Summary of the invention

The invention is based on the object of developing the lock of the generic type in an advantageous manner and, in particular, of increasing the locking security of the lock.

The object is achieved by the invention specified in the claims, the subclaims not only describing advantageous developments of each of the independent claims, but also being independent solutions to the problem.

According to a first aspect of the invention, it is proposed that the lock, which is in particular a secondary lock, that is, can be driven by a main lock that can move a drive rod with which a drive slide of the secondary lock is displaced, has two hook bolts. Each of the two hook bolts has a blocking flank. In the pre-locked locking position, the two blocking flanks face each other. A blocking element according to the invention is designed in such a way that its blocking flanks are opposite the blocking flanks. The two hook latches can be pivoted back from the pre-closed position into the closed position. The two blocking flanks of the hook bolt move along a movement path. If the blocking element assumes its blocking position, the blocking flanks lie in the movement path of the two blocking flanks, so that the hook latches are blocked from improper displacement from the pre-closed position into the closed position. The locking element can be an elongated body, which forms the locking flanks at two opposite ends. An axis of rotation about which the blocking element can be pivoted from a non-blocking position into a blocking position can be arranged between the two blocking flanks. This is preferably done by a pivot angle of 70 ° to 110 ° or 80 ° to 100 °, in particular about 90 °, so that the locking element is in the non-blocking position transversely to a direction of displacement of the drive slide. In the blocking position, the blocking element is preferably in a position parallel to the direction of displacement of the drive slide. The locking element can have control sections. These control sections interact with control edges. The control flanks can be formed by the drive slide. The locking element can preferably be displaced between its end positions in a cam-controlled manner. It is provided in particular that two drive slides arranged parallel to one another and, in particular, of identical design are provided, one of which is displaced along the lock cover and the other along the lock base. The hook bolts can thus extend between the two drive slides. The locking element is also preferably located between the two drive slides. At least one of the two drive slides, preferably both drive slides, form a control window which forms the control flanks that engage the control sections of the locking element in order to pivot the locking element. It is provided in particular that the blocking element has two control sections pointing away from one another, which in the blocking position of the blocking element lie between two mutually pointing control edges of the control window. The blocking element is preferably tied up in the blocking position by the drive slide. It can also be provided that the locking element is displaced from the blocking position when the drive slide is displaced back by a control section running up against a control flank. It is provided in particular that the drive slide overcomes a clearance. To do this, the drive slide performs an idle stroke without the hook bolt being dragged along with it become. During this idle stroke, the locking element comes out of its locked blocking position and is pivoted at least slightly out of the blocking position. For this purpose, a control section of the locking element slides along a control flank of the drive slide.

According to a second aspect of the invention, which can be combined with the features of the first aspect, it is proposed that between a first end position in which a first end stop of the drive slide rests against a first end stop fixed to the housing or a second end position in which a second end stop of the Drive slide rests against a second stop fixed to the housing, and the position in which a first or second drive shoulder engages a first or second drive shoulder assigned to it, an idle stroke of the drive slide is provided. During this idle stroke, a locking element can be unlocked, with which a backward displacement of one or more hook bolts from the pre-closed position into the closed position is blocked. In particular, it is provided that the first or second output shoulder is formed by a tooth. The tooth is in particular assigned to an output toothing that is preferably firmly seated on the hook bolt. The first or second drive shoulder can be formed by a tooth flank of a drive toothing. The drive toothing can have teeth and tooth gaps. A driven tooth can engage in the tooth gaps. In particular, it is provided that in an end position of the drive slide a first stop of the drive slide rests against a first end stop of the housing or a second stop of the drive slide rests against a second end stop of the housing. From this end position, the drive slide is displaced linearly, in particular in a downward movement. The idle stroke is overcome. In the final phase of overcoming the idle stroke, the drive shoulder comes against an output shoulder, which is formed by an essentially transverse tooth of the output toothing. During this shift can a driven tooth emerge from a tooth gap of the drive slide, in which the tooth is otherwise held in a rotation-inhibiting manner. The two tooth flanks of the tooth gap of the drive slide can run parallel to one another and in the direction of displacement of the drive slide.

