Abstract: A staple includes a length of metal wire shaped to form a crown and two spikes. Each spike depends from a respective end of the crown and includes a shoulder at each end of the crown, a sharpened tip portion and an elbow interposed between each tip portion and shoulder, the elbow comprised of a proximal limb and a distal limb such that the tip portions depend from respective distal limbs. An included angle between each shoulder and the crown is between about 91° and 96°, an included angle between each proximal limb and the crown is between about 60° and 85° and an included angle between each distal limb and the crown is between about 95° and 130°.

Abstract: An accessory for a fastening gun includes a magazine assembly with a feed end and a discharge end and configured to support a series of staples in a pre-discharge orientation and with a feed mechanism for feeding the staples from the feed end to the discharge end. A drive member guide assembly is mounted on the magazine assembly and is configured so that a staple drive member can be mounted in the drive member guide assembly and can be driven and retracted along a predetermined path with respect to the magazine assembly, so that, when driven, the drive member can engage a staple to drive legs of the staple into respective components, the drive member guide assembly being configured for mounting on the fastening gun with the drive member connected to a piston or the like of the fastening gun.

Abstract: A U-shaped connector (10) for connecting together abutting or adjoining timber elements includes a stem portion extending between two kinked spike portions (14,16) with each spike portion (14,16) extending in a common direction from the stem portion. Each kinked spike portion (14,16) is comprised of four straight portions (15,18,20,22 and 17,19,21,23) of equal length joined end-to-end, with each straight portion extending at an angle to its adjacent portion. Distal ends (24,25) of each tip portion (22,23) are sharpened and splayed wider than the stem portion. On installation, the flexibility of connector (10) is sufficient to provide a compressive force to the abutting faces of the timbers being joined with the kinked spike portions (14,16) moving outwards away from each other so as to increase the connector's pull out resistance.
