Description

Pivoting fitting and piece of furniture

Technical Field

The present invention relates to a pivot fitting, in particular for an adjustment section on an article of furniture according to the preamble of claim 1. The invention also relates to an article of furniture comprising such a pivot fitting.

Background

Pivot fittings of the type in question are known from many embodiment variants of the prior art. Thus, for example, from EP 2 544 567 B1 a pivot fitting is known in which two levers are lockable relative to each other via a brake mechanism. Such pivot fittings are used, for example, for fastening a backrest, a headrest, an armrest or a footrest (which is pivotably mounted on the body of an item of furniture) to the body of the item of furniture, in order to fix the backrest, the headrest, the armrest or the footrest in a desired position from a starting position with the aid of the pivot fitting.

In order to more steeply set or lock the headrest or armrest in the adjustment direction from the flat position in the starting position, such a brake fitting can be pivoted further in the adjustment direction, wherein the headrest or armrest is locked in the desired position direction opposite to the adjustment and can thus be loaded.

Such pivot fittings typically have a limited adjustment angle, wherein the maximum adjustment angle defines an upper switching area, which is located at the end of a possible adjustment stroke of the pivot fitting.

The switching region serves to be able to reset the pivot fitting back to its initial starting position. If the user accidentally moves past his desired position during the setting of the headrest or armrest, he must first pivot the pivot fitting into the up-switch position, then pivot the pivot fitting back to the starting position, and finally pivot the pivot fitting again to the desired braking position.

Disclosure of Invention

The object of the present invention is to provide a pivot fitting with which, on the one hand, this adjustment to the desired braking position is further simplified and which enables an enlarged adjustment range.

This object is achieved by a pivot fitting having the features of claim 1.

This object is also achieved by an article of furniture comprising a pivot fitting having the features of claim 10.

The pivot fitting according to the invention has a first lever and a second lever which are mounted such that they can pivot relative to each other about a common axis. The two levers can be locked in the reset direction in different angular positions relative to each other with the aid of a latching mechanism.

The latch mechanism has: gear teeth rotatably fixed to the second lever; a control panel mounted to pivot about a common axis; and a brake catch mounted pivotable on the first lever and loaded in the direction of the gear teeth, which engages with the gear teeth in a stop position of the pivot fitting.

The brake catch may disengage from the gear tooth when the second lever is pivoted a predetermined angle in the adjustment direction relative to the first lever. When the brake catch is disengaged from the gear teeth, the second lever may pivot in a reset direction.

In this case, the latching mechanism enables the two levers to be locked in arbitrary angular positions relative to each other and the pivoting movement to be switched from the adjustment direction to the return direction and vice versa.

Since the latching mechanism can be selectively switched in any angular position for a pivoting movement from the adjustment direction to the return direction or vice versa and for locking, in particular new functions can be achieved which cannot be achieved due to the currently limited adjustment range.

Thus, for example, the adjusting section can be adjusted in a locking manner to a stop on another section or component of the item of furniture, since in the pivot fitting according to the invention no so-called safety distance is necessary anymore, but in the pivot fittings known from the prior art this safety distance must be preserved for switching.

Furthermore, the resetting of the furniture section (which is designed, for example, as a headrest or armrest and is fastened to the furniture body by means of such a pivot fitting) is achieved in a simple and direct manner, since the user can now move the pivot fitting directly in the resetting direction, without first travelling through a predetermined up-switch region.

Finally, the pivot fitting according to the invention is characterized in that it can be used for various applications, since the two levers are not limited in their potential pivoting relative to each other, thereby creating a braking range of 360 °.

Advantageous embodiment variants of the invention are the subject matter of the dependent claims.

According to an advantageous embodiment variant, the latch mechanism has a control lever pivotably mounted on the first lever, a toothed control disc, a restarting element coupled to the brake catch and a blocking unit.

