Definitions

  • the invention relates to a swing gate protection for swing gates with tension spring.
  • the up-and-over door safety device is designed as a down-door protection and prevents the up-and-over door from falling after a spring holding the up-and-over door breaks.
  • the up-and-over door is connected to the spring via a tension cable, which transfers the spring force to the up-and-over door.
  • a securing device is arranged in the area of the tensioning cable, which is essentially formed from a spring-loaded plunger and a spring-loaded catch pawl. The tappet and the catch pawl are pulled in opposite directions by the tension of the rope.
  • the device ensures that the overhead door does not fall, but after the tension spring breaks, considerable damage can be caused by spring parts moving in an uncontrolled manner.
  • a protective element for coil springs which prevents an uncontrolled movement of the coil spring parts after a spring break.
  • This protective element is loop-shaped and extends through the coil spring.
  • the coil spring parts can change their position only insignificantly due to the extension of the protective element through the interior of the coil spring parts, so that damage to the surroundings of the coil spring is largely excluded.
  • a crash of a swing gate provided with the coil spring cannot be avoided.
  • a protective element for coil springs is also known, which prevents an uncontrolled movement of the coil spring parts after a spring break.
  • This protective element is designed as a variable-length protective sheath of the coil spring by two or more displaceable sleeves. Due to their end formations, the sleeves block the longest possible extension position against each other. With the help of this device, however, a crash of a swing gate provided with the helical spring cannot be avoided either.
  • the object of the present invention is therefore to construct a swing gate safety device of the type mentioned in the introduction in such a way that it has a simple structure and at the same time reliably prevents both a falling of the swing gate and a deflection of spring parts.
  • the tubular parts which are guided into one another prevent the spring parts from deflecting because of their rod action and their fixed door connections.
  • the up-and-over door lock Due to the design of the up-and-over door lock according to the invention, this can be mounted as a simple, inexpensive additional and retrofit part in the spring cores of the door tension spring and can be connected to the upper door lever arms and lower spring holders of the various door brands by closing parts, which are designed, for example, as tabs, links or washers .
  • an adjusting ring is provided in the area of the inner tube part, which limits the spring retraction when the door leaf opens and cancels the spring drive force in the running rails. This adjusting ring ensures that the spring travel, which is variable by setting the driving force, is equal to the constant lever travel of the door leaf in favor of a soft stop in the running rails.
  • a sleeve is arranged as a closure on the inner tube part and lies against the outer tube part. This achieves an air pump effect and, depending on the use of single or double cuffs and air metering by means of a metering screw, the opening and closing speed of the door leaf is regulated. The resulting damping of the closing speed by reducing the vacuum results in a low-noise door leaf stop on a floor rail.
  • the figures show, on the one hand, the installation position of the device according to the invention and, on the other hand, also taking into account the connections (n, p), the position during the opening state of the door.
  • the compression spring (g) presses the eyelet receptacles (c, d) via the wedge rod (e) against the tension spring force acting as the gate clamping force when the gate is force-connected. If the tension spring force falls below the compressive force at the lower eyelet holder (d), the self-locking wedge surface of the wedge rod (e) moves by a certain stroke and generates a friction lock on the pipe displaceability via the ball (f), for example if the spring breaks.
  • Unlocking is carried out by external force and opening movements of the door while pushing the outer tube (a) and inner tube (b) together.
  • the interlocking pipe parts (a, b) prevent failure of the spring force, for example in the event of spring breakage, tear-off of the eyelets or bending of the eyelets due to their rod effect and their fixed door connections, the deflection of spring parts.
  • the starting force of the door tension spring (t) which acts as the driving force, is increased as required by extending the spring tension as a result of re-tensioning in order to achieve a balance with the load from the door mass and frictional forces. This increases the spring travel compared to a constant door lever travel with the consequence of an undesirable additional thrust when a door leaf stops in the running rails.
  • the adjusting ring (h) on the inner tube (b) limits the spring retraction or the spring travel and thus the additional force at the dead center in favor of a soft door leaf stop in the running rails when the door opens.
  • the soft fitting in the running tracks is therefore due to the equal positioning of the spring and lever travel.
  • the joint center piece (c) has an external pipe connection to the door lever with a venting and ventilation threaded hole with an air metering screw (m), which, via the additional single or double sleeve insert (i), serves as an internal seal in the inner tube (b) for the insertion and removal of the Controls pipe parts (a, b) depending on the speed. This achieves speed damping, especially when the door closes, and low-noise fogging on the bottom rail.
