Description

The invention relates to a rotary latch lock for flaps or hoods or the like of motor vehicles, in particular of agricultural machinery, with a rotary latch assembly.

A rotary latch arrangement for a vehicle door lock is for example from the DE 196 53 169 A1 known. This rotary latch assembly has a flat cuboid lock case, which is arranged on a vehicle door, not shown, of a vehicle, and includes the components necessary for locking closing. Towards a locking pin projecting horizontally on the doorpost, a box bottom wall and a box longitudinal wall have a recess in which the locking pin is received in the closed state of the door. Adjacent to the recess above and below this and aligned one above the other, and arranged at a small distance from each other, the lock case has one, to a rotary pivot pin pivotable plate-shaped rotary latch. The rotary traps have outwardly, in the direction of the locking pin on the lock case projecting locking lugs. The locking lugs each have a groove in a circumferential wall of the rotary latch. The grooves of the locking lugs point towards each other. In addition, two rotary coil springs are provided, which are arranged around the rotary pivot pins around. These rotary coil springs have the tendency to keep the rotary latch in an open position, so to press apart the locking lugs facing each other. Furthermore, two adjacent, substantially V-shaped recesses are introduced into the peripheral walls of the rotary traps, with the locking recesses of both rotary traps are opposite in the open lock position.

In which the recess for the locking bolt opposite portion of the lock case, a locking lever or a pawl is disposed between the rotary latch and the box longitudinal wall. The locking lever is pivotable about a locking lever pivot pin which is arranged horizontally in a corner region of the lock case adjacent to the box longitudinal wall and a box transverse wall. At one end of the latching lever is formed on the rotary trays assigning locking piece having two end edges and rotary latch side, a longitudinal edge connecting the end edges, wherein in the longitudinal edge a Längskantenauskehlung is introduced, so that each one lever catch nose is formed. With the lever locking lugs the locking piece is in the open position initially on the peripheral wall of the rotary traps under pressure a, z. B. spiral, locking lever spring.

If a vehicle door is closed, the horizontal arranged on the door post locking bolts in the region of the grooves of the rotary traps, By the pressure of the locking pin on the rotary traps they are pivoted against the pressure of the rotary latch springs about the rotary pivot pins in opposite directions of rotation. Due to the rotational movement, the locking lugs reach behind the locking bolt and surround it. In the closed position, the locking pin between the two rotary traps in the region of the grooves. By pivoting the rotary traps initially reach the first V-shaped locking recesses in the region of the locking piece, wherein snap in the first recesses due to the pressure of the detent lever spring lever cam lugs. In this so-called safety catch the lock is not completely closed, but can not be opened due to the blocking effect of the locking lever. Upon further pivoting of the rotary traps, the locking piece with the lever locking lugs in each case a second recess of the rotary traps and snaps there. The rotary traps are now based on the flanks of the recesses on each flank of the lever lugs of the locking piece and are held against the pressure of the rotary latch springs in the closed position.

If the rotary latch assembly to open the vehicle door to be opened, an actuating mechanism which is located in the door is actuated. This actuating mechanism has a U-shaped lever which acts, for example, on the lever pin of the detent lever or is made in one piece with the detent lever and pushes it out against the pressure of the detent lever spring and the rotary latch springs from the detent recesses. If the lever lugs have left the corresponding recesses, the rotary latches snap under the pressure of the rotary latch springs in their starting position, ie the open lock position, back. The locking pin is moved out of the lock case by the flanks of the grooves.

A manual and by means of a remote control and lockable actuating mechanism for such a rotary latch assembly is for example from the DE 10 2004 009 366.0 known. This actuating mechanism has a handle body, which is substantially U-shaped, with a base leg, a first U-leg and a second U-leg, wherein in the second U-leg an actuating device for driving an actuating element for a lock mechanism, eg for a rotary latch assembly, and in the base leg a locking device having a remote-controlled drive device is mounted. In this case, the actuating device has a substantially cylindrical push button with a substantially cylindrical push button shell and a substantially cylindrical push-button lower part and a lock cylinder, wherein in the push-button top of the lock cylinder sits by means of a clip connection. In addition, the push-button upper part, the push-button lower part and the actuating element in the direction of an actuating axis coaxially with each other and arranged one behind the other, wherein the actuating element in the direction of the actuation axis immovably with the push-button base is in communication and the push-button lower part in the direction of the actuating axis in locked position of the actuating mechanism slidably and mechanically coupled and in unlocked position of the actuating mechanism immovable and mechanically decoupled with the push-button top is in communication. As a result, in the unlocked position of the actuating mechanism by manually pressing the push-button top in the direction of the actuating axis and the push-button lower part and the actuator by a predetermined length I and moved by the extension of the actuator by the length I then a lock mechanism is actuated by the actuator on, for example from the DE 196 53 169 A1 known lever pin of the locking lever acts. In the unlocked position of the actuating mechanism, the push-button upper part is displaceable relative to the push-button lower part in the actuating direction, so that only the push-button upper part is displaced axially by pressing the push-button upper part. An actuation of the lock mechanism by the actuator is thus omitted.

