Benefits of technology

The present invention provides a collapsible window blinds structure that can be easily collapsed and stacked to be bundled up into smaller volume without being restrained to wrap around the length of the conventional head rail, facilitating the carriage and the storage of the window blind thereof as well as saving the material of package to achieve the economical efficiency. The head rail assembly is made up of connection rods and linking elements reciprocally joined to each other, so the amount of the connection rods and the linking elements can be flexibly increased or reduced, depending on the size of the window frame or blind body without the head rail being individually tailor-made to fit to different window frames and blind bodies, economically saving the cost of production to boost the competitive power thereof on the market as well as to achieve unlimited versatile assembly thereof.

Problems solved by technology

There are some drawbacks to such conventional window blind structure.
Therefore, in package, the blind body 12 and the lift cord 14, determined by the size of the head rail 11, is restrained to wrap around the head rail 11 and bundle up into awkwardly bulky volume as shown in FIG. 2, which not only makes the storage thereof difficult to be done, but also increases the cost of package and carriage thereof.
Thus, the conventional window blind 10 is quite uneconomical and uncompetitive on the market.

Embodiment Construction

[0016] Please refer to FIG. 3 showing an exploded perspective view of the present invention. The present invention is related to a collapsible window blinds structure, comprising a blind body 20, a lift cord set 30, and a head rail assembly 40 wherein the blind body 20 has a fastening portion 21 made up of hook-side fasteners disposed at the top edge thereon, and a plurality of limiting hoops 22 evenly spaced and fixed in vertical lines at the rear side surface thereon. The lift cord set 30 is composed of lift cords 31, pulley seats 32 and a positioning pulley unit 33 wherein the lift cords 31 are guided through the limiting hoops 22 of the blind body 20 to wind around the pulley seats 32 and the positioning pulley unit 33 and fixed to the bottommost limiting hoops 22 thereof respectively. In this way, the blind body 20 is raised or lowered according to the collecting or expanding operation of the lift cords 31 thereby. The top edges of the pulley seats 32 and the positioning pulley...

Abstract

A collapible window blinds structure comprises a blind body, a lift cord set, and a head rail assembly wherein the blind body has a fastening portion at the top edge, and limiting hoops evenly spaced and fixed at the rear side surface for the running of lift cords there-through to wind around pulley seats and a positioning pulley unit respectively. The head rail assembly includes multiple connection rods and linking elements flexibly assembled according to the size of a widow frame. Each connection rod has a vertical thru-hole for the registration of a fitting portion of the pulley seats and the positioning pulley unit, and a fastened portion at a vertical side surface for the attachment of the fastening portion of the blind body thereto. Therefore, the head rail assembly and the blind body can be easily stacked and bundled up into smaller volume for convenient carriage and the storage.

Description

BACKGROUND OF THE INVENTION [0001] The present invention is related to a collapsible window blinds structure, comprising a blind body, a lift cord set, and a head rail assembly wherein the lift cord set guiding through the blind body is detachably mounted to the head rail assembly that can also be dismantled into separate pieces of connection rods and linking elements so that the head rail assembly and the blind body can be easily collapsed and stacked to be bundled up into smaller volume, facilitating the carriage and storage of the window blind as well as saving the material of package to achieve the economical efficiency thereof. [0002] Please refer to FIG. 1. A conventional window blinds structure includes a window blind 10 made up of a head rail 11 and a blind body 12 directly attached to the underside of the head rail 11 wherein the head rail 11 has a pulley seat 13 mounted at one end therein for the winding of a lift cord 14 to control the collecting or expanding operation of...
