Abstract

The utility model relates to an improvement of fin-shaped rudder structure of surfboard. The utility model improves traditional method of direct molding with materials of resin and fiberglass and honeycomb group made up of a plurality of hollow frame bodies is set in the fin-shaped rudder. Covers are set in the front and back of the honeycomb group to form an air house by sealing the transfixion room in the front and back of the hollow frame bodies. This air house is covered with resin and fiberglass on the outside surface. The utility model has the advantages of low cost, simple manufacturing, light in weight and better surfing flotage to prevent falling.

Description

Surfboard fin structural improvement

Technical field

In order to the fin of leading, take a lot of work by making at unrestrained plate in the tradition for the utility model, quality is heavy, increased the following gravity that draws of surfboard, and institute is researched and developed to form, but cost-cutting, and surfboard fin structural improvement simple for production, the good light weight again of buoyancy.

Background technology

Human itself promptly have curiosity, imitate and think deeply the ability of creation, and the ability of thinking creation is exactly a general animal part can't be obtained, and this also is why the mankind can manage one of all things on earth reason, even amusement also is the some of human thinking creation.As surfing, the former amusement that stems from locality, Bo Lini owned by France XiLi, the South Pacific (being commonly called as Tahiti), introducing Hawaii afterwards is not broken into long healthy and strong, luxuriant is agitation, up to after the nineteen sixty, because structure of surfboard be manufactured with good improvement, so the development of surfing also relatively and then flourishing get up.Formerly pass to the U.S., imported Australia, continent, South America again into after receiving an acclaim in earlier 1900s, even all over the world.Now, almost each state has admitted that all surfing is a formal sports events.

Surfing is the water activity of test balance sense and an alerting ability, the power that relies on wave to advance, and surfboard steps down in buoyancy on the wave and shuttles back and forth waterbornely, and this surfboard is exactly a necessity of being engaged in this motion.This motion is at first to go to sea by ground dividing plate the faintest between a section wave, then when an initial wave peak, off-lying sea, the acceleration of striking of taking advantage of a situation, just arrive when the wave crest, moment thirty years of age of riding boogie board, against moving flexibly and health pitching equilibrium establishment of both feet, just can in wave, freely make a return journey.

General surfboard needs according to its build and user, roughly be divided into long slab, short slab (claiming the technology plate again), gunwale (GUN BOARD), but its basic structure is constant, as shown in Figure 1, is little gesture that upwarps in surfboard body 10 front portions 11, mainly be leading for surfing easily, wave can be made come-up along introducing body 10, and be provided with three fins 20, as Fig. 2 in body 10 tail end bottoms, each fin 20 top is provided with tenon 21, to be used for fixing in surfboard body 10 desired locations; The purpose of this fin 20 is to make body 10 have directional balance, if there is not this fin 20, when surfing, surfboard with regard to the influence that is subjected to wave easily and about float indefinitely, it is just as the function of rudder for ship.

Therefore, this fin is the indispensable formant of surfboard, if there is not it to exist, then surfboard will lose its balance, direction, unsteady effect, and the material of fin and weight thereof also can have influence on the stability of floating of surfboard and operation.At present industry is to make it have more light weight to have the characteristics of economic benefit again, all forgoes wooden and uses the fin of being made by resin and glass fibre instead.Yet this kind design, though can save cost of manufacture, expendable weight, but still it is heavy to avoid having cooresponding matter, when surfing, because of the people stands on the surfboard, because of the weight of fin, often make the surfboard rear end be easy to first sinking, and can't make the surfer on wave, keep the surfing time more of a specified duration, and this also makes surfboard can't really conform with light weight, unsteady positive meaning, and this is that present industry utmost point desire is improved part.

The utility model content

The structure improved design goal of the utility model surfboard fin provides and make to save cost, easy, light weight, the strong fin structure of power of floating.

The technical scheme that the utility model adopted is: a kind of surfboard fin structural improvement, it focuses on, and is to be provided with the honeycomb hole group of being made up of a plurality of hollow frameworks of number in fin, is provided with the lid cover before and after the group of honeycomb hole, coats and moulding with cemented thing.This lid is located between honeycomb hole group and the cemented thing.This cemented thing is resin and glass fibre, or other has the material of hard a piece of wood serving as a brake to halt a carriage light weight.

The utility model surfboard fin structural improvement is to be provided with the honeycomb hole group of being made up of most hollow frameworks in it, reduces weight by this, also utilizes its hollow framework cause just as the air bag effect, is difficult for sinking to reaching the short unsteady effect that increases and reach.

[figure number explanation]

20 fins, 31 honeycomb hole groups

21 tenons, 32 lids

22 cemented thing 311 hollow frameworks

The specific embodiment

So the utility model surfboard fin structural improvement possesses cost-cutting, simple and convenient, the unsteady power that can increase surfboard is difficult for sinking, and the prolongation surfboard floats on the time on the tide, makes the characteristics that have more progressive.

Shown in Fig. 3～5, in fin 20, be provided with the honeycomb hole group of being formed by most hollow frameworks 311 31, all being provided with lid 32 in these group 31 front and back, honeycomb hole covers each hollow framework 311, form similar balloon-like, outside lid 32, spread cemented thing 22 again, whole honeycomb hole group 31 and lid 32 are coated on interior moulding.

Wherein, the empty group of honeycomb shown in the figure 31 hollow frameworks 311 embodiment be the hexagonal shape, in fact can comply with to be designed to cubic type, circle or other has the body of hollow frame.

In addition, being located at the lid 32 on the honeycomb hole group 31, mainly is that cemented thing 22 is separated with honeycomb hole group 31, make when spreading cemented thing 22, unlikely the falling in the hollow framework 311 in side, so this lid 32 can be cemented driving fit or the non-shape that closes admittedly when combining with honeycomb hole group 31.

And this cemented thing 22 can be the resin 23 and the glass fibre 24 of traditional fin raw material, or other has the material of hard a piece of wood serving as a brake to halt a carriage light weight.

By the design of honeycomb hole group 31, not only the weight of the fin of at present entirely making with resin and glass fibre 20 come light, but and simply also cost-cutting on making, can increase the unsteady power of surfboard on tide.

In sum, the utility model surfboard fin structural improvement is cut and has really been met practical value and economic benefit, possesses the positive important document of novel patent, so propose patent application in accordance with the law.

Above act is not limited to this patent into feasible enforcement example of the present utility model, so allly do not exceed the result that any change that this creation spirit does or equivalence are replaced, all should belong to claim of the present utility model.
