Description

An accelerating or braking device

The present invention relates to an acceleration or braking device for furniture or household appliances, which may be movable along a guide track, comprising a catch having a receiving means, wherein a section of the activator engages the guide track against the force of a damper. Thus, it can be inserted into the receiving means to move the catch, and the activator is applied to the contact surface of the catch when hitting the catch.

DE 10 2012 109 752 discloses an ejector device with a pull-out guide comprising a movable running rail with an activator.

The activator is formed as a flexible lever, and a projection can be inserted into the receiving means of the catch to move the catch along the guide track.

The catch is coupled to a latching mechanism, whereby the drawer can be latched into the closed position.

As a result of the formation of the activator as a flexible lever, in this case, when the projection is pressed out of the receiving means of the catch, skipping may occur, the mechanism described above provides for a crude use for the damping device and , a large impact force can be generated to decelerate the movable drawer element.

To prevent such skipping, it is proposed in EP 2 401 941 to guide a catch along a guide track with a self-retracting mechanism, the catch being able to connect with the protrusion of the activator.

The guide track for the catch includes a cover adjacent the angled end section, whereby the activator is prevented from moving out of the receiving means of the catch.

Accordingly, the cover can fix the coupling between the catch portion and the activator, but the cover requires additional installation space.

Therefore, it is an object of the present invention to provide an acceleration or braking device for furniture or household appliances which ensures a safe coupling of an activator and a catch part in a compact configuration.

This object is realized by an acceleration or braking device having the technical features of claim 1 .

In the acceleration or braking device according to the present invention, the catch part is movable along the guide track, the activator is held on the contact surface of the catch part while striking the catch part, the contact surface, wherein the section of the activator is the contact surface It is arranged in a partially inclined manner with respect to a direction perpendicular to the direction of movement of the catch part, so as to pivot inside the receiving means when striking the .

Thus, skipping of the activator on the catch is prevented, since, upon striking of the activator on the catch, the force is provided in a purposeful manner, to prevent jumping out of the receiving means, The force pivots the section of the activator inside the receiving means.

A slight pivoting movement of the section of the activator, in addition to the secure coupling of the catch to the activator, can also absorb a certain amount of impact energy, which is particularly effective in case of large damping forces.

The acceleration or braking device can be used, in particular, in sliding dongles or drawers for furniture or household appliances, as a result of which it is possible to safely prevent malfunction of the sliding element.

The inclined area of the contact surface forms a sliding surface for pivoting the activator to a certain extent.

According to a preferred embodiment of the present invention, the inclination of the contact surface with respect to the direction perpendicular to the direction of movement of the catch is inclined at an angle between 4° and 30°, in particular between 6° and 20°.

The contact surface is not formed in a linear manner, but may extend at least partially in a curved manner.

During striking on the contact surface of the activator, the force generated by the inclination of the contact surface ensures a certain amount of pivoting of the activator inside the receiving means, the magnitude of the pivoting movement being dependent on the damping force .

The pivot path can therefore lie in a range between 0.1 mm and 5 mm, in particular between 0.5 mm and 3 mm, the contact surface forming a sliding surface for the catch.

The contact surface may include a limit stopper or non-inclined section to limit the pivot path of the activator.

Said receiving means are preferably formed in a substantially U-shaped manner and comprise two sidewalls and a base.

The contact surface may be formed on a side wall of the receiving means, such that upon striking an activator on the contact surface the end section pivots with respect to the base of the receiving means.

The activator also includes a surface held on the contact surface and disposed in an inclined manner with respect to a direction perpendicular to the direction of movement of the catch portion.

Thus, the impact force can be distributed over a larger area of one face, and the inclination of one face of the activator held on the contact surface can be chosen to be equal to the inclination of the contact face when the driver is moved along the linear section of the guide track. have.

An inclination of one surface with respect to a direction perpendicular to the movement direction of the catch part may be disposed at an angle between 4° and 30°, in particular, between 6° and 20°.

It is also possible to roughen the contact surface on the catch and/or the one surface on the activator which is in contact with the contact surface by suitable means or coating, providing a lubricant coating to allow for the required change in the coefficient of friction of the two surfaces. limit is possible.

In a further embodiment, the activator is formed in a web-like manner and fixed on the opposite side of the section for coupling with the catch.

The activator may form a lever between the fixing point and the section coupled to the catch, the lever having a length of between 1 cm and 8 cm, in particular between 3 cm and 6 cm.

The activator is preferably arranged substantially parallel to the direction of movement of the catch, as a result of which only a very small installation space is required perpendicular to the direction of movement.

The moving direction of the catch part may be formed parallel to the running rail of the sliding door fitting or the pull-out guide.

The guide track for the catch may be formed in a substantially linear manner and comprise at least one angled end section, on which the catch may be latched.

As a result, the catch can be pivoted and unlocked first, since, after striking the activator on the contact surface, the latching on the angled end section is released, the relative movement between the activator and the guide track is the actuation of the catch. can be braked by

Dampers, in particular linear dampers, are preferably used for this purpose, the dampers providing a sufficient damping force for the respective purpose.

