Problems solved by technology

[0005] In conventional door stoppers for automobiles, since a space allowing elastic deformation of the elastic member is provided between the outer surface of the elastic member and the inner surface of the housing, rainwater may infiltrate into the space along the restricting plate or the like, and Once the rainwater freezes, the elastic deformation characteristics of the elastic parts will change, which will cause the unsmooth operation of the door switch
[0006] Therefore, there is also a method of covering the casing and the limiting plate with a waterproof cover to prevent rainwater from penetrating into the casing, but even with this structure, the casing cannot be completely waterproofed, and the number of parts increases, resulting in high cost.

Embodiment 1

[0045] first, figure 1 Among them, a door D for opening and closing a landing is rotatably attached to a body B of an automobile through a hinge H, and a door stopper C of the present invention is installed between the body B and the door D.

[0046] Such as Figure 1 to Figure 4 As shown, the above-mentioned door stopper C has a housing 1 fastened to the inner surface of the end wall of the door D. As shown in FIG. The housing 1 includes: a box-shaped housing main body 1a with one end open; Figure 4 ) is combined with the housing main body 1a, so that the cover 1b abuts against the inner surface of the end wall of the door D, so that the housing main body 1a and the cover 1b are fastened to the end of the door D by a pair of upper and lower bolts 2, 2 on the wall. Through-holes 4, 5 are perforated on the cover 1b and the housing main body 1a. The through-holes 4, 5 are arranged coaxially with the through-hole 3 opened on the end wall of the door D, and pass through the th...

Embodiment 2

[0062] next, yes Image 6 A second embodiment of the present invention is shown and described.

[0063] This embodiment is the same as the previous embodiment except that the hard portion 17h of each elastic member 17 is provided with a concave portion 20 closed by the inner end surface 18b of the housing 1 or the outer end surface 18a of the stopper member 16. structure, therefore, the Image 6 Parts corresponding to those in the previous embodiment are marked with the same reference symbols, and repeated explanations are omitted.

[0064] According to this embodiment, the elastic deformation characteristic of the hard portion 17h of the elastic member 17 can be freely adjusted by the volume of the recessed portion 20 provided thereon. Moreover, since the recess 20 is closed by the inner end surface 18b of the housing 1 or the outer end surface 18a of the stopper member 16, it is possible to prevent rainwater from penetrating into the recess 20 in a simple manner, so that t...

Abstract

A door checker for an automobile, comprising a case (1) fixed to a door (D), a check plate (6) pivotally supported, at its base end, on a body (B) and movably passed through the case (1), detent members (16) fittedly held on the case (1) and operating in cooperation with the detent surfaces (10) of the check plate (6), and elastic material-make spring members (17) installed, in a contracted state, in storage chambers (18) formed between the outer end surfaces (18a) of the detent members (16) and the inner end surfaces (18b) of the case (1). The spring member (17) is substantially densely filled in the storage chamber (18) so that rain water does not enter the storage chamber (18). Thus, the entry of rain water into the storage chambers of the case storing the spring members can be prevented from occurring by a simple structure.

Description

technical field [0001] The present invention relates to improvements in door stoppers for automobiles. Background technique [0002] A door stopper for an automobile has a casing fastened to one of a body of the automobile and a door rotatably supported on the body; a restriction plate passing through the casing in a movable manner and connected to On the other side of the vehicle body and the door; a stop member, which is slidably fitted and held in the housing, and cooperates with the stop surface of the limiting plate to hold the door at a predetermined open position; elastic An elastic member made of material, which is compressed and arranged in the accommodation chamber formed between the outer end surface of the stopper member on the opposite side to the restriction plate and the inner end surface of the housing facing the outer end surface, so as to A stopping force is generated between the above-mentioned stopping member and the stopping surface. [0003] A related...
