Description

Technical Field

[0001] The invention discloses a patch with a reverse tensioning and tightening device sewn on a car cover, and relates to the field of automobile supplies. Background Art

[0002] The existing car cover with a tightening device is extremely inconvenient to manufacture directly on a bulky car cover, and the workmanship and efficiency are difficult to meet the standards. In addition, the force is applied in one direction, and the tightening effect is poor. Summary of the Invention

[0003] The utility model aims to design a garment tight device which is made in the form of a patch and can be sewn on the hem of a garment.

[0004] The utility model is composed of a base sheet 1, a tightening device, a car cover 2 and a car cover hem 3. The base sheet 1 is a long sheet material, or cotton yarn or chemical fiber, which can be sewn and hot pressed. A fixing force point 4 is set in the horizontal middle of the base sheet 1, which is the starting point for fixing the left hook reinforcement 5 and the right hook reinforcement 6 respectively. One point is connected to two points, and the left hook reinforcement 5 and the right hook reinforcement 6 are relatively opposite. On the left side of the fixing force point 4, in front of the base sheet 1 facing the left hook reinforcement 5, at least one left fixing pull ring 7 is made. The left hook reinforcement 5 can be hooked in it. On the right side of the fixing force point 4, in front of the base sheet 1 facing the right hook reinforcement 6, at least one right fixing pull ring 8 is made. The right hook reinforcement 6 can be hooked in it. When the left hook rib 5 hooks onto the left retention ring 7, the base sheet 1 contracts rightward from the retention point 4 due to the elastic force, that is, the distance between the retention point 4 and the left retention ring 7 is shortened. After the base sheet 1 is sewn onto the car cover 2, it drives the hem 3 of the car cover to contract inward, that is, to the right, thereby tightening the car cover 2. When the right hook rib 6 hooks onto the right retention ring 8, the base sheet 1 contracts leftward from the retention point 4 due to the elastic force, that is, the distance between the retention point 4 and the right retention ring 8 is shortened. After the base sheet 1 is sewn onto the car cover 2, it drives the hem 3 of the car cover to contract inward, that is, to the left, thereby tightening the car cover 2. When the left and right hook ribs 5 and 6 simultaneously hook onto the left and right retention rings 7 and 8, the hem 3 of the car cover, located on the left and right sides of the car body and between the front and rear wheels, simultaneously contracts toward the center, tightening the entire car cover 2 and enclosing it.

[0005] The utility model is manufactured in the form of a patch and then sewn on a car cover, and has the characteristics of precise manufacturing process, positive and negative double-force pulling, balanced force, and significant car cover tightness effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Embodiment 1: This embodiment consists of a base sheet 1, a tightening device, a car cover 2, and a car cover hem 3. The base sheet 1 is a long sheet of material, either cotton yarn or chemical fiber, which can be sewn, hot pressed, or heat-sealed. A retention point 4 is set horizontally in the middle of the base sheet 1, which is the starting point for the left hook rib 5 and the right hook rib 6. The left hook rib 5 and the right hook rib 6 are opposite to each other. To the left of the retention point 4, in front of the base sheet 1 facing the left hook rib 5, at least one left retention ring 7 is formed. The left hook rib 5 can be hooked into it. The distance between the retention point 4 and the left retention ring 7 is limited to allow the left hook rib 5 to have sufficient elastic expansion space. To the right of the retention point 4, in front of the base sheet 1 facing the right hook rib 6, at least one right retention ring 8 is formed. The right hook rib 6 can be hooked into it. The distance between the retention point 4 and the left retention ring 7 is limited to allow the right hook tie 6 to have sufficient elastic expansion and contraction space. When the left hook tie 5 hooks onto the left retention ring 7, the base sheet 1 contracts rightward from the retention point 4 due to the elastic force, that is, the distance between the retention point 4 and the left retention ring 7 is shortened. After the base sheet 1 is sewn onto the garment 2, it causes the garment hem 3 to contract inward, i.e., to the right, thereby tightening the garment 2. When the right hook tie 6 hooks onto the right retention ring 8, the base sheet 1 contracts leftward from the retention point 4 due to the elastic force, that is, the distance between the retention point 4 and the right retention ring 8 is shortened. After the base sheet 1 is sewn onto the garment 2, it causes the garment hem 3 to contract inward, i.e., to the left, thereby tightening the garment 2. When the left and right belt hooks 5 and 6 simultaneously hook onto the left and right retaining rings 7 and 8, the hem 2 of the garment, located on the left and right sides of the vehicle body and between the front and rear wheels, simultaneously contracts toward the center, tightening the entire garment 2 and encircling it. At this point, the left belt hook 5, left retaining ring 7, and retaining force point 4, as well as the right belt hook 6, right retaining ring 8, and retaining force point 4, are simultaneously taut and aligned. Thus, a tightening device is formed, comprising the base plate 1, the garment hem 3, the center retaining force point 4, the left and right belt hooks 5 and 6, and the left and right retaining rings 7 and 8.

