Description

  The present invention relates to an acceleration or braking device for furniture or household appliances, comprising a fastener that is moved along a guide track and has receiving means, into which a part of an active body can be inserted, the damper The fastener is moved along the guide track against this force, and the activity is applied to the contact surface of the fastener as it strikes the fastener.

  German Offenlegungsschrift 102012109752 discloses a discharge device with a drawer guide, which is equipped with an operating rail that can be moved with the active body. The activator is formed as a flexible lever and is inserted into the catch receiving means together with the protrusion to move the catch along the guide track. The fastener is coupled to a latch mechanism and the drawer is latched in the closed position. As a result of forming the active body as a flexible lever, the use of the damping device is not good with the mechanism shown, and there is a large impact force to decelerate the movable drawer element, in this case the fastener is This is because skipping occurs when pushed out of the fastener receiving means.

  In order to prevent such skipping, European patent 2401941 proposes guiding the fasteners along a guide track in a self-retraction mechanism and engaging the fasteners with the projections of the active body. The guide track for the fastener comprises a cover adjacent to the beveled end, which prevents the active body from performing a movement out of the fastener receiving means. The cover thus secures a connection between the fastener and the active body, but the cover requires additional mounting space.

Accordingly, it is an object of the present invention to provide an acceleration or braking device for furniture or household appliances that ensures a secure connection of the activity and fasteners in a compact configuration.
This object is achieved by an acceleration or braking device with the features of claim 1.

In the acceleration or braking device according to the present invention, when the fastener is movable along the guide track and the activity strikes the fastener, the activity is applied to the contact surface of the fastener, and the number of contact surfaces The section is oriented in an inclined manner with respect to the direction perpendicular to the direction of movement of the fastener, and the section of the active body is rotated into the receiving means when it hits the contact surface. The skipping of the activity on the fastener is thus prevented, because a force is intentionally generated when the activity strikes the fastener, which causes the section of the activity to rotate into the receiving means. , Prevent jumping out of the receiving means.
In addition to absorbing a certain amount of impact energy, the rotational movement of the active section also provides a secure connection of the fastener to the active body, which is particularly advantageous for high damping forces. Acceleration or braking devices are used in particular for sliding doors or drawers of furniture or household appliances, and malfunctions of the sliding elements are reliably prevented.

  The inclined area of the contact surface forms a sliding surface that rotates the active body in a specific range. According to a preferred embodiment of the invention, the inclination of the contact surface relative to the direction perpendicular to the direction of movement of the fastener is an angle between 4 ° and 30 °, in particular an angle between 6 ° and 20 °. The contact surface need not be formed in a linear shape, but is at least partially curved. When the activator strikes the contact surface, a force is generated by the tilt of the contact surface to ensure a predetermined amount of rotation of the activity into the receiving means, the magnitude of the rotational movement being dependent on the damping force. The rotation path is therefore in particular in the range between 0.1 mm and 5 mm, in particular in the range between 0.5 mm and 3 mm, and the contact surface forms a sliding surface for the fastener. The contact surface is provided with a regulating stopper or non-tilted section to regulate the rotation path of the active body.

  The receiving means is preferably generally U-shaped and comprises two side walls and a base. A contact surface is formed on the side wall of the receiving means, and the end section rotates relative to the base of the receiving means when the active body hits the contact surface.

  The active body is on the contact surface and is oriented to tilt with respect to a direction perpendicular to the direction of movement of the fastener. The impact force is distributed over such a large surface area so that the tilt of the active surface on the contact surface is equal to the tilt of the contact surface when the driver is moved along the linear section of the guide track. Selected. The inclination of the surface relative to the direction perpendicular to the direction of movement of the fastener is an angle between 4 ° and 30 °, in particular an angle between 6 ° and 20 °.

  The contact surface of the fastener and / or the surface on the active body in contact with the contact surface can be roughened by suitable means or coating, or can be slid to allow a change in the friction value of the two surfaces as desired. It is also possible to apply a coating.

  In a further embodiment, the activity is formed in a web shape and is secured on the opposite side of the section for connection with a fastener. The active body forms a lever between the fixing point and the section connected to the fastener, the lever having a length between 1 cm and 8 cm, in particular between 3 cm and 6 cm. The activators are preferably oriented generally parallel to the direction of movement of the fasteners and only require very little mounting space perpendicular to the direction of movement. The direction of movement of the fastener is parallel to the running rail of the sliding door or drawer guide.

