Description

FIELD OF THE INVENTION

The present invention concerns a plasticized material and methods for using the material in the construction or repair of artificial pools. More particularly, some embodiments of the present invention concern a covering made from pliable plasticized material which can be used to cover and conceal an expansion joint of a swimming pool. A covering may have one or more perforations for separating the covering into multiple partitions.

BACKGROUND OF THE INVENTION

When pools are constructed or repaired, much time and effort is spent ensuring that the pool is properly sealed so that water does not penetrate the ground surrounding the pool. One area which is particularly vulnerable to water intrusion is between the pool tile and the deck, or coping, of a swimming pool. To prevent this, the area may be filled with caulking or fitted with flexible plastic—creating what is known as an expansion joint. In some cases, the joint may be covered by thin, but rigid, pieces of plastic, which may be provided as a decorative feature and/or to protect the seal from water and sunlight. Over time, however, these pieces, or coverings, may be degraded and damaged by moisture and ultraviolet light, eventually requiring replacement. However, these conventional coverings are typically difficult to manipulate in order to achieve one's desired specifications. For example, for pools having curved perimeters, one may have to use several coverings along the extent of a curved wall, due to the inflexibility of the conventional material. As a result, repairing seal coverings in pools by means of conventional coverings are often time-consuming and tedious.

There therefore exists a need for a material which provides allows for quick and easy replacement of joint coverings. Furthermore, there exists a need for a material which is flexible and easily manipulated in order to accommodate pools of various shapes and sizes.

BRIEF SUMMARY OF THE INVENTION

The present invention generally concerns a covering which may be made from flexible, plasticized material and which can be used to cover gaps and joints within, or between, a wall and coping of an artificial pool. In some embodiments, the covering can be used to conceal a joint in a newly constructed pool, repair an existing joint covering, or to conceal an existing joint. In preferred embodiments, the covering may be formed as a thin, elongated, and pliable strip which can be used to conceal an expansion joint located between a row of pool tiles and a deck, or coping, of a swimming pool. It is to be appreciated, however, that applications of the present invention may not be limited to swimming pools. For example, the covering may also be used in the construction or repair of spas and artificial ponds, or the like.

According to some embodiments of the present invention, a covering may be constructed, in whole or in part, from flexible material, such as, but not limited to, plastic, vinyl, or polymers thereof (e.g., polyvinyl chloride). The covering may also be treated with one or more ultraviolet (“UV”) stabilizers to prevent UV damage. Provided on at least one side of the covering, or a portion thereof, may be a scored, or textured, surface (i.e., a surface with plurality of small protrusions, bumps, or indentations, or the like) for bonding with an adhesive. In some embodiments, a large protrusion or bump may be formed on a side of the covering, which can be inserted into a joint.

In some embodiments, a covering may have one or more perforations for separating the covering into two or more partitions, or segments. According to some aspects, a perforation may be formed into a covering such that the covering may be separated, or torn, by hand along the perforation. In some embodiments, one or more perforations may be formed in a widthwise direction of a covering in order to separate the covering into relatively shorter partitions (i.e., shorter than the unseparated covering). One or more perforations may also be formed in a lengthwise direction of a covering in order to separate the covering into relatively narrower partitions.

In some embodiments of the present invention, one or more perforations of a covering may be formed in a substantially straight line, which may be parallel, or perpendicular, to an edge of a covering. For example, a perforation may be formed along a centerline of a covering such that, when the covering is separated at the perforation, two equally sized, uniform partitions may be formed. In other embodiments, a straight-line perforation may be oriented in a diagonal direction, relative to an edge of a covering, such that the partitions of the covering may have graduated widths.

In some embodiments, a covering may have one or more perforations which may be irregular (i.e., not straight). For example, a perforation may be curved and/or may have a repeating pattern. In some embodiments, a covering may be colored and may have decorative features or designs. In certain embodiments, one or more colors may be used to distinguish between different types of coverings. For example, different colors may be used to distinguish between coverings of varying sizes or shapes.

