Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a structure for attaching a guide rail of a vehicle ashtray provided in the interior of a vehicle to an outer case.

[Prior Art] As shown in FIGS. 10 to 14, a conventional vehicular ashtray is mounted on an instrument panel 1 of a vehicle.
Or outer case 2 attached to the cluster
, a guide rail 3 attached to a side wall 2a of the outer case 2, and an inner case 5 having a rotatable protector 4 biased upward.

The guide rail 3 is usually made of resin, and is attached to the side wall 2a of the outer case 2 as shown in FIGS. 10, 12, and 14.
As shown in the figure, the heat caulking boss 6 formed on the guide rail 3 is inserted into the hole 7 of the outer case side wall 2a.
The boss 6 is inserted into the hole and fixed by hot caulking, or it is fixed by a snap fit as shown in FIG. 13.

[Problem to be solved by the invention] For this reason, a space in the width direction of the ashtray is required for the heat caulking of the boss 6 (distance d in Fig. 14).
Another problem is that a space corresponding to the protrusion of the snap fitting claw (distance d' in FIG. 13) is required, and the width of the ashtray is reduced accordingly.

In addition, the ceiling wall 2b of the outer case 2 has a concave surface close to the side wall 2a of the outer case 2, which normally functions as a tightening seat 8 for fixing the outer case 2 to the instrument panel 1 or the cluster. As shown in FIG. 11, the guide rail 3 cannot be installed directly from the side, and the guide rail 3 must be rotated to approach the outer case side wall 2a, making it difficult to fit the guide rail 3 into the outer case 2. There was a problem.

In addition, as shown in FIG. 13, the snap-fit needs to have a claw 9 that can be elastically displaced up and down to function as the boss 6, so a hole 10 for forming the claw 9 is formed in the guide rail 3, and the ashtray There was a problem that the airtightness of the tube deteriorated.

In order to alleviate the above-mentioned problems, the present invention suppresses the reduction of the mounting dimension to the vehicle in the width direction of the ashtray, and allows the guide rail to be easily mounted to the outer case even though there is a concave surface on the outer case ceiling wall. It is an object of the present invention to provide a guide rail mounting structure for a vehicle ashtray in which the ashtray is sealed well in combination with an outer case and a guide rail.

[Means for Solving the Problems] The guide rail mounting structure for a vehicle ashtray of the present invention that meets this objective includes mounting a guide rail along the side walls of an outer case having a ceiling wall, a side wall, and a back wall. , in a vehicle ashtray in which the inner case is brought into sliding contact with the guide rail and the inner case is taken in and out of the outer case, a notch is provided at an angle with the side wall of the rear wall of the outer case, and a claw engaging means is provided on the side wall of the outer case. A cut-out is formed downwardly at the front part of the outer case ceiling wall in the ashtray width direction on both sides in the ashtray width direction, and a cutout is formed at the front end of the guide rail in the ashtray width direction at the center A stopper extending toward the outer case is integrally formed with the guide rail, and a slope is formed at the base of the stopper to engage with the cut-out and press the guide rail against the side wall of the outer case, so that the guide rail is elastically displaced in the width direction of the ashtray. the guide rail, the rear end of the guide rail in the direction of insertion and removal of the inner case is inserted into the notch of the outer case, the pawl is engaged with the pawl engaging means on the side wall of the outer case, and the stopper is engaged. is attached to the outer case in a state where it is brought into contact with the cut and raised part of the outer case.

[Function] In the vehicle ashtray having the above structure, the guide rail can be held down in the width direction of the ashtray by inserting the guide rail into the notch at the rear of the outer case at the rear end and by cutting and raising the outer case at the front end. There is no need to prevent the ashtray from coming off in the width direction, and the claws only need to function on the side wall of the outer case to prevent it from coming off in the forward direction, reducing the amount of protrusion from the side of the outer case. Can be large in relation to panels or clusters.

Furthermore, the guide rail can be inserted from the front surface of the outer case, and the difficulty of fitting the guide rail into the outer case due to the recessed portion on the upper surface of the outer case is eliminated.

It is inserted into the notch 20 of the outer case 11 and fixes the rear end of the guide rail 12 in the width direction of the ashtray.

Stopper 1 integrally formed on guide rail 12
At the corner of 6, a protrusion having a first slope 22 and a second slope 23 is formed at the base of the protector guide 15. The first slope 22 is
It is located at the center of the protrusion in the width direction of the ashtray, is inclined from the lower end of the protector guide 15 toward the upper end, and extends toward the center in the width direction of the ashtray, and engages with the cutout 18 of the outer case 11. Then, the guide rail 12 is pressed toward the side wall 11b and ceiling wall 11a of the outer case 11. Second slope 23
is located at the rear end of the protrusion in the direction in which the inner case 14 is pulled out, and consists of a triangular slope extending from one point of the lower end of the protector guide 15 to the upper end of the first inclined surface 22 and the upper end of the protector guide 15; The outer case side wall 11b of the guide rail 12 engages with the cut-and-raised part 18 of the case 11.
When inserted into the housing, the guide rail 12 is pressed toward the outer case side wall 11b and the ceiling wall 11a, and the transition of the cut and raised portion 18 to engagement with the first slope 22 is made smooth. In this way, the guide rail 12 has its front end cut and raised and engages with the 18.
By engaging the rear end with the notch 20, it is fixed in the width direction of the ashtray.

