Description

The present invention relates to a fitting arrangement with a first and a second fitting element for arrangement on opposite sides of a door leaf or window sash, wherein the first fitting element a first handle and the second fitting element is associated with a second handle and the first and second handle by means of an actuating pin with each other are connected, through which a case of a lock is actuated upon actuation of the handle in a first direction.

Fitting arrangements of this type are known in principle and are used in a variety of different variants for opening and closing windows and doors. The fitting elements are used to store the actuating pin and at the same time to create a pleasing cover of the bearing and the actuating pin.

If a door in the closed state is additionally lockable, a lock with a locking mechanism is usually used, from which by means of a key or a permanently installed actuating element, a bolt can be extended, which locks the door in the closed state.

Furthermore, it is known to use, instead of a key, the handles attached to the door or to the window to lock the door or the window. For example, it is known a handle To use the door, which opens the door downwards, to lock the door by moving it upwards. By the upward movement of the handle either a bolt can be extended or it can be a lock latch blocked so that the door can not be opened.

In order to realize such a locking by means of handling, a complex adaptation of the lock mechanism is necessary such that the upward movement of the handles leads to a lock. Alternatively, an additional mechanism in the door leaf or the window sash must be arranged, which prevents actuation of the latch in the locked state.

Known devices, which allow a locking of a door by a movement of the handle, are therefore complicated to perform and thus expensive. In addition, retrofitting such devices is usually not possible.

It is an object underlying the invention to provide a fitting arrangement which makes it possible to easily lock windows and doors by a movement of a handle. Furthermore, the fitting arrangement should be easy to retrofit existing windows and doors.

The object is achieved by a fitting arrangement according to claim 1 and in particular by the fact that a transmission element extends from the first to the second fitting element, through which in an operation of the first handle in the second direction opposite direction provided in the second fitting element Locking means are movable to a blocking position to block a movement of the second handle.

According to the invention, no specially adapted lock mechanism is required for locking. Instead, locking means are provided in the second fitting element, which prevent a movement of the second handle in its blocking position. The locking means can be brought into the blocking position by an actuation of the first handle in a direction which is opposite to the direction for actuating the latch.

By saving a additionally to be integrated into the door panel mechanism and the fact that no special lock mechanism must be provided, the fitting arrangement according to the invention is simple and therefore inexpensive to produce. In addition, the locking means are integrated into the one fitting element, i. there is no need to provide additional fitting elements and / or lock openings for the locking means. Many doors and windows that have normal standard locks can therefore be retrofitted by replacing the fitting elements in a simple manner with the fitting arrangement according to the invention.

The fitting arrangement according to the invention, which can be locked only by the first handle, is particularly suitable for use in doors with lower requirements for locking security, such as bathroom or toilet doors and doors of living or office space, where a lock only from one Side, namely from "inside" is necessary. If, for example, a toilet door is to be locked, the door is closed and then the inner first handle is moved upwards. The movement of the first handle after above is transmitted by means of the transmission element to the locking means, whereupon the locking means block the second handle, which is located outside the toilet. The second handle can now no longer be pushed down to open the toilet door. The toilet door is thus locked.

Advantageous embodiments of the invention are set forth in the subclaims, the drawings and the description.

According to one embodiment, the transmission element is coupled by means of a gear transmission with the first handle. The use of a gear transmission is advantageous in that a rotational movement of the first handle can be particularly easily received and transmitted by gears.

Preferably, the transmission element comprises a shaft which is non-rotatably connected to a first gear, which is arranged in the first fitting element, and a second gear, which is arranged in the second fitting element. The rotational movement of the first handle is converted into a rotational movement of the first gear in the first fitting element. By the rotatably connected to the first gear shaft, the rotational movement is transmitted through the door leaf to the second fitting element and thus to the second gear. In the second fitting element, the locking means are moved by the rotation of the second gear in the blocking position. In this way, the locking means are actuated by a rotational movement of the first handle.

According to a further embodiment, a first bearing ring is arranged in the first fitting element, which has a toothing, the by a movement of the first handle in the second direction is engageable with the first gear and causes a rotation of the first gear. The toothing is arranged such that only a movement of the first handle from a rest position in the second direction, for example, upwards, the first gear and thus actuates the locking means. If the first handle is moved out of the rest position in the first direction, for example downwards, then the teeth of the first bearing ring do not engage in the first toothed wheel. A lock is therefore not possible by moving down.

