1-4, an adjustable exercise device such as a barbell, kettlebell or dumbbell engages four groups of weight rings 20, 21, 30, 31 of a first dumbbell 2 and a second dumbbell 3. one or more (such as four) recesses 11 for mating and one or more (eg, four) recesses 11 formed between and in communication with the recesses 11 and located laterally of the weight rings 20, 21, 30, 31; It comprises a receptacle 10 comprising a plurality (eg four) of recesses 12, 13, 14, 15 and flanked by weight rings 20, 21, 30, 31 (Figs. 2, 3). Receptacle 10 includes one or more (such as four) passageways 16 that communicate with recesses 12 , 13 , 14 , 15 of receptacle 10 .

The dumbbells 2, 3 each include a handle mechanism 4, 5 engaged between weight rings 20, 21, 30, 31, the first and second handle mechanisms 4, 5 each having one or more (2 , etc.) having end housings 41, 42, 51, 52, which housings 41, 42, 51, 52 respectively include first and second weight members 60, 61 and first and second weight elements 62, 63, etc., housings 41, 42, 51, 52, respectively, within chambers 43, 53. It includes an extending projection 44 (FIGS. 6, 7) and one or more (such as two) locking notches 45 formed in projection 44 . One or more (such as four) latches 47 (FIG. 2) are engaged with the handlebars 40,50 and are extendable from the housings 41,42,51,52 and are attached to the weight rings 20,21,30,31. Engageable with weight rings 20, 21, 30, 31 for coupling to housings 41, 42, 51, 52 and handlebars 40, 50 as needed.

Weight members 60, 61 and weight elements 62, 63 (FIGS. 2, 6-7) each have a space 64 formed in a central portion, one or more (such as two) grooves 65 communicating with space 64, It includes one or more (such as two) compartments 66 that communicate with a groove 65 and communicate with each other at a central opening 67 . A pair of spring-loaded catches 70 are engaged in grooves 65 and are movable within spaces 64 of weight members 60, 61 such that weight elements 62, 63 and two arms 71 engage weight members 60, 61 and weights. Engaged within compartments 66 of elements 62, 63, each pulls catch 70 into groove 65 of weight members 60, 61 and weight elements 62, 63 (FIG. 7) and pulls catch 70 into weight members 60, 61 and 63, respectively. It includes one or first end 72 pivotally coupled to catch 70 for disengaging from space 64 of weight elements 62,63. Each of arms 71 includes another or second end 73 that engages openings 67 in weight members 60,61 and weight elements 62,63. When second end 73 of arm 71 is moved into compartment 66 of weight members 60,61 and weight elements 62,63 (FIG. 7), arm 71 moves catch 70 into groove 65 of weight members 60,61 and into groove 65 of weight members 60,61. It can be moved into the weight elements 62,63. Conversely, when second end 73 of arm 71 is released (FIG. 6), catch 70 is forced out of groove 65 and into space 64 of weight members 60,61 and weight elements 62,63. can be moved to

Carrier 80 is engaged with receptacle 10 (FIGS. 3-4, 6-7, 9-11) and passes from carrier 80 through passageway 16 into recesses 12, 13, 14, 15 of receptacle 10. One or more (eg four) poles 81 and one or more (4 one or more springs 83 in the carrier for moving the pole 81 and the stud 82 into the recesses 12, 13, 14, 15 of the receptacle 10 where the pole 81 is higher than the stud 82. 80 is engaged. A carrier 80 extends from the carrier 80 and includes one or more (eg, three) cams 84 arranged in a circle, each cam 84 including one or more (eg, two) seats 85, 86. .

An actuator 90 is engaged with receptacle 10 and is engageable with cam 84 . For example, receptacle 10 has recess 11, recesses 12, 13, 14, 15 and passageway 16 formed therein, and top panel 17 having one or more (e.g., three) curved slots 18. ( FIG. 3 ), actuator 90 guides actuator 90 to rotate relative to receptacle 10 and one or more (e.g., , three) protrusions 91 . A knob 92 may be coupled to projection 91 for securing actuator 90 to receptacle 10 and for rotating actuator 90 relative to receptacle 10 . Actuator 90 includes one or more (eg, three) projections 93 for engaging seats 85, 86 of cam 84 (FIGS. 12-14).

In operation, when projection 93 is separated from cam 84 (FIGS. 8-9, 12), pole 81 and stud 82 engage second end 73 of arm 71 and catch 70 into groove 65. upward to offset from the space 64 of the weight members 60,61 and weight elements 62,63. At this time, catches 70 are separated from projections 44 of housings 41, 42, 51, 52 (Fig. 7) and weight members 60, 61 and weight elements 62, 63 are separated from housings 41, 42, 51, 52 (Fig. 9). It does not have to be engaged. When the projection 93 of the actuator 90 is forced into engagement with the cam 84 or the first seat 85 of the cam 84 (FIGS. 10, 13), the carrier 80 is moved downwardly to move the stud 82 between the weight member 61 and the weight element. 63, the weight members 61 and weight elements 63 can be coupled to the housings 41, 42, 51, 52 (FIG. 10). When projection 93 of actuator 90 is forced into second seat 86 (FIGS. 11, 14) of cam 84, carrier 80 is moved further to move both pole 81 and stud 82 to weight members. Removed from 60, 61 and weight elements 62, 63, weight members 60, 61 and weight elements 62, 63 can be coupled to housings 41, 42, 51, 52 (Fig. 11). Rotation of actuator 90 actuates cam 84 to move carrier 80 downward relative to receptacle 10 to control engagement of pole 81 and stud 82 with weight members 60, 61 and weight elements 62, 63. only is required.

As described above, the present invention is not limited to the above embodiments, and can be implemented in various embodiments without departing from the spirit of the invention.
