Description

[Detailed Description of the Invention] The present invention relates to a protector for a door lock of an automobile, and more particularly to a protector for a door lock that prevents the door lock from being released because the door lock knob cannot be touched even if a wire or the like is inserted through the gap in the door outside handle. .

Conventionally, a knob-type door lock device equipped with a door lock knob that slides vertically to lock and unlock the door has been used on the road because it is easier to unlock the door from the outside compared to a lever-type door lock device. There was a risk of theft. In particular, if the gap C of the door outside handle 1 is larger than the specified size as shown in Figure 1, insert a wire 2 or the like through the core gap and push up the lower neck 3a of the door lock knob 3 with its tip 2a to release the door lock. In some cases, it was possible to do so, and there was room for improvement.

In addition, in Utility Model Application No. 57-33871, a box body and a flange part are integrated, which form a tongue piece with locking grooves on both sides to cover the connecting part between the lock knob and the link member, that is, the lower part of the neck of the lock knob. This is an indoor locking device for a vehicle door that uses a holder formed in a holder to prevent the wire from reaching the lower part of the neck of the lock knob even if a wire is inserted through the gap between the outside handle of the door or the sealing weather strip. However, in the conventional example, since the flange portion and the box body are integrally formed, the lower exit portion of each of the locking grooves of the pair of tongue pieces has an upward slope of about 45°. Although it has a suitable holding force against the inner plate member, if a strong force is applied from below with a wire or the like, the tongue piece will be pushed up relatively easily and the entire holder will be pushed away from the inner plate member. There is a risk that the lock knob may come off, and that it may be damaged.In any case, there is a risk that the lock knob may be removed from the outside and the door may be opened illegally, resulting in theft, so there is room for improvement.

The present invention was devised to eliminate the above-mentioned drawbacks of the prior art, and its purpose is that even in a knob-type door lock device, even if a wire is inserted through the gap in the door outside handle, it will not be possible to lock the door under the neck of the door lock knob. To prevent theft on the street by covering the door with a protector case so that the door cannot be touched.
Another purpose is to divide the door lock protector into two parts, the door lock knob cover and the protector case, so that during assembly, the pair of hooks on the door lock knob cover can touch the pair of claws on the protector case in the left and right direction. By expanding the hook part itself, in addition to the locking force of the hook part itself against the inner panel, as the hook part continues to press the pair of claw parts, the upper end of the claw part comes into contact with the lower surface of the inner panel. No matter how strongly you push up the protector case from below with a wire, etc., the protector case will never come off from the inner panel, and the protector case will never be damaged. To completely prevent vehicle doors from being opened from the outside and being stolen. Another object of the present invention is to facilitate the assembly work without changing the conventional door assembly procedure and parts used.

In short, the present invention provides a knob-type door lock device equipped with a door lock knob that slides vertically to lock and unlock the door. A claw part is formed, a flange part is formed at the upper part to be set on the inner panel of the door, and a bottom part is formed at the lower part with a small hole for penetrating the door lock which is integrated with the door lock knob, and the inner panel A protector case is attached inside the door lock knob to cover the lower part of the neck of the door lock knob, and a pair of elastic hook parts are formed to protrude downward to be locked to the inner panel when moving upward. and a door lock knob cover formed with a cover portion into which the door lock knob is fitted integrally with the hook portion, the protector case is embedded in the inner panel, and the hook of the door lock knob cover is provided. The protector case is characterized in that the claw portion of the protector case is expanded to be engaged with the lower surface of the inner panel.

The present invention will be explained below based on embodiments shown in the drawings. 2 to 6, the door lock protector 4 according to the present invention is a knob type door lock protector 4 equipped with a door lock knob 3 that slides vertically to lock and unlock the door 5 (see FIG. 1). This door lock device 6 is equipped with a protector case 8 and a door lock knob cover 9.

The protector case 8 has a pair of claws 8b, 8b formed on both side surfaces 8a, 8a, respectively, which can be expanded outward from the side surfaces, and has an upper portion configured to be set on the inner panel 10 of the door 5. A bottom part 8e is formed with a small hole 8d for penetrating the door lock 11 integral with the door lock knob 3, and is attached to the inner panel 5 to form a flange part 8c at the bottom of the neck of the door lock knob 3. It is designed to cover 3a.

The door lock knob cover 9 is formed with a pair of elastic hook portions 9a, 9a which are sharply formed downward and are engaged with the lower surface 10a of the inner panel 10 when moving upward. A cover part 9c is formed integrally with the hook part and has a hole 9b into which the door lock knob 3 is inserted.

Then, attach the protector case 8 to the inner panel 10.
The hook portion 9a of the door lock knob cover 9 is embedded in the inner panel 10 so that the claw portion 8b of the protector case 8 is expanded to be engaged with the lower surface 10a of the inner panel 10. Further, after the door lock protector 4 is assembled in this manner, door trims (not shown) and the like are sequentially assembled.

The present invention is constructed as described above, and its operation will be explained below. As shown in FIG. 6, when the door lock protector 4 of the present invention is attached, even if the wire 2 is inserted through the gap C of the door outside handle 1 as shown in FIG. case 8
The door cannot reach the bottom part 8e of the door lock knob 3, and cannot reach the bottom part 3a of the door lock knob 3. Therefore, even if an attempt is made to illegally unlock the door from the outside as in the prior art, it becomes impossible, and theft on the road is prevented.

Also, the assembly process is as simple as inserting the protector case 8 and door lock knob cover 9.
It can be easily performed without any need to change conventional procedures or parts used.

Since the present invention is constructed and operates as described above, even in a knob-type door lock device, a protector case is provided so that even if a wire is inserted through the gap in the door outside handle, the lower part of the neck of the door lock knob cannot be touched. Since the door lock is covered with a rubber band, the door lock cannot be illegally released, and the effect of preventing theft on the road can be obtained. In addition, as a result of dividing the door lock protector into two parts, the door lock knob cover and the protector case, the pair of hooks on the door lock knob cover will cause the pair of claws on the protector case to expand in the left and right direction during assembly. Therefore, in addition to the locking force of the hook itself to the inner panel, the hook continues to push the pair of claws, so the upper end of the claw comes into contact with the lower surface of the inner panel and gets caught. No matter how forcefully you push up the protector case from below with a wire, etc., the protector case will never come off from the inner panel.
Furthermore, since the protector case is not damaged, it is possible to completely prevent the vehicle door from being illegally opened from the outside and theft. Further, there is an advantage that the assembly work can be easily performed without changing the conventional door assembly procedure or parts used.
