Description

Technical Field

[0001] The present invention relates to a leather model kit (leather three-dimensional modeling kit) made of leather that includes both toy play elements of a plastic model and leathercraft creation elements, and a method for manufacturing the same.

Background Art

[0002] Conventionally, as this type of leather model kit, a leather sheet for forming a three-dimensional animal model shown in Patent Document 1 has been considered. This leather sheet for forming a three-dimensional animal model makes the leather sheet temporarily flexible by containing moisture in the leather sheet for forming a three-dimensional animal cut and cut into the shape of the animal outline, rounding, stretching, bending to form three-dimensionally, and shaping it into the outer shape of a predetermined animal.

[0003] However, by making the leather sheet temporarily flexible by containing moisture in the leather sheet that has formed the three-dimensional animal model, rounding, stretching, bending to form three-dimensionally, and shaping it into the outer shape of a predetermined animal, due to the characteristics of the leather material, although the leather can temporarily obtain the property of being easy to form by containing moisture, it is difficult in terms of the nature of the leather to continuously maintain the shape of the animal outer shape formed using the leather sheet from which the moisture has escaped and dried. Also, since it is a handicraft that is three-dimensionally assembled by rounding, stretching, and bending a single leather sheet shaped to fit the outer shape of the motif, unlike a model that combines and assembles a plurality of members with different shapes, structurally it is close to papercraft, so it is poor at expressing an appropriate image and posture for each part.

Summary of the Invention

Problems to be Solved by the Invention

[0005] On the one hand, the inventor of the present application is considering providing a novel leather model kit that has never existed before, which combines the toy-play elements of a plastic model and the leather craft creation elements. Specifically, by overcoming the difficulty of reusing plastic models and the high threshold of leather crafts, and by adopting a configuration that includes both of these two elements, the inventor is considering providing a new form of model that combines a leather craft as a starting point with a model toy.

Means for Solving the Problems

[0006] That is, the leather model kit according to the present invention is a leather model kit for assembling a completed body with motifs such as organisms and artifacts. It corresponds to each part of the completed body and has a plurality of model member parts in a developed shape. The model member parts have through holes formed at required locations, and by sewing using needles and threads through these through holes, the completed body is assembled by the plurality of model member parts. This is the characteristic. According to this leather model kit, since a plurality of model member parts with pre-formed through holes can be sewn together to assemble a completed body, it is possible to provide a novel leather model kit that has never existed before and combines the toy-play elements of a conventional plastic model and the leather craft creation elements.

[0007] The present invention is a leather model kit that has a plurality of model member parts in a developed shape corresponding to motifs such as organisms and artifacts. The model member parts have through holes provided at required locations, and by sewing using needles and threads through these through holes, it is characterized in that it can be assembled.

[0008] In addition, in the present invention, it is desirable that the through holes include a first through hole used for sewing with different model member parts and a second through hole used for sewing to form a three-dimensional shape of the model member part itself. With this configuration, since the model member part itself includes a second through hole used for stitching to form a three-dimensional shape, it is possible to add a wavy effect to the model member part itself, or to add thickness partially to form a three-dimensional shape suitable for each part of the member part. By using and assembling them, the completed body is characterized by having holes for forming a three-dimensional shape with various expressions added.

[0009] Furthermore, in the present invention, it is desirable that the through hole further includes a third through hole used for attaching another part different from the model member part. With this configuration, it is possible to fix parts made of plastic, metal, etc. other than the leather material to the completed body to add an expression mode to the completed body or add functions suitable for secondary use purposes. For example, in the case of a leather model with an animal motif, rather than expressing the eyes of the animal with leather members, by inserting and attaching plastic or glass parts for expressing the eyes into the holes, the expressiveness of the motif is improved. Also, by attaching a metal hook to the hole, the completed body can be used as an accessory such as a keyholder or a bag charm, or by attaching a metal button, a function of fixing the lid of the storage case can be added, and the range of secondary use of the completed body can be expanded.

[0010] Moreover, in the present invention, it is desirable that at least one of the plurality of model member parts uses a material in which a core material is lined on the back surface of the leather. With this configuration, not only the shape and dimensions of the through holes formed in the model member parts are maintained, but also the hardness and softness suitable for each part of the model member parts to be formed can be adjusted, and the completed body can be given shape retention and durability.

[0011] The present invention is characterized in that, although the quality of leather such as cowhide, sheepskin, and goatskin varies depending on the variety, such as leather thickness, hardness, and surface touch feeling, by changing the quality such as the thickness and hardness of the polyethylene foam sheet used as the core material for lining and lining, regardless of the quality of the leather, it can be processed into a state suitable as a leather material for the model member parts of the leather model. (Refer to Fig. 5). In addition, since leather is used for the member parts of the cut-out leather model, processing techniques unique to leathercraft such as "stamping" and "branding" that add decorative patterns to the surface can also be applied to the leather model.

