Technical Field
[0001] This technical solution relates to the field of folder technology, and specifically refers to a type of folder. Background Technology
[0002] A folder is a container used to categorize, store, and manage files or documents. It refers to a clip that can hold files, provides a hierarchical structure, and groups related information to facilitate quick searching, access, and maintenance by users.
[0003] The existing folder usage process is as follows: First, the files are placed on the solid PP sheet. The files are relatively soft, and the solid PP sheet, with its sufficient strength, can effectively support and protect the files, preventing them from creases or damage during storage. The solid PP sheet is connected to a transparent PP sheet made of plastic film, which can block dust and other dirt from getting in. Then, the solid PP sheet is inserted into the clamping port of a clamping bar along its side. The end of the clamping bar clamps the upper and lower surfaces of the end of the solid PP sheet, so that the solid PP sheet presses the files firmly and fixes them in place.
[0004] When the above folder contains a small number of files (such as a single file), the overall thickness of the solid PP sheet and the file is small, resulting in a weak clamping force of the clamping rod on the solid PP sheet. The solid PP sheet is easy to detach from the open end of the clamping rod, resulting in poor file fixation. This needs to be improved. Summary of the Invention
[0005] This technical solution aims to improve the poor stability of existing folders when containing a small number of files, and provides a new folder solution.
[0006] The purpose of this technical solution is achieved as follows:
[0007] A folder, comprising:
[0008] A package used to hold documents;
[0009] A clamping rod is movably disposed relative to the encapsulation component. The clamping rod is provided with a clamping groove that extends through its two opposite ends along the length of the clamping rod.
[0010] At least one elastic clip is movably disposed within the clamping groove. The elastic clip has a first spring piece and a second spring piece, and an insertion cavity is formed between the first spring piece and the second spring piece. The edge of the package is movably disposed within the insertion cavity. The first spring piece has a first abutment portion protruding into the insertion cavity, and the second spring piece has a second abutment portion protruding at a position corresponding to the first abutment portion.
[0011] The elastic clip moves between a first position and a second position within the clamping groove. When the elastic clip is in the first position, the first and second springs are in an open state, and the edge of the package can be positioned between the first and second contact parts. When the elastic clip moves to the second position, the first and second springs are close together in a closed state, so that the first and second contact parts cooperate to press against the package and the document.
[0012] With the above technical solution, when a folder is in normal use, the user first pulls the packaging component to move the elastic clip toward the clamping groove. The elastic clip is in the first position. After inserting the file, the user pushes the packaging component in the opposite direction, and the elastic clip immediately snaps back into the clamping groove. The elastic clip is in the second position. During the process of the elastic clip moving from the first position to the second position, the two side walls of the clamping groove simultaneously squeeze the first and second spring pieces together and bring them closer, forcing the first and second contact parts to press against the side of the packaging component embedded in the insertion cavity, thereby pressing the file inside the packaging component. The elastic contact parts on both sides cooperate to adaptively shrink and provide stable clamping even when the amount of file inside the packaging component is small, thereby strengthening the clamping force on the file and improving the clamping stability.
[0013] Preferably, the first contact part and the second contact part are provided as protrusions.
[0014] Through the above technical solution, the contact part one and the contact part two can be in the form of protrusions. The protrusions are made of plastic and are pressed through to press against the package.
[0015] Preferably, the first contact part and the second contact part are configured as spring pieces. The first contact part has a guide surface 1, which is inclined outward in a direction away from the bottom of the insertion cavity. The second contact part has a corresponding guide surface 2, which is inclined in a direction opposite to the first guide surface. The first guide surface and the second guide surface cooperate to make the cavity opening end of the insertion cavity flared outward away from the cavity bottom.
[0016] Through the above technical solution, the flared structure in which the insertion cavity is formed by the relative inclination of the first guide surface and the second guide surface automatically guides the side of the package to slide into the cavity. The two contact parts adaptively contract to generate a uniform clamping force on the package, thereby reducing the risk of jamming and improving the smoothness of package installation.
[0017] Preferably, the inner walls of the clamping groove on both sides near the groove opening have inclined sidewalls, and the inclination direction of the inclined sidewalls causes the groove width of the clamping groove to be narrowed towards the groove opening.
