Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an improvement in the support structure of an automobile ashtray.

(Prior Art) Conventionally, as shown in FIG. 1, an automobile ashtray has an outer case 1 attached to the vehicle body,
Many cases have a structure in which an inner case 3 is supported so as to be openable and closable by a hinge shaft 2 supported at both ends by both side walls 1a and 1b of the outer case 1.

By the way, as shown in FIG. 2a, the hinge shaft 2 has a coil spring 4 wound around one small diameter portion 2a, the other shaft end 2b is inserted into the hinge hole 1c of the side wall 1a, and then the other shaft end 2b is inserted into the hinge hole 1c of the side wall 1a. Insert the small diameter shaft end 2c into the hinge hole 1d of the side wall 1b, and
A retaining ring 5 is fitted to the retaining ring 5 to prevent it from coming off, or the small diameter shaft end 2c is caulked to prevent it from coming off, as shown in FIG. 2b.

However, since the work of fitting the retaining ring 5 onto the hinge shaft 2 or the work of caulking the hinge shaft 2 is required, there is a problem that the assembly workability is poor.

(Purpose of the invention) The present invention was made to solve the above problem, and rationally utilizes a coil spring that biases the inner case in the opening direction to perform the retaining ring fitting work,
The basic purpose is to reliably prevent the hinge shaft from coming off without the need for caulking work.

(Structure of the invention) Therefore, in the present invention, both ends of the hinge shaft are formed into small diameter parts, a coil spring is wound around one of the small diameter parts of the hinge shaft, and one end of the coil spring is locked to the inner case side. The coil spring is configured to bias the inner case in the opening direction, and to lock the other end of the coil spring to the outer case side to bias the hinge shaft in the axial direction toward the other small diameter portion. .

(Effects of the invention) According to the invention, the other end of the coil spring wound around one small diameter part of the hinge shaft axially biases the hinge shaft toward the other small diameter part. Since the hinge shaft is prevented from moving in the direction of removal by the biasing force of the coil spring, removal can be reliably prevented without fitting a retaining ring or caulking. Further, since only the other end of the coil spring is processed such as being bent, the number of parts does not increase.

(Example) As shown in FIG. 3, an ashtray 11 to be attached to a car body, for example, a dash board, includes an outer case 14 in which the outer circumferential arc surfaces of fan-shaped side walls 12a and 12b are covered with an outer wall 13, Case 1
The inner case (see inner case 3 in FIG. 1) is supported so as to be openable and closable by a hinge shaft 15 supported at both ends by both side walls 12a and 12b of FIG.

A so-called push mechanism 16 is provided on the inner surface of the right side wall 12a of the outer case 14, which locks the inner case in the closed position with the first push operation and releases the lock with the second push operation. On the outer surface of the wall 12b, there is an oil damper mechanism 1 that meshes with a sector gear (not shown) provided in the inner case and applies a braking force to the opening operation of the inner case.
7 etc. are provided.

On the other hand, both ends of the hinge shaft 15 have small diameter portions 15
a, 15b, and the right small diameter portion 15a fits into the hinge hole 18a of the right side wall 12a,
The left small diameter portion 15b is the hinge hole 18b of the left side wall 12b.
A coil spring 19 is wound around the right small diameter portion 15a, and the right small diameter portion 15a is fitted with a coil spring 19.
As shown in Fig. 4a, when the coiled spring 19 is wound and deeply fitted into the hinge hole 18a,
The left small diameter portion 15b is set to a length l that allows the left small diameter portion 15b to fit into the hinge hole 18b from the axial direction.

The coil spring 19 has left and right ends 19a, 19
b is formed in an open inverted V shape in its natural state, and the left end 19a is engaged with the inner case to bias the inner case in the opening direction, and the right end 19b is opened in the direction of the right side wall 12a. It is bent and locked into the locking groove 12c of the right side wall 12a, thereby urging the hinge shaft 15 toward the left small diameter portion 15b, that is, toward the left side wall 12b.

