TECHNICAL FIELD
The invention relates to the field of flotation apparatuses.
BACKGROUND
My IL 254547 patent application discloses a continuous belt being spaced at the center thereof along a certain region.
However, the spacing at the center of the continuous belt does not sufficiently form an air space since the continuous belt attaches the spacing component. Further air spaces are formed below and above the certain region.
There is a long felt need to provide a solution to the above-mentioned and other problems of the prior art.
SUMMARY
A flotation apparatus, including:
- a water container!
- a continuous belt including two continuous straps sewn one to the other! - a spacing component disposed between said continuous straps, and including rotatable wheels being large and located for leaving air spaces therebetween.

DETAILED DESCRIPTION
Fig. 1 is a perspective view of a flotation apparatus according to one embodiment of the invention.
Fig. 6 is the perspective view of Fig. 1 from another angle of view. A flotation apparatus 10 according to one embodiment includes a water container 30 for containing water 12; and a continuous belt 17 deployed between a top pulley 23A and a bottom pulley 23B.
Fig. 2 is a front view of the continuous belt of Fig. 1.
Continuous belt 17 constitutes a sleeve including an external continuous strap 15A and an internal continuous strap 15A, sewn one to the other.
Straps 15A and 15B do not absorb water.
Referring again to Fig. 1, external continuous strap 15A and internal continuous strap 15B are sewn one to the other along knitting lines 50 A and 50B.
Since external strap 15A and internal strap 15B are knitted at knitting lines 50A and 50B shown in Fig. 1, external strap 15A and internal strap 15B be disposed apart from one another, thus forming a space 52 therebetween shown in Fig. 2.
Fig. 3 is a front sectional view of the flotation apparatus of Fig. 1.
A spacing component 54 is disposed between external strap 15A and internal strap 15B at a certain region 58 of continuous belt 17, being below the water level 56, for forming space 52.
Spacing component 54 includes a vertical cylinder 80 being hollow at the center 62 thereof, and a plurality of forks 64 extending outwards from vertical cylinder 80 and fixed thereto. Each of forks 64 includes a horizontal pivot 66, for rotating (70) a wheel 68 about the horizontal pivot 66.
External strap 15A and internal strap 15B attach spacing component 54. In spite of the attaching, wheels 68 of spacing component 54 are sufficiently large for leaving air spaces 72 vertically therebetween and thus between external strap 15A, internal strap 15B and spacing component 54.
Spacing component 54 between external strap 15A and internal strap 15B forms air spaces 72 tending to float (60) region 58 of continuous belt 17 towards above water level 56.
Region 58 of continuous belt 17 is pressed outwards by spacing component 54 and is pressed inwards by rings 20A,20B, etc. surrounding it.
Attaching wheels 21 and 22 disposed below and above spacing component 54 press external strap 15A towards internal strap 15B for not allowing the air enter therebetween.
However, some air enters between external strap 15A and internal strap 15B, even outside region 58. Bottom pulley 23B solves this problem by including a plurality of protrusions 74, for releasing (73) air confined between external strap 15A and internal strap 15B into (78) space 52.
Fig. 4 is a top sectional view of the spacing component and the belt surrounding it.
External strap 15A and internal strap 15B attach spacing component 54. However, wheels 68 of spacing component 54 are sufficiently large for leaving air spaces 72 horizontally therebetween and thus between external strap 15A, internal strap 15B and spacing component 54.
Fig. 5 is a side sectional view of the spacing component and the external strap covering it.
External strap 15 A (shown) and internal strap 15B (not shown) attach many wheels 68 forming an imaginary surface. However, wheels 68 of column 88A are disposed above and below wheels 68 of column 88B adjacent to column 88A, thus forming air spaces 72 therebetween. And wheels 68 of column 88B are disposed above and below wheels 68 of column 88C adjacent to column 88B, thus forming air spaces 72 therebetween.
In the same manner, wheels 68 of row 90A are disposed aside wheels 68 of row 90B adjacent to row 90A, thus forming air spaces 72 therebetween. And wheels 68 of row 90B are disposed aside wheels 68 of row 90C adjacent to row 90B, thus forming air spaces 72 therebetween.
Fig. 7 depicts another additional feature of the flotation apparatus of Fig. 1.
According to this embodiment, a vertical rod 94 extends downwards from spacing component 54 and is fixed thereto. Vertical rod 94 extends between wheels 21.
A horizontal rod 96 expands a small region continuous belt 17 and is fixed to the bottom of vertical rod 94 for encountering wheels 21 against rising of spacing component Numeral 10 denotes the flotation apparatus according to one embodiment of the invention!
