Electric assistive skiing device

The device according to claim 10, comprising a locking latch comprising:

• a lower plate having a first face with a third corrugated section which is coupled to the first corrugated section of the fixed plate and a second face opposite to the first face, where a first toothed section is arranged,
• an upper plate comprising a second toothed section which is coupled to the first toothed section of the lower plate, preventing the upper plate from sliding with respect to the lower plate, the upper plate being fixed in an integral manner to the mobile plate on an opposite face,
• a first hole arranged at one end of the upper plate,
• a second hole arranged at one end of the lower plate in correspondence with the first hole,
• a fastening element which is inserted into the holes coupling the upper plate from the lower plate, allowing the upper plate and the lower plate from moving together in an integral manner.

An electric assistive skiing device, intended to be coupled between skis and ski boots binding to reduce the effort required by a skier and to increase the speed of movement of the skis wherein the skis are fitted with an upper face and a lower face, the device comprising:

• two fixed plates each intended to be fastened to the upper face of each ski,
• two mobile plates provided with a front and rear ends, each mobile plate intended to be linked to each ski binding boot and each mobile plate being slidably associated with one of the fixed plates,
• traction cables provided with a first end and a second end, the first end of which is connected to one end of the mobile plates for pulling the mobile plates forward and moving them relative to the fixed plates,
• springs, which are fixed between the mobile plate and the fixed plate to move the mobile plate backward when the cable is not pulling the mobile plate,
• an electronic unit comprising:
• a motor module, connected to the second end of the traction cables,
• a battery that supplies power to the motor module,
• a sensor module linked to each of the mobile plates which detects a forward movement of the mobile plates,
• a controller connected to the sensor module and to the motor module, which is configured to activate the motor module which pulls the cable linked to one of the mobile plates once the sensor module detects a forward movement of said mobile plate.
