Description

Technical Field

[0001] The invention relates to the technical field of safety shoes, in particular to a protective toe cap for safety shoes. Background Art

[0002] Safety shoes are described in the national standard GB 21148-2020, "Foot Protection - Safety Shoes," as "shoes that protect the wearer from injuries caused by accidents, have protective features, and ensure safety in the work area." Safety shoes generally protect the toes through a toe cap installed inside the shoe to protect the wearer's toes from impact and crushing injuries caused by heavy objects. The national standard GB 21148-2020, "Foot Protection - Safety Shoes," stipulates that "the toe cap should have an edge covering extending at least 5 mm below the rear edge of the toe cap and at least 10 mm in the opposite direction." This edge covering is called a "welt" and is generally made of soft plastic.

[0003] The design of the protective toe cap of safety shoes needs to be able to support the upper. However, when the protective toe cap does not have a soft welt to support the upper, the upper will arch outward and become uneven as a whole. In addition, the upper portion at the interface between the protective toe cap and the shoe last will bend and deform, especially when the shoe body is bent at a large angle. For example, when people run forward, their toes touch the ground and their heels lift up. At this time, the upper portion at the interface between the toe cap and the shoe last bends at an obtuse angle to the toe cap, which has a significant impact on the service life of the shoe body.

[0004] Currently, the toe guards of safety shoes are made of metal or non-metallic materials (such as glass fiber, plastic, carbon fiber, etc.), and then a soft plastic welt is made through another processing flow. Finally, the soft plastic welt is fixed to the bottom of the rear edge of the toe guard with an adhesive to form a safety toe guard with a welt. This type of safety shoe toe guard has many production steps, and workers need to manually use adhesive to adhere the welt to the bottom of the rear edge of the toe guard, or use an injection molding machine to press the welt under the rear edge of the toe guard to form the safety toe guard with a welt. The existing technology has many steps, low production efficiency, high equipment and labor costs, and a high defective rate due to manual operation. Summary of the Invention

[0005] In view of the defects of the prior art, the purpose of the present invention is to provide a protective toe cap for safety shoes.

[0006] The technical solution of the present invention is:

[0007] The present invention provides a protective toe cap for safety shoes, the protective toe cap comprising a toe cap body and an edge condition, the toe cap body being a bowl-shaped shell with an open end, the open end of the toe cap body being injection molded with the edge condition extending away from the open end, the edge condition being a double-layered welt;

[0008] The first layer of the along condition is an outer edge strip extending along the outer surface of the baotou body, and the second layer of the along condition is an inner edge strip extending along the inner surface of the baotou body, with a gap between the outer edge strip and the inner edge strip;

[0009] The outer edge strip includes a first end connected to the open end of the toe cap body and a second end opposite to the first end, wherein the thickness of the first end is greater than the thickness of the second end;

[0010] The end surface of the second end has a wave buffer edge;

[0011] The inner edge strip includes a third end connected to the open end of the toe cap body and a fourth end opposite to the third end, wherein the thickness of the third end is greater than the thickness of the fourth end;

[0012] The end surface of the fourth end has a wave buffer edge.

[0013] Furthermore, the outer surface of the outer edge strip and the outer surface of the protective toe cap are located on the same curved surface.

[0014] Furthermore, the inner surface of the inner edge strip and the inner surface of the protective toe cap are located on the same curved surface.

[0015] Furthermore, the thickness of the outer edge strip decreases gradually from the first end to the second end.

[0016] Furthermore, the thickness of the inner edge strip decreases gradually from the third end to the fourth end.

[0017] Furthermore, the toe cap body is a PC alloy toe cap body.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The protective toe cap for safety shoes provided by the present invention has a double-layer welt, comprising an outer welt and an inner welt. A gap exists between the outer and inner welts, providing a cushioning effect that significantly reduces the impact of undesirable bending of the upper on the shoe body. When the outer welt is combined with the upper, the upper will not arch outward; when combined with the shoe last, the inner welt provides a smoother transition. Each layer of the double-layer welt is very thin, providing a more comfortable contact with the foot and a smoother transition. A single welt, being too thick, would not fully utilize the material's flexibility. The provision of a wave-shaped cushioning edge significantly reduces the impact of undesirable bending of the upper on the shoe body.

[0020] 2. In the protective toe cap for safety shoes provided by the present invention, the outer edge strip includes a first end connected to the open end of the toe cap body and a second end opposite to the first end. The thickness of the first end is greater than the thickness of the second end. By setting the thickness of the first end to be greater than the thickness of the second end, a smooth transition effect can be achieved, thereby avoiding the phenomenon of the shoe upper arching outward.

[0021] 3. In the protective toe cap for safety shoes provided by the present invention, the inner edge strip includes a third end connected to the open end of the toe cap body and a fourth end opposite to the third end. The thickness of the third end is greater than the thickness of the fourth end. By setting the thickness of the third end to be greater than the thickness of the fourth end, the contact surface between the protective toe cap and the instep is flat and smooth, thereby improving wearing comfort.

[0022] 4. In the protective toe cap for safety shoes provided by the present invention, the end faces of the outer edge strip and the inner edge strip are provided with wave buffer edges. The provision of the wave buffer edges can enable the inner edge strip to maintain good flexibility when it is bent and gradually reduce stress concentration.

[0023] 5. The utility model adopts a one-time injection molding process to form a protective toe cap with a double-layer welt. Compared with the existing technology, it simplifies the manufacturing process, improves production efficiency, reduces equipment costs and labor costs, and significantly reduces the defective rate.