  The fastener guide track is generally linear and includes at least one inclined end section to which the fastener is latched. As a result, the fastener is rotated, and after the impact on the contact surface of the activator, the latch on the inclined end section is released, and the lock is released in the first stage to The relative movement between the guide tracks is braked by the movement of the fasteners. A damper, in particular a linear damper, is preferably used for this purpose, and the damper provides a sufficient damping force for each purpose. Each damper works in particular with oil as a fluid damper and is moved in the damper housing by a piston.

  The acceleration or braking device according to the present invention can in particular be used in a sliding door fitting, for example on the bottom side of a sliding door, to brake the closing movement. The guide track is formed on a housing fixed to the sliding door, and the activity body is fixed in a stationary state on the furniture or household appliance. It is also possible to fix the activity body to the sliding door and apply the housing provided with the guide track on the furniture body in a stationary state.

The present invention will be described in more detail with reference to several embodiments shown in the accompanying drawings.

The elements of the furniture 1 comprise a furniture body 2 comprising two side walls 3, a bottom 4 and a top panel 6.
A guide rail 5 is fixed to the bottom 4 and a holding rail 7 is fixed to the top panel 6 to displaceably attach one or several sliding doors 8.
The sliding door 8 is moved in the closing direction of FIG. 1A according to the arrow and is located at the closing position of FIG. 1B. Two or more sliding doors 8 are clearly displaceably mounted on the furniture body 2.

  FIG. 2 shows the bottom area of the sliding door 8 and it can be seen that the sliding door 8 is held on a carriage 9 supported on the guide rail 5 by one or more rollers. In order to prevent the sliding door 8 from being hit during the closing operation, an acceleration or braking device 10 is provided that brakes the sliding door 8 immediately before reaching the closed position.

  The damping device illustrated by the example of the acceleration or braking device 10 and acting as a braking device is shown in detail in FIGS. The brake device 10 includes a housing 11 that is fixed to the bottom region of the slide door 8. A guide track 12 is formed on the housing 11, and the guide track includes a linear section and a sloped end section. The fastener 14 is guided displaceably on the guide track 12, and the fastener includes guide pins 15 that protrude from both sides and are displaceable on the guide track 12.

  Fastener 14 further includes a base that is used to be connected to a generally U-shaped receiving means 16 with two side walls and an active body 21. The fastener 14 is connected to an energy storage unit 17 in the form of a spring, the spring having one end secured to the housing 11 and the other end secured to the fastener 14, which spring attaches the fastener 14. The end position is pretensioned with respect to the inclined end, and the slide door 8 is moved to the closed position.

  A damper including a damper housing 18 and a piston rod 19 is further fixed to the housing 11, and the piston rod is fixed to the fastener 14. Individual connection elements 20 are applied to the piston rod 19 for this purpose. Damping fluid, such as oil, is applied in the damper housing, and the damping fluid is moved by the piston when the piston rod 19 is inserted, and generates a sufficiently large damping force due to the weight of the sliding door 8.

  The active body 21 is fixed to the guide rail 5, the active body is formed in a web shape, and the first end 22 is held on the guide rail 5 by a fixing means. The opposite end is provided with a section 23 that can engage the fastener 14.

FIG. 4A shows the brake device 10 immediately after connecting the active body 21 to the fastener 14. Section 23 is located on contact surface 24 of fastener 14 and contact surface 24 is formed on the sidewall. The fastener 14 is pivoted from the end section 13 which is tilted in contact with the active body 21 and two guide pins 15 are arranged in the linear section of the guide track 12. When the sliding door 8 is further moved in the closing direction by the carriage 9 provided with the roller 90, the sliding door 8 is further moved in the closing direction by the carriage 9 provided with the roller 90, and the piston rod 19 generates a damping force. So as to move into the damper housing 18.
This leads to a high force, in particular in the case of a heavy sliding door 8, a high force that leads to skipping of the fasteners 14. In order to prevent this effect, the contact surface 24 is not oriented perpendicular to the direction of movement of the driver 14 along the linear section, but is inclined with respect to the direction of movement and in an angular range between 4 ° and 20 °. Preferably there is. The contact surface 24 is used in the case of such a high damping force and rotates the resilient section 23 of the active body 21 into the receiving means 16, preventing the possibility of active body skipping and functional Increase confidence.

  FIG. 4B shows the rotated position of the section 23 ′ and has been rotated slightly into the receiving means 16 as a result of the high damping force. In addition to FIG. 4A, the section 23 is no longer oriented in the longitudinal direction of the web-shaped active body 21 but is slightly inclined with respect to the longitudinal direction, because the section 23 ′ is received along the contact surface 24. This is because it has been moved into the means 16. The contact surface 24 is initially formed in a line shape and then bent to limit the range of movement of the section 23 '.

