Abstract
Abstract A vinyl ceiling grid structure for supporting ceiling panels comprising a two-way connecting member, a one-way connecting member, an angled slat, an inner angled plate, an outer angled plate and a receiving base. Each of these components is formed integrally with plastics and can be selectively assembled together to form a grid system. The one-way and the two way connecting members are provided for the connection of the partitioning board to form the grid structure suspended in the ceiling. The angled plates can either be selected from the inner type or the outer type depending on the application. The receiving base is inserted at the end of the partitioning board so as to be able to connect to the angled slat, forming the vinyl ceiling grid structure for supporting the ceiling panels.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
82 words
A vinyl ceiling grid structure comprising: a first connecting member for connecting at least two partitioning boards, the first connecting members having a generally planar base with opposite sides and a plurality of first insert-to-fit plates located in a plane extending generally perpendicular to the base, the first insert-to-fit plates having distal ends extending towards opposite sides of the base, and a convex pipe section on an upper portion of the insert-to-fit plates extending in the plane of the first insert-to-fit plates.
Claim 2
Dependent Claim
82 words
A vinyl ceiling grid structure comprising: a first connecting member for connecting at least two partitioning boards, the first connecting members having a generally planar base with opposite sides and a plurality of first insert-to-fit plates located in a plane extending generally perpendicular to the base, the first insert-to-fit plates having distal ends extending towards opposite sides of the base, and a convex pipe section on an upper portion of the insert-to-fit plates extending in the plane of the first insert-to-fit plates.
Claim 3
Dependent Claim
33 words
The vinyl ceiling grid of claim 1 further comprising at least one partitioning board having a hollow chamber receiving an insert-to-fit plate so as to connect the partitioning board to the connecting member.
Claim 4
Dependent Claim
17 words
The vinyl ceiling grid of claim 2 wherein the partitioning board has an inverted "T" cross-sectional configuration.
Claim 5
Dependent Claim
42 words
The vinyl ceiling grid of claim 1 further comprising a second connecting member having second insert-to-fit plates and a concavely curved latching portion engaging the convex pipe section such that the second insert-to-fit plates extend generally perpendicular to the first insert-to-fit plates.
Claim 6
Dependent Claim
14 words
The vinyl ceiling grid of claim 1 wherein the base has a cruciform configuration.
Claim 7
Dependent Claim
62 words
The vinyl ceiling grid of claim 1 further comprising: a) at least one partitioning board having opposite ends each with a hollow chamber, a first opposite end engaged with the first insert-to-fit plates; b) at least one angled slat; and, c) a receiving base attached to the at least one angled slat and engaging the second opposite end of the partitioning board.
Claim 8
Dependent Claim
46 words
The vinyl ceiling grid of claim 6 wherein the receiving base comprises: a connecting support board; a third insert-to-fit plate configured to engage the hollow chamber of the at least one partitioning board; and a latching plate configured to engage the at least one angled slat.
Claim 9
Dependent Claim
49 words
The vinyl ceiling grid of claim 6 further comprising: a pair of angled slats, each having hollow chambers; and an angled plate having a plurality of connecting plates thereon configured to engage the hollow chambers of the pair of angled slats so as to connect the angled slats together.
Claim 10
Dependent Claim
31 words
The vinyl ceiling grid of claim 8 wherein the connecting plates define an angle therebetween of approximately 90° such that the pair of angled slats extend approximately 90° to each other.
Claim 11
Dependent Claim
21 words
The vinyl ceiling grid of claim 6 wherein the at least one angled slat has a substantially "L" shaped cross-sectional configuration.
