Further, a plurality of elevating cords 10 are hung from the head box 1 alongside the ladder cord 2 on the outdoor side or the indoor side, and a bottom rail 4 is attached to one end of the elevating cord 10.

In the horizontal blind of the present embodiment, the tilt drum 51 for suspending the pair of front and rear ladder cords 2 and the winding drum 52 for winding or rewinding the elevating cord 10 are rotatably supported. Members 5 are arranged on both the left and right sides of the head box 1 and in the center thereof.

Further, the drive shaft 11 is inserted into the tilt drum 51 and the take-up drum 52 of each support member 5 so as not to rotate relative to each other.

When the drive shaft 11 is rotated, the tilt drum 51 is rotated, and the angles of the multi-stage slats 3 suspended and supported by the ladder cord 2 are adjusted. Further, when the drive shaft 11 is rotated, the angles of the multi-stage slats 3 are tilted in a direction substantially perpendicular to the horizontal direction, and then the elevating cord 10 is wound or rewound by the take-up pipe 52. This is done, and the slats 3 can be raised and lowered by raising and lowering the bottom rail 4.

An operation device 7 for operating the rotation of the drive shaft 11 by the operation code 77 is arranged on the right end side of the head box 1, which will be described in detail later with reference to FIGS. 2 and 3. Then, the operation code 77 is configured to be automatically hoistable in the operation device 7. The lower end of the operation code 77 is inserted into the operation rod 8 which is suspended and supported so as to be slidable in the left-right direction with respect to the operation device 7, and then attached to the operation knob 9.

Therefore, the hoisting force is always exerted on the operation code 77 by the operation device 7, and the operation knob 9 is always in contact with the lower end of the operation rod 8 when the operation knob 9 is not operated.

Further, a brake device 12 capable of locking the rotation of the drive shaft 11 is provided in the head box 1.

Hereinafter, the configuration and operation of the operation device 7 of the present embodiment will be described more specifically.

(Operating device)
FIG. 2 is a perspective view showing a schematic configuration of an operating device 7 in a horizontal blind according to an embodiment of the present invention. Further, FIG. 3 is an exploded perspective view showing a schematic configuration of the operating device 7.

First, referring to FIG. 2, the operating device 7 includes a carrier 72, a pair of output bevel gears 73a and 73b, an input bevel gear 74, a reel 75, a one-way clutch 76, an operation code 77, a mainspring case 78, and a mainspring 79. It is housed by the lower case 70 shown by the solid line and the upper case 71 shown by the broken line. Further, the lower end of the operation code 77 is inserted into the operation rod 8 which is suspended and supported so as to be slidable in the left-right direction with respect to the operation device 7, and then attached to the operation knob 9.

Subsequently, the structure of the operating device 7 will be described with reference to FIG. Since the shape of the upper case 71 can be substantially the same as that of the lower case 70, the description will be mainly based on the lower case 70 in the following description, and the illustration of the upper case 71 is omitted in FIG. There is.

Each of the pair of output bevel gears 73a and 73b has the same shape as each other, but each has a tooth portion 731 having tooth streaks formed obliquely with respect to the rotation shaft 732. A square hole 733 for inserting the square rod-shaped drive shaft 11 into the rotating shaft 732 protruding from both sides of the tooth portion 731 in each of the pair of output bevel gears 73a and 73b in a short length and a long length, respectively, is provided. It is provided.

Each of the pair of output bevel gears 73a and 73b is arranged so that the tips of the rotating shafts 732 protruding long are in contact with each other and facing each other as shown in FIG. , It is rotatably supported by the support walls 702 and 703 in the lower case 70 shown in FIG. As a result, when each of the pair of output bevel gears 73a and 73b is accommodated by the lower case 70 and the upper case 71 so that the drive shaft 11 is inserted into each rotating shaft 732 and faces each other, the pair of output bevel gears 73a and 73b are moved back and forth, left and right, and vertically. It is rotatably supported by the support walls 702 and 703 without rattling. As shown in FIG. 3, in the lower case 70 (the same applies to the upper case 71), a round recess 704 is formed in the corresponding wall portion in order to avoid interference with the drive shaft 11.

The input bevel gear 74 is formed with a tooth portion 741 that can mesh with the tooth portions 731 of the pair of output bevel gears 73a and 73b. A rotating shaft 742 that projects shortly is formed from both sides of the tooth portion 741 of the input bevel gear 74, and a fitting shaft 743 extends from one of the rotating shafts 742 as shown in FIG. Each rotating shaft 742 that projects shortly from both sides of the input bevel gear 74 is rotatably supported by a pair of support walls 721 and 722 that stand upright from the plate-shaped portion 720 of the carrier 72. It is preferable to provide a member for holding the support from above so that the input bevel gear 74 does not separate from the pair of support walls 721 and 722 of the carrier 72 (not shown).

