Description

Technical Field

[0001] This invention belongs to the technical field of reading aids, and particularly relates to a standing reading clip with a clip. Background Technology

[0002] Existing invention patents such as the book clip (CN200510067516.9), the standing book clip (CN200610081698.X), the sliding sleeve of the standing book clip (CN200910179317.5), the sliding sleeve with two wings (CN201420291608.X), and a standing book clip (CN202311632579.9) all disclose a reading aid or its accessories. These devices use clips at both ends of a lever to hold and position the pages, preventing them from flipping around. They also support the book upwards to provide an optimal reading angle. These are compact reading aids that free the reader's hands by providing an optimal viewing angle and are easy to carry. However, because only the wire clips at both ends of the lever act as the main clamps to hold the opened pages... The book is positioned on both sides to hold the pages, which effectively prevents pages from flipping randomly. However, there is no dedicated clamping structure for easy page turning during reading, meaning there are no auxiliary clamps. This forces users to frequently open the two side clamps (the main clamps) to turn pages each time, which is cumbersome, laborious, and seriously affects the usability and user experience. In addition, due to the design requirements for portability, the length of the thickest section of the pull rod cannot be too long, which limits the length of the clamps. In actual use, users need the clamps to have long clamp arms to hold thicker books. If the length of the clamps at both ends is long enough due to the aforementioned limitation of the pull rod length, the clamps will inevitably encroach on the space between the left and right clamps. In other words, the gap between the handles on the left and right clamps for easy operation is too small to accommodate fingers, thus causing operational obstacles and seriously affecting usability. Summary of the Invention

[0003] This invention provides a standing reading clip with an auxiliary clip, which can solve the above-mentioned technical problems.

[0004] To achieve the above objectives, the technical solution adopted by this invention is as follows: It comprises a set of two identical tie rods arranged side by side, formed by connecting multiple sections of tubular rods of gradually varying thickness. Each end of the tie rod is fitted with a clamp, and a sliding sleeve is also connected to the tie rod. The sliding sleeve is movably connected to the support leg assembly via an inclined stop at its center. The clamp is a handleless wire clamp comprising a clamping arm, a clamping leg, and a clamping ring. A horizontal isosceles trapezoidal clamping plate is connected to each clamping arm by means of a clamping wire engaging with the tube clamp. The clamping tube is positioned below the waist of the clamping plate. At the wide end of the clamping plate, there is a hand plate that is upturned. The left end face of the clamping tube is not aligned with the left end face of the clamping plate. Instead, the left end face of the clamping plate extends to the left and widens to form an upper clamping body. This widened part on the clamping plate, i.e. the upper clamping body, forms a sharp angle structure with the clamping arm below it, thus becoming an auxiliary clamp.

[0005] Furthermore: the clamp arm of the clamp is in the shape of an arc with the left side lower than the right side and the right side higher than the left side, and the clamp legs of the clamp are downwardly tapered and rolled into a clamping loop at the lower end.

[0006] Furthermore, the outer ends of the clamping rings on the clamp are all inclined downwards, that is, the axes of the two clamping rings on a clamp are not on the same straight line, but the outer ends are inclined downwards at a certain angle.

[0007] Furthermore: the card tubes on the card plate are arranged in two sections, left and right, below the waist of the card plate, with a gap between the two sections.

[0008] By using the above technical solution, the present invention has the following beneficial effects compared with the prior art: 1. Due to the design of the auxiliary clip structure, when reading, the reserved page can be easily placed downwards against the clip arm and guided along the left-low-right-high direction of the clip arm to be easily inserted into the pointed corner clip structure of the right auxiliary clip. When turning the page, it can easily detach from the pointed corner clip of the right auxiliary clip and be inserted into the pointed corner clip of the left auxiliary clip. Moreover, the page turning operation can be completed with one hand without the need for both hands, bringing convenience to easy reading.

[0009] 2. Since the handleless wire clip does not have a handle at the clamping point (the clamping point refers to the left end of the clip when viewed from the front), during operation, the lever can be stretched to the left and right and the clamping point can be opened by using the locking plates and hand levers embedded in the clamping arms to clamp the pages. The gap between the left and right hand levers is increased, so the clamping arms can be lengthened without increasing the length of the lever tube, providing sufficient conditions for clamping thicker books, thus increasing the applicability of this design.

