Abstract

An inflatable game ball and a method of constructing an inflatable game ball is described. Panel segments are formed from an outer panel portion and an inner panel portion having different sizes, with the inner panel portion being smaller than the outer panel portion. The inner panel portion and the outer panel portion are joined so that peripheral edges of the inner panel portion and the outer panel portion are aligned. Multiple panel segments are attached together to form a cover. Due to the differences in sizes between the inner panel portion and the outer panel portion, when an inflatable bladder within an interior of the cover is inflated to a fully inflated condition, variations in the dimensions of the ball caused by stretching of the cover may be reduced or minimized. In one embodiment, an alignment guide can assist with aligning the peripheral edges of the panel portions.

First claim

What is claimed is:

1. A method of constructing an inflatable game ball, the method comprising:
removing a plurality of outer panel portions from a first material, each of the outer panel portions having a first shape and a first size;
removing a plurality of inner panel portions from a second material, each of the inner panel portions having the first shape and a second size, the second size being smaller than the first size;
joining the plurality of outer panel portions to the plurality of inner panel portions along a contact interface of respective peripheral edges to form a plurality of panel segments, each panel segment having the peripheral edge of one of the plurality of outer panel portions aligned with the peripheral edge of one of the plurality of inner panel portions, and wherein the peripheral edge of the outer panel portions is parallel to the peripheral edge of the inner panel portions at the contact interface for each panel segment;
attaching the plurality of panel segments together along the aligned peripheral edges to form a cover of the inflatable game ball;
wherein the first size is associated with a first length in a longitudinal direction along a major axis of each one of the outer panel portions and a first width in a lateral direction along a minor axis of each one of the outer panel portions;
wherein the second size is associated with a second length in the longitudinal direction along a major axis of each one of the inner panel portions and a second width in the lateral direction along a minor axis of each one of the inner panel portions;
wherein the second length is smaller than the first length and the second width is smaller than the first width;
associating an inflatable bladder in a deflated condition within an interior of the cover;
inflating the inflatable bladder to a fully inflated condition;
wherein when the inflatable bladder is in the deflated condition, an interior surface of the outer panel portions is separated a first distance apart from a top surface of the inner panel portions; and
wherein when the inflatable bladder is in the fully inflated condition, the interior surface of the outer panel portions is in contact with the top surface of the inner panel portions.

2. The method according to claim 1 , wherein a difference between the first length and the second length is substantially equal to a difference between the first width and the second width.

3. The method according to claim 1 , wherein a difference between the first length and the second length is smaller than a difference between the first width and the second width.

4. The method according to claim 1 , wherein the step of joining the plurality of outer panel portions to the plurality of inner panel portions includes forming a concave surface on each outer panel portion that bulges outwards from the center of each inner panel portion.

5. The method according to claim 4 , wherein the concave surface is disposed a first distance apart from the inner panel portion.

6. The method according to claim 5 , wherein the first distance is approximately equal to a difference between the first size and the second size.

7. The method according to claim 1 , wherein the step of joining comprises applying adhesive along at least one of the peripheral edge of the first inner panel portion and the peripheral edge of the first outer panel portion.

8. A method of constructing an inflatable game ball, the method comprising:
providing a first outer panel portion removed from a first material, the first outer panel portion having a first shape and a first size,
providing a first inner panel portion removed from a second material, the first inner panel portion having the first shape and a second size, the second size being smaller than the first size;
providing an alignment guide having the first shape and associated with an interior dimension that is substantially similar to the second size;
placing the first inner panel portion into the interior of the alignment guide such that a peripheral edge of the first inner panel portion is adjacent to an inner surface of the alignment guide;
placing the first outer panel portion into the interior of the alignment guide such that a peripheral edge of the first outer panel portion is disposed against the inner surface of the alignment guide;
joining the first inner panel portion to the first outer panel portion along a contact interface between the respective peripheral edges to form a panel segment, the panel segment having the peripheral edge of the first outer panel portion aligned with the peripheral edge of the first inner panel portion, wherein the peripheral edge of the first outer panel portion is parallel to the peripheral edge of the first inner panel portion at the contact interface;
attaching together a plurality of panel segments along the aligned parallel peripheral edges to form a cover of the inflatable game ball;
associating an inflatable bladder in a deflated condition within an interior of the cover;
wherein when the inflatable bladder is in the deflated condition, an interior surface of the first outer panel portion is separated a first distance apart from a top surface of the first inner panel portion; and
wherein when the inflatable bladder is in a fully inflated condition, the interior surface of the first outer panel portion is in contact with the top surface of the first inner panel portion.

9. The method according to claim 8 ,
wherein the first size is associated with a first length in a longitudinal direction along a major axis of the first outer panel portion and a first width in a lateral direction along a minor axis of the first outer panel portion;
wherein the second size is associated with a second length in the longitudinal direction along a major axis of the first inner panel portion and a second width in the lateral direction along a minor axis of the first inner panel portion; and
wherein the second length is smaller than the first length and the second width is smaller than the first width.

10. The method according to claim 8 ,
wherein the step of joining comprises applying adhesive along at least one of the peripheral edge of the first inner panel portion and the peripheral edge of the first outer panel portion; and
wherein the adhesive is configured to temporarily align the peripheral edge of the first outer panel portion and the peripheral edge of the first inner panel portion until the step of attaching.

11. The method according to claim 8 , wherein the first material includes leather and the second material includes a flexible fabric.

12. The method according to claim 8 , wherein the step of joining the first outer panel portion to the first inner panel portion includes forming a concave surface on the first outer panel portion that bulges outwards from the first inner panel portion.

13. The method according to claim 12 , wherein the concave surface is disposed a first distance apart from the first inner panel portion.

14. A method of constructing an inflatable game ball, the method comprising:
removing a plurality of outer panel portions from a first material, each of the outer panel portions having a first shape and a first size, wherein the first material includes leather;
removing a plurality of inner panel portions from a second material, each of the inner panel portions having the first shape and a second size, the second size being smaller than the first size, wherein the second material includes a flexible fabric;
joining the plurality of outer panel portions to the plurality of inner panel portions along a contact interface of respective per
