The bores into which the locking pin engages, are located in the region of the smallest stress of the saddle support tube in order to weaken the static of the saddle support tube as little as possible. ## Claims ### Claim 1 A height adjustable saddle pole consisting of two tubes which are telescopically slidable into another, that is to say 1.1. a cladding tube for accommodating a saddle support tube 1.2. a spring element acting upon the saddle support tube, 1.3. a locking device, which is arranged on the cladding tube with 1.3.1. a locking pin 1.3.2. a guide for the locking pin 1.3.3. means for adjusting the locking pin in a latched position and an unlatched position, whereas the locking pin is moved orthogonally with respect to and in the direction of the axis of the saddle support tube 1.4. whereas at least two axially spaced apart bores are provided in the saddle support tube for accommodating the locking pin, wherein 1.5. the locking pin in the latched position engages into one of the bores through a recess of the cladding tube, whereas it completely absorbs the axial forces of the saddle support tube, 1.6. whereas the bores are located in the area of the smallest stress of the saddle support tube. ### Claim 2 (depends on 1) The height adjustable saddle pole according to claim 1, wherein the locking pin in the latched position accompanies the movement of the saddle support tube more or less in the direction and in the opposite direction of the cross product of the vector of the longitudinal axis of the cladding tube with the vector of the longitudinal axis of the locking pin. ### Claim 3 (depends on 1) The height adjustable saddle pole according to claim 1, wherein the locking pin has a first flattening in the peripheral area of its front end. ### Claim 4 (depends on 1) The height adjustable saddle pole according to claim 1, wherein the locking pin comprises second flattenings into the partial regions of its periphery on which the bores of the saddle support tube have the largest relative movement with respect to the locking pin. ### Claim 5 (depends on 1) The height adjustable saddle pole according to claim 1, wherein the contour of the locking pin on its front end is adapted to the contour of the saddle support tube. ### Claim 6 (depends on 1) The height adjustable saddle pole according to claim 1, wherein the locking pin is designed in such a way that it absorbs the load in direction of the longitudinal axis of the cladding tube over its surface in its guide. ### Claim 7 (depends on 1) The height adjustable saddle pole according to claim 1, wherein a lever mechanism is provided for bringing the locking pin into the latched and into the unlatched position. ### Claim 8 (depends on 6) The height adjustable saddle pole according to claim 6, wherein the lever mechanism is designed in such a way that it allows the movement of the bore caused by the load of the saddle support tube. ### Claim 9 (depends on 1) The height adjustable saddle pole according to claim 1, wherein the adjustment of the locking pin is done via a sliding guide mechanism. ### Claim 10 (depends on 1) The height adjustable saddle pole according to claim 1, wherein a portion of the mechanism for actuating the locking pin is arranged around the periphery of the cladding tube. ### Claim 11 (depends on 1) The height adjustable saddle pole according to claim 1, wherein a Bowden cable is provided for adjusting the locking pin. ### Claim 12 (depends on 1) The height adjustable saddle pole according to claim 1, wherein the spring element is a pneumatic spring. ### Claim 13 (depends on 1) The height adjustable saddle pole according to claim 1, wherein the cladding tube is the saddle tube of a bicycle. ### Claim 14 (depends on 1) The height adjustable saddle pole according to claim 1, wherein means are provided to prevent any twisting of the saddle support tube with respect to the cladding tube. ### Claim 15 (depends on 1) The height adjustable saddle pole according to claim 1, wherein a pinhole closure is provided for sealing the bores, which opens in reaction to the force of the locking pin. ### Claim 16 (depends on 1) The height adjustable saddle pole according to claim 1, wherein the upper end of the external tube of the pneumatic spring is fixed at the upper end of the saddle support tube. ### Claim 17 (depends on 1) The height adjustable saddle pole according to claim 1, wherein a wiping device is provided, which comprises a felt ring. ### Claim 18 (depends on 1) The height adjustable saddle pole according to claim 1, wherein the locking pin consists of a high performance plastic.
