The ymattress supporting frame compises a plu-'- Ialityv of sections' elCh haVing a bOttm `Ia'ortitlh Zliyii WlliCh-theli'iatti'ess 48 Tests, al-lidllpwardly -prjectififg sde flanges 2l,- b'tweei the'sides` O'f wheh the mattress is `plsitiolfled. The `Side flanges 2l are in the ferm of dewnwaidlir einen` ing channels, in "which the fiarli `rails i9 4elfe received.
The mattreSsSupIOrtmg file'sectins include the heeely rest section it, tite'intemeeiete thigh" sectieii B; and the f'ct rest section G; Th' foot rest section C is connected to the thigh section B by aiiyinter'nediate section Dl'ad a #air ef hinges 22 and The I-Itei'hiediate Stn D" coin-prises aai-rf of inverted channels 214 each connected to a iiange 2| f the thigh section B` f 'by ay hinge 22 4and tfth leg section 'C by :a hinge 23. The legs of the Channels 2F11 `are trapez'i'dall outliie. A transverse rod vZ5, on` which is` hinged a 'pair 0i flaps 2'6 `and 327, has its eids'l meutea in the ehermeis 24. Tneedgeeef sees 12s, zi esente tite edges that ere "negeer 3 to the rod 25, overlap and rest upon the upper surfaces of the ybottom members 28 of the frame sections B and C respectively, and slide upon these surf-aces.
The back rest A is adapted to be elevated. by suitable lift mechanism which is not shown but is similar to the lift mechanism for the thigh section B, which lift mechanismincludes a pair of arms 28 hinged at 29 to the stationary frame Y I1 and having, at their ends `opposite the hinge 29, rollers 30 which engage the under surface of` the bottom member 20 of the thigh section B.
4 This gap is of suflicient width so that there is no danger of any member that could be damaged, being caught therein. The gap is covered by a. flexible sheet metal leaf 45 the edges of which are hinged to the back rest A and thigh section B at 46 and 41 respectively. l
When the back rest Afand thigh section B are in their lowered positions, the leaf 45 will be stretched in a flat plane as indicated in dotted lines. When the back rest A and thigh section B are in their positions of normal elevation shown The arms 28 normally lie substantially below the plane of the sub frame I9. They are pivoted'at 3l to push rods 32 through Vwhich elevating movement is transmitted.
. The thigh section B, as it is elevated, carries with it the leg rest C. The weight of the leg rest C, imposed upon the hinges 23, tends to rotate the intermediate section D downwardly around the axis of the hinges 22. Such downward movement of the section D may be prevented by a latch 33 which is pivoted at 34 to a side flange 2l of the thigh section B. The latch 33 is adapted to project into a slot 35 in the bottom memberZ to engage the edge of the flap 26. With the flap thus engagechit is impossible for the intermediate section 24 to swing downwardly about the hinges-22. Instead, it is held in a position projecting in alignment with the side 1 flanges 2l of the thigh section B as shown in Fig. 2. Y Y Y The latch 33 may be provided with a lip 36 adapted to. project Vover the upper surface of the flap 26 and prevent any possibility of the nap 26 slipping oi the end of the latch 33 when compression is applied between Ythe two members. The latch 33 is also provided with a lever 3,1 which'extends upwardly and is provided with a handle 38 at its upper end. When the lever 31 is moved toward the head rest A, the latch 33 will be liftedabove the flap 26, permitting the latter to slide beneath the latch and thereby allowing the intermediate section YD to tilt downwardly about the hinge 22 toa position of alignment with foot rest section C as shown in Fig. 3. In this position, a pair of lugs 39 and 40 on the ends of the .side plates of the channel 24, and the anges 2| of the leg rest C will engage to provide a stop action which prevents therhinge 23 breaking downwardly and thus supports the foot rest C in alignment with the connecting section D as shown in Fig. 3.
It may now be noted that when the parts are in the position shown in Fig. 2, the flap 26 will cover a gap existing between the end of the bottom wall 20 of the thigh section B and. the hinge 25, while in the position of the parts shown in Fig. 3, the flap 21 will cover a gap existing between the hinge 25 and the end of the bottom wall 20 of the leg rest C. In addition to its primary function of covering the gap, the flap 26 alsoserves as part of the means for latching the connecting section D in alignment with the thigh section B.
ing downwardly. (See Fig. 6.) The lugs 39 and 4I)y are similar to the lugs 4I and 42.
The thigh section B and back rest A are hinged to each other and to the side rails I9 of the sub frame I8 by means of hinges 43. The ends of the flanges 2ll and Ybottom walls 28 of the section A and B adjacent to hinge 43 are cut away as at 44 toleave a gap between such ends at all times.
in Fig. 2, ltheplate 45 will assume a broad curve coaxial with the axis of natural flexing of the mattress 48, which is of sponge rubber. The plate 45 is of spring material, and therefore will flex with a substantially uniform curvature.
In order to secure the proper amount of flexure of the plate 45 froma flat condition to a properly curved condition, the location of the axis of the hinge 43 (its spacing above the common plane of the bottom walls 2Ilwhen the latter are horizontal) is correlated to the spacing of the hinges 46 and 41 so that only a moderate amount of foreshorteningof the distance between the hinges 46 and 41 will occur as the back rest and thigh section swing upwardly from their horizontal positions to their elevated positions. To this end, the axis of the hinges 43 is located intermediate the common plane of the hingesr46, 41 in their lowered positions and the common plane of the pivots 46, 41 in their elevated positions, and is somewhat'closer to the former plane than Yto the latter. Also, there is a lost motion` connection in the hinge 46 which permits the hinges 46 and 41 to spread as they move upwardly from the lower of the two aforesaid planes to a common plane for all three of the hinge axes 46, 41, 43. The lost motion connection may be effected by elongating one setof the hinge loops -comprising theY tions, while the lower walls 5I) are cut away at 5I to permit Veach hinge to breakV upwardly except when rigidified by a sleeve 52 which may be slid longitudinally over either of the hinges.
