Description

locker lock structure}

The present invention relates to a locker locking device, and more specifically, in the process of installing a vertical lever on the locking device provided on the handle of the locker door and swinging it left and right like a pendulum, the latch connected to the lever is pulled and the door opens. At this time, the lock ring is automatically retracted through sliding contact with the lever, so the configuration required for the operation of the lock ring that restrains the lever is simplified. In particular, since the lever is composed of a single vertical piece, the design of the handle is improved. It's about improved locker locks.

In general, there are many different types of lockers used for various purposes, including gyms, schools, workplaces, and storage. Gym lockers are designed to store personal belongings such as sportswear and equipment, while school lockers are used by students to store books, backpacks and other supplies. Workplace lockers are often used by employees to store personal items, work clothes, and tools, while storage lockers are used for long-term storage of items such as seasonal equipment, excess inventory, or personal belongings. Lockers may vary in size, shape, and material depending on their purpose. Most lockers may be made of metal, while others may be made of plastic or wood. And lockers are equipped with various types of locking devices, such as padlocks, combination locks, or electronic locks.

In particular, lockers used in schools are equipped with a locking device on the door handle. Lockers with locks on the door handles have a different structure from existing lockers. Unlike regular lockers that can be opened with a lock or combination, a locker with a locking device attached to the door handle has a body that makes up the handle and is composed of a front cover and a back cover, with the front cover fastened to the front of the door and the back cover. is fastened to the front cover at the rear of the door. In addition, the rear cover is provided with a latch that is hooked to the locker to move elastically, and the front cover is provided with a lever that moves the latch. Additionally, the front cover is provided with a lock ring to secure the lever by locking it.

Previous patent No. 1765486 states that the rotary lever and the locking assembly (latch) are connected by the eccentric protrusion of the rotating lever, and the locking assembly is rotated to the left and right to release the lock by rotating the rotating lever to the left and right. However, the conventional patent is provided with a locking part that prevents the rotary lever from moving when it is locked with a lock. The locking part consists of a stator (lock ring) that locks and an operator that connects the eccentric protrusion of the rotary lever and the stator, and the lock is When the rotary lever is rotated in a locked state, the rotary lever is restrained because the operator is caught by the stator. However, since an operator is required to restrain the rotating lever, and the operator and locking assembly are slidably connected through an eccentric protrusion, the configuration is complicated and assembly is poor, and in particular, there are problems such as an increase in parts and an increase in manufacturing cost. .

Conventionally, in order to move the latch, a method was used in which the lever was reciprocated left and right or pulled back and forth to turn. Alternatively, a technique was used in which the latch was released while rotating the circular lever to the left and right. In order to prevent the lever from moving when the lock is locked, the lever and the lock were directly coupled together, or the lock ring was fixed using various parts to prevent the lock ring from moving. However, there was a disadvantage in that the assembly was poor due to the complicated configuration. .

The present invention was developed in consideration of conventional problems. The purpose of the present invention is to install a vertical lever on the locking device provided on the handle of the locker door and swing it left and right like a pendulum while the latch connected to the lever moves. The door is opened, and at this time, the lock ring is automatically retracted through sliding contact with the lever, so the configuration required for the operation of the lock ring restraining the lever is simplified. In particular, since the lever is composed of a single vertical piece, The aim is to provide a locker locking device that improves the design of the handle.

Another object of the present invention is that the lock ring is simple in construction because it is separated without being constrained by the lever. However, even if the latch of the lock is fastened, the latch is pressed until it is caught on the surface of the handle body, so the lock is locked. By forming a non-contact section on the lever so that the latch does not move even if the lever is slightly rotated, the operating pin is placed on the side of the traction groove by the non-contact section even if the lever is rotated due to a gap with the latch filled with the lock ring. The aim is to provide a locker locking device that cannot be unlocked because it cannot be touched.

The present invention is intended to provide a locking mechanism for use in school lockers, where the locking device consists of a lever, a latch and a lock ring. The lever is configured to move in a pendulum motion and includes a groove into which the operating pin of the latch is inserted. The lock ring is configured to engage the lever and prevent movement when the locking mechanism is in the locked position, and when the lock mechanism is released, the lock ring is retracted to allow the lever to move in a pendulum-like motion. During operation, when the lock is in the locked position, the padlock engages the lever and prevents movement of the lever, providing an additional layer of security as the padlock prevents unauthorized access to the contents of the locker. When the lock is released, the lock ring retracts, allowing the lever to move in a pendulum-like motion and unlock the lock. This allows users to easily access the contents of the locker. The present invention provides an improved locking mechanism for school lockers that provides an increased level of security and incorporates a padlock ring to provide an additional barrier to prevent unauthorized access to the locker while retaining the ease of use and reliability of the original locking mechanism. maintain As such, the present invention represents a significant advance in the field of school locker security and provides a structure well suited for use in a school environment.

