Claims
We claim:
1. A water bed, comprising spongy support means, flexible frame
means resting on the top surface of said support means and having a
recess in the top surface thereof, a flexible water holding means
having the top surface thereof approximately flush with the
uppermost portion of the top surface of said frame means and having
the bottom surface thereof in a shape matable with the shape formed
by said recess thereby preventing water from spilling onto the
surface upon which said support means rests should said water
holding means begin to leak due to the water holding capacity of
the recess, a second flexible water holding means removably
surrounding said support means, said frame means, and said water
holding means for preventing leaking water somehow spilling over
the uppermost portion of the top surface of said frame means from
leaking onto the surface upon which said support means rests, said
support means including a plurality of uniformly spaced vertical
holes therein, said support means having a water holding capacity
at least equal to that of said water holding means.
Description
This invention relates to an improved water bed. Conventional water
beds weigh approximately 2,000 pounds when they are filled with
water and no one is permitted to put them in a second floor
apartment due to the possibility of a leak and the weight. Also, a
conventional water mattress lies directly on the floor, and if a
frame is placed therearound, there is the high possibility of
banging oneself on the frame while lying on the mattress.
Accordingly, a primary object of this invention is the elimination
of water damage if the water mattress should develop a rip or
leak.
Another object of this invention is a safer bed minimizing accident
to the sleeper.
A further object of this invention is the provision of a bed
wherein the mattress need not be as thick when filled with water as
existing water mattresses.
The above and other objects of this invention will become apparent
to those skilled in the art after a consideration of a detailed
description of a preferred embodiment of this invention taken
together with the accompanying drawing wherein:
FIG. 1 is a top plan cut away view of the bed; and
FIG. 2 is a sectional view taken on line 2--2 of FIG. 1.
Referring in detail to the drawing, there is shown a base 10 of
thick spongy plastic material 12 having a plurality of vertical
holes 14 uniformly spaced therein. A frame 16 formed of a solid
slab of soft plastic material rests above base 10. Frame 16 curves
down from the perimeter thereof from the top surface 18 thereof to
a reduced thickness 20.
A water mattress 22 holding water therein and having a generally
flat top surface 24 and a bottom surface 26 having a shape mating
with the top surface 28 of frame 16 is placed within the recess
formed by reduced thickness 20 so that water mattress 22 is
surrounded along the perimeter thereof by perimeter 18 of frame 16.
Completely covering base 10, frame 16, and water mattress 22 is a
cover 30 having a waterproof coating 32 on the interior thereof. A
zipper 34 is located at one end of cover 30 so that it can be
removed for cleaning or any other purpose. It should be noted that
the covering may have any pleasing decorative effect printed on the
exterior.
If water mattress 22 should rip for any reason, the water would be
contained within the recess formed by frame 16. Any water spilling
over perimeter 18 of frame 16 would still be contained within cover
30.
While a preferred embodiment of this invention has been illustrated
and described, it should be understood by those skilled in the art
that many changes and modifications may be resorted to without
departing from the spirit and scope of the invention.
