Abstract:
A ring binder having a binder mechanism with rivets secured to the mechanism. Resilient hanging clips ride on the rivets to permit extension of the clips for hanging the binder on a rack. Clips are retracted for normal use. Clips are removable from the rivets when deformed.

Description:
BACKGROUND OF THE INVENTION 
     Numerous extendable hook devices have been proposed for use in hanging binders (U.S. Pat. Nos. 3,957,321 and 4,323,318 and Canadian Patent No. 973,446). Translatable hanging clips with slots therein have also been proposed (U.S. Pat. No. 4,919,557). However, no fully satisfactory hanger arrangement for use with a ring binder assembly has yet been proposed. 
     SUMMARY OF THE INVENTION 
     Broadly, the present invention comprises a ring binder having resilient hanging clips mounted on housing eyelets which eyelets have clip bearing surfaces. The eyelets depend from the arcuate casing, and engage the binder cover when the binder is assembled. 
     It is a feature that the clips are slideable so that the clips can be extended for hanging. Each clip has a slot with a slit opening at one end so that the clip can be deformed to increase the size of the opening sufficiently to allow the eyelet to pass into or out of the clip slot.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With respect to the figures, loose-leaf binders 8, 8a, 8b, etc. are hung on rack 9 using slidable suspension clips 10, 11 mounted at the ends of each of binders 8, 8a, 8b, etc. Rack 9 includes vertical members 9v, upper horizontal member 9h, and base members 9b. 
     Turning in particular to FIG. 2, each binder 8, 8a, 8b includes a binder mechanism 13, a cover 14 with an inside surface 14i and an outside surface 14, two suspension clips 10, 11, and two rivets 16 to secure each mechanism 13 and cover 14 together. Each mechanism 13 in turn comprises an elongated arched casing 17, two hinge plates 18, 19 and two or more rings 21 formed of ring halves 21a, 21b. Fastener housing eyelets 22 each have upper annular ends 22a, lower annular bearing ends 22b and round bearing stem portion 22c. The outside surface of stem 22c may be non-round provided it has curved or angled surfaces for enlarging slit opening 20 when force is applied. Upper eyelet ends 22a are secured by welding or otherwise to and depend from the underside of casing 17. 
     Binder cover 14 has base portion 14a, hinge 14b, top cover portion 14c and an aperture 14d in portion 14a. Rivets 16 which are housed in eyelets 22 include outside head 16a, stem 16b and deformable head 16c. Upon assembly and deformation of rivet head 16c, eyelets 22 and rivet 16 form a fastener assembly for holding together in spaced-apart relationship the cover 14 and arcuate casing 17. Clips 10, 11 are slidable mounted on head 22b and stem 22c between cover 14 and mechanism 13. 
     Turning to FIGS. 3, 5 and 6, each clip 10, 11 is made with plastic or other resilient material which when deformed restores itself to its original position and each clip 10, 11 includes outside bottom planar body portion 27 with a slot 28 extending vertically through body portion 27 which slot 28 includes outside end 28a and inside end 28b, which inside end 28b is split by slit opening 20. Opening 20 is normally narrower than the width (or diameter) of stem 22c but can be enlarged to allow stem 22c to pass therethrough. The length of slot 28 determines the length of clip travel which travel or reciprocation is limited by slot ends 28a, b engaging stem 22c. Bearing stem 22c bears on the sides 28s of slot 28 as clip 10 reciprocates. Clip portion 27 consists of two planar portion halves 27a, 27b. Each half 27a, 27b has recessed areas 29a, 29b respectively to accommodate heads 22b of eyelets 22. Each planar half 27 a, 27b also includes sloping pointed inner prong portions 30a, 30b which can be deformed to spread apart to increase the size of slit opening 20 to allow bearing stem 22c to pass through for assembly and disassembly of clips 10, 11 on and off eyelet stem 22c. Clips 10, 11 also include curved wall portions 32a, 32b adjacent portion 27 which walls have ridges 33 therein to assist in gripping by the binder operator&#39;s hands. Each curved wall 32a, 32b also has rack-engaging lips 35a, 35b respectively. 
     Finally, turning to FIG. 4b, slidable clip 10 is shown extended until eyelet 22 engages slot end 28b and in FIG. 4a clip 10 is shown retracted. Also shown in FIGS. 4a, 4b, is trigger 37 of binder mechanism 13.
