Definitions

  • the invention is concerned with the formation of latching brackets, in particular with the production of such grid brackets, which of material tolerances the objects connected by means of the grid holder largely are independent.
  • the spring tongues shaped are that on the one hand with the participation of storage means on a projection rest and that the free ends of the spring tongues on free Place the end faces of the protrusions when the one carrying the loudspeaker Carrier is inserted into an opening in a baffle.
  • a radial concern of the free ends of the spring tongues on the end face of the projections is thereby achieved that there are wedge-shaped lugs on a cover, which, if they are inserted into the openings next to the projections, which move free ends of the spring tongues in the direction of the end faces and wedge.
  • the nasal products would be separate Components act, since these often do not belong to the construction components are connectable or in cases where a connection with others, structurally necessary components is possible because of such a connection the costs caused by the high dimensional accuracy of the noses for reasons the economy is eliminated.
  • the invention has for its object to provide a locking bracket which is formed in one piece and an airtight connection between the connected objects allowed without great demands on the Dimensional accuracy of the connected parts.
  • the spring tongues are designed according to claim 1, it is possible by a corresponding pressure effect on the end faces of the noses, the To transfer clamping edges or spring tongues into their target position if object placed on the bearing means, in the spring tongues stored restoring forces, for example for reasons of tolerance deviations, not enough to move the spring tongues into their target position. Because the noses with such a deviation of the spring tongue from the jacket wall emerge from the hollow body, it is impossible, for example, the hollow body with an object that is not yet fully locked into an installation opening insert or push on a mandrel. Because not yet completely made snap connection the lugs from the jacket wall of the Stepping out of the hollow body can be done very easily by visual inspection Mis-locking can be determined and remedied. The latter, for example, in that a tool is guided along the side of the jacket wall. Are the Providing the front sides of the noses with appropriate ramps can do that along the tool at the same time as the along Eliminate incorrect locking.
  • the distance between the storage means and Clamping edges related to the thickness of a snapped object chosen that with an object pushed onto the storage means Spring tongues have not yet given their position before snapping have put on hold, so the snap is still incomplete, they can end faces protruding from the jacket wall can be used for the until then only complete incomplete rest connection and the Secure positive locking additionally by means of a frictional connection. To it is necessary that a corresponding pressure force acts on the end faces. Furthermore, the frictional connection contributes to the fact that the locked object does not Carry out radial movement between the clamping edges and the bearing means can. In addition, tolerance deviations with regard to the thickness of the locking object uncritical, because of the force acting on the End faces the spring tongues in each case assume their desired position or in this be transferred.
  • the openings in the jacket wall when the Spring tongues have assumed their target position by a cover element closed so it is impossible for the noses from the jacket wall to emerge, so that even considerable force effects on locked objects cannot break the locking connection. It is very beneficial in this context when the cover elements are formed by one component with which the hollow body carrying the latched object later is connected.
  • the elongated hollow body 10 which is essentially formed by a casing wall 11, has the cross section of a circular ring.
  • a shoulder 12 is arranged as a bearing means, which runs transversely to the direction of extension of the hollow body 10 and extends into the interior of the space 13 surrounded by the jacket wall 11.
  • this end of the hollow body 10 has a flange 15 connected to the outside 14 of the hollow body 10.
  • two spring tongues 17 are arranged, which are spread apart from the jacket wall 11.
  • openings 19 are provided in the region of the jacket wall 11, to which the spring tongues 17 run at a radial distance from this. These openings 19 are penetrated by lugs 20 which are connected to the spring tongues 17.
  • the end faces 21 of the lugs 20 point in the opposite direction with respect to the direction of extension of the shoulder 12. If an object 22, which is shown in broken lines in FIG. 1 for reasons of clarity, is now to be inserted into the hollow body 10 and connected under the action of the spring tongues 17, it is necessary that the area of the object 22 which is between the clamping edge 18 and the shoulder 12 is to be held, has a larger cross section than the cross section formed by the relaxed spring tongues 17.
  • Fig. 1 corresponds optimal conditions, This means that after the object 22 between the Clamping edges 18 and the shoulder 12 is arranged, the spring tongues 17 again their debit position, that is, the position they take before inserting the Had item 22. But is that between the clamping edge 18 and Shoulder 12 arranged area of the article 22 slightly thicker than provided or is that stored when inserted in the spring tongues 17 Low energy, so take the spring tongues 17 during their rebound movement contrary to the direction of the arrow P2 no longer their target position on the object 22 a.
  • FIG. 2 shows an embodiment in which the spring tongues 17 for Outside 14 of the hollow body 10 are spread apart.
  • the shoulder 12 attached to the outside 14.
  • This hollow body 10 is in a Installation wall 23 used, only in the state shown in Figure 2 outer part of each clamping edge 18 abuts the installation wall 23. this will achieved in that the thickness of the mounting wall 23 is slightly larger than that smallest distance between the clamping edge 18 of a spring tongue 17 in the desired position and the shoulder 12. Since the rag length of the noses 20 is dimensioned so that the spring tongues 17 in the desired position, the end faces 21 with the inside 16 of To close the hollow body 10 flush, start with the one shown in FIG. 2 always incomplete latching the lugs 20 on the inside 16 of the Hollow body 10 always out of the wall 11.
  • the openings 19 should be opposite the spring tongues 17 Conversion side (14 or 16) with appropriate cover elements be.
  • this cover element formed by a wall 26 in which is used the hollow body 10 locked with the object 22.