In order to achieve the required rotation of the transmission element for locking, a third gear between the teeth of the first bearing ring and the first gear can be connected. The third gear may be formed identical to the first gear.

According to a particularly advantageous embodiment, the locking means comprise a rack and a second bearing ring of the second fitting element. Preferably, the second bearing ring on its outer side a flattening or an extension with a straight edge, which is oriented in a rest position of the second handle parallel to the rack. The rack may have a toothing that engages with the second gear. On a toothing opposite side, the rack preferably comprises a flat surface portion. By a rotation of the second gear, the rack is advantageously displaced so that the flat surface portion is brought into engagement with the flattening or the extension of the second bearing ring, whereby a rotational movement of the bearing ring and thus blocks a rotation coupled to the second bearing ring second handle becomes.

Alternatively, the flattening or extension on the second bearing ring can also be omitted if the rack locks the second bearing ring by clamping.

According to a further embodiment, the rack comprises a trough portion and a locking portion. The locking portion is preferably formed by the already mentioned planar surface portion, whereas the trough portion may be formed for example by a part-circular recess of the rack, whose radius is advantageously adapted to the outer radius of the second bearing ring. Is the trough portion in the unlocked state in the region of the second bearing ring, a rotational movement of the bearing ring and thus the second handle is possible. If, however, the rack is moved to lock the fitting assembly and the locking portion brought into contact with the second bearing ring, the second bearing ring and the second handle are blocked.

According to a preferred embodiment, the rack comprises a display element which signals that the fitting arrangement is locked. Especially in bathroom and toilet doors, it is desirable that it is recognizable from the outside, whether the bathroom or toilet is occupied. By providing the display element on the rack, the already required movement of the rack is also utilized to indicate a lock and thus a use of the bathroom or the toilet.

For example, the rack to display the lock, in particular laterally be pushed out of the second fitting element, so that the display element is only visible when the fitting assembly is locked. For example, to a red-colored part the rack are pushed out of the second fitting element.

Alternatively or additionally, the first and / or the second bearing ring can be provided with a display element which signals that the fitting arrangement is locked. In the locked state, such a display element can be brought by the first and second bearing ring in the region of a viewing window of the fitting assembly to make the display element visible. By arranging display elements on both the first and second bearing rings, the locked state on both sides of the fitting assembly, i. both on the inside of the door and on the outside of the door.

The first and / or the second bearing ring can, for example, be rotatably connected to a display ring to which the display element is attached. In principle, the display element can also be attached to an independent display ring, which in particular can be rotated independently of a bearing ring.

According to an advantageous embodiment, the actuating pin extends through the first bearing ring, wherein the bearing ring has inwardly projecting cams, which define contact surfaces and free-wheeling areas for the actuating pin.

More preferably, the actuating pin comprises a rotatably connected to the first handle first pin portion and a rotatably connected to the second handle second pin portion, wherein the first and the second pin portion against each other are rotatable. This contributes to a movement of the first bearing ring in the second direction, ie a locking of the fitting assembly, only by the first handle and not by the second handle can be effected.

Preferably, the second pin portion extends into the first bearing ring, so that it can be brought into engagement with the contact surfaces of the cams. The cams and the freewheel areas of the first bearing ring are preferably designed such that a movement of the first handle in the second direction leads to a rotational movement of the first bearing ring and thus to a locking of the fitting arrangement, the rotational movement of the first bearing ring in the second direction due to However, freewheeling areas is not transmitted to the second pin portion, since the second pin portion is not engaged with the contact surfaces of the cam in this case. The second pin portion thus remains in its rest position during the locking operation.

If the locking of the fitting assembly to be released again, the first handle is moved in the first direction and the blockage of the second bearing ring by turning back the first gear again released. During this, the second pin section again sweeps over the freewheel areas of the first bearing ring, without turning, until the contact surfaces of the first bearing ring again come to rest against the second pin section.

