Description
It is an object of the present invention to provide a construction
element which can be readily used for the assembly of toys, models
and the like alone or in combination with other similar
elements.
Another object of the invention is the provision of a construction
element of the type described which can be assembled to attach to a
rod or other structural member and which when so attached is
retained in a predetermined position.
Another object of the invention is the provision of a construction
element of the type described in which the element is formed of two
segments matable by a tube, the mating of the segments being an
important and valuable aspect of the assembly of toys, models and
the like.
A further object of the invention is the provision of a
construction element of the type described which is economically
manufactured and which can be joined with other like elements to
provide a wide variety of assemblies, thereby diminishing the cost
of the entire model, toy or other structure, and at the same time
permitting the building of an infinite variety of structures.
In accordance with the invention, there is provided a construction
element comprising a pair of matable segments, the element when the
segments thereof are joined forming an elongated end adapted to
receive and mount a tube, and an enlarged or bulbous end. The
elongated end is integral with the enlarged end. A flexible strap
interconnects the enlarged end portions of the segments to form a
loop, which enables the element to be connected to a structural
member.

Referring in detail to the drawings, and particularly to FIG. 1,
there is shown a construction element 10 made in accordance with
the present invention and comprising a pair of complementary
segments 12 and 14 joined together by a flexible strap 16. In the
form of the invention shown, the element 10 is preferably molded
from plastic with the strap 16 formed integrally with the segments
12 and 14. However, the segments 12 and 14 may be made of metal or
other suitable material and the strap may be made of wire, cable or
cord and joined to the segments in any suitable manner, as by
embedding or the like as shown in FIG. 13.
The segments 12 and 14 are of matched construction, each comprising
a hemispherical portion 18 and an elongated semi-cylindrical
portion 20 extending radially therefrom. The segments 12 and 14
also have matching flat surfaces 22. The strap 16 joins the
hemispherical portions 18 at the points thereof diametrically
opposed to the semi-cylindrical portions 20. The segments may be
fitted together in the manner shown in FIGS. 2 and 3, with their
flat surfaces 22 in abutment and cemented together to form the
completed construction element 10. In this assembled condition, the
matching hemispherical portions 18 form a spherical end 24 and the
matching semi-cylindrical portions 20 form an elongated cylindrical
end 26. The strap 16 assumes the form of a closed loop, the ends of
which are integral with the respective halves of the spherical end
24. The assembled cylindrical end 26 is sized to fit frictionally
within and retain an elongated tube 28.
FIGS. 4 and 5 show three construction elements 10 assembled
together to form a triangular plan figure. In achieving this
figure, the three construction elements 10 in their original split
form are placed one upon the other with their straps 16 crossing
(see FIG. 6). The segments of the elements are then cemented
together to form the three assembled construction elements 10. In
assembling the construction elements, the straps 16 are
interconnected in the form of loops. FIG. 7 shows four construction
elements 10 interconnected in the manner described above to form a
tetrahedron assembly.
It has been previously suggested that the segments 12 and 14 of the
element 10 may be cemented together. However, if the tube is made
to fit tightly, frictionally over the cylindrical end 26 of the
assembled construction element 10, the tube 28 will itself hold the
assembled element together, without the necessity for cementing.
This is advantageous in that the tubes 28 can be removed when
desired, and the construction elements 10 can be separated for
reuse. A function of the enlarged end 24 is to serve as a stop for
the insertion of tube 28.
FIG. 8 shows one form which the elongated portion of construction
element 10 may take if the tubes 28 alone are to be used to hold
together the assembled construction elements. The segments 30 and
32 of the cylindrical elongated end are formed with confronting
wedge-shaped faces 34 and 36 which interfit when the segments are
brought together and ensheathed by a tube 28. The wedge-shaped
surfaces 34 and 26 prevent lateral relative movement of the
interfitting segments 30 and 32.
