Description

The present disclosure relates to a door fitting for mounting with a door leaf and a door comprising a door leaf and a door fitting.

It is known that in lockable door fittings with two opposing handles, an actuating element is attached to a first handle, by means of which the door can be locked. The door, or more precisely the lock unit of the door, can then no longer be opened with the second handle. Such lockable door fittings are regularly used, for example, in bathroom doors or hotel room doors. The known lockable door fittings, however, have various disadvantages, which are addressed in the context of the present disclosure.

A disadvantage of the previously known lockable door fittings is that their handles and/or rosettes, due to the integrated functionality, regularly require significantly more installation space than door fittings without a locking function. This can limit or even prevent the installation of these door fittings with door leaves. In addition, such door fittings and in particular their handles are considered to be visually and/or perceived as not very appealing to the touch. Accordingly, one aim of the present disclosure is to provide a door fitting that has a compact design.

A further disadvantage of the previously known lockable door fittings is that they sometimes have security deficiencies. For example, because the lock can easily be released unintentionally, or a relatively small amount of force is sufficient to release the second handle despite the intended locking. A further aim of the present disclosure is therefore to provide a door fitting that ensures a higher level of security.

In summary, it is therefore an object of the present disclosure to provide a door fitting and a corresponding door which addresses the aforementioned disadvantages.

This object is achieved by a door fitting according to independent claim 1. Further aspects of the present disclosure are described in the dependent claims.

In particular, the object is achieved by a door fitting for mounting with a door leaf. The door fitting comprises a first handle and a shaft element for forming an operative connection with a lock unit introduced into the door leaf. The shaft element is connected to the first handle in a rotationally fixed manner.

A handle in the sense of the present disclosure preferably comprises a grip. In particular, a handle can have a handle made up of a variety of different types of handles. Examples of different types of handles are conventional door handles, knob handles and push handles. Furthermore, a handle can be designed in several parts. For example, a handle can have an outer part and an inner part, wherein the inner part is arranged at least partially within the outer part. The outer part can be configured to be gripped by a user. The inner part can serve to realize a rotationally fixed connection of the handle to the shaft element.

The shaft element is preferably rod-shaped. In addition, the shaft element can have a round profile, a square profile, a hexagonal profile and/or an octagonal profile. Furthermore, the shaft element can be at least partially hollow, e.g. as a hollow cylinder.

The door fitting further comprises a locking device which is designed to prevent rotation of the shaft element and a switching element which is rotatable relative to the first handle between a first rotation position and a second rotation position and which actuates the locking device. In the first rotation position of the switching element, rotation of the shaft element is permitted by the locking device and in the second rotation position of the switching element, rotation of the shaft element is prevented by the locking device.

A rotation of the shaft element is understood to mean in particular a rotation of the shaft element relative to the locking device, relative to the first handle, relative to a rosette of the door fitting, relative to the door and/or relative to the lock unit.

The locking device can be configured to prevent rotation of the shaft element directly and/or indirectly. For example, a configuration is possible in which the shaft element itself remains rotatable in the locked state, but is separated from an associated handle in such a way that no rotation can be transmitted from this handle to the shaft element, so that rotation of the shaft element is prevented in this way. Further details on possible locking devices are described below.

The switching element can be made up of one or more parts and can include bearing elements that ensure rotation.

The door fitting also includes an actuating slide which is connected to the first handle and can be moved relative to the first handle. The actuating slide and the switching element engage with one another in such a way that a displacement of the actuating slide leads to a rotation of the switching element from the first rotation position to the second rotation position and back.

A first position of the actuating slide can be assigned to the first rotational position of the switching element and a second position of the actuating slide can be assigned to the second rotational position of the switching element. The actuating slide can comprise several individual parts. In particular, the actuating slide can be designed in two parts. Furthermore, the actuating slide can preferably be displaced in a direction that is essentially parallel to the axis of the switching element. However, it is understood that the actuating slide does not necessarily have to be configured in such a way that it can be displaced linearly.

