摘要： PROBLEM TO BE SOLVED: To provide a bedding excellent in heat insulating and heat retaining properties and suitable for a person who is sensitive to cold. SOLUTION: A heat insulating sheet 7 where a reflection jacket layer is formed on the front surface of a knit and an air including heat insulating fiber layer is integrally fixed in the knit is fixed in a lower part 6 at the quilt leg side which includes a part for the almost lower body of a sleeping person between the front side cloth and the rear side cloth of bedding 1. Moreover, the heat insulating sheet 7 is fixed to the lower part 6 at the blanket leg side which brought into contact with the front side cloth in a feather quilt where feathers are sealed inside a feather storing chamber constituted of the front side cloth, the rear side cloth and a gusset cloth whose upper and lower end edges are sewed with the both cloths. In the feather quilt, an area in a part formed by the front side cloth or the rear side cloth of the feather storing chamber positioned in the center part of the feather quilt is made to be larger than the area of a part which is formed by the front side cloth or the rear side cloth of the feather storing chamber positioned in the peripheral edge part of the quilt and also a feather storing quantity per unit area in the feather storing chamber positioned in the feather center part is made to be larger than the quantity per unit area in the feather storing chamber positioned in the peripheral part of the feather quilt.

摘要： PROBLEM TO BE SOLVED: To allow a large elastic deformation, compared with the size of a spring by differing the diameter of an annular member from the adjacent annular member, providing a limiting plate for preventing the mutual interference of elastic connecting members situated on both sides thereof. SOLUTION: When an excessive compression load is worked, each curved part 43, 43 of both upper and lower elastic connecting parts 4, 4 is brought into contact with an annular member 2 in the center, and the other end 42, 42 of each elastic connecting part 4, 4 is brought into contact with each of flat upper and lower surfaces of a limiting plate 21, whereby the elastic deformation exceeding it is limited. Thus, even if a spring 1 is three-dimensionally inclined by adding a bending or twisting to the other end parts 42, 42 of each elastic connecting member 4, 4, the spring 1 can be prevented from being laid in unstable support state or broken by the contact of each part of the other end parts 42, 42 or the outside and inside shifting thereof, and a stable support state can be provided.

摘要： PROBLEM TO BE SOLVED: To provide a spring having light weight and quietness with good productivity, and capable of permitting a large amount of elastic deformation as compared with a size of the spring. SOLUTION: In a spring 1 forming a total unit integrally by a synthetic resin material, comprising a plurality of annular members having a suitable space to be arranged in parallel with the same axial center and elastic connection members connecting mutually the annular member in a plurality of parts, arranging the elastic connection member along a virtual cylindrical surface formed by each annular member, and forming turned U shape cured in a peripheral direction of the annular member, a diameter of the annular member is set so as to be different mutually between the adjacent annular members 2, 3, one end part and the other end part of the elastic connection member 4 connecting these members are prevented from overlapping in an axial direction. In the annular member 2, 3, in a position overlapping with a curved part of its adjacent elastic connection member 4 in an axial direction, a recessed part is formed. Further, one end part 41 and the other end part 42 of the elastic connection member 4 are arranged to be displaced in a peripheral direction of the annular member, length of an arm in a side of one end part 41 and the other end part 42 of the elastic connection member is made different, also in the annular member connected to the longer arm, a recessed part 33 is formed.

摘要： PROBLEM TO BE SOLVED: To numerically express the positional relation between the neck part and the occipital region in a standing or a seated posture and selecting a pillow suited to each person, one of good sleeping conditions by providing a measuring body having a measuring point in the tip part of a vertical base board and an expression means of the horizontal and vertical distance from a reference point to a measuring point on the vertical base board. SOLUTION: At first, a person 9 to be measured takes a natural seated posture and tightly sticks the back face to a vertical base board 3 and a measurer confirms the posture that the eyes and the ear holes are coincided with a mark line 82 of the head part posture regulating member 8, a measuring body 6 is moved along the neck and the head part of the person 9 to be measured in this state, and the horizontal distance (x) and the vertical distance (y) from the reference point O to a measuring point P are measured by a measuring value expression means 7. The height and the positional relation of the human body neck part and the occipital part and the curved shape from the neck part to the occipital part can be numerically expressed with the human body back face in the natural seated posture set to the reference face (x0) by the obtained measurement value of the horizontal and vertical distances (x), (y) so that a pillow suited to an individual person can be selected based on such objective numerical values.
