The activator (5, 5', 5", 5'", 5"") and/or the curve guide (7, 7", 7", 7'", 7"") can be moved both in a first direction and in an opposite second direction to release the driver (11, 11', 11", 11'", 11"").

Description

The present invention relates to an ejection mechanism, in particular for movable furniture parts, with a curved guide, along which a driver is movable, wherein the driver is biased by at least one energy storage in one direction and can be latched to the cam guide with tense energy storage in a closed position, and a with the driver at least in the closed position coupled activator, wherein the activator relative to the cam guide or the cam guide is movable relative to the activator, wherein in the closed position of the driver via a Reiativbewegung the activator relative to the cam guide or a relative movement of the cam guide relative to the activator can be unlocked and a pullout guide and a discharge system.

EP 1 845 821 discloses a device for opening and closing drawers in which the drawer is held in a closed position by means of a latching mechanism. The latching mechanism comprises a driver which can be coupled to a running rail, on which a rod is arranged, which is guided in a control cam. To unlock the drawer against the

Pressed force of a spring, so that then the rod is released from the latched position in the control cam and can be moved together with the driver and the track rail. In such a device for opening and closing is disadvantageous that the unlocking of the locking mechanism is effected only by a depression of the drawer. In addition, the locking is done by a variety of components that can absorb only limited mechanical stress, άa they are filigree and damage is expected. It is therefore an object of the present invention to provide an ejection mechanism and a pullout guide, which is sturdy and allows easy unlocking of a driver.

This object is achieved with an ejection mechanism having the features of claim 1. According to the invention, the driver is entriegeibar in the Schiießposition via a relative movement of the activator, wherein the activator and / or the cam guide for unlocking the driver in both a first direction and an opposite second direction is movable. This can take place both by a pulling movement on the movable furniture part as well as by pressing the movable furniture part unlocking. The user thus has the option of how the ejection mechanism is unlocked. If the movable Möbelteii is fixed to a pullout guide, either the cam guide or the activator can be movable while the other component is arranged stationary. Due to the relative movement between

Curved guide and activator unlocking is effected by appropriate mechanical means. Further, the handling of the ejection mechanism is simple, with the respective components stably formed and the number of components reduced as compared with prior art solutions.

According to one embodiment, the driver from the closed position by the relative movement between the activator and the cam guide is pivotable. Thereby, the cam guide may be formed as a guide device in which the driver is movable in opposite directions. It is not necessary to provide a loop-shaped guideway with a detent recess since the latching can take place at a bent end section of the guideway. By pivoting the driver this can be unlocked from the angled end portion and transferred to the linear section, in which the energy storage provides for an opening movement.

Preferably, the activator has a first abutment surface for unlocking the driver by movement in the first direction and a second abutment surface spaced from the first abutment surface for unlocking the driver by movement in the second direction. Thereby, the activator can also be integrally formed, wherein from the closed position regardless of the

Movement direction a Entriegein the driver can be done.

For a stable guidance of the driver, this has two spaced-apart pins, which engage in the groove-shaped curve guide. In this case, the cam guide may have at least one bent end portion, on which the driver can be latched in the closed position.

The activator can embrace the driver substantially U-shaped in order to form on the two legs of the US each have a contact surface, the Carrier unlocked. Alternatively, it is possible to form the driver as a hook, wherein the activator on opposite sides of the hook has a contact surface for unlocking the driver. Preferably, at least one lever which can be moved by the activator and / or the cam guide is provided, by means of which the driver can be unlocked. As a result, a reliable unlocking can be ensured, wherein the lever is rotatably mounted, for example, on the housing with the cam guide. To unlock the driver by the lever, the driver can be coupled with play with the activator or the activator is also movably mounted, in particular resiliently and / or rotatably mounted to ensure movement to the starting position.

According to the invention, a pull-out guide is also provided with a guide rail which can be mounted on a furniture body and a movably mounted running rail, which has an ejection mechanism according to the invention.

In order to facilitate the assembly of the pullout guide with the ejection mechanism, the activator can be adjustably fixed in the direction of movement of the running rail on the running rail. As a result, tolerances can be compensated to tune the position of the activator exactly to the desired closed position. The pullout guide can be designed as a preassembled unit, wherein the cam guide is fixed to the guide rail. According to one embodiment, an elastic stop is provided to the

Keep track with the activator in the closed position. The stop then ensures that the activator is positioned in the closed position, so that it does not accidentally unlock when it moves beyond the closed position. Furthermore, a damper may be provided to decelerate the track before reaching the closed position. This elastic stop can be made adjustable in the extension direction.

A use of an ejection mechanism according to the invention and a corresponding pullout guide in household appliances such. in ovens, in refrigerators and / or freezers, in warming drawers is also conceivable.

