Definitions

  • the invention relates to an ejection device having the features of the preamble of claim 1.
  • Such ejection devices or also called unfolding aids, are already known and are for example in Austrian patent application A 50049/2017 , the JP 2014 029 103 A , the JP 2012 001 916 A and the WO 2017 000006 A1 shown.
  • These ejection devices are required as unfolding aids in order to move folding doors, which can also be designed as folding sliding doors, 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 from the closed position into the open position himself.
  • the ejection device is activated and the folding door or folding sliding door is ejected from the closed position in the direction of the open position.
  • the ejection device is thus regarded as an unfolding aid which is arranged between the door leaves. Since the ejection device is arranged in the non-visible area behind the door leaves, and the door leaves have to move from the closed position to the open position, only a small space is made available in which the ejection device is located can arrive.
  • the prior art Since the door leaves, which are movable relative to one another, can be moved from a coplanar position (closed position) into a substantially parallel position (open position), and in this parallel position only little space is left between the door leaves arranged so as to be movable relative to one another, the prior art has to Pockets are incorporated into the door panels to accommodate the moving components of the ejector can when the ejector must compensate for the movement of the door panels between the open position and the closed position.
  • the material thickness of the door leaf is weakened at the point of the cut-out, which could lead to damage at this point on the folding door over a longer period of time. Furthermore, the material thickness of the door leaf be sublime enough to be able to realize the bags at all; a thin-walled folding door can therefore not be used.
  • the object of the invention is to avoid the disadvantages described above and to specify an ejection device which is improved over the prior art.
  • the at least one ejector element for moving the second door leaf from the closed position into the open position is designed by at least one scissor mechanism, with the scissor mechanism being mounted in a collapsible manner 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 moving into the closed position for the pivoting lever or other moving components of the ejection device.
  • the scissor mechanism can independently compensate for the movements and folds itself between the door leaves. In this way, an ejection device is created which, in the parallel position (open position) of the door leaves, can be compactly accommodated between the door leaves which can be moved relative to one another.
  • the construction of each Lever is independent of the dimensions of the door leaf. This means that thinner materials can also be used on the door leaves, for example, since the depressions in the door leaves are no longer necessary.
  • the scissor mechanism is formed from at least a first scissor lever and a second scissor lever, with the first and second scissor lever being connected to one another - preferably in a central area - via an articulated connection, two scissor levers are available, which absorb the forces during opening and closing Closing the folding door can accommodate.
  • a scissor lever can be driven, which can automatically bring about the movement of the second scissor lever.
  • a compact drive system is generated in order to be able to support unfolding of the folding door. The resulting forces are also better distributed over several scissor levers, which leads to a more stable design of the system.
  • the articulated connection is formed by at least one intermediate lever, a virtual pivot point is created 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 connected in an articulated manner to the first scissor-type lever and/or the second scissor-type lever.
  • the articulated connection of the intermediate lever with the first and / or the second scissor lever is the force when opening and closing the Door leaf transferred via the articulated connection.
  • the door leaves are positioned in relation to one another and are stably mounted.
  • the first scissor-type 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 connected in an articulated manner to a second fitting part, the first scissor-type lever can move along the guide device when the folding door is opened and closed, which is reflected in reflected in a compact design.
  • the guide device creates some of the degrees of freedom that the scissor mechanism requires in order to be able to fold it together when moving between the open and closed positions.
  • the contact section can move along the cam as soon as the scissor mechanism is in the corresponding position. Pivoting of the second scissor-type lever can be produced by the contact between the contact section and the cam, with the first scissor-type lever being able to be carried along due to the pivoting of the second scissor-type lever due to the articulated connection between the scissor-type levers.
  • the control curve thus not only moves the scissor mechanism, but also offers the degrees of freedom that the scissor mechanism requires for folding and unfolding. Using the control curve, it is possible to position the door leaves in the desired position in relation to one another. The control curve thus defines the path of the scissor mechanism and also the path of the door leaves to one another.
