EP0471976A2 - Espagnolette - Google Patents

Abstract

The invention relates to a door lock in the form of a multiple-locking lock, in which the door lock can be unlocked without key actuation from the inside only, whereas both the lock latch and the lock bolt can be released from outside after key actuation only. The door lock is lockable from inside and outside by pulling up the door handle and can also be released again from inside by pushing down the door handle, without a key being necessary for this.

Description

The invention relates to an espagnolette lock with a latch and a bolt which, like the locking elements, can be moved into the unlocking position by pushing up the respective handle and by pushing down the push button located on the inside of the door, with a key-operated locking cylinder.

With espagnolette locks, the different locking elements, such as locking pins and bolts, are brought into the final position by pulling up the lever handle. The locking elements are unlocked by pressing the lever handle down. The latch is separated from the other functions with the Key operated via the locking cylinder. If the locking elements are not brought into the final position by pulling up the lever handle, only the lock latch is actuated by pressing the lever handle down.

The actuation of the locking elements, the bolt and the lock latch of these previously known espagnolette locks is the same on both sides. This has the disadvantage that such door locks when used as external door locks, for. B. as front door locks, can also be opened from the outside by unauthorized persons by pressing down the door handle, if they are not previously locked again by key operation after each opening. This is very disadvantageous because z. B. children, domestic workers, etc. must always have a key to hand to lock the door after each opening, so as to prevent intrusion by unauthorized persons.

From DE-PS 221 685 a door lock of another type with a device for coupling the outer handle with the inner handle permanently connected to the nut is known. The trap is pulled back using a nut by turning the trigger pin. The arbor is split and has square pins that abut each other in the middle of the lock. The outside handle has a round pin that goes through the inside handle. A lever connected to the lock nut is mounted on the square portion of the inside handle so that the latch can usually only be retracted when this handle is turned. By turning the outer handle, on the other hand, only a spring-influenced disc that holds the handle horizontally is rotated. In order to be able to open from the outside, the two pushers must be coupled, which is done by unlocking a plate that is secured by a guard locking device using the associated key and then lifting it. This plate has a recess at the top in which a body is rotatably mounted. A cutout corresponding to the square sections of the trigger mandrel is provided in the body. If the plate is lifted so far with the help of the key that the axis of the body coincides with that of the presser mandrel sections, the body with its cutout encloses the two square sections of the presser mandrel simultaneously. The handle mandrel sections are now coupled together, so that the lock with the help of the outer handle the open position can be brought. If the door is to be open to everyone, for example in a doctor's office, the coupling of the handle mandrel parts can be effected from the inside by means of a suitable device, for example a clamping screw. As long as this screw is in the active position, it can be easily opened from the outside using the handle alone. The previously known door lock thus has the following features:

• a split nut body;
• a split trigger pin;
• a body operable by a key;
• Depending on the position of the slide, the outer handle is coupled or released with the one half of the nut that is permanently connected to the inner handle in a form-fitting manner and has the nut levers that act on the latch.

From DE-PS 36 07 458 a pushrod lock which can be actuated by means of a pusher and which can be closed by means of a key and a nut having an opening for a pusher arbor is known, which has at least one pushrod in via a positive engagement with a coupling element when rotating in the opposite direction to the latch actuation Pushes the closed position, and with a control segment displaceable by key actuation, which decouples the positive drive connection between the nut and the drive rod when the key is turned into the closed position when the drive rod is in the closed position. In this case, there should be an engagement lock between the nut and the coupling element, which after the key is turned in the unlocked position is only lifted in a certain relative position between the nut and the coupling element. The engagement lock is formed by a nose support surface of the lock nut, which cooperates with a nose of the coupling element. The coupling element is a rack pivotably mounted between its ends on a connecting rod connecting piece, which has one end of the nose, to which a counter toothing meshing with a toothed segment of the nut connects, and which otherwise interacts with the control segment via a pin / recess handle, the toothed rack passing through Displacement of the control segment up to the coupling or uncoupling of the tooth engagement can be pivoted through an angle. The pin / recess handle is lifted in the open position of the drive rod, the pin moving into the recess open to the edge of the control segment when the drive rod is displaced in the closed position. The toothed segment of the nut should have two toothed side edges, the nose contact surface cooperating with the control section adjoining one toothed side edge.

