Description

Field of the invention

The present invention relates to a door fitting structure for a hinged door.

Background of the invention

Door fitting structures for hinged doors with locking devices for automatically moving the door leaf back to a closed position of the door leaf are known. The locking mechanisms of known locking devices usually have a plurality of components, which increases the cost, and require large dimensions of the locking devices for accommodating the components.

A variant of known locking devices is described e.g. provided in the form of floor door closers, which are embedded with their entire housing in a recess in the floor below the door, but in the ground below the door requires a corresponding space that should be provided already in the construction of the floor or in the ground, in particular in concrete floors, can be introduced later only at a correspondingly high cost. In another variant of known locking devices, in which the locking mechanism is integrated in the door fitting mounted on the door, the integration of the locking mechanism usually requires an increase in the dimensions and weight of the door fitting and a usually large and depending on the manufacturer special mounting cutout on the door leaf.

Due to the associated with the known locking devices disadvantages in terms of the required space in the floor below the door or the required size and special shape of the mounting cut on the door, it is therefore costly and expensive to retrofit existing door with such known locking devices, as subsequently corresponding recesses for the entire housing must be introduced into the ground or the door must be provided with appropriate special mounting cutouts, even if on the door already a smaller mounting portion with standard dimensions for the door fitting originally mounted on the door without closing mechanism is present.

Furthermore, another door fitting for automatic door operation for glass doors from the DE 2 327 389 A known, which is formed by two asymmetrical parts for insertion of reduced mechanisms for the elastic return and the hydraulic braking in the larger of the two parts.

In addition, from the GB 404 854 A another door fitting for a door is known in which a pivot pin has a plurality of longitudinal grooves, in which a latching element can engage to hold the door in a position.

From the US 2010/0199459 A1 For example, a door fitting structure for a self-closing door is known in which closing means and hydraulic damping means are housed in a working chamber in a stationary part mounted on the frame of a door.

Other door hardware and door fitting structures are for example from the US 6 161 255 A and the US 5 867 869 A known.

Explanation of the invention

The invention provides a door fitting structure which solves the abovementioned problems completely or at least partially. The invention provides, among other things, a door fitting structure with a compact construction, which makes it possible to mount the door fitting structure on existing door leaves without having to change the assembly cutout present thereon. The door fitting structure of the present invention further provides a closing function to the door leaf while providing a high door holding force (e.g., about 300kg). Furthermore, the door fitting structure according to the invention has improved control of the movement of the door leaf and can both allow opening the door in two directions and prevent excessive overshooting of the door leaf beyond a desired open position.

To this end, the present invention provides a door fitting structure (e.g., a door hinge structure) for a hinged door panel according to claim 1.

Further embodiments of the door fitting structure according to the invention are described in the dependent claims.

According to various aspects of the present invention, a door fitting structure (eg, a door hinge structure) includes a stationary part for stationary attachment to a door adjacent to the door and a rotation member for fixed attachment to the door, which is rotatably connected to the stationary part about a rotary part rotation axis and the one having inner chamber. The door fitting structure further comprises a mechanical indexing device (eg a device for the Resetting in at least one rotational position), by means of which at least one (eg predetermined) rotational position of the rotary member is mechanically indexable about the rotary part rotation axis relative to the stationary part and which is housed in the inner chamber of the rotary part. The indexing device has a piston body which is slidably disposed in the inner chamber of the rotary member in a direction transverse to the rotary member rotation axis and which is provided with a contact member for (permanently) contacting a contact portion of the stationary member, the contact portion in the inner chamber is arranged and at least one Indexiermulde, in which the contact element for indexing the at least one rotational position can engage releasably. Furthermore, the indexing device comprises a disc spring device, which has at least one disc spring and is accommodated in the inner chamber of the rotary part and by means of which the piston body is spring-biased in the direction transverse to the rotational part rotational axis to the contact of the contact element with the contact portion spring-biased (eg always) maintain. The contact section has a cam profile in cross-section transverse to the rotation part rotation axis, so that a torque is generated via the spring-biased contact contact of the contact element with the contact section to move the rotation part relative to the stationary part about the rotation part rotation axis into the at least one rotational position (eg automatically). rotating reset.

By means of the use of disc springs, a compact design of the door fitting structure according to the invention can be realized. Among other things, the compact construction makes it possible to dimension the door fitting structure according to the invention so that already assembled door leaves can be retrofitted cost-effectively and without great effort with the door fitting structure according to the invention (eg because the dimensions of the door fitting structure according to the invention are chosen to match a mounting cutout already present on the door leaf) and little or no adjustments to the existing on the door panel cutout are required). This makes it possible, for example, previously non-self-closing doors simple and inexpensive to convert into self-closing doors.

The at least one indexing recess may include a first indexing recess formed in the contact portion of the stationary part and in which the contact element for indexing a first rotational position of the rotating part about the rotary part rotation axis relative to the stationary part can detachably engage, and may have a second indexing recess which is in the contact portion of the stationary part at an angular distance, optionally formed at an angular distance of at least substantially 90 degrees to the rotary part rotation axis to the first indexing recess and in which the contact element for indexing a second rotational position of the rotary member to the rotary part rotation axis relative to the stationary part releasably engage can. The cam profile may include a first cam profile surface connecting a first side of the second indexing recess to the first indexing recess and curved about the rotary part rotation axis such that torque is generated about the spring biased contacting contact of the contact element with the first cam profile surface around the rotation part relative to the stationary part about the rotation part rotation axis in the first rotational position drehrückzustellen. The first indexing trough may be lower than the second indexing trough.

By providing a first and a second Indexiermulde angular distance from one another, a first and a second rotational position of the rotary member can be defined by the door fitting structure according to the invention by the contact element in the respective rotational position in the associated Indexiermulde releasably engaged. Thus, for example, by means of the first rotational position, a first position (eg, a closed position) of a door leaf connected to the rotary part can be defined and the door leaf can be detachably held in the first position, and by means of the second rotational position, a second position (eg, a completely open position). Position) of the door and defines the door in the second position are releasably held. By allowing the first indexing tray to be deeper than the second indexing tray, the required initial effort to move the door out of the first rotational position for the first rotational position relative to the second rotational position may be increased and, for example, more clearly define the closed position of the door leaf.

