Therefore, the above is a description of each component of the adjustable weight dumbbell set 100 and its assembly manner according to a preferred embodiment of the present invention, and then its use characteristics are as follows:

When the user wants to adjust the weight of the dumbbell 20, if the weight 46 on the dumbbell 20 is to be selectively detached, the number of the weights 46 combined on the handle 30 is reduced, and the dumbbell is relieved. 20 weights.

First, the dumbbell 20 is placed on the top surface of the storage base 10 (as shown in the third figure), and the weights 46 on the dumbbell 20 are placed in the storage slots 121 of the storage base 10 ( As shown in the fourth figure, and while the weights 46 are in contact with the groove bottoms of the storage slots 121, the top pillars 13 on the storage base 10 pass through the action holes 416 of the dumbbells 20, so that The top post 13 pushes the brake block 412 to move from the braking position to the releasing position (ie, the braking block 412 originally located at the braking position is pushed by the spring 413 to be engaged in the braking groove 421 of the rotating plate 42, so that The handle 30, the turntable 42 and the selection plate 45 cannot rotate relative to the brake cover 41, but when the brake block 412 is pushed by the top post 13 to the release position, the brake block 412 is released from the brake groove. In addition to the 421, the grip 30, the turntable 42 and the selection dial 45 are rotated relative to the brake cover 41.

Then, the user can rotate the handle 30 on the storage base 10 to drive the turntable 42 to rotate relative to the brake cover 41, and determine the weight of the weight according to the weight value 422 appearing in the view window 414, and While the handle 30 drives the turntable 42 to rotate, the selection disk 45 is also rotated by the handle 30 to adjust the pressing unit 452 on the selection plate 45 and the weight on the weight 46. Forced block 465 relative position.

When the user selects the lightest weight, the forced block 465 of each weight 46 will correspond to the release gap 454 of the selection tray 45, so that the weight 46 at this time is not affected by the selection tray 45. The elastic member 462 is pressed against the outer tension position, so that the clamp 464 on the weight 46 cannot be clamped on the handle 30 for the user to use the handle 30 and the storage seat 10 . When separating, all the weights 46 will be placed in the receiving groove 121 of the storage base 10 (as shown in the seventh figure) to achieve the effect of adjusting to the lightest weight.

When the user wants to select one of the weights 46 of each weight unit 40 to be fixed to the handle 30, the handle 30 is also rotated on the storage base 10 so that the release gap 454 is originally corresponding to the selection tray 45A. Position of the forced block 465 on the counterweight 46A (as shown in the eighth figure) The rotation block 453 on the selection tray 45A is rotated to the corresponding position of the forced block 465 of the weight 46A (as shown in FIG. 9) by rotating the handle 30. The pressing block 453 pushes the forced block 465 to move inwardly, thereby interlocking the two blocks 461 against the elastic force of the elastic member 462, so that the two blocks 461 are moved from the outer position to the inner clamping position, so that the second The clamping block 464 on the block 461 can be clamped on the handle 30 (as shown in FIG. 9), and after the handle 30 is lifted out of the receiving seat 10, the weight 46A can be It is fixed on the handle 30 (as shown in the tenth figure) to achieve the effect of adjusting the weight.

When the user wants to select to fix the two weights 46 of the weight units 40 to the handle 30, the handle 30 is also rotated on the storage base 10 so that the release gap 454 is originally corresponding to the selection tray 45B. At the position of the forced block 465 on the weight 46B (as shown in FIG. 11), the pressing block 453 on the selection disk 45B is rotated to the weight of the weight 46B by rotating the handle 30. Positioning the corresponding block 465 (as shown in FIG. 12), the forced block 465 is pushed inwardly by the pressing block 453, and the two blocks 461 are interlocked to resist the elastic force of the elastic member 462. The two blocks 461 are moved from the outer tension position to the inner clamp position, so that the clamp 464 on the two blocks 461 can be clamped on the handle 30 (as shown in FIG. 12), and the After the handle 30 is lifted out of the accommodating seat 10, the weights 46B, 46A can be fixed on the handle 30 (as shown in FIG. 13) to achieve the effect of adjusting the weight.

When the user wants to select to fix the three weights 46 of each weight unit 40 on the handle 30, the handle 30 is also rotated on the storage base 10 so that the release gap 454 is originally corresponding to the selection tray 45C. At the position of the forced block 465 on the weight 46C (as shown in FIG. 14), the pressing block 453 on the selecting plate 45C is rotated to the weight of the weight 46C by rotating the handle 30. The corresponding block 465 is at a corresponding position (as shown in FIG. 15), so that the forced block 465 is pushed inward by the pressing block 453, thereby interlocking the two blocks 461 to resist The elastic force of the elastic member 462 causes the two blocks 461 to move from the outer position to the inner clamp position, so that the clamp 464 on the two blocks 461 can be clamped on the handle 30 (eg, After the handle 30 is lifted out of the accommodating seat 10, the weights 46C, 46B, 46A can be fixed on the handle 30 (as shown in FIG. 16), Achieve the effect of adjusting the weight.

Of course, since the weight 46 that is carried by the selection plate 45 is engaged by the rotation restricting member 47 in the clamping groove 463, and the brake block 412 is displaced by the spring 413, it is located at the braking position (ie, The brake block is engaged in the brake groove, so that the handle 30 and the brake cover 41 can no longer rotate relative to each other, so that the weight 46 can no longer rotate relative to the handle 30, and the configuration can be avoided. The weight 46 has its own separation.

In addition, since the pressing units 452 on each of the selection disks 45 are different in shape, that is, the pressing block 453 and the releasing gap 454 of each pressing unit 452 are not exactly the same in shape and can be rotated. The effect of adjusting the weight can be achieved by rotating the angle of the selection plate 45 to determine whether to press or release any of the weights, so that the weights 46 can be selectively assembled independently. The pedestal 10 is placed in the weight space 451 of the dumbbell 20 or out of the weight space 451. Therefore, the weighting state that can be adjusted by the present invention is quite diverse, and in addition to the weight state disclosed above, it can also be in other weighting states as shown in the seventeenth and eighteenthth drawings.

Therefore, the present invention can adjust the overall weight quite conveniently to meet the actual use requirements of the user or different users.

Secondly, when the user adjusts the weight of the weight, that is, the rotation of the handle 30 relative to the brake cover 41, so that each weight value 422 on the turntable 42 appears in the viewing window 414, the positioning The bead 434 of the group 43 will be subjected to the spring force of the spring 433 The pusher is partially slid into the positioning hole 431 so that the user can feel the appropriate rotational resistance and the dial 42 can be positioned at the correct angular position.

The above is only the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. All of the related art in the art will be equally changed according to the present invention. The scope of coverage.
