Description

[Detailed explanation of the idea] The present invention relates to an automobile gas filler lock device.

In a passenger car, the gas filler cap provided at the fuel filler port of the gas tank is usually housed inside a panel, and the gas filler cap can be seen by opening a cover that is rotatably attached to one side of the panel.

The gas filler lock device is a device that closes and holds the cover of this panel portion, and as shown in FIG. 1, it consists of a part of a key cylinder and a filler lock.

A key cylinder (KC) is attached to the cover, so-called filler lid, and a claw piece N is fixed to the tip of the cylinder KC. Rotate to.

The filler lid L is always biased in the opening direction by a leaf spring S provided on the panel portion P.

A filler lock FL is attached to a panel portion P adjacent to the filler lid L.

The filler lock FL has a rod 2 slidably provided on an arm of the base 1.

The rod 2' is urged to pop out toward the key cylinder, and its tip engages with a stopper or the like using a protrusion device that engages with a pawl on the bottom of the locked key cylinder, thereby stopping the rod 2'. .

A lever 3 is rotatably attached to the base 1, and a spring 4 is engaged to bias it counterclockwise in the figure.
One end thereof engages with a retaining groove drilled in the rod 2', and the other end is attached to the end of the cable 5.

The cable 5 is capable of transmitting push/pull motions from a remote location.

The rod 2' is engaged with the lever 3 and is slidably biased toward the protruding position under the action of a spring 4' that biases the lever 3 to rotate.

Since the gas filler lock device is configured as above,
When the key is in the locked state, the tip of the claw 6 engages with the tip of the rod 2, and the filler lid L is held in the closed state, but when the key is twisted to unlock, the claw piece 6 rotates. Since the connection with the tip of the rod 2 is released, the filler lid L
springs open with force due to the restoring force of the leaf spring S.

The rod 2' can also be slid to the right by rotating the lever 3 that engages with it in a clockwise direction using the cable 5 at one end thereof, thereby releasing the engagement with the claw piece 6 at its tip. .

That is, if one end of the cable provided at the other end of the lever 3 is connected to a cable operating handle provided in the driver's seat, the filler lid L can be opened by operating this handle while in the driver's seat.

By the way, this type of gas filler lock device uses a plate spring to raise the filler lid, but the spring is attached as a separate part when the filler lock is assembled to the vehicle body, so it is not easy to work with. On the other hand, it has the disadvantage of increasing the number of parts.

The present invention is intended to eliminate the above-mentioned drawbacks, and will now be described with reference to embodiments shown in the drawings.

The upper end of the lever 3 penetrates and engages the slot 8, and the compression coil spring 4 is wound around the right end of the rod 2.

The base 1 is fixed to the panel part P adjacent to the filler lid L by screwing a nut into a flange collar or the like for supporting the cable 5 provided with the screw 12' as shown in FIGS. 1 and 6. .

In the present invention, a compression coil spring 4 having an extension force and a torsion force is wound around the rod 2 of the filler lock FL, so that the rod 2 is slidably biased to the pop-out position, and rotationally biased to the pop-out position. An arm piece 6 protruding in an L-shape from the tip of the rod 2 that is restrained by the rod 2 is brought into contact with the filler lid L, and the filler knot L is made by utilizing the rotational biasing force of the compression coil spring 4 acting on the rod 2. This is an attempt to flip up and open the door.

The compression coil spring 4 is wound by locking one of its ends to a washer 9 provided on the rod 2, and locking the other end to an arm portion 10 formed on the base 1 to support one end of the rod 2.
After locking it and twisting it at a predetermined angle to obtain a constant rotational stress,
Extend one end of the strand and hang it against an appropriate fixed part such as the lever 3 or the wall of the base 1, and extend the other end of the strand and insert it into the split groove 7 drilled in the end face of the rod 2. Bye.

Note that the washer 9 may be of any type as long as it can lock one end of the compression coil spring 4, and may be provided integrally with the rod 2 in the form of a flange.

Here, it is preferable that the groove 7 has a width and length such that engagement of the end of the spring 4 does not interfere with sliding of the rod 2.

Further, the groove 8 formed in the rod 2 into which the end of the lever 3 can be inserted and engaged is such that the cross section thereof is as shown in FIG. It is preferable to have a narrow width at the center that matches the thickness of the lever 3, like two fan-shaped faces facing each other, and gradually widen in a fan-like shape toward both the upper and lower opening ends.

The lever 3 is urged to rotate counterclockwise under the action of the compression coil spring 4 in order to engage the rod 2, and its lower end engages with the vertical wall 11 of the base 1 as shown in FIG. It is stopped and stopped.

Therefore, the rod 2 is stopped at a predetermined protruding position.

In this way, when the vertical wall 11 formed on the periphery of the base 1 is used as a stopper and the lower end of the lever 3 is engaged with it to stop the counterclockwise rotation of the lever 3, it is necessary to The position of the vertical wall 11 of the base 1 may be appropriately selected.
