  • the coupling ring 118 is coupled with the claw ring 140, such that rotation of the coupling link 118 in this direction brings about simultaneous rotational movement of the claw ring 140 in the same direction through the same angle. Because of the engagement between the claw ring 140 and the rotatable member 138, rotation of the claw ring 140 in turn brings about corresponding rotational movement of the rotatable member
  • the rotatable member 138 rotates through 60°, so as to bring a protruding portion 146 of the operating part 144 of the rotatable member 138 to bear on the central upwardly-bent portion 108a of the intervening rod 108, and against the upward biasing force of the leaf spring 112.
  • the arches 106 are pivoted to the ring-closed position, in which the arches 106 mate with the posts 104 to close the two rings.
  • the lever assembly is designed such that the pivoting angle of the coupling link 118 is twice of that of the operating link 114.
  • the angle through which the operating link 114 travels between its stable upper position and its lower position is 30°, so that through each downward pivoting movement of the operating link 114, the coupling link 118 (and thus the claw ring 140 and the rotatable member 138) rotates in the direction indicated by the arrow R by 60°, which is the angle between adjacent alternating protruding portion 146 and recessed region 148 of the operating part 144 of the rotatable member 138.
  • the operating link 114 When the downward force acting on the operating link 114 of the lever assembly is released, the operating link 114 will return, upon the biasing force of the spring 134, to its stable upper position, as shown in Figs. 12 and 13. During this upward pivoting movement of the operating link 114, it causes the coupling link 118 to rotate in a direction opposite to the direction indicated by the arrow R in Fig. 3.
  • each of the claws 156 is again received within a respective hole 162 of the plate 160 of the coupling link 118.
  • the coupling link 118 rotates in the direction indicated by the arrow R in Fig. 3 to bring about corresponding rotational movement of the claw ring 140 and the rotatable member 138, so as to bring an adjacent recessed region 148 of the rotatable member 138 into engagement with the central upwardly-bent portion 108a of the intervening rod 108, so as to allow the leaf spring 112 to pivot upwardly to pivot the arches 106 away from the posts 104 to open the rings, whereby the mechanism 100 assumes the ring-open configuration, as shown in Figs. 3 to 9.
  • a paper-retaining mechanism possesses at least the following advantages: a. because of the angle magnification characteristic of the lever assembly, the user only has to pivot the operating link 114 downward by 30° to bring about a 60° rotation of the rotatable member 138, which renders the mechanism 100 easy to operate; b. in contrast with conventional mechanisms, opening and closing of the rings is brought about by a same downward pivoting movement of the operating link 114 from its stable upper position, thus simplifying operation of the mechanism 100; c. after each downward pivoting movement, the operating link 114 is returned, under the upward biasing force of the spring 134, to its stable upper position, to be ready for the next operation; and d. even when in its stable upper position, the operating link 114 is sufficiently spaced apart from the posts 104 and arches 106, so as to allow pieces of hole-punched paper to be retrieved from or inserted into the posts 104 and the arches 106.
  • the mechanism 100 may be secured, e.g. by rivets or screws, to a substrate, e.g. a cover made of cardboard, plastics, metal or a combination thereof, to form a document file or holder.