The door fitting as described here is advantageous in several respects. Three advantages are described in more detail below.

One advantage is that this door fitting enables the realization of compact designs. For example, the operating slide and the switching element can be arranged in the first handle and engage with each other in such a way that the required installation space is reduced.

A further advantage is that the engagement of the actuating slide with the switching element can be used to adjust how hard or easy the switching element is to move from the second rotation position can be moved out. This makes it possible to use this door fitting to prevent the lock from being accidentally released. This door fitting can therefore provide a higher level of security.

It is understood that the advantages described may also apply to the following embodiments in various forms.

The operating slide can be arranged at least partially in the first handle and preferably guided. This makes it possible to ensure that the operating slide is reliably held in the first handle. In addition, particularly compact designs of the door fitting can be realized.

Furthermore, the switching element can be rotatably mounted at least partially in the first handle, in particular in a neck section of the first handle. By rotatably mounting the switching element in the first handle, the door fitting can be made even more compact. The switching element is preferably mounted in a sliding manner. This means that rolling bearings that require more space, such as ball bearings, can be dispensed with.

The first handle preferably has a neck section, with the operating slide and the switching element being arranged at least partially in the neck section. This arrangement allows the operating slide to be located behind the handle from the user's perspective when the door fitting is mounted on the door leaf, thus achieving a visual improvement. In addition, an arrangement of the operating slide can be achieved in this way which prevents unintentional unlocking. Furthermore, the door fitting can be designed to be particularly compact. The neck section preferably extends essentially parallel to the shaft element.

The actuating slide can have a guide projection and the switching element can have a guide track, the guide projection and the guide track engaging with each other. The engagement of the guide projection and the guide track allows the switching element to be moved precisely between the first and second rotational positions. Furthermore, a gear ratio can be specifically set using the design of the guide track, such as its slope. This allows an adapted actuating feel of the actuating slide to be realized and/or an unintentional release of the lock to be prevented. The guide projection can be pin-shaped. The guide track is preferably a groove.

The switching element can have a cylindrical shape, in particular a circular cylindrical shape, and the guide track can be incorporated into the outer surface of the cylindrical shape. A circular cylindrical shape is advantageous in that a rotatable mounting of the switching element is particularly easy to implement. In addition, by incorporating the guide track into the outer surface, a space-saving design can be achieved while at the same time requiring few components.

The switching element is preferably rotatable about an axis that is substantially parallel to the shaft element, wherein the axis is further preferably the axis of rotation of the shaft element. This arrangement allows a compact and space-saving arrangement of the switching element, for example within the neck section of the first handle.

Preferably, between the first rotation position and the second rotation position there is an angle of rotation in the range of 70° to 190°, preferably from 80° to 100° and most preferably from 85° to 95°. These angles of rotation have proven to be advantageous in that transmission ratios between the switching element and the actuating slide which result in suitable forces for operating the operating slide. In particular, forces which give the user the feeling of a reliable locking mechanism and/or prevent unintentional unlocking.

Furthermore, the door fitting preferably comprises a second handle, wherein the locking device is arranged at least partially and preferably completely in the second handle. For example, the second handle is connected to the shaft element in a rotationally fixed manner. By arranging the locking device at least partially or completely in the second handle, it is possible to realize more compact designs than in cases in which the locking device is arranged in the first handle. In detail, the installation space requirement is divided between the two handles, so that a space-intensive first handle is avoided.

Preferably, an operative connection between the switching element and the locking device is realized by an elongated connecting element, wherein the elongated connecting element extends axially through the shaft element. This design means that no additional hole is required in the door leaf to connect the switching element to the locking device. This means that the door fitting can be mounted on standard door leaves. On the other hand, the elongated connecting element is protected and/or guided within the shaft element. Furthermore, the door fitting is kept compact in this way. The elongated connecting element is preferably rod-shaped.

