DEFINITION

Classification: 248/560

RESILIENT SUPPORT:

(under the class definition) Structure comprising a resilient means wherein said means takes at least part of the weight of the supported article and permits relative movement or vibration thereof with respect to a support.

(1) Note. Almost every material possesses some elasticity or resilience. Moreover, many substances such as rubber, cork, etc., which are often used in certain applications because of their resilient properties, are also used in other applications because of other properties which they possess, which are unrelated to their resilient properties. Hence, a structure such as a mere mat, pad, sleeve, bushing, cover, etc., which is used primarily because of its frictional, nonmarring or protective properties, is not placed in this subclass, but is classified in the subclasses below on its physical characteristics even though it may incidentally function to dampen sound or to provide a slight cushioning effect.

(2) Note. This subclass does not include a device wherein a resilient means acts in opposition to gravity but without sufficient force to actually support the article, for example, a counterbalanced support which bottoms, or in which the resilient means is ineffective in the normal operation of

the device. Such devices are in the subclasses below. However, this subclass does include a device wherein the resilient article is displaced from a neutral or equilibrium position if the weight of the supported article is taken by the resilient means during such displacement.

SEE OR SEARCH THIS CLASS, SUBCLASS:

556, and 557, for a resilient mounting associated with an aircraft engine support.

638, for a machinery support comprising a vibration dampening or isolating means, which means does not take the weight of the machine.

SEE OR SEARCH CLASS 62, Refrigeration,

295, for a refrigerator comprising a resiliently supported power or heat rejecting element.

267, Spring Devices, particularly

136+, for a spring, per se. The line between Class 248 and Class 267 is as follows: Class 267 will take a spring, per se, even though disclosed as having a supporting function, with or without means for attaching same to the structure with which it is used. Class 248 will take a supporting structure wherein a spring is included as an element of the combination and for which there is no provision in Class 267.

297, Chairs and Seats, appropriate subclasses for a load supporting device wherein the surface itself includes resilient means together with a disclosure of body supporting functions.A nonresilient support surface with resilient under structure is considered a stool or stand of general utility of this class (248).
