Description
This invention relates to a construction game, and particularly to
a set of toy construction elements from which various structures
may be assembled quickly and without the use of tools.
Sets of variously shaped wooden or plastic bricks held together by
gravity only, and sets of structural toy elements assembled by
connectors or by interengaging parts are staple articles of
commerce. The range of structures that can be assembled from bricks
is limited, and the construction games relying on interengaged
elements or connectors require more skill, patience, and sometimes
even force than a child of nursery age or younger can muster.
The object of the invention is the provision of a set of toy
construction elements from which even a very young child can
assemble a variety of relatively large structures, such as toy
houses or play houses, in a short time.
With this object and others in view, the invention, in its more
specific aspects, provides a set of toy construction elements
including a plurality of flat plates and a plurality of disc-shaped
connectors. Each plate has a plurality of angularly offset,
elongated edges and two spaced guide faces which transversely
intersect each edge and therebetween bound a web section of the
plate.
Each connector has an axis and a circumferential portion extending
about the axis. Slots in the circumferential portion in respective,
angularly offset, axial planes separate radially elongated,
resiliently deformable tongue parts of the circumferential disc
portion. Each slot is dimensioned to receive therein one of the
afore-mentioned web sections under the resilient pressure of the
adjacent tongue parts while the plate which includes the received
web section extends substantially in the axial plane of the slot,
and at least one of the guide faces engages an associated tongue
part.
Other features, additional objects, and many of the attendant
advantages of this invention will readily become apparent as the
same becomes better understood by reference to the following
detailed description of preferred embodiments when considered in
connection with the drawing wherein:
FIGS. 1a, 1b, 1c, 1d, and le show respective plate members of a toy
construction set of the invention in perspective view;
FIG. 2 shows a web section and associated features common to the
several plate members of FIGS. 1a to le in a fragmentary,
perspective view on a greatly enlarged scale;
FIG. 3 is a perspective view of a connector;
FIG. 4 shows a fragment of the connector of FIG. 3 on a much larger
scale; and
FIG. 5 is a perspective view of a play house or doll house
assembled from plate members and connectors of the invention.
The several flat plates shown in FIGS. 1a to 1e are merely
illustrative of the variety of sizes and shapes that are preferably
included in a set of construction elements of the invention, but
other shapes will readily suggest themselves.
The plate 1a is square and its thickness is but a small fraction of
the length of its four narrow edges. The center of each edge is
reduced in thickness to a thin web section 11, and bores 15 extend
through the plate 1a at the geometrical center of its two parallel,
major surfaces and near the four corners of the plate.
The thickness of the plates 1b, 1c, 1d, 1e in the respective
equally numbered Figures is the same as that of the plate 1a, and
the web sections 11 have the same dimensions and configuration as
will presently be described with reference to FIG. 2.
The plate 1b is rectangular, as wide as the plate 1a and twice as
long. It has two spaced web sections 11 in the two long edges and
one in each of the short edges. The plate 1c is also rectangular,
but shorter than the plate 1b, and provided with only one web
section 11 in each of its four straight edges. The plate 1d is
square, twice the length and width of the plate 1a, and provided
with two spaced, reduced web sections 11 in each edge. The plate 1e
has the shape of a right triangle whose hypothenuse edge has the
same length as the longer edge of the plate 1b or one side of the
plate 1d, and is provided with two web sections whose spacing is
equal to that of the web sections in the longer edge of the plate
1b or in any edge of the plate 1d. The cathete edges of the plate
1e each have one centered web section 11.
Details of a web section 11 and of associated identical features of
an edge 1 in any one of the illustrated plates are shown on a
larger scale in FIG. 2. The web section 11, two elongated guide
faces 12 of the illustrated plate, and an abutment face 13 of the
plate bound a recess 16 in one of the major surfaces of the plate,
and an identical recess 17, only partly visible in FIG. 2, is
formed in the other major surface. The recesses 16, 17 are aligned
in the direction of plate thickness and are mirror images of each
other relative to a plane of symmetry parallel to and equidistant
from the two major surfaces in which the web section 11 is
located.
The faces 12, 13 are each elongated and connect the associated
major surface with the web section 11. The guide faces 12 intersect
the edge 1 at right angles while the face 13 is spacedly parallel
to the edge 1. The faces 12 are spaced from each other and bound
the web section 11 in the direction of edge elongation. The
recesses 16, 17 extending inward from the edge 1 and from the
respective major surfaces, and the latter are bounded by the
several elongated edges 1 of which only one is shown in FIG. 2 The
face of web section 11 which forms the bottom of the recess 16 has
a shallow, cylindrically arcuate groove 14 parallel to and spacedly
adjacent the abutment face 13, and a corresponding groove in the
web section 11 open toward the recess 17 is not visible in the
drawing.
