A leather handle and a product containing it

Abstract

A leather handle and a product containing the same are disclosed. The handle is constructed from the outside in, comprising an overlapping leather layer, an EVA material layer, and a webbing layer. Each leather layer has a folded edge on both sides along its width direction. The folded edges are folded inward to partially cover the EVA material layer, and the webbing layer covers the space between the two folded edges. The leather layer, EVA material layer, and webbing layer are folded together along their width direction from the center seam, causing the two folded edges to overlap. The overlapped two folded edges are then sewn together to form the handle body. This invention eliminates the need for an edge-painting structure, thus avoiding debris and peeling, and effectively improving the overall wear resistance and service life of the handle.

Description

Technical Field

[0001] This application relates to the technical field of bags or pouches, specifically to a leather handle and a product containing the same. Background Technology

[0002] Currently, most bags and pouches on the market have handles on the top for easy use and retrieval; these handles are usually made of leather, as shown in the attached image. Figure 1-3 As shown, specifically from the appendix Figure 3 As can be seen, most of these structures involve overlapping leather layers 1' to form a handle, with an edge oil 7' applied along the thickness direction of one overlapping edge. In other words, existing technology directly coats the leather layer's thickness direction with edge oil 7' (edge ​​oil) for edge treatment. However, all of these edge oiling processes will encounter issues such as peeling and chipping after prolonged use due to the performance of the edge oil. This is because the edge oil is applied to the leather's thickness direction, i.e., the edge of the leather. If the edge oil's performance is poor, or due to environmental factors such as contact with sweat, washing, prolonged sun exposure, or repeated handling and friction, the edge oil will chip, peel, fade, or crack. Once these issues occur, they will severely affect the handle's usability. Furthermore, as shown in the attached... Figure 2 As shown, the existing technology involves sewing the handle directly to the bag body 6' using the sewing thread 4'. This method can easily cause the sewing to break, affecting the use of the handle. Utility Model Content

[0003] This application addresses the aforementioned shortcomings of the prior art by providing a leather handle that does not require an oiled edge structure, thereby avoiding debris and peeling, and effectively improving the overall wear resistance and service life of the handle.

[0004] To solve the above-mentioned technical problems, the technical solution adopted in this application is as follows: a leather handle, the structure of which is provided from the outside to the inside with an overlapping leather layer, an EVA material layer and a webbing layer; the leather layer has a folded edge on both sides along its width direction, the folded edge is folded inward to partially cover the EVA material layer, and the webbing layer covers the gap between the two folded edges; the leather layer, EVA material layer and webbing layer are folded together from the center seam along the width direction so that the two folded edges overlap each other, and the two folded edges are sewn together to form the handle body.

[0005] By adopting the above structure, this application abandons the traditional edge paint and edge finishing process, and directly sets a folded edge on each side of the leather layer in the width direction. Then, the leather layer, EVA material layer and webbing layer are folded together from the center seam along the width direction so that the two folded edges overlap. After overlapping, the overlapping folded edges are sewn together along the thickness direction to form a complete leather handle. There is no edge paint in this handle structure. Instead, the folded edge structure formed by the leather layer will not cause the shedding of debris. This structure effectively improves the wear resistance and service life of the overall handle. The edges will not fade or break, making it more durable. Moreover, only the two overlapping folded edges of the entire handle are sewn together with stitching. The rest is completely wrapped by the leather layer. Therefore, this structure further enhances the durability of the entire handle.

[0006] Furthermore, the two folded edges have equal extension widths; this structure allows the overlapping folded edges to be effectively supported, improving the wear resistance of the sewn cover handle edge.

[0007] Furthermore, the width of the folded edge is not greater than the width of the webbing layer; by adopting this structure, a webbing layer of a certain width can be set in the inner layer to improve the overall handle's flexibility.

[0008] Furthermore, the width of the webbing layer is adapted to the spacing between the two folded edges; with this structure, after the folded edges and webbing layer cover the EVA material layer, the EVA material layer can be completely covered, thereby avoiding any gaps that would affect the smoothness of the sewing and handle.

