Definitions

  • Detent device for a rotationally or translationally movable
  • the invention relates to a locking device for a rotationally or translationally movable operating element.
  • Detent devices for operating elements of the aforementioned type are described for example in DE-C-37 27 495, DE-A-10 2001 087 829, DE-B-10 2007 013 383, DE-A-10 2006 036 636, DE-A-103 23 544, DE-A-102 36 066 and WO-A-2013/083554.
  • the known locking devices operate with a spring-mounted locking projection, which is usually designed as a spring steel leaf spring and is in sliding contact with a detent gate, which has a plurality of detent recesses and between these arranged grid increments.
  • the Rastkulisse is as Wavy detent path formed having a continuous continuous surface.
  • the object of the invention is to provide a minimized rotational tolerances locking device for a rotatory or translationally movable control element.
  • a locking device for a rotary or translationally movable control element is proposed with the invention, wherein the locking device is provided with
  • Rastkulisse which has several alternately successive detent recesses and grid increments
  • detent recesses and the grid increments have a wave-shaped or substantially wave-shaped, a differentiable curve descriptive detent path with alternately successive detent lows and detent high points and the outer surface of the locking projection slides in a relative movement of locking projection and detent gate on the detent track along and
  • the course of the curve of the detent track in its rest areas under deviation from the wave form has in each case rectilinear sections, wherein the course of the detent track at the transitions of the rectilinear sections to the respectively adjacent undulating sections is likewise each differentiable.
  • the basically undulating detent path has rectilinear or planar sections. These rectilinear sections in the wave-shaped curve of the detent track lie on both sides of each detent path deep point and in relation to this pairwise symmetrical to each other.
  • the curve course of the detent track thus remains curving or tangent-continuous over the entire course of the detent track, since according to the invention the rectilinear sections (in a mathematical sense) can be differentiated into the curve course of the detent track.
  • the continuous and repeatedly variable detent gate geometry is tangent-continuous or, preferably, curvature-continuous.
  • An example geometry is that of a sinusoid.
  • the continuously and continuously changing geometry in the course of the latching track forms a common contact point with the latching projection or its bulging outer surface.
  • This contact point (interface between the link geometry and the latching projection) is variable in the rest positions of the latching projection, in which this is resiliently biased in the region of a Rastbahn low point, depending on the dimensions of the protrusion of the outer surface of the latching projection.
  • this is the tangent or curvature continuous attack angle of the locking projection on the locking geometry in the rest position of the locking projection of different sizes. This then results in different sized movement torque fluctuations (Ausrastmomente).
  • the locking device less susceptible to tolerances by sections are replaced in the course of the detent path through rectilinear sections.
  • the extension of these rectilinear sections is to be selected larger than the manufacturing and assembly tolerance-related area within which the contact points of the locking projection lie in its rest or detent position.
  • the rectilinear portions pass over into the wave-shaped basic geometry of the detent gate detent track with curvature or tangent continuity. Due to the fact that the rectilinear sections have a constant pitch angle, the disengagement torque is also kept substantially constant. As a result, torque fluctuations or Ausrastmoment fluctuations are kept small.
  • the extent of each straight section of the curve of the detent track is less than 30% and preferably more than 5%, in particular more than 10% of the extent of the Detent path between a Rastbahn low point and a directly adjacent to this Rastbahn high point.
  • the latching device or the haptic system represented by the latching latching system and locking projection is less susceptible to wear and manufacturing tolerances. This is manifested by a reduction in the moment of movement
  • a section of a locking device acting as a detent for example, a turntable for a vehicle component operating unit is shown, wherein a locking projection is in its rest position in a detent recess of a detent track.
  • the latching device 10 has a resilient or resiliently mounted latching projection 12, which is formed in this embodiment as a bulging spring steel strap.
  • the latching projection 12 has a convexly curved outer surface 14. For reasons of better clarity, the latching projection 12 is not shown in contact with the latching track 30 in the drawing.
  • the detent gate 18 is usually made of plastic material and has a plurality of alternately successive detent recesses 20 and pitches 22. Each detent recess 20 has a low point 24, while for each grid increase 22 a high point or apex 26 belongs.
  • Low and high points 24,26 define together with the respective intermediate edge portions 28 a wave-shaped latching track 30, the Top of the detent gate 18 forms and along which the locking projection 12 slides in relative movement with the detent gate 18 along.
  • the course of the latching track 30 is substantially sinusoidal.
  • rectilinear sections 32 are introduced into the undulating course of the latching track 30. These rectilinear portions 32 are within the flank regions 28 of the latching track 30 and in pairs symmetrically to each other, wherein the respective axis of symmetry 34 in each case by a detent path low point 24 extends.
  • the position of these rectilinear sections 32 and their extension depends on the position and the size of the rest position regions 36, in which the locking projection 12 in the locking position (or in the locking positions) due to manufacturing and assembly tolerances on the latching track 30 can rest.
  • the two contact points 38 between latching projection 12 and latching track 30 are located at the ends of the two dashed auxiliary lines 40. It can also be considered that the positions of these contact points 38 may change over time due to wear. In any case, ensure the rectilinear portions 32 due to their constant slope that the Ausrastmoment does not change substantially, which applies both to the Ausrastmomente a manufacturing series of locking devices and the Ausrastmoment one and the same locking device over its life cycle.
  • the extent of the extension of the curve of the detent track 30 between a detent lane low point 24 and the adjacent Rastbahn high point 26 is shown.
  • the extent 44 of the rectilinear portion 32 lying in this area is at least 5% or at least 10% and preferably at most 30% or 20% of this extension 42. It is also important that the course of the latching track 30 at the transitions 46 of the rectilinear Sections 32 to the adjacent curved course sections 48,50 of the latching track 30 are differentiable, so that the latching track is viewed over its entire course differentiated.

Abstract

L'invention concerne un dispositif d'arrêt destiné à un élément de commande mobile en rotation ou en translation. Ledit dispositif est pourvu d'un taquet d'arrêt (12) monté élastiquement et présentant une surface extérieure (14) de courbure convexe et d'une coulisse d'arrêt (18) qui est en contact glissant avec la surface extérieure (14) du taquet d'arrêt (12) et qui comporte plusieurs creux d'arrêt (20) alternant avec des bosses d'arrêt (22). Les creux d'arrêt (20) et les bosses d'arrêt (22) forment une glissière d'arrêt (30) ondulée ou sensiblement ondulée, qui décrit une allure de courbe différenciable, et qui comprend des points bas (24) alternant avec des points hauts (26). La surface extérieure (14) du taquet d'arrêt (12) glisse le long de la glissière d'arrêt (30) lors d'un déplacement relatif entre le taquet d'arrêt (12) et la coulisse d'arrêt (18). Lorsque le taquet d'arrêt (12) se trouve dans les positions d'arrêt, sa surface extérieure (14), dans des zones d'appui au repos de la glissière d'arrêt (30) disposées de manière symétrique par rapport à un point bas (24) respectif de la glissière, repose contre cette dernière. Le tracé de la courbe de la glissière d'arrêt (30) présente dans ses zones d'appui au repos, à la différence de la forme ondulée, respectivement des parties rectilignes (32). Le tracé de la glissière d'arrêt (30) est respectivement également différenciable au niveau des transitions (46) entre les parties rectilignes (32) et les parties ondulées (48, 50) respectivement voisines.