According to the invention, there is also provided an ejection system comprising first and second ejection mechanisms interconnected by a movable furniture member. Each ejection system can be attached to a be mounted leadership, the drawer guides via a Schubeiement, such as a drawer, are interconnected.

Preferably, the ejection system is designed so that when unlocking the driver of the first ejection mechanism and the driver of the second ejection mechanism is unlocked from the latched closed position. This ensures synchronization, which is necessary especially for wide drawers, since it may happen in an off-center force introduction to the opening of the drawer that only one ejection mechanism is unlocked on a drawer side. Should such a one-sided unlocking take place, is in the

Ejection system applied via the unlocked driver and the power storage a force in the opening direction, which then acts on the second driver over the furniture part and the second pullout guide and pulls it from the unlocked position in the opening direction. As a result, incorrect operations can be reliably avoided.

According to the invention, a pawl is arranged spaced from the activator according to claim 18, wherein the pawl can pass the catch in an opening direction and in the opposite closing direction, the pawl is engageable to move the catch in the closing direction. As a result, the ejection mechanism can be tensioned by the pawl even before the closed position, which also allows the use of a self-closing mechanism, which pulls the activator into a closed position after the driver has been tensioned. For driving over the driver of the ejection device, the activator and / or the pawl, for example, perpendicular to the opening direction slidably or pivotally about a pivot point can be performed. Alternatively, the driver may have spring-mounted levers which allow the activator to pass over in each case in one direction and come to rest in the opposite direction on the actuator and prevent it from being driven over.

An evasion of the activator or the driver is by a

translatory movement, rotational movement, curved movement, pivoting and / or by elastic behavior due to the selected ma- materials of the contact areas conceivable. Optionally, the complete activator or pawl or the driver deviates, alternatively, a partial evasion of individual components is possible. The counterforce to the return movement of the movable part can be applied by spring force, by elastic deformation, in particular of subcomponents. The previously described Ef - - effects can also be achieved by means of a design according to a directional locking mechanism, switching inhibitor or snap-action switching mechanism.

The activator or the Kiinke can be guided linearly in slots, for example. In this embodiment, the activator or the Kiinke can be reset by gravity or spring loaded in the starting position. The activator or pawl may alternatively be equipped with moving parts. These pawls or moving parts can be controlled via cam guides, by gravity, by using elastic material or spring force to return to the starting position.

The driver preferably has two spring-loaded counter-acting pawls or levers which allow both a force application and a low-power driving over. These pawls have a restoring moment that, for example, by elastic deformation of an underlying element is achieved. This element has two sections, each section being associated with a pawl. An embodiment as a rocker or leaf spring is also conceivable. The pawls can only be overrun in one direction. This functionality is required in particular when a multiple-action activator or several activators or pawls are used to control various devices. The pawls can be elastic, provided as a film hinge or with a storage.

To avoid false tripping, the triggering lever may be spring loaded to pressure in its home position. In the sense of a jump gear so a defined release force can be set. Only when crossing this

Force the driver is completely brought from its rest position in the bent end portion of the cam guide. The ejection mechanism is thus activated. In a cam-controlled system, the achievement of the open end position can be supported by an additional energy storage on the activator. Thus, a malfunction or damage to the modules, in particular in a deviating from the embodiment installation position, prevented. The invention will be explained in more detail below with reference to two embodiments with reference to the accompanying drawings. Show it:

An inventive ejection mechanism is mounted on a pullout guide 1, which has a mountable on a furniture body guide rail 2 and a movable running rail 3. Optionally, located between the guide and running rail an aussverlängernde center rail to allow a full extension. It is also possible to mount the ejection mechanism on a pivotable furniture door or another movable furniture part.

The ejection mechanism comprises an activator 5 fixed to the running rail 3, which is arranged in a closed position on a housing 6 with a cam guide 7. In the cam guide 7, a driver 11 is guided by designed as a tension spring force accumulator 8 is biased in the opening direction. The energy accumulator 8 is held at one end to a holder 9 fixed to the guide rail 2 and to the driver 11 on the opposite side.

In the closed position, a web 30 arranged on the running rail rests against an elastic stop 31, which is designed, for example, as a rubber buffer. The stop 31 is fixed to a holder 32 which is arranged on the guide rail 2 or a middle rail 13. The holder 32 can be made adjustable in the direction of extension.

As shown in Figures 2 to 6, two spaced pins 10 and 12 are provided on the driver 11, which are guided in the cam guide 7. The cam guide 7 has a middle linear portion including an angled end portion 70 in the opening direction and an angled portion 71 in the closing direction. In the area of the end sections 70 and 71, the driver 11 is pivoted away from the running rail 3. The driver 11 has a receptacle 14, in which the activator 5 engages with two webs 16 and 17. When the webs 16 and 17 engage in the receptacle 14, activator 5 and driver 11 move together.