DE-PS 33 16 261 relates to a device for increasing the exclusion stroke of a key-operated, single-turn slide bolt in a mortise lock, with a toggle slide which can be moved by the lock bit and a gearwheel which is moved during its displacement and which is in meshing engagement with an extending in the exclusion direction, stationary rack and its resulting rotary movement resulting from this meshing engagement is transmitted due to a slot / pin engagement on the exclusion stroke of the slide bolt. The gear is to be arranged non-rotatably on a rocker with its end forming the slot / pin engagement to the bolt and is guided in a longitudinally movable manner relative to the touring pusher, in that the stationary one Rack is opposite a rack of the touring pusher that meshes with the gear running parallel. The rocker lies in a rear recess in the broad area of the bolt tail. The touring pusher is fork-shaped and overlaps the broad sides of the bolt tail and is guided with a rib in the lock base and carries a tumbler plate that can be controlled with a rear-facing shoulder in front of and behind a housing pin. The gearwheel axis and the rocker pin lie in the dead bolt position on a dead center line extending in the dead bolt direction.

The invention has for its object to design an espagnolette lock of the required type so that it locks from the outside and inside of the door - that is, all bolts are extended - but can only be opened from the outside with a key, what also applies to the additional bolts.

Starting from a drive rod lock of the type required in the preamble of claim 1, this object is achieved by the features set out in claim 1 .

While the espagnolette lock can be locked from the inside by pulling up the lever handle and can be unlocked again by pushing it down, as can be unlocked from the outside by pulling up the lever handle, but cannot be unlocked again by pressing the lever handle down. This is only possible by pressing the key. The same applies to the operation of the lock latch. It can only be moved from the outside by using a key. A key is no longer required to lock the espagnolette lock according to the invention, but only to unlock it.

These functions are brought about by a special square piece, which is divided into two parts and whose respective part can be rotated by itself. Each part is inserted from one and the other side of the espagnolette lock and screwed into the follower nut located in the housing of the espagnolette lock. There is also a slidable slide inserted in the follower which allows the outside handle to be rotated without the follower being moved. If this slide is moved, the outside handle actuates the follower, which in turn actuates the lock latch and the locking elements. The slide can only be moved by key actuation via a type of interchangeable slide.

In addition, a further return part is provided which surrounds the corresponding square and which, by means of spring pressure, erects the door handle again after it has been pressed down.

The invention also enables a simple, compact spatial shape. One, continuously and larger in diameter The square of the handle arbor is located on the inside of the door, while the other, separate handle part is on the outside of the door.

The change-over slide interacts on the one hand with the key or a key bit that can be actuated by the key, and on the other hand acts on a slide to move it into a position in which the two lock nut parts are non-rotatably coupled to one another.

Advantageous embodiments of the invention are described in patent claims 2 to 9 .

In the embodiment according to claim 2 , there is a simple, compact spatial shape. One, square and larger in diameter of the handle mandrel is arranged on the inside of the door, while the other, separate handle part is on the outside of the door.

Claim 2 describes the special lock nut structure. Since the parts are inserted into each other, this nut builds very compact, so that the outer dimensions of the lock do not increase. Compared to conventional multi-point locks of this type, no change in dimensions can be seen from the outside.

In claim 3 , the structure of the slide is explained.

Claim 4 describes the return part, while claim 5 explains a bolt.

In claim 6 , the push rod is explained in more detail.

Claim 7 describes a rod drive and claim 8 describes the locking drive.