The second handle can have an opening through which the elongated connecting element and/or the eccentric element can be rotated. The opening enables the second handle to, for example, carry out an emergency unlocking of the door fitting. Preferably, the elongated connecting element can be rotated directly or indirectly through the opening using a coin.

In one embodiment, a locking cylinder is arranged in the second handle, which is arranged in the opening and/or can be operated through the opening, for example by means of a key. The locking cylinder engages in the eccentric element and/or the connecting element, in particular in a rotationally fixed manner. In this way, the door or the door fitting can also be locked from the side of the second handle.

The locking device preferably comprises an eccentric element and at least one blocking element, wherein the eccentric element is connected to the switching element in a rotationally fixed manner and wherein the locking device is designed such that the blocking element is radially displaced relative to the shaft element by rotation of the eccentric element, in particular wherein in the second rotational position compared to the first rotational position the blocking element is offset radially outwards relative to the shaft element. The eccentric element can be a substantially cylindrical element, in particular a circular cylindrical element, wherein a contact surface is formed in the outer surface of the cylindrical element. The contact surface can be configured such that when the eccentric element rotates from the first to the second rotational position the blocking element is pushed radially outwards from the contact surface relative to the shaft element. The locking device preferably comprises at least two blocking elements. This allows redundant operation of the locking device and thus greater safety.

The door fitting can further comprise a rosette for fastening to the door leaf, wherein the blocking element in the second rotation position is in engagement with the second handle and the rosette and blocks rotation of the second handle to the rosette. The engagement of the blocking element with the second handle and the rosette enables reliable locking and increased security. In particular, torsion is prevented from being introduced into the shaft element. The The rosette can be designed such that, in the assembled state, it is arranged at least partially within the door leaf and/or the second handle. In the first rotation position, the blocking element is preferably arranged such that it is arranged in the passive handle and does not engage with the rosette.

The blocking element is preferably cylindrical, in particular circular-cylindrical. This shape allows the blocking element to be easily eccentricated and also provides stable guidance. However, a spherical blocking element is also conceivable.

The locking device of a further embodiment preferably comprises a first ramp element which is connected in a rotationally fixed manner to the switching element, and a coupling device which is connected in a rotationally fixed manner to the second handle, wherein the coupling device is axially displaceable relative to the shaft element by rotating the first ramp element, wherein the coupling device is connected in a rotationally fixed manner to the shaft element in the first rotational position and wherein the rotationally fixed connection of the coupling device to the shaft element is released in the second rotational position. This configuration of the locking device can help to enable a higher level of security. In particular, after the rotationally fixed connection of the coupling device to the shaft element is released in the second rotational position, even a high force acting on the first handle cannot lead to rotation of the shaft element. Furthermore, this locking device allows for compact designs. Particularly since a rosette does not necessarily have to be provided to contribute to locking.

The coupling device preferably comprises a second ramp element which cooperates with the first ramp element such that a rotation of the first ramp element leads to an axial displacement of the second ramp element and a coupling element which is connected by means of the second Ramp element is axially displaceable and is designed such that it is brought into a rotationally fixed connection with the shaft element and/or released from this by axial displacement. The first ramp element and/or the second ramp element can be a cylindrical element. In this case, a ramp surface is preferably provided on a base surface of the first cylindrical ramp element and the second cylindrical ramp element, which is inclined relative to the axis of the shaft element. These ramp surfaces can be in contact with one another in the assembled state and slide on one another when the locking device is actuated. Furthermore, the first ramp element and/or the second ramp element is preferably mounted within the second handle.

In particular, the object described in the introduction is also achieved by a door comprising a door leaf and a door fitting as described herein. The features and advantages described for the door fitting apply equally to the door and vice versa.

an enlarged view of the locking cylinder of the door fitting according to Figure 10 .

The Figures 1 to 5 show a first embodiment of a door fitting 1 according to the present invention. In addition, Fig.1 a door 100 according to the invention is shown. The door 100 comprises a schematically shown door leaf 110, a likewise schematically shown lock unit 120 and the door fitting 1.

