Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an inner handle device for an automobile door, and particularly to an improvement in an assembly structure for assembling an inner handle to a handle case.

2. Description of the Related Art Inner handle devices provided on the inside of an automobile door are well known, and the automobile door can be locked or unlocked from the inside by operating the inner handle.

By the way, as shown in FIG. 1, the inner handle 1 is housed in the handle case 2, and the shaft 3 inserted laterally through the handle case 2 allows
In an inner handle device that supports the inner handle 1 in a swingable manner, it is necessary to support the shaft 3 so that it does not come off.For this reason, in the past, a groove was cut in the shaft and a retaining ring was fitted to prevent the shaft from being removed. The shaft was made non-removable, or the end of the shaft was crushed, or the handle case was heat-sealed to prevent the shaft from coming off. However, all of them have the problem of very poor assembly performance, and recently, as shown in Fig. 1, a spring pin is used as the shaft, and this spring pin is inserted into the insertion hole 4 made in the handle case 2 using a press-fitting jig. , 4 is forcibly press-fitted.

When using such a spring pin,
Although it has the advantage of improving ease of assembly to some extent,
A press-fitting jig is required, and in order to reliably support the press-fitted spring pin on the inner periphery of the insertion holes 4, 4, it is necessary to The disadvantage was that the wall thickness had to be increased, making it uneconomical in terms of materials and heavy.

The present invention has been developed in view of these problems, and allows the shaft that swingably supports the inner handle to be inserted extremely easily without using a press-fitting jig. An object of the present invention is to provide an inner handle device for an automobile door whose shaft can be made non-removable and which eliminates the need to increase the thickness of the side wall of the handle as in the past.

Therefore, in the present invention, the inner handle is surrounded by a handle case, and a shaft for swingably supporting the lower part of the inner handle is supported between a pair of left and right side walls provided in the handle case. In the inner handle device for an automobile door, a door lock device connected to the inner handle via a connecting member can be actuated by swinging the inner handle. A bearing that is formed at different levels by a wall provided on the upper side and a wall provided on the lower side, and the end of the shaft is supported by the upper wall and the lower wall. The outer end of one bearing hole is closed off from the outside by a stopper wall formed integrally with the wall, while the other bearing hole has elastic deformation that extends from the outside along the extension line of this bearing hole. An elastic locking piece is formed integrally with the wall, and elastic deformation of this elastic locking piece allows insertion of the shaft, and when the shaft is completely inserted, it returns to its original state and the end of the shaft cannot be removed. The basic configuration is such that it can be locked.

Hereinafter, the present invention will be described in more detail based on illustrated embodiments.

In FIG. 2, 10 is an inner handle made of a synthetic resin molded product, 11 is a handle case also made of a synthetic resin molded product, and 12 is a metal shaft that supports the inner handle 10 in a swingable manner.

As shown in FIGS. 4 and 5, the bearing portion is formed of wall portions 13b and 14b provided on the upper side of each, and wall portions 13a and 14a provided on the lower side of each, It is adapted to receive the shaft 12.

The shaft 12 is formed by the upper wall 13b and the lower wall 13a of the right (one) side wall 13 in FIG.
The end portion thereof is a bearing hole 15 for receiving a bearing. The bearing hole 15 is formed to have approximately the same diameter as the shaft 12. Note that the upper wall portion 13b and the lower wall portion 13a are formed at different levels in the axial direction so that they can be molded using a pair of molds in the vertical direction. The outer end of the bearing hole 15 is closed by a stopper wall 16 formed as an outer wall of the handle case, and one end of the shaft 12 is inserted into the bearing hole 15 with the shaft 12 prevented from being pulled out. bearing part. On the other hand, the upper wall 14b and the lower wall 14a of the left (other) side wall 1 in FIG. 2 form a bearing hole 17 for bearing the other end of the shaft 12. This bearing hole 17 is also formed to have a diameter substantially equal to the diameter of the shaft 12. An elastic locking piece 18 extending from the outer wall side of the handle case 11 toward the end of the shaft 12 inserted into the bearing hole 17 is integrally formed when the handle case 11 is molded. This elastic locking piece 1
8 is elastically deformed upward into the bearing hole 17 when the shaft 12 is inserted, allowing the shaft 12 to be inserted, and when the shaft 12 is inserted until it is stopped against the right stopper wall 16 side, the opposite side of the shaft 12 The shaft 12 is restored by its own elasticity to the position where it contacts the end face of the shaft 12, and thereafter the shaft 12 can be prevented from coming off in the axial direction between the shaft 12 and the stopper wall 16.

