    DETAILED DESCRIPTION

    [0037] Turning first to FIGS. 1a to 1c, there is shown an end view of a first embodiment of louver, generally indicated 10, for use in a window, door, shutter, blind or similar. The louver 10 comprises an elongate body 12, the body 12 comprising parallel upper face 14 and a lower face 16, and opposed rounded side faces 18 and 20. The body 12 also comprises two end faces 22 and 24. A slot 26 is provided in side face 20 (shown with broken line 27 on FIG. 1b), said slot 26 extending the length of body 12 between the end faces 22 and 24.

    [0038] The slot may take any shape into which the wrapping can be inserted. Slot 22 has a generally rectangular profile, though alternatively this may be U-shaped, or horseshoe-shaped profile. The profile of slot 22 extends into the body from an opening, the height of the slot from the opening remains constant. In alternative embodiments, the profile may narrow as it extends into the body, for example a U shape or V shaped profile. Further still, the profile may include a portion having a height greater than that of the opening, for example a C shape or horseshoe-shaped profile. As shown most clearly in FIG. 1a, the side face 18 and 20 are rounded, and so face 20 tapers in towards the opening of the slot 26.

    [0039] A wrapping, generally indicated 30, is provided about the body 12. The wrapping 30 extends the full length of the body 12, and is aligned with the end faces 22, 24. The wrapping 30 encircles the body 12 entirely, so as to completely cover it. Free ends of the wrapping, indicated 32 and 34 are tucked into, and retained in, the slot 26.

    [0040] Retaining member, generally indicated 36, is disposed in slot 26, and is dimensioned so as to clamp or grip the free ends 32 and 34 of the wrapping 30 against the inside surface of the slot 22, thus retaining the wrapping 30 in place. Each free end 32 and 34 is clamped against a different inside surface of the slot 26 by contact with the retaining member 36. The retaining member extends the full length of the body 12 between the end faces 22 and 24. In this case the slot 26 has a substantially rectangular profile and the retainer 36 is substantially oval.

    [0041] FIG. 2 shows an alternative embodiment of louver to that shown in FIGS. 1a-c. The louver, generally indicated 40, differs from the louver described in relation to FIGS. 1a-c only in that the opposed top and bottom faces, indicated 42 and 44 are outwardly-curving, rather than parallel.

    [0042] FIGS. 3a, 3b and 3c shows an alternative embodiment of louver, generally indicated 50. The louver 50 comprises a body 52 which has a cross section that comprises upper and lower offset rectangles, referred to by the numerals 54 and 56 respectively. Upper rectangle 54 comprises a longer upper face 58, shorter lower face 60 and opposed side faces 62 and 64. Lower rectangle 56 comprises a longer lower face 66, shorter upper face 68 and opposed side faces 70 and 72.

    [0043] Body 52 further comprises two end faces 74 and 76.

    [0044] A slot 78 is provided in side face 62 of the upper rectangle 54, flush with the shorter upper face 68 of the lower rectangle 56. Said slot 74 extends the length of body 52 between the end faces 74 and 76, as shown by broken line 75 in FIG. 3c A wrapping, generally indicated 80, is provided about the body 52. The wrapping 80 extends the full length of the body 52, and is aligned with the end faces 74, 76. The wrapping 80 encircles the body 52 entirely, so as to completely cover it. Free ends of the wrapping, indicated 82 and 84, are tucked into the slot 26.

    [0045] Retaining member, generally indicated 90, is disposed in slot 78, and is dimensioned so as to clamp the free ends 82 and 84 of the wrapping 80 against the inside surface of the slot 78, thus retaining the wrapping 80 in place. The retaining member extends the full length of the body 52 between the end faces 74 and 76.

    [0046] A demonstration of louvers according to the present invention in use is shown in FIG. 4, which shows a schematic perspective view of a shutter, generally indicated 100. Shutter 100 comprises opposed stiles 102, 104 and opposed rails 106, 108. A plurality of louvers 110 are hingedly mounted to the opposed stiles 102, 104. An actuating bar 112 is hingedly mounted to an outer edge of each louver 110. The louvers 100 are all disposed at an angle parallel to one another, and the respective angle of the louvers 110 can be adjusted by manually raising or lowering the actuating bar 112.

    [0047] In use the shutter 100 may be installed in the window of a property so that the actuating bar 112 is internal to the property, and the slots (not shown) on the louvers 110 are external, so as not to be visible from within the property.
