Description
This invention relates primarily to new and useful improvements in
play and exercise apparatus for children and in particular to a
module or block system comprising interconnected units adapted to
be placed in a variety of positions and combinations suitable for
playground use.
Children, even from the very young age of 5 or 6 months, have
strong desires to climb, crawl, slide and jump and perform other
exercises capable of developing their muscles and joints.
Psychologists further have found that many children desire to crawl
into and play within confined spaces. The children gradually
progress to higher levels of climbing ability and as the advance in
age, become more adventuresome and are willing to slide down and
jump from higher and steeper surfaces. It has been found that such
play serves to develop the muscular ability and also to develop
coordination between the various parts of the body and additionally
to provide long hours of recreation.
With conventional playground equipment, children frequently tire of
the various combinations of tricks and stunts that can be performed
on a given piece of equipment. Unless a playground is exceptionally
well equipped, the child frequently loses interest in such
exercise.
Accordingly, it is an object of the present invention to provide
play and exercise equipment for children which can be moved and
modified into various configurations.
Another object is to satisfy a child's basic desire to enter and
leave confined spaces and to jump, slide, and perform other feats
in order to develop the muscles.
A further object of the invention is to provide module playground
equipment comprising a plurality of interconnected play structures
that may be arranged into a small compact unit which may be stored
in a relatively small area.
A yet further object of the present invention is to provide a
plurality of hollow modular play blocks having egress openings
therein which can be combined with other similar units to provide
an endless passageway for crawling and exploration by children.
It is another object of the invention to provide play and exercise
equipment adaptable for use either indoors or outdoors which
includes a plurality of units that can be used with respect to each
other to provide a fairly low level arrangement or a higher
elevated configuration for use by children of various ages and
sizes.
A further object of the present invention is to provide a modular
playground system including a plurality of individual modules
adapted in one position of use to form generally rectangular or
cubic units, but which may be rearranged to form various concave
and convex surfaces for sliding purposes.
Another object of this invention is to provide a playground block
system wherein each individual block has color-coded indicia
thereon to indicate to the user various modes of positioning of the
blocks with respect to each other to form play units.
Another object of the present invention is to provide a playground
block system which is of sturdy construction, has a relatively
small number of parts, is economical to manufacture and use, and is
safe in use and relatively compact for storage.
For still further objects and for a better understanding of the
invention, reference may be had to the following detailed
description taken in conjunction with the following drawings which
illustrate the best mode now contemplated in carrying out the
invention and in which:
FIG. 1 is a perspective view of the playground block system in its
basic unextended form;
FIG. 2 is a perspective view of the system showing a portion
thereof swung into the extended position as indicated by the solid
arrow in FIG. 1;
FIG. 3 is a perspective view showing further manipulation of the
elements in the manner shown by the three arrows in FIG. 2;
FIG. 4 is a perspective showing further progression of the units
pivoted in the manner designated by the solid arrows in FIG. 2;
FIG. 5 is yet a further perspective showing additional progressions
of movement following the arrows of FIG. 4;
FIG. 6 yet is another perspective showing continuation of movement
of the modular sections following the movement of the arrows in
FIG. 5;
FIG. 7 is an enlarged fragmentary perspective of a preferred form
of hinge construction;
FIG. 8 is an enlarged fragmentary perspective showing a modified
form of hinge arrangement;
FIG. 9 is a side elevation taken from the front of FIG. 2 and
showing colored indicia portions for guidance;
FIG. 10 is a fragmentary perspective showing the use of the colored
indicia for assembly; and
FIG. 11 is a fragmentary side elevation also showing the use of the
color indicia for assembly.
Reference is now made specifically to the drawings wherein like
reference numerals designate similar parts throughout the several
views and wherein a typical installation of the assembly of this
invention is shown in FIG. 1.
The playground assembly consists of a plurality of individual block
modules of the various shapes designated 11, 12, 13, 14, 15, 16, 17
and 18. As can be seen in FIG. 1, the individual modules are
pivotally connected together in such a manner that the individual
modules can be arranged into a very compact cubic configuration
forming in essence a large block. By way of example, modules 11 and
12 are of similar external configuration and may be nearly cubical
in shape. It has been found that a particularly satisfactory size
for most purposes is 30 inches wide, 30 inches high, and 30 inches
in depth. Similar blocks 13 and 18 are also provided, all
preferably of the same general external size.
