Various embodiments of the present invention will be described below. The first to third embodiments of the present invention described below can be combined with each other. In addition, as to the reference numerals assigned to the respective elements, there are also different embodiments in which different elements are assigned the same reference numerals.

[First Embodiment]

Hereinafter, a horizontal shutter according to a first embodiment of the present invention will be described with reference to the drawings.

As shown in FIG. 1, the horizontal blind 10 includes a top box 11 mounted on a ceiling, a window frame, a curtain box, and the like, and a plurality of slats 12 that block sunlight. In addition, the horizontal shutter 10 includes a ladder rope 13 that supports the slats 12 to be tilt-adjustable, a bottom rail 14 located on the lower side of the slats 12 on the lowest level, and a lifting belt 15 whose one end is fixed to the bottom rail 14. .

The slat 12 is formed of a synthetic resin plate, a metal plate such as stainless steel, or the like, and is formed in an elongated rectangular thin plate shape with an arc-shaped surface on the upper surface portion. Further, the slats 12 may be formed of a wooden board. The plurality of slats 12 are arranged in the height direction, and are supported by the ladder rope 13 suspended from the top box 11 so as to be tiltable and adjustable. A bottom rail 14 having a length substantially the same as that of the slat 12 is disposed on the lower side of the bottom slat 12. The bottom rail 14 functions as a weight member while maintaining a state in which most of the slats 12 are lowered. The bottom rail 14 has substantially the same length and width as the slats 12. When the bottom rail 14 is pulled up, most of the slats 12 are stacked on the bottom rail 14. The front end portion of the ladder rope 13 is fixed to the bottom rail 14. A lifting belt 15 pulled out from the top box 11 is fixed to the bottom rail 14.

Most of the slat 12 is composed of a plurality of slat 12 arranged along the lifting direction. An example of a slat group. First through holes 22 are formed at both ends in the longitudinal direction of the slat 12 constituting the slat group, and a lifting belt 15 as an example of the first lifting member passes through the first through holes formed in the plurality of slat 12. 22 each. In each of the plurality of slat 12 constituting the slat group, the lifting belt 15 as an example of the second lifting member does not pass through the central portion in the longitudinal direction of the slat 12, so that it is not necessary for the lifting belt 15 to pass through. Through-hole. In the area occupied by such a slat group, in the central portion in the longitudinal direction of the slat 12, it is possible to ensure high light-shielding properties due to the absence of the aforementioned through-hole.

Inside the top box 11, there are provided lifting mechanisms such as a plurality of rollers 17 that wind up the lifting belt 15 and a shaft 18 that rotates the plurality of rollers 17 in synchronization. The lifting mechanism is electrically driven, for example, and uses a motor 20 disposed inside the top box 11 as a driving source. The motor 20 is driven to lift and lower the slat 12 according to a user's operation. When the lifting mechanism is manual, the operation rope is pulled out from the top box 11 and the operation rope is operated to rotate the shaft 18 via a transmission mechanism such as a pulley to which the operation rope is hooked.

By winding up the lifting belt 15, the bottom rail 14 rises. As the bottom rail 14 rises, most of the slats 12 are stacked on the bottom rail 14 in order from a position close to the bottom rail 14. When the lifting belt 15 is pulled out, the bottom rail 14 is lowered, and as the bottom rail 14 is lowered, most of the slats 12 are lowered until they are supported by the ladder rope 13.

As shown in each of FIGS. 1 to 3, two ladder ropes 13 are arranged near both ends in the longitudinal direction of the slat 12, and one ladder rope 13 is arranged near the long side of the slat 12. Near the central part. The three lifting belts 15 are arranged near the three ladder ropes 13. Two lifting belts 15 located at both ends in the longitudinal direction of the slat 12 are arranged inside the room, and one lifting belt 15 located at a central portion in the longitudinal direction of the slat 12 is arranged outside the room. Hereinafter, the lifting belt inside the room will be referred to as the first lifting belt 15a, and the lifting belt outside the room will be referred to as the second lifting belt 15b.

As shown in FIG. 4, the front end portions of the two first lifting belts 15 a are fixed to the long side end portions of the inside of the room of the bottom rail 14 together with the longitudinal lines 13 a of the two ladder ropes 13 by the holder 16. . The front end portion of one second lifting belt 15b is fixed to the central portion in the longitudinal direction of the outside of the room of the bottom rail 14 together with the longitudinal line 13a of the ladder rope 13 by the belt holder 16.

As shown in FIG. 4, the ladder rope 13 includes a pair of vertical lines 13 a extending in the height direction of the horizontal shutter 10 and a horizontal line 13 b provided between the vertical lines 13 a. The horizontal line 13b supports each slat 12 from the lower side. In addition, the horizontal line 13b is formed in a ring shape from an upper horizontal line and a lower horizontal line, and the slat 12 can support the slat 12 between the upper horizontal line and the lower horizontal line. The length of the slat 12 that protrudes from the ladder rope 13 located on both end portions to the end portion is such that the slat does not flex due to its own weight, and is about 150 mm to 200 mm, for example.

The longitudinal line 13a of the ladder rope 13 includes a micro-piece 13c through which the second lifting belt 15b passes. The micro-piece 13c is an annular body formed by pulling out a thread from the longitudinal line 13a when the ladder rope 13 is a braided line. The micro-piece 13c is provided on the longitudinal line 13a located outside the room, and the second lifting belt 15b extending toward the outside of the room is passed through. The floating of the second lifting belt 15b is suppressed by the second lifting belt 15b passing through the micro-piece 13c, and the second lifting belt 15b is supported on the micro-piece 13c so as to follow the longitudinal line 13a of the ladder rope 13. 2nd lift The belt 15b does not need to pass through all the micro pieces 13c, and the longitudinal line 13a may be provided with the micro pieces 13c that do not allow the second lifting belt 15b to pass. In addition, although the description has been given that the micro-piece 13c is formed by a line at a position where the vertical line 13a and the horizontal line 13b intersect and becomes an annular portion, it may be configured that a resin-molded annular body is integrally provided on the vertical line 13a.

