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.
• 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, for example to fit into an opening from which a single glazed unit is to be removed so that a replacement double-glazed window or triple-glazed window can be fitted.
• a 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 comprises a plate fixable to the surface
• a gripping member associated with the plate and resiliently biased away from the plate whereby, in use, the gripping member is deflected by the article and frictionally engages the article to inhibit sliding movement in a particular direction of the article relative to the surface.
• a fastening device for securing two members against relative movement in one selected direction which includes a first part fixable to one of the members and a second part engageable with the other of the members, the second part being spaced from the first part and being resiliently deflectable towards the first part to permit relative movement between the members in a direction opposed to said one selected direction, the second part being coupled to the first part such that movement of the other of the members in said selected direction can be resisted by the said one of the members with the second part concurrently being urged further away from said first part.
• the first part is a flat plate and the second part is a tongue tip, the tongue being formed integrally with the plate and angled thereto, the plate and tongue being of austenitic stainless steel compressed and hard rolled to British Standard 5770 and with a high tensile strength of above 50 tonne per sq. in and usually about 85 tonne per sq. inch.
• 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 to the plate, and a second tongue extending at a greater angle and to the same side of the plate, 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 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 the masonry 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.
• the first and second tongues are separated laterally by an intermediate portion of the plate, 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 still engage the unit, or can engage the opening structure if the fastening device is mounted on the unit.
• the first and second tongues are axially spaced one from the other so that at least one can engage the frame (or opening structure).
• fastening devices as herein disclosed can be affixed to the structure forming the opening, prior to the insertion of a pre-assembled (ready-glazed) window unit, this may not always be the preferred arrangement, since the fastening devices have to be secured e.g. in a window opening, individually on site.
• the fastening devices are pre-fitted to the window frame, or preformed as part of the window frame - as when this is a plastics extrusion; and for this alternative arrangement with the gripping devices carried by the window unit, then the tongue tips can locate and 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 one or both of the tongue tips, 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.

• Fig.10 is a perspective view of a modified fastening device, with as background a structure opening.
• 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 80mn ⁇ 35mm ; it comprises a flat plate section 12 and two gripping members 14 and 15 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
• 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 13 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.
• the fastening devices are secured to the window frame, and so the gripping members 14 and 16 are deflected towards the window frame 31 as the window unit is pushed into place up to and against an internal stop which again can be plasterwork 34, with the tip of one or both tongues engaging the structure defining the opening.
• the fastening device is a stainless spring-steel member with angled serrated tongues, as seen in Fig.10, and which is fixed to the frame itself during frame manufacture, rather than on-site.
• gripping member 116 extends slightly further away from the plane of plate 12 than does gripping member 114.
• the tip 20 of gripping member 115 is serrated; gripping member 114 also has a tip 22 which is serrated, but with less sharp serrations than tip 20.
• 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.
• 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.
• 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.
• 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.
• the plate and gripping member may be separate i.e. non-integral members, coupled together but biased apart by a separate resilient member such as a plate or leaf spring.
• the fastening devices above have been generally described by embodiments wherein they are fixed to the the surface of a reveal, when the device is fixed to, or integral with the window unit, the arrangement is advantageous in that it permits accommodation to variations in the surface (for example of the brickwork forming a reveal, generally as seen in the background to Fig.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 53 to allow the door 60 to be opened.
• the use of 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 feature of the fastening device of being a spring loaded self-tensioning fixing.
