Definitions

  • the invention relates to a barrier boom for a barrier system, in particular for controlling the passage of vehicles, according to the preamble of claim 1.
  • Such a barrier boom is essentially formed by a boom profile made of a metallic material, such as an extruded aluminum profile, or a plastic or plastic composite material, and is normally a hollow profile with grooves, rails and undercuts for attachments as required.
  • the boom profile with covers, foils, paintwork or the like and, depending on the application, a hinge, forms the essential part of the barrier boom.
  • a light-emitting strip in particular an LED strip, is attached to the underside of a barrier boom of the present type over at least part of the length of the boom profile in order to emit visible light into the area surrounding the barrier boom.
  • the light-emitting strip can emit light over its entire length or at several points distributed over its length, with the light sources distributed over its length preferably being arranged equidistantly.
  • Barrier booms illuminated by one or more light-emitting strips have been known for some time, particularly in barrier systems for controlling the passage of vehicles, as is common in managed parking lots, multi-storey car parks, toll booths or areas accessible only to authorised users.
  • the lighting is not only used at night and during poor lighting conditions to make the closed barrier easier to recognize, but can also send out optical signals through color changes, flashing signals and the like and thus provide information to the environment, in particular vehicle drivers, operating personnel and/or security personnel.
  • the problem here is that the light emitted by the light-emitting strip can cause glare, as is often the case when the light-emitting strip is attached to the side surfaces of the tree profile so that drivers look directly at the light source.
  • An example of a tree profile with light emitted from the side is disclosed in KR 20130012677 A. Such an example can also be found in WO 2017/201212 A1.
  • CN 205742012 U proposed attaching the light-emitting strip to the top of the boom profile so that its light can also be seen at the front and back of the barrier system.
  • CN 205742012 U proposed attaching the light-emitting strip to the top of the boom profile so that its light can also be seen at the front and back of the barrier system.
  • barrier booms were therefore proposed in which a light-emitting strip is attached to the underside of the boom profile.
  • An edge protection arranged underneath for example made of silicone, is translucent and serves as a diffuser for the light emitted by the strip, so that it can be perceived on both sides of the barrier boom.
  • add-on parts such as a barrier grille or pendulum supports
  • the present invention is therefore based on the object of improving a barrier boom of the type mentioned at the outset, which is equipped with a light-emitting strip on the underside of its boom profile, with regard to the possibility of attaching add-on parts to the boom profile.
  • a barrier boom of the present type with a boom profile which forms the essential part of the barrier boom and is equipped with a light-emitting strip on its underside which extends over at least part of the length of the boom profile and emits light over its entire length or at several points distributed over its length, is thus further developed according to the invention in such a way that the light-emitting strip is combined with a light guide into which it radiates the light, that the light guide is attached to the boom profile below it, and that a support rail for attachments is provided below the light guide, which is attached to the light guide and/or the boom profile.
  • the light guide used according to the invention which can guide the light from the light-emitting strip to an outside of the tree profile, makes it possible to attach a support rail underneath the light-emitting strip, which does not have to be transparent and can therefore consist in particular of a metallic material.
  • the light guide can guide the light from the light-emitting strip outwards, in particular between the tree profile and the support rail, so that it is visible from the outside on the side surface of the tree profile, even if the support rail covers the light guide at the bottom.
  • the support rail makes it possible to attach a wide variety of attachments to the barrier boom, in particular a barrier grille or pendulum supports, or even a soft-elastic edge protection, which are regularly attached to the underside of the boom profile.
  • the boom profile of a barrier boom of this type is often provided with at least one mounting groove on the underside in order to be able to attach the aforementioned attachments.
  • the light-emitting strip is located in such a mounting groove on the underside of the boom profile.
  • the strip is simply pushed into the mounting groove during installation.
  • the light guide provided according to the invention into which the light-emitting strip couples the light, is preferably also inserted in a form-fitting manner into the tree profile or attached to it, for example by engaging behind undercuts in the profile or undercut grooves of corresponding rail-shaped recesses in the light guide.
