Definitions

  • the invention relates to suspended false ceilings or firewalls, and to the mounting of access panels as part of the false ceiling or firewall structure, to allow access to the void space immediately above the false ceiling or immediately behind the firewall.
  • the invention provides a novel hinge arrangement for mounting such access panels, and to the access panels when so mounted.
  • a suspended false ceiling typically comprises a metal framework suspended beneath the true ceiling, with ceiling panels supported by that framework to present a uniform and level ceiling appearance when viewed from the room below. Access is almost invariably required to the void space above the suspended ceiling, where the main service utilities such as electric cables, water pipes and air ducts are located.
  • the access panels are generally pivotally mounted to the false ceiling framework, and can be lowered to permit access to the void space above the false ceiling.
  • there is generally a void area behind the firewall where the main service utilities are provided, and access openings are needed to permit access to those utilities.
  • the hinge is a simple continuous piano hinge aligned with its hinge axis in the plane of the bottom of the ceiling or in the plane of the exposed face of the firewall, so that as the access panel is opened it pivots around its bottom corner.
  • Such a hinge arrangement is cheap and reliable, but does have the very severe disadvantage that the edge of the hinge is always clearly visible from the room, as a hinge line projecting from the exposed face of the false ceiling or firewall. This is regarded as extremely undesirable, since architects and end users prefer a finished suspended ceiling or firewall which has a completely uniform appearance, with the access panels being as far as possible indistinguishable from the remainder of the suspended ceiling or firewall. Many efforts have been made, therefore, to recess the pivotal axis of the false ceiling or firewall access panel until it is no longer visible from the room. This involves a more complex movement of the access panel than simple pivotal movement as it is opened and closed.
  • the invention provides an access panel for allowing access to a void space beyond a false ceiling or firewall, comprising a front face which in use lies flush with the exposed face of the false ceiling or firewall and a rear face displaced from the front face by the thickness of the access panel; and a mounting assembly for mounting the access panel on the false ceiling or firewall for pivotal movement generally about a pair of pins extending from opposite sides of the access panel and adjacent a pivoting edge portion thereof, each pin traversing an associated cam guide slot in the supporting framework of the false ceiling of firewall during the pivotal opening and closing movement of the access panel; wherein the mounting assembly further comprises a double axis hinge comprising a support plate fast to or integral with the rear face of the access panel; a guide plate pivotally connected to the support plate about a first hinge axis coincident with or parallel to the rear face of the access panel; and a mounting plate pivotally connected to the guide plate about a second hinge axis spaced from and parallel to the first hinge axis, the mounting plate being provided with means for connection to an
  • the invention also provides a false ceiling or firewall access panel assembly, in which a false ceiling or firewall access panel according to the invention is mounted to the frame of a false ceiling or firewall to be movable pivotally to open or close an access opening.
  • the guide plate of the hinge assembly holds the access panel square to the frame of the access opening and forces the pins to traverse the cam guide slot to ensure that the bottom corner edge of the access panel moves in a controlled path without swinging into and fouling the corresponding edge of the frame of the access opening.
  • the guide plate may be a simple flat plate connecting the two pivotal axes of the double axis hinge, in which case the first hinge axis should be along the rear pivoting edge of the access panel.
  • the guide plate is shaped to allow the first hinge axis to be displaced inwardly from the rear pivoting edge of the access panel.
  • the shaping of the guide plate in this way makes it possible to provide a positive stop to the maximum pivotal opening movement of the access panel by inter-engagement between the guide plate and the rear surface of the access panel. Such a positive stop prevents fouling of the front face of the access panel against the supporting framework of the false ceiling or firewall by movement of the access panel beyond its intended maximum range of opening movement.
  • a suspended false ceiling indicated generally as 1 comprising an array of ceiling tiles 2 supported by a suspended grid of supporting rails 3.
  • the suspension of the grid is by any conventional means.
  • Figure 1 shows three of the ceiling tiles 2 removed, so as to permit sight of the rails 3 of the grid, and to permit sight of the void space 4 above the false ceiling.
  • FIG. 1 Also illustrated in Figure 1 is an access panel 5 for allowing access to the void space above the false ceiling.
  • the access panel 5 is shown partially open, and a double-headed arrow 6 illustrates the opening and closing movement of the access panel 5 which is a generally pivotal movement around one pivoting edge portion 7 of the access panel 5.
  • One corner of the pivotal edge portion 7 is encircled and marked A , and it is that corner which is shown in greater detail in Figures 2 to 8.
  • FIGS 2 to 8 illustrate the pivotal mounting of the access panel 5.
