Abstract

The invention relates to a file mechanism for receiving punched documents. Said file mechanism comprises a housing (10) having spring-elastic bendable housing flanks (28). Two support rails (20, 20') are arranged in the housing (10) and can be pivoted with respect to each other in the manner of a toggle lever in the region of the mutually facing longitudinal edges (24) to form an articulated axis (22). At least two half rings (16, 16'), which are arranged at a defined longitudinal distance from one another and complement each other in pairs to form a ring (14), are rigidly connected to the support rails (20, 20'). Locking elements (32, 32'), which complement each other and are interlocked with each other around the articulated axis (22) in the closed position to prevent pivoting of the support rails (20, 20'), are arranged on the free ends of the half rings (16, 16') of at least one of the half ring pairs. In addition, at least one of the support rails (20') can be moved relative to the other support rail (20) between an overlapping and an exposed position of the locking elements (32, 32') at the start of an opening process in order to trigger an unlocking process. Conversely, the at least one support rail (20') can be moved relative to the other support rail (20) between the exposed and the overlapping position of the locking elements (32, 32') in the course of the locking process. According to a preferred embodiment of the invention, only one of the support rails (20') can be moved parallel to the articulated axis (22), relative to the housing (10), and the other support rail (20) is immobile with respect thereto.

description

The invention relates to a filing mechanism with an elongated, in cross-section C or U-shaped housing having a central housing wall and two lateral, opposite the central housing wall to form longitudinal grooves bent housing flanks, with two arranged in the housing preferably elongated mounting rails, the At their mutually facing longitudinal edges to form a hinge axis against each other and engage with their opposite longitudinal edges in the longitudinal grooves of the housing flanks, each with at least two at their roots in a defined longitudinal distance from each other rigidly connected to the support rails and on the outside of the housing in pairs to a ring complementary half-rings, wherein the support rails are limited to a hinge axis along a pivoting path with entrainment of the half-rings between a closed position and an open position against each other pivotally, and with a the einande r in pairs complementary half-rings in their closed position locking locking mechanism.

In known ring binder mechanisms, the mounting rails are inserted into the housing so that they occupy two locking positions corresponding to the closed position and the open position. The housing acts as a spring element which fixes the half rings in their open position and in their closed position. In the area of the inner longitudinal edges of the mounting rails there are drivers, which ensure that the two mounting rails are always butt against each other at these longitudinal edges. The DIN rails have the function of a spring-mounted on the outer edges Kniehe- bel. The known filing mechanism also has a locking mechanism which comprises at least one locking element, which locks the locked in pairs complementary half-rings in their closed position. The closing effect is effected solely by blocking the mounting rails. This results in the region of the free ends of the half-rings only a limited closing force. In addition, the known locking mechanism has an independently operable from the support rails locking bar on which the locking elements acting against the support rails are arranged (EP 1 189 764 B1).

In order to avoid these disadvantages, it has already been proposed in a file mechanism of the type specified initially (US Pat. No. 7,600,939 B2) that at the free ends of the half rings at least one of the half ring pairs be complementary to one another, forming the locking mechanism, in the closed position against pivoting Support rails are arranged around the hinge axis latched together locking elements, wherein at least one of the support rails at the beginning of an opening operation relative to the other support rail along a movement path under release of an unlocking between an overlapping and an exposed position of the associated locking elements is movable.

Proceeding from this, the present invention seeks to develop a file mechanism of the type specified, which is particularly easy and reliable to handle during the opening and closing process.

To solve this problem, the feature combinations specified in the claims 1, 17 and 23 are proposed. Advantageous embodiments and modifications of the invention will become apparent from the dependent claims.

