A folder having at least one paper binding fixture affixed to it. Further, the paper binding fixture can be capable of being opened and closed such that when opened sheets of paper can be placed on a male protrusion and when closed the sheets of paper can be bound by releasably coupling the male protrusions to a female opening. Further, the paper binding fixture can have enhanced safety benefits that substantially reduce the risk of injury to a user. Also, the paper binding fixture can reduce the risk of tearing sheets of paper bound by it.

A binding system, employing a first plastic elongated strip with spaced integral studs and a second plastic elongated strip having similarly spaced apertures and recesses, is provided which resists impact forces caused by dropping a bound book. A first fixed spacing of studs is provided along a mid-span portion of the first strip and a second fixed smaller spacing of studs provided at both end portions of the first strip which reinforces the end portions against stud breakage or extrusion caused by impact forces. In the preferred embodiment, the three end studs at each end of the strip are spaced at a second fixed spacing distance stud center-to-center of only one-half the first fixed spacing at the long mid-span portion of the strip. In another embodiment, a generally second fixed spacing of one-third the mid-span spacing with the at least two of the end portion studs being staggered from the center longitudinal axis of the strip is shown. An additional embodiment includes one or more integral studs of the end portions of the strip having a substantially greater cross-sectional area than the studs in the mid-span portion of the strip. In each embodiment, the binding is end reinforced against impact forces.

A paper sheets binder has a pair of elongated strips, one strip mounting a number of spaced integral hinged pawls and the second strip mounting a corresponding number of spaced integral bifurcated ratcheted posts. The strips are mounted on front and back margin edges of a paper sheets stack. The ratchets on the post legs of one strip connect with pawls on the other strip. To prevent disassembly of the bound document, the preferably D-shaped in cross-section post legs are oriented so that the end posts have a major axis parallel to the longitudinal axis of the strip. Breakage at the root of the post legs is essentially prevented upon bowing of the document and strips, and from shear forces resultant from slippage of the paper sheets and the force generated by the shifting edges of the paper punch holes. The central post is oriented so that the legs major axis is transverse to the strip longitudinal axis. To minimize document gutter width and aid in opening the bound document fully to allow flattening against an image copier platen, the respective integral pawls and posts are offset from the central longitudinal axis of the strips. A counterbore is included around each pawl so that upon snapping-off excess lengths of post legs, the roughened remaining ends thereof are recessed below an outer surface of the pawl-carrying strip.

A paper binder or holder for retaining loose leaf paper sheets, folders, technical bulletins, advertisements and the like in assembled and stacked relation. The device includes a bottom or base strip having a plurality of upstanding pegs integral therewith and which are arranged in spaced parallel relation and provided with peripheral serrations. The pegs extend through apertures in the edge of the paper sheets and also extend through apertures in a clamping bar or strip which engages the upper surface of the top paper sheet. Each aperture in the retaining strip has a tongue which engages the peg by engaging under the serrations to lock the clamping bar in clamped position against the top paper sheet. The entire device is constructed of plastic to enable the cost of manufacture to be retained at a minimum.

A data binder having compression bars forming longitudinal rails and a center channel, flexible posts securing data sheets between compression bars and a retaining slide member embracing the rails to hold the bent over posts in place. Each end of said retaining slide member includes a flare at the end of the center groove for receiving the post. The guide groove facilitates insertion of the post into the retaining slide member.

The invention relates to a securing device conventionally used in conjunction with a sheet material binder system for securing one or more binder strap relative to the securing device, to secure a number of sheets of material together. The securing device has a channel section body portion in which a binder strap is receivable via an aperture in the securing device and a clamp member extending integrally from the body portion and being pivotally displaceable to clamp the binder strap in position within the body portion, a locking means being provided to lock the clamping member relative to the body portion. The securing means may be a double securing means having a single body portion and two clamping members extending integrally therefrom at opposite ends and two apertures through which binder straps can pass to be secured within the body portion by the clamping members. The invention thus also extends to a binder system including such a securing means and to a method of forming such a securing means which includes moulding the securing means as an integral unit in a single moulding operation.
