Description

Technical Field

[0001] The invention relates to a mounting attachment for locking a movable leaf, for example a leaf of a lift-and-slide door or a lift-and-slide window. Background Art

[0002] In order to be able to lock such movable leaves, for example leaves of lift-sliding doors or lift-sliding windows, in their closed position on the frame, a latch lock is usually mounted on the frame, which latch lock engages with a drive rod of the mounting attachment of the leaf in the locked position of the leaf. Specifically, for this purpose, an elongated opening is formed in the drive rod of the mounting attachment, which opening has a first slit-shaped or elongated opening section of a first width and a second opening section of a second width, the second width being greater than the first width. When the leaf is closed, the latch lock first enters the slightly wider second opening section, and then when the leaf is lowered, the latch lock enters the first slit-shaped or elongated opening section, which then engages with its edge behind the latch head of the latch lock, thereby fixing the leaf on the frame. Similarly, an elongated opening partially aligned with the opening of the drive rod is formed in the cover plate, along which the drive rod is guided translationally movable between its locked position and its unlocked position. The slotted opening in the cover plate in question allows the wing to be lowered when the latch on the frame projects through the slotted opening in the cover plate into the opening of the transmission rod in the closed position of the sliding wing.

[0003] Other mounting attachments for locking the sliding wing to the frame have also appeared recently, in which no latch lock is mounted on the frame. Instead, for example, a corresponding latch element, such as a hook lock or a latch lock, can be provided on the wing itself, which latch element can engage with a locking element provided on the frame in the closed position of the wing, thereby fixing the sliding wing to the frame.

[0004] However, in order to be able to arrange such a latching element on a wing element, a specially designed assembly accessory has been required so far, which is specifically designed for attaching the corresponding latching element to the sliding wing. Therefore, different assembly accessories must be manufactured and stored (stocked) according to the type of latching element or the corresponding latching element. Summary of the invention

[0005] The object of the invention is to propose a mounting accessory for locking a movable wing which can be used regardless of the type of locking, such as a latch lock on the frame, a hook lock on the wing or a latch lock on the wing.

[0006] The object of the present invention is achieved by an assembly accessory having the features described in claim 1, and in particular by the following manner: the assembly accessory includes a latching element, which is effectively driven and connected to the transmission rod via a connecting element, and the latching element, at least in the locked position, not only extends through the opening of the transmission rod, in particular its first opening portion, but also extends through the long hole opening of the face cover.

[0007] That is, according to the present invention, it can be said that the conventional assembly attachment is improved by using a latching element, which can be engaged with a locking member arranged on the frame in the closed position of the sliding leaf, and for this purpose, the latching element not only extends through the opening of the transmission rod, but also extends through the long hole opening of the cover plate. As for the conventional assembly attachment mentioned here, it is characterized by a cover plate and a transmission rod that is guided thereon in a translationally movable manner between a locking position and an unlocking position, and an opening is constructed in the transmission rod that is at least partially aligned with the long hole opening of the cover plate, and the opening has: a slit-shaped or elongated first opening portion, which extends perpendicularly to the longitudinal direction of the transmission rod and has a first width; and a second opening portion that transitions to the first opening portion at one end, which has a second width, which is greater than the first width.

[0008] The transmission rod opening mentioned here, through which the latching element extends at least in the locked position, is thus to a certain extent an elongated hole opening with a first width, wherein the elongated hole opening has an enlarged area at one end in the form of a second opening portion with a second width. The second opening portion can be, for example, a circular opening portion with a diameter corresponding to the second width, or also a further elongated hole opening, which is a continuation of the first opening portion or the elongated hole opening with the first width and has the second width.

[0009] Since the latching element of the improved assembly attachment is operatively connected to the transmission rod, the latching element can be adjusted in the closed position of the wing by actuating the transmission rod and thereby engages with a locking member on the frame, thereby fixing the sliding wing on the frame.

[0010] In contrast, for a lifting and sliding wing with a latch lock fixedly mounted on the frame in a conventional manner, the assembly attachment may not be modified with a latch element in the manner of the invention, but rather the latch lock located on the frame can be engaged by the edge of the slit-shaped first opening portion of the opening of the transmission rod to lock the lifting and sliding wing on the frame. Thus, the same assembly attachment can be used depending on the type of locking, eliminating the need to manufacture and stock different assembly attachments.

