Description

[Detailed Description of the Invention] The present invention relates to a lock, particularly a lock suitable for locks and the like.

The door of the locker is usually locked with a key each time an item is stored and locked.

However, when using a locker to deliver goods, etc., the door can normally be opened and closed freely, and after storing the goods, the user automatically closes the door without using a key. locked,
It is requested that the administrator open the door using the key.

In view of this, the present invention normally holds the engagement latch in the retreated position to allow the door to be opened and closed freely, and when locking the door, the latch can be moved forward and backward from the inside, and the door is closed automatically. The purpose is to provide a lock that can be locked.

Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

In FIGS. 1 and 2, a lock body 1 is made of sheet metal and formed into a box shape, and inside the lock body 1, a first latch 2 is fixed to one side of the lock body 1 by a conventional means with a spring (not shown). It is biased and protrudes. The first latch 2 is provided with a long hole 3 perpendicular to the direction of movement of the latch, and the lock body 1 has a horizontal portion 6 parallel to the direction of movement of the first latch 2, and a rear end of the horizontal portion. That is, the L-shaped groove 5 is formed of a vertical portion 7 that is continuous downwardly on the opposite side to the protruding direction of the first latch 2.
The latch operating knob 8 is fitted into the L-shaped groove 5 and is attached to the first latch 2 so as to be slidable along the elongated hole 3 of the first latch 2. The vertical part 7 of the L-shaped groove 5 is engraved in the lock body 1 so that when the knob 8 is in the vertical part 7, the first latch 2 is held in the retracted position, that is, in the open position. The location is set.

This allows the knob 8 to be attached to the horizontal portion 6 of the L-shaped groove 5.
, the first latch 2 can move forward and backward, and by retracting the first latch 2 and moving the knob 8 into the vertical part 7, the first latch 2 can be moved forward and backward.
is held in the retracted position.

Although not shown in Figures 1 and 2,
The lock body 1 is provided with a keyhole on the opposite surface (mounting surface) on which the L-shaped groove 5 is carved, and the first latch 2 is
When the knob 8 is in the horizontal portion 6, it is moved forward and backward by a key (not shown) inserted through the keyhole.

3 to 4 show an example in which the lock A of the present invention is applied to a locker R for delivering goods. A door 12 is pivotally attached to each storage 11 by a hinge 13 so as to be openable and closable. On the back side of the door 12, the lock A, the handle 15, and a shelf 16 for storing slips a, writing instruments b, etc. are attached, and on the front side of the door 12, a notch 17 is provided for exposing the handle 15. This allows fingers to be placed on the handle 15 from the outside. 18 is a locking tool for the handle 15; 19
is a lock fixing screw.

The handle 15 is also equipped with a second latch 20 for holding the door in the closed state when the door is unlocked. This second latch 20 has a triangular prism-shaped tip and is held with pressure so that it can come out and go out.
When the door 2 is closed, it is locked to the frame 10a of the locker main body 10 to maintain the closed state, but when the door is pulled outward, the lock is released and the door is allowed to open.

In the figure, 21 is a keyhole into which a key to be engaged with the first latch 2 of the lock A is inserted.

Next, the procedure for using the locker R will be described. In the lock A, the knob 8 is positioned in the vertical portion 7 of the L-shaped groove 5, and the first latch 2 is held in the retracted position. This causes the door 12 to close to the second latch 20
Although the door is held in the closed position by the door, the door can be opened, and the client can freely open the door, write necessary information on a slip, etc. stored in the receiving shelf 16, and store it in the storage 11 together with the goods. do. Next, push the knob 8 upward to position it on the horizontal portion 6. As a result, the first latch 2 can move forward and backward, and the door 12
When the latch 2 is closed, the latch 2 automatically closes the frame 10.
a and is locked. In other words, the client can lock the door without using a key.

The administrator of Locker R can easily open the door by inserting the key into the keyhole 21 and moving the first latch 2, taking out the stored items along with the slip, and then retracting the first latch 2 of the lock A. The knob 8 is placed in the vertical portion 7 of the L-shaped groove 5 to hold the first latch 2 in the retracted position and ready for use by the next client.

As described above, according to the present invention, depending on the setting position of the knob with respect to the L-shaped groove formed in the lock body,
The first latch can be held in a retracted position that allows the door to be opened and closed, or the first latch can be moved forward and backward, thereby automatically locking the door when it is closed. It has the advantage that it is not necessary to use a key when locking the lock, and that it is easy to handle.
