Summary of the Invention

Problems to be Solved by the Invention

[0005] Such conventional leather products have the limitation that the materials used are basically limited to leather. As a result, there are significant limitations in terms of design and decorativeness. For example, in general leather products such as baseballs, wallets, and storage cases, with a configuration using only leather materials, the variations in designs and patterns that can be expressed are extremely limited, and it has not been possible to sufficiently meet the diverse preferences and needs of consumers. In addition, the use of leather materials alone also has limitations in the expression of colors and textures, and it can be said that there is room for improvement in realizing richer visual effects and artistic decorations.

[0006] The present invention has been made in view of the above-described circumstances, and its object is to provide a leather product that can achieve richer decorativeness and design while maintaining the basic strength and durability of the leather product by combining a first sheet-like member made of a leather material and a second sheet-like member made of a material different from the leather material.

Means for Solving the Problems

[0007] The above-described object of the present invention is achieved by the following configuration. [1] One or more first sheet-like members made of a leather material, One or more second sheet-like members made of a material different from the first sheet-like member, and The second sheet-like member has its peripheral edge sewn to one or more of the first sheet-like members and connected to the first sheet-like member, and is surrounded by the first sheet-like member over the entire area of the peripheral edge. Leather product. [2] The second sheet-like member is configured to include a cloth material at least on its surface portion, and its surface has a pattern by block printing. The leather product according to [1]. [3] An opening is formed in the central portion of at least one of the first sheet-like members, At least one of the second sheet-like members is sewn to the peripheral edge of the opening, so that the second sheet-like member is surrounded by the first sheet-like member. The leather product according to [1] or [2]. [4] Any one of a baseball, a wallet, or a storage case The leather product according to [1].

[0008] It is preferable to adopt the configuration of [1]. In this case, by using a leather material as the first sheet-like member and a material different from the leather material as the second sheet-like member, it is possible to realize a new design property by combining different materials without impairing the basic characteristics of the leather product. In addition, by adopting a configuration in which the peripheral edge of the second sheet-like member is sewn to the first sheet-like member and the entire periphery of the peripheral edge is surrounded by the first sheet-like member, first, the first sheet-like member made of a leather material constitutes the outer peripheral portion, so that the strength and durability as a leather product can be ensured. Next, since the second sheet-like member is protected by the first sheet-like member over the entire periphery, peeling and damage at the ends of different materials are prevented. As a result, it is possible to achieve both practicality and reliability as a product while overcoming the limitations in design and decorativeness that conventional leather products have. It is preferable to adopt the configuration of [2]. In this case, by configuring the surface part to include a cloth material, a soft and warm texture can be imparted to the leather product. Due to the characteristics of this cloth material, it not only provides a comfortable touch when the user picks it up, but also can give a visually calming and luxurious impression. Also, by contrast with the leather material, the fine weave and surface texture unique to the cloth material give a deep expression to the entire product, enabling a richer texture expression. Furthermore, the pattern by katazome applied to its surface allows for a delicate and vivid expression characteristic of the traditional dyeing technique in Okinawa. By this technique, color overlapping, gradation, and delicate pattern expression over details can be realized, producing a rich color expression and unique texture that cannot be achieved by leather material alone. The combination of these elements further improves the design and decorativeness of the entire product, and can create new values not seen in conventional leather products. It is preferable to adopt the configuration of [3]. In this case, by effectively visualizing the second sheet-like member through the opening of the first sheet-like member, a visual emphasis effect due to the contrast between the leather material and different materials can be produced. Also, since the entire peripheral edge of the second sheet-like member is sewn to the opening peripheral edge of the first sheet-like member, the second sheet-like member, which is a different material, is surely protected by the first sheet-like member, which is a leather material, and peeling and damage at the ends can be more surely prevented. Furthermore, by appropriately designing the shape and size of the opening of the first sheet-like member, the exposed area of the second sheet-like member can be adjusted, and more diverse design expressions can be realized. It is preferable to apply the present invention to any one of a baseball, a wallet, or a storage case as in the configuration of [4].

