Description

  The present invention relates to a cover device that covers and holds a stored item stored in a storage portion, and more particularly to a cover device that includes a plate-shaped resin cover and a metal wire.

  Some recent automobiles have puncture repair kits instead of spare tires. This puncture repair kit is stored in a storage portion formed along, for example, the right wall or the left wall in the trunk, and is taken out and used as necessary. Therefore, it is necessary to provide a cover in the storage portion so that the puncture repair kit does not move during traveling.

  Then, the cover apparatus using metal wires, such as a piano wire, as shown in FIG. 1 was recalled. The cover device includes a cover 100 made of a resin plate having a substantially L-shaped cross section, an engagement plate 200 that engages with an engagement portion of a vehicle body (not shown), and a piano wire 300 that integrally connects the cover 100 and the engagement plate 200. Consists of. The piano wire 300 is bent into a substantially U shape, and includes a pair of leg portions 301 and a bridge portion 302 that connects both ends of the pair of leg portions 301. The bridge portion 302 is integrally fixed to the engagement plate 200. . The pair of leg portions 301 are bent along the surface of the cover 100 and are held by the pair of protrusions 101 along the surface of the cover 100, respectively. And the front-end | tip of a pair of leg part 301 is each bent in the L shape outside, and is pivotally supported by the box member 400 fixed to the vehicle body so that rocking | fluctuation is possible.

  In order to use this cover device, the puncture repair kit 500 is placed in the box member 400, the cover device is swung, and the engagement plate 200 is engaged with the engagement portion of the vehicle body (not shown) from below. Note that a cushion material (not shown) such as a sponge is attached to the back surface of the cover 100. Therefore, the cover 100 presses the upper surface and the front surface of the puncture repair kit 500 through the cushion material, and the puncture repair kit 500 can be stably held. When the puncture repair kit 500 is taken out, if the engagement plate 200 is pressed downward with fingers, the piano wire 300 is elastically deformed to disengage the engagement plate 200 from the engagement portion of the vehicle body (not shown). The puncture repair kit 500 can be taken out by swinging the cover device around the tip of the leg 301.

  In this cover device, the cover 100 has a substantially L-shaped cross section and has two surfaces intersecting each other. Therefore, in order to stably hold the pair of leg portions 301 of the piano wire 300 on the cover 100, protrusions 101 each having an L-shaped cross section are formed on the two surfaces of the cover 100 that intersect each other, and one leg portion 301 is formed. Is held by two protrusions 101. However, since the piano wire 300 is easily elastically deformed, there is a problem that the piano wire 300 is easily detached from the protrusion 101 when assembled.

  On the other hand, Japanese Patent Application Laid-Open No. 2001-138835 describes a structure in which a wire harness is held by protrusions opposite to each other. Therefore, as shown in FIG. 2, it can be considered that the directions of the pair of protrusions are opposite to each other. That is, the protrusion 102 is formed to open on the left side, and the protrusion 103 is formed to open on the right side. By doing so, the movement of the pair of leg portions 301 in the left-right direction is restricted, and the piano wire 300 can be prevented from being detached from the cover 100.

Japanese Patent Laid-Open No. 2001-138835

  By the way, in order to form the protrusion 101 protruding from the cover 100 by mold forming, the cover 100 needs a through hole 104 for mold release regardless of the direction. However, if the protrusions 101 and the through holes 104 are formed on the surfaces of the cover 100 that intersect with each other, the punching directions intersect with each other, resulting in a complicated mold structure and high mold costs. Thus, it has been recalled that the protruding directions of the pair of protrusions 101 from the cover 100 are parallel to each other. In order to do this, a pair of protrusions 101 may be formed close to each other in the length direction of the leg portion 301 at the bent portion where the surfaces intersecting each other of the cover 100 intersect.

  However, when the pair of protrusions 101 are formed close to each other at the bent portion of the cover 100, the portion that holds the leg portion 301 is only the bent portion of the cover 100, so that the cover 100 and the piano wire 300 are held. Since the structure becomes unstable and the length of the unsupported part becomes long and the stress tends to concentrate locally on the piano wire 300, if an excessive load is applied, the piano wire 300 will be permanently deformed. There is a problem that is likely to occur. When the pair of protrusions 101 are close to each other and are opposite to each other, it is not easy to elastically deform and hold the piano wire 300.

