Abstract
The selector rod has a dedicated engagement member for each of a plurality of aligned weight plates. Each engagement member is rigidly affixed to the selector rod at a discrete location along the longitudinal axis of the selector rod, and each engagement member extends radially outward from the selector rod.
Claims27
A weight selector assembly in combination with a plurality of aligned weight plates, comprising:
- a base member;
- and
- a rotatable selector rod rotatably mounted on said base member, wherein said selector rod includes a shaft having a longitudinal axis, and a dedicated engagement member for each of the weight plates, wherein each said engagement member is rigidly affixed to said shaft at a discrete axial location, and each said engagement member extends radially outward from said shaft.
A weight plate selector rod, comprising:
- a shaft having a longitudinal axis;
- and
- at least three weight plate engagement members rigidly affixed to said shaft at discrete, axially spaced locations along said shaft, wherein at least two said engagement members occupy respective, dissimilar sectors relative to said axis, and said sectors at least partially occupy a common quadrant of space associated with said longitudinal axis.
A weight plate selector rod, comprising:
- a shaft having a longitudinal axis;
- and
- at least three weight plate engagement members rigidly affixed to said shaft at discrete, axially spaced locations along said shaft, wherein each of said engagement members has an axial profile as viewed from an axial perspective, and at least two of said engagement members are both axially spaced apart from one another and at least partially visible from said axial perspective.
A weight plate selector rod, comprising:
- a shaft having a longitudinal axis;
- and
- at least three weight plate engagement members rigidly affixed to said shaft at discrete, axially spaced locations along said shaft, wherein at least a portion of a first one of said engagement members is circumferentially displaced relative to at least a portion of a second one of said engagement members, and at least a portion of a third one of said engagement members is circumferentially displaced relative to both at least a portion of said first one of said engagement members and at least a portion of said second one of said engagement members.
A weight plate selector rod, comprising:
- a shaft having a longitudinal axis;
- and
- at least three weight plate engagement members rigidly affixed to said shaft at discrete, axially spaced locations along said shaft, wherein each of said weight plate engagement members includes a first portion which extends perpendicularly away from said shaft, and a second portion which protrudes perpendicularly away from said first portion at a distance apart from said shaft, and which terminates in a distal end, whereby a gap is defined between said second portion and said shaft.
