Definitions

the invention relates to a fastening element for a pipe, in particular a handrail, according to the preamble of claim 1.
Staircases make a significant contribution, especially for the elderly, disabled but also children Accident risk.
an additional second handrail (so-called. Wall handrail) attached to the two-sided bracket.
Wall handrail For publicly accessible buildings It has even been required by law that stairs are secure on both sides Handrails are received over landings and window openings as well as over the last step are to lead.
flexible handrail systems are already being offered that consist of individual elements assembled and assembled quickly and easily.
one Handrail made of wood, plastic or metal tubes are put together, the most at corners or transitions through special transition or intermediate pieces together get connected. To do this, e.g.
the object of the invention is to provide a fastener of the type mentioned create a simple yet secure installation.
a significant advantage of the fastener according to the invention is that a Handrail without elaborate measuring and without special preparatory work with simple Handles can be mounted directly on the stairs.
Made of wood, plastic or metal existing pipes need only be cut to the desired length, the Fastening element inserted and fixed.
To connect with another Pipe piece can then subsequently be e.g. a ball joint or another suitable one Connector screwed into the fastener and used for connection become.
About the fasteners can also be on the pipe beginning or the pipe end differently designed terminations or end caps are attached. The assembly can take place at short notice and without special manufacturing and assembly procedures.
Another advantage of the embodiment according to the invention is that an automatic Orientation of the fasteners 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 is to ensure that the fastener when inserting in the pipe end can not tilt to the side, so that the central threaded hole always aligned coaxially with the tube. This makes the installation of a handrail considerably simplified.
one or more ring or sleeve-shaped insert elements provided between the two guide discs.
the Insert elements are expediently made of an elastomer, preferably Rubber. This allows a good frictional retention of the fastener within of the pipe can be achieved. With two or more insert elements can between this also be arranged one or more further guide discs.
the fastening device shown schematically in the drawing contains two ring or sleeve-shaped insert elements 1 and 2 made of an elastic material whose Outer diameter for use in a bore or a tubular part of a handrail adapted to the inner diameter.
Made of an elastomer, preferably rubber or a similar elastic material existing insert elements 1 and 2 are through a clamping device biased in the axial direction.
the clamping device comprises a clamping screw 4 provided with an external thread 3 with a screw head 5, a nut 6 and two dimensionally stable guide disks 7 and 8, between which the two insert elements 1 and 2 are arranged.
the screw head 5 of the clamping screw 3 is a cylinder head with a Hexagon socket 9 designed to tighten the clamping screw 3.
the screw head 5 can but in a similar manner e.g. also be provided with an external hexagon.
the two Guide discs 7 and 8 with the intervening ring or sleeve-shaped Insert elements 1 and 2 are placed on the clamping screw 4 and between her Screw head 5 and the nut 6 clamped.
the clamping screw 4 extends a central threaded bore 10 into which e.g. a threaded pin of a closing 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 plates. 7 and 8 is selected to be only slightly smaller than the inner diameter of the tubes or holes into which the fastener is inserted. This will ensures that the fastener when plugging into the pipe or the bore can not tip over to the side. This will automatically in the Fixing screw threaded hole for attachment of the connection or End parts automatically aligned coaxially with the tube, thereby increasing assembly considerably is simplified.
the nut 6 is suitably rotationally connected to the guide disc 7. This can ensure that the nut 6 when tightening the screw. 5 does not rotate.
the rotation of the guide plate 7 is namely by the tightening high friction on the rubber or similar existing annular insert prevents.
the nut 6 may be formed integrally with the guide plate 7.
the Guide disc 7 may also be provided a suitable recess, the contour of the Form of the mother corresponds. 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 chosen such that that they are in the uncompressed state with a slight radial clearance in a pipe can be inserted.
the two annular insert elements 1 and 2 compressed in the axial direction, wherein they are radially expand and apply to the inner wall of the pipe.
the fastener is then held firmly under friction and safely inside the tube.
the two Guide discs 7 and 8 prevents tilting within the tube, so that the in the clamping screw 4 provided threaded bore 10 is aligned coaxially with the tube.
One Threaded pin of a connecting or final part can so easily in the Fastening device are screwed. It is not a complicated orientation required.
Insert elements are provided.
