BALL HOCKEY STICK WITH CURVILINEAR STRIKING FACES
United States Patent 3720410
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.

Claims:
What is claimed is
1. A ball hockey stick comprising a shaft and an elongated blade in which:
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.