  • a correspondingly shaped light guide is also inserted lengthwise into the tree profile.
  • the carrier rail is also positively seated on the light guide and/or on the boom profile. It is particularly preferred if the light guide has a profile with undercuts and the carrier rail is positively inserted into these undercuts of the light guide, in particular simply pushed in.
  • the support rail can be inserted or pushed either in a form-fitting manner onto the light guide or in a form-fitting manner into the boom profile. In this way, a barrier boom with lighting and a barrier boom without lighting can be assembled from identical parts.
  • the carrier rail has a mounting groove on the underside that is essentially identical to the tree profile (if the tree profile is provided with such a groove).
  • the barrier boom is provided with lighting, i.e. according to the invention with a light-emitting strip, a light guide and the support rail, or not.
  • the support rail is provided with essentially the same profile as the underside of the boom profile, the underside of the barrier boom is completely unchanged, regardless of whether it is equipped with lighting or not.
  • this development of the present invention therefore provides an option for attaching a light-emitting strip to the underside of the barrier boom, which ultimately leaves the externally accessible profile of the underside of the barrier boom unchanged.
  • the support rail covers the light guide downwards, in such a way that the light guide forms a light exit surface that is visible from the outside only on the side of the barrier boom, preferably on both sides of the barrier boom.
  • the light guide forms a light exit surface that is visible from the outside only on the side of the barrier boom, preferably on both sides of the barrier boom.
  • the present invention it is therefore possible to achieve lighting of the barrier boom for the purpose of better recognition and/or signaling, which can be seen on both sides of the barrier boom, from the front and from the back of the barrier system, without having to provide two light-emitting strips, without attaching the light signaling to the top of the barrier boom, where it can be misinterpreted when the barriers are open and there are several adjacent barrier systems, and without having to accept a glare effect on the underside of the barrier boom or without having to do without add-on parts such as a barrier grille or pendulum supports.
  • the light exit surface or both light exit surfaces of the light guide are each provided with a matt surface for light scattering, which is known to significantly improve visibility from different viewing angles.
  • the light exit surfaces can also be provided with prism-shaped recesses running along the tree profile.
  • the light signaling or lighting is to be visible on both sides of the barrier boom, it is preferred within the scope of the present invention to attach the light-emitting strip approximately centrally to the underside of the boom profile and to provide a prism-shaped interface in the light guide, below the light-emitting strip, for redirecting the light to both sides of the barrier boom.
  • the light guide can be essentially V-shaped in its profile in order to direct the light upwards using the V-shaped legs, so that the light exit surfaces are arranged at the same height as or even above the light-emitting strip.
  • the light exit surfaces will then still be arranged in the lower area of the barrier boom sides, but there will be no light exit to the underside of the barrier boom, so that any glare or misinterpretation is excluded here; the light signaling can then only be seen when approaching the barrier boom from the front or the back.
  • Figure 1 is a schematic view of a barrier system with a barrier boom designed according to the invention
  • Figure 2 shows the profile of a barrier boom from Figure 1, but in a design according to the prior art
  • Figure 3 shows the profile of a barrier boom designed according to the invention
  • Figure 4 shows a partial section from Figure 3
  • FIG. 5 shows detail A from Figure 3.
  • the barrier system for controlling the passage of vehicles shown in a schematic view in Figure 1 comprises a barrier boom 1 with a boom profile 2 which, provided with foils 3 and reflectors 4, forms the essential part of the barrier boom 1, as well as a barrier housing 5 on which the barrier boom 1 is pivotally mounted and which contains the drive (not visible) for the barrier boom 1.
  • the barrier boom 1 shown in Figure 1 is equipped with a light signaling system according to the invention, which is why a support rail 6 is arranged on the underside of the barrier boom 1. Between the support rail 6 and the boom profile 2, arranged on the side of the barrier boom 1 in its lower area, a light exit surface 7 of a light guide 8 (otherwise not visible here) can be seen. This light signaling can also be found on the back of the barrier boom 1 (not visible here).
