Description

Technical Field

[0001] An elastic clip, a clip handle, and a clip belong to the field of stationery, and particularly relate to a clip that strengthens the clamping force of the clip handle device. Background Technology

[0002] Patent CN217827186U discloses a book clip that uses increased handle length as the main technical means to maintain the cuboid shape of the books and documents, allowing them to be stacked upright. However, increasing the handle length significantly increases the cost of the clip, limiting its widespread application. How to maintain the cuboid shape of books and documents for stacking upright remains a pressing problem to be solved. Summary of the Invention

[0003] In existing technologies, a clamping interface is typically provided inside the hinge hole of the clamping handle. The clamping handle is either in a prying state, tightly against the clamping part, or in a retracted state, tightly against the data. The clamping interface includes a triangular state-transition protrusion, which achieves the state transition by the elastic deformation of the clamping handle. Increasing the sharpness of the state-transition protrusion can increase the clamping force of the clamping handle. However, the increase in force is limited, and it also increases the difficulty of transitioning between the two states.

[0004] In patent application number 202322259264.6, the height of the table-mounting clamp was increased, and a portion for receiving clipped documents was added at the outer end of the table-mounting clamp with the hinge hole. The table-mounting clamp portion for receiving clipped documents is structurally relatively empty, making it possible to specifically design a handle locking interface here to enhance the clamping force of the handle locking interface. Based on the above research, the applicant developed a clamp piece that separates the handle hinge device from the handle locking device, thereby specifically enhancing the clamping force of the handle locking device, and a clamp using this clamp piece, the specific solution of which is as follows: Technical Solution 1: An elastic clip, formed by bending a sheet along two parallel bending ridges, includes two clips located on both sides and a connecting part located in the middle connecting the two clips. The angle between the plane of the clips and the plane of the connecting part is less than 90 degrees. Each clip includes a hinge shaft that defines a handle and rotates therein to allow the handle to include a handle hinge device in a prying state and a retracted state, and a handle locking device that locks the handle in the retracted state. Optionally, the handle hinge device of at least one clip is separated from the handle locking device, with the handle hinge device being relatively closer to the bending ridge and the handle locking device being relatively closer to the opening and closing end of the clip.

[0005] Typically, elastic clips are made by bending sheets or by hot-melt molding. Sheet bending primarily uses steel, such as manganese steel, while hot-melt molding mainly uses plastic. Current technology rarely uses plastic hot-melt molding, primarily because plastic's hardness or toughness is insufficient for use as a professional clip.

[0006] The clamp handle hinge device includes a cylindrical hinge shaft receiving cavity, with its axis parallel to the bend ridge. The hinge shaft of the clamp handle is confined within the hinge shaft receiving cavity of the hinge device. When the clamp handle rotates to a position close to the bend ridge, it is in a prying state. When the clamp handle rotates in the opposite direction to a position close to the clamping part, it is engaged in the clamp handle engaging device and is in a retracted state. In the retracted state, the clamp handle is also close to the book or document.

[0007] Patent CN108973410A discloses a pry-type side-rotating clamp, in which the clamp handle prying device and clamp handle storage device are separate. The clamp handle prying device is located at the opening and closing end of the clamp, and the clamp handle storage device is located in the middle of the clamp. The clamp handle storage device is a hinged component; relying on its rotational freedom, it is in a prying state when engaged with the clamp handle prying device, and in a stored state when disengaged from the prying device. After the clamp handle is stored, it does not protrude and rest against the material, thus failing to solve the problem of maintaining the cubic shape of the material.

[0008] In this design, the clamping device is located relatively close to the opening and closing end of the clamp, and the clamping hinge device is located relatively close to the bending ridge. This layout, in which the clamping device and the clamping hinge device are separated, not only preserves the characteristic of the clamping handle being close to the book and documents for storage, but also lays the foundation for optimizing the clamping device and increasing the clamping force of the clamping device, which is the inventive point of this design.

[0009] Beneficial effects: It frees the clamping device from the limitations of the clamping hinge device, laying the foundation for increasing the clamping force.

