Description

Description: TECHNICAL FIELD The present invention relates to a striker for opening / closing a lid of a fuel inlet chamber of an automobile or the like.

More particularly, the present invention relates to a remotely operated striker that engages with a latch of an opening / closing lid of a fuel inlet chamber to maintain the opening / closing lid in a closed state and releases the engagement by operating a control cable.

2. Description of the Related Art Conventionally, there has been known a striker capable of releasing a lock of an opening / closing lid of a fuel inlet chamber from a driver's seat or the like by remote control using a control cable in an automobile or the like. As such a striker, for example,
There is a structure disclosed in JP-A-53-4512. As shown in FIG. 10, a lock case (FIG. 10) has a base end attached to an end of a conduit (35) of a control cable and has a locking member (4) and a through hole (5) at a distal end. Five
1) and slidably fitted in the lock case, the inner cable (36) of the control cable is connected to one end, and the other end is provided at the tip of the lock case (51). A joint (52) to which a lock nail (53) is attached so as to protrude out of the lock case from the through hole (5); and a joint (52) mounted in the lock case and protruding the lock nail (53) from the lock case. And a spring (54) for urging in the direction.

[Problems to be Solved by the Invention] By the way, in the conventional structure as described above,
When mounting the opening / closing lid of the fuel inlet chamber in an assembling process of an automobile or the like, it is extremely troublesome to adjust the height of the opening / closing lid to be equal to the vicinity of the fuel inlet chamber of the vehicle body. In particular, in the state where the opening / closing lid is closed, the hinge side is attached by screws or the like, so that it can be corrected by moving the attachment position, but the attachment position of the striker cannot be easily moved by design. Therefore, it is very troublesome to make the heights of the opening / closing lids uniform, and there is a drawback that extremely careful design and process control are required to make the heights uniform.

An object of the present invention is to solve such a disadvantage and to provide a striker capable of easily adjusting the position of a lock pin with respect to a vehicle body.

[Means for Solving the Problems] The striker for opening and closing the lid of the fuel inlet chamber of the present invention comprises:
(A) a lock pin provided on the wall of the fuel inlet chamber so as to be movable in the axial direction so as to be able to move in and out of the chamber; and (b) a bias pin for urging the lock pin in a direction to project into the fuel inlet chamber. A spring; and (c) an operating member for pulling the lock pin backward, and (d) the lock pin is rotatably supported around a rotation center that is eccentric with respect to the wall with respect to its own axis. And (e) restricting means for restricting the rotation of the lock pin at a desired angular position while permitting the axial movement of the lock pin.

The support means of the lock pin in such a striker can be constituted by a through-hole formed at the tip of the casing provided rotatably with respect to the wall. In that case, the through hole is eccentric from the center of rotation of the casing, and the restraining means employs a means for locking the casing to a wall.

Further, the support means for the lock pin of the striker may be constituted by a through hole of a bush rotatably provided at a distal end portion of the casing fixed to the wall. In that case, the through hole is eccentric from the center of rotation of the bush, and a locking means for locking the rotation of the bush with respect to the casing is employed as the restraining means.

Such a locking means makes the bush and the tip of the casing abut against each other at abutment surfaces perpendicular to the axis, and radially contacts either the abutment surface of the bush or the abutment surface of the casing. An extended engaging groove is formed, a projection is formed on the other side, and they are engaged with each other, and an elastic member for elastically biasing the contact surface of the bush to the contact surface of the casing is provided. sell.

Further, as a rotation supporting means of the lock pin in the striker having the basic configuration, a slide member slidably and rotatably provided in a casing fixed to the wall body and having a lock pin protruding at a tip thereof. Can be adopted. In such a case, the center of the lock pin is eccentric from the rotation center of the slide member, the rotation of the slide member is restrained when the lock pin is protruding, and the rotation of the slide member is restricted when the lock pin is immersed. The forgiving engaging means is employed as the restraining means.

In this device, a click groove extending radially is formed on one of the rear end of the slide member and the inner bottom surface of the casing opposed to the rear end, and a click protrusion engaging with the click groove is formed on the other. It is preferred to provide.

[Operation] When the casing is rotated with respect to the wall of the fuel injection chamber, or when the bush or the eccentric slide member having the eccentric hole is rotated with respect to the casing fixed to the wall, the casing is rotated with respect to the rotation center. Since the axis of the lock pin is eccentric, the position of the lock pin moves relative to the wall.
Thus, when the opening / closing lid of the fuel inlet chamber is attached in the process of assembling the body of an automobile or the like, the position of the lid can be easily adjusted by adjusting the position of the lock pin.

For normal operation, when the pulling operation member such as the inner cable is pulled, the lock pin retracts, the engagement with the latch of the lid is released, and when the pulling operation member is loosened, the lock pin protrudes again by the action of the spring, and The same action as a conventional striker, which is provided when the lid is closed, can be achieved.

Next, a striker of the present invention will be described with reference to the drawings.
