Abstract: A foldable and unfoldable pop-up article with a tensioning member.

Abstract: A binder includes a back part disposed between ring parts, each of the ring parts being openable and closable. to constitute a binder. A penetration hole is formed at a portion of the ring parts intersecting with the back part, thereby allowing the binder to expand and contract to a certain degree in a longitudinal direction thereof.

Abstract: A binder for holding documents is disclosed. The binder has a spine with a pair of cover flaps attached to each side of the spine. Attached to the spine is a latching device, also referred to as a locking device, that includes a first retaining member, a latching member, and a second retaining member. The first and second retaining members are parallel to each other and extend perpendicular to a longitudinal axis of the spine. The binder is configured to hold a plurality of document modules, each of which hold a set of documents, which are flexible sheets of material, such as paper or plastic. Each module has first and second ends. The first end is contoured to mate with a portion of an external profile of the first retaining member. The second end attaches to the second retaining member. The latching member moves between a latched position where it engages the first end of the module and an unlatched position where it is not engaged to the first end of said module.

Abstract: On the one surface of a back plate suited to a length-and-width size of a ring binder, hooks serving as an engaging means are formed. The back plate is fixed to the spine surface of the file cover. When the ring binder is pressed against the back plate, the hooks are engaged with the ring binder so that the file cover is mounted on a booklet bound with the ring binder.

Abstract: An accessory for a writing board, a file or the like, characterized in that it at least consists of a holder (4) which can be provided to a file or the like (3) whereby this holder (4) works in conjunction with or can work in conjunction with a binding mechanism (5) of the type comprising elements over which documents (8) that are provided with openings (9) can be threaded on the one hand, and whereby this holder (4) can be manually attached to a file or the like (3) on the other hand.

Abstract: The present invention provides an unitary spine binder which comprises an elongated dorsal hinge bearing pairs of opposing and complementary male and female ring elements having known male fastener and female fastener, respectively. Each pair of ring elements also comprise a concave distal end on one element, and a complementary convex distal end on the other element. When the distal ends of the ring elements are moved towards each other, the male and female fasteners reversibly engage with each other so that each pair of ring elements, in cooperation with the dorsal hinge, forms substantially a ring to secure sheet paper by occupying a pre-punched hole in the paper. At the same time, the concave and convex distal ends also engage, so that the sidewalls of the concave distal end engages the convex distal end to protect the fasteners against disengagement by torsional and lateral forces.

Abstract: A system for binding books includes a flexible binding material in the form of a stud having top and bottom caps. The stud is inserted into signature staples that protrude from the body of the signature to form stud holes. The binding material can be any material that is extremely flexible, including silicone, metals, etc., as long as it allows the signatures to open in a lay-flat manner either at the signature interfaces or in the body of any signature. The flexible binding material can also be used to temporarily bind pre-punched pages of a book by inserting the flexible binding material into the pre-punched holes to facilitate lay-flat opening of the book.

Abstract: A loose-leaf file folder includes two covers, a spine made integrally with the covers, and a plurality of paper-holding sets, each set being formed of a shaft, a paper-holding stem, and a crossbar. The shaft and the stem are integrally made with one of the two covers such that the shaft and the stem are uprightly projected from a margin of the one of the two covers. The shaft and the stem are provided in a top end with a retaining hole. The crossbar is provided at two longitudinal ends with a retaining arm and is detachably joined with the shaft and the stem such that the two retaining arms of the crossbar are retained respectively and removably in the retaining holes of the shaft and the stem.

Abstract: A book structure having front and back covers bound together along a spine, with pages therein being secured to the back cover by a binder mounted exclusively upon the back cover, separate and apart from the spine.

Abstract: A ring type binder for perforated sheets or the like in which two members are coaxially secured so that a slot is formed along each longitudinal edge of the members. Another partially open ring member is provided that is configured to be slidably received in the slots so that ring member may be moved from an opened to a closed position. A locking device is provided so that the binder may be selectively locked in the closed portion, thereby preventing the unwanted shifting of the members.

Abstract: In manufacturing a yoke for an elastic universal joint, the time required for each step is shortened and the automation of each step is made easy, and by the energy saving and high efficiency of the manufacturing work, a reduction in the cost is achieved. A metallic plate is subjected to working which can be done easily and within a short time by press work such as stamping work, deep drawing work and ironing work, to thereby make a yoke for an elastic universal joint. This can be accomplished because welding work and cutting work which require much working time and which are cumbersome to automate can be eliminated. Investment in facilities may be small.

Abstract: An adhesive bound pad of paper such as loose leaf binder paper is provided which is secured in assembly by adhesive material, lining or partially lining holes along selected edges of the paper stack forming the pad. The edges of the paper pad remain free of adhesive material and thus are not distorted upon separation of the sheets from the pad. The adhesive bound pad is manufactured by assembling a selected number of sheets of paper into a stack and drilling or otherwise forming holes, such as binder holes, along one of the edges of the stack. Thereafter, the coating of adhesive material is applied within the holes of the stack so as to entirely coat the paper at the holes or to coat selected portions of the paper at the holes as desired. After the adhesive material has been allowed to cure or has been cured the paper is releasably retained in adhesive bound pad form and the manufacturing process is complete. Individual sheets of paper may be pulled away from the pad.

Abstract: A Direct Access Modular Binder containing one or more posts. Each post is comprised of two or more interconnected independent locking modules. These locking modules can easily be inserted or removed to change the length of the post to efficiently accommodate varying amounts of paper. The modules additionally function to permit direct access for insertion/removal of pages or modules anywhere along the post. The modules in the post may contain a telescoping feature. The module(s) containing a telescoping feature are optimally positioned at the end(s) of the post and fixedly attached to the post holding strips. The strips, which hold the posts' ends, may be hingedly attached to the front and back covers. The telescoping feature permits the binder to be automatically compacted (when not in use), for efficient storage, and temporarily expanded (when in use), to provide space for the user to insert/remove paper or modules. The modules which make up the post are easily locked and unlocked.
