Description

TECHNICAL FIELD

[0001] The utility model relates to a printing product technical field, especially a three-dimensional book capable of realizing walking action. BACKGROUND

[0002] Three-dimensional books are usually used in the fields of children education, popular science reading or creative gifts, and are a kind of books with three-dimensional structure. In the manufacturing process of three-dimensional books, folding, cutting, pasting and other techniques are usually used to ingeniously embed movable three-dimensional structures in the plane book pages, so that readers can obtain visual and tactile interactive experience by operating these components during reading.

[0003] At present, the design of walking action of characters in three-dimensional books mostly adopts a simple structure of straight-line dragging back and forth. For example, a common design is to realize straight-line movement by installing characters on a guide rail. Although this structure can realize basic displacement function, the action form is single, and cannot simulate the complex postures of real walking of characters, such as alternating swing of legs and fluctuation of body, thereby reducing the interestingness and attractiveness of three-dimensional books, and failing to fully meet the expectations of readers for the interactivity of three-dimensional books.

[0040] The preferred embodiments of the utility model are described below in conjunction with the drawings, and it should be understood that the preferred embodiments described here are only used to illustrate and explain the utility model, and are not used to limit the utility model.

[0041] Figure 1 A schematic diagram of a pop-up book 100 capable of realizing walking action according to one embodiment of the utility model is shown, which is described in detail below in conjunction with Figure 1 .

[0042] As Figure 1As shown, the pop-up book 100 mainly comprises a book page 110, a profiled structure 120 and a walking traction mechanism 130. The book page 110 can be made of paperboard, plastic board or other materials, and has a front surface and a back surface. The front surface of the book page 110 is provided with a guide structure 111 extending along a first direction, for guiding the profiled structure 120 and the walking traction mechanism 130 to move along the first direction. The profiled structure 120 is arranged on the front surface of the book page 110, and the profiled structure 120 can be designed in the shape of a person or various animals (the embodiment is described by taking a person as an example), but at least comprises a first leg portion 121a and a second leg portion 121b which can move alternately. The walking traction mechanism 130 is slidably connected to the guide structure 111, and comprises a first pull rod portion 131, a second pull rod portion 132 and a linkage portion 133. The first pull rod portion 131 is connected to the first leg portion 121a of the profiled structure 120, and is configured to be manually operated to pull the first leg portion 121a to move along the first direction. The second pull rod portion 132 is connected to the second leg portion 121b of the profiled structure 120, and is configured to be manually operated to pull the second leg portion 121b to move along the first direction. The linkage portion 133 is connected between the first pull rod portion 131 and the second pull rod portion 132, and has a folding mode and an unfolding mode, and is configured to be folded and unfolded along the first direction under the action of the first pull rod portion 131 and the second pull rod portion 132.

[0043] Specifically, as shown in the figure, Figure 1 the linkage portion 133 is in the folding mode in the initial state, at this time, the user can manually pull the second pull rod portion 132 forward to make the second pull rod portion 132 pull the second leg portion 121b to move along the first direction by a distance, in the process, the linkage portion 133 gradually unfolds (which can be partially unfolded or completely unfolded). Then, the user can manually pull the first pull rod portion 131 forward to make the first pull rod portion 131 pull the first leg portion 121a to move along the first direction by a distance, in the process, the linkage portion 133 gradually folds. Those skilled in the art can understand that the first leg portion 121a and the second leg portion 121b can be moved alternately by alternately pulling the first pull rod portion 131 and the second pull rod portion 132, so as to vividly simulate the walking posture of the person. The linkage portion 133 serves to limit the distance of single movement of the first leg portion 121a and the second leg portion 121b, so that the whole walking action is more coordinated and coherent, and the walking action in the pop-up book 100 is more realistic.

It should be noted that the first sliding groove 111a and the second sliding groove 111b both extend in the first direction and have a preset interval in the second direction. By inserting the partial structure of the walking traction mechanism 130 into the first sliding groove 111a and the second sliding groove 111b, the walking traction mechanism 130 can be slidably connected to the book page 110, so that the walking traction mechanism 130 can move on the book page 110 in the first direction and is not easy to fall off the book page 110. Optionally, a first folding line 112 extending in the first direction is arranged in the middle of the book page 110, and by folding the book page 110 along the first folding line 112, the book page 110 can be neatly folded to facilitate the storage of the three-dimensional book 100. Optionally, the first sliding groove 111a and the second sliding groove 111b are arranged on both sides of the first folding line 112, respectively.
