Description

[0001] The present invention relates to a coupling plate for a built-in unit of a recreational vehicle, a coupling bracket for coupling a built-in component to a side wall of a recreational vehicle, a built-in unit and a use of a coupling plate.

[0002] Currently, built-in components, such as refrigerators, have very limited options for being securely and reliably attached to an adjacent structure in a recreational vehicle, such as a motorhome. When this option exists, it is typically found on the sides of refrigerators, resulting in specific requirements for furniture construction to ensure secure fastening, which may be relevant for homologation. In some cases, the built-in components may also have openings for bolting them to the base of the component's housing.

[0003] To ensure the safe installation of a built-in component, such as a refrigerator, in a recreational vehicle, coupling it to a structurally load-bearing part of the recreational vehicle's body can be advantageous, so that in the event of an impact, such a built-in component remains in its installed position.

[0004] The invention describes a coupling plate for a built-in unit of a recreational vehicle, a coupling bracket for coupling a built-in component to a side wall of a recreational vehicle, a built-in unit, and a use of a coupling plate, according to the features of the independent claims. Advantageous embodiments are the subject of the dependent claims and the following description.

[0005] According to one aspect of the invention, a coupling plate for a built-in unit of a recreational vehicle is proposed. The coupling plate has a base structure, which is plate-shaped in certain areas, and is configured to form a bottom surface for the built-in unit. Furthermore, the coupling plate has at least one receiving device, which is mechanically coupled to the base structure and is configured to interact with a corresponding receiving device in order to mechanically couple the corresponding receiving device to the coupling plate, and in particular to mechanically couple a built-in component to the coupling plate by means of the corresponding receiving device.

[0006] Advantageously, the coupling plate has at least one side coupling element, wherein the side coupling element is mechanically coupled to the base structure, and the side coupling element is configured to be mechanically coupled to a side wall of the installation unit;

[0007] Particularly advantageously, the coupling plate has at least one fastening element that is mechanically coupled to the base structure. The fastening element is designed to be coupled to a structurally load-bearing part of the recreational vehicle.

[0008] In particular, the at least one fastening element may have a pin, especially a cylindrical one, which is designed to be positively coupled to the structurally load-bearing part of the recreational vehicle.

[0009] Alternatively or additionally, at least one fastening element has a frame-shaped structure designed to couple the coupling plate to the structurally load-bearing part of the recreational vehicle at a distance.

[0010] The frame-shaped structure can be designed to be arranged within the installation unit, in particular to provide the largest possible free volume below the coupling plate.

[0011] In particular, the frame-shaped structure may consist predominantly of plastic or predominantly of metal, especially to improve the stability of the frame-shaped structure.

[0012] The at least one receiving device can be shaped as a corresponding receiving device corresponding to an insertion tab for a foot element. The insertion tab can, in particular, be configured to be positively coupled and / or detachably coupled to the foot element.

[0014] Alternatively or additionally, the insertion tab may have a locking element designed to interact with the foot element of the installation component to prevent the foot element from unintentionally detaching from the insertion tab.

[0015] Each of the receiving devices described in this specification can be mechanically coupled to the base structure by means of a screw connection.

[0016] In particular, the coupling plate may have a stop strip arranged at a rear edge of the base structure, and which is designed to at least partially encompass the installation component in the installation unit.

[0017] According to one aspect, it is proposed that at least one receiving device be designed in accordance with a rail. The rail can, in particular, be designed such that a coupling element of the installation component can interact with the rail to mechanically couple the installation component to the coupling plate, especially in a positive-locking and / or detachable manner.

[0018] In particular, at least one rail can extend over a predominant part of the extent of the base structure.

[0019] Alternatively, at least one rail can be designed in at least two sub-areas in such a way that the coupling element of the installation component can interact with the rail, particularly in these two sub-areas, for a positive-locking and / or detachable coupling.

[0020] Advantageously, the rail can have a bridge coupled to the base structure on one side, at the open end of which at least one shoulder is formed into which the coupling element of the installation component can engage in order to mechanically couple the installation component with the coupling plate.

[0021] The structurally load-bearing part of the recreational vehicle can be a floor panel, a running board, a ladder frame, a chassis mounting point, or a battery housing mounting point. Specifically, the floor panel can have an insert in a section that connects to the coupling plate to improve the connection between the coupling plate and the floor panel. This insert can have mechanical properties that enhance this connection. For example, the insert can be made of a foam material that is denser than that used in other areas of the floor panel, and / or the insert can be made of wood.

[0022] In particular, the built-in component can be a refrigerator, preferably a compressor refrigerator.

[0023] Particularly advantageously, at least part of the at least one mounting device or the entire at least one mounting device can be integrated as a metallic insert into a structure of the coupling plate. This allows a coupling force, which can be generated, for example, by accelerating the installation component, to be introduced and / or distributed into the coupling plate and / or into the structurally load-bearing part of the recreational vehicle in order to securely fix the installation unit and / or the installation component.

[0024] According to one aspect, it is proposed that the base structure and at least one receiving device are integral structures of a one-piece manufactured coupling plate.
