Description
My invention relates to new and useful improvements in patio or
garden furniture and is directed to furniture of this type which is
light-weight, rugged, inexpensive and easily convertible to several
forms such as stools or bar stools or tables and which may be
readily disassembled and stacked for storage purposes.
Herein a the smaller light weight plastic such as polypropylene is
employed to produce knock-down furniture of the type described
which will withstand the abuses of outdoor use and which may be
easily cleaned with a damp cloth.
As a novel feature of the invention, I provide a plurality of
identical mating parts which can be assembled to form tables or
stools with a minimum of effort and without the use of special
tools.

FIG. 11 is a cross-sectional view of a plurality of the half-parts
in stacked or stored position.
Referring first to FIG. 1, a table 10 comprises a top 12 supported
by a pedestal 14, the top and pedestal preferably being formed from
a high impact, light-weight plastic material such as polypropylene
or the like.
The pedestal comprises a pair of identical half-parts 16 in the
form of truncated cones, one being inverted relative to the other,
the two being releasably interlocked together in manner to appear
and each including a main body portion 18 having tapered walls
which flare outwardly to merge with a base 20 which in turn flares
outwardly and merges with an upstanding outer rim or wall 22, which
serves either as a support which rests on the ground or floor, or
as a support for top 12.
The top is assembled to the pedestal by means of a central locking
ring 24 which depends from the lower surface of the top and is
inserted into the open upper end of the upper half-part 16 and is
engaged with outer rim 22 thereof in the manner of a snap fit, as
shown in FIG. 1.
The same top may be used to form the smaller table 10' shown in
FIG. 2, the top being supported by a pedestal 14' comprising a pair
of identical half-parts 16' in the form of truncated cones, one
being inverted relative to the other, the two releasably
interlocked together in manner to appear and each including a main
body portin 18' having tapered walls which flare outwardly to merge
with a base 20' which in turn flares outwardly and merges with an
upstanding outer rim or wall 22', which serves either as a support
which rests on the ground or floor, or as a support for top 12.
The top is assembled to pedestal 14' by means of an inner locking
ring 24' which is concentric with central locking ring 24 and
depends from the lower surface of the top, the inner locking ring
24' being inserted into the open upper end of upper half-part 16'
and being engageable with outer rim 22' thereof in the manner of
snap fit, as with the FIG. 1 embodiment.
Except for smaller smalaler size of the pedestal 14', which
necessitates association with the inner locking ring 24' of the
top, the tables 10 and 10' of FIGS. 1 and 2 are identical.
The half-parts of pedestal 14 also serve as a pedestal for a bar
stool 30 shown in FIGS. 4 and 5, wherein a seat 32 is substituted
for the table top 12 and a foot support 34 is associated with the
lower half-part 16 of the pedestal.
Seat 32 comprises a disc-like upper wall 36 having a depending
peripheral wall 38 which is inserted over the outer rim 22 of upper
half-part 16 and is engageable with said outer rim in the manner of
a snap fit.
A stop bead 40 on the inner face of peripheral wall 38 of seat 32
is engageable by the upper end of outer rim 22 of the upper
half-part to preclude jamming of the parts.
Foot support 34 is sleeved on lower half-part 16 and includes an
inner ring-like hub 42 which slopes outwardly from top to bottom so
as to be complemental to the tapered wall of main body portion 18
of the lower half-part.
An outer ring 44 is disposed concentric to hub 42 and is supported
in spaced relation thereto by a plurality of equi-spaced upright
webs or fingers 46 which radiate outwardly from the hub and are
fixed at their outer ends to the inner surface of the outer
ring.
Referring now to FIGS. 6 and 7, the half-part 16' of pedestal 14'
also serve as the pedestal for a stool 50', wherein a seat 52' is
substituted for the table top 12.
Seat 52' comprises a disc-like upper wall 54' having a depending
peripheral wall 56' which is inserted over the outer rim 22' of
upper half-part 16' and is engageable with said outer rim in the
manner of a snap fit.
A stop bead 58' on the inner face of peripheral wall 56' of seat
52' is engageable by the upper end of outer rim 22' of the upper
half-part to preclude jamming of the parts.
As aforesaid, except for the matter of size, the half-parts 16 and
16' are identical, wherefore, only one thereof will be described in
detail.
Each half-part includes a tapered recess 50 which extends inwardly
into the main body portion 18 at one side thereof and a
complemental tapered projection 52 which extends outwardly from the
main body portion at an opposite side thereof.
A flat, upright central wall 54 which extends into the main body
portion 18 and extends outwardly therefrom is common to both the
recess 50 and the projection 52.
Recess 50 additionally includes a tapered wall 56 which extends
inwardly from the outer end of main body portion 18 and is curved
to form a tapered semi-circle which terminates at each end at
central wall 54. The recess terminates in an innermost base wall 58
which extends between the inner end of central wall 54 and the
inner end of tapered wall 56, the base wall having a central
opening 50 therein.
Projection 52 additionally includes a tapered wall 62 which extends
outwardly from the outer end of the main body portion 18 and is
curved to form a tapered semi-circle which terminates at each end
at central wall 54. The projection terminates in an outermost apex
wall 64 which extends between the outer end of central wall 54 and
the outer end of tapered wall 62, the apex wall having a centrally
located upright finger 66 extending outwardly therefrom.
Finger 66 is of suitable size and configuration so as to be freely
receivable in the central opening 60 of the recess 50 of another
half-part when two half-parts are inverted and mated in telescopic
manner, with the projection 52 of one half-part being receivable in
the recess 50 of another half-part.
Each recess 50 has a plurality of curved locking ribs 68 on tapered
wall 56 which are engageable with similar curved locking ribs 70 on
tapered wall 62 of projection 52 when the half-parts are mated to
releasably lock the half-parts together.
Locking ribs 72 are provided on the outer face of the central wall
54 for like purposes.
As best seen in FIGS. 5 and 9, locking ribs 74 are provided on the
inner face of wall 62 of projection 52, which locking ribs are
engageable with locking ribs 76 on the inner face of recess 50 when
the half-parts are stacked for storage purposes in manner as shown
in FIG. 11.
Locking ribs 78 on the inner face of center wall 54 serve a similar
function when the half-parts are stacked for storage purposes.
When stacking the half-parts, the projection of one half-part is
received within the hollow projection of the next half-part, while
the recess of half-part is received within the recess of the next
half-part.
While the table top 12 has been shown in the drawings as being of
round or disc shape in plan, it will be understood that it may be
square or rectangular or any geometric shape desired.
