The present invention relates to a sliding door unlocking device for releasing a locked state of a sliding door installed between a living room and a bar. More specifically, the sliding state of the sliding door can be automatically released by simply pushing the handle in the opening direction of the sliding door. It relates to a unlocking device of the sliding door.

In general, the sliding door partitioning the indoor and outdoor is provided with a locking device to prevent entry from the outside while the door is closed.

In the conventional sliding doors, the locking ring and the locking piece are respectively fixed to the overlapping part of the door so that the locking ring can be hooked to the locking piece in the closed state to act as a locking device.

However, such a locking device, depending on the locking ring and the fixing position of the locking piece and the degree of assembly of the door can be hooked to the locking piece, or can not be hooked.

In other words, if the fixing position of the hook and the hook is incorrect, or the assembly of the door is poor, the hook may not be caught on the hook, and the parts of one of the hook and the hook may be inadvertently in use. Even if broken, there was a closure that does not act as a lock.

In addition, a separate handle had to be attached to the door for smooth opening and closing operation apart from the locking device.

Therefore, in view of the above problems, a locking device that simultaneously performs a handle and a locking role has been developed by the applicant and has been registered in Korean Patent No. 633005.

Figure 1 is an exploded perspective view showing an embodiment of a conventional sliding door locking device and Figures 2a and 2b is a coupling state of Figure 1, the space portion 14 in communication with the horizontal incision groove 13 in the upper portion of the housing 12 ) Is formed and a vertical incision groove 16 communicating with the receiving space 15 is formed at the orthogonal point of the horizontal incision groove 13 which is horizontally connected to the space.

The pusher 17 having the jaw portion 17a and the neck portion 17b is elastically installed by the first elastic member 18 in the space portion 14 so as to be sunk through the horizontal incision groove 13. The operating piece 19 is elastically installed by the second elastic member 20 on the vertical incision groove 16 by the second elastic member 20 and moves up and down according to the pressing operation of the pusher 17. The horizontal surface 19a is configured to be connected to the seating surface 12a located below the housing 12.

As described above, the striker 21 when the operating piece 19 is located at the top dead center is exposed to the outside of the housing 12 to the operating piece 19 that is elastically installed by the second elastic member 20 and moves up and down. Hook 22 is formed integrally, and when the operation piece 19 is located at the bottom dead center at the point where the hook and the predetermined interval are located, it is caught and supported by the jaw portion 17a of the pusher 17 When positioned at the point, a projection 23 having a cutout 23a fitted to the neck 17b is formed, and a latching jaw having a latching groove 25a to which the latch 24 is caught to one side of the projection. 25 is formed.

In addition, the guide pin 26 is fixed to the housing 12 to which the operating piece 19 is connected, and a vertical long hole 27 is formed in the operating piece 19 to which the guide pin is fitted. The operating piece 19 moves stably during the up and down movement.

A coupling groove 24a is formed in the latch 24 for releasing the locking state of the sliding door to cover the cover 29 on one side of the housing 12 and fasten with a fastening member 30 such as a bolt. The coupling groove is fitted with a coupling pin fixed to the handle (not shown).

Therefore, while the locking state of the sliding door 31 is released by the key 28 and the sliding door is opened, the latch 24 remains horizontal as shown in FIG. It is located at the bottom dead center while compressing the elastic member 20, and the horizontal surface 19a of the operating piece 19 is connected to the seating surface 12a of the housing 12.

Accordingly, the pusher 17 located in the space portion 14 is advanced by the first elastic member 18 so that the tip portion is exposed to the outside of the housing 12, so that the protrusion 23 formed in the operating piece 19 is formed. The upper surface is held in a state of being caught by the jaw portion 17a of the pusher 17.

In this state, even if the operating piece 19 is forcibly raised, the upper surface of the projection 23 is placed on the jaw portion 17a of the pusher 17, and thus the position of the operating piece is not changed. There is no fear that the hook 22 exposed to the outside of the) may strike the striker 21.

