Description

Heavy-duty auxiliary handle Technical Field

[0001] This disclosure relates to the field of auxiliary handles for carrying heavy objects, and more particularly to an auxiliary handle for carrying an object of considerable weight. Prior Technology

[0002] Lifting heavy objects by hand is a common activity in daily life, shopping, laboratory work, or industrial handling. Many designs for carrying heavy objects, such as narrow handles on plastic shopping bags or tote bags, ropes, or handles on heavy containers, present a serious problem.

[0003] The problem lies in the concentrated pressure and hand injuries caused by traditional narrow carrying straps. This concentrates the weight of the object on the small contact surface between the user's fingers and palm. When the weight is heavy and the contact surface is very small, the resulting pressure can cause marks, pain, and poor blood circulation in the hands. Long-term or frequent use can also lead to tendon and ligament damage.

[0004] In addition, comfort and safety are insufficient, and the carrying straps are prone to twisting or slipping, affecting the stability of the hand grip and increasing the difficulty of carrying and moving.

[0005] In view of the shortcomings of the traditional handling and moving of heavy objects, an improved structure is provided to solve this problem. Summary of the Invention

[0006] To address the aforementioned issues, this disclosure provides a simple and ergonomic auxiliary handle for carrying heavy objects. By increasing the effective force-bearing area of ​​the palm through the support body and enhancing grip stability through the grip groove design, pressure is distributed, hand fatigue and pain are reduced, fundamentally improving the comfort and safety of carrying heavy objects.

[0007] In one embodiment of this disclosure, a heavy-duty auxiliary handle is provided, comprising: a support body having a grip groove; and at least one hook disposed on the support body, the hook having an upward-facing open opening, and the grip groove being disposed on the side of the support body away from the opening.

[0008] The beneficial effect of this invention lies in its ergonomic cylindrical support body and wave-shaped grip groove design, which effectively expands the contact area with the user's palm and provides stable grip support. Users can simply hang the bag's handles on the hooks at both ends of the support body to distribute the high pressure originally concentrated on the narrow handles to the entire palm, thereby greatly improving the comfort and efficiency of carrying heavy objects. This is suitable for various scenarios such as daily life, shopping, and laboratory handling. Simple Explanation of the Diagram
