Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art In general, in an apartment or the like, a lock receiver is attached to a door frame, and locking and unlocking is performed by engaging and disengaging a lock body provided on a door side of the lock receiver. At this time, it is necessary for the lock receiver to secure a high strength against an out-of-plane external force applied in a direction orthogonal to the door when the door is closed, in order to enhance security and wind resistance.

In recent years, a predetermined clearance (about 13 mm) has been provided between the door and the door frame in order to open the door surely in the event of an earthquake and enable evacuation outside the room. Also in this case, the lock receiver needs to maintain high strength against an out-of-plane external force. In addition, when an earthquake occurs, the walls around the door frame are destroyed, and the door frame is deformed to generate an in-plane external force in the horizontal direction orthogonal to the out-of-plane external force. Then, it is necessary to be able to deform between the door frame and the door in the direction in which the in-plane and external forces are generated. As described above, when the in-plane or out-of-plane force exceeding a predetermined value is generated, by deforming the lock receiver in the direction in which the force is generated, a predetermined gap can be secured between the door frame and the door, and the lock is locked in the lock hole of the lock receiver. It is also possible to remove the cannus on the door side, so that the opening of the door is compensated and evacuation to the outside can be performed reliably.

[0004] From the above, conventionally, for example, a door lock receiver 80 as shown in FIG. 8 is used. This lock receiver 80
Is a main body wall portion 82 formed with a locking hole 81 of kanuki,
Connecting pieces 83, 83 provided integrally on the upper and lower sides thereof, and fixing pieces 84, 84 formed in a step shape parallel to the main body wall portion 82 via the connecting pieces 83 and fixed to the inner surface of the door frame 90.
These are formed by pressing a steel plate. Then, each fixing piece 84 is fixed to the inner surface of the door frame 90 with a fixing screw or the like, and locking or unlocking is performed by engaging and disengaging the door-side cannula with the locking hole 81 of the main body wall portion 82.

[0005]

However, in the case of using the lock receiver 80 described above, when the door frame 90 is deformed and an in-plane external force is generated in the X direction, each of the connecting pieces 83 and the main body wall are moved in the same direction. Since the portion 81 is deformed, the door can be opened, but the following inconsistent problems occur. That is,
In order to enhance the deformability of the lock receiver 80 with respect to the in-plane and external forces X and compensate for the reliable opening of the door, it is desirable to reduce the thickness of the steel plate forming the lock receiver 80. The strength against the out-of-plane force in the Y direction applied to the receiver 80 is weakened, which is not preferable in terms of security, wind pressure resistance, and the like. In addition, it is conceivable to increase the deformability by reducing the width of the lock receiver, but in this case, not only does the strength of the lock receiver become weaker, but when the lock receiver is deformed by an in-plane external force, a part of the lock receiver is deformed. It cuts into the door side and the door cannot be opened.

On the other hand, in order to enhance the strength against the out-of-plane force Y to enhance security, the thickness of the steel plate may be increased, but in this case, the deformability of the lock receiver 80 is impaired,
Opening doors during an earthquake is likely to be uncertain. As described above, with the conventional lock receiver 80, it is difficult to simultaneously enhance security and wind pressure resistance and to ensure that the door is opened when an earthquake occurs. Moreover, when each fixing piece 84 of the lock receiver 80 is attached to the inner surface of the door frame 90, a space is formed between the inner surface and the main body wall portion 82, giving the user a soft feeling. The appearance also worsens.

SUMMARY OF THE INVENTION An object of the present invention is to provide a lock for doors which can improve security and wind resistance, compensate for reliable opening of the door when an earthquake occurs, and enhance the appearance. is there.

