Description

The present invention relates to a piece of furniture with a furniture body, on which a drawer and at least one inner drawer are movably held, wherein the inner drawer is at least partially hidden in a closed position by a front panel of the drawer, and the drawer at least a first ejection device after unlocking a Locking means of the first ejection device by moving a driven by a power storage carrier is ejectable, and the at least one inner drawer via at least one second ejection device after unlocking a locking device of the second ejection device by moving a driven by a power storage carrier is ejected, and a method for opening a Drawer and an inner drawer on a piece of furniture.

There are furniture with several drawers which can be ejected by means of drive devices with an electric motor ( AT 211 504 ). However, the use of such electric motors requires a laying of the power cable, which is relatively expensive, and also the permanent power consumption is disadvantageous.

The EP 1 901 633 B1 discloses a piece of furniture in which a drawer and an inner drawer are provided on a furniture body. The drawer and the inner drawer are each ejected via an ejector, which are interconnected via a switching element to couple the two ejectors and decouple. The switching element is part of a control or regulating device of the furniture, which increases the construction costs and makes a corresponding calibration required.

It is therefore an object of the present invention to provide a piece of furniture and a method for opening a drawer and an inner drawer to a piece of furniture, which ensure reliable opening of the inner drawer by simple means.

This object is achieved with a piece of furniture having the features of claim 1 and a method for opening a drawer and an inner drawer with the features of claim 11.

In the furniture according to the invention, a drawer can be ejected via a first ejection device, and at least one inner drawer via a second ejection device, wherein both ejectors have a driven by a power storage driver, and the locking device of the at least one first ejection device via mechanical synchronization means with the locking device of the at least one second ejector is synchronized. As a result, when opening the drawer always the inner drawer and the drawer are unlocked and ejected simultaneously. The use of mechanical synchronization means no electrical energy is needed, and also a high reliability is ensured.

The mechanical synchronizing means for simultaneously unlocking the first and second ejection means may comprise a rotatable rod to effect unlocking movement, in particular depression of the front panel of the drawer from a closed position to an overmold position. Instead of a rotatable rod and a sliding rod, a Bowden cable or other mechanical transmission means can be used, which cause a permanent coupling of the two unlocking devices.

An ejection section of the at least one first ejection device for the drawer is preferably larger than an ejection section of the at least one second ejection device for the inner drawer. This ensures that both the inner drawer and the drawer are accessible to the user after the initiation of an opening process, which simplifies handling. The ejection path of the inner drawer can be, for example, in a range between 10% to 70%, in particular 20% to 50% of the discharge path of the drawer.

In order to accommodate high weights on the drawer and to achieve a sufficiently large ejection distance, two first ejector devices may be provided for the drawer, which are mounted, for example, adjacent to a drawer guide. Optionally, the ejection device can be mounted on the drawer, for example on the underside of a floor or the frame of the drawer, or stationary on a holder of the furniture body. In any case, the movably driven driver causes an ejection of the drawer. Similarly, the inner drawer can be ejected with two ejectors that are either directly or indirectly fixed to the drawer or the furniture body. If the ejection devices are arranged so that they move relative to the furniture body, the coupling of the synchronization means between the drawer and the inner drawer is easily decoupled during the ejection process. When reaching the closed position of the drawer and the inner drawer the synchronization means between the drawer and the inner drawer are engaged again. The coupling can be formed by known form-fitting couplings, for example as a dog clutch or gear coupling.

Preferably, when unlocking one ejection device via the synchronization means, the other ejectors of the same drawer or inner drawer and the other ejectors of the drawer or inner drawer are unlocked.

For a particularly comfortable handling can be provided on the inner drawer and / or the drawer self-closing, which moves the drawer or the inner drawer in the closing direction in a closing area, in which case an energy storage of the respective ejection device by a movement of the inner drawer or the drawer in front of this closing area is charged. After charging the force accumulator this is locked so that then takes place in a closing area, a further closing movement of the drawer or the inner drawer. A corresponding mechanism for charging the energy storage device in combination with a self-closing is for example in the DE 10 2016 113 044 disclosed and can be used in the present ejection device.

In a further embodiment, the first ejection device for the drawer and the second ejection device for the inner drawer are designed to be identical, so that the variety of parts is reduced. For example, two identical right and two identical left ejectors can be used, two for a drawer and two for an internal drawer. If more than one inner drawer is provided, one or more ejectors may also be provided for each further inner drawer.

