BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blind for blocking external light, and more particularly to a blind capable of blocking external light at an arbitrary position and shape of a window.

[0002]

2. Description of the Related Art Generally, it has been practiced to attach a blind to a window frame portion of a house and adjust the outside light by the blind. FIG. 1 shows such a conventional blind, which has a long mounting base 1 which is mounted on the upper portion of a window frame (not shown). Below the mounting base 1, a mounting base 1 is provided. A lower plate 2 having a length dimension substantially the same as 1 is provided. Between the mounting base 1 and the lower plate 2, a large number of blade plates 3, 3, ... Formed so as to be slightly curved in the circumferential direction in the width direction, respectively, have a predetermined distance from each other. It is arranged, the mounting base 1, each blade 3,3.
The lower plate 2 and the lower plate 2 are connected by a connecting member such as a nylon cord (not shown). In addition, an operation cord 4 made of nylon cord or the like is arranged inside the mounting base 1. The operation string 4 penetrates each of the vane plates 3, 3, ... Through a small hole through the two guide rollers 5, 5 to reach the lower plate 2, and connects the lower plate 2 up and down. Further, a stopper mechanism 6 for stopping the lower plate 2 at an appropriate position is provided, and the lower plate 2 can be held at a predetermined position by operating the winding string 4. FIG. 2 shows the mounting base 1

By operating the swing operation lever 12 to adjust each vane plate 3 to a desired angle, the outside light entering from the window frame is adjusted.

[0003]

However, in the above-mentioned conventional blind, the hoist string 4 is operated to hold the position of the lower plate 2 at a desired position, and in that state,
Since the external light is adjusted by operating the swing operation lever 12 to swing each vane plate 3, there is a difference in length and width in the range including the upper part of the window, and there is a rectangular quadrangular range. However, it can only block outside light, and it can not block only any position in the middle or lower part of the window, and can not tilt or deform the shielding range, so it has a very limited shielding function. There was a problem called. The present invention has been made in view of the above-mentioned points, and an object of the present invention is to provide a blind which is simple in mechanism and operation and can shield an arbitrary position, range and shape of a window.

[0004]

In order to achieve the above-mentioned object, the blind of the present invention has a length substantially the same as that of the mounting base 1 below a long mounting base 1 as shown in FIG. A main body base 13 is provided, and a lower plate 2 having substantially the same length is also provided below the main body base 13, and between the main body base 13 and the lower plate 2,

Small holes, etc., through which the lower plate operating string 18 penetrates to the bottom of the lower end, which are provided, are also arranged on the same vertical line so as to reduce friction during operation. The invention is characterized by providing a vertical opening / closing / horizontal swing blind with the above-mentioned structure.

[0005]

According to the vertically opening / closing / horizontal swing blind of the present invention having the above-described structure, the main body base 13 is attached to the attachment base 1, and the lower plate 2 is attached to and detached from the lower side of the window frame (not shown). The operation of the main body base operation string 15 and the lower plate operation string 18 for operation is independent and does not interfere with each other's movements, so that the operation for determining the upper end and the lower end of the shielding range can be easily performed separately. That is, first, the position of the upper end of the blind range of the blind is determined by the operation of the main body operation string 15 provided on the mounting base 1. Next, by operating the lower plate operating string 18, the lower end position of the blind shielding range is determined. Next, if desired, the body base 13 and the lower plate 2 can be manually swung to the left and right to arbitrarily determine the angle. As a final step, by operating the blade swinging mechanism 11 (not shown in FIG. 3) (shown in FIG. 2) to adjust each blade to a desired angle, the upper, middle, and lower portions of the window can be adjusted in any desired range. It is possible to block external light or adjust the amount of incident light. However, the above operation sequence is not always the same as the above. No matter where you start or where you end, you'll get satisfying results.

[0006]

The present invention will be described below with reference to the embodiments shown in the drawings. FIG. 3 shows an embodiment of the present invention. The vertical opening / closing / horizontal swing blind of this embodiment has a long base 1 for mounting which is attached to the notch portion of the window frame (not shown). A main body base 13 having substantially the same length dimension is disposed below the mounting base 1. Below the main body base 13, a lower plate 2 having substantially the same length dimension is arranged.
Between the lower plate 3 and the lower plate 3, a large number of blade plates 3, 3, ... Formed so as to be slightly curved in the circumferential direction in the width direction, are made of nylon cord or the like so as to have a predetermined distance from each other. They are connected and arranged by a connecting member (elevating string 10 in FIG. 2).

