DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door locking device which is particularly useful for holding a large door in a proper closed position.

[0002]

2. Description of the Related Art In order to selectively partition an indoor space, a moving partition device has been conventionally developed and put to practical use. The moving partitioning device includes a ceiling rail laid on an indoor ceiling, a moving wall suspended and supported on the ceiling rail, and a moving wall provided at a position continuous with the ceiling rail and moving the moving wall along the ceiling rail. Usually, it is provided with a storage section for storing after being made. The storage portion has an opening having a width sufficient to allow the moving wall to move at least in the plane direction and pass therethrough, and a door is provided at a position to open and close the opening. Then, after moving the moving wall to the use position or the storage position, it is general that the door is closed and the door forms a part of the indoor wall surface.
In addition, the door is usually provided with a lock device having a protruding and retracting element that protrudes and retracts from the upper edge and the lower edge in opposite directions to simultaneously engage or disengage with the ceiling surface and the floor surface, respectively. Yes, the door is held in that position by activating the locking device when the door is closed.

[0003]

By the way, as a moving partitioning device applied to a hotel floor or the like, there are many giant devices having a moving wall with a height of 10 m or more. Along with this, it is customary for the door of the storage unit to have an irregular shape whose height is extremely large with respect to the width. Therefore, in such a door, there is a problem that it is easy to cause warpage or distortion, and it is difficult to properly arrange and lock the opening at a position where the opening is closed. In other words, with this type of large door, it is necessary to press the vicinity of the lower edge of the door when performing the closing operation, and it is necessary to transmit the operating force to the entire door using the rigidity of the door. However, when a local operating force is applied to the biased position of the door in this way,
While the operating force is reliably transmitted to the vicinity of the lower edge of the door at a relatively close position, it is difficult to transmit the operating force to the vicinity of the upper edge of the door at a position far from the operation location. For this reason, even if the lower edge is properly pushed into the position for closing the opening, the vicinity of the upper edge may not reach the closed position merely by causing the entire door to warp or warp, and may be left in a floating state. There are many. Therefore, even if an attempt is made to operate the door locking device in such a situation, the locking device may not be able to function effectively.

[0004]

SUMMARY OF THE INVENTION To solve the above problems, the present invention provides for the door edge to be synchronously engaged with a corresponding opening edge at a plurality of locations along the edge. For this purpose, engaging portions are provided at a plurality of positions so as to be able to protrude and retract, and these engaging portions are driven by a common operating shaft to simultaneously engage with the corresponding engaged portions. And at the time of the engagement,
The operation of correcting the twist of the door is performed between the engaging portion and the engaged portion. For this reason, even when the door is warped or distorted, the engagement operation between the engaging portion and the engaged portion serves to correct the door to an appropriate closing posture, and as a result, the warpage and distortion gradually occur. The door is moved to the proper closing position and locked while being canceled.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A door lock device according to the present invention comprises:
In order to selectively lock the edge of the door, which can be opened and closed at the opening, on the side opposite to the hanging side to the corresponding opening edge in the closed position, the edge on the side opposite to the hanging side of the door or the corresponding opening edge. On one of the two, the working axis arranged along the edge and the working axis
Operating handle and intermittently arranged along the edge
It operates in the direction perpendicular to the edge and can be protruded from the edge
A plurality of engaging portions located on the upper edge side from the operation handle are arranged, and the operation of this operating shaft is simultaneously converted to the synchronized protruding and retracting operation of each engaging portion via the operation converting portion, The protruding engaging portion is configured to be engaged with an engaged portion provided on the other edge of the door on the side opposite to the hanging side or the corresponding opening edge, and at the time of the engagement, the engaging portion is engaged. It is set so that the action of gradually correcting the torsion of the door from the lower edge toward the upper edge between the portion and the engaged portion is performed.

The setting for performing the action of correcting the torsion of the door includes a tapered surface between the engaging portion and the engaged portion for urging the door toward the closing position in accordance with the projecting operation of the engaging portion. It is effective to provide a guide roller.

In a preferred embodiment of the operation shaft and the motion conversion unit, the operation shaft is a rotation shaft, and the operation conversion unit converts the operation of the rotation shaft into a retraction / retraction operation of the engagement unit in the reciprocating direction. A pinion mechanism may be used. In this case, it is preferable that an operation handle is provided on the face plate portion of the door so as to be rotatable around an axis orthogonal to the rotation axis, and the operation handle is converted into a rotation operation of the rotation axis via a worm mechanism.

