Definitions

  • ABSTRACT A loose-leaf binder mechanism is disclosed which includes a case containing a pair of pivotally mounted hinge plates each carrying a series of spaced prongs.
  • the hinge plates are movable between two alternate positions. In one of these positions the prongs are closed together to define a loose-leaf sheet retaining loop and in the other position the prongs are spread apart.
  • the binder mechanism also includes a specially constructed operating lever to move the hinge plates between the two positions. One portion of the lever is selectively moveable along a predetermined arcuate segment of the path of movement of the lever into a wedged-in position between the case and hinge plates to lock the prongs in closed position.
  • the lever is specially constructed so that it can be moved while wedged between the caseand hinge plates to a safetylock position such that any point of contact between said one portion and the case is advantageously disposed longitudinally inward of any point of contact between said one portion and the hinge plates and so that it cannot be moved inward past the safety-lock position out of wedged-in relationship between the case and hinge plates.
  • This invention relates generally to loose-leaf binders and more particularly to loose-leaf binder mechanisms of the type which are commonly known as ring binders.
  • binders include an elongated case or cover containing a pair of pivotable elongated hinge plates each of which carries a series of spaced apart prongs. Each prong on one hinge plate is aligned with a prong on the other hinge plate.
  • the hinge plates may be pivoted relative to each other between two positions.
  • the aligned prongs engage each other to form a closed loose-leaf sheet re taining loop; and in the other position each pair of aligned prongs is spread apart to permit removal or insertion of loose-leaf sheets.
  • the prongs can be used as levers to move the hinge plates between the two positions, such binders commonly include separate lever-type actuating means for pivoting the hinge plates between the open and closed position as exemplified in the following U.S. Pat. Nos. 1,787,956, 1,841,793,
  • the present invention was conceived in an effort to construct a relatively inexpensive, reliable and easy-touse locking ring binder mechanism.
  • This effort has successfully resulted in a novel and unobvious improved ring binder mechanism which in addition to combining the locking and actuating functions in a lever-type actuator also combines a unique and novel safety lock feature in the lever-type actuator to prevent accidental release of the lock.
  • the construction of this triplefunction lever-type actuator is summarized in the immediately-following section of the specification and described in detail with respect to the presently preferred embodiment shown in the drawings in the remaining portion of the specification following the summary.
  • the binder of this invention includes an elongated case or cover within which a pair of resilient elongated hinge plates are pivotally mounted with the pivot axis of each extending longitudinally along its outer edge; the inner edges of the hinge plates being disposed in abutting relationship for all angular positions of the hinge plates.
  • Each hinge plate carries a series of longitudinally spaced apart prongs with each prong on one hinge plate being aligned with a prong on the other hinge plate.
  • the hinge plates are selectively movable between an inwardly bowed position .and an outwardly bowed position.
  • the hinge plates In the former position, the hinge plates extend inwardly of the case with their surfaces mounting the prongs facing away from each other; each pair of aligned prongs being th'us spread apart to permit insertion and removal of loose-leaf sheets.
  • the hinge plates extend outwardly of the case with their prong mounting or carrying surfaces facing each other; each pair of aligned prongs thus engaging each other to define a closed loose-leaf sheet retaining loop.
  • an actuating means is provided for moving the hinge plates between the two described positions.
  • the actuating means comprises a pivotable lever member or element engaging the hinge plates, hinge plate depressor means responsive to movement of the lever for moving the hinge plates from the inwardly to outwardly bowed position and hinge plate lifting means also responsive to movement of the lever for moving the hinge plate from the outwardly bowed position to the inwardly bowed position.
  • the lever is, more particularly, operable upon being pivoted in one direction through one predetermined arcuate segment of its path of movement to apply an outwardly directed force on the inwardly bowed hinge plates with enough leverage to move them through the coplanar position to the outwardly bowed position.
  • the lever Upon pivoting of the lever through the same arcuate segment in the reverse direction, the lever is operable to apply an inwardly directed force to the outwardly bowed hinge plates sufficient enough to move the outwardly bowed hinge plates through the coplanar position back to the inwardly bowed position.
  • the lever is so constructed that a portion thereof can, simply by moving the lever into any one of a range of angular positions disposed along another predetermined arcuate segment of its path of movement, be selectively wedged tightly between the outwardly bowed hinge plates and the case to lock the prongs in closed position.
