Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial application field The present invention relates to an electric roll screen.

(B) Conventional Technology As a conventional electric roll screen, for example, Japanese Unexamined Patent Publication
There is one disclosed in Japanese Patent No. 2-167982. The electric roll screen shown here is such that the winding pipe of the roll screen is driven by an ultrasonic motor. That is, the ultrasonic motor is fixed to the bracket supporting the winding pipe, and the winding pipe is connected so as to be rotationally driven by the ultrasonic motor directly or via an intermediate shaft.

(C) Problems to be Solved by the Invention However, in the conventional electric roll screen as described above, since the ultrasonic motor is arranged at one end side in the axial direction of the winding pipe, a space is provided on the side part of the roll screen. Is required, it is necessary to separately arrange a control device for controlling the ultrasonic motor and connect it to the ultrasonic motor, which is a troublesome wiring work. Since the motor is attached, the work of attaching the bracket to the window is troublesome and the workability is poor. That is, the ultrasonic motor can have a flatter structure than an ordinary motor and can be reduced in size in the rotation axis direction, but if it is arranged outside the bracket, a space is required for that amount. It will be. Therefore, the width of the screen becomes smaller than the width of the window frame. In addition, since the radial direction of the ultrasonic motor faces the vertical direction of the bracket, when the ultrasonic motor becomes large and the radial dimension becomes large, the bracket becomes large and the position of the winding pipe moves below the window, The screen stroke is smaller than the window,
Even if the screen is fully opened, the window cannot be completely opened. Further, although the above publication does not describe the disposition of the control device for controlling the ultrasonic motor at all, it is necessary to dispose it somewhere and also the connection between the control device and the ultrasonic motor is required. The purpose of the present invention is to solve such a problem.

(D) Means for Solving the Problems In the present invention, the ultrasonic motor and the control device are housed in a set frame provided on the upper part of the roll screen, and the ultrasonic motor and the winding pipe are connected via a gear. This solves the above problem. That is, the electric roll screen according to the present invention has a space (10a).
A set frame (10), a bracket (40) for fixing the set frame to a window frame or the like, and shaft support members (12, 14) provided so as to respectively hang from both ends of the set frame. A windup pipe (16) arranged below the set frame and rotatably supported at the lower end of the shaft support member, a screen (18) attached to the windup pipe, and the screen. A roll weight (20) attached to the lower end side of the set frame, and an ultrasonic motor (22) arranged in the space of the set frame such that their axial directions are aligned in the direction perpendicular to the longitudinal direction of the set frame, A control device (24) arranged in the space of the set frame for controlling the operation of the ultrasonic motor, and a rotary shaft (22a) of the ultrasonic motor penetrating the set frame. A driving gear (26) fixed so as to roll, and a driven gear (30) which is engaged with the driving gear and is arranged in parallel with the shaft supporting member so as to rotate integrally with the winding pipe. ,have. The reference numerals in parentheses indicate the corresponding members in the embodiments described later.

(E) Operation The set frame is placed above the take-up pipe, and the take-up pipe is attached to the shaft support member that hangs from both ends of the set frame. Since the take-up pipe can be attached to the bracket, it is not necessary to adjust the position of the bracket with respect to the window frame according to the axial dimension of the take-up pipe. Becomes extremely easy.

Further, since the ultrasonic motor and the control device can be arranged in this space part by utilizing the space part which the set frame has, it is not necessary to provide a space for disposing the ultrasonic motor and the control device in another place. It is not necessary to change the height position of the winding pipe to provide a space or to provide a space on the side portion of the shaft support member.

Furthermore, by arranging the axial direction of the ultrasonic motor so that it coincides with the direction perpendicular to the longitudinal direction of the set frame, the depth of the set frame increases even if the ultrasonic motor is upsized and the radial dimension is increased. So only
It does not affect the stroke of the screen.

In addition, since the ultrasonic motor and control device are placed in the space of the set frame in advance in a connected state, there is no need to install or wire the ultrasonic motor or control device at the construction site. It will be easier.

Further, since the mechanical device part and the electric device part in the set frame are assembled only by engaging the drive gear and the driven gear with each other and attaching the winding pipe to the shaft supporting member, the assembling work becomes easy. In addition, since the electrical components are arranged together, it is advantageous in terms of productivity and also facilitates repairs in case of failure.

(F) Example An example is shown in FIGS. As shown in FIG. 3, the electric roll screen includes a set frame 10 provided at an upper portion and shaft support members 12 and 14 arranged at both ends of the set frame 10.
And a winding pipe 16 rotatably supported by the shaft supporting members 12 and 14, and a screen 18 attached to the winding pipe 16. A weight bar 20 is attached to the lower end side of the screen 18.