The one-way clutch 76 has a double drum structure of an outer drum 761 and an inner drum 762, and when the outer drum 761 rotates clockwise in the figure, the inner drum 762 is also transmitted to rotate without delay, but the outer drum 761 The inner drum 762 does not rotate when it rotates counterclockwise in the figure, and the outer drum 761 idles (relatively rotates) with respect to the inner drum 762 so that the rotation is not transmitted.

Then, the fitting shaft 743 extending from one of the rotating shafts 742 of the input bevel gear 74 is fitted into the fitting shaft hole 763 of the inner drum 762 in the one-way clutch 76 so as not to rotate relative to each other.

The one-way clutch 76 is accommodated in the hollow portion 751a provided in the rotating shaft 751 of the reel 75, and the outer peripheral wall of the outer drum 761 in the one-way clutch 76 is relative to the peripheral wall of the hollow portion 751a. It is fixed so that it cannot rotate relative to each other.

Therefore, when the reel 75 rotates clockwise in the drawing, the input bevel gear 74 is also transmitted to rotate without delay, but when the reel 75 rotates counterclockwise in the drawing, the input bevel gear 74 does not rotate.

As shown in FIG. 3, the reel 75 is configured to wind up the operation code 77 having one end attached to the rotating shaft 751 when rotating counterclockwise in the drawing and rewinding when rotating clockwise in the drawing. A pair of discs 752 having a diameter corresponding to the winding amount of the operation code 77 are formed on the rotating shaft 751. As described above, a cavity 751a for accommodating the one-way clutch 76 and fixing the outer peripheral wall of the outer drum 761 is formed on one side surface of the reel 75, but the other side surface of the reel 75 is formed. The round shaft 753 protrudes from the. The round shaft 753 is rotatably inserted and supported through a through hole 783a provided in the center of the support shaft 783 protruding from the round tubular main body 781 of the mainspring case 78. A notch 753a for locking one end 791 of the mainspring 79 is formed on the round shaft 753.

In the mainspring case 78, a housing portion 781a for accommodating almost the entire mainspring 79 is formed in the round tubular main body portion 781, and a notch 781b for locking the other end 792 of the mainspring 79 is formed. ing. Then, the round shaft 753 of the reel 75 is inserted and supported by the through hole 783a provided in the center of the support shaft 783 of the mainspring case 78 so as to be relatively rotatable, and one end 791 of the mainspring 79 is engaged in the notch 753a. When the mainspring case 78 is stopped and the other end 792 of the mainspring 79 is locked to the notch 781b of the main body 781 in the mainspring case 78, an urging force is always generated in the direction of winding the operation cord 77. There is.

The support shaft 783 protruding from the round tubular main body portion 781 of the mainspring case 78 is supported by a support wall 723 that stands upright from the plate-shaped portion 720 of the carrier 72.

Therefore, the input bevel gear 74, the reel 75, the one-way clutch 76, the mainspring case 78, and the mainspring 79 are directly or indirectly supported by the carrier 72.

In this example, the plate-shaped portion 720 of the carrier 72 is formed with a fixing hole 725 for fixing the upper end of the hexagonal tubular operating rod 8 from below, and one end is attached to the rotating shaft 751 of the reel 75. The other end of the operation cord 77 to be hung down is inserted into the operation rod 8 fixed to the fixing hole 725, and then attached to the operation knob 9.

Further, a round leg 724 is formed at an appropriate position on the lower surface of the plate-shaped portion 720 of the carrier 72, and is placed on the bottom portion 701 of the lower case 70. At this time, the bottom 701 of the lower case 70 (the same applies to the upper case 71) is connected to the round hole-shaped through holes 707a and 707b sufficiently larger than the hexagonal maximum diameter of the operation rod 8. A 707 is formed, and when the operating rod 8 is inserted through the through hole 707a or 707b, the operating rod 8 narrowly presses between the through hole 707a and the through hole 707b to allow movement.

The plate-shaped portion 720 of the carrier 72 is accommodated by the side wall and the support wall 702,703,705 around the lower case 70 without rattling back and forth.

