Description
The present invention relates to a modular recreational unit which
may be employed as a single unit or in combination with like units
to provide infinitely variable recreational areas.
Most recreational facilities today employ various assembled
recreational combinations such as jungle gyms, slides, mazes and
the like, with each recreational unit separately assembled from a
plurality of various members, common only to the particular unit
being assembled. Assembly is a rather complex procedure and little
or no variation in form or design can be effected by a user or
assembler since the various components must be integrated in a
preset manner to provide a workable or stable unit.
Especially with the advent of such newer forms of recreational
facilities such as so-called "pocket parks" and the desire for more
recreational areas within limited city areas, such as on designated
play streets and the like, the problems of assembly and disassembly
and predefined size factors found in the more commonly recognized
recreational structures is more marked. Play areas today are
oftentimes carved out of empty lots, oftentimes of irregular shape,
and there is little uniformity between different play areas.
Especially in areas where specified play facilities are only set
aside during certain periods of the year, the desire for a
relatively simple and rapid method of assembly and disassembly is
desirable.
In a like manner, recreational equipment employed today by
homeowners in yards is not readily suitable to make the best use of
the space or topography available.
According to the present invention, a single structure which is in
itself a recreational unit and which is adaptable for mating with
like structures is provided wherein infinitely variable
combinations and permutations of recreational facilities may be
provided adapted to the particular spatial requirements, aesthetic
desires or functional demands of a user.
The basic unit of the present invention is a hollow cuboctahedron,
that is, a regular solid geometric figure having as faces, six
equal squares and eight equal regular triangles. Each of the square
faces includes a regular centrally located opening
therethrough.
As a single unit, the cuboctahedron having the apertures described
provides a stable play unit in the nature of both a maze and a
jungle gym. In combination with like structures either directly
linked through securing means provided in the unit or through the
use of hollow elongated connecting members, various other play
units may be provided.
Although such novel feature or features believed to be
characteristic of the invention are pointed out in the claims, the
invention and the manner in which it may be carried out may be
further understood by reference to the description following and
the accompanying drawings.
FIG. 1 is a perspective view of a recreational unit of the present
invention.
FIG. 2 is a rear view of a square section of the recreational unit
of the present invention.
FIGS. 3a and 3b are from views of a square and triangular section
respectively of a recreational unit of the present invention.
FIGS. 4a and 4b are side and front elevations respectively of a
connecting member of the present invention.
FIG. 5 is a side elevation of another connecting member of the
present invention.
FIG. 6a and 6b are side and rear elevations respectively of a slide
member adaptable for use with the recreational units of the present
invention.
FIG. 7 is a top view of an alternate embodiment of a unit of the
present invention.
FIGS. 8-10 are perspective view of various combination forms of the
present invention.
Referring now to the figures in greater detail, where like
reference numbers denote like parts in the various figures.
FIG. 1 illustrates the basic hollow modular cuboctahedron 1 of the
present invention having six square faces 2 and eight regular
triangular faces 3. Each of the square faces 2 includes a regular
centrally located opening 4 therethrough, thus making the hollow of
the cuboctahedron 1 accessible from six sides.
As shown in FIG. 2, the opening 4 in square side 2 preferably
includes a rounded inner edge 5 which extends slightly inward
towards the hollow center of the cuboctahedron 1. A protecting
sheath 6 may be provided for the circumference of the rounded inner
edge 5. The sheath 6 serves both as a strengthener for the edge 5
and a protective guard since, as hereinafter more particularly
described, the edges 5 serve as rests for the feet, arms or legs of
a user.
With the openings 4 positioned on the square faces 2 a user may
employ any of a plurality of selected openings 4 in order to exit
the hollow of the cuboctahedron. Thus, a single cuboctahedron 1
constructed in accordance with the present invention provides a
combination maze and jungle gym which may be traversed in an
external to internal to external, or purely external manner, with
the edges 5 providing footholds and/or gripping surfaces.
While a single unit provides a novel recreational unit in and of
itself, like units may be combined in various combinations and
permutations and such combined units may be selectively linked to
fit the specific desires and/or requirements of a user.
