  • Patent number: 6871362
    Abstract: The present invention 10 discloses a pair of end heads 28, 30 that are interconnected onto the inwardly disposed tube assembly 26 to form the pool cover 12 storage reel. Hand wheels 32 are rotationally attached to tube assembly 26 by end tubes 36 on the outside of the end heads 28, 30. Each of the end heads 28, 30 includes a pair of casters 40 mounted to the bottom surface of the end head. The tube assembly 26 consists of five components, a center tube 34, two outer tubes 36 and two end caps 42. The center tube is of larger diameter and allows for the two outer tubes to be telescopically inserted into the opposing distal ends. The cylindrically shaped tubes include mating male 48 and female 46 extrusions along the surfaces to ensure joint rotational movement of the tube assembly.

  • Patent number: 6725489
    Abstract: Disclosed are a plurality of different fasteners that can connect a vacuum pole 14 to an automatic pool cleaner 12 so that the user can selectively relocate and direct the pool cleaner 12 to locations in a pool 18 that were previously missed or not yet cleaned. The vacuum pole 14 is an extending cylindrical pole having a throughbore 34 wherein a pole attachment 26 having a similar construction may be inserted and secured, being held structurally by a compression clip 44 having securing pins 32 that compress to then extend through securing holes 34, and frictionally by protrusions 38 that align into depressions 40. Secured within, and extending outward from the pole attachments is a universal ball joint 26 connected within a connection member 42 cavity 43 to provide a highly maneuverable surface wherein a selected fastener may be attached. To connect the pole attachment's mating fastener to the automatic pool cleaner, a fastener attachment plate 56 is provided.
