Description

Technical Field

[0001] This utility model relates to the field of book technology, and in particular to a zippered leather case and a book. Background Technology

[0002] In today's bookbinding industry, with the increasing richness of knowledge content and the development of paper technology, many books, especially religious classics, academic works, professional textbooks, and some high-quality picture albums, often need to carry a large amount of information. This results in an increase in the amount of paper used, significantly increasing the overall thickness and weight. These heavy books face a common problem during use: the edges are easily damaged by frequent flipping, squeezing, and bumping, which not only affects the book's lifespan but also reduces the reader's experience.

[0003] To address this issue, some book designers have experimented with using zippers to lock the book's cover, protecting the book's edges from damage through the zipper's closing mechanism. For example: Figure 1a , Figure 1b and Figure 1c The diagrams illustrate a book 100 with a zipper structure according to related technologies, wherein both ends of the zipper 110 terminate before the spine. When the zipper 110 is unzipped, the zipper head 111 often gets stuck before the spine of the cover, preventing the cover from laying flat in one go. Users must press down hard on the book 100 to barely lay it flat. This not only inconveniences readers but also limits the widespread application of zipper structures in bookbinding.

[0004] Therefore, how to design a book that can effectively protect the book edge and is easy to lay flat is a technical problem that urgently needs to be solved in the current bookbinding field.

[0005] The content of the background section is merely the technology known to the inventor and does not necessarily represent the prior art in this field. Utility Model Content

[0039] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0040] Figure 2 A schematic diagram of a book 200 according to one embodiment of the present invention is shown. Figure 3a , Figure 3b and Figure 3c A schematic diagram illustrating the unfolding process of a book 200 according to an embodiment of the present invention is shown below. Figure 2 , Figures 3a to 3c Provide a detailed description.

[0041] like Figure 2 , Figures 3a to 3c As shown, the book 200 includes a zippered cover 210 and a book block 220. The book block 220 is located inside the zippered cover 210, and its spine is connected to the middle of the zippered cover 210. The book block 220 and the zippered cover 210 can be fixedly connected by means of adhesive, sewing, etc., to ensure a firm connection between the book block 220 and the zippered cover 210. In other embodiments, the book block 220 and the zippered cover 210 can also be detachably connected by means of magnetic snaps, snaps, etc., to facilitate readers to replace the zippered cover or perform other personalized operations as needed.

[0042] like Figure 2 , Figures 3a to 3c As shown, the zippered cover 210 mainly includes a cover 230 and a zipper 240. The cover 230 mainly includes a spine 231, a cover 232, and a back cover 233. The spine 231 has an upper side 231a, a lower side 231b, a front side 231c, and a back side 231d. The cover 232 is connected to the front side 231c of the spine 231, and the back cover 233 is connected to the back side 231d of the spine 231. Both the cover 232 and the back cover 233 can be flexibly flipped around the spine 231 for convenient reader use. A first notch 234 is provided on the upper side 231a of the spine 231, and a second notch 235 is provided on the lower side 231b of the spine 231.

[0043] The zipper 240 includes a first zipper tape 241, a second zipper tape 242, and a zipper pull 243. The first zipper tape 241 is disposed along the edge of the cover portion 232, and its two ends extend to a first notch 234 and a second notch 235, respectively. The second zipper tape 242 is disposed along the edge of the bottom cover 233, and its two ends extend to the first notch 234 and the second notch 235, respectively. The zipper pull 243 connects the first zipper tape 241 and the second zipper tape 242. Pulling the zipper pull 243 in different directions can open or close the first zipper tape 241 and the second zipper tape 242. For example, in... Figure 2 In the illustrated embodiment, as the zipper head 243 is pulled from the first notch 234 to the second notch 235, the first zipper strap 241 and the second zipper strap 242 are gradually pulled apart, and the cover portion 232 and the bottom cover 233 of the cover 230 separate accordingly. When the zipper head 243 is pulled into the second notch 235, the cover 230 can be completely flattened without additional operation or external force pressing. Correspondingly, as the zipper head 243 is pulled from the second notch 235 to the first notch 234, the first zipper strap 241 and the second zipper strap 242 are gradually pulled together. When the zipper head 243 is pulled into the second notch 235, the zipper cover 210 is locked, thereby protecting the book opening from external damage.

[0044] According to one embodiment of the present invention, such as Figure 2As shown, the first notch 234 and the second notch 235 can be trapezoidal notches. Such notches can accommodate the zipper pull 243 and facilitate the connection between the spine 231 and the first zipper tape 241 and the second zipper tape 242. Those skilled in the art will readily understand that the first notch 234 and the second notch 235 can also be other shapes. For example, the first notch 234 and the second notch 235 can also be rectangular notches, arc-shaped notches, V-shaped notches, U-shaped notches, etc. It should be noted that the shapes of the first notch 234 and the second notch 235 can be the same or different, and this utility model is not limited thereto.

