Variable weight exerciser

Claim 2

A variable weight exerciser comprising: a primary elongated bar; one or more substantially straight secondary elongated bars of lesser width than said primary elongated bar for insertion in and withdrawal from said primary elongated bar, said primary bar being adapted to receive therein one or more of said secondary bars; and means operable for securing said secondary bars inserted within said primary bar and for permitting the withdrawal of said secondary bars inserted within said primary bar.

Claim 3

The exerciser of claim 1 wherein the width of said secondary bars is less than half the width of said primary bar and said primarY bar is adapted to receive therein one or more pairs of said secondary bars in an opposing relationship to retain at least a portion of the transverse balance of said primary bar.

Claim 4

The exerciser of claim 1 wherein said primary bar has a plurality of holes formed therein, each hole extending longitudinally along the length of said primary bar, to receive said secondary bars and said secondary bars are substantially immobile with respect to said primary bar when secured therein.

Claim 5

The exerciser of Claim 1 wherein said means for securing said secondary bars includes a rod extending from the end of said exerciser and having at least a portion thereof threaded, and an end cap adapted to be threaded on said rod and operable for preventing the withdrawal of said secondary bars.

Claim 6

The exerciser of claim 4 wherein said end cap is of lesser diameter than said exerciser and the end of said exerciser is recessed to receive said end cap.

Claim 7

The exerciser of claim 4 wherein said exerciser has a hole in the end thereof opposite said rod and compatible with said rod, and said rod extends beyond said end cap whereby a plurality of said exercisers may be loosely joined to one another.

Claim 8

The exerciser of claim 6 wherein said rod has threads that extend beyond said end cap and said hole is threaded and compatible with said rod, whereby a plurality of said exercisers may be firmly joined to one another.

Claim 9

The exerciser of claim 1 wherein said primary bar has a formed surface thereon for causing a rotor to rotate along at least a portion of the length thereof under the force of gravity.

Claim 10

The exerciser of claim 1 wherein said primary bar has a plurality of holes formed therein and equally radially spaced from the center thereof, each hole extending longitudinally along the length of said primary bar.

Claim 11

A variable weight exerciser comprising: a primary elongated bar; one or more substantially straight secondary elongated bars of lesser width than and substantially equal in length to said primary elongated bar, said primary bar being adapted to receive therein one or more of said secondary bars; and means for removably securing said secondary bars within said primary bar.

Claim 12

A variable weight exerciser comprising: a primary elongated bar; one or more substantially straight secondary elongated bars of lesser width than and substantially equal in length to said primary elongated bar, said primary bar being adapted to receive therein one or more of said secondary bars; and means for removably securing said secondary bars within said primary bar.

Claim 13

A variable weight exerciser comprising: a primary elongated bar; a second primary bar substantially equal in length to said primary bar and having a plurality of longitudinal grooves formed in the outer periphery thereof, said primary bar being adapted to receive said second primary bar therein and to form in conjunction with said second primary bar a plurality of longitudinal holes; one or more secondary elongated bars adapted for insertion into said longitudinal holes; and means for securing said secondary bars within said longitudinal holes.

Claim 14

A variable weight exerciser comprising: a primary elongated bar; a second primary bar substantially equal in length to said primary bar and having a plurality of longitudinal grooves formed in the outer periphery thereof, said primary bar being adapted to receive said second primary bar therein and to form in conjunction with said second primary bar a plurality of longitudinal holes; one or more secondary elongated bars adapted for insertion into said longitudinal holes; and means for securing said secondary bars within said longitudinal holes.
