ROMAN ZATIRALNY PRESS MACHINE Russian patent published in 2016 - IPC A63B21/00 

FIELD: sport.

SUBSTANCE: invention relates to physical culture and sports, in particular to sports and recreation equipment, and sports equipment. Substance of invention consists in that in a power simulator, a frame, on which a convergent, reversing working levers consists of left and right parts interconnected by beams, wherein upper beam is connected with frame additional links rigidity, and working levers are folded structure, front and rear parts with hangers for set of burdened and working handle, besides, in front part of working levers are located working natural handle grip changing in hammer, and isolating handle grip, and in rear part of working levers working handle natural grip, design of working lever is bent at an angle from 20 to 35 degrees to obtain required linear deviation rear working handles relative to front, design of working levers are rigidly installed in mounting seat arranged on frame at an angle from 15 to 30 degrees relative to horizontal line, with help of rigid joints of axial rotation, which consist of shafts of design of working lever at edges of shafts bearings are fitted in shells, in centre of cartridge are threaded holes for attachment of levers to carcass and bearing platform consists of base platform, linear displacement of slide bearing support and mounting seat, support is installed on slides of linear movement through joint of rigid axial rotation, and on platform base, by means of hinge rigid axial rotation of rear part of rail is arranged for linear displacement of tool, wherein slides are installed with possibility of movement along rail by means of auxiliary system, which is a linear electric drive, and on front part of rails installed three-joint assembly of rigid axial rotation, which is a central sleeve with bearings and pass through axis at edges of two lateral sleeves, lateral sleeves are rigidly connected to stop for legs, sleeve can be rotated to change angle stop for feet and fixation angle lock pin with lever-drive mechanism at axis, at outputs of central cartridge are lever thrust to lift rails, which second end articulated with auxiliary mechanism of linear electric drive and support mounting seat installed lower part to sled linear displacement, has holes for fixation and serves as rail sled for height adjustment, which are fixed on required height locking pin with lever-drive gear on slides to adjust height of platform is pivotally mounted ventilated seat mount seat to be locked at an angle of landing locking pin at platform bottom seat is arranged at center of seat thrust roller, a mounting seat consists of organic and ventilated seat, mounting seat is designed with possibility of its inclination angle adjustment due to linear pneumatic-movement mechanical unit, length of which is fixed by lock pin with lever-drive mechanism, linear pneumatic-movement mechanical unit via joint rigid axial rotation is installed on base carrying platform while upper end through joint of rigid axial rotation is installed to bearing support of mounting seat.

EFFECT: proposed power simulator is expansion of complex of exercises, higher safety and prevention of injury, during use, due to exclusion of load on spinal column when performing traction exercises on muscle of back, as well as wider range of users.