On the other hand, a pair of square rods 782 are formed in the left-right direction on the main body portion 781 of the mainspring case 78. The pair of square rods 782 are supported by the support wall 705 in the lower case 70 (the same applies to the upper case 71) shown in FIG. 3 so as to allow sliding in the left-right direction, and the main body 781 is also supported by the lower case 70 (upper case 71). The case 71 is also supported by the support wall 706 in the case 71) so as to allow sliding in the left-right direction. The mainspring case 78 is supported by the lower case 70 and the upper case 71 (not shown) so that the mainspring case 78 can slide in the left-right direction but cannot rotate relative to each other. As a result, the carrier 72 is accommodated without rattling in the front-rear and up-down directions, and only sliding in the left-right direction is allowed.

Further, in a state where the operating rod 8 is located in the through hole 707a and the plate-shaped portion 720 of the carrier 72 is placed on the bottom portion 701 of the lower case 70, the tooth portion 741 of the input bevel gear 74 is the tooth of the output bevel gear 73a. It meshes with the portion 731, but does not mesh with the tooth portion 731 of the output bevel gear 73b.

Similarly, when the operating rod 8 is located in the through hole 707b and the plate-shaped portion 720 of the carrier 72 is placed on the bottom portion 701 of the lower case 70, the tooth portion 741 of the input bevel gear 74 is the tooth of the output bevel gear 73b. It meshes with the portion 731, but does not mesh with the tooth portion 731 of the output bevel gear 73a.

As a result, the carrier 72 can be moved in the same direction by sliding the operation rod 8 in the left-right direction, and the meshing of the tooth portions 741 of the input bevel gear 74 can be switched to one of the tooth portions 731 of the output bevel gears 73a and 73b. Since the operating rod 8 is made movable by narrowing the pressure between the through hole 707a and the through hole 707b, the state can be stabilized when the operating rod 8 is located in the through hole 707a (or 707b). At the same time, it is possible to give a click feeling to the operation related to the switching.

FIG. 4A is a plan view of the operating device 7 when the operating rod 8 is located in the through hole 707b, and is a plan view of the operating device 7 when the operating rod 8 is located in the through hole 707a. It is shown in 4 (b).

As shown in FIG. 4A, a case where the operation rod 8 is slid to the right in the operation device 7 is shown, and this state is referred to as a “right operation end”. Is located in the through hole 707b and the carrier 72 is slid to the right (white arrow). Then, the input bevel gear 74, the reel 75, the one-way clutch 76, the mainspring case 78, and the mainspring 79 mounted on the carrier 72 are located relatively to the right with respect to the lower case 70, and the tooth portion 741 of the input bevel gear 74 is located. Engages with the tooth portion 731 of the output bevel gear 73b, but does not mesh with the tooth portion 731 of the output bevel gear 73a.

Therefore, as shown in FIG. 4A, when the operation rod 8 is slid to the right operation end in the operation device 7 and then the reel 75 is rotated in the direction of the arrow shown by the operation code 77, the drive shaft is driven. 11 is transmitted to rotate in the direction of the arrow (reverse rotation) shown in the figure.

Similarly, as shown in FIG. 4B, the operation device 7 shows a case where the operation rod 8 is slid to the left, and this state is referred to as a “left operation end”. The operating rod 8 is located in the through hole 707a, and the carrier 72 is slid to the left (white arrow). Then, the input bevel gear 74, the reel 75, the one-way clutch 76, the mainspring case 78, and the mainspring 79 mounted on the carrier 72 are located relatively to the left with respect to the lower case 70, and the tooth portion 741 of the input bevel gear 74 is located. Engages with the tooth portion 731 of the output bevel gear 73a, but does not mesh with the tooth portion 731 of the output bevel gear 73b.

Therefore, as shown in FIG. 4B, when the operation rod 8 is slid to the left operation end in the operation device 7 and then the reel 75 is rotated in the direction of the arrow shown by the operation code 77, the drive shaft is driven. 11 is transmitted to rotate in the direction of the arrow (forward rotation) shown in the figure.

As described above, in the operation device 7 of the present embodiment, depending on whether the operation rod 8 is slid to the left operation end or the right operation end, the drive shaft 11 can be operated only by pulling out the operation code 77. The direction of rotation can be switched.

Further, when the operation knob 9 is released after the operation code 77 is pulled out by using the operation knob 9, the operation code 77 is automatically wound up by the reel 75 in the operation device 7, so that the operation knob 9 is not operated. It will be constantly located at the lower end of the operating rod 8.

(Overall operation)
Next, with reference to FIGS. 5 and 6, the overall operation of the horizontal blind according to the present invention will be described.

