Description
Fastening of weatherboards and the like with a powered fastening tool
Field of the invention
The invention generally relates to a system for use with a powered fastener driving tool, and more specifically to a fastener for use with a powered fastener driving tool for fastening flat wooden substrates, a driving blade for use with a powered fastener driving tool and a nose piece for a powered fastener driving tool for contacting a work piece.
Background of the invention
Weatherboard (also known as clapboard) is a type of horizontal or vertical timber board used as a siding for a building. A series of overlapping horizontal weatherboards can be fastened on a wall or roof to provide exterior cladding. It is known to fasten weatherboards with the use of fasteners by hand nailing, including for example rounded off-set nails, because gas powered nailing tools are not adapted or suitable for use with fasteners rated for weatherboard applications due to issues with fastener compatibility and significant damage to weatherboards sustained by the use of conventional gas powered nailing tools in driving fasteners below the surface of the weatherboard.
Conventional methods for fastening weatherboards are time-consuming and laborious.
Typically, weatherboards are marked and pre-drilled before fasteners are hand hammered and then hand punched below the surface of the timber substrate to a depth of about 2 mm. The fastener cavities are then primed and filled before the affected areas are sanded and painted to provide an aesthetic finish.
The applicant has determined that it would be advantageous to provide a system, including a fastener, a driving blade and optionally a nose piece for use with a powered fastener driving tool, which improves the efficiency in the manner in which weatherboards are fastened. The present invention, in its preferred embodiments, seeks to at least in part alleviate the above-identified problems or to provide the public with a useful choice.

Detailed description
The present invention relates to a system, including a fastener 100, a driving blade 200 and optionally a nose piece 300 for use with a powered fastener driving tool (not shown). It is 20 to be understood that a powered fastener driving tool as described in the present invention includes a gas-powered fastener driving tool such as a cordless framing nailer. While components of the system will be described to function together, it is to be understood that each component could be equally suitable for use separately from said system. The present invention further provides for a powered fastener driving tool comprising a driving blade 25 200 and/or a nose piece 300 as to be described.
Referring to Figures 1 to 3, which show non-scaled views of a fastener 100 according to a preferred embodiment of the prevent invention, the fastener 100 is in the form of a nail having a head 110, and a shank 116 extending from the head 110. A support gusset 30 portion is provided between the head 110 and the shank 116. A piercing end 118 is provided at an opposing end of the shank for piercing through a work piece substrate in

-6use. In one embodiment, the shank 116 is positioned off-centre with respect to the head to improve stacking and hence allow a greater number of nails per a length of collated nail strip.
As can be seen from Figures 1 and 2, the head 110 has a generally flat top and can be said to be configured in the form of a substantially circular or round shape. In one configuration, the shank 116 extends relative to the head 110 such that a circumference of the shank 116 is inscribed within a circumference of the head 110. In a further configuration, the shank is additionally located substantially tangential to the 10 circumference of the head such that a heel 115 is defined generally where the head 110 and the shank 116 are collinear as seen in Figure 1. The heel 115 can be configured such that it is a substantially flat portion as seen in Figure 2. In one configuration, the heel 115 is configured with a length of about 2 mm. In some embodiments, the head 110 can be provided with a vertical projection 114 defined along the length of the heel 115.
The dimension of the head 110 is configured such that the diameter of the head 110 is not more than about 5.5 mm. In the preferred embodiment, the diameter of the head 110 is about 5.3 mm. In cases where the fastener head 110 has a substantially flat heel portion 115, the diameter of the head 110 measured directly across from the flat heel portion 115 is 20 about 5.1 mm. Additionally, the head 110 may be configured with a thickness of about
1.25 to about 1.5 mm. It is to be appreciated that the purpose-designed diameter dimensions of the head 110 are specifically configured so that the fastener 100 is well suited for applications including fastening flat wooden substrates such as weatherboards without causing damage to the timber, such as splitting the board upon entry of the 25 fastener 100.
Even though the fastener 100 has been described to be purpose-designed for weatherboard fastening application, it is to be understood that the fastener 100 may also be suitable use in unrelated applications.
Figures 4 to 6 show a driving blade 200 for use with a powered fastener driving tool