With such a structure, when the vicinity of the lower edge of the door is pushed into the predetermined closing position, the door is warped or distorted, and the vicinity of the upper edge of the door reaches the predetermined closing position. Even when the operating shaft of the present invention is operated, even if the operating shaft of the present invention is actuated, the engaging portions start to protrude in synchronization with each other via the operation converting portion, and a plurality of the engaging portions start from one edge of the door or the opening. Are simultaneously projected and engaged with the engaged portion on the other edge.
During this time, the warpage and distortion of the door are gradually corrected. That is, the lock device of the present invention guides the door in the incompletely closed state to the appropriate closed position, and then reliably performs the operation of locking the door to the opening edge.

Particularly, when a tapered surface or a guide roller is provided between the engaging portion and the engaged portion, an initial stage in which the engaging portion protrudes due to the wedge action of the tapered surface or the guiding action of the guide roller. Has a small biasing force to the closed position against the door,
Since the urging force is gradually strengthened with the subsequent protruding operation, even if the door has relatively large warpage or distortion and the gap from the closed position is large, move the door to the appropriate closed position and lock it. Becomes possible.

The opening is locked to the corresponding opening edge 41b of the face plate 5b via the locking device 8.

As shown in FIGS. 3 to 7, the lock device 8 includes a gear unit 81, a rotating shaft 82 as an operating shaft,
It comprises a handle unit 83 and a guide roller unit 84.

The gear unit 81 is, as shown in FIG.
The gear box 811 is fixed at four places in the vertical direction on the back side of the door 1 along the edge 11 on the side opposite to the hanging side of the door 1 via a gear box 811, as shown in FIG. As described above, the engaging claw 812 as the engaging portion of the present invention and the rack and pinion mechanism 813 as the operation converting portion are provided inside. That is, a pinion 813a is provided inside the gear box 811 so as to be rotatable about a vertical axis, and a rack 813b is provided at a position meshing with the pinion 813a. While penetrating the box 811 and extending horizontally to both ends,
The engaging claw 812 is integrally attached to one of the extending ends. Then, when the pinion 813a rotates, the rack 813b moves forward and backward, and the engaging claw 812 projects substantially sideways from the edge 11 on the side opposite to the suspension base, and substantially sinks into the inside of the edge 11. To be driven forward and backward. The engaging claw 812 has a tapered surface 812b that becomes gradually thinner at the front end side of the back surface 812a. The gear unit 81 includes the engaging claw 81.
A plurality of guide rollers 814 are axially mounted in an array around an axis orthogonal to the advance / retreat direction along the second advance / retreat trajectory.
These guide rollers 814 are attached to the rear surface 81 of the engagement claw 812.
2a, it assists the forward / backward movement and prevents floating.

As shown in FIGS. 4 and 5, the rotating shaft 82 is vertically disposed through the gear box 811 of each gear unit 81.
1, and is connected to the pinion 81a provided therein so as to be integrally rotatable.

As shown in FIGS. 4, 6, and 7, the handle unit 83 includes a gear unit 8 disposed at the lowermost position.
The operation handle 831 is attached to the back surface of the face plate portion of the door 1 at a position lower than 1 and is rotatably disposed around an axis 831a orthogonal to the rotation axis 82. A worm mechanism 832 connected to the rotary shaft 82 via a shaft 831a.
That is, the worm mechanism 832 includes a worm 832a attached to the shaft 831a so as to be integrally rotatable, and a worm wheel 832b disposed at a position meshing with the worm 832a.
2b is disposed on the same axis as the pinion 813a,
The rotation shaft 82 is connected so as to be integrally rotatable.

The guide roller unit 84 serves as an engaged portion of the present invention. As shown in FIGS. 2 and 3, the guide roller unit 84 has an anchor at a position corresponding to each gear box 81 on the back surface of the building wall W. It is fixed and part of it is the building wall W
, And a space S is formed between the protruding portion and the rear surface of the fixed face plate 5b so that the engaging claw 812 is inserted and removed. A guide roller 841 is axially mounted on the protruding end about a vertical axis. An outer peripheral surface on the front end side of the guide roller 841 is set so as to be on an extension of the guide roller 814 of the gear unit 81 in the arrangement direction.

That is, as shown by the imaginary line (thick line) in FIG. 3, the locking device 8 of this embodiment makes the engaging claw 812 b projecting from the edge 11 on the side opposite to the hanging side of the door 1 into a corresponding opening. By engaging a guide roller 841 provided on the edge 41, the door 1 is held at the closed position and locked.

