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.

The present invention relates to a locking and unlocking device of a swing door that divides a living room and a room, a living room and a wish bar, and is separately controlled in a process of opening the swing door in a state in which the swing door is closed or locking the closed door. It relates to a swing door locking device for unlocking or locking the door to three points by the operation of rotating the handle in the upward or downward direction without using the knob.

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 pivoting body (rotating plate of the present invention) is configured to pull the latch (latch bolt of the present invention) in accordance with the pressing operation of the handle. The rack on the plate, the driven gear formed integrally with the pinion engaged with the rack, the drive gear is installed in engagement with the driven gear and rotates in accordance with the rotation of the knob installed on the outside of the enclosure and the rack is caught on both ends of the rack A pair of sliders, which are lifted and lowered together according to the lifting and lowering movements, and at the ends of which a roller is rotatably installed, and the sliders 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 is intended to naturally occur in the above two operations to only one operation, while inducing a convenient use of the swing door, while inducing three points of locking to further enhance the security of the swing door.

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 a locking device in which a latch and a strike are installed on the doorpost in a casement door and a casement door made of a doorframe, and a locking mechanism is installed in the doorframe. When the door is rotated in the direction of the doorpost, the latch bolt is Pushed backward by the strike, the latch front wing of the latch bolt rotates the rotary blade, thereby gathering the stopper's wing latch into the center of the case, and the stopper's locking projection comes out of the Laura box, where the Laura is mounted. As the ball is inserted into the roller box by the latching jaw of the latch and passes through the locking jaw, the roller is seated in the roller seat of the latch and the latch bolt is inserted into the strike box by the latch bolt spring. Rear wing and wing spring push the rotary wing The Laura through three points by interfering with the work of Laura Ward back stop will be to provide a three-point contact hinged locking device being locked automatically while back.

The current swing door is structured by a single latch bolt, and the operation of the auxiliary locking device is a separate operation. However, in the present invention, the two and three points, which are auxiliary locking devices, are operated at the same time in one operation, thereby increasing the safety.

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

In addition, while the auxiliary locking devices other than the latch bolts are moved by separate operations, that is, the locking device of two operations is used, there is an effect that the present invention can be closed and locked state of the sliding door as one operation. This has the effect of maintaining the lock even in the closed state of the door.

According to an aspect of the present invention,

The jamb 110 is attached to the latch (10) and the strike (20). This assumes the same role as the strike and strike box of the casement 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 center of gravity structure of the four-to-date structure for inserting the handle for releasing the locking device from the outside and the rotating plate (in this specification, the rotary cam 60) configured in the handle is also omitted.

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.

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

In the above description, the door holder 100 made of a plastic profile structure proposed as a modified form of a swing door made of wood has a latch 10 and a strike 20 in the direction of the door frame 110, and a strike box 21 behind the strike. And fix it using a fixing bolt.

In addition, the door frame 110 is inserted into the main body by drilling a four-sided locking device body in a square, and installs an auxiliary locking device attached to the locking device in the device installation recess 111.

At this time, although not shown in the drawing, the handle of the sliding door is installed on some side of the door frame (110)

It is inserted into the center core hole 62 of the rotary cam 51 to rotate the rotary cam 61.

Although not shown in the drawing, the handle set of the swinging door is generally fixed to some surface of the case 90, which is the locking device body with the fixing bolt through the mounting seat. Therefore, the handle mounting hole 97 shown in FIG. 2 is a part for mounting the handle.

The detailed configuration of the three-point locking device of the swing door of the present invention after the above installation process will be described with reference to FIG.

Figure 2 is a perspective view showing the configuration of a three-point locking device of the swing door of the present invention as a representative of the present invention.

The brace 10 and the square hole installed based on the doorpost airtight protrusion 101 of the doorpost 100 are perforated, and a strike box 21 is inserted into the perforated part and a strike is installed thereon. Fix firmly with bolts.

