Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a holder cap device for a cylinder lock, in which a holder cap is assembled to the front opening of a holder that accommodates a cylinder inner that rotates in response to the operation of a key.

Conventional holder cap devices for cylinder locks include rotatably housing a cylinder inner with a lock plate that moves in and out as the key is inserted or removed in a holder, and then attaching a metal holder cap to the holder by crimping it. It is common to do something like this.

However, in such devices, the holder cap is assembled by caulking, which requires a jig and tool for caulking, making assembly difficult. Moreover, once the holder cap has been assembled, it is very difficult to disassemble it without destroying the holder cap. Therefore, in the event of poor assembly or failure, it has been difficult to repair it.

The present invention has been made in view of the above problems, and includes forming an engaging portion on the outer periphery of the holder, forming an elastic engaging portion on the holder cap that elastically engages with the engaging portion, and attaching the holder to the holder. When the cap is assembled, the holder is fitted into the mounting hole of the panel, and the cylinder lock is attached, the elastic engagement portion of the holder cap is regulated by the mounting hole and held in the engaged position, An object of the present invention is to provide a cylinder lock holder cap assembling device that improves assembling performance and can be easily disassembled and repaired.

Hereinafter, the present invention will be described in more detail with reference to the drawings.

In FIG. 1, a cylinder lock 1 is attached to a mounting hole 3 (shown in FIG. 2) formed in a panel 2 by a spring 4. 5 is a rubber gasket.

The cylinder lock 1 will be explained below in FIG.

Reference numeral 6 denotes a cylinder inner that rotates in accordance with the operation of a key (not shown), and grooves 7...7 of the cylinder inner 6.
A lock plate 8...8 is housed in the lock plate 8...8, and the lock plate 8...8 is inserted into the groove 7...7 when the key is removed.
By protruding further and engaging with the holder 12, the rotation of the cylinder inner 6 is made impossible, and when the key is inserted, the cylinder inner 6 is recessed into the grooves 7...7.
It is designed to allow for rotation. Furthermore, a washer 9 and a lever 1 are installed at the rear end of the cylinder inner 6.
0 is attached by a retaining ring 11. This lever 10 moves between the position shown by the solid line and the position shown by the dashed-dotted line in FIG. 3 in response to key operation, and locks and unlocks an automobile door lock device, although not specifically shown. There is. The holder 12 rotatably accommodates the cylinder inner 6 from the front opening 12a, and has engaging portions 13,
13 is formed. As shown in FIG. 5, the engaging parts 13, 13 include a groove-shaped recess 13a extending rearward from the front opening, and a locking part depressed toward the rear end of the groove-shaped recess 13a in the axial direction. It consists of a recessed part 13b. Reference numeral 14 denotes a holder cap having a substantially square shape on the front side. The holder cap 14 is made of a resin material and has a circular recess 15 and an opening hole 16 formed in the center thereof. Further, the holder cap 14 is provided with two elastic engagement portions 17, 17. The elastic engagement portions 17, 17 are connected to the elastic arm 17a and the elastic arm 1.
The engagement claw 17b is formed at the tip of the engagement claw 7a and protrudes in the axial direction. Further, a thin plate-shaped cylinder cover 18 is provided on the front holder cap 14 side of the cylinder inner 6, and a key insertion hole 19 is formed in the cylinder cover 18. A shutter 20 is provided to prevent rainwater, dust, etc. from entering when the key is removed.
Attach the cylinder cover 18 with the shutter spring 21.
The key insertion hole 19 is closed by pressing it against the key.

In the above structure, when assembling the holder cap 14 to the holder 12, the elastic arm 17a of the elastic engagement part 17 is formed on the engagement part 1 of the holder 12.
The engaging claw 1 is fitted into the groove-shaped recess 13a of No.3.
7b is engaged with the locking recess 13b to assemble the holder cap 14 to the holder 12. The cylinder lock 1 with the holder cap 14 assembled to the holder 12 in this manner is fitted into a mounting hole 3 formed in the door panel 2 and is mounted with a spring 4. Therefore, the elastic arm 17a of the elastic engagement part 17 formed on the holder cap 14 circumferentially contacts the mounting hole 3 and cannot be opened, so the locking recess 13b of the holder 12
The engaging pawl 17b that is engaged with will not come off. That is, the holder cap 14 is made to be easily assembled to the holder 12 by utilizing the elasticity of the resin material, and also to prevent the holder cap 14 from coming off after being installed in the mounting hole 3 of the panel 2. .

As explained above, in the present invention, an engaging part is formed on the outer periphery of the holder, a holder cap is made of a resin material, and an elastic engaging part is provided to elastically engage with the engaging part of the holder. When the holder cap is assembled into the mounting hole of the panel, the elastic engagement part of the holder cap contacts the mounting hole and is regulated by the mounting hole so that it is held in the engaged position. In addition to improving attachability, it can be easily disassembled and repaired, and serviceability can be improved. In addition, since the elastic engagement part of the holder cap is engaged with the locking recess while being fitted into the groove-shaped recess of the holder, the holder cap does not rotate relative to the holder and rotates separately. There is no need to provide a stopping means. Further, when the cylinder is attached to the panel, the holder cap is not attached in an inclined state. Further, since the holder cap is made of a resin material, it can be colored in various colors by using a coloring material, and the appearance can be improved.
