Definitions

  • the present invention relates to a binder used to form a booklet by bundling end portions of a plurality of sheets of paper.
  • a booklet such as a notebook and a book is formed by end portions of a plurality of sheets of paper being bound by means of glue, a thread, or the like.
  • a user may form a booklet by binding a plurality of sheets of paper in order to classify and organize documents or the like as needed.
  • so-called ring files and the like have been often used in such a case.
  • a ring file is provided with a front cover folded in half and an annular fastening tool as holding means for holding a plurality of sheets of paper on the back surface of the front cover, a through hole in a document is formed by means of a punch or the like, the annular fastening tool is inserted through the through hole, and then paper can be added or removed as needed.
  • a binder that is illustrated in Patent Literature 1 includes a long cover member disposed along the spine portion of a front cover and the cover member is provided with a clip as holding means.
  • This clip is a technique known in the related art as illustrated in Patent Literature 2.
  • the clip of Patent Literature 2 is formed by an elastic and metallic thin plate being folded and is formed in a substantially U shape in side view and so as to open in the front cover direction with a pair of facing holding pieces extending from the short-direction end portion of a base portion.
  • the pair of holding pieces are formed so as to spread ahead in the opening direction.
  • pressing claws facing each other are respectively formed so as to be folded inward to the base portion side.
  • the bundle of a plurality of sheets of paper is slid and pushed into a pressing member having a U shape in side view with the bundle of a plurality of sheets of paper inserted between the pair of holding pieces of the clip.
  • the pair of holding pieces are pinched in the pressing member and the sheet bundle can be strongly pressed by the return elastic force of the pair of pressing claws compressed between the holding piece and the sheet bundle.
  • the sheet bundle and the pressing member may be respectively grasped and pulled in a direction of separation.
  • the pressing claws of the clip are respectively pressed against the front surface of the paper on the uppermost surface and the back surface of the paper on the lowermost surface against which the pressing claws of the clip directly abut. Then, the frictional force that acts on the point of mutual abutment prevents the front and back surfaces of the sheet bundle from moving relative to each other.
  • the sliding of the opening inner surface of the pressing member and the surface of the holding piece of the clip causes the pressing member and the clip to operate so as to be relatively separated from each other, the pinching pressure of the holding piece of the clip is attenuated with the separation, and the clip-based holding can be released through a simple operation.
  • Patent Literature 1 in this binder, three separate clips are arranged in the longitudinal direction of the long cover member.
  • a spread-shaped cover is provided for the purpose of paper protection and appearance improvement. In this configuration, a bundle of a plurality of sheets of paper is held and bound by the three clips and over the cover in a state where the bundle of a plurality of sheets of paper is sandwiched between the covers.
  • the sheet bundle is grasped with one hand from above the cover, the cover member is grasped with the other hand, and pulling is performed in a direction of separation.
  • the cover is formed of a synthetic resin or the like and the coefficient of friction of the surface thereof is low at this time, the pressing claw of the clip slides on the surface of the cover and the clip is separated from the cover and the sheet bundle without the clip and the cover member being relatively separated from each other. Accordingly, the clip is forcibly removed from the cover and the sheet bundle with the force of holding by the holding piece unattenuated. Then, the sheet bundle may collapse.
  • the clip removed from the cover and the sheet bundle remains stored in the cover member, and thus the clip portion that is stored needs to be pulled out once to the front side during sheet bundle re-binding, which has resulted in an increase in the complexity of paper addition or removal.
  • the present invention has been made in view of such a problem, and an object of the present invention is to provide a binder capable of smoothly adding or removing paper bound in a booklet shape regardless of the material of a cover.
  • the binder according to the present invention which is a binder forming a booklet by bundling end portions of a plurality of sheets of paper such that paper addition or removal is possible, includes: a spread-shaped cover configured for sandwiching the bundle of a plurality of sheets of paper; a long cover member having an opening portion along a spine portion of the cover; and a plurality of clips arranged so as to be configured for moving forward and backward in the opening portion of the cover member and having a pair of holding pieces and claw portions respectively extending inward from tips of the holding pieces, wherein through holes through which the claw portions of the plurality of clips are respectively inserted are formed in each of a front cover member and a back cover member of the cover.
  • the claw portions of the plurality of clips are inserted through the through holes formed in the cover and directly abut against the front surface of the paper on the uppermost surface and the back surface of the paper on the lowermost surface, respectively. Accordingly, when the bundle of a plurality of sheets of paper is grasped from above the front cover and the sheet bundle and the cover member are pulled so as to be separated from each other, the frictional force that acts on the point where the claw portion and the sheet bundle abut against each other causes the cover member and the plurality of clips to operate so as to be relatively separated from each other without the clip and the sheet bundle moving relative to each other.
