Abstract
A bicycle including a frame having a main frame portion and an articulating frame portion pivotally mounted to the main frame portion and carrying a rear wheel of the bicycle at a hub axis. A shock absorber is operably connected between the main frame portion and the articulating frame portion to provide resistance to articulating motion of the articulating frame portion. A rearward end of the shock absorber preferably is pivotally mounted to the articulating frame portion at a location near the hub axis. The shock absorber preferably is positioned within a perimeter defined in a vertical plane generally by the articulating frame portion.
Claims25
A bicycle frame, comprising:
- a main frame portion;
- an articulating frame portion comprising:
- a pair of lower arms having a forward end and a rearward end, said forward ends being pivotally connected to said main frame portion at a first pivot axis;
- a pair of upper arms having a lower end and an upper end, said lower ends being pivotally connected near said rearward ends of said lower arms at a second pivot axis, one of said rearward ends of said lower arms and said lower ends of said upper arms defining a hub axis;
- a link pivotally connected to said upper ends of said upper arms at a third pivot axis and pivotally connected to said main frame portion at a fourth pivot axis;
- and
- a shock absorber pivotally connected to one of said main frame portion and said link at a fifth pivot axis and pivotally connected to said articulating frame portion at a sixth pivot axis, said sixth pivot axis being located near said hub axis.
A bicycle frame, comprising:
- a main frame portion comprising a top tube, a seat tube and a down tube arranged in a generally triangular arrangement defining a generally triangular space therebetween, a first water bottle mount defined on said seat tube and facing said space, said first mount sized and shaped to permit a first water bottle holder to be secured to said seat tube at said first mount and a second water bottle mount defined on said down tube and facing said space, said second mount sized and shaped to permit a second water bottle holder to be secured to said down tube at said second mount;
- an articulating frame portion comprising a pair of lower arms having a forward end and a rearward end, a pair of upper arms having a lower end and an upper end, and a link, said forward ends of said lower arms being pivotally connected to said main frame, said lower ends of said upper arms being pivotally connected near said rearward ends of said lower arms, said link being pivotally connected to said upper ends of said upper arms at a first end and pivotally connected to said main frame, a hub axis defined by one of said lower ends of said upper arms and said rearward ends of said lower arms;
- and
- a shock absorber pivotally connected to one of said main frame and said link at a first end and pivotally connected to said articulating frame portion near said hub axis at a second end.
A bicycle frame, comprising:
- a main frame portion comprising a seat tube;
- an upper mounting bracket connected to said seat tube;
- a lower mounting bracket connected to said main frame;
- an articulating frame portion comprising:
- a pair of lower arms having a forward end and a rearward end, said forward ends being pivotally connected to said lower mounting bracket;
- a pair of upper arms having a lower end and an upper end, said lower ends being pivotally connected near said rearward ends of said lower arms, one of said rearward ends of said lower arms and said lower ends of said upper arms defining a hub axis;
- a link pivotally connected to said upper ends of said upper arms and pivotally connected to said upper mounting bracket;
- and
- a shock absorber pivotally connected to one of said main frame portion and said link at a first end and pivotally connected to said articulating frame portion near said hub axis at a second end.
A bicycle frame, comprising:
- a main frame portion;
- an articulating frame portion comprising:
- a pair of lower arms having a forward end and a rearward end, said forward ends being pivotally connected to said main frame portion;
- a pair of upper arms having a lower end and an upper end, said lower ends being pivotally connected near said rearward ends of said lower arms, one of said rearward ends of said lower arms and said lower ends of said upper arms defining a hub axis;
- a link pivotally connected to said upper ends of said upper arms and pivotally connected to said main frame portion;
- and
- a shock absorber connected to said bicycle frame and being arranged to provide a force resisting movement of said articulating frame portion with respect to said main frame portion, a first end of said shock absorber being pivotally connected to said articulating frame portion near said hub axis.
