Benefits of technology

"The present invention provides a window blind that overcomes the drawbacks of prior art. The window blind comprises a shaft unit, a flexible screen body, a pair of bobbins, a pair of ropes, and a clutch unit. The shaft unit includes a seat member, a shaft member, a tubular member, and a pushing member. The screen body is wound on the tubular member. The bobbins are disposed on the shaft member and are securely rotatable on the shaft member. The ropes are wound on the bobbins and are coupled to the screen body. The clutch unit connects and disconnects the shaft member and the bobbins. The invention allows for easy operation and convenient use of the window blind."

Problems solved by technology

The conventional window blind is disadvantageous in that it is manually operated, which causes inconvenience on the part of the user.

Embodiment Construction

[0015]Referring to FIG. 1, the preferred embodiment of a window blind according to this invention is shown to include a pair of elongate slide rails 64, a shaft unit 4, a flexible screen body 61, a pair of bobbins 55, a pair of pulleys 63, a pair of ropes 65, and a clutch unit 54.

[0016]The window blind of this embodiment is applied to cover and uncover a sunroof (not shown), in a manner that will be described hereinafter.

[0017]Each of the slide rails 64 has opposite first and second rail ends 641, 642, and is formed with a rail groove 640 that extends from the first rail end 641 to the second rail end 642 of a respective one of the slide rails 64.

[0018]With further reference to FIG. 2, the shaft unit 4 includes a pair of seat members 41, a shaft member 43, a tubular member 42, and a pushing member 44. Each of the seat members 41 of the shaft unit 4 is disposed proximate to the first rail end 641 of a respective one of the slide rails 64. The shaft member 43 of the shaft unit 4 is mo...

Abstract

A window blind includes a shaft unit and a clutch unit. The shaft unit includes a pair of seat members, a shaft member, a tubular member, and a pushing member. The shaft member is mounted rotatably on the seat members. The tubular member is sleeved rotatably around the shaft member. The pushing member is sleeved securely on the shaft member. The clutch unit serves to connect and disconnect the shaft member and a pair of bobbins. When the shaft member is rotated in a first rotational direction, the clutch unit connects the shaft member and tubular member, thereby resulting in rotation of the tubular member in the first rotational direction. When the shaft member is rotated in a second rotational direction, the clutch unit disconnects the shaft member and the tubular member, and enables the pushing member to drive rotation of the tubular member in the second rotational direction.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The invention relates to a window blind, more particularly to an automated window blind.[0003]2. Description of the Related Art[0004]A conventional window blind for covering and uncovering a sunroof of an automobile includes a pair of seat members, a shaft member, a biasing spring, and a flexible screen body. The shaft member has opposite shaft end portions, each of which is mounted rotatably on a respective one of the seat members. The shaft member is rotatable relative to the seat members in a first rotational direction, and a second rotational direction opposite to the first rotational direction. The biasing spring serves to bias the shaft member in the second rotational direction. The screen body is wound on the shaft member.[0005]In operation, when it is desired to cover the sunroof, an external pulling force is applied to the screen body such that the screen body is pulled away from the shaft member, thereby resul...