In the vicinity of both ends of the mounting base 1, a pair of guide rollers 14A, 14B for the main body operation string 15 for moving the main body 13 up and down and a lower plate operation for moving the lower plate 2 up and down. A pair of guide rollers 17A and 17B for the string 18 are provided.

A pair of main body base hanging eccentric rollers 20A, 20B are arranged near both ends in the main body base 13, and are guided by a pair of guide rollers 14A, 14B built in the mounting base 1. The main body operation string 15, which is a strip wound downwards, is mounted on one side of the bottom side of the winding, and the main body base 13 is placed with the eccentric rollers 20A and 20B as supporting points at the left and right ends. Therefore, the floating body base 13 can be tilted at an arbitrary angle with one fingertip from the brake and stabilizer functions of the eccentric roller, and can be stopped and stabilized at that position when the finger is released.

FIG. 4 shows an enlarged exploded view of the eccentric roller.
That is, although the eccentric roller on the roller shaft 16 in FIG. 4 is a rotating body, the shaft hole is eccentric, so that it cannot rotate smoothly. Turn around a little unnaturally. Since the eccentric roller of this embodiment is always biased inward in the figure, that is, in the direction of 45 degrees to the right by the tensile stress applied to the operation string, that is, the load due to the own weight of the main body base 13 and the lower plate 2, FIG. This is the most stable state in the solid line, and the most unstable in the dotted line, and it is easy to return to the solid line if left unattended.

Similarly to the main body base 13, the lower plate 2 also has guide rollers 17A, 17 incorporated in the mounting base 1.
The lower plate is guided downward from B to the lower plate 2, and the eccentric roller is used as a left and right supporting point on one side of the bottom side of the circumference of the lower plate operation string 18 of the strip around which the eccentric rollers 21A and 21B are wound. Since 2 is placed, it can be easily rocked and tilted at any angle with one fingertip, and can be stopped and stabilized at that position by releasing the finger.

As described above, since the main body base 13 and the lower plate 2 can be independently moved up and down and stopped as desired, and can be tilted by swinging left and right, the main body base 13 and the lower plate 2 are woven. It became possible to change the shielding range and the shielding form. In other words, the shape of the shielding area is not limited to the conventional right-angled quadrilateral (rectangle), but has become a unique deformed body such as a parallelogram, a trapezoid, and a triangle. The body base 13 is also provided with a set of conventional rocking devices for rocking the blade plates 3, 3, ... Shown in FIG. 2 in the circumferential direction to adjust the amount of incident light and the transmittance of the blinds. Fine adjustment is also possible.

On the other hand, in the mounting base 1, stopper rollers 22 and 23 for controlling the movement of the endless main body base operation string 15 are arranged. The stopper roller 22 passes through the inside of the mounting base 1 and is guided downward from the guide rollers 14A and 14B to wind up and down the main body base operation string 15 around which the main body base suspension eccentric rollers 20A and 20B are wound. The bundled part passes between two small rollers in a narrowed manner, and serves to release and stop the cord as necessary. Similarly, the stopper roller 23 passes through the inside of the mounting base portion 1 and is guided downward from the guide rollers 17A and 17B to penetrate the main body base portion 13 and the vane plates 3 and 3 to reach the lower plate 2. Lower plate hanging eccentric rollers 21A, 21B
The part of the lower plate operation string 18 that is wound around is bound between two small rollers, and serves to release and stop the cord as necessary.

FIG. 5 shows a state in which the upper / lower opening / closing / left / right swing blind of the present invention is fully opened. In order to obtain such a state, the main body base operation string 15 is fully pulled and the main body base 13
Is pulled up to the uppermost position, and then the lower plate operation string 18 is pulled up at the same time as described above. In this state, the appearance is the same as when the conventional blind is fully opened. This means that the blind according to the present invention is equipped with all the functions and performances of the blinds that have been used in the past, and is equipped with a new innovation. At this time, it should be noted that the main body base 13 and the lower plate 2, which are tilted by the left-right swing function, which is one of the most prominent features of the present invention, are rolled up to the fully open position without intentionally making them horizontal in advance. And all have the feature of automatically returning to the horizontal position.

