Description

The present invention relates to a cloaking device configured to enable a guide operation using an operation assisting tool.

A pleated screen, a honeycomb screen, and a horizontal blind are known as an example of a shielding device for raising and lowering a shielding material. Pleated screens and honeycomb screens are provided with a screen as a shielding material. The load of the screen located at the top position is transmitted to the elevating cord that suspends the screen. When the screen is gradually lowered, the load of the lowered screen is transferred from the elevating cord to the head box or the like. The horizontal blind is provided with a multi-stage slats as a shielding material. When the slats of each stage descend, the load of the descended slats is transferred from the elevating cord to the ladder cord or the like.

The rotational torque of the drive shaft that raises and lowers the shielding material decreases as the shielding material is lowered, as the load of the shielding material decreases. On the contrary, the rotational torque in the drive shaft increases as the shielding material is raised, as the load of the shielding material increases. Such a change in rotational torque on the drive shaft forces the user who drives the drive shaft to adjust the operating force. Therefore, in the above-mentioned shielding device, we propose a shielding device that is equipped with a constant load unit that applies a rotational torque that is almost equal to the load of the shielding material to the drive shaft in advance, and that can perform a guide operation that enables the shielding material to move up and down automatically. (See, for example, Patent Documents 1 and 2).

In the use of the shielding device described above, for example, the operation pole is inserted into the operation handle, and the operation is performed by operating the operation pole. Then, after the raising and lowering of the shielding material is completed, the operation pole is removed from the operation handle and left around the shielding device until the next operation. As a result, at the start of the next operation, the location of the operation pole is searched and the location of the operation pole is confirmed.
An object of the present invention is to provide a shielding device capable of improving the handleability of an operation assisting tool.

The shielding device for solving the above-mentioned problems is a shielding device that raises and lowers the shielding material by operating the rail using the operation assisting tool, and the operation is performed on the rail in a non-operating posture different from the operating posture. It is provided with a holding part for holding an auxiliary tool.

An embodiment of the cloaking device will be described with reference to FIGS. 1 to 22.
First, the overall configuration of the first pleated screen (see FIG. 1), which is an example of the shielding device, and the configuration of each operation handle (see FIGS. 2 to 11) will be described.

Next, the overall configuration of the second pleated screen (see FIG. 12), which is another example of the shielding device, and the configuration of each operation handle (see FIGS. 13 to 19) will be described. Subsequently, the overall configuration of the honeycomb screen (see FIG. 20), which is another example of the shielding device, and the configuration of the operation handle (see FIGS. 21 to 22) will be described.

The shielding device of each example raises and lowers the shielding material by operating the rail using the operation pole, which is an example of the operation assisting tool. The shielding device of each example includes a holding portion, and the holding portion holds the operation pole on the rail in a non-operating posture different from the operating posture.

[1st pleated screen]
As shown in FIG. 1, the pleated screen includes an upper screen 10 which is an example of a shielding material and a lower screen 20 which is an example of a shielding material. Further, the pleated screen includes a head box 100, an intermediate rail 11, and a bottom rail 21.

The screens 10 and 20 are bent in a zigzag shape in the vertical direction. The upper end of the upper screen 10 is connected to the headbox 100, and the lower end of the upper screen 10 is connected to the intermediate rail 11. The upper end of the lower screen 20 is connected to the intermediate rail 11, and the lower end of the lower screen 20 is connected to the bottom rail 21.

The intermediate handle 12 is an example of the holding portion, and is attached to the center of the intermediate rail 11 in the extending direction (left-right direction). The bottom handle 22 is an example of a holding portion, and is attached to the center of the bottom rail 21 in the extending direction (left-right direction).

The headbox 100 includes two drive shafts 101 arranged in the front-rear direction (one is shown in FIG. 1), two winding units 102, two gear units 103, and two constant load units 104. And prepare. Each drive shaft 101 has a polygonal columnar shape extending in the left-right direction.

