Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to construction toys.
2. Description of the Prior Art
Construction elements that can be fitted together in a variety of
manners make educational and interesting toys. Generally,
construction elements designed for small children have been in the
form of blocks that can be stacked or otherwise joined.
Construction elements of other than block shapes can provide
novelty that makes them especially interesting. However, such
elements should be versatile to enable their joining in a variety
of different manners and configurations. The elements preferably
should be easily joinable to one another or to another type of
element such as a block.
Block type elements generally can be easily formed by injection
molding of plastic type materials. Economical shipment and storage
is facilitated if the blocks can be originally formed in a
substantially flat configuration and if they can be readily
assembled by a child to a block form. If the assembly of the
substantially flat device into a block form can be performed in an
entertaining manner, as by the different parts easily snapping
together into a sturdy block without unsightly overhanging
portions, then the entertainment value of the construction element
can be further enhanced.
OBJECTS AND SUMMARY OF THE INVENTION
An object of the present invention is to provide construction
elements which are of a novel, versatile and highly entertaining
form.
Another object is to provide a construction element that can be
molded in a substantially flat shape and assembled by a child in an
entertaining manner into a solid-appearing object.
In accordance with the invention, cup or cone-shaped and block-like
toy construction elements are provided which can be joined into
interesting shapes. The cup-shaped construction element has a
tapered body with a narrowed end and a wide end, each end having
recesses and projections for coupling to other construction
elements. The recesses at the wide end are formed by a pair of
concentric flanges that extend axially from the wide end to form a
groove that can receive projections. The cup-shaped elements can be
joined together by inserting a projection at either end into a
recess at either end of another element, or by stacking the cups in
the same manner as paper cups are stacked.
The block-shaped construction element is formed from a
substantially flat member divided by living hinge areas into six
face portions, the member being foldable at the hinges into a
block. In order to allow the edges of the face portions to lock
onto one another, each edge has an inwardly extending rib at one
region and a recess at another region. When a pair of face portions
is maintained perpendicular and with adjacent edges, and the rib of
each edge is engaged in the recess of the other edge, the edges
cannot readily separate and the block is locked in
configuration.
The novel features of the invention are set forth with
particularity in the appended claims. The invention will be best
understood from the following description when read in conjunction
with the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIG. 1 illustrates a cone-shaped or tapered cup-shaped toy
construction element 10 and a block-shaped toy construction element
12 made in accordance with the invention, showing one manner in
which they can be joined together. The cone-shaped element has a
hollow body 13 in the form of a truncated cone with a wide end 14
and narrow end 16. The wide end 14 has three projections 18, 20 and
22 and a recess 24 divided into three parts by the projections. The
narrow end 16, also shown in FIG. 2, has a pair of projections 26,
28 and a pair of recesses 30, 32. Each of the five projections and
all of the recesses are formed so that when a pair of identical
cone-shaped elements are to be coupled, any projection of one
construction element can be received and tightly held in any recess
of the other element. The block 12 is constructed with a pair of
recesses 34, 36 in each face for receiving the projections of a
cone-shaped element. The block recesses or apertures 34, 36 are
spaced apart by the same distance as the projections 26, 28, at the
narrow end of the cone-shaped element so that a strong coupling can
be made to a single cone element.
The cone-shaped element is designed for very versatile coupling.
The recess 24 at the wide end is formed by a pair of axially
extending flanges 38, 40 which are concentric with the axis 42 of
the cone-shaped body. Each of the projections 18, 20, 22 at the
wide end lie in the recess 24 formed by the two flanges 38, 40 and
they project axially therefrom. The two ring-like flanges 38, 40
provide a large region where projections can be received, to
facilitate joining of construction elements in a wide variety of
configurations. The two recesses 28, 30 at the narrow end of the
cone-shaped element are elongated, which allows a pair of
cone-shaped construction elements that are joined at their narrow
ends to pivot a limited angle, such as 30.degree. relative to one
another. The cone-shaped construction elements can be joined not
only by inserting a projection into a recess, but also by stacking,
wherein the narrow end of one element is inserted into the hollow
space 44 of the body 12 of another element, as illustrated in FIG.
13. In order to avoid binding during stacking, which could prevent
a child from easily pulling one element off of another, the
elements are provided with a step 46 near the wide end that limits
the distance that one element can be received in another. The step
46 also stabilizes one stacked element on the other so that a large
number of elements can be stacked without readily toppling
over.