[0010] 3. Because the outer ends of the two clamping rings on each clamp are designed to slope downwards, when the clamps are installed at the left and right ends of the pull rod assembly, a straight rod-shaped shaft passes through and connects the two clamping rings at each end. Under the action of this shaft, the two clamping rings are forced to change from an inclined distribution to a more straight distribution. This forces the two upward clamping legs above the clamping rings and directly connected to them to press tightly together and generate an elastic compressive force towards each other. That is, under the above conditions, the two clamping legs on the clamp, together with the clamping arms, will generate an elastic compressive force or pre-tightening force towards each other. This pre-tightening force will make them difficult to separate, even under external force. Even if forced to separate under intervention, the clamping plate will return to its original position or close together after the external force is removed. As mentioned above, when the clamping plate on the clamping arm is set near the middle of the clamping arm rather than too far to the left or right, when pulling the levers to both ends, the thumbs on each side need to hold the handplate and pull the levers to both sides. In this way, the clamping plate will first slide along the clamping arm to each end in the direction of the thumb's force until it is blocked by the clamping leg at the end. Then, the force of the thumb is transmitted to both ends of the lever through the handplate, clamping plate, clamping leg, etc., to pull the levers apart. When the external force is removed, the clamping plate will slide back to its original position under the pre-tightening force of the clamping arm. This effect can facilitate the clamping of the reserved page and also reduce the overall height for easy storage. Attached Figure Description

[0018] The following examples, with reference to the attached diagrams, illustrate the specific implementation of this design.

[0019] like Figure 1 , Figure 2 , Figure 3As shown, this design includes a standing reading clip with an auxiliary clamp, comprising two parallel pull rods (assemblies) 1, each consisting of multiple sections of tubular rods of varying thickness connected together. Each pull rod has a clip (handleless wire clip) 3 connected to both ends. A sliding sleeve 2 is also connected to the pull rod, and the sliding sleeve is movably connected to the support leg assembly via an inclined stop at its center. The clip 3 is a handleless wire clip comprising a clamping arm 6, clamping legs 7, and a clamping ring 8. Figure 4 , Figure 5 , Figure 6 As shown, the clamp arm 6 of the clip is an arc shape with the left side lower than the right side and a convex shape. This allows the clamping jaw (left end) to hold thicker pages. If the clamp arm were straight, it would greatly reduce the thickness of the pages it can hold and would also be less aesthetically pleasing. The clamp legs 7 are downwardly tapered (tilted to the left). This inward-tapering design provides a point of force for application during operation. The lower ends of the clamp legs are rolled into clamping rings 8 to accumulate elastic clamping force. At the same time, the outer ends of the clamping rings on each side are inclined downwards, meaning that the axes of the two clamping rings on a single clip are not on the same straight line, but their outer ends are both inclined downwards at a certain angle. Figure 5 As shown; a horizontal isosceles trapezoidal clamping plate 4 is connected to the clamping arm 6 of the clamp via clamping wires that are embedded into clamping tubes 9. The clamping tubes 9 on the clamping plate 4 are all located on the isosceles side below the plate surface. The trapezoidal shape of the clamping plate (i.e., the angle between its two sides) matches the angle between the two clamping wires on the clamping arm 3, which are distributed at a certain angle. This allows the two to be assembled together harmoniously via the clamping tubes. For easier use, the clamping plate is best installed in the middle of the clamping arm rather than at the left or right end. This can be achieved by setting the width and length dimensions of the clamping plate. Figure 3 As shown; simultaneously, the left end face of the clamping tube 9 is not aligned with the left end face of the clamping plate 4, but moves to the right by a certain distance. Alternatively, it can be understood that the clamping plate extends and widens to the left in the direction of the left end face of the clamping tube, becoming the upper clamping body 10. This leftward extension, i.e., the upper clamping body, is designed for the specifications of injection molding, and also to make it part of the auxiliary clamp (i.e., the upper clamping body of the auxiliary clamp). This upper clamping body 10 on the clamping plate 4 forms a clamping structure with a sharp angle 11 between it and the clamping arm 6 below (i.e., the lower clamping body of the auxiliary clamp), thus becoming the auxiliary clamp. Figure 8 , Figure 9As shown, the clip structure of the auxiliary clip with its sharp corner 11 is very small. Considering that the thickness of each page is no more than 0.1mm and the reserved pages are generally no more than 0.5mm thick, to achieve the clipping effect, this sharp corner is generally set to an acute angle of no more than 15 degrees, or even 6-10 degrees is optimal. This way of setting the auxiliary clip creates a cleverly fitted sharp corner in terms of physical structure. In the specific practical use of this product, the reader uses the clips 3 at both ends of the pull rod, i.e., the main clips, to clamp the main body of the book 12 that they want to open. After the pages are finished, simply spread the reserved pages 13 gently towards the right side of the aforementioned pointed-corner clamp. The pointed-corner structure of the right clamp will easily capture and hold the right side of the reserved pages. When you need to turn the page, the reserved pages can be easily pulled away from the right pointed-corner clamp. The turned pages can then be easily clamped back into the pointed-corner clamp on the left side. In other words, this pointed-corner clamp structure allows you to hold or release the pages with just one hand, without relying on the operation of both hands. Figure 10 As shown; a curved handplate 5 is also connected to the wide end (left end) of the clamping plate 4. The handplate is mainly designed to facilitate the thumb pulling open the lever and opening the clamp. Because the clamp 3 in this design is a handleless wire clamp, it does not have the conventional handle that is directly gripped by the wire for operation. The handplate in this design provides a larger operating space while also serving the function of the original handle. Figure 1 , Figure 2 As shown; the clamping tube 9 below the aforementioned clamping plate 4 is not completely closed around its circumference but has a notch to facilitate the insertion of the clamping arm wire into the clamping tube through the reserved notch. Ideally, the clamping tube should be distributed in two sections, left and right, with a gap between the two sections. This is mainly to facilitate the insertion of the wire into the clamping arm. The clamping plate with the gap between the clamping tubes allows for easier plastic deformation during the assembly operation of inserting the clamping arm wire to adapt to the upward curvature of the clamping arm wire, resulting in faster and more efficient assembly. Figure 7 , Figure 8 , Figure 9 As shown.

