Definitions

  • the invention relates to a wall mounting for a shower rail pipe of a shower system according to the preamble of claim 1.
  • Such a shower rail pipe is usually mounted in the vertical direction on an installation wall, namely at a predefined distance from the installation wall in the depth direction. To attach the shower rail pipe, this is connected to a bracket, which in turn is attached to the installation wall.
  • the shower bar pipe is connected to the console via a clamp that encompasses the shower bar pipe.
  • this creates two circumferential dirt edges per clamp, which extend over the entire circumference of the shower rail pipe. Dirt, such as shampoo and soap residues, easily collects in their area, which is difficult to remove in the area of the dirt edges.
  • the pipe ends should also be sealed watertight to prevent dirt from entering and to ensure that the shower rail pipe has a long service life. This usually works well with new shower systems. Over time, however, all parts installed in the shower system age and the watertightness of the closures of the shower rail pipe is no longer guaranteed. In addition, shampoo and soap residues, as well as water, collect in the interior of the shower rail tube due to the deterioration in water resistance. In known shower systems, it is not possible to clean the shower system in such a case with reasonable effort.
  • the object of the invention is to provide a wall fastening for a shower rail pipe, in which a fastening of the shower rail pipe to the installation wall is made possible in a durable and easy-to-clean manner.
  • the object is solved by the features of claim 1. Preferred developments of the inventions are disclosed in the subclaims.
  • the wall fastening has a mounting section which is arranged in the interior of the shower rail pipe and which is connected to the end cap and is screwed through a pipe wall of the shower rail pipe to the console, around the shower rail pipe on one side to the console to tie.
  • the end cap and the mounting section together form a multi-part component assembly, which makes it possible to choose a complex geometry both for the mounting section and for the end cap without complicating the manufacturing process of the wall fastening according to the invention.
  • the end cap and the mounting section can be made of different materials.
  • the mounting section on a side facing the bracket has a nut or a threaded insert which, in cooperation with a fastening screw, connects the mounting section through the inner wall of the shower rail pipe on one side to the bracket.
  • the mounting section has a first locking element with a first locking hook and a second locking element with a second locking hook, the first locking hook engaging in a corresponding first recess in the end cap and the second locking hook in a corresponding second one in the end cap around the end cap to be positively connected to the assembly section via a snap-in connection.
  • the end cap has a sleeve and a cover closing the sleeve on one side, the first recess and the second recess being introduced into an outer circumferential surface of the sleeve and the first latching element and the second latching element each having their latching hooks opposite Sides abut against a wall of the shower rail in order to prevent the locking elements from moving radially outwards in relation to the shower rail.
  • first latching hook and the first latching element have a first width bl and the second latching hook and the second latching element have a second width b2, the first width bl and the second width b2 having different amounts, and wherein the first recess is adapted to the width bl and the second recess to the width b2 in order to positively connect the end cap to the mounting section in a predefined orientation relative to the mounting section.
  • the mounting section has a height stop, in particular in the form of a tab, which engages in a groove in the end cap for a first mechanical play of the first locking element in the first recess and a second mechanical play of the second locking element in the limit second recess.
  • the mechanical play is limited in a direction parallel to a longitudinal axis of the shower rail pipe.
  • the mounting section on a side facing the console has a receiving space, in particular a conical or a flat countersink, which is arranged concentrically about an axis of the thread of the nut or of the thread of the threaded insert and which is radial with respect to the shower rail pipe extends inwards.
  • the receiving space is designed to receive a ridge in the area of the bore.
  • the mounting section on one side facing the bracket has an annular elevation, which is arranged concentrically around a bore axis of a bore in the shower rail tube and which extends radially outward with respect to the shower rail tube, the elevation in the bore in Centered shower rail pipe to fix the mounting section in its position and position relative to the shower rail pipe ren.
  • the cover has a positioning contour which engages in a complementary contour which is introduced into or attached to an end face of the shower rail pipe in order to hold the cover in a predefined orientation in a rotationally secure manner with respect to the shower rail pipe.
  • the notches or steps are introduced into the shower bar tube from the end face of the shower bar tube parallel to an axis of rotational symmetry of the shower bar tube.
  • One or more corresponding shoulders in the cover of the end cap engage in these notches or steps in order to prevent the end cap from rotating relative to the shower rail tube.
  • the mounting section has a support base connected to the mounting section via one or more spring elements or one or more material webs, each with an elastic extension, which presses a first region of the mounting section elastically against the side facing the inner wall of the shower rail pipe to press the first area of the assembly section radially outwards and in the direction of the fastening screw when screwing in the fastening screw in relation to the shower rail pipe.

  • the axis of rotational symmetry of the nut 32 and the bore axis of the bore 31 coincide with the bore axis 12.
