Benefits of technology

"The present invention provides a suspended ceiling grid system that can be easily assembled or disassembled without damaging the main grid members and cross members permitting them to be reused. The invention includes a longitudinal connection for abutting ends of main grid members and a linear connection for connecting cross members to the main grid members. These connections allow for easy assembly and disassembly of the suspended ceiling system."

Problems solved by technology

While the connection is intended to be disengaged when required the pockets must be opened first which is not easy to do.

Embodiment Construction

[0027]Referring now to the figures in detail, FIG. 1 illustrates a longitudinal connection according to the present invention between the abutting ends of one main grid member, generally indicated at 11 and a second main grid member, generally indicated at 12. In the embodiment illustrated both main grid members 11, 12 each have an inverted T cross section having a web portion 13, 14 with a horizontal flange 15, 16 extending perpendicular from the base of the web portion 13, 14. While the embodiment illustrated in the Figures shows the present invention used in association with main grid members having an inverted T cross-section, it should be appreciated that the present invention is applicable to other shapes of main grid members. The grid members 11, 12 may be made of conventional materials and formed by conventional techniques or may be made by extrusion molding aluminum or zinc or other suitable material.

Abstract

A longitudinal connection for abutting ends of main grid members of a suspended ceiling system is provided where each, of the main grid members have a vertical web portion and a horizontal flange extending across a bottom of the web portion. The longitudinal connection comprising retaining means on the web portion of each of the main grid members adjacent the abutting ends providing an upper and a lower channel. A plate member having opposite first and second sides is slidable within the upper and lower channels on the ends of each of said main grid members. Moveable pin members are provided on the plate member where the pin members are biased to the web portion of the main grid members. Holes on the retaining means on the web portion of each of the main grid members adjacent the abutting ends providing an upper and a lower channel are positioned to receive the pin members when the abutting ends of main grid members are aligned. This results in the plate member pulling the main grid members together at the abutting ends.

Description

FIELD OF THE INVENTION[0001]The present invention relates to suspended ceiling systems and in particular improved connections for end to end connection of the main grid members of such systems and for connection of cross members to the main grid members.BACKGROUND OF THE INVENTION[0002]Suspended ceiling systems are well known and are commonly used to conceal piping, wiring or ductwork beneath the overhead structure. The suspended ceiling grid system comprises wall angle mouldings, main grid members (main tees) running in one direction of the ceiling with cross members (cross tees) connected to adjacent grid members to form the grid pattern. The most common grid patterns are rectilinear or square grids although non-rectilinear patterns can be used. Each grid defined by the main grid members and cross members is typically filled with a lightweight acoustic ceiling tile or panel which is suspended within the grid.[0003]The main grid members or tees are suspended from the floor above by...
