Total Claims: 10
Claim 1
Independent Claim
287 words
A bracket for supporting a shelf or the like from an upright cylindrical support, said bracket comprising an elongate arm upon which a shelf or the like is supported horizontally in use of the bracket and a clamping head arranged at one end of said arm for attaching the bracket to the said upright cylindrical support, wherein said clamping head comprises a part-cylindrical portion attached to said arm and adapted to lie against part of the circumference of the cylindrical support, a leaf spring member permanently having a natural curvature which is substantially the same as that of said part-cylindrical portion, means for permanently attaching one end of said leaf spring member to said part-cylindrical portion forming a substantially continuous internal cylindrical surface which lies against the surface of the cylindrical support in use of the bracket, a part-cylindrical member, means for permanently attaching the part-cylindrical member to the other end of said leaf spring member, said partcylindrical member having a curvature substantially the same as that of said part-cylindrical portion, the natural resilience of said spring strip and the length of the latter being such that when said part-cylindrical portion lies against part of the circumference of the cylindrical support the spring strip brings the part-cylindrical member into juxtaposition with another part of the circumference of said support while the spring strip itself lies against an intermediate part of the circumference of said support so that the head surrounds said support, said partcylindrical member having a straight portion which lies adjacent part of said arm when the leaf spring member embraces the support, and securing means for releasably connecting said straight portion and said adjacent part of the arm to clamp the head to the support.
Claim 2
Dependent Claim
287 words
A bracket for supporting a shelf or the like from an upright cylindrical support, said bracket comprising an elongate arm upon which a shelf or the like is supported horizontally in use of the bracket and a clamping head arranged at one end of said arm for attaching the bracket to the said upright cylindrical support, wherein said clamping head comprises a part-cylindrical portion attached to said arm and adapted to lie against part of the circumference of the cylindrical support, a leaf spring member permanently having a natural curvature which is substantially the same as that of said part-cylindrical portion, means for permanently attaching one end of said leaf spring member to said part-cylindrical portion forming a substantially continuous internal cylindrical surface which lies against the surface of the cylindrical support in use of the bracket, a part-cylindrical member, means for permanently attaching the part-cylindrical member to the other end of said leaf spring member, said partcylindrical member having a curvature substantially the same as that of said part-cylindrical portion, the natural resilience of said spring strip and the length of the latter being such that when said part-cylindrical portion lies against part of the circumference of the cylindrical support the spring strip brings the part-cylindrical member into juxtaposition with another part of the circumference of said support while the spring strip itself lies against an intermediate part of the circumference of said support so that the head surrounds said support, said partcylindrical member having a straight portion which lies adjacent part of said arm when the leaf spring member embraces the support, and securing means for releasably connecting said straight portion and said adjacent part of the arm to clamp the head to the support.
Claim 3
Dependent Claim
48 words
A bracket as claimed in claim 1, wherein said integral part-cylindrical portion and said separate part-cylindrical member each have a length substantially corresponding to a quarter (90*) of the circumference of the cylindrical support, said spring member having a length substantially corresponding to half (180*) of said circumference.
Claim 4
Dependent Claim
30 words
A bracket as claimed in claim 1, wherein said securing means is constituted by at least one screw which is screwable into tapped holes one in each said co-operating portions.
Claim 5
Dependent Claim
61 words
A bracket as claimed in claim 3, wherein said screw has a cylindrical head which at its end remote from the screwthread is provided with a knurled portion and a slot for receiving an operating tool, the other end of the screw head being contiguous with a portion of reduced diameter which is smaller than the diameter of the adjacent screwthread.
Claim 6
Dependent Claim
26 words
A bracket as claimed in claim 1, wherein said spring member is attached to said integral portion and said separate part-cylindrical member by means of riveting.
Claim 7
Dependent Claim
49 words
A bracket as claimed in claim 1, wherein at least one locating hole is provided in one or the other of said co-operating portions which is engageable by a peg in said other or said one co-operating portion for aligning said co-operating portions and for strengthening the connection therebetween.
Claim 8
Dependent Claim
30 words
A bracket as claimed in claim 1 in which the width of the spring strip is greater than the diameter of the cylindrical support to which the bracket is attached.
Claim 9
Dependent Claim
20 words
A bracket as claimed in claim 1 wherein each of said means for permanently attaching comprises a plurality of rivets.
Claim 10
Dependent Claim
51 words
A bracket as claimed in claim 1 wherein said receiving means comprises a screw in one of said arm or straight portion and a tapped hole in the other of said arm or straight portion, whereby said hole and screw are automatically in line when the bracket is about the support.