Each damper is operable as a fluid damper, in particular a fluid damper with oil moved within the damper housing by a piston.

The acceleration or braking device according to the invention can be used in particular for fitting a sliding door on the bottom side of a sliding door, for example to brake a movement of a closing motion.

The guide track may be formed on a housing which is fixed to the sliding door, as a result of which the activator is fixed in a fixed manner on the furniture or household appliance.

It is also clearly possible to fasten the activator to the sliding door and to provide a guide track to the housing in a fixed manner on a furniture body.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an acceleration or braking device for furniture or home appliances that ensures a safe coupling of an activator and a catch part with a compact configuration.

BRIEF DESCRIPTION OF THE DRAWINGS The invention will be described in more detail below with reference to several embodiments shown in the accompanying drawings. From here:
1a and 1b are two perspective views of a furniture component with an acceleration or braking device according to the invention;
Fig. 2 is an enlarged view of the acceleration or braking device of Fig. 1;
3 is an exploded perspective view of an acceleration or braking device;

Figures 5 to 9 are several views showing the acceleration or braking device in the event of a collision of the activator on the catch in a slightly modified embodiment;
Figures 10a and 10b are two views showing additionally modified acceleration or braking devices.

The furniture part 1 comprises a furniture body 2 having two side walls 3 , a floor 4 and a top panel 6 .

For movably mounting one or more sliding doors 8 , a guide rail 5 is fixed to the floor 4 , and a holding rail 7 is fixed to the top panel 6 .

The sliding door 8 is moved in the closing direction according to the arrow as shown in Fig. 1A, and is located in the closed position shown in Fig. 1B. It is also clear that two or more sliding doors 8 can be movably mounted on the furniture body 2 .

2 shows the floor area of a sliding door 8 , it can be seen that the sliding door 8 is held on a carriage 9 supported by one or a plurality of rollers on a guide rail 5 . .

In order to avoid hitting the sliding door 8 during the closing movement, an acceleration or braking device 10 is provided, which brakes the sliding door 8 just before reaching the closed position.

The damping device, which is shown for example by way of an acceleration or braking device 10 acting as a braking device, is shown in detail in FIGS. 3 to 10 .

The brake device 10 comprises a housing 11 which is fixed to the bottom area of the sliding door 8 .

A guide track 12 is formed on the housing 11 and has a linear section and an angled end section 13 .

The catch portion 14 is movably guided on the guide track 12 , and includes guide pins 15 protruding on both sides and movable in the guide track 12 .

The catch 14 further comprises a substantially U-shaped receiving means 16 having two sidewalls and a base used for coupling to the activator 21 .

The catch portion 14 is connected to an energy storage unit 17 in the form of a spring, and the energy storage unit has one end fixed to the housing 11 and the other end fixed to the catch portion 14 , , pretension the catch 14 to the end position relative to the angled end section 13 to move the sliding door 8 in the closing direction.

A damper with a damper housing 18 and a piston rod 19 is further fixed to the housing 11 , the piston rod being fixed to the catch 14 .

For this purpose, each connecting element 20 is provided on said piston rod 19 .

A damping fluid, such as oil, may be provided in the damper housing 18 , which is applied to the piston rod 19 by the piston to generate an efficient high damping force according to the load of the sliding door 8 . moved during insertion.

The activator 21 is fixed to the guide rail 5 , the activator being formed in a web-shaped manner, and held at the first end 22 via fastening means to the guide rail 5 .

A section 23 is provided on the opposite end and can be engaged with the catch 14 .

FIG. 4a shows the braking device 10 immediately after the activator 21 is coupled to the catch 14 .

The section 23 is held in one face on the contact surface 24 of the catch 14 .

At present, the catch 14 is pivoted by contact with the activator 21 out of the angled end section 13 so that the two guide pins 15 are arranged in a linear section of the guide track 12 .

If the sliding door 8 is moved through the carriage 9 with the roller 90 further in the current closing direction, the piston rod 19 travels inside the damper housing 18 so that a damping force is generated. .

This can cause large forces, especially in the case of heavy sliding doors 8 , and cause skipping of the catches 14 .

To avoid this problem, the contact surface 24 is not arranged perpendicular to the direction of movement of the driver 14 along the linear section, but is slanted, preferably arranged in an angular range between 4° and 20°.

The contact surface 24 is thus adapted to pivot the resilient section 23 of the activator 21 within the receiving means 16 to counteract potential skipping of the activator and increase functional reliability. For this purpose, it is useful when a large damping force is generated.

4b shows the pivoted position of the section 23', which is slightly pivoted in the receiving means 16 as a result of the large damping force.

Unlike FIG. 4a , the section 23 is no longer arranged in the longitudinal direction of the web-shaped activator 21 , but is slightly inclined, which means that the section 23 ′ is a contact surface in the receiving means 16 . This is because it moves according to (24).