[0010] Technical Solution 2: As a preferred embodiment of Technical Solution 1, the clamping part of the clamping handle hinge device and the clamping handle snapping device includes a pair of frame-shaped cuts facing each other but not connected, and also includes a tongue formed by the frame-shaped cuts separating from the clamping part, and a tongue connecting part connecting the tongue and the clamping part. The clamping handle snapping device includes a cylindrical vertical handle receiving cavity with open ends and a vertical handle inlet and outlet at the top of the vertical handle receiving cavity for the vertical handle to enter the vertical handle receiving cavity after rotating around the rotation axis of the clamping handle. The vertical handle receiving cavity and the vertical handle inlet and outlet are formed by the clamping part between the two tongues after being bent towards each other.

[0011] The frame-shaped cuts face the connecting part of the orifice, opposite to the orientation of the orifice. Alternatively, the orifices can face each other, causing the frame-shaped cuts to merge into an H-shape. This H-shaped cut poses a significant challenge for materials with poor ductility. Frame-shaped cuts facing each other but not connected become a preferred solution. Corresponding to the two vertical handles, there are two sets of paired frame-shaped cuts, forming orifices that constitute two cavities for receiving the vertical handles.

[0012] When the vertical handle portion of the clamping handle is pressed, it pushes open the tongue of the clamping handle engaging device and enters the vertical handle receiving cavity from the vertical handle inlet and outlet, and the clamping handle is in the retracted state. When the vertical handle portion of the clamping handle is pressed, it pushes open the tongue and exits the vertical handle receiving cavity from the vertical handle inlet and outlet, and the clamping handle is in the prying state.

[0013] The invention of this solution is based on the fact that it fully utilizes the rotation function of the hinge, allowing the rotated vertical handle to smoothly pass through the vertical handle inlet and outlet and be engaged in the vertical handle receiving cavity. Furthermore, it allows the clamping force of the clamping device to be adjusted by adjusting the width of the adjusting tongue, thus keeping the clamping force of the clamping device within a reasonable range.

[0014] Beneficial effects: 1. The clamping force of the clamping device can be adjusted by changing the width, so that the clamping handle is properly confined in the vertical handle receiving cavity, effectively maintaining the cuboid shape of the books and documents. 2. It eliminates the need to extend the clamping handle to maintain the cuboid shape of stacked books and documents, reducing production costs.

[0015] Technical Solution 3: As a preferred embodiment of Technical Solution 2, the two frame-shaped cuts constituting the clamping device are symmetrical along a symmetry axis between the two frame-shaped cuts.

[0016] The two frame-shaped cutouts constituting the clamping device are symmetrical along a symmetry axis between the two frame-shaped cutouts. This restricts the size and position of the tongues, optimizes the structure of the vertical handle receiving cavity, and ensures the balance of clamping forces of the two tongues, which is the inventive point of this solution.

[0017] The frame-shaped cutout doesn't have to be rectangular; it can be a right-angled trapezoid. The upper base near the handle hinge is shorter, and the lower base away from the handle hinge is longer. The right-angled legs are close to the axis of symmetry. The vertical handle receiving cavity is smaller at the end near the handle hinge and larger at the end away from the handle hinge. Within the designed clamping thickness of the clips, the handles can always fit snugly against the book or document, effectively maintaining the book's cuboid shape. Beneficial effect: The two tongues bend to create a balanced force, improving the comfort of use.

[0018] Technical Solution 4: As a preferred option of Technical Solution 3, the tongue is chamfered to make the inlet and outlet of the vertical handle narrow in the middle and wide at the top and bottom.

[0019] The wide upper and lower ends of the vertical handle inlet and outlet facilitate the entry and exit of the clamp handle, while the narrow middle section facilitates the locking of the clamp handle, which is the inventive point of this solution.

[0020] Beneficial effects: It facilitates the insertion and removal of the clamp handle from the vertical handle inlet and outlet, increasing the comfort of use.

[0021] Technical Solution 5: As a preferred solution to Technical Solution 2, either one side edge of the clamp is used as one side of the frame-shaped cut, or both side edges of the clamp are used as two sides of the frame-shaped cut.

[0022] The frame-shaped cut rests on both sides of the clamp, and the two side edges of the clamp can be utilized. The frame-shaped cut rests on the opening and closing end of the clamp, and the opening and closing end of the clamp can be utilized. Preferably, the frame-shaped cut rests on the opening and closing end of the clamp.

