Patented Aug. 29, 1950 UNITED STATES PAIENTQOFFICE i1 I 2,520,741 Y v SWINGING LAWN m Ransom z. sneu, Miami; Fla. Application April 1. 1946, Serial No. 658,769"

' 1 'Claim.

wThis invention relates to improvements in chairs. More particularly, the invention relates to a swinging chair.

The primary object of the invention is to provide a chair which is novel, simple and sturdy in construction, which is comfortable, and which is particularly well suited for use outdoors. H

A further object is to provide a swinging chair which is provided with a foot rest to enhance the comfort thereof and facilitate rocking thereof, said foot rest being retractible to a position permitting ease of access to and egress from the chair.

- A further object is to providea swinging chair comprising a supporting unit and a seat unit provided with arm rests, wherein said arm rests arepivotally connected to said supporting unit to rockably'suspend said seat unit in said supporting unit.

Other objects will be apparent from the description and appended claim.

In the drawing:

Fig. l is a side view of the chair.

Fig. 2 is a front view of the chair.

Referring to the drawing, which illustrates the preferred embodiment of the invention, the numeral l designates the supporting unit of the chair. The supporting unit comprises a pair of rigid side members I2, preferably formed of metal, such as metal tubing. The side members are bent in substantially U-shape, and are positioned inverted with their ends mounting suitable bearing feet or plates [4. The side members are interconnected adjacent their lower ends by cross braces Hi. It will be understood that any additional braces or reinforcing members found desirable or necessary to strengthen and rigidify the supporting unit may be incorporated therein. The swinging seat unit I8 of the chair has a rigid frame member formed of metal tubing or other suitable material. The frame is bent in substantially U-shape with its end portions bent out of the plane of the U. The central or intermediate portion of the frame is of a length less than the spacing of the side members l2 of the supporting unit and preferably extends substantially horizontally. The side portions 22 extend forwardly from the central portion 20 in substantially horizontal position and are pivotally connected at 24 to the top central portions of the side members of the supporting unit. The end portions 26 of the frame member are bent forwardly and downwardly and terminate spaced above the surface on which the supporting unit rests. Arm rests 28 are secured to the side poror bars 32 bent longitudinally to provide a seat portion and aback rest portion. The front lower endsof-the bars 32 are secured to a cross bar, 34 which'extends between and is secured at its ends tothe depending portions 26 of the frame. member-spaced above the ends thereof. illustrated, the crossbar 34 is positioned at ;a level at: substantially mid-height compared .to the-levelof the pivotaxes 24. The seat mem berextends rearwardly and then upwardly to;

besupported byicentral portions 20 of the frame member spacedbelow its upper end. A second 5 ba .5. o n ctedto the. upper -.0 1; the bars 32.

It will be understood that the seat member may be constructed in many difierent ways and from different materials as is well understood in the art, as for example from a single unitary bent sheet metal panel or from a rigid marginal frame and a sheet of cloth or other flexible material secured to and supported by the frame. In each instance the seat unit is supported and positioned by the pivoted frame member at spaced points on opposite sides of the pivot axes 24.

be noted that the spacing of the outer edge of the foot rest 46 from its pivot 44 is slightly less than the spacing of cross bar 34 from pivot 44, thereby insuring that the foot rest will not interiere with the seating of a user on the chair while the foot rest is retracted. A pair of elongated flexible members 46, such as chairs, cords, cables or the like, are secured at their upper ends to the supporting unit, as at pivot members 24, and at their lower ends to the opposite ends of the foot rest. Members 43 serve to limit the forward movement of the foot rest from its retracted position and to position said foot restat an angle or inclination conducive to the comfort of the user of the chair.
