Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lock for a bag or the like that eliminates the need for a button lock on the engaging part by fixing the operating shaft of the engaging part.

In this first method, the engaging member was locked and the lock portion was unlocked, so it was extremely difficult to provide a robust lock.

In this invention, the operating shaft and the lock are integrally constructed, and the key core is fixed in the pressed state by simply pressing the key core provided in the operating shaft so as to be slidable in the axial direction. It is an object of the present invention to provide a lock for a bag, etc., which thereby prevents the movement of the operating shaft.

An embodiment of this invention will be described with reference to the drawings.
A is a secondary lock that is attached to the lid of the bag, B is a main lock that is attached to the bag body at a relative position to the secondary lock A, C is a locking mechanism installed in the main lock B, and D is a lock mechanism that is installed inside the main lock B. This is an unlocking means for unlocking the locking mechanism C.

A fitting projection 18 protrudes from one side of the secondary lock A, and 1 is a piece protruding from the back side of the projection 18, and the secondary lock A is integrally molded by Guicasting or the like. Alternatively, the bridge member may be made separately and attached to the fixed lock body,
Elastic bodies 19 are installed on both sides of the fitting convex portion 18 to reinforce the engaged state of the bridge portions.

Reference numeral 2 denotes an oval horizontally elongated hole located at a position offset from the center of the circular base 3 protruding from the surface side of the lock housing 5.

The base 3 can also serve as a support shaft when attached to the piece body, and its thickness corresponds to the thickness of the piece body.

On one side of the main fixed lock B is a convex portion 1 for fitting the sub-fixed lock A.
8 is fitted into the ninth fitting recess 20, and a notch 21 is provided in a part of the seat of the fitting recess 20 on the back surface of the lock housing 5 of the main fixed lock B. There is a sliding chamber 4 communicating with.

One side wall of the sliding chamber 4 is provided with a sliding groove 22 for the female locking plate 14 and a spring storage groove 23, and the other side wall is provided with a spring storage groove 23 which is connected to the sliding chamber 4.

Reference numeral 6 denotes a circular connecting hole bored in the bridge plate 7 that allows the sliding chamber 4 to slide freely, and the bridge portion 24 projects from the cutout portion 21 .

Reference numeral 8 denotes a cylindrical operating shaft that penetrates the oblong hole 2 from the front side and fits into the connecting hole 6. This cylindrical operating shaft 8 has a flange 25 integrally molded at its base and slides on the base 3.

The length of the shaft is such that it passes through the shaft and forms a flat surface that does not protrude from the bridge plate 7, and is caulked to the base 3.

The bridge plate 7 integral with the cylindrical operating shaft 8 is provided in the sliding chamber 4 and is biased toward one side of the sliding chamber 4 by the spring 26. It is biased to one side.

As is clear, when the main and sub-fixing locks A and B are engaged, the slope of the piece 24 of the main fixed lock B comes into contact with the slope of the piece 1 of the sub-fixing lock A.
The piece plate 7, which can be moved by pressing the sub-fixing lock A, has a spring 2.
1 until each piece comes into contact with the top of the slope without resisting 6.
Force migration.

At this time, the cylindrical actuating shaft 8 also accompanies it, and at the moment when the apex has passed, the bridge plate 7 recovers to its original position due to the elasticity of the spring 26, and the engaging portion is prevented from moving in the lateral direction by the elastic force of the spring 260. It is prevented.

The elastic body 19 prevents the engaging portion from collapsing in the vertical direction.

The above is the operation of the main and sub-lock locks A and B, but the present invention has a locking mechanism that locks this operation at the same time.
Reference numeral 10 denotes a key core that is slidably installed in the cylinder 27 of the cylindrical actuating shaft 8 in the axial direction, and is biased toward the base by a spring 29. A step 28 is provided around the key core 10 to engage with a step 28' of the key core 10 in order to prevent the key from being ejected.

The buttons and stepped portions 28, 28' are set so that the base surface of the key core 10 is approximately at the same height as the outer surface of the cylindrical actuating shaft 8 when they are engaged with each other.

This makes it easy to press the key core 10 toward the tip with a finger or the like.

The spring 29 is housed in a vertical hole 30 of the key core 10, and both ends of the spring 29 are connected to the bottom of the vertical hole and the cylindrical operating shaft 8.
They are each supported by regulating rods 32 fixed so as to cross 7.

Therefore, in a normal state, the tip of the key core 10 does not protrude from the back surface of the bridge plate 7, and only when the base of the key core 10 is pressed with a finger, etc. It moves up and down by protruding and retracting due to the repulsive force of the spring 29.

