Abstract:
1. Closing and opening device for drawer pull-out guides with a guide rail to be fixed on a carcass wall of a piece of furniture and a running rail which is mounted so as to be displaceable relative to the guide rail and is to be fixed on the drawer, wherein, on a catch housing disposed on one of two aforementioned rails, a movable catch component is provided and is pretensioned by a spring arrangement in a bistable manner into two end positions spaced from one another in a direction of movement of the drawer, and the catch component has a seat for a dog which is provided on the outer rail and moves into the seat during the relative displacement of the rails as a closed position is approached and pivots the pretensioned movable catch component and thereby unlocks it from the associated end position, as a result of which the catch component is moved under the action of the spring tension into the other end position and by way of the dog held in the seat it entrains the rail associated therewith in the direction of retraction of the drawer, wherein the closing and opening device has a touch-latch mechanism that acts on the catch component or acts on or in the catch housing, wherein, when a pushing-in movement in a direction associated with closing the drawer is exerted on the drawer that is retained in the closed position by the closing and opening device, the touch-latch mechanism displaces the catch component and, by way of the dog engaging in the seat of the catch component, the touch-latch mechanism displaces the running rail and the drawer held on the running rail by a predetermined amount in a direction associated with opening the drawer.
