Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blind which partially allows angle adjustment and elevation of blades.

[0002]

2. Description of the Related Art In the case of using a blind formed by stacking a plurality of conventional blades (slat) in a layered manner on a window, for example, use it to prevent sunlight from entering the room. In addition to the operation of lowering the whole and covering the window, the angle of the blade is slanted in order to finely adjust the light insertion condition. In this case, for example, when the rotary operation rod for adjusting the angle is turned, all the blades of the blind are similarly set to move diagonally. Further, when the string for raising and lowering the blind is pulled, the whole is lifted from the lower side, that is, it is only opened from the lower side. As described above, in the conventional blind, only the angle adjustment of the entire vane plate and the entire elevation can be performed.

[0003]

The conventional blind having such an operation mode has a problem that it cannot sufficiently cope with various situations in daily life. For example, if you are sitting near a window, you may want to hide the bottom half for the purpose of hiding yourself or to block light. Even in such a case, the upper half may want to raise all the blinds to take in light, or adjust the angle of the upper half blades to obtain the desired brightness. Also,
You may want to open the lower half entirely with the upper half shielded, or adjust the angle of the blades in the lower half. This is the case, for example, when you want to block the line of sight from the top when your neighbor's house has two stories. Further, there is a case in which it is desired to partially adjust the angle of the vane plates in the upper half and the lower half to partially adjust the light insertion amount. This is, for example, when it is desired to take in the light by blocking the area in the eye and adjusting the angle in the area out of the eye when the position where the light is incident is low such as in the West. It is an object of the present invention to provide a blind in which the angle of the vane plate can be partially adjusted and also the lifting operation can be partially performed.

[0004]

In order to achieve the above object, in the blind of the present invention, the blind is divided into upper and lower stages and a plurality of blade plates 4 between the head box 1 and the upper bottom rail 2 are provided. Constitutes an upper stage portion, and the lower stage portion is constituted by a plurality of blade plates 5 provided below the bottom rail 2 and the lower stage bottom rail 3 to enable the head box 1 to adjust the angle of the upper stage blade plate 4. The rotating operation means 20, the elevating operation cord 22 that enables the upper blade plate 4 to move up and down, the rotating operation means 10 that enables the angle adjustment of the lower blade plate 5, and the lower blade plate 5 to move up and down.

EXAMPLES Examples will be described with reference to the drawings. FIG. 1 is an overall perspective view showing an embodiment of the present invention. FIG. 2 is a perspective view for explaining the state of the blade plate. FIG.
It is explanatory drawing which shows the example of operation use.

An embodiment of the present invention will be described. In FIG. 1, the entire blind is attached to, for example, a window of the head box 1 by a suitable fitting not shown. The entire blind is divided into an upper stage and a lower stage. That is, a plurality of blades 4 between the head box 1 and the upper bottom rail 2 constitute an upper portion, and a plurality of blades 5 and a lower bottom rail 3 provided below the bottom rail 2 constitute a lower portion. It is configured. On the left side of the top box 1, there is provided an operation string 12 for operating the lower blade plate 5 ascending and descending, and a stopper 13
At, it is locked. Further, for example, a rotation operation rod 10 is provided as a rotation operation means for operating the angle adjustment of the lower blade plate. Similarly, on the right side of the top box, an operation cord 22 and a stopper 23 are provided for moving up and down and locking the upper blade plate 4, respectively. For adjusting the angle of the blades, for example, a rotary operation rod 20 is provided. The rotation of the rotary operation rods 10 and 20 is transmitted to a gear (not shown) in the box via the universal joints 11 and 21, and further to the rotating shaft 1 via the gear box.
The rotation is transmitted to 8 and 28. The means for rotating the gear is not limited to the rotary operation rod,
The same effect can be achieved with a string. Same rotating shaft 18,
Since one end of the ladder strings 16 and 26 is connected to 28, the angle of the blades can be adjusted by this. In addition,
The rotating shaft is supported by a suitable bearing in the top box. Furthermore, the lifting operation strings 12 and 22 are connected to the lifting strings 14 and 24 via a sliding mechanism (not shown) in the box (for example, rollers are provided to improve the movement of the strings). There is. The other end of the lifting string is fixedly connected to the bottom rails 2 and 3.

