Figs. 8 to 17 are side elevational, diagrammatic views upon a reduced scale as compared to Figs. 1, 2 and 7 showing ten of the typical positions into which the 'spring or bed bottom may be adjusted, Fig. 18 is a detail sectional view upon an enlarged scale showing the hinge connection between sections of the adjustable spring, and f Fig. 19 is a transverse sectional view on line 19-49 of Fig. 3.
Referring to Figs. 1, 2 and 7, a bed bottom or spring support or main frame A is carried on a rear bed upright support section B and a forward bed upright support section C.
Mounted upon the rectangular frame A is the center horizontalsection D, the foot section E with the end adjustment or auxiliary foot section F and the head section with the head adjustment or auxiliary head 'sectionl-l. The center section D is provided with an adjusting arrangement J, while the foot section E and the head section G are respectively providedwith the adjusting ar- I4 having the corner lock or hook members I5. The hook members I5 engage studs on the plates I! and I8 attached to the legs I9 and 20 of the upright members B and C. The upright members B and C have floor contacting rollers 2| and 22, with the connecting top bars 23 and 24 and the vertical members 24 and the horizontal members 25 (see Fig. 7).
The center section D is formed of the two short angle members 28 which are guided by the elevator piston rods 21 riding in the piston tubes or guides 28. As shown in Fig. 6, the top flange 29 of the angle member 26 is rigidly mounted on the reduced diameter portion 30 at the upper end of the rod 2'. which reduced diameter portion fits into an opening in the top flange 29. It will be noted that in the lowermost position asshown in Fig. 6, the top flange 29 of the angle member 26 abuts and rests upon the upper end 3| of the tube 28. The-vertical tube or guide 28 extends down- .wardly. through openings in the horizontal flanges .4I .and 33. The flange 33 extends inwardly from the panel member 34, which is riveted to the -vertical flange I3 of the main angle beam I0. The vertical flange35 extends downwardly inside of the tube 28 as shown best in Fig. 6. The tube 28 is fixed rigidly to the flanges I and 33 by the .Welding .36 and3'I.
'Pivotally connected to and extending downwardly from the vertical flange 38 of the angle ,member 2.6.is the bar 42. The bar42 is bentlinwardly and downwardly as indicated at 40so that z-the lower portion thereof will be insideof the ,zhorizontal'flange 4| of the main angle member I0 of the bed bottom. Its lower'end is pivotally ,'-connected at 43 tothe arm 44. The arm '44 is rigidly connected at 45 to the rotary cross tube 49. The cross tube 45 is rotatably mounted at its ends H 4'I in the web. member 34,. The tube 46 is also proyided with the arm 48 which is pivotally connected at 49 to the forwardly extending tube 50 form n pa tof. the opera ing m ha sm J for the central section D.
The operatingmechanisms J. K and L, being specificallyshown in Figs. 3 to 5, are generally thesame for the central section D, the foot sect on E'and h hea c i n G- The tube 50 .(see Fig. 7) at first inclines downwardly and then is bent so that it has a horizontal forward extension I5, which fits into the slides within the tube I6 (see Fi .3). The tube I9 is carried by the I l-shaped bracket I8 having the side legs I9 (see also Fig. the base 80 and the two horizontal flanges 8|. The flanges BI are riveted at 82 to the horizontal flange 8,3 of the crossbar member II.
Within the tube 15 is fitted the internally tapped bushing 84. The bushing 84 (see also Fig. 4) is fixed in position by the brazed drilled openings 85. The internal threaded opening 86 is lubricated through the transverse opening 81 which receives thegrease cup 88. Through the graphite cup 88 the bearing of the thread 89 on "the rod 90 in the sleeve 84 may be lubricated. The thread 89 is desirably a square acme thread.
"The rod 90 is provided with a sleeve'9l, which is fixed in position in the tube "I6 by the set screws 92. The sleeve 9| is also provided with an opening 93 to receive the graphite cup 94. The
4 I03 of the handle I04 is designed to be inserted in said recess WI. The handle I04 is made of flat stock and is bent substantially 90 at I05 to form a portion which fits into the recess WI.
The end of the handle bar I94 carries the rod or bolt I09 held in position by the lock nut and washer I01. The rod I09 extendsthrough the axial opening I08 in the wooden handle I09. The handle I09 is recessed at IIO to receive the head III of the bolt or rod I05. The flat portion I03 is slotted at I12 to receive the rod or pin II3.
