Adjustable handles as well as assemblies incorporating the same

A rolling assembly configured to transition from a closed condition where it is folded up to an open condition where it is expanded for use, the rolling assembly comprising:

• a frame configured to transport one or more objects and forming a compartment having a front wall, a rear wall, a right sidewall, a left sidewall, and a bottom wall;
• 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 a button cap and at least one push-button arm, the at least one push-button arm is located beneath the button cap and configured to actuate the spring-loaded gear,
• 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 condition and a locked condition,
• 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 housing 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 button cap as the at least one push-button arm traverses through the at least one or more aperture of the housing wall,
• the second compartment having a proximate end and a distal end,
• the second compartment comprising a handle gear hub at the distal end with a plurality of shaft teeth formed on a surface thereof and radially disposed about the push-button axis, the handle gear hub is configured to receive the spring-loaded gear and removably engage the plurality of shaft teeth with the plurality of gear teeth, the second compartment is adapted to rotatably receive the base member at the proximate end of the second compartment,
• 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 substantially the same dimensions as the handle gear hub and is configured to receive the spring-loaded gear and removably engage the plurality of base-member teeth with the plurality of gear teeth.

A rolling assembly comprising:

• a frame comprising a frame bottom wall and 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;
• 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 a button cap and at least one push-button arm, the at least one push-button arm is located beneath the button cap and configured to actuate the spring-loaded gear,
• 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 housing 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 button cap button as the at least one push-button arm traverses through the at least one or more apertures of the housing wall,
• the second compartment having a proximate end and a distal end, the second compartment comprising a handle gear hub at the distal end with a plurality of shaft teeth formed on a surface thereof and radially disposed about the push-button axis, the handle gear hub is configured to receive the spring-loaded gear and removably engage the plurality of shaft teeth with the plurality of gear teeth, the second compartment is adapted to rotatably receive the base member at the proximate end of the second compartment,
• 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 substantially the same dimensions as the handle gear hub and is configured to receive the spring-loaded gear and removably engage 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 housing wall, and in turn, slidably moves the spring-loaded gear to the base 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 moves the spring-loaded gear to a predetermined position where a first section of the gear teeth at its distal end interlocks with the shaft teeth of the handle gear hub and a second section of the gear teeth at its proximate end interlocks with the base-member teeth of the base gear hub.
