Abstract: A rail system includes a first rail unit with a hook portion forming a recessed cavity with an opening. A resilient strip or cord is located within the recessed cavity and is at least partially exposed through the opening. A cam portion positioned apart from the hook portion has a detent and a recessed portion. A second rail unit, releasably fastenable to the first rail unit, has a first flange section insertable into the hook portion of the first rail unit to compress the strip or cord and a second flange section snappable into the recessed portion of the cam portion of the first rail unit. The first flange extends through the opening of the recessed cavity and an end surface of the first flange engages the strip or cord when the second rail unit is fastened to the first rail unit.

Abstract: A rail system of a plurality of rail units is disclosed with a fast, easy-to-use and secure fastening apparatus. The rail system is scalable from toy applications to heavy duty industrial applications by changing the sizes and the materials comprising the components of the system. The fastening apparatus provides high holding forces relative to the ease of snapping to create or release a connection between objects.

Abstract: A fastening or mounting apparatus for releasably joining two objects is disclosed. The apparatus uses a cam portion opposite a hook portion in a structure of one of the objects to engage with flanges, protrusions or ends of the other object. In the case of flanges, one of the flanges deforms a resilient element in the hook portion during insertion, and the other flange snaps into the detent of the cam portion upon application of force. The apparatus may be adaptable from small scale applications to large-scale heavy duty applications.

Abstract: A fastening or mounting apparatus for releasably joining two objects is disclosed. The apparatus has a first component and a second component. The first component may include a plate, two side walls and two flanges extending from the side walls. The second component may include a plate, a first lip and a second lip. The first lip has a cavity holding a resilient element. The second lip may have a convex portion and at least partially define a detent. One of the flanges engages with the resilient element in the cavity while the two components are non-parallel. The first flange compresses the resilient element while the second flange contacts the convex portion. The resilient element biases the second flange against the detent once the two components are parallel.
