Description

[0002] Pop-up books are printed toys primarily aimed at children. They feature pre-folded structures within the pages; when the book is opened, the pages move these folds to create a three-dimensional shape, enhancing the user experience.

[0003] In pop-up books, the force of flipping the pages is converted into opposing forces on both sides, stretching the pre-folded structure to form a spherical shape. However, existing technologies limit the position of this spherical shape. Due to the tension on both sides, the spherical shape can only be formed on the page surface and cannot detach from the page plane to form a suspended spherical shape, thus limiting further enhancement of the pop-up book's 3D effect. Furthermore, the spherical shape in existing technologies is subjected to a downward pulling force, making it prone to deformation due to interaction with the pages.

[0048] The embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0049] Figure 1 A schematic diagram of a suspended spherical three-dimensional structure 100 according to some embodiments of the present invention is shown. The suspended spherical three-dimensional structure 100 can be applied to pop-up books. See also Figure 1 The suspended spherical three-dimensional structure 100 can switch between a first form and a second form, including a base plate 110, a column 120, a folding structure 130, and multiple traction ropes 140.

[0050] The upright 120 is connected to the base plate 110, and the upright 120 is movable relative to the base plate 110. In some embodiments, the upright 120 is made by folding a blank, such as cardboard. After being folded, the upright 120 is connected to the base plate 110, for example, by gluing, inserting, or snapping. The upright 120 is movable relative to the base plate 110. Specifically, in a first configuration, the upright 120 is fitted to the base plate 110; in a second configuration, the upright 120 protrudes relative to the base plate 110.

[0051] In some embodiments, the height of the protrusion of the column 120 can be determined based on the dimensions of the base plate 110, the dimensions of the folding structure 130, and the strength of the blank of the column 120, or it can be determined based on the effect to be presented in the pop-up book.

[0052] The folded structure 130 is formed by folding a blank, and the folded structure 130. When in the first state, the folded structure 130 is a flat shape, for example... Figure 2 As shown in the diagram. When the suspended spherical three-dimensional structure 100 is in the second configuration, the folded structure 130 is approximately spherical, for example... Figure 3 As shown in the diagram. The blank of the folding structure 130 includes, for example, cardboard. The suspended spherical three-dimensional structure 100 is applied in the pop-up book. When the pop-up book is closed, the suspended spherical three-dimensional structure 100 is in a first state, and the folding structure 130 is folded and accommodated between the pages of the pop-up book. When the pop-up book is opened, the suspended spherical three-dimensional structure 100 switches to a second state, and the folding structure 130 is approximately spherical.

[0053] Because paper blanks such as cardboard are difficult to form stable curved surfaces, and curved blanks are also difficult to fit into the pages of a pop-up book. In some embodiments, in the second form, the folding structure 130 is an approximately spherical polyhedral shape, with its sides composed of multiple mutually inclined planes, making the folding structure 130 present an approximately spherical three-dimensional structure. For ease of description, it will be referred to as spherical below.

[0054] See Figure 1 The folding structure 130 includes a first connecting piece 131, a second connecting piece 132, and a side panel 133. The first connecting piece 131 and the second connecting piece 132 are located at the axial ends of the sphere of the folding structure 130 in the second configuration. The axial ends of the sphere refer to the two ends of the sphere's diameter; in other words, in the second configuration, the first connecting piece 131 and the second connecting piece 132 are positioned opposite each other.

[0055] The side panel 133 is located between the first connecting piece 131 and the second connecting piece 132. In the second configuration, the side panel 133 forms the side of a spherical three-dimensional structure. In some embodiments, the side panel 133 is connected to the first connecting piece 131 and the second connecting piece 132, and in the second configuration, the side panel 133 bulges outward to form the side of a spherical three-dimensional structure.

[0056] Multiple pull ropes 140 connect the folding structure 130 and the base plate 110, as well as the folding structure 130 and the upright 120. The pull ropes 140 may include, for example, cotton thread or nylon thread. A portion of the pull ropes 140 connects to the first connecting piece 131 and the base plate 110, with the first connecting piece 131 being closer to the base plate 110 than the second connecting piece 132. Another portion of the pull ropes 140 connects to the second connecting piece 132 and the upright 120. The folding structure 130, connected to the base plate 110 and the upright 120 by the multiple pull ropes 140, allows the folding structure 130 to be suspended, not in contact with the plane of the base plate 110. This enhances the richness of the three-dimensional structure in the pop-up book and improves the user experience.

