Description

DESCRIPTION

Surf table

TECHNIQUE SECTOR

The present invention refers to a surfboard, of the so-called "soft" type, which has a structure that prevents the board from absorbing water inside over time when it suffers a scratch, which It has a very negative effect on the overall weight.

BACKGROUND OF THE INVENTION

In the field of practical application of the invention, surfboards made from low-density materials that give them high buoyancy are known, such that said materials, being highly spongy, are capable of absorbing water inside, as is the case of expanded polystyrene-EPS, for which the table is covered with layers of water-repellent material that avoids this problem.

However, it is relatively frequent that the boards end up hitting some rock or element that could damage this coating, so that through the hole or holes created in said scratch, the water gradually enters the core of the board, very negatively affecting the surface. its weight and therefore its maneuverability.

EXPLANATION OF THE INVENTION

The table that the invention proposes fully satisfactorily resolves the previously exposed problem based on a highly efficient structuring.

To do this, and more specifically, it is made from a core of extruded polystyrene-XPS-(foam), which is cut and shaped, obtaining two semi-cores that are joined to each other laterally with the interposition of a profile of wood or "stringer".

The water-repellent nature of this material prevents water from being absorbed by said core if the covering layers of said core are damaged.

The core is covered on both sides with fiberglass and resin, so that once the inserts for the plugs have been made, a layer of soft foam with a thickness of 0.1 to 0.5 mm is added on the underside, as for example polyethylene foam and a layer of hard plastic between 0.1 and 0.5 mm thick.

Finally, the upper face is covered with materials such as EVA rubber, polyethylene foam or PVC foam to give it a soft finish.

From this structuring, a totally waterproof surfboard is obtained, which, even when its protective layers are damaged, prevents water from penetrating into the core of the board, preventing it from increasing its weight, to which must be added the fact that the material used for the core has a higher mechanical resistance than EPS, which improves the appearance of the board with continued use since it presents fewer bumps or cracks.

BRIEF DESCRIPTION OF THE DRAWINGS

To complement the description that is going to be made below and in order to help a better understanding of the characteristics of the invention, according to a preferred example of its practical embodiment, a set of drawings is attached as an integral part of said description. where, with an illustrative and non-limiting nature, the following has been represented:

PREFERRED EMBODIMENT OF THE INVENTION

In view of the outlined figures, it can be seen how to obtain the surfboard of the invention, starting from a rectangular extruded polystyrene foam sheet (1), which is cut longitudinally and to size to obtain two semi-cores ( 1'-1'') that are fixed laterally by means of a wooden profile (2).

This process can be done in three different ways:

• Cutting the plank, adhering the wooden profile with the desired curve helping us with pressure.

• Cutting the plate, adhering the wooden profile with the desired curve helping us with heat.

• Cutting the initial plate into sections with the profile of the desired curve and finally gluing all the pieces (we are talking about an indefinite number depending on the width of the table, they can be three or more).

As for the method to give these pieces the proper shape, it can be done either by hand or by numerical control (CNC) cutting machine.

According to figure 6, once the core is obtained, it is covered on both sides with a layer of fiberglass and resin (3), so that once the inserts for the plugs are made, a layer is added to the lower face. made of soft foam (4) with a thickness of 0.1 to 0.5 mm, such as polyethylene foam and on top of it a layer of plastic hard (5) between 0.1 to 0.5 mm thick.

Finally, the upper face is covered with a layer of soft material (6) such as EVA rubber, polyethylene foam or PVC foam.
