Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to an improvement of a bag lock.

[Conventional technology]

Among the conventional bag locks, there is one published in Japanese Utility Model Publication No. 17091/1983.

This structure allows the left and right locks to be unlocked by operating an operator provided approximately in the center of the case body.

[Problem that the invention attempts to solve]

In the above-mentioned conventional device, it is necessary to attach an operating member, which makes the structure complicated and the manufacturing process complicated. Therefore, the cost is high.

[Means for solving problems]

An object of the present invention is to provide a bag lock that can be unlocked simply by operating the handle by changing the conventional structure and requiring no special operating member.

Therefore, the present invention incorporates a locking member that is engaged with a hook attached to the lid inside the lock case attached to the bag body, and a protrusion exposed in the receiving part of the handle provided on the body. The lever is protruded from a slidable operating rod that connects to the locking fitting, and a push-up spring is applied to the pivot shaft and the lock operating pivot shaft, which are installed opposite to each other at both ends of the lowering hand, to support the lowering hand so that it can move up and down. At the same time, bring the end face of the lock operating pivot shaft close to the protrusion, push down the lowering hand to bring it down,
When the lock actuation pivot shaft is rotated 1/4 turn and moved laterally, the thin piece that pushes the protrusion does not hit the stopper protruding in the receiving member at the position directly above the protrusion, and the lock operation pivot It is installed at the tip of the shaft.

〔Example〕

In the figure, 1 is a lock case, 2 is a handle, and 3 is a support member for the handle, which is attached to the bag body side together with the lock case 1.

A pivot shaft 4 and a lock operating pivot shaft 5, which are provided opposite to each other at both ends of the lowering hand 2, are inserted into the receiving member 3 through notches 6 and 6' at both ends of the receiving member 3 so as to be supported by the receiving member 3. , are received by stoppers 7, 7' on the inner surface of the receiving member. Further, bending push-up springs 8, 8' are attached to the lower sides of both shafts 4, 5 to prevent the lowering hand 2 from falling down, and a bellows 9 acting in a direction in which the lock operating pivot shaft 5 moves away from the stopper 7 is attached to the shaft 5. Wrap it around.

Reference numerals 10 and 10' designate a pair of actuating rods built into the lock case 1, which are respectively engaged by pins 12 and 12' at eccentric positions of a rotary plate 11 that is pivotally connected to the lock case. Locking members 14, 14' are provided at the tips of the coil springs 13, 13'. Further, ∪-shaped springs 16, 16' are provided at the tip of the hooks 15, 15' that press against the hooks 15, 15' that protrude from the lid body, and the hooks 15, 1
5' is engaged and locked by the engagement members 14, 14'.

Therefore, the lock operating pivot shaft 5 is integrally provided with a projecting piece 18 that projects from the elongated hole 17 formed in the lock case 1 and is pushed by the lock operating pivot shaft 5. Further, the lock operating pivot shaft 5 is provided with a thin piece portion 19 that can be removed by avoiding the stopper 7 when the lowering hand 2 is tilted and rotated 1/4 turn.

[Effect]

When the lowering hand 2 is pushed up from the position shown in Figure 1 to the position shown in Figure 3, brought down as shown in Figure 4, and slid laterally (in the direction of the arrow) as shown in Figure 5, the operating rod will move. , the left and right locking metal fittings will be released from the hooks and the lock will be unlocked.

When the lower hand is standing up, pressing down will not move the 3rd position.
As shown in the figure, the tip of the shaft 5 hits the stopper and cannot be unlocked. Furthermore, unless the lower hand is pushed down, even if the lower hand is tilted down, the thin piece 19 of the shaft 5 hits the stopper and the lock cannot be unlocked.

[Effect of idea]

According to the present invention, there is no need for an operating member, and the lock can be unlocked by simply pushing the lower hand down, knocking it down, and then sliding it in the horizontal direction, so operation is simple and there is no need to attach an operating member. It can be made at a low cost since it only requires a small amount of time, and its performance and value as a bag lock are improved.

Claims (1)

[Scope of utility model registration request] A locking member that is engaged with a hook attached to the lid body is installed inside the lock case attached to the bag body, and a protrusion exposed in the receiving part of the lower hand provided on the body is used as the locking metal fitting. A push-up spring is applied to the pivot shaft and the lock operating pivot shaft, which protrude from the connected slidable operating rod and are installed opposite to each other at both ends of the lowering hand, to support the lowering hand so that it can move up and down. Bring the end face of the actuating pivot shaft close to the protrusion, push down the lowering hand to bring it down, and move the lock actuating pivot shaft 1/2.
A thin piece is provided at the tip of the lock operating pivot shaft to push the protrusion into place without hitting the stopper protruding in the support member at a position directly above the protrusion when the lock is rotated four times and moved laterally. Bag lock.