For locking and unlocking, the actuating mechanism has a manually operable coupling member in the form of a slide, which is displaced by inserting a key in the lock cylinder and then turning the key and thereby the push-button shell and the push-button bottom mechanically coupled or decoupled. Furthermore, the actuating mechanism on a second movable coupling member in the form of a slider which is displaceable by means of the remote-controlled drive means and thereby the push-button top and the push-button lower part are mechanically coupled or decoupled.

This manually and by means of a remote control and lockable operating mechanism has been proven for the operation of door locks of vehicles. For the use of flaps or hoods of vehicles, which usually do not have to be openable and lockable, this actuating mechanism, however, is too expensive and therefore too expensive due to the necessarily numerous individual components. The object of the invention is to provide a rotary latch lock for hoods and flaps or the like for vehicles, which is simple in construction, can be produced inexpensively and offers a certain security against opening by unauthorized persons.

This object is achieved with the features of claim 1. Advantageous developments of the invention are characterized in the subclaims.

The mechanism of the lock, which is used in vehicles from the agricultural sector, can only be opened with a "tool". This can be a coin, an open-end wrench, or another item, but not a beard key. This makes a random opening or opening impossible by hand.

In the following the invention will be explained in more detail by way of example with reference to a drawing.

The rotary latch lock 1 according to the invention comprises a cuboid lock case 2 with a flat bottom plate or rear wall 3, a plate-shaped cover or a front wall 4 opposite the base plate 3 and two longitudinal walls 5 parallel to one another and perpendicular to the bottom plate 3 , 6 and two mutually parallel and perpendicular to the longitudinal walls 5,6 transverse walls 7,8 (Fig.1-17).

In the lock case 2 is seen from the longitudinal wall 6 from a continuously through the bottom plate 3, the lid 4 and the longitudinal wall 6 extending groove-shaped locking pin recess 9 is provided, the space for receiving a locking bolt 10 (Figure 6) creates, whereupon further down will be discussed in more detail. The locking pin recess 9 is preferably formed symmetrically to a longitudinal wall 6 to the vertical and parallel to the Querwandungen 7.8 Aussparungsmitenebene 11 and extends from the longitudinal wall 6 in the bottom plate 3 and the lid 4 into and ends in a suitably round, preferably circular, recess bottom 12. In particular, the locking pin recess 9 in a view perpendicular to the bottom plate 3 has a course that is similar to the outline of a bell.

According to a first embodiment of the rotary latch lock 1 according to the invention a rotary latch 13 is disposed within the lock box 2, which is rotatably mounted with a cylindrical Drehfallenlagerungsaussparung on a, preferably hollow cylindrical, Drohfallenlagerungsbolzen 15 about a Drehfallenlagerungsbolzenachse 16, wherein the Drehfallenlagerungsbolzenachse 16 is perpendicular to the bottom plate 3 ( Fig. 7). The rotary latch support pin 15 is suitably fixedly connected to the bottom plate 3, in particular, the rotary latch bearing pin 15 has an internal thread (not shown) and is screwed to the bottom plate 3 by means of a not shown slotted screw by a conical screw recess 17 (Fig.7) in the bottom plate 3 is performed and is supported on this with her screw head. In addition, the rotary latch bearing pin 15 is arranged in a spanned by the longitudinal wall 5 and the transverse wall 7 corner region.

The mounted on the rotary latch bearing pin 15 rotary latch 13 is plate-shaped and formed for example of steel and extends parallel to the bottom plate 3 and slightly spaced from this. The rotary latch 13 has in its Drehfallenumfangswandung 21 a groove-shaped recess 19 with two preferably mutually parallel Auskehlungsseitenwandungen 23, 24, which open into a semi-circular groove bottom 18, wherein the groove 19 for receiving the perpendicular to the bottom plate 3 extending and cylindrically shaped locking bolt 10 is used, which will be discussed later , Conveniently, the radius of the Auskehlungsbodens 18 corresponds to the radius of the locking bolt 10th

Furthermore, the rotary latch circumferential wall 21 has a locking lug 20 with two locking lug walls 22a, 22b tapering towards each other on the side of the longitudinal wall 6 having the locking bolt recess 9 in the circumferential direction adjacent to the recess 19, the latching lug wall 22b the longitudinal wall 6 facing Auskehlungsseitenwandung 23 corresponds.