[0008]

According to a first aspect of the present invention, there is provided a door lock retainer for fixing to a mounting hole provided in a door frame, and a door member for engaging and disengaging a knuckle on a door side. A stopper hole is formed, the tubular member is inserted into the fixing member, and is supported in a state of being fitted into the mounting hole via the fixing member. The tubular member is fixed to the tubular member, and the mounting hole, the fixing member, and the tubular member are fixed. A cover that covers the entirety, and the tubular member is inserted into the fixing member at a predetermined interval in a direction of generation of an in-plane external force applied in a direction parallel to the door when the door is closed, and the in-plane outside When it is slidable in the direction of force generation, and when an out-of-plane force in the direction orthogonal to the in-plane force is generated, the slide member is not allowed to slide with respect to the fixing member, and is held in a state fitted in the mounting hole of the door frame. I am trying to counter the out-of-plane external force, and the cover is Deformation occurs when a predetermined or more in-plane and external force is generated, and allows the cylindrical member to slide on the fixing member in the direction in which the force is generated, and is normally held by the door frame so as to prevent the cylindrical member from sliding on the fixing member. ing.

According to the lock receiving device described above, the cover does not allow the cylindrical member to slide in the normal state when no more than a predetermined in-plane or external force is applied, and the cylindrical member is fixed to the mounting hole of the door frame through the fixing member. By holding the door side in the locking hole provided in the tubular member,
The door is locked and unlocked. When the door frame is deformed due to the earthquake and an in-plane or more external force is generated,
The cover sandwiched between the door frame and the door is deformed, and the tubular member slides relative to the fixed member in a direction in which in-plane and out-of-plane forces are generated.
Further, the cover retreats to the door frame side due to the deformation, so that the cover does not bite into the door side. Therefore, a predetermined gap is secured between the door frame and the door, and since the cannus locked in the locking holes of the cylindrical member can be detached,
The door can be reliably opened, and evacuation to the outside of the room is possible. On the other hand, when an out-of-plane force is applied to the door frame or door,
The cylindrical member is held in a state of being fitted into the mounting hole of the door frame in a state where it cannot slide with respect to the fixing member, so as to oppose the out-of-plane force. As a result, security and wind pressure resistance are improved.

In a preferred embodiment of the present invention, the cover has an insertion hole opposed to the locking hole of the cylindrical member, and is integrally formed on both sides in the longitudinal direction with a main body wall fixed to the cylindrical member. A support piece that deforms when the above-mentioned in-plane and external forces are generated, slides the cylindrical member with respect to the fixed member, and normally abuts against the door frame to support the cylindrical member so that the cylindrical member cannot slide on the fixed member; The cover is formed integrally with the front side of the door frame on one side in the width direction of the portion, and covers the mounting hole and the entirety of the fixing member and the tubular member invisibly from the front side. According to this configuration, the support member provided on the cover makes it impossible to slide the tubular member with respect to the fixed member at normal times, and reliably slides the tubular member with respect to the fixed member when a predetermined or more in-plane external force is generated. Let me do. Therefore, the intended purpose is realized with a simple configuration. In addition, by covering the whole of the mounting hole, the fixing member, and the cylindrical member with the cover piece invisibly from the front side, the appearance is improved.

In a preferred embodiment, the support piece of the cover is formed independently of the cover piece. According to this configuration, the deformability of the support piece when a predetermined or more in-plane and external force is generated can be enhanced, and the cylindrical member can be reliably slid with respect to the fixing member due to the deformation of the support piece.

Further, in a preferred embodiment, a receiving portion for receiving the cover piece of the cover is formed around the mounting hole of the door frame. According to this configuration, by interposing the cover piece in the receiving portion, the entirety of the mounting hole, the fixing member, and the cylindrical member can be securely covered invisible from the front side, so that the appearance can be further enhanced. Moreover, when an in-plane or out-of-plane force exceeding a predetermined level is generated, the covering piece interposed in the receiving portion can be moved in the direction of the in-plane or out-of-plane force, so that the in-plane and out-of-plane force is concentrated on the support piece to enhance its deformability. Moreover, the sliding of the cylindrical member due to the deformation of the support piece can be performed more reliably.

