Abstract

Abstract A collapsible frame structure for a luggage assembly comprises two elongated bar members telescopically and movably received within two elongated tubular members at the lower ends thereof through skew holes provided on the receiving ends of the tubular members so as to make the bar members skew with respect to the tubular member and thus a frictional sleeve attached to the lower end of each of the bar members is in a frictional engagement with the inside surface of the respective tubular member. With such a frictional engagement, the bar members are allowed to move relative to the tubular members when forcibly pushed or pulled while capable of being maintained at any desirable position along the length of the tubular members.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 209 words
An extendible handle assembly for wheeled luggage comprising: a) a pair of cylindrical members for mounting to the luggage, each cylindrical member having a first central axis and a longitudinal hole extending therethrough, the longitudinal hole having a second central axis that is skewed with respect to the first central axis; b) a tubular member having a first and concentrically engaged on each cylindrical member and forming a noncoaxial extension of the longitudinal hole; c) a pair of elastically deformable elongate bar members, each bar member including an upper end and a lower end, a handle means joining the upper ends and each lower end being provided with a friction sleeve thereon; d) each bar member being slidably received through a longitudinal hole to dispose the lower end within a tubular member and permit the bar members to be disposed between fully extended and fully retracted positions by respectively pulling and pushing the handle means; and e) wherein each longitudinal hole deforms each elongate bar member in alignment with the second central axis, thereby urging each friction sleeve into frictional engagement against an internal wall of the tubular member to permit the bar members to be maintained at any desired position between the fully extended and fully retracted positions.
Claim 2
Dependent Claim 209 words
An extendible handle assembly for wheeled luggage comprising: a) a pair of cylindrical members for mounting to the luggage, each cylindrical member having a first central axis and a longitudinal hole extending therethrough, the longitudinal hole having a second central axis that is skewed with respect to the first central axis; b) a tubular member having a first and concentrically engaged on each cylindrical member and forming a noncoaxial extension of the longitudinal hole; c) a pair of elastically deformable elongate bar members, each bar member including an upper end and a lower end, a handle means joining the upper ends and each lower end being provided with a friction sleeve thereon; d) each bar member being slidably received through a longitudinal hole to dispose the lower end within a tubular member and permit the bar members to be disposed between fully extended and fully retracted positions by respectively pulling and pushing the handle means; and e) wherein each longitudinal hole deforms each elongate bar member in alignment with the second central axis, thereby urging each friction sleeve into frictional engagement against an internal wall of the tubular member to permit the bar members to be maintained at any desired position between the fully extended and fully retracted positions.
Claim 3
Dependent Claim 52 words
The support frame assembly of claim 1 wherein each cylindrical member includes a shoulder at a lower end thereof and each tubular member includes a closed lower end for engagement by the lower end of the bar member and terminate its sliding movement in the respective fully extended and fully retracted positions.
Claim 4
Dependent Claim 18 words
The support frame assembly of claim 1 wherein each friction sleeve is formed of a high friction material.
Claim 5
Dependent Claim 14 words
The support frame assembly of claim 3 wherein the high friction material includes rubber.
Claim 6
Dependent Claim 14 words
The support frame assembly of claim 3 wherein the high friction material includes plastic.
