Description

The invention relates to an actuating device for a lock with a lock follower, comprising the features of the preamble of claim 1, as well as a locking system for mounting on a door leaf with such an actuating device.

It is known from practice to use handles designed as door handles to operate a lock of a door, which are arranged on both large surfaces of the door and are connected to one another via a polygonal pin. The handles are arranged in a rotationally fixed manner on the polygonal pin, so that a synchronous adjustment movement takes place when one of the handles is actuated. The polygonal pin passes through a lock socket of a mortise lock, which is inserted into a corresponding lock receptacle on the door leaf. The lock follower represents a polygonal receptacle with which the polygonal pin is in positive and non-positive engagement. The polygonal pin is usually designed as a square pin so that the lock follower forms a square receptacle. Particularly in the case of doors to sanitary rooms, such as bathrooms or toilets, it may be necessary to secure the room in question from the inside. Various locking mechanisms are known for this purpose. For example, a lock can be used which has a bolt which can be actuated by means of a key.

The invention is based on the object of creating an actuating device for a lock which enables a door to be locked without a lock bolt having to be actuated by means of a key or the like for this purpose.

According to the invention, this object is achieved by the actuating device having the features of claim 1.

According to the invention, an actuating device for a lock with a lock follower is proposed, comprising a polygonal pin which has a first end region on which a first handle is arranged and a second end region on which a second handle is arranged. The polygonal pin is constructed in several parts and comprises a base pin and a slide which is adjustable relative to the base pin parallel to the axis of the polygonal pin between an engagement position in which it can be brought into engagement with the lock socket and a locking position in which the polygonal pin relative to the lock follower is rotatable.

The slide of the actuating device according to the invention thus establishes the form fit between the polygonal pin and the lock follower. If actuation of the lock follower by means of a handle is to be prevented, the slide can be disengaged with respect to the lock follower. This then corresponds to the locking position of the slide, in which the polygonal pin can be rotated with respect to the lock follower, so that when one of the handles is actuated via the polygonal pin, no torque can be entered in the lock follower.

In a preferred embodiment of the actuating device according to the invention, the slide comprises an engagement portion which can be brought into engagement with the lock nut in the engagement position, and a locking portion which is tapered with respect to the engagement portion and which is rotatable in the locking position with respect to the lock nut. To reach the locking position, the tapered locking section is shifted into the lock follower, whereas in the engagement position in which the lock follower can be actuated by means of one of the handles, the engagement section of the slide is arranged in the lock follower.

In order to ensure a positionally accurate displacement of the slide during adjustment between the engagement position and the blocking position, it is advantageous if the base pin has a guide track for the slide. It is of course also conceivable for the guide track to be implemented by corresponding bevels or the like that are formed on the slide itself.

In a special embodiment of the actuating device according to the invention, the base pin has a taper, in the area of which the engagement portion and the Locking portion of the slide are arranged. The effective area of the slide is thus always arranged in a defined area of the base pin.

In order to be able to move the slide between its end positions, that is to say between the blocking position and the engagement position, it expediently comprises an actuating element which is arranged on the first handle and can be actuated manually. The first handle is therefore preferably the handle which is arranged on the door side that points in the direction of the room to be secured.

For example, the actuating element is a pin which preferably has a radial orientation with respect to the axis of rotation of the polygonal pin, is guided in an elongated hole in the first handle and extends through a wall of the handle. It is also conceivable, however, that the actuating element emerges from the first handle on the front side and can be gripped manually by a user.

In a preferred embodiment of the actuating device according to the invention, the slide on the side of the second handle cooperates with an emergency release device. This ensures that a door can be opened in an emergency, even if the slide initially assumes its blocking position and actuation of the lock follower by means of the second handle is not possible.

In a special embodiment of the actuating device according to the invention, the emergency release device comprises a sleeve arrangement which has a tool attachment element. The sleeve arrangement is particularly accessible from the outside, so that a tool such as a screwdriver or the like can be attached to the tool attachment element and the slide can be moved from the locking position into the engaged position by rotating the sleeve arrangement. Then the lock follower can be turned again by actuating the second handle and the door can be opened. The sleeve arrangement can be pretensioned in the direction of a zero position by means of a return spring, so that it automatically returns to its starting position after actuation

In a special embodiment, the sleeve arrangement comprises a placement surface which cooperates with a placement counter surface which is formed on the slide. at When the sleeve arrangement is rotated, the footprint and the counter-surface interact in such a way that the slide is pushed away from the sleeve arrangement.