A base end portion of the longitudinal line 13 a of the ladder rope 13 is fixed to the inside of the top box 11, and a front end portion of the longitudinal line 13 a of the ladder rope 13 is fixed to the bottom rail 14 by a belt holder 16. In addition, the front end portion of the elevating belt 15 is sandwiched and fixed between the bottom rail 14 and the belt holder 16 together with the front end portion of the longitudinal line 13 a of the ladder rope 13. Furthermore, an upper surface portion of the bottom rail 14 opposed to the lowermost slat 12 is provided with a guide position for pulling out the two first lifting belts 15a extending along both sides in the longitudinal direction of the inside of the room. Belt guide member 19.

The two first lifting belts 15 a on both ends in the longitudinal direction derived from the belt guide 19 are derived from the first long side 21 a side of the bottom rail 14, and the first one in the central portion derived from the belt holder 16. The two lifting belts 15 b are led out from the second long side portion 21 b side of the bottom rail 14. As a result, the bottom rail 14 is supported by the first lifting belt 15a and the second lifting belt 15b at three positions from both sides, and does not tilt toward the front side that is the inside of the room or the rear side that is the outside of the room, that is, does not tilt forward and backward , And rise and fall in a stable state.

As shown in each of Figs. 5 (a), (b), and (c), all the slats 12 included in the horizontal shutter have an elongated rectangular thin plate shape extending in the longitudinal direction. On the other hand, all the slats 12 included in the horizontal shutters include the presence or absence of through-holes and three types of plates with different positions of the through-holes. Article 12.

As shown in FIG. 5 (a), the uppermost slat 12a is formed at the center of the second long side portion 21b located outside the room with a guide for the second lifting belt 15b as an example of the second lifting member. Second through hole 23. The second elevating belt 15 b extending to the outside of the room passes through the second through hole 23. The second through hole 23 is a rectangular through hole slightly larger than the cross-sectional shape of the second lifting belt 15b. The second lifting belt 15b is substantially parallel to the main surface of the slat 12a and cooperates with the winding surface of the drum 17. Guided by winding. The first long side portion 21a inside the room of the uppermost slat 12a is not formed with any through holes. The second through hole 23 can be easily formed in the slat 12 a by punching. .

As shown in FIG. 5 (b), the first long side portion 21 a inside the room and the second long side portion 21 b outside the room have no through holes formed in the slat 12 b from the second floor from the top.

As shown in FIG. 5 (c), the first through holes 22 are formed in both ends of the first long side portion 21a of the slat 12c from the third floor from the top. Most of the slat 12c after the third layer except the slat 12a closest to the top box 11 and the second slat 12b are the slat 12 constituting the above-mentioned slat group.

As an example of the first elevating member, two first elevating belts 15 a extending inward of the room pass through the two first through holes 22. The first through hole 22 is a rectangular through hole slightly larger than the cross-sectional shape of the first lifting belt 15a. The first lifting belt 15a is substantially parallel to the main surface of the slat 12c. The winding system is guided in accordance with the winding surface of the drum 17. In addition, the slat 12c from the third layer onward has no through-holes formed between the first through-holes 22 on both end portions. The first through hole 22 can be easily formed in the slat 12c by punching.

Here, in a state where the top surface of the top box 11 is mounted in the window frame, both ends in the longitudinal direction of the slat 12 are arranged near the vertical frame of the window frame, in other words, the light shielding property is ensured by a wall or the like. s position. In addition, in a state where the top box 11 is front-mounted so as to cover the window frame, or in a state where the top box 11 is mounted to a curtain box or a curtain rail, both ends in the longitudinal direction of the slat 12 are also disposed on the window frame. Near or outside the vertical frame. Therefore, even when light leaks from the first through hole 22, such light is not noticeable to the user. On the other hand, the second through-holes 23 formed between the first through-holes 22 and formed in the central portion in the longitudinal direction of the slat 12 also have a large amount of light leakage from the second through-holes 23. More eye-catching.

In this regard, in the above-mentioned horizontal blinds, all of the slat 12 also occupies most of the slat 12 after the third layer, and is formed only at both ends in the longitudinal direction of the slat 12. In the first through hole 22, no other through hole is formed between the two first through holes 22. Therefore, the light-shielding property can be improved for the entire slat group or the area occupied by the entire slat 12.

In addition, the first through hole 22 is biased toward the first long side portion 21a located inside the room of the slat 12c. With such a position of the first through-hole 22, all the slats 12 are inclined in one direction, and when the fully-closed state is shielded from sunlight, the long sides overlap with each other, and light leakage from the first through-hole 22 is easily suppressed. .

However, as shown in FIG. 5 (a), a second through hole 23 is provided at the center portion in the longitudinal direction of the slat 12 a closest to the top box 11 to the side of the second long side portion 21 b. The uppermost slat 12a is close to the top box 11 and is close to the window frame even when it is installed on the front surface or the top surface, and is located on the upper side of the window frame. Therefore, even when light leaks from the second through hole 23, the light enters the shadow of the top box 11 and the like, and the amount of light is small, and the overall light-shielding property is not significantly deteriorated.

In addition, as shown in FIG. 5 (b), through-holes are not formed at all in the slat 12b of the second layer from the top, so there is no concern about light leakage of the slat 12b of the second layer. In addition, neither the first lifting belt 15a nor the second lifting belt 15b passes through the slat 12b. According to such an arrangement of the lifting belt 15, when the slat 12 is inclined, the load on the slat 12 from the first lifting belt 15 a and the second lifting belt 15 b, especially to the slat 12 on the first and third floors. The load can be suppressed, so that all the slats 12 can be smoothly tilted.

