Abstract

The invention disclosed and claimed here is a padded inflatable game ball. The ball is a seamed ball consisting of a spherical rubber bladder, a layer of winding surrounding the bladder, a cellular sponge layer surrounding the winding, and seams and external skin panel sections surrounding the cellular sponge layer. The sponge layer provides padding under the skin panel sections. The seams are made of narrow strips of high density rubber which cover a relatively small section of the overall surface area of the sponge layer. This allows outgassing of the sponge layer as it is foamed during the ball manufacturing process.

Claims

1. A padded inflatable ball, comprising:

an inner carcass portion defining the shape of the ball;

a cellular sponge layer surrounding the inner carcass portion;

a plurality of raised seams defined by strips of a seam material, wherein the sponge layer underlies the raised seams, and further, the inner carcass portion, the cellular sponge layer and raised seams together define a ball carcass;

a plurality of skin panels attached to the ball carcass between the seams; and

further, each strip of seam material comprises;

a raised portion positioned between spaced, outer edges of the skin panels on opposite sides of the raised portion; and

flange portions extending away from opposite sides of the raised portion, the flange portions underlying at least the outer edges of the skin panels and being sandwiched between the skin panels and the cellular sponge layer.

2. The ball of claim 1, wherein the inner carcass portion comprises an inflatable bladder and a layer of winding surrounding the inflatable bladder.

3. A ball carcass for a padded inflatable ball, comprising:

an inner carcass portion defining the shape of a ball, a cellular sponge layer surrounding the inner carcass portion, a plurality of raised seams defined by strips of a seam material, wherein the strips of seam material are bonded directly to the cellular sponge layer and the sponge layer underlies the strips of seam material, the seam material strips being arranged relative to the sponge layer so that areas of the sponge layer are exposed between the seam material strips, and wherein the inner carcass portion, the cellular sponge layer and raised seams together define the ball carcass.

4. The ball of claim 3, wherein the inner carcass portion comprises an inflatable bladder and a layer of winding surrounding the inflatable bladder.

5. A padded inflatable ball, comprising:

an inflatable bladder;

a layer of winding surrounding the inflatable bladder;

a cellular sponge layer substantially surrounding the layer of winding;

a plurality of raised seams defined by strips of a seam material attached to the cellular sponge layer, the raised seams defining the boundaries of skin panel placement areas; and

a plurality of skin panels attached to the skin panel placement areas so that the panels are separated by the raised seams, and, wherein, each strip of seam material includes a raised portion positioned between spaced, outer edges of the skin panels on opposite sides of the raised portion, and each strip includes flange portions underlying at least the outer edges of the skin panels and sandwiched between the skin panels and the cellular sponge layer.