A special latch guide can be seen from claim 9 .

In Fig. 1, the reference numeral 1 denotes a lock base with which a cuff 2 is connected. The cuff 2 has openings 3 and 4 for the passage of a latch 5 and a bolt 6.

The reference numeral 7 denotes a locking cylinder, the key channel of which bears the reference numeral 8. A key, not shown, to be inserted into the key channel 8 actuates a locking bit 9, which is able to act against the lower end face 11 of a change-over slide 10 during its rotational movement when it is set in rotation by the key.

The change slide 10 can be seen in detail from FIGS. 16 and 17. This interchangeable slide 10 has an elongated hole 12 approximately in its middle length range, through which a guide pin 13 (FIG. 1) mounted in the lock base 1 extends. As a result, the slide switch 10 is guided orthogonally to the longitudinal axis of the bolt 6 in the lock housing.

The interchangeable slide 10 partially overlaps a bolt tail 14. On the side opposite the end face 11, the interchangeable slide 10 is provided with a recess 16 through which a stepped pin 17 engages, which is integrally connected to a bolt guide 18 (FIGS. 25, 26). This bolt guide 18 has in one piece a bearing pin 19 (FIG. 26) which is mounted in a fixed manner in a recess in the lock base 1. Pin 17 and bearing pin 19 are integrally connected to the bolt guide 18. The bolt guide 18 has, on its side facing the bolt head, a toothed rack 20, which meshes with a pinion 21. The pinion 21 also meshes simultaneously with a toothing 22 running parallel to the rack 20, which is integrally connected to a push rod 23 (FIG. 20). The push rod 23 is guided parallel to the inside of the cuff 2 and a limited amount coupled with rods, not shown, which have the locking bolts or the like and which protrude from the lock housing on diametrically opposite sides (not shown).

The push rod 23 has an elongated hole 24 into which a guide pin, which is fastened to the lock base 1 and runs orthogonally to the lock base 1, engages (not shown).

At the opposite end section, the push rod 23 is provided with a further elongated hole 25, through which a guide pin 26, which protrudes orthogonally from the lock base 1, also extends, which is offset at its end for passage through an opening in the lock cover (not shown). The lock cover thus lies on the ring surface of the guide pin 26 formed thereby.

Below the pinion 21, a locking drive 27 is pivotally arranged. The locking drive 27 has a crank 28 and a gear wheel 29 connected to it in one piece, which meshes with the toothing 22 of the push rod 23. The gear 29 is assigned a pin in the center, which in Castle floor 1 is mounted with its longitudinal axis orthogonal to this. A crank pin 30 is firmly connected to the crank 28 and engages in a transverse slot 31 of the bolt tail 14. The transverse slot 31 runs with its longitudinal axis orthogonal to the longitudinal axis of the bolt 6. With a pivoting movement in the direction F, the bolt 6 is closed by the crank 28 from the cuff 2 and with an opposite pivoting movement in the direction E is drawn into the lock case. The bolt tail 14 rests on the crank 28 in all these pivoting movements. Likewise, the bolt head, which is also of greater thickness, rests on the push rod 23 and slides thereon during its inclusion and exclusion movement.

As can be seen in FIGS. 18 and 19, the bolt 6 in its bolt tail 14 also has a slot-like guide opening 32 running parallel to its longitudinal axis, through which a slide pin 33 of the bolt guide 18 extends. The bolt guide 18 is mounted in the lock base 1 with two spaced-apart pins that run orthogonally to the lock base 1 with their longitudinal axes. The sliding pin 33 guides the bolt 6 parallel in the lifting direction.

Characterized in that the pinion 21 meshes simultaneously with the rack 20 and the toothing 22, a translation is achieved which, for example, with a small stroke. B. allows twice the displacement of the push rod 23.

