## Background
BACKGROUND OF THE INVENTION
The present invention relates to pool covers and springs for attachment of the pool covers to pool decking. In particular, the present invention relates to apparatuses, systems, and methods for protecting pool decks from the pool cover springs.
In-ground pools are often covered for the “season” in areas of the country where weather prevents year round use, or for other reasons. Such covers are typically manufactured from mesh or other materials, and extend over the edge of the pool onto the pool decking. They are secured to anchors, usually in the form of a post, provided in the decking by the combination of straps and pool cover springs. Typically, the straps emanate from the pool cover itself and are attached to the posts by the pool cover springs. It will be appreciated that these springs expand and contract as water, snow, debris, wind, and the like exert ever-changing forces on the cover. This expansion and contraction has been known to mar the pool decking, which the springs generally rest on.
BRIEF SUMMARY OF THE INVENTION
It would therefore be advantageous to provide a device for protecting the decking from marring caused by this expansion and contraction. It would also be advantageous to provide a solution that remains affixed to the spring even when the pool cover is removed and stored. To achieve these results, the present invention provides, in one embodiment a pool spring cover comprising an elongate tubular member having a first opening on a first side and a second opening on a second side, the first side and second side spanning a longitudinal axis. An attachment member extends generally along the longitudinal axis from a first portion of the second side to a free end. A fastener comprised of a first fastener element and a second fastener element is provided. The first fastener element is associated with the attachment member at the free end and the second fastener element is associated with the tubular member at a second portion of the second side. The first and second fastener elements are adapted to fasten to each other such that the attachment member forms a loop.
The first fastener element and the second fastener element may form a one-time use fastener.
The association of the fastener element with the tubular element at the second portion of the second side may be at a portion of the tubular member generally opposed to the attachment member such that the loop extends across the second opening.
In another embodiment of the present invention, a pool cover spring system comprises a pool cover spring and a pool cover spring cover. The pool cover spring cover is formed from an elongate tubular member having an attachment member extending from a first end thereof, the attachment member having a first portion of a fastening device and the pool cover spring cover having a second portion of the fasting device at the first end thereof. At least a portion of the pool cover spring is provided inside the elongate tubular member and the first portion of the fastening device and the second portion of the fastening device are fastened together.
The second portion of the fastening device may be on an exterior surface of the pool cover spring cover.
The fastening device may a one-way fastener.
The spring may include a first connection element adapted to be connected to a strap of a pool cover, the attachment member being threaded through the first connection element. In such case, the first connection element may be substantially triangular. The spring may include a second connection element on an opposite end of the first connection element, the second connection element adapted to be connected to a pool deck fixture. The second connection element may be substantially circular.
The spring may comprise a first connection member and a second connection member, with a helical spring section therebetween, the at least a portion of the pool cover spring being at least a majority of the helical spring section.
The pool cover spring system may further comprise a second pool cover spring and a second pool cover spring cover. The second pool cover spring cover may be formed from an elongate tubular member having an attachment member extending from a first end thereof, the attachment member having a first portion of a fastening device and the pool cover spring cover having a second portion of the fastening device at a first end thereof. At least a portion of the second pool cover spring may be provided inside the elongate tubular member of the second pool cover spring cover and the first portion of the fastening device and the second portion of the fastening device of the second pool cover spring cover may be fastened together. The pool cover spring system may further comprise a pool cover, the pool cover spring and the second pool cover spring both being attached to the pool cover. The attachments may be by straps.
In a further embodiment of the present invention, a method of protecting pool decking from damage caused by pool cover springs is provided. The method comprises threading a pool cover spring device within the tubular body of a pool cover spring cover, the pool cover spring cover having an attachment member with a one-time use attachment device; threading the attachment member through a portion of the pool cover spring device; and connecting the attachment device of the attachment member to the tubular member to secure the pool cover spring cover to the pool cover spring device.
The connecting step may ensure that the tubular member does not travel along with the pool cover spring device as the spring expands and contracts.
The method may further comprise attaching the pool cover spring device to a pool cover at a first end of the pool cover spring device; and attaching the pool cover spring device to a fixture of a pool deck at a second end of the pool cover spring device.

DETAILED DESCRIPTION
In describing the preferred embodiments of the subject matter illustrated and to be described with respect to the drawings, specific terminology will be resorted to for the sake of clarity. However, the invention is not intended to be limited to the specific terms so selected, and it is to be understood that each specific term includes all technical equivalents which operate in a similar manner to accomplish a similar purpose.
