BACKGROUND OF THE INVENTION
Swimming pools generally include a supply of water which is contained by a,plurality of upright perimeter walls arid 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 IS 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 ° 52'10 P 008 ~ PATENT

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 ° 52'10 P 008 ~ PATENT
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. Patent 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 rrianually 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 5210 P 008 ~ PATENT

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 FIGS.
7A and 7B. As shown in prior art FIGS. 7A and 7B, the slider mechanism comprises a first component 10 that slides in the track, and a second component 12 which fixedly connects the first component 10 to the leading edge bar 14 of the prior art. In the prior art, the second component 12 comprises a bar having a slot 16 adjacent one end of the bar, and a hole pattern 18 on the opposing end of the bar. A third component 20 operates as a fixing plate to fixedly secure the second component I2 to the leading edge bar 14: The third component 20 has a plurality of thru holes which match up with tapped holes in the bottom wall 24 of the leading edge bar 14. Bolts 22 are placed through the thru holes in the third component 20, then the bolts extend through the slot 16 in the second component 12, and finally the bolts are secured into the tapped holes in the bottom wall 24 of the leading edge bar 14. As such, numerous components are required to connect the leading edge bar 14 to the track, and extended alignment time is required to properly align the leading edge bar 14. Further, while the slot 16 in the second component 12 initially allows for accurate location of the leading edge bar 14 2o relative to the first component 10 of the slider mechanism, once the bolts 22 are tightened, the second component 12 remains fixed in place to the leading edge bar 14.
Accordingly, no subsequent lateral or vertically alignment is possible. Thus, this type of prior-art system may induce tracking jams if one side becomes misaligned.
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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODllVIENTS
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.
1o Refernng now in detail to the figures, and initially to FIGS. 1 and 2, there is shown a swimming pool 100 having a pool cover 202 which utilizes the pool cover tracking system 104 of the present invention. Generally, the pool cover tracking system 104 comprises first and second opposing tracks 106, I08, a leading edge bar 110 connected to the pool cover 102, a first slider assembly 112 connecting a first end 116 of the leading edge bar 110 to the first track 106, and a second slider assembly 114 connecting a second end 118 of the leading edge bar 110 to the second track 108. The slider assemblies 112, 114 generally traverse in their respective tracks 106, 108 to assist in locating the pool cover 102. In the pool cover tracking system 104 of the present invention, a connector 120 is utilized to connect the slider assemblies 112, I 14 to the leading edge bar 110.
2o The Tracking System As shown in FIGS. 1 and 2, the opposing tracks 106, 108 of the pool cover tracking system I02 for the specific swimming pool 100 disclosed are mounted at the top of opposing sidewalls 122, I24 of the swimming pool 100. Depending on the specific type of swimming pool, the tracks 106, 108 are typically mounted either directly to the deck, and often above the sidewaIls, or they may be incorporated into the coping at the top of the sidewalls. As is understood by one of ordinary skill in the relevant art, the scope of the present invention is not dependent on the location of the tracks 106, I08. The pool cover 102 is wound around a reel or roll shaft 126, and the roll shaft 126 may be connected to a motor (not shown) to effectuate automatic opening and closing of the pool cover 102 on the swimming pool 100.
A rope or 3o cable 128 is connected, typically by sewing, into each of the opposing side edges I30, 132 of the pool cover 102 to form a bead 134 along the opposing side edges 130, 132 of the cover 102. As is shown in FIGS. 2 and 6, each of the beads 134, 136 is retained in one of the 52:10 P 008 ~ PATENT
opposing tracks 106, 108. Further, the beads 134,136 traverse longitudinally about the respective opposing tracks 106, 108 in the guide slots 138 in the tracks 106, 108.
Additionally; as explained in detail below, the tracks 106, 108 have a guide slot 140 to allow the slider assemblies I 12, 1 I4 to traverse longitudinally about the opposing tracks I06, 108.
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 1o direction to either open or close the pool cover 102.
The Slider Assembly As best shown in FIGS. 2 and 5, the slider assemblies I 12, I 14 comprise a slider member 144, a slider connector I46, and a slider bracket 148. For reference, the first slider assembly 112 is connected to the pool cover 102 adjacent the first side edge 130 of the pool cover, and the second slider assembly I14 is connected to the pool cover 102 adjacent the second side edge 132 of the pool cover. More specifically, with respect to the first side of the pool cover, the slider bracket 148 of the first slider assembly 112 is fixed to the pool cover 102 adjacent the first side edge 130 of the pool cover 102. In the embodiment disclosed, the slider bracket 148 is fixed to the pool cover 102 with two rivets. The slider bracket 148 of the 2o second side assembly 114 is fixed to the pool cover 102 adjacent the second side edge 132 of the pool cover 102 in the same manner.
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 I44. As best shown in FIGS. 5 and 6, in one embodiment the slider connector 146 is a bar that has a means for connecting it to the slider member I44 at a first end 145 of the slider connector 146, and 5210 P 008 ~ PATENT
an extension 150 extending distal therefrom. As shown in FIG. 6, the extension 150 may extend at the same angle as bar at the first end I45 of the slider connector 146 (i.e., the slider connector 146 may be substantially flat). Such a slider connector 146 is often utilized with an under-track system. Alternatively, as shown in FIG. 5, the extension 150 may extend at a 5 transverse angle to the first end I45 of the slider connector 146 such that the slider connector 146 has a bent or angled portion. Such a slider connector 146 is often utilized with a top-track system. Typically, if the slider member 144 traverses in the same plane as tracks I06, 108, then the extension 150 of the slider connector 146 will typically not extend at an angle to the first end 145 of the connector. Alternatively, if the slider member 144 traverses in a 10 transverse or different plane as the tracks 106, 108, then the extension 150 will typically extend at a transverse angle to the first end 145 of the slider connector 146.
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 I46 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 I10 of the pool cover tracking system I04.

