A respective anchor assembly 10 extends through the mounting apertures 202 for mounting the panel 200 to the structure 300. 5 The anchor assembly 10 comprises a base bolt 12, a base body 14, a mount body 16, a ring seal 18, a washer bush 20, mount bolt 22, a front washer 24 and a front cap 26. The base bolt 12 is a 10 mm or 12 mm diameter steel externally threaded bolt which is 100 mm long. As described below, the base bolt 12 is used as an anchor means for mounting the base body 12 to the structure 300. 0 The base body 14 as further shown in Figure 3 comprises a generally cylindrical base body 30 having a rear end 31 and a front end 37. The rear end 31 comprises a planar annular base rear portion 32 which defines a central opening 33 and a peripheral edge 34. A central tubular base formation 36 extends from the central opening 33 of the rear portion 32, and a peripheral base tube 40 extends from the peripheral edge 34 of the rear portion 32. The 5 base formation 36 and base tube 40 are generally parallel to each other, with the base tube 40 extending further from the rear portion 32 than the base formation 36. An annular space 49 is defined between the base formation 36 and the base tube 40, the space 49 extending from the front end 37. The base tube 40 comprises an internal wall 53 and a distal end 55. The base formation 36 comprises an external thread 41 accessible via the annular space 49, .0 an internal thread 45 accessible via the central opening 33, and a front portion 42 facing the front end 37 having a tool engageable screw drive opening 44 formed therein. The screw drive opening 44 in the embodiment is a hex key (Allen key) engageable base drive opening 44 accessible from the front end 37. The rear portion 32 comprises an annular recess 46 formed therein adjacent its junction with the base formation 36. 25 The mount body 16 as further shown in Figure 4 also comprises a generally cylindrical mount body 60 having a rear end 61 and a front end 67. The front end 67 comprises a planar mount front portion 62 having a central aperture 63. A central tubular mount formation 66 extends forwardly from the front portion 62, the mount formation 66 having a central opening 65. The mount formation 66 comprises an internal thread 69. The central aperture 30 63 comprises a tool engageable screw drive opening 64 formed therein, being a hex key engageable mount drive opening 64 accessible through the central opening 65.

The mount tube 70 comprises a central opening 79, an internal thread 77 and an 6 external annular seal seat 76 formed at an external wall 73 thereof, the seat 76 being spaced from the rear end 61. The external wall 73 further comprises a mark indicator 81 therein formed between the seal seat 76 and the flange 71. The use of the indicator 81 is described below. 5 As shown in Figure 5, the mount tube 70 is dimensioned to be received within the annular space 49 of the base body 14, with the internal thread 77 of the mount tube 70 engaging the external thread 41 of the base formation 36. In this position, the external wall 73 of the mount tube 70 is adjacent the internal wall 53 of the base tube 40. The ring seal 18, typically made from rubber and disposed within the seal seat 76, engages the internal wall 53 to form 0 a friction fit between the mount tube 70 and the base tube 40. The peripheral flange 71 is aligned with the base tube 40. Rotation of the mount body 16 relative to the base body 14 thus adjusts the distance between the base rear portion 32 and the mount front portion 62 via the engaging threads 77 and 41. Rotation of the mount body 16 in use can be performed by hand or via a hex key 5 engaging the mount drive opening 64 inserted through the central opening 65 of the mount formation 66. Referring back to Figure 2, the washer bush 20 comprises a tubular portion 90 having a central aperture 91, and a planar annular disc portion 92 extending from an end of the tubular portion 90 and perpendicularly thereto. The disc portion 92 is dimensioned to cover .0 the mount front portion 62 with the tubular portion 90 extending around the mount formation 66. The washer bush 20 is made from plastics material. The mount bolt 22 is a 10 mm or 12 mm diameter stainless steel threaded bolt which is 25 mm long. The front washer 24 comprises an annular disc body 95 having a central aperture 96. The 25 front cap 26 comprises a disc body 100 having a front face 102 and a rear face 104. An attachment tube 106 extends rearwardly from the rear face 104, the attachment tube 106 comprising an internal thread 108. The front face 102 comprises an engagement formation 110 which in the embodiment are spanner head ('snake eye') apertures. The base bolt 12 is dimensioned to threadably engage the internal thread 45 of the base 30 formation 36. The mount bolt 22 is dimensioned to threadably engage the internal thread 69 of the mount formation 66. The attachment tube 106 can be inserted through the aperture 96 of the front washer 24, and the attachment tube 106 is dimensioned to threadably engage the mount bolt 22.