Each take-up unit 102 winds up and unwinds the elevating cord 23 for each rail 11 and 21. Each of the elevating cords 13 and 23 is an example of a drive transmission member, and passes through the center of each of the screens 10 and 20 in the front-rear direction. Each gear unit 103 shifts the rotation of the drive shaft 101 and transmits it to the constant load unit 104. The constant load unit 104 outputs a constant load to the gear unit 103.

Here, the screens 10 and 20 and the rails 11 and 21 apply rotational torque to the drive shaft 101 through the elevating cords 13 and 23. The rotational torque due to this load acts in the unwinding direction on each drive shaft 101. On the other hand, the rotational torque output by the constant load unit 104 acts in the winding direction on each drive shaft 101. Then, the rotational torques of the drive shafts 101 are balanced, and the drive shafts 101 do not rotate due to the rotational torque due to the load, and remain stationary.

On the other hand, when the rails 11 and 21 are lifted, the rotational torque due to the load is temporarily reduced. As a result, the rotational torque of the constant load unit 104 is relatively increased, and the elevating cords 13 and 23 are wound up. Then, when the operating force is removed from the rails 11 and 21, the rotational torque on the drive shaft 101 is rebalanced and the rise of the rails 11 and 21 stops. When the rails 11 and 21 are pulled down, the elevating cords 13 and 23 are unwound. Then, when the operating force is removed from the rails 11 and 21, the rotational torques are rebalanced and the descent of the rails 11 and 21 stops. That is, the rails 11 and 21 move according to the guide operation in which the handles 12 and 22 are directly operated by hand or the operation using the operation pole 30, and the rails 11 and 21 are stationary in the state where the operation is completed.

[Each operation handle]
As shown in FIG. 2, the bottom handle 22 is an example of an operation handle, and includes a handle main body 221 and a guide operation lever 222 which is an example of a hanging portion. Further, the bottom handle 22 includes a pair of pole supports 223 on the left and right, a pair of first fixed claws 224 on the left and right, and a pair of second fixed claws 225 on the left and right.

The handle body 221 has a shape that follows the front surface, the lower surface surface, and the rear surface of the bottom rail 21. For example, the handle body 221 has a U-shape when viewed from the left-right direction. The width 2WB in the front-rear direction of the handle body 221 is substantially equal to the width in the front-rear direction of the bottom rail 21. The front upper end of the handle body 221 is integrated with the guide operation lever 222 and the first fixing claw 224. The rear upper end of the handle body 221 is integrated with the second fixing claw 225.

Further, the intermediate handle 12 includes a pair of pole supports 123 on the left and right, a pair of fixed claws 124 on the left and right, and a pair of fixed claws 125 on the left and right.

The handle body 121 has a shape that follows the front surface, the upper surface, and the lower surface of the intermediate rail 11. For example, the handle body 121 has an inverted U-shape when viewed from the left-right direction. The width 1WB in the front-rear direction of the handle body 121 is sufficiently smaller than the width in the front-rear direction of the intermediate rail 11 and larger than the width in the front-rear direction of the fixed claw 124. The front upper end of the handle body 121 is integrated with the guide operation lever 122 and the fixing claw 124. The rear lower end of the handle body 121 is integrated with the fixing claw 125.

The guide operation lever 122 has a plate shape protruding forward from the handle body 121 over the entire width of the handle body 121 in the left-right direction. The guide operation lever 122 includes a hook insertion hole 12H penetrating in the vertical direction. The hook insertion hole 12H is an elongated hole extending in the left-right direction, and is located at the center of the guide operation lever 122 in the left-right direction. The upper surface of the guide operating lever 122 is provided with a pair of left and right hook stoppers 12T. The pair of hook stoppers 12T are located in front of the hook insertion holes 12H. The pair of hook stoppers 12T are ridges extending in the front-rear direction, and are arranged at predetermined intervals in the left-right direction.

The pole supports 123 are located at both left and right ends of the handle body 121 and protrude forward from the handle body 121. The pole support 123 is located below the guide operating lever 122 and includes a support surface that is a flat upper end surface. The gap between the pair of pole supports 123 and the hook insertion hole 12H face each other in the vertical direction.

