Description

The invention relates to a file mechanism with a secured in a closed position against pivoting Umlegebügel according to claim 1.

Folder mechanisms known from the prior art usually comprise a base housing that can be fixed to a folder back or folder lid. The basic housing has at least two spaced apart arranged Aufreihstifte. Further, the file mechanism comprises a by means of a bearing web about a bearing web axis or by means of a mounting rail to a mounting rail axis on the base housing following a pivoting limited between a closed position and an open position pivoting Umlegebügel. The Umlegebügel includes at least two spaced apart the Aufreihstifte held and with these in the closed position to form a closed ring in pairs coupled and in the open position an insertion gap for documents releasing Umlegeschenkel. Furthermore, an actuating lever is present, which is mounted in a housing-fixed bearing about a transverse to the axis of the bearing web or the support rail pivot axis limited pivotally. The actuating lever acts on a crank of the bearing bar or on the mounting rail outside the DIN rail axis, usually against an opening-directed force of a spring element.

Such a folder mechanism is intended primarily for document folders, which consist of a folder back and one hinged to this front and back cover. The folder mechanism is mounted in the vicinity of the folder back on the back cover of the letter folder, that the fold over the operating lever to release the insertion gap between the Aufreihstiften and the Umlebringeln can be pivoted into an open position. In this state, in conventional folders punched records can be inserted or removed on the side of the Aufreihstifte, after previously located thereon documents documents have been transferred while still closed mechanism on the folding bow. In the closed state of the folder, the closed file mechanism with its Aufreihstiften and Umlebringeln from the back cover engages through the folder to the front cover. To ensure that the Aufreihstifte and the associated Umlegebügel bear against each other at their mutually facing front ends in the closed state against each other, the Aufreihstifte frontally conical guide pins which engage in a corresponding inner cone on the associated Umlegebügel. This conical connection has exclusively a centering task. An enlargement of the closing force between Aufreihstift and Umlegeschenkel is not connected. In addition, in the open position of the operating lever access to the folding strap is blocked, so that the documents can not be inserted or removed on the side of the Umlegebügels.

The EP 1 129 865 discloses a folder mechanism which has locking elements with interlocking teeth on the folding leg and on the insertion pins. A disadvantage of this mechanism is that for opening the fold-over first, the locking elements of the folding leg by hand must be solved by squeezing the locking elements of the Aufreihstifte.

A similar mechanism also describes the EP 1 674 288 , which describes a file mechanism according to the preamble of claim 1, wherein in this mechanism, an additional operating lever is present. However, the operating lever only allows the closing of the Umlegebügels. To open the same must Umlegeschenkel be squeezed by hand to release the locking elements.

Further, the EP 1 908 603 a folder mechanism with two relatively movable plates, on each of which a half of the retaining rings are arranged. The two ring halves have an interlocking toothing. By pressing a lever, the two plates can be moved to each other. As soon as the toothing no longer holds the ring halves together, the two plates are tilted against each other by the action of a spring, resulting in an insertion gap for opening.

Similar mechanisms also reveal that EP 1 908 604 . EP 1 908 605 . EP 1 908 606 . EP 2 108 522 . DE 103 93 258 as well as the DE 103 49 614 ,

A disadvantage of these mechanisms, however, is that when opening and closing both plates are tilted, which means that the one half of the ring must be moved together with the leaves inserted in the folder.

Furthermore, the describes DE 36 10 929 a holder for folders. The holding device comprises a fixed carrier plate with Aufreihstiften and a pivotable carrier plate with Umlegeschenkel. The pivotable carrier plate can be displaced against the action of a spring along the pivot axis. The Umlegeschenkel and the Aufreihstifte have locking lugs, which secures the holding device in the closed state against unintentional opening. To open this fixture two separate movements of a user are required. In addition, the holding device or the folder must be held when moving the pivot axis.