The toothed control disk is preferably coupled to the gear tooth h in a rotationally fixed manner in the adjustment direction and is rotatable relative to the gear tooth in a return direction blocked by the control lever. In this case, the control disk may be held in a position holding the brake catch disengaged from the gear teeth by the blocking unit and pivotable back into engagement with the gear teeth by the return element.

In this case, the blocking unit is in a preferred embodiment variant designed as a second lever pivotably mounted on the first lever, which can be coupled with the toothed control disk by means of a tooth and can be pressed against the brake catch near its free end, so that the brake catch is disengaged from the gear tooth.

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

The pivot fitting can thus be switched at any time from a free pivot in the adjustment direction to a pivot in the reset direction by means of a trigger handle or the like connected to the bowden cable.

By a simple small angle pivoting of the first lever in the adjustment direction, locking of the two levers in the desired angular position relative to each other then takes place.

According to another preferred embodiment variant, the toothed control disk has radial gear teeth which interact with the control rod and axial gear teeth which are pressed with spring elements against the axial end gear teeth of the gear teeth.

In this case, the spring element causes the toothed control disk to continuously press against the gear teeth. Due to the tooth alignment of the axial end face gear teeth of the gear teeth and the axial gear teeth of the toothed control disk, a rotationally fixed coupling of the toothed control disk with the gear teeth in the adjustment direction and a pivoting capability of the toothed control disk with respect to the gear teeth in the reset direction are achieved.

According to a further preferred embodiment variant, the control disk has a driver cam and a driver lobe for the pivotal coupling with the brake latch, wherein the end of the latch provided with at least one latch tooth is positioned between the driver cam and the driver lobe, thus resulting in an easy and reliable coupling of the brake latch with the control disk.

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

In this case, the stop, which is formed, for example, as a pin, preferably protrudes from the end face of the restarting element, against which the free end of the control rod can be pressed.

Detailed Description

In the following description of the drawings, terms such as up, down, left, right, front, rear, etc., refer specifically to exemplary illustrations and positions selected in the respective figures of the pivot fitting, lever, brake mechanism, gear teeth, brake catches, toothed control disc, etc. These terms should not be construed as limiting, i.e., the references may vary due to various operating positions or mirror-symmetrical designs, etc.

A first embodiment variant of the pivoting fitting according to the invention is indicated as a whole by reference numeral 1 in fig. 1.

The pivot fitting 1 has a first lever 2 and a second lever 3, the first lever 2 and the second lever 3 being mounted such that they can pivot relative to each other about a common axis D.

The pivot axis D is formed here by gear teeth 4, which gear teeth 4 are received in a rotationally fixed manner by means of a gear wheel 43 in a recess formed as a toothed ring 33 in the head 32 of the second lever 3. The head 22 of the first rod 2 is applied to the head 32 of the second rod 3.

To achieve the ability of the two levers 2, 3 to pivot more easily relative to each other, an O-ring 18 is inserted between the levers, which O-ring 18 is pulled through the gear 43 of the gear teeth 4 and holds the two at a predetermined distance from each other at the two surfaces of the heads 22, 32 of the levers 2, 3 facing each other. The core of the gear teeth 4 is in this case formed in the shape of a sleeve.

The pin 11a holding the two levers 2, 3 to each other is accommodated in the central accommodation 44 of the gear tooth 4. In this case, the T-shaped head section is located at one end of the sleeve, while the end of the gear teeth 4 provided with the gear wheel 43 is covered on the rear of the second rod 3 facing away from the first rod 2 with a retaining plate 11b fastened on the pin 11a.

Above the first lever 2, a latching mechanism composed of a plurality of parts is arranged, with which the two levers 2, 3 can be locked relative to each other in different angular positions along the reset direction R.

In this case, the latch mechanism has: the gear teeth 4 rotatably fixed to the second lever 3; and a control panel 7 mounted so as to be pivotable about a common axis D; and a detent catch 5a which is mounted so as to be pivotable on the first lever 2 and which is loaded in the direction of the gear teeth 4 and which engages with the gear teeth 4 in the catch position of the pivot fitting 1.