As in Fig.1 As shown, the door fitting 1 comprises a first handle 10, a second handle 60, a shaft element 20 and a rosette 80. The rosette 80 is connected to the door leaf 110 in a rotationally fixed manner by means of two elongated connecting elements which extend through the door leaf 110.

The shaft element 20 is designed in a manner known per se to form an operative connection with the lock unit 120 introduced into the door leaf 110. The shaft element 20 is connected in a rotationally fixed manner to an inner part 15 of the first handle 10 and in a rotationally fixed manner to an inner part 65 of the second Handle 60. When the door fitting 1 is in the unlocked state, actuation of one of the handles 10, 60 thus leads to rotation of the shaft element 20, whereby the lock unit is actuated and opened in a manner known per se.

As in Fig.2 shown, the door fitting 1 further comprises a switching element 40 and an actuating slide 50. The switching element 40 and the actuating slide 50 are each arranged in a neck section 11 of the first handle 10, wherein a part of the actuating slide 50 protrudes outwards through the first handle 10 and can accordingly be actuated manually (see also Fig.5 ).

The switching element 40, which has a circular cylindrical shape, is rotatably mounted in the neck section 11. The switching element 40 is rotatable relative to the first handle 10 between a first rotational position and a second rotational position about the rotational axis of the shaft element.

The switching element 40 has a guide track 41. The guide track 41 is a groove which is introduced into the outer surface 42 of the circular cylindrical switching element 40.

The two-part actuating slide 50 can be moved within the first handle 10. The actuating slide 50 and the switching element 40 engage with each other in such a way that a displacement of the actuating slide 50 leads to a rotation of the switching element 40 from the first rotational position to the second rotational position and back.

In detail, the actuating slide 50 has a guide projection 51 in the form of a pin which engages with the guide track 41

Furthermore, as in the Figures 3 to 5 As shown, the door fitting 1 comprises a locking device 30 which is designed to prevent rotation of the shaft element 20. The locking device 30 is completely in the second handle 60 (see also Fig. 2 ) and is actuated by the switching element 40.

The locking device 30 is also arranged within a portion of the rosette 80 which extends into the second handle 60.

Specifically, a rotationally fixed operative connection between the switching element 40 and the locking device 30 is realized by an elongated connecting element 70 which extends axially from the switching element 40 through the shaft element 20 to the locking device 30.

A rotation of the switching element 40 is transmitted to the locking device 30 via the connecting element 70.

In the Fig. 3 and 4 the locking device 30 is shown enlarged. The locking device 30 comprises an eccentric element 31 and a blocking element 32.

In the assembled state, the eccentric element 31 is connected in a rotationally fixed manner to the switching element 40 via the elongated connecting element 70.

The eccentric element 31 has at least one ramp surface for the blocking element 32 on its peripheral surface. In particular, as many ramp surfaces as blocking elements are provided.

The ramp surface has a slope along the circumferential direction. The radius of the eccentric element 31 thus varies along the circumferential direction.

The blocking element 32 rests on the associated ramp surface of the eccentric element 31 and lies in a first opening 66 in the inner part 65 of the second handle 60. The blocking element 32 is radially displaceable by rotating the eccentric element 31 relative to the shaft element 20.

As in Fig.5 As shown, in the second rotational position, compared to the first rotational position, the blocking element 32 is offset radially outward relative to the shaft element 20. The cylindrical blocking element 32 is then in engagement with the second handle 60 and the rosette 80, so that rotation of the second handle 60 relative to the rosette 80 is blocked.

In detail, according to the Fig.4 and 5 , when the eccentric element 31 rotates from the first rotational position to the second rotational position, the blocking element 32 is partially pushed outwards through the first opening 66 in the inner part 65 of the second handle 60 due to the slope of the ramp surfaces and then engages in a first locking groove 81 in the rosette 80, so that the handle 60 is locked to the rosette 80.

