According to the invention, a guide element (42, 73) for guiding a movement of the activator (24, 71) in a direction at an angle to the guide direction (20) is provided, and the activator (24, 71) is from an engagement position with the driver (28, 80) movable into a disengaged position.

Description

The invention relates to an acceleration and / or braking device for controlling at least one along a guide rail in a guide direction directed movement of a movable furniture part, with an activator and a movable in the guide direction driver, wherein the activator has a contact surface for engagement with the driver.

From the DE 10 2011 050 394 A1 a fitting for a movable furniture part in the form of a sliding door is known, which is guided over rollers in a guide rail on a furniture body. The fitting comprises a fixed to the furniture body self-closing with a movable driver, which can be brought into engagement with a arranged on the sliding door activator. In this way, the driver can slow down the sliding door via the activator in order to avoid a stop of the sliding door on the furniture body and the associated disadvantages. However, it is disadvantageous that the activator must be movable over the entire travel of the sliding door, so that this space can not be used otherwise. Especially with a center door that can be opened in both directions, problems arise for the installation of such a self-closing.

From the DE 20 2012 001 115 U1 is a sliding door cabinet with at least three door leaves known. The door leaves are movable along two mounting rails, wherein a combined acceleration and deceleration device is provided with a driving element which penetrates a mounting rail carrier. As a result, the acceleration and deceleration device can be arranged behind the mounting rail, which requires a comparatively large amount of installation space and makes assembly costly.

It is therefore an object of the invention to provide an acceleration and / or braking device that can make optimal use of the available space and is as little as possible visible.

This object is achieved by an acceleration and / or braking device with the features of claim 1. Preferred developments are the subject of the dependent claims.

In one aspect of the invention, a guide member is provided for guiding movement of the activator in a direction angular to the guide direction, and the activator is disengageable from an engaged position with the cam to a position. As a result, the installation space of the activator can also be better utilized in the guide direction, since the activator only has to be moved into an engagement position in the travel range of the driver if necessary. Outside the travel range, the installation space can be used for other purposes.

The specified acceleration and / or braking device is based on the consideration that a positive engagement between the driver and the activator in the guide direction must act to brake the moving furniture part with the driver in the guide direction, for example by a damper, or to accelerate. In the prior art, such as in a middle sliding door in a three-door sliding door cabinet at least, this positive locking in the guide direction prevents, however, that the movable furniture part seen in the guide direction can be moved behind the positive connection, so that, for example, the aforementioned middle sliding door either in or can only be opened against the direction of leadership.

The activator can be arranged either on the furniture body or on the moving furniture part. Accordingly, then arranged on the acceleration and / or braking device driver is attached to the other part, either on moving furniture or furniture body.

The activator can be arranged at an angle to the guide direction movably guided in the acceleration and / or braking device. In this way, the activator can be arranged in the range of movement of the furniture part to be moved and moved in the case of a positive fit to be produced in an engaged position and brought into engagement with the driver. This positive connection can be provided by a one-sided concern of contact surfaces on the driver and the activator.

The guide element can preferably be designed as a pivot bearing with a pivot axis about which the activator is pivotally mounted. In this way, the activator can be pivotally mounted on this pivot bearing and pivoted by any actuator in an engaged position or out of it. Instead of a pivot bearing could be provided as a guide element and a curve guide or other mechanism for moving the activator.

In one embodiment, the pivot axis is aligned parallel to the guide direction, so that short switching paths of the activator are made possible. Furthermore, a contact surface of the activator can be arranged on a protruding from the pivot bearing first lever arm, and the first lever arm is movable via a second lever arm projecting from the pivot bearing. On the second lever arm can act a fixed or movable actuator. The two lever arms can be integrally depending on the application and, for example, designed as angled in its longitudinal extent lever.

Preferably, the activator is held by the guide member to a holder. The holder thus provides the counterpart to the guide element on the activator ready, which may be, for example, the further pivot bearing part of the pivot bearing. On the holder also stops for limiting the pivoting movement of the activator can be provided.