[0011] Preferred embodiments of the invention will be discussed in the following, further embodiments will result from the dependent claims, the description of the figures and the figures themselves.

[0012] According to one embodiment, the latching element can be constructed as a hook or a hook lock, which can be pivoted about an axis between a disengaged position corresponding to the unlocking position of the transmission rod and an engaged position corresponding to the locking position of the transmission rod, for which purpose the coupling element has a rack portion that meshes with a gear portion provided on the hook lock. That is, the hook lock is operatively drivenly connected to the transmission rod via a rack transmission. In other words, in order to enable the hook lock to pivot between its engaged position (Ineingriffsstellung) and its disengaged position (Auβereingriffsstellung), it is now no longer necessary to form a rack portion or a toothed portion of the hook lock on the existing assembly accessory or its transmission rod that meshes with the gear portion of the hook lock in order to be able to adjust the hook lock. The assembly accessory itself can remain unchanged because the rack portion is formed on the coupling element that is connected to the known assembly accessory or its transmission rod.

[0013] According to another embodiment, the rack can extend parallel to the transmission rod, wherein the axis around which the hook lock can be pivoted is located between the transmission rod and the rack. Therefore, when viewed from the transmission rod, the hook is to some extent engaged by the rack.

[0014] If the hook has a substantially U-shaped shape with an articulated end in which the axis is located and an opposite free end, then due to the fact that the hook lock is to some extent engaged by the toothed rack in the above-described manner, the free end of the hook lock has a movement component when reaching the engaged position, which movement component is directed opposite to the movement direction of the transmission rod when reaching the locked position. In other words, if the transmission rod moves downward from its unlocked position in the direction of its locked position, the free end of the hook lock has a movement component directed upward when reaching its engaged position. Therefore, the U-shaped hook lock is to some extent oriented so that the "U" formed by the hook lock opens upward in the engaged position, or the opening of the "U" is located at the top in the engaged position.

[0015] Since the rack part of the coupling element is spaced apart from the transmission rod according to the aforementioned embodiment, according to another embodiment, the coupling element can have a coupling part that spans the interval between the transmission rod and the rack part and has a free end connected to the transmission rod. Thus, the coupling element can be a substantially L-shaped component, wherein the two sides of the "L" are formed by the rack part on the one hand and by the coupling part on the other hand.

[0016] In order to make the assembly accessories handleable as a unit, instead of having to install, for example, a latch element as a separate component in the assembly groove, according to another embodiment, the hook lock and the coupling element can be arranged between two side walls fastened to the cover plate, wherein the hook lock is pivotally mounted on the side wall about an axis, and the coupling element is movably mounted on the side wall along the longitudinal extension direction of the rack part. For example, a guide groove (Führungsnut) can be formed in each side wall, and a corresponding guide part of the rack part is engaged in the guide groove, so that the rack part can be movably guided in the side wall.

[0017] According to another embodiment, the toothed rack can have an idle travel or a certain amount of play relative to the hook lock in the engaged position of the hook lock, which allows the toothed rack to be adjusted with play between a first and a second idle travel position. In particular, it can be provided that the teeth formed on the hook lock engage with play in the associated recesses or corresponding tooth gaps of the toothed rack in the engaged position of the hook lock, the play being so great that in the first idle travel position, other teeth of the gear part can mesh with the teeth of the toothed rack, whereas in the second idle travel position, meshing of the other teeth of the gear part with the teeth of the toothed rack is prevented.

[0018] Thus, in the second idle travel position, the top surfaces of the teeth of the gear part touch the top surfaces of the teeth of the rack part, thereby preventing the transmission or rack drive. Therefore, if the flap is lifted, for example, in the event of an attempted burglary, the hook lock can be pivoted from its engaged position to its disengaged position, which in turn is prevented in the above-described manner because the rack drive is prevented. Only when the rack part is transferred from its second idle travel position to its first idle travel position by actuating the transmission lever against the force of gravity, the teeth of the gear part of the hook lock mesh with the teeth of the rack part, so that when the transmission lever is further actuated, the hook part can be rotated in the desired manner into its disengaged position.