[0018] Through the above technical solution, the inclined sidewall design at the opening of the clamping slot automatically guides the position during the insertion of the elastic clip. The inclined sidewall continuously squeezes the spring pieces on both sides of the elastic clip to retract inward, achieving a seamless connection between the insertion action and the clamping force. This optimizes the clamping response speed and stability in thin document scenarios and improves the smoothness of the elastic clip's insertion and reset in the clamping slot.
[0019] Preferably, the outer walls of the elastic clip on opposite sides are symmetrically recessed with positioning grooves.
[0020] With the above technical solution, when the elastic clip moves outward along the clamping groove, the inclined surfaces of the two inclined side walls continuously press against the outer wall of the elastic clip; until the positioning groove moves to the nearest end between the two inclined side walls, the inclined side walls are embedded in the corresponding positioning groove due to elastic deformation, forming a radial clamping force on the elastic clip, preventing it from completely detaching from the clamping groove.
[0021] Preferably, the package includes:
[0022] A substrate, wherein the substrate is bent into a mounting portion, and a mounting groove is formed on the inner side between the mounting portion and the substrate.
[0023] A facing is disposed on the substrate, the edge of the facing is embedded in the mounting groove, the facing covers the substrate, and an interlayer is left between the facing and the substrate for accommodating documents.
[0024] With the above technical solution, the document is placed in the interlayer between the veneer and the substrate, and the edge of the document is embedded in the mounting groove formed by bending the substrate. The mounting part wraps around the veneer and the side edge of the document to form a box-shaped structure. The mounting part provides a uniform bearing surface to isolate the elastic contact part, so as to avoid the document being directly squeezed, prevent the document edge from being damaged, and improve the protection effect.
[0025] Preferably, the inner wall of the insertion cavity has a defined protrusion corresponding to the positioning groove, and the span between the two defined protrusions is adapted to the thickness of the substrate and the mounting part.
[0026] Through the above technical solution, the protrusion and the rigid contact surface of the substrate share the lateral load of the elastic contact part, reduce the swing of the embedded end of the package in the insertion cavity, and improve the insertion stability.
[0027] Preferably, the veneer is translucent.
[0028] Through the above technical solution and the light-transmitting surface design, users can see and confirm the contents of the documents (such as page numbers / titles) inside the compartment without disassembling the documents. This completely avoids the risk of fatigue failure of the elastic clamping parts and damage to the edges of thin documents caused by repeated opening and closing of the folder, thus improving document retrieval efficiency and durability.
[0029] Preferably, the elastic clip has an empty material slot, which connects the insertion cavity to the outside.
[0030] Through the above technical solution, the design of the empty material groove saves material, while improving the deformation capability of the first and second spring sheets. The spring sheets are more easily compressed and contracted, and the rebound resistance is reduced simultaneously, thus optimizing the smoothness of the spring clamp when pulling out and pushing in.
[0031] Preferably, both the first and second springs are arc-shaped thin-walled.
[0032] The above technical solution increases the sensitivity of elastic deformation and further improves the smoothness of the elastic clamp sliding in the clamping groove.
[0033] The key and beneficial technical effects of this technical solution compared to existing technologies are:
[0034] 1. This technical solution uses a spring clip installed on the package. When the spring clip is inserted into the clamping groove, it squeezes the two side spring pieces together, forcing the elastic contact part to adaptively contract and press against the side of the package, thereby strengthening the clamping force between the package and the document and improving the clamping stability.
[0035] 2. This technical solution uses symmetrical recesses on the outer walls of the elastic clamp on both sides to form positioning grooves. The elastic deformation of the inclined side wall embeds into the grooves to form radial clamping force, which completely eliminates the risk of the elastic clamp accidentally falling off and ensures the operational safety and long-term reliability of the clamping mechanism.

[0044] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings.