According to a third aspect of the invention, which can be combined with the features of the two aspects described above, it is proposed that the hook bolt has an output toothing with output teeth which mesh with a drive toothing of the drive slide which has at least one drive tooth and a drive tooth gap. According to the invention, the output toothing should form at least one long output tooth and one short output tooth that is shorter in the radial direction in relation to the axis of rotation of the output toothing. The short output tooth can have a blunt tooth tip. The long output tooth can have a pointed tooth tip. A, for example, curved tip flank can adjoin the tip of the pointed tooth tip. According to the invention, this tip flank should rest against a blunt, for example straight, tooth tip of the drive toothing in the pre-closed position. During an idle stroke of the drive slide, the tip flank of the long output tooth can slide along the drive tooth head of the drive tooth. When the drive slide is shifted either from the closed position into the closed position or vice versa, the tooth of the output toothing resting on the tooth tip of the output tooth can enter a tooth gap of the drive toothing. If the drive slide is displaced further, this has the consequence that the output toothing is rotated. The at least one hook bolt is then shifted either from the closed position into the closed position or from the closed position into the closed position.

According to a fourth aspect of the invention, which can be combined with the features of the aspects described above, it is proposed that the masses of the hook bolts and the drive slide engaging them are balanced so that the hook bars are balanced by the dead weight of the drive slide engaging them or other connecting rods that engage the drive slide are held in the pre-locked position. For this purpose, it is proposed in particular that the hook bolt has a rear section which lies opposite the hook section of the hook bolt in relation to the axis of rotation of the hook bolt. This rear section preferably forms a blocking flank which can interact with a blocking element. To move the at least one hook bolt from the closed position to the pre-closed position, the drive slide is preferably moved in a downward direction. The drive slide has a drive toothing, each of the two hook bolts being assigned a drive toothing assigned to it. The two drive gears can engage the respective output gears of the hook latch on different sides. It is provided in particular that the hook sections of the hook bolts move towards one another when they are shifted into the pre-locked position. While a rear section of the hook bolt can have material recesses which reduce the mass of the rear section, it can be provided that a section of the hook bolt forming the hook section has an additional mass accumulation.

According to a fifth aspect of the invention, which can be combined with the features of the aspects described above, it is proposed that the hook bolts have bearing bores in which circular cylindrical sections of bearing journals are preferably inserted. With the bearing pin, the two hook bolts are mounted on a lock cover or a lock bottom. End sections of the bearing pin engage in bearing openings in the lock base or the castle cover. It is provided that the two end sections have straight sections. The end sections can otherwise have the same diameter as the circular cylindrical sections, so that a step is formed in the transition area between the circular cylindrical sections and the end sections. These straight sections form contact surfaces. The contact surfaces run transversely to the direction of extension of a faceplate or to the direction of displacement of a drive slide. The contact surfaces form force transmission surfaces. These force transmission surfaces lie flat on force receiving surfaces. The latter are formed by the bearing openings. It is provided in particular that the force transmission surfaces or the force receiving surfaces are arranged on the sides of the end sections or the bearing openings which are directed away from the hook openings. If a force directed in the closing direction is applied to the hook sections, this force can be diverted into the lock case via the flat contact surfaces. In cross section, the profile of the end section, which corresponds to the profile of the bearing opening, has a circular outline which is cut by a straight line so that the contact surfaces extend on a secant. No notch-producing forces then develop. The step between the circular cylindrical section supporting the hook bolt and the end section forms a support step on which the lock cover or the lock bottom can be supported.

