Abstract: A binder clip having flexible sidewalls biased to close around a rigid retainer for securing pages wrapped around the retainer or pinched by the binder clip and retainer for manually forming a book.

Abstract: A ring binder mechanism for retaining loose-leaf pages securely holds closed ring members together to prevent inadvertent loss of pages retained by the mechanism. The mechanism comprises a housing supporting two hinge plates for pivoting motion to open and close paired ring members mounted on the plates. Free ends of the paired ring members have interlocking configurations that securely join together when the ring members close. The configurations prevent misalignment of the closed ring members in all directions transverse to longitudinal centerlines of the ring members. The mechanism also includes locking elements that interact with the hinge plates to block their pivoting motion when the ring members are closed. This holds the free ends of the closed paired ring members together so that the interlocking configurations of the ring members remain interengaged.

Abstract: Placing sheets around a retainer or between a retainer and clamp and securing a clamp against the sheets and retainer for compressively fixing the pages against the retainer.

Abstract: A quick-release capture mechanism for loose-leaf binders. Generally, the capture mechanism comprises binder posts and a retention clip that selectively and releasably attaches to a free end of the posts. The posts often comprise a tubular section and a post head with a recess defined between the two. In some cases, the retention clip is a rail having a plurality of elongated apertures that are configured to slidably and releasably engage with a plurality of posts, simultaneously. The apertures can have any suitable characteristic. For instance, the apertures can comprise a first width, a second width, and means for retaining a binder post within either the first or the second width. In such instances, while the first width is sized to allow the post head to be inserted perpendicularly therein, the second width is sized to receive the post's recess while preventing the head from passing perpendicularly therethrough.

Abstract: A modular locking binder system is disclosed having a channel is coupled to the binder spine. The channel has an open end and a constricted region. A channel block is located at the open end of said channel and is configured to block and unlock the channel opening. The modular locking binder system is configured to removably hold a document module within the channel. The document module includes a module spine having a widened portion configured to operatively engage and be restrained by the constricted region of the channel. By either obstructing or un-obstructing the channel with the channel block, it is possible to removeably secure the document module within the channel when the widened ends of the document module are operatively engaged and restrained by the constricted portions of the channel.

Abstract: A binder for filing tools which binds sheets having a plurality of sheet hole parts aligned in the center includes a locking bar which corresponds to a front cover wherein two front cover parts formed from flat boards of which one side of each is respectively connected to a back cover part and integrated. The back cover part includes a plurality of key-shaped locking parts erected on the front surface thereof, the key-shaped locking part is penetrated through the sheet hole parts in the sheet, a plurality of tying parts are provided in the locking bar in positions corresponding to the positions of the key-shaped locking parts, and the sheets are held between the locking bar and front cover by each tying part being locked to the key-shaped locking part.

Abstract: A rotatable locking mechanism used with ring systems that open similarly to the rings of a binder. A ring system has rings each having two ring halves and hinged leaves connected to each other and attached to each ring half respectively. The locking mechanism on the ring system presses against the leaves to prevent the ring halves from opening. A lock for the rings can comprise an Allen screw or a similar rotatable device located at the cover over the hinged leaves of a binder or a flip chart holder. Ideally, the device has a lip or similar raised area so it is not removable from an aperture in the cover of a binder or a lockable flip chart holder. Locking the rings provides security so users cannot take pages out of a binder or a flip chart holder.

Abstract: A adjustable binder apparatus for holding papers or other sheet materials together in a manner that does not concentrate pressure on small areas of the paper. The adjustable binder apparatus includes a main member defining a gap for receiving a portion of sheet materials. A pressure assembly is mounted in the gap of the main member, and is slidably movable in the gap for abutting against a portion of sheet materials when the sheet materials are inserted into the gap. The pressure assembly is releasably securable to the central portion of the main member such that spacing between the pressure assembly and one of the side portions of the main member is adjustable.

Abstract: A storage device for retaining one or more sheet items for access by a user. In one embodiment, the storage device includes a storage device cover having at least front and rear panels. One or more first binding members are associated with the storage device cover and extend through apertures formed in the sheet items to register the sheet items relative to the cover. One or more second binding members are hingedly connected to the storage device cover and preferably operate independently of the front and rear panels of the cover to engage the first binding members. Retained sheet items are able to be moved from a first position lying generally parallel with the rear panel to a second position distant therefrom. In an alternative embodiment, the storage device includes a single panel that carries the first and second binding members.

Abstract: A device for binding together a stack of document sheets and optionally for depositing such a bound stack in a file with a filing mechanism, comprising a base plate to be disposed below the document stack, a cover plate to be disposed on the document stack, at least one flexible binding tongue strip which is fixable and/or fixed to the base plate and whose two binding tongues, for the purpose of binding together the document sheets, are threaded through paired perforations in the document stack and the cover plate and are bent back at the ends on to the cover plate above the document stack, as well as at least one cover rail mountable on the cover plate, including the binding tongue ends, with undercuts on the longitudinal edges for encompassing the longitudinal edges of the cover plate, whereby the cover rail is divided into two in its longitudinal direction, so that the two parts are mountable from opposite end faces on the cover plate.

Abstract: A storage device for retaining one or more sheet items for access by a user. The storage device has a storage device cover including front and rear panels, and contains one or more first binding members which receive apertures formed in the sheet items to register the sheet items relative to the cover. One or more second binding members are hingedly connected to the storage device cover and preferably operate independently of the front and rear panels of the cover to engage the first binding members. Retained sheet items are able to be moved from a first position generally parallel with the rear panel to a second position generally parallel with the front panel. Alternatively, the storage device includes a single panel that carries the first and second binding members.

Abstract: A binder ring mechanism (16) has a plurality of binder rings (18a-18c) for holding sheets of paper. Each binder ring includes a fixed section (20) and a movable section (22). All of the movable binder ring sections are commonly mounted on a bolt (36). A lever arm (52) is attached to one end of the bolt for movement of the lever arm to move the bolt and the binder ring sections mounted on the bolt. The bolt is movably mounted on a cover piece (24) for both rotational and sliding movement of the bolt. A recess (58) is formed in an endwall (56) of the cover piece and the lever arm includes a latch member (60) received in the recess to latch the lever arm in place when the binder rings are closed so to prevent inadvertent movement of the lever arm which might cause the binder rings to open. In addition, the cover piece has flaps (82, 84) extending diagonally outwardly therefrom for storing writing instruments in a ring binder (10) in which the binder ring mechanism is installed.
