  • Such apparatus conventionally comprises a link arrangement having a first link which mounts the window and which is pivotally mounted on a track having a clos ⁇ ure member at one end.
  • the closure member is engaged by the respective end of the first link when the arrange ⁇ ment is moved to the closed position, the engagement correctly aligning the link arrangement with the track and retaining the correct alignment in the closed position.
  • the link arrangement For security and other purposes it can be desir ⁇ able for the link arrangement to automatically limit the extent of opening of the window.
  • the apparatus for supporting a component for movement between an open and a closed position in a fixture opening, the apparatus comprising a link arrangement having a first member for mounting the component and a second member for pivotally mounting the first member on a third member, the latter being adapted to be secured to the fixture opening, the third member comprising a track, and a fourth member for pivotally mounting the first member on means which is slidably located in the track, latching means being provided, whereby, when the link arrangement is moved to a first open position, further opening movement is prevented, the latching means being releasable to selectively enable further opening movement, and subsequent reinstatement of the latching engagement.
  • the slidable means provides the latch ⁇ ing means in the form of a latching component which is biassed outwardly of the track, and the track provides means engageable by the latching component, the latter being adapted to release the latching engagement when pressure is applied thereto against the biassing force.
  • the track is generally of U-shape with the legs being inwardly turned at their free ends to form retaining walls, the latter being profiled at at least one location intermediate the length of the track, whereby the latching component, on reaching the profiled location, is biassed outwardly through the walls to prevent further movement of the slidable means in the track in the direction for opening of the window.
  • the latching component may locate in the track with shoulders on respective sides of a central section below the inwardly turned walls thereof. Further, end parts of the shoulders of the latching component may be profiled to have faces which are located adjacent the track walls angled in a direction towards the central section for controlled movement of said end parts through the walls of the track at the profiled location. Said faces of the shoulders preferably merge laterally outwardly and in a direction away from the central section with respective lateral outer edges of the shoulders, and free end edges of the end parts of the shoulders are preferably angled towards the other end of the latching component to facilitate latching engagement with respective edges of the walls of the track at the profiled location.
  • the latching component may be mounted on the slidable means by an arrangement provided to transmit loading on the latching component to the sliding means and away from the mounting therebetween, and the latch ⁇ ing component may have a slotted hole through which the mounting can locate, the slotted hole providing for relative movement at the time of mounting, thereby to engage respective end edges of the shoulders against the slidable means for said transmission of loading.
  • the respective end edges of the shoulders may be angled in a direction away from the central section to enable engagement with the slidable means over an increased length of edge.