The inner handle 10 is swingably supported by a shaft 12 inserted through a shaft insertion hole provided in each of the pair of legs and a connecting portion 10d to the locking device side extending largely downward from the center. Ru. This connecting portion 10d protrudes downward from an opening hole 19 provided at the center of the bottom of the handle case 11, and as shown in FIG. 3, its lower end is an end of a link rod 21 that is connected to a lock mechanism (not shown) are connected to each other via a joint 20.

Further, as shown in FIG. 3, the inner handle 10 has one end fixed to the bottom surface of the handle case 11 and the other end attached to a helical spring 22 that is engaged with the middle part of the connection part of the inner handle 10. Therefore, as shown in FIG. 3, it is normally supported in a state where it rests against one side edge of the bottom opening 19 of the handle case 11.

From this state, when the inner handle 10 is rotated around the shaft 12 as shown by arrow B in FIG.
The link rod 21 connected to d is pulled, thereby unlocking a locking device (not shown).

As is clear from the above description, in the present invention, the inner handle 10 is surrounded by the handle case 11, and the shaft 12, which is the pivot axis of the inner handle 10, is provided on the handle case 11 with a pair of left and right side walls 13. . The shaft bearing portions of the side walls 13 and 14 are connected to the wall portion 1 provided on the upper side of each side wall 13, 14.
3b, 14b and the wall portions 13a, 14a provided on the lower side thereof are formed in different steps, and the wall portions 13b, 14b on the upper side and the wall portion 13 on the lower side are formed in different levels.
a and 14a form bearing holes 15 and 17 that bear the end of the shaft 12, and each of the bearing holes 15 and 17 is formed approximately equal to the diameter of the shaft 12, and the outer end of one of the bearing holes 15 is formed in a wall portion. 13a, 13
b is closed off from the outside by a stopper wall 16 formed integrally with b, while the other bearing hole 17 has a stopper wall 16 extending from the outside along the extension line of this bearing hole 17;
An elastic locking piece 18 that allows insertion of the shaft 12 through elastic deformation, and that restores its original shape and locks the end of the shaft 12 irremovably when the shaft 12 is completely inserted into the bearing hole 17, is attached to the wall portion 14a. , 14b.

According to the present invention, firstly, the shaft can be easily inserted by hand, and the inserted shaft can be held between the elastic locking piece and the stopper wall so that it cannot be removed. According to the present invention, secondly, the wall portion is stepped in the axial direction of the shaft.
The inner handle case, including the wall portion, stopper wall, and elastic locking piece, can be easily molded using a pair of upper and lower molds, making it extremely easy to mold the inner handle case. The wall thickness of the side wall of the shaft can be made sufficiently thin because it is sufficient to simply bear the shaft and there is no need to prevent the shaft from coming off by press-fitting the shaft as in the conventional case. Therefore, it is extremely advantageous in terms of the weight and material of the inner handle case, and overall ease of assembly is significantly improved, making it possible to make a product at low cost. Furthermore, the bearing part is formed at different levels between the upper wall part and the lower wall part, and the bearing hole is made approximately equal to the diameter of the shaft, so there is no play between the shaft and the handle case. This provides advantages such as the ability to reduce backlash between the inner handle and the handle case.
