Description

Technical Field

[0001] This invention relates to the field of diaper technology, specifically to a retractable waist Velcro for diapers. Background Technology

[0002] Pet diapers are a type of diaper specially designed for pets. They are mainly used for controlling dogs' urination and defecation, preventing dogs from defecating or urinating indiscriminately, and also making it easier to manage the heat cycle of female dogs.

[0003] Existing pet diapers often have a tight fit due to the varying thickness of fur that grows on a pet's body, reducing surface roughness. While elastic bands secure the diaper, they can become too tight. However, a pet's abdomen changes (e.g., after eating, the abdomen bulges), further stretching the already tight bands and causing discomfort. Therefore, the elastic band's tightness needs adjustment, ideally automatically. Furthermore, as urine accumulates, the diaper's weight increases. When the pet moves, the diaper may sag (moving backward or loosening), leading to a poor user experience and increasing the risk of it slipping off. Summary of the Invention

[0004] The present invention addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. It mainly provides a retractable waist Velcro for diapers to solve the technical problems mentioned in the background that pets have a poor experience when wearing diapers with a full belly, and that the diapers tend to fall off as they become heavier.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows:

[0006] A retractable waist Velcro for diapers includes a diaper body, wherein the diaper body is provided with an elastic band and Velcro for adapting the diaper body to be worn on pets of different sizes, the diaper body is provided with a retractable band for keeping the elastic structure in close contact with the pet's belly, and the elastic band is provided with a transmission mechanism for controlling the retraction of the retractable band.

[0007] Preferably, the diaper body has rings on both sides, and each ring has an elastic band.

[0008] Preferably, the telescopic belt is provided with an elastic band, and the elastic band is provided with Velcro, with the Velcro on both sides adhering to each other.

[0009] Preferably, the transmission mechanism includes a pull belt, which is disposed on an elastic belt, and a limiting ring is provided at the end of the elastic belt away from the pull belt.

[0010] Preferably, the telescopic belt is composed of multiple V-shapes, and multiple extension blocks are provided on the telescopic belt. Patches and connecting rods are provided between the multiple extension blocks, and the end of the pulling belt away from the elastic belt passes through the limiting ring and connects to the extension block.

[0011] Preferably, a tension ring is fitted onto the pull belt, the tension ring is disposed on both sides of the limiting ring, and a connecting strap is provided on the tension ring, the end of the connecting strap away from the tension ring being connected to the pet clothing.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: the diaper body is provided with elastic bands, and one end of the elastic bands is provided with Velcro. When the diaper body is worn on the dog, the Velcro on both sides is attached to each other by stretching the elastic bands on both sides. The elastic bands allow the diaper body to adapt to pets of different sizes, so that the diaper body will not be too big or too small and therefore not fit the pet.

[0013] When a pet's belly is full and bulging, the elastic band stretches. However, as the elastic band adapts to the growing belly, it can cause the pet's belly to feel constricted (because the elastic band stretches by elastic deformation to accommodate the pet's belly; the longer it stretches, the greater the force that constricts the dog's belly). But at this point, the stretched elastic band pulls the stretching blocks. Through the movement of multiple stretching blocks and patches, combined with the V-shaped design of the stretching band, the stretching blocks and patches unfold the V-shaped stretching band. As the stretching band unfolds, it replaces the stretching of the elastic band, causing the elastic band to partially contract until the elastic band and the stretching band reach a balance. This reduces some of the elastic band's elastic deformation, so as the pet's belly grows, the stretching doesn't rely solely on the elastic band, reducing the force exerted by the elastic band on the pet's belly and preventing severe constriction. This reduces discomfort when the pet's belly bulges. Furthermore, as the pet's belly shrinks, the elastic band and stretching band continuously contract, keeping the elastic band in close contact with the pet's belly. This also prevents the diaper from becoming loose as the pet's belly shrinks.

[0014] The pet clothing has a connecting strap. When the diaper becomes heavy and the pet runs, it may shift backward. At this time, the tightening ring will pull the strap forward, and the restraining ring will lock the strap. Because the strap is restrained, the elastic band and stretch band will not easily deform. This prevents the elastic band from stretching and expanding in the area that fits the pet's belly. As the elastic band of the diaper is worn in the front part of the pet's belly, and the belly gets larger as it moves backward, the elastic band in the belly part needs to expand before the diaper can move backward. Since the elastic band cannot expand easily at this time, and the connecting strap also helps to hold the diaper body in place, the diaper body is restrained from shifting backward when it becomes heavy, so it is unlikely to move or fall off.

[0015] The present invention will be explained in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0026] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be given below with reference to the accompanying drawings, which illustrate several embodiments of the present invention. However, the present invention can be implemented in different forms and is not limited to the embodiments described in the text. Rather, these embodiments are provided to make the disclosure of the present invention more thorough and complete.

