专利说明:

The invention relates to an ejection device with the features of the preamble of claim 1.
Furthermore, a piece of furniture with the features of the preamble of claim 19 is to be specified.
Ejection devices of this type, also known as unfolding aids, are already known and are shown, for example, in Austrian patent application A 50049/2017. These ejectors are needed as a folding aid to folding doors, which as well
Folding sliding doors can be designed to move from their closed position into an open position. The user of the folding door or folding sliding door does not have to carry out the entire movement of the folding door or folding sliding door automatically from the closed position into the open position. For example, by pushing the folding door or folding sliding door in the closed position in the direction of the furniture body located behind it, the ejection device is activated and the folding door or folding sliding door is pushed out of the closed position in the direction of the open position. The ejection device is thus regarded as a folding aid which is arranged between the door leaves. Since the ejection device is arranged in the invisible area behind the door leaves and the door leaves have to move from the closed position into the open position, only a small space is made available in which the ejection device can be found. Since the door leaves, which are movable relative to one another, can be moved from a coplanar position (closed position) to a substantially parallel position (open position), and in this parallel position only a little space is made available between the door leaves, which are arranged to be movable, in the prior art Pockets are incorporated into the door leaf to accommodate the moving components of the ejection device as soon as the ejection device has to compensate for the movement of the door leaf between the open position and the closed position. The swivel levers necessary for the unfolding aid, which move the door leaves towards each other, find enough space between the door leaves in the closed position. However, as soon as the door leaves move in the direction of the parallel position or are essentially in the parallel position, these pivot levers must find themselves in the limited space between the door leaves without collision. A parallel position would not be possible in the event of a collision. Thus, a compact arrangement of the door leaves guided into the open position would not be guaranteed, in order to be able to sink them into a feed shaft, for example. The necessary recesses in the door leaves for lowering the swivel levers must be made at the required location using a manufacturing process, such as milling or cutting
2/27. This includes an additional work step and is reflected in an increased workload and higher production costs. In addition, the thickness of the door leaf at the point of the milling is weakened, which could lead to damage to the folding door at this point over a longer period of time. Furthermore, the material thickness of the door leaves must be raised enough to be able to realize the bags at all; a thin-walled folding door cannot be used.
The object of the invention is to avoid the disadvantages described above and to provide an ejection device which is improved compared to the prior art.
Furthermore, a piece of furniture improved with respect to the prior art is given with such an ejection device.
This is achieved in the ejection device according to the invention by features of the characterizing part of claim 1 and in the improved furniture with the features of claim 19.
If the at least one ejection element for moving the second door leaf from the closed position into the open position is formed by at least one scissor mechanism, the scissor mechanism being foldably mounted between the first and the second door leaf, no recesses such as pockets or recesses in the door leaves are required, in order to provide the space required for the pivoting-in levers or other movable components of the ejection device which is required when moving into the closed position. The scissor mechanism can compensate for the movements independently and folds in between the door leaves. In this way, an ejection device is created which, in the parallel position (open position) of the door leaves, finds space compactly between the door leaves which are movable relative to one another. The construction of the individual levers is independent of the dimensions of the door leaves. Thus, for example, thinner materials can also be used on the door leaves, since the depressions in the door leaves are no longer necessary.
If the scissor mechanism is made up of at least a first scissor lever and a second scissor lever, the first and the second scissor lever preferably being connected in a central area - via an articulated connection, two scissor levers are available that measure the forces when opening and closing the Can accommodate folding door. In addition, it is achieved that, for example, a scissor lever can be driven, which can automatically bring about the movement of the second scissor lever. A compact drive system is generated to unfold the
3.27
To be able to support the folding door. The resulting forces are also better distributed over several scissor levers, which leads to a more stable design of the system.
