1. Field of the Invention
The present invention relates to grating for the overflow edge of swimming pools.
2. Description of Related Art
Overflow grating is used to cover pool drainage channels that extend around the perimeter of the pool. The grating generally has slats or openings to allow water to flow through the grating and into the drainage channels. Overflow grating is typically formed of T-shaped or I-shaped plastic bars having a connecting element made from plastic to connect each plastic bar together. The overflow grating is generally subjected to harsh conditions, such as pool cleaning chemicals and sunlight. After a period of use, the plastic of the overflow grating may become brittle and eventually break creating a sharp edge that is dangerous to the swimming pool users. Furthermore, the color of the plastic may become faded, which reduces the aesthetic value of the overflow grating.
In one embodiment of the present invention, a grating for an overflow drainage channel of a swimming pool is provided. The grating includes a plurality of bars having a passage extending in a transverse direction therethrough, a plurality of spacer elements having an aperture substantially aligned with the passage and positioned between the plurality of bars, and a connecting member extending through the passage of the plurality of bars and the aperture of the plurality of spacer elements to secure the plurality of bars and the plurality of spacer elements together.
In another aspect, a method of forming a grating for an overflow drainage channel of a swimming pool is provided. The method may comprise the step of providing a plurality of bars having a passage extending in a transverse direction therethrough, a plurality of spacer elements having an aperture substantially aligned with the passage and positioned between the plurality of bars, and a connecting member. The method may further include the step of threading the connecting member through the passage of the plurality of bars and the aperture of the plurality of spacer elements to secure the plurality of bars and the plurality of spacer elements together.
For purposes of the description hereinafter, spatial orientation terms, if used, shall relate to the referenced embodiment as it is oriented in the accompanying drawing figures or otherwise described in the following detailed description. However, it is to be understood that the embodiments described hereinafter may assume many alternative variations and embodiments. It is also to be understood that the specific grating illustrated in the accompanying drawing figures and described herein are simply exemplary and should not be considered as limiting.
In one embodiment, shown in
The connecting member 30 may be a rope, sling, elastic material, or any other suitable material for securing the bars 10 and spacer elements. The bars 10 may be made from stainless steel, unplasticized polyvinyl chloride (UPVC), wood, or any other suitable material that is resistant to UV-sunlight and chemical erosion. Further, the materials for the bars 10 may be waste or residue materials from other processes that are recycled and used to form the bars 10. The use of waste or residue materials prevents the formation of sharp angles or edges if the bars 10 become broken after extended use. The spacer elements 20 may be made from aluminum, stainless steel, polyethylene (PE), or any other suitable material that is corrosion-resistant.
In certain embodiments, a bar 50 positioned at an end of a grating 60 includes a passage 52 as discussed hereinabove as well as a securing hole 54 extending through at least a portion of the bar 50. The securing hole 54 is dimensioned to receive an end of the connecting member 30 and fixedly attaches the end of the connecting member 30 to the bar 50. Further, the bar 50 may include a trench 56 formed between the passage 52 and the securing hole 54 for receiving at least a portion of the connecting member 30. In particular, as shown more clearly in
In another embodiment, shown in
In yet a further embodiment, a plurality of gratings 1 is provided for an overflow drainage channel of a swimming pool. An attaching member (not shown) may be provided between each of the gratings 1 to prevent the gratings from moving relative to one another. The attaching member (not shown) may be made of stainless steel, aluminum, PE, or any other suitable material which can endure chemical erosion and UV-sunlight.
Although the grating 1 was discussed hereinabove in connection with swimming pool drainage channels, the grating may also be utilized for other purposes, such as for use as a walkway on a grass yard. Furthermore, the grating 1 as shown in
While certain embodiments of the grating were described in the foregoing detailed description, those skilled in the art may make modifications and alterations to these embodiments without departing from the scope and spirit of the invention. Accordingly, the foregoing description is intended to be illustrative rather than restrictive.