According to a sixth aspect of the invention, which can be combined with the features of the aspects described above, it is proposed that the two hook bolts, which are driven by the same drive slide and which are arranged in a common lock case and in particular by a common element, in particular a locking element can be blocked against locking back, are so far apart from each other that the associated bolt entry openings of a strike plate are so far apart that in the space between the bolt entry openings a screw-on opening can be provided with which the strike plate can also be fastened to a door frame or to a further door leaf. The two hook bolts can each have rear sections that lie back to back in the closed position inside the lock case. Between these rear sections there can be an element, in particular a blocking element, which can assume a blocking position in the pre-locked locking position. In the closed position, edge sections of the rear sections of the hook bars can engage in niches of the element, in particular the locking element. The element can have a Z-shaped or S-shaped cross section there. Two overlapping niches are formed into each of which an edge section of the hook bolt can dip. The element, in particular the blocking element, can be a rotary element.

Description of the embodiments

The lock shown in the drawings is an additional lock, which is connected to a main lock, not shown in the drawings, as it is, for example, in FIG DE 43 23 725 A1 is described, can work together. The main lock has connecting rods which, when the lock is actuated, can be shifted to the rear of a faceplate 5 in the upward direction or in the downward direction. The lock according to the invention sits on the same faceplate 5 on which the main lock sits and is coupled to a drive rod 40. The drive rod 40 has at least one opening into which at least one driving projection of at least one drive slide 2 engages.

The lock according to the invention has a lock case 1 which has a lock cover 43 on both of its broad sides. On the inside of the lock cover 43 each a flat drive slide 2 is guided, which of the drive rod 40 from one to the Figures 1 and 1a operating position shown, in which a stop 38 of the drive slide 2 rests against an end stop 18 of the lock case 1, in a in the Figures 6, 6a The operating position shown, in which a stop 37 of the drive slide 2 rests against an end stop 19 of the lock case 1, can be displaced. During this shift, two hook bolts 3, 4 rotatably mounted within the lock case 1 are removed from the in the Figure 1 in the inferred position shown in the Figure 6 Relocated locked position shown. The two hook bars 3, 4 rotate in opposite directions so that the two hook sections 3 ', 4' of the hook bars 3 move towards one another. In the pre-locked state of the two hook bolts 3, 4, hook openings 3 ", 4" pointing away from one another are formed. When the bolt is advanced, the hook sections 3 ′, 4 ′ pass through bolt passage openings 12 of the faceplate 5.

The Figure 12 shows an operating position according to Figure 6 , in which the two hook bolts 3, 4 are fully extended. During the rotational movement of the hook bolts 3, 4, the hook sections 3 ′ and 4 ′ move through bolt entry openings 51 of a strike plate 50. The hook sections 3 ', 4' engage behind the strike plate 50 and engage in recesses 54 of a door frame or the like to which the strike plate 50 is attached. The distance between the two rear sides 3 ''',4''' of the two hook openings 3 '', 4 '' facing each other in the pre-closed state is dimensioned so large that the section of the striking plate 50 lying between them, i.e. the section of the strike plate between the two bolt entry openings 51 is sufficiently large to provide a screw-on opening 52 through which a fastening screw 53 can reach. In particular, it is provided that the distance between the free ends of the hook sections 3 ', 4' is dimensioned to be sufficiently large that the recesses 54 for the entry of the hook sections 3 ', 4' are sufficiently far apart from one another.

The Figures 11, 12 and 13th show the mounting of the hook bolts 3, 4. The hook bolts 3, 4 each have a bearing bore 41 in which a bearing pin 42 is inserted. The bearing pin 42 has a circular cylindrical section about which the hook bolt 3, 4 can be rotated. The bearing pin 42 has two end sections 44 which engage in openings in the lock cover 43. The end sections 44 form a step, the bottom surface of which rests against an inner side of the lock cover 43. The end section 44 has a rectilinear section 46 which runs like a secant through the circular cross-sectional area of the bearing journal 42. The section 47 forms a force transmission surface which adjoins the bottom surface of the step substantially at right angles. The force transmission surface 46 lies flat against a straight section of the opening in the lock cover 43. The straight section forms a force-absorbing surface 47. The force-absorbing surfaces 47 of the two bearing journals 42 are directed away from one another. If an expanding force is exerted on the two latches 3, 4 in the event of a violent attempt to open them, this force can be diverted into the flat force-absorbing surface 47. A flat force transmission surface 46 lies flat against the flat force absorption surface 47.

