Description

[Detailed explanation of the invention] Purpose of the invention (industrial application field) This invention is installed near a window to appropriately adjust the amount of sunlight entering the room, and allows daylight to enter even when the slats are fully closed. This is about blinds.

(Prior art) Conventionally, in blinds, slats formed of opaque thin aluminum plates are suspended vertically in multiple stages using ladder cords, and the angles of each slat are adjusted in the same phase via the ladder cords using operating means. It was designed to adjust the amount of sunlight coming from outside the window.

(Problem that the invention aims to solve) However, when each slat is adjusted to an angle that allows sunlight to enter from outside the window, the interior becomes visible from outside, making it impossible to ensure privacy. If the slats were closed vertically to ensure this, there was a problem that sunlight could not be taken in.

Structure of the invention (means for solving the problems) In order to solve the above problems, this invention suspends and supports multiple stages of substantially flat slats on a ladder cord that is suspended from a head box. A desired number of stages are slats through which light can pass, and the rest are slats through which light cannot pass.

(Function) With the above configuration, the amount of light entering the room can be appropriately adjusted, and sunlight can be partially taken in even when the slats of the blind are fully closed.

(Embodiment) A first embodiment embodying this invention will be explained below with reference to FIGS. A large number of slats 4 and 5 are suspended and supported, and by operating a slat angle adjustment string 6 hanging from one side of the head box 2, the angle of each slat 4 and 5 can be adjusted in the same phase. Further, an elevating cord 7 is suspended near the angle adjustment string 6, and by operating the elevating cord 7, the bottom rail 8 can be raised and lowered, and the slats 4 and 5 can be raised and lowered.

As shown in FIGS. 1 and 2, the ladder cord 3 of the blind 1 has a slat 4 supported at about 80% of its lower side in the height direction, and a slat 5 supported at about 20% of its upper side. The slat 4 is made of a thin aluminum plate or the like that is opaque and does not allow light to pass through, as in the past.The slat 5, on the other hand, is made of a thin aluminum plate with numerous fine holes formed in the form of a mesh. It is formed into a mesh shape.

Now, when the angle of each slat 4, 5 is adjusted in the horizontal direction, such a blind 1 can take in sunlight from outside the window as needed, like a conventional blind. Even if windows 4 and 5 are tilted vertically to close completely, a portion of the sunlight can still be let in through the mesh slats 5, and the view from the front of the window can be blocked by the opaque slats 4, ensuring privacy. It is possible to let in sunlight at the same time.

Further, this invention can also be embodied in the configuration shown in FIG. That is, this blind 9 has a plurality of opaque slats 4 and a plurality of mesh slats 5 supported alternately. When the angle of each slat 4, 5 is adjusted in the horizontal direction, sunlight from outside the window can be taken in appropriately, and even when the slats 4, 5 are tilted vertically and completely closed, the mesh slats remain open. Part of the sunlight can be taken in from 5, and in this state, light-transmitting parts and non-light-transmitting parts are arranged alternately to form a horizontal striped pattern, which can express a fresh aesthetic appearance.

In this invention, instead of the mesh slat 5, a transparent or semi-transparent slat made of synthetic resin or glass that can partially transmit light may be used.

Effects of the device As detailed above, this device not only adjusts the amount of light entering the room appropriately, but also contributes to ensuring privacy by letting in sunlight from the parts that allow light to pass through even when the slats are fully closed. To provide an excellent effect of providing a blind having a fresh aesthetic appearance with a simple configuration.

Claims (1)

[Claims for Utility Model Registration] 1. Multiple stages of substantially flat slats 4, 5 are suspended and supported on a ladder cord 3 suspended from a head box 2, and light passes through a desired number of stages of the slats 4, 5.