Proceeding from this, the present invention seeks to develop a file mechanism of the type specified, which overcomes the disadvantages of the known file mechanisms and in the closed state compared to known file mechanisms increased holding force between Aufreihstiften and Umlegebügel, wherein the pivoting of the Umlegebügels in the simplest possible way should be done. This object is achieved with a file mechanism according to claim 1.

By the locking elements, the holding force between the Umlegelegeln and the Aufreihstiften is increased, so that accidental opening of the filing mechanism, for example by dropping the folder, can be largely avoided.

The control mechanism according to the invention ensures that the sequence of movements, especially during the closing process, can be controlled so that no incorrect operation occurs.

In order to obtain a better motion control during the opening process, the control mechanism is additionally designed so that it releases during the opening process in the manner of a sequential control in a first phase, the path of movement of the Umlegebügels from the closed position to the intermediate position in the opening direction limited pivoting until the locking elements out of engagement have come into their exposed position, and in a second phase, the pivoting of the Umlegebügels to the bearing bar axis or releases the DIN rail axis from the intermediate position to the open position with limited in the closing direction of the locking elements movement path until the insertion gap is open.

This makes it possible in particular that the unlocking and locking of the Umlegeschenkel can be done with the Aufreihstiften and the pivoting of the Umlegebügels with a single operation of the control mechanism.

It has proved to be particularly advantageous if the actuating lever has a closing member acting on the control member against the opening-directed force of the first spring element relative to the pivoting and a directly or indirectly acting on the control member against the force of the second spring element in the locking direction relative to the movement path opening boom ,

In order to allow the insertion of documents on the side of the Umlegeschenkel in the open state, is according to a preferred Embodiment of the invention proposes that the operating lever during the opening process along the pivoting following with its closing arm lifts off the control member and pivots back in the open position under the action of gravity and / or a return spring and lifting the opening arm with his Schliessausleger on the control member. By pivoting back the Einlegespalt on the side of the Umlegeschenkel is made free from the operating lever.

A further preferred embodiment of the invention provides that the control member is limitedly rotated under the action of a parallel guide aligned with the housing and oriented substantially at right angles to the housing support surface about an axis parallel to the bearing web axis or to the mounting rail axis. Basically, it is possible to provide such a construction even with the file mechanism with mounting rail on the folding handle.

A further advantageous structural variant of the invention provides that the first and the second spring element are formed by a single spring, which acts on the one hand directly or indirectly on the control member and on the other hand fixed on the actuating lever or on the housing, wherein the direction of force corresponds to a vector, which results from the virtual directions of force of the first and the second spring element. A particularly advantageous embodiment of this principle is that the first and the second spring element are formed by the two legs and a spring coil of a single leg spring, on the other hand arranged between two on the control member or on the crank of the Umlegebügels one hand and on the actuating lever or on the base housing Bearings are clamped.

Preferably, the two legs of the leg spring are positively inserted into the bearings. The bearings are particularly preferably designed as openings, in particular as bores into which the legs of the leg spring can be introduced. Such an embodiment of the bearing points has the advantage that when assembling the filing mechanism, the control member is pulled by the leg spring in the aligned substantially perpendicular to the housing support surface parallel guide.

A further advantageous structural embodiment of the invention provides that the closing stop and the opening stop are arranged on a housing-fixed stop cam, and that the control member has a control cam acting against the stop cam with complementary to the closing and opening stops control surfaces.

The opening stop is preferably formed such that the control member is simultaneously moved in the closing direction during the pivoting movement from the intermediate position to the open position, so that the Umlegeschenkel in the open position the rowing pins are substantially opposite again. Particularly preferably, the opening stop is at an acute angle to the closing stop. This angle is preferably 60 ° to 80 °, particularly preferably 70 °. By the movement of the control member in the closing direction, the angle between the two legs of the spring increases. The resulting spring force increases the holding force of the filing mechanism in the closed position in addition. In a particularly preferred embodiment, this angle increases from 24 ° in the open position to 30 ° in the closed position. Furthermore, the acute angle between the opening stop and the causes Closing stop that the control member easily "jump" from the closing stop on the opening stop.

