Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automobile door checking device that applies a required checking force to maintain the door opening angle at an arbitrary position when opening and closing the automobile door.

As shown in FIGS. 1 and 2, the conventional door check device has a bulge A1 approximately at the center in the longitudinal direction.
One end of arm A, which has a shape of The upper and lower surfaces are clamped by a slider G attached to the door E side and urged toward the upper and lower surfaces of the arm A by an elastic body F, so that the arm A and the slider are moved when the door is opened and closed. When the slider G moves relative to the longitudinal direction of the arm A, the slider G is positioned on the bulge A1 of the arm A, so that a required resistance force is applied, and the required resistance is applied to opening and closing the door, and the opening angle of the door is adjusted. It is designed to be held in any position.

However, in the conventional device as described above, the required resistance force for opening and closing the door is applied by relative movement of the arm A and the slider G in the longitudinal direction of the arm A. Therefore, the arm A has an expansion force. The exit A1 becomes essential. Further, this bulging portion A1 must have a structure that does not bend even when the pressing force of the elastic body F is applied, which has the drawback of complicating the structure and reducing productivity. Furthermore, since the axis D, which is the rotational axis of the arm A, and the hinge axis B of the door hinge are eccentric, the arm A and the slider G move relative to each other in the longitudinal direction and the width direction of the vehicle body when the door is opened and closed. do. This movement in the width direction of the vehicle body causes arm A to oscillate laterally, and the other end may come into contact with the windshield or inner panel, causing abnormal noise. In order to prevent this arm A from lateral vibration, it is conceivable to provide the slider G with a lateral vibration prevention protrusion that can come into contact with both side edges of the arm A. A clearance is required between both side edges of the door to absorb the relative movement of arm A and slider G in the vehicle width direction as the door opens and closes.
There is a drawback that it is not possible to completely prevent the arm A from swinging laterally, and it is not possible to reliably prevent the generation of abnormal noise.

This invention was made in view of the above points,
It is an object of the present invention to provide a door check device for an automobile that has a simple structure and does not generate abnormal noise.

In order to achieve this object, the automobile door check device according to the present invention has one end of the arm pivoted to either the door or the vehicle body side eccentrically with respect to the rotation center of the door hinge, and the other end of the arm pivoted to either the door or the vehicle body side. The arm is connected to the arm so as to be movable in the longitudinal direction of the vehicle while restraining its movement in the vehicle width direction, and the center portion of the arm is held between the upper and lower parts of the arm so as to be relatively movable in the vehicle width direction and the vehicle longitudinal direction when opening and closing the door. A check member formed on the gripping portion is fixedly installed to apply a required resistance force to the movement of the central portion of the arm in the width direction of the vehicle body, and this resistance force applies the required check force to the opening and closing of the door.

Hereinafter, embodiments of the present invention will be described based on the drawings.

3 to 5, reference numeral 1 denotes an arm whose one end 1a is pivotally connected to a bracket 3 fixed to the vehicle body 2 by a shaft 4, and the other end 1b of this arm 1 is stored in a door 5. The bracket 6 is connected to an elongated hole 6a of a bracket 6 fixed to the door 4 by a shaft 7 so as to be movable only in the longitudinal direction of the vehicle body while restricting movement in the width direction of the vehicle body. The central portion 1c of the arm 1 has a circular cross section and is bent from the left to the right so as to be inclined toward the outside of the vehicle, as shown in the figure. 8 is door 5 and car body 2
This is the hinge shaft of a door hinge (not shown) that connects the arm 1 with the shaft 4, which is the center of rotation of the arm 1, as shown in the diagram.

In addition, in Fig. 3, the left-right direction indicates the longitudinal direction of the vehicle body, the left side is the front of the vehicle body, the right side is the rear of the vehicle body, the vertical direction indicates the width direction of the vehicle body, and the upper side is the outside of the vehicle,
Below is the inside of the car.

A check member 9 is fixed to the door 5 with bolts or the like and is molded from synthetic resin or the like, and in the center of the check member 9 is a central portion 1c of the arm 1.
A holding portion 10 is formed to hold the door from above and below so as to be relatively movable in the longitudinal direction and the width direction of the vehicle body when the door is opened and closed. The upper and lower portions of this gripping portion 10 are provided with elastic elements that protrude in the vertical direction so as to provide a necessary resistance force to the movement of the central portion 1c of the arm 1 in the width direction of the vehicle body within the gripping portion 10 when the door is opened and closed. A deformable protrusion 10a is provided.

Note that the central portion 1c of the arm 1 does not necessarily have to be inclined as described above, and may be straight.

With the above configuration, when the door is closed, the central part 1c of the arm 1 is located at the end of the gripping part 10 on the inside of the vehicle, as shown by the solid line in FIGS. 3 and 4, and the other end 1b is long. It is located behind the hole 6a. When the door 5 is opened from this state, as shown by the two-dot chain line, the central part 1c of the arm 1 is attached to the gripping part 1.
0, and the other end 1b moves relative to the front of the elongated hole 6a. At that time, the protrusion 10 of the clamping part 10
Since the required resistance force acts on the movement of the central portion 1c of the arm 1 in the width direction of the vehicle body by the arm 1, the required check force is applied to open and close the door, and the door 5 is held at an arbitrary opening angle. can do. In addition, when closing the door 5, the central part 1c of the arm 1
is relatively moved within the holding portion 10 from outside the vehicle toward the inside of the vehicle, and a required check force is applied.

As described above, in the present invention, a check force is applied to the opening and closing of the door by applying a required resistance force to the relative movement of the central part of the arm and the check member in the width direction of the vehicle body when the door is opened and closed. Therefore, there is no need to form a bulge in the arm as in the conventional case, and the structure of the arm, and even the structure of the entire device, can be simplified. Further, since the other end of the arm is always restrained so as not to move in the width direction of the vehicle body, it has the effect of reliably preventing the occurrence of abnormal noise due to lateral vibration.
