Description

Push-pull digital door lock device

The present invention relates to a push-pull digital door lock device, and more particularly, the access authentication means input unit capable of inputting access authentication means such as a password or a fingerprint is provided on the outer surface of the handle so that both the input of the access authentication means and the operation of opening the door are performed. At the same time, the handle does not have a rotary structure, but a pivoting structure in which both ends move like a seesaw around the center of the handle to open the door by simply pushing or pulling one end of the handle. In addition, the present invention relates to a push-pull digital door lock device that allows the handle to be used continuously as it is, even if the opening and closing direction of the door is changed.

Doors provided in various buildings can be divided into two types, one is a sliding door in which at least two or more doors are slidably coupled in both left and right directions in the door frame, and the other type is rotatable in the door frame. A sliding door that opens and closes by rotating or pulling the other end of the door in the width direction by rotating or pulling the other end of the door in the width direction. The main door is mainly used as a main entrance in various buildings including apartments. Used.

And the door is basically coupled to the door lock device that can lock the door as needed, the door lock device is largely divided into manual and automatic.

The manual door lock device is a door lock that locks or opens the door lock device by using a key, and a person must always have the key, and in order to open the locked door, the user must remove the key from the pocket, insert the key into the keyhole, and then turn the key. In particular, as the apartments have been widely used, digital door lock devices having various structures capable of unlocking doors without using keys have been developed and widely used.

The most common digital door lock device currently used in a general home among the digital door lock devices is a method of inputting a password which is an access authentication means. The password input door lock device includes: a mortise embedded in the door; A rotation knob coupled to the mortis by penetrating the inner and outer outer surfaces of the door, respectively; A main body coupled to the inner surface of the door and having a dead bolt driving motor, a dead bolt manual open / close switch, a battery, and a controller for controlling the driving of the motor; A password input unit coupled to the outer surface of the door; And the like.

At this time, the dead bolt (dead bolt) and the latch bolt (latch bolt) is coupled to the inside and out of the mortis so as to reciprocate the bar, the dead bolt is moved only by the motor controlled by the controller and the indoor manual open and close switch The latch bolt is only moved by the rotary knob.

When the password is input to the password input device, the digital door lock device configured as described above compares the input password with the stored password by the controller of the main body. When the retracted bar is retracted, the door can be opened by retracting the latch bolt on the door frame into the mortis while the handle is rotated.

The automatic door lock device as described above has the advantage of being very convenient compared to the manual door lock device, which must always carry the key, and when the door is to be opened, the key must be removed and returned in the state of being inserted into the key hole of the door.

However, in the conventional general digital door lock, since the access authentication means input device such as a password input device for inputting the access authentication means is separated from the handle, it is not preferable in appearance, and an input provided with a plurality of buttons for inputting a password. Since the cover is covered with an additional cover, the cover must be opened in order to enter the password, and the cover needs to be covered again after the password is entered.

In addition, there is an inconvenience in opening and closing the door because the handle separated from the access authentication means input unit is a rotary structure.

In other words, after entering the access authentication means such as password into the access authentication means input means that the access authentication means is confirmed that the door lock is released, the handle must be rotated after grabbing the handle to pull or push the handle This opens the bar, there is a disadvantage that must perform a number of unnecessary operations in the process of entering the access authentication means and opening the door.

And the door is divided into two types: the structure of the left side of the door coupled to the door frame by rotating the right side and the other side of the door by the left side coupled to the door frame, according to the opening direction of the door The handle must also have two types, which raises the problem of rising production or inventory costs.

The present invention has been made in order to solve the problems of the conventional digital door lock device having a separate access authentication means input and the handle, the rotary structure of the handle, the access authentication means input and the handle is integrated and entered An object of the present invention is to provide a digital door lock device that is not coupled to the opening cover to the input unit for inputting the authentication means input.

Another object of the present invention is to provide a digital door lock device that can open a door by simply pulling or pushing the handle without pulling the handle again in a state in which the handle is rotated after checking the access authentication means.

It is another object of the present invention to provide a digital door lock device having a handle that can be used continuously regardless of the opening and closing direction of the door.

