  • the toothed wheel 105A and the end of the shaft 106 may also be seen in Fig. 7 , as well as an edge of the surface 132A.
  • the handle 103 may be directly attached to a blind for a window, but in the illustrated examples, the handle is operatively connected to a blind by a magnetic mechanism. Therefore, as shown in Fig. 1 , the handle comprises a plurality of magnets 108A, 108B, 108C and 108D, and a rail 109 attached to the blind 104 also contains a plurality of magnets 110A, 110B, 110C and 110D.

  • the magnets 110A to 110D of the rail 109 are arranged so that their poles which face the magnets 108A to 108D of the handle 103 are attracted to the magnets of the handle.
  • the magnets of the handle may have north poles facing the rail, and the magnets of the rail may have south poles facing the handle.
  • the magnets in the present example are arranged in groups of two in the handle and in the rail, but groups of more or less than two magnets may be used in other embodiments.
  • the apparatus 101 may also comprise a first transparent panel 111, which may be a pane of glass or a sheet of a transparent polymeric material used to form a window.
  • the panel 111 has a first side 120A facing the handle 103 and a second side 120B facing the rail 109.
  • the supporting rails 130A and 130B supporting the toothed tracks 102A and 102B may be fixed to the first side 120A of the panel 111, for example by an adhesive or by a clips as will be described below.
  • a first slide track 112A of the apparatus 101 is fixed adjacent to the second side 120A of the panel 111 and a second slide track 112B is fixed adjacent to the second side 120B of the panel 111 and arranged parallel to the first track.
  • the tracks 112A and 112B have smooth surfaces 113A and 113B respectively arranged to face end portions 114A and 114B of the rail 109, and the rail 109 has sliding surfaces 121A and 121 B configured to slide along the first and second slide tracks 112A and 112B (in a direction into and/or out of the page in the view of Fig. 1 ).
  • the rail 109 has a middle portion having a front face 122 facing the panel 111.

Consequently, the first and second tracks 112A and 112B prevent the rail 109 from contacting the panel 111.
  • the apparatus 101 also comprises a second transparent panel 115 arranged parallel to the first transparent panel 111.

  • the second slide member 112B and the second barrier member 116B may form a gap 202 through which the end portion 114B of the rail extends.
  • the end portions 114A and 114B are dimensioned to be a loose fit within the gaps 202. Consequently, if the magnetic interaction between the magnets of the handle 103 and the magnets of the rail 109 are broken, the rail 109 is free to fall within the apparatus 101 until it comes to rest on a horizontal surface. This will be further described below.
  • a central rear surface 119 of the rail 109 faces the second panel 119 and a respective surface 124A and 124B of the end portions 114A and 114B of the rail 109 face the barrier members 116A and 116B.
  • the central rear surface 119 of the rail 109 is spaced from the surfaces 124A and 124B of the end portions 114A and 114B by a distance that is smaller than the spacing between the surfaces 118A and 118B of the barrier members 116A and 116B and the face 117A of the second panel 115. Consequently, in situations where the magnetic interaction between the magnets of the handle and the magnets of the rail is broken, the first and second barrier members 116A and 116B prevent the rail contacting the second transparent panel 115.
  • the second panel 115 is spaced from the first panel 111 by spacer bars 125A and 125B extending between the two panels 111 and 115 along two opposing edges of the panels.
  • first slide track 112A and the first barrier member 116A form an integral part of the first spacer bar 125A.
  • the second track 112B and the second barrier member 116B form an integral part of the second spacer bar 125B.
  • the slide tracks 112A, 112B and/or the barrier members 116A, 116B may be formed separately.
  • the spacer bars may be extruded in a first material and the slide track and/or the barrier members may be formed of different materials to the first material.
  • the spacer bar may be extruded from a polymeric material and the slide track may be formed of extruded aluminium.
  • FIGS. 2A and 2B End portions of an alternative apparatus 101 are shown in Figs. 2A and 2B .
  • the apparatus of Figs. 2A and 2B is the same as the apparatus 101 of Fig. 1 except for it has a different rail 109A.
