CPC Definition - Subclass B66B
This place covers:
Transporting apparatus of the types specified herein for people or discrete loads when used in conjunction with buildings, complexes of buildings, mines, or similar scale manmade structures or natural formations (e.g. caves).
Elevating apparatus (i.e., elevators or lifts) for shifting a discrete load (e.g., person(s), freight), in its entirety, a significant distance (e.g., at least the height of a normal floor of a building) from an entry level (e.g., landing) to a vertically spaced exit level along a shaft. To be proper for this subclass, the elevating apparatus must include:
- a support surface (e.g., elevator car/lift cage) that underlies the load and to which the load is confined during travel,
- rigid or semirigid means for contacting and limiting the travel of the load support surface to back and forth travel along its vertically extending shaft (including inclined ways), and
- drive means (e.g., fluid motors, manually operated cable) for transmitting to the load support surface the force necessary to shift the load between the levels or motion resisting means (e.g., cable linked counterweights) for slowing the travel of the load-supporting surface when moving from a higher load entry level to a lower load exit level.
Conveying apparatus (i.e., an assemblage of elements for moving a load along a predetermined path) for transporting pedestrians (i.e., escalators or moving walkways) from an entrance location to at least one horizontally spaced egress location. To be proper for this subclass, the conveying apparatus must:
- include an underlying surface, or a series of interlinked underlying surfaces, that is intended to normally support and carry individuals to their egress location,
- be arranged or constructed either with a structure that specially adapts the conveying apparatus to the transporting of people or to facilitate potential alternative traversal of the surface(s) by the individuals carried thereon utilizing their standard mode of locomotion (e.g., stepping, walking, manually powering their wheelchair) whenever the underlying surface is idle or the pedestrian wishes to supplement their pace of travel over the underlying surface,
- include rigid or semirigid means for limiting the travel of the supporting surface to a fixed extending path along which individuals are carried when travelling between the horizontally spaced locations, and
- include drive means (e.g., endless chain) for transmitting to the underlying surface the force necessary to shift people between the horizontally spaced locations.
Components of the elevating or conveying apparatus when:
- no specific place for the components exists in another subclass and
- the components are limited to use with the above types of apparatus by a structural modification (e.g., escalator handrails or guards).
Ancillary devices (e.g., elevator call registration systems) for either the elevating or conveying apparatus which are:
- used exclusively with elevating or conveying apparatus and
- have their operations influencing or being influenced by the operation of the elevating or conveying apparatus.
Explanatory Notes or Graphics
(1) Note. Examples of special adaptations for escalators or moving walkways that facilitate the transport of pedestrians are:
- moving steps,
- conveyors combined with handrails,
- conveyors having serrated foot engaging surfaces,
- entrance or exit comb plates,
- passenger operated control of drive means, or
- special layouts facilitating walking along conveying apparatus' path.
(2) Note. Elevating or conveying apparatus otherwise proper for the definition which is either specially modified for use with, or combined with, apparatus for doing work on or treating (e.g., machine tools, furnaces) the discrete loads being carried (e.g., tools shaping load during elevation) are covered in appropriate subclasses for this subject matter.
(3) Note. The load support surfaces of elevators or lifts are intended to support their loads only for a short period of time during handling. Surfaces intended to either support an article in a non-use storage location, support a useable machine or tool, or move one portion of a machine or article relative to another portion thereof are covered in appropriate subclasses for this subject matter.
(4) Note. The discrete load transported by the elevating apparatus of this subclass is either
- a human,
- an animal or other living creature,
- an article,
- unitized bulk material (e.g., cotton bail, ice block), or
- a group or mix of the above types of loads that is moved as a unit between levels.