For this purpose, in one embodiment of the present invention, the front cover and rear cover constituting the handle are disposed on the front and rear sides of the door, the front cover is provided with a lever that swings left and right like a pendulum, and the rear cover is attached to the locking jaw of the locker. A sliding guide is provided for slidingly guiding a latch that is engaged, and a latch spring is built into the sliding guide to elastically pressurize the latch. The operating pin of the latch is inserted into the traction groove of the lever so that while the lever moves. In the locker locking device in which the operating pin touches the side of the traction groove so that the latch is released from the locking protrusion, the lever is configured in a straight line and has an upper end that is away from the traction groove and is inserted into the pin hole of the front cover. A hinge pin is provided; The rear cover is provided with a ring guide part with a built-in ring spring, and the ring guide part is provided with a lock ring that elastically protrudes through the ring spring; The lock ring protrudes toward the front cover and is close to the side of the lever. When the lock ring is locked, the lock ring is restricted and the lever cannot be turned. When the lock is removed, the lock ring is locked. As the lever is retracted, the lever rotates, and at this time, the latch is released from the locking protrusion through an operating pin that contacts the traction groove.

According to the present invention, the operating pin of the latch is inserted into the traction groove of the lever that moves like a watch pendulum, and during the turning process of the lever, the operating pin touches the side of the traction groove to release the latch, and the lever is configured to be vertical. By simplifying this, there is an advantage that the design of the handle is improved. In particular, the lock ring that restrains the lever retracts through sliding contact while the lever is turning and does not interfere with the turning of the lever, which has the advantage of simplifying the configuration.

In addition, since the lock ring requires locks of various sizes to be fitted, a large hole is formed, so that the latch of the lock is fitted slightly loosely, thereby causing play. Therefore, when the lock ring is pressed with a finger in a locked state, a problem occurs in which the latch retracts until it is caught on the surface of the handle body. Therefore, when the lever is rotated, the latch can move because it rotates by the loosened clearance. However, since a non-contact section is formed horizontally in the traction groove equal to the clearance, the latch does not move even if the lever is slightly rotated in the locked state. Therefore, there are advantages such as improved product reliability.

A through hole 61 is drilled in the door 60 to cover the front cover. (10) and the rear cover (20) are in contact with each other through the through hole (61), and screws are fastened to all sides of the opposing surfaces of the front cover (10) and the rear cover (20) so that they are connected to the front and back of the door (60). A screw fastening hole 14 and a fitting hole 24 are formed on the rear side to fasten and secure. In addition, a sliding guide portion 21 is formed on the rear cover 20 to slide and guide the latch 40 that hangs on the locking protrusion 62 formed on the locker to maintain the closed state of the door 60, and the sliding guide portion The end of (21) is provided with a latch spring 42 that presses the latch 40 so that it is elastically fastened to the locking protrusion 62.

And the rear cover 20 is provided with a ring guide part 23 to allow a lock ring 50 having a hole for latching a lock to go in and out, and the lock ring 50 is inside the ring guide part 23. A ring spring 52 is built in to press it to move elastically. In addition, the front cover 10 is provided with a vertical lever 30, which serves as a handle to open the door 60. The lever 30 is provided with a hinge pin 31 at the top and is inserted into the pin hole 12 of the front cover 10, and the lever 30 swings left and right like a pendulum around the hinge pin 31. do. Additionally, the lever 30 is provided with a traction groove 32 away from the hinge pin 31. The traction groove 32 is a part into which the operating pin 41 formed on the latch 40 is inserted, and the operating pin 41 penetrates the pin outlet 11 long drilled on the left and right sides of the front cover 10. It is connected to the lever 30, and a passage 22 through which the operating pin 41 passes is drilled in the sliding guide portion 21 of the rear cover 20.

