Definitions

  • the present invention relates to an improved roller shutter handling member support.
  • the present invention relates to an improved support integrated in a side of the box in which is arranged the roller shutter to which is constrained a handling winch for the roller shutter.
  • a widespread type of closing device for windows and door windows consists of a roller shutter made up of a plurality of small wood or metal slats connected together.
  • the roller shutter unwinds from a roller arranged in a box to which are connected the handling members which permit moving the shutter.
  • Said handling is achieved by different alternative systems consisting for example of a belt connected to a pulley through a powered unit or by a winch in which is engaged the end of a rod with jointed crank.
  • the winch is constrained to one of the elements or sides which make up the heads of the box in relation to which it must have precise overall dimensions.
  • the winch must not project beyond the internal edge of the box side and must have a thickness conventionally within the standard dimension of 24mm.
  • Said box is sometimes fitted on the inside face with a plate of suitable thickness forming the base for connection of the winch.
  • the plate is provided with two or more threaded holes for as many screws emerging from the handling member and is made integral with the internal wall of the box side by different systems.
  • the plate be connected to the side by means of rivets, screws or similar members which are engaged from the exposed face of the side.
  • Said system involves aesthetic and functional shortcomings.
  • the rivets or screws which remain visible on the exposed face of the box side alter the appearance of the equipment in a significant manner.
  • the projection of said means of retention although limited, can also create problems during installation of the box where said box must be inserted in an opening already formed with precise measurements.
  • WO-A- 8806672, DE-A-3501767 and NL-A-6813763 disclose window blind supports.
  • the purpose of the present invention is to overcome the above shortcomings.
  • the purpose of the present invention is to provide an improved support for roller shutter handling members which would allow accurate, fast and steady housing of the members and in particular standardised winches along the internal wall of one of the box sides.
  • Another purpose of the present invention is to provide an improved support as defined above which would not require drilling of the front wall of the box side with resulting engagement from the outside in the holes created by winch retention means.
  • Another purpose of the present invention is to make available to users an improved support capable of providing a high degree of strength and reliability in time such as to also be easily and economically produced.
  • the improved support for roller shutter handling members which is the object of the present invention and is characterised in that it displays integrally secured to the internal wall of at least one side of a roller shutter box by means wholly within the box a plate or shaped flange defining a seat for partial or total reception of a winch provided with diametrically opposed apertures surrounded by lowered portions on one or both faces, the whinch being secured to the plate by securing means passing through the apertures into portions of the plate behind the winch and the lowered portions on the side adjacent the plate having a depth substantially equal to the thickness of the plate portions behind it such that these portions are recessed into the winch and in other areas the winch contacts the internal wall.
  • the improved support for roller shutter handling members which is the object of the present invention and designated as a whole by 10 consists of a plate or shaped flange 12 constrained to the internal wall 14 of the side 16 of a conventional roller shutter box (not shown) and a winch 18 which has in diametrically opposite positions two identical depressions 20 achieved on both faces.
  • the flange 12 is provided preferably although not critically of thermoplastic material and displays a peripheral external configuration tending to trapezoidal and limited thickness.
  • said external configuration of the flange 12 defines above a straight sector 22 having preferably reduced length in relation to the width of the internal wall 14 of the side 16 from which there extend downward opposing branches 24, 26 substantially in L shape.
  • Along the straight sector 22 are achieved two or more bores in which are engaged under pressure corresponding cylindrical projections 28 integral with the internal wall 14 of the side 16 and achieved in a single piece therewith during forming.
  • the above mentioned projections are provided near a sector of the peripheral edge 28' of the side 16 against which butts the straight sector 22 of the flange 12 when same is engaged through the above mentioned bores on the projections 26.
  • the branches 24, 26 extending downward from the upper sector 22 are opposed mutually toward the conventional pivot 30 which projects from the centre of the internal wall 14 of the side 16 to constitute the connection member for a known connector 32 which is connected to and supports the roller shutter shaft shown diagramatically at 34.
  • the flange 12 displays advantageously a semicircular internal profile 36 repeating partly the peripheral form of a winch 18. The outside diameter of the latter is slightly less than that of the seat defined by the internal profile 36 of the flange 12.
  • the winch 18 in accordance with another characteristic of the present invention is provided with diametrically opposed lowered portions 20 which are preferably achieved on both the opposite faces of the winch 18 opposite the conventional shaped through recesses 38.
  • said portions are lowered by a limited amount substantially corresponding to the thickness of the bent back ends of the branches 24, 26 which oppose each other towards the pivot 30 and have a bore 40.
  • the thickness of the above mentioned branches is between 4 and 7 mm and is less than that of the upper sector 22 of the flange 12 from which the branches extend.
  • the lowered portions 20 display preferably an upward extension above that of the through recesses 38 which are completely delimited by them.
  • the winch 18 On the winch 18 in a central position is formed the usual hexagonal seat for reception of the connector 32 of known type which from one side engages in the pivot 30 of the side 16 and on the other side connects with the head of the shutter roller 34.
  • the through recesses 38 In the through recesses 38 are arranged generic screws 42 which, projecting from the rear face of the winch 18, screw into the bores 40 formed on the bent back portions of the branches 24, 26 of the flange 12.
  • Assembling the entire improved support which is the object of the present invention involves simple and rapid operations starting with positioning of the flange 12 on the internal wall 14 of the side 16.
  • the projections 28 formed on said side are engaged in the holes created along the upper sector 22 of the flange.
  • the winch 18 is arranged in the semicircular seat 36 defined by the internal profile of the flange 12 and, through the screws 42 inserted in the recesses 38, is constrained to the bent back branches 24, 26 of the flange. Said ends butt opposite the lowered portions 20 created on the winch 18 while the remaining sector of the winch which is not lowered encounters the internal wall 14 of the side 16.
  • the improved support which is the object of the present invention allows coupling and constraining rapidly the handling members of the shutter to the box side while holding predominantly a total thickness of said member and in particular a winch equivalent to the depth of said side. There is simultaneously avoided the ill appearing use of retention means engaged from the outside in the side.
  • the winch can also be advantageously applied to the right side or left side of the box depending on different requirements.
  • the flange to which is constrained the winch can have a configuration and/or extension different from that described and illustrated by way of example.
  • Said flange can also be provided with preimpressed and removable sectors along the internal and/or external profile to adapt it to sides or winches of different dimensions.
  • the handling member to which is made principal reference consists of a winch but it is intended that said construction plan could concern different handling members such as for example power units.
