Description

Technical Field

[0001] The present invention relates to a document hole clip, and more particularly to a multi-ring document hole clip for a loose-leaf notebook. Background Art

[0002] A loose-leaf binder can be used to fix papers. Its structure mainly includes a front cover, a back cover, and a hole clip between the front cover and the back cover. The hole clip includes a plurality of coils or semi-rings for papers with holes to pass through each coil or ring and be fixed in the loose-leaf binder. Common hole clips are divided into closed coils and switchable semi-ring loops. The former, the closed coil (such as a spiral ring binder), has the characteristic of flexible operation, can be folded 360 degrees, is convenient for single-handed operation, and requires little space. However, since the coil is in a closed state after the finished product is completed and cannot be opened, papers cannot be added or replaced arbitrarily. The latter, the switchable semi-ring loop (such as a loose-leaf ring binder), because its semi-ring loop is designed to be openable and closable, users can arbitrarily take out and replace the inner pages. However, because the switch structure is usually wider and larger, it lacks the flexible operation characteristic of the closed coil, cannot be folded backward, is difficult to hold with one hand during use, and usually requires a larger operation space. In addition, this type of design usually requires both hands to press the switches at both ends to open, which is difficult to operate. When closing, several coils need to be pressed simultaneously to offset the internal spring tension, and then it automatically springs back to the closed state by its spring tension, often resulting in noise generation and the possibility of pinching. In addition, due to the manufacturing process or the problem of material aging after long-term use in the semi-ring design of most clamps, gaps are often generated at the joints, resulting in paper jamming, making it difficult to turn pages or causing damage to the holes of the inner pages. Summary of the Invention

Detailed implementation manners

[0047] In order to solve multiple problems of current loose-leaf hole clips, the inventor has conducted research and development for many years to improve the drawbacks of existing products. Subsequently, how the present invention achieves the most efficient functional requirements with a multi-ring document hole clip will be introduced in detail.

[0048] Please refer to Figures 1 to 3 , Figure 1 It is a three-dimensional external view schematic of the multi-ring document hole clip of the present invention. Figure 2 It is a three-dimensional exploded view schematic of the multi-ring document hole clip of the present invention. Figure 3It is a partial three-dimensional exploded view of the multi-ring document hole clip of the present invention. As shown in the figure, in the embodiment of the present invention, for a loose-leaf notebook having multiple loose leaves, the multi-ring document hole clip 100 includes a positioning locking pin 110, a movable central spindle body 120, a first bracket body 130, a second bracket body 140, a C-shaped ring 150 and a bottom cover 160. One side of the movable central spindle body 110 has a limiting portion 129, and its function will be described later. The main body of the movable central spindle body 120 is formed by alternately arranging and connecting a plurality of cylinders 122 and a plurality of rectangular bodies 124. In one embodiment, the entire central spindle body 120 can be made by an integral molding method, but this is not a limitation. Among them, the main body of the movable central spindle body 120 also has a rectangular body 126 with a shorter length L4 (as Figure 2 shown, compared with other rectangular bodies 124). In addition, the top 128 of the body of the movable central spindle body 120 is connected to the positioning locking pin 110, and the surfaces of the rectangular bodies 124 beside the top 128 of its body have a first positioning groove TA1 and a second positioning groove TA2, and their functions will be described in the subsequent paragraph about the C-shaped ring. And the top 128 of the body can be a spiral body top in the embodiment of the present invention, but this is not a limitation. It should be understood that in the embodiment of the present invention, the positioning locking pin 110 can be used to drive the linear movement of the movable central spindle body 120. Next, it will be further described in detail.

[0049] The main body of the first bracket body 130 has a plurality of first semi-ring loops 132A and a plurality of second semi-ring loops 132B, which are alternately arranged at equal distances on the first bracket body 130. And the first bracket body 130 has a plurality of first hollow bodies 134 and a top hollow body 138, which are arranged on the first bracket body 130 at appropriate intervals. Among them, the outer shapes of the plurality of first hollow bodies 134 and a top hollow body 138 are both round outside and square inside, and the rectangular holes completely penetrate the cylinders. And the first bracket body 130 also has a first hollow body 136 with a shorter length L5 (as Figure 2 shown, compared with other first hollow bodies 134). In addition, it should be noted that a C-ring device groove TA3 is provided between the top hollow bodies 138 of the first bracket body 130. In one embodiment, the C-shaped ring 150 is set and embedded in the C-ring device groove TA3 inside the top hollow body 138, and the C-shaped ring 150 performs a positioning action by being clamped in the first positioning groove TA1 or the second positioning groove TA2. The above-mentioned C-shaped ring 150, first positioning groove TA1 and second positioning groove TA2 are used for positioning to prevent the movable central spindle body 120 from deviating from the preset position under non-artificial operation, but this is not limited to this. In other embodiments, similar components can also be used to achieve the same effect, such as the setting of magnets or bumps.

