DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lock holder for an electric lock which is used for an apartment, for example, and is most suitable for an earthquake-resistant door.

[0002]

2. Description of the Related Art In recent years, a predetermined clearance (about 13 mm) is provided between a door and a door frame in order to open the door when an earthquake occurs and to enable evacuation outside the room. In this way, even if the wall around the door frame is destroyed due to the earthquake and the door frame is deformed in the in-plane direction, the door can be opened with a predetermined gap between the door frame and the door Becomes

As shown in FIG. 6, the lock used for the above-described earthquake-resistant door is provided with a lock receiver 4 provided with a locking hole 40 in the door frame 1 and a locking hole in the door 2 side. The lock body 3 provided with the detachable kanuki 30 is attached to 40. In addition, when an earthquake occurs, the door frame 1 is deformed in the in-plane direction, causing a vertical displacement between the door frame 1 and the door 2.
A predetermined gap C1 is ensured between the upper and lower edges of the cantilever 30 and the upper and lower end surfaces thereof. In this way, even if a vertical displacement occurs between the door frame 1 and the door 2 during the occurrence of an earthquake, the kanuki 30 moves in the direction of displacement with respect to the locking hole 40 within the gap C1. Can be easily detached from the locking hole 40 without the burrowing of the burrow and the burrow 30 being deformed, and the door 2 can be opened.

[0004] Even in the above-mentioned earthquake-resistant doors, it is desirable to employ an electric lock which can be locked and unlocked by remote control, is easy to use, and has excellent security. In this electric lock, a magnet switch 31 is incorporated in the lock main body 3 and a magnet 41 is incorporated in the lock receiver 4 side, as indicated by a virtual line in FIG. Then, the opening / closing state of the door 2 is confirmed by the approach / separation of the magnet switch 41 to / from the magnet 31, and when the magnet switch 41 approaches the magnet 31, the kanuki 30 is put in and out of the locking hole 40 by remote control to unlock. Do the lock.

[0005]

However, when the magnet 41 is provided on the lock receiver 4 side as in the above-mentioned electric lock, the gap C1 secured for earthquake resistance becomes small. In other words, by providing the magnet 41, only a small gap C2 can be secured between the magnet 41 and the canker 30. For this reason, when a vertical displacement occurs between the door frame 1 and the door 2 at the time of the earthquake, it is not possible to cope with the small gap C2, and the kanuki 30 is moved by the magnet 41.
May collide and cause destruction of Kannuuki. If the kanuki is destroyed, the door 2 cannot be opened and it is difficult to evacuate to the outside. From the above, electric locks could not be used for seismic doors at present.
In particular, in the case of an earthquake-resistant door, a relatively large clearance is secured between the door frame 1 and the door 2 to compensate for the secure opening of the door 2, and the vertical displacement in the range of the clearance becomes large. 30 is easily destroyed. In order to cope with the vertical displacement, it is conceivable to secure a sufficiently large gap between the magnet 41 and the knuckle 30 by changing the vertical mounting position of the magnet 41 with respect to the lock receiver 4. However, in this case, the position of the magnet 41 with respect to the magnet switch 31 incorporated in the lock main body 3 changes, and the operation of the electric lock becomes impossible.

SUMMARY OF THE INVENTION An object of the present invention is to compensate for opening of a door and ensure evacuation to the outside without causing a destruction due to a shift between a door frame and a door when an earthquake occurs. It is an object of the present invention to provide a door lock receiving device provided with an electric lock which can be mounted on an earthquake-resistant door.

[0007]

According to a first aspect of the present invention, there is provided a door lock receiving device provided with an electric lock, wherein a door frame is deformed in a plane to cause a displacement between the door frame and the door. When this occurs, the magnet is movably supported by the lock receiver in this deviation direction.

[0008] According to the door lock receiving device provided with the electric lock described above, when a displacement occurs between the door frame and the door due to the occurrence of an earthquake, and when the kanuki moves in the direction of the displacement, the magnet is inserted through the kanuki. Moves in the shifting direction, that is, the moving direction of the kanuki. For this reason, the destruction of the cannus due to the collision of the cannus with the magnet is prevented beforehand. For this reason, even if it is assembled to an earthquake-resistant door, the opening of the door in the event of an earthquake is compensated, and it is possible to evacuate to the outside of the room. Therefore, locking and unlocking can be performed by remote control, so that the electric lock, which is easy to use and has excellent security, can be attached to the earthquake-resistant door.

