Benefits of technology

[0007]The object of the present invention is to provide a pillow having shape diversity, ease of forming, shape preservability and flexibility.
[0009]In a pillow of the present invention, a chip assembly comprises multiple chips that are connected together by means of a linear member having a rubber-like elasticity. Rubber-like elasticity is an elasticity exhibited by rubber and other similar substances. The substances having a rubber-like elasticity undergo substantially great alteration of shape under small stresses and quickly and substantially resume original shape. Accordingly, the user can easily adjust and change the shape of the pillow as he or she chooses by using hands or moving the head because the chip assemblies stretch, contract, bend or move. Even when the shape has changed, the pillow is impervious to losing its shape because the chips are connected together by the linear member. The user can always feel a soft touch because the chip assemblies stretch, contract, bend and move, that is to say, because the chips are not fastened, as the position and direction in which the weight of the neck and head applies load.

Problems solved by technology

Because, however, wooden balls are not bound but allowed to move freely, the pillow is ready to sag and lose its shape.
Therefore, this pillow lacks diverse formability and ease of forming.
However, this pillow lacks diverse formability because the pillow height is adjusted by moving the filler in the side edge parts to the headrest.
Besides, the hardness of the pillow changes with the height because the pillow becomes hard when the height increases.
Therefore, this pillow cannot provide softness irrespective of the shape and height thereof.
As described above, the conventional pillows have not sufficiently satisfied users' needs for the diversity and preservability of shape and the ease of forming.
Also, the conventional pillows have not provided the desired softness irrespective of the shape and height thereof.

example 1

[0029]The bag was 33 cm long, 48 cm wide and 6 cm high. The linear member was a rubber string prepared by covering polyurethane rubber with polyester knitting yarn. The rubber string was 1.2 mm diameter and 60 cm long. The rubber string had an elongation of 100 percent. The chips were made of cypress and had a diameter of 12 mm. Eighty pieces of chip assemblies were prepared by passing fifty-seven chips over each rubber string. The chip assemblies were mixed and stuffed in the bag, with a filling factor of 85 percent.

[0030]The popularly used pillow stuffed with buckwheat shells was used as the criterion for judging the shape diversity, ease of forming, shape preservability and flexibility and the pillow of the present invention described above was compared with commercially available low-resilience urethane foam, feather and beads pillows. Table 1 shows the results of the comparison. The pillow of Example 1 proved to excel the buckwheat shell pillow and the other commercially availa...

example 2

[0031]The bag was the same one as that used in Example 1. The chips were made of cypress and spherical in shape, having seven different diameters between 4 and 15 mm. The linear members were rubber strings similar to those used in Example 1, having lengths of 30, 60 and 120 cm. The rubber strings had an elongation of 100 percent. Chip assemblies were prepared by passing chips throughout the entire length of each rubber string. Twenty-one types of chip assemblies totaling 106 pieces were prepared by using chips of seven different diameters and rubber rings of three different lengths. Randomly mixed chip assemblies were stuffed in the bag with a filling factor of 85 percent. Table 2 shows the combinations of the chips and rubber strings.

example 3

[0033]The bag and chip assemblies were the same as those used in Example 2. However, the chip assemblies were connected into a loop form and randomly stuffed in the bag. While the loops were 15, 30 and 60 cm in length, the filling factor was 85 percent.

[0034]The pillow prepared as described above was compared with the conventional pillow stuffed with buckwheat shells in terms of the shape diversity, ease of forming, shape preservability and flexibility and the pillow of the present invention described above was compared with commercially available low-resilience urethane foam, feather and beads pillows. Table 1 shows the results of the comparison. The pillow of Example 3 proved to excel the buckwheat shell pillow and the other commercially available pillows in all respects.

[0035]The present invention is not limited to the examples described above. For example, chip assemblies of wooden and synthetic resin chips may be stuffed together. Aromatic materials, such as lavender, rose and ...

Abstract

A pillow comprising a bag and a large number of chips in the bag, wherein multiple chips are connected together to form a chip assembly by means of a linear member comprising a thread or a string having a rubber-like elasticity passed through a through-hole provided in the chips, and multiple chip assembly are stuffed in the bag.

Description

BACKGROUND [0001]The present invention relates to pillows that bring a pleasant sleep.[0002]Pillows are one of the important bedclothes. In order to obtain good sleep, the shape of pillows is a particularly important factor. Pillows are used by children to aged people, men and women, healthy and sick persons, and many others and the shape of pillows suited for individual users varies greatly from person to person. The shape of pillows depends on the size of the head and neck of users, position of the sleeping posture of users, position of the head with respect to the pillow, and other factors. The posture of sleepers and the position of the head change with tossing and turning. Accordingly, the shape of pillows is required to have variability to change their shape according to the condition of users, ease of forming into the desired shape, and the capability of preserving the formed shape without collapsing.[0003]In order to obtain a pleasant sleep, various contrivances have been ma...