  • the lever can be moved between a first position such that an imaginary line interconnecting any point of contact between the wedged-in portion of the lever and the case with any point of contact between the wedged-in portion of the lever and the hinge plates is oriented at an upwardly inclined outwardly extending attitude relative to the case and a second position such that said imaginary line is oriented at an upwardly inclined inwardly extending attitude relative to the case.
  • the improved actuating means of this invention includes a stop lock means for preventing inward pivotal movement of the lever to any position beyond said second position where its wedgeable portion would cease to be wedged between the case and outwardly bowed hinge plates.
  • the hinge plates are locked in the outwardly bowed position, the aligned prongs being thereby locked in closed position, at all lever positions where its wedgeable portion is wedged between the case and outwardly bowed hinge plates. And, importantly, by moving the lever from said first wedged-in position described above past the center wedged-in position into the said second wedged-in position described above, an effective safety for the lock is provided making the chances of the locked prongs becoming accidentally jarred open or otherwise unintentionally released virtually non-existent.

  • the loose-leaf binder of this invention includes an elongated case member 1, a pair of elongated hinge plates 2 and 3 each of which carries a series of prongs 2 and 3', respectively, and an actuating lever 4 located at each end of the case member.
  • case 1 and hinge plates 2, 3 are made of a relatively stiff spring-like metal the purpose of which will become apparent as the description continues.
  • the case 1 and hinge plates 2, 3 may, however, be made of material other than metal provided it is relatively stiff and exhibits spring characteristics.
  • the entire assembly is secured to the spine 5a of a typical loose-leaf book cover 5 by means of rivet 6 extending through hinge plates 2, 3 to connect case 1 and book cover 5 together.
  • Case 1 has a generally arched cross-sectional configuration with the crown of the arch up and with its marginal longitudinal edges 7 being curled under or down to form elongated hinge pockets 8.
  • Each pocket so formed receives the outer longitudinal edge of one of the hinge plates and generally defines the pivot axis for that hinge plate.
  • the inner longitudinal edges of hinge plates 2 and 3 abut each other along their entire length as shown; the hinge plates being retained in abutment along their inner edges at all angular positions by cleats 6b which are formed along the inner longitudinal edge of one hinge plate to overlap the abutting edge of the other hinge plate.
  • each prong 2' on hinge plate 2 is aligned with a prong 3' on hinge plate 3.
  • the hinge plates are movable between two positions. One position is best shown in FIG. 5a where it will be seen that hinge plates 2 and 3 are bowed slightly outwardly of case 1 with their prong carrying or mounting surfaces facing toward each other. In this position each pair of aligned prongs 2', 3 forms a substantially closed loop or ring for retaining loose-leaf sheets appropriately punched with holes to accept the prongs.
  • FIG. 6a The other position of the hinge plates is best seen in FIG. 6a.
  • hinge plates 2, 3 are bowed inwardly of case 1 with their prong carrying or mounting surfaces facing away from each other; each pair of aligned prongs being thereby spread apart to permit insertion or removal of loose-leaf sheets onto or from the sheet retaining loops.
  • the combined width of the hinge plates 2, 3 is slightly greater than the distance between the pivot axes defined by hinge pockets 8. Movement between the inwardly and outwardly bowed positions occurs without causing disengagement of the inner edges of the hinge plates. That is, the inner edges of the hinge plates abut each other at all angular positions.
  • the hinge plates 2,3 are thus first moved, say, from the outwardly bowed position into a position at which they are disposed in substantially coplanar relationship, the case flexing or distorting somewhat at this point to accommodate the hinge plates as they move through this coplanar position.
  • the hinge plates then continue into the inwardly bowed position by a snap action as the pressure existing at the coplanar position is relieved and the case naturally unflexes into a semi relaxed state.
  • the actuating lever is best shown in FIG. 4 where it will be seen that it includes an actuator portion indicated generally by reference numeral 11 and a trigger portion indicated by reference numeral 12.
  • the binding mechanism shown in the drawings includes two such levers positioned at opposite ends of case 1.
  • the actuator portion of the lever has a transversely arched body 13 which conforms generally to the arched curvature of case 1.
  • Body 13 extends in generally parallel offset relationship to trigger 12 in the sense that a plane tangentially disposed to the central portion of body 13 would extend parallel to and spaced from the trigger 12.
  • the upper edge 16 of body 13 is also curved or arched transversely widthwise of case 1 with a curvature conforming generally to the curvature of arched case 1.
  • the crown of arched edge 16 and the crown of arched body 13 extend generally in perpendicular directions with respect to each other. As shown,
  • the retaining member 15 connects the trigger 12 and body 13 together.