[0050] In addition, regarding the second bracket body 140, the second bracket body 140 and the first bracket body 130 are substantially complementary and symmetric. The second bracket body 140 also has a plurality of first half-ring loops 142A and a plurality of second half-ring loops 142B which are arranged on the second bracket body 140 at equal intervals and staggered with each other. And there are a plurality of second hollow bodies 144 and a bottom hollow body 149 on the second bracket body 140 which are arranged on the second bracket body 140 at appropriate intervals. Among them, the outer shapes of the plurality of second hollow bodies 144 and the bottom hollow body 149 are both round on the outside and square on the inside, and the rectangular holes completely penetrate the cylinders. And there is also a second hollow body 146 with a shorter length L6 on the second bracket body 140 (as Figure 2 shown, compared with other second hollow bodies 144). In addition, it should be noted that the lower part of the rectangular hole of the bottom hollow body 149 of the second bracket body 140 is connected to a circular limiting space for accommodating and restricting the moving stroke of the limiting part 129.

[0051] When the multi-ring document clip 100 of the present invention is in a closed state, when the first half-ring loop 132A on the first bracket body 130 engages with the second half-ring loop 142B on the second bracket body 140, a complete ring will be formed, or when the second half-ring loop 132B on the first bracket body 130 engages with the first half-ring loop 142A on the second bracket body 140, a complete ring will be formed. And the engaging manner and the number of complete rings are not used to limit the embodiments of the present invention. It should be noted that in the embodiments of the present invention, through the symmetric engagement or joining of the first bracket body 130 and the second bracket body 140, the plurality of first hollow bodies 134 and the plurality of second hollow bodies 144 will engage with each other to form a continuous hollow body, just like forming a long tunnel. For example, the second hollow body 144 is placed between two first hollow bodies 134. Then, the movable central spindle body 120 is inserted and assembled inside the continuous hollow body to serve as the common central rotating shaft of the first bracket body 130 and the second bracket body 140. The outer shape of the continuous hollow body is round on the outside and square on the inside, and the overall length of the movable central spindle body 120 is greater than the length of the continuous hollow body. Finally, the positioning lock pin 110 is installed at the top of the movable central spindle body 120, and then the bottom cover 160 is installed on the bottom hollow body 149, and the multi-ring document clip 100 of the embodiments of the present invention can be completed. In addition, the length L1 of the rectangular body 124 of the movable central spindle body 120 is less than the length L2 of the first hollow body 134, so that the hollow body can completely accommodate the corresponding rectangular body.

[0052] It is worth mentioning that the above description of the present embodiment uses the appearance shapes of the rectangular body 124 and the first and second hollow bodies 134 and 144 of the rectangle as an example. However, in other embodiments, the original rectangular body and the rectangular hollow body can be triangles, polygons, stars or other shapes to match each other. For example, a triangular body and a triangular hollow body, or a star-shaped body and a star-shaped hollow body.

[0053] Next, the operating mechanism of the multi-ring document hole clip 100 according to the embodiment of the present invention will be further described in detail.