If the articulated connection is formed by at least one intermediate lever, a virtual pivot point is established on the scissor mechanism. The intermediate lever achieves an even more compact design with better power transmission than with a simple joint. Because the pivot point is virtual, it can move when opening and closing the folding door. It is provided that the intermediate lever is articulated to the first scissor lever and / or the second scissor lever. The articulated connection of the intermediate lever with the first and / or the second scissor lever transfers the force when opening and closing the door leaves via the articulated connection. Furthermore, the door leaves are positioned to each other and stably supported.
If the first scissor lever is movably mounted at a first end along a guide device on the first fitting and a second end of the first lever is articulated to a second fitting part, the first scissor lever can move along the guide device when opening and closing the folding door, which is in reflects a compact design. A part of the degrees of freedom required by the scissor mechanism is created by the guide device in order to be able to realize the folding when moving between the open and closed positions.
If the second scissor lever can be brought into contact by means of a contact section with a control curve arranged on the first fitting, the contact section can move along the control curve as soon as the scissor mechanism is in the corresponding position. The contact between the contact section and the control cam enables the second scissor lever to be pivoted, the first scissor lever being able to be carried along due to the articulated connection between the scissor levers due to the pivoting of the second scissor lever. The control curve does not only move the
Scissor mechanism, but also offers the degrees of freedom that the scissor mechanism requires for folding and unfolding. Using the control cam, it is possible to position the door leaves in the desired position relative to one another. The control curve thus defines the path of the scissor mechanism and also the path of the door leaves to each other.
It has been found to be an advantage that an energy store arranged on the scissor mechanism supports the movement of the scissor mechanism as soon as the folding door is brought from the closed position into the open position. The force for moving the door leaves from the closed position therefore no longer has to be applied by the user. This
4/27 initiates the movement, for example by tapping the door or pushing it against a certain position; however, the opening of the door leaves takes place automatically to a certain extent.
It can be provided that the folding door moves completely from the closed position into the open position, or only up to a certain range, so that it can subsequently be opened completely by the user. It may therefore be the case that the folding door is moved by the ejection device only halfway between the closed position and the open position, and the rest of the way into the open position is carried out manually by the user. The force accumulator can be loaded by manual actuation in order to be able to discharge it, for example, when opening again.
If the energy accumulator is arranged on the fitting between the first and the second scissor lever and / or between the first and / or second scissor lever and the intermediate lever, a direct introduction of force takes place in the scissor mechanism. In addition, the energy accumulator is compact, which is reflected in the space-saving design of the ejection device. In addition, the force is applied directly and not indirectly via other levers or otherwise. Additional components are avoided that can wear out or be damaged, for example. It can be provided that the energy accumulator is formed by a spring, preferably a compression spring.
If the contact section of the second
The scissor lever can be pressed against the control curve, the contact section being movable along the control curve, the second scissor lever is moved against the control curve due to the force application of the force accumulator. This movement and the contact with the first scissor lever force the scissor mechanism to convert this force introduction of the energy accumulator into a movement against the control cam and against the first scissor lever. Conversely, a movement of the scissor mechanism against the control curve loads the energy accumulator in a certain operating position of the ejection device. The unloading and loading of the energy accumulator thus takes place via the control cam and the contact of the contact section on the second scissor lever.
If the energy store is mounted on an end section of the second scissor lever and presses the contact section, which is movably mounted on the second scissor lever - preferably displaceable - in a direction opposite to the end section, the length of the second scissor lever is variable, which is the case when the length of the second is changed
5.27
Scissor lever results in a direct implementation of the movement of the scissor mechanism and in an unloading and loading of the energy accumulator. If the length of the second scissor arm and / or the length of the energy accumulator attached to the second scissor arm changes due to the relief of the energy accumulator, the scissor mechanism is put into operation and a supportive movement of the door leaves from the closed position is generated.