[0045] Example 1:
[0046] See Figure 1 and Figure 2 A folder includes a packaging component 1, which includes a substrate 11 and a facing 12. The substrate 11 is preferably made of a material with high hardness (such as PP board). The size of the facing 12 is adapted to the substrate 11. The facing 12 is light-transmitting and is preferably made of a transparent or semi-transparent material, such as acrylic board, frosted board, or transparent PP board. The facing 12 has good flexibility. The end of the substrate 11 is folded back to one side to form a mounting part 9. A mounting groove 10 is formed on the inner side of the facing end of the substrate 11. The edge of the facing 12 is embedded in the mounting groove 10 and fixed to the inner side wall of the mounting part 9 facing the mounting groove 10 by means of adhesive or hot melting. An appropriate amount of documents 100 can be sandwiched between the facing 12 and the substrate 11. The documents 100 are preferably paper documents, and the edges of the documents 100 are placed in the mounting groove 10.
[0047] See Figure 2 , Figure 3 and Figure 4 It also includes a clamping rod 2, the length of which is adapted to the length of the package 1. The clamping rod 2 has a clamping groove 3, which runs through the two opposite ends along the length direction of the clamping rod 2, so that the clamping rod 2 has a corresponding groove along the side wall. The inner walls of the opposite sides of the clamping groove 3 near the groove opening have inclined side walls 8. The inclined directions of the two inclined side walls 8 are matched, so that the groove width of the clamping groove 3 is narrowed towards the groove opening end.
[0048] See Figure 5It also includes elastic clips 4, which can be formed by processing a single piece of material without the need for additional connecting structures. At least one elastic clip 4 is installed. This embodiment shows the case where two elastic clips 4 are provided. Both elastic clips 4 are installed in the clamping groove 3 through the opening of the clamping groove 3, and both are movably set relative to the clamping groove 3. Their moving direction is set in the direction from the bottom of the clamping groove 3 to the opening of the groove. An appropriate gap is left between the two elastic clips 4 to distribute the clamping and fixing of the document 100 at different positions and improve stability.
[0049] The opposite side walls of the insertion cavity 5 are formed with a first spring piece 41 and a second spring piece 42. Both the first spring piece 41 and the second spring piece 42 are preferably arc-shaped thin walls. The first spring piece 41 is provided with a contact part 61 protruding into the insertion cavity 5. Specifically, it is a sheet-shaped spring piece and is formed by bending inward so that the contact part 61 is integrally connected with the first spring piece 41. Similarly, the second spring piece 42 is provided with a corresponding contact part 62. The structure of the contact part 62 is similar to that of the contact part 61. It is integrally connected with the second spring piece 42 by bending inward.
[0050] Each elastic clip 4 has an empty material slot 14. In this embodiment, two empty material slots 14 are shown on the first elastic piece 41. The two empty material slots 14 are spaced apart along the length of the elastic clip 4. Each empty material slot 14 is connected to the insertion cavity 5 to the outside, so as to reduce the material consumption and increase the elastic deformation effect of the first elastic piece 41.
[0051] The first contact part 61 has a guide surface 71, which is set as the end face of the first contact part 61 away from the first spring piece 41. The guide surface 71 is inclined outward in a direction away from the bottom of the insertion cavity 5. The second contact part 62 is set as the guide surface 72 corresponding to the end face of the first guide surface. Its inclination direction is opposite to the first inclination surface. The guide surface 71 and the guide surface 72 cooperate to make the cavity opening end of the insertion cavity 5 flared outward away from the cavity bottom.
[0052] The elastic clip 4 has symmetrically recessed positioning grooves 15 on its opposite outer walls. The inner wall of the insertion cavity 5 has corresponding positioning grooves 15 with protruding limiting protrusions 13. The span distance α between the two limiting protrusions 13 is adapted to the thickness of the substrate 11 and the mounting part 9.
[0053] The end of the elastic clip 4 is inserted into the clamping groove 3. The part of the elastic clip 4 with the positioning groove 15 is at the narrowest end of the clamping groove 3. The lowest points of the inclined side walls 8 on both sides are respectively inserted into the positioning grooves on both sides of the elastic clip 4 to achieve preliminary positioning preparation. At this time, the elastic clip 4 is in the first position, and the first spring piece 41 and the second spring piece 42 are in the open state.
[0054] The document 100 is inserted into the package 1. The end of the package 1 with the mounting part 9 is aligned with the insertion cavity 5 and inserted. During the insertion process, the package 1 will push and squeeze the second contact part 62 and the first contact part 61 to elastically avoid each other until the package 1 is fully inserted. At this time, the two limiting protrusions 13 respectively abut against the mounting part 9 and the upper and lower end surfaces of the substrate 11.
