B60T - Definition fr

Definition statement

This subclass covers:

Arrangement of braking elements on vehicles (as defined in the Glossary of terms below).

Portable devices for preventing unwanted movement of vehicles, and especially where the devices are specially adapted to engage an exterior portion of a stationary vehicle to prevent or restrain its movement, e.g. chocks.

Vehicle modifications to facilitate cooling of brakes.

Control systems or parts thereof, in general or specially adapted for vehicles, for processing variables which influence the extent or duration of a braking event, for the following purposes:

Component parts, details or accessories of brake control systems, for example:

Relationship between large subject matter areas

B61H covers brakes or other retarding apparatus peculiar to rail vehicles, and arrangement or disposition of brakes or other retarding apparatus in rail vehicles, but the following aspects thereof in relation to rail vehicles are covered in B60T:

References relevant to classification in this subclass

This subclass does not cover:

Brakes or other retarding apparatus peculiar to rail vehicles; Arrangement or disposition of brakes or other retarding apparatus in rail vehicles (see above)

B61H

Electrodynamic brake systems and control thereof for vehicles, and in general

B60L

Conjoint control of brakes and other drive units of vehicles, such as engine, gearing or clutch (this may be particularly significant when traction control systems operating on more than just brakes are being classified)

B60W

Arrangement of braking elements on cycles

B62L

Arrangement of braking elements on aircraft

B64C 25/42

Dynamo-electric brakes

H02K 49/00

G10L

Informative references

Attention is drawn to the following places, which may be of interest for search:

Brakes themselves, i.e. the devices where the braking effect actually occurs, and actuators directly acting on those devices

F16D

Railway stops, track brakes or retarding apparatus, fixed to permanent way

B61K 7/00

Safety arrangements on roads for slowing, redirecting or stopping errant vehicles, e.g. guard posts, bollards

E01F 15/00

Special rules of classification

In group B60T 8/00, when the subject matter to be classified is characterised by both electronic and non-electronic aspects, it should be classified both in group B60T 8/17 or its subgroups, and in group B60T 8/18.

Glossary of terms

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

Boosters

Means for providing power assistance to the braking effort

Vehicle

This term can have two different meanings here, viz.

(1) 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, which are covered by the relevant subclasses of B61-B64. The term "vehicle" also includes

(i) vehicular characteristics which are common to more than one of the above-listed types, and

(ii) certain characteristics restricted to automobiles, road or cross-country trailers.

(2) In some instances in this definition, the term "vehicle" has been qualified by another word which takes its meaning outside the scope of (1) above (e.g. "rail vehicle"), in which case the word "vehicle" takes its normal dictionary meaning.

The reader can determine from the context whether an occurrence of the word "vehicle" in this definition falls within the meaning stated in (1) or (2).

Synonyms and Keywords

In patent documents the following abbreviations are often used:
