This is about a technology that allows only the lock to be removed separately.

In general, lockers are personal facilities placed in places where many people enter, such as kindergartens, elementary, middle, high schools, universities, schools, hospitals, sports facilities, saunas, subway stations, libraries, etc. to store users' personal belongings. do.

In order to prevent the items stored in these personal lockers from being lost or exposed to others, the locker door must be locked with a lock that can be locked or opened.

Due to the nature of lockers, they are used for a certain period of time and then allowed to be used by other people. In this case, of course, the lock used by the individual must be removed from the locker. However, in places such as schools, if a student leaves school without removing the lock in situations such as a sudden transfer, leave of absence, or graduation, there is a problem in that the locker cannot be used due to the lock already being used.

If the lock is locked like this, there is a way to open it through a locksmith, but in the case of locks that require numeric input or complicated locks, there are inconveniences such as having to use a separate cutter or disassemble the locker door.

As a prior art to solve this problem, Registered Patent No. 10-2503421 (locking device that can separate the lock from the door during emergency release) includes a case, which is placed within the case and inserted into the deadbolt groove of the door frame by a first spring. A deadbolt part including a movable hole and a first ring coupling groove on the inside, a lever part for moving the deadbolt part, first and second ring parts, and a master coupled to the case. A rotary link that is connected to the key part and the master key part and rotates together when the master key part rotates is placed in contact with the sliding block of the second ring part, and controls the sliding of the second ring part by moving up and down in a straight line when the rotary link rotates. A technology consisting of an operating part composed of movable members has been known.

The above prior art is a technology in which a pair of locking pieces, which should normally be fixed, are movably installed to remove the lock. However, it is structurally very complex and has the problem of increasing the number of parts, which may cause further malfunctions.

In the prior art, if the elasticity of the spring that pushes the locking piece to the correct position decreases, the gap in the locking part inevitably widens, so there is a problem that the lock may be separated by another person when used for a long period of time. When removing the lock using the master key, there is an inconvenient problem in use because the lock piece must be pulled out by pushing in one direction.

The student locker, in which the lock can be removed from the lock handle of the present invention, is configured to open the locker door by operating a lever when opening the locker door, and lock the locker to prevent the lever from operating when storing items, thereby preventing the locker door from being opened. In other words, the lock suppresses the operation of the lever, making it impossible to open the door.

Therefore, the present invention is a problem that occurred in existing lockers, such as when the lock password is lost or the key is lost when the lock is locked, or when the locker user changes schools or cannot be contacted, a hacksaw or cutter is used. This is about a technology that can easily remove a lock using a separate master key to avoid the inconvenience of removing the lock.

The present invention relates to a locker including a locking handle as shown in FIGS. 1 and 2, wherein the locking handle includes; It is installed on the door of the locker, and a key installation hole 110 is formed on one upper side, and a guide slit 120 is formed horizontally in the lower part of the key installation hole 110, and in the section where the guide slit 120 is formed. A main body 100 in which a locking piece 130 is formed, an opening/closing lever 200 installed at the front of the main body 100 to enable angle rotation, and an opening/closing lever 200 installed at the rear of the main body 100 to open and close the main body 100. The door is locked and opened and closed by a lever 200, and a ring portion 342 protruding in a ring shape is provided on the front, exposed through the guide slit 120, and includes a lock assembly 300 that is horizontally movable and , a key assembly 400 installed in the key installation hole 110 and making only the ring portion 342 independently movable by the operation of the master key inserted into the lock assembly 300 installed at the rear portion; It is characterized by being composed.

The main body 100 of the present invention is installed embedded in the door of a locker, and an opening and closing lever 200, a lock assembly 300, and a key assembly 400 are installed on the main body 100, and the front of the main body 100 A cover 140 that prevents the opening/closing lever 200 from being separated and has a closing function is further coupled to the portion.

The main body 100 of the present invention has a key installation hole 110 formed on one upper side so that the key assembly 400 can be installed, and a guide slit 120 is formed horizontally at the bottom of the key installation hole 110. It is done. The guide slit 120 corresponds to a long hole through which the ring portion 342 of the locking assembly 300 is exposed to enable horizontal movement, and a locking piece 130 is formed on the section where the guide slit 120 is formed. It is done.

