A recently granted patent (Publication Number: US11771942B2) describes a system for adjusting the weight of a dumbbell used for gymnastic exercises. The system includes a supporting frame and at least one dumbbell with a handgrip that can rotate around an axis. The dumbbell has a first plurality of weights that can be individually locked or unlocked at the first end of the handgrip using first locking means, and a second plurality of weights that can be individually locked or unlocked at the second end of the handgrip using second locking means.

The system is characterized by the inclusion of at least one actuating device on the supporting frame. This actuating device is responsible for causing the rotation of the handgrip from a locking position to an unlocking position and vice versa. This allows the user to select the desired weight to be locked or unlocked for their gymnastic exercise.

Additionally, the system includes a logic control unit that can send control signals to the actuating device. This control unit can also be connected to a remote device, enabling the system to receive signals corresponding to weight adjustments.

The dumbbell in the system comprises a gear fixed to either the first or second end of the handgrip. This gear engages with the actuating device, which can include a motor and a worm screw. The gear is capable of engaging with the worm screw, causing the rotation of the handgrip from the locking position to the unlocking position and vice versa.

In an alternative embodiment of the system, the actuating device includes a motor, a first gear actuated by the motor, and a second gear actuated by the first gear. The gear on the dumbbell engages with the second gear, resulting in the rotation of the handgrip.

The system also includes lock/unlock pins that can engage with the dumbbell to prevent rotation of the handgrip when necessary.

In summary, the granted patent describes a system for adjusting the weight of a dumbbell used in gymnastic exercises. The system includes a supporting frame, a handgrip with multiple weights, and actuating devices for controlling the rotation of the handgrip. A logic control unit and the ability to connect with remote devices enhance the functionality of the system.
