Definitions

  • the invention relates to a height adjustable saddle pole (S) consisting of two tubes which are telescopically slidable into another, that is to say a cladding tube for accommodating a saddle support tube, a spring element acting upon the saddle support tube, a locking device, which is installed on the cladding tube with a locking pin, a guide for the locking pin, 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 whereas at least two axially spaced apart bores are provided in the saddle support tube for accommodating the locking pin and whereas the locking pin in the latched position engages into one of the bores through a recess of the cladding tube and thus completely absorbs the axial forces of the saddle support tube ( 16 ).
  • S height adjustable saddle pole
  • Saddle poles for fastening bicycle saddles are usually fixed in the saddle tube with a mechanical clamp. Consequently, the saddle tube is generally slit at the upper end so that the periphery of the tube is reduced by the clamping effect and thus the saddle tube bears upon the saddle pole with a positive fit.
  • the clamp is tightened with a nut or a quick clamping device is used, at which the clamping force is reached by changing the position of a lever.
  • a “quick release lever” enables to adjust the height of the saddle and to fix it without tool. Such is for example necessary if the bicycle is going to be ridden by people of different size or if the saddle should be adapted for one and the same rider using certain parameters.
  • the height of the saddle must be adjusted optimally from an ergonomic viewpoint so as to achieve good power transmission.
  • the rider When going downhill, the rider must shift his centre of gravity backwards and downwards according to the steepness and to the difficulty and for that purpose he must often bring his buttocks behind the saddle.
  • the deeper the saddle the easier the rider can shift his centre of gravity actively and dynamically, but thereby also loses on cornering forces which he can press with the inside of its thighs against the saddle when the latter is accordingly in a raised position
  • the optimal height of the saddle therefore depends on the respective riding condition.
  • Height adjustable saddle poles are disclosed in the state of the art which function after the principle of hydraulic locking.
  • the saddle poles described in the German utility model DE 20 2007 014515 U1 (Kindshock) or in the document U.S. Pat. No. 7,083,180 B2 (Paul Turner) operate with two oil chambers which are connected to one another by a valve.
  • a tube can be moved up and down in the shank by opening the valve with the trigger.
  • the lower oil chamber is additionally filled with air so as to generate a force upwards. Consequently the pole is pressed upwards by pulling the trigger and releasing it simultaneously.
  • the trigger is always actuated at the upper end of the saddle support tube via a lever.
  • Said lever can be actuated manually directly on the head of the saddle pole.
  • a Bowden cable can be provided from the handlebar for remote actuation of the device via an appropriate mechanism.
  • a height adjustable saddle pole is disclosed in the international patent application WO 2007/117884 A2 with which a bolt is brought into a recess of a saddle support tube, through a recess of a cladding tube, in a latched position from the outside.
  • the bolt is operated by means of a magnet for adjusting the saddle pole.
  • the mechanism is designed in such a way that the shear force maintains the locking bolt in the locking position as long as the bolt can be loosened by the own weight of the rider. It is hence not possible for example to adjust the height of the saddle pole when the rider is standing on the pedals.
  • the mechanism is relatively expensive and the bores are located on the front or on the back in the driving direction, so that the static of the saddle support tube is weakened maximally.
  • the object of the invention is hence to remedy the shortcomings aforementioned.
  • Another purpose of this invention is to provide a pole which is of simple design and easy to maintain, and which allows for adjustment ranges with a lift of more than 150 mm.
  • the invention should besides provide a solution for a remote control cable running parallel on the cladding tube.
  • the term “bore” should be understood as a recess, i.e. it need not strictly be a circular hole but also other geometrical recesses can be provided, for example also conical recesses and/or blind hole-shaped recesses, etc.
  • region is meant that the centre of a bore or recess need not exactly coincide with a point of the neutral fibre, but that it is important to arrange the recesses in regions which do not weaken the saddle support tube so much.
  • the stress in a saddle support tube is generated by the load of the rider, whose weight force pushes the saddle support tube backwards and downwards. This is due to the fact that the saddle tube (this is the tube of the bicycle which receives the saddle pole) extends obliquely from the receiving opening of the saddle pole forwards and downwards to the bottom bracket bearing.
  • the tensile stress is therefore maximum in the front fibre of the saddle support tube in the driving direction (the compressive stress is accordingly maximum in the rear fibre in the driving direction).
  • the “neutral” fibre of a saddle support tube lies laterally offset by nearly 90 degrees from the maximally stressed fibres. The region of the neutral fibre is hence the region of the smallest stress and hence the optimal region for mounting the locking device.
  • the saddle support tube and hence the bore of the saddle support tube move marginally backwards (indications such as “backwards”, “forwards”, “laterally” are always related to the driving direction), so that the latched locking pin under load is pushed in this direction. It is hence advantageous that 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.
  • the degree of freedom of the locking pin can be achieved through suitable mounting of the locking pin or its guide.
  • the locking pin has a first flattening or phase in the peripheral area of its front end.
  • the locking pin can hence be latched in the bore more easily.
  • the locking pin in 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 contains second larger flattenings so that latching is then secured when the deflection of the saddle support tube is maximum.
  • the contour of the locking pin on its front end matches the contour of the saddle support tube.
  • the locking pin lies thereby already over its surface on the saddle support tube and can hence be brought in the latched position faster, not to mention the release which is also facilitated. All the more so if implemented in combination with the flattenings.
  • the locking pin is arranged in such a way that it absorbs the load in direction of the longitudinal axis of the cladding tube (28) or of the saddle support tube over its surface in its guide. In the axial direction, the locking pin must absorb almost the whole weight force of the rider. The force should therefore be absorbed flatly as far as possible, preferably by a plane surface area.
  • the locking pin can hence advantageously be brought into the latched position and into the unlatched position. It is hence meaningful since the force which has to be exerted can be transformed with a lever.
  • the locking pin should consequently allow the movement of the bore which is caused by the load of the saddle pole.
  • the adjustment of the locking pin is done via a slotted guide mechanism.
  • a slotted guide mechanism allows on the one hand to achieve a particularly small design and on the other hand the distance-force curve can be set up and optimised via the design of the sliding path.
  • the size of the structure of the whole device can be reduced particularly advantageously in such a way that a portion of the mechanism for actuating the locking pin is arranged around the periphery of the cladding tube.
  • the locking mechanism is actuated via a Bowden cable.
  • shifters or similar actuating devices are provided for actuating such a Bowden cable, which can be fixed to the handlebar of a bicycle, so that the rider can release the height adjustment mechanism during riding.
  • An advantageous variation of the invention consists in that the spring element acting upon the saddle support tube is a pneumatic spring. This enables to achieve a relatively flat spring characteristic and a practically constant extension force as well. Such pneumatic springs are commercially available at low cost.
  • the cladding tube is the saddle tube of a bicycle.
  • means should be provided to prevent any twisting of the saddle support tube with respect to the cladding tube. This substantially facilitates the adjustment for the rider while riding, since otherwise the saddle might easily be twisted during the adjustment and the locking pin would not latch.
  • An advantageous variation of the invention consists in that a pinhole closure is provided for sealing the bores which opens in reaction to the force of the locking pin 61 . This prevents the ingress of dirt through the bores.
  • the upper end of the external tube of the pneumatic spring or gas spring is fixed at the upper end of the saddle support tube. This hence prevents the saddle pole from falling out or being removed completely. This enables moreover to define the end stop of the maximum extended position of the saddle support tube, which is also adjustable in height through the setting of the pneumatic spring.
  • An advantageous variation of the invention consists finally in that a wiping device is provided, which contains a felt ring 3 .
  • a wiping device which contains a felt ring 3 .
  • the felt ring can be soaked with oil so that the saddle support tube is coated with a thin oil film due to the up and down movement and thus absorbs less dirt. Better sliding properties can thus also be obtained.

