Foldable and flexible laminated mat

Abstract

A chair pad or a roll up mat that can be manufactured from medium density fiberboard with a laminate surface decorative layer applied thereon. The laminate is treated with various protective coatings, to add resistance to natural deleterious factors including water and dirt. The chair mat includes a series of planks, held together by tape, with an under layer of a mesh, all applied by resin together, and having a bottom layer of a felt or rubber to provide cushioning when the mat is applied upon a floor or surface, and to function as a living hinge, when it is rolled up or folded for storage or shipment.

AI Technical Summary

Benefits of technology

[0009]There are various types of MDF / laminate flooring including tongue and groove type, and the type that needs to be butted together. The lacquered flooring panels are finished using wear resistant UV lacquer and the unlacquered flooring panels need to be coated / waxed and polished after installation. The strength of MDF / laminate boards can be better than common wood boards due to the high pressure and high temperature of their manufacturing process.

[0014]During the assembly process, a mesh sheet is placed on the bottom side of the chair mat. The mesh sheet can be made of nylon fibers, or other polymers. A mastic layer is then placed over the nylon mesh sheet, thereby adhering it to the undersurface of the aligned planks, and then a final layer of high density felt or sisal can be applied under the mesh sheet. Such a high density layer can be preferably of about approximately 2 mm in thickness. The chair mats can then be cut to the desired dimensions. This bottom high density layer can be made of the matted felt, rubber, or polymer padding, bonding over and to the resin material layer, and this layer can function as a type of living hinge, for the aligned slats, when they are rolled up, or folded into closures when used as a chair pad, thereby eliminating the need for usage of any metal hardware, for hinge purposes, in the construction, manufacture, and usage of this current invention.

[0016]A further object of this invention is to provide for the use of lower cost materials in the fabrication of a high strength chair mat or pad, when employed for those purposes.

Problems solved by technology

Hardwood chair mats, however, are not flexible, are very expensive, and do tend to crush down on any underlying rugs, due to their weight.

Such chair mats, particularly the larger ones, are difficult to move about and very difficult to ship because of the special packaging required.

Obviously, cost can be an excessive factor.
