<p>#CMT# #/CMT# The cover has trestles presented in the form of arched transversal sections (1) provided with grooves on their both sides. A pair of lower-lateral flaps (3, 3`) is placed in the grooves and coupled to plates fixed corresponding to a zenith zone of the cover. The flaps slide on guides defined by the grooves such that the flaps set, at their turn, a lateral closure integral to a swimming pool. The top flaps move upwards to define a ventilation window, at the level of ground, while maintaining the closure at the lower level. #CMT#USE : #/CMT# Used for permitting access to users to the interior of a swimming pool (claimed) and for obtaining cumulated and condensed air to the interior of the pool. #CMT#ADVANTAGE : #/CMT# The top flaps move upwards to define the ventilation window, at the level of ground, while maintaining closure at the lower level, thus preventing the access of infants and pets to the swimming pool. The cover has a simple and inexpensive structure, while providing different closing levels. The flaps are moved towards the zenith zone without being superposed with each other while leaving the lateral part of the cover released over a great height. The material of the plates corresponding to the zenith zone supports the exterior condition effects in an undetermined manner. The plates have transparent nature so that the incident solar radiation is passed over the plates, and hence about the water temperature serving as a barrier to limit the loss of heat. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a front view in which the lateral plates are installed in a complete closing condition. 1 : Arched transversal sections 3, 3` : Lower lateral flaps 7 : Lower section 8 : Upper section 10 : Wing #CMT#POLYMERS : #/CMT# The plates are made of polymethacrylate.</p> |
