`movable leg members and the adjusting means therefor associated with Ithe hollow corner posts'.

In the drawings wherein for the purposeof illustration is shown the preferred emsections 17 and 18 are separated at the rear end of the bed, and the spring bottom 19 has its rear part formed of two sections separated from Aeach other at the longitudinal centerv thereof, s o that one of the foot sections wlth its spring bottom can be adjusted independently of the other foot section and its spring bottom, and it will also be iseen that the foot part of the bed bottom composed of. the two -v Y bodiment of my inventiomthe 'numeral 1 .designates generally my improved adjustable bed, the same comprising the head and foot frames 2 and`3, respectively. Theseframes are connected together in spaced relation through the medium of the channel shaped side rails 4. The head and foot frames may be of any desired shape and the side rails are secured tothe-corner posts of the respectlve frames in any appropriate manner.

Each of the corner posts of both the head and foot frames are capable of being 'lengthened'or shortened, and to this end the notched the opposite side of the stationary s'eat .sec-

shank 6 formedon the upper end of the leg 7 is slidably disposed within the lower open end of the hollow corner post. A -loor engaging caster 8 `is carried by the lower end of the leg member 7.

A llever 9 is pivotally mounted-on one side of the lower end portion of the tubular colf ner post for vertical swinging movement and carried by this lever is a spring pressedlinger 10 that is adapted for engagement with the shoulders of the notches formed in the shank 6 to effect the upward movement ofA the corner post with respect to the' leg member when the lever is swung upwardly. A spring pressedlatch 11 is arran ed on the other side of the lower portion o the tubul lar corner post and extends through an opening formed in the corner post also for engagement with the shoulders of the notches to prevent downward sliding movement of the tubular corner post as more clearly disclosed in Figure 18. In this manner either the head `'or foot frame of the bed may be vertically adjusted to meet certain conditions.

Each of the channel shaped side rails is' formed in the bottom thereof with teeth 12 adjacent the head frame engaging end thereof. Similar teeth 13 are arranged in the' other end or each channel shaped side rail and the purpose of this construction will be presently apparent.

The bed bottom that is constructed of ilat material comprises the head section 14, the seat section '15, the thigh section 16, and the complementary independent foot sections 17 and 18 respect1vely. Each of these sections is formed on its under side with spaced reinforcing ribs 1. A'ilexible sprinv bottom 19 is provided for each section and transverse 'steel bands 20 areassociated with the seat and thigh sections. As shown in Figure 1, these sections 17 and 18 is. of less width than the' bed frame so that it can pass between the rear ends of the side rails and the' footpart of said bed frame. v v

The' seat section 15 is xedly secured to the intermediate portion' of the channeled side rails 4asat 15V in Figure-9.

The inner end of the head section 14 is tion 15 as at 22- Thus the thigh section 16 isv also capable of vertical swinging-movement.

The independent foot sections 17 and 18 i are hingedly secured at their inner ends to the respective ends of the thigh sections as at 23 for vertical swinging 1novement. head, seat and thigh sections normally are adapted to lie ilatupon the upper edges of the channel shaped' side rails o the bed, the .foot sections'are confined between the side rails and normally are supported in al1ori zontal position in the same plane with the other sections o f the bedbottom, by the blocks or buttons 30 carried by the springs 30', the buttons or blocks 30 engagingparts purpose to be presently The 'of the side railsof the bed frame with the foot sections 17 and 18 resting 011 the buttons. By v' pushing these buttons 30 outwardly against the action of the spring 304 the foot sections 17 and 18 canbe lowered to the dotted line position shown in Figure 2.

Attention is directed now to Figure `11l wherein there is disclosed a means for securing the. hinged foot sections together at the rear-end of the bed and to this end there is provided a sliding bolt 24 that is carried by the rear end portion of the foot section 17. The free end of the bolt 24 is adapted to -slide through registering I enings formed in the adjacent inner sidesiof the footsections. An actuating handle 25 is associated with the sliding bolt, and this handle is operable within a slot 26 formed in the rear end portion of the section 17 y l When the parts are arranged as shown in Figure 11, the foot sections are locked 'toether :for movement in unison. However, retracting the bolt so that the free end ereof is-dlsengaged from the foot section `vious'from the construction .illustrated in Figure 1`.

Suitable arms 27 are pivotally attached at their forward *ends to the respective sides of the head section 14. The lower free ends of these arms are adapted for cooperation' with theiteeth 12 arranged in the adjacent ends of the channel shaped side rails whereby to support the head section 14 in any angularly adjusted position as indicated by the dotted lines in Figure 2. When the head section 14 is disposed in a horizontal plane, thev arms 27 will be confined Within the respective channel shaped side rails.

