Description

  The present invention relates to a recumbent posture mattress that is used as a mattress, and makes it easy to maintain a recumbent posture by suppressing the compression of the shoulder upper arm and the buttocks in the recumbent posture.

  Conventionally, in order to live a healthy life, sleep is one of the important elements, and various materials and shapes have been researched and developed for mattresses and mattresses used at bedtime.

  In recent years, sleeping in a recumbent posture has been effective in preventing apnea syndrome and suppressing snoring, so that even when lying in a recumbent posture during sleep, do not feel a sense of pressure on the shoulder or upper arm A mattress that can be used is disclosed in Patent Document 1.

In this mattress, as shown in FIG. 4, a groove portion 3 is formed between the pillow lower portion 1 and the body portion 2, and a protruding portion 4 protruding into the groove portion 3 is provided in the vicinity of the upper center portion of the body portion 2. It is.
Japanese Utility Model Publication No. 1-61163

  A mattress with such a groove can improve the feeling of pressure on the shoulder and upper arm when lying down, but this groove alone does not necessarily fit the user's body shape and is lying down There are problems that other parts of the human body become cramped and a feeling of pressure appears.

  In addition, in the mattress as shown in FIG. 4 in which grooves are formed in the portions corresponding to the shoulder and upper arm, the most stable posture is sleeping in the supine posture, and the posture is actively shifted to the lying posture and maintained. Not to be.

  The present invention has been made in view of the above-mentioned problems of the prior art, and provides a mattress for lying posture that is easy to shift to a lying posture and can maintain a lying posture without feeling pressure or cramping. It is something to try.

  Therefore, as a result of earnest examination about the human body lying posture at bedtime, it is not enough to form a recess such as a groove to avoid pressure on the portion protruding downward in the shoulder posture such as shoulder or hip The present invention has been completed by finding that it is necessary to support without being pressed in accordance with the amount of protrusion, and to support the back of the human body from behind to maintain the lying posture.

  That is, in order to solve the above-mentioned problem, a lying down mattress according to claim 1 of the present invention comprises a core body having a recess and a core for a recess provided in the recess, and the core body is in the width direction. A longitudinal body portion having an appropriate width extending in the longitudinal direction in the middle, and a width-direction body portion having an appropriate width extending in the width direction intersecting the longitudinal body portion at a position corresponding to the human body torso, are formed by recesses. The four concave portions partitioned by these main body portions are two shoulder upper arm concave portions corresponding to the shoulder upper arm portion and two hip concave portions corresponding to the hip portion. The core material for the concave portion is made from the material of the core main body. It is composed of a soft material.

  Here, the appropriate width of the longitudinal body portion is determined according to the chest width of the human body in order to shift the user to a lying posture with the body portion as a support shaft. The average chest width of an adult male is about 280 mm. Therefore, it is set to 20 to 200 mm, and is changed depending on whether the user is small or large.

  Also, the appropriate width of the width direction main body portion is determined to support the human body body from the horizontal direction and the longitudinal direction main body portion to support the human torso from below. If it is too narrow, the human torso cannot be supported from below, so it is 40 to 200 mm, and it is changed depending on whether the user is small or large.

  Furthermore, in addition to the structure of claim 1, the recumbent posture mattress according to claim 2 of the present invention is such that the upper surface of the core material body and the upper surface of the core material for recesses are flat continuous surfaces. It is a feature.

  In addition to the configuration of claim 1 or 2, the mattress for recumbent posture according to claim 3 of the present invention is configured such that each core material is made of a synthetic resin foam, and the hardness of the core material for recesses is 40-90N (JISK6400: D method), and the core material body is harder than the recess core material by 60-120N, while the core material body has a thickness of 60 mm or more. The thickness for the shoulder upper arm is 30 to 50 mm, the thickness for the buttocks is 10 to 30 mm, and the thickness for the buttocks is 15 mm or more thinner than that for the shoulder upper arm.

  Furthermore, in addition to the structure in any one of Claims 1-3, the mattress for recumbent attitude | position of Claim 4 of this invention comprised the said core material for recessed parts with the low-resilience polyurethane foam, It is characterized by the above-mentioned. Is.

  According to the recumbent posture mattress according to claim 1 of the present invention, it is constituted by a core material body having a recess and a core material for the recess provided in the recess, and the core material body appropriately extends in the longitudinal direction in the middle in the width direction. A width-wise main body portion and an appropriate width-direction main body portion extending in the width direction intersecting the longitudinal main body portion at a position corresponding to the human body torso are formed by recesses, and are partitioned by these main body portions 4 The two recesses are two shoulder upper arm recesses corresponding to the shoulder upper arm and two butterfly recesses corresponding to the buttocks, and the recess core material is made of a material softer than the core body material, The user can easily shift to the horizontal posture in the left or right direction with the longitudinal body portion as the support shaft, and in the horizontal posture, the shoulder portion on either the left or right side is provided with the concave core provided in the concave portion for the shoulder upper arm portion. And lower the upper arm while lowering the shoulder and upper Can support the back of the human body from the back (horizontal direction) with the main body in the longitudinal direction, and can support the human torso from below with the main body in the width direction. The recumbent posture can be continuously maintained without feeling a sense of pressure.

