Patent ID: 7478967

Claim:
A rail system, comprising: a horizontally extending rail suspended from a mounting surface, wherein the rail is configured to suspend a curtain therefrom, the rail including a first groove, and a second groove configured to receive curtain runners attached to said curtain; at least one safety connection coupled to the rail, the safety connection comprising: at least one first retaining element; and at least one second retaining element; wherein after mounting the rail to the mounting surface, one of the retaining elements is coupled to the rail in the first groove and the other of the retaining elements is connected to the mounting surface, the first and second retaining elements being detachably connected to each other such that, under influence of a tensile force applied to the retaining elements, the first and second retaining elements disconnect from each other, wherein the second retaining element integrally forms a plurality of circumferentially arranged resilient lips, and wherein the first and second retaining elements are configured to cooperate via the integrally formed resilient lips to effect said detachable coupling of the retaining elements, wherein the first retaining element, after mounting the rail to the mounting surface, extends at least partly through a substantially vertical passage of the second retaining element defined by the resilient lips and wherein the plurality of resilient lips extend obliquely towards each other to form a constriction of said passage of the second retaining element to retain the first retaining element within said passage in a couple position, and wherein the plurality of resilient lips deform radially outward to detach the first retaining element from said passage and the coupled position.
