Definitions

  • the present invention relates to a bottom bracket for fall arresting a garage door, where the bottom bracket is fixed to a leaf of the garage door and arranged to be connected to a suspension wire from the spring suspension of the garage door, comprising an L-shaped corner plate, fastened adjacent to a side edge of said door leaf, with a bolt and a pulley wheel, fastened to the one side edge of the corner plate, arranged to roll in an adjoining side rail of the garage door, and where the corner plate comprises, on its other side edge, a rotatable fall arrest unit with a locking edge, which, under the influence of a spring force, is set up to engage with the side rail to stop or to brake the garage door if the suspension wire breaks or becomes loose.
  • the invention also relates to a side rail for use with a bottom bracket as described.
  • the invention relates to a bottom bracket on a garage door that is arranged to safeguard the door from falling down if there is a break in one single component in the suspension or the balancing system for the door.
  • the mechanism shall satisfy the new safety requirements that are to come into force. These safety requirements are specified in NS-EN 12604, and are a standard that shall be valid as a requirement from 2005.
  • DK B 162787 ( ⁇ ) 162787, amongst others, shall be mentioned.
  • This document concerns a catching mechanism for a garage door that is connected to a drive device, and where the catching mechanism comprises a housing with a spring loaded locking arm with a locking edge that is swung out if the suspension wire breaks. The locking edge is swung out and engages with catching openings in a catching rail fitted internally of the catching mechanism and the side rails, i.e. the catching rail is fitted to the garage wall.
  • EP 1199432 A1 relates to a braking mechanism for a garage door, where the braking mechanism is fitted to a side in the door opening and where the braking mechanism works with a locking element fastened to the garage door inside the pulley wheel that runs in the side rail. The locking element is swung out if the suspension wire breaks and engages with the braking mechanism fastened to the wall.
  • SE B 463628 shall also be mentioned, where a safety appliance for a garage door with moving doorplates is mentioned.
  • the object of the invention is to provide a device for fall arresting that is simple to produce, easy to fit and which further fall arrests garage doors with respect to present and new standards.
  • a bottom bracket is provided as described in the independent claim 1 , in that the fall arrest unit is rotatable fitted to a suspension bolt fastened to the side edge of the corner plate against the side rail, as the locking edge is placed across and directed downwards at a distance, adjoining and against the wall fastening side of the side rail, that said suspension wire is eccentrically connected to the fall arrest unit in relation to its mounting point, and contributes to maintain the locking edge at a given distance from the wall fastening side of the side rail when the suspension wire is taut and that the bottom bracket comprises spring means arranged to rotate the fall arrest unit so that the locking edge engages with an outwardly extending protrusion on the wall fastening side of the side rail if the suspension wire breaks or becomes loose.
  • the suspension bolt can be shaped as a bolt or a spike and the fall arrest unit can comprise one or more openings or recesses arranged for a rotatable fastening of the fall arrest unit to the suspension bolt.
  • the fall arrest unit preferably comprises at least one holding arm arranged to be supplied a force from said spring means.
  • the fall arrest unit can be formed as at least one partial sleeve part and incorporates holding arms lying on the outside on each side, where at least the one holding arm constitutes a wire safeguarding arm and comprises fastening means for connection to the suspension wire and also that the locking edge is arranged diagonally and directed downwards centrally in the fall arrest unit.
  • the fall arrest unit can be formed in a partial U-shape, where an inner part comprises, on its lower part, the locking edge, where the locking edge is arranged diagonally and directed downward centrally in the fall arrest unit, and that the side edges are made up of the holding arm and the fastening means for fastening of the suspension wire.
  • the corner plate can comprise a holding edge which at least one of the holding arms is arranged to lie against, when the fall arrest unit is in a passive position due to the pull in the wire of the suspension wire, and that said spring means comprises a spring which is arranged to rotate the fall arrest unit so that the locking edge engages with the protrusion on the side rail if the suspension wire breaks or becomes loose.
  • the spring can be fastened to or adjoining the holding edge and to an upper part of the holding arm arranged to spring load the holding arm.
  • the locking plate can comprise an outwardly extending edge which at least covers the spring partially
  • the holding arm can comprise a lip or similar that locks the fall arrest unit in a passive position before and during fitting, where the lip lies against an arm on the corner plate and is arranged to be broken off after the fitting.
  • a pressure arm can, for example, be connected via a hinge to an upper area of a part of the corner plate on the inside of the door blade, and the pressure arm stretches preferably about the corner of the corner plate to an area which adjoins one of the holding arms of the fall arrest unit, and the lower part of the pressure arm can comprise a holding edge to which at least one of the holding arms is arranged to lie against when the fall arrest unit is in a passive position because of the pull in the wire of the suspension wire.
  • Said spring means can comprise a number of springs that are arranged to the corner plate and that are set up to force the holding edge of the pressure arm to rotate the fall arrest unit so that the locking edge engages with the protrusion on the side rail if the suspension wire breaks or becomes loose.
  • a number of spring pegs can be permanently fastened to the corner plate, where each spring peg runs through an associated opening or groove in the pressure arm, and a spring plate can be arranged to the free end of the spring pegs, set up to protect/cover and to pre-stress said springs that lie between the pressure arm and the spring plate.
  • the invention also relates to a side rail of a garage door, for use with a bottom bracket as described above, where the side rail comprises a number of external, outwardly extending protrusions arranged mutually spaced apart in the longitudinal direction of the side rail, arranged to provide a friction free/mechanical connection between a locking edge of the bottom bracket and the side rail, where the outwardly extending protrusions are arranged on the wall-fastening side of the side rail.
  • the outwardly extending protrusions can be arranged with a mutual distance of between 5 and 30 cm apart.
  • the corner plate comprises a fastening means that stretches towards, alternatively at least partially beyond, the wall-fastening side of the side rail.
  • This feature does not appear in DK B 162787, as the suspension bolt DK B 162787 only extends towards the side rail, and also the fact that the placing of the side rail is of no significance for the functioning of the solution in DK B 162787. This prevents a complete protection of the wire.
  • An essential feature of the present invention is that the locking edge of the bottom bracket engages with the protrusion on the wall-fastening side of the side rail, at the same time as the bottom bracket maintains its position with respect to the side rail, due to the bottom bracket also comprising the pulley wheel that rolls in the side rail.
  • the side rail slopes about 0.5° into the garage. This leads to the garage door moving horizontally while it is opened, and it will then not slip or scrape the sealing strips. Such a slope can correspond to 26 mm for a 3 m tall garage door.
  • the present solution is independent of the thickness of the garage door. This can vary from 30 mm to 50 mm, and in said documents, in particular DK B 162787, this can result in the stopping arm being too short. In the case of DK B 162787, the length of the locking arm or the placing of the fall arrest unit must be adjusted.
  • DK B 162787 the length of the locking arm or the placing of the fall arrest unit must be adjusted.
  • a further moment of the present solution is that when the fall arrest is released, the side rail is squeezed between the pulley wheel and the locking edge. The force is directed vertically (or at an angle of 0.5°) downwards, and offers no unfortunate load on screws and the frame rail.
  • the described solutions require a strong connection between side rail and frame rail. If there is not sufficient friction in the screw connections between frame rail and side rail, or if the rails are not sufficiently rigid sideways, the distance between the locking arm and frame rail becomes so large that the fall of the garage door is not stopped.
  • the suspension point for the wire in the present invention lies almost all the way down at the floor.
  • the fall arrest does not steal lifting height for the garage door.
  • Free driving height and internal ceiling height are often limiting factors for a garage door.
  • the suspension point for the wire in the present solution is placed eccentrically with regard to the axis of rotation for the fall arrest unit and it is this which ensures that the locking edge is pulled out from the side rail when the wire is taut.
  • Figure 1 shows a first embodiment of a bottom bracket according to the present invention, fitted with regard to a side rail of a garage door, and in a passive/non-locking position.
  • Figure 2 shows a corresponding embodiment as in figure 1 , but with the bottom bracket in an active/locking position.

