CPC B62B 3/025 (2013.01) | 20 Claims |
1. A rolling assembly comprising:
a frame configured to transport one or more objects;
a plurality of wheel assemblies rotatably coupled to the frame, each of the plurality of wheel assemblies comprising a wheel; and
a handle assembly comprising a push button, a spring-loaded gear, a handle, and a base member,
the push button defining a push-button axis and comprising at least one push-button arm,
the spring-loaded gear comprising a gear shaft and a plurality of gear teeth, the spring-loaded gear is adapted to actuate between a released position and a locked position,
the handle comprising an arm extending substantially perpendicular to a handle shaft, the handle shaft having a first compartment and a second compartment separated by a retaining wall with one or more apertures, the first compartment and the second compartment are aligned along the push-button axis,
the first compartment is adapted to slidably receive the push button,
the second compartment comprising a gear hub with a plurality of shaft teeth formed on a surface thereof and radially disposed about the push-button axis, the gear hub is configured to receive the spring-loaded gear and interlock the plurality of shaft teeth with the plurality of gear teeth, the gear hub is positioned adjacent the retaining wall and in a distal end of the handle shaft, the second compartment is adapted to rotatably receive the base member at the proximate end of the handle shaft,
the base member coupled to the frame and comprising a base gear hub with a plurality of base-member teeth formed on a surface thereof and radially disposed about the push-button axis, the base gear hub is configured to receive the spring-loaded gear and interlock the plurality of base-member teeth with the plurality of gear teeth,
wherein, in the released position, the handle assembly is configured to allow rotation of the handle upon actuation of the push button, which moves the at least one push-button arm through one of the one or more apertures of the retaining wall, and in turn, slidably disengages the spring-loaded gear from the gear hub to allow the arm to freely rotate along the push-button axis; and
wherein, in the locked position, the handle assembly is configured to prevent rotation of the handle upon release of the push button, which slidably interlocks the spring-loaded gear to the gear hub.