FIG. 9 shows another form which the cylindrical elongated end of
the construction element 10 may take. In this view, the segments 38
and 40 are formed with serrated confronting faces 42 and 44, which
intermesh to prevent longitudinal relative movement of the segments
38 and 40.
FIG. 10 shows segments 46 and 48, the confronting surfaces of which
are respectively formed with pins 50 and bores 52 which receive the
pins 50 to prevent both lateral and longitudinal movement of the
segments 46 and 48 when the latter are assembled.
The connecting straps 16 may be made of rubber or other elastomeric
or stretchable material, or may be in in the form of a spring. When
the straps 16 are made stretchable as well as flexible, they will
apply tension to any member about which they are placed, thereby
tending to hold the construction element stationary with respect to
such member.
The construction elements 10 may also be utilized in the building
of architectural models, toy structures or the like, and for this
purpose provide an extremely rapid, convenient and easy method of
joining the structural elements thereof. To this end an, assembly
kit featuring such construction elements may include, as shown in
FIG. 11, an elongated structural member such as a rod 54. The user
can then engage a construction element 10 to the rod 54 by
splitting the element 10, passing the segments 20 thereof about the
rod 54 so that the strap 16 forms a loop about the rod, then
bringing the segments face-to-face and slipping a tube 28 over the
segments to assemble the element. The strap 16 may be sized to
snugly engage the rod whereby the element will remain stationary
with respect to the rod. Even more desirably, the strap 16 may be,
as mentioned, elastomeric so that exact sizing of the strap is not
required and so that any element 10 can engage rods of varying
diameters. As further shown in FIG. 11, once one element 10 is
attached to a rod 54, another element 10A can be added to that
element, with the elongated ends 26 thereof being connected by a
tube 28. The element 10A can be formed into an assembly of such
elements as illustrated in FIGS. 4 and 7, and such process of
building element on element may continue almost endlessly. The
surface of rod 52 may be smooth, or optionally may be formed with
circumferential grooves or ridges, indicated at 55 in FIG. 11,
sized to receive the straps 16. The grooves 55 serve to mount the
construction elements 10 in predetermined locations along the rod
and also prevent lateral sliding movement of the elements on the
rod. It will be appreciated that the rod 52 may be straight,
curvilinear, closed into a loop, or of any other shape.
FIG. 12 shows the engagement of four construction elements to a
ring 56, with the elements being spaced arbitrarily equally about
the ring and another element 10B added on, in the process of
expansion of the structure. It will be appreciated that if the
straps 16 of the elements 10 mounted on the ring 56 are made
sufficiently long so that they extend loosely about the ring, the
elements 10 can be made to rotate about the ring in the manner of a
hinge. In this manner, the user can employ the construction
elements 10 to construct instant hinges upon linear or curvilinear
structural members.
The elongated portions of the elements need not be cylindrical but
may have square or other cross sections, as long as they correspond
to the cross-sections of the tube to be received thereon.
Illustrative of this variation is FIG. 14 wherein another
embodiment 10' of the construction element is shown. Therein, the
elongated end 58 of the construction element is square in cross
section, with each segment making up one half of the elongated end.
A tube 60 of square cross section fits over the elongated end. The
tube may be preformed to this shape or may be of flexible material
and given this shape as it is forced over the cylindrical end.
Further, the cylindrical end 26 may be made hollow in tubular form
and the tubes 28 may be made solid to fit within these tubular
cylindrical portions.
The enlarged ends of the construction elements need not be made
spherical. These portions may be made of various other shapes, and
even faceted as long as they have a relatively enlarged
configuration, larger in cross sectional dimensions than the
elongated end to form a "head" for the elongated end. Illustrative
of this variation is FIG. 15 wherein another embodiment 10" of the
construction element is shown. Therein the enlarged end 62 has a
bulbous configuration in the form of a hemisphere having its planar
face 64 situated away from the strap, and with cylindrical end
extending from said face.
There is thus provided a construction element which may be utilized
to make a practically limitless number of assembled forms and which
has particular value in the formation of models, toys and the
like.
