Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a retractable blind shutter capable of tilting a slat.
[0002]
[Prior art]
Conventional blind shutters are roughly classified into two types, a folding type and a winding type. However, in the folding type, a complicated mechanism is required for the guide rail, and in the winding type, a part for tilting (tilting) the slat is incorporated in the guide rail, or after being fully opened and reversed, the tilt mode is set. There was a cause of cost increase such as complicated operation required.
[0003]
[Problems to be solved by the invention]
The present invention was devised to solve the above-described problems, and does not provide a special part on the guide rail, and the tilt is performed in a series of operations from fully open to fully closed. An object of the present invention is to provide a retractable blind shutter that does not require complicated mechanisms and operations.
[0004]
[Means for Solving the Problems]
The technical means employed by the present invention in order to achieve such a problem is a winding type having a winding shaft, a plurality of slats arranged in a vertical direction, and guide rails for guiding both longitudinal ends of the slats. In the blind shutter, an upper first shaft portion and a lower second shaft portion project from both end surfaces in the length direction of each slat, and the upper first shaft portion is supported by a suspension means. The lower second shaft portion is rotatably supported by a plurality of links that are connected to each other so as to be able to bend in the vertical direction, and an upper end portion of the suspension means and an upper end of the continuous link Each part is on the winding shaft, and the lower end of the continuous link or the seat plate at the lower end of the continuous slat is in contact with the floor surface or drainage below the opening, and the winding is when the opening is fully closed. Turn the take-up shaft in the unwinding direction Accordingly, only the hanging lifting means is coupled to drop at the opening fully closed and suspended the first shaft portion of the upper is rotated in the unwinding direction of the take-up shaft the hanging By lowering only the holding means , each slat is inclined with the lower second shaft portion as the center . Preferably, the first shaft portion is a short axis and the second shaft portion is a long axis.
[0006]
In a preferred embodiment, the plurality of links positioned above the plurality of links arranged in the vertical direction are free links that do not support the slats, and the free links are positioned above the guide rail when the opening is fully closed. The plurality of free links are configured to change from a substantially linear shape as the take-up shaft is unwound. Since the plurality of free links are not restricted by the guide rails and slats, when the winding shaft is rotated in the unwinding direction with the lower ends of the links being in contact with the floor surface, the upper free links are substantially linear. Since it bends from the appearance (in the illustrated case, it bulges in a curved shape) and only the suspension means descends, the slats tilt.
[0007]
In another preferred embodiment, a suspension base of a plurality of links arranged in a vertical direction is provided on a winding shaft so as to be freely movable in the circumferential direction, and the suspension base is unwound by unwinding of the winding shaft. It is configured to move in the direction opposite to the unwinding direction. More preferably, the suspension base is provided with a long groove extending in the circumferential direction (rotational direction) of the take-up shaft, and the suspension base is connected to the take-up shaft via a screw located in the long groove. Yes. The head of the screw is slidable in the long groove, and the suspension base is slidably provided in the circumferential direction on the winding shaft via the long groove and the screw.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings. The retractable blind shutter is preferably installed in the window opening. A shutter case 1 is provided above the window opening, guide rails 2 are provided at the left and right ends of the window opening, and a draining plate 3 is provided below the window opening. The shutter curtain of the blind shutter is configured by connecting a plurality of slats 4 up and down with a wire 6 and a continuous link 6, 60 exemplified as a suitable suspension means, and the wire 5 and the link 6, The upper end side of 60 is connected to a winding shaft 7 provided in the shutter case 1. The lowermost slat 40 constitutes a seat plate, and the slat 40 constituting the seat plate comes into contact with the draining plate 6 when the opening is fully closed.
[0009]
The slat 4 is a long material extending in the width direction of the opening, and has a gentle arc shape (a streamline like a blade of an indoor blind) in a sectional view. On the end surfaces at both ends in the length direction of the slat 4, a short axis 8 protrudes from the upper end portion of the end surface, and a long axis 9 protrudes from the lower end portion of the end surface. Further, as shown in FIG. 11, a vertical groove 4a extending downward from the upper surface is provided on the upper surface close to both ends in the length direction of the slat 4, and when the slat 4 is inclined, the vertical groove 4a becomes a guide rail. You may make it guide to the elongate guide piece 11 extended in the up-down direction by the mounted cross-sectional view L shape.
