CONVERTIBLE CHAIR.

Application filed March 10, 1924.

To all whom it may concern Be it known that I, Gonnox Axons Ross common, a subject of the King of Great Britain, residing at 27 Gainsborough Road, hadwell Heath, Essex, England, have inrented new and useful Improvement in G011- vertible Chairs, of which the following is a specification.

This invention relates to articles of furniture and refers more particularly to articles of furniture which can be used for a definite purpose and can be converted to form another article so as to be useful for a different purpose.

The movable portion of the chair is advantageously constituted by the seat and back of the chair.

In one constructional embodiment of the invention the improved article of furniture regarded as a chair comprises four legs and top and bottom skeleton frames one of which serves as a base when the article is being used as a chair and both of which are adapted to act as supports and end walls when the article is turned into position to form a cot. The chair legs are connected pairwise by cross slats to form the two sides and bottom of the cot and a portion of the top skeleton frame is formed as a movable tray or support for the babys toys or the like. The seat portion is pivoted or hinged to or near to the two front legs and the back por tion is pivoted or hinged to the seat portion the arrangement being such that when it is desired to form a cot the article is turned so as to be supported on the top and bottom skeleton frames and the seat portion turned on its pivots or hinges so as to form a part of the bottom of the cot the back of the seat portion forming the end of the cot.

In order that the invention may be clearly understood and readily carried into effect I will now describe the same more fully with reference to the accompanying drawings which illustrate several structural embodiments of the invention.

In these drawings:-

Figure 1 is a side elevation of one form of my improved article of furniture serving as a babys chair.

Figure 2 is a side elevation of the same article converted into a babys cot.

Figure 3 illustrates a slightly modified form.

Figures 4 and 5 illustrate two further constructional forms having. expanding Serial No. 698,321.

sides. Figure 4 illustrates the article actually serving as a cot.

The so-called chair-cot has four legs as usual, a top skeleton frame 1 formed with a movable tray or support 2 for the babys toys or the like, and a lower skeleton frame 3 serving as a base. The legs are suitably braced or stayed pairwise as to three pairs to constitute the two sides and bottom of the structure when acting as a cot as in Figures 2, 4 and 5. The forward ends of the side members of the bottom frame 3 are preferably provided with wheels, rollers, castors or the like 4 to facilitate moving the structure about either as a chair or as a cot.

5 is the seat portion and 6 the back of the chair these parts being hinged together at 7 and the seat being hinged to the top front cross stay at 8 or alternatively pivoted by means of bolts running through the main frame front legs at 8. 9 is a pad on the back of the chair which is attached to the top back cross stay by a hook or the like at 1.0. From inspection of the drawings it will be readily seen that the chair is converted into a cot by swinging the parts 5 and 6 into their alternative position in which the free end of the chair back is again attached to the top back cross stay by a hook 11 or the like. Obviously instead of hooks any other convenient looking or fastening devices may be used. As will be readily understood the top and bottom skeleton frames of the chair become the end walls and supports of the cot.

A three piece hinged mattress 12, 13, 14. may be attached to the bottom of the cot by means of tapes, clips or other suitable fastenings so that when the cot is required to be converted into a chair this mattress may be folded over and remain within the chair. The enclosed space formed by the hinged mattress when folded may be suitably utilized to contain the childs pillow, bedclothes and the like.

It is to be observed that the seat 5 projects beyond the front cross stays and beyond the rear edge of the tray 2 to ensure the babys being retained on the seat. Figure 3 illustrates a slight modification in which the seat does not project much but the tray 2 extends back over the seat to a considerable extent represented bv the hinged portion 2', the function of the overlap being the same as in Figures 1 and 2. In converting the chair snown in Figure 0 into a cot the hinged portion 2 of the tray is folded back, and the seat is swung about pivots or trunnions 15 constituted by bolts passing through brackets or angle pieces 16 and through corresponding brackets extending downwardly from the underside of the seat.

In Figures i and 5 two ways of expanding the cot laterally are illust ated by way of example. In Figure at the sides of the cot are shown attached to the main structure by toldable arms 17' whilst in Figure 5 the sides are shown as constituted by cranked stays 1S and bar 19 the latter being in tact a back leg of the structure when serving as a chair. The entire row of cranked stays can swing outwards about their respective sockets and thereby add width to the cot, as will be readily understood. When in opened position the sides are held in any suitable manner, "for example, by red 20 and angle iron 21.

hen laterally expansible sides are employed as shown in Figures 4 and 5, the longitudinal bars or trout chair legs may be duplicated and cross braced to increase the strength.

It extra length is required the end wall at the toot of the cot that is to say the chair back portion of the structure can be let down from the position shown in Figure 2 into a horizontal position and be supported from the floor by a folding leg. This extension may receive an extra section of the mattress or the pad on the seat back may be detachable and be used as a mattress extension.

It will be understood that the above de scribed constructions are not to be regarded as limiting the invention thereto but as i11- dicatiug only the manner in which the invention may be carried into effect. Also am suitable material may be used in manuhicturing the so-called chair-cot, as for example entirely square or round wood bars etc. or tubular metal or partly wood or partly metal.

llhat I claim is 1. An article of furniture convertible at will into a ba cot or a chair comprising a framework, :1 chair-seat member hinged at its front edge to said framework, a chairhack member hinged at, its lower edge to the rear edge oi said chair-seat member and means for supporting said members in alternative chair-functioning and cotfunctioning positions, so that the desired conversion may be effected.

2. An article of furniture convertible at will into a babys cot or a chair comprising legs braced pairwise as to the front pair and the two side pairs, a seat member hinged as to its torepart to a cross brace of the front legs, a back member hinged to the rear part or" said seat member, means for supporting said members in alternative chair-functioning and cot-functioning positions and means whereby the article may be expanded laterally when functioning as a cot.
