Vertical blinds

Abstract

This provides a vertical blind that prevents adjacent strip-shaped sheets from becoming entangled. [Solution] The strip-shaped sheet 4 of the vertical blind 2 and the lower end portions of adjacent strip-shaped sheets 4 are connected by a pair of connecting cords 6. The vertical blind 2 also has an opening 8 in the center of the lower end portion of the strip-shaped sheet 4, and a through cord 10 is passed through the opening 8 and through multiple strip-shaped sheets 4.

Description

Technical Field

[0001] The present invention relates to a vertical blind in which a plurality of strip-shaped sheets are arranged side by side vertically.

Background Art

[0002] Vertical blinds are generally used as blinds for blocking or admitting light. In a vertical blind, a plurality of strip-shaped sheets are arranged side by side vertically, and both sides of the lower end side portion of the strip-shaped sheet adjacent to the strip-shaped sheet are connected by a pair of connecting strings (see, for example, Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, when opening a window glass or a door to take in outside air, the strip-shaped sheets of the vertical blind may sway due to the wind, and the adjacent strip-shaped sheets may become entangled with each other. In such a case, there is a problem that the side-by-side arrangement of the strip-shaped sheets cannot be maintained.

[0005] An object of the present invention is to provide a vertical blind in which entanglement between adjacent strip-shaped sheets is suppressed.

Means for Solving the Problems

[0006] According to the present invention, there is provided the following vertical blind for solving the above problems. That is, "A vertical blind in which a plurality of strip-shaped sheets are arranged side by side vertically, both sides of the lower end side portion of the strip-shaped sheet adjacent to the strip-shaped sheet are connected by a pair of connecting strings, A vertical blind is provided, which has an opening in the center of the lower end portion of a strip-shaped sheet, through which a through cord is passed and through multiple strip-shaped sheets. [Effects of the Invention]

[0007] The vertical blind of the present invention is A vertical blind in which multiple strip-shaped sheets are arranged vertically, The lower end portions of the strip-shaped sheets and the adjacent strip-shaped sheets are connected on both sides by a pair of connecting strings. An opening is provided in the center of the lower end portion of the strip-shaped sheet, and a through-string is passed through this opening and through multiple strip-shaped sheets. Therefore, even if the strip-shaped sheets shake, the through-string passing through the central opening prevents adjacent strip-shaped sheets from becoming entangled. Thus, the problem of being unable to maintain the adjacent arrangement of the strip-shaped sheets is resolved. [Brief explanation of the drawing]

[0008] [Figure 1] A perspective view of the lower end portion of the vertical blind according to the present invention. [Modes for carrying out the invention]

[0009] Hereinafter, preferred embodiments of the vertical blind according to the present invention will be described with reference to the drawings.

[0010] As shown in Figure 1, in the vertical blind 2, multiple strip-shaped sheets 4 are arranged vertically (up and down). The material of the strip-shaped sheets 4 may be a known material such as synthetic resin, synthetic fiber, metal, or wood. Although not shown, the upper part of each strip-shaped sheet 4 is supported by a rail member via an appropriate support member so as to be slidable and rotatable. The rail member is installed along the top of the frame of the opening in the building (for example, a window frame).

[0011] The lower end portions of the strip-shaped sheet 4 and the adjacent strip-shaped sheet 4 are connected on both sides by a pair of connecting strings 6. The connecting strings 6 can be made from a suitable material such as synthetic resin, synthetic fiber, or metal. In this embodiment, the connecting strings 6 are located at the lower end of the strip-shaped sheet 4, but they may be located slightly above the lower end of the strip-shaped sheet 4. In other words, the connecting strings 6 do not need to be located at the lower end of the strip-shaped sheet 4 as long as they can connect the lower end portions of the adjacent strip-shaped sheet 4. Although not shown, openings for passing the connecting strings 6 may be formed on both sides of the lower end portion of the strip-shaped sheet 4, or ring-shaped members for passing the connecting strings 6 may be attached. The upper end portions of the strip-shaped sheet 4 and the adjacent strip-shaped sheet 4 may also be connected on both sides by a pair of upper connecting strings (not shown).

[0012] A circular opening 8 is formed in the center of the lower end portion of the strip-shaped sheet 4, and a through-string 10 passes through the opening 8. That is, the through-string 10 passes through each of the multiple strip-shaped sheets 4. The through-string 10 can be made from a suitable material such as synthetic resin, synthetic fiber, or metal. As shown in Figure 1, a retaining portion 10a, which is not large enough to pass through the opening 8, is formed at the end of the through-string 10 in this embodiment, and this retaining portion 10a prevents the through-string 10 from falling out of the opening 8 of the strip-shaped sheet 4. The retaining portion 10a can be formed by tying a knot after passing the through-string 10 through the opening 8. Alternatively, a retaining piece (not shown) that is not large enough to pass through the opening 8 may be attached to the end of the through-string 10 as the retaining portion 10a.

[0013] Furthermore, in the vertical blind 2 of this embodiment, the through-cord 10 is passed through each strip-shaped sheet 4, so that the relative positions of adjacent strip-shaped sheets 4 do not shift significantly. Therefore, when opening an opening such as a window on which the vertical blind 2 is installed is opened to let in outside air, the strip-shaped sheets 4 are prevented from swaying in the wind and becoming entangled with adjacent strip-shaped sheets 4.

[0014] As described above, in the illustrated embodiment of the vertical blind 2, both sides of the lower end portion of the strip-shaped sheet 4 and the adjacent strip-shaped sheet 4 are connected by a pair of connecting cords 6, and an opening 8 is provided in the center of the lower end portion of the strip-shaped sheet 4, and multiple strip-shaped sheets 4 are passed through the opening 8 by passing through cords 10. Therefore, even if the strip-shaped sheets 4 sway, the passing cords 10 that pass through the central opening 8 prevent adjacent strip-shaped sheets 4 from becoming entangled with each other. Thus, the problem of not being able to maintain the adjacent arrangement of the strip-shaped sheets 4 is resolved. [Explanation of Symbols]