In addition, a ring entrance/exit 13 is formed through the front cover 10 so that the lock ring 50 provided on the rear cover 20 can be inserted, and the lock ring 50 has a side surface of the lever 30 and the lock ring 50. A contact inclined surface 51 is formed, and while the lever 30 is turning, the lock ring 50 is retracted in the process of friction when the inclined surface 51 touches the side of the lever 30. And the traction groove 32 is composed of a horizontal non-contact section 33 and a vertical contact section 34. Therefore, when the operating pin 41 is placed in the non-contact section 33 in the process of turning the lever 30 like a pendulum, the latch 40 does not move, and the operating pin 41 is placed in the contact section 34. In the reaching drawing, the operating pin 41 touches the side of the traction groove 32 and slides while friction occurs, and at this time, the latch 40 retreats and escapes from the locking protrusion 62 and the door 60 opens.

The assembly process of one embodiment of the present invention configured as described above is as follows. First, insert the hinge pin (31) of the lever (30) into the pin hole (12) of the front cover (10) and hang the E ring on the end of the hinge pin (31) to secure the lever (30) so that it does not fall out of the pin hole (12). Assemble it on the front cover (10). And in the rear cover (20), a latch spring (42) and a latch (40) are inserted into the sliding guide part (21) so that the latch (40) moves elastically. At this time, the free end of the operating pin (41) is installed in the passage ( 22) and passes through the pin entrance (11) and enters the traction groove (32). The lock ring 50 is assembled to elastically protrude from the ring guide portion 23 through the ring spring 52. The ring guide part 23 sequentially inserts the lock ring 50 and the ring spring 52 into the open rear, and then blocks the rear of the open ring guide part 23 with a separate stopper to secure the lock ring 50. It is built in, and an entrance hole is drilled in the front of the ring guide part 23 so that the lock ring 50 protrudes.

In the above, the lever 30 is assembled on the front cover 10, the latch 40 and the lock ring 50 are assembled on the rear cover 20, and then the front cover 10 and the rear cover 20 are connected to the door ( 60) is placed in front and behind so that the front cover 10 and the rear cover 20 face each other through the through hole 61, and then the screw fastening hole 14 of the front cover 10 is connected to the rear cover 20. It is inserted into the fitting hole 24 and the screw is fastened to the screw fastening hole 14 through the fitting hole 24, so that the front cover 10 and the rear cover 20 are coupled to the front and back of the door 60. Make it possible. At this time, the operating pin 41 is inserted into the traction groove 32 of the lever 30 through the pin entrance 11 and the passage 22, and the lock ring 50 is inserted into the front cover through the ring entrance 13. 10), and the inclined surface 51 of the protruding lock ring 50 is in contact with one side of the lever 30.

One embodiment of the present invention assembled in this way operates as follows. As shown in FIG. 5, when the door 60 is closed, the tip of the latch 40 is caught on the locking protrusion 62, and the lock ring 50 is fitted with a lock latch. Therefore, since the lock ring (50) is caught in the latch, it is not pushed toward the rear cover (20) and remains protruding toward the front cover (10). When the lever (30) is turned to one side like a pendulum, the lock ring (50) ) and can no longer move, so the latch 40 is in a stationary state.

In particular, the latch hole of the lock ring 50 is made larger than the diameter of a typical standard latch because the size of the latch of the lock varies. Therefore, since the latch is loosely hung in the latch hole, when the lock ring 50 is forcibly pressed, it retracts slightly by the loosened clearance, and the lever 30 rotates by the clearance. At this time, the operating pin 41 does not affect the latch 40 because it is placed in the non-contact section 33 of the lever 30.

As shown on the right side of Figure 5, when the latch of the lock is separated from the latch hole of the lock ring 50 and the lock is removed from the lock ring 50, the restraint of the lock ring 50 is released. Therefore, when the lever 30 is pushed by hand and rotated like a pendulum, the inclined surface 51 of the lock ring 50 rubs against the side of the lever 30, and the lock ring 50 is retreated, and at this time, the ring spring 52 is compressed. . In addition, the operating pin 41 passes through the non-contact section 33 and is placed in the contact section 34, so the operating pin 41 rubs against the side of the traction groove 32, and at this time, the latch 40 retracts and the latch spring 42 ) is compressed, the latch 40 is released from the locking protrusion 62, and the door 60 is opened.

As described above, the present invention consists of a simple configuration in which the lock ring is retracted in the process of contact between the lever 30 and the lock ring 50 through friction, and in particular, there is a gap between the lock ring 50 and the latch of the lock. As a result, even if the lever 30 moves, the operating pin 41 is placed in the non-contact section 33, so it does not affect the latch 40, which has the advantage of improving reliability.
