BRIEF SUMMARY
BRIEF DESCRIPTION OF THE INVENTION
The present invention relates to a fabric blind slat. In particular, the present invention relates to a fabric blind slat for venetian blinds.
FIELD OF THE INVENTION
Blinds for covering windows and other light transparent surfaces are available in a variety of different forms and materials depending on the particular visual appearance desired. The known items for controlling the amount of light through a transparent surface include venetian blinds, roller blinds and vertical blinds.
Fabric blinds are popular blinds for use in buildings and are extensively used in vertical blinds for their aesthetic appeal.
However, a problem exists for the use of fabric in horizontal blind slats since the fabric is not strong enough to lie in a horizontal plane without sagging. Hence, at the present time slats are usually made of metal and/or wood.
The present invention seeks to overcome the abovementioned problem.
SUMMARY OF THE INVENTION
In accordance with a first aspect of the present invention there is provided a fabric blind slat including an elongated strip of fabric characterised in that the strip of fabric has at least one longitudinally extending pocket on a longitudinal edge into which a relatively rigid support member is insertable.
In accordance with a second aspect of the present invention there is provided a fabric venetian blind assembly characterised by: fabric characterised in that the strip of fabric has at least one longitudinally extending pocket on a longitudinal edge into which a relatively rigid support member is insertable:
In accordance with a third aspect of the present invention there is provided a method for the assembly of a fabric venetian blind characterised by including the following steps: characterised in that the strip of fabric has at least one longitudinally extending pocket on a longitudinal edge; tape.
BRIEF DESCRIPTION OF THE DRAWINGS
The present invention will now be described, by way of example, with reference to the accompanying drawings; in which:
FIG. 1a is an upper perspective view of a fabric blind slat in accordance with the present invention;
FIG. 1b is a partly cut away second upper perspective view of the fabric blind slat in accordance with the present invention;
FIG. 1c is an end view of the fabric blind slat in accordance with the present invention;
FIG. 2a is a perspective view of a first embodiment of a fabric venetian blind assembly in accordance with the present invention;
FIG. 2b is a perspective view of a second embodiment of a fabric venetian blind assembly in accordance with the present invention.
DESCRIPTION OF THE INVENTION
There is shown in FIG. 1a, an upper perspective view of a fabric blind slat 10. The fabric blind slat 10 may be made from any suitable fabric including but not limited to polyester yarn, acrylic yarn, nylon, cotton, wool, polypropylene and any other fabric suitable for use in fabric blinds.
The fabric blind slat 10 includes an elongated central strip 12 of suitable fabric material. The slat 10 has a longitudinally extending pocket 14 at a first longitudinal edge 16 of the blind 10. Similarly, the slat 10 has a longitudinally extending pocket 14 at a second longitudinal edge 18 of the blind 10. The longitudinally extending pocket 14 is closed longitudinally at a first side 20 and a second side 22 as shown in FIG. 1.
There is shown in FIG. 1b, a partly cut away second upper perspective view of the fabric blind slat 10 having typically two longitudinally extending pockets 14. The pockets 14 have a longitudinally extending space 15 within the fabric blind slat 10. A support member 24 of relatively rigid material is inserted within the space 15 of the pockets 14.
This relatively rigid member 24 is typically a rod made from fibreglass, a plastics material such as PVC or, nylon, metal, wood, or any other suitable material to increase the strength and to provide support of the slat 10. Typically, the relatively rigid member 24 is also resilient. There is also shown in FIG. 1c an end view of the fabric
