Definitions

  • This invention relates to a fastening device and is particularly, though not exclusively, concerned with a fastening device for locating and fastening an article in a structure defining an opening e.g. a window frame in an opening in a wall, or a door in a jamb.
  • the invention has particular application for the fitting of pre-assembled complete window units comprising a frame and fitted glazing.
  • multi-glazed windows are nowadays usually pre-assembled in a factory, in various sizes suited to customer needs.
  • factory made units it is easier to ensure the proper hermetic sealing, and it is often easier in a factory to make such units individually to a size to fit readily into a measured opening. It is then necessary to ensure that the window units remain located in the window opening.
  • the sub-frame is slit, to provide in one embodiment a tongue piece "f" (Figs 1/2) which lies generally transverse to the window fitting direction, and parallel to the plane of the window frame; at one transverse end this tongue piece is bulged outwardly to form a catch.
  • Fig.3/4 the sub-frame is again slit, to provide a tongue piece which lies generally parallel to the window fitting direction; the tongue piece has been pressed outwardly to form the required catch.
  • both catches are formed from the sub-frame by slitting of the metal, it is suggested that these catches are "resilient", so that they can not only be deformed by the window frame during fitting but will thereafter move back, respectively parallel to the plane of the window frame and to the outwardly pressed position; this suggestion of resilience would be rejected as improbable with the
  • the device is provided on one (side) frame member only, not on all (four) side frame members of a rectangular window frame.
  • the device is designed to allow the opening window to move repeatedly transversly to the device tongue(s) during window opening and closing.
  • the device is not formed integrally with the window, but is a separate component mounted between the window and window frame, and affixed to the window frame.
  • the de Vries inner and outer window frames are shown as extruded (plastics) structures, giving continuity along the length of the components and dimensional accuracy, but utilise second (tongue) parts cut or punched out of the face of the fastening device.
  • De Vries did not recognise the advantage of forming the fastening device integral with the outer periphery of the (outer) window frame for permanent frame retention in an opening, with a reduced number of components, increased dimensional accuracy, reduced complexity and cost in fitting, and reducing "wasted" space in the window opening (a significant part of which is covered by the disclosed retention means for the outer frame).
  • the inward stop for the window frame could advantageously be formed separately e.g. of top-hat form or by plates nailed to the reveal, each plate having an upstanding end part which when the plate 'is correctly positioned provides an inward abutment, secured to the reveal or window opening prior to fitting of the window unit into position.
  • an improved fastening device for securing an article (such as a window unit) adjacent a surface (such as a surface of a structure defining a window opening) which includes a gripping member which can be resiliently deflected by the article during fitting and which can thereafter engage the article to inhibit subsequent removal.
  • a fastening device for securing two members against relative movement in one selected direction characterised in combination by a first device part mounted upon and movable with one of the members and a second device part engageable with the other of the members, the second device part being resiliently deflectable towards said one of the members to permit relative movement between the members in a direction opposed to said one selected direction, the second device part being coupled to the first device part such that movement of the said one of the members in said selected direction can be resisted by the other of the said members, the said one of the members having a surface upon which the first device part is mounted, the said one of the members being a window component, the first device part being integral with the said window component, the said other of the members comprising a face of a window opening, the said surface facing outwardly of the opening and towards said face.
  • the second device part is a tongue tip, the tongue being formed integrally with the component (window frame) and angled thereto.
  • the tongue tip is serrated; and in a typical embodiment used for installing pre-assembled and glazed window units, the fastening device will include a first tongue extending at a first angle from the frame, and a second tongue extending at a greater angle and to the same side of the frame, the tip of the second tongue having serrations which are more pointed than those of the tip of the first tongue, and able to grip against hard surfaces without appreciable slippage.
