Description

Technical Field

[0001] This utility model relates to the field of pet harness technology, and in particular to a pet harness with an improved head strap structure. Background Technology

[0002] A pet harness is a piece of clothing worn by pets to control and manage their behavior. It wraps around the pet's chest and back, connecting to a leash to help owners better control their pets, especially preventing sudden lunges or runs during walks. Existing pet harnesses are typically made of nylon rope. Nylon rope is relatively stiff, lacks flexibility, and offers little cushioning. When a pet suddenly lunges or runs, the resulting reaction force can cause strangulation injuries and skin abrasions, potentially leading to localized skin ulcers with prolonged use. To prevent this, a strap is incorporated inside the nylon rope, allowing for contact with the pet and increasing cushioning and softness, reducing friction. Traditional harnesses typically consist of a foam pad and a fabric covering the foam pad. When the fabric wraps around the ends of the foam pad, it... Figure 1 As shown, the bag needs to be folded to one side to wrap the sponge pad first, and then the left and right sides of the bag are folded inward to complete the wrapping. This results in gaps at the ends of the straps. When exercising outdoors, small stones and other impurities and dirt can easily get trapped in these gaps and are difficult to clean. In addition, the ends of the sponge pad must be flat. If a curved end is used, air pockets will appear when wrapping, resulting in poor aesthetics. Therefore, it is necessary to improve this method.

[0039] The following are merely preferred embodiments of the present invention and do not limit the scope of protection of the present invention.

[0040] An improved head-support structure pet harness, consisting of multiple harness straps 1 connected together, such as... Figures 2 to 5 As shown, the harness 1 includes a sponge pad 11 and a covering strap 12. The covering strap 12 wraps around the four surfaces of the sponge pad 11. Two sides of the covering strap 12 are spliced ​​to one of the surfaces of the sponge pad 11, forming a seam 125 on that surface. The surface of the harness 1 with the seam 125 is the seam surface. The covering strap 12 has an extension 124 protruding from the outer end of the sponge pad 11. The extension 124 is folded toward the seam surface and wraps around the outer end of the sponge pad 11 to form a wrapping portion 121. The covering strap 12, the wrapping portion 121, and the sponge pad 11 are sewn together. The inner layer of the extension 124 is folded back and pressed onto the surface of the outer end of the seam surface. The outer layer of the extension 124 covers the outer end face of the outer end of the sponge pad 11 and is folded over and pressed onto the inner layer of the extension 124. Traditional pet harnesses have poor cushioning, such as... Figure 1 As shown, while some carrier straps 1 that increase cushioning through built-in sponge often have gaps 14 after the ends of the traditional carrier strap 1 are wrapped, dirt and grime can easily accumulate in the gaps 14 during outdoor pet activities, making them difficult to clean. Furthermore, the ends of the carrier strap 1 can only be flat; if an arc-shaped end face is used, it will create air pockets, resulting in poor aesthetics. In contrast, this utility model uses a wrapping part 121 to wrap the ends of the sponge pad 11, preventing gaps 14 from appearing at the ends of the carrier strap 1 and avoiding impurities from entering the gaps 14, ensuring cleanliness and hygiene, and facilitating cleaning. The wrapping part 121 is folded towards the center, so that the wrapping part 121 fits tightly against the end face of the sponge pad 11, preventing air pockets. It can adapt to both flat and arc-shaped end faces of the sponge pad 11, improving aesthetics.

[0041] Specifically, a first adhesive layer 122 is provided on the contact surfaces of the sponge pad 11 and the covering tape 12, or the first adhesive layer 122 is provided on either the contact surface of the sponge pad 11 or the covering tape 12. The sponge pad 11 and the covering tape 12 are glued and fixed together by the first adhesive layer 122. The sponge pad 11 and the covering tape 12 are not only connected and fixed by sewing, but also glued and fixed together by the first adhesive layer 122, which further improves the connection strength, prevents gaps from forming between the sponge pad 11 and the covering tape 12, and ensures that the covering tape 12 always adheres to the sponge pad 11.

