(C1.` 13s-_5.2) For a. clear understanding of an exemplary use for the invention described herein, reference is made to my co-pending applications Ser. No. may frequently be desirable particularly if the temperature of the conditioned air Within the canopy tends to become too low. My present invention, as addressed to the struc 714,687, filed March 8, 1934; Ser. No. 715,077, tures to which I have referred', pertains to the 5 filed March 12, 1934; and Ser. No. 716,488, filed , canopy construction and- to the supportingmeans March 20, 1934. In the saidv co-pending cases I therefor. The general objects of my invention have described a device for cooling and condition ing air in a restricted space for immediate oc cupancy whereby the comfort. and health of the user may be served without the provision of com plicated' and costly apparatus and the utilization of great amounts of power. In-the exemplary embodiments of my device therein described I have` shown the combination of a canopy over a l Ol bed to define an area of immediate personal oc cupancy together with electrical and mechanical means for conditioning and cooling the air with in the said canopy. In these embodiments the electrical and mechanical equipment or at least the greater part of it is contained in an orna 20 mental cabinet, stand'or housing member adapt ed to be placed alongside of a bed. The cabinet has an arm or arms extending upwardly and out wardly over the bed, to which arm or arms ther 2 canopy is attached and by which it is supported. The lower edges of the canopy are free and are tucked in around the edges oi the bed e. g. around the mattress. Thus a closed space is provided. It has been found most convenient and effective to provide a canopy of the general style of the 3O familiar A tent, in which, however, the ridge is preferably of less length than the length oi the lower part of the canopy, both for convenience in supporting the device and also to restrict the space to be cooled and conditioned to the mini concern themselves with` a solution of the problemsA to which I have referred, and these and other objects of my invention will be apparent to 10 one skilled in the art upon reading these speci ñcations wherein I have described an exemplary -embodiment of my preferredV construction and arrangement of parts whereby these objects are attained. Reference is now made to the draw ing wherein: Fig. l is a side elevation of my completed ap paratus. Fig'. 2 is a plan view of an- access and control opening. 20 ~ Fig. 3 is a perspective view of the completed canopy frame structure. - Fig. 4 is an elevational view of an- end frame member. In Fig. 1 I have shownl a bed Iv having a mat 25 tress 2 resting upon> the usual spring construction. At 3v I have shown the cabinet of one of my air conditioning and cooling devices. This will not be described in detail since reference to my co pending applications is deemed sufñcient to ap 30 prize the skilled worker of the construction there oi". Moreover, the nature ci the mechanism With in the cabinet 3» is not a necessary limitation upon my present invention. Briefly sta-ted; the cabinet 3 will contain a complete refrigerating mecha nism of which the high pressure side is located in a compartment sealed from a compartment in If the walls of such canopies, however, are which the low pressure or evaporator side is lo-j sloping it is advisable to provide means for keep cated'. Air for cooling the condenser is drawn ing these walls distended so that they will not lie in from: the room at large and exhausted to the upon or touch the face or body of the occupant room at large; The low pressure compartment is 4 O of the bed. Again there is the problem of pro sealed from the room at large- and air from the viding access to the canopy for the occupant pref canopy may be drawn thereinto through an open erably without the necessity of pulling the lower ing 4, passed through» the i‘nterstices of an edges of the canopy out from the mattress, enter evaporator and caused to re-enter the canopy 45 ing the bed from beneath them, and then tuck through an opening 5. Preferably the opening 5 45 ing them in around the mattress from the in will be provided with: a discharge device-adapted to side of the bed. Finally there is the problem of be movedi or adjusted toA control the direction of providing air exchange and controlling the tem air delivery. About these two- openings I= provide perature. As has been set forth in my co-pending a frame of'channel shape indicated at 6 to-which cases, if the canopy is made of proper materials the canopy- may be fastened in Ways taught in my 50 l 50 there will be suiñcient passage of external air into (so-pendingA cases. The canopy, of course, has an and out of the canopy through the fabric thereof openingv coextensive with the frame. The frame to maintatin adequate oxygen content and to 6‘ also serves to support a pair of angular arms avoid the feeling oi stuñiness inside the canopy. 'I` and 8` which extend upwardly for a- distance 55. However, a greater than normal infiltrationv of air mum. 2,133,846 suiiîcient to clear the canopy, and then extend the frame and the canopy are supported from the angularly outwardly, upwardly and divergently arms 1 and 8 by the engagement of the hooks I4 with the ends of the said arms. It will be clear, of course, that any manner of engagement of the ends of the arms with the corner fittings of my canopy frame fall within the scope of my inven as shown, so that the ends of these arms are comparatively widely interspaced and lie sub stantially over the center line of the bed. to these arms that the canopy 9 is hung. It is I have indicated hereinabovethat the canopy 9 is preferably in theshape of a tent having sloping side and end walls; but as aforesaid, it is desir 10 able to keep the side walls distended so that in stead of falling from the ridge to the edges of the bed