[0033] The present invention will be further described below with reference to the examples, but are not intended to limit the present invention.
[0034] Referring to Figures 1 to 3 , the template for the disposable single-sided elastic cord of a riding cuff and a riding strap in this embodiment includes a base plate 1 , a cover plate 2 , and an extension plate 3 . To facilitate observation of the position of the pieces to be sewn when using the template and to facilitate detection of sewing errors, the base plate 1 , the cover plate 2 , and the extension plate 3 are all made of transparent PVC sheets.
[0035] The base plate 1 and the cover plate 2 are two rectangular plates, connected along one side of their length by a connecting strip 4, forming a foldable structure. In other words, the cover plate 2 can be folded along the connecting line between the cover plate 2 and the base plate 1 and stacked on the base plate 1. In a preferred embodiment, the cover plate 2 and the base plate 1 are made of the same size, but this is not required.
[0036] A first sewing hollow groove consisting of a plurality of strip holes is provided on the base plate 1, and a second sewing hollow groove consisting of a plurality of strip holes is provided on the cover plate 2. The first sewing hollow groove and the second sewing hollow groove are mirror-imaged with the connecting line between the cover plate 2 and the base plate 1 as the axis. It should be pointed out that the correspondence between the first sewing hollow groove and the second sewing hollow groove is mainly to meet the requirement of the upper and lower penetration of the sewing needle during sewing. Therefore, the first sewing hollow groove and the second sewing hollow groove do not need to be strictly and completely corresponded.
[0037] In order to facilitate a detailed introduction to the specific position structure of the first sewn hollow groove and the second sewn hollow groove, the different parts on the bottom plate 1 are first described below.
[0038] The base plate 1 primarily includes two positioning areas: the sleeve loop positioning portion A and the elastic positioning portion B. Both the sleeve loop positioning portion A and the elastic positioning portion B are approximately rectangular in shape and are arranged side by side in the length direction. In this embodiment, the sleeve loop positioning portion A and the elastic positioning portion B have aligned right ends. Furthermore, the sleeve loop positioning portion A primarily serves to position the sleeve loop, while the elastic band is located on one side of the cuff (opposite the sleeve loop). Therefore, the elastic positioning portion B is longer than the sleeve loop positioning portion A.
[0039] On the part of the base plate 1 located at the sleeve loop positioning portion A, a frosted strip is used to surround the outer contour of the sleeve loop and adhered to the base plate 1 to form a sleeve loop positioning line 5. The sleeve loop positioning line 5 is slightly raised from the base plate 1. On the one hand, it forms a limiting structure to facilitate the positioning and placement of the sleeve loop. On the other hand, when the cuff fabric is placed on the base plate 1, it contacts the sleeve loop positioning line 5 to increase friction, which can prevent the piece from shifting when the cover plate 2 is closed, thereby improving accuracy.
[0040] A fabric reference positioning line 6 is provided on the base plate 1, along one side of the elastic positioning portion B in the longitudinal direction. For ease of description, the two sides of the elastic positioning portion B in the longitudinal direction are defined as a first side a and a second side b, where the first side a is the side of the elastic positioning portion B adjacent to the sleeve loop positioning portion A. Similar to the sleeve loop positioning line 5, the fabric reference positioning line 6 is formed by a frosted strip adhered to the base plate 1 along the second side b of the elastic positioning portion B. The fabric reference positioning line 6 also slightly protrudes from the base plate 1. When the fabric is placed, the edges of the cut pieces are placed along the fabric reference positioning line 6. Similarly, the friction between the fabric reference positioning line 6 and the cut pieces prevents them from shifting when the cover plate 2 is closed, thereby improving accuracy.
[0041] The elastic retaining portion B is used to cooperate with the extension plate 3 to secure the elastic band and maintain a certain stretched length. As shown in Figure 5, the first elastic connector 7 and the first extension plate connector 9 are respectively provided at each end of the elastic retaining portion B in the longitudinal direction. The second elastic connector 8 and the second extension plate connector 10 are respectively provided at each end of the extension plate 3 in the longitudinal direction. The first elastic connector 7 and the second elastic connector 8 are used to removably connect to the ends of the elastic band. The first extension plate connector 9 and the second extension plate connector 10 cooperate to removably connect one end of the extension plate 3 to the base plate 1. In this embodiment, the first elastic connector 7, the second elastic connector 8, and the first extension plate connector 9 all feature a rivet 11 structure. Specifically, multiple rivets 11 are positioned substantially perpendicular to the base plate 1 or the extension plate 3. The second extension plate connector 10 comprises a through hole 12 formed in the extension plate 3. These through holes 12, in conjunction with the rivets 11, allow the right end of the extension plate 3 to be hooked onto the first extension plate connector 9, forming a removable connection with the base plate 1. The first elastic connector 7 and the second elastic connector 8 pierce the elastic band, forming a removable connection. When the extension plate 3 is connected to the base plate 1, the spacing between the first elastic connector 7 and the second elastic connector 8 is greater than the natural length of the elastic band. In other words, after the left end of the elastic band is connected to the base plate 1 and the right end of the elastic band is connected to the left end of the extension plate 3, the elastic band needs to be stretched to connect the left end of the extension plate 3 to the base plate 1.
[0042] In a preferred embodiment, in order to facilitate folding the piece and determine whether it is folded in place, a folding center line 13 is provided on the base plate 1 between the sleeve loop positioning portion A and the elastic positioning portion B. The folding center line 13 can be simply a mark on the base plate 1.
[0043] As mentioned above, the first sewn hollow groove and the second sewn hollow groove are mirror-imaged, so the structure is introduced taking the first sewn hollow groove as an example, and the second sewn hollow groove can be obtained by mirror-reversing the first sewn hollow groove.
[0044] The first sewn hollow slot includes a first row of holes 13, a second row of holes 14, a third row of holes 15, a fourth row of holes 16, and a fifth row of holes 17. As previously mentioned, the two sides of the lengthwise direction of the elastic locating portion B are the first side a and the second side b. Therefore, the first side a and the second side b are arranged opposite each other. The sleeve loop locating portion A is located on the first side a of the elastic locating portion B. Therefore, one side of the lengthwise direction of the sleeve loop locating portion A is defined as the first side a, while the other side of the lengthwise direction of the sleeve loop locating portion A is defined as the third side c. In this embodiment, to facilitate alignment of the cover plate 2 and the opening and closing, the third side c, the first side a, and the second side b are positioned from proximal to distal and parallel to the connecting line between the cover plate 2 and the base plate 1. The first row of holes 13 is arranged along the third side c. The second row of holes 14 is arranged along the right end of the sleeve loop locating portion A, perpendicular to the first row of holes 13. The third row of holes 15 is arranged along the second side b. The fourth hole 16 is located in the middle of the elastic locating portion B and is arranged along the length of the elastic locating portion B. The tip of the fourth hole 16 is at the left end of the elastic locating portion B, and the tip of the fourth hole 16 extends to a position roughly flush with the left end of the sleeve loop locating portion A. The fifth hole 17 is arranged along the width of the elastic locating portion B and is located at the junction of the stretched elastic band and the extension plate 3, that is, approximately at the left end of the sleeve loop locating portion A. The fifth hole 17 is arranged perpendicular to the third hole 15.
