Definitions

  • This invention relates to windows and in particular to windows of the type herein referred to as turn-tilt windows comprising a fixed frame and a sash mounted thereon by a turn and tilt mechanism for pivotal movement about a vertical axis for operation in the turn mode and about a horizontal axis for operation in the tilt mode with the axis of pivotal movement being selected by a control handle operably connected to the turn and tilt mechanism.
  • the sash is fitted to tilt from the bottom of the frame and to turn from the side of the frame.
  • Operation in the tilt mode provides limited opening movement at the top of the window sufficient for normal ventilation purposes but insufficient to allow a person, in particular a child to fall outwards through the opening.
  • Operation in the turn mode provides unrestricted opening movement and allows access to both sides of the window from the inside for cleaning purposes.
  • the windows are therefore particularly suited for use above ground level and in particular in high rise buildings by allowing safe ventilation with the facility for cleaning the window from the inside.
  • the control handle is operable to fasten the sash in the closed position and is rotatable from the fastened position to a first operative position for operation of the sash in the turn mode and a second operative position for operation in the tilt mode.
  • the first and second operative positions are usually obtained by rotation of the control handle through 90° and 180° respectively from the fastened position.
  • the control handle may optionally have a third operative position which also permits operation in the tilt mode to provide a small degree of opening movement at the top of the window for permanent or night ventilation purposes. Where provided, the third operative position is intermediate the first and second operative positions and is obtained by rotation of the control handle through 135° from the fastened position.
  • a disadvantage of such handle operation is that the turn mode is obtained first on rotation of the control handle and the tilt mode is only obtained after rotation of the control handle beyond the operative position for the turn mode. Accordingly, there is a risk, in service, of the turn mode being inadvertently selected. This presents a serious safety hazard particularly in the case of operation of the control handle by a child.
  • a turn-tilt window of the kind herein referred to wherein the control handle is operable to fasten the sash in a closed position and is rotatable from the fastened position to a first operative position for operation of the sash in the tilt mode and a second operative position for operation of the sash in the turn mode, the second operative position being selected by rotation of the control handle beyond the first operative position and, a safety device to permit rotation of the control handle to the first operative position but restrict rotation of the control handle to the second operative position, the safety device being manually releasable to allow rotation of the handle to the second operative position.
  • the normal operation of the control handle to select the turn and tilt modes is reversed so that the tilt mode is obtained first on rotation of the handle and a safety device is provided which prevents rotation of the handle to obtain the turn mode until the safety device has been released.
  • the tilt mode may be selected at all times but the turn mode may only be selected after the safety device has been released.
  • the window may be operated in the tilt mode providing limited opening for normal ventilation purposes by all users but inadvertent operation in the turn mode providing unrestricted opening with access to both sides of the window for cleaning purposes is precluded. Consequently, the afore-mentioned safety hazard, to children especially, resulting from unrestricted opening of the window in the turn mode is considerably reduced.
  • the safety device is manually movable from a limit position in which rotation of the control handle in a first sense to select the turn mode is precluded to a release position in which rotation of the control handle in the first sense to select the turn mode is permitted.
  • the safety device is resiliently biassed to the limit position, for example by a spring.
  • the safety device is automatically re-set in the limit position on rotation of the control handle in the opposite sense from the second operative position.
  • the turn and tilt mechanism includes pivot connections between the sash and frame for controlling opening movement in the tilt and turn modes and a drive mechanism extending around the peripheral edge of the sash for controlling the combination of the pivot connections for operation in the turn and tilt modes.
  • the control handle is coupled to the drive mechanism and, on rotation of the control handle, is operable to displace the drive mechanism around the sash to select the required combination of the pivot connections for operation in the turn and tilt modes.
  • the drive mechanism preferably includes means operable to prevent rotation of the control handle when the sash is in an open position.
  • the user is prevented from selecting a different mode of operation when the sash is open and the sash must first be moved to the closed position before the control handle can be rotated. In this way, operation of the drive mechanism to obtain the required combination of the pivot connections is ensured.
  • the safety device is mounted behind a face flange of the sash and is accessible only when the sash is in an open position. In this way the safety device cannot be released when the sash is in the closed position and the control handle must be rotated to the first operative position to enable the sash to be opened in the tilt mode for the safety device to be released.
  • the safety device comprises a slider mounted on the sash for limited sliding movement thereon and a fixed stud mounted on the drive mechanism for movement therewith relative to the slider.
  • the fixed stud is engageable with the slider in the limit position to prevent displacement of the drive mechanism to select the turn mode and the slider is movable to the release position to free the stud and permit displacement of the drive mechanism to select the turn mode.
  • the engagement of the fixed stud and slider in the limit position of the safety device corresponds to a third operative position of the control handle intermediate the first and second operative positions in which opening movement in the tilt mode is permitted.
