Definitions

• the invention relates to a letter folder made of stiff cardboard material with a file spine, a front cover and rear cover hinged to the file spine and a file mechanism detachably arranged with a base plate on the inside of the rear cover.
• the folder mechanism of known letter folders usually has two line-up pins protruding vertically on the base plate for receiving perforated documents, a transfer bracket which can be pivoted to a limited extent on the base plate between an open position and a closed position, and an actuating lever which acts directly or indirectly on the transfer bracket.
• the folder mechanism is riveted to the back cover at the factory. This means that the folders can be used immediately without any assembly effort.
• the empty folders require considerable storage and transport space.
• the locking takes place there via resilient tongues or resilient embossments protruding from the insert plate. With these measures it is possible to separate the folder mechanics and the bindings separately store and ship.
• the additional insert plate made of metal is, however, very expensive in terms of material and has upstanding latching parts which, in the case of a tight packing for shipping purposes, can damage the neighboring binder bindings.
• the invention is based on the object of improving the known letter folder of the type mentioned at the outset such that the folder mechanics can be detachably attached to the folder cover with as little additional material expenditure as possible.
• the solution according to the invention is based on the idea that the latching mechanism for attaching the file mechanism can be integrated in an opening in the relatively thick cardboard material of the rear cover in such a way that it cannot be moved inwards or outwards over the broad side surfaces of the rear cover survives.
• the binder bindings for storage and packaging purposes can be stacked one on top of the other without the risk of damage by the latching mechanism.

• a preferred embodiment of the invention provides that the locking eyelet is designed as a sheet metal part which is riveted through the opening and has at least partially circumferential edges which are flanged to the outside and at least partially encircled on the inside and outside surface of the rear cover.
• the locking eyelet is designed as a sheet metal part which is riveted through the opening and has at least partially circumferential edges which are flanged to the outside and at least partially encircled on the inside and outside surface of the rear cover.
• at least two locking eyes arranged parallel to one another in their longitudinal extent or on circular arcs concentric to one another and a number of locking elements corresponding to the locking surfaces are provided.
• the latching elements are designed as latching lugs or latching cams which are formed on the base plate, in particular on the edge of the base plate, and are preferably bent out of their base surface facing the rear cover in the direction of the rear cover.
• the latching elements can, however, also be designed as latching cams arranged on the base plate, in particular riveted to it, preferably projecting in the direction of the rear cover over the base surface facing the rear cover.
• the latching surface is formed by an edge region of the latching eyelet flanged on the inside of the rear cover into the inside of the eyelet.
• the edge region of the locking eyelet adjacent to the locking surface is flanged against the inside broad side surface of the rear cover to form a widened insertion opening for the locking element.
• the latching surface has a run-up slope facing the insertion opening and a latching depression for the latching element which follows the run-on slope.
• the locking recess and / or the run-up slope can be formed by simple stamping deformation in the locking surface.
• two latching eyes are provided, which extend in their longitudinal extent parallel to the rear edge of the rear cover and are spaced one above the other, into which the folder mechanism can be inserted parallel to the relevant edge and can be snapped into place.
• a second embodiment variant of the invention provides that at least two locking eyelets which are oriented in the same direction and extend essentially tangentially to a common center of rotation are provided.
• the locking eyelets can be curved in a partial circle in terms of their longitudinal extent with respect to the center of rotation, the locking surfaces being able to be arranged on the radially outer curved longitudinal side edge of the locking eyelets.
• two latching surfaces spaced apart from one another in the longitudinal extent are arranged in a latching eyelet for two latching elements of the base plate engaging in the same latching eyelet.
• the folder mechanism is inserted into the latching eyelets in an oblique orientation with respect to the rear edge of the rear cover and, by rotating about the center of rotation, preferably latched clockwise with its latching elements on the latching surfaces.
• the latching eyelets are oriented transversely or obliquely in relation to the rear edge of the rear cover.
• the locking eyelets can be arranged at different distances from the rear edge of the rear cover, while the locking eyelets and the associated locking elements can be arranged at least partially on different radii with respect to the common center of rotation.
