The present invention relates to a functional bed structure.

More specifically, a functional bed that allows the spacing of pillows to be adjusted according to the body of the user using the bed, and also allows individual height adjustment tailored to the user based on the structure of the face, shoulders, arms, and the rest of the body. It's about rescue.

In addition, in the case of a user sleeping sideways, the pressure on the arms and shoulders can be minimized, which can benefit the body such as bones and muscles, as well as minimize the pressure, which is beneficial for blood circulation. .

A bed has been used as a useful tool for people to sleep for a long time.

Ordinary beds are released according to a set standard, and unless the user's physical condition or sleeping style is outside the normal range, there is no great inconvenience in using the bed according to the standard.

However, as consumers' interest in health increases in recent years, the link between sleep and health, such as bedtime and sleeping position, is attracting attention.

In fact, when using a bed, it does not matter much for people who sleep upright, but in the case of sleeping on the side, as a part of the body is excessively pressed, the posture is broken and not only burdens the bones accordingly, but also damages the blood due to continuous pressure. Even problems with circulatory disorders have been discovered.

Accordingly, the present applicant came to conceive of a technique capable of overcoming the above-mentioned problems.

As a related technology, Patent Registration No. 10-0752939 discloses a functional bed.

The technology is a means for making the bottom surface form a smooth curve considering the human body structure, and the bottom of the upper body, the bottom of the thigh, and the bottom of the calf are formed at a certain angle and inclination, and the part supporting the knee, hip, and neck is a soft curve. It relates to a functional bed configured to be able to adjust the length of the bottom of the upper body and the bottom of the thigh according to the human body shape, and to adjust the height and inclination of the pillow.

This functional bed allows the user to maintain a comfortable leg posture, and the back, waist, and neck are formed to fit the human body shape, allowing for comfortable sleep. In addition, it allows the elderly and infirm who have a particularly uncomfortable back to take a sufficient rest and relieve the fatigue of the legs, which are the most fatigued during the day. In addition, the curvature of the bottom surface of the bed can be adjusted to suit the body shape of a sound sleeper to increase the above effects, and the neck and back of the head can be fully tilted as much as the user wants, so it can be tailored to the user's preference.

At this time, the pillow 30 may be configured separately according to the number of occupants of the bed for one bed, as shown in FIG. 2 of the accompanying drawings. For example, when the bed is for two people, the structure of the pillow 30 may be composed of two as shown in FIG. 2 of the accompanying drawings.

At this time, it is preferable that all of the pillows 30 having a plurality of numbers are provided on the upper side of one plate portion 20, but for the purpose of individual height adjustment, the plate portion 20 also corresponds to the number of pillows 30 It can also be configured to have a corresponding number.

In addition, the plate portion 20 may be configured such that a guide pin 23 penetrates in order to assist height adjustment by the height adjusting bolt 21 . To this end, a hole through which the guide pin 23 passes may be formed in the height direction of the plate portion 20 .

In addition, the other side of the guide pin 23 can be penetrated through the bed frame 10. To this end, the bed frame 10 is formed in the height direction at a position corresponding to the hole of the plate portion 20. It may contain 2 more holes.

At this time, the guide pin 23 includes a head by being formed by extending the end in the direction of the bed frame 10 into two stages, and the head can be coupled to the bed frame 10 using bolts or the like. .

However, this is only an example, and the guide pin 23 may have other configurations that are obvious at the time of filing of the present invention that can be coupled to the bed frame 10.

In addition, a plurality of configurations such as the guide pin 23, the hole, and the second hole may be included, and through this, it is possible to guide the height adjustment of the plate part 20.

In addition, the length of the guide pin 23 may preferably have a height at which the guide pin 23 does not exceed the plate portion 20 when the plate portion 20 is located at the lowest height.

Depending on design conditions, the diameters of the hole and the second hole are formed to be larger than the diameter of the guide pin 23, but a concave groove is formed on one side of the outer surface of the guide pin 23, and a shaft is formed inside the groove. Can be configured to include combined wheels (or rollers). At this time, the shaft fixing the wheel is inserted into an additional groove formed on both inner walls of the groove portion facing each other. At this time, a spring is provided in the additional groove to elastically support the axis of the wheel.

Therefore, the wheel (or roller) has elasticity that can be pressed inward from the inside of the groove. In addition, a contact sensor may be included on an inner surface of the groove in a direction in which the wheel is pressed.

