Abstract
A rollator includes a collapsible frame supported on a plurality of wheels, a pair of handlebars, and a braking mechanism.
Claims18
A rollator for aiding mobility of a user, the rollator comprising:
- a frame;
- a plurality of wheels supporting the frame;
- a brake pad configured to selectively engage a first wheel of the plurality of wheels to resist movement of the rollator along a surface;
- and
- a brake handle operably coupled to the brake pad and configured to be moved out of a neutral position, in which the brake pad is disengaged from the first wheel, and toward a first fixed position, in which the brake pad applies a first force on the first wheel, or a second fixed position, in which the brake pad applies a second force on the first wheel that is greater than the first force.

A rollator for aiding mobility of a user, the rollator comprising:
- a left-side frame;
- a right-side frame coupled to the left-side frame;
- a seat supported between the left-side and right-side frames;
- a first handle assembly coupled to the left-side frame, the first handle assembly including:
- a first shaft extending upwardly from the left-side frame;
- a first handlebar extending rearwardly from the first shaft;
- and
- a first protrusion extending frontwardly from a portion of the first handle assembly;
- a second handle assembly coupled to the right-side frame, the second handle assembly including:
- a second shaft extending upwardly from the right-side frame;
- a second handlebar extending rearwardly from the second shaft;
- and
- a second protrusion extending frontwardly from a portion of the second handle assembly;
- a first elongated seat support coupled to the left-side frame;
- a second elongated seat support coupled to the right-side frame, the first and second elongated seat supports supporting the seat thereon;
- and
- a bag configured to detachably couple to either of:
- the first and second protrusions of the respective first and second handle assemblies;
- or
- the first and second elongated seat supports.

A rollator for aiding mobility of a user, the rollator comprising:
- a left-side frame;
- a right-side frame;
- a plurality of wheels supporting the left-side and right-side frames;
- and
- a folding mechanism coupling the left-side and right-side frames to one another and configured to transition the rollator between an expanded configuration and a collapsed configuration, the folding mechanism including:
- first and second cross bars pivotably coupled to one another and each having a first end, and a second end, the second end of the first cross bar being pivotably coupled to the left-side frame and the second end of the second cross bar being pivotably coupled to the right-side frame such that pivoting of the first and second cross bars relative to one another adjusts a width defined between the left-side and right-side frames;
- a first cam linkage pivotably coupled to the first end of the first cross bar and the left-side frame;
- and
- a first surface feature extending from the first end of the first cross bar and configured to lockingly engage the first cam linkage when the rollator is in the expanded configuration to selectively fix the rollator in the expanded configuration.
