Swimming equipment improvement

Abstract

An improved structure of swimming equipment includes a swim fin shoe body, a holder, an assembling slot and a straight swim fin board. Two ends of the swim fin shoe body are provided with a tip and a heel respectively. The tip of the swim fin shoe body extends at an angle towards the front and underside of the swim fin shoe body to form the holder, and the front end of the holder is provided with the assembling slot. Two ends of the straight swim fin board are provided with a paddling section and a detachable assembling section assembled in the assembling slot. The assembling section and paddling section form a straight pattern jointly, so that the straight swim fin board tilts towards the front and underside of the swim fin shoe body along with the holder.

DETAILED DESCRIPTION OF THE INVENTION

(7) FIG. 2 discloses the implementation mode of the present invention. Said figure describes the swimming equipment improvement of the present invention, comprising a swim fin shoe body 1, a holder 11, an assembling slot 12 and a straight swim fin board 2. The swim fin shoe body 1 has a top surface 101 and a sole 102, and a tip 103 and a heel 104 are located in both ends of swim fin body 1 respectively.

(8) In the preferred embodiment adopted, the tip 103 of the swim fin shoe body 1 tilts and extends towards the front and underside of the swim fin shoe body 1 to form the holder 11, and the front end of the holder 11 is provided with the assembling slot 12, so that the included angle from the holder 11 and assembling slot 12 to the sole 102 of the swim fin shoe body 1 is 5 to 30, and the slot opening 121 of the assembling slot 12 opens towards the front of the holder 11. Two ends of the straight swim fin board 2 are provided with a paddling section 21 and a detachable assembling section 22 assembled in the assembling slot 12 respectively. The assembling section 22 and paddling section 21 form a straight pattern jointly.

(9) The assembling section 22 of the straight swim fin board 2 can be inserted in the assembling slot 12 through the slot opening 121 at the front end of the holder 11, and the assembling section 22 of the straight swim fin board 2 is fixed to the assembling slot 12 of swim fin shoe body 1 with screws, tenons or similar structures, so that the straight swim fin board 2 tilts towards the front and underside of the swim fin shoe body 1 along with the holder 11, the included angle between the straight swim fin board 2 and the sole 102 of the swim fin shoe body 1 is 5 to 30. Therefore, the tilt angle between the straight swim fin board 2 and swim fin shoe body 1 conforms with human engineering of kicking swim fin, and the structure of the straight swim fin board 2 is simplified, saving the production cost, and it is easy to assemble the swim fin shoe body 1 and straight swim fin board 2, favorable for carrying multiple straight swim fin boards 2 to the diving site. In addition, the straight swim fin board 2 is assembled in the front of the diver's sole, not trampled under the sole, it is unlikely to be broken. When the straight swim fin board 2 is to be changed by another material, the assembling section 22 of the straight swim fin board 2 can be drawn out of the assembling slot 12 easily, so as to disassemble the straight swim fin board 2 rapidly.

(10) FIGS. 3 to 5 show in a feasible embodiment, the slot opening 121, 122 of assembling slot 12 of the holder 11 can open towards the front and underside of the holder 11.

(11) FIG. 6 shows in a modified embodiment, the assembling slot 12 of the holder 11 is provided with a forward slot opening 121, the downward slot opening 122 of the assembling slot 12 is omitted (as shown in FIGS. 4 and 5), and there is a wall 123 for closing the slot opening 122 in the position of the assembling slot 12 facing towards the underside of the holder 11.

(12) In comparison to previous techniques, the present invention has the following advantages.

(13) First, the holder 11 and assembling slot 12 are located in the front end of tip 103 of the swim fin shoe body 1 at an angle, so that the straight swim fin board 2 is free of the bending section of the known bending swim fin board, the overall length of the straight swim fin board 2 can be shorter than the known bending swim fin board, enhancing portability.

(14) Next, as the straight swim fin board 2 is a straight form composed of the assembling section 22 and paddling section 21, the overall structure is flat and simple, the structural complexity is reduced a lot, and the production cost is reduced.

(15) Next, it is easy to assemble the straight swim fin board 2 with the assembling slot 12 of holder 11, the straight swim fin board 2 can be assembled or disassembled easily, favorable for trips.

(16) Next, as the straight swim fin board 2 and swim fin shoe body 1 can be assembled easily, multiple straight swim fin boards 2 of different materials (e.g. plastic, glass fiber and carbon fiber boards) and rigidities can be carried simultaneously, so as to choose the straight swim fin board 2 of any material and rigidity according to the flow intensity on the diving site (e.g. lakeside, seaside), and the assembly can be done rapidly on the diving site.

(17) Finally, as the assembling section 22 of the straight swim fin board 2 is located in the front end of tip 103 of the swim fin shoe body 1, whereas the bending section of the known bending swim fin board is located under the diver's sole, if the straight swim fin board 2 made of glass fiber or carbon fiber material is used, the straight swim fin board 2 and assembling section 22 will not be broken by trampling.

(18) The above is only the preferred embodiment of the present invention, it may not limit the applicable range of the present invention, any changes and modifications which can be done apparently by the persons familiar with this industry shall be regarded as substantial content not departing from the present invention.
