Definitions

  • the invention relates to an exercise tool, such as dumbbells, barbells and kettle bells used in bodybuilding, weightlifting and other sports, more particularly to an exercise tool including a weight member that is safe to use.
  • Exercise tools such as dumbbells, barbells and kettle bells, are often used in bodybuilding and weightlifting.
  • Conventional dumbbells are formed using metal casting techniques, and the weight of a conventional dumbbell is controlled through the size thereof.
  • the conventional metal-cast dumbbell is disadvantageous in that, due to its rigidity, damage to a floor or injury to the user can occur when the dumbbell is accidentally dropped. Moreover, different molds are required to manufacture dumbbells having different weights, thereby resulting in high manufacturing costs. Furthermore, since it is difficult to control the amount of impurities in the raw material for making the dumbbells, the specific weight of the raw material can vary from one batch to another, thereby resulting in large errors in the actual weights of manufactured dumbbells.
  • an object of the present invention is to provide a weight member for exercise that can overcome at least one of the aforesaid drawbacks associated with the prior art.
  • Another object of the present invention is to provide an exercise tool that includes the weight member.
  • a weight member for exercise comprises a resilient shell that defines an inner chamber.
  • the inner chamber contains a filling having weighting and shock-absorbing properties.
  • an exercise tool includes a handle and at least one weight member for exercise.
  • the weight member comprises a resilient shell that is attached to the handle and that defines an inner chamber.
  • the inner chamber contains a filling having weighting and shock-absorbing properties.

  • the granules 41 , 42 are introduced into the inner chamber 22 via the hole 31 .
  • the shell 2 is then placed in a mold, and the assembly of the shell 2 and the granules 41 , 42 is heated to cause the foamable low specific weight granules 41 to swell, thereby resulting in the filling 4 that is contained in the inner chamber 22 .
  • the resultant filling 4 can have a form of a mixture of foamed low specific weight granules 41 and high specific weight granules 42 , at least one low specific weight foam body with high specific weight granules 42 dispersed therein, or a combination of both.
  • the assembly of the shell 2 and the filling 4 is then removed from the mold, and the hole 31 is closed with the use of the stopper 33 .
  • a desired weight for the weight member 100 can be achieved through mixing of suitable low specific weight and high specific weight materials in appropriate proportions, thereby dispensing with the need to use different molds to cast different sizes of products. It is thus possible to manufacture weight members 100 with precisely controlled weights at lower manufacturing costs.
