Abstract:
An antislip device for footwear, comprising a holder used by being fixed to the bottom of footwear, and an antislip body to be held in said holder, said antislip body having an antislip portion that, when the antislip body is held in the holder fixed to the bottom of the footwear, contacts a surface to be trod by the bottom of the footwear so as to prevent the footwear from slipping relative to said surface,said holder and said antislip body have a holder-associated fitting portion and an antislip body-associated fitting portion, respectively, that fit together, said holder-associated fitting portion and said antislip body-associated fitting portion have a transverse support mechanism capable of preventing a relative movement between them in a direction orthogonal to the direction of fit when said antislip body-associated fitting portion fits in said holder-associated fitting portion, of such things as a slip-off preventive recess and a slip-off preventive projection capable of fitting in said slip-off preventive recess when the holder-associated fitting portion and the antislip body-associated fitting portion are fitted together, one is possessed by the holder and the other by the antislip body, either said holder or antislip body has a cantilever-like portion having elasticity, said cantilever-like portion has said slip-off preventive projection, either said slip-off preventive recess constituting portion or said slip-off preventive projection possessed by the cantilever-like portion is urged by the elasticity of the cantilever-like portion in a direction in which it can be fitted to the other, said slip-off preventive recess and said slip-off preventive projection being shaped such that when they are relatively moved in a direction in which they are fitted together, they can be fitted together and when they are relatively moved in the opposite direction, their fitting is not canceled, radially outside the slip-off preventive recess, one or more insert receiving portions being provided in which fit-canceling inserts can be inserted when the antislip body is in the state of being held in the holder fixed to the bottom of the footwear, said urged slip-off preventive recess constituting portion or slip-off preventive projection canceling the fit between the two by a canceling force opposite in direction to said urging force that the cantilever-like portion receives outside the slip-off preventive recess from the inserts directly when the fit-canceling inserts are sufficiently inserted in the insert receiving portions.
