Retention device

A retention device which interacts biasably with a primary object to hold a secondary object at a predetermined location with respect to the primary object. A retention spring has a humped section and feet at either end for pressably interacting with the primary object and the surface on which it rests. Connected with the retention spring is a retention member for retaining the secondary object thereto in a fixed relationship with respect to the primary object. In operation the retention spring is inserted between the bottom of the primary object, such as a typewriter or microwave oven, and the surface on which the primary object rests, such as a desk or table top. The humped section of the retaining spring is biasably forced into a less humped configuration by the bottom of the primary object and the resting surface thereby biasably holding the retaining spring in relation to the primary object. The secondary object, such as a rack or a paper holder, may now be connected with the retention member and thereby the secondary object will be reliably retained relative to the primary object.
