Abstract
Abstract A cap construction including an exterior layer coextensive with an interior layer defining an cap-shaped structure including an elastomeric band to enhance securement of the structure overlying a swimmer's head portion. Sandwiched between the layers are a matrix of enclosed pneumatic chambers to afford a protective covering to the swimmer in use. A modification of the instant invention includes a plurality of coaxially aligned pneumatic chambers directed exteriorly through the opposed layers defining an elongate chamber defined by an ellipse of revolution. A further modification of the instant invention includes a series of spherical chambers captured between the layers including interconnecting conduits, wherein the conduits are secured at intersections with each pneumatic sphere defining a medial axis about each intersection with apertures directed through the conduits interiorly of the pneumatic chambers, or spheres to permit equalization of pressure throughout the matrix of spheres.

A swimming cap defined by a hollow cavity receiving an individual's head within the cap and utilizing flexible fluid impermeable material including, an outer liner coextensively formed to an inner liner, wherein the outer and inner liners each terminate in a central opening defined by a continuous elastomeric band formed about the opening, and a matrix of pneumatic chambers secured between the inner and outer liner, and wherein the inner liner includes a matrix of inner liner openings, the inner liner openings coaxially aligned with the pneumatic chambers to permit projection of the pneumatic chambers through the inner liner openings, and wherein the pneumatic chambers are spherical, and including equally spaced rows of conduits coaxially intersecting the spherical pneumatic chambers, and further including equally spaced columns of conduits intersecting the pneumatic chambers, wherein the columns and rows of conduits intersect each other orthogonally, and wherein each of the spherical pneumatic chambers is geometrically formed about an intersection of the rows and columns of conduits, and wherein intersections of the rows and columns of conduits are defined by an integral association of the respective rows and columns of conduits within each respective spherical pneumatic chamber, and including conduit openings directed through the rows and columns of conduits confined interiorly within the respective spherical pneumatic chambers to permit equalization of pneumatic pressure between the spherical pneumatic chambers, and wherein the pneumatic chambers are mounted to an intermediate liner, and the intermediate liner coextensively mounted between the inner and outer liner, and further including a second intermediate liner, with the second intermediate liner including a second matrix of spherical chambers, each second spherical chamber of the matrix of second spherical chambers coaxially aligned with each first pneumatic chamber of the first matrix of spherical chambers, and wherein the outer liner includes liner apertures coaxially aligned with the inner liner apertures, and wherein the second matrix of pneumatic chambers project exteriorly of the outer liner apertures.