A first embodiment of the invention provides at least one control unit which is operatively connected to at least one of the mounting rails and which controls the movement path and / or the pivoting travel of the mounting rails relative to one another is provided,

that the support rails are biased at least towards the end of the closing operation and expediently also at the beginning of the opening operation relative to each other in the direction of overlapping position of their locking elements under the action of at least one spring element;

that an actuating member is provided which has an opening arm acting on at least one of the support rails in the opening direction, and which additionally has a pull or push member acting on at least one of the support rails in its direction of movement parallel to the hinge axis;

and that the support rails have in the region of the hinge axis on the respective adjacent support rail cross-driver and attack the opening and closing arm of the actuator only on one of the support rails and the pull or push member of the actuator to the respective other support rail.

The control unit according to the invention ensures that the movement sequence can be better controlled, especially during the closing process. For this purpose, the control unit can be designed so that it releases during the closing process in the manner of a sequential control in a first phase, the relative pivoting of the support rails about the hinge axis parallel with this movement path, until the support rails with their half-rings in the exposed position of the locking elements have come into the closed position, and in a second phase, the relative movement of the support rails parallel to the hinge axis with locked pivoting this releases until the locking elements have reached their locking position.

Deviating from this, the support rails can be relative to each other already in the overlapping position of their locking elements before the end of a closing operation, so that the half-rings lock their locking elements at the end of the closing operation to form a positive and non-positive connection with each other.

To define the above terms, the following should also be stated: In the "overlapping position", the ends of the half-rings carrying the locking elements are aligned with one another; the locking elements are locked in this position in the closed position of the support rails or locked outside their closed position with aligned half-rings. In the "exposed position", the ends of the half-rings carrying the locking elements are offset relative to one another in the longitudinal direction of the mounting rails or are rotated relative to one another. The locking elements in this position release the opening and closing path of the mounting rails with their half rings.

The control unit is expediently additionally designed such that it releases the relative movement path of the movable support rail parallel to the articulation axis during the opening process in the manner of a sequential control, whereby the pivoting travel of the support rails around the Gelenkach- se remains limited until the locking elements of the half rings except Engaged in their exposed position, and in a second phase of the opening operation releases the relative pivoting of the support rails about the hinge axis until reaching the open position and thereby blocks the path of movement of the movable support rail parallel to the hinge axis in the overlapping position of the locking elements. Advantageously, the actuating member additionally has a locking arm acting on at least one of the mounting rails in the closing direction. In this case, it is advantageous if the opening and closing arms of the actuator engage only on one of the support rails and the pull or push member of the actuator only on the respective other support rail.

In all these cases, it is advantageous if the at least one support rail is displaceable relative to the other support rail parallel to the joint axis. In this case, the half rings of the mounting rails preferably engage through housing openings to the outside, wherein the housing openings for the half rings, which are arranged on the support rail displaceable relative to the housing, as the displacement between the exposed and the overlapping position of the associated locking elements delimiting elongated holes are formed ,

According to a preferred embodiment of the invention, the control unit comprises a guide slot preferably arranged fixed to the housing and arranged on one of the support rail in the vicinity of the hinge axis, engaging in the guide slot or against this fitting slide, which may be formed, for example, as bent on the mounting rail tab. Accordingly, the guide slot on a the movement path and / or the pivoting path guiding track for the sliding gate on.

A preferred embodiment of the invention provides that the support rails in the region of the hinge axis on the respective adjacent support rail cross-driver and that the opening and closing arms of the actuator only on one of the support rails and the pull or push member of the actuator only at the other Attacking the mounting rail. Favorable enough, the support rail connected to the tension member is spring-supported against the pulling direction of the tension member.

An advantageous embodiment of the invention provides that the actuating member is designed as a pivotable about an axis transverse to the hinge axis, the central housing wall substantially parallel lever axis pivotable actuating lever. The tension member may comprise a lever arm, which is positively coupled with a rigidly arranged on the support rail in question tab. In particular, the lever arm may have a slot in which engages the bent on the mounting rail by an angle of 80 ° to 100 ° tab with an operating game. Alternatively, the tension member may also be formed as a pull rod, which is mounted on a lever arm of the actuating member and on the respective support rail, preferably with an actuating game. On the side of the actuating member designed as a pull rod tension member may also have a parallel to the lever axis extending turn, which is mounted in a running in the same direction bore of the actuator. In principle, it is possible that a tension spring is integrated in the tension member.

