Description
FIELD OF THE INVENTION

The invention relates to a fastener and fastening system. In particular, the invention relates, but is not limited, to fasteners and fastening systems for securing decking boards to joists during deck construction.

BACKGROUND TO THE INVENTION

Reference to background art herein is not to be construed as an admission that such art constitutes common general knowledge in Australia or elsewhere.

Decks are typically constructed of wooden decking boards being affixed to a decking frame which typically includes joists. Various methods of affixing the decking boards are known, the most straight forward being to nail or screw the decking boards to the frame. However, these deck fastening systems all suffer from drawbacks.

For example, nails and screws require the upper surface of the decking board to be penetrated. This can damage the decking board and, in any event, means that unsightly nail or screw heads are visible from the surface of the deck. Moisture also tends to travel through the fastener into the decking board and joist via a capillary action, which can lead to oxidization and rust of the fastener as well as rot and deterioration of the decking board and joist.

Furthermore, vibrations through the decking boards from general use (e.g. people walking on them) can cause the fasteners to unfasten. In this regard, nails often raise out from the boards and screws can unwind. The raised heads of these fasteners are unattractive and can be dangerous. Exacerbating these problems is the fact that as the decking boards weather they can warp, and if the method of affixing is not strong enough the decking boards can lift.

Other decking systems which do not require putting nails or screws through the decking boards are known. One includes a tab or ‘biscuit’ which is received in a groove in the side of the decking boards. The biscuit is fastened to the frame, holding the decking boards to the frame via respective sides received in respective grooves of adjacent decking boards. However, the biscuits are costly and time consuming to install. A separate biscuit is required for each fastening point, and they must be lined up and located in the grooves of the decking boards manually. The additional cost of the biscuits together with the additional labour cost in installing them greatly increases the cost of constructing a deck. Furthermore, to remove a broken or damaged decking board, all the decking boards adjacent to one side of the broken or damaged decking board must be removed. This again is a timely and costly process.

Some other known fastening systems include attaching a perforated strip of angle iron to the side of a joist and fastening the decking boards from the under side with a screw. Another uses screws that are skewed through the edge of the decking boards. However, these are even more difficult and time consuming to use than the previously mentioned biscuit type fasteners.

A further issue with these known fastening systems is that they do not allow for natural movement of the decking boards. The decking boards react to their environment, for example in relation to humidity and dampness (e.g. if they get wet). This causes the boards to move. Known fastening systems prevent, or at least significantly limit, the natural movement of the boards. This places unnecessary strain on both the decking boards and the fasteners, and can even cause damage to either or both of them.

OBJECT OF THE INVENTION

It is an aim of this invention to provide a fastener and fastening system which overcomes or ameliorates one or more of the disadvantages or problems described above, or which at least provides a useful alternative.

Other preferred objects of the present invention will become apparent from the following description.

 DETAILED DESCRIPTION OF THE DRAWINGS

FIG. 1 illustrates a fastener 1010 for fastening decking boards 1020, 1022 to a substantially horizontal upper surface of a joist 30 which would typically form part of a decking frame. Alternatively, the fastener 1010 may be used on other surfaces, such as to fasten the decking boards 1020, 1022 to a concrete pad (not shown).

The fastener 1010, which will be discussed in further detail in relation to FIGS. 2 and 3, has a base 1100 and a plurality of receiving portions 1102 that extend upwards perpendicularly from the base 1100. The receiving portions 1102 are adapted to engage with a receiving portion of the decking boards 1020, 1022. That is, in this embodiment, the receiving portions 1102 include engagement portions in the form of wedge portions 1103. The wedge portions 1103 engage with the receiving portion of the decking boards 1020, 1022 via grooves 1020′, 1022′, which are located in the sides of decking boards 1020, 1022. The shape of grooves 1020′, 1022′ corresponds to the shape of the wedge portions 1103.

Although the engagement portions and grooves 1020′, 1022′ are wedge-shaped in this embodiment, it would be appreciated by a person skilled in the art that the engagement portions and the corresponding shaped grooves 1020′, 1022′ may take a variety of shapes. Advantages of the wedge-shape in this embodiment however, include that it allows boards to be inserted and removed relatively easy from the fastener 1010. Furthermore, this wedge-shape is relatively easy to manufacture.

The base 1100 is affixed to the joist 30 by screws (not shown) which are received in recessed portions 1101 of the base 1100. The base 1100 may be provided with both wood screw recesses 1101a and masonry anchor recesses 1101b, with the masonry anchor recesses 1101b being generally larger. The recessed portions 1101 have a weakened portion which is punctured by the fastener being used. A seal is substantially maintained between the base and the joist 30 when the fastener is punctured through the recessed portions 1101. In addition, the recessed portions 1101 allow the fastener to be countersunk, and as such, the head of the fastener do not protrude beyond an upper face of the base 1100.

