Abstract
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.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
304 words
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.

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.
Claim 3
Dependent Claim
22 words
A tiltable table as stated in claim 1 including pads affixed to said tubular member, said foot rest and said head rest.
Claim 4
Dependent Claim
74 words
A tiltable table as stated in claim 1 including a first limit switch for automatically stopping said tubular member when it reaches said horizontal plane, a second limit switch for automatically stopping said tubular member when it reaches said near-vertical plane and a third limit switch for deenergizing said electric motor when said foot rest is swung to a depending position with respect to said tubular member when it is in its horizontal plane.
Claim 5
Dependent Claim
247 words
A tiltable table as stated in claim 1 including: a shaft rotatably mounted in said first end of said tubular member, said shaft being provided with a land located within said tubular member and having its ends extending to positions outside said tubular member; a latch plate slidably mounted in said first end of said tubular member, said latch plate having a first end adapted to be pulled under said land when said shaft is in a first rotated position to prevent rotation of said shaft and being adapted to stop against said shaft when said land is rotated away from said first position; a spring connected to said latch plate and to said tubular member for biasing said latch plate toward said shaft; a knob attached to said latch plate for pulling it away from said land; and a limit switch mounted in said tubular member adjacent the end of said latch plate which is remote from said shaft for engagement by said latch plate when it is slid out from under said land, whereby said motor is deenergized, said foot rest including a pair of arms each having an end affixed to one of the exposed ends of said shaft and a foot plate affixed to the upper surface of said arms, said foot rest being related to the rotated position of said shaft such that said latch plate will be drawn under said land only when said foot rest is in a patient-receiving position.
Claim 6
Dependent Claim
26 words
A tiltable table as stated in claim 1 including a hand grip assembly affixed to said second end of said tubular member beneath said head rest.
Claim 7
Dependent Claim
44 words
A tiltable table as stated in claim 1 wherein said head rest comprises: a pair of arms swingably connected to said second end of said tubular member; and a head piece slidably mounted on each arm for movement from abutting positions to separated positions.
