a break away view of applicant 39 s tracking design in the form of tracking 50 and attachment splice 52 the tracking 50 includes a channel 51 for receiving a movement piece of a flexible pool cover such as movement piece 33 shown in fig1 in sliding contact therein the attachment splice 52 sometimes referred to herein as a means for splicing is secured directly to the pool deck with screws 54 said screws 54 are sometimes referred to herein as attachment means the tracking 50 is then snapped downwardly upon the attachment splice 52 such that grip arms 56 of the tracking 50 extend into recesses 58 along the sides of the attachment splice 52 thus causing the tracking 50 to be held firmly against the pool deck the tracking 50 conceals the screws 54 thus providing for a more continuous aesthetic appearance and also preventing any loose screws from being exposed to pose a danger to swimmers tracking 50 further comprises a top surface for covering the attachment splice 52 thereby providing a continuous surface and an under surface opposite the top surface the grip arms 56 are preferably of a partially cylindrical shape and the channel 51 is preferably defined by a partially cylindrical boundary the recesses 58 are preferably defined by a partially cylindrical boundary as well it is to be understood that the terms u201c cylinder u201d.