[0012] The present invention can form a flat part three-dimensionally by sewing together different leather model member parts cut out from a flat leather sheet material and the through holes provided in the model member parts. It is made possible by sewing the model member parts together with a needle and thread. In a work using an adhesive or the like used in a conventional plastic model, it is difficult to separate the parts once they are combined. However, in the model member parts of the leather model kit, by untying the sewn thread, it can be returned to the state of flat parts any number of times, so that the user can redo the work until they are satisfied with the finish. In addition, since the leather model kit of the present invention comes with a hand-sewing needle and waxed thread for hand-sewing used in leathercraft production, model production can be started immediately after opening. However, by changing the color, thickness, etc. of the waxed thread or arranging the sewing method by the creator (Fig. 4), it is possible to change the finish of the completed product.

[0013] In the present invention, since the model member parts of the leather model kit are made of leather, operations such as bending, twisting, stretching, and rounding the model member parts themselves can be performed, which cannot be expressed in plastic model parts. Therefore, it is characterized by having novelty and progressiveness different from conventional plastic models.

[0014] In addition, it is desirable that the completed product is configured to be able to accommodate an article and includes a case body having an opening and a lid for opening and closing the opening. With this configuration, the completed product can be reused as a storage container.

[0015] Moreover, the method for manufacturing a leather model kit according to the present invention is a method for manufacturing a leather model kit for assembling a completed product having a motif such as a living thing or an artificial object. The method is characterized in that a core material is lined on the back surface of a leather material, and a plurality of model member parts having a developed shape corresponding to each part of the completed product are formed from the leather material lined with the core material, and through holes are formed at required positions of each model member part.

Effects of the Invention

[0016] According to the present invention, it is possible to provide a novel leather model kit that has never existed before and combines the toy-playing elements of conventional plastic models and leathercraft creation elements.

Embodiments for Carrying Out the Invention

[0018] <Configuration of the Leather Model Kit> The leather model kit of the present embodiment is a leather model kit for assembling a completed body with motifs such as living things and artifacts.

[0019] Specifically, as shown in FIGS. 1 to 3, the leather model kit 100 includes a plurality of model member parts 1 to 4, a thread 8 and a needle 7 for sewing these model member parts 1 to 4, and parts 5 and 6 different from the model member parts 1 to 4.

[0020] The model member parts 1 to 4 correspond to each part of the completed body and have a developed shape. Further, the model member parts 1 to 4 are made of leather material. Furthermore, at least one of the plurality of model member parts 1 to 4 uses a material with a core material laminated on the back surface of the leather. Note that the model member parts 1 to 4 are made of leather such as genuine leather or synthetic leather. In addition, any fabric with a quality that does not fray at the cut surface such as genuine leather or synthetic leather may be used.

[0021] In addition, a plurality of through holes a, b, c, d1, d2 are formed in the required positions of the model member parts 1 to 4. Specifically, the through holes a, b, c, d1, d2 include a first through hole d1 used for sewing with different model member parts 1 to 4, second through holes b, d2 used for sewing to form a three-dimensional shape of the model member parts 1 to 4 themselves, and third through holes a, c used for attaching parts 5 and 6 different from the model member parts 1 to 4.

[0022] The model member parts 1 to 4 are stitched together using a needle 7 and a thread 8 with respect to their first through-holes d1, so that the plurality of model member parts 1 to 4 are stitched to each other. Further, the model member parts 1 to 4 are deformed using the needle 7 and the thread 8 with respect to the plurality of second through-holes b and d2 to form a three-dimensional shape. Furthermore, another parts 5 and 6 are fixed to the third through-holes a and c. Thus, a completed body is assembled from the plurality of model member parts 1 to 4 (another parts 5 and 6).

[0023] <Method for manufacturing a leather model kit> Next, a method for manufacturing a leather model kit will be described with reference to FIG. 5. The leather material is die-cut to form the model member parts 1 to 4 so as to have a developed shape corresponding to each part of the completed body. Here, through-holes a, b, c, d1, and d2 are formed at required positions of each of the model member parts 1 to 4.

[0024] When producing the model member parts 1 to 4 with a core material lined on the back surface of the leather, for example, a polyethylene foam sheet serving as the core material is attached to the back surface of the leather material with an adhesive for lining. Then, the leather material with the core material attached is die-cut to form the model member parts 1 to 4 so as to have a developed shape corresponding to each part of the completed body.

[0025] Together with the model member parts 1 to 4 formed as described above, another parts 5 and 6, a needle 7, and a thread 8 are packaged to manufacture a leather model kit.

Example

[0026] Figure 1 is a completed drawing depicting the assembled form of the component parts (Figure 2) that make up the leather model kit "Kotori" of this embodiment from four directions. Figure 3 is a process diagram of the assembly of the leather model kit "Kotori". Figure 7 is an image of the actual completed product of the leather model kit "Kotori" in Figures 1 - 3, and headings 12 - 15 are images viewed from each direction. The reference numerals 1 - 6 in Figures 1 - 3 and the reference numerals a - d in Figures 2 and 3 are the names of the respective component parts that make up the leather model kit "Kotori". The reference numeral 7 in Figure 2 indicates a hand-sewing needle, and the reference numeral 8 indicates sewing thread. In the case of the leather model kit "Kotori", the above eight components are configured as one kit, and the creator can create the completed product by simply preparing scissors for cutting the thread. Also, in other leather model kits, although the number of component parts configured is different, the completed product can similarly be created by simply preparing scissors separately.