If the door is not only unlocked but also opened, the first handle is rotated further in the first direction. Since the second pin portion is now engaged with the abutment surfaces of the cams of the first bearing ring, the rotational movement of the first handle is transmitted via the first bearing ring to the second pin portion, whereby the latch of the lock is retracted so that the door can be opened. It is understood that the door in the unlocked state by a can open corresponding actuation of the second handle, since it is rotatably connected to the second pin portion.

Preferably, the first handle is non-rotatably connected to the first bearing ring of the first fitting element and the second handle rotatably connected to the second bearing ring of the second fitting element. Thus, if the second bearing ring blocked by the rack, so can not twist the second handle and thereby the second pin section and not pull back the latch.

This in Fig. 1 shown first fitting element 10 is provided for attachment to a door and formed in the form of a circular Türdrückerrosette. It should be noted, however, that the first fitting element 10 may in principle also have other suitable round or angular shapes and may be formed, for example, as a square rosette.

The first fitting element 10 comprises a first base body 12, which is annular and carries in its interior a first bearing ring 14. The first bearing ring 14 is rotatably mounted relative to the first base body 12 and in Fig. 4 shown in more detail.

Through the first bearing ring 14 passes through an actuating pin 15, in the present embodiment, a square pin, the first and second handles, not shown, for example, door handles, connects to each other. The actuating pin 15 is divided into two pin portions, which are mutually rotatable, but firmly connected to one another in an axial direction defined by the actuating pin.

A not shown first pin portion of the actuating pin 15, to which the first handle is rotatably attached, extends exclusively within the first fitting member 10, while the second pin portion 16 of the actuating pin 15 from the second handle through the second fitting member 36 and through the door extends at least partially into the first bearing ring 14 ( Fig. 4 ). The second pin portion 16 is rotatably connected to the second handle.

The first bearing ring 14 has on its inner circumferential surface two mutually opposite projections 17 which engage in a slot of the first handle to rotatably couple the first bearing ring 14 and the first handle by positive engagement with each other.

In the Fig. 4 Arrows illustrated define a first direction 18 in which the first handle is to be moved to open the door. By actuating the first handle in an opposite, second direction 20, the door can be locked.

The first bearing ring 14 comprises on its inner circumferential surface cams 22, which are engageable with the second pin portion 16 depending on the direction of rotation of the first bearing ring 14 in or disengaged.

In the in Fig. 4 shown rest position of the handle and the first bearing ring 14 are the cam 22 with the second pin portion 16 in engagement such that actuation of the first handle in the first direction 18 by corresponding rotation of the bearing ring 14 to an immediate rotation of the actuating pin 15, in particular the second Pin section 16, clockwise leads. This rotation of the second pin portion 16 causes the operation of a latch, so that an opening of the door is possible.

If the first handle starting from the in Fig. 4 On the other hand, when the rest position shown moves in the second direction 20, the first bearing ring 14 rotates counterclockwise, disengaging the cams 22 and the second pin portion 16, and the first bearing ring 14 makes a rotation relative to the second pin portion 16 which the second pin portion 16 between the cam 22 trained freewheeling regions 24 passes. The second pin portion 16 experiences no torque and thus remains in its rest position.

In a portion of an outer peripheral surface of the first bearing ring 14, a toothing 26 is provided, which by the rotation of the first bearing ring 14 of the in Fig. 1 and Fig. 4 shown rest position in the second direction 20 with a rotatably mounted on the first base body 12 third gear 28 (FIG. Fig. 1 ) is engaged and this set in rotation. The third gear 28 is toothed with a likewise rotatably mounted on the base member 12 first gear 30, which sits on a shaft 32.

The rotational movement of the first gear 30 is transmitted via the shaft 32 through the door to a second gear 34, which is arranged in a second fitting element 36, which in Fig. 2 is shown. The second fitting element 36, like the first fitting element 10, is designed in the form of a circular door handle escutcheon and comprises an annular second base body 48, in which a second bearing ring 46 is rotatably mounted. In this case too, the second fitting element 36 can in principle also have other suitable round or angular shapes and, for example, can be designed as a square rosette.

The second gear 34 is toothed with a rack 38 which is mounted tangentially to the second bearing ring 46 slidably mounted on the second base body 48 and guided by two guide projections 39 of the second body 48.

The rack 38 has on its side facing the second bearing ring 46 a recess 42 into which the second bearing ring 46 can dip in the unlocked state of the fitting assembly and which thereby allows a rotation of the second bearing ring 46.

