Pool grating having curves therein
A structure for installing grate bars in a swimming pool having straight and curved section. The pool has a top gutter formed in concrete. The grate bars follow the concept of being parallel to a pool wall. A multiple of spaced apart elements support elements are placed over the gutter at predetermined intervals and fastened to the top of the concrete. A pre-assembled grid of longitudinal grate bars is placed over the support elements and fastened thereto. The pre-assembled grate bars are held together by lateral stays. In the curved section, individual grate bars placed onto the support elements one by one and are bent into the respective curves of the gutter. the individual grate bars are received between the spaces of the knobs on the support elements and snap fitted therein.
The invention pertains to pool constructions, particularly, it is directed to the overflow gutter concept. The overflow gutter concept is increasingly being used in the United Sates an other countries. This concept is not only used in large swim competition pools but also in leisure and residential pools. The perimeter overflow system is often called deck level, overflow or wet deck. This type of construction involves a gutter which is placed around the whole perimeter of the pool and placed at the deck level of the pool so that water can flow into the gutter and a grating covers the opening of the gutter which is placed at deck level. The grating has to be strong enough to accommodate foot traffic near the edge of the pool. Known gratings have connecting stays that run perpendicular to a pool wall. They are extruded, are somewhat flexible and can handle a radius. Gratings constructed with stays or grate bars that run parallel to the edge of the pool have a tendency to hinder the flow over the grate because the parallel stays present an obstacle to water flow which is highly desirable in pool constructions because this way the concrete deck remains mostly dry and prevents feet from slipping thereon.
Such pool deck and grate construction has been disclosed by the applicant in U.S. Pat. No. 6,968,665 and has been found to be most successful, however, the construction and installation has proven to be somewhat time consuming and cumbersome.
BRIEF DESCRIPTION OF THE INVENTIONThe present invention greatly simplifies the construction of a swimming pool having curves and having grate bars that are parallel to the walls of the pool. This is accomplished by pre-manufacturing grate bar grids that are installed over the gutter and in straight sections of the pool. The grids are supported by support elements that straddle the gutter. The support elements are reinforced by a grid array below the top. The tops of the support elements have U-shaped receptacles that will receive straight grate bars. The support elements are spaced apart at predetermined intervals in the curves of the pool gutter. Straight grate bars are secured in the U-shaped receptacles and can be bent into shape to follow the curvature of the gutter.
The curved section is shown at 30 and a straight section is shown at 31.
The construction of the straight section will be explained with reference to
Claims
1. A structure for installing grate bars in a swimming pool, said swimming pool having the concept of grate bars running parallel to a wall of the pool, said pool having a gutter at a top thereof, said gutter having straight and curved sections, said gutter further having support elements on top of the concrete from which said gutter is formed, said support elements having ends and are spanning said gutter and are fastened to said concrete by lag screws at the ends of said support elements, said support elements are spaced along said straight and said curved sections at predetermined intervals, said straight section receiving a grid of pre-assembled grate bars on top of said support elements, said curved sections having individually bent grate bars fastened to a top of said support elements.
2. The structure of claim 1, wherein said grate bars have a hollow nose assembly installed between said grate bars and an edge of the pool.
3. The structure of claim 2, wherein said hollow assembly has a longitudinal depression placed downwardly from a top of said hollow assembly to act as finger grips for a user in said pool.
4. The structure of claim 1, wherein said grate bars have a U-shaped cross section and having a friction inducing design on top of the grate bars.
5. The structure of claim 1 including a male clip at one end of said grate bars and a female receptacle at another end of said grate bars, whereby, when said male clip of one end of one grate bar is snapped into said female receptacle at one end of another grate bar, said grate bars will be rigidly connected to each other.
6. The structure of claim 1, wherein said support element has a reinforcing array below a top of said element, said array extending downwardly into the gutter.
7. The structure of claim 1, wherein said support element has spaced apart knobs on top of said element and each of said knobs has lateral hooks thereon.
8. The structure of claim 7, wherein each of said U-shaped grate bars has lateral barbs thereon, and when said grate bars are introduced between said knobs, the barbs on said U-shaped grate bars will snap under said hooks of said knobs.
9. The structure of claim 1, wherein said pre-assembled grate consists of a grid having a multiple of spaced apart lateral stays, the lateral stays are molded simultaneously with longitudinal grate bars which are spaced apart, the ends of said spaced apart longitudinal grate bars have at one end thereof male clips thereon and have female receptacles on the other end so that a multiple of longitudinal grate bars can be snapped together.
