Description

TECHNICAL FIELD

The present invention relates to a board for water or snow sport, and particularly, although not exclusively, to a water or snow activity board having a protective rail disposed on an edge of the board.

BACKGROUND

A number of water sports or snow activities require the uses of a board. The board is usually a planar body which is arranged to support a rider on a medium such as water, snow or ice whilst the rider is in motion. These boards have an important function of supporting the rider whilst also permitting the rider to interact with the water, snow or ice surface so as to allow the rider to perform various movements or manoeuvres whilst undertaking the water or snow activity.
Examples of these boards include kite boards, wake boards, surf boards, snow boards or the like. These boards are all useful in supporting a rider on water or snow. In the case of kite boards, for example, the rider may be supported on a kite board whilst being powered on the water's surface by a kite. In these cases, the board may be designed so that the when rider applies pressure to certain portions of the board, a change in the balance and/or a change in the water pressure underneath the board will allow the rider to perform certain types of manoeuvres.
Designers have noticed that the shape and profile of an edge of the board will affect the performance of the board in use. This is because the edge will directly interact with the water or snow on which the board is travelling on and usually acts as the starting point in which the board interact with the water or snow during a manoeuvre. In certain situations, the rider may use the edge to dig into the snow or water so as to create turbulence or friction to steer the board or to perform certain types of manoeuvres. As such, the profile of the edge is usually designed for certain types of uses or performances.
However, the leading edge of the board is also a part of the board which is most prone to damage due to collisions or rough transportation. Once damaged, the profile of the edge may be changed and these changes may affect the performance or balance of the board.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference to FIG. 1 there is illustrated a board 100 for water activities comprising a planar body 102 having a rail member 106 arranged to substantially surround an edge 104 portion of the body 102. The board 100, as shown in FIG. 1 is a kite board arranged to support a rider on a water surface whilst the rider is participating in kite surfing. As the person skilled in the art will appreciate, the board 100 may be adapted or modified to act as a wake board, surf board, body board, snow board or any other planar body arranged to support a person participating in any type of sport or activity on water or snow.
As shown in FIG. 1, the board 100 is defined by a generally planar body 102 which is preferably elongated so as to provide sufficient support for the rider on the water or snow surface. The board 100 also includes a plurality of vertices 103 which form the corners of the planar body 102. These vertices 103 are preferably curved so as to form a smooth or curvy profile and in turn are advantageous in that a smooth or curvy profile may reduce friction between the board 100 and the water or snow surface.
The planar body 102 also has an edge 104 which may be arranged and shaped for performance. Preferably, this edge is relatively thin when compared with the planar body 102 so that it can be used by a rider to carve into the water or snow, and in turn manoeuvre the board 100 to a desired position. In one example, where the board 100 is adapted to operate on a water surface, the edge 104 may be shaped so as to carve into the water to create different types of turbulences around the board for user control. In examples where the board is arranged to operate on snow, the edge be even thinner as to perform allow the edge and the board to carve into snow or ice, which in turns increases the friction between the board and the snow or ice surface.
Preferably, the board 100 also includes a protective rail 106 which surrounds either partially, substantially or completely, and encloses the edge 104 of the board. This protective rail 106 is arranged to protect the edge 104 from damage, particularly in situations where the board collides with a hard surface or object during use or transportation.
The protective rail 106 may be made from a plastic material so as to absorb much of the pressure or shock caused from collisions or rough handling. Preferably, as the rail 106 will become a leading edge of the board 100 once integrated with the board's edge 104, the rail 106 may also be arranged to be fairly hard or resilient so as to not substantially deform after an impact. This is advantageous in that a collision experienced by the protective rail 106 will not change the board's edge profile so as to affect its handling characteristics.
Depending on the function of the board and the materials used, the board 100 may be manufactured by a number of different methods with numerous different types of materials. In one example, where the material used includes wood and fibreglass, the board may be made by the following steps:
Step 1—Obtaining a planar wooden plank (or other materials) of sufficient size;
Step 2—Using a CNC router to cut the profile of the board 100 onto the plank to form a profile cut of the board. This may also be referred to as a CNC profile or CNC profile cut; The CNC profile includes a slot which is adjacent to the outline of the board. This slot may then be used to add a protective rail.
Step 3—Bonding one or more protective rails within the slot. These rails may be plastic pieces which are shaped on a cutter or grinder so as to fit the edge profile of the board.
Step 4—After the rails are bonded within the slot, the excess materials of the profile cut can then be removed and thus leaving the protective rail on the edge of the board;
Step 5—Using the CNC router, certain features of the planar surface may be cut or carved on to the planar surface of the board;
Step 6—Apply and bond fibreglass layers to the profile cut. This has the result of adding a layer of skin onto the board. In some examples, paint of a protective layer such as lacquer may also be applied to the surface of the board for protection;
Step 7—Cut away excess fibreglass layers and wood (or other materials) to form the board; and
Step 8—Apply any additional accessories to the board as desired by the rider. These accessories may include anchor points, foot rests or the like.
With reference to FIGS. 2A to 2E, there is illustrated an example of a profile cut of a kite board undergoing steps 2 to 5 mentioned above. As shown in FIG. 2A, a planar plank of timber of sufficient size is cut by a Computer Numerical Control (CNC) router so that the general profile of a board 100 is cut into the timber. This creates the profile cut 200 which is subsequently cut into a finished kite board.
