Description

Technical Field

[0001] This invention relates to the field of mattress technology, and more particularly to a corner stitching process, a mattress cover, and a mattress. Background Technology

[0002] To ensure sleep comfort, a mattress is usually placed on the bed frame. A mattress generally consists of a mattress cover and a mattress core. The mattress cover is placed over the mattress core, which not only makes the user experience more comfortable, but also makes the mattress look neat and tidy.

[0003] like Figure 1 and Figure 2 As shown, in the manufacturing process of mattress covers, the four corners are typically finished by folding the adjacent sides of the cut piece in half, then sewing a line to form seam line 1'; the portion beyond 1.5cm from seam line 1' is then cut off; simultaneously, to ensure mattress quality, the edge 1.5cm from the seam line needs to be overlocked. In other words, processing one corner of a mattress cover requires three steps: sewing, cutting, and overlocking. This cumbersome process results in low efficiency in mattress cover manufacturing. Furthermore, the sewn seams are prone to cracking and other quality issues during long-term use. Summary of the Invention

[0004] The purpose of this invention is to provide a corner-stitching process, a mattress cover, and a mattress, so as to solve the technical problems of low processing efficiency and potential quality risks of mattress covers in the prior art.

[0005] Based on the above concept, the technical solution adopted by this invention is as follows:

[0006] The corner beveling process includes the following steps:

[0007] S1. Fold the adjacent two sides of the cut piece at a set angle;

[0008] S2. Select a first line segment, the first line segment is perpendicular to the overlapping edge formed by folding, and the distance of the first line segment from the vertex formed by folding is a first set distance;

[0009] S3. Select a second line segment, which is perpendicular to the first line segment. The second line segment is located within the triangular area formed by the vertex and the first line segment. The distance between the second line segment and the overlapping edge formed after folding is a second set distance.

[0010] S4. Sew along the second line segment to form a seam line;

[0011] S5. Fold the triangular region toward the rest of the region along the first line segment;

[0012] S6. Sew the triangular region and a layer of fabric in contact with the triangular region together.

[0013] Optionally, the set angle is 45°.

[0014] Optionally, the first set distance is not less than 6.5cm.

[0015] Optionally, the second set distance is not less than 1.5cm.

[0016] Optionally, in step S4, backstitching is required for both the start and finish stitches.

[0017] Optionally, the corner-making and sewing process includes: processing the four corners of the cut piece one by one using steps S1-S6.

[0018] Optionally, the corner beveling process further includes the following steps:

[0019] S7. Install the zipper.

[0020] The mattress cover is formed using the aforementioned corner-making and sewing process.

[0021] Optionally, the mattress cover includes an upper fabric and a lower fabric, which can be closed to form an accommodating cavity, and both the upper fabric and the lower fabric are formed by the corner-stitching process.

[0022] A mattress, including a mattress core and the aforementioned mattress cover, wherein the mattress cover is fitted over the outer periphery of the mattress core.

[0023] The beneficial effects of this invention are:

[0024] The corner-stitching process proposed in this invention can process the corners of mattress covers. When processing a corner, the adjacent two sides of the cut piece are folded at a set angle; a first line segment is selected, which is perpendicular to the overlapping edge formed by the fold, and the distance between the first line segment and the vertex formed by the fold is a first set distance; then a second line segment is selected, which is perpendicular to the first line segment, and the second line segment is located within the triangular area formed by the vertex and the first line segment, and the distance between the second line segment and the overlapping edge formed after the fold is a second set distance; then, the second line segment is sewed to form a stitch line; next, the triangular area is folded towards the rest of the area along the first line segment; finally, the triangular area and the layer of fabric in contact with the triangular area are sewn together.

[0025] This corner-stitching process only requires sewing; cutting and overlocking are unnecessary, improving the processing efficiency of mattress covers. Furthermore, because no cutting or overlocking is required, the stitching will not come loose or float at the seam, reducing the risk of cracking and ensuring the product's aesthetics and quality.

