Definitions

  • the present invention relates to a hinge-down ceiling panel assembly and a suspended ceiling system provided with hinge-down ceiling panel assemblies.
  • Conventional suspended ceiling systems include a network of support members and ceiling panels, which rest on, and are supported by, the support members. These panels are often capable of being pivoted, i.e. hinged, downwardly in order to access the space between the grid and the overhead ceiling.
  • Such a system is known from FR-A-2 639 387 .
  • the ceiling system 10 includes support members 12 and a hinge-down panel assembly 14.
  • the support members 12 extend in one direction, and are in spaced, parallel relation to one another.
  • the support members 12 can be suspended in any suitable way.
  • the support members 12 provide a horizontally extending support for the hinge-down panel assembly 14.
  • Figure 1 illustrates support members having U-shaped profiles.
  • the support member 12 has a lower horizontal surface 16 and first and second vertical surfaces 18, 20 extending from opposing edges of the lower horizontal surface 16. Extending from an edge of each vertical surface is an end return flange 22, 24.
  • the end return flanges 22, 24 extend inwardly and are in substantial parallel relation to the lower horizontal surface 16.
  • a hinge-down panel assembly 14 spans the distance between two adjacent support members 12.
  • the hinge-down panel assembly 14 includes a panel 32 of rectangular shape having a bottom surface 36 and two pairs of opposing sidewalls, namely a first sidewall 43, opposite thereto a second sidewall 41 and a third sidewall 40 and opposite thereto a fourth sidewall 42.
  • the sidewalls 40, 42 and 41, 43 extend substantially vertically from the horizontal bottom surface 36.
  • Each one of the third and fourth sidewalls 40 and 42 includes a pair of keyed apertures 64 into which can be inserted attachment hardware for attaching the hinge-down panel assembly 14 to the support members 12.
  • the attachment hardware of the hinge-down panel assembly 14 includes pivot members 44 and slide members 50.
  • the hinge-down panel assembly 14 as shown in Fig. 1 comprises two pivot members 44 each being engaged with an end of the first sidewall 43 and held on the support member 12, and two slide members 50, each being engaged with an end of the second sidewall 41 and releasably held on a support member 12.
  • the slide member 50 comprises a rod that can be divided into a first portion 54, a second portion 56 aligned to the first portion 54 and a third portion 62 extending outwardly from and between the first portion 54 and the second portion 56.
  • the slide member 50 further comprises a U-shaped profile having a web 103, two legs 102 and two outwardly bent extensions 104.
  • the legs 102 are provided with respectively opposite apertures 101, through which the rod extends such that its first portion 54 extends between the third portion and the one leg 102.
  • This first portion 54 is surrounded by a coil spring 58 abutting against the third portion 62 and the one leg 102.
  • the second portion 56 extends through the aperture 101 in the other leg 102.
  • the rod extends parallel to the web 103 through the apertures 101 and beyond the legs 102.
  • the extensions 104 are parallel to the web 103 and provided with holes 105 for being fixed to the second sidewall 41 by means of screws, rivets or the like.
  • the second portion 56 extends through the third sidewall 40 and can be supported by the end return flange 22.
  • the third portion 63 extends through a slot 66 in the second sidewall 41.
  • Each pivot member 44 consists of a first portion 46 provided with an angle 49 and a second portion 48 perpendicularly bent with respect to the first portion 46 and being longer than the width of the first portion 46.
  • the angle 49 is substantially parallel in its extension to the second portion 48 of the pivot member 44.
  • the long second portion 48 of the pivot member 44 extends in the space between the bottom surface 36 and inwardly folded upper edges of the sidewalls 40, 42, while the first portion 46 of each pivot member 44 rests on the surface of the end return flanges 22, 24, and is securely held by means of the angle 49 extending below the respective end return flange 22, 24.
  • the hinge-down ceiling panel assembly according to the above-discussed prior art needs great effort for manufacturing and installing the slide members as riveting, screwing, welding and the like is requested in order to attach the premanufactured slide members to the panel.
  • the parts can be manufactured by simple punching or stamping and bending steps and can be easily assembled by manual plugging. Because of the simplified structure of the slide members and the pivot members, no special tool is required to slide the third portion from the first position to the second position.
  • any handy implement such as a screwdriver, can be inserted into the clearance between the vertical walls of the panel and the adjacent support member. With the third portion in the second position, the first portion of the slide member no longer engages the profile and is clear of the edge of the profile.
  • the panel is free to swing downwardly by pivoting about the pivot members and hang freely from the pivot members to permit access to the functional elements contained in the space above the horizontal suspended ceiling plane.
  • it is unnecessary to remove the panel from the ceiling in the process of getting at the space above the ceiling plane. Further, there is no screwing, riveting or welding operation for fixing the parts.
  • FIG. 4 is a perspective view of a portion of a suspended ceiling system containing the hinge-down panel assembly in accordance with an example embodiment of the present invention.
  • FIG. 5 is a perspective view of the hinge-down panel assembly of the invention.
  • FIG. 6 is a perspective view of the slide member of the invention with coil spring.
  • FIG. 7 is a perspective view of the pivot member of the invention.
  • FIGS. 8 and 9 are perspective detailed views of corners of the panel assembly showing the slide member of the invention with the slide member attached to the panel and resting in the first position.