In addition, the inner surface of the second hole of the bed frame 10 through which the guide pin 23 passes may include a plurality of protrusions formed along the height direction at regular intervals.

That is, it is detected by the sensor that the wheel of the guide pin 23 is caught and pressed on the protrusion. At this time, one side of the bed frame 10 receives a signal from the sensor and determines based on the configuration and a control panel including a display unit configured to perform a display according to a result determined by the determination unit.

Therefore, when signals are not received from all of the sensors provided in each of the plurality of second holes, the determination unit determines that all are not received and displays using LEDs through the display unit. Accordingly, the plate unit ( 20) may not rise uniformly, so that the user can understand.

The above-described pillow may be used, for example, a pillow for which the present applicant has applied for and secured the right. The pillow uses those described in Patent Registration No. 10-1993735, a functional pillow in which negative ions are emitted, and a manufacturing method thereof.

In other words, the pillow is a functional pillow that emits negative ions, and emits a large amount of far-infrared rays and negative ions, and relates to a functional pillow that exhibits excellent antibacterial and deodorizing effects as well as humidity control and a manufacturing method thereof.

functional pillow

The above-described functional pillow that emits anions is composed of polypropylene glycol (PPG), methylene diphenyl diisocyanate (MDI), ocher pozzolan and rare earth elements, 100 parts by weight of polypropylene glycol, methylenedi It is preferably composed of 35 to 45 parts by weight of phenyl diisocyanate, 50 to 60 parts by weight of ocher pozzolan, and 20 to 30 parts by weight of rare earth.

The polypropylene glycol reacts with the methylenediphenyl diisocyanate to form polyurethane, which is the main material of the functional pillow in which anions are released according to the present invention.

In general, the main reaction of polyurethane is the reaction between the hydroxyl group and isocyanate group of polyol, but since the reactivity of isocyanate is very strong, the following various side reactions are simultaneously accompanied. In particular, the reaction with water during the side reaction generates carbon gas and is used in the manufacture of foam, and the formation of trimer of diisocyanate increases heat resistance as an additional cross-linking structure, which is the main focus of polyisocyanurate foam. being used as a reaction.

The methylenediphenyldiisocyanate is contained in an amount of 35 to 45 parts by weight, reacts with the hydroxyl group of the polypropylene glycol to produce polyurethane, and the methylenediphenyldiisocyanate used in the present invention is made of polyurethane Since it reacts violently with moisture in the air during the process, it exhibits excellent reactivity in that most of the residual isocyanate is substituted with a urethane group in the product.

If the content of methylenediphenyl diisocyanate is less than 35 parts by weight, the polyurethane production reaction does not proceed properly because the content is too low compared to the polypropylene glycol, and if the content of methylenediphenyl diisocyanate exceeds 45 parts by weight, toxicity Methylenediphenyl diisocyanate having a is not preferable because side reactants remain.

The ocher pozzolan is contained in 50 to 60 parts by weight, and serves to provide a functional pillow exhibiting far-infrared ray emission, anion emission, antibacterial effect and humidity control effect.

Ocher pozzolan is used in the form of powder having a particle size of 80 to 200 mesh by collecting and pulverizing natural ocher pozzolan mineral widely produced on the west coast of the Korean Peninsula. Silicon Oxide 61~64%, Aluminum Oxide 12~18%, Titanium Oxide 0.5~0.7%, Potassium 3.2~3.8%, Sodium Oxide 1~3%, Iron Oxide 4~5.5%, Manganese Oxide 0.01~0.07%, Magnesium Oxide 1.3 It consists of ~2%, phosphorus oxide 0.04~0.3%, germanium 0.000002%, etc.

Ocher pozzolan powder emits a large amount of 94-97% of far-infrared wavelengths beneficial to human health.

In addition, the ocher pozzolan powder emits an average of 972/cc of negative ions, which emits a very large amount of negative ions among natural minerals, providing a pillow that exhibits effects such as decomposition of harmful substances, supply of oxygen, sterilization, and deodorization. role in making it possible.

In addition, the ocher pozzolan powder is porous and has numerous pores, has a 99.9% sterilization effect of bacteria and bacteria in the air while in contact with air, and exhibits effects such as deodorizing effect, killing mold, avoiding mites, and avoiding aphids.

In addition, the loess pozzolan powder has a dry-wet effect of maintaining optimal humidity by absorbing or discharging moisture according to the humidity in the air. More excellent drying effect is excellent.

