Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
209 words
A portable space divider screen which comprises a panel having a head and bottom rails joined by end rails to form a perimeter frame, and an intermediate rail joined to infill means between the head rail and intermediate rail and means to join a said panel to other panels comprising pairs of sockets in at least the top rail of the panel to receive pins on connectors adapted to interconnect two panels, a septum between the said head and intermediate rails extending to said end rails, said infill means being over said septum and comprising multiple cellular members on each side of said septum with the cells containing sound absorbent material, perforated wall members enclosing the said infill means on both sides of the said panel, covers of sound absorbing fabric over the said perforated wall members, a longitudinal slot at the upper face of the upper rail and a longitudinal slot at the lower face of the bottom rail, ducts to contain electrical wiring longitudinally extending along between the bottom rail and the intermediate rail of the said panel, and skirtings also longitudinally extending along the lower portions of the said panel and disposed to cover the said ducts and adapted to support electrical switching and power outlets.
Claim 2
Dependent Claim
209 words
A portable space divider screen which comprises a panel having a head and bottom rails joined by end rails to form a perimeter frame, and an intermediate rail joined to infill means between the head rail and intermediate rail and means to join a said panel to other panels comprising pairs of sockets in at least the top rail of the panel to receive pins on connectors adapted to interconnect two panels, a septum between the said head and intermediate rails extending to said end rails, said infill means being over said septum and comprising multiple cellular members on each side of said septum with the cells containing sound absorbent material, perforated wall members enclosing the said infill means on both sides of the said panel, covers of sound absorbing fabric over the said perforated wall members, a longitudinal slot at the upper face of the upper rail and a longitudinal slot at the lower face of the bottom rail, ducts to contain electrical wiring longitudinally extending along between the bottom rail and the intermediate rail of the said panel, and skirtings also longitudinally extending along the lower portions of the said panel and disposed to cover the said ducts and adapted to support electrical switching and power outlets.
Claim 3
Dependent Claim
48 words
A portable space divider screen according to claim 1 characterised in that the said cellular members are spaced on each side of the said septum with the septum disposed centrally in the said panel, said septum forming a back to close the said cells of said cellular members.
Claim 4
Dependent Claim
165 words
A portable space divider screen comprising a head rail and a bottom rail joined by end rails extending to and to form a perimeter frame and including a rail intermediate the head and bottom rails, a septum extending between the top rail and the intermediate rail and joined to the end rails, multiple cellular members extending over the said septum on each side thereof with the cells filled with a sound-absorbing material, each of said cellular members having an outer face, acoustic perforated wall members extending over the outer faces of the said cellular members and having sound-absorbing fabric extending over the outer surface thereof, apertures in at least the top face of the head rail arranged in multiples, and adapted to be engaged by pins on joining connectors to join two divider screens together, a service duct formed between the said bottom rail and the said intermediate rail, and a removable skirting member closing the said service duct on at least one face thereof.
Claim 5
Dependent Claim
165 words
A portable space divider screen comprising a head rail and a bottom rail joined by end rails extending to and to form a perimeter frame and including a rail intermediate the head and bottom rails, a septum extending between the top rail and the intermediate rail and joined to the end rails, multiple cellular members extending over the said septum on each side thereof with the cells filled with a sound-absorbing material, each of said cellular members having an outer face, acoustic perforated wall members extending over the outer faces of the said cellular members and having sound-absorbing fabric extending over the outer surface thereof, apertures in at least the top face of the head rail arranged in multiples, and adapted to be engaged by pins on joining connectors to join two divider screens together, a service duct formed between the said bottom rail and the said intermediate rail, and a removable skirting member closing the said service duct on at least one face thereof.
Claim 6
Dependent Claim
30 words
A portable space divider according to claim 3 including a longitudinal slot in the lower face of the lower rail adapted to be engaged by brackets adapted to carry shelves.
Claim 7
Dependent Claim
43 words
A portable space divider screen according to claim 3 characterised by a longitudinal slot in the top face of the panel and a longitudinal slot in the lower face of the lower rail adapted to be engaged by brackets adapted to carry shelves.
Claim 8
Dependent Claim
67 words
A portable space divider according to claim 5 wherein the space divider has outer faces and including shelves attached to brackets extending down the outer faces of the said space divider, the said brackets being shaped to have an upper portion extend over the top of the said upper rail and down to engage in the said longitudinal slot in the top face of the upper rail.
Claim 9
Dependent Claim
19 words
A portable space divider screen according to claim 6 characterised in that the said sound-absorbing fabric is wool cloth.
Claim 10
Dependent Claim
63 words
A portable space divider screen according to claim 6 wherein the upper rail has a top and is characterised by a pair of strips longitudinally extending across the top of the said upper rail said strips being spaced apart and joined to the head rail to form part thereof and to form between them the said longitudinal slot in the said head rail.
Claim 11
Dependent Claim
53 words
A portable space divider according to claim 8 characterised by reinforcing members extending across and down both sides of the said strips at the upper rail to line the said longitudinal slot and extend down beyond the outer faces of the strips to cover the outer edge portions of the said upper rail.
