  • Patent number: 5315064
    Abstract: An improved suspended line cable breakaway device includes a first body portion for connecting to a first end of a support cable and a second body portion for connecting to a second end of the support cable. The first body portion includes resilient fingers having nubs, which are releasably received by slots contained in a cavity wall of the second body portion. A biased spreader, slidably contained in a cavity in the second body portion, is displacable axially along the cavity by an external force along the support cable to urge the nubs outwardly such that the second body portion is disengaged from the first body portion, simultaneously disconnecting component lines of a first end of a suspended line from corresponding component lines of a second end of the suspended line. A shield protects the component line connections, which are spaced internal to the device, from the elements.

  • Patent number: 5299384
    Abstract: A self-draining planter includes a container body with a container body sidewall having an opening. The sidewalls partially enclose an upwardly-open container body interior. A filter assembly includes inner and outer ends, a tubular member with inner and outer ends, a coupling mounted on the tubular member outer end and a screen wrapped around the tubular member with fluid passages therethrough. The tubular member inner end is closed and the tubular member includes a bore and a tube wall with tubular member openings communicating with its bore. The coupling extends through the container sidewall opening and is adjustably mounted on the container sidewall in disposition such that water is drained to a preselected level within the receptacle. The coupling includes a coupling bore communicating with the tubular member bore and open at the filter assembly outer end.

  • Patent number: 5028063
    Abstract: A folding step system includes a base assembly with approximate and distal ends, a link assembly with base and step ends, and a step assembly with approximate and distal ends. A base hinge assembly hingedly connects the base proximate end and the link assembly base end for rotational movement about a transverse rotational axis through an arc of movement between a retracted position adjacent to the base assembly and an extended position extending from the proximate end thereof. A step hinge assembly hingedly connects the link assembly distal end and the step proximate end for rotational movement about a transverse rotational axis between a retracted position adjacent to the link assembly and an extended position extending from the step end thereof.