The two lever arms preferably protrude from the pivot bearing in different radial directions. Preferably, the two lever arms clamped from the pivot axis of the pivot bearing seen in an opening angle between greater than 90 ° and less than 180 °, in particular between 110 ° and 170 °. In this way, the second lever arm, which acts as Betätigungshebelarm for the first, having the contact surface lever arm can be operated to move the first lever from the same side on which the driver is arranged, so that the corresponding switching device for moving of the second lever arm of the activator does not have to be arranged in the range of movement of the furniture part to be moved.

By a suitable design of the first lever arm, for example by the first lever arm is formed longer than the second lever arm, it can be achieved that the second lever arm is only slightly moved to bring the first lever arm in an engaged position or out of engagement with the driver.

To move the activator, switching elements arranged outside the movement range of the movable furniture part can move the second lever arm into the movement range of the movable furniture part and thus push out the first lever arm from the movement range of the movable furniture part and produce a positive connection with the driver.

In this case, a biasing element can be provided as an additional element or alternatively for one of the switching elements for biasing the activator to the driver in an engaged position or away from the driver in a non-engaged position. In this way, the activator can be brought into a forced rest position or a forced engagement position, so that the activator can not move unintentionally in the event of vibrations or other forces unintentionally applied to the activator. The biasing member can also be extended to a flip-flop mechanism, which also puts the activator in the engaged position with the driver in a forced rest position.

Preferably, the first switching element for the activator comprises a parallel to the guide direction aligned ramp, by means of which the activator is movable. The ramp may have on opposite sides an angular, not parallel to the guide direction formed portion which may be formed as a slope, arcuate contour or the like. About this switching element, the activator can be moved without a user must manually move the activator for establishing the engagement position. A second switching element for the activator is formed on both sides of the housing of a self-closing, wherein the also formed as a ramp switching elements cause the activator is pivoted in contact in the opposite direction. As well as the first switching element and this ramp can be formed as a slope, arcuate structure or the like.

In another embodiment, the activator is fixed to a top floor or a bottom of a furniture body and pivotally mounted about a vertical axis. Thereby, the activator can be arranged largely invisible within a furniture body and pivoted to be engaged or disengaged with a driver of the acceleration and / or braking device. In this case, a switching element can be provided on the movable furniture part, by means of which the activator is movable, so that a compact construction is made possible.

The acceleration and / or braking device is preferably used in a fitting for a piece of furniture, in particular sliding door fitting. But it is also possible to provide the acceleration and / or braking device in a pullout guide or a pivotable flap or door. Furthermore, an acceleration device for a movable furniture part can also be provided, for example as with an ejection mechanism or a latching mechanism.

A schematically illustrated furniture 2 includes a first outer door 4 , a middle door 6 and a second outside door 8th that's about to become a fitting 10 belonging running profile 12 on a top floor of a furniture body 14 are held displaceable. The following remarks are based on the center door 6 described in more detail. You can, however, in a manner not shown also arbitrarily on the two outer doors 4 . 8th be transmitted.

The middle door 6 is about two to the fitting 10 belonging inner barrel parts 16 in the running profile 12 in a leadership direction 20 kept kept. At the middle door 6 is also a fitting 10 belonging holder 22 fixed in which a movable in 5 shown activator 24 is held. The inner running parts 16 and the holder 22 can also be integrated as a common functional unit in a component. In addition, several activators can 24 at the middle door 6 be provided.

For fitting 10 also belongs to a 5 shown self-closing 26 of which in 1 just a driver 28 is shown attached to a housing 30 in the direction of leadership 20 is movably mounted. The driver 28 can with the activator 24 be positively engaged to the center door 6 over the activator 24 in the direction of leadership 20 to pull or dampen, so to slow down. After all, belong to the fitting 10 also to be described switching elements 32 and 64 ,

As in 5 shown, the sliding doors roll 4 and 8th on rollers 34 in the tread 12 in appropriate careers 36 be guided. The roles 34 for the two exterior doors 4 . 8th are at outside running parts 38 kept and in the of the furniture body 14 seen from a more distant career. The roles 34 for the middle door 6 are at the in 1 shown inner barrel parts 16 kept and in the to the furniture body 14 led adjacent career run. The running profile 12 includes a horizontally protruding bridge 39 under the one bar 41 can be pushed, a lift-out for an inner barrel part 16 forms. A second on the outer race 38 arranged latch 45 Can be used as a further lifting protection for the exterior doors 4 . 8th under the track 36 be moved vertically upwards.

