Description
This invention relates in general to construction toys. In
particular, this invention relates to construction toys for
creating three dimensional illuminated designs.
Construction toys suitable for encouraging and exercising the
latent and overt creative desires of children, are quite popular.
In addition to providing children with a source of amusement and
entertainment for long periods of time, construction toys are also
generally educational in nature.
The construction toy of the invention provides a light box and a
plurality of construction elements which may be assembled to form a
three-dimensional design. The design may be colorfully illuminated
by a light source in the box projecting through a rotatable member
having a number of differently colored transparent areas.
The primary object of this invention is to provide a construction
toy for creating three dimensional illuminated designs.
Another object of this invention is to provide a construction toy
wherein construction elements may be inserted into a perforated
opaque panel overlying a light source and assembled generally
vertically to form an illuminated three-dimensional design, and
wherein a multicolored light-transmitting member may be disposed
intermediate the light source and the panel.
Additional objects of this invention will become apparent to those
versed in the toy art upon an understanding of the following
detailed description of the apparatus of the invention taken in
conjunction with the accompanying drawings, in which a preferred
embodiment of the construction toy apparatus is shown, and
wherein:
FIG. 1 is a perspective view of the construction toy of the
invention, with portions thereof broken away for clarity;
FIG. 2 is an enlarged, elevational cross-sectional view of the
construction toy of the invention;
FIG. 3 is an enlarged perspective view of the color wheel for use
with the construction toy of the invention;
FIG. 4 is a fragmentary plan view of the perforated covering panel;
and
FIG. 5 is a perspective view of a representative construction
element of the invention; and
FIG. 6 is a perspective view of a coupling element of the
invention.
Turning now to FIGS. 1 and 2 of the drawings, the selected
embodiment of the invention comprises a light box 10 having a
generally concave housing 11 defining an enlarged top opening 14
lying in a horizontal plane. A light source 16, in the form of a
lamp, is provided in the housing and a perforated panel 18 is
disposed in covering relation to top opening 14.
The construction toy further comprises a plurality of construction
elements 20 adapted for insertion into perforations in panel 18 and
suitable for being coupled together in a horizontal design. Light
is projected to the element portions inserted into the panel and is
transmitted through the coupled elements to illuminate the
three-dimensional design. A transparent color wheel 22 may be
rotatably carried in the housing and disposed intermediate the
light source and the panel for causing light to be projected to the
design.
More particularly, housing 11 of the light box is generally square
shaped and is formed by four outwardly sloping walls 24, and a
bottom wall 26. The bottom wall is formed to provide a support leg
27 at each corner of the light box. The housing carries a
conventional lamp socket 28 on its bottom wall, and an electric
cord 30 is provided for energizing the lamp socket by connecting it
to a suitable source of current. Lamp 16 is received by socket 28
and is located generally centrally of the housing for providing a
generally uniform light source for light box 10.
Panel 18 is fabricated of a sheet of opaque material and is
suitably dimensioned to form a closure for top opening 14. The
underside of the panel is supported on horizontal ledges 29 formed
outwardly from the top edges of sidewalls 24, and the periphery of
the panel includes a depending fascia 30 which extends outwardly of
the housing to reduce the escapement of light. It is unnecessary to
secure the panel to the housing, although during normal usage of
the apparatus it is unnecessary to remove the panel therefrom
except for replacement of the lamp.
As best seen in FIG. 4 the opaque panel 18 is perforated with two
different groups of perforations or openings 32 and 34, which are
characterized by their shapes. The group of perforations referred
to by reference numeral 32 are quincunicially arranged and are
suitably shaped for receiving the ends of construction elements
20.
The second group of perforations, referred to by reference numeral
34, comprise diagonally oriented elongated cooling slots for
allowing escapement of heat from lamp 16. The openings formed by
the cooling slots also enhance the illumination of the assembled
three-dimensional design, as will be noted in greater detail
hereinafter.
Panel 18 may include an integrally formed, depending, centrally
located boss 40. The boss is cylindrically shaped and may comprise
a number of fingers 46 having outwardly formed peripheral
projections 48. The fingers are capable of flexing to allow a
slight collapse and resultant reduction of the diameter defined by
projections 48 to facilitate mounting the color wheel.
Referring now to FIG. 3, color wheel 22 which may be used with the
invention is formed of four identically shaped, differently colored
quadrants 50 which may be joined together to form a circular wheel.
