Media binder arrangement (10) comprising at least one spring clamp (15) attached to the spine (14) of the media binder. The spring clamp (15) having an interior cavity (19). The interior cavity (19) of said spring clamp (15) is additionally formed with a datum spacer cavity (35) having spacer walls (36, 37) limited from the sides (16, 17) by a bending. The spacer walls (36, 37) having wall surfaces facing the clamp base (18) for holding the datum spacer (30) in abutment with the clamp base (18). Method of manufacturing such a media binder arrangement (10).

A file folder having front and back covers delineated from each other by a spine therebetween is formed with a pocket located at the outboard edge of at least one of the front and back covers. The pocket has closures at the top and bottom edges and also at the outboard edge of the cover upon which it is formed. The pocket has a mouth that opens toward the spine. At least one lock wing is formed by a patch of stiff material having a fixed portion secured to the cover having the pocket at the spine. The lock wing also has a free portion that extends toward the mouth of the pocket and forms an acute angle with the cover to which the lock wing is secured. Papers, media, or other contents can be inserted into the open mouth of the pocket and the lock wing can be resiliently flexed to receive the inboard extremity of the pocket contents beneath it. The contents of the pocket are thereby securely held in the pocket by the constraints of the pocket closures and the lock wing.

A binder system is disclosed that flexibly secures one or more flat objects including by mechanical grasping of flat-shaped or sheet materials in a central spring clamp having a compact cross-sectional geometry that can adapt to several sizes of clamped materials and uses. The spring clamp comprises an elongated tri-folded spine with a flat central portion and flat side portions, and flat cover supports that are attached by hinged means to the side portions of the spine. The flat central portion aids a user in opening and keeping the system in its open configuration. In some aspects the system includes customizable covers attachable to said cover supports.

Binding element (1) for a bundle of leaves (9), whereby the binding element (1) comprises a spine (2) for enclosing an edge of the bundle (9) and two plastic cover sheets (3,4) fastened to the spine (2), characterized in that a first of the cover sheets (3) is transparent and the second of the cover sheets (4) is translucent but not transparent.

A media binder has an inner assembly and a case assembly, The inner assembly includes inside boards pre-attached to a binding mechanism. Adhesive is placed on outward surfaces of the inside boards. The case assembly includes a cover sheet with at least one marginal edge attached to surface boards and at least one loose edge. To customize cover, a printed cover is inserted in-between the cover sheet and the surface board through an opening formed by the loose edge. The case assembly is then laminated. The laminated case assembly is combined with the inner assembly using the adhesive on the inside boards. A one-piece media binder has cover sheets wrapping around surface boards forming pockets. The surface boards are partially attached to paste downs. To customize cover, printed covers are inserted into the pockets, and the paste downs are then attached to the surface boards to seal loose edges.

A hook-and-loop fastening structure for a clipboard contains: a cover and an accommodation box rotatably connecting with the cover. The accommodation box includes an accommodating chamber, a fixing slot defined on one of two inner peripheral sides of the accommodating chamber, and two opposite insertion portions, wherein each insertion portion is arranged on each of two inner ends of the accommodating chamber. Each insertion portion has a recess and a through hole defined between and communicating with a bottom of the recess and the accommodating chamber. The fixing slot of the accommodating chamber is configured to house a clamper for clamping papers/documents, and a hook-and-loop fastener is connected with the two opposite insertion portions so as to fix an object (such as a mobile device or a tablet PC) in the clipboard, after inserting the hook-and-loop fastener into the recess and the through hole.