[0042] Specifically, a reinforcing strip 13 is sewn to the outer surface of the covering strip 12, and the reinforcing strip 13 covers the splice seam 125. By covering and shielding the wrapped part 121 with the reinforcing strip 13, not only is the structural strength improved, but the wrapped part 121 is also further secured, improving the protection of the wrapped part 121. The reinforcing strip 13 is directly sewn onto the sponge pad 11 through a sewing process to further improve the connection strength and increase reliability and stability. The reinforcing strip 13 is made of nylon.

[0043] Specifically, the reinforcing strip 13 extends along the length of the back strap 1 and covers the seam 125. The reinforcing strip 13 completely covers the seam 125, thereby hiding the seam 125, improving aesthetics, and also preventing impurities from entering the seam 125, preventing the fabric strap 12 from separating from the sponge pad 11 due to pulling, thus improving reliability and stability.

[0044] Specifically, a rounded chamfer is provided on the left and right sides of the outer end of the sponge pad 11. The wrapping part 121 wraps tightly around the rounded chamfer, and the outer end of the strap 1 forms a fully enclosed head with no gaps on the outer end face and sides. The corners are not right angles. The rounded chamfer avoids right angles at the end of the strap 1, thereby preventing sharp right angles from scratching the pet and improving wearing comfort.

[0045] Specifically, the outer end of the sponge pad 11 is semi-circular, and the wrapping part 121 wraps tightly around the outer end of the sponge pad 11. The outer edge of the wrapping part 121 is folded towards the center to form a fan-shaped wrapping part 121. The outer end of the carrying strap 1 forms a fully enclosed, semi-circular, round head with no gaps on the outer end face and sides. The outer end of the sponge pad 11 is semi-circular to increase the end curvature, further preventing the sharp edges of the carrying strap 1 from scratching the pet and improving wearing comfort. The outer edges of the wrapping part 121 are all folded towards the center, so that they can fit tightly against the end face of the sponge pad 11 and avoid air pockets.

[0046] Specifically, the left and right sides of the sponge pad 11 are folded and spliced ​​towards the seam surface to form a double-layer structure. A second adhesive layer 123 is provided on the inner surface of the sponge pad 11. During production, adhesive is applied to the outer surface of the sponge pad 11 or the inner surface of the covering strap 12 to form a first adhesive layer 122. Then, the outer surface of the sponge pad 11 is glued to the inner surface of the covering strap 12. Next, adhesive is applied to the inner surface of the sponge pad 11 to form a second adhesive layer 123. Finally, the sponge pad 11 is folded to form a double-layer structure, increasing the thickness of the sponge pad 11, improving cushioning performance, and increasing the comfort of the pet. The seam of the folded sponge pad 11 is aligned with the splicing seam 125. The seam of the folded sponge pad 11 increases its bending ability, preventing excessive bending and breakage, and also increases its softness, further improving wearing comfort.

[0047] Specifically, such as Figure 6 and Figure 7 As shown, the pet harness also includes a first T-strap, a second T-strap, and two neck straps 4. The two ends of the first T-strap are connected to the two ends of the second T-strap via connecting buckles. One end of each neck strap 4 is connected to the middle of the first T-strap, and the other end is connected to the middle of the second T-strap. The two neck straps 4 form a neck opening 41. The inner sides of the first T-strap, second T-strap, and two neck straps 4 are all equipped with shoulder straps 1. When wearing the harness, first, the pet's head is passed through the neck opening 41 to place the harness around the pet's neck. Then, the first T-strap is fitted against the pet's back, and the second T-strap is fitted against the pet's chest. Finally, the connecting buckles are engaged to connect the first and second T-straps, completing the harness quickly and easily. The first T-strap, second T-strap, and two neck straps 4 are all made of nylon, and together with the shoulder straps 1, they provide cushioning, increasing structural strength and shock absorption. The structure is simple, low-cost, lightweight, easy to carry, and highly comfortable to wear.

