Abstract

Abstract A shelf bracket, particularly adapted for mounting on railings and the like, comprises a mounting bracket formed in a generally inverted U-shape with first and second legs depending from ends of a transverse segment. An elongate rigid shelf supporting member is fixed to lower regions of the first leg, below the lower end of the shorter second leg, to project orthogonally outwardly away from the second leg. A thumbscrew is installed in the first leg, below the shelf supporting member for engaging a railing support and enabling leveling of a shelf supported by two or more brackets below the level of the railing. A second thumbscrew is provided in the second leg, relatively close to the transverse segment, for adapting the bracket to railings more narrow than the length of the transverse segment and for clamping the bracket to the railing. Locking nuts are provided for each thumbscrew to maintain the adjustments. An elastomeric "O" ring is installed over the projecting end of the shelf supporting member to prevent a shelf installed on the member from slipping off the end thereof.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 215 words
A shelf support bracket for mounting onto railings or the like, which comprises: a. a one piece railing attaching member formed in a general inverted U-shape adapted for fitting downwardly over a railing or the like and including first and second rigid legs of unequal lengths from a rigid transverse segment, said first leg being substantially shorter than said second leg, said second leg having mounted thereto rail clamping means adapted both for accommodating the member to railings narrower than the length of the transverse segment and for clamping the member to the railing. b. an elongate rigid shelf supporting member fixed to said first leg below the lower end of the second leg and projecting generally perpendicularly therto and away from the second leg, c. adjusting means mounted on the first leg for enabling leveling of the shelf supporting member, said adjusting means including a manually movable element having an inner end portion adapted to engage a member or surface supporting the railing upon which the bracket is mounted, and d. shelf stop including an elastomeric ring slidingly installed over said shelf supporting member and positioned to engage an outer edge of a shelf supported by the bracket, positioning of the ring on the shelf supporting member corresponding to the width of the shelf.
Claim 2
Dependent Claim 215 words
A shelf support bracket for mounting onto railings or the like, which comprises: a. a one piece railing attaching member formed in a general inverted U-shape adapted for fitting downwardly over a railing or the like and including first and second rigid legs of unequal lengths from a rigid transverse segment, said first leg being substantially shorter than said second leg, said second leg having mounted thereto rail clamping means adapted both for accommodating the member to railings narrower than the length of the transverse segment and for clamping the member to the railing. b. an elongate rigid shelf supporting member fixed to said first leg below the lower end of the second leg and projecting generally perpendicularly therto and away from the second leg, c. adjusting means mounted on the first leg for enabling leveling of the shelf supporting member, said adjusting means including a manually movable element having an inner end portion adapted to engage a member or surface supporting the railing upon which the bracket is mounted, and d. shelf stop including an elastomeric ring slidingly installed over said shelf supporting member and positioned to engage an outer edge of a shelf supported by the bracket, positioning of the ring on the shelf supporting member corresponding to the width of the shelf.
Claim 3
Dependent Claim 78 words
The bracket according to claim 1, wherein the rail clamping means includes a threaded element installed orthogonally through the second leg, said threaded element having an inner, railing engaging end and an outer end portion adapted for manually turning to advance or retract the element as necessary to adapt the bracket to a particular railing thickness, and including a locking nut installed over the threaded element for locking the element to the second leg in an adjusted position.
Claim 4
Dependent Claim 104 words
The bracket according to claim 1, wherein the adjusting means movable element is externally threaded and is received in a threaded aperture formed through the first leg, said movable element having an outer end portion adapted for manually turning the element to advance or retract the element as required to level the shelf supporting arm, and including a locking nut for locking the movable element to first leg in an adjusted position, an inner end portion of the movable element including means adapted for fitting around portions of a member supporting the railing upon which the bracket is mounted to thereby assure engagement therewith.
Claim 5
Dependent Claim 73 words
The bracket according to claim 1, wherein the shelf supporting member is rectangular in cross section, the member being fixed to the first leg with a major axis parallel to a longitudinal axis through the first leg and wherein the first leg is formed substantially longer than the second leg and the rail supporting member is fixed to a lower region of the first arm below the lower end of the second leg.
Claim 6
Dependent Claim 59 words
The bracket according to claim 1, wherein the adjusting means movable element and rail clamping means comprise first and second elongate thumbscrews, respectively, said first and second thumbscrews being threaded orthogonally through apertures formed in the first and second legs, respectively, and including locking nuts installed on the thumbscrews for locking the thumbscrews in an adjusted and clamping position.