An alternative proposed solution of the invention provides that the actuating member is designed as a pivotable about a transverse to the hinge axis extending, substantially perpendicular to the central housing wall pivot axis actuating lever, arranged with two a lateral distance from the hinge axis, in the direction of support rail bent tabs in depending on a recess of the support rails engages and limited to the two sides under relative displacement of the support rails and the associated half-rings and locking elements is pivotable. The actuation lever may in this case in the overlapping and locked and possibly also in the exposed position of the locking elements on the housing be locked. To close the half rings - pivoted in this case in the exposed position of their locking elements - taking along the support rails on their pivoting by hand between the open position and closed position and between the closed position and open position of the support rails.

In order to reduce the sliding friction between the mounting rails in the displacement direction, it is proposed according to an advantageous embodiment of the invention that at least one hinge element is loosely inserted in the region of the articulation axis between the mounting rails, which surrounds the mounting rail edges in a form-fitting manner. The joint element may be advantageously formed as an elongated kederartiges molding from an elastomeric material. In principle, it is also possible for a plurality of hinge elements, preferably made of metal, to be provided.

Another alternative solution proposed by the invention provides that at the free ends of the half rings at least one of the half-ring pairs mutually complementary, the locking mechanism forming, locked in the closed position against pivoting of the support rails about the hinge axis latch members are arranged, and that one of the support rails at least a relative to the other support rail under triggering a locking or unlocking between an exposed and an overlapping position of the associated locking elements limited movable mounting rail portion, on which each one of the provided with a locking element half-rings is rigidly arranged. The at least one mounting rail section is expedient rotatably limited relative to the other support rail.

A preferred embodiment of the invention provides that one of the mounting rails by a plurality of loosely arranged one behind the other, depending one of the half-rings supporting and limited to the other support rail rotatable carrier rail parts is formed. In principle, it is also possible for one of the mounting rails to be composed of a carrier rail main body carrying at least one of the half rings and at least one carrier rail part rotatable relative to the carrier rail main body and carrying a further half-ring.

Furthermore, in this case, an actuating member may be provided which has an opening arm acting on at least one of the mounting rails in the opening direction, and which additionally has a tension element engaging the at least one mounting rail section, a predetermined play between the tension element on the one hand and the opening boom on the other hand can be trained. Advantageously, the tension element is designed as a pull rod, which is preferably suspended on a lever arm of the lever-type actuating member and on the at least one carrier rail section with an actuating game.

The folder mechanisms shown in the drawing are mainly for

Intake of loose perforated sheets intended, for example, documents or printed matter. Each file mechanism comprises a cross-sectionally C-shaped housing 10, which is a central housing wall 11 and two lateral, opposite the central housing wall 11 with the formation of bearing grooves 26 bent housing flanks 28 includes (Fig. 2h). In addition, in the embodiments shown, three in a defined longitudinal distance from each other, through openings 12,12 'in the housing 10 and cross-fitting in pairs to a ring 14 complementary half-rings 16,16' and an actuator 18,118 provided for opening and closing the rings. The pairwise to the ring 14 complementary half rings 16,16 'are fixed with its root 19,19' rigidly to two support rails 20,20 ', at their mutually facing inner longitudinal edges 24 to form a hinge axis 22 directly or via at least one hinge element 23 ', 23 "bear indirectly against each other and engage with their opposite outer longitudinal edges 25 in the mutually facing bearing grooves 26 which are embossed into the housing flanks 28.

