Abstract
A device for supporting a saddle of a bicycle, a mountain bike, etc., which includes a support frame, a guide tube secured to the support frame, and a tubular support member upwardly biased by a spring means. The projecting end portion of the tubular support member is connected to a mounting member for the saddle so that the support member and the saddle mounting member are movable relative to each other in a direction transverse to the longitudinal axis of the support member. The saddle mounting member is swingably connected to the guide tube.
Claims11
A device for supporting a saddle on a support frame post of a support frame of a vehicle, comprising:
- a guide tube adapted to be inserted in and secured to the support frame post so that one end of said guide tube extends from the support frame post;
- a tubular support member mounted for axial sliding movement in said guide tube;
- a spring arrangement resiliently supporting said tubular support member in said guide tube so that one end of said tubular support member extends from said guide tube;
- a saddle mounting member connected to said one end of said tubular support member by a connection permitting a limited amount of relative movement between said saddle mounting member and said tubular support member in a longitudinal direction transverse to the axis of said tubular support member;
- a bearing arm integral with said one end of said guide tube and extending in the longitudinal direction;
- and
- two parallel links, each said parallel link having opposite ends pivotally connected at points of pivotal connection to a forward portion of said bearing arm and said saddle mounting member, respectively, wherein a line connecting the points of pivotal connection between said two parallel links and the forward portion of said bearing arm and a line connecting the points of pivotal connection between said two parallel links and said saddle mounting member are generally parallel with the axis of said tubular support member so as to form a parallelogram link mechanism.