The support surface of the pole support 123 includes a pole stopper 126 that protrudes toward the guide operating lever 122. The pole stopper 126 is an example of a regulating protrusion. The lower surface of the guide operation lever 122 is provided with a pole stopper 127 at a position facing the pole stopper 126. The space between the guide operation lever 122 and the pair of left and right pole supports 123 is a holding space in which the operation pole 30 is held.

The fixing claw 124 has a cantilever shape protruding rearward from the guide operation lever 122. The pair of fixed claws 124 are located at both ends of the guide operation lever 222 in the left-right direction. The fixing claw 125 protrudes upward from the rear end of the handle body 121. The pair of fixed claws 125 are located at both ends of the handle body 121 in the left-right direction.

As shown in FIG. 4, the operation pole 30 includes a pole main body 31 and a hook 33 connected to the tip end portion 32 of the pole main body 31. The pole body 31 has a hexagonal columnar shape and has a shape that tapers at the tip portion 32. The hook 33 has an annular shape located in one plane.

[Action of operation handle]
As shown in FIG. 5, when the bottom handle 22 is attached to the bottom rail 21, a pair of left and right first fixing claws 224 are first hooked on the locking piece 21A of the front cover of the bottom rail 21. Next, the front end of the guide operating lever 222 is pushed down so that the pair of second fixing claws 225 on the left and right are lifted along the rear surface of the bottom rail 21. For example, by pushing down the fabric retainer 21B of the lower screen 20 on the bottom rail 21, the guide operation lever 222 is allowed to be pushed down.

During this time, the inner surface protrusion 228 of the handle body 221 and the lower surface corner portion of the bottom rail 21 are once in contact with each other, and the operator who pushes down the guide operation lever 222 is given a feeling of resistance due to the attachment. Then, when the operator increases the operating force so that the lower surface corner portion of the bottom rail 21 gets over the inner surface protrusion 228 of the handle body 221, the guide operating lever 222 is further pushed down.

As shown in FIG. 6, when the guide operation lever 222 is pushed down, the second fixed claw 225 is hooked on the bottom rail 21 while the first fixed claw 224 is hooked on the bottom rail 21. As a result, the bottom handle 22 is attached to the bottom rail 21 so that the bottom handle 22 wraps the bottom rail 21 from below. Then, in front of the bottom rail 21, the holding space sandwiched between the guide operation lever 222 (pole stop 227) and the pole support 223 (pole stop 226) is separated by the bottom handle 22.

As shown in FIG. 7, when the intermediate handle 12 is attached to the intermediate rail 11, a pair of left and right first fixing claws 124 are first hooked on the locking piece 11A of the front cover of the intermediate rail 11. Next, the front end of the guide operation lever 122 is pushed down so that the pair of second fixing claws 125 on the left and right are pushed along the lower surface of the intermediate rail 11. For example, by pushing down the fabric retainer 11B of the upper screen 10 on the intermediate rail 11, the guide operation lever 122 is allowed to be pushed down.

As shown in FIG. 8, as the push-down of the guide operation lever 122 progresses, the fabric retainer 11D of the lower screen 20 on the intermediate rail 11 is hooked on the intermediate rail 11 while the first fixed claw 124 is hooked on the intermediate rail 11. Pushed up by. As a result, the first fixing claw 124 is hooked on the locking piece 11A of the front cover of the intermediate rail 11, and the second fixing claw 125 is hooked on the locking piece 11C of the front cover of the intermediate rail 11. Then, the intermediate handle 12 is attached to the intermediate rail 11 so that the intermediate handle 12 wraps the intermediate rail 11 from the front. Further, on the front side of the intermediate rail 11, the holding space sandwiched between the guide operation lever 122 (pole stop 127) and the pole support 123 (pole stop 126) is separated by the intermediate handle 12.

Next, attachment and holding of the operation pole 30 will be described. Since the attachment and holding of the operation pole 30 to the bottom handle 22 and the attachment and holding of the operation pole 30 to the intermediate handle 12 are performed in the same procedure, the operation of the bottom handle 22 will be described below. The mounting and holding of the pole 30 will be described in detail.

