Strut for lifting a roof element used to cover a swimming pool and installation method thereof

Abstract

The invention relates to a strut ( 300 a, 300 b, 300 c ) for lifting a roof element (I) and/or maintaining same in the open position, said roof element forming a swimming pool enclosure (A) that rests on the edge of the pool. The invention is characterised in that it includes a high end ( 310 a and 310 b ) hinged to the edge of a roof element (I) and a low end ( 320 a and 320 b ) joined to the ground by a securing means ( 400 ), so that it is possible to vary the position of the point at which the low end ( 320 a and 320 b ) of the strut ( 300 a and 300 b ) is joined to the ground. The invention also relates to the method for installing one such strut. The invention is suitable for swimming pool enclosures.

1 . Strut for the lifting and/or maintaining in open position of a roof element comprising a swimming pool shelter resting on the edges of a pool that it covers, the strut being of the type of that comprising a high end linked in articulation to the edge of a roof element and a low end linked to the ground, via a means of fastening, making it possible to vary the position of the point of linking of the low end of the strut in relation to the ground, characterized by the fact that said means of fastening is comprised of
 a flat surface bearing on the ground which is arranged with an extended orifice,   a bearing receiving a pivot pin of the low end of the strut,   a screw crossing said extended orifice and urged to become fixed to a hole arranged in the edge of the pool,   the screw taking three positions:   a first position of fastening by clamping of the screw head bearing against the means of fastening,   a second position of partial clamping where the means of fastening can slide over the ground according to a course of travel defined by the extension of the orifice without releasing itself from the screw,   a third position of unclamping where the means of fastening is released from the ground.   
   
   
       2 . Strut according to  claim 1 , characterized by the fact that said bearings define the support of an axis parallel to the edge of the roof element. 
   
   
       3 . Strut according to  claim 1 , characterized by the fact that said extended orifice is carried out between said two bearings. 
   
   
       4 . Strut according to  claim 1 , characterized by the fact that it is broken down into two foldable portions and of which the deployment and the folding are accompanied by a jack and by the fact that the point of articulation of the low end of the strut defined by the axis of said bearings is arranged higher than the point of articulation of the high end of the strut with the edge of the roof element. 
   
   
       5 . Strut according to  claim 1 , characterized by the fact that said extended orifice is comprised by a series of holes of the same diameter spaced and connected in relation to one another by a groove of a width less than said diameter. 
   
   
       6 . Strut according to  claim 1 , characterized by the fact that said pin is associated to a thumbwheel facilitating its manipulation. 
   
   
       7 . Strut according to  claim 1 , characterized by the fact that said screw cooperates with a spring sleeve occupying the hole made in the ground in such a way as to propose the position of partial clamping without an operation of unscrewing. 
   
   
       8 . Method of installing a foldable strut according to  claim 4 , the method comprising fixing the high end of the strut to the edge of the roof element, in fixing the low end of the strut to the ground and in sliding the means of fastening of the strut towards the shelter in such a way that the folded strut can be inclined towards the shelter.