As shown in FIG. 4, the first lifting belt 15 a fixes the base end portion to the drum 17. The first lifting belt 15a passes from the top box 11 through the outside of the uppermost slat 12a and the second slat 12b, and passes between the second slat 12b and the third slat 12c. The first through holes 22 of the three-layer slat 12c. The first elevating belt 15 a passes through the first through hole 22 with respect to the slat 12 c of the third layer and later, and the front end portion is fixed to the both end portions of the bottom rail 14 by the belt holder 16.

The second lifting belt 15 b fixes the base end portion to the drum 17. After the second lifting belt 15b is pulled out from the top box 11, it passes through the second through hole 23 of the uppermost slat 12a, and passes through the uppermost slat 12a. It is unrolled toward the outside of the slat 12c with the slat 12b of the second layer. The second lifting belt 15b extends along the longitudinal line 13a of the ladder rope 13 on the outside of the second long side portion 21b with respect to the slat 12c of the third and subsequent layers, and passes through the miniature piece 13c of the ladder rope 13. It is possible to suppress the second lifting belt 15b from floating. In addition, the second lifting belt 15b does not need to pass through all the micro-pieces 13c. A front end portion of the second lifting belt 15 b is fixed to a central portion of the bottom rail 14 by a belt holder 16.

A slat presser 24 is provided on the uppermost slat 12 a at a position where the longitudinal lines 13 a of the three ladder ropes 13 extend. In addition, a slat presser 24 is also provided at a position extending from the slat 12b on the second floor from the longitudinal line 13a of the ladder rope 13 on both sides of the slat 12b. The slat presser 24 engages the horizontal line 13b of the ladder rope 13 at the long side of the slat 12, thereby suppressing the slat 12a, 12b from shifting laterally. In addition, the slat presser 24 suppresses repeated contact between the longitudinal line 13a and the edge portion of the long side portion of the slat 12a, 12b, thereby causing the longitudinal line 13a to be cut and abraded. Furthermore, the slat presser 24 reduces the load applied to the slat 12 from the longitudinal line 13a, thereby suppressing the slat 12 from deforming. Furthermore, the slat pressing member 24 can reduce the friction between the longitudinal line 13 a and the slat 12, so that the other slat 12, 12 c can smoothly move obliquely following the uppermost slat 12 a. This slat presser 24 can obtain the same effect even if it is provided on the slat 12c of the third layer or later.

Next, the fully closed state of the slat 12 of the horizontal shutter 10 comprised as mentioned above is demonstrated using FIG.6 and FIG.7. In addition, in FIG. 7, the ladder rope 13 is omitted.

When the slat 12 is in a fully closed state, the bottom rail 14 and the slat 12 are in a lowered state, and all the slat 12 is inclined to move in one direction and is in a state of blocking sunlight. In this case, on the outside of the room, the second long side portion 21 b of the outside of the room of each of the slats 12 faces the lower side. Generally speaking, Sunlight shines through the windows from above. At this time, the gap between the adjacent slats 12 and the slats 12 is inclined from the outside to the inside of the room from bottom to top. Therefore, the open end of the gap outside the room faces the lower side, making it difficult for sunlight to enter, and has a structure that improves the light-shielding property.

At this time, the long-side portions overlap each other with the slat 12 adjacent to each other. For example, the second through hole 23 of the second long side portion 21b outside the room formed by the uppermost slat 12a becomes the lower side, and the first through hole 23 located inside the room on the upper side of the slat 12b from the second floor from the top. The long side portion 21a is overlapped and shielded. In addition, even if the first through-holes 22 are formed in the third layer and later, the second long side portion 21b outside the room adjacent to the slat 12b from the second floor and the slat 12c after the fourth floor are adjacent. Shelter. For example, the first through hole 22 of the slat 12c of the third layer is located on the upper side and is shielded by the second long side portion 21b located on the lower side of the slat 12b of the second layer from the top. The first through holes 22 formed in the slat 12c after the fourth layer are also located on the upper side, and are shielded by the second long side portion 21b on the lower side of the slat 12c adjacent to the upper side. Therefore, the first through hole 22 and the second through hole 23 are obscured by the long sides of the adjacent slat 12 when the slat 12 moves obliquely in one direction and becomes fully closed. In the fully closed state of the slat 12, the horizontal louver 10 shields the first through-hole 22 and the second through-hole 23 to improve the light-shielding property.

In addition, the horizontal louver 10 may be tilted in the other direction, so that the tilt of the slat 12 is reversed from FIG. 6 and FIG. 7 to be fully closed in the reverse direction. In this case, the first through hole 22 of the slat 12c in the third layer from the top is located on the lower side, and is shielded by the second long side portion 21b on the upper side of the slat 12b in the fourth layer from the top. However, since the second through hole 23 is located on the upper side and there is no slat 12 thereon, the second through hole 23 is not shielded. In this case, the second through hole 23 also becomes the top box 11 Shadows while reducing incident sunlight.

When the bottom rail 14 is pulled up, the lifting belt 15 is wound around the drum 17. The second lifting belt 15b on the outside of the room was wound around the drum 17 shortly before passing through the second through hole 23 of the uppermost slat 12a so as to be substantially parallel to the main surface of the slat 12a and rectified into a roll with the drum 17. Take the state of surface fit.

The first lifting belt 15a on the inside of the room also passes through the first through hole 22 from the slat 12c on the third layer from the lower side than the slat 12a on which the second through hole 23 is formed, and the main part of the slat 12c The face is substantially parallel and corrected to fit the winding surface of the drum 17. Therefore, the first lifting belt 15 a is also wound around the winding surface of the drum 17 without twisting. That is, both the first lifting belt 15a and the second lifting belt 15b are wound around the drum 17 without twisting. Therefore, the three rollers 17 can take up the same amount of three lifting belts 15a, 15b at the same speed, so that the slats 12 can be prevented from tilting during winding.

