  • the post distance is often 2.4 m and the length of the side guards between about 2.6 m and 2.7 m, so that a certain length of the side guards in an overlap area always remains unused.
  • weights of the side guards in the range from 24 kg to 32 kg result. In this respect, it is disadvantageous that the attachment and dismantling of the side guards requires at least two people due to this weight.
  • the invention has the object, advantageously further develop a side guard of the type mentioned, so that in particular the aforementioned disadvantages can be avoided as much as possible.
  • the object is to provide a side guard, which can be handled by only one person due to its reduced weight and meets the requirements of the current regulations.

  • the outer frame may be lighter in weight compared to conventional side guards, and one skilled in the art will understand that other aluminum alloys could equally be used instead of aluminum alloy.
  • an aluminum side guard with a length of 3 m and a height of 1.25 m, in which the frame profile has dimensions of 48 mm ⁇ 35 mm in cross section, can be provided with a dead weight of only about 16 kg .
  • the frame segments may have a comparatively larger frame cross-section compared to known steel side guards and a smaller wall thickness as a hollow profile.
  • the frame cross-section results in a higher frame stability and, as will be explained below, railing posts can be dispensed with.
  • the invention provides that the wire mesh is not time-consuming and thus costly welded to the frame as in the prior art. Instead the invention provides that the wire mesh at its edges positively into the undercut of the longitudinal grooves, which are insofar also to be referred to as retaining grooves engages. In particular, when the grid is held positively in all four wheels or sides, so along its edge circumferentially in the undercut longitudinal grooves, a particularly strong and secure connection between the wire mesh and outer frame is guaranteed.
  • the wire mesh can have longitudinal and transverse rods, for example, of steel (in particular of galvanized steel) or of other materials (conceivable here as well would be light metal, such as aluminum alloy.)
  • the edge-fitting engagement makes it possible to use wire meshes with comparatively low wire thickness
  • Another advantage is seen in the fact that the outer frame of the side protection grid according to the invention, for example, for repair, disassembled and, for example, the wire mesh can be removed and replaced preferred mounting can be carried out so that the frame segments pushed with their undercut longitudinal groove on the edge longitudinal or transverse bars of the wire grid in their respective longitudinal direction and the frame segments are then bolted together at their corner-side contact zones - Making use of the light, an undercut longitudinal groove having frame segments to use the weight advantage of light metal or aluminum alloy and still ensure a simple, detachable and secure connection between the frame and the wire mesh or wire mesh.

  • rail posts can therefore be dispensed with and thus a further simplification can be achieved in comparison with a side protection system known from the prior art which has railing posts.
  • a preferred development of fiction, contemporary side guards is seen in that the frame segments are designed as a profile tube and that said longitudinal groove is bounded by a wall extending from the outer wall of the profile tube U-profile-like in the interior.
  • a profile tube offers over a solid profile the advantage that can be achieved with comparatively low weight large cross-sectional dimensions and thus high rigidity.
  • the frame segments or profile tubes are aligned during assembly of the side guard so that the respective longitudinal groove to the frame interior, ie facing the wire mesh.
  • the groove orifice in the outer wall of the profiled tube adjoins one side of a center plane of the profiled tube perpendicular to the reference cross section and the rear section extends to the other side of the median plane with respect to the groove mouth ,
  • a profile tube can optionally be integrated into the frame in two different rotational positions, each with a longitudinal groove pointing toward the wire mesh, wherein the undercut, depending on the rotational position, can be on different sides of the center plane of the frame.

  • the longitudinal bars are located in a common bar level and that the transverse bars are located in a common second bar level. It can thereby be achieved geometrically that the plane of extent of the longitudinal bars corresponds to the plane of extension of the longitudinal grooves in the horizontally extending frame segments, for example, and the plane of extent of the transverse bars corresponds to the plane of extent of the longitudinal grooves in the frame segments perpendicular thereto.
  • the profile tube has two mutually parallel spaced opposite planar wall portions, which are circumferentially connected by two in cross-section at least substantially arcuate wall portions, and that the longitudinal groove, starting from one of the two arcuate wall portions toward the profile inside is formed pointing.

  • a safety hook can be used if two side guards are to be arranged overlapping each other to achieve a very specific desired side protection length. For this purpose, a side guard can be plugged into a holding area of a ground support and the second side guard on the first side guard with overlapping arrangement are held laterally with the safety hook.

Abstract

L'invention concerne une grille de protection latérale qui comprend au moins une grille métallique (2), présentant des barres longitudinales (3) et des barres transversales (4), et un cadre extérieur (7) délimitant la grille métallique (2). Le but de l'invention est de perfectionner avantageusement une grille de protection latérale du type mentionné ci-dessus. A cet effet, le cadre extérieur (7) présente au moins quatre segments de cadre (8, 9), chaque segment (8, 9) s'étendant le long d'un côté de bordure de la grille métallique (2), deux segments de cadre (8, 9) étant reliés les uns aux autres de façon amovible, en particulier vissés, sur les angles de la grille métallique (2); les segments de cadre (8, 9) sont fabriqués en alliage d'aluminium; une rainure longitudinale (11) présentant au moins une contre-dépouille (12) est réalisée sur les segments de cadre (8, 9), et les barres longitudinales (3) côté bordure et les barres transversales (4) côté bordure de la grille métallique (2) s'engagent dans la contre-dépouille (12) de la rainure longitudinale (11) sur le segment de cadre (8, 9) qui leur est associé en fonction de leur position.