  • the second tongue usefully has a first portion at the said greater angle to the plane of the plate and a second portion at a still greater angle, with the second portion including the tongue tip; in this embodiment, the tip (on the second tongue portion) may conveniently extend slightly further away from the plate than the tip of the first tongue, so that the second tongue can be the first to engage e.g. the masonry defining the reveal, and so that this engagement will be at an angle nearer to the perpendicular to the plate (and so usually to the masonry) than will be the engagement angle for the first tongue.
  • first and second tongues are separated laterally by an intermediate portion of the first device part, so that if the window unit and the structure defining the opening are not exactly square one to the other, at least one of the tongues can engage the opening structure i.e. with the fastening device integral with the unit.
  • the first and second tongues are axially spaced one from the other so that at least one can engage the opening structure.
  • the tongues can be positioned fore and aft or side by side or where more than two tongues or gripping members are provided.
  • fastening devices as herein disclosed can be made integral with the structure forming the opening, prior to the insertion of a pre-assembled (ready-glazed) window unit, this is not the preferred arrangement since the fastening devices have to be secured e.g. in a window opening, individually on site.
  • the fastening devices are integral with the window frame (with device formations on at least two sides thereof) i.e. preformed as part of the window frame - as when this is a plastics extrusion; for this preferred arrangement the tongue tips can locate arid fasten the respective window unit by engageing the respective surface(s) of the structure defining the opening.
  • the window frame is resiliently sprung within that structure defining the opening, so allowing a peripheral gap in which the frame can expand and contract e.g. with ambient temperature variations.
  • the peripheral gap between the frame and e.g. the masonry can be filled and sealed with known proprietary sealing products in the normal manner.
  • an accessory comprising transverse retaining slots (holes or depressions depending on the thickness of the accessory), the accessory being fixable to the structure at a position where it can be engaged by a tongue tip, in use.
  • This accessory conveniently a flat plate, can itself be modified so as to include a central (longitudinal) aperture running generally perpendicular to the transverse slots which in one embodiment stop short of the aperture to make this (modified) accessory better suited to other applications; thus, in use, the modified accessory can be affixed e.g.
  • the door handle operating a cam which can project through through the (longitudinal) aperture to release the tongue tip(s), by engageing them or extensions thereof, to allow the door to be opened, whereby the fastening device of the present invention has an alternative application as a part of a lock.
  • the fastening device 10 shown in Figs.1,2,3 and 4 is formed from 0.4mm thick hard rolled stainless steel, in this embodiment from a rectangular blank of 80mm x 35mm ; it comprises a flat plate section 12 and two gripping members 14 and 16 which extend generally upwardly (as seen in Fig.2) from the plate section 12, and to the same side thereof. Between the gripping members there is retained an intermediate portion 19, in the same plane as the flat plate section 12, and which in an alternative embodiment has a nailing hole i.e. of smaller diameter than screw holes 18. As more fully described below, the gripping members 14,16 have their engagement tips 15,17 axially (i.e. upwardly as seen in Fig.1) and laterally offset.
  • the gripping member 14 is in the form of a tongue, provided by a substantially planar strip punched from flat plate section 12 and which is angled at 60 degrees to the plane of plate section 12, and in this embodiment reaches at its tip 15 a height of 10mm above the plane of plate section 12.
  • the second gripping member 16 is also in the form of a tongue, provided by a strip angled from plate section 12, to a height at its tip 17 of 9mm above the plane of plate section 12.
  • the gripping member 16 comprises two sections 16a and 16b.
  • the first section 16a is at 45 degrees to the plane of plate section 12, and the second section 16b, which is integral with the first section 16a, is at 85 degrees to the plate section 12.
  • fastening means such as a countersunk screw (or less preferably) a nail can be passed through each hole 18 to fix fastening device 10 to a surface, such as to surface 32 of a reveal 33 as seen in Fig.4.
  • a window unit 30 in this embodiment having a wooden frame 31, but in alternative embodiments having a frame of another known frame material such as UPVC or aluminium, is held in place in a structure (including in this embodiment reveal 33) which defines a window opening, by at least one fastening device 10 fixed by nails 35 through holes 18 to one surface 32 of the window opening.
