Definitions

  • the present invention relates to a stay suitable for supporting a window in a frame in such a way that the window can be opened by moving it pivotally out of the plane of the frame on the stay.
  • This stay includes a track which in use is fixed to the window frame.
  • a slider is mounted in the track and the different struts and braces making up the stay are pivotally connected to each other and to the slider or to different points on the track.
  • the struts and braces are arranged so that when the stay is closed they overlie the track and as the window is opened they pivot outwards to support the window at an angle to the frame.
  • the patent cited above proposes a stop formed as a plastics plug which is fitted to a strut pivotally connected to the track and by interference with the track prevents the stay being opened beyond a certain angular position.
  • a stop however only offers a limited amount of resistance to further movement of the stay and is difficult to release. Normally, the stop having once being fitted, it is only practical to remove it occasionally as when, for example, it is necessary to open the window fully to clean it.
  • the stay in a stay including a track, a slider which in use moves along the track, and stay members pivotally mounted to the slider, the stay further comprises releasable means acting between the slider and the track which, when engaged, prevent the slider moving beyond a predetermined position thereby preventing the stay opening beyond a corresponding predetermined angular position and which are releasable for movement of the stay beyond that position.
  • the present inventors have found that by providing a releasable means such as a catch or stop which acts between the slider and the track it is possible to prevent movement of the stay beyond a fixed angular position whilst still allowing unimpeded operation of the stay over its full angular range once the catch is released. It is found that a catch or stop acting between the slider and the track offers improved resistance to opening of the stay. Simply by selecting an appropriate position along the length of the track for the catch or stop, it can be made effective at any desired angle and is not limited to use at a small angular displacement. At the same time the catch or stop formed in this manner adds only minimally to the cost and complexity of the process of manufacture of the stay.
  • the catch or stop may be formed integrally with the slider, or alternatively may be formed separately, with the slider engaging or abutting the catch or stop as it reaches the predetermined position.
  • the releasable means acting between the slider and the track include co-operating self-setting first catch means which interengage to hold the stay at the predetermined angular position.
  • catch is self-setting, since this greatly facilitates use.
  • the stay further comprises second catch means which inter-engage in a region spaced from the co- operating first catch means, and in combination with the first catch means hold the stay at the said predetermined angular position.
  • the self-setting first catch means comprise a resiliently biased member mounted on the slider and a complementary formation at a predetermined position along the length of the track, as the stay is opened the slider and the resiliently biased member moving along the track until the resiliently biased member reaches the complementary formation where the resiliently biased member engages the complementary formation thereby holding the slider against further movement.
  • the resiliently biased member and the complementary formation are arranged so that as the stay is closed the resiliently biased member moves freely past the complementary formation without being held.
  • the track is of channel section and the complementary formation is formed in a side wall of the track.
  • the complementary formation is a slot formed in the side wall and the resiliently biased member includes a projection arranged to engage the slot.
  • the resiliently biased catch member includes a release member extending away from the side wall of the track which is operable to move the resiliently biased member out of engagement with the complementary formation.
  • Figure l is a plan of a first example of a stay
  • Figure 2 is a partially sectioned plan view of part of the stay in the region of the catch;
  • Figure 3 is a cross-section;
  • Figure 4 is a side elevation of the track of the stay of Figure 1 in the region of the catch;
  • Figure 5 is a plan of a second example of a stay
  • Figure 6 is a plan view of a detail of Figure 5;
  • Figure 7 is a part section view showing the stay of Figure 6 with the catch engaged;
  • Figure 8 is a side view; and Figure 9 is a sectional end view.
  • a friction stay includes a track 1 a slider 2 mounted in the track 1 and pivotally connected stay members 3,4,5,6.
  • the stay members are arranged in a conventional manner with forward links 4,5 pivotally mounted on the slider 2, a rear link 6 pivotally connected to a fixed point towards one end of the track 1, and a main bar 3 pivotally connected to the ends of the forward and rear links 4,5,6 at the ends away from the track 1.
  • the stay is arranged so that in a closed position the main bar 3 overlies the track 1 and as the stay is opened the slider 2 moves along the track 1 so that the stay members 4,5,6 are configured to support the main bar 3 at an angle to the track 1.
  • the stay includes a self-setting catch 7, which as the stay is opened engages to restrict further opening of the stay beyond a partially opened configuration, as shown in Figure 1.
  • the catch 7 is shown in greater detail in Figure 2.
  • a catch member 8 in the form of a thin elongate bar is pivotally mounted to the slider 2 (omitted from Figure 2) towards the forward end of the slider, that is the end which leads as the stay is opened. Part of the catch member 8 extends beyond the forward edge of the slider 2.
