Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a key cylinder equipped with a heavy-duty opening/closing body.
= Regarding J structure.

If the conventional structure of this cutting-cylinder is explained based on the sight door 2 of the automatic type 1 as shown in Fig. 1 and Fig. The door outer panel 3 has a mounting hole 6 for a key cylinder 5. Then, the key cylinder 5 is fitted into the mounting hole 6 from the outside of the side door 2, and the tip flange 7 of the key cylinder 5 is brought into contact with the periphery of the mounting hole 6 via the sealing washer 8. Press fit the leaf spring-like glue tening clip 11 from the inside of the door outer panel 3 into the two claws 1o protruding from the body 9 of the door outer panel 3.
I had set up an IM. In addition, 12 is a key cylinder lever, which is connected to the locking lever of the toro-ring device outside of FIG.

Then, when a key plate (not shown) is inserted into the key cylinder 5 and rotated, the key cylinder stagnation/
<-12 rotates, and the aforementioned Ronking lever operates to unlock and lock the side 1 core 2.

In addition, 14 in the figure indicates the pillar panel 15 when the side door 2 is closed.
This is a door weather strip that provides an elastic seal.

1-However, in such a conventional supplementary structure, since the rigidity of the key ring 5's convenient part with respect to the door outer panel 3 is relatively small, the key ring 5 is subject to some kind of unauthorized M-lock manual force other than key operation. If this occurs, the door outer panel 31'! It was thought that the key ring 5 would be tilted due to deformation of the body, and there was a problem in terms of theft prevention.

The present invention has been made to solve these problems, and its purpose is to prevent the top of the key ring from being removed when manual unlocking is applied to the key ring. The purpose of the present invention is to reliably prevent horn ties, tilts, and inclinations in the direction, and to provide a key phrase structure that is effective in preventing theft in the city. The place to do this is the door outer panel and inner panel.
[While forming the opening/closing body for A, open a key ring hole in the outer pawl described in 1-, and fix the key ring inserted into the hole in the outer panel.
・The indoor end of the key ring is supported by two langes formed on the inner panel.

Hereinafter, the unreleased I51 will be explained in detail based on the embodiment shown in the accompanying drawings.

In the first embodiment of the present invention shown in FIGS. 3 and 4, the key ring 5 is fixed to the door outer panel 3 via the retaining crimp 11 as in the conventional case, but unlike the conventional case, the key ring 5 is 5 is supported by a flange 16 formed as a part of the door inner panel 4. As shown in FIG. The inner circumferential surface 17 is formed in a curved shape so that it can be held all the way to the end.

The JL fledge 16 is formed by cutting and bending a part of the door inner panel 4, so it has a relatively rigid structure and is easier to form than welding separate pieces. The means are easy.

Therefore, according to the additional edition structure of the key ring 5 described in 1-, the tip part of the key ring 5 is fixed to the door outer panel 3, and at the same time, the rear end part is also supported by the flange 16 formed on the door inner panel 4. Since the movement is restricted, for example, even if a manual force to unlock the key is applied to the key ring 5 and the key ring 5 is tilted in the opposite direction to try to open it, the curved inner periphery of the flange 16 marked 1. Surface 17
The outer circumferential surface of the 111 part 9 of the key ring 5 comes into contact with the key ring 5, preventing the key ring 5 from bending in the 1-to direction. Since the rigidity is high, the flange 16 itself will not bend, and the key ring 5
The tilting movement of the key ring 5 of the door outer knob 3 can be prevented from deformation at the same time.

5 and 6 show an attachment structure for the key ring 19 mounted on the handle 18. FIG.

Similarly to the previous embodiment, the key ring 19 in this embodiment has its tip fixed to the bank door outer panel 20 via a retaining clip 22, and its rear end supported by a flange 23 formed on the back door inner panel 21. However, unlike the previous embodiment, the key seal ring I9 is attached to the attachment portion on the henk door outer panel 20 side.

A flange-shaped reinforcing portion 24 is provided that integrally extends from the inner panel 2I.

In this embodiment, a part of the back door inner panel 21 is raised to the side of the bank door outer panel 20 to form a working hole 25, and a cut-out piece 26 extending from the edge of the working hole 25 is formed. The tip part is bent downward on the back side of the hecktore outer panel 20 to form a flange-shaped reinforcement part 2.
4, and the flange 23 is formed by cutting and raising the rear end portion of the key cylinder of the cut-and-raised piece 26 toward the key cylinder 19 side. The reinforcement part 24
As shown in FIG. 6, the body 27 of the key ring 18
The flange 23 extends in a bifurcated manner on both sides, and the inner circumferential surface 2 of the flange 23 is curved so that it can be held along the upper outer periphery of the body 27 to the left side A, as in the previous embodiment. 4. In Figure 5, mark 528 is Turin which hides the working hole 25.
The cover 30 is a weather strip that is fastened along one end flange 32 of the door handle 18 to attach the window glass 31.

Therefore, according to this embodiment, the key cylinder 19 is connected to the reinforcing portion 24 extending from the rear side of the bank door outer panel 20/the pulley inner panel 21;
With the reinforcing part 24 sandwiched in, the retaining clip 22 is set at 1 (-entering circle>l), and at the same time, the rear end is also set at 1-
The furan formed on the record 21;;'
Supported by 23)-v.

Therefore, in addition to being able to further improve the closing +1 of the attachment site on the M7/X-/Riji Aukbanel 20 side,
It is possible to reliably prevent the key cylinder 19 from tilting in the horizontal direction when a manual force for unlocking the key cylinder 19 is applied, and from tilting the key cylinder 19 due to deformation of the puncture outer knob 20.

In each of the above embodiments, one side of the outer peripheral surface of the key cylinder is supported by a flange, but it is of course possible to extend the flange around the entire outer peripheral surface. The same applies to the reinforcing part.

Further, in each of the above embodiments, a sliding type door has been described as an opening/closing body, but the present invention can also be applied to a key cylinder mounting structure of a trunk lint.

Theory 1. As mentioned above, the key cylinder according to the present invention (=1 according to the structure, the lock Pf?
Since the movement of the key cylinder in the unlocking direction in response to a lock input can be reliably performed as fiLl, tl=, this particularly improves theft prevention.
