Lever particularly for sports shoes

A fastening lever assembly for sports shoes, comprising:

• a support rigidly couplable to a first flap of a shoe, said support including a plate rigidly couplable to said first flap of the shoe and further including two wings protruding laterally from said plate;
• a lever arm rotatably connected at a first end to said support, the first end of said lever arm being pivoted to said wings;
• an auxiliary lever for the user for temporarily increasing a working length or moment arm of said lever arm, said auxiliary lever being rotatably mounted to said lever arm at a pivot, said auxiliary lever being biased by a substantially U-shaped spring to rotate in one direction about said pivot, said spring having a base or middle portion in contact with a major lateral surface of said auxiliary lever, said spring having wings or end portions wound coaxially around said pivot, said spring having free ends in contact with a major lateral surface of said lever arm;
• a connecting member for connecting to an elongated member, said connecting member being rotatably linked to said lever arm at a point between said first end and said second end, said elongated member being provided with a tooth for forming a selective attachment to a rack securable to a second flap to be joined to the shoe, said auxiliary lever having a shape and said spring having a disposition so as to force said auxiliary lever to arrange itself adjacent to said lever arm with a free end of said auxiliary lever being directed toward said tooth.

A fastening lever assembly for sports shoes, comprising:

• a support rigidly fixable to a first flap of a shoe, said support including a plate which can be rigidly coupled to said first flap and from which two wings protrude laterally;
• a lever arm rotatably coupled, at a first end, to said wings of said support;
• an auxiliary lever pivotably secured to a second end of said lever arm for temporarily increasing a working length or moment arm of said lever arm, said auxiliary lever being rotatably mounted at one end to said lever arm at a pivot oriented at substantially right angles to said wings of said support;
• a connecting member for connecting to an elongated member, said connecting member being rotatably linked to said lever arm at a point between said first end and said second end, said elongated member being provided with a tooth for forming a selective attachment to a rack securable to a second flap to be joined to the shoe;
• and
• a flexible torsion spring coaxial with said pivot and locked at opposite ends to said lever arm and said auxiliary lever, said torsion spring exerting a restoring force to bias said auxiliary lever into an inactive position substantially parallel to said lever arm.
