Description

Dead Bolt Door Lock

The present invention relates to a dead bolt type door lock that can be installed even in a frame made of a thin thickness by reducing the overall thickness while preventing malfunction of a solenoid due to residual magnetic force.

In general, a door lock device is installed on the entrance door of a place such as a house, apartment, or office to prevent unauthorized outsiders from entering the building.

Most of these door lock devices are electronic or digital door locks that automatically lock/unlock the door by an electric signal to control the occupants for the purpose of crime prevention and security.

However, the conventional digital door lock is configured so that there is no need for a separate lock operation as the door is automatically locked when a predetermined time elapses after opening the door, but it is automatically locked by the elapsed time regardless of door closing As the re-locking operation of the ruler works, a malfunction occurs in which the locker protrudes even when the door is open. If this is not done, there is a problem in security because it is possible to go out without the door locked correctly.

In order to solve the above problems, as in Korean Patent Registration No. 10-0747983 (hereinafter referred to as 'Patent Document 1'), a magnetic sensor for detecting whether the door is opened or closed and a limit switch for detecting whether the dead bolt is locked are provided. The deadbolt is locked when the door is closed correctly to maximize crime prevention and security, and the simple structure saves the manufacturing cost due to the reduction of parts. An electronic deadbolt door lock has been proposed for the purpose of improving the reliability of the product, such as shortening the working time due to easy installation.

It consists of a door plate.

In addition, a residual magnetic force removing body made of a non-magnetic material is installed at either the rear end of the actuating shaft or the bottom of the accommodating groove of the solenoid in contact with the rear end of the actuating shaft.

In addition, Korean Patent Registration No. 10-0907047 (hereinafter referred to as 'Patent Document 2') discloses a solenoid equipped with an electromagnet; an operation shaft which is inserted into the center of the electromagnet and slide-transferred by magnetic force generated from the electromagnet according to an electrical signal; The actuating piece rotated by the actuating shaft while being hinged to one side, the actuating piece spring that returns the actuating piece rotated by the actuating shaft to its original position when the power is turned off, and the deadlocking/unlocking door while being transferred back and forth by the rotating actuating piece. a main body having bolts, a dead bolt spring for returning the locked dead bolts to their original positions when the power is turned off, and a limit switch for detecting whether the dead bolts protrude by detecting the rotated actuating pieces are installed in the housing to be interlocked; In a conventional electronic deadbolt door lock comprising a door frame plate having a dead bolt transport hole together with a magnetic sensor and sealing the body with one open side to the door frame, the dead bolt communicating inward from the open side of the body At the same time as the bolt insertion groove and the actuating piece pivoting hole are formed, one end of the solenoid is screwed to the lower end of the housing of the main body so as to communicate with the actuating piece pivoting hole. At the same time as the switch insertion hole is formed, the limit switch connected to the PCB is installed and fixed so that the switch part faces downward to correspond to the central part of the actuating piece rotated inside it, and the actuating piece rotates while interlocking with the pressing action of the actuating shaft. A solenoid actuating part is provided on the outer peripheral surface of the lower end of the actuating shaft to protrude the actuating piece by rotating the actuating piece at the same time as it protrudes to the inside of the hole.

On the other hand, in the case of a conventional door lock, the control panel for applying power to the door is not always located close to the door.

That is, when the distance between the control panel and the door increases, the length of the electric wire becomes longer, and a low current is supplied by the resistance value.

In addition, the magnetic force of the solenoid and the shaft is determined by the size of the magnetic force, that is, the magnetic force line. When a material for removing residual is included between the solenoid and the shaft as in Patent Documents 1 and 2, the magnetic force prevents the formation of the magnetic force line. becomes weak, and moreover, when a low current is applied as described above, the operation of the solenoid becomes difficult.

That is, if the residual remover is disposed between the solenoid and the shaft for residual removal as in Patent Documents 1 and 2, the magnetic force is weakened when a low current is applied, making it difficult to drive.

Moreover, heat is generated by the above-described phenomenon, and this heat generation also causes a problem in that the failure rate of the solenoid is increased.

The dead bolt type door lock according to the present invention for solving the above problems forms a stopper at a position where the solenoid and the shaft do not contact and can be spaced apart so as not to interfere with the formation of magnetic force and smoothly operate even if the applied power is low power It is an object of the present invention to provide a deadbolt type door lock that can open and close the door quickly by forming quick responsiveness without delay when switching from the closed state to the open state at the same time.