As show in FIG. 2B, the profile cut 200 includes a slot 203 around the edge of the profile cut 200. This slot 203 defines the general outline of the finished kite board whereby the slot 203, once further processed, becomes the edge of the kite board. As illustrated in FIG. 2B, protective strips 202 may then be glued to the slot 203 such that when the board is finally finished, these strips 202 protect the edge of the board.
As illustrated in FIGS. 2B to 2D, the protective rails 202 are formed by four strips comprising a top strip 202T, bottom strip 202B and two side strips 202S which are bonded within the slot 203 corresponding to each side of the board.
In the example illustrated in FIGS. 2B to 2D, the strips are formed from a thermoplastic such as Acrylonitrile Butadiene Styrene (ABS) plastic which is mildly flexible so that straight pieces of ABS plastics can be cut into shape and flexed to generally bond to a curved portion of the slot 203 representative of the side of the board. However, as ABS plastics are generally not flexible enough to bend around a vertex of the board 100, four separate strips are used to surround the entire edge 104 of the board 100.
As shown in FIG. 2E, once the strips are glued to the slots of the profile cut 200, additional primers, adhesives or bonding agents are used to ensure the edges remain in position. After the strips are engaged to the slots 203, the profile cut 200 may then be further cut by a CNC router as shown in FIG. 2F so that excess materials are removed from the profile cut 200 to form the board 100. Once this is completed, the board 100 may then be covered and bonded with fibre glass skins, plastics, paint or lacquer.
The procedure described above is advantageous as the construction of the kite board allows the protective strips to be integrated during the construction process and thus forms a much stronger bond between the protective strips 202 and the board.
With reference to FIGS. 3A to 3E, there is illustrated an alterative method of manufacturing a kite board whereby an alternative procedure is used to integrate the protective rail to the kite board. As it will be appreciated by a person skilled in the art, the same procedure can be used to manufacture a board for water or snow sports such as wake boards, surf boards, body boards or snow boards.
In this embodiment, the method for manufacturing a kite board, or any board for a water sport or snow sport includes the steps of: engaging an edge of the sports board with one or more protective strip, wherein each protective strip is sufficiently flexible so as to bend around a vertex of the board to continuously engage with an edge portion adjacent to the vertex of the board.
This method of manufacturing a board, once applied, may in one example produce a water or snow activity board comprising: a planar body having an edge joining one or more vertices of the body, wherein the edge is engaged to a rail member defined by one or more flexible strips each being arranged to be sufficiently flexible so as to continuously engage with an edge portion adjacent to the one or more vertices.
In this embodiment of the method for manufacturing a kite board as shown in FIGS. 3 and 3A to 3E, a profile cut 300 is firstly prepared by a CNC router which cuts the board profile on to a planar plank of wood. Once the profile cut 300 is prepared, a protective rail 303, which may have been formed prior in a separate location from extruded plastic, is placed around the edge slots 303A, shown in FIG. 3, of a profile cut 300 of the kite board and bonded to the edge slots 303A. Once bonded, the protective rail 303 will be exposed on the edge of the board after the manufacturing process finishes and thus protect the edge of the board.
As illustrated, the protective rail 303 is of a sufficient length so as to completely surround the edge of the board in one single elongated strip, although it is also possible that the protective rail can comprise more than one strip. The protective rail 303 in this example is made by extruding Polyurethane plastic through an extrusion aperture to create a long continuous strip of the Polyurethane plastic. However, various other materials can be used to make this protective rail 303 although any flexible and resilient material which allows the strip to bend around the vertices of the board whilst offering shock absorbing characteristics is preferred.
As shown in this example, the protective rail 303 has characteristics which are sufficiently flexible so as to be bended into the slots which correspond to the vertices of the board. The rail 303 is then inserted into the slot 303A and, as shown in FIG. 3C, bonded to the slot such that the rail 303 is bonded to the entire edge of the board. Hammering of the rail 303 into the slot as shown in 3D may also be required as it is preferable that the rail 303 forms a snug fit into the slot 303A.
Once the bonding agent is allowed to set, the rail 303 is thus bonded to the slot 303A of the profile cut 300. The profile cut 300 may then be processed by a CNC router which will cut the shape of the board from the profile cut 300. In this process, since the rail 33 is already bonded to the slot 303A, the rail 303 will be bonded to the edge of the board and form the board's protective rail 303 after the excess materials of the profile cut 300 is cut away by the CNC router.
These embodiments are advantageous in that by using a flexible material such as polyurethane or the like, the protective rail can be bonded to the board as one continuous strip. As the material is sufficiently flexible, the strip can be continuously bonded to the vertices of a board as the strip, due to its flexibility, is able to bend to the minimum radius of the board vertices or outline. This property in turn minimises the time required to bond a protective strip to the edge of the board. Furthermore, by using more flexible materials such as polyurethane plastic to manufacture the strip, there is less wastage of materials as would be the case of harder materials with less flexibility such as ABS plastic strips which needs to be machined and cut to fit the edge of a board.
It will be appreciated by persons skilled in the art that numerous variations and/or modifications may be made to the invention as shown in the specific embodiments without departing from the spirit or scope of the invention as broadly described. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive.
Any reference to prior art contained herein is not to be taken as an admission that the information is common general knowledge, unless otherwise indicated.
