BACKGROUND OF THE INVENTION
The present invention relates generally to collapsible domes and, more particularly, to a collapsible arch supported lightweight tension dome which is especially suitable for use on round shaped swimming pools.
The art abounds with many different types of portable and collapsible shelters used for many different purposes. A typical example of such shelters is disclosed in U.S. Pat. No. 3,905,908 which discloses a collapsible shelter whose height depends on the area covered and is therefore not suitable to cover larger round shaped pools.
BRIEF SUMMARY OF THE INVENTION
The prior art discussed above may be readily suitable for shelter from wind and rain, for use on the beach, camping facilities or terraces and the like. However, these structures, especially those above ground level, which when folded in a collapsed position should be placed around one side of a pool without having its parts in it, are not suitable for covering large, round shaped swimming pools. In order to be suitable, the prior art structures would have to have arches of the same radius as the pool, thereby attaining a height, which for optical and wind load reasons would be too high for larger round shaped pools. Although the height of prior art structures that do not have an arch in a vertical position can be lowered by increasing the roof section between the two most vertical inclined arches, this limited method is suitable only for smaller round shaped pools not exceeding cca. 12 feet due to the increasing roof load as well as for optical reasons.
The principal idea of this invention is to provide a means by which a lightweight, arch-supported, collapsible dome, designed for covering round shaped pools, can be shifted on one side or on both sides along the round shaped pool's edge before being collapsed, thereby making possible the use of the lower arches, resulting in a lower structure.
It is also an object of the present invention to provide a means for quick and easy pivotable attachment and detachment of the two-arch collapsible dome to the pool's edge.
The foregoing and other objects and advantages will appear from the description as follows.
In the description, reference is made to the accompanying drawing, which forms a part hereof and which is shown by way of illustration a preferred embodiment in which the invention may be practiced. The preferred embodiment will be described in sufficient detail to enable those skilled in the art to practice the invention and is to be understood that other embodiments may be utilized and that some changes may be made without departing from the spirit and scope of the present invention. The following detailed description is therefore, not to be taken in a limiting sense but the scope of invention is best defined by the appended claims.
