Adjustable height shock absorbing bicycle seat mounting assembly

A shock absorbing and adjustable height bicycle seat mounting assembly for installation onto a bicycle frame hollow vertical seat support member for supporting a bicycle seat thereon, said mounting assembly comprising:

• a seat supporting guide tube movably supported within bushing means with said guide tube and said bushing means mutually configured for axial sliding but non-rotational movement of said guide tube within said bushing means,
• said guide tube containing a longitudinally extending internal bore and having a top end adapted for mounting a bicycle seat thereon,
• said bushing means being adapted for affixment to a top portion of the bicycle frame vertical seat support member with said supported guide tube vertically depending therefrom interiorly of the bicycle frame hollow vertical seat support member,
• a gas spring, having an actuator and a piston rod along which said gas spring is operable for length adjusting axial movement in length adjusting and length locking modes upon operation of said actuator, adapted to be contained within the interior of a lower portion of the bicycle frame vertical seat support member for sliding axial movement therewithin with a lower end of said gas spring piston rod affixed to the bicycle frame vertical support member lower portion and an upper portion of said gas spring engaging a lower end of said vertically depending guide tube,
• a push rod slidably contained within said guide tube bore for axial sliding movement therewithin between an upper position removed from operable contact with said gas spring actuator and a lower position in operable contact with said gas spring actuator and
• means connected to said push rod for moving said push rod longitudinally of said guide tube bore between said upper and lower positions.

A shock absorbing and adjustable height bicycle seat mounting assembly for installation within a bicycle frame vertical seat support member having a hollow interior for supporting a bicycle seat thereon, said mounting assembly comprising:

• a seat supporting guide tube movably supported within bushing means with said guide tube and said bushing means mutually configured for axial sliding but non-rotational movement of said guide tube within said bushing means,
• said guide tube containing a longitudinally extending internal bore and having a top end adapted for mounting a bicycle seat thereon,
• said bushing means being adapted for fixed containment within a top interior portion of the bicycle frame vertical seat support member with said guide tube contained in said bushing means vertically depending therefrom within the hollow interior of the bicycle frame vertical seat support member,
• a gas spring, having an actuator and a piston rod along which said gas spring is operable for length adjusting axial movement in length adjusting and length locking modes upon operation of said actuator, adapted to be contained within the interior of a lower portion of the bicycle frame vertical seat support member for sliding axial movement therewithin with a lower end of said gas spring piston rod affixed to the bicycle frame vertical support member lower portion and an upper portion of said gas spring engaging a lower end of said vertically depending guide tube,
• a push rod slidably contained within said guide tube bore for axial sliding movement therewithin between an upper position removed from operable contact with said gas spring actuator and a lower position in operable contact with said gas spring actuator and
• means connected to said push rod for moving said push rod longitudinally of said guide tube bore between said upper and lower positions.

In a bicycle having a shock absorbing and adjustable height bicycle seat mounting assembly supported on a hollow vertical member of the bicycle frame wherein said mounting assembly comprises:

• bushing means affixed to a top portion of said bicycle frame vertical member,
• a seat supporting cylindrical guide tube movably contained within said bushing means with said guide tube and said bushing means mutually configured for axial sliding but non-rotational movement of said guide tube within said bushing means and from which said guide tube vertically depends interiorly of said hollow bicycle frame vertical member,
• said guide tube containing a longitudinally extending internal bore,
• means for mounting a bicycle seat on a top end of said guide tube,
• a gas spring, having an actuator and a piston rod along which said gas spring is operable for length adjusting axial movement in length adjusting and length locking modes upon operation of said actuator, movably contained within a lower portion of said bicycle frame vertical member for sliding axial movement therewithin with a lower end of said gas spring piston rod affixed to said bicycle frame vertical member lower portion and an upper portion of said gas spring engaging a lower end of said vertically depending guide tube,
• a push rod slidably contained within said guide tube bore for axial sliding movement therewithin between an upper position removed from operable contact with said gas spring actuator and a lower position in operable contact with said gas spring actuator and
• means connected to said push rod actuatable by a bicycle rider for moving said push rod longitudinally of said guide tube bore between said upper and lower positions.
