KNOCKDOWN STRUCTURAL TOYS
Abstract
A modular structural toy constituted by comparatively few basic
elements with which may be combined a virtually limitless number of
cylindrical members, such as waste beverage cans, for the assembly
of all types of structures striking the imagination of a child or
an adult. A cubical block is fitted with annular resilient
retainers, preferably of flexible plastic material, on five faces
thereof, wherefrom may be branched selectively in one or more
desired directions, a plurality of the cylindrical members which
are integrated at the juxtaposed ends by annular connectors having
resilient lips which encompass the annular beads at the ends of the
cylindrical members. A cylindrical projection extends from at least
one face of the central block which is shaped with an annular bead
resembling that on a can so that the block may be coupled closely
adjacent to another block by one of the annular resilient retainers
on the latter, or by one end of an annular connector. In order to
compensate for differences in length of the cylindrical members or
cans which may be used in the setting up of a structural assembly,
annular adapters may be interspersed in the assembly, each of which
may be fitted on one end thereof with a resilient annular lip for
encompassing the circular bead at the end of a can while the
opposite end thereof is formed with an outwardly extending rib
conforming to the outline and dimension of a bead, whereby it may
receive the annular lip of another adapter or an annular connector.
The lengths of the adapters and/or connectors may be varied to
provide an additional capability of controlling the composite
length of the cylindrical structural members integrated by said
adapters or connectors.

Description
This invention relates to knockdown construction toys constituted
by comparatively few basic modular elements with which may be
combined a virtually limitless number of cylindrical members such
as metallic receptacles which are employed for the packaging of
beverages and other products and which normally are thrown away
after their use.
It is the object of the present invention to provide a knockdown
construction toy assembly of rugged and simple construction which
may be fabricated at low cost and which makes possible the
utilization of cylindrical members such as metal cans, which
normally are considered waste.
It is another object of the invention to give free play to the
imagination of children, as well as adults, in the design and
construction of all types of building structures, furniture units,
human and animal caricatures, etc. These may assume many forms as
well as uses, so that not only may the assembly be used for the
amusement and education of children, but also as a stimulating and
pleasurable pastime for adults.
The invention aims to advance the art of toy designs, while
simultaneously presenting a limited solution to the present
antipollution problem, by providing an improved modular structural
assembly making use of a large number of waste beverage cans. The
invention presents an improvement over the arrangements disclosed
in U.S. Pat. No. 3,422,564, Jan. 21, 1969.

the special construction of the annular connector; and
FIGS. 16, 17, 18 and 19 are diagrammatic perspective views of
several illustrative structural arrangements which may be assembled
in accordance with the invention.
In FIG. 1 is shown a perspective view of one of the modular cubical
blocks B in accordance with the invention, which preferably is
molded of rigid plastic material, and is provided on the six faces
thereof with annular projections for selective coupling thereto of
cylindrical structural members or other types of connector
elements.
In the preferred embodiment of the invention shown in FIGS. 1 to 3,
the opposite faces 1 and 2 of the cubical block B are provided with
resilient annular projections 11 and 12 extending, respectively,
from faces 1 and 2 which may be molded integrally with the surfaces
of the block. These projections are of plastic material such as
polyethylene, and have sufficient flexibility to permit the passage
of a bead at the end of a metallic cylindrical can so that the
latter is detachably connected to the surface of the block and is
retained in place by the flexible lip 11' and 12', respectively,
which embraces the lateral wall of the can and retains the bead of
the latter within a groove extending inwardly of the resilient
lip.
Similar annular projections are provided on another pair of faces 3
and 4 of the cube and, as shown in FIG. 3, the annular projections
13 and 14 extend outwardly from these faces and terminate in the
inwardly directed resilient lips 13' and 14', respectively, for
engaging the ends of beaded cylindrical members which may be
affixed thereto.
