Description

Combined curtain lower rail

The present invention relates to the undercarriage of a curtain, in particular, to a combined lower rail that can be easily assembled with a curtain fabric.

According to the general indoor space such as homes or offices, curtains are installed on the windows to block the sunlight or prevent outsiders from peeking, thereby reducing the indoor temperature or protecting privacy.

Curtains come in many forms. In the form of curtains, there is a type of curtain that winds up and down the curtain to cover the window, such as a roller blind or a roman shade, while the hem of the roller blind needs to be equipped with a lower rail weight to keep the roller blind upright. Naturally drooping, and the following rails are the center of gravity, increasing the stability of the roller blinds when winding up and down.

The conventional lower curtain rail has a longitudinal groove, and one side of the bottom edge of the curtain fabric is provided with a thin plastic strip, and the plastic strip of the curtain cloth is placed from one end of the groove of the lower rail, and then The plastic strip is inserted into the other end of the groove, so that the plastic strip is completely accommodated in the groove to complete the assembly of the curtain fabric and the lower rail. However, when the size of the curtain fabric is large, for example, six When the width of the ruler or the eight-footer is used, the length of the lower rail and the plastic strip also increases with the curtain fabric. Since the material of the plastic strip of the curtain fabric is soft, the plastic strip of the curtain fabric is inserted into the groove of the lower rail, and the length is long. It is difficult for the plastic strip to be smoothly inserted into the groove, and it is easy to be stuck to the inner wall surface of the groove, so that the plastic strip is difficult to be inserted from one end of the groove to the other end, which causes difficulty in assembly.

The main object of the present invention is to provide a combined lower curtain rail which can improve the convenience of assembling the curtain fabric and the lower rail and increase the speed of assembly.

The combined lower curtain rail of the present invention comprises: a left half body having a single cross-sectional shape, the cross-sectional structure comprising a first connecting mechanism disposed along the radial direction of the left half body on the left side The inner wall of the half body; a first card-incorporating mechanism is disposed at the lower end of the left half body, and includes a first locking portion and a first fitting groove, wherein the first locking portion is positioned higher than the first embedded portion The slot is spaced apart from each other; a first chamber is formed between the first locking portion and the first recess; a right half has a single cross-sectional shape, and the cross-sectional structure includes a second connecting mechanism The right half of the right half is disposed on the inner wall surface of the right half body and corresponds to the first connecting mechanism of the left half body; after the left half body and the right half body are combined, the first half of the left half body The connecting mechanism is connected to the second connecting mechanism of the right half; a receiving space is a space formed by the left half and the lower end of the right half, the first card-incorporating mechanism and the first chamber Is located in the accommodating space; an opening is located between the left half body and the lower end of the right half body, and is connected to the accommodating space; a receiving space is formed between the left half and the upper end of the right half; a port is located between the left half and the upper end of the right half, and communicates with the receiving space; a second card-in mechanism Provided on the upper end of the left half body, and having a second locking portion and a second recessed groove, the second locking portion is located lower than the second recessed groove; a second chamber is formed in the The second latching portion and the second recessed slot are located in the receiving space.

In this way, when the curtain fabric is assembled with the lower rail, the plastic strip of the curtain fabric is directly placed into the accommodating space of the left half body, and fixed by the first card-incorporating mechanism, and finally the left half body and the right half portion are fixed. The bodies are fastened to each other, and the curtain cloth and the lower rail are assembled, which greatly improves the assembly speed and convenience.
