Abstract

PROBLEM TO BE SOLVED: To make a natural illumination function compatible with a ventilation function by a method wherein suspension strings are inserted through each of a plurality of chevron blades, which are aligned in parallel, and both the two ends of the suspension string are respectively tied to upper and bottom frames in parallel to the chevron blades. SOLUTION: Lock nodes 12 are formed at equal intervals at a pitch equal to the height of a chevron blade 1 on suspension strings 7 tied on upper and bottom frames 4 and 5 and the chevron blade 1 is nipped between the nodes and suspended by hook tools 13. A potbellied lock hole 2 is formed in the apex of the chevron blade 1. When the so-formed chevron blades 1 are assembled together, the suspension string having the lock node 12 is first inserted in the larger hole of the lock holes 2 and then the suspension string 7 is transferred to the chevron blade having the smaller hole and locked by the lock node 12. When a value of a pitch is set to a value approximately equal to the height of the blade, direct sunlight about to pass through the two chevron blades is shielded at all angles and a closing state is produced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blind or a blind for the purpose of shielding the sunlight coming in through a window of a general building or shielding it from the outside eyes.
Specifically, it relates to the blinds with the Yamagata blade.

[0002]

2. Description of the Related Art FIG. 1 shows a front view of a blind, which is conventionally commercially available. FIG. 2 shows a side view of FIG. The blind is hung by the window using hook 1. Horizontal frame 5 made of bamboo, reed stalks, or plastic tubes between the frames 2 and 3.
However, it is woven with vertical string 4. Since such a conventional blind has a structure in which the horizontal bones 5 are densely arranged, it has a large light-shielding effect, but the interior of the room becomes dark because the amount of incident light cannot be adjusted, and the ventilation is poor. It was inconvenient and difficult to store. FIG. 3 is a front view of a blind, which is a type of conventional blind, and FIG. 4 is a side view thereof. A plurality of blades 9 are held between the frames 7 and 8 by a hanging string 10. It is hung by the hook 6 near the window. The handle 11 is for changing the inclination angle of the blade 9. FIG. 4A shows that the blade 9 is in a horizontal state,
Similarly, (B) shows the state of upward inclination, and (C) shows the state of downward. (A) is for when you want to improve ventilation or visibility, (B) is for promoting lighting, (C)
Indicates a state in which adjustment is performed when it is desired to block light or blindfold. As described above, the conventional blind has the function of satisfying each of the necessary requirements, but at the same time has the drawback of not satisfying the requirement. For example, in (A), the inside of the room can be seen well from the outside in the lateral direction, and in (B) and (C), ventilation is obstructed and it is difficult to blind from the oblique direction. Generally, there is a problem that the interior can be seen well from the outside due to indoor lighting at night, and in particular, such a problem is exacerbated in a house in a densely packed area, a high-rise house, and a general house in the vicinity thereof. In this case, in the conventional blinds and blinds, it was necessary to select whether to prioritize ventilation or blinds. Further, such problems are exacerbated in high-rise houses and general houses in the vicinity thereof, which are completely shaded and blindfolded. In this case,
In conventional blinds and blinds, it was necessary to choose whether to prioritize ventilation or blindfold. In addition, when the blade is set up to completely block light or blindfold, there is a drawback that the blade shifts due to wind and the entire blind sways due to wind pressure, and conventional blinds and blinds are structurally It was not possible to procure and assemble the necessary parts by one that fits the size of the room and the interior of the room, and there was the inconvenience of having to endure with a high price and halfway size. .

[0003]

In order to achieve the above object, the angled blade of the present invention is provided with a plurality of angled blades provided with a plurality of locking holes, and the angled blades are separately provided in the corresponding locking holes A respectively. Through the hanging string of the lock hole A
It is locked by a node provided on the hanging string above and arranged parallel to each other, and both ends of the hanging string are connected to the upper frame and the bottom frame so as to be parallel to the chevron blade, and the upper part It consists of a chevron blade and a bottom frame suspended from the frame.

Further, in the above-mentioned blind, in order to adjust the lighting by changing the interval between the chevron blades, the hanging string is made of an elastic body, the tension bar is fixed on the upper frame, and the lock is slid vertically. A stopper may be provided on the tension bar.

