Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.
Example 1
First, Example 1 of the present invention will be described with reference to FIGS. First, with reference to FIGS. 1-4, it demonstrates from the whole structure of the cushion clip 1 which concerns on Example 1. FIG. The cushion clip 1 mainly includes a base 2, a compression spring 3, a shaft 4, and a bezel 5. Below, among these, the base 2, the shaft 4, and the bezel 5 are demonstrated separately. In addition, since the compression spring 3 may be a general-purpose thing, the detailed description is abbreviate | omitted.

  First, the base 2 will be described. The base 2 is composed of a cylindrical member having an opening 20 formed on one side and a bottom wall 22 formed on the other side. A cross-shaped rib 22a into which one side of the compression spring 3 can be inserted is formed on the bottom wall 22 so as to protrude inward. A guide hole 24 that can guide a stopper 46 of the shaft 4 to be described later is formed on the outer peripheral surface of the base 2 so as to extend along the axial direction of the base 2. Three guide holes 24 are formed so as to be even in the circumferential direction of the base 2.

  Further, a cutout 26 cut out from the edge of the opening 20 is formed on the outer peripheral surface of the base 2. The notches 26 are also formed at three locations so as to be even in the circumferential direction of the base 2. Thereby, the engaging claw 54 of the bezel 5 to be described later can be bent. Further, an engaging claw 28 that can be assembled in an engaging hole 56 of the bezel 5 described later is formed on the outer peripheral surface of the base 2. The engaging claws 28 are also formed at three locations so as to be even in the circumferential direction of the base 2. The base 2 is integrally formed from a hard resin material.

  Next, the shaft 4 will be described. The shaft 4 has an opening 40 formed on one side and a ceiling wall 42 formed on the other side, and is configured by a cylindrical member that can be inserted into the base 2 in the opening 40 side. . The surface of the top wall 42 is covered with an elastomer 44 (soft resin material). Thereby, the prevention effect of the hitting sound produced when closing the grab door 80 mentioned later can be heightened.

  A stopper 46 that can be guided in the guide hole 24 of the base 2 is formed on the outer peripheral surface of the shaft 4. The stoppers 46 are formed at three locations so as to correspond to the three guide holes 24, respectively. The shaft 4 has a step 48 formed in the axial direction of the shaft 4 so that the top wall 42 side is thinner than the opening 40 side. Thereby, when the cushion clip 1 is assembled, the step 48 is caught on the edge of the opening 50 of the bezel 5, so that the shaft 4 jumps out of the base 2 even if the stopper 46 of the shaft 4 falls off from the guide hole 24 of the base 2. Can be prevented. The shaft 4 is integrally molded (two-color molding) from a hard resin material and an elastomer 44 (soft resin material).

  Finally, the bezel 5 will be described. The bezel 5 is composed of a cylindrical member having an opening 50 formed on one side and an opening 52 formed on the other side. A flange 50 a is formed at the edge of the opening 50. On the outer peripheral surface of the bezel 5, an engaging claw 54 that can be assembled in a mounting hole 72 of an instrument panel 70 described later is formed. The engaging claws 54 are formed at three locations so as to be even in the circumferential direction of the bezel 5.

  The bezel 5 can be attached to the instrument panel 70 by sandwiching the edge of the mounting hole 72 of the instrument panel 70 described later between the flange 50a and the three engaging claws 54. A cushion clip 1 can be attached. Further, an engagement hole 56 in which the above-described engagement claw 28 of the base 2 can be assembled is formed on the outer peripheral surface of the bezel 5. The engagement holes 56 are formed at three locations so as to correspond to the three engagement claws 28 respectively. The bezel 5 is also integrally formed from a hard resin material.

  Next, a procedure for assembling the cushion clip 1 composed of the base 2, the compression spring 3, the shaft 4, and the bezel 5 described above will be described. First, an operation of inserting one side of the compression spring 3 into the rib 22a of the base 2 is performed. Next, the operation of assembling the shaft 4 into the base 2 is performed so that the other side of the compression spring 3 is inserted into the shaft 4.

  At this time, an operation of fitting (assembling) the stopper 46 of the shaft 4 into the guide hole 24 of the base 2 is also performed. This fitting is performed at three places simultaneously. Thereby, the shaft 4 can be assembled | attached so that it can advance / retreat with respect to the base 2 in the state biased to the advance direction. Finally, the operation of assembling the engaging claws 28 of the base 2 into the engaging holes 56 of the bezel 5 is performed. This assembly is also performed at three locations simultaneously. In this way, the cushion clip 1 is assembled.

  Then, with reference to FIGS. 5-6, the effect | action of the cushion clip 1 mentioned above is demonstrated. In this description, an example in which the cushion clip 1 is applied to the glove box 60 will be described. The glove box 60 is a well-known one and includes a box 76 formed in the instrument panel 70 through an opening 74 and a grab door 80 hinged to the instrument panel 70 so as to be able to close the box 76. Yes. The instrument panel 70 corresponds to a “fixing member” recited in the claims. The grab door 80 corresponds to a “movable member” recited in the claims.

  At the upper edge of the opening 74 of the instrument panel 70, a mounting hole 72 is formed in which the engaging claw 54 of the bezel 5 of the cushion clip 1 can be assembled. Therefore, as shown in FIG. 5, the cushion clip 1 can be attached to the instrument panel 70. When the grab door 80 is closed from this mounted state, the shaft 4 is pressed from the inner surface of the grab door 80.

