This invention has for its object the provision of a chair of the folding type which will support a person either in a sitting position or in a reclining or sleeping position, and particularly to devise a chair of this type in which the user may shift from the one position to the other while remaining upon the chair.

A further object is to devisea chair of this type which is comparatively inexpensive and easy to assemble, which is light in weight, and yet sufficiently strong for all ordinary purposes.

A further object is to devise a chair which may be opened from the folded to the sitting or reclining position and vice versa with a minimum amount of manipulation and effort.

A still further object is to devise a chair which may be shifted about from place to place by the user or other person while the user is on the chair.

I attain my object by means of the construction hereinafter described and illustrated in the accompanying drawings in which:

Fig. 1 is a detailed side elevation of a chair constructed according to an embodiment of this invention; 1

Fig. 2 is a longitudinal section taken vertically through the chair, showing the chair in full reclining position;

Fig. 3 is a sectional view taken on the line 33 of Fig. 1;

Fig. 4 is a fragmentary sectional view taken on the line 3-4 of Fig. 2;

Fig. 5 is a fragmentary sectional view taken on the line 55 of Fig. 2;

Fig 6 is a fragmentary side elevation partly in section of the forward portion of the chair;

Fig. 7 is a fragmentary sectional view taken on the line 1-1 of Fig. 3;

Figure 8 is a detail side elevation, partly broken away, of the chair in folded position, 7

Figure 9 is a fragmentary longitudinal section of the rear portion of the chair in folded position.

In the drawings like numerals of reference indicate corresponding parts in the different figures.

The chair is provided with two side frames, each comprising an arm rest I secured to a top bar Ia having a front leg 2 pivoted adjacent its front end and a rearwardly and downwardly inclined rear leg 3 has its upper forward end pivotally connected with the top bar la. A'link 4 having one end pivotally connected with the rear leg and its other end pivotally connected with the front leg 2 provides for unitary swinging of the front and rear legs together. A stop 8 is provided at each side to limit the forward movement of the frontleg 2.

A cross bar -5 extends between the front legs of the two side frames, while a cross bar 1 extends between the two rear legs, and a cross bar 6 between the two links 4 and through the rear legs 3.

With the arrangement described the legs of the chair'may be moved in unison to open or folded position as described.

Positioned between the side frames is the back frame 13 which comprises side members 9 pivoted at it to the top bars Ia adjacent the rear thereof. The upper ends of the side members 9 are connected by a cross bar I I. Pivotally supported from the lower ends of the side members is the rear end of the seat frame C, which comprises side members l2, the forward cross bar l3 and the rear cross bar M.

The forward end of this seat frame is Pivotally connected intermediate the ends of links [5, the upper ends of which links are pivoted adjacent the forward ends of the top bars Id of the side frames A. The lower ends of these links I5 are connected by a cross bar I6 and the links l5 are spaced apart a'distance less than the distance of the front legs 2 so that the lower portions of these links will strike the cross bar 5 when the chair is being collapsed in order that the links 2 and 3 will move in unison with links l5 to collapsed position.

To complete the seat a strip of webbing H extends transversely between the side members [2, while a second or" longitudinal strip of webbing I8 extends from the rear cross bar [4 over the transverse webbing I1, over the front cross bar [3, and has its other or forward end connected with the cross bar It.

To complete the'back, two vertically spaced strips of webbing l9 and 20 extend transversely between the side members 9 of the back frame B, while a second strip of webbing 2! extends longitudinally of the back frame, its, upper end being connected to the cross bar II and its lower end fixed to the lower transverse strip 20.

Pivotally mounted on the lower ends of the links I5 is a foot rest D, which comprises side members 22 and a cross member 23. The side members are provided with stops 24 which engage the rear of the links [5 to limit rocking of the foot rest when the chair is in reclining position.

. Secured to theunder side of the side members 12 of the seat frame behind the legs 2 is a trans verse leg extending and safety bar 30, which bar projects laterally of the side members [2 far enough to engage the rear surface of said legs. To fold the chair, it is simply necessary to hold the upper part of the back frame with one hand and lift the forward end of one side frame with the other hand, and all the parts, with the exception of the foot rest, automatically move to the folded position. The foot rest may be moved into folded position by a secondaryoperation.

To open the chair, the upper end of the back frame is held with one hand and the arm rest I gripped with the other hand, and by pulling the latter away from the back the parts of the chair will automatically move to the extended position. In this case the foot rest requires a secondary operation to move it to position for use. My improved chair may also be used by cone valescents, and in this case it is desirable that the chair may be moved from place to placewithout the patient getting off. The lower cross-bar 6 is therefore preferably. formed. as an axle and has around wheels 25 thereon, whilecasters 26 are mounted on the lower ends of the front legs 2'. To enable an attendant tohmove the chair with the patient thereon, the side members 9 of the back frame are provided with extensions 9 which may be used as handle grips.

To enable the patient to move the chair from place to place while sitting orv lying thereon, I provide the following means. On the extended ends of cross bar 6. ground wheels 25am rotatably mounted and a grooved pulley Z'lis fixed relative to each ground wheel 25 An endless belt 29 is trained over pulley 2'1, and over a second grooved pulley 28 rotatablymountedon the pivot between the legs Eand links 4. By operating the belt 29 or pulley 28, the ground wheels may be rotated to move the chair as desired.

An important feature of the present invention is the ease with which the chair may be opened and folded. This is largely du to the interconnection of the parts andvparticularly the relationship between the front legs 2 and their connecting cross bar and the extension of the links 45. below the front end of the seat, which extensions are adapted toiengage and be engag d by cross bar 5. It will thus be seen thatas the legs 2 are swung downwardly and forwardly from a collapsed to an extended positioncross bar 5 will strike links l5 and swing the latterto extended position. Legs 2 are at this time engaged by the extended ends of bar 30 as the seat frame swings downwardly and forwardly so that the connectedlfront andrear legs will move to -extended position at the same time that th back is swung. upwardly and rearwardly. he legs are: moved to completely extended position b rocking the back downwardly to sleeping. position as shown in Figure 2. Inthe event the front legs are not moved to completely extended position as shown in Figure 1, but are disposed in downwardly and rearwardly'incl-ined position,,the legs are held against collapsing by engagement with the ends of safety bar 30-. While this latterposition is not the proper extended position. of the legs, nevertheless the chair will function as such with the legs only partly'extended.

It will also be noted that the fabric of the seat frame and fabric of the back are unconnected, and that the seat frame; with its fabric, extends considerably to therear of the pivotal connection with the back frame side members; This is also important in providing a comfortable chair.

Having. regard to the foregoing disclosures, the

patent of which this specification forms part confers, subject to the conditions prescribed in the Patent Act, 1935, the exclusive right, privilege and liberty of making, constructing, using and vending to others to be used, the invention as defined in claims submitted by the patentee as follows.
