Set of parts for building the upper edge and channel in overflow swimming pools

Abstract

A set of parts having a “U” shaped channel (11) and a side prolongation (12) are used to form the upper edge and channel in an overflow type swimming pool. The set of parts can include straight parts (1a), corner parts (1b), drainage parts (1c), fitted steps, lane divider anchors, and curved edges. The upper surface of the prolongation slants toward the edge of the swimming pool at an angle of approximately 1 to 15 degrees and forms a base to place tiles to finish the appearance of the swimming pool. The parts can be constructed of ceramic, cement, stoneware, baked clay or other polymer.

Description

FIELD OF THE INVENTION

This invention refers to a set of parts for building the upper edge and channel in overflow swimming pools, in one single operation.

BACKGROUND

Around overflow swimming pools a channel is built at water level or below. There are different types of overflow pools, the main ones are known under the trade names of the Finnish System and the Zurich System, the main difference being the difference in levels between the water and the channel.

To build this edging and channel in overflow pools, a system of two successive casings is often required, which owing to its particular design, is extremely complicated, because any minor deviations that usually occur to a greater or lesser extent, make it impossible to then place the ceramic parts properly or for the pool to overflow correctly.

There is a variant to the Zurich system on the market, trading under the name of Wiesbaden, which attempts to solve these problems with a ceramic part. This part is used as edging, channel and outer surface at the same time, but because it is made in ceramic, it is very expensive. Also, it must be of a very small size and it can only be applied in cases where there is limited space. These parts cannot be used for the Finnish system as they cannot provide the so-called “beach,” which is the submerged part of the swimming pool edge between the channel and the inside vertical wall.

Correcting these deviations of the edging/channel later on means significant additional labor costs, as part of the cement has to be chipped, or the inadmissible gaps have to be filled, or what is worse, the different angles needed on the edge near the channel have to be adjusted. This is the situation in the most popular of all the systems: the Finnish system.

SUMMARY OF THE INVENTION

To solve these problems, a set of parts has been designed, that enables building the edging and the channel of the overflow swimming pool in one single operation that is both simple and safe. This set of parts includes straight parts, corner parts, drainage parts, parts for the location of fitted steps, parts to anchor lane dividers, and parts for curved edges. They all have a “U” shaped section that forms the channel itself, the fitting for the grille, and a side prolongation that forms the edge of the pool. The upper surface of this part is used as a base to place the ceramic or stoneware parts that finish the edge of the swimming pool at a convenient level.

The parts that comprise the invention form the edge of the pool and the channel at the same time. These component parts can be manufactured in ceramic, cement, stoneware, baked clay, plastic or another material similar to any of the above.

The side prolongation that forms the edge of the pool and is used as a base to place the tiles that finish the edge of the pool, has been designed so that it can have a hollow configuration, in order for the base to be coplanar with the “U” configuration, so that parts can be placed on a flat surface, as if they were flat tiles, and the upper surface is horizontal, or slanted in the opposite direction of the “U” configuration from which it projects.

DETAILED DESCRIPTION OF THE INVENTION

Straight parts (1a) have a “U” configuration (11) in section and a hollow side prolongation (12).

The upper edge of the swimming pool is built by placing several straight parts (1a) adjacently. The “U” configuration (11) forms the channel, while the side prolongation (12) forms the edge of the swimming pool. The upper surface (13) of the side prolongation (12) can slant downwards and be more or less terraced (FIGS. 5a, 5b) depending on the overall angle of 7 or 8 degrees, or it can be horizontal (FIG. 6), forming in all cases a suitable surface to place tiles (2) that finish the edge of the swimming pool.

The corner parts (1b) with an angular configuration have the same section as the straight part (1a). Whether they have a 90-degree angle or another value, the corner parts are shaped by what would be simply joining two straight parts (1a) depending on the required angle. The preferred embodiment of a corner part, shown in FIG. 9 as a top view, is the result of angle cutting two straight parts at 20 and joining them.

At the bottom of the “U” configuration (11), the drainage parts (1c) have a hole (14) to connect a drainage pipe (3) for the water collected in the channel.

The parts for fitted steps have the same normal features as the straight parts, with the difference being that the side prolongation (12) is shorter, as indicated in FIG. 7.

The parts used to anchor lane dividers differ from the straight parts as the side prolongation (12) is solid with a hole (16) part way through the prolongation (12) to provide anchorage.

In order to prevent possible cracks in the join between adjacent parts (1a, 1b, 1c) that could cause water from entering inside the side prolongation (12) with the resulting problems such as water freezing that could break the part, the inside hollow of the prolongation (12) is typically filled with a low-density plastic material (15), such as expanded polyurethane foam.

FIG. 4 shows one of the straight parts (1a) forming a length of the channel and the edge of the overflow swimming pool, the tiles (2) that finish the edge of the pool, the outer tiles (5), the grille (4) that covers the channel, and the drainage pipe (3).

The materials, shape, arrangement and layout of elements may vary as long as this does not alter the basic features of the invention, the claims of which are made below.
