Strap-based variable modular cushioning material for use by tying

Abstract

A strap-based variable modular cushioning material for being tied on an object includes at least one strap and at least one block. The strap is formed with a plurality of through holes and can be wound around the object. The block is mad of elastic material, has at least one side concavely formed with a groove, and can deform and be inserted into at least one of the through holes of the strap to couple the block with the strap. When the block and the strap are coupled together, the inner wall of the through hole corresponds to the groove in position, and a top portion and a bottom portion of the block are exposed from the strap. When the strap is coupled with a plurality of blocks, each two adjacent blocks are separate from each other by a distance.

What is claimed is: 
     
         1 . A strap-based variable modular cushioning material for being tied on an object, comprising:
 at least one strap formed with a plurality of through holes and configured to be wound around the object; and   at least one block made of elastic material, having at least one side concavely formed with a groove, and configured to deform and be inserted into at least one of the through holes of the strap to couple the block with the strap, wherein an inner wall of the through hole corresponds to the groove in position and a top portion and a bottom portion of the block are exposed from the strap when the block and the strap are coupled together.   
     
     
         2 . The modular cushioning material according to  claim 1 , wherein the strap is coupled with a plurality of blocks, and each two adjacent blocks are separate from each other by a distance. 
     
     
         3 . The modular cushioning material according to  claim 1 , wherein an area of a top surface of the block is greater than a cross-sectional area of each of the through holes. 
     
     
         4 . The modular cushioning material according to  claim 1 , wherein a cross-sectional shape of each of the through holes is X-shaped. 
     
     
         5 . The modular cushioning material according to  claim 1 , wherein a cross-sectional shape of each of the through holes is formed by two intersecting slots, and an angle between the two slots is greater than 0 degree. 
     
     
         6 . The modular cushioning material according to  claim 1 , wherein each of the through holes has a circular shape. 
     
     
         7 . The modular cushioning material according to  claim 1 , wherein each of a front side and a rear side of the block is concavely formed with a groove. 
     
     
         8 . The modular cushioning material according to  claim 1 , wherein the groove is annularly and concavely formed on a periphery of the block. 
     
     
         9 . The modular cushioning material according to  claim 1 , wherein a middle portion of the block is columnar. 
     
     
         10 . The modular cushioning material according to  claim 1 , wherein the block is made of expandable polyethylene or ethylene-vinyl acetate copolymer. 
     
     
         11 . The modular cushioning material according to  claim 1 , wherein the strap is made of expandable polyethylene, a low-density polyethylene film, high-density polyethylene or nylon.