[0019] In contrast to the aforementioned embodiment in which the latching element is constructed as a hook lock, according to another embodiment, the latching element can be constructed as a mushroom head pin, which is fixedly installed in the opening of the transmission rod and remains there, more precisely regardless of whether the transmission rod is in its locked position or unlocked position.

[0020] In order to install the mushroom pin in the opening of the transmission rod, according to another embodiment, a filler piece can be used as a coupling element, which carries the mushroom pin and is fitted into the opening of the transmission rod in a form-fitting manner. Thus, by installing the filler piece with the mushroom pin arranged thereon in the opening of the transmission rod, the assembly attachment can be improved very easily.

[0021] According to another embodiment, the filler piece can be fixed in the opening of the transmission rod by the mushroom pin itself, for which purpose the mushroom pin has a seat spaced apart from its mushroom head at the end, which is tensioned relative to the edge of the first slit-shaped or elongated opening of the transmission rod by a screwing element such as a nut (which is screwed onto the end of the mushroom pin opposite the mushroom head). The mushroom pin thus acts as a screw, by means of which the filler piece is screwed together with the mushroom pin arranged therein into the first slit-shaped opening.

[0022] In contrast to the above-described embodiment in which the hook lock is operatively coupled to the drive rod via a rack drive, according to another embodiment, a coupling element connected to the drive rod can be operatively coupled to the hook lock via a follower pin. In other words, the coupling element and the hook lock are articulated to each other via the follower pin. The movement of the coupling element is thus transmitted to the hook lock via the follower pin, so that when the drive rod moves between its unlocked position and its locked position, the hook lock pivots via the follower pin between its disengaged position and its engaged position.

[0023] In particular, it can be provided that the follower pin extends through a first slotted opening in the coupling element, which is oriented perpendicularly to the direction of movement of the drive rod, and a second slotted opening in the hook lock, the second slotted opening being oriented such that the axis of the hook lock is located in the continuation of the longitudinal extension of the second slotted opening. The follower pin can thus be moved in translation both relative to the coupling element and the hook lock, so that when the drive rod and thus the coupling element moves, no jamming occurs between the hook lock and the coupling element, as desired.

[0024] According to another embodiment, it can be provided that in at least one side wall, but preferably in both side walls between which the hook lock and the coupling element are located, a guide slot is formed, which movably accommodates the follower pin and which preferably comprises a first slot section parallel to the direction of movement of the transmission rod. Thus, a forced guide is formed by the guide slot, by which the follower pin is forcedly guided between a position corresponding to the engaged position of the hook lock and a position corresponding to the disengaged position of the hook lock when the transmission rod and the coupling element are adjusted between the unlocked position and the locked position.

[0025] According to a further embodiment, it can be provided that the first slotted hole section transitions at a first end into a second slotted hole section, which encloses an angle of about 120° to 150° with the first slotted hole section and in which the follower pin is located when the hook lock is in its disengaged position. Additionally or alternatively to this, the first slotted hole section can transition at a second end into a third slotted hole section, which encloses an angle of about 120° to 150° with the first slotted hole section and in which the follower pin is located when the hook lock is in its engaged position. In this embodiment, preferably, the ends of the second and / or third slotted hole section are further away from the transmission rod than the first slotted hole section. Due to the angle of the second slotted hole section relative to the first slotted hole section, only one movement component of the movement of the follower pin is transmitted to the hook lock, whereby the rotation speed of the hook lock slows down when the hook lock approaches its disengaged position, while the transmission rod speed or the coupling element speed remains constant.

[0026] If, on the other hand, the hook lock has reached its engaged position, when the transmission lever has been fully moved into its unlocked position, the hook lock will be pivoted back minimally in the direction of its disengaged position due to the angle of the third slotted hole section relative to the first slotted hole section. In this position, the hook lock cannot be pivoted directly back into its disengaged position, for example, even under violent action during an attempted burglary. To this end, the follower pin must first be pushed back into the first slotted hole section. Due to the angle of the third slotted hole section relative to the first slotted hole section, the transmission device is blocked so that the hook lock itself cannot be forcibly pivoted directly back into its disengaged position.

