DESCRIPTION:

BRIEF SUMMARY
BACKGROUND OF THE INVENTION



Field of the Invention

This invention relates to improvements in or relating to pillows, particularly pillows formed of deformable moulded rubber or plastics material, and has as its object the provision of a pillow in a convenient and effective form. As used herein, the word `pillow` includes analogous items, such as cushions.


SUMMARY OF THE INVENTION

According to the present invention there is provided a pillow having upper and lower surfaces and at least one peripheral surface therebetween, at least one of the upper and lower surfaces having a central recessed area and respective first buttress portions at opposite sides thereof extending to said at least one peripheral surface, a pair of second buttress portions each extending to said at least one peripheral surface being disposed adjacent to and at respective opposite sides of one of the first buttress portions and spaced therefrom by respective further recessed areas extending from said central recessed area to said at least one peripheral edge.


BRIEF DESCRIPTION OF THE DRAWINGS

The invention will now be described, by way of example, with reference to the accompanying drawings, in which:
FIG. 1 is a top plan view of a pillow of the invention,
FIG. 2 is a cross-section on the line 2--2 of FIG. 1,
FIG. 3 is a schematic cross-section on the line 3--3 of FIG. 1,
FIG. 4 is a schematic cross-section on the line 4--4 of FIG. 1,
FIG. 5 is a schematic cross-section on the line 5--5 of FIG. 1, but showing an alternative underside form of the pillow,
FIG. 6 is a cross-section on the line 6--6 of FIG. 1,
FIGS. 7 and 8 are fragmentary enlarged cross-sections on the line 4--4 showing how the pillow alters its shape, in use,
FIG. 9 is a fragmentary view of the upper surface of the pillow schematically showing various areas defined thereon; and
FIG. 10 is a perspective view of an alternate embodiment of pillow formed of two parts secured together.


DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The pillow shown in the drawings is moulded from latex material or soft polyurethane either as one piece or in two identical, upper and lower halves, which are adhered together thereafter. The pillow is intended for use as an underpillow, with a top pillow of a user's own choice, i.e. foam, feather or man-made fibre filled, being used on top of the underpillow. Thus the user's head is only indirectly received on the underpillow.
The pillow is of generally rectangular shape in plan, having a straight rear edge or side surface 10, shorter straight transverse edge or side surfaces 11, 12 respectively, and a front edge or side surface 13 which is concave and thus defines a bright 14. The depth of the pillow is small as compared to the depth of conventional top pillows. The pillow has upper and lower surfaces 15, 16 respectively.
In alternative constructions of the pillow, the front and rear edges could both be straight, or both concave, and moreover either or both of the surfaces 15, 16 could be slightly convex instead of flat.
The pillow has front and rear rolls 17, 18 respectively, and also side rolls, of generally ovoid shape, i.e. with generally flattened upper and lower surfaces. Respective identical, central, large concave recessed areas 19, 20 are formed in the upper and lower surfaces and as the pillow is in fact symmetrical about a plane midway through it and parallel to upper and lower surfaces, i.e., through the front and rear rolls. The recesses overlie one another in a direction normal to the surfaces 15, 16. With the recessed areas 19, 20 the term `large` is used in comparison in surface area with the area of load (head) applied to the upper surface, in use.
On both its upper and lower surface the front roll 17 has a pair of symmetrically, longitudinally spaced apart minor recesses 21, 22 which effectively extend from the central recessed area to the front edge surface 13 of the pillow. The front roll is thus divided into a middle section or central buttress 23 and outer corner sections or major buttresses 24, 25 respectively.
