Definitions

  • Ring mechanisms for loose leaf books are known in which the rings are opened and closed directly by hand.
  • This primitive type has the disadvantage that especially with rings of small diameter and a thick insertion of paper it is diflicult to grasp the rings.
  • levers are provided at the ends of the mechanism which are either turned upwards or outwards or are displaced in the longitudinal direction of the 1 mechanism in order to open the rings.
  • the rings are closed in these constructions usually by pressing together the sections of the rings or also by a reversal of the opening movement.
  • These constructions have the disadvantage that they possess projecting parts which are easily deformed and may damage the pockets and also require the use of both hands to operate them.
  • Also there are devices with press buttons in the back of the book which are used only to open the rings.
  • the present invention relates to a ring mechanism in which two press buttons are arranged, for example, at the ends, one of which when depressed swings the ring strip by means of an intermediate member or the like over the dead position to its upper position whereby the rings are opened while the second engages directly 0 with the ring strip and when depressed serves for swinging the ring strip over its dead position to its lower position so that the rings are closed.
  • FIG. 1 shows a'perspective view of the closed arrangement
  • Fig. 2 is an elevation of the press button for opening therings.
  • Fig. 3 is a perspective view of the intermediate member belonging to the said button
  • Fig. 4 is an elevation of the press button for closing the rings
  • Fig. 5 is a longitudinal section
  • Fig. 6 is a cross-section through the device while the rings are closed
  • Fig. 7 is a longitudinal section
  • Fig. 8 is a cross-section through the device with the rings open, and,
  • Fig. 9 shows a plan view with the covering strip removed.
  • Fig. 1 shows a perspective view of the closed. arrangement in which b is the button for opening in its raised position and a is the closing button in its depressed position.
  • buttons b for the opening are shown separately.
  • a pin riveted to the base strip e (Fig. 5).
  • a slot d for receiving the end g of an intermediate member h (Fig. 3).
  • This intermediate member which has the object of converting the downwardly directed movement of the button 1) into an outwardly directed movement of the ring strip, has two small hooks i for being pivotally suspended in slots of the ring strips Z and an extension which comes into engagement at the abutment places of the two ring strips and swings the latter outwards, when operated, over the dead position against the spring force of the base strip e and thereby opens the rings and at the same time moves the button a into its raised position.
  • a recess m in the button a enables it to be clamped between the ring strips.
  • the two ring strips are swung downwards over the dead position against the spring force of the base strip e and thereby the rings are closed.
  • the ring strips have a plurality of lugs 17 on their lower side.
  • Fig. 5 is a longitudinal section and Fig. 6 a cross-section through the device while the rings are closed and Figs. 7 and 8 are similar views with the rings open. From this will be seen the two positions of the two buttons corresponding to the open and closed device as well as the method of engagement of the intermediate member h.
  • Fig. 9 is a plan view with the covering strip removed.
  • a ring mechanism for loose leaf books having ring'stripsconnected with the rings, said strips being held in toggle relationship by a spring base strip, a press button at one end of the device, an intermediate member connecting this press button with the ring strips so that when the button through the dead center position, thereby opening the rings, and a second press button engaging directly with the ring strips and adapted when depressed to swing the ring strips downwardly into their lower position, thereby closing the rings.
