Description

Mattresses with different hardness and elasticity corresponding to body parts

The present invention relates to a mattress having different hardness and elasticity corresponding to a body part, and more particularly, to form an unit member having different hardness and elasticity corresponding to a body part to achieve an optimum body pressure dispersion and body shape maintaining effect. The present invention relates to a mattress having different hardness and elasticity in response to a body part that can help to lower EMG and improve blood flow, and help maintain a good sleep, secure muscle flexibility, and maintain an ideal shape of a skeleton.

The lifestyle of modern people is due to the rapid change. Cervical spine and spinal diseases are rapidly increasing regardless of age, sex and age due to change of transportation, self-driving, using computer and mobile phone, watching TV, competitive study, and simple repetitive work. Because there is.

Therefore, to prevent this, we recommend pre-exercise pre-exercise, steady posture and steady exercise to help lower back muscles, rest and stretching.

A good posture of 20 minutes or more can strain your spine and surrounding tissues. Stretching for about 10 minutes every 50 minutes or doing stretching exercises such as neck and back exercises can help you maintain the correct posture.

Another alternative is the choice of bedding to help maintain a good posture during sleep.

Sleep is the act of maintaining the same posture for the longest time, and the development of a mattress that can release the rigid back muscles and ligaments during the day, relax the compressed bones and properly shape the skeleton is the most important task. Can be.

Therefore, in consideration of the body characteristics of each part of the human body, the development of mattresses with different hardness and elasticity for each area of the mattress has been actively progressed.

As described above, if the hardness and elasticity of each area of the mattress are set differently in response to the body shape of each part of the human body, the optimal EMG value can be maintained by ideally supporting the lumbar and thoracic flexion, and the elasticity is supported by compressing the buttocks. By inducing body pressure distribution and body shape maintenance at the heel off, thigh and calf areas, it is possible to naturally relieve and correct musculoskeletal disorders caused by bad posture as well as correct sleep during sleep. It is possible to restore muscle flexibility by releasing stiff muscles and ligaments during the day by releasing body pressure and maintaining EMG values.

As the prior art of the mattress with different hardness and elasticity set for each region in order to realize the above effects, as shown in FIG. 1, a mattress made of a single material of polyurethane foam or latex foam having the same hardness and elasticity. By forming a plurality of grooves 11 having different diameters on the surface of (10), a mattress having different hardness and elasticity for each area according to the diameter of the grooves 11 has been proposed.

However, the prior art as described above, even if the grooves are formed, the hardness and elasticity of the material itself is the same, the difference in hardness and elasticity of each region is extremely insignificant, and when used for a long time, wrinkles between the arranged grooves 11 There was a problem that the groove 11 is pressed and not properly implemented its function.

On the other hand, as another conventional technology of the mattress set different hardness and elasticity for each area, Patent Document 1, as shown in Figure 2, in the mattress for supporting the body of the person, the expected working load by the body A plurality of structures of independent elastic bodies 11 arranged to have different hardnesses according to areas of the mattress by distribution; A support body 12 of an independent elastomeric structure for holding the structures of the independent elastomers in a predetermined position by having a plurality of holes into which the structures of the independent elastomers are respectively inserted and coupled; And a shell 15 for receiving the structures 11 of the independent elastic bodies and the support 12 of the structures of the independent elastic bodies, wherein the structures 11 of the independent elastic bodies are made of foams having different hardnesses and have a body. It is proposed to have a concave portion 11a so as to be elastically movable in the vertical direction in accordance with the load.

However, in the prior art as described above, a space is generated between the structures 11, and a separate structure is not filled in the space, and thus the urethane sponge 13 formed on the top of the structures 11 due to a hand or a foot. There was a problem that occurs when the torn.

Therefore, the present invention has been proposed to improve such a conventional problem, by forming a unit member having a different hardness and elasticity corresponding to the body parts to implement the body pressure dispersion and body shape maintenance effect to lower the EMG and improve blood flow In addition, the object of the present invention is to provide a mattress having different hardness and elasticity in response to a new type of body part which can help to maintain a good sleep, secure muscle flexibility, and maintain an ideal shape of a skeleton.

In particular, head and neck, shoulder, waist, hip, thigh, and calf have the hardness and elasticity according to the musculoskeletal structure and physiological characteristics of six body parts. It is an object of the present invention to provide a mattress having different hardness and elasticity in response to a new form of body parts to be implemented.
