Abstract

Provided is a molded panel having at least one surface resembling a knit-like pattern, said panel comprising a plurality of stitches at least partially interconnected through connecting members wherein at locations where the stitch strand and the connecting member intersect they form together an integrated, solid molded material location and wherein the panel comprises through going apertures extending therethrough.

First claim

The invention claimed is:

1. An injection molded polymeric panel having at least one surface resembling a knit-like pattern comprising a polymeric three-dimensional structure resembling interwoven yarn knitted-stitches, said three-dimensional structure having a knit-like structure comprising a plurality of stitches at least partially interconnected through connecting members forming together said knit-like pattern, wherein at locations where the stitch strand and the connecting member intersect they form together an integrated, solid integrally-molded material location, and wherein the panel comprises through going apertures extending therethrough, the panel being a unitary-molded panel.

2. The molded panel in accordance with claim 1 , wherein the panel comprises a base layer configured to provide the panel with its structural continuity and a three dimensional, protruding from the base, tactile layer at least over one face thereof, constituted by stitch patterns on the at least one face of the panel and providing the panel with a knit-like visual effect, wherein the base layer is at least partially perforated, with the perforations being constituted by the space in-between the connecting members of the knit pattern.

3. The molded panel in accordance with claim 2 , wherein the base layer is at least partially constituted by at least the connecting members extending between the stitches at least in each row of the pattern.

4. The molded panel in accordance with claim 2 , wherein the knit-like stitches on the tactile layer are arranged in columns, having a varying knit-like pattern with a gradually expanding spacing in each stitch of the same longitudinal strap constituting a knit column, said columns being interconnected with the adjacent column on either side through the connecting members.

5. The molded panel in accordance with claim 2 , the panel having two similar faces.

6. The molded panel in accordance with claim 2 , the panel having two faces fitted with tactile layer, each layer mimicking a different pattern of knitted surface.

7. The molded panel in accordance with claim 2 , wherein the knit like pattern is integrally molded with a frame having a non knit-like surface.

8. The molded panel in accordance with claim 1 , wherein the panel is molded in different three-dimensional shapes.

9. The molded panel in accordance with claim 1 , wherein forces over the knit stitches and their interconnecting strands are substantially homogenously distributed.

10. The molded panel in accordance with claim 1 , wherein the knit-like pattern is comprised of a plurality of curved columns of knit stitches connected to each other by integrally molded connecting members, the plurality of curved columns defining the outer surface remain constant in number from the start of the knit-like pattern to the end thereof and wherein the through going apertures are constituted by the space in-between the connecting members of the knit pattern.

11. The molded panel in accordance with claim 2 , wherein the molded panel comprises a knit-like surface having an axial stability, such that the knit-like tactile layer maintains its knit-like pattern having generally same geometrical structure and dimensions, when deformed.

12. The molded panel in accordance with claim 2 , wherein the at least one tactile layer resembles a yarn knitted stitches in any desired knitting pattern.

13. A molded hollow article, having at least one surface resembling a knit-like pattern, wherein the article has a three dimensional spatial configuration having a sufficient rigidity to carry a load thereon wherein the knit-like pattern is constituted by a panel in accordance with claim 1 having a curved shape.

14. The molded hollow article in accordance with claim 13 , wherein the knit-like pattern is comprised of a plurality of curved columns of knit stitches connected to each other by integrally molded connecting members, the plurality of curved columns defining the outer surface remain constant in number from the start of the knit pattern to the end thereof.

15. The molded hollow article in accordance with claim 13 , wherein the number of knit stitch columns is maintained constant while the width of the stitches in each row gradually increases and decreases as required to follow the curvature of the three dimensional shape.