As shown in FIG. 9, when the operation pole 30 is attached to the bottom handle 22, the hook 33 of the operation pole 30 is first inserted from below the guide operation lever 222 through between the pair of pole supports 223 on the left and right. It is inserted through the hole 22H. Next, the pole body 31 is turned so that the hook 33 having an annular shape does not come out of the hook insertion hole 22H.

As a result, the tip of the hook 33 is sandwiched between the pair of hook stoppers 22T, and the guide operation lever 222 is sandwiched between the tip portion 32 of the operation pole 30 and the hook 33. That is, the operation pole 30 is attached to the bottom handle 22 in a posture in which the pole body 31 is suspended from the guide operation lever 222. Then, the operation pole 30 is lifted or the operation pole 30 is pulled down, so that the bottom rail 21 is operated using the operation pole 30. When the bottom handle 22 reaches the reachable range, the operation by the operation pole 30 is completed, the pole body 31 is turned so that the hook 33 comes out of the hook insertion hole 22H, and the hook 33 is the hook insertion hole 22H. Is pulled out from.

As shown in FIG. 10, the operation pole 30 used for the operation abuts on the pole body 31 so that the extending direction of the operating pole 30 and the extending direction of the bottom rail 21 coincide with each other. It is pushed from the front of the bottom rail 21 toward the holding space. The pushed operation pole 30 is held by the bottom handle 22 in a posture in which the pole body 31 is supported from below by a pair of pole supports 223 on the left and right.

As shown in FIG. 11, the support surface of the pole support 223 comes into surface contact with one side surface of the hexagonal columnar pole body 31, thereby stabilizing the posture of the operating pole 30. Further, the pole stoppers 226 and 227 facing each other in the vertical direction come into contact with the pole main body 31, thereby preventing the pole main body 31 from falling out of the holding space. Then, the operation pole 30 is visibly placed horizontally in front of the bottom rail 21 as a posture when not operated. The guide operation lever 222 is located below the head box 100 and in front of the screen 20. The posture during operation is a posture in which the operation pole 30 attached to the intermediate handle 12 or the bottom handle 22 extends in the vertical direction. The non-operated posture is a posture other than the posture in which the operation pole 30 extends in the vertical direction.

According to the first pleated screen, the effects described below can be obtained.
(1) The operation pole 30 for operation is held by the handles 12 and 22 in a posture different from that at the time of non-operation. Therefore, when the operation using the operation pole 30 is performed, the operation pole 30 is taken out from the handles 12 and 22, and when the operation is completed, the operation pole 30 is held by the handles 12 and 22.

As a result, since each of the rails 11 and 21 to be operated can be set at the location of the operation pole 30 before, during, or after the operation, the handleability of the operation pole 30 can be improved. be. Since the posture of the operation pole 30 during operation and the posture of the operation pole 30 during non-operation are different from each other, the posture of the operation pole 30 during non-operation is specially shielded as described above. It is possible to set the changed posture.

(2) Since the extending direction of the operating pole 30 and the extending direction of the rails 11 and 21 coincide with each other while the operation pole 30 is held, the occupied space of the shielding device is expanded by holding the operation pole 30. Can be suppressed.

(3) The operation pole 30 is used in front of each of the rails 11 and 21, and the used operation pole 30 is held in front of each of the rails 11 and 21. Therefore, both the operation using the operation pole 30 and the holding of the operation pole 30 can be performed in front of the screens 10 and 20.

(4) Since each of the handles 12 and 22 holds the operation pole 30, the number of members of the pleated screen is increased as compared with the structure in which the structure for holding the operation pole 30 is separate from the handles 12 and 22. Can be suppressed.

(5) Since the operation pole 30 is hung at a position facing between the pair of pole supports 123 and 223 on the left and right, the pole supports 123 and 223 are used in the work of hanging the operation pole 30 on the guide operation levers 122 and 222. It becomes possible to suppress obstacles.

(6) The surface contact between the pole body 31 and the pole supports 123 and 223 stabilizes the posture of the operating pole 30 in holding. Therefore, the handleability of the operation pole 30 can be further improved.