The horizontal shutter 10 as described above can obtain the effects listed below.

(1) Compared with a structure in which a through-hole is formed between the first through-holes 22 to allow the second lifting belt 15b to pass through, the light-shielding property can be improved in the entire area where the light-shielding property is particularly required.

(2) Since the long side portions overlap each other in the fully closed state, the first through hole 22 is closed by the second long side portion 21 b of the adjacent slat 12 c, and light leakage from the first through hole 22 can be suppressed.

(3) A second through hole 23 that is biased toward the second long side portion 21b is formed at the center portion in the longitudinal direction of the uppermost slat 12a. However, even if light leaks from the second through hole 23 in this way, the light amount thereof It is also less, and does not significantly reduce the overall light-shielding property.

(4) The second lifting belt 15 b is integrated into a state in which the second lifting belt 15 b and the winding surface of the drum 17 are matched by the second through holes 23 of the uppermost slat 12 a. Therefore, the second lifting belt 15b is not twisted, and the drum 17 can wind the second lifting belt 15b.

(5) The first elevating belt 15a can also be integrated into a state where the first elevating belt 15a and the winding surface of the drum 17 cooperate with each other through the first through hole 22 to the slat 12c of the third layer. Therefore, the first lifting belt 15a is also wound without being twisted.

(6) The uppermost slat 12a passes only the second lifting belt 15b through the second through hole 23, and the first through hole 22 through which the first lifting belt 15a passes is not formed. Therefore, the slats 12a in the uppermost stage can be smoothly moved with tilt.

(7) The second lifting belt 15b passes through only the second through hole 23 of the uppermost slat 12a, and the lower layers pass through the outside of the slat 12b and the slat 12c. Therefore, in the fully closed state, the second lifting belt 15b does not come into contact with the curved convex surface of each slat 12 and does not apply an excessive load, so that the slat 12 can be smoothly inclined to move.

(8) The uppermost slat 12a allows the second lifting belt 15b to pass through the second through hole 23, so that the lateral displacement of the slat 12a can be prevented.

(9) The slat 12c after the third layer also allows the first lifting belt 15a to pass through the first through hole 22, so that the slat 12c can be prevented from being displaced laterally.

In addition, the above-mentioned horizontal louver 10 may be appropriately modified and implemented as follows.

‧ The first through holes 22 at both ends in the longitudinal direction of the slat 12 may be formed outside the room. The second through hole 23 at the center portion in the longitudinal direction of the slat 12 may be formed inside the room, or may be eliminated from the slat 12.

‧ The first through hole 22 may be formed in the uppermost slat 12a and the second slat 12b, and all the slat 12 may form a single slat group.

• The number of lifting belts 15 and the number of ladder ropes 13 are not limited to the above examples. For example, four ladder ropes 13 and four lifting belts 15 may be used. In horizontally long horizontal blinds, seven ladder ropes 13 and four lifting belts 15 may be used. Furthermore, the number of ladder ropes 13 can be five, and the number of lifting belts 15 can be three. That is, in any case, a plurality of second lifting belts 15 b may be provided between the first lifting belts 15 a located at both ends of the slat 12.

As described above, in the case of a horizontally long louver, as described above, the number of the ladder ropes 13 is more than three, and the number of the lifting belts 15 is also more than three. In conjunction with this, the bottom rail 14 also uses the same long parts as the slat 12.

In the example of FIG. 8, for each horizontally large horizontal blind, five ladder ropes 13 and four lifting belts 15 are used. Specifically, in the slat 12c after the third floor, the two first lifting belts 15a extend toward both end portions in the longitudinal direction of the slat 12 inside the room. In addition, outside the room, two second lifting belts 15b extend between the two first lifting belts 15a. In addition, the bottom rail 14 uses a member having a larger width than the width between the long side portions of the slats 12, so that the strength can be improved.

In the example of FIG. 8, the first lifting belt 15 a is passed through the first through hole 22 only at both ends of the slat 12 c, and the second lifting belt 15 b located between the first lifting belt 15 a is placed on the slat. The outside of the second long side portion 21b of 12 extends in the raising and lowering direction. Therefore, when the slat 12 is fully closed, Light is leaked from only the surrounding first through-holes 22, thereby improving the overall light-shielding property.

‧ The first through hole 22 through which the first lifting belt 15a located at both ends of the slat 12 passes may not be biased toward one side of the first long side portion 21a inside the room of the slat 12. That is, the first through hole 22 may be biased toward one side of the second long side portion 21 b outside the room. Further, as shown in FIG. 9, the first through hole 22 may be provided in a central portion between the first long side portion 21 a and the second long side portion 21 b of the slat 12.

In this case, when the slat 12 is in the fully closed state, the first through holes 22 are not all closed by the slat 12 adjacent to each other. That is, the first through hole 22 is partially closed by the adjacent slat 12 based on the installed position, or is not entirely closed. In this case, since the first through-holes 22 are provided at both end portions in the longitudinal direction, it is possible to increase the number of holes compared to the case where through-holes through which the second lifting belt 15b passes are provided between the first through-holes 22. Overall shading.

As shown in FIG. 10, the second lifting belt 15b may extend on the first long side portion 21a and the second long side portion 21b of the slat 12c. In this case, the plurality of second lifting belts 15b are respectively provided in the short-side direction of the slat 12 and are arranged in a zigzag manner. A plurality of second lifting belts 15b are arranged between the two second lifting belts 15b. In this case, the first lifting belts 15 a located on both sides in the longitudinal direction of the slat 12 c pass through the first through holes 22 provided on both sides in the longitudinal direction of the slat 12 c.

‧As shown in FIG. 11, the lifting member of the lifting bottom rail 14 can be a string-shaped member such as a round belt instead of a belt-shaped member such as a flat belt, like the first lifting belt 15 a and the second lifting belt 15 b.

