Sliding support for a shower rail

Abstract

A sliding shower support for shower rails comprises a main body holding a shower, said main body being suitable for connection to a guide rail so that it runs along the same rail, and releasing stop systems to lock the main body in a position along the guide rail. The stop systems comprise a cam which elastically grips onto the guide rail to lock it in place due to friction, in which the cam is made so that it grips onto the rail in the event of a first movement of the shower in a first direction to prevent this first movement and reduce the friction in the event of a second movement of the shower support in a second direction, opposite to the first, to allow this second movement of the shower support.

1 . A sliding shower support for shower rails comprising a main body, for supporting a shower and suitable for connection to a guide rail in such a way as to allow the movement of the shower support along the guide rail, and of releasing stop systems to lock the main body in a position along the guide rail, wherein said stop systems comprise a cam, which rests elastically against the guide rail gripping it using friction, the cam being made in such a way as to grip onto the rail at the first movement of the shower support in a first direction to stop such movement and reduce the friction in the event of a second movement of the shower support in a second direction, opposite to the first, to allow this second movement of the shower support.  
   
   
       2 . A sliding shower support in accordance with  claim 1  in which, due to friction between the cam and the guide rail, during the first movement of the shower support, the cam is moved in the second direction compared with the main body and, during the second movement of the shower support, the cam is moved in the first direction compared with the main body, and in which the cam is shaped and supported by the main body in such a way that: 
 with the movement of the cam in the first direction compared with the main body the cam moves towards the guide rail, increasing the friction, to automatically prevent the second movement of the shower support.    
   
   
       3 . A sliding shower support in accordance with  claim 2 , in which the cam is supported by the main body rotating around a rotational axis.  
   
   
       4 . A sliding shower support in accordance with  claim 3 , in which the cam has, in the direction of movement of the shower support a substantially convex shape, rounded or curved towards the guide rail.  
   
   
       5 . A sliding shower support in accordance with claims  4 , in which the cam has a circle sector shape with the geometric centre in the rotation axis and the axis is shifted, compared with a point of contact between the cam and the guide rail, in the direction of movement of the cam compared with the main body which produces the automatic lock of the shower support.  
   
   
       6 . A sliding shower support in accordance with  claim 5 , comprising release systems to release the cam from the guide rail and enable the movement of the shower support along the guide rail in the second direction.  
   
   
       7 . A sliding shower support in accordance with  claim 6 , in which the release systems comprise two buttons or cursors for manually releasing the cam, these two buttons or cursors being positioned on two substantially opposite sides of the main body.  
   
   
       8 . A sliding shower support in accordance with  claim 7 , comprising a central element rotationally supported inside the main body and equipped with a first portion, facing towards the guide rail and holding the cam as well as a second, fork-shaped portion with two substantially parallel levers, the ends of which constitute the two release cursors or buttons.  
   
   
       9 . A sliding shower support in accordance with  claim 8 , comprising a preloaded spring, acting between the main body and the cam to elastically press the cam against the guide rail.  
   
   
       10 . A sliding system for showers, comprising a guide rail suitable for fastening to a wall using special fastenings and a sliding shower support comprising a main body, for supporting a shower and suitable for connection to a guide rail in such a way as to allow the movement of the shower support along the guide rail, and of releasing stop systems to lock the main body in a position along the guide rail, wherein said stop systems comprise a cam, which rests elastically against the guide rail gripping it using friction, the cam being made in such a way as to grip onto the rail at the first movement of the shower support in a first direction to stop such movement and reduce the friction in the event of a second movement of the shower support in a second direction, opposite to the first, to allow this second movement of the shower support.