The Figures 14a to 15b show the two hook latches 3, 4 in different perspective representations. The hook latches 3, 4 are preferably made of metal and in particular they are zinc die-cast parts. You own on Their broad side faces facing away from each other recesses 55, 56. The recess 55 arranged in the rear area of the hook bolt 3, 4 has a larger volume than the recess 56 arranged in the hook portion. The hook bolt 3, 4 has a toothing on both broad sides. The toothing consists of two essentially identical groups of individual teeth, each group consisting of three teeth 13, 13 '. The Figure 1a shows that the three teeth of the group of teeth are designed differently. The two outer teeth 13 of the group of teeth are shorter teeth. They have a blunt tooth tip 20. A tooth 13 'arranged between the teeth 13 has a greater radial length than the two teeth 13. The middle tooth 13' is accordingly a long tooth. It has a tip 21 with an adjoining tip flank 21 '.

The rear sections of the hook bars 3, 4 have blocking flanks 6, 7. The function of the blocking flanks 6, 7 is in the Figure 7 shown. In the pre-locked locking position, the two blocking flanks 6, 7 face one another. In relation to the axis of rotation of the hook bolt 3, 4, they lie essentially diametrically opposite the hook section 3 ', 4'. The two blocking flanks 6, 7 take in the Figure 7 shown pre-locked locking position their greatest distance from each other. A locking element 8 is provided which, in the pre-locked locking position, lies between the two locking flanks 6, 7, so that the hook locks 3, 4 cannot be closed without first shifting the locking element 8 from the locking position into a release position. For this purpose, the locking element 8 has locking flanks 10 pointing away from one another. If a spreading force is exerted on the hook sections 3 ', 4', the two bearing journals 42 are acted upon in a direction away from one another. The force transmission surface 46 is supported on the force receiving surface 47.

That in the Figures 16a to 16d Locking element 8, shown several times in perspective, has a plurality of control sections 25, 30, 33, 35 with which it is about an axis of rotation 9 from that in FIG Figure 7 blocking position shown in the Figures 2, 3 shown release position can be pivoted. While the locking element 8 extends essentially parallel to the faceplate 5 in the blocking position, in the release position it lies essentially transversely to the direction in which the faceplate 5 extends. For pivoting the blocking element 8 between the blocking position and the release position, the drive slide 2 has several control cams / flanks 23 '. , 27, 32, on which the control sections 25, 30, 33, 35 slide substantially one after the other. The control cams 23 ′, 27, 31, 32 are preferably formed by an edge of a window 39 of the drive slide 2. Each drive slide 2 preferably has such a window 39. The control sections 25, 30, 33, 35 of the locking element 8 are preferably formed by projections pointing away from one another, which are arranged radially spaced from a bearing axis 9 of the locking element 8. The locking element 8 has the shape of a two-armed lever, the two lever arms being offset from one another by an angle of 180 ° and each forming the locking flanks 10 at their free ends. It is S or in cross section. Z-shaped.

The locking element 8 also has a niche 26, 26 'on each of its two broad sides. The recess 26 forms a control section 35 which interacts with a control cam 36 of the hook bolt 3. The control sections 25, 30 pointing away from one another also have the function of counter-stops to move the locking element in the in Figure 6 to fix the locking position shown. The counter stops 25, 30 lie between stops 23 'and 31. The stops 23' and 31 are formed by sections of the control cam or by opposing edge sections of the window 39. For this purpose, the window 39 forms a niche 23 into which which the counterstops 25, 30 having lateral projections of the locking element 8 can enter in the pre-locked locking position.

