No. 412,553 12 Claims. (Cl. 297-180) This invention relates to folding chairs and more particularly to chairs for cooling the occupants.

A principal object of the present invention is to provide a chair with cooling means in the seat portion and in the back rest portion of the chair.

Another object of the invention is to provide a chair with a cooling band at the forward end of the seat portion and with a cooling band at the top end of the back lrest portion.

A further object of the invention is to provide a chair with a vapor cooled band at the forward end of the seat portion, a vapor cooled band at the top end of the back rest portion and an electric fan disposed underneath the seat portion at the rea-r increasing the evaporation of the sponge ropes and as a result increasing the cooling or the vapor-cooled band, at the top of the back rest and over the band at the front of the seat.

Yet another object of the invention is to provide a chair of this kind with a pivotal back rest and means for holding the back rest in moved adjusted position.

Still another object of the invention is to provide a chair of this kind with an adjustably-mounted electric fan and means for adjusting the position of the fan.

For further comprehension of the invention and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings and to the appended claims in which the various novel features of the invention are more particularly set forth.

FIG. 8 is a perspective view of the shaft mounting the back rest and electric fan with modified means for rotating said shaft.

FIG. 9 is a view similar to FIG. 6 showing the seat, back rest and electric fan in adjusted position.

Referring now in detail to the various views of the drawings, in FIG. 1 a wicker chair 10 is illustrated embodying the invention. The chair 10 comprises a rectangular seat 12 supported for movement on a front ground-engaging U-shaped tubular metal frame 14 and a rear ground-engaging U-shaped tubular metal frame 16. A back rest 18 is pivotally connected to the rear end of the seat 12 and iianged at arm rests 20, 20 are suitably supported on the top ends of the

legs

24, 24 and 26, 26 of the

U-shaped frames

14 and 16, respectively, the

bight portions

28, 28 of the

frames

14 and 16 resting upon the supporting surface 30. The frame 12 is supported conventionally on front and

rear frames

14 and 16, respectively, and back rest 18.

The seat 12 comprises a U-shaped tubular metal frame 32 over which longitudinal rectangular strips 34 and transverse rectangular strips 36 of wicker are stretched in criss-cross fashion. Adjacent the bight portion 38 `of the frame 32 at the front of the seat, the longitudinal strips 34 are reduced in width to form narrow portions 40.

The back rest 18 comprises an inverted U-shaped tubular metal frame 42 over which longitudinal rectangular strips 44 and transverse rectangular strips 46 of wicker are stretched in criss-cross fashion. Adjacent the bight portion 48 of the frame 42 adjacent the top of the back rest, the Ilongitudinal strips 44V which are continuations of strips 34, are reduced in Width to form narrow portions 50.

The free ends of the

legs

52, 52 and 54, 54 of the seat frame 32 and back rest frame 42 respectively are pivotally joined by a round shaft 56 Which extends across the space between said ends and extends through juxtaposed

perforated ears

58 and 60 on the

legs

52 and 54, respectively, and therebeyond. Perforated ilanged discs 62 are mounted on the protruding ends of the shaft 56 disposed in line with the legs 26 of the reai U-shaped frame 16.

The top free ends of the U-shaped

frames

14 and 16 are pivotally connected to the flange 64 of the arm rests 20 by pivot pins 66 and the legs 54 of the inverted U- shaped frame 42 of the back rest 18 are connected to the ange 64 of the arm rests by pivot pins 68.

A thin elongated rectangular strip 70 is suitably secured t-o the transverse strips 46 of the back rest 18 and to the transverse strips 36 of the seat 12 at the corners of said strip 7 0 as indicated at 72 and 74, respectively. The strip 70 ends just short of the narrow portions of the Wicker strips and serves as a backing and reinforcing strip for the wicker strips as best seen in FIG. 3, and serves to maintain -a maximum quantity of air coming from the fan to the vapor-cooled bands. This increases the evaporation and accordingly the cooling of the bands.

