Movable block set for curtain

Abstract

A removable block set for a window covering includes an inner block, an outer block and at least a connecting block between the inner block and the outer block. The inner block, the connecting block and the outer block are assembled together through the tenons and the slot tunnels therebetween, and the removable block set can be installed at two sections of the cases of the upper and the lower rails of the window covering. Therefore, through changing the whole length of the removable block set, the length of the upper and the lower rails (including the removable block set) may have a better conformation to the width of the window, and a more convenient installation of the window covering can be provided.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention is related to an improvement of removable block set for window covering, and more particularly to a removable block set capable of being mounted at respective two ends of an upper and a lower rails of a window covering for randomly changing the lengths of the rails, depending on a real demand as installing the window covering, through a partially detachable connected block set.[0003]2. Description of the Related Art[0004]In the market, the common window covering structure, such as Window covering, Pleated blind, mainly includes a set of upper rail and lower rail which are oppositely separated at the top and the bottom, foldable blinds mounted between the upper and the lower rails, and other components, such as pulling rope or remote controller, for controlling a folding or unfolding of the blinds so as to achieve light block or decoration.[0005]Furthermore, although many window coverings sold in th...

Benefits of technology

"The present invention provides an improvement of a removable block set for window covering. The user can easily match the upper and lower rails with the window through changing the length of the removable block set. The improvement includes an inner block, an outer block, and at least a connecting block between the inner and outer blocks. The inner block has an engaging space with a slot tunnel for engaging with the connecting block, and the connecting block has an engaging space with a slot tunnel for correspondingly engaging with the outer block. The length of the removable block set can be adjusted by changing the number of the connecting block. This invention provides convenience to the users for assembling the window covering by themselves."

Problems solved by technology

Furthermore, although many window coverings sold in the store need to be assembled and installed by the user himself at home, this kind of self-assembled window covering only provides several common standards so that even the user bought a window covering from the standards after measuring the real width of the windows, a discrepancy still might occur between the bought window covering and window when the user goes to install the window covering.

For example, tie width of the upper and the lower rails and of the blinds might be slightly wider than that of the window so that when installing, the user might need to cut the blinds for fitting in with the window; however, it is not easy to cut the tipper and the lower rails and a help from the professional workers might still need.

Therefore, it is quite inconvenient.

In addition, after the cutting, the whole structure of window covering, including the upper and the lower rails and the blinds, might be spoiled so as to influence the beauty of the house.
