Sept. 1, 1970 H. M. METZGER CHAIR Filed June 5, 1968 A W Q M u m 2% m M United States Patent 3,526,429 CHAIR Harold M. Metzger, Rte. 4, Box 3, Greenville, Ala. 36037 Filed June 5, 1968, Ser. No. 734,731 Int. Cl. A47c 3/029 US. Cl. 297-258 7 Claims ABSTRACT OF THE DISCLOSURE A balanced multipurpose rocking, reclining and lounging chair which, generally speaking, cannot overturn when occupied. A pair of spaced parallel symmetrical walls provide coplanar side frames and are marginally delineated to provide the butterfly design desired. Several angularly related pallet-like panels are fixedly suspended in the space between the side frames. The relatively narrow centralized panel fixedly supports a first horizontal cushion. The oblique angled upwardly forwardly inclined panel constitutes a bed or base for a proportionately long second but removable cushion. The oblique angled upwardly rearwardly inclined panel likewise supports the removable third cushion. The upper edges are primarily ornamental. The lower longitudinal edges are unique in that the parallel portions underlying the second and third panels and cushions are straight and are at right angles to each other while the intervening central portions are arcuately curved and provide rockers beneath the first cushion and panel on which it is fixedly bedded.

This invention relates, broadly stated, to chairs and seats and, while capable of being structurally enlarged to function as a couch for more than one person, is expressly designed and adapted to serve as a multipurpose rocking, reclining and lounging chair for a single occupant.

More particularly, the invention pertains to an adaptation whose primary component parts are wooden and wherein several related complemental but distinct cushioned seats are oriented and in fact are simultaneously combinable to provide at least four primary selectable positions for the occupant. By sitting anterior to the center on a seat cushion, an upright stationary seat is had. Sec ondly, by shifting ones body weight to a substantially centralized position the chair becomes a conventional-type rocking chair. Third, by intentionally shifting the weight to the center of the fixed first or central cushion, the occupant can cradle and nest himself in a relaxed comfortable positionnot unlike the position of a cradled astronaut prior to a flight inside a space capsule. In this attitude the occupants body reclines at minimized stress in a restful easy-to-nap manner. Fourth, by the simple maneuver of placing his hands behind his head when in the above-named position the chair and its occupant now P reclines to assume a maximum posterior tilted state thus locating the occupant in an antigravity or slant-board position such as is enjoyed by athletes and is recommended by physical culture advocates and enthusiasts. When the chair is empty, it is self-levelling and can assume a neutral horizontally balanced, but ready-to-use state, accessible from front or back (left or right) ends.

An ordinary rocking chair (not herein shown) and which embodies curvilineal or semicircular rockers lends itself to tilting and overturning either forwardly or backwardly as is well known. The innovation herein comprehended overcomes the stated hazard because of the fact that regular semicircular rockers are replaced by specially delineated floor engaging surfaces which are coordinated with special seating facilities thus making it virtually impossible to accidentally overturn the chair in either direction.

Briefly, the herein disclosed chair is characterized by two identical flat-faced wooden or equivalent walls disposed in spaced apart parallel relationship and providing companion side frames. The upper longitudinal marginal edges are delineated to define symmetrical selective armrests which, preferably but not necessarily, resemble butterfly wings. Each lower longitudinal floor contacting edge embodies a straight forward portion, a complemental straight rearward portion at right angles to the forward portion and an intervening portion which is curvilineal and of a predetermined arc. Accordingly, the central curvate portions provide rockers and the straight portions are tangential thereto and provide platform-type seating rests. Three cushions are provided; namely, a relatively narrow first or central cushion and forward and rearward oblique angled selectively usable cushions. The first cushion is normally horizontal and parallel to the floor when in its at rest unoccupied position. It is fixed atop a palletlike wooden or equivalent panel suspended between requisite portions of the end frames. The second and third (forward and rearward) cushions are removably based or bedded on properly inclined but fixedly mounted palletlike panels. The rearward cushion provides a backrest when the forward cushion is being used as a seat and vice versa.

To the ends desired and with a chair featuring the aforementioned capabilities it will be evident that the herein disclosed chair is unique in that by merely shifting body weight an occupant can automatically convert from a seat to a rocker, to a cradling recliner and when fully backward to a so-called health promoting slant-board.

In carrying out the principles of the desired concept the chair herein revealed has a permanent central cushion to the left and right of which are second and third longer cushions which have adjacent ends abutting and resting against the respective lengthwise edges of the intervening central or first cushion. These left and right cushions are insertable, removable and adjustable and are in line with the aforementioned forward and rearward straight edges. By occupying one of the removable cushions, either one, the other cushion comes into play as a companion backrest.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIG. 1 is a view in perspective of a multipurpose chair constructed in accordance with the present invention and showing the same in its normal or at-rest position.

