Abstract

PROBLEM TO BE SOLVED: To reduce a travel distance even in the installation of many blinds by applying the constitution that the operation part of a blind to be manually rolled up and down is provided at both sides of a blind body, or at both sides and intermediate part of the blind body. SOLUTION: Roller ends 111 are fixed to the body brackets 41 of the mounting surface 4 of a window, and a roller pipe 11 is rotatably journalled to the roller ends 111. Also, bevel gears 5 and 6 are provided on the jointed part of the roller pipe 11, and connected to a shaft 61. The shaft 61 of the bevel gear 6 and a transmission shaft 8 are interlocked with each other in a gear box 7. Also, a chain box 9 is provided at both sides of the roller pipe 11 and the transmission shaft 8 is passed through the box 9. The upper end of a blind 2 is fixed to the roller pipe 11, and a weight bar 3 is fixed to the lower end of the blind 2. Then, a suspended endless operation chain 10 is pulled and the roller pipe 11 is rotated, thereby rolling up and down the blind 1 from both sides, or from both sides and an intermediate part.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roll screen which can be operated on both sides or on both sides and intermediately provided with operation units for winding and lowering a roll screen for manual winding and lowering on both sides or both sides and an intermediate part of the roll screen body. It is about.

[0002]

2. Description of the Related Art The conventional manual hoisting and lowering roll screen is provided with a hoisting and lowering operation section only on either the left or right side.

[0003]

In the conventional roll screen for manual hoisting and lowering, the operating unit for hoisting and lowering is only one of right and left. Therefore, when the number of installed units is large, many operating units are required. It was necessary to operate while moving, and it took time to raise and lower the roll screen.

[0004] When the operation of winding and lowering the roll screen is completed, the next operation unit is moved to the side where the roll screen is located, and the roll screen is wound and lowered. Had the disadvantage of becoming longer.

[0005] Further, when the width of the roll screen is widened, there is a problem that a long moving distance is required for winding and lowering the roll screen for each stretch, which is inconvenient.

Therefore, it takes time and effort to raise and lower the roll screen, and the moving distance for raising and lowering the roll screen becomes longer, so that raising and lowering the roll screen becomes troublesome. There were drawbacks.

[0007] The present invention does not require any trouble in raising and lowering the roll screen for manual winding and lowering, and requires a small moving distance for raising and lowering the roll screen. The purpose is to provide a roll screen.

[0008]

SUMMARY OF THE INVENTION In order to solve this problem, the present invention is provided with an operation section for manually winding and lowering a roll screen for winding and lowering, on both sides or both sides and in the middle of the roll screen main body.

[0009]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a roll screen according to the present invention.

FIG. 1 shows a roll screen according to the present invention, which is provided with an operation section for winding and lowering on both sides when a roll screen is connected and installed, as viewed from the inside of a room, wherein the connection section is rotatable. is there. FIG. 2 is a side view of FIG. 1, FIG. 3 shows a connecting portion of FIG. 1 connected by a joint, and FIG. 4 shows an operating portion for winding and lowering the connecting portion when a roll screen is connected. Are shown.

[0011] Manual winding and lowering type roll screen 1
The main body receiving members 41, 41 rotatably rotatably support roller ends 111, 111 fitted from both sides of the connected roller pipes 11, 11 on the mounting surface 4 such as a window.
The upper end (one end) of the screen 2 is fixed to these roller pipes 11, the weight bar 3 is fixed to the lower end (other end) of the screen 2, and the screen 2 is wound up by rotating these roller pipes 11 as described later. Lower it.

As shown in FIG. 1, a roller end 1 fitted in a connecting portion of the roller pipes 11, 11 connected to each other.
A bevel gear 5 is provided between 11 and 111, and a bevel gear 6 meshing with the bevel gear 5 is provided on a shaft 61 protruding from the gear box 7. The gear box 7 is fixed to the mounting surface 4 by a gear box receiver 71. A transmission shaft 8 is provided through the gear box 7, and the shaft 61 of the bevel gear 6 and the transmission shaft 8 are linked in the gear box 7 by a worm and a worm gear (not shown).

The bevel gears 5, 6 and the gear box 7
In FIG. 1, the roller pipes 1 and 11 are provided at the central connecting portion.
It is possible to install on both sides or on either side of 1, 11.

On both sides of the connected roller pipes 11, 11, the chain boxes 9, 9 are attached to the main body receiver 41,
The transmission shaft 8 is fixedly provided at 41 and the transmission shaft 8 is penetrated into the chain boxes 9 and 9. Then, a chain wheel 81 is provided on the transmission shaft 8 in the chain boxes 9, 9. Further, the operation chain (cord) 10 is hung endlessly on each chain wheel 81 so as to hang downward from each chain box 9.

When a plurality of roll screens 1 are connected to each other, bevel gears 5 are provided on both sides or one of the roller ends 111 of the roller pipes 11, and when the gear box 7 is installed, the center of the gear box 7 is installed. A joint 12 may be provided at the connecting portion.

In the joint 12, the roller ends 111 of the roller pipes 11 are connected to each other by a joint shaft 121 such that the roller ends 111 of the roller pipes 11 are abutted. Then, the joint shaft 121 is fixed to the mounting surface 4 by the joint receiver 122.

As described above, when a plurality of roll screens 1 are connected to each other or when the width of the roll screens 1 is wide, the chain box 9 is provided in the middle of the roller pipe 11 to perform an intermediate operation. In that case, as shown in FIG. 4, the chain box 9 is fixed by the main body receiving member 41 of the roller pipe 11 bisected in the middle. Then, the same bevel gear 5 as described above is provided on one or both of the roller ends 111, 111 which are inserted into the opposed ends of the divided portion of the roller pipe 11, and the gear box 7 is provided as described above. By operating the operation chain 10 provided in the intermediate chain box 9 in the same manner as described above, both or one of the roller pipes 11 is rotated.

According to the present invention, as described above, the roll screen can be wound up and down from both sides or both sides and the middle, and when the roll screen is connected or when the width of the roll screen is wide, It can be wound up and down.

[0019]

As described above, by performing the operation on both sides, when the winding and the lowering of the roll screen are completed, the next operation unit is moved to the side where the roll screen is located, and the roll screen is moved again. There is no need to hoist or lower.
That is, the moving distance for the operation can be reduced, and the work of winding and lowering the roll screen becomes easy.

When the roll screens are connected and installed, or in the case of a wide roll screen, an operation chain as an operation unit is provided on both sides or both sides and the middle of the roll screen. Winding and lowering operations can be performed at the place using the operation chain, which improves usability.

Further, when the number of installations is large, there is no need to operate while moving a large number of operation chains, and the two roll screens can be wound up and down at one place. It is short and the work time can be completed in a short time.