Adjacent to the trough 42, the rack 38 has a flat surface portion serving as a locking portion 40. The locking portion 40 is engageable with a flattening 44 of the second bearing ring 46 to block a rotation of the second bearing ring 46. The flattening 44 of the second bearing ring 46 is arranged such that it runs in a rest position of the second handle parallel to the locking portion 40 of the rack 38, so that a lock can therefore only take place when the second handle is in its rest position.

By the movement of the first handle in the second direction 20 of the Verrieglungsabschnitt 40 is brought by displacement of the rack 38 with the flattening 44, whereby rotation of the second bearing ring 46 and thus the second handle and the second pin portion 16 of the actuating pin 15 is blocked , In this locked state, therefore, the door can not be opened by means of the second handle. At this point it should be mentioned that the door can not be locked by the second handle, because a rotation of the second handle on the one hand, the flattening 44 of the second bearing ring 46 move and on the other hand would not lead to the required shift of the rack 38.

An unlocking of the door is only possible by a movement of the first handle in the first direction 18 by the rack 38 by reverse movement of the teeth 26 of the first bearing ring 14 and corresponding rotation of the gears 28, 30, 34 and the shaft 32 back into his Resting position is pushed back, so that the second bearing ring 46 can dive back into the trough 42 of the rack 38 and thereby rotate.

As already mentioned, the second bearing ring 46, the rack 38 and the second gear 34 are movably mounted on the second base body 48 of the second fitting element 36. The second main body 48 also has a cutout 50, through which a display section 52 of the rack 38 can be pushed out of the second fitting element 36. The display portion 52 is always out of the second fitting member 36 when the Verrieglungsabschnitt 40 is brought into engagement with the flattening 44 and thus rotation of the second bearing ring 46 is blocked.

As can be seen from the orientation of the first and second directions 18, 20, a second handle designed as a door handle is shown in FIG Fig. 2 usually extend to the right. In order to ensure good visibility of the display section 52, the display section 52 is accordingly pushed to the left from the second fitting element 36. In order to achieve pushing out in this direction, the direction of rotation of the first gear 30 is reversed by the third gear 28 in the first fitting element 10.

To create a rotationally fixed coupling between the second bearing ring 46 and the second handle, the second bearing ring 46 comprises on its inner circumferential surface two opposing projections 54 which engage positively in a slot of the handle. Thus, in a blockage of the second bearing ring 46 is ensured by the rack 38, that the second handle and consequently also the second pin portion 16 of the actuating pin 15 can not be moved.

The first fitting element 10 and the second fitting element 36 each have a cover 56, which is identical for both fitting elements 10, 36. The covers 56 contribute to the mounting of the gears 28, 34, 30 and include corresponding bores 58 for this purpose. The covers 56 are symmetrically designed so that they are to be used for fitting arrangements for right- and left-opening doors and windows.

In Fig. 1 and Fig. 2 In each case, a cap 60 is shown, which forms a visually appealing conclusion of the fitting elements 10, 36. The cover caps 60 each have a central passage 62 for the corresponding handle. The cap 60 of the second fitting element 36 further comprises an emergency opening 64, through which the second gear 34 is accessible and by means of a suitable tool, for example by means of Allen screwdriver, rotated to manually cancel the lock of the second bearing ring 46 in an emergency.

In Fig. 3 an alternative embodiment of the second fitting element 36 is shown, which corresponds to the embodiment of Fig. 2 is largely similar. Unlike the embodiment of Fig. 2 is in the embodiment of Fig. 3 the display section 52 not from the second Base 48 pushed out when the second bearing ring 46 is blocked by the rack 38. Instead, the rack 38 is moved only within the second body 48, wherein the rack 38 is guided by a guide cutout 66 of the cover 56. In addition, the cover cap 60 includes a display window 68, through which the display section 52 is visible from the outside in the locked state.

Fig. 5 shows a fitting assembly 70 with a first fitting element 10 and a second fitting element 36. The first and second fitting element 10, 36 are connected by an actuating pin 15, to which adjacent to the first fitting element 10, a first handle 72 and adjacent to the second fitting element 36 a second handle 74 are mounted rotationally fixed.

