Description

  The present invention is a low-intensity device that can reliably hold an infant's body when bathing together when the infant bathes, even when the infant's body is washed and when a person bathing together is washing the body. It is an object of the present invention to provide an infant cushion mat that uses an impact-resilience foam and can safely lie down or sit down.

Currently, if an infant is placed in a place where the eyes can reach in the bathroom temporarily when the infant takes a bath, generally, if the infant has a neck, the bus can be sat there There is a chair (see Patent Document 1), but there is a case where it is laid directly on a washing mat (see Patent Document 2) made of foamed polyurethane etc. used as a slipper for bathroom floors, and as a utility model An infant bathing mat (see Patent Document 3) that can be used for bathing while the infant is laid has also been announced. There is also information that general sponge cushions are used. If they are not used, the person bathing with the infant must continue to hold the infant.

  As described above, the conventionally known baby chair represented by Patent Document 1 is difficult to use unless it is an infant with a sitting neck, and must be lifted and washed when washing the body. In the washing place mat of Patent Document 2, it is difficult to maintain the posture of the infant, and when the mother with weak strength holds the infant by the thinness of the washing place mat itself, the infant should be washed with soap when holding the infant. There is a risk that Furthermore, in the sponge sheet, if it is hard, it is not enough to support the infant's body gently, and because of the characteristics of the sponge itself, it is easy to absorb water and difficult to dry, so it will become moldy and germ free and unsanitary. Yes, these are troublesome in the storage place when not in use, but if you do not use these instruments, it is difficult for your mother to wash her body and you have to make time to wash your body separately A scene comes out. For these reasons, there is a demand for safe bathing with infants.

As an example other than the above, for example, a bath mat for infants described in Patent Document 3 has been proposed. This bath mat is a “material that can support the weight of an infant laid down using a polyurethane foam filter material as a base material”. However, it does not specify what kind of polyurethane foam it is, and it is only written as a general generic name. Furthermore, this document 3 states that “if the floor is 15-30 mm or less, it is easy to wind the entire bath mat in a roll and bind it with a string or the like” or “in order to prevent it from rolling horizontally, The material can be assumed to be a hard material as in the case of the washing mat made of foamed polyurethane and the above sponge sheet, so in this structure the polyurethane foam itself It does not hold the entire body firmly. In order to make up for this drawback, the document 3 has a structure of “adhesing a soft foamed resin sheet such as urethane in order to relieve irritation on the skin of an infant and increase frictional force to make it difficult to slip”.

  In order to solve the above-mentioned problems, the present invention has a low resilience elastic foam that is shaped to match the shape (unevenness) of the infant's body that can hold the infant's body firmly and can hold the body in a natural position. A waterproof sheet made of a polymer material with excellent water resistance, such as cushion rubber, and a cushion material of 3 cm to 30 cm, preferably 5 cm to 15 cm from the viewpoint of ease of use so that the body can be sufficiently retained (for example, Tempur material) A low-resilience cushion mat for infants is provided which is sealed with a thin film and has a structure that does not impair the characteristics of the low-resilience material, and is provided with a reclining mechanism, a foot stopper mechanism, and a function of moving the pillow part.

This cushion mat has a thickness of at least 3 cm that can hold the body from a thickness made of a low-resilience elastic foam to about 30 cm from the surface of usability, preferably 5 cm to 15 cm. The cushion mat itself changes its shape along with the shape of the body (irregularities), so the neck and body can be maintained in a natural position.

In particular, for infants before the neck is placed, the low-resilience material firmly holds the infant's body in the state of being laid on the cushion mat as described above, and a water-resistant polymer material such as cushion rubber. It is sealed with a thin sheet of tarpaulin made of, and the structure of the low resilience material is not impaired, so the infant's body can be washed, hot water can be poured, the cushion mat can sink due to the infant's weight, and hot water can be stored easily It also takes the form of a baby bath, and when the mother is washing her body, the infant can lie down and rest assured that it is easier to manage her physical condition.

In addition, by sealing with a waterproof sheet made of a polymer material with excellent water resistance, such as the cushion rubber described above, the structure does not impair the characteristics of the low resilience material, so that moisture directly enters the cushion sheet. Without generation, mold and bacteria can be prevented. In addition, by increasing the thickness of the cushion mat made of low-elasticity material, even if the hand slips with soap and drops the infant, the shock absorption is high, so the risk of injury can be reduced. You can take a bath in mind.

By incorporating a movable part that can be moved in several steps, which has been used in conventional chairs and cushion mats, to prevent slipping on the cushion mat, the body can slip down when used while sitting. Suppress and become more secure, safe and convenient.

If necessary, the head of the cushion mat can be moved in several steps within the range of about 5 degrees in the back and about 20 degrees in the foreground. It is easier to use when lifting the head a little and stabilizing the head, or when washing the neck that is difficult to wash by raising the chin, and when the cushion mat is reclined. It becomes convenient.

The above-mentioned cushion mat can be easily washed with water and easily wiped off moisture by using a structure in which a thin film of a waterproof sheet made of a polymer material with excellent water resistance such as cushion rubber is sealed. It is more hygienic by allowing antibacterial coating, and it can be used as it is in the dry state as well as when taking a bath, or it can be used instead of a mattress in a room or in a crib. it can.

