Description

3 point lock for opening door {3 point lock for opening and closing door}

The present invention relates to a locking device of a swing door that is opened and closed by pulling or pushing in an entrance or a window of a building.

More specifically, this allows the door to be kept closed and the door can be opened at any time without the operation of the lever or the handle. To the three-point lock on the swing door to keep it locked.

In general, the swinging door that divides the living room and the room, the living room and the wish bar is provided with a lock to prevent intrusion from the outside while the door is closed.

Most swing doors use a single lock. However, in order to further protect the interior from outside intrusion, the case of the door lock of the registered utility model 20-0271060 is outside the case of the door lock made of one locking device (in the Laura latch of the present invention) fixed to the door. The latch bolt is elastically installed with a spring, and the rotating body (rotating plate of the present invention) is configured to pull the latch (latch bolt of the present invention) according to the pressing operation of the handle, and the plate is installed in the housing so that it can be raised or lowered. Of the rack, a driven gear formed integrally with the pinion engaged with the rack, a drive gear installed to be engaged with the driven gear and rotating together with the rotation of a knob installed on the outside of the enclosure, In accordance with the lowering movement, the lifting and lowering movement together, and a pair of sliders rotatably installed at the end and the slider, Casement, characterized in that consisting of a locking panel for guiding the lifting and lowering of the slider supporting the door, and a locking member that is fixed to the upper and lower portions of the door frame to maintain or unlock the door according to the slider's lifting and lowering The door lock is provided.

In the case of the swing door locking device is the same principle and operation to lock the swing door using a latch bolt appearing in the lock of the general swing door. However, in the case of the roller and the locker that maintains the lock, the knob is rotated counterclockwise, so that the driven gear moves the rack to push the slider upwards and on both ends of the slider. It works by inserting the installed roller into the enclosure.

It does not induce locking door at once and locking and opening of the latch bolt is controlled by the handle, and locking of the roller is controlled by the knob. That is, the door is locked and opened by two movements. In the end, one lever is used to select the structure and method of operation that induces one direction to open and the other to lock.

However, the present invention has been devised to increase the security of the swing door by inducing two points of locking if necessary, while inducing a convenient use of the swing door by allowing the above two operations to occur naturally.

In order to actively solve the above problems, the present invention,

It has the same structure as the lock of the door, but sets the closing range of the door to 3 points. This is in the locking device that is installed on the door jamb and the locking mechanism is installed on the door frame in the swing door consisting of the door jamb and the door frame,

It is equipped with a roller which can be moved forward and backward by the roller shaft by the roller shaft, and the roller is moved backward by the latch, and the roller is moved forward while the door frame is fixed to the door jamb. In this case, the door is kept closed. This is because it is more likely to remain closed than to induce a characteristic lock of a typical swing door. However, in order to prevent the locking device installed on the door frame and the door holder from being opened, when the right turn plate is rotated by using a crust attached to a samurai or a handle, the right turn plate gear reverses the left turn plate gear, and the left turn plate gear and The right turn plate gear moves the stopper, which blocks the back of the roller lagging device in which the roller is installed, thereby inhibiting the movement of the locker. This is also a configuration to cope with the situation that requires the locking of the swing door for outing and other reasons.

As described above, the present invention can lock the swing door to three points, thereby increasing the security of the swing door from external invasion, and the swing door column by firmly fixing the two doors to the door frame, Or it can be prevented from being deformed by moisture.

In addition, because the auxiliary lock devices other than the latch bolt is moved by a separate operation, that is, the locking device of the second operation is used, the door is opened when the sliding door is pushed or pulled at any time because the present invention keeps the door closed. It has the effect of closing.

In addition, when several people work and live in the interior of the building, the door is unlocked by unlocking the door.

According to an aspect of the present invention,

Door hinge 110 is attached to the latch (10). This is similar to the strike and strike box of the swing door. In addition, the door frame 110 may be generally viewed as a swing door. The device installation recess 111 of the door frame 110 is an invisible device in a wooden door, which is shown in a profile structure made of plastic. However, it can be seen in the same way as the structure of a normal wooden door.

In addition, in the drawings of the present invention, the core structure of the quadrangular to date type structure for inserting the handle for releasing the locking device from the outside and the rotating plate (in this specification, the right rotating plate 51) configured therein is also omitted from the drawings.