Preferably, the opening stop of the stop cam additionally has an angled seat surface, which holds the control member via a complementary configured to the seat control surface on the control cam in the open position. The seat is arranged such that the control member engages upon reaching the open position with the complementary control surface in the seat. As a result, the Umlegeschenkel can move only in overcoming a certain force towards the closed position.

The actuating lever preferably has a retaining element, which limits the pivoting of the actuating lever during the opening process. In this case, damage to the folder mechanism can be prevented by an excessive pivoting of the actuating lever. Particularly preferably, the retaining element is designed as a further arm on the actuating lever, which preferably at the lower end via at least one transversely to the pivot direction projecting element which abuts upon reaching a certain pivotal value of the actuating lever to a mounted in the housing projection or cam.

The locking elements are preferably made of plastic, while the Umlegeschenkel and the Aufreihstifte consist of a metal. The locking elements are particularly preferably connected by means of force and / or positive connection with the folding strap and the Aufreihstiften. This compound is produced in particular by spraying the locking elements on the folding straps and the Aufreihstiften. By injection molding, the locking elements can be both simultaneously produced in one step as well as connected to the Umlegeschenkel and the Aufreihstiften.

The locking elements are preferably designed so that they are overloaded, i. when a certain force is exceeded, deform such that they slip off each other. This prevents damage to the folder mechanism if too much force is applied.

Preferably, the bearing web axis of the folding bail is arranged in the housing in such a way that it is farther away from the file back or folder cover than the metallic web of the alignment pins. This ensures that the offset of the fold over the metallic web of the Aufreihstifte is moved when opened from a position below the metallic web of the Aufreihstifte in a position above this web. Preferably, the bearing web axis of the Umlegebügels is arranged relative to the metallic web of the Aufreihstifte so that when reaching half the maximum pivot angle of the Umlegebügels the offset of the Umlegebügels and the metallic web are both equidistant from the folder back or folder cover. In a preferred embodiment, the angle between the crank of the Umlegebügels and the metallic web in the closed state, for example, -10 ° and in the open state + 10 °. This minimizes the play of the plastic and thus allows a clean guidance of the Stuerglieds.

The actuating lever, the control member and the housing in a particularly preferred embodiment of the present invention made of plastic. In this case, all parts of the filing mechanism are particularly preferably positively and / or non-positively connected. The use of plastic reduces the material costs in the production of the folder mechanism. In addition, plastic offers more possibilities with regard to the design of the folder mechanism.

The folding strap is preferably fastened to the housing by means of at least two fastening elements, preferably arranged in the vicinity of bearing straps, which can be inserted into the housing. The bearing plates serve to guide the Umlegebügels in the housing. The use of insertable fasteners allows a simple and efficient assembly of the filing mechanism.

Furthermore, the actuating lever is preferably composed of an upper and a lower part. The upper part is directed away from the base housing while the lower part is directed against the base housing. This increases the rigidity of the actuating lever, in particular in one embodiment as a hollow construction. Both parts are preferably made of different polymeric materials. Particularly preferably, the upper part of acrylonitrile-butadiene-styrene copolymer (ABS) while the lower part consists of polypropylene (PP). This configuration makes it possible to provide an operating lever with a contact surface of higher quality material (ABS) while the larger volume lower part consists of cheaper material (PP). The two parts are preferably held together positively and / or non-positively. Alternatively, the two parts can be joined by adhesive or by welding together, optionally in conjunction with force or form-fitting connections.

A preferred embodiment of the invention provides that the basic housing of the file mechanism is made of plastic and that the metallic Aufreihstifte are integrally connected to one another via a metallic web fixed to the base housing. With this measure, it is achieved that even with a basic housing made of plastic with low rigidity sufficient dimensional stability is achieved in the field of Aufreihstifte.

It is also conceivable that the basic housing in all variants can be designed as a metallic base plate in the form of a bending stamped part. In that regard, the term "basic housing" is used as a synonym for the term "base plate".

