Definitions

• the present invention belongs to the field of bookbinding and requisites for clipping and storage of documents, i.e. among requisites adapted for sorting and organizing documents, especially of such kind, which comprise corresponding means for inserting through appropriate openings, by which the stored documents are furnished, namely among two- part clipping assemblies, which includes a stable part having at least two stable pins, as well as a pivotable part, which also includes at least two pivotable pins.
• the background of the invention represents a file mechanism, which comprises a base plate having two stable pins firmly attached thereto as well as a clamping set, which is actuated by means of appropriate lever and comprises two pivotable pins, which are firmly interconnected to each other by means of an intermediate section, which is supported by a spring, and may be pivoted and pressed towards the stable pins on the basis of swiveling said lever.
• the purpose of the proposed invention is to assure a still greater angle between the stable pins and pivotable pins by opening the mechanism, and at the same time that the lever in the disengaged state of said pin would be placed in such a position that transposition of sheets stored in the document file would be possible, by which a reliable operation of such mechanism would have to be assured by minimum possible modifications of the existing construction concept of such a file mechanism and if possible on the basis of incorporation of the existing base plate together with the existing clamping set at least as semi-products used in manufacturing of such products. If such problem could be successfully re-solved, then the invention could be realized promptly and with minimum financial assets, which are otherwise required for the purposes of development and manufacturing of working tools and other manufacturing accessories.
• a mechanism is described in GB 815,108, by which a pair of apart from each other arranged stable pins is foreseen on the base plate, which is adapted to cooperate with another pair of pivotable pins, which are interconnected via appropriate section and together form a clamping set, which is by means of appropriate bearings pivotally attached to the base plate.
• a cantilever is foreseen on the base plate in the form of cutout, which is bent approximately perpendicularly with respect to the main plane of said base plate and to which then a swiveling lever of an actuating handle of the document file is pivotally attached, wherein said handle is pivotally attached to a further bearing, which is available on the base plate.
• Said actuating handle is therefore on the one hand pivotally attached to the base plate by means of the lastly mentioned bearing, and on the other hand pivotally connected with the swiveling lever, which is pivotally attached to the cantilever and furnished with appropriate pressing means, which is rest on an eccentrically shaped central portion of the intermediate section of the clamping set. Still further, there is a recess in the central area of said swiveling lever, into which an arresting element is protruding, which is intended for the purposes of maintaining the swiveling lever in each corresponding position, when the handle of the mechanism is pressed opposite to the force of said spring towards the base plate and the mechanism is closed, so that each pivotable pin is pressed towards each corresponding stable pin.
• Such mechanism consists of a plurality of components and is therefore really complicated and problematic when bearing mind reliability thereof.
• Such mechanism consists of a base plate, on which a pair of stable pins is available, which are firmly connected to said base plate, and moreover a pair of pivotable pins, which are interconnected by means of a rigid intermediate portion and are therefore simultaneously pivoted by means of appropriate lever, which is pivotally connected to the cantilever, which is arranged in the central portion of said base plate and represents a part of said base plate or is firmly interconnected therewith.
• the base plate includes appropriate reinforcing elements as well as openings adapted for attachment to each disposable file cover.
• Two stable pins are attached to said plate apart from each other and located in both corners of one of both longer lateral edges thereof, and their free ends are bent towards free ends of pivotable pins.
• two pivotable pins are embedded within appropriate bearings and interconnected by means of an intermediate portion, which is bent in a trapezoidal shape essentially in the form of letter U.
• Said bearings are normally placed adjacent to the longitudinal edge of the base plate, while the intermediate section, by means if which said pivotable pins are interconnected, is placed towards the central portion of the base plate and extends essentially parallel to the aforementioned edge of the base plate.
• a cantilever is foreseen approximately in the central area of the base plate, which protrudes apart from the base plate and at least approximately perpendicularly with respect to the aforementioned plane and forms at its free end and apart from the base plate a pivot joint of appropriate lever, which is intended to control the file mechanism and pivoting the pivotable pins with regard to the base plate and the stable pins.
• Said lever is arranged in the vertical plane, which extends parallel to the longitudinal edges of the base plate.
• a roller is embedded on the lever eccentrically at a certain distance with respect to the pivot joint, and is adapted for being rolled along said intermediate portion between both pivotable pins.
• said lever is formed in the shape of the letter L, wherein the longer arm is intended for actuating, on the end portion of the shorter arm said roller is embedded, and the lever is embedded in the coinciding area of said arms.
• the clipping assembly is supported by a spring, which is normally available as a cantilevered bending spring.
• the roller By pivoting the actuating arm of the lever towards the base plate, the roller is moved along the intermediate portion between the pivotable pins, by which said intermediate portion is pressed towards the plane of the base plate in a direction opposite with respect to the force of the spring.
• the roller When the roller is moved across the line, which extends perpendicularly with respect to the plane of the base plate throughout the pivot joint on the centrally arranged cantilever, then the free end of each corresponding pivotable pin is rest on the free end of each corresponding stable pin. Since the lever may be pivoted still further, such movement involves movement of the roller beyond said line, upon which the lever is fixed and arrested in such a state, by which the file mechanism is closed.
• the base plate is despite to a relatively small thickness of the raw material sufficiently rigid and also the clamping set as such is perfectly designed and enables optimum and reliable operation, and also the process of manufacturing the components including subsequently assembling thereof is conceived optimally and is executed in a completely automatic manner, by which the former exploitation of the solution according to EP 1 606 122 is feasible within still acceptable cost limits.
• EP 1 226 987 proposes a generally analogous mechanism, which also consists of a base plate with stable pins firmly attached thereto as well as wit a centrally arranged cantilever, to which a lever is attached in appropriate pivot joint.
• both pivotable pins are interconnected by means of an intermediate section, which is in its central portion pressed towards the main plane of the base plate by means of appropriate roller, which is eccentrically embedded on the lever, and at the same time said intermediate section is pressed away from the main plane of the base plate by means of a spring, which is mounted on the base plate below said central area of the intermediate section.
• a limitation means is foreseen on the base plate below the central portion of the intermediate section between the pivotable pins, by means of which pivoting of the actuating arm away from the base plate is then limited.
• the actuating arm of the lever is then prevented from protruding into the area between the pivotable and stable pin, when positioned apart from each other, which would otherwise make transposition of sheets impossible. Accordingly, thanks to said limitation means the actuating arm of the lever is allowed to be pivoted only in such an extent that even in opened mechanism said arm is still maintained relatively close to the main plane of the base plate and at least at such distance apart from the stable pin and a corresponding pivotable pin, that transposition of sheets is still possible.