In the above-mentioned blind, a plurality of loose holes are provided on the chevron blade in order to perform the raising operation of the blade and the adjusting operation of the lighting by one operation cord, and one end of which is connected to the bottom frame. The other end of the lifting cord is separately passed through corresponding loose holes and pulleys provided on the upper frame, and a plurality of spring bodies acting outward from the opening of the chevron section are mounted on the chevron blade. It can also be configured.

Further, in order to adjust the lighting by changing the gap between the angled blades arranged in parallel, the angled blades provided with a plurality of locking holes and the angled blades provided with a plurality of loose holes are separated from each other. In separate blade opening and closing strings arranged so as to have an arbitrary integral multiple of P and provided with nodes at intervals of the pitch P, one end thereof is connected to the bottom frame, and the other end is a corresponding locking hole of the chevron blade or The loose hole and the pulley provided on the upper frame may be separately provided. Here, the loose hole is a hole having a size larger than that of the node provided on the blade opening / closing string.

In addition, in order to adjust the lighting by changing the height of the chevron blades, in a plurality of butterfly chevron blades that are butterfly-operated at the apex of the chevron cross section by external force, the crest and left and right end portions of the same cross section are provided. Provide a plurality of lifting lifting straps consisting of a blade opening and closing strap and a blade hanging strap to hold each, one end of the blade opening and closing strap is tied to the upper frame, one end of the blade hanging strap is passed through a pulley provided in the upper frame, The butterfly angle blades may be arranged in parallel and suspended from the upper frame.

Further, in the comb-shaped blade according to the present invention, the mountain-shaped blade having a plurality of locking holes and the mountain-shaped blade having a plurality of loose holes are arranged so that the distance between them is an arbitrary integer multiple of P. Then, separate blade opening / closing strings provided with nodes at intervals of the pitch P are individually passed through corresponding locking holes or loose holes and pulleys provided on the upper frame, and have locking holes at the bottom. The angled blades are connected to the bottom frame or side frames with springs, both ends of the top frame and the bottom frame are abutted and fixed to the left and right side frames, and the ends of the angled blades that have locking holes on the left and right side frames. The outer frame can be provided by supporting the parts so as to slide in the vertical direction.

Further, in the case of the blind using the angled blade with the outer frame, the upper frame and the bottom movable angled blade are supported so that both ends thereof slide in the vertical direction, and separate blades provided with nodes at intervals of the pitch p. The opening and closing cords are individually passed through a plurality of loose holes B provided on the fixed chevron blade, locking holes B provided at corresponding positions on the movable chevron blade, and pulleys provided on the upper frame, and the movable rope is at the bottom. It is also possible to connect the chevron blades to the outer frame with springs and to support the ends of the movable chevron blades on the left and right side frames so as to slide vertically.

[0010]

The angled blades of the present invention are generally used by suspending them at the window, and each angled blade is suspended by passing a suspending cord at the apex portion of its cross section.
Of two adjacent chevron blades hung side by side in parallel in the same direction, the apex of the lower chevron blade is arranged so that it exists on the straight line connecting the left and right edges of the chevron cross section of the upper chevron blade, Direct light that tries to pass between these two chevron blades is blocked at all angles. In this state where the chevron blades are closed, even in this case, the passage area of the air passing between the two chevron blades is almost half that in the case where there are no chevron blades. Similarly, the passing direction of the air flowing in the horizontal direction is changed to a different degree depending on the height of the chevron blade. From this closed state, if these two chevron blades are adjusted so that the distance between them becomes large, the light can be taken according to the size of the distance. However, even in this case, the incident light from the oblique direction is obstructed by the chevron blade, and the tendency becomes more remarkable as the incident angle increases.

When the sling for suspending the chevron blades is made of an elastic material and the bottom frame is pulled down, the intervals of the chevron blades are extended substantially uniformly. When the bottom frame is locked on the stopper, the distance between the chevron blades corresponding to the locking position of the stopper is maintained.

