Abstract:
A vacuum cleaner connector for attachment to a vacuum cleaner hose end, comprising:a) an adaptor member, and; b) a tool member; c) wherein, said adaptor member comprising an adaptor port end, a adaptor pivot end, and a first air passageway through said adaptor member from said adaptor port end to said adaptor pivot end; d) wherein, said adaptor port end comprises an elongated conduit with less than five degrees taper for removable attachment by friction fit to a vacuum cleaner hose end, and said adaptor port end defining a first longitudinal axis aligned with the central axis of said elongated conduit; e) wherein, said tool member comprising a tool port end, a tool pivot end, and a second air passageway through said tool member from said tool port end to said tool pivot end; f) wherein, said tool port end comprises an elongated tube with a tapered exterior surface having less than five degrees of taper for removable attachment by friction fit to a vacuum cleaner tool, and said tool port end defining a second longitudinal axis aligned with the central axis of said elongated tube; g) further including, a pivot joint defined on said adaptor pivot end and said tool pivot end for pivotally connecting said adaptor member and said tool member to each other with said first and second air passageways forming a substantially sealed and continuous air passageway from the end of said adaptor port end to the end of said tool port end; h) wherein, said pivot joint defines an axis of rotation oriented at an acute angle with respect to both said first longitudinal axis and said second longitudinal axis, whereby a pivot angle between the first and second longitudinal axises may be changed by rotating said adaptor member with respect to said tool member i) wherein, a first pivot angle is defined by the acute angle between the first longitudinal axis and the axis of rotation, wherein a second pivot angle is defined by the acute angle between the second longitudinal axis and the axis of rotation; wherein said first and second pivot angles are within the range of ten degrees to eighty degrees; and j) wherein, the absolute value of the result of the first pivot angle minus the second pivot angle is less than ten degrees, whereby the first and second longitudinal axis can be rotated to less than ten degrees from the in-line position; k) wherein, the sum of the first and second pivot angles is greater than fifty degrees, whereby the first and second longitudinal axis can be rotated to greater than fifty degrees from the in-line position; and l) further including, a means for creating friction within the pivot joint to resist rotation of said pivot tool end with respect to said pivot adaptor end for hold said adaptor member and said tool member together at a stable angle during use, whereby said vacuum cleaner tool may be used for cleaning.