  • the fastening device may have a (smaller) nailing hole in the intermediate section 19 for preliminary fixing, and then holes 18 are likely to be used for retaining screws.
  • fastening devices in accordance with the invention are fixed to each reveal around the window opening, and then the window unit 30 within frame 30 is offered up to the window opening and pushed into place up to and against plasterwork 34, with the gripping members 14 and 16 being deflected by the window frame 31. Any tendency for the window unit 30 to slide or be vacuum-drawn back out of the window opening either during fitting or subsequently is inhibited by the gripping members 14 and 16 which in this example both "'bite" into the window frame 31.
  • this stop is formed by one or more plates nailed to the reveal, each plate having an upstanding end part which when the plate is correctly positioned provides the inward abutment.
  • the device 40 in this embodiment is moulded from nylon, and comprises a flat plate section 42 and first and second gripping members 43 and 44.
  • the gripping members 43 and 44 have respective supports 43a and 44a, formed to minimise the deflection of the gripping members in use.
  • the plate is provided with holes 46 whereby, in use, the device may be fixed to a surface by fastening means e.g. a screw passed therethrough.
  • the device 40 is used in the same manner as that previously described for the device 10.
  • FIG. 7 shows a modified fastening device 50 fixed to a door frame 52 by screws 54.
  • Each of the laterally and axially spaced gripping members 56a,56b has a lateral extension (not seen in Fig.7 but respectively extending towards the other gripping member).
  • the door 60 is closed, and as seen in this view the plate 58 is fixed to the facing surface of door 60 i.e.
  • the gripping members 56 have at least their tips in engagement respectively in a pair of slots 57a, 57b one to either side of but not opening into aperture 59 in plate 58, and so acting to hold the door shut.
  • the handle 62 is manipulated by a user to rotate a cam 63 into and then through opening 59, the cam contacting the lateral extension(s) and deflecting the gripping members out of the slots 57a, 57b to allow the door to open about its hinge (not shown).
  • the slots 57a, 57b open into aperture 59; instead of lateral extensions to the respective gripping members, the gripping members for this embodiment are themselves made wider so that they encroach into aperture 59, from which they can be lifted by cam 63 to allow the door 60 to be opened.
  • the window frame 31 is of an extrudable material such as plastics (uPVC), as already commonly used for window frames.
  • the fastening device is formed integrally with the window opening, and such arrangement is advantageous in that it permits accommodation to variations in the receiving surface (for example the outwardly facing surface of the window frame), though in a further embodiment I prefer to form the fastening device integral with the frame to engage a depression in or recessed part of the surface defining the opening.
  • the arrangements can be used with a separate plate forming an inward abutment, limiting inward movement of the window frame.
  • fastening devices in accordance with the invention will fasten and hold a window unit in place in a window opening despite a loading of several tonnes on the window unit, such as may occur from the vacuum effect of a strong wind blowing substantially parallel to the glazing.
  • Fastening devices according to the invention if they are part of the window unit, allow a fully glazed window to be fitted in 5 minutes or less. With frame to masonry clearances due to thermally induced expansion/contraction of units rangeing from 1mm to 14mm on each side of the frame, the fastening devices did not release their locating and fastening loading.
  • Fastening devices in accordance with the invention are particularly advantageous in that, in use, they tend to centre the window in the window opening as the window is being fitted, and thereafter can hold the window securely in place without distorting the window frame. If non-continuous, usefully the fastening devices are positioned adjacent the corners of the window frame, or opposite transoms or mullions able to accept the (resilient) loading from the gripping members.
  • a fastening device in accordance with this invention as a latch is particularly advantageous in that the fastening device is simple and robust, and does not require high accuracy fitting.
  • This application also makes use of the unique features of the fastening device.
