Description

KIT

Field of invention

The present invention relates to a kit.

In particular, the present invention relates to a kit from which it is possible to prepare a series of items for use in sports. The present invention also relates to an item or a series of items prepared using the kit.

Background

Board sports are becoming increasingly popular. Examples of board sports include the use of snow boards, skis, sand boards, paddle boards, windsurfer boards, kite surfer boards, wake boards, body boards, skim boards, and surf boards. These boards and other examples of boards are referred to as sport boards.

The performance of a sports board may be dictated by its length, widths, thicknesses, profile of the outer surface of the front side, profile of the outer surface of the reverse side, edges, materials etc. In addition, it is to be noted that not one sport board will be applicable to all conditions for that sport.

Hence, the user is confronted with many choices -and one particular sport board may not suit all conditions.

Users of sport boards are sometimes faced with problems. For example, the predicted conditions (e.g. of the snow or the surf or the wind) are not always 100% accurate -meaning that the user may be faced with an inappropriate sport board for the condition, or that he/she would have taken a more appropriate sport board if the weather conditions had been predicted to a 100% accuracy.

As another example of a problem, conditions often change during the day (such as the heat of the sun may affect snow conditions, tides change surf conditions etc.).

Thus, if the user has just one board with him/her, then he/she may not have a sport board that could suit all conditions for that day.

As another example of a problem, users are often faced with minimal packaging space (in particular on some airlines or with some vehicles) -meaning that they may only be able to take one sports board with them. This may be problematic if it is not possible to hire additional sports boards at the destination. It may also be problematic if the user would like to combine sporting activities -such as windsurfing and surfing -and he/she can only take with him/her one board for one activity.

Broad aspect of the present invention The present invention seeks to provide a solution to at least the aforementioned problems.

The present invention provides a kit capable of forming a series of sport board assemblies.

Each sport board assembly comprises a middle section and a top section and a bottom section, each of which sections has an upper side and a lower side.

At least one of the top section and the bottom section is securably mountable to and releasable from the middle section.

The kit comprises at least said middle section and said top section and said bottom section.

If the top section is securably mountable to and releasable from the middle section then the kit comprises at least two different top sections each of which is securably mountable to and releasable from the middle section.

In addition or in the alternative, if the bottom section is securably mountable to and releasable from the middle Section then the kit comprises at least two different bottom sections each of which is securably mountable to and releasable from the middle section.

Suriboards The present invention will now be described with reference to surfboards.

However, the teachings herein are applicable to other sports boards -such as snow boards, skis, sand boards, paddle boards, windsurfer boards, kite surfer boards, wake boards, body boards, skim boards, etc. In this respect, whilst references are made to surfboards and certain surfboard terminology has been used, it is to be understood that some or all of the teachings apply to other sport boards of the present invention (such as snow boards, skis, sand boards, paddle boards, windsurfer boards, kite surfer boards, wake boards, body boards, skim boards) and that the equivalent terminology applies.

Surfboards are known. Examples of some surfboards are shown in Figures 1 to 3.

With reference to Figure 1: the surfboard (1) has a front side (or upper side) (3) and a reverse side (or back side or underside) (10). The user typically stands on the front side (3).

The board (1) comprises a top end -which is generally referred to as the nose (15).

The nose (15) is typically the region that extends 12" down from the tip of the board (1).

The board (1) comprises a bottom end -which is generally referred to as the tail (20). The tail (20) is typically the region that extends 12" up from the base of the board (1).

The front side (3) has a section known as the deck (25) between the nose (15) and the tail (20). The user stands on the deck (25) when he/she has caught a wave.

Typically, the deck (25) and in some instances the nose (15) andlor the tail (20) are at least partly coated in a material (not shown) -such as a wax -to improve the adhesion of the user to the board (1) whilst in use. It is possible to obtain waxes and the like (not shown) for a number of water temperatures -such as wax for cold water, wax for cool water, and wax for tropical water. Occasionally, users apply deck grips (not shown) to the deck (25) and/or the tail (20). A deck grip (not shown) is typically a rough-surfaced material (sometimes 2 to 4 cms thick) that is secured to the surfboard by means of adhesive (not shown).

The outer edges (30) of the surfboard (1) are often referred to as the rails (30). The rails (30) are typically the edge of the surfboard (1) where the deck (25) wraps around from the front side (3) to meet the reverse side (10). The rails can have many profiles.

Rails can be described in general terms like hard and soft. They can also be described by their shape characteristics and proportionately as a ratio of distance of the widest point between the deck and the bottom of the board. A round rail is a rail that is almost a complete semi-circle. An egg rail is like a round rail but has an ovoid profile. A down rail comes to an edge at the bottom of the board. A rolled rail is like a down rail but is rolled under the board.

