Definitions

  • the present invention relates to a system for balancing the weight of the closure element of sectional doors and to a sectional door provided with such system.
  • the weight balancing system according to the invention may be used in particular for the production and assembly of vertically sliding sectional doors, for civil and industrial use.
  • a sectional door comprises a plurality of modular slats longitudinally hinged to each other to form a closure element and inserted in a sliding manner at both longitudinal ends in dedicated lateral guides.
  • DE 196 51 067 A1 discloses such a sectional door.
  • the closure element is moved between a closed position, in which it is lowered in relation to the aperture to be closed (normally vertically positioned), and an open position, in which the element is raised in relation to the aperture (normally horizontally positioned).
  • each lateral guide comprises two sections angled to each other and associated by an angular connection section.
  • a first section (usually vertical) is positioned at the aperture to be closed and houses the element when closed.
  • a second section (usually horizontal) is positioned above the first vertical section (for example near the ceiling of the room to be closed) and houses the element when open.
  • a sectional door is provided with a system for balancing the weight of the closure element, active during both the raising and lowering phases of the closure element.
  • the system relieves the motorised system used for such movement (where provided) or manual hoisting system, of the weight of the closure element.
  • a first type of balancing system uses traction springs.
  • the springs are positioned along the lateral guides and are mechanically connected to the closure element by means of a complex system of cables and pulleys in such a way that the lowering of the closure element place the springs in traction, balancing the weight.
  • a compression spring may be used as disclosed in DE 196 51 067 A1 .
  • a second type of balancing system uses torsion springs.
  • the springs are positioned on a shaft placed transversally to the two lateral guides.
  • the closure element is mechanically connected to the springs by means of a complex system of cables and pulleys positioned along the guides and connected to the support shaft by dedicated cable winding drums.
  • the system is structured so that the lowering of the closure element in itself loads the springs, balancing the weight.
  • the purpose of the present invention is to eliminate the drawbacks of the prior art mentioned above, by providing a system for balancing the weight of the closure element of sectional doors which is simpler in terms of mechanics and construction.
  • a further purpose of the present invention is to make available a system for balancing the weight of the closure element of sectional doors which is mechanically safer and more reliable.
  • a further purpose of the present invention is to make available a system for balancing the weight of the closure element of sectional doors which is easy and cheap to produce.

  • reference numeral 1 globally denotes a system for balancing the weight of the closure element of sectional doors according to the invention and reference numeral 100 denotes a sectional door provided with such balancing system.
  • the system for balancing the weight of the closure element 110 of sectional doors comprises a support structure 2 and at least one compression spring 11, 12, which is supported by the support structure 2 and can be mechanically connected to the closure element of a door so as to be compressed during the downward, closing movement of the closure element 110 and so as to be decompressed during the raising, opening movement of the closure element.
  • the spring balances the weight of the closure element with its spring force.
  • the spring is in compression exerting a spring force which balances the weight of the closure element.
  • the spring is in decompression continuing to balance the weight of the closure element.
  • this may facilitate raising of the closure element when opening, given that it relieves the manual or motorised movement from the weight of the closure element.
  • the balancing system 1 is provided with one or more compression springs, positioned in different configurations, and in particular, associated to each other coaxially in the direction of the spring effect or positioned in parallel pairs.
  • spring is taken to mean in general both the case of a single spring and the case of configurations of two or more springs.
  • the spring 11, 12 is of the helical type, for example in steel.
  • other type of compression spring suitable for the purpose may also be used.
  • the support structure 2 of the balancing system 1 may be associated or directly incorporated into the weight-bearing frame of a sectional door 100 (in particular in correspondence of a lateral guide) or in any case positioned near the door to enable the associated spring to be connected to the closure element 110 of the door 100.

  • the pusher element 22 is provided with a lever mechanism 23 for connection to the closure element 110 of the door 100.
  • the aforesaid lever mechanism 23 is designed to transfer the movement of the closure element 110 to the pusher element 22 in such a way that the downward movement of the closure element 110 corresponds with a movement of the pusher element 22 towards the stop element 21 and therefore a compression of the spring 11, 12 against the stop element 21 of the support structure 2.
  • Such compression is able to generate an opposite thrust (spring force) able to balance the weight of the closure element.
  • the pusher 22 is distanced from the stop element 21, drawn by the closure element.
  • the spring 11, 12 is therefore free to decompress, exerting a thrust (spring force) on the pusher 22, concurring with the movement imposed by the closure element, so as to keep the weight of the closure element 110 constantly balanced.
  • the pusher element 22 receives the thrust deriving from the spring force of the spring 11, 12 in compression and transmits it to the closure element 110 via the lever mechanism, balancing the weight of the closure element.
  • the pusher element 22 receives the thrust deriving from the spring force of the spring 11, 12 in decompression and transmits it to the closure element 110 via the lever mechanism, balancing the weight of the closure element.
