  • Known bike holders above all if there is a plurality of bikes which are to be carried, have proved to be defective in certain respects. Such a defect is that certain bike holders have to be dismounted from the coupling ball, or that bikes have to be removed from the bike holder, before the boot of the vehicle can be opened.
  • Another known defect is that it may be problematic to achieve enough clamping force safety to keep the bike holder on the coupling ball in the desired position and also that it may be difficult to mount the bike holder on the coupling ball in a safe manner.

  • An additional disadvantage is that the clamping mechanism at the connection to a coupling ball have to be locked with a locking pin in the connected position in order not to be released by the reaction forces, which implies a certain security risk.
  • Another type of bike holders is known through SE 532993, with a clamping mechanism intended to be clamped on a coupling ball.
  • the clamping mechanism includes a housing and a pivotable clamping means, with a toggle joint linked to the housing.

  • a pressure plate is arranged between the housing and the pivotable clamping means.
  • a similar bike holder is also known through US 5,344,174, where one benefits from one clamp half being stationary arranged at the housing.
  • the devices have constructions implying certain drawbacks as to resistance and require comparatively much maintenance.
  • DE 202005004043 describes another load carrier intended to be connected to the rear part of a vehicle, a stationary frame element carries a movable support means with a load carrier. Further, there is a sliding and tilting arrangement for keeping the frame element and the support means together. A locking element enables locking of the support means in a first end position. After unlocking, the support means may be displaced to a second end position, in which a tilting of the support means is possible.

  • the man skilled in the art realizes that many of the shown functions according to the invention may be fulfilled by an inverted principle, such for instance that instead of having pins to guide the motion of the locking arm 14, one can instead invert this and arrange pins at the side walls 17 to guide the corresponding grooves in the locking arms.
  • the angle motions which have proved to be possible with a tie arm according to Fig. 11 may be varied depending on need, i.a.
  • the arm may be constructed to pivot a larger angle region but let the lockable angle region be the same, or, on the contrary, to reduce the total pivotable region, etc.
  • the total pivotable region serve an important purpose in many cases when the tie arm in a flexible manner is to be moved through several bike frames, i.e. a movement which may require a comparatively large freedom of movement, while the locking itself often requires an essentially small angle region to be able to achieve a safe locking of the bikes.
  • the lockable region is determined by the two opposite parts of the pivotable joint which is arranged with tooth elements, which thus offers the possibility to fasten the two arm parts in angles in relation to each other.

Abstract

La présente invention concerne un dispositif d'attelage sur une boule d'attelage ou tout autre élément de fixation similaire. Ledit dispositif d'attelage comprend une moitié de serrage avant (10) et une moitié de serrage arrière (11) qui comportent des surfaces de serrage (100, 110) agencées pour pouvoir être fixées à une boule d'attelage (D) ou tout élément de fixation similaire, un logement (18) qui comprend deux parois latérales (17), au niveau desquelles et entre lesquelles un premier élément (12) et un second élément (16) sont agencés, lesdits éléments étant des éléments de transmission de force et d'absorption de force, dont au moins un desdits éléments de transmission de force (12) est un axe/arbre (A), autour duquel au moins une des moitiés de serrage (10, 11) est suspendue de façon pivotante, une poignée (14) raccordée à un mécanisme de fixation (14, 15, 19), pour la fixation et la libération, respectivement, du dispositif d'attelage, lequel mécanisme de fixation (14, 15, 19) comprend un axe/arbre (C) qui peut pivoter par rapport au logement, et un moyen de réglage (13) agencé pour permettre le réglage de la force de fixation à partir des moitiés de serrage (10, 11). Dans ladite présente invention, ledit mécanisme de fixation (14, 15, 19) comprend un corps excentrique (145) qui comporte une surface de fixation (146) agencée pour être fixée contre une surface de serrage (104) d'une desdites moitiés de serrage (10, 11).