Further in Fig.4 It can be seen that the inner part 65 has a second opening 67 and the rosette 80 has a second locking groove 82. A second blocking element can therefore be arranged in the concealed area of the eccentric element 31.

In this way, in the first rotational position of the switching element 40, rotation of the shaft element 20 is released by the locking device 30 and in the second rotational position of the switching element 40, rotation of the shaft element 20 is prevented by the locking device 30.

To lock the door 100 from the side of the first handle 10, the actuating slide is moved linearly. This linear movement is converted by the switching element 40 into a rotary movement, which transfers the switching element 40 from the first rotary position to the second rotary position.

At the same time, the connecting element 70 rotates the eccentric element 31, whereby the blocking element 32 is moved radially outward and the second handle 60 is locked relative to the rosette 80.

A rotation of the shaft element 20 and thus an actuation of the lock unit 120 is then not possible, the door 100 is locked.

As further stated in Fig.5 shown, the second handle 60 has an opening 61 for emergency release, through which the elongated connecting element 70 (in Fig.5 not shown). A bolt-shaped element is located in the opening 61 and is connected to the connecting element 70 in a rotationally fixed manner. The bolt-shaped element can be rotated using an appropriate tool, such as a coin. This provides an emergency release function that can be operated using everyday objects.

The Figures 6 to 9 show a second embodiment of the door fitting 1, which essentially corresponds to the first embodiment. In the following, therefore, only the differences are discussed and identical and functionally identical parts are provided with the same reference numerals.

As in the Fig.6 and 7 shown, one difference is that the actuating slide 50 of the second embodiment is formed in one piece.

Furthermore, the door fitting 1 of the second embodiment differs from that of the first embodiment in particular in the design of the locking device 30. In detail, a difference between the embodiments lies in how, in the second rotational position of the switching element 40, rotation of the shaft element 20 is prevented by the locking device 30.

In the first embodiment, as already described, the shaft element 20 is indirectly blocked and cannot be rotated by the first handle 10. In the second embodiment, the shaft element is not blocked and remains rotatable by the first handle. However, rotation of the shaft element 20 is prevented by the locking device 30 prevents the second handle 60 from being decoupled from the shaft element 20 and prevents the second handle 60 from initiating rotation into the shaft element 20.

Fig. 8 and Fig. 9 show the locking device 30 of the second embodiment in detail. The locking device 30 comprises a first ramp element 34 which, in the assembled state, is connected in a rotationally fixed manner to the switching element 40 via the elongated connecting element 70 and is fixed in the axial direction in the second handle 60 at least in the direction away from the door 100.

Furthermore, the locking device 30 comprises a coupling device 35, which is connected to the second handle 60 in a rotationally fixed manner, and a spring 38.

The spring 38 is supported on an inner part of the second handle 65 and applies an axial force to the coupling device 35 away from the door 100. It is also conceivable that the spring 38 is supported on the rosette.

The coupling device 35 is arranged in the axial direction between the first ramp element 34 and the spring 38. The connecting element 70 therefore extends through the spring 38 and the coupling device 35.

The shaft element 20 extends through the spring and partially through the coupling device 35. The shaft element 20 may have a fastening element 21 at its end which has a non-round outer contour.

The coupling device 35 has a second ramp element 36 and a coupling element 37, both of which are axially displaceable by rotation of the first ramp element 34 relative to the shaft element 20.

The second ramp element 36 has axial projections, in particular ramps, on its side facing the first ramp element 34.

These engage in ramps of the first ramp element 34 in such a way that a rotation of the first ramp element 34 relative to the second ramp element 36 leads to an axial movement of the second ramp element 36 against the restoring force of the spring 38. The movement of the second ramp element 36 also causes the coupling element 37 to be axially displaced.

The second ramp element 36 and the coupling element 37 are partially hollow and have an inner contour.

