Enclosure, especially SPA enclosure

Subject of the invention is enclosure, especially SPA enclosure, which has the shape of, beneficially rotationally sliding, semispherical cap, beneficially containing sliding door. The invention is intended especially for small pools with hy- dromassage, used in different atmospheric conditions.

There are known enclosures, produced from profiles, beneficially aluminum profiles, which create the frame of enclosure, inside of which there are transparent or semitransparent plates, manufactured from plastics, beneficially from polycarbonate.

There is known, from patent description USA No 4 246 663, enclosure of swimming pool, containing rotationally sliding semispherical cap, whereas the cap is divided in two parts, and the smaller one, with smaller diameter is rotationally sliding into interior of bigger one. In the upper part of the enclosure, there are two coaxial, rotary bushes, located one above the other, where upper ends of rack tubes of every cap, are fixed. In the lower part, there is a system of rollers and holders, fixing the enclosure to the ground.

There is known, from Canadian patent description No CA 2154374, the enclosure for SPA or similar swimming pools, where the cover located on the extension arm, is containing the frame, ends of which have rollers moving on tracks fastened on the edge of basin.

The enclosure, especially for SPA, according to the inventtion, having the shape of rotationally sliding, partially divided semispherical cap, characterized in that it includes some spherical elements, each of them created by frame, having inside beneficially transparent plates, whereas the lower part of spherical segments is located on the track, having shape of circle, placed on the ground. The upper parts of segments are coupled to the edge of cover, which has the shape of beneficially transparent cap, whereas between the edge of cover and the lower track, there is slide door, consisting of at least one spherical segment. The running rail is made from the profile, the flat base of which is on one side finished with vertical wall, and on the other, vertical wall goes into horizontal blocking segment, and at the i

same time, in the center of base, the running rail is located, having the shape of hollow cylinder. The lower part of segment frame is created by the lower running profile, whereas the upper part is created by the lower edge profile, while the side walls of frame are made of base profile. Plates in segment are connected with centrally located intermediary base profile, while inside of lower running profile are at least two guiding rollers. The lower running profile has a bay for a plate, having shape of partly upwards open channel, below which the rectangular channel is located, and below that, the open channel, oblique to channel axis, the upper wall of which is at the same moment the lower wall of open channel, containing two longitudinal tongues. There is a door running profile fixed to side wall of running profile, having the shape of fence, finished with ball-shaped edge. The lower edge profile has a bay for plate, having shape of partly open down channel, above which the rectangular channel is located, and further above partly open polygonal channel, oblique to channel axis, whereas above this channel there is connecting shelf, containing the trapezoidal, closed channel. Base profile is containing the bay for a plate, having the shape of channel, partly open at bottom, beside which the rectangular channel is located, while on the protraction of channel wall, the shelf is located, with decreasing section, comprising the bay for sealing. Intermediary base profile is containing two symmetrically located bays, having the shape of partly down open channel, whereas in the central part, between two closed channels, the channel with rounded edges is located.

Edge of surface part is created by upper edge profile, containing oblique, partly open, rectangular channel, for the upper transparent plate, connected by side wall to partly open downwards channel, whereas the rectangular channel is connected with lower wall to partly open channel, resembling the digit 1, which is connected by lower wall with open, trapezoidal channel. The upper, transparent plate is beneficially divided into four parts, connected by intermediary profile.

The lower base of door leaf is created by running profile, to which at least one symmetrical guiding roller is fixed, at the same time, from the other side, the guiding roller is located on the running track, beneficially by arm. The upper door edge is finished with the upper running profile, beneficially containing the bay, having the shape of partly up-side open channel, below which there is a rectangular

channel, at the same time inside the profile there are located at least two oblique guiding rollers, whereas the door side edges are created by base profile and plates of door leaf are beneficially connected to centrally located, intermediary base profile.

In the other alternative of invention, the enclosure of SPA is characterized in that it contains several semispherical segments, each of them created by frame, where inside are beneficially located transparent plates, at the same time the lower part of segments is located on the oval running track, placed on the ground. On the top, segments are separably connected to the edge of upper part, being beneficially transparent bowl with the oval base, comprising plates, beneficially of polycarbonate, at the same time on at least one arc part, between the edge of upper part and lower running track there are sliding door, consisting of at least one leaf, having spherical shape. The enclosure is equipped with the door, at least on one side. Upper part is created, beneficially by two semispherical bowls, beneficially transparent, with frame between them, equipped with plates and sliding part, located on tracks by guiding rollers.

The guiding track of the edge of surface is made of the profile, whose flat base is finished one side with the edge, and on the other the vertical wall is finished with horizontal, blocking segment. There is running track, located on the base, for guiding roller, having the shape of hollow cylinder, and located inside the profile. The guiding track is fixed to side wall of upper profile, connected with lower profile, while in the middle part of top cover, a track is fixed to angle surface of upper profile wall. The lower part of segments frame is created by lower running profile, whereas upper part is created by lower profile of surface edge, while frame side walls are made of base profile. Plates in segments are connected by centrally located base profile, while inside of lower running profile at least two guiding rollers are located. There is a door running profile, fixed to side wall of running profile, having the shape of strip finished with rounded edge.

The enclosure, according to invention, allows for protection of the swimming pool against, for example weather conditions, and thanks to rotary, sliding construction allows for any setting of enclosure, around the rotation axis. Whereas in the second invention alternative, construction of sliding front doors, located on

arched part and side doors, as well as upper part of enclosure, allows for proper ventilation of protected space above the swimming pool. Design of enclosure allows for quick and easy assembly of particular segments and door leafs. Application of aluminum profiles and polycarbonate plates, assures high stability and durability of construction, at the comparatively low weight of enclosure.
