Abstract

(57) [Summary] [PROBLEMS] To support body pressure at many points and not to impede blood circulation and air permeability. SOLUTION: An arm plate 2 extends outward from a ridge line of a main body 1 of a polygonal cylinder whose top and bottom are open, and an outer plate 3 orthogonal to the extending direction of the arm plate is provided at an outer edge of each arm plate. The main body, the arm plate, and the arm plate are integrally formed of a resilient thermoplastic plastic. When this cushion material C is packed in a mattress or the like, it supports body pressure at many points, so there are many gaps between the body and the mattress, so that blood circulation,
It does not hinder air permeability, does not completely collapse even when body pressure is applied, and has a space between each other, so that it does not peel. It is also possible to wash the whole mattress.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a mattress and a pillow cushion material which is particularly suitable for a person who has been sleeping for a long period of time, such as the sick and bedridden elderly.

[0002]

[Prior art]

 For example, rubber foam rubber, plastic urethane foam and the like are used as mattress cushioning materials. In hospitals, straw is used. Mattresses using these cushioning materials support the back and legs of the user on the surface, so that there is no gap between the mattress and the back or legs. As a result, blood circulation and air permeability deteriorate, and the floor is easily rubbed.

In addition, since it does not absorb moisture such as sweat, except for the straw cushioning material, it is difficult to sleep especially in summer and easily emits an odor. In addition, since it cannot be washed in whole, it becomes unsanitary if used for a long time. There were further drawbacks that were heavy and unwieldy.

[0004]

[Problems to be solved by the invention]

 The problem to be solved by this invention is not to support the body pressure but to support it at many points, so as not to impede blood circulation and to ensure ventilation.

[0005]

[Means for Solving the Problems]

 In this invention, arm plates extend outward from the ridgeline of the body of the polygonal cylinder whose top and bottom are open, and at the outer edge of each arm plate, there is an outer plate orthogonal to the direction in which the arm plates extend. The main body, the arm plate, and the outer plate are provided integrally with a thermoplastic resin having elasticity.

[0006]

[Embodiment of the invention]

 The cushion material C will be described with reference to FIGS. 1 and 2. Reference numeral 1 denotes a main body of a regular hexagonal cylinder, whose upper and lower portions are open. Reference numeral 2 denotes an arm plate, which extends from the ridge line of the main body 1 with an equal length L2 on an extension of a straight line L1 connecting the center O of the main body 1 and the ridge line. Therefore, in the case of the illustrated example, the number of the arm plates 2 is six. Reference numeral 3 denotes an outer plate, which is provided on the outer edge of the arm plate 2 orthogonal to each arm plate 2. The width L3 of the outer plate 3 is equal, and both ends thereof and the length of the outer plate 3 are also equal.

In the illustrated example, L1 is 3 mm, L2 is 2.5 mm, L3 is 2.5 mm, and height L4 is 11 mm. Each thickness of the main body 1, the arm plate 2, and the outer plate 3 is 0.5 mm.

The cushion material C is formed by extruding thermoplastic resin such as polyethylene mixed with powder mainly composed of carbon having many fine pores such as charcoal and activated carbon, and then cutting the same. It can be easily formed at low cost. However, it is also possible to use only the thermoplastic plastic without mixing the powder.

Of course, the dimensions can be selected arbitrarily and appropriately. However, if the dimensions are too large, the feeling becomes stiff and unsuitable for cushioning materials such as mattresses. The main body 1 can be a regular triangular tube, a regular square tube, a regular pentagonal tube, a regular heptagon tube, or the like. However, in a regular triangular tube or a regular square tube, the number of the arm plates 2 and the outer plates 3 is reduced. When stuffed into the skin, such as a mattress, the entanglement of each other becomes weaker and easier. Also, in the case of a regular hexagonal cylinder or a regular octagonal cylinder, the interval between the adjacent outer plates 3 is too narrow, so that the entanglement is weakened, and it becomes easier for the user. The main body 1 can be a simple polygonal cylinder instead of a regular polygonal cylinder, but it costs much to manufacture a mold for an extruder.

[0010] As shown in Fig. 3, such a cushion C is uniformly packed in a breathable skin 11 of, for example, a metal width, and is subjected to a killing process so as not to be stiff. Of course, it can be used for pillows and other rugs as well.

A mattress or the like using the cushioning material C is easily deformed by elasticity even if a body pressure is applied, so that there is no pain. It is good to lay on top.

[0012]

[Effect of the invention]

 The body pressure is supported by a large number of cushioning materials with appropriate elasticity, and even if the body pressure is applied, it does not completely collapse and the space remains, so that air permeability can be secured without obstructing blood circulation. Further, since the arm plate and the outer plate are entangled with each other, the arm plate and the outer plate do not clinch in the epidermis.

[0013] The cushion material is extremely light, so that it is easy to handle. In addition, since plastic is used as a raw material, the mattress and the like can be washed as a whole to be sanitary.

[0014] If a powder having a large number of fine pores such as charcoal and activated carbon as a main component is mixed with a thermoplastic resin to form a mixture, it absorbs moisture, harmful gases, harmful substances, and the like. It does not make you sleepy and does not emit odor.

It is inexpensive because it can be manufactured at low cost by extrusion.
