Description

[Detailed Description of the Invention] Technical Field This invention relates to a vertical blind that is attached to a window to adjust the amount of light entering a room.

Conventional technology Conventionally, a vertical window was constructed by suspending a large number of tanzaku-shaped slats from a rail fixed to the upper frame of the window in a movable and adjustable angle relative to the window, and connecting each slat with a chain or string. In type blinds, the movement and angle of each slat can be adjusted using a control string hanging from one side of the blind, or the slats at the side end can be directly operated to interlock each slat with the chain or string. It was designed to move and adjust its angle.

However, each slat of such a vertical blind can be rotated independently with respect to the rail by a runner, and the slats are only loosely connected by the chain, etc., so it is not possible to open the window with each slat fully closed. When blocking direct sunlight from outside, each slat would sway due to the wind, making it impossible to completely block direct sunlight.

Purpose This invention was made to overcome the drawbacks of conventional vertical blinds as described above.
The purpose is to provide a vertical blind with a simple and inexpensive structure that can stably keep each slat fully closed even against disturbance factors such as wind.

Embodiment An embodiment embodying this invention will be described below with reference to the drawings. Reference numeral 1 is a rail fixed to the upper frame of the window, and a plurality of runners 2 are movably and rotatably suspended. It's lowered. A slat hanger 3 is suspended from each runner 2, and a slat 4 is suspended from the lower end thereof. Both ends of each slat hanger 3 are connected by a chain 5.

This slat hanger 3 will be explained in detail with reference to FIGS. 2 and 3. Reference numeral 6 is a hook that is formed protrudingly at the center of the upper end of the slat hanger 3, and is attached to the hanging ring 2a at the bottom of the runner 2. It is designed so that it can be hung. Reference numeral 7 denotes locking recesses provided at both upper corners of the slat hanger 3, and a protrusion 7b protruding from the opening 7a of the slat hanger 3 substantially closes the opening 7a. A locking ring 8 is fitted into this locking recess 7, and the chain 5 is locked onto this locking ring 8.

9 is a resin magnet fitted to one end of the slat hanger 3, and as shown in FIG. 3, a pair of rectangular parallelepiped magnet pieces 9a connect the connecting portion 9b.
It is integrally molded in the shape of a sandwich. and,
One end 9c of the connecting portion 9b is formed in a semicircular shape.

Reference numeral 10 denotes a fitting recess provided at one end of the slat hanger 3 for fitting the resin magnet 9 thereinto, and is the same as a stepped portion 11 provided on both sides of the side end of the slat hanger 3. It consists of a long hole 13 that opens laterally 12 within 11.
Further, the thickness of the stepped portion 11 is formed to correspond to the thickness of the connecting portion 9b, that is, the space between the two magnet pieces 9a, and the opening 12 of the elongated hole 13 protrudes oppositely above and below. A pair of locking protrusions 14
is provided.

Then, this resin magnet 9 is inserted into the fitting recess 10.
When inserted in the direction of the arrow in FIG.
The upper and lower surfaces contact the locking protrusion 14 and the fitting recess 10 is expanded vertically, and in this state, the connecting portion 9b
If this resin magnet 9 is inserted until one end 9c contacts the bottom surface 13a of the elongated hole 13, the connecting portion 9b will engage the locking protrusion 1 of the elongated hole 13, as shown in FIG.
4 and the magnet piece 9a is fitted into the stepped portion 11.

Support pieces 15 are formed to project downward from both ends of the slat hanger 3, and locking protrusions 16 are provided on the inside of the lower portions of the support pieces 15, respectively. Reference numeral 17 denotes a slat support having locking recesses 18 corresponding to the locking protrusions 16 at both ends thereof, and after the upper end of the slat 4 is inserted and supported,
By fitting this locking recess 18 into the locking protrusion 16 of the support piece 15, the slat 4 can be suspended from the slat hanger 3, as shown by chain lines in FIG.

As shown in FIG. 5, the slat hanger 3 constructed in this way is hung from the rail 1 with the resin magnets 9 alternated when the blind is open, and is suspended by the chain 5. connected. In addition, in the state shown in the figure, the obliquely opposing magnet pieces 9a of the resin magnets 9 fitted to the adjacent slat hangers 3 are attracted to each other such that one is the S pole and the other is the N pole. It is configured to have a polarity on which the force acts.

Now, in the vertical blind constructed in this way, when the slats 4 are closed from the open state shown in FIG. 5, the slats 4 at the side ends of the vertical blind become parallel to the rail 1. It rotates around runner 2 as shown in FIG.
Then, each slat hanger 3 connected to the slat hanger 3 of this slat 4 by the chain 5
are rotated in the same direction, and as shown in FIG. 6, this vertical blind becomes fully closed. At this time, the resin magnets 9 attract each other at the overlapping portions of the slat hangers 3, and the slat hangers 3 are held substantially parallel to the rail 1.

Therefore, when this vertical blind is fully closed, the resin magnets 9 fitted on the slat hanger 3 attract each other, and the slat hanger 3
Since the slats 4 can be stably held substantially parallel to the rail 1, each slat 4 will not be rotated by disturbance factors such as wind, and the function as a blind to block direct sunlight can be fully satisfied. Can be done. If the side end slats 4 are rotated in the opposite direction, each slat 4 will be rotated in the opposite direction and the blind can be returned to the open state. The slats can be closed in the opposite direction.

Further, the resin magnet 9 is integrally molded in a shape in which a pair of magnet pieces 9a are connected at a connecting portion 9b, and one end of the slat hanger 3 is fitted with a step portion 11 corresponding to the resin magnet 9 and a long hole 13. By providing the mounting recess 10 and the opposing locking protrusion 14 in the opening 12 at one end of the elongated hole 13, the resin magnet 9 can be easily and securely fitted to the slat hanger 3. Can be done.

Effects As detailed above, in this invention, the magnets 9 on one side of each slat hanger 3 attract each other no matter which direction the slats 4 are closed, so each slat 4 can be stably kept in a fully closed state. In addition, since it is only necessary to attach one magnet 9 to each slat hanger 3, the structure can be simple and inexpensive, and an excellent effect is exhibited.
