Definitions

  • a saddle pin The function of a saddle pin is to retain a saddle in a desired position, as well as enabling necessary adjustments of for the bicycle seat or saddle. Height adjustment may be performed satisfactory by releasing the stem from the carrying frame tube.
  • a drawback with known saddle pins is that they provide limited adjustment of the seat in the longitudinal direction of the bicycle.
  • Another disadvantage with known saddle pins is their relatively heavy weight.
  • a saddle pin having a tubular stem and two clamping elements at the head of the saddle pin, which clamping elements can be pressed together around two parallell carrying rods of the seat, using a screw acting against a nut.
  • One of the clamping elements can be arcuate and oppose a corresponding arcuate surface on the head of the saddle pin so that the two arcuate surfaces can be adjusted relative to each other. In this way it is possible to adjust the slant of the saddle within a limited range. Furthermore it is possible to move the carrying rods and thus the seat between the two clamping elements, so that the position of the seat in the longitudinal direction of the bicycle can be adjusted.
  • This known solution has two main disadvantages. First, a number of elements are required, namely two clamping elements, one screw and one nut. Following from this, a further disadvantage occurs; this known solution can not be adapted for automatic assembly.
  • the main object of present invention is to provide a more simple and thus a lighter saddle pin which is especially suitable for manufacuring from lightweight metal or an alloy thereof.
  • a further object is to adapt the structure to automatic assembly. These objects should be achieved without renouncing the desirable adjustment, that is the variation of the slant of the seat and its location in the longitudinal direction of the bicycle. Furthermore it is desireable that the assembly, in case it is carried out manually, can be done quickly and easily and that it is easy to adjust the seat.
  • a saddle pin of this kind can be made with less parts and therefore have a lower weight than corresponding known saddle pins. Consequently, it is possible to preassamble the saddle pin and thus make production thereof easier.
  • the saddle pin according to the invention is made ready for automatic assembly. Also it is constructed so that adjustment and regulation can be done in a simpel manner and without loss of flexibility.
  • Fig. 1 shows an axially sectional view through a saddle pin according to the invention
  • Fig. 2 shows a sectional view taken at line JT-II of Fig. 1.
  • the saddle pin in. the example comprises a tubular stem 11 adapted for insertion and clamping in a frame tube of a bicycle, and a head or an upper section 12 which is integral with the stem.
  • This section of the saddle pin can be manufactured in a per se known manner from aluminium or lightweight metal alloy.
  • the head 12 comprises a cantilevered lobe 13 forming a upwardly directed, arcuate surface 14 having transverse grooves.
  • the slot between the lips 16 and 17 is centrally located relative to the arcuate surface 14, and lobe 13 is provided with an aperture 19 orientated axially relative to the axis of symmetry .
  • the pressure yoke 18 has a length which exceeds the width of head 12, slightly more than the total distance between the connection elements of a bicycle saddle to be attached and which will be described in more detail later. This means that pressure yoke 18 will extend both sides of the head 12 as is shown in Fig. 2.
  • the pressure yoke 18 has a centrally threaded opening 20 adapted for insertion of bolt 21 so that the pressure yoke 18 can be drawn toward surface 14.
  • the lower side of the pressure yoke, which facer surface 14, is provided with a pair of grooves 22 and 23 which are of curved cross-section and which form grooves for two carrying rods 24, 25 which are components of a bicycle saddle to be attached.
  • Each saddle shaped groove 22 and 23 has a curvature transverse to the longitudinal axis of the pressure yoke 18, which corresponds or is approximately similar to the curve of the surface 14. This means that a slot is formed having approximately similar transverse extension between the surface 14 and the surfaces of the saddle 22, 23.
  • grooves 22, 23 are transversly curved such as to correspond to or partly exceed the radius of the carrying rods 24 and 25.
  • the carrying rods 24, 25 are spaced at a distance aproximately similar to or partly exceeding the width of the head 12 of the saddle pin, which again can be approximately the same as the diameter of the stem 11.
  • a clamping plate 26 is loosly inserted to engage with surface 14.
  • Plate 26 has an arcuate surface which contacts with surface 14 and extends beyond the sides of the head 12 in a similar manner to transverse yoke 18.
  • claimping plate 26 is provided with longtudinal parallel grooves 27 and 28, which in assembled condition are situated opposite grooves 22 and 23 of the pressure yoke 18.
  • a clamping jaw is formed at each side of the saddle pin and which can clamp around respective carrying rods 24, 25.
  • the clamping plate 26 is provided with a central slot 29 extending in the same direction as lobe 13 thereby enabling the pressure plate 26 to move relative to surface 14, and in this way vary the angle of the grooves 27, 28. It is thus possible to adjust the clamping plate 26 to vary the slope of the carrying rods 24, 25 and thus of the bicycle saddle.
  • the clamping opening and the power geometry makes it possible to tighten the bolt 21 without disturbing the adjustment.
  • the clamping plate 26 is grooved against the surface 14.
  • the above described embodiment can be modified in different ways. For example it is possible to interchange the claw shaped lips 16, 17 with another shape for supporting or locking of the transverse yoke 18. Furthermore it is possible to direct aperture 19 through the head so as to terminate in the stem 11, even though this makes the access to the bolt 21 more difficult.

Abstract

Tube de selle servant à monter une selle de bicyclette, dans lequel est situé, au niveau de sa partie de tête (12), une surface de support incurvée (14) constituant le support d'une plaque de serrage (26) pourvue de rainures (27, 28) s'accouplant à une paire de tiges de support (24, 25) de la selle de bicyclette. En réglant la position de la plaque de serrage sur la surface de support incurvée, on peut positionner ladite plaque de serrage selon des angles d'inclinaison différents. Un boulon (21) s'étend dans un sens perpendiculaire aux tiges de support, afin de s'accoupler avec un collier de pression (18), dont les extrémités sont conçues pour s'accoupler avec les tiges de support (24, 25). La tête (12) du tube de selle comprend une paire de becs en forme de griffes (16, 17) s'adaptant aux côtés du collier de pression (18).
