  • Patent number: 11052946
    Abstract: A modular, reconfigurable frame that can be combined into multiple standardized segments to create different core vehicle configurations is described herein. The frame includes a plurality of components that affix together universally to make multiple versions of cycle, vehicle, and airframe styles. The reconfigurable frame includes a quick pin and fastener that allows for transportation platforms to be incorporated into the frame in a modular fashion.
    Type: Grant

  • Patent number: 8757651
    Abstract: A collapsible motorized two-wheeled cycle system features a two-wheeled cycle frame. The system features an upper hinge connected to a frame top horizontal member anterior component posterior end and a frame top horizontal member posterior component anterior end. A conical stiffener plug is located on the frame top horizontal member posterior component anterior end for snugly protruding into a conical stiffener plug aperture located on the frame top horizontal member anterior component posterior end. The system features a lower hinge connected to a frame bottom horizontal member anterior end and a frame anterior vertical member lower end. The system features a steering assembly located on a frame top horizontal member anterior end having a handlebar, a front fork, and a front wheel.

  • Patent number: 6075206
    Abstract: A low point drain for draining accumulated water from electrical conduit systems that are located in non-hazardous environments is disclosed. The drain includes a threaded coupling suitable for connection to a tapped opening in an electrical conduit, or a conventional "T" or elbow fitting or an electrical enclosure or junction box. The drain also includes an end cap attached to the other end of the coupling, a safety washer and a screen assembly that is retained within the end cap. The end cap has an interior lip that defines an opening through which the water may drain. The screen assembly includes a grommet that is held securely against the coupling end and a frustoconical screen that protrudes through the end cap opening. When the drain is installed at a low point in the conduit system, condensate that forms in the system flows out the drain aperture and screen by the action of gravity.
