Further, when the locking device 106 is operated in a state where the sliding door main body 104 is abutted against the vertical frame 102, the sliding door main body 104 is connected to the vertical frame 103 and locked by the locking device 106.

JP-A-8-254053

  By the way, in the general sliding door mentioned above, the frame 103 is also distorted whenever a building shakes by an earthquake or the like. Specifically, as shown in FIG. 16 and FIG. 17, the vertical frame 101 that should have been erected vertically is tilted by shaking such as an earthquake, and the sliding door main body 104 and the vertical frame 101 are in contact with each other. Changes.

  At this time, if the sliding door main body 104 and the vertical frame 101 are connected by locking, the locking device 106 and the vertical frame are based on the principle of the lever using the upper part (FIG. 16) and the lower part (FIG. 17) of the door tip as fulcrums. An excessive load is applied to 101, and depending on the degree of shaking, the locking device 106 may be damaged or the vertical frame 101 may be deformed.

  In recent years, two-lock type sliding doors having locking devices at two places in the vertical direction have also become widespread. In this 2 lock type sliding door, the vertical frame and the sliding door main body are firmly connected as compared to the 1 lock type sliding door. Therefore, stress is easily concentrated on the vertical frame in the immediate vicinity of the locking device. Is likely to cause deformation. In addition, the deformation of the vertical frame may cause the shape of the entire frame to collapse, which may cause difficulty in opening and closing the sliding door.

  This invention is made | formed in view of said situation, and makes it a subject to provide the structure of the sliding door which has earthquake resistance, and the earthquake-resistant locking device for sliding doors.

In order to solve the above problems, the present invention
A sliding door seismic structure having a sliding door main body, a vertical frame standing on the door end side of the sliding door main body, and a locking device that connects and locks the sliding door main body to the vertical frame,
The locking device has a retractable locking body and a lock receiver connected to the locking body at the time of locking, and the connecting portion is provided to be displaceable in the sliding door opening / closing direction. To do.

  In this structure, the connection part of a locking body and a lock receptacle, ie, a locking part, is provided displaceably in the sliding door opening / closing direction. For this reason, the said connection part can accept | permit rocking | fluctuation of a vertical frame. For example, even if the abutting state of a pillar or joinery frame (hereinafter referred to as a vertical frame) and the sliding door main body changes due to the shaking of the earthquake, the connecting part of the locking device is displaced in the sliding door opening / closing direction to follow the change. . Therefore, the concentration of stress on the locking device and the surrounding vertical frame is avoided by the displacement of the connecting portion.

In addition, the displacement of the connection part described in the present invention can be achieved not only by the relative displacement of the connection part in the locking device but also by the displacement accompanied by the movement of the entire locking device.
Further, the sliding door body in the present invention intends all doors that can be opened and closed left and right within a plane parallel to the vertical frame, such as an entrance sliding door, a sliding door, a window sash, a screen door, and a horizontal shutter. .

  The structure by which the displacement to the sliding door opening direction in the said connection part is restrict | limited may be sufficient.

  In such a configuration, since the displacement of the connecting portion is limited in the sliding door opening direction, the reliability as the locking device can be secured while obtaining the earthquake resistance. Here, the restriction may be any of prohibiting the displacement itself and suppressing the amount of displacement.

Between the sliding door main body and the vertical frame, a gap is secured in the sliding door fully closed state,
The locking device may be configured to project inward of the gap so as to compensate for this gap.

  In this configuration, a clearance is secured in advance between the sliding door main body and the door contact surface of the vertical frame, and unnecessary contact between the vertical frame and the sliding door main body due to shaking such as an earthquake is avoided by this clearance. Therefore, the action of the insulator using the upper and lower ends of the sliding door body as a fulcrum is suppressed.

  The structure provided in the vertical direction several place of the said sliding door main body and a vertical frame may be sufficient as the said locking device.

