Abstract

Files in which multiple cover sheets are formed from a single resin sheet are files in which the sheet is provided with a thin resin section and adjacent cover sheets are respectively disposed with said thin resin section therebetween. When the cover sheets of such files are opened and closed, because an internal stress is exerted on the thin resin section, not only does that area deteriorate markedly compared to other areas but, if the file is formed so that the cover sheet is easy to open by turning in one direction, the load on the thin resin section when the cover sheet is turned in the reverse direction is increased. The file according to the present invention has multiple cover sheets formed from a first material and a hinge formed from a second material that has a higher elasticity than the first material, and one cover sheet is joined to the other cover sheet via the hinge. As a result, when the one cover sheet is turned relative to the other cover sheet to open or close the file, the internal stress generated by the turning is absorbed by the high elasticity of the hinge.

The present invention relates to a kind of file, the lid of this document folder is molded by synthetic resin.

Background technology

In the regular file with synthetic resin cap and spine presss from both sides, cap and spine pass through thin-walled resin portion integratedly Formed, and thin-walled resin portion serves as hinge, the following two kinds state realized by this hinge：Cap and the state of spine's level, and The state that cap bends with respect to spine, i.e. the open mode of file and closure state.

The uncensored and disclosed application of [patent document 1] Japan Patent the 2001-47782nd

Content of the invention

The file that wherein synthetic resin cap and spine form has thin-walled resin portion, this thin-walled resin portion quilt A side being arranged in single synthetic resin sheet material upwardly extends so that the thin-walled resin as border is crossed over by cap and spine Portion arranges.Specifically, in the outer surface being formed at file towards the recess of the inner surface depression of file, thus in each lid The side of long side upwardly extend, and the bottom of recess constitutes thin-walled resin portion.Therefore, this document folder is adapted to pass through so that covering Portion rotates to close file along the direction towards inner surface with respect to spine, but so closure file leads to thin-walled resin Internal stress in portion.

On the other hand, when cap rotates along the direction towards outer surface from the open mode of file with respect to spine, The end of the recess in the end of the recess on cap side and on spine side contacts with each other so that by cap and spine each other The power that detached side pulls up acts on thin-walled resin portion from the contact site as starting point.Therefore, move if repeating this Make, then cap and spine can and thin-walled resin portion from.

In invention described in patent document 1, the direction of the long side that recess covers along each is in the outer surface of file Middle extension, and the groove towards outer surface depressions is formed near cap or the inner surface of spine, thus the length covered along each The direction of side extends.Therefore, when by make cap with respect to spine along towards inner surface direction rotate and close file When occur internal stress dispersion and be not centered in thin-walled resin portion.However, this invention does not assume that cap with respect to spine Rotate along towards the direction of outer surface, and therefore do not prevented due to this action along by direction separated from one another to cap and spine The power pulling acts in thin-walled resin portion.

The present invention solves simultaneously has synthetic resin cap and the existing issue of the file of spine, when making cap relative When the problem being met with when spine is rotated in a first direction and the second direction contrary with first direction when cap edge rotate The problem being met with.

The file of the present invention includes：The multiple lids being made up of the first material；And it is higher than the first material by having The hinge bodies that second material of elasticity is made and is connected with multiple lids, wherein lid is connected to each other by hinge bodies.

In the file of the present invention, a transverse end at least portion of a transverse end of lid, hinge bodies and hinge bodies Link together with dividing, link together preferably along almost its total length.

Substitute and lid and hinge bodies are directly linked together, lid and hinge bodies can be connected to one by union body Rise.Specifically, file includes being made up the union body of elongated shape of the first material, and a transverse end of union body and hinge One transverse end of serobila is at least partially joined together, and the side of union body is connected to the end of the side of lid, Lid and hinge bodies are indirectly connected together.Preferably, a horizontal stroke of a transverse end of union body and hinge bodies Link together to end along almost its total length.

Union body has base plate and base plate almost vertically disposed vertical plate and extend from vertical plate and have and bottom The upper plate of the almost parallel shape of plate, and there is the section of approximate U shape.Base plate or contact with vertical plate horizontal stroke of upper plate Can be connected with hinge bodies to end and vertical plate, and the end of lid can be with base plate towards the side of upper plate and upper plate Any one of the side towards base plate or both connect.In other words, lid can connect thus being maintained in approximate U shape.

