Description

  The present invention relates to a binding tool that can hold a paper sheet in a spread state, and a file including the binding tool.

A binding tool for binding paper sheets such as documents or a file (sometimes referred to as a binder) provided with such a binding tool has left and right or top and bottom as viewed from the user. There is something that can be distributed and used in the spread state. As an example of such a file, a file comprising a cover body having a pair of front cover part, back cover part and spine cover part, and a binding tool having a base attached to the cover body and a binding main body part. (For example, refer to Patent Document 1). The file described in the same document includes a base body fixed to a spine portion of a cover body as a base in a binding tool, and a pair of plate members pivoted by hinges at both side end portions of the base body. In addition, as a binding main body portion, a binding rod having curved shapes respectively provided on a front cover side and a back cover side plate material to be inserted into a binding hole formed in a paper sheet (of the same document) In the example, two plates are provided for each plate. Note that the binding rods that face each other with the base body interposed therebetween are arranged so as to overlap and engage with each other in a state in which the paper sheets are inserted into the binding holes. As described above, each binding rod has a curved shape so as to form a partial arc as a whole.

  However, when the configuration of the binding tool is as described above, a bent portion that is a boundary between the proximal end portion of the binding rod and the curved portion ahead of the binding rod is exposed. There is a risk that the binding holes of the paper will be caught and the paper sheets will be torn from there. Such a problem is particularly noticeable when browsing, writing, or page turning in a state where the paper sheet is wide open.

  Therefore, in view of the above problems, the present invention makes it easy to attach a binding body such as a binding rod to a base, and a binding tool that can suitably prevent paper sheets from being torn from a binding hole, In addition, a file including the binding tool is provided.

  That is, the binding tool of the present invention is a binding formed on a paper sheet that is attached to a cover body that includes a front cover portion and a back cover portion that form a front / back pair, and a back cover portion interposed between the cover portions. A binding tool that can hold the paper sheets in a spread state in which a part of the paper sheet is sorted into a front cover part and a back cover part by inserting a part into the hole, and the front cover part of the front cover part or the back cover part A pair of bases attached to the side and the back cover part of the back cover part or the back cover part respectively hold the paper sheets by engaging with each other in a state of extending facing each other and being inserted into the binding hole. A binding body that is attached to each base in pairs, and a cover body that is attached to the base or cover body so as to cover the base end portion of each binding body, and each binding body, A pair at the base end attached to the base An upright portion that rises linearly with respect to the opposing surfaces of the bases, and a binding body portion that is bent from the upright portion and extends in a direction different from the upright portion and is inserted into the binding hole of the paper sheet The cover body is formed so as to cover a region extending from an upright portion of each binding body to a bent portion that is a boundary between the upright portion and the binding main body.

  In the binding tool having such a configuration, the base end portion of the binding body inserted into the binding hole of the paper sheet has an upright portion that rises linearly with respect to the opposing surface of the base. Good workability of attaching to the base can be obtained, and positioning of the binding body with respect to the base can be suitably performed. In addition, since the bent portion at the boundary between the standing portion and the binding main body portion is hidden by the cover body together with the standing portion, the binding hole of the paper sheet is prevented from being directly caught by the bent portion and broken. Can do. Therefore, it is possible to open, browse, write, and turn pages by eliminating the possibility of damage to the paper sheets that are bound with the binding tool of the present invention. In the present invention, the specific shape and configuration of the base are not particularly limited. In addition, the binding body is inserted into a binding hole such as a pipe type, ring binder type (regardless of ring shape), MP (multi-prong) binder type, AZ file format, and Excon file format. Any one of the types that hold the sheet is included, and it is only necessary to include an appropriate number of binding bodies according to the number of binding holes formed in the paper sheet. Furthermore, the standing angle with respect to the opposing surface in the base of the standing portion can be appropriately set.

  In order to achieve smooth page turning without hooking a binding hole to any part of the binding body when turning the page with the paper spread, the binding main body part is directed to the opposite binding main body part. A curved shape is preferable.

  In order to make the attaching operation and positioning of the binding body to the base extremely efficient, it is preferable that the standing portion of the binding body is substantially upright with respect to the opposing surface of the base.