As shown in FIG. 1, the set frame 10 has a hollow structure, and an ultrasonic motor 22 and a control device 24 are arranged in a space 10a thereof. The ultrasonic motor 22 is arranged so that its rotating shaft 22a is vertical, and a drive gear 26 is fixed to the rotating shaft 22a that penetrates the bottom surface of the set frame 10. The drive gear 26 meshes with a driven gear 30 provided so as to rotate integrally with the shaft 28 of the winding pipe 16. The drive gear 26 and the driven gear 30 are bevel gears, and are arranged so that their rotation axes are orthogonal to each other. axis
28 is rotatably supported by the shaft support member 12 via a bearing 32. The opposite end of the take-up pipe 16 is also rotatably supported by a bearing 36 fixed to the shaft support member 14, as shown in FIG. The set frame 10 is attached to a window frame or the like by two brackets 40 fixed to the window frame with screws 38.

Next, the operation of this embodiment will be described. By operating an operation switch (not shown), a current is supplied from the control device 24 to the ultrasonic motor 22, whereby the rotating shaft 22
a rotates, and this rotation is transmitted to the shaft 28 via the drive gear 26 and the driven gear 30, and the winding pipe 16 rotates. The screen 18 is wound or unwound by the rotation of the winding pipe 16. Winding and unwinding are switched by changing the rotation direction of the ultrasonic motor 22. Winding pipe
16 is a shaft support member 12 by a shaft 28 and a shaft 34 at both ends.
Also, because it is supported by the shaft support member 14, the ultrasonic motor
The weight of the take-up pipe 16 does not act on the take-up pipe 22, and the ultrasonic motor 22 transmits only the rotational force to the take-up pipe 16 via the drive gear 26 and the driven gear 30. Ultrasonic motor
Since the stationary torque of 22 is large, the falling of the screen 18 and the weight bar 20 due to its own weight is prevented only by the ultrasonic motor 22, and a latch mechanism or the like is unnecessary. Further, the gear ratio of the drive gear 26 and the driven gear 30 can be set as desired according to the weight of the screen 18 and the weight bar 20, the required winding speed, and the like. Since the ultrasonic motor 22 and the control device 24 are arranged in the space portion 10a of the set frame 10, the wiring work and the like are not necessary at the time of execution. Further, since the bracket 40 can be attached to the window frame and the set frame 10 can be fixed to the window frame, the attaching and removing operations are simple, and the ultrasonic motor 22 and the control device 24 can be repaired easily. It does not take.

Although the ultrasonic motor 22 is relatively weak to heat, it can be radiated through it by fixing it to the set frame 10, and in order to improve heat dissipation, the set frame 10 is provided with holes for ventilation. Alternatively, a forced ventilation device may be provided.

As shown in FIG. 1, at the end of the winding pipe 16,
Since only the driven gear 30 is provided in addition to the shaft support member 12, the space required on the side of the take-up pipe 16 is small, and the screen 18 having an appropriate width can be used for the window frame. . Also, when a large number of screens 18 are arranged side by side, it is not necessary to provide a large gap between them. Furthermore, since the rotary shaft 22a of the ultrasonic motor 22 is arranged so as to be perpendicular to the axial direction of the winding pipe 16, even if the ultrasonic motor 22 becomes large, the depth of the set frame 10 becomes large. Since it is only, it does not violate the stroke of the screen 18.

(G) Effect of the Invention As described above, according to the present invention, the set frame is arranged above the take-up pipe, and the take-up pipe is attached to the shaft support member hanging from both ends of the set frame to set the set-frame. Since the take-up pipe can be attached to the bracket simply by fixing the arbitrary position of the frame to the bracket, the installation work becomes extremely easy.
Further, since the ultrasonic motor and the control device may be arranged in the space portion of the set frame by utilizing the space portion, the height position of the winding pipe may be changed to provide a space or the shaft support member. There is no need to provide space on the side of the. Further, even if the ultrasonic motor is upsized, it does not affect the stroke of the screen.

Furthermore, the work of attaching or wiring the ultrasonic motor or the control device is not required at the construction site, which facilitates the construction.

Further, since the mechanical device part and the electric device part in the set frame are assembled only by engaging the drive gear and the driven gear with each other and attaching the winding pipe to the shaft supporting member, the assembling work becomes easy. Further, the length of the wiring between the ultrasonic motor and the control device can be made constant at all times. Even if the ultrasonic motor fails, it can be repaired separately from the roll screen body. At the time of production in a factory, the electric device part and the mechanical device part can be produced separately, so that the production efficiency is improved and the quality control is facilitated.
