Dumbbell assembly

Abstract

A dumbbell assembly includes a dumbbell unit having a handgrip portion, and a support base for seating the dumbbell unit thereon. The dumbbell unit has a handgrip portion and a carrying structure disposed movably above the support base. A user can raise the carrying structure to attach the handgrip portion and hold the handgrip portion and the carrying structure for carrying the whole dumbbell assembly by one hand.

1 . A dumbbell assembly comprising:
 a dumbbell unit including
 a connecting rod having a handgrip portion and two mounting portions at both ends of the handgrip portion, 
 a weight choosing structure assembled to each of the mounting portions, and 
 a plurality of weight discs selectively assembled with the weight choosing structure; 
   a support base having a loading side to permit seating of the weight discs thereon; and   a carrying structure including
 a retaining element abutting against the support base to prevent disengagement of the carrying structure from the support base, 
 a carrying element located above the loading side of the support base and movable relative thereto, and 
 a connecting element connected to the retaining element and the carrying element; 
 wherein, the carrying element is raised relative to the support base to fasten the handgrip portion. 
   
   
   
       2 . The dumbbell assembly as claimed in  claim 1 , wherein the cross-sectional surface of the mounting portion is a polygon in shape, the mounting portion penetrating through the weight choosing structure. 
   
   
       3 . The dumbbell assembly as claimed in  claim 1 , wherein the weight choosing structure includes a plurality of fixing elements parallel to one another, the mounting portion penetrating through the fixing elements respectively along the extension direction. 
   
   
       4 . The dumbbell assembly as claimed in  claim 3 , wherein the weight choosing structure includes a plurality of latching elements disposed in the fixing elements respectively. 
   
   
       5 . The dumbbell assembly as claimed in  claim 4 , wherein each of the latching elements includes a latching connecting element extending along an assembly direction and a constraining portion extending perpendicularly from the latching connecting element. 
   
   
       6 . The dumbbell assembly as claimed in  claim 5 , wherein each of the weight discs has a plugging groove to permit plug in of a respective one of the fixing elements therein. 
   
   
       7 . The dumbbell assembly as claimed in  claim 6 , wherein the plugging groove in each of the weight discs has a first side extending along the assembly direction and formed with a blocking groove for receiving the constraining portion when the weight disc is fixed to the weight choosing structure. 
   
   
       8 . The dumbbell assembly as claimed in  claim 7 , further comprising a heavy weight disc corresponding to the second side having a second blocking groove. 
   
   
       9 . The dumbbell assembly as claimed in  claim 1 , further comprising a heavy weight disc having a thickness greater than that of the light weight disc. 
   
   
       10 . A dumbbell base for positioning a dumbbell having a handgrip portion and a plurality of weight disc, the dumbbell base comprising:
 a support base having a loading side to permit seating of for the weight disc positioning thereon; and   a carrying structure including
 a retaining element for preventing disengagement of the carrying structure from the support base, 
 a carrying element movable with respect to the support base and located above the loading side of the support base, and 
 a connecting element connected to the retaining element and the carrying element; 
   wherein the carrying element is raised to fasten with the handgrip portion.   
   
   
       11 . The dumbbell base as claimed in  claim 10 , wherein the retaining element extends from the connecting element. 
   
   
       12 . The dumbbell base as claimed in  claim 10 , wherein the carrying element has an attachment surface complementing with the handgrip portion. 
   
   
       13 . The dumbbell base as claimed in  claim 10 , wherein the support base has a bottom surface formed with a cavity, the retaining element being received in the cavity. 
   
   
       14 . The dumbbell base as claimed in  claim 13 , wherein the loading side of the support base has a through hole communicating with the cavity, the connecting element being moveably disposed in the through hole.