Advantages of the Invention

[0009] According to the present invention, by combining a first sheet-like member made of a leather material and a second sheet-like member made of a material different from the leather material, while maintaining the basic strength and durability of the leather product, richer decorativeness and design can be realized.

[0019] <First Embodiment> Based on FIGS. 1 and 2, the leather product of the first embodiment according to the present invention will be described. In this embodiment, the baseball 10 will be exemplified and described as the leather product.

[0020] [Regarding the basic configuration] With reference to FIGS. 1 and 2, the basic configuration of the baseball 10 (an example of a "leather product") according to this embodiment will be described. FIG. 1 is a perspective view for explaining an example of the appearance of the baseball 10 of this embodiment. FIG. 2 is an exploded perspective view for explaining an example of the structure of the baseball 10 shown in FIG. 1.

[0021] As shown in FIGS. 1 and 2, the baseball 10 of this embodiment is formed in a spherical shape as a whole, and includes a ball core 13 that serves as the basis of the ball body, an elastic layer (not shown) that covers the outer surface of the ball core 13, and at least two types of first outer layer members 11 (an example of a "first sheet-like member") and second outer layer members 12 (an example of a "second sheet-like member") that cover the elastic layer.

[0022] The ball core 13 is composed of, for example, a central ball portion (not shown) provided from a cork material or a synthetic resin material, and a thread material (not shown) wound around the periphery of the central ball portion. The central ball portion has appropriate elasticity and durability and serves to ensure the basic rebound performance of the baseball 10. The thread material is wound around the central ball at a high density to adjust the weight and shape of the ball and has a function of absorbing the impact during hitting.

[0023] The elastic layer is mainly provided with rubber as a raw material and is formed by a heat vulcanization process using a mold. This layer realizes appropriate elasticity and durability, is manufactured under predetermined temperature and pressure conditions, and ensures the required rebound performance and shape stability of the baseball 10.

[0024] The first outer layer member 11, which is the first sheet-like member, and the second outer layer member 12, which is the second sheet-like member, are arranged on the outer surface of the elastic layer and are each formed as a pair of sheet bodies having the same shape and an 8-shaped (Möbius ring shape). In the present embodiment, the first outer layer member 11 and the second outer layer member 12 are stitched to the outer surface of the elastic layer and are integrally fixed to the ball core 13 via the elastic layer, thereby preventing peeling and damage during use.

[0025] Also, in order to ensure the joining of the elastic layer, the first outer layer member 11, and the second outer layer member 12, a spun yarn is wound around the outer surface of the elastic layer, and an adhesive material such as an adhesive gel is applied thereon and firmly adhered and fixed. By this fixing, sufficient durability against impacts and frictions during normal use is ensured.

[0026] As shown in FIG. 2, in the present embodiment, in the manufacturing process, the first outer layer member 11 and the second outer layer member 12 are arranged opposite to each other in a state of intersecting in a cross shape and are bent and attached in a U shape so as to cover the ball core 13 and the elastic layer. Thereby, the first outer layer member 11 and the second outer layer member 12 are aligned at their peripheries and are sewn and connected (an example of "connection") in this aligned state. That is, the second outer layer member 12 has its periphery sewn to the first outer layer member 11 and is connected to the first outer layer member 11, and is in a state of being surrounded by the outer layer member over the entire area of the periphery.

[0027] Furthermore, in the present embodiment, the first outer layer member 11 is made of a leather material. On the other hand, the second outer layer member 12 has a configuration including a cloth material on its surface portion, and a pattern by block printing is applied to its surface.

[0028] That is, in the present embodiment, the first outer layer member 11 is made of a leather material, has a characteristic texture, and realizes ensuring the durability of the baseball 10.

