[0001] FITTING ARRANGEMENT FOR LOCKING A
[0002] SLIDING WING
[0003] The present invention relates to a fitting arrangement for locking a sliding wing, such as the wing of a lift-sliding door or a lift-sliding window.
[0004] In order to be able to lock such a sliding sash, such as the sash of a lift and slide door or a lift and slide window, to a frame in its closed position, a bolt latch is usually provided on the frame, which the drive rod of the sash's fitting arrangement engages behind in its locked position. Specifically, for this purpose, an elongated opening is formed in the drive rod of the fitting arrangement, which opening has a slot-like or elongated first opening section with a first width and a second opening section with a second width that is greater than the first width. When the sash is closed, the bolt latch first moves into the slightly wider second opening section, whereupon, when the sash is lowered, the bolt latch moves into the slot-like or elongated first opening section.elongated first opening section, which then engages with its edges behind the bolt head of the bolt latch, thereby securing the sash to the frame. Likewise, in the faceplate, along which the drive rod is guided so that it can be moved translationally between its locking and unlocking positions, an elongated hole is formed, which is partially aligned with the opening of the drive rod. The elongated hole in the faceplate allows the sash to be lowered when the bolt latch on the frame extends through the elongated hole in the faceplate into the opening of the drive rod when the sliding sash is in the closed position.
[0005] Recently, other hardware arrangements for locking a sliding sash to the frame have also become known, which do not feature a bolt lock on the frame. Instead, a corresponding locking element, such as a hook or bolt lock, can be provided on the sash itself, which, when the sash is closed, can be engaged with a striker provided on the frame, thus securing the sliding sash to the frame.
[0006] However, to provide such locking elements on the sash element, specially designed hardware assemblies are required, specifically designed for attaching the respective locking element to the sliding sash. Depending on the type of locking mechanism or the respective locking element, different hardware assemblies must be manufactured and maintained.
[0007] The invention is therefore based on the object of specifying a fitting arrangement for locking a sliding sash, which can be used regardless of the type of locking - for example bolt bolt on the frame, hook bolt on the sash or bolt bolt on the sash.
[0008] This object is achieved with a fitting arrangement having the features of claim 1 and, in particular, in that the fitting arrangement comprises a locking element which is drivingly connected to the drive rod by means of a coupling element and which extends, at least in the locking position, through both the opening of the drive rod, in particular through its first opening section, and through the elongated hole opening of the faceplate. According to the invention, it is thus provided, in a sense, to upgrade a conventional fitting arrangement with a locking element which, when the sliding sash is in the closed position, can be brought into engagement with a locking part provided on the frame. For this purpose, the locking element extends through both the opening of the drive rod and through the elongated hole opening of the faceplate.If a conventional fitting arrangement is mentioned here, this is characterized by a faceplate and a drive rod which is guided thereon so as to be translationally displaceable between a locking position and an unlocking position, in which an opening is formed which is at least partially aligned with an elongated hole opening of the faceplate, which opening has a slot-like or elongated first opening section with a first width perpendicular to the longitudinal extent of the drive rod and a second opening section which merges into the first opening section at one end and has a second width which is greater than the first width.
[0009] The opening in question in the drive rod, through which the locking element extends at least in the locking position, is thus, in a sense, an elongated hole opening with a first width, wherein the elongated hole opening has an enlarged region at one end in the form of the second opening section with a second width. The second opening section can, for example, be a circular opening section whose diameter corresponds to the second width, or else a further elongated hole opening that extends as a continuation of the first opening section or the elongated hole opening with the first width and that has the second width.Since the locking element of the upgraded fitting arrangement is connected to the drive rod in a drive-effective manner, the locking element can be adjusted in the closed position of the sash by actuating the drive rod and thus brought into engagement with a locking part on the frame in order to secure the sliding sash to the frame.
[0010] In contrast, in a lift-and-slide sash with a bolt bolt fixedly attached to the frame in the conventional manner, upgrading the hardware assembly with a locking element in the manner according to the invention can be omitted. Thus, to lock the lift-and-slide sash to the frame, the bolt bolt located on the frame can be engaged behind the edges of the slot-like first opening section of the drive rod opening. Thus, depending on the locking type, one and the same hardware assembly can be used, eliminating the need to manufacture and maintain different hardware assemblies.