‧ As shown in FIG. 12, in the horizontally large blinds, more ladder ropes 13 and lifting belts 15 can be used. That is, in the example of FIG. 12, the first through holes 22 are formed on both end portions of the slat 12 c, and the first lifting belt 15 a is disposed. In addition, second lift belts 15b are arranged every other between the ladder ropes 13. The second lifting belt 15b may be arranged not only on the first long-side portion 21a side, but also on the second long-side portion 21b side.

‧ As shown in FIG. 13, the horizontal louver 10 is mounted on a window frame 30 to shield sunlight from the light-transmitting area 33 in the window frame 30. As a method for attaching the horizontal shutter 10 to the window frame 30, first, the method shown in FIG. 13 is provided. In FIG. 13, the horizontal blinds 10 cover the window frame 30 to reduce light leakage. When the window frame 30 is hidden, the curtain box 31 is mounted on the upper portion of the window frame 30 provided on the inside of the room through the top surface. In this case, the horizontal length of the horizontal louver 10 is set to be longer than the interval A between the vertical frames 30 a and 30 a of the window frame 30. In the height direction, the bottom rail 14 is set to be longer than the interval B between the upper and lower horizontal frames 30b and 30b so that the bottom rail 14 is positioned lower than the horizontal frame 30b on the lower side of the window frame 30. Thereby, the horizontal louver 10 covers the entire light-transmitting area 33 of the window frame 30.

In this case, the first through-hole 22 and the first lifting belt 15a passing through the first through-hole 22 of the slat 12 are located along the vertical frames 30a, 30a of the window frame 30 or at the vertical frames 30a, 30a. Outside. In this case, light is not leaked from the first through hole 22, and light shielding properties can be improved. If the first through hole 22 is positioned close to the vertical frames 30a and 30a inside the window frame 30, it will become a shadow of the vertical frames 30a and 30a, and the amount of transmitted light can be reduced.

In addition, the bottom rail 14 is located below the horizontal frame 30 b on the lower side of the window frame 30. therefore, If the lowermost slat 12c or the second through hole 23 of the slat 12c close to it is positioned on the inner side of the lower horizontal frame 30b and the lower horizontal frame 30b, the light only penetrates into the user's feet Etc., so it is unobtrusive for the user.

‧ As shown in FIG. 14, the horizontal shutter 10 is also installed inside the window frame 30. In this case, the horizontal length of the horizontal shutter 10 is set to be substantially the same as the interval A between the vertical frames 30 a and 30 a of the window frame 30. In the height direction, the bottom rail 14 is set to have the same length as the interval B between the upper and lower horizontal frames 30b and 30b so that the bottom rail 14 is positioned on the horizontal frame 30b on the lower side of the window frame 30. Thereby, the horizontal louver 10 covers the entire light-transmitting area 33 in the window frame 30.

In this case, the first through-hole 22 of the slat 12, the first lifting belt 15a passing through the first through-hole 22, and the first through-hole 22 through which the first lifting belt 15a passes are from the center of the light-transmitting area 33. A user, such as a part, is not a prominent part when viewed, and is located near the vertical frame 30 a of the window frame 30. In particular, in the examples of FIGS. 9 to 12, the first through holes 22 are provided at both ends in the longitudinal direction of the slat 12 c. Therefore, the first through hole 22 is located near the vertical frame 30a. Also with this horizontal shutter 10, the through-holes are not formed between the second through-holes 23 of the slat 12, and the overall light-shielding property can be improved.

Furthermore, in the case of FIG. 14, the second through-holes 23 may be provided in the plurality of slats 12 close to the bottom rail 14. In this case, the length in the height direction of the horizontal louver 10 is made slightly longer than the interval B between the upper and lower horizontal frames 30b and 30b. As a result, when the bottom rail 14 is lowered, a plurality of slats overlap on the lower horizontal frame 30b, thereby hiding the second through hole 23. Therefore, it is possible to suppress the 23 Worry of light leakage.

[Second Embodiment]

First, a horizontal shutter according to a second embodiment of the present invention will be described with reference to FIGS. 15 to 22. FIG. 15 is a perspective view showing a schematic configuration of a horizontal louver according to a second embodiment of the present invention. FIG. 16 is a plan view of a slat s4 of a horizontal shutter according to a second embodiment of the present invention. FIGS. 17 (a) and 17 (b) are explanatory diagrams when the slats s4 of the horizontal shutters according to the second embodiment of the present invention are tilted. 18 (a) and 18 (b) are explanatory diagrams when the slat s4 of the horizontal shutter of the second embodiment of the present invention is shielded. FIG. 19 is a side view showing a schematic configuration of a part of a horizontal louver according to a second embodiment of the present invention. 20 is a partial side cross-sectional view illustrating the shielding effect of the horizontal blinds according to the second embodiment of the present invention. 21 (a) and 21 (b) are respectively a partial side sectional view and a comparative example for explaining the shielding effect of the horizontal blinds according to the second embodiment of the present invention in more detail. 22 (a) and 22 (b) are plan views illustrating the lateral shift and twist suppression effect of the horizontal blinds according to the second embodiment of the present invention.

As shown in FIG. 15, in the horizontal blinds of the present embodiment, the ladder ropes s7L, s7M, and s7R are suspended from the left end side, the center portion side, and the right end side of the long box direction of the top box s1. Supports most slats s4. The bottom rail s8 is suspended and supported on the lower ends of the ladder ropes s7L, s7M, and s7R. In addition, three or more lifting ropes s6L, s6M, and s6R, which are installed on the outdoor or indoor ladder ropes s7L, s7M, and s7R, are suspended from the top box s1, and the lifting ropes s6L, s6M, and s6R are suspended. A bottom rail s8 is installed at the lower end.

The mechanism for adjusting the angle of most slats s4, the mechanism for raising and lowering several slats s4, and the operation unit for operating the above-mentioned mechanism can be implemented in various known forms. The above-mentioned mechanism is not directly related to the gist of the present invention. So briefly explain an example.

