Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention is applicable to mats, chair cushions, car cushions,
The present invention relates to a plastic-filled attendant mat with a novel internal structure that can be used as a seat, a mattress, a rug, etc.

<Prior Art> Conventionally, many of the above-mentioned mats are filled with an elastic material such as cotton, rubber, or soft plastic foam. Further, in order to stimulate the contact area on the body, it was necessary to provide irregularities on the surface of a slightly hard foam (for example, urethane foam).

<Problems to be Solved by the Invention> The conventional structure described above has the disadvantage that although it can be folded, it cannot be rolled up.

Means for Solving the Problems> Therefore, in the present invention, at least two skin materials (one
) (1) A plastic-filled attendant mat has been developed which has a structure in which a large number of small bags (2) are formed between the two, and a large number of hollow plastic elastic pieces (3) are housed in the small bags as fillers.

Function> The plastic-filled attendant mat having such a structure can be folded as well as rolled up, since the individual pouches within the mat maintain their freely deformed shapes.

<Example> Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a plan view of a mat that is an embodiment of the present invention, and FIG. 2 is an enlarged sectional view of the same essential parts. As is clear from this example, the product of the present invention has at least two skin materials (1) (
1) It has a structure in which a large number of small bags (2) are formed between them, and a large number of hollow plastic elastic pieces (3) are housed as fillers in the small bags. The skin material (1) is a commonly used cloth or synthetic leather, and the method of forming the pouch (2) is by weaving such as bag weaving, or by partitioning it into a pouch by heat-sealing or gluing. Furthermore, a quilted structure may be considered.

Alternatively, a hollow plastic elastic piece (3) placed in a net-knitted inner bag may be placed in a small bag (2) partitioned by the skin material (1) to form a double structure.

The present invention is not limited to the above example, but can be applied to structures as described below. That is, FIG. 3 is a perspective view of the car cushion, and FIG. 4 is a perspective view of the sheet. FIG. 5 is a perspective view of the lug.

FIG. 6 is a perspective view showing an example of a hollow plastic elastic piece, and FIG. 7 is a longitudinal sectional view at the center thereof. As seen in this example, the hollow plastic elastic piece (3) is made of plastic, as its name suggests, and has a hollow chip structure. The diameter is approximately 8 m, the length is approximately 10 mm, and the wall thickness is approximately 0.7 m. What is its shape?

In addition to pipe-shaped chips, spring-shaped chips as shown in FIGS. 8 and 9 are also conceivable. In addition, FIG. 8 is a perspective view, and FIG. 9 is a longitudinal cross-sectional view at the center thereof. Such a structure has the elasticity to become smaller in diameter when a load is applied from above and below or from the left and right, but to return to the original diameter when the load is removed. In addition, in order to keep the repulsive force against the load within the required range, it is possible to change the thickness of the hollow plastic elastic piece (3), or to make it an ellipse so that it can be shaped vertically and horizontally depending on the position where the force is applied. They can also have different elasticities. Furthermore, deformation due to the action of force can be kept within a predetermined range. In order to do this, it is necessary to provide a protrusion on the outer surface of the hollow plastic elastic piece (3) so that when an excessive load is applied, one edge of the spiral structure comes into contact with this protrusion to prevent further deformation. A similar effect can also be obtained by providing the inner surface of the filler. To reduce the temperature rise, it is recommended to apply fragrance, insect repellent, deodorizer, etc. to such a hollow chip to emit aroma, or to provide a heat reflective film such as aluminum plating on the surface. , making the use of the mat more comfortable.

<Effects of the Invention> Since the plastic-filled attendant mat of the present invention has the above-described structure, the individual pouches within the mat maintain the shape as they are freely deformed, so the shape can be changed during use; The finger pressure can be adjusted freely, and it can be folded or rolled up for storage. Since the above-mentioned special filler is used inside the mat, it can also be used as a healthy mat that stimulates the skin. Good ventilation and hygiene.