This structure is a structure corresponding to a so-called two-lock type sliding door. Since the vertical frame and the sliding door main body are firmly connected to the two-lock type sliding door as compared with the one-lock type sliding door, stress is likely to concentrate on the vertical frame in the immediate vicinity of the locking device. In this regard, in this configuration, since the connecting portion of the locking device is provided so as to be displaceable in the sliding door opening / closing direction, the stress is not concentrated on the vertical frame immediately adjacent to the locking device, and the stress is distributed throughout the vertical frame.
When used in combination with the above-described structure having a gap, each locking device provided at a plurality of locations in the vertical direction receives a force in a direction in which it is compressed or separated between the sliding door body and the vertical frame. In this regard, in this configuration, the force in the direction of compression or separation can be absorbed by the displacement in the sliding door opening / closing direction, so that the load applied to the locking device can be reduced.

  The lock body is provided on the sliding door body side, the lock receiver is provided on the vertical frame side, and the lock receiver is provided so as to be displaceable in the sliding door opening / closing direction with respect to the vertical frame. But you can.

  In this configuration, a lock receiver, which is a component of the locking device, is provided so as to be displaceable with respect to the vertical frame. For this reason, even if the vertical frame is tilted due to shaking, the lock holder can cope with the tilt of the vertical frame while maintaining the connection state with the lock body.

  The lock receiver may be constantly biased in any one of the sliding door opening and closing directions.

  In this configuration, the lock receiver is always urged in any one of the sliding door opening and closing directions, so that it can be selectively used according to the direction of the load applied to the locking device. That is, when the lock receiver is constantly urged in the sliding door opening direction, it can cope with the load on the compression side. On the contrary, when it is always urged in the sliding door closing direction, it can cope with the load in the pulling direction.

The present invention also discloses an earthquake-resistant locking device for sliding doors as means for solving the above problems.
That is, the present invention is an earthquake-resistant locking device for a sliding door comprising a sliding door main body and a vertical frame standing on the door end side of the sliding door main body,
It has a lockable body that can be moved in and out, and a lock receiver connected to the lockable body at the time of locking, and the connecting portion is provided so as to be displaceable in the sliding door opening and closing direction.

  The structure by which the displacement to the sliding door opening direction in the said connection part is restrict | limited may be sufficient.

  The lock receiver may be constantly biased in any one of the sliding door opening and closing directions.

A bracket for fixing the lock receiver to the vertical frame;
The lock receiver may be configured to be displaceable in the sliding door opening / closing direction via the bracket.

  Various configurations described in the means for solving the problem can be combined without departing from the problem of the invention.

<First Embodiment>
As shown in FIG. 3, the sliding door 1 shown in the present embodiment includes a frame 4 composed of a vertical frame 2 and an upper frame 3, and a sliding door that is suspended from the upper frame 3 and can be freely opened and closed in the frame 4. It comprises a main body 5 and a locking device 10 that locks the sliding door main body 5 by connecting it to the vertical frame 2 and has a basic structure of a so-called suspension type sliding door.

In addition, a gap C is secured in advance between the sliding door body 5 and the vertical frame 2 in a fully closed state in order to allow swinging such as an earthquake. And unnecessary interference with the vertical frame 2 is prevented. Further, the inner edge 2a of the vertical frame 2 protrudes toward the sliding door main body 5 in order to cover the gap C from the outside, and the door end side edge of the sliding door main body 5 is accommodated in the vertical frame 2 in the fully closed state.
Here, “swaying” and “swaying” include, of course, shaking in the event of an earthquake, but swinging or shaking other than earthquakes, for example, the vertical frame 2 due to consciousness or unconsciousness by machines or people, etc. The case where the vertical frame 2 or the sliding door main body 5 swings as a result of the contact with the sliding door main body 5, the opening operation of the sliding door main body 5, or the indirect vibration from the outside is also included. The swing of the vertical frame 2 and the swing of the sliding door main body 5 are relative to each other. In the present invention, the “swing of the vertical frame 2” refers to the swing of the vertical frame 2 only, the sliding door main body 5 only. And the swinging of both the vertical frame 2 and the sliding door main body 5.

