Description

Technical field of the invention

The present invention relates to ceiling systems.

Background of the invention

When designing houses, whether it is a special designed or a standard house, the architect often chooses a ceiling of plaster or wood profiles. Wood strip ceilings are beautiful and very architectural. Despite this, they are not used to a large degree. This is primarily because it is a solution, which is quite difficult to mount, and thus quite costly in terms of labor.
It is therefore desirable to provide an easy-to-mount ceiling system for wood strip ceilings.

The term "sheet" as used in this application means a body whose thickness is only small in relation to its length and width. The term "sheet surface" is meant as the two outer faces of the sheet that are perpendicular to the direction of the sheet thickness. The term "sheet side edge" is meant as the remaining faces of the sheet. Preferably, the sheet side edges (three or more, depending on the form) are parallel to the direction of the sheet thickness.
The principles behind such a system is to plate an existing wall and/or ceiling of a room with one or more sheets, preferably foam sheets or sheets made from a cement-bonded wood wool. Subsequently, strips are fastened into the longitudinal grooves, preferably by the aid of spring clips. Thereby, the overall appearance of the strip ceiling is not disturbed by visible screw heads from screws used to fasten the strips to the existing wall and/or ceiling of a room. Furthermore, the use of a sheet according to the present invention obviates the need to paint or plaster the existing ceiling before fastening a strip ceiling.
Preferably, the system comprises a plurality of sheets for easier handling and mounting.
The individual sheet has opposed first and second surface sides as evident from normal plates or sheets.
The individual elongate strip has first and second spaced ends, spaced lengthwise of the elongate strip. The remaining face of the strip is the side face.
Preferably, the elongate strip is an elongate wood strip.
In one or more embodiments, an individual strip is sized and configured for releasable fastening into an individual spring clip positioned within a longitudinal groove.
Preferably, the sheets have four sheet side edges such that the sheet is squared for easier mounting and assembling. However, the sheets may e.g. also be of triangular or pentagonal form, thereby having three or five sheet side edges respectively.
In one or more embodiments, a part of the side face of an individual strip is sized and configured for releasable fastening into an individual longitudinal groove and preferably, the spring clips positioned therein, in the first sheet surface side of the sheet. This may be an advantage, if a strip needs replacement or to be cleaned or painted. This function is inherent for embodiments, where the sheet material is compressible and automatically retains its original shape. A "conformable, compressible" material is a material that readily deforms when subjected to an applied stress, but will tend to elastically recover when the stress is removed. In one or more embodiments, the sheet material is conformable, compressible.
In one or more embodiments, the system comprises a plurality of sheets; wherein the sheet side edges of the individual sheet are configured as a part of a joint for joining abutting sheets together. This is an advantage when mounting the ceiling system.
In one or more embodiments, the system comprises a plurality of sheets; wherein a sheet side edge of a first sheet comprises an elongate recess formed in and defined by the sheet material, and wherein a sheet side edge of a second sheet comprises a tongue formed in and defined by the foam sheet material; wherein the tongue engages in the elongate recess in the joined state.
In one or more embodiments, the individual longitudinal groove has a C-shaped transverse cross-section.
In one or more embodiments, the individual longitudinal groove has a transverse cross-section that is substantially circular.
In one or more embodiments, the individual longitudinal groove has a U-shaped transverse cross-section.
In one or more embodiments, a part of the individual longitudinal groove wall is configured as a tongue.
In one or more embodiments, a part of the side face of an individual strip is configured as a protrusion comprising an elongate recess extending along the length of the strip; and wherein a part of the individual longitudinal groove wall is configured as a tongue; wherein the tongue engages in the elongate recess in the joined state.
In one or more embodiments, the sheet is made from a foam material, such as an open or closed cell material selected from the group consisting of melamine-resin foam, polyurethane foam, polystyrene foam, inorganic foam, silicone foam, and mixtures thereof.
In one or more embodiments, the sheet is made from a cement-bonded wood wool, such as Troldtekt®. This material is particularly preferred for its sound dampening/absorbing effect on sound waves.
In one or more embodiments, the system further comprises fastening means for attaching the sheet to an existing wall and/or ceiling of a room. The spring clip may be configured with a channel for receiving such fastening means. The spring clip will thereby be further fixed within the individual longitudinal groove, such that the strip can be released therefrom without risk of damaging the sheet.
Another aspect relates to a sheet for a strip ceiling system, the sheet having opposed first and second sheet surface sides, and at least three sheet side edges; wherein a plurality of parallel longitudinal grooves are formed in the first sheet surface side of the sheet.
In one or more embodiments, one or more sheet side edges comprises an elongate recess formed in and defined by the sheet material and/or a tongue formed in and defined by the sheet material.
Another aspect relates to the use of a sheet for building a strip ceiling, the sheet having opposed first and second sheet surface sides, and at least three sheet side edges; wherein a plurality of parallel longitudinal grooves are formed in the first sheet surface side of the sheet.