Furthermore, in all embodiments, the first spring element may, for example, be a leaf spring clamped on the base housing, which acts on an offset of the bearing web or on the mounting rail in the opening direction, whereas the second spring element is conceivable as a tension or compression spring which acts in the locking direction of the locking elements. In the illustrated embodiments, both spring elements are combined to form a single spring and designed as a pivot spring.

The folder mechanisms shown in the drawings consist essentially of a base housing 10, two arranged at a defined distance from each other on the base housing 10 Aufreihstiften 12 ', 12 ", along a pivoting between a closed position and an open position limited pivoting Umlegebügel 18, the two at a distance the Aufreihstifte 12 ', 12 "held each other and with these in the closed position ( 4a ) in pairs to form a closed ring 19 and in the open position ( Fig. 4c, 4d Furthermore, an actuating lever 24 which is mounted so as to be limitedly pivotable in a housing-fixed bearing 22 is provided, which has a plurality of functions in the folder mechanisms shown, which are described below.

In the in the FIGS. 1a to 4f In the embodiment shown, the folding legs 18 ', 18 "are arranged on a support rail 14 to form the folding bail 18, which is limited to pivot about a support rail axis 15 on the base housing 10 along a pivoting path between the closed position and the open position Embodiment about a pivotally extending transversely to the support rail axis 15 pivot axis 22 limited in the base housing 10. The operating lever 24 each has an opening arm 26 and a closing arm 28, with which he directly or indirectly via a spring 30 under the opening or closing movement on the Support rail 14 outside the mounting rail axis 15 acts.

A special feature of the invention is the fact that at the free ends of the pairwise complementary Aufreihstifte 12 ', 12 "and Umlegeschenkel 18', 18" complementary to each other, in the closed position ( Fig. 1a . Fig. 3e, Fig. 4e ) of the Umlegebügels 18 interlocked locking elements 32 ', 32 ", 34', 34" are arranged, which give the filing mechanism in the closed state due to a positive connection in this area high closing forces. The locking elements are arranged in such a way that, in order to open the folding bail, an unlocking movement of the folding legs 18 ', 18 "relative to the aligning pins is necessary before the folding bail can be swiveled on its pivoting path its Umlebringeln 18 ', 18 "at the beginning of an opening operation on a movement path relative to the Aufreihstiften 12', 12" under release of an unlocking in an intermediate position ( Fig. 3b . 4d ) with exposed latch elements 32 ', 32 ", 34', 34" ( Fig. 4h ) is movable before the Umlegebügel following his pivoting path ( Fig. 3c, 4c ) can be pivoted. For this purpose, one is the path of movement and the Pivoting the Umlegebügels 18 relative to the base housing 10 controlling control mechanism provided which is so that it releases during the opening process in the manner of a sequential control in a first phase, the path of movement of the Umlegebügels from the closed position to the intermediate position in the opening direction swivel path until the locking elements 32nd ', 32 ", 34', 34" have come out of engagement in their exposed position ( Fig. 4h ) and in a second phase, the pivoting path of the Umlegebügels 18 releases around the DIN rail axis 15 of the intermediate position in the open position in the closing direction of the locking elements limited movement path. The control mechanism is also designed so that it releases during the closing process in the manner of a sequential control in a first phase, the pivoting path of the Umlegebügels to the mounting rail axis 15 in the closing direction of the locking elements limited movement path until the folding bail 18 with its locking elements 34 ', 34 "in the Intermediate position has arrived and in a second phase, the path parallel to the support rail axis 15 of the Umlegebügels 18 releases from the intermediate position to the closed position until the locking elements are locked together.

The control mechanism 36 includes in the in Fig. 1a to 4h shown embodiment, an integrally formed on the support rail 14 control member 38, which during the closing process ( Fig. 3e ) and in the closed position from below with a closing surface 39 abuts against a closing stopper 40 formed by the overlying housing wall and which engages in the open position through an opening 42 in the housing from below and with an opening surface 44 against a bent in the housing upwards Opening stop 46 is present. The control mechanism 36 has in the mentioned embodiment, in addition, a leg spring 30, which with a first spring leg 48 on the housing-fixed bearing 22 and with its second spring leg 50th under bias at a lateral distance to the mounting rail axis 15 abuts against the mounting rail 14.