[0057] Multiple pull ropes 140 are connected to the first connecting piece 131 and the second connecting piece 132 in the folding structure 130. The tension of the multiple pull ropes 140 on the folding structure 130 is applied to the axial direction of the spherical three-dimensional structure, which helps to improve the structural stability in the second form, reduce the risk of deformation of the folding structure 130 or compression between the side and the base plate 110, and extend the service life.

[0058] In some embodiments, in a first configuration, the first connecting piece 131 and the second connecting piece 132 of the folding structure 130 are brought close together and folded into a flat shape. For example Figure 2 As shown, in the folding structure 130, the first connecting piece 131 and the second connecting piece 132 are close to each other, for example, the first connecting piece 131 and the second connecting piece 132 are close to each other, and the side panel 133 is bent into a flat shape. In the second configuration, the first connecting piece 131 and the second connecting piece 132 are moved away from each other by the pull rope 140, and the side panel 133 bulges outward, as shown. Figure 3 As shown, it forms an approximately spherical three-dimensional structure.

[0059] For example, when the pages of a pop-up book are closed, the suspended spherical structure 100 is in its first state, with the first connecting piece 131 and the second connecting piece 132 close to each other, forming a flat shape that fits against the pages. When the pop-up book is opened, the first connecting piece 131 and the second connecting piece 132 move away from each other, forming a spherical structure, driven by the pull cords 140 on both sides.

[0060] In some embodiments, the sphere has a large circle position, where the large circle refers to a circle whose center coincides with the center of the sphere and whose radius is equal to the radius of the sphere. In this embodiment, the large circle is located at the midpoint between the first connecting piece 131 and the second connecting piece 132. In the first configuration, the side panel 133 is folded at the large circle position of the sphere. In the first configuration, after the first connecting piece 131 and the second connecting piece 132 are attached, the folded structure 130 has a double-layered flat shape, which helps to reduce the space occupied by the folded structure 130 in the first configuration.

[0061] Figure 4 A schematic diagram of the blank unfolding of the folding structure 130 according to some embodiments of the present invention is shown. (Reference) Figure 4 In some embodiments, the side panel 133 includes a first structural piece 1331 and a second structural piece 1332. For ease of understanding, Figure 4 The preference for blanks in the process is marked according to the corresponding structure number in folded structure 130.

[0062] The first structural piece 1331 and the first connecting piece 131 are integrally formed or belong to the same blank. The second structural piece 1332 and the second connecting piece 132 are integrally formed or belong to the same blank. In some embodiments, the first connecting piece 131, the second connecting piece 132, the first structural piece 1331, and the second structural piece 1332 can be formed by cutting from the same blank, which helps to simplify the processing steps and reduce processing costs.

[0063] In the Figure 4 After the blank shown is folded to form the folded structure 130, the first structural piece 1331 and the second structural piece 1332 are connected to each other, together forming the spherical side surface of the folded structure 130 in the second configuration. In some embodiments, the first structural piece 1331 and the second structural piece 1332 can be glued, snapped together, or connected using other connectors.

[0064] Preferred, such as Figure 4 As shown, in some embodiments of this utility model, the first structural piece 1331 includes a plurality of first sub-pieces 1333, and the second structural piece 1332 includes a plurality of second sub-pieces 1334. The first sub-pieces 1333 extend from the first connecting piece 131 to the second connecting piece 132, and the second sub-pieces 1334 extend from the second connecting piece 132 to the first connecting piece 131. In some embodiments, the first structural piece 1331 extends to and connects with the second connecting piece 132. The second sub-pieces 1334 extend to and connect with the first connecting piece 131, which helps to increase the joint area and reduce the risk of tensile damage.

[0065] In this embodiment, a plurality of first sub-pieces 1333 extend, for example, along the meridians of the spherical three-dimensional structure toward the second connecting piece 132. A plurality of second sub-pieces 133 extend, for example, along the meridians of the spherical three-dimensional structure toward the first connecting piece 131. According to a preferred embodiment of the present invention, a plurality of first sub-pieces 1333 in the first structural piece 1331 are uniformly arranged circumferentially around the first structural piece 131. A plurality of second sub-pieces 1334 in the second structural piece 1332 are uniformly arranged circumferentially around the second structural piece 132. Further, as... Figure 4 As shown, the number of first sub-pieces 1333 in the first structural piece 1331 is equal to the number of second sub-pieces 1334 in the second structural piece 1332, both being six, and they are connected in an alternating manner. Preferably, the blank shapes of the first structural piece 1331 and the second structural piece 1332 can be approximately the same, which helps to reduce processing difficulty and processing cost.