File can include the first lid, the second lid and the 3rd lid, and each lid is made by the first material.The One lid and the 3rd lid can be adjacent to each other by first axle body, and the second lid and the 3rd lid can pass through second Hinge bodies are adjacent to each other.Specifically, on long side direction two transverse end of the 3rd lid respectively with hinge bodies one One transverse end of individual transverse end and another hinge bodies connects, and hinge bodies with a transverse end being connected to the 3rd lid Relative another transverse end is linked together with the first lid, the second lid and union body.

In accordance with the invention it is possible to provide such file, the cap of this document folder is moulded by synthetic resin, and this article Part folder is easy to by one cap is rotated approximate 360 degree with respect to adjacent another cap open, and thus without leading to The notable deterioration in this region in the concentration of the internal stress at a part for cap and compared to other regions.

If hinge bodies and lid are linked together by union body, the intensity of lid connects with lid and union body Strengthen, enabling prevent hinge bodies to be bent up in the unexpected side different from the direction opened or close file together Bent.And, if lid and union body are molded by identical material, hinge bodies and union body can extrude simultaneously and with Rear cover body and union body can be linked together by welding etc., or in other words, hinge bodies and lid can discretely be extruded. Therefore, for especially for having the lid of larger area, compared with when lid and hinge bodies are extruded simultaneously, in the molding phase Between the possibility that deforms can reduce.

In the case of including the regular file folder of the spine with fixed width, even if when by constraint in file When the thickness that the amount of the content of such as document is limited is less than the width of spine, the thickness (spine's width) of file is also protected Hold constant.In the file of the present invention, by contrast, constitute the entirety of spine in the closure state lower hinge body of file If or part is so that be less than by hinge by the thickness that the amount of the content of the such as document of constraint in file is limited The width that body can be formed, then hinge bodies can be extruded to the width of the width close to content.Therefore, especially work as this document When double-layered quilt is contained in shelf etc., file is compact and prevents take up significantly bigger than the thickness of the document being constrained in file Width.

Specific embodiment

Embodiments of the invention to be described below with reference to the accompanying drawings.In this specification, the length of the hinge bodies shown in Fig. 1 Direction be referred to as above-below direction, and the direction orthogonal with above-below direction is referred to as left and right directions.

(first embodiment)

In the file 1 of the first embodiment shown in Fig. 1 and Fig. 2, the lid 2 be made up of different synthetic resin materials Link together along almost total length in the vertical direction at their corresponding transverse end with hinge bodies 3.File 1 By being molded as follows：Make to form the obtained solution of material of lid 2 and by dissolving formation hinge master 3 by dissolving The solution that obtained of material pass through adjacent passage, and subsequently while cooling curing solution and make lid 2 and hinge Body 3 links together.

According to this embodiment, the part constituting the lid of file 1 is only lid 2 and hinge bodies 4.Therefore, it is possible to carry File for following cheap light weights：Its number of components is few and weight is no better than and has by the integral part of lid of thinner wall section The weight of the synthetic resin file of the routine of portion and spine.This embodiment is therefore suitably applied to lid 2 and has small area File.

However, due to must especially work as lid when control the flowing of two kinds of solution with different qualities simultaneously When body 2 has larger area, mould lid 2 and hinge bodies 3, so the lid being difficult to control to the flowing of relatively large solution and moulding 2 are likely to deform.For avoiding this problem, lid 2 and hinge bodies 3 can independently mould, and may then pass through adhesive Etc. be applied to any one of lid 2 and hinge bodies 3 or both and so that lid 2 and hinge bodies 3 is linked together.

