EP3400835B1 - Pivot fitting and furniture - Google Patents

Description

The present invention relates to a swivel fitting, in particular for adjustment segments on furniture according to the preamble of claim 1. The invention further relates to a piece of furniture with such a swivel fitting.

Generic pivot fittings are known in numerous design variants from the prior art. For example, from the EP 2 544 567 B1 a pivot fitting is known in which two levers can be locked relative to each other via a locking mechanism. Such pivot fittings are used, for example, to attach a backrest, headrest, armrest or footrest pivotably mounted on a body of a piece of furniture to the body of the piece of furniture, in order to fix them in a desired position from a starting position using the pivoting fitting.

In order to adjust or lock the headrest or armrest more steeply from a flat position in an initial position in an adjustment direction, such a locking fitting can be pivoted further in the adjustment direction, the headrest or armrest locking in the desired position against the adjustment direction and thus resilient is.

Such swivel fittings usually have a limited adjustment angle, the maximum adjustment angle defining an upper switching range which is at the end of the possible adjustment path of the swivel fitting.

This changeover area serves to be able to reset the swivel fitting back to its initial starting position. If the user accidentally passes the desired position when adjusting the headrest or armrest, he must first swivel the swivel fitting into the upper switchover position, then swivel the swivel fitting back into the starting position and finally swivel it again into the desired locking position.

From the DE 10 2012 104 974 A1 a pivot fitting is known in which two teeth formed on respective levers by actuating one Hand lever against the force of a compression spring positioned between the levers can be pressed apart in any angular position of the lever

From the DE 601 06 811 T2 an adjustment mechanism for such a pivot fitting is known, in which a locking element and a crown are provided on mutually facing sides with a toothing over a full circumference. The locking element and the crown are pressed together by a compression spring. The crown has windows through which the legs of a separating element project in the direction of the locking element, which is positioned on a surface of the crown facing away from the locking element. With the aid of a wedge that can be actuated from the outside, the separating element can be advanced further in the direction of the blocking element, so that the teeth between the blocking element and the crown disengage.

The object of the present invention is to provide a swivel fitting which, on the one hand, further simplifies such an adjustment process into a desired latching position and which enables an enlarged adjustment range.

This object is achieved by a swivel fitting with the features of claim 1.

The object is further achieved by a piece of furniture with such a swivel fitting with the features of claim 10.

The swivel fitting according to the invention has a first lever and a second lever, which are pivotably mounted to one another about a common axis. The two levers can be locked relative to each other in a reset direction by means of a ratchet mechanism in different angular positions.

The pawl mechanism has a toothing fixed in a rotationally fixed manner on the second lever, a control disk mounted pivotably about the common axis and a latching pawl pivotably mounted on the first lever and loaded in the direction of the toothing, which is in engagement with the toothing in a latching position of the pivot fitting.

When the second lever is pivoted by a predetermined angle relative to the first lever, the catch is disengaged from in an adjustment direction the gearing can be brought. When the latch is disengaged from the toothing, the second lever can be pivoted in the reset direction.

The ratchet mechanism enables the two levers to be locked and the pivoting movement to be switched from the adjustment direction to the reset direction and vice versa in any angular position relative to one another.

The pawl mechanism has a control lever pivotally mounted on the first lever, a toothed control disk, a reactivation element coupled to the latching pawl and a blocking unit.

The possibility of switching the ratchet mechanism for a pivoting movement from the adjustment direction into the reset direction and vice versa and the locking in any angular positions make it possible in particular to implement new functions which are not possible due to the adjustment range restricted today.

For example, adjustment segments can be locked until they stop against another segment or component of the piece of furniture, since with the swivel fitting according to the invention, a so-called safety distance, which must be maintained for switching over with the swivel fittings known from the prior art, is no longer necessary.

Furthermore, the resetting of a furniture segment, for example designed as a headrest or armrest, which is attached to a furniture body via such a swivel fitting, is made possible in a simple and direct manner, since the user can now move the swivel fitting directly in the reset direction without first having to predefine it the upper switching range.

