Definitions

  • the present invention relates to a latching strip and a latching mechanism for windows or doors of the pivoting, swivelling or sliding type and especially those incorporating uPVC frame members and having latching/ locking components along one or more edges thereof.
  • windows or doors hereinafter referred to as sashes
  • Such windows or doors may be operated by an operating member either on the sash, or on a frame therefor, which activates, via a rack and pinion drive, one or more drive bolts provided with one or more latching members thereon to latch the sash in a closed position within its frame.
  • the latching mechanism of the present invention has been designed to achieve this and provide multi-point locking of the sash in its frame over an extended length or lengths of one or more side edges of the sash.
  • espagnolette multi-point locking systems include those which have a locking bar slidable in a groove in an edge face of the sash or frame with locking members attached to the locking bar and engageable with respective keeps in the other of the sash and frame in which the locking bar is not fitted. While these constructions operate perfectly satisfactorily, they are expensive to manufacture, since the locking members have to be attached to the locking bar at desired locations and a keep for each locking member has to be provided and fitted in the right place within the window or door for cooperation with its respective locking member.
  • the present invention seeks to overcome this disadvantage.
  • a latching strip for use in a latching mechanism for a door or window, the latching strip having a plurality of spaced hook-shaped members thereon which are integral therewith, adapted to cooperate with respective ones of a plurality of spaced keeps, the spacing of which corresponds substantially with the spacing of the hook shaped members.
  • the strip is connected either to a window or door sash or to the frame therefor and the keeps are mounted on whichever of the sash and frame on which the strip is not mounted.
  • the hook-shaped members on the strip are substantially equally spaced along at least a major part of the whole of the strip.
  • a latching mechanism comprising a latching strip as described above, and a plurality of keeps, one for each hook-shaped member .
  • the keeps are provided on a second strip of material and are in the form of apertures for receiving the hook-shaped members, the arrangement being such that the hook-shaped members can be inserted with a clearance fit into the keeps, but upon subsequently causing relative longitudinal movement between the strip carrying the integral hook-shaped members and the keeps, the hook-shaped members will be moved into latching engagement with the keeps.
  • the integral hook-shaped members are defined by apertures formed in the strip incorporating the hook-shaped members and these apertures have profiles corresponding substantially to the profiles of the apertures defining the keeps in the second strip of material.
  • the two strips of material are substantial mirror images of one another so that the keep apertures in the second strip define hook-shaped members integral with the second strip and the first mentioned strip with its integral hook-shaped members has apertures therein with which the hook-shaped members, integral with the second strip can engage.
  • both the first mentioned strip and the second strip are of generally U-shaped cross-section and the hook- shaped members and apertures in each strip are provided on the strip in the vicinity of a junction between the base of the U-shape and one of the upstanding arms of the U, the apertures in each strip thus allowing the hook-shaped members of the respective strips to interdigitate with each other, whereupon relative movement of one strip with respect to the other will cause the hook-shaped members to move into latching engagement with each other.
  • the first mentioned strip is preferably mounted for sliding movement on the sash, preferably so as to be slidable to and fro along a channel extending lengthwise in an edge face of the sash under the control of a sash operating member and the second strip is fixedly mounted on a frame member for the sash.
  • two first strips may be provided, one to either side of an operating member on the sash, which cooperate with either a single second strip or two second strips of substantially the same length as the two first mentioned strips.
  • Figure 1 is a transverse section through part of a window sash located in a closed position in a frame therefor and showing a first locking strip mounted on the sash and a second keep strip mounted on the frame for cooperation with the locking strip,
  • Figure 2 is a side elevation showing the keep strip and locking strip of Figure 1 spaced apart in a position which they would occupy shortly before the window in is its closed position shown in Figure 1,
  • Figure 3 is a view similar to Figure 2, but showing the two strips in a closed position corresponding to that of Figure 1,
  • Figure 4 is a view similar to Figure 3, but showing the two strips after one has been moved relative to the other to move the strips into a latched or locked position, and
  • Figure 5 is a section on the line V-V in Figure 3.
  • Figure 1 shows a frame member of a window sash formed of uPVC material, reinforced by a metal reinforcement M and having in an outer edge face thereof, a longitudinally extending groove G.
  • the window sash locates in a uPVC frame, part of which is shown at F, and the frame F is also reinforced with a metal reinforcement strip M 1 .
  • the two uPVC frame sections S and F are generally of known construction.