The cam profile may further include a second cam profile surface extending from a second side opposite the first side of the second index recess from the second index recess and curved about the rotation part rotation axis such that via the spring biased contact contact of the contact element torque is generated with the second cam profile surface to return the rotation member relative to the stationary member about the rotation member rotation axis toward the second rotation position. The second cam profile surface may be curved such that the torque generated via the spring-biased contact contact of the contact element with the second cam profile surface increases with increasing angular distance of the contact element from the second side of the second Indexiermulde. For example, the second cam profile surface may be curved such that at a predetermined angular distance of the contact element from the second side of the second Indexiermulde an increase in the angular distance of the contact element from the second side of the second Indexiermulde is prevented, and thus further rotation of the rotary member is blocked relative to the stationary part.

By generating a torque upon contact of the contact element with the second cam profile surface (eg, when rotating the rotary member relative to the stationary member from the first rotational position toward the second rotational position and then rotating beyond the second rotational position), in order to return the rotary member relative to the stationary member about the rotary member rotary axis toward the second rotary position, excessive overshooting of the door panel connected to the rotary member (eg, excessive overshooting beyond the fully open position) may be reduced by the second cam profile surface. As a result, damage to the door leaf can be avoided by excessive overshoot, for example damage by collision of the door leaf with an obstacle in the rotation area beyond the fully open position. At the same time, a certain degree of overshoot may be allowed and the generated restoring torque correspondingly increased, so as not to create a hard stop, which reduces a risk of damaging the door leaf, especially in the case of a glass door leaf.

The at least one Indexiermulde may further comprise a third Indexiermulde which is formed in the contact portion of the stationary part at an angular distance, optionally at an angular distance of at least substantially 90 degrees to the first Indexiermulde in the direction opposite to the second Indexiermulde about the rotary part rotation axis (eg second Indexiermulde is arranged opposite) and in which the contact element for indexing a third rotational position of the rotary member to the rotational part rotational axis relative to the stationary part can detachably engage. A first side of the third indexing recess may be connected to the first indexing recess by means of a third cam profile surface, and a fourth cam profile surface may extend away from the third indexing recess from a second side of the third indexing recess opposite the first side. The third may be configured analogously to the above-described first cam profile surface and accordingly rotationally return the rotary member relative to the stationary member about the rotary member rotation axis to the first rotary position, and the fourth cam profile surface may be configured analogously to the second cam profile surface described above and correspondingly rotate the rotary member relative to the stationary member Rotate the rotary part rotation axis in the third rotational position.

By providing first, second and third Indexiermulde, as described above, a double-sided swinging of the door leaf about the first rotational position with corresponding indexing in the three different rotational positions and a corresponding return to the rotational positions can be realized. Furthermore, excessive overshoot over the second and third rotational positions can be prevented.

The piston body may comprise a sleeve portion which at least partially surrounds the disc spring means for guiding the at least one disc spring of the disc spring means. The sleeve portion may extend, for example, in the direction opposite to the biasing force of the disc spring device. The sleeve portion may have a sleeve portion inner surface with which an outer periphery of the at least one plate spring of the Belleville washer comes in contact so that the outer periphery of the at least one plate spring of the Belleville washer is guided by the sleeve portion inner surface. By means of the sleeve portion, the disc spring device can be guided in the inner chamber, in order to avoid tilting of plate springs of the disc spring device, and can the direction of the biasing force of the cup spring device are precisely aligned.

The rotary member may further include a guide pin disposed in the inner chamber and extending through a central opening of the at least one Belleville spring of the Belleville washer means for guiding the at least one Belleville spring of the Belleville spring mechanism. Further, the rotary member may have a side shutter closing a lateral opening of the rotary member (eg, the body of the rotary member) communicating with the inner chamber and having a shutter guide portion at least partially surrounding the Belleville spring mechanism to guide at least one plate spring of the disc spring device. For example, the shutter guide portion may extend in the direction of the biasing force of the cup spring device, and may have a guide portion inner surface to which an outer periphery of the at least one plate spring of the cup spring device comes into contact so that the outer periphery of the at least one plate spring of the cup spring device is guided by the guide portion inner surface. The guide pin may be attached to a central portion of the side closure. By means of the guide pin and / or the closure guide portion, the guidance of the disc spring device in the inner chamber can be further improved and the direction of the biasing force of the disc spring device can be aligned even more precisely.

The piston body may further divide the inner chamber into a first chamber portion and a second chamber portion. The first chamber portion and the second chamber portion may each have a variable volume by the displacement of the piston body in the inner chamber. For example, the volume of the first chamber portion is greater than the volume of the second chamber portion when the contact element of the piston body in the first indexing recess is engaged, and the volume of the first chamber portion is smaller than the volume of the second chamber portion, when the contact element of the piston body in the second Indexiermulde is engaged.

The door fitting structure may comprise a hydraulic device, which is housed in the inner chamber of the rotary member and is adapted to counteract a rotational movement of the rotary member relative to the stationary part damping. The hydraulic device may include a damping fluid housed in the inner chamber of the rotating member. The damping fluid may be, for example, a hydraulic oil. The hydraulic device may further comprise a first channel formed in the piston body and fluidly communicating the first chamber portion and the second chamber portion, and a first check valve disposed in the first channel and configured such that upon displacement of the piston body Direction against the biasing force of the disc spring device, the damping fluid from the first chamber portion can flow through the first channel into the second chamber portion and that upon displacement of the piston body in the direction of the biasing force of the Belleville spring device, a flow of the damping fluid from the second chamber portion through the first channel in the first chamber portion is blocked, have. The hydraulic device may further comprise a second passage formed in the rotation member (e.g., in a body of the rotating member) and fluidly communicating with (e.g., bypassing the piston body) the first and second chamber portions. The second channel may at least partially have a smaller channel cross-section than the first channel.

By the flow of the damping fluid between the first and the second chamber portion by means of the first and the second channel damping of rotational movement of the rotary member relative to the stationary part can be achieved. For example, the displacement of the piston body in the direction of the biasing force of the disc spring device is counteracted damping by the damping fluid can flow only through the second channel, and is consequently counteracted by the rotational movement of the rotary member relative to the stationary part damping.

The hydraulic device may further comprise a control valve which is arranged in the second channel and by means of which the flow of the damping fluid is adjustable through the second channel. By the control valve, a maximum possible flow of the damping fluid through the second channel can be adjusted. The control valve may, for example, have a frusto-conical shut-off section, which is arranged at least partially in the second channel and by means of which the flow of the damping fluid through the second channel is adjustable. For example, by means of the control valve, the second channel can be completely closed and the flow of the damping fluid through the second channel can be completely blocked so that the rotary part can not move back into the first rotational position relative to the stationary part.

