Description
BACKGROUND OF THE INVENTION
The present invention relates to a toy-type device which is
designed and adapted for the entertainment and enjoyment of
children engaged in snow-ball throwing activities. More
particularly, the present invention is directed to a manually
operable mechanical device which can be used by children to form
snowballs.
The throwing of snowballs is a normal and healthly activity engaged
in by children and young adults of all ages. Individuals engaged in
snowball throwing activity generally utilize their hands in forming
the snowballs. In using bare hands to form snowballs, the coldness
transferred from the snow to the bare hands generally substantially
limits the ability to engage in snowball throwing for an extended
period of time. In situations where the hands are protected by
gloves or mittens, the gloves or mittens soon become wet due to the
transfer of heat from the hands through the gloves or mittens to
the snow. Accordingly, the gloves or mittens soon become wet and
the hands become very cold. This is particularly true when the snow
fall is of a wet type. The same problem is encountered even in snow
falls of the dry-type with the further complication that it is very
difficult to apply sufficient pressure between the hands to make a
snowball which will stick together.
SUMMARY OF THE INVENTION
An object of the present invention is to provide an easy to use
toy-like device which can be used by children and young adults of
all ages to make snowballs.
Another object of the present invention is to provide an easy to
use snowball forming device which can be conveniently grasped in
the hands of the user and which can be adapted to scoop up the snow
and form it into a substantially spherical snowball.
A further object of the present invention is to provide a snowball
forming device which eliminates the necessity of the hands coming
into direct contact with the snow.
Still another object of the present invention is to provide an easy
to use toy-like device which is artistic to look at and designed
and adapted for the enjoyment and entertainment of children given
to fun provoking and snow-ball throwing activities.
Other objects and further scope of applicability of the present
invention will become apparent from the detailed description given
hereinafter; it should be understood, however, that the detailed
description and the specific examples, while indicating preferred
embodiments of the invention, are given by way of illustration
only, since various changes and modifications within the spirit and
scope of the invention will become apparent to those skilled in the
art from this detailed description.
Pursuant to the present invention, it has been found that the
above-mentioned disadvantages may be eliminated and an effective
snowball forming procedure may be achieved by utilizing the
snowball forming device of the present invention. The snowball
forming device of the present invention comprises two
semi-spherical cups which, through the use of handle means, are
adapted to be grasped by the left and right hand, respectively, of
the child or young adult engaged in the snowball throwing activity.
According to the present invention, the semi-spherical cups are
grasped in the hands of the user, raked across the surface of a
pile or batch of snow in opposing directions, and the snow scooped
up and trapped in the two semi-spherical cups is formed into a
snowball by bringing the two semi-spherical cups together to form a
sphere. Thus, by scooping the hands containing the device of the
present invention together, a snowball can readily be formed. By
separating the semi-spherical cups, a compressed snowball can be
readily removed therefrom. In making snowballs it is frequently
desirable to trap a substantial quantity of snow between the
semi-spherical cups. Thus, by compressing a large volume of snow
between said cups a compact snowball can be formed which can be
readily removed from said cups. In addition, the frictional force
created by the snow against the inner surface of the cups during
the snow making process produces an amount of heat and surface
melting which further facilitates the removal of the snow from the
semi-spherical cups.
The snowball forming device of the present invention can comprise
identical semi-spherical cups provided with peripheral lip portions
which assist the snowball making individual in guiding the two
semi-spherical cups together to affect the formation of the
snowball. In another embodiment of the present invention, one of
the semi-spherical cups can be slightly smaller than the other so
that as the two cups are pushed together, one of the cups overlaps
the other forming a friction seal. Such an arrangement facilitates
the compression of the snow between the two semi-spherical halves
or cups. This is particularly true in the case where the snowball
forming device is made of a yielding-type of material, such as for
example, a conventional plastic material.
In a still further embodiment of the present invention, one of the
semi-spherical cups can be provided with a groove which is adapted
to receive the other semi-spherical cup. In this embodiment both of
the semi-spherical cups are substantially the same size but one of
the cups is provided with a raised portion which defines a groove
and is adapted to receive the opposing cup. All of the snowball
forming devices of the present invention can readily be provided
with handle means on the outside surface of each of the
semi-spherical cups. Any type of handle means which provides the
snowball forming individual with sufficient control to readily form
snowballs, can be utilized with the device of the present
invention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
The snowball forming device of the present invention comprises two
semi-spherical cups 1 and 2 for scooping up, trapping and
accumulating the potential snowball. The semi-spherical cups are of
a cross section that make it readily adaptable to be held in the
hand of the user. As can readily be seen in FIG. 1, each of the
semi-spherical cups is provided with handle means, such as straps 4
which can be readily attached to the respective semi-spherical cups
by buttons or bolts 5. Each of the cups is provided with lips 3
which provide a surface for guiding the two semi-spherical cups
together during the snowball forming operation.
FIG. 2 shows the embodiment wherein semi-spherical cup 2 is smaller
than semi-spherical cup 1 and accordingly slides inside cup 1 a
distance 9. In this embodiment of the present invention the cups
are advantageously made of a yieldable thermoplastic or
thermosetting material which permits the snowball forming
individual to further compress the cups together. FIG. 2 also shows
another type of handle means having a T-shape. This handle means
contains a gripping portion 6 which is attached to the cups by an
attaching member 7. The handle means can either be integral with
the semi-spherical cups, such as for example, when the cups are
molded of plastic or the handles can be separate units, as shown in
FIG. 3 wherein they are merely screwed into the cups by screw
element 8.
FIG. 4 shows the embodiment of the present invention wherein both
of the semi-spherical cups are substantially identical in size but
cup 1 is provided with an overlapping portion 12 which is adapted
to guide the cup 2 into alignment with cup 1. This arrangement
merely facilitates the snowball forming procedure utilized in the
device of the present invention. FIG. 4 shows a further type of
handle means which can be readily adapted to the device of the
present invention. Thus, handle means 10 having a doorknob-like
shape can be made integral with the semi-spherical cups or, can be
a separate unit as shown in FIG. 5 wherein the handles can be
screwed into the cups through the use of screw element 11. Although
three types of handles are described and shown in the drawings, it
is readily apparent that any type of handle means which is
adaptable to the semi-spherical cups can readily be utilized in the
snowball forming device of the present invention.
FIG. 7 merely shows, in perspective, one of the embodiments of the
snowball forming device of the present invention.
It will be apparent that the device of the present invention can be
made of a variety of materials, such as for example, aluminum,
plastic, including both thermoplastic and thermosetting materials,
aluminum coated with a plastic material, and the like. It is also
readily apparent that the device of the present invention can be
manufactured in a variety of colors and can also be provided with a
cloth-like strap which can be associated with any portion of the
semi-spherical cups to facilitate carrying said cups in one
hand.
The invention being thus described, it will be obvious that the
same may be varied in many ways. Such variations are not to be
regarded as a departure from the spirit and scope of the invention,
and all such modifications are intended to be included within the
scope of the following claims.