[0066] In some embodiments, both the first sub-piece 1333 and the second sub-piece 1334 include a plurality of trapezoidal pieces 1335. The plurality of trapezoidal pieces 1335 are connected sequentially in the extending direction of the first sub-piece 1333 (or the second sub-piece 1334), and the size of the trapezoidal pieces 1335 gradually increases in the extending direction of the first sub-piece 1333 (or the second sub-piece 1334), and the size of the trapezoidal pieces 1335 gradually decreases after crossing the centerline of the first sub-piece 1333 or the second sub-piece 1334.

[0067] Preferably, the trapezoidal piece 1335 is an isosceles trapezoid, and the bases of adjacent trapezoidal pieces 1335 are rotatably connected to each other, for example, by machining indentation lines at adjacent positions of two trapezoidal pieces 1335 on the blank. The shape of the waist of the trapezoidal piece 1335 can be similar to the meridian shape of a sphere. For example, in the second configuration, the shape of a first sub-piece 1333 (or a second sub-piece 1334) is approximately a spherical diagonal, and the waists of multiple adjacent trapezoidal pieces 1335 form the sides of the spherical diagonal. Simplifying the sides of the spherical diagonal into line segments helps to reduce processing difficulty and minimizes interference between the trapezoidal pieces 1335.

[0068] As shown in Figure 4, in some embodiments, both the first sub-piece 1333 and the second sub-piece 1334 further include multiple connecting pieces 1336. The multiple connecting pieces 1336 are located on one or both sides of the trapezoidal piece 1335. The connecting pieces 1336 are rotatable relative to the trapezoidal piece 1335. The connecting pieces 1336 in the first sub-piece 1333 are fixedly connected to either the trapezoidal piece 1335 or the connecting pieces 1336 in the second sub-piece 1334. Further, the connecting pieces 1336 in the second sub-piece 1334 are fixedly connected to either the trapezoidal piece 1335 or the connecting pieces 1336 in the first sub-piece 1333. For example, the connecting pieces 1336 are glued and fixed to the trapezoidal piece 1335 or another connecting piece 1336.

[0069] Preferably, each trapezoidal piece 1335 has at least one connecting piece 1336, and multiple connecting pieces 1336 are fixedly connected, or multiple connecting pieces 1336 are fixedly connected to multiple trapezoidal pieces 1335. This is beneficial to improve the bonding strength between the first structural piece 1331 and the second structural piece 1332, improve the structural stability of the folding structure 130, and reduce the risk of structural damage to the folding structure 130 caused by the tension of the pull rope 140.

[0070] like Figure 4 As shown, according to a preferred embodiment of the present invention, the folding structure 130 further includes two first reinforcing plates 134. The two first reinforcing plates 134 are respectively fixedly connected to the first connecting plate 131 and the second connecting plate 132. The pull rope 140 passes through the two first reinforcing plates 134 and extends into the interior of the folding structure 130, or the pull rope 140 is fixedly connected to the two first reinforcing plates 134.

[0071] The first reinforcing piece 134 can improve the structural strength of the first connecting piece 131 and the second connecting piece 132. For example, in some embodiments, the first connecting piece 131 and the second connecting piece 132 are made of cardboard, which has limited structural strength and is prone to damage when subjected to repeated tension applied by the pull rope 140, causing the pull rope 140 to detach from the first connecting piece 131 or the second connecting piece 132. In this embodiment, the first reinforcing piece 134 is directly subjected to the tension of the pull rope 140 and distributed to the first connecting piece 131 and the second connecting piece 132, which is beneficial to improving the structural strength of the folding structure 130. Specifically, in some embodiments, the first reinforcing piece 134 is, for example, a plastic sheet, a rubber sheet, or a resin sheet.

[0072] According to a preferred embodiment of the present invention, the end of the pull rope 140 connected to the first connecting piece 131 or the second connecting piece 132 includes two or more connection points to restrict the rotation of the folding structure 130. The tension force exerted by the pull rope 140 on the folding structure 130 is along the axial direction of the folding structure 130, improving the stress stability of the folding structure 130. To prevent the folding structure 130 from rotating around its axis, in this embodiment, the end of the pull rope 140 connected to the first connecting piece 131 or the second connecting piece 132 includes two or more connection points. When the folding structure 130 rotates around its axis, the pull rope 140 can provide a braking force in the opposite direction.