Preferably, an elastic stop or a brake is provided which slows down the inner drawer after a predetermined distance or limits the extension movement. Thereby, the distance of the inner drawer can be limited to obtain an offset of the drawer and the inner drawer during ejection, even if identical ejectors are used. Alternatively, the energy storage may be designed to be weaker in the ejector devices for the inner drawer than in the ejectors for the drawer. It is also possible to perform the power storage adjustable, so that the ejection widths of the drawer and / or inner drawer are adjustable.

In a method for opening a drawer and an inner drawer according to the invention, first, a front panel of the drawer is pressed from a closed position to an overpressure position to unlock a locking device of a first ejection device for the drawer, at the same time unlocking a locking device of a second ejection device for the inner drawer through mechanical synchronization means is effected. Subsequently, both the drawer and the inner drawer are ejected via the first or second ejector. Characterized the handling when opening the inner drawer is simplified, since only one movement is required to simultaneously open the drawer and the at least one inner drawer.

Preferably, the drawer is ejected over a longer distance than the inner drawer, so that both a storage space of the drawer and a storage space of the inner drawer are at least partially accessible.

A furniture 1 includes a furniture body 2 on which a drawer 3 and an inner drawer 5 are movably mounted. The inner drawer 5 is arranged concealed in a closed position, and a front panel 4 of the drawer 3 covers a front panel 6 of the inner drawer 5 Completely. It is also possible that on the furniture body 2 more than just an interior drawer 5 is movably mounted behind the front panel 4 is arranged concealed.

In 3 are the drawer 3 and the inner drawer 5 shown in a closed position, with only the front panel from the outside 4 is visible. Both the inner drawer 5 as well as the drawer 3 are about pullout guides 8th movably mounted, each at a bracket 7 on the furniture body 2 are mounted. To open the drawer 3 becomes the front panel 4 from the closed position into an overpressure position in the furniture carcass 2 pressed to unlock a locking device of an ejector.

In 4 is the furniture body 2 without the drawer 3 and the internal thrusts 5 shown, but with the four pullout guides 8th , Each of the drawer slides includes a stationary guide rail 9 , a middle rail 10 and a movable running track 11 , It is also possible to pull out guides 8th to use with only two rails or more than three rails.

On a pullout guide 8th for the drawer 3 is a stationary holder 80 fixed to which an ejector 12 is mounted. At the ejector 12 is a driver 13 mounted movably on a guide and with a coupling element on the drawer 3 or the running track 11 connectable to the drawer 3 eject in the opening direction. The two ejection devices 12 are about a rotatable rod 14 coupled together in order to unlock a locking device of an ejection device 12 also the locking device of the other ejection device 12 to unlock. This will make the drawer 3 simultaneously on opposite sides by a driven driver 13 ejected in the opening direction when a release has taken place.

The inner drawer 5 is also via an ejector 15 drivable, at the a driven driver 16 is guided linearly and with a coupling element on the inner drawer 5 or a running rail 11 at the inner drawer 5 can be coupled to make an ejection in the opening direction. The two ejection devices 15 are over a rotatable rod 17 coupled to each other at a release of a locking device of a discharge device and the unlocking of the other ejection device 15 to unlock.

In 5 are the pullout guides 8th and the ejectors 12 and 15 without the furniture body 2 shown. The first ejectors 12 for the drawer 3 are with the second ejectors 15 for the inner drawer 5 synchronized, so when unlocking the first two ejectors 12 also the second ejection devices 15 be unlocked. For this purpose, synchronization means are provided which comprise a vertical rotatable rod 21 include between two deflectors 20 is arranged. The deflection devices 20 are cup-shaped and can in a recess on a side wall of the furniture body 2 be inserted. At the deflection devices 20 becomes a rotation of the vertical bar 21 in a rotation of a shaft 19 causes the connection between the rotatable vertical rod 21 and the locking device of one of the ejection devices 12 or 15 manufactures. As a result, all four ejectors 12 and 15 synchronized with each other. The deflection device 20 can only be used on one side of the furniture. In this case, the ejectors are 12 of the drawer and the ejectors 15 of the inner drawer with a vertical bar 21 connected.

