Definitions

  • This invention relates to a ventilating hatch comprising a framework surrounding the hatch opening, the longitudinal sides of the framework following a generally arcuate curve in the same direction relative to their axes, and which hatch opening so curved can be closed off with a hinged closing cover cooperating therewith.
  • a ventilating hatch of this type is known and commercially available, and used inter alia on factory roofs as a so-called "light lane", for supplying the space therebelow with light as well as for ventilation, by hinging the closing cover into the open position.
  • a drawback of such a hinging curved closing cover is that the curved surface has a considerable catch of wind when the closing cover is in the open position, there being a very substantial chance that the closing cover is torn off by gusts of wind, with all unpleasant consequences thereof.
  • Another solution could be to divide the closing cover into a plurality of separate closing members, with each closing member being hinged relative to the short side of the hatch opening. It has been experimentally demonstrated that, at least when an upright edge is provided at the longitudinal ends, this solution prevents the wind from being deflected towards the space below and allows it to accommodate to the curved surface, i.e. to pass over the opened closing members.
  • the problem involved here is opening and closing all closing members simultaneously, as the closing members are not in one straight line.
  • a possibility is to use a flexible rope which interconnects all closing members. This means, however, that for opening the closing members the rope must be pulled at one end, and for closing them it must be pulled at the other. Apart from the aesthetic aspect, such a construction is clumsy and requires additional provisions, certainly if the closing members are to be operated by remote control, for instance hydraulically.
  • the object of the invention is to overcome the drawbacks and to provide a curved ventilating hatch which, in combination with a closing cover divided into a plurality of separate closing members and a common rigid connection between the closing members, permits opening and closing of the closing members in one operation of the rigid connection, without torsion arising.
  • the closing cover consists of a plurality of separate closing members which are each hinged relative to a longitudinal end thereof about a corresponding hinge pin coupled to the longitudinal sides of the framework, said hinge pins extending parallel to the transverse side of the framework, and that, for opening and closing each of the closing members, there is provided a common pull rod whose axis follows a substantially arcuate curve, and which curve is substantially equal to the arcuate curve of the longitudinal sides of the framework, the pull rod being so arranged that it is substantially perpendicular to the hinge pins; and a plurality of connecting arms corresponding to the number of closing members, each of said arms being, on the one hand, coupled to the associated closing members and, on the other, hinged to the pull rod, the hinge joints of the connecting arms being arranged at such a location on the pull rod that, when the pull rod is pulled or pushed in the direction of its axis for, respectively, opening or closing the closing members, the centre of the arc of the pull rod is fixed substantially
  • each of the connecting arms such that their hinge joints, in the closed position of the closing members, are coupled to the pull rod at the same predetermined distance before the hinge pins of the associated closing members, as viewed in the opening direction of the pull rod, with these predetermined distances being equal to the distance from the hinge joints to the plane that is perpendicular to the pull rod and includes the hinge pins, and by providing that in the opened position of the closing members, the hinge joints are disposed at the same predetermined distance on the other side of said perpendicular planes.
  • the angle between the perpendicular plane and the line going through the corresponding hinge joint and hinge pin is approximately 40°.
  • the ventilating hatch shown in top plan view in Fig. 1 which may for instance be mounted on the roof of a building, comprises a framework 1 consisting of two opposite longitudinal sides 2 following an arcuate curve in the same direction relative to their axes, as can be clearly seen in Fig. 2, and two opposite transverse sides 3.
  • the hatch opening 4 so formed by the framework 1 is divided into a plurality of hatch compartments 6 by a plurality of profiled members 5, U-shaped with the legs directed outwardly and arranged substantially parallel to the transverse sides 3.
  • Each of these hatch compartments 6 can be closed off by a separate closing member 7 fitted in a frame section (not shown), each closing member 7 being adapted for hinge movement relative to a longitudinal end thereof about a corresponding hinge pin 8.
  • These hinge pins extend parallel to a transverse side 3 of the framework 1 and have their ends hinged to the longitudinal sides 2 of the framework 1.
  • the closing members 7 can be flat members or have a curved configuration following the arcuate curve of longitudinal sides 2.
  • each of the closing members 7 With downwardly directed rims (not shown) and a resilient sealing construction arranged around the frame section, a draught, water and snow tight seal can be obtained.
  • any water disposed on the closing members 7 can be drained laterally of the ventilating hatch via the profiled members, and thus water is prevented from entering the space below.
  • a common pull rod 9 for opening and closing the closing members, there is provided a common pull rod 9, whose axis follows a substantially arcuate curve and is substantially equal to the curve of the longitudinal sides 2 of the framework 1.
  • the pull rod 9 is arranged such that it extends coaxially with the longitudinal sides 2, and hence with the series of closing members 7, and substantially perpendicularly to the hinge pins 8 of the closing members 7.
  • Via a plurality of substantially identical connecting arms 10 the pull rod 9 is coupled to the corresponding closing members 7.
  • the connecting arms are, at one end, rigidly coupled to the closing members, and, at the other, hinged to the pull rod 9 at hinge joints 11.
  • the connecting arms 10 are so constructed that, in the closed position of the closing members, the hinge joints 11 of the arms 10 on the pull rod 9 are disposed at the same predetermined distance before the hinge pins 8 of the corresponding closing members 7, as viewed in the opening direction of the pull rod (direction of arrow P).
  • Fig. 3 shows that the predetermined distance equals the distance 'a' from the hinge joints 11 to the plane 12 which is perpendicular to the pull rod 9 and includes the hinge pin of the associated hinge joint, and that, in the opened position of the closing members, the hinge joints are disposed at the same predetermined distance 'a' on the other side of these perpendicular planes 12.
  • the hinge joints are at a distance 'a' such that the angle ⁇ between the perpendicular plane and the line going through the hinge joints 11 and the associated hinge pins 8 of the closing members 7 is approximately 40°, which means that the closing members 7 can be opened through an angle of approximately 80°. It will be clear that the angle ⁇ can have other desired values.
  • the pull rod 9 although it will first come down slightly since the hinge joints 11 traverse circular paths b during their displacement- after completion of an opening or closing movement, will invariably end up at the same radial distance R from its fixed centre, i.e. that the centre of the arc of the pull rod is in the same point before and after the opening and closing movement.
  • the pull rod 9 can be simply driven by for instance a hydraulic drive 13 which can be arranged adjacent the ventilating hatch and which can be remote-controlled.
  • the drive 13 can be effected electrically, pneumatically or by hand.
  • the pull rod 9 can be arranged in the middle of the ventilating hatch or on one side or on both sides, for instance when the ventilating hatch has very large dimensions.
  • the closing members 7 can be so arranged that they overlap. In that case, the provision of profiled members 5 can be omitted.
  • end partitions 14 which are arranged at the two transverse sides 3 of the framework 1. These end partitions need only be of limited height to enable sufficient deflection of the wind and certainly need not project above the highest closing members 7. If necessary, also longitudinal partitions (not shown) can be arranged at the two longitudinal sides 2 of the framework 1, for instance to meet local fire security regulations.