[0020] The aforementioned clip 3 is a handleless wire clip. It does not have a handle at the clamping opening (i.e., the left end of the clip when viewed from the front). During operation, the lever can be stretched to the left and right and the clamping opening can be opened by using the locking plate and hand plate embedded in the clamping arm to clamp the pages. The gap between the left and right hand plates is increased, so the clamping arm can be lengthened without increasing the length of the lever tube, providing sufficient conditions for clamping thicker books, thus increasing the applicability of this design.

[0021] The outer ends of the two clamping rings on each of the aforementioned clamps are designed to slope downwards. When the clamps are positioned at the left and right ends of the pull rod assembly, a straight rod-shaped shaft passes through and connects the two clamping rings at each end. Under the action of this shaft, the two clamping rings are forced to change from an inclined distribution to a more straight distribution. This forces the two upward-facing clamping legs, which are directly connected to the clamping rings, to press tightly together and generate an elastic compressive force towards each other. In this situation, the two clamping legs and the clamping arms will generate an elastic compressive force, or pre-tightening force, towards each other. This pre-tightening force makes them difficult to separate. If forced apart by external force, they will return to their pressed position or original position after the external force is removed. As mentioned above, the clamping plate on the clamping arm is positioned at the clamping arm... When the lever is positioned near the middle section rather than the left or right end, pulling the lever towards both ends requires applying external force with the thumbs on each side to hold the handplate and pull the lever apart. The clamping plate will first slide along the guide rail formed by the clamping arms in the direction of the thumb's force until it is blocked by the clamping legs at the end (because this method of connecting the steel wire and the clamping tube is difficult to fix still, it will shift under sufficient external force). At this point, the clamping arms and clamping legs will change from their original position of being close or tight to being far away. Then, the force applied by the thumb is transmitted through the handplate, clamping plate, and clamping legs to both ends of the lever to pull it apart. When the external force is removed, the clamping plate will automatically slide back to its original position, i.e., the middle section of the clamping arms, under the pre-tightening force of the clamping arms and clamping legs (the clamping arms and clamping legs also return to their original close position). This effect facilitates the clamping of the reserved page and also reduces the overall height. Figure 1 , Figure 2 As shown, the overall height can be reduced by at least 10% compared to the other two, which provides convenience for storage and other purposes, and has a significant positive effect with multiple benefits; however, if the outer end of the clamping ring is not set to be inclined downwards but is the usual straight shape, the clamping legs and clamping arms will not obtain the aforementioned pre-tightening force, and the clamping plate and hand plate will be difficult to actively return to their original positions after being moved away from their original positions under the action of external force.

[0022] Of course, with the aforementioned upper clamping body in place, the aforementioned auxiliary clamping angle structure can also be achieved by using a spring plate as the lower clamping body, and the setup methods are varied.

[0023] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