The hydraulic device may further include a third passage formed in the piston body (eg, in the direction of the rotational part rotation axis above the first passage) and fluidly communicating the first chamber portion and the second chamber portion with each other and a second check valve disposed in the third passage and is arranged so that the damping fluid from the second chamber portion can flow through the third channel into the first chamber portion, when a displacement of the piston body in the direction of the biasing force of the cup spring device, a pressure of the damping fluid in the second chamber portion exceeds a predetermined pressure , and that upon displacement of the piston body in the direction opposite to the biasing force of the disc spring device, flow of the damping fluid from the first chamber section through the third passage into the second chamber section is blocked. By means of the second check valve can be prevented that a displacement of the piston body in the direction of the biasing force of the Belleville washer causes excessive pressure in the second chamber portion (for example, leads to damage of the components of the door fitting structure), when a displacement of the piston body in the direction of the biasing force the cup spring means the damping fluid can no longer flow through the second channel from the second chamber portion into the first chamber portion. By means of the second check valve, damage to the components of the door fitting structure can be prevented in such a situation.

The piston body may be provided with a mating contact element, which is arranged at a distance from and with respect to the rotation part rotation axis R1 relative to the contact element. The counter-contact element is arranged on the piston body, so that when a rotational movement of the rotary member relative to the stationary part in the first rotational position applied by the damping fluid to the piston body in the direction against a spring force of the disc spring counterforce (eg damping force) at least substantially equal to or greater the spring force applied by the disc spring device to the piston body is the mating contact element with the cam profile of the contact section (eg with the second cam profile surface at a Drehbwegung from the third rotational position to the first rotational position or with the fourth cam profile surface at a Drehbwegung from the second rotational position to the first rotational position) comes into physical contact to aufz by means of the contact contact between the mating contact element and the cam profile of the contact portion, a force on the piston body in the direction of the biasing force of the cup spring device bring, so that the piston body is displaced in the inner chamber in the direction of the biasing force of the disc spring means. For example, the mating contact element may be a counter-roller, which is rotatably connected to the piston body (eg, to the first piston body part) about a counter-roll rotation axis parallel to the rotation-part rotation axis and to the roll rotation axis. By way of example, the counter-roller can be rotatably connected to the one with the first piston-body part of the piston body by means of a counter-roller rotating shaft. By means of the mating contact element, the first rotational position can be indexed faster and more reliably, since the contact element can be more reliably engaged with the first indexing recess. Thus, it can be more effectively prevented that the rotary member rotates beyond the first rotational position.

The stationary part may be formed as a spindle extending along the rotation part rotation axis, optionally formed as one piece (eg, integral with material), which has the contact part located inside the inner chamber and which outward from the rotation part along the rotation part rotation axis protruding mounting portion for stationary attachment at a location adjacent to the door wing has.

The contact element may be a roller which is rotatably connected to the piston body about a roller rotation axis parallel to the rotation part rotation axis and which rolls on the contact portion when the rotation part moves relative to the stationary part. It is also possible that the contact element is fixedly connected to the piston body and slides on a movement of the rotary member relative to the stationary part of the contact portion along.

The rotary member may further comprise an elongated body in which the inner chamber is formed. The main body may include a body recess formed in an outer surface of the main body and extending along a first side of the outer surface along a rotational part longitudinal axis extending transversely to the rotary member rotation axis, and a support protrusion projecting from the outer surface of the main body and abutting one another to the first side opposite the second side of the outer surface along the rotational part longitudinal axis extending. Further, the rotary member may include a mounting plate which is inserted into the body recess and is connected by means of at least one first fastening means to the base body for holding the door leaf between the mounting plate and the support projection. The door fitting structure may further include a second attachment means for engaging an opening in the door panel connecting the attachment plate to the support projection. By means of the mounting plate and the support body, a high (for example with conventional fittings without closing function comparable) holding force for the door between the mounting plate and the support body can be realized.

The rotary member may be elongated in the direction transverse to the rotary member rotation axis and define a corresponding rotary member longitudinal axis. The inner chamber may be elongated along the rotational part longitudinal axis. The piston body may be formed elongated along the rotation part longitudinal axis. The disc spring device can furthermore be designed to be elongated along the rotational part longitudinal axis, wherein the direction of the pretensioning force of the disc spring device can be at least substantially aligned with the rotational part longitudinal axis.

By making the rotary member, the inner chamber, the piston body and the Belleville spring apparatus elongated along the same axis as described above, the door fitting structure of the present invention can be even more compact.

The disc spring device may comprise a plurality of disc springs. The disc spring device may comprise a plurality of plate spring packets (eg at least or exactly one, two, three, four, five, six, seven, etc. plate spring packets), each having a plurality of disc springs and which are arranged one behind the other in series. For example, each plate spring package at least or exactly one, two, three, four, etc. disc springs, wherein the individual plate springs of the plate spring packets to each other in series and / or parallel connection are arranged. The plate springs may, for example, from the same or from respectively different spring steel and may each have the same or different spring hardness.

A door pivot axis of rotation can at least substantially be aligned with the rotation part rotation axis.

The door may further include a door frame surrounding the door leaf and a floor (e.g., a door sill) disposed below the door sash. For example, the stationary part may be located above the door leaf, e.g. on the door frame of the door, or at a location below the door leaf, e.g. be firmly attached to the floor below the door leaf. For mounting the stationary part on the floor, for example, a base mounting plate can be provided, which can be inserted into a recess already present in the floor or fastened to the floor by means of fastening means (eg screws, glue, nails, etc.) and with which the stationary part can be fixedly connected , The floor mounting plate may also include an alignment mechanism, for example with slots for adjusting the position of the stationary part in the floor mounting plate.

The contact element 52 can be rotatable with the second piston body part 56 be connected. The first and the second piston body part 54 and 56 are by means of a connection section 58 connected with each other. As shown in the figures, the stationary part 20 in the exemplary embodiment of the door fitting structure 10 between the first piston body part 54 and a second piston body part 56 arranged and extends through a in the connecting portion 58 trained slot (not shown).

