Holder

technical field

The present invention relates to a holding device for binding the ends of a plurality of sheets to form a booklet.

Background technique

Booklets such as notebooks and books are formed by binding the ends of multiple sheets of paper with glue or thread. In addition, in order to classify and summarize documents and the like as necessary, a user may bind a plurality of sheets of paper to form a booklet. In such a case, conventionally, a so-called ring file or the like is often used. For example, a ring folder has a cover folded in half and a ring-shaped fastener as a holding unit for holding a plurality of sheets of paper on the back of the cover. The hole is inserted through the ring-shaped fastener, and paper can be added or removed as needed.

In addition, the clamping tool disclosed in Patent Document 1 has a long cover member arranged along the back of the cover, and the cover member has clips as holding means. This clip is a conventionally known technology as shown in patent document 2. The clip of Patent Document 2 is formed by bending an elastic metal thin plate, and a pair of opposing clamping pieces are extended from the ends in the width direction of the base, and are formed in a side view that opens in the direction of the cover. word shape. The pair of clamping pieces is formed to gradually expand toward the opening direction, and pressing claws are respectively formed to face each other so as to be bent toward the base side and inward at the front end of the clamping piece. When binding papers, a bundle of multiple sheets is inserted between a pair of clamping pieces of the clip so that they are slid and pressed in a U-shaped pressing member in a side view. As a result, the pair of holding pieces are pressed inside the pressing member, and the paper bundle can be strongly pressed by the returning elastic force of the pair of pressing claws compressed between the holding pieces and the paper bundle. By using such a clip, it is possible to bind the document in a booklet shape without forming a through hole in the document.

In addition, when releasing the clamping of the clip, it is only necessary to hold the paper bundle and the pressing member and pull them in the separating direction. In the initial action stage when the paper bundle and the pressing cover are pulled in the separation direction, the pressing claws of the clip are respectively pressed against the front of the uppermost paper and the back of the lowermost paper that are directly in contact with each other. The front and back of the paper stack will not move relative to each other due to the frictional force acting on the paper stack. Therefore, by sliding the inner surface of the opening of the pressing member and the surface of the clamping piece of the clip, the pressing member and the clip move in a manner of being relatively separated, and the clamping force of the holding piece of the clip is attenuated along with the separation, which can be achieved by simple operation. Unclamp the clip.

Returning to Patent Document 1, in this clamping tool, three clips are arranged so as to be separated from each other in the longitudinal direction of the elongated cover member. In addition, in Patent Document 1, for the purpose of protecting the paper and improving the aesthetics, it is configured to have a double-leaf cover member, and a paper bundle of a plurality of sheets is sandwiched between the cover members. It is bound by 3 clips.

Contents of the invention

The problem to be solved by the invention

In the clip-type folder of Patent Document 1, when the clip is released, the paper bundle is held from above the cover member with one hand, and the cover member is held with the other hand and pulled in a separation direction. At this time, assuming that the cover member is formed of synthetic resin or the like and has a low coefficient of friction on the surface, the pressing claw of the clip slides on the surface of the cover member, and the clip and the cover member are not relatively separated from each other. The cover unit is separated from the paper stack. Therefore, in the state that the clip is forcibly removed from the cover member and the paper bundle without attenuation of the clamping force of the holding piece, the paper bundle may lose shape. The clips are in the state of being stored in the cover member, so when the paper bundle is to be stapled again, it is necessary to pull out the clip part in the stored state to the front side, and the work of adding or removing paper is cumbersome.

The present invention has been made with such problems in mind, and an object of the present invention is to provide a holding tool capable of smoothly adding or removing paper bound into a booklet without being limited by the material of the cover member.

means to solve the problem

In order to solve the above-mentioned problems, the holding device of the present invention binds the ends of a plurality of sheets of paper in a manner that can add or remove paper to form a booklet, and is characterized in that the holding device has: a double-leaf cover member, It can hold a paper bundle of a plurality of sheets; an elongated cover member having an opening along the back of the cover member; In the opening of the opening, the clip has a pair of clamping pieces and claws extending inward from the front ends of these clamping pieces, respectively. The front cover and the back cover of the cover member are respectively formed with a plurality of The claws of the clip are inserted through the through-holes respectively.

