[Structure] A flange-shaped guide 2 is provided on the outer peripheral surface of the tip of an inlet 1 of a fuel tank, and a pair of buttons 4 and 4 are provided at opposite positions of the outer peripheral surface of a cap body 3 which is detachably attached to the upper surface of the guide 2. It can be attached and removed freely. Buttons 4, 4
Engaging claws 5, 5 are provided on the lower surface of the guide 2 in association with the retracting operation. By providing springs 9 and 9 for biasing the buttons 4 and 4 to project so as to project and hold the engagement claws 5 and 5 on the lower surface of the guide 2, the buttons 4 and 4 are pushed against the springs 9 and 9. When operated, the tips of the engaging claws 5 and 5 are moved away from the lower surface of the guide.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cap of a fuel tank mounted on an automobile or the like, and more particularly to a cap having excellent workability of attachment / detachment.

[0002]

[Prior Art]

 As a conventional fuel tank cap, a cam surface is formed on the lower surface of a flange-shaped guide provided on the inner peripheral surface of the tip of the fuel tank, and a notch facing the blade piece attached to the inside of the cap is provided. It was provided in the guide. Then, after covering the inlet with the cap and inserting the spring piece into the back surface of the guide from the notch, by rotating the cap to move the spring piece along the cam surface on the lower surface of the guide, There is a cap in which the cap is brought into close contact with the upper surface of the guide by an elastically engaging action of a strip.

In such a conventional cap, there is a problem that the workability of attaching and detaching the cap is poor because it is necessary to perform the position adjustment and the fitting and rotation of the cap.

[0004]

[Problems to be solved by the device]

 The present invention has been made in view of such circumstances, and by providing a cap for a fuel tank in which the cap can be attached or removed by a so-called one-touch operation, the operability of attaching and detaching the cap is improved. The challenge is to improve

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides a flange-shaped guide on the outer peripheral surface of the tip of a fuel tank, and a pair of caps is detachably mounted on the upper surface of the guide at opposite positions on the outer peripheral surface of the cap body. The button is attached so that it can appear and disappear freely. In addition, an engaging claw is provided on the lower surface of the guide when the button is retracted and retracted, and a spring that biases the button to project and retain the engaging claw on the lower surface of the guide is provided. The feature is that it is provided.

[0006]

[Action]

 In the fuel tank cap configured as described above, when the pair of buttons provided on the outer peripheral surface of the cap body are pushed in against the spring, the engaging claws protruding from the lower surface of the guide are located outside the guide. Leave. Therefore, when removing the cap attached to the inlet, push the button on the outer peripheral surface of the cap body with your finger to move the engaging claw to the outside of the guide, and then remove the cap. Just remove it.

Further, when the cap is attached, the cap is put on the upper surface of the guide with the engaging claw retracted from the engagement area with the guide by pushing the button, and the button is released in this state. Then, the button is actuated by the urging force of the spring, and in synchronization with this, the engaging claw protrudes to the lower surface of the guide to perform the engaging action, so that the cap is attached to the inlet. Since such an engaged state is held by the spring until the button is pushed, the cap will not accidentally fall off due to steering vibration or the like. Further, when the cap is attached in an exposed state, a locking device such as a key cylinder can be provided if necessary.

【Example】

 An embodiment of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a schematic plan view showing a fuel tank cap according to an embodiment of the present invention with a button released, FIG. 2 is a front view of FIG. 1, and FIG. It is a figure. In these figures, a flange-shaped guide 2 is provided on the outer peripheral surface of the tip of an inlet 1 provided in a fuel tank (not shown).

A pair of buttons 4 and 4 are attached in a retractable manner at opposite positions on the outer peripheral surface of the cap body 3 attached to the inlet 1. Further, by disposing the engaging claws 5 and 5 at opposite positions sandwiching the guide 2, and by pivotally attaching the intermediate portion of the engaging claws 5 and 5 to the cap body 3 via the pins 6 and 6, When the engaging claws 5 and 5 are rotated around the pins 6 and 6, the tips of the engaging claws 5 and 5 are projected and retracted on the lower surface of the guide 2.

Rods 7 and 7 are fixed to the inner ends of the buttons 4 and 4, and the base ends of the engaging claws 5 and 5 are pivotally attached to the tips of the rods 7 and 7 via pins 8 and 8. There is. Then, by providing springs 9 and 9 for biasing the buttons 4 and 4 to project through the rods 7 and 7, the engaging claws 5 and 9 as shown in FIG. The tip of the guide 5 is configured to be held by protruding from the lower surface of the guide 2. Reference numeral 10 is a key cylinder provided on the cap body 3, and 11 is a lock plate that is operated to project from and retract to the lower surface of the guide 2 by the key cylinder 10.

In the fuel tank cap having the above-described structure, when the cap body 3 on the upper surface of the guide 2 is overlapped to release the buttons 4 and 4, as shown in FIGS. 1 and 2. The buttons 4 and 4 are projected and held by the biasing force of the springs 9 and 9, and are also pivotally attached to the rods 7 and 7 of the buttons 4 and 4 via pins 8 and 8. Rotates about the pins 6 and 6 so that the tip thereof is inserted into and held by the lower surface of the guide 2. That is, since the tips of the engaging claws 5 and 5 mounted on the cap body 3 which are usually superposed on the upper surface of the guide 2 are thrust and held on the lower surface of the guide 2 by the biasing force of the springs 9 and 9. The cap body 3 is prevented from falling off. By operating the key cylinder 10 as necessary, the lock plate 11 is inserted into and held by the lower surface of the guide 2 as shown in FIG. 1, so that removal of the cap due to mischief or the like can be prevented.

When removing the cap, after releasing the lock by the key cylinder 10, the buttons 4 and 4 are pushed in against the springs 9 and 9. Then, since the rods 7 and 7 fixed to the buttons 4 and 4 move toward the center of the inlet 1, respectively, the engaging claws 5 and 5 have their base ends with the pins 6 and 6 as the centers. It is rotated so as to move toward the center of 1 and its tip is made to escape from the lower surface of the guide 2.

Therefore, when the buttons 4 and 4 are pushed in, the tips of the engaging claws 5 and 5 escape from the lower surface of the guide 2 and lose the engaging function, as shown in FIG. Can be easily removed from the inlet 1.

In the embodiment, the lock plate 11 operated by the key cylinder 10 is provided to prevent the cap from being removed due to mischief, but the key cylinder 10 or the lock plate 11 or the like is necessarily provided. There is no sex.

[0015]

[Effect of the device]

 As is clear from the above description, according to the present invention, the engaging action of the engaging claws is released by pushing in a pair of buttons provided at opposite positions of the cap body. In addition, it is not necessary to perform the position adjustment and the fitting rotation of the cap as in the conventional case, and the cap can be surely attached / detached by the one-touch operation only by pushing the button.
