BACKGROUND OF THE INVENTIONSwimming pools generally include a supply of water which is contained by a plurality of upright perimeter walls and a bottom wall. Often a deck area is positioned adjacent the upright walls and surrounds the pool to provide an area for people to walk around the pool.
The walls of the swimming pool are commonly made from concrete, metal or plastic. When the walls of the swimming pool are metal or plastic, a rubber or vinyl liner is often utilized. The liner is hung from a coping which is typically located at the top of the upright perimeter walls, and which typically surrounds the entire perimeter of the swimming pool.
Additionally, it is common to have a swimming pool cover. Swimming pool covers are generally divided into two major categories: (1) summer covers, and (2) winter covers. Summer covers are generally used to cover the surface of the pool during the swimming season so as to conserve the heat of the water in the pool, especially during the cooler spring and fall days and evenings. Summer covers, often referred to as solar covers, are generally made of a “bubble” type plastic film that has cells of air sealed between two plastic films. The air cells provide sufficient buoyancy to assist the cover in floating on the surface of the pool water. During the day, sunlight or radiant energy passes through the summer cover and is absorbed by the pool water, thereby heating the pool. During the evening, the summer cover assists in preventing heat loss from the surface of the water, thereby conserving the heat of the water in the pool.
Winter covers are generally intended to cover the pool during periods of extended non-use, typically from the fall, through the winter and into the following spring. One primary purpose of winter covers is to keep dirt and debris (e.g., fallen leaves, twigs, grass clippings, etc.) from entering the pool during the time period when the pool is not being used and not being cleaned. To perform this function, the perimeter of the winter cover is typically securely anchored to some component outside the pool perimeter, or directly to the pool perimeter. Various types of anchoring of the winter-type pool covers are known in the prior art. One type of pool cover, disclosed in U.S. Pat. No. 5,259,078 assigned to Cantar Corporation, discloses a cover that has a series of grid-like straps that are anchored at the outer portions of the pool in spaced-apart anchoring positions. A resilient attachment, such as a spring, attaches the securing strap to the anchor to ensure the maintenance of the cover in a taut condition. Other types of systems for securing pool covers, for either summer-type pool covers or winter-type pool covers are known in the prior art.
Additionally, swimming pool covers can be manually extended and retracted over the pool, or they can be automatically extended and retracted over the pool. In the case of automatic pool covers, a tracking system is typically used to position the pool cover. Such a tracking system, however, may also be used with manually extended pool covers. One type of tracking system comprises parallel tracks secured at the top of opposing side walls of the pool. The opposing tracks may be fastened directly to the pool deck above the side walls (typically referred to as a top track design), or they may be incorporated into the coping at the top of the pool's side walls (typically referred to as an under track design). Typically, the pool cover is maintained in a roll, around a roll shaft, at one end of the pool, and the roll may be maintained in a covered box, open to the air, or in a recess in the ground. A rope is sewn into the opposing side edges of the pool cover to form a bead along the opposing side edges of the cover. Each of the beads is retained in one of the opposing tracks. A motor or crank is coupled with the roll shaft and the ropes manipulates the cover into a closed and open position. Alternatively, if a motor is not utilized the system may be manipulated manually.
When used with a tracking system, the pool cover often has a leading edge bar that is attached to the leading edge of the pool cover (i.e., the downstream edge of the pool cover as the pool cover is being extended). The leading edge bar assists in maintaining the cover at a position above the pool water as the cover is moved from the open position (i.e., when the cover is on the roll and not covering the pool) to the closed position (i.e., when the cover is covering the pool), and the reverse. The leading edge bar typically extends substantially a distance equal to or slightly less than the width of the pool with an under-track system, and may extend any distance, greater to or less than the width of the pool, in a top-track system.
The leading edge bar of the tracking system is also connected to the tracks on the opposing side walls of the pool with a slider mechanism. A prior art slider mechanism connected to a leading edge bar of a pool cover tracking system is illustrated in prior art
Accordingly, a pool cover tracking system that reduces the drawbacks of the tracking systems in the prior art is desired. Such a system may provide a simple and inexpensive apparatus for providing a removable endcap for securing the slider assembly to the leading edge bar. Further, the endcap may provide vertical and lateral adjustment for the slider assembly.

BRIEF DESCRIPTION OF THE DRAWINGSTo understand the present invention, it will now be described by way of example, with reference to the accompanying drawings in which:
While this invention is susceptible of embodiments in many different forms, there is shown in the drawings and will herein be described in detail preferred embodiments of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the broad aspect of the invention to the embodiments illustrated.
Referring now in detail to the figures, and initially to
The Tracking System
As shown in
The motor coupled with the roll shaft 126 and the ropes 128, together with a pulley system 142 in the tracks 106, 108 manipulates the cover 102 into the closed and open position. Specifically, when the motor manipulates the roll shaft 126 and ropes 128 in one direction the pool cover 102 either opens or closes, and when the motor manipulates the roll shaft 126 and ropes 128 in the opposite direction the pool cover 102 moves in the opposite direction to either open or close the pool cover 102.
