DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
This invention relates to a pillow and in particular to a bed pillow.
BACKGROUND OF THE INVENTION
Many attempts have been made to make pillows adjustable in thickness so that a pillow can be easily converted to suit the requirements of individual users. Such pillows have met with varying degrees of success and a pillow proposed by us in our Australian Patent No. 650051 includes a number of different sections that sit on top of one another which can be removed to change the thickness or height of the pillow as well as the pillow contour.
SUMMARY OF THE INVENTION
This invention provides an alternative pillow and alternative manner of forming the pillow.
The invention may be said to reside in a pillow including: surfaces, the insert being removable to decrease the height of the pillow. part of the pillow and is not merely a separate slab or section which is placed on or below another section of the pillow. In order to reduce the thickness of the pillow the insert section is merely removed from the interior of the pillow thereby reducing its thickness or height.
The invention may also be said to reside in a method of manufacturing a pillow including the steps of: having an upper surface and a lower surface and a pair of ends; intermediate point within the pillow body; and surfaces so that the height of the pillow can be reduced by removing the removable insert from the pillow body.
Preferably the upper and lower surfaces have a corrugated or battlement like shape. However, in other embodiments they could be smooth surfaces.
Preferably the surfaces are contoured to provide a pair of ridges separated by a valley.
BRIEF DESCRIPTION OF THE DRAWINGS
A preferred embodiment of the invention will be described, by way of example, with reference to the accompanying drawings in which:
FIG. 1 is a perspective view of a pillow embodying the invention;
FIG. 2 is a view along the line II--II of FIG. 1;
FIG. 3 is a view along the line III--III of FIG. 1;
FIG. 4 is a view of the pillow similar to FIG. 2 but with an insert portion removed;
FIG. 5 shows the method of cutting the pillow of FIG. 1 from a body of material; and
FIG. 6 is a detailed view of the circled portion A of FIG. 2 but showing a different surface profile.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
With reference to FIG. 1 a pillow 10 is shown which has an upper surface 12 and a lower surface 14. Rounded side portions 16 and 18 join the upper surface 12 to the lower surface 14.
The upper and lower surfaces 12 and 14 are contoured and have a pair of ridges 20 which are separated by valleys 22.
As best shown in FIGS. 2 and 3 the pillow 10 is provided with an internal insert portion 30 which is cut from the pillow 10 and which is removable from the pillow 10 by drawing the insert out of the pillow 10 in a direction of arrow B or arrow C in FIG. 1.
When the insert 30 is withdrawn from the pillow 10 the pillow 10 takes on a thinner or reduced height profile as shown in FIG. 4 to thereby enable the height or thickness of the pillow to be reduced at will by removing the insert portion 30.
The pillow of FIGS. 1 to 4 is preferably made by cutting the pillow from a block of material in a single cycle with a conventional cutting tool. Preferably the block is of foam material and the cutting tool is a saw or blade for cutting foam which is under computer control.
The pillow is cut from the material by cutting the block of material shown in FIG. 5 in the following manner:
The block of material 50 is firstly cut from a mid-point 52 into the block of material to a point 53. The lower surface 14 is then cut from point 53 to point 54. The side surface 18 is then cut from point 54 to point 56. The upper surface 12 is then cut from point 56 to point 58. The other side surface 16 is cut from point 58 to point 60. The remainder of the bottom surface 14 is cut from point 60 to point 62. The cutting saw then makes a cut inwardly from point 62 to point 64 and then continues to point 65, to point 68, to point 70 to point 72, and then back to point 64 a
