Abstract
Table is moved from a near-vertical position to a horizontal position by a screw-type jack driven by an electric motor swingably mounted on a base member by a plate which also carries the jack assembly. The table includes an adjustable spreadable head rest and a foot rest. The foot rest supports the patient when the table is in its near-vertical position and may be swung to a depending position when the table is in its horizontal position. Interlock switches automatically stop the table in its near-vertical and horizontal positions. Another interlock switch takes the motor out of play when the foot rest is in its depending position with the table in its horizontal position so that the foot rest must be moved to a patient-supporting position before the table can be moved from its horizontal position to its near-vertical position.
Claims6
A tiltable table, comprising:
- a base member having first and second ends and an intermediate portion;
- a plate having an upper end and a lower end, said lower end of said plate being provided with a pair of wrist pins;
- a bearing block swingably connecting each of said wrist pins to said intermediate portion of said base member;
- an electric motor affixed to one side of said plate, said motor having an output shaft;
- a screw-jack assembly including a vertically-movable cylinder having an upper end and a lower end, a drive nut affixed to said lower end of said cylinder, a drive screw having one end threadedly engaging said drive nut to reciprocate said cylinder and another end drivingly connected to said motor output shaft and a screw bearing block rotatably receiving said another end of said drive screw;
- means affixing said screw bearing block to the other side of said plate;
- a table support including a pair of channel members each having an upper end and a lower end;
- means affixing the lower end of each channel member to said one end of said base member for maintaining said channel members in spaced-apart, near-vertical positions;
- a one-piece, elongated tubular member having first and second ends and an intermediate portion;
- a pivot pin swingably connecting the portion of said tubular member which lies between its first end and its intermediate portion to said table support between said upper ends of said channel members;
- means pivotably connecting said upper end of said cylinder to said tubular member between said pivot pin and said intermediate portion for swinging said tubular member from a horizontal plane to a near-vertical plane;
- a foot rest swingably connected to said first end of said tubular member;
- and
- a head rest swingably connected to said second end of said tubular member.