  Furthermore, according to the mattress for recumbent posture according to claim 2 of the present invention, the upper surface of the core material body and the upper surface of the core material for the recesses are flat continuous surfaces. In addition, the durability of the mattress itself against repeated loads is improved because the upper surface is continuously flat.

  Moreover, according to the mattress for recumbent posture of Claim 3 of this invention, each said core material is comprised with a synthetic resin foam, and the hardness of the core material for recessed parts shall be 40-90N (JISK6400: D method). The core body has a hardness 60 to 120 N higher than that of the recess core, while the core body has a thickness of 60 mm or more, and the shoulder upper arm has a thickness of 30 to 30 mm. Since the thickness for the buttocks is 10 to 30 mm and the thickness for the buttocks is 15 mm or more thinner than that for the shoulder upper arm, the hardness and thickness are set within these ranges in consideration of the load and protrusion amount by the human body. The user can maintain the recumbent posture continuously and with excellent comfort.

  Furthermore, according to the mattress for recumbent posture according to claim 4 of the present invention, the core material for the recess for the shoulder upper arm portion is made of low-resilience polyurethane foam. The pressure becomes even smaller.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.
1 to 3 relate to one embodiment of a mattress for lying posture according to the present invention, FIG. 1 is a schematic perspective view, FIG. 2 is a plan view and a side view corresponding to a human body, and FIG. It is explanatory drawing of the use condition in.

  This recumbent posture mattress 10 includes a synthetic resin foam core material body 11 and recess core materials 21, 22, and 23, and has the same size as a normal mattress, for example, a length of about 2000 mm, The upper core 12, the middle core 13, and the lower core are divided into three equal parts by two folding portions 11 a so that the width is about 1000 mm and the thickness is 60 mm to 100 mm and can be folded into three. It is composed of the material 14.

  In the core body 11, a longitudinal body 15 having an appropriate width extending in the longitudinal direction is provided in the middle of the upper core 12 from the middle in the longitudinal direction to the lower end and the middle core 13. A width-direction main body portion 16 having an appropriate width extending in the width direction is provided in a region on the upper end side of the core member 13, and the main body portion 15 is divided into four regions that are partitioned in a cross shape by the longitudinal-direction main body portion 15 and the width-direction main body portion 16. , 16 are provided with four recesses 17, 18 that are recessed.

  Furthermore, the core material body 11 is provided with a lower width direction main body portion 19 straddling the intermediate core material 13 and the lower core material 14, and the main body portion 19 is provided in a region below the lower width direction main body portion 19. On the other hand, a recess 20 is provided in the entire width direction that is recessed.

  Therefore, in this lying position mattress 10, a total of five recesses 17, 18, and 20 are formed on the upper surface of the core material body 11, and other than these recesses are flat surfaces equal to the thickness of the core material body 11. Yes.

  The longitudinal body 15 provided in the core body 11 is a part for supporting the back of the human body in the recumbent posture from the back, and the body 16 in the width direction is the human body torso in the recumbent posture from below. It is a part to support.

  The longitudinal main body 15 has a width of 80 to 200 mm, is provided about 300 mm from the upper end of the upper core 12 of the core main body 11, and is provided about 100 mm from the lower end of the intermediate core 13. The main body portion 16 has a width of 40 to 200 mm and is provided in a region on the upper end side of the intermediate core material 13.

  Further, the lower width direction main body portion 19 provided across the intermediate core material 13 and the lower core material 14 has a width of about 100 mm at the intermediate core material 13 portion and a width of about 200 mm at the lower core material 14 portion. .

  On the other hand, of the recesses 17, 18, and 20 of the core body 11, the recess 17 of the longitudinal body 15 is a shoulder upper arm recess for sinking the human body shoulder and upper arm in a lying position. Reference numeral 18 denotes a buttock recess for sinking a human buttock in a lying position. Moreover, the recessed part 20 of the whole width is made into the recessed part for leg parts for sinking a leg part.

  Further, the shoulder upper arm recess 17, the buttock recess 18 and the leg recess 20 are respectively provided with a recess core 21 made of a synthetic resin foam softer than the synthetic resin foam constituting the core body 11. 22 and 23 are fitted, the hardness of the core material for recesses 21, 22 and 23 is 40 to 90 N (JISK6400: D method), and the hardness of the core material body 11 is 60 to 60 from the hardness of the core material for recesses. 120N is hardened (the hardness of the core body is 100 to 210N).

The concave core materials 21, 22, and 23 are bonded to the concave portions 17, 18, and 20, and the upper surfaces of the concave core materials 21, 22, and 23 are flat and continuous with the upper surface of the core material body 11. It is intended to make.
When the cores 21, 22 and 23 for recesses fitted into the recesses 17, 18 and 20 have a hardness of less than 40N, or 90N or more, body pressure dispersibility can be achieved for a user with a general physique in a lying posture. It may not be demonstrated well.

