Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a mat for physical education.

[Conventional technology]

As a conventional technology for sports mats, for example,
There are those shown in Fig. and Fig. 6. This sports mat has a cushion material 21 such as polyethylene sponge or polyurethane foam inserted inside an outer bag 20 made of canvas.

The outer bag 20 is formed into a bag shape by sewing two pieces of cloth, an upper cloth 22 and a lower cloth 23, together, and an opening 24 that can be opened and closed is formed in the lower cloth 23. The cushion material 21 is inserted therein.

[Problem that the invention attempts to solve]

By the way, as shown in FIG. 7, the conventional outer bag 20 is made by overlapping the side edges of notches 25 formed at the four corners of the upper cloth 22 and sewing them along the chain line A. As shown in FIG.
The peripheral edges of 3 are overlapped and sewn together, and then turned inside out.

Therefore, when the cushion material 21 is inserted inside the outer bag 20, as shown in FIG.
2 and the sewn edge 26 of the lower cloth 23 are the cushion material 21
The pine often rises along the side of the pine, and this rise causes a bulge at the bottom of the side of the pine, so when multiple pine are laid together, the 6th
As shown in the figure, there is an inconvenience that a gap L is created between adjacent mats.

Therefore, the technical objective of this invention is to solve the above-mentioned inconvenience and to prevent gaps from forming between the pine mats when they are laid.

[Means for solving problems]

In order to solve the above problems, this invention covers the outer periphery of the surface, side and lower surfaces of the cushion material with an upper cloth, and the periphery of the lower cloth that covers the central part of the lower surface of the cushion material. The structure is such that the sewn edges of the upper and lower fabrics are located on the outer periphery of the lower surface of the cushion material.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

〔Example〕

As shown in FIGS. 1 and 2, the mat for physical education according to this invention consists of an outer bag 1 and a cushion material 2 inserted into the outer bag 1, and the cushion material 2 is made of polyethylene. It is made of foam such as sponge or polyurethane foam.

The outer bag 1 is made into a bag by sewing the peripheral edge of a lower cloth 4 that covers the central part of the lower surface of the cushion material 2 to the peripheral edge of an upper cloth 3 that covers the outer periphery of the upper, side, and lower surfaces of the cushion material 2. Yes, the lower cloth 4 has an insertion hole 5.
is formed, and the cushion material 2 is inserted into the interior through the insertion opening 5.

As shown in FIG. 3, such an outer bag 1 is made by cutting the four corners of the upper cloth 3 diagonally, forming a notch 7 in the center of the slanted edge 6, and cutting both sides of the notch 7. are overlapped with each other and sewn along the chain line A, and then the sloped edges 6 that continue on the side edges are overlapped and sewn together, and then the lower fabric 4 is attached to the peripheral edge of the upper fabric 3 as shown in FIG. The periphery of the fabric 4 may be overlapped and sewn, and then turned inside out through the insertion opening 5 formed in the lower fabric 4.

A lid 8 is attached to one side edge of the insertion opening 5, and a hook-and-loop fastener 9 is attached to the tip of the lid 8 and the other side edge of the insertion opening 5. The insertion port 5 can be opened and closed by loosening and removing the hook-and-loop fastener 9.

Further, a connecting piece 10 is attached to two outer peripheral sides of the outer bag 1, and a surface fastener 11 that can be engaged with the tip of the connecting piece 10 and the remaining two sides of the outer bag 1.
is attached, and the hook-and-loop fastener 11 of the connecting piece 10
By engaging the surface fasteners 11 of adjacent mats, the mats can be interconnected, as shown in FIG.

Such a connecting piece 10 may be attached to the outer periphery of the lower surface of the outer bag 1, as shown in the figure, or may be attached to the outer periphery of the upper surface. The mounting position of the hook-and-loop fastener 11 is considered in accordance with the mounting position of the connecting piece 10.

〔effect〕

As described above, according to this invention, the outer bag is formed by sewing the outer edge of the lower fabric to the outer edge of the upper fabric that covers the outer circumference of the upper, side, and lower surfaces of the cushion material. By inserting the cushion material into the inside of the mat to form a mat, the sewn peripheral edges of the upper and lower fabrics are located on the outer periphery of the lower surface of the cushion material, and as a result, the sides of the mat are held flat. Can be done. Therefore, by laying a large number of mats flat, the side surfaces of adjacent mats abut each other, and it is possible to prevent gaps from forming between adjacent mats.