For locking, the gear teeth 4 have in this case ring gear teeth placed on a central sleeve 45 with radial gear teeth 41, in which the brake teeth 55a shown in fig. 2 and 3 engage.

In this case, the alignment of the teeth of the external gear teeth 41 of the gear teeth 4 and the teeth of the stop teeth 55a of the brake catch 5a is implemented such that the stop teeth 55a prevent the rotation of the gear teeth 4 in the return direction R and such that the gear teeth 4 can pivot about the rotation axis D in the adjustment direction.

When the second lever 3 is pivoted by a predetermined angle in the adjustment direction V with respect to the first lever 2, the brake catch 5a can be disengaged from the gear teeth 4 by the latch mechanism. Once this occurs, the second lever 3 can pivot in the return direction R with respect to the first lever 2.

In this case, the latch mechanism is designed so that: in the switching of the pivoting movement from the adjustment direction V to the return direction R and vice versa, the two levers 2, 3 are locked in any angular position relative to each other.

For this purpose, in both the first embodiment variant of the pivot fitting 1 shown in fig. 1 to 5 and in the second embodiment variant of the pivot fitting 1 shown in fig. 6 to 9, a control lever 8 mounted pivotable on the first lever 2, a toothed control disc 6, a restarting element 5b coupled to the brake latch 5a and a blocking unit 9a, 9b are provided.

In this case, the catch 5a is held pivotable on the first lever 2 via a pin 15 accommodated in a bore 26 on the first lever 2, the pin 15 being aligned parallel to the rotation axis D.

In both embodiment variants, the restarting element 5b is designed as a control catch, preferably formed in a mirror image to the catch 5a, in that the restarting element 5b is provided with no catch teeth 55a only, in contrast to the catch 5a.

The restarting element 5b is mounted such that, in addition to the catch 5a in the borehole 26, it can also be rotated on the first lever 2 with a further pin 15.

At the end of the gear tooth facing away from the pin 15 serving as a rotation axis, the compression spring 20 is accommodated in a respective spring receptacle 53a, 53b provided for this purpose of the brake catch 5a and the reactivation element 5b, so that the pivot of the brake catch 5a directly results in the application of a force via the compression spring 20 (in the form of a load or a bulge, depending on the pivoting direction) on the reactivation element 5b and vice versa.

Stops 54a, 54b, preferably formed as pins, are arranged on the upper side of the brake lock catch 5a and the restarting element 5b, and this restarting element 5b faces away from the head 22 of the first lever 2, close to the gear teeth 4. In this case, the sides of the stops 54a, 54b facing each other serve to contact the free end of the control rod 8 and the blocking unit 9a, which blocking unit 9a is also designed as a rod in the embodiment variant shown in fig. 1 to 5.

In this case, the control lever 8 and also the blocking unit 9a are pivotably fastened via a spacing rivet 12 on the head 22 of the first lever 2, in particular near the upper end of the head 22, on the side of the gear teeth 4 opposite the brake lock 5a and the restarting element 5 b.

The lever arms 82, 92a of the control lever 8 and the blocking unit 9a are in this case pre-mounted such that the free ends 83, 93a are inserted between the stops 54a, 54b of the brake lock catch 5a and the restarting element 5 b.

Each arm 82, 92a of the control lever 8 or the blocking unit 9a, respectively, is formed curved and has in each case a tooth 84, 94a on the inside, the tooth 84, 94a being engageable in a radial gear tooth 61, the tooth face of the radial gear tooth 61 facing radially outwards of the toothed control disk 6.

Fig. 10 shows a perspective detail of the toothed control disk 6, the gear teeth 4 and the spring element 10, the toothed control disk 6 being pressed onto the gear teeth 4 by the spring element 10.