Starting from the in Fig. 3a, 4a shown closing state of the actuating lever 24 is pivoted about its bearing axis 22 upwards. In this case, the opening lug 26 abuts against the first spring leg 48 and moves the support rail 14 - indirectly via the spring coil 31, which in turn abuts the stop surface 16 for the spring coil parallel to the support rail axis 15 in the in Fig. 3b shown intermediate position, in which the locking elements 34 ', 34 "of the Umlegeschenkel 18', 18" from the locking elements 32 ', 32 "of the Aufreihstifte are solved.In the course of the control member 38 passes with its closing surface 39 in the region of the opening 42, so that it passes upward through the opening 42 when the support rail is raised with the action of the force of the second spring leg 50. The opening stop 46 limits the path of movement of the support rail back into the locking position Fig. 3c released, it pivots under the action of gravity or a pictorial not shown auxiliary spring down until it rests with its Schliessausleger 28 from above on the control member 38 ( Fig. 3d ). In this position, the operating lever releases the insertion gap so far that documents can also be removed from the folding bracket 18 and inserted thereon (cf. Fig. 4d ).

During the subsequent closing operation, the actuating lever 24 is pivoted with its closing arm 28 against the control member 38, so that the support rail 14 against the force of the second spring leg 50 from the position in Fig. 3d in the position according to Fig. 3e arrives. From there, the support rail 14 is under the action of the force of the first spring leg 48 with locking of the locking elements 32 ', 32 ", 34', 34" in the in Fig. 3a moved shown stable closed position.

The embodiment according to Fig. 5a to Fig. 7b agrees both in the structural and in the functional features essentially with the embodiment Fig. 1a to Fig. 4h match. For clarity, the same components are provided with the same reference numerals below. The main difference from the above embodiment is the design of the folding bail 18 and the control mechanism 36 controlling the opening and closing operation of the folding bail 18. The baffles 18 ', 18 "of the bender 18 are integrally connected to each other here via a bearing web 54. The folding bail 18 is connected to the bearing web 54 on bearing plates 56 of the base housing 10 to a bearing housing axis 55 fixed to the housing housing a pivoting path following between the closed position ( Fig. 6b ) and the open position ( Fig. 7b ) limited pivoting. The bearing bar 54 is provided in the middle region with a crank 58, on which a control mechanism 36 is placed from plastic. The function of the control mechanism 36 and its interaction with the operating lever 24 and the leg spring 30 is consistent with the corresponding components of the embodiment Fig. 1 to Fig. 4 match. This applies in particular to the sequence of movements in the opening and closing process, which in the sequence of figures 6a, 6b and 7a, 7b, in accordance with FIGS. 3a . 3d , and 4a . 4d is shown in the drawing.

In the in the FIGS. 8a to 8d shown embodiment of a filing mechanism is similar to the case of Fig. 1 to 4 a folding bracket 18 is provided, the Umlegeschenkel 18 ', 18 "via a support rail 14 at a distance of the Aufreihstifte 12', 12" are held. The only difference to the embodiment after Fig. 1 to 4 is that the folding bail 18 with its support rail 14 is not parallel to the mounting rail longitudinal axis displaceable, but is hinged to a housing-fixed vertical axis 64 pivotally mounted on the base housing 10. The movement path when unlocking the locking elements 32 ', 32 ", 34', 34" is as a turning in the sense of Fig. 8b and 8c designed and not as a displacement. To trigger the opening and closing operation including the unlocking a control member 38 is also provided here, with a housing-fixed opening 42 and a housing-fixed closing stop 40 and a housing-fixed opening stop 46 in the sense of the embodiment according to Fig. 1 to Fig. 4 cooperates and which can be actuated via an actuating lever, not shown, and a leg spring, not shown.

