OHRBERG ATTORNEY United States Patent "ice 3,293,667 ADJUSTABLE, AMBULATlNG, TELTING AND RECLIINING BED John F. Ohrberg, 316 th Ave, Molina, Ill. 60610 Filed (Pct. 2t), 1965, Ser. No. 498,717 15 Claims. (Cl. 562) This invention relates to an adjustable, ambulating, tilting and reclining platform or bed provided for the comfort and relaxation of a person afflicted with cerebral palsy, muscular ailment, spastics, and for those in casts or braces than cannot be made comfortable in wheel chairs.
In many instances patients having ailments of the nature listed above are unable to sit or to sit for long lengths of time. Often their body parts will not support other body parts in a normal manner. Also, in many instances certain muscles and/ or nerves have weakened or deteriorated to an extent that they can no longer support or control portions of the body. Consequently it is desirable to provide a bed or platform that completely supports all the body parts so that the patient may be raised to and from a standing or vertical position and while in such a position be adequately protected and supported with a minimum amount of supervision.
With the above in mind, it is the primary object of the invention to provide a supporting structure for an invalid that provides adequate protection for a patient while he is reclined on a supporting platform that may be inclined to a substantial vertical position, and to further provide means on the platform that supports individual body parts on the platform.
Specifically it is an object of the invention to provide a cabinet supported on a mobile base and having an inclined front side and a horizontal top side, and a transverse hinge at the juncture of the two sides. A body supporting platform is supported on the hinge and may be swung thereon to various inclined positions as well as the horizontal position. Lock means is provided on the platform and cabinet to positively lock the platformin any selected position.
The platform is provided with a peripheral rod just outwardly of its edges and various and numerous body supporting and retaining members are carried on the rod. The members are adaptable for movement along the rod so that they may be adjusted to accommodate various parts of the body as well as various body sizes.
Other objects and advantages of the invention Will become apparent to those skilled in the art as the nature of the invention is better understood from the description and as shown in the accompanying drawings.

The patient supporting device includes a main support in the form of a cabinet 11 having a floor portion 11, left 3,293,667 Patented Dec. 27, 1966 and right hand upright sides 12, 13, and an inclined transverse front side 14 that interconnects the front edges of the sides 12, 13. An upper horizontal shelf or ledge 15 connects the upper edges of the sides 1214 and serves as a top of the cabinet. A mid-shelf 16 extends between and is connected to the sides 12-14 intermediate the floor 11 and top 15. The cabinet 10 is generally open at its rear for access thereto and is utilized for storing attachable parts.
The cabinet 10 receives mobility by front Wheels 17, 18 fixed to the cabinet at the front lower corners, and rear wheels 19, 20 fixed to the cabinet at the rear lower corners. A braking device is provided at the rear lower corners and includes a pair of upright rods 21 supported for vertical movement and connected at their lower ends to vertical shafts 22 supported for vertical movement in vertical guides 23 that are fixed to the respective side walls 12, 13 at their lower rear corners. The lower ends of the shafts 22 have rubber tips 24 that frictionally engage the floor. A pair of levers 25 is supported on transverse horizontal pivots 26 and have a crossbar interjoining their rear ends so that both the levers and tips 24 are raised in unison. The levers are on the side walls 12, 13 for vertical movement at the top and rear of the cabinet 10, the levers being provided for gripping and pushing by a nurse or other person caring for a patient. The upper ends of the rods 21 connect to the levers 25 so that upon raising the levers the tips 24 are raised from the floor. The weight of the levers 25, when released, in conjunction with the weights of the rods 21 and shafts 22 creates sufiicient downward load to maintain astrong frictional resistance to movement between the tips 24 and the floor.
A pair of transversely aligned hinge brackets 30, 31 is fixed to and projects upwardly from the cabinet 10 at the front uppen corner thereof or at the juncture between the inclined side 14 and tip 15. The brackets carry a transverse horizontal hinge rod 32 on which is carried a pair of hinge plates 33, 34 that is bolted or fixed to the underside of a body supporting platform 35 the midportion thereof. The platform 35 is therefore permitted vertical movement between a vertical position, although slightly inclined, as shown in FIGS. 2 and 3, and a horizontal position as shown in FIG. 1. A pair of abutment rods 36 depend from the underside of the platform so as to engage the top 15 adjacent its rear transverse edge and when in engagement therewith supports the platform in a substantially horizontal position.
Locking means are provided between the platform 35 A latching device is further provided to lock or latchthe platform in its horizontal position and includes a latch element 50 pivoted on the pin 40 to the underside of the platform. Connected to the latch element 50 is a control rod 52 that is guided for lengthwise movement on the underside of the platform 35 and terminates adjacent the upper or head end of the platform. The rod has a finger grip 53 at its end for convenience of an operator. A spring 54- extends between the element 51] and platform 35 for biasing it toward the lower end of the platform. Providedon the bracket 43 is a latch catch or abutment 55 that is complementary to the latch element 50 and engages it as the platform approaches the horizontal. operation, therefore, the spring 54 Will cause the latch element 50 to seat beneath the latch catch 55 when the platform is in the horizontal position. The rod 52 may be pulled for purposes of releasing the latch.
Provided on the cabinet sides 12, 13 are vertical guides 60 that receive the vertical legs of a pair of L-shaped rods 61, 62. The horizontal legs are adapted to extend above and forwardly of the platform when the latter is in either its respective horizontal and vertical positions. Identical marking indicia 63 is alongside the vertical legs so that the horizontal leg portions may be adjusted to identical heights. The horizontal portions serve as basic supports for such items as a table 64 (FIG. 2) that require a substantial horizontal disposition. The rods 61, 62 are clamped against movement in the guides 60.
