Description

[Detailed Description of the Invention] The present invention relates to a filling for pinerests used by patients and the like.

For example, patients who are bedridden at home for long periods of time, such as bedridden elderly people, and patients who require long-term hospitalization and treatment in hospitals, etc. must spend most of their lives on the floor, such as in bed. Therefore, the floor of such a bed is the place where the patient lives, and the pinerest that makes up the floor is one of the important elements that influences the patient's life.

If such a pinerest is too soft, the body will sink, making it difficult to change the position, making it uncomfortable to sleep, increasing fatigue, and reducing air circulation, which can cause bed marks. It is necessary to have appropriate compression hardness and flexibility, which are contradictory properties.

The present invention provides a filling for a pine tress, which has an extremely rational structure and can easily provide the above-mentioned antinomic cushioning properties and can effectively prevent deformation.

The following is a detailed description based on examples.

Reference numeral 1 denotes a box-shaped member integrally provided with a support plate portion 2 and side wall portions 3 surrounding both the front and back sides of the support plate portion 2, and the box-shaped member 1 is constructed of a semi-rigid plastic foam such as polyethylene foam.

Since the side wall portions 3 are provided around both the front and back sides of the support plate portion 2 as shown, the support plate portion 2 is supported by the side wall portion 3 at an intermediate position.

Therefore, the filling of the present invention is that in the box-like member 1, an appropriate cushioning material 4 which is flexible at least on the body contacting side is filled in the front and back spaces S surrounded by the support plate part 2 and the side wall parts 3. It is characterized by

The cushioning material 4 may be a flexible cushioning material such as a cushioning material made of soft plastic foam such as polyurethane foam or a cushioning material made of natural fiber such as needle cotton, or it may be made flexible at least on the side that comes in contact with the body. For example, in addition to these flexible cushioning materials, a harder cushioning material or the like may be laminated.

In such a configuration, the filling of the present invention can be used, for example, in the space S.
A pinerest can be constructed by covering the cushioning material 2 inside with an outer covering 5.

At this time, the cushion material 4 may be simply filled with
It may be fixed to the box-shaped member 1 with an adhesive or a fastener such as a button.

Alternatively, the entire filling may be wrapped in a thin plate made of soft plastic foam such as polyurethane foam and then covered with the outer sheath 5.

Of course, the padding of the present invention may be configured to cover the entire length of the body as shown in Figure 1a, or may be configured to correspond to parts of the body as shown in Figure 1A. suitable for etc.

However, the pine tress to which the filling of the present invention is applied is flexible on the body contacting side due to the cushioning material 4 filled in the space S of the box-shaped member 1, so it has a good texture and soft cushioning properties on the surface. , the support plate portion 2 of the box-shaped member 1 made of semi-rigid plastic foam supports the cushion material 4, and has an appropriate compression hardness as a whole;
It has so-called lumbar cushioning properties.

In particular, the present invention provides a flexible cushioning material 4 on both the front and back sides, so that both the front and back sides of the pinerest can be used as the body contact side, and the lower part of the support plate part 2 is always flexible and deformable. Although there is a cushion material 4 that is easy to bend, the support plate portion 2 is supported at an intermediate position by the side wall portion 3 as described above. 4, it is possible to effectively prevent the support plate portion 2 from falling or tilting due to compressive deformation of the cushion material 4.

Since the cushion material 4 is packed in the space S surrounded by the support plate part 2 and the side wall part 3, it cannot be pushed out outwardly.
It can effectively prevent misalignment, etc., and is unlikely to lose its shape even after long-term use.

Furthermore, since the periphery of the pinerest to which the filling of the present invention is applied corresponds to the side wall portion 3 of the box-shaped member 1, this portion is difficult to deform, and it is easy for a patient to sit on it when using it on a bed, for example.

In addition, in the case of the structure shown in Figure 1, in each filling, the side wall portion 3a corresponding to the body may be configured lower than the other side wall portions 3, or may be omitted to reduce the distance from the body. It can soften the hit.

The filling of the present invention includes the material and structure of the cushion material 4, the material of the semi-rigid plastic foam forming the box-shaped member 1,
The cushioning properties can be adjusted as appropriate by changing the thickness, foaming rate, etc., but in addition, the cushioning properties can be adjusted as appropriate by providing a large number of appropriate uneven portions A on the support plate portion 2, as shown in Figure 3, c. can also be adjusted.

Here, the shape of the concave and convex portions A may be suitably wavy, lattice, or the like as shown in the figure, and the distribution density thereof may be suitably adjusted according to each corresponding body part.

In addition, the filling of the present invention configures the height L of the side wall portion 3 of the box-shaped member 1 to be equal to both the front and back sides of the support plate portion 2, and the space S
The cushioning material 4 to be filled in is equally configured on both the front and back sides,
It can be configured so that both the front and back sides have the same cushioning properties, or conversely, by making the height L different between the front and back sides, it can be configured so that the cushioning properties are different between the front and back sides.

Next, the filling of the present invention can significantly improve the air permeability of the front and back sides of the pine mattress by providing ventilation holes 6 that penetrate the front and back sides of the support plate part 2 at appropriate positions, numbers, and distribution densities.

Further, as described above, when the support plate portion 2 is provided with a large number of uneven portions A, lateral air permeability is improved, so by using such a structure in combination with the ventilation holes 6, better air permeability can be obtained. .

If such a ventilation hole 6 is provided in the recess 7, a large amount of air can be circulated through a funnel-like action.

Furthermore, if a ventilation hole 8 is also provided in the side wall portion 3, the air permeability in the front and back directions due to the ventilation hole 6 and the box-shaped member 1 due to the ventilation hole 8 are improved.
The ventilation inside and outside allows for very good ventilation as a whole.

As described above, the present invention has a box-like structure, at least on the body-contacting side, which is composed of a flexible cushioning material and a semi-rigid plastic fort having appropriate compression hardness, and side walls are integrally provided around both the front and back sides of the support plate. Because it has a structure that combines components in an extremely rational manner, it feels good on the surface and has soft cushioning properties against the body, and the overall compression is moderate, making it a cushion with a waist. It has the effect of having sex.

In particular, the present invention provides flexible cushioning material on both the front and back sides, so either the front or back sides of the pinerest can be used as the body contact side, and the lower part of the support plate is always flexible and easily deformed. Although the cushioning material is present, the support plate part is supported at an intermediate position by the side wall part, so that the support plate part is prevented from falling or tilting due to compressive deformation of the cushioning material, thereby providing a suitable sleeping comfort. There is an effect.

Furthermore, since the semi-rigid plastic foam member is configured in a box shape to hold the cushioning material, it is possible to extremely effectively prevent deformation due to long-term use.

Furthermore, the present invention has an extremely simple structure and has the effect of effectively improving air permeability.
