Abstract
Abstract In an access floor construction, service outlets (7), such as electrical sockets, are connected to a service supply accommodated in the underfloor space (5) by leads (9) extending through openings (8) in the edges of some of the removable panels which form the access floor. The removable panels with such openings can be interchanged with other panels and oriented so as to locate an opening (8) in a position close to a service outlet so as to permit the lead from the outlet to pass conveniently into the underfloor space (5) for connection to the service supply.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
122 words
An access floor construction having an access floor formed from removable panels supported on a subfloor to form an underfloor space accommodating at least one service supply which includes at least one distribution device disposed in the underfloor space, at least one of the removable panels forming the access floor having at least one access opening in at least one edge thereof, characterized by at least one service outlet disposed above floor level and having at least one associated lead connected to an adjacent distribution device in the underfloor space via said at least one access opening, the said at least one lead of the service outlet being encased in trunking from the service outlet to said at least one access opening.
Claim 2
Dependent Claim
122 words
An access floor construction having an access floor formed from removable panels supported on a subfloor to form an underfloor space accommodating at least one service supply which includes at least one distribution device disposed in the underfloor space, at least one of the removable panels forming the access floor having at least one access opening in at least one edge thereof, characterized by at least one service outlet disposed above floor level and having at least one associated lead connected to an adjacent distribution device in the underfloor space via said at least one access opening, the said at least one lead of the service outlet being encased in trunking from the service outlet to said at least one access opening.
Claim 3
Dependent Claim
66 words
An access floor construction as claimed in claim 1, characterized in that the service outlet comprises at least one electrical outlet and at least one telecommunication outlet and the trunking includes means separating a telecommunication lead associated with said at least one telecommunication outlet from an electrical lead associated with said at least one electrical outlet and electrically shielding said telecommunication lead from said electrical lead.
Claim 4
Dependent Claim
30 words
An access floor construction as claimed in claim 1, characterized in that said at least one lead is connectable to the distribution device by means of plug and socket connectors.
Claim 5
Dependent Claim
85 words
An access floor construction as claimed in claim 1, characterized in that said at least one service supply includes a plurality of said distribution devices disposed throughout the underfloor space, preferably, in a regular array, and a plurality of said floor panels having said access openings in their edges are distributed throughout the access floor, whereby to permit the associated leads of a plurality of said service outlets disposed above floor level at spaced locations to be connected to adjacent ones of said distribution devices.
Claim 6
Dependent Claim
29 words
An access floor construction as claimed in claim 4, characterized in that unused ones of said access openings in the floor panels are closed by means of suitable plugs.