If the content of the ocher pozzolan powder is less than 50 parts by weight, the above effect is insignificant, and if the content of the ocher pozzolan powder exceeds 60 parts by weight, the effect of the polyurethane reaction is reduced without greatly improving the effect, A phenomenon in which the ocher pozzolan component does not firmly exist in the polyurethane reactant and is desorbed may occur.

The rare earth powder is contained in an amount of 20 to 30 parts by weight, and serves to provide a functional pillow with a further improved emission of negative ions.

Rare earth metals are a generic term for 17 elements that are a combination of scandium, yttrium, which are group 3A of the periodic table, and 15 elements of the lanthanide series with atomic numbers from 57 to 71. Of the lanthanide elements, 14 elements below cerium, excluding lanthanum, are collectively referred to as lanthanides. In addition, 6 elements from lanthanum to samarium are called cerium group elements, elements from europium to lutetium, yttrium, and 11 elements including scandium are called yttrium group elements. All of these elements belong to rare elements, and promethium is a radioactive element, so stable isotopes do not exist. Odd-numbered atoms are less abundant than even-numbered ones, and are generally silvery-white or gray metals. In addition, it is slowly oxidized in air, soluble in acid and hot water, but insoluble in alkali, and has very similar chemical properties. Usually, all +3 valent compounds are made. There is also +2. Following alkali metals and alkaline earth metals, it is predominantly positive, and hydroxide is a base.

At this time, the rare earth powder is preferably made of lanthanum or cesium having excellent anion emission performance. If the content of the rare earth powder is less than 20 parts by weight, the above effect is insignificant, and if the content of the rare earth powder exceeds 30 parts by weight, the above The effect is not greatly improved, but the manufacturing cost is increased.

In addition, the method for producing a functional pillow in which anions are released is a raw material mixing step (S101) of mixing polypropylene glycol, methylenediphenyl diisocyanate, ocher pozzolan and rare earth powder, and a mixture mixed through the raw material mixing step (S101) A foaming agent inputting step (S103) of injecting and foaming a foaming agent, a foaming heating step (S105) of injecting the mixture in which foaming has started through the foaming agent inputting step (S103) into a mold and heating it (S105), and foaming through the foaming heating step (S105). It consists of a cooling and drying step (S107) of cooling and drying the foamed body.

The raw material mixing step (S101) is a step of mixing polypropylene glycol, methylenediphenyl diisocyanate, ocher pozzolan and rare earth powder, 100 parts by weight of polypropylene glycol, 35 to 45 parts by weight of methylene diphenyl diisocyanate, 50 ocher pozzolan To 60 parts by weight and 20 to 30 parts by weight of the rare earth powder are introduced into a high-speed blender and mixed at a speed of 2500 to 3500 rpm to prepare a mixture.

At this time, since the specific components and roles of the polypropylene glycol, methylenediphenyl diisocyanate, loess pozzolan, and rare earth powder are the same as those described in the functional pillow from which the anion is released, a description thereof will be omitted.

The foaming agent input step (S103) is a step of injecting a foaming agent into the mixture mixed through the raw material mixing step (S101) to foam it. This step is to start foaming of the mixture by mixing parts by weight.

At this time, it is preferable that water or cyclohexane, which is a volatile organic solvent, is used as the blowing agent, but the blowing agent component is volatilized during heating and drying the mixture and is not contained in the final product.

The foaming and heating step (S105) is a step of injecting the mixture in which foaming has started through the foaming agent inputting step (S103) into a mold and heating it. This is a step of forming a functional pillow by foam molding at a temperature of 40 to 50 ° C. for 25 to 35 minutes.

When the temperature of the foaming mold is less than 40 ° C., the foaming of the mixture does not proceed properly, and when the temperature of the foaming mold exceeds 50 ° C., the foaming efficiency is not greatly improved and the physical properties of the polyurethane resin may deteriorate.

The cooling and drying step (S107) is a step of cooling and drying the foamed body through the foaming and heating step (S105). As a drying step, after passing through the cooling and drying step (S107), the foam formed through the foaming and heating step (S105) is gradually cooled to exhibit excellent shape stability, and in this process, foaming agent components such as water are removed. .

What has been described above is only the main points of the present invention, and as much as various designs are possible within the technical scope, the present invention is interpreted in combination with the obvious technical level of those skilled in the art rather than being limited to the main points described above. and may be limited.