In accordance with some embodiments of the present invention, one or more coverings, as described herein, may be used in constructing or repairing artificial pools. A covering may be adapted to be engaged with another covering, either along a lateral edge or along a perforation, allowing two or more coverings to be adjoined. In one implementation, a covering (or plurality of coverings) may be used in a swimming pool to cover and conceal a joint which may exist between the top edge of a row of pool tiles and the bottom edge, or surface, of the pool deck, or coping. In one exemplary implementation, a method of using a covering to conceal an expansion joint of an artificial pool may include the steps of: i) separating a covering along a perforation to form two partitions; ii) preparing the expansion joint and one of the partitions for adhesion; and iii) placing a portion of the prepared partition over the expansion joint such that one side of the prepared partition is bonded with the expansion joint. In some implementations, concealing an expansion joint may further include a step of iv) inserting a portion of a protrusion on a side of the covering into the expansion joint. In some implementations, preparing an expansion joint and a partition for adhesion may include filling the expansion joint with an adhesive and/or applying an adhesive to a scored surface of a partition. In some cases, an existing seal within an expansion joint may be removed before applying an adhesive.

In some circumstances, two or more coverings may be used to cover a joint or gap. For example, if a gap or joint is wider than a covering, a user may need to apply a second covering directly above or below a first covering to ensure complete coverage. In other cases, a full covering may not be needed to cover the entire area. In such cases, a user may cut, or tear, a covering along a perforation to obtain a narrower partition. In some circumstances, a gap or joint may not be uniform across a given area. For example, the size of a gap or joint may increase or decrease in a lateral direction, requiring coverings of varying sizes. In such cases, a user may utilize, for example, a covering having a graduated width (i.e., diagonally formed perforation) to account for gaps or cracks which are non-uniform.

In accordance with some embodiments of the present invention, a covering for an expansion joint of an artificial pool may comprise: a) an ultraviolet stabilizer; b) at least one vertical perforation and at least one horizontal perforation for separating the covering into at least two partitions; and c) at least one side having a scored surface for bonding with an adhesive; wherein the covering may be formed as an elongated strip and may be constructed from a plastic polymer. In one further embodiment, a perforation may be substantially straight. In another further embodiment, a perforation may be curved. In one further embodiment, a partition may be uniformly shaped. In another further embodiment, a partition may be irregularly shaped. In one further embodiment, the ultraviolet stabilizer may comprise a hindered amine light stabilizer. In one further embodiment, a side of the covering further may comprise a protrusion for insertion into the expansion joint.

In accordance with some implementations of the present invention, a method for concealing an expansion joint of an artificial pool may comprise using a first covering, wherein the first covering may be formed as an elongated strip and may comprise: a) a first side, b) a second side, c) an ultraviolet stabilizer, d) a perforation for forming two partitions, and e) a scored surface on the second side; and wherein the expansion joint may be between a row of tiles and a coping of an artificial pool, the method comprising the steps of: i) separating the first covering along the perforation to form a first partition and a second partition, each having a first side and a second side; ii) preparing the expansion joint and the first partition for adhesion; and iii) placing a portion of the first partition over the expansion joint, wherein the second side of the first partition may be bonded with the expansion joint. In one further implementation, the step of preparing the expansion joint and the first partition for adhesion may comprise filling the expansion joint with an adhesive. In another further implementation, the step of preparing the expansion joint and the first partition for adhesion may comprise applying an adhesive to the scored surface. In one further implementation, the step of preparing the expansion joint and the first partition for adhesion may comprise removing an existing seal within the expansion joint. In one further implementation, the second side of the first partition of the first covering may comprise a protrusion. In an even further implementation, the step of placing a portion of the first partition of the first covering over the expansion joint further may comprise inserting a portion of the protrusion into the expansion joint. In one further implementation, the method of concealing the expansion joint of an artificial pool may further comprise using a second covering, wherein the second covering may be formed as an elongated strip and may comprise: a) a first side; b) a second side; c) an ultraviolet stabilizer; d) a perforation for forming two partitions; and e) a scored surface on the second side, wherein the method further comprises the steps of: iv) separating the second covering along the perforation to form a first partition and a second partition, each having a first side and a second side; v) preparing the expansion joint and the first partition of the second covering for adhesion; and vi) placing a portion of the first partition of the second covering over the expansion joint, wherein the second side of the first partition of the second covering may be bonded with the expansion joint. In one further implementation, the first partition of the second covering may be abuttingly engaged with the first partition of the first covering. In an even further implementation, the method may further comprise the step of: vii) inserting a protruding edge of the first partition of the second covering into a slotted edge of the first partition of the first covering. In one further implementation, the method may further comprise the steps of: vii) preparing the expansion joint and the second partition of the second covering for adhesion; and viii) placing a portion of the second partition of the second covering over the expansion joint, wherein the second side of the second partition of the second covering may be bonded with the expansion joint and wherein the second partition of the second covering may be abuttingly engaged with the first partition of the second covering. In an even further implementation of the method, the first partition of the second covering may be abuttingly engaged with the first partition of the first covering.