(second embodiment)

In order to discretely mould lid 2 and hinge bodies 3 and and then in the instance where such an adhesive is not utilized by lid 2 and hinge Body 3 links together, as shown in figure 3, lid 2 and hinge bodies 3 can by by with the material identical material mould constituting lid 2 System union body 4 and link together.More specifically, the almost whole surface of the elongated side of tabular union body 41 all connects To hinge bodies 3, as shown in Figure 4.That is, the union body 41 in order to will be made up of different synthetic resin materials and hinge bodies 3 exist Link together along the almost total length in above-below direction at their corresponding transverse end, union body 41 and hinge bodies 3 are led to Cross and be molded as follows：Make the solution being obtained by the material of dissolving formation union body 41 and hinge bodies 3 are formed by dissolving The solution that obtained of material pass through adjacent passage, and and then while cooling curing solution and make union body 41 and hinge Serobila 3 links together.Then, a part for the lid 2 discretely moulding with union body 41 and hinge bodies 3 overlaps union body It is connected on union body 41 on 41 and by the method for such as welding.If these main bodys are made up of identical material, pass through It is not especially difficult that lid 2 and union body 41 are linked together by welding.However, the method is not limited to weld, and lid 2 and company Knot body 41 can be utilized adhesive etc. to link together on the contrary.

According to this embodiment, union body 41 need not have the area bigger than at least lid 2, but can have area and be equal to Or the elongated shape of the area less than hinge bodies 3.Therefore, molded hinge body 3 and union body 41 are relatively easy to simultaneously, and Lid 2 can mould with other isolation of components ground and independently.Because people can be with centralized Control material during managing in this place And so that the lid 2 of molding will be indeformable, so significantly reduce the difficulty of molding lid 2.

In addition, according to this embodiment, lid 2 and union body 41 be in overlap each other and hinge bodies 3 and union body 41 it Between border near the state that links together.Therefore, the flexure of material is improbable to occur in this region, and by being formed The material of union body 41 and hinge bodies 3 differently bends the union body 41 leading to and hinge bodies 3 due to different flexible degree Separately can be prevented.Therefore, it is possible to provide the file 1 with excellent durability.

(3rd embodiment)

In a second embodiment, union body 41 has elongated plate-like shape.For further enhancing in hinge bodies 3 and union body Between border near file durability, can be using having the post with notch in approximate U shape section as shown in Figure 5 Shape union body 42.Specifically, union body 42 has base plate 421, is set to the vertical plate 422 almost vertical with base plate, Yi Jicong Vertical plate extends and has the upper plate 423 of the shape being nearly parallel to base plate, and has the section of approximate U shape.Base plate or on Contact with vertical plate transverse end of plate and vertical plate may be coupled to hinge bodies 3, and the end of lid 2 can be the bottom of with Any one of side towards base plate of the side towards upper plate of plate and upper plate or both connections.In other words, lid is permissible Connect thus being maintained in approximate U shape.When file is thusly-formed, three kinds of materials are between hinge bodies 3 and union body 42 Border is overlapped nearby, and constitute the material of vertical plate arrange along the direction orthogonal with these three materials further so that Durability in this region significantly improves.

(fourth embodiment)

For the file of first embodiment to 3rd embodiment, if lid 2 includes the first lid 21 and the second lid 22 and these lids define protecgulum and bonnet, then hinge bodies 3 form spine under the restrained condition of file.Alternately, As shown in fig. 6, the 3rd lid 23 could be arranged to constitute the part of spine in the almost center in left-right direction of hinge bodies 3 Component.Specifically, the first lid 21 and the second lid 22 can respectively constitute protecgulum and bonnet；File can include by with The material forming the material same type of the first lid 21 and the second lid 22 is made and is had the 3rd lid of elongated shape 23；First axle body 31 and second hinge body 32 can respectively along almost total length with the 3rd lid 23 two in the lateral direction Transverse end connects；And first axle body 31 and second hinge body 32 with the horizontal stroke being connected to the 3rd lid 23 in the lateral direction The first lid 21 and the second lid 22 can be connected to the transverse end holding relative respectively along almost total length in the vertical direction Transverse end, or the transverse end being connected to union body 41,42.

For example, as it is known that a kind of method pocket 5 being formed by ultra-thin sheet material being connected with file to accommodate document etc..? The method is not for having the 3rd lid 23 of part as spine but only having the file of the hinge bodies 3 of spine to be constituted In the case of folder, if hinge bodies 3 are by having low heat resistant and therefore do not fit through welding pocket 5 is connected to its material Make, be then necessary pocket 5 and lid 2,21,22, union body 4,41,42 grades connect, as shown in fig. 7, this is to file 1 The selection of design is applied with restriction.