Furthermore, the Drehfallenumfangswandung 21 a rotary latch detent projection 62 with a central and preferably V-shaped or U-shaped rotary latch detent recess 25, which is also arranged in the circumferential direction adjacent to the locking lug 20 on the other side. In this case, the rotary latch detent recess 25 has two rotary latch detent recess 25 delimiting flanks 26,27. Of the two flanks 26, 27, the flute 19 facing the front flank 26 is long and flat, and the flank 27 is short and steep in comparison to the other, so that the rotary latch detent recess 25 is formed undercut. By the rotary latch detent recess 25, the rotary latch detent projection 62 is divided into front and rear rotary detent latches 63, 64 which are circumferentially adjacent to each other. The two lug catch latches 63; 64 each have front and rear latches catch noses flank 63a, b; 64a, b, the rear lash catch lug flank 63b of the forward lug catch 63 of the forward flank 26 of the catch latch recess 25 and the forward rotation latch lobe flank 64a of the rear lug catch lug 64 of the rear Flank 27 of the rotary latch detent recess 25 corresponds (Fig.2,4).

In the catch 13, a continuous, parallel to the Drehfallenlagerungsbolzenachse 16 extending bore 28 is also introduced, which serves to support a rotary latch spring, in particular a rotary shaft rotator 29 (Figure 7), which is arranged around the rotary latch bearing pin 15 around and with a spring leg the bore 28 is supported (not shown). The rotary latch spring 29 has the tendency to rotate the catch 13 in its open position (Figure 4), that is, the locking lug 20 against a Drehfallenschließdrehrichtung S on the locking pin recess 9 having longitudinal wall 6 to move. As an abutment for this rotational movement serves a transverse inner wall 7a, to which the rotary latch 13 abuts the inside with a rounded stop edge 30 which is provided in the Drehfallenumfangswandung 21 adjacent to the locking lug 20.

For actuating the rotary latch 13, the rotary latch lock 1 also has a latching or actuating or blocking lever 31, which holds the rotary latch 13 in safety catch or in a locked position (FIG. 1, 2) or releases the rotary latch 13 (FIG .4). The locking lever 31 is also preferably plate-shaped, e.g. made of steel, formed and extends parallel to the bottom plate 3. Furthermore, the locking lever 31 is analogous to the rotary latch 13 with a cylindrical locking lever bearing recess (not shown) rotatably mounted on a, preferably hollow cylindrical, locking lever support pin 32 about a Sperrhebeitagerungsbolzenachse 33 (Figure 8) wherein the locking lever support pin axis 33 is also perpendicular to the bottom plate 3. The locking lever support pin 32 is expediently also screwed analogously to the rotary latch 13 by means of a slotted screw with the bottom plate 3. In addition, the locking lever support pin 32 is preferably arranged substantially centrally between the two longitudinal walls 5,6 and adjacent to the Schließboizenaussparung 9 on the other side compared to the rotary latch bearing pin 15.

For actuation of the rotary latch 13, a Sperrhebelumfangswandung 34 initially has a protruding actuating or locking lug 35, the two adjacent to each other and substantially radially with respect to the Sperrhebellagerungsbolzenachse 33 extending locking nose flanks 36,37 and a Sperrnasenrückwandung 38, the two locking nose flanks 36th 37 connects to each other and which preferably extends in relation to the locking lever mounting pin axis 33 substantially in the circumferential direction.

Furthermore, the locking lever 31 on a drive projection or driving projection 39 which is integrally formed on a locking lever top 40 and protrudes from this. In particular, the drive projection 39 is integrally formed on a Sperrhebelbetätigungsarm 41 of the locking lever 31, the first hook, or arcuately first from the Sperrhebellagerungsbolzenachse 33, for example radially, away and then makes a bend or a bow so that he then in essential in Circumferential direction with respect to the locking lever bearing pin axis 33 extends. The drive projection 39 is preferably arranged substantially diametrically opposite with respect to the Sperrhebellagerungsbolzenachse 33 for locking lug 35 and has a suitably flat Sperrhebelantriebsfläche 42 which is arranged perpendicular to the locking lever top 40 and the end of the Sperrhebelbetätigungsarmes 41 and the rotary latch 13 away.

Next, the locking lever 31 has a Sperrhebelanschlagarm 43, seen in the circumferential direction of the locking lever 31 between the Sperrhebelbetätigungsann 41 and the locking lug 35 is arranged, and preferably has a substantially T-shaped course. In particular, the lock lever stop arm 43 initially extends from the lock lever support pin axis 33, e.g. radially, and then divides into two T-pieces 43a, 43b, wherein the Sperrhebelbetätigungsarm 41 adjacent T-piece 43a end and outside with respect to the Sperrhebellagerungsbolzenachse 33, preferably flat, stop surface 44 has. The stop surface 44 is expediently aligned perpendicular to the locking lever upper side 40 and arranged such that it is parallel to a transverse inner wall 8a of the transverse wall 8 in a non-actuated position of the locking lever 31 and rests against this (Figure 2). The Querinnenwandung 8a thus serves as an abutment for the rotational movement of the locking lever 31 about the Sperrhebellagerungsbolzenachse 33, wherein a spring, in particular a locking lever torsion spring 61 (Figure 8) is present, which has the tendency to rotate the locking lever 31 in its non-actuated stop position, so to rotate him opposite to a Sperrhebelbetätigungsdrehrichtung T (Fig.1,4).