5 (a) to 5 (d) show a series of operations from the lowering operation in the horizontal blind of the present embodiment to the horizontal state of the slat 3 at the lower limit of the bottom rail 4.

From the state where the bottom rail 4 is located above and the slats 3 are folded, slide the operation rod 8 to the left operation end as shown in FIG. 5A, and then use the operation knob 9. By pulling out the operation code 77, the bottom rail 4 can be lowered while the slats 3 are tilted fully closed.

Subsequently, as shown in FIG. 5B, with the bottom rail 4 reaching a predetermined position (lower limit position in the illustrated example), the operation knob 9 is released while the slats 3 are tilted fully closed. Then, the operation code 77 is automatically wound up until the operation knob 9 is located at the lower end of the operation rod 8.

Subsequently, as shown in FIG. 5C, with the slats 3 tilted fully closed, the operation rod 8 is slid to the right operation end, and then the operation code 77 is operated by using the operation knob 9. By performing the pull-out operation, the angle of the slats 3 can be adjusted to an arbitrary angle (horizontal in the illustrated example).

Subsequently, as shown in FIG. 5D, when the operation knob 9 is released while the slats 3 are at an arbitrary angle (horizontal in the illustrated example), the operation knob 9 is positioned at the lower end of the operation rod 8. The operation code 77 is automatically wound up to.

Subsequently, FIGS. 6A to 6D show a series of operations from the horizontal state to raising the bottom rail 4 and the slats 3 at the lower limit in the horizontal blind of the present embodiment, respectively.

FIG. 6A shows a state in which the slat 3 is in a horizontal state and the operation rod 8 is positioned at the right operation end.

From the state shown in FIG. 6A, as shown in FIG. 6B, by pulling out the operation code 77 using the operation knob 9 with the operation rod 8 at the right operation end, the slats The angle of 3 can be adjusted in the opposite direction to an arbitrary angle (in the illustrated example, the state of being tilted to the reverse fully closed position).

Subsequently, as shown in FIG. 6C, for example, when the operation knob 9 is released while the slats 3 are tilted to the reverse fully closed position, the operation code is until the operation knob 9 is located at the lower end of the operation rod 8. 77 is automatically wound up.

Subsequently, as shown in FIG. 6D, the slats 3 are tilted to the reverse fully closed state by pulling out the operation code 77 using the operation knob 9 with the operation rod 8 at the right operation end. The bottom rail 4 can be raised in the same state.

As described above, according to the horizontal blind and its operation device 7 of the present embodiment, when the slats 3 are raised and lowered and the angle is adjusted by one drive shaft 11, a conventional endless operation code is used. The operation is easier to understand than the operation, and the operability can be improved.

Further, according to the horizontal blind and the operation device 7 thereof of the present embodiment, the safety can be enhanced because the loop shape is not formed unlike the conventional configuration using the endless operation cord.

Although the present invention has been described above with reference to examples of specific embodiments, the present invention is not limited to the examples of the above-described embodiments, and various modifications can be made without departing from the technical idea. For example, in the example of the above-described embodiment, an example in which the operation rod 8 is suspended and supported from the operation device 7 in front of the horizontal blind and the operation rod 8 is slid in the left-right direction to switch the rotation direction of the drive shaft 11 has been described. However, such a slide direction does not have to be limited to the left-right direction. For example, the operation device 7 is arranged in front of or to the side of the horizontal blind, and the operation rod 8 is configured to switch the rotation direction of the drive shaft 11 by sliding in the front-rear direction or by sliding in a curved or V-shaped manner. Is also possible.

Therefore, slides that move the carrier 72 relative to the lower case 70 include linear, curvilinear, and V-shaped slides.

Further, in the above-described example of the embodiment, the bevel gear has been described as an example for the rotation transmission of the input / output, but the gear mechanism constituting the rotation transmission of the input / output can be appropriately selected, and it is not necessary to limit the gear mechanism. However, by adopting the bevel gear, the size of the operating device can be easily reduced.

Further, in the example of the above-described embodiment, an example of a horizontal blind that mainly raises and lowers the slats and adjusts the angle with one drive shaft has been described, but any shielding device that requires such operation of the drive shaft in the rotational direction , Not limited to horizontal blinds, it can also be applied to pleated screens, roman shades, vertical blinds, roll screens, and the like.

According to the present invention, since an operating device with improved operability and safety can be configured, it is useful for applications of a shielding device that requires operation in the rotation direction of the drive shaft.
