Abstract

Provided is an injection molded panel having a top side and a bottom side. The panel is configured with at least an elastic portion, the elastic portion including a plurality of undulating deformable strands intersecting with one another at rigid connecting locations, the rigid connecting locations alternatingly extending at opposite sides of the panel at alternating top peaks and bottom peaks, the peaks defining together the respective top side and the bottom side.

First claim

The invention claimed is:

1. A plastic injection molded panel having a top side and a bottom side comprising at least an elastic portion, said elastic portion comprising a plurality of undulating weft stands in a first direction and a plurality of undulating warp strands in a second direction, wherein the second direction is at an angle to the first direction interlacing said warp strands, wherein the warp strands and weft strands intersect, whereby intersections of the warps strands and the weft strands form molded integrated, rigid connecting locations, said rigid connecting locations alternatingly extending between the top side and bottom side of the panel in both the first direction and the second direction such that a distance is formed between top rigid connecting locations and bottom rigid connecting locations at alternating top peaks and bottom peaks, said top peaks and said bottom peaks defining the respective top side and the bottom side, wherein warp stand portions and weft strand portions extending between said rigid connecting locations are deformable, such that upon receiving an applied load over the top or bottom side of the panel the deformation of the weft and warp strand portions extending between said rigid connecting locations decreases the distance between top side connecting locations and bottom side connecting locations and upon cessation of the applied load the panel at least partially resumes its original shape.

2. The injection molded panel of claim 1 , wherein the deformation between said rigid connecting locations is parallel to the applied load.

3. The injection molded panel of claim 1 , wherein the panel comprises a non-creeping material such that upon cessation of the applied load it resumes its original shape.

4. The injection molded panel of claim 1 , wherein said connecting locations each comprise two or more stands extending therefrom.

5. The injection molded panel of claim 1 , wherein said connecting locations are non-deformable.

6. The injection molded panel of claim 1 , wherein the elasticity parameters are controlled by using multi-component injection, whereby different portions of the panel are molded of different material compositions altering their elasticity.

7. The injection molded panel of claim 1 , wherein the elasticity parameters of the panel are uniform over the entire panel or different at one or more portions thereof or the elasticity parameters are uniform or non-uniform in a directional sense.

8. The injection molded panel of claim 1 , wherein some of said top peaks and said bottom peaks are smoothed/rounded.

9. The injection molded panel of claim 1 , wherein the panel comprises a frame portion integrally molded with the panel or articulated thereto.

10. The injection molded panel of claim 1 , wherein the panel comprises a frame portion integrally molded with the panel or articulated thereto, and wherein the frame is coplanar with at least one of the top side and the bottom side of the panel.

11. A furniture article comprising an injection molded panel in accordance with claim 1 .