  Furthermore, in order to improve the stability of the binding body with respect to the base, it is preferable to fix the base end portion in contact with the base among the standing portions in a state where the base end portion penetrates the base.

  In particular, if the binding body and the base are made of metal and the cover body is made of resin, the durability of the binding tool is improved, and the contact of the paper sheets with the cover body is made softer to prevent damage more appropriately. Can do. In this case, an appropriate mode of caulking, welding, screwing, or the like can be selected as the mode of mounting the binding body to the base.

  In addition, as a suitable example for realizing the downsizing of the binding tool by providing the cover body with functions other than the protection function of the proximal end portion and the bent portion of the binding body, the cover body includes a pair of binding bodies as a pair. The thing which provided the lock mechanism which maintains an engagement state or cancels | releases the said engagement state can be mentioned.

  The file according to the present invention is provided with the above-described binding tool. More specifically, a front cover portion comprising a front cover portion and a back cover portion that form a front / back pair, and a back cover portion interposed between the front cover portions, and a front cover portion of the front cover portion or the back cover portion. The base is attached to the side and the back cover part side of the back cover part or the back cover part of the spine cover part, and the binding body part is inserted into the binding hole formed in the paper sheet to cover the paper sheet It is characterized in that it is provided with a binding tool that can be held in a spread state that is distributed between the side and the back cover portion side, and by providing such a binding tool, the above-described operational effects can be obtained. . In the present invention, the concept of “file” includes what is generally called a “binder” having a binding tool.

  The binding tool of the present invention has an upright portion that rises linearly with respect to the opposing surface of the base at the base end portion of the binding body that is inserted into the binding hole of the paper sheet, and has different directions from the upright portion. It is assumed that the binding main body portion extended to can be inserted into the binding holes of the paper sheets. Therefore, since the standing portion is first formed on the binding body, it is possible to obtain good workability of the attachment process to the base, and it is possible to favorably position the binding body with respect to the base. Next, since the standing part and the bent part at the boundary between the standing part and the binding main body part can be concealed by the cover body, the binding hole of the paper sheet is directly caught by the bent part. It can be eliminated. Therefore, when a paper sheet is bound and held in a file having such a binding tool, the possibility of damage from the binding hole of the paper sheet is reduced as much as possible, and there is no possibility of causing such damage. Browsing, writing, and page turning are possible with the leaves open.

This lock claw Ra is formed as a pair in the vicinity of the tip end portion and the longitudinal center portion of the slide shaft Rb provided in the block portion 522b and the plate-like portion 522a so as to be slidable in the vertical direction. is there. Further, the lower end portion of the slide shaft Rb is provided so as to protrude downward from the lower end of the plate-like portion 522a, and a block-like operating body Rc is integrally provided at the lower end. Although not shown, an urging means for elastically urging the lock claw Ra, the slide shaft Rb, and the operating body Rc integrally to the lower end side of the spine portion K3 is provided at an appropriate position of the slide shaft Rb. In the present embodiment, as the biasing means, a resin spring is used which is formed in a continuous bowl shape with the upper end portion of the slide shaft Rb being partially thin. The upper end portion of the resin spring is used as the upper end portion of the block portion 522b. The lock claw Ra, the slide shaft Rb, and the operating body Rc are integrally elastically urged downward as a result of being in contact with each other from below. The lock claw Ra is formed with two hooks Ra1 and Ra2 stepwise from the base end side to the tip end side in the extending direction. Each of these hooks Ra1 and Ra2 has a claw shape protruding toward the lower end side of the spine portion K3. On the other hand, in the block portion 512b on the first cover member 51 side, a lock hole Rd for engaging the lock claw Ra so as to be insertable / removable is opened toward the opposing block portion 522b side. That is, the lock mechanism R provided in the cover body 5 has a function of switching the following three states. First, when the operating body Rc and the slide shaft Rb are pulled out to the lower end side of the back cover portion K3 to the maximum, as shown in FIG. 1, the block portions 512b and 522b are brought into substantially contact with each other, and the lock pawl Ra In a state in which the hook Ra1 on the base end side is engaged with the lock hole Rd, the binding shaft 3 is almost completely inserted into the binding tube 4 to be in a completely closed state. In this state, the front cover portion K1 and the back cover portion K2 face each other and the file F is closed and stored, or when the number of sheets P to be bound is small, the front cover portion K1 and the back cover portion K2 Suitable for use with two-page spread. Next, when the operating body Rc is once pushed upward to release the engagement between the hook Ra1 and the lock hole Rd and the hook Ra2 and the lock hole Rd on the distal end side are engaged, FIG. 2 and FIG. As shown, the proximal end side of the binding body portion 3b in the binding shaft 3 is pulled out from the binding tube 4 and is in a half-open state in which the distal end portion is inserted. At this time, the hinge Kh3 of the spine portion K3 is a shallow valley fold when viewed from the outer surface side of the cover body K. In this state, the front cover portion K1 and the back cover portion K2 face each other and the file F is closed and stored, or when the number of sheets P to be bound is large, the front cover portion K1 and the back cover portion K2 Suitable for use with two-page spread. Finally, in a state where the operating body Rc is further pushed upward and the engagement between the hook Ra2 and the lock hole Rd is released, the binding shaft 3 is fully extracted from the binding tube 4 as shown in FIG. It becomes a state. At this time, the hinge Kh3 of the back cover portion K3 is deeply folded when viewed from the outer surface side of the cover body K. This state is suitable when the paper sheet P is added or removed. As described above, the lock mechanism R can selectively form the binding tool 1 in any one of the three stages. The file F is used to change the sheet P according to the number of sheets. It is intended to be used properly in the spread state.