In Figure 7, the Aktävator 5 is shown in detail. The activator 5 is essentially U-shaped and comprises three webs 15, 16 and 17 on one leg, wherein the webs 16 and 17 engage in the receptacle 14 on the driver 11. On the second leg of the activator 5, an inwardly directed projection 18 is formed, which can also come into contact with the driver 11. On the activator 5, a slot 19 is further provided, which is penetrated by a screw 20 to fix the activator 5 to the running rail 3. Through the slot 19, the activator 5 is adjustably held in the longitudinal direction of the running rail 3. In Figures 8A and 8B, the track 3 is shown in an open position. The activator 5 is arranged at a distance from the driver 11 and the driver 11 is moved by the force of the energy accumulator 8 into an end position in which the journal 10 engages in the end portion 70. As a result, the driver 11 is in a slanted position, in which the receptacle 14 for the engagement of the webs 16 and 17 of the activator is open. If the activator 5 is closed by shooting a drawer arranged on the slide rail 3, the activator 5 engages with the webs 16 and 17 in the receptacle 14 of the driver 11 and moves it against the force of the energy accumulator 8 in a closed position, as shown in the Figures 9A and 9B is shown. In the closed position, the pin 12 has been moved along the guideway 7 and engages in the end portion 71 a. As a result, the driver 11 has been pivoted downwards and is now fixed in a closed position by the force of the energy accumulator 8. As shown in FIG. 9B, the lower projection 18 abuts against the activator 5 on an abutment face 21 of the carrier 11. In addition, according to Figure 6, the web 16 adjacent to the Anlagefiäche 22 at the

Driver 11 is arranged.

In the closed position, the driver 11 can now be unlocked by movement of the activator 5, wherein the activator 5 can be selectively moved in the opening or closing direction. If the activator 5 is pulled in the opening direction, the web 16 engages the contact surface 22 and pulls the driver 11 into the rectilinear part of the cam guide 7, so that the driver 11 is unlocked. If the activator 5 is pressed in the closing direction, the projection 18 bears against the contact surface 21 and thereby pivots the driver 11 into the rectilinear part of the cam guide 7. An unlocking of the driver 11 from the closed position thus takes place, regardless of whether the activator 5 is moved in the opening or closing direction. The movement in

Closing direction for unlocking the driver 11 may be in a range between 1 to 3 mm, so that the resilient stopper 31 is compressed by the impressions.

FIG. 10 shows a second exemplary embodiment of a pullout guide V, which has an ejection mechanism according to the invention. As in the first embodiment, a running rail 3 is movably held on a guide rail 2, wherein the closed position of the running rail 3 is predetermined by a resilient stop 31 on which a web 30 of the running rail 3 is applied.

The ejection mechanism comprises a housing 6 ', in which a cam guide T is formed, which has only one angled end portion 70. The driver 11 'is held by two spaced pins 10 and 12 in the cam guide T. When the pin 12 is moved in the angled end portion 70 (Figure 12), the driver 11 'in a latched position and is through the force of the trained as a tension spring force accumulator 8 'biased in the opening direction.

To unlock the driver 11 'is an activator 5 ^! provided, which is fixed via a screw 20 'on the guide rail 2. The activator 5 'comprises a first projection 16', which rests against an inner side of a hook 22 'of the driver 11'. On the opposite side of the hook 22 'is a contact surface 21' is formed, which can engage with a run-on slope 18 'of the activator 5'.

In Figure 13, the driver 11 'by pressing the running rail 3 in

Schiießrichtung unlocked, in which case a relative movement between the cam guide T and the activator 5 'takes place. By the projection 16 ', a force is transmitted to the downwardly directed hook 22' of the driver 11 ', so that the pin 12 is pushed upwards and is displaced into the rectilinear portion of the cam guide 7'. As a result, the force accumulator 8 'is effective and pulls the driver 11' in the opening direction.

An unlocking of the driver 11 'can also be effected by movement of the cam guide 7' on the running rail 3 in the opening direction, in which case the run-on slope 18 'on the activator 5' in engagement with the contact surface 21 'on the hook 22' of the driver 11 'passes. Also by the pin 12 is pushed up into the rectilinear portion of the cam guide T. In Figures 15A and 15B, the pullout guide is shown in an open position with the activator 5 'spaced from the cam 11'. The driver 11 'is located in an end position of the cam guide T. When the track 3 is moved in the closing direction, engages the downwardly directed hook 22' between the projection 16 'and the Aniaufschräge 18' of the activator 5 ', so that upon reaching the closing position, the arrangement shown in Figure 12 is reached, from which the driver 11 'can be unlocked again.

FIG. 16 shows an ejection system which is mounted on a drawer 50 as a moveable furniture part. The drawer 50 comprises a bottom 51, which is held on holders 52 on opposite sides in each case on a pullout guide 1. The holders 52 are mounted on a running rail 3, which is movably held on a guide rail 2. The pullout guide 1 is arranged in each case on a side frame 53 of the drawer 50. At each pullout guide 1, an ejection mechanism is mounted, as shown in detail in Figures 1 to 9, wherein the same reference numerals are used for the same components below.

