Application filed May 20,

This invention relates to an improved portable structure or cot, adapted especially for use in connection with ambulance service, or in hospital or mortuary establishments, and an object of the invention is the provision of a device of this character wherein the main frame thereof is removable from an associated portable base, in order that the main frame may be utilized in the capacity of a stretcher for the purpose of lifting or carrying a patient from place to place independently of the base but to admit of the use of the latter in supporting the frame when conditions permit this to be done.

Another object of the invention provides in constructing the frame to include a plurality of hinged or pivotally related sections by which the latter may be relatively adjusted to assume operating positions best adapted for the support and requirements of the patient, and in providing the sections of the frames with means for retaining said sections in thein relative positions of adjustment.

With these and other objects in View, as will appear as the description proceeds, the invention consists in the novel features of construction, combinations of elements and arrangements of parts hereinafter to be fully described and pointed out in the appended claims.

In the accompanying drawing:

Figure 1 is a perspective view of the im proved cot comprising the present invention,

Figure 2 is a top plan view thereof,

Figure 3 is a vertical longitudinal sectional View,

Figure 4: is a transverse vertical sectional view on the line 4 1 of Figure 3,

hating the body section, the numeral 3 the head section, the numeral 4 the leg section and the numeral 5 the foot section. These sections are pivotally related to one another so that the frame as a whole may be adjusted so as to provide for the comfort and convenience of the patient occupying the same or to suitthe requirements of the operator.

The body section 2 comprises a pair of tubular side members 6 with which are connected. transversely extending longitudinally spaced bars 7, and to these bars there is connected a plurality of longitudinally extending transversely spaced metallic strips 8, which are arranged sufficiently close together to provide for the positioning thereon of a pad, mattress or the like (not shown) upon which the patient rests.

Contiguous to its end the body section 2 has fastened to its side members 6 a plurality of fittings 9,with which are connected transversely extending rods 10,which serve to brace the body section 2 so as to produce a very substantial rigid frame construction. The fittings 9 also receive the upper end of depending tubular leg sections 11, which are removably and adjust-ably positioned in vertically arranged sockets 12 provided in upstanding fittings 13 provided on a portable base frame 14.

The base frame is formed to include longitudinally extending side bars 15 having their ends connected with the fittings 13 and with transversely extending bars 16 which, in turn, have their ends secured in any suitable manner in connection with the fittings 13. Also swiv'eled in the lowerv portion of the fittings 13 are the upright standards of wheel yokes 17, which carry at their lower ends rubber tired wheels 18 of any suitable design. The wheels 18 and the yolres 17 freely turn with respect to the fittings 13 so as to facilitate the transportation on the cot, to render the same solid and convenient to move and to facilitate turning or steering thereof. If desired, the socket 12 may have the walls thereof equipped with set screws or the like 19 by which the height of the frame 1 with respect to the base may be varied and maintained.

Also, by loosening the set screws 19 the frame I 01-110, A conronarron or nected with the body section 2 by providing 1 may be lifted bodily from the base section and carried manually after the manner of an ordinary structure. This is adesirable feature in moving patients when it is not possible or convenient to employ the poi'tabl base section.

The head section 3 of the frame 1 is conthe side members 6 of thelatter with fittings 20 having their upper ends provided with ears'21 apertured to receive pins 22 which are employed to pivotally connect with ears the ends of a U shaped bar 23 constituting the main frame of the section 3.- To

thespaced legs of "the bar 23 there :is connected a plurality of transversely extending bars 24,'with which are connected at transversely spaced intervals a plurality of longitudinally extending bars 25, which coopcrate with the bars 7 'andS to provide a base for the padding or mattress used in connection with the cot. The head sections may also be provided with a folding hood or canopy 26 by which the patient may be protected from inclement weather when the cot is used in exposed places. When folded the bar 23 rests on the side members 6, as shown in Figure 3/ However, it is possible to elevate the head section 3 to assume various positions of inclination with respect to the body i said frame is swung. about the axis provided the associated pad or mattress.

by the pins 22. i

In the particular form ofthe invention illustrated the legsection 4: of the frame 1 is also vertically adjustable or hingedly connected with therbody section 2. This may be accomplished by providing the side members 6 witlrfittings formed to be received within slotted fittings 31 provided upon the U shaped frame 32 of the leg section 4. The leg section, as is the body and head sections 2 and 3. is formed to include fixed transversely extending bars with which are connected spaced longitudinally extending bars 3 1, which constitute a base for the reception of Also, to sustain the leg section in its, positions of vertical adjustment,'there is provided a bail 35,

' corresponding in construction and principle to the bail 28. The bail 35 is formed with notches 36, which are receivable upon projections 37 formed with the bars 16 of the base. This arrangement permits of the locking of the leg section in its various positions of vertical adjustment.

The foot section 5 of the frame includes a U shaped bar 38, having the lowerend thereof provided with fittings'39 which frictionally' engagethe frame 32 of the leg section. This enables the foot section to be brought to a'position in the horizontal plane of'the leg section or to occupy a position, as shown in Figure 3, substantially at right angles to the plane of the leg section. The bar 38 has suitably connected'therewith a foot padding 40,

which provides a cushioned rest for the feet able within sockets a l, )rovided in the fittings 7 20. T he plungers 413 are connected with exte- .rior operating portions 4.5, which may be manually grasped so as to draw the plungers 43 out of the pockets 44, and to thereby allow the side rails to'be swung in vertical planes until they assume horizontal positions substantially in registration with the plane of the body section. When elevated andlocked, however the side rails serve to securely conline a patient upon the frame 1 and prevent accidental falls. 1 1

The side members 6 of the upper end of the frame are of tubular, construction so as to receive slidable handle sections 46, which are extended when the frame is being used as stretcher, but are forced to assume collapsed positions when the frame is'mounted for movement on the portable base.

In view of the foregoing it will be seen that the present invention provides a conveniently operated and efficient apparatus for facilitating the carrying, transportation or removal of sick, incapacitated or helpless persons or bodies and is especially constructed to meet the needs for ambulance or hospital service or for mortuary establishments. The frame 1 is formed from light weight metal so as to be capable-of being readily carried and by the articulated construction of the various frame sections thereof the device may bereadily adapted to supportand carry a patient in the most desirable positions. Also, by constructing the frame 1 so that it may be removed from itsbase or carriage 1 1, considerable facility is to be hadin moving patients up and down s air flights or from other localities wherein it is not convenient or desirable to carry the base frame. 4 V W hat is claimed is: I c e 1. An ambulance cot comprising a'frame, head and footsections pivotally connected with said frame, outwardly and laterally swinging side rails pivotally connected with surrounding said side members, spring pressed plungers carried by said fittings and 10 adapted to engage With the fittings of said head sections for balancing said side rails in an upright position.

In testimony whereof I afiix my signature.
