Definitions

  • a cross member is provided with a flange which is placed in the edge kerf of ceiling boards.
  • the cross member supports the ceiling boards in position.
  • a joint structure is provided to connect together two adjacent cross members.
  • the joint structure is so arranged with a slot and tab that the two cross members can be somewhat adjustable in length.
  • the invention is directed to a suspended ceiling system and, more particularly, to a joint structure for cross members of the suspended ceiling system.
  • U. S. Pats. No. 2,710,679 and No. 3,374,596 are two typical examples of suspended'ceiling systems and the joint structures used to fasten together the ceiling suspension members.
  • the first-mentioned patent uses a plate structure 16 to function as a splice clip to hold adjacent support members together.
  • the secondmentioned patent has the ends of the support members so formed that they can lock together. Neither of these two structures are capable of adjustment.
  • the primary inventive feature herein is the end detail for a cross member of a suspended ceiling system.
  • Each oftwo adjacent ends of the members has a slot or opening in the extension from the vertical rib of the cross member.
  • each extension has a tab extending to either side of the extension.
  • Two adjacent cross members are placed end-to-end with the extensions being placed side-by-side. When this is done, one of the tabs of the one cross member extends into the slot of the adjacent cross member and vice versa relative to the other slot and tab construction. Whenever a force is moved in a direction perpendicular to the plane of the flanges of the cross members, there will be no movement of the two cross members at the joint structure.
  • the joint structure herein is particularly useful for the ordinary homeowner who is putting up his own ceiling system.
  • a joint structure which can be readily fastened together and will allow the homeowner a certain degree of adjustability so that he need not place the ceiling system together with the high degree of accuracy which is normally required with conventional ceiling suspension support structures.
  • FIG. I is an exploded isometric view of the invention herein;
  • FIG. II is a top view of the assembled joint structure.
  • the cross member assembly 1 is the element that supports the ceiling panel if it is the type of panel which has a kerf in its edge to receive the flange of the cross member.
  • the cross members are usually supported from main runner members.
  • the main runner members are supported by wires from the structural ceiling of a room.
  • each of the members has an extension 2 which extends out beyond the main body portion of the cross member.
  • the main body portion of the cross member is composed of a vertical rib structure 3 and a horizontal flange structure 4 which extends out on either side of the vertical rib 3.
  • the extension 2 of the cross member has the joint structure which is used to fasten together the two adjacent cross members.
  • Each of the extensions 2 has a slot or opening 5 and two offset tabs 6. On each extension, a tab extends to either side of the extension portion of I the cross member.
  • the particularly nice feature of the tab and slot structure above described is that it will permit an adjustment or expansion of the overall cross member structure. That is, the cross member structure will be permitted limited movement along the axis of the cross member, along the direction of arrow 11, to permit a relative adjustment of the length of two adjacent cross members.
  • the cross members are generally sold in approximately four-foot lengths. If one were installing the ceiling system in a room that had a little less than eight feet between two adjacent walls, the adjustability feature afforded by the tabs and slots would permit one to extend the cross member system out until it approximately filled the distance between two adjacent walls.
  • the system is very easy to assemble together, there being no need to lock together different tab structures or plates.
  • the ceiling system is installed, it is possible that there can be a little give in the cross member structure so that the cross members can slide relative to each other. This feature is of some value, should there be a fire and there be the generation of sufficient heat to cause expansion of the cross members. if no expansion of the cross members were permitted, the cross members would tend to buckle.
  • a suspended ceiling system including a plurality of frame members which are utilized to suspend ceiling panel structures in position, at least two cross member structures placed in an end-to-end relationship, the improvement comprising an improved joint structure for fastening together the cross members, each of said cross members having an extension projecting outwardly from the cross member, the main body of the cross member being composed of a vertical rib and a horizontal flange and the extension extends outwardly from the vertical rib, each extension on each cross member having an elongated slot structure therein and two bent-out tabs extending on opposite sides of the plane of the extension, said two extension members being placed in a side-by-side relationship, and when the extension members are in a side-by-side relationship, at least one tab of an extension member being inserted into the slot of the adjacent extension member whereby the cross member structures are capable of adjustment along the longitudinal axis of the cross ,members and will be able to restrain separation against a force applied in a direction in a line perpendicular to the horizontal flange in
