Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a mat for ventilation such as bedding and a seat.

[0002]

[Prior art]

 Conventionally, mats made of sponge or the like are often used as mats for beds and futons or mats for seats. However, because of poor ventilation, it is difficult to evaporate even if you sweat, and your back and buttocks tend to get stuffy and you cannot sleep comfortably.

[0003]

[Problems to be solved by the invention]

 Therefore, the present invention has a good air permeability and can evaporate immediately even if sweating, and the contact part with the body is hardly stuffy, so that it can sleep comfortably or maintain a sitting state. It is an object of the present invention to provide a ventilation mat.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the ventilation mat for bedding and seats of the present invention is formed into a plate-like shape by bending a large number of plastic linear members 2 into a scaly shape and bonding the contact portions with each other. A mat body 1 having a three-dimensional net-like structure is formed by stacking, and a hole 3 opening to an end face is provided inside the mat body 1.

[0005] The ventilation mat for bedding and seats of the present invention described above extrudes a die 5 in which a plurality of orifices that open downward are arranged in a planar manner so that a blank portion exists at a required location. The extruder continuously extrudes the thermoplastic resin in a fluid state from each orifice of the die 5 to form a large number of linear bodies 2 and hangs the linear bodies 2 in a molten state. The lower position of the orifice blank portion 6 of the die 5 described above is drawn while taking into account the lower speed of the orifice blank 6 while taking into contact with each other using its tackiness by bending it into a hollow shape by pulling it down while keeping its plasticity. The mat body 1 is formed while accumulating in a three-dimensional net shape at locations except for the holes, and a hole 3 is formed at a position below the orifice blank portion 6, and then the mat body 1 having the hole 3 is cooled and solidified. It is preferably obtained by cutting to a required length after the formation.

【Example】

 Hereinafter, the illustrated embodiment of the present invention will be described. First, in the figure, reference numeral 1 denotes a mat body. The mat body 1 is formed into a three-dimensional net-like structure by bending a large number of linear bodies 2 made of plastic such as polypropylene into a tabular shape and bonding them together in a plate shape while adhering their contacting parts. . The inside of the mat body 1 is provided with a plurality of holes 3 opening to the end face. The length and width of the mat body 1 can be set to appropriate dimensions according to the application, and the thickness of the mat body 1 is preferably about 20 mm to 60 mm. Further, the wire diameter of the linear body 2 is preferably about zero commas several mm to several mm. Further, the shape of the hole 3 provided in the mat body 1 is arbitrary, and can be a circle as shown in FIG. 1, a triangle as shown in FIG. 2, a rectangle as shown in FIG. The number and arrangement of the holes 3 are also free.

Next, FIG. 4 shows a manufacturing process of the mat of the present invention. In the figure, reference numeral 5 denotes an extruder die, which has a plurality of orifices opening downward. The orifices are arranged so as to have a blank portion at a required position in a plane, and reference numeral 6 in the drawing indicates a blank portion in the die 5 where no orifice is present. The extruder heats and melts a thermoplastic resin such as polypropylene, and continuously extrudes the resin having the fluidity from the orifice of the die 5 to a lower position to form a large number of linear bodies 2 and hang down. Next, at a position below these linear bodies 2, while these linear bodies 2 are still plasticized in a molten state, they are pulled at a speed lower than their falling speed. That is, the linear body 2 is received on the upper surface of the take-up roll 7 disposed below the die 5, and the take-up roll 7 is taken up while rotating at a speed lower than the falling speed of the linear body 2. As a result, each linear body 2 bends in a rotting shape, and the respective linear bodies 2 are integrated in a three-dimensional net-like shape while bonding their contacting parts by using their adhesive properties, whereby the mat body 1 is formed. You. However, in the die 5, as described above, the linear body 2 does not descend, and the linear body 2 does not accumulate in a three-dimensional net shape. Is formed. The mat body 1 having the holes 3 is completed by cooling and solidifying by dipping in cooling water 8 or the like, pulling it up, drying it, and cutting it into an appropriate size and shape.

[0008]

[Effect of the invention]

 The mat for ventilation of bedding, seat and the like according to the present invention as described in claim 1 is as described above. , The air permeability is extremely good. Further, since the holes 3 are provided inside the mat body 1, the air permeability is synergistically improved. Since the holes 3 are provided, there is also an advantage that the mat body 1 can be cleaned from the inside by inserting a cleaning pipe or the like into the holes 3 and ejecting hot water or steam from the cleaning pipe or the like. As described above, the ventilation mats for bedding and seats of the present invention have extremely good ventilation as described above.For example, they can be laid under a futon or laid on a seat and then laid or laid on top of them. If you sweat, you will evaporate immediately, and there will be no stuffiness in contact with the body, so you can sleep comfortably and keep sitting in your seat. In addition, the ventilation mat of the present invention according to the second aspect of the present invention can be manufactured extremely efficiently, so that the cost can be reduced.

Claims (1)

[Utility model registration claims] 1. A mat body 1 having a three-dimensional net-like structure is formed by bending a large number of plastic linear bodies 2 into a scalloped shape and bonding them to each other while adhering mutually contacting portions to form a mat body 1 having a three-dimensional net-like structure. A ventilating mat such as a bedding and a seat having a hole 3 opened to an end face inside a main body 1. A die 5 having a plurality of downwardly opening orifices arranged in a planar manner so as to have a blank portion at a required position is attached to an extruder, and the extruder causes the thermoplastic resin in a fluid state to flow.