  • the pinching pressure of the holding pieces of the plurality of clips is attenuated during one operation with the separation.
  • the plurality of clips are pulled out of the opening portion of the cover member and the holding force is attenuated, and thus paper can be easily re-inserted into the internal space of the clip. In this manner, the work of adding or removing paper bound in a booklet shape can be smoothly performed regardless of the material of the cover.
  • the number of the plurality of clips is two and the clips are arranged near a longitudinal middle of the cover member. According to this preferable configuration, the clips are arranged near the middle of the long cover member. Accordingly, in a case where a bundle of a plurality of sheets of paper and the cover member are inclined and pulled so as to be separated from each other, the clip positioned on one longitudinal side away from the tilting fulcrum is moved so as to be separated to a large extent from the cover member. The clip positioned on the other longitudinal side near the tilting fulcrum is also moved in the direction of separation by following the clip on one side and the holding force of both clips can be attenuated by one operation.
  • a dimension from the tip to a rear end of the holding piece of the clip and a dimension from the spine portion of the cover to a spine portion-side edge portion of the through hole are substantially equal to each other. According to this preferable configuration, when the cover member and the cover are moved in a direction of separation, the inner corner portion that is the boundary between the holding piece and the claw portion and the spine portion-side edge portion of the through hole abut against each other, the clip moves together with the cover, and the clip can be reliably pulled out of the opening portion of the cover member.
  • a decorative member externally fittable to the cover member is detachably arranged on the cover member. According to this preferable configuration, the booklet bound to the binder is easily identified by means of the decorative member externally fitted to the cover member.
  • a front-rear dimension of the through hole is smaller than a front-rear dimension of the claw portion. According to this preferable configuration, the claw portion inserted through the through hole is unlikely to escape from the through hole and excellent operability is achieved.
  • FIGS. 1 to 7 The binder according to an embodiment of the present invention will be described with reference to FIGS. 1 to 7 .
  • the upper right side of the plane of FIG. 1 and the right side of the paper of FIG. 4 will be referred to as the front side, and the description will be provided with reference to the up-down, left-right, front-rear directions when viewed from the front side.
  • a binder 1 is a filing tool for removably holding a biding object P inserted in an internal space S1 of the binder 1 and binding it in a booklet shape.
  • the binder 1 is long and extends in the up-down direction.
  • the binder 1 includes a cover member 2 having a substantially U-shaped cross section with its front surface (upper right in FIG. 1 ) open in the longitudinal direction, two clips 3 and 3 built in the cover member 2 in an engagement state and arranged apart from each other in the longitudinal direction, and a spread-shaped cover 4 covering the biding object P.
  • the biding object P that can be bound by the binder 1 is a paper leaf such as a letter and a memo, another sheet, a booklet, a document, or the like.
  • the biding object P is a bundle of A4 copy paper.
  • the cover 4 is configured as a deformable sheet made of, for example, polypropylene, polyethylene terephthalate, another elastic resin, paper, or the like.
  • Fold portions 43 and 43 parallel to each other are formed so as to extend in the up-down direction in the substantially center of the unfolded cover 4 in the left-right direction.
  • a spine portion 40 having a lateral width is formed between the fold portions 43 and 43.
  • a front cover member 4A and a back cover member 4B are formed on the left and right sides of the spine portion 40.
  • Through holes 41 and 42 having the same rectangular shape are formed on each of the front cover member 4A and the back cover member 4B of the cover 4.
  • the through holes 41 and 42 are formed near the center of the cover member 4 in the up-down direction. Further, the through holes 41 and 42 of the front cover member 4A and the through holes 41 and 42 of the back cover member 4B are formed close to the spine portion 40 in the left-right direction. Further, the through holes 41 and 41 and the through holes 42 and 42 is respectively formed symmetrically with respect to the spine portion 40. When the fold portions 43 and 43 are folded in the same direction, the through holes 41 and 41 and the through holes 42 and 42 are opposed to each other (see FIG. 4 ).
  • fold portions 44 and 44 are formed in the up-down direction of the cover 4 so as to extend along spine portion-side edge portions 41a, 41a, 42a, 42a on the side of the spine portion 40 of the through holes 41 and 41 and the through holes 42 and 42, respectively. Accordingly, the cover 4 can be easily folded with the opening operation of the front cover member 4A.