  Further, if the difference between the hardness of the core material body 11 and the hardness of the core materials 21, 22, 23 for the recesses is less than 60 N, it is difficult to shift to the recumbent posture and it is difficult to maintain the recumbent posture. The difference in hardness is too large at the boundary between the core body 11 and the recess cores 21, 22, and 23, and the body pressure dispersibility deteriorates at this boundary and may cause the user to feel a foreign object. .

  The depth of the shoulder upper arm recess 17 and the thickness of the recess core 21 are set to 30 to 50 mm so that the human shoulder and upper arm in a lying position are submerged. The depth of 18 and the thickness of the core 22 for recesses are 10 to 30 mm so that the human body buttocks in the lying position are submerged, and the depth and thickness for the buttocks are shoulder upper arms. It is 15 mm or more shallower (thin), for example, 15 to 40 mm shallower (thin) than the conventional one. The depth of the leg recess 20 and the thickness of the recess core 23 are about 30 mm. In addition, the thickness of the core material main body 11 shall be 60 mm-100 mm from viewpoints, such as a weight and storage property.

  Further, the recumbent posture mattress 10 is preferably flat on the entire upper surface, but the portion where the core material for the recess is present may be slightly raised or recessed. In this case, it is appropriate that the “swell” and “recess” are within 10 mm.

  If the depth of the shoulder upper arm recess 17 and the thickness of the recess core 21 are less than 30 mm, the compression of the human shoulder and upper arm in the lying posture may not be able to be reduced. There is a tendency that the effect of reducing the size does not increase so much.

  The reason why the depth of the recess 18 for the buttock and the thickness of the core material 22 for the recess are relatively small, 10 to 30 mm, is that the sinking of the shoulder and upper arm is increased, while the sinking of the human buttock is decreased. This is because the body pressure dispersibility with respect to the entire human body in the lying posture is improved.

  A synthetic resin foam of low-resilience polyurethane foam is used as the concave core materials 21, 22, and 23. It has the property of slowly restoring when the load is released. It is flexible at room temperature with a higher glass transition point (normal temperature or near normal temperature) than general polyurethane foam, but it loses its elasticity moderately. By using this form, it is possible to further reduce the feeling of pressure on the human shoulder, upper arm, and buttocks in the lying posture.

  In addition, the mattress 10 for lying posture is covered with a breathable cover when used.

  In the recumbent posture mattress 10 thus configured, a longitudinal body 15 is provided at the center of the core body 11, and a soft recess core 21 is provided on the shoulder upper arm recess 17 and the buttocks recess 18 on both sides thereof. , 22 are fitted, so that both sides are soft with the longitudinal body portion 15 as a boundary, and the user can easily shift to the lying posture on both the left and right sides, and the shoulder portion and upper arm portion of the lying posture are for the shoulder upper arm portion. A feeling of pressure can be reduced by being supported by the recess core material 21 in the state of sinking in the recess 17 and being supported by the recess core material 22 in a state of sinking the collar portion in the recess recess 18.

  Furthermore, the human body torso in the lying position is supported from below by the width direction main body part 16, and the shoulder part to the buttocks of the human body in the lying position is supported from the back (horizontal direction) by the longitudinal direction main body part 15, The recumbent posture can be easily maintained while suppressing the pressure applied to each part of the human body.

  Further, in this lying down posture mattress 10, concave core materials 21, 22, 23 having shapes corresponding to the concave shapes of the concave portions 17, 18, 20 are bonded to the concave portions, respectively. , 23 is formed so as to form a flat continuous surface with the upper surface of the core body 11, so that it can fit the body shape of a user in a lying position and can support the human body, Thus, the durability of the mattress itself against repeated loads can be improved.

  Furthermore, in this lying down mattress 10, the hardness of the core materials 21, 22, 23 for the recesses is set to 40 to 90 N (JISK6400: D method), and the hardness of the core body 11 is set to 60 to While making 120N hard, the thickness of the core body 11 is 60 mm or more, the thickness for the shoulder upper arm portion of the core materials 21, 22, 23 for the recess is 30-50 mm, and the thickness for the heel portion is 10-30 mm, The heel part is thinner than the shoulder upper arm part by 15mm or more, so that it can cope with the load by the human body and the protruding amount of the human body, making it easier to shift to the lying position in either the left or right direction, and more pressing A more stable recumbent posture can be maintained by supporting the human back and body torso without giving a feeling.

  In the above embodiment, the shape of the concave portion and the core material for the concave portion to be fitted to the concave portion is illustrated and described as a rectangular parallelepiped shape. However, the shape is not limited to this, and other shapes may be used. Instead, the concave portion on the side in the center in the width direction may be an inclined concave portion that is deep at both ends, and a concave core material having a corresponding shape may be fitted.

  The dimensions of each part are based on the assumption that the user has a general physique. If the physiques are different, the dimensions may be changed as appropriate.

  Furthermore, although the case where the core main body is made foldable has been described as an example, it may be integrated.