A rod 28 "extends between the opposite arms 27 and the upper edges. of the opposite sides of the side rails are notchedl as at 29 as shown in Fig. 13 for receiving the rod 28 so that the'head section will rest on the side rails of the bed. This rod facilitatesadjustment of the arms 27.

Av pair of arms 31 are each formed with a perforation at one end to receive a part of the pin used at each connection 23 provided between the thigh and foot sections, and these arms are capable of vertical swinging movement. The free ends thereof are adapted to co-operate withthe teeth 13 formed in the adjacent ends of the channel'shaped side rails for the purpose o f maintaining the thigh'section 16`in any angularly adjusted position.

Each of the arms 31 is furthermore formed with a series of notches 32 adjacent the free' end thereof with which `cooperates the laterally disposed portions 33 of a substantially U-shaped supporting member 34 that ex-V tends transversely across' the foot sections, the upper end of the arms of this U-shaped member being directed inwardly to form pintles 35 that engage within suitable openings provided therefor in apertured lugs 36 associated with the respective'foot sections, and

Len

when this U-shaped unit 34 is employed, the foot sections 17 and 18 are both secured together and held in a raised position.

A general cross rod 37 connects the arms or prop rods 31 together-and 'as is clearly shown in Figures .5 and 16 each end of the cross rod 37 is threaded andv is disposed through an opening formed in the respective arm 31. Suitable knurled nuts 38 are threaded on the cross rod for engagement with the opposite sides of each arm or prop or rod 31. The inner iange of each of the side members 4 -is cut away at therear part of the side member, as shown at 4.in Figures 7 and 16 to form rests for this rod 37 -when the foot Y section not to be raised.

lsections 17 and 18 are in lowered horizontal positions.

When it is desired to maintain only one of the foot sections in a raised position, the general cross rod 37 as well as the U-shaped suppins are released from an arm 31 so that the arm can lie in the side member as shown in Figure 7, as the arm 31 is not used for foot Then across rod suchV as is shown at 39 is substituted for'the general cross rod 37. AThe rod 39 is formed vporting member 34 isl removed and the pivot at its central portion with three spaced openf ings 40 and the ends of this rod are threaded to accommodate nuts similar to the ones associated with the ends of the general cross rod 37.

A yoke member 41 has its free ends removably fitted to any pair of openings 40, de.- pending upon which foot section is to'be elevated. An adjustable prop unit 42 isopera-v tively connected at Aits lower end tothe yoke member 41'while the vupper end thereof detachably engages with `and supports the bed bottom 19 of the elevated foot section adjacent the juncture of the foot section with the thigh section 16 as `more...clearly shown in Figures 6, 7 and 14 of the drawings. AnV

additionaladjustable prop unit 43 is piv-l otally connected at its lower end to the lower portion of rear prop unit 42 as at 44, and the upper end of the prop unit 43 supports the rear end of the elevated foot section as at 45. One'of the arms 31 is left attached to the section 16, according to which of. the foot sections 17 and 18 is to be raised, as shown in Figure 6.

The foot sections are4 also capable of being disposed downwardly in an angular position when the supporting means 30 thereforis disengaged, and said foot sections are swungdownwardly to the position shown in dotted lines in VFigure 2." Y

The invention further comprehends the provision of detachable side guards 46 that are to be used when the bed is converted into a crib, and the upper and lower rails of each side guard are formed at their respective ends With curved attachingV brackets shown at 47 in Figure 17.

These curved brackets 47 engage vwith the respective corner posts of the head and foot frames 2 and 3, respectively, and suitable fascrib. The bed bottom is of such'construction as to permit the occupants to l*assume a recumbent position or a sittingposture.

The various sections of the bed bottom may i be adjusted tov comfortably support the various parts of the body of the patient or ocupant,`and the parts are so arranged vas to permit ready and easy adjustment.

A bed of this character will atall times be positive and eilicient in carrying out thepurposes for'whic'h it is designed, and can fur- -thermore be constructed ata very low cost,

. yet be vstrong and durable.

While I have shown the preferred embodimentof my invention it is to be understood that minor changes in the size, shape andarrangement of parts may be resortedto without departing from the spirit of the invention and the scope ofthe ap nded claims:

Having thus describedhe invention, what I claim as new and desire to secure by Letters Patentisz Y l' Y Y v 1.
