DETAILED DESCRIPTION OF THE INVENTION
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to a preferred embodiment. A glove box that is pivotally supported on an instrument panel of an automobile as a support structure is also supported by the switchgear according to the embodiment. The glove box was basically developed by connecting one end of the string body, which was elastically urged in the pull-back direction of the air damper, to the side of the glove box as in the conventional case. The air damper controls the opening and closing movement.
[0011]
In the present embodiment, on the premise of such a configuration, the boss 1 having the large-diameter flange portion 1a is integrally formed on the side surface of the glove box B as shown in FIGS. A pair of rotation stopper walls 2 are provided so as to stand and extend parallel to the outer peripheral surface of the boss 1. In the figure, reference numeral 3 designates a pin provided adjacent to the boss 1 for regulating the fully open position of the glove box B.
[0012]
Further, as shown in FIG. 1, a clip 11 having a semi-cylindrical shape is provided on one end portion 22a of the string 22 of the air damper A, and the clip 11 is arranged as shown in FIG. A first receiving portion 12 and a second receiving portion 13 that communicate with each other across a horizontal U-shaped partition wall 14 are defined, and the large-diameter flange portion 1a of the boss 1 is defined as the first receiving portion 12. Receiving the boss 1 body into the second receiving portion 13, and opening the first receiving portion 12 and the second receiving portion 13 of the clip 11 on the retracting direction side of the string body 22, The guide surfaces 15 that widen in the opening direction are formed at both end edges of the partition wall 14 that divides the first receiving portion 13 and the second receiving portion 13, and the one end portion 22 a of the string 22 is rotatable on the head side of the clip 11. It is the structure which forms the support part 16 to support.
[0013]
As shown in FIG. 4, the air damper A itself moves in the cylinder 21 by connecting the cylinder 21 fixed to the instrument panel (not shown) side and the other end 22 b of the string body 22. A piston 23, a guide cap 24 that guides the movement of the string 22 on one end opening side of the cylinder 21, and an end cap 27 with a valve 26 that opens and closes a communication hole 25 formed in the other end opening of the cylinder 21. And a compression coil spring 28 interposed between the guide cap 24 and the piston 23 in the cylinder 21, and the string 22 connected to the piston 23 is the cylinder pressure by the spring pressure of the compression coil spring 28. The bullet is energized so as to be pulled back into the interior of 21.
[0014]
Therefore, when the one end portion 22a of the string body 22 that is elastically biased in the pull-back direction of the air damper A is connected to the side surface of the glove box B, the clip 11 is connected to the string body as shown in FIG. As shown in FIG. 6, the guide surface 15 is guided while being pulled against the bullet urging force of 22 and applied to the boss 1, and the flange portion 1 a of the boss 1 is received in the first receiving portion 12 of the clip 11. In addition, it is possible to connect the one end portion 22a of the string body 22 to the side surface of the glove box B almost automatically just by receiving the boss 1 body in the second receiving portion 13, In comparison, the assembly workability can be greatly improved. In such a work, it is possible to attach the glove box B after attaching the air damper A to the instrument panel side.
[0015]
In such a state, as shown in the drawing, the pair of rotation stopper walls 2 extending on the outer peripheral surface of the boss 1 are in pressure contact with the U-shaped inner surface of the partition wall 14 of the clip 11, respectively. Since it will be located inside the receiving part 13, the relationship between the glove box B and the clip 11 is fixed, so that both B and 11 do not rattle and the flange part 1 a of the boss 1 is partitioned. Since the first receiving portion 12 is received through the wall 14, the clip 11 itself never comes off the boss 1.
[0016]
Accordingly, when the glove box B is rotated in the opening direction in a state where the clip 11 is fixed to the boss 1, the string body 22 is gradually pulled out from the cylinder 21, and the piston 23 is brought to the spring pressure of the compression coil spring 28. As a result, the glove box B slowly rotates to the open state by the flow resistance of air passing through an orifice (not shown) provided on the piston 23 side. Guaranteed.
[0017]
In this case, since the opening of the first receiving portion 12 and the second receiving portion 13 exists on the side of the string body 22 in the retracting direction, the boss 1 and the clip are moved in the process of moving the glove box B. 11 and the end portion 22a of the string body 22 is rotatably supported by the support portion 16 of the clip 11 with its annular shape, so that the glove box B rotates. Even in this case, excessive friction does not occur with the clip 11.
[0018]
On the other hand, when the glove box B is rotated in the closing direction, the piston 23 is forcibly pushed back in the cylinder 21 by the spring pressure of the compression coil spring 28 together with the string body 22, Since the air accumulated in 21 is released from the end cap 27 side to the outside through the communication hole 25 opened by the valve 26, the piston 23 quickly moves in the cylinder 21 to facilitate the closing operation of the glove box. In this case as well, in the process in which the glove box B is rotated with the opening of the first receiving portion 12 and the second receiving portion 13 existing on the retracting direction side of the string 22, the boss 1 and the clip 11 never come off.
[0019]
【The invention's effect】
As described above, the present invention uses only the boss standing on the box body side and the one clip provided on one end of the string body by adopting the above configuration, so that the number of parts can be reduced. Therefore, when the device itself is simplified and the one end of the string body is connected to the box body, the clip is pulled against the elastic urging force of the string body and applied to the boss, By only receiving the flange portion of the boss in one receiving portion and receiving the boss main body in the second receiving portion, it becomes possible to connect the one end portion of the string body to the box body side almost automatically.
