Pillows

#1. Field of the Invention

#This invention relates to improvements on pillows such that an improved pillow allows the neck (the vertebrae cervicales) of a person who is lying on a bed to be in a natural comfortable position. One variation of the improved pillow not only allows a user's neck to be in a natural comfortable position but also allows the user to reposition his/her head on the pillow easily. The other variation of an improved pillow allows a user to easily adjust its heights.

#2. Descriptions of the Prior Arts

#FIG. 1 is an isometric view of the first variation of an invented improved pillow.

#FIG. 2 is a sectional view of the invented device shown in FIG. 1.

#FIG. 3 is an isometric view of the second variation of an invented improved pillow.

#Three variations of the invented improved pillows are introduced herein in this specification.

#Referring to FIGS. 1 and 2, the first variation of an invented improved pillow 1 consists of a cushion 10, a curved plate 11, and a fabric 12. The cushion has thin center portion and two thick edge portions. The cushion is made of any suitable material such as cotton packs, foams, inflatable air bags, feathers, saw dusts, leaves, seeds, etc. The fabric is made of any suitable fabrics such as clothes, silks, leathers, etc. The curved plate is made of any suitable material such as plastics, metals, carbon fibers, glass fibers, etc. The cushion is on the concave side of the curved plate. The fabric encloses the curved plate and the cushion together. The curved plate provides a hard curved surface on the bottom of the improved pillow so that the improved pillow can rock easily on a bed. The curved plate creates the valley 13 and the peaks 14 for the improved pillow. The cushion at the valley of the improved pillow is thinner than that of the peaks.

#Referring to FIGS. 3 and 4, the second variation of an invented improved pillow 15 consists of a cushion 16, a curved plate 17, and a fabric 18. The cushion is made of any suitable material such as cotton packs, foams, inflatable air bags, feathers, saw dusts, leaves, seeds, etc. The fabric is made of any suitable fabrics such as clothes, silks, leathers, etc. The curved plate is made of any suitable material such as plastics, metals, carbon fibers, glass fibers, etc. The curved plate consists of two long curved plates 19 and 20 joined by at least one short curved plate 21 (only one shown in FIG. 4). Hinges 22 or glue-backed fabrics such as duct-tapes (not shown) makes the joining. The cushion is on the concave side of the curved plate. The fabric encloses the curved plate and the cushions together. The curved plate provides a hard curved surface on the bottom of the improved pillow. The curved plate helps to create a valley 23 and two peaks 24 for the improved pillow. The cushion at the valley of the improved pillow is thinner than that of the peaks.
