VEHICLES IN GENERAL
 B60

Note(s)

In this class, the term "vehicle" means all vehicles except those restricted to one of the following types of vehicles: rail vehicles, waterborne vessels, aircraft, space vehicles, hand carts, cycles, animal-drawn vehicles, and sledges; these types are to be found in the relevant classes B61-B64. Thus, the term "vehicle" embraces vehicular characteristics which are common to more than one of the above-listed types. It also embraces certain characteristics restricted to automobile or road or cross-country trailers. The following exceptions to the above should be noted:

  1. Sub-classes B60B and B60C embrace all vehicle wheels and tyres, except wheels for roller skates A63C 17/22, wheels for model railway vehicles A63H 19/22, and special adaptations of wheels or tyres for aircraft B64C 25/36.
  2. Sub-class B60C embraces the repairing of, and the connection of valves to, inflatable elastic bodies in general, and in this respect it is not limited to vehicles.
  3. Sub-class B60L embraces certain electric equipment of all electrically-propelled vehicles.
  4. Sub-class B60M embraces certain power supply equipment for, but external to, any kind of electrically-propelled vehicle.
  5. Sub-class B60S relates to all kinds of vehicles, except the servicing of rail locomotives B61K 11/00, ground equipment for aircraft B64F, or cleaning apparatus peculiar to waterborne vessels B63B 57/00, B63B 59/00.
  6. Sub-class B60T includes brake control systems of general applicability, and in this respect it is not limited to vehicles. It also includes rail-vehicle power-brake systems and some other features of rail-vehicle brake systems.
