Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an inside handle device for an automobile door, and more particularly to a fixing structure for a door inner panel.

As is well known, an automobile door 1 as shown in FIG. 1 is provided with an inside handle 2 linked to a door lock (not shown) in order to enable the door to be unlocked from inside the vehicle. A recent inside handle device has a structure in which the inside handle 2 is pivotally supported inside a resin escutcheon 3 that also serves as a mounting base.
It is proposed by the publication no. That is, FIG. 2 shows the inside handle device disclosed in the same publication.
The rear part of the rod 5 is pivotally supported by a support shaft 4 to an escutcheon 3 which also serves as a mounting base.
It is connected to the inside handle lever of the door lock (not shown) through the handle. For attachment to the door inner panel 6, a protrusion 8 that can be inserted into the locking hole 7 of the door inner panel 6 is formed to protrude from the back surface 9 of the escutcheon 3.
is fixed to the door inner panel 6 with screws 12 using a mounting hole 11 penetrated from the fingertip insertion space A while being located in the opening 10a of the door trim 10. However, according to such a mounting structure of the escutcheon 3, the head 12 of the screw 12 is not attached to the outside.
A is exposed, which not only does not look good, but also prevents the screw head 12a from hitting the fingertip inserted into the fingertip insertion space A and damaging the nail, etc. Therefore, if the inside handle 2 is strongly pulled downward in FIG. 2, the protrusion 8 may come off the locking hole 7 and the escutcheon may tilt.

The present invention has been made in view of the above-mentioned problems in mounting an escutcheon that also serves as a mounting base, and aims to provide a mounting structure in which mounting screws are not exposed to the outside and the mounting state is stable. , in a mounting structure in which a resin escutcheon, which also serves as a mounting base and which pivots an inside handle with an operating part on the front side of the door and a pivot shaft on the rear side of the door from the operating part, is fixed to the door inner panel. , an extension wall parallel to the door inner panel and extending toward the rear of the door on the back surface of the escutcheon; and a locking pawl located forward of the extension wall on the back surface of the recess in which the operating section of the inside handle is accommodated. and a large opening large enough to allow the locking pawl to move in and out at the front side of the door at a fixed position of the escutcheon of the door inner panel, and a width smaller than the large opening at the rear side of the door. Approximately L with a continuous small opening that allows the claw to slide forward and backward.
a letter-shaped mounting hole and a screw hole at a position opposite to the extension wall on the rear side of the mounting hole, and a screw hole is formed in the extension wall on the rear side of the pivot shaft of the inside handle; The present invention proposes a mounting structure for an inside handle device in which the locking pawl is slid against the door inner panel and locked in the mounting hole toward the rear of the door.

Hereinafter, details of one embodiment of the present invention shown in FIGS. 3 to 5 will be described.

FIG. 3 is a sectional view corresponding to FIG. 2 showing the inside handle device according to the present invention, and parts corresponding to FIG. 2 are designated by the same reference numerals. In the illustrated example, the back surface 9 of the escutcheon 3 has a tip 13a.
A pair of L-shaped locking claws 13A, 1 which are bent vertically.
3B are integrally molded, and these locking claws 13
A, 13B are inserted and fixed into a pair of mounting holes 14A, 14B punched into the recess 6a of the door inner panel 6. That is, the mounting hole 1 of the door inner panel 6
4A, 14B are large openings 14a that receive the tips 13a of each of the locking claws 13A, 13B, and large openings 14a that communicate with the rear side of the door of these large openings 14a and that are connected to only the sides 13b of each of the locking claws 13A, 13B. It is composed of a small opening 14b that allows penetration. Therefore, in order to fix the escutcheon 3 to the door inner panel 6, the tips 13a of the locking claws 13A, 13B are
After inserting the escutcheons 3 into the large openings 14a of the mounting holes 14A and 14B, if the escutcheon 3 is slid horizontally toward the rear of the door, the locking claws 13A and 13B will be locked to the door inner panel 6. . In this case, as shown in an enlarged and cutaway view in FIG. 5, at least one of the upper and lower surfaces of the side edges 13b of the locking claws 13A and 13B is scraped by sliding contact with the corresponding surface of the small opening 14b. If the small protrusion 15 is molded in advance, the locking claws 13A, 13B can be fixed without any play in the vertical direction.
can be held in the mounting holes 14A, 14B.

Further, on the rear back surface of the escutcheon 3, an extension wall 17 forming a pair of screw holes 16A, 16B.
is integrally molded. Therefore, the mounting hole 14
After sliding and fixing the locking claws 13A and 13B to A and 14B, screw 1 into the screw holes 18A and 18B of the door inner panel 6 that correspond to the screw holes 16A and 16B.
9 and tighten the nut 20 from the back side of the door inner panel 6, the escutcheon 3 is completely fixed to the door inner panel 6. Note that when the screw holes 18A and 18B are burred, the nut 20 is omitted. In the illustrated structure, the extension wall 17 is integrally molded with an elastic pawl 21 for preventing the rod 5, one end of which is engaged with the engaging portion 2a of the inside handle 2, from slipping out.
The elastic claw 21 has a barb 21a at its tip, and has an upper surface 21b, that is, a position regulating surface, located below the lower surface of the engaging portion 2a by a dimension slightly smaller than the diameter of the rod 5. When assembling,
By simply inserting one end of the rod 5 into the engaging portion in the state shown by the dashed line in Fig. 5 and rotating the rod 5 in the direction of arrow Become. A small flange 3a is formed on the outer periphery of the opening of the escutcheon 3 on the inside of the passenger compartment, and the door trim 10 is attached to the flange 3a.
The decorative frame 22 that hides the opening 10a of the nail 22a (the third,
4) (shown in the figure).

Since the above embodiment has the above structure,
When assembling the automobile door 1, after inserting the locking claws 13A, 13B of the escutcheon 3 into the mounting holes 14A, 14B, and then sliding the escutcheon 3 slightly toward the rear of the door, the escutcheon extension wall 17
screw holes 16A, 16B and door inner panel 6
screw holes 18A and 18B match, so screw 1
9 can be used to completely fix the escutcheon 3 to the door inner panel 6. After that, after attaching the door trim 10 to the door inner panel 6, the decorative frame 22 is fitted to the flange 3a of the escutcheon 3 to complete the assembly. Since the locking claws 13A and 13B are located in the small opening 14b, even if a repeated operating force is applied to the inside handle 2 as shown by the arrow in FIG. 3, the locking claws 13
A, 13B will not come off from the mounting holes 14A, 14B. Also, when the inside handle 2 is actually operated, the inside handle 2 is in the third position.
Although it may be pulled strongly downward in the figure, in the structure of the present invention, the input is supported by the screw 19 and the locking claws 13A and 13B located immediately behind the inside handle 2, so there is no need to worry about the escutcheon 3 coming off from the door inner panel. do not have.

In the above embodiment, the L-shaped locking claws 13A and 13B are bent in the vertical direction, but the locking claws may be bent in the front-rear direction of the door.

As is clear from the above description, according to the present invention, foreign objects such as screws are not present in the fingertip insertion space of the escutcheon, and since the screwed part is covered with the door trim, the appearance is good and there is no possibility of damaging the fingertip etc. A worry-free mounting structure can be provided, and since the mounting structure of the present invention is stable in its mounting state, it will not rattle or come off during use.