[0010]
The short shaft 8 is supported by the wire 5. Specifically, the wire 5 is provided with ring-shaped connection terminals 5a that are crimped at equal intervals. The inner diameter of the connection terminal 5a is designed to be larger than the outer diameter of the short shaft 8, the short shaft 8 is inserted through the connection terminal 5a, and a retaining ring 5b is provided on the tip side of the short shaft 8. The shaft 8 is supported by the wire 5 with some play.
[0011]
The long shaft 9 is rotatably supported by the link 6. The link 6 is a short member extending in the vertical direction, and is continuously connected to be able to bend (in other words, turnable or swingable via a turning shaft). A concave portion 6a is formed at the upper end of the link 6, and a convex portion 6b is formed at the lower end. The adjacent links are vertically moved by a rotating shaft 6c extending in the horizontal direction with the concave portion receiving the convex portion. Link. A receiving hole 6d extending in the horizontal direction is formed in the main body of the link 6, and a long shaft 9 extending from the end surface of the slat is rotatably received. In the illustrated one, the receiving hole 6d is formed at a position slightly below the central portion of the length in the vertical direction of the link. A suspension base 10 is connected to the uppermost link of the links 6 and 60 that are continuously provided in the vertical direction. The suspension base 10 has an arc surface corresponding to the circumferential direction of the outer peripheral surface of the take-up shaft 7, and abuts against the peripheral surface of the take-up shaft 7 via the arc surface and takes up via a screw 10a. It is connected to the shaft.
[0012]
A plurality of links (four in the illustrated example) above the plurality of links arranged vertically are free links 60 that do not support the slats 4 and are not restrained by the guide rails 2. Accordingly, the wire 5 is lowered, but the free link 60 is bent to absorb the rotational movement of the winding shaft 7. Since the free link 60 is positioned and bent in the shutter case 1, the bent free link 60 does not impair the aesthetic appearance.
[0013]
In the take-up type blind shutter configured as described above, the slat 4, the wire 5, and the link 6 are wound around the take-up shaft 7 by rotating the take-up shaft 7 in the take-up direction. It is stored in. When the take-up shaft 7 is rotated in the unwinding direction, the wire 5 and the link 6 are drawn out, the slat 4 descends, and the seat plate 40 comes into contact with the draining plate 3 at the lower end of the opening, thereby opening the opening. Fully closed.
[0014]
When the winding shaft 7 is further rotated in the unwinding direction (closing direction) from this state, the free block ring 60 that is located in the case 1 and is not regulated by the guide rail 2 and does not hold the slat 4 is bent. Then, only the bulging in a curved shape is performed, and the series of link 6 lowering operations is not performed. On the other hand, since the wire 5 is unwound from the winding shaft 7 and further descends, a “movement difference” occurs between the two rows of slat connecting parts (links connected to the wire 5), thereby causing the tilt of the slat 4. Is done.
[0015]
8 to 10 show other embodiments, and the same members are denoted by the same reference numerals. A long groove 100 extending in the rotation direction (circumferential direction) of the take-up shaft 7 is formed in the suspension base 10 of the continuous link, and the head of the screw 10 a passes through the long groove 100 to surround the take-up shaft 7. It is slidable in the direction. As shown in FIG. 9, when the opening is fully closed, the head of the screw 10 a is located on the proximal end side of the long groove 100. From this state, when the winding shaft 7 is rotated in the unwinding direction, the lower end of the continuous link is in contact with the draining plate 3, and the head of the screw 10 a is in the long groove 100 toward the front end side. By sliding toward each other, a “movement difference” occurs between the two rows of the slat connecting parts (links connected to the wires 5), and the slat 4 is tilted.
[0016]
The roll-up blind shutter according to the present invention is electric in one preferred example, and is preferably installed in the window opening. The vertical movement of the slat is performed by a switch (not shown), and the slat can be tilted through the fully closed state by rotating the winding shaft in the unwinding direction by a switch (not shown) to lower the slat. The slat can be tilted in a series of operations from fully open to fully closed. Further, the tilt angle may be adjusted by slightly rotating the take-up shaft, for example, with a push-off switch.
[0017]
In the present invention, the slat is tilted by the operation of the two-row connecting mechanism of the wire and the continuous link, and the structure, maintenance, and operation are simple. Since the slats, wires and links are all wound around the winding shaft, the device fits well.
[0018]
Although the wire is exemplified and described as the suspension means, the suspension means that can be employed in the present invention is not limited to the wire, and may be another string-like body, a link, or the like. Further, the take-up type blind shutter is not limited to the electric type, and can be applied to, for example, a manual type blind shutter that opens and closes by rotating a crank rod.
