Pedestal support and floor constructed of such pedestal supports

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.

1 . A floor comprising:
 a sub-floor;   a floor assembly spaced above the sub-floor and including load-bearing beams and a flooring thereon; and   pedestal supports vertically telescopically adjustable and connected between the sub-floor and the floor assembly in such manner that the pedestal support applies upward force to the floor assembly when the pedestal support is extended vertically and applies downward force to the floor assembly when the pedestal support is vertically retracted.   
   
   
       2 . The floor as claimed in  claim 1  wherein upper and lower ends of the pedestal supports are rigidly fixed to the floor assembly and the sub-floor, respectively. 
   
   
       3 . The floor as claimed in  claim 1  wherein an upper end of the pedestal support is non-rotatable relative to the floor assembly. 
   
   
       4 . The floor as claimed in  claim 1  wherein each pedestal support comprises a holder fixedly connected to the beams and which is rotatably connected to a threaded rod which in turn is threadedly connected to a pedestal support body which is fixedly connected to the sub-floor. 
   
   
       5 . The floor as claimed in  claim 4  wherein the threaded rod has an engaging means allowing screwing of the rod into and out of the body by means of a tool. 
   
   
       6 . The floor as claimed in  claim 4  wherein the threaded rod has a lock nut which is tightenable against the body to lock the threaded rod relative to the body when the desired vertical length of the pedestal support is achieved. 
   
   
       7 . The floor as claimed in  claim 1  wherein the body comprises a base part directly fixedly connected to the sub-floor. 
   
   
       8 . The floor as claimed in  claim 1  wherein the flooring has at least one operable portion to allow access for adjustment of the vertical lengths of the pedestal supports. 
   
   
       9 . The floor as claimed in  claim 1  wherein the floor is a bowling floor. 
   
   
       10 . The floor as claimed in  claim 1 , wherein the sub-floor comprises a sound-insulating layer and, arranged thereon, a carrying layer on which the pedestal supports are supported. 
   
   
       11 . In a building comprising a sub-floor, vertical walls, and a floor assembly including load-bearing beams and a flooring thereon, the floor assembly being spaced above the sub-floor and supported thereby for up-and-down movement relative thereto, wherein the floor assembly constitutes a floating floor assembly which is separate from the walls, the building further comprising pedestal supports vertically telescopically adjustable and connected between the sub-floor and the floor assembly in such manner that each pedestal support applies upward force to the floor assembly when the pedestal support is extended vertically and applies downward force to the floor assembly when the pedestal support is vertically retracted. 
   
   
       12 . The building according to  claim 11 , wherein the flooring constitutes a bowling floor having a plurality of side-by-side lanes and respective pin platforms, the floor assembly further including gutters, each lane and associated pin platform being disposed between two of the gutters. 
   
   
       13 . The building according to  claim 12 , wherein each pin platform is separate from its respective lane and is adjustable up-and-down independently thereof by the pedestal supports. 
   
   
       14 . In a building comprising a sub-floor and a floor assembly including load-bearing beams and a flooring thereon, the floor assembly being above the sub-floor and supported thereby for up-and-down movement relative thereto, wherein the flooring constitutes a bowling floor having a plurality of side-by-side lanes and associated pin platforms, the floor assembly further comprising variable gutters, each lane and associated pin platform being disposed between two of the gutters, wherein adjustment devices are provided in a space disposed between the sub-floor and the floor assembly for applying a force to respective regions of the floor assembly, the improvement wherein each adjustment device comprises:
 a pedestal support vertically telescopically adjustable and connected between the sub-floor and the floor assembly in such manner that the pedestal support applies upward force to the floor assembly when the pedestal support is extended vertically and applies downward force to the floor assembly when the pedestal support is vertically retracted, wherein some of the pedestal supports are arranged in straddling relationship to the gutters and are accessible for adjustment when the respective gutters are raised.