FIG. 6 also shows the state where the blinds are fully opened, but unlike the case of FIG. 5, all the movable parts are gathered below, and the advantage of fully opening in this state is that the blinds can be easily cleaned. This also makes it easier to carry out repairs and inspections. In order to achieve such a state, first, the lower plate 2 should be lowered to the lowermost end, and then the main body base 13 should be lowered. Again, everything can easily be returned to the horizontal position from any tilted position. Another advantage is that when the main body base 13 descends onto the lower plate 2, a large number of blade plates 3, 3, ... It's important to keep things in order and not disturb each other.

FIG. 7 is a diagram when the valve is fully closed. The appearance is no different from conventional blinds. In this state, it is sufficient to lower the lower plate 2 to the lower end again from the fully opened state shown in FIG. It can also be achieved by pulling the main body base 13 to the uppermost end from the fully closed state shown in FIG.

FIG. 8 shows a state in which the lower half is opened.
This state can be achieved by lowering the lower plate 2 to a desired position from the time of fully opening the upper part of FIG.
FIG. 9 is a diagram in which the upper and lower parts are opened and the middle part is shielded. Although there are various ways and sequences to reproduce this state depending on the original state, it is sufficient to slightly lower the main body base 13 and slightly pull up the lower plate 2 from the fully closed state of FIG. 7. FIG. 10 shows a state in which only the upper part is opened. This state can be easily reproduced by slightly lowering the main body base portion 13 from the fully closed state in FIG. 7. The above is the operation pattern of one of the features of the present invention, that is, the "blind function for opening and closing".

Next, the operation / operation pattern of the remaining left / right swing blind function, which is another characteristic, will be described. FIG. 11 shows a state in which the lower plate 2 is rocked and tilted from the lower half opened state in FIG. 8 to slightly raise the lower end of the shielding range. This is convenient when you look out the window or when the sun is shining. Until now, blinds would not be able to do this because doing this would lead to a breakdown. FIG. 12 shows a state in which the main body base 13 is rocked and inclined from the upper half-opening of FIG. 10 so that the upper end of the shielding range is slightly inclined. In FIG. 13, the main body base 13 and the lower plate 2 are each rocked and tilted from the middle shielded state of FIG. 9 to form a parallelogram in the shielded portion. FIG.
Similarly, FIG. 4 shows a state in which the main body base 13 is swung and inclined to shield the trapezoidal portion from the intermediate shield state of FIG. FIG.
5 represents a state in which the main body base 13 is swung to the left to approximately 35 degrees and the lower plate 2 is swung to the right to approximately 35 degrees to create a triangular shielding range. FIG. 16 shows that the main body base 13 has three
It shows a state in which the lower plate 2 is swung to the right up to about 5 degrees and the lower plate 2 is swung to the left up to about 35 degrees to create a triangular shielding range. As described in detail above, the configuration and operation are extremely simple, and anyone can easily operate. Also,
The present invention newly added two distinctive features to the conventional blind, that is, the vertical opening / closing function and the swinging mechanism, so that the shielding range is limited to the horizontal part in the range including the upper part of the window like the conventional blind. It says that outside light cannot be blocked, and it cannot freely block any position in the middle or bottom of the window.
Solved many long-standing problems at once. Further, the present invention is not limited to the above-mentioned embodiments, and various modifications can be made if necessary.

[0018]

As described above, in the blind according to the present invention, the main body base 13 is brought into and out of contact with the mounting base 1 fixed to a not shown duck, and the lower plate 2 is brought into and out of contact with the lower end of the window frame not shown. Since the operations are independent, they do not interfere with each other. By holding the lower plate 2 at a desired position while holding the main body base 13 at a desired position, the blade plates 3, 3, ... Can be held at arbitrary positions of the window. External light can be blocked or the amount of incident light can be adjusted at any position of the result window. Moreover, even when the main body base 13 is vertically moved up and down and horizontally swung, the lower plate 2 can maintain the same height and angle without interference, and even when the lower plate 2 is vertically moved up and down and horizontally swung, the main body base 1
Since 3 can maintain the same height and angle without interference, the shielding range in the vertical position can be easily adjusted, and the conventional blind is fixed by the left and right swinging mechanism of the present invention. Since it is now possible to select a shielding area that does not care about maintaining the horizontal position,
In addition to the role of the blind for the purpose of simply adjusting the amount of incident light, it also has an unexpected effect that contributes to the creation of molding beauty when designing the windowsill of a building. Further, since it can be manufactured at a low cost with a simple structure, it has an advantage that it can be easily spread.