The activator 24 is pivotable on a to the holder 22 belonging storage block 40 held. This is the activator 24 on an axis 42 pivotally mounted, the stationary on the storage block 40 is provided. The axis 42 can be designed as a bearing pin, of a bearing sleeve 49 of the activator 24 is surrounded.

From the axle 42 extends substantially radially a first lever arm 46 , at the radial end of a contact surface 48 is trained. In an opening angle 50 from about 165 ° to 175 ° to the first lever arm 46 extends at the activator 24 a second lever arm 52 radial to the axis 42 ,

The two lever arms 46 . 52 can be in a pan direction 54 move back and forth, the swivel range by stops on the bearing block 40 may be limited. Becomes the second lever arm 52 for example, counterclockwise 54 moved, becomes the first lever arm 46 also counterclockwise 54 moved and vice versa.

Furthermore, the activator 24 via a return element 58 in the form of a spring, for example a spiral spring, be biased in a pivoting direction, so that the activator 24 For example, always facing away from the direction of engagement of the driver 28 or to the driver 28 is pressed.

In 5 is the activator 24 shown in a position in which he from the switching element 32 is operated, which on a vertical web 44 of the running profile 12 is arranged. This is the switching element 32 on the second lever arm 52 of the activator. In contrast, the activator 24 in 8th shown in a position where it is not from the switching element 32 is actuated and with the first lever arm 46 and the contact surface 48 in a rest position, in which no engagement with the driver 28 is possible. The activator 24 lies in the direction of leadership 20 considered before the switching element 32 and is therefore in 8th also not shown cut.

Will the middle door 6 and thus the activator 24 from the in 8th shown position against the guide direction 20 pulled, then moves the second lever arm 52 of the activator 24 on the switching element 32 to. The switching element 32 points in the direction of leadership 20 considered in at its ends 9 shown ramps 62 on, which are designed as run-on slopes. These ramps 62 may be linear, arcuate or otherwise formed.

As soon as the second lever arm 52 of the activator 24 one of the ramps 62 of the switching element 32 touches, presses the corresponding ramp 62 the second lever arm 52 in the swing direction 54 , As a result, the first lever arm 46 arranged contact surface 48 also in the pivoting direction 54 and thus to the driver 28 moves and reaches a contact surface on the driver 28 , This positive connection of the contact surfaces acts in and against the guide direction 20 , so the driver 28 the movement of the lever arm 46 and the activator 24 and thus the middle door 6 accelerating or retarding.

In the present example, the driver delays 28 after establishing the positive connection with the contact surface 48 the movement of the center door 6 and move it over the activator 24 against the direction of leadership 20 considered in an in 5 illustrated rest position.

The middle door 6 and thus the activator 24 can recover from this rest position by pulling in or against the guide direction 20 be pulled out. The contact surface moves 48 on the first lever arm 46 on one at the housing 30 of self-collection 26 arranged switching element 65 on, as a ramp 64 is trained. By the simultaneous expiration of the switching element 32 trained ramp 62 and the supporting effect on the restoring force of the return element 58 Both are lever arms 46 . 52 and thus the form-fitting element 48 against the pivoting direction 54 emotional. Thus, the positive connection between the driver 28 and the contact surface 48 solved and the middle door 6 can become free again in or against the direction of leadership 20 move. Between the ramps 62 and 64 is a straight bar 63 intended.

The activator 24 is biased in the illustrated embodiment by a spring in an initial position. Of course, it is also possible to dispense with such a spring and to switch over several switching elements in the guide direction the activator in the desired position. In addition, on the activator 24 Instead of two levers also be provided more than two levers, so that at least two levers for switching the lever 46 with the contact surface 48 can be used. Furthermore, it is conceivable that the ramps 62 with the return element 58 or the ramps 64 with the return element 58 be combined. The ramps 64 Of course, they can also be made in one piece on the tread pattern 12 be educated.
