9 Claims. (Cl. 62)
This invention relates to an improvement in hospital beds and one of its objects is to provide a hospital bed that not only may be adjusted to place a patient in various reclined positions, but also in a substantially vertical position.
Another object of this invention is to permit a patient to make his own adjustment of the bed.
Still another object is to provide a safe, rugged and adaptable structure that may be readily placed in its desired position.
At present, hospital beds are available which may, by manual or mechanical'means, be raised or lowered and in some cases, angularly disposed to permit treatment or the relaxing of a patient. Other orthopedic appliances, such as tilt beds are employed to place a patient in a substantially erect position. Out invention has embodied in one bed structure the advantages heretofore found separately in beds and in tilting tables. It has added certain other advantages which will be apparent from the description which follows:
Our invention is described in the accompanying drawingin which:
Figure 1 is a side view of the bed in a normal position ready for general use.
Figure 2 is a side view similar to Figure 1, except that the bed is tilted up a full 80 degrees.
Figure 3 is a back View of the bed of Figure 1.
Figure 4 is a top or plan view of only the tilting mechanism in a normal position.
Figure 5 is a sectional View of Figure 4 taken along line 55.
Figure 6 is a sectional view of Figure 4 taken along line 6- 6 to show the power unit of the tilting mechanism.
Figure 7 is a partial bottom view of the drive unit shown in Figure 6. v
Figure 8 is a view showing one of the many positions by using the tilting mechanism. This particular View shows how it is possible to raise the working height of the bed. 7
Figure 9 is a pictorial view showing one of several accessory rails and its use.
The following is a description of the construction and operation of the bed.
The bed is made up of a standard mattress 1, and the conventional hospital type articulated spring assembly 2, supported on a rectangular base frame 2, pivotally attached to a foot piece at pivots 5 and 6. Legs 31 and 4 on casters 39 are held in spaeed relationship byltie bars 7 to form the rigid frame constituting the foot piece. Tubular members 10 and 11 are rigidly secured to, brabkets 8 and 9, attached to tie bar 7. v Slidable within tubular members 10 and 11 are rods 12 and 13 w en" are rigidly 'secured at one end to brackets 14 and 15 attached to tie bars 16 and 17. I
Tie bars 16 aiid 17 and pivot rod 21 are membersof headboard assembly attached thereto by angles 18 and 19.
"ice
Pivotally attached to pivot rod 21 are bars 22 and 23, which are also pivotally mounted on pivot rod 24 of spring base frame 2. Bars 22 and 23, with cross bars 25 and 26, form a pivotable carriage which carries the tilting mechanism.
The tilting mechanism consists of the following.
Bearing blocks 27, 27', 28 and 28 carried on cross bars 25 and 26. Longitudinally slotted tubes 29 and 30 extend between the bearing blocks. Drive screws 34 are journalled in the bearing blocks and turn in slotted tubes 29 and 30. Drive screws 34 are driven by gears in gear box 33 to which are connected reversible motor 32. Motor 23 is mounted on support member 31 run-' ning between cross bars 25 and 26. Riding on each drive screw 34 is a threaded follower block 35, extending through the slots oftubes 29 and 30, and pivotally connected with push bars 36 and 37, the other end of each such bar being pivotally mounted on pivot rod 38 of spring base frame 2.
This is the basic construction of the bed. The operation is as follows.
The operator first locks the forward or rear caster 39, depending on available room and most convenient ar-' rangernent, then manipulates switch 40 which may be removably attached to head board 20 as shown. Cable 41 connects switch 40 to motor 32. I
To tilt spring base frame 2 toward a vertical position, reversible motor 32 is energized and threaded follower blocks 35, riding on the drive screws 34, push bars 36 and 37 against pivot bar 38. Since the distance between pivot rod 21 and pivot rod 24 is held constant by rigid bars 22 and 23, push bars 36 and 37 pivot on pivot rod 38, moving spring base frame 2 in an are about pivot rod 24. Since pivots 5 and 6 are a fixed distance from pivot rod 24, base frame 2 pushes legs 3 and 4 toward head board 20, causing telescoping of rod 12 in tubular member 10 and telescoping of rod 13 in tubular member 11, thus maintaining alignment between the foot and the head of the bed.
In order to maintain the balance of the bed when itis in vertical position, with a patient in it, a counterweight 42 is hung from tie bar 17 of the headboard assembly 20.
In order to obtain various positions of the bed, the tilting mechanism may be stopped anywhere in its cycle and by further adjustment of threaded shafts 43 and 44 of articulated spring assembly 2', as is done in hos pital beds presently in use, almost any position can be obtained. As an example, the entire level of the bed can be raised, as shown in Figure 8.
To prevent the mattress from falling off in the vertical position and to attach any of several attachments, such as the footboard 49, accessory bars 46 held to the spring frame by spacers 47 and screws 48 are provided. Belts 45' are used to hold the mattress securely in place.
Many changes in detail may be made in the structure shown without departing from the scope of this invention; Manual instead of motorized power may be used; casters may be dispensed with on either the foot piece legs or headboard assembly legs; structural changes may be made and other modifications employed. It' is not intended, therefore, to limit such scope by the description herein before given.