According to the invention, the rotary latch lock 1 also has an actuating mechanism for the locking lever 31, with which the locking lever 31 manually by means of a corresponding tool, in particular by means of a wrench and / or a screwdriver or a coin is actuated. As a wrench is referred to hand tools, more precisely screwing, with which you can tighten or solve fasteners such as screws and nuts or the like with different drive profiles (eg external hex, square). Wrenches are placed on the drive profiles eg recesses on the lateral surface of the connecting elements and actuated in the direction of rotation. Screwing tools, the front side in, or on the drive profile (eg slot, hexagon socket) the fasteners are inserted and operated in the direction of rotation called screwdriver.

The actuating mechanism thus has a drive element which has at least one drive profile for actuation by means of a corresponding tool, in particular by means of a wrench and / or a screwdriver. In this case, the drive element is preferably a drive shaft 48 with an outer edge profile, at least in sections, for example. Outer edge profile, external striking profile, external square profile, or external hexagonal profile 49 for actuation by means of an open-end wrench or a ring wrench. Furthermore, the drive shaft 48 expediently additionally on the front side, on a drive end face 53 on a drive slot 50 in the form of a longitudinal slot, which serves for selectively actuating the drive shaft 48 by means of a slot screwdriver. According to the invention, however, the drive shaft 48 may also have, for example, an external square profile and / or a cross slot and / or an internal hexagonal profile on the face side. The key width of the external hexagonal profile 49 is preferably 12 to 22 mm, preferably 13 to 17 mm.

The drive shaft 48 is further rotatable about its drive shaft axis 51 and otherwise immovably connected to the lock case 2, in particular, the Schließbolzenausnehmung 9 having longitudinal wall 6 on the lid 4 protruding bearing tabs 52 on which the drive shaft 48 is fixed. For this purpose, the bearing tab 52 has a cylindrical recess (not shown) and the drive shaft 48 on a drive end face 53 opposite Lagerungsstirnseite 54 a cylindrical bearing pin (not shown) with the same diameter, which is inserted through the recess. On the outside with respect to the bearing tab 52, a washer 59 and a rivet 57 are provided, by means of which the drive shaft 48 and the lock case 2 are fixed in the axial direction with respect to the drive shaft axis 51 to each other.

Furthermore, a substantially plate-shaped drive lever 55 is provided as a further element of the actuating mechanism on the Lagerungsstirnseite 54, which is so connected to the drive shaft 48, that the rotational movement of the drive shaft 48 is transferable to the drive lever 55, so this with the drive shaft 48 to the Drive shaft axis 51 is driven in connection. For this purpose, the elongated and substantially plate-shaped drive lever 55 at one end Drive lever bearing recess (not shown), with which it is plugged onto the drive shaft 48 such that the bearing tab 52 between the drive lever 52 and washer 59 is arranged. The rotationally secure connection of the drive lever 55 to the drive shaft 48 is effected, for example, by an internal square profile of the drive lever bearing recess and an associated external square profile (not shown) on the drive shaft 48. Furthermore, the drive lever 55 is preferably aligned substantially parallel to the longitudinal walls 5, 6.

To actuate the locking lever 31, the drive lever 55 in its Antriebshebelumfangswandung 105 also has a drive lever actuating lug 60 (Figure 3.5). The drive lever operating nose 60 abuts on the blocking lever drive surface 42 of the drive projection 39, so that the locking lever 31 is drivably connected to the drive lever 55 in the blocking lever operating direction of rotation T. In addition, the drive lever 55 has in its Antriebshebelumfangswandung 105 a Antriebshebelanschlagnase 109 which is directed towards the transverse wall 8 and in non-actuated position against a Querinnenwandung 8a, which thus serves as an abutment.

In the area of the drive lever stop nose 109 and the drive lever actuating nose 60, the drive lever 55 also expediently has a course which is inclined slightly toward the drive end face 53 of the drive shaft 48.

The mode of operation of the rotary latch lock 1 according to the invention in accordance with the first embodiment will now be explained in more detail below:

In an open position of the rotary latch lock 1, the locking pin 10 is initially outside of the lock case 2. The locking lever 31 is under the pressure of the locking lever torsion spring 61 with its stop surface 44 of the Sperrhebelanschlagarmes 41 on the transverse inner wall 8a. As a result, the drive lever 55 is pressed by the locking lever 31 via the pressing on the drive lever actuating lug 60 drive projection 39 with its Antriebshebelanschlagnase 109 to the transverse inner wall 8a. By the force of the rotary shaft torsion spring 29, the rotary latch 13 is arranged so that its stop edge 30 on the transverse inner wall 7a, rests (Figure 4). In this position, the locking lug 35 of the locking lever 31 and the rotary latch detent projection 62 are not in operative connection with each other and the groove 19 of the rotary latch 13 is arranged open to the locking pin recess 9 in the longitudinal wall 6 (not shown).