Finally, the pivot fitting according to the invention is characterized in that such pivot fitting can be used for a large number of applications due to the unlimited pivoting of the two levers relative to one another, which results in a 360 ° locking range.

Advantageous embodiments of the invention are the subject of the dependent claims.

The toothed control disk is preferably coupled to the toothing in a rotationally fixed manner in the adjustment direction and blocked in the return direction by the control lever and rotatable relative to the toothing. The control disk can be held by the blocking unit in a position holding the latching pawl out of engagement with the toothing and can be pivoted back into engagement with the toothing by the reactivating element.

In a preferred embodiment variant, the blocking unit is designed as a second control lever pivotably mounted on the first lever, which can be coupled to the toothed control disc via a tooth and can be pressed against the latching pawl in the region of its free end in such a way that it comes out of engagement with the toothing.

In an alternative embodiment variant, the blocking unit is designed as a Bowden cable coupled to the control disk.

This makes it possible to switch the swivel fitting from a free swivel in the adjustment direction to a swivel in the reset direction at any time via a release handle or the like connected to the Bowden cable.

The locking in a desired angular position of the two levers relative to one another then takes place by simply pivoting the first lever at a small angle in the adjustment direction.

According to a further preferred embodiment variant, the toothed control disk has radial toothing interacting with the control lever and an axial toothing pressed with a spring element against an axial end face toothing of the toothing.

The spring element brings about a constant pressing of the tooth control disc onto the toothing. By aligning the teeth of the axial end face toothing of the toothing and the axial toothing of the toothed control disk, the rotationally fixed coupling of the toothed control disk with the toothing in the adjustment direction and the rotatability of the toothed control disk relative to the toothing in the reset direction is achieved.

According to a further preferred embodiment variant, the control disk for the swivel coupling with the latching pawl has a driver knob and a driver tab, with an end of the latching pawl provided with at least one latching tooth being positioned between the driver knobs and the driver tab, whereby an easily producible and reliable coupling of the latching pawl to the Control disc is effected.

According to a preferred embodiment variant, the reactivation element is designed as a control pawl which is coupled to the latching pawl via a compression spring and is pivotably mounted on the first lever.

In this case, a stop, for example in the form of a bolt, protrudes from an end face of the reactivation element, against which a free end of the control lever can be pressed.

In the following description of the figures, terms such as top, bottom, left, right, front, rear, etc. refer exclusively to the exemplary representation and position of the swivel fitting, the lever, the pawl mechanism, the toothing, the latching pawl, and the toothed control disk selected in the respective figures and the same. These terms are not to be understood as restrictive, that is to say that these references can change due to different working positions or the mirror-symmetrical design or the like.

In Figure 1 a first embodiment variant of a swivel fitting according to the invention is designated overall by reference number 1.

The pivot fitting 1 has a first lever 2 and a second lever 3, which are pivotably mounted relative to one another about a common axis D.

The pivot axis D is formed here by a toothing 4 which is rotatably received in a lever head 32 of the second lever 3 by a gear 43 in a recess designed as a toothed ring 33. A lever head 22 of the first lever 2 is placed on the lever head 32 of the second lever 3.

To make it easier for the two levers 2, 3 to pivot relative to one another, an O-ring 18 is inserted between the levers, which is slipped over the toothed wheel 43 of the toothing 4 and the two on the facing surfaces of the lever heads 22, 32 of the levers 2, 3 in one holds predetermined distance from each other. A core of the toothing 4 is sleeve-shaped.

In a central receptacle 44 of the toothing 4, a bolt 11a is held, which holds the two levers 2, 3 together. Here, a T-shaped head section rests on one end of the sleeve, while the end of the toothing 4 provided with the gear 43 is covered on the rear side of the second lever 3 facing away from the first lever 2 with a retaining disk 11b, which is fastened to the bolt 11a is.

Arranged above the first lever 2 is a latch mechanism consisting of a large number of components, with which the two levers 2, 3 can be locked in different reset positions relative to one another in a reset direction R.

