DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reinforced rubber mat.

[0002]

2. Description of the Related Art There is a case where a rubber mat is laid on a road surface or a floor surface. This rubber mat is generally made of a single layer of synthetic rubber of the required thickness.

[0003]

Since the conventional rubber mat is a single-layer synthetic rubber as described above, the rubber mat has insufficient viscoelasticity and tensile strength, and when subjected to frequent loads, tears occur, resulting in poor durability. There were difficulties.

[0004] An object of the present invention is to provide a rubber mat which has solved the above-mentioned conventional problems.

[0005]

A for solving means] in order to achieve the above object configuration gist of the present invention, between the top sheet and the back sheet made of synthetic rubber, the reinforcing raw rubber overlaid nylon fabric on the front and back surfaces The sheet is integrated by pressure bonding with a sheet interposed therebetween, and non-slip projections are formed on the surface of the topsheet.

[0006]

According to the above construction, the viscoelasticity and the tensile strength are increased by the layer structure in which the reinforcing sheet of raw rubber on which the nylon woven fabric is laminated is interposed between the top sheet and the back sheet made of synthetic rubber. An object of the present invention is to provide a reinforced rubber mat which can prevent the occurrence and can be used for a long period of time.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2, reference numeral 1 denotes a rubber mat of the present invention. The rubber mat 1 is integrally press-bonded between a top sheet 2a made of synthetic rubber and a back sheet 2b with a reinforcing sheet 4 of raw rubber 5 having nylon woven fabrics 6a and 6b superposed on the front and back surfaces. This is a structure in which anti-slip projections 3 are formed on the surface of 2a.

As shown in FIG. 3, the rubber mat 1 is manufactured by arranging nylon woven fabric 6 on the front and back surfaces of raw rubber 5 having an appropriate thickness.
a, 6b are laminated, and this is laminated to a surface sheet 2 made of synthetic rubber.
a and the back sheet 2b are interposed and hot-pressed to obtain a reinforcing sheet 4 of a raw rubber 5 in which nylon woven fabrics 6a and 6b are superimposed on the front and back surfaces, and are pressed and integrated as a core material.

Since the present invention is a rubber mat having the structure as described above, the nylon woven fabric 6a and the nylon woven fabric 6a are provided on the front and back surfaces interposed between the top sheet 2a and the back sheet 2b made of synthetic rubber.
6b, the core material of the reinforcing sheet 4 of the raw rubber 5
It compensates for the difficulties of synthetic rubber, which has hardness but lacks viscoelasticity and tensile strength. It has less expansion and contraction than nylon woven fabrics 6a and 6b with two layers on the front and back, and has high viscoelasticity and tensile strength due to the elasticity of raw rubber 5. Become.

Further, when a reinforcing sheet 4 of raw rubber 5 having nylon woven fabrics 6a and 6b superposed on the front and back surfaces is interposed between a front sheet 2a made of synthetic rubber and a back sheet 2b, the raw rubber 5 is pressed. some infusible and have rows adhesive action between the surface sheet 2a and the back sheet 2b and to ensure the front surface sheet 2a, the crimping integration of three layers of reinforcing sheet 4 and the backsheet 2b.

An example of using the rubber mat 1 of the present invention will be described. In driving schools, driving schools, and the like, there is training on motorcycles such as straight bridge running (single bridge running). This is because when traveling at a low speed on a narrow road, the right and left balance is maintained without wobbling, and the skill of traveling safely at a low speed is acquired.

[0012] In the training of the straight bridge running, an iron straight bridge having a width of 30 cm, a length of 15 m, and a thickness of 5 mm is laid on the course surface, or a concrete straight bridge is placed on the course surface. I'm working on it. Therefore, the straight bridge made of iron is difficult to move and transport due to its weight, and causes slippage in rust corrosion and rainy weather. The straight bridge made of concrete requires driving work on the road surface of the course. In addition, there is a problem that the surface is worn.

Therefore, as shown in FIG. 4, by using the rubber mat 1 having the above-described structure according to the present invention for a straight bridge for training a motorcycle, the problem of the conventional straight bridge made of iron or concrete is solved. To eliminate.

Further, the rubber mat 1 according to the present invention can be laid on a wet ground at a construction site to prevent the wet ground from becoming muddy due to ingress and egress of a truck or the like. In this case, even if a load such as a frequently-moving truck is applied, the rubber mat 1
Ensure durability.

Further, by laying on the floor of the livestock barn, elasticity, prevention of slip, and insulation and heat insulation are increased,
It does not stress the livestock and prevents the deformation of the claws in the case of cattle and horses. In addition, the floor cleaning operation is facilitated and sanitary.

[0016]

As described above, the rubber mat according to the present invention is integrated by pressure bonding between a top sheet made of synthetic rubber and a back sheet with a raw rubber reinforcing sheet having a nylon woven fabric laminated on the front and back surfaces. Since the anti-slip projections are formed on the surface of the top sheet, the viscoelasticity and the elastic sheet layer structure of nylon woven fabric and raw rubber interposed between the top sheet made of synthetic rubber and the back sheet, It has the advantage of providing a reinforced rubber mat that has increased tensile strength, prevents the occurrence of tears, and withstands long-term use.