A support member that supports the ladder ropes s7L, s7M, and s7R and the lifting ropes s6L, s6M, and s6R is disposed in the top box s1, and a rectangular rod-shaped drive shaft passes through the support member (not shown). An inclined drum is rotatably supported by such a supporting member, and the drive shaft cannot pass through the inclined drum in a relatively rotatable manner. Therefore, if the drive shaft rotates, the inclined drum rotates, and the angles of the plurality of slats s4 suspended by the ladder ropes s7L, s7M, and s7R can be adjusted.

In addition, in order to be able to pull the lifting ropes s6L, s6M, and s6R into or out of the top box s1, the support member is provided with a take-up shaft that cannot be relatively rotated with respect to the drive shaft. (Not shown). Therefore, if the drive shaft rotates, the inclined drum rotates, and an angle of most slats s4 suspended by the ladder ropes s7L, s7M, and s7R is inclined in a direction substantially perpendicular to the horizontal direction. The lifting and lowering ropes s6L, s6M, and s6R of the shaft can be taken up or unrolled, and the slat s4 can be raised and lowered by raising and lowering the bottom rail s8.

An operation pulley for operating the rotation of the drive shaft is housed on the right end portion side of the top box s1, and an endless operation rope s5 stretched over the operation pulley is provided from the front surface of the right end portion side of the top box s1. The outlet 1a hangs down. In addition, a stopper is provided in the top box s1 to lock the rotation of the drive shaft. Therefore, by operating the operation rope s5, the rotation of the drive shaft can be operated, and the angle of the majority of the slats s4 supported by the ladder ropes s7L, s7M, and s7R via the support member can be adjusted. Therefore, most of the slats s4 are raised and lowered by the lifting ropes s6L, s6M, and s6R.

In the horizontal blinds of this embodiment, as shown in FIG. 16, most of the lifting ropes s6L, s6M, and s6R among the lifting ropes s6L, s6R are configured to pass through one edge portion provided in the short-side direction of each slat s4. (Outdoor side edge portion) A long hole-shaped through hole s4a (through-hole) extending in the short-side direction in the vicinity is suspended, and the lifting rope s6M is constituted by the other edge portion along the short-side direction of each slat s4 Hang down. The long hole-shaped through hole s4a is preferably formed to extend from one edge portion (outdoor side edge portion) in the short-side direction of each slat s4 to a center portion in the short-side direction of each slat s4. In addition, each slat s4 is placed at a plurality of positions in the long-side direction of the top box s1 and is connected with a horizontal line s7a between a pair of ladder ropes s7L (or s7M, s7R) suspended at a predetermined interval. And s7b, respectively.

In particular, the long hole-like through-hole s4a does not hinder the slanting action of each slat s4, and is formed so that at least the through-hole s4a is shielded by the edge portion of each slat s4 when each slat s4 is tilted in a shielding state The location of the part.

More specifically, as shown in FIG. 17, in order to pass the lifting ropes s6L, s6R, a long hole-shaped through hole s4a is formed near the outdoor side edge portion in the short side direction (that is, the front-rear direction) of each slat s4. Therefore, when each slat s4 is in a standard state (refer to FIG. 17 (a)) and each slat s4 is in an inclined state (refer to FIG. 17 (b)), the lifting ropes s6L, s6R can also be suspended toward it. Erection without burden in the vertical direction. In addition, since the long hole-shaped through-hole s4a is provided near the edge portion on the outdoor side, as shown in FIG. 17 (b), light leakage from the through-hole s4a can be suppressed, and the light-shielding property against external light can be improved.

That is, as shown in FIG. 18 (a), the long hole-shaped through hole s4a is formed in a direction from one edge portion (outdoor side edge portion) of the short side direction of each slat s4 to the short side direction of each slat s4. It extends within the range of the central part. When each slat s4 is in a shielding state, each slat s4 is inclined in a direction substantially perpendicular to the horizontal direction. At this time, at least a part of the through hole s4a is shielded by the edge portion of each slat s4. . In addition, as described later, the entire through-hole s4a may be shielded by the edge portion of each of the slats s4. Accordingly, light leakage from the through-hole s4a can be suppressed, and the light-shielding property against external light can be improved. Furthermore, by providing the through-hole s4a near the edge portion of the outdoor side, the through-hole s4a is fully closed as in the state of FIG. 18 (a) (or FIG. 17 (b)) as an effect other than improving the light-shielding property. It is completely hidden by the downstream slat s4, so the design is also improved.

In addition, as shown in FIG. 18 (b), the short diameter D of the long hole-like through-hole s4a is preferably formed to be approximately the same as the cross-sectional diameter d of the lifting ropes s6L and s6R passing through it. Accordingly, even when the entire through-hole s4a is not shielded by the edge portion of each slat s4, light leakage from the through-hole s4a can be effectively suppressed. The “short diameter D of the through hole s4a that is substantially the same as the cross-sectional diameter d of the lifting ropes s6L and s6R” means a diameter that does not hinder the movement of the lifting ropes s6L and s6R relative to the through hole s4a. The short diameter D is exactly the same as the cross-sectional diameter d, or the short diameter D is slightly larger than the cross-sectional diameter d. In addition, the diameters of the ladder ropes s7L and s7R are substantially the same as the short diameter D of the long hole-like through-hole s4a, It is larger than its thickness, so that light leakage can be suppressed more reliably.

Further, in addition to the three lifting ropes s6L, s6M, and s6R as in the present embodiment, it may be formed in a form using four or more lifting ropes. In this case, most At least two of the lifting ropes hang down through the long hole-shaped through hole s4a, and at least one of the lifting ropes other than the at least two lifting ropes runs along the short side direction of each slat s4. The other edge hangs down.