According to this feature, the claws of the plurality of clips are inserted through the through-holes formed on the cover member, and directly abut against the front of the uppermost paper and the back of the lowermost paper respectively. When a paper bundle of multiple sheets is pulled in a direction to separate the paper bundle from the cover member, the clip and the paper bundle do not move relative to each other due to the frictional force acting at the position where the claw portion and the paper bundle abut against each other, and the cover member and the multi-sheet bundle are not moved relative to each other. Each clip acts in a relatively separated manner, and with the separation, the clamping force of the clamping pieces of the multiple clips decays during one action. Furthermore, since the plurality of clips are pulled out from the opening of the cover member and the clamping force is attenuated, the paper can be easily inserted into the internal space of the clip again. Thereby, the work of adding or removing paper bound in a booklet can be smoothly performed without being limited by the material of the cover member.

Two of the plurality of clips are arranged near the center in the longitudinal direction of the cover member.

According to this feature, the clip is arranged close to the center of the elongated cover member, so when the bundle of multiple sheets and the cover member are twisted in a direction to be obliquely separated, the clip located on the side farther from the tilt fulcrum in the longitudinal direction The clip moves in a direction far away from the cover member, and even the clip on the other side near the tilt fulcrum in the longitudinal direction will follow the clip on one side and move in the direction of separation, and the two clips can be separated by one action. Any one of the clamping force attenuation.

It is characterized in that the dimension from the front end to the rear end of the clamping piece of the clip is formed substantially the same as the dimension from the back side of the cover to the back side edge of the through hole.

According to this feature, when the cover member and the cover member are moved in the direction of separation, the inner corner portion as the boundary between the clamp piece and the claw portion abuts against the back side edge of the through hole, and the clip moves together with the cover member, and the clip can be moved. Pull it out from the opening of the cover member securely.

It is characterized in that a decorative member that can be fitted on the cover member is detachably arranged on the cover member.

According to this feature, the booklet bound to the holder becomes easy to recognize by the decorative member fitted on the outside of the cover member.

It is characterized in that the front-back direction of the said through-hole is formed smaller than the front-back dimension of the said claw part.

According to this feature, the claw portion inserted into the through hole is less likely to fall out of the through hole, and the operability is excellent.

Detailed ways

Hereinafter, the form for implementing the clamping tool of this invention is demonstrated based on an Example.

Example

The holding tool of the embodiment will be described with reference to FIGS. 1 to 7 . Hereinafter, the upper right side of the plane in FIG. 1 and the right side of the page in FIG. 4 are regarded as the front side, and the up, down, left, right, front and back directions when viewed from the front side are taken as a reference for description.

As shown in Fig. 1 and Fig. 2, the clamping device 1 of the embodiment of the present invention is used to clamp and bind the clamped object P inserted into the internal space S1 of the clamping device 1 in a detachable manner. Booklet-like filing tool. The clamping device 1 has: a cover part 2, which is a strip extending up and down, and the front (upper right side of Fig. 1) of the cover part 2 is open in the length direction, and is roughly U-shaped in cross-section; two clips 3, 3 , the two clips 3, 3 are built into the cover member 2 in an engaged state, and are arranged separately in the longitudinal direction;

The clamped object P that can be bound by the clamping tool 1 is paper such as letters and memos, other sheets, booklets, documents, etc., and is a bundle of A4 size copy paper in this embodiment.

As shown in FIG. 3 , the cover member 4 is made of, for example, a deformable sheet made of polypropylene, polyethylene terephthalate, other elastic resins, paper, or the like. At approximately the center of the unfolded cover member 4 in the left-right direction, creases 43, 43 are formed to extend up and down in parallel, respectively. The back 40 has a left and right width, and a front cover 4A and a back cover 4B are formed on the left and right of the back 40 .

