Abstract

A molded panel resembling a natural wickerwork panel, a furniture article comprising such a panel and a method for its manufacture, the panel comprising a plurality of warp strands and a plurality of weft strands interlacing the warp strands, such that at locations where warp and weft strands intersect they form together an integrated, solid molded material location.

First claim

The invention claimed is:

1. An injection molding mold for manufacturing a molded unitary furniture article integral with at least one molded panel mimicking natural wickerwork, the mold comprising:
a top mold member; and
a bottom mold member;
wherein each of the top mold member and the bottom mold member having at least one section that is formed with an array of grooves that complement each other and form together warp shaped channels and undulating weft shaped channels, allowing molten polymer material to flow into the channels to give rise to desired wicker strands; and
blade elements mutually projecting from edges of the grooves of the top mold member and the bottom mold member, the blade elements being configured so as to create fine gaps between at least several neighboring warp wicker strands and undulating weft wicker strands such that neighboring weft wicker strands are distanced from one another and the gaps form a continuous path extending between the undulating weft wicker strands, the path being parallel to the warp wicker strands;
wherein in one or both of the second and bottom mold member, a height of a weft-shaped channel is vertically spaced from a height of a neighboring weft-shaped channel at a location intersecting a warp-shaped channel, and whereby undulating neighboring weft strands give rise to a vertical gap extending between a space adjacent each warp strand and zeroing at a locations where the neighboring weft strands tangentially intersect each other.

2. The mold of claim 1 , wherein the blade elements vertically project from respective edges of the grooves of the top mold member and the bottom mold member, towards each other, such that at an assembled position of the mold oppositely projecting blade-like elements engage one another.

3. The mold of claim 2 , further comprising spacer segments between neighboring weft grooves, giving rise to flow of molten material in-between adjoining strands, resulting in contact points therebetween which rigidify the at least one panel.

4. The mold of claim 1 , further comprising complimentary top and bottom mold members, associated with a front face of the at least one panel and with a rear face thereof, respectively, the mold members being securable to one another at fixed positions, with at least one molten material in-flow port, and wherein each complimentary mold is formed with grooves corresponding with warp and weft wicker strands of the panel, said grooves complimenting each other and are formed with blade elements such that at an assembled position of the mold they substantially engage with blade elements of an opposite mold, thereby giving rise to substantially closed channels for molding the warp and weft strands.

5. The mold of claim 1 , configured for forming an integrated, solid molded material location at the intersection points of the warp-shaped channels and weft-shaped channels when molten polymer material is flown into the mold.

6. The mold of claim 1 , wherein each of the top mold member and the bottom mold member is configured to mimic a different pattern of natural wickerwork surface from one another.

7. The mold of claim 1 , wherein said at least one section is at least partially circumferenced by a frame channel to form a rigid frame, at least partially circumferencing the panel.