The appearance of the blade will be described with reference to FIG. The upper blade plate 4 is provided with an opening for passing the string 14 for raising and lowering the lower blade plate and an opening for passing the string 24 for raising and lowering the upper blade plate. These openings are slender holes having a sufficient length because the blades are inclined to adjust the angle of the blades, that is, the opening. Further, the upper blade 4 is provided with an elongated notch 6 facing the ladder string 16. When attempting to adjust the angle of the lower blade, as the blade becomes slanted, the interval between the ladder strings 16 becomes narrower, which interferes with the upper blade. The notch 6
Is to prevent this interference. This allows the angle of the upper blade to be adjusted independently of the situation of the lower blade. Note that the blade plate 4 is placed on a ladder cord (ladder cord) 26 and is movably supported, as in the conventional case. The lower blade 5 is provided with an opening for passing the string 14 for raising and lowering the lower blade. As in the conventional case, the blade is installed on the ladder string 16 by floating support. In the ladder string 16, there is a portion corresponding to the horizontal bar (step bar) of the ladder in the portion where the lower blade plate is provided, but the range where the upper blade plate is provided (the upper blade plate and the upper bottom plate). Between the rails), there is no portion corresponding to the horizontal bar, and it has the same shape as a normal cord.
The upper ladder string 26 is of a normal form having a horizontal bar portion. One end of the ladder string is fixedly connected to the rotating shaft, and the other end is fixedly connected to the bottom rail. Bottom rail for upper 2
It is desirable that the thickness be as thin as possible in terms of aesthetics.

The method of use will be described below with reference to FIG. FIG. 3A shows a state in which the entire blind (both upper and lower stages) has been completely lowered. The string 12 and then the string 22 are used for the operation at this time. In this state, when the lower stage is shielded or the angle is adjusted, it can be adjusted by operating the rotary operation rod 10. At the same time, the angle of the upper blades can be adjusted by operating the rotary operation rod 20. For example, when the light is coming in from a low position, such as Seisun, it is dazzling to the eyes of people in a low position, so it is desirable to shield the lower part of the blind, but to light up the entire room, you want to brighten the upper part. is there. Further, for example, it is possible to shield the upper stage and adjust the angle of the lower blade to adjust the light insertion. In everyday life, there are many times when you are worried about the line of sight from the top, such as when your neighbor's house has two stories. This is an effective way to use it. Further, for example, when it is desired to raise the upper stage to take in the light as much as possible while using the lower stage as it is for light shielding or blindfolding, the upper stage of the blind can be raised by pulling the string 22. This is the state of FIG. This is effective when you want to sit on the window and hide your body, but want to maximize the light. Even in this state, the lower stage angle adjustment can be performed by using the rotary operation rod 10. Further, the bottom rail 3 is lifted by pulling the string 12 to raise the lower stage, and the lower stage is lifted from below. This is the state of FIG. In this way, it is possible to respond by changing the operation pattern according to various situations in daily life.

FIG. 4 shows a reinforcing and guiding ring 7 provided around the notch 6. For example, it is preferably made of plastic or the like. As described above, this notch is provided for the purpose of preventing the upper blades from interfering with each other when the angle of the lower blades is to be adjusted and the ladder cords 16 have a narrow interval. . Therefore, the blade 4
Has an elongated cutout. There is a ladder string 16 facing these notches, but for the purpose of guiding so as not to separate from the notch 6 when the lower blade is raised, the blade has an elongated notch. Therefore, a ring as shown in FIG. 4 is provided for the purpose of reinforcement. The ring of FIG. 4 is designed to sandwich the blade plate, but the shape and the like are not limited to those shown in FIG. Further, when the width and strength of the vane plate are allowed, the elongated hole 8 as shown in FIG. 5 can be used.

In the above description, the upper and lower stages are two stages, but the same idea can be applied to multiple stages. This allows finer adjustments. In addition, since the blinds are often made to order, it is possible to set the ratio of the upper tier and the lower tier, that is, the number of blades at the time of ordering, according to the user's purpose of use. It can be used.

[0012]

According to the present invention, the blind is divided into upper and lower parts, and each part can be raised and lowered, and the angle of the blades can be adjusted individually. It is possible to flexibly adjust according to the situation. Since you can raise the upper half and adjust the angle while shielding the lower half, you can fine-tune the lighting. Since it is possible to adjust the lighting of the lower half while shielding the upper half, there is no need to worry about the line of sight of the next house.
