Pull-out guide

Abstract

A pull-out guide for movably mounting a first furniture part on a second furniture part, includes a first rail to be connected to the first furniture part; and a second rail to be connected to the second furniture part. The two rails are movably mounted relative to each other, and a closing device has an electrically operable adjusting element. The adjusting element blocks a relative movement of the two rails in a closed position and permits the relative movement in a release position. A spring device biases the adjusting element into the closed position, and the adjusting element can be displaced into the release position by one of the two rails or an actuator connected thereto counter to the force exerted by the spring device during a movement in a first direction relative to the other rail.