The same rectangular through-holes 41 and 42 are respectively formed in the front cover 4A and the back cover 4B of the cover member 4 . The through-holes 41 and 42 are formed at positions close to the center in the vertical direction of the cover member 4 . In addition, the through-holes 41 and 42 of the front cover 4A and the through-holes 41 and 42 of the back cover 4B are formed close to the back 40 in the left-right direction. Furthermore, the through-holes 41, 41 and the through-holes 42, 42 are symmetrically formed with the back portion 40 as the center. It becomes opposite (refer to FIG. 4). Furthermore, in the vertical direction of the cover member 4, creases 44, 44 are formed along the back side edge portions 41a, 41a, 42a, 42a of the through holes 41, 41 and the back side 40 side of the through holes 42, 42, respectively. This makes it easy to bend along with the opening operation of the front cover 4A.

In addition, the opening width in the front-rear direction from the back side edge portions 41a, 41a, 42a, 42a to the end portion side edge portions 41b, 41b, 42b, 42b of the through holes 41, 42 is formed to be wider than the claw portion 3A, which will be described later. 3A has small front and rear dimensions. Accordingly, the claw portions 3A, 3A inserted through the through holes 41 , 42 are less likely to come off from the through holes 41 , 42 , and the operability is excellent.

Next, the structures of the clip 3 and the cover member 2 will be described using FIG. 7 . The clip 3 is an elastically deformable fastening tool mainly made of metal or hard synthetic resin, and is formed in a substantially U-shaped cross-sectional view by a base 33 , holding pieces 31 , 32 , and claws 3A, 3A. Specifically, a base 33 having a base width X1 is formed by bending from the central side of the base 33, and the clamping pieces 31, 32 are continuously and spread out from both ends of the base 33. A pair of claw portions 3A, 3A extending inward toward the base portion 33 are formed facing the front ends of the pieces 31 , 32 .

The cover member 2 is made of metal or hard synthetic resin and is less deformable than the clip 3 , and a pair of pressing pieces 21 and 22 are formed on the front end side of the cover member 2 to sandwich a base 23 to form a substantially U-shaped cross-sectional view. The outer surface side of the base 23 functions as a spine, and stickers and the like can be attached. In addition, the insertion width Y1 formed between the front ends of the pair of pressing pieces 21 , 22 is formed in a shape narrower than the width X1 of the base portion 33 of the clip 3 . In addition, the insertion width Y1 in the natural state is narrower than the width Y2 of the base portion 23 of the pressing cover 5 .

In addition, engaging protrusions 21a, 22a are protrudingly formed on the inside surfaces of the pressing pieces 21, 22 of the cover member 2, and engaging concave portions 3B, 3B are formed as slits on the holding pieces 31, 32 of the clip 3. (Refer to Figure 1, Figure 2). The engaging protrusions 21a, 22a of the pressing pieces 21, 22 and the engaging recesses 3B, 3B of the clamping pieces 31, 32 are concave-convexly fitted in a gap fit shape, so that the cover member 2 and the clips 3, 3 can slide freely and prevent take off. The cover member 2 is attached to the clip 3 in such a manner that the inner surfaces of the pressing pieces 21, 22 can be moved along the outer surfaces of the clamping pieces 31, 32 of the clip 3 in the direction of insertion (approaching direction) and removal of the object P to be clamped. The direction (separation direction) slides relatively freely.

Next, a mode in which the clamping tool 1 clamps the object P to be clamped will be described with reference to (a) to (c) of FIG. 4 . First, as shown in (a) of FIG. 4 , the held object P obtained by stacking a plurality of sheets of paper is held and inserted into the front cover 4A and the back cover 4B formed by the cover member 4 facing each other. Inside the inner space S1. Specifically, the binding end portion P3 of the object to be clamped P is inserted until it abuts against the back portion 40 of the cover member 4 . During this insertion, the front ends of the pair of claws 3A, 3A of the clip 3 inserted into the through-holes 41, 42 of the cover member 4 and protruding into the internal space S1 are in contact with the front side of the object P to be clamped, respectively. The surface P1 and the rear surface P2 are in contact with each other.