[0054] Please refer to Figures 4 to 8 , Figure 4 which is a schematic diagram of the locked state of the multi-ring document hole clip of the present invention. Figure 5 which is of Figure 4 the present invention. Figure 6 which is a schematic diagram of the unlocked state of the multi-ring document hole clip of the present invention. Figure 7 which is of Figure 6 the present invention. Figure 8 which is a schematic diagram of the opened ring state after unlocking the multi-ring document hole clip of the present invention. As Figure 4 and Figure 5 shown, when the user pushes the positioning lock pin 110 back, the positioning lock pin 110 will also drive the movable center spindle body 120 to move. At this time, the C-shaped ring 150 is engaged with the first positioning groove TA1. Next, a part of the plurality of rectangular bodies 124 on the movable center spindle body 120 will move from the inside of the plurality of first hollow bodies 134 into the plurality of second hollow bodies 144 respectively. At this time, both ends of each rectangular body are respectively engaged into the rectangular holes of the corresponding first hollow body 134 and the second hollow body 144, preventing the relative rotation of the corresponding first hollow body 134 and the second hollow body 144, thereby entering the locked state, as Figure 4 and Figure 5 shown, and further preventing the plurality of first half-ring circles 132A (or 142A) and the plurality of second half-ring circles 132B (or 142B) from rotating and moving to open or close the ring. Simply put, since the rectangular bodies 124 are respectively located inside the first hollow body 134 and the second hollow body 144, the multi-ring document hole clip 100 is locked in the closed state to ensure that the cover and the inner page paper of the notebook will not fall apart. At this time, the user cannot open the ring to add or replace loose-leaf paper. The locking method only requires a pushing action of the positioning lock pin. The user operation is simple and has high stability. Therefore, when the user reads or takes loose-leaf notes, it can bring the effect of convenient use. In addition, since the backbone of the movable center spindle body 120 is thinner than that of the background technology, the user can fold the notebook back nearly 360 degrees when using it, which is convenient for single-handed holding and significantly improves the flexibility of use.

[0055] Finally, as Figures 6 to 8 shown, when the user pulls up the positioning lock pin 110, the positioning lock pin 110 will also drive the movable center spindle body 120 to move upward. At this time, it should be noted that since there is a limiting portion 129 on the bottom side of the movable center spindle body 120, it will contact the abutting portion 1491 when pulled up, and further prevent the movable center spindle body 120 from being completely pulled out (please refer to Figure 2 and Figure 6 ). At this time, the C-shaped ring 150 will snap into the second positioning groove TA2. At the same time, the plurality of rectangular bodies 124 on the movable center spindle body 120 will respectively completely disengage from the second hollow body 144 and completely move into the plurality of first hollow bodies 134, so that the multi-ring document hole clip 100 enters the unlocked state, and further enables the plurality of first half-ring circles 132A (or 142A) and the plurality of second half-ring circles 132B (or 142B) to rotate to open or close the ring. In other words, when the positioning lock pin 110 is pulled up by the user and drives the movable center spindle body 120 into the unlocked state, the user can manually rotate the first bracket body 130 and the second bracket body 140 relative to the movable center spindle body 120 respectively to open or close the ring (at this time, the first bracket body 130 cannot rotate relative to the movable center spindle body). Next, the user can normally open the ring to add or replace the loose-leaf paper, and its unlocking operation method is simple and has high stability. Here, it should be noted that the materials of the positioning lock pin 110, the movable center spindle body 120, the first bracket body 130, the second bracket body 140, the C-shaped ring 150, and the bottom cover 160 in the embodiments of the present invention are not limited to any material or single material. In one embodiment, the material can be recycled material; in another embodiment, the material can be stainless steel. The embodiments of the present invention are not limited by any material.

[0056] The closed state or the unlocked state of the present invention is all carried out according to the above working principle, and as long as it conforms to the above working principle to carry out the closing or unlocking movement, it belongs to the equivalent scope of the patent application scope of the present invention.

[0057] Next, please refer to Figure 9 and Figure 10 , Figure 9 which is the front view of the closed state of the multi-ring document hole clip of the present invention. Figure 10It is a front view of the open state of the multi-ring document hole clip of the present invention. As shown in the figure, for the multi-ring document hole clip 100 disclosed in the present invention, the user can control the unlocking and locking states of the movable central spindle body 120 by manually operating (pulling or pushing) the positioning lock pin 110, and then operate the opening and closing of each ring. It should be noted that multiple first half rings 132A (or 142A) are semicircular and their tops are in a shape with a convex upper part and a concave lower part; in addition, multiple second half rings 132B (or 142B) are semicircular and their tops are in a shape with a concave upper part and a convex lower part (corresponding and matching the convex upper part and concave lower part of the first half rings 132A (or 142A)). As Figure 1 and Figure 9 shown, when the user closes the hole clip and pushes the positioning lock pin 110, the movable central spindle body 120 is in a locked state, and the first half rings 132A on the first support body 130 and the second half rings 142B on the second support body 140 are correspondingly clamped with each other to form a complete ring, and the second half rings 132B on the first support body 130 and the first half rings 142A on the second support body 140 are correspondingly clamped with each other to form a complete ring. In addition, as Figure 8 and Figure 10 shown, when the user pulls up the positioning lock pin 110, the movable central spindle body 120 is in an unlocked state, and at this time, the originally closed multiple first half rings 132A (or 142A) and multiple second half rings 132B (or 142B) can be freely opened or closed.

