Abstract
Description
Technical Field
[0001] This utility model relates to the field of shapewear technology, and particularly to shapewear pants. Background Technology
[0002] Traditional shapewear often uses a single elastic fabric for overall wrapping design. While it can achieve basic shaping function, it has significant limitations: (1) Excessive compression or insufficient support in the buttock area, failing to balance shaping and freedom of movement, easily leading to flattened buttocks; (2) The waist and legs rely on uniform elastic pressure, which can easily lead to poor blood circulation and rolled-up edges with long-term wear; (3) The conflict between privacy protection and breathability, with the stretching state causing skin penetration and poor heat dissipation; (4) Insufficient antibacterial properties in the crotch area, making it easy for bacteria to grow. Existing improvement solutions mostly enhance support by locally thickening or sewing on rigid bone strips, but this sacrifices dynamic fit and comfort, making it difficult to adapt to diverse body shape needs. In addition, many buttock-lifting pants on the market do not have enough capacity in the buttocks area. Sometimes, when the buttocks are lifted, the insufficient capacity can flatten the buttocks, resulting in an unsightly appearance and discomfort. Utility Model Content
[0003] To address the above issues, this invention provides a shapewear that is adaptable to women with different hip sizes, offering both comfort and privacy protection.
[0004] This utility model discloses a shaping pant, including a front panel, a back panel, and pant legs. The front and back panels are connected on opposite sides. The lower side of the front panel is connected to the upper end of the front piece of the pant leg, and the lower side of the back panel is connected to the upper end of the back piece of the pant leg. The back panel is provided with a hip expansion area and a vertical elastic spine. The elastic spine extends vertically along the center of the hip expansion area, and its two ends are respectively connected to the upper and lower ends of the back panel. The hip expansion area has a double-layer structure, including an inner layer and an outer layer. The inner layer is composed of a symmetrically arranged left skin-contact layer and a right skin-contact layer. The left skin-contact layer is connected to the left side of the hip expansion area and the elastic spine on both sides, and the right skin-contact layer is connected to the right side of the hip expansion area and the elastic spine on both sides. The lower side of the left skin-contact layer is connected to the lower side of the hip expansion area. A fabric-free left cutout area is formed between the sides, and a fabric-free right cutout area is formed between the lower side of the right skin-adhesive layer and the lower side of the buttock expansion area; a left opening is formed between the upper side of the left skin-adhesive layer and the upper side of the buttock expansion area, and a right opening is formed between the upper side of the right skin-adhesive layer and the upper side of the buttock expansion area; the outer layer completely covers the inner layer, the left cutout area, and the right cutout area, and the area of the outer layer is larger than that of the inner layer; a left strip-shaped gap and a right strip-shaped gap are formed between the upper side of the outer layer and the upper side of the buttock expansion area, the left strip-shaped gap communicating with the left opening, and the right strip-shaped gap communicating with the right opening; the left opening, the right opening, and the left and right strip-shaped gaps together constitute an elastic expansion structure, while achieving privacy protection through the outer layer coverage and gap layout.
[0005] Preferably, the outer contour of the buttock expansion area is apple-shaped, and the left and right strip-shaped gaps formed between the upper side of the outer layer and the upper side of the buttock expansion area extend along the curve of the buttock.
[0006] Preferably, a buttock-lifting band is provided below the buttock expansion area. The two ends of the buttock-lifting band extend upward and partially surround the buttock expansion area. The ends of the buttock-lifting band are fixed to the corresponding sewing lines on the front and back panels.
[0007] Preferably, it also includes a waist belt, which is located at the waist of the human body and its lower side is connected to the upper side of the front and back panels. The waist belt has multiple vertical lumbar ribs to prevent the waist belt from curling up.
[0008] Preferably, the inner side of the trouser leg is provided with a leg-tightening structure, which is an elastic pressure band that extends longitudinally along the inner side of the trouser leg.
[0009] Preferably, the fabric-free areas of the left and right hollowed-out zones are arc-shaped gaps, the boundaries of which are formed by the left skin-adhesive layer, the right skin-adhesive layer, the elastic spine, and the back panel.
[0010] Preferably, the front panel includes a tucked-in abdomen, with one side of the tucked-in abdomen connected to a side region on each side, and the side region connected to the rear panel located behind the body on the opposite side.
[0011] Preferably, the crotch area between the lower sides of the front and rear panels is made of antibacterial fabric.
[0012] The shaping pants that implement this utility model have the following beneficial technical effects:
[0013] Through the synergistic effect of the elastic spine band and the double-layer expansion structure, the longitudinal constraint of the spine band provides directional rebound force, and the left / right skin-contact layers extend to the sides when subjected to hip pressure. Combined with the deformation space of the hollowed-out area, it achieves adaptive adjustment of hip volume. The strip-shaped slit layout of the outer layer forms multiple folds when stretched, and the overlapping fabric covers the hollowed-out area, dynamically balancing the expansion needs and privacy protection. The apple-shaped outer contour matches the direction of the gluteus maximus muscle, and the hip-lifting belt applies pressure from the bottom of the buttocks upwards, forming a "lifting-wrapping" dual mechanical path to increase the height of the hip peak; the waist belt is vertically anchored to the lumbar vertebrae to prevent force shift and ensure even distribution of pressure on the waist.