Next, as shown in FIG. 4( b ), when the clamped object P is further pushed in from the state where the bound end portion P3 of the clamped object P is in contact with the back 40 of the cover member 4 , the back 40 of the cover member 4 The clip 3 is pushed in by the back portion 40 of the cover member 4 toward the base portion 23 of the cover member 2 when it abuts against the base portion 33 of the clip 3 and is further pushed in.

Since the holding pieces 31, 32 of the clip 3 are formed wider than the insertion width Y1 of the cover member 2, the holding pieces 31, 32 of the clip 3 are compressed from the vertical direction by the pressing pieces 21, 22 of the cover member 2 to generate elasticity. It is gradually accommodated inside the cover member 2 while being deformed. Since the claws 3A, 3A are compressed from the vertical direction by the pressing pieces 21, 22, as the clip 3 is gradually accommodated inside the cover member 2, the elastic force of the claws 3A, 3A gradually increases, and the object P to be clamped is strongly clamped. .

As shown in (c) of FIG. 4 , the clip 3 can be inserted until the base 33 abuts against the base 23 of the cover member 2, and the state where the base 33 of the clip 3 abuts against the base 23 of the cover member 2 is a state in which the storage is completely completed. . This state is a state where the clamping force of the pair of claws 3A, 3A is at its maximum, and binding of the objects P to be clamped using the clamping tool 1 is completed in this state. In addition, although the method of holding the object P to be held and pushed toward the cover member 2 side at the time of stapling has been described, it is not limited to this, and if it is held from the cover member 4 covering the object P, the same can be done. to bind together.

Next, a mode of releasing the clamped state between the clamping tool 1 and the clamped object P will be described using (a) to (c) of FIG. 5 .

When detaching the clamped object P from the clamping tool 1, the vicinity of the center portion in the longitudinal direction of the cover member 2 is grasped, and the clamped object P is grasped from the cover member 4, and are relatively moved in directions to separate from each other. When moving relative to each other in the direction of separation, the clip 3 tends to remain on the cover member 4 due to the frictional force between the front end of the pair of claws 3A and the front side surface P1 and the back side surface P2 of the object to be clamped P. side, so that the base 23 of the cover part 2 is separated from the base 33 of the clip 3 , and the clip 3 protrudes from the cover part 2 . As a result, the compressive force received by the claws 3A, 3A from the vertical direction of the pressing pieces 21, 22 is weakened, and as the clip 3 is gradually pulled out to the outside of the cover member 2, the elastic force of the claws 3A, 3A is attenuated, and the clip 3 is attenuated. The clamping force of the holding object P is weakened, and it will be in the state shown in FIG.5(a).

When the object P is grasped from the cover member 4 and the cover member 2 and the object P are further moved relative to each other in the direction of separation, the cover member 4 moves toward the front side of the object P, so that the claw portion is formed The inner corner portion 34 of the boundary between 3A and 3A comes into contact with the back side edge portions 41 a and 42 a of the through holes 41 and 42 , resulting in a state shown in FIG. 5( b ).

When the cover member 2 and the cover member 4 are further moved relative to each other in the direction of separation from the state shown in FIG. Therefore, the cover part 4 plays the role of pulling the clip 3 out of the cover part 2 . Since the clamping force of the claw portions 3A, 3A becomes weaker as the inner corner portion 34 pulls the cover member 4 out, the cover member 4 pulls the clip 3 out of the cover member 2 when relatively moving in the direction of separation. The amount gradually increases. Thereby, the clip 3 shown in FIG. 5( c ) is completely pulled out from the cover member 2 , and the storage release state is achieved. At this time, the clamping force of the claw portions 3A, 3A is the smallest.

When detaching the clamped object P from the clamping tool 1, for example, the vicinity of the upper end portion in the longitudinal direction of the cover member 2 and the vicinity of the lower end portion of the cover member 4 are accidentally moved relative to each other in directions that are obliquely separated from each other. In the case of , the clip 3 (on the upper side of the paper) located on the side away from the tilt fulcrum in the longitudinal direction moves to the direction in which the cover member 2 and the clip 3 are largely separated due to friction with the clamped object P, and the grip of the claw portion 3B The holding force is weakened, and the clip 3 protrudes. The clip 3 (on the upper side of the drawing) and the cover member 2 located on the other side near the tilting fulcrum in the longitudinal direction are also formed because the cover member 2 extends in the vertical direction, and the clips 3, 3 are closer to the end of the cover member 2. Since the center side is arranged, the clip 3 on the other side will also follow the clip 3 on one side and move in the direction of separation, and the clamping force of the claw part 3B will be weakened, and the clips 3 and 3 will protrude as shown in FIG. 6 . Thereby, the object P to be clamped can be replaced smoothly.

