Definitions

  • the invention relates to a clamping device for connecting two components, each having a flange in its end region.
  • An example of such a component are ventilation ducts.
  • Such components are interconnected in such a way that the outwardly directed flanges, usually of the same size, bear against one another and that the inner sides of the flanges facing away from the respective other component are exposed. This makes it possible to attack on these insides and brace the two flanges against each other so or jammed.
  • a clamping bracket is already known (DE 3309965), which consists of an actual bracket and a clamping lever.
  • the clamp can be slid onto the abutting flanges from the outside, and after pushing, a clamping force is generated by moving the clamping lever, which presses the two flanges against each other.
  • This clamp is expensive to manufacture and expensive to assemble.
  • the invention is based on the object, a clamping device for Establishing two each having a flange exhibiting components, which is easy to install, inexpensive to manufacture and easy to use.

  • the invention also proposes a fastening arrangement with two components abutting one another with their flanges and at least one clamping device according to claim 1. Further developments of the invention are the subject of dependent claims.
  • a separate element for generating the clamping force.
  • a bearing block For engagement with the side facing away from the respective other flange inside of a flange, a bearing block is provided, which optionally consists of a softer material and distributes the force over a larger area.
  • the element serving to generate the force may in particular be a substantially U-shaped element, in particular a spring clip, in which the two legs each serve to generate an inwardly directed force, the clamping force.
  • a suitable material and a suitable shape can be selected.
  • the support point, with which the clamping device is supported on one of the two components, may be formed by a bearing block or formed on the spring clip itself, for example on one of its legs.
  • the clamping device always has at least one contact block.
  • the clamping device has two contact blocks, each of which is suitable for a flange. is constantly, in which case a support point for the spring clip is formed at each investment block.
  • the two bearing blocks are identical or symmetrical to each other, so that when applying the clamping device does not need to be paid attention to the correct orientation of the clamping device.
  • At least one bearing block is guided displaceably on the spring clip. This ensures that after attaching the bearing block to the flange, the spring clip can be pushed onto the bearing block, in order to transmit the spring force to the contact block.
  • the bearing block in addition to its contact surface for the inside of the flange has a further contact surface, which limits its postponement or its movement from the edge of the flange in the direction of the component itself.
  • This contact surface which preferably cooperates with the edge of the flange, is particularly useful when the clip is pushed onto the plant block.
  • the bearing blocks are connected to the spring clip such that their outer sides diverge from the spring clip. Since the outer sides extend at least approximately parallel to the contact surfaces of the respective contact block, in this way it is ensured that the clamping force increases as the clamping device is pushed deeper.
  • the spring clip forms with the two investment blocks a kind of open pliers, which facilitates the sliding of the clamping device on the two flanges and allows.
  • the spring clip may be formed in a further development of the invention, in particular, that it comprises two approximately parallel legs, which are interconnected by a web.
  • a notch is formed between the two contact surfaces of each contact block. This makes the clamping device also suitable for such flange connections in which a widening of the flange is still formed on the edge of the flange.
  • a defined end position can be formed by the fact that the web of the spring clip comes to rest on the edge of the flanges.
  • the spring derklammer For fixing a bearing block to the spring clip, the spring derklammer have an opening through which passes through a pin of the investment block. In order to allow a displacement of the bearing block relative to the spring clip, this opening may be a slot.
  • Figure 1 is a side view of a spring clip as part of the clamping device according to the invention.
  • Figure 2 is the view of the spring clip from the right in Figure 1;
  • Figure 3 is a perspective view of the spring clip

  • FIG. 9 shows the view of the clip of FIG. 8 from the left in FIG. 8.
  • Figure 1 shows a spring clip, which is made of a spring steel.
  • the spring clip 1 includes a flat web 2, which is bent in the region of its two ends in the same direction and there forms two legs 3, which extend approximately at right angles to the direction of the web 2.
  • the free ends 4 of the two legs 3 are bent diverging outwards.
  • the length of these bent ends 4 of the two legs 3 is about 1/5 to 1/4 of the length of the legs. 3
  • a slot 5 is formed in each case, which has a closed circumference.
  • Each slot 5 extends at one end almost to the web 2, and extends at the opposite end to the divergent end 4.

  • the pins 8 abut the ends of the slots 5 facing away from the web 2.
  • Both the outer sides 7 and the contact surfaces 9 diverge from the spring clip 1 starting.
  • the clamping device is approximated to the end of the two flanges 15 until the connecting band 12 rests on the common edges 16 of the two flanges 15. These are the flanges 15 of two ventilation duct plates.

Again, the two bearing blocks 26 are attached to the end portions of the two legs 23 of the spring clip 21, by means of a film hinge 24. They are thus made in one piece together with the spring clip 21.
  • Such a spring clip as shown in FIGS. 8 and 9, can be produced very inexpensively by injection molding.
  • a bead 22 is formed on the outside of the spring clip 21 for reinforcement, so that the spring clip actually has a greater thickness and thus greater strength.
  • the film hinges 24 can tear off, and the protection against slipping can be improved by the teeth on the inner sides 25 of the legs 23 and on the outside of the bearing blocks 26.
  • the clamping device of FIGS. 8 and 9 may alternatively be produced by the zinc die-casting process, that is to say consist of zinc, or else be cast of steel (MIM process). These metal clamps may be advantageous in special cases for fire safety reasons.
  • the clamping device described herein is primarily intended to clamp parts of ventilation ducts together.
  • the clamping device according to FIGS. 5 and 6 for fixing the flanges of two components which extend parallel to one another with their end faces comprises two contact blocks which are symmetrical to one another and are preferably made of relatively hard plastic, which have two contact surfaces.
  • One abutment surface is intended to abut against the other component facing away from the inside of the flange, the other contact surface, which runs approximately perpendicular thereto, limits the postponement of the bearing block on the flange of the edge thereof.
  • the two blocks which are connected by a thin band, are placed on the two flanges from the edge, pushed and fixed by means of a spring clip.

Abstract

L'invention concerne un dispositif de serrage destiné à solidariser les brides de deux pièces dont les surfaces d'extrémité sont parallèles entre elles. Le dispositif comprend par exemple deux blocs d'appui (6) configurés symétriquement l'un à l'autre, fabriqués de préférence dans une matière plastique relativement dure et possédant deux surfaces d'appui (9). L'une des surfaces d'appui (6) est destinée à s'engager contre le côté intérieur (19) de la bride (15) qui est opposé à l'autre pièce. L'autre des surfaces d'appui (6), qui est sensiblement perpendiculaire à la première, empêche le déplacement du bloc d'appui (6) sur la bride (15).
