Abstract

An object, such as a soccer ball or a handball, is provided with perforated, interior panels disposed between an interior inflatable bladder and an outer covering which is stitched together from a plurality of individual panels. The stitching process produces raised portions surrounding the interior sides of the outer covering. These raised portions define recesses into which the perforated interior panels are disposed. The recess-filling panels overlie the ridges which are hard and whose hardness is counteracted by these preferably perforated panels. This provides a smooth surface against which the inflatable bladder rests. Additional flexure is also provided by perforating one or more of the layers in the outer covering. With particular reference to handball manufacture the interior panels comprise two layers, the outer one of which contains recesses containing shock absorbing gel type material.

Claims

1. An object for sports play comprising:

a plurality of exterior, stitched together panels sewn at their edges, configured to form a closed volume and forming, by said stitching, raised interior edges at the edges of said panels, whereby each panel has associated therewith a recessed area essentially coextensive with said panel and defined by said raised interior edges;

an inflatable bladder occupying said closed volume;

a first plurality of interior panels in contact with respective ones of said stitched together panels, occupying said recesses and having a plurality of perforations therein, said perforations containing a shock absorbing material; and

a second plurality of interior panels disposed between said bladder and said first plurality of interior panels.

2. The object for sports play of claim 1 in which said second plurality of interior panels include wider portions which cover said interior raised edges.

3. The object for sports play of claim 1 in which said exterior panels include an intermediate layer of perforated material.

4. The object for sports play of claim 1 in which said exterior panels comprise material made of ethyl vinyl acetate.

5. The object for sports play of claim 1 in which said shock absorbing material comprises a polymer.

6. The object for sports play of claim 1 in which said shock absorbing material comprises a gel.

11. The object for sports play of claim 1 in which in which said second plurality of interior panels includes perforations.

12. The object for sports play of claim 11 in which said perforations in said second plurality of interior panels contain shock absorbing material.

7. An object for sports play comprising:

a plurality of exterior, stitched together panels sewn at their edges, configured to form a closed volume and forming, by said stitching, raised interior edges at the edges of said panels, whereby each panel has associated therewith a recessed area essentially coextensive with said panel and defined by said raised interior edges;

an inflatable bladder occupying said closed volume;

a first plurality of interior panels in contact with respective ones of said stitched together panels, occupying said recesses and having a plurality of perforations therein, said projections in said first plurality of interior panels containing material from a gel sheet; and

a second plurality of interior panels disposed between said bladder and said first plurality of interior panels.

8. The object for sports play of claim 7 in which said second plurality of interior panels have wider portions which cover said interior raised edges.

9. The object for sports play of claim 7 in which said exterior panels include an intermediate layer of perforated material.

10. The object for sports play of claim 7 in which said exterior panels comprise material made of ethyl vinyl acetate.

13. The object for sports play of claim 7 in which said perforations in said second plurality of interior panels contain material from a gel sheet.