As an example, an endcap 120 may only have one cavity, but three apertures. As such, each of the individual apertures provided in an endcap would access the same cavity.
Each of the apertures 174 are dimensioned to receive a component of the slider assembly 112, 114. Typically, the component of the slider assembly I 12, 114 that is received 2o 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 I68 of the endcap. As such, the slider connector 146 is said to be slidingly retained within the cavity 168 of the endcap f20, thereby connecting the slider assembly 112, l I4 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.
5210 P 008 ~ PATENT
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, l46 in the appropriate aperture I74 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 1o 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 I46. 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 I46 is sIidingly 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, l I4 and the leading edge bar 110.
Accordingly, the connector 120 of the present invention provides a simple and 2o 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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODllVIENTS
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.
1o Refernng now in detail to the figures, and initially to FIGS. 1 and 2, there is shown a swimming pool 100 having a pool cover 202 which utilizes the pool cover tracking system 104 of the present invention. Generally, the pool cover tracking system 104 comprises first and second opposing tracks 106, I08, a leading edge bar 110 connected to the pool cover 102, a first slider assembly 112 connecting a first end 116 of the leading edge bar 110 to the first track 106, and a second slider assembly 114 connecting a second end 118 of the leading edge bar 110 to the second track 108. The slider assemblies 112, 114 generally traverse in their respective tracks 106, 108 to assist in locating the pool cover 102. In the pool cover tracking system 104 of the present invention, a connector 120 is utilized to connect the slider assemblies 112, I 14 to the leading edge bar 110.
2o The Tracking System As shown in FIGS. 1 and 2, the opposing tracks 106, 108 of the pool cover tracking system I02 for the specific swimming pool 100 disclosed are mounted at the top of opposing sidewalls 122, I24 of the swimming pool 100. Depending on the specific type of swimming pool, the tracks 106, 108 are typically mounted either directly to the deck, and often above the sidewaIls, or they may be incorporated into the coping at the top of the sidewalls. As is understood by one of ordinary skill in the relevant art, the scope of the present invention is not dependent on the location of the tracks 106, I08. The pool cover 102 is wound around a reel or roll shaft 126, and the roll shaft 126 may be connected to a motor (not shown) to effectuate automatic opening and closing of the pool cover 102 on the swimming pool 100.
A rope or 3o cable 128 is connected, typically by sewing, into each of the opposing side edges I30, 132 of the pool cover 102 to form a bead 134 along the opposing side edges 130, 132 of the cover 102. As is shown in FIGS. 2 and 6, each of the beads 134, 136 is retained in one of the 52:10 P 008 ~ PATENT
opposing tracks 106, 108. Further, the beads 134,136 traverse longitudinally about the respective opposing tracks 106, 108 in the guide slots 138 in the tracks 106, 108.
Additionally; as explained in detail below, the tracks 106, 108 have a guide slot 140 to allow the slider assemblies I 12, 1 I4 to traverse longitudinally about the opposing tracks I06, 108.
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 1o direction to either open or close the pool cover 102.
The Slider Assembly As best shown in FIGS. 2 and 5, the slider assemblies I 12, I 14 comprise a slider member 144, a slider connector I46, and a slider bracket 148. For reference, the first slider assembly 112 is connected to the pool cover 102 adjacent the first side edge 130 of the pool cover, and the second slider assembly I14 is connected to the pool cover 102 adjacent the second side edge 132 of the pool cover. More specifically, with respect to the first side of the pool cover, the slider bracket 148 of the first slider assembly 112 is fixed to the pool cover 102 adjacent the first side edge 130 of the pool cover 102. In the embodiment disclosed, the slider bracket 148 is fixed to the pool cover 102 with two rivets. The slider bracket 148 of the 2o second side assembly 114 is fixed to the pool cover 102 adjacent the second side edge 132 of the pool cover 102 in the same manner.
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 I44. As best shown in FIGS. 5 and 6, in one embodiment the slider connector 146 is a bar that has a means for connecting it to the slider member I44 at a first end 145 of the slider connector 146, and 5210 P 008 ~ PATENT
an extension 150 extending distal therefrom. As shown in FIG. 6, the extension 150 may extend at the same angle as bar at the first end I45 of the slider connector 146 (i.e., the slider connector 146 may be substantially flat). Such a slider connector 146 is often utilized with an under-track system. Alternatively, as shown in FIG. 5, the extension 150 may extend at a 5 transverse angle to the first end I45 of the slider connector 146 such that the slider connector 146 has a bent or angled portion. Such a slider connector 146 is often utilized with a top-track system. Typically, if the slider member 144 traverses in the same plane as tracks I06, 108, then the extension 150 of the slider connector 146 will typically not extend at an angle to the first end 145 of the connector. Alternatively, if the slider member 144 traverses in a 10 transverse or different plane as the tracks 106, 108, then the extension 150 will typically extend at a transverse angle to the first end 145 of the slider connector 146.
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 I46 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 I10 of the pool cover tracking system I04.
Alternatively, the slider connector 146 may be integral with and thus be a direct part of the slider member 144.
As shown in FIG. 6, the slider member 144 also has a tracking groove 152 and a tracking extension 154. The tracking extension 154 of the slider member 144 mates with and traverses in a guide slot 140 in the track 106. Additionally, the tracking groove 152 of the slider member 144 engages and traverses about a rib 156 in the track 106 or 108. The rib 156 is adjacent the guide slot 140 in the track 106 and 108. The combination of the tracking groove 152 engaging the shoulder 156 in the track 106 or 108, and the tracking extension 154 engaging the slot 140 in the track I06 or 108 provides to retain the slider member 144 in sliding arrangement with the track 106 or 108 of the pool cover tracking assembly.
Accordingly, as the ropes 128 move the cover 102, the slider assemblies 112, 114 traverse in the opposing tracks 106, I08 to move the leading edge bar 110 with the pool cover 102.
The Connector 3o The connector 120 of the present invention is shown in FIGS. 3 and 4. As shown in FIGS. 5 and 6, the connector 120 of the present invention is utilized to connect the slider assemblies l I2, 114 to the leading edge bar 110.