Furthermore, the piston body 50 the inner chamber 42 in a first chamber section 44 and a second chamber portion 45 divide. For example, the piston body 50 at least one piston-body sealing element 46 have, which on the outer circumference of the piston body 50 , For example, on the outer circumference of the first piston body part 54 , is attached and which a gap between the piston body and the inner chamber 42 defining inner surface of the rotating part 40 fluid-tight seals. The first chamber section 44 and the second chamber portion 45 each one by the displacement of the piston body 50 variable volume in the inner chamber. For example, the volume of the first chamber section 44 greater than the volume of the second chamber section 45 when the contact element 52 of the piston body 50 in the first indexing trough 24 is engaged, and is the volume of the first chamber section 44 smaller than the volume of the second chamber section 45 when the contact element 52 of the piston body 50 in the second indexing trough 25 is engaged. The first chamber section 44 may further include a spring chamber portion in which a cup spring device 60 (will be described in more detail below) may be arranged, and a stationary part chamber area in which the stationary part 20 may be arranged. The spring chamber area and the stationary part chamber area may be defined by the second piston body part 56 be separated from each other and can by means of a through hole 57 in the second piston body part 56 be fluidly connected. The volume of the spring chamber portion and the volume of the stationary portion chamber portion may correspond to the volume change of the first chamber portion 44 to be changeable.

The door fitting structure 10 also has a cup spring device 60 on which at least one plate spring 62 and in the inner chamber 42 of the rotary part 40 is housed. The disc spring device 60 is for example in the first chamber section 44 , For example, in the spring-chamber area, housed as in 3 and 5 shown. The disc spring device 60 clamps the piston body 50 in the direction transverse to the rotation part rotation axis R1 by means of a spring force of the at least one plate spring before the contact of contact of the contact element 52 with the contact section 22 maintain spring biased. For example, the biasing force of the disc spring device (eg directly) acts on the second body part 56 of the piston body 50 , The disc spring device 60 may further be formed elongated along the rotational part longitudinal axis L, wherein the direction of the biasing force of the disc spring means 62 at least substantially to the rotational part longitudinal axis L can be aligned. As in the 4 to 7 is shown, the disc spring device 60 have a plurality of disc springs, which are present in a plurality of plate spring packets. In the exemplary embodiment of the door fitting structure shown in the figures 10 has the cup spring device 60 a plurality of plate spring assemblies arranged in parallel to one another, each plate spring packet consisting of two disk springs arranged in series with one another 62 has (see in particular 4 to 7 ).

The contact section 20 also has a cross-section transverse to the rotation part rotation axis R1 a cam profile (see, eg 4 and 6 ), so that via the spring-biased touch contact of the contact element 52 with the contact section 22 a torque is generated around the rotation part 40 relative to the stationary part 20 to return the rotary part rotation axis R1 to the at least one rotational position. The cam profile may have a first cam profile surface 26 having a first side of the second Indexiermulde 25 with the first indexing recess 24 combines. The cam profile surface 26 is curved about the rotary part rotation axis R1, so that via the spring-biased touch contact of the contact element 52 with the first cam profile surface 26 a torque is generated around the rotation part 40 relative to the stationary part 20 to return the rotary part rotation axis R1 to the first rotary position. The cam profile surface 26 can, for example, arcuate, for example along a cross-section transverse to Rotational part rotation axis R1 at least substantially elliptical orbit to extend around the rotation part rotation axis R1, wherein a distance of the cam profile surface 26 from the rotary part rotation axis R1 (eg, a radius of curvature of the cam profile surface 26 ) with increasing angular distance from the first Indexiermulde 24 out to the second Indexiermulde 25 increases.

The cam profile may further include a second cam profile surface 28 which extends from a second side of the second Indexiermulde 25 , which is arranged opposite to the first side of extending from. The second cam profile surface 28 is curved, for example, about the rotation part rotation axis R1 such that via the spring-biased touch contact of the contact element 52 with the second cam profile surface 28 a torque is generated to reset the rotary member relative to the stationary member about the rotary member rotation axis R1 toward the second rotary position. The second cam profile surface 28 For example, is curved such that the over the spring-biased touch contact of the contact element 52 with the second cam profile surface 28 generated torque with increasing angular distance of the contact element 52 from the second side of the second indexing tray 25 increases. To a relative rotation of the rotating part 40 relative to the stationary part 20 To limit, the second cam profile surface 28 be curved such that at a predetermined angular distance of the contact element 52 from the second side of the second indexing tray 25 an increase in the angular distance of the contact element 52 from the second side of the second indexing tray 25 is prevented and consequently a further rotation of the rotary member 40 relative to the stationary part 20 is blocked. For example, the second cam profile surface 28 arc-shaped, for example, along a path which is at least substantially elliptical in cross section transverse to the rotation part rotation axis R1, extend around the rotation part rotation axis R1, and may be a distance of the second cam profile surface 28 from the rotary part rotation axis R1 (eg, a radius of curvature of the second cam profile surface 28 ) with increasing angular distance from the second side of the second indexing recess 25 increase such that at a predetermined angular distance of the contact element 52 from the second side of the second Indexiermulde 25 a maximum possible displacement of the contact element 52 in the direction opposite to the biasing force of the disc spring device 60 is reached.

In the exemplary embodiment of the door fitting structure 10 For example, as shown in the attached figures, the cam profile additionally has a third indexing recess 30 on which in the contact section 22 of the stationary part 20 at an angular distance, optionally at an angular distance of at least substantially 90 degrees, to the first Indexiermulde 24 in the direction opposite to the second Indexiermulde 25 is formed around the rotary part rotation axis R1. The contact element 52 can be used to index a third rotational position of the rotating part 40 around the rotary part rotation axis R1 relative to the stationary part 20 detachable in the third Indexiermulde 30 engage, wherein the third rotational position of the second rotational position is arranged opposite, for example, at an angular distance of 180 degrees to the second rotational position. A first page of the third indexing trough 30 is by means of a third cam profile surface 32 with the first indexing recess 24 connected, and a fourth cam profile surface 34 extends from a second side of the third indexing recess opposite the first side 30 from the third Indexiermulde 30 away, with the third and fourth cam profile surface 32 and 34 each analogous to the first and the second cam profile surface 26 and 28 are formed, so that a repeated description can be omitted. By providing both the second and third indexing troughs 25 and 30 in addition to the first indexing recess 24 it is possible that by means of the second Indexiermulde 25 the rotation part 40 after a relative rotation, which with respect to the stationary part 20 from the first rotational position in a first rotational direction, can be held in a second rotational position and by means of the second Indexiermulde 25 the rotation part 40 after a relative rotation, which with respect to the stationary part 20 from the first rotational position takes place in a second rotational direction opposite to the first rotational direction, can be held in a third rotational position, wherein by means of the first and the third cam profile surface 26 and 32 an automatic return of the rotary part 40 is performed in the first rotational position. Thus, a double-sided pivoting of the rotating part 40 around the first rotational position relative to the stationary part 20 to be controlled. By means of the second and the fourth cam profile surface 28 and 34 may also be a rotation of the rotary member 40 relative to the stationary part 20 beyond the second or third rotational position and consequently an overshooting of the door leaf 2 be limited.