  • an energy accumulator 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 leaf out of the closed position therefore no longer has to be applied by the user. This initiates the movement, for example by tapping the door or pressing against a certain position; however, the door leaves then open automatically to a certain extent.
  • the energy store can be charged by manual actuation in order to be able to discharge it, for example, when the door is opened again.
  • the force accumulator is arranged to act on the fitting between the first and the second scissor-type lever and/or between the first and/or second scissor-type lever and the intermediate lever, there is a direct introduction of force into the scissor-type mechanism.
  • the lift mechanism is installed compactly, which is reflected in the space-saving design of the ejection device.
  • the force is applied directly and not indirectly via other levers or anything else. There are other components avoided, the for example, can wear out or could be damaged.
  • the energy accumulator is formed by a spring—preferably a compression spring.
  • the second scissors lever If the contact section of the second scissors lever can be pressed against the control cam due to the action of the force accumulator, the contact section being movable along the control curve, the second scissors lever is moved against the control cam due to the introduction of force from the force accumulator. Through this movement and the contact with the first scissors-type lever, the scissors mechanism is forced to convert this introduction of force from the energy accumulator into a movement against the cam and against the first scissors-type lever. Conversely, a movement of the scissors mechanism against the control cam of the force accumulator is loaded in a certain operating position of the ejection device. The unloading and loading of the force accumulator thus takes place via the control cam and the contact of the contact section on the second scissor-type lever.
  • the length of the second scissor-type lever is variable, which occurs when the length of the second scissor-type lever changes in one direction direct implementation of the movement of the scissors mechanism and results in unloading and loading of the energy store. If the length of the second scissor lever and/or the length of the force accumulator attached to the second scissor lever changes due to the When the energy store is relieved, the scissor mechanism is put into operation and a supporting movement of the door leaf out of the closed position is generated.
  • control cam has an opening section and a clamping section, with the contact section - preferably formed by a second scissor lever rotatably mounted rolling element - being movable along the opening section and the clamping section, the ejection movement of the scissor mechanism is activated via the contact section, which moves along the opening section of the control cam made, whereby the folding door is opened. If the folding door is moved further 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.
  • a locking device is provided for locking the energy storage device, with the energy storage device being able to be tensioned by the interaction of the control cam and the contact section, and the energy storage device being locked in the tensioned state by the locking device, as a result of which the energy storage device can be prevented from being discharged .
  • the energy store in connection with the relative position between the contact section and the control cam, the energy store can be discharged and charged. When charged, the energy store can be locked, which prevents the energy store from automatically discharging. The energy store can be triggered and discharged if this is done by the user is desired. Accidental discharging of the lift mechanism is impossible.
  • a triggering device which unlocks the locking device in a triggering position, so that the force accumulator can be changed from the charged to the discharged state, the opening of the folding door is forced by this triggering device.
  • This triggering device can be a connecting element, for example, which at least temporarily connects the ejection device to another component of the piece of furniture or the body of the piece of furniture as soon as the user presses against the folding door, for example.
  • the trigger device can also be a push button or something comparable, which can be operated directly by the user. This makes it possible to covertly attach the triggering device to the piece of furniture.
  • the triggering device can obviously also be arranged on the piece of furniture.
  • the triggering device can be moved from a substantially coplanar position of the door leaves into the triggering position when the triggering device is pressed, it can be arranged in a concealed position on the piece of furniture. Pushing against the door leaves and over-pushing their coplanar position activates this trigger and forces the folding door open. This is also achieved in that the triggering device can be moved into the triggering position when the triggering device is pressed against the furniture body.
  • the concealed position of the triggering device is also achieved in that the at least one locking device can be unlocked when the ejection device is mounted 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.
  • a piece of furniture with a furniture body, at least one folding door, which comprises at least two door leaves connected to one another by articulation, has proven to be advantageous, with 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 leaves enclose an angle other than 180° to one another, and at least one ejection device.

  • figure 8 shows how the scissor mechanism 10 behaves when the second fitting part 1b is pivoted further in order to load the energy accumulator 14.
