Description

Technical Field

[0001] The utility model relates to the technical field of stationery, in particular to a loose-leaf folder with a new structure. Background Art

[0002] As an indispensable stationery in office and study, folders are mainly used for the classification, organization and storage of documents, and also for the management of examination papers. Figure 1 As shown, it includes a folder shell 1 that can be opened, and a plurality of stacked transparent file pockets 11, which are ultrasonically welded to the side of the inner side of the folder shell 1 on one longitudinal edge 12. The file pocket 11 is used to insert a single sheet of paper, usually in A4 or A3 size. When it is A3 size, it can be folded in the middle and folded together with the folder shell to one side to form an A4 size. The disadvantage of this structure is that since these file pockets are stacked without spacing on one side, after most of the file pockets are filled, the thickness of the fixed side cannot meet the requirements of placing a large number of files because it is limited by the fixed side and cannot flexibly replace the content. In order to solve this technical problem, there is also a loose-leaf folder in the prior art, such as Figure 2 The structure shown, in order to accommodate a larger number of loose-leaf document bags, uses a binder 13 fixed in the folder shell 1, and the loose-leaf document bag 14 is detachably set in the folder shell 1 through the binder 13. Although such a structure can accommodate more loose-leaf document bags 14, it also results in its thickness being the thickness of one binder 13 plus the thickness of three layers of folder shell 1, and because the folder shell is arched when it is flipped and merged in the middle, and there is a flipping and merging covering at the edge merging position, the actual use feels heavier, and no matter how many loose-leaf documents are therein, its thickness does not change, making it difficult to achieve a lightweight use effect, and the assembly and production costs are high. Summary of the invention

[0003] The technical problem to be solved by the embodiment of the utility model is to provide a loose-leaf folder with a new structure, which can make the folder lighter and thinner and effectively reduce the production cost.

[0004] In order to solve the above technical problems, an embodiment of the utility model provides a new type of loose-leaf folder, including a folder shell, a plurality of loose-leaf pages, a cover, and a binder. The folder shell, loose-leaf pages, and cover have a plurality of clamping holes in the longitudinal direction of the same side, and the binder is clamped in the clamping holes outside the side. The folder shell includes a bottom page and a hinge connected as a whole, the bottom page corresponds to the width of the cover, the connection between the hinge and the bottom page has a fold mark, the width of the hinge is smaller than the width of the cover, the cover is stacked on the top of the loose-leaf pages, and the hinge can be opened and connected to the surface of the cover.

[0005] A further preferred solution is to further include a loose-leaf card, the bottom of which is fixedly arranged on the bottom edge of the base page, for clamping the loose-leaf card on the base page.

[0006] A further preferred solution is that a plurality of folds are punched on the lower portion of the loose-leaf card to adjust the thickness of the card according to the number of the loose-leaf cards.

[0007] A further preferred solution is that the hinge at least partially covers the loose-leaf card.

[0008] A further preferred solution is that there are at least two fold marks between the hinge and the bottom page.

[0009] A further preferred solution is that the hinge and the cover surface are openably connected by means of snaps or Velcro.

[0010] A further preferred solution is that the binder is a five-hole binder, and there are two of them, which are clamped in the clamping holes at the upper and lower parts of the side.

[0011] A further preferred solution is that the loose-leaf document bag is an A4 or A3 size loose-leaf document bag.

[0012] The implementation of the embodiments of the utility model has the following beneficial effects: the utility model simplifies the assembly process of the folder through design innovation, and the bottom page, loose-leaf pages and cover of the folder shell are clamped together by a binder on the side of the clamping hole, and the binder used is independent and not connected to other structures as a whole, so it is more flexible in use. The folder shell is only turned up on one side, so its thickness is thinner than the structure of the prior art, and the capacity of the loose-leaf pages can also be clamped as needed. In the generation and assembly, it is only necessary to align the folder shell, loose-leaf pages and cover on the clamping hole, and operate the binder to clamp. BRIEF DESCRIPTION OF THE DRAWINGS

When a component is considered to be "connected to" another component, it may be directly connected to the other component or there may also be a component centered. When a component is considered to be "set on" another component, it may be directly set on the other component or there may also be a component centered. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0021] like Figure 1As shown, a new type of loose-leaf folder structure of the present embodiment includes a folder shell 2, a plurality of loose-leaf pages 3, a cover 4, and a binder 5. The loose-leaf pages 3 and the cover 4 are movably connected to the folder shell 2 through the binder 5. In order to achieve this purpose, the folder shell 2, the loose-leaf pages 3, and the cover 4 are provided with a plurality of clamping holes 22 in the longitudinal direction of the same side edge 21, such as 26 clamping holes are set by punching and shearing, and the binder 5 is clamped in the clamping holes from the outside of the side edge 21.