  5 to 9 describe the damping process of the brake device 10 in detail. An activator 21 is used, which comprises a recess 29 in addition to the end section 23, into which a leg 26 can be inserted. The leg 26 is arranged on one side of the receiving means 16 facing the contact surface 24. Apart from that, the brake device 10 corresponds to the previous embodiment.

  FIG. 5 shows the position where the fastener 14 is latched onto the inclined end section 13 of the guide track 12. The guide pin 15 is arranged on the end section 13 inclined for this purpose, and the fastener 14 cannot be displaced to the position shown on the right side in FIG. 5 despite the traction of the energy storage unit 17. To remove the fastener 14 in the first stage, as shown in FIGS. 5, 6 and 7, the section 23 of the active body 21 abuts the contact surface 24 and the fastener 14 is rotated in the first stage. Fastener 14 is shown in the removal procedure of FIG. However, already removed in FIG. 7, both guide pins 15 are located in a linear section of the guide track 12.

After the latch is released, the piston rod 19 is pushed into the damper housing 18 and a damping force is generated to brake the relative movement between the sliding door 8 and the furniture body.
In this situation, the contact surface 24 is oriented on the fastener 14 in that it is oriented at an angle preferably between 4 ° and 20 ° with respect to the direction of movement of the fastener 14 along the linear section of the guide track 12. Activator skipping is prevented. As a result, as illustrated in FIGS. 7 and 8, section 23 is rotated into receiving means 16 under a high damping force. Under a high damping force, the section 23 receives a component force in the direction of the receiving means 16 and the section 23 is pressed in the direction of the base of the receiving means 16. Skipping is thus safely prevented.
When the sliding door 8 is decelerated, the energy storage unit 17 formed as a tension spring moves the fastener 14 to the closed position and the leg 26 is placed behind the section 23, thus the sliding door 8. It is certain to pull in the closing direction.

When the sliding door 8 moves in the closing direction with a fast closing speed, the section 23 is rotated into the receiving means 16 of the fastener 14 in the first stage, as shown in FIG. A small gap 30 is formed between the housing 11 and the guide rail 5.
As a result of the fast speed, the housing 11 is lifted with respect to the guide rail 5 and lifts the sliding door 8 when the sliding door 8 is lifted slightly, especially around the roller 90 of the carriage 9 forward in the closing direction. Instead, a gap 30 ′ (see FIG. 9) larger than the gap 30 is generated. As a result of the tilted orientation of the contact surface 24 and the rotation of the section 23 of the active body 21, it is ensured that the connection between the active body 21 and the fastener 14 is maintained even if the sliding door 8 is lifted slightly. As a result, even when the sliding door 8 is lifted by the damping force, the coupling is not released.

FIGS. 10A and 10B show a modified embodiment in which the activity 21 ′ is inserted, with multiple sub-configurations instead of the essential configurations. For this purpose, a modified end section 40 is provided which is mounted for rotation about an axis 41 on the active body 21 '. The end section 40 abuts the fastener 14 on the contact surface 24 as in the previous embodiment, and a damping force is generated after the fastener 14 is released, and the end section about the axis 41 as shown in FIG. 10B. Ensure 40 rotations. The end section 40 is pretensioned to the position of FIG. 10A by a spring and rotates only under the action of a force by the contact surface 24.
Also in this embodiment, as a result of the contact surface 24 being tilted, the impact force is at least partially absorbed by the rotational movement of the end section 40 and the functional reliability is the activity 21 to the fastener 14. Improved by combining '. Apart from that, this embodiment is formed like a brake device 10.

In the illustrated embodiment, the contact surface 24 is oriented inclined with respect to the orthogonal direction of the travel path of the fastener 14 along the linear section of the guide track 12. The inclination of the contact surface 24 is not determined in the latched position because the fastener 14 is arranged in rotation with respect to the guide pin 15 on the inclined end section 13.
Instead, when both guide pins 15 are oriented along the linear section of the guide track 12, the inclination of the contact surface 24 is determined, because the damper is compressed and the required damping force is only at this time. This is because it is generated.

In the embodiment shown, the use of a brake device as a damping device in a sliding door is shown. It is obviously also possible to apply the brake device 10 to the drawer's drawer guide, and the sliding door or drawer can be used for both household appliances and furniture.
Furthermore, the use of this device in an acceleration device is also conceivable. The acceleration device is understood to be a drive device, so that a movable element, such as a sliding door or drawer, moves from its initial position, for example after release of the contact latch fit. Made. The connection between the activator and the fastener is formed as in the above embodiment, the movement of the movable element is accelerated and not braked.
