the center of the screw holding portion 3. The insertion hole 31 has a circular shape having a diameter slightly larger than the outer diameter of the shaft of the screw 7 and smaller than the outer diameter of the head of the screw 7. The screw holding unit 3 holds the screw 7 by inserting the shaft of the screw 7 through the insertion hole 31. According to such a configuration, the screw 7 is held by the screw holding part 3 simply by inserting the screw 7 into the insertion hole 31, and thus the work for holding the screw 7 in the screw holding part 3 is simplified.

  The distance between the screw holding portion 3 and the support portion 2 is not particularly limited, and can be set as appropriate depending on the length of the shaft of the screw 7 held in the screw holding portion 3, but is slightly smaller than the length of the screw 7 shaft. Is preferably short. As a result, as shown in FIG. 4, the tip of the shaft of the screw 7 can be inserted through the insertion holes 21 and 13 while the screw 7 is held by the screw holding portion 3. For this reason, it is possible to further increase the efficiency of the screwing operation.

  Such a screw holding part 3 is provided with a drop-off preventing means 5 for preventing the screw 7 from dropping off from the screw holding part 3. By having the drop prevention means 5, unintentional drop of the screw 7 from the screw holding portion 3 is prevented, and the working efficiency can be further increased.

  The dropout prevention means 5 has four projecting portions 51 to 54 that project from the side surface of the insertion hole 31 toward the center (center). The four protruding portions 51 to 54 are provided at equal intervals along the circumferential direction of the insertion hole 31. Each of the protruding portions 51 to 54 is formed integrally with the screw holding portion 3. In addition, as a number of protrusion parts, it is not limited to four of this embodiment, 1-3 may be sufficient and five or more may be sufficient. Further, when a plurality of protrusions are provided, the protrusions may be irregularly disposed along the circumferential direction of the insertion hole 31.

  In the drop-off prevention means 5 having such a configuration, the protrusions 51 to 54 enter the screw grooves (between adjacent screw threads) of the screw 7 so that the screw 7 does not easily fall out of the insertion hole 31. Yes. In addition, when the axis | shaft of the screw 7 is arrange | positioned so that it may correspond with the central axis of the penetration hole 31, it is preferable that the front-end | tip of each protrusion part 51-54 is located between the valley bottom of a thread groove, and the top of a screw thread. That is, it is preferable not to contact the valley bottom. Thereby, since the screw 7 and the protrusions 51 to 54 are not completely screwed together, the screw 7 can be easily inserted into the insertion hole 31.

  The connecting part 4 connects the support part 2 and the screw holding part 3. Further, the connecting portion 4 cantilever-supports the screw holding portion 3 with respect to the support portion 2. Specifically, the connecting portion 4 of the present embodiment is formed so as to connect one side of the support portion 2 and one side of the screw holding portion 3. As described above, the screw holding portion 3 is cantilevered with respect to the support portion 2 by the connecting portion 4, whereby the screw temporary fixing member 1 can be further reduced in size.

  The connecting portion 4 is bent toward the outside of the region (space) S between the support portion 2 and the screw holding portion 3 and has a substantially “<” shape. The connecting portion 4 having such a shape is configured to be easily deformed. When the screw holding portion 3 approaches the support portion 2 by tightening the screw 7, the connecting portion 4 is bent and deformed so as to protrude to the outside of the space S. As described above, the connecting portion 4 is easily deformed, so that the fixed object 10 can be screwed with the screw 7 without any trouble.

  When the screw 7 is tightened into the screw hole 201 of the member 20 with a tool such as a screwdriver, the screw holding portion 3 is moved toward the support portion 2 by being pushed by the head of the screw 7, and the tightening of the screw 7 is completed. As shown in FIG. 5, the screw holding portion 3 contacts the support portion 2.

  As shown in FIG. 5, the connecting portion 4 is bent in two at the bent portion 41 by such displacement of the screw holding portion 3, that is, the first portion on the screw holding portion 3 side with respect to the bent portion 41. 42 and the 2nd site | part 43 of the support part 2 side rather than the bending part 41 deform | transform so that it may overlap.

  In the screw temporary fixing member 1 according to the present embodiment, the connecting portion 4 is bent toward the outside of the region S in a natural state, so that the screw holding portion 3 is surely displaced by tightening the screw 7. The connecting portion 4 can be deformed so as to protrude outside the space S. Therefore, since no other members (parts) are interposed between the screw holding part 3 and the support part 2, the screw holding part 3 can be brought into contact (surface contact) with the support part 2 by tightening the screw 7. . As a result, compared with the conventional case where a gap is formed between the screw holding portion 3 and the support portion 2, the fixed object 10 can be screwed with a stronger tightening force.

