Abstract
A stabilizer device for connecting to the bottom support surface of a machine or article of equipment for supporting such equipment on a floor surface having a foot-actuated rotor for adjusting the length of the stabilizer shank and thereby stabilizing and balancing such equipment.
Claims14
A stabilizer device for attachment to the support structure of a machine or piece of equipment comprising:
- a) a threaded shank having a first end and a second end, the first end arranged to be rotatably adjustably connected to said support structure, and the second end including a head section adapted for engagement with a floor surface, and
- b) a foot-actuated rotor assembly rigidly connected to the shank near the head section of the shank, said rotor assembly including a hub section and a plurality of non-weight bearing blades each having top, bottom, side, and outer surfaces, said blades extending radially outwardly from the hub section of said rotor assembly at an acute angle with respect to the hub section and the first end of the shank of between about fifteen and thirty degrees, said bottom surfaces of said blades being wider than said top surfaces such that the side surfaces of each of said blades are outwardly angled from said top surface to said bottom surface, and the section of the side surfaces of said blades adjacent said outer surfaces is inwardly angled with respect to said outer surfaces, the side surfaces of said blades spaced apart to allow a portion of a user's foot or shoe to be engaged against a side surface of one of the blades to apply a manual turning force sufficient to rotate the shank with the head section in contact with the floor surface and the stabilizer bearing at least a portion of the weight of the machine or piece of equipment, to adjust the length of the shank extending from said support structure.
A machinery level stabilizing kit comprising:
- a) individual sections of at least one foot-actuated stabilizing device inclusive of;
- (1) a rotor having a central portion and a plurality of arms, each of the plurality of arms having a top surface and a bottom surface extending outwardly from said central portion,
- (2) a central threaded shank upon which the rotor is mounted, the shank having a floor engaging surface on one end, and
- (3) a threaded mounting for attachment to a leg of a machine mount,
- b) a containment means for temporary separation, display and storage of individualized portions of the at least one foot actuated stabilizing device,
- c) said individualized portions being ready for assembly into at least one foot actuated stabilizing device for mounting upon machinery supports for stabilizing heavy machinery;
- d) wherein the rotor of said at least one stabilizing device has its outwardly extending arms deviated to one side at an acute angle of from fifteen to thirty degrees with respect to the central portion of said rotor;
- and
- e) wherein the bottom surface of each of said plurality of arms is wider than the top surface to provide outwardly angled side walls extending between said top and bottom surfaces.

A foot-actuated rotor adapted to be rigidly connected to a rotatably adjustable machine stabilizer device, comprising:
- (a) a hub section;
- and
- (b) a plurality of non-weight bearing foot receiving blades extending outwardly from the hub section at an acute angle with respect to the hub section,
- (c) said blades having a midsection and an end section and top, bottom, side, and outer surfaces and being dimensioned to allow a portion of a user's foot or shoe to be repeatedly engaged against any of the side surfaces of the blades to apply a manual turning force sufficient to rotate and adjust the length of the stabilizer,
- (d) the blades having a gradually greater width from said midsection to said end section, forming an inward angle along said side surfaces with respect to the outer surfaces of the blades;
- (e) the bottom surfaces of said blades having a greater width than the top surfaces such that the side surfaces of each of the blades are outwardly angled from said top surface to said bottom surface.
