Adjustable weight exercise methods and apparatus
View Patent ↗An exercise dumbbell system includes a handle and weight plates maintained in spaced relationship at opposite ends thereof. Weight selectors are movable laterally into and out of engagement with respective weight plates to secure them relative to the handle. Each weight plate is provided with a pathway having at least one notch that opens upward, and at least one groove that is bounded above by a lip. The selectors have respective weight engaging portions that travel along respective pathways to alternatively underlie different combinations of the weights.
1. A method of adjusting resistance to exercise, comprising the steps of:
providing a lifting member having at least one weight holder;
providing weights sized and configured to be supported by the at least one weight holder, and to define respective selector paths having portions that are upwardly open and portions that are upwardly closed;
providing a weight selector having weight supports that are sized and configured to travel along respective selector paths; and
movably mounting the weight selector on the lifting member for movement along the selector paths.
2. The method of claim 1 , further comprising the step of providing indicia on upwardly facing portions of the lifting member to alternatively align with the weight selector and indicate how much force is required to lift the lifting member as a function of how many of the weights are currently connected thereto by the weight selector.
3. The method of claim 1 , further comprising the step of maintaining the weights in a horizontal array when disengaged from the lifting member.
4. The method of claim 3 , further comprising the steps of resting the lifting member on the weights, and selectively moving the weight selector across the tops of the weights to engage a desired combination of the weights.
5. A method of adjusting resistance to exercise, comprising the steps of:
providing a lifting member having at least one weight holder, and a weight selector having weight engaging members;
providing weights sized and configured to be supported by the at least one weight holder and engaged by respective weight engaging members;
positioning the lifting member relative to the weights so that the weight engaging members are disposed adjacent respective weights;
moving the weight selector in a direction parallel to an interface defined between adjacent weights to lock a first one of the weights relative to the lifting member; and
further moving the weight selector in said direction to lock a second one of the weights relative to the lifting member.
6. The method of claim 5 , further comprising the step of providing indicia on upwardly facing portions of the lifting member to alternatively align with the weight selector and indicate how much force is required to lift the lifting member as a function of how many of the weights are currently connected thereto by the weight selector.
7. The method of claim 5 , further comprising the step of maintaining the weights in a horizontal array when disengaged from the lifting member.
8. The method of claim 5 , further comprising the step of moving the weight selector still further in said direction to unlock the second one of the weights relative to the lifting member.
9. A method of adjusting resistance to exercise, comprising the steps of:
providing a handle that defines a longitudinal axis;
securing weight holders to opposite ends of the handle;
providing weights sized and configured to be supported by the weight holders, and to define respective selector paths having portions that are upwardly open and portions that are upwardly closed;
providing a weight selector having weight supports that are sized and configured to travel along respective selector paths; and
movably mounting the weight selector on at least one of the weight holders for movement along the selector paths.
10. The method of claim 9 , further comprising the step of providing indicia on upwardly facing portions of said at least one the weights holders to alternatively align with the weight selector and indicate how much force is required to lift the lifting member as a function of how many of the weights are currently connected thereto by the weight selector.
11. The method of claim 9 , further comprising the step of maintaining the weights in a horizontal array when disengaged from the lifting member.
12. The method of claim 11 , further comprising the steps of resting the weight holders on the weights, and selectively moving the weight selector across the tops of the weights to engage a desired combination of the weights.
13. A method of adjusting resistance to exercise, comprising the steps of:
providing a handle assembly with a handle that defines a longitudinal axis, weight holders at opposite ends of the handle, and a weight selector having weight engaging members;
providing weights sized and configured to be supported by the weight holders and engaged by the weight engaging members;
positioning the handle assembly relative to the weights so that the weight engaging members are disposed adjacent respective weights;
moving the weight selector laterally relative to the axis to lock a first one of the weights relative to the handle assembly; and
further moving the weight selector laterally relative to the axis to lock a second one of the weights relative to the handle assembly.
14. The method of claim 13 , further comprising the step of providing indicia on upwardly facing portions of the handle assembly to alternatively align with the weight selector and indicate how much force is required to lift the lifting member as a function of how many of the weights are currently connected thereto by the weight selector.
15. The method of claim 13 , further comprising the step of maintaining the weights in a horizontal array when disengaged from the lifting member.
16. The method of claim 13 , further comprising the step of moving the weight selector still further laterally to unlock the second one of the weights relative to the handle assembly.
