Definitions
- the present invention relates to an ejection device for a movable furniture part, in particular a drawer or a door, with a driver which can be moved between two end positions along a guide track formed on a housing, the driver being in a first end position on one by an energy store angled end portion of the guide track is biased, and the driver can be coupled to an activator when moving along the guide track, the coupling of the driver can be decoupled from the activator when moving into the angled end portion, and a locking mechanism is provided by means of which the driver can be latched in a second end position with a tensioned force storage device, the latching mechanism being able to be locked at least by moving the driver in one direction against the force of the energy storage mechanism.
- EP 2 445 376 B1 discloses a self-closing device for a pull-out guide in which a driver can be moved along a link guide on a housing.
- the driver is guided over guide webs on the Ku lissen Installation and engages around a guide web on the housing with a clamping nose.
- the link guide has an angled end section in order to decouple the driver from an activator and to fix it to the angled end section with a tensioned energy store. From this position, the energy storage device can then pull the driver into a closed position.
- the highest forces arise with such a self-retracting device when the activator hits the driver and is wasted from the parking position. Therefore, the driver is secured in this area by a clamping lug against lifting off the housing.
- the forces occurring in the Doweinzugsvor direction are not comparable to an ejector in which the driver is pretensioned in the opposite direction, namely in the direction of the angled end portion.
- EP 2 266 437 B1 discloses an opening device for a pull-out guide, in which a driver can be moved on a guide housing and has guide elements on opposite sides which engage in two guide tracks.
- the bilateral guidance of the driver makes it difficult to access the driver through an activator.
- the mon days of the driver and the ejector device are more complex, since the driver cannot simply be placed on the guideway.
- a driver can be moved between two end positions on a guide track, the driver in the end position on the angled end portion of the guide track by at least one securing means formed integrally with the housing against lifting off the housing orthogonally or almost orthogonally to the direction of movement of the Driver is secured.
- the driver can be held securely to the housing and the guide track in this end position, even if the driver is acted upon via an energy storage device, which, without being secured by the securing means, could lever the driver off the guide track by tilting or pivoting .
- the driver is thus at least securely held on the housing despite the bias by the energy storage device.
- the driver is preferably secured against being lifted off the housing by at least two securing means arranged at a distance from one another on the housing.
- the driver is predominantly held in a form-fitting manner on the securing means.
- the safety means are designed as projections which overlap contact surfaces designed on the driver. The two projections can act on different sides of the driver, in particular on opposite sides, in order to secure the driver against lifting.
- the securing means on the housing can be designed as a pocket, clearance or flea space, into which the corresponding projections on the driver engage positively.
- a run-on bevel is formed on the driver and / or the min least one projection on the housing, which presses the driver towards the housing in the first end position.
- the run-on slope can thus be used to move the driver to the housing to pretension and even better to secure it against lifting off the housing.
- the run-up bevel can either be formed on only one or more projections, only on one contact surface of the driver or on both.
- the driver is preferably designed in the form of a plate and is provided on one side with at least one guide element which engages in the guide track.
- a receptacle for the engagement of an activator is provided on the opposite side.
- the guide track can be formed in the shape of a groove or slot, preferably two peg-shaped guide elements on the driver engaging the guide track.
- the driver can be pivoted in a predetermined path when it hits the angled end section in order to decouple the activator from the driver.
- the driver is preferably designed in one piece, but can also be composed of several components.
- a guide web is preferably formed at a distance from the Füh approximately track, which is gripped by a guide portion of the driver.
- the contour course of the guide web follows that of the guide track, whereby a linear section and an adjoining angled end section are formed.
- This guide section can encompass the guide web in a U-shape in order to secure the driver against lifting off the guide track.
- the U-shaped encompassing of the guide bar does not necessarily have to take place in a single plane perpendicular to the travel direction of the driver, but can be done through different sections that are offset from one another in the travel direction of the driver. This facilitates the free position and assembly of the driver.
- Fer ner can be provided on the guide web at least one recess for mounting the driver, which is arranged in a central area of the travel path of the driver. As a result, the driver can also be easily attached to the housing in an automated process.
- At least one of the projections formed on the housing is preferably arranged in an extension of the linear section of the guide web.
- the ejection device has a latching mechanism which comprises a control element connected to the driver, which is guided in a control cam with a latching receptacle.
