Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a lock for a bag, particularly a bag with a hard handle such as an attaché case or a trunk.

[Conventional technology]

Conventionally, there is a bag lock published in Japanese Utility Model Application Publication No. 136557/1983.

This item has a structure in which a handle is attached to the center of the bag body, locks are fixed to both left and right sides of the handle, and when the lid is closed, the lock piece fixed to the lid is locked to the lock. ing.

[Problem that the invention attempts to solve]

In the conventional bag lock, when opening the lid, it is necessary to slide the operator of the lock from side to side. Therefore, a structure for sliding must be provided, and the operation is troublesome.

[Means for solving problems]

An object of the present invention is to provide a bag lock that can be locked by simply raising the handle with the lid closed, without sliding the operator like in the conventional bag lock. Therefore, the present invention forms an inverted ∪-shaped notch at both ends of the handle that is pivotally attached to the bag body so that it can be turned upside down, and the notch has a locking protrusion that engages when the handle is in the upright position when the lid is closed. A locking body with a keyhole fixed to the lid body is provided with either one of an engaging projecting strip and an engaging recessed strip that protrudes from the joint edge of the bag body and the lid body and engage with each other, and the above-mentioned A cam that is rotated by a key is rotatably mounted inside the lock body having a locking protrusion, and a lock lever that is slid by the cam is formed into a locking protrusion from the lock body by applying a return spring. A locking hole is recessed in the front face of the above-mentioned inverted ∪-shaped notch, into which a locking lever is inserted.

[Effect]

When the lid is closed with the handle of the bag body folded down as shown in Figure 4, the locking protrusion of the locking body enters into the inverted ∪-shaped notch of the handle, as shown by the chain line in the same figure. If you raise the lower hand as shown in the third example, it will be locked, and the lid cannot be opened unless the lower hand is pushed down. It can also be opened easily by folding down the handle.
In the present invention, when the cam inside the lock body is rotated by the key and the lock rod is inserted into the locking hole, the lid body cannot be opened even if the lower hand is pushed down.

〔Example〕

In the illustrated embodiment, 1 is a bag body, and 2 is a lid. There are recesses 5a, 5 in the center of the upper surface of the bag body 1 into which short shafts 4, 4' provided oppositely at both ends of the handle 3 fit.
Pivot pieces 5, 5' having a' are fixed, and inverted ∪-shaped notches 6, 6' formed at both outer ends of the lowering handle 3 are fitted into the upper surface of the lid 2 when the lid is closed. A locking body 8, 8' provided with circular locking protrusions 7, 7' is attached, and an engaging protrusion strip is fitted to the lid body joint edge 1a of the bag body 1 and the body joint edge 2a of the lid body 2. An engaging recessed strip 10 is fitted into which the holder 9 engages.

The locking bodies 8, 8' have a keyhole 11 on the surface,
Cam 1 rotated by inserting the key into this
2 is installed inside the locking body 8, 8', and the locking body 8,
A horizontal through hole 13 passing through the locking protrusions 7, 7' is bored in 8', a locking rod 14 that slides by the rotation of the cam 12 is inserted, and a spring 15 is applied in the return direction. Locking hole 1 into which the locking rod 14 enters and locks
6 is formed deep inside the inverted ∪-shaped notches 6 and 6'.

In addition, 17 in the figure is a raised part formed on the locking projections 7, 7', which collides with the stepped part 18 formed in the inverted U-shaped notches 6, 6' of the lowering hand 3, and protrudes in the middle of the stepped part 18. The lowering hand 3 is made to stand up beyond the raised part 19, so that the lowering hand 3 is stabilized in an inverted state. 20 is an elastic regulating piece integrated with the cam 12 that fits into the groove 21 on the inner surface of the locking body, and the cam 12 is in the locked position.
stabilize.

[Effect of idea]

According to the present invention, the lid can be opened and closed by turning the lower hand upside down.
The locking operation is extremely simple and easy, and it can also be completely locked with a key.

[Brief explanation of drawings]

The drawings show an embodiment of the bag lock according to the present invention. Figure 1 is a plan view of the bag lock with the handle upright, and Figure 2 is a plan view of the bag lock with the handle tilted down and the lid slightly open. A plan view, FIG. 3 is an enlarged sectional view taken along the line A-A in FIG. 1, FIG. 4 is an enlarged sectional view taken along the line B-B in FIG. 2, and FIG.