Further , in the present invention, the magnet is supported by the holding member provided with the elongated hole extending in the direction in which the door frame and the door are shifted, and the holding member is movably supported by the lock receiver via the elongated hole. I have. According to this configuration, when a gap occurs between the door frame and the door and the kanuki moves in the direction of the shift, the holding member, that is, the magnet can be reliably moved along the long hole in the same direction as the movement. . Therefore, the intended purpose is realized with a simple configuration.

[0010] In the present invention, the holding member has a space for inserting and removing the cantilever, and has a mounting portion formed with a long hole, and a magnet support portion and a mounting portion provided on one side of the mounting portion. And a trigger sliding portion provided on the side. According to this configuration, when a gap occurs between the door frame and the door and the kanuki moves in the direction of the displacement, the kanuki contacts one side of the mounting portion to move the magnet, and at the same time, the trigger sliding contact occurs. Since the part is also moved, it is possible to prevent the trigger from entering the mounting part, thereby more reliably preventing breakage of the electric lock.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 5 shows, for example, an anti-seismic door portion used for an apartment or the like, which has a door frame 1 and a door 2 provided with a knob 20 which is openably and closably attached thereto.
A door lock receiving device provided with an electric lock L is mounted between the door frame 1 and the door 2. The lock receiving device for a door is mounted on the door 2 side, and includes a lock body 3 having a knuckle 30 and a magnet switch 31 which are also used as a notch and a deadbolt.

More specifically, the door frame 1 is formed integrally with a mounting portion 11 for mounting on a wall portion of an apartment or the like and continuously on an inner surface thereof, and forms a fitting portion of the door 2 when the door is closed. And the cylindrical portion 12
The mounting hole 10 extending in the up-down direction is formed on the inner side surface. A receiving portion 13 for receiving a later-described cover piece of the cover 7 is provided on the front side of the door frame 1 in the mounting hole 10.
To form In the embodiment shown in the drawings, notch grooves 14, 14 that are continuous with the mounting hole 10 are provided at the upper and lower portions of the mounting hole 10 on the front side of the door frame 1 in the cylindrical portion 12, and the notch groove 14 and the mounting hole 10 The receiving portion 13 is formed.

A fixing member 5 constituting the lock receiver 3
As is apparent from FIG. 2, a rectangular box-shaped main body 50 having a vertically elongated one side is opened, and mounting pieces 51, 51 integrally formed at upper and lower portions at an opening-side end of the main body 50. And Then, the main body 50 is moved from the mounting hole 10 to the cylindrical portion 1.
2, and each mounting piece 51 is formed in the upper and lower portions of the mounting hole 10 from the insertion hole 52 provided in each mounting piece 51 in a state where the mounting pieces 51 are in contact with the upper and lower portions of the mounting hole 10 in the cylindrical portion 12. By screwing a fixing screw 53 into the screw hole 15 thus formed, the main body 50 is fixed with the main body 50 interposed in the cylindrical portion 12 (FIGS. 3 and 4). In each of the drawings, a middle part of the main body 50 is cut away, and a cylindrical member 6 of a holding member 8 described later is cut.
It is possible to assemble inside. On the opposite sides of the mounting piece 51 at the upper and lower ends of the main body 50, outwardly projecting protrusions 50a, 50a are formed, and the upper and lower ends of the cylindrical member 6 are locked to these protrusions 50a. Thus, the position of the cylindrical member 6 is regulated with respect to the fixing member 5.

The cylindrical member 6 comprises a rectangular cylindrical main body 61 which can be inserted into the fixing member 5 and is supported by the main body 61 being fitted into the mounting hole 10 via the fixing member 5. . When the main body 61 is fitted into the mounting hole 10, the locking hole 40 for engaging and disengaging the kanuki 30 is formed in the side wall 62 of the main body 61 located on the outer surface side of the mounting hole 10. Screw holes 63, 63 for fixing the cover 7 are provided in the upper and lower portions. The locking hole 40 is
It is formed to be long in the up and down direction, and when an up and down shift S (FIG. 5) occurs between the door frame 1 and the door 2 due to the occurrence of the earthquake, the kanuki 30 does not bite into the locking hole 40. By moving the cannus 30 in the vertical direction, the cannus 30 are disengaged from the locking holes 40 so that the door 2 can be opened. Further, the side wall 6
A protrusion 64 protruding outward is provided integrally with the edge of the second body 2, and when the main body 61 is fitted into the mounting hole 10, the protrusion 64 is locked to the edge of the mounting hole 10. The side wall 62 where the 40 is formed is held flush with the mounting hole 10.

