Abstract
A housing assembly includes a housing having an access opening and a cover movable between a closed position wherein the cover generally covers the access opening and an open position wherein the cover generally does not cover the access opening. The assembly further includes a protrusion located on one of the housing or the cover, and a track located on the other one of the housing or the cover. The protrusion is slidably received in the track, and the track forms a generally closed loop shape such that the protrusion slides in the track when the cover is moved between the open and the closed positions. Additionally ramps may be provided on portions of the track to provide user feed back and to inhibit reverse motion of the protrusion.
Claims26
A housing assembly comprising:
- a housing having an access opening wherein said housing is a housing of at least one of a printer, copier, facsimile machine or scanner;
- a cover movable between a closed position wherein said cover generally covers said access opening and an open position wherein said cover generally does not cover said access opening;
- a protrusion located on one of said housing or said cover;
- and
- a track located on the other one of said housing or said cover, said protrusion being slidably received in said track, and wherein said track forms a generally closed loop shape such that said protrusion slides in said track when said cover is moved between said open and said closed positions.

A housing assembly comprising:
- a housing having an access opening;
- a cover movable between a closed position wherein said cover generally covers said access opening and an open position wherein said cover generally does not cover said access opening;
- a protrusion located on one of said housing or said cover;
- and
- a track located on the other one of said housing or said cover, said protrusion being slidably received in said track, and wherein said track forms a generally closed loop shape such that said protrusion slides in said track when said cover is moved between said open and said closed positions wherein said track includes a first rest location and a second rest location, each rest location being a relatively low or a relatively high location such that any immediately adjacent portions of said track extend generally upwardly or generally downwardly away from the associated rest location, and wherein said protrusion is located in said first rest location when said cover is in said closed position and wherein said protrusion is located in said second rest location when said cover is in said open position.

A housing assembly comprising:
- a housing having an access opening;
- a cover movable between a closed position wherein said cover generally covers said access opening and an open position wherein said cover generally does not cover said access opening;
- a protrusion located on one of said housing or said cover;
- and
- a track located on the other one of said housing or said cover, said protrusion being slidably received in said track, and wherein said track forms a generally closed loop shape such that said protrusion slides in said track when said cover is moved between said open and said closed positions wherein said cover is movably coupled to said housing such that said cover is movable relative to said housing only in a pivotable movement about a single fixed axis.

A housing assembly comprising:
- a housing having an access opening:
- a cover movable between a closed position wherein said cover generally covers said access opening and an open position wherein said cover generally does not cover said access opening;
- a protrusion located on one of said housing or said cover;
- and
- a track located on the other one of said housing or said cover, said protrusion being slidably received in said track, and wherein said track forms a generally closed loop shape such that said protrusion slides in said track when said cover is moved between said open and said closed positions, and wherein said track includes means to allow movement of said protrusion in a first direction and to generally block movement of said protrusion in a second direction.

A housing assembly comprising:
- a housing having an access opening;
- a cover pivotably coupled to said housing and movable between a closed position wherein said cover generally covers said access opening and an open position wherein said cover generally does not cover said access opening;
- a protrusion located on one of said housing or said cover;
- and
- a track located on the other one of said housing or said cover, said protrusion being slidably received in said track, and wherein said track forms a generally closed loop shape such that said protrusion slides in said track when said cover is moved between said open and said closed positions, said track comprising:
- a first rest location and a second rest location with said second rest location being generally above said first rest location, each rest location being a relatively low or a relatively high location such that any immediately adjacent portions of said track extend generally upwardly or generally downwardly away from the associated rest location, and wherein said protrusion is located in said first rest location when said cover is in said closed position and wherein said protrusion is located in said second rest location when said cover is in said open position;
- and
- a first, second, third and fourth portions, said first portion extending from said first rest location to a first intermediate location generally above said first rest location, said second portion extending from said first intermediate location to said second rest location generally below said first intermediate location wherein said first portion generally forms an angle with said second portion at said first intermediate location, said third portion extending from said second rest location to a second intermediate location generally above said second rest location wherein said third portion generally forms an angle with said second portion at said second rest location, and said fourth portion extending from second intermediate location to an intersection location with said first portion wherein said fourth portion generally forms an angle with said third portion at said second intermediate location, said fourth portion generally forms an angle with said first portion at said intersection location and said intersection location is generally above said first rest location.
