Abstract: A floor assembly, such as a bowling floor, is supported above a sub-floor by telescoping pedestal supports that are vertically extendable and vertically retractable. Upper and lower ends of the pedestal supports are fixed to the floor assembly and the sub-floor, respectively, so that when a pedestal support is vertically retracted, a downward force will be applied to the floor assembly, for removing bulges in the floor assembly for example.
Abstract: The invention relates to a floor comprising a flooring (7, 8, 9), a system of load-bearing beams (5, 6) and pedestal supports (4, 4?), which are adapted to support the beams and the subfloor at a distance above a subfloor (2, 3). The pedestal supports are telescopically, continuously adjustable in the longitudinal direction before as well as after installation of the floor and are non-rotatably connectible to the beams as well as to the subfloor and capable of absorbing compressive as well as tractive forces in such a manner that, in the longitudinal adjustment, it is made possible to push the flooring away from the subfloor as well as pull it towards the same. The invention also relates to a pedestal support (4, 4?) for use in such a floor. Preferably, the floor is a bowling floor.