When the pusher 17 is exposed to the outside of the housing 12 and the sliding door 31 is closed while the operation piece 19 is located at the bottom dead center, the door 17 is fixed to the door holder 37 at the time when the sliding door is almost closed. Since the pusher 17 is pressed by the striker 21, the pusher is accommodated in the housing 12 while compressing the first elastic member 18.

When the pusher 17 is accommodated inside the housing 12, the jaw portion 17a of the pusher 17 is pushed into the space portion 14, and the protrusion 23 formed on the operating piece 19 is locked. Since the operating piece 19 is raised by the restoring force of the second elastic member 20, the protruding portion 23 is located in the receiving space 15, so that the operating piece 19 of the operating piece 19 as shown in FIG. The hook 22 is caught by the striker 21 to maintain the locked state.

As described above, when the operating piece 19 is raised to the top dead center by the second elastic member 20, the latch 24 is positioned under the latch jaw 25, so that the operating piece 19 is raised. In the process of forcibly rotating by a predetermined angle in the state that the operating piece 19 is located at the top dead center end of the latch 24 is fitted into the engaging groove 25a formed in the latch jaw (25).

Accordingly, even if the operating piece is forcibly lowered to release the locking state of the operating piece 19, the end of the latch 24 is caught in the locking groove 25a of the latch jaw 25, so that the operating piece 19 Will not move.

In this state, in order to open the sliding door, the locked state of the sliding door must be released. In this case, the locked state of the sliding door is automatically released by simply turning the knob clockwise.

That is, when the handle is rotated in the clockwise direction, the latch 24 is rotated together by the coupling pin fixed to the handle, so that the operating piece 19 is forcibly lowered while compressing the second elastic member 20.

Accordingly, the pusher 17 accommodated in the space 14 while compressing the first elastic member 18 is exposed to the outside through the horizontal incision groove 13 by the restoring force of the first elastic member 18. The jaw portion 17a of the pusher 17 supports the upper surface of the protrusion 23 formed on the operating piece 19 so that the locked state of the sliding door 31 is released, so that the user can open the sliding door.

However, in the conventional sliding door unlocking device having such a structure, the locked state of the sliding door is released according to the rotation of the latch, and when the closing door is closed, the pusher is pressed by the door holder to maintain the locked state of the sliding door, thereby keeping the room safe from outside intruders. Although it has the benefit of protection, several problems have arisen:

First, the play occurred in the handle according to the processing and assembly tolerances of the coupling pin and the coupling groove formed in the latch.

Second, since the handle had to be pushed down and pressed against the resilient piece that was elastically installed to the second elastic member, the housewife or the elderly who had weak wrists needed much power to open the living room sliding door of the heavy body.

Third, the coupling pins installed on the handles and the assembling portions of the coupling grooves formed on the latches were easily worn due to the repeated flipping operation of the handles.

The present invention has been made to solve such a conventional problem, to improve the installation structure of the handle to release the locked state of the sliding door by the operation of pushing the opening direction of the sliding door without lifting the handle. There is this.

According to an aspect of the present invention for achieving the above object, by engaging the door holder and the striker fixed to the inside of the housing, or by elastically installing the operating member is released by the latching state to be lowered according to the rotation of the latch and one end of the operating member It has a stopper member for maintaining a state in which the catch is released from the striker, the guide hole is formed in the upper and lower, fixed to the sliding door, the middle portion of the power transmission means for converting the linear movement of the handle into rotational movement A second bevel gear, which is installed in the through-hole and the main body having a through-hole through which the parts are accommodated, and the second bevel gear so as to rotate the latch while rotating with the force transmitted by the power transmission means according to the movement of the handle.

Each of the accommodating spaces 44 and the accommodating space, each of which is formed in the middle portion, the accommodating space (pinion and first bevel gear installed in the same shaft) of the power transmission means for converting the linear movement of the handle 43 to the rotational movement Through hole 45 is formed.

