Nautilus has filed a patent for an adjustable barbell system that includes a base, weights, a handle assembly, an additional weight, and a selection assembly. The weights are grouped into two sets and supported by the base, while the handle assembly is fixedly joined to the weights. An additional weight is located distally of the handle assembly, and a selection assembly allows for the additional weight to be selectively engaged or disengaged from the handle assembly.

An adjustable barbell system has been described in a recently filed patent application (Publication Number: US20230293933A1). The system includes an adjustable barbell and a base that work together to provide a secure and convenient weight selection mechanism.

The adjustable barbell comprises a bar and a weight selector assembly. The weight selector assembly consists of a selector knob and a rod. The rod moves along the axial direction of the bar in response to the rotation of the selector knob. This movement allows the rod to engage a variety of removable weights, selectively coupling them to the bar based on the rotational position of the selector knob.

To ensure the safety and stability of the adjustable barbell, a locking mechanism is incorporated. This mechanism automatically locks the weight selector assembly, limiting the axial movement of the rod along the bar when the barbell is removed from the base. The locking mechanism includes a locking pin and a spring that biases the pin into engagement with the rod.

The patent application also describes additional features of the adjustable barbell system. It includes a first weight fixed to the bar and a plurality of removable weights that can be selectively coupled to the first weight based on the position of the rod along the bar. A pawl is attached to the distal end of the rod to prevent the extension of the rod beyond the face of a removable weight when it is not interlocked with another weight.

The base of the adjustable barbell system plays a crucial role in the functionality of the weight selector assembly. It automatically unlocks the weight selector assembly for adjustment when the barbell is placed on the base. This is achieved through a lock disengagement pin that actuates the locking mechanism to unlock the rod.

Overall, this adjustable barbell system provides a convenient and secure way to adjust the weight selection during workouts. The combination of the weight selector assembly, locking mechanism, and base ensures ease of use and safety for users.
