CHAIR STOOL, APPLICABLE TO DIFFERENT PURPOSES Filed April 30, 1959 United States Patent-Q 2,991,122 CHAIR STOOL, APPLICABLE TO DIFFERENT PURPOSES Jos Bar B60, Garcia Barbn 1, Vigo (Pontevedra), Spain Filed Apr. 30, 1959, Ser. No. 810,171 Claims priority, application Spain Dec. 20, 1958 3 Claims. (Cl. 297-3) This invention relates to seating arrangements, and more particularly to chairs adapted for performing various seating functions.

It is an object of the invention to provide an improved multi-purpose chair.

It is a further object of the invention to provide an improved chair wherein the back may be super-posed with respect to the seat, and thus provide a seating arrangement of higher elevation.

Another object of the invention is to provide, supplementary to the aboveindicated objectives, an arrangement whereby a chair may be tilted to side position,

whereat it offers both a seating and table arrangement.

A further object of the invention is to provide an improved chair which is readily and economically manufactured and which possesses inherently those features necessary to marketability.

To achieve the above and other of its objectives, the invention contemplates the provision of a chair wherein a back is pivoted to a seat for pivotal movement about an axis spaced from the plane of the seat. This back may then be pivotally superposed with respect to the seat, whereupon it constitutes a seating arrangement of higher elevation than said seat. Additionally, the invention provides, in operative association with said seat, two planar members which are substantially parallel to one another and which additionally are arranged substantially perpendicularly with respect to said seat. These planar members, when the chair is tilted to one side, constitute respectively a seating arrangement and a table arrangement.

As a feature of the invention, one pair of legs of the chair is constituted by members having the shape of a Z. This type of member is employed to support both said seat and one of said planar members.

Other objects and features of the invention will be apparent from the following description of a preferred embodiment thereof, as illustrated in the accompanying drawing, in which:

-FIG. 1 is a perspective view of a chair provided in accordance with one embodiment of the invention;

(FIG. 2 illustrates the chair of FIG. 1 in perspective, with the back pivoted downwardly and superposed with respect to the associated seat; and

FIG. 3 illustrates the chair of FIGS. 1 and 2 tilted to one side and providing a seating and table arrangement.

In FIG. 1 is illustrated a chair provided in accordance with a preferred embodiment of the invention. This chair comprises generally a seat 10, a back 12, legs '14 and 16,

legs

18 and 20, and

planar members

22 and 24.

Seat is a flat or planar member made of wood, cloth, rubber, plastic and the like, or any combination thereof, this member being generally of conventional form and being provided with laterally disposed loops 26 preferably arranged so that they depend downwardly from the seat. Seat 10 is pivoted between

legs

14 and 16 by means of a shaft 28.

The back 12 of the chair consists generally of

frame members

30, 32 and 34, conventionally interconnected and supporting a cloth or plastic backing member 36 which is also provided in conventional manner.

A shaft 38 is provided, by means of which the back '12 is pivoted to the tops of

legs

14 and 16. This, in efiect,

couples back 12'pivotally to seat 10. Shaft 38 is spaced from the normal horizontal plane of seat 10, such that when the back 12 is pivoted forwardly, as illustrated in FIG. 2, the backing portion 40 of back 12 constitutes a second seat, the elevational level of which is higher than that of the seat 10.

It will be appreciated that the dilference in elevational levels may be selected at will for the design of a chair provided in accordance with the invention. Thus, although the difference in elevational levels illustrated in IFIG. 2 is constituted by the width of

frame members

30 and 32 in the illustrated embodiment, along with the position of shaft 38, it is to be understood that these dimensions can be regulated at will so that significantly different elevational levels may be provided.

As illustrated in the drawing, and particularly in FIG. 3, legs -18 and 20 are Z-shaped. These legs each consist of a section 42 which is accommodated in loops 26 of seat 10, a section 44 which is pivoted to

legs

14 and 16, as indicated by pivot 46, and a section 48 the extremity of which supports, in part, the substantially planar member 24, the other end of which is connected between

legs

14 and 16. It will be appreciated from the shape of

elements

18 and 20 that the structure of the invention is readily and economically manufactured so as to meet the requirements of marketability.

In the tilted position of the chair illustrated in FIG. 3,

members

22 and 24 constitute respectively a chair arrangement which, for example, may be straddled and a table arrangement operatively associated with the chair arrangement. Thus, for example, one who is sitting on the element 22 may use the element 24 as a table for eating, typewriting, and so forth.

The materials from which the various elements of the chair of the invention are constructed may be conventional materials. These materials will, however, preferable be lightweight, so that the chair can be readily manipulated as intended.

To facilitate the use of the chair in any of the illustrated positions, the chair is provided on the one hand with supporting

members

50, 52, 5'4 and 56, which support the chair in the position illustrated in FIGS. 1 and 2. The chair is also provided with supporting

members

58, 60 and 62, and with another supporting member (not shown), which support the chair in the position illustrated in FIG. 3

There will now be obvious to those skilled in the art many modifications and variations of the structure set forth. These modifications and variations will not, however, depart from the scope of the invention, as defined in the following claims.

What is claimed is:

1. A chair comprising a seat, legs supporting said seat, a back pivotally connected to said seat for pivotal movement about an axis spaced from said seat whereby said back may be superposed with respect to said seat so as to constitute a seating unit of higher elevation than said seat, and spaced substantially parallel planar members supported by said legs and arranged substantially perpendicularly to said seat and beneath the latter in staggered relation, said planar members constituting respectively a seating unit and a table with the chair tilted so that said seat is positioned in a vertical plane.

2. A chair as claimed in claim 1 wherein said legs are constituted by crossed members arranged in pairs, each of said pairs of crossed members including one member having a Z-shaped configuration and being adapted for supporting in part both said seat and one of said planar members.

3. A chair as claimed in claim 2 comprising supporting members on said legs in two mutually perpendicular 3 4 planes and adapted for supporting said chair with said seat 1,010,086 Steele Nov. 28, 1911 in horizontal position and with said seat in a vertical 1,024,192 Florian Apr. 23, 19 12 position- 1,222,673 Rizzo Apr. 17, 1917 References Cited in the file of this patent 2,588,574 Rizzolo Mar. 11, 1952 UNITED TA PATENTS 5 2,749,972 Markkula June 12, 1956 483,810 Nesmith Oct. 4, 1892