Each receiving portion 1102 is, in use, located between two decking boards (e.g. 1020, 1022) and, therefore, is typically not visible in use. FIG. 1 illustrates an exposed portion of the fastener 1010 where the receiving portion 1102 is visible adjacent a single decking board 1020.

While FIG. 2 illustrates a single receiving portion 1102, it will be appreciated that in preferred embodiments the base 1100 is elongate with a plurality of receiving portions 1102 arranged to facilitate fastening of many decking boards to the joist 30 at once.

In FIG. 2, the receiving portion 1102 is more clearly seen to extend perpendicularly to the base 1100. Furthermore, the receiving portion 1102 is aligned substantially parallel with the longitudinal direction of the decking boards, when in use. The receiving portion 1102 includes an opening 1104. The opening 1104 extends through the receiving portion 1102 (i.e. the opening 1104 extends through the receiving portion 1102 in the longitudinal direction of the decking boards, when in use). Wedge portions 1103 are either side of the opening 1104. In this embodiment, the opening 1104 includes two walls that are tapered towards the base 1100. The two walls have a gripping surface in the form of sawtooth portions. The two walls, and as such, the wedge portions 1103 are able to pivot around a lower portion of the opening 1104.

Each receiving portion 1102 of the fastener also has a locking member 1120. The locking member 1120 has a longitudinal head portion 1122 and a locking portion 1124. In this embodiment, the locking portion 1124 has two tapered sides. The tapered sides of the locking portion 1124 have a gripping surface in the form of sawtooth portions which engage with corresponding sawtooth portions inside the opening 1104.

Due to the shape of the sawtooth portions, the locking portion 1124 of the locking member 1120 is relatively easy to press into the opening 1104 of the receiving portion 1102 but are relatively difficult to be removed in the opposite direction. However, the locking member 1120 may be removed from the receiving portion 1102, if needed, by sliding the locking member 1120 out of the opening 1104 in the longitudinal direction of the decking boards, when in use.

Turning to FIG. 3, a cross section of the fastener 1010 in use between two decking boards 1020 and 1022 is illustrated. Although not shown, the base 1100 is affixed to a substantially horizontal surface, such as a joist 30 as shown in FIG. 1. The decking boards 1020, 1022 are then located on top of the base 1100 adjacent opposite sides of the receiving portion 1102 of the base 1100. As such, the wedge portions 1103 of the receiving portion 1102 are received into the grooves 1020′, 1022′ of the two decking boards 1020 and 1022, respectively.

The locking member 1120 is located securely in the receiving portion 1102 of the base 1100 with the corresponding sawtooth surfaces gripping against each other. When the locking member 1120 is inserted into the opening 1104, it drives the wedge portions 1103 to pivot outwardly about the lower portion of the opening 1104. As the wedge portions 1103 pivot, they are further received into grooves 1020′, 1022′ of the decking boards 1020, 1022.

When the locking member 1120 is securely located in the receiving portion 1102 of the base 1100, the rigid engagement between the wedge portions 1103 and wedge-shaped grooves 1020′, 1022′ substantially prevents the decking boards 1020, 1022 being removed from the fastener 1010. For example, if the decking boards 1020, 1022 lift perpendicularly to the base 1100, the wedge portions 1103 and wedge-shaped grooves 1020′, 1022′ will bear upon one another and resist such movement. Accordingly, as the locking member 1120 prevents the opening 1104 from closing, the decking board 1020, 1022 are prevented from being leveraged past the wedge portions 1103.

As shown in FIGS. 1 and 2, the base 1100 has wings 1108 which are angled downwards. The wings 1108 are spaced apart by the width of the joist 30 and provide additional protection to the joist 30 from above. The wings 1108 are removable, by tearing, from the base 1100 where they are not required. The wings 1108 are tearable by having a weakened portion in the form of a groove 1108′, as shown in FIG. 2. For example, the wings 1108 are typically not required when the fastener 1010 is used on a concrete pad or other substantially level planar surface (not shown). The wings 1108 can therefore be removed from the base 1100 during the installation of the decking fixing system prior to fitting the decking boards.

In alternative or additional embodiment, the wings 1108 may be sufficiently flexible. As such, the wings 1108 can be laid flat if desired. Accordingly, in this embodiment, the wings 1108 may not have to be removed if the fastener 1010 is required to be used on a concrete pad. That is, the wings 1108 will flex to be substantially flat on the concrete pad.

The base 1100 also features a tongue portion 1105 at one end of the base 1100 and a seat portion 1106 at the other end of the base 1100. The tongue portion 1105 and the seat portion 1106 both feature a recessed portion. The tongue portion 1105 or seat portion 1106 are used to connect the base 1100 to a further base. When the tongue or seat portions 1105, 1106 of respective bases are overlapped, the bases remain substantially flat and the recessed portions align. Accordingly, to connect the base 1100 to a further base, a fastener is driven through the substantially aligned recessed portions into the joist 30.