FIGS. 17 to 20 show the ejection system of FIGS. 1 and 16, the upper view showing the pullout guide and the ejector mechanism on the left side, while the lower view shows the pullout guide and the ejector mechanism on the right side of the drawer 50. In Fig. 17, the drawer 50 is shown in a shooting position in which both ejection mechanisms are arranged in a latched closed position. The guided via pins 10 and 12 in the cam guide 7 activator 5 is located with a pin in the angled end portion 71 and thus is in spite of the bias of the spring 8 in a locked position.

In FIG. 18, in the ejection system, the cam 11 on the right (lower view) has been unlocked, with the corresponding pin being moved out of the angled end section 71. The unlocking can be done either by pulling or pressing on the drawer, since regardless of the direction of movement of the activator 5 provides for unlocking of the driver 11, as described above. On the left side (upper view), the driver 11 is still in a locked position, in which a pin 12 is held in the angled end portion 71 of the cam guide 7.

FIG. 19 shows the opposite case to FIG. 18, in which the left-hand side (upper view) is unlocked and the driver 11 is moved in the opening direction via the spring 8. The driver 11 is coupled via the activator 5 with the running rail 3. On the right side (lower view) of the drawer 50, however, the driver 11 is still in the locked position and the driver 11 is held with a pin on the angled end portion 71 of the cam guide 7.

If a discharge mechanism on the right or left side has been unlocked in the discharge system on the drawer, a forced release takes place on the opposite side. For this purpose, the fact is used that the unlocked driver 11 is moved by the force of the spring 8 in the opening direction and this force is transmitted via the activator 5 and the running rail 3 to the drawer 50. This will cause the ejection mechanism to lying side over the drawer 50, the running rail 3 and the activator 5 also applied with a force, this force is sufficient to pull the driver 11 from the locked position. For this purpose, the middle web 16 engages the activator 5 in the receptacle 14 and pulls the driver 11 in the straight portion of the cam guide 7. This will force a

Synchronization achieved, even if only one-sided unlocking was effected.

FIG. 20 shows the ejection system of FIG. 16 with drivers 1 1 unlocked on both sides. Both drivers 1 1 are moved in the straight portion of the cam guide 7 and are now moved due to the force of the spring 8 in the opening direction. The drivers 11 are coupled to the activators 5, which engage with two webs 16 and 17 in the receptacle 14. 21 shows a pullout guide 1 ", in which a running rail 3 is movably mounted on a guide rail 2, wherein the same components are also provided with the same reference numerals with the preceding embodiments, a rotatably mounted activator 5" is provided on the running rail 3, which engages in a receptacle on a driver 11 "The driver 1 1" is displaceably mounted on two cam guides 7 and 45 of a housing 6 "A pin 10 of the driver 1 1" is guided in the cam guide 45, but a pin 12 is During closing, the straight end section of the cam guide 45 forms a fulcrum for the driver 11 'via the pin 10. By the guided in the cam guide 7 "pin 12 of the driver 1 1" is pivoted upon reaching the curved end portion 71. When opening the straight end portion of the cam guide 7 "forms over the pin 12 a pivot point for the driver 11". By guided in the cam guide 45 pin 10 of the driver 11 "when reaching the curved

End portion 70 pivoted. The respective pivoting of the driver 1 1 "leads to the release of the activators 5" and 41. Furthermore, the pivotable mounting of the activators 5 "and 41 allows overrunning of the driver 11" in the end positions of the driver 11 "in the bent end portions 70 and 71 the cam guides 7 "and 45. Alternatively, the activators can also be performed, for example, vertically displaceable. In Figure 21, the closed position of the drawer is shown, on which the driver 1 1 "is fixed to an angled end portion 71 of the cam guide 7" and is biased by the force of a spring 8 in the opening direction. On the guide rail 2, a holder 46 for attachment of the energy accumulator 8 is provided. About a fixation 47 of the energy storage 8 is fixed to the holder 46. The other end of the force accumulator 8, designed as a tension spring, is fixed on to the driver 11 "with a spring eye via the bolt 48

Change in the spring force, the fixation 47 is designed to be displaceable and fixable on the holder 46.

In order to unlock the driver 11 ", it is possible to pull on the drawer so that the activator 5" coupled to the running rail 3 pulls out the carrier 11 "from the angled end portion 71, as shown in FIGS. 22A and 22B Then, the cam 11 "is moved in the opening direction by the force of the spring 8. With the running rail 3, a second activator 41 is further connected, which is in engagement with a second driver 42, which is guided in a second cam guide 43. The curve guide 43 and the

Driver 42 are connected to a self-closing mechanism 44, which holds the drawer in the closed position in the closed position. The Selbsteinzug 44 may further include a damper 49 to decelerate a closing movement to avoid impact noise. Furthermore, an overpressure, a direct triggering after the closing operation, is avoided by the damping.