As shown in FIGS. 3a and 3b, apertures 7 may be provided on both
the square faces 2 and triangular faces 3 of the cuboctahedron 1 so
as to allow linkage bolts or the like (not shown) between like
sides of a number of units. Each aperture 7 is spaced near the
corner of its respective face, an equal distance from the epicenter
as like apertures 7 on the same face.
In such manner, aligned square faces 2 (or aligned triangular faces
3) between two cuboctahedrons 1 positioned so that the periphery of
such like faces 2, 3 lie in parallel planes will place the
apertures 7 on such two cuboctahedrons 1 into registry.
While as hereinafter more particularly described, innumerable
recreational units may be constructed by direct linkage of like
faces of a plurality of cuboctahedrons, supplemental members, such
as shown in FIGS. 4a, 4b, 5 and 6 may be provided.
Referring to FIGS. 4a and 4b, the linkage member 8 includes a
hollow tubular portion 9 having a circumferential opening on both
ends thereof of like size to the openings 4 on the square faces 2.
Both ends of the tubular member 8 include a flange 10 of
substantially equal peripheral configuration to the square face 2.
Apertures 11 are provided near the corners of the flange 10 so as
to be in registry with the apertures 7 hereinbefore described with
respect to the square faces 2 of the cuboctahedron 1. Affixation of
the linkage member 8 between square faces 2 of two cuboctahedrons 1
thus provides a conduit for passage between such two cuboctahedrons
1.
As shown in FIG. 5, a tubular member 12 may be employed having a
single flange 13 with apertures 14 therethrough. Such tubular
member 12 affixed to a square face 2 provides an egress passage to
and from the hollow of the cuboctahedron 1 and as hereinafter
described, where the cuboctahedron 1 is oriented so that a square
face 2 is oriented at an angle to the horizontal, such tubular
member 12 may be employed as a slide.
In FIGS. 6a and 6b, an open slide member 15 is illustrated
including a square connecting flange 16 having a circular central
opening 17 therein of equal circumference to the openings 4 on the
square faces 2. Means to mate the flange 16 with the square faces 2
are provided such as by providing aligned apertures 18 on the
flange 16 in a like manner as hereinbefore described with respect
to the prior flanges 10, 13. A downsloping, somewhat arcuate slide
portion 19 extends from the flange 16. The slide portion 19 is
preferably semicircular in cross section with the curvature of the
slide portion 19 being equal to and an extension of an arc of the
opening 17 of the connecting flange 16. A vertical supplemental
support 20 may be provided along the underside of the lower section
of the slide portion 19 for greater support and stability with the
support 20 adapted to rest upon the supporting surface upon which
the recreational unit is placed.
As illustrated in FIG. 7, the cuboctahedron 1 may include a
textured (i.e., rough) outer surface on all faces 2, 3. The
texturing of the outer surface is desirable to prevent slippage by
children or others when climbing about the recreational units and
additionally serves to provide some frictional retention between
linked units.
FIGS. 8-10 are illustrative of various combinations of units of the
present invention. In FIG. 8, the cuboctahedrons 1 are all oriented
so the base units are oriented edgewise to the horizontal support
surface 21. In such configuration, it is desirable that a vertical
support surface such as a wall 22 be available at the recreational
site for supplemental anchorage, which may readily be obtained by
anchor bolts (not shown) between a side of the cuboctahedron and
the wall 22.
In FIG. 9 the base cuboctahedrons are oriented so as to lie flat
upon one of its triangular faces 3 with the cuboctahedrons 1
directly linked between square faces 2 to form a triangular-shaped
unit.
FIG. 10 illustrates a portion of a unit wherein the base
cuboctahedrons are resting upon a square face 2 and further
illustrate the linkage member 8 of FIGS. 4a and 4b and the slide
member 15 of FIGS. 6a and 6b.
As the three above illustrations clearly indicate, practical as
well as aesthetic considerations may readily be taken into account,
and a "personalized" recreational facility can be provided for a
user. Modifications and/or additions can be accomplished by
rearrangement of units and/or the addition or subtraction of units
within the recreational area.
The terms and expressions which are employed are used as terms of
description; it is recognized, though, that various modifications
are possible.