[0027] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly associated with those skilled in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] Please refer to the appendix carefully. Figures 1-8 A retractable waist Velcro for diapers includes a diaper body 1, an elastic band 3 and Velcro 4 for adapting the diaper body 1 to be worn on pets of different sizes, a retractable band 5 for keeping the elastic structure in close contact with the pet's belly, and a transmission mechanism for controlling the retraction of the retractable band 5 on the elastic band 3.

[0030] The specific operating procedure of this invention is as follows: The diaper body 1 is put on the pet's buttocks, and then the two Velcro straps 4 are pulled outward until they stick together. The elastic band 3 is then fixed to the front part of the pet's belly. At this time, the diaper body 1 is worn on the pet. When the pet eats and its belly gets bigger, the bulging belly will push the elastic band 3 outward. At this time, the elastic bands 3 on both sides will be stretched first. The stretching of the elastic band 3 will drive the stretching band 5 to stretch through the transmission mechanism. As the stretching band 5 stretches, it replaces the elastic band 3, and the elastic band 3 begins to contract until the elastic band 3 and the stretching band 5 are in a balanced state. As the food in the pet's belly is digested, the pet's belly shrinks, and the elastic band 3 and the stretching band 5 will also contract as the pet's belly shrinks, keeping the elastic band 3 always attached to the dog's belly.

[0031] Please refer to Figures 1-3The diaper body 1 has rings 2 on both sides, each ring 2 has an elastic band 5, each elastic band 5 has an elastic band 3, and each elastic band 3 has a Velcro 4. The Velcro 4 on both sides are attached to each other.

[0032] When putting on the diaper body 1, the loops 2 on both sides wrap around the pet's belly. Then, pull the Velcro 4 on both sides outward. The Velcro 4 will pull the elastic band 3 to stretch until the Velcro 4 on both sides stick together. Then, the Velcro 4 stick together to put the diaper body 1 on the pet. Due to the setting of the elastic band 3, the elastic band 3 can stick to the pet's belly, so as to fix the diaper body 1 for pets of different sizes.

[0033] Please refer to Figures 2-7 The transmission mechanism includes a pull belt 9, which is mounted on an elastic belt 3. A limiting ring 10 is provided at the end of the elastic belt 3 away from the pull belt 9. The telescopic belt 5 is composed of multiple V-shapes. Multiple extension blocks 6 are provided on the telescopic belt 5. Patches 7 and connecting rods 8 are provided between the multiple extension blocks 6. The end of the pull belt 9 away from the elastic belt 3 passes through the limiting ring 10 and connects to the extension blocks 6.

[0034] When the elastic band 3 is stretched, the stretching of the elastic band 3 pulls the pulling band 9. The pulling band 9 is made of a material with a certain degree of hardness, such as rubber or plastic. The pulling band 9 pulls one of the extension blocks 6. One of the extension blocks 6, together with the patch 7 and the connecting rod 8, drives the entire set of extension blocks 6, patch 7 and connecting rod 8 to move. The patch 7 moves against the V-shaped inner wall of the telescopic band 5. The telescopic band 5 is made of composite cardboard. As the patch 7 moves continuously, it pushes the telescopic band 5 to continuously unfold, thus making the telescopic band 5 longer. As the telescopic band 5 becomes longer, the elastic band 3 contracts through its own elasticity to keep it in contact with the pet's belly. When the equilibrium point is reached, the elastic band 3 and the telescopic band 5 stop stretching, and the elastic band 3 is in a state of contact with the pet's belly. However, because the stretching of the elastic band 3 is replaced by the telescopic band 5, the elastic band 3 is not as constricting on the pet's belly.

[0035] Please refer to Figure 8 A tension ring 12 is fitted on the pull belt 9. The tension ring 12 is located on both sides of the limiting ring 10. A connecting belt 11 is provided on the tension ring 12. The end of the connecting belt 11 away from the tension ring 12 is connected to the pet clothing.

[0036] The connecting strap 11 is attached to the pet's clothing. When the diaper body 1 is changed and worn on the pet, the tension ring 12 at one end of the connecting strap 11 is attached to the pull strap 9, and the two tension rings 12 are located on both sides of the limiting ring 10. When the diaper body 1 moves backward, the tension ring 12, together with the limiting ring 10, pulls the pull strap 9 into a V-shape, thus preventing the pull strap 9 from moving further. This restricts the elastic band 3 and the stretch band 5. The pull strap 9 itself also helps to hold the diaper body 1 in place, preventing it from falling off due to increased weight. The connecting strap 11 is not a disposable item and will not be replaced with the diaper body 1. It can be used multiple times over a long period of time.

[0037] The present invention has been described by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
