Description

[Detailed description of the invention] This invention relates to a multi-shaft shutter winding device in which a shutter winding body and a guide cylinder are installed in parallel in a shutter storage case to minimize the size of the shutter storage case. It is something.

In conventional shutter storage cases, a large number of shutters are rolled up on a single shutter roll-up cylinder, and the height of the case is extremely large, which significantly increases the overall height of the building or structure. This has the disadvantage that the building materials are uneconomical, and the ceiling height is too high, making it difficult to save energy such as heating and cooling. In addition, there are some cases in which the shutter is wound onto the winding drum using the left and right sprockets, but this method has the drawback that the shutter is more slippery than the sprocket, the shutters are not wound in parallel, and when the two are connected, The disadvantage is that the noise is very loud.

Therefore, this invention solves these conventional drawbacks by installing a shutter winding body and a guiding cylinder body for accurate winding in parallel in the storage case, and thereby making the shutter storage case It has been made significantly smaller, and the shutter has less noise.
It is designed to prevent slipping and to be pulled up stably.The main components are that the installation position of the guide guide cylinder is pivoted with a slight gap provided on the top surface of the storage case, and The outer periphery of the guiding cylinder is installed vertically above the guide rail. Therefore, according to this invention, since the winding of the shutter is pulled up vertically, it has the effect of being smooth and quiet. Furthermore, by reducing the size of the shutter storage case, the number of stairs in high-rise buildings can be increased, construction costs can be reduced, and fuel for heating and cooling can be saved.

Next, an embodiment of this invention will be described with reference to the drawings. Various thin and flat shutter storage cases 1 are mounted on a wall surface 16 such as an entrance or a window frame of a building. This storage case 1 has guide rails 5, 5 erected facing the end on the side where the shutter 4 moves up and down. Inside the storage case 1, the guide guide cylinder 3 is located vertically above the guide rails 5, 5.
An outer peripheral edge is provided, and a shutter winding body 2 is located in parallel behind it. Shafts 7, 7 provided at both ends of the winding body 2 are rotatably pivoted to bearing brackets 6, 6 located on both left and right sides of the storage case 1 through bearings 8, 8. In addition, a chain ring 9 is fixed to one of the shafts 7, and a roller chain 10 that is suspended over a transmission gear 15 of a switch 11 is meshed with the chain ring 9 in an endless manner. Next, the guide cylinder 3 has the shutter 4 rollingly joined to its outer periphery, and shafts 14, 14 at both ends are rotatably supported by bearings 13, 13 installed in the bearing bracket 6. There is. Furthermore, the guide guide cylinder 3
A plurality of buffer rings 12, 12, . . . made of soft synthetic resin are provided at predetermined intervals on the outer periphery for the purpose of noise prevention, slip prevention, and smooth rotation. Reference numeral 17 indicates the floor surface. In addition to the electric type, the shutter opening/closing device may also be a manual type or a self-closing type.

This device has the above-mentioned configuration, and to explain how to use this device based on an embodiment, first, in order to open the shutter 4, the switch 11
When the roller chain 10 is operated, the roller chain 10 is rotated via the drive transmission gear 15, and the chain ring 9 suspended therefrom is rotated. At the same time as this rotation, when the shutter winding body 2 is rotated in the pulling direction, the shutter 4 whose end is fixed to the winding body 2 rises within the guide rails 5, 5, and moves toward the guide cylinder 3. It is transferred by pressure to the buffer rings 12, 12 on the outer periphery and wound around the winding body 2. Further, when closing the shutter 4, if the switch 11 is rotated in the opposite direction, it operates in the opposite direction and pulls down the shutter 4 in the closing direction. At this time, a winding spring (not shown) in the winding body 2 or the guide cylinder 3 appropriately adjusts the repulsion to assist in opening and closing.

As explained above, according to this invention, the overall size of the device can be significantly reduced, and the height of the storage case can be significantly reduced by making the storage case of the shutter thin and flat, so that the floor height of the building can be reduced. This has a very economical effect. Furthermore, the storage case is equipped with a guide cylinder and a shutter winding body behind it horizontally in parallel, so the indoor ceiling can be kept low, making it extremely energy efficient for heating and cooling. The load of the shutter is distributed over both the guide cylinder and the winding body, allowing the use of a shaft with a smaller diameter than before, and by appropriately selecting the shaft diameter of the winding body. This has the effect of being able to adjust the outer diameter of the shutter winding body. and,
The installation position of the guiding cylinder has a slight gap on the upper surface of the storage case through which the shutter passes, so it has the effect of significantly lowering the height of the storage case. In addition, since the outer periphery of the guide cylinder is installed vertically above the guide rail, the shutter can be raised and lowered vertically without lateral vibration when the shutter is raised or lowered, so that it can be raised or lowered stably. It has an excellent practical effect without causing problems such as noise generation. Furthermore, since a plurality of soft synthetic resin buffer rings are fitted at predetermined intervals around the outer periphery of the guide cylinder, it is possible to prevent slippage between the shutter and the guide cylinder, and also to prevent noise. It also has the effect of not being damaged because it moves while buffering the air.
