<First Embodiment>
FIG. 1 is a diagram showing a configuration of an electric roman shade device 1 according to the present embodiment. 1 (a) is a plan view of the electric roman shade device 1, FIG. 1 (b) is a front view, and FIG. 1 (c) is a side view. FIG. 2 is an enlarged view of the first pipe 5 of the Roman shade main body device 2. In this figure, the internal structure of a part of the first pipe 5 is shown so as to be understood. FIG. 3 is a side view of the Roman shade main body device 2. In the figure, the shade 3 is shown only in FIG. 3, and the shade 3 is omitted in the other figures.

As shown in the figure, the electric roman shade device 1 includes a roman shade main body device 2 and an aluminum angle 8 that fixes and supports the roman shade main body device 2 on a ceiling or the like.

The Roman shade main body device 2 includes an elevating cord 4 for suspending the shade 3, a first pipe 5 for winding the elevating cord 4, a second pipe 6, and a third pipe 7. Here, the lifting cords 4 are provided at five locations.

The shade upper end portion 3a of the shade 3 is attached to the aluminum angle front surface portion 8a with the shade fixing magic tape (registered trademark) 6x. The lifting string 4 is inserted in order from the insertion piece 22 on the upper end side of the shade 3, and the lower end is fixed to the insertion piece 22 located at the lowermost end.

Further, each of the lifting cords 4 is routed via a pulley block 95 attached to the aluminum angle 8 when it is wound around the first pipe 5, the second pipe 6, and the third pipe 7.

The first pipe 5, the second pipe 6, and the third pipe 7 are connected in this order from the right. These pipes (first pipe 5, second pipe 6, third pipe 7) are rotated by a motor 71 provided at an aluminum angle 8 at the right end portion in the drawing.

The diameters of the first pipe 5, the second pipe 6, and the third pipe 7 are the same. Regarding the length, the first pipe 5 is short and the second pipe 6 and the third pipe 7 have substantially the same length, but the length can be appropriately set.

The first pipe 5 is connected to the second pipe 6 by a limit bolt 53. The limit bolt 53 is screwed at a predetermined pitch. The second pipe 6 and the third pipe 7 are connected by an intermediate slide shaft 96. The intermediate slide shaft 96 is rotatably supported by the aluminum angle 8 by the support bracket 9d. At this time, as a structure capable of rotating, the support bracket 9d is provided with a resin bearing 94, and the intermediate slide shaft 96 is inserted through the resin bearing 94.

The third pipe 7 is an opposite end portion (left end portion in the drawing) of the second pipe 6 and is attached to the left end portion of the aluminum angle 8 via the end bracket 9c. Here, it is fixed by the end pipe slide shaft 97 at the left end of the third pipe 7.

Subsequently, the movement of the first pipe 5 accompanying the rotation of the motor 71 will be described mainly with reference to FIGS. 2 and 4. A motor 71 is fixed to an aluminum angle 8 via a motor bracket 9b on the right side portion of the Roman shade main body device 2.

The motor rotation shaft 71a of the motor 71 is provided with a slide shaft 71b extending inside the first pipe 5 and serving as an axis thereof. For example, a resin slide rotation shaft 77 is rotatably attached to the left end of the slide shaft 71b with the slide shaft 71b as an axis. That is, the slide rotation shaft 77 functions as a support portion that supports the first pipe 5, and transmits the rotation of the motor 71 to the first pipe 5.

The limit bolt 53 is fixed to the aluminum angle 8 by the bracket 9. A limit bolt receiving nut 91 (screw portion) is attached to the bracket 9, and the limit bolt 53 is screwed and screwed. That is, when the first pipe 5 rotates, the limit bolt 53 fixed to the first pipe 5 rotates.

At this time, since the limit bolt receiving nut 91 is fixed to the bracket 9, the first pipe 5 moves in a predetermined direction to the left and right as the limit bolt 53 rotates.

As a mechanism for controlling the amount of movement, a control mechanism based on the switch operation of the ring magnet and the reed switch is used. Specifically, the first reed switch 92 is attached to the illustrated right side of the base of the bracket 9, and the second reed switch 93 is attached to the left side.

A first ring magnet 82 is attached to a predetermined position of the limit bolt 53, here, the first ring magnet 82 is attached to the right side of the bracket 9 by the SL nut 82a, and the second ring magnet 83 is attached to the left side of the bracket 9 by the SL nut 83a. The first and second ring magnets 82 and 83 are fixed at desired positions by adjusting the positions of the SL nuts 82a and 83a, respectively.

The first and second reed switches 92 and 93 are connected to the motor 71 by a circuit wiring (not shown), and the operation of the motor 71 is controlled by a general control circuit.

Specifically, when the first reed switch 92 approaches the first ring magnet 82, the operation of the motor 71 that brings the first ring magnet 82 closer to the first reed switch 92 stops. Further, when the second reed switch 93 approaches the second ring magnet 83, the operation of the motor 71 that brings the second ring magnet 83 closer to the second reed switch 93 stops.

A more specific operation will be illustrated with reference to FIG. Here, FIG. 2 shows a state in which the first ring magnet 82 is close to the first reed switch 92. When the first pipe 5 is rotated by the motor 71 and the first pipe 5 moves to the left, the first ring magnet 82 approaches the first reed switch 92. As a result, the operation of the motor 71 is stopped. From the state of FIG. 2, when the first pipe 5 is moved to the right by the motor 71, the second ring magnet 83 moves so as to approach the second reed switch 93. When the second ring magnet 83 comes close to the second reed switch 93, the operation of the motor 71 is stopped thereby.