  • a first end 201A of the rail 109A with an alternative first end portion 114C is shown in Fig 2A and the opposite second end 201 B of rail 109A with a similar alternative end portion 114C is shown in Fig 2B .
  • the rail 109A has a first end 201A extending through a first gap 202 defined by the first slide track 112A and the first barrier member 116A.

  • the rail 109A has an interlocking member 204 extending from its end 201A toward the second transparent panel 115, and the lip 203 prevents the interlocking member 204 from being removed from the first gap 202.
  • the opposite second end 201 B of the rail 109A is similarly configured to the first end 201A. Therefore the rail 109A has a second end extending through a second gap 202 defined by the second track 112B and the second barrier member 116B.
  • the second barrier member also comprises a lip 203 extending away from the second transparent panel 115 and the rail 109A has another interlocking member 204 extending from its second end toward the second transparent panel 115. Therefore the lip 203 prevents the interlocking member 204 of the second end of the rail from being removed from the second gap 202 defined by the second slide track 112B and the second barrier member 116B.
  • the rail 109A In normal use, the rail 109A is maintained in position by the magnetic interaction between its magnets 110A to 110D and the magnets 108A and 108D of the handle 103. However, in situations where the magnetic interaction between the two sets of magnets is broken, mechanical interaction between the interlocking member 204 at the first end of the rail and the lip of the first barrier member 116A prevents the first end 201A from passing through the gap 202, and similarly the interaction between the interlocking member 204 at the opposite second end of the rail 109A and the lip of the second barrier member 116B prevents the second end from passing through the gap 202.
  • FIGS. 2C and 2D End portions of an alternative apparatus 101 are shown in Figs. 2C and 2D .

  • the interlocking member 204A may be configured in the same way as interlocking member 204 of rail 109A.
  • the interlocking member 204B extends from the first end 201C of the rail 109B towards the first panel 111 and in normal use it extends into a space behind the slide rail 112A. Therefore the first and second interlocking members 204A and 204B extend from the end portion 114E of the rail 109B to form a T-shape as shown in Fig 2C .
  • an interlocking member 204B extends from the second end 201 D of the rail 109B towards the first panel 111 and in normal use it extends into a space behind the slide rail 112B. Therefore the first and second interlocking members 204A and 204B extend from the second end portion 114E of the rail 109B to form a T-shape as shown in Fig 2D .
  • the second interlocking member 204B may interact with the slide track 112A, and the first interlocking member 204A may interact with the barrier member 116A, such that the end 201A of the rail 109B is prevented from passing through the gap 202 formed by the first slide track 112A and the first barrier member 116A.
  • a first end 201 E of a further alternative rail 109C is shown in a perspective view in Fig. 3 .
  • the two ends of the rail 109C are similarly configured and therefore only the illustrated end will be described.
  • the rail 109C has the same construction as rail 109B but differs in the detail of its interlocking members.
  • rail 109C has a central portion 331 that has substantially the same width across its whole length and end portions 114E that have a smaller width.

  • Each of the interlocking members 204A, 204B may have a cylindrical outer surface which extend around axes that are perpendicular to the length of the rail.
  • the interlocking members 204A, 204B do not touch any other components of the apparatus, and they perform no function.
  • the interlocking members 204A and 204B may impact upon surfaces such as those of the spacer bar 125A, the slide rail 112A and the barrier member 116A.

  • the interlocking members and the end portions of the rails may be moulded as a single item.
  • the rail 109D has interlocking members 404A and 404B that are pivotally mounted on the end portion 114E.
  • Axles 401 extend perpendicularly from the end portion 114E and the axles support interlocking members 404A and 404B, which are provided in the form of moulded wheels.
  • the wheels may be formed of a suitable polymer material such as nylon and the axles 401 may be formed of a metal.
  • Two of the interlocking members 404A extend on parallel axels to one side of the end portion 114E and two interlocking members 404B extend on parallel axels to the other side of the end portion 114E.
  • the wheels 404A and 404B are arranged to be free to rotate on their axles.
  • the interlocking members 404A and 404B may impact upon surfaces such as those of the spacer bar 125A, the slide rail 112A and the barrier member 116A. However the rail 109D will not become jammed because the interlocking members 404A, 404B are able to roll over these surfaces. Consequently the rail 109D is free to fall in such instances.
