Description:

The invention relates to an article of furniture, and more particularly to an easy chair of a construction making it possible to dismantle such chair into a substantially complete knockdown condition so that the component parts thereof may be packed in a relatively small space for transportation or storage. Such knockdown easy chair is also so constructed that after it has been assembled, the inclination of the back rest may be adjusted.

A particular object of the invention is to provide such knock-down adjustable easy chair in the assembly or disassembly of which no special skill or tools of any kind are required. The novel construction of my chair is of an all wood construction having a small number of parts which are detachably secured together in the assembled condition of the chair, and yet provides a structure in which there is a rigid and durable connection between all component parts without any possibility of loosening of joints in the ordinary use to which such a chair is conventionally put.

My novel knock-down adjustable easy chair may also be produced in large quantities in accordance with modern mass production methods, the component parts being of simple design and readily interchanged, as they do not involve precision tooling, precision measurements, or other manufacturing-cost raising factors.

In its broadest aspects, my novel knock-down adjustable easy chair comprises a pair of vertically disposed supports of angular shape, the two vertical sections of each of such supports constituting the legs of the chair and the central horizontal sections constituting the side arms of the chair. These two supports are connected by suitable cross-pieces, and the seat and reclining back-rest portion of the chair is disposed between the two supports upon a pair of guide rails extending between the front and rear leg sections of the supports.

Particular features of novel construction are incorporated in the two connecting members extending between the supports and so connected to the rail members and to the supports as to insure a ready and easy attachment of the component parts of the chair and yet produce an extremely rigid and durable structure when the chair has once been assembled.

A particular embodiment of my invention is illustrated in the accompanying drawings, in which Fig. 1 is a perspective view of an adjustable knock-down easy chair constructed in accordance with my invention; Fig. 2 is a view of the component parts of the chair assembly without the seat and back-rest, showing the relative disposition of the various parts in the course of the assembling of the chair; Fig. 3 is a perspective view of the assembled chair with cushions applied to the seat and backrest portions thereof; Fig. 4 is a side elevation of the chair showing the manner in which the back-rest may be adjusted to various angular positions; and Fig. 5 is a plan view showing the component parts of the chair placed within the small space necessary for securely wrapping and packing the same for transportation or storage.

Referring more particularly to the drawings, in which similar reference characters identify similar parts in the several views, 10 and I are respectively the right and left hand supports preferably formed of strips of lumber, one section 12 of which constitutes the rear leg, the other section 13, the front leg, and the horizontal intermediate section 14, constitutes the arm-rest of the chair. The sections 12 and 13 forming the legs of the chair, are connected to the central arm-rest 14 in any suitable manner, for instance, by the glued half-lap joints 15. The sections 12, 13 and 14 may be constructed of comparatively narrow strips of wood or plywood of suitable thickness or even of composition material.

In the assembling of the chair, the two rear leg sections 12 are joined together by a rear back-rest rail member 16 which may be formed of a strip of wood having a chamfered surface 17 extending along its top front edge. The back-rest rail 16 is connected to the back legs 12 by means of a pair of dowels 18, one at each end of the back-rest rail, said dowels extending through correspondingly provided apertures in the back leg members 12. The dowels 18 are of the half-split type.

Besides the back-rest rail 16, rigid connection of the two back leg members 12 is obtained by the cross supporting rail 19 which is of somewhat heavier construction than the back-rest rail 16, but is cut out near its end sections to abut against the surface of the back leg sections 12 at a point somewhat below their center, and at which point two dowel receiving apertures 20 are provided to correspond with similar dowel receiving apertures 21 in the end sections of the cross rail 19. As the cross rail 19 is placed in position, dowel pins 22 are passed through the respective apertures 20 and 21, the dowels providing a rigid and substantially durable and strong connection between the leg sections and the cross rail 19.

It will be noted that the cross rail 19 is recessed as at 23, 23 for purposes hereinafter described.

A substantially similar type of cross supporting rail 24 connects the front leg sections 13 of the chair, the end portions of such front cross rail being also cut away sufficiently to accommodate the thickness of the front legs 13, dowel receiving apertures 25 being provided in the end sections of the front cross rail to cooperate with dowel receiving apertures 26 in the front legs to receive pairs of dowels 27 which are likewise of the half-split construction, and may preferably have decorative heads 28.

The front cross rail 24 is likewise recessed at 29, 29. These recesses, together with the recesses 23, 23 in the rear cross rail 19, are of precisely the width to receive the ends of two slide rails 30, fitted between the front and rear legs of each side support of the chair. It will be noted that such slide rails 30 are of substantially L-construction turned toward each other with the lower portions of the L-structure fitting snugly and firmly into the recesses 23 and 29 of the cross rails 19 and 24, respectively. It will be noted also that the slide rails 30 are fitted snugly into the recesses 23 and 29; they are also in rigid frictional contact with the adjacent surfaces of the back and front leg sections.

The entire structure thus assembled by means of the various dowels and the recessed cross rails and fitting slide rails, will have a rigidity and strength of connection of the component parts of my knock-down chair not ordinarily attained in the conventional structure of this general type of furniture.

The seat portion of my novel knock-down chair is constituted of ar substantially rectangular frame member 31 having a plurality of transversely extending slats 32 secured therein in any suitable manner, for instance, by extending the ends of such slats into recesses provided in the side members of the frame. The entire seat frame 31 is positioned for sliding movement thereof upon the slide rails 30, so that the frame may readily slide upon the horizontal sections of such L -shaped slide rails between the vertical sections of such slide rails.

At the rear ends of the seat frame 31, are provided a pair of substantially wedge-shaped wooden hinge members 33 having horizontal apertures passing therethrough in which are rotatably positioned pins 34 extending from the lower ends of a back-rest 35. The members 33 act as hinges or fulcrum supports for the backrest 35 which may be adjusted to a plurality of angular positions thereof with its back surface resting upon the chamfered edge 17 of the backrest rail 16 by the proper disposition of the suitable one of a plurality of blocks or adjusting cleats 36 provided upon the lower surface of each side rail of the'seat frame 31 rearwardly of the front cross rail 24.

It will be seen from Fig. 4, in which one position of the back-rest 35 is shown in full lines and another position thereof in dotted lines, that a plurality of inclinations of such back-rest may be secured, depending upon which of the plurality of cleats 36 is positioned just rearwardly of the front rail 24 so as to abut thereagainst.

In the particular embodiment illustrated, three such adjusting cleats 36 are shown, but, of course, any number of such cleats may be used.

In Fig. 3 I have illustrated my easy chair in its fully assembled condition with a cushion 37 upon the seat portion, and a cushion 38 which may conveniently be disposed against the surface of the back-rest 35.

In Fig. 5 the component parts of the easy chair just described, with the exception of the cushions 37 and 38 and the cross slats 32 omitted from the seat frame 31, are shown to illustrate the manner in which such component parts may be compactly packed in a small space for transportation or storage. The blocks 39 appearing in Fig. 5 adjacent the inner faces of members 33 are blocks glued on the back face of the back rest 35 to give such back rest thickness to receive the pins 34.