In the through hole 45 formed in the main body 41 so as to pass through the accommodation space 44, the latch 24 can be rotated while rotating with the force transmitted by the power transmission means according to the movement of the handle 43. The rotating body 46 having the second bevel gear 47 and the engaging portion 46a is coupled, and the engaging portion 46a of the rotating body 46 exposed to the rear surface of the main body 41 is latch 24. It is fitted into the coupling groove (24a) formed in the).

The accommodation space 44 formed in the main body 41 and the handle 43 to be described later are provided with power transmission means for converting the linear movement of the handle into the rotational movement, respectively, in the accommodation space 44 formed in the main body 41. The component to be installed is not separated by the cover 48. In one embodiment of the present invention, the accommodation space 44 formed in the main body 41 by the power transmission means includes the first accommodation space 44a and the first accommodation space 44a. The pinion 49 is accommodated in the first accommodation space by dividing into two accommodation spaces 44b, and the first bevel gear 50 is accommodated in the second accommodation space, but these are integrated on the same shaft 51. At the same time, the cover 48 having the space portion 48a formed thereon is fixed to the main body 41 with a screw 52 so that the pinion 49 is exposed to the outside through the space portion, and the space portion is formed on the rear surface of the handle 43. To form a rack 53 engaged with the pinion 49 exposed to the outside through Was configured.

However, it will be understood that the power transmission means may be modified and applied in various forms by those skilled in the art in addition to the configuration illustrated as an embodiment of the present invention.

It is coupled to the main body 41 so as to be slidable left and right, the upper and lower portions of the rear of the handle 43 for rotating the rotating body 46 when the sliding door 31 is opened, respectively, are fitted in the guide holes of the main body 41. Guide protrusions 54a and 54b to be coupled to each other are formed. In the state where the handle 43 is horizontally coupled to the main body 41, the guide protrusions 54a and 54b are coupled to each other by the coupling means so that the handle is not separated from the main body 41. It is.

As the coupling means, the coupling groove 54c is formed in the guide protrusion 54a on one side, so that the two guide protrusions 54a and 54b are fitted into the guide holes 42a and 42b. The guide hole 54b on the other side of the guide hole 42a, which is fitted to one surface of the guide hole 42a, is fixed to the separation preventing piece 55 with a screw 56.

Therefore, when engaging the handle 43 through the guide holes 42a and 42b formed in the main body 41, the guide protrusions 54a and 54b pass through the guide holes 42a and 42b, and then the handle 43 When the upper side is pushed up), the coupling groove 54c formed in the guide protrusion 54a on one side is fitted into one surface of the guide hole 42a as shown in FIGS. 5A and 6 so that the guide protrusion 54b is coupled to the other side of the guide protrusion 54b. When the release preventing piece 55 is fixed with the screw 56, the handle 43 may be horizontally moved without being separated from the main body 41.

When the external force is removed from the handle 43, which is compressed and pulled while the handle 43 is horizontally moved between the rear surface of the main body 41 and the guide protrusions 54a and 54b, the handle 43 is initialized. An elastic member 57, such as a coil spring, is installed to return it to the fixing hole 58 formed at one side of the main body 41. The rubber spacer 59 is fitted to fix the handle on the surface of the spacer 59. It is comprised so that the back surface of 43 may be connected.

The reason why the rubber spacer 59 is fixed to the main body 41 is to allow the handle 43 to smoothly move horizontally while maintaining a constant distance to the main body 41.

On the other hand, a stopper protrusion 60 is formed in the second accommodation space 44b, and a cutout 47a is formed in the second bevel gear 47 installed in the second accommodation space, so that the sliding door 31 is formed. As the handle 43 is horizontally moved to release the locked state, the first and second cut surfaces 47b and 47c of the second bevel gear 47 formed by the cutout 47a are formed on the stopper protrusion 60. It is configured to be connected selectively.