The above object of the present invention, the housing coupled to the inner and outer outer surface of the door, and rotatably coupled to each housing to operate the latch bolt inside the mortis while being rotated by a pull or push operation can be separated into two parts It is achieved by a handle having a structure, and an electrostatic sensitive access authentication means input unit integrally coupled to the outer surface of the outdoor handle.

The push-pull digital door lock device of the present invention has the advantage that the appearance quality is beautiful because the handle and the access authentication means input unit are integrated.

In addition, there is an advantage that the door can be easily opened by pulling or pushing the handle without the need to rotate the handle after inputting the access authentication means such as a password into the access authentication means input.

And since the access authentication means input device is electrostatic sensitive, it is possible to input directly without touching the cover without removing the cover, and there is no inconvenience to cover the cover again after input, Even if the opening and closing direction of the door has the advantage that it can be used as it is without changing the handle.

The present invention relates to a push-pull digital door lock device that allows the door to be opened simply by pulling or pushing one end of the handle, rather than by pulling and pushing the handle.

The door lock device of the present invention is provided with a push-pull handle for opening the door by pulling or pushing only one end of the handle without holding the handle, and access authentication means for inputting access authentication means such as a password on the outer surface of the handle The technical features of the structure in which the input unit is integrally combined.

It is another feature of the present invention that the handle has a structure that can be separated and joined in two parts.

Push-push type digital door lock device of the present invention as described above, and the mortis installed inside the door; A pair of housings fixed to the interior and exterior outer surfaces of the door, respectively; A pair of handles for moving the latch bolt of Mortis in a state rotatably coupled to each housing; It consists of, etc. Looking at each as follows.

Mortis is a combination of dead bolts and latch bolts and various mechanical parts for moving the two bolts in the casing. The dead bolts protrude from the casing and are inserted into the lock grooves of the door frame. The door is locked, and when the deadbolt retreats into Mortis, the door is open and closed.

The latch bolt is elastically coupled to the inside of the housing so as to be reciprocated so that one end thereof is always protruded out of the housing. In the state where the dead bolt is retracted and the door is open, the latch bolt is connected to the locking groove of the door frame. If it is, the door will stay closed.

If the door is closed with the door open, the door closes as the latch bolt retracts into the mortis by the door frame when the door is closed, and when the door is completely closed, the latch bolt protrudes out of the housing by the elastic force and the locking groove of the door frame By locking the door, the door can be closed stably.

The housing serves as a support for rotatably coupling the handle, and the interior housing includes a motor, a motor driving controller, and the like, for moving the dead bolt of Mortis.

Unlike conventional door lock devices, the handle does not move the latch bolt of the Mortis directly, but moves the latch bolt stopper that prevents the latch bolt, which always protrudes out of the Mortis, from going back into the Mortis so that the latch bolt can retreat. do.

At this time, the handle is not rotatably coupled, the one end is rotated forward and backward, that is, the one end is coupled to the housing to be pushed forward or pulled back, the rear toward the housing through the housing through the mortise A rod-type rotating lever extending inwardly is provided, and when one side end of the handle is pushed or pulled, that is, rotated forward or backward, the latching bolt rotates to the left or right to move the latch bolt stopper so that the latch bolt is mortis. You can retreat inside.

In other words, it is possible to open the door by a simple operation of pushing or pulling one end of the handle as it is without opening the door by pushing or pulling the handle in a rotated state.

In addition, the outside of the indoor and outdoor handles are provided with an access authentication means input device for inputting access authentication means such as a password on the outer surface of the outdoor handle, and a dead bolt operation knob for manually moving the dead bolt on the outside of the indoor handle. At the same time, the battery is built.

At this time, the dead bolt operating knob is not coupled to the outer surface of the indoor handle and rotatably coupled to the indoor housing without being in contact with the indoor handle, but simply penetrating and protruding. The movements of the bolt operated knobs are independent of each other and do not interfere with each other.

The door provided with the door lock device of the present invention configured as described above is opened by a simple operation of pushing or pulling one end of the outdoor handle after inputting the access authentication means into the access authentication means input unit provided in the outdoor handle.