The door fitting structure 10 according to the present invention, as shown in the attached figures, may further comprise a hydraulic device, which in the inner chamber 42 of the rotary part 40 is housed and adapted to a rotational movement of the rotary member 40 relative to the stationary part 20 counteract dampening.

The hydraulic device has a damping fluid that is in the inner chamber 42 of the rotary part 40 is housed. The damping fluid may be, for example, hydraulic oil. The damping fluid may, for example, in the first chamber section 44 present in the spring chamber area as well as in the stationary part chamber area and over the through hole 57 flow between the spring chamber area as well as in the stationary part chamber area. This allows the damping fluid to lubricate the piston body 50 and to the disc spring device 60 provide.

The hydraulic device has, as in 3 and 5 shown a first channel 70 on which in the piston body 50 is formed and which the first chamber section 44 and the second chamber portion 45 fluidly interconnected. The first channel 70 is for example in the first piston body part 54 of the piston body 50 at least substantially along the rotational part longitudinal axis L is formed. The hydraulic device also has a first check valve 72 on, in the first channel 70 is arranged. The first check valve 72 is set up so that upon displacement of the piston body 50 in the direction opposite to the biasing force of the disc spring device 60 the damping fluid from the first chamber section 44 through the first channel 70 through into the second chamber section 45 can flow in and that during a displacement of the piston body 50 in the direction of the biasing force of the disc spring device 60 a flow of the damping fluid from the second chamber portion 45 through the first channel 70 through into the first chamber section 45 is blocked.

The hydraulic device also has a second channel (eg, a chamber section connecting channel) 74 which is in the rotary part 40 is formed and the first chamber section 44 and fluidly interconnecting the second chamber portion 45. The second channel 74 is for example in the main body 41 bypassing the piston body 50 (Eg bypassing the first piston body part 54 ) educated. The channel cross section of the second channel 74 can (for example, in sections or along the entire length of the second channel 74 ) be less than the channel cross section of the first channel 70 ,

The hydraulic device may be a control valve 76 that in the second channel 74 is arranged, wherein by means of the control valve 76 the flow of damping fluid through the second channel 74 through is adjustable. By means of the control valve 76 may be a maximum possible flow of the damping fluid through the second channel 74 be adjusted through. The control valve 76 For example, a frusto-conical shut-off 78 at least partially in the second channel 74 is arranged and by means of which the flow of the damping fluid through the second channel 74 through is adjustable. As in 10 and 11 shown is the control valve 76 for example, in a control valve insertion hole extending along the rotation part rotation axis R1 43 be used in the body 41, so that the shut-off 78 in the second channel 74 is arranged. As in 11 a control valve shaft extends 80 of the control valve 76 from the shut-off section 78 out through the control valve insertion hole 43 and has a head part 82 on. The control valve insertion hole 43 For example, has a thread that is engaged with a thread formed on the control valve shaft 80 in engagement. The headboard 82 For example, by means of an associated tool through the control valve insertion hole 43 be reachable by the position of the shut-off 78 within the second channel 74 to change and thus the flow of the damping fluid through the second channel 74 through.

As in 10 and 11 shown, the second channel 74 a first section 75a , a second section 75b , a third section 75c and a fourth section 75d exhibit. The first paragraph 75a extends transversely to the rotation part longitudinal axis L and transversely to the rotation part rotation axis R1, opens at its one end in the second chamber portion 45 off and is at the other end with the second section 75b connected. The second section 75b extends along the rotation part rotation axis R1 from the first portion 75b vertically downwards (eg in alignment with the control valve insertion hole) 43 ) and connects the first section 75a with the third and the fourth section 75c and 75d , The shut-off section 78 of the control valve 76 can be at least partially through the first and the second section 75a and 75b extend the flow of damping fluid through the first and second sections 75a and 75b through. The third section 75c extends along the rotation part rotation axis R1 toward the first chamber portion 44 , is at one end with the second section 75b connected and opens at its other end in the first chamber section 44 out. The fourth section 75d extends along the rotation part rotation axis R1 in the direction away from the first chamber portion 44 (eg opposite to the third section 75c ) and leads to an outer surface of the body 41 outward, with the fourth section 75d is closed at the other end (eg by means of a ball, as in 10 shown). The fourth section 75d may be for example for filling or emptying damping fluid into or out of the inner chamber 42 act.

The hydraulic device may also include a third channel 84 in the piston body 50 is formed and the first chamber section 44 and the second chamber portion 45 fluidly interconnected. The third channel 84 is for example in the first piston body part 54 of the piston body 50 along the rotational part longitudinal axis L and at a distance from the first channel 70 (eg in Direction of the rotation part rotation axis R1 above the first channel 70 ) educated. The third channel 84 is not on its position in the piston body 50 limited and may be arranged arbitrarily to the first chamber section 44 and the second chamber portion 45 fluidly connect to each other. A second check valve 86 is in the third channel 84 arranged and arranged so that the damping fluid from the second chamber section 45 through the third channel 84 through into the first chamber section 44 can flow in when a displacement of the piston body 50 in the direction of the biasing force of the disc spring device 60 a pressure of the damping fluid in the second chamber portion 45 exceeds a predetermined pressure, and that upon displacement of the piston body 50 in the direction opposite to the biasing force of the disc spring device 60 a flow of the damping fluid from the first chamber portion 44 through the third channel 84 through into the second chamber section 45 is blocked.

By means of the second check valve 86 can be prevented during a displacement of the piston body 50 in the direction of the biasing force of the disc spring device 60 an excessive pressure in the second chamber portion 45 arises when a displacement of the piston body 50 in the direction of the biasing force of the disc spring device 60 the damping fluid no longer through the second channel 74 through from the second chamber section 45 in the first chamber section 45 can flow. A case in which the damping fluid is no longer through the second channel 74 through from the second chamber section 45 in the first chamber section 45 can flow, for example, in a (eg wanted or faulty) setting of the control valve 76 so that the second channel 74 is completely shut off, or with a blockage of the second channel 74 , eg through into the inner chamber 42 penetrated foreign material, present. Thus, damage to the components of the door fitting structure 10 be prevented due to excessive pressure. The predetermined pressure can be exceeded, for example, when an external force is applied externally to the door leaf and consequently to the rotary part connected to the door leaf, the external force originating, for example, from a person pushing or pulling the door leaf.