In Fig. 5 the first handle 72 is twisted in a second direction 20 to lock the fitting assembly 70. The first handle 72 is brought to a noticeable for an operator detent point, whereby the first handle 72 in the in Fig. 5 shown end engages mechanically and remains without further action in this end position.

The locked state is in each case displayed in a display window 68 of the second fitting element 36 (FIG. Fig. 5a ) and the first fitting element 10 (FIG. Fig. 5b ) is displayed.

In an emergency opening 64 ( Fig. 5a ) is a slotted insert 76 rotatably mounted, which can be rotated by a flat-head screwdriver and / or a coin. By turning the insert 76, the fitting assembly 70 can be unlocked in an emergency, as already explained above.

Fig. 6 shows a schematic representation of a second embodiment of a first fitting element 10. The cover 56 and the cap 60 are not shown. It shows Fig. 6a the first fitting element 10 in the rest position, ie in the unlocked state, and Fig. 6b the first fitting element 10 in the locked state.

The first fitting element 10 according to Fig. 6 is different from that of Fig. 1 in that the first bearing ring 14 is non-rotatably coupled to a first indicator ring 78. The first display ring 78 has a substantially circular sector-shaped extension region 80, which covers an angle range of about 100 °. At the extension portion 80, a lock indicator 82 is attached, which is formed as a circular colored surface.

If the fitting assembly 70 is brought from its unlocked state into the locked state, the first bearing ring 14 and thus also the first indicator ring 78 of the in Fig. 6a shown position in the Fig. 6b rotated position shown. Thus, the lock indicator 82 is located behind the display window 68 of the first fitting element 10 (FIG. Fig. 5a ), whereby the locked state is visually displayed.

Fig. 7 and 8th show a third embodiment of a second fitting element 36, wherein the cover 56 and the cover cap 60 are not shown. Fig. 7a and 7b show the second fitting element 36 in rest position, whereas Fig. 8a and 8b represent the locked state.

The third embodiment of the second fitting element 36 differs from the embodiment according to FIG Fig. 2 in that a second Indicator ring 84 is provided which is rotatably mounted relative to the second bearing ring 46 ( Fig. 7a . 8a ). The second indicator ring 84 has a toothing 85, which meshes with the second gearwheel 34. The second indicator ring 84 is in the Fig. 7b and 8b hidden.

The second indicator ring 84 is rotatably mounted about the axis of rotation of the actuating pin 15 around and has a substantially circular sector-shaped extension portion 86 which covers an angular range of about 55 °. At the extension portion 86, a lock indicator 88 is attached, which is formed as a circular colored surface. The extension region 86 is guided in a recess 90, which forms a stop for rotational movements of the extension region 86.

Furthermore, the third embodiment differs in the configuration of the second bearing ring 46 and the rack 38 of the embodiment according to Fig. 2 , The second bearing ring 46 has a rectangular extension 92 (FIG. Fig. 7b . 8b ) in the locked state ( Fig. 8b ) abuts flush with a step 94 of the rack 38, whereby rotation of the second bearing ring 46 is prevented.

The rack 38 has, adjacent to the step 94, a trough 42 which, in the unlocked state, permits rotation of the second bearing ring 46 (FIG. Fig. 7b ).

The rack 38 of this embodiment does not include a display section 52.

If the fitting assembly 70 from its unlocked state ( Fig. 7 ) in the locked state ( Fig. 8 ), the second gear 34 (in FIG Fig. 7 . 8th ) clockwise. This will be the second indicator ring 84 from the in Fig. 7a shown position in the Fig. 8a rotated position shown and the locking indicator 88 behind the display window 68 of the second fitting element 36 (FIG. Fig. 5b ) brought. At the same time, the rack 38 is moved from one position ( Fig. 7b ), which permits rotation of the second bearing ring 46, moves linearly to the right, whereby the rectangular extension 92 comes to rest on the step 94 and prevents rotation of the second bearing ring 46. The fitting assembly 70 is thus locked.

Upon actuation of the fitting assembly 70 rotational movements of the handles 72, 74 in the first and second directions 18, 20 by means of the projections 17, 54 are positively transferred to the bearing rings 14, 46. The shape of the first handle 72 is adapted to the first bearing ring 14 and the second handle 74 to the second bearing ring 46.
