Definitions

  • the invention relates to a tilt-and-turn window for a sloping roof provided with a case near the top rail of which two arms are pivotably attached, a window being mounted in a tilt-and-tum manner between the said arms in a manner such that the outer face of the window can be turned inwards and means being present to take the weight of the window which has been brought to an open position by pivoting the arms upwards.
  • a window of this type is known from GB-A-2,005,330. Advantages thereof are that the hinge around which the window can rotate to the open position is relatively high and consequently the so-called standing height is relatively large when the window is in the fully open position, and that the outer face of the window can be tilted and turned to a position in which the said face can be washed from the roof space.
  • each of the two arms has a separate hinge hub with respect to the case.
  • the arms are not constrained to move synchronously, which results in an increased risk of the window twisting when it is opened and closed.
  • the spring construction chosen adjustment of the window may proceed less smoothly than is desired.
  • the operating reliability is at risk.
  • the object of the invention is to provide a tilt-and-turn window as described in the introduction which is smoothly and infinitely adjustable without clicking noises, which is stable in any position, which is robust and operationally reliable in construction and which can easily be matched to the roof slope in relation to taking the weight of the opened window.
  • the tilt-and-turn window is characterised in that the said arms are combined to form an auxiliary frame by means of a coupling tube mounted in a pivotable manner in the case, and to take the weight of the opened window at least one pretensioned, spirally wound bending (torsion) spring is mounted around the coupling tube, and that adjustable means of friction are present to compensate for differences in the desired and delivered spring force.
  • the spirally wound bending spring can have a relatively large length without difficulty.
  • a tie rod extends through the coupling tube and there is a tensioning nut screwed to one or both ends of the said rod.
  • the auxiliary frame formed by two arms and the coupling tube must form a rigid whole to avoid twisting of the window and to effect a synchronous pivoting of the arms.
  • the window In the maximally opened position the window can be tilted and turned into the washing position. If this tilting and turning is desired, the auxiliary frame will preferably be temporarily fixed in the said maximally opened position. This means that during the time in which the window is locked against tilting and turning, there must be no locking of the auxiliary frame in the maximally opened position, while con- versety the locking of the window with the auxiliary frame in the maximally opened position must take place if the window has to be able to be tilted and turned. In view of this it is preferable that a locking bar is displaceable between a first locking position in which the window is locked with a certain play with respect to the auxiliary frame and a second locking position in which the maximally opened auxiliary frame is locked with respect to the case.
  • one end of the torsion spring may be fixed in an opening in the case while the other end thereof is connected to a spring dowel which is mounted in a rotatable manner around the coupling tube and which can be rotated by means of a tensioning key to a position in which a locking element to be fitted locks the spring dowel with respect to the coupling tube.
  • the tiit-and-tum window construction depicted for a sloping roof comprises a case 1 usually consisting of wood and a glazed window 2 which is mounted in a-titt-and-tum manner on tilt-and-turn joints 3.
  • the said tilt-and-turn joints are joined to an auxiliary frame 4 which has a hinged joint at 5 to the case arms 6 which are solidly attached to the case 1.
  • at least one fixing element 7 is pivotably mounted at the position of the fit-and-tum joints 3. This element can act in conjunction with a pin 8 secured to the frame.
  • the auxiliary frame 4 comprises two auxiliary frame arms 9 which over the greater part of their length have a U-shaped construction and which are connected to a coupling tube 12.
  • the connection is effected as a result of the fact that pegs 11 extending axially from the end covers of the coupling tube engage in openings of the arms 9.
  • a tie rod 13 Through the said tube 12 there extends a tie rod 13, the ends of which each project through a case arm 6.
  • a tensioning nut 1 0 is screwed to these ends which are provided with a screwthread, the tensioning force being transferred via a cup spring 14 to the frame arm 6.
  • Friction rings 15 are mounted between the case arms 6 and the auxiliary frame arms 9.
  • each end of the coupling tube there extends a spiral torsion spring 16, one end of which is fixed in an opening of a case arm and the other end projects into a socket 17 which forms part of a spring dowel 18 which is mounted in a rotatable manner around the coupling tube 12.
  • a part of the spring dowel 18 is provided with teeth 19 punched outwards with which a tensioning key 20 ( Figure 5) can interact in order to pretension the respective spring.
  • the springs can be locked by means of a locking element 21 which is inserted through openings of the spring dowel 18 8 and the coupling tube 12 which lie in line.
  • the pretension of the springs 16 delivers a force which can compensate for the weight of the combination of auxiliary frame 4 and window 2 when pivoted open.
  • the so-called standing height below the window is large.
  • the maximum opening of the window is determined by stop protrusions 22 which the end 23 of the bent part of the U-shaped auxiliary frame arms 9 comes up against. After unlocking the window with respect to the auxiliary frame, it can be tilted and turned in the maximally open position to a position in which the outer face of ' the glazing is turned inwards and can be washed.
  • a locking bar 24 which can be moved backwards and forwards by means of an operating lip 25 inside a guide bush 26 from a first locking position depicted in Figure 4, in which an end of the locking bar 24 projects with play into a chamber 28, bounded by an angle iron 27, in the window, and a second locking position in which the other end projects into the space above the case arm 6 in the maximally open position of the window.
  • the window is joined to the coupling tube 12 in the first locked position with a certain play.
  • the locking bar can be brought into the second locking position in which the coupling tube is linked to the case on the one hand by the lock and on the other hand by the stop protrusion 22.
  • the play with which the end of the bar 24 projects into the chamber 28 in the first locked position is desired so that the window 2 can seat in the most favourable sealing position on being closed.
  • the sealing elements are indicated by 29.
  • the double glazing is indicated by 31.
  • two reinforcing linings 32 are fitted between the coupling tube and the spring dowel.
  • the fixing screws for fixing the case arms 6 to the case 1 have the reference figure 33.
