Definitions

  • the invention relates to a tension-resistant connection between two components which adjoin one another on the end face and have an at least partially curved outer surface by means of a spring ring which connects the components in a frictionally locking manner.
  • Tension-resistant connections of the type mentioned at the outset are used in pipe connections, for example for running or guide rails in the sanitary area, in particular in shower systems, in corner connections for railings or the like or in the tensile connection of a door handle to a handle pin.
  • a device of the aforementioned type is disclosed in US Pat. No. 3,345,103, which relates to the attachment of a door handle to a handle pin that grips the door.
  • a C-shaped, slotted spring clip is inserted into a stepped blind hole in the pusher neck, the pusher pin engaging through an opening in the spring clip corresponding to the outer contour of the pusher pin and being held on the spring clip in such a friction-locking manner by means of tongues arranged on the spring clip that the spring clip is held on it Assignment of a grub screw that grips the pusher neck and can be adjusted against the pusher pin can be dispensed with.
  • the tongues arranged on the spring clip run in the direction of the bottom of the blind bore, so that they counteract the pull-off direction of the trigger neck.
  • an additional, externally toothed washer which is adjacent to the spring clip, is required. whose teeth are frictionally supported on the inner wall of the blind bore of the pusher neck.
  • the pusher pin is secured against rotation in the pusher neck by engaging the pusher pin in an additional step of the blind hole.
  • the object of the invention is to provide a technically simple means, a tensile connection between two components of the type mentioned, in which both on a complex stepped bore in one of the adjacent components and on the assignment of an additional, the spring clip or spring ring against axial displacement locking locking member can be dispensed with.
  • the spring washer is secured in the groove against axial displacement, ie even larger forces acting on the spring washer in the axial direction of the connection cannot lead to an axial displacement of the spring washer.
  • the device according to the invention can also be used to produce tension-resistant connections in the case of components which adjoin one another on the end face and which are not circular in cross section but only have an arcuate, ie convex, contour over part of their circumference.
  • the storage of the spring washer in the groove allows, depending on the design of the groove depth with respect to the spring ring, the choice of a highly elastic material, the hardness of which can be greater than that of the material of the components to be connected, with the choice of the groove depth used for the spring ring - Deteten material and the strength of the spring ring on the the spring ring comprehensive component exerted contact pressure can be determined in individual cases, so that ultimately the releasability of the basically tensile connection can be influenced.
  • An additional influence on both the tensile strength and the releasability of the connection enables the design of the projections which can be connected to the tubular wall of the second component in a frictionally locking manner.
  • the projections arranged on the outer casing of the spring ring consist of barbs which can be frictionally adjusted against the inner casing of the tubular wall of the second component, the tips of the barbs lying against the inner casing of the second component being arranged so as to point towards the pull-off direction.
  • Such an embodiment brings about a sufficiently tensile connection and is particularly useful when connecting adjoining profile tubes, ie. for pipes with a non-circular cross-section, suitable because the non-circular cross-section prevents the neighboring pipes from twisting.
  • the alignment of the tips of the barbs against the pulling direction makes pulling difficult, especially when the material of the spring ring has a greater hardness than the material of the components to be connected.
  • the projections> of the spring ring which can be connected to the tubular wall of the second component can be pins which engage in recesses in the second component, the design of the pins - for example as a flat semicircular knobs - being one Detachability of the connection enables, in particular if there is sufficient play between the inner jacket I of the spring ring and the groove base of the groove.
  • projections which can be connected in a frictionally locking manner to the outer wall of the spring ring with the tubular wall of the second component and projections which can be connected in a frictionally locking manner to the groove base of the groove are arranged on the inner surface of the spring ring , wherein the projections arranged on the inner surface of the spring ring are preferably barbs which can be adjusted in a frictionally locking manner against the groove base of the groove, and the barbs which bear against the groove base are alternately arranged in the circumferential direction and directed towards one another.
  • the projections of the spring ring which are arranged on the inner surface of the spring ring and can be connected to the groove base of the groove, can be pins which engage in recesses in the groove base; since the spring ring remains in the groove when the connection is released, the aforementioned pin connection can be designed such that the spring ring can be pulled apart from the groove after the two components have been released.
  • the invention explained above is fundamentally suitable for the connection of components which adjoin one another on the end face, provided that they have at least a partially curved outer surface, ie for example also for the end closure of a round tube or profile tube by means of an end cap delimiting the end faces of the tubes. It is only necessary to assign an extension to one of the two components, in which the aforementioned groove receiving the spring ring is arranged, the extension preferably being solid and the spring ring consisting of a suitable stainless steel.

  • the tips 18 of the inner barb 17 lie against the groove base of the groove 11, not shown, and prevent the spring ring 4 from rotating relative to the shoulder 10.
  • the exemplary embodiment according to FIGS. 5 to 9 differs from the exemplary embodiment according to FIGS. 1 to 4 by the use of a non-circular tube, referred to as profile tube 8, FIG. 5 showing the connection with the fastening support 5 and FIG. 6 showing the connection with an end cap 6 ,