A deck is built using the fastener 1010 by first affixing the base 1100 to a substantially horizontal surface, such as a joist 30 as shown in FIG. 1. A decking board 1020, 1022 is then located on the base 1100 between two receiving portions 1102 of the base 1100, or where the decking board is at an end of the base 1100, adjacent the endmost receiving portion 1102 of the base 1100. When the next decking board 1020, 1022 is located adjacent the existing decking board 1020, 1022, via grooves 1020′, 1022′, the locking member 1120 is then located in the opening 1104 and forced downwards, typically with a tool, such that the locking portion 1124 of the locking member 1120 travels further into the opening 1104. The decking boards 1020, 1022 are then unable to be lifted from the joist 30 as they are held down by the wedge portions 1103 which have pivoted towards the walls of the wedge-shaped grooves 1020′, 1022′. This process is continued to fasten further decking boards to the joist 30.

FIG. 4 illustrates an alternative fastener 10 for fastening decking boards 20, 22 to a substantially horizontal upper surface of a joist 30.

The fastener 10, which will be discussed in further detail in relation to FIGS. 5 and 6, has a portion received in standard square shaped grooves 20′, 22′ in the sides of decking boards 20, 22. Similar to fastener 1010, the fastener 10 has a base 100 and a plurality of receiving portions 102 that extend upwards perpendicularly from the base 100. The base 100 is affixed to the joist 30 by screws (not shown) which are received in recessed portions (not shown) of the base 100. FIG. 4 illustrates an exposed portion of the fastener 10 where the receiving portion 102 is visible adjacent a single decking board 20.

Turning to the single interlocking portion of fastener 10 shown in FIG. 5, the receiving portion 102 is more clearly seen to extend perpendicularly to the base 100 and is aligned substantially parallel with the longitudinal direction of the decking boards, when in use. The receiving portion 102 has a plurality of slots 104 separated by ribs 106. The ribs 106 provide additional support and strength to the slots 104, preventing any deformation of the receiving portion 102 when in use.

Each receiving portion 102 of the fastener also has an interlocking member 110 and a locking member 120. The interlocking member 110 has an aperture 112 corresponding to each slot 104. The apertures 112 are the same width as the slots 104 but are longer than the slots 104, and are offset. This allows the apertures 112 to be located over the slots 104 when the interlocking member 110 is moved laterally (i.e. perpendicular to the longitudinal axis of the decking boards, when in use).

The locking member 120 has a longitudinal head portion 122 and a plurality of fingers 124. The fingers 124 are arranged such that they are received by, and pass through, the apertures 112 of the interlocking member 120 and then are received by the slots 104 of the receiving portion 102 of the base 100. The fingers 124 have a gripping surface in the form of sawtooth portions on each side which engage with corresponding sawtooth portions inside the slots 104 (not shown in FIG. 5, see FIG. 6).

Similar to fastener 1010, due to the shape of the sawtooth portions, the fingers 124 of the locking member 120 are relatively easy to press into the slots 104 of the receiving portion 102 of the base 100 but are relatively difficult to be removed. However, unlike fastener 1010, the locking member 120 cannot be removed by sliding the locking member 120 in the longitudinal direction of the decking boards. That is, once constructed, with a decking board 20, 22 located on either side of the receiving portion 102, the fingers 124 of the locking member 120 are held securely in the slots 104 of the receiving portion 102 of the base 100.

Turning to FIG. 6, a cross section of the fastener 10 in use between two decking boards 20 and 22 is illustrated. The interlocking member 110 is received in grooves 20′, 22′ of the decking boards 20, 22 and is held in place between the locking member 120 and the receiving portion 102 of the base 100 by the fingers 124 of the locking member 120. The fingers 124 are located securely in the receiving portion 102 of the base 100 with the corresponding sawtooth surfaces gripping against each other to lock the locking member 120 in place. The ribs 106 (shown in FIG. 5) between slots 104 of the receiving portion 102 provide support to the sides of the slots and prevent the slots 104 from deforming which may release the fingers 124.

Additionally, when in use as illustrated in FIG. 6, the decking boards 20, 22 can provide additional support (albeit minor) to the outer sides of the receiving portion 102 further preventing the slots 104 from deforming. However, this additional support is relatively minor as it is preferred that there is a small gap between the edges of the decking boards 20, 22 and the receiving portion 102 to allow for natural expansion and contraction of the decking boards caused by varying moisture content and temperature.

Similar to fastener 1010, as shown in FIGS. 4 and 5, the base 100 has removable wings 108 which are angled downwards to provide additional protection to the joist 30 from above.