Fuller rails carry more foam -thus providing floatation. Thinner tapered rails carry less foam -thus making it easier for the user to lean on an edge as they are less buoyant. Typically, hard rails do not penetrate the water well at high speeds, whilst softer rails provide a smoother response.

The surfboard (1) is typically formed from shaping a single blank (not shown) or it is injection moulded (not shown) in one piece.

Surfboard blanks are typically foam blocks that are then shaved to the desired profile. The type of blank will largely dictate the strength of the surfboard -in particular the resistance of the surfboard (e.g. the deck) to dents (sometimes referred to as dings). Typically, the heavier the foam of the blank, the better the strength and resistance to dents on the deck. Blanks are typically classified according to foam weight -viz: competition light, light, medium and heavy. Blanks may be made from polystyrene (typically used in combination with epoxy resins) or polyurethane (typically used in combination with polyester resins).

During manufacture, the surfboard (1) is often strengthened by use of a material (35) that extends from the nose (15) to the tail (20). That material is often referred to as the stringer (35). The stringer (35) typically comprises wood or a wood composite or a glue. The stringer (35) generally runs down the centre line of the surfboard (1). The stringers provide strength to the surfboard (1). Some surfboards have a plurality of stringers (not shown).

The nose (15) can have different profiles -ranging from a round profile to a pointed profile.

The tail (20) can have many profiles -ranging from a rounded profile ("round tail"), pin, rounded pin, square tail, squash tail, to cut-in sections to an inset section (e.g. in the shape of a "V" -and is sometimes referred to as a "swallow tail"). With a round tail, the two sides of the surfboard come together in smooth curves to form a semicircle. With a square tail, rails end suddenly, forming a box shape. A squash tail is like a square tail but wherein the square tips are softened. With a swallow tail, the rails end suddenly and a "V" is cut back in towards the stringer.

The distribution of foam from the nose (15) to the tail (20) on the surfboard is known as surfboard foil. If there is excessive foam left in one area -such as the nose or the tail -then the surfboard in use becomes unbalanced. In contrast, a more even distribution of foam will help performance.

When the desired surfboard profile has been prepared, a protective coating is applied over the exterior of the shaped profile. This is typically referred to as glassing. Before the glassing stage, typically the surfboard structure is toughened with fibreglass (typically saturated with resin). Here, fibreglass strips are used to laminate the board and thereby produce a hard outer surface. The fibreglass is often used as fibreglass cloth. Here, glass fibres that are woven into a cloth with weights of about 4ozJl square yard of cloth or about 6oz/1 square yard of cloth or about lOoi/1 square yard of cloth, etc. Generally, the fibres are stronger the heavier the weight of the cloth.

In some instances, carbon fibres (sometimes soaked in resin) are laid in strips along the length of a board during glassing to help prevent creasing.

There are available many types of resins that can be used in the production of a surfboard. Typically, a catalyst is used to harden the resin -such as a polyester resin. The time taken for the resin to harden can depend on the amount of catalyst andlor the amount of UV radiation andlor the ambient air temperature.

Surfboard blanks may be formed from polyurethane.

Surfboards may also be formed from expanded polystyrene foam (EPS). Typically EPS foam is used with an epoxy resin to form the surfboard. Generally, EPS foam blanks are very light in weight. Surfboards may also be made from extruded polystyrene foam (ExPS). ExPS foam has a more closed cell structure than EPS foam -making it more strong and more water resistant.

Moulded boards are typically prepared by injecting a plastic moulded shell with expanding foam. Examples of such surfboards are sold by BiC Surfboards.

Some surthoards are made of wood materials, such as balsa wood.

The rocker of a surfboard is the side shape of the surfboard. It is usually further defined as being the top rocker and the bottom rocker. The typical design of a surfboard comprises a flatter curve in the middle of the surfboard, with ever-increasing curves towards the nose section and the tail section. The design of the bottom rocker that includes the tail section of the surfboard can determine the turning characteristics of the surfboard. The design of the top rocker that includes the nose section of the surfboard can determine how easy it is to catch a wave or how much wind resistance the surfboard encounters whilst in use.

The reverse side (10) is often sloped upwards towards the nose (15). The reverse side (10) may include design feature that affect the performance of the surfboard (1). Examples of designs include: flat bottoms, concave designs, Vee design, channels, and combinations thereof. The concave design can yield lift and drive during use.

In the portion at or near to the tail (20) are one or more fins (not shown). Fins are used to assist the control, direction and drive of the surfboard by the user. Many different fin shapes are available. In addition, fins are made out of many different materials are available.

Typically, the fins are located in one or more fin housing boxes (60, 65, 70). Some surfboards have one fin housing box (70). The fins (not shown) are secured into the fin housing boxes (60, 65, 70) by means of suitable locking arrangements. An example of a fin system and locking arrangement is FCS (Fin Control Systems) fins.

