Paper 3 is secured within the binder and to section I by rings mounted on section I passing through marginal holes provided in the paper. The rings are arranged in parallel order and each comprises two separable posts 4 extending upwardly and curving to meet at the top. The lower end of each post 4 is welded or secured to corresponding parallel strips 5 and 6 disposed flat against the inner side of section I and adapted selectively to be placed edge to edge to close the posts or rings 4 at the top or relatively separated to open the rings. Strips 5 and B are connected by two sets of spaced parallel links I which maintain the strips in parallel alignment.

Each of the pairs of links i is disposed above and below strips 5 and 6 and pivotally connected thereto by pins 8. Each pair of links is secured to section I by a pivot post 8 extending vertically I the 4 section I and 'Recesses I 0 along the adjacent edges of the strips bindeni t be c i e between strips 5 and 6.

The base to which the bindei istojbesecured is itself secured yifithih the brief case willbe described. "The base comprises} flat se niflexible board 2| having afabric coverifigf22.

Two-edgesof the fabric, covering'fl are extended along-.one' side oftheboard 2lf inthefornijof a is within the case it provide ahinged connection. The flap 23 should be sewn near and along one edge I! of the center section for pivotal movement of the base along an axis substantially close and parallel thereto.

Two round posts 24 project upwardly from the base and are spaced to register with two cor-- responding holes 25 in the center section I of the binder along the longitudinal center line thereof. An annular recess 26 having a vertical width corresponding to the approximate thickness of strips 5 and 6 is out near the top end of each post. Recesses 21 corresponding to the smaller diameter of posts 24 within recesses 26 are provided in the adjacent edges of strips 5 and Ii to register with holes 25.

Thenbinder is secured to the base and within the case by placing the same on thebase with strips 5 and 6 spaced apart and with posts 24 projecting through holes 25 and between the strips. The binder is then locked to the base by closing the strips to engage the recesses 26 of posts 25.

By opening locking device II and separating the strips 5 and 6 the rings are opened and the binder is also released from its base so that individual sheets of paper maybe replaced in the hinder or the entire binder replaced on its base. Closing of the binder locks the same to the base.

The invention provides a simple effective manner of securing the binder to the base operable by the same mechanism as the binder itself. The invention is adaptable to a wide variety of uses other than that described including applications where the binder is to be fastened to a permanent fixture or holder.

Various embodiments of the invention may be carried out within the scope of the accompanying claims.

I claim:

1. A loose-leaf binder and a base therefor comprising a center ring section for said binder having a pair of laterally separable plates disposed in a horizontal plane edge to edge with corresponding upstanding ring posts disposed to co operate in securing leaves in the binder, said plates having complementary recesses in their meeting edges constituting at least two holes upwardly therebetween, posts extending upright from said base and spaced to register with said holes, and interlocking means operable by the closing together of said laterally separable plates to secure said last named posts within said holes to secure said binder to said base.

2. In a ring post loose-leaf binder having-two separable ring post mounting strips with up standing corresponding ring posts thereon, links pivoted to and joining the strips in a common plane to limit the separation thereof, and means for securing the binder to a base comprising at least one upstanding post secured to said base and extending upwardly between said strips, fastening means to receive said last named post between said strips and provide for interlocking engagement of the same by the strips upon closure of the latter and of said ring posts together to secure said binder upon said base, and a latch disposed to lock said strips together when .closed upon said upstanding posts.

3. In a loose-leaf binder having a center section, ring post mounting strips disposed edge to edge, connecting means pivoted centrally to said center section and pivoted at the opposite ends thereof to the corresponding strips to provide for lateral movement of the strips toward and away fromeach other, and rings for securing the leaves within the binder comprised of two meeting parts seemed, to said corresponding mounting strips,

said'strips being adapted to open and close said rings upon corresponding separation and closing of the strips together, means for securing said binder upon a base comprising posts extending upright from the base and adapted to register with and extend through corresponding holes in the center section of said binder in alignment with the meeting line of said strips, notches in the meeting edges of said strips to register with said holes, and annular recesses at the upper end of said posts whereby the recesses of said posts are adapted to be engaged by the notches in said strips in the closed position and released when in the open position selectively to secure and release said binder upon said base.

4. In a loose-leaf binde having a center section, ring posts mounting strips disposed edge to edge, connecting means pivoted centrally to said center section and pivoted at the opposite ends thereof to the corresponding strips to provide for lateral movement of the strips toward and away from each other, and rings for securing the leaves within the binder comprised of two meeting parts secured to said corresponding mounting strips,

said strips being adapted to open and close said rings upon corresponding separation and closing of the strips together, means for securing said binder upon a base comprising posts extending upright from the base and adapted to register with and extend through corresponding holes in the center section of said binder in alignment with the meeting line of said strips, notches in the meeting edges of said strips to register with said holes, annular recesses at the upper end of said posts whereby the recesses of said posts are adapted to be engaged by the notches in said strips in the closed position and released when in the open position selectively to secure and re- V the binder to said base.
