Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a shutter-type blind installed on the opening surface of a building, and particularly to a device for adjusting the inclination angle of the slats (IPC: E06B).

(Prior Art) Conventionally, slit-shaped guide rails for vertically guiding a blind body consisting of a large number of slats are formed on opposing surfaces of left and right guide frames, and A shutter blind is known in which one winding string and two slat inclination angle adjusting strings are housed in a frame (for example, see Japanese Patent Laid-Open No. 57-85484).

(Purpose of the invention) The present invention relates to a shutter blind characterized in that a pair of parallel guide means for guiding each slat is provided on at least one of the left and right guide frames, and It is an object of the present invention to provide a shutter blind in which the inclination angle of each slat can be adjusted by changing the relative spacing.

(Structure of the invention) That is, the present invention consists of a blind main body consisting of a number of slats connected in series that move up and down guided by guide means provided along the opening surface of a structure, and a drive for opening and closing the blind main body. In the shutter blind slat inclination angle adjusting device, the guide means includes a first guide rail provided on at least one of the left and right guide frames and a second guide rail parallel thereto. including,
One of the guide rails is a fixed guide rail, and the other is a movable guide rail that moves parallel to the guide rail, and each of the slats extends outward in the longitudinal direction of the slat from a side end of the slat in a crank shape. a first guide shaft and a second guide shaft that are parallel to each other; the first guide shaft is rotatably and slidably guided by a second guide rail;
The guide shaft is rotatably and slidably guided by the second guide rail. Hereinafter, the present invention will be described in detail according to embodiments shown in the drawings.

(Embodiment) In the illustrated embodiment, reference numeral 1 denotes a pair of left and right guide frames (see FIG. 4) fixed on both sides of an opening in a building, and guide means (to be described later) provided on each of the pair of guide frames 1. , the shutter taboo line main body A moves up and down in the vertical direction. In addition, connect the slats that are vertically adjacent to each other with 1 piece of connecting tape.
The shutter blind body A, which is connected in a series through a plurality of shutter blind bodies A, and the winding drum 16, which drives the shutter blind body up and down in the vertical direction through a winding tape 15, are constructed using conventionally known blind shutters. It is no different from the one in . Reference numeral 2 designates individual slats constituting the shutter blind main body, and a rotation center shaft 3 as the first guide shaft is provided at the left and right end portions of each slat, and a second guide shaft is provided outside of the rotation center shaft 3 as the first guide shaft. A crank arm 4 having a crankshaft 5 is integrally formed. In this embodiment, the guide means includes a fixed guide rail;
It consists of a movable guide rail that moves while maintaining a parallel state to the fixed guide rail. That is,
Reference numeral 6 denotes a vertical groove serving as a fixed guide rail formed on the opposing surfaces of the left and right guide frames 1, and the rotation center shaft 3 of the slat 2 engages with the vertical groove. Reference numeral 7 denotes a moving guide rail having a U-shaped cross section and provided at a corresponding position within each guide frame so as to be movable in parallel with the vertical groove, and its upper and lower ends are as follows:
A central axis 12,1 is located within a plane that includes the pair of vertical grooves.
The crankshaft 5 of the slat slides on the movable rail. Engage freely. The central axes 12 and 13 of the pair of discs are supported by the guide frame, and the pair of discs is moved within a range of 45 degrees left and right with respect to the center line of the vertical groove using the moving rail as a connecting rod. Rotating synchronously, the moving rail moves parallel to the vertical groove 6. Therefore, with each crank arm 4 integral with the slat 2 forming an angle of inclination equal to that of the supporting arms 10 and 11 of the pair of upper and lower discs 8 and 9,
The shutter blind main body A can slide vertically while being guided by the vertical grooves 6 and the moving rails 7.

By the way, in this embodiment, the slat can be tilted only when the shutter blind main body A is at the lower limit stop position. That is, one end of the winding tape 15 is tied to the lower end of the shutter blind main body A, which is connected in series by the connecting tape 14 of a predetermined length for holding adjacent slats 2 at equal intervals. , the other end of the winding tape is fixed to the winding drum 16. A disc 17 for adjusting the inclination angle of the slat is coaxially provided adjacent to the winding drum, and the disc for adjusting the inclination angle is connected to the shutter blind main body A via a clutch means (not shown). In the state in which the winding drum 16 has been lowered to the lower limit stop position, it is combined with the winding drum 16 and rotates together. Further, the inclination angle adjusting disk and the pair of disks 8,
9 is connected with a connecting rod 18, and rotates in synchronization.
And the lock pin 1 is on the bottom crank arm 4.
9 is provided, and constitutes a temporary lock together with a lock receiver 20 fixed to the guide frame side. Therefore, after lowering the shutter blind main body A to the lower limit stop position, by further rotating the winding drum 16 by 90 degrees in the unwinding direction, each slat can be changed from a horizontally open state to a vertically closed state. In this state, the shutter blind main body A can be locked.

In addition, in the embodiment described above, the moving rail 7
A disc 17 for adjusting the slat angle by extending the upper end of the
By connecting with the connecting rod 18, the connecting rod 18 can be omitted. In this case, the upper disks 8, 9 can also be omitted. Furthermore, in this embodiment, the winding drum and the disk for adjusting the slat inclination angle are interlocked via the clutch, since the inclination angle of the slat can also be adjusted by the operating means of the winding drum. Therefore, it goes without saying that if an operating means for adjusting the slat inclination angle is provided separately, the slat inclination angle can be adjusted regardless of the elevational state of the shutter blind main body.

(Effects of the invention) Since the present invention is constructed as described above, a shutter blind with a novel structure that does not use strings can always hold a large number of slats with their inclination angles aligned. A tilt angle adjustment device can be provided.
