DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to a removable protective shelter for an activity or leisure area.
At present, an increasing number of installations used for different types of activities or for leisure purposes must be protected in particular from poor weather conditions, at least on a temporary basis, in order to ensure that the outdoor activity or leisure nature of these activities is maintained. This is the case for example of swimming pools, play areas, terraces, greenhouses, entrances to stadiums or other.
Since the construction of a permanent cover cannot be easily considered because of the above-mentioned reasons, removable protective structures have been proposed in which no guiding structure on the ground is used in order to simplify the implementation of such structures.
In a first known arrangement, telescopic components are erected with no rails on the ground, a guide wheel being provided on each side of every component. This arrangement does not allow for the lateral tensile stresses that are applied during use and does not permit the shelter to be suitably positioned in order to be fixed to the ground.
A second known arrangement proposed the use of rigid rails as a connection between the various components. However, this system proved to be of little practical use because of the systematic jamming of one or more components during the tensile forces and/or pressure applied to open up the shelter or during uncoordinated handling. In addition, in this second embodiment, anchoring to the ground, ensured by means of bolts, is time-consuming and tedious and the inadequate seal between components does not provide the shelter with the necessary corresponding quality.
Finally, due to the required presence of two rigid rails on the ground, the application of this type of structure to the installation of shelters of the movable veranda type cannot be easily envisaged.
There is disclosed in FR-A-2,568,288 and FR-A-2,575,955 a telescopic protective shelter of the general type already described but in which each shelter element is connected to an adjacent shelter element by a single guiding device which includes a roller.
However, in operation such an arrangement has a tendency to jam when the shelter is being extended or contracted telescopically, due to the inadequacy of the aforementioned guiding arrangement.
SUMMARY OF THE INVENTION
The object of this invention is to overcome the problems of shelter devices referred to above.
Another object of this invention is the implementation of a removable protective shelter for an activity or leisure area consisting of several telescopic shelter elements in which the overall and relative movement of all the shelter elements between them, with no lateral play, is obtained.
Another object of this invention is the implementation of a removable protective shelter for an activity or leisure area that allows rapid and effective fixing to the ground thereby ensuring great ease of implementation and use for the shelter thus obtained.
Another object of this invention is the implementation of a removable protective shelter for an activity or leisure area made up of several telescopic shelter elements in which a specific frame can be implemented, in accordance with the intended purpose of the shelter and/or its climatic environment.
Another object of this invention is the implementation of a removable protective shelter for an activity or leisure area thanks to which, with a minor adjustment to the design, in addition to a necessary adjustment to the shape, and application for the execution of movable verandas can easily be achieved.
The removable protective shelter for an activity or leisure area, which is the subject of this invention, consists of a substantially rigid frame and a substantially watertight cover over the frame.
It is significant in so far as the frame and cover form a plurality of telescopic shelter elements, that shelter element is assembled on watertight slides with regard to another adjacent shelter element by means of at least on
