Description
BACKGROUND
This invention relates to children's toys, more particularly to
children's playground toys, and still more specifically to a type
of child's playground toy which may be constructed by the child and
played with and upon.
An advantageous child's playground toy is one which is versatile
enough to allow a child full use of his imagination, which is easy
to fabricate, and which is easy to transport. The present invention
provides such a toy.
In summary, the preferred embodiment of the child's building toy of
the present invention includes basic building units in the form of
L shaped members or angularized U members each having at least two
ends with a male connector on one end and a female connector on the
other end. The connectors are arranged to quickly connect and
disconnect to allow a child to interfit the basic building units
and construct an interconnected arrangement of units of its own
design comprising any number to the maximum available.
The basic building units are of a hollow construction allowing the
passage of water, and at least some of the units have apertures
formed therein to allow water passing through the units to issue as
a spray from the apertures. In this manner, water under pressure
may be applied to the interconnected arrangement of basic building
units of a child's design and issue from the apertures as a spray
upon children climbing and otherwise playing with and upon the
interconnected arrangement of basic building units.
Since each arrangement is of the child's own design, the children's
building toy of the present invention is versatile and allows a
child the full use of his imagination. Since each basic building
unit may be quickly connected and disconnected from another, the
toy may be quickly broken down to its constituent basic building
units, stored or transported, and again provided to a group of
children for play.
It is thus an object of the present invention to provide a novel
child's toy.
It is a further object of the present invention to provide a novel
child's toy which is versatile and allows a child full use of his
imagination.
It is a further object of the present invention to provide a novel
child's toy which is easy to fabricate.
It is a further object of the present invention to provide a novel
child's toy which is easy to transport and store.
This and further objects and advantages of the present invention
will become clearer in the light of the following detailed
description of an illustrative embodiment of this invention
described in connection with the drawings.

DESCRIPTION
In FIG. 1, an example of the myriad arrangements possible with the
children's building toy of the present invention is generally
designated 10. Arrangement 10 includes a plurality of basic
building units 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, and 22.
Each basic building unit 11-22 is interconnected to another in a
manner best shown in FIGS. 2 and 3.
In FIGS. 2 and 3, a water tight, rapid connect/disconnect member 24
is shown including a male connector 26 and a female connector 28.
The form of connector 24 used in the preferred embodiment is
manufactured by Dover Corporation/OPW Division under the trademark
KAMLOK quick coupling. Of course many other quick
connect/disconnect connectors may be used by those skilled in the
art. As shown, the male connector 26 includes an annular
indentation 30 into which two lever cams 31 having arm portions 32
and cam portions 33 can pivot upon pins 34 journaled in female
connector 28. The pivoting of lever cams 32 is such that when the
lever portion 32 is parallel to the longitudinal dimension of
connector 24, the engagement of the cam portion 33 pivoted upon the
female connector 28, with the annular indentation 30, formed in the
male connector 26, securely engages and mates the connectors 26 and
28. A gasket 35 between connectors 26 and 28 aids in maintaining a
water tight seal for purposes hereinafter explained.
Although not necessary, quarter stops 36, 37, 38, and 39, best
shown in FIG. 3, are useful in preventing the rotation of the male
connector 26 with respect to the female connector 28 caused by the
rotation of the cam portion 32 of lever cam 31 within indentation
30. The rotation is limited by quarter stops 37-39 in that the cam
portion 33 of lever cam 31 connected to the female connector 28 is
rotationally stopped by quarter stops 37-39 formed integrally with
the male connector 26 and within the annular indentation 30.
A male connector, such as 26, is then secured to one end of each
basic building unit 11-22 by threads or other means, and a female
connector such as 28 is secured to the remaining end of each basic
building unit 11-22 by threads or other means. Thus, connectors 40,
41, 42, 43, 44, 45, 46, 47, 48, 49, and 50, which are similar if
not identical to connector 24, interconnect the basic building
units 11-22 of FIG. 1 along with connector 24.
As shown in the Figures, the basic building units of the child's
building toy of the present invention take the form of elongated
members of at least two ends, such as the L shaped unit 17 best
seen in FIG. 4 having ends 51 and 52. Each basic building unit
includes at least one bend formed therein such as the ninety degree
bend 53 in L shaped member 17. Further, each basic building unit
includes a male connector attached to one end thereof and a female
connector attached to the other end, such as the female connector
54 forming a part of connector 45 on one end of basic building unit
17 of FIG. 4 and male connector 55 attached to the other end of
basic building unit 17 of FIG. 4 and forming a part of connector
44.