As shown in this figure, the toothed control disk 6 has, in addition to radial gear teeth, axial gear teeth 62 that engage with the face gear teeth 42 of the gear teeth 4. The teeth of the face gear teeth 42 and the axial gear teeth 62 of the toothed control disk 6 are formed in this case such that the toothed control disk 6 is rotatably fixedly coupled with the gear teeth 4 in the adjustment direction V and is rotatable relative to the gear teeth 4 in such a way that it is blocked by the control lever 8 in the reset direction.

If the toothed control disk 6 is blocked with the control rod 8, the teeth of the axial gear teeth 62 of the toothed control disk 6 can slide over the teeth of the end gear teeth 42 of the gear teeth 4 and be pressed elastically against one another by the spring element 10.

The control disk 7 is mounted to be pivotable under radial gear teeth 41 of the gear teeth 4. In this case, the control disk 7 has a central recess for receiving the sleeve region of the gear teeth 4, which corresponds to the diameter of the gear wheel 43 and is formed by the annular portion 71 of the control disk 7.

On the edge of the ring 71 facing the brake lock catch 5a and the restarting element 5b, a driver projection 72 and a driver lobe 73 are formed, the driver projection 72 and the driver lobe 73 extending upwards from the plane of the ring 71 in the direction of the brake lock catch 5a and the restarting element 5 b.

In this case, the end of the brake lock 5a adjacent to the gear tooth 4 is clamped between the driver projection 72 and the driver lobe 73, and thus the pivoting movement of the brake lock 5a results in a corresponding pivoting movement of the control disk 7.

The latch mechanism top is covered by a cover 19, which cover 19 is used to house the pin 11a with a housing 191.

Furthermore, a separating plate 17, which is mainly used to ensure a precise pivoting movement of the control lever and the blocking unit 9a, is arranged between the control lever 8 and the blocking unit 9a on the one hand and the brake lock 5a and the restarting element 5b on the other hand.

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

The bowden cable is in this case coupled directly to the control disk 7a using an end piece 92 b.

For this purpose, the control disk 7a is formed with a coupling portion 74a, which coupling portion 74a extends radially from the annular portion 71a of the control disk 7a and thus causes a pivoting movement of the control disk 7a by actuating the bowden cable 9b.

The pull wire 91b of the bowden cable 9b is fastened to the fastening element 2a of the first rod 2 provided for this purpose by means of the fastening element 93b and the attachment 94 b.

The fastening element 2a is in the embodiment variant shown here preferably designed as a separate component which can be fastened to the lever arm 21 of the first lever 2. It is also conceivable to form the first rod 2 in such a way that the bowden cable can be fastened directly to the first rod 2.

The function of both embodiment variants will be explained below.

Fig. 2 shows the pivot fitting 1 according to the variant of the embodiment shown in fig. 1 to 5 in a braking position. In this case, the stop tooth 55a of the brake lock catch 5a engages with the radial gear tooth 41 of the gear tooth 4. Thus, a load of the pivot fitting 1 in the return direction R is possible. Adjustment of the pivot fitting 1 in the adjustment direction V is possible.

In this case, the adjustment of the pivot fitting 1 takes place by a rotational movement of the second lever 3, wherein the gear teeth 4 are held rotatably fixed. With this rotational movement of the gear teeth 4, the brake lock catch 5a is pressed out of the external gear teeth 41 of the gear teeth 4. At the same time, the control disk 7 is also pivoted, which is mounted rotatably about the gear teeth 4 and encloses a brake catch between the driver projection 72 and the driver lobe 73.

When the gear teeth 4 are rotated further in the adjustment direction V, during which the toothed control disk 6 is also rotated, the radial gear teeth 61 of the toothed control disk 6 guide the blocking unit 9a further by pressing the teeth 94a further out of the blocking unit 9a, which blocking unit 9a is embodied here as a lever.

In this case, the free end 94a of the blocking unit 9a presses against the stop 54a of the catch 5a and thus brings the catch 5a further out. This position is shown in fig. 3, where it can be seen that the stop tooth 55a of the brake catch 5a is held disengaged from the radial gear tooth 41 of the gear tooth 4.

