Description

[Detailed Description of the Invention] This invention relates to the structure of assembling a protector in an automobile ashtray.

Conventionally, in an automobile ashtray, a protector is assembled as shown in FIG.

In the illustrated protector 5, the spring pieces 6.6 attached to both sides of the protector 5 are screwed into the boss portions B, B, which are protruded from the inside of the ashtray body 1, using a self-tapping screw. installed by.

Therefore, in this type, since the screwing operation is troublesome, assembling the protector 5 itself becomes troublesome.

In addition, the ashtray main body 1 is usually molded from a synthetic resin material such as phenol resin, and when the tapping screw TS is screwed in, the boss portion B may crack.

The present invention has been devised in view of the above.

The purpose is to provide a structure for assembling a protector in an automobile ashtray in which the protector can be easily and reliably assembled.

An embodiment of the present invention will be described below with reference to the drawings.

The ashtray according to this example is attached to a dash board of an automobile so that it can be taken in and out, and is composed of an ashtray main body 1 and a protector 5.

The ashtray main body 1 is made of a synthetic resin material, and has an ash receiving part IA formed therein.

Moreover, a pair of blocks 2, 2 for attaching the protector 5 are each integrally provided upright on both sides of the back side of the ash receiving part IA.

The upper surface of each pair of blocks 2.2 is recessed with a fitting groove 3 that can fit with both spring pieces 6, 6 of the protector 5, and an insertion shaft 4 is integrally protruded from the center thereof. ing.

The protector 5 is made of a thin metal plate and is designed to cover most of the ash receiving portion 1A.

Further, the protector 5 has rectangular notches on both sides of the rear side, and spring pieces 6.6 made of spring steel are disposed in each of the rectangular notches.

The spring piece 6 is used to flip up the protector 5, which is normally covered over the ash receiving part IA, when the ashtray main body 1 is pulled out, thereby opening the ash receiving part IA.

Although not shown in detail, each of the spring pieces 6, 6 is attached by inserting one end thereof into the protector 5 side and then caulking the spring pieces 6, 6.

On the other hand, a support i6A that can be fitted into the fitting groove 3 is formed on the other end side of both spring pieces 6, 6, and furthermore, a support i6A that can be fitted into the fitting groove 3 is formed at the center of the upper surface of the support 6A. An annular fitting portion 7 is formed.

The fitting portion 7 has an insertion hole 8 formed in its center with a diameter slightly smaller than that of the insertion shaft 4, and the insertion hole 8 has a plurality of biting pieces 9 to 9 that can be deformed in the direction of expanding the insertion hole 8. is surrounded by.

Each biting piece 9 to 9 is formed by making notches of a certain length at equal intervals in the radial direction from the periphery of the insertion hole 8 and standing up slightly upward, thereby allowing the insertion shaft 4 to While the insertion is allowed, after insertion, it bites into the insertion shaft 4 and is prevented from being removed.

As described above, according to this example, the protector 5 is assembled by simply press-fitting the fitting portions 7 of the spring pieces 6 into the insertion shafts 4 of the corresponding blocks 2.

That is, when the spring piece 6 is strongly pushed into the insertion shaft 4 while the insertion hole 8 of the fitting part 7 is fitted, the spring piece 6 is inserted while pushing and expanding the biting pieces 9 to 9.

When the support portion 6A of the spring piece 6 is fitted into the fitting groove portion 3 of the block 2, the protector 5 itself is prevented from rotating.

Further, when the protector 5 is opened and closed with respect to the ash receiving portion IA and an external force is applied to the spring piece 6 in the direction of its removal, each of the biting pieces 9 to 9 bites into the insertion shaft 4 and is removed. can be strongly resisted.

In this example, the case where the insertion shaft 4 for attaching the protector 5 is formed on the upper surface of the block 2 protruding from the bottom surface of the ash receiving part 1A is illustrated, but instead of this, it is formed on the back side of the ashtray body 1. It may be of a type in which only the insertion shaft 4 is provided protruding from the inner wall surface.

By doing so, the effective capacity of the ashtray main body 1 can be increased.

As described in detail above, according to the present invention, the protector can be firmly assembled by simply aligning the insertion hole of the spring piece with the insertion shaft formed on the ashtray body side and pushing it in.

Therefore, unlike in the past, the protector does not require any screws to be assembled, making it extremely simple and inexpensive.

In addition, unlike the conventional method, cracks caused by screwing can be avoided.

Claims (1)

[Scope of utility model registration request] In an ashtray that is removably attached to a car dash board, etc., the protector that covers the ash receptacle of the ashtray body in an openable and closable manner is attached to the back side of the protector, which protects the ashtray body from its elastic force when the ashtray body is pulled out. The operating end side of the spring piece that opens the ash tray is attached to the spring piece, while the supporting end side of the spring piece is fitted with an insertion hole that can be inserted into the insertion shaft provided opposite to the ashtray body side. The assembly structure of the protector in an automobile ashtray is characterized by a suitable number of bite pieces arranged around the insertion hole to prevent the insertion shaft from being removed.