With the above configuration, the coil spring 19 is wound around the right small diameter portion 15a of the hinge shaft 15, and first,
As shown in FIG. 4a, the right small diameter portion 15a is connected to the right side wall 12
a deeply into the hinge hole 18a, and then as shown in FIG. 4b, insert the left small diameter portion 15b into the left side wall 12b
The coil spring 19 is fitted into the hinge hole 18b of the coil spring 19.
When the right end 19b of the hinge shaft 15 is locked in the locking groove 12c of the right side wall 12a, the hinge shaft 15
With both ends supported by a, the distance between the left and right ends 19a and 19b of the coil spring 19 is narrowed, and as a result, a spring force is generated in the coil spring 19 in the axial direction, and the right end 19b causes the coil spring 19 to move toward the left side wall 12b. The shoulder of the left small diameter portion 15b is biased against the left side wall 12b.

Therefore, the hinge shaft 15 is always urged toward the left side wall 12b by the right end 19b of the coil spring 19, so that movement in the direction of withdrawal, that is, toward the right side wall 12a, is prevented, thereby preventing the hinge shaft 15 from coming off.

The above embodiment had a configuration that only considered preventing the hinge shaft 15 from coming off, but as shown in FIG.
In addition to preventing the hinge shaft 15 from coming off, it may also be configured to adjust the speed of the opening operation of the inner case. Note that parts having the same structure and function as those in FIG. 3 are given the same numbers, and explanations thereof will be omitted.

In FIG. 5, the right small diameter portion 15 of the hinge shaft 15
The adjustment lever 22 is loosely fitted in the hole 22a facing the right end 19b of the coil spring 19, and a locking hole 22b is provided in the lower bent portion 22a of the adjustment lever 22, and the coil spring 19 is inserted into the locking hole 22b. The right end 19b is inserted and locked, and the upper end bent portion 22c of the adjustment lever 22 is made to protrude outward from the arc-shaped elongated hole 12d formed in the right side wall 12a.

In the lower part of the elongated hole 12d of the right side wall 12a, pin holes 23 are provided at a predetermined pitch along the elongated hole 12d.
..., 23 are provided, and as shown in FIG. 6a, a pin hole 23,
..., 23 is provided with a detachable pin 24.

The adjustment lever 22 is biased toward the right side wall 12a by the right end 19b of the coil spring 19, and its lower part is connected to a protrusion 12e formed on the right side wall 12a.
When the upper part of the adjustment lever 22 is pushed outward as shown in FIG. It swings so that it comes out of the pin hole 23.

With the above configuration, the hinge shaft 15 is connected to both side walls 12a and 12b in the same manner as the embodiment shown in FIG.
When the right end 19b of the coil spring 19 is inserted into the locking hole 22b of the adjustment lever 22 and locked, the hinge shaft 15 is biased toward the left side wall 12b, and the shoulder of the left small diameter portion 15b is moved to the left side. It is held against the wall 12b and is prevented from moving toward the right side wall 12a, thereby preventing it from coming off.

On the other hand, the adjustment lever 22 has a pin 24 that is connected to the pin hole 2.
3, and the spring force of the coil spring 19 is determined by the relative angle between the left end 19a that is locked to the inner case and the right end 19b that is locked to the locking hole 22b of the adjustment lever 22. will be determined.

Therefore, if the viscosity of the grease in the oil damper mechanism 17 that applies braking force to the opening operation of the inner case changes due to the temperature difference between summer and winter, or decreases due to evaporation, etc., the braking force changes. , push the upper part of the adjustment lever 22 outward to remove the pin 24 from the pin hole 23, rotate the adjustment lever 22, and remove the coil spring 1.
After changing the angle of the right end 9b of 9, adjust the adjustment lever 22.
By engaging the pin 24 in the nearest pin hole 23, the braking force of the oil damper mechanism 17 can be adjusted to a constant level by changing the spring force of the coil spring 19.
