Definitions

  • the present invention relates to a clamp connection for a presentation frame with which goods can be presented in showrooms.
  • the invention relates to a clamp connection with which pipes and connecting elements can be assembled into racks in the form of shelves, showcases, cupboards and the like, the connection between the pipes and connecting elements being produced solely by clamping between pipe pieces and connecting elements without further securing elements becomes.
  • the invention further relates to
  • Presentation systems which are known as shelves, showcases, cupboards, tables or pedestals, for example from shops or other presentation rooms, such as exhibition stands, serve to attractively display various goods for the buyer or trade fair visitor.
  • the individual elements from which the presentation systems are to be constructed should be used as flexibly as possible, and should be able to be assembled quickly, since they are often only required for a short time in a configuration, and still ensure good cohesion, even when loaded.
  • the presentation systems can be manufactured inexpensively on the one hand due to the flexible use of different components and on the other hand due to the type of components. It is also required that the presentation systems create a visually appealing product carrier. State of the art
  • CH-A-454 555 a clamp connection is described which consists of a tube section with a square cross-section on the one hand and a counterpart which has the cross-sectional shape of a circular cylinder and is provided with four depressions or flats arranged offset by 90 ° to one another.
  • the essentially circular-cylindrical tube piece can be pushed into the square tube piece.
  • the essentially cylindrical piece of pipe is then rotated through 45 °, as a result of which the non-flattened areas enter into a clamping connection with the sides of the pipe with a square cross section.

  • a connecting element is connected to a pipe section via a clamp connection, a presentation frame being able to be produced by means of several such connections.
  • Spigots extend from the connecting element, which can be inserted into a pipe piece in a first position of the pipe piece for the spigot and can be brought into a clamping position with the spigot by twisting on the spigot.
  • the clamping zones are formed by transverse ribs, which lie between the radial knots running around the pin, and have an upper peak. Furthermore, the clamping zones fall down to the adjacent flats.
  • a device for screwless fastening of a pipe is known from DE 15 75 319 B, in which a sleeve with a regular polygonal outer cross-section is inserted into a pipe with a geometrically similar inner cross-section, the pins to be fastened to the pipe in turn having axial projections that the Correspond to the number of polygon sides, so that the axial pin projections in the fastening state of the sleeve interact with locking grooves which are arranged in the polygon sides of the sleeve interior and which face the polygon corners of the tube.
  • the invention has for its object to provide a clamp connection in which the strength of a connection is as high as possible, while still ensuring inexpensive manufacture. Finally, elements that secure the clamping connection and that disrupt the visual impression should be avoided.
  • the invention has for its object to provide a flexible presentation system that is versatile and inexpensive to manufacture.
  • the invention is based on the idea of improving the correct fit of the tube piece and the connecting element to one another in the clamping position by providing alignment aids.
  • the alignment aids are shaped in such a way that they have an adjustment surface which, in the clamped position, is parallel to one side of the pipe section and lies against this side, so that the side of the pipe section is supported accordingly over a surface and not just over a line. This largely prevents undesired twisting, since initially a higher force has to be applied when the clamping connection is released.
  • an adjustment surface in the sense of the invention can be realized not only by a continuous surface in the conventional sense, but also by other means, for example at least two appropriately positioned point-shaped elevations that define an adjustment plane that is not materially designed.
  • An adjustment plane in the sense described should therefore also be encompassed by the term “adjustment surface”.
  • Increased resistance also occurs during assembly and disassembly.
  • This necessity of applying an increased force can, however, be avoided by first placing the pipe section and the connecting element in the aligned position and then inserting them into one another parallel to the longitudinal pipe axis, so that the pipe section is aligned in the longitudinal direction on the alignment aids the connector is pushed on.
  • the advantages of a relatively simple and quick assembly are still guaranteed, whereby, of course, the conventional assembly route, that is to say first completely pushed on and then rotated into the clamping position, can also be selected.
  • the fit of the connecting elements and the pipe pieces to one another is improved and the connection is made more stable against unwanted twisting or slipping.
  • the alignment aids are in the assembled state, that is to say in the clamped state, within the pipe sections, they are not visible from the outside, so that an attractive appearance of a built-up frame or a similar presentation system is retained.
  • the polygonal cross section of the pipe section preferably has four corners, ie it is square. Other polygonal cross-sections (triangle, pentagon, hexagon ...) are also conceivable.
  • the square shape of the pipe section ensures on the one hand that a relatively good production of the connecting pieces is possible, since four clamping zones and four insertion zones are to be provided, which are used for production by z.