According to the present invention, the “thin film of a waterproof sheet made of a polymer material having excellent water resistance such as cushion rubber” has a rubber-like elasticity as a physical property equivalent to polyvinyl chloride and elastomer resin, and is excellent. A thin film made of water, acid, alkali, flame retardant, and electrical insulation.

For reference, polyurethane foams include rigid polyurethane foam and flexible polyurethane foam, as listed at the top of the Japan Urethane Association Q & A window. One type of flexible polyurethane foam is low-resilience foam, and the density of the low-resilience foam is shown in the second question A in the fourth question, What is low-resilience foam? Is 80 kg / m3 to 40 kg / m3 and the impact resilience is 2% to 4%, whereas the density of general flexible polyurethane foam is 40 kg / m3 to 20 kg / m3, and the resilience is 50% to 40%. The most recommended tempur among the low resilience foams proposed by the inventor is as described in 1 of the characteristics of tempur listed at the top of the tempur website, body pressure dispersion. It is a special viscoelastic polyurethane foam with an open cell structure that sensitively senses the body temperature and weight of the person and supports the body while sinking slowly. This open cell structure changes the shape of the tempur itself according to the shape of the body. The body pressure is dispersed throughout and the pressure on only part of the body is greatly halved. In addition, it reacts to the shape of the body as it is, so the neck and body can be captured in an accurate position, and an ideal S-shape can be maintained. As soon as there is no body pressure, it will return to its original shape. This is the decisive difference from ordinary urethane foam. It is written. This is exactly what the inventor is particular about low resilience foam. Recently, a new type of low-resilience foam has been announced due to various requests.

Furthermore, as described in Tempur's 2nd page, Tempur's characteristics on the Tempur website, “Tempur is produced by reacting with water in a solvent. In other words, it is harmless to the environment. . 3. Sanitary written, “Tempur material is antibacterial and will not produce bacteria.”
Note that this feature is very effective in the present invention for infants.

FIG. 2 is a sectional view of the cushion mat of the present invention. 3A, 3B, and 3C are perspective views in which a movable portion is provided on the cushion mat of the present invention, and FIG. 3D is a side view of a gear of the movable portion. FIG. 4 shows an embodiment in which the cushion mat of the present invention is folded in three.

Specific embodiments and shapes of the present invention will be described with reference to the drawings. 1 to 2 show the first embodiment.

As shown in FIG. 2, the cushion sheet is made of a low resilience elastic foam 1, such as Tempur material, so that the infant's body can be firmly held, and the periphery thereof is made of a polymer material having a large elasticity at room temperature. A cushion mat that is completely tightly sealed with a thin film 2 such as a thin film made of polyvinyl chloride or an elastomer resin is prepared. For example, an infant whose average height is about 75 cm and the width is about 45 cm. The body should be sized so that it can be wrapped, and the thickness of the body should be 3 cm to 30 cm, preferably 5 cm to 15 cm to support the weight of the infant and about 5 cm to about 20 cm from the end of one side of the width. A shape having a pillow portion 4 that is gradually increased in thickness by about 3 cm. The length and width dimensions may be appropriately adjusted as desired.

As described above, the cushion sheet is made of low resilience foam 1 such as Tempur material, and its thickness is at least 3 cm to 30 cm, preferably 5 cm to 15 cm, so that the shape of the infant's body in the laid state (unevenness) ), The cushion mat itself is deformed, so the neck and body can be maintained in a natural position and the body can be held firmly. If desired, the cushion mat made of a low resilience material may be made thicker to make it feel more wrapped.

The above cushion sheet is a waterproof sheet thin film made of a polymer material with excellent water resistance such as cushion rubber, for example, a thin film 2 made of polyvinyl chloride. Can be done. As a result, generation of mold and bacteria on the cushion sheet itself can be prevented, and the cushion sheet can be kept clean. Because of the above characteristics, it can be used safely in the room.

As shown in FIG. 3 (a), the movable part 3 using the movable gear shown in FIG. 3 (d) used in the curved part of a general sofa bed or a chair is built in the central part of the cushion mat. By using it, it is easy to carry it in half, and at the same time, by having a reclining mushroom mechanism, it is also possible to sit an infant who can sit on it.

Also, as shown in FIG. 3 (b), the cushion mat can be used by incorporating the movable part 3 described above as a foot stopper part 5 at about 10 cm from the foot side of the cushion mat. It is possible to maintain the posture of the infant so that the infant does not slide down when the reclining is used.

Also, as shown in FIG. 3 (c), the pillow part of the cushion mat is movable in several steps within a range of about 5 degrees at the back and about 20 degrees at the front of the movable part 3 described above. The built-in movable function already used in seats and chairs makes it easier to hold the head when reclining the cushion mat. On the other hand, it is convenient when you raise your chin and wash your neck.

In addition, as shown in FIG. 4, the cushion mat can be folded in three so that it can be made more compact when transported, and storage space can be reduced. It is easy to use and can be easily used at travel destinations.