The cover member shown in FIG. 7 shows a modified example in which the positions of the above-mentioned pair of through holes 41 and 42 are changed. In the pair of through holes 410 and 420 of the cover member 400 shown in the modified example, the distance from the outer surface of the back portion 40 of the cover member to the back side edge of the through hole is changed. Specifically, the distance b from the outer surface of the back portion 40 of the cover member 400 to the back side edge portions 410a, 420a of the through holes 410, 420 in the modified example is formed to be equal to the distance b from the inner surface of the base portion 33 of the clip 3 to the claw portion 3A. The distance a of the inner corner portion 34 turned back toward the inner side surface is substantially the same.

When attaching the cover member 400 to the clip 3, the clip 3 is slid forward from the cover member 2 to be in the storage release state, and the claw portion 3A on one side of the clip 3 is inserted into the one side formed on the cover member 400. In the through hole 410 , the inner corner 34 of the claw 3A and the back side edge 410 a of the through hole 410 are brought into contact with each other, whereby the one claw 3A of the clip 3 and the one through hole 410 are engaged. Since the cover member 400 is formed in a deformable sheet shape, when engaging the other claw portion 3A with the other through hole 410, as shown in FIG. The other side of the clip 3 is bent to insert the other claw 3A of the clip 3 into the other through hole 410 formed on the cover member 400, so that the inner corner 34 of the claw 3A is aligned with the back side edge of the through hole 410. 410a are respectively abutted.

(a) of FIG. 9 shows Modification 1 of the above-mentioned cover member. The cover member 20 of Modification 1 is formed with protruding portions 2b extending up and down at the rear end and both sides of the outer surface 2a of the cover member 20. 2c, 2c. The decorative member 6 that can be fitted on the cover member 20 is detachably arranged on the cover member 20 . The decorative member 6 has a substantially U-shaped cross-sectional view, extends up and down, and is formed slightly larger than the cover member 20 . The upper and lower dimensions of the decorative member 6 are substantially the same as those of the cover member 20 . In addition, recesses 6b, 6c, and 6c extending up and down are formed on the rear end and both sides of the inner surface 6a of the decorative member 6, and by sliding the lower end of the decorative member 6 against the upper end of the cover member 20, The protruding portions 2b, 2c, and 2c are engaged with the recessed portions 6b, 6c, and 6c, and the decorative member 6 is externally fitted on the entire outer surface 2a of the cover member 20 .

The decorative member 6 is formed of synthetic resin or the like, and by fitting the decorative member 6 to the cover member 20, the strength of the cover member 20 is improved, and by further changing the color tone and texture of the decorative member 6, it becomes easy to identify the binding device 1 The clamped object P. In addition, the appearance of the holding tool 1 is also improved by using a transmissive material for the decorative member 6 . In addition, the decorative member 6 is formed with a display portion 6A provided by coating the outer surface or pasting stickers, etc., and by writing the title, content, etc. of the object P to be held on the display portion 6A, it is possible to recognize the object bound to the holding device. Contents of the clamped object P. In addition, since the display portion 6A of the decorative member 6 has a flat display surface outside the outer surface of the base of the cover member, it is easy to write characters on the display portion 6A for easy recognition.