On the back wall 12c of the guide rail 12, the back wall 12
An elastic arm 25 is provided by forming a U-shaped slit 24 in c, and a claw 26 that projects toward the back side of the U-shape of the guide rail 12 is formed at the tip of the elastic arm 25. There is. on the other hand,

A protector 13 is installed near the upper end of the inner case 14 on the back side of the side walls 14b, 14c.
It is rotatably supported with respect to 4. The protector 13 has a rear end pivoted to the inner case 14, a front end extending to the center of the inner case 14 in the front-rear direction, and extends across the entire width of the inner case 14 in the width direction. The protector 13 is always urged upward by a spring (not shown) so that the front end thereof springs upward.

Protector 13 usually consists of a piece of metal. Near both widthwise ends of the rear end of the protector 13, there are cut-outs 1 of the outer case 11 when inserting and removing the inner case 14.
8 and the stopper 16 (however, in a position that does not interfere with the protector guide 19).
A protector stopper 17 as shown in FIG. 1 is formed. The protector stoppers 17 are formed small on both sides of the rear end of the protector 13 by cutting and raising the wall of the protector 13 upward. Of the both ends of the protector 13 in the width direction, the upper surface of the portion further outward in the width direction by the protector stopper 17 is attached to the protector guide 19 on the outer case 11 side when the inner case 14 is inserted or removed.
This is the part that comes into sliding contact with the

Next, the operation in the first embodiment will be explained. 3 to 5 show the order in which the guide rail 12 is attached to the outer case 11.

As shown in FIG. 3, the guide rail 12 is inserted from the front end of the outer case 11 toward the rear end along the outer case side wall 11b. Claw 26
When the portion of the guide rail 12 comes into sliding contact with the outer case side wall 11b, the elastic arm 25 is elastically deformed toward the center in the ashtray width direction, and the claw 26 is elastically displaced toward the center in the ashtray width direction. It can be slid into the case 11.

As the guide rail 12 is further inserted,
As shown in FIG. 4, the extending portion 21 at the rear end of the guide rail 12 is inserted into the notch 20 at the rear end corner of the outer case 11. As shown in FIG. Outer case 11
The downward cut-and-raise 18 is the second part of the guide rail 12.
The guide rail 12 is pressed against the outer case side wall 11b and the ceiling wall 11a, and also helps in sliding contact with the first slope 22.

When the guide rail 12 is pushed to the insertion end position, as shown in FIG. 5, the claw 26 restores its elastic displacement and enters the hole 27 in the outer case side wall 11b, fixing the guide rail 12 in the ashtray longitudinal direction. . At this time, the outer case 11 is cut and raised 18
is engaged with the first slope 22 of the guide rail 12, and as shown in FIG.
A force F ₁ that presses against the outer case side wall 11b and a force F ₂ that presses against the ceiling wall 11a are applied to press the guide rail 12 against the outer case 11 and suppress the drooping of the guide rail 12.
In addition, the rear end of the guide rail 12 and the outer case 1
1 and the rear wall 11d, the difference in thermal expansion between the guide rail 12 and the outer case 11 can be absorbed without difficulty.

7 to 9 show a second embodiment of the present invention. In the second embodiment, the structure of the elastically displaceable pawl is different. As shown in the figure, an elastically displaceable pawl 26' is attached to the end of an elastic arm 25' formed by a slit 24' at the rear of the rear end extension 21' of the guide rail 12'. The claw 2 is formed to protrude outward in the direction.
6' is elastically displaced in the width direction of the ashtray by elastic deformation of the elastic arm 25'. The claw 26' is the outer case 1
The guide rail 12' is restrained from moving in the forward direction of the ashtray by engaging with the rear end of the side wall 11b' of the ashtray as a claw engaging means. in this case,
There is no need to provide holes as claw engaging means in the outer case side wall 11b'. Other configurations and operations are similar to those of the first embodiment.

[Effects of the Invention] The following various effects can be obtained by using the guide rail mounting structure for a vehicle ashtray of the present invention.

(a) The guide rail is secured to the outer case in the width direction of the ashtray by a notch at the rear end corner of the outer case and a cut-and-raised cut at the front end of the outer case, and the claw and outer case are elastically displaceable in the front and back direction of the ashtray. Fixation is achieved by engagement with the claw engaging means formed on the side wall (the hole in the first embodiment, the rear end of the extension part in the second embodiment), which is necessary for conventional heat caulking of the claws. This eliminates the need for a large space in the width direction of the ashtray, allowing the ashtray to be expanded to fill the ashtray installation space of the instrument panel or cluster, and the width dimension of the ashtray to be made larger than in the past.

(b) In addition, since the guide rail is attached to the outer case by sliding it into contact with the side wall of the outer case and pushing it in, even if there is a concave surface on the ceiling wall of the outer case, it can be installed without being interfered with. Guide rail installation work becomes easier. Furthermore, since the snap fit uses elastically displaceable pawls, there is no need for heat caulking as in the past for fixing, which also facilitates the work.

(c) Furthermore, the holes formed in the guide rail or the holes formed in the outer case are covered by the outer case or the guide rail, improving the sealing performance of the ashtray.

(d) By providing a gap between the rear end of the guide rail and the back wall of the outer case, deformation of the guide rail due to thermal expansion can be eliminated.