In Figures 23A and 23B, the cam 11 "is shown in a position created by unlocking by pushing the drawer in. The activator 5" comprises a downwardly projecting web 40 on which a front stop surface 18 "is formed. This abutment surface 18 "is adjacent to a jack 25 rotatably mounted on the housing 6" about an axis 26. The lever 25 may be biased in a home position by a spring or moved by gravity to a home position Pressed furniture body, the web 40 moves in Figure 23B to the right and pivots the lever 25. Thereby passes an upper stop edge 27 of the lever 25 against an underside of the driver 11 "and pushes it upwards from the angled end portion 71 of the cam guide 7" out Thus, the driver 11 "is not fixed by the lower projection 16" in the receptacle 14 "of the driver 11", the activator is the fifth "also pivotally mounted and therefore can be easily pivoted by the lever 25 and the driver 11" clockwise to a stop. Then pulls the driver 11 "after unlocking by the force of the spring 8, the activator 5" in the opening direction. 24A and 24B, the position is shown when the second activator 41 travels over the parked driver 1 1 "The activator 41 has a rib-shaped design and is pivotably mounted on the running rail 3. As a result, the activator 41 can be attached to the runner 56 via a run-on slope 56 Driver 1 1 "pivoted upward and moved in the opening direction.

If the running rail 3 is moved in the closing direction, first the second activator 41 engages in the receptacle 14 "of the driver 1 1" and pulls the carrier 11 "out of the parked position in order to tension the spring 8. The driver 11" is over a first pin 10 in a cam guide 45 and a second pin 12 in a cam guide 7 ". The cam guides 7" and 45 each include an angled end portion 71 and 70, respectively, to engage the cam 1 "at the end of the cam guides 7". 45 to pivot. It is also possible to provide only a single curved guide with two angled end sections 70, 71.

During the closing movement of the driver is 1 1 "parked by the second activator 41 at the angled end portion 71 of the cam guide 7", wherein by the pivoting of the driver 11 "of the activator 41 disengaged from the driver 1 1" passes and the drawer further into Closing posture can be moved.

In order to bring the activator 5 "into engagement with the driver 11", the drawer is moved further in the shooting direction according to FIGS. 25A and 25B until the activator 5 "reaches the driver 11" on a run-on slope 55 and is thereby pivoted , The activator 5 "can then be displaced along the starting bevel 55 until it engages in the receptacle 14" on the driver 11 ". At the same time, the second driver 42 of the self-retraction pulls the second activator 41 into the firing position, so that the Closing movement shortly before the closing movement manually no longer needs to be supported.

The self-closing also serves to lock the movable furniture part or the drawer 50. The tumbler prevents unwanted opening such. by shaking or slight inclination of the furniture in which the ejection device are installed with a pullout guide and a movable furniture part.

Also in the embodiment shown in Figures 21 to 25, it is of course possible to provide two pullout guides that allow unlocking according to the inventive ejection system, even if by the unlocking process on one side only a driver 1 1 "from the unlocked position was unlocked. The force of the spring 8 of the unlocked carrier 11 "then ensures an unlocking of the other driver 11" on the second pullout guide. A further exemplary embodiment of a pull-out guide 1 "'according to the invention, which comprises a guide rail 2 and a running rail 3, wherein the same reference numerals are used for identical components, is connected to the running rail 3. An activator 5"' is connected to the running rail 3 The driver 11 '"is guided along a curve guide 7'" on a housing 6 "'and biased by a spring 8 in the opening direction. The spring 8 is fixed on the end facing away from the driver 11 '"by a bolt 180 on a holding web 181 and an adjustment bar 182, wherein on the holding web 181 openings and on the holding web 182 recesses are formed, in which the bolt 180 can be inserted. Thereby, the tension of the spring 8 can be adjusted.

On the driver 11 '", a first lever 91 is pivotally mounted on a receptacle and a second lever 92 is pivotally mounted on an opposite side of the driver 11'.

In Figure 27, the pullout guide 1 '"is shown in a slightly open position with the second activator 41 abutting the lifter 92 on the cam 11"' to move the cam 11 '' from the parked position along a ramp 70 '' Curve guide 7 '"pull out.

The driver 11 '"is then moved along the cam guide 7'" by the second activator 41 until the driver 11 '"reaches the angled end section 71 and is pivoted downwards, thereby releasing the activator 41 and allowing the track rail 3 to move moved without coupling with the driver 11 '"in the closing direction.

In Figure 29, the latching position is reached when the activator 5 '"reaches the driver 11'". The activator 5 'then passes over the pivotable lever 91 and thereby moves between the levers 91 and 92. The second activator 41 then comes into engagement with the driver 42, which is movable along the cam guide 43 and through the self-closing mechanism 44 in the closing direction is moved until the closed position is reached. The closed position of the pullout guide is shown in FIGS. 3OA and 3OB. The activator 5 '"is in engagement with the driver 11'" and can be unlocked both by a movement of the running rail 3 in the closing direction and in the opening direction.

