Abstract
Abstract In order to provide a more compact package for economical storage and shipment, of a vacuum cleaner, or the like, the handle is manufactured in two portions. The two portions are configured to fit together in a predetermined manner with a telescoping relationship and to concomitantly complete electrical connections through connectors which are affixed to and internal to respective handle portions. At least one of the electrical connectors is allowed some longitudinal and rotational motion relative to its handle portion to facilitate electrical connector engagement and alignment. The assembly is held together by a fastener passing through the telescoped handle portions and one of the connectors. A portion of one of the connector assemblies also serves to limit the excursion of a compression spring surrounding a portion of the associated handle portion.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
259 words
A longitudinal hollow handle for an electrical appliance and comprising in cooperative combination: (a) first and second handle portions configured for limited and polarized telescoping engagement; (b) first and second electrical connectors associated with and interior of said first and second handle portions, respectively, for completing an electrical connection therebetween when said first and second handle portions are positioned in said polarized telescoping engagement; (c) first means for locking said first electrical connector within said first handle portion with a first predetermined and polarized orientation with respect thereto so that only limited relative rotational and/or longitudinal motion therebetween is possible; (d) second means for locking said second electrical connector within said second handle portion with a second predetermined and polarized orientation with respect thereto so that only limited relative rotational and/or longitudinal motion therebetween is possible; (e) third means for locking said second electrical connector within said second handle portion as aforedescribed; (f) fastening means penetrating both of said first and second handle portions and said first electrical connector when said first and second handle portions are positioned in limited and polarized telescoping engagement for retaining said first and second handle portions in a predetermined relationship; and (g) a sleeve associated with said first electrical connector for providing a passageway for said fastening means and for concomitantly preventing electrical conductors associated with said first electrical connector from interfering with the placement of said fastening means, said sleeve comprising a separate part, and said sleeve including spring wing members for locking said sleeve in association with said first electrical connector.
Claim 2
Dependent Claim
259 words
A longitudinal hollow handle for an electrical appliance and comprising in cooperative combination: (a) first and second handle portions configured for limited and polarized telescoping engagement; (b) first and second electrical connectors associated with and interior of said first and second handle portions, respectively, for completing an electrical connection therebetween when said first and second handle portions are positioned in said polarized telescoping engagement; (c) first means for locking said first electrical connector within said first handle portion with a first predetermined and polarized orientation with respect thereto so that only limited relative rotational and/or longitudinal motion therebetween is possible; (d) second means for locking said second electrical connector within said second handle portion with a second predetermined and polarized orientation with respect thereto so that only limited relative rotational and/or longitudinal motion therebetween is possible; (e) third means for locking said second electrical connector within said second handle portion as aforedescribed; (f) fastening means penetrating both of said first and second handle portions and said first electrical connector when said first and second handle portions are positioned in limited and polarized telescoping engagement for retaining said first and second handle portions in a predetermined relationship; and (g) a sleeve associated with said first electrical connector for providing a passageway for said fastening means and for concomitantly preventing electrical conductors associated with said first electrical connector from interfering with the placement of said fastening means, said sleeve comprising a separate part, and said sleeve including spring wing members for locking said sleeve in association with said first electrical connector.
Claim 3
Dependent Claim
258 words
A longitudinal hollow handle for an electrical appliance and comprising in cooperative combination: (a) first and second handle portions configured for limited and polarized telescoping engagement; (b) first and second electrical connectors associated with and interior of said first and second handle portions, respectively, for completing an electrical connection therebetween when said first and second handle portions are positioned in said polarized telescoping engagement; (c) first means for locking siad first electrical connector within said first handle portion with a first predetermined and polarized orientation with respect thereto so that only limited relative rotational and/or longitudinal motion therebetween is possible; (d) second means for locking said second electrical connector within said second handle portion with a second predetermined and polarized orientation with respect thereto so that only limited relative rotational and/or longitudinal motion therebetween is possible; (e) third means for locking said second electrical connector within said second handle portion as aforedescribed; (f) fastening means penetrating both of said first and second handle portions and said first electrical connector when said first and second handle portions are positioned in limited and polarized telescoping engagement for retaining said first and second handle portions in a predetermined relationship; (g) said third locking means comprising a spring wing member having a projection which projects through a perforation in said second handle portion, and said projection on said spring wing member which projects through said perforation in said second handle portion serving to limit the longitudinal motion in one direction, of a compression spring surrounding the exterior of said second handle portion.
Claim 4
Dependent Claim
258 words
A longitudinal hollow handle for an electrical appliance and comprising in cooperative combination: (a) first and second handle portions configured for limited and polarized telescoping engagement; (b) first and second electrical connectors associated with and interior of said first and second handle portions, respectively, for completing an electrical connection therebetween when said first and second handle portions are positioned in said polarized telescoping engagement; (c) first means for locking siad first electrical connector within said first handle portion with a first predetermined and polarized orientation with respect thereto so that only limited relative rotational and/or longitudinal motion therebetween is possible; (d) second means for locking said second electrical connector within said second handle portion with a second predetermined and polarized orientation with respect thereto so that only limited relative rotational and/or longitudinal motion therebetween is possible; (e) third means for locking said second electrical connector within said second handle portion as aforedescribed; (f) fastening means penetrating both of said first and second handle portions and said first electrical connector when said first and second handle portions are positioned in limited and polarized telescoping engagement for retaining said first and second handle portions in a predetermined relationship; (g) said third locking means comprising a spring wing member having a projection which projects through a perforation in said second handle portion, and said projection on said spring wing member which projects through said perforation in said second handle portion serving to limit the longitudinal motion in one direction, of a compression spring surrounding the exterior of said second handle portion.
Claim 5
Dependent Claim
35 words
The combination as set forth in claim 2 wherein said compression spring acts on the projection member projecting through said perforation for biasing said second electrical connector towards one limit of its limited longitudinal motion.
