Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention is to open and close a louver by suspending a louver from each of a plurality of carriers moving in the head rail by a rotation shaft provided in the head rail. And a vertical blind capable of rotating, in particular, a head rail is attached to the upper edge of a tilted window whose upper edge is inclined, and the louver is suspended obliquely from the head rail. The present invention relates to a vertical blind for a tilted window that can be opened and closed and rotated without any hindrance.

(Prior Art) Vertical blinds are widely used, and they are opened and closed by moving the carriers along the head rails, and the louver mounting shafts protruding vertically downward from each carrier are provided around the vertical shaft center. By rotating, the louver is rotated to adjust the light shielding. When attaching a vertical blind to an ordinary window, the head rail is supported almost horizontally, so that opening and closing and rotation of the louver can be performed without any hindrance, but the vertical blind is attached to an inclined window whose upper edge is inclined. When installing the louver, since the louver is suspended obliquely from the lower end of the louver mounting shaft protruding from the carrier, there is a problem in transmitting the rotation of the louver mounting shaft to the louver.

To eliminate such drawbacks, a universal joint at the bottom of the louver mounting shaft is used, for example
No. 7 or Japanese Utility Model Publication No. 2-11595.
However, in such a universal joint at the lower part of the louver mounting shaft, the structure of the louver mounting shaft becomes complicated, and a louver mounting shaft for vertical blinds for tilted windows must be manufactured.

(Problems to be Solved by the Invention) The present invention does not require any changes to the head rail of a vertical blind mounted on a normal window, a rotary shaft, a carrier, a louver mounting shaft protruding downward from the carrier, and the like. An object of the present invention is to provide a vertical blind for a tilted window in which the louver can be connected to the louver mounting shaft and the rotation of the louver mounting shaft can be transmitted to the louver without hindrance.

Conventionally, it has been attempted to fold a wire rod into an inverted U-shape and bend the tip of the wire rod upward to connect the louver mounting shaft and the louver. There is a large gap between the U-shaped part and the vertical part, so that when the blinds are opened, the connecting tools may be entangled with each other or the louver may come off.

(Means for Solving the Problem) As a means for solving the above-mentioned problems, the present invention is based on the rotation of a rotary shaft provided in a head rail attached to the upper edge of a tilted window whose upper edge is inclined. In a vertical blind for a tilted window in which a louver is hung from each of a plurality of carriers that move in the head rail and the louver can be opened / closed and rotated, at the lower end of a louver mounting shaft protruding downward from each carrier. As a connecting tool that connects the provided hook part and the louver retaining hole formed at the upper end of the louver for attaching the louver to the louver mounting shaft, bend the wire rod into an inverted U shape and move the tip end of the wire rod upward. The louver is bent in a hook shape toward the bottom and the tip is folded back to form a retaining portion, and a gap between the retaining portion and the inverted U-shaped portion is provided on the louver. By using a connecting tool having a thickness smaller than the thickness of the hook hole portion, the horizontal portion of the inverted U-shaped portion is hooked on the hook portion at the lower end of the louver mounting shaft,
Through the gap between the left and right vertical portions of the character-shaped portion and the above-mentioned retaining portion, the hooking hole of the louver is hooked to the connecting tool, whereby the louver is rotatably suspended and supported on the lower end of the louver mounting shaft. The present invention provides a vertical blind for a tilted window.

(Operation) In the above vertical blind for tilted windows, the carriers are moved along the head rails, whereby the louvers supported by the louver mounting shafts protruding vertically downward from each carrier are opened and closed. Further, by rotating the louver mounting shaft projecting from each carrier, the louvers are simultaneously rotated to control light shielding.

(Example) Hereinafter, the illustrated example will be described.

FIG. 1 shows an embodiment of a vertical blind according to the present invention, in which 1 is a head rail, 2 is a carrier which is moved along the head rail, and 3 is a downward projection from the carrier. Louver mounting shafts 4 and 4 represent louvers. In FIG. 1, the louver 4 on the left side is in a state of being at a right angle to the moving direction of the carrier, and the louver 4 on the right side is in a state of being rotated to a position parallel to the moving direction of the carrier. Reference numeral 5 denotes a tilt rod for rotating the louver mounting shaft 3 around its vertical axis. Although a screw rod for moving the carrier is not shown, it is provided in parallel with the tilt rod. Such a mechanism is exactly the same as that of a conventional vertical blind.

A hook portion 6 is provided at the lower end of the louver mounting shaft 3, and a louver hooking hole 7 is provided at the upper end of the louver. In a normal vertical blind, the louver and the louver mounting shaft are connected by hooking the louver locking hole 7 on the hook portion 6 of the louver mounting shaft 3. However, in the case of the vertical blind for tilted windows, the rotation of the louver mounting shaft 3 cannot be transmitted to the louver 4 only by hooking the hook hole 7 of the louver on the hook portion 6 of the louver mounting shaft 3.

In the present invention, as a connecting tool for connecting the hook portion 6 provided at the lower end of the louver mounting shaft 3 protruding downward from the carrier 2 and the louver retaining hole 7 formed at the upper end of the louver 4, as shown in FIG. As shown in FIG. 3, a connecting tool 8 in which a wire is bent in an inverted U shape is used. The tip of this wire is bent upward to form a hook, and the tip is folded back to form a retaining portion 9. However, the gap between the vertical portion 10 of this inverted U-shaped portion and the retaining portion 9 is made smaller than the thickness of the portion of the louver retaining hole 7 provided in the upper portion of the louver.

The horizontal portion of the connecting tool 8 is hooked on the hook portion 6 at the lower end of the louver mounting shaft 3, and the left and right vertical portions 10 of the inverted U-shaped portion are hooked.
Through the gap between the louver and the retaining portion 9
The louver 4 is attached to the louver mounting shaft 3 by engaging with the hook portion of the louver mounting shaft 3.

FIG. 3 shows the vertical blind thus assembled by attaching the louver 4 to the louver mounting shaft 3 by the connecting tool 8. In FIG. 3, 11 is a spacer cord connecting the lower part of the louver, and 12 is a weight attached to the lower end of each louver.

In the above vertical blind, the carrier 2 is moved along the head rail 1 to open / close the blind, and the louver mounting shaft 3 is rotated to rotate the louver. When the louver mounting shaft 3 is rotated, the horizontal portion of the connector 8 moves up and down in the hook portion 6 at the lower end of the louver mounting shaft 3 as seen in the right louver in FIG. Louver mounting shaft 3
Is transmitted to the louver 4. However, since the connector 8 is provided with a stopper, the louver does not come off.

(Effect of the Invention) When the blind is opened, the louver and the connecting tool for connecting the louver and the louver mounting shaft of the carrier are in such a state that adjacent louvers are in contact with each other. When the doors are closed, the connectors may catch on each other, hindering the movement of the blinds or damaging the blinds.However, with the connectors used in the present invention, the connectors do not catch on each other and the louver It is also prevented from being lifted and easily detached from the connector.

Since the hook part on the upper part of the louver is held down by the folded-back portion of the connector, the louver and the connector are fixed without rattling.
