- 7 Referring to the drawings there is illustrated a floor box according to the invention indicated generally by the reference numeral 1. The floor box 1 comprises a collar 2 for mounting in an opening in a floor 3, and a lower housing 4 having knock-out inlets 5 for cables 6 and sockets such as telephone sockets 10, computer sockets 11, power supply sockets 12 and the like. The box is segmented to allow typically at least four separate mounting plates for equipment to be accommodated. The floor box 1 also includes an upper door assembly comprising a door frame 15 and door 16 having cable outlets 17 through which outlet cables 18 connected to the sockets 10, 11, 12 are led. Cables which have already been terminated may be brought into the base by removing gland plates. Cord grips may be provided.
In this case the lower housing 4 is releasably mounted to the collar 2. As will be particularly apparent from Figs. 6 to 8, the lower housing 4 and collar 2 have releasable engagement means for engaging one with the other. The releasable engagement means comprises a male lug part 20 extending inwardly from the collar side wall 4 for releasable engagement with a female part in the form of a slot 21 in the housing part. The slot 21 is defined by a rod 22 of spring material which is self retained in position and is mounted and shaped as indicated in Fig. 6 to define the slot 21 for engagement with the lug 20 for mounting the lower housing 4 to the collar 2 as illustrated particularly in Fig. 6. Indented stops 19
IE 90309
- 8 are provided on the collar 2 to limit the upward travel of the lower housing 4 when engaging the lugs 20. Access means for releasing the spring 22 from engagement with the lug 20 is, in this case, provided by a downwardly extending slot 25 in the housing 4 through which a tool such as a screw driver may be inserted to release the spring 22 from engagement with the lug 20 and allow the lower housing 4 to be disengaged from the collar 2. In this case there are two releasable engagement means, one at either end of the lower housing and collar, however, it will be appreciated that a suitable number of engagement means may be employed for mounting the lower housing to the collar.
The collar includes two sidewardly extending flanges 25 for mounting the collar 2 to a floor 3 as illustrated in Fig. 13, the collar being inserted into the opening in the floor from below and being fixed in position by fixing screws inserted through flanges 27 in the collar. When the collar is fixed in position, the lower housing 4 with the cable 6 and sockets 10, 11, 12 in position and wired up is then pushed from below into the collar 2 until the lugs 20 are engaged with the springs 22. If it is desired to remove the housing 4, for example, for access for wiring further sockets or a screw driver or similar tool is inserted into the access slots 25, releasing the springs 22 and allowing the lower housing 4 to be disengaged from the collar 2.

- 9 Referring particularly to Figs. 9 to 13, it will be noted that the door 16 is moved from a closed position in which it lies substantially flush with the frame 15 to an open position in which the door is swung substantially 180° out of the frame 15.
Hinge means, in this case provided by two-spaced apart hinges are provided between the door 16 and the surrounding frame 15. Each hinge means comprises a first hinge part 30 which is hingedly mounted to the frame 15 and a second hinge part 31 which is hingedly mounted to the door 16. The first and second hinge parts 30, 31 are pivotally interconnected by a hinge pin 35 for pivotal movement of the door out of the door frame 15 and for pivotal movement of the door 16 through substantially 180° as will be particularly apparent from Figs. 12(a) and 12(b). It will be noted that the door frame 15 includes an inwardly extending flange 37 for mounting the first hinge part 30 to the frame 15 and for mounting the door frame 15 to a similar inwardly extending flange 38 provided on the lower housing 4 as will be particularly apparent from Fig.
.
The door frame 15 includes an outer flange 50 for engagement with the floor covering or the like. Stop means 55 are provided on the door frame 15 to limit the movement or the door 16 into the frame 15. The outer flange 50 also acts as a stop to limit the opening of the centre points of the hinges. Similarly, the hinge parts are slightly cranked in the region of the centre pin to ensure the hinges are always
IE 90309
- 10 tending to close when open, thus preventing unnecessary hinge extension and making closure easy.
Referring particularly to Figs. 9, 10 and 14 to 16, in this case there are three cable outlet slots 17, each having a closure member 40 which is pivotally movable relative to the door 16 from an open position illustrated in Figs. 14 and 16 in which the outlet cables 18 pass through the slots to a closed position in which the closure members 40 are substantially flush with the door as illustrated in Fig. 15.
The closure members 40 are pivotally mounted in an outlet cable closure housing 45 which is in turn mounted to the door
16. The closures 40 and closure housing 45 are provided with slots 46 and associated ledges 47 respectively for snapfittingly engaging the closure members 40 in the closed position.
The housing 45 includes an indent 60 having a recessed handle 61. The indent 60 has a lead-in portion for lifting the handle 61 to the raised position illustrated in Fig. 14.
Each closure flap 40 is held captive between the housing 45 and the door 16 when the housing 45 is fixed to the lid by fixing screws 65. The door 16 is of tray formed sheet steel construction having shaped notches cut in the edge opposite the hinged edge. The notches accommodate the housing 45 which is retained in place on the door 16 by means of the fixing
IE 90309
- 11 screws 65 which pass through the door 16 and into brass inserts moulded into the plastics closure flap housing 45. The hinging of the closure flap 40 is accomplished by moving pivot points formed at each end of the closure flap 40 and housing 45. A tongue 66 on the door 16 acts as a sliding pivot support surface extending the length of the closure flap
40.
The opening of the closure flap 40 is constrained by housing triangular pivot points 67 at each end of the closure flap 40 in complementary triangular sockets 68 in the housing 45. Triangular stops 69 are also provided which engage when the closure flap 40 is opened on the underside of the tongue 66 of the door 16.
Many variations of a specific embodiment of the invention may be readily apparent and accordingly the invention is not limited to the embodiments hereinbefore described which may be varied in both construction and detail.