  • opening movement in the third operative position is restricted by engagement of a lug mounted on the drive mechanism with a retainer mounted on the frame to provide a small degree of opening movement for permanent or night ventilation.
  • the slider has a bifurcated portion having a lead-in part and a narrower tail part and the fixed stud has a shank slidable in both parts and a stud collar slidable in the lead-in part only.
  • the resilient biassing acts between the slider and the sash to bias the slider to the limit position in which the stud collar is received in the lead-in part and permits rotation of the control handle until the stud collar abuts the slider at the end of the lead-in part.
  • the slider is moved to the release position by depressing against the resilient biassing and sliding lengthwise relative to the fixed stud to locate the stud shank in the tail part whereupon further rotation of the control handle is permitted.
  • a window I comprising a fixed frame 2 and a glazed sash 3 mounted thereon by a turn and tilt mechanism 4 operable by a control handle 5 mounted on the sash 3 to select operation of the window I in a turn mode or a tilt mode and, a releasable safety device 6 mounted on the sash 3 to prevent selection of the turn mode until the safety device 6 has been manually released.
  • the turn and tilt mechanism 4 includes a fixed pivot 7 and a releasable pivot 8 connecting the bottom of the sash 3 to opposed lower corners of the frame 2 and, a scissors stay 9 connecting the top of the sash 3 to an upper corner of the frame 2 vertically above the fixed pivot 7.
  • the scissors stay 9 is pivotally connected to the frame 2 and may be locked in the folded position to provide a fixed pivot.
  • the releasable pivot 8 For operation of the window 1 in the tilt mode, the releasable pivot 8 is engaged to permit pivotal movement of the sash 3 from the bottom of the frame 2 about a horizontal axis and, for operation of the window 1 in the turn mode, the releasable pivot 8 is disengaged and the scissors stay 9 is locked in the folded position to provide a fixed pivot to permit pivotal movement of the sash 3 from the side of the frame 2 about a vertical axis.
  • the turn and tilt mechanism 4 further includes a drive mechanism 10 comprising respective elongate bars 11,12,13,14 slidably mounted on each side of the sash 3 in a groove 15 extending around the peripheral edge of the sash 3 with the adjacent ends of the bars on adjoining sides of the sash 3 being connected at three comers of the sash 3 by flexible strips 16,17,18 for transmitting the drive to successive bars around the sash 3.
  • a drive mechanism 10 comprising respective elongate bars 11,12,13,14 slidably mounted on each side of the sash 3 in a groove 15 extending around the peripheral edge of the sash 3 with the adjacent ends of the bars on adjoining sides of the sash 3 being connected at three comers of the sash 3 by flexible strips 16,17,18 for transmitting the drive to successive bars around the sash 3.
  • the bars 11,12,13,14 are retained in the groove 15 by a cover plate designated 19,20,21,22 and are provided with one or more locking members 23, for example bolts, rollers or the like, which project outwardly through slots 24 in the overlying cover plate for releasable engagement with fixed keepers 25 on the frame 2 to fasten the sash 3 in a closed position.
  • the drive mechanism 10 is concealed behind a face flange 26 of the sash 3 and is not visible when the sash 3 is closed thereby providing a neat finish and preventing tampering with the drive mechanism 10.
  • the control handle 5 is coupled to the drive mechanism 10 by a rack and pinion.device 40 for converting rotary movement of the control handle 5 into linear displacement of the bars 11,12,13,14 around the sash 3 to disengage the locking members 23 from the keepers 25 and select the required combination of the pivots 7,8 and scissors stay 9 for operation of the window I in the turn and tilt modes.
  • the control handle 5 is rotatable from the fastened position shown in Figure 1 in which the sash 3 is closed to first and second operative positions in which the sash 3 may be opened in the tilt mode and the turn mode respectively.
  • the first and second operative positions correspond to rotation of the control handle 5 through 90° and 180° respectively from the fastened position.
  • opening movement of the sash 3 in the tilt mode is controlled by the scissors stay 9 and the full extension of the stay 9 is such as to provide an opening at the top of the window sufficient for normal ventilation purposes but insufficient for a person, especially a child, to pass through the opening.
  • the sash 3 In the second operative position of the control handle 5 shown in Figure 3, the sash 3 is free to open inwards in the turn mode providing access to both sides of the sash 3 to facilitate cleaning and a wide opening through which a person may pass to facilitate escape in an emergency, e.g. in a fire.
  • control handle 5 In addition to rotation to the first and second operative positions, the control handle 5 is rotatable to a third operative position, intermediate the first and second operative positions in which the sash 3 may also be opened in the tilt mode.
  • the third operative position corresponds to rotation of the control handle 5 through 135° from the fastened position.
