Description

translational-rotational fitting and furniture or household appliance element The present invention relates to a translation-rotation fitting according to the preamble of claim 1 and a furniture or household appliance element according to the preamble of claim 14. Translation-rotation fittings of this type are known, for example, from WO 2022/157295 A1 or DE 10 2019 109 866 A1. They serve to move a first body relative to an interface, for example a second body, in one of two opposite directions of rotation and simultaneously in a predetermined translation direction, in order to move the first body, for example from a corner area, from an initial position to a position rotated by 90° or a multiple of 90°, without hitting the walls defining the corner area. When transporting furniture fitted with such translational-rotational fittings, it is necessary that the furniture part that can be moved via the respective translational-rotational fitting, for example the first body, is secured in order to prevent this furniture part from moving accidentally during transport. Even if the translational-rotational fitting is transported separately, it is advantageous to prevent movement of the two fitting plates in order to prevent damage to them. Furthermore, it is advantageous if the translational-rotational fitting is secured against accidental movement of the fitting parts relative to one another before assembly. The object of the present invention is therefore to further develop a translational-rotational fitting in such a way that an unwanted movement of the furniture part or of a fitting plate during transport or during assembly is effectively prevented. A further object of the invention is to secure the translational-rotational fitting before assembly against an unintentional movement of the fitting parts relative to one another. This object is achieved by a translation-rotation fitting having the features of claim 1. The translational-rotational fitting according to the invention for at least partially forced simultaneous translational-rotational movement of a furniture part, for example a first body, relative to an interface, for example a second body, in one of two opposite directions of rotation and in a predetermined translational direction has a first fitting plate that can be fastened to the furniture part and a second fitting plate that can be fastened to the interface or the second body and can be moved simultaneously in translational and rotational directions relative to the first fitting plate. The furniture part can also be designed as a table, a platform for arranging several furniture parts or another furniture element. The interface can also be a wall surface of a building wall, for example. The translational-rotational fitting further comprises a securing element that can be detachably fastened to the first fitting plate and/or the second fitting plate, wherein in the assembled state of the securing element the fitting plates are fixed relative to one another by blocking the translational movement. With such a translation-rotation fitting, safe assembly and safe transport of a piece of furniture equipped with such a translation-rotation fitting is made possible in a simple manner. Advantageous embodiments of the invention are the subject of the subclaims. According to an advantageous embodiment of the invention, the translation-rotation fitting has at least one carriage guided on the second fitting plate along at least one carriage track extending in the translation direction, which is rotationally coupled to the first fitting plate. The securing element is designed as a blocking element that fixes the carriage in a starting position of the carriage track. By blocking the slide using the safety element, it is possible to prevent the entire translational-rotational movement at the same time, since the translational movement of the translational-rotational fitting is accompanied by the rotational movement and therefore sufficient security is created by blocking the translational movement. Alternatively or in addition, the safety element can also block the rotational movement. According to a further development of the translational-rotational fitting according to the invention, the securing element has a gripping area and a blocking area which fixes the carriage in the starting position of the carriage track. According to a first particular embodiment of the translation-rotation fitting according to the invention, the blocking region of the securing element is rod-shaped and can be inserted through an opening in the first fitting plate and in the second fitting plate into a positioning dome accommodated in a recess of a base support plate or cover support plate of the interface or the second body. The outer contour of the blocking area of the securing element is positively received in the openings. A safety element designed in this way is easy to manufacture and just as easy to install.