The push rod 23 has a further elongated hole 34 (FIGS. 10 and 20). A rod drive 35 engages in the elongated hole 34, which essentially has a central part 36 and two opposite end parts 37 and 38. The end parts 37, 38 have with their longitudinal axes parallel pins 39 and 40, respectively, the pin 39 engaging in a central opening 41 (FIG. 10) of the pinion 21 and engaging through it. The pin 39 is guided in an elongated hole 42 in the lock base 1. As a result, the pinion 21 is simultaneously guided orthogonally to the longitudinal axis of the bolt on the lock base 1.

The pin 40 extends through the elongated hole 34 of the push rod 23. Below the elongated hole 34, an elongated hole is arranged in the lock base 1, in which the pin 40 engages and is flush with the lock base 1. This is the rod drive 35 is also guided orthogonally to the bolt longitudinal axis or parallel to the cuff 2 on the lock base 1.

In the central area, the rod drive 35 has an approximately U-shaped recess 43 (FIG. 21). The rod drive 35 is formed in one piece in terms of material in the embodiment shown. The parts can also be functionally connected in one piece.

The reference numeral 44 denotes a leaf spring which is mounted on an abutment fixed to the housing and which loads the push rod 23 in the direction of the cuff 2 with a spring leg 46, while another spring leg 47 bears against a part 48 fixed to the housing.

The reference numeral 49 designates a handle mandrel which is designed with the same cross-sectional dimensions, in the present case square, and which is arranged on the inside of the respective door, not shown, and z. B. is connected to a door handle or a knob. The pusher mandrel has a central, axial bore 50 penetrating it, which opens out on both sides of the pusher mandrel at the end.

With 51 a lock nut is designated, the nut lever 52, 53 and 54 has. The longitudinal axes of the nut levers 52 and 53 and the longitudinal axes of the nut levers 53 and 54 each form a right angle with one another. The nut levers 52, 53 and 54 are preferably made in one piece with a nut body 55. The nut body 55 has two slot-shaped depressions 56 and 57 which run parallel to one another and run parallel to the longitudinal axis of the nut lever 53 and which are arranged at the same distance on both sides of the center axis running through the center of the nut body 55.

In addition, an opening 58 penetrating it is arranged centrally in the nut body 55 (FIGS. 29 to 31). The cross-sectional shape of the opening 58 can be seen particularly clearly from FIG. 32. On diametrically opposite sides, this opening 58 is delimited by the same radius 59, so that the opening 58 is rounded on opposite sides. The opening 58 is delimited by 90 degrees and on diametrically opposite sides by plane sides 60 and 61 running parallel to one another. Pages 60 and 61 have of the longitudinal center axis 62 of the opening 58 the same distance. Likewise, at equal distances from the longitudinal center axis 63, which runs orthogonally to the longitudinal center axis 62, the sides 60 and 61 end on opposite sides to the longitudinal center axis 63 at a certain distance and are each widened outward at an obtuse angle α or β. As can be seen from FIG. 32, the longitudinal center axis 62 is pivoted to the left by the angle γ — as seen in the plane of the drawing — while maintaining the radius 59. This results in approximately triangular, sector-like widenings on the opposite sides of the opening 58, into which a pushing mandrel 64, which is to be introduced as a special square and is to be described and is to be described, can be rotated.

The nut body 55 also has nose-shaped projections 65, 66 and 67 which lie on the same circular arc and which protrude from the faces 68, 69 and 70 equally far on the end face and orthogonally to these faces 68 to 70. The surfaces 68, 69 and 70 lie in a same plane running orthogonally to the longitudinal axis of the nut body 55.

The reference numerals 71 and 72 designate guide pins which project equally far and orthogonally from the surface 69 and also project equally over the collar-shaped projections 65, 66 and 67.

The nut levers 52, 53 and 54 are located axially behind the collar-shaped projections 65, 66 and 67.

As can be seen in FIG. 69, the central opening 58 with its approximately triangular or sector-like protrusions or recesses 73 or 74 enters the surface of the slot-shaped recesses 56 or 57. The central web 69 formed between the slot-shaped depressions 56 and 57 has the surface 75.

