Definitions

  • the invention relates to a fall protection device for the closure elements of building and vehicle closures, the closure elements being movable by rollers and the like in vertical or oblique guides.
  • the fall protection becomes jerky or jerky, which e.g. is always unavoidable if the fall protection is effected by bolts or pawls.
  • the invention is essentially based on the problem of proposing a fall protection of the above type which the above disadvantages are avoided and, in particular, that the movable parts of the closures certainly come to a standstill, but not suddenly, but in a gentle manner with a certain, but fixed braking distance.
  • the guide track for the rollers or the like can be narrowed by means of a jaw which can be moved transversely to this track.
  • a transverse movement of this jaw thus narrows the guideway in such a way that the rollers or the like jam in this narrowing, it being understood that the braking effect produced in this way is not sudden, but dependent from the gradually increasing narrowing.
  • These jaws which are thus comparable to the jaws customary in brakes, can be special, individually arranged elements, but it is particularly expedient to divide the guide rails in order to be able to use a rail section as a jaw, advantageously to achieve one Narrowing a pivotable mounting of this rail section is provided.
  • the jaw is preferably assigned a spring which can be locked in the tensioned state, in particular a compression spring, which is released from its locking for the purpose of the jaw movement.
  • the invention is based on the fact that the building or vehicle lock is driven via a rope or the like in connection with a loose roller on which a tension spring acts, which is constantly under tension, in this way that even short-term relief or delayed movements of individual sections do not lead to the preload being released. If, however, a rope break or a spring break occurs, the spring is also released and this spring sinks downwards. This lowering movement is now used to trigger the locking mentioned.
  • a tension element is attached to the lower end of the spring and is pulled down as the spring sinks. If a locking bolt is fastened to the upper end of the pulling element, this moves with the actuation of the pulling element to release the spring to act on the jaws mentioned.
  • the locking means for releasing a backward movement can at least be approximately returned to the original position under spring force and, moreover, the locking means in the retracted position, when the locking mechanism is triggered, prevents the jaws from being returned.
  • the locking means has a double function; on the one hand it locks the mentioned jaws or the plunger acting on them in the rest position, on the other hand this means blocks or secures the jaw when it is in the active position, that is to say it should hold the rollers of the closure elements.
  • This means expediently stands. under the action of springs; the associated spring then leads the agent back to its original position, but the jaw has now assumed the operative position or the clamping position. In this original position, the agent secures the jaw against folding back or the like, so that it can take on comparatively greater clamping and holding forces.
  • the locking means or the aforementioned bolt acts in a wedge-like manner at its front end on the cheek or the plunger acting on it. This results in large holding forces, which helps the jaw to achieve appropriate clamping forces.
  • interconnected sections 1 of the gate as a closure for a building opening have at their ends or joints cross bolts 2 for storing rollers 3. These are on both sides of the building opening vertical guide rails 4 assigned pass over a 90 ° bend 5 into a horizontal section 6 of the guideway. This section 6 serves to receive the sections 1 when the closure is in the rest position, while the guide rails 4 receive the sections 1 when the building opening is closed.
  • the building lock is driven by an electric motor (not shown in more detail) in connection with a pull rope 7, which is guided at its lower end via a loose roller 8.
  • This roller 8 is provided with a holder 9 for the upper end of a vertically arranged tension spring 10, which in turn is connected to a slightly lowerable lower holder 11 at the lower end.
  • the guide track for the rollers 3 with the sections 4, 5 and 6 have a substantially C-shaped cross-section which, however, au E h may be configured differently. While sections 4, 6 ′ have a rigid cross section, section 5 or bend 5 is divided. Both arc parts 12, 13 have one approximately J-shaped cross section with a slightly overlapping leg 14. While the lower arch part 13 is rigidly and immovably supported, the upper arch part 12 can be pivoted about a horizontal axis 15 located at its upper end, specifically from that shown in the drawing Normal position from in the direction of arrow 16. Accordingly, the two bow parts 12, 13 assume the position shown in FIG. 3 under normal operating conditions, accordingly the rollers 3 - just like in sections 4, 6 - can be moved freely.
  • a compression spring 21 which is assigned to the locking bolt 19 and which tries to hold the locking bolt 19 in the operative position according to the drawing, is also supported.
  • a rope 22 which is guided vertically downward, engages the holder 9 freely and is fastened to the lower, lowerable holder 11.
  • tension spring 10 is under prestress in the operating state and is therefore elongated to a certain extent. Accordingly, certain defined strokes can occur in the area of the loose roller 8 without releasing the pretension.
  • the rope 22 according to FIG. 3 is provided with a predetermined breaking point in the form of a wire eye 24 which is more easily destroyed.
  • sliding shoes can also be used, since clamping or prior braking is also possible with them.
  • the upper end 24 has an inclined surface 25 on the side facing the curved part 12, which corresponds to a correspondingly extending inclined surface 26 of the shoe 22.
  • the rise of these inclined surfaces 25, 26 is selected so that self-locking occurs, but that a longitudinal movement of the locking bolt 19 leads to a movement of the curved part 12 in the direction of arrow 16, that is to say an increase in the pressure in the clamping area.
  • the vertical bearing point 27 of the locking bolt 19 and the horizontal bearing point 28 are firmly anchored to a common bearing plate 20.
  • a fixed stop point 3o formed by the bearing plate 2o can optionally also be provided on the rear side 29 of the upper end 24 in order to switch backward evasive movements of the locking bolt 19.