Further, when the door 2 is closed with respect to the door frame 1, the cylindrical member 6 is fixed at a predetermined interval T in a direction X in which an in-plane external force applied in the left-right direction of the door 2 is generated.
And is slidable in the X direction within the range of the interval T. On the other hand, when an out-of-plane external force Y in the front-rear direction perpendicular to the in-plane external force X is generated, the slide member cannot slide with respect to the fixing member 5. Thus, the tubular member 6 is supported so as to be fitted into the mounting hole 10 of the door frame 1 so as to oppose the out-of-plane external force Y.

The cover 7 has an insertion hole 70 facing the locking hole 40 formed in the cylindrical member 6, and a vertically long main body wall 71 fixed to the cylindrical member 6, and upper and lower sides thereof. When the in-plane or external force X of a predetermined value or more is generated, the cylindrical member 6 is deformed and slid with respect to the fixed member 5, and normally comes into contact with the inner surface of the cylindrical portion 12 of the door frame 1. Supporting pieces 72, 72 for supporting the cylindrical member 6 in a non-slidable manner on the fixing member 5 are integrally formed on one side in the width direction of the main body wall portion 71 on the front side of the door frame 1, and the mounting hole 10 and the fixing member 5 are formed. And a cover piece 73 that covers the entire tubular member 6 invisibly from the front side. The support pieces 72 and the cover pieces 73 are formed independently of each other.

In attaching the magnet 41 to the lock receiver 4, the following is performed. That is, as shown in FIG. 5, the door frame 1 is deformed in the in-plane direction (up-down direction) with the generation of the in-plane external force X in the up-down direction, and the lock receiver 3 on the door frame 1 side and the lock body 4 on the door 2 side are formed. When a shift S occurs between the magnet 41 and the lock receiver 4, the magnet 41 is movably supported in the direction of the shift S.

Specifically, a holding member 8 for supporting the magnet 41 is used, and the magnet 4 is
1 is movably supported in the direction in which the shift S occurs. The holding member 8 is bent in a substantially U shape in a side view, and
And a mounting portion 82 having a long hole 81 for vertically supporting the whole of the tubular member 6 and a supporting portion 83 of the magnet 41 provided on the upper side thereof. And a trigger sliding contact portion 86 provided on the lower side.

More specifically, the mounting portion 82 is formed as shown in FIG.
As can be seen from the above, a vertically extending mounting piece 82a to be mounted on the inner wall at the back of the main body 61 of the cylindrical member 6, and a pair of first and second first and second upper and lower members formed upright from both upper and lower edges.
It consists of standing pieces 82b and 82c.
The space 80 is formed in the interior surrounded by 2b and 82c, and the mounting piece 82a is formed with a long hole 81 extending in the vertical direction. Then, the fixing screw 8 is inserted through the elongated hole 81.
4 is a screw hole 65 provided on the inner wall at the back of the main body 61 of the cylindrical member 6
, So that the cylindrical member 6 supports the entire holding member 8 so as to be slidable in the vertical direction.

The support portion 83 is provided with a first standing piece 82.
a first protruding piece 83a protruding upward from the leading edge of the first protruding piece 82b, and a second protruding piece 83b extending from the upper edge of the first protruding piece 83b in parallel with the first upstanding piece 82b.
The magnet 41 is held between the second protrusions 83a and 83b in a sandwiching manner. The holding member 8 shown in the figure has a trigger sliding contact portion 86 for slidingly contacting the trigger of the electric lock with the same configuration as the support portion 83 below the mounting portion 82.

When assembling the lock receiver 3 to the door frame 1, first, as shown in FIGS. 3 and 4, the cylindrical member 6 is provided on the fixing member 5 at a predetermined interval T in the direction X in which in-plane and out-of-plane force is generated. By attaching each mounting piece 41 of the fixing member 5 to the door frame 1 with a fixing screw 43, the cylindrical member 6 is held in the mounting hole 10 via the fixing member 5. Next, in a state where the magnet 41 is held by the support portion 83 of the holding member 8, the entire holding member 8 is inserted inward from the locking hole 40 provided in the cylindrical member 6 to attach the holding member 8. Part 8
A fixing screw 84 is inserted through the long hole 81 formed in
The holding member 8 holding the magnet 41 in the tubular member 6 is slidably supported in the up-down direction by screwing into the screw hole 65 provided in the inner wall at the back.

