BACKGROUND OF THE INVENTION
The present invention relates to a diving float, especially to a portable inflatable diving float.
Free-diving is one of the most popular recreational activities today. On attractions near the coast, free-divers carry inflatable diving floats with them. Although a conventional inflatable diving float (float body) can be carried on the user's back (such as the float body 2 shown in FIG. 10), the horizontal length/diameter of the float body is about 70 centimeters (as the arrow in FIG. 10 indicates). The length/diameter is larger than the width of the user's back so that the user is unable to be moved freely in the crowded area (such as prosperous markets) or in a cramped space (such as a bus compartment). Since the conventional inflatable diving float (float body) has the shortcoming of low portability, there is room for improvement and there is a need to provide a novel portable inflatable diving float.
SUMMARY OF THE INVENTION
Therefore it is a primary object of the present invention to provide a portable inflatable diving float in which a left folding area and a right folding area are respectively formed on the left side and the right side of a horizontal portion of a float body thereof. After being folded toward the middle of the float body, the left folding area and the right folding area are connected by a first connection member and kept in the folded state. Thereby a flat body formed after deflation of the float body is folded into a backpack body with smaller area. Moreover, at least one strap member is disposed between the top and the bottom ends on a front side or a back side of the float body so that users can carry the backpack body on their back with them. Thereby the poor portability problem of the conventional portable inflatable diving float (float body) has been solved effectively.
In order to achieve the above object, a portable inflatable diving float according to the present invention includes a float body able to be blown up. After being deflated, the float body becomes a flat body. The flat body is defined to include a horizontal portion, a vertical portion and a middle portion which is an intersection of the horizontal portion and the vertical portion. The left side and the right side of the horizontal portion of the float body are symmetrical to each other. A left folding area and a right folding area are respectively formed on the left side and the right side of the horizontal portion of the float body for being folded toward the middle portion. The horizontal length of the horizontal portion is reduced when the left folding area and the right folding area are simultaneously folded toward the middle portion and kept in the folded state. After the left folding area and the right folding area being folded over the middle portion, a left edge portion of the left folding area and a right edge portion of the right folding area are connected by a first connection member. Thereby the left folding area and the right folding area are kept in the folded state over the middle portion. Thus the flat body formed after deflation of the float body further becomes a backpack body with smaller area. At least one strap member is connected between the top end and the bottom end on a front side or a back side of the float body. Thus users can carry the backpack body formed by the folded flat body on their back with them by the strap member.
Preferably, the strap member includes two straps extending from the top end to the bottom end of the backpack body and arranged symmetrically to each other. Thereby a user can carry the portable inflatable diving float on the back by the two straps which go over the left should and the right shoulder of the user respectively.
Preferably, when the left edge portion of the left folding area and the right edge portion of the right folding area are connected by the first connection member and kept in the folded state, the left edge portion of the left folding area and the right edge portion of the right folding area can be against each other, arranged symmetrical to and spaced apart from each other, or overlapped with each other.
Preferably, the first connection member can be designed into different types such as a side release buckle, a hook-and-loop fastener, or a button.
Preferably, the respective types of the first connection member can be formed by a male part and a female part respectively arranged at the left edge portion of the left folding area and the right edge portion of the right folding area.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
In order to learn structure and technical features of the present invention, please refer to the following embodiments together with the related figures.
Refer to FIG. 1-9 and FIG. 11-21, two embodiments of a portable inflatable diving float according to the present invention are revealed. The portable inflatable diving float 1 of the present invention includes a float body 10 which is able to be blown up and provided with at least one inflation valve 20 and at least one deflation valve 30. The inflation valve 20 enables users to blow up (as the arrow A in FIG. 3 indicates) the inflatable float body 10, as shown in FIG. 1-3 and FIG. 15 while the deflation valve 30 allows users to release gas from the inflatable float body 10 (as the arrow B in FIG. 4 indicates) so that the inflatable float body 10 becomes a flat body 10a, as shown in FIG. 4-6, FIG. 16 and FIG. 17. Refer to FIG. 5 and FIG. 16, the flat body 10a is defined to include a horizontal portion 11, a vertical portion 12, and a middle portion 13 which is an intersection of the horizontal portion 11 and the vertical portion 12. The left side and the right side of the horizontal portion 11 of the float body 10 are symmetrical to each other, but not limited.
Refer to FIG. 5 and FIG. 16, a left folding area 14 and a right folding area 15 are respectively formed on the left side and the right side of the horizontal portion 11 of the float body 10 for being folded toward the middle portion 13 (as shown in FIG. 6 and FIG. 17). The horizontal length of the horizontal portion 11 is reduced when the left folding area 14 and the right folding area 15 are simultaneously folded toward the middle portion 13 and kept in the folded state.
As shown in FIG. 6-8, FIG. 11-14 and FIG. 17-21, after the left folding area 14 and the right folding area 15 being folded over the middle portion 13, a left edge portion 141 of the left folding area 14 and a right edge portion 151 of the right folding area 15 are connected by a first connection member 40. Thereby the left folding area 14 and the right folding area 15 are kept in the folded state over the middle portion 13. Thus the flat body 10a formed after deflation of the float body 10 further becomes a backpack body 10b with smaller area.
As shown in FIG. 7, FIG. 8, FIG. 13, FIG. 14, FIG. 18, and FIG. 19 at least one strap member 50 is connected between the top end and the bottom end on a front side or a back side of the float body 10.

The first connection member 40 can be designed into different types such as a side release buckle 40a (as shown in FIG. 8, FIG. 11, FIG. 12, FIG. 14, and FIG. 19), a hook-and-loop fastener 40b (as shown in FIG. 20), or a button 40c (as shown in FIG. 21). The respective types of the first connection member 40 can be, but not limited, formed by a male part and a female part respectively disposed on the left edge portion 141 of the left folding area 14 and the right edge portion 151 of the right folding area 15. The side release buckle 40a, the hook-and-loop fastener 40b, or the button 40c are generally known to people skilled in the art so that they are not described in details and shown in figures.
Refer to FIG. 5 and FIG. 12, a bottom side of the middle portion 13 of the float body 10 can be folded upward to form a bottom folding area 16. When the bottom folding area 16 has been folded toward the middle portion 13, the vertical length of the vertical portion 12 is reduced.
Refer to FIG. 5, FIG. 12 and FIG. 14, after the bottom folding area 16 being folded to the middle portion 13, a bottom edge portion 161 of the bottom folding area 16 is connected to the middle portion 13 by a second connection member 60 so as to keep the bottom folding area 16 in the folded state over the middle portion 13.
Refer to FIG. 12 and FIG. 14, the second connection member 60 can be designed into different types such as a side release buckle 60a, a hook-and-loop fastener 60b, or a button 60c. The respective types of the second connection member 60 can be, but not limited, formed by a male part and a female part respectively arranged at the bottom edge portion 161 of the bottom folding area 16 and the middle portion 13. The side release buckle 60a, the hook-and-loop fastener 60b, or the button 60c are generally known to people skilled in the art so that they are not described in details and shown in figures.