  • the light signaling is very clearly visible on both sides of the barrier boom 1, i.e. when approaching it from the front and from the back, but not from above and from below, which becomes important when the barrier boom 1 is in its open position
  • the narrow light-emitting surface 7 on the barrier boom 1 is clearly positioned in its lower area, which is visible at first glance and is perceived as such, even when the barrier boom 1 is in its open position; the risk of confusion when there are several barrier systems arranged next to one another is thus minimized.
  • the light exit surface 7 can only serve to illuminate the barrier boom 1 in poor lighting conditions and in particular at night in order to make it visible. However, it can preferably also be used for signaling purposes, for example by a red light indicating that passage is not possible and a green light signaling that entry is possible with appropriate authorization and the like, for example also by using flashing signals and/or running lights.
  • FIG 2 shows a section through a barrier boom 1, such as can be used in the prior art in a barrier system from Figure 1.
  • This barrier boom 1 is designed according to the prior art.
  • the boom profile 2 of this barrier boom 1 consists of an aluminum extruded profile, which is equipped on its underside with profile rails 9, with undercuts 10 created by these and with a mounting groove 11.
  • a soft elastic edge protection 12 is inserted into the mounting groove 11, which sits in a form-fitting manner in the boom profile 2 due to the undercuts 10.
  • FIG 3 shows, in a representation corresponding to Figure 2, the inventive development of the barrier boom 1 from Figure 2:
  • the boom profile 2 itself is designed identically to the example from the prior art shown in Figure 2, ie the mounting groove 11, the profile rails 9 and the undercuts 10 are still present on its underside.
  • a light-emitting strip 13 is now inserted into the mounting groove 11 in a form-fitting manner, which emits light downwards from the mounting groove 11 and couples it into the light guide 8.
  • the light guide 8 is approximately V-shaped in its profile and consists of a profiled molded part with first rail elements 14, which engage behind the undercuts 10 of the profile rails 9 of the tree profile 2 and thus enable the light guide 8 to be inserted lengthwise into the profile rails 9 of the tree profile 2 for a positive connection.
  • the light guide 8 On its underside, the light guide 8 is provided with second rail elements 15, which in turn form undercuts in order to form-fit hook-shaped bends 16 of the support rail 6 in the profile.
  • the support rail 6 can therefore also be inserted lengthwise in a form-fit manner into the second rail elements 15 of the light guide 8, so that a stable connection is created between the tree profile 2, the light guide 8 and the support rail 6, without having to provide additional mounting means.
  • the support rail 6 also consists of an extruded aluminum profile, and its profiling is designed such that it corresponds to the profiling of the underside of the boom profile 2, in particular with a support rail mounting groove 17.
  • the edge protection 12 which is designed identically to the prior art according to Figure 2, is inserted into this support rail mounting groove 17 in the same form-fitting manner as in the boom profile 2 according to the prior art ( Figure 2), i.e. from the point of view of the edge protection 12, nothing has changed as a result of the inventive design with light-emitting strip 13, light guide 8 and support rail 6.
  • FIG 4 which shows the lower section of the tree profile 2 from Figure 3, light, which is symbolized by a light beam 18, is emitted downwards from the light-emitting strip 13 and coupled into the light guide 8, where a prism-shaped boundary surface 19 deflects the light beam 18 to the side.
  • the light beam 18 is then guided within the light guide 8 to the light exit surface 7, where it exits into the open, preferably in a horizontal orientation.
  • the support rail 6 covers the light guide 8 downwards, so that the light of the light-emitting strip 13 is actually only perceptible at the light exit surfaces 7.
  • Figure 5 shows detail A from Figure 3 in an enlargement to illustrate that the light exit surface 7 is provided with a series of prism-shaped recesses 20 running along the tree profile 2 in order to scatter the light beam 18 on the light exit surface 7 and thereby improve the perceptibility of the light signaling.
