Description

  The present invention makes it possible to match the shape of the individual's head by overlaying the bags that can change the material and quantity of the pillow filling, and the combination as appropriate, and covering them with the cover of the bag skin. Related to pillows.

When a person lies down and sleeps, it is important to support the head firmly by filling the gap between the bedding and the body, especially the gap between the back of the head and neck.
Therefore, a pillow that supports the cervical vertebra support part and the head support part as independent bags has been proposed (see Patent Document 1), but it is more subtle due to the flexibility, smoothness, etc. of the filling to be packed inside the bag. The feeling of use of the pillow changes, and the quality and quantity of the filling must be changed in response to the change.

Japanese Patent No. 5115881

  Cover the inner bag body that can change the material used and the amount of pillow filling with the epidermis side surface to make the pillow adjustable in height according to the shape of the user's head and neck. In the pillow constituted by the above, since the amount of the filling to be packed in the small chamber constituting the inner bag body is changed, there is a margin in the filling amount as compared with the case where the filling is filled in the volume of the inner bag body 100%. As a result, the inner bag containing the filling in the surface of the epidermis becomes easy to move, and it is necessary to devise it so that it does not move.

The invention according to claim 1 is a pillow in which a plurality of middle bag bodies filled with filling are overlapped, and the overlapped intermediate bag bodies are covered with a common skin side surface, wherein the one inner bag body is a filling It is divided into a plurality of small chambers with a hook having an inlet / outlet, so that the fillings of the individual chambers can be filled and taken out, and the amount of filling in the small chambers can be selectively adjusted.
In the invention according to claim 2, the first inner bag body filled with the filling in the pillow according to claim 1 is formed integrally with the skin side ground, and on the (upper) one side of the first inner bag body, Create a space surrounded by the skin side, insert the second inner bag body into the space, and freely engage and disengage the second bag body and the first inner bag body with snap buttons placed in multiple places It is fixed to.
The invention according to claim 3 is the pillow according to claim 1, wherein the upper space 7 surrounded by the skin side ground is provided on each of the upper and lower surfaces of the first inner bag formed integrally with the skin side ground. A lower space is formed, a second inner bag body is inserted into the upper space, and an uneven profile sheet is inserted into the lower space as a body pressure dispersion adjusting layer made of urethane foam.

  The pillow according to the present invention is a pillow comprising a plurality of bags filled with fillings, and the overlapped bags are covered with a common skin side surface. Thus, the filling of each of the small chambers can be filled and taken out, so that the amount of filling or the quality of the filling in the small chamber can be arbitrarily changed according to the user's preference.

  In the pillow according to the present invention, the first bag filled with the filling is formed integrally with the skin side surface, and a space is formed on the upper surface of the first bag body to be wrapped with the surface side surface. Because the second bag body is inserted into the first bag body and the second bag body and the first bag body are detachably fixed by, for example, snap buttons arranged at the four corner corners and the center of the pillow long side, one-touch operation With this, you can easily perform a binding operation.

  Furthermore, in the pillow according to the present invention, a space surrounded by the surface side ground is formed on each of the front and back surfaces of the first bag body integrally formed with the skin side ground, and the second bag is included in one space. The pressure applied to the head because the body is inserted and the concave / convex profile sheet of urethane foam is inserted into the concave / convex shape on the upper surface (surface to which the weight of the head is added) in the other space. Is dispersed in the pillow so that it is difficult to be transmitted to the mattress.

The longitudinal front view of this invention pillow.

An example of implementation of the pillow of the present invention will now be described with reference to the drawings.
The pillow 1 of the present invention has the first and second inner bag bodies 3 and 4 formed by enclosing the filling 2 overlaid on the body pressure dispersion adjusting layer 5 and covered with the skin side surface 6, but the laminated state Is as follows. Centering on the first inner bag body 3, two spaces 7 and 8 surrounded by the skin side ground 6 are formed on both sides thereof, and the second inner bag body 4 is inserted into the space 7, In addition, an uneven profile sheet 9 made of polyurethane foam is inserted into another lower space 8 as a body pressure dispersion adjusting layer. The first and second inner bag bodies 3 and 4 are divided into small compartments 13 of appropriate capacity by the cloth 12 in order to adjust the type or amount of the filling 2 packed therein, and the filling and unloading ports are provided for each compartment. And a fastener 14 is provided for each.

When lying on the polyurethane foam, the weight of the head applied to the material surface is transmitted while the material is spread and dispersed in all directions and the force is attenuated in the thickness direction.
The force applied to the pillow placed under the head is transmitted directly to the bedding if the filling material in the pillow is hard. Inserting a sheet between the pillow and the bedclothes, the force applied if the sheet material is hard is transmitted downward as it is, but if it is soft, the force applied to the bedclothes below will be reduced and body pressure dispersion can be adjusted, This sheet is called a body pressure dispersion adjusting sheet.

