  • lever members 134 and 164, ends 156 and 182, respectively, of the actuator mechanism 40, as shown in FIG. 3, are not necessary insofar as the biasing of the grip member 44 is concerned.

  • the spring 254 acts on the grip member 44 through a mechanical advantage, which is represented by the distance A of FIG. 6, that increases as the grip member moves toward its extended position, while the levers 230 and 232 act on the grip member through a mechanical advantage, represented by the distances marked B in FIG. 6, which decreases as the grip member moves to its extended position. It is this combination of variables plus the tension in spring 254 that results in the spring pressure curve of FIG. 12.
  • the special essence of the actuator mechanism 40 lies in the combination of compound lever and tension spring principles.
  • the resultant force in the configuration involved will increase in proportion to applied force due to the changes in lever geometry as the grip member rises upward.
  • the length of the spring applying the operating force decreases.
  • the force applied decreases approximately linearly as the spring contracts.
  • the net resultant is a controllable characteristic curve determined by lever geometry as modified by spring linearity, increasing in upward pressure as grip member rises and decreasing as it lowers precisely as desired for seismic conditions on the one hand or roof loading on the other.
  • the vital essence of this aspect of the invention remains as long as the geometry of the levering is working in the same way relative to spring physics to produce a similar characteristic curve.
  • the curve 195 (FIG. 12) may be moved" to the left or the right on the graph by positioning cross levers 130 and 132 closer together or further away from each other. This may be accomplished by providing a suitable selection of pivot holes in the brackets 144 and 154, whereby, assuming that the same tension springs 190 and 192 are employed, the upward pressure of the grip member 44 throughout the range of the curve will be less if the cross lever pairs 130 and 132 are moved closer together and more if they are moved further apart.
  • This principle may be employed to advantage when using the same actuator mechanism in panels of different width, i.e., in order to provide the same upward pressure per foot of panel width.
  • FIGS. 13 and 14 Similar results can be obtained by employing the actuator linkages diagrammatically illustrated in FIGS. 13 and 14.
