2 Claims. (Cl. 9-347)
This invention relates to a ?oat, and more particularly
to a swimming pool or beach ?oat having an opening
therethrough and incorporating head rest and seat ele
ments. This application is a continuation of co-pending
application Serial No. 846,138, ?led October 13, 1959,
now abandoned for a Float for Use in Swimming Pools
and at Beaches, inventor William H. Bisch.
An object of the present invention is to provide a ?oat
having resilient and adjustable head rest means, such
‘Referring to FIGURE 3, the entire chamber 21 may
be ?lled with a suitable plastic foam, indicated at 22,
thereby making the body completely unsinkable. It is
also possible to form the body completely of a plastic
foam, such as expanded polystyrene, without employing
the solid plastic shells.
The seat 11 is illustrated to comprise a wide ?exible
strap which is bent into U-shape and suspended from the
center portions of arms 18. The strap is su?iciently long
that, when the occupant is seated thereon, his arms will
be at the proper elevation for support by the arms 18,
and his head and upper back will be at the proper eleva
tion for support by the upper portion of the head rest 13.
It is a feature of the inventIon that the seat strap 11 is
so secured to arms 18 that it may pivot about an axis
perp.ndicular to the major axis of the generally elliptical
body 10, and furthermore may be slid forward and back
ward on the arms. The seat may be readily mounted and
demounted without the necessity of tying and untying
means being simple and inexpensive, long lasting and 20 knots.
water resistant.
The above results are achieved by providing at each end
of the strap a keyhole slot 23, the narrow portion of each
slot being disposed adjac nt the extreme ends of the strap.