-7having an elongated shaft 210 provided with an end 212 to be driven by the tool and a blade head 220 located at the opposing end for striking and/or pushing a fastener 100 as it is dispensed or propelled from the tool into a work substrate during use. The length of the blade head 220 is configured with a reduced width than that of the elongated shaft 210. In some configurations, the width of the blade head 220 is substantially constant along the length of the head. In one embodiment, concave-shaped radial comers 228 are provided at a transition portion along the elongated shaft 210 where width of the blade head 220 is narrowed.
In a preferred embodiment, the blade head 220 is provided with a flat engagement portion 222 for contacting fasteners 100 to be dispensed. In one embodiment, the width of the blade head 220 is configured to correspond substantially with the diameter of the fastener head 110 as previously described so that the driving blade 200 is well suited to drive fasteners 100 as configured for weatherboard fastening application. The reduced width of the blade head 220 and engagement portion 222 advantageously provide improved accuracy for dispensing similarly-sized fasteners 100 while not sacrificing performance or longevity of service. Accordingly, in one configuration, the width of the blade head 220 and the engagement portion 222 is no more than about 5.5 mm.
As can be seen in Figures 5 and 6, the blade head 220 is also provided with a tapered portion 224 on one side of the blade head 220 which extends partially in the longitudinal direction between the elongated shaft 210 and the flat engagement portion 222 so as to reduce the thickness of the blade head 220. The blade head 220 may also be provided with chamfers 226 extending from the tapered portion 224 to the sides of the head 220 to further 25 reduce the thickness of the blade head 220.
In a further embodiment, and with reference to Figure 6, the engagement portion 222 may be configured in the form of a rectangular shape with rounded comers for reducing the driving footprint of the driving blade 200 on fasteners in use. This advantageously reduces 30 any damage to protective layers of the fastener heads 110, such as galvanisation, caused by contact between the engagement portion 222 and the fastener heads 110.

-8Referring to Figures 7 to 9, the nose piece 300 has a body 310 configured for fitting over or latching onto a fastener-dispensing portion of the powered fastener driving tool and an adjustable tool alignment guide 320 which extends sideways from the body 310. The 5 alignment guide 320 serves to guide the positioning of the powered tool relative to a work piece at adjustably fixed intervals/distances prior to driving fasteners - this effectively bypasses the need for pre-marking distances on the work piece for driving the fasteners and therefore creates significant efficiencies for the operator. In one configuration, the alignment guide is provided with an alignment member 324 adapted for abutting a corner 10 portion of a work piece so as to prevent movement of the powered tool in a direction substantially perpendicular to the work piece when in use. In use, an operator abuts the alignment member 324 against a lower or upper edge of a work piece, for example a weatherboard, so that movement of the powered tool is fixed in one direction. The alignment member 324 is configured to be slideably moveable relative to the nose body 15 310 to adjust the distance between the power tool and the point where the alignment member is secured to the work piece to cater for a range of adjustable distances. This feature advantageously provides precise and consistent positioning of the powered tool at fixed distances from an edge of the work piece even as the powered tool is used across a horizontal length of the work piece.
A bracket 322 can be provided for securing the alignment member to the body 310 of the nose piece 300. In one configuration, the alignment member 324 is configured with an 'L' portion for abutting or hooking onto an edge of the work piece. The alignment member 324 is slideable relative to a plate portion of the bracket 322 to adjust the distance between 25 the 'L' portion of the alignment member and the dispensing portion of the powered tool. In one configuration, the alignment member 324 is provided with a groove 326 for which a fastener 328 can be used to adjustably secure the alignment member 324 to the plate portion bracket 322.
In one embodiment, the nose piece 300 may be provided with a stop 332 made from, or coated with, a resilient material extending from the body 310 of the nose piece 300 for
C:\Interwoven\NRPortbl\DCC\EJL\l7162155_ I .docx-15/06/2018
2018204271 15 Jun 2018
-9contacting a work piece in front of the powered tool. The resilient material cushions the contact between the powered tool and the work piece so that marking/damage to the work piece due to recoil when the tool is held against the tool and fired is reduced. The resilient (or non-marking) stop 332 is located in an area of the nose body 310 where substantial 5 force/pressure would be applied from using the powered tool on a work piece so as to reduce any markings or damage to the work piece caused by the firing action of the powered tool. In another embodiment, each part of the nose piece 300 that is to come into contact with the work piece can be covered or coated with a resilient or non-marking material, which could be sourced from any suitable materials such as rubber.
It is to be appreciated that the nose piece 300 for use with a powered fastener driving tool is well-suited for use as part of a system with the fastener 100 and a powered fastener driving tool with the driving blade 200 as described above because the adjustable tool alignment guide is well suited for latching onto an edge of weatherboards and the non15 marking projection helps reduce damage to weatherboards, which typically require an aesthetic finish when used as external cladding. While the nose piece 300 is particularly well-suited for use with powered fastener driving tools for weatherboard applications, it is to be understood that the nose piece 300 may also be equally suited for powered tools used in unrelated applications.
In the description and drawings of this embodiment, same reference numerals are used as have been used in respect of the first embodiment, to denote and refer to corresponding features.
While various embodiments of the present invention have been described above, it should be understood that they have been presented by way of example only, and not by way of limitation. It will be apparent to a person skilled in the relevant art that various changes in form and detail can be made therein without departing from the spirit and scope of the invention. Thus, the present invention should not be limited by any of the above described 30 exemplary embodiments.
