Title: Binder having structure for punching document

Description:
TECHNICAL FIELD 
     Apparatuses consistent with the exemplary embodiments relate to a binder for binding documents and so on, and more particularly, to a binder having a structure for punching documents. 
     BACKGROUND ART 
     In general, a binder is one type of office supplies and is used to bind documents or photo albums. 
     A typical binder includes a cover and a filing device which is provided within the cover for binding documents. The filing device has a hinged structure and includes a plurality of fixing rings formed with an interval. While such a configured binder has to punch filing holes in targeted documents or papers to bind the documents or papers, the typical binder has no punch structure. Therefore, a separate puncher has to be used to punch the documents or the paper, which may result in cumbersomeness in using the binder. 
     DISCLOSURE 
     Technical Problem 
     To solve the above technical problems, one or more exemplary embodiments of the present invention provide a binder having a structure for punching filing holes in documents or papers. 
     Another exemplary embodiment is to provide a binder having a document punching structure optimally arranged to prevent documents to be bound from interfering in the document punching structure. 
     Technical Solution 
     The foregoing and/or other aspects may be achieved by providing a binder having a punching structure, including: a binder body which receives media therein and includes a cover part, a media binding part, and a central part which is formed to be bent with a predetermined width between the cover part and the media binding part; a fixing holder which is formed in the media binding part and binds the media; and a puncher which is positioned in the inside of the central part in such a manner that the puncher does not interfere in the media bound to the fixing holder, and punches filing holes in the media. 
     The puncher may includes: a punching base which is combined to the central part and has a cutter hole formed thereon; a lever member which is hinged to the punching base; a cutter which is formed in one side of the lever member at a position opposing the cutter hole of the punching base and punches the filing holes in the media; and an elastic member which elastically biases the lever member in one direction. 
     The puncher may includes: a punching base which is combined to the central part and has a cutter hole formed thereon; a lever member which is hinged to the punching base; a cutter holder which is provided to be isolated by a gap from the cutter hole of the punching base and has a cutter through hole formed at a position opposing the cutter hole of the punching base; a cutter which is provided to be elevatable in the cutter though hole and punches the filing holes in the media by virtue of a pressurizing force of the lever member; and an elastic member which elastically biases the cutter toward the lever member. 
     The cutter may include: a cutter body which is provided to be elevatable in the cutter through hole; and a cutter head which is formed in an end portion of the cutter body at the side of the lever member, and the elastic member may be interposed between the punching base. 
     The puncher may further include a stopper which projects from the punching base and restricts insertion depth of the media introduced between the punching base and the lever member. 
     A media fixing position of the fixing holder and a formation position of the cutter may have the same height in the binder body so as to punch new media to be bound in alignment with the media fixed by the fixing holder. 
     The puncher may further include a receiving member which is detachably combined to the bottom of the punching base and receives punching residues discharged via the cutter hole when the media are punched. 
     The fixing holder may include: a holder base which is formed in the media binding part; a filing device which is provided to be opened/closed in the holder base and is inserted in the filing holes of the media; and a handle member which is provided in the holder base and regulates the open/close of the filing device. 
     Advantageous Effects 
     According to an embodiment, since the binder having the punching structure is integrally formed with the puncher which punches the filing holes in the media, it is possible to avoid cumbersomeness such as providing a separate puncher to punch media to be bound. 
     According to an embodiment, since the puncher is arranged in the central part of the binder body and the fixing holder is arranged in the media binding part such that the puncher does not interfere in the media bound to the fixing holder, it is possible to prevent the media from being damaged by the puncher. 
     According to an embodiment, since the puncher is formed with a simple structure including the punching base, the lever member, the cutter and the elastic member, it is possible to minimize increase in production costs even if the punching structure is implemented in the binder.

     MODE FOR INVENTION 
     Below, binders having a punching structure according to exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. 
     In the following description and the attached claims, media received in a binder are intended to encompass all types of media formed with filing holes, including documents, papers, albums and the like. 
       FIGS. 1 and 2  are a perspective view and a side view showing a binder according to an exemplary embodiment of the present invention, respectively, and  FIG. 3  is a perspective view showing a fixing holder of the binder according to the exemplary embodiment of the present invention. 
     Referring to these figures, a binder according to an exemplary embodiment of the present invention includes a binder body  10  which receives media  1  having filing holes la punched therein, and a fixing holder  20  and a puncher  30  ( 130 ) which are formed in the binder body  10 . In this embodiment, the filing holes  1   a  may be formed in various ways, including a two-hole way, a three-hole way and the like, depending on the type of binder. 
     The binder body  10  includes a cover part  11 , a media binding part  13 , and a central part  15  which is formed to be bent with a predetermined width between the cover part  11  and the media binding part  13 . The central part  15  corresponds to a portion forming a binder width when the binder is folded, with the binder indexed in the outside of the central part  15 . 