  • opening movement of the sash 3 in the tilt mode is limited by the engagement of a lug 27 mounted on the drive mechanism 10 in a retainer 28 mounted on an upper comer of the frame 2 vertically above the releasable pivot 8.
  • the retention of the lug 27 in the retainer 28 enables the sash 3 to be opened a safe small amount for permanent or night ventilation purposes.
  • the drive mechanism 10 also includes means - (not shown) to prevent rotation of the control handle 5 when the sash 3 is in an open position and thereby prevent the user selecting a different mode of operation when the window I is open.
  • Such means may be of any known type and ensures that the required combination of the pivots 7,8 and scissors stay 9 for the turn and tilt modes is always obtained.
  • the safety device 6 for preventing selection of the turn mode until the safety device 6 has been released is shown and comprises a slider 29 and a fixed stud 30 mounted on the side of the sash 3 adjacent to the upper corner of the frame 2 above the releasable pivot 8.
  • the safety device 6 is concealed behind the face flange 26 of the sash 3 and is not visible or accessible when the sash 3 is closed thereby preventing tampering with the safety device 6.
  • the slider 29 is mounted on the cover plate 20 for limited sliding movement lengthwise of the cover plate 20 by means of a headed rivet 31 fixed to the cover plate 20 and extending through a slot 32 in the slider 29.
  • the fixed stud 30 is mounted on the underlying bar 12 of the drive mechanism 10 and projects outwards through an elongate opening 33 in the cover plate 20 for reception in a bifurcated portion 34 of the slider 29.
  • the bifurcated portion 34 is in two parts having a wide lead-in part 35 and a narrow tail part 36.
  • the stud 30 has a shank 37 slidable in both the lead-in and tail parts " 35 and 36 respectively of the bifurcated portion 34 of the slider 29 and, a collar 38 is provided on the shank 37 which is slidable in the lead-in part 35 only.
  • a spring 39 mounted on the rivet 31 acts between the cover plate 20 and the underside of the slider 29 to bias the slider 29 to a limit-position shown in Figure 6 in which the stud collar 38 is received in the lead-in part 35.
  • the slider 29 is manually movable to a release position shown in Figure 7 in which the stud shank 37 is received in the narrow tail part 36 of the bifurcated portion 34 by depressing the slider 29 against the bias of spring 39' to raise the bifurcated portion 34 above the stud collar 38 and sliding the slider 29 towards the stud 30.
  • the safety device 6 In the fastened position of the control handle 5, the safety device 6 is in the limit position with the stud collar 38 received in the lead-in part 35 of the bifurcated portion 34 of the slider 29.
  • the drive mechanism 10 On clockwise rotation of the control handle 5 from the fastened position, the drive mechanism 10 is actuated and the bar 12 of the drive mechanism and the stud 30 mounted thereon are displaced relative to the slider 29 causing the stud collar 38 to move along the lead-in part 35 towards the tail part 36 of the bifurcated portion 34.
  • such rotation is permitted up to 135° so that both the first and third operative positions of the control handle 5 for operation of the window I in the tilt mode for normal and permanent or night ventilation may be freely selected without hindrance from the safety device 6.
  • control handle 5 In order to select operation in the turn mode, it is necessary to rotate the control handle 5 to the first operative position, open the sash 3 in the tilt mode to gain access to the safety device 6, release the safety device 6 as described so that the stud shank 37 is located in the tail part 36 of the bifurcated portion 34 of the slider 29 and close the sash 3 whereupon the control handle 5 may be rotated to the second operative position as shown in Figure 10.
  • the stud 30 will again be displaced relative to the slider 29 causing the stud shank 37 to move along the tail part 36 towards the lead-in part 35 of the bifurcated portion 34 of the slider 29.
  • the stud 30 is again located in the lead-in part 35 and the slider 29, under the bias of spring 39, positions the stud collar 38 in the lead-in part 35 thereby automatically re-setting the safety device 6 in the limit position and preventing re-selection of the turn mode until the safety device 6 has again been released.
  • the invention is not limited to the embodiment above described, for example while a drive mechanism consisting of elongate bars positioned along the sides of the sash and connected by flexible corner strips has been described, other known constructions of drive mechanisms including a length of wire extending around the sash to which the associated elements are secured may be used.
  • a third operative position of the control handle intermediate the first and second operative positions for a permanent or night ventilation facility as above-described is optional and may be omitted. If the third operative position is omitted, the engagement of the stud and slider to prevent rotation of the control handle to select the turn mode may be arranged to correspond to the first operative position of the control handle.
  • the control handle may be rotatable in the counterclockwise direction from the fastened position to select the operation in the tilt and turn modes.
  • the safety device may be mounted on the sash at different positions, for example on the top of the sash.