As such, the male mating member 162 of the first end 158 of the endcap 120 is dimensioned such that it can be inserted into an opening 167 in the female mating member 166 of the leading edge bar 110 to connect the endcap 120 to the leading edge bar 110.
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 I20.
The connector 120 is attached to the respective slider assemblies 112, 114 adjacent the second end 160 of the endcap I20. 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 I12, 114.

The first aperture 174a provides access to the first cavity 168a, the second aperture 174b provides access to the second cavity I68b, and the third aperture 174c provides access to the third cavity I68c: Alternatively, less than one cavity for each aperture may exist. As an example, an endcap 120 may only have one cavity, but three apertures. As such, each of the individual apertures provided in an endcap would access the same cavity.
Each of the apertures 174 are dimensioned to receive a component of the slider assembly 112, 114. Typically, the component of the slider assembly I 12, 114 that is received 2o 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 I68 of the endcap. As such, the slider connector 146 is said to be slidingly retained within the cavity 168 of the endcap f20, thereby connecting the slider assembly 112, l I4 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.
5210 P 008 ~ PATENT
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, l46 in the appropriate aperture I74 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 1o 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 I46. 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 I46 is sIidingly 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, l I4 and the leading edge bar 110.
Accordingly, the connector 120 of the present invention provides a simple and 2o 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.
While the specific embodiments have been illustrated and described, numerous modifications come to mind without significantly departing from the spirit of the invention, and the scope of protection is only limited by the scope of the accompanying Claims.