Reference number 76 (FIGS. 2 and 33) denotes a slide which is delimited on opposite sides by parallel walls 77 and 78. The walls 77 and 78 are delimited on opposite sides by arcs 79 and 79a of the same radius. The slide 76 has an elongated, central opening 80 which is delimited by walls 81 and 82 which run parallel to the walls 77 and 78 and which enclose the opening 80 between them. Walls 81 and 82 too are delimited by arcs 83 and 84 of the same radius. The arcs 83 and 84 each run parallel to the arcs 79 and 80.

The opening 80 is provided centrally with the same sector-shaped extensions 85 and 86 as the nut body 55 (FIGS. 22, 32). The sector-shaped extensions 85 and 86 are the same in shape and dimension as in the nut body 55, so they can, depending on the position of the slide 76, be made to coincide with the central opening 58 in the nut body 55. The slider 76 fits into the slot-shaped recesses 56 and 57 and can be displaced in these in the direction X or Y (FIG. 2) by a limited amount. The circular arcs 83 and 84 form with the collar-shaped projections 65 and 67 stops for the slide 76.

With 87 (Fig. 2 and 27 and 28) is a materially one-piece return part is referred to, with which a lever 88 is integrally connected in terms of material, which is of the same size as the nut lever 52, so that the lever 88 is in alignment when the parts are axially assembled can be brought with the nut lever 52. The return part 87 consists essentially of a plate 89 with diametrical opposite kidney-shaped, slot-like openings 90 and 91, which extend on different sides of the longitudinal central axis 92. A further longitudinal central axis 93 runs orthogonally to this longitudinal central axis 92 and runs centrally through the lever 88. The lever 88 has a nose-shaped projection 94 which is directed onto the nut lever 52. The nose-shaped projection 94 is orthogonal to the surface 95 of the plate 89 (FIG. 28).

The kidney-shaped recesses or openings 90 and 91 each extend over the same angular range, in the present case over an angle δ of approximately 35 to 40 degrees. Through these kidney-shaped recesses 90 and 91, the guide pins 71 and 72 of the nut body 55 fit and guided through.

The return part 87 has a central opening 96, which is likewise delimited by walls 97 and 98 running parallel to one another. The walls 97 and 98 are arranged equidistant from the longitudinal center axis 92 and delimited on diametrically opposite sides by circular arcs 99 and 100, which are also equally spaced from one another the longitudinal center axis 93 and have the same radius. Walls 97 and 98 are flush with walls 81 and 82 of slider 76 (Fig. 33).

Reference number 101 (FIGS. 2 and 12) denotes a nut cover in the form of a plate which has two bores 102 and 103 on diametrically opposite sides which are at the same distance from a longitudinal central axis 104 running through the center of the nut cover 101. Furthermore, the nut cover 101 has a central bore 105. In the exploded view of FIG. 2, the two pins 71 and 72 have been drawn separately from the nut body 55. They are of course arranged in the mounting position in corresponding openings of the nut body 55 and connected in one piece with them.

The special square or pusher mandrel 64 consists essentially of three sections, namely 106, 107 and 108. The front, longer section 108 is circular in cross-section and has a threaded blind bore 110 which penetrates it centrally over a certain length section and which opens out on the front side 109. Section 108 goes into relatively short section 107 above. This section is delimited on diametrically opposite sides by walls 111 and 112 running parallel to one another. The walls 111 and 112 are arranged at the same distance from the longitudinal center axis 113 of the section 107 and are of the same length. The walls 111 and 112 are connected by arcs 114 and 115, which have the same radius. The arcs 114 and 115 are equidistant from the further longitudinal central axis 116, which is orthogonal to the longitudinal central axis 113, and the dimensions have been such that the section 107 fits through the central opening 96 of the return part 87 and also the slide 76 with its opening 80 can grasp. Furthermore, the section 107 engages in the central opening 58 of the nut body 55. Depending on the position of the slide 76, the section 107 can also enter the sector-shaped extensions 85 and 86 of the slide 76 and the sector-shaped extensions 73 and 74 of the nut body 55. The arrangement is such that when the slide 76 moves in the direction X (FIG. 2), the walls 111 and 112 against the corresponding walls 81 and 82 of the slide 76 and the walls 97 and 98 of the return part 87 against the Walls 60 and 61 of the central opening 58 of the nut body 55 abut, so that the return part 87 and the nut body 55 are coupled to one another with virtually no play in the direction of rotation, that is to say cannot be rotated relative to one another.