Building a deck with fastener 10 shares a number of similarities with building a deck with fastener 1010. The interlocking member 110 and locking member 120 are loosely located on the receiving portion 102 of the base 100 such that the interlocking member 110 is positioned to one side and can move relatively freely and such that the locking member 120 is not fully located in the receiving portion 102 of the base 100. It is envisaged that the base 100 could be provided with the interlocking member 110 and locking 120 already in this position.

A decking board 20, 22 is then located on the base 100 between two receiving portions 102 of the base 100, or where the decking board is at an end of the base 100, adjacent the endmost receiving portion 102 of the base 100. Where an existing decking board 20, 22 has already been placed the interlocking member 110 that will be located between that existing decking board 20, 22 and the next decking board will be centred relative to the receiving portion 102 of the base 100.

When the next decking board 20, 22 is located on the base 100 its groove adjacent the existing decking board 20, 22 and already centred interlocking member 110 is positioned to receive the free side of the already centred interlocking member such that the interlocking member 110 is centred and located in both grooves 20′, 22′ as shown in FIG. 6. The next interlocking member 110, which is offset (i.e. not centred), is then slid laterally into the groove 20′, 22′ on the other side of the decking board 20, 22.

Once the decking boards 20, 22 are located as desired, the locking member 120 is forced downwards, typically with a tool, such that fingers 124 of the locking member 120 travel further into the slots 104 retaining the locking member 120 therein. The decking boards 20, 22 are then unable to be lifted from the joist 30 as they are held down by their grooves by the interlocking member 110 which is held down by the locking member 120 which is secured to the base 100 via the receiving portion 102. This process is continued to fasten further decking boards to the joist 30.

Further fastener designs 12 and 13 are provided in FIGS. 7 and 8, respectively. Both fastener designs have a base 200, 300 and a protrusion 202, 302. Use of the fasteners 12 and 13 in FIGS. 7 and 8 both require the grooves 20′, 22′ of the decking boards 20, 22 to be shaped, with at least one bevelled edge.

Turning specifically to the fastener design 12 illustrated in FIG. 7, the protrusion 202 has a head 204 that includes flexible portions that allow the head 204 to deform. Gripping portions 206, 208 located inside the head 204 are shaped to grip each other when the head 204 of the protrusion 202 is depressed downwards. This downward action causes outer edges 210 of the head 204 to slide outwards into the grooves 20′, 22′ of the decking boards 20, 20 which retains them in place.

The fastener design 13 in FIG. 8 has no moving parts, but rather requires the grooves 20′, 22′ of the decking boards to be shaped correspondingly to the head 304 of the protrusion 302 and relies on the decking boards being placed against the head 304 at an angle. The head 304 is general frustroconical in cross-sectional shape.

In use, the fastener 1010 provides a quick and easy fastening system to seamlessly build a deck without the need to puncture the decking boards 1020, 1022. The base 1100 and wings 1108 further provide sealing and weatherproofing to the joist 30. Furthermore, the recessed portions 1101 allow the joist 30 to remain substantially weatherproof when fasteners attach the base 1100 to the joist 30. Conveniently, the same base 1100 can also be used to affix decking boards 1020, 1022 to concrete pads.

The fastener 1010 also provides a strong engagement with the decking boards 1020, 1022, while also allowing for some natural movement of the decking boards 1020, 1022. The locking member 1120 is readily located in the opening 1104 of the receiving portion 1102 of the base 1100 and easily locks the assembly together during construction. Similar advantages also apply to the other fastener systems describe herein.

Fastener 1010 also allows individual decking boards 1020, 1022 to be removed from the deck if needed. If an individual decking board is required to be removed, the locking member 1120 is first removed from the receiving portion 1102 by sliding the locking member 1120 out of the opening 1104 in the longitudinal direction of the decking boards. With the locking member 1120 released, the individual decking board can then be leveraged past the wedge portions 1103. That is, as a leverage force is applied to the individual decking board, a force is applied to the wedge portions 1103 which causes the opening 1104 to close and the wedge portions 1103 to pivot out of the way of the individual decking board. As such, the individual decking board can be removed and subsequently replaced. During replacement, the wedge portions 1103 will again pivot out of the way of the new board being inserted into the deck.

In addition, as multiple receiving members 1102 are provided on a single base 1100 it is not necessary to have to locate and fasten numerous individual parts. The decking boards 1020, 1022 are simply placed between the receiving portions 1102 of the base 1100, and locked into place by securing the locking member 120. Furthermore, the locations of the receiving portions 1102 of the base 1100 are used to position and locate the decking boards 1020, 1022 which ensures that they are aligned and located properly. Similar advantages again also apply to the other fastener systems describe herein.

In this specification, adjectives such as first and second, left and right, top and bottom, and the like may be used solely to distinguish one element or action from another element or action without necessarily requiring or implying any actual such relationship or order.