Further, fixing screws 75, 75 are screwed into upper and lower screw holes 63 of the cylindrical member 6 from upper and lower insertion holes 74, 74 provided in the main body wall 71 of the cover 7. At this time, the cover 7
Are brought into contact with the inner side surface of the cylindrical portion 12 of the door frame 1, and when the in-plane and external forces X of a predetermined value or more are not applied by the support pieces 72, the cylindrical member 6 Is held non-slidable. The cover 73 provided on the cover 7 is inserted into the receiving portion 13 provided on the front side of the door frame 1 in the mounting hole 10. Then, the whole of the mounting hole 10, the fixing member 5, and the cylindrical member 6 are covered with the cover piece 73 invisible from the front side, so that the appearance is improved.

When the door 2 is used, the opening / closing state of the door 2 is checked by moving the magnet switch 31 toward and away from the magnet 41. When the magnet switch 31 is close to the magnet 41, the trigger 33 is activated. Moves over the trigger sliding contact portion 86, and automatically locks and unlocks by inserting and removing the cannus 30 into and out of the locking holes 40 by remote control from inside the room. In addition, Kannuki 30
Is operated by inserting a key into a keyhole (not shown) provided in the door 2 and operating the lock.

At this time, when an out-of-plane force in the Y direction is applied to the door frame 1 or the door 2, the cylindrical member 6 is fitted into the mounting hole 10 of the door frame 1 in a state where the cylindrical member 6 cannot slide with respect to the fixed member 5. Since it is held in the state and opposes the out-of-plane force Y,
Even when the lock 4 is used for an anti-seismic door having a predetermined clearance between the door frame 1 and the door 2, the strength against the out-of-plane force Y of the lock receiver 4 is increased to improve the security and wind pressure resistance.

When the door frame 1 is deformed by the earthquake and an in-plane or more external force X is generated, the cover 7 is pressed between the door frame 1 and the door 2 so that the support piece 72 is deformed. Then, the cylindrical member 6 slides in the direction of the in-plane / out-of-plane force X with respect to the fixed member 5. Further, since the cover 7 retreats toward the door frame 1 due to the deformation of the support piece 72, the cover 7 does not bite into the door 2 side. Accordingly, a predetermined gap is secured between the door frame 1 and the door 2, and the cannula 30 locked in the locking hole 40 of the tubular member 6 can be detached, so that the door 2 can be reliably opened. Evacuation to the outside is possible.

At this time, since each support piece 72 and cover piece 73 of the cover 7 are formed independently of each other, the deformability of each support piece 72 when an in-plane external force X exceeding a predetermined level is generated is enhanced. The cylindrical member 6 due to the deformation of the support pieces 72
Of the fixing member 5 is surely performed.

Further, the cover piece 73 of the cover 7 is provided with the receiving portion 13 formed on the front side of the door frame 1 in the mounting hole 10.
As described above, the mounting hole 10
When the in-plane external force X is greater than a predetermined value, the covering member 7 interposed in the receiving portion 13 can securely cover the entirety of the fixing member 5 and the cylindrical member 6 invisibly from the front side.
3 can be moved in the direction in which the in-plane external force X is generated, so that the in-plane external force X can be concentrated on the support piece 72. For this reason,
The deformability of the support piece 72 is further enhanced, and the sliding of the tubular member 6 due to the deformation of the support piece 72 is performed more reliably.

Further, the in-plane and external forces X as described above are generated,
Accordingly, when the door frame 1 is deformed into a diamond shape and a vertical shift S occurs between the door frame 1 and the door 2, the kanuki 30 moves in the locking hole 40 in the direction of the shift, and the kanki 30 The whole of the holding member 8 holding the magnet 41 moves along the long hole 81 in the shift direction.
For this reason, the destruction of the cannus 30 due to the collision of the cannus 30 with the magnet 41 is prevented beforehand. Therefore, the opening of the door 2 at the time of the occurrence of the earthquake is compensated, and the evacuation to the outside can be reliably performed.

Further, at this time, the cannus 30 move within the space 80 of the mounting portion 82 provided on the holding member 8, while the magnet 41 supports the upper side of the mounting portion 82 separated by the first upright piece 82b. When the cannus 30 move due to the displacement, the cannula 30 comes in contact with the first upright piece 82b of the mounting portion 82 to move the magnet 41, and at the same time, the trigger sliding contact portion The trigger can be prevented from entering the mounting portion, thereby breaking the kanuki and causing the electric lock L to move.
Is more reliably prevented.

The above electric lock L is not limited to an earthquake-resistant door.
It can also be used for normal doors.

[0032]

As described above, according to the door lock receiving device provided with the electric lock of the present invention, even if the door frame is displaced due to the deformation of the door frame at the time of an earthquake, Without causing the destruction of Kannuki by this shift, it is possible to compensate for the opening of the door and to evacuate to the outdoor reliably,
It becomes possible to assemble it to an earthquake-resistant door.
