BRACKETS

Divisional of Australian Patent Application No. 2004 205 156 filed on August 2004 The following statement is a full description of this invention including the best method of performing it known to us:m:\docs\200411 70\099795.doc This invention relates to concreter's scaffolding brackets for use with fences and walls.

According to one aspect of the invention there is provided a scaffolding bracket comprising a planar member being no thicker than the normal spacing between courses of house bricks so that one end of the planar member may be inserted into a brick wall, and wherein the other end of the planar member has a bracket adapted to receive a plank that extends from the scaffolding bracket to an adjacent scaffolding bracket.

The scaffolding bracket of the invention is used with an adjustable bracket to allow a concreter access to newly laid concrete for the application of stencil paper and colour without the need for the concreter to walk across the newly laid concrete where a wall limits access.

The adjustable scaffolding bracket is designed to provide a stable fence bracket which is adjustable in the vertical planes to suit differing fence heights and may be adjustable horizontally at the bracket head to accommodate different fence widths. Once attached to the fence, the bracket provides a support station for mounting a plank of wood or metal for movement parallel to the fence line without the need to walk on the newly prepared concrete surface below.

The scaffolding bracket of the invention is designed to provide a stable wall bracket that fits snugly into weep holes in brickwork or like vents.

Although the invention will be described in relation to scaffolding brackets for use by concreters, it will be apparent that the scaffolding brackets may be used in other circumstances where it is desirable to avoid contact with the surface below.

19/05/06 3 In order that the invention may be more readily understood and put into practical effect, reference will now be made to the accompanying drawings in which:- Fig. 1 is a side perspective view of an adjustable scaffolding bracket suitable for use with the scaffolding bracket of the invention, Fig. 2 is a side perspective view of a scaffolding bracket according to one embodiment of the invention, Fig. 3 is a plan view of the scaffolding bracket shown in Fig. 2, Fig. 4 is an end view of the scaffolding bracket shown in Fig. 2, Fig. 5 is a side view of the scaffolding bracket of Fig. 1 installed on a fence and a scaffolding bracket of Figs. 2 to 4 in place in a brick wall, and Fig. 6 is a perspective view of the installation shown in Fig. The scaffolding bracket 10 shown in Fig. 1 includes a height adjustable upright 11 having an upper end or head 12 and a lower end or foot 13. An upper bracket 14 has a downwardly depending clamp member 18 which abuts against the side of the fence remote from the upright 11. A strengthening strut 23 extends between the upright 11 and the first clamp member 16.

At the lower end 13 of the upright 11, there is a lower bracket 24 which extends in the opposite direction to the upper bracket 14. The lower bracket 24 has a horizontal portion 25, a vertical portion 26 and a strengthening strut 27 therebetween. There is also an upper strengthening strut 28 between the upright 11 and the lower bracket 24. A bracket 29 is adapted to receive a plank as will be described below.

19/05/06 In this instance, the upright 11 comprises a lower tube 30 and an upper tube 31 which slides within the lower tube 30. The lower tube 30 has a locking aperture 32 and the upper tube 31 has an array of locking apertures 33, the arrangement being such that one of the locking apertures in the upper tube is aligned with the locking aperture in the lower tube 30 and is held in place by a locking pin 34 passing through the aligned apertures. The locking pin 34 is attached to a chain The second scaffolding bracket 40 shown in Figs. 2 to 4 comprises a planar member 41 which is no higher than the normal spacing between courses of house bricks so that the planar member may be inserted into weep holes between adjacent bricks in the brickwork.

At one end of the cross piece 42 there is a plank support bracket 43 adapted to receive a plank 44 which extends from the scaffolding bracket 40 to an adjacent similar scaffolding bracket.

As shown in Figs. 5 and 6, the first scaffolding bracket 10 is positioned on a fence 45 with the upper bracket 14 clamped to the upper extremity of the fence 45. The upright portion 26 of the lower bracket 24 abuts against the fence as can be seen on the right hand side of Fig. 4.

The second scaffolding bracket 40 is located in the brickwork 46 and planks 44 installed between adjacent brackets on the fence and on the brick wall. The concreters can then walk along the planks 44 and, for example, lay the stencil paper 47 on the concrete 48.

Various modifications may be made in details of design and construction without departing from the scope and ambit of the invention.

Claims

1. A scaffolding bracket comprising an upright planar member being no higher than the normal spacing between courses of house bricks so that one end of the planar member may be inserted into a brick wall, between adjacent bricks and wherein the other end of the planar member has a plank support bracket adapted to receive a plank that extends from the scaffolding bracket to an adjacent scaffolding bracket.

2. A scaffolding bracket according to claim 1 wherein the plank support bracket includes a planar base and an outer upright portion which when the bracket is in use is parallel to and spaced from the brick wall.

3. A scaffolding bracket according to claim 8 substantially as hereinbefore described with reference to Figures 2 to