  • the apparatus 101 comprises a window unit that may be used as a window in a building, or vehicle such as a caravan.
  • the window unit being double glazed unit (insulating glazing unit) having a blind 104 located between two transparent panels 111 and 115.
  • one end of the blind 104 may be attached to a fixed rail 502 and the opposite end may be attached to the moveable rail 109.
  • the fixed rail 502 is extends horizontally across the top of end of the blind 104.
  • the fixed rail 502 may be permanently fixed to a spacer bar 503 that extends across the top edge of the panels 111 and 115.
  • the handle 103 may be horizontally orientated and due to the magnetic attraction between its magnets and those of moveable rail 109, the moveable rail 109 is held in a horizontal orientation. As the handle 103 is moved, the rail 109 is moved due to the magnetic attraction between the magnets of the handle 103 and the magnets of the rail 109.
  • the handle 103 extends between the toothed tracks 102A and 102B, so that it is perpendicular to the toothed tracks and the toothed wheels 105A and 105B are in engagement with the toothed tracks.
  • the blind 104 is shown in Figs. 5A and 5B in a partially closed configuration such that about two thirds of the panels 111 and 115 are obscured by the blind.
  • the blind may be further opened or closed from the illustrated configuration by moving the handle 103 upward or downwards respectively. Such a movement causes the toothed wheels 105A and 105B to roll along the toothed tracks 102A and 102B respectively.
  • the toothed wheel 105A has the same dimensions as toothed wheel 105B, and the two toothed wheels are connected such that they rotate at the same rate, as described above.
  • the handle 103 is maintained in an orientation perpendicular to the toothed tracks 102A and 102B during its movement.
  • the blind 104 is formed of a pleated sheet of material as illustrated in Fig. 5C .
  • the blind 104 may be attached to the rail 109 by forcing several pleats of the material through a slot 504 into a compartment 505 formed in the rail.
  • other types of blind may be used.
  • the blind is a cellular blind.
  • the blind is a roller blind.
  • the bottom end of the blind 104 may be attached to a fixed rail located along the bottom edge of the apparatus and the moving rail may be attached to the top end of the blind.
  • the apparatus 101 is arranged in an orientation that is 90 degrees rotated from that shown in Figs. 5A and 5B so that the moving rail 109 extends vertically and the blind closes by a horizontal movement of the rail 109.
  • Each of the toothed rails 102A and 102B may be formed of a single length of moulded material, but, beyond relatively short lengths, such toothed rails are expensive to produce.
  • This problem may be overcome by forming the first toothed track from a first toothed part (or first module) having one end connected to one end of a second toothed part (or second module), wherein the one end of the first toothed part and/or the second toothed part defines a recess containing a connecting tab connecting the first toothed part to the second toothed part. That is, the toothed track may be formed of modules, or parts, connected end to end.
  • FIG. 6A An example of a toothed part, or module, 601 which may be connected with a similar module 601 to form a longer toothed track is shown in the bottom view of Fig. 6A , the side view of Fig. 6B , the top view of Fig. 6C and the end view of Fig. 6D .
  • the module 601 has teeth 602 extending from one side and a recess 603 formed in the opposite side at a first end 604 of the part 601. As may be seen by comparing Figs. 6A and 6C , the recess does not extend completely through the depth of the track 601, and so there are teeth 602A which extend over the portion of the track that defines the recess 603.
  • the module 601 has a connecting tab 605 at its second end 606.
  • the tab 605 has a similar outline to that of the recess 603 such that the tab 605 is able to be located in a recess 603 of a similarly formed module 601.
  • the connecting tab 605 may be an integral part of the module 601.
  • the whole of the module may be formed by moulding a suitable polymeric material, such as a polymeric material comprising acetal (or polyoxymethylene), or by casting a suitable metal, such as aluminium alloy.
  • the connecting tab 605 has an enlarged head portion 607 and a relatively narrow neck portion 608.
  • the recess 603 is correspondingly shaped with a relatively narrow opening 609 at the first end 604 to receive the neck portion 608 and a wider opening 610 inset from the first end to receive the head portion 607.
