Abstract
A bicycle seat adjustable device includes an outer tube and an inner tube inserted into the outer tube. A piston seat and a clamp unit are connected to the inner tube. A valve unit extends through the piston seat and is located in the inner tube. The valve unit includes a rod extending through the piston seat and reaches the bottom end of the outer tube. A control unit has a control unit connected to the bottom end of the outer tube and an action unit is located outside of the outer tube. The control unit has a push member connected with the rod. The action unit has a cable extending through the outer tube and connected to the push member. A switch is connected to the cable. The push member is indirectly moved to move the rod to control the hydraulic path in the piston seat by pulling the cable.

A bicycle seat adjustment device comprising:
- an outer tube (10) having a top end (11) and a bottom end (12);
- an inner tube (20) inserted into the outer tube (10) via the top end (11) of the outer tube (10), the inner tube (20) having a piston seat (21) and a clamp unit (22) on two ends thereof;
- a valve unit (30) extending through the piston seat (21) and located in the inner tube (20), the valve unit (30) comprising a rod (31) extending through the piston seat (21) and reaching the bottom end (12), the rod displaceably engaging to alternatively seal and unseal a flow path through the piston seat (21), and
- a control assembly (40) having a control unit (41) connected to the bottom end (12) of the outer tube (10) and an action unit (42) located outside of the outer tube (10), the control unit (41) having a push member (411) engaging the rod (31) to move the rod (31) linearly, the action unit (42) remotely controlling the push member by a cable (421) extending along a sidewall of the outer tube (10) to the bottom end thereof, a distal end of the cable (421) connected to a switch (422), the push member (411) being remotely actuated responsive to the switch to move the rod (31) for selectively controlling the flow path through the piston seat (21) to alternatively release and lock the bicycle seat in adjusted position.
A bicycle seat adjustment device comprising:
- an outer tube (10) having a top end (11) and a bottom end (12);
- an inner tube (20) inserted into the outer tube (10) via the top end (11) of the outer tube (10), the inner tube (20) having a piston seat (21) and a clamp unit (22) on two ends thereof;
- a valve unit (30) extending through the piston seat (21) and located in the inner tube (20), the valve unit (30) comprising a rod (31) extending through the piston seat (21) and reaching the bottom end (12), the rod displaceably engaging to alternatively seal and unseal a flow path through the piston seat (21), and
- a control assembly (40) having a control unit (41) connected to the bottom end (12) of the outer tube (10) and an action unit (42) located outside of the outer tube (10), the control unit (41) having a push member (411) engaging the rod (31) to move the rod (31) linearly, the action unit (42) remotely controlling the push member by an oil hose (429) extending along a sidewall of the outer tube (10) to the bottom end thereof, a distal end of the oil hose (429 connected to a switch (422), the push member (411) being remotely actuated responsive to the switch to move the rod (31) for selectively controlling the flow path through the piston seat (21) to alternatively release and lock the bicycle seat in adjusted position.