The last pair of faces 5 and 6 of the cube are constructed
differently than the pairs of faces 1,2 and 3,4 described above. In
the case of face 5 of the cube, the same is fitted with an annular
projection 15 similar to annular projections 11, 12, 13 and 14,
described above, and is provided with an inwardly directed
resilient lip 15' for embracing the end of a beaded can or other
connector. However, face 6 of the cube is provided with a
cylindrical projection 16 which is molded with an outwardly
directed rib 16' of a dimension and contour of the same order as
that of an annular bead at the end of the can so that this rib 16'
may be coupled with annular projections provided with flexible lips
of the type extending from the other faces of the cube or flexible
lips on different types of connectors which are described in
greater detail below.
Preferably, the plastic cylindrical projections 16, 16' may be of
the same rigidity as the body of the cubical block while the
annular projections on other faces of the block have flexible
characteristics.
Annular connectors of plastic material such as polyethylene may be
used to interconnect the cylindrical member together, and one
embodiment of such is illustrated in FIGS. 4 to 6. A central web or
diaphragm 20 serves to impart sufficient rigidity to the connector
while the annular flanges extending from both sides thereof imparts
resilience to the unit so that the inwardly directed lips 23 and
23' may flex sufficiently to embrace the lateral walls of the
cylindrical cans immediately adjacent to the terminal beads 8 which
are received in grooves 24, 24' adjacent to the central web 20.
A tab 25 extends outwardly from the periphery of the connector, and
serves not only to facilitate the manipulation of the connector
relative to the beads with which the same is engaged, but in
addition serves as a spacer in the setup of the construction toys,
as explained in greater detail below.
The structural element or connector shown in FIGS. 4 to 6 may have
a length of approximately one-half inch, but connectors of
different length may be provided and such a variant embodiment is
illustrated in FIG. 7 where the connector C' is of greater length
and is formed of two spaced webs 30 and 30', wherefrom project the
annular flanges 31,31' terminating in flexible lips 32,32' beyond
grooves 33,33', respectively, which receive the beaded ends of the
cylindrical cans.
Such connectors as shown in FIGS. 4 to 7 may be used alternatively
or in conjunction with structural elements in the form of adapters
as shown in FIGS. 8 to 10, the purpose of which is to effect
connections between the cubes and/or cylindrical members when
variations in length of the latter are encountered. The adapters A
may be formed of resilient plastic material of the type of
polyethylene and other such plastics, and are provided with a
transverse circular web 40 therein to impart strength thereto. An
annular flange 41 at one end of the adapter terminates in an
inwardly directed flexible lip 42, for the purpose of embracing the
lateral wall of a cylindrical member adjacent the bead thereof or
an annular rib of another adapter. The opposite end of the adapter
A is fitted with a cylindrical projection 43 which terminates in an
outwardly extending rib 44 of the same dimension and contour as the
annular bead on a cylindrical member so that this rib may be
embraced by the flexible lip of any connector C which may be
coupled therewith.
In FIG. 11 is shown one of the many countless ways in which the
cubical blocks may be combined with the cylindrical structural
members and the connectors and adapters in the construction of a
desired structural unit. Thus, two cubical members may be connected
detachably by coupling the annular projection 15 extending
downwardly from the upper cubical block B with the cylindrical
projection 16 extending from the upper face of the lower block B'.
A cylindrical can 10, of conventional length, is coupled detachably
to the annular projection 13 extending laterally from the upper
block, while a shorter can 10a is connected with the annular
projection 11 extending laterally from the lower block. If the
desired assembly requires an equalization between the cylindrical
structural members, an adapter A is affixed to the right end of the
structural member 10a leaving the annular rib 44 on the right
thereof free for the engagement of a connector C as shown in FIGS.
4 to 6. Thereafter, another cylindrical structural member 10b may
have the beaded end thereof coupled to the opposite end of the
connector C to equalize the length of structural member 10 with
that of the composite length of structural members 10a and 10b.
Connectors C may be affixed to the right ends of the structural
members extending from both the upper and lower blocks B and B' to
which may be connected additional cylindrical structural members in
any desired manner. Furthermore, as shown in FIG. 11, the flexible
annular projection 15 extending from the lower end of the cubical
block B' may have connected thereto any number of cylindrical
members 10 coupled with the connectors C in any desired
arrangement.