[0023] This solution utilizes one or two side edges of the clamp, which not only reduces the difficulty of chiseling the frame-shaped cut, but also allows the clamp handle locking device to be as close as possible to the edge of the clamp, making full use of the edge of the clamp, especially the upper edge of the clamp, which can reduce the height of the clamp, thus becoming the inventive point of this solution.

[0024] Beneficial effects: Fully utilizes the function of the clamping part and saves on the cost of clamping material.

[0025] Technical Solution 6: As a preferred embodiment of Technical Solution 1, the clamping part of the clamping handle hinge device and the clamping handle snapping device includes a pair of frame-shaped cuts facing each other but not connected, and also includes a tongue formed by the frame-shaped cuts separating from the clamping part, and a tongue connecting part connecting the tongue and the clamping part. The clamping handle snapping device includes a pair of cylindrical vertical handle receiving cavities with open ends. Each vertical handle receiving cavity has a vertical handle inlet and outlet on the middle side between the two vertical handle receiving cavities, which allows the vertical handle of the clamping handle to deform inward under pressure and enter the vertical handle receiving cavity. The vertical handle receiving cavity and the vertical handle inlet and outlet are formed by the clamping part between the two tongues after the two tongues are bent towards each other.

[0026] Although there is only one pair of frame-shaped cuts, two vertical handle receiving cavities are still formed. Compared with the vertical handle receiving cavity of technical solution 2, this solution needs to accommodate two vertical handles, and their distance is significantly increased. The material suitable for the elastic deformation requirements of the clamping handle snap-fit ​​device often conflicts with the material required for the elastic deformation of the clamping part. By adding a special vertical handle compression link, when the two vertical handles are compressed towards the middle and deformed, the vertical handles enter the vertical handle receiving cavity from the two vertical handle inlets and outlets. The inventive point of this solution is that it relies on the elastic deformation of the vertical handles rather than the elastic deformation of the tongues that constitute the vertical handle receiving cavity.

[0027] Beneficial effect: By utilizing the elastic deformation of the vertical handle instead of the elastic deformation of the tongue that constitutes the vertical handle receiving cavity, the performance of both the clamp and the tongue is taken into account.

[0028] Technical Solution 7: As a preferred embodiment of Technical Solution 1, the clamping part, which is separated from the clamping handle hinge device and the clamping handle snapping device, is further provided with a frame-shaped cut. The frame-shaped cut forms a tongue, a tongue connecting part connected to the clamping part, and two sides of the tongue of the clamping part adjacent to the tongue. The clamping handle hinge device is either formed by bending the tongue towards the tongue connecting part and then forming the tongue connecting part together, or by bending the tongue away from the tongue connecting part and then forming the tongue connecting part together with the two sides of the tongue of the clamping part.

[0029] Alternatively, a pair of frame-shaped cuts can be chiseled in the clamping part, and the clamping handle hinge device is formed by the two tongues bending towards each other and the part between the two tongues connecting the clamping part.

[0030] The frame-shaped cut is either facing away from or towards the bent ridge, and correspondingly, the tongue faces or is away from the bent ridge. Preferably, the frame-shaped cut is facing away from the bent ridge, and the tongue faces the bent ridge.

[0031] A frame-shaped cut is made in the middle of the clamping part, which not only separates the clamping handle snap-fit ​​device from the clamping handle hinge device, but also reduces the processing difficulty. In particular, it respects the weak ductility of manganese steel, which is the inventive point of this solution.

[0032] Beneficial effects: It reduces the processing difficulty of the clamp hinge device and respects the ductility of manganese steel.

[0033] Technical Solution 8: As a preferred embodiment of Technical Solution 1, the axial direction of the matching clamp hinge device is perpendicular to the axial direction of the clamp snap device.

[0034] Corresponding to the left-right distribution of the handle hinge devices parallel to the bent ridge, the handle locking devices are also distributed left-right. The handle hinge devices and handle locking devices are paired; the left-side handle hinge devices and handle locking devices form one set, and the right-side handle hinge devices and handle locking devices form another set. The handle hinge device includes a hinge shaft receiving cavity, and the handle locking device includes a vertical handle receiving cavity. Although the handle hinge devices and handle locking devices are not connected, the axial directions of their respective receiving cavities are perpendicular.

[0035] Beneficial effects: It makes full use of the advantage of separating the clamp hinge device and the clamp snap device, reducing the difficulty of processing the clamping piece.

