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. A mold for manufacturing a molded panel, by injection molding the mold comprising:
a second mold member; and
a bottom mold member;
wherein each of the second mold member and the bottom mold member is formed with an array of grooves that complement each other and form together warp and weft shaped channels, allowing molten polymer material to flow into the warp shaped channels and undulating weft shaped channels, to give rise to desired wicker strands; and blade elements mutually projecting from edges of grooves of the array of grooves of the second mold member and the bottom mold member, the blade elements being configured so as to create fine gaps between at least several ones of the neighboring warp wicker strand 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 according to claim 1 , wherein said blade elements vertically project from respective edges of grooves of the array of grooves of the second mold member and the bottom mold member, towards each other, such that at an assembled position of the mold oppositely projecting blade elements engage one another.

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

4. The mold according to claim 2 , further comprising spacer segments between neighboring ones of the weft grooves, giving rise to flow of molten material in-between adjoining ones of the wicker strands, resulting in contact points therebetween which rigidify the molded panel.
