Description

[Detailed description of the invention] (Field of industrial application) This invention relates to ashtrays used in vehicles such as buses, trains, ships, etc. Regarding the shaft mounting structure.

(Prior Art and Problems to be Solved by the Invention) Ashtrays for vehicles, especially ashtrays whose lids and case bodies are opened and closed by rotation, are already known and are installed on the walls of trains such as railcars. It is becoming. However, this conventional ashtray had the following defects. That is, first of all, regarding the lid,
As the lid is only supported rotatably and is not held in a fixed position, vibrations from the vehicle can cause the lid to pop up, creating noise, or cause the lid to topple over and close. There was this inconvenience. In addition, when cleaning the case body, the opening is directed downward and the cigarette butts inside are taken out, but during this operation, the center of gravity of the case body shifts and the cigarette butts are taken out. There was an inconvenience that it rotated and failed to catch the cigarette butt.

This invention was devised to eliminate these defects, and its objectives are: (a) The lid can be opened or closed without being affected by the vibrations of vehicles such as railcars. (b) Also, to provide a mounting structure for a rotation shaft of a vehicle ashtray, which can be held securely and (b) also prevent the case body from suddenly rotating downward due to a shift in the center of gravity even when the opening is directed downward. be.

(Means for Solving the Problems) In order to achieve the above object, a mounting structure for a rotating shaft of a vehicle ashtray according to this invention has the following structure. That is, support holes are provided on the outer surfaces of the left and right side walls of the lid or the case body, into which the rotation shafts protruding from the inner surfaces of the left and right side plates are inserted. Further, on the outer surface of at least one side wall, an elastic member mounting recess is provided in communication with the support hole. A resilient member is disposed in the resilient member mounting recess for elastically holding the base end flat portion of the rotating shaft to be inserted into the support hole.

(Function) The lid or the case body is elastically held by a resilient member that clamps the base end of the pivot shaft. By applying a force that resists the elasticity of the resilient member, the lid or the case body can be rotated.

Because the case rotates with elasticity, the center of gravity does not shift all at once, allowing the case body to gradually rotate downward.

(Embodiment) Hereinafter, as an embodiment of this invention, an ashtray installed in a vehicle will be described based on the drawings. In the figure, 1 indicates the entire ashtray that can be attached to the seat or inner wall of a vehicle. This ashtray 1 has a disassembly assembly structure, and includes left and right side plates 2, 3, a lid 4 rotatably held between the side plates 2, 3, a case body 5, and a case body 5. It consists of a rubbing eraser fitting 6 to be attached, and an attachment back plate 7.

First, let me explain about the left and right side plates 2 and 3.
Rotation shafts 8, 9 and 10, 11 located above and below are respectively protruded from the inner surface thereof. However, the base ends of the rotation shafts 9 and 11 of the side plates 3 are both thicker than the distal ends, and a plurality of flat parts 12 and 13 are formed on the outer periphery of the base ends. (See Figure 7). That is, the base end of the rotation shaft 9 is
It has a rectangular cross section with four flat parts 12, and each corner is chamfered or rounded. Further, the base end of the rotating shaft 11 is provided with two flat parts 13 facing each other, and the outer periphery connecting these two flat parts 13 is a smooth circular arc surface 14.

Reference numerals 15 and 16 are mounting pieces with screw holes H provided on the upper inner surfaces of the side plates 2 and 3, so that the above-mentioned rubbing eraser 6 can be fixed between the side plates 2 and 3 with screws. . A recess 17 is formed in the center of the front of the rubbing eraser 16, into which a finger can be inserted to open and close the lid 4 or the case body 5.

Next, the lid 4 is made of a substantially rectangular thin plate,
A soundproof cushioning member 18 such as a packing made of rubber or the like is attached to the inside of the tip in order to soften the impact on the rubbing eraser 6. Further, bosses 2 are provided at the base ends of the left and right side walls 19, 20 of the lid 4.
1 and 22 are formed, and support holes 23 and 24 into which the rotation shafts 8 and 9 are inserted are formed on the outer surface thereof.

