Description

State of the art

In the furniture sector, guide devices such as furniture hinges or flap fittings are known to enable a piece of furniture to be moved relative to a furniture body. Such guide devices are known, for example, from WO 2017/219054 A1 and the WO 2011/011800 A2 known.

The guide means must meet different requirements, for example the movement guide should make the interior of the furniture body or the movable furniture part accessible in order to be able to store objects in it or remove them from it.

In particular, mounting the furniture part to the guide means is associated with a comparatively high risk of injury in the case of known flap fittings due to the comparatively strong spring effect.

Object and advantages of the invention

The object of the present invention is to improve a device for moving a furniture part mounted on a furniture body of a piece of furniture, in particular to make it comparatively safe.

This problem is solved by independent claim 1.

The dependent claims address advantageous and expedient developments of the invention.

The invention is based on a device for moving a furniture part received on a furniture body of a piece of furniture, wherein the device has guide means, wherein when the device is mounted on the furniture, the furniture part can be moved with the guide means from a closed position relative to the furniture body into an open position relative to the furniture body and back, wherein the furniture part in the closed position assumes a position moved towards a front side of the furniture body, wherein a guide means is designed as an articulated lever, wherein the articulated lever is designed to be detachably arrangeable on mounting means of the device, wherein the mounting means can be mounted on the furniture part.

The device is designed, for example, as a pivot fitting or as a flap fitting for a piece of furniture. The piece of furniture is, for example, in the form of a top flap of a piece of furniture. The piece of furniture, in particular the furniture body, is designed, for example, as a wall cupboard.

Advantageously, the furniture part in the closed position assumes a position that is as close as possible to the front of the furniture body. For example, an opening in the furniture body is at least partially closed in the closed position. Advantageously, there is a distance, in particular a gap, between the furniture part and the furniture body in the closed position. The gap can be used to implement, for example, a touch-latch automatic opening mechanism on the furniture, which can form part of the device, for example.

The essence of the invention is that the guide means comprise a safety element, whereby the The securing element is movably arranged on the articulated lever and can be positioned relative to the articulated lever, wherein in a first position of the securing element a pivoting range of the guide means is limited by the securing element so that the guide means cannot be moved into the closed position during a closing movement from the open position, wherein in a second position of the securing element the pivoting range of the guide means is released so that the guide means reach the closed position during the closing movement from the open position. This prevents, for example, the device from being closed when it is mounted on the furniture body but when the furniture part is not yet mounted and/or when the mounting means on the guide means are not yet mounted, thereby advantageously avoiding the risk of injury from opening the device without the furniture part mounted.

Advantageously, in the first position of the securing member, a pivoting range of the guide means is limited by the securing member such that, in the mounted state of the device on the furniture, the mounting means and/or the furniture part does not reach the maximum position moved to the front of the furniture body in a closing movement, wherein in the second position of the securing member, in the arranged state of the device on the furniture, the mounting means and/or the furniture part can reach the maximum position moved to the front of the furniture body in the closing position.

The securing element is movable relative to the articulated lever. For example, the securing element is moved together with the articulated lever during an opening or closing movement of the guide means. Preferably, when the guide means are mounted on the mounting means, the securing element in the second position does not protrude beyond an outer edge of the articulated lever in the direction of the mounting means. The edge is in particular an edge of a large flat side of the Articulated lever, in particular an edge of a large flat side of an articulated arm of the articulated lever.

The guide means advantageously comprise a first and a second articulated lever, the first and the second articulated lever being connected to one another in an articulated manner, the first articulated lever being designed in a sandwich-like manner with at least two articulated arms, so that the second articulated lever is movably accommodated between the two articulated arms of the first articulated lever. Due to the sandwich-like arrangement, the articulated levers or the articulated arms of the articulated levers of the device are comparatively slim. The sandwich-like design of at least one articulated lever also enables a comparatively central introduction of force from the articulated lever to the housing.