- control curves are known per se and are also referred to as Flerz curve, since a loop-shaped section of the curve guide is designed in the form of a Flerz and the control element can be locked in this area on the locking receptacle.
- the control element can have a bent wire that is connected to the slave on one side and is guided on the opposite side with a bent end portion in the control cam.
- the control cam for the locking mechanism can be formed on a cover that is fixed to the housing, for example via a locking connection.
- the ejection device can be manufactured with only a few components.
- this cover can also cover other components, such as, for example, energy storage devices, synchronization means and the like, and protect them against access.
- the energy store of the ejection device is connected to the driver via a plunger, a contact surface of the driver being arranged for engagement with a projection on the housing in extension of the plunger when the driver is arranged on a linear section of the guide track. This ensures that the forces introduced into the driver by the force storage device can essentially be introduced into the housing through the contact surface and the projection.
- the ejection device according to the invention is used in particular in a piece of furniture or a household appliance that has a movable furniture part, such as a drawer. But it is also possible to use the ejection device for a sliding door, a pivoting door or other movable furniture parts, the movable furniture part in the sense of the present application can also be part of a household device.

- FIG. 3 shows a view of a pull-out guide of the furniture in FIG. 2 with an ejector device
- FIG. 4 shows a view of the ejection device of FIG. 3 without
- FIG. 5 shows a view of the ejection device of FIG. 4 in an open state
- FIG. 6 shows a view of the ejection device of FIG. 5 with the cover rotated
- FIG. 7 shows a detailed view of the driver of the ejection device in an end position
- FIGS. 8A to 8C show several views of the ejection device of FIG. 4, partly in section;
- FIG. 9 shows a view of the ejection device without a driver
- FIG. 10 shows a view of the ejection device of FIG. 9 with entrainer
- Figure 1 1 is a view of the ejection device of Figure 10 with the cover removed.
- a piece of furniture 1 comprises a furniture body 2 on which several drawers 3 can be moved.
- pull-out guides 4 are provided in the furniture carcass 2, which are fixed to the furniture carcass 2 via an angular holder 5 and have a movable rail 6 for moving the drawer 3 (FIG. 2).
- An activator 7 in the form of a projection is fixed on the movable rail 6 and can engage with a driver of an ejector device 8.
- Such an ejector device can be latched in a substantially closed position of the drawer 3.
- the drawer 3 is then pressed against the force of an energy storage device into the furniture body 2 into an overpressed position in order to unlock the locking mechanism, so that after the unlocking of the Drawers 3 can be thrown out by the force of the energy store in the opening direction.
- a pull-out guide 4 is shown, in which a housing 9 of the pushing device 8 is fixed to the holder 5.
- the activator 7 protruding from the movable rail 6 is coupled to a driver 10 which can be moved along a guide track on the housing 9.
- Such ejection devices 8 can also be coupled or synchronized with one another, so that when an ejection device is unlocked, a further ejection device is unlocked at the same time or with a time delay.
- Such synchronization devices are shown, for example, in DE 10 2016 113 577, to which reference is hereby made and which can also be used in the present Ausoßvor direction.
- the ejection device 8 is shown without a pull-out guide 4.
- the ejection device 8 comprises an essentially shell-shaped housing on which a groove-shaped guide track 11 is formed, into which one or more guide elements of a movable driver 10 engage.
- the driver 10 comprises a receptacle 12 which has stops on opposite sides and into which a projection of the activator 7 can engage so that the driver 10 can only be moved together with the activator 7 and is coupled to it.
- the driver 10 is pretensioned by an energy storage device in a first end position on the guide track 11, the energy storage mechanism acting on the driver 10 via a plunger 15. In the opposite, second end position with the tensioned force storage, the driver 10 can be locked via a control element 16.
- the ejection device is shown with a removed cover 17 which covers part of the housing 9. It can be seen that an energy store 18 in the form of a compression spring is fixed on the housing 9, which is supported on one side on the housing 9 and on the opposite side on a web of the plunger 15, around the plunger 15 towards the driver 10 pre-tension.
- the driver 10 is located at an angled end portion of the guide track 11 and is fixed to the housing 9 in a form-fitting manner via two securing means, the projections 14 and 25 and secured against lifting.
