Abstract

A privacy apparatus includes one or more substantially cork panels. Each panel can be configured to provide visual and/or sound privacy for a certain work space. The panel can be supported on a floor via one or more base elements and/or may be reinforced in rigidity and/or strength via one or more supports. Some embodiments of the apparatus can include a first panel and a second panel attached together via one or more supports press fit within openings defined in rear faces of the panels.

First claim

What is claimed is:

1. A method of forming a noise reduction apparatus for mounting adjacent to or above a work space, comprising:
providing cork granules obtained from grinding cork bark;
molding the cork granules in a mold to form a first panel, the first panel having a front face comprised of cork and a rear face opposite the front face, the rear face comprised of cork, the rear face having at least one opening define therein; and
providing at least one support so that each support is extruded to have a base portion that is generally rectangular shaped, the base portion having a flat surface, each support also having at least one projection extending linearly along a length of the base portion and also extending from the base portion so that the at least one projection extends away from the flat surface, the at least one projection having a distal portion and an intermediate portion that is between the distal portion and the base portion, the distal portion being wider or bigger than the intermediate portion, the distal portion being sized to be press-fit within the at least one opening formed in the rear face of the first panel via the cork of the rear face resiliently deforming to accommodate the press-fit of the support within the at least one opening;
wherein the at least one support comprises a first support and the at least one projection includes a first projection and a second projection, the second projection extending away from the flat surface and the first projection extending away from the flat surface such that the first projection extends farther away from the flat surface than the second projection;

press-fitting the first projection of the first support into a first opening of the at least one opening of the rear face of the first panel via the cork of the rear face resiliently deforming to accommodate the press-fitting of the first projection within the first opening for direct attachment of the first support to the first panel; and
press-fitting the second projection of the first support into a second opening of the at least one opening of the rear face of the first panel via the cork of the rear face resiliently deforming to accommodate the press-fitting of the second projection within the second opening for direct attachment of the first support to the first panel.

2. The method of claim 1 , comprising:
mixing the cork granules with a binder prior to molding of the cork granules; and
wherein the molding of the cork granules comprises:
applying heat and pressure to the cork granules in the mold to form the first panel.

3. The method of claim 2 , comprising:
attaching the rear face of the first panel to the support by press-fitting the first projection into the first opening of the at least one opening such that the cork of the rear face resiliently deforms so that the first projection is passable into the first opening and the cork of the rear face resiliently compresses around the first projection to hold the first projection in the first opening, the distal end portion of the first projection being curved or rounded.

4. The method of claim 3 , comprising:
mounting the first support on a wall of a room of a building so the flat surface of the first support directly contacts the wall, the first projection extends away from the flat surface.

5. The method of claim 1 , comprising:
mounting the first support on a wall of a room of a building so the flat surface of the first support directly contacts the wall;
molding the cork granules in the mold to form a second panel, the second panel having a front face and a rear face opposite the front face, the rear face of the second panel having at least one opening define therein;
press-fitting the first projection of the at least one projection into a first opening of the at least one opening of the rear face of the second panel;
positioning the first panel adjacent to the second panel on the first support.

6. The method of claim 5 , wherein the at least one support also comprising a second support, the method also comprising:
mounting the second support on the wall;
press-fitting a first projection of the at least one projection of the second support into a second opening of the at least one opening of the rear face of the second panel;
press-fitting the first projection of the at least one projection of the second support into a third opening of the at least one opening of the rear face of the first panel.

7. The method of claim 6 , wherein the press-fitting of the first projection of the first support and the press-fitting of the first projection of the second support are performed without use of any mechanical tools.

8. The method of claim 6 , wherein each of the first opening of rear face of the first panel, the first opening of the rear face of the second panel, the third opening of the rear face of the first panel, and the second opening of the rear face of the second panel has a mouth and an inner aperture in communication with the mouth that is wider than the mouth,
the first panel and the second panel each configured to resiliently deform to accommodate the press-fit by the cork resiliently compressing to receive the distal portion of the first projection of the first support and the distal portion of the first projection of the second support and resiliently act on the first projection of the first support and the first projection of the second support to retain the first projection of the first support and the first projection of the second support.

9. A method of forming a noise reduction apparatus for mounting adjacent to or above a work space, comprising:
molding cork granules in a mold to form a first panel the first panel having a front face comprised of cork and a rear face opposite the front face, the rear face comprised of cork, the rear face having at least one opening define therein;
molding cork granules in a mold to form a second panel, the second panel having a front face comprised of cork and a rear face opposite the front face, the rear face of the second panel comprised of cork, the rear face of the second panel having at least one opening define therein;
providing a first support so that the first support is extruded to have a base portion that is generally rectangular in shape, the base portion having a flat surface and the first support also having at least one projection that is elongated and extends linearly on the base portion along a length of the first support, the at least one projection also extending away from the flat surface, the at least one projection being sized to be press-fit within the at least one opening formed in the rear face of the first panel and also sized to be press-fit within the at least one opening formed in the rear face of the second panel, wherein the first support has a first projection of the at least one projection and a second projection of the at least one projection that extends from the base portion, the second projection extending away from the flat surface to a distal portion, the first projection extending farther away from the flat surface than the second projection, and wherein the first projection has a distal portion and an intermediate portion that is between the distal portion and the base portion, the distal portion of the first projection being wider or bigger than the intermediate portion;
press-fitting the first projection of the at least one projection into a first opening of the at least one opening of the rear face of the first panel via the cork of the rear face resiliently deforming to accommodate the press-fitting of the first projection within the first opening for direct attachment of the first support to the first panel;
press-fitting the first projection of the a