When the knob 43 is horizontally moved to release the locked state of the sliding door 31, the rotor 46 is always rotated by 90 ° by the stopper protrusion 60, and then the external force is removed from the knob. This is for the portion 46a to be restored to the initial state in a horizontal state as shown by the solid line in FIG. 6.

Referring to the operation of the present invention configured as described above is as follows.

First, in the state in which the sliding door 31 is closed as shown in FIG. 2B, the pusher 17 is pressed by the striker 21 fixed to the door holder 37, so that the operating piece 19 is restored by the second elastic member 20. Positioned at the top dead center is caught by the striker 21, the latch 24 is maintained in a rotated state.

In addition, the handle 43 maintains the state as shown in FIG. 5A by the restoring force of the elastic member 57 provided between the main body 41 and the guide protrusions 54a and 54b.

The handle 43 is pushed in the direction of the arrow of FIG. 5A in the opening direction of the sliding door 31 to release the locking state of the sliding door 31, which is locked in this state, and at the same time, to open the sliding door 31. The guide protrusions 54a and 54b formed at 43 are moved in the horizontal direction by compressing the elastic member 57. At this time, the rear surface of the handle 43 is formed with a rack 53 and the rack The pinion 49 exposed to the outside through the space portion 48a formed in the cover 48 is installed in the first accommodating space 44a, and the horizontal linear motion of the handle 43 is converted into a rotational motion. Since the pinion 49 is rotated.

As shown in FIG. 5B, when the pinion 49 rotates in the direction of the arrow as shown in FIG. 5B, the first bevel gear 50 formed in the same shaft 51 as the pinion 49 is installed in the second accommodation space 44b. As shown in FIG. 6, the second bevel gear 47 engaged with the first bevel gear rotates in the direction indicated by the arrow of FIG. 6.

When the rotating body 46 rotates in the direction of the arrow, the engaging portion 46a integrally formed with the rotating body is fitted into the engaging groove 24a formed in the latch 24 so that the latch 24 rotates and the operating piece 19 ) Is lowered to the bottom dead center. At this time, the first cutting surface 47b of the second bevel gear 47 is connected to the stopper protrusion 60 formed in the second accommodation space 44b so that the rotor 46 is further connected. Since the coupling part 46b is maintained vertically without being rotated, the locked state of the sliding door 31 is released, and accordingly, the sliding door is opened by the operation of pushing the handle 43 in the opening direction of the sliding door 31. Is opened.

After opening the sliding door 31 in the operation as described above, the pusher 17 exits with the restoring force of the first elastic member 18 in the same way as the conventional locking device according to the release of the locked state and is located at the bottom dead center. The rise of the piece 19 is suppressed.

Therefore, when the external force is removed from the handle 43 in the state that the opening of the sliding door is completed, the handle 43 may be removed by the restoring force of the elastic member 57 compressed between the main body 41 and the guide protrusions 54a and 54b. The initial state is restored to 5a.

At this time, a stopper protrusion 60 is formed in the second accommodation space 44b, and a second cutting surface 47c is formed in the second bevel gear 47 so that the second cutting surface 47c abuts on the stopper protrusion. Since the rotating body 46 is no longer rotated, the handle 43 stops moving at the initial position and at the same time, the coupling part 46a maintains the horizontal state.

As described above, the present invention merely pushes the handle in the horizontal direction of the sliding direction of the sliding door to open the sliding door in the locked state, so that the linear movement is converted into the rotational movement by the power transmission means so that the latch rotates. As a result, housewives with weak wrist strength, as well as elderly or children, can easily open the living room sliding door of the weight.

In addition, even if repeated use, the power is transmitted by the engagement of the gear is configured to rotate the latch can be expected to effect that can significantly reduce the phenomenon that wear occurs in their assembly portion.