Another object of the present invention is to enable smooth operation of the solenoid part even if the applied current is low power, so that the solenoid part can be smoothly operated without being affected by the residual magnetic force even if a spring having the same elastic force as that of the existing door lock is used.

Another object of the present invention is to reduce the overall size of the housing by forming the contact surface of the dead bolt in the form of a groove to a size into which a partial thickness or the entire thickness of the dead bolt operation bar of the working piece in contact with the dead bolt can be inserted. It is to achieve the effect that can be installed on the frame of

The present invention forms a stopper at a position where the solenoid and the shaft are not in contact with each other and can be separated from each other without interfering with the formation of magnetic force and smoothly operates even when the applied power is low power, and at the same time there is no delay when switching from the closed state to the open state By forming a quick response, the door can be opened and closed quickly.

In addition, even if the applied current is low power, the operation of the solenoid part is smoothly performed, so that even if a spring having the same elastic force as that of the existing door lock is used, the operation can be performed smoothly without being affected by the residual magnetic force.

In addition, by reducing the overall size of the housing by forming the contact surface of the dead bolt in the form of a groove to a size that can insert some or the entire thickness of the dead bolt operating bar of the working piece in contact with the dead bolt, installation is possible even in a thin frame It is a useful invention that can achieve possible effects.

Hereinafter, the configuration of the present invention will be described in more detail with reference to the accompanying drawings.

The present invention is installed in various doors, in particular, is inserted into the frame (F) of the door (D) made of tempered glass as shown in FIG. is composed

Such, in the present invention, the solenoid part 30 driven by magnetic force in the housing 10 and the cover plate 20 and the stopper 40 and the solenoid part 30 limiting the driving distance of the solenoid part 30. It comprises an actuating piece 50 rotating by driving and a dead bolt 60 that locks and unlocks the door D by the actuating piece 50 .

First, the housing 10 is formed in a rectangular shape as shown in FIGS. 2 to 4 , and an accommodating groove 11 is formed on one side, and a dead bolt accommodating groove 12 is adjacent to the accommodating groove 11 . is formed.

The accommodating groove 11 and the dead bolt accommodating groove 12 are connected to each other, and the lower surface has an open structure.

Next, the cover plate 20 is configured to be coupled to the open surface of the above-described housing 10 to block one side of the housing 10 , and the dead bolt receiving groove 12 of the housing 10 . A dead bolt hole 22 is formed at the formed position.

Next, the solenoid unit 30 is configured to be coupled to the receiving groove 11 constituting the housing 10 and includes a shaft receiving groove 31a on the inside, and the solenoid 31 and the solenoid 31 in which magnetic force is formed. ) consists of a shaft 32 coupled to the receiving groove 31a and sliding motion by magnetic force, and a pin 33 coupled to the end of the shaft 32 .

Next, the stopper 40 is coupled to the shaft 32 constituting the solenoid unit 30 .

Specifically, it is configured to limit the driving of the shaft 32 by coupling to an end side of the shaft 32 that is not coupled to the shaft receiving groove 31a of the solenoid 31 .

That is, the receiving groove end (a) formed in the shaft receiving groove (31a) of the solenoid 31 and the shaft end (b) of the shaft 32 inserted into the shaft receiving groove (31a) contact each other without interfering with the magnetic force. It is placed in a position that can be spaced apart so that it does not occur.

Next, the actuating piece 50 forms a pin coupling hole 51 to which the pin 33 coupled to the shaft 32 constituting the solenoid unit 30 can be coupled, and constitutes the solenoid unit 30 . The rotating hinge shaft 52 is formed so that the shaft 32 can rotate, and it is configured to include a dead bolt operation bar 53 on the other side.

Here, the pin coupling hole 51 is preferably formed in a long hole shape.

Next, the dead bolt 60 is driven in a linear direction by the rotation of the actuating piece 50, and forms a contact surface 61 in contact with the deadbolt actuating bar 53 of the actuating piece 50 on one side, A locking jaw 62 is formed in the longitudinal direction.

The dead bolt 60 is accommodated in the dead bolt receiving groove 12 of the housing 10 and protrudes to the outside through the dead bolt hole 22 of the cover plate 20 to set the lock of the door (D). is composition.

The contact surface 61 of the dead bolt 60 is made in the form of a groove, and the thickness of a part or the entire thickness of the dead bolt actuating bar 53 of the actuating piece 50 is formed to a depth into which the housing ( 10) is preferably configured to reduce the thickness.

In addition, the outer peripheral surface of the dead bolt 60 is configured with a spring (S) that is caught by the locking jaw (62).

The operation relationship of the dead bolt type door lock according to the present invention having the above configuration is as follows.