[0029] On the other hand, the second outer layer member 12 is configured to include a cloth material having a unique texture on its surface portion. This cloth material is formed from a woven fabric mainly made of natural fibers such as cotton, hemp, and silk, and a uniquely highly decorative pattern is applied (dyed) to its surface by katazome. Specifically, by applying a resist paste using a stencil and then dyeing the pattern using a vegetable dye, a delicate and vivid color expression is realized. The decoration by this katazome is finished using traditional techniques, and in combination with the contrast with the leather material and the natural texture of the cloth material, it imparts unique aesthetic value to the baseball 10.

[0030] [Features and Advantages of the Present Embodiment] [1] As described above, according to the baseball 10 (an example of a "leather product") of the present embodiment, it includes one or a plurality of first outer layer members 11 (an example of a "first sheet-like member") made of a leather material, and one or a plurality of second outer layer members 12 (an example of a "second sheet-like member") made of a material different from the first outer layer member 11. The second outer layer member 12 has its periphery sewn to one or a plurality of the first outer layer members 11 and is connected to the first outer layer member 11, and is surrounded by the first outer layer member 11 over the entire area of the periphery.

[0031] Therefore, by using a leather material as the first outer layer member 11 (an example of a "first sheet-like member") and a material different from the leather material as the second outer layer member 12 (an example of a "second sheet-like member"), it is possible to realize a new design property by combining different materials without impairing the basic characteristics of the leather product. In addition, by adopting a configuration in which the periphery of the second outer layer member 12 is sewn to the first outer layer member 11 and the entire area of the periphery is surrounded by the first outer layer member 11, first, the first outer layer member 11, which is a leather material, constitutes the outer peripheral portion, so that the strength and durability as a leather product can be ensured. Next, since the second outer layer member 12 is protected by the first outer layer member 11 over the entire periphery, peeling and damage at the ends of different materials are prevented. Thereby, while overcoming the limitations in design and decorativeness that conventional leather products have, it is possible to achieve both practicality and reliability as a product.

[0032] [2] Further, according to the baseball ball 10 (an example of a "leather product") of the present embodiment, the second outer layer member 12 (an example of a "second sheet-like member") is configured to include a cloth material at least on its surface portion, and its surface has a pattern by block printing.

[0033] Therefore, by being configured to include a cloth material on the surface portion, a soft and warm texture can be imparted to the leather product. Due to the characteristics of this cloth material, it can not only provide a comfortable touch when the user picks it up, but also give a visually calming and luxurious impression. Also, by contrast with the leather material, the fine weave and surface texture peculiar to the cloth material give a deep expression to the whole product, and a richer texture expression can be realized. Furthermore, the pattern by block printing applied to its surface enables a delicate and vivid expression which is a characteristic of the traditional dyeing technique in Okinawa. By this technique, color overlapping, gradation, and delicate pattern expression over the details can be realized, producing a rich color expression and a unique texture that cannot be achieved by the leather material alone. By combining these elements, the design and decorativeness of the whole product can be further improved, and new values that were not seen in conventional leather products can be created.

[0034] <Second Embodiment> Based on FIGS. 3 and 4, the leather product according to the second embodiment of the present invention will be described.

[0035] [Regarding the basic configuration] Based on FIGS. 3 and 4, the leather product according to the present embodiment will be described. In the present embodiment, a wallet 20 will be exemplified and described as the leather product.

[0036] While referring to FIG. 3, an example of the basic configuration of the wallet 20 (an example of a "leather product") according to the present embodiment will be described. FIG. 3 is a perspective view for explaining an example of the appearance of the wallet 20 of the embodiment. For components that are the same as or equivalent to those in the aforementioned first embodiment, the same or equivalent reference numerals may be used in the drawings, and the description thereof may be omitted or simplified.

[0037] As shown in FIG. 3, the wallet 20 of this embodiment is composed of an exterior portion 26 and an interior portion 27. The exterior portion 26 is the portion that is exposed to the outside and forms the outer or surface part. The interior portion 27 is the portion that is hidden from the outside and is partitioned as an area for storing keys and the like inside, and forms the inner or back part.