[0036] Technical Solution 9: A clamp handle, formed by bending steel wire, optionally including a hinge shaft and a vertical handle bent from the hinge shaft, which are matched with the clamp handle hinge device and clamp handle snapping device of the elastic clamp piece described in Technical Solutions 1, 2, 3, 4, 5, 6, 7 or 8.

[0037] The clamp handle is an open frame shape. The hinge shaft near the opening is hinged in the clamp handle hinge device of the elastic clamp piece. The vertical handle that bends from the hinge shaft can be locked in the clamp handle locking device.

[0038] The shape of the clamping device and its relationship with the clamping hinge device determine the shape of the clamp. The clamp of this solution is adapted to the aforementioned elastic clamp, which is the inventive point of this solution.

[0039] Beneficial effects: The matching handle has better compatibility with the elastic clip.

[0040] Technical Solution 10: A clamp includes a clamping piece and two clamping handles hinged to the clamping piece. Optionally, the clamping piece is the elastic clamping piece described in technical solutions 1, 2, 3, 4, 5, 6, 7 or 8, and the clamping handles are the clamping handles described in technical solution 9.

[0041] Beneficial effects: It solves the problem that the existing binder clips have insufficient clamping force, which makes it impossible to maintain the cuboid shape of books and documents, and the problem that the books and documents held cannot be placed upright. Attached Figure Description

Example

[0043] like Figure 1 .

[0044] An elastic clip is formed by bending a sheet along two parallel bending ridges 16. It includes two clips 1 located on both sides and a connecting part 2 located in the middle connecting the two clips 1. The angle between the plane of the clips 1 and the plane of the connecting part 2 is less than 90 degrees. The clip 1 includes a hinge shaft that defines the handle and rotates therein so that the handle includes a handle hinge device 4 in a prying state and a retracted state, and a handle locking device 5 that locks the handle in the retracted state. The handle hinge device 4 of one clip 1 is separated from the handle locking device 5. The handle hinge device 4 is relatively closer to the bending ridge 16, and the handle locking device 5 is relatively closer to the opening end 6 of the clip 1.

[0045] The clamping part 1, which is separated from the clamping handle hinge device 4 and the clamping handle snap-fit ​​device 5, includes a pair of frame-shaped cutouts 11 facing each other but not connected. It also includes a tongue 12 formed by the frame-shaped cutouts 11 separating from the clamping part and a tongue connecting part connecting the tongue 12 and the clamping part 1. The clamping handle snap-fit ​​device 5 includes a cylindrical vertical handle receiving cavity with open ends and a vertical handle inlet and outlet at the top of the vertical handle receiving cavity for the vertical handle to enter the vertical handle receiving cavity after rotating around the rotation axis of the clamping handle. The vertical handle receiving cavity and the vertical handle inlet and outlet are formed by the clamping part 1 between the two tongues 12 after being bent towards each other.

[0046] The two frame-shaped cutouts 11 constituting the clamping device 5 are symmetrical along an axis of symmetry between the two frame-shaped cutouts 11. The tongue 12 is chamfered, making the inlet and outlet of the vertical handle narrow in the middle and wide at the top and bottom.

[0047] The clamping part 1 also has a frame-shaped cut 11, a tongue 12 formed by separating from the clamping part 1 by the frame-shaped cut 11, a tongue connecting part connected to the clamping part 1 by the tongue 12, two sides of the tongue of the clamping part 1 that are adjacent to the tongue 12, a clamping handle hinge device 4, or a tongue 12 bent toward the tongue connecting part, which together with the tongue connecting part constitutes the clamping part.

[0048] The axis of the matching handle hinge device 4 is perpendicular to the axis of the handle snap-fit ​​device 5.

[0049] Note: In this example, the frame-shaped cutouts 11 are all away from the edge of the clamping part 1. Alternatively, one side edge of the clamping part 1 can be used as one side of the frame-shaped cutout 11, or both side edges of the clamping part 1 can be used as two sides of the frame-shaped cutout 11. Since this is easy to understand, it will not be explained separately. The vertical handle receiving cavity, the vertical handle inlet and outlet, and the tongue connection part can be seen from the figure and are easy to understand. If they were shown in the figure, it would make the schematic diagram too complicated, so they are not shown in the figure.