[0073] In some embodiments, multiple connection points at one end of the pull rope 140 that are connected to the first connecting piece 131 or the second connecting piece 132 are evenly arranged around the axial direction of the sphere to reduce the risk of eccentricity of the tension provided by the pull rope 140, which could affect the structural stability of the folding structure 130.

[0074] Preferably, in some embodiments, such as Figure 1As shown, the first connecting piece 131, the second connecting piece 132, and the first reinforcing piece 134 have two through holes. The pull rope 140 passes through the two through holes in sequence and is then fixedly connected to the base plate 110 or the column 120. This helps to reduce the number of pull ropes 140, simplify the structure of the suspended spherical three-dimensional structure 100, and reduce material costs.

[0075] In some embodiments, such as Figure 5 As shown, the column 120 includes a through hole 121. Among the multiple tension ropes 140, the tension rope 140 connected to the column 120 passes through the through hole 121, extends into the interior of the column 120, and is fixedly connected to the base plate 110. In this embodiment, the tension rope 140 passing through the through hole 121 and being fixedly connected to the base plate 110 can reduce the tensile force on the column 120, which is beneficial to improving structural stability. Specifically, the tension rope 140 can be glued and fixed to the base plate 110.

[0076] See Figure 1 According to a preferred embodiment of the present invention, the column 120 is formed by folding a blank, and the column 120 further includes a second reinforcing piece 122, which may be, for example, a plastic sheet, a rubber sheet, or a resin sheet. The position of the second reinforcing piece 122 corresponds to the position of the through hole 121. For example, a hole is drilled in the second reinforcing piece 122, and the position of the hole corresponds to the position of the through hole 121. Preferably, the second reinforcing piece 122 extends to connect with the base plate 110, which helps to further improve the structural stability. (Reference) Figure 6 After the pull rope 140 passes through the through hole 121, it is fixedly connected to the base plate 110. A large downward pressure will be generated at the position of the through hole 121. The risk of the column 120 breaking open at the position of the through hole 121 can be reduced by using the second reinforcing plate 122.

[0077] See Figure 7 and Figure 1 In a preferred embodiment of this utility model, the column 120 and the base plate 110 are inserted and fixed. The base plate 110 includes a third reinforcing piece 111. The position of the third reinforcing piece 111 corresponds to the position where the pull rope 140 is connected to the base plate 110 and the position where the column 120 is inserted into the base plate 110. This can improve the strength of the insertion and fixing of the column 120 and the base plate 110 as well as the strength of the fixed connection between the pull rope 140 and the base plate 110, and reduce the risk of damage at the insertion position of the column 120 and the base plate 110 during the flipping process.

[0078] According to a preferred embodiment of the present invention, the suspended spherical three-dimensional structure 100 includes multiple folding structures 130. The multiple folding structures 130 are connected between the base plate 110 and the column 120 by multiple pull ropes 140. See also... ​The suspended spherical three-dimensional structure 100 includes two folding structures 130. Preferably, the multiple folding structures 130 are located on both sides of the column 120 to prevent the column 120 from being subjected to excessive tensile force on one side, which would cause the column 120 to tilt to the bottom first against the base plate 110. In some embodiments, the column 120 has a certain structural strength, for example, the column 120 includes a second reinforcing plate 122, and the multiple folding structures 130 can be arranged asymmetrically, which is beneficial to improving the design richness of the suspended spherical three-dimensional structure 100.

[0079] The embodiments of this utility model also include a pop-up book (not shown in the figure), which includes inner pages and a suspended spherical pop-up structure 100 as described in the foregoing embodiments. The base plate 110 of the suspended spherical pop-up structure 100 is fixedly connected to the inner pages or integrally formed. For example, the base plate 110 is glued to the inner pages, or the inner pages include a multi-layered structure, with the base plate 110 located within the multi-layered structure.

[0080] According to a preferred embodiment of this utility model, the inner pages include a center seam, the position of which corresponds to the spine of the pop-up book, and the inner pages can rotate around the center seam. The uprights 120 in the suspended spherical pop-up structure 100 are located at the center seam. When the inner pages are closed around the center seam, the uprights 120 fold and fit snugly against the inner pages, and the suspended spherical pop-up structure 100 is in its first state. When the inner pages are unfolded around the center seam, the uprights 120 protrude relative to the inner pages, i.e., the uprights 120 protrude from the base plate 110, and the suspended spherical pop-up structure 100 switches to its second state. The power for flipping the inner pages can be used by the pull rope 140 to switch the folding structure 130 to an approximately spherical pop-up shape.

[0081] Finally, it should be noted that the above descriptions are merely embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