The Slider Assembly
As best shown in
The slider brackets 148 are then connected to their respective slider members 144, typically with the use of screws. In the embodiment disclosed, the slider brackets 148 have a plurality of apertures and the slider members 144 have either a plurality of tapped holes, or a plurality of through holes with a nut fixed on the opposing side of the slider members 144. In this manner the slider brackets 148 can then be fixed with the use of bolts and nuts to the slider members 144. It is understood, however, that the slider bracket 148 may be connected to the slider member 144 with a variety of commonly available methods and securing devices. Additionally, the slider member 144 may be fixed directly to the pool cover 102.
Further, the slider connector 146 is connected to the slider member 144. As best shown in
In one preferred embodiment, the means for connecting the slider connector 146 to the slider member 144 is similar to the means for connecting the slider bracket 148 to the slider member 144. As such, the slider connector 146 is bolted or screwed to the slider member 144. As is explained below in detail, the extension 150 of the slider connector 146 operatively engages the leading edge bar 110 of the pool cover tracking system 104. Alternatively, the slider connector 146 may be integral with and thus be a direct part of the slider member 144.
As shown in
The Connector
The connector 120 of the present invention is shown in
In a preferred embodiment, the first mating member 162 of the endcap 120 is one of a male mating member or a female mating member, and the second mating member 166 of the leading edge bar 110 is the other of the male mating member or the female mating member. In the embodiment disclosed, as shown in
Further, the first mating member 162 is adapted to mate with the second mating member 166 without any separate or additional retaining hardware such as screws, bolts, nuts, pins, etc. In the preferred embodiment the first mating member 162 slidingly engages and is frictionally retained in the second mating member 166. As such, the first mating member 162 of the endcap 120 is adapted to removably mate with the leading edge bar 110. In the preferred embodiment, the first mating member 162 of the endcap 120 is a protrusion that is dimensioned to fit snugly (i.e., a pressure fit) within the opening 167 of the second mating member 166 of the leading edge bar 110. A pressure fit is provided between the perimeter dimension of the protrusion or first mating member 162 of the endcap 120 and the interior dimensions of the second mating member 162 of the leading edge bar 110. The perimeter of the first mating member 162 comprises a portion that defines housing walls 170 for the cavity 168 of the endcap 120, and a plurality of ribs 172 depending from the housing walls 170. Utilizing ribs 172 instead of a solid member assists in decreasing both the mass and the weight of the overall endcap 120.
The connector 120 is attached to the respective slider assemblies 112, 114 adjacent the second end 160 of the endcap 120. As explained above, the second end 160 of the endcap 120 has a receiver 164 which is adapted to receive a component of the slider assembly 112, 114. In the preferred embodiments, shown in
As shown in
Each of the apertures 174 are dimensioned to receive a component of the slider assembly 112, 114. Typically, the component of the slider assembly 112, 114 that is received by the endcap 120 is the slider connector 146. As shown in the figures, a portion of the slider connector 146 of the slider assembly 112, 114 engages the aperture 174 in the endcap, and then extends into the cavity 168 of the endcap 120. While retained by the endcap 120, the slider connector 146 is free to slide back and forth in the cavity 168 of the endcap. As such, the slider connector 146 is said to be slidingly retained within the cavity 168 of the endcap 120, thereby connecting the slider assembly 112, 114 to the connector 120.
Through the components explained above, the connector 120 of the present invention provides both a vertical alignment means for vertically aligning the leading edge bar 110 respective to the track 106,108 of the pool cover tracking system, as well as a lateral alignment means for aligning the leading edge bar laterally about the pool. In one embodiment, the vertical alignment means comprises the receiver 164 adjacent the second end 160 of the endcap 120. Specifically, since the receiver 164 has a plurality of vertically arranged apertures 174, each of which is adapted to retain a component of the slider assembly. Since each of the apertures is located in different vertical positions, a vertical alignment means is produced because the receiver of the connector can receive the slider assembly in a plurality of vertical locations. Moreover, because the vertical alignment means comprises a plurality of apertures in the connector, the operator assembling the tracking assembly can vertically align the slider assembly 112, 114 during assembly of the slider assembly 112, 114 in the connector 120 by placing the slider component 146 in the appropriate aperture 174 of the receiver 164.
Conversely, the lateral alignment means of the present invention is in continual operation during use of the pool cover tracking system 104 of the present invention. In the preferred embodiment the lateral alignment means comprises the receiver 164 of the connector 120 which is adapted to receive a component of the slider assembly 112, 114, typically the extension 150 of the slider connector 146. As explained above, the receiver 164 allows the extension 150 of the slider connector 146 to freely move in opposing lateral directions within the endcap 120 during operation of the pool cover tracking system. Further, in a preferred embodiment, the lateral alignment means operates without fasteners. Accordingly, since the slider connector 146 is slidingly retained within the cavity 168 of the endcap 120, the slider connector 146 can move freely within the cavity 168 to assist in preventing jamming of the slider assemblies 112, 114 and the leading edge bar 110.
Accordingly, the connector 120 of the present invention provides a simple and inexpensive system for connecting a leading edge bar 110 to opposing tracks 106, 108 in a pool cover tracking system. As such, the present invention overcomes the deficiencies in the prior art pool cover tracking systems.