The locking device 10 is provided at two locations on the top and bottom between the sliding door body 5 and the vertical frame 2. Further, as shown in FIG. 4, each locking device 10, 10 has a lock main body 20 in which a hook-shaped lock body 21 is incorporated, a lock receiver 30 connected to the lock body 21, and a lock receiver 30. And a bracket 40 for fixing to the frame 2.
In each locking device 10, 10, the lock main body 20 is provided on the sliding door main body 5 side, and the lock receiver 30 is provided on the vertical frame 2 side via the bracket 40.

  The lock body 20 is embedded in the door contact surface (side edge 5 a) of the sliding door body 5. The locking body 21 provided in the lock body 20 is incorporated so as to protrude toward the lock receiver 30 on the vertical frame 2 side like a hook by a locking operation such as Santam and a key cylinder.

The lock receiver 30 is a so-called strike provided with a lock opening 31 for retaining the lock body 21, and is manufactured by bending a metal plate into a substantially C-shaped cross section as shown in FIGS. A locking opening 31 is formed in the back portion 32. Moreover, the front-end | tip of the both-sides board parts 33 and 34 bent at right angle with respect to the back 32 is further turned toward the inner side of the lock receptacle 30 (code | symbols 33a and 34a in FIG. 2).
The engaging member 22 that contacts the back portion 32 of the lock receiver 30 and engages with the lock body 21 is fitted into a recess provided in the lock body 21, thereby making locking more reliable. The engaging member 22 is not essential. In short, it is sufficient that a predetermined locking effect is obtained by engaging the locking body 21 with the lock receiver 30, and the configuration itself is arbitrary.

  On the other hand, the bracket 40 is manufactured by bending a metal plate having a rectangular cross section which is longer than that of the lock receiver 30. Specifically, as shown in FIG. 2, both edge portions along the longitudinal direction of the metal plate are bent in the same direction, and the bent portions 41 and 42 are cut out from the outer edge into a trapezoidal shape.

Further, the width L1 of the notched portion (42a in FIG. 2) is substantially equal to the total length of the lock receiver 30, and the lock receiver 30 is folded back with the bracket 40 incorporated in the lock receiver 30 as shown in FIG. The portions 33a and 34a are loosely fitted into the notched portion 42a of the bracket 40.
In FIGS. 1 and 2, for the sake of illustration, the notch portion at the back of the drawing is not visible, but a trapezoidal notch portion is formed on the opposite side of the bracket 40 as in the front side of the drawing. Yes.

Further, the back portion 43 of the bracket 40 is also greatly cut out corresponding to the locking opening 31 on the side of the lock receiver 30, and leaf springs 44 and 45 are incorporated as elastic bodies therein as shown in FIG. It is.
The leaf springs 44 and 45 protrude from the back side of the bracket 40 to the front side. When the bracket 40 and the lock receiver 30 are combined, the plate springs 44 and 45 are always in a direction away from the bracket 40 as shown in FIG. Energized.

  As shown in FIGS. 1 and 5, the folded portions 33a and 34a of the lock receiver 30 are loosely fitted in the trapezoidal cutouts 41a and 42a formed on the both side surfaces 41 and 42 of the bracket 40 in the above state. The lock receiver 30 is always urged in a direction to be displaceable at the depth of the notches 41 a and 42 a and away from the bracket 40 without falling off the bracket 40. In other words, the folded portions 33 a and 34 a of the lock receiver 30 serve as stoppers, and the displacement of the lock receiver 30 is limited in the direction in which the lock receiver 30 is separated from the bracket 40.

  Since the notches 41a and 42a formed on both side surfaces 41 and 42 of the bracket 40 are notched in a trapezoidal shape, the lock receiver 30 is guided to the edges (trapezoidal leg portions) of the notches 41a and 42a. And centered.

  Screw holes 46 for fixing the bracket 40 to the vertical frame 2 are formed at both ends of the bracket 40, and the bracket 40 is screwed to the door contact surface 2b of the vertical frame 2 with the lock receiver 30 side. Has been.