  • FIGS. 10 and 11 are perspective detailed views of corners of the panel assembly showing the pivot member attached to the panel.
  • FIGS. 12 and 13 are perspective detailed views of corners of the panel assembly showing the slide member with coil spring of the invention attached to the panel and retracted in the second position.
  • the pivot member 44 has a body 45 which includes a first portion 46 and a second portion 48.
  • the first portion 48 of the pivot member includes an angle 49 which extends integrally therefrom and is bent in a direction generally perpendicular to the body 45.
  • the angle 49 assists in horizontally locking the panel assembly 14 to the support members 12 of the grid.
  • the angle 49 is critical in keeping the panel on the support members when the panel is in the hinged-down position.
  • the second portion 48 of the pivot member has a tapered edge 47.
  • the first portion 46 of the pivot members 44 is inserted through a slot 52 in the fourth sidewall 42 of the panel 32.
  • the slot 52 is positioned proximate a corner of the panel 32.
  • the first sidewall 43 includes a bend tab 70', or latch, which is notched out of sidewall 41.
  • the bend tab 70' is bent inwardly to a position substantially perpendicular to vertical wall 43 and, therefore, parallel to vertical wall 42.
  • the point of bending can include a relief slot 71 for ease in bending.
  • the bend tab 70 includes a slot 72' into which the tapered edge 47 of the second portion 48 of the pivot member body 45 is inserted.
  • the slot 72' is positioned on the bend tab 70' such that it is in vertical alignment with slot 52.
  • the bend tab 70' serves as an abutment for the pivot member body 45.
  • each slide member 50 has a body 51 which includes a first portion 54 and a second portion 56.
  • a helical compression spring or coil spring 58 encircles the first portion 54 and is attached to the first portion via notching 60 at the base of the first portion 54.
  • the second portion 56 of the slide member 50 extends integrally form the first portion 54 and has a width greater than the first portion 54.
  • the second portion 56 functions as an abutment piece for the coil spring 58.
  • the second portion 56 includes a third portion or an ear 62 which extends outwardly from the base of the second portion 56 in a direction transverse to the first portion 54 of the slide member 50.
  • the first portion 54 is inserted into and through a slot 64 in the third sidewall 40 of the panel 32, the slot 64 being positioned proximate a corner of the panel 32.
  • Figures 5 and 9 illustrate the slot 64 with the second portion 56 of the slide member 50 seated therein.
  • the ear 62 of the second portion 56 is then inserted through a slot 66 in the second sidewall 41 located adjacent the third sidewall 40 containing the slot 64 into which the second portion 56 of the slide member 50 is inserted.
  • These two slots, 64 and 66 are in vertical alignment with one another. As shown throughout the drawings, adjacent vertical sidewalls are essentially perpendicular to one another, and, thus, the two slots, 64 and 66, are also in perpendicular relation.
  • the second sidewall 41 includes a bend tab 70 formed in the second sidewall 41.
  • the bend tab 70 is positioned on the side of the ear slot 66, distal to the slot 64.
  • the bend tab 70 is bent inwardly to a position substantially perpendicular to the second sidewall 41 and, therefore, parallel to the third sidewall 40.
  • the point of bending can include a relief slot 71 for ease in bending.
  • the bend tab 70 includes a slot 72 into which the first portion 54 of the slide member 50 is inserted.
  • the slot 72 is positioned on the bend tab 70 such that it is in vertical alignment with slots 64 and 66.
  • the bend tab 70 serves as a second abutment for the helical compression or coil spring 58, and thus, the spring 58 interposes the second portion 56 and bend tab 70.
  • the spring 58 When the slide member 50 is attached to the panel, the spring 58 is somewhat recoiled, and, thus, exerts a force on the ear 62 of the slide member 50 and pushes the ear 62 against the edge of slot 66 which is proximate the third sidewall 40.
  • This position is hereafter referred to as the first position and is best illustrated in Figure 8 .
  • the first position the second portion 56 of the slide member 50 extends from the interior of the panel 32, through the slot 64 and beyond the outer surface of the third sidewall 40.
  • the ear 62 of the slide member 50 In order to move the panel 32 from its hinged-down position as shown in Figure 4 , into the horizontal planar position, the ear 62 of the slide member 50 must be moved from the first position in slot 66 to a second position.
  • the spring 58 In the second position, the spring 58 is further recoiled and the second portion 56 of the slide member 50 is retracted substantially into the interior of the panel 32, such that the second portion 56 does not extend out
  • the panel 32 is then pivoted upwardly about the pivot members 44 until the slide members 50 are at a higher position than the end return flanges 22, 24 of the support members 12.
  • the ear 62 of the slide members 50 are released which will permit the spring 58 to press the slide member 50 back into the first position.
  • the first portion 56 of the slide member 50 will project over and above the end return flanges 22, 24 of the U-profile support members 12 and will rest on the end return flanges 22, 24, effectively locking the panel assembly 14 in the horizontal ceiling plane.
  • Both the pivot members 44 and the slide members 50 are made of flat stamped metal, preferably sheet metal and are mounted by being inserted or plugged and positioned in associated slots 52, 64, 66; 72, 72' pinched in the sidewalls 40 to 43 and in notched out bend tabs 70, 70', respectively.