FIG. 4A shows a side view in a state where the slide rotation shaft 77 is arranged inside the first pipe 5, FIG. 4B shows a side view of the first pipe 5, and FIG. 4C shows a side view. The side view of the slide rotation shaft 77 is shown, and FIG. 4D shows the front view of the slide rotation shaft 77.

The first pipe 5 is, for example, a cylindrical pipe made of an aluminum alloy, and in cross-sectional view, fitting protrusions 55 having a predetermined height toward the center are provided at four locations, that is, 90 degrees, vertically and horizontally. It is formed at intervals. The fitting protrusion 55 is formed along the longitudinal direction of the first pipe 5 (the width direction of the electric Roman shade device 1).

The slide rotation shaft 77 is formed of a resin material in a substantially cylindrical shape, and a shaft shaft hole 77b is formed in the center thereof. The slide shaft 71b is inserted into and fixed to the shaft shaft hole 77b. Fitting grooves 77a are formed on the outer peripheral side surface of the slide rotation shaft 77 at intervals of 90 degrees in a cross-sectional view over the longitudinal direction.

When the slide rotation shaft 77 is arranged inside the first pipe 5, the fitting protrusion 55 engages with the fitting groove 77a. At this time, the slide rotation shaft 77 and the first pipe 5 are restricted from moving in the rotation direction of the motor 71 due to the engaging structure of the fitting groove 77a and the fitting protrusion 55, but move freely in the left-right direction. It is possible.

In this way, the first pipe 5 is rotated by the rotation of the motor 71 due to the support structure by the slide rotation shaft 77 and the screw structure of the limit bolt 53 and the limit bolt receiving nut 91. At that time, it moves to a predetermined left or right direction. The amount of movement is determined by the pitch of the limit bolt 53 and the amount of rotation of the limit bolt 53 (slide shaft 71b) by the motor 71.

The left end of the Roman shade main body device 2 is slidably supported along the axial direction by the end bracket 9c. That is, for example, the left end portion of the third pipe 7 can be freely moved in the left-right direction by means of an internal structure similar to the fitting structure of the first pipe 5 and the slide rotation shaft 77, a bearing, or the like.

As described above, according to the present embodiment, in the ascending / descending operation of the shade 3, the first pipe 5, the second pipe 6, and the third pipe 7 that wind up the elevating string 4 move to the left and right in conjunction with each other, so that the position is fixed. The lifting string 4 does not ride on itself on the pipe.

Further, since the lifting string 4 is wound around the pipes (first pipe 5, second pipe 6, third pipe 7) via the pulley block 95 attached to the aluminum angle 8, the shade 3 is opened to a higher position. Can be done. Since the roman shade has a curtain pool on the upper part, it is required to extend the lifting string 4 (fishing string) as far as possible to the upper part of the ceiling in order to increase the window area at the time of opening. However, the electric roman shade of the present embodiment is required. According to the device 1, such a request can be met.

Further, the contact between the shade 3 and a person and the influence of the wind can be absorbed without directly giving the winding portion between the lifting string 4 and the pipes (first pipe 5, second pipe 6, third pipe 7). .. That is, it is possible to suppress or prevent the shade 3 from being disturbed and the lifting string 4 from riding on. In particular, as a problem in use, when a person rolls up the shade 3 and looks out, the lifting string 4 may be wound up by riding on or disturbed, which may cause a failure. Since such a situation can be avoided, it is possible to respond to improvement requests from hotels, etc., where users change daily. Further, the removal / attachment work of the shade 3 at the time of washing can be easily performed without having to worry about the disorder of the lifting string 4.

Further, since the first and second ring magnets 82 and 83 are fixed by the SL nuts 82a and 83a, the fixing position can be easily adjusted. That is, it is easy to adjust / change the stop position such as winding up the lifting string 4.

Further, from the viewpoint of light leakage between shades due to continuous installation and cost, a mechanism capable of driving one large shade has been required, and such a demand can be met. Specifically, by supporting the pipes (first pipe 5, second pipe 6, third pipe 7) with a bracket 9, or the like, a plurality of short, small-diameter pipes can be used without bending. As a result, it becomes easy to connect and assemble at the construction site. In addition, since the storage space required for transportation and delivery can be narrowed, the range of construction can be expanded, such as the use of small transport vehicles and the use of elevators at construction sites. Can be done. That is, it is possible to install the electric roman shade device 1 using a wide range of single shades 3 even in places where conventional construction has not been possible.

In addition, it is easy to add pipes. FIG. 5 shows a modified example of the electric roman shade device 1A. The electric roman shade device 1A adds a roman shade main body device extension unit 2A to the above-mentioned roman shade main body device 2. The Roman shade main unit expansion unit 2A has an aluminum angle 8A different from the aluminum angle 8 to which the first pipe 5A, the second pipe 5B, and the third pipe 5C are attached as an expansion structure, and the fourth pipe 5D and the third pipe 5D. It is equipped with 5 pipes 5E.

The third pipe 5C and the fourth pipe 5D are connected by connecting slide shafts 98a and 98b extending from each of them. Further, the connecting slide shafts 98a and 98b are fixed and supported by the aluminum angles 8 and 8a by the support bracket 9d provided with the resin bearing 94, respectively.

In this way, since it is easy to add pipes, it is possible to respond to design changes at the construction site.
