Definitions

  • the invention relates to a handrail according to the preamble of claim 1.
  • the support In a known handrail of this type (DE 72 40 898 U1), the support consists of a box-like hollow body which is provided on its top with a support surface and on its underside with a removable cover. When the cover is removed, fastening screws are available which are used to fasten the box to a wall or the like. In addition, with the cover removed, a fastening screw can be screwed in from the underside of the box through an elongated hole passing through the support surface into the handrail element to be assembled.
  • Such an assembly of handrail elements is not always sufficiently stable, especially if the handrail elements consist of tubular elements.
  • the associated fastening screws only protrude into comparatively short threaded bores penetrating the tube wall, so that the handrail elements cannot absorb large transverse forces, especially if they are made of plastic.
  • the invention has for its object the handrail of the beginning designated genus so that stable connections of the handrail elements are obtained both with the supports and with each other.
  • the handrail element 1 shows an inventive handrail element 1 in the form of a tubular element which has a longitudinal axis 2.
  • the handrail element 1 contains a hollow cylindrical metal tube 3 and a plastic sheathing 4 mounted thereon, which preferably also consists of a tube and has the same length as the metal tube 3.
  • a connecting element 5 is inserted into each of the two open ends of the metal tube 3 serving as receiving openings.
  • the handrail element 1 could also consist of a solid rod, the ends of which have end-side receiving openings for the connection elements 5.
  • Each connector 5 contains one in the pipe end inserted, cylindrical fastening section 6 with an outer diameter corresponding to the inner diameter of the metal pipe 3 and a mounting section 8 connected to the fastening section 6 along a circumferential shoulder 7.
  • the shoulder 7 has a height corresponding approximately to the wall thickness of the metal pipe 3, so that the largest outer diameter of the mounting section 8 corresponds at most approximately to the outer diameter of the metal tube 3.
  • the fastening section 6 is inserted into the metal tube 3 in such a way that the shoulder 7 rests against its front end face, and for example by means of indentations 9, which are formed in the metal tube 3 and protrude into a transverse bore 10 of the fastening section 6, in the direction of the longitudinal axis 2 immovably and fixed non-rotatably in the metal tube 3.
  • the mounting section 8 is essentially semi-cylindrical at its front end 11 so that it can form an assembly block together with a correspondingly designed front end 12 (FIG.
  • the front ends 11 and 12 each have in their flat, mutually facing sections a recess 16 (FIG. 1) and an extension 17 projecting beyond the longitudinal axis (2), as a result of which the front ends 11, 12 are given a hook-like shape .
  • the mounting sections 8, 14 each have a continuous transverse bore 18 for receiving a fastening screw 19 (FIG. 2).
  • a handrail element 20 which has a tubular, plastic arch element 21, in which a metal insert 22 is arranged, which is somewhat shorter than the handrail element 20 and has a threaded bore 23 at at least one end, into which a threaded bolt 24 is screwed, which is provided at one end of a cylindrical insert 25 with an outer diameter corresponding to the outer diameter of the fastening section 6.
  • the threaded bolt 24 can be screwed into the threaded bore 23 are secured against rotation by a cross pin, which is inserted into a transverse bore projecting through the threaded bolt 24 and the wall of the arch element 21 and the insert 22.
  • the insert 25 is stuck in a receiving opening at one end of a tube piece 28 made of a metal tube 26 and a plastic jacket 27, the other end of which receives a connecting element 5 according to FIG. 1.
  • the insert 25, like the end element 5, can be fastened in the metal tube 26 by means of transverse bores and indentations.
  • the other end of the handrail element 20 is either designed accordingly or simply terminated with a stopper 29.
  • a support 32 suitable for fastening the handrail elements 1, 15 to a wall 31 or the like can be seen in FIGS. 2 and 4.
  • the support 32 essentially has a lower part 33 and an upper part 34.
