(under the class definition) Device comprising a self-supporting frame, provided with a buttock support, for assisting a person in learning to walk; or for supporting skaters or ambulant invalids in a standing position.
(1) Note. In general, walker and skater frames are elsewhere, depending on the mode of use. Perfecting features may result in classification elsewhere, as indicated by the search notes below. The addition of a seat compels classification in this class (297). However, see the Search Class notes below for the line between Class 280 and Class 297.

135, Tent, Canopy, Umbrella, or Cane,
67, for walkers, per se, (i.e., without seats, wheels, or path control), operable by lifting from, moving across, and replacing on the ground, floor, or the like.
280, Land Vehicles, 7.1, for wheeled walkers propelled by seat occupants and convertible to a different device, such as a stroller, subclasses 43+ for walkers having retractable wheels; subclasses 87.051 for wheeled walkers propelled and steered by seated occupants; and subclasses 809+ for skaters' appliances and attachments. Class 280 is superior to Class 297, and a vehicle feature in these devices (see the note to Class 280 in the class definition of Class 297) will result in classification there, except that the further inclusion of means exterior of the device restricting its travel to a predetermined path makes it an amusement device or an exercise device for placement elsewhre.
472, Amusement Devices,
1+, for a skater or walker supporting roundabout restricted to a circuitous path, particularly subclasses 14+ for an occupant propelled roundabout and subclass 15 for a trainer for foot travel.
482, Exercise Devices,
51+, for an exercise device which may support a skater or walker, particularly subclasses 66+ for an occupant-propelled support frame having a movement facilitating feature, e.g., a runner, wheel, etc., for foot travel and subclass 69 for an exercise device for suspending the occupant from above, e.g., a body harness, etc., for foot travel.
