Title: Blind structure

Description:
BACKGROUND OF THE INVENTION 
     a) Field of the Invention 
     The present invention relates to a blind structure, and more particularly to a blind that is provided with an effect of hiding cords. 
     b) Description of the Prior Art 
     A blind is currently used by every family or indoor space. The existing blind is mostly controlled by cords to expand or collect curtains. 
     Referring to  FIG. 1 , it shows a blind structure relative to a conventional curtain. Most blinds on an existing market will manifest a layered object hanging from top to bottom while being expanded vertically, as shown in  FIG. 1 . On the other hand, after being collected, the blind are parallel arranged piece by piece (not shown in the drawing). 
     However, as shown in  FIG. 1 , when being expanded, the blind manifests a layer and cords A thereof are provided behind the blind. Thus, when the blind is in use, the cords A will be suspended between blind B and a window (not shown in the drawing). Although the cords A are not exposed outside, as there is a distance between the blind B and the window, when a child is playing the blind, the child will be easily strangled by the cords A between the blind B and the window, resulting in a big hidden problem in a daily life of the child. In an actual society, it is often heard that a child was accidentally strangled by a cord of a blind, causing a regret that cannot be compensated. 
     SUMMARY OF THE INVENTION 
     Accordingly, the primary object of the present invention is to provide a blind structure that is provided with a better light shading effect and is able to hide the cords completely, allowing the blind to be used more safely. 
     To achieve the aforementioned object, the blind structure, according to the present invention, is constituted primarily by adhering plural soft materials. The blind is expanded and collected vertically by a cord and each soft material is in a loop shape. Each soft material is connected with the other using a binding agent between the two neighboring soft materials and in a place that the two neighboring soft materials are connected is provided with plural through-holes, allowing the cord to be transfixed into these through-holes. 
     Accordingly, the blind is expanded or collected vertically by the cord and when the loop-shaped soft materials are expanded, a double-layered blind effect can be achieved. Moreover, the cord can be contained completely in the soft materials, achieving an effect of hiding the cord completely, so as to provide a blind that is provided with a better light shading effect and can be used more safely. 
     To enable a further understanding of the said objectives and the technological methods of the invention herein, the brief description of the drawings below is followed by the detailed description of the preferred embodiments.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Referring to  FIG. 2 , it shows a three-dimensional schematic view of a blind structure of the present invention. As shown in the drawing, the blind structure  10  is constituted by interconnecting plural loop-shaped soft materials  11 ; the soft material  11  can be cloth. 
     Referring to  FIG. 2A  at a same time, it shows a blow-up diagram of a single blind structure of the present invention. As shown in the drawing, each soft material  11  is in a loop shape and is formed by looping a soft material  11  in a shape of a long stripe. Hence, each soft material  11  is formed with an opening  13 , and two sides of the opening  13  are pasted respectively with a binding agent  30 . In addition, the opening of each loop-shaped soft material  11  is provided with plural through-holes  12 , allowing at least a cord  20  to be transfixed into these through-holes  12 . 
     Referring to  FIG. 3 , it shows a partial schematic view of a first cross section of the blind structure of the present invention. As shown in the drawing, each soft material  11  is in a loop shape and an adhesive agent (not shown in the drawing) is applied between two neighboring soft materials  11 , allowing each soft material  11  to be interconnected. 
     Referring to  FIG. 3B  at a same time, it shows a partial exploded view at a circle in  FIG. 3 . As shown in the drawing, the soft material  11  of the present invention is formed primarily by looping a soft material  11  in a shape of a long stripe. As the soft material  11  is in a loop shape, when the blind structure is expanded, each soft material  11  will form a double-layered effect, thereby obtaining a better light shading effect. 
     Referring to  FIG. 4 , it shows a partial schematic view of a second cross section of the blind structure of the present invention. Referring to  FIG. 2A  at a same time, for the blind structure  10  of the present invention, plural through-holes  12  are provided between the two neighboring soft materials  11 , allowing the cord  20  to pass through these through-holes  12  to connect these soft materials  11 . A pitch of the through-holes  12  on each soft material  11  can be adjusted according to length of the soft material  11 . 
     Referring to  FIG. 4C  at a same time, it shows a blow-up diagram at a circle in  FIG. 4 . As shown in the drawing, as the soft material of the present invention is in a loop shape, when the through-holes  12  are provided between the two neighboring soft materials  11  that the cords  20  can pass through these through-holes  12 , the cords  20  will be hidden in the loop-shaped soft materials  11 . Therefore, when the blind structure  10  of the present invention is applied on a window (not shown in the drawing), the cords  20  will no longer be exposed between the blind structure  10  and the window. As a result, it can effectively avoid causing a child to be strangled accidentally, thereby providing a blind that is used more safely. 
     Referring to  FIG. 5 , it shows a schematic view of the blind structure of the present invention, after being collected. As shown in the drawing, as the cord  20  is transfixed between the two neighboring soft materials  11 , when the blind structure  10  is collected, the loop-shaped soft material  11  will be suspending at two sides of the cord  20  against the cord  20 , and manifest a state of stack. This can also increase aesthetics after the blind structure has been collected. 
     Referring to  FIG. 6 , it shows a perspective schematic view of a second embodiment of the present invention. The blind structure  10  of the present invention is formed by interconnecting plural loop-shaped soft materials  11 ; the soft material  11  can be cloth, paper or non-woven fabric. 
     Referring to  FIG. 7 , it shows a partial schematic view of a cross section of the second embodiment of the present invention. As shown in the drawing, each soft material  11  is in a loop shape and an adhesive agent (not shown in the drawing) is pasted between the two neighboring soft materials  11 , allowing the soft materials  11  to be interconnected. 
     Referring to  FIG. 7D , it shows a blow-up diagram at a circle in  FIG. 7 . As shown in the drawing, the soft material  11  of the present invention is formed primarily by looping a soft material  11  in a shape of a long stripe. As the soft material  11  is in a loop shape, when the blind structure of the present invention is expanded, each soft material  11  will form a double-layered effect, thereby achieving a better light shading effect. 
     It is worth of mentioning that as the blind structure  10  of the present invention is formed by interconnecting plural loop-shaped soft materials  11  with the adhesive agent, a non-seem effect will be formed on the entire blind structure  10  and no excessive connecting components will be needed. Moreover, each soft material  11  can be also manufactured into a different color, thereby achieving more color variations to increase a fun of using the blind. 
     In addition, in entire blind structure  10  of the present invention, locations of the through-holes  12 , the opening  13  and the cords  20 , in the loop-shaped soft materials  11 , are dependent upon the length and a draping property of the soft materials  11 . 
     It is of course to be understood that the embodiments described herein is merely illustrative of the principles of the invention and that a wide variety of modifications thereto may be effected by persons skilled in the art without departing from the spirit and scope of the invention as set forth in the following claims.
