Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to crescent fastening with locking means.

[0002]

2. Description of the Related Art In conventional crescent tightening, a cap portion, which is swung by a handle, is engaged with a receiving piece as locking means for restraining the cap portion in a state where the cam-shaped engaging wall is engaged with the receiving piece. There are a type that locks automatically when rotating to the locked position, and a type that locks arbitrarily by manual operation.

[0003]

In the above-mentioned conventional locking means, the one in which the lock operates automatically is convenient in terms of locking, but the lock must be released every time the window shoji is opened. It is inconvenient in that respect. The manual locking is inconvenient in terms of locking, but is convenient in that the trouble of releasing the lock every time the shoji is opened is eliminated. Thus, each has its advantages and disadvantages. Therefore, automatic and manual locking means must be separately prepared, which is inconvenient in terms of manufacturing, management, or mounting work on site.

[0004] In view of the above, the present invention, as a locking means,
The present invention provides a convenient device that can selectively use either an automatic locking function or a manual locking function.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a spring receiving portion at both ends of a spring which constantly biases a stopper for locking a rotating plate which rotates integrally with a cap portion in the direction of the rotating plate. Are formed on both the stopper and the pedestal, and a hole is formed in the stopper for holding the connecting ball and a spring for urging the connecting ball in the direction of the back plate. A hole for holding and a hole for holding at the unlock position are formed in the back plate.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
A cap portion (2) having a cam-shaped engaging wall (1) that engages with the cap portion.
And a lever-shaped handle (3) for rotating the cap portion;
These cap portions and the handle are mainly constituted by a pedestal (5) pivotally mounted on a shaft (4).

Although the cap portion (2) is formed separately from the handle (3) and assembled together so as to rotate integrally, it may be formed integrally from the beginning.

The shaft (4) is formed integrally with the handle (3), penetrates the cap (2), the top wall (6) of the pedestal (5) and the back plate (7) on the back side thereof, and It extends into the space on the back side of (5) and has a spring hook (8) and a rotating plate (9) at its tip.
Are mounted so as to rotate integrally with the shaft (4).

In FIG. 1, the handle (3) assumes a locking position where the cap (2) engages with the receiver (not shown), and is located between the spring hook (8) and the spring hook (10) of the pedestal (5). It is held at that position by a tension coil spring (11) that is stretched. In FIGS. 1-4, the handle (3) is in a locked state in which the engaging wall (1) of the cap (2) is engaged with the receiver, and when the handle (3) is rotated clockwise by 180 degrees, the cap (2) is rotated. The engagement wall (1) reaches the unlocked position where the engagement with the receiver is released, and is held at that position by the spring (11).

The rotating plate (9), together with the stopper (12), locks the handle (3) at the locking position of the cap (2), and comprises a small-diameter arc portion (13) and a large-diameter arc. It has a portion (14), and two step portions (15) are formed symmetrically at the joint portion of the arc portions, and can be used in a right and left manner.

The stopper (12) is installed in the space between the pedestal (5) and the back plate (7) so as to be able to linearly reciprocate in the longitudinal direction of the pedestal. (15) an engaging portion (16) for locking the rotary plate, a slot-shaped spring receiving portion (18) into which one end of the compression coil spring (17) is inserted,
The pedestal (5) has an extension (22) through which the knob (21) is fixedly inserted through the hole (20) of the side wall (19). The other end of the spring (17) is received by a spring receiver (23) of the pedestal (5), and the spring (17) constantly urges the stopper (12) toward the rotating plate (9). I have.

[0012] The stopper (12) in FIG. 3,
The engaging portion (16) engages with the step (15) of the rotating plate (9) to prevent rotation counterclockwise around the axis (4) and locks the rotating plate (9) in that position. ing. At this position, the cap (2) is locked. Knob (21)
Is moved to the right, the stopper (12) is disengaged from the step (15) of the rotating plate (9), and the cap (2) can be rotated 180 degrees to its unlocked position. When the cap (2) is in the unlocking position, the tip of the stopper (12) is pressed against the arc (14) of the rotating plate (9) by a spring (17). Then, when the cap (2) is rotated by 180 degrees to its locking position, the engaging portion (16) at the tip of the stopper (12) automatically engages with the step (15), and the rotating plate (9) To lock.

The stopper (12) further comprises a shaft (4)
Hole (2) extending in the direction parallel to
4), and another compression coil spring (25) and a coupling ball (26) biased by the spring are inserted into this hole (FIG. 5) .
The two holes (27), (2
8) are provided on the back plate (7) so as to be aligned in the longitudinal direction of the pedestal (5) (FIG. 5). When the stopper (12) is in the locked position, the coupling ball (26) is engaged with the hole (27) (FIG. 5) by the spring (25) to hold the stopper in that position. When the stopper (12) is moved to the left (FIG. 5) to the unlock position, the connecting ball (2) is moved.
6) is engaged in another hole (28) to hold the stopper in that position. In this case, the stopper (I2) cannot automatically lock the rotating plate (9).