A latching jaw 11 similar to the protrusion of the door post airtight protrusion 101 is provided, and a rear seating hole 13 into which the roller 40 protruding from the locking device body is inserted is inserted. The strike 20 is also installed perpendicular to the latch bolt 70 so that when the latch bolt 70 meets the strike, the strike 20 is pushed back by the strike 20 and the strike box 21 is inserted. In addition, in order to fix the clamp 10 to the door holder 100, and having a clamp fixing bolt hole 12 to be firmly fixed to the door holder 100 using a fixing bolt.

The locking device body is installed in the door frame 110, the fixing plate 30 is configured to match the inner surface of the door frame along the device installation groove 111. The fixing plate 20 is provided with a roller protrusion 32 so that the roller 40 can be pushed in and out. The Laura protrusion 32 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 30 can also be changed in length depending on the length and characteristics of the swing door.

The rear part of the fixing plate 30 is coupled to the case 90 by fastening the fixing bolt to the fixing plate mounting hole 94 and the case fixing bolt hole 34. The upper and lower left and right sides of the case 90 is equipped with a roller 40 capable of moving backwards.

The roller 40 has a rotatable structure by inserting the roller shaft 42 into the shaft hole 41, and the roller shaft 42 is mounted on the roller holder 43 and fixed.

The roller catcher 43 has a structure for preventing the departure from the fixing plate 30 by having a cradle escape preventing wing 43a which is a wing on both sides. In addition, a pair of roller springs 44 are provided at the lower portion of the roller latch fixture 43 to move forward and backward within the roller box 45. The fixing plate locking hole 47 of the roller box 45 is inserted into the roller box insertion hole 31 of the fixing plate 30 to prevent the roller 40 from being separated. Eventually, the Laura 40 is mounted on the roller latch bracket 43 in the range of the Laura box 45 fixed to the fixed plate 30, and meets the latching jaw 11 of the latch 10 by the roller spring 44. The roller box 45 is inserted into the roller box 45 and passes through the locking jaw 11 of the clamp 10 and protrudes by the roller spring 44 to be stopped while being seated on the roller seat 13 of the latch 10.

Due to this, the swing door is seated on the protruding force of the Laura (40) and the Laura Spring (44) 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. It will not be.

In addition, the latch bolt 70 is positioned between the pair of rollers 40 and the center portion of the case 90. The latch bolt 70 is always pushed out of the case 90 by the elasticity of the latch bolt spring (74). The latch bolt spring 74 is positioned between the latch spring holder 93 and the latch bolt 70 of the case 90.

The latch bolt 70 has a sound to be inserted into the rotary locking blade 83 of the rotary blade 80, the front portion of the sound is the front portion of the latch 71, the rear portion of the latch is the rear blade 72.

This is because the latch bolt 70 meets the strike 20 and is reversed, or when the handle of the case is rotated and the center of gravity receiving the rotational force is inserted into the center of the hole 61 of the rotary cam 60 to rotate, the rotation cam ( When the latching blade 62 of the 60 rotates in the latching bolt 70 while rotating in the rotary cam seating hole 73 of the latching bolt 70, the rotating locking blade 83 of the blade spring 84 rotating blade 80 is rotated. Rotation blade (80) is inserted to rotate about the blade center hole (82) around the insertion.

This is a configuration for the front part of the rotary blade 80 and the return protrusion 81 to collect the stopper 50 in the center of the case 90 while the rotary blade 80 is rotated by the latch bolt 70.

If the pair of stoppers 50 thus collected is provided with a catching hole 52 so as to be caught by the rotary blade 80, the opposite side has a catching protrusion 51 to the stopper inserting hole 46 of the Laura Box 45. It is inserted in the structure to prevent the movement of the roller 40 or to allow the movement of the roller 40 by blocking the rear portion of the roller latch fixture 43.

In addition, the stopper 50 is provided with a wing jaw latch 53 is inserted into the return projection 81 of the rotary blade 80 to perform the function of returning the stopper 50, that is to push out.

