This invention relates to air conditioned bed compartments, and particularly to a portable air conditioned bed compartment carried by the bed and adapted to be easily assembled or disassembled.

The principal object of this invention is the provision of a canopy, carried by a bed, which in combination with the bed mattress, produces an insulated compartment, suitable for air conditioning.

Another object of the present invention is the provision of portable, and easily dismantled, compartments, wherein the conditioned air is effectually controlled to maintain the desired temII Perature at a reasonable cost.

A further object of the invention is the provision of a novelly constructed canopy carried by the bed and so related thereto as to allow for independent movement of the springs and mattress thereof.

Another object of this invention is the pro-, vision of an air conditioned bed compartment that is of neat and sturdy construction, that has novel means for controlling the conditioned air, and one that has suitable connections of the parts to form a compartment that will not leak too much of the conditioned air.

With these as well as other objects, which will appear during the course of the specification, in 0 view, reference will now be had to the drawings wherein: Figure 1 is a side elevation of an air conditioned bed compartment, partly in section, embodying this invention.

Throughout the several views, like reference characters designate similar parts, and the numeral 20 is a bedstead of the usual type, having is head piece 22, foot piece 24 and side rails 26.

Positioned between side rails 26 on ledges 28, are slats 30. Resting on slats 30 within the confines of the head and foot pieces and side rails, is a set of springs 32, having a frame 34 and coil springs 36 carried thereby. These coil springs carry the usual mattress 38. The legs 40 of the bedstead serve to maintain the side rails and parts carried thereby a predetermined distance above the floor. It is essential that the end slats be held in a fixed position relative to the side rails, and it is for this purpose that the angle plate 42, secured to the side rail by means of screws 44 and to the slat by means of screw 46, is provided. Adjacent each end of the end slats is pivotally mounted by means of bolt 48, a bracket 50, which is adapted to be oscillated in a horizontal plane.

This bracket 50 is provided with a vertical opening 52 at its free end, through which the vertical standard 54 is adapted to be fitted. This standard is secured against downward movement by means of an adjustable set collar 56, provided with a set screw 58. By means of this structure, it is apparent that by properly positioning end slat 30, the vertical standard 54 may be located at the adjacent corner of the mattress and near the intersection of the end piece and side rail.

Since each of the end slats is provided adjacent its opposite ends with like standards and standard mountings, a vertical standard is provided at each corner of the mattress. These standards, together with associated parts, as hereinafter described, constitute a canopy which, in conjunction with the mattress, produce a compartment 60 which serves as an enclosure for the occupants of the bed.

Referring particularly to Figs. 4, 5 and 6, it will be observed that tubular side bars 62 and 64 5g 2 2,188 are mounted in spaced-apart, parallel, relation, one above the other; also, a tubular end bar 66 is provided as a transverse connection between the standards at the head and foot of the 'bed respectively. Supported by each of the standards 54 is an angled bracket 68, which extends inwardly to rest on the end bar 66 with one leg thereof projecting upwardly to receive an offset, tubular side bar 70 and an end bar 72, which is spaced apart from end bar 66 and positioned thereabove. The side bars 10 are joined together intermediate their ends by means of a cross rod 74. In certain instances, a plurality of these cross rods 74 might be used.

With reference now to Fig. 9, which represents an end portion of either of the tubular bars 62, 64, 66, 10 and 12, together with the connector 75, such connector is provided with a cylindrical body 76, that is fitted into the end of the tubular member and secured by punching a portion of the tube 78 into the recess 80 formed in 76. That portion of the connector 15 which extends beyond the tubular bar is flattened as at 82 and provided with an opening 84, through which the re28 duced end 86 of plug 88, carried in the upper end of standard 54, projects.

Plug 88 is threaded at 89 and provided with a blind nut 91 which holds the assembled parts together and also gives a finished, smooth surface to support the top member, as hereinafter set forth. The relation of the framework parts just described is clearly detailed in Figs. 5 and 6.

The frame, when so constructed and mounted on the bedstead, serves as a support for insulating flexible side and top members to produce a compartment above the mattress, which may be air conditioned.

Vertical wall member 90, shown in stretchedout form in Fig. 10, is provided at its top edge with a series of spaced-apart loops 92, which are adapted to be threaded on tubular side and end bars 62 and 66, as clearly shown in Figs. 1 and 2.

The bottom edge of wall 90 is provided with slits 94, one of which is at each of three corners of 4& the compartment. Those portions of the vertical wall 90 intermediate slits 94 and between slits 94 and the ends of wall 90 are adapted to be folded underneath the mattress so as to rest between mattress 38 and springs 36 to 5 provide a seal between said members. Small coil springs 100, attached at one end to the lower edge of vertical wall member 90 and at their other ends to one of the inner springs 36, serve to maintain the parts in proper operative rela* tion.

Referring to Figs. 1 and 2, it will be noted that vertical wall 90 is sufficiently long to provide a downwardly extending loop 102, thus making it possible for the mattress and springs tc So lower with respect to bars 62 and 66 withoul putting undue tension on the wall 90. This fea. ture is very important in view of the fact that thi vertical wall member 90 is preferably made o quilted, spaced-apart sheets of fabric, with ai insulating material therebetween, which woul be greatly damaged by any undue tension or pul thereon.

The ends 104 and 106 of vertical wall membe 90 are joined together as shown in Figs. 3 and 1I 0T Glove fastener units 108, which are adapted t be snapped together, serve to join the two end with the vertical wall member in the positio shown in Fig. 12. The end portion 104 is al provided with a vertically disposed rod 110, t M which is attached hook members 112 that engaE ,078 the standard 54. These hook members serve to hold the end of the wall member 90 in position durnig the placing of the same on the standards.

