Description

Gear nut The invention relates to a gear nut for the gear of a fitting arrangement of a window, a door or the like, in particular a lift-and-slide element, such as a lift-and-slide door or a lift-and-slide window. Such gears for a lift-and-slide element are known, for example, from DE 10 2019 109 639 A1 or DE 10 2019 109 642 A1, where the gear nut of these gears is referred to as the input shaft. However, fitting assemblies for windows or doors whose sashes are opened by turning can also have similar gears that include a corresponding gear nut. The gear nut is generally used to transmit manual actuation of an actuating element coupled to the gear nut, such as a handle, to an adjusting element of the respective fitting assembly, via which the fitting assembly can be adjusted between different states—for example, a locked or unlocked sash, or a raised or lowered sash. Typically, a rotational movement of the actuating element is converted into a translational movement of the adjusting element. The adjusting element can be, for example, a drive rod of the fitting assembly. Since the forces applied by manual operation are introduced into the fitting arrangement via the gear nut, it must be particularly stable. . Conventional gear nuts are therefore solid. In particular, it is common to manufacture the gear nut as a cast part. This allows for a high degree of strength of the gear nut. However, manufacturing is comparatively material- and energy-intensive. It is an object of the invention to provide a gear nut for the gear of a fitting arrangement of a window, a door or the like, in particular a lift-and-slide door or a lift-and-slide window, which can be produced comparatively easily and in a resource-saving manner and at the same time has reliable stability. The object is achieved by a gear nut with the features of claim 1 and by a gear with the features of claim 15. Advantageous embodiments emerge from the subclaims, the present description and the figures. The gear nut according to the invention is designed to be used in a gear of a fitting arrangement of a window, a door or the like, in particular a fitting arrangement of a lift-and-slide element, such as a lift-and-slide door or a lift-and-slide window. According to the invention, the gear nut comprises a receptacle for an actuating element, which extends along a central axis of the gear nut, and a coupling section which is eccentric with respect to the central axis for the drive-effective coupling of the gear nut to an actuating element of the fitting arrangement. Said receptacle preferably extends from the outside into the gear nut. In particular, the receptacle can extend through the gear nut. The mount then corresponds to a passage through the gear nut along the central axis. The central axis can run centrally through the receptacle. In particular, a cross-section of the receptacle perpendicular to the central axis can be rotationally symmetrical with respect to the central axis. In this case, the receptacle does not necessarily have to have the cross-section over its entire extent along the central axis. The cross-section of the receptacle can be defined by the largest cross-section that an element can have that is fully inserted into the receptacle along the central axis or pushed through the receptacle. Preferably, the cross-section of the receptacle has 4-fold rotational symmetry with respect to the central axis. In particular, the cross-section can be at least substantially square. The receptacle can be designed for the actuating element in such a way that the actuating element or at least a coupling section of the actuating element can be inserted into the receptacle, in particular along the central axis. Said actuating element can be, for example, a handle. The coupling section of the actuating element can be designed, for example, as a square rod. The receptacle can therefore be designed as a square receptacle. The coupling section of the gear nut serves to drive-effectively couple the gear nut with an actuating element of the fitting arrangement, so that an adjustment, in particular rotation, of the gear nut (by means of the actuating element) leads to an adjustment, in particular displacement, of the actuating element. Thus, a transmission of a drive movement from the gear nut to the actuating element takes place. The coupling section of the gear nut does not necessarily have to be directly coupled to the actuating element, but the transmission of the drive movement can also take place via one or more components provided between the coupling section and the actuating element. The adjusting element can, in particular, be a drive rod of the fitting arrangement. However, the adjusting element can also be formed by another adjustable mechanical element of the fitting arrangement. The respective position of the adjusting element can be decisive for the respective state of a sash of the window or door or the respective state of the lift-and-slide