If the flap of the vehicle is closed, the locking pin 10 is inserted from the longitudinal wall 6 ago in the locking pin recess 9 and presses against the front latching nose flank 63a of the front latching nipple 63. Thus, the catch 13 against the pressure of the rotary shaft torsion spring 29 to the rotary latch bearing pin axis 16 in Direction of Drehfallenschließdrehrichtung S, pivoted so that the locking lug 20 begins to engage behind the locking pin 10 from the side of the longitudinal wall 6 ago. In the course of this rotational movement of the rotary latch detent projection 62, in particular the rear latching nose flank 64 b of the rear detent 64 on the locking lug 35, in particular on the front locking nose flank 36, whereby the locking lever 31 about the locking lever bearing pin axis 33 against the force of the locking lever torsion spring 29 in the Sperrhebelbetätigungsdrehrichtung T is pivoted until the locking lug 35 engages in the Drehfallenrastausnehmung 25 and the front locking nose flank 36 abuts the front Rastausnehmungsflanke 26 and the Sperrnasenrückwandung 38 on the rear Rastausnehmungsflank 27 (pre-catch or safety catch, Fig.1,2). By locking the locking lever 31 is rotated back to its original position, in which it rests under the pressure of the locking lever torsion spring 61 with its stop surface 44 of the Sperrhebelanschlagarmes 41 on the transverse inner wall 8a. The rotary latch 13 is now locked by the locking lever 31 and can not be rotated by the force of the rotary shaft torsion spring 29 opposite the rotary latch closing direction of rotation S. In this case, the locking lug 20 is rotated so far that the locking bolt 10 between the locking pin recess 9 and the groove 19, in particular one of the rotary latch 13 opposite Aussparungsseitenwandung 65, is included and can not escape from it (the locking pin 10 in safety catch is dashed in Fig.6 indicated).

If the catch 13 is further rotated by the pressure of the latch bolt 10 on the rear Auskhlungsseitenwandung 24 in Drehfallenschließdrehrichtung S, the front Rastausnehmungsflanke 26 slides on the front locking nose flank 36, wherein the locking lever 31 is pivoted against the pressure of the locking lever torsion spring 61 again until a detent nose 66 of the front locking lug 63 is rotated past a front locking nose tip 67 past. Due to the force of the rotary torsion spring 29 is now the front latch nose flank 63 a of the front rotary latch detent 63 on the Sperrnasenrückwandung 38 is pressed so that the rotational movement of the rotary latch 13 is locked against the Drehfallenschließdrehrichtung S by the locking lever 31, wherein the locking lever 31 is again suitably in its initial position. As a result, the lock 1 is held in its fully closed position. In the fully closed position (FIG. 6), the locking bolt 10 is arranged completely in the groove 19 and is thus positively encompassed by the groove 19 and the recess wall 65 of the locking bolt recess 9.

To open the rotary latch lock 1 according to the invention from the safety catch (Fig.1,2) or from the closed position (Fig.6) is now the drive shaft 48 and with this the drive lever 55 by means of a screwdriver which engages in the slot 50 or by means of a wrench which engages the hexagon socket 49, about the drive shaft axis 51 in a drive shaft actuation direction of rotation U (Fig.3,5,8) rotated so that by means of the drive lever operating nose 60, the drive lever 55 engages the locking lever drive surface 42 of the drive projection 39 and the locking lever 31 to the Locking lever bearing pin axis 33 against the pressure of the locking lever torsion spring 61 in Sperrhebeibetätigungsdrehrichtung T is pivoted (Figure 4), as soon as the front Sperrnasenkante 67 has slid past the Rastnasenspitze 66 of the front latching nose 63 and a Rastnasenspitze 106 of the rear locking lug 64, the catch 13 is unlocked and snap, driven by the power of the D Rehfederendrehfeder 29, automatically back to their opened starting position (Figure 4). The locking pin 10 is thereby pressed out of the lock case 1 addition. After releasing the drive shaft 48, the locking lever 31 driven by the pressure of the locking lever torsion spring 61 and the drive lever 55 driven by the drive shaft 48 through the locking lever 31 back into their non-actuated starting position back.