[0034] First refer to Figure 1a , 2a , 3a and 4a describe a conventional assembly attachment 10, which can be equipped with additional latching elements 30, 60 according to the manner and method of the invention when necessary. The assembly attachment 10 has a cover plate 12, by which the assembly attachment 10 is installed in an assembly groove of a sliding wing (for example, a lifting sliding wing (not shown)), and the assembly groove is covered by the cover plate in the assembled state of the assembly attachment 10. In addition, the assembly attachment 10 has a transmission rod 14, which is movably guided along the cover plate 12, more precisely, between a locked position and an unlocked position.

[0035] Especially from Figure 2a As can be seen in the figure, a plurality of slotted openings are constructed in the transmission rod 14, wherein the slotted opening indicated here by the reference numeral "16" comprises an elongated or slit-shaped first opening portion 16a and a second opening portion 16b, the first opening portion 16a transitioning to the second opening portion at one end, and the second opening portion having a greater width than the first opening portion 16a. Therefore, the slotted opening 16 is to some extent a slotted hole having an elongated widening at its lower end. In other words, the slotted opening 16 is to some extent two slots of different widths, which transition into each other.

[0036] Furthermore, a coupling opening 18 is also formed in the transmission rod 14, the purpose or function of which will be discussed in more detail below. Figure 1a As can be seen, a long hole opening 20 is also formed in the cover plate 12, wherein the long hole opening 20 is aligned with a portion of the long hole opening 16 of the transmission rod 14 according to the position of the transmission rod 14, which can be seen, for example, Figure 4a ,Depend on Figure 4a It can be seen that in the locking position shown, the elongated hole opening 20 of the cover plate 12 is aligned with the first opening portion 16 a of the elongated hole opening 16 of the transmission rod 14 .

[0037] On the contrary, in the unlocked position of the transmission rod 14, the second opening portion 16b of the long hole opening 16 of the transmission rod 14 is aligned with the long hole opening 20 of the cover plate 12, so that in the unlocked state, when the lifting and sliding wing where the assembly accessory 10 is located is closed, the latch lock 22 fastened to the frame (not shown) can be introduced into the two openings 16b, 20 aligned with each other.

[0038] In this closed state, if the wing is now lowered by the transmission rod 14 from its unlocked position to its locked position, the position of the latch lock 22 inside the elongated hole 20 of the cover plate 12 will also change. Likewise, in the locked position of the transmission rod 14, the first opening 16a of the elongated hole opening 16 of the transmission rod 14 or the two mutually opposite edges of the opening 16a engage the latch head 24 of the latch lock 22, as shown in FIG. Figure 3a As shown. The sliding leaf is thus fixed on the frame in its closed position by the latch head 24 being rearwardly engaged by two mutually opposite edge portions of the opening 16a. In this respect, this corresponds to the known working method of the mounting attachment 10.

[0039] The following will refer to Figure 1b , 2b , 3b, 4b illustrate a first embodiment, in which the aforementioned assembly attachment 10 is retrofitted with a latching element in the form of a hook lock 30. The hook lock 30 is a substantially U-shaped hook element, which is arranged between two side walls 32, which are spaced apart from each other and extend in parallel, and is fastened to the cover plate 12. Here, the hook lock 30 has an end 36 hinged to the two side walls 32 and a free end 34 opposite the hinged end 36. Here, the hook lock 30 can be pivoted in particular about an axis 38 between its engaged position and a disengaged position, the engaged position corresponding to the locked position of the transmission rod 14, and the disengaged position corresponding to the unlocked position of the transmission rod 14. Here, in the engaged position, the hook lock 30 extends through the elongated hole opening 16 of the transmission rod 14, and in particular through the first opening portion 16a of the elongated hole opening 16.

[0040] The coupling element 40 is likewise located between the two side walls 32 and is movably mounted on these side walls parallel to the longitudinal extension of the transmission rod 14. For this purpose, an elongated cutout 56 can be formed in each of the side walls 32, which can movably accommodate a guide 58 formed on the coupling element 40. The guide slot formed in this way is Figure 1b and Figure 2b In Figure 5 This can be seen in the middle diagram of .