  4 and 5, the surface of the bracket 40 is substantially flush with the door contact surface 2b in the attached state, and the lock receiver 30 normally protrudes from the door contact surface 2b toward the sliding door body 5 side. ing. In the present embodiment, the normal state refers to a state in which an external force other than the leaf spring is not acting on the lock receiver 30.

  As described above, in the locking device 10 shown in the present embodiment, the lock receiver 30 protrudes inward of the gap C so as to compensate for the gap between the sliding door body 5 and the vertical frame 2, and in the fully closed state of the sliding door, The surface of the receptacle 30 is in contact with the lock body 20 on the sliding door body 5 side. Therefore, even when the gap C is provided between the vertical frame 2 and the sliding door main body 5, the locking opening 31 and the locking body 21 of the lock receiver 30 can be connected to each other.

  In FIG. 4 where the locking opening 31 of the lock receiver 30 and the locking body 21 of the lock body 20 are connected to each other, the circled portion corresponds to the connecting portion in the present invention.

Then, the earthquake resistance effect of the sliding door 1 which has the above-mentioned clearance gap C and the locking device 10 is demonstrated.
As described in the background art, in this type of sliding door 1, the contact state between the sliding door 1 and the vertical frame 2 changes due to shaking such as an earthquake. Further, when the sliding door body 5 and the vertical frame 2 are locked, the locking device 10 and the vertical frame 2 are excessively large due to the principle of the lever with the upper part (FIG. 16) and the lower part (FIG. 17) of the door tip as fulcrums. A load is applied.

  On the other hand, the sliding door 1 shown in the present embodiment is provided with a gap C between the sliding door body 5 and the vertical frame 2 in advance. For this reason, even if the vertical frame 2 is tilted to the left or right due to an earthquake or the like, a clearance (C1 in FIG. 6) and (C2 in FIG. 7) are secured at the upper and lower ends of the sliding door body 5 as shown in FIGS. Is done. That is, a gap C is provided between the sliding door body 5 and the vertical frame 2 to allow shaking such as an earthquake, and unnecessary contact between the vertical frame 2 and the sliding door body 5 is avoided by the gap C. Therefore, the action of the lever with the upper and lower ends of the sliding door body 5 as a fulcrum is suppressed, and the degree of force applied to the locking devices 10 and 10 is reduced.

  In the present embodiment, since a two-lock type locking system having the locking devices 10 and 10 at two places in the vertical direction is adopted, each of the locking devices 10 and 10 has a sliding door body 5 and a vertical frame in accordance with shaking such as an earthquake. 2 receives a compressive force and a tensile force (see arrows A and B in FIGS. 6 and 7).

  In this respect, the sliding door 1 shown in the present embodiment is provided such that the lock receivers 30 of the locking devices 10 and 10 can be displaced with respect to the vertical frame 2 in the sliding door closing direction (direction of arrow A in FIG. 8). In other words, when receiving a force in the compression direction in the locked state, the lock receiver 30 is retracted into the vertical frame 5, and the connecting portion between the lock receiver 30 and the lock body 21 is also displaced toward the sliding door closing direction (see FIG. 9). Therefore, breakage of the locking device 10 due to compressive force and deformation of the vertical frame 2 around the locking device are avoided.

  Further, when the sliding door body 5 is opened in the locked state, the folded portions 33a and 34a of the lock receiver 30 are in contact with the inner edges of the notches 41a and 42a on the bracket 40 side. Movement is prevented. That is, the connecting portion between the lock receiver 30 and the locking body 21 is not displaced in the sliding door opening direction, and the function as the locking device 10 is thereby maintained.

  Next, the second embodiment of the present invention will be described.

