Impact Absorption Possible Dumbbell and Barbell Disk

Abstract

The present invention relates to an impact absorbing dumbbell and an impact absorbing barbell disk. The impact absorbing dumbbell includes an outer cover prepared by cutting a flexible member into a dumbbell and sewing the cut flexible member, thereby having a dumbbell shape, a cylindrical tubular body installed inside the middle portion of the outer cover for serving as a handle and keeping the dumbbell shape, and weight constituent powder charged in the outer cover. The impact absorbing barbell disk includes an outer cover prepared by cutting a flexible member into a barbell disk and sewing the cut flexible member, thereby having a barbell disk shape, weight constituent powder charged in the outer cover, and a bushing made of metal or synthetic resin, the bushing being inserted and fixed in the central shaft hole of the outer cover.

1 . An impact absorbing dumbbell as an exercise implement, comprising: 
 an outer cover prepared by cutting a flexible member into a dumbbell and sewing the cut flexible member, thereby having a dumbbell shape;    a cylindrical tubular body installed inside a middle portion of the outer cover for serving as a handle and keeping the dumbbell shape; and weight constituent powder charged in the outer cover.    
   
   
       2 . The impact absorbing dumbbell as claimed in  claim 1 , wherein the cylindrical tubular body is installed to encompass the middle portion of the outer cover instead of being installed to be inserted in the outer cover.  
   
   
       3 . The impact absorbing dumbbell as claimed in  claim 1 , wherein the flexible outer cover is made of synthetic fabric, natural fabric, or synthetic rubber.  
   
   
       4 . The impact absorbing dumbbell as claimed in  claim 1 , wherein the cylindrical tubular body is made of synthetic resin, such as EVA or PVC, foam resin having high rigidity, or synthetic rubber.  
   
   
       5 . An impact absorbing barbell disk having a central shaft hole, serving as an exercise implement, comprising: an outer cover prepared by cutting a flexible member into a barbell disk and sewing the cut flexible member, thereby having a barbell disk shape; weight constituent powder charged in the outer cover; and a bushing made of metal or synthetic resin, the bushing being inserted and fixed in the central shaft hole of the outer cover.  
   
   
       6 . The impact absorbing barbell as claimed in  claim 5 , wherein at least two sheets of the flexible members having the same shape are sewn so as to overlap in order to divide an inner space of the flexible outer cover into a plurality of compartments, so that the weight constituent power is separately charged in the compartments.  
   
   
       7 . The impact absorbing barbell as claimed in  claim 5 , wherein the flexible outer cover is made of synthetic fabric, natural fabric, or synthetic rubber.  
   
   
       8 . The impact absorbing dumbbell as claimed in  claim 2 , wherein the flexible outer cover is made of synthetic fabric, natural fabric, or synthetic rubber.  
   
   
       9 . The impact absorbing dumbbell as claimed in  claim 2 , wherein the cylindrical tubular body is made of synthetic resin, such as EVA or PVC, foam resin having high rigidity, or synthetic rubber.  
   
   
       10 . The impact absorbing barbell as claimed in  claim 6 , wherein the flexible outer cover is made of synthetic fabric, natural fabric, or synthetic rubber.