When the lifting cord connected to the bottom frame is pulled up through the pulley on the upper frame, the lifting cord does not directly move the chevron blade having the loose hole, but the bottom frame is pulled up. The chevron blades placed on the frame are sequentially pulled up. At this time, a certain angled blade is lifted upward without the angled blades overlapping with each other due to the repulsive force of the spring body when the apex of the angled blade immediately below the spring body attached thereto contacts. The chain is chained upwards so that it contacts the spring body of the chevron blade. Continue pulling the lifting cord until it spreads to all Yamagata blades,
The mountain blades are all supported by the spring body.
This state is the state where the blade is closed. In this case, the spring constant of the spring body attached to a certain angle blade is
Set it in consideration of the allowable amount of deflection with respect to the weight received from the mountain blade immediately above. When the lifting cord is pulled further from this state, the spring body is deformed to such an extent that the mountain-shaped blades overlap with each other, and finally all the mountain-shaped blades overlap. This is the state where the blade is pulled up.

Since the chevron blade is only locked by the node on the hanging string, it can freely move up and down on the hanging string until it contacts the node immediately above in the upward direction. Among the chevron blades having the locking holes and the chevron blades having the loose holes, only the chevron blades having the locking holes are pulled up by the blade opening and closing cord through the blade opening and closing cord. Then, pitch P
If there is another chevron blade in the raised position, they will overlap. As a result, in the presence of the two chevron blades, a space for approximately one chevron blade is created. This means that, for example, when looking through a blind, the effect is almost the same as when the distance between two adjacent chevron blades is increased by one chevron blade. The angled blade pulled up by the blade opening / closing string can be lowered by utilizing the weight of the bottom frame and the weight of the angled blade.

The butterfly mountain-shaped blade suspended from the upper frame and clamped at both ends by the blade suspension cord and fixed in the vertical position is moved up and down by a certain distance by the blade opening / closing cord also retaining the top thereof. Thus, the height of each butterfly chevron blade can be adjusted, and the minimum height can be reduced to the thickness when the butterfly chevron blade is flat.

When the blind according to the present invention has a structure with an outer frame, it can be freely moved left and right like a sliding door. Further, among the mountain-shaped blades having the locking holes, if the outermost frame is connected to the lowermost one of the mountain-shaped blades, the mountain-shaped blade pulled up by the blade opening / closing string is pulled down by its elasticity.

When arranged in the same manner, that is, the value of pitch P is
If it is set to be approximately equal to the height H of the
Direct light that tries to pass between these two angle blades
Is shaded at all angles. This closes the Yamagata blade
It is in a state of being set to, and even in this case, these two chevron shapes
The passage area of the air passing between the raids is almost restricted.
Secured without. Also, the flow direction of the passing air
Changes depending on the cross-sectional shape of the chevron blade and the height H.
The degree of change will change, and the greater the degree of change, the more air will pass.
The resistance increases. From this closed state, if the distance between these two angled blades is adjusted to be large, the light can be taken according to the size of the distance. However, even in this case, the incident light from the oblique direction is obstructed by the chevron blade, and the tendency becomes more remarkable as the incident angle increases.

When the hanging string for suspending the chevron blades is made of an elastic body and the bottom frame is pulled down, the intervals of the chevron blades are extended substantially uniformly. When the bottom frame is locked on the stopper, the distance between the chevron blades corresponding to the locking position of the stopper is maintained .

When the lifting cord connected to the bottom frame is pulled up through the pulley on the upper frame, the lifting cord does not directly move the chevron blade having the loose hole, but the bottom frame is pulled up. The chevron blades placed on the frame are sequentially pulled up. At this time, when a certain mountain-shaped blade is attached to the top of the mountain-shaped blade immediately below, the mountain-shaped blades are lifted up without being overlapped by the repulsive force of the spring-body, and further above it. The chain is moved upward in sequence so that it comes into contact with the spring body of the chevron blade. If you continue to pull the lifting string until it reaches all the angle blades, all the angle blades will be supported by the spring body. This state is the state where the blade is closed.
In this case, the spring constant of the spring member mounted on the chevron blades there is to pair the weight received from the immediately Yamagata blade above
Set in consideration of the allowable amount of spring body deflection. From this state, when further pulling the lifting cord, the spring member is deformed enough to Yamagata blade overlap each other, have if eventually overlap all chevron blade, the overall length is compressed. This is the state where the blade is pulled up.

