Definition statement

This subclass 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:

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:

Components of the elevating or conveying apparatus when:

Ancillary devices (e.g., elevator call registration systems) for either the elevating or conveying apparatus which are:

Explanatory Notes or Graphics

(1) Note. Examples of special adaptations for escalators or moving walkways that facilitate the transport of pedestrians are:

(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, transporting human body during its cremation) 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 nonuse 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

Glossary of terms

In this subclass, the following terms or expressions are used with the meaning indicated:

Cable

a flaccid, elongated, flexible element that can transmit force only when under tension (e.g., rope, wire, chain).

Drive means

means for supplying motive force to an element to be moved which includes both force generating means (e.g., motor) and structural linkage (e.g., gears) needed to transmit the force from the generating means to the element.

Landing

an in situ floor within a structure (e.g., building) (a) that is located adjacent to an elevator shaft or the entrance or egress points of the conveying apparatus' path and (b) to or from which a load (e.g., passenger, cargo, pedestrian) transfers during the charging or discharging of the load-underlying support surface of an elevator or conveying apparatus.

Shaft

a long, narrow, in situ passageway within a structure (e.g., building, ship, mine) which defines the fixed path between the vertically spaced load entrance and exit levels traveled by the load-underlying support surface of an elevator.

Synonyms and Keywords

In patent documents the terms elevator and lift are often used as synonyms.

In patent documents the term dumbwaiter is often used with the meaning of a very small elevator or lift (e.g., normally the support is too small for a person) for moving housekeeping or food items between floors.
