Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lock device which can be used for fixing a removable roof of an automobile, a hood or various members.

[0002]

2. Description of the Related Art Conventionally, a base, a lever whose one end is rotatably supported by the base, a locking ring swingably attached to the lever, and the lever can be engaged with and disengaged from the base. 6, the leg b of the locking ring a is expanded, the leg end c is applied to the support hole e of the lever d, and then the leg is released, as shown in FIG. Is narrowed and the leg end portion c is inserted into the support hole e. However, according to this assembling method, a material that is easily deformable must be used as the locking ring, and therefore the strength of the locking ring cannot be sufficiently obtained. Further, since the locking ring is forcibly opened or closed, the locking ring may be deformed in the width direction, and the accuracy of parts cannot be improved.

DISCLOSURE OF THE INVENTION The present invention provides a locking device in which a locking ring is attached to a lever without deforming the legs of the locking ring at all.
Device provided with a lever whose one end is pivotally supported on a base, a locking ring swingably attached to the lever, and means for engaging and disengaging the lever with respect to the base A locking device, characterized in that a cutout is provided in one of the bases of the legs of the locking ring, and a leg end insertion hole provided with a lever is provided with an insertion portion corresponding to the cutout. It is in.

[0004]

1 to 5 show a locking device according to the present invention, which comprises a base 1, a lever 2 having one end pivotally supported on the base, and a swingably mounted lever. Locking ring 3
And a means 4 for allowing the lever 2 to be freely engaged with and disengaged from the base 1, and one of the legs 5 of the locking ring 3 is provided with a notch 6
And the insertion portion 9 corresponding to the cutout portion 6 is provided in the insertion hole 8 of the leg end portion 7 provided in the lever 2.

As shown in FIGS. 1 and 2, the base 1 is provided with bolt insertion holes 11 and 12, and a central opening 13 thereof.
A step portion 14 is formed on the lower end of the lever 2, and the lever 2 is supported by a shaft 15 at one lower end portion. Reference numeral 16 is a spherical projection provided adjacent to the shaft 15.

The lever 2 has a shaft hole 17 at the lower end of one end for fitting the shaft 15, and a shaft hole 18 for the engaging / disengaging means 4 at the center. Reference numeral 19 is a protective member attached to the end surface of the base 1 by screws 20.

The engagement / disengagement means 4 has an engaging member 23 having a hook 21 at the tip and an operating surface 22 at the base, a shaft 24 for pivotally supporting the member 23 on the lever 2, and a member 23. Is provided with a coil spring 25 for constantly biasing the counterclockwise.

Reference numeral 26 is a stopper member attached to the lever 2, and member 23 is the other stopper portion 27 of the lever 2.
It is possible to rotate around the shaft 24 between the stopper member 26 and the stopper member 26.

The lock device is assembled in the following manner. As shown in FIGS. 3 and 5, with respect to the lever 2, the locking ring 3 is lowered from above, and the notch 6 is made to substantially match the level of the insertion portion 9, and then the locking ring 3 is moved in the arrow direction. The notch portion 6 is moved to pass through the insertion portion 9, and the leg end portion 7 is inserted into the insertion hole 8.

In FIG. 4, after the locking ring 3 is inserted into the insertion hole 8, the locking ring 3 is rotated in the direction of the arrow, and this is the protrusion 1.
6 shows the state of being supported by hitting 6.

In the state shown in FIG. 4, the engagement / disengagement means 4 is assembled to the lever 2 by the support shaft 24 and the coil spring 25, the base 1 is placed thereon, and the lever 2 is attached to the base 1 by the shaft 15. Then, the movement of the locking ring 13 in the left-right direction is blocked by the base 1, and the locking ring 3 is completely prevented from coming off the insertion hole 8. 1 and 2 show the state.

The locking device is used for attaching and detaching the A member and the B member, as shown in FIGS. It is attached to the A member by bolts and nuts 29.

FIG. 7 shows the A member connected to the B member by the locking device of the present invention. In this state, the locking ring 3 engages with the engaging recess B'of the B member, and the means 4
The hook portion 21 of is engaged with the step portion 14 of the base 1.

Now, in FIG. 7, when the engaging member 23 is rotated in the direction of the arrow, the hook portion 21 is disengaged from the step portion 14, and the lever 2 is rotated around the shaft 15 to thereby cause the locking ring. 3 is disengaged from the engaging recess B'of the B member. This state is shown in FIG.

When connecting the B member to the A member again,
In FIG. 8, if the locking ring 3 is put into the engagement recess B ′ and then the lever 2 is pushed up in the direction of the arrow, the operation opposite to the above is performed and the connected state shown in FIG. 7 is obtained.

The lock device of the present invention is used, for example, in an automobile having removable roofs C and D shown in FIG.

FIG. 10 is a view of the central roof C and the side roofs D, D as viewed from the inside of the automobile. The locking device E of the present invention is attached to each roof at two positions, as shown in the figure.

In this case, each roof C, D, D is
The member B corresponds to the engaging portion on the side of the automobile body.

[0019]

According to the present invention, it is possible to provide a locking device having a high-strength locking ring which can be used for fixing a removable roof of an automobile, a hood or connecting various members.