The identicalness of the quadrant shapes facilitates manufacture
thereof and a greater or lesser number of elements 50 may be used
without departing from the invention. The quadrants may be
fabricated of any light transmitting colored material which may be
joined together and is capable of withstanding the heat from lamp
16. While to colors red, green, blue, and yellow are used in the
described embodiment, other color combinations may also be
employed.
Each quadrant 50 of the color wheel comprises a light transmitting
colored sheet portion 51 defining a number of ventilating apertures
52 and having a plain edge 54 and a tab carrying edge 56. Edge 56
includes alternating upper and lower tabs 57 and 58, respectively,
which cooperate with the plain edge 54 of an adjacent quadrant 50.
The quadrants may be cemented together with any suitable adhesive
to form the color wheel and the tabs assist in strengthening the
resultant joint. Alternatively, the color wheel may be manufactured
by a sophisticated molding process capable of molding the entire
wheel in one operation.
Each quadrant 50 includes an externally knurled circumferential rim
60 for assisting in manually rotating the wheel. The quadrants also
include arcuate members 64 formed at generally right angles to
sheet portion 51 so that when joined together, members 64 form a
cylindrically shaped bearing having a vertical axis. The wheel is
supported on the panel and guided for rotation relative thereto by
fingers 46 and projections 48, respectively, of boss 40,
cooperating with bearing 64. The wheel is assembled to the panel by
slightly collapsing the boss and passing bearing member 64
thereover.
Each wall 24 of housing 11 is relieved at the center of its upper
edge by a rectangularly shaped opening 70. Openings 70 allow the
color wheel, as assembled beneath the panel, to be placed in the
housing with arc segments of knurled rim 60 extending therethrough
for allowing access thereto.
While cooperation between cylindrical member 64 and the bearing
fingers 46 afford lateral stabilization of the color wheel,
additional stabilization is afforded by horizontal ledges 72 formed
at the lower edge of opening 70 which cooperate with the underside
of rim 60.
Finally, in accordance with the invention, a plurality of the
construction elements 20 are provided, as illustrated in FIGS. 1,
2, 5 and 6. While the construction elements may assume different
longitudinal shapes, they are preferably fabricated of light
transmitting, translucent material such as plastic, and generally
include rodlike building elements 80 and nonrigid tubular
connecting elements 82. While elements 80 and 82 employ circular
cross sections, other cross-sectional shapes may also be
utilized.
Rods 80 include end portions 83 having a diameter suitable for
being firmly received in any one of the panel perforations 32 and
for telescopic engagement with coupling elements 82. The depth to
which the rods may be inserted into the perforations is limited by
a circular flange 84 inwardly adjacent each end. The different
longitudinal shapes which the rods may assume include straight
sections, such as representatively shown in FIG. 5, generally right
angle sections 92 and curved sections 93 (FIGS. 1--2). Obviously
other shapes of rods may be utilized in the construction toy.
The rods are fabricated of light-transmitting material such as
plastic, which has a critical angle such that most of the
transmitted light which strikes the inner wall surfaces is
internally reflected through the rod. The internal reflections may
be enhanced by polishing the outer surfaces of the rods. Each of
the rods may include externally protruding rings 86 spaced along
its length. Rings 86 intercept a portion of the internally
reflected light at an angle greater than the critical angle of the
material and transmits the intercepted light to the ring exterior
surface. Thus, under low ambient light level conditions the rings
appear brightly illuminated. Couplings 82 which are fabricated of a
translucent material are only slightly illuminated. Since most of
the light is internally reflected through the rod, rod ends 100 are
brightly illuminated and function to illuminate any overlying
structure.
In addition to the longitudinal construction elements, other
decorative pieces such as discs 94, squares 96, and simulated solid
pieces 98, each defining perforations for receipt of ends 83, may
be provided.
Any of the rods 80 may be connected together by coupling members 82
which as noted above, are fabricated of a pliable material and have
an internal diameter suitable for comfortably receiving rod ends
82.
Upon assembly of a three-dimensional design, it may be illuminated
by source 16 or it may be illuminated in a colorful and attractive
manner by light from source 16 projecting through color wheel 22.
Rotation of the wheel produces a variegated effect in the created
design. In addition, while light from lamp 16 is projected through
openings 52 in the color wheel and when these openings are
sequentially aligned with the perforations of panel 18, the white
light impinges on various parts of the overlying three-dimensional
design in an extremely attractive manner.
What has been described is a construction toy suitable for creating
a three-dimensional design which may be illuminated by different
colored light to produce a variegated effect.
It is obvious that upon study of those skilled in the art, the
disclosed invention may be altered or modified without departing
from its inventive concept.