Some suriboards have two fin housing boxes (65, 60). Some surfboards have three fin housing boxes (60, 65, 70). Some surfboards have four fin housing boxes (not shown) or even five fin housing boxes (not shown). With a plurality of fin housing boxes, the user can decide bow many fins he/she wishes to use and in a particular configuration. A three fin configuration is typically known as a "thruster set-up".

Other configurations are sometimes called "twin-fin set-up", "quad-fin set-up", etc. The surfboard (1) usually has a securement point (40) to which the user can attach a leash (not shown). The leash is used to attach the user to a surfboard. It is sometimes referred to as a leg rope. The leash is typically a strong elastic polyurethane cord that has at one end a band (not shown) that can form an adjustable collar (not shown) that can be used to secure the collar (and thereby the surfboard) to the ankle or knee of the user. Typically, the collar is securable by Velcro (not shown).

In some instances, the nose may be provided with a guard -sometimes referred to as a nose guard (not shown). Typically the nose guard is adhered to the nose of the surfboard and to provide protection to the actual tip of the surfboard. Nose guards may be formed from any suitable material -such as silicon tip. a

Typically, three key surfboard dimensions are noted. The dimensions are quoted in Imperial lengths (feet () and inches (")).

The first dimension is the length -which is typically measured from the tip of the nose to the end of the base. Typically, the longer the surfboard, the more floatation there is. Also, longer surfboards can be paddled with more ease, and enable the user to catch waves more early. Typically, shorter surfboards turn easier. Generally, short boards are more sensitive to weight transfer.

The second dimension is the width -which is typically measured across the greatest width of the deck (25). The wider the surfboard the more foam it contains -which enhances floatation of the surfboard. Typically, narrow boards are more suited to fast hollow waves. Generally, surfboards with wider noses are easier to paddle easier, whereas narrower noses enhance movement. Generally, surfboards with a wider tail feel looser at low speeds than surfboards with a narrower tail. Typically, surfboards with a narrow tail are better suited for larger and hollower surf conditions.

The third dimension is the thicknesses -which is typically measured as being the distance the outer surface of the front side (25) and the outer surface of the reverse side (10).

Additional dimensions are other widths along the length of the board from nose to tail. For example, nose width is typically measured 12" down from the tip towards the base. Tail width is typically measured 12" up from the base towards the tip.

Surfboards are typically classified depending on the inter-relationship of these three dimensions (i.e. length, width and thickness). Examples of surfboard types are: long boards; fish; short board; contemporary short board; mini-mal; gun; mini-gun; semi-gun; egg; fun board; rhino chaser; retro surfboard, a hybrid surfboard and a soft board.

By way of example, short boards are usually between about 516u to about 7'O" long, with a width between about 16" to about 19", and a thickness from about 1.75" to about 2.75". Depending on the profile of the short board, the nose width can vary from about 10" to about 12", whereas the tail width can vary from about 12.5" to about 14.5". The bottom rocker may be about 5" to 6" in the nose, and from about 2" to 3" in the tail.

By way of further example, long boards are usually between about 6' to about 12' long (typically between 8'6" to 10'6"), with a width between about 20" to about 26", and a thickness from about 2.5" to about 4". Depending on the profile of the long board, the nose width can vary from about 15" to about 20", whereas the tail width can vary from about 12" to about 15.5". The bottom rocker may be about 5" to 6" in the nose, and from about 2" to 5" in the tail. Typically they have a rounded nose.

The tail shapes are generally square or rounded-pin shapes.

By way of further example, hybrid boards are intermediate a long board and a short board. They are usually between about 6'S" to about 9' long, with a width between about 20" to about 23", and a thickness from about 2.5" to about 3.5". Depending on the profile of the long board, the nose width can vary from about 13" to about 17", whereas the tail width can vary from about 13" to about 16". The tail is generally square.

By way of further example, an egg is similar to a hybrid. The egg typically has a rounded-pin tail.

By way of further example, a fish (Fish or FISH) comprises a wide nose and broad swallow-type tail design, with a twin-fin setup. But recently, the term generally refers to any short, stubby, wide surfboard.

By way of further example, a fun board has dimensions that combine the float of a long board (enabling a user to paddle out into the waves easier) but does not have the length and volume as a long board.

By way of further example, a soft board typically has a deck constructed of a strong foam-like material. In some instances, the bottom of the surfboard is also of a firm foam-like material.

S With reference to Figure 2: the surfboard (200) has a front side (or upper side) (203) and a reverse side (or back side or underside) (not shown). The board (200) comprises a nose (21 5). The board (200) comprises a tail (220). The front side (203) has a deck (225). The surfboard (200) has rails (230). The surfboard (200) has a stringer (235). The nose (215) has a pointed profile.