     The fixing holder  20  is formed in the media binding part  13  and binds the media  1  through the filing holes  1   a  of the media  1 . 
     Referring to  FIGS. 2 and 3 , the fixing holder  20  includes a holder base  21  formed in the media binding part  13 , a filing device  23  having one openable end portion provided in the holder base  21 , and a handle member  25  which regulates the open of the filing device  23 . The filing device  23  is hinged to the holder base  21 . The filing device  23  may be elastically biased by an elastic piece provided in the holder base  21  in a direction regulated by the handle member  25 . Accordingly, when a pressurizing force by the handle member  25  is released, the filing device  23  can be rotated in a direction in which its end portion is opened. 
     The handle member  25  may include a rotating part  26  which is provided to be rotated with respect to a projecting piece  22  provided in the holder base  21 , and a rolling part  27  which rollably contacts one region  23   a  of the filing device  23 , as shown in  FIG. 4 . 
     Accordingly, referring to  FIG. 3 , when an end portion of the handle member  25  is lifted, the rotating part  26  is counterclockwise rotated to release the pressurizing force exerted on the filing device  23 . In this condition, the filing device  23  is rotated by the elastic piece  21   a  such that the end portion of the filing device  23  is opened. Under this condition, the filing device  23  is inserted in the filing holes  1   a  of the media  1 . 
     Then, by closing the end portion of the filing device  23  and pressing the handle member  25  to rotate the rotating part clockwise, the rolling part  27  presses the filing device  23  such that the filing device  23  remains closed. 
     When the binder is folded, between the fixing holder  20  and the central part  15  is formed a space A in which the puncher  30  ( 130 ) is positioned. That is, the puncher  30  ( 130 ) is positioned in the inside of the central part  15  of the binder body  10  in such a manner that the puncher  30  ( 130 ) does not interfere in the media  1  bound to the fixing holder  20 , and punches the filing holes  1   a  in the media  1 . 
     Referring to  FIGS. 4 and 5 , according to a first embodiment, the puncher  30  includes a punching base  31  which is combined to the central part  15  of the binder body  10  and has a cutter hole  31   a  formed thereon, a lever member  33  which is rotatably combined to the punching base  31 , a cutter  35  which punches the media  1 , and an elastic member  37 . 
     The lever member  33  is rotatably hinged to the punching base  31 . That is, the lever member  33  can be rotatably combined to the punching base  31  through a shaft  39 . The lever member  33  may include a reinforcing part  33   a  which is bent to reinforce the strength of the lever member, and a handle part  33   b  which is formed in an end portion of the lever member to facilitate rotation manipulation by a user. 
     The cutter  35  is formed in one side of the lever member  33  at a position opposing the cutter hole  31   a.  The cutter  35  punches the filing holes in the media  1  inserted on the punching base  31  while interlocking with the lever member  33  and going in and out of the cutter hole  31   a.  The number of cutter holes  31   a  and the number of cutters  35  may depend on the number of filing devices of the binder to which the puncher  30  is applied. For example, the numbers of filing devices  23 , cutter holes  31   a  and cutters  35  may be 3, respectively, for a binder for binding 3-hole media. The numbers of cutter holes  31   a  and cutters  35  of the puncher  30  are not limited thereto but may be modified in various ways. For example, a puncher for punching one filing hole at a time may be applied to a 3-hole binder. 
     The elastic member  37  elastically biases the lever member  33  in one direction. That is, the elastic member  37  provides an elastic force to restore the lever member  33  to a position in which the media can be inserted on the punching base  31  after the filing holes  1   a  are punched in the media  1  by the rotation of the lever member  33 . 
     The puncher  30  may further include a stopper  32  projecting from the punching base  31 . The stopper  32  restricts insertion depth of the media  1  introduced between the punching base  31  and the lever member  33  such that the filing holes are formed at a predetermined position in the depth direction. 
     In this invention, in forming the puncher in the binder body, a media fixing position of the fixing holder  20  and a formation position of the cutter  35  may have the same height in the binder body. More specifically, referring to  FIG. 1 , assuming that two filing devices  23  of the fixing holder  20  are formed and lines horizontally extending from the two filing devices  23  are L 1  and L 2 , respectively, the puncher  30  is provided in the central part  15  of the binder body  10  such that the cutter  35  is located on the lines L 1  and L 2 . By providing the fixing holder  20  and the puncher  30  in this manner, it is possible to punch new media to be bound in alignment with the media fixed by the fixing holder  20 . 
     Hereinafter, an operation of punching the filing holes  1   a  in the media  1  using the above-configured puncher  30  will be described. 
     Referring to  FIG. 5 , the puncher  30  has its one side opened by the elastic member  37  under no application of an external force. In this state, one or more media  1  to be punched are inserted on the punching base  31 . The insertion depth of the inserted media  1  is restricted by the stopper  32 . 