That in the FIGS. 9a to 9g embodiment shown is also close to the embodiment according to Fig. 1 to Fig. 4 ajar. The only difference is that only one of the Umlegeschenkel 18 'and the Aufreihstifte 12' a hook-shaped locking element 34 ', 32', while the other Umlegeschenkel 18 "is designed as a pure pivot lever, the locking element pairing 34"', 32 "' no Movement path parallel to the DIN rail axis 75. The two Umlegeschenkel 18 ', 18 "of the folding bail 18 are here connected to each other via a telescopic support rail 14, one of the telescopic part 74" about the mounting rail axis 15 pivotally, but immovably connected to the base housing 10, while the other telescopic part 74 'relative to the first telescopic part 74 "and the base housing 10 along the support rail axis 75 for the purpose of unlocking the locking elements 32', 34 'on a movement path in an intermediate position is displaceable ( Fig. 9d ), before it is pivotable on the pivoting path together with the first telescopic part 74 "( Fig. 9e ). The operation of the support rail during the opening and closing operation by means of an actuating lever and a leg spring in turn corresponds to that of the embodiment Fig. 1 to Fig. 4 ,

Also in the FIGS. 10a to 10e shown embodiment of a file mechanism corresponds in essential features of the embodiment according to Fig. 1 to Fig. 4 , The only difference is that the mounting rail is formed as a four-bar linkage, which consists of two rotatable about vertical axes of rotation 84 on the base housing 10, each one of the Umlegeschenkel 18 ', 18 "carrying lever elements 86', 86", via a link rod 88 with each other are connected. By this arrangement it is achieved that the Umlegeschenkel 18 ', 18 "in the unlocking in the same direction along a path of movement about the axes of rotation 84', 84" are rotated into the intermediate position ( Fig. 10b ) before being in the spirit of Fig. 10c can be brought into the open position on their pivoting. The operation in the opening and closing operation is also carried out here via an actuating lever 24, not shown, and a leg spring 30 in the sense of FIGS. 1 to 4 ,

In the in the FIGS. 11a to 11f Shown embodiment, the support rail 14 is formed as a link chain (see. Fig. 11 d, 11 e and 11f ), which permits an opposite movement of the folding legs 18 ', 18 "while unlocking the locking elements 34', 34" ( Fig. 11b . 11d ), before the folding bail 18 can be brought into its open position on the pivoting path ( Fig. 11c ). Again, the operation is similar to the case of FIGS. 1 to 4 by means of an actuating lever 24, not shown, and a leg spring 30th

The FIGS. 12 to 15b show a folder mechanism, which in principle as the embodiment according to Fig. 5a to Fig. 7b is formed, in a preferred embodiment for the same practice. The base housing 10 is here designed as a lightweight plastic molding, which has a plurality of stiffening ribs 108 and sufficient for accommodating the various components height. The folding bracket 18 has two over a bearing web 54 integrally interconnected Umlegeschenkel 18 ', 18 "on the bearing points 56 of the base housing 10 about the bearing bar axis 55 on its path of movement in an unlocked intermediate position and slidably pivoted on their pivoting in the opening direction to release an insertion gap The sequence of movements during the opening and closing process corresponds to the movement sequence in all steps Fig. 3a to 3e and Fig. 4a to 4e ,

Another peculiarity of this embodiment is that the Aufreihstifte 12 ', 12 "integrally connected to each other via a bent web 110 and inserted with this in the basic housing 10 against rotation (see. Fig. 12b ). With this measure, a stiffening of the base housing 10 is additionally achieved. The control member 38 of the control mechanism 36 is similar to the case of Fig. 5d slidably mounted on the crank 58 of the bearing web 54 and guided in a hollow chamber 100 of the base housing 10 in the stroke direction. This guide is rigidly aligned vertically, while the control member 38 is mounted at the same time rotatably mounted with its axial aperture 102 on the crank 58 of the bearing web 54. How out Fig. 13e and 13j can be seen, the actuating lever 24 has an opening boom 26 and a closing boom 28. Next there is a leg spring 30 is provided, the first spring leg 48 is mounted at a bearing 104 of the actuating lever 24 and the second - at its free end angled spring leg 50 at a bearing point 106 of the control member 38 and wherein the spring coil 31 of the spring 30 on the opening boom 26th is applied. When lifting the operating lever 24, the folding bail 18 on the opening boom 26 and the leg spring 30 on its path in unlocking the locking elements 34 ', 34 "so far moved until the control member 38 can move together with the crank under the action of the spring 30 in its open position ( Fig. 15a ). In this position, the control member 38 is located with its opening surface 44 against an opening stop 46 ( Fig. 13l ) within the housing, so that only by depressing the operating lever 24 and the control member 38, a closing process can be triggered, which ultimately leads to the locking of the locking elements.