(7) The contact between the pole body 31 and each pole stopper 226, 227 stabilizes the posture of the operating pole 30 in holding. Therefore, the handleability of the operation pole 30 can be further improved.

(8) Since the operation pole 30 held by the handles 12 and 22 is visible, it is possible for the user to know the location of the operation pole 30 before or after the operation.

[Second pleated screen]
The second pleated screen differs from the first pleated screen in the positions of the elevating cords 13 and 23 passed through the screens 10 and 20 and the configuration of the bottom rail 21 connected to the elevating cord 23. Hereinafter, the configuration different from that of the first pleated screen will be described in detail.

As shown in FIG. 12, the pleated screen includes an upper screen 10A which is an example of a shielding material and a lower screen 20A which is an example of a shielding material. Further, the pleated screen includes an intermediate rail 11P and a bottom rail 21P. Like the first pleated screen, the intermediate rail 11P has a rectangular shape extending in the front-rear direction when viewed from the left-right direction. Unlike the first pleated screen, the bottom rail 21P has a rectangular shape extending in the vertical direction when viewed from the left-right direction.

The intermediate handle 12A is an example of the holding portion, and is attached to the center of the intermediate rail 11P in the extending direction (left-right direction). The bottom handle 22A is an example of a holding portion, and is attached to the center of the bottom rail 21P in the extending direction (left-right direction).

The screens 10A and 20A are bent in a zigzag shape in the vertical direction. The elevating cords 13 and 23 pass through the joints at the rear folds of the screens 10A and 20A and are not visible from the front of the screens 10A and 20A. The bottom rail 21P is located directly below the elevating cords 13 and 23.

[Each handle]
As shown in FIG. 13, the bottom handle 22A has a handle body 221 and a guide operation lever 222, a pair of pole supports 223 on the left and right, a pair of first fixed claws 224 on the left and right, and a pair of second fixed claws 225 on the left and right. To prepare for. The handle body 221 has a shape that follows the front surface, the lower surface surface, and the rear surface of the bottom rail 21P, and has a U shape when viewed from the left-right direction.

The rear surface of the handle body 221 is provided with a pair of extending pieces 225A on the left and right. Each extension piece 225A has a cantilever shape protruding upward. The upper end of each extension piece 225A is integrated with the second fixing claw 225. The width 2WB in the front-rear direction of the handle body 221 is less than half the width in the front-rear direction of the screens 10A and 20A, and is sufficiently smaller than the width in the front-rear direction of the screens 10A and 20A.

As shown in FIG. 14, the intermediate handle 12A includes a handle body 121, a guide operation lever 122, a pair of pole supports 123 on the left and right, a pair of fixed claws 124 on the left and right, and a pair of fixed claws 125 on the left and right. The handle body 121 has a shape that follows the front surface, the upper surface, and the lower surface of the intermediate rail 11. The width of the fixed claw 124 in the front-rear direction is substantially equal to the width of the handle body 121 in the front-rear direction.

As shown in FIG. 15, when the bottom handle 22A is attached to the bottom rail 21P, first, a pair of left and right first fixing claws 224 are hooked on the locking piece 21A of the front cover of the bottom rail 21P. Next, the front end of the guide operation lever 222 is pushed down so that the pair of second fixing claws 225 on the left and right covers the upper surface of the bottom rail 21P from the rear. For example, by pushing the fabric retainer 21B of the lower screen 20 on the bottom rail 21P, the guide operation lever 222 is allowed to be pushed down.

As shown in FIG. 16, when the guide operation lever 222 is pushed down, the second fixed claw 225 is hooked on the upper surface of the bottom rail 21P while the first fixed claw 224 is hooked on the bottom rail 21P. As a result, the bottom handle 22A is attached to the bottom rail 21P so that the bottom handle 22A wraps the bottom rail 21P from below and behind. Then, on the front side of the bottom rail 21P, a holding space sandwiched between the guide operation lever 222 (pole stop 227) and the pole support 223 (pole stop 226) is separated by the bottom handle 22A.

