  Hereinafter, several embodiments of the telescopic electric curtain rail of the present invention will be described with reference to an example shown in the drawings. In the drawings illustrating the embodiments, the same or corresponding constituent elements are denoted by the same or similar reference numerals. About the component which attached | subjected the same or similar code | symbol, the description about embodiment shown later which overlaps with description about embodiment shown previously may be abbreviate | omitted. In addition, in the case where a plurality of identical components exist in one drawing, only one of them may be given a reference numeral.

[1] Appearance Form FIG. 1 is a perspective view of an appearance form common to the embodiments of the telescopic electric curtain rail of the present invention, (a) showing a contraction form, and (b) showing an extension form. (C) shows a remote controller. Crossed arrows indicate the top, bottom, left and right in the figure.

  The telescopic electric curtain rail (hereinafter simply referred to as “curtain rail”) 1 can be expanded and contracted. The curtain rail body includes an outer rail portion 2 and an inner rail portion 3. In the contracted form of FIG. 1A, the inner rail portion 3 enters the inner side of the outer rail portion 2 so that the overall length of the curtain rail is the shortest. At this time, the length of the fitting portion (the portion overlapping each other) of the outer rail portion 2 and the inner rail portion 3 is the longest. The shortest contraction form of the curtain rail 1 is suitable for handling during transportation and sales.

  In the extended form of FIG. 1B, the entire length is extended by pulling out the inner rail portion 3 from the outer rail portion 2. The curtain rail 1 can be attached after adjusting to an appropriate length up to the upper limit length according to the length of the installation place such as the curtain box. When the length of the fitting portion between the outer rail portion 2 and the inner rail portion 3 is set to a minimum length that can ensure stable coupling, the total length of the curtain rail is the longest. In a general design example, the lengths of the outer rail portion 2 and the inner rail portion 3 are substantially the same. In that case, the shortest length is about one-half of the longest length.

  A part of two drive runners 4A, 4B and a plurality of driven runners 5A, 5B are suspended from a lower wall opening (not shown in FIG. 1) along the longitudinal direction of the lower wall of the outer rail part 2 and the inner rail part 3. I'm down. Each runner is formed with a hook hole for hanging a curtain hook.

  FIG. 1 shows a curtain rail for a double-open curtain composed of two left and right curtains. Therefore, the left curtain is suspended from the drive runner 4A and the driven runner 5A, and the right curtain is suspended from the drive runner 4B and the driven runner 5B. The drive runner 4 </ b> A is driven by the self-mounted electric motor and reciprocates inside the outer rail portion 2. The driven runner 5A on the left side of the drive runner 4A travels as the drive runner 4 travels. This opens and closes the right curtain. Similarly, the drive runner 4 </ b> B is driven by an electric motor mounted on the drive runner 4 </ b> B so as to reciprocate inside the inner rail portion 3. The driven runner 5B on the right side of the drive runner 4B travels according to the travel of the drive runner 4B. This opens and closes the right curtain.

  When the curtain is closed, the movements of the drive runners 4A and 4B are transmitted to the driven runners 5A and 5B via the suspended curtains, and the driven runners 5A and 5B move. When the curtain is opened, the driven runners 5A and 5B are moved by being pushed by the drive runners 4A and 4B.

  A drive control unit 6 also serving as an end cap is attached to the left end of the outer rail unit 2. An AC (Alternating Current) -DC (Direct Current) conversion adapter 61 converts AC 100 V taken from a household outlet into a DC voltage. The drive control unit 6 is supplied with a DC voltage and incorporates a wireless reception circuit, a control circuit, and the like which will be described later. The drive control unit 6 outputs power for driving the drive runners 4A and 4B.

  An electric motor (which may be a direct current motor or an alternating current motor) mounted on the drive runner is driven by the output of the drive control unit 6. The drive runner includes at least a pair of drive wheels, and the drive runner travels by transmitting the rotation of the electric motor to the drive wheels. The start and stop of travel of the drive runners 4A and 4B, the travel direction and the travel speed are controlled by the presence / absence, polarity and magnitude of the output voltage.

  The remote controller 8 illustrated in FIG. 1C transmits a control signal to the drive control unit 6 wirelessly. For example, a selection switch “R / L” for selecting one of the left and right curtains, a switch “O” for starting the curtain opening operation, a switch “C” for starting the curtain closing operation, and a switch for stopping the curtain operation “S” is provided.

  Another end cap 7 is attached to the right end portion of the inner rail portion 3.
