Abstract: A molded wheel and bearing assembly includes two bearings in a molded housing forming a bearing assembly. The bearing assembly is molded into the hub of a caster wheel. The caster wheel is made by molding a hub around the bearing assembly, then molding a tread around the hub. No assembly of individual elements into the wheel is necessary.

Abstract: Treatment apparatus supporting a patient lying in a generally prone or supine position for manipulation includes a base and a table supported thereabove for movement between selected different horizontal positions or working levels for treatment of the patient. The table is tiltable toward and away from an upright position for facilitating the patient in mounting and dismounting before and after treatment and includes a foot piece adjacent an end of the table for supporting the patient when mounting and dismounting. A plurality of cushions are mounted for movement along the table to selectably adjustable positions for accommodating patients of different size and shape.

Abstract: A new and improved treatment table for supporting a patient in a face down prone position for chiropractic manipulation of the cervical vertebrae patient's spine includes a base extending upwardly of the floor to a convenient working level and a thoracic cushion for supporting a patient's body below the neck in the prone position at the work level. A headpiece is pivotally interconnected relative to the thoracic cushion for supporting the patient's head during manipulation treatment. The headpiece is pivotal about a laterally extending horizontal axis spaced at a level above the thoracic cushion and just below or at a level coincident with the patient's spine. The headpiece is also movable in lateral flexion about an upwardly extending axis and is rotatable about a roll axis generally coincident with the patient's spinal axis.

Abstract: An assist bar is provided for facilitating a standing chiropractor in the manipulative treatment of a prone patient's spine while the patient is supported on a leg support section of a chiropractic table of the type having a body support section for the patient's body pivotally interconnected with the leg support section. The assist bar includes a connector at one end for securing the bar to the leg support section remote from the pivotal interconnection of the section with the main body support section. The assist bar extends outwardly of the leg support section and a handle is provided adjacent an outer end portion for facilitating a chiropractor in manipulating the patient's lower body up and down or side to side while making adjustments in the patient's spine with the other hand on the patient's body on the body support section.

Abstract: A patient treatment table for supporting a patient laying in a generally horizontal position for treatment at an elevated level above the floor surface includes a base adapted to rest on the floor surface for supporting the table for movement between a first position for patient treatment and a second position for mounting and dismounting. The table includes a control system for moving the table between said positions having an electric motor and/or electrically activated hydraulic control valves and a safety system for deenergizing the electric motor and/or deactivating the control valves in response to a hazardous condition. The system includes a switch mat positioned on the floor surface adjacent the base which is operative to deenergize the electric motor and/or deactivate the control valves in response to pressure applied to the switch mat.

Abstract: A table for supporting a patient lying in a generally horizontal position for chiropractic manipulation includes a base projecting upwardly from the floor to a convenient working level and a pivotally mounted thoracic support section for supporting the thorax of the patient which is adjustable about an axis generally corresponding to the patient's spinal axis. The table includes a caudal section supportively connected to the base with ball joints permitting movement of the patient's legs in lateral caudal flexion from side to side about a generally vertical yaw axis and flexion movement about a laterally extending horizontal pitch axis in a vertical direction between upwardly sloping and downwardly sloping positions. A support cushion is mounted for rotation on the caudal section between a range of selected rotational positions about a longitudinal roll axis to accomplish caudal rotation of the patient. A leaf spring and adjustment assembly compensate for a patient's weight.

Abstract: An adjustable head support for a chiropractic table includes a base with a platen spaced above the base and interconnected for angular displacement relative to the base about an axis longitudinally thereof. An adjustable control system is provided for selectively controlling the amount of angular displacement between the base and the platen. The axis of rotational displacement of the platen is spaced above a head cushion supported above the platen and the axis generally coincides with the spinal column or vertabrae of a patient resting on the chiropractic table.

Abstract: A multi-step control apparatus is provided for raising and lowering a patient treatment table in response to predetermined successive motions of the foot of an operator. An operating rod mounted transversely of the table has a foot pedal on each end thereof and is biased to a mid position both longitudinally and rotationally. In response to inward pressure on either foot pedal a timing cycle is initiated during which the doctor may then initiate a raising or lowering cycle for the table by stepping on one side or the other of the foot pedal and rotating the operating rod out of a neutral rotational position. However, a raising or lowering cycle cannot be initiated without first moving the operating rod inwardly to initiate the timing cycle so that accidental or inadvertent raising or lowering of the table by simply rotating the foot pedal is prevented.
