  • tools apparatus or equipment hereinafter “tool” or “tools”
  • the blinds and apparatus of the invention with which the tools of the invention are of particular use are applicable primarily to apertures glazed with a transparent, translucent, coloured or colourless glass pane or panel, but may also be used with other suitable glazing materials such as transparent, translucent, coloured or colourless plastic sheets.
  • glazed window refers primarily to external windows of buildings, such as houses and offices and also includes conservatories. Further, unless the context requires otherwise, "glazed window” as used herein encompasses other glazed apertures such as glazed doors, glazed internal partitions (such as in offices) and other like locations
  • a roller blind comprises a web of fabric which in the shading configuration lies approximately parallel to the window and in the exposing condition is wound around a rigid roller or the like conventionally arranged near the top of the window.
  • Vertical blinds include a plurality of panels or slats which hang vertically from a head rail conventionally mounted near the top of the window. Mechanisms are provided, primarily in the head rail, by which the panels can be rotated about their longitudinal axes and by which the panels can be moved along the head rail laterally with respect to the window, by both of which means the degree of shading of the window is adjusted.
  • Venetian blinds which are also known as slatted blinds, are also well known and conventionally comprise an upper supporting structure in the form of a head rail from which depend two or more spaced apart ladders.
  • the ladders comprise a pair of longitudinal cords or threads aligned in use substantially parallel to the window with a plurality of lateral threads inter-connecting the longitudinal cords at regular intervals.
  • the lateral threads support respective laths or slats which form the shading part of the blind.
  • the slats may rest on the lateral threads without any attachment, or some or all of the slats may be directly connected to respective lateral threads.
  • Mechanisms are conventionally provided by which the blind can be raised and lowered so that it can adopt configurations in which the window is wholly shaded, partially shaded or unshaded.
  • Such mechanisms will normally include at least one lift cord which may pass through holes defined in the slats of the blind or may, for example, run behind the slats.
  • mechanisms are provided by which the slats can be tilted or inclined out of a nominally horizontal alignment into alignments tending towards the vertical, thereby to vary the degree of shading provided by the blind. Tilting is conventionally effected by adjusting the configurations of the longitudinal cords of the ladders.
  • Pleated blinds are also well known and comprise a supporting structure in the form of a master rail.
  • the master rail is often located in use at an upper portion of the glazed aperture, but this is not necessarily so.

  • the surface 46a of the base portion 46 is proud of the under-surface 36' of the fingers 36 (that is, depth "d" is greater than the depth of walls 52) which ensures that the glass pane 20a is contacted by the base portion 46 (which is preferably made of a plastics or other polymeric material) in preference to the (metal) bracket 28, 30.
  • This construction is advantageous in that forces due to the inherent weight of the blind and also operation forces of the blind (which principally occur when raising or lowering the blind) are not primarily transferred via to the metal brackets and thence to the glass. Rather, such forces are transferred through the base portion 46. As noted above, in the prior art transfer of such forces through metal brackets potentially transfers stresses to the glass very locally through the edges of the metal brackets.

  • the channel of the socket 66 includes an outer wider portion sized to accommodate the head of the screw and an inner, narrower, portion sized to conform with the thread portion of the screw.
  • the post portion may include a captive nut which is free to slide along the length of at least part of the post portion 48 and which receives a corresponding bolt via a channel in the socket 66.
  • the arrangement described in WO2008/015440 is not confined to a post and socket arrangement where a post portion 48 of a mounting formation 38, 40 is inserted into a socket 66 of a connecting component 62, 64.
  • the post portion 48 may be formed with one or more walls which define an internal hollow void which acts as a socket, the internal shape and dimensions of which are sized to conform with the external shape and dimensions of a projecting member (plug) formed on the connecting component 62, 64, so that the plug is slidably received in the socket.
  • a significant advantage of the post portion 48 and socket 66 arrangement is that the connecting components 62, 64, and hence the head rail 24 are almost infinitely adjustable with respect to the length of the post.

This ensures that no unintended gap is left between the head rail 24 and the frame 10.
  • the mounting formations 38, 40 are configured so that the post portion 48 is inclined slightly upwardly, typically by not more than about 10°, preferably not more than about 5° and more preferably not more than about 2° to 3° (with respect to a line perpendicular to the plane of the glass pane 20a).
  • This feature is advantageous in preventing the blind, when mounted, from tilting forwards away from the window.
  • the base portion is provided with a formation or lip 46b which bears against the web 32 and ensures that the base portion 46 and the web 32 are not in exactly parallel alignment.
  • the arm 94, the lip 98, and the internal dimensions of the socket may be so configured that it is necessary for removal of the connecting component 62, 64 to rotate the connecting component relative to the post portion 48 as suggested by arrow R such that the inclined surfaces 96a, 96b and the lip 98 do not interfere with one another. It follows that socket 66 cannot inadvertently be removed from post portion 48 without overcoming the resistance to deflection of arm 94.