First, the dead bolt type door lock 100 according to the present invention is the dead bolt 60 formed in the cover plate 20 when the door D is normally locked as shown in FIG. 5 through the dead bolt hole 22 formed in the outside. to remain protruding.

At this time, the solenoid unit 30 receives current from the control panel C installed at a remote location by a conventional electric wire L to form a magnetic force so that the shaft end b of the shaft 32 is the shaft of the solenoid 31 . The receiving groove (31a) maintains a state of movement as much as possible in the direction in close contact with the receiving groove end (a).

In particular, in the present invention, the stopper 40 formed on the shaft 32 of the solenoid unit 30 does not interfere with the magnetic force formation between the solenoid 31 and the shaft 32 of the solenoid unit 30, the solenoid unit When the magnetic force of 30 is not formed, the solenoid ( 31) of the receiving groove end (a) formed in the shaft receiving groove (31a) and the shaft end (b) of the shaft 32 inserted into the shaft receiving groove (31a) are disposed at a position that can be spaced apart without contacting each other, , to enable the solenoid unit 30 to operate even when the applied current is low power, as well as open state in the closed state caused by the residual magnetic force in the state where the current is cut off and the solenoid 31 and the shaft 32 are attached It is possible to open and close the door quickly by forming a quick response without delay when switching to the door.

Looking at this, since the control panel (C) for supplying power is not installed in a position close to the door (D) in a typical door lock, power is supplied from the control panel (C) to the door (D) using the electric wire (L). As the length of the electric wire (L) increases, the resistance value increases, so that a low current is frequently supplied.

Here, when the configuration for removing the residual formation of the magnetic force line is between the solenoid 31 and the shaft 32, the driving force is lowered due to the magnetic force line not being smoothly formed, so that the solenoid unit 30 cannot operate at low power. In addition, when there is no configuration for removing the residual, the solenoid 31 and the shaft 32 come into contact with each other and the residual magnetic force when the dead bolt 60 is driven by the elasticity of the spring S after the current is cut off. Therefore, due to the shaft 32 does not fall from the solenoid 31, the responsiveness is slow when switching from the closed state to the open state, that is, a delay occurs, which causes inconvenience to the user, but the present invention uses the stopper 40 It is possible to solve the above problems.

In particular, even if the applied current is low power as described above, the operation of the solenoid unit 30 is smoothly performed, so even if the spring S having the same elastic force as that of the existing door lock is used, the operation can be performed smoothly without being affected by the residual magnetic force. there will be

In addition, the spring S formed on the outer circumferential surface of the dead bolt 60 maintains a compressed state between the locking jaw 62 and the cover plate 20 because the dead bolt 60 protrudes to the outside. .

Meanwhile, as shown in FIG. 5 , when the door D is opened, the dead bolt 60 is inserted into the dead bolt receiving groove 12 of the housing 10 .

That is, when a signal for opening the door D is received, the current supplied from the control panel C to the solenoid unit 30 is cut off, so that the magnetic force is removed from the solenoid unit 30 .

Here, the residual magnetic force remains in the solenoid 31 and the shaft 32 of the solenoid part 30, but in the present invention, the receiving groove end (a) of the solenoid 31 by the stopper 40 as described above. and the shaft end (b) of the shaft 32 are kept spaced apart so that the elastic force of the spring (S) acts larger than the force of the residual magnetic force.

Therefore, when the current is cut off, the linear motion of the dead bolt 60 and the rotational motion of the actuating piece 50 are made by the elastic force of the spring S, and the solenoid part by the operation of the actuating piece 50 The shaft 32 of (30) is to be made a linear motion.

On the other hand, in the present invention, the dead bolt 60 is accommodated in the dead bolt receiving groove 12 of the housing 10 and protrudes to the outside through the dead bolt hole 22 of the cover plate 20 to the door (D). In a configuration that can be locked, the contact surface 61 of the dead bolt 60 is made in the form of a groove, and the thickness of a part or the entire thickness of the dead bolt operation bar 53 of the operation piece 50 can be inserted. It is formed with a depth so that the thickness of the housing 10 can be reduced.

Therefore, when the present invention is installed on the door (D) made of the same material as tempered glass, it is possible to obtain the effect that the present invention can be easily installed even if the thickness of the frame (F) is thin.

Although the above-described embodiment has been described with respect to a preferred embodiment of the present invention, the present invention is not limited thereto, and it belongs to the present invention that it can be implemented in various forms without departing from the technical spirit of the present invention. It should be clear to those of ordinary skill in the art.