In FIG. 3OB, the position of the activator 5 '"on the driver 11'" is shown enlarged. The activator 5 '"is locked behind the lever 91, the lever 91 being pushed up by a spring, whereby the activator 5" can now engage the lever 91 and the driver 11' "to move by a pulling movement Move the driver 11 '"again in the opening direction of the drawer.

Alternatively, as shown in Figures 31A and 31B, it is possible to unlatch the cam 11 "by pushing the drawer in. Then, a downwardly directed web 40 of the activator 5 '" engages and pushes a rotatably mounted lever 25 about an axis 26 so that the lever 25 pushes the driver 11 '"upwards and thereby unlocking is effected.On the opening process, the second activator 41 can now move over the lever 92, in which case the lever 92 is pivoted and again by the force of a spring Contact with the lever 91 is avoided by the bevel 70 "'of the cam guide 7'".

31B shows a projection 16 "as well as an abutment surface 18 '" via which the unlocking of the carrier 11' "takes place from the bent end section 71. After being released, the carrier 11 '" is moved by the energy accumulator

8 moves along the curved guide 7 '". The activator' engaged 'moves via the attached running rail 3 the movable furniture part coupled to it in the opening direction. FIG. 32 shows a further exemplary embodiment of an ejection mechanism according to the invention for a pull-out guide 1 "". Shown in Fig. 32 is an ejection mechanism comprising a modified housing 6 "" in which a first cam guide 7 "" is formed with a bevel 70 "'at one end and an angled end portion 71 at the opposite end A third cam guide 65 is formed in the horizontal direction, and a recess 66 for engaging a lever 25 is provided, into which an axle 26 engages a driver 11 "" unlocked, a first pin 10 and a second pin 12, both of which are guided in the cam guide 7 "". The driver 11 "" is biased in the opening direction via a force accumulator 8, designed as a tension spring. The housing 6 "" is formed in two parts, so that on both sides of the driver 11 "" a corresponding housing part with the cam guides 7 "", 64 and 65 is formed.

On a running rail or a drawer bottom a Haiter 89 is provided, which is in the closing direction against a stop 90 of an activator 5 "" anbar- bar. The activator 5 "" is guided between the two housing parts of the housing 6 "" and comprises a first vertical receptacle 83, in which a pawl 81 is resiliently mounted, a second vertical recess 84, in which a second pawl 80 is resiliently mounted, and a third vertical receptacle 85 for a locking pin 87. The pawls 80 and 81 are biased downwardly by springs to act on the cam 11 "". The locking pin 87 is movably mounted in the vertical direction in the activator 5 "".

FIGS. 33A and 33B show the ejection mechanism on a pull-out guide with a guide rail 2 and a movable running rail 3. The ejection mechanism is in a closed position in which the driver 11 "" is locked to the angled end portion 71 of the cam guide T ". The activator 5" "comes into abutment against an elastic stop 31" "in a holder 32". The elastic stop prevents overpressure, a direct re-triggering of the ejection device at or shortly after the closing operation As shown in Figure 33B, the drawer can be opened by pulling, then the holder 89 on the

Locking pin 87 acts, which in turn moves the activator 5 "" in the opening direction, so that the pawl 80 pulls over its projection 16 "" the driver 11 "" from the locked position. Further, an opening can be achieved by moving the drawer in the closing direction, in which case the abutment surface 18 "" of the opposite pawl 81 acts on the lever 25, which pivots about the axis 26 and thereby the driver 11 "" from the angled end portion 71 lifts. The driver 11 "" then slides with the two pins 10 and 12 in the cam guide 7 "" due to the force of the energy accumulator 8 up to the inclined portion 70 "".

In Figs. 34A and 34B, the cam 11 "" has arrived at the inclined portion 70 "". The driver 11 "" is pivoted downwards by the guidance of the journal 10 on the bevel 70 ", so that the pawl 80 disengages from the driver 11"". The pawl 80 can now travel over the driver 11"". are moved and the second pawl 81 has a Aniaufschräge 82 and can be pressed by the contact with the driver 11 "" up against the force of a spring and moved in the opening direction. As a result of the movement in the opening direction, the locking pin 87 is pushed downwards, with the locking pin 87 being guided by a guide pin 88 in a corresponding recess of the activator 5 "".

