Abstract
A portable, flexible cushion disclosed utilizes layers of different foam plastic materials secured together at contacting faces. The cushion combines closed cell and open cell foam plastic material features and a hinged construction providing reversibility and can be used in right angle and flat end to end applications. Optionally, vibrators are received in openings in the panels for therapeutic purposes. Different combinations of the closed and open cell materials are particularly suitable for wet or dry applications.
Claims24
A portable flexible cushion for user body comfort and user body stimulation suitable for both wet and dry use comprising:
- first and second panels connected by a hinge for relative pivotal movement,
- each of said panels having a first layer of closed cell foam plastic material impervious to a liquid so as to float in the liquid, said layer of closed cell foam plastic material being a continuous unitary piece for both of said first and second panels,
- said hinge including a strip of flexible material secured along one face intermediate the ends of said continuous unitary piece of closed cell plastic material and at least one of said panels having a second layer of open cell foam plastic material capable of absorbing a liquid and releasing a liquid in response to a surface pressure applied thereto, said second layer being superposed on and secured to said first layer of one of said panels at adjacent faces a pocket formed between said layer of open cell foam plastic material and said closed cell foam plastic material of said one panel, said pocket having an access opening.
A portable flexible cushion for body comfort and stimulation particularly suitable for dry situations comprising:
- first and second cushion panels connected by a hinge for pivotal movement so that either of said panels may pivot substantially 360 degrees relative to the other so as to be reversible and fold back against one another to a folded-up position and be set at any angular position,
- said first panel having first and second layers of a closed-cell foam plastic material, said first and second layers being a continuous single piece of material that is folded back on itself forming a looped end section adapted to receive a vibrator to transmit vibrations via an associated layer to the user and a third layer including an open cell foam plastic material secured between said first and second layers,
- said second panel having a layer that is an extension of said second outer layer and a layer of open cell foam plastic material,
- said hinge including a pair of flexible hinge strips secured along the inside to said first and second panels and a flexible tube sandwiched at an intermediate position between said hinge strips, a flexible cord extending through said tube having extensions beyond said tube for tying said panels to a support.
A portable flexible cushion for body comfort and stimulation particularly suitable for wet situations comprising:
- first and second cushion panels connected by a hinge for pivotal movement so that either of said panels may pivot substantially 360 degrees relative to the other so as to be reversible and fold back against one another to a folded-up position and be set at any angular position,
- said first panel having first and second layers of an open cell foam plastic material, said first and second layers being a continuous single piece of material that is folded back on itself forming a looped end section adapted to receive a vibrator to transmit vibrations via an associated layer to the user and a third layer including a closed-cell foam plastic material secured between said first and second layers,
- said second panel having a layer that is an extension of said third layer and a layer of open cell foam plastic material,
- said hinge including a pair of flexible hinge strips secured along the inside to said first and second panels and a flexible tube sandwiched at an intermediate position between said hinge strips, a flexible cord extending through said tube having extensions beyond said tube for tying said panels to a support.
A portable flexible cushion for user body comfort and user body stimulation suitable for both wet and dry use comprising:
- first and second panels connected by a hinge for relative pivotal movement,
- each of said panels having a layer of closed cell foam plastic material impervious to a liquid so as to float in the liquid, and
- at least one of said panels having a layer of open cell foam plastic material capable of absorbing a liquid and releasing a liquid in response to a surface pressure applied thereto, said second layer being superposed on and secured to said first layer of one of said panels at adjacent faces,
- said hinge including a pair of flexible hinge strips, said hinge strips being secured along inside adjacent contacting faces of said first and second panels,
- one of said hinge strips having a folded back end section to provide a double thickness.
A portable flexible cushion for user body comfort and user body stimulation suitable for both wet and dry use comprising:
- first and second panels connected by a hinge for relative pivotal movement,
- each of said panels having a layer of closed cell foam plastic material impervious to a liquid so as to float in the liquid, and
- at least one of said panels having a layer of open cell foam plastic material capable of absorbing a liquid and releasing a liquid in response to a surface pressure applied thereto, said second layer being superposed on and secured to said first layer of one of said panels at adjacent faces,
- said first panel having first and second layers made of a continuous single piece folded back on itself to form an open-ended looped end section adapted to receive a vibrator to transmit vibrations via an associated layer to the user.