<Second Embodiment>
In 1st Embodiment, the avoidance measure of the compressive force which acts on the locking device 10 was demonstrated.
In this regard, in the two-lock type locking method, while the compressive force is acting on one locking device 10, the tensile force is acting on the other locking device 10 (in FIG. 6 and FIG. 7, the arrow B). reference)

  For this reason, in the second embodiment, for example, a lock holder is provided so as to be accessible on the sliding door body side in order to cope with a pulling force at the time of an earthquake swing. That is, in the first embodiment, the lock holder 30 is provided so as to be displaceable in the sliding door closing direction (in the direction of arrow A in FIG. 8) with respect to the vertical frame 2, whereas in the second embodiment, The difference is that the lock holder is provided so as to be displaceable with respect to the vertical frame 2 in the sliding door opening direction (in the direction of arrow A in FIG. 12).

  The second embodiment is slightly different from the first embodiment in the structure of the lock receiver and bracket and the shape of the mounting portion thereof, and the structure of the lock body 20 and the upper frame 3 is the same as in the first embodiment. Same as 1. Therefore, hereinafter, the different lock receiver 50 and bracket 60 will be mainly described. Further, the same portions are described with the same reference numerals.

  The lock receiver 50 shown in the second embodiment is made of a metal plate bent in a substantially C-shaped cross section as shown in FIGS. 10 and 11, and a locking opening 51 is formed in the back portion 52. . Moreover, the front-end | tip of the both-sides board parts 53 and 54 bend | folded at right angle with respect to the back | dorsal 52 is further folded toward the inner side of the lock receptacle 50 (in FIG. 11, code | symbol 53a, 54a).

On the other hand, the bracket 60 is made of a rectangular metal plate that is longer than that of the lock receiver 50, and is manufactured by bending both side edges 60a excluding the vicinity of the end thereof to the back side as shown in FIGS.
10 and 11, the side edge at the back of the drawing is not visible for the sake of illustration, but the side edge on the opposite side of the bracket 60 is also bent in the same manner as the front side of the drawing.

  As shown in FIG. 11, the width L2 of the bent side edges 60a is substantially equal to the length of the lock receiver 50. With the bracket 60 incorporated in the lock receiver 50 as shown in FIG. Both side plate portions 53, 54 are loosely fitted to both side edges 60 a of the bracket 60.

  Further, the back portion 62 of the bracket 60 is also largely cut away corresponding to the locking opening 51 on the lock receiver 50 side, and the notch 62a prevents interference between the locking body 21 and the bracket 60 during locking. Yes.

Plate springs 63 and 64 are provided on the back surface of the bracket 60.
The leaf springs 63 and 64 project from the back surface side of the bracket 60 and abut against the folded portions 53a and 54a of the lock receiver 50 from the inside in a state where the bracket 60 and the lock receiver 50 are combined.
That is, the leaf springs 63 and 64 are always biased in the direction in which the back portion 52 of the lock receiver 50 is brought closer to the bracket 60 as shown in FIG.

  Screw holes 65 for fixing the bracket 60 to the vertical frame 2 are formed at both ends of the bracket 60, and the bracket 60 is screwed to the door contact surface 2b of the vertical frame 2 with the lock receiver 50 side. It has been stopped. The leaf springs 44 and 45 are fastened together between the vertical frame 2 and the bracket 60 by screws used when the bracket is fixed.

As shown in FIG. 12, the mounting portion of the bracket 60 on the door contact surface 2 b of the vertical frame 2 protrudes inward of the clearance C to compensate for the clearance between the sliding door body 5 and the vertical frame 2. Is fixed to the protruding portion 2c of the door contact surface 2b.
That is, the bracket 60 and the lock receiver 50 provided on the bracket 60 project inward of the gap C via the projecting portion 2c of the door contact surface 2b so as to compensate for the gap between the sliding door body 5 and the vertical frame 2. In the fully closed state of the sliding door, the surface of the lock receiver 50 is in contact with the lock body 20 on the sliding door body 5 side. Therefore, even in a state where there is a gap C between the vertical frame 2 and the sliding door main body 5, the locking opening 51 on the lock receiver 50 side and the locking body 21 on the lock main body 20 side can be connected.

  In addition, the site | part enclosed with a circle in FIG. 12 in which the locking opening part 51 by the side of the lock receptacle 50 and the locking body 21 of the lock main-body part 20 are connected corresponds to the connection site | part of this invention.