The contact surface 24 is initially formed in a linear manner, then in a bent manner to limit the range of movement of the section 23'.

5 to 9 describe the damping process of the braking device 10 in detail.

The activator 21 is used and comprises, in addition to the end-side section 23 , a recess 29 into which a leg 26 can be inserted.

The legs 26 are arranged on one side of the receiving means 16 opposite the contact surface 24 .

Other than that, the braking device 10 corresponds to the above-described embodiment.

FIG. 5 shows the position in which the catch 14 is latched on the angled end section 13 of the guide track 12 .

For this purpose, a guide pin 15 is arranged on the angled end section 13 , the catch 14 being brought into the position shown on the right in FIG. 5 , despite the pulling force of the energy storage unit 17 . may not move.

In order to unlock the catch 14 in the first step, the section 23 of the activator 21, as shown in FIGS. 5, 6 and 7, is such that the catch 14 is pivoted in the first step. , hit on the contact surface 24 .

6 shows the unlocking procedure of the catch 14 , FIG. 7 shows that it has already been unlocked, and all guide pins 15 are located in a linear section of the guide track 12 .

After unlatching, the guide rod 19 is pressed into the damper housing 18 , and a damping force is generated to brake the respective movement between the sliding door 8 and the furniture body.

In this situation, the skip of the activator on the catch 14 is such that the contact surface 24 is inclined with respect to the direction of movement of the catch 14 along the linear section of the guide track 12, This is avoided, since it is preferably arranged at an angle between 4° and 20°.

As a result, the section 23 is pivoted into the receiving means 16 under a large damping force, as shown in FIGS. 7 and 8 .

Under a large damping force, the section 23 has a force component in the direction of the receiving means 16 , as a result of which the section 23 is pressed in the direction of the base of the receiving means 16 .

Thus, skipping is safely prevented.

When the sliding door 8 is decelerated, an energy storage unit 17 formed by a tension spring ensures that the catch 14 is moved to the closed position, and the legs 26 are arranged behind the section and thus pulling the sliding door 8 in the closing direction.

When the sliding door 8 is moved in the closing direction at a high closing speed, the section 23 is firstly pivoted into the receiving means 16 of the catch 14 as shown in FIG. 8 .

Accordingly, a small gap 30 is formed between the housing 11 and the guide rail 5 .

If, as a result of high speed, the sliding door 8 is lifted a little, in particular against the rollers 90 of the carriage 9 in front of the closing direction, the housing 11 is lifted in relation to the guide rail 5 . , the gap 30 ′ ( FIG. 9 ) is provided larger than the gap 30 without lifting of the sliding door 8 .

Even if, as a result of the inclined arrangement of the contact surface 24 and the pivoting of the section 23 of the activator 21 , a slight lifting of the sliding door 8 occurs, the section 23 is It is ensured that the coupling between the activator 21 and the catch 14 is maintained, as it is moved into the receiving means 16 as soon as it strikes the top, as a result of which the coupling exerts a damping force. It is not released even when lifting of the sliding door 8 by

10A and 10B show a modified embodiment, wherein, instead of an integral design, a plurality of partial combinations of activators 21' are inserted.

For this purpose, a modified end section 40 is provided to be rotatably mounted on the activator 21 ′ about an axis 41 .

As in the above embodiment, the end section 40 can strike on the catch 14 on the contact surface 24 , and the damping force is applied to the end section with respect to the axis 41 , as shown in FIG. 10b . (40) may occur after unlocking of the catch (14) to enable pivoting.

The end section 40 may be pretensioned by a spring in the position shown in FIG. 10A so that only pivoting is possible under actuation of a force by the contact surface 24 .

As a result of the inclined arrangement of the contact surface 24 in this embodiment, the impact force is at least partially absorbed by the pivotal movement of the end section 40, as a result of which the functional reliability is reduced by the catch of the activator 21' ( 14) is improved. Separately, this embodiment is designed as a brake device.

In this embodiment, the contact surface 24 is arranged in an inclined manner with respect to the direction perpendicular to the travel path of the catch 14 along the linear section of the guide track 12 .

The inclination of the contact surface 24 is not determined in the latching position, since the catch 14 is arranged in such a way that it pivots with a guide pin 15 on the angled end section 13 .

Instead, the inclination of the contact surface 24 is determined when the guide pin 15 is positioned along a linear section of the guide track 12, whereby the damper is pressed, in which case the required damping force is only generated. Because.

The above embodiment shows the use of a braking device as a damping device for a sliding door.

It is also clearly possible to provide the braking device 10 on the pull-out guide on the drawer, and the sliding door or drawer can be used not only for furniture but also for household appliances.

The commercial use of such devices in acceleration devices is also conceivable.

An accelerator device is to be understood as a drive device by which a movable component such as a sliding door or a drawer is made to be moved from a fixed initial position, for example after unlocking of a touch-latching fitting. .

The coupling between the activator and the catz part may be formed as in the above-described embodiment, and the movement of the movable component is accelerated and not braked.