It is also advantageous that the safety element is arranged so that it can move between the two articulated arms of an articulated lever. For example, the safety element is movably mounted on each articulated arm of the articulated lever. This means that the safety element is advantageously located on the guide means and is invisible to an observer.

It is also proposed that the safety element on the articulated lever is arranged in particular so that it can only pivot. Preferably, the safety element on the articulated lever is arranged in particular so that it can only rotate. It is also conceivable that the safety element is present on the articulated lever in particular so that it can only move linearly. In the case that the safety element is arranged in particular so that it can pivot on the articulated lever, the safety element can be relatively simple and easy to move, for example via a lever effect.

Advantageously, the safety element is provided as a lever element, e.g. in the form of a lever arm. For example, the lever element comprises a lever axis, wherein the The lever element is arranged to be pivotable, for example, via a pivot bearing on the articulated lever, the pivot bearing being formed along the lever axis on the lever element. For example, the lever element extends along the lever axis over a lever length, the pivot bearing being arranged offset from a center of the lever length on the lever element.

The guide means have a spring element in the form of a spring, the spring element being designed such that the safety element is urged into the first position by the spring element under spring load. The safety element is, for example, spring loaded by the spring element. It is also conceivable that the guide means are provided in such a way, in particular that the safety element is provided in such a way that the gravitational force of the earth moves the safety element into the first position.

For example, the guide means are designed to be self-locking, so that the guide means cannot be moved into the closed position without external intervention, e.g. intervention by the assembly means. As a result, the guide means are automatically secured, so that the guide means cannot be moved into the closed position without external intervention, e.g. intervention by the assembly means.

It is further proposed that the spring element is designed as a leg spring. Preferably, the spring element is designed as a spring, e.g. as a helical spring, a torsion spring, a leaf spring, in particular as a leg spring.

In an advantageous embodiment of the device, the securing member is arranged on a first articulated lever of the guide means and, in the first position, couples with a second articulated lever of the guide means, so that the guide means, during a closing movement from the open position, cannot be moved into the closed position. In particular, the coupling of the safety element to the second articulated lever limits a relative movement of the first articulated lever to the second articulated lever in the first position. For example, the safety element in the first position blocks a movement of the second articulated lever, in particular relative to the first articulated lever.

A connecting element is present on the mounting means, wherein the connecting element can be arranged on a locking means, wherein the locking means is formed on an articulated lever of the guide means, wherein in the connected state of the guide means with the mounting means the connecting element urges the securing member from the first position into the second position, so that the pivoting range of the guide means is released and the guide means reach the closed position during the closing movement from the open position.

The locking means connects, for example, the two articulated arms of the first articulated lever to one another. An element of the locking means is designed, for example, as a bolt, a pin and/or a rivet. The connecting element advantageously surrounds the element of the locking means in the arranged state. The connecting element advantageously has a receptacle. The receptacle is, for example, C-shaped or U-shaped. Preferably, the connecting element with the receptacle surrounds the element of the locking means. The element of the locking means is only linearly movable on the first articulated lever. The locking means comprise a spring element and the spring element applies a spring force to the element of the locking means and thus pushes the element of the locking means into a locking position with the connecting element in the arranged state.

It is also proposed that the securing member comprises a locking element which locks into the second articulated lever in the first position. The locking element is, for example, designed like a hook. The securing member is, for example, provided in one piece, wherein the securing member comprises the locking element. The locking element is, for example, formed at one end of the particularly elongated securing member.

It is also advantageous that the securing element has a stop element on which the connecting element acts when the guide means are connected to the assembly means, the stop element and the locking element being spaced apart from one another. The securing element is, for example, provided in one piece, the securing element enclosing the stop element. The locking element is, for example, formed on a further end of the, for example, elongated securing element.

Advantageously, the locking element and/or the stop member are integrally provided on the safety member. Advantageously, the stop member and the locking element are designed opposite one another. For example, the stop member is provided at a second end of the safety member and the locking element is provided at a first end of the safety member.

