Adjustable height mechanism for a dishwasher rack

An adjustable position apparatus for selectively varying the position of a first member relative to a second member, comprising:

• a first housing mounted upon said first member;
• a second housing mounted upon said second member;
• support means, for movably supporting said first member upon said second member, movably disposed within said second housing of said second member;
• elongated arm means mounted upon said support means and having a plurality of first locking means disposed in a linearly spaced array thereon for defining a plurality of incremental positions to which said first member may be adjusted with respect to said second member;
• second locking means mounted upon said first housing for operatively cooperating with said plurality of first locking means provided upon said arm means so as to maintain said first member at a particularly desired adjusted position with respect to said second member when said second locking means is engaged with a particular one of said plurality of first locking means defining said plurality of incremental positions;
• first guide means defined upon said arm means;
• second guide means provided upon said first housing for operatively cooperating with said first guide means of said arm means so as to guide movements of said second locking means of said first housing with respect to said first locking means of said arm means when said first housing and said first member are moved with respect to said second member so as to positionally adjust the disposition of said first member with respect to said second member;
• and
• actuating means mounted upon said first housing and operatively connected to said second locking means for selectively moving said second locking means of said first housing into and out of engagement with said first locking means of said arm means when said first member is to be moved with respect to said second member so as to positionally adjust the disposition of said first member with respect to said second member.

An adjustable position apparatus for selectively varying the elevational position of a dishwasher rack relative to a dishwasher cabinet, comprising:

• a first housing mounted upon said dishwasher rack;
• a second housing mounted upon a wall portion of said dishwasher cabinet;
• support means, for movably supporting said dishwasher rack upon said dishwasher cabinet, movably disposed within said second housing of said wall portion of said dishwasher cabinet;
• elongated arm means mounted upon said support means and having a plurality of first locking means disposed in a linearly spaced array thereon for defining a plurality of incremental positions to which said dishwasher rack may be adjusted with respect to said dishwasher cabinet;
• second locking means mounted upon said first housing for operatively cooperating with said plurality of first locking means provided upon said arm means so as to maintain said dishwasher rack at a particlarly desired adjusted position with respect to said dishwasher cabinet when said second locking means is engaged with a particular one of said plurality of first locking means defining said plurality of incremental positions;
• first guide means provided upon said arm means;
• second guide means provided upon said first housing for operatively cooperating with said first guide means of said arm means so as to guide movements of said second locking means of said first housing with respect to said first locking means of said arm means when said first housing and said dishwasher rack are moved with respect to said dishwasher cabinet so as to positionally adjust the disposition of said dishwasher rack with respect to said dishwasher cabinet;
• and
• actuating means mounted upon said first housing and operatively connected to said second locking means for selectively moving said second locking means of said first housing into and out of engagement with said first locking means of said arm means when said dishwasher rack is to be moved with respect to said dishwasher cabinet so as to positionally adjust the disposition of said dishwasher rack with respect to s&id dishwasher cabinet.