If the control curve has an opening section and a clamping section, the contact section - preferably formed by a second scissor lever rotatably mounted rolling elements - along the opening section and the clamping section, the ejection movement of the scissor mechanism via the contact section, which moves along the opening section of the control curve manufactured, the folding door being opened. If the folding door is moved manually by the user, for example, the control cam moves into the tensioning section and charges the energy accumulator via the contact section for a further opening process.
It has turned out to be advantageous that a locking device is provided for locking the energy accumulator, the energy accumulator being able to be tensioned by the interaction of the control cam and the contact section, and the energy accumulator being locked in the tensioned state by the locking device, thereby preventing the energy accumulator from being discharged , Thus, in connection with the relative position between the contact section and the control curve, the energy store can be unloaded and loaded. When loaded, the energy store can be locked, which prevents the energy store from being automatically discharged. The lift mechanism can be triggered and discharged if the user so desires. Accidental discharge of the lift mechanism is excluded.
If a trigger device is provided, which in a trigger position
Unlocked locking device so that the energy storage device can be changed from the loaded to the unloaded state, the opening of the folding door is forced via this release device. This triggering device can be, for example, a connecting element which connects the ejecting device, at least temporarily, to another component of the piece of furniture or the furniture body as soon as the user presses against the folding door, for example. However, the triggering device can also be a push button or something comparable, which can be operated directly by the user. It is thus possible to attach the release device to the furniture in a concealed manner. However, the triggering device can obviously also be arranged on the furniture.
6.27
If the release device can be moved from an essentially coplanar position of the door leaves into the release position when the release device is pressed, then this can be arranged in a concealed position on the furniture. By pressing against the door leaves and overpressing their coplanar position, this release device is activated and the folding door is forced to open. This is also achieved in that the release device can be moved into the release position when the release device is pressed against the furniture body.
The hidden position of the release device is also achieved in that the at least one locking device when the ejection device is mounted can be unlocked by exerting pressure on the folding door, preferably in the area in which the door leaves are connected to one another in an articulated manner.
Furniture with a furniture body, at least one folding door, which comprises at least two hinged door leaves, is advantageous, the folding door or folding sliding door having at least one closed position, in which the at least two door leaves are arranged in a common closing plane, and an open position, in which the at least two door wings enclose an angle not equal to 180 ° to one another and can take up at least one ejection device.
It is advantageous if the at least one ejection device is arranged on a side of the two door leaves facing the furniture body. This results in a concealed construction of the ejection device. This is not visible from the outside of the furniture.
Furthermore, it has proven to be advantageous that the furniture body has a feed shaft formed by a cavity for receiving the at least one folding door in a folded-in pull-in position. This means that the folding door that is brought into the open position can be sunk on the side of the furniture body and does not protrude into the room. A space-saving piece of furniture is thus created, the folding door of which is always stowed away and is not in the way.
Further details and advantages of the present invention are explained in more detail below with reference to the description of the figures and with reference to the exemplary embodiments illustrated in the drawings.

FIG. 1a shows the furniture 100 with an intake shaft 33 arranged on the side of the furniture 100, in which the folding door 3 can be stowed in the folded state of the door leaves 3a, 3b. Figure 1a shows the closed position of the folding door 3. The folding door 3 can also be designed as a folding sliding door, as shown in Figure 1a. For this purpose, this is attached to the upper edge and / or the lower edge of the folding door 3 by a longitudinal guide that is not visible in FIG. 1a. In addition to the ejection device 1 at the door gap between the door flights 3a, 3b, hinges 50 are also arranged at the gap in order to enable the door wings 3a, 3b to pivot between an open position and a closed position. The feed slot 33 is formed by the furniture body 40 or is arranged on the furniture body 40. An invisible part of the furniture body 40 runs parallel to
Ejection device 1, in order to be able to make contact with the ejection device 1 if necessary. This component of the furniture body 40 can be, for example, a shelf, a cover plate or another component of the furniture body 40.