Another form of basic building unit is the angularized U member
best seen in FIG. 6 and designated 58. Angularized U member 58
includes a first leg 60 shown as arranged in upstanding direction
and having a female connector 62 threaded or otherwise secured to
the uppermost end thereof. The lower end of leg 60 is integrally
connected to a horizontally arranged leg 64 which forms a
connection between leg 60 and a leg 66 further horizontally
arranged at right angles to leg 60 and leg 64 and having a male
connector 68 threaded or otherwise secured to the outermost end
thereof. As can be seen from FIG. 6, leg 66 can have various
angular orientations with respect to legs 60 and 64 other than the
right angled orientation shown in solid line, and the term
angularized U member is defined for the purposes of this
description to include all of these orientations.
An example of the first angularized U member orientation is as
shown in solid line in FIG. 6. This orientation is characterized by
two legs at right angles to one another, such as leg 60 and 66. A
second angularized U member orientation is characterized by two
substantially parallel legs arranged in the same direction, such as
leg 60 and leg 66a shown in phantom in FIG. 6. A third angularized
U member orientation is a variation of the second orientation and
is characterized by two substantially parallel legs arranged in the
opposite direction, such as leg 60 and leg 66c shown in phantom in
FIG. 6. A fourth possible orientation is a variation of the second
orientation and is characterized by two legs arranged at
substantially right angles, such as leg 60 and leg 66b shown in
phantom in FIG. 6.
Thus in FIG. 1, the first orientation is exemplified by basic
building units 11, 19, and 21; the second oreintation is
exemplified by basic building units 12, 20, and 22; the third
orientation is exemplified by basic building unit 14, and the
fourth orientation is exemplified by basic building unit 18. The
remaining basic building units 13, 15, and 16 are examples of the L
shaped basic building unit such as unit 17 shown in FIG. 4.
Each basic building unit 11-22 of FIG. 1 is formed of tubing which
may be integral and bent as shown or may be straight pieces
interconnected by elbows. Being tubing, each basic building unit
includes a hollow formed therein such as to pass water. At least
some of the basic building units further include apertures, such as
apertures 70 shown in FIG. 4 with respect to L shaped member 17.
The apertures 70 provides a fluid connection between the hollow
inside of the basic building unit and the exterior and allow water
under pressure to be applied to the interconnected arrangement of
basic building units, such as that shown in FIG. 1 and issue from
the apertures 70 as a spray upon children climbing and otherwise
playing with and upon the interconnected arrangement of basic
building units.
As shown in FIG. 1, basic building unit 11 includes a connection 72
to a source of water under pressure, not shown, for example a water
hydrant. Basic building unit 22 further includes a connection 50 to
a hose 74 or other means for providing an exit for the water after
it flows through all of the interconnected basic building units of
the child's design, an example of which is shown in FIG. 1.
OPERATION
In operating the child's building toy of the present invention, a
child is taught to rotate the lever portion 32 of lever cam 31 from
the position flat against or parallel to the longitudinal dimension
of female connector 28, as shown in FIG. 2, to the furthest angular
position to which lever cams 31 will rotate about pin 34, such as
the position shown with respect to female connector 56 of FIG. 4.
The child is next taught to insert a male connector, such as male
connector 55 in FIG. 4, into female connector 56 and rotate lever
cams 31 back to their original position flat against or parallel to
female connector 56, such as the final position shown in FIG.
5.
The child may select any angular orientation of male connector 55
with respect to female connector 56, and, if used, quarter stops
36-39 will maintain this angular orientation at least within
90.degree.. The child should also be taught that if the cam portion
33 of lever cam 31 appears to be difficult to rotate, the cam
portion 33 may be engaging a quarter stop and should be rotated a
slight amount further. Being quite thin, quarter stops 37-39 do not
seriously interfere with manipulation of the toy by the child.
Therefore, a child may select and choose basic building units to
interconnect and construct an interconnected arrangement of basic
building units of its own design comprising any number of basic
building units to the maximum number available.
After an arrangement is completed, connector 72 may be connected to
a source of water under pressure, such as a water hydrant, hose 74
may be connected to safely disperse the water once it has traversed
the arrangement of interconnected basic building units, and those
basic building units having apertures 70 will provide a spray upon
the children climbing and otherwise playing upon and with the
interconnected arrangement of basic building units shown.
It may now be appreciated that the child's building toy of the
present invention allows the child to use his imagination and
construct an arrangement of his own design and thereafter allows
the child to play with the arrangement of his own design and derive
further satisfaction therefrom.
Also, the basic building units of the present invention may be
quickly disassembled, stored or transported to another site, and
again quickly made available for the amusement of children.
Thus, since the invention disclosed herein may be embodied in other
specific forms without departing from the spirit or general
characteristics thereof, some of which forms have been indicated,
the embodiments described herein are to be considered in all
respects illustrative and not restrictive. The scope of the
invention is indicated by the appended claims, rather than by the
foregoing description, and all changes which come within the
meaning and range of the equivalency of the claims are intended to
be embraced therein.