In this position, the pivot fitting 1 can now be adjusted in the return direction R. This is because the deflection of the brake catch 5a causes the restarting element 5b to pivot due to the compression spring 20 and the end of the restarting element 5b approaches the gear teeth 4 towards the gear teeth 4.

In this case, the control lever 8 is pressed sufficiently towards the toothed control disk 6 by the stop 54b, so that the teeth 84 of the control lever 8 engage with the radial gear teeth 61 and thus block the pivoting of the toothed control disk 6.

During pivoting of the gear teeth 4 in the resetting direction, the toothed control disk 6 is pushed axially upwards via the face gear teeth 42 of the gear teeth 4 and the tooth geometry of the axial gear teeth 62 of the toothed control disk 6, wherein the spring element 10, which is here designed as a leaf spring, ensures that the toothed control disk 6 is always pressed axially against the gear teeth 4 by the pressure on the toothed control disk 6.

Thus, during a resetting movement in the resetting direction R, during a movement of the pivot fitting 1a rocking axial movement of the toothed control disk 6 occurs, which is also referred to as a reverse mode.

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

In this case, the toothed control disk 6 presses the control lever 8 out of engagement with the toothed control disk 6 while pressing its free end 83 against the stop 54b of the restarting element 5b, whereby the end of the restarting element 5b that is close to the gear teeth 4 pivots away from the gear teeth 4.

Accordingly, the pressure on the brake lock catch 5a is increased via the compression spring 20. Once the teeth 94a of the blocking unit 9a can be engaged in the radial gear teeth 61 of the toothed control disk 6, the brake catch 5a is pressed back into the engagement area of the radial gear teeth 41 of the gear teeth 4 by the compression spring 20.

In this case too, the control disk 7 moves together and thus the pivot fitting 1 reaches the initial braking position again.

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

In the embodiment variant of the pivot fitting 1 shown in fig. 6 to 9, in which a blocking unit 9b designed as a bowden cable is installed, fig. 7 shows the braking position of the pivot fitting 1 instead of the blocking unit 9a designed as a lever.

Here, the brake teeth 55a of the brake lock catch 5a are also engaged with the radial gear teeth 41 of the gear teeth 4. Here too, a load in the reset direction R is ensured. The adjustment in the adjustment direction V can be achieved by a latch mechanism.

Here, in order to achieve a pivoting movement of the second lever 3 in the resetting direction, the bowden cable is actuated, which causes the control disk 7a to pivot in the adjustment direction V.

In this case, the brake catch 5a is disengaged from the radial gear teeth 41 of the gear teeth 4 by the driver lobe 73 a.

Thus, the pivoting of the restarting element 5b is also caused by the compression spring 20, so that the control lever 8, by means of its teeth 84, engages with the radial gear teeth of the toothed control disk 6 and thus blocks the pivoting of the toothed control disk 6.

This additionally makes a single trigger of the blocking unit 9b designed as a bowden cable sufficient to disengage the blocking and perform the reversal of the second lever 3 in case of discontinuous actuation of 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 here also driven using the gear teeth 4.

At the same time, the control lever 8 is again pressed out of engagement with the radial gear teeth 61 of the toothed control disk 6.

In this case, the free end 83 of the control lever 8 again pushes the restarting element 5 away from the gear teeth 4, wherein the catch lock 5a is pivoted back into the lock position shown in fig. 7 by the coupling of the restarting element 5b with the catch lock 5a via the compression spring 20.

In an exemplary embodiment of the present invention for adjusting a backrest, armrest, footrest or headrest on an article of furniture, a horizontally aligned pivot axis D of a movable furniture component relative to a furniture body is generally provided.

It should be noted that other applications are possible in which the pivot axis is aligned vertically or diagonally in space. For example, the backrest of the item of seating furniture can also be pivoted about the vertical pivot axis D and thus not adjust the inclination of the remaining part, but rather the angular position of the remaining part in space.