A release takes place by pressing in the front panel 4 in the closing direction, with the distance of the front panel 4 to the front panel 6 of the inner drawer 5 can be chosen so that no contact takes place and only the drawer 3 is moved in the closing direction, and at least one of the two first ejection devices 12 is unlocked, which then unlocks the other three ejectors on the synchronization means. Alternatively it is possible that the front panel 6 of the inner drawer 5 in the closed position on the front panel 4 of the drawer 3 rests so that by pushing in the front panel 4 at the same time the inner drawer 5 is moved in the closing direction, so that a second ejection device 15 can be unlocked first and then unlock the other three ejectors 12 and 15 is effected.

In 6 is an ejector 15 shown, which are identical to an ejector 12 can be trained. The ejection device 15 is stationary on the holder 80 arranged and has a biased by a power storage driver 16 on. On a housing of the ejection device 15 is a recording 95 for a wave 90 formed, which is rotatably mounted on the housing and a radially protruding projection 91 comprising a movable actuator of the ejection device 15 can press to unlock the ejection device 15 to effect. The ejection device 15 can be designed as in the DE 10 2016 113 044 is described. The lead 91 then acts there on the sliding actuator for unlocking. On the rotatable shaft 90 is a first protruding section 92 formed, which has a non-circular cross section and in a receptacle of the rotatable rod 17 can be plugged in to the pole 17 rotatably with the shaft 90 connect to. Also on the opposite side of the shaft 90 is a prominent section 94 trained with the shaft 19 rotatably coupled.

At each pullout guide 8th may also be provided a self-closing, the running rail 11 moves in a closing area in the closing direction and holds in the closed position. The self-closing mechanism can be damped, allowing a closing movement of the drawer 3 or the inner drawer 5 is slowed down and then takes place via the self-closing an automatic process in the closed position. A closing movement of the running rail 11 before the closing area can then for tensioning an energy storage of the ejection device 12 or 15 be used, as well as in the DE 10 2016 113 044 is described.

In 7 is a second embodiment of a piece of furniture 1 shown a drawer 3 and a movable inner drawer 5 having. As the 8th and 9 show is the inner drawer 5 over two pullout guides 8th and the drawer 3 also over two pullout guides 8th kept movable. The drawer 3 is about ejection devices 12 Ejectable while the inner drawer 5 over ejection devices 15 is ejectable. However, the synchronization does not take place via vertical bars 21 which are arranged in the region of a side wall or a receptacle of the side wall, but only by a single vertical rod 21 ' between two rotating rods 14 ' and 17 ' is provided. The rotatable rod 14 ' couples the two extension devices 12 of the drawer 3 with each other while the rotatable rod 17 ' the two second ejectors 15 of the inner drawer 3 connects with each other. The coupling of the rotating rods 14 ' and 17 ' thus does not take place over two spaced bars 21 but only over a single pole 21 ' attached to a rear wall or other vertical or horizontal traverse of the furniture body 2 is mounted. There are two deflections for this 20 ' provided, which are held with a cup-shaped housing on the rear wall or the crossmember. Other types of housing and holders are of course possible.

In 10 is a detail view of the connection of the rotatable rod 17 ' with the vertical bar 21 ' shown. The vertical bar 21 ' is at a warehouse 22 the deflection device 20 ' rotatably mounted and has end teeth, which engage with teeth of a transmission shaft 32 standing at a warehouse 23 the deflection device 20 ' is held. The transmission wave 32 has a gear at the end 31 on, which engages with a gear 30 stands, rotatably on the rotatable rod 17 ' is mounted. This will be via a rotary motion of the rotatable rod 17 ' also the transmission wave 32 turned, then the vertical rod 21 ' rotates and in the lower area over the further deflection device 20 ' another transmission wave 32 rotates and thus the rotatable rod 14 ' is turned. This causes the rods 14 ' and 17 ' synchronized.

In the illustrated embodiments are each two ejection devices 12 and 15 for ejecting a drawer 3 or an internal drawer 5 intended. Of course it is also possible to have only one ejector 12 or 15 provided. In addition, only an internal drawer 5 on the furniture body 2 It is also possible to do more than just an internal drawer 5 behind the front panel 4 of the drawer 3 to arrange.

The synchronization means are in the illustrated embodiments with rotatable rods 14 . 14 ' . 17 . 17 ' formed, which are rotatably coupled to each other via a gear. It is also possible to use Bowden cables or other gearboxes as synchronization means.
