Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a lock fitting used to close the lid plate of a bag or the like or to attach a handle used when carrying a bag or the like. It is something.

[Prior art and its problems]

When a bag or other bag has a structure in which a closing lid plate is formed at the opening of the bag, a locking fitting is attached so as to pass between the lid plate and the bag body to accurately maintain the closed state of the lid plate. Generally, it is configured so that it can be done.

In most cases, the structure of these lock fittings is assembled as follows. That is, (1) it is composed of a combination of a lock body attached to the bag body side and a locking plate attached to the lid plate side.

(2) The locking plate has a locking tool consisting of a locking protrusion or a locking ring formed in a U-shape on the front side protruding from the back side of the locking plate. The locking tool is configured so that it can be removably fitted into a fitting hole formed in the lock body.

(3) A lock body is elastically projected from the lower surface of the fitting hole so that only the distal end locking portion thereof can freely come out and go in and out.

When the locking tool protruding from the locking plate is fitted into the fitting hole, the locking protrusion moves downward while pushing away the locking part of the lock body, and at the position where the locking protrusion has finished descending, The structure is such that the locking part of the lock body moves forward again in the direction of the locking protrusion and comes into contact with the neck of the locking protrusion to prevent it from lifting up and coming off.

That's what it was.

However, as mentioned above, conventionally used lock fittings are structured so that the locking mechanism (particularly the locking body) can freely move in and out of the body of the fitting in the vertical direction or in the front-rear direction. When the locking tool is fitted into the locking hole formed in the metal fitting body, the locking mechanism slides in the backward direction by the shaft of the locking tool, and then by the force of the spring. The structure was such that it instantly returned to its original position and locked the neck of the locking tool.

For this reason, it is necessary to provide a structure inside the lock body for sliding or retracting the lock mechanism, which has been pointed out as a disadvantage in that the internal mechanism becomes complicated and the manufacturing cost increases.

[Purpose of invention]

The present invention is intended to cope with the above-mentioned circumstances.

That is, in the present invention, the fitting hole of the locking protrusion formed on the lock body is formed into a so-called "keyhole lock," and the locking protrusion formed protrudingly formed on the lower surface of the closing plate is one of the fitting holes of the keyhole lock. It is configured so that it can be locked by inserting it into the hole with a larger diameter and then sliding it to the side with a smaller diameter. A lock body that can close this fitting hole from the bottom surface is attached to the bottom surface of the part so that it can swing and move up and down freely, and by raising this lock body, it moves to the side with a smaller hole diameter. It is an object of the present invention to provide a lock fitting configured so that a locked locking protrusion will not move or come off unduly.

[Key points of the idea]

The present invention consists of a combination of a lock body and a closing plate that abuts on the upper surface of the metal body, wherein the closing plate has a locking protrusion protruding from the lower surface of its tip, and the lock body has the following features: The upper surface has a keyhole-shaped fitting hole into which the locking protrusion protruding from the bottom surface of the closing plate can be fitted, and a fitting hole into which the locking plate can be fitted in a swingable manner. In the lock plate described above, the center portion in the length direction is pivotally supported on the lock body, and the tip thereof is pivotally supported on the lower surface of the large diameter portion of the keyhole-shaped fitting hole. The key point of the idea was to create a structure that would allow easy access.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

The lock fitting of the present invention is constituted by a combination of a lock body 1 and a closing plate 2.

The closing plate 2 is formed by integrally protruding a locking protrusion 22 on the lower surface (on the back surface) of the tip of a plate-like body 21 having an appropriate size.

Note that the closing plate 2 may have a plate-like body 21 depending on its use.
The structure of the part can be changed freely, for example, the closure body 2 is attached to the closure lid b of B, such as a bag.
When attaching the bag, form a U-shaped cross section near the base end, insert the tip of the bag's closing lid b into the gap in this U-shaped part, and use it to hold it. When attaching the handle A to the side surface of B, the closing plate 2 is formed into a flat plate, and a mechanism (not shown) for attaching the handle A is formed on the lower surface of this plate. can do. (See Figure 6) The lock body 1 is formed into an inverted dish shape with an open bottom surface, and a keyhole-shaped fitting hole 11 is bored on one side of the top surface, and an A fitting hole 13 for attaching the lock body 12 is bored on one side.

