Abstract
An apparatus for attaching a seat to a seat post comprises a cylindrical housing with oppositely oriented openings on the side of the housing. Top and bottom clamping pieces are positioned through the openings. Mating grooves on the ends of the clamps are adapted for placement and securing of a pair of rails affixed to the underside of the seat. A bottom block is disposed beneath the clamps and adapted for abutment against the clamps. The interior bottom portion of the housing is threaded, and the exterior top portion of the seat post is threaded for engagement with the threads of the housing, so that the seat post itself is tightened against the bottom piece, thus securing the seat rails within the clamps without need for tools or small components.

Seat attachment apparatus, adapted for use with a seat including an attachment member, comprising:
- a housing;
- an elongate seat post having first and second ends, the first end being engaged with and adapted for rotational movement within the housing;
- means for moving the seat post through the housing in a direction into or out of the housing when the seat post is rotated relative to the housing;
- a clamp assembly, adapted for selective engagement of the attachment member, disposed within the housing;
- and
- a connector selectively connecting the seat post to the clamp assembly such that the movement of the seat post relative to the housing causes the clamp assembly selectively to engage and disengage the attachment member.
Seat attachment apparatus, the seat having an attachment member, comprising:
- a housing including a first arm and a second arm oriented adjacent each other, each arm having a proximal end and a distal end, the arms being joined at their proximal ends, each arm having an interior surface disposed adjacent the interior surface of the other arm and an exterior surface disposed substantially opposite the interior surface;
- a clamp assembly for selective engagement of the attachment member disposed between the arms;
- an elongate seat post with first and second ends, the first end extending through the arms at a location between the clamp assembly and the distal ends of the arms, the seat post being adapted for rotational movement within and relative to the arms;
- and
- urging means, operatively connecting the seat post and the arms, for selectively urging the arms together when the seat post is rotated relative to the arms in a first direction and ceasing to urge the arms together when the seat post is rotated relative to the arms in a second direction.
Apparatus for attachment to a seat, the seat having an attachment member, comprising:
- an elongate seat post having a first end and a second end;
- an opposer having a head and a body, the body being rotatably attached to the seat post and the head being spaced from the first end of the seat post;
- means for decreasing the distance between the first end of the seat post and the head of the opposer when the opposer is rotated relative to the seat post in a first direction, and for increasing the distance between the first end of the seat post and the head of the opposer when the opposer is rotated relative to the seat post in a second direction;
- a clamp assembly, for selective engagement of the attachment member, disposed substantially between the first end of the seat post and the head of the opposer, the clamp assembly being disposed such that rotation of the clamp assembly relative to the seat post in said first direction rotates the opposer in said first direction and rotation of the clamp assembly relative to the seat post in said second direction rotates the opposer in said second direction;
- whereby the clamp assembly is tightened when the opposer is rotated relative to the seat post in said first direction and loosened when the opposer is rotated relative to the seat post in said second direction.
Seat attachment apparatus for use with a bicycle frame, the seat including an attachment member, comprising:
- a seat post comprising first and second arms, each arm having distal and proximal ends, the arms being joined at their proximal ends and defining a cavity near their proximal ends when in a closed position, the seat post being nestable in the frame of the bicycle;
- clamp assembly, for selective engagement of the attachment member, disposed within said cavity;
- holding means for selectively locking the arms in said closed position, the holding means being disposed between the frame of the bicycle and the clamp assembly.
Seat attachment apparatus for use with a bicycle frame, the seat including an attachment member, comprising:
- a seat post comprising first and second arms, each arm having distal and proximal ends, the arms being joined at their proximal ends and defining a cavity near their proximal ends when in a closed position, the seat post being nestable in the frame of the bicycle;
- clamp assembly, for selective engagement of the attachment member, disposed
- holding means for selectively locking the arms in said closed position, the ted.
Seat attachment apparatus, adapted for use with a seat including an attachment member, comprising;
- a clamp assembly, adapted for selective engagement of the attachment member,
- an elongate seat post having first and second ends, the first end being disposed adjacent the clamp assembly, and
- pivotal clip means for selectively securing the clamp assembly adjacent to the elongate seat post so as to hold the seat in a fixed position.
Seat attachment apparatus, adapted for use with a seat including an attachment member, the apparatus comprising:
- moveable clamp means for selectively holding the attachment member of the seat so as to hold the seat in a set position;
- housing means disposed at least partially about the movable clamp means and having an interior portion for holding the clamp means such that selectively forcing the clamp means into contact with the interior portion of the housing prevents the clamp means from moving;
- and
- rotatable adjustment means for selectively forcing the movable clamp into contact with an interior portion of the housing so as to prevent movement of the clamp, said rotatable adjustment means comprising a seat post.
Seat attachment apparatus for attaching a seat to a seat post, adapted for use with a seat including an attachment member, the apparatus comprising:
- moveable clamp means disposed adjacent the seat post for selectively holding the attachment member of the seat so as to hold the seat in a set position;
- housing means disposed at least partially about the movable clamp means and having an interior portion for holding the clamp means such that selectively forcing the clamp means into contact with the interior portion of the housing prevents the clamp means from moving;
- and
- rotatable adjustment means for selectively forcing the movable clamp into contact with an interior portion of the housing so as to prevent movement of the clamp, the adjustment means comprising a collar rotatable about the seat post.
