Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to blinds, and in particular, it includes upper and lower horizontally fixed frames, a horizontally movable frame that can move vertically between these fixed frames, and a horizontally movable frame that can move vertically. The present invention relates to a blind that includes a blind main body disposed between the fixed frame and the movable frame, and can be opened and closed by raising and lowering the movable frame.

The present invention can be applied to conventional blinds that can be opened and closed by folding the main body of the blind into the upper part and raising and lowering it downward. This is suitable for application to a type of blind (climber type blind) that can be folded up and opened and closed by lifting and lowering it upward.

[Conventional technology]

Conventionally, in many of these types of blinds, the blind body is lowered using its own weight, and the blind body is raised using a lifting cord. In order to stop the blind body in the desired open/close position, a stopper must be provided to lock the lifting cord.

[The problem that the idea aims to solve]

The present invention aims to provide such a blind in which the blind main body can be fixed at any position without using a stopper.

[Means to solve the problem]

The present invention, as a means to solve the above-mentioned problems, consists of upper and lower horizontally fixed frames, a horizontally movable frame that can be moved up and down between these fixed frames, and one of the upper and lower fixed frames and the movable frame. In this blind, the blind body is arranged between the movable frame and the first fixed frame, which are disposed to sandwich the blind body, and which can be opened and closed by raising and lowering the movable frame. A support cord is arranged to pass through the blind body, one end of the support cord is fixed to either the movable frame or the first fixed frame via a spring, and the other end of the support cord is fixed to either the movable frame or the first fixed frame via a spring. The part is extended horizontally within the other frame, further extended vertically from one end of the frame, and then connected to a second fixed frame, or folded back from this and extended vertically to form a movable frame. At least one set of such moving frame supporting mechanisms is provided at spaced apart positions on the left and right sides of the blind main body, and the moving frame is To provide a blind characterized in that it can be fixed at any vertical position.

[Effect]

According to the present invention, the blind body can be fixed at any position without using a stopper.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.

FIG. 1 shows an embodiment of the present invention. The embodiment shown in FIG. 1 shows a type of blind that uses a bellows-shaped cloth as the blind body and opens and closes by expanding and contracting the cloth. The present invention is not limited to blinds, but can also be applied to ordinary Venetian-type blinds in which a plurality of slats are arranged vertically at equal intervals. Further, the illustrated embodiment shows a climber-type blind that is opened and closed by folding the blind body downward and raising and lowering it upward. , this can also be applied to regular blinds that move upwards and downwards. In the embodiment shown in FIG. 1, 1 is an upper horizontal fixed frame, 2 is a lower horizontal fixed frame, 3 is a horizontally movable frame that can be moved up and down between these fixed frames, and 4 is a fixed frame 2 and a movable frame. 3 shows the blind main body placed between the two.

A fixed frame 1 is fixed to the upper window frame of the window to which the blind is attached, and a fixed frame 2 is fixed to the lower window frame of the window.

The blind main body 4 is made by folding cloth into a bellows shape as described above, and is opened and closed by expanding and contracting it, and its upper edge is connected to the movable frame 3.
The lower edge of the fixing frame 2 is attached to the upper side of the fixed frame 2.

In the present invention, the support cord 6 fixed to one end of the lower fixed frame 2 via the spring 5 is extended an appropriate distance in the horizontal direction within the fixed frame 2, and then
It is taken out of the fixed frame 2 through the hole, and is extended vertically upward through the blind body 4 to move it to the movable frame 3.
introduced into the movable frame 3, stretched horizontally within the movable frame 3, led out from the end of the movable frame 3, stretched vertically upward, and fixed it to the fixed frame 1 above,
This constitutes a first moving frame support mechanism. Similarly, the support cord 6' fixed to the other end of the fixed frame 2 via the spring 5' is arranged in exactly the same manner as above, and its upper end is fixed to the fixed frame 1, and the support cord 6' is fixed to the other end of the fixed frame 2 via the spring 5'. Configure a support mechanism.

In the embodiment of FIG. 1, the blind body 4
is constructed by arranging bellows-shaped cloth members 4a, 4b, 4c horizontally and overlapping their edges, and the support cords 6, 6' are provided at the overlapped portions of these cloth members. By passing it through the hole,
These cloth members are held together in a mutually assembled condition.

In the illustrated embodiment, the upper ends of the support cords 6 and 6' are not fully fixed to the ends of the upper fixed frame 1, but are introduced into the fixed frame 1 and run inside the fixed frame 1 to the other end. It extends horizontally, extends downward from the other end of the fixed frame 1, enters the movable frame 3 again, extends slightly horizontally within the movable frame 3, extends downward again and enters the fixed frame 2, It is fixed to the end of the fixed frame 2. In this way, by arranging the support cords 6, 6', the movable frame 3 is supported double,
The moving frame will now be supported more reliably.

FIG. 2 is a front view showing a second embodiment of the present invention. In this embodiment, a support cord 6,
One end of 6' is fixed, and after extending the appropriate distance horizontally within the movable frame, it is brought out of the movable frame 3 through the hole, and is extended vertically downward through the blind body 4. introduced into the fixed frame 2, and the fixed frame 2
Stretch it horizontally within the fixed frame, guide it into the side frames 8, 8' from the end of the fixed frame, extend vertically upward within the side frames 8, 8', and vertically downward near the upper end of the side frames 8, 8'. It is fixed to the end of the fold-back moving frame 3. Reference numeral 9 denotes a motor which drives a worm wheel 12 by driving a worm attached to the shaft 10.
is rotated, and this rotation causes the cord 6 to be pulled up or down to raise or lower the blind.

As mentioned above, in the present invention, the movable frame 3 is supported by the support cords 6, 6', and these support cords 6, 6' are held under tension by the springs 5, 5'. Since the movable frame 3 is in frictional contact with the movable frame 3, the movable frame 3 is held in that position against its own weight and the weight of the blind body 4 which is fixed thereto, and the movable frame 3 is not raised or lowered. Even if the device is moved, it remains fixed in the moved position. In the figure, numeral 7 indicates a lifting cord that raises and lowers the movable frame 3, by which the blind can be opened and closed.

As described above, according to the present invention, the movable frame for opening and closing the blind is reliably held in its position by the support cord, and the blind is opened and closed by raising and lowering the movable frame. Therefore, the blind can be reliably held in the open/closed position without requiring any fixing means such as a stopper. However, unlike conventional blinds, this blind is not lowered by the weight of the lower plate of the blind and the blind body, so it can be used not only for vertical windows, but also for slanted windows or horizontal skylights. It can also be applied to The blind is also suitable for use in a climber type blind which is raised from below, as shown in the illustrated embodiment.
