发明名称 Safety shoe with toe protecting cap
摘要 A safety shoe having a toe protecting cap which is shaped to conform substantially to the tip of the shoe and is provided at its portion facing the sole of the shoe with an inwardly directed flanged rim. This toe protecting cap flanged rim is inserted into a groove provided in the vertical end face of the one piece sole and is retained therein by attachment of the upper of the shoe, whereby the upper groove wall is set back with respect to the lower groove wall by at least the thickness of the toe protecting cap. The shoe upper is attached to the lower groove wall. The manufacture of the safety shoe is simplified and production cost savings are realized by providing a one piece sole having a groove therein, whereby at least one of the height and depth of the groove is slightly less than the corresponding thickness and length of the flanged rim of the toe protecting cap. The flanged rim of the toe protecting cap is tightly inserted into the groove in the one piece sole until it bears against the front face of the upper groove wall so that the toe protecting cap is retained immovably in the groove.