The FIGS. 16 to 18 show details of a further, particularly preferred embodiment of a novel filing mechanism. Like in the FIG. 16a illustrated, the actuating lever 24 is provided with an additional retaining element 29. The retaining element 29 has at its lower end two transversely to the pivoting direction of the actuating lever 24 projecting stop elements 27, which limit the pivoting of the actuating lever 24 by engagement with a corresponding counterpart on the base housing 10. In this embodiment, the retaining element 29 is arranged on the closing arm 28. Alternatively, however, the retaining element 29 may also be arranged in front of or behind the closing boom 28. Further, in this embodiment, the operating lever 24 is slightly curved, which gives the folder mechanism 10 a more elegant aesthetics. The FIG. 16b shows the limitation of the pivoting path of the actuating lever 24. The projecting elements 27 engage under an edge, which the hollow chamber 100 (see FIG. 16b ) of the base housing 10 limited. Like on the FIG. 16a As can be seen, the retaining element 29 is preferably provided centrally with a gap, which facilitates the insertion of the actuating lever into the hollow chamber 100.

The FIG. 17 shows a particularly preferred embodiment of a stop cam, in which on the opening stop 46, a saddle surface 47 is arranged. Figure 17a represents the stop cam in this case in section. As in the embodiment of the stop cam according to Figure 13l , The stop cam is arranged in the hollow chamber 100 of the base housing 10. The opening edge 46 is at an acute angle of about 70 ° to the closing stop 40. On the opening stop 46, a seat surface 47 is additionally arranged. The seat 47 allows engagement of the correspondingly configured opening surface 44 of the control member 38 as shown in FIG FIG. 17b shown. This embodiment of the cam not only allows the movement of the control member 38 in the closing direction of the locking elements 34, but also holds this in the open position.

The FIG. 18 shows the embodiment from below. The web 110 is generally curved in the form of a "U" and inserted into the base body 10, which preferably consists of plastic, by means of snap connection. The folding bracket 18 is designed such that the crank 58 is placed on the control mechanism 36, in the closed position in a plane with the web 110, while this in the field of bearings 56 further up, ie on a folder back or folder cover on away from this. In the area of the bearings 56 of the bracket is held by insertable fasteners 57 in the base housing 10. The FIG. 18b shows such a fastener 57 in detail. A serving as a bearing for the folding strap 18 bridge part 57 '' connects two wall parts 57 'and 57 "together. The fastening element 57 is positively and non-positively connected via wall parts 57 ', 57 "to the base housing 10.