And indoors, the dead bolt operating knob of the indoor handle is manually rotated or the dead bolt operating switch is pressed to retract the dead bolt by the power of the motor, and then push or hold one end of the indoor handle as in the outdoor side. By pulling, you can open the door.

Details of the effects and the resulting effects, including the object and technical configuration of the present invention will be clearly understood by the following description with reference to the drawings showing a preferred embodiment of the present invention.

1 is a front perspective view of an embodiment of the present invention door lock device, a rear perspective view in FIG. 2, a side view in FIG. 3, a side cross-sectional view in FIG. 4, a flat cross-sectional view in FIG. 5, a dead bolt in FIG. Mortis internal structure diagram showing the state, Mortis internal structure diagram showing the state just before the dead bolt retreat in FIG. 7, Mortis internal structure diagram showing the state where the dead bolt retreat in FIG.

As shown in the push-pull digital door lock device of the present invention,

A dead bolt 11, a latch bolt 12, a latch bolt stopper 13, and the like, and a mortise 10 fixedly installed in the door D;

The mortise 10 is fixed to the interior and the outer outer surface of the door (D) is located, respectively, the interior of the dead bolt 11 driving motor (M), motor (M) control controller (C), the motor (M) of Interior and

exterior housings

20 and 20 ′ in which a connecting gear for connecting the rotating shaft and the shaft for driving the dead bolt 11 is embedded;

It is coupled to each of the housings 20 and 20 'to be elastically rotatable, and extends into the mortise 10 in a state of penetrating the housings 20' and 20 to move the latch bolt stopper 13. Rotating levers 31 and 31 'are provided on the rear surface facing the door D, respectively, and the inside and the outside handles are provided with a dead bolt operating knob 32 and an access authentication means input device 32', respectively. 30, 30 '; And the like.

In the digital door lock device of the present invention configured as described above, in a state in which the elastic body (S) is interposed, such that the two ends are rotated about the coupling portion, such that the housing 20, 20 'can be elastically rotated. The combined handles 30 and 30 ', unlike the conventional mortis, move the latch bolt stopper 13 instead of the latch bolt 12, and the latch bolt 12 is driven by the force of opening the door, not the handle. The retraction is caused by the contact force with the door frame.

That is, the rotation levers 31 and 31 'which are rotated in the left and right directions by the forward and backward rotation of the handles 30 and 30' are provided on the rear surface of the handles 30 and 30 '. Rotating levers 31 and 31 'are adjacent to the internal latch bolt stopper 13 of the Mortis 10 so that the latch bolt stopper 13 can be rotated by left and right rotation of the 31 and 31'. The first and second stopper levers 14 and 14 'in contact with each other are rotatably coupled.

In addition, one end of each of the first and second stopper levers 14 and 14 'is in contact with both sides of the latch bolt stopper 13 so that the latch bolt stopper 13 is always rotated in the same direction so that the latch bolt ( 12) makes it possible to retreat.

For example, when the pivoting lever rotates the first stopper lever 14 by pushing one end of the one handle, the front end portion of the latch bolt stopper 13 which prevents the retraction of the latch bolt 12 is rotated downward. When the first stopper lever 14 pushes the latch bolt stopper 13 and pulls one end of one handle to cause the pivoting lever to rotate the second stopper lever 14 ', the latch bolt stopper 13 The second stopper lever 14 ′ lifts the end of the latch bolt stopper 13 so that the front end portion thereof rotates downward, so that the latch bolt can retreat into the mortise.

In this case, the first stopper lever 14 may be omitted, and the rotation levers 31 and 31 ′ may rotate the latch bolt stopper 13 directly.

However, the protrusions of the latch bolts 12, which are always protruded out of the mortise 10 by the elastic force of the elastic body, are inclined in the thickness direction and inclined direction of the vertical side surface and the door perpendicular to the thickness direction of the horizontal top and bottom surfaces and the door. By having four sides of the side, the protrusions have a shape of an approximately right triangle when viewed in plan view. In this case, the inclined side surface may be a curved surface (or a fan shape having a central angle of 90 °) rather than a flat surface.

Therefore, when the door is pushed and closed with the hand on the handle of the open door, the latch bolt 12, which is in contact with the door frame without being pushed or pulled, retracts into the mortis 10 so that the door can be closed. The inclined side of the two sides of the latch bolt 12 protruding portion and the inclined side are positioned on the door frame side.

