Abstract:
An automated chest percussor apparatus comprising:a housing having ends and a bottom wall;a plurality of adjustable telescopic legs upon which said housing is securely mounted, said adjustable telescopic legs being securely attached to said ends of said housing, each of said adjustable telescopic legs including a base tubular member having an open end, and also including a housing support member which is securely attached to said housing and which is adjustably extendable through said open end of said base tubular member, and further including a height adjustment member being threaded through said base member and being engageable to said housing support member;a means for providing chest percussions, including a motor disposed inside said housing; a rotatable shaft connected to said motor; a first cam securely mounted about said shaft; and a second cam securely mounted about said shaft and being spaced from said first cam; and a means for providing chest percussions, said means for providing chest percussions comprising a first tubular member being in contactable relationship with said first cam and movably extending through said bottom wall of said housing; a second tubular member being in contactable relationship with said second cam and movably extending through said bottom wall of said housing; a first flange member being securely disposed about said first tubular member; a second flange member being securely disposed about said second tubular member; a first spring member being mounted about said first tubular member for urging said first tubular member upwardly through said bottom wall of said housing; a second spring member being mounted about said second tubular member for urging said second tubular member upwardly through said bottom wall of said housing; a first percussor member being adjustably threaded through a bottom end of said first tubular member; and a second percussor member being adjustably threaded through a bottom end of said second tubular member, said first tubular member having an upper end which is in contactable relationship with said first cam which is adapted to urge said first tubular member downwardly through said bottom wall of said housing; said second tubular member having an upper end which is in contactable relationship with said second cam which is adapted to urge said second tubular member downwardly through said bottom wall of said housing, said first flange member being securely disposed about said upper end of said first tubular member; said second flange member being securely disposed about said upper end of said second tubular member, said first spring member being disposed against said first flange member and said bottom wall of said housing; said second spring member being disposed against said second flange member and said bottom wall of said housing, said first percussor member including a first threaded shaft and a first padded member disposed about a bottom end of said first threaded shaft, said first threaded shaft being adjustably threaded with a first adjusting member through a bottom end of said first tubular member; said second percussor member including a second threaded shaft and a second padded member disposed about a bottom end of said second threaded shaft, said second threaded shaft being adjustably threaded with a second adjusting member through a bottom end of said second tubular member, said first and second padded members being in contactable relationship with a person's chest, wherein said first percussor member and said second percussor member being mounted on said housing in a manner permitting movement of said first and second percussor members such that said first and second percussor members are simultaneously moveable in opposite directions, said first cam being positioned on said shaft at a circumferential location opposite a circumferential location of said second cam on said shaft such that said first cam moves said first percussor member in a direction substantially opposite of a direction that said second cam moves said second percussor member;said motor being a variable speed motor, a means for providing chest percussions further including a support bracket securely disposed inside said housing, a first bushing securely mounted to said support bracket and supporting said rotatable shaft, a second bushing disposed inside said housing and supporting said first tubular member, and a third bushing also disposed inside said housing and supporting said second tubular member; anda power and control source for energizing said means for providing chest percussions, said power and control source including a box-like member, a battery disposed therein, an on/off switch for energizing said motor, a speed control member for controlling the speed of said motor, an adapter socket for recharging said battery, and a power socket to which a cable is inserted to energize said motor.