The platform 35 is of rectangular shape and is bordered by a continuous pipe or rod 65 means spacedly outwardly of and adjacent the edges of the platform. The pipe 65 is supported on the platform by spaced apart brackets 66 that are screwed at 67 to the underside of the platform adjacent the edges and extend outwardly thereon and rigidly mount the pipe 65 on the platform 35.
Carried on the pipe 65 is a series of body supporting parts that project from the pipe over the upper surface of the platform. One of the body supporting parts is a footrest that includes a rigid plate 70 projecting perpendicularly from the upper surface of the platform 35 and across the platform. The plate is supported on side rods 71, 72, which are longitudinal sections of the pipe 65, by a pair of end brackets-73, 74 having lower tubular portions 75, 76 riding on the pipe or rod sections 71, 72 and upper clamps 77, 78 on the rods 71, 72 that may lock the foot support at the desired position on the platform 35. Thumb nuts 79 are used to tighten the clamps 77, 78 on the rods 71, 72. Small slots are provided in the end plates or brackets 73, 74 to receive ends of a fabric Wrap that may be passed over the ankles of a patient. As is clearly obvious, the foot support may be adjusted along the rods 71, 72 to the desired position in accordance with the height of the patient.
A second body supporting part is a plate device 80 composed in part of a small plate, in a preferred form of a short wooden block 81, that lies in a normal relation to the platform surface and is carried on a two-piece clamp 82 that is adjustable along the rod section. An adjustable two-piece bracket 83 connects the clamp 82 to the block 81 and the bracket 83 is adapted for articulation so that the two pieces may be adjusted both lengthwise and angularly relative to one another. A clamping bolt 84 is provided to lock the bracket 83 against articulation. The plate devices 80 normally operate in pairs with their b ing disposed on opposite sides of the body. In the positions as shown in FIGS. 3 and 4, they will engage and support the sides of the head. In a lower position along the rods 71, 72 the plate devices 80 may be turned on the brackets 83 so that the long dimension of the plates 81 extend from the face of the platform and consequently serves as arm rests for a patient.
A further body supporting means is in the form of a flexible fabric or tape 85 that is adapted to extend over the body. One end of the tape 85 is connected to a hook device 88 that is adapted to sit behind one of the rods 71. A bite is provided in the fabric 85 and a pin 89 inserted to comfortably engage a body part. Also, as tension is aptends through a buckle 87 which in turn is fixed to a second hook 86. The latter is adapted to hook or sit behind the other track 72. Takeup of the tape may be made through the buckle 87 until the tape is sufficiently tight to comfortably engage a body part. Also, as tension is applied to the tape, the hooks 86, 88 are locked behind the rods 71, 72 so that they will not accidentally disengage the rods.
A further form of body supporting means includes a pair of rods 90 that project forwardly from opposite edges of the platform 35 and are supported in cantelever fashion from bifurcated arcuate lugs 92, 93 that hook behind the rods 71, 72 and an inwardly extending flat surfaced lug 94 that bears against the edge and top surface of the plate or platform 35. A roll of fabric 95 extends between the rods and is disposed substantially perpendicular to the platform 35 and may be utilized as a soft undersupport of a patients feet or may be utilized for sitting purposes by a patient. As weight is applied to the fabric the lugs 92-94 bite into the rods 71, 72 and the platform 35 and frictionally holds the rods 90 against movement. The bifurcated lugs 92, 93 may also be placed on opposite sides of the connecting brackets 66 between the platform 35 and pipe 65 so as to lock it against any movement.
A further form of body supporting means is a relatively wide fabric binder 99 that extend across a patients body and is connected to the rods 70, 71 in a manner best shown in FIG. 6. The fabric has a sewn loop 100 in one end thereof that extends in the spacing between the rod 71 and edge of the platform 35. A pin 101 extends through the loop 100 above the rod and platform so as to lock the loop end of the fabric 99 on the rod. The fabric binder 99 extends outwardly of an around the rod 71 and then upwardly and over the patient to the opposite rod 72. The opposite end of the binder is looped around rod 72 and connected to itself by a conventional type fabric connector 102.
It should be recognized that all of the body supporting parts have the adaptability of adjustment along the rods 71, 72. Also, while not shown, the body supporting parts may be supported on the transverse portion of the pipe 65 that extends across the 'head end of the platform 35. Further, the pipe 65, both at the top and along the sides operates as a hand gripper to aid in raising and lowering the platform.
Referring now to FIGS. 11 and 12, the table 64 is formed of a rectangular shaped top piece 105, preferably of wood, with a wooden depending border board 106. The piece 105 has an arcuate recess 107 conforming to the shape of a body so that it may fit around and relatively close to the body. The horizontal legs of the L-shaped rods 61 fit respectively between a downwardly opening notch formed on one side by the depending border 106 and on the other side by an end of transverse wooden bar 108 on the underside of the top piece 105. Opposite ends of the bar 108 are reduced at 109. A latching bar 110 is pivoted at 111 on the reduced end 109 of the bar 108 to swing under the rod 61 and lock the rod in the aforesaid notch and prevent accidental tipping or lifting of the table 64.
The table 64 may be utilized as a table for reading, or arm rest, or as a tray for supporting food. Since it is supported on the cabinet 10 it will always be in a horizontal position regardless of the inclination of the platform 35.
