Abstract
Abstract Disclosed is a suspended ceiling having rectilinear panels held within a co-planar matrix of inverted T-grid elements; each T-grid element possesses a horizontal and a vertical component. The T-grid elements are suspended by their vertical component from the natural ceiling or ceiling beams. The improvement set forth relates the use of imitation beams secureable to the horizontal components of the matrix of T-grid elements at a time after installation of the suspended ceiling has occurred. Each of the imitation beams is an elongate rectilinear element complemental on at least one surface with the horizontal component of the T-grid elements. Included are press-fit securement elements in the rectilinear elements, such elements imbedded within the complemental surface of the elongate elements. Thereby an imitation beam structure for a suspended ceiling may be achieved through the manual affixation of the rectilinear elements to the horizontal components of the matrix of the T-grid elements. Each of the rectilinear elements is provided with a woodgrain or other pleasing-to-the-eye surface ornamentation such that, from the perspective of an occupant of a room covered by a suspended ceiling, a favorable impression of depth and richness is imparted.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
164 words
A suspended ceiling having a multiplicity of rectilinear panels held within a co-planar matrix of inverted T-grid elements having horizontal and vertical components, each vertical component suspended from a natural ceiling, the improvement comprising: a plurality of imitation beams secureable to said horizontal component of said inverted T-grid elements after installation of said suspended ceiling has occurred, each of said imitation beams themselves comrising: (a) an elongate rectilinear element complemental on at least one surface with said horizontal component of said T-grid elements, said one surface of said horizontal component comprising a ferro-magnetic material; and (b) means for effecting a press-fit securement of said elongate element to said horizontal component of said T-grid element, said press-fit means imbedded within said complemental surface of said elongate rectilinear element said press-fit means comprising a permanent magnet, whereby an imitation beam structure for a suspended ceiling may be achieved through the affixation of said rectilinear elements to said horizontal components of said matrix of inverted T-grid elements.

A suspended ceiling having a multiplicity of rectilinear panels held within a co-planar matrix of inverted T-grid elements having horizontal and vertical components, each vertical component suspended from a natural ceiling, the improvement comprising: a plurality of imitation beams secureable to said horizontal component of said inverted T-grid elements after installation of said suspended ceiling has occurred, each of said imitation beams themselves comrising: (a) an elongate rectilinear element complemental on at least one surface with said horizontal component of said T-grid elements, said one surface of said horizontal component comprising a ferro-magnetic material; and (b) means for effecting a press-fit securement of said elongate element to said horizontal component of said T-grid element, said press-fit means imbedded within said complemental surface of said elongate rectilinear element said press-fit means comprising a permanent magnet, whereby an imitation beam structure for a suspended ceiling may be achieved through the affixation of said rectilinear elements to said horizontal components of said matrix of inverted T-grid elements.
Claim 3
Independent Claim
159 words
A method for providing a suspended ceiling having a multiplicity of rectilinear panels within a co-planar matrix of inverted T-grid elements, said elements having horizontal and vertical components, said vertical components suspended from the natural ceiling, with a multiplicity of imitation beams, the method comprising the steps of: (a) providing a plurality of elongate rectilinear elements complemental on at least one surface with said horizontal components of said inverted T-grid elements said one surface of said horizontal components comprising a ferro-magnetic material; (b) providing said complemental surface of each of said elongate rectilinear elements with means for effecting a press-fit securement of said elongate elements, said means for effecting a press-fit comprising a permanent magnet to said horizontal component of said T-grid elements; and (c) manually pressing said elongate elements onto said horizontal components, whereby an imitation beam structure may be achieved through the affixation of said rectilinear elements to said horizontal components of said matrix of T-grid elements.