in substantially a single plane, they fall out tion. Reference to Figs, 1 and 2 may be made for the construction of an access and control ar rangement which I employ in connection with my canopy. A side of my’canopy is provided with a triangular opening indicated at 25. The edges of this opening may be reinforced if desired by frame wardly at a greater angle for a substantial dis tance and then fall downwardly to meet the members in a way which will readily be under edges of the bed in as nearly a vertical plane as is stood by one skilled in the art although ordinarily I have not found this necessary or advisable. I 15 have found it preferable so to locate the tri angular opening that the base of the triangle is practicable. It will be clear, of course, that beds vary in size and shape and it is not ordinarily necessary with my construction to provide vary ing types of canopy for varying sizes of bed. Con 20 sequently, the “planes” to which I have referred upwardly disposed. Adjacent the downwardly ex tending sides of the triangle I sew triangular shaped flaps 26 and 21 which are adapted to be above are approximate in nature. As a framework for my canopy I prefer to pro vide the means illustrated in Figs. 3 and 4. Here ' I have shown end fittings which may be made of cast metal and which have a leg I0 adapted to be horizontally disposed and two other legs I I and I2 at the end of the leg I0, disposed at angles of substantially 90 degrees thereto but preferably disposed as respects each other at an These legs are perforated for the reception of arms providing frame members for the canopy and the perfora tions may be threaded or not as desired. The end members also have an upstanding leg 35 I3 at the other end of the leg I0. , This leg I3 is also perforated and is adapted to receive a hook member I4 by which the canopy frame may be 30 angle of less than 180 degrees. hung to the ends of the arms 1 and 8 which are perforated for the purpose shown. l A ridge for the tent may be formed by a single rod entering the perforations in the'leg I0 of two of the end fitting members; but I prefer to make the ridge of my canopy adjustable and tothis end I have shown the ridge in Fig. 3 formed of a pair of rods I5 and I6 each attached to a leg I6 of one of the end fittings, and fastened together in such a way as to be longitudinally adjustable. One such way is illustrated in Fig. 3 as compris ing a sleeve I'I through which both of the rods I5 50 and I6 pass and which grips these rods fric 40 tionally, so that while longitudinal adjustment may be made the rods will be adequately held in adjusted position.> The legs II and I2 of the end fittings receive 55 in their perforations side rods I8 and I9, 20 and 2|. The ends of these rods may be curled as at 22 or rounded or otherwise provided with means minimizing wear on the canopy. The various rods may likewise be of resilient metal. It is not 60 necessary and in some cases it is not particularly material but it is of advantage in many instances so to form the rods I8 and 2I. This gives to the canopy a measure of self adjustment to meet 65 varying conditions. The manner of use of the frame structure in cooperation with the arms ‘I and 8, and the con ditioning apparatus 3 by which they are support ed, will be clear from an examination of Fig. 1. 70 Two rods I5 and I6 form a ridge pole for sup porting the vridge of the canopy throughout its length. "I’he armsV I8, I9, 20 and 2| distend the sides of the canopy so that there is an angular displacement between more or less planar por 75 tions marked 23 and 24 of each side wall. Both disposed either to cover or to uncover the open ing in the canopy. To this end the unattached corner of each flap is provided with some fasten ing means, either a buttonhole 28 as shown, or a button, or one of the parts of a separable fastener. Corresponding fastening portions 29 and 30 are located on the Wall of the canopy adjacent an edge of the perforation 25 therein, so that the flaps may be held in closed position as illustrated in Fig. 1. Other cooperating fastener portions 3| and 32 may be located on the wall of the canopy so that the flaps may be fastened in opened posi tion. 'I'he flap 26 is shown fastened in opened po sition in Fig. 2. . I have found it necessary to provide but one such access opening in my canopy although more may be provided, if desired, in the same or in different wall portions. This opening not only provides ready access to the canopy without disturbing the relationship of the canopy to the 40 both of the flaps may be left open during the use of the structure. It will be noted that prefer ably the opening is disposed considerably above the level of the top of the mattress and also that the lowermost part of the opening has the least effective area. Thus, since cooled air is relatively heavier than warm air one or both of the flaps may be left open for greater air infiltration While 50 maintaining a body of cooled air adjacent the mattress and the coverings thereon. In this way the effect of conditioned air may be ob tained without the full lowering of temperature within the cabinet of which the apparatus is capable under any given conditions. „ Again one or both of the flaps 26 or 21 may be made of a material differing from the material of the canopy as by being more Apermeable to air. One or both ofthe flaps may thus be made of 60 netting. Again it is possible to provide a plu rality of flaps in place of each of the flaps 26 and 27. Thus each pair of. flaps may comprise one of netting and one of heavier material com parable to the material of the canopy, or more or 65 less air pervious. One such supplementary flap has been shown in Fig. 2 at 26a. l Modifications may be made in my invention without departing from the spirit thereof. Having thus described my invention,` what I 70 claim as new and desire to secure by Letters Patent, isz- ' „ f ' 1.