  • the locking device V to which the saddle support tube 16 is fixable relative to the cladding tube, is installed at the upper end of the cladding tube 28 .

  • the pre-wiper ring 1 should hence wipe the coarse dirt, when the saddle pole is pushed downwards.
  • the wiper ring 2 then takes over the precision work.
  • the use of the felt ring 3 is particularly advantageous. It can be soaked with oil, so that the saddle support tube is always wetted with a thin, dirt repelling oil film.
  • the plastic bush 23 enables the saddle support tube 16 to slide in the cladding tube 28 easily. It also absorbs the radial forces of the saddle pole.
  • the pre-wiper ring 1 is screwed on the clamping nut 4 and hence fixes the wiper ring 2 and the felt ring 3 .

  • the locking pin 61 is represented together with the tilting lever 6 and the slotted slider 9 assembled together.
  • the locking pin 61 has in its guide 52 a clearance in the direction of the double arrow SP, whereas the direction of the double arrow SP results from the cross product of the vector of the longitudinal axis A 28 of the cladding tube 28 with the vector of the longitudinal axis A 61 of the locking pin 61 .

  • FIG. 10 shows the forces acting upon the saddle support tube 16 and the cladding tube 28 .
  • the force FF caused by the rider is regularly exerted against the driving direction, backwards and downwards. It finds a counter-bearing at the upper rear end of the cladding tube through the force FHO as well as in the front area of the cladding tube 28 , against which the guide bushing XX, which is situated at the lower end of the saddle support tube, are pushed by the leverage effect (force arrow FHN).
  • the resulting force FV in the axial direction downwards is absorbed by the locking pin 61 (not illustrated here)
  • the result is thus the stress curve indicated schematically in the saddle support tube 16 , which is a superposition of compression and bending stresses.
  • the portion of the compression stress DS is greater in the upper section than in the lower section due to the short lever length of the radial force components. Consequently, the neutral fibre NF is shifted forwards a little.
  • the amount of stress in the tube cross-section is however minimal, so that the upper bore (even if it is a little remote from the neutral fibre NF) does not compromise the operational stability of the whole system.
  • the portion of bending stress is significantly larger in the lower section.
  • the neutral fibre NF is consequently close to the centre line.
  • the amount of stresses is the greatest at the entrance into the cladding tube 28 . It is clearly visible in combination with these embodiments that the bores ( 29 , 29 ′, 29 ′′) are located in the area of the smallest bending stress, i.e. close to the neutral fibre NF of the saddle support tube 16 ).