At this time, the lifting ropes (the lifting ropes s6L, s6R in the examples of FIG. 15 and FIG. 16) which hang down in the “longest position away from the two ends” in the respective long sides of the plurality of lifting ropes s4 among the plurality of lifting ropes. ) Is configured to pass through a long hole-shaped through hole s4a provided near one edge portion (outdoor side edge portion) of the short-side direction of each slat s4 and extending in the short-side direction, and to pass through the long-hole-shaped through-hole The hoisting ropes other than the hoisting rope of the hole s4a (the hoisting rope s6M in the examples of FIG. 15 and FIG. 16) do not use a notch or a through hole, but are preferably configured as the other edge along the short side direction of each slat s4 Part (interior side edge part) hangs down. As a result, light leakage can be suppressed more effectively, and lateral displacement and twist of the slat s4 can be suppressed. This will be described in detail later.

In the horizontal blinds of the present embodiment, each slat s4 is composed of a flat hard material (for example, wood), and the ladder ropes s7L, s7M, and s7R and the lifting ropes s6L, s6R, and The placement position of s6M can suppress light leakage and improve assemblability, and can effectively suppress the lateral shift and twist of the slat.

As shown in FIG. 15 and FIG. 16, a pair of ladder ropes s7L, s7M, and s7R are suspended opposite each other in the short-side direction (that is, front-rear direction) of the slat s4, and a predetermined interval is set between the pair of ladder ropes s7L. The horizontal lines s7a and s7b crossing in an X shape are connected. As shown in FIG. 19, the slat s4 is uploaded on the horizontal lines s7a and s7b. Similarly, a pair of ladder ropes s7M (or s7R) are connected at predetermined intervals. The horizontal lines s7a and s7b crossing in an X shape are carried on the horizontal lines s7a and s7b.

Conventional horizontal shutters also have a form that uses a thin sheet-like shape made of a flexible material made of aluminum that can be bent. In the case of using such a bent sheet, The slat can be easily passed between the transverse lines s7a and s7b crossing in an X shape using its bendability, so its assemblability is not a great burden. In addition, in the existing horizontal blinds, instead of the lifting rope, the ladder rope is engaged with the notch of the slat, thereby suppressing the lateral deviation of the slat.

On the other hand, as shown in FIG. 15 and FIG. 19, the slat s4 of the horizontal louver of the present embodiment has a flat plate shape made of a hard material that cannot be bent such as wood. It cannot be said that it is easy to assemble the flat slat s4 made of the hard material between the horizontal lines s7a and s7b crossing the X shape. Therefore, in the horizontal blinds of the present embodiment, the flat slat s4 made of the hard material is configured to be carried on the horizontal lines s7a and s7b crossing in an X shape, so that the assemblability can be improved. In addition, the slats s4 of the horizontal blinds of the present embodiment are not provided with a notch that engages with the horizontal lines s7a, s7b of the ladder ropes s7L, s7M, and s7R. This not only suppresses the light leakage, but also allows the slats s4 to Installation of the horizontal lines s7a, s7b of the ladder ropes s7L, s7M, and s7R is facilitated.

In general, if a flat slat s4 is not placed on the horizontal lines s7a and s7b without a notch, a lateral shift in the long-side direction (that is, left-right direction) of each slat s4 is generated and acts on each slat s4. Twisting in the short side direction (that is, the front-rear direction), during the lifting operation of the slat s4, the tilt operation A malfunction may occur during operation, but the lateral blinds of the present embodiment can also suppress such lateral shift and twist.

That is, in the horizontal blinds of the present embodiment, as shown in FIG. 15 and FIG. 16, the closest positions of both ends of the long side direction (that is, left and right direction) spaced apart from the slats s4 hang from the top box s1. The lifting ropes s6L and s6R pass through the through-holes s4a which are long holes in the front-rear direction provided near the outdoor side edge portion of the short side direction (that is, the front-rear direction) of each slat s4, and pass through the bottom rail s8. The through-holes s8L and s8R provided near the outdoor-side edge portion of the front surface are locked and mounted on the bottom surface side. In addition, at least one of the lifting ropes s6L and s6R other than the lifting ropes s6L and s6R which hang at the closest positions to both ends in the long side direction (that is, the left-right direction) of each slat s4 (that is, lifting in this example) The rope s6M) hangs along the indoor side edge portion in the short-side direction (ie, the front-rear direction) of each slat s4, and is fixed to the mounting portion s8M provided on the bottom surface along the front side of the bottom rail s8. That is, although it can be comprised so that many hoisting ropes may hang between hoisting ropes s6L and s6R, at least one of them may be hung along the edge part of an indoor side.

In the horizontal louver of this embodiment configured as described above, as shown in FIG. 18, at least a part of the through-hole s4a can be shielded by the edge portion of each slat s4, so that light leakage from the through-hole s4a can be suppressed. All the through-holes s4a are shielded by the edge portions of the slats s4. Accordingly, light leakage from the through-hole s4a can be reliably suppressed, and the light-shielding property against external light can be improved. For example, as shown in FIG. 20, the slat s4 of the present embodiment has a thickness, so in order to hide all the through-holes s4a when tilted (when fully closed), the position of the upper end sA of the downstream slat s4 is equal to The position of the upper edge sB of the through hole s4a of the upstream slat s4 becomes a horizontal position, or a square higher than the height thereof. Formula to form a through hole s4a. At this time, the lifting rope s6R (or s6L) may be slightly loosened as shown in FIG. 20.

In addition, by providing the through hole s4a near the outdoor side edge portion of the slat s4, it is possible to improve the shielding property at the time of tilt (when fully closed). For example, as in the present embodiment shown in FIG. 21 (a), if the through-hole s4a is provided near the outdoor edge portion of the slat s4, even if the hoisting rope s6R (or s6L) hangs down, it is oriented in a substantially vertical direction. In the case (see the dotted arrow), the lifting rope s6R (or s6L) and the ladder rope s7R (or s7L) do not hinder the slanting action of the slat s4, so the shielding performance is improved. On the other hand, as shown in FIG. 21 (b), if the through-hole s4a is provided near the indoor edge portion of the slat s4, when the hanging rope s6R (or s6L) hangs down in a substantially vertical direction ( (Refer to the dotted arrow), since the slanting action of the slat s4 is hindered, it may have a bad influence on its shielding property. Therefore, by providing the through-hole s4a near the edge portion of the outdoor side of the slat s4, it is possible to improve the shielding property at the time of tilt (when fully closed).

