It is an object of this invention to provide a case member with means whereby a ring metal may be readily attached or removed from the case member. vention to provide simple and eificient means t is a further object of this infor maintaining a ring metal in a case member.

Other objects of this invention will become apparent upon reading the following description, taken in conjunction with the accompanying drawings, in which:

Figure l is a fragmentary prospective view of a case member with a ring member in disassembled position;

Figure 2 is a longitudinal sectional view through the center of the binder showing the ring metal secured in one position;

Figure 3 is a view similar to Figure 2 showing the ring metal secured in reverse position; and

Figure 4 is a cross sectional view taken along the line IV-IV of Figure 2'.

In the drawings, the reference numeral-2 indicates a back member to which a pair of cover members 3 is suitably hinged. A back plate a is secured to' the back member 2 by means of a plurality of rivets or eyelets 5. The plate 4 is provided with a pair of elongated apertures 6 and l.

The aperture 6 is provided with an end portion 8 of reduced width, and a raised flange 9 around the reduced portion. similar to the aperture .5 except that it is provided with an upstandin projection ifi at the The aperture 1 is.

end of the wide portion of the slot. The flanges 9 form a raised channel member at corresponding ends of apertures E 'The plate l is also provided with an aperture H spaced from the aperture 6 a distance approximately equal to the length of the'aperture 5. The aperture i! is provided with an upstanding flange or wall The ring metal it includes a cover plate 14 in which a pair of toggle plates l5 is arranged in s de by side relationship. The longitudinal edges of the cover plate are bent inwardly, as indicated at hi, to embrace the outerledges of the toggle plates and to provide the necessary spring force whereby the toggle plates are maintained in either of two positions. have mounted thereon a plurality of meeting ring'sections I! which remain open when the The toggle plates toggle plates are in one position, and form closed rings when the toggle plates are in their other position. A trigger [5 may be provided at the end of the ring metal to facilitate manipu- V lation of the rings. I

Studs I9, secured to the under side of the cover plate i i, are spaced apart a distance equal to the center to center distance between the elongated apertures 6 and l. with a head 25 and 'a reduced neck portion 2|. When the ring metal :3 is superimposed on the back plate '2 each stud registers with one of the aperturesfi or E, and 'a sliding movement toward the narrow ends of the apertures-6 and 7 causes the neck portion 2! 'of each studto'engage the raised flange 9. The head 20 of each stud engages the otherside ofthe flange; 9 to prevent vertical movement of the ring metal rel-V The toggle plates I 5 ative to the back plate. are recessed, as indicated at 22,.to provide clearance space for the studs 18.

Whenthe ring metal the back plate d, with the studs l9 engaging flanges at the reduced ends of the apertures 6 and l, a screw 23, threaded in the cover plate, maybe screwed down'to engage either the'flange 2-or the raised portion i F3, depending on whether the rinmetal is in the position indicated in Figure 2 01 that indicated in Figure 3. The toggle plates 15 are recessed, as indicated at 24, to provide clearance for the screw 23. By its engagement with the flange l2 or the raised portion it, the screw 23 effectively prevents sliding ring metal would still be obtained, provided a positionedat the same similar aperture were distance from the plate 4. In this case the upstanding projection l9 would have no function and could be omitted. If the ring metal were provided with any. number of rings permitting V a space to be left at'the center of the ring metal,-

the screw 23 might be positioned there, and a single aperture H would be suflicient. The projection Ill could be omitted in this case also.

Although Ihave described a preferred embodiment of my invention in detail, it will be understood that the description thereof is illustrative, rather than restrictive, as many de tails may be modified or changed without de- Each stud is provided is positioned adjacent metal cannot be separated parting from the spirit or scope of my invention. 1 a

, Accordingly, I do not desire to be restricted to the exact constructiondescribed, except as limited by the appended claims.

I claim:

1; In a loose leaf binder, a back plate provided with a pair of elongated apertures having raisedflanges adjacent one end thereof, said back plate being provided with another aperture spaced from one of said elongated apertures a distance approximately equal to the length of said aperture, said other elongated aperture having a raised portion adjacent its end opposite said raised flange, and a ring metal provided with a pair of studs engageable with said raised flanges and a screw engageable with said last mentioned tions when said ring metal is in one position and aperture when the ring metal is in one position with said other projection when said ring metal is reversed, and a screw engageable through said 'last mentioned aperture with either projection to prevent accidental separation of said ring metal from said-back plate.
