Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application claims priority from Korean Patent Application No. 10-2015-0007577, filed on Jan. 15, 2015 and Korean Patent Application No. 10-2015-0190145 filed on Dec. 30, 2015, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference in its entirety. 
     TECHNICAL FIELD 
     The present disclosure relates to a connector for a blind-type curtain and a blind-type curtain comprising the same, and more particularly, to a connector for a blind-type curtain, which connects a plurality of curtain blinds to one another such that the curtain blinds can be individually separated for washing or replacement purpose and it is easy to control between light transmitting state and blackout state, and which has an extension plate configured to allow the curtain blinds to form a U-shape easily, and a blind-type curtain having the connector. 
     BACKGROUND ART 
     Curtains are draperies used for covering windows or doors. Such curtains may be generally categorized into a light transmitting curtain through which external light is passed, and a blackout type curtain by which external light is blocked. Since the curtains are categorized in the manner described above, it is inconvenient because a user has to select either of the light transmitting curtain or the blackout type curtain, and if the blackout type curtain is necessary while using the light transmitting curtain, the user has to remove the light transmitting curtain and arrange the blackout type curtain instead. 
     Blinds may be used instead of curtains to address the shortcomings mentioned above, in which case the user is able to control light transmitting state and the blackout state by adjusting an angle of rotation of the verticals. However, since the blind is made of a material different from the net material that is usually used for curtains, the user will not have the same effect as he or she is using curtains. There also is a problem that when the conventional curtains or blinds are contaminated or deformed, the user has to separate the entire curtains or blinds from the rail to wash, repair, or replace the same. 
     Accordingly, in order to address inconvenience of the user, curtain is necessary, in which it is possible to adjust the light transmitting state and the blackout state with only one curtain, and it is easy to wash, repair, or replace in the event contamination or deformation occurs.

     MODE FOR DISCLOSURE 
     Certain exemplary embodiments of the present inventive concept will now be described in greater detail with reference to the accompanying drawings. 
     However, the present disclosure is not limited to the exemplary embodiments described below, but may be implemented in a variety of forms different from each other. The exemplary embodiments are provided to complete the disclosure and to assist in a comprehensive understanding of the present inventive concept. In the following description, same drawing reference numerals are used for the same components even in different drawings. 
       FIG. 1  is a perspective view of a curtain blind according to a first exemplary embodiment of the present disclosure. 
     As illustrated in  FIG. 1 , a blind-type curtain according to a first exemplary embodiment includes a plurality of curtain blinds  100 , and connectors  200  for connecting a plurality of separate curtain blinds  100  to one another. 
     The curtain blind  100  is one unit set that constructs a blind-type curtain. In an exemplary embodiment, a plurality of such curtain blinds  100  may be used to construct a blind-type curtain. According to an exemplary embodiment, the curtain blind  100  includes a light transmitting curtain part  110 , and blackout curtain parts  120  provided on both sides of the light transmitting curtain part  110 , respectively. 
     The light transmitting curtain part  110  may be woven into a form of a net that allows external light to penetrate thereinto. The light transmitting curtain part  110  may be fabricated into a rectangular shape, and may be added with a variety of colors and patterns. Further, the light transmitting curtain parts  110  of a plurality of curtain blinds  100  may or may not have identical color or pattern, or these may have identical pattern and different colors, or identical color and different patterns. 
     The blackout curtain parts  120  may be provided on both sides of the light transmitting curtain part  110 . Accordingly, the light transmitting curtain part  110  together with the blackout curtain parts  120  construct one curtain blind  100 . The blackout curtain parts  120  include a first blackout curtain part  121  and a second blackout curtain part  122  provided on both sides of the light transmitting curtain part  110 , respectively. The blackout curtain parts  120  may have a greater thickness than the light transmitting curtain part  110  and thus provide a more blackout effect than the light transmitting curtain part  110 . However, according to an exemplary embodiment, the blackout curtain parts  120  do not completely shield the light as a general blackout curtain does. That is, the blackout curtain parts  120  may have a greater thickness than the light transmitting curtain part  110  so as to block the light slightly more than the light transmitting curtain part  110 . Of course, the exemplary embodiments are not limited to the example provided above. Accordingly, the blackout curtain parts  120  may be formed so as to completely block the light. Further, the blackout curtain parts  120  may preferably be fabricated into the same rectangular shape as the light transmitting curtain part  110 . The blackout curtain parts  120  may be separately fabricated and connected to the light transmitting curtain part  110 , although it would be more effective that the blackout curtain parts  120  are woven together with the light transmitting curtain part  110 . 