FIG. 1b shows the ejection device 1 from FIG. 1a in detail. The trigger device 17, which is movably arranged on the ejection device 1, comes into contact with a component of the furniture body 40 if necessary. To simplify matters, the furniture body 40 was not drawn in FIG. 1b. The triggering device 17 is designed as a contact part which, when the door leaves 3a, 3b are pressed over from the coplanar position shown in FIG. 1b, comes into contact with a component of the furniture body 40 with the furniture body 40 and then triggers. The ejection device is thus started and the movement of the door leaves 3a, 3b relative to one another begins. The ejection device 1 has a first
27.8
Fitting part 1a and a second fitting part 1b. The scissor mechanism 10 connects the first and the second fitting parts 1a, 1b. When triggered by the trigger device 17, the scissor mechanism 10 is set in motion by at least one energy accumulator 14, which results in the door leaves 3a, 3b being opened.
Figure 2 shows an exploded view of the ejection device 1 consisting of a first fitting part 1a and a second fitting part 1b. The majority of the individual components are located on the first fitting part 1a. This comprises a base element 52 which is connected to the first door leaf 3a via fastening sections. This can be connected to the first door leaf 3a, for example, by means of screws or similar fastening means. To simplify this, this is not shown in FIG. 2.
On the base element 52 there is at least one guide device 12 for receiving the guide elements 12b located on the first scissor lever 10a, which are arranged on a first end E1 of the first scissor lever 10a. The second end E2 of this first scissor lever 10a is connected to the second fitting part 1b. The guide elements 12b are rotatably connected to the first scissor lever via a pin 12a and can be moved longitudinally along the guide device 12 on the base element 52.
The first scissor lever 10a is connected to the second scissor lever 10b via at least one intermediate lever 11. The second scissor lever has a contact section 15 which can be brought into contact with the control cam 13 on the base element 52. Thus, the contact section 15 - designed as a rolling element - is supported at least temporarily on the control cam 13. At the opposite end of the second scissor lever 10b is the bearing 53a, which is supported by a bolt 53b on at least one energy accumulator 14 on the second scissor lever 10b. The energy accumulators 14 act against a slide 55 via a displacement device 54. The slide 55 also serves to receive the contact section
15. If the contact section 15 is moved by the control cam 13, these movements are transmitted by the carriage 55 to the energy store 14 and vice versa. The locking device 16 is provided for locking the carriage 55. This is rotatably mounted on the second scissor lever 10b via the bolt 53b. The locking device 16 is triggered or released via the trigger device 17, which is also movably mounted on the second scissor lever 10b. A corresponding depression 55b on the locking device 16 is connected via a projection 55a.
9.27
A push-through protection 60, which is operatively connected to a control device 61, prevents the ejection device 1 from being triggered prematurely. If, for example, the opening process from the closed position into the open position is interrupted by the user and the folding door 3 is pushed back into the coplanar position, the folding door 3 could be pushed out again. This is prevented by the push-through protection 60 and the control device 61. The push-through protection is in connection with the slide 55 and only releases it when the door should be opened properly.
FIG. 3a shows the closed position of the folding door 3, the door leaves 3a, 3b being in a coplanar position with respect to one another. The energy store 14 located behind the locking device 16 is excited. The trigger device 17 is spaced apart from the furniture body 40. Thus, the locking device 16 is in the locked state. The energy store 14 cannot land. Thus, the contact section 15 of the second scissor lever 10b is also located at the start of the control curve 13. The position of the contact section 15 relative to the control curve 13 remains due to the locked energy accumulator 14 at the beginning of the opening section OA. The opening section OA extends over at least half the path of the control cam 13 and merges into the clamping section SA.
Figure 3b shows the bottom view of the release device 17, which is in engagement with the corresponding feeder 55a via the projection 55b. The feed 55a is located on the locking device 16. The locking device 16 holds the energy store 14 in the tensioned position.
