BALL HOCKEY STICK WITH CURVILINEAR STRIKING FACES
Abstract
The ball hockey stick of this invention includes an elongate
shaft having a blade, preferably molded from a rigid plastic,
affixed at one end thereof. The blade is provided with concave
ball-contacting faces to substantially eliminate the tendency for
the ball to bounce or roll over the top edge. The concavity
adjacent the heel of the blade is of a parabolic form which merges
into the generally spherical concavity of the forward end.

Parent Case Text
This application is a continuation-in-part of my previously filed
application, Ser. No. 810,177, filed Mar. 25, 1969, now abandoned.
Claims
What is claimed is:
1. A ball hockey stick comprising a shaft and an elongated blade in
which:
a. said blade has an upstanding shank portion for receiving and
securing said shaft thereto;
b. said blade further having a neck portion and a striking portion
with said neck portion intermediate said shank and said striking
portions;
c. said neck and striking portions lying in the same plane
generated by the longitudinal axis of said blade;
d. said neck portion having a dished area of parabolic
configuration with the vertex of the paraboloid located adjacent to
the heel of said blade;
e. said neck portion further having upper and lower rims
encompassing said dished area;
f. said striking portion being substantially circular in shape
within said plane and larger in diameter than said neck portion and
having a dished face of concave, spherical configuration which
merges with said dished area of said neck portion;
g. said dished face forming a contiguous marginal rim encompassing
said striking portion and merging with said upper and lower rims of
said neck portion; and
h. the depths of said dished face and said dished area being
substantially equal.
2. The ball hockey stick as defined in claim 1 wherein the blade
portions and configurations are symmetrical about said longitudinal
axis of said blade.
3. The ball hockey stick as defined in claim 1 wherein the blade is
made from plastic material.
4. The ball hockey stick as defined in claim 1 wherein said shaft
is round in cross-section.
5. The ball hockey stick as defined in claim 1 wherein said shaft
is rectangular in cross-section.
Description
In the following detailed description, reference is made to the
drawings wherein:
FIG. 1 is a general view of the hockey stick embodying features of
the present invention;
FIG. 2 is a sectional view taken on the line 2--2 of FIG. 1;
and
FIG. 3 is a sectional view taken on the line 3--3 of FIG. 1.
The hockey stick 10 comprises a blade 12 pinned to a shaft 14, the
shaft 14 having a handle portion 16 extending therefrom in
substantially straight line relation. The blade 12 has a shank 18
in which the shaft 14 is secured by means of the pin 20; an
adhesive may be used in conjunction therewith or as a substitute
therefor. A neck 22 connects the shank 18 with the striking portion
24 and to provide an extended ball-contacting area.
The illustrated embodiment is a symmetrical structure, so that it
may be used by either right-handed or left-handed players and to
provide two ball-contacting faces for advancing the ball. The
description that follows will deal with only one side of the blade
12 for simplification of reference.
The striking portion 24 is provided with a dished face 26 formed by
generating an imaginary sphere on an axis through the center
thereof. The dished face 26 merges with a dished area 28 in the
neck 22, the dished area 28 being formed by generating an imaginary
paraboloid on an axis angularly disposed to the axis of the blade
12 whereby the generator of the paraboloid, when horizontal and
adjacent to the neck 22, is substantially parallel with the axis of
the blade 12, as may be seen particularly from FIG. 2. The vertex
of the paraboloid is adjacent to the heel of the blade 12. The
maximum depths of the concavity of the dished face 26 and the
dished area 28 are substantially the same.
The dished face 26 is particularly suited for providing directional
control when striking a ball, as in passing a ball to a team-mate
or in shooting on goal. The neck 22 provides an extended area for
receiving a passed ball and for advancing, or stick-handling, the
ball through the ranks of the opposing players. The upper rim 32
substantially eliminates the tendency for the ball to bounce or
roll over the top edge of the blade 12 during vigorous play, as is
the case with conventional hockey sticks when used to play ball
hockey.
The marginal rim 30 of the striking portion 24 merges into upper
and lower rims 32, 34, which define the neck 22. The rims 30, 32,
34, provide structural rigidity as well as greater control of the
ball during play.
The use of a plastic such as polyethylene provides a suitably stiff
blade 12, while use of the ball hockey stick is enhanced by the
virtual absence of scuff marking attendent with use of such plastic
during indoor or deck play. The shaft 14 may be of any suitable
material, such as wood or metal tubing, and either round or
rectangular in cross-section. The handle 16 is also of well known
structure.
