Definitions

  • This invention relates to a loose leaf binder, and is particularly concerned with a post binder having a top post retaining member adapted to hold and conceal the upper ends of flexible sheet retaining posts, and having a bottom pos-t retaining member shaped to prevent the lower ends of the sheet retaining posts from scratching or marring a desk or other finished surface upon which the binder may be used.
  • the loose leaf binder of the present invention comprises top and bottom post retaining members each having integral hinge lugs along one longitudinal edge, and top and bottom covers hinged thereto.
  • the top and bottom post retaining members have vertically aligned apertures to receive flexible sheet retaining posts.
  • Each post has an enlarged head on one end which is positioned adjacent the lower surface of the bottom post retaining member.
  • the posts extend upwardly through the apertures of the bottom post retaining member to receive the sheets to be held in the binder.
  • the lower surface of the bottom post retaining member is concavely curved in the transverse direction to provide clearance for the heads of the posts to prevent them from coming into contact with the surface on which the binder is handled.
  • the top sheet retaining member rests on the sheets impaled on the posts, and the upper ends of the posts, which project through the apertures of the top post retaining member, are bent over into a recess in the upper surface of the top member.
  • the length of the recess is coincident with the length of the top member.
  • the depth of the recess is slightly greater than the diameter of the sheet retaining post, so that the position of the post adjacent the aperture of the top member, where the post is bent at approximately a right angle, may be retained Within the recess.
  • the recess is sumciently wide to receive four sheet retaining posts in side by side relationship.
  • Each longitudinal edge of the recess in the top member is provided with a lateral groove of the same length as the recess.
  • the cover plate for retaining the bent upper ends of the sheet retaining posts is provided with a lateral flange on each longitudinal edge. The lateral anges of the cover plate fit in the lateral grooves of the recess to permit the cover plate to slide longitudinally of the recess.
  • the binder may have two cover plates each approximately equal to one half the length of the binding edge of the binder, or it may have a substantially fixed center section and two slidable cover plates at opposite ends of the center section.
  • the top cover plates provide a neat, attractive appearance for the top of the binder.
  • the esthetic appeal of the bottom member is enhanced by curving the upper surface symmetrically with respect to the lower surface thereof.
  • the symmetrical contiguration of the bottom member also enables it to be reversed, so that the sheet retaining posts may be inserted through the apertures of the bottom member in either direction.
  • lnterengaging stop members are provided adjacent each end of the longitudinalrecess in the top member, and at inner end of each cover plate, to prevent complete separation of either cover plate from the top member.
  • lt is an object of this inventionto provide simple and efficient means for holding both ends of a plurality of 'flexible sheet retaining posts tightly against the top andfil@ raies-ted Mar. s, 1953 bottom members of a binder so that sheets mounted on said posts may be securely retained in the binder.
  • lt is a further object of the invention to provide a re cess in the top post retaining member of a binder with a slid-ing cover plate substantially ush with the upper surface of said post retaining member.
  • FIG. l is a perspective view of a loose leaf binder embodying the invention.
  • FIG. 2 is a fragmentary perspective view of the top and bottom post retaining members showing a sheet retaining post in place, but with the top cover plate removed, to facilitate illustration of the top post retaining member;
  • FIG. 3 is a fragmentary perspective view of the top cover plate adapted to hold the upper ends of the flexible sheet retaining posts;
  • FiG. 4 is a fragmentary top plan View of the binder, with the top cover plate removed to show the disposition of the flexible sheet retaining posts in the upper member;
  • FIG. 5 is a cross sectional view, taken substantially along the line 5 5 of FIG. 4, but showing the top cover plate in place;
  • FIG. 6 is a fragmentary perspective View of the top post retaining member, showing the top cover plate holding the bent end of a flexible sheet retaining post;
  • FIG. 7 is a detailed perspective view of the top cover plate in inverted position to show the stop member
  • FIG. 8 is a cross sectional view, taken along the line S-S of FIG. 1;
  • FIG. 9 is a fragmentary perspective view of the top of a loose leaf binder, showing another embodiment of the invention.
  • FIG. l0 is a fragmentary top plan view of the top of the binder shown in FIG. 9, with the top cover plates removed to facilitate illustration of the top post retaining member;
  • FIG. 1l is a fragmentary cross sectional View, taken along the line lli-11 of FIG. 10.
  • a bottom post retaining member 2 which is preferably extruded of any suitable plastic material, is provided with a transverse concave curve -3 on its upper face and a symmetrical concave curve 4 on its bottom face.