In this case, the door is opened in the vertical side direction from the inclined side of the protrusion of the latch bolt 12, and closed only in the inclined side direction from the vertical side.

That is, even if the latch bolt 12 is not retracted by the handle, the inclined side of the latch bolt 12 protruding from the mortise 10 faces the door frame, so that the door can be closed. If the latch bolt 12 is not retracted, the door cannot be opened because the vertical side of the latch bolt 12 is caught in the locking groove of the door frame.

However, in the door lock device of the present invention, the handles 30 and 30 'do not retract the latch bolts 12, but only the latch bolt stoppers 13 which prevent the retraction of the latch bolts 12 are rotated. In the case of opening the door in the vertical side direction from the inclined side of the handle 30, 30 'even if you push or pull the latch bolt 12 does not retract the door can not be opened.

However, if the vertical side hanging on the locking groove of the door frame changes to the inclined side when opening the door, the latch bolt can be retracted into the mortis so that the door can be opened.

That is, as shown in Figure 9, the latch bolt 12,

A guide casing 12A having an inner space in which a rectangular opening H is formed at one end of the longitudinal direction and the other end of the longitudinal direction is blocked;

One side end is protruded to the outside through the opening (H) in the state inserted into the guide casing (12A), but is not separated to the outside, a pair of horizontal plane (or upper surface and parallel to the direction of movement thereof) A first latch member 12B having a bottom surface) and a vertical side surface (S1, or a front and rear surface) and a pair of inclined side surfaces (S2, or both front end surfaces) inclined with its movement direction;

The other end of the first latch member 12B positioned in the guide casing 12A in the state coupled to the guide casing 12A so as to be reciprocated is inserted into the other end of the first latch member 12B so as to be rotatable. A second latch member 12C;

An elastic body 12D interposed between the second latch member 12C and the other end of the guide casing 12A to elastically protrude one side end of the first latch member 12B to the outside of the guide casing 12A; The door can be opened in the vertical side direction from the inclined side surface of the latch bolt protrusion.

At this time, the thickness of the protrusion 12B1 of the first latch member 12B protruding out of the guide casing 12A is thinner than the thickness of the built-in part 12B2 which is always located inside the guide casing 12A. The stepped portion is formed between the internal portion 12B2 and the stepped portion so that the first latch member 12B does not escape from the guide casing 12A.

The interior portion 12B2 of the first latch member 12B is exposed to the outside of the guide casing 12A in a state located inside the guide casing 12A, and flow grooves G are disposed on the upper and lower surfaces thereof, respectively. Formed structure.

Further, both front end surfaces of the first latch member 12B in the moving direction have the same inclination, and the angles between the vertical side surfaces and the two inclined side surfaces in contact with both ends of the vertical side surfaces are 35 ° to 55 ° and 155 ° to The 135 ° range is good, and the shape of the parallelogram column with the two angles of 45 ° and 145 ° is more preferred.

For the same reason, if the angle between the vertical side and the inclined side of the protrusion does not reach 35 °, the door frame is applied to the inclined side of the first latch member 12B when the door is closed because the length of the protrusion protruding from the mortis becomes longer. This may cause excessive damage to the latch bolts, and as the movement length of the protrusion increases, the mortise becomes larger than necessary.

When the angle exceeds 55 °, the length in the direction perpendicular to the direction of movement increases, the amount of rotation increases, and the operating speed becomes slow. After rotation, excessive clearance is formed between the guide casing 12A and the first. 1 because the latch member 12B is not stably hung in the blackening groove of the door frame and flows inside the blacking groove even by a small force, thereby increasing the shaking of the closed door.

And as said elastic body (D), a coil spring is preferable.

By using the latch bolt 12 as described above, the door can be opened in the vertical side direction from the inclined side of the protrusion 12B1 without directly retracting the latch bolt as a handle.