The first and second check valves 84 and 86 may be spring loaded ball check valves having a ball and a spring biasing the ball in a valve closing direction, as in 4 to 7 shown. However, other types of check valves may be used in the door fitting structure 10, and the present invention is not limited to ball check valves. For example, the two check valves 84 and 86 also be realized in a single construction.

It should be noted that the door fitting structure 10 according to the present invention does not necessarily have its own hydraulic means for damping the rotational movement of the rotary member 40 relative to the stationary part 20 must have. It can also be provided, for example, that one of the upper and the lower door fitting 3 and 4 a damping device for damping the rotational movement of the rotary part 40 relative to the stationary part 20 and the other of the upper and lower door fittings 3 and 4 the door fitting structure 10 according to the present invention, in which case the door fitting structure 10 According to the present invention may be formed without its own hydraulic device, but may also additionally comprise the hydraulic device described herein. It is to be understood that further such combination possibilities are possible depending on the specific application.

Furthermore, in a previously described door fitting structure 10 according to the present invention, the piston body 50 also with a counter contact element 52a be provided as in 12 to 15 is shown. The mating contact element 52a can in the same way as described above, as the contact element 52 be educated. For example, the mating contact element 52a be a counter-roller, which is rotatable about a to the rotation part rotation axis R1 and the roller rotation axis R2 counter roller rotation axis R3 with the piston body 50 (eg with the first piston body part 54 ) connected is. The counter-roll 52a can, for example, by means of a Gegenrollendrehwelle 53a rotatable with the with the first piston body part 54 of the piston body 50 be connected. The mating contact element 52a is at a distance to and with respect to the rotation part rotation axis R1 relative to the contact element 52 arranged. The mating contact element 52a is so on the piston body 50 arranged that the mating contact element 52a with the cam profile of the contact section 22 (eg with the second cam profile surface 28 at a Drehbwegung from the third rotational position to the first rotational position or with the fourth cam profile surface 34 in a Drehbwegung from the second rotational position to the first rotational position) comes in touching contact, when a rotational movement of the rotary member 40 relative to the stationary part 20 in the first rotational position through the hydraulic device to the piston body 50 in the direction against a spring force of the disc spring device applied counterforce (eg, damping force) at least substantially equal to or greater than that of the disc spring device 60 on the piston body 50 applied spring force is. By means of the contact contact between the Contact element 52a and the cam profile of the contact portion 22 is a force on the piston body 50 in the direction of the biasing force of the disc spring device 60 applied, leaving the piston body in the inner chamber 42 in the direction of the biasing force of the disc spring device 60 is moved.

The piston body 50 of the rotary part 40 can also have a sleeve section 59 having the disc spring device 60 at least partially surrounds the at least one plate spring of the disc spring device 60 respectively. The sleeve section 59 may, for example, in the direction opposite to the biasing force of the disc spring device 60 extend. Like in 4 shown, the sleeve section 59 from the second piston body part 56 from in the direction opposite to the biasing force of the disc spring device 60 extend. The sleeve section 59 has, for example, a sleeve section inner surface, with which an outer circumference of the at least one plate spring of the disc spring device 60 comes into contact.

The rotation part 40 can also be a guide pin 90 that in the inner chamber 42 is arranged and extending through a central opening of the at least one plate spring of the disc spring device 60 extends through the at least one plate spring of the disc spring device 60 respectively. Furthermore, the rotation part 40 a side closure 92 which has a lateral opening of the main body 41 of the rotary part 40 that with the inner chamber 42 is in communication and which is formed, for example, around the rotary part longitudinal axis L around substantially circular, closes. The side closure 92 can with the main body 41 of the rotary part 40 be bolted and a sealing element can between the side closure 92 and the main body 41 are present, around the lateral opening of the main body 41 close tightly. The side closure 92 can a the piston body 50 opposite mating surface for installation of the disc spring device 60 form. The guide pin 90 can be attached to a central section of the side closure 92 to be appropriate. Furthermore, the lateral closure 92 a shutter guide portion 94 having the disc spring device 60 at least partially surrounds the at least one plate spring of the disc spring device 60 respectively. The closure guide portion 94 may, for example, in the direction of the biasing force of the disc spring device 60 extend and may have a guide portion inner surface, with which an outer periphery of the at least one plate spring of the disc spring device 60 comes into contact.

The stationary part 20 may further be one of the rotary part 40 from along the rotary part rotation axis R1 outwardly projecting mounting portion 23 for stationary attachment to a door to the door 2 have adjacent point. The mounting section 23 is for example by means of a corresponding Bodenanbringungsplatte fixed to the ground 7 below the door leaf 2 can be connected, but can also be fixed to the door frame 5 the door 1 be connected. As in 4 and 6 shown is the stationary part 20 eg by means of bearings 32 , For example, needle bearings, rotatable with the rotary member 40 connected. Furthermore, the stationary part 20 as an along the rotation part rotation axis R1 extending, optionally formed as a piece (eg material integral), spindle may be formed, which within the inner chamber 42 arranged contact portion 22 and the above mounting section 23 having.

As in particular from 2 and 3 and 8, 9 and 11 can be seen, the main body 41 of the rotary part 40 Further, a body recess 47 located in an outer surface of the main body 41 is formed and extends on a first side of the outer surface along a rotation part longitudinal axis L extending transversely to the rotation part rotation axis R1, and a support projection 48 coming from the outer surface of the main body 41 protrudes and extends at a second side of the outer surface opposite the first side along the rotation part longitudinal axis. Furthermore, the rotary member may have a mounting plate 49, which in the body recess 47 is used and by means of at least one first fastening means, for example by means of two first fastening means 96 with the base body 41 is connected to hold (eg pinching) of the door leaf 2 between the mounting plate 49 and the supporting projection 48 , The at least one first fastening means 96 can be within the body 41 extend. The door fitting structure 10 may further include a second attachment means 98 to engage in an opening 202 . 302 in the door 2, as in 16 and 17 shown having the mounting plate 49 with the support projection 48 combines. The second attachment 96 can pass through a gap between the mounting plate 49 and the supporting projection 48 extend. Due to the compact design of the door fitting structure 10 It is possible that the outer shape and dimensions of the body to a door fitting assembly cutout 200 . 300 in the door 2 can be optimally adapted. Furthermore, at an already in the door 2 existing door fitting assembly cutout (eg a door fitting assembly cutout with common standard dimensions) 200, 300 this existing cutout due to the compact design of the door fitting structure 10 be used and no new (eg larger or with another shape provided) door fitting assembly cutout 200, 300 in the door leaf 2 be brought in, what a retrofitting of a such door leaf 2 much easier. It should be understood that the door fitting structure of the present invention is not intended to be mounted to the in 16 and 17 door fitting mounting cutouts shown 200 . 300 is limited, but is adaptable and attachable to door fitting assembly cutouts of various sizes and shapes. The in 16 and 17 door fitting mounting cutouts 200, 300 shown, for example, at an upper and / or a lower corner of the door leaf 2 (Corresponding to the position of the upper and / or lower door fitting 3 in 1 ) be formed.