     The connectors  200  are provided to fasten adjacent blackout curtain parts  120  to each other. In an exemplary embodiment, fastening of the connectors  200  causes the light transmitting curtain part  110  to bend, whereby the curtain blind  100  has a U-shape. To this purpose, the connectors  200  include a first connector  210  provided at the first blackout curtain part  121 , and a second connector  220  provided at the second blackout curtain part  122 . Further, connecting rings are formed on upper sides of the connectors  200  to be engaged with the rail installed on ceiling, and so on. It is possible to control an angle of rotation of the curtain blind  100  by rotating via the connecting rings. Since the present disclosure relates to a curtain, it is of course possible that, like other general curtains, the blind-type curtain according to the exemplary embodiment may be open or closed in a lateral direction by moving the curtain blind  100  on the rail. 
       FIGS. 2 and 3  are perspective views of a connector for a blind-type curtain according to a first exemplary embodiment of the present disclosure. Further,  FIG. 4  is a perspective view of a first clip plate of a blind-type curtain according to a first exemplary embodiment of the present disclosure, and  FIG. 5  is a perspective view of a second clip plate of a blind-type curtain according to a first exemplary embodiment of the present disclosure. 
     Referring to  FIG. 2 , the connectors  200  are provided to fasten the curtain blind  100  to the rail, and the connectors  200  are fastened to upper portions of the blackout curtain parts  120  in a clip form. Further, the connectors  200  fastened to the upper portions of the blackout curtain parts  120  in clip form may be engaged with the rail through the connecting rings such that the curtain blind  100  is fastened to the rail via the connectors  200 .  FIG. 2  shows an example where the connector is coupled by the hook, in which case only one connecting ring is sufficient.  FIG. 3  shows an example where the hook is removed and the two connecting rings are connected to the rail ring  212 . 
     Referring to  FIGS. 4 and 5 , the connector  200  includes a clip plate  211  including a first clip plate contacting one surface of the upper portion of the blackout curtain parts  120 , and a second clip plate contacting the other surface of the upper portion of the blackout curtain parts  120 , and a connection ring formed on the upper portions of the first and second clip plates. Further, a rail ring  212  coupled to the rail is fastened to the connection ring such that the blackout curtain part  120  is fastened to the rail through the connector  200 . In an example, the rail ring  212  and the connecting ring are detachably attached. Further, at least one connector  200  may be fastened to the rail ring  212  through a connection ring. That is, although only one connection ring is illustrated as being connected to the rail ring  212  in the drawing, exemplary embodiments are not limited thereto, and accordingly, two or more connection rings may be connected to the rail ring  212  at a time. 
     Meanwhile, while  FIG. 5  shows only the hooks on the second clip plate for fastening with the first clip plate, the present disclosure is not limited thereto. Accordingly, the opposing surfaces of the first clip plate and the second clip plate may be provided with a plurality of projections such as spikes formed thereon to hold the blackout curtain parts  120  securely. 
     The first clip plate and the second clip plate respectively include a concave portion, and a convex portion having a diameter at a tip thereof that is greater than the diameter of the concave portion to be force-fit with each other, with the upper portion of the blackout curtain part  120  interposed therebetween. Further, at least one of the first clip plate and the second clip plate may have, on an outer side thereof, a concave portion or a convex portion having a diameter at a tip thereof that is greater than the diameter of the concave portion so as to fasten adjacent connectors  200  with each other. In an example, when the concave portion is formed on the outer side of the first clip plate, it is preferable that the convex portion is formed on the outer side of the second clip plate. 
     However, the present disclosure is not limited to the example provided above. Accordingly, it is also possible that adjacent connectors  200  are fastened to each other by the slits and the projections, instead of force-fitting by the concave and convex portions. 
       FIGS. 6 and 7  are perspective views showing a first connector for a blind-type curtain according to a modified example of the first embodiment of the present disclosure. 
     The first connector  210  may be attached to the upper portion of the first blackout curtain part  121 , and as shown in  FIG. 6A , one side of the slit may be open so that the second connector  220  may be fastened in a direction in which the slit is opened, or as shown in  FIG. 6B , the slits may have a different lateral diameter in certain part so that the second connector  220  is inserted into the corresponding slit part. However, the present disclosure is not limited to the example provided above. Accordingly, as shown in  FIGS. 7A and 7B , the vertical diameter of a certain part of the slits may be formed differently. 
       FIG. 8  is a perspective view of a second connector for a blind-type curtain according to a first exemplary embodiment of the present disclosure. 
     As shown in  FIG. 8 , the second connector  220  may have a projection having a large diameter at the tip thereof such that the corresponding projection may be fastened to the slit of the first connector  210 . 
