Abstract
Abstract A novel shelf support system which is capable of bearing heavy loads and provides a large measure of adjustability, yet is completely self-contained and only very minimally visible where the shelf meets the wall. The system comprises threaded fasteners for securement to a wall, e.g. at the stud locations, each fastener bearing a support shaft and a spring clip for interengagement with detent grooves which run lengthwise of elongated recessed chambers within the shelf.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
108 words
A wall mounting system for an elongated member with at least one hollow interior chamber having an opening on the side abutting a wall, said opening extending lengthwise of the elongated member, a detent means within the chamber running substantially lengthwise thereof, at least one elongated fastener member having on one end means for rigid securement to the wall and the other end projecting perpendicularly from the wall and spring means associated with said portion of said fastener extending perpendicularly from the wall, said spring means comprising a releasable locking portion biased radially outwardly from the fastener for interengagement with said detent means at selected positions lengthwise thereof.
Claim 2
Dependent Claim
108 words
A wall mounting system for an elongated member with at least one hollow interior chamber having an opening on the side abutting a wall, said opening extending lengthwise of the elongated member, a detent means within the chamber running substantially lengthwise thereof, at least one elongated fastener member having on one end means for rigid securement to the wall and the other end projecting perpendicularly from the wall and spring means associated with said portion of said fastener extending perpendicularly from the wall, said spring means comprising a releasable locking portion biased radially outwardly from the fastener for interengagement with said detent means at selected positions lengthwise thereof.
Claim 3
Dependent Claim
69 words
A mounting system according to claim 1 wherein said detent means comprises at least one elongated groove running lengthwise of said chamber and parallel to the wall, wherein said spring means comprises a leaf spring connected to said elongated fastener member and having a projection biased outwardly from the fastener member and dimensioned to fit within a groove of said detent means to hold the member in locked position.
Claim 4
Dependent Claim
69 words
A mounting system according to claim 1 wherein said detent means comprises at least one elongated groove running lengthwise of said chamber and parallel to the wall, wherein said spring means comprises a spring clip axially mounted on said fastener member and having a projection biased outwardly from the fastener member and dimensioned to fit within a groove of said detent means to hold the shelf in locked position.
Claim 5
Dependent Claim
90 words
A mounting system according to claim 3, wherein said detent means comprises at least one lengthwise groove on each of the upper and lower surfaces of said chamber and wherein said spring clip comprises a pair of V-shaped spring arms mounted at the base of said other end of the fastener member and biased away from the surface thereof, each spring arm having a projection extending outwardly with respect to the fastener member and being adapted to fit within said lengthwise grooves for locking said shelf on said fastener member.
Claim 6
Dependent Claim
44 words
A system according to claim 4 further including openings to the interior of said chamber at ther rear of the upper and lower surface for access to said spring means for movement of the projections on the spring arms out of said detent grooves.
Claim 7
Dependent Claim
27 words
A system according to claim 5 wherein said detent means comprises a plurality of lengthwise grooves on each of the upper and lower surfaces of said chamber.
Claim 8
Dependent Claim
58 words
A system according to claim 1 wherein the end of said elongated fastener member for securement to the wall is provided with threads for fastening said member to a wall and a portion with multiple flattened sides adjacent the threaded portion, said flattened sides adapted to receive wrench means used to secure the threaded portion to the wall.
Claim 9
Dependent Claim
32 words
A system according to claim 2 further including an opening to the interior of said chamber for access to said leaf spring for movement of the projection out of said detent groove.
