1 Claim.
This invention relates to single ring toggle units for use in loose leaf ring binders. These units comprise a single loose leaf binding ring with a, toggle mechanism associated therewith to give a snapping action desirable in opening and closing the ring.
A primary object of this invention is to effect a saving in the amount of metal used in the loose leaf binder. During the present national emergency the supply of metal available for manufacturing purposes is limited and is likely in the furture to be more sharply curtailed especially with regard to non-defense industries. Consequently my invention is directed to eliminating metal parts of the binder and at the same time preserving an efiicient binding ring action.
In loose leaf binders it has heretofore been a common practice to provide a cover or spring plate extending the full length of the back portion to which are hinged the cover members of the binder. This cover plate conceals a toggle mechanism operating the rings which are two or more in number, as desired. Generally, however, th cheaper type of binder has but two rings located one at each end of the back portion. According to my invention I propose to eliminate the need for the metal cover plate and to this end I may provide a wood, fiber, or plastic ring toggle back panel strip in which two or more single toggled rings may be incorporated for notebooks in which a plurality of rings may be inserted as desired.
With this and other related objects referred to in the following disclosure I will describe the mechanism of my invention in connection with the accompanying'drawing in which:
Fig. 1 is a bottom plan view of a back panel strip with two single ring toggle frames, one adjacent each end of the panel strip; and
Fig. 2 is a section on line 2-2 of Fig. 1.
In Figs. 1 and 2 I have shown the single ring toggle frame assembled in a casing strip 30 composed of wood, hard fiber, or plastic. Adjacent each end of the strip slots 3| are cut for the passage of the ring halves 2 and hollowed spaces 32 are scooped out of the material of strip 30 to accommodate the toggle wires. As will be seen, since the formation of the wires is such as to make possible a toggle action by the spring pressure of the resilient wires themselves, the nonresilient material of the strip 30 will not impair the efficiency of the snap action. As seen in Fig. 2, provision need only be made to insure that the wires fit snugly in the casing strip and that the hollow portions are generally arched in cross-section. To this end the side edges 33 of hollow 32 have been cut to form a groove, and as shown the hollow is arched.
The structure shown in the drawings will enable the manufacturer to make good appearing and satisfactory binders with great economy by the saving in metal. This binder made with the single toggle frame will be of lighter weight, will have efficient toggle action for the rings, will be provided with back panel reenforcement, and will have all th fine appearance of the customary binder after the paper sheets are put on the rings.
I claim:
In combination with a single ring wire toggle frame, a relatively rigid toggle case strip having a portion of its under side scooped out to form a hollow space in which to nest said wires, slots in the edges of said strip adjacent the hollow portion, said portion being formed with grooves in opposite edges thereof, said toggle fram having the ring halves passing through the slots to overlie the surface of the strip and portions lying in said grooves, said wires having resilient extensions bent towards each other in U-shaped form so that portions of the wires lie in bearing contact with each other to form a toggle joint, the hollow portions of the strip being arched in cross-section to allow the pivotal action of the toggle joint.
JOHN SCI-IADE.