It is located between the latch front blade 71 and the latch rear blade 72 of the protruding blade of the latch bolt 70, which is responsible for the return of the rotary blade 80, but also receives the force of the latch bolt spring 74, but the wing spring ( 84) while returning the latch bolt (70) to the protruding position always returns the rotary blade (80).

The case 90 has a blade center shaft 91 into which the rotary blade 80 is inserted and a spring mounting shaft 92 on which the wing springs 84 are mounted, and also a latch spring holder 93 and a fixing plate holder 94. And, if the cover 95 is provided to protect the internal components of the case 90, the gerber 95 and the case 90 is a rotary cam mounting hole 96 is perforated rotation of the rotary cam 60 It is a structure that can be inserted into the center.

This is when the handle of the swinging door is rotated or the swinging door is rotated so that the latch bolt 70 meets the strike 20. Thus, when the roller 40 meets the catching jaw 11 of the catch 10, the latch bolt ( 70 is inserted into the case 90.

The latch front blade 71 of the latch bolt 70 is inserted to rotate the rotary blade 80 with respect to the blade center axis 91 of the case 90, whereby the rotary blade 80 is the stopper 50 The wing catching port 52 of the latch bolt 70 is collected in the direction.

As a result, the locking protrusion 51 of the stopper 50 is separated from the stopper insertion opening 46 of the roller box 45, thereby releasing the rear of the roller 40 and the roller latch opening 43 so that the movement is free. This is the process for the door to be locked. Thus, the free movement of the Laura (40) and Loragugugu 43 is able to enter through the locking jaw (11) of the latch (10) into the Laura seat (13), the Laura box (45) and Laura again The cradle 43 is spaced apart by the roller spring 44.

At this time, the latch bolt 70 is also inserted into the strike box 21 through the strike 20. Therefore, the latch rear blade 72 of the latch bolt 70 restores the rotation catching blade 83 of the rotary blade 80, whereby the return protrusion 81 of the rotary blade 80 is the blade of the stopper 50. The jaw stopper 53 is inserted to return the stopper 50.

The stopper 50 thus returned returns the locking protrusion 51 back to the stopper insertion opening 46 of the roller box 45, thereby blocking the back of the roller fastener 43 in which the roller 40 is installed and latching bolt 70. And a pair of Laura (40) is fixed, the door is locked. When the handle of the swing door is rotated in reverse, the latch bolt 70 is separated from the strike box 21, and at the same time, the locking protrusion 51 of the stopper 50 is stopped at the stopper insertion hole 46 of the Laura box 45. It is to free the movement of the Laura 40 while exiting. This is a method for simultaneously locking three points in one operation.

As a result, it is the rotation cam 60 that governs the operation of the latch bolt 70, the governing the rotation cam 60 is the core of the handle installed on the outside of the door frame (110).

In addition, when the roller 40 is located at the roller seating hole 13 of the latch 10 by the roller spring 44 of the roller box 45, the roller latch 43 is in close contact with the fixing plate 20. Space is created inside the box 45. When the locking protrusion 51 of the stopper 50 enters through the stopper insertion opening 46 into the space of the Laura box 45 generated as described above, the door 40 is locked because the Laura 40 cannot fall. The locking protrusion 51 of the stopper 50 may be in the locked position by the latch bolt 70 and the rotary blade 80.

The latch bolt 70 always protrudes out of the latch bolt protrusion 33 of the fixing plate 30 by the latch bolt spring 74. The latch bolt 70 protruded in this way is not affected by the locking blade 62 of the rotary cam 60, and the front edge of the latch bolt 70 of the latch bolt 70 is provided because the rotary cam 60 is in the rotary cam seating hole 73. The rotary blade 80 inserted between the 71 and the latch rear blade 72 keeps the locking protrusion 51 of the stopper 50 at the stopper of the roller box 45 while keeping the horizontal by the wing spring 84. Is inserted into the insertion hole 46, to prevent the movement of the roller 40, and to keep the locked state by inserting the latch bolt 70 in the strike box 21.