If the handle of a conventional swing door lock is composed of a lever on the outside, it has four angles on one side of the lever, and the angle is inserted into the center insertion hole of the rotating plate to rotate. Because it is a structure.

Therefore, in the present specification, the handle and the shell are described in a general use example without referring to the diagram in the description.

DETAILED DESCRIPTION Hereinafter, the present invention will be described with reference to the accompanying drawings.

The fixing plate 20 is provided with a roller protrusion 22 so that the roller 30 can be pushed in and out. Lora protrusion 22 may be made of three to a plurality of configurations depending on the length of the swing door. In addition, the length of the fixed plate 20 can also be changed in length depending on the length and characteristics of the swing door.

The rear part of the fixing plate 20 is coupled to the case 60 by fastening the fixing bolt to the fixing plate mounting hole 62 and the case fixing bolt hole (23). The upper and lower left and right sides of the case 60 is equipped with a Laura 30 that can move backwards.

The roller 30 has a rotatable structure by inserting the roller shaft 32, and the roller shaft 32 is fixed to the roller holder 31 by being mounted.

The roller catcher 31 has a wing on both sides, and has the structure which prevents the departure | separation to the outside of the fixing plate 20. As shown in FIG. In addition, a pair of roller springs 33 are provided at the lower portion of the roller latch bracket 31 to move forward and backward in the roller box 34. The fixing plate locking hole 36 of the roller box 34 is inserted into the roller box insertion hole 21 of the fixing plate 20 to prevent the roller 30 from being separated. As a result, the Laura 30 is mounted on the roller latch bracket 31 in the range of the Laura box 34 fixed to the fixing plate 20, and meets the latching jaw 11 of the latch 10 by the roller spring 33. The roller box 34 is inserted into the roller box 34 and protrudes by the roller spring 33 while passing through the clamping jaw 11 of the clamp 10 so as to be seated in the roller seat 13 of the latch 10.

Due to this, the swing door is seated on the protruding force of the Laura 30 and the Laura Spring 33 and the Laura seating opening 13 of the clasp 10 so that the swing door is closed and thus the door does not open unless external force is applied thereto. It will not be.

Controlling the operation of the stopper 40 is the chief of the handle or samutton of the handle installed on the outside of the door frame 110.

Samuton is a kind of small handle that does not perform the function of the handle but only the locking function and the unlocking function. However, the center of gravity of the handle or the center of gravity of the samuton play the same role, so they are expressed in the same function.

When the core is installed outside the door frame 110 and inserted into the center insertion hole 52 of the right turn plate 51, the right turn plate gear 51a of the right turn plate 51 rotates to the left turn plate of the left turn plate 50. The gear 50a is rotated in the opposite direction. In addition, it is inserted into the gear grooves 42 of the pair of left and right symmetrical stoppers 40 on some surfaces of the left turn plate gear 50a and the right turn plate gear 51a to horizontally move the stopper 40. .

That is, when the core is inserted into the center insertion hole 52 and rotates counterclockwise, the right rotating plate gear 51a rotates the left rotating plate gear 50a in the clockwise direction. Again, the bypass front gear 51a and the left turn plate gear 50a rotate in opposite directions, and the stopper 40 moves horizontally in the gear groove 42 of the stopper 40 into which the right turn plate gear 51a is inserted. ) Is gathered into the central portion of the case 60, whereby the locking protrusion 41 of the stopper 40 is separated from the roller box 34, the movement of the roller 30 is free.

If it is rotated in reverse, the stopper 41 of the stopper 40 is inserted into the Laura box 34, which prevents the movement of the Laura 30, thereby locking the door.

Mounting the stopper 40, the right turn plate 51 and the left turn plate 50 to perform this operation is the case 60. The case 60 is provided with a case roller box 63 for mounting the roller 30 in the direction of the fixed plate 20, and a pair of stoppers 40 are placed at the rear part thereof, and a left turn plate is located behind the stopper 40. While 50 and the right turn plate 51 is placed, the rotation plate mounting hole 61 of the case 60 and the rotating plate cover mounting hole 71 of the case cover 70 are configured.
