Description

  The present invention relates to a technical field of an electric shutter device for building provided in an opening of a building.

In general, in an electric shutter device for construction, a shutter case provided above an opening is equipped with an opening / closing device that drives to open and close a shutter curtain, and a control device for controlling the driving of the opening / closing device, There is a configuration in which the shutter curtain is opened and closed by forward and reverse driving of the opening and closing machine based on the control of the control device. Furthermore, in such an electric shutter device for construction, a counter that counts and displays the number of times the shutter curtain is opened and closed is used so that the number of times the shutter curtain is opened and closed can be used as information for judging the timing and contents of maintenance. There is something provided. In this device, the counter is connected to, for example, a control device that performs drive control of the switch, or a power transmission mechanism that transmits power from the switch to the take-up drum. Conventionally, a counter is disposed in a shutter case in which a control device and a power transmission mechanism are installed (for example, the conventional technique described in Patent Document 2). However, when the counter is arranged in the shutter case in this way, the user must open the shutter case one by one when checking the number of times of opening and closing, and this operation is cumbersome and prone to neglect, and maintenance is required. There is a problem that the number of times the shutter curtain is opened and closed, which is information necessary for determining the timing and content of the shutter, cannot be used effectively.
In order to know the information based on the number of times the shutter curtain has been opened and closed without opening the shutter case, a counting means for counting the number of times the shutter is opened and closed is incorporated in the control device, while a display lamp for displaying the counted information is opened and closed. What was provided in the operating panel in which the pushbutton switch for operation is provided is known (for example, refer patent document 1).
In addition, an operation notification unit that detects the opening / closing operation of the shutter curtain and irradiates infrared rays is disposed on the shutter curtain, while a counter device is disposed on a guide rail or the like in a dynamically changeable state, and the operation is performed by the counter device. There has also been proposed a technique for receiving infrared rays from a notification unit and counting and displaying the number of times the shutter curtain is opened and closed based on the reception (see, for example, Patent Document 2).

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
In the drawings, 1 is a shutter curtain of a high-speed sheet shutter device (which is an example of an electric shutter device for building of the present invention) that opens and closes an opening formed in the building housing B to partition the inside and outside of the building, The shutter curtain 1 is made of a flexible sheet material and is wound around a winding drum 3 that is rotatably mounted in a shutter case 2 disposed above the opening. As will be described later, the winding drum 3 is linked to an opening / closing machine 4 provided in the shutter case 2, and the shutter curtain 1 wound around the winding drum 3 is driven to open / close the opening / closing machine 4. The position of the opening is changed between the fully closed position in which the opening is closed by being unwound from the winding drum 3 and the fully open position in which the opening is opened by being wound around the winding drum 3. At this time, the left and right side edges of the shutter curtain 1 are set so as to be moved and guided by a pair of left and right guide rails 5 fixed to the chassis B on both sides in the left and right direction of the opening, All of these basic configurations are the same as before.