  The present invention has been made in view of the above circumstances, avoids an undercut of a through hole for punching for forming a protrusion, and holds a metal wire material on a cover easily and reliably. Preventing the drop-out due to deformation of the wire is an issue to be solved.

A feature of the cover device of the present invention that solves the above problem is that a resin plate-like cover is held in the middle part of the metal wire, and both ends of the metal wire are held on the walls of the storage part, respectively. A cover device for holding a stored item with a metal wire and a cover,
The cover has a guide groove that extends in the length direction of the metal wire and guides the metal wire, and at least a pair of engagements that are spaced apart from each other in the direction in which the metal wire extends to restrict the metal wire from coming out of the guide groove. The nails are integrally formed,
Each of the pair of engaging claws is composed of a foot part standing parallel to each other from the cover and a claw part projecting in opposite directions from the foot part toward the metal wire, and the tip surface being inclined toward the metal wire, and is inserted into the guide groove. The movement of the metal wire rod in the direction away from the surface of the cover is restricted by the claw portions of the pair of engaging claws, and the metal wire rod is sandwiched between the foot portions of the pair of engaging claws to move in the direction along the surface of the cover. The movement is regulated.

  According to the cover device of the present invention, the movement of the metal wire in the upward direction away from the surface of the cover is restricted by the claw portion of the engaging claw, and the upward direction and the axial direction of the metal wire are controlled by the foot portion of the engaging claw. The movement in the right and left direction perpendicular to each other is restricted, and the movement in the downward direction and the left and right direction is restricted by the guide groove, so that the metal wire can be reliably prevented from coming off the cover. In addition, since the movement of the metal wire in the left-right direction can be restricted in a long range by the guide groove, it is possible to prevent local stress concentration on the metal wire. Further, since the pair of engaging claws can be molded close to each other, the through hole for die cutting is prevented from being undercut, and the mold cost is reduced.

It is a principal part expanded sectional view of the cover apparatus which concerns on one Example of this invention.

  The cover device of the present invention has a resin plate-like cover and a metal wire as minimum constituent requirements. Both ends of the metal wire are held on the walls of the storage unit, thereby holding the stored items stored in the storage unit. The shape is not particularly limited, such as a linear shape, an arc shape, an L shape, or a U shape. For example, a linear metal wire can be used, and both ends can be held on the bottom and ceiling of the storage unit. Or you may make it L-shaped, hold | maintain one end in the bottom of a storage part, and hold | maintain the other end part in the side wall of a storage part.

  The metal wire material is used to hold the stored item stored in the storage unit together with the cover, and is required to have rigidity enough to prevent the stored item from dropping off due to deformation. Therefore, the material is preferably spring steel having both elasticity and rigidity, and it is desirable to use piano wire. One or a plurality of metal wires may be used, and the cross-sectional shape may be not only a perfect circle, an ellipse, and an ellipse, but also a quadrangle, a triangle, and the like.

  A cover is hold | maintained at the intermediate part of a metal wire, and covers and holds the storage thing accommodated in the storage part with a metal wire, It is set as the shape bent in flat form, the cross-sectional arc shape, or the cross-section L-shape etc. . The present invention is particularly useful in the case of a cover that has a surface that intersects each other and is bent into a circular arc shape or a L-shaped cross section. In addition, the material will not be restrict | limited especially if it has a rigidity which can mold and can hold a stored item.

  The cover has a guide groove that extends in the length direction of the metal wire and guides the metal wire, and at least a pair of engagements that are spaced apart from each other in the direction in which the metal wire extends to restrict the metal wire from coming out of the guide groove. The nails are integrally formed. It is desirable that the guide groove be formed as long as possible within the length range of the cover. It is desirable that the guide grooves are formed on both sides of the pair of engaging claws, that is, the guide grooves are also formed between the pair of engaging claws.