Next, the seismic effect achieved by the lock receiver 50 and the bracket 60 will be described.
As described above, in the two-lock type locking method, while a compressive force is applied to one locking device 10, a tensile force is applied to the other locking device 10 (see arrows B in FIGS. 6 and 7). )

  In this regard, the sliding door 1 shown in the second embodiment is provided with the lock receivers 50 of the locking devices 10 and 10 so that they can be displaced with respect to the vertical frame 2 in the sliding door opening direction (direction of arrow A in FIG. 12). That is, when receiving a force in the pulling direction in the locked state, the lock receiver 50 is pulled out from the vertical frame 5, and as a result, the connecting portion of the lock receiver 50 and the lock body 21 is also displaced in the sliding door opening direction side (see FIG. 11). . Therefore, breakage of the locking device 10 due to the pulling force and deformation of the vertical frame 2 around the locking device are avoided.

  Even when the sliding door body 5 is opened in the locked state, the folded portions 53a and 54a of the lock receiver 50 abut against the side edges (60a) and 60b of the bracket 60 as shown in FIG. The movement of the lock receiver 50 is restricted. That is, the connection part of the lock receiver 50 and the lock body 21 is not displaced more than necessary in the sliding door opening direction, and the function as the lock device 10 is thereby maintained.

  As described above, the seismic structure according to the sliding door 1 and the locking device 10 of the present invention provides the clearance C between the sliding door body 5 and the vertical frame 2 and allows the lock receptacles 30 and 50 to be freely displaced in the sliding door opening / closing direction during locking. Therefore, deformation and damage of the vertical frame 2 and the locking device 10 are avoided. Moreover, since the deformation | transformation and damage of the vertical frame 2 and the locking device 10 are avoided, the sliding door main body 5 can be opened and closed also at the time of a disaster, and also the recovery after a disaster is easy.

  In each of the above-described embodiments, the gap C is provided between the sliding door body 5 and the vertical frame 2 to suppress the action of the lever, but only the locking device 10 of the present invention that is displaceable in the sliding door opening / closing direction. However, the earthquake resistance of the sliding door 1 and the locking device 10 can be ensured.

  In each of the above-described embodiments, a two-lock type locking method is adopted, but the sliding door 1 and the locking device 10 of the present invention are also useful for the one-lock type locking method shown in FIG.

  In each of the embodiments described above, the connecting portion (locking part) between the locking body 21 and the lock receivers 30 and 50 is displaceable in any one direction in the sliding door opening / closing direction. If it is arranged on the front and back sides so that the lock holder can be held at the neutral position with respect to the bracket, the strength of the lock holder can be given in any of the sliding door opening direction and the sliding door closing direction. That is, the lock receiver may be provided so as to be displaceable in both directions of the sliding door opening direction and the sliding door closing direction.

  In the first embodiment described above, only the locking device having the strength in the compression direction is provided, and in the second embodiment, only the locking device having the strength in the pulling direction is provided. In consideration of the rigidity, etc., both may be installed in combination.

  In each of the above-described embodiments, for example, the lock receivers 30 and 50 are provided so as to be able to advance and retreat with respect to the vertical frame 2 in order to cope with the shaking of the earthquake. It may be provided so as to freely advance and retract. Furthermore, the lock receptacles 30 and 50 may be disposed on the sliding door main body 5 side, and the lock main body portion 20 may be provided on the vertical frame 2 side. Moreover, it can also comprise so that the whole locking device may move to a sliding door opening / closing direction. That is, as long as the connecting part between the lock receiver and the locking body is freely displaceable in the sliding door opening / closing direction, the connecting part may be displaced not only relative to the locking device but also with movement of the entire locking device.

  In each of the above-described embodiments, the gap C secured between the sliding door body 5 and the vertical frame 2 is not particularly touched with the width or the like, but the width may be changed in the vertical direction of the sliding door 1. Further, for example, an elastic body capable of compressive deformation may be provided in the gap C.
