2 Claims.

This invention relates to cots especially adapt ed for the handling of sick or injured persons or the conveying of corpses.

The primary object of the invention is the provision of a device of the above stated character which will reduce to a minimum the amount of effort attendants will have to expend in the movement of persons either Vinto or out of ambulances and similar vehicles and from place to place in hospitals and similar establishments or within dwellings and up and down stairways, with maximum comfort assured to the person being moved.

With these and other-objects in View as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination and arrangement of parts which will be hereinafter more fully described and claimed.

For a complete understanding of our invention, reference is to be had to the following description and accompanying drawings, in which Figure 1 is a side elevation illustrating a portable cot constructed in accordance with our invention.

Figure 2 is a top plan View illustrating the device.

Figure 3 is a top plan View illustrating the carriage in operative position.

Figure 4 isa top plan view illustrating the carriage in a collapsed or folded position.

Figure 5 is a fragmentary sectional View illus- Atrating one of the track members and its connection to a leg of the portable carriage, taken on the line 5-5 of Figure 1.

Figure 6 is a sectional View taken on the line 6-6 of Figure 5.

Figure '7 is a fragmentary side elevation illustrating a head portion of the main frame in elevated or raised position.

Figure 8 is a perspective view illustrating one of the detachable clips used for supporting an X-ray plate on the device.

Referring in detail to the drawings, the numeral 5 indicates a main frame of elongated formation and composed of sections 6 and 1. The sections 6 and 'I have rounded ends and are preferably'constructed of cylindrical stock. Rigidly connected to the section 6 of the main frameV are spaced parallel skids 8. The ends of the skids '8 are rig-idly connected by arcuately curved braces 9 and the section Ii is rigidly connected to one of the braces 9, as shown at IIJ. The other connections between the section 6 of the frame 5 and the skids are indicated b-y the character I I. Also,

it will be seen that the ends of the section 6 are integrally connected with the skids 8, as shown at I2, and applied to the connected ends of the section 6 are detachable clips I3 including pivotally connected sections I4 and I5.

The sections I5 are in the form of straps to encircle the section 6 of the frame 5 and have the ends connected by removable pivots I6 which pivotally connect to the sections I5 the sections I4, the latter being socketed to receive `the ends of the section 'I ofthe frame 5. The ends of the section 'I of the frame 5 are fixed in the sections I4 in any well known manner. This construction permits the section 'I to be raised and lowered and forms the head portion of theframe 5.

Braces, I1 are pivoted to the side portions` of the section I of the frame 5 and have notches I8 to engage with a series of pins I9 secured on the skids 8 whereby the head section of the frame may be adjusted into different elevated positions and when the braces I1 are disengaged from the pins, the said section I may' rest on the skids and one of the braces 9 of said skids. Y Y Y In order to form the main frame 5 into a be structure, a sheet of material 20 is yieldably attached to the section 'I of the frame 5 and to upper rails 29 of the skids 8 bya series of coil springs 2|. The material20 may be of any desired fabric having sufiicient strength and durability to withstand the lWeight of a person thereon and for use over long periods of time. The springs ZI are to provide a cushioning effect to the person resting upon the sheet of material and may be detachably secured to thev frame 5 so that the sheet of material can be removed and replaced by another when necessary.

A rigid hand grip 22 is formed on the end portion of the section 6 of the frame 5 and a hand strap 23 is secured to the end portion of the section 'I of the frame 5. The hand grip 22 and strap 23 provide convenient means for lifting the frame 5 and the person thereon. When the strap 23 is not in use it may be arranged under a pillow used for the support of a persons head and not shown. The hand grip 22 also provides a foot restfor the person on the device.

Side hand rails 24 are detachably secured by Aclamps 25 tothe sides of the section 6 of the frame 5. The clamps 25 are sectional with the sections hingedtogether, as shown at 26, and further connected by removable bolts 21 which hold the sections of the clamps together in operative position on the frame 5 as well as detachably securing the hand rails to the clamps. The clamps 25 permit the hand rails 24 to be adjusted on the frame 5 and also to permit the hand rails to be swung downwardly orv entirely removed, if desired, when placing a person on or removing him from the bed structure.

The skids 8 include upper rails 29 having integrally connected therewith runners 3l] provided with upwardly inclined end portions 3I. The runners constructed as specified will permit the frame 5 while carrying a person to be slid along a surface or over the nights of a stairway. Also,

the arrangement of the runners will permit a person to be taken down a stairway in a horizontal position by allowing the inclined portions 3| at one end of the skids to slide over the ilights while the frame 5 is supported horizontally by an attendant.

