Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a fixing device for a central pillar of an electric shutter for a building.

[Problems to be Solved by Prior Art and Invention] In general, in the case of a building having a wide opening width, the shutter curtains are connected to the left and right for convenience of the shutter strength and the like.
In such a thing, the center pillar will be provided in a standing shape in the continuous portion, but if the shutter curtain is lowered in a state where the center pillar is not fixed at a predetermined position, there is a problem that the shutter curtain comes off. is there.

Therefore, conventionally, as shown in Japanese Examined Patent Publication No. 62-45387, it is activated by detecting that the center pillar is locked at a predetermined position,
Some have been designed to safely raise and lower the shutter curtain. However, in this thing, since the fixing device is provided so as to project from the front and rear surfaces of the center pillar, when suspending so that the center pillar can be moved in the left and right direction, this suspension device moves forward and backward beyond the fixing device. It is necessary to further project the center pillar, and as a result, the center pillar is greatly tilted in the front-rear direction in the hanging state where it is not locked, which makes it easier for the lifting device to come off, and the lower end of the center pillar must be aligned. This is a problem because it is troublesome and the workability is extremely poor.

[Means for Solving the Problems] The present invention was conceived with the object of providing a fixing device for a central pillar of an electric shutter for a building that can eliminate these drawbacks in view of the above-mentioned circumstances. At the middle pillar of the electric shutter for a building, which is provided in a standing shape in the continuous portion of the shutter curtains that are arranged on the left and right, and guide portions that guide the raising and lowering of the shutter curtain are formed on the left and right sides, A fixing device for fixing the center pillar to a predetermined position is provided at least on the upper part of the center pillar, and is vertically moved to a lock position where a tip portion projects from the center pillar and a lock release position retracted to the center pillar side from the lock position. A locking rod provided for directional movement operation, an engaging portion provided on the building for engaging the locking rod that is operated to project to the locking position with the center pillar set at a predetermined position, and the engaged locking rod. The lock rod is arranged at an inward position that is sandwiched between the left and right guide portions and does not project from the front and rear surfaces of the center column. It is a thing.

According to the present invention, the present invention makes the vertical position as close to the vertical posture as possible even when the center pillar is in the suspended state.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings. In the drawings, 1 is a shutter curtain, 2 is a vertical rail that is fixed to the building side and guides the curtain 1, 3 is a moving pillar mounted between the curtains 1 and 4, and 4 is a storage case of the shutter curtain 1. is there. The moving middle pillar 3 is mounted on a traveling rail 5 provided on the outer side of the lower side of the storage case 4, and a lifting device 6 is provided.
It is possible to move to the building side (vertical rail 2 side) via. Locking devices 7 and 8 which will be described later are provided at the upper and lower ends of the center pillar 3 and are connected by a link mechanism or the like.

The moving center pillar 3 is a back-to-back guide portion 31, 32 for guiding the vertical movement of the left and right curtains 1, and the left and right guide portion 3
It is composed of a prismatic columnar body 33 sandwiched between 1 and 32. An upper lid 34 is provided on the upper surface of the column body 33, and a through hole 35 through which a lock rod 78 described later appears and disappears is formed in the central portion of the upper lid 34. Further, a mounting base 63 of the lifting device 6 is provided on the indoor side above the moving middle pillar 3, and a suspension shaft 62 is rotatably erected upward from the mounting base 63 so as to be suspended. axis
At the tip of 62, a hanging roller body 61 that is rotatably integrated into the left and right
Is rotatably supported, and the hanging roller body 61 rolls on the traveling rail 5. The center pillar 3 is rotatable about the suspension shaft 62 with respect to the traveling rail 5.

Reference numeral 9 denotes an L-shaped handle which is attached to the interior pillar 3 at a convenient indoor position for easy operation, and a handle stopper 91 is provided inside the interior pillar 3 so that the handle 9 does not rotate too much. 73 and 74 are Z-shaped and plate-shaped levers.
73 is fixed to the rotary shaft of the handle 9, one end of a lever 74 is pivotally supported at the center of a hook-shaped connecting piece 72, and the other end is pivotally supported at the lever 73. Upper and lower connecting rods 71 and 81 are connected to the upper and lower ends of the connecting piece 72 so that their lengths can be adjusted. Then, the upper end of the upper connecting rod 71 is connected to an angled link 77 that can move up and down via a link 76 pivotally supported at the central portion 75, and further at the tip of the link 77 (the central portion of the center pillar 3). An upper lock rod 78 is connected so as to be slidable up and down, and constitutes the upper lock device 7.

On the other hand, a slide cover 83 and a bifurcated lower lock rod 82 are fixed to the lower portion and the lower end of the lower connecting rod 81 constituting the lower lock device 8, and the lever is operated by the rotation of the handle 9. The lower connecting rod moves up and down by 73, 74,
Thereby, the cover 83 is pushed down to the floor surface to eliminate the lower clearance between the floor surface and the center pillar 3, and the lock rod 82 is operated to lock the cover 83.