  • the charging of the force accumulator 14 takes place via the contact section 15, which is now located 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 is forcibly guided Contact section 15 moves on the control cam 13 along the clamping section SA, which leads to a clamping of the energy accumulator 14. Parallel to this, the scissors mechanism 10 can continue to move in order to figure 8 to bring door leaves 3a, 3b, not shown, into their open position (parallel position).
  • figure 9 shows how the in the figure 9 not visible folding door 3 is brought further in the direction of the open position.
  • the contact section 15 is located just before the most pronounced area of the cam 13 in the clamping section.
  • the force accumulator 14 is thus just before its most tightened position.
  • the locking device 16 is close to the locking point.
  • the scissor mechanism 10 is folded up further and takes its place between the door leaves 3a, 3b, which cannot be seen in the figure.
  • a small spring 59 in the pivoting area of the locking device 16 pushes it primarily into the locked position in order to ensure secure locking as soon as the Lay locking sections 16a, 16b positively one on top of the other or in one another.
  • FIG figure 10 shows the ejection device 1 shortly before the open position, which is the parallel position in FIG figure 10 not shown folding door 3 essentially corresponds.
  • the contact section 15 has arrived just before the end of the clamping section SA of the cam 13 .
  • the force accumulator 14 is almost completely tensioned. Due to the fact that the locking device 16 has moved away from the triggering device 17 along the longitudinal axis of the energy accumulator 14, triggering cannot take place in the parallel position of the door leaves 3a, 3b either. It is thus provided in the parallel position of the door leaves 3a, 3b no contact of the triggering device 17 with the locking device 16, since no unlocking of the energy store 14 is desired in the open position.
  • figure 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 in a substantially parallel position relative to the second door leaf 3b.
  • the ejection device 1 is now in the folded state between the door leaves 3a, 3b.
  • the spring accumulator 14 is fully tensioned.
  • the locking device 16 is closed due to the corresponding locking sections 16a, 16b.
  • the ejection device 1 During the movement from the open position to the closed position, the ejection device 1 is virtually idle and moves in the tensioned state from the open position to the closed position in order to be able to ensure renewed triggering.
  • the guide element 12b When the ejection device 1 is completely folded up, the guide element 12b is located at the end of the guide device 12.
  • figure 12 shows the ejection device 1 pivoting back from the open position into the closed position.
  • the guide element 12b of the first scissor lever 10a is thereby moved along the guide device 12 .
  • the scissor mechanism 10 remains in the folded state since it is latched by the locking device 16 .
  • the locking device 16 remains closed via the locking sections 16a, 16b.
  • the force accumulator 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 cam 13.
  • FIG 13 shows the ejection device 1 shortly before the coplanar position (closed position) of the door leaves 3a, 3b.
  • the scissors mechanism 10 still remains in the folded state. It can be seen that the triggering device 17 moves closer to the locking device 16 in order to be able to ensure a renewed triggering in the coplanar positions.
  • the contact section 15 is thereby moved away at a distance from the cam 13 and does not engage with it.
  • figure 14 shows the ejection device 1 in the coplanar position of the folding door 3. It is noticeable that the triggering device 17 is not yet in engagement with the locking device 16. Re-triggering is therefore not yet possible. This is due to the push-through protection, which is intended to prevent the door from being immediately reopened by the closing movement and exceeding the coplanar position. A time delay in the intervention of the triggering device 17 in the locking device 16 should therefore take place. This is done via the control device 61, which causes a time-delayed readjustment of the triggering device 17.
  • the control device 61 can be designed, for example, in the form of a damper, rotary damper or the like. This requires longer to readjust the triggering device 17 than the closing process of the door leaf 3.
  • FIG 15 shows how the push-through protection has been canceled via the control device 61 .
  • the triggering device 17 was correspondingly brought into engagement with the locking device 16 in order to be able to ensure that the ejection device is triggered again.
  • Re-triggering begins as soon as the pushing through occurs beyond the coplanar position of the door leaves 3a, 3b, as in FIG 4 shown.
