  • a back rest comprising a flexible material 13 is suspended across the space between the tubular members 12c forming part of the seat supporting frame struc ture, sufliciently close to the seat support 14 to leave the major part of the space between said tubular members unobstructed so as to permit the seat supporting frame structure to be swung above the head of the user from the elevated position shown in Fig. 2 to the depending position of Fig. 4.
  • the swinging motion of the seat supporting frame structure may be facilitated by means of the arrangement illustrated in Fig. 5.
  • the armpit rests of the crutch elements are hollow and a tensioned helical spring 26 is mounted within the cavity of each armpit rest.
  • One end of this spring is attached to a pin 26a secured in the hollow casing forming the armpit rest 11, and the other end 25 of this spring is pivotally mounted on a pin 25:: carried by an arm 24 projecting from the free end of the rod 12b adjacent the turning axis 23 thereof.
  • Slits are provided in the hollow casing to permit movement of the end 25 of spring 26 and of the arm 24 relatively to the casing.
  • the arm 24 is in the position shown in full lines in the drawing.
  • the arm When the frame structure is swung to the elevated position through an angle of about 180 the arm will assume the position 24 shown in broken lines within the cavity of the crutch member 11. In both of these extreme positions the spring 26 is extended and will exert a torque on the frame structure through the arm 24 tending to assist the swinging motion of the frame about the axis 23.
  • Fig. 6 shows a modified construction of the seat supporting member.
  • the seat is mounted on the cross member of a U-shaped frame 44 suspended below the crutch members 11 by means of hook 41 engaging eyelets 42 pivotably mounted at 43 on the crutch members 11.
  • Fig. 7 illustrates the use of the supporting and transfer device for suspending an attachment comprising a cage-like frame structure adapted to grip a stretcher for carrying a person in horizontal position.
  • This cage structure comprising a pair of spaced apart frames 45 of substantially inverted V-shaped formation with intermediate bracing members 46, 47, 48 will clearly appear from the drawing and require no further explanation.
  • the extensions of the tubular arms 4 of the supporting frame comprise a pair of cantilever attachments 31 telescopically and adjustably mounted therein and provided with holes 32 for engagement with hook members 33 on supporting bars 34 for supporting a flexible seat 36 by means of straps 35.
  • a person seated in a chair as shown in Fig. 3 and preparing to rise to standing position first reaches over and places the crutch heads 11 in his armpits; then grips the handles 20 of the control lever 19 and operates this lever by small rapid reciprocating movements thereby operating the pump mechanism of the hydraulic hoist device 9a, 9b which tends to force the piston 91) downwardly. Since, however, this movement is arrested by the arm 10 rigidly secured to the base frame, the cylinder 9a will be forced upwardly and will raise the supporting frame to an angular position relatively to the base frame determined by the movement of the cylinder relatively to the piston 9b. During this movement, the person is gradually raised from the seated position to the standing position shown in Fig.
  • the hydraulic hoist device 9a, 9b is of the standard reversible jack type used for automobiles in which the relative movement of the cylinder and piston is automatically checked when the control lever is inoperative, it will be understood without further explanation that the device may be used for operation in the reverse direction, i. e. for lowering a person from standing to seated position by operating the normal release means used in such devices of well-known construction.
  • the device In Figs. 1 to 6 the device is illustrated in its function as a walker enabling persons who have been crippled or otherwise disabled to rise from a seat and to move about in perfect safety without requiring the help of attendants. However, when provided with the attachments shown in Figs. 7 to 9, it may further be used as a crane-like lifting and transfer device for safely transferring bed patients from place to place as from a bed to a bath tub or for lifting patients out of bed for placement of pans or change of linen. When used for such purposes, the device must be operated by an attendant, but it will be appreciated that such operation requires neither skill nor physical strength on the part of the attendant, and the device therefore presents considerable advantages as a labor saving auxiliary equipment for hospitals, invalid homes etc.
  • a device of the character described comprising a U-shaped base frame and a tubular U-shaped supporting frame hingedly connected therewith and including a pair of parallel rearwardly extending tubular arms, crutch attachments telescopically adjustable within said tubular arms, a seat supporting member pivotally connected with said crutch attachment and comprising a pair of substantially J-shaped supporting rods, the space between said supporting rods being left unobstructed to allow the supporting member to be swung about the crutch attachments above the head of a user positioned therebetween, a seat mounted at the end of said supporting member, a back rest mounted on said supporting member and extending between the supporting rods and operable means pivotally connected with said base frame and supporting frame to provide for swinging movement and angular adjustment of the position of the supporting frame relatively to the base frame.
  • crutch attachments comprise a pair of hollow arm rests each comprising a spring located within the cavity of the arm rest, pivots connecting the arm rests with the arcuate ends of the supporting rods, an arm extending from the end of each supporting rod and connected to one end of each spring within said arm rests.
  • a device as defined in claim 1 comprising a pair of downwardly projecting feet mounted on the web portion of the supporting frame to provide for blocking the base frame against its support when the supporting frame is swung downwardly towards the base frame.
