Definitions

  • the invention relates to a letter folder with a folder cover, preferably made of stiff cardboard material, and a folder mechanism that can be releasably fastened with its base plate to the inside of the folder 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 factory-riveted to the back cover of the folder cover. This means that the folders can be used immediately without any assembly effort.
  • the empty folders require considerable storage and transport space.
  • the latching takes place there via resilient tongues or resilient impressions standing up on the insert plate. With these measures it is possible to change the folder mechanics and bindings to be stored and sent separately.
  • the additional insert plate made of metal is very expensive and has upstanding metallic latching parts which, in the case of a tight packing for shipping purposes, can damage the adjacent 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 elements for fastening the folder mechanics can be integrated into openings in the relatively thick cardboard material of the folder cover in such a way that they only protrude little over the broad side surfaces of the folder cover.
  • the binder bindings can be stacked one on top of the other for storage and packaging purposes.
  • at least two holding elements anchored at a distance from one another in an opening of the folder cover are provided, which have a latching cam projecting towards the inside of the folder cover for a locking cam located in the base plate. before wearing recess.
  • four holding elements anchored in each opening of the binder cover are provided, two of which are each arranged in pairs on straight lines parallel to one another or circles concentric with one another.
  • the latching cam is designed as a plastic molded part which is positively plugged onto the holding element from the inside of the binder cover and can be positively latched in the latching recess of the base plate.
  • the plastic molded part is expediently plugged with a central recess that is widened at the end onto the inside end of the holding element that has a corresponding thickening, while on the outside it has an annular groove that surrounds the holding element at a distance from its inside end for the positive reception of the catch recess edge of the base plate has in the locking position.
  • the locking recesses in the base plate expediently have the shape of a keyhole-like elongated hole with a wide insertion area and a narrower locking area for the associated locking cams.
  • the holding element expediently has the shape of a hollow rivet with a snap-on cam attached, the snap-in cam being able to engage in an internal stamping or material compression of the binder cover.
  • the folder mechanism is securely held in place on the folder cover if, according to a preferred embodiment of the invention, it consists of an edge section At least one barb-like latching tongue is punched out of the base plate material in the recess between the insertion and latching area and is preferably resiliently bent out of the base plate level.
  • Two latching tongues arranged on opposite longitudinal sides of the latching recess are expediently provided.
  • the latching tongues advantageously have an ascending slope for the latching cam from the insertion area to the latching area.
  • Figure 1 is a side view of a folder mechanism releasably inserted in a folder cover
  • FIG. 2 shows a plan view of the folder mechanism according to FIG. 1;
  • FIG. 3 shows an enlarged detail from FIG. 1.
  • the letter folder shown in the drawing consists essentially of a folder cover 10 made of stiff cardboard material, optionally provided with a cover, and a folder mechanism 16 detachably fastened to the inside of the folder cover 10 with its base plate 18.
  • the folder mechanism reaches with vertically protruding alignment pins 20 and a two-legged folding bracket 22 bent from metal wire through the interior of the folder in the direction of the lid through.
  • the folder mechanism is actuated via an actuating lever 24 which is pivotably mounted on a bearing plate 26 fixed to the base plate and acts from above against a crank 30 of the folding bracket 22 which is under the action of a leaf spring 28.
  • holding elements 34 designed as hollow rivets are inserted into the openings 32 with their thickened head part 36 projecting from the outside after the inside of the cover and there are arranged with a latching cam 38 which is plugged onto the head part 36 and is designed as a molded plastic part kert.
  • the locking cam 38 has a central, open edge recess 40 which has a corresponding extension 41 for receiving the thickened head part 36.
  • the latching cam 38 is provided with an annular groove 42 which comprises the holding element 34 outside the head part 36 and with a foot part 46 which engages in an annular indentation 44 of the cover.
  • the holding element 34 is supported with its flange 48 on the outer surface of the binder cover 10.
  • a total of four holding elements 36 with locking cams 34 are arranged in pairs on parallel straight lines on the binder cover 10.
  • the base plate 18 of the file mechanism 16 is provided with four keyhole-like, recessed recesses 50 which are oriented in the same direction and which have an insertion region 52 of larger diameter and a narrow Ren have locking area 54 for the locking cams 38.
  • a narrow Ren have locking area 54 for the locking cams 38.
  • Arranged on the transition section between the insertion area 52 and the latching area 54 are two opposing barb-like latching tongues 56 for the latching cams 38 which are bent out of the base plate toward the inside.
  • the folder mechanism 16 is first inserted with the insertion areas 52 of its latching recesses 50 onto the four latching cams 38 of the folder cover 10 and then shifted in the direction of the latching area 54 with respect to the latching cams 38.
  • the latching cams first run on the run-up bevels of the latching tongues 56 until the latching tongues are spread out behind the latching cams 36 in the latched position, forming a positive connection.
  • the latching tongues 56 must first be pressed down into the base plate plane so that the base plate can be displaced relative to the latching cams 36 in the direction of insertion regions 52 and can be removed from the latching cams 32.
  • the invention relates to a letter folder with a folder cover 10 made of stiff cardboard material and a folder mechanism 16 which can be releasably attached to the base plate 18 on the inside of the folder cover 10.
  • the folder mechanism with as little additional dimension as possible

Abstract

L'invention concerne un classeur pour lettres qui comprend une couverture (10) en carton rigide et un mécanisme de classeur (16) pouvant être fixé amovible sur la partie intérieure de la couverture (10). Afin de pouvoir fixer de manière amovible le mécanisme de classeur sur la couverture (10) en utilisant le moins possible de matériau supplémentaire, il est prévu de placer au moins deux éléments de retenue (34) ancrés à distance l'un de l'autre dans un passage (32) pratiqué dans la couverture (10). Ces éléments de retenue (34) comportent une came d'arrêt (38) se présentant sous forme de pièce moulée en plastique et faisant saillie vers le côté intérieur de la couverture (10) du classeur, qui est destinée à venir se loger dans une cavité d'encliquetage (50) se trouvant dans la plaque de base (18).
