Embodiment Construction

[0014] Referring to FIGS. 1-3, a drive device for a sunshade curtain of the present invention includes a motor 1, a driver 2, a pair of switches 3 and a housing 4. The motor 1 with two rotation directions has a driving shaft 11 which extending through a cover 12 attached to the housing 4. The driver 2 is fixed to the free end of the driving shaft 11. The pair of switches 3 is movably attached to the cover 12 at opposite sides of the driver 2. Each switch 3 is generally inverse L-shaped with a handle 31 at an end thereof projecting from the housing 4 and an idler 32 rotatably attached to the other end thereof. Both of the idlers 32 are in contact with the driver 2 at opposite sides of the driver 2. A pair of springs 33 are attached between the cover 12 and the switches 3 for providing resilience to the switches 3 to keep the idlers 33 in contact with the driver 2. The driver 2 has a concave peripheral surface 21 with a plurality of protrusions 22 extending therefrom.

Abstract

A drive device for a sunshade curtain includes a housing with a cover attached thereto, a motor received in the housing with a driving shaft extending through the cover, a driver attached to the free end of the driving shaft, and a pair of switches movably attached to the cover at opposite sides of the driver. The switches have a pair of idlers respectively in contact with the driver at opposite sides of the driver. When a rope for opening or closing the sunshade curtain is received between the driver and the idlers, and when the drive device is turned on to drive the driver, the rotating driver draws the rope to move along the rotation direction thereof through friction. Thus, the sunshade curtain is opened or closed automatically by the drive device through controlling the rotation of the motor.

Description

BACKGROUND OF THE INVENTION [0001] (a) Field of the Invention [0002] The present invention relates to a drive device, and particularly to a drive device for a sunshade curtain. [0003] (b) Description of the Prior Art [0004] In general, a sunshade curtain is opened or closed through drawing a rope formed with the sunshade curtain by hand. However, it is inconvenient to open or close the sunshade curtain by hand in some situations. Furthermore, it needs time and physical strength to open or close the sunshade curtain by hand. Thus, it is required to open or close a sunshade curtain automatically. SUMMARY OF THE INVENTION [0005] Accordingly, an object of the present invention is to provide a drive device for a sunshade curtain for automatically opening or closing the sunshade curtain. [0006] Further object of the present invention is to provide a drive device for a sunshade curtain which is convenient to open or close the sunshade curtain. [0007] To achieve the above-mentioned objects,...
