Description
[0001] This application claims the benefit of U.S. Provisional
Patent Application No. 60/453,252 filed on Mar. 7, 2003, and U.S.
Provisional Patent Application No. 60/442,610 filed on Jan. 24,
2003.
FIELD OF THE INVENTION
[0002] This invention relates to children's building kits, and more
specifically to a panel and connector set for children to
temporarily construct structures.
BACKGROUND OF THE INVENTION
[0003] The present invention provides a construction set for
children. Many children use construction sets to create temporary
structures. Such kits are helpful to challenge a child's
imagination, and additionally assist children in learning spatial,
physical and interactional relationships.
[0004] One style of prior construction kit, such as Legos.RTM. kits
or blocks, uses hand or smaller sized pieces. These pieces can be
used to create miniaturized assemblies which children can easily
view and carry; however, such kits do not provide a child a larger
sized assembly to manipulate, nor do they provide interactive
play.
[0005] An alternate style of prior kits involves bulky or oversized
pieces that are used to create larger assemblies. Although larger
structures can be created, in kits with larger pieces hard and/or
heavy materials with potentially sharp edges can be unsafe for
falling on or otherwise causing a danger to the child. Separately,
manipulating larger heavy and/or awkward pieces can sometimes be
difficult for smaller children.
[0006] A different style of panel kits are not intended for
assembly and dis-assembly by children, but are used to create
structures which are intended to be semi-permanent for storage or
space separation. Typically these kits require fasteners and tools
for assembly, include larger and heavier components and may require
instructions or training for assembly. These systems are not
suitable for small children to play with.
[0007] There is a need for a safe yet flexible children's
construction kit. The present invention addresses this need.
SUMMARY OF THE INVENTION
[0008] According to a preferred embodiment of the present
invention, a modular toy building kit is provided. The kit includes
a plurality of building panels, each having a circumference with
edges. A plurality of tabs are defined on each panel with one tab
defined along each edge. The kit further includes a plurality of
connectors, each connector having a length and having slots defined
along the length. Each slot is sized to slidably receive and
temporarily retain a tab of a building panel.
[0009] Another embodiment of the present provides a self-contained
toy panel and connector building set. The set includes a base
having a rectangular support surface with four corners. The set
includes at least four connectors, each having a height and four
longitudinal sides with a longitudinal slot in each longitudinal
side. Each of the connectors is positionable adjacent one of the
support surface corners. The set further includes at least four
panels, each panel having tabs, wherein each tab is sized to be
received and selectively retained in one of the connector slots.
The panels are engagable with the connectors to form walls to a
storage compartment mounted on and enclosing the support surface on
the base. The storage compartment is sized to store additional
panels and connectors.
[0010] In a further embodiment, the present invention provides a
connector and panel set with a plurality of panels, each panel
having edges with lengths, and a plurality of connectors, each
connector having sides forming a standard height. Each edge of each
panel is engagable to a side of any connector and the height of the
connectors differs from the length and the width of each panel
edge. Preferably, a stack of connectors forms a height with joints
between the connectors and a stack of panels forms a height with
joints between the panels, wherein the joints of the stack of
connectors are not aligned with the joints of the stack of
panels.
[0011] In a still further preferred embodiment, the present
invention provides a toy set, having a panel and connector kit; and
one or more activity boards. The activity board is selectively
mountable and removable to the panel and connector kit. Preferably
the activity board comprises a hanging member configured to
selectively mount the activity board to a panel of the panel and
connector kit. The activity board provides a mounting area for a
range of games, learning materials, and/or writing or drawing.
[0012] It is an object of the invention to provide an improved
panel and connector system for children.
[0013] It is a further object of certain preferred embodiments of
the present invention to provide a toy panel and connector system
which is easy and safe for small children to assemble and
disassemble.
[0014] Further objects, features and advantages of the present
invention shall become apparent from the detailed drawings and
descriptions provided herein.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0045] For the purposes of promoting an understanding of the
principles of the invention, reference will now be made to the
embodiments illustrated and specific language will be used to
describe the same. It will nevertheless be understood that no
limitation of the scope of the invention is thereby intended, such
alterations, modifications, and further applications of the
principles of the invention being contemplated as would normally
occur to one skilled in the art to which the invention relates.
