US Patent 11766734 Welding carts with tool-less securing systems

Welding carts with tool-less securing systems are disclosed. In some examples, a welding cart may be configured to retain and/or transport a welding-type power supply. The cart and power supply may have bracket holes configured to receive bracket ends of a securing bracket. The bracket ends may be received by the bracket holes when a shaft retaining the securing bracket is engaged with a rotational lock of the cart. An actuator connected to the shaft may be configured to rotate the shaft to engage the rotational lock. A resilient member may bias the bracket ends out of the bracket holes when the shaft is disengaged from the rotational lock. A captive fastener attached to the shaft may ensure that the shaft and bracket remain captive to the cart even when the shaft is disengaged from the rotational lock and/or the securing bracket is biased away from the cart.