When the handle I09 is elevated and pressed forwardly, the insert portion I02 will slide forward into the recess IOI and enable the rod 90 and the acme thread 89 to be turned in respect to the bushing 84 and the bearing sleeve 96. This will cause the tube to move inwardly or outwardly in respect tothe tube 16. When the adjustment is completed, by grasping the handle I09, the flat portion I02 may be pulled out of the recess 10!. The handle I09 may then be swung downwardly Out of the way in the stud II3 with the corner IM fitting into the recess H5 in the outer end H6 of the tube I5.
Referring again to Fig. '7, the foot section E is composed of two angle sections I25, which are hingedly connected at I23 (see also Fig. 18) to the central section D. As shown the hinge bar .350 is rigidly riveted at 35I to the vertical flangelzl of the angle sections I25. At 353, the bar 350 is pivotally mounted on the vertical flange 38 of the angle member 26. Upon hinging movement, the
bar 350 will move in the slot 354 in the top flange 29 of the angle member 23.
Depending downwardly from the vertical flanges I2'I are the bars I28, which turn inwardly and downwardly at I29. The lower portions I30 of the bars 28 are pivotally connected at I3I to the arms I32 and I34, which are mounted upon the rotary tubes I33. The ends of the tube I33 are ivotally mounted at I35 in the flange members '35 of the side plates 340i the main frame.
Extending upwardly from the lever or arm I32 is the arm I36. To the arm I36 at I31 is pivotally connected the flattened upturned position I38 of the tubular member I39. The tubular member I39 fits inside of the tubularmember I49 andis actuated by the manual operating member .I4I. These members I39, I40 and I4I may be of the same construction and operate in the manner already indicated in the Fig. 3.
The foot section E has a U-shaped auxiliary frame F pivotally connected to it at I42. The frame F has the side members I43 and the end The members I25 of the foot section E and the side members I43 of the auxiliary frame F have depending ears I36 and I4] with rollers I43 and I49 to support structures E and F on the horizontal flange 4! of the side frame members I0.
Extending downwardly from the horizontal flanges I50 of the side members I43 of the U-frame F are the rack members I5I having putturned connections I52 at their upper ends to the vertical flanges I58. The rack members; t5]
are connected by a cross bar I53 and the roller or slide pins 15,which ride on-the flanges I55 extending inwardly from the angle members I58 riveted at I 51 to the vertical flanges I 3 of the main frame members I0. p
Also extending downwardly from the vertical flanges I50 of the side members I43 of the frame -F is the U-shaped pawl member 158 pivotally connected at I59 to the flanges I50 and having base section I 60 which engagesthe teeth -I6I" on thedepending rack members I-5I. "By adjusting f 'aeeaave F the transverse horizontal base rod I60 'in the' 'varlous teeth ornotc'hes' I6 I, the frame F may be kept in the same plane "as the frame Eor inlthe plane inclined upwardly or downwardly from the frame -E in the direction of. the feet of the patient. J :Simila'rly by the'relative adjustment of the mechanisms J and K the frame E may be caused to incline upwardly from the frameD or tobe in the same plane as the frame D or incline. down- .wardly from. the frame D.
The head frame G'consisting of the sidechannel members I is. pivotally connected at .I'l6 to the center section D. The side members I15 are connected at the rear of 'thestructure by the crossmemberiill. Pivotally mounted at ,I18on the vertical flanges I'I 9 of the angle members I15 are the ears I80 of theside angle members --I8I of the adjustable U-frame or auxiliary head ;;,frame H. The members I8I are connected. at
their rear ends by the cross bar I82 v vhich has,
ti ons I85 which engage the horizontal flange I86 of the member I44.
Referring to the section H (see Fig. '7), there aresprofvided the angle members I81, attached. to the side beams .18 I. .The downwardly projecting ears I89 of the members I81 carry the depending arms I89 which have reduced diameter stud portions I90 to fit into the series of adjustment holes I9I in the top flange I92 of the side members I79 of the structure G.
Elevating the section Gare the arms I93 having the o'utturnedv portions I94 carrying the rollers I95. Therollers I95 ride under the top flanges I92 inside of the angle members I19. The arms I 93 at their lower ends I96 are connected to the rods I91, which are rotatably mounted at their ends I98 in the apron flanges 35. Riveted to the levers I93 at I99 are the arms 200. To the upper ends I of the arms 200 are pivotally connected the flattened ends 202 of the tube 203. The tube 203 fits into and slides within the tube 204 of the adjustment arrangement L.
By the rotation of the actuator 205, it is possible to incline the head section G upwardly from the structure D or position it in the same plane as the structure D or to incline it downwardly from the section D.
