Definitions

  • a spring is 5 also provided by which the lever, the press stud or the like, is supported so as to prevent the same from shaking.
  • the drawing illustrates by way of example a construction of mechanical actuating device according to the invention.
  • Fig. 1 is a perspective view of the ring book mechanism.
  • Fig. 2 a longitudinal section of the mechanism on line A-A of Fig. 3, when the mating prongs are closed to form rings and with the cover plate omitted, and Fig. 3 a cross section thereof on line B-B of Fig. 2.
  • Fig. 4 is a longitudinal section of the mechanism on the line -0 of Fig. 5 with the mating prongs parted so as to open the rings, and Fig. 5 a cross section thereof on line DD of Fig. 4.
  • Figs. 6 and 7 represent the opening and closing levers.
  • the ring book mechanism consists of the usual resilient base plate I in which a pair of toggle connected ring plates 2 are inserted.
  • the prongs 3 are fixed to the ring plates 2, and the 3%) prongs are parted and the rings formed by the prongs opened when the ring plates 2 are raised against the influence of the resiliency of the base plate I (Figs. 4 and 5) and the prongs are brought together and the rings closed when the ring plates are pressed down (Figs. 2 and 3).
  • a cover 4 is further laid over the ring plates, and connected to the base plate I.
  • the ends of the ring plates 2 are provided with slots 5 for the engagement of bent over projections 6 of an open- 40 ing lever I and a closing lever 8 while the lower end of the opening lever I carries an extension ,9 directed upwardly, another similar extension I0 directed downwardly is provided on the closing lever 8 approximately in its center.
  • a spring I I which presses against the lower side thereof and is with advantage bent out from the material of the base plate I. In order better to distinguish the different duties of both levers, these may be either in different colors or distinguished by markings or the like for the opening and the closing respectively.
  • a resilient base plate a pair of ring-carrying toggle plates supported by said base plate to have movement toward and away from the base plate and arranged with slots adjacent one end, a closing lever at said end having a convex under surface on which it rolls, two fingers which extend from one end of said lever and which are adapted to pass through the slots in the toggle plates and to act as supports about which the lever swings, the opposite end of the lever extending from one end of the base plate and toggle plates, and a third finger on said lever adapted to engage the upper surfaces of said toggle plates and to exert a downward pressure thereon when the said opposite end of the lever is pushed outwards and downwards to rock the lever.
  • ring book mechanism in ring book mechanism according to claim 1, a part of the base plate belowthe closing 1ever severed to form a leaf spring which serves as a resilient support for the convex under surface of the closing lever.
  • a resilient member carried by the base plate and serving as a support for the convex under surface of the closing lever.