Reference numeral 14 denotes a pivot formed in the fitting hole 13 of the lock body 12, and is fitted into a fitting groove 15 formed in the central lower surface portion of the lock body 12.

The lock body 12 is formed into an elongated plate shape with a width that allows it to be fitted into the fitting hole 13, and the tip portion is formed long enough to reach the lower surface of the keyhole-shaped fitting hole 11.

Reference numeral 16 denotes a groove formed on the upper surface of the lock body 12, into which a top plate portion formed at the boundary between the lock body fitting hole 13 and the keyhole-shaped fitting hole 11 can be fitted.

Reference numeral 3 denotes a spring whose base end is fixed to the lower surface of the lock body 12 and whose distal end is a free end so as to elastically support the pivot shaft 14 fitted into the fitting groove 15 from the lower surface thereof. I have to.

[Operation of the idea]

The present invention configured as described above operates as follows.

〓Fitting operation of the closing plate Before the closing plate 2 is locked, the lock fitting body 1 is in the third position.
As illustrated in the figure, the lock body 12 is connected to the spring 3.
The horizontal state is maintained by the force of.

As a result, the lower surface of the tip of the keyhole-shaped fitting hole 11 is closed by the tip of the lock body 12.

In this state, the locking protrusion 22 protruding from the lower surface of the closing plate 2 is fitted into the tip of the keyhole-shaped fitting hole 11.

When the locking protrusion 22 is inserted, the tip of the lock body 12, which has been maintained in a horizontal state due to the resiliency of the spring 3, is pushed downward, and as a result, the locking protrusion 22 is pushed downward. It is completely fitted into the fitting hole 11 while descending. (See Figure 4) The locking protrusion 22 fitted into the fitting hole 11 is moved in the horizontal direction in this state to move to the narrow groove part of the keyhole-shaped fitting hole 11. As a result, the locking protrusion 22 is prevented from coming off from the fitting hole 11.

When the locking protrusion 22 is moved within the fitting hole 11, the tip of the lock body 12, which had been pressed down by the locking protrusion 22, is moved by the spring 3.
It is lifted again (turned into a horizontal state) by the elastic force of the keyhole-shaped fitting hole 11, and the hole portion having a large outer diameter is closed from the bottom surface.

When the lock body 12 is maintained in a horizontal state, the locking protrusion 22 whose distal end is fitted into the distal end of the fitting hole 11 (in the direction of the hole with the smaller outer diameter) is engaged with the aforementioned distal end. Since it is prevented from moving, it is stably held within the fitting hole 11.

= Detachment of the closing plate (release of the locked state) When opening the closing plate 2 that is locked to the lock body 1, first lift the base end of the lock body 12, which is maintained in a horizontal state, upward. lift it up.

The lock body 12 whose proximal end is lifted up has its distal end lowered below the portion supported by the pivot shaft 14. (See Figure 4) When the tip of the lock body 12 descends, the fitting hole 11
The locking protrusion 22 housed inside can freely move forward because there is no obstacle to its sliding (movement). ), it can be removed freely and can be easily released.

After the engagement of the locking protrusion 22 is released, if you stop lifting the rear end of the lock body 12, it will immediately return to its original position due to the elastic force of the spring and the horizontal state will be maintained. and waits for the next operation.

[Effect of idea]

The effects of the present invention configured as described above are as follows.

(1) The lower surface of the fitting hole 11 is formed so that the tip of the lock body 12 which is pivotably mounted can be located, but when the locking protrusion 22 is inserted, the above-mentioned lock body 12 is inserted. The distal end portion can be further lowered by lowering the locking projection 22, and the locking projection 22 can be easily fitted with one touch.

(2) The fitting hole 11 of the present invention is formed into a keyhole shape by connecting a large-diameter through-hole part and a small-diameter through-hole part, so that the fitting hole 11 can be inserted from the through-hole part with a large outer diameter. The locking protrusion 22 can be prevented from disengaging by simply sliding it in the direction of the through hole with the smaller diameter without providing any other locking structure.

(3) The lower surface of the through-hole with a large outer diameter is configured to be closed by the tip of the locking body 12 which is pivotably mounted so that it can be locked in the through-hole with a small diameter. The locking protrusion 22 that is
