Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an inside handle device for an automobile door, and particularly to a mechanism for preventing the pivot from coming off.

In conventional inside handle devices for automobile doors, an enlarged diameter head is formed at one end of a shaft that pivotally connects the inside handle to a base plate fixed to the door panel, and after this shaft is inserted through the base plate and the inside handle. The shaft was prevented from slipping out from the inside handle, etc. by attaching a snap spring to the other end of the shaft, or by caulking and expanding the other end of the shaft.

However, the conventional configuration as described above requires a snap spring, etc., and has the disadvantage that the structure is complicated.

Further, after assembling the shaft ends, operations such as caulking are time-consuming and repair is difficult.

In view of the above-mentioned drawbacks, the present invention is an attempt to eliminate this problem, and provides an inside handle for an automobile door in which a shaft cylinder portion of the inside handle is pivotally connected to a base plate fixed to the door. In the device, an elastic tongue piece is provided on at least one side of the shaft cylindrical portion of the inside handle, and the elastic tongue piece is provided with an inwardly inclined shape before assembly, and the elastic tongue piece is arranged in an inwardly inclined state. In some cases, a shaft hole is bored that is aligned with the shaft hole of the shaft tube portion and is offset from the shaft hole of the shaft tube portion by raising the elastic tongue piece, and the shaft hole is inserted into both shaft holes. After the elastic tongue is inserted, the elastic tongue is raised and the shaft hole edge of the elastic tongue is brought into contact with the end surface of the shaft, thereby preventing the shaft from coming off from the inside handle. It is what it is.

The present invention will be described in detail below based on an illustrated embodiment.

Reference numeral 1 denotes an automobile, and a front door 3 is attached to both sides of the front part of a body 1a of the automobile 1 with a pair of hinges 2 so as to be openable and closable. A door lock device 4 is installed.

Reference numeral 5 denotes an inside handle device, which is provided on the inside of the front door 3 and linked to the door lock device 4 via a connecting rod 6.

The schematic structure of the inside handle device 5 is as follows.
As clearly shown in FIGS. 4 to 4, there is a U-shaped base plate 7 attached to the inner panel 3a of the front door 3, and upper and lower parts provided so as to pass through both the upper piece 7a and the lower piece 7b of this base plate 7. It consists of a shaft 8 that defines a direction, and an inside handle 9 in the shape of a rectangular frame that is pivotally connected to this shaft.

The inside handle 9 is made of a hard synthetic resin material having appropriate elasticity, and includes a handle portion 10 having a rectangular frame shape when viewed from inside the vehicle.

Horizontal bearing pieces 11, 12, and 13 facing toward the inner panel 3a are provided at the center portion of the back surface of the base end side (the right end portion in FIGS. 2 and 3) of the handle portion 10, and at the upper and lower portions thereof, respectively. Each of the shaft bearing pieces 11, 12, 13 is provided with a vertical shaft hole 14 that is aligned with each other. Thus, these shaft bearing pieces 11, 12, and 13 form a shaft cylinder portion of the inside handle 9.

A protruding piece 11 is further provided at the free end of the central shaft bearing piece 11.
a is extended, and this protruding piece 11a is provided with an engagement hole 15 in the vertical direction, and a bent end portion bent at right angles to one end of the connecting rod 6 is formed in this engagement hole 15. 6a can be fitted and locked via a suitable holder 16.

As shown in FIG.
In the state before assembly, a pair of elastic tongues 17 are provided so as to protrude inwardly from each other by an angle θ with respect to a perpendicular 1 extending vertically from the back surface of the handle portion 10 .

A reinforcing rib 17a is provided inside the base of the elastic tongue 17 to increase the strength of the base.

Each elastic tongue piece 17 has a sixth elastic tongue piece 17.
When in the inwardly inclined state as shown in the figure, by aligning with the shaft holes 14 of the shaft bearing pieces 11, 12, and 13 and standing up the elastic tongue pieces 17 as shown by imaginary lines in FIG. The center axis C ₁ is the bearing piece 11,
The shaft hole 18 is bored so as to be offset by a distance D from the center line _C2 of the shaft holes 12 and 13.

Therefore, in order to attach this inside handle 9 to the base plate 7, it is necessary to attach the inside handle 9 to the base plate 7.
Shaft hole 19 bored in upper piece 7a and lower piece 7b
Then, the shaft bearing pieces 11, 12, 13 are fitted between the upper piece 7a and the lower piece 7b of the base plate 7 so that the shaft holes 14 of the bearing pieces 11, 12, 13 are aligned, and these shaft holes 14, 19 are fitted. The shaft 8 is inserted from one side into the shaft hole 18 of the elastic tongue piece 17 which is in an inwardly inclined state.

Thereafter, as shown in FIG. 5, by raising the upper and lower elastic tongues 17 in the direction of arrow a,
The end of the shaft 8 is removed from the shaft hole 18, and the edge of the shaft hole 18 is brought into contact with the end surface of the shaft 8. At this time, the central axis C ₁ of the shaft hole 18 of the elastic tongue piece 17 is
As mentioned above, the shaft holes 1 of the shaft bearing pieces 11, 12, 13
₄ , this misalignment allows the elastic tongue 17 to abut against the end of the shaft 8.

By erecting the upper and lower elastic tongues 17 in this manner, the shaft 8 is held between the two elastic tongues 17 and is completely prevented from coming off from the inside handle 9.

20 is a central shaft bearing piece 11 and a lower shaft bearing piece 13
One leg piece 20a is wound around the shaft 8 between the inside handle 9 and the other leg piece 20
b are respectively locked to the vertical surfaces of the base plate 7, and the inside handle 9 is always biased clockwise in FIG. 3 by the coiled springs 20.

21 is a stopper cut and raised from the base plate 7, and when the inside handle 9 is in the closed state, a protruding piece 12a extending from the upper shaft bearing piece 12
However, it comes into contact with the front end of this stopper 21 and stops.

Reference numeral 22 shown in imaginary lines in FIGS. 2 and 3 is a decorative frame that covers the inside handle device 5.
It is fitted into an opening 24 for mounting the inside handle 9 formed in the trim 23 of the front door 3.

In this embodiment configured as described above, by pulling the handle portion 10 of the inside handle 9 counterclockwise as shown by the arrow b in FIG. 3 against the biasing force of the coiled spring 20, By pulling the connecting rod 6, the engagement of the door lock device 4 can be released, and by releasing the hand from the handle 10, the inside handle 9 is moved to the first position in contact with the stopper 21 by the biasing force of the coiled spring 20. It is rotated back to the closed state shown in Figure 3.

As explained in detail above, according to the present invention,
By forming an enlarged diameter head on one end of the shaft, using a snap spring, etc., or by raising the elastic tongue piece provided on the inside handle and deflecting the shaft hole without performing caulking work. , it is possible to prevent the shaft from coming off.

Therefore, the structure of the inside handle device is simple, the assembly work is easy, and there are advantages that it can be manufactured at low cost.

In addition, by forcibly tilting the elastic tongue piece inward, the shaft hole of the elastic tongue piece is aligned with the shaft, and the shaft can be pulled out and the inside handle device can be easily removed, making repairs easy. There are also advantages to doing so.

In the above-mentioned embodiment, shaft holes were formed in both of the pair of elastic tongues of the inside handle, but even if one of the elastic tongues was not provided with a shaft hole and was used simply as a stopper, A similar effect can be obtained.