According to a second embodiment of the invention (Fig.9-17), the rotary latch lock 1 according to the invention two plate-shaped rotary traps 13a, b, which are rotatably mounted analogously to the first embodiment, each on a preferably hollow cylindrical trained rotary latch bearing pin 15, wherein the Drehfallenlagerungsbolzenachsen 16 also perpendicular to the bottom plate 3 are. The two rotary latch bearing bolts 15 are each arranged in the vicinity of the locking pin recess 9 having longitudinal wall 6 and symmetrically with respect to the recess center plane 11 of the rotary latch lock 1 from each other. The two Rotary traps 13a, b extend in turn parallel to the base plate 3 and slightly spaced from this. On each rotary latch 13a, b is in each case formed a locking lug 20 and a groove 19 adjacent thereto in the circumferential direction. The substantially semicircular grooves 19 of the two rotary traps 13 are arranged facing each other and in turn serve to accommodate the perpendicular to the bottom plate 3 extending and cylindrically shaped locking pin 10. In an open lock position (Fig.9,10) pass through the locking lugs 20 in the locking bolt recess 9 having longitudinal wall 6 provided, perpendicular to the recess center plane 11 extending slot (not shown) and are laterally beyond the longitudinal wall 6 addition. The slot is also formed symmetrically to the recess center plane 11 and extends parallel to the bottom plate 3 and seen from this approximately more than the amount of thickness of the two rotary traps 13 in the longitudinal wall 6 inside. The slot also has, preferably perpendicular to the bottom plate 3 aligned, slot edges (not shown), which serve as stop edges for each of the respective groove 19 opposite Riegelasenrückwandung 67, which will be explained later.

Furthermore, the peripheral wall 21 of the rotary traps 13 each three adjacent seen from the groove 19 from first, second and third Drehfallenrastnasen 68; 69, 70, respectively adjacent to the groove 19 and on the other side of the groove 19 as the locking lug 20th are arranged. The three rotary latch latches 68; 69; 70 each include a forward, longer, flatter lug catch lug flank 68a; 69a; 70a and a rear, shorter, steeper luff catch lobe flank 68b; 69b; 70b.

In addition, in each case a first, expediently V-shaped rotary latch detent recess 71 is formed between the first and the second rotary latch detent nose 68; 69, which is formed undercut due to the design of the two rotary detent detent nose flanks 68b; 69a. A second, also suitably V-shaped, Drehfallenrastausnehmung 72 is formed between the second and the third Drehfallenrastnase 69; 70, in particular between the short edge 69b of the second rotary detent lug 69 and the long edge 70a of the third rotary detent lug 70.

in the Drehfallenumfangswandung 21 is also provided in each case a projection 73 which is expediently arranged approximately opposite to the groove 19. The projections 73 serve to support the rotary twist springs or rotary coil springs 29 (Fig.12,14,16), which are arranged around the rotary latch bearing bolts 15 around and are supported by a first spring leg 29a on the projections 73 and a second spring leg 29b on a longitudinal inner wall 6a of the longitudinal wall 6. The rotary latch springs 29 have an endeavor to keep the rotary latches 13 in the open position (FIGS. 9, 10, 12), ie to push apart the latching lugs 20 pointing towards each other or to the latching lug back walls 67 against the slot edges of the slot in the longitudinal wall 6 to press.

For actuating the two rotary latches 13a, b, the rotary latch lock 1 according to the second embodiment has a pawl 74, which holds the rotary latches 13a, b in a closed position (FIG.12,13) or in a pre-latched position (safety catch) (not shown) the two rotary latches 13a, b releases (FIG. The pawl 74 is also plate-shaped, e.g. made of steel, formed and extends parallel to the bottom plate 3, wherein it has a substantially L-shaped curve with a longer leg or Drehfallensperrabschnitt 75 and a shorter leg or pawl drive portion 76. In the transition region from the rotary latching portion 75 to the pawl drive portion 76 is a continuous Bore 77 is provided, with which the pawl 75 is rotatably mounted on a, preferably hollow cylindrical, pawl support pin 78 about a latch bearing pin axis 79. In this case, the latch bearing pin 78 is also firmly connected to the bottom plate 3 and the latch bearing pin axis 79 is aligned perpendicular to the bottom plate 3. In addition, the latch support pin 78 is arranged in a corner region formed by the transverse wall 8 and the longitudinal wall 5, wherein the rotary latch portion 75 extends substantially parallel to the longitudinal walls 5,6 and the pawl drive portion 76 substantially parallel to the transverse walls 7,8.

The rotary latch portion 75 has an integrally formed latch detent projection 80 on the end, which is designed to the rotary trays 13 pointing and two end edges 81,82 and rotary latch side, the front edges 81,82 connecting longitudinal edge 83, wherein in the longitudinal edge 83 a Längskantenauskehlung 84 is introduced so that each a latch detent nose 85,86 is formed. With the pawl latching noses 85,86 of the latch detent projection 80 is in the open position initially on the rotary latch circumferential wall 21 of the two rotary traps 13 at. For this purpose, the pawl 74 is so spring-loaded by a spring, in particular a pawl torsion spring 87 (Figure 12) arranged that the pawl detent projection 80 is pressed against the two rotary latches 13a, b, Thus, the pawl 74 is driven opposite to a pawl operating direction W (Fig.9,10,13).

Furthermore, the pawl 74 at the end of the pawl drive portion 76 in a Klinkenumfangswandung 90 a pawl drive nose 88 (Fig.9,12), which has a pawl drive edge 89 which is formed facing the transverse wall 8.