[0045] According to one embodiment of the present invention, such as Figure 2 As shown, a crease 236 is provided in the middle of the spine 231. One end of the crease 236 extends to the first notch 234, and the other end extends to the second notch 235. By providing the crease 236 on the spine 231, the zipper cover 100 can be naturally folded and unfolded along the crease 236, which makes it easier for the zipper cover 100 to flatten and further improves the user experience.

[0046] According to one embodiment of the present invention, such as Figure 2 , Figures 3a to 3c As shown, the first zipper tape 241 includes a first base fabric 241a and a plurality of first zipper teeth 241b. The first base fabric 241a may be a long strip of fabric. The plurality of first zipper teeth 241b are evenly arranged along the extending direction of the first base fabric 241a and connected to one edge of the first base fabric 241a; the other edge of the first base fabric 241a is fixedly connected to the edge of the spine portion 231 and the cover portion 232. Preferably, the first base fabric 241a is sewn to the edge of the spine portion 231 and the cover portion 232. Correspondingly, the second zipper tape 242 includes a second base fabric 242a and a plurality of second zipper teeth 242b. The second base fabric 242a may be a long strip of fabric. The plurality of second zipper teeth 242b are evenly arranged along the extending direction of the second base fabric 242a and connected to one edge of the second base fabric 242a; the other edge of the second base fabric 242a is fixedly connected to the edge of the spine portion 231 and the bottom cover 233. Preferably, the second base fabric 242a is sewn onto the edges of the spine 231 and the bottom cover 233.

[0047] According to one embodiment of the present invention, such as Figure 2As shown, the first base fabric 241a and the second base fabric 242a can be made of elastic fabric to allow the zipper 240 to adapt to changes in the thickness of the book 200 during long-term use, ensuring that the zipper 240 can be easily opened and closed. Specifically, thickness changes often occur due to factors such as paper deformation, humidity changes, loosening of the binding structure, and accumulation of dust and dirt. This design effectively addresses such thickness changes, ensuring that the zipper 240 can still be easily opened and closed even when the book 200 becomes thicker, thus guaranteeing the normal functioning of the zipper 240. Those skilled in the art will readily understand that in other embodiments, one of the first base fabric 241a and the second base fabric 242a may be made of elastic fabric, while the other may be made of non-elastic fabric (or a fabric with weak elasticity).

[0048] According to one embodiment of the present invention, such as Figure 2 As shown, the zipper 240 may further include an upper stop 244 and a lower stop 245. The upper stop 244 is located at the first notch 234 and is fixedly connected to the first zipper tape 241 and the second zipper tape 242, respectively. The lower stop 245 is located at the second notch 235 and is fixedly connected to the first zipper tape 241 and the second zipper tape 242, respectively. By providing the upper stop 244 and the lower stop 245, the range of motion of the zipper head 243 can be limited (the zipper head 243 can only move between the upper stop 244 and the lower stop 245), effectively preventing the zipper head 243 from colliding with the spine 231 of the cover 230, thereby avoiding scratches to the spine 231 by the zipper head 243.

[0049] According to a preferred embodiment of the present invention, two zipper heads 243 can be provided between the first zipper tape 241 and the second zipper tape 242. The two zipper heads 243 have opposite opening and closing directions. Specifically, one zipper head 243 is opened from the first notch 234 to the second notch 235 and closed from the second notch 235 to the first notch 234; correspondingly, the other zipper head 243 is opened from the second notch 235 to the first notch 234 and closed from the first notch 234 to the second notch 235.

[0050] According to one embodiment of the present invention, such as Figure 2 As shown, zipper 240 can be a waterproof zipper 240. With this feature, the zipper cover 210 can have a certain degree of water resistance, thereby effectively preventing the book block 220 from getting wet from a small amount of water splash, providing additional protection for the book 200.

[0051] Compared with related technologies, the embodiments of this utility model provide a zippered book cover and a book. By providing a first notch and a second notch on the upper and lower sides of the spine of the book cover, respectively, and extending the two ends of the first zipper strap and the two ends of the second zipper strap to the first and second notches, respectively, the zipper pull can be pulled to the positions of the first and second notches. This design not only effectively solves the problem in related technologies where the book cover cannot be completely flattened in one go due to the zipper pull getting stuck, significantly improving the user experience, but also allows the book to be opened more easily and completely flattened without additional operation or external pressure. Simultaneously, the zipper's closing function can tightly lock the book cover, protecting the book edge from external damage and improving the book's durability and lifespan.

[0052] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is 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.