  As described in detail above, in the file F of the present embodiment, the binding tool 1 includes the base 2, the binding shaft 3 and the binding tube 4 as the binding body attached to the base 2, and the binding shaft 3 and the binding tube. 4 is provided with a cover body 5 covering the base end portion. In particular, since the proximal end portions of the binding shaft 3 and the binding tube 4 are raised portions 3a and 4a that rise substantially perpendicularly from the opposing surfaces 2a and 2a of the base 2, the binding shaft 3 and the binding tube 4 are fixed to the base 2 by a caulking method or the like. The positioning of the binding shaft 3 and the binding tube 4 and the ease of work are improved when penetrating and attaching them. Although the upright portions 3a and 4a are formed in the binding shaft 3 and the binding tube 4, the region from the upright portions 3a and 4a to the bent portions 3c and 4c is covered by the cover portion of the cover body 5. Since it is completely covered by 511 and 521, the binding hole Ph of the bound paper sheet P does not contact the bent portions 3c and 4c, so that it is preferable to break the paper sheet P from the binding hole Ph. Can be prevented.

  Further, in the binding shaft 3 and the binding tube 4, the binding main body portion having a curved shape in which the region on the tip side from the bent portions 3 c and 4 c is inserted directly or indirectly into the binding hole Ph of the paper sheet P. 3b and 4b make it possible to perform page turning particularly smoothly when the paper sheet P is spread apart, and this also prevents the paper sheet P from being damaged from the binding hole Ph. it can.

  Further, the binding shaft 3 and the binding tube are formed on the cover body 5 so that the front cover portion K1 and the back cover portion K2 of the file F are opened so that the sheet P can be viewed and written in a spread state. Since the lock mechanism R that maintains the engaged state 4 is incorporated, it is not necessary to provide a mechanism for ensuring the spread state in addition to the above-described configuration, and the binding tool 1 itself can be effectively downsized. Can be planned.

  The present invention is not limited to the embodiment described above. In particular, as a binding body, a binding shaft having a claw that extends from a pair of opposing bases and engages between tip portions, or a binding shaft that has protrusions or recesses that are pierced and engaged with each other at the tip portions, Appropriate modes such as a binding shaft that overlaps and engages with each other as in the above-described Patent Document 1 and a binding shaft and a binding tube that are linearly inserted and removed can be adopted. The number of bodies can be set to an appropriate number according to the number of binding holes of the paper sheets. Further, as long as the binding body itself can maintain the spread state of the paper sheet, it is not particularly necessary to provide a lock mechanism as in the present embodiment, and even if a lock mechanism is provided, it is not necessarily provided in the cover body. There is no need to incorporate it. In addition, the specific configuration such as the base and the cover body is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