In accordance with some embodiments of the present invention, a system for concealing an expansion joint of an artificial pool may comprise at least two coverings and an expansion joint, wherein the coverings comprise: a) at least one perforation for forming at least two partitions; and b) at least one side adapted to bond with an adhesive within the expansion joint; wherein the at least two coverings may be formed as elongated strips, wherein the at least two coverings may be constructed from a plastic polymer, and wherein the at least one perforation of a first one of the at least two coverings may be adapted to abuttingly engage the at least one perforation of a second one of the at least two coverings.

DETAILED DESCRIPTION OF THE INVENTION

The invention, in its various aspects, will be explained in greater detail below. While the invention will be described in conjunction with several exemplary embodiments, the exemplary embodiments themselves do not limit the scope of the invention. Similarly, the exemplary illustrations in the accompanying drawings, where like elements have like numerals, do not limit the scope of the exemplary embodiments and/or invention, including any length, angles, or other measurements provided. Rather the invention, as defined by the claims, may cover alternatives, modifications, and/or equivalents of the exemplary embodiments.

The present invention generally concerns a covering, preferably made from plasticized material, which can be used to cover, conceal, and/or protect gaps and joints in artificial pools. In preferred embodiments, a covering can be used to conceal a joint between a wall and a deck, or coping, of a swimming pool. For example, a covering may be used to seal an expansion joint between the uppermost edge of a row of pool tiles and the bottom edge, or surface, of the pool coping. It is to be appreciated, however, that applications of the present invention may not be limited to swimming pools. For example, and without limitation, a covering may also be used in the construction or repair of spas or artificial ponds, and the like.

According to some embodiments of the present invention, a covering may be formed as an elongated strip which may be substantially thin (i.e., less than 1 centimeter in thickness), pliable, and durable. In some embodiments, a covering may have a width of between about 0.5 inches and 2 inches, but preferably about 1.25 inches. It is to be appreciated, however, that a covering may be wider or narrower depending on the size of an area to be covered. A covering may be adapted to be engaged or adjoined with another covering, either along a lateral edge or along a perforation. In some embodiments, a covering may be adapted to abuttingly engage another covering.

A covering may be constructed, in whole or in part, from flexible and water-resistant material, such as a plastic or vinyl polymer, but preferably from polyvinyl chloride (“PVC”). In some embodiments, a covering may be coated or treated with a protectant to increase moisture resistance. In preferred embodiments, a covering may also be treated with an ultraviolet (“UV”) stabilizer, absorber, or blocker, or combinations thereof, to prevent degradation, corrosion, and/or damage caused by UV light. For example, a covering may be treated with a hindered amine light stabilizer (“HALS”).