7 Mounting and use of the anchor assembly 10 will now be described with reference to Figures 1 and 2. The base bolt 12 is initially anchored into the structure 300 by drilling an elongated hole into the slab 300 and then a chemical anchoring agent such as epoxy is injected into the hole. The base bolt 12 is then inserted into the hole with a 10 to 15 mm section of the 5 base bolt 12 extending outwardly from the front face 302 of the structure 300. After the epoxy sets, the base bolt 12 is held securely in the structure 300. The base body 14 is threadably attached over the extending section of the base bolt 12 via the internal thread 45 of the base formation 36. The annular recess 46 in the rear portion 32 receives any excess anchoring agent that may seep out around the base bolt 12 to ensure 0 the rear portion 32 is mounted flush to the structure front face 302. If the structure 300 is timber, a lag screw is used instead of the base bolt 12. In such an application, a pilot hole is drilled into the timber structure and the lag screw is threadably attached to the base body 14 via the internal thread 45 of the base formation 36. A hex key bit mounted to a power drill then engages the base drive opening 44 to screw the lag screw 5 into the timber structure until the rear portion 32 is mounted flush to the structure front face 302. The mount body 16 is then attached to the base body 14 as above, by the mount tube 70 being received within the annular space 49 of the base body 14, with the internal thread 77 of the mount tube 70 engaging the external thread 41 of the base formation 36. .0 Rotation of the mount body 16 relative to the base body 14 adjusts the distance between the base rear portion 32 and the mount front portion 62. The mount body 16 can be configured relative to the base body 14 between a fully retracted position as shown in Figure 5 and Figure 1(b), and a fully extended position as shown in Figure 1(a). In the fully retracted position, the distal end 55 of the base tube 40 is adjacent the peripheral flange 71. In the 25 fully extended position, the mark indicator 81 on the external wall 73 of the mount tube 70 is exposed from the distal end 55. The distance between the base rear portion 32 and the mount front portion 62 is about 40 mm in the fully retracted and about 50 mm in the fully extended position. The mount body 16 is attached to the base body 14 with the washer bush 20 already 30 mounted thereto. The tubular portion 90 of the washer bush 20 and the mount formation 66 are then inserted into a mounting aperture 202 of the panel 200, which supports the panel 200 thereon during installation. A lock sub-assembly 29 is then formed with the mount bolt 22 inserted into the attachment tube 106 of the front cap 26 and the front washer 24 placed onto the rear surface 104 of the 35 front cap 26 with the attachment tube 106 inserted through the central aperture 96. The 8 mount bolt 22 is then inserted into the internal thread 69 of the mount formation 66, and tightened thereon via the engagement formation 110 of the front cap 26, to lock the panel 200 to the anchor assembly 10. The panel 200 comprises a number of spaced mounting apertures 202 and a plurality of 5 anchor assemblies 10 are used to mount the panel 200 to the structure 300. The mount front portions 62 of the anchor assemblies 10 are initially aligned using a string line or laser alignment tool prior to mounting the panel 200 to the anchor assemblies 10. Rotation of the mount bodies 16 relative to their base body 14 allows for this alignment. The ring seal 18 provides a friction fit between the mount tube 70 and the base tube 40 to allow finer 0 adjustment and less chance of knocking the anchor assemblies 10 out of adjustment when setting their depth prior to installing the glass panel 200. As shown in Figure 6(b), if further adjustment is required once the panel 200 is mounted to the tubular portion 90 and the mount formation 66, the lock sub-assembly 29 is removed and rotation of the mount body 16 can be performed by a hex key 400 engaging the mount drive 5 opening 64 inserted through the mount aperture 202 and central opening 65 of the mount formation 66. The present embodiment thus provides an anchor assembly 10 for mounting a member 200 at an offset distance to a structure 300, the assembly 10 comprising adjustment means (64, 77, 41) for adjusting the offset distance as desired, the adjustment means being accessible .0 from adjacent an outer surface 204 of the member 200 distal to the structure. The preferred embodiment thus provides an anchor assembly with a number of advantages including: * a recess 46 in the base body for any excess chemical anchoring agent that may seep out around the base bolt used in a concrete structure to ensure the base 25 body sits flush against the structure . * the base body includes a drive opening 44 engageable by a hex key to tighten the base body against the structure. This is very handy when a lag screw needs to screwed into a pilot hole of a timber beam structure. * the mount body is adjustable to allow a clearance of 40-50 mm from the structure 30 to the rear surface 206 of the glass panel and this can be adjustably done without seeing any exposed thread. * the adjustable threaded attachment between the mount body and the base body is covered by the mount tube 40 and the base tube 70 which provides a neat attractive appearance.

9 * a mark indicator 81 on the mount body to indicate you have reached the maximum 50 mm clearance * an O-Ring seal 18 on the mount body creates friction between it and the base body to allow finer adjustment and less chance of knocking the anchors out of 5 adjustment when setting their depth prior to installing the glass panels. The seal 18 also substantially seals the junction between the bodies 14 and 16 against moisture and other foreign particles. * the formation 66 in the face of the mount body in conjunction with the washer bush 20 is designed to support the weight of the glass panel while screwing the cap lock 0 sub-assembly 29 in place. * the mount body includes a drive opening 64 where an Allen Key can be used to adjust the mount body in and out prior to installation of the glass panels and also for alignment and level adjustment of the glass panels from the outside after they have been installed. The installer thus does not have to access the space between 5 the structure and the panel to provide this adjustment, in contrast to the prior art. This Allen Key opening is smaller than that on the base body so that there is no interference. * the front cap 26 can be provided with a choice of shapes and finishes depending on preference of the installed finish, including a bevelled cap with snake eye holes .0 for tightening, a square edge cap with C spanner hole in the side for tightening, or a square edge cap with M10 or M12 countersunk machine screw to be tightened with an Allen Key. Whilst preferred embodiments of the present invention have been described, it will be apparent to skilled persons that modifications can be made to the embodiments described. 25 For example, the drive openings can be shaped in other shapes as desired, including Phillips head or slot shaped screwdriver openings. The adjustment between the base body and the mount body can be modified, and can for example comprise a lockable cam arrangement or a telescopic arrangement therebetween. The mount body in the embodiment is adjustable to allow a clearance of 40 to 50 mm from 30 the structure to the panel, but can be modified to provide any desired clearance range such as between 30 to 60 mm. The assembly has been described herein as being for mounting a panel, but can also be used for mounting other members to a structure such as a post, beam or railing. The 10 structure referred to herein can also be movable structure items such as movable frames, furniture or any other base structure as desired.