  • the opening width of the through holes 41 and 42 in the front-rear direction from the spine portion-side edge portions 41a, 41a, 42a, 42a to end portion side edge portions 41b, 41b, 42b, 42b is formed so as to be smaller than the front-rear dimension of claw portions 3A, 3A described later. Accordingly, the claw portions 3A, 3A inserting through the through holes 41 and 42 are not likely to come off from the through holes 41 and 42 and excellent operability is achieved.
  • the clip 3 is a fastener formed so as to be elastically deformable, is made mainly of metal, hard synthetic resin, or the like, is formed into a substantially U shape in cross section, and is composed of a base portion 33, holding pieces 31 and 32, and the claw portions 3A and 3A.
  • the base portion 33 having a base portion width X1 is formed by folding from the vicinity of the center of the base portion 33, and the holding pieces 31 and 32 are formed to be continuous and spread out from the opposite ends of the base portion 33.
  • the pair of claw portions 3A and 3A extending inward toward the base portion 33 is formed so as to face each other.
  • the cover member 2 is formed of a metal, a hard synthetic resin, or the like so as to be less deformable than the clip 3 and a pair of pressing pieces 21 and 22 are formed on the tip side thereof with a substantially U-shaped cross section and across a base portion 23.
  • the outer surface side of the base portion 23 functions as a back cover and a seal or the like is stickable.
  • the insertion width Y1 that is formed between the tips of the pair of pressing pieces 21 and 22 is smaller than the width X1 of the base portion 33 of the clip 3.
  • the insertion width Y1 in the natural state is narrower than the width Y2 of the base portion 23 of a pressing cover 5.
  • engagement protrusions 21a and 22a are formed so as to protrude on the inside surfaces of the pressing pieces 21 and 22 of the cover member 2 and engagement recesses 3B and 3B (see FIGS. 1 and 2 ), which are slits, are formed in the holding pieces 31 and 32 of the clip 3.
  • the engagement protrusions 21a and 22a of the pressing pieces 21 and 22 and the engagement recesses 3B and 3B of the holding pieces 31 and 32 are fitted loosely, and the cover member 2 and the clips 3 and 3 are slidable and retained.
  • the cover member 2 is attached to the clip 3 such that the inside surfaces of the pressing pieces 21 and 22 are slidable and relatively movable in the insertion (proximity) and removal (separation) directions of the biding object P along the outer surfaces of the holding pieces 31 and 32 of the clip 3.
  • the biding object P as a bundle of a plurality of stacked sheets of paper is grasped and inserted into the internal space S1 formed by the front cover member 4A and the back cover member 4B facing each other in the cover 4. Specifically, a binding end portion P3 of the biding object P is inserted until it abuts against the spine portion 40 of the cover 4.
  • the spine portion 40 of the cover 4 abuts against the base portion 33 of the clip 3 when the biding object P is further pushed in with the binding end portion P3 of the biding object P abutting against the spine portion 40 of the cover 4.
  • the clip 3 is pushed in toward the base portion 23 side of the cover member 2 by the spine portion 40 of the cover 4.
  • the holding pieces 31 and 32 of the clip 3 are formed so as to be wider than the insertion width Y1 of the cover member 2. Accordingly, the holding pieces 31 and 32 of the clip 3 are gradually stored into the cover member 2 while being elastically deformed by being compressed from the up-down direction by the pressing pieces 21 and 22 of the cover member 2.
  • the claw portions 3A and 3A are compressed from the up-down direction by the pressing pieces 21 and 22, and thus an increase in elastic force occurs as the clip 3 is gradually stored into the cover member 2 and the biding object P is strongly held.
  • the clip 3 can be inserted until the base portion 33 abuts against the base portion 23 of the cover member 2.
  • the state where the base portion 33 of the clip 3 abuts against the base portion 23 of the cover member 2 is a state where the clip 3 is completely stored.
  • the force of holding by the pair of claw portions 3A and 3A is maximum in this state where the binding of the biding object P by means of the binder 1 is completed. It should be noted that an aspect in which the biding object P is grasped and pushed in toward the cover member 2 side during binding has been described and yet the present invention is not limited thereto and similar binding can be performed by grasping from above the cover 4 that covers the biding object P.
  • the biding object P is grasped from above the cover 4 along with the vicinity of the longitudinal middle portion of the cover member 2 and a relative movement is performed in a direction of mutual separation.
  • the frictional force caused by the tips of the pair of claw portions 3A and the front surface P1 and the back surface P2 of the biding object P causes the clip 3 to act so as to stay on the cover 4 side.
