Adjustable exercise device

Abstract

An adjustable barbell or dumbbell or exercise device includes a handle device having a handle bar engageable into grooves of a number of weight members, a number of plates disposed on the handle bar and each having an engaging element for engaging with tongues of the weight members when the plates and the hand grip are rotated relative to the handle bar, and for anchoring a selected number of weight members to the handle bar with the plates, and a detecting device includes a displayer electrically connected to a central processing unit for displaying an information, and a switching device includes one or more weight detecting switch elements electrically connected to the central processing unit for sending signals to the central processing unit.

1 . An adjustable exercise device comprising:
 a plurality of weight members each including a groove formed therein, and said weight members each including a tongue extended therefrom,   a handle device including a handle bar having an end portion selectively engageable into said grooves of said weight members, and a hand grip disposed on said handle bar,   a plurality of plates disposed on said handle bar and rotated in concert with said hand grip relative to said handle bar, said plates being selectively engageable between said weight members, and said plates each including an engaging element provided thereon for selectively engaging with said tongues of said weight members respectively when said plates and said hand grip are rotated relative to said handle bar, and for selectively anchoring a selected number of weight members to said handle bar of said handle device with said plates, and   a detecting device including a central processing unit, a displayer electrically connected to said central processing unit for sending signals to said central processing unit and for displaying an information, and a switching device having at least one weight detecting switch element electrically connected to said central processing unit for sending signals to said central processing unit.   
     
     
         2 . The adjustable exercise device as claimed in  claim 1  further comprising a base support having a plurality of socket openings formed therein for engaging with said weight members. 
     
     
         3 . The adjustable exercise device as claimed in  claim 2 , wherein said at least one weight detecting switch element of said switching device of said detecting device is disposed in either of said socket openings of said base support and directed toward either of said weight members. 
     
     
         4 . The adjustable exercise device as claimed in  claim 1 , wherein said detecting device includes a power switch member electrically connected to said central processing unit for actuating said central processing unit. 
     
     
         5 . The adjustable exercise device as claimed in  claim 1 , wherein said detecting device includes a circuit board engaged in said base support, and said at least one weight detecting switch element of said switching device of said detecting device is attached to said circuit board. 
     
     
         6 . The adjustable exercise device as claimed in  claim 1 , wherein said detecting device includes a displayer electrically connected to said central processing unit for information displaying purposes. 
     
     
         7 . The adjustable exercise device as claimed in  claim 1 , wherein said detecting device includes a coupler electrically connected to said central processing unit for signals inputting and outputting purposes. 
     
     
         8 . The adjustable exercise device as claimed in  claim 7 , wherein said coupler is selected from a universal series bus (USB). 
     
     
         9 . The adjustable exercise device as claimed in  claim 1 , wherein said detecting device includes a battery electrically connected to said central processing unit for energizing said central processing unit. 
     
     
         10 . The adjustable exercise device as claimed in  claim 1 , wherein said handle device includes a shank for engaging into said grooves of said weight members and for anchoring said housing to said weight members and for preventing said housing from rotating relative to said weight members. 
     
     
         11 . The adjustable exercise device as claimed in  claim 10 , wherein said handle device includes a follower disposed between said plates and said hand grip and rotated in concert with said plates and said hand grip relative to said handle bar, said follower includes a plurality of flaps extended therefrom and spaced from each other for forming a plurality of notches between said flaps, said shank includes a window formed in said shank, and said follower includes a plurality of ears for selectively aligning with said window of said shank, and said ears each include a numeral for being shown through said window of said shank. 
     
     
         12 . The adjustable exercise device as claimed in  claim 11 , wherein said handle device includes a housing rotatably engaged on said handle bar, and said housing includes a spring biased latch for selectively engaging with either of said notches of said follower and for preventing said follower from being rotated relative to said housing, and said housing includes a casing having a compartment formed in said casing for slidably engaging with said spring biased latch. 
     
     
         13 . The adjustable exercise device as claimed in  claim 12 , wherein said housing includes a spring biased projection engageable with said follower for anchoring and positioning said follower to said housing at selected angular positions.