The shutter curtain 1 is provided on the outer edge of the sheet material 1a forming the shutter curtain 1 in the left-right direction with a plurality of locking pieces 1b having a predetermined gap in the vertical direction. As will be described later, these locking pieces 1b are configured to be fitted on the guide rail 5 in a retaining shape and receive vertical movement guidance. Further, a bag-like bottom portion 1c is formed by folding back the sheet material 1a at portions other than the left and right end portions of the lower end edge portion of the shutter curtain 1, and the bottom portion 1c is long in the left-right direction. A bottom weight 1d having a rigidity capable of receiving a load evenly regardless of the sandwiching position when the obstacle is sandwiched is provided so as to be hardly bent in the vertical direction (height direction). Thus, in the process of closing the shutter curtain 1, the bottom weight 1d acts as a weight to facilitate the closing operation described later. Here, the bottom weight 1d of the present embodiment is set so as to be long in the left-right direction and to cover the full width of the opening, and is formed of a plate-like bottom sheet material 1g having a width in the up-down direction. Since a laminated material in which a plurality of sheets (for example, 4 sheets) are stacked in the front-rear direction in a vertical posture is incorporated in the bottom portion 1c and integrated through the bolt 1e, there is almost no vertical deflection. . The bottom portion 1c is covered with a bag-like cover portion 1f. The bottom sheet material 1g is one or any combination of non-metallic materials such as asphalt, rubber, and resin materials. Among these, a metal material (metal powder, metal wire) is used to increase the specific gravity. , Metal balls, metal pieces, metal sheets, etc.) can be mixed or fixed. More specifically, in this embodiment, asphalt mixed with iron oxide (Fe ₂ O ₃ ) powder and calcium carbonate (CaCO ₃ ) is formed into a plate-like body, and a non-woven fabric made of polyester is attached to the surface. We adopt what we did.
Incidentally, since the shutter curtain 1 is only provided with a bottom weight 1d at the lower end portion and has no aggregate in the middle portion in the vertical direction, only the bottom weight 1d is used as a weight for lowering its own weight. It is set so as to contribute (the sheet material constituting the shutter curtain 1 hardly contributes as a weight for dropping its own weight).

  Further, a pair of left and right long guide rails 5 provided on both sides of the opening are L-shaped rail brackets 6a that are positioned on the left and right sides of the opening and fixed to the housing B, respectively, and the rail brackets A vertically elongated first rail 6 formed by an inverted L-shaped rail cover 6b that forms a rectangular tube-shaped space facing the 6a, and provided inward in the left-right direction of the first rail 6. An up-and-down elongate closing sheet 7 curved in an arc shape, and locking pieces 1b provided on both sides of the shutter curtain 1 located on the left and right inner sides of the closing sheet 7 are vertically movable, and And a second rail 8 that fits in a state in which it is prevented from being removed in the left-right direction.

  The second rail 8 is made of an elastically deformable resin material, is formed in a long body having a length from the floor surface to the lower end portion of the shutter case 2, and the shutter curtain 1 extends inward in the left-right direction. A guide piece 8a that fits and guides the locking piece 1b is formed over the entire length in the vertical direction, while a bolt support piece 8b that fits and supports the head portion 9a of the bolt 9 in the left-right direction so as to prevent left-right direction. It is formed over the entire length in the vertical direction. The second rail 8 configured as described above is configured such that the head portions 9a of the plurality of bolts 9 are fitted to the bolt support pieces 8b, and the screw portions 9b protruding outward in the left-right direction of the bolts 9 are Each rail 6 is inserted into the rail bracket inner side surface 6c so as to be freely movable in the left-right direction, and a nut 9c is screwed into a penetrating end portion of a screw portion 9b protruding into the square tube of the first rail 6. Thus, it is assembled in a state of being prevented from coming off from the first rail 6. Further, a coil 9d is provided on the outer periphery of the screw portion 9b of the bolt 9 located in the square tube of the first rail 6 and between the rail bracket inner side surface 6c and the nut 9c. The bolt head 9a is urged outward in the left-right direction by the urging force of the coil bullet 9d.

  Thus, the second rail 8 is supported in a state where the bolt support piece 8b is elastically pressed against the rail bracket inner side surface 6c, and when the load due to wind pressure or the like acts on the shutter curtain 1, the load becomes a predetermined magnitude. If it is within this range, the second rail 8 swings in the front-rear direction together with the bolt 9, and further, the second rail 8 moves inward in the left-right direction together with the bolt 9 against the urging force of the coil bullet 9d. Therefore, the deformation of the shutter curtain 1 is allowed without the locking piece 1b being pulled out from the guide piece 8a of the second rail 8, and the load acting on the shutter curtain 1 is larger than a predetermined magnitude. When it is large, the locking piece 1b is extracted from the second rail 8 based on the elastic deformation of the guide piece 8a, and the shutter curtain 1 and the second rail 8 can be protected. It has been.