  The pair of engaging claws are spaced apart from each other in the extending direction of the metal wire, and each includes a foot portion that rises in parallel with each other from the cover, and a claw portion that is formed at the tip of the foot portion. A pair of nail | claw part protrudes in the mutually reverse direction toward a metal wire from a foot | leg part. In other words, the pair of legs are formed on the left and right sides of the metal wire so as to sandwich the metal wire, and the pair of claws protrude inward toward the metal wire in opposite directions. Therefore, the metal wire held by the pair of engaging claws is sandwiched between the legs of the pair of engaging claws, so that the movement in the left-right direction perpendicular to the axial direction of the metal wire is restricted along the surface of the cover. The movement in the direction away from the surface of the cover is restricted by the claw portions of the pair of engaging claws.

  In addition, the claw portions of the pair of engaging claws are each inclined at the tip surface toward the metal wire. Therefore, when the metal wire is attached to the cover, when the metal wire is pressed toward the tip surface of the claw portion, the force elastically deforms the pair of engaging claw feet away from each other. The metal wire can be engaged and held by the pair of engaging claws by restoring the foot portion to the original shape by the elastic reaction force after getting over the portion. Then, by forming the guide groove on the extended line connecting the claw portions of the pair of engaging claws, the holding on the engaging claw and the arrangement in the guide groove can be performed simultaneously.

  In order to integrally form the pair of engaging claws with the cover, a through hole for punching is required on the surface of the cover facing the claw portion. In the cover device of the present invention, since the foot portions of the pair of engaging claws stand up from each other in parallel, the extending directions of the through holes are also parallel to each other, and the undercut does not occur, thereby simplifying the mold structure. Can do. For example, when the cover is bent, such as an L-shaped cross section, the pair of engaging claws and the through hole are formed close to each other at the bent portion. By doing in this way, a pair of legs and a pair of penetration holes can be formed in parallel mutually, respectively.

  It is desirable that the overlap between the claw portion of the engaging claw and the metal wire is not less than a half width and not more than the full width of the metal wire. If the claw part is formed so as to exceed the full width, it is difficult to fit the metal wire if the metal wire is less than half width and the claw part is easily removed from the claw part.

  Hereinafter, the present invention will be described specifically by way of examples.

  FIG. 3 is an overall perspective view of the cover device of this embodiment. The cover device includes a cover 1 made of a resin plate, a resin engagement plate 2 that engages with an engagement portion of a vehicle body (not shown), and a piano wire 3 that connects the cover 1 and the engagement plate 2 together. The piano wire 3 is bent into a substantially U shape, and includes a pair of leg portions 30 and a bridge portion 31 that connects both ends of the pair of leg portions 30, and the bridge portion 31 is integrally fixed to the engagement plate 2. . The pair of leg portions 30 are bent along the surface of the cover 1, and the ends of the pair of leg portions 30 are bent in an L shape and are held swingably by a box member 4 fixed to the vehicle body. ing.

  The cover 1 is formed in a substantially L-shaped cross section, and has surfaces A and B intersecting each other and a bent surface C between the surface A and the surface B. A pair of routing portions 10 having a substantially M-shaped cross section are formed on the surface A, the bent surface C, and the surface B, and a pair of leg portions 30 of the piano wire 3 are routed to the pair of routing portions 10, respectively. ing. A cushion material (not shown) made of urethane sponge is attached to the back surface of the cover 1 in advance.

  As shown in an enlarged view in FIGS. 4 and 5, a first engagement claw 11 facing outward and a guide groove 12 having a semicircular cross section are provided at positions corresponding to the curved surface C of the pair of routing portions 10. A guide plate 13 and a second engagement claw 14 directed inward are formed. Further, a guide groove 15 having a semicircular cross section is formed which is bent after being along the bent surface C adjacent to the first engaging claw 11 and extending to the end surface of the cover 1 along the surface B, and adjacent to the second engaging claw 14. A guide groove 16 having a semicircular cross section is formed which is bent along the bent surface C and extends along the surface A to the end surface of the cover 1.

  As shown in FIG. 6, the first engaging claw 11 includes a plate-like foot portion 110 protruding from the bottom surface of the routing portion 10 and a claw portion 111 protruding inward from the tip of the foot portion 110. It is configured. At the base of the foot part 110, a die-cutting through hole 112 that penetrates the bottom part of the routing part 10 is formed. A tapered surface 113 is formed at the tip of the claw portion 111 so as to decrease in thickness toward the inside. Further, the lower surface of the claw portion 111 opposite to the tapered surface 113 has a circular arc shape along the surface of the leg portion 30 of the piano wire 3. The overlap between the claw portion 111 and the leg portion 30 is greater than or equal to the radius of the leg portion 30 and less than the diameter.

