Abstract
The invention pertains to a footwear stretcher apparatus comprising: two spacer blocs separated by a wedge-shaped gap and configured to be inserted inside walls of a footwear; an actuator; and a wedge, driven by the actuator, and configured to change a spacing of the wedge-shaped gap proportional to a stroke of the actuator, thus stretching the walls of the footwear.
Claims10
A footwear stretcher apparatus comprising a first stretching set comprising:
- two spacer blocs separated by a wedge-shaped gap and configured to be inserted inside walls of a footwear;
- a first power actuator;
- and
- a wedge, driven by the first power actuator, and configured to change a spacing of the wedge-shaped gap during a stroke of the first power actuator, thus stretching the walls of the footwear;
- wherein the two spacer blocs are two shaft spacer blocs configured to be inserted into a shaft of the footwear and comprising a conical shape of a semi-circular section and wherein the wedge is a circular puck, attached to an end of a rod of the first power actuator and configured to translate in the wedge-shaped gap between the two shaft spacer blocs;
- and, wherein the circular puck has a round outer flat edge which engages the two shaft space blocs
- wherein the two shaft spacer blocs are each connected to a frame at a proximal end by a connecting rod comprising a first pivotal link with the frame and a second pivotal link with the shaft spacer bloc.