In .accordance with the present invention, mechanism is provided at the front end -of :the seat 12 and .at the top end of the back rest 18 for cooling the occupant of the chair. For this purpose, t-hin rectangular-shaped metal plates 80, are placed across the narrow portions 40' -of the seat 12 and across the narrow portions 50 of the back rest 18 and secured to the legs of the

frames

32 and 42, respectively, by rivets 82 extending through holes in lthe ends of the plates that are curved over the legs of the frames. Thin :absorbent or

cotton sheets

84, 84 of a shape similar'to the

plates

80, 80 are clamped along the long edges thereof to the long edges of the plates 80 :by rubber bars 86, the edges lof the sheets Iand bars being secured in -place by adhesive, t-he remainder of the sheets being loosely spaced from the platesv80, The plates 80 and sheets 84 deiine elongated compartments 88 in which are placed 'a plurality of ropes 90 of wick or sponge or other wick-like material, the ropes being stitched to the sheets 84 as indi-cated at 92, extending outwardly of the compartments 88 :and being connected to water supplies consisting of box-like containers 94, each having a supply of water 96. The container 94 at the front of the seat 12 is secured to the frame 32 by means of brackets 98 carried by the box and 4riveted to the frame. The container 94 for supplying the water to the ropes on the back rest 18 is similarly fastened by brackets to the plastic sheet 70 at the rear end of the seat 12. The free ends of the ropes 90 pass through openings 100 in the top of the containers 94 'and are immersed `in the water 96 in the containers. lThe ropes are

moislthe plates

80, 80 on which the occupant sits and against through evaporation Iof the sponge ropes resulting in a 3 cooling of

theplates

80, 80. The containers 94 are provided with openings 102 for supplying water thereto which openings are sealed by removable plugs 104.

Another cooling medium in the form of an electric fan 108 is swivelly mounted on the shaft 56 midway the ends thereof, by means of a metal str-ap 110 connected at its ends to the frarne of the fan and looped at its center around the shaft. An electric motor 11 2 is suitably fastened to the frame of the fan and is supplied with a conductor 114 leading to an electric switch 116 wi-th an actuating button 118, mounted on one of the arm rests 20. A cord 120 with plug 122 leads from the switch for connection to a source of E.M.F. t

The mounting of the fan 108 permits it to -be turned 90 in a vertical plane and for this purpose an elon- -gated lactuating rod 124 is provided which rod has one end hooked around the frame of the fan. The rod is formed with an offset portion extending at right angles to the plane of the rod and adapted to seat in and interlock with spaced teeth 128 on .a flanged bracket 130 riveted to the sheet 70 to hold the fan in adjusted moved position. The other end of the rod terminates in a looped handle portion 132 for manipulating the rod. By pulling upwardly on the rod, the fan 108 may be swung from a horizontal plane as se'en in FIG. 1 to a vertical plane as seen in FIG. 9 or any desired angle therebetween.

In operation, the angular relationship between the seat 12 and hack rest 18 is readily adjusted by removing the flanged disc 62 which is held in position on the end of shaft 56 by means of a rubber washer 136 which is easily slipped olf of the shaft.

When the disc 62 has been removed, the back rest can be manually swung forwardly or rearwardly as shown in FIG. 6 to desired position after which the disc 62 `is replaced on the shaft 56 with its flange against the -adjacent leg 26 of the rear frame 16 thereby frictionally holding the parts in moved adjusted Iposition.

The ropes 90 being submerged in the water 96 in containers 94 .are kept moistened by capillary action so that the plates 80, S on which the occupant sits and against which his back rests are always in cooled condition. This cooling action is supplemented by the electric fan 108 which when turned on increases the evaporation of the sponge ropes under both

plates

80, 80 tand increases according to the cooling of both pla-tes simultaneously.

If it is desired to cool the seat 12 more than the back rest 18, the fan is moved to a vertical position as shown in FIG. 9 whereupon the `air is directed forwardly under the seat. In order to blow -most of the air upwardly to cool the back rest 1S, the fan is moved to a horizontal position as shown in FIG. 1. This adjustment of the fan is accomplished manually by means of the rod 124.

ln FIG. 8 a modified form of flanged disc 62 is shown for manually turning the shaft S6 so as to change the angular relationship of the fan 108 t-o the seat and back rest. The disc 62 is formed with an inwardly extending hub portion 140 around the perforation therein and depending from the inner surface of the -hub portion there is a lug 142 adapted to coact with .a slot 144 formed in the end lof the shaft 56 and intersecting the end edge thereof.

When the flug 142 is interlocked with the slot 144, the shaft is readily turned which in turn rotates the fan 108 fastened to the shaft by strap 110. v