In this way, the through hole s4a is provided on the slat s4, and as shown in FIG. 16, a plurality of lifting ropes s6L, s6R, and s6M are arranged, so that even if only the slats s4 uploaded on the horizontal lines s7a, s7b, they can be as shown 20 and FIG. 21 improve the shielding performance when tilted (when fully closed). In addition, the lateral displacement (see FIG. 22 (a)) and twisting (see FIG. 22 (b)) are suppressed.

In addition, in order to suppress lateral displacement and torsion, and to further improve assemblability, as shown in FIG. 19, it is preferable that the lifting rope s6L (or s6R) is configured at a predetermined level for a large number of slats s4 (in the example shown in the figure: Lines s7a, s7b are incorporated into every five layers). In addition, it is preferable that the lifting rope s6L, The s6R is incorporated into each horizontal line s7a and s7b, and the s4 is incorporated in a symmetrical manner with respect to the center of the longitudinal direction of each slat s4 as a base point. For example, as shown in FIG. 19, for a certain slat s4, the lifting ropes s6L, s6R pass through the center portion side with respect to the corresponding horizontal lines s7a, s7b. For the other slats s4, the lifting ropes s6L, s6M pass through the outer edge portion side opposite to the central portion with respect to the corresponding horizontal lines s7a, s7b. In this way, the lifting ropes s6L and s6R are symmetrical with respect to each horizontal line s7a and s7b for each slat s4, so that the lateral deviation and twist of each slat s4 can be suppressed.

The lifting rope s6M is similarly structured so that a plurality of slats s4 can be provided with each horizontal line s7a, s7b at predetermined levels (every five levels in the example shown in the figure), but it is preferable to pass through from the viewpoint of aesthetics. Between the horizontal lines s7a and s7b (see FIG. 16). Alternatively, it may be formed as follows: When the continuous upper and lower slats s4 are interposed between the horizontal lines s7a and s7b, the upper slat s4 passes the lifting rope s6M through the horizontal s7a. The right side and the left side of the horizontal line s7b, and the lower slat s4 are made to pass through the lifting rope s6M through the left side of the horizontal line s7a and the right side of the horizontal line s7b (not shown).

In this way, at least the hoisting ropes s6L and s6M are incorporated into each of the horizontal lines s7a and s7b at predetermined levels, so that the lateral displacement and twist of each slat s4 can be suppressed, and the assemblability can be further improved.

In addition, on the upper surface of the bottom rail s8, penetrating portions s8L and s8R are provided corresponding to the vertical downstream of most of the lifting ropes s6L and s6R, respectively.

The long hole-like through-hole s4a extending in the vicinity of the short-side direction hangs down, and at least one of the lifting ropes other than the lifting ropes s6L, s6R (that is, the lifting rope s6M in this example) runs along each board. The other edge portion (interior side edge portion) of the strip s4 hangs down.

This can suppress light leakage when the slat s4 is shielded. In addition, the long hole-shaped through-hole s4a is formed at a position where at least a part of the through-hole s4a can be shielded by the edge portion of each slat s4 when the slat s4 is in a shielding state, so that it can be more suppressed. Light leakage when the slat s4 is shielded. More preferably, it is formed in a position where at least all of the through-hole s4a is shielded by the edge portion of each slat s4 when each slat s4 is inclined so as to be in a shielding state, or the short diameter of the long-hole-like through-hole s4a is formed. D is formed to be substantially the same as the cross-sectional diameter d of the passing hoisting rope s6L (or s6R), so that the light leakage can be more suppressed.

In addition, the horizontal louver of the present embodiment is configured as a slat s4, which is made of a flat hard material, and is formed by horizontal lines s7a, s7b connected between each pair of ladder ropes s7L, s7M, and s7R at a predetermined interval. A slat s4 is placed. This makes it possible to improve the assemblability when using the flat slat s4 made of such a hard material.

In addition, it is preferable that the hoisting ropes s6L and s6R hang down so that the horizontal lines s7a and s7b are inserted in a predetermined layer every a plurality of slats s4. This can further improve the assemblability.

In addition, the horizontal louver of the present embodiment has a through-hole s4a formed in a long hole shape extending in the short-side direction (that is, the front-rear direction) of the slat s4, and thus is particularly configured as a flat plate made of only a hard material. When the strip s4 is placed on the horizontal lines s7a and s7b, in order to use the pair of ladder ropes s7L and s7R for lateral offset and torsion suppression, it will be easily affected by the tilting action, but the slanting action of the slat s4 can be made Smooth, and can be erected in the vertical direction related to the suspension of the bottom rail s8 without burden. In addition, the horizontal blinds of the present embodiment are configured to attach the lifting ropes s6L, s6R suspended from the top box s1 to the upper surface of the bottom rail s8 provided below the plurality of slats s4. Thereby, the raising / lowering operation and the tilting operation of each slat s4 can be made smooth.

The present invention has been described above by exemplifying specific embodiments, but the present invention is not limited to the examples of the aforementioned embodiments, and various changes can be made without departing from the technical idea thereof. For example, the horizontal lines s7a and s7b crossing in an X shape are exemplified and described. However, the horizontal lines s7a and s7b may be parallel without crossing or may be one horizontal line.

In addition, the configuration may be such that two or more lifting ropes hang between the lifting ropes s6L and s6R, and at least one of the lifting ropes may hang down along the indoor side edge portion.
