DESCRIPTION:
BRIEF SUMMARY
The invention relates to service access arrangements for flooring systems having provision below their floor surface for taking services including electrical power, communications etc.
Copending patent application No. 8507914 (P1466) concerns such a flooring system that has particular application as a so-called suspended floor, such as added-on to an existing floor as a base or substrate during refurbishing buildings, and to segregation of services. As described in that application segregation ducting is usually provided in sections capable of fitting end-to-end, and further in spaced parallel relation over broad floors. Such segregation ducting actually isolates electric power service feeds in a highly satisfactory manner, and further allows safe feeding sideways into trunking extending away from the ducting for other services to run segregated within and to one or both sides of the trunking. Such trunking, including dividers for spaces between the trunking in three- or more-way segregation, serve directly in supporting panels of the new floor.
It will be evident that access will be required to the services in and/or alongside such trunking, often along its length. It is convenient to do so via service access units that are left into the new floor, and especially advantageous utilising units embodying this invention.
According to this invention, a service access unit is provided in, or for letting into, a floor system having elongate trunking for one service feed segregated from other service feed or feeds, the unit comprising a frame to extend across such trunking and beyond such trunking at least to one side thereof, the frame being securable relative to an aperture in the floor of greater size than a lesser aperture into the top of said trunking, said lesser aperture to be within the first-mentioned aperture; and a subsidiary member fitting within the frame with securement means thereto, such member then extending into said lesser aperture and affording outlet for the service in the trunking, outlet for at least one other service whose feed is outside the trunking then being available from at least one side of the subsidiary member but within the frame.
The subsidiary member may be of flanged channel section with its channel sides closing off upper section portions of the trunking to define, conveniently in further cooperation with upper side portions of the trunking, a box inset into the trunking at said lesser aperture. Service is readily taken from said outlet or outlets of said inlet inset box with is segregation from other services maintained, e.g. as is often required for electric power feed. Within the frame, however, further provision can be made for other services to be taken out from one or both sides of the subsidiary member.
Conveniently, a top closure for the aforesaid frame has exit provision for service take-offs and is above the aforesaid trunking at installation. That exit provision can be via cut-outs from confronting edges of top flaps hinged to the frame. Other services accessible to a side or sides of the trunking can have outfeeds via the same exit provision, usually from a suitable further member or members spaced from said subsidiary member and affording outlet location in allowing connections to said other services segregated from the trunked service, usually also from each other insofar as coming from different sides of the trunking and first-mentioned subsidiary member.
A particularly advantageous aspect of access units hereof concerns their top closures as especially related to hinging of at least one part of a top closure to the associated frame via multiple pivotted links that allow such top part to be raised bodily from the frame as well as swing like a hinge, preferably so that the top part can stand upright with its end tucked between link pivots to the frame and the frame itself, but alternatively simply displaced bodily sideways from its closed position. Normally, the links will not go to or over centre in clearing the adjacent side of the frame. A frame with a top as