The joint element 23 'shown in Fig. 8a and b is elongated and has a double-T-shaped profile, while shown in Fig. 9a and b designed as a rolling body hinge elements 23 "at a distance between the facing longitudinal edges 24 The hinge elements 23 'are preferably made of an elastomeric material, while the hinge elements 23 "may be made of a metal. The support rails 20,20 'are inserted into the housing 10 so that they can assume two stable end positions, namely a closed position in which the half-rings form a closed ring 14 (FIG. 4a) and an open position in which the half-rings 16, 16 'are open at their free ends (Figure 6a). The housing can act as a spring element which fixes the half rings 16, 16 'in their open position and in their closed position. In the region of the inner longitudinal edges 24 of the support rails 20,20 'there are drivers 30 or the joint elements 23', 23 ", which are responsible for this. conditions that the two support rails 20,20 'there always abut against each other. The support rails 20,20 'have the function of a hinged to the outer longitudinal edges 25 toggle lever. Thus, the support rails 20,20 'can be pivoted about their hinge axis 22 with entrainment of the half rings 16,16' limited between the open position and the closed position against each other.

In addition, a locking mechanism is provided which locks the pairwise complementary half rings 16,16 'in its closed position. A special feature of the invention is that the locking mechanism at the free ends of the half rings 16,16 'at least one of the half-ring pairs complementary, locked in the closed position against pivoting of the support rails 20,20' about the hinge axis 22 with each other hook-like locking elements 32,32 'formed in the material of the half-rings. In order to perform an opening operation by pivoting the support rails 20,20 ', additional precautions are taken to ensure that at the beginning of an opening operation unlocking the locking elements 32,32' is triggered, so that the pivoting of the support rails about its hinge axis 22nd is released. For unlocking there are several possibilities according to the invention, which will be explained in more detail below with reference to the various embodiments.

In the embodiment shown in FIGS. 1 to 8, one of the support rails 20 'is displaceable parallel to the articulation axis 22 relative to the housing 10, while the other support rail 20 is non-displaceable relative thereto. The displacement of the first support rail 20 'is made possible in that the openings 12' in the housing 10, through which the associated half-rings 16 'pass outwardly, are formed as slots (see Fig. 1 a). With this provision, it is possible that the one support rail 20 'at the beginning of an opening operation relative to the other support rail 20 by triggering an unlocking between an overlapping position (Fig. 4c) and an exposed position (Fig. 5c) of its locking elements 32,32' is displaceable in order to pivot in a subsequent actuation step, the half rings 16,16 'in its open position (Fig. 6c) can. Conversely, in the course of a closing operation, the support rail 20 'is moved relative to the other support rail 20 between the exposed and the overlapping position of its locking elements 32,32'. This can be done either by displacing the mounting rail 20 'relative to the other mounting rail 20 between the exposed and overlapping position of the locking elements 32, 32' at the end of the closing operation. In principle, it is also possible for the mounting rail 20 'to be in the overlapping position of the locking elements 32, 32' even before reaching the closed position, and for the half rings 16, 16 'to reach the closed position of the mounting rails with their locking elements 32, 32' with the formation of a positive and non-positive connection taking advantage of the inherent elasticity of the half rings 16,16 'engage each other.

In order to be able to coordinate the movement path of the displaceable support rail 20 'parallel to the articulation axis 22 and the mutual pivotal movement of the support rails 20, 20' about the articulation axis 22 in the above sense during the opening and closing operation, in the exemplary embodiment shown in FIGS a control unit 34 is provided which is fixed to the housing and which has a guide slot with a guide track 36 and 38 for a near the hinge axis 22 on the sliding support rail 20 'arranged, designed as a flap sliding member 40.

The control unit 34 is designed so that during the opening process in a first phase, the movement path of the support rail 20 'with his Glide bar 40 along the guide path 38 parallel to the hinge axis 22 releases and blocks the pivoting or at least restricts until the locking elements 32,32 'of the half rings 16,16' disengaged, and in a second phase releases the pivoting path to the open position and the Movement path in the direction of overlapping position of the locking elements by the transversely to the hinge axis 22 extending guide path 36 for the sliding member 40 blocks. Conversely, the control member 34 ensures that during the closing process in a first phase of the movement path of the support rail 20 'is blocked by the guide member 40 via the guide member 36 until the support rails have arrived with their half-rings 16,16' in the closed position, and in one second phase of the movement in the direction of overlapping position of the locking elements 32,32 'along the guide path 38 is released until the locking elements 32,32' have come into their overlapping and locked position. In order for the locking to take place automatically during the closing operation, the displaceable support rail 20 'is pretensioned at least during the opening or closing operation in the direction of overlapping position by a tension spring 42 clamped between the control unit 34 and the support rail 20' at the suspension points 42 ', 42 " (see Fig. 2b, c and Fig. 4f, 5f, 6f).

