Description

DETAILED DESCRIPTION OF THE INVENTION (1) Purpose of the Invention (Field of Industrial Application) The present invention relates to a handle cap of a gasoline tank of an automobile.

(Prior art and problems to be solved) The cap that opens and closes the gasoline inlet in a gasoline tank of an automobile is normally rotated and opened and closed by a screw, but the screw loosens due to vibration and the like and leakage of gasoline and gas may occur. In order to prevent it from occurring, when using the latch and the claw that engages with this to rotate and tighten the cap,
A structure in which the latch and the claw are tightened until they are idle has already been proposed, for example, as disclosed in Japanese Patent Laid-Open No. 54-120089.

With this configuration, the screw of the cap body can be securely tightened to the feeler neck to a certain tightening position, and the risk of leaving the tightened state too loose can be avoided.

At the same time, in this type of device, since the idling mechanism as described above is generally arranged on the flange portion formed on the cap body, the outer diameter of the handle portion becomes large, and this portion collides with other objects. The handle is disengaged from the cap body, and since the idling mechanism is formed separately from the handle portion and the meshing portion of the cap, the structure becomes complicated.
The handle operation moves up and down regardless of the tightening of the feeler neck and the cap body, so there is a problem that operability is poor.

The present invention has been made to cope with such a situation, and a mechanism portion that is disposed between the handle and the cap body and that regulates the tightened state of the cap is arranged in the axial direction of the cap body as much as possible. It is an object of the present invention to provide a handle cap of a gasoline tank which can be extended so as to avoid the above problems.

(2) Structure of the Invention (Technical Means for Solving the Problem and Its Action) In order to achieve the above object, the present invention is a cap provided with a screw threaded to a feeler neck of a gasoline tank for automobiles and a flange for receiving a seal ring. A main body, a handle fixed so as to cover the cap main body, and a ring disposed between the cap main body and the handle and fixed to the handle. An annular support portion extending in the axial direction of the cap body and having a plurality of claws on the outer periphery is formed, and the ring is arranged so as to concentrically surround the annular support portion, and a plurality of rings are provided inside the ring. The elastic arm of the claw is engaged with and disengaged from the claw, and the claw and the engaging end of the arm are rotated in a direction of releasing the cap body from the feeler neck. The handle cap of a gasoline tank, wherein the handle caps are extended in the same direction so that the pawls and the engaging end portions are disengaged with a predetermined torque when engaged and rotated in the tightening direction. Is.

With such a configuration, it is possible to reduce the size of the handle cap as a whole and to obtain a handle cap in which the tightening torque does not substantially change.

(Description of Embodiments) FIG. 1 is a side view showing a handle cap according to an embodiment of the present invention with a part cut away.
Is a screw 1 for screwing into a feeler neck (not shown)
0, a cap body 11 having a flange 3 for receiving the seal ring 4, and a handle 1 capped on the cap body 11.

A small chamber 11 'is formed in the lower portion of the cap body 11, and a known valve device is installed therein.

An annular support portion 12 is formed on the cap body 11 on the axially outer side on the side where the handle 1 is mounted, and a plurality of claws 7 are provided on the outer side in the radial direction of the annular support portion 12. It is assumed that the annular support portion 12 and the claw 7 are all arranged inside the outer peripheral surface of the cap body 11.

A handle 1 is attached to the upper portion of the cap body in the figure. The handle is formed in a generally dish shape as a whole, and a rib 14 protruding upward and a suitable number of claws 13 are formed along the edge of the release side. It shall be press-fitted and fixed (upward in the drawing).

A ring 2 is disposed between the lower surface 15 of the handle 1 and the upper surface of the cap body 11, and a protrusion 16 formed on the ring 2 engages with a hole formed in a rib of the handle 1. The handle 1 and the ring 2 are fixed.

A plurality of cantilevered arms 18 are formed inside the ring-shaped ring body 17 of the ring 2, and the free ends of the arms 18 are engaged ends 19 that are further curved inward.
Are provided, and the engaging end portions 19 are disengaged from the claws 7 of the annular support portion 12.

The angle (θ) of the engagement end portion 19 with respect to the diameter passing through the tip thereof is set to 15 ° to 45 °, preferably about 30 °. Also, the extending direction of the claw 7 provided on the annular support portion 12 is, like the engaging end portion 19, an angle (θ) with respect to the diametrical direction, as shown in FIG. Is set at about 30 °.

With this configuration, when the cap is rotated in the removing direction, the engaging end portion 19 surely engages with the claw 7, and a large removal torque can be transmitted to the cap body.

On the inner peripheral surface of the nong body 17, a recess 20 is formed at a position corresponding to the arm so that the arm 18 can freely rotate and displace when torque is regulated. And the arm 18 is easily demolded.

As described above, the cap 7 is rotated in the direction to remove the cap from the feeler neck by setting the extending directions of the claw 7 of the annular support 12 and the engaging end 19 of the arm 18 of the ring 2 to be substantially the same. Occasionally, the engagement is ensured, and when rotating in the tightening direction, the engagement is disengaged with a predetermined torque. Further, when the handle 1 is rotated in the tightening direction, the arm 18 is provided inside the ring 2, so that the handle 1
Since the gripping force does not affect the contact pressure between the claw 7 and the engaging end portion 19, the tightening torque can be maintained substantially constant.

(3) Effects of the Invention As described above, according to the present invention, in the handle cap that opens and closes the feeler of the gasoline tank, by means arranged in the axial direction of the cap body at the connecting portion between the handle and the cap body. Since it is configured to rotate and open / close, the outer diameter of the handle cap can be configured to be as small as possible, and the same as the arrangement angle of the engaging / disengaging members, the pawls for restricting torque. Since it is set to, the force applied to the handle can be reliably transmitted to the cap body.
