Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a connecting rod structure for an automobile door lock device IM.

In general, in automobile 14, the linkage that connects the door lock mechanism and the inside handle tends to be longer when the door lock is arranged differently, such as in a two-door car or a wagon table. Vibrations while driving and mechanical shock when closing the door can cause the inner wall inside the door panel to come into contact with the linkage, producing chattering or rattling noises.In this way, contact noise caused by vibrations, etc. when closing the door can be eliminated. As a countermeasure against this, a technique is known in which an elastic member such as a sponge is interposed between the linkage and the inner wall of the door panel, as disclosed in, for example, Japanese Utility Model Publication No. 48-40271.

However, although the above-mentioned elastic member can prevent contact noise due to vibration, etc., it has the disadvantage that frictional resistance increases because it is made of a material such as sponge, and operation resistance due to the linkage increases.

In addition, if the linkage on the structure is installed in an offset state, when the linkage is operated, the part of the linkage will extend in a straight line so as to hide the distance between the tiles, causing a stroke cross phenomenon. As a means to prevent this, the middle part of the linkage is brought into contact with the door panel, and this contact part is used as a guide means. However, as a result of this, when operating the door lock lI411, 1
The linkage caused a clicking sound and a grinding feeling when sliding, which made JljlK uncomfortable.

This invention was devised in view of such conventional problems, and provides an automobile door that effectively prevents the knocking sound of the linkage when the automobile is running, and improves the operability of the linkage. This provides a connecting rod structure for a locking device.

In order to achieve the above-mentioned object, this invention includes a hard outer cylinder in advance in the middle of the linkage connecting the door lock mechanism and the operating mechanism or between the operating knob and the operating handle or knobs. The gist is that the cylinder is constructed by fitting a soft double-structured cylindrical loosening hook member into the cylinder.

Hereinafter, the present invention will be described in detail based on the accompanying drawings.

Figure 1 shows a front door 3 that is not equipped with a vehicle body IK center pillar and is swingably attached to the vehicle body IK.
This shows a one-box car equipped with a rear door 3b that is slidably attached to the vehicle body IK. As shown, the striker 5 attached to the car body 1,
A door lock mechanism 9, 9b consisting of a latch mechanism 7 attached to the door support is provided. The door lock mechanisms 9m and 9b are connected to the operating mechanism 11 through a linkage ISK provided inside the door sash 11 and the door spring 1s, and the operating mechanism 17 is connected to the door inside handle 21 and the door inside lock knob via a linkage 19. 211 etc. Linkage 15 connecting door lock mechanism 91 and operating mechanism 17
As shown in Section 4 (2) and BS, there is a double cylinder in the middle of which is a hard outer cylinder 23 made of solid rubber or the like and a soft cylinder 25 made of sponge rubber or the like inside. The structure consists of a cylindrical lI# member with four inserts.

This simple hook $1 $27 is made in advance before attaching the linkage III to the latch mechanism 7 and the operating mechanism 17.
From one end of the lino cage IS to the middle - self-insert it into a cylindrical shape. This prevents the loose ball material 27 from moving. Reference numeral 29 denotes a washer interposed between the upper end of the cylindrical relaxation member 27 and the crushed portions 15a and 15b of the linkage 15. It has the function of a stopper to prevent the cylindrical loose member 27 from shifting during installation and insertion.

Note that the above embodiment is based on the latch mechanism 7 of the 7μ seat door 3a.
r4 only on the linkage 15 that connects the and operating mechanism 17.
Although we have described the case where the UN member 27 is installed in the same way, the linkage 19 connecting the operation@@17 and the locking/unlocking door inside lock knob 21m or the sliding door of the vehicle not shown in the linkage 19 or 3, Of course, it can also be applied to backdoor linkage.

As described above, this invention provides a linkage that connects the door lock mechanism and the operating mechanism, and a linkage that connects the operating mechanism and the operating handle and knobs. Since the heavy-duty cylindrical edge 1lls material is interposed, it is possible to effectively prevent the generation of the rattling and rattling sounds that occur when the linkage contacts the door sash or door panel due to vibrations when the car is running. Furthermore, since the cylindrical loose member has a double structure made of two types of materials with different hardness, the contact friction resistance between the linkage and the cylindrical edge material is small, and the door lock release operation can be significantly improved.

Even more cylindrical! Since the III material is installed in the middle of the longitudinal direction of the linkage and is configured so that it does not come into constant contact with the door panel or door sash, rainwater, etc. does not travel through the linkage and flow into the operating mechanism or locking mechanism. It is highly effective in preventing rust and freezing.