  • the concave portions 3 and 4 merge into an outer edge portion 5 of increased thickness and a similar portion 6 of increased thickness spaced outwardly from the inner longitudinal edge portion 7 of the bottom member.
  • Integral hinge lugs 8 extend outwardly from the longitudinal edge portion 7 to receive a hinge pin, by means of which a bottom cover 9 is hinged to the bottom post retaining member 2.
  • a plurality of eyelets ,1d extend through apertures in the central portion of the bottom post retaining member.
  • Each post has an integral enlarged head 12 at its bottom to prevent the post from being pulled entirely through the eyelet.
  • the thick portions S and 6 of the bottom post retaining member proj'- ect below the bottom surface of the enlarged heads 12 ,of the sheet retaining posts, thereby protecting any sur- Aface upon which the binder may be placed from coming Yinto contact with any of the enlarged heads 12.
  • the top post retaining member 13 is also preferably extruded f any Suitable. plastic material, and, has. integral. hingelugs ld'lprojecting from its inner longitudinal edge portion 15.
  • a top cover 16. is hinged to post retaining member 13 in the same manner ⁇ as the bottom cover 9 is hinged to'bottoxn postv retaining member 2.
  • a longi. tudinal recess 17 is centrally disposed along the entire length of top post retaining member 13, and each edge of the recess 17 has a lateral groove 18 or 1,9 extending along the entire length of the recess.
  • the grooves 18 and 19 are each positioned about midway of the depth of groove 17.
  • Aneyelet 20 extends through an aperture in the center portion of groove 17 in vertical alignment with eachV eyelet 10, so that sheet retaining posts 11 extending through eyelet i may also passthrough the eyelet 20.
  • Eachk plate 21 has a permanent stop member in the form ofl an upturnedlip22 on its edge closest to the outer'edge. of the top post retaining member 13.
  • Each off the upstanding lips 22 extends almost, but not quite tothe upper surface of the top post retaining member 13.
  • the stop members 22 are outside the outermost eyelets 20, and therefore do not interfere with the flexible sheet retaining posts 11, which are bent inwardly at right angles vto extend in the recess 17 between the outermost eyelets 20.v As shown in FIG.
  • the width of the recess 17 is sufficient to permit the bent over upper ⁇ end of one sheet retaining post ⁇ 11V to extend past thesheet retainingpost extending through an eyelet 20 spaced inwardly thereof, Without interfering with the longitudinaldispositionof thevfsecondpost.
  • top coverA plates 23, eachhaving a length equal to one halfthelength of topposn retaining member 13, are provided forothe binderwin FIGS. 1- to 8. Since these top cover plates are identical, only one will be described;
  • Thetcover plate 23 compri ses.
  • a flattop wall 24' having a-widthfequalzto.the-widthof the upper-"portion of recess 17, and a pair of depending perpendicular side walls 25 each terminating in alateral.flange 26.
  • Flanges 26 are adapted to t'slidablyiinfthe lateralA grooves 18V and 19.
  • Thelsiderwalls 25 are so dimensioned, thatl when the anges 26 are positioned in the grooves 18 and 19, the top wall24 is substantially ilush with-the upper surface of top post retaining member 13,
  • the top cover plate also has an end wall 27 andadownturned -lip 28.
  • the lip 28 extends across lthe entirewidth o f the cover plate and serves asa fingerpull to 'facilitate sliding movement of the top cover plate relative to the.recess 7;
  • a tab ⁇ 29 at the inner end of top wall 24 is bent inwardly against the underside of the top wall to provide a shoulder Sil-.spaced a short distance from theend of thetop-walL
  • the sheet retaining posts cannotbe bent precisely atright angles, and therefore the recess 17 has a greater-depth than the diameter of the post, as shown ina-FIG. 8. Tlhisclearance also enables the end 2-9 of the top-cover plate 23 to slide over the sheet retainingrposts. The resilience of the sheet retaining posts causes them to exert sullcient frictional force against the underside of top wall 24 to hold the top cover plate 23 in placeV and prevent it from sliding too freely.
  • the top cover plate 32 comprises a top wall, two side Walls and two lateral flanges, all ofwhich are identical toA the corresponding structure of. cover plates 23.
  • top cover pla-te 32 must be less than the distance between the two innermost.
  • sheet retaining posts 11 Th@ ⁇ cover plate 32 is disposed. intermediate the length of recessv 17, and ⁇ thel two outer portions of the recess are each provided with a slidable; top cover plate 23.