If, on the other hand, the slide 76 is displaced in the direction Y (FIG. 2), the section 107 with its walls 111 and 112 can enter the sector-shaped recesses 85 and 86 of the slide 76 and into the sector-shaped recesses of the central opening 58 of the nut body 55. As a result, the return part 87, determined by the angular range over which the kidney-shaped recesses 90 and 91 extend, can rotate in the direction of rotation.

The length of the section 108 is dimensioned such that its end face 109 is flush with the end face 117 (FIG. 2) of the presser mandrel 49.

The pusher mandrel 49 can be inserted with its front side opposite the front side 117 into a square opening which is adapted in shape and runs coaxially to the central opening 58 until the front side opposite the front side 117 is flush with an end side Stops wall that lies immediately behind the plane of the central opening with the sector-shaped extensions of the central opening 58 of the nut body 55.

The movement of the slide 76 is controlled by the change slide 10 in the X or Y direction.

The nut lever 52 and the lever 88 lie between two spaced stops 118 and 119 (FIG. 1). In terms of material, the stop 118 is formed in one piece with a sheet metal strip 120 which runs parallel to a side wall 121 projecting orthogonally from the lock base 1 and is guided directly on the inside thereof. With the sheet metal strip 121, an abutment 122 is integrally connected in terms of material, against which a compression spring 123 is supported, which rests at its other end against an abutment 124 fixed to the housing. As a result, the stop 118 has a tendency to move in the direction of the nut lever 52 and the lever 88.

Opposite the stop 118, the stop 119 is arranged, which is connected in one piece to a rod 125 which extends through the spaced guide bearings 126 and 127. A compression spring 128 loads the rod 125 and thus the stop 119 also in the direction of the nut lever 52 and the lever 88, so that the two stops 118 and 119 are spring loaded against each other.

The guide bearings 126 and 127 are arranged fixed to the housing and can be part of a materially one-piece bearing block which extends orthogonally from the lock base 1 and is firmly connected to it.

Reference numeral 129 denotes a latch spring which acts on the latch 5 resiliently outwards, while 130 denotes a slide spring which is designed as a leaf spring and is arranged on a stop 131 fixed to the housing and the slide 76 constantly in the direction Y (FIG. 2 ), so loaded in such a direction and moves it that the lock cannot be opened from the outside of the door again after the door has been locked or the door has slammed without a key.

The operation of the multi-point lock according to the invention is as follows:
Assume that the parts are in the position shown in FIG. 1. Then there is on the inside of the door the arbor 49, z. B. provided with a doorknob, and on the outside of the door, for. B. a front door, the special square 64 with the outwardly facing section 106, the z. B. can be coupled with an olive, a door handle or the like. If the handle pins 49 or 64 are pivoted upwards (seen in the drawing plane of FIG. 1) from the inside or outside, this has the consequence that the nut body 55 and thus the nut levers 52, 53 and 54 in the clockwise direction (at Consideration of Fig. 1) can be pivoted. As a result, the nut lever 54 presses against the inside 132 (FIG. 11) of the rod drive 35 and pulls it down (seen in the plane of the drawing in FIG. 1). The pin 39 moves in the slot of the lock cover 1, in which it is guided. At the same time, the pinion 21 rolls on the toothing 22 of the push rod 23, on the one hand, and on the rack 20, on the other hand, of the bolt guide 18 which is mounted in a fixed manner in the lock housing. In addition, the rod drive 35 slides with its pin 40 in the slot 34 of the lock cover 1. The push rod 23 executes a lifting movement from the lock housing. Through the translation of the pinion, formed from the Rack 20, the pinion 21 and the toothing 22 can be carried out a correspondingly large stroke. For example, it is possible to have the push rod 21 perform the double stroke as it corresponds to the movement which the toothing 20 executes in the lock housing orthogonally to the longitudinal center axis of the bolt 6.