[0041] In order to synchronize the movement of the hook lock 30 with the movement of the transmission rod 14 so that the engaged position of the hook lock 30 corresponds to the locked position of the transmission rod 14 and the disengaged position of the hook lock 30 corresponds to the unlocked position of the transmission rod 14, the hook lock 30 is operatively connected to the transmission rod 14 via a coupling element 40 (see in particular Figure 3b ). Thus, the movement of the transmission rod 14 is transmitted to the hook lock 30 via the coupling element 40, which will be described in more detail below.

[0042] The coupling element 40 is a component that has a rack portion 42 extending parallel to the transmission rod 14 and a coupling portion 44 spanning the interval between the transmission rod 14 and the rack portion 42, in which the shaft 38 is located. The coupling portion 44 has a free end 46 that engages in a form-fitting manner in the coupling opening 18 of the transmission rod 14, so that the coupling element 40 is driven by the transmission rod 14. The movement of the coupling element 40 is transmitted to the hook element 30 via its rack portion 42, and for this purpose, a gear portion 48 is provided on the hinged end 36 of the hook element, and the teeth of the gear portion mesh with the teeth of the rack portion 42, see Figure 3b , but in this figure, due to the cut-out method, only one tooth 50 of the gear part 48 can be seen in its entirety. Therefore, the hook lock 30 is operatively connected to the transmission rod 14 via the coupling element 40, and the transmission rod 14 can thus be manipulated to pivot from its disengaged position (in which the free end 34 of the hook lock 30 is approximately located below the axis 38) through the long hole opening 16 of the transmission rod 14 and the long hole opening 20 of the cover plate 12 until the free end 34 of the hook lock 30 engages with the latch 52 of the locking member 54 on the frame (not shown), as shown in FIG. Figure 3b Thus, according to the invention, the existing slotted openings 16 , 20 of the cover plate 12 or the transmission rod 14 are used to accommodate the hook lock 30 in its locked position.

[0043] Since the rack portion 42 engages the gear portion 38 of the hook lock 30 to engage therewith to a certain extent after the transmission rod 14, the free end 34 of the hook lock 30 has an upward movement component when reaching the engaged position of the hook lock 30, while the transmission rod 14 moves downward in the direction of its locked position. Therefore, a movement reversal between the movement direction of the transmission rod 14 and the free end 34 of the hook lock 30 is achieved to a certain extent, which is why in the embodiment proposed here, the generally U-shaped hook lock 30 is oriented so that the opening of the "U" is located at the top in the engaged position.

[0044] In order to prevent the hook lock 30 from being forcibly pivoted from its engaged position to its disengaged position when the lifting and sliding wing equipped with the assembly attachment 10 is forcibly lifted, the assembly attachment 10 has a self-locking function, which will prevent the assembly attachment 10 and thus prevent the hook lock 30 from pivoting from its engaged position to its disengaged position due to the lifting of the lifting and sliding wing.

[0045] In order to realize the self-locking function, the rack part 42 has an idle stroke or a certain clearance relative to the hook lock 30 in the engagement position of the hook lock 30, which allows the rack part 42 to be adjusted with clearance between the first and second idle stroke positions, into which the rack part 42 will squeeze due to gravity. For this purpose, it is particularly provided that the last tooth 50 of the gear part 48 engages with clearance in the recess or tooth gap 51 of the rack part 42 in the engagement position of the hook lock 30, wherein the clearance is so large that in the first idle stroke position, the other teeth of the gear part 48 can mesh with the teeth of the rack part 42, and in the second idle stroke position, the meshing of the other teeth of the gear part 48 with the teeth of the rack part 42 is prevented.

[0046] The teeth 50 can be accommodated with clearance in the corresponding recesses or tooth gaps 51 by making the dimension of the tooth gaps 51 in the longitudinal direction of the rack part 42 approximately twice the dimension of the teeth 50 measured in the longitudinal direction of the rack part 42. Figure 3b When the rack portion 48 is in its second idle stroke position (to which the rack portion is pressed by gravity), the top surface of the next tooth 53 will hit the top surface of the tooth of the rack portion 42, thereby preventing the hook lock 30 from forcibly pivoting.

