Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 203 words
A device for mounting a front panel of a drawer, said device comprising: a holding element fastenable to the front panel; a fastening element to be fixed to a side wall of the drawer; a hook member extending substantially perpendicular to the front panel and having a first end including means for engaging said holding element; means for mounting a second end of said hook member for pivotal movement about an axis extending substantially horizontally and parallel to the front panel, and for selectively shifting said hook member and said holding element relative to said fastening element in a direction perpendicularly of the front panel, thereby clamping the front panel in a mounted position; means, operable between said fastening element and said hook member, for selectively moving said hook member and said holding element laterally relative to said fastening element, and thereby for adjusting the relative horizontal position of the front panel with respect to the drawer; and means, operable between said fastening element and said hook member, for selectively pivoting said hook member and said holding member about said axis relative to said fastening element, and thereby for adjusting the relative vertical position of the front panel with respect to the drawer.
Claim 2
Independent Claim 203 words
A device for mounting a front panel of a drawer, said device comprising: a holding element fastenable to the front panel; a fastening element to be fixed to a side wall of the drawer; a hook member extending substantially perpendicular to the front panel and having a first end including means for engaging said holding element; means for mounting a second end of said hook member for pivotal movement about an axis extending substantially horizontally and parallel to the front panel, and for selectively shifting said hook member and said holding element relative to said fastening element in a direction perpendicularly of the front panel, thereby clamping the front panel in a mounted position; means, operable between said fastening element and said hook member, for selectively moving said hook member and said holding element laterally relative to said fastening element, and thereby for adjusting the relative horizontal position of the front panel with respect to the drawer; and means, operable between said fastening element and said hook member, for selectively pivoting said hook member and said holding member about said axis relative to said fastening element, and thereby for adjusting the relative vertical position of the front panel with respect to the drawer.
Claim 3
Dependent Claim 42 words
A device as claimed in claim 1, wherein said holding element has therein a vertical slot and a rod extending across said slot, and said means of said first end of said hook member extends into said slot and engages said rod.
Claim 4
Dependent Claim 42 words
A device as claimed in claim 2, wherein said means of said first end of said hook member comprises a hook which engages said rod from the bottom thereof, and said hook has an undercut recess to receive and retain said rod.
Claim 5
Dependent Claim 20 words
A device as claimed in claim 2, wherein said first end of said hook member fits snugly within said slot.
Claim 6
Dependent Claim 61 words
A device as claimed in claim 1, wherein said horizontal adjusting means comprises a side adjustment screw extending parallel to said axis, said side adjustment screw including a portion threaded into said hook member and a portion abutting said fastening element, such that rotation of said side adjustment screw causes movement of said hook member laterally relative to said fastening element.
Claim 7
Dependent Claim 45 words
A device as claimed in claim 1, wherein said vertical adjusting means comprises an eccentric rotatably mounted on said hook member and abutting a horizontal abutment of said fastening element, such that rotation of said eccentric causes said hook member to pivot about said axis.
Claim 8
Dependent Claim 20 words
A device as claimed in claim 6, wherein said eccentric is positioned between said axis and said horizontal adjusting means.
Claim 9
Dependent Claim 80 words
A device as claimed in claim 1, wherein said shifting means comprises a clamping screw threaded into said second end of said hook member and extending through an elongated hole in said fastening element, said clamping screw having an inclined countersunk head engaging a portion of the rim of said hole, such that tightening of said clamping screw causes said inclined head to move along said rim portion, thereby shifting said clamping screw and said hook member in said direction.
Claim 10
Dependent Claim 26 words
A device as claimed in claim 1, wherein said fastening element includes flanges extending parallel to the front panel and against which said holding element abuts.
Claim 11
Dependent Claim 18 words
A device as claimed in claim 1, wherein said fastening element is welded to the drawer side wall.
