Japanese Patent Laid-Open No. 10-140911 JP 2003-155860 A

As described above, in the above two cases, the upper and lower surfaces of the arm (lever) are pushed to stop the door at a required position, the structure is complicated, and the roller and the cylindrical body are pressed. It is adjusted with a bolt (screw member) or with a spring.
However, adjusting with a bolt or the like is actually difficult, and since it is controlled by a motor, the cost is high and there is a problem in practical use.

  Further, even in the case of using a spring, the upper and lower surfaces are pressed, and surface contact is made. Therefore, it is difficult to stop the door at an arbitrary position, and there is a case where it returns.

  The present invention is intended to solve the problems of such a conventional configuration. The side surface of the stay taper portion provided at the rear portion of the door checker stay, particularly the plunger in the pressing tool is raised. An object of the present invention is to provide a door checker holder that can stop a door at an arbitrary position by pressing with a high-viscosity rubber with a point and a surface.

  In order to achieve the above object, the present invention is a flat plate formed on a vehicle body by a checker support pin so as to be rotatable, a stay parallel portion is formed at the front portion, and the engagement projecting to one side near the center portion. A stay checker with a stop is formed, and a stay taper that extends toward the rear is formed integrally with the door checker stay, and the door checker stay is provided in the door that holds both side surfaces of the door checker stay. It consists of a pressing tool. Moreover, the pressing tool was comprised from the rotating roller and the plunger which controls the entrance / exit of a press part. In addition, the plunger must be silicon rubber. Furthermore, the rotating roller and the plunger should be provided at positions facing each other, and an appropriate gap should be provided between one side surface of the door checker and the pressing portion with the door closed. The pressing part is a steel ball, the pressing part is point contact with the side surface of the door checker stay, and the rotating roller is line contact. When the door is opened, the shaft center of the door checker stay and the shaft centers of the rotating roller and the pressing tool are not right angles but slightly changed.

1) In the door checker stay, by integrally forming the stay parallel part, stay projection part, and stay taper part with a flat plate, the stay projection part can be temporarily stopped and at any position in the stay taper part The door can be surely stopped.
2) Due to the stay taper, the door can be closed smoothly without load.
3) The door checker stay is formed by punching a flat plate, can be processed at a low cost, and has no uneven processing on the upper and lower surfaces as in the conventional product, so the processing accuracy is high.
4) By holding the side surface of the door checker stay with the pressing tool (rotating roller and plunger) while keeping the axis of the rotating roller and plunger slightly eccentric from the right angle with respect to the axis of the door checker stay, The door can be surely stopped.
5) By using silicone rubber (high viscosity, high tension rubber) as the plunger in the pressing tool, the pressing force gradually increases in response to the inclination of the stay taper, and the coil hits like a spring and stops operation. It is rare to become.
6) By setting the pressing portion to point contact and pressing the rotating roller by line contact, the door can be more reliably stopped at an arbitrary position as compared with the conventional technique.

Embodiments of the present invention will be described below in detail with reference to the drawings.
The door checker holder 1 includes a door checker stay 2 and a pressing tool 3.
First, the door checker stay 2 is provided on the vehicle body so as to be automatically rotatable by a checker support pin. The door checker stay 2 is flat and has a pin hole 2a1 at the front end, a support collar 2a2 at the top and bottom, and both sides are parallel. The stay parallel part 2a formed in the above and the stay projection part 2b provided with the locking part 2b1 projecting in a mountain shape from one side in the vicinity of the central part are formed, and the rear part along the locking part 2b1 The stay taper portions 2c each having a fixing pin 2c1 provided at the rear end are integrally provided.
Next, the pressing tool 3 holds both side surfaces of the door checker stay 2, and is installed in the center of the holding tool main body 3a provided with bolt holes 3a1 and 3a1 to be attached to the door by the roller cover 3b1. The rotary roller 3b is supported, and the plunger 3c is composed of a pressing tool 3c2 made of silicon rubber that controls the entry and exit of the pressing part 3c1 made of steel balls at opposite positions.

Next, the operation of the door checker holder 1 having the above configuration will be described.
First, the pin hole 2a1 at the tip of the door checker stay 2 and the support collar are connected and fixed to a U-shaped bracket (door hinge) K provided in the door-side body (door frame) DB with a pin P.
Next, the pressing tool 3 is attached to the inside of the door D with a bolt (not shown).
At this time, the rotation roller 3b is in contact with one side surface of the door checker stay 2, and the other side surface and the pressing portion 3c1 are not in contact with each other, and a slight gap S is provided.
And it fixes to the required position of the door D with the fixing pin 2c1 of the door checker stay 2. FIG.

When the door D is opened in this state, the pressing portion 3c1 starts to hit the side surface of the door checker stay 2, and can be temporarily locked when the rotating roller 3b rides on the locking portion 2b1. (At this time, the pressing tool 3c2 made of silicon rubber is appropriately compressed and locked by its reaction force.)
Subsequently, when the door D is opened more widely, the rotary roller 3b moves along the stay taper portion 2c, whereby the pressing tool 3c2 is gradually pressed, and the rotary roller 3b with respect to the axis of the door checker stay 2 Further, by changing the axis of the plunger 3c slightly from the right angle, the fulcrum to be held is changed, and the door D can be stopped at an arbitrary position on the stay taper portion 2c.

In the above-described embodiments, silicon rubber is a kind of high-viscosity high-tensile rubber, and it is conceivable to use other rubber as long as it has a similar function.
Further, the pressing tool holds both side surfaces of the door checker stay, and other structures may be considered if they have similar functions.
