Chiropractic adjustor apparatus having housing configured for enhanced heat dissipation and symmetrical force-transmitting shaft support
First Claim
1. A chiropractic adjustor apparatus, comprising:
- (a) a housing having a longitudinal axis, a central interior cavity extending about said longitudinal axis and a pair of opposite end portions oriented substantially the reverse of one another and extending in opposite directions from said central interior cavity along and about said longitudinal axis, said opposite end portions having respective inner surfaces spaced apart from one another by said central interior cavity and extending generally parallel to one another and extending about and perpendicular to said longitudinal axis of said housing, said opposite end portions further having respective outer surfaces of conical shapes spaced in opposite directions from central interior cavity and reversely oriented with respect to one another and extending about and along said longitudinal axis of said housing such that said opposite end portions are substantially mirror images of one another, said opposite end portions further having respective central openings therethrough extending in opposite directions from said central interior cavity and the housing further having passages adapted to enhance heat dissipation from said housing, said passages extending between and open at said respective outer surfaces of said opposite end portions and said central interior cavity and extending substantially parallel with said longitudinal axis of said housing and circumferentially spaced apart from one another about and displaced radially outwardly from said longitudinal axis of said housing and said openings through said opposite end portions of said housing;
(b) an electromagnetic drive mechanism mounted in said central interior cavity of said housing;
(c) an elongated force-transmitting shaft extending through said electromagnetic drive mechanism and through said openings in said opposite end portions of said housing and having opposite ends extending beyond said opposite end portions of said housing exteriorly of said housing, said shaft reciprocally supported by said opposite end portions of said housing in a substantially symmetrical relationship to said electromagnetic drive mechanism and, extending coaxially with said longitudinal axis of said housing;
(d) means for actuating said electromagnetic drive mechanism to cause repetitive reciprocal vibratory-type of movement of said shaft along a longitudinal axis of said shaft and relative to and along said longitudinal axis of said housing; and
(e) means attached to said housing for gripping to hold said apparatus.

Abstract
A chiropractic adjustor apparatus includes a housing having a central interior cavity and a pair of opposite end portions oriented substantially the reverse of one another and extending in opposite directions from the interior cavity and having passages adapted to enhance heat dissipation from the housing, an electromagnetic drive mechanism mounted in the interior cavity of the housing, a force-transmitting shaft extending through the drive mechanism and opposite end portions of the housing and reciprocally supported by the opposite end portions of the housing in a substantially symmetrical relationship to the drive mechanism, an arrangement for actuating the drive mechanism to cause repetitive reciprocal vibratory movement of the shaft along a longitudinal axis thereof and relative to the housing, and a handle attached to the housing for gripping the apparatus.

(b) an electromagnetic drive mechanism mounted in said central interior cavity of said housing;
(c) an elongated force-transmitting shaft extending through said electromagnetic drive mechanism and through said openings in said opposite end portions of said housing and having opposite ends extending beyond said opposite end portions of said housing exteriorly of said housing, said shaft reciprocally supported by said opposite end portions of said housing in a substantially symmetrical relationship to said electromagnetic drive mechanism and, extending coaxially with said longitudinal axis of said housing;
(d) means for actuating said electromagnetic drive mechanism to cause repetitive reciprocal vibratory-type of movement of said shaft along a longitudinal axis of said shaft and relative to and along said longitudinal axis of said housing; and
(e) means attached to said housing for gripping to hold said apparatus. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12)
an arrangement in the form of a knob on a rear end of said shaft and first and second springs disposed about said rear end of said shaft respectively interiorly between said stator and a rear end of said housing and exteriorly between said knob and said rear end of said housing, said knob being threadable into said rear end of said housing such that by turning said knob a return force imposed by said springs on said stator and shaft can be increased or decreased to thereby adjust the amount of vibratory movement applied to a surface at a front end of said shaft.

12. The apparatus of claim 1 further comprising:
a plurality of force transmitting elements of different configurations each adapted to be fitted to a front end of said shaft and adapted to be placed against a part of the human body to be treated such that vibratory impacts are transmitted at said front end of said shaft by a selected one of said force transmitting elements when placed against the part of the human body.

13. A chiropractic adjustor apparatus, comprising:
-
(a) a housing having a central interior cavity and a pair of opposite end portions oriented substantially the reverse of one another and extending in opposite directions from said central interior cavity, each of said opposite end portions of said housing having passages adapted to enhance heat dissipation from said housing, said housing being formed by a pair of separate housing parts arranged back-to-back in a reverse orientation with one another so as to define separately said opposite end portions of the housing and together said central interior cavity between said opposite end portions;
(b) an electromagnetic drive mechanism mounted in said central interior cavity of said housing;
(c) a force-transmitting shaft extending through said electromagnetic drive mechanism and through openings in said opposite end portions of said housing and reciprocally supported by said opposite end portions of said housing in a substantially symmetrical relationship to said electromagnetic drive mechanism;
(d) means for actuating said electromagnetic drive mechanism to cause repetitive reciprocal movement of said shaft along a longitudinal axis of said shaft and relative to said housing; and
(e) a handle attached to said housing for gripping to hold said apparatus, said housing parts assembled together by said handle fixedly attached on lower sides of said opposite end portions of the housing such that said handle underlies and bridges said housing parts in assembling said housing parts together and by an attachment member fixedly attached on upper sides of said opposite end portions of said housing such that said attachment member overlies and bridges said housing parts in assembling said housing parts together. - View Dependent Claims (14)