[0046] According to some preferred embodiments, the present
invention provides an activity set for children, for example small
children such as three year olds. In certain embodiments, the
activity set is a kit that includes panels and connectors plus
additional pieces. Children may assembly the panels and connectors
in various configurations without tools, fasteners or training to
create temporary structures designed by their imagination. In
preferred embodiments the elements of the kit are lightweight and
sized to be easily manipulated by children yet sturdy for long-term
play. Preferably the kit is made from materials suitable for indoor
and outdoor use. The kit elements are preferably modular to be
substantially interchangeable and are designed to facilitate ease
of assembly and dis-assembly.
[0047] Illustrated in FIGS. 1 and 2 is one preferred embodiment of
the present invention included system or kit 10. Kit 10 generally
includes long panels 30, short panels 40 and connectors 50. As a
preferred feature, kit 10 can be configured to form a
self-containing storage compartment. In the embodiment illustrated,
four connectors 50 form corners 26 arranged on a generally
rectangular base 14. Two panels 30 form the sides 22 and two panels
40 form the ends 24 and interconnect with corners 26 to form an
interior storage compartment. A lid 20, similar to base 14, may be
placed across the top of the storage compartment. Wheels 16 are
optionally mounted to base 14 to facilitate the ability to move kit
10.
[0048] The interior of the storage compartment is arranged to
receive the pieces of kit 10. For example, FIG. 2 illustrates
horizontal stacking of long panels 30, short panels 40 and
connectors 50 on base 14 within the sides 22, ends 24 and corners
26. Alternately, the panels may be arranged in a vertical
stack.
[0049] The elements of kit 10 are preferably interchangeable and
connectable to form various configurations, such as walls, doors
and/or windows. Non-limiting examples of arrangements are
illustrated in FIGS. 3A-D. Preferably the edge portions of the long
panels 30, short panels 40, triangular panels 70, base 14 and lid
20 are removably and slidably interlockable with connectors 50 to
form structures. The panels and connectors can be arranged
vertically, horizontally and/or stacked as desired. Non-limiting
examples of potential configurations include a maze, a playhouse, a
cave, a climbing structure, a loft, an airplane, a train, a chair
and a table.
[0050] Views of a preferred embodiment of a long panel 30 are
illustrated in FIGS. 4A-C. Panel 30 is preferably formed in a
generally rectangular shape forming a length (l) and a width (w)
with curved corners, although other geometric shapes with generally
straight edges can be used, examples include triangles, trapezoids,
pentagons, hexagons, and octagons. As illustrated, panel 30
includes four edges 32. Extending from each edge is a web or
thinner portion 34. At the outer portion of each web 34 is a
connector or tab, such as a T-shaped tab 36. Each web and tab
extends generally along the length of an edge, terminating adjacent
the beginning of the arcuate corner curve. As a preferred feature,
each tab 36 includes a changed cross-section which is a beveled or
tapered portion 37 in both width and thickness adjacent one or
preferably both ends. As a separate preferred feature, panel 30
defines mounting openings 39. As an optional feature, panels may
have circular openings or handles 38 assisting for grasping the
panels, or portions formed or removed to form windows. Such windows
will typically be open, with a frame formed by the surrounding
panel.
[0051] Views of a preferred embodiment of a short panel 40 are
illustrated in FIGS. 5A-C. Panel 40 is preferably formed in the
rectangular shape of a square forming a length (l) and a width (w),
although other geometric shapes can be used. Panel 40 includes four
edges 42. Extending from each edge is a web or thinner portion 44.
At the outer portion of each web 44 is a connector or tab, such as
a T-shaped tab 46. As a preferred feature, each tab 46 includes a
changed cross-section which is a beveled or tapered portion 47
adjacent one or both ends. As a separate preferred feature, panel
40 defines mounting openings 49.
[0052] Views of a preferred embodiment of a triangular panel 70 are
illustrated in FIGS. 6A-C. Panel 70 includes three edges 72, two of
which form a base and height of equal length (w). Extending from
each edge is a web or thinner portion 74. At the outer portion of
each web 74 is a connector or tab, such as a T-shaped tab 76. As a
preferred feature, each tab 76 includes a changed cross-section
which is a beveled or tapered portion 77 adjacent one or both ends.