[0026] The mattress cover proposed in this invention is manufactured using the aforementioned corner-stitching process. This corner-stitching process only requires sewing; cutting and hemming are unnecessary, thus improving the processing efficiency of the mattress cover. Furthermore, since cutting and hemming are not required, the stitching will not come loose or float at the seam, reducing the likelihood of cracking and ensuring the product's aesthetics and quality.

[0027] The mattress proposed in this invention includes a mattress core and a mattress cover, which is fitted around the outer periphery of the mattress core. The mattress cover of this invention has high processing efficiency, and the mattress maintains both aesthetic appeal and product quality. Attached Figure Description

[0050] Example 1

[0051] See Figures 3-9 This embodiment provides a corner-making and sewing process.

[0052] It can be used in the processing of mattress covers, reducing steps and improving production efficiency.

[0053] Specifically, in this embodiment, the corner beveling process includes the following steps:

[0054] S1. Fold the two adjacent sides of the cut piece 1 at a set angle.

[0055] It is understood that the cut piece 1 is the fabric that forms the mattress cover. Specifically, in this embodiment, the mattress cover includes an upper fabric 10 and a lower fabric 20; correspondingly, before processing the mattress cover, the mattress cover includes two cut pieces 1, and the corners of the upper fabric 10 and the lower fabric 20 can be processed using the corner-making sewing process.

[0056] Optionally, see Figure 4 and Figure 5 In this embodiment, the angle is set to 45°.

[0057] S2. Select the first line segment 2, which is perpendicular to the overlapping edge formed by the fold, and the distance between the first line segment 2 and the vertex formed by the fold is the first set distance a.

[0058] Specifically, see Figure 6 The vertex formed by folding is point A, line segment AB represents the overlapping edge formed by folding, the first line segment 2 is perpendicular to line segment AB, and the distance of the first line segment 2 from point A is the first set distance a.

[0059] Optionally, the first set distance a is not less than 6.5cm.

[0060] Preferably, the first set distance a is 6.5cm.

[0061] S3. Select the second line segment 3. The second line segment 3 is perpendicular to the first line segment 2. The second line segment 3 is located in the triangular region 11 formed by the vertex and the first line segment 2. The distance of the second line segment 3 from the overlapping edge formed after folding is the second set distance b.

[0062] Specifically, the two ends of the first line segment 2 are points C and D, respectively. Connecting point A to the two ends of the first line segment 2 forms triangle ACD. The second line segment 3 is perpendicular to the first line segment 2 and lies within triangle ACD. The distance of the second line segment 3 from line segment AB is a second predetermined distance b.

[0063] Optionally, the second set distance b is not less than 1.5 cm. Specifically, in this embodiment, the second set distance b is 1.5 mm.

[0064] S4. Sew along the second line segment 3 to form a seam line.

[0065] In step S4, backstitching is required for both the start and finish stitches.

[0066] Specifically, after step S4 is completed, the two folded pieces of fabric are sewn together along the second line segment 3.

[0067] Specifically, the first line segment 2 coincides with the end of the backstitch.

[0068] S5. Fold the triangular region 11 toward the remaining region 12 along the first line segment 2.

[0069] S6. Sew the triangular region 11 and the layer of fabric in contact with the triangular region 11 together.

[0070] It is understandable that after folding the triangular area 11 towards the other areas 12 along the first line segment 2, there are a total of four layers of fabric. Two of these layers are the part of triangle ACD, and the other two layers are the rest. The two layers of fabric of triangle ACD and the one layer of fabric on the other area 12 adjacent to triangle ACD are then sewn together.

[0071] Specifically, in step S6, the triangular area 11 and the layer of fabric in contact with the triangular area 11 are sewn perpendicularly, 1.5cm from the edge, and backstitching is required for the start and end.

