問題となつている。[Problems to be solved by the prior art and the invention] Conventionally, so-called overhead doors, which are made by connecting a plurality of panels with a relatively large pitch so that they can be folded up and down, are opened and closed doors stored on the ceiling side. The door is opened and closed by winding and unwinding a wire whose tip is connected to the door side by driving a winding mechanism. For this reason, it is not possible to install the opening/closing winding mechanism in a place where there is no space to store it on the ceiling side, and since the opening/closing winding mechanism is located at a high place, it is difficult to install it during inspection and maintenance. There are disadvantages such as the need to work at heights. Moreover, when opening the door, the closer the door is to the fully open state, the smaller the tension on the wire becomes and the wire is more likely to come off the winding drum, which poses a problem as there is a limit to high-speed opening and closing.

In an overhead door constructed by bendably connecting panels and configured to move up and down along a guide rail extending above the opening, on the indoor side of the lowest panel among the panels, It is equipped with an electric opening/closing machine that is placed horizontally so that the drive shaft protrudes in the left and right direction, and a winding shaft that is chain-transmitted to a sprocket fixed to the drive shaft. , which is disposed at a position protruding outward from the left and right edges of the panel, and includes a winding drum for winding the wire, and the tip of the wire is integrally mounted on the ceiling of the frame. It is characterized in that the supported sliding body is supported so as to be movable in the left and right direction.

In the drawings, reference numeral 1 denotes a panel constituting an overhead door D, in which a plurality of panels 1, 1 are foldably connected via a connecting member such as a hinge 2. Guide rollers 3 are attached to hinges 2 at both ends of the panel 1, and the guide rollers 3 are guided by guide rails 4 extending on both sides of the building opening. Further, the upper part of the guide rail 4 is bent into an arc shape and is formed to run substantially parallel to the ceiling surface. Reference numeral 1a denotes a lowermost panel, and on the indoor side of the lowermost panel 1a, an electric switch 5 is installed in a horizontal state with a drive shaft protruding in the left-right direction and located approximately in the center, and below it. A winding shaft 6 is rotatably supported in the longitudinal direction by bearings 7, 7a, and a sprocket 6a fitted approximately in the center of the winding shaft 6 has a sprocket 6a fitted to the drive shaft of the opening/closing machine 5. installed sprocket 5a
The chain is connected to the chain. Further, a winding drum 8 is attached to both ends of the winding shaft 6 so as to protrude outward from the panel 1a, and one end of a wire 9 is attached to the winding drum 8.

The bracket 10a has mounting holes 10e in both raised sleeves and the base surface so that it can be selectively fixed to either a vertical wall of a building frame or a ceiling. . This sliding body 10c is disk-shaped and includes a wire connecting portion 10d, and the upper end of the wire is fixed to this connecting portion 10d.

能ならしめることになる。 In the embodiment of the present invention configured as described above, in order to open a currently closed door, when the opening/closing device 5 is driven by operating a push button switch (not shown), a chain is released from the sprocket 5a fitted to the output shaft. The rotation is transmitted to the sprocket 6a through the connection, and the winding shaft 6 disposed on the panel 1a rotates, so that the winding drums 8 at both ends move together to wind up the wire 9. Door 1 is pulled upwards. At this time, the heaviest bottom panel 1a, which is equipped with an opening/closing device, a winding shaft, and a winding drum, remains until the end and keeps the wire 9 under tension.
This effectively prevents the door from coming off, making it possible to open and close at high speed.

法を小さくできることになる。 In this way, although the electric switch 5 and the winding shaft 6 with a winding drum are provided on the lowermost panel 1a, the electric switch 5 is designed such that its drive shaft protrudes in the left-right direction. Since it can be installed horizontally, there is no need to make the panel 1a itself as wide as possible in the vertical width, and even if it is an overhead door that uses a panel with the smallest possible vertical width, The electric opening/closing machine 5 and the winding shaft 6 can be mounted on the panel side, and the size of the ceiling can be reduced.

来の如く高所作業が強いられることはない。 Furthermore, since the sliding body 10c can move in conjunction with the movement of the winding position of the wire on the hanging base side, it can be made even more suitable for high-speed opening and closing. In addition, since the structure does not have an opening/closing device, take-up shaft, or bullet device on the top, the size of the ceiling can be minimized, and it can be installed in places where it was previously impossible to install. This will greatly expand the marketability of overhead doors. Furthermore, since the opening/closing winding mechanism is provided on the lowermost panel, maintenance such as inspection and maintenance is easy, and there is no need to work at heights as in the past.

を提供できることになる。[Operations and Effects] In short, the present invention is constructed as described above, and although the electric switch and the winding shaft with the winding drum are provided on the bottom panel side, the electric switch Because the panel can be installed horizontally with the drive shaft protruding in the left-right direction, there is no need to make the panel itself as wide as it is vertically, which makes it possible to use panels with small vertical widths. Even in the case of the adopted overhead type door, an electric opening/closing machine and a winding shaft are attached to the panel side, so that it is possible to provide a structure in which the size of the ceiling can be reduced.

適なものになるという利点もある。 Moreover, the member that supports the tip of the wire on the frame side is a sliding body that can move in the left-right direction, and moves in conjunction with the left-right movement of the winding drum winding position of the wire. The winding shaft is located at the bottom panel, and the wire can be kept under tension at all times even when it is about to be fully opened.This, combined with the fact that it is even more suitable for high-speed opening and closing operations, is an advantage. .