The pawl mechanism has the toothing 4, which has already been fixed in terms of rotation on the second lever 3, as well as a control disk 7 pivotably mounted about the common axis D and a latching pawl 5a pivotably mounted on the first lever 2 and loaded in the direction of the toothing 4, which is in a latching position the pivot fitting 1 is in engagement with the toothing 4.

For latching, the toothing 4 has an annular toothing with a radial toothing 41, which is placed on the central sleeve 45 and into which an in Figure 2 and 3 shown locking tooth 55a engages.

The alignment of the teeth of the external toothing 41 of the toothing 4 and the detent tooth 55a of the detent pawl 5a is carried out in such a way that the detent tooth 55a blocks rotation of the toothing 4 in the reset direction R and enables the toothing 4 to be rotated in the adjustment direction about the axis of rotation D.

The latching pawl 5a can be brought out of engagement with the toothing 4 by the pawl mechanism when the second lever 3 is pivoted by a predetermined angle relative to the first lever 2 in an adjustment direction V. As soon as this is the case, the second lever 3 can be pivoted in the reset direction R relative to the first lever 2.

The pawl mechanism is designed such that it enables the two levers 2, 3 to be locked in a switchover of the pivoting movement from the adjustment direction V to the reset direction R and vice versa in any angular positions relative to one another.

This is both in the in the Figures 1 to 5 shown first embodiment of the pivot fitting 1 as well as in the Figures 6 to 9 shown second embodiment of the pivot fitting 1, a control lever 8 pivotably mounted on the first lever 2, a toothed control disk 6, a reactivating element 5b coupled to the latching pawl 5a and a blocking unit 9a, 9b.

The pawl 5a is pivotally held on the first lever 2 via a pin 15, which is accommodated in a bore 26 on the first lever 2 and is oriented parallel to the axis of rotation D.

In both design variants, the reactivating element 5b is designed as a control pawl which is preferably a mirror image of the latching pawl 5a and, in contrast to the latching pawl 5a, is merely not provided with a latching tooth 55a.

The reactivating element 5b is rotatably supported by a further pin 15 next to the latch 5a in a bore 26 in the first lever 2.

At one end facing away from the pin 15 of the toothing serving as the axis of rotation, a compression spring 20 is accommodated in respective spring receptacles 53a, 53b of the latching pawl 5a and the reactivating element 5b, so that pivoting of the latching pawl 5a immediately exerts a force on the compression spring 20 (in Form of a load or a relief, depending on the pivoting direction) on the reactivating element 5b and vice versa.

On an upper side of the latching pawl 5a and the reactivating element 5b facing away from the lever head 22 of the first lever 2, stops 54a, 54b, preferably designed as bolts, are arranged near the toothing 4. The mutually facing lateral surfaces of these stops 54a, 54b serve to abut free ends of the control lever 8 and one in the in the Figures 1 to 5 The embodiment variant shown also designed as a blocking unit 9a.

Both the control lever 8 and the blocking unit 9a are each pivotably attached to the lever head 22 of the first lever 2 via a spacer rivet 12, namely near an upper end of the lever head 22 on a side of the toothing 4 opposite the latching pawl 5a and the reactivating element 5b.

The lever arms 82, 92a of the control lever 8 and the blocking unit 9a are preassembled in such a way that the free ends 83, 93a lie between the stops 54a, 54b of the latching pawl 5a and the reactivation element 5b.

Each of the arms 82, 92a of the control lever 8 or the blocking unit 9a is arcuate and each has a tooth 84, 94a on the inside, which is capable of engaging in a radial toothing 61 with teeth of a toothed control disk 6 pointing radially outward.

Figure 10 shows a perspective detailed view of this tooth control disc 6, the toothing 4 and a spring element 10 with which the tooth control disc 6 is pressed onto the toothing 4.

