Exercise weight system
View Patent ↗An exemplary incremental weight for an exercise system has a generally annular magnet encapsulated within a coating which cushions the magnet, protecting it both from becoming damaged, and from damaging an exercise apparatus, while promoting the adhesive properties of the magnet. In a first exemplary embodiment, the coating comprises a first annular rib and a second annular rib extending respectively about outer and inner peripheries of the generally annular magnet, and a plurality of ribs extending radially between the first and second annular ribs. The generally annular magnet, in exemplary embodiments, comprises at least one of a ceramic magnet, ferrite, or an alnico magnet. Exemplary coatings may be elastomeric, molded silicone, or anti-slip coatings. In another exemplary embodiment, a plurality of mounting pads are attached to a surface of said weight defined by an annular surface of said magnet.

a unitary annular magnet having an annular surface; and
a non-magnetic coating encapsulating at least a portion of said annular surface of said magnet, the coating having an integrally formed extension from said annular surface to form an adhesion surface.
2. An incremental weight according to claim 1 , wherein said annular magnet comprises a ceramic magnet.
3. An incremental weight according to claim 1 , wherein said ceramic magnet comprises ferrite.
4. An incremental weight system according to claim 1 , wherein said annular magnet comprises an alnico magnet.
5. An incremental weight system according to claim 1 , wherein said coating comprises an elastomer.
6. An incremental weight system according to claim 1 , wherein said coating comprises molded silicone.
7. An incremental weight system according to claim 1 , wherein said coating further comprises an anti-slip coating.
8. An incremental weight system according to claim 1 , wherein said integrally formed extension of said coating comprises a plurality of mounting pads attached to a surface of said weight defined by an annular surface of said magnet.
9. An incremental weight system according to claim 8 , wherein said mounting pads comprise an elastomer.
10. An incremental weight system according to claim 1 , wherein said coating encapsulates the entire surface of said generally annular magnet.
11. An incremental weight system according to claim 1 , wherein said integrally formed extension of said coating comprises at least one annular rib extending about an outer periphery of said generally annular magnet.
12. An incremental weight system according to claim 1 , wherein said integrally formed extension of said coating comprises at least a first annular rib extending about an outer periphery of said generally annular magnet, and at least a second annular rib extending about an inner periphery of said generally annular magnet.
13. An incremental weight system according to claim 12 , wherein said integrally formed extension of said coating further comprises a plurality of ribs extending radially between said first annular rib and said second annular rib.
14. An incremental weight system according to claim 1 , wherein said coating comprises a polarity indexing indicium.
15. A weight training system, comprising:
a primary weight training device fabricated at least in part from ferrous material; and
at least one incremental weight which may be applied selectively to said primary weight training device, with said incremental weight comprising:
a unitary annular magnet having an annular surface; and
a non-magnetic coating encapsulating at least a portion of said annular surface of said magnet, the coating having an integrally formed extension from said annular surface to form an adhesion surface.
16. A weight training system according to claim 15 , wherein said primary weight training device comprises a dumbbell.
17. A weight training system according to claim 15 , wherein said primary weight training device comprises a barbell.
18. A weight training system according to claim 15 , wherein said primary weight training device comprises a flat plate apparatus.
19. A weight training system according to claim 15 , wherein said coating comprises an elastomeric coating having a plurality of generally annular ribs extending about inner and outer peripheries of said generally annular magnet.
20. An incremental weight for an exercise system, comprising:
a unitary annular magnet having a surface, said unitary annular magnet comprising at least one of: a ceramic magnet, ferrite, or an alnico magnet; and
an a non-magnetic elastomeric coating encapsulating the surface of said magnet, said non-magnetic elastomeric coating comprising a first annular rib extending from the surface and about an outer periphery of said unitary annular magnet, a second annular rib extending from the surface and about an inner periphery of said unitary annular magnet, and a plurality of radial ribs extending from the surface of said unitary annular magnet and radially between said first annular rib and said second annular rib.