  • the further (third and fourth) mounting brackets 78, 80 may each include a slot or cut out in which a lower part of a side member 68 is accommodated.
  • an important advantage of the arrangement of WO2008/015440 is the facility to adjust the mounting of the head rail by longitudinal movement of the socket 66 on the post portion 48, thereby to accommodate different constructions of the frame 10.
  • one or more spacing elements 88 may be provided which are configured to sit between the head rail 24 (more specifically, the respective connecting component 62, 64) and the frame 10. This allows for the case where the combined length ⁇ of the socket 66 and the depth d of the base portion 46 is greater than the depth of the frame 10 (that is, the distance from the front face 12a, 14a, 16a, 18a to the surface of the glass), or, for the case where the length of the post portion 48 is greater than the depth of the frame 10.
  • each spacing element 88 can be provided each having a different depth W .
  • a spacing element of appropriate depth wit is thus possible to ensure that no gap, or substantially no gap, is present between the internal or rear face of the head rail 24 (or, more specifically, the rear face of the connecting component 62, 64) and the front face of the frame 10.
  • the head rail 24 may be constructed to have a lower face which, by use of spacing elements 88 of appropriate depth, extends to meet the glass pane 20a without any significant gap.
  • Each spacing element 88 includes edge wall portions 88a, 88b which define a recess or cut-out which is sized and shaped to conform to the external shape of the socket 66.

  • End caps 92 may be provided to close the ends of the head rail 24 and provide a more aesthetically pleasing finish.
  • the post portions 48 of the first and second mounting formations 38, 40 are inserted into the respective apertures 50 of the mounting brackets 28, 30.
  • latching formations 54 are present (as is preferred)
  • the post portions 48 are inserted to an extent sufficient to cause the latching formations 54 to engage the edges of the web 32a which define aperture 50.

  • the head rail 24 carries all the components of the blind, including the shade portion, tilt mechanism and so on.
  • the head assembly (head rail 24 in the illustrated embodiments), being substantially rigid, serves to ensure that the mounting brackets 28, 30 cannot move laterally (parallel to upper frame member 12). Side members 68 prevent movement of the mounting brackets 28, 30 parallel to frame side members 16, 18.
  • the combination of these integers in effect provides a framework which retains the mounting brackets 28, 30 in their intended position and assists in the transfer of operating forces from the head rail, without allowing such forces to be transferred to the glass pane 20a through potentially relatively sharp edges of the mounting brackets 28, 30. Instead, forces are transferred primarily through the base portions 46 of the mounting formations 38, 40.
  • the tool 100 comprises a body portion 102 having an upper face 104, a lower face 106 and side walls 108A-D. Walls 108A-D define concave or indented finger-grip portions 110A-D which facilitate holding of the tool in a users hand.
  • the tool 100 includes a void 114.
  • This void 114 is not provided for functional reasons associated with the use of the tool but for manufacturing reasons such as weight and material saving or moulding considerations. Therefore the shape of void 114 is not relevant to the present invention. However, it is noted that the presence of the void 114 illustrates that it is not necessary for the lower face 106, which rests in use against the window pane, to be continuous across the full extent of the body portion 102 or the tool 100.
  • the body portion 102 further includes surfaces, lands or web portions 116 which are spaced from and approximately parallel to lower face 106.
  • the spacing of the lands 116 from the lower face 106 is chosen to be not less than the depth "d" of the base portion 46 of the mounting formations 38, 40 ( Figs 3 and 5 ).

