Definitions

  • This invention relates to a mounting system for a closure member in an assembly and improvements thereof which allows the secure sliding and subsequent pivoting of the closure member from a position parallel to the assembly, wherein sliding of the closure member is allowed to a fully pivoted position.
  • the invention is preferably embodied in a window assembly but finds application also in large pivoting windows and patio doors.
  • Double hung windows are well known in the art. There are a multiplicity of examples of such double hung windows which incorporate window frames for the sliding of a window sash within a jamb guide. Further there are many examples within the prior art which allow for the sliding of a window sash within a frame within the jamb channels thereof which further incorporate a carrier or shoe attached to the window sash which allows for the pivoting of the window sash away from the window frame.
  • a multiplicity of designs for sliding patio doors further exist within the prior art.

  • a cover portion may be provided over the track portion 15 of sill portion 220 and header portion 220 of Figure 18 that engages with the sash profile in a similar way to that of the track cover of Figure 15a with the exception that the track cover only extends over the second half of the track, that is to say the second half not carrying the window .
  • the wheel portion 39a may be eliminated and the track cover may extend along the track portion opposite the pivot assembly so that the sash may slide on the track cover and be assisted to be supported by that track cover only in the second half of the track profile thereby eliminating the second carrier of Figure 2.
  • the track cover therefore in Figure 2 as an example would extend from the carrier 39a toward the left side of the page to allow the pivot assembly 35 to move to approximately the position of the present carrier 39a wherein it would engage the track cover. In the movement of the carrier 35 to that position, the other end of the window would already be supported by the track cover. This installation therefore would eliminate the carrier 39a.

  • a second pinion 267 which is rotated effectively by the movement of the rack portion 266. Rotation of the pinion 267 causes rotation of the pinion sector 268 which is engaged with the locking detent 269 for the latch plate 270 and the detent 271 thereof.
  • This latch plate is typical for casement windows as is the movement of the lock 269, i.e. the rotation thereof.
  • the central locking system provided with this invention, it is the one handle operation of both the detents 250 and 251 and the casement window lock 269 which is in combination the essence of the central locking system.
  • the casement window portion may be left out and the essence of the locking system therefore includes the locking block in the track which provides a detent for the locks 250 and 251 respectively.
  • the sashes 220 are provided with an opening 227 wherein a corner connector 280 is provided which extends into the opening 227 proximate all four corners and eliminates the necessity for welding.
  • Clip portions 281 bite into the vinyl and are tapered in a direction so as to prevent the removal of the corner connectors once inserted within opening 227.
  • This snap lock feature therefore provides for the installation of the corner connectors and the quick fastening of the sash profile around the glass G.
  • the track covers 230 are therefore provided and snapped into position once the closed cell foam, best seen in Figure 15a at 240, is inserted within the opening of the sash profile.
  • the hardware therefore including the top and bottom track engaging portion 39x and 37x, the shaft 32, the connector 31bx, the other shaft 31 , and the small shaft 34c are provided proximate the pivoting end of the window assembly within the sash profile enclosed by a cover similar to that of cover CX.
  • the central lock as described in relation to Figures 16, 16A and 16B is therefore inserted within the other opening of the sash profile and assembled and covered by the cover CX.
  • the window sash is now available for installation within the frame assembly of Figure 18 once the carrier portions 39x are engaged with the respective shafts 32 and 34c.
  • the block portions 200 are therefore locked in position once the track is installed in the frame, and the nut portions are adjusted to allow for the parallelism of the carriers 39x within the tracks to ensure the parallelism of the sash so that it rides well within the track portions.
  • the window is therefore assembled.
  • a casement window occupies a certain standard space in the industry, and because of the linkage systems and the known systems, it is not possible to provide a larger window.
  • a larger casement window may be provided which is easily installed with the minimum amount of labour and assembly time required. Should the window now be mis-aligned for any reason, it may be easily adjusted by the rotation of the screw 206 provided. A sophisticated user therefore could easily adjust this once instructed over the phone by an installer, or alternatively the installer may return for a quick adjustment at any time. Also, the window assembly is less likely to go out of adjustment because of the great care taken in the development of the precision of the assembly.
  • a method therefore of assembling the window may be considered as described in the above-mentioned description wherein, firstly the sash components are assembled by the quick fastening feature of the corner locking portions which are inserted within the opening of the sash profiles provided and provide one ⁇ way friction fit.
  • the closed cell caulking is therefore inserted within the top and bottom of the sash assembled and these portions are covered by the track covers by the compression of the closed cell foam and the engagement of the tabs of the track cover with the tabs of the sash profile.
  • the hardware is then installed along the vertical portions of the sash within the openings thereof opposite the glass which is then covered by a sash cover portion provided.
  • the hardware located proximate the pivoting end is therefore installed on the carrier portions and inserted within the track portion within the sill and header, for example of a window assembly.
  • the window is therefore closed in position with the sash covers or track covers located proximate the sill and header snapping into the frame and closing any path for air to enter the window and pass the primary seals provided as best seen in relation to the Figure 15 A.
  • the track covers also provide blockage of light, air and the friction fit of the sash into the track portions. By providing a track cover along the track remote the pivoting end of the window, this track cover may be used as support as well for the window assembly.