When pivoting the handle mandrel 49 or 64 upwards, the two nut halves, i. H. the nut body 55 and the return part 87, rigidly coupled to one another in the direction of rotation, since the slide 76 is held down by the spring 130, so that there is a positive connection between these parts via the section 107 of the presser mandrel 64.

If, on the other hand, an attempt is made to move the trigger mandrel in the opening direction, e.g. B. Depressing the door handle from the outside, the following happens:

The slide 76 is pressed down by the slide spring 130. This has the consequence that contrary to the Clockwise (in Fig. 1) seen from the side of the arbor 64 - the return member 87 moves empty according to the radians of the kidney-shaped recesses 90 and 91, ie the lock nut is not taken. This is due to the fact that the slider 76, which is moved downward, that is to say in the direction Y (FIG. 2), causes the sector-shaped recesses 85 and 86 of the slider 76 to coincide with the corresponding kidney-shaped recesses of the nut body 55 (FIG. 29). This in turn has the consequence that when the handle 64 is rotated, its section 107 can move into the sector-shaped recesses, that is to say it runs empty with respect to the nut body 55. As a result, neither the push rod 23 nor the bolt or the latch 5 can be moved into the lock housing via the rod drive 35. The lock thus remains closed when actuated from the outside, ie from the side of the handle mandrel 64.

If, on the other hand, a key is inserted into the keyhole 8 and is displaced upward in the direction X (FIG. 2), ie seen in the plane of the drawing in FIG. 1, counter to the restoring force of the spring 130 of the slide 76, via the lock bit 9 and the change slide 10, then the sector-shaped recesses 85 and 86 of the slide 76 are no longer in register with the corresponding recesses in the nut body 55. As a result, the section 107 of the pusher 64 can no longer move empty by a certain angle relative to the central opening 58. This in turn means that the return part 87 and the nut body 55 are integrally coupled to one another in the direction of rotation, which results in a corresponding movement of the nut levers 52, 53 and 54. Thus, if the interchangeable slide 10 is pushed upwards by the key bit 9 and the slide 76 is thereby moved in the direction X, the lock can also be opened from the outside via the pusher mandrel 64, in which the latch 5 and the bolt 6 again via the rod drive 35 can be moved into the lock housing. After opening the lock, the key is turned back so far that the change slide 10 returns under the influence of the spring 130 via the slide 76 to its starting position (FIG. 1), so that after the door slams from the outside of the door The lock can only be opened by an authorized person who has a key. The latch can also be opened by means of the outside handle mandrel 64 then no longer open. If the pusher mandrel is moved upward in the manner described by the person entering the room, the bolt 6 is also excluded and the additional locking elements, such as bolts and pins, are brought into the locking position via the push rod 23. As can be seen, the function is brought about, inter alia, by the special, two-part trigger mandrel 49 and 64, since the two parts 49 and 64 can each be rotated by themselves. The screw coupling the two parts with one another and introduced from the end face 117 thus enables these parts to be rotated relative to one another, at least over the angular dimension resulting from the slot-shaped recesses 90 and 91.

The features described in the abstract, in the patent claims and in the description and apparent from the drawing can be essential for realizing the invention both individually and in any combination.