  • the module 601 is shown connected to an identically formed second module 601' in the top view of Fig. 6E and bottom view of Fig. 6F .
  • the connecting tab 605 of module 601 is located within the recess 603 of the second module 601'. It will be understood that other similar modules may be connected to the recess of the first module 601 or the connecting tab 605 of the second module 601'. Consequently, a toothed track of longer lengths may be formed by connecting many modules 601 together.
  • end ones of the modules may be cut to length and therefore any required length of toothed track may be formed from a sufficient number of the modules 601. Because only a relatively small mould is used to create the modules, this method enables long tracks of various lengths to be produced at a relatively low cost.
  • FIG. 8A An alternative example apparatus 101A is shown in the front view of Fig. 8A and the rear view of Fig. 8B .
  • the apparatus 101A is similarly formed to apparatus 101 of Fig. 1 except that it has a blind 104 that has a first end attached to a first moveable rail 109E and a second end attached to a second moveable rail 109F.
  • the rails 109E and 109F may similar to each other and similarly configured to the above-described rails 109, 109A, 109B, 109C or 109D.
  • the apparatus 101A also has two handles 103A and 103B which may be similarly configured to the handle 103 of Fig. 1 .
  • each of the handles 103A, 103B has a toothed wheel 105A at a first end and a toothed wheel 105B at a second end.
  • the toothed wheels 105A are located on a toothed track 102A and the toothed wheels 105B are located on a toothed track 102B.
  • the first handle 103A has magnets magnetically attracted to magnets located in the first rail 109E
  • the second handle 103B has magnets magnetically attracted to magnets located in the second rail 109F.
  • the handles 103A, 103B and hence the rails 109E, 109F are horizontally arranged.
  • the position of the top end of the blind 104 may be adjusted by moving the upper handle 103B and the bottom end of the blind may be adjusted by moving the lower handle 103A.
  • the blind may be fully closed by moving the upper handle 103B upwards and the lower handle 103A downwards.
  • both handles 103A and 103B may be moved upwards or downwards as far as they can go to fully open the blind.
  • the apparatus 101A may be rotated through 90 degrees such that the rails 109E and 109F and the handles 103A and 103B extend vertically.
  • the portion of the window unit 101A that is obscured by the blind 104 may be moved from left to right and right to left using the handles 103A and 103B.
  • FIG. 9 An end portion of an apparatus 101 B is shown in the cross-sectional view of Fig. 9 , a perspective cross-sectional view of Fig. 10 and a front view of Fig 11 . It should be understood that the apparatus 101 B like apparatus 101 and 101A is symmetrical and therefor the apparatus 101 B has a second end portion like that shown in Figs. 9 and 10 .
  • the apparatus 101 B may have all of the features described previously for apparatus 101 and apparatus 101 A. Specifically it has a first handle 103A and a second handle 103B which has magnets (such as 108A and 108B) arranged to magnetically connect with magnets (such as magnets 110A and 110B) of a respective one of two rails 109D.
  • magnets such as 108A and 108B
  • Each handle 103A, 103B has a toothed wheel (such as 105A) at each end and the toothed wheels at each end of a handle are operatively connected to rotate at the same rate; the toothed wheels of each handle being connected by a shaft 106.
  • a toothed wheel such as 105A
  • the apparatus 101B differs from apparatus 101 and 101A in that it has two covers 901 extending over each of its toothed wheels (such as 105A) and over its toothed tracks (such as track 102A).
  • the covers 901 are rigidly attached to the support rails 930 which also support the toothed tracks 102A.
  • the cover 901 is attached to the respective support rail 930 by screws 902.
  • the cover 901 has a surface 903 arranged to be in contact with or in close proximity to an outer surface 904 of the main body 150 of the handles 103A, 103B. In this way, the handles 103A, 103B are prevented from being pulled away from the panel 111 and the teeth of the toothed wheels (such as 105A) are prevented from being lifted out of the toothed track (such as 102A).
  • the brake comprises a block 909 formed of rubber, or synthetic rubber, located on one side of the shaft 106.
  • the block 909 is provided with a surface shaped to fit closely around the cylindrical surface of the shaft 106. In an embodiment, the surface extends approximately half way around the shaft 106.
