  • Patent number: 8916242
    Abstract: A connector system facilitates the connection of a first tree trunk to a second tree trunk of an artificial tree system, and further protects one or more ends of a trunk when, for example, the artificial tree system is being shipped or stored. The connector system comprises a sleeve. The sleeve comprises a cylindrical shaped body. The outer of the body has a uniform cylindrical shape. The interior of the sleeve has different diameters at its top and bottom. The interior includes a notch or shoulder. The shoulder is in proximity to the top end of the sleeve. The sleeve further comprises a cutout for assisting with connecting and securing the trunks together.

  • Patent number: 8753135
    Abstract: A lamp system used in a light string system comprises a light assembly and a socket assembly. The light assembly comprises a light source, a base in communication with the light source, and a bypass activating system. The socket assembly comprises a socket adapted to receive the light assembly and a bypass mechanism having a first position and a second position. The bypass mechanism is in the first position when the light assembly is not seated in the socket assembly. When the bypass mechanism in the first position, current flows across the bypass mechanism. When the light assembly is inserted into the socket assembly, the bypass activating system of the light assembly moves the bypass mechanism into the second position, and current flows through the light source instead of the bypass mechanism.

  • Patent number: 8640275
    Abstract: Devices combining swimming pool skimmers, pumps, and removable, disposable filters into integral, sidewall-mounted systems for above-ground pools and other above-ground liquid containment enclosures, and methods for the use of such systems to remove both larger floating debris and smaller particulate matter to maintain water clarity and hygienic safety within such pools or like liquid containment enclosures are disclosed herein. Specifically, a ring-type above-ground pool comprising a base, a sidewall, and at least a portion of a cleaning system solely supported by the sidewall and mounted at a non-vertical angle such that it is substantially parallel to the sidewall.
