Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to a vehicle door checker that facilitates door opening/closing operations.

[Technical background of the invention and its problems]

The front door and rear door of an automobile are rotatably supported on the vehicle body side, that is, the pillar, via door hinges. A door checker is provided near the door hinge to apply a brake when the door is opened or closed, so that the door opens and closes smoothly while maintaining a desired resistance.

By the way, a conventional door checker is constructed as shown in FIGS. 4 and 5. That is,
1 is a vehicle body, and 2 is a pillar. A door 4 is pivotally supported on the pillar 2 via a door hinge 3 so as to be openable and closable. Furthermore, 5 is an arm of a door checker 6, and this arm 5 is rotatably supported on the pillar 2 by a pin 7. This arm 5 is composed of a thin wall portion 5a and a thick wall portion 5b, and its tip portion extends in the direction of the end surface of the door 4. On the other hand, the door 4 is composed of a door inner 4a and a door outer 4b, and an opening 8 is formed in the end surface of the door inner 4a. A bracket 9 of a door checker 6 is fixed to this opening 8, and a damper 1 is installed inside this bracket 9.
A pair of sliders 11 and 11 are provided facing each other with 0 and 10 interposed therebetween. These sliders 11, 11 are urged in the direction of approaching each other by dampers 10, 10.
The tip of the arm 5 is interposed between and 11. A stopper 13 is fixed to the tip of the arm 5 via a cushion 12.

When the door 4 is rotated about the door hinge 3, the arm 5 moves back and forth between the sliders 11 and 11.
The opening and closing of the door 4 is braked by the pressing force on the arm 5. In other words, the thin wall portion 5a of the arm 5 provides a weak braking force, and the thick wall portion 5b provides a strong braking force, both of which apply braking force to the opening and closing of the door 4 due to the frictional force between the arm 5 and the slider 11. Therefore, as the check force increases, the force for opening and closing the door increases, which is very difficult to adjust, and there are disadvantages in that the force for opening and closing the door 4 changes as the damper 10 changes over time.

(Purpose of the invention) This invention was made by paying attention to the above-mentioned circumstances, and its purpose is to enable the brake to be released by operating the door handle, and to open and close the door smoothly and easily. Moreover, it is an object of the present invention to provide a door checker for a vehicle that can improve durability.

[Summary of the idea]

In order to achieve the above object, this invention includes a bracket having a through hole through which an arm protruding from the vehicle body can move forward and backward; a rotating lever biased by the door handle; and an operating member that is interlocked with the door handle and rotates the rotating lever against the biasing force when the door is operated, thereby releasing the pressing force on the arm. The braking force can be released by the operation.

[Example of idea]

An embodiment of this invention will be described below based on the drawings.

In FIGS. 1 to 3, 21 is a vehicle body, that is, a pillar, and 22 is a door. An arm 23 is rotatably supported on the pillar 21 via a pin. This arm 23 has a thin part 23a and a thick part 23.
b, and this tip extends in the direction of the end face of the door 22. An opening 25 is formed in the door inner 24 of the door 22, and the opening 25 is closed by a bracket 26 which is fastened to the door inner 24. This bracket 26 has a rectangular plate shape, and a through hole 27 is bored approximately in the center thereof. and,
The arm 23 is inserted into this through hole 27,
A receiving portion 28 having approximately the same width as the arm 23 is bent at the lower edge of the through hole 27 . Further, a rotary lever 30 is rotatably supported on the bracket 26 by a pin 29. The upper end of a spring 31 is hooked to one end of the rotating lever 30, and the lower end of the spring 31 is hooked to a spring receiver 32 provided at the bottom of the bracket 26. The rotary lever 30 is urged in the direction of arrow a. Furthermore, a presser portion 33 consisting of a bent portion facing the receiving portion 28 is provided on the biasing direction side of the rotating lever 30, and the arm 23 is interposed between the presser portion 33 and the receiving portion 28. has been done. A cushion 34 is attached to the tip of this arm 23.
is fixed by a stopper 35. Also,
A projection 26a is provided on a part of the bracket 26 to restrict the rotation range of the rotation lever 30, and the distance between the receiving portion 28 and the holding portion 33 is made wider than the thin wall portion 23a of the arm 23. . A connecting portion 36 is provided at the other end of the rotating lever 30 formed in this manner, and one end portion of a cable 37 serving as an operating member is connected to this connecting portion 34. This cable 37 is connected to a door handle 38 provided on the outside of the door 22. Further, the connecting portion 36 is also connected to a doorknob 39 on the inside of the door 22. When either the door handle 38 or the door knob 39 is operated, a rotation force is applied to the rotation lever 30 via the connecting portion 36 in the direction of arrow b, that is, in the opposite direction to the biasing direction of the spring 31. ing.

Next, the operation of the above embodiment will be explained.

First, when the door 22 is closed, the rotating lever 30 is rotated in the direction of arrow a by the biasing force of the spring 31. Therefore,
The arm 23 is held between a receiving part 28 and a holding part 33. When the door handle 38 is operated to open the door 22 from this state, the cable 37
is pulled, and the rotating lever 30 rotates in the direction of arrow b via the connecting portion 36 against the biasing force of the spring 31. Therefore, the presser portion 33 separates from the arm 23, and the brake on the arm 23 is released. In this way, when the brake on the arm 23 is released by operating the door handle 38, the door 22 can be opened with a small operating force, and the door 22 can be opened and closed smoothly. Note that the same applies when the doorknob 39 is operated. moreover,
Since the rotation range of the rotation lever 30 is restricted by the protrusion 26a, the thin wall portion 23a of the arm 23
When the arm 23 passes between the receiving part 28 and the holding part 33, no braking is applied to the arm 23. Therefore, when the degree of opening of the door 22 is small, the door 22 can be smoothly opened and closed without rotating the rotating lever 30.

[Effect of idea]

As explained above, according to this invention, there is provided a bracket having a through hole through which an arm protruding from the vehicle body can move forward and backward, and a bracket rotatably supported on the bracket in a direction in which braking is applied to the arm. a rotating lever biased by the door handle; and an operating member that is interlocked with the door handle and rotates the rotating lever against the biasing force when the door is operated, thereby releasing the pressing force on the arm. Since the braking force can be released by the operation of play.