[0011] In the following, preferred embodiments of the present invention will be discussed, whereby further embodiments can also be derived from the dependent claims, the description of the figures and the drawings themselves.
[0012] Thus, according to one embodiment, the locking element can be designed as a hook or a hook bolt that can be pivoted about an axis between a disengaged position corresponding to the unlocked position of the drive rod and an engaged position corresponding to the locked position of the drive rod. For this purpose, the coupling element has a rack section that meshes with a gear section provided on the hook bolt. The hook bolt is thus drive-effectively coupled to the drive rod via a rack and pinion drive. In order to be able to pivot the hook bolt between its engaged position and its disengaged position, it is therefore not necessary to form a rack section or toothing on the existing fitting arrangement or on its drive rod that meshes with the gear section of the hook bolt in order to be able to adjust it.Rather, the fitting arrangement itself can remain unchanged, since the rack section is formed on the coupling element, which is coupled to the fitting arrangement known per se or its drive rod.
[0013] According to a further embodiment, the rack section can be provided to run parallel to the drive rod, with the axis about which the hook latch can be pivoted being located between the drive rod and the rack section. Thus, viewed from the drive rod, the rack section engages behind the hook, so to speak.
[0014] If the hook has a substantially U-shaped configuration with a hinged end, where the axle is located, and an opposite free end, then, due to the fact that the hook bolt is, as it were, engaged behind by the rack section in the manner described above, the free end of the hook bolt, upon reaching the engaged position, exhibits a movement component that is oriented opposite to the direction of movement of the drive rod upon reaching the locked position. Thus, if the drive rod is moved downwards from its unlocked position toward its locked position, the free end of the hook bolt, upon reaching its engaged position, exhibits a movement component that is directed upwards. The U-shaped hook bolt must therefore be oriented in such a way that the "U" formed by the hook bolt is open upwards in the engaged position.that the opening of the "U" is at the top in the engaged position. Since the rack section of the coupling element is spaced from the drive rod according to the above explanations, according to a further embodiment, the coupling element can have a coupling section that bridges the distance between the drive rod and the rack section and that has a free end that is coupled to the drive rod. The coupling element can thus be a substantially L-shaped component, with the two legs of the "L" being formed, on the one hand, by the rack section and, on the other hand, by the coupling section.
[0015] To ensure that the fitting assembly can be handled as a unit and, for example, the locking element does not have to be mounted as a separate component in the fitting groove, a further embodiment can provide for the hook bolt and the coupling element to be arranged between two side walls attached to the faceplate. The hook bolt can be pivoted about the axis on the side walls, and the coupling element is mounted on the side walls so that it can be displaced in the direction of the longitudinal extension of the rack section. For example, a guide groove can be formed in each of the side walls, into which the respective guide sections of the rack section engage, thus enabling the rack section to be displaced within the side walls.
[0016] According to yet another embodiment, it can be provided that the rack section, in the engaged position of the hook bolt, has a lost motion or a certain amount of play relative to the hook bolt, which allows adjustment of the rack section with play between a first and a second lost motion position. In particular, it can be provided that, in the engaged position of the hook bolt, a tooth formed on the hook bolt engages with play in an associated recess or in a corresponding tooth gap in the rack section, wherein the play is large enough that, in the first lost motion position, meshing of the further teeth of the gear section with the teeth of the rack section is possible, and that, in the second lost motion position, meshing of the further teeth of the gear section with the teeth of the rack section is prevented.
[0017] In the second dead-motion position, the top surfaces of the teeth of the gear section meet the top surfaces of the teeth of the rack section, so that the gearing or rack drive locks. If, for example, the sash is lifted during a burglary attempt, the hook bolt is prevented from pivoting from its engaged position to its disengaged position, which in turn is due to the rack drive locking in the manner described above. Only when the rack section is moved against the force of gravity from its second dead-motion position to its first dead-motion position by actuating the drive rod do the teeth of the gear section of the hook bolt mesh with the teeth of the rack section, so that upon further actuation of the drive rod, the hook section can be rotated into its disengaged position in the desired manner.