The inner contour of the coupling element 37 corresponds to the outer contour of the fastening element 21 and the inner contour of the second ramp element 36 is larger than the outer contour of the fastening element 21.

Depending on the axial position of the coupling device 35, the fastening element 21 is located within the coupling element 37 or within the second ramp element 36.

If the fastening element 21 is located within the coupling element 37, a rotationally fixed connection between these parts is achieved due to the corresponding inner and outer contours of the coupling element 37 and fastening element 21. This in turn leads to a rotationally fixed connection between the second handle 60 and the shaft element 20. In this state, the lock unit 120 can be actuated and the door 100 can be opened by means of the second handle 60.

If the fastening element 21 is located within the second ramp element 36, the fastening element 21 can be freely rotated within the second ramp element 36 due to the larger inner contour of the second ramp element 36. There is therefore no rotationally fixed connection of these parts and thus the second handle 60 can be rotated relative to the shaft element 20. In this state, the lock unit 120 cannot be operated and the door 100 cannot be opened by means of the second handle 60. The door 100 is therefore locked.

The position of the fastening element 21 relative to the coupling device 35, i.e. to the second ramp element 36 and the coupling element 37, is determined by the axial position of the coupling device 35.

As described, the axial position of the coupling device 35 depends on the rotational position of the first ramp element 34.

Thus, actuation of the actuating slide 50 leads to a rotation of the switching element 40, the connecting element 70 and finally the first ramp element 34. By rotating the first ramp element 34, the coupling device 35 is axially displaced and thus a rotationally fixed connection between the second handle 60 and the shaft element 20 is created or released.

The coupling device 35 is connected in the first rotational position in a rotationally fixed manner to the shaft element 20, as shown in the Figures 7 and 8 In the second rotational position, the rotationally fixed connection of the coupling device 35 with the shaft element 20 is released.

In the second rotational position, i.e. when the second ramp element 36 is rotated by 90° relative to the first ramp element 34 (with respect to Figs. 7 and 8 ), the coupling element 37 is displaced in the direction of the first handle 10, so that the rotationally fixed connection with the fastening element 21 of the shaft element 20 is released. The spring 38 ensures that the coupling device 35 is reset when the switching element 40 is rotated back from the second rotation position to the first rotation position.

This locking device 30 enables an extremely compact design of the door fitting 1.

Figure 10 shows a third embodiment of the door fitting 1 in an exploded view, wherein the second handle is not shown.

The door fitting 1 of the third embodiment differs from the door fitting 1 of the first embodiment in that the door 100 or the door fitting 1 can be locked from the side of the second handle 60.

For this purpose, a locking cylinder 90 is arranged in the opening 61 of the second handle 60.

The locking cylinder 90 is in Figure 11 shown enlarged and has a housing 92 and a locking lever 94.

A locking mechanism is arranged in the housing 92 and the housing 92 has a slot for inserting a key on one end face, which extends, for example, through the opening 61 or is arranged in alignment therewith.

The locking lever 94 is arranged on the opposite end of the housing 92.

The locking lever 94 engages in the eccentric element 31, in particular in a rotationally fixed manner. For example, the locking lever 94 engages from the front side of the eccentric element 31, which is opposite the connecting element 70.

To lock, a suitable key is inserted through the slot in the locking cylinder 90. Turning the key activates the locking mechanism, which rotates the locking lever 94, for example by 90°.

By rotating the locking lever 94, the eccentric element 31 is also rotated so that - as described for the first embodiment - rotation of the second handle 60 relative to the rosette 80 is blocked. The door 100 is now locked.

For example, the door 100 can be unlocked by the locking cylinder 90 even if the door 100 or the door fitting 1 has been locked by means of the actuating slide 50 from the side of the first handle 10.

It is conceivable that the locking lever 94 engages in the connecting element 70 for actuation, in particular in a rotationally fixed manner.

It is also conceivable that the door fitting 100 of the second embodiment is equipped with a locking cylinder 90 in the same way.
