The ninth figure shows an exploded view of a conventional surfboard.

The first to sixth figures show a preferred embodiment of the surfboard 1 of the present invention. The first figure shows a three-dimensional appearance of the surfboard 1. The surfboard 1 includes a plate body 2, a bottom plate 4 attached to the bottom surface of the plate body 2, and a tail rudder structure fitted to the plate body 2 and the bottom plate 4. Referring to the second figure, the plate body 1 includes a foam core plate 21 and a foaming seat body 22. As shown in the second to fourth figures, the rudder structure includes two bolt bases 3, a rudder base 5, two joint pillars 6, and a tail rudder 7. Since the two bolts 3 are directly fitted to the plate body 2 and the bottom plate 4, the rudder base 5, the two coupling posts 6 and the tail rudder 7 are combined with the two bolt seats 3, so that the tail rudder structure is prevented from being exposed. The bottom surface of the plate body 2.

Referring to the second to fourth figures, the foaming seat 22 of the plate body 2 is embedded in the bottom of the foam core plate 21 and exposed to a bottom surface 211 of the foam core plate 21. An engaging groove 221 is defined in the foaming seat body 22. The two sockets 3 are embedded in the foaming base 22 of the plate body 2, and each of the bolts 3 has a coupling hole 30 exposed to the bottom surface 211 of the foam core plate 21.

In the embodiment, the specific process of combining the foam core plate 21, the foaming seat body 22 and the two bolt seats 3 is to first fix the two bolt seats 3 to a mold cavity (not shown). The pre-expanded beads of the foaming body 22 are continuously filled into the cavity of the mold, and the mold is heated so that the pre-expanded beads therein are respectively expanded into a single piece due to heat. Foamed particles, the surfaces of the foamed particles are slightly fused by heat, and adhere to each other due to the pressure in the mold so as to be bonded to each other to form a cavity shape corresponding to the mold The foaming seat body, the two bolt seats 3 in the mold are also embedded by the bonding and coating of the foaming particles. In the foaming body 22 of the plate body 2. Then, the foaming body 22 is further embedded in the foam core plate 21 through the foregoing process. Preferably, the surface of the foaming body 22 may be pre-coated with a layer of adhesive, thereby further expanding the foam core plate 21. Firmly combined (not shown). Referring again to the second figure, the bottom plate 4 is attached to the bottom surface 211 of the foam core 21 and also to a bottom surface 222 of the foam base 22. The bottom plate 4 has a receiving hole 41 communicating with the engaging groove 221 of the foaming base 22, and two through holes 42 communicating with the coupling holes 30 of the two sockets 3, respectively.

Referring to the second to fourth figures, the rudder base 5 has a body 51 and an extension plate 53 extending from the bottom periphery of the body 51. The body 51 extends through the receiving hole 41 of the bottom plate 4 and engages with the engaging groove 221 of the foaming seat 22 , and the body 51 has a rudder groove 52 . The rudder 7 is disposed in the rudder groove 52 of the body 51 of the rudder base 5. One end 61 of each binding post 6 is connected to the rudder base 5, and the other end 62 correspondingly penetrates into the through hole 42 of the bottom plate 4 and is fitted into the coupling hole 30 of the corresponding bolt seat 3, so that the rudder base 5 is fixed to The foaming seat 22 is in the engaging groove 221. In the present embodiment, the binding posts 6 are integrally formed on the extension plate 53 of the rudder base 5.

Through the above arrangement, the tail rudder 7 of the surfboard 1 can be firmly coupled directly to the board body 2 by the rudder base 5.