Described herein are embodiments of the Pool Spring Cover and associated systems and methods of the present invention. Prior to addressing such embodiments, however, note is taken to FIG. 1, a perspective view of a conventional pool cover spring system in a partially installed condition. As shown, a pool P is provided with decking or a deck D. In order to protect the pool during the “off-season” or other times when it is desirous to cover the pool, a pool cover 10 may be provided over the pool P. Typically, the pool cover 10 will extend over the edge E of the pool P and onto the decking D. The pool cover P is provided with straps 12 spaced at intervals along the perimeter of the pool cover, although only one such strap is shown in FIG. 1. Likewise, the pool deck D is provided with anchors, such as posts 14, around the perimeter of the cover 10. The posts 14 are known in the pool installation arts and may be partially screwed into metal collars provided in the pool deck for use. When not in use, they may be completely screwed into the collars such that their upper surfaces are somewhat flush with the pool deck. In any event, it will be appreciated that there is typically one post 14 for each strap 12. The strap 12 is provided with a turnbuckle 16 to adjust its length, but is otherwise typically non-elastic. At the end of the strap 12 is a spring device 18, which effectively connects the strap to the post 14.
The spring device 18 is provided with a first connection element 20 which is typically substantially triangular and a second connection element 22 which is typically substantially circular. The connection elements 20, 22 each have extension members 24, 26 that extend between the two members in a parallel configuration, such that the first connection element 20 and second connection element 22 are on opposite ends of the spring device 18. The extension members 24, 26 each end in pairs of hooks 28, 30. Between the hooks 28, 30, and extending along the extension members 24, 26, is a helical spring 32. The helical spring 32 surrounds the extension members 24, 26 and is bound by the hooks 28, 30.
Although not shown in FIG. 1, when fully installed, the second connection element 22 is positioned over the post 14 such that the helical spring 32 is compressed by tensile forces acting on the spring device 18 from the strap 12 and cover 10. It will be appreciated, however, that the tensile forces are dynamic, and are lightened or increased at various times due to forces acting on the pool cover 10. A lightening of the force permits the helical spring 32 to expand, moving the first connection element 20 farther from the second connection element 22. An increase of force, on the other hand, causes the helical spring 32 to compress between the hooks 28, 30 as the first connection element 20 is spread further apart from the second connection element 22.
It will be appreciated that this expansion and contraction of the helical spring 32 often causes the spring device 18 to rub against the deck D, possibly marring or even damaging the deck. In order to protect the deck D, and even to shield the helical spring 32 from some environmental exposure, the spring device 18 may be provided with an inventive pool spring cover. An embodiment of one such cover is shown in FIG. 2.
As shown in FIG. 2, a first embodiment of the pool spring cover 100 is formed from an elongate tubular member 102 having a first opening 104 on a first side 106 and a second opening 108 on a second side 110. The first and second sides 106, 110 span a longitudinal axis 112 of the elongate tubular member 102. An attachment member 114, formed as an integral piece with the tubular member 102 in this embodiment, extends from a first portion 116 of the second side 110 to a free end 118. At the free end 118 is a first fastener element 120.
At a second portion 122 of the second side 110 of the tubular member 102 is a second fastener element 124. It will be appreciated that in this embodiment, the second portion 122 of the second side 110 is provided directly opposite to the first portion 116 of the second side such that the second fastener element 124 is approximately 180 degrees around the tubular member 102 from the attachment member 114 and the first fastener element 120. In other embodiments, the two fastener elements 120, 124 need not be 180 degrees apart.
As shown in FIG. 3A, the tubular member 102 of the pool spring cover 100 may be fitted over the helical spring 32 portion of the spring device 18 such that the second side 110 of the pool spring cover 100 is adjacent to the substantially triangular first connection element 20. The attachment member 114 may then be threaded through the substantially triangular first connection element 20 and the first fastener element 120 fastened to the second fastener element 124.
It is noted here that the tubular member 102 and attachment member 114 of the pool spring cover 100 are depicted in certain of the figures as being transparent. They may be. However, they may also be translucent or opaque depending on the materials used. In preferred embodiments, the material used is relatively flexible and exhibits a resiliency to environmental breakdown to permit its use for several years. A preferred material of construction is flexible colored PVC with UV additive. In one example of a device configured with flexible colored PVC with UV additive, the device features a durometer reading of approximately 83, an overall outside diameter of approximately 1.5′′, an inside diameter of approximately 1.35′′, and an overall length (of the tubular member) of 7.5′′. Other suitable dimensions, materials, and material features may also be provided.
