Abstract
In an extensible shoe shaper, the toe and heel are connected by means of a kinematic hinge element, formed of a plastic material strip of varying thickness applied by pressure, the configuration of which can be varied--in order to vary the extension of the shaper--by means of a screw handwheel, slidably fixed to the toe and acting on said kinematic element.
Claims4
Extensible shoe shaper having a front toe part and a rear heel part, characterized in that, the connection between the front part and the rear part is obtained by means of a kinematic hinge element formed of a single strip of material of varying thickness, wherein the hinge function is performed by portions of reduced thickness of the strip of material, and the configuration of the hinge element can be varied by means of a screw handwheel which is slidably fixed along one of said parts and acting on said hinge element.