  • the support member 16 is pivotally mounted on one end of a link 20, the other end of the latter being pivotally mounted on a slider 22 which is slidably located in the track 10.
  • the slider 22 also pivotally mounts one end of a further link 24, the other end of the link 24 being pivotally mounted on the pivot member 18.
  • the latter is stepped along its length to provide a raised section 26 on which the link 24 is mounted, so as to provide clear ⁇ ance for the link 24 in the closed position.
  • a further link 28 is pivotally connected between the member 16 and the link 24.
  • the track 10 is closed by a member 30.
  • the latter is mounted on the track 10 by any suitable means and overlies the track end, being of the same width as the track 10.
  • the slider 22 (Fig. 5), for example formed of a plastics material, has an elongate body having a central upstanding section 32 presenting respective side shoulders 34, 36 which lie in the track 10 below the respective walls 12. Through the section 32 there are formed two longitudinally spaced holes 38, 40 for mounting of the respective links 20, 24, for example by way of rivets. A further internally threaded hole 42 is formed in the section 32 to receive a conventional friction screw (not shown). The section 32 has a reduced height area 44 towards the end remote from the threaded hole 42, the area 44 terminating at an arcuate edge 46. The hole 40 is located within this area 44.
  • the slider 22 also mounts one end of an elongate strip 48 (Figs. 2 to 4), the strip being preferably formed of a one-piece component of temper stainless steel.
  • the strip 48 has a main body part 50 defined by a central elongate section 52 upstanding from respective side shoulders 54, 56, the latter lying in the track 10 below the respective walls 12.
  • the strip 48 has end parts 57 of the respective shoulders 54, 56 profiled for a purpose hereinafter described, the profiled end parts 57 terminating short of a rounded end 59 of the upstanding section 52, with upper faces of the shoulders 54, 56 being upwardly angled, relative to the section 52, in a direction towards their free ends, but merging outwardly and downwardly with respective lateral edges 58, 60 of the shoulders 54, 56.
  • Respective end edges 62, 64 of the latter are angled rearwardly of the section 52 relative to the end 59 thereof, and the central section 52 gently sweeps upwardly, i.e. in a direction away from the shoulders 54, 56 towards the end 59, the edges 62, 64 extending below the shoulders 54, 56 to provide an increased edge length for latching purposes, as hereinafter described.
  • an integral mounting finger 66 having an arcuate outer end edge 68.
  • the finger 66 is provided with a slotted hole 70 and is formed to extend upwardly from the plane of the central section 52. End parts 72, 74 of the shoulders 54, 56 adjacent the finger 66 are turned downwardly relative to the central section 52 for a purposes hereinafter described.
  • the strip 48 is mounted on the slider 22 by the finger 66 locating on the slider area 44 with the slotted hole 70 overlying the slider hole 40.
  • the end edge 68 of the finger 66 has the same curvature as the edge 46 on the slider 22.
  • the end parts 72, 74 of the shoulders 54, 56 of the strip 48 engage the respective end edge 76 of the slider 22.
  • the hole 70, being slotted facilitates slight longitudinal movement of the strip 48 relative to the slider 22 when being secured thereto, whereby the end parts 72, 74 are compressed against the slider end edge 76 over a relatively large surface, to avoid loading on the strip 48 being transmitted to the mounting, for example the rivet.
  • the respective walls 12 are profiled at aligned locations by way of cut outs 78.
  • the spring strip 48 is biassed outwardly of the track 10, so that when the free end of the strip 48 locates below the cut outs 78, the strip end parts 57 move upwardly through the cut outs 78 until the end edges 62, 64 partly extending above the walls 12, move into latching engagement therewith. This prevents further movement of the strip 48 along the track 10 in the direction away from the end closure 30, until manual pressure is applied to the strip by way of the end 59 to move the strip back into the track 10 with the strip end below the level of the walls 12, whereupon further movement of the strip 32 is possible.
  • the cross-section of the strip 48 provides both longitudinal stiffness and also clearance above the fixing devices which engage through the apertures 14 in the base of the track 10 to mount the latter on the respective part of the window frame.
  • the profile of the end parts 57 of the shoulders 54, 56, together with the angled end edges 62, 64 provides a sufficient length of edge for positive latching engagement, ensuring that such engagement cannot be removed without manual pressure being applied to the strip.
  • the profile enables the required positive location in one direction only, and the length of the end edges 62, 64 is important in ensuring that the strip 48 remains clear of the fixing devices when manual pressure is applied.
  • the profile, as well as the provision of the elongate shoulders, provides maximum stiffness in the strip 48.
  • the slightly raised end 59 of the central section 52 provides an easy finger rest for an operator to apply the required manual pressure.
  • the latter may be upwardly indented adjacent the cut-outs 78, at those ends not engaged by the end edges 62, 64 of the strip 48.
  • the use of such indents aids the stiffness of the track 10.
  • the support member 16 may be swung from the position shown in Fig. 1 to a closed position where ⁇ in the support member 16 overlies the pivot member 18 and the links 20, 24, the latter in turn overlying the track 10. It will be appreciated that in the closed position the window supported by the link arrangement is also closed.
  • the side walls 12 of the track 10 may be indented upwardly at locations other than adjoining the cut-outs 78. This can be of advantage in friction stays which are intended to be hung on vertical side members of a window frame, as these additional indents would raise the link 24, preventing fouling of the latch.
  • the angular extent of opening of the window is initially limited by movement of the end of the strip 48 to the location of the cut outs 78 in the walls 12.
  • the angling of the end edges 62, 64 enables smooth movement of the free end upwardly through the cut outs 78 until there is latching engagement between the end edges 62, 64 and the edges of the cut outs 38. Further opening is achieved by the user pressing on the strip end 59 to move the latter back into the track 10, and thereafter the angular extent of further opening is limited by a stop 80 formed in the base of the track 10 being engaged by the slider 22.
  • the window can be retained in any desired angular position, principally due to friction engagement between the slider 22 and the track 10.
  • Movement from an open position to the closed position is guided in a known way by engagement between a respective end of the elongate member 16 and a cam surface of the. closure member 30. It is to be appreci ⁇ ated that the link arrangement can move to the other side of the track 10. Movement from the open position on that other side to the closed position is guided again by the respective end of the closure member 16 and a further cam surface of the closure member 30. Therefore the component is double-handed.
  • the free end configuration of the elongate strip 48 has the end parts 57 of the respective side shoulders 54,56 angled relative to the central section 52. Also the end edges 62,64 are angled downwardly and rearwardly from the section 52.
  • the strip 48 functions as described herein before.

Abstract

Dans un support de fenêtre à friction, un élément coulissant (22) monté dans une glissière (10) est fixé à une extrémité d'une barrette d'accrochage (48) qui est également située dans la glissière (10), les côtés étant disposés sous les parois de retenue (12) de la glissière (10). La barrette (48) est maintenue appuyée vers l'extérieur de la glissière, et à l'une de ses extrémités possède des épaulements profilés. Les parois (12) ont des découpes (78) et lorsque l'extrémité de la barrette (48) munie des épaulements profilés se trouve au-dessous des découpes (78), l'extrémité de la barrette (48) monte à travers les découpes (78) pour s'enclencher dans les parois (12). Cela limite la distance d'ouverture angulaire de la fenêtre. Une ouverture encore plus grande de la fenêtre peut être obtenue par l'utilisateur en appuyant sur la barrette afin de ramener celle-ci dans la glissière (10).