For example, the counter surface is formed on an end face of the slide, which is preferably formed by a slide attachment. It is of course also grateful that the counter surface is realized without an attachment on the slide.

The support surface and the counter surface can each be formed on a wedge-like section which has a recess into which the base pin engages.

In order to be able to adapt the emergency release device to different geometries of handles, it is advantageous if the sleeve arrangement comprises an inner sleeve and an outer sleeve which is arranged non-rotatably with respect to the inner sleeve and can be displaced in the axial direction. The outer sleeve forms, for example, the tool attachment element to which a tool can be attached. Depending on the geometry of the second handle, the depth of insertion of the inner sleeve into the outer sleeve can vary. The position of the sleeve cooperating with the slide relative to the base pin is fixed. Furthermore, the outer sleeve can have an annular collar or other shoulder, via which it rests from the inside against a counter-bearing of the second handle. In addition, the outer sleeve can be pressed against the counter bearing by means of a spring, which is supported on the inner sleeve.

In a special embodiment of the actuating device according to the invention, the base pin engages in the sleeve arrangement, the sleeve arrangement being rotatable with respect to the base pin and preferably secured to the base pin in the axial direction.

The invention also relates to a locking system for mounting on a door leaf, which comprises a lock with a lock follower and an actuating device of the type described above. The polygonal pin of the actuating device passes through the lock follower, the slide being displaceable parallel to the axis of the polygonal pin relative to the base pin in such a way that it engages the lock follower in the engagement position and can be rotated relative to the lock follower in the locked position.

Further advantages and advantageous embodiments of the subject matter of the invention can be found in the description, the drawing and the claims.

In Figure 1 a door leaf 10 is shown, which is provided with a lock system 12 shown in an exploded view. The lock system 12 comprises a mortise lock 14 which is inserted into a recess 16 in the door leaf 10 which is formed on a longitudinal edge of the door leaf 10. The mortise lock 14 has a lock follower 18 which forms a square receptacle and is accessible via recesses 20 which are formed on the two large surfaces of the door leaf 10.

The lock system 12 comprises an actuating device 22 which has a first handle 24, which is fastened to the large surface of the door leaf 10 facing the room to be locked, and a second handle 26 which is fastened to the large surface of the door leaf 10 facing away from the room to be locked . The first handle 24 is pushed onto a first end region of a polygonal pin 28 and is thus connected to it in a rotationally fixed manner. The second handle 26 is pushed onto a second end region of the polygonal pin 28 and is thus also connected to it in a rotationally fixed manner. The polygonal pin 28 serves to transfer the adjustment forces entered in the handles 24 and 26 to the lock socket 18, so that an actuation of the handles 24 and 26 leads to an actuation of a latch 30 of the mortise lock 14.

The polygonal pin 28, which extends through the lock follower 18, is constructed in several parts and comprises a base pin 32 which is inserted into the Figures 3 to 5 Is shown in isolation, and a slide 34, which in the Figures 6 to 8 is shown in isolation. The slide 34 rests on the top of the base pin 32 and is in guideways 36 of the base pin 32 is guided in such a way that it can be displaced parallel to the axis of rotation of the polygonal pin 28 with respect to the base pin 32. For guidance in the guide tracks 36 of the base pin 32, the slide 34 has two strip-like guide sections 38 and 40, between which an active section 42 is arranged. The active portion 42 comprises a locking portion 44 and an engaging portion 46. How Figure 9 As can be seen, the engagement section 46 has a U-shaped cross section, the outer dimensions and angles of which correspond to the inner dimensions of the lock follower 18. When the engagement section 46 is arranged in the lock socket 18 and one of the handles 24 and 26 is actuated, the latch 30 is actuated. The locking section 44 has, as Figure 8 can be seen, an arcuate cross-section, the radius of which is selected such that it can rotate freely together with the base pin 32 when arranged in the lock socket 18 and when one of the handles 24 and 26 is actuated, without actuating the latch 30 is coming. This position of the slide 34 corresponds to the blocking position, whereas the position of the slide 34 in which the engagement section 46 is arranged in the lock follower 18 corresponds to the engagement position.

