Claims
We claim:
1. A hockey puck suitable for practice on non-ice smooth surfaces,
said puck having substantially the size and shape as a conventional
hockey puck and including a cylindrical body of felt and a ballast
weight within said body, the diameter of said cylindrical body
being greater than its height.
2. A puck according to claim 1 wherein the ballast weight is
cylindrical.
3. A puck according to claim 2 wherein the body has a central bore
with the ballast weight located therein.
4. A puck according to claim 3 wherein the bore is closed by a felt
plug.
5. A puck according to claim 4 wherein the plug is secured in the
bore by adhesive.
6. A puck according to claim 1 wherein the outer surfaces of the
body are treated with water repellent.
Description
This invention relates to hockey pucks which can be used for
practice purposes on smooth surfaces other than ice.
Since it is not easy for ice hockey players, especially young
players, to obtain access to an ice rink for practice as often as
and when they wish, previous attempts have been made to provide a
puck which can be used on smooth surfaces other than ice, for
example a gymnasium floor, and which matches the behaviour of a
standard puck on ice as closely as possible.
Previous proposals of this nature have not been successful for
several reasons. They have not behaved on smooth surfaces like a
standard puck on ice, or they have been mechanically complicated,
for example by being provided with some kind of roller arrangement,
or they have been too hard for safe use outside of an ice rink with
the likelihood of causing damage to persons and property.
It has now been found, according to the present invention, that a
very satisfactory practice puck can be provided by making the body
of the puck of felt and including a ballast weight within the felt
body. The ballast weight may be positioned in a central bore in the
felt body, and a plug of felt secured in the bore by a suitable
adhesive to retain the ballast weight in place.
The outer surfaces of the felt body may be treated with a water
repellent to minimize moisture absorption and still retain the
original felt characteristics.
One embodiment of the present invention will now be described, by
way of example, with reference to the accompanying drawings, of
which:
FIG. 1 is a perspective view of a puck,
FIG. 2 is a plan view,
FIG. 3 is a sectional view along the line 3--3 of FIG. 2, and
FIG. 4 is a plan view of the ballast weight.
Referring to the drawings, a practice puck has a one-piece
cylindrical body 11 of felt, the thickness and diameter of which
correspond to the size of a standard puck for use on ice, the
thickness therefore being about one inch and the diameter about
three inches. The body 11 has a central bore 12 extending partway
through the body 11 from one face thereof. In this case, the bore
12 has a diameter of 1.25 inches and a depth of 0.625 inches.
A cylindrical ballast weight 13 of steel or weighted plastic is
positioned at the bottom of the bore 12. The diameter of the
ballast weight 13 corresponds to the diameter of the bore 12, and
the thickness of the ballast weight 13 is 0.25 inches. A felt plug
14 is also positioned in the bore 12. The plug 14 has a diameter
corresponding to that of the bore 12, and has a thickness of 0.375
inches so that one end of the plug 14 contacts the ballast weight
13 and the other end of the plug is flush with the face of the body
11 from which the bore 12 extends. The plug 14 is retained in place
in the bore 12 by a suitable adhesive, for example contact cement,
thereby also retaining the ballast weight 13 in its centrally
located position within the felt body 11 of the puck.
In this case, the weight of the felt body 11 and felt plug 14 is
1.25 oz., and the weight of the ballast weight is 1.75 oz. The
total weight of the puck is therefore 3 oz., which is less than the
official weight of a puck for use on ice. The lesser weight of the
practice puck enables it to have the desired rebound and
directional control, with a minimum of risk of property damage or
injury to people. The ballast weight 13 provides the desired
kinetic energy.
A suitable felt for the body, having the desired resiliency,
rebound and weight characteristics has an equivalent S.A.E. number
of F3, with 90% minimum wool content, a maximum tensile strength of
400 p.s.i. and a splitting resistance of 22. A suitable felt for
the plug 14 has an equivalent S.A.E. number of F5, with 95% minimum
wool content, a minimum tensile strength of 400 p.s.i. and a
splitting resistance of 18.
Advantageously, the exterior surfaces of the body 11 and plug 14
are treated with a water repellent, a suitable treatment being by
spraying with a high density silicone agent which does not change
the softness of the original felt material.
When used on a non-ice smooth surface, the felt puck behaves in a
manner very similar to a standard puck on ice, and yet is much less
likely to cause damage to people and objects with which it comes in
contact than prior non-ice pucks. The actual weight of the ballast
weight 13 has been determined to provide the desired balance,
rebound and directional control.
The puck may also be used on an ice surface, although it is not of
course primarily designed for this purpose.
If desired, the bore 12 could extend completely through the body
11, with a plug 14 being provided above and below the ballast
weight 13.