In some embodiments of the present invention, a covering may have one or more perforations for separating the covering into two or more partitions (or segments, sections, pieces, portions, etc.). In some embodiments, the width of a partition may be between about 0.1 inches to about 1 inch, but preferably about ⅝ of an inch. In preferred embodiments, a perforation may be formed into a covering such that the covering may be separable, or torn, by hand along the perforation. In some embodiments, a perforation may be formed in a widthwise or lengthwise direction of a covering, allowing the covering to be quickly and easily sized according to one's desired specifications. For example, as illustrated in FIGS. 1A and 1B, a covering 10 may have a vertical perforation 11 and a horizontal perforation 12, formed in a widthwise and lengthwise direction, respectively, of covering 10—allowing covering 10 to be separated into two or more partitions comprising sections 10A, 10B, 10C, and/or 10D. It is to be appreciated that a covering may be separated into a partition which may comprise one or multiple sections of a covering. For example, covering 10 may be separated to form a partition comprising: i) only one of sections 10A, 10B, 10C, or 10D; ii) combinations of two of sections 10A, 10B, 10C, or 10D; or iii) combinations of three of sections 10A, 10B, 10C, or 10D.

In some embodiments, a covering may have protrusions, bumps, indentations, and/or ridges, or the like, which may provide a textured, or scored, surface for bonding with one-part or two-part adhesives, such as, but not limited to, silicone-based or epoxy-based adhesives. One or more protrusions may form linear, cross-hatched, or wavelike patterns, or any other patterns or combinations thereof, which may extend over a portion of a side of a covering. For example, as illustrated in FIG. 1B, covering 10 may include one or more protrusions 13 on a back side 19 for providing a scored surface for bonding with an adhesive. In certain embodiments, a covering may have one or more elongated protrusions which may extend in a lateral direction from a side of the covering, which can be positioned in a joint or gap. For example, as illustrated in FIG. 2, a large wedge-shaped protrusion 130 may be provided on a back side 190 of a covering 100, which may allow for better adhesion between covering 100 and a joint. It is to be appreciated, however, that a covering may have any number of protrusions and a protrusion may rounded, pointed, squared, or any other shape. In some embodiments, a protrusion may be scored and/or may have a plurality of bumps, indentations, ridges, or the like formed thereon.

In accordance with some embodiments of the present invention, one or more perforations of a covering may be straight, curved, or irregular. In preferred embodiments, a covering may have a plurality of substantially straight perforations which may be parallel to a lateral edge of the covering. For example, as illustrated in FIG. 3, a covering 200 may have a first perforation 210A, a second perforation 210B, and a third perforation 210C, each of which may be substantially parallel to a first edge 214 and a second edge 216. In preferred embodiments, one or more perforations may be formed in a covering such that, when the covering is separated at a perforation, equally sized and uniform partitions may be formed. For example, as further illustrated in FIG. 3, the distances between i) first edge 214 and first perforation 210A, ii) first perforation 210A and second perforation 210B, iii) second perforation 210B and third perforation 210C, and iv) third perforation 210C and second edge 216, represented by D₁, D₂, D₃, and D₄, respectively, may be substantially equal. It is to be understood, however, that each, or some, of distances D₁, D₂, D₃, and D₄ may be different from another. In some embodiments, a perforation may be oriented in a diagonal direction, relative to a lateral edge of a covering, such that the partitions of the covering have graduated widths (i.e., widths which increase or decrease in a lateral direction). For example, as illustrated in FIG. 4, a perforation 310 may be formed in a covering 300, extending from one corner to an opposite corner thereof.

In some embodiments, a covering may have one or more perforations which may be irregular (i.e., not straight). For example, a perforation may be curved and/or patterned (e.g., wave, sawtooth, semicircle, etc.) such that the resulting partitions of a covering are irregularly shaped. For instance, as illustrated in FIG. 5, a covering 400 may have a curved perforation 410, which may have a curvature that increases or decreases toward a lateral edge of covering 400. In some embodiments, a covering may be colored and may have decorative features or designs. For example, two or more colors may be used to distinguish between different types of coverings (e.g., to distinguish between coverings of varying thicknesses, widths, flexibility, partition sizes, etc.).

In accordance with some embodiments of the present invention, a covering may have edges which may be flat or rounded. In some embodiments, one or more edges may be chamfered or beveled which may useful in certain cases, such as when joining two coverings together. For example, as illustrated in FIG. 6A, a pair of coverings 500A and 500B may each have a chamfered edge which may be complementary to each other. Thus when, for example, coverings 500A and 500B are overlapped, or adjoined, such that the chamfered portions of each covering abut each other, the adjoined coverings may give the appearance of a smooth, continuous surface, as illustrated in FIG. 6B.