Carried by the sections D, E, F, G and H is the bed bottom or mattress support consisting of the longitudinal wires 420 with the end connecting coil springs 4 I 8 and the crossing lateral wires 42I with the connecting coil springs 4 I 9.
Extending between the side members I43 of the auxiliary frame F, the side members I of the main foot frame E, the side members I15 of the main head frame G and the side members I8I of the auxiliary head frame H are the cross braces or the tubular members 400, 402 and 403.
In Figs. 1 to 1'7 are shown ten of the various adjustments which may most readily be made. In all of these adjustments the mattress may be considered as on the five section adjustable frame DEFGH, held in position by the stops I84 at the foot of the bed and I83 at the head of the bed. The adjustable frame D-E-FG-H may initially be considered to be in the position shown in Fig. 2. The central horizontal section D is first elevated to the desired height by turning the lever I04 at the front of the bed.
{'6 Assuming the lever I4I (see Fig. '3) is in'down position with the nose .or corner II4 fitting into the opening II5,.with the flat portion I03 in the slot 4 I 6 and the pin I I3 in the left end of the slot H2, the handle MI is elevated and pushed forward with portion I02 fitting into the slot I00. Then the handle I04 is turned, causing therod and thread 89 to turn in the sleeve 84 moving the tube 75. The tube I5 will turn the arm 48 which in turn will rotate the rod 46 .andthe arm '44. The arm acting through the pivotally connected link 42 will elevate the central horizontal section D which will always move parallelly to the main frame A by reason of the coaction of the guide rods 21 fitting in the guide tubes 20.
When the central section D has been elevated to the desired position, the handle I4I may be withdrawn and; dropped in back of the frame .C; with the portion I03 passing into the slot 4I5.
- the-tube I33,- and the link I30 to elevatenor depress the section Eon the hinge I26. The hanj dle 205 will move the tube 203, the arm 200 and the lever I93 to raise or lower the main headsecto the holes I9I, while the auxiliary foot section F may be raised or lowered by engagement of the rod I00 with theratchet IBI. ;'Ihe r atchet bars I5I will always depend from the frame-E sincetheir rollers will slide on the angle guide members I55. j q j 3 In Figs. 8 to 17 are shown various adjustments which may bereadily made, theseadjustments respectively being lowposition in Fig. 8, bronchoscopic or eye position in Fig. 9, high cardiac position in Fig. 10, spinal hyper-extension position in Fig. 11, Trendelenburg position in Fig. 13, Fowler or drainage position in Fig. 14, bed pan position in Fig. 16 and reading or eating position in Fig. 1'7.
In Figs. 10, 12 and 17 an overhead table may be readily employed. In no position is there an abrupt transverse break across the back of the patient and in all positions the patient will be given a feeling of maximum security. The horizontal position of the central section D in all adjustments will give anatomically correct support and positioning and maximum comfort. When the patient is in any treatment position, he or she may then be readily moved to reading, eating or bed pan positions without great exertion on the part of the nurse or attendant and without discomfort or injury to the patient or feeling of unsecurity on the part of the patient.
The rollers I48 and I49 of the foot sections E and F, as well as roller I95 of the head section G will assure smoother and noisless operation with less friction. The roller I95 for example may be 2% in diameter. The hinge I26 of Fig. 18 will assure enhanced strength to the hinge connections between the frames D, E, F and G and enable better spacing of said frames. The diagonal braces 422 increase the strength of the corners of the section G. The longitudinal angle 4I'I will strengthen the elevating mechanism J I for the central section D.
All corners and edges are rounded to prevent tearing of the bed clothing and injury to nurses and patients. The folding handles I04, I M and 204 can only fold vertically downwardly between racers-ma "zthe'xverticalibars ofthe footzframelc, and Willnot strike :ormar theffoot .frame, because of :the "coaction between 'the .bars [03 and the slots M16. Thezhand grips 109 are easyito remove and quiet and nonbindingin operation.
The 'corner hook plates 14 hold the bed and spring 'firm and rigid and permit moving of patient on the bed .from' room to room without danger of thespring'becomingloose. In'operation 12 lbs. pressure applied'to the ends of the handles 100, [41 and 1205 vwill'readily enable "lifting and movement of a 200lb. person.
As many changes could be made in the above -'adjustable hospital bed and many apparently widely difierent embodiments of this invention could be made-without departing from the scope of the claims, it is intended that'all matter-containedin the above description or shown in the accompanying drawings shall be interpreted as illustrative-and not in a limiting sense.