[0011] Example 2: This example is basically the same as Example 1, except that the functions of the left belt hook ties 5 and the right belt hook ties 6 are replaced by a section of left buckle 9 and a section of right buckle 10, respectively. A section of left buckle 9 and a section of right buckle 10 are respectively provided with one or more left buttonholes 11 and right buttonholes 12. The fixing force point 4 is still a point tube 2 used to fix the starting ends of a section of left buckle 9 and a section of right buckle 10 in opposite pulling directions; at the same time, the functions of the left fixing pull ring 7 and the right fixing pull ring 8 are replaced by one or more left buttons 13 and right buttons 14 arranged in a row. The left buttonhole 11 is fastened with the left button 13, and the right buttonhole 12 is fastened with the right button 14, so that the hem 2 of the garment can be fastened. At this point, a tightening device consisting of the base plate 1, the hem of the garment 3, the middle fixing force point 4, the left and right buckle belts 9 and 10, the left and right buttonholes 11 and 12, the left button 13 and the right button 14 is formed.

[0012] Example 3: This example is essentially the same as Example 1, except that the functions of the left and right hook ties 5 and 6 are replaced by a section of left convex self-adhesive tape 15 and a section of right convex self-adhesive tape 16, respectively. The retention point 4 instead simultaneously secures the opposite starting ends of the sections of left convex self-adhesive tape 15 and right convex self-adhesive tape 16. Simultaneously, the functions of the left and right retention rings 7 and 8 are replaced by a section of left concave self-adhesive tape 17 and a section of right concave self-adhesive tape 18. The sections of left convex self-adhesive tape 15 and left concave self-adhesive tape 17 adhere to each other, while the sections of right convex self-adhesive tape 16 and right concave self-adhesive tape 18 adhere to each other, thereby tightening the hem 3 of the garment. This completes a tightening device consisting of the base sheet 1, the garment hem 3, the intermediate retention point 4, the left convex self-adhesive tape 15 and right convex self-adhesive tape 16, and the left concave self-adhesive tape 17 and right concave self-adhesive tape 18.

[0013] Example 4: This example is essentially the same as Example 1, except that the functions of the left and right hook tension bars 5 and 6 are replaced by a section of a left and right hook tension spring 19 and a section of a right hook tension spring 20, respectively. The retention force point 4 remains a single point, securing the starting ends of the sections of the left and right hook tension springs 19 and 20, which are in opposite directions of tension. Meanwhile, the functions and positions of the left and right retention rings 7 and 8 remain unchanged. When the sections of the left and right hook tension springs 19 and 20 respectively hook the left and right retention rings 7 and 8, the garment hem 3 can be tightened. Thus, a tightening device is formed, comprising the base plate 1, the garment hem 3, the intermediate retention force point 4, the left and right hook tension springs 19 and 20, and the left and right retention rings 7 and 8.