  • the lower part 33 is e.g. Made of flat iron and has a central portion 35, one of which is angled by approximately 90 ° leg 36 at one end and a leg 37 angled by approximately 135 ° at the other end.
  • the leg 37 has a center hole and on its back a flat mounting surface, which is used to rest on the wall 31.
  • the attachment to the wall 31 is e.g. by means of a fastening screw 38 projecting through the center hole and a dowel 39 (FIG. 4).
  • the upper part 34 is e.g.
  • the upper part 34 can be pushed onto the lower part 33 in such a way that, in an assembly state shown in FIG. 4, on the one hand the lower part 33 is completely received and covered by the upper part 34, and on the other hand the mounting surfaces of the lower and upper part lie in the plane of the wall surface.
  • the assembly is carried out in such a way that the longitudinal axis 40 projects obliquely upwards from the wall 31 and forms an angle of approximately 45 ° with the vertical.
  • the upper part 34 gives the support 32 its external appearance.
  • the upper part 34 serves to support the handrail elements 1 and 15.
  • it has a semi-cylindrical bearing surface 41 which, according to FIG. 4, is inclined upwards and is open on the outside, the radius of which corresponds essentially to the radius of the outer peripheral surfaces of the mounting sections 8 and 14 of the connecting elements 5 and which has an axis 42 (FIG. 2) which, in the mounted state, runs parallel to the wall 31 and essentially horizontally.
  • the support surface 41 is provided with a center hole 43 and arranged at a preselected distance from the mounting surface.
  • the upper part 34 also has at its lateral ends recesses 44 which are adapted to the outer cross sections of the handrail elements 1, 15 or the plastic casing 4 and are therefore semi-cylindrical in the exemplary embodiment.
  • the recesses 44 are dimensioned such that they form stop or abutment surfaces for the adjacent end faces of the plastic sheathing 4 in the assembled state in the manner shown in FIG. 2 and have a width corresponding to their wall thickness.
  • the assembly of a handrail using the described supports 32 can be carried out as follows.
  • the lower parts 33 are fastened to the wall 31 by means of the fastening screws 38 and dowels 39 so that their central sections 35 protrude obliquely upwards in the manner shown in FIG. 4.
  • the upper parts 34 are then pushed onto the lower parts 33 in the manner shown in FIG. 4 until their mounting surfaces also lie against the wall 31.
  • the underside of the support surface 41 or stiffening webs connected to it are then preferably supported on the upper side of the leg 36.
  • two handrail elements 1 and 15 with the mutually assigned ends 11 and 12, ie with mounting sections 8 pivoted through 180 ° about the longitudinal axis 2 are placed on the support surface 41 from above, forming a mounting block (cf. also FIG. 2).
  • the arrangement is preferably such that the longitudinal axis 2 is arranged coaxially to the axis 42 (FIG. 2) of the semi-cylindrical bearing surface 41 in the assembled state.
  • the handrail elements 1, 15 are fastened to the support 32 by means of the fastening screw 19 inserted from above through the transverse bores 18 (FIG. 1) and the center hole 43, which simultaneously fastens the upper part 34 to the lower part 33.
  • a threaded hole in the leg 36 is used, for example, to tighten the fastening screw 19.
  • a press-in nut 45 can be used be provided, which receives the fastening screw 19 and is fixed in a center hole of the leg 36.
  • the fastening screw 19 could also be screwed into a normal nut arranged on the underside of the leg 36.
  • the position of the cross bores 18 in the mounting sections 8 and 14 is selected so that with coaxial alignment of both cross bores 18, the end faces of the handrail elements 1, 15 automatically rest against the stop surfaces formed by the recesses 44 (FIG. 2).
  • additional caps 46 (FIGS. 2, 4) are provided, which in the exemplary embodiment are semi-cylindrical and have an outer diameter which corresponds exactly to the outer diameter of the plastic sheathing 4.