A detection switch 10 is provided at the center of the traveling rail 5. The lock rod 78 is pushed up by the operation of the handle 9 with the center pillar 3 set to the predetermined position, and the tip end portion is located at the lock position where it projects toward the traveling rail 5. Then, the tip of the lock rod 78 just comes into contact with the actuator 11 of the detection switch 10, and the detection switch 10 is positioned so as to activate the detection switch 10. The detection switch 10 is connected to a power supply circuit of a shutter driving device (not shown), and is set so that the shutter curtain is opened and closed only when the completion of the locking of the center pillar 3 is detected.

In the embodiment of the present invention constructed as described above, first,
Fully open the closed shutter curtain 1. When the handle 9 provided on the indoor side of the middle pillar 3 is turned in the unlocking direction, the link mechanism such as the levers 73 and 74 and the connecting piece 72 causes
The upper and lower connecting rods 71, 81 are pulled to the handle side, whereby the upper lock rod 78 descends so as to be disengaged from the traveling rail 5, and retracts into the center pillar 3 to release the lock. And the lower lock rod 82 and the slide cover 83 rise to the lock release position where they are retracted into the center pillar 3, and the upper and lower mechanical locks are released, but the upper lock rod is released. As the 78 is disengaged from the traveling rail 5, the contact of the detection switch 10 at the tip of the lock rod is released from the actuator, and the detection switch 10 is turned off, thereby opening the shutter power supply circuit. In this state, the shutter curtain 1 cannot be opened / closed by the push button or the like. At this point, the middle pillar 3 is completely suspended by the traveling rail 5, that is, the center of gravity of the middle pillar 3 is in a state of being displaced to the indoor side with respect to the suspension shaft 62, but the middle pillar 3 is suspended. axis
If it is turned 90 degrees with respect to 62, the center of gravity of the center pillar 3 shifts to the line of the traveling rail 5, and it can be moved to the storage position on the building side with less traveling resistance, and if necessary, it will return to its original state by rotation By doing so, the storage space can be made extremely compact.

Next, in order to set the middle pillar 3, contrary to the above, up to a predetermined position (until it hits the door stop 51 provided on the traveling rail 5)
When the center pillar 3 is moved and rotated by 90 degrees, and then the handle 9 is operated to the lock side, the upper and lower connecting rods 71 and 81 move up and down, and the upper lock rod 78 penetrates the through hole 35 of the upper lid 34 and moves upward. Projecting to the lock position and its tip is the detection switch 10
It comes into contact with and is turned on, and at the same time, the lower lock rod 82
Then, the slide cover 83 descends and the lock rod 82 is located at the lock position where it is fitted into the lock hole 20 provided on the floor surface, whereby the setting of the center pillar 3 is completed. At this time, if either of the upper and lower locking rods 78 and 82 cannot be fitted into the opponent side, the handle 9 will not turn,
You can easily know this, and at that time you can correct the position of the center pillar 3, there is no fear of forgetting to lock. Further, when the slide cover 83 descends, no gap is created between the center pillar 3 and the floor surface, and the appearance is not deteriorated.

In this way, in the case where the present invention is implemented, the central pillar 3
Is set to the predetermined position and the lock rod 78 is operated to lock, the switch 10 detects the lock operation and can open / close the shutter curtain. Since it is provided on the inner side of 3 instead of on the side, it is not necessary to provide the suspending device 6 beyond the locking device 7 and project further outward when the suspending device 6 is mounted. Can be mounted as close as possible to. As a result, the center pillar 3 suspended in a cantilever manner by the suspension device 6 can be maintained in a posture close to vertical without being significantly inclined in the front-rear direction. Further, as in the present embodiment, since the center pillar 3 is rotatable about the suspension shaft 62, the lock rod 78 of the center pillar 3 on the traveling rail 5 line can be positioned, and the vertical lifting can be ensured. The posture can be maintained, the movement can be performed smoothly and lightly, and the locking operation on the lower end side can be greatly simplified.

Moreover, since the upper and lower ends can be locked by operating the handle 9, the set of the center pillar 3 can be further simplified and the operation can be remarkably improved.

Further, in the embodiment, since the handle 9 is in a posture of hanging downward when locking, there is a problem that the handle 9 is inadvertently moved by vibration and the lock is released when the shutter is moved up and down. However, the certainty is being improved.

[Advantages] In short, since the present invention is configured as described above, when the central pillar is fixedly locked at a predetermined position, the detection switch has a locking rod that is operated to project at the locking position.
The lock rod is arranged at a position where it does not project from the front and rear surfaces of the center pillar, although it is possible to detect and move the shutter curtain up and down. Therefore, when the suspension device is provided on the center column, the suspension device can be mounted as close as possible to the front and rear surfaces of the center column without being obstructed by the locking rod. When the center column is suspended, the front-rear tilt is significantly reduced, and it can be maintained in a posture that is almost vertical, so as to prevent the suspension device from coming off from the traveling rail, and when locking the center column. Since the lower end position of the can be easily aligned, the workability can be remarkably improved.
