FASTENING SYSTEM FOR DECKING BOARDS
A fastening system for decking boards (16) includes a series of supports (14) that define a central raised wall (24) and two planar portions (22) located either side of the wall. A stem (52) depending from a generally semi-circular washer (18) extends into a recess in the wall. Slots in the decking board run along both sides of the board. A first pair of supports is located on a bearer (12) and a first board is supported on the planar portions (22) of the supports, above the bearer. One half of the semi-circular top (50) of one washer is rotated to extend into the slot in the side of the decking board. A second board is located adjacent the first board on the support. A further support is slipped under the side of the second board. A washer in the further support is rotated and locked in place with a screw.
This application claims priority from Australia provisional patent application No AU 2015902259 filed in the name of Elmich Pte Ltd entitled “Fastening system for decking boards” the entire contents of which are incorporated herein by reference.
TECHNICAL FIELDThis invention relates to a fastening system for decking boards/floor boards.
BACKGROUNDDecking boards have been used extensively to create raised decks and floors. Decking boards are laid side by side, spaced apart by about 5 mm on top of transverse bearers, and are fixed to the bearers using nails.
One problem with current methods for laying decking boards occurs when it is necessary to remove the decking boards, either to replace damaged decking boards, or for access underneath the deck for services or the like. This is difficult to do as it involves removal of a number of boards and the removal of the boards often results in damage to the deck.
Any discussion of documents, acts, materials, devices, articles or the like which has been included in the present specification is not to be taken as an admission that any or all of these matters form part of the prior art base or were common general knowledge in the field relevant to the present disclosure as it existed before the priority date of each claim of this application.
Throughout this specification the word “comprise”, or variations such as “comprises” or “comprising”, will be understood to imply the inclusion of a stated element, integer or step, or group of elements, integers or steps, but not the exclusion of any other element, integer or step, or group of elements, integers or steps.
SUMMARYAccording to the present invention, there is provided a locking support for decking boards or the like including a support element defining a wall portion and at least two generally planar support portions disposed on opposed sides of the wall portion for supporting the underside of a decking board, the wall portion defining a generally cylindrical or part cylindrical recess; and an anchoring element having a generally planar top portion, which is preferably generally semi-circular, and a depending stem, located in the recess, the stem being able to turn in the recess and an aperture extending through the stem for receiving the shaft of a fastening means for fixing the anchoring element relative to the support element.
Advantageously, the fastening system allows decking boards to be laid and fastened in place but subsequently removed e.g. for replacement or repair, or to allow access to areas covered by the boards.
Each planar support portion may define an aperture, preferably a generally D-shaped aperture.
Typically, the semi-circular perimeter edge of the top portion of the washer is knurled.
The washer should preferably be rigid and is typically made of a metal or very strong plastic such as glass reinforced nylon.
Typically, the generally cylindrical or part cylindrical recess defines an upper portion having a larger internal diameter and a lower portion having a smaller internal diameter. The stem of the washer is a close fit inside the upper portion of the generally cylindrical or part cylindrical recess.
In a related aspect, the invention provides a method of assembling a floor comprising decking boards defining slots extending along opposed side edges of the board, the floor being supported on bearers using a decking support as described above, comprising the steps of:—
locating a first pair of supports on a bearer;
supporting a first board on the planar portions of the supports;
adjusting the washer so that part of the top portions of one washer extends into a slot in the side of the decking board; and
fixing the washer using a removable fastener such as a screw extending through the stem into the support and into the bearer.
A specific embodiment of the present invention will now be described, by way of example only, and with reference to the accompanying drawings, in which:—
Referring to the drawings,
A series of three support elements 14 (of which one is hidden) are attached to the upper surface of the bearer, on top of which two decking boards 16 are located. The support elements are shown in more detail in
As can be seen in

In use, with reference to
A second board (not shown) is then located adjacent the first board on the support and a further support is slipped under the distal side of the second board. The washer in the first support is rotated through 90° to the position shown in
The head of the screw is visible between the boards and can be accessed and partially unscrewed to allow rotation of the washer to allow the removal of individual or multiple boards, as illustrated in
While the use of the semi-circular washer allows for the easy removal and replacement of boards, the supports may be used with square washers and the like, which do not have the advantage of being removable, but can be used where the boards do not need to be removed. Also the provision of the three bores in the centre of the support, allows the supports to support and fix the ends of two boards butted end to end, simultaneously.
In particular,
It will be appreciated by persons skilled in the art that numerous variations and/or modifications may be made to the above-described embodiments, without departing from the broad general scope of the present disclosure. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive.
Claims
1. A locking support for decking boards including a support element defining a wall portion and at least two generally planar support portions disposed on opposed sides of the wall portion for supporting the underside of a decking board, the wall portion defining a generally cylindrical or part cylindrical recess; and
- an anchoring element having a top portion and a depending stem, located in the recess, the stem being able to turn in the recess and having an aperture extending through the stem for receiving the shaft of a fastening means for fixing the anchoring element relative to the support element.
2. A locking support for decking boards as claimed in claim 1 wherein the top portion of the anchoring element is generally planar and generally semi-circular.
3. A locking support for decking boards as claimed in claim 1 wherein each planar support portion of the support element defines an aperture.
4. A locking support for decking boards as claimed in claim 3 wherein the aperture is generally D-shaped.
5. A locking support for decking boards as claimed in claim 2 wherein the generally semi-circular top portion defines a semi-circular perimeter edge which is knurled and defines a series of ribs.
6. A locking support for decking boards as claimed in claim 5 including an indicia located part way around the semi-circular perimeter edge of the washer.
7. A locking support for decking boards as claimed in claim 1 wherein the generally cylindrical or part cylindrical recess defines an upper portion having a larger internal diameter and a lower portion having a smaller internal diameter.
8. A locking support for decking boards as claimed in claim 7 wherein the stem of the washer is a close fit inside the upper portion of the generally cylindrical or part cylindrical recess.
9. A locking support for decking boards as claimed in claim 8 wherein the upper portion of the bore defines an inwardly directed protrusion and the stem of the washer defines a recess which can receive the protrusion when aligned with the same.
10. A method of assembling a floor comprising decking boards defining slots extending along opposed side edges of the board, the floor being supported on bearers using the decking support as claimed in claim 1, comprising the steps of:—
- locating a first pair of supports on a bearer;
- supporting a first board on the planar portions of the supports;
- adjusting the washer so that part of the top portions of one washer extends into a slot in the side of the decking board and