FIG. 4 shows the triggering of the triggering device 17. The force FB applied by the user acts against the door leaves 3a, 3b not shown in FIG. Due to the hyperextension from the coplanar position, the triggering device 17 is pressed against a component of the furniture body 40. The force of the user FB creates a counterforce FG on the
Trigger device 17 generated. The extension 55b of the release device is thus pulled out of the feed 55a of the locking device 16. The locking device 16 is now in the unlocked state. As shown in FIG. 4, this can be done by a component of the furniture body 40.
But also by, for example, a direct or indirect connection between the release device 17 and, for example, the second door leaf 3b or the second fitting part 1b. This connection can be, for example, a tensioned Bowden cable or a similar device which, when the door leaves are pushed over from the coplanar position
10/27 generates a triggering of the trigger device 17. Thus, direct contact to the furniture body 40 does not always have to be established in order to ensure that the ejection device 1 is triggered. There is also the possibility of triggering by connecting the triggering device 17 to a region of the exhausting device 1 that is movable relative thereto.
FIG. 5 shows the unlocked locking device 16. The energy store 14 now acts against the contact section 15, which moves along the opening section OA of the control cam 13 and also sets the scissor mechanism 10 in motion by the connection to the intermediate lever 11. The second scissor lever 10b moves the first scissor lever 10a via the intermediate lever 11, which is attached to the second scissor lever 10b at the articulation point G1. The first scissor lever 10a is connected to the via a guide element 12b
Guide device 12 connected to the first fitting part 1a. The ejection device 1 is thus moved from the coplanar position towards the open position via the energy accumulator 14, the articulation point G1, the intermediate lever 11 and the first scissor lever 10a.
The movement takes place about the axis of rotation 51.
FIG. 6 shows a further position between the closed position and the open position of the ejection device 1. The energy store 14 continues to discharge, the second scissor lever 10b moves the first scissor lever 10a over the first articulation point G1 and the second articulation point G2 and the intermediate lever 11 arranged between them
Guide device 12. The contact section 15 moves along the control curve
13. The scissor mechanism 10 is thus supported on the base body 6.
FIG. 7 shows an opening angle of approximately 90 ° of the ejection device 1. For simplification, the first and second door leaves 3a, 3b were not shown, the angle of which would now also correspond to approximately 90 ° to one another. The energy accumulator 14 continues to discharge until the contact section 15 has arrived at the end of the opening section OA of the control cam 13. If the contact section 15 is located at the end of the opening section OA and thus at the transition of the clamping section SA, the energy accumulator 14 is completely relieved.
The scissor mechanism 10 then no longer moves automatically due to the force influence of the energy accumulator 14. Moving further from this position into the fully open position of the ejection device 1 can take place, for example, via a furniture drive or now also manually by the user.
FIG. 8 shows how the scissor mechanism 10 behaves when the second fitting part 1b is pivoted further in order to load the energy store 14. The energy store 14 is loaded
11/27 via the contact section 15, which is now in the clamping section SA. The angle between the first fitting part 1a and the second fitting part 1b is further reduced by a furniture drive or manual actuation by the user. The contact section 15 is forcibly moved on the control cam 13 along the tensioning section SA, which leads to tensioning of the energy accumulator 14. In parallel, the scissors mechanism 10 can move further in order to bring the door leaves 3a, 3b, which are not shown in FIG. 8, into their open position (parallel position). The tensioning of the energy accumulator 14 takes place via the slide 55 which is connected to the contact section 15. Because of the contact of the contact section with the control cam 13, this now moves against the actuating force of the energy storage device 14. In addition, it can be seen how the locking device 16 with its locking section 16a approaches the corresponding locking section 16b. In this case, the locking portion is 16a and the corresponding one
Locking section 16b formed by a positive connection, for example by a notch with a bolt.
