Abstract
Abstract A device for interconnecting a cabinet-like structure and a hingedly attached cover to frictionally support the cover in an open position is disclosed comprising a housing for attachment to the cabinet and an arm for attachment to the cover, which arm passes at least part way through the housing and also through a deformable bushing which is confined within the housing for limited movement therein. Relative movement of the arm and housing in a preselected direction deforms the bushing thereby increasing the frictional force opposing that relative motion. Relative motion in the opposite direction expands the bushing whereby it grips the arm less tightly so that during the limited movement of the bushing within the housing the frictional force drops to a second level, and when the bushing reaches one extreme of its permitted travel the arm and bushing execute a sliding motion causing the friction to increase somewhat to a third level which is less than its original level.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
142 words
A device for coupling two members together for limited movement of one member relative to the other and for providing an asymmetrical frictional force retarding relative movement therebetween comprising: a housing for attachment to one of the members; an arm for attachment to the other of the members, said arm passing at least part way through said housing and, at least in the vicinity of the housing, comprising a substantially straight rod of circular cross section; a bushing movable within the housing and at least partially surrounding said arm, said bushing having a circular aperture therein whereby said arm may pass through said bushing in frictional engagement therewith; and means responsive to relative movement of said arm and said housing in a preselected direction for deforming said bushing to thereby increase the frictional force opposing relative motion in the said preselected direction.
Claim 2
Independent Claim
142 words
A device for coupling two members together for limited movement of one member relative to the other and for providing an asymmetrical frictional force retarding relative movement therebetween comprising: a housing for attachment to one of the members; an arm for attachment to the other of the members, said arm passing at least part way through said housing and, at least in the vicinity of the housing, comprising a substantially straight rod of circular cross section; a bushing movable within the housing and at least partially surrounding said arm, said bushing having a circular aperture therein whereby said arm may pass through said bushing in frictional engagement therewith; and means responsive to relative movement of said arm and said housing in a preselected direction for deforming said bushing to thereby increase the frictional force opposing relative motion in the said preselected direction.
Claim 3
Dependent Claim
54 words
The device of claim 1 wherein one of the members is a cabinet and the other a lid hingedly attached thereto, said housing being provided with means for pivotably attaching the housing to an interior wall of the cabinet and said arm being provided with means for pivotably attaching the arm to the lid.
Claim 4
Dependent Claim
52 words
The device of claim 1 wherein the housing interior is of a fructroconical configuration and the exterior surface of said bushing is generally conically configured to mate therewith, said arm at least in the vicinity of the housing lying generally along an axis common to the housing interior and the bushing surface.
Claim 5
Dependent Claim
27 words
The device of claim 1 wherein said housing is provided with means at opposite ends thereof for passing said arm while obstructing the passage of said bushing.
Claim 6
Dependent Claim
54 words
The device of claim 3 wherein one of the members is a cabinet and the other a lid hingedly attached thereto, said housing being provided with means for pivotably attaching the housing to an interior wAll of the cabinet and said arm being provided with means for pivotably attaching the arm to the lid.
Claim 7
Independent Claim
191 words
A device for coupling a cabinet and a lid hingedly attached thereto together for limited movement of the lid relative to the cabinet comprising: an axially extending housing the interior of which is of a frustroconical configuration; means for pivotably attaching the housing to an interior wall of the cabinet; an arm for attachment to the lid, said arm passing at least part way through said housing and, at least in the vicinity of the housing, being in the form of a cylindrical rod extending generally along the housing axis; means for pivotably attaching the arm to the lid; a generally conically configured bushing movable within the housing to mate with the frustroconical housing interior and at least partially surrounding said arm, said bushing having a circular aperture therein whereby said arm may pass through said bushing in frictional engagement therewith whereby relative movement of said arm and said housing in a preselected direction deforms said bushing to thereby increase the frictional force opposing relative motion in the said preselected direction; and means at the opposite ends of said housing for passing said arm while obstructing the passage of said bushing.
Claim 8
Independent Claim
191 words
A device for coupling a cabinet and a lid hingedly attached thereto together for limited movement of the lid relative to the cabinet comprising: an axially extending housing the interior of which is of a frustroconical configuration; means for pivotably attaching the housing to an interior wall of the cabinet; an arm for attachment to the lid, said arm passing at least part way through said housing and, at least in the vicinity of the housing, being in the form of a cylindrical rod extending generally along the housing axis; means for pivotably attaching the arm to the lid; a generally conically configured bushing movable within the housing to mate with the frustroconical housing interior and at least partially surrounding said arm, said bushing having a circular aperture therein whereby said arm may pass through said bushing in frictional engagement therewith whereby relative movement of said arm and said housing in a preselected direction deforms said bushing to thereby increase the frictional force opposing relative motion in the said preselected direction; and means at the opposite ends of said housing for passing said arm while obstructing the passage of said bushing.
Claim 9
Dependent Claim