Furthermore, it is advantageous that the second articulated lever has a locking element which couples to the locking element of the securing element. The locking element is designed, for example, like a hook. For example, the locking element is present on the second articulated lever in particular in a nose-like manner, protruding from the second articulated lever.

For example, the locking element in the first position engages behind the locking member of the second articulated lever. For example, the locking element in the first position engages behind the Locking member of the second articulated lever such that a movement, in particular a rotational movement, of the second articulated lever relative to the locking element or securing member, in particular in a plane of movement of the guide means, in one direction, in particular in the closing direction of the second articulated lever, is blocked or locked.

It is also proposed that the locking member and the second articulated lever are provided as a single piece.

It also proves to be advantageous that the device has an emergency opening mechanism. For example, the device is designed to be movable into an open state by means of a user's mechanical intervention in the closed state, in particular when the furniture part is not mounted and/or when the mounting means are not mounted. In the unforeseeable event that the function of the safety element fails and the guide means are placed in the closed state without the mounting means mounted, the device is advantageously provided in such a way that the guide means can be moved back into an open state by a user.

An advantageous embodiment of a piece of furniture is a piece of furniture with a device for moving a furniture part received on a furniture body of the furniture according to one of the previously described embodiments.

Figure 1 shows in perspective a piece of furniture or a wall cabinet 1 according to the invention with a box-shaped furniture body 2 and a furniture part received thereon, which is designed as a plate-like upper flap 3, which is shown in an open position relative to the furniture body 2.

The furniture body 2 comprises two opposite, upright side walls 4 and 5, which are connected at the bottom to a base 6 and at the top to a top 7. The rear of the furniture body 2 is closed by a rear wall 8.

For moving the top flap 3 about a horizontal pivot axis relative to the furniture body 2 from the Fig.1 shown open position into a closed position (not shown) moved towards the front of the furniture body 2 on a front side 4b, there is a movement device according to the invention which is designed as a top flap fitting 9. The top flap fitting 9 has a first fitting unit 10 on the side wall 4 and a second fitting unit 11 on the side wall 5, which are constructed in the same way but side-related for functionally correct arrangement on the respective side wall 4 or 5.

Each fitting unit 10 and 11 comprises a base unit 12, guide means 13 with articulated levers and assembly means in the form of assembly units, each of which comprises a mounting plate 15a, 15b. The base unit 12 is connected to the mounting plate 15a, 15b via several articulated levers, which are present as swivel arms of a swivel arm arrangement 14, which is firmly attached to an inner side of the upper flap 3, e.g. countersunk in a material recess.

In Figure 3 the fitting unit 10 of the top flap fitting 9 is shown in a state in which it has not yet been mounted on the wall cabinet 1. For better understanding, parts of the fitting unit 10 have been kept transparent, including a side cover cap 16 and a lever arm of an articulated lever.

A first articulated lever 17 of the swivel arm arrangement 14 advantageously comprises a first articulated arm 18 and a second articulated arm 19, wherein the second articulated arm 19 in Figure 3 is kept transparent for a better understanding of the device. The two articulated arms 18, 19 of the first articulated lever 17 are advantageously identical. It is also conceivable that the articulated arms 18, 19 are mirror-symmetrical to one another.

A second articulated lever 20 of the swivel arm arrangement 14 advantageously comprises a single articulated arm. The second articulated lever 20 is movably mounted, for example, between the two lever arms 18, 19 of the first articulated lever 17. The first and second articulated levers 17, 20 are preferably movably connected to one another ( Figure 4 ).

For example, the first articulated lever 17 comprises two locking members in the form of bolts 21, 22. The bolts 21, 22 are advantageously arranged at a distance from one another on the articulated lever 17. For example, the bolts 21, 22 are present in a protruding manner on a lever arm 18, 19. For example, the lever arms 18, 19 are connected to one another by means of the bolts 21, 22. In particular, the lever arms 18, 19 are spaced from one another by the bolts 21, 22.