In FIGS. 35A and 35B, the running rail 3 has been moved further in the opening direction, with the projection 90 still resting on the block 89. The locking pin 87 has been moved downwards along the obliquely downwardly extending guide 64 and has now released the block 89. As a result, the running rail 3 can be moved further in the opening direction and is now decoupled from the activator 5 "". FIG. 35A shows receptacles 93 for fixing the force accumulator 8, designed as a tension spring, on the housing 6 "". In the opposite in two housing parts of the housing 6 "" arranged receptacles 93, a bolt 94 is inserted for fixing the force accumulator 8 at one end. The bolt 94 is designed so that it can be inserted to change the force of the force accumulator 8 designed as a tension spring at different positions in the receptacles 93 of the housing 6 "". At the driver 11 "", the other end of the force accumulator 8 is fixed by a bolt 95.

For a closing operation, the running rail is then moved in the closing direction until the block 89 abuts against the projection 90, so that the activator 5 "" is moved a little in the closing direction until the position shown in FIGS. 36A and 36B is reached. In this position, the block 89 between the projection 90 and the locking pin 87 is locked again and the pawl 81 abuts a projection of the driver 11 "" at. As a result, the driver 1 1 "" is now moved in the closing direction along the curved guide 7 "" until the

Driver 1 1 "" with the pin 12 pivoted at the angled end portion 71 down and thereby locked. Then, the position shown in Figs. 33A and 33B is reached. In Figure 37, another embodiment of an ejection mechanism in the assembled position is shown.

A push element 101 is designed as a drawer and can be mounted movably in a furniture body. For this purpose, a guide rail 102 a Extent guide provided on the at least one track rail is movably mounted. The running rail is located in a hollow side frame 103 of the drawer and a bottom 105 of the drawer is fixed via a plurality of holders 106 on the running rail. The direction of movement X of the sliding element 101 is indicated by arrows in the drawings.

At the bottom of the bottom 105, a housing 107 is mounted, which consists essentially of two plate-shaped housing parts, are recessed on the slot-shaped cam guides 108, 109 and 110. In the housing 107 projects a web-shaped activator 116 which is fixed to the furniture body or the stationary guide rail 102. Activator 116 is only partially illustrated for clarity.

The push element 101 is held in a closed position via a retraction device 104, such retraction devices 104 being known as self-closing devices and being able to be mounted in a compact design adjacent to the drawer guide.

In Figure 38, the ejection device according to the invention is shown in a closed position. The collection device 104 comprises a collection housing 140 with a

Curve guide 141 with an angled end portion 142. In the intake cam guide 141 a Einzugsmitnehmer 143 is movably mounted, which is coupled to a web-shaped Einzugsaktivator 144. With the feeder housing 140, a damper 145 is coupled, also located in the feeder housing 140, a spring for biasing the Einzugsmitnehmers 143 in the closing direction.

As a result, the pull-in activator 144 arranged on the movable push element 101 or the running rail is pretensioned in the closing direction. The retraction device 104 may further comprise a damper to decelerate a closing movement before reaching the Schiießbewegung.

In Figure 38, the web-shaped activator 116 is further recognizable, which is fixed end in a receptacle of a driver carriage 113. The driving carriage 113 comprises on the side facing away from the activator 116 side, a first movable pawl 114 and a second movable pawl 115, which are resiliently mounted and can be pressed into the driving carriage 113. In the shooting position, the second pawl 115 is in engagement with a driver 111, which is movably mounted via pins in the first cam guide 118. The driver 111 is biased via an energy storage in the form of a tension spring 112 in the opening direction. The remote from the driver 111 end of the spring 112 can be fixed to the housing 107. The driver 111 can be latched against an angle at an angled end portion 171 of the cam guide 108 against the force of the spring 112. At the opposite end of the curved guide 108, an angled end section 170 is likewise formed, on which the catch 111 can be swiveled.

Since the driver 111 is in the latched position, acting on the housing 107 via the Mitnehmerschlitten 113 no forces in the opening direction. The retractor 104 holds the pusher 101 in the closed position.

In Figure 39, the ejection device is shown when unlocking the driver 111. For this purpose, the thrust element 101 is pressed into the furniture body, so that the first pawl 114 presses against a pivotable Auswerferhebei 130. The ejector lever 130 is movably mounted on the housing 107 about an axis 131. A leg 132 of the ejector lever 130 is located on the pawl

114, while the opposite leg 133 abuts against the driver 111. By pushing the pusher 101, the ejector lever 130 is rotated counterclockwise about the axis 131 so that the leg 133 moves the pawl 111 out of the angled end portion 171 of the cam guide 108. As a result, the driver 111 is unlocked and now pulled by the force of the spring 112 along the cam guide 108. The driver 111 abuts with a tip 150 against a stop 151 of the driver carriage 113, so that the driver carriage 113 is moved together with the driver 111. As a result, an integrally formed wall 117 presses against the stationary activator 116, so that the housing 107 together with the push element 101 is moved in the opening direction.

