Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a rail structure of a vehicle ashtray provided in the passenger compartment of a vehicle.

[Prior Art] As shown in FIG. 8, a vehicle ashtray conventionally has a rail 51 having a U-shaped cross section fixed to the side wall of a retainer 50, and an engaging portion 53 of a box 52 that engages with the rail. By slidably engaging the box 52, the box 52 can be moved in and out of the retainer 50. Then, the rail 51 or the engaging portion 5
A spring support hole 54 is formed in either one of the boxes 3 and 3, and a spring 55 made of, for example, a plate spring shape is housed in the spring support hole 54 to apply an appropriate frictional force to the movement of the box. was.

[Problems to be solved by the invention] However, in the conventional vehicle ashtray described above, the spring 55 is made of metal, and the engaging portion 53
Because it was made of resin, it had poor wear resistance, and
There was a problem in that the sliding properties were poor and the operation of the box appearing and retracting was not smooth, and the sliding surface needed to be greased.

In order to alleviate such problems, the
Publication No. 66038 discloses a spring made of resin, but there is a problem with the durability of the spring, and Publication No. 1186/1986 discloses a method in which the spring is coated with resin and then assembled into a retainer. However, there were problems with the manufacturability of the coating and the ease of assembling the spring to the retainer.

In order to alleviate such problems, this invention
To provide a rail structure for a vehicle ashtray that has good abrasion resistance, has a good feeling of operation, does not require the application of grease, and is easy to assemble.

[Means for Solving the Problems] The rail structure of the vehicle ashtray of the present invention, which meets this objective, has a rail fixed to a retainer, and an engaging portion of the box that engages with the rail in a slidable manner. A vehicle in which the box is movable in and out of the retainer, a spring support hole is formed in either the rail or the engaging portion, and a spring is accommodated in the spring support hole to provide frictional resistance to movement of the box. In the rail structure of the ashtray, a sliding plate made of resin is interposed between the spring and a member of the rail and the engaging portion on the side where the spring is not accommodated.

[Function] In the rail structure of the vehicle ashtray configured as described above, the spring and the mating member do not come into direct contact;
Since contact is made through the sliding plate, sliding occurs between the resin sliding plate and the engaging portion or rail made of the resin member. In other words, since the resin slides against the resin, the sliding properties are extremely good, and the wear resistance and operation feel are greatly improved, and there is no need to apply grease, and it can be inserted simply by inserting it. It becomes possible to assemble it to the retainer, and the intended purpose is achieved.

[Embodiments] Hereinafter, preferred embodiments of the rail structure of the vehicle ashtray of the present invention will be described with reference to the drawings.

First Embodiment FIGS. 1 to 4 show a first embodiment of the present invention. As shown in FIG.
a, a retainer 1 having side walls 1b, 1b, rails 2, 2 made of resin and having a U-shaped cross section and fixed to the side walls 1b, 1b of the retainer 1; It consists of three boxes. The box 3 can be moved in and out of the retainer 1 by slidably engaging the rails 2 with engaging parts 4, 4 made of resin provided on both sides in the width direction of the ashtray. has been done.

As shown in FIG. 2, a spring support hole 5 is formed in either the rail 2 or the engaging portion 4 (in the illustrated example, on the rail 2 side). A metal spring 6 is housed therein. Spring support hole 5 is connected to rail 2
When provided in the U-shaped cross section, it may be provided in any of the upper piece, the lower piece, and the piece connecting the upper piece and the lower piece. Further, although the illustrated example shows a case where the spring 6 is made of a leaf spring, it may be made of other springs, such as a coil spring.

Between the spring 6 and the member on the side where the spring 6 is not housed, in the illustrated example, the engaging portion 4,
A sliding plate 7 made of resin is interposed. In the first embodiment, one end of the sliding plate 7 is integrated with the rail 2, and extends from the rail 2 in the form of a tongue. FIG. 3 shows the vicinity of the spring storage portion on a larger scale than in FIG. 2.

As shown in FIG. 4, the spring 6 pushes the mating member, in the illustrated example, the engaging portion 4, through the sliding plate 7, and provides frictional resistance to the movement of the box 3 into and out of the retainer 1. No grease is applied to the sliding parts.

To explain the operation of the vehicle ashtray having the above structure, when the box 3 is moved in and out of the retainer 1, the spring 6 pushes the sliding member, in the illustrated example, the engaging part 4, and moves the box 3 appropriately. However, since the spring 6 pushes the mating member via the sliding plate 7, the actual sliding occurs between the sliding plate 7 and the mating member, and the friction between the resin members Since the sliding movement is between the two, the sliding movement is smooth, the operation feeling is smooth, and the abrasion resistance is good, and smooth sliding performance can be obtained even without applying grease. Further, since the spring 6 can be assembled to the retainer 1 simply by fitting the spring 6 into the spring support hole 5, it is easy to assemble.

Second Embodiment FIG. 5 shows only the vicinity of the spring of the second embodiment of the present invention. In the second embodiment, a spring support hole 5 is formed in either one of the rail 2 and the engaging portion 4 (rail 2 in the illustrated example).
A spring 6 is housed in the spring 6, and a sliding plate 8 made of resin is interposed between the spring 6 and a mating member (the engaging portion 4 in the illustrated example). The sliding plate 8 is formed separately from the one member, and is supported by protrusions 9 formed at both ends of the spring support hole 5 of the one member so as not to easily come off. Other configurations are similar to the first embodiment.

Also in this embodiment, the spring 6 is connected to the sliding plate 8.
The mating member is pushed through the box 3 to apply an appropriate frictional resistance to the movement of the box 3 into and out of the retainer 1. However, since the sliding is performed between the resin members, the effect is similar to that of the first embodiment. is obtained.
