CROSS REFERENCE TO RELATED APPLICATIONS

The present application is a U.S. national stage application of PCT International Application No. PCT/AU2019/050236, filed Mar. 15, 2019, and published as PCT Publication WO/2019/173881 on Sep. 19, 2019, which claims priority to Australian Application No. AU 2018900865, filed on Mar. 15, 2018 and to Australian Application No. AU 2018100559, filed on Apr. 30, 2018. The disclosures of all the foregoing applications are hereby incorporated by reference in their entirety into the present application.

FIELD

The invention relates to a frameless glass fencing component, in particular but not exclusively, a frameless glass fencing component for use in installing a frameless glass fence for a swimming pool, balcony, decking or patio.

BACKGROUND

Swimming pool barriers are designed such that young children are unable to climb over them and most countries have strict laws governing what constitutes an acceptable pool barrier. In Australia, for example, all swimming pool barrier fencing must comply with the Australian Standard for Swimming Pool Fencing (AS1926). Some of the stipulations in that standard require that pool fencing be at least 1,200 mm high and that gates be built in such a way that they swing away from the pool and have a child safety lock.

It has become fashionable to provide swimming pool barriers and balcony balustrades in the form of frameless glass fences. Not only is glass durable to the moist environment of a swimming pool, it also provides an aesthetic appealing appearance which is in vogue in contemporary architectural design. A typical frameless glass fence for a pool includes a plurality of individual tempered glass panels which are supported by spaced apart mini-posts, referred to as spigots. Typically, two spigots are evenly spaced across the bottom edge of the glass panel and will clamp onto the panel and support it. Frameless glass fencing spigots must not only be strong to support a glass panel, they must preferably also be corrosion resistant and have favourable aesthetic features. For this reason conventional spigots are produced from anodized aluminium or polished stainless steel.

Frameless glass fencing for balconies, commonly referred to as glass balustrades, typically comprise tempered glass balustrade panels supported by, for example, posts, spigots, standoff fixings, glass clamps or floor glazing channels. Australian Standard AS1170 requires that frameless glass fences be designed to prevent a fall from a balcony. The standard further specifies that (i) the height of the glass fence must be at least 1000 mm when measured from the finished balcony floor level to the top of the balustrade, and (ii) must have a continuous interlinking handrail. Such handrail is required so as to inhibit a fall temporarily in the event of a glass panel of the glass balustrade breaking.

Drawbacks associated with current components employed in supporting glass panels in frameless glass fencing installations include that when they are not maintained or looked after for prolonged periods of time they tend to stain or corrode. In the case of pool fencing, spigots may be installed in a position where they are exposed to electric current and thus capable of conducting electric charge which could lead to a person being subjected to electric shock.

DESCRIPTION OF PREFERRED EMBODIMENTS

Conventional frameless glass fencing components are produced from stainless steel or anodised aluminium. Drawbacks of employing such materials include relative high weight and costs. Further drawbacks associated with stainless steel products include that they tend to stain and corrode over a short or prolonged period of time. Preferred embodiments of the present invention address those problems by doing away with stainless steel/aluminium and providing frameless glass fencing components produced from an engineering plastic. Engineering plastics are plastic materials that are used in applications generally requiring higher performance in the areas of mechanical properties, heat resistance, chemical resistance, impact and fire retardancy. Also, as plastic generally does not conduct electricity, this feature will provide enhanced safety in a moist environment, such as a swimming pool. In particular the preferred engineering plastic will meet the requirements of AS3000:2007 for earth bonding where frameless glass fencing spigots are within arm's reach or up to 1.25 m from the water's edge of a swimming pool.

To provide an aesthetically pleasing appearance the engineering plastic may include an outer coating having a stainless steel appearance. Such coating may be available in a range of colours. Typically, coatings can be applied after surface activation of the engineering plastic product by either plasma, chemical-based materials or spray coatings. Final coatings can then be applied by electroplating, plasma surface coating, powder-coating, PVD coating or spray coating.

A typical embodiment engineering plastic includes a base material having a filler to provide added strength/reinforcing. In an embodiment frameless glass fencing component the filler includes glass fibre. In another embodiment frameless glass fencing component the filler includes carbon fibre.

In an embodiment frameless glass fencing component the base material includes a polyamide. Typical examples of polyamide which could be employed include those sold under the trade marks Nylon® and Zytel®.

In an alternative embodiment the base material of the engineering plastic includes polyphenylene sulfide (PPS). In yet a further alternative the base material of the engineering plastic includes styrene.

FIGS. 1 and 2 show a first embodiment frameless glass fencing component, here a frameless glass fencing spigot generally indicated with the reference numeral 10. The spigot 10 includes a post portion 12 and an attachment formation, here in the form of a flange portion 14. The post portion 12 and flange portion 14 are of unitary construction and produced from an engineering plastic. In this embodiment the engineering plastic is polyarylamide with a 50-60% by volume glass fibre reinforcement concentration. This engineering plastic is a light weight, non-corroding and non-conductive alternative to stainless steel and aluminium. In this embodiment the engineering plastic has an outer coating to provide the appearance of a stainless steel or coloured finish.

The flange portion 14 includes a plurality of fastener openings 16 for receiving non-illustrated fasteners, for example bolts, to secure the post portion 12 in an upright orientation adjacent a pool to be fenced in. The post portion 12 defines a slot 18 for receiving an end portion of a non-illustrated tempered glass panel when constructing a non-illustrated frameless glass fence. The slot 18 includes a polymer packer 20 to protect the glass panel. Typically, the glass panel is secured within the slot 18 with non-illustrated grub screws passing through transverse holes 22 in the post portion 12. In effect a frameless glass fence is constructed in a conventional manner, but with the stainless steel/aluminium spigots replaced with spigots produced from the engineering plastic.

Although not shown in FIGS. 1 and 2, the frameless glass fencing spigot 10 is reinforced with a metal reinforcing member embedded within the engineering plastic and which is over-moulded with the engineering plastic.