  Here, the inclinations (angles indicated by θ1 and θ2 in FIG. 4) of the first portion 42 and the second portion 43 with respect to a plane parallel to the support portion 2 and the screw holding portion 3 are not particularly limited, but are 30 ° to The angle is preferably about 70 °, more preferably about 40 ° to 50 °, and further preferably about 45 °. If θ1 and θ2 are less than the above lower limit value, depending on the strength and size (length) of the connecting portion 4, for example, bending may occur at a portion other than the bent portion 41, and the connecting portion 4 is connected as described above. There are cases where it cannot be deformed so that it is folded in two beautifully. On the other hand, if θ1 and θ2 exceed the above upper limit value, the connecting portion 4 may be excessive depending on the size of the temporary screw fixing member 1 and the length of the connecting portion 4 (separation distance between the screw holding portion 3 and the support portion 2). May jump out to the outside of the region S, leading to an increase in the size of the temporary screw fixing member 1. That is, by setting θ1 and θ2 within the above numerical range, the connecting portion 4 can be more reliably deformed into a desired shape while suppressing an increase in the size of the temporary screw fixing member 1.

  Further, as shown in FIGS. 5A and 5B, the connecting portion 4 of the present embodiment has the bent portion 41 at both ends (connecting portion 44 with the screw holding portion 3) in a state where the screwing is completed. And it inclines with respect to the main surface of the support part 2 so that it may be located above the connection part 45) with the support part 2. FIG. By deforming the connecting portion 4 in this way, it is possible to prevent the connecting portion 4 from contacting the base 12 during the deformation. If the connecting portion 4 is deformed so as to be inclined downward, contrary to the present embodiment, the connecting portion 4 comes into contact with the base 12 depending on the strength and size of the connecting portion 4. There is a possibility that the movement of the screw holding portion 3 is restricted, and the screw 7 cannot be tightened smoothly, or the connecting portion 4 is unintentionally damaged.

  In the screw temporary fixing member 1 of the present embodiment, the shape of the connecting portion 4 is designed as follows in order to deform the connecting portion 4 as described above.

  First, the length L1 of the first part 42 closer to the screw holding part 3 than the bent part 41 is designed to be shorter than the length L2 of the second part 43 closer to the support part 2 than the bent part 41. . The difference between L1 and L2 is not particularly limited, but is preferably about the thickness of the support portion 2, for example. Secondly, the connecting portion 44 of the connecting portion 4 with the screw holding portion 3 is designed to be shifted to the inner side of the region S (right side in FIG. 4) than the connecting portion 45 with the support portion 2. The lateral displacement width of the connecting portions 44 and 45 in FIG. 4 is not particularly limited, but is preferably about the thickness of the connecting portion 4, for example. By setting the connecting portion 4 to such a design, it is possible to apply a force that is attracted to the second portion 43 toward the first portion 42 when the connecting portion 4 is deformed. Therefore, the connecting part 4 can be deformed so as to face upward as described above.

  In the present embodiment, the first design item and the second design item are carried out, but it is also possible to carry out only one of the first design item and the second design item. Such an effect can be exhibited.

  Here, by making the difference between L1 and L2 and the shift width of the connecting portions 44 and 45 larger than those described above, the connecting portion 4A is made substantially perpendicular to the base 12 as shown in FIG. It can also be deformed. In this case, the planar space of the temporary screw fixing member 1 after completion of screwing can be reduced.

  The screw temporary fixing member 1 of the first embodiment has been described above, but the screw temporary fixing member in a state where the screw temporary fixing member 1 is mounted on the fixed object 10 and the screw 7 is held by the screw temporary fixing member 1. By distributing as an assembly, the fixed object 10 can be immediately attached at a manufacturing site such as a factory.

Second Embodiment
Next, 2nd Embodiment of the screw temporary fix | stop member of this invention is described.

  FIG. 7 is a perspective view of the temporary screw fixing member according to the second embodiment of the present invention, and FIG. 8 is a cross-sectional view of the temporary screw fixing member in a state where the screw fixing is completed.

  In the following, the second embodiment will be described, but the description will focus on the differences from the first embodiment described above, and description of similar matters will be omitted.

  The screw temporary fixing member 1A of the present embodiment is the same as that of the first embodiment described above except that the shape and physical properties of the connecting portion 4A are different. In addition, the same code | symbol is attached | subjected to the structure similar to 1st Embodiment mentioned above.

  As shown in FIG. 7, the connecting portion 4 </ b> A included in the temporary screw fixing member 1 </ b> A has a shape curved toward the outside of the region S. Further, the connecting portion 4A has a substantially constant curvature radius along the extending direction.

  Such a connecting portion 4A can be elastically deformed. Therefore, as shown in FIG. 8, in the state where the fixing of the fixed object 10 with the screw 7 is completed and the screw holding portion 3 is in contact with the support portion 2, the deformed connecting portion 4 </ b> A has a natural state (screw holding). A force is generated to return to a state in which the portion 3 and the support portion 2 are separated from each other. With such a force, the screw holding portion 3 is pressed against the head of the screw 7 and the support portion 2 is pressed against the base 12. As a result, loosening of the screw 7 can be prevented over time.

  For example, when the screw 7 once tightened is removed, the connecting portion 4A returns to the natural state, and thus the temporary screw fixing member 1A returns to the original shape. Therefore, the screw temporary fixing member 1A of the present embodiment can be reused.

  The constituent material of the connecting portion 4A is not particularly limited as long as it can be elastically deformed.
