Abstract

"IMPROVEMENT ON ERGOMETRIC MAT". Of the type comprised of a metal frame or frame formed by a basic rectangular frame under which support feet and castors are defined, said frame formerly supporting a traction unit, a pair of substantially vertical arms, said handlebars, on which A control and monitoring panel of the equipment is mounted, and in the horizontal plane of the basic frame is provided a pair of rollers around which is mounted an endless blanket, said conveyor belt, where its upper and lower horizontal portions are interspersed by a rigid board of contour and shape compatible with that of the basic frame. Between the basic frame (1) and the rigid board (8) is provided the inclusion of an elastically deformable and adjustable pressure chamber (20) disposed under the user's support platform (7a, 8); wherein the pressure chamber (20) is held between the rectangular plate (8) and the metal frame (1) supporting and supporting the equipment (10) close to the ground; the pressure chamber (20) being selectively and automatically calibrated to provide the user support platform (7a, 8) with a degree of external impact cushioning and a degree of user supportability commensurate with its weight and to enable gradation pressure that determines levels of flexibility of the user support platform (7a, 8), from a softer condition (low pressure) to a harder condition (high pressure), with the chamber being manually pressurized by pumping means mechanical and / or electrical.
