Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a lock constructed with a handle that is attached to a bag made of a hard material such as an attachment case, and in particular to a temporary lock.

[Conventional technology]

Conventionally, this type of bag lock has been manufactured by, for example,
-There is something published in Publication No. 136557.

This bag lock is equipped with a lock case attached to the inner surface of the bag body, a decorative frame fixed to the outer surface, and a handle and its fixing member, which are formed separately.

The conventional device has a complicated structure, requires troublesome installation work, and has a large number of parts, resulting in high cost. Another disadvantage is that the pivot pin of the lower hand is exposed, which spoils the appearance.

[Problems to be Solved by the Invention] An object of the present invention is to provide a bag lock that has a simple structure, a small number of parts, and can be inexpensive, while eliminating the above-mentioned conventional drawbacks.

[Means for solving problems]

The means of the present invention is composed of an elongated lock case 2 fixed to the inner surface of the bag body 4, and a pair of handle attachment members 3 that support both ends of the handle 1. A temporary lock is provided in which an engaging pin 18 that engages with a locking hook piece 17 attached to the lid of a bag is supported by a connecting piece 16 connected to a rotor 12, and is rotatably attached to a lowering hand attachment member 3. Operation piece 10
The fulcrum angle shaft 11 of the bag body 4 is fitted into the upward square hole 13 of the rotor 12 through the insertion hole 30 of the bag body 4.

[Effect]

When the temporary lock operating piece is rotated around the square shaft from the position shown by the solid line in Figure 5 to the position shown by the chain line, the rotor rotates together with the locking pin, and the engagement pin moves as shown in Figure 4b. It can be removed from the locking hook and the lid can be opened. If the lid is closed in this state and the temporary locking operation piece is turned to its original position, the engagement pin will engage with the locking hook piece, making it impossible to open the lid.

〔Example〕

In FIGS. 1 and 2, 1 is a handle, 2 is an elongated lock case, and 3 is a handle attachment member for attaching the handle 1 to the bag body 4. The lock case 2 is fixed to the inner surface of the bag body 4, and a hole 5 made in the bag body 4
Fixing rod parts 7 and 8, which are integral with the handle attachment member 3, protrude from 6 and 6 into the lock case 2 on the inner surface of the main body 4, and screws 9 connect the lock case 2 and the handle attachment member through the bag body 4. Fix 3.

A temporary lock operation piece 10 is rotatably attached to a lower hand attachment member 3. Therefore, a square shaft 11 is provided protruding from the lower surface of the temporary lock operating piece 10, and is fitted into the square hole 13 formed in the rotor 12 in the lock case 2 through the hole 30 of the bag body, and the temporary lock is temporarily locked using the square shaft 11 as a fulcrum. When the operation piece 10 is turned, the rotor 12 is also turned together.
The lower side of the rotor 12 is formed into a corner 12', and a rotation angle regulating spring 14 is crimped onto this corner.
It is designed to stop when 2 has turned 90 degrees.

The rotor 12 is connected to a connecting piece 16 by a connecting pin 15, and the connecting piece 16 has an engaging pin 18 that engages with a locking hook piece 17 (FIG. 4) attached to the lid side of the bag.
As shown in FIGS. 3 and 4, the engaging pin 18 enters the elongated hole 20 of the guide piece 19 fixed to the lock case 2, performs a linear movement, and is engaged with the locking hook piece 17. .

Reference numeral 21 indicates a main lock, which is attached to the center of the lock case 2 and has a rotating shaft 23 protruding from the bottom end with a cam 22. When the key is inserted into the exposed upper surface of the bag body 4 and turned, the key shown in FIG. As shown in FIG. 2, the cam 22 is configured to rotate, and the left and right operating rods 24 slidable by the cam 22 are integrally provided with a locking piece 24' and are actuated by a return spring 25. The locking piece 24' is bent into an L shape as shown in FIG.
When the cam 22 is rotated from position a to b in FIG. 6 and the operating rod 24 is slid, the upright portion 24a of the locking piece 24' enters the notch 26, prevents the temporary lock operation piece 10 from rotating, and is locked. The lock is unlocked by returning the cam 22 to the position shown in FIG. 6a.

[Effect of idea]

According to the present invention, it can be assembled with a small number of parts and a simple structure. Therefore, a bag lock with good appearance can be obtained at low cost.