Moving to FIG. 3B, there is depicted a top plan view of the pool spring cover 100 of FIG. 2. Of note is the first fastener element 120. In the embodiment shown in FIG. 3B, the first fastener element 120 is a one-way fastener, which may also be referred to as a one-time use fastener. Such fasteners are known in other arts and may include physical interference members (not shown) that prohibit unfastening of the fastener without compromising its integrity once fastened. In this application, this helps to ensure that the fastener does not come undone over time as often these types of fasteners are more resilient than others. Nevertheless, in other embodiments fasteners may be formed from standard multiple-use fasteners, such as snaps, hook and loop type fasteners, buttons, or ties. In still further arrangements, the fasteners may be substituted out and the attachment member 114 may be connected to the tubular member 102 through welding, such as chemical or heat welding, various adhesives, or other means.
FIG. 3C depicts a bottom plan view, and FIG. 3D depicts a side view, of the pool spring cover 100 of FIG. 2. In these views, it may be seen that attachment member 114 is formed integrally with the tubular member 102 in this embodiment.
FIG. 4 depicts a perspective view of a pool spring cover in accordance with a second embodiment of the present invention. This second embodiment of the pool spring cover 200 shares many features with the first embodiment, including its formation from an elongate tubular member 202 having a first opening 204 on a first side 206 and a second opening 208 on a second side 210. The first and second sides 206, 210 span a longitudinal axis 212 of the elongate tubular member 202. An attachment member 214 is also included. However, in this embodiment, the attachment member 214 is a separate piece from the tubular member 202. Thus, a connector 215 is provided to attach the attachment member 214 to the tubular member 202 at a first portion 216 of the second side 210 thereof. The attachment member 214 includes a free end 218 opposite the connector 215, which is provided with a first fastener element 220.
It is noted here that the connector 215 may be provided as any of the same structures as the fasteners of the prior embodiment, including one-way or one-time fasteners, snaps, hook and loop type fasteners, buttons, or ties. In addition, the connection may be by welding, such as chemical or heat welding, through adhesives, or the like.
At a second portion 222 of the second side 210 of the tubular member 202 is a second fastener element 224. The second fastener element 224 may be approximately 180 degrees around the tubular member 202 from the attachment member 214 and the first fastener element 220, as shown, or may be at other locations.
As shown in FIG. 5A, the tubular member 202 of the pool spring cover 200 may be fitted over the helical spring 32 portion of the spring device 18 such that the second side 210 of the pool spring cover 200 is adjacent to the substantially triangular first connection element 20. The attachment member 114 may then be threaded through the substantially triangular first connection element 20 and the first fastener element 220 fastened to the second fastener element 224.
In FIG. 5B, there is depicted a top plan view of the pool spring cover 200 of FIG. 4. FIG. 5C depicts a bottom plan view, and FIG. 5D depicts a side view, of the pool spring cover 200 of FIG. 4. In these views, it may be seen that attachment member 214 is formed as a separate component than tubular member 202.
FIG. 6 depicts a perspective view of a pool cover spring system in a partially installed condition and FIG. 7 depicts a top plan view of the pool cover spring system of FIG. 6 in an installed condition. Here it is shown that pool cover 10 may be attached to a post 14 through a strap 12 and spring device 18 in the conventional manner. However, an additional pool spring cover 100 (or 200) may be added. As previously discussed, in order to add the pool spring cover 100 the spring device 18 may be threaded through the tubular member 102 prior to being engaged with the post 14. The attachment member 114 may then be threaded through the first connection element 20 and securely fastened by bringing first fastener element 120 in connection with the second connection element (not shown in FIG. 6). Once the pool spring cover 100 is so fitted, the second connection element 22 may be positioned over the post 14 as shown in FIG. 7 in the otherwise conventional manner.
It will be appreciated that the pool spring cover 100 will stay over top of the spring device 18 by virtue of the attachment member 114 being threaded through the first connection element 20 on the one side, and the second connection element 22 being fitted over the post 14 on the other. In other words, there is no physical location for the tubular member 102 to travel other than along with first connection element 20 as the spring device 18 expands and contracts. In this configuration, the tubular member 102 effectively protects the pool deck from damage by marring. The tubular member 102 provides the added benefit of creating a safe place for a user to grasp the spring device 18 without the need for gloves or other protective gear.
Although the invention herein has been described with reference to particular embodiments, it is to be understood that these embodiments are merely illustrative of the principles and applications of the present invention. It is therefore to be understood that numerous modifications may be made to the illustrative embodiments and that other arrangements may be devised without departing from the spirit and scope of the present invention as defined by the appended claims.