As a separate preferred feature, panel 70 defines mounting openings
or handles 79.
[0053] Views of a preferred embodiment of a connector 50 are
illustrated in FIGS. 7A-C. Connector 50 has two ends and four
longitudinal sides defining a height (h). Each longitudinal side
defines a longitudinal slot or groove 56 between corner edges 52.
Preferably slot 56 is configured to slidingly receive a tab 36, 46
or 76 of any kit panel 30, 40 or 70. In a preferred feature, corner
edges 52 include slight bevels or tapers 57 at one or both ends to
facilitate the introduction of tabs into slots 56. In a further
preferred feature, the corner edges 52 include feet 53 defined at
each end of connector 50. Feet 53 assist in stabilizing and
stacking each connector 50.
[0054] Illustrated in FIGS. 8A & B is one preferred embodiment
of an activity board 60 usable in certain embodiments of kit 10.
Activity board 60 is selectively mountable to panels of kit 10. As
illustrated, board 60 is formed in a generally rectangular shape
sized to fit approximately within the edges 32 of a long panel 30.
This is for illustration only and alternate sizes and geometric
shapes can be used as desired. Various children's activities such
as posters, chalkboards, marker boards, and/or educational
activities or games can be mounted on activity board 60. Preferably
extending from activity board 60 is an offset member or hanger 62.
Hanger 62 is configured to selectively mount activity board 60 to a
chosen panel.
[0055] In a preferred embodiment, hanger 62 includes a handle
portion 64. Handle portion 64 is illustrated as a spherical portion
or ball, but alternate shapes such as hooks, cross-members, springs
or clamps can be used. In one embodiment, hanger 62 is a
short-cylindrical member connected at a proximal end to board 60
and connected at a distal end to handle portion 64. Handle portion
64 can be connected to hanger 62 by a screw-on connection, welding,
rivets, integrally molded or similar well-known connection methods.
Preferably, hanger 62, including handle portion 64, is sized to fit
through openings in panels 30, 40 or 70. In a preferred embodiment,
activity board 60 includes two hangers 62 with handle portions
spaced at a sufficient distance to engage two opening in the same
or separate panels.
[0056] Illustrated in FIGS. 9A-D are views of an activity board 60
mounted to a panel, for example panel 30. When placing board 60 in
position, hanger 62 with handle 64 is guided through an opening 39
in a selected panel 30. Board 60 is then released slightly downward
to rest hanger 62 on the lower portion (as oriented) of opening 39
to prevent downward movement of board 60 relative to panel 30 (FIG.
9D). Further, preferably a portion of handle 64 extends slightly
beyond the inner edge of opening 39 when hanger 62 is resting on
the lower portion of the opening. The portion of handle 64 which
overlaps panel 30 prevents hanger 62 from unintentionally
withdrawing from opening 39. Preferably with two such hanger and
handle connections to panel 30, activity board 60 is prevented from
unintended separation.
[0057] As a preferred safety feature, jostling or accidental
movement of activity board 60 relative to panel 30 typically moves
hanger 62 around the periphery of the inner edge of opening 39.
Such movement around the periphery maintains the overlap of a
portion of handle 64 over the panel, minimizing the risk of
accidental separation. Activity board 60 is removed by lifting the
board and guiding handles 64 through the center of openings 39. It
will be understood that the hangers and activity board can be
mounted in both horizontal and vertical orientations to long or
short panels of kit 10 with appropriate sizing and
arrangements.
[0058] Views of a preferred embodiment of base 14 are shown in
FIGS. 10A-F. In one embodiment, base 14 is slightly thicker than a
standard panel, and the lower side (FIG. 10D) optionally includes
recesses 17 for castors or wheels 16. During shipment or storage,
wheels 16 can be stored in recesses 17 to conserve space, and are
removed and mounted to base 14 when desired.