  Then, the second middle bag body 4 inserted into the upper space 7 is provided with snap buttons 11 provided at a total of six locations, the four corners of the outer periphery and the two middle portions of the edge located in the longitudinal direction of the middle bag body 4. The snap button 11 provided at the corresponding position of the skin side ground 6 is fixed to the system. The means of tying up with the snap button 11 can be operated with a single touch and is easy, but it is difficult to detach and attach when the snap button 11 is too strong, which may lead to damage of the pillow fabric at the time of detachment. . Even if the snap button is removed and the skin and the side are displaced, as a means to adjust the slight pressure change accompanying the displacement, another layer of body pressure dispersion adjustment 5 is added to the inner bag consisting of two layers, and three layers are laminated. By making it a pillow, it becomes a pillow that reduces the pressure applied to the head and neck.

  The polyurethane foam is preferably a concavo-convex profile sheet, and reduces the pressure applied to the head and neck by using a three-layer laminated pillow as the body pressure dispersion adjusting layer 5.

Polyurethane foam is foamed with raw materials polyol and isocyanate as main components and mixed with foaming agents, foam stabilizers, catalysts, colorants, etc., and polyurethane foams with various properties are obtained, which are widely used in the field of the present invention. Has been. The characteristics are expressed in terms of hardness (N: Newton), density (kg / cm ³ ), rebound resilience (%), and the like, and are evaluated according to JIS K6401, JIS K7222, and JIS K6400.

The polyurethane concave-convex profile sheet 9 as the body pressure dispersion adjusting layer 5 is provided below the first inner bag body 3 and the second inner bag body 4, so that the first inner bag body 3 and the second inner bag body are provided. It is a member that disperses and adjusts the pressure change due to slight positional deviation, such as when the body 4 is misaligned or the snap button is detached and the epidermis and side ground are displaced. A sheet having a profile shape is preferred.
As an uneven profile sheet 9 made of polyurethane foam having a thickness of 10 to 30 mm and a hardness of 15 to 40 N at 25% compression in accordance with JIS K6401-2 (D method) when matching to the shape of the back and neck of an individual. And is used to disperse the pressure applied to the head and neck of the pillow via the first middle bag body 3 and the second middle bag body 4 at the top. The body pressure can be adjusted by combining the bag body 3, the second middle bag body 4 and the profile sheet 9.

  The pillow of the present invention does not feel a slight change in pressure transmitted to the head or neck through the first inner bag body 3 and the second inner bag body 4 at the top of the pillow when the head is placed on the pillow. Furthermore, the use of the pillow of the present invention reduces the way pressure is applied to the bedding located under the pillow, and affects the characteristics of the bedding that supports the weight of the entire body. This is a pillow that does not affect the sleeping comfort even if the bedding is changed with the same pillow.

When a person lays down sideways, he / she adds weight to the bedclothes at a ratio of 8: 33: 44: 15 to the head: chest: buttock: foot, and in a person with a weight of 60 kg, the head to the neck About 5 kg is applied to the pillow that supports the head, 20 kg to the chest, 25 kg to the buttocks, and 9 kg to the foot.
The head and chest are connected at the neck, and pressure is applied to the pillow and bedclothes at the head, and the chest, buttocks, and feet are deformed by adding the respective weight only to the bedclothes. The difference in the amount of deformation between the chest and the chest is a burden on the neck, and the balance between the sinking of the pillow and the bedclothes is important. You will feel the difference.

It is important that the pillow supports the weight of the head and fixes the cervical vertebrae. Although the pillow supports about 5 kg, the hardness at the time of 25% compression in accordance with JIS K6401-2 (D method) is 40-60N. Some degree of material is used.
On the other hand, as the bedding, a member that supports the whole body and has a hardness of about 50 to 130 N at 25% compression, which is harder than that used for a pillow, is used.

  In the present invention, a polyurethane foam sheet having a hardness of 15 to 40 N, which is 25% lower than the urethane foam material used for pillows and bedclothes, and having a thickness of 10 to 30 mm is arranged at the bottom of the laminated pillow, and the sheet is further provided. By arranging an uneven profile shape on the upper surface (surface where the weight of the head is added), the pressure received from the head is dispersed in the pillow so that it is difficult to be transmitted to the bedclothes.

  If the sheet surface is flat, when the load is received, the part sinks and at the same time the surrounding part is deformed by pulling in the part around the part that received the load, and the extension elastic force of the part changes the load part. The compressive elastic force of the load portion is affected, and the apparent compressive elastic force of the load portion is increased. This is due to the surface tension of the material, and it is a defect of the flat urethane surface called load diffusion. By applying uneven profile processing to the polyurethane foam, the urethane foam is proportional to the magnitude of the applied load. Deform. Therefore, the pillow is deformed by the magnitude of the load applied to the occipital region and the cervical vertebra part, and the pillow supports the occipital region and the cervical vertebrae as a pillow.

  Note that the urethane foam used in the present invention is not a so-called low-resilience urethane foam having a rebound resilience of about 5%, but a normal urethane foam having a 25% compression hardness of about 50 to 90 N that is easy to profile. preferable.