The rotary latch lock 1 according to the second embodiment of the invention also has an actuating mechanism for the pawl 74, with which the pawl 74 manually by means of a tool, in particular by means of a wrench and / or a screwdriver is actuated. For this purpose, the actuating mechanism also has, as drive element, preferably a drive shaft 48 according to the first described embodiment, for which reason its design is not discussed in detail here. Only the bearing tabs 52 is not attached to the longitudinal wall 6, but on the lid 4, preferably formed on these in the second embodiment. In addition, the drive lever 55a according to the second embodiment has a slightly modified spatial shape as compared with the drive lever 55 according to the first embodiment. Specifically, the drive lever 55a has a plate-shaped drive lift portion 91 which extends substantially parallel to the longitudinal walls 5,6 and has the drive lever storage recess (not shown). To the drive lever bearing portion 91, a drive arm 92 is formed, which extends from the plate-shaped drive lever bearing portion 91 substantially perpendicular away in the direction of the drive end face 53 of the drive shaft 48 and in a view in a direction perpendicular to the drive lever bearing portion 91 has an angled course (Figure 11, 14:15). As a result, viewed from the drive lever mounting portion 91 at the end and outside of the drive arm 92, initially a flat outer surface 104 is formed, which merges into a flat output surface 93 via an output or deflecting edge 99. The output surface 93 and the output edge 99 serve to drive a plate-shaped coupling lever 94, which will be discussed in more detail below.

Furthermore, the drive lever 55a on the drive lever bearing portion 91 a stop arm 111 which abuts upon actuation of the drive lever 55a on the bearing lobes 52, which thus serves as an abutment for the rotational movement of the drive lever 55a in drive lever actuating direction of rotation U.

The elongated coupling lever 94 is used to actuate or to drive the pawl 74 and thus is both with this so also with the drive lever 55 in operative connection or can be brought into operative connection with them. For this purpose, the plate-shaped coupling lever 94 is aligned substantially parallel to the two longitudinal walls 5,6 and rotatably mounted about a coupling lever pivot axis 95, in particular rotatably connected to the longitudinal wall 6, wherein the coupling lever pivot axis 95 is perpendicular to the two longitudinal walls 5,6. Furthermore, the coupling lever 94 has a coupling lever operating nose 96, which is arranged inside the lock box 2, and a coupling lever drive section 97 substantially diametrically opposite to the coupling lever pivot axis 95, in the region of which a coupling lever peripheral wall 108 faces a planar drive sliding surface 98 facing the drive lever 55a wherein the drive section 97 is preferably slightly widened in the region of the drive sliding surface 98. The drive sliding surface 98 is also aligned perpendicular to the longitudinal walls 5,6. At the Antriebsgleitfläche 98 of the drive lever 55 engages with its output edge 99 and its flat Abtriebsgleitfläche 93 and slides when actuated along it.

Furthermore, the drive portion 97 expediently at the end a continuous, perpendicular to a coupling lever side surface 94 a extending bore 100, which serves for attaching a connecting rod for the operation of the lock 1 from the inside by means of a handle, if this is additionally desired.

In addition, the coupling lever 94 is so drivably connected to the pawl 74 against a Kopplungsbebetätätigungsdrehrichtung V that the Kopplungsbetbetbetigungsnase 96 is pressed with a nose stop surface 102 serving nose against a Querinnenwandung 8a, thus as an abutment for the rotational movement of the coupling lever 94 about the coupling lever pivot axis 95th opposite to the coupling lever actuating direction of rotation V and thus indirectly also for the rotational movement of the pawl 74 opposite to the pawl actuating direction of rotation W is used. Furthermore, the coupling lever actuating nose 96 has a nose-engaging surface 103 (Fig. 14) opposite the nose stop surface 102, which in turn serves to actuate the pawl 74 counter to the force of the pawl torsion spring 87. In addition, there may also be a coupling lever torsion spring (not shown) with which the coupling lever 94 opposite to the coupling lever actuating direction V drivable communicates.

The mode of operation of the rotary latch lock 1 according to the invention in accordance with the second embodiment will now be explained in more detail below:

In an open position of the rotary latch lock 1, the locking bolt 10 is located outside the lock case 2 between the two recesses 19 of the two rotary latches 13a, b. The locking lugs 20 pass through the slot, not shown, in the lock case 2 and are pressed by the force of the rotary shaft torsion springs 29 with their locking lug rear walls 67 against the slot edges serving as a stop and perpendicular to the base plate 3. Furthermore, the pawl 74 is under the pressure of the pawl torsion spring 87 with the pawl latching lugs 85,86 of the latch detent projection 80 on the Drehfallenumfangswandung 21 of the two rotary traps 13a, b in the region of the short edges 70b of the third Drehfallenrastnasen 70 (not shown).

