Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a mounting structure for a fire cut plate of an automobile ashtray.

[Prior Art] Conventionally, as shown in FIG. 3, in an automobile ashtray, an inner case 2 is supported by flanges 1 and 1 on both sides so as to be pushed into and pulled out of an outer case (not shown) provided on the body side. A fire cut plate 4 is pivotably supported by a hinge pin 3, and when the inner case 2 is pulled out, the fire cut plate 4 is pivoted by the biasing force of a coil spring 5.
It has been proposed that the oscilloscope is made to swing upward.

[Problems to be solved by the invention] By the way, in the above ashtray, horizontal through holes 7, 7 are provided in both side walls 6, 6 of the inner case 2, so that the hinge pin 3 can be inserted from the outside of the inner case 2. It is inserted into one of the through holes 7, then into the holes of the curled parts 8, 8, which have an arcuate cross section provided in the coil spring 5 and the fire cut plate 4, and then into the other through hole 7 of the inner case 2. However, according to this mounting method, after aligning the holes of the through holes 7, 7, coil spring 5, and curling parts 8, 8, the hinge pin 3 is attached. Since they must be inserted into each one in turn, there is a problem in that the installation work becomes extremely complicated.

Further, after the fire cut plate 4 is assembled, the through holes 7, 7 are filled with adhesives 9, 9 to prevent the hinge pin 3 from coming off. Not only was the cost high, but the reliability of the retainer was also poor.

[Means for Solving the Problems] The present invention aims to solve the above-mentioned problems. Specifically, the present invention includes an outer case provided on the body side, and a device supported by the outer case so as to be inserted into and pulled out from the outer case. The inner case is slidably supported at one end by a hinge pin whose both ends are fixed to fixing parts provided at the upper ends of both side walls in the insertion and withdrawal directions of the inner case, and the hinge pin is slidably supported at one end side. In an automobile ashtray comprising a fire cut plate whose other end is biased upward by a spring member attached to the ashtray, the portion where the hinge pin is fixed on each side wall of the inner case has a width approximately equal to the diameter of the hinge pin. and a groove portion extending closer to the outer surface than the inner surface in each of the side walls in a direction substantially perpendicular to the direction of insertion and withdrawal of the inner case, and at least one of the grooves in the side wall has a bottom surface curved upward. The side wall has a curved surface and a vertical hole at the outer end of the side wall, and when the hinge pin is fitted into the groove part of the side wall of the inner case and fixed, the hole with the hole is formed. It is characterized by having an elastically deformable part that fits into the groove and curves along the curved surface in an elastically deformed state, and then fits into the hole and prevents it from coming off.

[Operations and effects of the invention] According to the mounting structure of the invention as described above, the hinge pin is inserted into the fire cut plate in advance, and both ends of the hinge pin are inserted into the grooves provided on both sides of the inner case. Since the fire cut plate can be attached to the inner case by fitting it into the inner case from above, the fire cut plate can be attached extremely easily. At this time, since the outer end of the groove is closed, the hinge pin will not come out outward.

Further, according to the present invention, the bottom surface of the groove for fixing the hinge pin to the side wall of the inner case is curved upward and has a hole, and the elastically deformable portion of the hinge pin that fits into the groove with the hole is in an elastically deformed state. The hinge pin curves along the curved surface and is then inserted into the hole, so as the hinge pin curves along the curved surface of the bottom of the groove, a large elastic force causes the end of the hinge pin to come into pressure contact with the inner surface of the hole. , the hinge pin can be securely fixed to the inner case, and a good retaining effect can be obtained. Moreover, since the above-described slip-out prevention method does not require adhesive, costs can also be reduced.

Furthermore, since there is no need to provide a through hole for inserting the hinge pin in the inner case, the number of man-hours required for machining the inner case is reduced.

[Example] Examples of the present invention will be described below.

As shown in FIGS. 1 and 2, the upper portions of the inner case 20 of the automobile ashtray according to the present embodiment are open at the corresponding positions of the flanges 21, 21,
Grooves 22 and 23 are formed that are closed on the outside,
A vertical hole 24 is bored at the outer end of the inner case 20 in one of the grooves 22 . The bottom of one of the grooves 22 and the top of the hole 24 are
It is continued by a curved surface 25.

The fire cut plate 4 is bent downward by approximately 90 degrees with one end 27 of the hinge pin 26 passing through the holes of the curling portions 8, 8 and the coil spring 5. The hinge pin 26 is fitted into the groove 22 and the hole 24 from above along the surface 25, and the other end 28 of the hinge pin 26 is fitted into the other groove 23 from above.
It is attached to the inner case 20.

In this attached state, one end 27 of the hinge pin 26 that fits into the groove 22 having the hole 24 curves along the curved surface 25 in an elastically deformed state, and then fits into the hole 24 and the hinge pin 26 . It is an elastically deformable part that prevents it from coming off. Due to this elastic deformation portion, a biasing force F toward the outside of the inner case 20 acts on the bent end 27a of the hinge pin 26, so that the curved end 27a is elastically pressed against the inner surface of the hole 24, and the upper part of the hinge pin 26 is prevented from escaping. Moreover, fire cut plate 4
Since an outer case (not shown) is located above the hinge pin 26, it is more difficult for the hinge pin 26 to come off. 29 is a handle; 30, 30, ... are projections for extinguishing a cigarette; 31 is a stopper portion that defines the maximum upward swing angle of the fire cut plate 4; 32 is a stopper portion of the coil spring 5; One end is a latching part. Other parts having the same configuration as those of the conventional example are given the same reference numerals, and explanations thereof will be omitted.

In the above embodiment, the vertical hole 24 was provided only in one groove 22, and the bent end 27a of the hinge pin 26 was fitted therein, but the grooves 22, 2 on both sides
3 is provided with holes in the vertical direction, and both ends of the hinge pin 26 are bent so that they fit into these holes, an even better retaining effect can be obtained.