In an example of common dimensions, an in 16 shown door fitting assembly cutout 200 have a shape that is defined by a vertically extending outer edge 201 of the door leaf 2 from in the width direction B of the door leaf 2 extending (eg level) first surface 204 with the length L2 and by a width direction in the width direction B of the door leaf 2 extending arcuate second surface 206 that are on the first surface 204 immediately connects and their from the first surface 204 removed (eg, lower) edge E in the vertical direction V at a distance H1 from the first surface 204 lies as well as from the vertical, outer edge 201 of the door leaf 2 is at a distance with the length L2. Consequently, the first surface lies 204 at a distance H1 from a horizontal outer edge 201b of the door leaf 2 , The in 16 shown door fitting assembly cutout 200 Thus, a length L1, the length of a flat surface of the body 41 between the mounting plate 49 and the supporting projection 48 is located, corresponds, a length L2, which has a length of the underside of the body 41 the door fitting structure 10 corresponds, and a height H1, with a height of the main body 41 between the bottom of the body 41 and the flat surface of the body 41 between the mounting plate 49 and the supporting projection 48 lies, corresponds, has. In other words, the door fitting assembly cutout 200 a maximum length L2 along the longitudinal direction of the door fitting structure 10 and a maximum height H1 along the rotation part rotation axis R1 of the door fitting structure 10 on. For door fitting assembly cutouts 200 , as in 16 shown, with common dimensions, for example, the length L1 may be at least substantially 68mm, the length L2 may be at least substantially 131mm and the height H1 may be at least substantially 36mm.

In another example of common dimensions, an in 17 shown door fitting assembly cutout 300 have a shape that is defined by a vertically extending outer edge 301 of the door leaf 2 from in the width direction B of the door leaf 2 extending (eg level) first surface 304 , one the opening 302 forming (eg round) second surface 306 , which adjoins the first surface 304, and one substantially perpendicular to the first surface 304 extending (eg level) third surface 308 , which adhere to the second surface 306 followed. The vertical, outer edge 301 of the door leaf 2 has a distance L3 to the third surface 308 , and one from the second surface 306 removed (eg lower) edge D of the third surface 308 has a distance H2 from the first surface in the vertical direction V. 304 , Consequently, the first surface lies 304 at a distance H2 from a horizontally extending, outer edge 301b of the door leaf 2 , The in 17 shown door fitting assembly cutout 300 Thus, a length L3 that is equal to a length of the underside of the main body 41 the door fitting structure 10 corresponds, and a height H2, with a height of the main body 41 between the bottom of the body 41 and the flat surface of the body 41 between the mounting plate 49 and the supporting projection 48 lies, corresponds, has. In other words, the door fitting assembly cutout 300 a maximum length L3 along the longitudinal direction of the door fitting structure 10 and a maximum height H2 along the rotational part rotation axis R1 of the door fitting structure 10 on. For door fitting assembly cutouts 300 , as in 17 shown, with common dimensions, for example, the length L3 may have a value of at least substantially 114mm and the height H2 has a value of at least substantially 27mm or, for example, the length L3 has a value of at least substantially 136mm and the height H2 a value of at least essentially 38mm.

Due to the compact design of the door fitting structure 10 According to the present invention, the door fitting structure 10 , in particular their basic body 41 , Such dimensions have to be inserted into the aforementioned door fittings mounting cutouts of common dimensions without these door fitting mounting cut-outs must be modified, so that existing doors can be easily retrofitted. It should be noted that the dashed lines in FIG 16 and 17 are shown only to illustrate the dimensions and indicate no structural parts. The rotation part 40 may further comprise a lower cover (eg, a bottom cap) 100 having a lower opening formed in the underside of the body 41 is formed by means of sealing elements 102 between the lower cover 100 and the body 41 closes fluid-tight. The lower cover 100 can one of the bearings 32 and may further comprise a central opening through which the mounting portion 23 of the stationary part 20 from the rotary part 40 protrudes out, with sealing elements 104 between the lower cover 100 and the mounting section 23 are provided to close the central opening fluid-tight.

Hereinafter, with reference to the figures, in particular 4 to 7 , the operation of a door fitting structure 10 described according to the present invention.

As in 4 and 5 shown is the contact element 52 engaged with the first Indexiermulde 24 and is the rotation part 40 with respect to the stationary part 20 in the first rotational position. The first rotational position corresponds for example to a desired closed position of the rotary part 40 connected door leaf 2 , By means of the engagement between the contact element 52 and the first indexing trough 24 becomes the rotation part 40 with respect to the stationary part 20 held in the first rotational position until a sufficient force on the rotary part 40 from the outside, for example from a door leaf 2 pulling or pushing person, is applied to the contact element 52 from the first indexing trough 24 to solve.

When the rotation part 40 relative to the stationary part 20 is rotated from the first rotational position in the direction of the second rotational position (eg because the door 2 is moved from the closed position), then the contact element 52 from the first indexing trough 24 dissolved and by means of the contact contact with the cam profile of the contact portion 22 guided along the cam profile. In the transition from 5 to 7 the contact element moves 52 along the first cam profile surface 26 of the cam profile. By the movement of the contact element 52 along the cam profile of the contact section 22 becomes the piston body 50 in the inner chamber 42 moved in the direction opposite to the biasing force of the disc spring device 60, wherein the at least one plate spring of the disc spring device 60 (For example, as shown in the figures between the side closure 92 and the second piston body part 56 of the piston body 50 ) is elastically compressed.

