Description

[Detailed Description of the Invention] The present invention relates to a door check device for regulating the opening degree of a vehicle door.

As shown in FIG. 1, the door check device generally includes a resistance arm 10 that is pivotally attached to the vehicle body (not shown) through a pivot hole 11, and the resistance arm 10 is inserted through the mounting hole 21 to attach to the door (not shown). (not shown) and a guide device 20 fixed to the side (not shown). The resistance arm 10 is made up of a pair of plates, a stopper plate 14 having a cushion 13 is fixed to the tip thereof, and a stopper plate 14 having a cushion 13 is fixed to the intermediate part thereof, and a stopper plate 14 which is bent into a convex shape to give elasticity is attached to the middle part. The above resistance section 15 is formed. The resistance portion of the resistance arm 10 may be constructed by forming unevenness on a single plate.

Guide device 20 into which the resistance arm 10 is inserted
has a basic function of regulating the maximum opening degree of the door by coming into contact with the stopper plate 14, and regulating the door opening degree in stages by means of an elastic contact member that comes into elastic contact with the resistance part 15. FIG. 2 shows an example of a conventional elastic member 22 and its support structure, in which an elastic member 24 made of a rubber material and the elastic member 22 are housed in a casing 23 with the resistance arm 10 sandwiched between them. The elastic member 22 is in elastic contact with the resistance arm 10 due to the elasticity of the elastic member 24. When the elastic contact member 22 passes through the resistance part 15, it is necessary to open the pair of elastic contact members 22 against the force of the elastic member 24 or press and displace the resistance part 15 inward.
The door opening degree is regulated by this stopper function (check force).

Conventionally, the elastic contact member 22 is made of a synthetic resin material or a sintered metal. However, although the former provides smooth operation, it does not have sufficient wear resistance, resulting in early deterioration of the check force, which is a problem in terms of durability.On the other hand, the latter has excellent wear resistance. However, the cost is high and
Further, when sliding with the resistance arm 10, there is a problem that a rough noise is generated and the operation feeling is not favorable.

The present invention solves the problems of conventional products and provides a door check device with excellent durability and low cost. , is characterized in that a slider made of a metal plate is attached to the sliding surface of the resistance arm. This slider is
It has a substantially U-shape that surrounds the elastic contact member, and both legs that follow the sliding surface with the resistance arm are slidably fitted into the casing of the guide device.

The invention will now be described with reference to the illustrated embodiments. FIG. 3 shows a first embodiment of the present invention, in which all the constituent elements other than the slider 30 are the same as those of the above-mentioned conventional example, and the same elements are given the same reference numerals. The slider 30 is made by bending a metal plate into a substantially U-shaped cross section, as shown in FIG. , covers the entire circumferential surface of the elastic member 22 except for both ends in the direction perpendicular to the plane of the drawing, and a part of the elastic member 24.
Both legs of the slider 30 following the sliding surface 31 are slidably fitted into the casing 23 of the guide device 20.

Considering the occurrence of rust, it is most preferable to use stainless steel as the metal plate constituting the slider 30, but other materials such as iron, steel, spring steel, copper, etc. can be used by applying appropriate anti-rust treatment. Is possible.

According to the main door check device having the above configuration, it is the slider 30 that comes into sliding contact with the resistance arm 10;
Since the slider 30 is made of a metal plate and has high wear resistance, it can maintain a stable checking force over a long period of time. Also, unlike sintered alloys, it does not produce abnormal noises when sliding. Further, since both legs of the slider 30 are slidably fitted into the casing 23 of the guide device 20,
Due to the sliding contact with the resistance arm 10, even if the slider 30 moves within the casing 23, the slider 30
(elastic contact member 22) is tilted within the casing 23,
Stable operation can be achieved without the risk of galling.

The elastic contact member 22 can be made of a synthetic resin material or a sintered metal as in the conventional product, and can also be made of any other material regardless of whether it is hard or soft.

FIG. 5 shows an example in which the elastic contact member 22 with the resistance arm 10 is made of a rubber material, and the slider 30 is directly attached to the sliding surface of the rubber material that comes into sliding contact with the resistance arm 10. In this example, the conventional elastic contact member 2 shown in FIG.
The slider 3 is attached to the elastic member 24 which is made larger by removing the slider 2.
In this case, the elastic member 24 constitutes an elastic member that comes into elastic contact with the resistance arm 10. This embodiment can also be expected to produce the same effects as the first embodiment.

As described above, the door check device of the present invention is a door check device in which a guide device on the door side is inserted through a resistance arm to be pivotally mounted on the vehicle body side, and an elastic member of the guide device is brought into elastic contact with the resistance arm. In the device, a slider made of a metal plate is attached to the sliding surface of the elastic contact member with the resistance arm, so the wear resistance of the slider makes it possible to obtain high durability and stable and good checking force. Since it can be formed inexpensively from a metal plate, the cost of the entire door check device can be reduced. Furthermore, the slider has a substantially U shape that surrounds the elastic contact member.
It has a letter-shaped shape, and both legs following the sliding surface with the resistance arm are slidably fitted into the casing of the guide device, making it possible to reliably slide guide the slider and elastic member. and stable sliding characteristics can be obtained.
