Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to an improvement of a bag lock.

[Conventional technology]

An example of a conventional bag lock of this kind is the Utility Model 58-
I will list what was published in Publication No. 136557. All of these conventional bag locks have a lock body attached to the bag body and a latch plate attached to the lid body, so that the latch plate is latched to the lock body when the lid body is closed.

Therefore, it takes time and effort to attach the locking plate to the lid body. In addition, since the sash edge of the lid body is thin, it must be fixed to the side plate of the lid body with pins, screws, etc. As a result, the heads of pins and screws are exposed to the outside, spoiling the appearance. Furthermore, if the fixed position of the locking plate shifts even slightly,
This causes the inconvenience of not engaging the lock body. In particular, conventional bag locks absolutely require a locking plate.

[Problem that the invention attempts to solve]

The object of the present invention is to provide an innovative product as a bag lock that eliminates the need for a locking plate, which has traditionally been an indispensable member.

[Means for solving problems]

The means of the present invention is to form a guide window hole approximately in the center of a pair of left and right lower hand support members fixed to the bag body, and to accommodate a push operation member on which a return spring is applied so as to be movable back and forth. A lock case fixed to the inside of the bag is swingably equipped with a locking plate with a spring acting forward, and the upper end of the locking plate is integrated with the sash edge of the lid hinged to the bag body. an inclined surface that is pushed by the projecting edge and a locking pawl that engages with the projecting edge, and the pressing operation member has an actuating piece protruding inwardly that pushes the locking plate and releases the locking pawl from the projecting edge. That's true.

[Effect]

When the open lid body is closed, the slanted edge of the upper end of the locking plate is pushed by the protruding edge integrated with the sash edge, and the locking plate is once moved rearward against the spring and is locked with the locking pawl.

To open the lid 2, press the push-operation member with your fingertip, and the latching plate moves backwards against the spring as it is pushed by the actuating piece, and the latching pawl separates from the ridge, allowing the lid to be opened. .

〔Example〕

The structure of the present invention will be explained with reference to the illustrated embodiment.
In the figure, numeral 1 is the bag body, and 2 is the lid. A bag body 1 surrounds a sash frame 3, a sash edge 4 is fixed to a lid body 2, and a projecting edge 4' is integrally provided on the inner side of the sash edge 4. Reference numeral 5 denotes a pair of left and right support members that support the lowering hands 6, and when they are fixed to the sash frame 3 from the back side with set screws 7, a locking plate 8 that locks on the ridge 4' is integrally formed so as to be able to swing. A synthetic resin lock case 9 (see FIG. 4) is attached to the inner surface of the sash frame 3. A V-shaped spring 10 is provided on the back side of the locking plate 8 to press the locking plate 8 forward, and a bent portion 10' provided at the upper end of the spring 10 is inserted into a through hole 11 provided in the lock case 9. The locking plate 8 is provided with a sloped surface 8a at the upper front end thereof, and a locking claw 8b is provided below the sloped surface 8a. The support member 5 of the lowering hand 6 has a guide window hole 12 formed in its approximate center, and a push operation member 13 is accommodated in the guide window hole 12 so as to be slidable back and forth, and integrally protrudes from the back side thereof. The operating piece 14 passes through a through hole 15 made in the sash frame 3 so that its tip comes into contact with the latching plate 8, and a return spring 16 is compressed between the back surface of the pressing operation member 13 and the sash frame 3. be. When the pressing operation member 13 is pressed against the spring 16, the actuating piece 14 pushes the locking plate 8 backward against the spring 10, and the locking claw 8b of the locking plate 8 is removed from the flange 4'. The structure is such that 2 is open.

[Effect of idea]

In the present invention, the protruding edge provided on the sash edge of the lid engages with the retaining plate, so there is no need for the retaining plate that was conventionally attached to the lid.
The structure is simplified, there is no fear that the locking screw of the locking plate will become loose and the locking action will be unsmooth, or that the head of the locking screw will be exposed and spoil the appearance, and the work of installing the locking plate can be omitted.

[Brief explanation of the drawing]

The drawings show an embodiment of the bag lock according to the present invention, in which Fig. 1 is a front view, Fig. 2 is a partially enlarged cross-sectional view, Fig. 3 is a partially enlarged longitudinal sectional view, and Fig. 4 is a partially enlarged longitudinal sectional view. The figure is a perspective view of the lock case.