FIG. 2 is a central longitudinal sectional view on an enlarged scale also showing the chair unoccupied and at rest.

FIG. 3 is a cross section taken on the plane of the section line 3-3 of FIG. 2, looking in the direction of the arrows.

FIG. 4 is a view in side elevation showing the chair with an occupant therein and properly seated to provide an ordinary type rocking chair.

FIG. 5 is a view also in side elevation and showing the occupant seated on the cushion at the right in a manner to provide an upright or stationary seat.

And FIG. 6 is a view also in side elevation and which shows the chair tilted over from right to left (compared to FIG. 5) and wherein the aforementioned anti-gravity or slant-board position of use is attained.

As is evident from the views of the drawing, the aforementioned sidewalls are preferably of uniform cross-sectional thickness from end to end and have flat interior and exterior vertical surfaces. These walls are identical in construction and the manner in which the marginal edges are delineated converts each wall into the desired butterfly shape. Alternatively, these vertical walls constitute the aforementioned elongated side frames. These side frames being alike in construction they are designated by the numeral 8 and each side frame is characterized by a forward end portion, a rearward end portion and an intervening companion central portion. The upper longitudinal edges of the side frames are delineated as at 10, 12 and 14 to define symmetrical selectively usable armrests. The terminal end portions 16 merge with coacting ends of the lower longitudinal specially designed edges 17. Each lower longitudinal edge embodies a straight forward portion 18, a straight rearward end portin 20 which is disposed at right angles to the lengthwise dimension of the straight forward portion 18. The adjacent ends of the portions 18 and 20 are joined by a curvilineal edge portion 22 which is of a predetermined arc or curvature. Accordingly, the central curvate portion in each instance provides a rocker and the straight edge portions 18 and 20 are tangential thereto.

Three cushions are provided and the first cushion 24 here referred to as the permanently mounted central cushion is relatively narrow and is superimposed on and supported by an underlying pallet-like panel 26 which spans the space between the central interior surfaces of the respective side frames 8 and has its respective ends suitably attached thereto. It will be evident from FIG. 2 that when the chair is in the normal unoccupied position (FIGS. 1 and 2) it is self-leveling and the then elevated panel 26 and cushion 24 assume a plane which is horizontal and parallel to the floor or other surface 28. The complemental cushion, the one to the right in FIG. 2 is designated as the upwardly and forwardly inclined cushion 30 and it is more specifically designated as the second cushion. It is approximately twice as long as the first cushion 24 is wide. It is removably based on a correspondingly long pallet or panel 32 which spans the space between the forward portions of the frames and which is securely mounted on suitably anchored angle irons 34. It will be noted that the lower end (FIG. 2) of this cushion 30 abuts the edge portion 36 of the first cushion 24. The correspondingly long and duplicate cushion 38 to the left of the control cushion is inclined upwardly and rearwardly and constitutes the third cushion. This cushion is slidingly supported on the pallet-like panel 40 which in turn is fixedly mounted atop the angle irons 42 secured to the interior sides of the rearward portions of the side frames.

It will be noted that the cushions 30 and 38 are at right angles to each other and that they are parallel to their respectively cooperable forward and rearward end portions 18 and 20 of the aforementioned longitudinal edges.

The self-balancing unoccupied position of the cradlelike chair is shown in FIGS. 1 to 3 inclusive. In FIG. 4 the chair is occupied and the occupant is shown using the same as a reclining rocker. At the right in FIG. the occupant is shown seated on the forward seat or cushion at which time the chair assumes an upright position and provides a stationary seat. At this time the edges 18 of the side frames are fiatwise atop the floor or other support surface 28. By resorting to the simple act of placing the hands behind the head the occupant and the chair can be caused to recline to the maximum posterior tilt, leaving the occupant in an antigravity or slant-board position as shown in FIG. 6 and which, as previously mentioned, is the contemplated position preferred by athletes and health enthusiasts. Due to the symmetry of construction the chair maintains the perfect balance in the neutral position in FIG. 2 when not in use.

Due to its simplicity of design and integral mechanical properties, the chair lends itself to maximum comfort to an occupant in any selected position.

By widening the space between side frames 8 the chair will serve more than one person. By widening side frames still more, the structure becomes a rocking-reclining couch (not shown).

By changing diameter of main arc and adjusting bisecting lines of the chair design, the size can be altered to accommodate children, adults or even oversized adults.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
