Claim:
An elevator for raising and lowering a hot plate or grate located in a barbeque grill comprising: a first ensemble comprised of a first gutter, a second gutter and a third gutter assembled in the form of an upright “U”, the first gutter and the third gutter, being upright and each having inner grooves which face each other; a second ensemble comprised of a fourth gutter ( 5 ) which is horizontal and which has a pair of plates located on opposite ends thereof, each plate having a pair of rollers ( 8 ), the plates and rollers received within the facing inner grooves of the first ensemble; a third ensemble composed of fifth, sixth and seventh gutters assembled in the form of a horizontal “U”, the third ensemble supporting the hot plate or grate and having mortised ends which engage the fourth gutter ( 5 ), fixing the third ensemble thereto, the third ensemble being slidable upwardly and downwardly, guided by the plates located within the inner grooves of the first ensemble, enabling the hot plate or grate supported thereon to be moved closer to or more distant from a source of heat for the barbeque grill, one plate of the fourth gutter having a pivot with a groove which engages a cable which forms a closed loop between a first pulley and a second pulley, the cable being fixed to the pivot by a fixer, such that moving the cable moves the fourth gutter ( 5 ) upwardly and downwardly, as the rollers ( 8 ) slide along inner walls of the inner grooves, the first pulley being rotatable on an axle which is connected to a crank through a locking part and a crank pivot, being biased into engagement with each other by a spring, such that a user must push forward to free the crank pivot from the locking part to permit rotation thereof along with the first pulley, and, once the hot plate or grate is in a desired position, the first pulley is locked in place by the spring ( 22 ) which forces the crank pivot ( 20 ) back to a locking position engaged to the locking part ( 21 ) and, a leveling device for moving the third ensemble in a stabilized horizontal position comprised of a pair of flexible cables, a first cable having an end fixed to a top of the first gutter, and a second cable having an end fixed to a top of the third gutter, the fourth gutter having a first set of double pulleys mounted adjacent the first gutter and a second set of double pulleys mounted adjacent the third gutter, the first cable and the second cable passing down from the top and around the first and second sets of double pulleys, each cable crossing over to the opposed respective gutter, such that the first cable enters the inner groove of the third gutter and the second cable enters the inner groove of the first gutter, the first cable passing down the interior of the third gutter and having an end thereof fixed to a first tensioner ( 27 ) situated within the second gutter ( 2 ), and the second cable passing down the interior of the first gutter and having an end thereof fixed to a second tensioner situated within the second gutter.
