DETAILED DESCRIPTION
With reference to
FIGS. 1-3
, the invention relates to a pad
10
that is particularly suitable for use with a sporting helmet, such as a football helmet. The pad includes as its components a disk
12
(
FIG. 4
) of a polymeric material, a cushion
14
(FIG.
5
), attachment member
16
(
FIG. 6
) and covering portions
18
(
FIG. 7
) and
20
(FIG.
8
).
The disk
12
is preferably a donut-shaped portion of a substantially rigid plastic material, preferably having a thickness of from about {fraction (1/32)} to about {fraction (3/32)} of an inch, most preferably about {fraction (1/16)} of an inch. The disk
12
is preferably elliptical (egg-shaped) or circular (as shown in FIG.
4
). For an elliptical disk, it is preferred that the major diameter is from about 4 to about 6 inches, most preferably about 5 inches, and the minor diameter is from about 4 to about 4½ inches, most preferably about 4¼ inches. For a circular disk
12
, the disk
12
preferably has a diameter of from about
4
to about 6 inches, most preferably about 5 inches.
The disk
12
further includes a central cutout portion
22
that is preferably either elliptical or circular, with its diameter dimensions ranging from about 2 to about 4 inches, most preferably about 2½ inches for a circular cutout portion. An elliptical cutout portion preferably has a major diameter of about 2½ inches and a minor diameter of about 2 inches.
The cushion
14
is preferably a half-circle of a foam material having a thickness of from about ⅛ to about ½ inch, most preferably about ¼ inch. The cushion
14
is sized to overlie approximately one-half of the disk
12
and includes opposite face surfaces
24
and
25
, one of which is preferably securable, as by adhesive, to the disk
12
.
The attachment member
16
is preferably provided by a U-shaped strip of a flexible sheet material, such as a plastic material
26
, onto which is secured a plurality of snap members
28
configured to matingly engage corresponding snap members affixed to an inner surface of a helmet with which the pad is to be used. For example, the snap members
28
may be female snap members for engaging male snap members on the helmet. The plastic material
26
has opposite sides
30
and
31
. The snap members
28
have two portions, one of which is positioned on either side of the plastic material, and press-fit together to secure the snap members
28
to the plastic material
26
. The attachment member
16
is secured to the pad
10
by securing the side
31
to a portion of the covering
18
.
The covering portions
18
and
20
are provided by portions of a flexible sheet material, such as vinyl. The portion
18
is preferably circular or elliptical in shape and the portion
20
is generally diamond-shaped.
The portion
18
further includes a central cutout portion
32
that is preferably either elliptical or circular.
With reference to
FIGS. 9
a
-
9
d
, the pad
10
is preferably assembled by folding the disk
12
(with the cushion
14
secured thereto) about its center-line to impart a crease
34
at the center-line of the disk
12
. The crease
34
remains, with the disk relaxing in the absence of pressure so that free edges
36
and
38
of the disk
12
are spaced a distance D of from about 1½ to about 2½ inches. Accordingly, imparting the crease
34
renders the disk
12
bent to provide sides
40
and
42
which are yieldably positionable relative to one another.
The thus assembled pad
10
is then enclosed within a covering provided by the covering portions
18
and
20
. With the disk
12
squeezed together so that the distance D is slightly less than its fully relaxed dimension, the covering portions
18
and are positioned around the disk
12
and sewn as by stitching
44
or otherwise joined together so that the disk
12
is fully encased. In this regard, the portion
18
is preferably positioned so that the cutout
32
overlies the cutout
22
of the disk. As will be appreciated, the portion
18
substantially overlies the flat surfaces of the disk
12
. The portion
20
is positioned to that it extends around the remaining exposed portion of the disk
12
. The meeting edges of the covering portions
18
and
20
are then secured together, as by stitches, and the cutout
32
closed as by stitching the edges thereof together. The attachment member
16
is then secured to a portion of the covering portion
18
opposite the cushion
14
, as by adhesively securing the side
31
to the covering.
Turning to
FIG. 10
, the assembled pad
10
may then be installed on a helmet
50
. The helmet
50
preferably includes attachment members
52
secured to an inner surface of the helmet adjacent portions of the helmet interior so that they will be adjacent jaw areas of a user wearing the helmet. The female snap members
28
frictionally engage the male members
52
to enable the pad
10
to be retained in position on the helmet.
As will be appreciated, the sides
40
and
42
of the assembled pad
10
are yieldably positionable relative to one another within a range of motion defined by the relative positions of the edges
36
and
38
. That is, in the absence of pressure upon the pad, the distance D between the edges
36
and
38
will be their relaxed distance, or slightly less, if the covering is installed in a manner which slightly urges or squeezes the edges toward one another. This distance is preferably from about 1½ to about
2
½ inches for a jaw pad for use with an adult-sized football helmet.
As will be appreciated, the crease will tend to maintain the edges
36
and
38
at their maximum spacing. When a force is exerted upon the pad, as by a user receiving force applied to the jaw area of the helmet, this force will tend to urge the sides
36
and
38
toward one another. Thus, force is transferred to overcome the bias of the crease
22
and urge the sides
40
and
42
toward one another. In the presence of sufficient force, the sides
40
and
42
will contact one another so that the relative spacing between the edges
36
and
38
is zero. At this point, in the presence of sufficient force to overcome the compressive resistance of the cushion, the cushion may compress further absorbing force and reducing force applied to the jaw of the user.
The foregoing description of certain exemplary embodiments of the present invention has been provided for purposes of illustration only, and it is understood that numerous modifications or alterations may be made in and to the illustrated embodiments without departing from the spirit and scope of the invention as defined in the following claims.
