  • Patent number: 6625944
    Abstract: A connector for joining two elongate framing members in abutting right angle relationship to form either a right angle corner connection or T-connection between the framing members is disclosed. The connector can optionally include panel receiving means to receivingly support two rectangular panel sections in complimentary right angle relationship above or below the joined together framing members. Connectors which include the panel receiving means are useful in constructing containers such as planters or the like and which have upper and lower rectangular frames with the rectangular panel sections disposed therebetween and thus forming the sidewalls for the container.
    Type: Grant

  • Patent number: 5831391
    Abstract: An outdoor ground lighting system that includes one or more low voltage lamp units, provided from a step down transformer connectable to a high voltage AC power supply and an on/off timer operative to turn the lamps on for a selected time period during hours of darkness. Added to this known system is a secondary switching system that includes a solenoid operated switch connected to bypass the timer and a detector to detect the presence of a person or the like in the field of view of the detector. The detector provides an output signal in response to detecting the presence of someone and the solenoid switch is actuated by such signal to switch on the lamps when the timer is in the off cycle. The secondary switching system enhances the garden lighting system by providing a security lighting system when the timer is in an off mode.

  • Patent number: 5548500
    Abstract: A novel electrical lamp fixture of the type having a lamp housing, a housing axis, a housing sidewall co-axial with the housing axis and a lamp receiving socket supported interiorly of the housing by a housing support means is disclosed and is also of the type which has an exterior support for the housing and which is pivotally connected to the housing. By extending this pivot connection through an elongate slot provided in the co-axial sidewall of the housing, it is possible to adjust the relative angular positioning of the housing to its support and simultaneously adjust the location of the lamp receiving socket along a length of the housing axis in a one-step operation. Locating the lamp receiving socket in different axial positions within the housing is desired when light bulbs of different axial lengths are employed in the same lamp receiving housing.
