TWO-WAY ELEVATING CURTAIN STRUCTURE

BACKGROUND OF INVENTION

1. Field of the Invention

The present invention relates generally to a two-way elevating curtain structure, and more particularly to a two-way elevating curtain structure that works smoother and controls more stably.

2. Description of Related Art

The conventional blind closes or opens the curtain for shades starts from the bottom of the curtain, however, because the sunlight reflects into the house in different angles depending on the time and outdoor object.

Therefore, to shade the sunlight at certain angle, it must lower the most of the curtain to shade, such may cause the indoor and outdoor air fail to circulate, which stops the lighter sunlight from coming into the house, and create poor circulation in the house and insufficient light.

To solve the disadvantages created from the conventional blind mentioned above, the industry developed a structure that elevates in two-ways. In addition to closing and opening the blind up and down from the bottom of the curtain, the top of the curtain can also come down to the bottom of the curtain, or the bottom being drawn up to the fixed curtain rod, it controls the entire positions of the curtain (not just from the bottom of the curtain) going up and down, and keep out the sunlight that is at different angle without stopping the circulation and natural outdoor sunlight. This improved curtain can solve the disadvantage of the conventional curtain, however, to control the bottom or top of the curtain to go up and down, the instrument used still has the disadvantages of interference and disruptive movement, therefore, it is necessary to improve the structural design.

Thus, to overcome the aforementioned problems of the prior art, it would be an advancement if the art to provide an improved structure that can significantly improve the efficacy.

To this end, the inventor has provided the present invention of practicability after deliberate design and evaluation based on years of experience in the production, development and design of related products.

SUI24ARY OF THE INVENTION The installation of the control structure 50, which uses the first/second roll-up cord shaft 51 52 to operate the bottom 43 and top 41 of the cord fabric to go up and down independently, therefore, during the operation, it will not be stuck because of the interference; also because the first/second roll-up cord shaft 51 52 are wrapped by the pull strings 11 12 13 14, therefore, the wrapping movement is more stable because the support of the first/second roll-up cord shaft 51 52, which makes the operation of the two-way curtain more smooth and stable.

Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.

DETAILED DESCRIPTION OF THE INVENTION

The features and the advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of a preferred embodiment of the present invention with reference to the accompanying drawings.

As shown in FIGS. 1-2, a preferred embodiment of the present invention, comprising: a fixed curtain rod 10, which uses the pull strings 11 12 13 14 of the first/second controlling component 20 30 on both sides, and move the cord fabric 40 up and down (same as the conventional components, therefore, it is not stated here in detail), the improved feature of the present invention is: the control structure 50, which includes the first/second roll-up cord shaft 51 52 that is placed on the shaft 10 inside the fixed curtain rod 10, which makes one end of the first/second roll-up cord shaft 51 52 to connect to the first/second controlling components 20 30, so that when the controlling cords 21 31 of the first/second controlling components 20 30 are pulled down, it drives the controlled component 20 30 to the first/second roll-up cord shaft 51 52 in the clock and counter clock wise; moreover, the first roll-up cord shaft 51 is wrapped by the pull strings 11 12, and one end of the pull strings 11 12 go through the fixed curtain rod 10, and through the top 41 of the cord fabric 40, and the cloth cover 42 that is connected to the bottom 43, and the second roll-up cord shaft 52 is wrapped around by the pull strings 13 14, and one end of the pull strings 13 14 goes through the fixed curtain rod 10 and being secured to the top 41 of the cord fabric 40.

As shown in FIGS. 2 and 3, when the bottom 43 of the cord fabric 40 must go up to close the cloth cover 42, the controlling cord 21 of the first control component 20 is pulled down to move the pull strings 11 12 of the first roll-up cord shaft 51 up and pull the bottom 43 up to close the cloth cover 42.

As shown in FIGS. 2 and 4, when the top 41 of the cord fabric 40 must be pulled down to the bottom 43, the controlling cord 31 of the second control component 30 is pulled down to move the pull strings 13 14 of the second roll-up cord shaft 52 down, and pull the top 41 down to the cloth cover 42.

As shown in FIG. 5, which is the first/second controlling component 20 30 that can be placed on both sides of the surface of the fixed curtain rod 10 (the first control component 20 is disclosed here for

description), so that the first/second controlling

component 20 30 is placed on the surface of the fixed curtain rod 10 in 90-degree angel, and uses one end of the first/second roll-up cord shaft 51 2 to connect to the bevel gear 511, and locks in with the bevel gear 201 of the first/second controlling components 20 30, so that the first and second controlling components would not be unable to use because of the wall, and further makes the assembly easy and convenient to operate.

As shown in FIG. 6, the present invention is also applicable for Roman curtain 60.

As shown in FIG. 7, when the width of the cord fabric is larger, a third set of pull strings 15 16 can also be added to the first/second roll-up cord shaft 51 52, and connected to the top 41 of the cord fabric 40, cloth cover 42 and bottom 43 to make the opening and closing operation

more stable.
