  • the invention aims to provide a individual elevation device which allows both normal ground walking even in squatting position, instant elevation to desired height, stationary high, and being hands free to work at height and finally a rapid descent, this with a simple, light system, very compact and inexpensive due to the non need for an external energy source.
  • the invention relates to a device for equipping height-adjustable hands-free heightening such as stilts of the type consisting of tubes and / or mutually movable profiles, characterized in that it comprises on the one hand a fixed part B equipped with a locking member intended to be controlled at variable height between a high and low position and provided on the one hand with fixing means below the knee and foot of the user and on the other hand in the lower and lateral part of a rigid pad forming foot support extending forward to the foot portion of the user allowing the articulation of the end of said foot for walking in the low position almost normal and on the other hand a movable part A movable relative to the fixed part B under the action of a spring and comprising on the one hand complementary means blocking the fixed part B on the one hand and on the other hand a rigid non-slip pad positioned at its base intended to constitute a permanent support surface on the ground.
  • the tube of the mobile part is slidably mounted telescopically in the tube of the fixed part B and has a section such as square or rectangular so as to oppose a rotation between the two tubes and the means complementary blocking means are arranged at least at the ends, high and lower and intermediate of said tube and the spring is a compression spring arranged internally to the tubes and whose thrust is significantly less than the weight of the user allowing, on the one hand, the damping of the body weight during the reentry movement of the mobile part when locking downhill and secondly, the automatic extension of the tube for ascent when placing the leg in an oblique position.
  • the internal movable sliding part is extended by a fixed rectangular or oval shoe extending in the direction of travel and the pad on which the body rests has two edges: 1 edge in front of the heel and 1 behind the heel to avoid slipping of the foot and its length from the heel does not exceed 2/3 of the foot length to release the articulation of the tip of the foot for almost normal walking on the ground and to allow, in at the same time, in the extended position, the balance of the user's high immobile position, the shoe of the mobile part is an extension of the tube of the mobile part A, so that either position itself laterally on the shoe of the fixed part in the slightly retracted position raised, either to be arranged laterally to the tube of part A so as to come position under the pad of the fixed part B in the retracted position of the tube of part A.