In some embodiments, a covering may have a slotted edge which may abuttingly engage, or mate with, a protruding edge of another covering, which may create a tight seal therebetween (i.e., having little or no play). A slotted edge and/or a protruding edge may be formed along a lateral edge, or a perforation, of a covering. For example, as illustrated in FIG. 7A, a covering 600 may have a slotted edge 610 and a covering 700 may have a complementary protruding edge 710 which may be inserted into, or mate, with slotted edge 610. When covering 600 and covering 700 are adjoined (i.e., when protruding edge 710 is inserted into slotted edge 610), there may be little to no play therebetween, as illustrated in FIG. 7B.

One or more coverings, as described herein, may be used to conceal and protect gaps or joints in artificial pools. In a preferred implementation, a covering (or plurality of coverings) may be used in a swimming pool to conceal an expansion joint between the top edge of a row of pool tiles and the bottom edge, or surface, of the pool deck or coping. For example, a method of concealing an expansion joint of a pool using a covering of plasticized material may include the steps of: (i) measuring the area to be sealed by the covering; (ii) cutting, or tearing, the covering according to the measured specifications; (iii) filling the joint with an effective amount of an adhesive (i.e., an amount which can create a sufficient bond) for the covering to bond to; (iv) extruding an effective amount of an adhesive on the side of the covering having a textured or scored surface; (v) either positioning the covering such that the adhesive coated side is placed over the joint, or inserting the covering (or portion thereof) within the joint; and (vi) pressing firmly down on the covering to ensure a sufficient bond with the adhesive within the joint.

When replacing an existing covering or concealing a sealed expansion joint, an existing joint seal may need to be removed first before filling with the joint with adhesive. For example, an existing seal may be damaged or cracked, which may prevent a strong bond from forming between a covering and the seal. Therefore, the existing seal may need to be removed (e.g., carved out and discarded) and resealed. In some cases, an existing seal may still be viable (e.g., without cracks or other types of damage), in which case a fresh layer of adhesive may be applied over the existing seal before bonding to a covering.

In some applications of the present invention, two or more coverings may be used to cover a relatively large area. For example, if the area to be covered is wider than a covering, a user may need to apply a second covering directly above or below a first covering to ensure complete coverage. In some implementations, a user may place a second covering over a first covering, such that a portion of the second covering overlaps the first covering, which may provide for a better seal therebetween. If coverings having beveled or chamfered edges are used, a user may overlap two coverings along the beveled portions thereof. If coverings having slots and/or protruding edges are used, a user may insert a protruding edge of a first covering into a complementary slot of a second covering before placing the coverings over the area to be concealed.

In some cases, such as, for example, for relatively small joints or gaps, a whole (i.e., unseparated) covering may not be needed to cover an entire area. Accordingly, a user may cut, or tear, a covering along a perforation to obtain a narrower partition. In other cases, an area to be sealed may not be uniform. For example, the width of an area to be sealed may increase or decrease in a lateral direction, requiring coverings of varying sizes. In such cases, a user may utilize, for example, a covering with partitions which may have graduated widths (i.e., a covering having a diagonally formed perforation) to account for non-uniform joints or gaps. For relatively large, non-uniform areas, an irregularly shaped partition of one covering may be combined with a covering which has not been cut, torn, or otherwise separated into partitions. For example, a partition of one covering with a graduated width may be placed above (or below) an unseparated covering in order to cover an area which is wider than a single unseparated covering, but has a variable width in a lateral direction. It is to be appreciated, however, that a user may utilize any number or type of coverings, and/or partitions thereof, and may also cut a covering into any desired shape or size in order to cover a given area.

It is to be understood that variations, modifications, and permutations of embodiments of the present invention may be made without departing from the scope thereof. It is also to be understood that the present invention is not limited by the specific embodiments, descriptions, or illustrations or combinations of either components or steps disclosed herein. Thus, although reference has been made to the accompanying figures, it is to be appreciated that these figures are exemplary and are not meant to limit the scope of the invention.