  • the track 1 is of channel-section and the slider 2 includes a depending inner wall 9 which is substantially parallel to the side walls of the track 1.
  • a spring 15 is fixed between the inner depending wall of the slider 2 and the catch member 8 and operates to bias the catch member 8 into engagement with one side wall 10 of the track 1.
  • the slider 2 moves along the track with the catch member 8 in sliding engagement with the side wall 10.
  • the catch member 8 then engages a format ;n 11 at a predetermined position in the side wall 10 of the track 1 to hold the stay against further opening until the catch 7 is released.
  • the formation 11 engaged by the catch member 8 comprises a cut and indented portion immediately adjacent the cut in the side wall 10 of the track l.
  • the indentation provides a surface 12 extending into the channel 1 away from the side wall 10. This surface 12 abuts the forward edge of the catch member 8 holding the catch member, the slider, and hence the whole stay against further opening.
  • the catch member 8 includes at its forward end a folded-over portion which overlies and extends beyond the side wall 10 to provide a release member 13.
  • the release member 13 moves the catch member 8 away from the side wall 10 against the force of the biasing spring and out of engagement with the formation 11.
  • the slider 2 is then free for further movement down the track enabling the window to be opened further.
  • the indentation includes a camming surface 14 so that as the stay is moved back from the opened position towards its closed position the catch member 8 rides over the camming surface 14.
  • the biasing spring moves the catch member back into engagement with the side wall 10 thereby setting the catch so that the catch member 8 again engages the formation 11 when the stay is next opened.
  • catch engages on the side wall of the track other arrangements are possible in which, for example, a resilient catch member might be provided on the slider to engage an aperture in the bottom of the track 1.
  • Figures 5 to 9 show an alternative embodiment.
  • the formation 11' engaged by the catch 7' is a slot formed in the side wall 10' of the track l 1 .
  • the catch 8 1 includes a projection 21 which is biassed into engagement with the side wall 10. When the slot is reached the projection 21 moves into the slot and the forward edge 12' abuts the edge 16 of the slot to hold the slider against further opening.
  • the trailing side of the projection 21 is provided with a sloped camming surface 14* so that as the stay is closed the catch rides over the formation 11* without engaging.
  • One end of the catch member 8* includes a generally flat portion 19 which overlies the end of the slider 2'.
  • the resilient biasing for the catch member 8' is provided by a spring 15' located in the slider 2' .
  • the spring 15' bears on a depending tab 20, formed integrally with the catch member 8' .
  • the catch member 8• is formed from a single piece of sheet metal and, away from the generally flat portion 19, has a downwardly curved cross-section, as shown in the end view.
  • the catch includes a release member 13' .
  • the release member is formed away from the projection, at the far end of the catch member 8* and overlies the side wall 17 opposite the side wall including the formation 11'.
  • the release member includes an upturned portion which the user takes hold of to pull the catch out of engagement with the slot.
  • the stay includes two catch positions, one for the partially open position and a second for the fully open position.
  • the second catch is provided by another slot 18 further along the side wall 10* of the track 1'. This is engaged by the projection 15' in just the same way as described above for the first slot.
  • the partially open position is provided with a secondary catch mechanism which prevents accidental release of the catch.
  • This secondary catch includes a projection 22 which is formed integrally with the release member 13' .
  • the projection is formed by cutting and pressing a central portion of the release member 13' so that the projection extends inwards towards the track at a level below the top of the track.
  • a corresponding slot 23 is formed in the side wall 17. In the closed position the projection 22 extends into this slot 23 and clears the edges of the slot.
  • a secondary catch mechanism is also provided for the second, fully open, catch position.
  • a second slot 25 is cut into the side wall 17 in a region corresponding to the position of the release member 13• when the stay is in the fully open position. Engagement between the projection 22 on the release member 13' and the slot 25 serves to hold the catch against accidental release in the fully open position, and engagement between the rear edge 26 of the projection and the opposing edge of the slot 25 serves to prevent the stay being pushed shut as a result, for example, of wind blowing against a window mounted on the stay.

Abstract

Un montant se compose d'une glissière (1) et d'un bloc à coulisse (2) monté dans la glissière (1). Des éléments de montant (3, 4, 5, 6) reliés de manière pivotante, sont montés sur le montant et le bloc à coulisse. La glissière (1) et le bloc à coulisse (2) sont pourvus d'un premier système associé d'accrochage (7) à réglage automatique qui se met mutuellement en prise pour maintenir le montant dans une position angulaire prédéterminée et qui se libère facilement pour permettre le déplacement du montant au-delà de cette position. Dans un autre exemple, un deuxième système d'accrochage (22, 23) est prévu pour fonctionner en association avec un premier système d'accrochaghe (7') afin de maintenir le montant dans une position angulaire prédéterminée et, également, afin d'empêcher la libération du système d'accrochage avant le retour en arrière du bloc à coulisse depuis la position angulaire prédéterminée.
