Description

[Detailed Description of the Invention] This invention relates to a lock that doubles as a slider of a fastener in which an opening of a bag or the like is opened and closed by a pair of slide fasteners, one of which also functions as a lock.

Conventional fastener slider locks have a large number of parts for a narrow lock housing, have a complex structure, take time to manufacture, have an expensive finish, and are prone to failure. There was a problem.

For example, in Japanese Utility Model Application Publication No. 58-85060, the base ends of a pair of key-shaped sliding plates are both pivoted to the lid body,
A chuck lock is described in which opposing protrusions are provided on the inner surface of each sliding plate, and the opposite protrusions penetrate and hold the hole in the head of the opponent runner from both sides, similar to a pinch to lock a rubber tube. . While this device is faithfully adapted to the action of grasping with the fingertips, it has a large number of parts, and moreover, an excessive load is placed on the screws that attach the shaft of the sliding plate. In addition, while the head of the opponent's runner can be easily inserted through the gap between the protrusions when temporarily locking, it is also easy to remove, and the operation is cumbersome as two sliding plates must be operated evenly. There is a problem.

The purpose of this invention is to provide a lock that can also be used as a fastener slider, which improves the problems of the conventional technology.

In other words, this invention has a locking engagement part 1 on the proximal end side.
and an engaging claw 2 protruding in the width direction on the other end side, and the width is narrower from the proximal end to the distal end, and acts on the center of the outer side of the side toward which the tip of the engaging claw 2 faces. A single actuating plate 3 provided with a portion 11 is housed so that the distal end swings in the width direction with the proximal end as a fulcrum, and a notch is formed in the side wall to expose the acting portion 11. The formed lock housing 7, the spring 4 that biases the actuating plate 3 in the direction in which the operating portion 11 is exposed from the cut hole, and the inner edge of the locking engagement portion 1 and the lock housing 7 depending on the rotational position. A locking member 5 rotatably provided so as to be engaged with each other, and a locking member 5 that closes the opening of the lock housing 7 and has a connecting portion 8 with a run member on the distal end side, and has another run member on the engaging claw 2 This relates to a lock that doubles as a fastener slider, and includes a lock case lid 10 having an insertion hole 9 into which the head A of the lock is inserted.

Examples will be described according to the drawings.

FIG. 1 is a perspective view showing the present invention in use, FIG. 2 is an enlarged sectional view taken along line A--A, and FIG. 3 is an enlarged sectional view showing the device in a locked state.

The lower side of the actuating plate 3 is formed into a slope, and a recess is provided at an appropriate portion of the slope to accommodate the upper part of the spring 4. In the lock housing 7, the operating portion 11 of the operating plate 3 is exposed through the notch hole in the lock housing 7 due to the pressure of the spring 4, and a gap is formed between the operating plate 3 and the lower side of the lock housing 7, and this gap is used for operation. This is the operating area of the plate 3.

The actuating plate 3 is formed in such a shape that both ends can slide into contact with the inner wall of the lock housing 7, but the actuating plate 3 must be closed during operation so that the actuating plate 3 can operate against the pressure of the spring 4. is in contact with either side of the lock housing 7, and its operation is restricted.

That is, when the actuating plate 3 presses the action part 11 against the spring 4, the upper right corner of the actuating plate 3 as shown in the figure becomes the lock housing 7.
This part serves as a fulcrum for operation, and both ends slide into lock housing 7 and descend. Further, when the above-mentioned pressure on the operating portion 11 is released, the operating plate 3 rises in the same manner.

As is obvious, temporary locking and unlocking are performed by a single actuating plate, but both of the above two actions involve the same method of pressing the actuating portion 11, and since only one actuating plate operates, there is no friction. The resistance is small,
Temporary locking and unlocking can be performed easily and easily.
Furthermore, since the number of parts is extremely small, failures are rare. In addition, when locking the temporary lock, as shown in FIG. As shown in the figure, the locking member 5 is rotated to stand up and engaged with the locking engagement portion 1, and the gap is eliminated to disable the operation of the actuating plate.

As is obvious, in the temporarily locked or locked state, the operating plate is not held in an activated state, but is held in its original state after it has been activated, so it places stress on other parts of the lock for a long time. Therefore, the above two conditions are extremely stable, and even if there is an impact on the fastener, the lock will not come off.
Moreover, failure can be avoided.

In addition, the drawing symbol A is the runter head of the mating slide fastener which is inserted into the insertion hole 9 of the lock that also serves as a slider of the present invention and is hooked on the engaging pawl 2, and the slider is connected to the runder. However, in the drawing, it is hidden from view because it is located on the underside of the invented lock.

As mentioned above, this invention reduces the number of parts to the maximum compared to conventional methods, which reduces manufacturing costs and reduces the occurrence of failures.Furthermore, each actuating plate is simple and light, and can be easily locked in a temporarily locked state. In addition, the lock state is maintained extremely reliably, thereby solving the problems of the prior art.