[0038] The outer layer portion of the wallet 20 is configured to include a first sheet-like member 21 that is disposed occupying many regions of the surface part. The first sheet-like member 21 is made of a leather material, and an opening 24 is formed in the central portion thereof. At the opening 24 of the first sheet-like member 21, the second sheet-like member 22 is sewn at its peripheral edge, so that the second sheet-like member 22 is surrounded by the first sheet-like member 21. The peripheral edge of the second sheet-like member 22 is hidden and disposed so as to be on the back side (inside) of the opening 24 of the first sheet-like member 21 in its thickness direction.

[0039] The surface part of the second sheet-like member 22 is formed of a cloth material, and is patterned by a stencil in the same manner as in the aforementioned first embodiment. And the entire peripheral edge of the second sheet-like member 22 is sewn to the peripheral edge of the opening 24 of the first sheet-like member 21. By sewing at the peripheral edge of the opening 24, the second sheet-like member 22 is surely surrounded by the first sheet-like member 21, and as a result, a structurally stable structure is realized as the wallet 20.

[0040] [Regarding the Features and Advantages of this Embodiment] [3] As described above, according to the wallet 20 (an example of a "leather product") of the present embodiment, an opening 24 is formed in the central portion of at least one of the first sheet-like members 21, and at least one of the second sheet-like members 22 is sewn to the peripheral edge of the opening 24, so that the second sheet-like member 22 is surrounded by the first sheet-like member 21.

[0041] Therefore, by effectively visualizing the second sheet-like member 22 through the portion of the opening 24 of the first sheet-like member 21, a visual emphasis effect due to the contrast between the leather material and the different material can be produced. Further, since the entire peripheral edge of the second sheet-like member 22 is sewn to the peripheral edge of the opening 24 of the first sheet-like member 21, the second sheet-like member 22, which is a different material, is reliably protected by the first sheet-like member 21, which is a leather material, and peeling and damage at the end portion can be more reliably prevented. Furthermore, by appropriately designing the shape and size of the portion of the opening 24 of the first sheet-like member 21, the exposed area of the second sheet-like member 22 can be adjusted, and more diverse design expressions can be realized.

[0042] [Regarding the modification according to the second embodiment] One or more modifications according to the present embodiment will be described. Note that for components that are the same as or equivalent to those of the aforementioned first embodiment or second embodiment, the same or equivalent reference numerals may be given in the drawings, and the description thereof may be omitted or simplified. Also, regarding the technical content described in the claims of the utility model registration, the subject matter is not limited to any one or more of these modifications.

[0043] (Regarding the first modification according to the present embodiment) With reference to FIG. 4, an example of the basic configuration of a key holder 30 (an example of a "leather product") according to one modification of the present embodiment will be described. FIG. 4 is a perspective view showing a first modification according to the present embodiment.

[0044] As shown in FIG. 4, in this modification, the leather product is a key holder 30 (an example of a "storage case"). This key holder 30 has a practical function for storing keys and small items, while achieving the same design as in the second embodiment described above. Also, in this modification, the opening 34 is formed in a cloud shape. Other configurations are the same as those in the second embodiment described above.

[0045] <Finally> Although the description of one or more specific embodiments has been completed above, the aspects of the present invention are not limited to these embodiments, and can be appropriately modified, improved, etc.

[0046] That is, it is obvious that those skilled in the art can conceive of various change examples, correction examples, substitution examples, addition examples, deletion examples, equivalent examples within the scope described in the claims for utility model registration, and it is naturally understood that those also belong to the technical scope of the present disclosure. Also, within the scope not departing from the gist of the invention, the components in the above-described embodiments may be arbitrarily combined.

[0047] For example, in the above-described embodiments, a baseball (10), a wallet (20), and a storage case (for example, a key holder (30)) are shown as examples of leather products, but the application of the present invention is not limited to these. The present invention can also be applied to other leather products such as belts, notebook covers, bags, and shoes.
