Definitions

  • the invention relates to a snap fixation of a door leaf with a spring-loaded locking element guided in a housing and a locking element, locking element and locking element engaging at a predeterminable pivoting angle of the door leaf, in particular in the closed position, and being separable again by pivoting the door leaf .
  • Known devices of this type have an axially displaceable, spring-loaded locking element with end slopes provided, by means of which the locking element is lifted vertically when it hits the locking element and, after having overcome a locking projection provided on the locking element, can reach a locking recess.
  • a disadvantage of these known devices is, above all, that they are difficult to move, because relatively high pretensioning forces are required for the locking element to ensure a sufficient holding action. This high pretension in turn also leads to an increase in the friction forces occurring during operation and thus to a corresponding wear.
  • the object of the invention is to design a device of the type mentioned at the outset with little technical effort so that, on the one hand, higher holding forces can be achieved and, on the other hand, a particular ease of movement can be ensured despite the high holding forces.
  • the locking element is designed as a locking rocker and by means of the locking element having at least one locking trough with simultaneous axial displacement about a pivot axis into an over-center position can be transferred, in which the latch rocker is supported in an inclined position in the locking recess.
  • the design of the locking element as a locking rocker during the process of transferring the locking rocker into the locking trough achieves an advantageous reduction in force with regard to the prevailing spring preload and thus the desired ease of movement, while in the fixing position a play-free holding of the door leaf is ensured due to the inclined position of the locking rocker and also the desired high holding force is ensured, since the dead center position of the locking rocker must first be overcome before loosening the fixation.
  • the locking rocker can be mounted on a pivot in a housing-fixed swivel-slide guide or via a guide slot on a swivel axis fixed in the housing.
  • a pivot in a housing-fixed swivel-slide guide or via a guide slot on a swivel axis fixed in the housing can be mounted on a pivot in a housing-fixed swivel-slide guide or via a guide slot on a swivel axis fixed in the housing.
  • the locking rocker is expediently supported on a pressure body which is axially displaceably guided in the housing and which moves the locking rocker into the basic position, i.e. biased into the position aligned with the longitudinal axis of the housing, specifically by means of a spring unit which is adjustable in particular with regard to the spring force exerted.
  • Figure 1 shows a device for snap fixing a door leaf with a housing 1, in which a pressure body 2 is arranged displaceably mounted in the axial direction, which is under the biasing force of a spring 3.
  • the pressure body 2 has a slot-like recess 4, in the area of which there is a screw receptacle 5 for fastening the device, in particular on the frame of a door.
  • a locking rocker 6 is acted upon by the pressure body 2 and is mounted in a swivel-slide guide 7 via a bearing attachment 8.
  • the swivel-slide guide 7 can either be formed in one piece with the housing or be formed in a separate component that can be coupled to the housing 1 in a form-fitting and non-positive manner.
  • the locking rocker 6 interacts with a locking element 9 intended for attachment to a wing, which in the exemplary embodiment shown is of central symmetry and has a locking recess 10 for the left and right stop.
  • Each locking trough 10 is bounded on the outside by a locking projection 11.
  • a headstock 12 cooperating with the locking member 9 is integrally formed, but this has no significance for the function of the device for snap fixing.
  • FIG. 1 shows the device in the fixing position, in which the locking rocker 6 is located in the locking recess 10.
  • the latch rocker 6 assumes an over-center position, i.e. that before loosening the fixation, the locking rocker 6 must first be brought into the position aligned with the longitudinal axis of the housing and then swiveled in the opposite direction in order to overcome the locking projection 11.
  • FIG. 3 shows a variant of the device according to FIG. 1, in which the locking rocker 6 is mounted on a pivot axis 14 fixed to the housing via a guide slot 15.
  • the spring 3 can be adjusted with regard to its pretension via a schematically illustrated eccentric element 13, which in principle also applies to the embodiment according to FIG. 1.
  • FIG. 3 shows the device not in the locked position, but at the moment when the locking begins. If the locking member moves further to the left and thus the wing is brought into the closed position, then the locking rocker is tilted to overcome the locking projection 11 on the one hand about the axis 14 and on the other hand raised against the force of the biasing spring 3 with displacement of the pressure body 2 and then snaps into the locking trough 10 from which the locking rocker 6 can only emerge again after the over-dead center position shown in FIG. 1 has been overcome.
  • the pivoting movement of the locking rocker can be limited by approaches provided on the locking rocker 6 and interacting with the pressure body 2 and / or by approaches provided on the pressure body 2.