Both sides of the first latch member 12B in the moving direction, that is, the protrusion 12B1 and the interior 12B2, are provided with a vertical side surface S1 and an inclined side surface S2, respectively. ) And the two inclined side surfaces S2 are located in opposite directions along the opening and closing direction of the door, so that when the inclined side surface of the protrusion 12B1 is closer to the door frame than the vertical side surface, the interior portion 12B2 located inside the guide casing 12A. ), The vertical side is located closer to the door frame than the inclined side.

Therefore, unlike the one-way latch bolt, when the vertical side surface S1 of the protrusion 12B1 is caught in the locking groove of the door frame and the door is pulled in the vertical side direction from the inclined side, the vertical side surface of the protrusion 12B1 by the door frame. External force is applied to S1, and a force opposite to the protrusion 12B1 is applied to the internal portion 12B2 positioned in the guide casing 12A with the contact portion between the first latch member 12B and the opening H as the working point. By acting, the force acts on the inclined side surface S2 side from the vertical side surface S1 also in the case of the interior part 12B2.

That is, a force acts in the direction which rotates the 1st latch member 12B centering on the contact part of the 1st latch member 12B and the opening H. FIG.

As a result, the inclined side surface S2 of the built-in part 12B2 located in the guide casing 12A rotates to the inner surface of the guide casing 12A which is separated from the inclined side surface S2, whereby the protrusion 12B1 and the built-in part ( 12B2) The first vertical side surface S1 and the inclined side surface S2 are respectively changed to the inclined side surface and the vertical side surface, and the vertical side surface S1 of the protrusion 12B1 projected outside the guide casing 12A and caught in the door frame. As the inclined side is changed, one end of the latch bolt 12 may retreat into the mortise 10 by the contact force with the door frame.

However, the first latch member 12B has a rotatable structure, and when the door is opened, the first latch member 12B is retracted in the rotated state as described above, or the door is opened in the opposite direction as described above without being rotated. In the case of retreating with the first latch member 12B rotated, even if the handle is released, the first latch member 12B does not return to its original position, that is, protrudes from the mortise 10. The latch bolt stopper 13 does not return to its original position but remains rotated.

This is because the flow groove G of the first latch member 12B is also rotated by the rotation of the first latch member 12B. When the first latch member 12B does not return, the latch bolt stopper ( 13 is in a state in which it cannot fully rotate upward because it does not enter the flow groove G while contacting the bottom surface of the built-in part 12B2 of the first latch member 12B.

However, when the latch bolt 12 is retracted in a non-rotated state, unlike the case in which the latch bolt 12 is retracted in a rotated state, since the flow groove G is not rotated, the handle is released. The latch bolt stopper 13 immediately enters the flow groove G to return to its original position.

The operation as described above comprises a protrusion 12B1 and a built-in portion 12B2 having different thicknesses, a flow groove G is formed in the built-in portion 12B2, and is rotatable in the guide casing 12A. It is made by the structure of one latch member 12B.

That is, the upper end of the latch bolt stopper 13 is located in the flow groove G formed in the inner portion 12B2 of the first latch member 12B, and is provided in the protrusion 12B1 of the first latch member 12B. When the door is opened in the inclined side direction from the vertical side, the first latch member 12B can be retracted into the guide casing 12A by the force applied to the inclined side of the latch bolt stopper 13. The door can be opened with or without turning.

However, when the door is opened in the vertical side direction from the inclined side provided in the protrusion 12B1, the first latch member (A) is in the state where the upper end of the latch bolt stopper 13 is fitted into the flow groove G of the built-in part 12B2. Since 12B) cannot be rotated, the door cannot be opened unless the upper end of the latch bolt stopper 13 is rotated downward and moved below the flow groove G.

That is, when the upper end of the latch bolt stopper 13 is rotated downward by using the handle and positioned below the flow groove G, the first latch member 12B rotates to change the direction of the vertical side and the inclined side, and thus the first latch. The member 12B can be retracted into the guide casing 12A to open the door.

As described above, when the latch bolt stopper 13 is rotated and the first latch member 12B is retracted while the latch bolt stopper 13 is rotated, the handle is released to allow the latch bolt stopper 13 to return to its original position. Since the flow groove G of the member 12B is also rotated, the upper end portion of the latch bolt stopper 13 cannot enter the flow groove G of the first latch member built-in portion 12B2, and therefore, is completely returned to its original position. You will not be able to return upward.

