ツター装置に関する（IPC：E06B）。[Detailed Description of the Invention] (Technical Field) The present invention relates to a shutter device equipped with means for preventing the shutter from loosening due to the shutter being fed out by more than a predetermined amount from the winding drum when the shutter is fully closed. (IPC:E06B).

なかつた。(Prior art) Even if the shutter body is fed out a predetermined amount from the take-up drum and the seat plate at its lower end hits the floor, etc., the take-up drum does not stop immediately due to its own weight, inertia, etc.
The shutter slat is still unwound from the take-up drum, and the shutter body may become slack. On the other hand, some electric shutter devices have been known in the past, in which the amount of feed of the shutter body is detected using a micro switch, and based on this, braking is applied to the winding drum in advance. ing. However, even with this, the stopping position may shift depending on the degree of inertia and the effectiveness of braking. This is especially true for smoke-proof shutters that automatically lower and close under their own weight in the event of a fire. It was not possible to prevent the seeds from loosening.

する。(Purpose of the invention) The invention is designed to ensure that when the shutter is fed out a predetermined amount, the torque around the take-up drum based on the weight of the shutter body is canceled out, and the shutter body is reliably stopped at a predetermined fully closed position. It is an object of the present invention to provide a shutter device that does not cause slack.

に従つて本考案を詳細に説明する。(Structure of the invention) That is, the present invention has a shutter main body 1 whose winding start end 2 is fixed to a winding drum 3.
and a winding drum for winding up the shutter body; one end of the shutter body is fixed to a point separated by an appropriate distance from the winding start end, and the other end is fixed to the winding drum. In a shutter device equipped with a flexible tensioning means 4, the flexible tensioning means has a length that is tensioned when the shutter is fully closed, and the winding direction with respect to the winding drum at that time is the same as that of the shutter body. It is characterized in that it is the opposite of Hereinafter, the present invention will be described in detail according to embodiments shown in the drawings.

る。(Embodiment) In the illustrated embodiment, numeral 1 denotes a shutter body formed by connecting a number of slats, and its winding start end 2 is fixed to a winding drum 3. 4
are two wire ropes on the left and right that are tensioned when the shutter body is extended a predetermined amount and are in a predetermined fully closed position to prevent the shutter body from further lowering; Mounting piece 5 provided on the fourth slat from the end
Each other end is fixed to the same point of the winding drum where the winding start end 2 of the shutter body is fixed from the direction opposite to the winding direction of the shutter body. Therefore, when the shutter main body 1 is unwound by a predetermined amount from the winding drum 3 and descends to a fully closed state, the wire rope becomes taut and prevents the shutter main body from further descending. Note that if the winding drum is rotated from this fully closed state in the opposite direction in the direction of winding up the shutter body, the wire rope will be wound around the winding drum in the same way as the shutter body after it becomes a little slack.
