MATTRESS WITH ADJUSTABLE BACK LEG SUPPORT.
Application led J une 1, 1927, Serial No.
Mattresses intended for sick persons require an adjustable back-rest and adjustable leg-supports. These supports and the backrest may be adjusted independently from one another, but in most cases another person is required therefor, as the sick person himself or herself is only exceptionally in the position lto effect the adjustment,especially4 only the back-rest need be adjusted, whereas the leg-supports must remain in their normal flat position. This is' impossible where the leg-supports are coupled with the back-rest and can be adjusted or Ire-adjusted only together with it.
The present invention permits to adjust or re-adjust the back-rest and the leg-supports together, as well as independently one from the other, and this effect is rendered possible by the provision `of a coupling between said members and of another coupling inserted between the leg supports and the mattress frame. Owing to theshafts required for the twofold adjustability being located in close proximity to one another, onl one actuating lever or arm is required which may be attached at will to the one or the other shaft whereby the sick person is enabled to adjust either the back-rest or the leg-supports separately or 'both together, just as desired or necessary in the individual case. The operatin lever or arm can also y any attendant if the sick person himself or herself must remain lying in a prescribed position.
If both shafts extend across the whole breadth of the mattress, they can be turned from either end. The adjustability of the back-rest and' of the leg-supports can be improved still more by givin the back-rest, the leg-supports and the mi dle frame located between them equal lengths v'so that if the back-rest and the leg-supports are to be adjusted or re-adjusted at a time the weight of the one balances the weight of the other in that the back-rest is turned ,upwardly, the
be4 actuated, of course,
195,823, and in Germany June 10, 1926.
leg-supports, however, are turned downwardly.
v The invention is illustrated diagrammatically and by way of example on the accompanyinr drawing on which FigureA 1 is a sideview ofb a bedstead equipped with a mattress designed according to this invention, the mattress being shown in its normal state; and Figs. 2, '3, 4 and 5 show the middle part ofthe mattress, also drawn to an enlarged scale, Fig. 2 corresponding to Fig. 1, as regards the position of the movable members, and Figures 3, 4 and 5 showing the movable members in their various possible positions, all as fully described hereinafter.
On the drawing, a denotes the stationary horizontal main frame of the bedstead, and b the middle part of an elastic frame which is firmly connected with the frame a by pivots d and '0. c denotes the back-rest and n the leg-supports. The back-rest is turnable on the pivots d and firmly connected with two downwardly directed levers e. The leg-supports are turnable on the pivots 0 and also firmly connected with downwardly directed levers. m. These levers and the leg-supports form an acute angle on each side of the bedstead, whereas the levers e andthe back-rest form obtuse angles.
The frame supports also two horizontal transverse shafts f and i. The shaft f is provided with arms g connected with the levers e by rods h, the arrangement being such that if the parts are in the position shown in Figs. 1 and 2 and the shaft f is turned in clockwise direction the rods h and the levers e are moved to the left and the back-rest c is turned from its position of rest (Figs. 1 and 2) into the working position shown in Fig. 3. The arms g and the rods h are connected with each other by pivots g', and .these pivots serve also as means for connecting the arms g with other rods p, the other endsof which are provided with slots g engaged by pins m secured to the free ends of thev levers tm axed to the leg-rests n. When these parts are in their position of rest, as in Figs. 1 and 2, the pins lm are located in the 'left hand end of the slots g. These pins serve also as means for connecting the of which are connected with arms k affixed to 4,the shaft i. These arms are provided with cogged sectors c having ratchet teeth, and similar cogged sectors are connected with the arms g of the sha f. The cogged seclevers m with rods Z, the other end s tors g co-operate with a pawl r and thev cogged sectors k co-operate with a pawl s. This pawl can be thrown into, and out of, gear by means of a grip u, and the pawl r can be 4thrown into, and out of, gear by means of a grip t. Although I have shown ratchetteeth on the sectors g and k which can be checked only in one direction, I wish it be understood that the gearings or their equivalents may be of a kind permitting checking in both directions.
If the back-rest, aswell as the leg-supports are to be adjusted or re-adjusted, both pawls r and s are thrown out of engagement with the ratchet-wheels g and c by nieans of the grips t and u, and a lever z" shown in dotted lines in Fig. 5 is put on a square extension provided at only one end, or at both ends, of the shaft f, as well as of the shaft z'. In
Fig. 5 the lever z" is applied to the shaft z',
but if the back-rest and the leg-supports are to be moved at a time, the lever i', is applied to the shaft f, and if then the lever z" is turned in `clockwise direction (as regards the ures, especially Figs. 2 and 3),`the back-regt will be lifted from the position Fig. 2 into the position Fig. 3. The leg-supports n folv low' automatically, in that, besides the rods L, also the rods p have been moved by the arms g', the levers m of the leg-supports being then no longerretained in the position Fig. 2, but being turned by the weight of the leg-supports which swing down' from the position Fig. 2 into the position Fig. 3.
' When the parts have arrived in their other positions, as just described, they are locked e therein by the pawl r which is turned into engagement wth the teethg by the grip t.
If the leg-supports are not `to be actuated slmultaneously with the backest, the pawl s is caused to engage the teeth 7c', as in Fig. 4,..
whereby the members c and Z are locked, in consequence whereof the leg-supports cannot give way, but remain in their horizontal p0- sition, as appears clearly from Fig. 4. And if, finally, only the leg-supports are to be lifted, without simultaneous lifting of the back-rest, this latter is locked in its position, in that the pawl r is inserted into the teeth g by the grip t, and the lever z" is attached to the shaft z', as in. Fig. 5. The leg-su ports may now be adjusted as required and lbcked in the respective position by the pawl s.
I claim:
A mattress, comprising, in combination, a mattress frame, the middle portion of which is located immovably in said mattress frame, an adjustable backrest hinged to one end of said middle-frame, adjustable leg-supports hinged to the other end of said middle-frame,
two transverse shafts held by the mattress v frame and extending from one side to the other side of the same, a lever adapted to be attached to any end of any of said shafts and adapted to be moved by the person confined to the bed provided with the said mattress, levers and rods connecting one of said shafts to said back-rest as well'as to said ports, other levers and rods connecting the other of said shafts to said leg-supports only and on the same pivots with said first named rods, and slots in the ends of the said rods of the Erst mentioned shaft engaging said pivots, substantially as described.
In testimony whereof I affix my signature.
OTTO HOLTKAMP.