As shown in this figure, the toothed control disk 6 has, in addition to the radial toothing, an axial toothing 62 which is in engagement with an end face toothing 42 of the toothing 4. The teeth of the face gearing 42 and the axial toothing 62 of the toothed control disk 6 are shaped in such a way that the toothed control disk 6 is coupled to the toothing 4 in a rotationally fixed manner in the adjustment direction V and can be rotated in the reset direction by the control lever 8 relative to the toothing 4.

If the toothed control disk 6 is blocked with the control lever 8, the teeth of the axial toothing 62 of the toothed control disk 6 can slide over the teeth of the end face toothing 42 of the toothing 4 and are resiliently pressed against one another by the spring element 10.

A control disk 7 is pivotably mounted below the radial toothing 41 of the toothing 4. The control disk 7 has a central recess for receiving a sleeve region of the toothing 4 corresponding to the diameter of the gear 43, which is formed by an annular piece 71 of the control disk 7.

On one edge of the ring piece 71 facing the latching pawl 5a and the reactivating element 5b, a driver knob 72 and a driver tab 73 are formed, which extend upwards from the plane of the ring member 71 in the direction of the latching pawl 5a and the reactivating element 5b.

The end of the pawl 5a near the toothing 4 is clamped between the driver knobs 72 and the driver tab 73 so that a pivoting movement of the latching pawl 5a leads to a corresponding pivoting movement of the control disk 7.

The pawl mechanism is covered at the top by a cover 19 which, with a receptacle 191, serves to receive the bolt 11a.

Furthermore, a separating plate 17 is provided between the control lever 8 and the blocking unit 9a on the one hand and the latching pawl 5a and the reactivating element 5b on the other hand, which primarily serves to ensure the exact pivoting movement of the control lever and the blocking unit 9a.

In contrast to that in the Figures 1 to 5 Design variant of the pivot fitting 1 shown in the in the Figures 6 to 9 In the embodiment variant of the pivot fitting 1 shown, a blocking unit 9b designed as a Bowden cable is installed instead of the blocking unit 9a designed as a pivot lever.

The Bowden cable is coupled with an end piece 92b directly to the control disk 7a.

For this purpose, the control disc 7a is formed with a coupling part 74a, which extends radially from the ring piece 71a of the control disc 7a, so that a pivoting movement of the control disc 7a is caused by actuating the Bowden cable 9b.

The pull wire 91b of the Bowden cable 9b is fixed via a fixing element 93b and a connecting piece 94b to a fastening piece 2a of the first lever 2 provided for this purpose.

In the embodiment variant shown here, the fastening element 2a is preferably designed as a separate separate component that can be fixed on the lever arm 21 of the first lever 2. It is also conceivable to shape the first lever 2 in such a way that the Bowden cable can be attached directly to it.

The mode of operation of the two design variants is explained below.

The pivot fitting 1 according to the Figures 1 to 5 variant shown is in Figure 2 shown in a rest position. The latching tooth 55a of the latching pawl 5a is in engagement with the radial toothing 41 of the toothing 4. This enables the pivoting fitting 1 to be loaded in the reset direction R. An adjustment of the pivot fitting 1 is possible in the adjustment direction V.

The swivel fitting 1 is adjusted via a rotary movement of the second lever 3, in which the toothing 4 is held in a rotationally fixed manner. This rotary movement of the toothing 4 pushes the detent 5a out of the external toothing 41 of the toothing 4. The control disk 7, which is rotatably mounted about the toothing 4 and surrounds the detent pawl between the driver knobs 72 and the driver tab 73, is also pivoted.

When the toothing 4 continues to rotate in the adjustment direction V, in which the toothed control disk 6 is also rotated, the radial toothing 61 of the toothed control disk steers 6 the blocking unit 9a, which is designed here as a lever, by pushing out the tooth 94a of the blocking unit 9a.

The free end 94a of the blocking unit 9a presses against the stop 54a of the latch 5a and thus further deflects the latch 5a. This position is in Figure 3 shown, in which it can be seen that the latching tooth 55a of the latching pawl 5a is kept out of engagement with the radial toothing 41 of the toothing 4.

