Patented Aug. 16, 1938 UNITED STATES PATENT OFFIQE FOLDING HOSPITAL: STOOL Morton T. Dowdy, Bakersfield, Calif.
Application March 16, 1937, Serial No. 131,226
This invention relates to bed attachments, such 3 Claims.
as are used in hospitals and particularly to a folding stool adapted to be detachably engaged with the bed rail of a hospital bed, which stool is normally in a folded-up position, but is so constructed that it may be readily lowered so as to provide a stool supported firmly upon the ground and at a convenient height from the top of the bed.
Another object is to provide a supporting frame attachable to the side of a bed and which has a stool or seat portion pivoted thereto so that it may be turned from a vertical to a horizontal position, provide legs for the outer end of this seat or stool, and provide means which will positively shift these legs into a vertical supporting position as the seat is turned downward to its horizontal position and will positively swing these legs back into the seat or parallel thereto when the stool is turned upward against the bed and into a vertical position.
Other objects will appear in the course of the following description.
My invention is illustrated in the accompanying drawing wherein: I
Figure 1 is a perspective view of one embodiment of my invention.
Figure 2 is a vertical sectional view through the chair constructed as in Figure 1,
Figure 2 is a fragmentary section on the same line as Figure 2 but showing the legs folded up. Figure 3 is a fragmentary vertical section through the seat of the chair showing a modification of the structure shown in Figure 2.
Figure 4 is a fragmentary section through the seat of the chair showing another modification of the structure.
Figure 5 is a fragmentary section on the same lines as Figure 2, but showing a still further modification of my invention.
Referring to the drawing, it will be seen that I have provided a frame consisting of the vertical members ill and the cross-brace l i, which is adapted to be engaged detachably with the side of a bed, as for instance, with one of the side rails of the bed. The members it] are cut away, as at l2, so as to receive the side rail of the bed, and a latch I3 is pivoted upon the cross-brace It, so that it may be turned up on the inside of the bed rail to thus detachably lock the members It] in engagement with the bed rail. These members In with the cross-brace II and the latch l3 constitute in effect the back of a chair and a support- Disposed between the lower ends of the members II is a seat 14 which includes the ing frame.
side bars Passing through the lower ends of the members Ill, through the side bars and beneath the seat i4, is a shaft it, which shaft is fast in themembers ill and does not rotate. The side bars are, however, rotatable upon the shaft. Disposed at the free 5 end of the seat is a second shaft I? which is free to'rotate in these side members l5 and rigidly connected to this shaft for oscillation therewith are the forward legs I8.
Secured rigidly to the shaft I6 is an arm I9 and secured rigidly to the shaft l l is a toothed sector or segment 20. Pivotally connected to the arm 59 is a rod 21! which at its forward end is formed with rack teeth 22. These teeth engage with the teeth of the segment 20. As illustrated, the rod 2| is formed of a flat piece of metal, the rear portion of which is vertical, and is thentwisted about its middle so as to provide a horizontal portion which carries the rack teeth 22. Beneath the seat l4 is'a transverse brace 23 which is cut away 20 to permit the reciprocation of the rod 2l. The forward end of the seat I4 is formed with a transverse brace or frame member 24 and this is cut away at its middle, as at 25, to permit the reciprocation of the rod 23. This transversely extending frame member 24 is beveled at 26 and constitutes a stop against which the legs !8 bear when the legs are forced downward to an approXimately vertical position. It will be noted that the legs are not truly vertical but that they extend downward and forward so that the upper edges of the legs bear against these inclined faces 26 and thus the seat is fully supported upon the forward legs and at the same time these forward legs cannot move inward.
The frame formed of members III and I constitutes the back of the seat. This frame might be padded upon its forward face or otherwise formed; Obviously the seat It might be cushioned or padded and some other means of attachment might be used whereby the back frame of the seat may be attached to the bed and held detachably engaged therewith.
The primary object of my invention is to provide a seat or stool of this character which is normally supported in a vertical position but which when the seat is given a slight shove, will fall downward to carry the seat to a horizontal position and in doing so, the legs l8. will be positively forced to a position, as shown in Figure 2,
to thus positively and solidly support the seat.
When the patient wishes to get out of bed, he, or an attendant, simply pushes the top of the folded seat forward and downward and upon the downward movement of the seat, the folded legs l8 are positively forced to their vertical supporting position by means of the rod 2|. This makes it certain that the front legs will drop so as to stand vertically and makes it certain that the legs l8 cannot be moved rearward, and thus the patient, when he gets out of bed is sure to have an absolutely firm stool upon which he may step in getting out upon the floor, or upon which he may sit. It is very essential to the patient, particularly if he is weak and nervous, that he shall be certain of the strength and solidity of what he is to stand on. The seat of an ordinary chair is too high and besides that, the chair may tip. My device cannot tip in any direction because it is rigidly held to the bed and this the patient knows, The legs cannot fold back because they are positively held in their vertical position so long as the seat is in a horizontal position. The chair is also extremely convenient for doctors, nurses or visitors and may also be used for resting articles In Figure 2 I have shown the stool of Figure 2 in a folded position detached from the bed.
In Figure 3, I have illustrated a modified form of the arm 19. This modified form is designated l9. This arm is not pivoted to the connecting rod but is formed as a toothed segment and the rod 2| is shown as having teeth engaging the segment. This form of arm l9 may be used in place of the arm I9. Vice versa, the segment gear 20 may be replaced by an arm 20 mounted upon the shaft I1 and to which the forward end of the rod 2| is pivoted.
In Figure 4, Ihave illustrated another modification in which both of the shafts l6 and I! are provided with outwardly extending arms, the arm of the shaft I 6 being designated [9, the arm of the shaft I! being designated 20 A connecting rod 2 l connects these arms. Otherwise than this, the construction is the same as that shown in Figure 2, but here too, it will be seen that when the seat is turned upward to its vertical position, the legs l8 will swing to a folded position and when the seat is turned down to its horizontal position, the legs It! will swing outward, then downward to the position shown in Figure 4.
In Figure 5, I have illustrated still another modification in which the back I is extended downward below the seat, as at I O The legs I8 are pivoted upon the sides I of the seat, as at I8 and a connecting rod 2 l is used between the back of the seat and each of the legs. With .this construction also, as the seat is turned upward upon its pivot 14*, the legs will be drawn inward into folded position, and as the seat is swung downward, the legs will swing outward and downward, bearing against the cross-bar 24 and supporting the stool firmly in its unfolded position.
While I have illustrated certain details of construction and arrangement of parts, I do not wish to be limited thereto, as many changes in these details might be made without departing from the spirit of the invention as defined in the appended claims.
What is claimed is:-
1. A stool attachment for beds, including vertically disposed connected supporting members constituting the back of the stool and having means whereby they may be clamped upon a bed rail, a seat, a shaft extending loosely through and rotatable in the rear end of the seat and at its ends rigidly engaged with the vertical supporting members, a rotatable second shaft rotatably mounted in the forward end of the seat, a pair of legs rigidly engaged with the second shaft, a connecting rod disposed beneath the seat and extending over the two shafts, means on the first named shaft engaging the connecting rod to shift it rearward as the seat is turned from a vertical into a horizontal position, and means operatively connecting the connecting rod with the second named shaft to cause the rotation of the second named shaft as the seat is turned to a horizontal position in such direction as to carry the legs into an approximately vertical position.
