Definitions

  • the invention relates to a handrail with a metallic and electrically conductive hollow profile that has at least one profile wall opening.
  • the handrail has, in its metal hollow profile, a slot-shaped profile wall opening running in the longitudinal direction, in which a lighting device with an LED is provided as an insert.
  • electrical inserts also meet electrical protection classes or insulation protection classes, this does not guarantee that these inserts are also suitable for handrails in a high-voltage environment.
  • broken high-voltage lines can cause significantly high electrical currents to flow for a short time, which can lead to high temperatures in the area of the profile wall opening of a handrail.
  • the invention has therefore set itself the task of changing the design of a handrail of the type described at the outset in such a way that it can be used in a stable manner even in a hazardous area with high voltage.
  • the handrail should be structurally simple and inexpensive.
  • the invention solves the problem set by the features of claim 1.
  • the hollow profile viewed in the longitudinal direction, has a recess with a first slot and a second slot before and/or after the profile wall opening, the courses of which diverge in a first longitudinal section of the recess from a common head end to the profile wall opening, it may be possible for the handrail to be able to conduct even high electrical currents, at least for a short period of time. Because of this cutout, the flow of current in front of the profile wall opening can be advantageously influenced, which, for example, avoids singularities in this area, which are essentially responsible for thermal hotspots or electrical flashovers. Electrical and/or thermal overload in the area of the profile wall opening can thus be avoided. The risk of the insert melting or burning in the profile wall opening is thus reduced, which always ensures the function of the handrail, namely guiding people safely out of a danger area.
  • the first and second slots end in front of the profile wall opening with a longitudinal spacing in order to be able to further ensure the mechanical stability of the handrail in the area of the profile wall opening. An impairment of the guide function of the handrail is therefore not to be expected.
  • the profile wall opening has a maximum opening width transversely to the longitudinal direction of the hollow profile, and if the courses of the first and second slot essentially diverge towards this opening width, this can further reduce the risk of an electrical and/or thermal overload of the insert.
  • the flow of current in the handrail can be adjusted further in an improved manner in the area of the profile wall opening if the first longitudinal section is adjoined by a second longitudinal section of the recess, in which second longitudinal section the courses of the first and second slots converge from the first longitudinal section to the profile wall opening
  • the flow of current in the handrail can be adjusted to a tapering in the line cross-section due to the profile wall opening, which is further improved if the first longitudinal section is adjoined by a second longitudinal section of the recess, in which second longitudinal section, the courses of the first and of the second slit run towards one another from the first longitudinal section towards the profile wall opening.
  • the common head end of the first and second slot preferably lies in the plane of symmetry of the profile wall opening in the longitudinal direction of the hollow profile, in order to evenly adapt the current flow through the handrail to the line cross section that tapers in the area of the profile wall opening. This further increases the short-circuit resistance of the handrail, even at particularly high voltages.
  • the recess can have a third slit and a fourth slit, of which one slit follows the first or second slit at a distance, in order to further suppress even singularities in the current flow at the recess. This can further improve the stability of the handrail.
  • one slit can follow the first or second slit in parallel offset sections.
  • the first and second slots are preferably curved in the entire first longitudinal section, which further promotes the even flow of current.
  • the construction can be further simplified if the first slit is positively curved and the second slit is negatively curved.
  • the insert By relaxing the requirements for an insert due to the recess before and/or after the profile opening, it can also be possible for the insert to have a plastic material.
  • the housing of the insert can be made of plastic without having to worry about the insert melting or burning in the event of an evacuation.
  • a handrail 1 is partially shown, the insert 20 and a metallic hollow profile 3, namely a metal tube.
  • a profile wall opening 4 is provided in the hollow profile 3 and is introduced into the hollow profile 3 by a cutting process, for example.
  • the insert 20 is arranged in this profile wall opening 4, namely the housing 5 is countersunk in the hollow profile 3 used.
  • an illumination device 2 with LED 14 forms the insert 20, with other inserts 20 not shown being conceivable.
  • the LEDs 2a emit light through a window 5a in the plastic housing 5 to illuminate the handrail 1 and/or to illuminate the surroundings.
  • a recess 6 is provided at a front end 4a, 4b of the profile wall opening 4, viewed in the longitudinal direction L of the hollow profile 3.
  • the recess 6 has a first slot 7 and a second slot 8, the courses of which diverge in a first longitudinal section 6a of the recess 6 from a common head end 9 to the profile wall opening 4, as is shown in 3 can be recognized.
  • the one dashed in 3 drawn hotspot 10 are avoided, where the known inserts 20 despite high Insulation protection class can ignite. Fires on the handrail 1 are thus avoided according to the invention, which can ensure the functionality of the safe evacuation of people from a danger area, even when the handrail 1 is exposed to high voltage.
  • the first and second slot 7, 8 end at a longitudinal distance A from the profile wall opening 4, which leads to a web 11 between the recess 6 and the profile wall opening 4, in order to ensure the mechanical stability of the handrail 1.
  • the maximum opening width b is also shown transversely to the longitudinal direction L of the hollow profile 3 .
  • the courses of the first and second slots 7, 8 in the first longitudinal section 6a also diverge towards this maximum opening width b.
  • a second longitudinal section 6b of the recess 6 adjoins this first longitudinal section 6a.
  • the courses of the first and the second slot 7, 8 run towards one another from the first longitudinal section 6a to the profile wall opening 4.
  • the common head end 9 of the first and second slot 7, 8 lies in the plane of symmetry E of the profile wall opening 4 in the longitudinal direction L of the hollow profile 3.
  • the recess 6 is also mirror-symmetrical in the longitudinal direction L of the hollow profile 3. This can provide a smooth approximation to the cross-sectional taper in the electrical conductivity of the handrail 1 due to the profiled wall opening 4 .
  • the recess 6 has a third slot 12 and a fourth slot 13, of which the third slot 12 follows the first slot 7 and the fourth slot 13 follows the second slot 8 at a distance. This can even avoid singularities in the current flow at the first and second slots 7, 8.
  • the third and fourth slot 12, 13 also end in front of the profile wall opening 4, the transverse distance B between these slot ends 12a, 13a being greater than the maximum opening width b of the profile wall opening 4.
  • first and second slot 7, 8 are curved in the entire first longitudinal section 6a, the first slot 7 here being positively curved and the second slot 8 being negatively curved.
