Definitions

  • the invention relates to an elastic profile strip according to the preamble of claim 1.
  • the aim of the invention is to provide an elastic profile strip of the type mentioned, which is particularly simple in construction with a simple possibility of manufacture and nevertheless with all occurring stresses, i.e. both in the case of centrally and laterally acting forces, the contact strip is made safe and quickly.
  • the cavity which is present in the elastic profile and which is essentially triangular in cross section is largely fully utilized for accommodating the intermediate profile, which in turn contains the electrical safety edge.
  • the changes in curvature of the side surfaces that occur when the elastic profile is deformed are passed on to one of the legs of the intermediate profile, which is then deformed so that the associated actuation projection presses essentially from above onto the switching strip and deforms it so that contact is reliably made.
  • a response is largely independent of the direction from which the profile strip is loaded.
  • a preferred embodiment is characterized in that the actuating ribs are at a short distance from the switching strip. In this way it is ensured that not every slight touch of the hollow profile leads to making contact, but that certain paths have to be covered before the contact strips in the switching strip touch.
  • a preferred embodiment is characterized in that, in the normal state, at most the outer ends of the legs of the intermediate profile touch the side surfaces of the profile, preferably leaving a slight distance, in particular up to about 2 mm.
  • the design should be such that the base piece is laterally spaced from the legs.
  • the outer ends of the webs center the intermediate profile lying against the base with the base piece.
  • the insertion of the intermediate profile into the cavity is possible with little effort, because the legs, which are clearly spaced apart, give way slightly inwards by springs and can thus be drawn into the elastic profile with only slight frictional resistance.
  • the intermediate profile nevertheless assumes a defined position within the elastic profile, because the webs rebound and thus take over the securing of the position of the intermediate profile in the cavity of the elastic outer profile.
  • the above-described function is not impaired if the intermediate profile can be displaced to a small extent from the central position on both sides, which is possible if the outer ends of the legs of the intermediate profile are at a short distance of up to 2 mm from the side faces.
  • the legs in the area of the switching strip are at a clear angle of preferably 30 to 60 °, in particular approximately 40 to 50 °, from the base Extend piece to above the safety edge and bend there, forming the actuating ribs, in a direction essentially perpendicular to the base piece and preferably bend it.
  • legs have a concave curved outer surface, preferably similar to the curvature of the side surfaces in the undeformed state.
  • the intermediate profile serves at the same time to carry the profile strip, which is preferably glued to the base piece, to form the actuating ribs for the switching strip and to form the actuating end pieces of the legs.
  • An advantageous development of the invention is characterized in that friction and abrasion-reducing foils are arranged between the legs and the switching strip.
  • the films should be glued to the legs.
  • a further embodiment is designed such that axial, preferably inwardly open channels are provided in the transition area from the base piece to the legs, in which reinforcing wires are arranged.
  • an elastic profile 14 made of rubber for example, has an essentially triangular cross section, but the side faces 17 of the profile 14 according to FIG. 2 are slightly curved inwards, so that when the profile is bent in the direction of one of the arrows f in FIG. 2, the respectively assigned side surface 17 is more strongly arched and the opposite side surface 17 is stretched somewhat more. Due to the special triangular design of the profile 14, a bend in the direction of one of the arrows f also takes place when the profile 14 is stressed in the direction of arrow F from the opening to be closed. The bead-like triangular tip 19 of the elastic profile 14 facing the opening to be closed is then laterally deflected either in the direction of one or the other arrow f.
  • the elastic profile 14 has a base 26, which in a suitable manner, e.g. can be fastened by means of the grooves 27 to the closing edge, for example a door or a rolling gate.
  • an elastic intermediate profile 12 designed according to the invention is drawn, which can also be made of rubber.
  • the elastic intermediate profile 12 has an elongated and essentially flat base piece 15, which lies flat against the base 13 of the cavity 11.
  • the flat base piece 15 has an elongated depression 28, which has the purpose of making the intermediate profile 12 as flexible as possible.
  • the two outer surfaces of the legs 16 of the intermediate profile 12 could also have a circular concave curvature, as is indicated by the dash-dotted line 31 'in FIG. 3.
  • an electrical switching strip 18 is arranged in the middle, which consists of an elastic hollow profile 32, which has a flat base side and a semi-cylindrical actuating side, from which a switching rib 33 extends to the flat base area, on which an elastic pair of contact strips 34 is attached, which consists of two resilient metal strips held at a distance by an insulating material.
  • the electrical safety edge 18 is of the same design as that described in the published documents 32 32 365 and 33 12 223.
  • actuating ribs 20 are formed at a short distance from the electrical switching strip 18 and are located substantially slightly above the electrical switching strip 18.
  • the outer ends 21 of the legs 16 lie against the inside of the side surfaces 17 of the elastic profile 14.
  • an abrasion and friction-resistant polyester film 22 is inserted between the legs 16 and the electrical switching strip 18, which is preferably glued to the legs 16.
  • the film also serves for the chemical separation between the hollow profile 32 made of PVC and the intermediate profile 12 made of rubber.
  • axial reinforcing wires 25 In the transition area between the base piece 15 and the legs 16, approximately three-quarter circular axial longitudinal channels 24 are provided on the inside in the intermediate profile 12, in which, according to FIG. 2, axial reinforcing wires 25 can be arranged. From the base piece 15, around the lower longitudinal regions of the switching strip 18, there extend clamping tongues 35 which hold the switching strip 18 securely, which should additionally be glued in.
  • the intermediate profile 12 is shaped such that it only touches the inner walls of the cavity 11 with the lower surface of the base piece 15 and the ends 21 of the legs 16.
  • the cavity 11 is then closed at one end by a plug 36, while the electrical connection 37 is inserted from the other end, a closure piece 38 likewise being provided in this area.
  • the edge 19 in any case deviates in the direction of one of the arrows f, ie laterally, whereupon the associated side surface 17 of the elastic profile 14 assumes a greater curvature and the associated leg 16 presses inwards by reducing the distance A.
  • the actuating ribs 20 pivot essentially around the connection point with the base piece 15 and press in Fig. 2, 3 essentially from above onto the switching strip 18, whereupon the actuating rib 33 acts on the contact band pair 34 and brings about an electrical contact. A switching signal is thus triggered in a simple and safe manner.
  • the safety edge 18 there is therefore an intermediate profile 12 which can be inserted into the profile 14 and which, owing to the delta-shaped cross section, transmits an easy and reliable switching operation to the safety edge 18. Since the delta-shaped outer contour of the profile 14 has to buckle with every load, the lateral curvature of this profile 14 is always transferred to the intermediate profile 12. The transmission of the forces from the intermediate profile 12 to the switching strip 18 takes place via a lever arm. This produces a switching process with very little force.
  • the intermediate profile 12 is designed so that the elongated legs 16 absorb the bulge of the profile 14 and thus act on the safety edge 18 essentially from above.