[0050] like Figure 2 An elastic clamping clip is formed by bending a sheet of material along two parallel bending ridges 16. It includes two clamping portions 1 on either side and a connecting portion 2 in the middle connecting the two clamping portions 1. The angle between the plane containing the clamping portion 1 and the plane containing the connecting portion 2 is less than 90 degrees. In this example, the distances from the opening / closing ends 6 of the two clamping portions 1 to the bending ridges 16 are equal, and the angle between the plane containing the clamping portion 1 and the plane containing the connecting portion 2 is 68 degrees. Each clamping portion 1 includes a hinge shaft that defines a clamping handle, which rotates therein to allow the handle to include a clamping handle hinge device 4 in a prying state and a retracted state, and a clamping handle locking device 5 that engages the clamping handle in the retracted state. The clamping handle hinge devices 4 and clamping handle locking devices 5 of the two clamping portions 1 are separated. The clamping handle hinge devices 4 are relatively closer to the bending ridges 16, and the clamping handle locking devices 5 are relatively closer to the opening / closing ends 6 of the clamping portions 1.

[0051] The clamping part 1, which is separated from the clamping handle hinge device 4 and the clamping handle locking device 5, includes a pair of frame-shaped cutouts 11 facing each other but not connected. It also includes a tongue 12 formed by the frame-shaped cutouts 11 separating from the clamping part and a tongue connecting part connecting the tongue 12 and the clamping part 1. The clamping handle locking device 5 includes a pair of cylindrical vertical handle receiving cavities with open ends. Each vertical handle receiving cavity has a vertical handle inlet and outlet on the middle side between the two vertical handle receiving cavities, which allows the vertical handle of the clamping handle to deform inward under pressure and enter the vertical handle receiving cavity. The vertical handle receiving cavity and the vertical handle inlet and outlet are formed by the clamping part 1 between the two tongues 12 after being bent towards each other.

[0052] The clamping part 1 also has a frame-shaped cut 11, a tongue 12 formed by separating from the clamping part 1 by the frame-shaped cut 11, a tongue connecting part connected to the clamping part 1 by the tongue 12, two sides of the tongue of the clamping part 1 that are adjacent to the tongue 12, a clamping handle hinge device 4, or a tongue 12 bent toward the tongue connecting part, which together with the tongue connecting part constitutes the clamping part.

[0053] The axis of the matching handle hinge device 4 is perpendicular to the axis of the handle snap-fit ​​device 5.

[0054] Note: In this example, the frame-shaped cutouts 11 are all away from the edge of the clamping part 1. Alternatively, one side edge of the clamping part 1 can be used as one side of the frame-shaped cutout 11, or both side edges of the clamping part 1 can be used as two sides of the frame-shaped cutout 11. Since this is easy to understand, it will not be explained separately. The vertical handle receiving cavity, the vertical handle inlet and outlet, and the tongue connection part can be seen from the figure and are easy to understand. If they were shown in the figure, it would make the schematic diagram too complicated, so they are not shown in the figure.

[0055] like Figure 3 A clamp handle, formed by bending steel wire, includes a hinge shaft 21 that matches the clamp handle hinge device and clamp handle locking device of the elastic clamping piece described in technical solutions 1, 2, 3, 4, 5, 6, 7 or 8, and a vertical handle 22 bent from the hinge shaft 21. First, two vertical handles 22 are bent out, with their upper ends connected. The lower end of the left vertical handle 21 is bent to the left to form the left hinge shaft 21, and the lower end of the right vertical handle 21 is bent to the right to form the right hinge shaft 21. In this example, the clamp handle is adapted to elastic clamping pieces where the two clamp handle locking devices are located inside the two clamp handle hinge devices. Alternatively, the lower end of the left vertical handle 22 can be bent to the right to form the left hinge shaft 21, and the lower end of the right vertical handle 22 can be bent to the left to form the right hinge shaft 21, with the two clamp handle locking devices located outside the two clamp handle hinge devices. For ease of understanding, this will not be further illustrated.

[0056] like Figure 4-5 A clamp includes a clamping piece 7 and two clamping handles 3 hinged to the clamping piece 7. The clamping piece 7 is the elastic clamping piece described in technical solutions 1, 2, 3, 4, 5, 6, 7 or 8, and the clamping handles 3 are the clamping handles described in technical solution 9.
