Patented Mar. 14, 1939 FURNITURE Archibald Henry Finlaygv'Holywood, Northern Ireland `Application March 21, 1936, Serial No. 70,060 In Great Britain March 28, 1935 s claims. (o1. 155-179) This invention relates to armchairs, settees and like articles of furniture, presenting a recess to receive the users body between adjacent portions constituting arm or back rests.

According to my. invention, I provide an armchair, settee or the like article of furniture presenting a recess to receive the users body between adjacent portions constituting arm or back rests, the whole being constituted without rigid frame members by a single pneumatic chamber or a plurality of such chambers arranged so as to be self supporting r'with the aid of tie means controlling the distension of the chamber or charnbers under inflation. y

Furniture in accordance with the invention comprises envelope means such as an outer cover of leather, canvas, rubber or other flexible material adapted by shape and construction to re- `ceive and accommodate one or more suitably shaped removable inflatable and deilatable inner chambers provided with air valves, one or more pockets or compartments being formed in the outer cover or envelope to receive and retain the inated chamber in such manner as to provide the desired shape and to ensure its stability and comfort in use, the chambers and their respective casings or coverings constituting what is designated in theclaims as envelope means, and with- -in the envelope there is provided a core of packing, an additional packing or padding is provided to protect the walls of the inflatable chamber or chambers.

In order that the invention may be clearly un- Y derstood, several examples are hereinafter described with reference to the accompanying drawings which are of a diagrammatic nature.

Fig. 1 is a perspectiveview of a lounge or easy chair in accordance with the invention.

Fig. 2 is a cross sectional view of a modif-led form of easy chair.

Fig. 3 is a perspective View of a further modified form of easy chair.

Fig. 4 is a perspective view of a couch or settee in accordance with the invention.

Figs. 5 and 6 are cross sectional detail views of chambers applicable to the fabrication of armchairs, settees and the like articles of furniture.

Referring to Fig. 1 of the drawings, there is shown an easy chair comprising four envelope means, that is, one each for theV seat and back designated respectively by the numerals l andr 2, and tWo arm or side elements 3, and each comprises an outer cover of flexible but substantially 'inextensible material, for example, hide, woven fabric, or fabric-reinforced rubber, formed of united pieces or of one shaped piece as the nature of the material will allow. Each cover has -a slit opening 4, the openings in the seat unit l and Vside units 3 being located centrally underneath and that of the back unit 2 being located centrally at the rear. These openings serve for the insertion or removal of pneumatic inflatable tubes 5 preferably of rubber moulded to shape, these members 5 being only partially indicated by the appropriate dotted lines marked 5. Each member 5 has a 10 valve 6 located in an inconspicuous position and covered by a flap "l,v The openings 4 may be closed by lacing da or other suitable means such as sliding fasteners. After insertion of the inflatable tubes, the same are inflated to the re- 1 quired degree of pressure and the entire envelope means are assembled and connected together preferably in a readily detachable manner. As shown, the chambers are united by means in the form of flexible strips 8 having series of press button or the like connectionsY with the envelopes to be joined. It will be evident that further strips may be employed between the back, seat and side envelopes as desired and that various other modes of co-nnecting the chambers may be employed. These strips 8 act against the separating force of the air pressure in the separate sections or envelopes and are in tension; therefore they act as tie means for tying the adjacent parts together.

Fig. 2 shows an easy chair constructed of inl'latable envelopes simil-arly to the chair in Fig. 1 except that the seat and back are constituted by the same envelope meansll. A further difference consists in that the inflatable member or members consist of a sinuously disposed tube or tubes l0. The sinuous shape is ensured by means of stiffeners Il which may consist of padded members having enlarged inner ends Ila to prevent folds or creases in the tube or tubes l0. The stiffeners may constitute lateral stiifening stays and 4' the tube or tubes may have a fabric covering to limit the inflation thereof and to reinforce them against wear and puncture.' The sides of the chair may be inflated in similar manner by tubes.

The modied form of easy chair shown in Fig. 3 consists simply of an inflatable, flexible and airtight envelope shaped to assume the shape shown when inflated to the required degree. It may be made of any suitable exible material as previously specified, and preferably of fabricreinforced rubber. To prevent distortion andto hold the associated parts against separation under pressure flexible ties I2 are provided inside, these ties joining the edges of the seat portion withrthefside walls, the back and the bottom, it

' suitable core or packing I'I being readily understood that since the seat constitutes a re-entrant part of the inflatable envelope it will be liable to distortion on inflation. The valve 6 is provided at the rear. 'It will be readily seen that the inflatable chamber may be divided into separately inflatable chambers, each having a valve therefor. Obviously the airtight chamber will be of comparatively small bulk when deated. Y

Horizontal ties I2a extending from side to side and from back to front may also be provided as shown and also hold the associated parts against separation by the fluid pressure.

The settee shown in Fig. i is built up of side,

back and seat envelopes designated respectivelyV by the numerals 3, 2 and I similarly to the chair shown in Fig. Vl. Owing however,to the length of the seat chamber I, it is built up of substantially rectangular chambers I3 enclosed within `a suitable cover or envelope and suitably interconnected if necessary. The back unit 2 may obviously be built up of separate chambers in like manner. The envelopes I, 2 and 3 may be connected together as described with reference to Fig. l, or in any other suitable manner.

Fig. 5 shows an inflatable envelope or rectangular outer cover I4, and an inflatable endless tube I5 therein with the usual air valve I6. A is provided and the corners of any two rectangularly or similarly disposed surfaces of the cover I4 may be provided with packing I8 to prevent damage to the tube I5.

Fig. 6 shows an envelope in which the endless tube I5 being in part sinuously disposed around stiffeners or packing members II as previously described.

Several separate tubes may be disposed within said covers which may thus be of varying sizes and which can also be of widely differing shapes. By means of such inflatable envelopes many dif ferent articles of furniture may be built up, as

shown for example in Figs. l, 2 and 4, previously described. In the case of an article of furniture so built up, the inflatable tubes in all the envelopes or in groups of envelopes may be connected by a common tube having a valve therein so that all the chambers so connected can be blown ,up at once. Valves mayv also be provided between the inflatable tubes in each envelope and the common tube to prevent complete deflation on a puncture occurring in any envelope.

An armchair, settee or the like piece of furniture may comprise compartments in an outer cover capable of receiving inflatable inner members. SomeY such articles of furniture may be inflated under such high air pressure that practically a solid unyielding effect is obtained, any desired softness being given by the use of separate inflatable or other cushions. In other cases the air pressure may be such as to give a desired degree of resiliency.

Furniture made as Yhereinbefore described will be found an improvement on existingstructures.V

It can be stored in deflated condition or readily deflated for removal or cleaning. If made of rubber it will be hygienic and easily cleaned by washing. The improved furniture has theY further advantage that it is practically indestructible being therefore particularly suitable for hotel, ship and the like public use. Y

The chamber for use in constructing an armchair, settee or the like article of furniture as described may comprise an inflatable member enclosed in an unyielding canvas or equivalent cover to limit its expansion to a desired shape and size.
