FIGURE 6 is a view similar to FIGURE 4 but show

Referring more speci?cally to the drawing, the folding
rocking chair in its entirety is designated generally 8 and
includes a folding chair, designated generally 9, and a
rocker unit, designated generally 10.
The folding chair 9 is of conventional construction, of
the type normally used out—of-doors on porches, patios,
lawns and the like, lhaving a frame 11 formed primarily
of lightweight tubular metal such as aluminum, including
U-shaped members 12 and 13 having substantially parallel
side portions 14 and 15, respectively, forming the front
yond the other shorter upper leg or bill 44 of said hook
shaped member. The hook members 41, like the strap
members 37, are disposed in transverse alignment to one
another, and are spaced from the arch portions 38 of the
strap members 37 a distance corresponding to the spac
ing between the rear cross member 17 and the front cross
member 16 of the legs 15 and 14, respectively. Thus,
when the chair 9 is extended the front cross member 16
will engage in the rearwardly opening hooks 41 and will
be mounted on forward portions of the rocker elements
31 and 32, so that the rocking chair 8 may be utilized
in a conventional manner.
In order to fold or collapse the rocking chair 8, the
seat frame 18 is swung upwardly about its pivot 19 and
the back rest frame 21 is swung forwardly, causing the
ends by the intermediate portion 16 of said member 12,
arm rests 22 to swing upwardly about their pivots 23,
and the lower ends of the two rear legs 15 are similarly
the links 27 to swing downwardly and rearwardly

It will also be readily apparent that the rocker unit 10
may be attached to folding chairs wherein the front and
rear cross members are not integrally connected to the
front and rear legs, respectively, and wherein said cross
members may be spaced short distances from the lower
ends of the legs.
FIGURE 6 illustrates a slightly different form of the
tion or scope of the invention as hereinafter de?ned by
the appended claim.
We claim as our invention:
A rocker unit for use with a folding chair of the
type having a rear cross member connecting lower por
tions of the rear legs and a front cross member connect
ing lower portions of the front legs of the chair, com~
pletely detached from the chair 9 when the chair is moved 20 prising an elongated rigid rectangular frame having cor
rocker unit, and wherein the rocker unit may be Corn—
to a folded or partially folded position.
The rocker unit of FIGURE 6 differs from the rocker
unit 10 of FIGURES 1 to 5 only in that the connecting
members or straps 37 are each replaced by a connecting
member or strap 45, one of which is shown. The strap
45- has a rear end portion 46 shown disposed on and
secured in any conventional manner as by means of a
fastening 47 to the upper side of the rocker element 32',
which corresponds to either the rocker element 32 or 31..
The strap member 45 has an upwardly bowed intermedi
ate portion 48 which is disposed forwardly of the secured
rear end 46 and which engages over the rear cross mem
responding transversely spaced sides forming rocker ele<
ments, said frame being bowed longitudinally from end
to-end thereof to provide a concave upper side and a
convex underside, a pair of transversely aligned rear hook
members secured to upper sides of the rocker elements
adjacent a rear end of the frame and including for
wardly extending resilient hook portions yieldably dis
posed relative to said rocker elements and adapted to
yieldably engage over said rear cross member, between
said rear legs, for connecting said rear cross member
pivotally and detachably to the frame, and a pair of
transversely aligned front connecting members secured
to the upper sides of said rocker elements adjacent a
ber 17, and an upwardly turned forward free end 49‘. The
forward end of the frame and comprising rearwardly
