Abstract

A table positioner is disclosed for use with radiographic equipment to cause smooth translating and continuous angular movement of the table in reciprocal directions from a lengthwise horizontal position to lengthwise vertical positions. When in a lengthwise horizontal position, the positioner causes the top of the table to have a sufficiently low vertical height above floor level to enhance utilization of the radiographic equipment for imaging of a patient on the table, and yet still allows lengthwise angular movement of the table from this low horizontal positioning to full vertical positioning with the then lower end of the table being maintained in a position close to floor level but precluding floor contact during any portion of table movement. Lengthwise angular movement of the table is effected through use of a pair of gear racks mounted on a moveable frame with the gear racks being curved in opposite directions with respect to one another and engageable with drive gears one of which is mounted on a pivotable yoke mounted on the frame and operating in conjunction with the gear racks and drive gears to effect the smooth translating and continuous motion of the frame.