[0009] Furthermore, the thickness of the webbing layer is adapted to the thickness of the folded edge; this structure ensures that the thickness of the superimposed composite layer is equal at all positions after folding from the center seam, maintaining the flatness of the handle during the sewing process.

[0010] Furthermore, the stitching line is located near the outer edge of the folded edge; this structure allows the two folded edges to be sewn tightly together, avoiding an excessively wide opening between them that would affect the grip feel.

[0011] Furthermore, both ends of the handle body are connected to the bag body via sewing modules. Each sewing module includes a leather layer that covers the ends of the handle body, and the leather layer is sewn to the bag body around its perimeter. Using this structure, instead of directly sewing the handle body to the bag body, this application uses a combination of sewing thread and leather layer to completely cover the ends of the handle body. This disperses the tensile force at the horizontal sewing line between the handle end and the bag body onto the sewing module, effectively protecting the ends and preventing breakage.

[0012] Furthermore, the leather layer is surrounded by an edge paint. With this structure, since the sewing module has a small area and does not need to be in direct contact with the hand, the edge paint will not fall off or crumble, thus maintaining the overall visual effect of the handle.

[0013] This application also provides a handbag product containing the leather handle described above. Handbags using this leather handle will not experience wear and tear or chipping on the handle edges during use, and will also enhance the strength and toughness of the handle, increasing its service life. Furthermore, the handle is connected to the bag body via a sewn-on module, which effectively disperses the pulling force exerted by the bag body on the handle, reducing the risk of handle breakage.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] As attached Figure 1-8As shown, this application discloses a novel leather handle. The handle's structure, from the outside in (i.e., the handle has a multi-layered structure, from the outermost layer directly in contact with the hand to the innermost layer), comprises overlapping layers: a leather layer 1, an EVA material layer 2 (a copolymer of ethylene and vinyl acetate, a commercially available material), and a webbing layer 3 (which can be a sheet woven from resilient yarn, or a readily available resilient fabric layer or woven material). The leather layer 1 has a folded edge 101 on both sides along its width direction. The folded edges 101 are folded inwards to partially cover the EVA material layer 2. The webbing layer 3 covers the gap between the two folded edges. The inner layer (webbing layer 3 is used to cover the inner EVA material layer 2); the leather layer 1, EVA material layer 2 and webbing layer 3 are folded together along the width direction from the center seam position (the center seam is the center seam extending along the length extension direction of the leather layer 1) so that the two folded edges 101 overlap each other, and the two folded edges 101 are sewn together by the sewing thread 4 to form the handle body a; specifically, the handle body a of this application includes three material layers, the innermost layer is the webbing layer 3 and the two inwardly folded edges 101, the middle layer is the EVA material layer 2, and the outermost layer is the leather layer 1. Then, the side near the folded edge 101 is sewn along the length direction of the handle body a by the sewing thread 4 to sew the material after the center seam folding into a complete handle body a (see details). Figure 5 (As shown).

[0028] By adopting the above structure, this application abandons the traditional edge oiling and edge finishing processes. Instead, a folded edge is directly set on each side of the leather layer in the width direction. Then, the leather layer, EVA material layer, and webbing layer are folded together from the center seam along the width direction, so that the two folded edges overlap. After overlapping, the overlapping folded edges are sewn together along the thickness direction to form a complete leather handle. There is no edge oil in this handle structure; instead, the folded edge structure formed by the leather layer replaces it. Since there is no edge oil layer, there will be no shedding or debris. This structure effectively improves the wear resistance and service life of the overall handle, and the edges will not fade or break, making it more durable. Moreover, only the two overlapping folded edges of the entire handle are sewn together with stitching, while the rest is completely wrapped by the leather layer. Therefore, this structure further enhances the durability of the entire handle.

[0029] As attached Figure 7-9 As shown, the two folded edges 101 described in this application have equal extension widths, that is, the folded edges on the left and right sides in the width direction are of equal width; by adopting this structure, the overlapping strip folded edges are effectively supported by each other, improving the wear resistance of the edge of the sewn cover handle.

