Other phase change material (PCM) containers may have a side-to-side dimension or diameter of up to 50 millimeters. Some of the phase change material (PCM) containers may have a spherical shape having a diameter in a range of 15 to 25 millimeters. In some embodiments, the phase change material (PCM) containers may have a shape of an egg, a flattened sphere, or a cylinder.
- In certain embodiments, the second surface may have a plurality of upwardly extending fingers and a plurality of spaced apart pockets defined between the fingers. Some of the phase change material (PCM) containers may be disposed in the pockets of the second surface in the body of cushioning material. The phase change material (PCM) containers may have a first phase change temperature. Also, the phase change material (PCM) container on the second surface may have a second phase change temperature.

FIG. 3 is a cross-sectional view of an embodiment of a cushion with phase change material containers disposed on both surfaces; -
FIG. 4 is a cross-sectional view of an embodiment of a cushion with a plurality of spaced apart pockets; and -
FIG. 5 is a perspective view of an embodiment of a phase change material container in the form of a sphere with an outwardly extending ring at a centerline. - The present invention provides a cushion with discrete portions of phase change material (PCM) disposed on or in a cushion for providing a cooling effect when the cushion is used. The cushion may take a variety of forms, such as a mattress cover, mattress, seat cushion, pillow, or other types of cushions.
FIGS. 1 and 2 illustrate an embodiment of acushion 10 in the form of a pillow with apillow cover 12 that selectively covers a body of cushioningmaterial 14. In the illustrated embodiment, the cushion material is a body of foam material shaped as an egg-crate, also known as convoluted foam, type cushion.FIG. 2 provides a cross-sectional view across 2-2 ofFIG. 1 . As shown, the body ofmaterial 14 has abase portion 16 with a plurality of upwardly extendingfingers 18. The fingers are spaced apart by valleys orpockets 20 between thefingers 18. - In the illustrated embodiment,
PCM containers 22 are disposed in some or all of thepockets 20 between thefingers 18. Thepockets 20 andcontainers 22 are sized and shaped such that the containers nest in the bottom of eachpocket 20. ThePCM containers 22 may be adhesively or mechanically attached into thepockets 20. In some embodiments, a cover may restrainPCM containers 22. In the illustrated embodiment, thePCM containers 22 take the form of a small sphere with a plasticouter shell 24 filled with aphase change material 26. In an embodiment, thefingers 18 may have a height, from the bottom of apocket 20 to the top of afinger 18, in the range of 5 to 6 centimeters and thecontainers 22 may have a diameter in the range of 15 to 20 millimeters, with thepockets 20 sized to receive these containers. - In another embodiment, as shown in
FIG. 5 , thecontainers 22 may take the form of a sphere with an outwardly extendingring 50 at a centerline where two sphere halves are joined to form the sphere. In some embodiments, thering 50 may extend outwardly by approximately 3 millimeters. Thisring 50 may help in securing thecontainer 22 to the body of the cushion. The phase change material may have a phase change temperature in the range of 25° C. to 30° C., while some embodiments may have a phase change temperature of approximately 29° C. As known to a person of skill in the art, different PCM materials may be used. - For embodiments using PCMs in the above discussed temperature range, the PCM will solidify at room temperature and when placed in contact with the skin of a human, the person will feel cool. The PCM will increase in temperature until it reaches its phase change temperature, which may be close to a neutral skin temperature. The
cushion 10 may be designed such that when the cushion is in use, a user does not feel thePCM containers 22 as hard spots in the cushion. By selecting the type and durometer or Indentation Load Deflection (ILD) offoam material 14 for a given expected load, the cushion may be designed such that the fingers compress only enough for slight contact with the PCM containers. As shown inFIG. 1 , if the cushion is a pillow, lower ILD foam may be used to achieve this goal while if the cushion is a seat cushion, higher ILD foam may be required. As shown inFIG. 1 ,PCM containers 22 may be provided in all of thepockets 20 between the fingers except at the perimeter of the pillow. Alternatively, only certain pockets may be filled with PCM containers. Thecontainers 22 may all be the same or a mix of container sizes, shapes and PCM-fills may be used. In one non-limiting example, the containers near the center of the cushion use one phase change temperature of PCM and the containers near the perimeter use a second phase change temperature of PCM. In another non-limiting example, the containers towards one end or on one-half of the cushion are one phase change temperature and the other end or half are another phase change temperature. Alternatively, different shapes or sizes of PCM containers may be used in different areas to provide different temperature capacitances. - In other embodiments, all of the PCM containers may be filled with the same type and phase change temperature of PCM material. In some embodiments, different PCM containers may contain different type of PCM materials with different phase change temperatures. Also, not all pockets of a cushion may include PCM containers. In yet another embodiment, not all PCM containers may be of the same shape or size. In the illustrated embodiment, the
PCM containers 22 are all spheres. In other embodiments, the PCM containers may have other shapes e.g. egg shaped, flattened spheres, cylinders, and any other shape, which provides a desired performance. - The illustrated embodiment in
FIG. 1 is a one sided foam pad with fingers extending only from a single side with thebase portion 16 being flat on the other side. As shown inFIG. 3 , inother embodiments fingers 18 may extend from afirst surface 40 as well as asecond surface 60 of thecushion 10. The pockets in thefirst surface 40 andsecond surface 60 may or may not includePCM containers 22. In each case, thefingers 18 may be referred to as extending “upwardly” independent of the orientation of the cushion. For example,fingers 18 on thesecond surface 60 may extend “upwardly” with respect to the surface. Alternatively, this may be defined as outwardly from thesecond surface 60. In another embodiment, thefirst surface 40 may includePCM containers 22 with the first phase change temperature and thesecond surface 60 may includePCM containers 22 with the second phase change temperature. Other shapes and configurations of foam pads may also be used, such as molded foam. Further, thePCM containers 22 may be embedded in a cushioning pad with portions of cushioning material covering eachPCM container 22. ThePCM container 22 may be located to facilitate thermal transfer. In some embodiments, thePCM container 22 may have a side-to-side dimension of at least 5 millimeters. In other embodiments, the side-to-side dimension may at least be 10 millimeters, and in yet other embodiments, it may be at least 15 millimeters. - In some embodiments, as shown in
FIG. 4 , thefirst surface 40 and thesecond surface 60 of acushion 10 may have a plurality of spaced apart pockets 20. In other embodiments, only thefirst surface 40 or thesecond surface 60 may have a plurality of spaced apart pockets 20. Some or all of thepockets 20 of the first and/or second surface may have phasechange material containers 22 in a cube form. In some embodiments, not all phasechange material containers 22 may be of the same shape or size. The phasechange material containers 22 may have other shapes e.g. egg shaped, flattened spheres, cylinders, and any other shape, which provides a desired performance. In some embodiments, thepockets 20 may be of different shape to accommodate phasechange material containers 22 of different shapes and/or sizes. The phasechange material containers 22 may have different phase change temperatures. It is noted that in certain embodiments the PCM containers are disposed below the surface of the cushion. For example, inFIG. 4 thesurface 40 may be said to define a surface plane and thecontainers 22 are all spaced below this plane. - While the illustrated embodiment(s) uses foam as a cushioning material, other cushioning materials such as fibrous material, polyurethane, visco-elastic, latex, down, feathers or a mixture of materials may also be used. In one embodiment, a layer of one type of cushioning material may be combined with a layer of another type of cushioning material, e.g. a layer of down in combination with a sublayer of foam. A mix of foam materials may also be used, such as a denser base material and a lower durometer upper material for the
fingers 18, or vice versa. - It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. Thus, it is intended that the present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
