Definitions

  • the present invention relates to a locking mechanism, in particular for a fan closure of an interior fan, consisting of a frame element with a frame opening, a closure flap with a closure path between an open and a closed state and at least one elastic Body, which at its to the middle of the frame opening to be closed directed end is firmly mounted on the frame opening, on this opposite end is positively guided and fastened to the closure cap, and its vertical distance between the two ends in the open state of the Closure flap is larger than the closure path, so that the elastic body Force in the direction of the closure path from a dimensionally stable state after exceeding one dimensionally unstable state into a second dimensionally stable Condition passes, the closure flap being opened when the shape is stable and in the other dimensionally stable state, the closure flap is closed.
  • the invention is based on the object of having a locking mechanism as few parts as possible and inexpensively in the simplest possible way realize.
  • the object is achieved in that the elastic body in closing state simultaneously seals the frame opening to be closed
  • the elastic Body has a rotationally symmetrical shape, and a concentric mounting edge has, with which it on a fastening piece of a frame element is attached.
  • the elastic body also has a special advantage outer retaining edge to a cover plate in a particularly simple manner with the to connect elastic body. This enables the locking mechanism to move out only three parts, the elastic body itself, the cover plate and the Frame element to manufacture.
  • the cover plate serves to stabilize the closure flap and design purposes and possibly as a handle on one manual operation.
  • the elastic body is advantageously in cross section hyperboloid-shaped and has to be closed at its center End opposite the frame opening rounding in the direction of the closure path. This shortens the shutter travel and the transition from that one dimensionally stable state over the dimensionally unstable state to the second Dimensionally stable condition facilitated.
  • This shape also corresponds to a streamlined shape Design with particularly little air turbulence due to the Lock mechanism occur.
  • Another advantage is the elastic body Made of elastomer plastic so that it is particularly simple and inexpensive is to be produced.
  • a locking mechanism is set, in particular a fan closure, from a frame element 1 and one Flap 2 together.
  • the frame element 1 consists of, for example rectangular mounting frame 3, which is particularly round Frame opening 4 is provided, and a round attachment piece in particular 6, which by means of, for example, three holding struts 7 on the mounting frame 3 is attached.
  • the closure flap 2 consists of a preferably round one Cover plate 8 and an in particular hyperboloid-shaped elastic body 9, which is made of elastomer plastic for a special advantage.
  • the elastic Body 9 preferably has a circular cross section of the elastic body, central opening 11 and a circular in cross section of the elastic body inner mounting edge 12, by means of which it is attached to the mounting piece 6 of the Frame element 1 is attached.
  • the elastic body 9 also has an outer circular holding edge 13 with which the cover plate 8 on the elastic body 9 is attached.
  • a locking mechanism is in the closed state the flap 2 shown, in which the cover plate 8, the frame opening 4th closes.
  • FIG. 3 an elastic body is shown.
  • the outside, in the cross section of the elastic body circular holding edge 13 is used advantageously How to attach the cover plate 8.
  • the cover plate 8 stabilizes the Positive guidance of the connected end of the elastic body 9, which by the rotationally symmetrical design of the elastic body 9 is caused.
  • the wall of the elastic body 9 is hyperboloid-shaped designed, at the outer end of the hyperboloid-shaped area Rounding in the direction of the closure path X, to which the holding edge 13th the cover plate 8 connects. At the inner end of the hyperboloid area is followed by the fastening edge 12 with which the elastic body 9 on the Fastening nozzle 6 is attached.
  • FIG. 5 shows a longitudinal section of an elastic body 9 in his second, after acting in the direction of the closure path X sufficiently large force, stable shape.
  • the shape of the elastic body is approximately inverse to the shape of Fig. 4, with between the inner end of the in 4 hyperboloid-shaped area and the attachment edge 12 a kink occurs.
  • the elastic body of the Locking mechanism also consist of a flexible and elastic metal.
  • Another form of the elastic body is also possible, in which the Transfer from a dimensionally stable position to another dimensionally stable position Takes place.
  • the elastic body is a curved, flexible metal strip mentioned, the one-sided fixed storage and other positively driven Storage and with sufficient closure path in the opposite curvature turns.
  • the locking mechanism would also be in the form of a tilting mechanism conceivable, in which the closure path is arcuate.