  • the block may define at least one recess 910 in a face that is on the opposite side to the shaft 106, and the one or more recesses may each contain a spring 911 (such as a helical spring) that is in a compressed state, such that the one or more springs 911 urge the block against the shaft 106 and create a frictional force between the block 909 and the shaft 106.
  • a spring 911 such as a helical spring
  • the frictional force provided by the brakes 107 may prevent the handle (such as handle103A) from moving in the absence of an applied force.
  • the brakes 107 may also prevent some sudden movements of the handle that may otherwise occur due to excessive forces applied by a user, and which would break the magnetic interaction between the magnets of the handle and the magnets of the rail.
  • the apparatus 101 B is shown in Fig. 9 , 10 and 11 located within a window frame 905.
  • the support rails 930 (which support the toothed tracks) may be fixed to the transparent panel 111 by an adhesive.
  • the support rails 930 are attached by means of clips 906.
  • the clips have tongues 908 that are configured to be pushed in between the panel 111 and the window frame 905.
  • FIG. 12A An example of a clip 906 is shown in Fig. 12A and the clip 906 is shown in Fig. 12B attached to a support rail 930.
  • the clip 906 has a flat base portion 1201 from which extend tongues 908 from two adjacent ones of its four sides.
  • Two hooks 1202 extend perpendicularly upwards from the base 1201, with one of the hooks on each side of a tongue 908.
  • a third hook 1203 extends up from the opposite side of the base 1201.
  • the support rail 930 has a width configured to fit between the two hooks 1202 on one side and the third hook 1203 on the other side.
  • the support rail 930 defined shoulders to enable the hooks 1202 and 1203 to clip around and retain the support rail.
  • the apparatus 101 B of Figs. 9 , 10 and 11 is shown again in Fig. 13 after being misused. If the handles 103A and 103B are smoothly pushed by a user, the rails 109D will follow the movement of the handles. However, if a person moves a handle with an excessive force, the magnetic interaction between the handle and the respective rail may be broken by the sudden movement of the handle. Thus, as shown in Fig. 13 , the lower handle 103A may become separated from the lower rail 109D.
  • a rail 109D loses magnetic connection with a handle 103A or 103B the rail is configured to fall within the apparatus until it reaches a horizontal surface provide by the apparatus.
  • the lower rail 109D has fallen onto the horizontal surface provided by a space bar extending along the lower edge of the panels 111 and 115. Because the rail 109D falls down onto a horizontal surface and therefore takes up a horizontal orientation, the magnets of the rail 109D may be simply reconnected with the magnets of the handle 103A by moving the handle 103A down to the rail.
  • the rails 109D are arranged to be free to fall, and therefore the ends of the rail are loosely positioned so that they cannot jam against any surfaces during the fall.
  • this is possible by the rail having interlocking members formed as wheels as described with reference to Fig. 4 , but alternatively the interlocking members may be fixed and rounded as described for rail 109C of Fig. 3 .
  • a method 1400 of assembling a window unit is shown in the flow chart of Fig. 14 .
  • the method comprises a process 1401 in which a first toothed track (such as toothed track 102A) is positioned along a transparent panel (such as panel 111). Typically the first toothed track is positioned adjacent to one edge of the transparent panel.
  • a second toothed track (such as toothed track 102B) is positioned along the transparent panel, parallel to the first toothed track. Typically, the second toothed track is positioned adjacent to an opposite edge of the transparent panel.
  • a first toothed wheel of a handle (such as toothed wheel 105A of handle 103) is positioned on the first toothed track and a second toothed wheel (such as toothed wheel 105B) of the handle is positioned on the second toothed track.
  • the handle is operatively connected to a blind, so that the handle may be used to adjust the position of the blind.
  • the process of operatively connecting a blind to the handle comprises bringing the handle within a magnetic field generated by the magnets of the rail.
  • blocks 1403 and 1404 are shown as two separate blocks in Fig. 14 , it will be understood that the two processes identified by blocks 1403 and 1404 may be performed simultaneously.
  • blocks 1403 and 1404 may be performed in different orders.
  • the handle may be connected to the blind before or after the toothed wheels are located on the toothed tracks.
