Description
- The present invention relates to blinds and, more specifically, to a battery-operated electric blind, which enables the user to replace the battery conveniently.
- A regular electric Venetian blind, as shown in FIG. 1, comprises a
headrail 1 defining a holding chamber, abottom rail 2, a plurality ofslats 3 arranged in parallel between theheadrail 1 and thebottom rail 2, apower drive 4 installed in the holding chamber of theheadrail 1. Thepower drive 4 comprises a transmission mechanism 5, a reversible motor 6, and abattery 7. The transmission mechanism 5 is coupled to thebottom rail 2 and/or theslats 3 by an amplitude modulation lift cord or frequency modulation lift cord. The motor 6 is coupled to the transmission mechanism 5. Thebattery 7 is electrically connected to the motor 6 to provide the motor 6 with the necessary working voltage, for enabling the motor 6 to drive the transmission mechanism 5 in lifting thebottom rail 2 and theslats 3, or tilting theslats 3. Due to limited service life, thebattery 7, either dry type or storage type, must be replaced when battery power was low. However, because thebattery 7 is mounted inside the holding chamber of theheadrail 1 behind its front sidewall, it is difficult to access to thebattery 7. When replacing thebattery 7, the user has to insert the hand through the top open side of theheadrail 1 to pick up thebattery 7. If theheadrail 1 is directly attached to theceiling 8 and stopped against thepilaster 9, the user must detach or tilt theheadrail 1 from theceiling 8 when replacing thebattery 7. - The present invention has been accomplished under the circumstances in view. It is therefore the main object of the present invention to provide a battery-operated electric blind, which enables the user to detach the battery for a replacement conveniently.
- To achieve this object of the present invention, the battery-operated electric blind comprises a headrail having an outer frame surface and an inner frame surface defining a holding chamber, a slat set, and a power drive installed in the holding chamber of the headrail and coupled to the slat set. The outer frame surface of the headrail is provided with a battery chamber adapted for holding a battery which is electrically connected to the power drive. The battery chamber has an opening extended to the outside of the headrail through which the battery is inserted into the battery chamber.