[0059] Base 14 is preferably slightly larger than a standard panel
of kit 10 to provide a sturdy base when kit 10 is in a
self-containing storage arrangement. Extending from the edges of
base 14 around a support surface are side supports 18 and end
supports 19. Side supports 18 and end supports 19 include tabs
similar to the tabs on panels 30 or 40 which are slidably
connectable to connectors 50. Side supports 18 and end supports 19
further include wider webs or support portions 34' and 44'
extending between the edges of base 14 and the tabs. Preferably the
wider webs 34' and 44' are dimensioned so that the profile of tabs
34 or 44 on panels 30 or 40 is receivable between the base edges
and the support tabs. When kit 10 is in a stored configuration,
sides 22 and ends 24 rest upon side supports 18 and 19, preferably
on webs 34' and 44', to enclose the support surface.
[0060] In one embodiment, a slight protrusion or lobe 21 extends
from each corner of the base and supports at least one foot 53 of
each corner connector 26 to prevent the corner connector from
sliding below the level of the support surface. Preferably the
storage compartment volume over the support surface is sized to
contain and store panels and connectors. Lid 20 is preferably
similar to base 14. In a preferred feature (not shown), base 14 and
lid 20 include partial impressions to provide a similar look to
openings 38 in long panels 30.
[0061] In preferred features, the components of kit 10 are
lightweight materials without sharp edges or sharp corners. For
example, the kit can be made with hollow, blow-molded, polyethylene
panels and injection molded ABS connectors. Alternately, the panels
can be made from a transparent material, such as polycarbonate,
which may be clear or tinted.
[0062] In a preferred embodiment, the panels and connectors are
based on the largest practical size which a small child, such as a
three year old, can manipulate and assemble with two hands. As a
non-limiting example, in one embodiment short panels 40 have a
length and width of eighteen (18) inches, large panels have a
length of thirty-six (36) inches and a width of eighteen (18)
inches and connectors 50 have height of thirteen and a half (13
1/2) inches, and triangular panels 70 have a base and height of
eighteen (18) inches. In this embodiment, the panels are
approximately one and half (1 1/2) inches thick. Base 14 has a
length of forty-one (41) inches and a width of twenty-three (23)
inches. Typically in this sizing, the child will only have a
limited vertical reach, limiting the overall height of the
assembled structure. According to this example, the typical maximum
assembly height by a three-year old would be fifty-four inches.
[0063] In one aspect of kit 10, preferably the connector height
differs from the length and width measurements of the panels. This
ensures that one connector will be shorter (or longer) than any
panel while a stack of connectors will span any joints between
panel stacks within a typical child's reach without the connector
joints and panel joints being aligned or having equal heights. For
example, if the panel dimensions are in eighteen inch multiples and
the connectors are thirteen and half inches in height, two short
panels can be stacked, forming a height of thirty-six inches and a
joint at eighteen inches. A stack of three connectors will have a
height of forty and a half inches with joints at thirteen and half
inches and twenty-seven inches. A long panel would have the same
geometry without one joint. Examples of this concept are
illustrated in FIGS. 3A-C.
[0064] The system of the present invention is usable by a small
child without using tools or fasteners or the need for training.
Typically for shipment or storage, kit 10 is placed in a
self-containing arrangement with or without the wheels attached.
When used by a child, the child can choose components of the system
to assemble a structure as desired. Access to components can be
facilitated by removing one side (FIG. 2). When assembling
components, the edge portions or tabs of a panel are slidably
engaged with a slot on a connector (FIGS. 3A-B). The beveled or
tapered end portions on the panel tabs and the connector slot edges
facilitate the introduction of the tab into the slot and ease the
sliding engagement. This creates a temporary interlocking
engagement where the panel and connector cannot be disengaged
except by sliding. Preferably the interlocking engagement includes
sufficient "wiggle" room in the connection that the sliding
engagement and dis-engagement is easily done without binding and
allows the angle of the panel to the connector to be slightly
adjusted as desired.
[0065] For continued assembly, multiple connectors and combinations
of short and long panels may be combined in vertical and horizontal
arrangements to create temporary structures, examples are shown in
FIGS. 3C-D. When play activity with the kit is complete, the pieces
can be efficiently dis-assembled and returned to a storage
configuration.