     When the lever member  33  is pressed toward the punching base  31 , the lever member  33  is rotated around the shaft  39  to descend the cutter  35 . The descended cutter  35  punches the media  1  as it penetrates through the media  1  and is inserted in the cutter hole  31   a.  Thereafter, when the pressurizing force exerted on the lever member  33  is released, the lever member  33  is rotated by resilience of the elastic member  37  and accordingly the cutter  35  is ascended to open the one side of the puncher  30  again. The above-described operation is repeated to punch the media  1 . 
     Referring to  FIG. 6 , in comparison with the puncher  30  according to the first embodiment, a puncher according to a second embodiment may further include a receiving member  41  which receives punching residues  3 . The receiving member  41  is detachably combined to the bottom of the punching base  31 . The receiving member  41  receives the punching residues  3  discharged via the cutter hole  31   a  when the media  1  are punched, thereby facilitating collection of the punching residues  3 . 
     Referring to  FIGS. 7 to 9 , according to a third embodiment, a puncher  130  includes a punching base  131  which is combined to a central part ( 15  in  FIG. 1 ) of a binder body and has a cutter hole  131   a  formed thereon, a lever member  133  which is rotatably combined to the punching base  31 , a cutter holder  135 , a cutter  137  which punches media  1 , and an elastic member  139 . 
     The lever member  133  is rotatably hinged to the punching base  131 . That is, the lever member  33  can be rotatably combined to a bracket  132  formed in the punching base  131  through a rotation pin  141 . 
     The lever member  133  may include a reinforcing part  133   a  which is bent to reinforce the strength of the lever member, a handle part  33   b  which is formed in an end portion of the lever member to facilitate rotation manipulation by a user, and a pressing part  133   c  which presses the cutter  137 . 
     The cutter holder  135  is provided to be isolated by a gap from the cutter hole  131   a  of the punching base  131 . A cutter through hole  135   a  is formed in the cutter holder  135  at a position opposing the cutter hole  131   a  of the punching base  131 . 
     The cutter  137  is provided to be elevatable in the cutter though hole  135   a.  The cutter  137  punches filing holes in the media  1  inserted on the punching base  31  while going in and out of the cutter hole  131   a  by virtue of a pressurizing force of the lever member  133 . To this end, the cutter  137  includes a cutter body  137   a  which is provided to be elevatable in the cutter through hole  135   a,  and a cutter head  137   b  formed in one end portion of the cutter body  137   a.  The cutter head  137   b  contacts the pressing part  133   c  formed in an end portion of the lever member  133  such that the cutter body  137   a  is ascended. The elastic member  139  is interposed between the punching base  131  and the cutter head  137   b  and the cutter body  137   a  is inserted into the elastic member  139 . 
     The number of cutter holes  131   a  and the number of cutters  135  may depend on the number of filing devices of the binder to which the puncher  130  is applied. For example, as shown in  FIG. 1 , the numbers of cutter holes  131   a  and cutters  135  may be 2, respectively, for a binder for binding 2-hole media. The numbers of cutter holes  131   a  and cutters  135  of the puncher  130  are not limited thereto but may be modified in various ways. 
     The puncher  130  may further include a stopper  131   b  projecting from the punching base  131 . The stopper  131   b  restricts insertion depth of the media  1  introduced between the punching base  131  and the lever member  133  such that the filing holes are formed at a predetermined position in the depth direction. In this embodiment, the puncher  130  may have a stopper groove  132   b  formed in the bracket  132 , independent of the stopper  131   b.    
     In this invention, in forming the puncher in the binder body, a media fixing position of the fixing holder ( 20  in  FIG. 1 ) and a formation position of the cutter  137  may have the same height in the binder body. 
     Hereinafter, an operation of punching the filing holes  1   a  in the media  1  using the above-configured puncher  130  will be described. 
     Referring to  FIG. 8 , the puncher  130  has its one side opened by the elastic member  139  under no application of an external force. In this state, one or more media  1  to be punched are inserted on the punching base  131 . The insertion depth of the inserted media  1  is restricted by the stopper  131   b  and the stopper groove  132   b  of the bracket  132 . 
     When the lever member  133  is pressed toward the punching base  131 , the lever member  133  is rotated around the shaft  39  to descend the cutter  137 , as shown in  FIG. 9 . The descended cutter  137  punches the media  1  as it penetrates through the media  1  and is inserted in the cutter hole  131   a.  Thereafter, when the pressurizing force exerted on the lever member  133  is released, the lever member  133  is rotated by resilience of the elastic member  139  and accordingly the cutter  137  is ascended to open the one side of the puncher  130  again. The above-described operation is repeated to punch the media  1 . In this embodiment, the puncher  130  may further include a receiving member (not shown) which receives punching residues  31 . 
     Although a few exemplary embodiments have been shown and described, it will be appreciated by those skilled in the art that changes may be made in these exemplary embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
