Safety Overshoe

Abstract

An overshoe has a hollow front part open at the rear so that the shoe is engaged therein, and a band to be passed behind the heel of the shoe. The band is structurally separate from the front part and connected thereto.

What is claimed is: 
     
         1 . An overshoe comprising:
 a hollow front part having an opened rear, so that a shoe having a heel can be engaged in said hollow front part,   and a rear band adapted to pass behind said heel of the shoe, the rear band being structurally separate from the front part and connected to it by connection means, wherein:   the rear band is a single-piece moulding, and   the front part and the rear band are made of one of an elastomer and a thermoplastics material.   
     
     
         2 . The overshoe according to  claim 1 , wherein the connection means comprise movement means allowing movement between the front part and the rear band. 
     
     
         3 . The overshoe according to  claim 1 , wherein the hollow front part has a sole that becomes thinner at said opened rear. 
     
     
         4 . The overshoe according to  claim 1 , wherein the hollow front part has a sole which, at a lower surface, extends towards said opened rear at least substantially as far as in line with the top of an area of the front part that goes up over the instep. 
     
     
         5 . The overshoe according to  claim 1 , wherein the hollow front part has a sole which is serrated and provided with studs, staggered longitudinally. 
     
     
         6 . The overshoe according to  claim 2 , wherein said movement means comprise, on sides of the front hollow part, two structurally separate parts comprising a projecting cylindrical pin terminating in a broadened head and assembled with a tubular barrel having a broadened head, said assembly passing into orifices in the front part and in the rear band. 
     
     
         7 . The overshoe according to  claim 1 , wherein, at the rear, the rear band has a tongue projecting upwards. 
     
     
         8 . The overshoe according to  claim 1 , wherein the front part is made from plastic material reinforced at the front by a shell which is more rigid than said plastic material and embedded in the plastic material in which the front part is formed. 
     
     
         9 . The overshoe according to  claim 8 , wherein the shell is made from non-metallic, non-magnetic composite material. 
     
     
         10 . The overshoe according to  claim 1 , wherein the connection means provided partly on the front part and partly on the band are made from malleable plastic material and are interengaged. 
     
     
         11 . The overshoe according to  claim 1 , wherein the rear band has laterally, on each side, a slot elongated in the direction of elongation of the rear band. 
     
     
         12 . The overshoe according to  claim 1 , wherein the rear band, which is in a single piece, broadens from front to rear. 
     
     
         13 . The overshoe according to  claim 1 , wherein in front, on an instep, the front part has at least one protrusion elongated essentially horizontally and extending laterally. 
     
     
         14 . The overshoe according to  claim 1 , wherein the band has an elongation capacity greater than 1000%. 
     
     
         15 . An assembly of:
 a shoe having a heel, and,   an overshoe comprising:
 a hollow front part having an opened rear through which the shoe is engaged in said hollow front part, and, 
 a rear band passing behind said heel of the shoe, the rear band being structurally separate from the front part and connected to it by connection means, the rear band being a single-piece moulding, and 
 the front part and the rear band are made of one of an elastomer and a thermoplastics material. 
   
     
     
         16 . The assembly according to  claim 15 , wherein the connection means comprise movement means allowing movement between the front part and the rear band. 
     
     
         17 . The assembly according to  claim 15 , wherein the hollow front part has a sole that becomes thinner at said opened rear. 
     
     
         18 . The assembly according to  claim 15 , wherein the hollow front part has a sole which, at a lower surface, extends towards said opened rear at least substantially as far as in line with the top of an area of the front part that goes up over the instep. 
     
     
         19 . The assembly according to  claim 15 , wherein the hollow front part has a sole which is serrated and provided with studs, staggered longitudinally. 
     
     
         20 . The assembly according to  claim 16 , wherein said movement means comprise, on sides of the front hollow part, two structurally separate parts comprising a projecting cylindrical pin terminating in a broadened head and assembled with a tubular barrel having a broadened head, said assembly passing into orifices in the front part and in the rear band.