Preferably, referring to the second figure, the foam core 21 is made of a first foam material, and the foam base 22 is made of a second foam material, and the second foam material is The first foaming material is tough, and in the embodiment, the first foaming material is foaming polystyrene (EPS), and the second foaming material is foamed ethylene polymer (EPO), that is, Copolymer of foamed polyethylene (EPE) and expandable polystyrene (EPS), but not limited to this. Through the above arrangement, when the tail rudder 7 is impacted by an external force, the relatively strong foaming seat body 22 can first absorb and buffer the stress transmitted from the tail rudder 7 and then transmit it to the foam core plate 21 to avoid the fragile The foam core plate 21 is directly damaged by an external force and is prevented from being cracked by the impact between the plate body 2 and the socket 3 due to an external force impact, so that the socket 3 is detached from the plate body 2. In addition, referring to the fourth and sixth figures, the top portion 223 of the foaming seat body 22 is laterally convex to form a protruding portion 224 to prevent the foaming seat body 22 from coming off the foaming core plate 21. Thereby, the tail rudder 7 of the surfboard 1 can be firmly coupled to the foam core board 21 by the rudder base 5 and the foaming seat body 22.

The bottom plate 4 is made of a rigid material. In this embodiment, a non-foamed plastic material such as non-foamed low-density polyethylene, high-density polyethylene or low-density polyethylene is used, but not limited thereto. Similarly, the two sockets 3 are made of a rigid material, which is non-foamed in this embodiment. Made of plastic, such as low density, medium density or high density polyethylene, but not limited to this. Preferably, the two sockets 3 are further firmly joined to the foaming seat 22 by an adhesive (not shown).

Referring to Figures 5 and 6, each of the sockets 3 includes a tubular body 31, a top plate 32 and two reinforcing ribs 33. The tubular body 31 defines a coupling hole 30 in the socket 31. The top plate 32 is integrally formed on the top of the tubular body 31. The width of the top plate 32 is larger than the diameter of the tubular body 31 to prevent the socket 3 from being separated downward. The foaming base 22 is connected to the tubular body 31 and the top plate 32 to strengthen the structure of the socket 3. Each of the sockets 3 is formed with a plurality of air-permeable fitting holes 34 on opposite sides of the hole wall of the coupling hole 30. The air-permeable fitting holes 34 enable the entire socket 3 to directly pass through the plastic. The injection molding is made without further processing of the groove that meshes with the coupling posts 6 after the mold is removed. A plurality of fitting teeth 63 are protruded from the side edges of each of the binding posts 6 for fitting to the fitting holes 34 of the corresponding sockets 3.

Referring to Figures 3 and 4, the extension plate 53 of the rudder base 5 is integrally formed with the two coupling posts 6. The main body 51 of the rudder base 5 has two staggered fixing holes 54 extending obliquely through a bottom surface 531 of the extension plate 53 and the groove wall of the rudder groove 52, so that the two bolts (not shown) can be The two fixing holes 54 are respectively inserted to fix the tail rudder 7 in the rudder groove 52 of the body 51 of the rudder base 5.

7 and 8 show another preferred embodiment of the present invention. The structure and function of the surfboard 8 in this embodiment is substantially the same as that of the surfboard 1 in the previous embodiment, the only difference being that the surfboard The two coupling posts 83 of the 8 are not integrally formed with the extension plate 82 of the rudder base 81, but are assembled to the extension plate 82. In detail, the extension plate 82 of the rudder base 81 of the surfboard 8 defines two through holes 820 penetrating therethrough. The two binding posts 83 of the surfboard 8 respectively penetrate through the corresponding engaging holes 820 of the extending plate 82, the corresponding through holes 840 of the bottom plate 84 and the corresponding engaging holes 850 in the sockets 85 thereof, so as to connect the rudder base 81 and the pedestal 81 85 combined.

Through the foregoing arrangement, the surfboard of the present invention provides a novel structure, so that the rudder can be firmly combined with the slab, and the rudder can be prevented from being detached from the slab due to external impact of the rudder or the slab is destroyed. problem.

In any event, anyone can obtain sufficient teaching from the description of the above examples, and it is understood that the present invention is indeed different from the prior art, and is industrially usable and progressive. It is the invention that has indeed met the patent requirements and has filed an application in accordance with the law.