In addition, the locking piece 130 protrudes integrally with the main body 100, so that the position of the locking piece 130 is fixed. In other words, the ring portion 342 itself is formed in a structure that allows the lock to fall off, but the lock piece 130 formed at a fixed position prevents the lock from falling out of the ring portion 342, so the lock is fastened. The goal is to prevent the locker door from opening.

In addition, the locking piece 130 is cut up and down to match the shape of the guide slit 120 so that the ring portion 342 can enter between the locking pieces 130 when the opening and closing lever 200 is operated.

The opening/closing lever 200 is installed on the front part of the main body 100 to enable angle rotation, and power is transmitted according to the operation of the opening/closing lever 200 to open and close the lock assembly 300. . The opening and closing lever 200 is configured to only rotate at an angle at a fixed position, and is configured to adjust the opening and closing lever 200 according to the movement path of the ring portion 342 to prevent interference with the ring portion 342 passing through the opening and closing lever 200. A cutting groove 210 is formed at the upper end of.

The locking assembly 300 of the present invention is installed on the rear part of the main body 100 as shown in FIG. 3. It corresponds to the inside of the locker door, and the ring portion 342 of the lock assembly 300 is exposed to the front through the guide slit 120. At this time, the ring portion 342 moves horizontally by the operation of the opening and closing lever 200.

To describe the configuration of the locking assembly 300 in more detail, as shown in FIGS. 4 and 5, a case 310 is installed on the rear part of the main body 100 and has a cutout 311 at the top; , a lock latch 320 that is installed to be horizontally movable on the case 310 and moves horizontally according to the operation of the opening/closing lever 200, and a lock latch 320 installed inside the case 310 to lock it. A spring 330 that pushes in the direction is installed inside the case 310 and is combined with the lock latch 320 to move horizontally together with the movement of the lock latch 320, but independently on the lock latch 320. A ring bundle 340 that is horizontally movably coupled is assembled.

The case 310 is coupled to the rear part of the main body 100 through screws, and serves as a housing in which the lock latch 320, spring 330, and ring assembly 340 are installed. A cutout part 311 is formed in the upper part of the case 310 so that the ring bundle 340 can be smoothly coupled, and the ring part 342 can be moved horizontally along the cutout part 311. .

The lock latch 320 moves horizontally to open and close the locker door, and a lever hole 321 through which the opening and closing lever 200 is inserted and power is transmitted is formed on the front part, and the lever hole 321 is formed. On one side, a guide hole 322 is formed through which the ring portion 342 of the ring bundle 340 penetrates so that only the ring portion 342 can be moved horizontally.

That is, the ring bundle 340 installed in the lock latch 320 of the present invention is installed to be horizontally movable together with the lock latch 320, but through the ring portion 342 exposed to the guide hole 322. Only the ring bundle 340 has a structure capable of independent horizontal movement along the hole of the guide hole 322.

As shown in FIG. 5, the ring bundle 340 of the present invention is formed to protrude in a ring shape from the body block 341 and the front part of the body block 341 and is exposed to the front part through the guide hole 322. The ring portion 342 and the operating ring 343, which protrudes from the upper part of the body block 341 and are exposed above the cutout portion 311 of the case 310, are formed in an integrated structure.

The body block 341 is mounted on the lock latch 320 and is installed to be horizontally movable. The body block 341 is located in the seating groove 323 formed at the rear of the guide hole 322 of the lock latch 320. It is installed in a seating structure. And, as described above, the ring portion 342 is horizontal with the lock latch 320 according to the operation of the opening/closing lever 200, and is formed in a semi-ring shape, so the ring portion 342 itself cannot be locked and the locking piece cannot be locked. The lock can be locked when located at a certain distance from (130).

And because the operating ring 343 is also integrated with the remaining components, it moves horizontally together with the body block 341. However, the operating ring 343 is exposed to the outside of the case 310 and is affected by the locking assembly. The operating relationship of the operating ring 343 will be further explained along with the configuration description of the locking assembly 300.

The spring 330 is installed inside the case 310 to push the lock latch 320 in the locking direction. As the lock latch 320 moves horizontally by the spring 330 to open and close, the ring assembly 340 installed on the lock latch 320 also moves horizontally.

The key assembly 400 of the present invention is installed by inserting into the key installation hole 110, includes a key rotating part 410 that rotates by a master key, and is formed on the rear part of the key rotating part 410 to control the master key. It consists of a stopper bar 420 that rotates together with the rotation and operates in a state of contact or non-contact with the ring bundle 340 to adjust the movement area of the ring bundle 340.

