Title: Rack assembly that does not require tools for coupling slides together
Inventor: KAMINSKI JOSEPH W
IPC: A47B88/49
Filed: 2002-10-18
Granted: 2005-08-11
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. Thereby the slides are easily detached without the use of any tools.