When the door 1 provided with such a lock device 8 is employed, the operator who has entered the storage section 4 moves from the open position shown in FIG. 1 to the closed position near the lower edge 12 on the back side of the door 1. When the lower edge 12 is pushed into a predetermined closed position as shown by a solid line in FIG. 3, the upper edge 13 does not follow the lower edge 12 due to the warpage or distortion of the door 1 and is imagined in FIG. Even if the user does not reach the predetermined closed position and rises as shown by the line (thin line), the operating force is applied to the gear unit 81 by operating the operating handle 82 from the position to operate the operating shaft 82. Each engaging claw 8
This is converted into a synchronized sideward projecting operation, and the engaging claws 812 simultaneously project and engage with the guide rollers 841 located at the corresponding opening edges 41b. Then, by synchronously operating the large number of engaging claws 812 in this manner, the door 1
Are corrected sequentially from the lower edge 12 side to the upper edge 13 side. In particular, since the engaging claw 812 is provided with a tapered surface 812b, and the tapered surface 812b is gradually and deeply taperedly engaged with the guide roller 841 together with the projecting operation, the wedge action of the tapered surface 812b and the operation of the guide roller 841 are performed. By the guiding action, the engaging claw 8
The urging force of the door 1 toward the closed position is small at the initial stage when the door 12 protrudes, and the urging force is gradually increased with the subsequent protruding operation. Accordingly, even when the door 1 is relatively warped or distorted and the gap from the closed position is large, the door 1 can be guided to the appropriate closed position and locked. For this reason, the closing operation of the door 1 is smoother and more reliable than a conventional locking device that simply protrudes and retracts the protruding and retracting members provided on the upper and lower edges of the door with respect to the ceiling surface and the floor surface. And a locked state can be realized, which can be extremely useful when applied to a huge door 1 as in this embodiment.

The rotating shaft 82 is employed as an operating shaft, and a rack and pinion mechanism 813 is employed as an operation converting unit for converting the operation of the rotating shaft 82 into a reciprocating operation of the engaging claw 812 in the reciprocating direction. Therefore, even with a simple configuration, it is possible to ensure proper synchronization of the engagement claws 812. Further, an operation handle 831 rotatable around an axis orthogonal to the rotation shaft 82 is provided on the face plate portion of the door 1, and the operation handle 831 is attached to the rotation shaft 8 via a worm mechanism 832.
Since the rotation operation is converted to the second rotation operation, the operability can be improved, and at the same time, the inconvenience that the operation handle 831 is accidentally reversely driven by the load on the rotating shaft 82 can be surely prevented. .

The specific configuration of each part is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, in the above embodiment, the engaging claw 812 is provided on the door 1 side, and the guide roller 8
41 is provided on the side of the opening edge 41b,
Is provided on the side of the opening edge 41b, and the guide roller 841 is
It may be provided on the side.

[0025]

The present invention is embodied in the form described above and has the following effects.

That is, in the door locking device according to the present invention, the door edge can be protruded and retracted at a plurality of locations so as to synchronize with the corresponding opening edge at a plurality of locations along the edge. Are provided, and these engaging portions are driven by a common operating shaft to simultaneously engage with the corresponding engaged portions. Then, during the engagement, the torsion of the door between the engaging portion and the engaged portion is performed from the lower edge toward the upper edge.
It works to gradually correct it. For this reason, even if the door is warped and distorted, the door can be moved to the appropriate closing position and locked, and can be extremely useful especially when applied to a large-sized door.

In particular, by providing a tapered surface or a guide roller between the engagement portion and the engaged portion that urges the door toward the closing position in accordance with the projecting operation of the engagement portion, these members are provided. The incompletely closed state of the door can be more effectively corrected by the wedge action and the guide action, and the above-described action and effect can be made more effective.

In the case where the operation shaft is a rotation shaft, and the operation conversion unit for converting the operation of the rotation shaft into the retracting operation of the engagement unit in the forward and backward directions is constituted by a rack and pinion mechanism, a simple configuration is appropriate. Operation can be secured. In this case, an operation handle that is rotatable about an axis orthogonal to the rotation axis is provided on the face plate portion of the door, and the operation handle is converted into a rotation operation of the rotation axis via a worm mechanism so that the operation can be performed. At the same time, the inconvenience that the operation handle is accidentally reversely driven by the load on the rotating shaft side can be surely prevented.