In FIG. 12 is shown in greater detail, and on an enlarged scale,
the interengagement of the cylindrical projection 16 with the
outwardly directed rib 16' on cubical block B' with the annular
projection 15 and the inwardly directed resilient lip 15', which
makes possible the close juxtaposition of a pair of cubical blocks
leaving free the remaining faces thereof for the detachable
connection of the cylindrical structural members in any desired
direction. The engagement between blocks B and B' also permits a
relative rotation between them around the axis common to
projections 15 and 16.
FIG. 13 shows the juxtaposition of an adapter A with a connector C,
as shown in elevation in FIG. 11. Thus, the resilient lip 42 of the
adapter A is snapped over the right end of cylindrical member 10a
so that the bead 8 of the latter is received within the groove 42'.
The opposite end of the adapter, with the annular flange 43 and the
rib 44 is coupled to the left end of the cylindrical member 10b by
the engagement of the resilient lip 23' over the flange 43 and rib
44, while the opposite flange 21 of the connector 21 engages the
lateral wall of the structural member 10b and the bead 8 at the end
of the latter by means of the annular resilient lip 23.
FIG. 14 is an enlarged view showing the operation of the simple
connector C for the purpose of coupling the juxtaposed ends of the
cylindrical member 10 with the beads 8 at said ends. The flexible
lips 23 and 23' encompass the ends of the lateral walls of the cans
beyond the beads 8 which are seated in the grooves 24,24'.
FIG. 15 illustrates graphically the function performed by the tabs
25 in addition to the facilitation of the manipulation of the
connectors C in the course of engagement and disengagement of them
with the ends of the cans. Thus, in some structural arrangements
when a cubical block is set upon a surface S with the cylindrical
projection 16 and the rib 16' at the free end thereof, the cubical
block and the cylindrical member 10 extending therefrom would have
a tendency to tilt by virtue of the higher level of the attachment
of the cylindrical member relative to the free end thereof. Thus,
the location of the tab 25 in the lowermost position, which is of
the same height as the degree of protrusion of the cylindrical
projection from the bottom surface of the cubical block, serves to
level the cylindrical member relative to the supporting surface S.
This results in more stable structures, particularly if the tabs 25
are oriented at all points where supports thereby are desired.
In FIGS. 16 to 19 are shown a few different structural arrangements
of the many which are possible, by the selective combination of the
modular cubical blocks with the cylindrical members which may be
coupled together selectively by the resilient lips on the cubical
blocks, connectors and adapters with the annular outwardly directed
ribs projecting from at least one face of the cubical blocks, as
well as the annular outwardly directed ribs on the adapters and the
annular beads on the ends of the cylindrical members. The annular
construction of the lips and ribs on the cubical blocks, connectors
and adapters, when used in conjunction with the beaded ends of the
cylindrical members adapted to be connected thereto, makes possible
relative rotary movement between the several parts when such is
desired.
Thus, FIG. 16 may be considered a simulation of a robot which,
incidentally, may be maintained in a level condition by the
disposition of the levelling tabs 25 at the bottom of the end
coupling elements, as shown on an enlarged scale in FIG. 15.
FIG. 17 illustrates a gabled roof construction simulating a church,
and FIGS. 18 and 19 are simulative of a chair and table
construction, respectively.
The possibilities of variation of the structural units are
limitless and depend solely upon the imagination and skill of the
children or adults using the assembly.
While the specific embodiments of the invention illustrated herein
make possible the most universal and diversified assemblies, the
objectives of the invention may be attained with modifications of
the modular cubical block. Thus, cubical blocks having less than
five annular projections extending from the faces thereof, or
cylindrical projections with outwardly directed ribs extending from
more than one face of the cube may be used.
While the invention has its maximum potential for utility and
economy by the use of spent beverage cans, it is possible to use
cylindrical members having beaded ends of metal or other material
if such are desired and available.
The resilient flexible lips on the cubical blocks may be fabricated
of any desired thermoplastic materials in addition to polyethylene
mentioned above as long as they exhibit similar properties of
resilience and flexibility, for example, vinyl plastics and the
like.