The two drive slides 2 each have teeth with teeth 15 and tooth gaps 17, which interact with the teeth 13, 13 'of the hook bolt 3, 4 to move the hook bolt 3, 4 back and forth between the pre-closed position and the closed position. The drive slide 2 also have locking recesses 22 into which a tooth 13 can enter in the pre-locked locking position. The tooth 15 also has a flat drive tooth head 15 'on which the tip flank 21' of the tooth 13 can rest. Tooth 15 forms a drive shoulder 16 which, in the closed locking position ( Figure 1, Figure 1a ) from an output shoulder 14, which is formed from the tooth 13, is spaced apart by a distance a. The drive slide 2 must therefore first move freely until it acts on the output shoulder 14 with the drive shoulder 16 in order to rotate the hook latches 3, 4. To guide the drive slide 2, an elongated slot 28 is provided through which a guide pin 29 can reach. With a spring element 49, the drive slide 2 is urged into a position corresponding to the pre-closed locking position.

The way the lock works is as follows:
Starting from one in the Figures 1, 1a The closed position shown, in which a tooth 13 of the hook bolt 3 lies in a locking recess 22 'of the drive slide 2, the drive slide 2 is shifted by the clearance a before the drive shoulder 16 comes against the output shoulder 14 by shifting the drive rod 40 downwards. In this case, a control edge 24 of the window 39 approaches the control section 25 of the blocking element 8. During the downward displacement, the tooth 13 emerges from the locking recess 22 '. The drive tooth head 15 'of the drive tooth 15 slides along the tip flank 21' of the tip 21 of the long tooth 13 '.

The Figure 4 shows a subsequent representation after the drive shoulder 16 has acted on the output shoulder 14 of the tooth 13. The long tooth 13 ′ is now in a position in which it can enter the drive tooth gap 17. The control section 25 of the locking element 8 is still at a distance from the control cam 24.

The Figure 5 shows a subsequent representation, the drive slide 2 being displaced further downward until the control section 25 rests against the control cam 24 of the window 39 and the two hook bolts 3, 4 have been pivoted slightly. The output tooth 13 ′ has now entered the drive tooth gap 17.

The Figure 6 shows a subsequent representation in which the drive slide 2 has been moved down to an end position in which a stop 37 rests against an end stop 19. The hook latches 3, 4 were swiveled completely into the pre-locked position. In the final phase of this displacement of the drive slide 2, the output tooth 13 is spaced from a drive shoulder 16. The tip flank 21 'slides on the drive tooth head 15'. While overcoming the clearance a, an output tooth 13 entered the locking recess 22 and the locking element 8 was pivoted into its blocking position. The control section 25 was activated by the control cam 27.

In the in the Figure 6 The end position shown, the projection forming the control sections 25, 30 and the axis of rotation of the locking element 9 lie in the niche 23 of the window 39. The control section 25 and the control section 30 form counter-stops in this position, which abut against stops 23 ', 31 of the window 39 and which tie the locking element 8 in its blocking position.

The Figure 7 shows that the two locking flanks 10 each lie opposite a blocking flank 6, 7 of the hook bolts 3, 4, so that pivoting of the two hook bolts 3, 4 is not possible.

The Figure 8 shows a follow-up to the Figures 6 , 7th after the drive slide 2 is shifted slightly upwards. The tooth 13 emerges from the locking recess 22 and the clearance a is overcome. The output shoulder 14 is now on the drive shoulder 16. The hook bolts 3, 4 have not yet been pivoted. The control section 30 of the locking element 8 slides along a control flank or cam 32 which pivots the locking element 8 slightly so that the locking flanks 10 no longer rest against the blocking flanks 6, 7. The locking element 8 now assumes a functional position in which the hook bolts 3, 4 can be pivoted.

The Figures 9, 10 show that with a further displacement of the drive slide 2, the locking element 8 is acted upon by a control cam 34 of the hook bolt 3, which slides along a control section 33 of the locking element 8 in order to move the locking element 8 further in the direction of its release position.

The Figure 11 shows the sliding of the control cam 36 on the control section 35 of the locking element 8 and the entry of an edge section 36 'of the hook bolt 3 into the niche 26 of the locking element 8 in order to engage the control section 35 there.

A further displacement of the drive slide 2 leads to that in the Figure 1 position shown, wherein after overcoming the clearance, the tooth 13 enters the locking recess 22 '.