The key rotation unit 410 can be rotated only by a separately provided master key, and as the key rotation unit 410 rotates, the stopper bar 420 also rotates. The stopper bar 420 supports the operating ring 343 of the ring bundle 340 described above and has a function of preventing the ring bundle 340 from moving further in the supported direction, and when removing the lock, the master key is used. By rotating the stopper bar 420 so that it does not support the operating ring 343, the ring bundle 340 can be further moved. In this state, the lock can be removed by moving the ring bundle 340.

The operating process of the present invention as described above will be explained according to each situation with reference to the drawings as follows.

First, in normal times, as shown in Figure 1 or Figures 3 to 4, the opening/closing lever 200 is not rotated, and at this time, the open portion of the ring portion 342 is in a position blocked by the locking piece. , the lock can be locked as shown in Figure 1. At this time, as shown in the drawing, since the operating ring 343 is supported by the stopper bar 420, the ring portion 342 cannot be forcibly moved.

Then, when the door is opened without a lock, the opening/closing lever 200 is rotated as shown in FIGS. 6 and 7. At this time, the angle-rotated opening/closing lever 200 moves the lock latch 320 horizontally in the direction of the spring 330 so that the door can be opened. In this state, since there is no lock, there is no structure blocking the ring portion 342.

Also, in this state, the spring 330 is compressed, and when the opening/closing lever 200 is released again, the opening/closing lever 200, the lock latch 320, and the ring bundle 340 are moved by the restoring force of the spring 330. It will return to its original position.

If no problems occur, it can be used in the above state. However, as explained earlier, when the lock cannot be opened for various reasons while the lock is in place, the lock must be removed because the locker cannot be used at all until the lock is removed. .

In this situation, a separately provided master key is used as shown in FIG. 8. When the master key is used, as shown in FIGS. 9 and 10, the key rotation unit 410 rotates and the stopper bar 420 also rotates. In this process, the stopper bar 420 becomes non-contact with the operating ring 343 of the ring bundle 340, that is, in a non-interference state, and the ring bundle 340 becomes movable.

Therefore, as shown in FIG. 8, the ring portion 342 exposed on the front is moved by hand to further widen the gap between the ring portion 342 and the locking piece 130, allowing the lock to be removed through the gap. It will exist. At this time, the range in which the ring portion 342 can move is equal to the distance of the guide hole 322 formed in the lock latch 320.

After removing the lock, you can rotate it back to its original state using the master key.

11 to 12 show a second embodiment corresponding to another embodiment of the locking assembly 300 according to the present invention, and the shape of the ring bundle 340 includes a body block 341 and a ring portion 342. It consists only of and further includes a triangular block 350 coupled to the lock latch 320 along with the ring bundle 340.

The triangular block 350 is seated in a triangular groove 360 formed to correspond to the triangular block 350 on the rear part of the lock latch 320, and the inclined surfaces of the triangular block 350 and the triangular groove 360 are locked. It is inclined upward in the locking direction of the latch 320.

The triangular block 350 is maintained in contact with the body block 341 of the ring bundle 340, and the triangular block 350 and the ring bundle 340 are normally moved together with the lock latch 320. .

The operation process of the locking assembly 300 applied in the second embodiment will be described as follows.

In normal times, as shown in FIG. 13, the triangular block 350 is maintained accurately inserted into the triangular groove 360, and the ring bundle 340 and the triangular block 350 move together. In this state, because the stopper bar 420 of the key assembly is pressing the upper part of the triangular block 350, only the ring bundle 340 cannot move independently.

Then, when the master key is used to remove the lock, the stopper bar 420 rotates as shown in FIG. 14, and the triangular block 350 can be moved by the ring bundle 340. That is, when the ring portion 342 is held and moved in the direction of the triangular block 350, the triangular block 350 is pushed by the body block 341 and rises upward along the slope of the triangular groove portion 360. In other words, as the triangular block 350, which blocks the movement of the ring bundle 340, moves up the slope, the ring portion 342 can be moved, thereby allowing the lock to be removed.

In the above, the present invention has been described with reference to the above embodiments, but of course, various modifications are possible within the scope of the technical idea of the present invention.