  Then, the shaft 4 enters the base 2 against the urging force of the compression spring 3. Thereby, the hitting sound produced when the grab door 80 is closed can be prevented as in the prior art. Eventually, as shown in FIG. 6, the grab door 80 is locked in a closed state (locked by a lock mechanism (not shown)), so that the shaft 4 is held in the base 2.

  As a result, the urging force of the compression spring 3 acts on the grab door 80. Therefore, as in the prior art, rattling against the instrument panel 70 when the grab door 80 is locked in the closed state can be prevented by the reaction force acting on the grab door 80 from the bent compression spring 3 via the shaft 4. .

  The cushion clip 1 according to the first embodiment of the present invention is configured as described above. According to this configuration, the generation source of the elastic force of the cushion clip 1 is the compression spring 3. Therefore, even if the usage environment of the cushion clip 1 changes, the fall of the elasticity can be suppressed.

(Example 2)
Next, Example 2 of the present invention will be described with reference to FIGS. In the following description, the same members as those in the first embodiment are denoted by the same reference numerals in the drawings, and redundant description will be omitted.

  First, the overall configuration of the cushion clip 101 according to the second embodiment will be described with reference to FIGS. The cushion clip 101 mainly includes a base 102, a compression spring 103, and a shaft 104. Below, among these, the base 102 and the shaft 104 will be described individually. The compression spring 103 may be a general-purpose one, and a detailed description thereof will be omitted.

  First, the base 102 will be described. The base 102 is composed of a cylindrical member having an opening 120 formed on one side and a bottom wall 122 formed on the other side. A flange 120 a is formed at the edge of the opening 120. On the outer peripheral surface of the base 102, an engaging claw 124 that can be assembled in the mounting hole 72 of the instrument panel 70 is formed. The engaging claws 124 are formed at three locations so as to be even in the circumferential direction of the base 102.

  The base 102 can be attached to the instrument panel 70 by sandwiching the edge of the mounting hole 72 of the instrument panel 70 described later between the flange 120a and the three engaging claws 124. A cushion clip 101 can be attached. On the other hand, the bottom wall 122 is formed with an insertion hole 122a into which a stopper 142 of the shaft 104 described later can be inserted. The base 102 is integrally formed from a hard resin material.

  Next, the shaft 104 will be described. The shaft 104 includes a shaft member having a receiving portion 140 having a diameter larger than the shaft diameter of the shaft 104 on one side and a stopper 142 on the other side. The surface of the receiving portion 140 is covered with an elastomer 144 (soft resin material). Thereby, the prevention effect of the hitting sound produced when closing the grab door 80 mentioned later can be heightened. The shaft 104 is integrally molded (two-color molding) from a hard resin material and an elastomer 144 (soft resin material).

  Next, a procedure for assembling the cushion clip 101 including the above-described base 102, compression spring 103, and shaft 104 will be described. First, the operation of inserting the shaft 104 into all of the compression springs 103 is performed. Next, the stopper 142 of the shaft 104 is inserted (assembled) into the insertion hole 122a of the base 102 in the inserted state. Thus, the shaft 104 can be assembled so as to be able to advance and retract with respect to the base 102 while being urged in the advance direction. In this way, the cushion clip 101 is assembled.

  Then, with reference to FIGS. 11-12, the effect | action of the cushion clip 101 mentioned above is demonstrated. In this description, as in the first embodiment, an example in which the cushion clip 101 is applied to the glove box 60 will be described. As shown in FIG. 11, a cushion clip 101 is attached to the instrument panel 70. When the grab door 80 is closed from this mounted state, the shaft 104 is pressed from the inner surface of the grab door 80.

  Then, the shaft 104 enters the base 102 against the urging force of the compression spring 103. Thereby, the hitting sound produced when the grab door 80 is closed can be prevented as in the prior art. Eventually, as shown in FIG. 12, the grab door 80 is locked in a closed state (locked by a lock mechanism not shown), so that the shaft 104 is held in the base 102.

  As a result, the urging force of the compression spring 103 acts on the grab door 80. Therefore, as in the prior art, rattling against the instrument panel 70 when the grab door 80 is locked in the closed state can be prevented by a reaction force acting on the grab door 80 from the bent compression spring 103 via the shaft 104. .

  The cushion clip 101 according to the second embodiment of the present invention is configured as described above. According to this configuration, similarly to the cushion clip 1 of the first embodiment, even if the usage environment of the cushion clip 101 changes, it is possible to suppress a decrease in the elasticity. Further, according to this configuration, the shaft 104 is inserted into the entire compression spring 103. Therefore, when the shaft 104 is pressed from the inner surface of the grab door 80, the compression spring 103 can be prevented from buckling. Therefore, the elastic force by the compression spring 103 can be sufficiently generated.

The contents described above are only related to one embodiment of the present invention, and do not mean that the present invention is limited to the above contents.
In the first embodiment, the configuration in which the cushion clip 1 is mounted on the instrument panel 70 has been described. However, the present invention is not limited to this, and the cushion clip 1 may be attached to the grab door 80. The same applies to the second embodiment.
