Abstract
A suspended ceiling assembly is provided with its metallic runners covered with magnetic articles, which may be discrete or continuous members. The magnetic articles comprise an outer facing layer and an inner magnetic layer, and are conformed to fit over and embellish the runners. Preferably, the outer facing layer comprises a plastic material and the inner magnetic layer comprises a ferromagnetic material and a binder.
Claims14
A suspended ceiling assembly which comprises a network of parallel extending metallic main runners and parallel extending metallic cross runners, the main and cross runners intersecting and being arranged in a geometric pattern to form a series of rectangular openings for ceiling panels, each of the runners having a cross-sectional, inverted T-shape with a vertical web and a horizontal flange extending to either side of the vertical web, and each of the runners having the normally exposed lower surface of its horizontal flanges covered by an elongated magnetic strip, each of which strips (a) being flexible and having a width and length which match the width and length of the exposed lower surface of the flanges being covered, the flexibility of each strip being sufficient so that the strip can be unwound from a roll for easy application to the flanges, and (b) comprising an outer facing layer and an inner magnetic layer.
A process of retrofitting a suspended ceiling structure which has a network of parallel extending metallic main runners and parallel extending metallic cross runners, the main and cross runners intersecting and being arranged in a geometric pattern to form a series of rectangular openings for ceiling panels, each of the runners having a cross-sectional, inverted T-shape with a vertical web and a horizontal flange extending to either side of the vertical web, the process comprising
- (a) providing an elongated magnetic strip in roll form for application to the horizontal flanges of the runners, the strip comprising an outer facing layer and an inner magnetic layer,
- (b) unwinding the strip from the roll, the strip being sufficiently flexible so that it can be unrolled for easy application, and
- (c) contacting the normally exposed lower surface of the horizontal flanges of each of the runners with the inner magnetic layer of the strip, the strip having a width and length which match the width and length of the exposed lower surface of the flanges being contacted,
- whereby the inner magnetic layer of the strip becomes magnetically attached upon contact to the lower surface of the horizontal flanges of the metallic runners.
