March 23, 1954 J. N. GROSS 2,672,620 PATIENT HANDLING DEVICE FOR BATHTUBS Filed Feb. 11, 1952 7 7 an I l5f8 (I9 20 FIG. 2 f f 7 INVENTOR. JOHN M GROSS AGE/VT supports or reduced rods 9 and N are reciprocally slidably mounted. These tray extension supports 9 and 10 are retained in the hollow tubular members la and 6:1 by means of the retainers H and 12 which are pivoted spring clip members mounted on the arms 4 and 6 as shown best in Figs. 1 and 2 of the drawings. It will be here noted that the hollow tubular members 4a and 6a are fixed to the arms 3 and 5 providing unitary movement of the arms 3 and 5 with the arms 4 and 6. These members 4a and 6a provide a support for. the tray l3. This tray I3 is provided with notched bearing portions l3a and i312 which notched bearing portions engage the hollow tubular members 6a and 4d respectively. The shaft I8 is mounted in the casing 20 by means of the bearings Illa and fixed on this shaft l8 are the worm gears 16 and I1 meshing with the gears l4 and I5 respectively. The motor I9 is a reduction gear motor coupled with the shaft It for driving the same. The casing 20 encloses the driving mechanism for my patient handling device for bath tubs and the entire structure thereof, including the elevating means hereinbefore described, is connected to the frame 2 which is.

readily removably inserted in a conventional bath tub.

The operation of my patient handling device for bath tubs is substantially as follows:

When it is desired to lower a disabled patient into the bath tub I, the conventional portable cot, is rolled into position adjacent the bath tub i and the motor 19 is energized which rotates the shaft 18 turning the gears lb and il in mesh with the gears It and 65 respectively causing rotation of the shaft 2 and 8 which pivots the arms 4 and 6 and 3 and 5 respectively'elevating the tray on the hollow tubular members ist and to to a position substantially on a level with the upper surface of the portable cot on which the disabled patient is located, all as indicated by dash lines in Fig. 3 of the drawings. When the arms 3, 4, 5 and G are in such elevated position the tray extension supports 9 and it are released by pivoting the retainers H and 52 to the dash line positions as shown in Fig. 2 of the drawings permitting these extension supports to be axially slid outwardly of the tubular members do and 6a to the extended dash line position beyond the side of the bath tub whereupon the tray i3 is supported beyond the side of the bath tub in close proximity with the portable cot on which the disabled patient is located. The Patient, is rolled off the tray l3 which is then retracted to a position over the bath tub I by slidably retracting the tray extension supports 9 and I and latching them into position by means of the retainers H and I2. The motor 19 is then energized which causes reverse rotation of the shaft 18 together with the shaft 7 and 8 which gently lowers the tray 13 into the bottom of the bath tub i and immerses the disabled patient in the bath.

It will be here noted that a conventional electrical circuit and suitable limit switches-may be provided for the purpose of stopping the pivotal movement of the arms 3, 4, andi atthe 'de sired locations to correspond with certain requirements.

Though I have shown and described a particular construction, combination, and arrangement of parts and portions, I do. not wish to be, limited ,to' this particul r;-construction, combined-f tion and. arrangement but desire; to include in: thescope of my invention,- the construction, com.-

bination and arrangement substantially as set forth in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Pat 1. In a patient handling device for bath tubs, a frame adapted to be removably inserted in a bath tub, trunnions on said frame, a pairiof arms pivoted on said trunnions at each side of said frame, hollow tubular members interconnecting said arms, a tray positioned over said hollow tubuiar members, means for driving said arms for raising and lowering said tray, and means slidably mounted in said hollow tubular members being extendable laterally of said frame when said arms are elevated for supporting said tray beyond one side of said frame.

2. In a patient handling device for bath tubs, a frame adapted to be removably inserted in a bath tub, trunnions on said frame, a pair of arms pivoted on said trunnions at each side of said frame, hollow tubular members interconnecting said arms, a tray positioned over said hollow tubular members, means for driving said arms for raising and lowering said tray, means slidably mounted in said hollow tubular members being extendable laterally of said frame when said arms are elevated for supporting said tray beyond one side of said frame, said driving means comprising a shaft adjacent the side of and supported on'said frame and having gear means connected to said shaft for driving said arms, and a motor for operating said shaft.

3. In a patient handling device for bath tubs, a frame removably insertable into a bath tub, arms pivotally mounted in said frame, hollow tubular rods connected to and between said arms, reduced diameter rods slidably mounted within said hollow rods and releasable latches connected to certain of said arms and abutting said reduced rods, a tray mounted on said hollow rods and slidable relative thereto to provide for lateral extension of said tray and said reduced rods relative to said frame and said hollow rods when the arms are elevated to extend above the bath tub, and means for pivoting said arms for raising and lowering said tray.

4. In a patient handling device for bath tubs, a frame removably inserted in a bath tub, a shaft secured to one side of said frame, a motor operatively connected to said shaft, worm gears spaced apart on said shaft, pinion gears on said frame driven by said worm gears, arms pivotally secured to and actuated by said piniongears; a table pivotally secured to said arms whereby said table is raised and lowered relative to' said frame for placement and removal of said patient relative to a bath tub when said motor is energized.

5. In a patient handling device for bath tubs, a frame removably inserted in a bath tub; a shaft secured to one side of said frame, a motor operatively connected to said shaft, worm gears spaced apart longitudinally on said shaft, pinion gears pivoted on said frame and driven by said worm gears, a first pair of arms secured to and raised and lowered by said pinion gearst'a' second pair of arms'pivotally secured to said frame and being transversely opposite from said first pair of arms, hollow tubular rods transversely arranged relative to said frame and connecting said first and second pairs of arms, reduced diameter rods slidably mounted within said hollow tubular rods,

releasable-latches abutting said reduceddiameten rods andsecured to-said first pair of arms; a table "supported bylsaid hollow tubular rods, wherebyj said latches may be released and when said arms are elevated to extend above the bath tub said table may be moved transversely relative to said frame and supported on said reduced diameter rods extending laterally relative to said hollow tubular rods.

6. In a patient handling device for bath tubs, a frame removably insertable in a bath tub, pairs of arms pivotally secured in transversely opposing relation on the sides of said frame, horizontal 1 members rigidly secured to said arms and extending between the arms of each pair of arms, said members mounting supports longitudinally eX- tensible axially of said members when the arms are elevated above the level of the bath tub, a tray mounted on said horizontal members and slidable with and supported by said extensible supports for patient loading and unloading at the side of a bath tub wherein the device is mounted, and means for pivotally moving said arms for raising and lowering the tray relative to said frame.