     As described above, while it is exemplified herein that the blackout curtain parts  120  are fastened to each other by fastening of the projections and the slits, the present disclosure is not limited thereto. That is, a snap button, a Velcro tape, a magnet, a hook, or the like may be used for fastening of the blackout curtain parts  120 . That is, the present disclosure is not limited to any specific fastening structure as long as it can achieve the object of fastening the adjacent blackout curtain parts  120  to each other. 
     Meanwhile, in an exemplary embodiment, a weight may be additionally provided for promoting the aesthetic appeal of the curtain blind  100 . 
     The weight is provided at the lower end of the curtain blind  100  so that the curtain blind  100  is tightly pulled by the weight of the weight. Further, according to the present disclosure, the possibility that the curtain blind  100  is influenced by the wind can be minimized, and aesthetic appeal can be further increased. 
       FIG. 9  is a perspective view showing a curtain state of a blind-type curtain according to a first exemplary embodiment of the present disclosure, and  FIG. 10  is a top view of  FIG. 9 . 
     As shown in  FIGS. 9 and 10 , in an exemplary embodiment, a blind-type curtain is fabricated, including a plurality of curtain blinds  100  described above. Further, adjacent blackout curtain parts  122 ,  121 ′ of the curtain blind  100  are fastened to each other with a connector to thus form a U-shaped blind-type curtain as shown in  FIGS. 8 and 9 . Accordingly, the present disclosure can increase the aesthetic appeal of the blind-type curtain. 
       FIG. 11  is a perspective view illustrating a blind-type curtain in a blackout state according to a first exemplary embodiment of the present disclosure, and  FIG. 12  is a top view of  FIG. 11 . 
     As shown in  FIGS. 11 and 12 , according to an exemplary embodiment, the rotation of the curtain blind  100  causes the light transmitting curtain part  110  and the second blackout curtain part  122  of the curtain blind  100  to be overlapped with the first blackout curtain part  121 ′ of another curtain blind  100  adjacent thereto. Accordingly, the blind-type curtain according to the present disclosure is switched to a blackout state. 
     As described above, in some exemplary embodiments, when in a curtain state, the blind-type curtain may allow external light to be introduced into the room like a general curtain does, and when in a blackout state, the blind-type curtain may provide the same effect as a blackout curtain. 
     Meanwhile, in some exemplary embodiments, a plurality of curtain blinds described above are provided, and since they are separated from each other, washing and repair due to contamination or damage are easy. That is, what is needed is to separate the connector of the contaminated or damaged curtain blinds and separate only the contaminated or damaged curtain blinds from the rail, and then fasten the separated curtain blinds, which may have been washed or repaired, or newly purchased curtain blinds again with the connectors. Accordingly, it is easy to separate only the contaminated or damaged curtain blinds and wash or replace them. 
     Further, in some exemplary embodiments, by a structure in which a plurality of separate curtain blinds from each other are fastened to each other at the upper portions by means of connectors, only some curtain blinds are blown in the wind even when the wind blows, and a possibility that the entire curtain type blind is blowing in the wind can be prevented. 
     Further, the colors of the plurality of curtain blinds may be different from each other, or the patterns may be varied to promote the aesthetic appeal. That is, in some exemplary embodiments, one or more curtain blinds may be selected and applied according to the user&#39;s taste. 
     Next, a curtain blind according to a second exemplary embodiment of the present disclosure having an extension plate formed at a connector will be described with reference to the drawings. The elements or operations of the curtain blind that overlaps those already described above according to the first exemplary embodiment of the present disclosure will be omitted or described as brief as possible for the sake of brevity. 
       FIG. 13  is a perspective view of a curtain blind according to a second exemplary embodiment of the present disclosure. 
     As illustrated in  FIG. 13 , the blind-type curtain according to the second exemplary embodiment of the present disclosure includes a curtain blind  100 , and a connector  200  which connects a plurality of separate curtain blinds  100  and which has an extension plate formed thereon to support the light transmitting curtain part  110 . The curtain blind  100  will not be redundantly described below, as it is identical to that of the blind-type curtain according to the first embodiment of the present disclosure described above. 
       FIG. 14  is a perspective view of a connector for a blind-type curtain according to a second exemplary embodiment of the present disclosure. Further,  FIG. 15  is a perspective view showing a connector for a blind-type curtain being connected to a rail ring, according to a second exemplary embodiment of the present disclosure, and  FIG. 16  is a perspective view showing a connector for a blind-type curtain coupled according to a second exemplary embodiment of the present disclosure. 