  • the internal shape of the cavities 118A, 118B is determined by the shape of the upstands or post portions 48 of the mounting components 38, 40.
  • the shape of the post portions 48 for mounting at respective sides of a window will be the same, and it follows that the internal shape of the cavities 118A, 118B will be the same.
  • this is not necessarily so and if the shapes of the post portions differ, the internal shapes of the cavities 188A, 188B may also to differ if necessary to accommodate the differences in shape of the post portions 48.
  • These post portions 48 as illustrated are approximately square in cross-section and consequently the cavities 118A, 118B are similarly square.
  • the cavities 118A, 118B will also be constructed to be rectangular or polygonal in shape.
  • the internal size and shape of the cavities 118A and 118B is selected to be a close fit with the external shape of the post portions 48 without, preferably, being a close friction fit or interference fit.
  • the shape of the cavities 118A, 118B should closely follow that of the post portions 48, the post portions 48 should be able to move sufficiently freely in the longitudinal direction so that the post portions 48 can easily be inserted into, and removed from the respective cavities 118A, 118B when desired by a user.
  • Some degree of frictional engagement between the walls of the cavities 118A, 118B and the post portion 48 may be desirable so that the post portion 48 does not fall out of the cavity 118A, 118B unless the installer so intends. It will be appreciated that, although desirable, it is not essential for all of the cavity walls 118A1-4, 118B1-4 to provide a close fit with the post portion 48, provided only that during use movement of the post portion 48 with respect to the cavity 118A, 188B is maintained at a minimum and that accurate positioning of the mounting formation 38, 40 is not prejudiced.
  • a bracket 28, 30 is mounted on a post portion 48 of a mounting formation (38, 40) (if not already so mounted) and the post portion 48 is inserted into an appropriate cavity 118A, 118B.

  • the respective post portion 48 is received into cavity 118A of tool 100 so that bracket 28, 30 and lands 116 are opposed.
  • the tool 100 is then used to offer the mounting component 38, 40 up to the glass pane 20a in the vicinity of the upper left corner so that the surface 46a closely approaches, or contacts, the glass pane 20a.
  • the tool 100 is then urged by the user to move laterally so that the finger portion(s) 34, 36 of the bracket 28, 30 slide between the bead(s) 22 and the glass pane 20a.
  • the tool is urged to move laterally until walls 108A, 108C come into contact with frame members 12, 16.
  • the location of the cavity 118A, 118B within the tool is arranged such that, when the walls 108A, 108C are in contact with frame members 12, 16, the mounting formation (38, 40) is in its desired final location, in particular with a view to ensuring that connecting component 62, 64 is properly located in its final position when the socket 66 of the connecting component 66 is mounted on post portion 48.
  • mounting of the mounting formation (supporting component) (38, 40) at the top right hand side of the window follows the same procedure, except that the post portion 48 of the mounting component 38, 40 is received in cavity 118B and the tool 100 is urged to move laterally until walls 108B, 108D are in contact with frame members 12, 18.
  • positioning of the mounting components 38, 40 is automatic in the sense that the installer is not required to make any measurements as to the required position of the mounting components either before or after installation thereof. This makes installation exceedingly quick, which is commercially very advantageous. Furthermore, only a minimum of force is required by a user to urge the mounting components into their position of use.
  • the tool 100 further comprises third and fourth cavities 120A, 120B which in use accommodate third an fourth mounting brackets (further (third and fourth) mounting components) 78, 80.

  • the mode of use of the tool 100 with the third and fourth mounting components is similar to that with the first and second mounting components: the return portion 84 is received in the respective cavity 120A, 120B and the tool 100 is used to offer the third or fourth component 78, 80 up to the glass pane 20a and to slide the relevant finger 82 between the glass pane 20a and the bead 22 at the lower corners of the window.
  • the third and/or fourth mounting components 78, 80 are usefully used for securing operating cords of a blind. This has the advantage, for example in the case of Venetian or pleated blinds that the operating cords can be pre-tensioned in the factory prior to installation. Tensioning of the cords by an installer is thus not required, thereby improving the speed, efficiency and accuracy of the blind installation.
  • the tool 100 comprises at least one formation 124 (and preferably two formations 124A, 124B) which are configured to co-operate in use with the side member retaining means (clips) 72 for securing the respective side members 68 in their position of use.

  • Head portion 74 of the clip 72 is received into formation 124A, 124B with the lower surface 106 of tool 100 also resting against the glass pane 20a. Wall portion 124A1, 124B1 of the tool 100 is then used to urge the clip 72 laterally so that finger portion 76 slides between the bead 22 and the glass pane 20a and the head portion 74 engages the side member 68.

  • the shade portion of the blind is secured in its "raised” (i.e. most compact) configuration.
  • Simple securing means such as elastic bands may be used for this purpose.
  • the head rail 24 is mounted in position by offering sockets 66 of the connecting components 62, 64 up to the respective post portions 48 so that the post portions are received into the sockets. At this stage the securing means are removed (such as by simply cutting them) and the blind shade portion can be lowered.
  • sockets 66 are put in place at this time, if necessary while deflecting the blind shade portion to a position in which it does not obstruct this step (such as by tilting the laths of a Venetian blind into their generally vertical, shading, position).
