Latest Patents

One of Johnson's latest patents is the "Retractable Ramp System for a Mobility Vehicle." This system features a ramp platform that is driven by a reversible motor, along with an associated drive pulley and drive belt affixed to a ramp carriage assembly. A spring-loaded mechanical release assembly is utilized to engage and disengage the drive pulley from the motor. Additionally, a manual control assembly allows for manual deployment of the ramp when the drive pulley is disengaged. The ramp flap provides a smooth transition between the ramp platform and the mobility vehicle, supported by wheels that translate along the ramp platform. Linear bearing blocks facilitate the movement of the ramp platform along guide shafts during deployment and stowage.

Another notable patent is the "Power Door Latch Method and Apparatus." This invention eliminates the need to slam a door while allowing a two-stage lock to engage. The OEM striker, once engaged, is driven toward the door frame in a linear motion by a reversible electric motor that operates an acme screw within the drive housing. Adjustable limit switches detect full closure and full open positions to activate and deactivate the motor. A mechanical delay is incorporated to ensure the engagement of the two-stage lock mechanism. This power door latch can be used with any OEM striker in most vehicles and can also be manually engaged in the event of a power failure.
