Benefits of technology

[0005]Therefore, the object of the present invention is to provide a blind device having a screen body that can be furled and unfurled, and a counterweight unit with components that can be removed from the screen body or folded relative to the screen body to reduce packaging material and storage space requirements of the blind device.

Problems solved by technology

Since the counterweight unit of the conventional blind device is provided fixedly on the screen body and is not foldable, packaging material and storage space requirements of the conventional blind device are large.

Abstract

A blind device includes a flexible screen body with interconnected shielding sections, and a counterweight unit provided on a lowermost one of the shielding sections. The counterweight unit includes vertically extending left and right side bars provided respectively at left and right edges of the lowermost shielding section, and a horizontally extending bottom bar retained at a bottom edge of the lowermost shielding section. The counterweight unit is convertible from a screen-stretching state, where the lowermost shielding section is stretched by the side bars, to a screen-foldable state, where folding of the lowermost shielding section in a vertical direction is permitted by the counterweight unit.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The invention relates to a blind device, more particularly to a blind device having a screen body that can be furled and unfurled.[0003]2. Description of the Related Art[0004]A conventional blind device includes a flexible screen body that can be furled and unfurled, and a counterweight unit provided on the screen body to balance the winding force of a winding mechanism. Since the counterweight unit of the conventional blind device is provided fixedly on the screen body and is not foldable, packaging material and storage space requirements of the conventional blind device are large.SUMMARY OF THE INVENTION[0005]Therefore, the object of the present invention is to provide a blind device having a screen body that can be furled and unfurled, and a counterweight unit with components that can be removed from the screen body or folded relative to the screen body to reduce packaging material and storage space requirements of t...
