Abstract
Abstract A pivotal connection between a handle and a housing, where the handle includes a cylindrical opening, and the housing includes a pair of cylindrical openings on opposite sides of the housing and concentric with the handle opening. A sleeve with a central tubular opening is disposed within the housing and handle openings, and has an outer diameter substantially equal to the diameter of the housing and handle openings. A cylindrical pin has an outer diameter greater than the inner diameter of the sleeve tubular opening and is wedged into the sleeve tubular opening to bulge the sleeve outwardly into beveled portions of the handle opening. The connection is formed by first aligning the handle between housing portions so that openings therethrough are disposed substantially concentric to one another. Then, a tubular sleeve is located within the housing and handle openings. Finally, a pin having an outer diameter greater than the inner diameter of the tubular sleeve opening is wedged into the sleeve opening.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
94 words
A pivotal connection between a handle and a housing, comprising: a cylindrical opening through the handle having outwardly beveled portions at both ends thereof; a pair of cylindrical openings through said housing, said housing openings being concentric with and on opposite sides of the handle opening; a deformable sleeve with a central tubular opening, said sleeve having an outer surface in frictional contact with the handle opening, handle opening beveled portions, and housing openings; and a cylindrical pin disposed within said sleeve tubular opening and biasing said sleeve radially outwardly into said frictional contact.
Claim 2
Dependent Claim
94 words
A pivotal connection between a handle and a housing, comprising: a cylindrical opening through the handle having outwardly beveled portions at both ends thereof; a pair of cylindrical openings through said housing, said housing openings being concentric with and on opposite sides of the handle opening; a deformable sleeve with a central tubular opening, said sleeve having an outer surface in frictional contact with the handle opening, handle opening beveled portions, and housing openings; and a cylindrical pin disposed within said sleeve tubular opening and biasing said sleeve radially outwardly into said frictional contact.
Claim 3
Dependent Claim
12 words
The connection of claim 1, wherein said sleeve is made of plastic.
Claim 4
Dependent Claim
33 words
The connection of claim 1, wherein said handle is the locking handle of a window lock, and said handle is frictionally maintained in position relative to the housing until moved by an operator.
Claim 5
Dependent Claim
164 words
In a window lock having a handle with a grasping portion for grasping a keeper, said handle extending through a slot in a base housing and being pivotally connected thereto, said handle and housing pivotal connection comprising: a handle pivot portion disposed within said housing slot and having a cylindrical opening with a first diameter, each end of the cylindrical opening being tapered outwardly to a diameter greater than the first diameter; coaxial cylindrical openings on opposite sides of the housing slot, each of said housing openings having a selected diameter substantially equal to the first diameter; a plastic tubular sleeve within the housing openings and handle pivot portion cylindrical opening, said sleeve including an axial cylindrical opening and an outer surface; and a cylindrical pin disposed within said sleeve opening and biasing said sleeve radially outwardly beyond the first diameter with its outer surface in frictional engagement with the housing and handle cylindrical openings and the tapered ends of the handle cylindrical opening.
Claim 6
Dependent Claim
164 words
In a window lock having a handle with a grasping portion for grasping a keeper, said handle extending through a slot in a base housing and being pivotally connected thereto, said handle and housing pivotal connection comprising: a handle pivot portion disposed within said housing slot and having a cylindrical opening with a first diameter, each end of the cylindrical opening being tapered outwardly to a diameter greater than the first diameter; coaxial cylindrical openings on opposite sides of the housing slot, each of said housing openings having a selected diameter substantially equal to the first diameter; a plastic tubular sleeve within the housing openings and handle pivot portion cylindrical opening, said sleeve including an axial cylindrical opening and an outer surface; and a cylindrical pin disposed within said sleeve opening and biasing said sleeve radially outwardly beyond the first diameter with its outer surface in frictional engagement with the housing and handle cylindrical openings and the tapered ends of the handle cylindrical opening.
Claim 7
Independent Claim
127 words
A method for pivotally connecting a handle to a housing, comprising the steps of: aligning the handle between housing portions with openings through said handle and said housing portions being disposed substantially concentric to one another, with the handle opening having ends beveled outwardly to a diameter greater than the diameter of the housing portion openings; locating a sleeve within said housing and handle openings, said sleeve having a central tubular opening with a selected inner diameter no greater than the diameter of the housing portion openings; and forcing a pin into said sleeve tubular opening, said pin having an outer diameter greater than the sleeve opening inner diameter to deform said sleeve radially outwardly against said housing portion openings and into said handle opening beveled ends.
Claim 8
Independent Claim
127 words
A method for pivotally connecting a handle to a housing, comprising the steps of: aligning the handle between housing portions with openings through said handle and said housing portions being disposed substantially concentric to one another, with the handle opening having ends beveled outwardly to a diameter greater than the diameter of the housing portion openings; locating a sleeve within said housing and handle openings, said sleeve having a central tubular opening with a selected inner diameter no greater than the diameter of the housing portion openings; and forcing a pin into said sleeve tubular opening, said pin having an outer diameter greater than the sleeve opening inner diameter to deform said sleeve radially outwardly against said housing portion openings and into said handle opening beveled ends.
Claim 9
Dependent Claim
142 words
A pivotal connection between a handle and a housing, comprising: a cylindrical opening through the handle having outwardly beveled portions at both ends thereof; a pair of cylindrical openings through said housing, said housing openings being concentric with and on opposite sides of the handle opening; a cylindrical pin having a selected outer diameter; a deformable sleeve with a central tubular opening receiving said pin, said sleeve having an outer surface biased outwardly into frictional contact with the handle opening, handle opening beveled portions, and housing openings by providing a sleeve with an outer diameter substantially equal to or less than the diameter of said housing and handle openings and a tubular opening inner diameter less than the selected outer diameter of the pin, locating said sleeve within said housing and handle openings, and forcing said pin into said sleeve tubular opening.
Claim 10