In this position it is now possible to adjust the swivel fitting 1 in the reset direction R. This is because the deflection of the latch 5a causes the reactivation element 5b to be pivoted by the compression spring 20 with its end near the toothing 4 towards the toothing 4.

The control lever 8 is pressed so far towards the tooth control disc 6 via the stop 54b that the tooth 84 of the control lever 8 engages in engagement with the radial toothing 61 and thus blocks rotation of the tooth control disc 6.

During the rotation of the toothing 4 in the restoring direction, the tooth control disk 6 is pressed axially upward via the tooth geometry of the end face toothing 42 of the toothing 4 and the axial toothing 62 of the tooth control disk 6, the spring element 10, which is designed here as a leaf spring, ensuring by pressure on the tooth control disk 6, that the toothed control disk 6 is always pressed axially against the toothing 4.

This results in a rocking axial movement of the toothed control disk 6 during the movement of the swivel fitting 1 in the return movement in the return direction R, which is also referred to as the reversing mode.

If the direction of rotation of the second lever 3 is reversed again, that is to say moved again in the adjustment direction V, the toothed control disk 6 is also moved again with the toothing 4.

The toothed control disk 6 presses the control lever 8 out of engagement with the toothed control disk 6 and thereby presses with its free end 83 against the stop 54b of the reactivating element 5b, so that the end of the reactivating element 5b near the toothing 4 is pivoted away from the toothing 4 ,

As a result, the pressure force on the latch 5a is increased via the compression spring 20. As soon as the tooth 94a of the blocking unit 9a can then engage in the radial toothing 61 of the toothed control disk 6, the latching pawl 5a is pressed back into the engagement area of the radial toothing 41 of the toothing 4 by the compression spring 20.

The control disk 7 is also taken along, so that the pivot fitting 1 again reaches the original latching position.

The pivot fitting 1 can then be loaded again in the reset direction.

At the in Figures 6 to 9 The variant of the swivel fitting 1 shown, in which the blocking unit 9b designed as a Bowden cable is installed instead of the blocking unit 9a designed as a lever, is shown in FIG Figure 7 the locking position of the pivot fitting 1 shown.

Here, too, the locking tooth 55a of the locking pawl 5a is in engagement with the radial toothing 41 of the toothing 4. A load in the reset direction R is also guaranteed here. An adjustment in the direction of adjustment V is made possible by the pawl mechanism.

In order to enable a pivoting movement of the second lever 3 in the return direction, the Bowden cable is actuated, which leads to a pivoting of the control disk 7a in the adjustment direction V.

In this case, the detent pawl 5a is taken out of engagement with the radial toothing 41 of the toothing 4 by the driver tab 73a.

As a result, the reactivation element 5b is also pivoted via the compression spring 20 in such a way that the control lever 8 engages with its tooth 84 with the radial toothing of the toothed control disk 6 and thus blocks it against rotation.

This also makes it possible that a single triggering of the blocking unit 9b designed as a Bowden cable is sufficient to take the blocking out of action and to reverse the second lever 3 without permanently actuating the Bowden cable.

If the pivoting direction of the second lever 3 is to be reversed again in the adjustment direction V, the toothed control disk 6 is again driven with the toothing 4 here.

The control lever 8 is pressed out of engagement with the radial toothing 61 of the toothed control disk 6 again.

The free end 83 of the control lever 8 in turn presses the reactivating element 5 away from the toothing 4, whereby by coupling the reactivating element 5b with the latching pawl 5a via the compression spring 20 the latching pawl 5a back into the Figure 7 shown rest position is pivoted.

In the mentioned application examples of the invention for adjusting backrests, armrests, footrests or headrests on furniture, there is generally a horizontally oriented pivot axis D of the movable furniture part relative to the furniture body.

It is pointed out that other applications in which the pivot axis is oriented vertically or obliquely in space are also possible. For example, a backrest of a piece of seating furniture can also be rotatable about a vertical pivot axis D, so that one does not adjust the backrest inclination, but rather the angular position of the backrest in the room.