[0018] Contrary to the previously described embodiment in which the locking element is designed as a hook bolt, according to a further embodiment it can be provided that the locking element is designed as a mushroom head pin which is fixedly mounted in the opening of the drive rod and remains there, regardless of whether the drive rod is in its locked or unlocked position.
[0019] To attach the mushroom-head pin in the opening of the drive rod, a filler piece can be used as a coupling element according to another embodiment. This filler piece supports the mushroom-head pin and fits snugly into the opening of the drive rod. The fitting arrangement can thus be very easily upgraded by installing the filler piece with the attached mushroom-head pin in the opening of the drive rod.
[0020] According to a further embodiment, the filler piece can be secured in the opening of the drive rod by means of the mushroom-head pin itself. For this purpose, the mushroom-head pin has a support section spaced from its mushroom head at the end, which is tensioned against the edges of the slot-like or elongated first opening section of the drive rod by means of a screw element such as a nut, which is screwed onto the end of the mushroom-head pin opposite the mushroom head. The mushroom-head pin thus functions, in a sense, as a type of screw, by means of which the filler piece with the mushroom-head pin provided therein is screwed tightly into the slot-like first opening section.
[0021] Contrary to the previously described embodiments, in which the hook bolt is drivingly coupled to the drive rod via a rack and pinion drive, a further embodiment can provide for the coupling element connected to the drive rod to be drivingly coupled to the hook bolt via a drive pin. In other words, the coupling element and the hook bolt are pivotally connected to one another via the drive pin. The movement of the coupling element is thus transmitted to the hook bolt via the drive pin, so that the hook bolt is pivoted between its disengaged and engaged positions via the drive pin when the drive rod is moved between its unlocked and locked positions.
[0022] In particular, it can be provided that the driver pin extends through a first elongated hole in the coupling element, oriented perpendicular to the direction of movement of the drive rod, and a second elongated hole in the hook bolt, which is oriented such that the axis of the hook bolt is in continuation of the longitudinal extension of the second elongated hole. The driver pin can thus move translationally relative to both the coupling element and the hook bolt, so that, as desired, no constraints arise between the hook bolt and the coupling element when the drive rod and thus the coupling element are moved.
[0023] According to a further embodiment, it can be provided that a guide slot is formed in at least one side wall, but preferably in both side walls between which the hook bolt and the coupling element are located, which guide slot slidably accommodates the driver pin and preferably comprises a first elongated hole section aligned parallel to the direction of movement of the drive rod. The guide slot thus forms a positive guide, by means of which the driver pin is positively guided between a position corresponding to the engaged position and a position corresponding to the disengaged position of the hook bolt when the drive rod, and via it the coupling element, is adjusted between the unlocked position and the locked position.
[0024] According to yet another embodiment, it can be provided that the first elongated hole section transitions at a first end into a second elongated hole section, which encloses an angle of between approximately 120° and 150° with the first elongated hole section and in which the driver pin comes to rest when the hook latch is in its disengaged position. Additionally or alternatively, the first elongated hole section can transition at a second end into a third elongated hole section, which encloses an angle of between approximately 120° and 150° with the first elongated hole section and in which the driver pin comes to rest when the hook latch is in its engaged position. In this embodiment, it is preferably provided that the end of the second and / or the third elongated hole section is further away from the drive rod than the first elongated hole section.Because the second slot section is angled relative to the first slot section, only a component of the movement of the driving pin is transferred to the hook bolt, which results in a slowing down of the rotational speed of the hook bolt when it approaches its disengaged position, while the drive rod or coupling element speed remains constant.
[0025] However, if the hook bolt reaches its engaged position, the hook bolt is pivoted slightly back towards its disengaged position due to the angled third slot section compared to the first slot section when the drive rod is moved fully into its unlocked position. In this position, the hook bolt cannot be pivoted directly back into its disengaged position, for example in the event of a break-in attempt, even if force is applied. To do this, the drive pin would first have to be pushed back into the first slot section. Due to the angled third slot section compared to the first slot section, the gear locks, meaning that the hook bolt itself cannot be forcibly pivoted directly back into its disengaged position.