A carriage 32 is provided for the support of the frame 5 when it is desired toemploy the device for transporting a person so that the expenditure of eiTort on the part of the attendant or attendants will be reduced to a minimum. The carriage is constructed to receive the runners 30 of the skids by supporting the frame 5 in a horizontal position and approximately at the height of an ordinary bed so that a person can be safely and easily transferred from the bed to the device or vice versa.

The carriage is detachable from the runners 30 of the skids so that when it is desired to place the frame 5 in an ambulance or similar vehicle, the carriage can be easily detached from the skids and the latter employed for sliding the patient into the ambulance and the construction of the skids is such that they will be readily adaptable to the fixtures employed in ambulances and similar vehicles for the support of stretchers or the like.

The carriage 32 can be readily collapsed, as shown in Figure 4, when not in use so as to only occupy a minimum amount of space and consists of substantially U-shaped members 33 arranged in pairs and formed integrally with vertically arranged legs or posts 34 carrying at their lower ends castors 35. A clamp 36 is employed for connecting the U-shaped members 33 in diverging pairs, as clearly shown in Figure 3, and which will permit the U-shaped members to be swung into parallelism, as shown in Figure 4, for collapsing the carriage.

The clamp 36 includes hingedly connected sections 31 provided with openings through which extend the substantially U-shaped members 33. The sections of the clamp 36 are secured to the U-shaped members 33 in any well known manner. A fastener 38 is provided for releasably securing the sections 31 of the clamp against hinging movement. Therefore, it will be seen that it is only necessary to release the fastener 38 when it is desired to move the U-shaped members in parallelism, as shown in Figure 4, for collapsing the carriage. To hold the U-shaped members 33 in operative position, as shown in Figure 3, braces 39 are pivotally connected to U-shaped members of each pair and detachably connected to the other U-shaped members. When the braces 39 are not in use for holding the U-shaped members in operative position they may be swung into parallelism with the U-shaped members to which they are pivoted and retained in the latter position by engaging pins 40.

Mounted for a limited rotary movement on the upper ends of the legs 34 are channeled track members 4|. The limit of rotation of the track members 4| is provided for by lugs 42 .thereon operating in notches 43 provided in the legs. The track members 4I slidably receive the runners 30 of the skids 8 and are equipped with removable pins 34 to overlie the runners 30 to prevent them from rising upwardly out of the channeled members during the use of the device. Also the pins 34 may act to prevent endwise movement of the runners 3U of the skids in the track members by said pins contacting brace members of the skids, the brace members being indicated by the character 45.

When the carriage is in an operative position, the track members assume the position as shown in Figure 3 so as to receive the runners of the skids. However, when the carriage is collapsed the track members may be swung to overlie the substantially U-shaped members.

Referring to Figure 8, a spring clamp 46 is shown and has connected thereto a hook 41. A number of clamps 46 may be applied to the frame 5 for the purpose of supporting thereunder an X-ray plate so that X-ray pictures may be taken of a person resting on the device. The hooks 41 of the clamp may be easily and quickly applied to any portion of the frame 5 and removed therefrom when desired.

From the foregoing description taken in connection with the accompanying drawings it will be seen that a very practical device has been provided for the conveying of persons with comfort to the persons and with a minimum effort on the part of the attendant, and that the device may be used with the carriage at any time desired and that the carriage can be conveniently removed and collapsed when it is preferable to use the device on the skids 8.

While we have shown and described the preferred embodiment of our invention, it will be understood that minor changes in construction, combination and arrangement of parts may be made without departing from the spirit and scope of the invention as claimed.

Having thus described the invention, what we claim is:

1. In a portable cot, a main frame including a foot section and a head section each of U-shaped formation, means pivotally connecting the ends of the head section to the end portions of the foot section for raising and lowering said head section, a pair of skid frames each including a. longitudinally extending upper frame member and a longitudinally extending lower frame member having a central portion rigidly secured in spaced parallel relation to the upper frame member and end members inclined upwardly from the central portion and rigidly connected to the upper frame member, means rigidly connecting the upper frame member of the skids to sides 0f the foot section, and adjustable braces connecting the head Vsection to the skids.

2. In a portable cot, a main frame including a foot section and a head section each of U-shaped formation, means pivotally connecting the ends of the head section to the end portions of the foot section for raising and lowering said head section, a pair of skid frames each including a longitudinally extending upper frame member and a longitudinally extending lower frame member having a central portion rigidly secured in spaced parallel relation to the upper frame member and end members inclined upwardly from the central portion and rigidly connected to the upper frame member, means rigidly connecting the upper frame member of the skids to sides of the foot section, adjustable braces connecting the head section to the skids, a pair of side rails, and clamping members connecting the side rails to the sides of the foot section.