(b) of FIG. 9 shows Modification 2 of the above-mentioned cover member. The cover member 12 of Modification 2 is formed with protrusions 12b extending up and down on the rear end sides of both sides of the outer peripheral surface 12a of the cover member 12. 12b. The cover member 12 is detachably provided with a decorative member 60 that can be externally fitted on the rear end portion of the outer peripheral surface 12 a. The decorative member 60 has a substantially U-shaped cross-sectional view, extends up and down, and has both sides shorter than those of the decorative member 6 of Modification 1. As shown in FIG. The upper and lower dimensions of the decorative member 60 are substantially the same as those of the cover member 12 . In addition, recessed portions 60b, 60b extending up and down are formed on the rear end portion and both sides of the inner surface 6a of the decorative member 60, and the lower end portion of the decorative member 60 is brought into contact with the upper end portion of the cover member 12 to slide, and the protruding portion 12b and 12b are engaged with the recessed parts 60b and 60b, and the decorative member 60 is externally fitted in the whole outer surface 2a of the cover member 20. As shown in FIG. In addition, since the both sides of the decorative member 60 are formed shorter than the both sides of the decorative member 6, the weight is light, the processing is easy, and the attachment to the cover member is easy.

In this way, in the holding device 1 that binds the ends of a plurality of sheets of paper to form a booklet in a manner that can add or remove paper, the holding device 1 has a plurality of clips 3, and the front cover 4A and the back cover of the cover member 4 4B are respectively formed with through-holes 41, 42 through which the claws 3A of the plurality of clips 3 are respectively inserted. They directly abut against the front side P1 of the uppermost paper and the back side P2 of the lowermost paper respectively. Therefore, when holding a bundle of multiple sheets from the cover and pulling it in a direction to separate the bundle from the cover member 2, Because the clip 3 and the object to be held P do not move relative to each other due to the frictional force acting on the part where the claw portion 3A and the object to be held P abut against each other, the cover member 2 and the plurality of clips 3 act in a relatively separated manner, and the separation is accompanied by During one movement, the clamping force of the clamping pieces 31 and 32 of the plurality of clips 3 is attenuated, so that the relative movement of the cover member 2 and the clips 3 is facilitated. In addition, since the plurality of clips 3 are pulled out from the opening of the cover member 2 and the clamping force is attenuated, the paper can be easily inserted into the internal space of the clip 3 again. In this way, regardless of the time of detachment or insertion, the work of adding or removing paper bound in a booklet can be smoothly performed without being restricted by the material of the cover member 4 . In addition, in the case of new use, when the back side edges 41a, 42a of the cover member 4 are brought into contact with the inner corners 34, 34 of the clip 3 and the cover member 2 and the cover member 4 are relatively moved in a direction to separate, Since the cover member 4 functions to pull the clip 3 out of the cover member 2, it can easily be brought into the storage release state.

In addition, since two of the plurality of clips 3 are arranged near the center of the cover member 2 in the longitudinal direction, the clip 3 is arranged near the center of the elongated cover member 2. 2 In the case of twisting in the direction of oblique separation, the clip 3 located on the side away from the tilt fulcrum in the longitudinal direction moves in a direction far away from the cover member 2 by a large amount, even if the clip 3 located on the other side close to the tilt fulcrum in the longitudinal direction 3. It also follows the clip 3 on one side and moves in the direction of separation, so that the clamping force of any one of the two clips 3 can be attenuated by one action.

In addition, the clip 3 is formed with an inner corner 34 folded back from the front ends of the clamping pieces 31 and 32 to the inner space, and the size from the rear end of the clip 3 to the inner corner 34 is the same as that from the back 40 of the cover member 4 to the through hole 41. The dimensions of the back side edge portions 41a, 42a of , 42 are formed to be substantially the same, therefore, when the cover member 2 is moved in the direction of separation relative to the clamped object P, the inner corner portion 34 and the back side edges of the through holes 41, 42 The parts 41a and 42a abut against each other, the clip 3 moves together with the cover member 4, and the clip 3 can be pulled out from the opening of the cover member 2 reliably.

In addition, the cover member 2 is detachably provided with the decorative member 6 that can be fitted on the cover member 2. Therefore, by attaching the decorative member 6 to the cover member 2, it becomes easy to recognize the objects bound to the clamping tool 1. Holder P.

Also, since the front-rear opening width of the through holes 41 , 42 is formed smaller than the front-back dimension of the claw portion 3A, the claw portion 3A inserted into the through holes 41 , 42 is less likely to fall out of the through holes 41 , 42 .