[0026] In the following, the invention will now be described purely by way of example with reference to the figures in which:
[0027] Fig. 1 a, 1 b, 1 c show a conventional fitting arrangement without an additional locking element or with an additional locking element in the form of a hook bolt or a bolt bolt in a perspective view; Fig. 2a, 2b, 2c show the corresponding views of Fig. 1 a, 1 b and 1 c without the faceplate.
[0028] Fig. 3a, 3b, 3c show the fitting arrangement according to Figs. 1a, 1b and 1c in a sectional view;
[0029] Fig. 4a, 4b, 4c show the fitting arrangement of Fig. 1a, 1b, 1c in a view;
[0030] Fig. 5 shows perspective views of Fig. 2b and 2c with the locking element removed from the drive rod; and
[0031] Fig. 6, 7 and 8 show an embodiment in which the coupling element connected to the drive rod is drivingly coupled to the hook bolt via a driver pin.
[0032] In the following, a conventional fitting arrangement 10 is described with reference to Figs. 1a, 2a, 3a and 4a, which fitting arrangement can be upgraded with an additional locking element 30, 60 if required in the manner according to the invention. The fitting arrangement 10 has a faceplate 12, by means of which the fitting arrangement 10 can be mounted in a fitting groove of a sliding sash, such as a lift-and-slide sash (not shown), and by means of which the fitting groove is covered when the fitting arrangement 10 is in the mounted state. Furthermore, the fitting arrangement 10 has a drive rod 14, which is guided displaceably along the faceplate 12, specifically between a locking position and an unlocking position. As can be seen in particular from Fig. 2a, a plurality of elongated hole openings are formed in the drive rod 14, wherein the elongated hole opening designated here by the reference numeral "16" has an elongated orA slot-like first opening section 16a and a second opening section 16b, into which the first opening section 16a merges at one end and which has a greater width than the first opening section 16a. The elongated hole opening 16 is thus, in a sense, a single elongated hole with an elongated widening at its lower end. In other words, the elongated hole opening 16 is, in a sense, two elongated holes of different widths that merge into one another.
[0033] Furthermore, a coupling opening 18 is formed in the drive rod 14, the purpose and function of which will be discussed in more detail below. As can also be seen in particular from Fig. 1a, an elongated hole opening 20 is also formed in the faceplate 12, wherein this elongated hole opening 20 is aligned with a section of the elongated hole opening 16 of the drive rod 14 depending on the position of the drive rod 14; see, for example, Fig. 4a, from which it can be seen that in the locking position shown, the elongated hole 20 of the faceplate 12 is aligned with the first opening section 16a of the elongated hole opening 16 of the drive rod 14.
[0034] In the unlocked position of the drive rod 14, however, the second opening section 16b of the elongated hole 16 of the drive rod 14 is aligned with the elongated hole 20 of the faceplate 12, so that in this unlocked state, a bolt latch 22 fastened to a frame (not shown) can be inserted into the two aligned openings 16b, 20 when a lift / slide sash, on which the fitting arrangement 10 is located, is closed. If, in this closed state, the sash is lowered by moving the drive rod 14 from its unlocked position to its locked position, the position of the bolt latch 22 within the elongated hole 20 of the faceplate 12 changes. Likewise, in the locked position of the drive rod 14, the first opening section 16a of the elongated hole 16 of the drive rod 14 engages behind the two aligned openings 16b, 20.The two opposing edges of this opening section 16a engage the bolt head 24 of the bolt latch 22 (see, for example, Fig. 3a). This engagement of the bolt head 24 by the two opposing edge sections of the opening section 16a secures the sliding sash in its closed position to the frame. This corresponds to the known functionality of such a fitting arrangement 10.
[0035] In the following, a first embodiment will be explained with reference to Fig. 1b, 2b, 3b, 4b, in which the previously described fitting arrangement 10 has been upgraded by means of a locking element in the form of a hook bolt 30. The hook bolt 30 is a substantially U-shaped hook element arranged between two side walls 32 that run spaced apart and parallel to one another and are fastened to the faceplate 12. The hook bolt 30 has an end 36 hinged to the two side walls 32 and a free end 34 opposite the hinged end 36. In particular, the hook bolt 30 is pivotable about an axis 38 between its engaged position, which corresponds to the locking position of the drive rod 14, and a disengaged position, which corresponds to the unlocked position of the drive rod 14.In the engaged position, the hook bolt 30 extends through the elongated hole opening 16 of the drive rod 14 and in particular through the first opening section 16a of the elongated hole opening 16.
