  • the latch bar dog 212 of the pass door is actuated by applying a suitable handle to shaft 440, which handle also operates to extend Iand retract the seals 112 and 114 of the pass door.
  • this mechanism is shown with the seals in their extended position and the latch bar in its locking position and the seals are retracted by rotating the shaft 440 inV a clockwise direction to throw the linkage 214 lever 446 which is fixed t-o the shaft 210 through a link 444 that is pivotally connected to same and lever 442 which is keyed to the shaft 440.
  • This motion also actuates lever 450 that is keyed to shaft 440 to move same in a clockwise direction and draw the latch bar 212 to the right of FIG- URE 2 through a link 452 that is pivotally connected between the lever 450 and the latch bar 212. Extension off the seals and locking of the latch door is accomplished by movement in the other direction and the latch bar may be conveniently locked in place by employing a lock and key mechanism which fixes the lever 442 against rotation when it is positioned as shown in FIGURE 1.

  • cover yarrangements lhaving the same thickness dimension are shown in FIGURES 8 and 9, and as shown in FIGURE 8, the cover may comprise a gypsum board 464 having a vinyl covering 466 of appropriate aesthetic appearance, or as indicated in FIGURE 9, the cover may comprise a hardboard sheet 468 having a chalkboard facing 470 (for an overall thickness of one-eighth of an inch) to which is secured a three-eighths inch gypsum board 472.
  • FIGURE 6 The cover form of FIGURE 6 is an -alternate to that shown in FIGURE 7 for applications where a thicker cover is desired and comprises a plywood or hardboard facing 474 of one-quarter inch thickness to which is applied a gypsum board 476 of one-half inch thickness.
  • the tackboard 332 and its cover 334 would have an overall thickness of three-eighths of an inch
  • the gypsum board 236 has a thickness of three-eighths of an inch for a total cover thickness of three-quarters of an inch except about the rim of the cover that is thus reduced in thickness for application into the respective recesses 66, 76, 182 and 184.
  • an operable panel type partition arrangement including an overhead trackway, and a plurality of at least two panels each having opposed faces and hinged together in side-fby-side relation for movement between wall forming and wall folded positions, an overhead trackway defining the path of movement of the panels between their said positions, and carrier meansriding along said trackway and supporting the respective panels for suspending the respective panels for movement between sai-d positions, the improvement wherein said panels each comprise:
  • top and bottom members disposed in substantially parallel horizontal relation and spaced side members disposed in substantially parallel vertical relation with their ends positioned in juxtaposed relation with the ends of the respective top and bottom member
  • means for releasably securing the ends of the respective side frame members to the ends of the respective top and bottom members adjacent same including means for releasing said securing means at said ends of one of said side members and for separating said one side member from the adjacent ends of said top and Abottom members by moving same away therefrom in the plane of the panel defined by said members,
  • said frame members each being formed to define in the secured relation thereof cover edge receiving recesses aligned in circumambient coplanar relation about the respectivefaces of the respective panels and defining a mounting recess structure
  • said recesses being formed to preclude movement of said covers normal to their respective planes
  • said covers being secured to the respective panels by having their edges received in the respective mounting recess structures with said one side member secured to said frame by said securing means, and said covers of each panel being isolated from each other except at said recess structure for maximum sound loss characteristics
  • each frame member is of generally channel shaped transverse cross-sectional configuration, with each frame member defining in transverse section a web portion having spaced flange portions projecting laterally thereof from the longitudinally extending edges of the web portion,
  • said securing means comprising an arm member at each of said corner portions secured to the frame top and lbottom members respectively and being in abutting relation with the inwardly facing sides of the respective frame side member web portions,
  • each of said panels further includes:
  • said load transmission member having a length that is at least on the order of one half the length of said top frame member and having its ends secured to said top frame member,
  • said load transmisison member being spacedfrom said top frame member intermediate its ends
  • said tying means comprising:
  • said rod member being parallel to said top and bottom frame members
  • a grip member mounted within the ange portions of the respective top and bottom members for shifting movement outwardly and inwardly of said frame in the plane thereof between retracted and extended positions
  • top frame member grip member having a key hole slot formed therein
  • said one portion of said slot being wider than the other portion thereof and said rod means being proportioned to fit through said slot one -portion for application to said top frame member grip member and to operate in said slot other portion,
  • said rod means including a head portion proportioned to oppose withdrawal of same through Said slot other portion.
  • said frame member recesses are proportioned to alternately receive covers of several diiferent thicknesses.
