JP3699422B2 - Window blind hook fixture - Google Patents

Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a hook fixture that provides a window blind with a function superior to that of a conventional window blind.
[0002]
[Prior art]
Conventional window blinds are used in the closed or open state, or the blinds up to the window or halfway. Japanese Utility Model Publication No. 55-116194 is similar to this patent, but the knob member used for it must be changed in size by the slat width, and the blind is completely raised above the window. In this case, there was a problem that a gap was generated for the length of the knob member. Furthermore, there is a hassle of using a driver function such as a 10-yen coin for mounting the knob member on the blind.
[0003]
[Problems to be solved by patents]
Currently, the use of window blinds during the day is used for the purpose of shielding or dimming the screen to prevent light from shining when using a personal computer, or blocking the room from the human eye. Was not good in terms of economy and environment, and also caused discomfort in a closed atmosphere.
[0004]
In addition, there is a method in which the lower end of the window blind is lowered to the middle position of the window for light shielding or dimming so that the field of view of the window is not blocked, but the appearance is not good.
[0005]
Therefore, with the window blinds lowered, the lower part of the blinds is closed, the room is shut off by human eyes, the upper part is open, and outdoor light can be used and outdoor scenery can be viewed. Development was desired.
[0006]
[Means for Solving the Problems]
For the above purpose, by hooking one position of the vertical support cord 2 of the blind and pulling it into the pipe, and shrinking it between one side of the two slats, This can be solved by using a hook fixture that can change the transmissivity at the bottom.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a perspective view of a window blind that can be opened and closed differently depending on the upper and lower sides of the patent application. By supporting a plurality of horizontal slats 5 at a constant interval in the vertical direction by the vertical ladder-shaped support cord 2, and moving the front vertical portion and the rear vertical portion of the support cord 2 relatively up and down, When the hook fixing device of the patent application is attached to the B-1 point and B-2 point of the vertical support cord 2 to the window blind which is adjusted to block the light by moving the slat 3, the point B-1 And the point of B-2, the angle of the slat 3 changes and the difference in the transmissivity appears. By changing the angle of the head box 1 by the operation of the original method, the lower part of the blind is closed, the external field of view is blocked, and the upper part is opened to allow sunlight. Further, by changing the angle of the head box 1 in the opposite direction, the upper part is closed to prevent the incidence of sunlight, and the lower part is opened to be seen outside.
[0008]
FIG. 2 is a side view of the blind. By keeping the head box 1 horizontal and tightening a part of the vertical support cord 2-1 like A, the front edge of the upper and lower slats close to point A are in close contact with each other, and the upper part remains open. The lower part is in a closed state, the upper part has a maximum light transmittance, and the lower part is in a state of reduced light transmittance.
[0009]
FIG. 3 is a side view of the blind. While the head box 1 is tilted, a part of the vertical support cord 2-1 is tightened like A so that the front side edges of the upper and lower slats close to the point A are in close contact with each other and the lower part is left open. The upper part is in a closed state, the lower part has the maximum light transmittance, and the upper part is in a state of reduced light transmittance.
[0010]
FIG. 4 is a side view of the blind. With the head box 1 tilted, the vertical support "cord 2-1 is tightened as two adjacent points A-1 and A-2, and the upper and lower slats adjacent to the points A-1 and A-2. If the front edges of the three are brought into close contact with each other and the lower part is left open, the upper part becomes more prominent and the light transmission at the upper part can be reduced to near zero.
[0011]
FIG. 5 is a perspective view of the hook fixture C of the patent application. At the tip of the hook 6, the vertical support cord 2 is pulled into the pipe 7 while holding the beads 8 for easily pulling the hook 6, and is displaced by the knurled screw 9. Tighten the hook 6 at any position that suits the purpose. At this time, the beads 8 may be circular, square or looped. The pipe 7 may be cylindrical, elliptical or rectangular and is threaded. The knurled screw 9 may be an ordinary screw.
[0012]
FIG. 6 is a perspective view of the hook fixture D of the patent application. Put the vertical support cord 2 at the tip of the hook 6 while holding the bead 8 for pulling the hook 6 into the pipe 7, drill a hole in the tip of the screw 12, pass the hook 6, and attach the knurled nut 10. The hook 6 is tightened at an arbitrary position suitable for the purpose so as not to be displaced by the knurled nut 10. At this time, the beads 8 may be circular, rectangular or looped. The pipe may be cylindrical, elliptical or rectangular, and a hole is made in it. The knurled nut 10 may be an ordinary nut.
[0013]
FIG. 7 is a flowchart of the usage of the hook fixture. A hook 6 is hooked on the vertical support cord 2 between any two slats 3 in the blind, and is pulled into the pipe 7 so that the distance on one side of the slat 3 is shortened. Then, a knurled screw 9 in FIG. 5 or a knurled nut 10 and a screw 11 in FIG. 6 are joined together, or an elastic body such as rubber is attached to the inner wall of the pipe 7 and held by the resistance force of the hook 6.
[0014]
FIG. 8 shows an outline view of the hook fixture E and a flowchart of its use. (1) Hook the U-shaped hook 13 on the vertical support cord 2 between any two slats in the blind. (2) Pull the pipe 7 into the pipe 7 so that the distance on one side of the slat 3 is shortened. At this time, the U-shaped hook 13 can be held by a rough surface, or a frictional force resistance between the rough surface and the rough surface of the pipe inner wall, the rough surface, or an elastic body such as rubber. (3) In this case, if the U-shaped hook 13 and the pipe 7 are resinous objects such as rubber and plastic, the U-shaped hook 13 and the pipe 7 are not cut while keeping the pulled vertical support cord 2 from being cut. You can cut it short. (4) Furthermore, in order to improve the beauty, a color bowl 14, a colored sheet, or a patterned sheet can be attached.
[0015]
【The invention's effect】
With the blinds down to the bottom of the window, the slat 3 at the bottom of the shrunken vertical support cord 2 is closed, and the screen does not shine when the computer is used. The room is cut off from the human eye, the outside is open and the outside scenery can be seen, and the outside light can be used to reduce the lighting cost. As a result, it helps to solve environmental and energy problems.
[0016]
Also, the transmittance of the upper and lower parts can be changed by moving the transmittance adjustment tool in the blind head box 1, the lower part is closed, the upper part is open, the lower part is opened, the upper part is opened. A closed state can be created to block strong external light from above the window, and soft light can be taken into the room below.
[0017]
Further, even when the operation cord 5 in the blind head box 1 is moved, the difference in the translucency is maintained. Also, there is no problem with the published Shinsho 55-116194.
[0018]
The patent application is also applicable to blinds already installed indoors in order to partially change the light transmission.