The FIG. 19 shows the sequence of movements when opening a preferred embodiment of the filing mechanism. On the FIG. 19a the folder mechanism is shown in the closed state. The lever 24 rests on the housing 10. The closing surface 39 of the control member 38 is located on the closing stop 40 of the stop cam. The FIG. 19b In the intermediate position, the locking elements 34 ', 34 "of the folding bail 18 are no longer in engagement with the locking elements 32', 32" of the aligning pins 12 ', 12 " This results in a pivotal movement of the actuating lever 24. This also pivots the opening arm 26. This presses as a result of the pivoting movement on the first spring leg 48 and the spring coil 31st As a result, the spring coil 31 and the second spring leg 50 are displaced relative to the housing 10. At the same time, the angle between the first spring leg 48 and the second spring leg 50 changes, whereby a spring force is generated by the spring coil 31, which generates the second spring leg 50 pushes upwards so in the direction of the actuating lever 24. Since the second Fe the thigh 50 is connected via bearing 106 with the control member 38, the control member 38 and the over the crank 58 connected to the control member 38 Umlegebügel 18 is also moved. As a result, the interlocking locking elements 32, 34 separate from each other. By the sliding movement, the closing surface 39 of the control member 38 slides on the closing stop 40 of the stop cam. If the folding bracket 18 has reached the intermediate position, the control member 38 is in the position which is in the FIG. 19b will be shown. The closing surface 39 loses contact with the closing stop 40 and the control member 38 is through the pressed by the pivot spring 30 spring force over the edge 41 of the stop cam pressed. After the control member 38 has been pressed over this edge 41, the opening surface 44 begins to slide on the opening stop 46. The fully open state of the folder mechanism shows the FIG. 19c , Due to the angled arrangement of the opening stop 46 for closing stop 40, the control member 38 moves not only upwards but also back in the direction of the opening arm 26. This results in that the folding bail 18 is not only pivoted along the pivoting path to release an insertion gap, but that in addition, the locking elements 32, 34 in the fully open position perpendicular to each other (see also FIG. 20a ). The relaxation of the spring force causes the opening surface 44 is pulled into the seat surface 47 of the opening stop 46 and engages there. As a result, the folding strap 18 can only be moved out of the open position by applying a certain force. If the actuating lever is released in the sequence, it is pulled slightly downward by the leg spring 30 until the closing arm 28 comes to rest on the closing stop 39.

The FIG. 20 shows the sequence of movements when closing the folder mechanism from the FIG. 19 , In the open state, the locking elements 32, 34 are free, with an insertion gap 20 for documents between them. The folding bracket 18 is accordingly in the pivoted position. The control member 38 is latched via the opening surface 44 with the opening stop 46. To close the folder mechanism now a downward force on the operating lever 24 must be exercised. The actuating lever 24 acts via the closing arm 28 on the closing surface 40 of the control member 38. If now a certain force is exceeded, the control member 38 dissolves from the locking position on the stop cam. By further application of force to the actuating lever 24, the control member 38 is pressed down, wherein the control member is simultaneously moved away from the opening boom 26 by the angled arrangement of the opening stop 46. As a result, the locking elements 34 ', 34 "move relative to the locking elements 32', 32", with the folding strap 18 being simultaneously pivoted back along the pivoting path. The FIG. 20b shows the folder mechanism when reaching the intermediate position. In this case, the folding bail 18 has been pivoted over the entire pivoting path and the control member 38 is located at a transition point at which the control member is located at the edge 41 of the stop cam. By moving the control member 38, the leg spring 30 is pulled out of its rest position and lifts it slightly from the Schliessausleger 26, wherein by the rotation of the two spring legs 48, 50 a direction opening arm 26 directed spring force builds up. As soon as the control member 38 has been pressed over the edge 41 of the stop cam, the control member 38 is pulled by the spring 30 in the direction of the opening arm 26, which results in that the locking elements 34 ', 34 "located on the folding bracket 18 in the on the Aufreihstiften 12 ', 12 "are pulled in and into these snaps. During this sliding movement, the closing surface 39 of the control member 38 slides over the closing stop 40 of the stop cam. The FIG. 20c shows the folder mechanism in the closed position. The angle between the two spring legs 48, 50 increases in the closing movement of about 24 ° in the open state to about 30 ° in the closed state.

The FIG. 21 shows a locking element 32, 34 in detail. The locking element 32, 34 has an undercut 33, in which in the closed state, the corresponding counter-locking element 34, 32 engages. Furthermore, the locking element has 32, 34 via a cam 37 and a groove 35, which preferably have a tapered shape. When closing the folder mechanism engages in each case a cam 37 in a groove 35 of the Gegenverriegelungselements 34, 32. By the tapered shape of the cam 37 bez. the groove 35 can center the interlocking locking elements.