  • the retaining member 15 includes two sections 15a and 15b disposed substantially perpendicular to each other. Section 15a is connected at one end to body 13 and at the other end to section 15b. As will be clearly seen in a later portion of the description, the section 150 extends from body 13 longitudinally outward of case 1 in closely spaced relationship to the-undersurface thereof for all locked positions of the lever and the section 15b which is situated exteriorly of the case engages a seating surface 15c defined by the end of case 1 to prevent inward pivotal movement of the lever beyond a certain locked position.
  • section 15a and case 1 are provided to eliminate any possibility of preventing or restricting proper lever movement due to interference between section 15a and the case 1 as the lever is moved to a locked position.
  • end portion of case 1 is formed with a recessed area 15d located directly over the path of movement of section 15a into the case during movement of the lever to locked position.
  • leg element 14 Depending from each end of the lower edge 17 of body 13 is a leg element 14 the tip 14a of which is bent toward trigger 12 to lie in a plane which intersects a plane lying tangent to the body 13 at the junction of each leg element. As best shown in FIG. 3, these leg elements engage notches 18 formed in the outer edges of hinge plates 2, 3. The corners 14b between leg elements 14 and lower edge 17 contact the hinge plates within notches 18 to define the fulcrum points of the actuating lever for one arcuate segment of the path of movement of the lever as will be more fully explained hereinafter.
  • the lower edge 17 of body 13 carries a centrally located T-shaped lifting element 19 which is bent slightly toward trigger 12.
  • the stem 20 of lifting element 19 extends. through an opening 21 defined by a pair of aligned notches formed along the interface between the inner edges of hinge plates 2, 3. As best seen in FIGS.
  • the cross piece 23 of lifting element 19 engages the undersurface of hinge plates 2, 3 at a point which, in order to provide adequate leverage, is located longitudinally inward of the pivot axis of the actuating lever during movement of the hinge plates from the outwardly bowed position to the inwardly bowed position; this pivot axis being defined by an imaginary line extending between the fulcrum points which, as previously mentioned, are defined by the points of contact between corners 14b of leg elements 14 and hinge plate notches 18.
  • the lower edge 17 of body 13 also carries a pair of lug elements 24 which are bent slightly toward trigger portion 12.
  • One lug element is located on one side of lifting element 19 at a point located approximately midway between it and the respective leg element on that side of the lifting element; the other lug element being similarly situated on the opposite side of the lifting mem ber.
  • Lug elements 24 engage the upper surface of hinge plates 2 and 3; the points of contact therebetween defining the fulcrum points for the lever for another arcuate segment of the path of movement of the lever.
  • the points of contact between lugs 24 and the hinge plates define the lever fulcrum points in moving the hinge plates from their inwardly bowed position to their outwarly bowed position and in locking the hingeplates in their outwardly bowed position all of willbecome abundantly clearin the following portion of the specification which describes the operation of the binder mechanism of this invention.
  • the body 13 of the actuator portion of the actuating lever is forcibly pivoted inside the case with its upper surface 16 slidably engaging the undersurface of the case and with the lugs 24 engaging the hinge plates.
  • the pivot axis of the lever during this movement is defined by an imaginary line extending through the points of contact between lugs 24 and the hinge plates.
  • the compressive stress is released as the hinge plates move through the coplanar position whereupon the hinge plates pivot with a snap action sharply outward under the force exerted by the case returning to a semi relaxed stage until they are stopped in their outwardly bowed position as the respective ends 2a, 3a of the aligned prong pairs 2', 3 are brought into contact with each other.
  • the body of the actuator portion is freely seated inside the case at about a 45 attitude as shown in FIG. 7.
  • freely seated it is meant that it is not uncommon to find some looseness or play in the actuating lever when it occupies this position.
  • the prong pairs 2, 3' With the actuating lever in the 45 position, the prong pairs 2, 3' are closed. Although in this position they are closed together relatively tightly, there is nevertheless some danger that the hinge plates may be inadvertently jarred back to their open or inwardly bowed position should the binder be accidently dropped. There is also some danger that the weight of the loose-leaf sheets held on the closed prong pairs may be sufficient to pry them slightly apart or possibly cause the hinge plates to snap back to their inwardly bowed position. The latter possibility becomes more likely when the binder is stored in inverted position such that the loose-leaf sheets hang from the prongs.