Each block is preferably hollow in the interior and provided with
at least one egress opening as shown at 23 in FIG. 3. By providing
two or more openings in each block of convenient size, through
passageways are thereby provided to adjacent modules to enable the
child to climb in and out of connecting units. It has been found
that a passageway having a minimum width of 13 inches is
preferable, and with a height of 21 inches or 24 inches. In the
preferred form of the invention shown in the drawing, openings 23
are provided with rounded corners to prevent snagging of the
clothing and other injury.
Block modules 14 and 15 are in the form of right triangles in
vertical cross section as best seen in FIGS. 2 and 11. These
modules are adapted to be swung about a hinge so that the
hypotenuse of each triangle will overlie the other in the closed
storage position providing in effect a rectangular solid
construction seen in FIGS. 1 and 2. It should be noted from FIGS. 3
and 11 that the blocks 14 and 15 are hinged along one edge so that
block 15 may be swung upwardly to assume the position shown in FIG.
3 whereby the hypotenuse faces provide a continuous slanting
surface and serve as a sliding board or ramp. See FIG. 3.
Another variety of sliding or climbing surface is provided by the
block modules 16 and 17. When these modules are swung to the closed
position shown in FIG. 2, the same provide an upright rectangular
solid. However, when the upper module 16 is pivoted on the hinge H
in the manner shown in FIGS. 2 and 3, a concave-convex surface is
provided which can be used either for sliding or climbing. In the
module 17, an opening is provided having a curved edge for the sake
of variety.
Each of the block modules 11--18 is hingedly connected to one
adjacent module by means of a hinge construction which may take
several forms. In the preferred embodiment shown in FIGS. 1--6, the
hinge is in the form of a conventional recessed piano hinge shown
in detail in FIG. 7. Here the adjacent block modules 16 and 17 each
have connected thereto one leaf of the hinge arrangement 19 and 20.
A hinge pin 21 passes through the interleaved hinge sections in a
manner well known in the art. It will be understood that the hinge
surface is recessed into the face of the panel so as to provide a
flush outer surface which is adaptable for sliding and climbing
without snagging on clothing and causing injury.
An alternative form of hinge 22 is shown at FIG. 8 and is known in
the art as an integral plastic hinge. This particular hinge is a
one piece plastic strip which may be either extruded or otherwise
formed and is flexible and strong and will not crack or break even
after thousands of pivotal movements. Once again, the panel
portions of the modules 16 and 17 are cut out or recessed and the
hinge is applied either by conventional adhesives or the same may
be laminated into place so as to provide an integral
appearance.
Each of the block portions as aforenoted is hollow and may be cast
or molded of any conventional yet sturdy material. It has been
found that fiberglass is an ideal material for this purpose since
the same is readily available, and may be molded and finished into
various shapes with ease and utilizing existing equipment. Of
course, if desired, the modules can be formed of sheet metal or
other substitutes. It is important in most installations that while
the modules be strong, they be light enough to be readily moved
into different configurations by a small child.
In order that a young child may readily move the various block
modules into preselected positions of use, the sides of the modules
may be painted with a color indicia instructional aid as more
clearly shown in FIGS. 9--11. FIG. 9 shows the module arrangement
of FIG. 2 with various color coded indicia applied thereto that
serves both a decorative function and also provides continuous
colored portions on adjacent panels which when placed in
juxtaposition create a continuous pattern. Movement of any one of
the modules out of the preselected position will be readily
apparent as the design will not be continuous and the user will
then know that one of the preselected arrangements is not in exact
alignment.
Referring to FIG. 10, block modules 24, 25, 26 and 27 are depicted.
Each side of the block modules is provided with a colored indicia
as indicated for example at 28 and 30 on module 25 and at 29 and 31
on module 26. When the modules 25 and 26 are pivoted with respect
to each other, the colored portions 30 and 31 will abut and present
a continuous pattern and further the colored portion 28 will align
with the colored portion 29 on the module 26 to provide a
continuous line indicia showing that the blocks are in proper
relationship.
While I have described my invention with particular reference to
the drawings, it is to be understood that various modifications and
substitutions of equivalents will present themselves to one skilled
in the art bearing the above noted objects of invention in
mind.
