A collapsible dome includes two or more arches of larger radius than half of the diameter of the pool which are therefore lower and provide a consequently lower structure, preferably of arcuated shape. Arches are pivotably attached on one end to the first support base, mounted to the pool's edge, and on the other to the second support base. Second support base is slidably hung upon a support guide bar which is mounted on the pool's edge with one end opposite the first support base and a membrane cover attached to each arch and tensioned after set up to the pool's edge. While the membrane is not fastened to the pool's edge, one side of the collapsible dome can easily be shifted along the support guide bar. Before collapsing the dome, the second support base should be shifted along the support guide bar in the appropriate direction to decrease the circumference between the first and second support bases. The arches, having a larger radius than the pool, would otherwise collapse into the pool instead of onto the pool's edge. When the dome is used on pools with shape different than round like oval or rectangular, shifting of both support bases along the pool's edge before collapsing of the dome is required to assure collapsing of the dome on or behind the pool's edge. Domes having only two arches are quickly and easily attached to the pool's edge by pivotable attaching components, which include two cups into which the ends of the arches are put by means of slip joint assemblies, bound by a cord that permits pivotal movement to the base support.

This is a continuation-in-part, of my application application Ser. No. 09/266,670, filed on Mar. 9, 1999 anbandoned.
A spa cover lift and cover construction that easily accommodates use with odd sizes and shapes of spas. The construction uses a column which is positioned at a single location about the periphery of the spa. A foot piece can be included at the bottom of the column which slips under the spa to use the weight of the spa and water to help hold the cover lift and cover securely. The column is preferably adjustable in height. It has pivot arms which extend in recesses formed in the underside of one half of the cover. The pivot arms extend from the column out to the side edges and are looped to form a handle and return that further supports the cover on the lift. The pivot arms may have tail ends that engage a bumper when the cover lift is retracted. Control arms may be pivotally connected between the column and pivot arms to resist erratic movements.
A pool cover assembly for covering for covering an above ground swimming pool during periods of non-seasonal use includes a plurality of pool cover brackets arranged about and on the railing of the swimming pool with each pool cover bracket including a hook for engaging the inner lip of the railing and a socket member which projects inwardly, and at an acute angle, toward the swimming pool in order to receive the ends of pole cover supporting beams whereupon each supporting beam will extend across and above the swimming pool for securement to oppositely arranged pairs of brackets thereby forming a cambered framework that supports a pool cover above and around the swimming pool. Each pool cover bracket also includes a ring secured adjacent the hook, and to which the end of a thrust reduction member, such as an elongate metal rod, is attached so that each thrust reduction member can be attached to oppositely arranged pairs of pool cover brackets in order to alleviate the lateral and horizontally directed force of the ends of the supporting beams, and the weight of any debris accumulated on the pool cover, against the sidewall of the swimming pool.
A water transportation system and method are described, generally related to water amusement attractions and rides. Further, the disclosure generally relates to water-powered rides and to a system and method in which participants may be actively involved in a water attraction. This transportation system comprises at least two water stations and at least one water channel connecting the at least two water stations for the purpose of conveying participants between the at least two water stations. In addition, the water transportation system may include conveyor belt systems and water locks configured to convey participants from a first source of water to a second source of water which may or may not be at a different elevation.
An amusement ride system and method are described. In some embodiments, an amusement ride system may be generally related to water amusement attractions and rides. Further, the disclosure generally relates to water-powered rides and to a system and method in which participants may be more involved in a water attraction. An amusement ride system may include an elevation system for conveying a participant from a first source of water to a second source of water. An elevation system may assist in adjusting and/or controlling a participant flow rate through at least a portion of a water amusement park. An elevation system may include two or more conveyor belt systems. An elevation system for adjusting a participant flow rate may include one or more floating queue lines. An elevation system may include a control system. A control system may be automated, semi-automated, or manual.