FIG. 9 shows how the folding door 3 (not shown in FIG. 9) is brought further in the direction of the open position. The contact section 15 is located just before the most pronounced area of the control cam 13 in the clamping section. The energy accumulator 14 is thus just before its most tense position. The locking device 16 is just before the locking point. The scissors mechanism 10 is folded further and takes its place between the door leaves 3a, 3b, which are not shown in the figure. A small spring 59 in the swiveling range of the locking device 16 primarily presses it into the locking position in order to ensure secure locking as soon as the locking sections 16a, 16b form-fit one above the other or one inside the other.
FIG. 10 shows the ejection device 1 shortly before the open position, which essentially corresponds to the parallel position of the folding door 3 which cannot be seen in FIG. 10. The contact section 15 has arrived shortly before the end of the clamping section SA of the control cam 13. The energy accumulator 14 is almost completely tensioned. Because the
Locking device 16 has moved away from the release device 17 along the longitudinal axis of the energy accumulator 14, no release can take place in the parallel position of the door leaves 3a, 3b. Thus, in the parallel position of the door leaves 3a, 3b, no contacting of the trigger device 17 with the locking device 16 is provided, since no unlocking of the energy store 14 is desired in the open position.
FIG. 11 shows the parallel position of the folding door 3. The parallel position corresponds to the open position of the folding door 3, in which the first door leaf 3a is essentially relative to the second door leaf 3b
12/27 is in a parallel position. The ejection device 1 is now in the folded state between the door leaves 3a, 3b. The spring 14 is completely tensioned. The locking device 16 is closed due to the corresponding locking sections 16a, 16b.
Due to the distance of the trigger device 17 from the locking device 16, triggering in the open position of the folding door 3 is not possible. The contact section 15 is in the end position on the control cam 13. In this open position, the folding door can be pushed into the insertion slot 33 shown in FIG. This insertion into the slot 33 can be done by a drive or by the force of the user. The drive out of the slot 33 can also be done via a drive. The folding door 3 brought into the open position is thus ejected from the insertion slot 33 and can then be brought into the closed position again by the user via an additional drive or also manually.
The ejection device 1 is virtually idle during the movement from the open position into the closed position and moves from the open position into the closed position in the tensioned state in order to be able to ensure a renewed triggering. In the completely folded state of the ejection device 1, the guide element 12b is located at the end of the guide device 12.
Figure 12 shows the ejection device 1 when pivoting back from the open position into the closed position. The guide element 12b of the first scissor lever 10a is moved along the guide device 12. The scissor mechanism 10 remains in the folded state since it is locked by the locking device 16. The locking device 16 remains closed via the locking sections 16a, 16b. The energy store 14 remains charged. The contact section 15 moves away from the control cam 13. There is no contact between the contact section 15 and the control cam 13.
FIG. 13 shows the ejection device 1 just before the coplanar position (closed position) of the door leaves 3a, 3b. The scissor mechanism 10 still remains in the folded state. It can be seen that the trigger device 17 closer to the
Locking device 16 moves in order to ensure that it can be triggered again in the coplanar positions. The contact section 15 is moved away from the control cam 13 and does not engage with it.
13/27
FIG. 14 shows the ejection device 1 in the coplanar position of the folding door 3. It is striking that the release device 17 is not yet in engagement with the locking device 16. A new triggering is not yet possible. This is due to the
Push-through protection, which is to prevent the door from being opened again immediately by the closing movement and when the coplanar position is exceeded. A delay in the engagement of the trigger device 17 in the locking device 16 should thus take place. This is done via the control device 61, which causes the triggering device 17 to be readjusted with a time delay. The control device 61 can be designed, for example, in the form of a damper, rotary damper or the like. To readjust the trigger device 17, this takes longer than the closing process of the door leaf 3.
FIG. 15 shows how the push-through protection has been removed via the control device 61. The release device 17 was correspondingly engaged with the locking device 16 in order to ensure that the release device can be triggered again. A renewed triggering begins as soon as the push-through takes place via the coplanar position of the door leaves 3a, 3b, as shown in FIG. 4.