  • Figure 16 shows a variant of the embodiment shown in the figures 11 and 12.
  • the invention relates to a bottom bracket for fall arrest of a garage door, where the bottom bracket is arranged to a leaf of the garage door and set up to be connected to a suspension wire 52 from the spring suspension of the garage door.
  • the bottom bracket is preferably fastened to the bottom door leaf of the garage door, but can if required be arranged to other door leaves.
  • the bottom bracket comprises a corner plate 12, fastened adjoining a side edge of said door leaf, and a bolt 14 with a pulley wheel 16 fastened to the corner plate 12, arranged to roll in an adjoining side rail 50 of the garage door.
  • the corner plate, the bolt and the pulley wheel correspond in the main in the different embodiments and are therefore referred to with the same reference numbers in all the drawings.
  • the corner plate 12 is, in the main, shaped in an L-form arranged to surround the side edge of the door leaf and a suspension bolt 20,220 is fitted to the part of the corner plate that lies against the side edge.
  • the other part of the corner plate 12 comprises a fastening connection for the bolt 14 with the pulley wheel 16.
  • a first embodiment of the present invention is shown in the figures 1 to 3 and comprises a corner plate 12 with a suspension bolt 20 that extends at least partially beyond the wall fastening side of the side rail 50, where the suspension bolt 20 is connected to a rotatable fall arrest unit 22 arranged to be connected to said suspension wire 52.
  • the bottom bracket comprises spring means to rotate the fall arrest unit 22 around the suspension bolt 20 so that a locking edge 34 engages with a protrusion 54 on an adjoining side rail 50. It is sufficient that the spring force is very small.
  • the fall arrest unit 22 is preferably arranged around or adjoining a suspension bolt 20 and is rotated if the suspension wire 52 breaks or becomes loose.
  • the fall arrest unit 22 comprises at least a partial sleeve part 24 arranged to rotationally surround the suspension bolt 20, where the sleeve part comprises at least a holding arm, preferably one on either side of the outside-lying holding arm 26,28, where at least the one holding arm constitutes a wire safeguard arm, and comprises fastening means 30,32 for connection to the suspension wire 52.

  • the holding arm 28 can comprise a groove or protrusion to lie against the holding edge 40.
  • Said spring means comprises, in this embodiment, a number of springs 46, for example two pieces as shown in the figures.