[0047] Only when the transmission rod 14 is slightly lifted from its locking position and the rack part 42 is thus also slightly lifted from its second idle stroke position according to Figure 3, overcoming the gravity, the self-locking function of the assembly attachment 10 is canceled, because in the first idle stroke position of the rack part 42, the tooth 53 no longer hits the top surface of the tooth of the rack part 42, but enters the next tooth gap.

[0048] Refer to the following Figure 1c , 2c , 3c and 4c describe a second embodiment, in which, according to Figure 1a , 2a , 3a and 4a has been modified by a latching element in the form of a mushroom pin 60, which in the locked position in the transmission rod 14 extends through the elongated hole opening 16 of the transmission rod 14 and the elongated hole opening 20 of the cover plate 12. Here, the mushroom pin 60 is carried by a filler piece 62 serving as a coupling element, through which the mushroom pin 60 extends, see Figure 3c as well as Figure 5 .

[0049] Especially from Figure 5 As can be seen from the right side of the drawing, the filler 62 has a profile on its front side, which substantially corresponds to the edge of the long hole opening 16 or the edges of the two openings 16a, 16b of the transmission rod 14. Therefore, the filler 62 can be assembled into the long hole opening 16 of the transmission rod 14 in a form-fitting manner and fixed therein. For this purpose, the mushroom head pin 60 has a flange-shaped support portion 66 spaced apart from its mushroom head 64, and the support portion is in contact with the edge of the first opening portion 16a of the long hole opening 16 of the transmission rod 14, as shown in FIG. Figure 2c On the other hand, a nut 68 is screwed onto the end of the mushroom head pin 60 opposite to the mushroom head 64, and the support portion 66 is clamped on the opposite edges of the first opening portion 16a by means of the nut.

[0050] The mushroom pin 60 can thus be transferred by the transmission rod 14 from its disengaged position to its engaged position, in which the mushroom pin engages behind the locking portion of the closure element arranged on the frame.

[0051] Refer to the following Figure 6 , Figure 7 and Figure 8 An embodiment is described in which the hook lock 30 is not as Figure 1b , 2b , 3b, 4b, the transmission is not through the rack, but through the follower pin 70 and the connecting transmission rod (only in Figure 6 The hook lock 30 is effectively driven to be connected with a coupling element 40 (schematically shown in FIG. 1 ). In this embodiment, the hook lock 30 is also a roughly U-shaped hook element, which is arranged between two side walls 32, which are spaced apart from each other and extend in parallel, and is fastened or can be fastened to a face cover (not shown). The hook lock 30 here has an end 36 hinged on the two side walls 32 and a free end 34 opposite to the hinged end 36. Therefore, the hook lock 30 can pivot around the axis 38 between its engaged position and disengaged position, the engaged position corresponding to the locked position of the transmission rod 14, and the disengaged position corresponding to the unlocked position of the transmission rod. As shown Figure 1b , 2b , 3b and 4b, where the hook lock 30 extends through the long hole opening 16 of the transmission rod 14, and in particular extends through the first opening portion 16a of the long hole opening 16 when the hook lock 30 is in the engaged position.

[0052] The hook lock 30 is flanked on both sides by the coupling elements 40. In other words, the two coupling elements 40 are located between the hook lock 30 and the respective side wall 32. The coupling elements 40 are designed essentially identically, so that only the embodiment of one of the two coupling elements 40 will be discussed below. The same applies to the side wall 32.

[0053] The coupling element 40 is movably guided on the corresponding side wall 32 parallel to the longitudinal extension of the transmission rod 14, for which purpose an elongated cutout 72 is formed in the coupling element 40, through which the axis 38 extends, about which the hook lock 30 is pivotably mounted on the side wall 32. In addition, in order to achieve an effective driving connection of the coupling element 40 with the transmission rod 14, a nose 74 is formed on the coupling element 40, which nose is received in the transmission rod 14 in a form-fitting manner via a corresponding cutout 88. The coupling element 40 is thus connected to the transmission rod 14 in a form-fitting manner and is guided parallel to the transmission rod 14 via the axis 38 extending through the cutout 72 formed in the coupling element 40.

