Description

  The present invention relates to a multi-purpose cover, and more specifically, for example, as a table tennis game fence by simply covering a screen-like frame portion formed to be used as a table tennis game fence, as a cold protection tool, a rug, etc. The present invention relates to a multipurpose cover having both functions.

  For example, in the case of a table tennis competition or a table tennis practice held in a gymnasium, it is usual to arrange a plurality of table tennis competition fences around the table tennis table in order to prevent mainly the scattering of table tennis balls.

  In a natural disaster such as the Great East Japan Earthquake, such a table tennis game fence may be used for the purpose of partitioning the place of evacuees when, for example, a gymnasium or the like becomes an evacuation center.

  In such a case, in the event of a natural disaster in the cold season, it is extremely important to take care of the refugees by shutting off the infrastructure immediately after that, and to care for the body becoming painful when sitting directly on a hard floor. .

  However, the conventional table tennis game fence is only for the purpose of preventing the scattering of table tennis balls, and is not suitable for applications such as a rug sheet for cold protection and cushioning.

  On the other hand, cold weather rug sheets that have been laid on the floor in the event of a natural disaster have also existed in the past, but such rug sheets are usually stored in warehouses and used only when natural disasters occur. There are many cases where the area is occupied and a disaster budget is required separately.

Patent Document 1 discloses a table tennis fence in which a bag-like cover is covered with a table tennis fixed fence that is framed in a quadrangular shape and can be erected by support legs (Patent Document 1, FIG. 5).
