Abstract

A weight lifting device includes a handle having two end segments, a number of weight members each having a slot to receive either of the end segments of the handle, and an anchor plate rotatably attached to each of the weight members and having an opening selectively aligned with the slot of the weight member, to selectively receive either of the end segments of the handle. The anchor plate is rotatable relative to the weight member to offset the opening of the anchor plate from the slot of the weight member, and to selectively anchor the weight member to the handle. The desired number of weight members may thus be selectively attached to the handle.

Claims

1. A weight lifting device comprising:

a handle including two end segments,

a weight member including a center hold formed therein, and including a slot formed therein and extended from said center hole thereof to a perimeter of said weight member, for receiving either of said end segments of said handle, and

an anchor plate rotatably attached to said weight member, and including a center hole formed therein, and including an opening formed therein, said opening extended from said center hole thereof to a perimeter of said anchor plate such that said center hole and said opening of said anchor plate form a continuous and uninterrupted aperture, and selectively aligned with said slot of said weight member to selectively receive either of said end segments of said handle, and

said anchor plate being rotatable relative to said weight member to offset said opening of said anchor plate from said slot of said weight member, and to selectively anchor said weight member to said handle, and

wherein said weight member includes at least one peg attached thereto, said anchor plate includes at least one enclosed curved channel formed therein to slidably receive said at least one peg of said weight member and to rotatably attach said anchor plate to said weight member.

2. The weight lifting device as claimed in claim 1, wherein said at least one peg of said weight member includes an enlarged head provided thereon, to engage with said anchor plate, and to retain said anchor plate to said weight member, and to prevent said anchor plate from being disengaged from said weight member.

3. The weight lifting device as claimed in claim 1, wherein said weight member includes a spring biased projection received therein, and engageable with said anchor plate, to maintain said opening of said anchor plate in alignment with said slot of said weight member.

4. The weight lifting device as claimed in claim 3, wherein said anchor plate includes a cavity formed therein, to selectively receive said spring biased projection of said weight member.

5. The weight lifting device as claimed in claim 1, wherein said weight member includes a spring biased projection received therein, and engageable with said anchor plate, to maintain said opening of said anchor plate in offset from said slot of said weight member.

6. The weight lifting device as claimed in claim 1, wherein either of said end segments of said handle includes at least one notch formed therein, and defined between protuberances, to receive said anchor plate and said weight member.

7. The weight lifting device as claimed in claim 1, wherein said anchor plate includes a hand grip extended therefrom, for rotating said anchor plate relative to said weight member.

8. The weight lifting device as claimed in claim 1 further comprising a base having a plurality of depressions formed therein for receiving said weight member.

9. The weight lifting device as claimed in claim 8, wherein said weight member includes an indentation formed therein, and said base includes a projection extended into each of said depressions thereof, and engageable into said indentation of said weight member, to anchor said weight member to said base.
