Abstract
The invention relates to a movement device for drawers, including an extending mechanism. A blocking element can be moved from a retracted position into an open position or a partially open position by the extending mechanism, and the extending mechanism is held in the retracted position by an overstroke mechanism. The overstroke mechanism has a switching element which is held on a stop by a blocking element in the retracted position and can be lifted from the stop when an overstroke is applied onto the switching element. An improved switching behavior can be achieved in that the blocking element is offset transversely to the overstroke direction when the overstroke is applied.
Claims15
A movement device for a drawer, comprising:
- a push-to-open slide assembly configured to move from a closed position to a part-open position corresponding to a closed drawer position and a part-open drawer position, respectively, the push-to-open slide assembly including an overstroke mechanism including:
- a switching element including a blocking member;
- wherein the blocking member includes a beveled deflection part;
- a switching module including a stop configured to be engaged by the blocking member in the closed position to hold the switching element against an opening movement of the drawer;
- wherein the switching element and the switching module are configured such that when an overstroke inward motion in an overstroke direction is applied to the drawer the blocking member is disengaged from the stop in a first switching movement and during the overstroke inward motion the blocking member is offset in a sideways direction transversely to the overstroke direction and transversely to a vertical plane parallel to the overstroke direction;
- wherein the switching module includes a shoulder adjacent the stop, the shoulder being separated from the stop by a step, the shoulder being configured to receive the blocking member when the blocking member is offset in the sideways direction when the blocking member runs over the step during the overstroke inward motion;
- and wherein the switching module further includes an opening deflection bevel and a return region, the opening deflection bevel being configured to be engaged by the beveled deflection part to deflect the blocking member vertically transversely to the overstroke direction into the return region during the overstroke inward motion.
A method of moving a drawer from a closed position into an open or part-open position, comprising:
- (a) holding the drawer in a closed position with a blocking member of a switching element abutting against a stop of a switching module;
- and
- (b) applying an overstroke movement in an overstroke direction to the drawer and thereby:
- during the overstroke movement, lifting the switching element from the stop;
- during the overstroke movement, moving the switching element over a step separating the stop from a recessed shoulder;
- during the overstroke movement, offsetting the blocking member into the recessed shoulder in a sideways direction transversely to the overstroke direction and transversely to a vertical plane parallel to the overstroke direction when the switching element moves over the step;
- and wherein the offsetting further includes engaging a beveled deflection part of the blocking member with an opening deflection bevel of the switching module to deflect the blocking member vertically transversely to the overstroke direction into a return region of the switching module during the overstroke movement.