  The second engagement claw 14 is formed on the opposite side of the first engagement claw 11 with respect to the guide plate 13 in the axial direction of the leg portion 30 of the piano wire 3. Since the second engaging claw 14 has the same shape as the first engaging claw 11, a detailed description thereof is omitted, but the position of the foot 140 is located on the leg 30 of the piano wire 3 as shown in FIG. On the other hand, the claw portion 141 is on the opposite side to the foot portion 110 of the first engagement claw 11, and the claw portion 141 extends in a direction opposite to the claw portion 111 of the first engagement claw 11 with respect to the leg portion 30 of the piano wire 3. At the base of the foot part 140, a through hole (not shown) for punching that penetrates the bottom part of the routing part 10 is formed.

  4 and 7, the guide groove 15, the claw portion 111 of the first engagement claw 11, the guide groove 12, the claw portion 141 of the second engagement claw 14, and the guide groove 16 are bent from the surface B. They are arranged in this order on a straight line through the surface C and toward the surface A.

  In order to assemble the cover device of the present embodiment configured as described above, first, a piano wire 3 having the engagement plate 2 fixed to the bridge portion 31 is prepared in advance, and the bent portions of the pair of leg portions 30 are bent surfaces. Along the routing portion 10 at the position C, the pressure is pushed into the routing portion 10. Then, the leg portion 30 comes into contact with the tapered surfaces 113 of the claw portions 111 and 141 of the first engagement claw 11 and the second engagement claw 14, and the second engagement with the foot portion 110 of the first engagement claw 11 by the pressing force. The foot 140 of the claw 14 is elastically deformed, and both the claw 111 and the claw 141 move away from the leg 30. When the leg 30 gets over the claw part 111 and the claw part 141, the foot part 110 and the foot part 140 are restored to the original shape by the elastic reaction force, and the leg part 30 is held below the claw part 111 and the claw part 141. Is done. At the same time, the foot 30 is disposed in the guide groove 12, the guide groove 15, and the guide groove 16.

  On the other hand, a box member 4 is fixed to a storage portion formed on the trunk side wall of the vehicle, and a puncture repair kit is stored in the box member 4. In the piano wire 3 in which the cover 1 and the engagement plate 2 are held and fixed as described above, both ends of the leg portion 30 are swingably held by the box member 4. Then, by engaging and holding the engagement plate 2 with the engagement portion of the vehicle body (not shown), the cover 1 comes into contact with the puncture repair kit box via a cushion material (not shown) and covers and holds the puncture repair kit together with the piano wire 3. be able to.

  According to the cover device of this embodiment, the piano wire 3 is restricted from moving upward from the surface of the cover 100 by the claw portion 111 of the first engagement claw 11 and the claw portion 141 of the second engagement claw 14. The movement of the piano wire 3 in the horizontal direction perpendicular to the axial direction of the piano wire 3 is restricted along the surface of the cover 1 by the foot 110 and the foot 140, and in the downward direction and the horizontal direction by the guide grooves 15, 12, and 16. Therefore, the piano wire 3 can be reliably prevented from coming off the cover 1. Moreover, since the movement in the left-right direction is restricted by the guide grooves 15 and 16 in a long range, it is possible to prevent the stress of the piano wire 3 from being concentrated locally. Furthermore, since the foot portions 110 and 140 and the through hole extend in parallel with each other, the die cutting through hole is not undercut, and the mold cost can be reduced.

  In the above-described embodiment, a piano wire having a perfect cross section is used as the metal wire. However, the present invention is not limited to this, and a plate-like metal wire having a rectangular cross section may be used. In the above embodiment, the pair of leg portions of the piano wire is held by the cover. However, if the leg portion has a sufficient thickness or width, one leg portion can be held by the cover. Depending on the shape of the cover, the distance between the first engaging claw 11 and the second engaging claw 14 can be increased. In this case, it is preferable to increase the length of the guide plate 13 in the axial direction of the leg 30.

  Since the cover device of the present invention is lightweight and inexpensive, it can be used to hold various articles detachably.
