【考案の詳細な説明】
この考案は相平行する複軸シヤツターを以て全
体を小型化し、且つ軽快に昇降せしめる複軸シヤ
ツターの開閉装置に関するものである。[Detailed Description of the Invention] This invention relates to an opening/closing device for a multi-shaft shutter, which has parallel multi-shaft shutters, is miniaturized as a whole, and can be moved up and down easily.
従来この種の複軸によるシヤツターの開閉装置
においては、シヤツターを全部捲上げて全開放し
た時に、シヤツターが複軸に対して全重量を荷重
するため、次に操作であるシヤツター閉鎖降下の
作動が不可能となるか、または、作動が著しく遅
延する等の欠点がある。 Conventionally, in this type of multi-shaft shutter opening/closing device, when the shutter is fully rolled up and fully opened, the entire weight of the shutter is applied to the multi-shaft, so the next operation to close and lower the shutter is difficult. However, there are drawbacks such as impossibility or significant delay in operation.
そこで、この考案はこの様な従来の欠点を改良

の昇降操作を極めて敏捷容易とする効果と、全体
に無理が係らず、長期間の使用に際してもガタ付
や破損する等の憂いがなく安心して使用できる効
果がある。 Therefore, in order to improve these conventional drawbacks, this invention was developed by changing the installation positions of the guide shaft located at the front and the winding shaft located at the rear inside the flat shutter case to a position above the axis of the guide shaft. The bearings are placed parallel to each other. An endless pulley is constructed by fitting and fixing a pulley to the guide shaft and winding shaft from the outer periphery.
A pulley protection foil is fixed to the outer periphery of the guide shaft and the winding shaft with a gap having the width of the endless tuning band on both sides of the pulley. The upper end of the shutter is connected to this endless belt. Further, a shaft sprocket is pivotally supported at the end of the winding shaft, and the shaft sprocket is connected to the opening/closing machine via a drive chain. In addition, a shutter slat loosening prevention device is installed, which has a rotating portion extending below the guide shaft and the winding shaft. Therefore, this invention has the effect of making the lifting and lowering operation of the multi-shaft, which was difficult to open and close with conventional shutters, extremely agile and easy, and the entire structure is not strained, and there is no wobbling or damage even during long-term use. It is effective and can be used with peace of mind without any worries such as.

A flat shutter case 4 of various shapes is installed on a wall surface 24 such as an entrance/exit of a building or a window frame. Inside this case 4, a guide shaft 2 is provided at the front of the lifting side of the shutter 1, and a winding shaft 3 is located parallel to the guide shaft 2 at a position above the guide shaft 2 behind it. It is supported by bearings 14, 14. The guide shaft 2 and the winding shaft 3 are provided with endless adjustment bands 9, 9 at several locations, each with pulleys 7, 8 fitted and fixed from the outer periphery. A gap the width of the endless tuning band 9 is provided on both sides of the pulleys 7 and 8, and a pulley protection foil 1 is provided around the outer periphery of the guide shaft 2 and the winding shaft 3.
8 and 18 are fixed. Further, a roller-equipped support 21 having rollers at both ends that supports the distance between the guide shaft 2 and the winding shaft 3 is fixed to a construction shaft constructed on the side walls 5, 5. Next, one of the guide shafts 2 is provided with a restoring spring portion 6 inside. This restoring spring section 6 has a winding wheel 11 fixed to an internal fixed shaft 10 and an adjustment wheel 12 attached to the end of the guide shaft 2, and a number of Winding springs 13, 13 of the strips are interposed. Next, a shaft sprocket 15 is fixed to the end of the winding shaft 3, and
It is connected to the opening/closing machine 17 via a drive chain 16 installed on the shaft sprocket 15. Reference numeral 19 indicates a guide shaft through which the shutter 1 moves up and down. Reference numeral 20 denotes a belt loosening prevention device for preventing loosening of the endless belt 9, which is installed on the upper part of the support frame of the roller-equipped support 21 that supports the distance between the guide shaft 2 and the winding shaft 3; Reference numeral 22 indicates a slat loosening preventer that prevents the slats from loosening. Reference numeral 23 indicates a connector for attaching the tip of the shutter 1 to the endless adjustment belt 9.

閉鎖を助成するようになつている。 This device has the above-mentioned configuration, and to explain how to use it based on an example, a shutter is attached to the outer surface of the endless tuning band 9 that interlocks the pulleys 7 and 8 on two parallel shafts so as not to slip. Connect 1. To roll up and open this shutter 1,
The drive chain 16 is rotated by the operation of the opening/closing machine 17, and the shaft sprocket 15 installed thereon is rotated, and at the same time as this rotation, the winding shaft 3 is rotated in the lifting direction. Then, the endless tuning belt 9 meshing with the pulleys 7 and 8 also rotates, and the guide shaft 2 located above also rotates at the same time, so that the shutter 1 connected to the endless tuning belt 9 rotates. And it is rolled up on the outer periphery of the guide shaft 2 and the winding shaft 3. Next, to close the shutter 1, the opening/closing mechanism 17 is turned in the opposite direction and operates in the opposite direction. At this time, the winding spring 13 of the repulsive spring part 6 in the guide shaft 2 is wound in a repulsive state when winding up, and when the shutter 1 is pulled down in the closing direction, the restoring force is used to assist the closing due to its own weight. I'm starting to do that.

という優れた効果を有するものである。 As explained above, according to this invention, the entire device can be significantly downsized and the area can be used effectively, and the weight of the shutter itself is reduced when the shutter is fully opened, unlike the conventional elevating device for a multi-shaft shutter. Since it is placed evenly between multiple shafts, it does not become impossible to close, and has the excellent effect of being able to be opened and closed quickly and reliably.

的な効果がある。 Then, a pulley protection foil is fixed to the pulley, which is fitted and fixed from the outer periphery of the guide shaft and the winding shaft, with a gap the width of the endless tuning band, and the endless tuning band is erected. Since the upper ends are connected, both the guide shaft and the winding shaft can reliably move and rotate the endless tuning belt without detaching it, which has the effect of eliminating worries such as slipping and breakage, and improving the shutter speed. Since the construction is carried out between both shafts, the weight of the shutter is evenly applied to both shafts, which not only protects the shutter, but also protects it.
It is effective and can be used safely for a long period of time.
The adjustment band loosening prevention device installed at the top of the support with rollers takes care of loosening during shutter operation or extension of the endless adjustment band to ensure smooth sliding. effective. In addition, since the shaft sprocket provided at the end of the winding shaft is directly connected to the opening/closing machine via a drive chain, the entire winding shaft is compact and can be installed firmly. A shutter slat loosening prevention device is installed, which has a rotating part extending below the guide shaft and winding shaft, making it easy to wind up the shutter.
This has an excellent practical effect of reliably absorbing the slack of the slat during unwinding and allowing the slat to move easily at all times.
