Patent ID: 7452040

Claim:
A guiding rail for a cabinet pull-out part, comprising: a carcass rail, fixable to a cabinet carcass; a running rail, fixable to the cabinet pull-out part; a center rail slidably connecting the carcass rail to the running rail, permitting telescopic movement of the carcass rail, the center rail, and the running rail with respect to one another from a compressed position to an extended position; a blocking device comprising a rod extending longitudinally to the running rail, and being mounted within the running rail to be rotatable about a longitudinal axis, at least one first snap-in tooth projecting from the rod transversely to the longitudinal axis engageable with a first opening in the running rail, a notch lever pivotally disposed at a rearward end of the center rail, at least one second snap-in tooth associated with the notch lever, engageable with a second opening in the carcass rail, and a first spring biasing the at least one second snap-in tooth to engage the second opening in the carcass rail, wherein, when the guiding rail is fully extended, the at least one first snap-in tooth rests against a forward face of the center rail, the first spring acts on the notch lever such that the at least one second snap-in tooth is biased in the direction of the carcass rail, and the at least one second snap-in tooth engages with the second opening in the carcass rail, thereby establishing a blocking action; and an operating lug disposed in a rearward end of the running rail, wherein the operating lug acts upon the notch lever to release the at least one second snap-in tooth, thereby at least partially terminating the blocking action, wherein the guiding rail is lockable both in the extended position and the compressed.