As shown in FIG. 17, when the intermediate handle 12A is attached to the intermediate rail 11P, first, the intermediate rail 11P is inserted from the front surface between the first fixed claw 124 and the second fixed claw 125. At this time, the intermediate handle 12A is deformed so that the distance between the first fixed claw 124 and the second fixed claw 125 is widened, and the insertion of the intermediate rail 11P proceeds.

As shown in FIG. 18, as the insertion of the intermediate rail 11P progresses, the first fixed claw 124 is hooked on the locking piece 11A of the intermediate rail 11P, and the second fixed claw 125 is the locking piece of the intermediate rail 11P. It is hooked on 11C. As a result, the intermediate handle 12A is attached to the intermediate rail 11P so that the intermediate handle 12A wraps the intermediate rail 11P from the front. As a result, on the front side of the intermediate rail 11P, the holding space sandwiched between the guide operation lever 122 (pole stop 127) and the pole support 123 (pole stop 126) is separated by the intermediate handle 12A.

As an example of the operation for the bottom rail 21P, an operation for pulling down the bottom rail 21P from the state where the bottom rail 21P is pulled up to the uppermost position will be described.

Further, the bottom rail 21P has a rectangular cross section extending in the vertical direction and is suspended directly below the elevating cord 23. The center of gravity of the bottom rail 21P is substantially equal to the rear end portion of the lower screen 20A in the front-rear direction and is located behind the center C2 of the lower screen 20A. Since the bottom rail 21P has a shape extending in the vertical direction, the distance between the elevating cord 23 and the guide operation lever 222 can be further shortened in the front-rear direction as compared with the shape in which the bottom rail 21P extends in the left-right direction. .. Therefore, in the bottom rail 21P, the position where the operating force is transmitted and the position supported by the elevating cord 23 can be brought closer to each other in the front-rear direction.

The center C2 of the lower screen 20A in the front-rear direction is behind the center C1 of the headbox 100 in the front-rear direction. Further, the position of the elevating cord 23 in the front-rear direction is behind the center C2 of the lower screen 20A, and is at the rear end portion of the lower screen 20A (the joint SB at the rear crease in the lower screen 20A). be. That is, the elevating cord 23 is located behind the center C1 of the headbox 100 and behind the center C2 of the lower screen 20A in the front-rear direction.

Here, the periphery of the hook insertion hole 22H is a portion of the guide operating lever 222 where the operating force is transmitted from the operating pole 30. The hook insertion hole 22H is located behind the center C2 of the lower screen 20A or the elevating cord 23 in the front-rear direction. That is, the position of the hook insertion hole 22H and the position of the elevating cord 23 are both located behind the center C2. Therefore, in the bottom rail 21P, the position where the operating force is transmitted and the position supported by the elevating cord 23 can be further brought closer in the front-rear direction, and the operating force can be applied more smoothly. Become.

According to the second pleated screen, in addition to the effects according to the above (1) to (8), the effects described below can be obtained.
(9) The guide operation lever 222 is located below the lower screen 20 and overlaps the shielding range 20W in the front-rear direction. As a result, the operating force for pulling down the guide operating lever 222 does not act to pull out the lower screen 20A downward to the front side, but acts to pull down the lower screen 20A downward. Therefore, the operating force can be smoothly applied along the direction in which the elevating cord 23 is suspended.
(10) Further, since the guide operation lever 222 is included in the shielding range 20W in the front-rear direction, the effect according to the above (9) can be further enhanced.

(11) Since the bottom rail 21P has a rectangular cross section extending in the vertical direction, the guide operation lever 222 can be arranged in the shielding range 20W, that is, the configuration according to the above (9) can be embodied. It will be easy.

(12) Further, since the distance between the elevating cord 23 and the guide operation lever 222 can be shortened in the front-rear direction, the lower screen 20A can be pulled downward while maintaining the posture of the bottom rail 21P. Will be.

(13) Since the hook insertion hole 22H is located behind the center C2 of the lower screen 20A in the front-rear direction, the bottom rail 21P has a position where the operating force is transmitted and a position where the hook insertion hole 22H is supported by the elevating cord 23. It is possible to get closer in the front-back direction. Therefore, it is possible to further enhance the effect according to the above (12).
