1 Claim.

This invention relates to an air conditioned canopy and has for its principal object the provision of a small housing to be placed over a bed to agreeably comfort an occupant lying therein regardless of the temperature in the room in which the bed is placed.

A further object of this invention is to provide a canopy adaptable to private homes, hotels, and hospitals, the interior of said canopy to be air conditioned to a desired degree of temperature to meet the condition of an occupant lying in the bed whether normally in good health or a patient to be treated to combat an abnormal condition either by a high or low degree of temperature as the case may require.

A further object of this invention is to construct a light durable frame having means to detachably secure the same to a bed frame and the said first frame being enclosed with a material that will maintain the temperature created within, and furthermore the said enclosure being of such material that will avoid condensation when the interior of the canopy is air conditioned to a low degree of temperature.

A still further object of this invention is to provide accessible means to a patient from either side of the bed and the said means being a convenience to enter the canopy and emerge therefrom.

These and other objects will hereinafter be more fully explained, reference being had to the accompanying drawings forming a part thereof, and in which like characters will apply to like parts in the different views.

Referring to the drawings:

Fig. 1 is a side elevation of the canopymounted on a bed structure, the curtain at the head of the canopy being vertically positioned, but adapted to enclose the head of a patient as shown by dotted lines.

Fig. 2 is a foot end view of Fig.

Fig. 3 is a head end view of Fig. 1.

Fig. 4 is a, longitudinal section through the canopy to illustrate the side frame and its jointed sections and direction of their rocking movements, also the clamping means for the frame to a side rail of a bed.

Fig. 5 is a fragmentary plan view of the top of Fig. 4.

Fig. 6 is a fragmentary sectional view taken on line 6-6 in Fig. 1.

Fig. 7 is an enlarged longitudinal section through a standard to illustrate a snap fastener for the textile covering to the frame.

Referring to the drawings in detail, it will be seen that the invention relates to a canopy comprising a. pair of standards I and 2 respectively for each side of the structure in spaced relation and removably connected to a bed frame as later described, the standards at their upper ends being hingedly connected to side rods 3 as at A and B and the said side rods being rule-jointed as at C and D to fold as indicated by arrows in Fig. 4. Said standards are adapted to rock inward toward each other at the time of folding the canopy, the side rods 30 being connected by cross rods 4 at each end and intermediate thereof. Threadedly engaging on the lower ends of each pair of standards are clamps 5, the jaws of which are adapted to straddle the side rails 6 of a bed structure and being secured by bolts 1. It will now be seen that standards I will function as an anchor while standards 2 are the fulcrum points to support the forward extension of the side rods to maintain a level alignment of the top of the canopy. The frame thus described has an enclosure 8 preferably made of canvas and being secured to the frame by removable fasteners 9, the sides and foot end portions being adapted to lap over the bedding to exelude external temperature from the interior of the canopy, and the head thereof has a curtain ill to close the same, said curtain being detachably carried by its. respective cross rod and normally vertically positioned, however, the said curtain being of suitable length to enclose the head of an occupant as shown by dotted lines E; otherwise the head may be exposed by moving the lower extremity of the curtain rearward, but at all times maintain a sealed enclosure.-

As a means to air condition the interior of the canopy, there is provided a duct I I as a conductor for air injection to the interior thereof, said duct arranged to communicate through the foot or rear wall of the enclosure concentric thereto or may be otherwise located. The duct is made likewise of canvas and has suitable annular ribs to maintain the same tubular in form; furthermore there is provided a flange F for the mouth of the duct and being removably secured by ball and socket fasteners I2, the other end being in connection with a standard make of generator as at l3 that may be placed under the bed or elsewhere, or may be connected to an air conditioning plant installed in the building;

however, it will be understood that the said canopy may be separately air conditioned to vary its inward temperature from that in the room in which it is placed.

While I have shown the frame constructed of tubular elements, the same may be varied by the adoption of solid bars, but in any variation the metal is preferably of aluminum alloy, and likewise, the enclosure being specified as canvas, the same may be substituted by rubberized fabric or other material so long as the interior or the canopy is substantially air tight or at least void 01 free external communication, whereby an even temperature is maintained for the purpose specified, and such other modifications may be employed asjlie;witl' in the scope qf the ap- -E;

pended claim.

Having fully described my invention what I claim as new and desire to secure Letters" ru e-m n ed a 1 t rod for each side of the canopy top,""a pairo'f Patent is:

In a canopy for a bed, a plurally scrlbed. 3 it other end of the frame and extending downward therefrom, all substantially as shown and del LEIGH E. JOHNSON.
