Self-contained lifting module for the mobile bottom of a swimming pool

Abstract

A lifting module for the mobile rigid bottom of a swimming pool, including: a) a driving housing controlling the immersion and lifting movements at a single point of the mobile bottom; b) at least one peripheral guiding member of the mobile bottom; c) at least one transmission member connected to the driving housing on the one hand and to the single point of the mobile bottom on the other hand, the lifting module being totally self-contained in that it is free of any mechanical link with any other lifting apparatus acting at another lifting point of the mobile bottom.

1 . A lifting module for the mobile rigid bottom of a swimming pool, comprising:
 a) a drive housing controlling the immersion and lifting movements at a single point of the mobile bottom;   b) at least one peripheral guiding element of the mobile bottom ( 3 );   c) at least one transmission element connected to the drive housing on the one hand, and to said single point of the mobile bottom on the other hand;   
     the lifting module being completely self-contained in that it is free of any mechanical link with any other lifting means acting at another lifting point of the mobile bottom. 
   
   
       2 . The lifting module according to  claim 1 , characterized in that the drive housing comprises an electrically driven motor, connected to the transmission element by driving means such as a set of pulleys or accessories or reduction means, in order to bring about the immersion or the lifting of the mobile bottom in the swimming pool. 
   
   
       3 . The lifting module according to  claim 1 , characterized in that the drive housing comprises an electrically driven motor, connected to the transmission element by driving means such as a set of pulleys or accessories, in order to bring about the immersion or the lifting of the mobile bottom in the swimming pool. 
   
   
       4 . The lifting module according to  claim 1 , characterized in that the guiding element is a rail having the general shape of a profile arranged substantially vertically along a vertical wall delimiting the pool of the swimming pool, the mobile bottom being provided with at least one of cooperating peripheral sliding and winding means supported on one surface of the rail. 
   
   
       5 . The lifting module according to  claim 4 , characterized in that the guiding element is suspended at its top end by a mounting plate fixed to a top edge of the swimming pool, constituted in particular by a structural element and/or a curb. 
   
   
       6 . The lifting module according to  claim 5 , characterized in that the guiding element is not fixed to the vertical wall against which it is arranged. 
   
   
       7 . The lifting module according to  claim 4 , characterized in that the guiding element is made of stainless material and comprises a foam coating on a surface facing the vertical wall, so as to ensure it a non-aggressive contact with the latter. 
   
   
       8 . The lifting module according to  claim 4 , characterized in that the section of the guiding element is corrugated in shape and provided with a central reinforcement cooperating with the sliding and/or winding means of the mobile bottom, the reinforcement being edged with lateral bosses ensuring the guiding of the mobile bottom in the reinforcement. 
   
   
       9 . The lifting module according to  claim 1 , characterized in that the transmission element is constituted by a “marine” type strap. 
   
   
       10 . The lifting module according to  1 , characterized in that a guide pulley is arranged at least one of in the upper part of the guiding element and on the mounting plate, the transmission element connecting the drive housing to the lifting point running over this guide pulley. 
   
   
       11 . A lifting installation for the mobile rigid bottom of a swimming pool, comprising: several lifting modules arranged at several separate lifting points of the mobile bottom, distributed around the periphery of the latter. 
   
   
       12 . The lifting installation according to  claim 11 , characterized in that it comprises a device for adjusting and synchronizing the operation of the different lifting modules. 
   
   
       13 . The lifting installation according to  claim 12 , characterized in that the adjustment and synchronization device is adapted to produce different lifting or immersion travels for the respective different lifting points of the mobile bottom, so that the latter can be placed against the bottom of the swimming pool whatever the angle of inclination of the floor of the swimming pool. 
   
   
       14 . A swimming pool comprising: a mobile rigid bottom including a lifting installation of the mobile bottom according to  claim 11 , at least one drive housing being mounted on an upper edge of the swimming pool, such as at least one of a structural element or a curb, so that said drive housing protrudes beyond this upper edge. 
   
   
       15 . A swimming pool comprising: a mobile rigid bottom and including a lifting installation of the mobile bottom according to  claim 11 , at least one drive housing being mounted outside an upper edge of the swimming pool, so that at least part of the drive housing is buried in the ground substantially flush with said upper edge.