One of the side walls 98 is provided with a door 114, formed by cutting the side wall ver- B tically-at 116 and horizontally at 118, and providing the edges created by said cuts with fasteners 120 which are commonly known as slide fasteners,- thus making it possible to disengage adjacent edges and slide the door member on its 10 supporting loops 92 along bar 62 to permit entrance to and exit from the compartment.

Side walls 98 are provided with attached flounces 122, which may be positioned to cover side rails 26. 15 Referring now to the top member 124, which is substantially rectangular in form with notched corners 126, and made of a pliable material with insulating qualities. The edges of each of the notched corners are provided with slide fasteners 20 means 128, which serve to secure said edges together. Also, each side portion of the top member is provided with a longitudinally extending rod 130, which is securely attached at the inside thereof, as clearly shown in Fig. 6. This rod is 2U secured in the position shown by means of latches 132, carried by angle brackets 68 to produce an offset 134 in the longitudinal upper edges of the top member. This forming of the top member produces a pleasing effect to the canopy. It will 30 be noted that the edge portions of the top member 124 overlap the vertical side and end walls to form a suitable seal between the parts. This top member is cut away at 136 at the head of the bed to permit free flow of the air through the 35 screened ventilating opening 138, formed in the vertical end wall. This opening is provided with a closure 140, having a fastener 142, by means of which it may be secured in the closed position to preclude the movement of air through 138. 40 For purpose of lighting the compartment, an Incandescent lamp 144, supported by cables 146 to end bar 66, is positioned below said screened ventilator.

Each end of the bed is provided with an air 45 duct 148, which extends vertically through an opening 150, formed through the vertical wall member 90 and terminates in a distributing head 152. This head extends horizontally between standards 54, to which it is secured, by means of 50 hook members 154. These hook members rest on adjustable collars 156, mounted on the standards. Air passing from duct 148 to the distributing head is deflected to a horizontal flow by means of the curved wall member 158 mounted a in said distributor head. Graduated openings S160, formed through the inside face of head 152, Sserve to equally distribute the air passing from Ssaid distributor head across the full width of said t bed. Due to the fact that the pressure of the air s0' . adjacent duct 148 is greater than at the end of e the distributor head remote therefrom, openf ings 160 are made smaller adjacent the duct and n gradually increase in size as their distance is d increased from said duct. 05 11 Preferably, the circulation of air through the cooling unit 162 to and from said compartment r is in the direction indicated by the arrows. The . cooling unit 162 may be of any of the well known o types that will cause a circulation of the com- 70 Is partment air to condition the same, both as to n temperature and humidity. The diagrammatic o showing of the cooler system 162 is of the com;o pressor type, wherein 164 indicates a compres'e sor; 166 cooling means, over which the air to be Ig conditioned is passed, and 168 is a suitable con denser. In order to make this cooling unit port able, means for taking care of the condensat from the cooling coils is provided. The coolinj coils are mounted in a cabinet 170, wherein th condensate collects as at 172, thence passe through tube 174 to an evaporating pan 176 The liquid thus introduced into pan 176 is rapid.

ly evaporated thereby eliminating the necessitj of Providing drain tubes to carry the condensatt from the room. A suitable ventilating fan 171 causes the air to be circulated through said system. It will be noted that the entire cooling element is Positioned beneath the bed and may be easily moved therewith. Thermostat or temperature control means 161 may be located within the compartment or the air ducts to regulate the temperature of said compartment.

Referring now to Figs. 13 and 14, which show a modified form of the air distributor, it will be noted that the duct 148 terminates in a narrow head 180, which is secured to one of the vertical standards 64 by means of collars 182.

In order to Properly distribute the air over the entire width of the bed, diagonally disposed blades 184, mounted in head 180 adjacent the opening 186 formed therein, directs the air diagonally across the bed at varying angles.

A further modification of the diir conditioning 0 means is Thown in Figs. 15 and 16, and comprises a casing 188, carried on standards 54 by means of hooked brackets 190. Collars 192, positioned on standards 54, serve as supports for said brackets. Air passes into compartment 194 31 through strainers 196 and is forced by the motor driven fan 198 over the expansion coils 200, thence out through the screened openings 202 formed through the inner wall of casing 188. A temperature control means 204 may be provided to regulate the expansion valve 206 that controls the amount of refrigerant Passing to the expan- sion coils 200. While this air conditioning unit is not shown complete, yet it is sufficient to teach e that a unit of this type Properly constructed g could be used within said compartment for the e Purpose intended. I s Many minor changes might be made in the construction and relation of the several parts, Sand It is desired to be limited only by the scope r of the appended claim. S What I claim is: S In an air conditioned bed assembly having a Smattress, springs beneath the mattress and slats supporting the springs, a compartment, positioned above the bed and bottomed by the mattress thereof, comprising brackets Pivotally secured at their one end to the slats at the end of the bed beneath the corners of the mattress for oscillation in a horizontal plane; a vertical standard carried by the other end of each bracket; an open frame setting off an area substantially equal to that of the mattress carried by the standards above the mattress; a wall of heat insulating material, having its upper edge secured to said open frame, circumscribing the mattress and having its lower marginal edge extending inwardly between the mattress and springs; yieldable means connecting the lower inturned edge of the wall to the springs of the bed; and a top member of heat insulating material covering the frame to form, with the wall 80 and mattress, a box-like enclosure, said wall having a Plurality of spaced apart loops along the upper edge thereof, slldably engaging the frame, one stretch of said wall along one side of the mattress being provided with a slit ex- I3 tending inwardly from said upper edge to a point substantially on the extended plane of the upper side of the mattress and thence longitudinally to set off a displaceable portion of the wall for the Purpose specified. 41 ~EiRY V.
