Definitions

• the invention relates to a device with a base plate and a support for tool-free height adjustment of an assembly, in particular a kitchen module in an aircraft.
• the object of the invention is to provide a device for height adjustment of assemblies in aircraft, which allows a fast and tool-free and substantially continuous height adjustment of the assembly when installed in a fuselage structure of an aircraft without losing parts.
• an upper side of the substantially rectangular base plate at least partially on a base plate toothing.
• an upper side of the base plate at least partially a spring, in particular a dovetailed spring, which in each case in the region of lower sides of the wedge body arranged grooves, in particular dovetailed grooves, can be introduced, such that each wedge body parallel to Longitudinal axis of the base plate is guided displaceably.
• each locking lever in the region of a bottom at least partially has a detent lever toothing. Due to the intermeshing of detent lever toothing and base plate toothing when the detent lever is depressed, an uncontrolled horizontal displacement of the wedge body and thus a change in the height adjustment without active lifting of the detent lever is precluded.
• the gearing allows the base plate and the locking body an almost stepless or very finely graduated height adjustability of the device.
• the detent levers are each biased by a spring.