[0036] The coupling element 40 is also located between the two side walls
[0037] 32 and is mounted thereon for displacement parallel to the longitudinal extension of the drive rod 14, for which purpose an elongated slot 56 can be formed in each of the side walls 32, which slidably accommodates a guide section 58 formed on the coupling element 40. The guide slot thus formed can be seen in Figs. 1b and 2b as well as in the central illustration of Fig. 5.
[0038] In order to synchronize the movement of the hook bolt 30 with that of the drive rod 14, so that the engaged position of the hook bolt 30 corresponds to the locking position of the drive rod 14 and the disengaged position of the hook bolt 30 corresponds to the unlocking position of the drive rod 14, the hook bolt 30 is connected to the drive rod 14 by means of a coupling element 40 (see in particular Fig. 3b). The movement of the drive rod 14 is thus transmitted to the hook bolt 30 via the coupling element 40, as will be explained in more detail below.
[0039] The coupling element 40 is a component with a rack section 42 running parallel to the drive rod 14 and a coupling section 44 that bridges the distance between the drive rod 14 and the rack section 42 in which the axis 38 is located. The coupling section 44 has a free end 46 that positively engages the coupling opening 18 of the drive rod 14, so that the coupling element 40 is carried along by the drive rod 14. The movement of the coupling element 40 is transmitted to the hook element 30 via its rack section 42, for which purpose a gear section 48 is provided at its articulated end 36, the teeth of which mesh with those of the rack section 42, see Fig. 3b, in which, however, due to the sectioning, only a single tooth 50 of the gear section 48 is fully visible.The hook bolt 30 is thus drive-effectively connected to the drive rod 14 via the coupling element 40 and can thus be pivoted by actuating the drive rod 14 from its disengaged position, in which the free end 34 of the hook bolt 30 is located approximately below the axis 38, through the elongated hole 16 of the drive rod 14 and through the elongated hole 20 of the faceplate 12, until the free end 34 of the hook bolt 30 engages behind the bolt 52 of a locking part 54 on a not-shown frame, as shown in Fig. 3b. According to the invention, the already existing elongated hole openings 16, 20 of the faceplate 12 or the drive rod 14 are thus used to accommodate the hook bolt 30 in its locking position.
[0040] Due to the fact that the rack section 42 engages behind the gear section 38 of the hook bolt 30, starting from the drive rod 14, in order to engage with it, the free end 34 of the hook bolt 30 exhibits an upward movement component upon reaching the engaged position of the hook bolt 30, whereas the drive rod 14 is moved downward toward its locking position. Thus, a reversal of movement occurs between the direction of movement of the drive rod 14 and the free end 34 of the hook bolt 30, which is the reason why, in the embodiment shown here, the essentially U-shaped hook bolt 30 is oriented such that the opening of the "U" is at the top in the engaged position.
[0041] In order to prevent the hook bolt 30 from being forcibly pivoted from its engaged position into its disengaged position when a lift-slide sash equipped with the fitting arrangement 10 is forcibly lifted, the fitting arrangement 10 has a self-locking function which locks the fitting arrangement 10 and thus prevents the hook bolt 30 from being pivoted from its engaged position into its disengaged position by lifting the lift-slide sash.
[0042] To implement this self-locking function, the rack section 42 has a lost motion or a certain amount of play relative to the hook bolt 30 in the engaged position of the hook bolt 30, which allows a play-related adjustment of the rack section 42 between a first and a second lost motion position, into which the rack section 42 tends to be forced by gravity. For this purpose, it is provided in particular that the last tooth 50 of the gear section 48, in the engaged position of the hook latch 30, engages with play in a recess or tooth gap 51 of the rack section 42, this play being so large that in the first lost motion position, meshing of the further teeth of the gear section 48 with the teeth of the rack section 42 is possible and that in the second lost motion position, meshing of the further teeth of the gear section 48 with the teeth of the rack section 42 is prevented.
