Definitions

  • the present invention relates to a locking mechanism, in particular for a fan closure of an interior fan, consisting of a frame element and a Closure flap with a closure path between one open and a closed state.
  • the invention is based on the object of a locking mechanism with as few parts as possible and on as possible simple way to implement inexpensively.
  • the Locking mechanism at least one elastic body owns, which is to be locked at its center Opening directed end is fixed and on its positively opposite end, and the length of which is greater than that perpendicular to the closure path Distance between the two ends of the body, so that the elastic Body when force is applied in the direction of the closure path from a dimensionally stable state after exceeding of a shape-unstable condition into a second shape-stable one Condition passes, with a dimensionally stable Condition the flap is open and the other dimensionally stable condition the flap is closed.
  • the mechanism described above becomes self-exposure of the elastic body in the respective dimensionally stable condition reached. So there are no additional ones Locking agent necessary. It is an advantage if the elastic body has a rotationally symmetrical shape has, and has a concentric mounting edge, with which he attached a mounting bracket Frame element is attached. A special advantage the elastic body also has an outer one Holding edge around a cover plate in a particularly simple manner to connect with the elastic body. This makes possible the locking mechanism from only three parts, the elastic body itself, the cover plate and the Frame element to manufacture.
  • the cover plate serves here the flap stabilizing and design Purposes and sometimes as a handle on a manual Activity.
  • the elastic body is advantageously in the Cross section formed hyperboloid and has on his opposite to the center of the frame opening to be closed End rounding in the direction of the closure path. This shortens the closure path and the transition from the one dimensionally stable state to the dimensionally unstable State to the second dimensionally stable state facilitated.
  • This shape also corresponds to a streamlined shape Design with particularly little air turbulence occur through the locking mechanism.
  • the elastic body made of elastomer plastic manufactured so that it is particularly simple and is inexpensive to manufacture and shaped and positioned that when it is closed it is also a seal between the frame opening and cover plate.
  • an inventive method is used Locking mechanism, in particular a fan lock, from a frame element 1 and a flap 2 together.
  • the frame element 1 consists of, for example rectangular mounting frame 3, with a in particular round frame opening 4 is provided, and a particularly round attachment piece 6, which by means of, for example, three holding struts 7 on the mounting frame 3 is attached.
  • the closure flap 2 is made from a preferably round cover plate 8 and one in particular hyperboloidal elastic body 9, which has a special advantage made of elastomer plastic consists.
  • the elastic body 9 preferably has a Cross section of the elastic body circular, central Opening 11 and one in cross section of the elastic body circular inner mounting edge 12, by means of which it attached to the mounting piece 6 of the frame member 1 becomes.
  • the elastic body 9 also has an outer circular holding edge 13 with which the Cover plate 8 is attached to the elastic body 9.
  • Fig. 3 is an elastic body according to the invention shown.
  • the outside, in cross section of the elastic body circular holding edge 13 is more advantageous 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.
  • Fig. 4 shows a longitudinal section of an inventive elastic body 9 in its original, at the Manufactured, stable shape.
  • the wall is elastic Body 9 designed hyperboloidal, with the outer end of the hyperboloid-shaped area is rounded is in the direction of the closure path X, on the the holding edge 13 of the cover plate 8 connects.
  • the end of the hyperboloid-shaped area closes Attachment edge 12 with which the elastic body 9 on the attachment piece 6 is attached.
  • Fig. 5 shows a longitudinal section of an inventive elastic body 9 in its second, after exposure one acting in the direction of the closure path X is sufficient great strength, stable shape.
  • the shape of the elastic body is roughly inverse to the shape Fig. 4, between the inner end of the in Fig.4 hyperboloid-shaped area and the fastening edge 12 a kink occurs.
  • the elastic body the locking mechanism also from a flexible and made of elastic metal.
  • the elastic body there is also another one Form of the elastic body, possible, in which the turning over from a stable position to another dimensionally stable position would be conceivable.
  • a curved flexible metal strip mentioned that at single-ended fixed storage and other positively driven Storage and with sufficient closure path in the opposite Curvature turns.
  • the locking mechanism would also be conceivable in the form of a tilting mechanism in which the shutter path is arched.