Embodiment

[0027] Figure 5 is a manufacturing process diagram of the materials of the model component parts 1 - 4 used in this embodiment and the production process up to the creation of the model component parts using those materials. P - 1 is a diagram of placing the leather material 9 on the polyethylene foam sheet 10 which is the backing material.

[0028] P - 2 is a manufacturing process diagram of backing the leather material 9 with the polyethylene foam sheet 10 coated with an adhesive by applying pressure from above in the state where the leather material 9 is placed on the polyethylene foam sheet 10.

[0029] P - 3 is a manufacturing process diagram of cutting out parts 1 - 4 with a die 11 for cutting out the model component parts 1 - 4 of the leather model kit by placing the die 11 on P - 2 and using a press machine. Note that as a feature of the die 11 for the leather model kit, in addition to cutting out the outer shape, through-holes necessary for assembly are simultaneously cut out at the required positions within parts 1 - 4, in the required number at the predetermined positions for each of the model component parts 1 - 4.

[0030] P-4 shows the state diagrams of the cut-out parts 1 to 4 (here, only part 3 is shown). 3-a shows the state when the leather side is on the surface, and 3-b shows the state when the polyethylene foam sheet side is on the surface. Also, although leather is originally a material that is vulnerable to moisture, since there is no process of using moisture-containing materials even in the manufacturing process of the leather model member parts and during the fabrication of the leather model kit, it is characteristic that the model member parts 1 to 4 can be used for fabrication while maintaining the quality of the leather material 9.

Example

[0031] In this example, the model member parts of the leather model kit may be used without lining depending on the motif of the model. Q-6 in Fig. 6 is an example of the assembly of the member parts and is a plan image of the fin model member part that does not undergo the lining process used in the leather model kit "goldfish". Q-7 is working on the wavy state of the fin by sewing together the predetermined holes in the fin model member part of Q-6 while folding. The model member parts in Fig. 6 prioritize expressing a shape with a stronger sense of unevenness rather than shape retention. By using unlined model member parts, an irregular fin is fabricated, and free movement can be given even after completion.

[0032] Fig. 8 shows, as an example, the completed image of the leather model kit "goldfish" of this example, with the color or type of leather used for the model member parts changed. By doing so, it is possible to obtain a completed product with a different atmosphere while keeping the shape of the completed product the same, and the variations of the leather model kit can be increased.

[0033] For example, in headings 16 and 18 of FIG. 8, since sheepskin is used as the member part material, it becomes a finished leather product with a smooth surface and elasticity, which are characteristics of sheepskin. On the other hand, in heading 17, since metallic-finished cowhide is used as the member part material, due to the influence of the firm and tightened leather texture with strong tension of the material, which is a characteristic of cowhide, the finished product has a distinct contour. Also, in heading 19, since vegetable-tanned cowhide (nume leather) is used as the member part material, over time, the surface of the finished product gradually changes to a caramel color. These are completely new and different from conventional plastic model kits.

[0034] For the model member parts of the leather model kit in this embodiment, by using paints such as acrylic paints corresponding to the painting of leather materials, it is also possible to draw patterns or color the surface of the finished product (heading 17 in FIG. 8), and it is also possible to enjoy the painting expression of conventional plastic model kits as a craft.

[0035] This embodiment is not merely aimed at simply decorating the finished model, but can also increase the utility value by adding functions structurally. The image in heading 20 of FIG. 9 is an example of the secondary use of the leather model kit "goldfish". The finished "goldfish" can be separated into a part serving as a lid and a part serving as a case, and has the function of storing small items inside. That is, the finished product is configured to be able to accommodate items and has a case body with an opening and a lid for opening and closing the opening. Headings 21 and 22 of FIG. 9 are examples of the secondary use of the leather model kit "bird". By attaching a metal hook part to the back of the finished form, it can be reused as a bag charm to be attached to a bag as shown in heading 21 and as a keyholder as shown in heading 22 respectively. The ways of secondary use are not limited to these, and various use methods such as a piggy bank, a tissue cover, and a wallet can be considered.

[0036] The leather model kit of this embodiment is the leather model kit described in the above paragraph 0021. Although there are multiple variations for each motif of the completed product, the difficulty of model making also varies depending on each motif. For example, in the leather model kit "bird", the difficulty of making can be adjusted by reducing the number of component parts or the assembly process of the model member parts so that children can assemble them. Considering the opportunity for children to make, the sewing needles included in all leather model kits can also be enclosed with the needle tips crushed in consideration of the danger of handling. Also, in the sewing practice in elementary schools, sewing a cloth neatly using needles and threads is a difficult task for children. However, in the case of leather model kits, through holes for sewing are provided in advance on the model member parts, so even children can easily assemble them. As a result, it is easy to obtain "the joy of making and the sense of achievement of completion", which leads to an improvement in "the creative desire for manufacturing".
