or in any way interfering with the plates.
particular disclosure, all and broad scope of the changed as regards this within the true intent claims.
Fig. l is a plan View of a complete loose leaf binder metal incorporating features of the invention, showing the rings in closed position.
Figs. 2 and 3 are enlarged broken longitudinal sectional views showing the parts respectively in the ring closed and ring open positions.
Figs. 4 and 5 are crosssectional details on lines ll-il and 5-5 of Fig. 2, illustrating relation of the ring closing trigger and the ring opening trigger respectively in the ring closed condition of the binder. k
Figs. 6 and '7 are similar views on lines 6 6 andi- 1, Fig. 3, showing the same parts in the ring open position of the binder.
Fig. 8 is 'a perspective View of the ring closing trigger or lever. l
The binder illustrated consists in general of a spring back plate I l), having inturned edges II, forming channels in Which are engaged the outer edges of the toggle plates I2, carrying the companion ring elements, hooks or prongs I3, the latter operating up through slots Ill,` in they edges of cover plate l5, which is closed down about the edges of the back plateat I6.
The ring opening trigger is designated II, at the right hand end of the binder metal, Figs. l, 2 and 3 and the ring closing trigger is designated I8, at. the opposite left, handv end of the structure. The exposedxportionsiof the.- two; trig- (Cl. L29-24) gers, for the sake of symmetry may be alike as indicated in Fig. l, or if desired, particularly for provide a smooth top lever portion with substantially parallel sides I9.
The ring opening trigger I1 is shown as having in the end of the toggle plates, between the end lugs or tongues 23. having a deeper notch 26, at ,the folded portions of the lever forward of the cross bar 2|.
movement of the trigger, will prevent the trigger .from dropping back oi the end of the plates.
closed and the toggle plates 25., 2S, in the end of the toggle plates provide clearance, enabling these plates to rock upwardly from Vthe lowermost (Fig. 5) to the uppermost positions (Fig. 7) even rthough the cross bar of the trigger actually rocks at 22, over the upper outer edge portions of the plates. Thus while the trigger is supported on top of the plates, the clearancenotchesin the ends ofr theplates enable 2 the latter to swing freely up and down past end of the trigger.
The ring closing trigger I8, like the opening trigger l1, is simply loosely engaged over the ends of the toggle plates and has portions engaging the edge and intermediate portions of the plates at opposite sides of the same. The parts which engage the edge portions of the plates however, engage them at the underside and the parts engaging the intermediate portions of the plates engage them at the upper side, thus to enable such closer to rock the adjoining edge portions of the plates downwardly in the ring closing direction.
In the form here shown, the substantially parallel sides I9 of the closing trigger are arched at 29, to oveistand the reduced width tongue portions 30, on the ends of the toggle plates, the sides 3|, of such arch projecting downwardly through the slots or notches 32, in the ends of the plates and carrying at the forward end of the trigger lateral extensions 33, engaging beneath the edge tongues 34 of the plates. rIhese sides of the arch also carry at an intermediate point in the length of the trigger, the inwardly struck lugs 35, which engage beneath the end tongues 3U, on the central portions of the plates, thus to enable the plates to retract this lever as they move downward in the ring closing direction.
The closing trigger, like the opening trigger, is not caught or secured to the plates, but is merely held loosely engaged over the ends of the plates by having the folded down sides of the same operate loosely in a confining and guiding slot 36 in the cover plate i5.
In the closed position of the rings with the toggle plates rocked downwardly, the closer is in the lowered position, Figs. 2 and 4. When the openei` rocks the plates upwardly, the center tongues 3l), engage the underside of the arch 29, which may be inclined as indicated in Fig. 8, thus to lift the closer to the upstanding inclined position shown in Fig. 3. In this raised relation, the closer indicates by its position that this is the trigger to be depressed to effect closing of the rings. Downward pressure on this raised trigger causes it to rock on lugs 33, against the under edge portions 32, of the plates and to press with lugs 31, back of the inclined arch 29, downward on the central tongue portions 3i) of the plates, thereby to rock the plates downwardly and close the rings.
The toggle plates or bars, except for notches in the ends of the same, may be of the usual construction. The trigger levers are assembled by inserting the handle portions up through the guide slots 23, 3S, in the cover plate and then placing the cover over the toggle plates, so that the levers will drop endwise into the notches in the ends of the plates, with the transversely projecting lugs 22 and 33, engaging over and underneath the edge portions of the plates and intermediate lugs or hooks 21, 35, engaging beneath the central portions of the plates. The cover can then be flanged down about the back plate to retain the parts in such relation. This method of simply engaging the triggers endwise over the plates simplifies assemblage and leaves the ring carrying plates free to quickly snap open and closed with slight pressure on the triggers. The triggers in this construction need not extend beyond the ends of the cover plate and hence need not add any to the overall dimensions of the ring metal.
Desirable leverage for the the closer is provided in the illustration by the two lugs 31, projecting downwardly from the folded sides, spaced back from the pivoting axis 33, at the forward end of the trigger and located to engage the plates close to the meeting edges of the same. Lugs 38 dependent from the folded sides, in back of these closing lugs act as abutments, in the upraised position of the trigger to hold it confined in the guide slots.
