Abstract: A method and apparatus for easily and inexpensively coupling a chassis to a slide. Computer related components are disposed within a chassis that is disposed within a rack. A sliding assembly that includes an inner slide allows the chassis to be extended from the rack such that the computer related component can be easily replaced or serviced. The inner slide has an opening extending therethrough that is partially covered by a spring that extends over the opening. A protrusion extends from a side surface of the chassis that can be engaged with the opening so as to couple the chassis to the inner slide. When the protrusion is being inserted into the opening, the spring deforms so as to allow the protrusion to enter the uncovered portion of the opening. When the protrusion reaches the uncovered portion of the opening the spring automatically moves back into its undeformed shape so as to engage the protrusion.

Abstract: A method and apparatus for easily and inexpensively coupling slides together. A spring that couples to one slide engages an opening in an adjoining slide to latch the two slides together in a fully extended position. The spring includes a protrusion that is angled on one side and that is abruptly raised on the other side. The two slides are easily coupled by engaging angled edges of the two slides and moving the slides together. As the protrusion reaches the opening, the force of the spring causes the protrusion to enter the opening such that the slides are in the latched position. Continued movement causes the angled side of the protrusion to contact the side of the opening and moves the protrusion out of the opening, allowing the second slide to be moved into the unextended position. Thereby slides are easily coupled together without the use of any tools. In addition, the slides are easily uncoupled by deforming the spring and moving the slides lengthwise.
