Integral suspension system

A suspension system for a component of an air conditioning system adapted for mounting the air conditioning system to a support surface, the component being mounted relative to the support surface on spaced apart support rails, the support rails having a Z configuration, comprising:

• spring means having a plurality of coils for absorbing motion occurring between the air conditioning system component and the support surface, the spring means having a first end and a second end and defining a spring axis concentric with the coils of the spring means;
• receptacle means operably coupled to a respective one of said support rails for supporting the first end of the spring means, said receptacle means being formed integral to said one of said support rails and defining a partially enclosed volume adapted for receiving and laterally supporting the first end of the spring means the receptacle means comprising four side surfaces and an enclosed top surface, one side surface and the top surface being formed by portions of the Z configured rail and a second side surface being adapted for ready removal;
• and
• base means operably coupled to said support structure for supporting the second end of the spring means, said base means including a plurality of lateral movement restraining means for restraining movement of the second end of the spring means in a direction transverse to said spring axis.

A suspension system for the fan unit of an air handler comprising:

• an air handler having an air handler frame;
• a fan having a fan frame, the fan frame including a Z rail, the Z rail including a first vertical portion interconnecting first and second horizontal portions where the horizontal portions are on opposite sides of the vertical portion so as to form a generally Z shape;
• a spring;
• a spring receptacle enclosing the spring, wherein the spring receptacle includes first, second and third sides arranged about the spring and wherein the spring receptacle is affixed to an end of the Z rail such that the first horizontal portion and the vertical portion of the Z rail together with the spring assembly form an enclosure about the spring;
• the spring having first and second ends such that the first end engages the air handler frame and the second end engages the first horizontal portion of the Z rail of the fan frame.