FIG. 5 illustrates a flat member 50 that can be assembled into a
block-shaped construction element of the type shown in FIG. 6. The
substantially flat member 50 has five linear folding regions 52,
54, 56, 58 and 60 of reduced thickness that essentially divide the
flat member 50 into six face members or face portions. The six face
portions 62, 64, 66, 68, 70 and 72 can be moved into the position
shown in FIG. 6 to form the block. Each of the face portions has a
pair of apertures 34, 36 with an inwardly extending flange 74 about
each aperture to provide a greater area of contact with a
projection to hold it therein. Each of the flanges may be provided
with a break 76 to facilitate deflection to more tightly engage a
projection, although such a break is not necessary. The member 50
may be constructed of a material such as polypropylene which forms
a durable hinge at narrowed areas thereof, such a hinge generally
being referred to as a living hinge.
In order to hold the six face portions of the member 50 in a cube
configuration, the edges of the face portions are designed to
tightly coupled or lock to each other. Each of the free edges is
provided with an inwardly extending rib 80 and a recess 82 for
receiving the rib from another edge. FIG. 7 illustrates the manner
in which two edge portions A and B of face portions 72 and 64 are
locked together, edge portion A having a straight outer edge
boundary 73 within which all parts are contained and the edge
portion B having an outer edge boundary 65 within which all of its
parts are contained. The rib 80A lies even with the boundary 73 and
extends inwardly from the inner surface 72I of the face portion 72
by a distance approximately equal to the average thickness t of the
face portion 72. The other edge portion B has a recess 82B which is
designed to receive the rib 80A. The recess has a maximum depth 2t
equal to the length of the rib 80A as measured from the outer face
of the face portion 72. Thus, when the rib 80A is received in the
recess 82B, a neat corner is formed wherein the rib 80A is flush
with the outer surface of the face portion 64.
In order to prevent the face 64 from swinging out in the direction
of arrow 84, a step or flange 86B is provided which extends along
the inside of the recess 82B and which can be engaged by the rib
80A. The flange 86B has an outermost surface 87B which is
substantially even with the inner surface of the face portion 64.
If the rib 80A is thicker or thinner than the face portion
thickness t, then the surface 87B should lie slightly behind
(inward) or in front (outward) of the inner surface of face portion
64, respectively. In a similar manner, a rib 80B of the face
portion 64 is received in a recess 82A of the face member 72. When
the two ribs 80A and 80B are engaged in the recesses 82B and 82A,
respectively, the two face portions 72 and 64 cannot be readily
separated. Separation generally requires that the ribs 80A and 80B
bend slightly to pass over the steps 86B and 86A. While such
disengagement can be performed by pulling hard on the face
portions, the face portions tend to remain locked together. Thus,
once the construction element is assembled, it tends to remain in a
block shape.
The substantially flat member 50 which contains the six face
portions, can be injection molded in a flat configuration, and
shipped and stored in this configuration to conserve space. The
child or an adult can assemble the member into a block shape. Not
only is space conserved, but the clicking sounds produced during
assembly and the ease of folding from a flat to a block shape makes
the assembly an entertaining activity. The substantially flat
member 50 can be formed with face portions that are of unequal
length, to form an elongated instead of cube box-shaped
construction element. It is also possible to provide triangular
shaped face portions to form a pyramid, or other shaped portions to
form a variety of other solid appearing objects.
FIG. 10 illustrates a construction element 90 which utilizes a
rotatable device 92 to further its versatility. The member 90 is
similar to the construction element shown in FIG. 5, but two faces
thereof have large apertures 100 for receiving discs 94 and 96 of
the rotatable device. The two discs 94 and 96 are held together by
an axle 98 to which they are fixed. It may be noted that each disc
has an outer portion 99 of a diameter approximately equal to that
of the aperture 100 in a face portion, and a larger diameter
portion 102 that bears against the inner surface of a face portion
of the cube. The rotatable device 92 can be installed prior to
snapping the face portions of the cube together, and it thereafter
remains in place.
FIGS. 11-17 illustrate many ways in which cone-shaped construction
elements 10 can be coupled to one another or to block-like
construction elements 12. The cone-shaped elements can be coupled
to the block-shaped elements by reception of any of their
projections in the holes 34, 36 formed in each face portion of the
block-shaped elements. The cone-shaped elements can be coupled
together either by reception of a projection in a recess or by
stacking in the manner shown in FIG. 13. The fact that each
cone-shaped element has three projections 18, 20, 22 at one end
enables it to be removed, rotated 120.degree., and reinstalled, to
rotate the projections 26, 28 at the opposite end so they are
perpendicular to their original position. This permits construction
of a window of the type shown in FIG. 17.
Although particular embodiments of the invention have been
described and illustrated herein, it is recognized that
modifications and variations may readily occur to those skilled in
the art and, consequently, it is intended that the claims be
interpreted to cover such modifications and equivalents.