And, in the case that only hinge bodies 3 constitute spine, if spine's thickness in the lateral direction, i.e. file Thickness, be configured to sufficiently large so that substantial amounts of document to be constrained in file 1, then made due to the high resiliency of hinge bodies 3 The weight obtaining document leads to the position of spine highly unstable.In which case it is preferable that provide that lid is equal on hardness 2,21,22 or the 3rd lid 23 of union body 4,41,42.

Armed with the 3rd lid 23, for example, as shown in Figure 8 and Figure 9, then being easy to will be by by the method for such as welding The multiple pockets 5 made with the material of the material same type constituting the 3rd lid 23 are connected with the 3rd lid 23.And although It is shown without, but also by the method for such as welding, the loose-leaf binder being made up of analog material and the 3rd lid 23 can be connected Connect, or metal binder clips are attached to serve as file (such as so-called thickness file, its wide in the lateral direction and need There is high durability and to accommodate substantial amounts of object) spine the 3rd lid.3rd lid 23 can be used for the first to 3rd embodiment Any one of in embodiment.

As shown in figure 12, in the file that resin cap and spine form wherein, by being formed from being used as tree The recess that first side of the side of fat sheet material is recessed towards the second contrary side, the long side that thin-walled resin portion can be covered at each Side sets up, thus extending on long side direction.The shape being molded as Figure 12 (a) file so that lid is 7 with respect to ridge In the case that portion 8 turns to the state of Figure 12 (b) from the original state of file, and in the shape being molded as Figure 12 (b) File is so that cover 7 with respect to spine 8 in the case that the original state of file turns to the state of Figure 12 (a), in thin-walled Cause internal stress in resin portion 9.In either case, lid 7 is turned to figure with respect to spine 8 from the original state of file The state of 12 (c) so that contacting with each other in the end of the recess of cap side with the end of the recess of spine side so that The power that side separated from one another to cap and spine is pulled up is from acting on thin-walled resin portion as the contact portion of starting point.When Lid 7 turns to the state of Figure 12 (c) with respect to spine 8 from the state of Figure 12 (a) and subsequently rotates further in same direction When, thin-walled resin portion would become hard to pull.If repeating this action, cap and spine can from thin-walled resin portion from.

Contrastingly, the file 1 of each embodiment of the present invention absorbs internal stress by high resiliency hinge bodies 3. And, the object that file 1 is easy in being contained in file 1 is maintained at the situation between the first lid 21 and the second lid 22 Under from the first lid 21 state transformation almost parallel each other with the second lid 22 to a lid with respect to another lid Rotate and the first lid 21 and the second lid 22 define approximate 180 degree angle state, and pass through this state, to lid Through rotate further in same direction and the first lid 21 and the second lid 22 overlapping thus in the thing being contained in file The state that the bottom of body contacts with each other, as shown in Figure 10.

In short, the file 1 of each embodiment of the present invention allows a lid easily to turn with respect to another lid Dynamic approximate 360 degree.For example, as shown in figure 11, user 6 while grasping file 1 only assume file folder 1 in institute about In the case of the specific page of document of bundle, realize same action with the existing file folder worked as using being only capable of being opened to about 180 degree When compare, it can be avoided that assuming the page with page to be presented next-door neighbour, and will treat to be divided equally by the region of the file holding.Cause This, file 1 is extremely user friendly.

For example, polypropylene can be used as the first material.It is widely used in stationery and plastic components, this synthetic resin has such as The lid of the restrained file of document that high intensity and non-hygroscopic characteristic and being suitable for wherein is made up of multi-disc paper. However, the first material is not limited to this resin.On the other hand, for example, thermoplastic elastomer (TPE) can be used as the second material.This synthetic resin There is the elasticity of rubber like and therefore suitable as the material needing the frequently hinge bodies 3 of 360 degree of rotation.However, because Elastomer is not suitable for the technique of such as welding due to its low heat resistant, so using the 3rd lid 23 being in some cases Preferably.