Furthermore, locking means in the form of a locking element 23 are formed on the first articulated lever 17, which can be moved linearly, for example by means of a guide member in the form of a guide contour 24. is present on the first articulated lever 17. The guide contour 24 is, for example, slot-like, in particular designed as a slot or as an elongated hole.

For example, a spring element in the form of a leg spring 25 is also arranged on the first articulated lever 17. The leg spring 25 is connected, for example, to the locking element 23. The leg spring 25 is held, for example, at a mounting point 26 on the first articulated lever 17.

For example, two connecting elements 27, 28 spaced apart from one another are formed on the mounting plate 15a. The connecting elements 27, 28 are formed, for example, so as to protrude from a surface 29 of the mounting plate 15a. For example, the connecting elements 27, 28 are provided in the form of hooks. Advantageously, one connecting element 27, 28 in each case engages around a bolt 21, 22 ( Figure 6 ). For example, during an assembly process of the mounting plate 15a, a first connecting element 27 is hooked onto the bolt 21 by means of a pivoting movement to the first articulated lever 17.

A safety element in the form of a safety lever 30 is advantageously arranged on the first articulated lever 17. The safety lever 30 is, for example, rotatably mounted on the first articulated lever 17 via a bearing 31. For example, the bearing 31 connects the first and second articulated arms 18, 19.

The safety lever 30 comprises, for example, a stop 32 at a first end and, for example, a locking element, e.g. in the form of a recess 33, at a second end.

The safety lever 30 is spring-loaded by the leg spring 25. The leg spring 25 grips, for example, the first end of the safety lever 30 on the safety lever 30. The second articulated lever 20 comprises, for example, a locking member in the form of a locking lug 34. The locking lug 34 is, for example, integrally provided on the articulated lever 20. The leg spring 25 advantageously urges the safety lever 30 into the first position, so that when the first and second articulated levers 17, 20 are in the appropriate position relative to one another, e.g. when the swivel arm arrangement 14 is in the open state, the safety lever 30 locks with the second articulated lever 20 or the locking lug 34.

The locking lug 34 and the recess 33 are advantageously matched to one another in such a way that the safety lever 30 with the recess 33 holds the locking lug 34 in a first position, as in Figure 4 shown. This blocks a movement of the second articulated lever 20 relative to the first articulated lever 17.

When mounting the mounting plate 15a on the first articulated lever 17 ( Fig.4 , 6 ), the connecting element 28, for example, strikes the stop 32 of the safety lever 30 and presses the safety lever 30 against the spring action of the leg spring 25 into a second position ( Fig.6 ). In the second position, the safety lever 30 is advantageously decoupled from the second articulated lever 20. This enables a relative movement of the second articulated lever 20 to the first articulated lever 17, whereby the swivel arm arrangement 14 can be moved from the open position ( Figures 1 , 5 ) in a closing movement to a closed position ( Figure 7 ) is movable.

In the unlikely event that the swivel arm assembly 14 is in the closed position and the mounting plate 15a is not mounted on the first articulated lever 17 ( Figure 7 ), the fitting unit 10 advantageously comprises an emergency opening function to move the pivot arm arrangement 14 from the closed position to an open position.

For this purpose, the fitting unit 10 has a functional opening 36 on a side wall 35, for example on the base unit 12. Through the functional opening 36, a fitter can, for example, use a screwdriver 37 to exert a force on another articulated lever 38 of the swivel arm arrangement 14 ( Figures 8, 10 ), so that the swivel arm arrangement 14 can be moved into an open position against a spring force of a spring assembly 39 of the swivel arm arrangement 14 ( Figure 9, 11 ), in which the fitter can grip the first articulated lever 17 and move the swivel arm arrangement 14 into a further, in particular fully open position. During this further movement, the swivel arm arrangement 14 is force-supported by the spring assembly 39 from a certain open position of the swivel arm arrangement 14 and is moved by the spring assembly 39 into the fully open position. This movement of the swivel arm arrangement 14 occurs comparatively quickly due to the force support of the spring assembly 39, which means a comparatively high risk of injury for the fitter.