  • a first U-shaped strip of material 1 is slidably supported on the edge face of the frame member F under the control of a drive rod 3 located within the groove G, the drive rod 3 being reciprocated in a known manner e.g. by means of an operating handle for the sash which operates a rack and pinion drive mechanism in known manner.
  • the first strip 1 comprises a locking strip of U-shaped cross-section of a width such that it closes off the groove G with the open face of the U facing into the groove.
  • the U-shaped locking strip 1 is secured to the drive rod 3 in an appropriate manner.
  • a second strip 5 Fixedly secured to the frame F and extending longitudinally along an edge face thereof which is arranged opposite the edge face of the frame member S when the sash is closed is a second strip 5 of generally U-shaped cross-section, the precise nature of the U-shaped cross-section being selected so that the strip 5 can be firmly secured to the edge face of the frame F by at least two screws 7 extending through apertures 10 provided at least in the two ends of the second strip 5, which forms a keep strip.
  • the first locking strip 1 has a plurality of spaced hook- shaped members 9 thereon which are formed in the material of the U-shaped strip as a result of apertures 11 being formed in the strip 1.
  • the hook- shaped members 9 are equally spaced from each other, as are the apertures 11 and the apertures 11 extend into the U- shaped strip across a corner defined by a first arm 13 of the strip and the base 15 of the strip, the aperture being generally rectangular in the first arm 13 and in the base 15, generally rectangular, but with a longitudinally extending extension portion 17 in the base 15.
  • the extension portions 17 thus give each hook-shaped member 9 their hook shape, the hook shape being formed in the base 15 of the U-shaped strip.
  • the second U-shaped strip 5 has arms 19 and 21, and apart from the precise length of the arms 19 and 21, which in use, is secured to the frame F, the second strip 5 is a mirror image of the first strip 1 and is thus also provided with hook-shaped members 23 defined by apertures 25 formed therein.
  • the apertures 11 in the first strip or keep strip 1 have a width at their mouth which is fractionally greater than the width (measured along the length of the strip) of the hook-shaped members 23 formed in the second strip 5.
  • the width of each aperture 25 formed in the second or locking strip 5 is fractionally greater than the width of the hook-shaped members 9 on the first or keep strip 1.
  • the hook-shaped members in each strip 1,5 are defined by apertures in the respective strips, the hook- shaped members are integral parts of their respective strips.
  • first locking strip 1 may be moved towards the second keep strip 5 in a direction at right-angles to the longitudinal axis of the two strips, which will result in the hook-shaped members of 1 strip fitting snugly within the apertures of the other strip, i.e. the strips will be moved into the relative positions shown in Figure 3 and in Figure 1, with one corner of the first strip 1 having its hook-shaped members 9 interdigitating with the hook-shaped members 23 on one corner of the second strip 5.
  • This position represents a closed position of the two strips which will then allow the two strips to be moved into locking engagement with each other by moving the first strip 1 under the control of the drive rod 3 , longitudinally relative to the second strip 5 to the position shown in Figure 4.
  • the present invention provides a plurality of spaced hook-shaped members on the first strip 1 which can be moved into latching engagement with the apertures 25 in the second strip 5 and by providing the second strip 5 as a mirror image of the first strip, hook-shaped members on the second strip can likewise be moved into latching engagement with the apertures 11 in the first strip which define the hook- shaped members 9 therein. If the strips 1 and 5 are provided along the whole length of an edge face of the sash S and frame F, therefore, respectively, multi-point latching along the whole edge face of the sash S is provided. It may be, however, that because of the operating mechanism for the sash S, this is not possible and it may be necessary to provide two separate strips 1, one to either side of the operating mechanism for the sash S.
  • the strips 1 and 5 may be formed of any material sufficiently strong to withstand forces applied to the window sash S which occur when attempts are made to force open the window. While metal strips will be perfectly satisfactory, it is preferred that a material which does not rust is used for each strip.
  • the first strip 1 need not be U-shaped but must merely have hook-shaped members thereon which are engageable with appropriately spaced keeps, and that these are preferably provided by apertures in the second strip 5, so that the first strip 1 can then be caused to engage with the second strip 5 once the two strips 1 and 5 have been moved longitudinally relative to one another. It is, however, preferred that two identical U-shaped strips are provided since these provide maximum flexibility for fitting to the window sash S and frame F therefor respectively and also provide maximum strength and durability.