The bias of the tension spring 42 is carried out primarily during the opening process via the actuator 18. The actuator 18 has for this purpose on the displaceable mounting rail 20 'attacking coupling point 44. In the embodiment shown in Fig. 4g and 7a, the coupling point 44 is formed on the actuator 18 as a slot in which the displaceable support rail 20 'engages with its bent end 46 with a certain play. In the modified embodiment shown in Fig. 7b, the coupling point 44 additionally comprises an existing of a bent wire tension member 48 which extends between a lever arm 50 of the actuator 18 and a slot opening 52 in the slidable mounting rail 20 'extends. This side of the actuator 18 is exclusively for the displacement of the support rail 20 'determined.

On the other side of the actuating member 18 are an opening cantilever 54 and a closing cantilever 56, which include a gap 59 for receiving the free end 58 of the non-displaceable support rail 20 (FIGS. 4e, 5e, 6e). The triggering of the pivotal movement of the support rails 20,20 'thus takes place exclusively via the non-displaceable support rail 20, which is coupled in the joint area via the drivers 30 or the joint elements 23', 23 "to the displaceable support rail 20 ' 4f, 5f and 6f is described during the opening process, whereby the actuating member 18 is designed to be parallel to the central housing wall 11 and extending transversely to the articulation axis 22 Rotary axis 60 pivotable actuating lever formed.

As a result, the actuating member 18 thus in the opening and closing two effective in different angular positions actuating positions for a subsequent operation of the support rails 20,20 ', wherein the support rail 20' for the purpose of unlocking and locking the locking members 32 in the direction of Joint axis 22 is moved and the support rail 20 for the purpose of performing an opening and closing movement of the half rings 16,16 'about the hinge axis 22 with the support rail 20' is pivoted.

The exemplary embodiment according to FIGS. 10a to 14b differs from the exemplary embodiment described above in that only the middle half-ring pair 16, 16 'is provided with mutually complementary locking elements 32, 32' at their free ends and that the one half-ring 16 'of this half-ring pair its root 19 'at one of the sliding support rail 20 rotatable mounting rail section 62 of the support rail 20 'is fixed. As can be seen from FIGS. 11b, 12b, 13a and 14a, the two outer half-ring pairs 16 ", 16 '" arranged on the carrier rail body 64 each have a wedge locking acting only in the longitudinal direction 66, which dissolves when pivoting the support rails 20,20 'without a cross-locking and closes. In the middle region, the carrier rail main body 64 has a narrow web 65 on which the carrier rail section 62 can slide. The support rail part 62 is supported with a sliding shoe 63 on the inner longitudinal edge 24 of the support rail 20 so that both a longitudinal guide along the longitudinal edge 24 and a pivoting movement about the hinge axis 22 is ensured. In addition, the carriers 30 on the carrier rail main body 64 ensure that the carrier rails 20, 20 'always abut against each other at their longitudinal edges 24. The DIN rail 62 has at its outer edge two more support tabs 67 ', 67 ", with which it engages in the mounted state in corresponding bearing recesses 69', 69" of the housing 10 and is secured there against displacement. Furthermore, a spring element 76 is integrally formed on the carrier rail section 62, with which the carrier rail section 62 is supported inside the housing flank 28 in such a way that a resilient initial tension takes place in the direction of the overlapping position of the latch element 32 '(compare FIGS 12a, b).