[0043] The play-related receptacle of the tooth 50 in the corresponding receptacle or tooth gap 51 is made possible by the fact that the tooth gap 51 in question has a dimension in the longitudinal direction of the rack section 42 that is approximately twice as large as the dimension of the tooth 50 measured in the longitudinal direction of the rack section 42. Therefore, if the rack section 48 is in its second lost motion position according to Fig. 3b, into which it is forced by gravity, the head surface of the next tooth 53 strikes the head surface of a tooth of the rack section 42, thereby preventing a violent pivoting of the hook latch 30.
[0044] Only when the drive rod 14 is slightly raised from its locking position and thus the rack section 42 is also slightly raised against the force of gravity from its second dead-movement position according to Fig. 3, the self-locking function of the fitting arrangement 10 is canceled, since in the first dead-movement position of the rack section 42 the tooth 53 no longer hits the head surface of a tooth of the rack section 42, but moves into the next tooth gap. In the following, a second embodiment will now be described with reference to Figs. 1 c, 2c, 3c and 4c, in which the fitting arrangement 10 known per se according to Figs. 1 a, 2a, 3a and 4a has been upgraded by means of a locking element in the form of a mushroom-head pin 60 which, in the locking position in the drive rod 14, extends through both the elongated hole opening 16 of the drive rod 14 and the elongated hole 20 of the faceplate 12.The mushroom head pin 60 is carried by a filler piece 62 serving as a coupling element through which the mushroom head pin 60 extends, see Fig. 3c and the right-hand illustration of Fig. 5.
[0045] As can be seen in particular from the right-hand illustration of Fig. 5, the filler piece 62 has a contour on its front side that essentially corresponds to the edge of the elongated hole opening 16 or the edge of the two opening sections 16a, 16b of the elongated hole opening 16 of the drive rod 14. The filler piece 62 can thus be fitted positively into the elongated hole opening 16 of the drive rod 14 and secured therein, for which purpose the mushroom-head pin 60 has a collar-like abutment section 66 spaced from its mushroom head 64, which abuts against the edge of the first opening section 16a of the elongated hole opening 16 of the drive rod 14; see Fig. 2c, for example. On the other hand, a nut 68 is screwed onto the end of the mushroom head pin 60 opposite the mushroom head 64, by means of which the abutment section 66 is clamped against the opposite edges of the first opening section 16a.
[0046] The mushroom-head pin 60 can thus be moved from its disengaged position into its engaged position via the drive rod 14, in which it engages behind a locking portion of a locking part provided on a window frame. With reference to Figs. 6, 7, and 8, an embodiment will now be described in which the hook bolt 30 is coupled to the coupling element 40 connected to the drive rod (only schematically indicated in Fig. 6) via a drive pin 70, not via a rack and pinion drive as in the embodiment according to Figs. 1b, 2b, 3b, and 4b. In this embodiment, too, the hook bolt 30 is a substantially U-shaped hook element arranged between two side walls 32 that are spaced apart and parallel to one another and are or can be attached to the faceplate (not shown).The hook latch 30 has an end 36 hinged to the two side walls 32 and a free end 34 opposite the hinged end 36. The hook latch 30 is thus pivotable about an axis 38 between its engaged position, which corresponds to the locking position of the drive rod 14, and a disengaged position, which corresponds to the unlocking position of the drive rod. As in the embodiment of Figs. 1b, 2b, 3b, and 4b, the hook latch 30 extends through the elongated hole 16 of the drive rod 14 and, in particular, through the first opening section 16a of the elongated hole 16 when it is in the engaged position.
[0047] The hook latch 30 is flanked on both sides by a coupling element 40. In other words, the two coupling elements 40 are located between the hook latch 30 and the respective side wall 32. The coupling elements 40 are essentially identical in design, which is why only the design of one of the two coupling elements 40 will be discussed below. The same applies to the side walls 32.
[0048] The coupling element 40 is slidably guided on the respective side wall 32 parallel to the longitudinal extent of the drive rod 14, for which purpose an elongated slot 72 is formed in the coupling element 40, through which the axis 38 extends, on which the hook latch 30 is pivotally mounted on the side walls 32. Furthermore, for the drive-effective coupling of the coupling element 40 to the drive rod 14, a nose 74 is formed on the coupling element 40, which is positively received in a corresponding slot 88 in the drive rod 14. The coupling element 40 is thus positively connected to the drive rod 14 and guided parallel to the drive rod 14 by the axis 38 extending through the slot 72 formed in the coupling element 40.
