Definitions

  • the invention relates to a limit stop for the pivot angle of an arm movable about a bearing axis, in which a strut is articulated on the one hand on the component supporting the bearing axis, which on the other hand engages the arm at a distance from the bearing axis, in which the strut consists of two structurally identical tabs
  • Each has a longitudinal slot containing an extension and a stop projection upstream of this longitudinal slot and protruding from the link plane, in which the stop projection of each link can only be moved longitudinally by extension into the longitudinal slot of the other link, and in which the stop end of the longitudinal slot each tab whose stop projection is adjacent.
  • a limit stop of this type belongs to the prior art with FR-A 2 148 720.
  • DE-C 161 114 and DE-C 250 666 also include limit stops to the state of the art, which, to form a strut, have two tabs which are relatively displaceable relative to one another and which are equipped with claws angled out of the tab plane for mutual guidance.
  • these claws have such an arrangement that they can only interact with the longitudinal boundary edges of the tabs, they are also assembled in such a way that they can only be detached from one another again by plastic deformation of the claws.
  • the object of the invention is to provide a generic limit stop which has a structurally simple design with a relatively small installation space and high functional reliability.
  • Such a limit stop is characterized by the characterizing features of claim 1, namely in that each stop projection is formed by a tongue angled directly out of the tab plane, which has laterally projecting support lugs at its end, that the extension of the longitudinal slot at the end of the stop End of the longitudinal slot is provided, and that the relative displacement of the tabs to one another can be limited to a dimension which is less than the distance between the stop end and the extension formed by an end notch of the longitudinal slots of both tabs.
  • the mutually facing ends of both tabs can only be pivoted on the one hand to the bearing-bearing component and on the other hand to the arm, while claim 3 provides that the tabs of the strut consist of strip material with a flat rectangular cross-section.
  • the tabs for forming a limit stop according to the invention can be easily and simply manufactured as stamped and bent parts, and that two of these tabs can be put together by simple plug-in coupling connections to form a strut that serves as a limit stop and can be adjusted within predetermined limits.
  • Fig. 1 of the drawing is shown in a schematically simplified representation, namely by a dash-dotted line, the fixed frame 1 of a window, a door or the like, on which a wing 3 is pivotally suspended via a support and guide link system 2.
  • the support and guide link system 2 has a support arm 4 which is suspended on the fixed frame 1 so as to be pivotable about a bearing axis 5. With the support arm 4 two links 8 and 9 are connected via two pivot pins 6 and 7, which have a matching length dimension. Each of the links 8 and 9 is in turn connected via a respective pivot pin 10 or 11 to a guide rail 12 which can be fixed on the wing 3, lying parallel to its plane.
  • the section of the support arm 4 located between the pivot pins 6 and 7 forms, with the two links 8 and 9 and with the guide rail 12 carrying the two pivot pins 10 and 11, a link parallelogram 13 which connects the wing 3 to the fixed frame 1.
  • the movement of the handlebar parallelogram 13 is influenced by a control arm 14 which is pivotally suspended on the one hand about a hinge pin 15 on the fixed frame and on the other hand with a hinge pin 16 between the Ge Steering pin 6 and 10 attacks the handlebar 8.
  • the control arm 14 acts on the parallelogram 13 so that the wing 3 is guided in its opening and closing movement along a path which is at least approximately delimited by a circular arc around a latent hinge axis which is in the vicinity of the bearing points 5 and 15 adjacent side edge of the wing 3 is.
  • a strut 17 is therefore used as a limit stop for the pivoting angle of the support arm 4, which is pivotally suspended on the one hand and the articulation pin 18 on the fixed frame 1 and on the other hand acts on the support arm 4, for example via the articulation pin 6, at a distance from the bearing axis 5.
  • the strut 17 is formed by two identical tabs 19a and 19b. Each of these tabs 19a and 19b has a longitudinal slot 20a and 20b and is also provided with a stop tongue 21a and 21b angled out of the tab plane.
  • each bracket 19a or 19b engages in the longitudinal slot 20b or 20a of the other bracket 19b or 19a only in a longitudinally displaceable manner.
  • the stop end 22b or 22a of the longitudinal slot 20b or 20a of each tab 19b or 19a is provided adjacent to the stop tongue 21b or 21a.
  • the distance between the articulation axes 6 and 18 thereof is limited to the dimension 23.
  • the stop tongue 21a of the bracket 20a then interacts with the stop end 22b in the longitudinal slot 20b of the bracket 19b, while conversely the stop tongue 21b of the bracket 19b comes into contact with the stop end 22a in the longitudinal slot 20a of the bracket 19a that can be clearly seen in FIG. 1.
  • each stop tongue 21a and 21b has support lugs 24a and 24b which project laterally at its free end. These support lugs 24a and 24b can only in the area of an extended end notch 25a or 25b, which is assigned to the end of the longitudinal slot 20a or 20b remote from the stop end 22a or 22b, with the longitudinal edges of the longitudinal slots 20a or 20b in support and Hold intervention are brought.
  • the relative displacement of the brackets 19a and 19b to each other is limited to a dimension 26, which is the distance between the stop end 22a or 22b and the extended end notch 25a or 25b of the longitudinal slots 20a and 20b falls below both tabs 19a and 19b. Unwanted and automatic decoupling. the two straps 17a and 19b forming the strut 17 are thereby counteracted in a simple manner.
  • the two tabs 19a and 19b of the strut 17 are structurally completely identical and can therefore be manufactured as stamped and bent parts in one and the same tool, preferably from strip material with a flat rectangular cross section. It is important that the stop tongues 21 a and 21 b of the two tabs 19a and 19b only engage in the longitudinal slots 20b and 20a assigned to them in a longitudinally displaceable manner, while the free ends of the strut 17 are only pivotably held on the pivot pins 6 and 18.
  • the use of the strut 17 as a limit stop for the swivel angle of an arm movable about a bearing axis is not limited to support and guide link systems 2, as shown in FIG. 1. Rather, a limit stop formed by the strut 17 can be used wherever the aim is to limit the swivel angle for an arm movable about a bearing axis relative to the component carrying the bearing axis.
