The present invention relates to a guide system for guiding at least one movable furniture part, in particular a door wing, in a direction extending parallel to at least one furniture wall. The guide system comprises at least one guide device for guiding the at least one movable furniture part, and the guide device being configured to guide the at least one movable furniture part with a predetermined distance to the at least one furniture wall.
Moreover, the invention relates to a gliding device for glidingly supporting a movable furniture part, in particular a door wing, on at least one, in particular stationary, furniture wall.
The invention further concerns an item of furniture comprising a furniture carcass, at least one movable furniture part, in particular a door wing, and at least one guide system and/or at least one gliding device of the type to be described.
WO 2018/129572 A1 discloses a guide system for moving two door wings hingedly connected to each other between a first position, in which the door wings are aligned substantially coplanar to each other, and a second position, in which the door wings are aligned substantially parallel to each other. In the second (parallel) position, the door wings can be countersunk within a lateral insertion compartment of the furniture carcass. The guide device includes a guide rail extending in a depth direction of the item of furniture, and a carrier for pivotally supporting a door wing. The carrier can be guided along the guide rail with a predetermined distance to a furniture wall. However, due to an excessive manual force application to the door wing in a direction extending transversely to the furniture wall, it may occur that a door wing collides with the furniture wall. As a result, the movement of the door wing is impeded or even blocked. Moreover, there is the danger that the door wings, the furniture wall and the components of the guide system can be damaged.
It is an object of the present invention to propose a guide system of the type mentioned in the introductory part and/or a compact gliding device for glidingly supporting the movable furniture part, thereby avoiding the above-discussed drawbacks.
According to a first variant of the invention, the guide system includes at least one gliding device separate from the guide device. The at least one gliding device is configured to be arranged on the at least one movable furniture part or on the at least one furniture wall such that the at least one movable furniture part and the at least one furniture wall can be brought into a gliding contact with each other via the gliding device when the predetermined distance becomes smaller.
In other words, according to the first variant of the invention, at least one gliding device is provided on which the movable furniture part, upon an excessive force application to the furniture part in a direction extending transversely to a longitudinal extension of the guide device, can be glidingly supported. In this way, the motion sequence of the movable furniture part can be harmonized and the movable furniture part, the furniture wall and/or the components of the guide system can be protected from damages.
According to a preferred embodiment, the at least one gliding device, in a condition in which the at least one movable furniture part is guided with the predetermined distance relative to the furniture wall, is without contact to the at least one movable furniture part or to the at least one furniture wall. In other words, a contact between the movable furniture part and the gliding device is only possible when the predetermined distance falls below a certain value due to a mechanical force application to the movable furniture part (for example in the case of misuse). This has the advantage that the movable furniture part and the gliding device only contact each other in an overload case. On the contrary, upon a movement of the movable furniture part with the predetermined distance to the furniture wall, no contact does occur. In this way, the frictional resistance can be considerably reduced upon a normal movement of the movable furniture part.
According to a second variant of the invention, a gliding device for glidingly supporting a movable furniture part, in particular a door wing, on at least one, in particular stationary, furniture wall is provided. The gliding device includes at least one movably-supported rolling body configured to support the movable furniture part. The gliding device includes at least one housing section configured to be at least partially countersunk within a, preferably cylindrical, recess of the movable furniture part or of the furniture wall.
In other words, according to the second variant of the invention, a gliding device with a housing section is provided, the housing section being configured to be partially countersunk within a recess, for example within a cylindrical bore, of the movable furniture part or of a furniture wall. This offers the possibility that the at least one rolling body of the gliding device can be partially countersunk within the furniture wall or within the movable furniture part. As a result, the gliding device can be designed significantly more compact, in particular flatter. Moreover, already existing hole grids for fixing the gliding device can be used which additionally increases the ease of assembly.
Preferably, the countersinkable housing section of the gliding device is configured to be arranged within a cylindrical bore which is usually provided in the furniture manufacture, preferably having a diameter of 35 mm. Such bores are usually also utilized for hinge cups of furniture hinges, and these bores can also be used so as to countersink the housing section of the gliding device.
Further details and advantages of the present invention will be apparent from the following description of figures, in which:
The movable furniture part 2 can be guided by a guide system 18 with a predetermined distance in a direction extending parallel to the furniture wall 3a, the guide system 18 comprising at least one guide device 4. In the shown embodiment, the guide device 4 includes a groove 4a and a guide element 4b configured to be partially engaged into the groove 4a.
For example, the groove 4a is arranged on the movable furniture part 2 and the guide element 4b is connected to a furniture wall 3a, 3b in a mounted condition. Preferably, the guide element 4b of the guide device 4 is arranged on at least one of the spacer members 5a, 5b.
The groove 4a can be formed on or in a U-shaped profiled rail, the profiled rail being fixed in a region of the upper edge and/or in a region of the lower edge of the movable furniture part 2. The profiled rail with the groove 4a can extend substantially over an entire depth of the movable furniture part 2.
For example, the guide element 4b can include at least one wedge and/or at least one rotatable running wheel. The guide element 4b is movable along the groove 4a upon a movement of the movable furniture part 2.
Due to an excessive mechanical force application to the movable furniture part 2 in a direction extending transversely to the furniture wall 3a, it may occur that the movable furniture part 2 can collide with the furniture wall 3a. By virtue of a gliding device 10 (
In the shown embodiment, two guide devices 4 are provided, and each of the guide devices 4 has a groove 4a. The grooves 4a are arranged in a region of the upper edge and in a region of the lower edge of the movable furniture part 2.
In the shown embodiment, the guide element 4b is in the form of a wedge, the wedge being arranged on the spacer member 5a. By the guide device 4 with the guide element 4b moving into the groove 4a, the movable furniture part 2 can be guided with a predetermined distance with respect to the furniture wall 3a.
According to an embodiment, the at least one insertion compartment 6 is defined by two furniture walls 3a, 3b spaced apart from each other.
