Abstract

Weight supporting members are rotated into engagement with respective weight plates to provide adjustable resistance to exercise movement. On a first embodiment, the weight supports are rigidly mounted on a selector rod and rotate together therewith. On a second embodiment, the weight supports are rotatably mounted on the selector rod and rotate relative thereto.

Claims

1. A method of providing adjustable resistance to exercise, comprising the steps of:

providing a rod having a longitudinal axis;

providing weight supporting members on the rod at axially spaced positions along the rod;

providing a plurality of aligned weights with openings sized and configured to accommodate the rod, and gaps disposed between adjacent weights to accommodate respective members;

moving the rod downward into the openings in a manner which aligns each of the members with a respective one of the gaps;

rotating the members relative to the weights until respective members underlie desired ones of the weights;

separately latching each of the members in a desired orientation; and

moving the rod upward together with the desired ones of the weights.

2. The method of claim 1, wherein each of the weight supporting members is independently rotated relative to the rod.

3. The method of claim 1, wherein the rod is provided with an intermediate portion that is sized and configured for grasping, and the weight supporting members are provided at opposite ends of the intermediate portion.

4. A method of providing adjustable resistance to exercise, comprising the steps of:

providing a rod having a longitudinal axis;

providing weight supporting members on the rod at axially spaced positions along the rod;

providing a plurality of aligned weights with openings sized and configured to accommodate the rod, and gaps disposed between adjacent weights to accommodate respective members;

moving the rod downward into the openings in a manner that aligns each of the members with a respective one of the gaps, wherein the rod is held in a horizontal orientation as the rod is moved downward into the openings;

rotating the members relative to the weights until respective members underlie desired ones of the weights; and

moving the rod upward together with the desired ones of the weights, wherein the rod is held in a horizontal orientation as the rod is moved upward out of the openings.

5. The method of claim 4, wherein each of the weight supporting members is independently rotated relative to the rod.

6. The method of claim 4, wherein each of the weight supporting members is independently latched relative to the rod.

7. A method of providing adjustable resistance to exercise, comprising the steps of:

providing a first set of weights and a second set of weights;

providing a base sized and configured to support each set of weights at a respective end of the base;

providing a handle member having an intermediate portion that is sized and configured for grasping, a first end portion that is sized and configured to support the first set of weights, and an opposite, second end portion that is sized and configured to support the second set of weights;

providing a plurality of separately rotatable weight selectors on each said end portion, wherein each of the weight selectors is configured and arranged to selectively engage and disengage a respective one of the weights as a function of orientation relative thereto;

moving the handle member to a rest position relative to the weights and the base;

rotating a first subset of the weight selectors to a first orientation relative to the handle member to engage respective weights; and

rotating a second subset of the weight selectors to a second orientation relative to the handle member to disengage respective weights, wherein each said rotating step rotates a respective said subset of the weight selectors relative to the other said subset of the weight selectors.

8. The method of claim 7, further comprising the step of latching each of the weight selectors in one of the first orientation and the second orientation.

9. The method of claim 7, wherein the handle member is provided with a rod that spans the intermediate portion and each said end portion, and the weights are provided with respective, upwardly opening slots to receive respective portions of the rod, and the moving step involves inserting the respective portions of the rod into the respective, upwardly opening slots.

10. A method of providing adjustable resistance to exercise, comprising the steps of:

providing a first set of weights and a second set of weights;

providing a base sized and configured to support each set of weights at a respective end of the base;

providing a handle member having an intermediate portion that is sized and configured for grasping, a first end portion that is sized and configured to support the first set of weights, and an opposite, second end portion that is sized and configured to support the second set of weights;

providing weight selectors on each said end portion, wherein each of the weight selectors is provided with a leaf spring portion, and is configured and arranged to selectively engage and disengage a respective one of the weights as a function of orientation relative thereto;

moving the handle member to a rest position relative to the weights and the base;

rotating desired weight selectors to a first orientation relative to the handle member to engage respective weights;

rotating desired weight selectors to a second orientation relative to the handle member to disengage respective weights, wherein each said rotating; and

latching each of the weight selectors in one of the first orientation and the second orientation by moving the leaf spring portion into a respective notch at a respective end of the handle member.

11. The method of claim 10, wherein each portion is configured as a weight housing having a top wall, and each said leaf spring portion is configured and arranged to extend through a respective slot in the top wall, and each said notch is formed in the top wall at a respective end of a respective slot, and the rotating step involves deflecting the leaf spring portion out of a first notch in a direction perpendicular to the slot to align with the slot, then moving the leaf spring portion along the slot, and then allowing the leaf spring portion to deflect into a second notch at an opposite end of the slot.

12. The method of claim 10, wherein each of the weight selectors is provided with a discontinuous, circumferential lip, and the rotating step involves rotation of the lip into and out of an underlying position relative to a protrusion on a respective one of the weights.

13. A method of providing adjustable resistance to exercise, comprising the steps of:

providing a first set of weights and a second set of weights;

providing a base sized and configured to support each set of weights at a respective end of the base;

providing a handle member having an intermediate portion that defines a longitudinal axis and is sized and configured for grasping, a first weight housing disposed at a first end of the handle member and sized and configured to support the first set of weights, and a second weight housing disposed at an opposite, second end of the handle member and sized and configured to support the second set of weights;

providing multiple weight selectors at longitudinally spaced locations on each said weight housing with first portions that are configured and arranged to protrude through respective, longitudinally spaced slots in a respective weight housing, and second portions that are selectively movable into engagement and disengagement relative to respective weights;

lowering the handle member into a rest position relative to the weights and the base; and

moving desired weight selectors relative to the handle member to adjust which weights are connected to the handle member and which weights are disconnected from the handle member.

14. The method of claim 13, wherein each said weight housing is provided with a top wall, and said slots extend across respective first portions between first ends of respective slots and second ends of respective slots.

15. The method of claim 14, wherein each said weight housing is provided with notches at respective ends of respective slots, and the moving step involves deflecting respective first portions out of respective first notches in a direction perpendicular to the slots to align with the slots, then moving the first portions along respective slots, and then allowing the first portions to deflect into respective second notches at opposite ends of respective slots.