The coupling lever 94 is initially unactuated with the nose stop surface 102 of the Kopplungshebelbetätigungsnase 96 on the Querinnenwandung 8 a, the Klinkenantriebskante 89 of the pawl 74 abuts the actuating surface 103 of the coupling lever actuating nose 96 and the pawl 74 and the coupling lever 94 by the force of the pawl spring 87 in the be held depressed position (Fig.14). The drive lever 55a, in turn, is arranged such that the flat outer surface 104 is adjacent and substantially parallel to the drive surface 98 of the coupling lever 94, but preferably not in contact therewith, the output surface 93 of the drive lever 55a being directed away from the drive surface 98 ,

When the locking pin 10 is now inserted into the locking pin recess 9, it is pressed against the front rotary latch locking lug flanks 68a of the first rotary latch lugs 68 and the rotary latches 13a, b are counter-urged against the pressure of the rotary latch springs 29 and partly the pawl spring 87 respectively in the rotary latch closing direction Sa; Rotary latch bearing pin 15 is pivoted so that the locking lugs 20 are moved towards each other and the locking pin 10 begin to enclose. Due to the rotational movement also reach the latch detents 85,86 in the region of the rear locking recesses 72 and rest there due to the spring pressure of the pawl spring 87 a (safety catch). In this position are the two Rotary latches 13a, b are locked and can no longer be rotated by the force of the rotary lobe torsion springs 29 in opposition to the latches closing directions Sa; b. In this case, the locking lugs 20 are arranged so far turned to each other that the locking pin 10 can no longer escape from the area between the grooves 19 and the rotary latch lock 1 only movable by a certain amount, but already locked, so it is no longer open. The coupling lever 74 and the drive lever 55a remain in their previous position.

If the rotary latches 13a, b are further rotated by the pressure of the locking bolt 10 on the grooves 19 in each case in Drehfallenschließdrehrichtung Sa, b, the pawl latching lugs 85,86 get into the respective front recesses 71 of the rotary traps 13a, b and rest there due to the spring force of the pawl torsion spring 87, so that the rotary latches 13a, b are locked against a rotational movement against the rotary latch closing directions Sa, b. The rotary latches 13a, b are then in the locked, fully closed position (FIGS. 12, 13), the locking bolt 10 being arranged in a form-fitting manner in the recesses 19 and being firmly gripped by the rotary latches 13a, b. As a result, the lock 1 is held in the closed and locked position.

To open the rotary latch lock 1 according to the invention from the pre-latched safety catch (not shown) or from the closed position (Fig.12,13) is now the drive shaft 48 and with this the drive lever 55a by means of a screwdriver which engages in the slot 50 or by means of a wrench , which engages the hexagon profile 49, rotated about the drive shaft axis 51 in drive shaft rotation direction U, so that first the output edge 99 and in the further course of the rotational movement, the drive surface 98 of the drive arm 92 engages the drive surface 98 of the coupling lever 94 and slides along it. Due to the angled course of the drive arm 92, the coupling lever 94 is thereby pivoted about its coupling lever rotational axis 95, so that the nose stop surface 102 is moved away from the transverse inner wall 8a and the actuating surface 103 of the coupling lever actuating nose 96 engages the pawl drive edge 89 of the pawl 74 and thus the pawl 74 about its pawl support pin axis 79 against the force of the pawl torsion spring 87 is rotated or drives so that the two pawl latches 85, 86 are moved away from the rotary traps 13. As soon as the pawl latching lugs 85, 86 are no longer in engagement with the front or rear latching recesses 70, 71 (depending on the closed position), the rotary latches 13a, b are unlocked and automatically snap back into their opened starting position by the force of the rotary shaft torsion springs 29 (FIG. The locking pin 10 is thereby pressed out of the lock case 2 by the recesses 19,

After releasing the drive shaft 48 and this and with it the drive lever 55a snaps back by the pressure of a drive shaft torsion spring 110 in the starting position. As a result, the pawl 74 by the force of the pawl spring 87 spring back into its original position, whereby the coupling lever 94 is driven by the pawl 74 is rotated back to its original position.

The rotary latch lock according to the invention can be actuated in a simple manner and due to the lever mechanism of drive lever and optionally coupling lever with little effort. The fact that a suitable tool for unlocking is necessary to prevent the rotary latch lock unlocked by unauthorized persons simply by the operation of a lever or a push button and the flap can be opened. Furthermore, the structure of the actuating mechanism of the rotary latch lock according to the invention is very simple and has only a few components, so that both the assembly and the manufacture of the rotary latch lock according to the invention is inexpensive.

In summary, the rotary latch lock according to the invention has the advantages that hoods and flaps can be opened without a complex up and lockable actuating mechanism with the help of simple hand tools. This results in a cost-producible version that is simple and provides a degree of security.

Of course, it is also within the scope of the invention according to patent application DE 10 2005 045 808.4 each catch to provide a pawl which can be actuated, for example by means of an actuating lever, wherein the actuating lever can be in operative connection with the actuating mechanism according to the invention, that is operable with this.

Furthermore, the safety catch can be dispensed with, for example, by appropriate design of the rotary latch detent projection or fewer rotary detent detents.