[0058] It should be further noted that on one side of the first support body 130, the position layout of its half rings is in an alternating pattern of first half ring 132A, second half ring 132B and first half ring 132A in sequence. On the other side of the second support body 140, the position layout of its half rings is in an alternating pattern of second half ring 142B, first half ring 142A and second half ring 142B in sequence. Each complete ring is symmetrically clamped and sealed by the first half ring 132A (or 142A) and the second half ring 142B (or 132B), and each complete ring is that the convex body of the first half ring 132A (or 142A) is clamped and sealed to the concave body of the second half ring 142B (or 132B), and the concave body of the first half ring 132A (or 142A) is clamped and sealed to the convex body of the second half ring 142B (or 132B).

[0059] Please also refer to Figures 11 to 14 , Figure 11 which is a partial schematic diagram of the multi-ring document hole clip of the present invention. Figure 12 which is a schematic diagram of the action of the loose-leaf application of the multi-ring document hole clip of the present invention. Figure 13 is Figure 12 a partial schematic diagram of the first state of the page-turning action.Figure 14 is Figure 12 a partial schematic diagram of the second state of the page-turning action of. From Figure 11 it can be seen that in the embodiments of the present invention, if the multi-ring document hole clip 100 due to long-term use or other factors, causes at least one group of first half-ring loops 132A (or 142A) and the second half-ring loop 142B (or 132B) to not be able to be completely snapped and sealed (unable to form a complete ring), resulting in a gap distance d (when the multi-ring document hole clip 100 is in the closed state), so in the background art, when the user uses a notebook with a traditional document hole clip and turns the page, it is easy to have the problem of loose-leaf paper jamming.

[0060] Furthermore, from Figures 12 to 14 it can be seen that in Figure 13 when the user turns the loose-leaf paper P, due to the above reasons, the loose-leaf paper P is very likely to fall into the groove in the area RB. The opening distance of the groove is the gap distance d, but because the multi-ring document hole clip 100 is an interleaved upper and lower half-ring layout, so the loose-leaf paper P in other areas RA or RC will be blocked by the upper convex body of the adjacent first half-ring loop 132A or the possibility of restricting the downward movement of the loose-leaf paper is restricted to prevent the loose-leaf paper from jamming. After that, in Figure 14 when the user continues to turn the above-mentioned loose-leaf paper P, due to the above reasons, the loose-leaf paper P is very likely to fall into the groove in the area RD or RF. The opening distance of the groove is the gap distance d, but because the multi-ring document hole clip 100 is an interleaved upper and lower half-ring layout, so the loose-leaf paper P in other areas RE, RG and RH will be blocked by the upper convex body of the adjacent first half-ring loop 132A or the possibility of restricting the downward movement of the loose-leaf paper is restricted to prevent the loose-leaf paper from jamming. Simply put, through the special half-ring loop layout of the embodiments of the present invention, it is possible to prevent and avoid loose-leaf paper jamming. Figures 13 to 14 The multi-ring document hole clip of is related to the actions applied to a notebook with multiple loose-leaf pages.

[0061] In summary, the multi-ring document hole clip for a loose-leaf notebook with multiple loose-leaf pages disclosed by the present invention can bring the following effects:

[0062] 1. High security and high stability;

[0063] 2. Make it convenient for the user to operate the switch and replace the inner pages;

[0064] 3. The page turning is smooth, and it can effectively avoid the tearing and damage of the paper holes, and can extend the service life of the notebook;

[0065] 4. The notebook is easy to fold backward and is convenient to hold with one hand, with high flexibility in use;

[0066] 5. The structure is relatively simple, which can reduce the process and cost, and reduce the failure rate.

[0067] The above description is illustrative rather than restrictive to the present invention. Those of ordinary skill in the art understand that many modifications, variations or equivalents can be made without departing from the spirit and scope defined by the claims, and all of them will fall within the protection scope of the present invention.