  • cover caps 46 are fastened, for example, by means of internal snap connection elements 47 to the wall parts forming the support surface 41 and are designed to be so long that, in the assembled state (FIG. 2), along hair-thin butt joints, they protrude from the supports 32 protruding from the supports 32 of the plastic sheathing 4 of the handrail elements 1 , 15 as well as to the front and back of the upper parts 34 and form a flush continuation of their surfaces. This creates, at least from a distance, the impression that the entire handrail consists of an uninterrupted tube or rod element which is connected to the support 32 in a manner that is not visible.
  • the upper part 34 has a e.g. rectangular recess 48, which can be closed with a cover 49, which is also fastened to the upper part 34 by means of snap or snap connection elements 50.
  • the cover 49 preferably borders along the hairline butt joints to the upper part 34, so that it is hardly visible from the outside.
  • the cover 49 serves on the one hand the purpose of allowing access to the fastening screw 38 and / or to a nut which can be screwed onto the fastening screw 19, regardless of whether the upper part 34 is arranged on the lower part 33 or is connected to it to form a preassembled unit. On the other hand, the cover 49 can also be removed in order to expose the cutout 48 and to enable an additional fastening of a wall protection element or other components.
  • the press-in nut 45 is fastened to form a preassembled unit in the center holes of both the leg 36 and the stop surface 41.
  • the recess 48 allows access to the fastening screw 38 when fastening this unit to the wall 31.
  • the handrail element 20 can also be mounted on one side of the support 32.
  • the plug 29 can either be arranged near the wall 31, as is sometimes desired at the end of a handrail, or can be replaced by a further piece of pipe 28 with a connecting element 5, e.g. it is necessary to guide the handrail around a wall corner or the like.
  • FIG. 5 it is provided that the right handrail element 15 or its mounting section 14 in FIG. 2 is only assigned a loose mounting section 52 which replaces the mounting section 8 in FIG. 2 but is not connected to a fastening section 6 or another handrail element .
  • the opening that remains free on one side of the support 32 is closed by means of a latchable cap 53.
  • a handrail end can also be realized without the handrail element 20 according to FIG. 3.
  • connection elements 55 are provided, the fastening sections 56 of which consist of threaded bolts. These are screwed into hollow cylindrical, conically shaped expansion parts 57 with corresponding internal thread sections, which are arranged in expandable parts 58, which have expandable segments that lie against the inner jackets of the metal tubes 3.
  • the threaded bolts 56 are tightened in the expansion parts 57, they are axially displaced, thereby expanding the expandable parts 58 radially and fixing them in the metal tubes 3 by clamping action.
  • Expanding parts 57 and expandable parts 58 of this type are known per se (DE 40 30 978 A1) and therefore do not need to be explained in more detail.
  • the handrail shown in Fig. 7 contains massive wooden handrail elements 60 which are attached to have receiving openings 61 at their ends.
  • receiving sleeves 62 are fastened, which are provided, for example, with self-tapping external thread parts 63 and have internal thread sections which, analogously to FIG. 6, serve to receive threaded bolts which form fastening sections 64 of connecting elements 65.
  • FIGS. 5 to 7 are designed analogously to those according to FIGS. 1 to 4, which is why the same reference numerals have been used throughout for the same parts.
  • the invention is not limited to the exemplary embodiments described, which can be modified in many ways. This applies e.g. with regard to the axes 2 and 42 (FIG. 2), since exemplary embodiments are also conceivable in which the supports are used to mount the handrails of stairs and therefore do not run perpendicular to the longitudinal axis 40 (FIG. 4) and support surfaces 41 and Axles 42 could have. Furthermore, in FIGS. 1 to 7, the cutout 48 can also be located at another suitable location, if it is required at all, and the contact surfaces 41 could also be positioned differently, in particular relative to the cutouts 48.
  • the supports 32 or the lower and upper parts 33, 34 forming them with the support surfaces 41 are only one exemplary embodiment, especially since the support itself could also be designed as a one-piece hollow body.
  • the various features can also be used in combinations other than those described and illustrated.