[0054] In order to synchronize the movement of the hook lock 30 with the movement of the transmission rod 14 so that the engaged position of the hook lock 30 corresponds to the locked position of the transmission rod 14 and the disengaged position of the hook lock 30 corresponds to the unlocked position of the transmission rod 14, the hook lock 30 is operatively drivingly coupled to the coupling element 40 connected to the transmission rod 14 via the follower pin 70. Figure 6 , Figure 7 and Figure 8 In the embodiment specifically shown, the follower pin 70 extends through a first slot opening 76 in the coupling element 40, perpendicular to the direction of movement of the transmission rod 14, and a second slot opening 78 in the hook lock 30. The second slot opening 78 is oriented in such a way that the axis 38 of the hook lock 30 is located in the continuation of the longitudinal extension of the second slot opening 78. The follower pin 30 can therefore be moved in a translational manner not only relative to the coupling element 40 but also relative to the hook lock 30, so that when the transmission rod 14 and thus the coupling element 40 are moved, no jamming occurs between the hook lock 30 and the coupling element 40. For example, if the coupling element 40 is moved from Figure 7 The unlocked position shown begins to move downwards, and the follower pin 70 can slide in the slotted opening 78 of the hook lock 30 in the direction of the axis 38 , since otherwise a pivoting movement of the hook lock 30 would be prevented.

[0055] In addition, Figure 6 As shown, a guide notch 80 is formed in the front side wall 32, wherein a corresponding guide notch can be formed in the rear side wall 32. The guide notches 80 formed in both side walls 32 accommodate the ends of the follower pin 70 movably. Thus, a forced guide is formed by the guide notches 80, by which the follower pin 70 is moved between a position corresponding to the engaged position of the hook lock 30 and a position corresponding to the disengaged position of the hook lock 30 (e.g., in the case of the locking position) when the transmission rod 14 and the coupling element 40 via the transmission rod are adjusted between the unlocked position and the locked position. Figure 6 , Figure 7 and Figure 8 shown) are forced to be guided between.

[0056] Specifically, in the embodiment shown here, the guide slot 80 has a first slot section 82 which is parallel to the movement direction of the transmission rod 14. The follower pin 70 is guided in this first slot section 82 over the majority of the pivoting movement of the hook lock 30 between its engaged position and its disengaged position.

[0057] The first slot section 82 transitions at its upper end into the second slot section 84, with which the first slot section 82 encloses an angle of between about 120° and 150°. The angle mentioned here is selected such that when the hook lock 30 is in its position according to Figure 6 , Figure 7 and Figure 8 In the disengaged position, the longitudinal extension of the second slotted hole section 84 coincides with the longitudinal extension of the slotted hole opening 78 of the hook lock 30. Therefore, shortly before the unlocking position of the transmission rod 14 is reached, the follower pin 70 reaches the second slotted hole section 84, which results in that only one movement component of the movement of the follower pin 70 is transmitted to the hook lock 30, whereby, while the transmission rod speed or the coupling element speed remains constant, the rotation speed of the hook lock 30 slows down when the hook lock 30 approaches its disengaged position.

[0058] The first slotted hole section 82 of the guide slot 80 also transitions at its lower end into a (third) slotted hole section 86, which likewise encloses an angle of between approximately 120° and 150° with the first slotted hole section 82. When the hook lock 30 approaches its engaged position, the follower pin 70 is located in this third slotted hole section 86. More specifically, when the transmission lever 14 has been moved completely into its engaged position and the follower pin 70 has thus been guided along the third slotted hole section 86 to its end, the hook lock 30 is pivoted back a short distance in the direction of its disengaged position due to the angle of the third slotted hole section 86 relative to the first slotted hole section 82.

[0059] Because pure pivoting movement of the hook latch 30 in its disengaging direction is not possible, the hook latch 30 is therefore fixed in its engaged position due to the deflection of the third elongated portion 86, so that it cannot be forcibly pivoted back to its non-engaged position in the event of a burglary attempt, for example.

[0060] In this position, the hook lock 30 itself cannot be forcibly pivoted back directly into its disengaged position, because for this purpose the follower pin 70 must first be pushed back into the first slot section 82, which, however, is not possible by a pure pivoting movement of the hook lock 30 in the direction of its disengaged position. The hook lock 30 is therefore fixed in its engaged position due to the angling of the third slot section 86, so that the hook lock cannot be forcibly pivoted back into its disengaged position in the event of a burglary, for example.
