Claims

[Claims for Utility Model Registration] (1) A remotely adjustable bicycle-type seat support column with dimensions adapted to be mounted in a generally upright position within the seat tube 38 of a bicycle or similar device. A mounting tube member 22 having a mounting tube member 22 having a mounting tube member 22 having an enlarged collar 36 at the upper end thereof for limiting the insertion position within the bicycle seat support column, and a seat support column 24 movable in the axial direction, a support column that is telescopically adjustable to different levels within the mounting tube member and adapted to support a saddle or seat at its upper end; a main spring 26 for upward movement relative to the mounting tube member; a toothed rack surface 62 extending longitudinally along said seat support post; a floating gear 96, a floating latch 98, a toggle lever 100 and a supplementary spring. 102, wherein the floating gear is loosely disposed within a first recess 90 in the collar and is moved to a locking position in which it engages the toothed rack surface. the floating catch member 98 is disposed within a recess in the collar loosely outwardly of the gear and is adapted to move with the gear, and is opposed to the rack surface. the toggle lever 100 having teeth for engaging the gear, the toggle lever 100 being pivotally mounted in a second recess 95 intersecting the first recess in the collar, and having respective latching members and remotely adjustable, having a portion for engaging the coupling cable 30, wherein the complementary spring 102 is coupled between the toggle lever and the collar and adapted to bias the gear into the locked position. A bicycle-type seat support column that can be used. (2) Handle release device 134 positioned away from the mounting tube member and seat support column.
and a release device constructed and arranged to engage the coupling cable and permit the rider to move the toggle lever against the biasing force of the supplementary spring when using said bicycle or similar device. 2. A remotely adjustable bicycle seat support column as claimed in claim 1. 3. The remotely adjustable system of claim 1, further comprising: a handle release device (134) located remotely from the mounting tube member and seat support post; and a device (30) for moving the toggle lever in response to actuation of the handle release device. A bicycle-type seat support column that can be used. 4. The remotely adjustable bicycle seat support column of claim 3, wherein the device for moving the toggle lever in response to actuation of the handle release device is a cable device. (5) the floating latch member 98 and the gear 96 are located in the recess 90 of the collar, a groove intersects the recess, and the toggle lever 100 is freely guided into the groove; 2. The remotely adjustable bicycle seat support post of claim 1, wherein the remotely adjustable bicycle seat support post is mounted and adapted to engage the catch member. (6) Said floating gear 96 has a central axis 106 in said groove 95 to guide and move said gear floatingly into its locking position in engagement with the toothed rack surface 62 of the seat support column; 6. The remotely adjustable bicycle seat support column of claim 5, wherein said remotely adjustable bicycle seat support post is adapted to be moved away from said position. (7) further comprising an auxiliary spring device 104 biasing the gear wheel away from the locked position, the supplementary spring device 102 being relatively stronger than and adapted to overcome the auxiliary spring device; A remotely adjustable bicycle seat support column according to item 1. (8) A remotely adjustable bicycle seat support column extending along a central axis and dimensioned to be mounted in a generally upright position within the seat tube 38 of a bicycle 40 or similar device. a mounting tube member having an enlarged collar 36 at its upper end for limiting its insertion position within the bicycle seat support column; and a seat support column 24 movable in the axial direction; a seat support column that is telescopically adjustable to different levels within the mounting tube member and adapted to support a saddle or seat at its upper end; A locking device 28 having a main spring 26 driven upwardly against the tubular member, a toothed rack surface 62 extending longitudinally along the seat support post, a loosely floating toothed member, a toggle lever and a supplementary spring. and a locking device contained within a collar within the recess device comprising first, second and third interconnected recesses, the first recess 90 being a floating toothed member 98a is loosely guided within the first recess extending through the collar from an open outer end to an open inner end communicating with the seat support post along a line extending substantially radially relative to the central axis; the second recess 95 has an outwardly open groove intersecting the first recess; , a second recess is defined between the side walls extending transversely to the central axis, the toggle lever 1
00a is pivotally mounted in the second recess and has opposite portions for engaging the floating toothed member and the coupling cable to the remote release cable, respectively, and the third recess 120 is pivotally mounted in the second recess. a complementary spring 102 is disposed within the third recess and is coupled between the toggle lever and the collar to bias the toothed member toward the locked position; Remotely adjustable bicycle-style seat support. 9.
