Abstract

A surfboard is provided, which may include a first air chamber, a second air chamber, and a partition arranged between the first air chamber and the second air chamber. The partition may comprise: a first connecting portion connected to a top wall of the first air chamber and to a top wall of the second air chamber; a second connecting portion connected to a bottom wall of the first air chamber and to a bottom wall of the second air chamber; and an intermediate portion extending between the first connecting portion and the second connecting portion.

First claim

What is claimed is:

1. A surfboard, comprising:
a first air chamber and a second air chamber; and
a partition arranged between the first air chamber and the second air chamber, the partition comprising:
a first connecting portion connected to a top wall of the first air chamber and to a top wall of the second air chamber, the first connecting portion comprising two top wall connecting pieces, each of the two top wall connecting pieces comprising an extension piece extending between the first air chamber and the second air chamber;
a second connecting portion connected to a bottom wall of the first air chamber and to a bottom wall of the second air chamber, the second connecting portion comprising two bottom wall connecting pieces, each of the two bottom wall connecting pieces comprising an extension piece extending between the first air chamber and the second air chamber; and
an intermediate portion extending between the first connecting portion and the second connecting portion;
wherein:
a first end of the intermediate portion is integrally formed with one of the extension pieces of the two top wall connecting pieces and is connected to the other extension piece of the two top wall connecting pieces; and/or
a second end of the intermediate portion is integrally formed with one of the extension pieces of the two bottom wall connecting pieces and is connected to the other extension piece of the two bottom wall connecting pieces.

2. The surfboard according to claim 1 , wherein the first air chamber comprises a first air valve, and the second air chamber comprises a second air valve.

3. The surfboard according to claim 1 , wherein each of the first air chamber and the second air chamber comprises a drop-stitch material.

4. The surfboard according to claim 1 , wherein:
the first end of the intermediate portion is connected to the one extension piece of the two top wall connecting pieces by at least one of high-frequency welding, hot melting, and gluing; and/or
the second end of the intermediate portion is connected to the other extension piece of the two bottom wall connecting pieces by at least one of high-frequency welding, hot melting, and gluing.

5. The surfboard according to claim 4 , wherein both ends of the intermediate portion are integrally formed with the extension piece of one of the two top wall connecting pieces of the first connecting portion and the extension piece of one of the two bottom wall connecting pieces of the second connecting portion on a same side of the first connecting portion and the second connecting portion, respectively.

6. The surfboard according to claim 4 , wherein respective ends of the intermediate portion are integrally formed with the extension piece of one of the two top wall connecting pieces of the first connecting portion and the extension piece of one of the two bottom wall connecting pieces of the second connecting portion on the opposite sides of the first connecting portion and the second connecting portion, respectively.

7. The surfboard according to claim 1 , further comprising an auxiliary reinforcing piece configured to be arranged between a reinforcing piece and one of the first connecting portion and the second connecting portion, the auxiliary reinforcing piece covering the one of the first connecting portion and the second connecting portion.

8. The surfboard according to claim 7 , wherein the auxiliary reinforcing piece covers a gap between at least one of:
the two top wall connecting pieces of the first connecting portion; and
the two bottom wall connecting pieces of the second connecting portion.

9. The surfboard according to claim 7 , wherein the reinforcing piece is disposed on and covers the auxiliary reinforcing piece and one of the first connecting portion and the second connecting portion.

10. The surfboard according to claim 1 wherein:
the first end of the intermediate portion is integrally formed with the extension piece of one of the two top wall connecting pieces, and the second end of the intermediate portion is sandwiched between the opposite two bottom wall connecting pieces; or
the first end of the intermediate portion is integrally formed with the extension piece of one of the two bottom wall connecting pieces, and the second end of the intermediate portion is sandwiched between the opposite two top wall extension pieces.

11. The surfboard of claim 1 , wherein the intermediate portion is formed from a single piece of material.

12. A surfboard, comprising:
a first air chamber and a second air chamber; and
a partition arranged between the first air chamber and the second air chamber, the partition comprising:
a first connecting portion connected to a top wall of the first air chamber and to a top wall of the second air chamber, the first connecting portion comprising two top wall connecting pieces, each of the two top wall connecting pieces comprising an extension piece extending between the first air chamber and the second air chamber;
a second connecting portion connected to a bottom wall of the first air chamber and to a bottom wall of the second air chamber, the second connecting portion comprising two bottom wall connecting pieces, each of the two bottom wall connecting pieces comprising an extension piece extending between the first air chamber and the second air chamber;
an intermediate portion extending between the first connecting portion and the second connecting portion; and
wherein:
the second air chamber is arranged around the first air chamber; and
a first end of the intermediate portion is integrally formed with one of the extension pieces of the two top wall connecting pieces and is connected to the other extension piece of the two top wall connecting pieces; and/or
a second end of the intermediate portion is integrally formed with one of the extension pieces of the two bottom wall connecting pieces and is connected to the other extension piece of the two bottom wall connecting pieces.