The upper end of the latch bolt stopper 13 enters into the flow groove G of the built-in part 12B2 only when the first latch member 12B is fully returned and returned to its original state without being rotated. ) Can also be completely returned.

At this time, the rotation of the first latch member 12B in its original state while returning is more stable when the non-rotating state is more stable when the elastic force acts on the structure of the internal portion 12B2 separated by the flow groove G. Because.

The operation of the dead bolt 11 for locking the door is performed by the motor M and the controller C embedded in the indoor housing 20. When the locked door is opened, the dead bolt 11 is input to the access authentication means input unit 32. After the controller C checks the access authentication means, the motor M is driven to retreat the dead bolt 11 so that the door can be opened using the outdoor handle 30 '. The battery D as a power source for driving the motor M through is built in the outdoor handle 30 '.

At this time, the dead bolt 11 is indirectly driven by the motor (M), the mortise 10 is provided with a rotary lever 15 for horizontal reciprocating the dead bolt 11, the rotary lever 15 is It is rotated by the motor (M).

A stopper release lever 16 is coupled to one end of the rotary lever 15, and a dead bolt stopper 17 that prevents the retreat of the dead bolt 11 is coupled to one side of the mortis 10 so as to be rotatable. .

Therefore, when the rotary lever 15 rotates by the motor M, the stopper release lever 16, which rotates with the rotation of the rotary lever 15, pushes the dead bolt stopper 17, which has been caught on the dead bolt 11. At the same time, the rotating lever 15 reverses the dead bolt 11 to release the locked state.

By the way, the dead bolt 11 is driven by the motor (M), the motor (M) is driven by the controller (C), the controller (C) is to operate the motor (M) only after confirmation of the access authentication means , When opening the door in the room that does not need to check the access authentication means, the person must directly rotate the rotary lever 15 so that the dead bolt 11 moves.

In order to operate the rotary lever 15 in the room as described above, a dead bolt operating knob 32 is provided on the interior handle 30, wherein the dead bolt operating knob 32 is axially coupled with the rotary lever 15. Is a structure protruding simply through the interior handle 30 without contacting the interior handle 30 in a state rotatably coupled to the interior housing, the handle 30 and the dead bolt operating knob 32 Are independent of each other and do not interfere with each other.

In addition, by directly sending a signal to the controller (C) without rotating the dead bolt operating knob 32, and electrically connected to the controller (C) to operate the motor (M), the rotary lever 15 and the dead bolt (11). It is also preferable to further provide a dead bolt operation switch 33 to the interior handle 30.

However, even when the dead bolt 11 retreats into the mortis 10 and the door can be opened after a predetermined time, the door must be automatically locked after opening or closing the door. In order to lock the door to the door closed detection means 40 that can detect the closed state and transmit the door closing signal to the controller is required.

The door closing detecting means 40 may be a proximity sensor attached to the door and the door frame, respectively, and the side coupled to the door is electrically connected to the controller C.

Or a trigger 41 elastically protruding out of the mortise 10 such as the latch bolt 12 in a state coupled to the mortise 10; A trigger detection sensor 42 which detects a position of the trigger 41 that enters the interior of the mortis 10 by the door frame and transmits a signal to the controller C; The door closing detecting means 40 may be configured.

In addition, in order to determine the locking or unlocking state of the door D in addition to the door closing detecting means 40, that is, whether the dead bolt 11 protrudes out of the mortise 10 or has retracted into the mortise 10. The dead bolt detecting means 50 for detecting whether the state is also provided in the mortise (10).

In the push-pull digital door lock device of the present invention configured as described above, the housing 20, 20 'and the handle 30, 30' are sequentially coupled to the outer surface of the door, the handle 30, 30 '. When looking at the door from the front, the front area of the housing 20, 20 'is fixed to the handle 30, 30' so that the housing 20, 20 'is not hidden by the handle 30, 30'. It is aesthetically pleasing to make it larger than the area.

In addition, when a password input device for inputting a password is used as the access authentication means input device 32 'on the front side of the outdoor handle 30', the electrostatic sensitive type is more preferable than the button type in terms of beauty and convenience.