[0022] Since the main body of the binder 5 is located on the outside of the side 21, the binder does not have a substantial effect on the thickness after clamping, and the binder is bound together with the file shell 5 and the side of the cover 4. Therefore, the cover 4, the loose-leaf 3, and the file shell 2 on the side 21 are tightly stacked together, and their thickness at this position is equivalent to the number of loose-leaf 3 actually clamped.

[0023] In this embodiment, the binder can be selected as a whole binder, which is clamped on the clamping hole 22, such as the binder disclosed in Chinese Patent Publication No. CN307035758S, or the whole binder is used to clamp the clamping holes 22 of the upper and lower parts, such as the binder disclosed in Chinese Patent Publication No. CN305997540S. In this embodiment, the preferred implementation method is to use two five-hole binders, which are clamped in the clamping holes of the upper and lower parts of the side, such as the five-hole binder disclosed in Chinese Patent Publication No. CN212708642U. In this way, when in use, the loose-leaf therein can be conveniently disassembled. Therefore, the specific structure of the binder is not described in detail in the embodiment of the utility model.

[0024] The folder shell 2 includes a bottom page 23 and a hinge 24 connected together. The connection between the hinge 24 and the bottom page 23 has a fold mark 25. The fold mark 25 is used to allow the hinge 24 to be folded from the bottom to the front. The bottom page 23 corresponds to the width of the cover 4, so that the cover can be covered within the width range of the bottom page 23 and can be covered therein by folding the hinge 24. There are at least two fold marks 25, which are vertically stamped at the connection between the hinge 24 and the bottom page 23. In the present embodiment, four fold marks are preferably provided to accommodate loose-leaf clamps of greater thickness, but the present invention is not limited thereto.

[0025] In the present invention, the width of the hinge 24 is smaller than the width of the cover 4, so that the folder shell 2 only covers the loose-leaf 3 from back to front on the right side. Of course, in order to achieve a slimmer feel, the width of the hinge 24 does not exceed 1 / 2 of the width of the cover 4.

[0026] The cover 4 is used to be stacked on the top layer of the loose-leaf 3 to protect the loose-leaf thereunder. The cover 4 can be a transparent or translucent plastic page, or a plain leather material.

[0027] The hinge 24 is openably connected to the surface of the cover 4, such as by setting snaps or Velcro to form the openable connection. In this embodiment, Velcro 26 is pasted on the corresponding positions of the hinge 24 and the cover 4 to form the openable connection.

[0028] In this embodiment, the loose-leaf 3 can be loose-leaf paper of A3 or A4 size, or can be a loose-leaf document bag of A4 or A3 size. When it is of A3 size, it can be folded at the folding mark.

[0029] In order to prevent the loose-leaf 3 from sagging out of the bottom edge of the bottom page 23 during the process of taking and placing, a loose-leaf card 6 is also provided on the bottom edge of the bottom page 23. The bottom edge of the loose-leaf card 6 is connected to the bottom edge of the bottom page 23 by ultrasonic welding, and a clampable loose-leaf is formed between the main body of the loose-leaf card 6 and the bottom page 23.

[0030] A plurality of folds 61 are punched on the lower portion of the loose-leaf card 6 to adjust the thickness that can be held according to the number of loose-leaf pages.

[0031] In this embodiment, the hinge 24 at least partially covers the loose-leaf card 6, and the loose-leaf card 6 is arranged at the center of the bottom edge of the bottom page 23 or at the right edge, so that the hinge 24 can press the loose-leaf card 6 on the loose-leaf when it is closed to the front, thereby improving its holding effect on the loose-leaf.

[0032] The utility model is characterized in that the structure on the left side has only the bottom page 23, the loose-leaf 3, and the cover 4 stacked in sequence, and the main body of the binder is located outside the left side to clamp the clamping holes of the three, so its thickness is only the thickness of the three, and on the left side, there is no need to make the file shell wrap forward on the left side to increase the thickness, and on the right side, only the hinge 24 is turned forward and closed, and the thickness is only the thickness of two layers of file shells, and the binder is not covered therein, so its thickness is naturally thinner than the existing method.

[0033] The above description is only a preferred embodiment of the utility model and does not impose any form of limitation on the utility model. Any ordinary technician in the industry can smoothly implement the utility model as shown in the drawings of the specification and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the utility model are still within the protection scope of the technical solution of the utility model.