[0030] As attached Figure 7-9 As shown, the width of the folded edge 101 described in this application is not greater than the width of the webbing layer 3, that is, the extension width of the webbing layer 3 is greater than or equal to the extension width of the folded edge 101 on one side; by adopting this structure, a webbing layer of a certain width can be set in the inner layer to improve the flexibility of the overall handle.

[0031] As attached Figure 7-9 As shown, the width of the webbing layer 3 described in this application is adapted to the spacing between the two folded edges 101; that is, after the two folded edges 101 are folded over and covered onto the EVA material layer 2, the gap formed between them is covered by the webbing layer 3, thereby completely covering the inner surface of the entire EVA material layer 2 through the folded edges 101 and the webbing layer 3; with this structure, when the folded edges and the webbing layer are covered onto the EVA material layer, the EVA material layer can be completely covered, thereby avoiding the presence of hollowed-out areas that would affect the smoothness of the sewing and the handle.

[0032] As attached Figure 7-9 As shown, the thickness of the webbing layer 3 described in this application is adapted to the thickness of the folded edge 101, that is, the two are of equal thickness; by adopting this structure, the thickness of each position of the superimposed composite layer formed after folding from the center seam can be equal, and the flatness of the handle can be maintained during the sewing process.

[0033] As attached Figure 9 As shown, the stitching line 4 described in this application is close to the outer edge of the folded edge 101; with this structure, the two folded edges can be sewn tightly to avoid an excessively wide opening between them, which would affect the grip feel.

[0034] As attached Figure 4 , Figure 6 and Figure 9 As shown, the two ends of the handle body a described in this application are connected to the bag body 6 via sewing modules 5. The sewing module 5 includes a leather layer that covers the ends of the handle body a, and the leather layer is sewn to the bag body 5 around its perimeter using stitching thread 4. The leather layer and the leather layer used to prepare the handle body can be made of the same material and can be cut into a rectangular structure to cover and sew the two ends of the handle body a together with the bag body. Using this structure, this application does not directly sew the handle body onto the bag body, but rather completely covers the ends of the handle body using a combination of stitching thread and leather layer. This disperses the tensile force at the horizontal stitching line between the handle end and the bag body onto the sewing module, effectively protecting the ends and preventing breakage.

[0035] As an example, the leather layer in the sewing module 5 of this application is provided with an edge paint, that is, after the leather layer is sewn onto the bag body, the four edges of the leather layer are treated with an edge paint along the thickness direction, which is the edge paint process of the existing bag handle; with this structure, since the sewing module has a small area and does not need to be in direct contact with the hand, the edge paint will not fall off or break off, thus maintaining the overall visual effect of the handle.

[0036] As attached Figure 4 This application also provides a handbag product containing the leather handle described above. Handbags using this leather handle will not experience wear and tear on the handle edges or produce debris during use. Furthermore, the overlapping and stitched structure of the folded edges enhances the strength and toughness of the handle, increasing its lifespan. In addition, the connection between the handle and the bag body is a directly sewn module, effectively dispersing the pulling force exerted by the bag body on the handle and reducing the risk of handle breakage.

[0037] The handle structure of this application, through a combination of folded edges and stitching, eliminates the need for traditional edge paint. This primarily addresses the technical problems of existing edge paints easily wearing down, producing flakes or flaking during use. This application employs a handle structure constructed from folded leather edges... Figure 5 The handle structure shown is illustrated in the diagram below. Figure 7-8 As shown, the handle consists of an outermost leather layer, a middle EVA material layer, and an innermost webbing layer. The leather layer needs to be folded inwards from both sides to form two folded edges, so that the outer side completely covers the EVA material layer and the inner side partially covers the EVA material layer. The function of the EVA material layer in this application is mainly to improve the feel of the product when gripping it. Then, the webbing layer covers the areas not covered by the folded edges to improve the overall toughness and strength of the handle; and as shown in the attached... Figure 4 , Figure 6 As shown, the sewing module used connects the handle and the bag body, mainly to improve the handle's folding resistance. Specifically, it is formed by sewing a rectangular piece of leather onto the bag body, and then the edges of the leather layer are finished with edge dressing along the thickness direction.
