FLOATING BODY
Abstract
A floating body upon which swimmers may rest has an inner
central chamber open at its bottom to let in surrounding water, a
valved conduit leading from the upper end of said chamber to the
outside for letting a swimmer control the amount of water and air
in said chamber and thus the amount of submergence of the body and
a bolt extending through the center of the bottom of the body to
allow an anchor to be attached thereto to allow the rotation of the
body in the water, while the remainder of said body is enclosed
providing a floatation chamber.

Claims
I claim:
1. A floating body, preferably for bathing purposes comprising a
hollow cylindrical body having a partition wall which divides the
interior of said body into an outer annular section and an inner
central section, said inner central section having in its lower
portion at least one opening through which water may enter into
said section and that the upper portion of said inner central
section having an opening to the atmosphere and a manually operable
control valve for controlling said inner central section upper
opening in order to vary the draught of the floating body.
2. A floating body as claimed in claim 1, wherein said body
includes an outer receptacle and an inner receptacle, the latter
having the shape of a frustrum of a cone having a top wall facing
upwardly, said inner receptacle being positioned centrally relative
to said outer receptacle and being sealingly secured to the same
such that an outer annular section and an inner section are
obtained, a curved cover, the upper portion of said inner
receptacle serving as a support for the central portion of said
curved cover the outer portion of which is supported by the upper
edges of said outer receptacle.
3. A floating body as claimed in claim 2, characterized in that the
upper portion of said inner section communicates with the free air
a conduit one end of which opens into said inner section at the
upper portion of the same and the opposite end opens into a said
manually operable control valve mounted at the periphery of said
floating body, immediately below the cover of said body.
4. A floating body as claimed in claim 3, characterized in that a
downwardly projecting securing element attached to said inner
receptacle and having its free end connected to the bottom of said
outer receptacle in such manner that said inner receptacle is held
against said bottom of said outer receptacle, sealing elements
being arranged to sealingly separate the interior of said inner
receptacle from the portion of said outer receptacle which
surrounds said inner receptacle, whereby said securing element
protrudes through the bottom of said outer receptacle and rotatable
securing means is connected to the protruding end of said securing
element.
5. A floating body as claimed in claim 4, characterized in that the
securing element is fastened to the top wall of said inner
receptacle.
Description
This invention refers generally to floating bodies and more
specifically to a floating body, which is intended to be used in
the sea, in swimming pools and similar places where an artificial
island, where swimmers may rest, is desired.
Floating bodies containing encapsuled air volumes and/or floating
elements are known per se but they are difficult to use owing to
their tendency to tilt. The difficulty of embarking such floating
bodies is further increased by the fact that their upper supporting
surface is located at a considerably higher level than the level of
the surrounding water.
The main object of the invention is to eliminate the disadvantages
referred to and to provide a floating body, which may rotate about
a vertical axis, thus enhancing the amusement possibilities of the
floating body. Further advantages and characteristics will be
apparent from the following specification with reference to the
accompanying drawing, which illustrates a preferred embodyment of
the invention.
FIG. 1 shows the new floating body in a perspective view and
FIG. 2 is a central section through the floating body according to
FIG. 1.
The floating body according to the drawing comprises an outer
receptacle 1, which is preferably made from plastic, reinforced
material. Resting against the bottom surface 2 of said outer
receptacle is a flange and sealing elements portion 3 of an inner
receptacle 4, the bottom 5 of which, faces upwardly and serves as a
support for a cover 6. Also this cover and the inner receptacle may
be made from reinforced plastic material, and the cover may be
secured to the receptacle by means of screws or the like /not
shown/ at the periphery of the cover. Also in the central portion
the cover may be secured to the bottom 5 of the inner receptacle.
From the bottom 5 of the inner receptacle projects downwardly a
fastening element 7, which with its free end penetrates a hole 8 in
the bottom surface of the outer receptacle. Said fastening element
may be in the shape of a bolt having flanges and/or nuts 9, by
means of which the inner receptacle may be pressed against the
bottom of the outer receptacle. At its free end the fastening
element 7 is provided with a rotatable securing means 10 for a rope
or the like for anchoring the floating body. A conduit 11 which
opens into the upper portion of the receptacle 4 extends preferably
radially outwardly and ends in a manually operable control valve 12
for permitting air to leave the inner receptacle 4. The inner and
outer receptacles form together an outer space 13, which contains
air and floating elements 14 like pieces of sponge or cellular
material and an inner space 15, which contains a certain amount of
air. By means of holes 16 arranged in the bottom of the receptacle
1 water may enter into the space 15.
When the floating body is loaded and the control valve 12 is held
open water will penetrate into the inner space 15 and when the
control valve is closed said water amount will remain in the inner
space 15 and will stabilize the floating body and maintain its
draught. Thus it is possible to control the stability and draught
of the floating body such that it will always be easy to go on
board on the floating body and thanks to the water amount in the
inner space 15 the draught of the floating body may be very deep,
which contributes in making the floating body easy to go on board
on. As will be apparent from the drawing, the floating body may be
manufactured in the shape of a circular or rotational body and as
the body is anchored at the center the floating body may be
rotated, which makes a very amusing effect and inspires to water
games. In contradistinction to known floating bodies this floating
body may be anchored with a single, slack rope.
The invention is not limited to the embodyment illustrated but may
be varied within the scope of the appended claims.