In Fig. 40, the ejection device is shown in a slightly open position. The driver 111 is located in a central region of the first Kurvenfüh- tion 108 and is further acted upon by the spring 112 with a force. As a result, the driving carriage 113 is also moved to the right, wherein the driving carriage 113 can be moved along a second curved guide 110. The cam guide 110 is formed linearly and the driving carriage 113 therefore moves linearly along the housing 107 via guide means. A movable stop 118, which can be moved via a pin 119 in a third cam guide 109, is also provided on the driving carriage 113. The third cam guide 109 is disposed inclined to the second cam guide 110, so that the stop 118 is moved when moving the Mitnehmerschiittens 113 to the right in Figure 40 down. The stop 118 is perpendicular to Movement direction of the carrier carriage 113 held in a Langioch 120 movable.

In the position shown in FIG. 40, the pull-in device 104 is decoupled from the pull-in activator 144, since the catch 143 has been moved along the pull-in curve guide 141 to the angled end section 142 and is parked there in a pivoted manner. As a result, the pull-in activator 144 is released and can now continue to move independently of the pull-in cam 143 in the opening direction.

In Figure 41, the ejection device is shown in a position in which the driver 111 has reached the angled end portion 170 and thereby pivoted. In the pivoted position, the pawl 115 and the carrier slide 1 13 can move independently of the driver 11 1 to the right, so that the housing 107 together with the pusher 101 in

Opening direction is moved. The thrust element 101 is no longer accelerated by the force of the spring 11.

The movable stop 1 18 continues along the cam guide 109 and continues to descend, wherein the activator 16 is still held in the receptacle between the movable stop 118 and the wall 17.

In FIG. 42, the ejection device is shown in a position in which the movable stop 118 has been moved downwards so far that the web-shaped activator 116 has been released. As a result, the housing 107 can now be moved along with the Mitnehmerschlitten 113 in the opening direction, that is independent of the stationarily arranged activator 1 16. In the further opening movement, the first pawl 114 slides over the driver 111 and is briefly up against the force of a spring pressed and locked behind the driver 1 1 1 again, with the pawl 114 for this purpose a corresponding

Run-on slope 124 is formed.

In Figure 43, a position is shown when the pusher 101 is moved back in the closing direction. First, the pawl 114 engages the driver 1 1 1 and pulls it out of the parked position at the angled end portion 170, wherein the driver 11 1 is moved against the force of the spring 1 12 along the cam guide 108. In this case, the driving carriage 1 13 with the wall 1 17 is supported on the activator 116, so that the driving carriage 1 13 along the cam guide 1 10 is moved. FIG. 44 shows a position of the ejection device before reaching the closed position. The carrier slide 1 13 is moved so far along the cam guide 110, that the movable stop 1 18 back to the actuator 1 16 is arranged and this now between the stop 118 and the

Wall 117 is held. The first pawl 114 has moved the driver 1 1 1 as far along the cam guide 108, that the spring 1 12 utes largely stretched. In the position shown, the pull-in activator 144 now engages the pull-in catcher 143, so that it is unlocked and the pull-in device 104 is activated.

In Figure 45, the ejector is shown before reaching the closed position when the driver 11 1 has reached the angled end portion 171 and is now locked against the force of the spring 112. As a result, the driver pivots 1 1 1 and the first pawl 1 14 can now be moved over the driver 1 1 1. The Mitnehmerschiitten 1 13 is now further along the second cam guide 1 10 moves, now the retraction device 104, the thrust element 101 pulls in the closing direction, so that this after tensioning the spring 1 12 and locking the driver 1 1 1 without further use of force by the user can be moved. The pusher 101 thus enters automatically.

In Figure 46, the ejector is shown shortly before reaching the closed position. The second pawl 1 15 now slides with a run-on slope over the driver 1 1 1. The driver carriage 1 13 is still moved by the retraction device 104 in the closing direction.

In Figure 47, the closed position is shown, in which the second pawl 1 15 is latched behind the tip 151 of the driver 11 1. The pawl 115 is also resiliently mounted on the driving carriage 113. The movable stop 118 is extended by the movement along the cam guide 109 and in the slot 120 again and the activator 1 16 is therefore between the movable stop 1 18 and the wall 1 17 enclosed. A spring buffer 122 prevents the ejection device unintentionally re-initiating an opening operation after the closing operation. Furthermore, the diaphragm gap is generated via the spring buffer 122, in order to enable triggering of the ejection device by pressure in the closing direction.

When unlocking the thrust element 101 was pressed into the furniture body, so that an unlocking of the driver 11 1 on the ejector 130 is done. However, it is also possible to unlock the driver 111 by pulling on the thrust element, since then the driver 111 is pulled out of the angled end portion 171 and then the position shown in Figure 28 can be shown without moving the Auswerferhebeis 130. The driver 111 is again in a central portion of the cam guide 108 and is unlocked, otherwise the ejection process and the subsequent closing is done as described above.

The ejection devices according to the invention can be used with all linearly displaceable furniture parts, for example with sliding doors.