  • the access panel 5 comprises a metal top plate 8 which is the size of the access opening and a bottom face 9 which, when the access panel 5 is closed, lies flush with the remainder of the suspended ceiling 1. Since the terms 'top' and 'bottom' are specific to false ceilings whereas this invention is generic to false ceilings and firewalls, the metal plate 8 will hereafter be referred to as the rear plate 8, and the opposite face 9 will be referred to as the front face 9. It is the front faces of the false ceiling or firewall and of the access panel 5 which are visible from the room.
  • the front face 9 of the access panel 5 is a metal plate. It should be understood however that any suitable cladding may be supported by the access panel 5, typically one or more acoustic tiles.
  • the pivoting edge portion 7 of the access panel 5 has one exposed corner 10 which must be protected by preventing it from fouling the corresponding edge of the frame 3 of the access opening. This is achieved according to the invention by means of a double axis hinge assembly 11 in association with pins 13 received in associated cam guide slots 12 which will be described in greater detail below.
  • the double axis hinge assembly 11 comprises a support plate 14 which in use is secured to the rear face of the metal plate 8, for example by spot-welding, by bolts or by rivets.
  • the support plate 14 defines a first hinge axis 15 which in use is parallel to and in this embodiment displaced slightly inwardly from the exposed corner 10 of the pivoting edge portion 7 of the access panel 5 when the access panel 5 is in its closed condition.
  • Hinged to the support plate and thus to the top face of the access panel along that pivoting edge portion 7 is a guide plate 16 which is kinked or angled as illustrated by means of a longitudinal fold 16' parallel to the first hinge axis 15. The reason for this shaping of the guide plate 16 will become apparent later.
  • the longitudinal edge of the guide plate 16 remote from the first hinge axis 15 defines a second hinge axis 17 spaced from and parallel to the first hinge axis 15.
  • a mounting plate 18 is hinged to the guide plate 16 about the second hinge axis 17.
  • the mounting plate 18 is secured fast to the supporting rail 3 which defines one edge of the access opening, for example by spot welding, by bolts or by rivets (not shown).
  • the double axis hinge 11 is preferably a continuous hinge extending substantially the entire width of the access panel 5.
  • a linear array of two or more discrete hinges 11 could be provided, spaced apart along the width of the access panel 5, provided that their respective hinge axes 15 and 17 are in mutual alignment.
  • mounting brackets 19 At opposite ends of the hinge 11 or of the array of hinges 11 are mounting brackets 19 as shown in Figure 8, each of which carries a laterally projecting pin 13 about which pivotal movement of the access panel 5 takes place during opening and closing.
  • the pins 13 are received in cam guide slots 12 formed as illustrated in the side walls 3 of the access opening or in plates (not illustrated) secured to those side walls 3.
  • the cam guide slots 12 are enclosed slots in which the pins 13 move, and the shape of the slots is variable.
  • the slots 12 are inclined downwardly in the general direction from the pivoting edge portion 7 towards the opening edge of the access panel 5 as shown, so that the weight of the access panel assists in moving the pins 13 along and down the slots 12 as the panel 5 is moved from the closed to the open condition (see Figures 2 to 7).
  • the slots 12 may be linear as shown or non-linear. What is most important about the shapes of the slots 12 is that they must extend away from the pivoting edge portion 7 of the access panel 5 and away from the exposed corner 10, so that as the panel is moved from a closed condition ( Figure 2)) to an open condition ( Figure 7) the pins 13 move laterally in the slots 12 and draw the pivoting edge portion 7 of the access panel 5 away from the corresponding edge of the access opening.
  • the front face or exposed corner 10 of the access panel 5 thus does not foul the supporting framework 3 of the false ceiling.
  • the mounting brackets 19 are retained by screws 20 received in the rear face of the access panel 5, with slots 21 allowing adjustment in the direction of the double-headed arrow B to permit assembly.
  • the double axis hinge 11 forces the pins 13 to perform the necessary traverse of the slots 12, and also prevents yawing of the access panel 5.
  • Figures 2 to 7 illustrate the sequential stages of movement. Pivotal movement of the panel 5 at all stages is about the pins 13, but as the panel pivots the pins 13 are forced to move longitudinally along the slots 12. The maximum traverse of the pins 13 down or along the slots 12 is when the axis of the pins 13, the first hinge axis 15 and the second hinge axis 17 are in a straight line (at the stage of opening shortly after that of Figure 6) and after that the pins move slightly back along the slots 12.
  • cam tracks 12 are enclosed double-sided slots, the panel closing movement is controlled in an entirely analogous manner.