In order to be able to adjust the slide 34 between the engagement position and the blocking position, an actuating pin 48 is fastened in a bore 50 on the guide section 38 in one end region. The actuating pin 48 has a radial alignment and extends through an elongated hole 52 which is formed on a shaft section of the handle 24 and extends parallel to the axis of the polygonal pin 28. The actuating pin 48 is thus manually graspable for a user. The elongated hole 52 has a length which corresponds to the adjustment path of the slide 34 between the engagement position in which the latch 30 can be actuated and the blocking position in which the polygonal pin 28 rotates empty when one of the handles 24 and 26 in the lock follower 18 is actuated and the latch 30 is not actuated.

In order to be able to bring the slide 34 from the side of the handle 26 into the engaged position in an emergency situation, the actuating device 22 is provided with an emergency release device 54, which can be actuated by means of a screwdriver or the like that can be attached to a slot 56, which is accessible from the end face of the second handle 26.

The emergency release device 54 comprises a sleeve arrangement which is rotatably mounted on an end region 58 of the base pin 32 and comprises an inner sleeve 60 and an outer sleeve 62 which receives the inner sleeve 60 and is inserted into a corresponding receptacle 64 of the handle 26. The outer sleeve 62 has an end face 66 on which the slot 56 for the tool is formed and which is shaped such that it is flush with the surface of the handle 26 which delimits the receptacle 64. Furthermore, the outer sleeve 62 has an elongated hole 68 on its circumference, through which a screw 70 penetrates, which is screwed into a thread 72 of the inner sleeve 60, so that the inner sleeve 60 and the outer sleeve 62 are connected to one another in a rotationally fixed manner. An axial offset between the inner sleeve 60 and the outer sleeve 62 is guaranteed. This allows tolerances to be compensated. In addition, an adaptation to other handle or handle geometries and / or other door thicknesses is possible.

The inner sleeve 60 has an annular collar 74, in the area of which is arranged a transverse threaded bore 76 into which a screw 78 is screwed, the end face of which engages in an annular groove 80 which is formed on the base pin 32 in its end area 58. The inner sleeve 60 is thus secured against axial displacement on the base pin 32, but is rotatably mounted.

The annular collar 74 of the inner sleeve 60 is wedge-shaped and has two wedge surfaces 82 arranged mirror-symmetrically to one another. The two wedge surfaces 82 are interrupted by a blind hole 84 which is introduced into the inner sleeve 60 in an axial arrangement on the side facing away from the outer sleeve 62. By means of the blind hole 84, arcuate placement surfaces 86 are realized in the area of the wedge surfaces 82. The wedge surfaces 82 also form storage surfaces.

The slide 34 has on the end face facing the emergency unlocking device 54 an attachment 88 which is inserted into the Figures 10 and 11 is shown in isolation and could also be made in one piece with the slide 34. The attachment 88 is designed in the manner of a sleeve and comprises a through opening 90 through which the end region 58 of the base pin 32 extends, and on the upper side a recess 92 which is used for a fixed connection to the slide 34. In relation to the zero position of the polygonal pin 28, in which the handles 24 and 26 are not actuated, the attachment 88 wedge surfaces 94 which are arranged mirror-symmetrically to one another with respect to a vertical longitudinal center plane and which are interrupted by the through opening 90 which extends through the attachment 88. This results in counter surfaces 96 which represent ramps and which interact with the wedge surfaces 82 of the inner sleeve 60. The wedge surfaces 94 form opposing surfaces that interact with the surfaces of the inner sleeves 60.

The emergency actuation device 54 operates in the manner described below.

Starting from the locked position of the slide 34, in which the polygonal pin 28 is freely rotatable in the lock socket 18, the inner sleeve 60 is rotated about its axis by means of a screwdriver which is placed in the slot 56 of the outer sleeve 62. As a result of the interaction of the wedge surfaces 82 and 94, the positioning surfaces 86 and the positioning counter surfaces 96, the slide 34 is displaced in the direction of the handle 24. The engagement section 46 of the slide 34 is thus displaced into the lock socket 18, which in turn enables the latch 30 to be actuated and the door leaf 10 to be opened when the handle 26 is actuated and the polygonal pin 28 is rotated. The sleeve arrangement made up of the inner sleeve 60 and the outer sleeve 62 can now be turned back into its starting position by means of the screwdriver. The slide 34 can thus be adjusted again by means of the actuating pin 48 between the engagement position and the blocking position.
