Definitions

  • the invention relates to a protective profile strip for an electrical contact tube arranged in the interior thereof according to the preamble of patent claim 1.
  • Electrical contact hoses have been known for some time. Inside, they have two diametrically opposite electrically conductive strips. By deformation of the contact tube, i.e. by squeezing it, the two strips touch each other, short-circuiting a circuit and triggering a signal.
  • the distance the two strips travel until they come into contact is naturally small. This does not matter as long as the contact hose is laid in floors, for example, where it is actuated by traffic moving over it (which can also include pedestrians). However, if the contact hose is used for other purposes, for example as a so-called pinch protection on a horizontally moving door, on which it is mounted on its vertical edge, this deformation path is no longer sufficient.
  • the contact tube is then packed into the inside of a profile strip, which has a much larger deformation path, but which in turn compresses the contact tube in the first phase of the deformation, so that the requested signal is triggered immediately and thus the risk of damage or injury to the pinched object ( body parts such as arms or hands can also be avoided).
  • a further tape leads to the corresponding upper corner of the printing part, the side of each tape facing towards the printing part being curved, the outer side being straight, so that the tapes are thinnest at half their height and should actually be easy to deform in order to guide the above-mentioned pressure rib straight down as far as possible to the contact tube.
  • the invention therefore aims to avoid the deformations mentioned and to create a protective profile strip which is deflected laterally or obliquely by a suitable arrangement and shape of the individual parts in such a way that they lead to the greatest possible vertical displacement of the pressure ribs actuating the contact tube, with at the same time minimal deformation resistance of the strip when these forces act.
  • Such a protective profile strip of the type mentioned is characterized by the characterizing features of claim 1.
  • the protective profile strip is divided into three zones, namely a deformation zone 1, a contact tripping zone 2 arranged below it and a third zone attached under this zone 2, the foot zone 3. These zones will now be explained in more detail in order.
  • the deformation zone 1 is intended to absorb compressive forces and to transmit them to the contact tube 4. These compressive forces can result, for example, from contact with any object acting on this zone that actually or only moves relative to the deformation zone. Body parts of the human being, such as arms, hands or even fingers, which may not be injured when being pinched, can also be considered as an object. This determines the permissible deformation path; The so-called overtravel after the contact has been triggered must also be taken into account. Depending on these requirements, the deformation zone 1 is therefore higher or lower.
  • the deformation path must in any case be large enough to be able to absorb both forces which act parallel to the longitudinal central axis AA of the profile strip and those up to an angle of at least 45 ° to this axis.
  • the deformation zone 1 has a sealing region 11 and two mutually parallel walls 12. Both the shape of the sealing area, the top section of which seals against a corresponding object (door frame, wall, equivalent sealing area of another, opposing protective profile strip), as well as the length of the walls 12 are based on the previously mentioned requirements. In order to achieve the certain resistance or stiffness against deformation which is also mentioned, a number of transverse webs 13 are provided between the walls 12 at certain distances from one another. With a suitable choice of the thickness of the walls 12 and the transverse webs 13, a box-shaped structure is obtained which meets these requirements.
  • the contact release zone 2 contains the contact hose 4 already mentioned. This is known per se, which is why it should only be mentioned here that its upper part 41 and its lower part 42 each have an electrically conductive surface on their mutually opposite inner sides, which touch when the contact hose is pressed together and like that trigger an electrical signal.
  • the contact tube 4 is located within a cavity 21, which of course must be deformable itself.
  • the walls 23 are designed in such a way that their inner side 26 facing the cavity runs obliquely, ie not parallel to the other side, so that the wall at the transition to the base 22 is thicker than at its upper end, which forms a connection point 27. As a result, the walls 23 become very stiff against deflection. This stiffness is reinforced by the fact that the centering belts 24 are not arranged horizontally but at an angle, which reduces the height of the walls 23.
  • each connection point 27 acts like a joint about which the centering band 24 in question can swing like a lever arm.
  • This enables the pressure part 25, under an axial pressure or such a pressure component, to approach the base 22, thereby compressing the contact tube 4 and thus bringing about the triggering of the contact, without having to carry out such a large transverse displacement because of the horizontal yielding of the walls 23 that a compression of the contact tube 4 is no longer possible.
  • two ribs 28 projecting into the cavity 21 are attached in the head 250 of the pressure part 25. These are arranged as far as possible from one another so that even when the pressure part 25 is at a steep incline, one of these ribs 28 still presses on the contact tube 4.
  • the ribs are attached so that their tips 280 are exactly each are located vertically under the point at which the corresponding outer side 251 of the pressure part 25 meets the upper side of the corresponding tension band 24.
  • the pressure part 25 in the exemplary embodiment shown consists of a horizontal one Side of a triangle-forming base plate 252 and two struts 253 forming the other sides of this triangle, which run obliquely towards the head 250 connecting them, but do not unite.
  • the base plate 252 simultaneously forms the end of the deformation zone 1. They and the struts 253 close one Cavity 254, which is only due to manufacturing technology.
  • the pressure part 25 could also be designed as a full body.
  • the pressure part 25 is surrounded on its outside by two curved, film-like connecting pieces, which are to be referred to as tension bands for reasons to be explained; they are designated 29 in the figure.
  • tension bands for reasons to be explained; they are designated 29 in the figure.
  • they are considerably thinner than, for example, the walls of the deformation zone 1 or the pressure part 25. They extend from the outer ends of the base plate 252 to the connection points 27 mentioned above between the tension bands 24 and the walls 23 Course on their outer and inner sides, which is most appropriately executed against the pressure part 25, ensures, even with their consequent constant but small thickness, a bending which practically offers no resistance to the corresponding displacement of the pressure part 25 downward under a purely axial pressure effect , so that contact is triggered even with low pressure forces.
  • the head 250 with the ribs 28 is now much lower than this new axis of rotation C, it can only pivot about this with a strong downward movement. At least the right rib 28 reaches the contact tube 4 and presses it together, so that the required contact is triggered.
  • tapes 29 are referred to as drawstrings.
  • the aforementioned stretching of the one band 29 puts it under tension and makes it practically a lever arm, which leads to the position definition of the mentioned pivot axis C.
  • both the centering bands 24 and the curvature of the tensioning bands 29 are of significant importance. If the former were not present and the drawstrings 29 were rectilinear, there would be no pivoting movement as described above, but the base 252 of the printing part would shift strongly to the right, in the manner of a parallelogram shift. In such a case, the parallelogram would be formed by the base plate 252, the two exactly vertical tension bands 29 and the base 22, and the pivoting of the tension bands would take place around the connection point 27. However, this would result in such a strong lateral displacement of the head 250 that it is no longer certain whether one of the ribs 28 comes into contact with the contact tube 4 at all.