- a control element 16 is connected to the carrier 10, the control element 16 from a curved Wire is made and on one side reaches through an opening on the driver 10 via a hook 24.
- the control element 16 On the opposite side, the control element 16 has a bent end portion 60 which engages in a control curve 19 on the cover 17 and is movable there.
- the control cam 19 is designed as a "heart cam” and has a latching receptacle in which the end section 60 of the control element 16 can latch when the force accumulator 18 is tensioned when the driver 10 is in the second end position opposite the angled end section.
- This locking by the control element 16 can be unlocked in that the driver 10 is pressed slightly against the force of the energy storage device 18, in order then to be ejected by the energy storage device 18.
- the control cam 19 is formed integrally with the cover 17, which is connected to the housing 9, preferably by locking.
- the control cam 19 can alternatively also be formed on the housing 9.
- the driver 10 has been placed or pushed onto the guide track 11 of the housing 9 and is secured against lifting off the housing 9 in the first end position at the angled end section.
- a first projection 14 is formed integrally with the housing 9, which forms a stop for a contact surface 13 formed inclined on the driver 10.
- the contact surface 13 is designed as a bevel so that the load on the energy storage device 18 not only blocks the driver 10, but also pushes it towards the housing 9 due to the inclined arrangement of the contact surface 13.
- another projection 25 is formed on the Ge housing 9, which protrudes towards the driver 10 and overlaps a web 26 which is formed on an opposite side of the contact surface 13.
- the projection 25 prevents the web 26 from lifting.
- the driver 10 is also held by a guide web 20 on the housing 9, the guide web 20 being gripped under by a nose 22 on the driver 10 and overlapped by two guide sections 23 on the driver 10.
- the guide web 20 is thus encompassed by the shape of the driver 10 in a U-shape, the reaching over and under does not take place in a single plane along the direction of travel, but offset from one another in the direction of travel. This nevertheless leads to securing of driver 10 against lifting from the housing and to improved guidance.
- FIGS. 8A to 8C the housing 9 and the driver 10 are shown in different details. It can be seen that the control element 16 and the plunger 15 are net angeord on opposite sides of the guide track 11.
- the driver 10 is located on the angled end section of the guide track 11, which in addition to this angled end section has a linear section adjoining it.
- the contour of the guide web 20 corresponds in its longitudinal extension to that of the guide track 11, so that a linear section and an angled end section are also formed here.
- a projection 14 is arranged in an extension of the linear section of the guide web 20 on the housing 9.
- the guide web 20 comprises a recess 21 in a central area of the travel path of the driver 10, which facilitates assembly and disassembly, since the driver 10 can simply be plugged onto the housing 9 in the region of the recess 21.
- FIG. 8B it is shown that the guide web 20 is framed in a U-shape by the nose 22 and the guide sections 23. Furthermore, the groove-shaped Füh approximately track 11 is shown in which a pin-shaped guide element 27 on the driver 10 is partially visible. Two guide elements 27, which are spaced apart from one another, are formed on the driver 10.
- a protruding hook 90 is also integrally formed on the housing 9, by means of which the housing 9 can be mounted on a further component, such as a rail of a pull-out guide 4.
- the housing 9 of the ejector 8 is shown without driver 10 GE. It can be seen that the guide track 11 is linear and has an angled end section 28 only at one end.
- the Füh approximately web 20 extends, as already described, parallel to the guide track 11 and only additionally has the recess 21 for mounting the with carrier 10, which can be attached perpendicular to the guide track 11 plane.
- the driver 10 which is connected to the control element 16 and the plunger 15, is also shown.
- the projections 25 and 14 partially overlap the driver 10.
- FIG. 11 shows the ejection device with the cover 17 removed and rotated so that the control cam 19 on the cover 17 is visible.
- the control cam 19 is used to guide the control element 16, with a locking receptacle for locking the control element 16 being formed on the control cam 19.
- the latching receptacle can be designed in several parts, part of the latching receptacle being pretensioned by a spring 30 into an initial position. As a result, an additional securing function can be created in order to unlock the end section 60 from the latching receptacle in a different way, for example a synchronization.
- the ejection device 8 is provided on a pull-out guide 4 in order to hold a drawer 3 on the furniture body 2 via a push-to-open fitting. It is also possible to use the ejection device for other pushing elements, such as sliding doors, or for pivoting doors or flaps. List of reference symbols