A boss 22 of at least one side wall 20
In addition to the support hole 24, there is a resilient member mounting recess 25.
are provided in a continuous manner. This mounting recess 25 is located concentrically with the support hole 24 and is opened larger than the support hole 25 . Moreover, as clearly shown in FIG. 6, upper and lower notches 27 extending left and right are formed, so that leaf spring-like resilient members S can be arranged in parallel at predetermined intervals. Therefore, these elastic members S elastically sandwich the rotation shaft 9 inserted into the support hole 24, specifically, the plane portion 12 provided at the base end thereof from two directions, and the lid 4 can be freely moved. Prevents rotation. Reference numeral 28 indicates a relief for each of the resilient members S.

Next, the case body 5 is an upright container with a substantially rectangular opening at the top, and bosses 31, 32 are provided at the bottom of the left and right side walls 29, 30.
is formed. And these bosses 31,3
Support holes 33 and 34 into which the rotation shafts 10 and 11 are inserted are formed on the outer surface of the support holes 2 . However, the boss 32 of at least one side wall 30 is provided with a support hole 34 and an elastic member mounting recess 35 in communication with each other. The mounting recess 35 has the same structure as the mounting recess 25 described above, and includes a resilient member S that elastically holds the flat portion 13 provided at the base end of the rotating shaft 11. 36 is a notch for arranging the resilient members S in parallel, and 37 is a relief.

The side plates 2 and 3, which rotatably hold the lid 4 and the case body 5, are fixed to the mounting back plate 7 by suitable means such as screws. This mounting back plate 7 is provided with screw holes 38,
The ashtray 1 can be fixed to the seat or inner wall of a vehicle with screws.

In this embodiment, an example has been described in which the resilient members S disposed in the mounting recesses 25 and 35 are divided into upper and lower parts and arranged in parallel facing each other. However, by simply arranging one flat plate-shaped elastic member S, it is not possible to exert an elastic effect sufficient to withstand the weight of the lid 4 and the case body 5.
Permanent deformation may occur if stress limits are exceeded.
For this reason, it is preferable to arrange multiple pieces of the same elastic member S on the upper and lower sides, but when assembling the ashtray, there may be malfunctions due to incorrect insertion of the elastic member S, or because they are separate pieces. The problem is that it is difficult to assemble. Therefore, instead of using the split elastic member S with a simple shape, for example, the eighth
It is preferable to use an integrally formed resilient member S having various shapes including an elliptical shape or tightly bent resilient pieces as shown in FIGS. a to d. what if,
Even if split elastic members S are used, for example, as shown in FIG. 8e, if the split pin-shaped elastic members S are arranged above and below, the occurrence of permanent distortion can be reliably prevented. be able to.

Further, the mounting recesses 25 and 35 may be provided not only on one side wall of the lid 4 and the case body 5, but also on both side walls.

Now, as described above, the ashtray having the above structure is elastically held by the elastic member S that holds the base ends of the pivot shafts 9 and 11 of the lid 4 and the case body 5. . By inserting a finger into the recess 17 and applying a force that resists the elasticity of the elastic member S, the lid 4 or the case body 5 can be rotated. The lid 4 rotates approximately 90 degrees and stops when it stands upright. In addition, the case body 5 is
It stops after rotating approximately 180 degrees (see Figure 5). As mentioned above, at the base end of the rotation shaft 11,
An arcuate surface 14 connecting the two flat parts 13 is formed. Therefore, the case body 15 rotates smoothly along the arcuate surface 14, and since the elasticity of the resilient member S is effective, the center of gravity does not shift all at once, but gradually rotates downward.

(Effects of the invention) As is clear from the detailed description above, according to the mounting configuration of the rotating shaft of the vehicle ashtray according to this invention, the base end of the rotating shaft is held between the elastic members. , the lid or case body can be held elastically. Therefore, even if there is vibration from the vehicle, it will not be affected by it, and the lid will not jump or fall. Further, since the case body also rotates while the elasticity of the elastic member is acting, the center of gravity does not shift all at once, and it can be rotated slowly downward. Therefore, when cleaning the ashtray, there is no chance of missing butts.
