Description

  This invention relates to a metal head for safety shoes. In particular, it refers to a metal head dedicated to safety shoes.

  There is a provision to forcibly wear safety shoes in order to avoid injuries caused by pressure on the toes of workers when heavy objects fall in places such as general factories or construction sites. Current safety shoes can be subjected to external impacts by providing a single steel head or plastic steel head mainly on the shoe head. Among them, the steel head can withstand more impact, but the overall weight is heavier. Also, the weight of the plastic steel head is lighter, but the strength of the pressure resistance is not good.

  The structure of the conventional steel head shown in FIGS. 1 and 2 includes an outer peripheral side plate having a U-shaped arc shape in which one front portion is narrow and the rear portion is wide. A top plate is jointly extended from the top end of the outer peripheral side plate to the inside, and a bottom edge plate is extended from the bottom end to the inside, so one arch type is formed at the rear end of the steel head. By forming the opening, a space for the toes is formed.

  The steel head described above is integrally formed with a press using a steel plate, and the outer peripheral side plate, the top plate and the bottom edge plate all have the same thickness. Since the overall thickness size cannot be reduced to take into account the strength of the pressure resistance of the top plate, the weight of the steel head is very heavy, which affects the comfort when walking.

  In particular, when a heavy object falls and hits the shoe head, the steel head receives the impact force mainly on the top plate, and then transmits it to the shoe bottom through the outer side plate and the bottom edge plate. Since there is no special reinforcing structure on the top plate and the bottom edge plate that are most likely to collapse or deform, the pressure resistance effect is affected, so further improvement is necessary.

  The object of the present invention is to provide a metal head for safety shoes. It can effectively increase the strength of pressure resistance without changing the original width size and mold of the metal head, and can achieve a lightweight mold structure by using aluminum or aluminum alloy material, so it can be used in industrial It has value.

Since the thickness of the top plate increases gradually from the outer plate to the top plate, the strength of the pressure resistance of the metal head is increased and the original width size and type of the metal head are not affected by it. In addition, a lightweight structure can be achieved using aluminum or aluminum alloy material.

  In the better embodiment, the bottom arc part is connected between the outer peripheral side plate and the bottom edge plate, and the thickness of the bottom arc part gradually increases from the outer side plate toward the bottom edge plate. Since the thickness of the edge plate at the bottom is thicker than that of the outer peripheral side plate, the strength of the pressure resistance can be increased.