  • the prongs may be locked in closed position. Locking is accomplished simply by moving the trigger 12 inwardly through a sufficient angle beyond the 45 position shown in FIG. 7 toward the center position shown in FIG. 7b into, say, the position shown in FIG. 70. Referring now to FIG. 7c, in this wedged-in position the major portion 16a of the upper surface 16 of body 13 is in tight surface-to-surface engagement with the undersurface of the case; the remaining or minor portion 16b of upper surface 16 contacting with relatively slight pressure the undersurface of case 1; and the lugs 24 are disposed in tight engagement with the hinge plates.
  • an imaginary line e.g. line 40 interconnecting any point of contact between the lugs 24 and hinge plates and any point of contact between upper edge 16 of body 13 and the undersurface of case 1 extends at an upwardly inclined attitude in a direction (indicated by arrow 41) extending longitudinally outward relative to case 1.
  • any point of contact between the major portion 16a of upper surface 16 of body 13 and the case 1 lies longitudinally outward of any point of contact between lugs 24 and outwardly bowed hinge plates 2, 3.
  • the trigger 12 With the lever in the past-center position shown in FIG. 70, the trigger 12 is disposed at the position and the section 15b of retaining member 15 is disposed in engagement with seating surface on case 1.
  • the lever is thereby prevented from being inwardly pivoted further by an accidently applied force in the direction of arrow 43 into a position where the body 13 would cease to be wedged between the case and outwardly bowed hinge plates.
  • a relatively large force would be required to move the body 13 back through the center position and out of wedged-in relationship between the hinge plates and case.
  • the fulcrum points for the lever are defined by the points of contact between lugs 24 and hinge plates 2, 3. Asmentioned previously the lugs are bent relative to body 13 of the lever actuating portion. This construction achieves the proper positioning of the contact points between upper surface 16 of body 13 and case 1 relative to the-contact points between lugs 24 and hinge plates 2, 3 as previously discussed to provide the unique and novel past center safety lock feature in a ring binder constructed according to this invention.
  • the lock is first released by moving the trigger back to its loosely seated 45 position. Then, the triggers at each end of the case are pressed into the horizontal position. Such movement causes the lifting element 19 to be pivoted into engagement with the underside of the hinge plates 2,.3 thereby moving them through the coplanar position and into the inwardly bowed position in the same manner and with the same motion as described above in connection with closing the prongs by moving the hinge plates from the inwardly bowed position to the outwardly bowed position.
  • the lugs 24 disengage hinge plates 2, 3 and the lever is pivoted about fulcrum points defined by the points of engagement between corner 14b joining legs 14 with the lower edge 17 of body 13 and the notches 18 in the hinge plates.
  • the looseness or play in the lever at the 45 position is accounted for by the shifting of the lever from the fulcrum points defined by the points of engagement between lugs 24 and hinge plates 2, 3 to the fulcrum points defined by the points of engagement between corners 14b and the hinge plates 2, 3 previously described.
  • a loose-leaf binding mechanism whcih includes an elongated spring case, a pair of relatively stiff but resilient elongated hinge plates pivotally mounted within the case, the outer longitudinal edge of each plate defining its pivot axis with the inner longitudinal edges of the plate disposed in abutting relationship for all angular positions of the hinge plates, at least one prong on each hinge plate projecting externally of the case with each prong on one hinge plate being positioned in alignment with a prong on the other hinge plate, and actuator means for moving said hinge plates between a prong-closed position wherein each pair of aligned prongs form a substantially closed loop for retaining loose-leaf sheets and a prong-open position wherein each pair of aligned prongs are spread apart to permit insertion and removal of loose-leaf sheets, the improvement wherein the actuator means comprises:

  • lock stop means capable of preventing pivotal movement of the lever member inwardly out of wedged-in engagement between the case and outwardly bowed hinge plates, said stop means includi. a stationary seating surface mounted on the case in the path of movement of said lever member which surface is along the centerline of the case and a substantial distance to either side of the centerline; and
  • a retaining element mounted on said lever member for engagement along the centerline of the case and for engagement a substantial distance to either side thereof with said seating surface upon movement of said one portion of the lever member into said second wedged-in position;
  • said case being transversely arched with the crown of the arch facing up and said one portion of the lever member including a transversely arched body conforming generally to the curvature of the case with its crown extending generally inwardly or upwardly depending on the angular position of the lever member, said body having a lower surface and a transversely arched upper surface conforming generally to the curvature of the case, said lug elements depending downwardly from the lower surface with one lug element positioned on one side of center and another lug element positioned on the other side of center with each lug element extending into engagement with one of said hinge plates, said upper surface engaging the case and the terminal ends of said lugs engaging the respective hinge plates at all wedged-in angular positions of said one portion of the lever member.
