Description

[Detailed Description of the Invention] The present invention relates to an improvement of a stopper rubber for a door checker for an automobile.

Automotive door checkers are designed to moderate the opening angle of the door by holding a checker lever pivotally attached to the vehicle body with a door checker attached to the door.When the door is fully opened, the stopper rubber of the checker lever is held against the door checker. The fully open position is regulated by

However, with conventional stopper rubbers, the rubber was simply fixed to the checker lever, so if the rubber is hard, the load when fully opened will act shockingly on the vehicle body side and the stopper plate, causing damage to the hinge pin, etc. On the other hand, if the rubber was soft, the door could open beyond the full-open limit and collide with the front fender or front door.

This idea was made in view of the above-mentioned conventional problems, and the stopper rubber is constructed by pasting together sheet-like soft rubber and hard rubber in the direction of insertion and removal of the checker lever, and the relationship between load and strain is improved. By setting non-linear characteristics, it is devised to compensate for the shortcomings of only softness and only hardness, thereby preventing impact action and opening beyond the regulated position.

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

As shown in FIGS. 1 and 2, the door checker has the tips of a pair of checker levers 4, 4 pivotally connected to a bracket 2 fixed to a pillar of a vehicle body 1 with a pin 3, and A stopper plate 5 and a stopper rubber 6 are fitted to the end and prevented from coming off with a stopper pin 7.

On the other hand, the inner panel of the door 8 has a slider 9,
9 and spring rubbers 10, 10 are closed with a case cover 12, and the screw 1 is closed.
3 and 13, and the case 11 and cover 1 are
The checker levers 4, 4 passing through the openings 11a, 12a of 2 are held by the sliders 9, 9,
The door 8 is opened and closed by inserting and removing the checker levers 4, 4 between the sliders 9, 9 when the door 8 is opened and closed.
It is designed to give moderation to the opening angle.

The stopper rubber 6 is constructed by pasting together a sheet-like soft rubber 6a and a hard rubber 6b in the direction of insertion and removal of the checker levers 4, 4,
As shown in FIG. 3, the relationship between load and strain was a linear characteristic a, but in the case of the rubber of the present invention, it becomes a nonlinear characteristic b.

Therefore, just before the door 8 is fully opened, the soft rubber 6
Since a is pressed against the case 11 and flexed to become a cushion, and then the hard rubber 6b is flexed to become a cushion, the impact action is alleviated and the door 8 is prevented from opening beyond the regulated position.

As mentioned above, in this invention, the stopper rubber is constructed by pasting together sheet-like soft rubber and hard rubber in the direction of insertion and removal of the checker lever, so the load when fully opened acts on the soft rubber first. Then, since it acts on the hard rubber, the impact is alleviated, and since the door is fully opened, it is securely regulated, so there is no possibility of the door colliding with the front fender, etc.

In addition, since the sheet-like soft rubber and hard rubber are simply pasted together in the direction in which the checker lever is inserted and removed, the structure is extremely simple. Although it is expensive, the proposed method only involves gluing ready-made rubber sheets together and cutting them into rectangular frames, which reduces manufacturing costs.
