DETAILED DESCRIPTION

(19) An exercise ball device 10 is shown in FIGS. 1 thru 13. The exercise ball device 10 comprises or consists of a frame 12 comprising multiple frame members 14 connecting together at multiple nodes (e.g. six (6) frame members 14 connected together at four (4) nodes 16).

(20) A frame cross-member 18 connects together two (2) opposed frame members 14 to increase the rigidity and strength of the frame 12. The frame 12 can be a three (3) dimensional space frame that can be spherical-shaped like a ball. The frame 12 can be substantially rigid to rigid and made, for example, by forming (e.g. extruding, molding, injection molding), or machining a pre-form or block of material. The frame 12 can be made of plastic material (e.g. nylon, polyethylene, polypropylene, acrylonitrile butadiene styrene (ABS), or suitable plastic material, fiberglass, carbon fiber, boron fiber, Kevlar, or other suitable composite material). Alternatively, the frame can be made of metal (e.g. aluminum, titanium, metal composite), or made of multiple materials (e.g. metal frame overmolded with plastic material, frame constructed of metal and/or plastic parts.

(21) The frame 12 can comprise six (6) frame members 14 connecting together at four (4) nodes defining four (4) openings 20 to into an interior (i.e. interior space) of the frame 12. The frame members 14 define and surround the openings 20, and support and accommodate the four (4) panels 22. The panels 22 can be the same size and shape. For example, each panel 14 can be approximately one-quarter of an outer surface layer of a sphere (i.e. four (4) quadrants). Further, the panels 22 are sized and shaped to fit into the openings 20 between the frame members 14 (i.e. the perimeter edges of the panels 22 dimensionally fit between the frame members 14 defining the openings 20).

(22) The frame 12 can comprise one or more flanges 24 provided around a perimeter of each of the openings 20 (e.g. continuous flange). Alternatively, the flanges 24 can be provided at portions or sections of each opening (e.g. discontinuous flange members or sections). As shown in FIG. 8, the flanges 24 are continuous, except for a portion or section of the frame adjacent the attachment points of the frame cross member 18 with the frame members 14. Further, the flanges 24 (e.g. side flanges 24) extend outwardly from the sides of the frame members 14. In addition the flanges 24 can be located below the outer surfaces of each frame members 14. This arrangement results in the panels 22 being at least partially located below the outer surface of the frame members 14 (i.e. the panels recessed below outer surface of frame members 14). For example, the base of the panels (i.e. the lower base or base layers) are recessed below or flush with the outer surfaces of the frame members while the spikes 32 extend above the outer surfaces of the frame members.

(23) The exercise ball device 10, comprises a three-dimensional space frame comprising multiple frame members 14 defining multiple the openings 20 into the interior (i.e. interior space) of the frame 12. The multiple panels 22 connect to the frame members 12, and the panels 12 are disposed within the openings 20 and located between the frame members 12. The panels 22 can be recessed below an outer surface of the frame members 14, and the frame members 14 together with the panels 22 defining an outer surface of the exercise ball device 10. Alternatively, the height of the side flanges 26 on the frame members 14 can be adjusted (e.g. raise) so that the outer surface of the frame member 14 are flush with the outer surfaces of the panels 22.

(24) The flanges 24 can cooperate with, connect to, and support the edges of the panels 22, in particular with the inner surface of the panels 22 located adjacent to the perimeter edges thereof. As shown in FIG. 12, two (2) adjacent panels 22 are connected to the frame 12, for example, by adhesive applied (e.g. adhesive layer 25) to the flanges 24, which adhesive bonds with the respective edges of the panels 22. Alternatively, the panels 22 can be heat welded, molded, overmolded, fastened, taped (e.g. double sided tape), or connected to the frame by other suitable devices and/or methods.

(25) The construction of the panel 22 is shown in detail in FIGS. 10, 11, and 13. The panel 22 can comprise an inner support panel 22a connected to an outer cover panel 22b. For example, the inner support panel 22a can be molded, and the outer cover panel 22b can be overmolded onto the inner support panel 22a.

(26) The inner support panel 22a comprises a flange 26 (i.e. raised or increased thickness portion) provided around a perimeter of the inner support panel 22a. The flange 26 of the inner support panel 22a can cooperate with and be connected (e.g. adhered) to the flange 24 of the frame 12. All four (4) panels 22 can be connected to the frame 22 in this manner to complete the construction or assembly.

(27) The inner support panel 22a can be provided with multiple through holes 28, as shown in FIG. 11, for example, as seen on the cross-sectioned edge of the panel 22. The through holes 28 can be provided in a pattern (e.g. through holes 28 spaced apart by equal distances from each other in a geometrical pattern, matrix or grid).

(28) As shown in FIG. 13, the through holes 28 can widen (e.g. by beveling, tapering, stepping) in a radial direction towards a center of the exercise ball device 10 (i.e. the through holes become wider in a direction from the outer surface towards the inner surface of the inner support panel 22a). This arrangement results in an anchoring head 30 being formed during molding inside the through hole 28 when the outer cover panel 22b is overmolded onto the inner support panel 22a.

(29) The panels 22 can each be made by first injection molding the inner support panel 22a, for example, made of nylon material. Then each molded inner support panel 22a is overmolded (e.g. by insert molding) with the outer cover layer 22b made of soft plastic or thermoplastic elastomer material. This can result in the inner support panel 22a being bonded to the outer cover layer 22b. Further, the molded thermoplastic elastomer material when being molded flows and enters into the plurality of through holes 28 creating multiple anchors for mechanically fastening the outer cover layer 22b to the inner support layer 22a.

(30) The outer cover layer 22b of the panels 22 can be textured (e.g. by molding). For example, a plurality of spikes 32 can be provided when molding the outer cover layer 22b. For example, the spikes 32 can protrude above the outer surfaces of the frame members, as shown in FIG. 12.

(31) The exercise ball device 10 can be made by making the frame 12 (e.g. injection molding) and the panels 22 (e.g. injection molding), and then assembling these parts or components together. For example, the panels 22 can be connected or attached to the flanges 24 of the frame 12, for example, using adhesive material resulting in an adhesive layer 25 being located between each flange 24 and each panel 22. Specifically, the adhesive layer 25 is provided between the upper surface of each flange 24 and the lower surface adjacent the edge of each panel 22.

(32) Optionally, the exercise ball device 10, for example, can be filled with a resilient material (e.g. shredded rubber) to add weight thereto.

(33) In the exercise ball device 10 shown in FIGS. 1 thru 13, an outer surface of each frame member 14 is exposed when assembled. Further, as shown in FIG. 13, the outer surface of each frame member 14 is recessed (i.e. located below the height of the outer surface of the protrusions 32).

(34) Further, the base or base layer of the panels 32 can be located below (i.e. recessed below) the outer surfaces of the frame members 14, as shown in FIG. 12, or alternatively, can be flush therewith.

(35) Another exercise ball device 110 is shown in FIG. 14. The panels 122 can be configured to abut each other and cover each frame member 122. For example, the flanges 124 can be raised on each frame member 114, and the panels 122 can be made to extend inwardly so as to cover each frame member 122 and abut each other. In this manner, the frame 112 is completely hidden under the panels 22 compared with the construction of the exercise ball shown in FIGS. 1 and 8.