The side wall 62 in which the locking hole 40 is formed is held flush with the mounting hole 10.

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 is applied in the left-right direction in parallel with the door 2. It is inserted into the member 5 and slidable in the X direction within the range of the interval T. On the other hand, the in-plane external force X and the out-of-plane external force Y in the direction orthogonal to the plane
Occurs, the cylindrical member 6 is supported against the out-of-plane external force Y by being 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 fixing member 5.

The cover 7 is provided with a locking hole 40 of the cylindrical member 6.
And a vertically elongated main body wall 71 fixed to the cylindrical member 6 and integrally formed on both upper and lower sides thereof, and are deformed when a predetermined or more in-plane external force X is generated. The cylindrical member 6 is slid with respect to the fixing member 5, and normally, the support pieces 72, 72 which abut against the inner surface of the cylindrical portion 12 of the door frame 1 and support the cylindrical member 6 to the fixing member 5 so as not to slide.

It has. The support pieces 72 and the cover pieces 73 are formed independently of each other.

When assembling the lock receiver 4 to the door frame 1, as shown in FIGS.
At predetermined intervals T in the direction X in which the in-plane and external forces are generated,
By attaching each mounting piece 51 of the fixing member 5 to the door frame 1 with the fixing screw 53, the cylindrical member 6 is held in the mounting hole 10 via the fixing member 5.

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 surface of the cylindrical portion 12 of the door frame 1, and when the in-plane external force X of a predetermined value or more is not applied by the support pieces 72, the cylindrical member 6 Is held non-slidable.

Then, the notches 31 and the notches 31 provided on the lock body 3 on the door side are engaged and disengaged from the insertion holes 70 of the cover 7 to the locking holes 40 provided on the cylindrical member 6, respectively.
The door 2 is kept closed, locked or unlocked. The cover 73 provided on the cover 7 is inserted into the receiving portion 13 formed 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 by the cover piece 73 invisible from the front side, so that the appearance is improved.

At this time, when an out-of-plane force in the Y direction is generated in 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 a state and opposes the out-of-plane external force Y,
Even when the lock 4 is used for seismic resistance with a predetermined clearance formed between the door frame 1 and the door 2, the strength against the out-of-plane external force Y of the lock receiver 4 is increased, so that the security and wind pressure resistance are improved.

On the other hand, when the door frame 1 is deformed due to 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 to deform the support piece 72. 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. Therefore, door frame 1
A predetermined clearance is secured between the door member 2 and the cylindrical member 6.
It is also possible to release the cannula 30 locked in the locking hole 40 provided in the door 2, so that the door 2 can be reliably opened and evacuation to the outside can be performed. Further, in the embodiment shown in the drawings, the surface facing the door 2 is formed flat by the body wall 71 of the cover 7 so that a part of the body wall 71 faces the door 2 when an in-plane external force X is generated. It makes it possible to more reliably prevent digging.

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 a 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.

In FIG. 5, the vertical axis represents the in-plane external force (N), and the abscissa represents the slide amount (mm) of the lock receiver relative to the in-plane external force. As is clear from the figure, in the lock receiver of the present invention, the sliding amount with respect to the in-plane and external forces is larger than the conventional one. Therefore, when an earthquake occurs, a predetermined gap is secured between the door frame and the door, and the door is reliably opened.

FIG. 6 shows the out-of-plane force (N) on the vertical axis.
The horizontal axis indicates the amount of deformation of the lock receiver with respect to the out-of-plane force with the amount of deformation (mm) taken. As is clear from the figure, the lock receiver of the present invention has almost no change in the deformation of the lock receiver with respect to the out-of-plane external force as compared with the related art. For this reason, high strength against out-of-plane external force is secured, and security and wind pressure resistance are improved.

The lock receiver described above can be used not only for an earthquake-resistant door but also for a normal door.