The plate members of the toy construction set may be assembled by
means of identical connectors 2 of which one is shown in FIG. 3,
and partly in greater detail in FIG. 4. Each connector 2 is a
circular, cylindrical disc whose axial dimension is approximately
one third of its diameter. Eight slots 21, in respective axial
planes offset 45.degree. about the connector axis, divide the
circumferential portion of the connector 2 into eight radially
elongated tongues 22.
The preferred material of all toy construction elements of the
invention is a somewhat resilient synthetic resin composition such
as nylon which is readily injection molded in the illustrated
shapes. The slots 21 have parallel, approximately radial walls, and
the tongues 22, thererfore, taper in a radially inward direction
and are resiliently deformable, particularly by bending their
radially innermost roots.
Each slot 21 is dimensioned to receive therein one of the web
sections 11 under the resilient pressure of the two tongues 22
which bound the slot, and which hold the plate member associated
with the received web section substantially in the axial plane of
the receiving slot, as will presently be described with reference
to FIG. 5.
The axial height of the connector 2 is equal to or only slightly
smaller than the spacing of two guide faces 12 so that at least one
of the two guide faces touches a radial face of one or both tongues
22 separated by the slot 21 in which the associated web section 11
is received.
An axial rib 23 of cylindrically arcuate contour projects from each
tongue 22 into each of the two adjacent recesses 21. The rib is
spacedly adjacent the outer circumferential face of the connector 2
for engagement with a corresponding groove 14 in an inserted web
section 11 when the outer circumferential face of the connector 2
engages the abutment face 13. The engaged ribs 23 and grooves 14 in
corresponding engagement faces of the connector and the associated
web section radially secure the connector on the plate, and the
same result may be achieved in an obvious manner, not shown, by
providing grooves in the radial slot faces of the connector, and
ribs on the exposed major faces of the web section 11. A single rib
23 in each slot may be sufficient with a plastic connector material
stiffer than that presently preferred for molding the connectors
2.
A bore 24 passes axially through the center of each connector 2 and
is of the same diameter as the several bores 15 which pass through
each of the plate members 1a -- le in patterns chosen to permit the
use of several cylindrical plastic rods or wooden dowel pins (not
shown) for simultaneously connecting parallel plates as structural
reinforcement or as shafts for rotating elements, the connectors 2,
for example, providing wheels for toy vehicles assembled from a set
of structural elements of the invention.
The manner in which several plates of the set may be assembled by
means of the connectors 2 is illustrated, by way of example, in
FIG. 5, but the number of structures capable of being built by
means of the set is limited only by the number of elements in a set
and a child's imagination.
The structure shown in FIG. 5 is a play house or doll house open in
a direction away from the viewer. Its pitched roof consists of two
identical plates 1b linked at an angle of 90.degree. by a connector
2 engaging web sections in the centers of short edges of the two
plates. Two connectors 2 link the roof plates to respective cathete
edges of a gable plate 1e' which has the shape of an isoceles,
right triangle. A square plate 1a depends vertically at an angle of
135.degree. from the lower, horizontal edge of each roof plate 1b
to form a side wall of the house, and two juxtaposed plates 1c
depending from the hypothenuse edge of the plate 1e' provide the
front wall of the house. Two additional plates 1c provide the
floor. Connectors are arranged between the roof and gable plates
1b, 1e' and the dependent wall plates 1a, 1c, and between the
latter and the floor plates 1c, but none are needed, though capable
of being provided, between the wall plates 1a, 1c, nor between the
two floor plates 1c. The entire toy house thus consists of 9 plates
and 13 connectors of which two are obscured in the view of FIG. 5,
and is quickly assembled even by a very young child without taxing
its attention span.
Straight-edged plates are generally handled with greater ease by a
beginner, but plates having arcuate edges may be added to the set
when the child becomes more familiar with the game. Connectors
having fewer than eight slots and angularly arranged otherwise than
as specifically shown also have applications in connection with the
plate elements, but the illustrated connectors have been found to
be most versatile and adequately to cover the angular relationships
between connected plates that are readily understood by the user
for whom the set is primarily intended.
The recesses 16, 17 and associated guide faces may be provided in
one major face of each plate only at some loss in strength of the
assembled structures. It is also possible to avoid recesses in the
plate edges and to make the web sections of the same thickness as
the remainder of the associated edge, and to have them bounded by
guide faces on projecting integral ribs on one or both of the major
plate surfaces. The illustrated dimensional relationship of the web
sections to other parts of the set is preferred, however. One of
its advantages resides in the relatively small dimensions of the
connectors required for securely attaching the plates to each
other.
It should be understood, therefore, that the foregoing disclosure
relates only to preferred embodiments of the invention, and that it
is intended to cover all changes and modifications in the examples
of the invention herein chosen for the purpose of the disclosure
which do not constitute departures from the spirit and scope of the
invention set forth in the appended claims.
