It is related with the buffer mat for gymnastics used widely.
  • Conventional gymnastic cushion mats are generally employed in which a foaming synthetic resin cushioning material is accommodated in a cover sheet made of turbolin or canvas (for example, Japanese Patent No. 2595486, Japanese Patent Laid-Open No. Hei. 11-76452 and JP-A-11-244412).
  • the conventional cushion mat is heavy when the cushioning material is made of foamed synthetic resin, but is made of a size having an area for safely receiving the body of Jim Nast. For this reason, a labor is required for conveyance work and arrangement work. In addition, since the resilience against bending is high, it cannot be folded during storage and takes up storage space.
  • the conventional mat cannot adjust the impact resilience, and the strength of the cushion mat is also due to the aging deterioration of the cushioning material. The decrease in elastic force is inevitable.

  • the rebound resilience can be freely controlled by adjusting the air pressure in the mat body, and the rebound resilience suitable for the age of the user and the content of the game can be obtained. Moreover, the desired resilience can be reproduced any number of times. In addition, since it is lightweight and the resilience disappears when air is discharged, it can be folded freely, making it easy to carry and reducing the storage space.

Further, when a brushed sheet is used as the exterior sheet, a mat having a good touch feeling can be obtained. Further, if the exterior sheet is attached to the mat body via an auxiliary sheet, an exterior sheet having poor adhesion to the mat body can be used.
