Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a door check for controlling the opening/closing force of a vehicle door and regulating the degree of opening of the vehicle door.

2. Description of the Related Art Conventionally, vehicles have been equipped with a door check in order to ensure an optimal opening/closing force when opening and closing the vehicle door and to regulate the opening degree of the vehicle door.
Typical conventional door checks are shown in FIGS. 1 to 4. Referring to FIG. 1, 1 is a vehicle body, 2 is a vehicle door rotatably attached to the body 1 by a hinge connection member 3, and a panel 4 of the vehicle body 1 and a panel 4 of the vehicle body 1 face each other when the door 2 is closed. A door check 6 is provided between the door 2 and the panel 5. 2 and 4 show enlarged sectional views of the door check 6. FIG. Note that FIG. 2 shows the door fully open, and FIG. 4 shows the door fully closed. Referring to FIGS. 2 and 4, the conventional door check 6 includes an arm 7 and a door operating force control mechanism 8, and the arm 7 extends through the door operating force control mechanism 8. One end of the arm 7 is connected to the body side plate 4, and the other end is provided with a stopper 9. Further, this arm 7 has a pair of enlarged portions 10. On the other hand, the door operation force control mechanism 8 is composed of a pair of shoes 11 arranged on both sides of the arm 7 and engaged with the arm 7, and a pair of square rubber 12 that presses these shoes 11 toward the arm 7. . Therefore, when the door 2 is opened from the state shown in FIG.
move away from each other against the elastic force of
Thus, at this time, the operating force for the door 2 temporarily increases. Next, as shown in FIG. 2, when the door 2 is fully opened, the stopper 9 of the arm 7 collides with the door operating force control mechanism 8, thereby regulating the degree of opening of the door 2.

As can be seen from FIGS. 2 and 3, in the door operating force control mechanism 8 of the conventional door check 6, a shoe 11 is arranged that contacts only the flat surfaces on both sides of the arm 7, and the arm 7 does not move in a horizontal plane when opening or closing the door. In order to rotate slightly relative to the door operation force control mechanism 8, each shoe 11 has a triangular cross-sectional shape. However, when such a door check 6 is used for a long time, the grease between the arm 7 and the shoe 11 runs out, causing a problem in that sliding noise is generated when the door is opened and closed.

The object of the present invention is to provide a door check that does not generate sliding noise even when used for a long time.

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

5 to 7, the same components as in FIGS. 1 to 4 are designated by the same reference numerals. Referring to FIGS. 5 to 7, the door check 20 according to the present invention is composed of an arm 21 made of a pair of polymer strip-shaped plates and a door operating force control mechanism 22. It extends through the mechanism 22 . Body 1 panel 4
A bracket 23 is fixed on the top, and one end of the arm 21 is pivotally connected to the bracket 23 via a pin 24. On the other hand, the arm 21 has a stopper 25 at the other end, and an enlarged part 2 at the middle part.
It has 1a. This stopper 25 consists of an abutting member 26 made of a rubber material and a retainer 27 that supports this abutting member 26, and this retainer 27 is prevented from coming off by a pin 28 passing through the arm 21. The door operation force control mechanism 22 is composed of a housing 29 and an end plate 30, and the housing 29 and the end plate 30 are fixed to the panel 5 of the door 2 with a nut 31. housing 2
Apertures 32 and 32' are formed on the end plate 9 and the end plate 30, respectively, through which the enlarged portion 21a of the arm 21 can pass, and furthermore, on the end plate 30, rainwater etc. are prevented from entering into the aperture 32. An elastic seal member 33 is attached for this purpose.

As shown in FIGS. 5 and 8, the housing 22 has a hollow cylindrical housing portion 22a, and a pair of sleeves 34, 35 are provided inside the housing portion 22a, and a pair of sleeves 34, 35 surrounding the sleeves 34, 35 are provided inside the housing portion 22a. an elastic member 36 made of rubber material;
37 is inserted. The pair of sleeves 34, 35 has a shape similar to that of a cylindrical member with a rectangular cross section divided into two, and therefore, as shown in FIG. 8, the opposing end surfaces of each sleeve 34, 35 are in contact with each other. When the sleeves 34 and 35 are in place, an arm insertion cross section approximately equal to the cross-sectional shape of the arm 21 is formed between the sleeves 34 and 35 over the entire length of the sleeves 34 and 35. As shown in FIGS. 9 to 12, each sleeve 34, 35 has semicircular flanges 38, 39, 40, 41 at its upper and lower ends that cover the inner edges of the upper and lower surfaces of the elastic members 36, 37. is formed. Note that each of these sleeves 34 and 35 can also be adhered to the elastic members 36 and 37 using an adhesive. Furthermore, as shown in FIGS. 5, 8, and 9, a grease reservoir 42 is formed on the inner wall surface of the sleeve 35 and extends in the axial direction of the arm 21. On the other hand, the elastic members 36 and 37 have a shape like a cylindrical member divided into two, and the outer peripheral surfaces of these elastic members 36 and 37 are connected to the cylindrical housing portion 22.
The elastic members 36, 37 are in contact with the inner wall surface of a.
The inner circumferential surfaces of the sleeves 34 and 35 contact the outer circumferential surfaces of the sleeves 34 and 35. In addition, as shown in FIG. 8, each elastic member 36,
Both ends of the opposing end surfaces of each elastic member 36, 37 are cut off obliquely so that wedge-shaped spaces 43, 44 are formed at both ends of the opposing end surface when the opposing end surfaces of the elastic members 37 are in contact with each other.

According to the present invention, the arm insertion cross section defined by the inner circumferential wall surfaces of the sleeves 34 and 35 is
A grease reservoir 42 is formed on the inner circumferential wall surface of the sleeve 35 by forming the entire length of the sleeves 4 and 35 to be approximately equal in cross-sectional shape to the arm 21, thereby forming a grease reservoir 42 that can continue to supply grease between the arm 21 and the sleeves 34 and 35. can do. As a result, it is possible not only to prevent the sleeves 34 and 35 from being worn out due to the sliding movement of the arm 21, but also to prevent the generation of sliding noise when the door is opened and closed.
