Definitions

  • the invention relates to a fastening device for a tubular handrail part.
  • Stairs are particularly for older people, the disabled but also a significant accident risk.
  • stairs are therefore increasingly often an additional second handrail (so-called wall handrail) attached to both sides.
  • wall handrail For publicly accessible buildings, it has even been required by law that staircases on both sides be provided with handrails that are sure to be secure and that must be routed over landings and window openings as well as over the last step.
  • flexible handrail systems are already offered, which can be assembled from individual elements and assembled quickly and easily.
  • a handrail of wood, plastic or metal tubes are put together, which are particularly connected to each other at corners or transitions by special transition or intermediate pieces.
  • a fastener for a pipe which includes an arranged between two guide discs elastic insert element and a clamping element, by means of which the outer diameter of the insert element can be enlarged by squeezing.
  • the clamping element contains a clamping screw with a central threaded hole and an associated nut.
  • the object of the invention is to provide a fastening device of the type mentioned, which allows a simple yet secure installation.
  • a significant advantage of the fastening device according to the invention is that a handrail can be mounted directly to the staircase without complex measuring and without special preliminary work with simple steps.
  • the existing wood, plastic or metal pipes must be cut only to the desired length, the fastener inserted and fixed.
  • a ball joint or other suitable connector is screwed into the fastener and used for connection.
  • About the fasteners differently shaped terminations or end caps can be attached to the pipe beginning or the pipe end. The assembly can be done at short notice without special manufacturing and assembly procedures.
  • a further advantage of the embodiment according to the invention is that an automatic alignment of the fastening elements takes place when they are inserted into the pipe end.
  • the two guide discs whose outer diameter is only slightly smaller than the inner diameter of the tubes, ensure that the fastener can not tilt to the side when inserted into the tube end, so that the central threaded hole is always aligned coaxially to the tube. This considerably simplifies the installation of a handrail.
  • Two or more annular or sleeve-shaped insert elements made of an elastomer, preferably rubber, are provided between the two guide disks. This allows a good frictional retention of the fastener can be achieved within the tube. Between the insert elements also one or more further guide discs can be arranged.
  • the fastening element shown schematically in the drawing comprises two annular or sleeve-shaped insert elements 1 and 2 made of an elastic material, the outer diameter for use in a bore or a tubular part of a handrail adapted to the inner diameter.
  • the insert elements 1 and 2 which consist of an elastomer, preferably rubber or a similar elastic material, are prestressed in the axial direction by a tensioning device.
  • the clamping device comprises a provided with an external thread 3 clamping screw 4 with a screw head 5, a nut 6 and two dimensionally stable guide discs 7 and 8, between which the two insert elements 1 and 2 are arranged.
  • the screw head 5 of the clamping screw 3 is designed as a cylinder head with a hexagon socket 9 for tightening the clamping screw 3.
  • the screw head 5 can be correspondingly, e.g. also be provided with an external hexagon.
  • the two guide discs 7 and 8 with the annular or sleeve-shaped insert elements 1 and 2 located therebetween are placed on the clamping screw 4 and clamped between its screw head 5 and the nut 6.
  • the clamping screw 4 extends a central threaded bore 10, in the e.g. a threaded pin of a termination element or a e.g. designed as a ball joint connecting part for connecting two tubular handrail parts can be screwed.
  • the outer diameter of the two preferably made of metal guide discs 7 and 8 is chosen such that it is only slightly smaller than the inner diameter of the tubes or holes into which the fastener is inserted. This ensures that the fastener when plugging into the pipe or the bore can not tilt sideways. This also automatically automatically located in the mounting screw threaded hole for attaching the connection or termination parts aligned coaxially to the pipe, making installation much easier.
  • the nut 6 is suitably rotationally connected to the guide disc 7. This can ensure that the nut 6 does not rotate when tightening the screw 5.
  • the rotation of the guide plate 7 is namely by the high friction when tightening on the rubber or similar. existing annular insert prevents.
  • the nut 6 may be formed integrally with the guide plate 7.
  • In the guide disc 7 may also be provided a suitable recess whose contour corresponds to the shape of the nut. But between the nut 6 and the guide plate 7 can also be arranged a toothed ring or other suitable anti-rotation. Also in the guide disk, the mother can be provided.
  • the diameter of the annular or sleeve-shaped insert elements 1 and 2 is selected such that they can be inserted in the uncompressed state with a small radial clearance in a pipe.
  • the two annular insert elements 1 and 2 are compressed in the axial direction, wherein they expand radially and create the inner wall of the tube.
  • the fastener is then held firmly under friction and safely within the tube.
  • Through the two guide discs 7 and 8 tilting within the tube is prevented, so that the provided in the clamping screw 4 threaded bore 10 is aligned coaxially with the tube.
  • a threaded pin of a connecting or end part can be screwed into the fastening device without problems. No elaborate alignment is required.
  • the invention is not limited to the embodiment described above. Thus, more than two insert elements can be provided instead of the two insert elements.