The half-ring 16 'is by rotating the mounting rail portion 62 to trigger a locking or unlocking of the associated locking elements 32,32' of an overlapping, parallel to the other half-ring 16 aligned position (Fig. 11 b) in one opposite the other half-ring sixteenth angled exposed position (Fig. 12b) limited pivoting. In the exposed position, the locking elements 32,32 'out of engagement, so that the half rings 16,16' by pivoting the two support rails 20,20 'order the hinge axis 22 can be pivoted into its open position shown in Fig. 13a.

The actuation of the pivotable mounting rail portion 62 via a pull rod 68 which extends between a lever arm 70 of the lifting-type actuating member 18 and a slot opening 72 in the mounting rail portion 62. The locking and unlocking of the locking elements 32,32 'on the pivotable mounting rail part 62 on the one hand and the opening and closing movement of the half rings 16,16' by mutual pivoting of the support rails 20,20 'takes place here in the manner of a sequence control on the actuator 18th The various positions of the actuating member 18 in the course of the sequence control result, for example, from the sequence of figures 11, 12, 13 and 14. The movement sequence between FIGS. 11 a, b and 12 a, b shows the unlocking operation and between FIGS. 12 a, b and 13 a , b the actual opening process. Another special feature of this locking device is that the actuating member 18 can be swung back from the open position back to its original position, without causing a closing movement of the half rings 16,16 '(Fig. 14a, b). In the latter process, the carrier rail section 62 with the associated half-ring 16 'is pivoted back into its starting position, so that an aligned alignment of the half-rings 16, 16' and thus easy handling when loading the mechanism with documents is achieved. The outer half-ring pairs 16 ", 16 '" arranged on the carrier rail body 64 experience no rotation during the opening and closing process. They are at their wedge lock 66 when pivoting the support rails 20,20 'solved without cross-locking and closed.

The actual closing of the half rings 16,16 ', 16 ", 16'" does not take place via the actuating member 18, but by compressing one of the half-ring pairs in the closing direction. It comes in the closed position to mutual locking of the locking elements 32,32 'in the detent position shown in Fig. 11. Accordingly, the actuating member 18 in this embodiment has only one voltage applied against the support rail 20 opening boom 54. The locking boom is here in view of the manual operation during the closing process unnecessary.

The embodiment shown in FIGS. 15a to 16b is a modification of the embodiment according to FIGS. 10 to 14. The essential difference is that in this case all three half-ring pairs have locking elements 32, 32 'at the ends of their half-rings 16, 16' in the closed position of the half rings 16, 16 'lock each individual half-ring pair against an opening operation. The elongated support rail 20 is also arranged immovably in the housing 10 here. The support rail 20 ', however, is composed of three opposite the support rail 20 pivotable support rail sections 62, to which in each case one of the half rings 16' of each half-ring pair is fixed with its root 19 '. The carrier rail main body according to FIGS. 10 to 14 can be dispensed with in this case. The carrier rail parts 62 are each supported by a sliding shoe 63 on the longitudinal edge 24 of the adjacent support rail 20 and engage with their support lugs 67 ', 67 "in bearing recesses, not shown, of the adjacent housing flank Housing inner surface or at the longitudinal side edge 24 of the adjacent support rail 20 are supported so that they are biased in the direction of overlapping position of the Verriegelungsele- elements 32,32 'The support rail parts 62 via a common linkage 74 by means of the actuator 18 between an overlapping position (Fig 16a) and an exposed position (Fig. 16b) of the locking elements 32 'The actuating element 18 has a double function in this case: Firstly, by pivoting the carrier rail section 62, an unlocking operation takes place between the overlapping position (FIG. 16a) and the exposed position (FIG. Fig 16b). Upon further depression of the actuating member 18, an opening arm 54 arranged on the actuating member ensures that the mounting rails 20, 20 'are pivoted relative to one another about their joint axis 22 while the half rings 16, 16' are spread apart. The opening procedure is similar to the previous embodiment of FIGS. 12b and 13a. Since a locking arm is also missing here, can be effected by pivoting back the actuator 18 in the starting position an aligned alignment of the angled half-rings 16 'relative to the half-rings 16, which allow easier insertion of documents. During the closing process, one of the half-ring pairs is pressed against one another by hand until the half-rings 16, 16 'latch into one another on their locking elements 32, 32' (FIG. 16 a).

