Patent ID: 8661575

Claim:
A system for a swimming pool opening, the system comprising: a plurality of roof components, including a first roof component and a second roof component, each roof component including a cover, and a rigid frame including two arches, a first end crosspiece delimiting a first longitudinal edge-part configured to rest on a first longitudinal edge of the pool, and a second end crosspiece delimiting a second longitudinal edge-part configured to rest on a second longitudinal edge of the pool, the second longitudinal edge-part being parallel to the first longitudinal edge-part; a storage area located at an end of the pool the storage area being sufficient to accommodate a footprint of a roof component, allowing the roof components to be stored in a stacked way, all of the storage area being horizontally displaced from the pool opening, thereby exposing the swimming pool opening; a wheel configured to mobilize the roof components, allowing the roof components to be displaced horizontally in a linear movement direction along the pool towards and/or away from the storage area; a lifter in the storage area, the lifter being configured to engage the roof components to vertically displace the roof components, and place one roof component onto another roof component in a stacked position; and a convex member attached to a first roof component in the plurality of roof components and a concave member attached to a second roof component in the plurality of roof components, configured such that a vertical displacement of the concave member relative to the convex member acts to engage the first roof component with the second roof component, whereby the roof components can be juxtaposed such that the first longitudinal edge-part of the first roof component is on a first line parallel to the linear movement direction, the first longitudinal edge-part of the second roof component is on the first line parallel to the linear movement direction, the second longitudinal edge-part of the first roof component is on a second line parallel to the linear movement direction, and the second longitudinal edge-part of the second roof component is on the second line parallel to the linear movement direction, thereby covering the swimming pool opening.
