Waistband

Abstract

A waistband comprises a buckle head (1) of a traditional waistband and a waistband body (2) of the traditional waistband, and two ends of an adjusting device (4) can be connected with the waistband body (2) through a connecting device (3). The structure of the adjusting device (4) is that the theoretical lengths of the upper side and the lower side of the adjusting device (4) are changed through pulling force of the two ends of the adjusting device (4) in the continuously-changing direction of the belt body (2), and when different postures such as standing, sitting, squatting and the like of a human body are changed, under traction of waistbands on the two sides of the rear waist part and a trouser belt on the rear waist part of trousers, the trouser body can be adjusted. The belt body of the belt at the back waist part bears forces with three changing directions and changing magnitudes, and due to the structure and the material of a common belt, especially when a person sits and squats, the belt body at the back waist part of the person has the phenomenon that the upper side is too long and the lower side is too short, bulges are formed, and the privacy of the back waist of the person is exposed; the adjusting device (4) solves the problem by changing the lengths of the upper side and the lower side of the device. The waistband has the advantages that the waistband can be always close to the body in the process of continuously changing the body position, the privacy in the back waist is not exposed, the waistband is a good ornament, the wearing is attractive, and the personal charm is greatly improved. The device is novel and practical.

Description

Technical Field

[0001] The invention relates to clothing accessories and belongs to the fields of clothing design and luxury goods, and in particular to a new concept belt that prevents privacy exposure and is both beautiful and practical. Background Art

[0002] There's a phenomenon in daily life where, when someone squats, their lower back reveals their private parts, causing embarrassment for both parties. Analysis of this phenomenon reveals two main reasons: First, the pants don't fit well, with too little crotch space. When squatting, the pants' size below the lower back is limited, failing to perfectly fit the body's curves. This causes the belt to pull on the lower back, deforming and exposing private parts. While high-end, custom-made pants can solve this problem, they're not suitable for most ordinary consumers. Second, there's a problem with the waistband. When sitting, standing, squatting, and other different postures, the belt pulls on the waistband, causing it to deform. Because the waistband has a certain width and toughness, it can only adapt to changes in shape through local deformation. Summary of the Invention

[0003] The present invention mainly solves the problem of waist belts encountered by most ordinary people.

[0004] Traditional belts on the market usually consist of two parts: a buckle and a belt body. The belt body is usually made of a single piece of leather, cloth, or other materials, and is in the form of a long strip. After long-term use, we will find that the belt has deformed. The belt at the back of the waist is deformed downward, and the belt on both sides of the back of the waist is obviously tilted upward. This once again shows that the belt is subjected to different forces in different body positions. When sitting or squatting, the back of the pants exerts too much force on the belt, causing the upper part of the middle of the waist to be too long and the lower part to be too short. Due to the toughness and non-plasticity of the belt material, deformation occurs, resulting in the private part of the waist being exposed when sitting or squatting, which is embarrassing. To address the above problems, I have proposed a new belt concept after research that can perfectly fit the different postures of the human body.

[0005] We know that a straight line has no width, but any entity has width. As long as a force is applied in a direction different from that of the straight line, the object will deform. The effect of the deformation is related to the width of the object. Therefore, reducing the width of the belt can appropriately solve some problems. Even in different body positions, the belt body will only undergo slight deformation, and the belt will not be too long on the upper side of the waist and too short on the lower side, resulting in an embarrassing picture. However, women's belts are generally narrower, and men generally cannot accept narrow belts. Therefore, without changing the width of the belt, the only change can be made to the belt at the back waist. By narrowing the belt at the back waist, the effect of a narrow belt can be achieved.

[0006] We analyzed the forces acting on the waistband based on different human postures, such as standing, sitting, and squatting. The direction of the forces acting on both sides of the waistband in the middle of the back waistband changes from linear forces to upward forces due to the process of the human body moving from standing to squatting, coupled with the constraint of the trouser belt at the back waistband. These forces, combined with the downward force exerted on the waistband by the trouser belt at the back waistband, form a triangular shape, causing the waistband to also change into a triangular shape. The waistband at the back waistband is deformed due to the forces. Due to the inelasticity and toughness of the material, this part of the waistband becomes longer on the upper side and shorter on the lower side. This manifests itself as a bulge in the waistband at the back waistband, exposing the privacy inside the belt and causing an embarrassing situation. Therefore, by adding an adjustment device in the middle of the waistband at the back waistband, the direction of the forces acting on the waistband at the back waistband changes, causing the upper side of the middle structure of the back waistband to contract and the lower side to extend, just like the bending effect of a fishbone under force. This prevents the waistband from deforming when the human body sits or squats, and allows the trousers at the back waistband to fit the human body better, avoiding the embarrassing exposure.

[0007] Based on the above, a device is designed whose deformation due to force is negligible and only changes the theoretical length of the upper and lower sides, such as Figure 1 The adjusting device (4) relies on the traction of the waistband on both sides of the back waist and the trouser belt on the back waist to change the force direction and force magnitude when the human body changes to different postures such as standing, sitting, squatting, etc., so as to produce the effect of contraction of the upper side of the waistband and extension of the lower side of the waistband at the back waist. This adjusting device (4) is not limited to a specific fishbone shape. The underlying principle is to change the theoretical length of the upper and lower sides of the waistband, so that the waistband of the trousers at the back waist can better fit the body without being exposed. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 It is a structural schematic diagram of the present invention.

Claims

1. A waist belt comprising: a conventional waist belt buckle (1) and a conventional waist belt body (2), wherein both ends of an adjusting device (4) can be connected to the waist belt body (2) via a connecting device (3). The adjusting device (4) is constructed such that the theoretical lengths of the upper and lower sides of the adjusting device (4) are changed by the constantly changing direction of the pulling force of the waist belt body (2) on both ends of the adjusting device (4). The waist belt is a device based on the underlying principle that the upper side of the waist belt device (4) contracts and the lower side extends by changing the direction and magnitude of the force when the human body is standing, sitting, squatting, etc.