     Referring to  FIGS. 13 and 14 , the connector  200  is fastened to the upper portion of the blackout curtain parts  120  in a clip form. Further, the connectors  200  fastened to the upper portions of the blackout curtain parts  120  in clip form may be engaged with the rail through the connecting rings such that the curtain blind  100  is fastened to the rail via the connectors  200 . 
     Referring to  FIGS. 14 to 16 , the connector  200  includes a first clip plate  210  contacting one surface of the upper portion of the blackout curtain parts  120 , and a second clip plate  220  contacting the other surface of the upper portion of the blackout curtain parts  120 . 
     The first clip plate  210  includes a first base plate  212  having a rectangular shape, a first extension plate  214  extending from one edge of the first base plate  212 , a hook protruding from one region of one surface of the first base plate  212 , and a spike  218  protruding from the other region of one surface of the first base plate  212 . 
     The first base plate  212  has a rectangular shape as described above, and is divided into a first base plate upper portion  212   b  as an upper region where the hook  216  is formed, and a first base plate lower portion  212   a  as a lower region where the spike  218  is formed. The first extension plate  214  is formed at one edge of the first base plate lower portion  212   a.    
     The first extension plate  214  extends from the first base plate  212  and supports the blackout curtain part  120  on the side surface of the first base plate  212 . According to some exemplary embodiments, the light transmitting curtain part  110  is curved by the fastening of the connector  200  so that the curtain blind  100  is formed into a U-shape, but when there is no first extension plate  214  at the connector  200 , the U-shape will not be formed properly. Accordingly, according to the present disclosure, an extension plate is formed on the base plate, and the first base plate lower portion  212   a  and the second base plate lower portion  222   a  are overlapped each other to support the blackout curtain parts  120 , and the first extension plate  214  and the second extension plate  224  support the light transmitting curtain part  110  so that the curtain blind  100  can easily be formed into a U-shape. 
     Meanwhile, although it is exemplified herein that the first extension plate  214  and the second extension plate  224  are extended on the first base plate  212  and the second base plate  222 , respectively, exemplary embodiments are not limited thereto. That is, an elastic member serving as an extension plate may be provided between the first base plate  212  and the second base plate  222  such that the light transmitting curtain part  110  may be more easily formed into a U-shape by the elastic bending. In an example, the elastic member has a shape in which the first base plate lower portion  212   a  and the first extension plate  214  are connected. Of course, only the first extension plate  214  extending from the first base plate lower portion  212   a  may be formed of an elastic member, or both the first extension plate  214  and the second extension plate  224  may be formed of an elastic member. 
     Further, in some exemplary embodiments, the lower edges of the first base plate  212  and the first extension plate  214 , and the second base plate  222  and the second extension plate  224  may be formed in a wavy shape, that is, in a continuous pattern of half circles such that wrinkling of the blackout curtain parts  120  at the boundary between the first clip plate  210  and the second clip plate  220  is prevented. 
     Meanwhile, in some exemplary embodiments, the first clip plate  210  and the second clip plate  220  may have the fastening structure as shown in  FIGS. 6 to 8 . 
       FIGS. 17 to 27  are perspective views showing a connector for a blind-type curtain coupled according to a modified example of the second exemplary embodiment of the present disclosure. 
     Meanwhile, in some exemplary embodiments, a modified form of a connector for a blind-type curtain may be provided, as shown in  FIGS. 17 to 27 . This may include the edge of the connector  200  rounded as shown in  FIG. 17 , or the edge of the connector  200  chamfered as shown in  FIG. 18 . Further, the modified form may include the edge of the connector  200  formed into a stepped shape as shown in  FIG. 19 , or both edges of the connector  200  angled as shown in  FIG. 20 . Further, the modified form may include rounded one edge of the connector  200  and angled other edge of the connector  200 , as shown in  FIG. 21 . Of course, as shown in  FIGS. 22 to 27 , in the above-described modified examples, the connection ring may be formed on the second base plate upper portion  222   b  without protruding upward. 
       FIG. 28  is a perspective view illustrating a curtain state of a blind-type curtain according to a second exemplary embodiment of the present disclosure, and  FIG. 29  is a top view of  FIG. 28 . 
     As shown in  FIG. 9 , the related blind-type curtain does not properly maintain the U-shape, whereas in the exemplary embodiment of the present disclosure as shown in  FIGS. 28 and 29 , a perfect U-shaped blind-type curtain is formed in which the adjacent blackout curtain parts  122 ,  121 ′ of the curtain blind  100  are fastened to each other with the connector. Accordingly, in some exemplary embodiments, the aesthetic appeal of the blind-type curtain can be further increased. 
       FIG. 30  is a top view illustrating a blind-type curtain in a blackout state according to a second exemplary embodiment of the present disclosure.
