Abstract
Abstract In a door bearing, a bearing arm having a bearing bore is fastened to a stationary construction, such as a door frame. A bearing pin which is axially displaceable in the door engages the bearing bore. In order to permit quick and simple release of the bearing in a minimum amount of space, an open recess is provided within the door. Through this open recess, the bearing pin can be reached manually or by means of a tool in order to withdraw it from the bearing bore.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
267 words
In a door bearing and door assembly for pivotally mounting the door on a supporting structure of a household refrigeration appliance; said door bearing including a bearing arm for securement to said supporting structure; said bearing arm having a bearing bore; an elongated bearing pin; said door including an elongated passage slidably receiving said elongated bearing pin; said elongated bearing pin having an operative position in which said bearing pin extends into said bearing bore; the improvement wherein said door has a recess adjoining said elongated passage in a length dimension thereof, said recess having an end wall; said recess having a dimension parallel to said length dimension; said dimension of said recess being sufficiently large to accommodate portions of said bearing pin in a withdrawn position thereof in which said bearing pin is clear of said bearing bore; an outwardly open port in said door communicating with said recess and extending transversely to said length dimension; said open port providing access to said bearing pin for displacing said bearing pin into said withdrawn position; wherein spring means is provided for urging said bearing pin into said operative position; and wherein engageable means is provided on said bearing pin in the zone of said recess for permitting manual displacement of said bearing pin between said operative and withdrawn positions by access through said port, said engageable means including a screw which extends transversely through said bearing pin, which provides a handle projecting from said port, and which has an end that is adapted to press against said end wall of said recess to immobilize said bearing pin.
Claim 2
Dependent Claim

In a door bearing and door assembly for pivotally mounting the door on a supporting structure of a household refrigeration appliance; said door bearing including a bearing arm for securement to said supporting structure; said bearing arm having a bearing bore; an elongated bearing pin; said door including an elongated passage slidably receiving said elongated bearing pin; said elongated bearing pin having an operative position in which said bearing pin extends into said bearing bore; the improvement wherein said door has a recess adjoining said elongated passage in a length dimension thereof, said recess having an end wall; said recess having a dimension parallel to said length dimension; said dimension of said recess being sufficiently large to accommodate portions of said bearing pin in a withdrawn position thereof in which said bearing pin is clear of said bearing bore; an outwardly open port in said door communicating with said recess and extending transversely to said length dimension; said open port providing access to said bearing pin for displacing said bearing pin into said withdrawn position; wherein spring means is provided for urging said bearing pin into said operative position; and wherein engageable means is provided on said bearing pin in the zone of said recess for permitting manual displacement of said bearing pin between said operative and withdrawn positions by access through said port, said engageable means including a screw which extends transversely through said bearing pin, which provides a handle projecting from said port, and which has an end that is adapted to press against said end wall of said recess to immobilize said bearing pin.
Claim 3
Dependent Claim
38 words
An assembly as defined in claim 1, further comprising an additional, outwardly open recess communicating with said elongated passage; said bearing arm extending into said additional recess and said bearing bore being in alignment with said elongated passage.
Claim 4
Dependent Claim
48 words
An assembly as defined in claim 1, wherein said passage terminates in a blind bore and said recess is situated between said bearing bore and said blind bore; and further wherein said spring means comprises a compression spring accommodated in said blind bore and engaging said bearing pin.
Claim 5
Dependent Claim
20 words
An assembly as defined in claim 1, wherein said engageable means further includes a groove provided in said bearing pin.
Claim 6
Dependent Claim
16 words
An assembly as defined in claim 4, wherein said groove extends circumferentially about said bearing pin.
Claim 7
Dependent Claim
102 words
An assembly as defined in claim 1, wherein said door has first and second sides, with said elongated passage, recess, and port being provided at said first side of said door; wherein said door has a further elongated passage, recess, and port at the second side thereof; and wherein said screw is releasably secured to said bearing pin so that said bearing pin, spring means, and screw can be transferred from said elongated passage, recess, and port to said further elongated passage, recess, and port to permit said door to be pivotally mounted at said second side rather than said first side.
