Conventionally, a chain type or electric type (hoist type) overhead door device has a wire rope 2 that suspends a door 1 wrapped around a winding drum 3, as shown in Fig. 1, and the winding drum 3 rotates. Door 1 is opened and closed. When the door 1 is lowered, the automatic lowering speed of the door 1 and the rotational speed of the winding drum 3 are synchronized, and the wire rope 2 is let out. However, if the wire rope payout speed is faster than the automatic lowering speed of the door 1, for example, the door 1 may fall on the horizontal rail 4.
If the wire rope 2 is supported above and the automatic lowering force is not sufficiently applied, the wire rope 2 will loosen more and more due to the rotation of the winding drum 3, and eventually fall off from the winding drum 3 and become unusable. become. Also, if the impact when the wire rope 2 falls is large, it will break and the door 1
It may also cause the object to fall.

なる。 From the stored state of the door 1 shown in Fig. 4, the winding cylinder 3
When lowering the door 1 while rotating the wire rope 2 and letting out the wire rope 2, if the wire rope 2 let out from the winding barrel 3 tries to loosen while the automatic lowering force of the door 1 is not sufficiently acting on the wire rope 2, ,
The tension roller 18 of the rotary plate 16 energized by the coil spring 13 pulls the wire rope 2 in the direction of winding it around the winding drum 3, thereby preventing the wire rope 2 from loosening and allowing the wire rope 2 to escape from the winding drum 3. Try not to. Then, when the door 1 gradually displaces from the horizontal direction to the vertical direction and its own weight descending force sufficiently acts on the wire rope 2, the wire rope 2 resists the turning force of the rotating plate 16 by the coil spring 13. When the tension roller 18 is pushed back and the door 1 is closed, the wire rope 2 is stretched in a straight line as shown in FIG. 5, the tension roller 18 is in a position circumscribing it, and the coil spring 13 is in a compressed state.

板１６を附勢させる。 In addition, when installing, a unit member A is formed which is fixed to the support shaft 12 by abutting the rotating plate 16 on which the tension roller 18 is attached to the attachment body 9 on which the support shaft 12 and the coil spring 13 are attached. One side piece 10 of the bracket 9 is welded and fixed to a bracket 8 protruding from the fixed wall 5. Before fixing the mounting member A, as shown in FIG. The pin 15 protruding from the shaft 12 is engaged to prevent the support shaft 12 from rotating, and after welding and fixing the one side piece 10 of the mounting body 9 to the bracket 8, the rotation stop pin 21 is pulled out and the support shaft 12 is The rotation force of the coil spring 13 is applied to further energize the rotation plate 16.

According to the present invention, there is provided a winding cylinder around which a wire rope connected to an overhead door is wound, a U-shaped mounting body protruding from a fixed wall facing one end of the winding cylinder, and this mounting body. a support shaft that is suspended parallel to the winding cylinder between both sides of the winding cylinder and is biased in one direction of rotation by a coil spring; a rotating plate that has its upper end fixed to the support shaft; a tension roller protruding from the lower end of the rotary plate at a slightly lower position of the winding cylinder parallel to the axial direction and pulling out from the winding cylinder and urging the wire rope in a direction to wind it around the winding cylinder; As a result, when the door is pulled out, if the speed at which the wire rope is fed out from the winding barrel is faster than the automatic lowering speed of the door, the tension roller winds up the wire rope via a rotating plate energized by a coil spring. Since the wire rope is rotated in the direction of winding it around the trunk and the wire rope is prevented from becoming slack, the wire rope will not escape from the winding trunk or be cut off by the sudden drop of the door. In addition, since the support shaft, coil spring, and rotating plate are attached to the mounting body, it can be easily mounted by simply fixing the mounting body to the bracket, and it can be easily mounted to an existing overhead door device.