As a result, here the actuating member 18 only in the opening direction two effective in different angular positions actuating positions for a subsequent operation of the pivotable mounting rail parts 62 on the one hand and the opening movement of the support rails 20,20 'on the other. In the closing direction only the mounting rail parts 62 and the associated half rings 16,16 'are pivoted back to their original position, while the actual closing movement is performed by squeezing one of the half-ring pairs by hand.

A third embodiment is shown in FIGS. 17a to 20b. The with their roots 19,19 'directly to the support rails 20,20' fixed HaIb- ring pairs 16,16 'are there at their free ends with complementary to each other, in the closed position against pivoting of the support rails 20,20' about the hinge axis 22nd locked together locking elements 32,32 'provided. In order to unlock the locking elements 32,32 ', both support rails 20,20' in opposite directions to each other and relative to the housing 10 by means of an actuating member 118 slidably. The actuating member 118 is there as extending transversely to the hinge axis 22, formed to the central housing wall 11 substantially vertical pivot axis 80 pivotable actuating lever. The actuator 118 engages with two lateral spaced from the hinge axis 22, in the direction of support rails 20,20 'bent tabs 82,82' in each open-edged recess 84,84 'of the support rails 20,20' and is on the two sides under relative displacement of the support rails 20,20 'limited pivoting. The actuating member 118 is here exclusively intended to lock or unlock the half rings 16, 16 'in the sense of FIGS. 17a and 17b. For this purpose, the support rails 20,20 'on the bent tabs 82,82' in the sense of Fig. 18a and b and 19a and b against each other. The actual opening and closing operation of the half-rings 16, 16 'takes place by hand via the half-rings themselves (FIGS. 17c and d and 18c and d). Since between the support rails 20,20 'the hinge axis 22 bridging driver 30 are arranged, only one of the half rings 16,16' must be pivoted relative to the housing 10 during opening and closing operation. The other half rings are taken over the associated support rails 20,20 '(see Fig. 20b). In the pivot axis 80 of the actuator 118 is a relative to the housing 10 rotatable hinge pin 86, from which the tabs 82.82 'protrude radially. The pivoting movement is limited by a slot 88 relative to a housing-fixed pin 90. In the overlapping position of the locking elements 32, 32 ', the actuating member 118 can be locked on the housing 10 (FIG. 17 a). For this purpose, a latching tongue 92 formed on the housing 10 is provided, which engages in the locking position in a latching recess 94 of the actuating member 118.

In summary, the following should be noted: The invention relates to a file mechanism for receiving punched records. The filing mechanism has a housing 10 with elastically bendable housing flanks 28. In the housing 10, two support rails 20,20 'are arranged, which in the manner of a toggle lever in the region of their facing each other Longitudinal edges 24 to form a hinge axis 22 are mutually pivotable. With the support rails 20,20 'are at least two in a defined longitudinal distance from each other, in pairs to a ring 14 complementary half-rings 16,16' rigidly connected. At the free ends of the half rings 16,16 'at least one of the half-ring pairs are mutually complementary, in the closed position against pivoting of the support rails 20,20' about the hinge axis 22 locked together locking elements 32,32 'arranged. In addition, at least one of the support rails 20, 20 'is movable relative to the other support rail 20, 20' at the beginning of an opening operation, thereby triggering an unlocking between an overlapping and an exposed position of the locking elements 32, 32 '. Conversely, in the course of the closing operation, the at least one support rail 20 'relative to the other support rail 20 between the exposed and the overlapping position of the locking elements 32,32' movable. A preferred embodiment of the invention provides that only one of the support rails 20 'parallel to the hinge axis 22 relative to the housing 10 slidably and the other support rail 20 is opposite thereto immovable.