[0013] Yamagata blade, suspended since on straps Kakaritomebushi only is supported from below, until in contact with the immediately above Kakaritomebushi freely move up and down on the sling. Also, among the angled blades that passed through the blade opening and closing cord, there is a locking hole .
Only chevron blades is pulled by the blade closing straps, the chevron blade having a loose bore Tomah to the original position
You. The angled blade in the locking hole was pulled up by the distance P
If there is another chevron blade in that position,
Since they overlap each other and a gap is created accordingly, lighting, ventilation, or
You can improve your outlook. The angled blade pulled up by the blade opening / closing string can be lowered by utilizing the weight of the bottom frame and the weight of the angled blade.

Also, a butterfly attached to the upper frame
Mount the angle-shaped blade that is lie-operated to the blade suspension string at both ends.
The height of each chevron blade can be adjusted by holding it and moving the top part up and down by a certain distance with the braid opening and closing cord that is also held, and the minimum height is the chevron shape.
When the blade becomes flat, it is almost
It will be about the thickness.

[0025]

Since the present invention is configured as described above, the following effects can be obtained.

The interlock by the angled blade of claim 1 is
Since the chevron-shaped blades are arranged in parallel in the vertical direction, the light-shielding effect from an oblique direction is extremely large, and almost complete shading is possible with the chevron-shaped blades closed. Further, the ventilation effect is excellent, and even if the wind blows, the blind body and the blade itself are less likely to shake. Therefore, it is expected to exert great power not only for the purpose of shading, but also for the purpose of blindfolding for protecting privacy, especially for protecting privacy related to high-rise buildings.
For example, it is most suitable for use in bathrooms and toilets that require both ventilation and blindfolding. Furthermore, the individual parts have a simple structure that can be easily assembled, so that the user can purchase the necessary parts according to the application and taste and assemble them by himself. It can also be a product. In addition, it is possible to hang the angled blades on the hanging string provided with the locking nodes at intervals of the pitch P at equal intervals without any gaps, or to make a blank without the angled blades depending on the location to illuminate or ventilate. Can be adjusted to encourage

In the blind using the angled blade according to the second aspect, the degree of opening and closing of the blade can be steplessly changed by a simple operation to adjust the visibility through the blind, ventilation and lighting.

In the comb with the chevron blade of the third aspect, both the opening and closing and the lifting of the blade can be performed by operating one lifting cord.

In the blind using the angled blade according to the fourth aspect, the opening and closing degree of the blade can be changed by a simple operation of pulling and returning the blade opening and closing cord to adjust the visibility through the blind, ventilation and light shielding. it can. Further, since the vertical length of the blind according to the present invention is substantially constant, it can be neatly housed in the window frame and mounted. Further, by selecting a chevron blade having a locking hole or a chevron blade having a loose hole, the blade opening / closing cord can be arbitrarily selected to move up and down. The open / close position can be set freely. For example, if there is a position where you do not want to provide the blade opening in the same blind, or conversely, there is a position where you want to always secure more lighting and ventilation, further provide multiple blade opening and closing strings to operate. By setting the blade to be opened and closed for each blade opening and closing cord in advance, it is convenient to select and use the blade opening and closing cord and change the position of the blade opening part to finely control light shielding. Can be used.

In the blind with the chevron blade of claim 5, the height of the butterfly chevron blade is changed to adjust the line-of-sight through the blind, the ventilation and the daylighting. If you adjust the height until it becomes, the horizontal line of sight and ventilation can be maximized. Moreover, its operation is very easy.

When the interlocking blades with the angled blades having the outer frame according to the sixth and seventh aspects are used, they are placed on a sliding door groove and slid, or wheels are attached to roll on rails.
As you can freely move left and right like a sliding door,
It cannot be fitted with conventional blinds, for example, it can be used as a sweep window for a veranda that frequently goes in and out, or can be used instead of shoji and sliding doors in a Japanese-style room. In the latter case, if you use a blade with a paper-like appearance, such as a white translucent plastic plate,
Almost no discomfort when used as a substitute for shoji or fusuma. Rather, the advantage of being able to block light and protect the privacy while ventilating is greater.
Also, such mounting a simple rail by the window easily installed, and so well matched to the Japanese-style room as aesthetics, the Japanese-style not provided with shoji, of these benefits
It can be a powerful means of realizing it.
