Abstract
A system for supporting and carrying bicycles. The system cooperating with the interior surfaces of the seat post engagement tube and includes an adjustable post having a first end and a second end, the first end having an attachment mechanism adapted for connecting the post to a support surface. The second end having at least two generally parallel surface areas at an adjustable distance from one another, so that the distance between the generally parallel areas can be enlarged or reduced in a generally radial manner to create or maintain line contact with the interior surface of the seat post engagement tube.
Claims7
A system for supporting a bicycle frame from a support structure, the bicycle frame having a seat post tube having an aperture of a size, the aperture being adapted for accepting a seat post for supporting a bicycle seat from the bicycle frame, the system comprising:
- An adjustable post having a first end and a second end along an axis, the first end having an attachment mechanism adapted for attachment to the support surface structure;
- and
- The second end supporting at least two generally parallel surface areas at an adjustable distance from one another, said generally parallel surface areas are on an elastic sleeve having a first end and a second end, and a movable plate is mounted against the elastic sleeve, the movable late including a mechanism for moving the movable plate and compressing the elastic sleeve along the axis squeezing the first end of the elastic sleeve towards the second end of the elastic sleeve, causing the generally parallel surface areas to move away from one another, at least one of the generally parallel surface areas including at least two surface points along a line that is generally parallel to the axis, the generally parallel surface areas are radially moveable in a generally parallel fashion from the axis of the adjustable post, so that the distance between the generally parallel areas can be enlarged or reduced in a generally radial manner from the axis to create or maintain line contact with the interior surface of the seat post tube.
A system for supporting a bicycle frame from a vehicle, the bicycle frame having a seat post tube having an aperture of a size, the aperture being adapted for accepting a seat post for supporting a bicycle seat from the bicycle frame, the system comprising:
- a support structure comprising a beam, the beam having at least one end adapted for support from the vehicle, said beam further comprises a first end and a second end, the first end of said beam includes a generally square cross-section adapted for engagement with a generally square female portion of a receiver hitch;
- an adjustable post having a first end and a second end along an axis, the first end having an attachment mechanism adapted for attachment to the support surface structure;
- and the second end supporting at least two generally parallel surface areas at an adjustable distance from one another, at least one of the generally parallel surface areas including at least two surface points along a line that is radially moveable in a generally parallel fashion from the axis of the adjustable post, so that the distance between the generally parallel areas can be enlarged or reduced in a generally radial manner from the axis to create or maintain line contact with the interior surface of the seat post tube.
A method for supporting a bicycle frame from a support structure, the bicycle frame having a seat post tube having an aperture of a size and an interior portion, the aperture being adapted for accepting a seat post for supporting a bicycle seat from the bicycle frame, the method comprising:
- providing an adjustable post having a first end and a second end along an axis, the first end having an attachment mechanism adapted for attachment to the support structure, the second end supporting at least two generally parallel surface areas at an adjustable distance from one another, at least one of the generally parallel surface areas including at least two surface points along a line that is radially moveable in a generally parallel fashion from the axis of the adjustable post, so that the distance between the generally parallel areas can be enlarged or reduced in a generally radial manner from the axis to create or maintain line contact with the interior surface of the seat post tube;
- mounting said adjustable post on a support arm adapted for engagement with a female portion of a receiver hitch and using the two generally parallel surface areas to engage the interior surface of the seat post tube, so that the bicycle is supported solely by the adjustable post.