[0072] The corner stitching process provided in this embodiment can process the corners of a mattress cover. When processing a corner, the adjacent two sides of the cut piece 1 are folded at a set angle; a first line segment 2 is selected, which is perpendicular to the overlapping edge formed by the fold, and the distance between the first line segment 2 and the vertex formed by the fold is a first set distance a; then a second line segment 3 is selected, which is perpendicular to the first line segment 2, and the second line segment 3 is located within the triangular area 11 formed by the vertex and the first line segment 2, and the distance between the second line segment 3 and the overlapping edge formed after the fold is a second set distance b; then, the second line segment 3 is stitched to form a stitch line; next, the triangular area 11 is folded towards the remaining area 12 along the first line segment 2; finally, the triangular area 11 and the layer of fabric in contact with the triangular area 11 are sewn together.

[0073] This corner-stitching process only requires sewing; cutting and overlocking are unnecessary, improving the processing efficiency of mattress covers. Furthermore, because no cutting or overlocking is required, the stitching will not come loose or float at the seam, ensuring the product's aesthetic appeal.

[0074] Furthermore, in this embodiment, the corner-making and sewing process includes: processing the four corners of the cut piece 1 one by one using steps S1-S6.

[0075] Since the mattress cover consists of an upper fabric 10 and a lower fabric 20, in order to connect the upper fabric 10 and the lower fabric 20, in this embodiment, the corner-stitching process further includes the following steps:

[0076] S7. Install zipper 4.

[0077] Specifically, after the four corners of the upper fabric 10 are processed, a zipper 4 is installed on the upper fabric 10; after the four corners of the lower fabric 20 are processed, a zipper 4 is installed on the lower fabric 20.

[0078] The zipper 4 on the upper fabric 10 and the zipper 4 on the lower fabric 20 can be locked together. The mattress cover is placed around the mattress core to protect it.

[0079] Example 2

[0080] See Figures 7-9 This embodiment provides a mattress cover, which is formed using the corner-stitching process described in Embodiment 1.

[0081] Specifically, in this embodiment, the mattress cover includes an upper fabric 10 and a lower fabric 20, which can be closed to form an accommodating cavity. Both the upper fabric 10 and the lower fabric 20 are formed by corner beveling.

[0082] For example, taking a single-layer mattress cover measuring 180cm×200cm×10cm as an example, the upper fabric 10 and the lower fabric 20 have the same size cut pieces and the same processing technology.

[0083] Specifically, the dimensions of cut piece 1 are: 193cm (1.5cm+5cm+180cm+5cm+1.5cm) in the width direction and 213cm (1.5cm+5cm+200cm+5cm+1.5cm) in the length direction.

[0084] Figure 10 The dimensions of cut piece 1 are shown in the diagram; it should be noted that, Figure 10 The unit is mm; Figure 10 This is for dimensional illustration only and is not a scale representation. Figure 10 Please refer to the dimensions marked on the paper. Leave allowance at all four corners of cut piece 1 for processing.

[0085] When processing a corner, fold the two adjacent sides of the cut piece 1 at a 45° angle; select the first line segment 2, which is perpendicular to the overlapping edge formed by the fold, and the distance between the first line segment 2 and the vertex formed by the fold is a first set distance a; then select the second line segment 3, which is perpendicular to the first line segment 2, and the second line segment 3 is located in the triangular area 11 formed by the vertex and the first line segment 2, and the distance between the second line segment 3 and the overlapping edge formed after the fold is a second set distance b; then sew along the second line segment 3 to form a seam line; next, fold the triangular area 11 towards the other areas 12 along the first line segment 2; finally, sew the triangular area 11 and the layer of fabric in contact with the triangular area 11 together.

[0086] Specifically, in this embodiment, when the adjacent sides of the cut piece 1 are folded at a 45° angle, the right side of the cut piece 1 faces inward. After the zipper 4 is installed, the sewn upper fabric 10 (or lower fabric 20) is turned over.

[0087] Example 3

[0088] This embodiment provides a mattress, including a mattress core and a mattress cover as described in Embodiment 2, the mattress cover being fitted around the outer periphery of the mattress core.

[0089] The mattress cover is manufactured with high efficiency and ensures the mattress's aesthetic appeal.
