Patent ID: 6942290

Claim:
A mounting arrangement for mounting on a stationary bicycle chassis a variety of seats each having a pair of parallel frame members, comprising: a base member having a clamp operatively interconnecting said base member and the bicycle chassis; a horizontally disposed seat-receiving platform supported on the base member; the platform having on a top surface a pair of front and a pair of rear upstanding projection members for receiving the pair of parallel frame members to properly align and secure the seat on the platform; at least two of the projection members including detents for retaining releasably the pair of parallel frame members within the projection members; the platform further having a pair of parallel channels formed on the upper surface thereof and extending between the front and rear projection members, said channels adapted for receiving the pair of parallel frame members; an elongated lock block having a pair of latching curved recesses at opposite, distal ends thereof and rotatably mounted on the platform, said lock block being movable between a first position wherein the seat can be readily removed from the platform to enable another seat to be secured quickly in place, and a second position wherein the pair of latching curved recesses secure intermediate portions of the pair of parallel frame members; the lock block having a length less than the distance between the pair of front and the pair of rear projecting members; a rotatably mounted lock lever for enabling the lock block to be rotated; front and rear post members pivotally supporting the platform above the base member at opposite ends thereof, the upper ends of the post members being pivotally attached to the platform to enable the platform to tilt laterally from side to side when the seat is being used; a pair of compression springs flanking the rear post member to bias resiliently the platform into a generally parallel disposition relative to the base member, each spring extending between the platform and the base member.