[0048] Specifically, the first T-shaped strap includes a first horizontal strap 21 and a first vertical strap 22. The first end of the first vertical strap 22 is connected to the middle of the first horizontal strap 21, and the second end of the first vertical strap 22 is connected to two neck straps 4. The second T-shaped strap includes a second horizontal strap 31 and a second vertical strap 32. The first end of the second vertical strap 32 is connected to the middle of the second horizontal strap 31, and the first end of the second vertical strap 32 is connected to two neck straps 4. A back strap 1 is provided on the inner surface of the first horizontal strap 21, the first vertical strap 22, the second horizontal strap 31, and the second vertical strap 32 for connection. The buckle includes a female socket 51 and a male plug 52. A female socket 51 is provided at each end of the first horizontal strap 21, and a male plug 52 is provided at each end of the second horizontal strap 31. Each female socket 51 is connected to the corresponding male plug 52 by a snap fastener. A triangular ring 6 is provided at the second end of the second vertical strap 32 and the second end of the first vertical strap 22. The two ends of the two neck straps 4 are connected to the two triangular rings 6 respectively. The two back straps 1 located on the inner side of the two neck straps 4 are fixedly connected to the back straps 1 located on the inner side of the second vertical strap 32.

[0049] The first horizontal strap 21 and the second horizontal strap 31 are connected by two connecting buckles to encircle and secure the pet's chest and back. Two neck straps 4 are connected to the first horizontal strap 21 and the second horizontal strap 31 by the first vertical strap 22 and the second vertical strap 32 respectively, forming an integrated pet harness. The first vertical straps 22 and the second vertical straps 32 not only serve a connecting function but also increase the contact area with the pet, reducing pressure on the pet during pulling and improving wearing comfort. The triangular ring 6 connects the neck straps 4 so that the two neck straps 4 initially form a neck opening 41, preventing the two neck straps 4 from closing side-by-side at the neck opening 41, thus preventing the pet's neck from being clamped and suffocated during normal activity, improving safety.

[0050] Specifically, the length of the second horizontal strap 31 is greater than the length of the first horizontal strap 21. The second horizontal strap 31 is provided with two first adjusting buckles 33, both of which are located adjacent to the male plug 52. The two neck straps 4 are each provided with a second adjusting buckle 42. The two ends of the back strap 1 located on the inner side of the second vertical strap 32 are respectively provided with first elastic loops 34, and the second vertical strap 32 passes through the two first elastic loops 34. The two ends of the two back straps 1 located on the inner side of the two neck straps 4 are respectively provided with second elastic loops 43, and the two neck straps 4 pass through the corresponding two second elastic loops 43. The second adjusting buckle 42 is located between the two second elastic loops 43, and the first adjusting buckle 33 is located between the first elastic loop 34 and the male plug 52. The first horizontal strap 21 is provided with a handle 23, the first end of the first vertical strap 22 is provided with a traction connecting ring 24, and the middle of the first vertical strap 22 is provided with an identification plate 25.

[0051] The length of the second horizontal strap 31 is adjusted using two first adjustment buckles 33 to accommodate pets with different chest circumferences; the lengths of the two neck straps 4 are adjusted using two second adjustment buckles 42 to accommodate pets with different neck thicknesses, thereby increasing applicability and flexibility. The second horizontal strap 31 is secured by a first elastic loop 34 to prevent it from unraveling after shortening and to limit the first adjustment buckles 33, preventing over-adjustment; the neck strap 4 is secured by a second elastic loop 43 to prevent it from unraveling after shortening and to limit the second adjustment buckles 42, preventing over-adjustment. A handle 23 allows the owner to easily lift the pet, especially for quick control when taming the pet; a leash connection ring 24 facilitates connecting the leash outdoors and easily disassembling the leash indoors, improving usability; and a label 25 displays the brand logo or pet information, enhancing brand recognition or pet identification.