[0055] The elastic clip 4 moves between a first position and a second position within the clamping groove 3, pushing the encapsulation component 1 towards the direction of the clamping groove 3 (or, applying force to push the clamping rod 2 towards the direction of the encapsulation component 1 achieves the same effect). The encapsulation component 1 also moves the elastic clip 4, causing the elastic clip 4 to further engage with the clamping groove 3. During the movement of the elastic clip 4 to the second position, the outer arc surfaces of the first spring piece 41 and the second spring piece 42 on the elastic clip 4 slide along the inclined sidewalls 8 on both sides of the clamping groove 3 and are guided by them. The squeezing action of the inclined sidewall 8 forces the first spring 41 and the second spring 42 to move closer to each other, thereby driving the second contact part 62 connected thereto to cooperate with the first contact part 61 to elastically press against the package 1, forming an elastic clamp and firmly locking the package 1. At this time, the package 1 cannot be easily pulled out from the insertion cavity 5. If it is necessary to remove the document 100, a greater force must be applied to overcome the elastic clamp and pull the package 1 together with the elastic clip 4 out of the insertion cavity 5. The elastic clip 4 moves from the second position to the first position.
[0056] See Figure 6 The number of clamping rods 2 can be set as needed. When multiple clamping rods 2 are installed, they can be arranged at the edges of the encapsulation component 1 according to actual needs. For example, if two or more clamping rods 2 are installed on the same side, the total length of the clamping rods 2 on one side should be less than the length of the edge where it is located to avoid interference affecting normal use. Each clamping rod 2 is provided with at least one elastic clip 4.
[0057] The specific work process of this plan is as follows:
[0058] This technical solution involves pulling the package 1 to move the elastic clip 4 toward the opening of the clamping groove 3. After inserting the document 100, the package 1 is pushed in the opposite direction, and the elastic clip 4 is then inserted back into the clamping groove 3. During this process, the two side walls of the clamping groove 3 simultaneously squeeze the first elastic piece 41 and the second elastic piece 42 to close together, forcing the first contact part 61 and the second contact part 62 to press against the side of the package 1 embedded in the insertion cavity 5, thereby pressing the document 100 inside the package 1. The elastic contact parts on both sides cooperate, so that even when the amount of document 100 inside the package 1 is small, it can still adaptively shrink and provide stable clamping, strengthening the clamping force on the document and improving the clamping stability.
[0059] Example 2:
[0060] A folder, differing from Embodiment 1, has its first contact part 61 and second contact part 62 set as protrusions made of plastic. Correspondingly, a groove 1 is recessed on the side face of the substrate 11 away from the mounting part 9, and a groove 2 is provided on the side wall of the mounting part 9 away from the substrate 11 corresponding to the groove 1. When the edge of the package 1 is placed between the first spring and the second spring, the first contact part 61 and the second contact part 62 are respectively fitted into the groove 1 and the groove 2. The specific implementation method is similar to that in Embodiment 1, and will not be described in detail here.
[0061] Example 3:
[0062] See Figure 7 A folder, differing from Embodiment 1 in that the substrate 11 and the facing 12 are integrally connected. The facing 12 has a folded edge 200, which is formed by cutting the facing 12 on its inner side near the connection point with the substrate 11. The folded edge 200 is roughly rectangular in shape and folds towards the substrate 11. The function of the folded edge 200 is similar to that of the mounting part 9 described above. The folded edge 200 leaves a mounting opening 300 in the original position of the facing 12. This mounting opening 300 is used to install a pull rod 2 and a spring clip 4. The length needs to be less than or equal to the length of the mounting opening 300; when the elastic clip 4 is in the first position, the first spring piece 41 and the second spring piece 42 are in the open state, and the document 100 can be taken out; when the elastic clip 4 is in the second position, the first spring piece 41 and the second spring piece 42 are in the closed state, and the first contact part 61 and the second contact part 62 cooperate to press the package 1 and the document 100 together. In this embodiment, it is shown that the first contact part 61 and the second contact part 62 respectively abut against the opposite two end faces of the substrate 11 and the folded edge 200. The specific implementation method is similar to that in embodiment 1, and will not be described in detail here.