[0049] In order to synchronize the movement of the hook bolt 30 with that of the drive rod 14, so that the engaged position of the hook bolt 30 corresponds to the locking position of the drive rod 14 and the disengaged position of the hook bolt 30 corresponds to the unlocking position of the drive rod 14, the hook bolt 30 is drive-effectively coupled to the coupling element 40 connected to the drive rod 14 via the driver pin 70. In the specifically illustrated embodiment according to Figs. 6, 7 and 8, the driver pin 70 extends through a first elongated hole opening 76 in the coupling element 40, which is oriented perpendicular to the direction of movement of the drive rod 14, and a second elongated hole opening 78 in the hook bolt 30. The second elongated hole opening 78 is oriented such that the axis 38 of the hook bolt 30 is in continuation of the longitudinal extent of the second elongated hole opening 78.The driver pin 30 can thus move translationally relative to both the coupling element 40 and the hook latch 30, so that no constraints arise between the hook latch 30 and the coupling element 40 when the drive rod 14 and thus the coupling element 40 are moved. For example, if the coupling element 40 is moved downward from the unlocked position shown in Fig. 7, the driver pin 70 can slide along the elongated hole 78 of the hook latch 30 in the direction of the axis 38, since otherwise a pivoting movement of the hook latch 30 would be blocked.
[0050] As can also be seen from Fig. 6, a guide slot 80 is formed in the front side wall 32, wherein a corresponding guide slot can be formed in the rear side wall 32. The guide slots 80 formed in the two side walls 32 slidably accommodate the ends of the driver pin 70. The guide slot 80 thus forms a positive guide, by means of which the driver pin 70 is positively guided between a position corresponding to the engaged position of the hook latch 30 and a position corresponding to the disengaged position of the hook latch 30 (as shown in Figs. 6, 7 and 8) when the drive rod 14 and, via this, the coupling element 40 are adjusted between the unlocked position and the locked position.
[0051] Specifically, in the embodiment shown here, the guide slot 80 has a first elongated hole section 82 aligned parallel to the direction of movement of the drive rod 14. In this first elongated hole section 82, the driver pin 70 is guided over most of the pivoting movement of the hook latch 30 between its engaged position and its disengaged position.
[0052] At its upper end, the first elongated hole section 82 merges into a second elongated hole section 84, with which the first elongated hole section 82 forms an angle of between approximately 120° and 150°. The angle in question is selected such that the longitudinal extent of the second elongated hole section 84 coincides with the longitudinal extent of the elongated hole opening 78 of the hook bolt 30 when the latter is in its disengaged position as shown in Figs. 6, 7 and 8. Shortly before the drive rod 14 reaches the unlocking position, the driver pin 70 thus enters the second elongated hole section 84, with the result that only a movement component of the movement of the driver pin 70 is transmitted to the hook bolt 30, whereby, with a constant drive rod or coupling element speed, the rotational speed of the hook bolt 30 slows down as the latter approaches its disengaged position.At its lower end, the first elongated hole section 82 of the guide slot 80 also merges into a (third) elongated hole section 86, which also forms an angle of between approximately 120° and 150° with the first elongated hole section 82. The driving pin 70 comes to rest in this third elongated hole section 86 when the hook bolt 30 approaches its engaged position. To be precise, due to the angulation of the third elongated hole section 86 relative to the first elongated hole section 82, the hook bolt 30 is pivoted a small distance back towards its disengaged position when the drive rod 14 is moved fully into its engaged position and thus the driving pin 70 is guided along the third elongated hole section 86 to its end.
[0053] In this position, the hook bolt 30 itself cannot be forcibly pivoted back into its disengaged position, since this would require the driver pin 70 to first be pushed back into the first elongated hole section 82, which, however, is not possible by simply pivoting the hook bolt 30 toward its disengaged position. The hook bolt 30 is thus secured in its engaged position due to the angling of the third elongated hole section 86, so that it cannot be forcibly pivoted back into its disengaged position, for example, in the event of a break-in attempt.