By the displacement of the piston body 50 , in particular the displacement of the first piston body part 54 , in the direction opposite to the biasing force of the disc spring device 60 Further, the volume of the second chamber portion 45 is increased and the volume of the first chamber portion 44 reduced so that the pressure of the damping fluid in the second chamber section 45 is reduced and in the first chamber section 44 is enlarged. Due to the resulting pressure difference between the two chamber sections 44 and 45 the damping fluid flows through the first channel 70 and the first check valve 72 passes out of the first chamber portion 44 in the second chamber section 45 one. It is also possible that a certain amount of damping fluid in the displacement of the piston body 50 in the direction opposite to the biasing force of the disc spring device 60 from the first chamber section 44 through the second channel 74 into the second chamber section 45 flows. Furthermore blocked during the displacement of the piston body 50 in the direction opposite to the biasing force of the disc spring device 60 the second check valve 86 a flow of the damping fluid through the second channel 84 therethrough.

The 6 and 7 illustrate a state in which the rotation part 40 relative to the stationary part 20 is rotated counterclockwise from the first rotational position to the second rotational position and the contact element 52 engaged with the second Indexiermulde 25 is. The second rotational position may be a position in which the rotary part 40 counter clockwise by 90 degrees relative to the stationary part 20 was turned (see 5 With 7 ). It should be noted that it acts for illustrative purposes only as if from 5 to 7 the stationary part 20 rotated, whereas actually the rotation part 40 around the stationary part 20 has turned. For example, the second rotational position corresponds to a desired fully open position of the rotational part 40 connected door leaf 2 , If the rotation part 40 relative to the stationary part 20 is rotated counterclockwise beyond the second rotational position can, by means of the above-described second cam surface 28 the further counterclockwise rotation becomes more difficult and eventually blocked and the rotary member 40 is returned to the second rotational position. By means of the engagement between the contact element 52 and the second indexing well 25 becomes the rotation part 40 with respect to the stationary part 20 held in the second rotational position until a sufficient force on the rotary member 40 is applied from the outside to the contact element 52 towards the first indexing trough 24 from the second Indexiermulde 24 to solve.

When the contact element 52 towards the first indexing trough 24 from the second Indexiermulde 24 has been solved, then the spring force of the compressed disc spring device acts 60 on the piston body 50 and pushes the contact element 52 against the cam profile of the contact portion 22 , The piston body 50 will be in the inner chamber 42 moved by means of acting on him spring force of the disc spring device 60, wherein the at least one plate spring of the disc spring device 60 expanded. Further, by means of the contact contact of the contact element 52 and the cam profile of the contact portion 22 the contact element 52 guided along the cam profile and is a on the rotary part 40 produces acting torque, so that the rotation part 40 relative to the stationary part 20 (in 4 to 7 ) is rotated clockwise toward the first rotational position.

By the displacement of the piston body 50 , in particular the displacement of the first piston body part 54 , in the direction of the biasing force of the disc spring device 60 Further, the volume of the first chamber portion 44 increases and the volume of the second chamber section 45 reduces, so that the pressure of the damping fluid in the second chamber section 45 is increased and in the first chamber section 44 is reduced. There is thus a pressure difference between the first chamber section 44 and the second chamber portion 45 generated. In this case, the first check valve blocks 72 a flow of the damping fluid through the first channel 70 therethrough. The damping fluid flows during the displacement of the piston body 50 in the direction of the biasing force of the disc spring device 60 instead through the second channel 74 wherein the damping fluid is an attenuation of the displacement of the piston body 50 and consequently a damping of the rotation of the rotating part 40 relative to the stationary part 20 causes. By means of the second channel 74 arranged control valve 76 the degree of damping can be adjusted.

Consequently, the rotation part becomes 40 is automatically returned to the first rotational position by means of the indexing device and this movement of the rotary part is damped to the first rotational position by the hydraulic device. As a result, a damped closing movement of the door leaf 2 realized in the closed position.

Further, when the displacement of the piston body 50 in the direction of the biasing force of the disc spring device 60 a pressure of the damping fluid in the second chamber portion 45 exceeds a predetermined pressure, then opens the second check valve 86 such that the damping fluid from the second chamber section 45 through the third channel 84 through into the first chamber section 44 can flow in. The second check valve 86 thus also acts as a kind of safety valve to a closing movement of the door leaf 2 even if there should be a case in which the second channel 74 blocked (eg clogged) is.

If the door fitting structure 10 Furthermore, the mating contact element 52a can, if during the rotational movement of the rotary member 40 relative to the stationary part 20 in the direction of the first rotational position through the damping fluid to the piston body 50 applied counterforce at least substantially equal to or greater than one of the disc spring device 60 on the piston body 50 applied spring force is the mating contact element 52a in contact with the cam profile (eg here the fourth cam profile surface 34 ) of the contact section 22 come and by means of this contact contact a force on the piston body 50 exercise to the piston body 50 in the direction of the biasing force of the Tellefedereinrichtung 60 to press. In other words, during the rotational movement of the rotating part 40 relative to the stationary part 20 in the direction of the first rotational position through the damping fluid to the piston body 50 in the direction against the spring force of the disc spring device 60 applied counterforce at least substantially equal to or greater than one of the disc spring device 60 on the piston body 50 be applied spring force (for example, if the rotation part 40 is already near its first rotational position and the disc springs 62 the disc spring device 60 already largely expanded), so that the piston body 50 in the inner chamber 42 initially not further in the direction of the biasing force of the Tellefedereinrichtung 60 shifts and the contact element 52 from the cam profile of the contact section 22 can solve while the rotation part 40 relative to the stationary part 20 continues to rotate in the direction of the first rotational position (eg due to the inertia of the rotating part with 40 connected door leaf 2 ). In this case, then comes the cam profile of the contact section 22 in touching contact with the mating contact element 52a and pushes the piston body 50 in the direction of the biasing force of the Tellefedereinrichtung 60 , The contact contact between the cam profile of the contact section 22 and the mating contact element 52a results in that by the hydraulic means of the rotational movement of the rotary member 40 relative to the stationary part 20 is counteracted damping. By means of the mating contact element 52a For example, the first rotational position can be indexed faster and more reliably because the contact element 52 Reliable with the first Indexiermulde 24 can be engaged. Thus, it can be more effectively prevented that the rotary member rotates beyond the first rotational position.

Although above the movement of the rotating part 40 relative to the stationary part only between the first and the second rotational position (ie between the first and third Indexiermulde 24 and 25 ), it will be understood that the above description also applies analogously to a movement between the first and third rotational positions (ie between the first and third indexing recesses 24 and 30 ) applies.