The tip of the key core 10 is formed into a tapered shape, and an annular recess 33 is provided around the base thereof.

A lock male plate 1 having a countersunk hole 34' is provided on the back side of the lock housing 5.
5 is fixed thereto, and a locking female plate having a countersink hole 34 that forms the clamping opening 13 together with the countersink hole 34' of the locking male plate is slidably provided on the back surface of the lock housing 5, and is provided with an unlocking means to be described later. It is biased toward the male locking plate 15 by a spring 16 housed in an operating piece 38.

Therefore, the locking male plate 15 is pressed against the side wall of the sliding chamber 4 in the opposite direction to the connecting plate 7 for the main fixing lock BK$-.

However, since the male locking plate 15 is pressed against the female locking plate 14 by the elastic action, the female locking plate 14
It has nothing to do with the elastic contraction effect that acts on .

A connecting piece 36 protrudes from the sliding chamber 4 on one side of the female locking plate 14, and a sliding rod 37 is integrally molded to slide in the sliding groove 22.

Although it is possible to store the spring by providing a spring storage groove in one side wall of the sliding chamber 4, it is possible to store the spring in the connecting piece 36 as shown in the figure.
It is desirable to provide a spring storage part on the base side of the spring to store the spring.

The above is the locking mechanism C attached to the main fixed lock B, but when each piece of the main and sub fixed lock is engaged, the key core 10 for clamping the lock is 11 inside the cylindrical operating shaft 8 and does not function. In addition, the tip of the cylindrical actuating shaft 8 does not act on the clamping port 13, and the male and female locking plates 14 and 15 receive elastic pressure against the sliding pressure of the bridge plate 7. Therefore, it is impossible to accompany the piece plate 7.

When the base of the clamping key core 10 is pressed in the above engaged state, the tapered tip presses against the inner diameter of the clamping opening 13 against the spring 29.

The male plate 15 for the lock is the female plate 1 for the 110 lock that holds the compression.
4 starts sliding, and at the moment when the tapered large diameter part reaches the stepped part 35 as the tip part descends, the locking female plate 1 is inserted into the recessed part 33'.
4 is fitted into the countersunk hole 34 and the locking male plate 1.
5 and the inner diameter of the countersunk hole 34'.

Thus, the clamping key core 10 protruding from the cylindrical operating shaft 8 is fixed, and the locking male plate 15 is pressed against the other side of the sliding chamber 4, so the piece attachment plate 7 is moved to the other side. Sliding is prevented.

Furthermore, the inserted state of the tip of the clamping key core 10 for the snapping action is a complete lock in which the male and female locking plates 14, 15 have the effect of pressing the root 7 surface of the piece.

Here, the engaging portion is pressurized from the horizontal, vertical, and upward directions.

As mentioned above, the unlocking means for unlocking the fully locked state will be described below. Reference numeral 17 is an operating body attached to one side of the female locking plate 14,
A spring 26 is provided on one side of the actuating piece 38 to press the other side against the housing, and the actuating piece 40 is made to protrude from a window 39 formed on the other side.

This state is the position where the lock state can be achieved, but the operating piece 3
8 and the connecting piece 36 are fixed at both ends of a connecting rod 41 of arbitrary length, so that the locking female plate 14 and the operating piece 38 are integrated.

Therefore, if the actuating piece 38 is pressed against the spring 26, the locking female plate 14 will slide on one side 1 of the sliding chamber 4, and the clamping key core 10 will be released from being clamped, and the clamping key core 10 will be released. rises and returns to the original position.

This will unlock the engaged state.

In other words, the female locking plate 14 is simply moved by sliding without using the key to unlock the lock.

In the structure according to the fortune of money, the operating shaft and the key core are integrated, but the operating shaft is affected by the operation of the key core.

However, the actuation of the actuating shaft has no effect on the locking structure.

This trade-off is achieved by making the engaging piece member and the locking clamping member separate, so that the locking female and male plates 14 and 15 are engaged with the clamping key core 10, which also prevents the sliding of the bridge plate 71. It is not something that was directly locked.

The effect of indirectly locking the piece plate 7, which is frequently operated, is extremely large in providing a robust key.

Furthermore, the fact that locking is possible by sliding the female locking plate 14 means that unlocking can also be achieved by simply sliding the iron plate, so there is no need to use a key, and the structure is simple. Complete locking during permanent use can be guaranteed.

The drawing code 42 is the back cover of the lock case 5, 43 is the screw, 44
is a screw hole.
