Abstract

The invention discloses a pillow realizing automatic height adjustment, belonging to the field of articles for daily life, aiming at realizing the automatic adjustment on the height of the pillow during the conversion of the two sleep postures, namely, lying on the side and lying on the back, so that the neck is in the comfortable relax state (at the time, the height of the pillow is defined as the suitable height). The pillow comprises an arch-shaped body and a pillowcase; the arch-shaped body is composed of an elastic structure formed by an arch-shaped board and a U-shaped bracket, and a supine height limiting block. By selecting the suitable structural parameters of the arch-shaped body, the two suitable heights of lying on the side and lying on the back are set. During the lying on the side, the head is positioned in the suitable height of the lying on the side. When the lying on the side is converted into the lying on the back, the pressure relative to the pillow of the head (called the horizontal force P for short) increases, the deformation of the arch-shaped board increases, the arch-shaped board loses balance, and the height of the pillow decreases till the suitable supine height is reached; vice versa, when the lying on the back is converted into the lying on the side, the horizontal force P decreases, the arch-shaped board in the unstable state rebounds, then the height of the pillow increases, and the suitable height for lying on the side is achieved.

Description

Medicated pillow

Technical field

Patent of the present invention discloses the medicated pillow of a kind of automatic controlled height; belong to daily necessities field; it is specifically related to human cervical spine portion health science and thin-wall construction Elasticity; it is automatically adjusted pillow height for realizing lying on one's side and lying on the back when two kinds of sleeping postures convert; cervical region is made to be in comfortable relaxation state (pillow height now is defined as proper height), it is thus achieved that the effect of protection cervical region.

Background technology

The multiple medicated pillow that has sold disclosed at present in Chinese patent literature and on market can realize the regulation of little extent height when lying on one's side and lie on the back conversion.Such as, the elastic reasonable medicated pillow of pillow inner filler, low resilience medicated pillow or air-bag pillow are first-class.Sleeping posture is when proper height of lying on one's side is transformed to lie on the back, because medicated pillow is higher than lying on the back proper height, cause rear cervical region muscular tone, head increases for the pressure (hereinafter referred to as cross force P) of medicated pillow, pillow inner filler compression increases, pillow height diminishes, until the medicated pillow support reaction balance that cross force P that change is big is big with change, it is achieved the little range regulation of pillow height under the conditions of non-proper height.Otherwise, sleeping posture is when proper height of lying on the back is transformed to lie on one's side, because pillow height is less than lying on one's side proper height, cause muscular tone on the upside of cervical region, making cross force P reduce, pillow inner filler compression reduces, and pillow height becomes big, until cross force P diminished and the medicated pillow support reaction balance diminished, it is achieved the medicated pillow little extent height regulation under the conditions of non-proper height.But when head is in non-proper height on medicated pillow for a long time, a part of muscle of cervical region is the most in tension, stiff neck symptom easily occurs.Also have U-shaped combination medicated pillow (middle relatively low, both sides are higher) to be capable of the proper height lain on one's side and lie on the back, but cannot realize being automatically adjusted, i.e. need to be put into by head consciously prone position corresponding proper height during conversion sleeping position.Also have the scheme utilizing dynamo-electric automatic control technology to realize two kinds of sleep proper heights, but structure is complicated, relatively costly.

Summary of the invention

How pillow height is automatically adjusted when patent of the present invention provides the conversion of a kind of people's sleeping posture the solution to proper height.When people sleep, if head deviation proper height, a part of musculi colli can be made to go short of, cause cross force P value when proper height of lying on one's side is transformed to lie on the back to become big, when proper height of lying on the back is transformed to lie on one's side, cross force P value diminishes.The conversion of patent utilization of the present invention prone position changes the rule worked for cross force P value, and being designed to can be at the arch thin walled elastic structure (abbreviation toxoplasma) of two proper heights all energy autobalance cross forces P of lying on one's side and lie on the back.Put the soft pillowcase reducing head protruding parts contact stress outside toxoplasma, be just made for being automatically adjusted the medicated pillow of proper height.Wherein toxoplasma is made up of cambered plate, U-bracket and limited block.There is elastic deformation in cambered plate under the effect of cross force P, U-bracket provides elastic restraint for cambered plate, and limited block limits cambered plate buckling deformation.By selecting suitable structural parameters, medicated pillow elemental height is higher than lying on one's side proper height, but when lying on one's side, the lower cambered plate of cross force P effect is deformed into proper height of lying on one's side, and reaches poised state.Lie on one's side when being transformed to lie on the back, because medicated pillow is higher than lying on the back proper height, cross force P increases, and cambered plate deformation increases, pillow height diminish to close to lie on the back proper height time, power (being called for short longitudinal force N) parallel with cambered plate face in cambered plate reaches the marginal value (abbreviation Ncr) of unstability,Cambered plate unstability, and cross force P is less than or equal to continuing deformation under the conditions of Pcr, and pillow height continues the proper height of lying on the back being decreased to be determined by limited block height, reaches poised state.Otherwise, proper height of lying on the back when being transformed to lie on one's side, because pillow height is less than lying on one's side proper height, cross force P is significantly less than Pcr, longitudinal force N is less than Ncr, the cambered plate bounce-back of instability status, and deformation reduces, pillow height increases, and returns to proper height of lying on one's side, reaches poised state.Patent of the present invention provides the benefit that: no matter how the sleeping posture of people converts, and all can automatically make head be in corresponding proper height, effectively protect ceruical uertebra part.
