- Frank Spar-hawk, Akron, Ohio Application Aiiu 1a, Int Serial No. more 3 Claims.

1 This invention relates to bed construction, and more particularly to beds designed for use in hospitals, the primary object of the invention,

being to provide a mattress or mattress support embodying a plurality of movable sections so constructed and arranged, that certain sections may be elevated while certain other sections are lowered, thereby changing the locations of the portions of the mattress contacting the patient, for the comfort of the patient.

Another object of the invention is to provide a vertically adjustable frame supported within the bed, and so constructed that the frame may be elevated to lift the patient above the bed or mattress, the patient assuming an inclined posisition if desired.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts, hereinafter morei f filly described and pointed out in the claimsf it being understood that changes may be made in the construction and arrangement of parts without departing fiom the spirit of the invention as claimed.

Referring to the drawings Figure 1 is a longitudinal sectional view through a bed constructed in accordance with the invention, the plane of section indicated by line II,Fig. 2.

Figure 2 is a sectional view taken on line 2-2 of Figure 1.

Figure 3 is an end elevational view of the bed, portions of the foot posts being broken away to illustrate the supporting screws of the vertically adjustable frame.

Figure 4 is a perspective view of the frame, the adjustable back and leg rests thereof being shown in their raised positions.

Figure 5 is an enlarged fragmental elevation view illustrating the leg rest securing means.

Figure 6 is a sectional view taken on line 8-8 of Figure 2.

Referring to the drawings in detail, the bed comprises the usual side rails l which connect the head piece 6 and foot piece I of the bed, in the usual and well known manner.

The posts of the bed indicated at 8, are hollow and are formed with bearings 9 arranged therein, which bearings accommodate the vertical threaded shafts ll.

At the lower ends of the shafts II are secured pinions Ii that mesh with the pinions II that are secured at the ends of the horizontal shafts It the pinions II also meshing with the pinions 2 l4 secured to the ends of the horizontal shaft II that is mounted within one of the hollow side rails I.

A crank shaft l8 to which the crank I I is connected, extends into the post 8, at one corner of the bed, the shaft being provided with the beveled pinion I8 that meshes with one of the pinions H. Thus it will be seen that due to this construction, by operating the crank H, the vertical threaded shafts ill will be rotated simultaneously. Supported by the vertical threaded shafts I0, is a vertically adjustable frame embodying end bars I9 which are connected by means of the spaced parallel main bars 2!), the frame being of a size to fit over the upper portion of the bed. This frame is formed with an opening 4! disposed centrally thereof to permit the convenient use of a bed pan by the patient.

The bars 20 are formed with elongated openings 2| in which the pins 22 operate, the pins 22 extending laterally from the lower ends of the brace rods 23 that connect with the pivoted frame 24. The pins 22 of the brace rods 23 at the ends of the pivoted frame 24, are threaded to receive the wing nuts 25, whereby the frame 24 may be held in various inclined positions, for the comfort of the patient.

The pivoted frame at the foot of the bed comprises a plurality of pivoted bars 2i which are connected with the main bars 20, the outer or free ends of the bars 26 being connected by means of the rod 21. Supporting rods 28 have pivotal connection with the end bars 28 and extend downwardly through the pivoted keepers ll mounted within thebrackets 30, there being provided securing bolts 3| for securing the rods 2| in their positions of vertical adjustment.

Thus it will be seen that due to this construction, the pivoted frames or supports of the main frame It, may be adjusted vertically so that the patient may rest in a comfortable position.

The reference character 32 indicates bearings that are secured to the end bars I! of the main frame, the bearings being formed with internal threads to accommodate the shafts II to the end that when the shafts III are rotated, the main frame will be moved longitudinally thereof, so that the main frame may be adjusted to various heights.

In addition to the vertically adjustable frame, the bed comprises a plurality of spaced longitudinal bars 23 which have their ends secured to the head bars 32' and bars 34' of the foot piece I of the bed. These bars 32 are formed with openings arranged in spaced relation with re- 3 spect to each other. whichopenings accommodate the rods 34 of the heads 35. the lower ends of the rods being supplied with rollers 30.

Directly under the bars 33 are horizontal shafts 31 which have their ends mounted in bearings ll secured to the cross bars of the head and foot pieces of the bed. Cams 3! are secured to these shafts, and are designed to engage the rollers 36, so that as the cams rotate with the shafts 31, the rods 34 and heads 3! will be moved vertically.

The movement of the shafts 31 is accomplished by the operating rod 40 which has connection with the cranks 4| that are secured to the ends of the shafts 31, the operating rod I being connected with the crank handle 42, so that the shafts 31 will be moved simultaneously. The crank handle 42 is held in its positions of adjustment by means of a pin which extends therefrom, the pin being designed to be positioned in one of the openings 43 of the arcuate shaped keeper 44.

It might be further stated that alternate earns 39 of the shafts 31, are offset, so that when the shafts 3'! are operated, certain of the rods 34 and heads 35 will be elevated, while certain other rods 34 and heads 35 will be lowered, as clearly shown by Figure 1 of the drawings. In this way it will be noted that the supporting surface for the mattress or patient, may be varied changing the point of contact between the bed and patient, for the comfort of the patient.

What is claimed is:

1. A hospital bed comprising a supporting surface embodying a plurality of independent supporting members, a plurality of spaced longitudinal bars having openings, rods secured to the supporting members and being extended through the openings of the bars, rollers mounted on the lower ends of the rods, shafts disposed under the longitudinal bars, cams secured to the shafts directly under said rollers, a crank for operating the shafts, whereby the rods and supporting members are moved vertically.

2. A hospital bed comprising a supporting surface embodying a plurality of independent supporting members, a plurality of spaced longitudinal bars having openings, rods secured to the supporting members and being extended through the openings, parallel horizontal shafts mounted under the bars, rollers on the gods, cams on the shafts engaging the rollers, whereby rotary movement of the cams moves the supporting members vertically, said cams being offset with respect to each other whereby alternate supporting members are elevated above the adjacent supporting members.

3. A hospital bed comprising a frame, a plurality of transversely spaced parallel bars having openings formed therein, a supporting surface arranged that alternate supporting members are.

elevated, while certain other supporting members are lowered.
