Extension pole

An extension pole, comprising:

• a base section and an extension section respectively defining a pair of laterally presented side faces;
• slide support means for slidably interconnecting said base and extension sections with their respective side faces disposed in mated face-to-face relation, and to permit longitudinal sliding displacement of said extension section between an extended position and a retracted position relative to said base section, said slide support means comprising a first slide cuff fixedly connected to said base section generally at an end thereof and including a sleeve slidably receiving and supporting said extension section, and a second slide cuff fixedly connected to said extension section generally at an end thereof and including a sleeve slidably receiving and supporting said base section;
• and
• lock means for releasibly clamping said base and extension sections with their respective side faces in face-to-face relation to releasibly lock said base and extension sections in a selected position of longitudinal adjustment, said lock means comprising a longitudinally extending pattern of laterally open detents formed in the side face of one of said base and extension sections, and at least one laterally protruding key carried on the other of said base and extension sections for reception into a selected one of said detents.

An extension pole, comprising:

• a base section having a generally semicircular cross sectional shape defining a substantially planar side face;
• an extension section having a generally semicircular cross sectional shape defining a substantially planar side face;
• a first slide cuff connected to said base section and including a sleeve providing means for slide-fit reception and support of said extension section;
• a second slide cuff mounted to said extension section and including a sleeve providing means for slide-fit reception and support of said base section;
• said first and second slide cuffs supporting said base and extension sections with their respective side faces in substantially mated face-to-face relation, to permit longitudinal sliding movement of said extension section relative to said base section to a selected position of longitudinal adjustment;
• said side face of said base section defining a longitudinally extending pattern of detents;
• at least one lock key carried by said extension section and seated into a selected one of said detents;
• and
• clamp means for releasingly clamping said base and extension sections with their respective side faces in face-to-face relation to retain said lock key in said selected detent and thereby lock said extension section in a selected position of longitudinal adjustment.

An extension pole, comprising:

• a base section having a laterally presented and generally planar side face;
• an extension section having a laterally presented and generally planar side face;
• slide support means for interconnecting said base and extension sections with their respective side faces disposed in mated face-to-face relation, and to permit longitudinal sliding displacement of said extension section between an extended position and a retracted position relative to said base section;
• and
• lock means for releasibly clamping said base and extension sections with their respective side faces in face-to-face relation, to releasibly lock said base and extension sections in a selected position of longitudinal adjustment, said lock means comprising a band clamp extending circumferentially about said base and extension sections, and a longitudinally extending pattern of laterally open detents formed in the generally planar side face of one of said base and extension sections, and at least one laterally protruding key carried on the other of said base and extension sections for reception into a selected one of said detents.

An extension pole, comprising:

• a base section having a laterally presented and generally planar side face;
• an extension section having a laterally presented and generally planar side face;
• slide support means for interconnecting said base and extension sections with their respective side faces disposed in mated face-to-face relation, and to permit longitudinal sliding displacement of said extension section between an extended position and a retracted position relative to said base section, said slide support means comprising a pair of slide cuffs each longitudinally fixed to a respective one of said base and extension sections and slidably supporting the other of said base and extension sections;
• and
• lock means for releasibly clamping said base and extension sections with their respective side faces in face-to-face relation, to releasibly lock said base and extension sections in a selected position of longitudinal adjustment.
