Description

  The present invention relates to a shoe protector for protecting an instep and ensuring safety.

Conventionally, in order to protect the toe of the foot, a core made of steel plate or hard resin is attached to the toe part of the shoe, and this core protects the toe by receiving the fall of building materials, tools, etc. Safety shoes are known. In addition, safety shoes are also known in which such a core material is detachable so as to reduce the weight of the shoes when moving over a long distance. (See, for example, Patent Document 1)
JP 9-187304 A

  In the safety shoe described in Patent Document 1, a core material storage part is formed in the toe part, and the core material is taken in and out of the core material storage part as necessary. However, in order to protect the feet of visitors and inspectors during factory tours and inspections, etc., shoes such as normal leather shoes and sneakers worn by visitors and inspectors are replaced with safety shoes. It is necessary, and when changing shoes, it takes time to manage the shoes worn by visitors and inspectors, and it may be troublesome for visitors and inspectors to change shoes. obtain. Furthermore, since the lower edge of the core material is connected to the shoe sole, depending on the weight of the object that has fallen, the core material may be deformed and abut against the instep of the foot, causing the impact to occur. There is a defect that can be transmitted to the instep of the foot and possibly injure the foot.

  The object of the present invention is to solve the problems as described above.

  That is, the shoe protector according to the present invention includes an overshoe-like attachment member that is repeatedly worn while wearing footwear, and a protection member that is rigid and attached to the attachment member so as to cover at least the instep portion of the foot. And a bending portion formed by bending the protective member so as to follow at least the shape of the instep portion of the foot, and when the bending portion receives an impact, the bending portion is grounded to a grounding surface. And a leg portion that prohibits movement of the curved portion in the direction of the instep portion in a state of being separated from the instep portion, and the attachment member has a lower end of the leg portion except when the protective member receives an impact A holding means for holding the protective member at a position above the grounding surface is provided.

  Since such a shoe protector is designed to attach a protective member to an overshoe-like mounting member, it can be easily worn while wearing normal footwear such as shoes, rubber boots, and underground socks. Therefore, it is possible to protect the insteps of visitors and inspectors at the site where safety shoes are required, without having to change the shoes. Moreover, since the said protection member is hold | maintained in the position where the lower end edge of the leg part of a protection member is above a grounding surface by a holding means, a protection member does not interfere with walking. Furthermore, when the impact is received on the curved portion of the protective member, the leg portion of the protective member contacts the ground and prohibits the curved portion from moving in the direction of the instep, so that the impact is transmitted to the instep portion of the wearer's foot. I can stop. In addition, when the mounting member or the protection member is worn, only the worn member needs to be replaced, so that the cost can be reduced. Note that footwear is a concept that may include shoes, basement socks, sandals, sandals, clogs, and the like. In addition, the ground contact surface is a concept including all surfaces such as a ground surface, a pavement surface, a building floor surface, a staircase surface, and the like that come into contact with the bottom surface of such a shoe protector.

The thing which consists of a hole is mentioned.

  If the attachment member has an attachment bottom portion that supports the bottom portion of the footwear, and an attachment member body that is formed of an elastically deformable material and urges the footwear to be fixed to the attachment bottom portion, elastic deformation is possible. Since the mounting member body made of a simple material urges the footwear to be pressed down, the footwear can be effectively brought into close contact with the shoe protector, and the shoe protector can be securely attached. be able to.

  Further, if the protective member is formed in a symmetrical shape with the center in the width direction as the center, the protective member having the same shape is attached to the left foot side mounting member and the right foot side mounting member. This makes it possible to share parts, so that further cost reduction can be achieved.

  In addition, if the protective member is made of a synthetic resin, the weight can be reduced while maintaining the same rigidity as the aspect of attaching a core made of a conventional steel plate to a shoe. Thus, it is possible to reduce a sense of incongruity during walking, running, etc. in a state where such a protective equipment for shoes is worn.

  If the protective equipment for shoes according to the present invention is adopted, the protective member is attached to the overshoe-like attachment member, so that it is easy to wear footwear such as normal shoes, rubber boots, and underground socks. It can be worn, and it is possible to protect the backs of visitors and inspectors at the site where safety shoes are required, without having to change the shoes. Moreover, since the said protection member is hold | maintained in the position where the lower end edge of the leg part of a protection member is above a grounding surface by a holding means, a protection member does not interfere with walking. Furthermore, when the impact is received on the curved portion of the protective member, the leg portion of the protective member contacts the ground and prohibits the curved portion from moving in the direction of the instep, so that the impact is transmitted to the instep portion of the wearer's foot.
