Abstract

The invention relates to a drawer extraction guide with a corpus rail, a drawer rail, and a center rail and carriages arranged between them. It is provided that a synchronization device comprises at least a first and a second gear set with one or more synchronization wheels that are coupled with each other; that rolls a first synchronization wheel of the first gear set on one of the rails, on a component attached to the rail, on one of the carriages, or on an element attached to the carriage; that rolls a synchronization wheel of the second gear set on a further rail, on an element attached to a further rail, on a further carriage, or on an element attached to a further carriage; the synchronization device comprising a transfer member that is linearly and freely adjustable relative to the corpus rail, the center rail, the drawer rail, and the gear sets; and that one synchronization wheel of the first and the second gear set each roll on the transfer member. The invention allows for a compact configuration of a drawer extraction guide that is synchronized in its movement.

Dependent claims

A drawer extraction guide for supporting a drawer to be linearly movable along an extraction direction relative to a furniture body, the drawer extraction guide comprising:

a body rail configured to be attached to the furniture body;
a drawer rail configured to be attached to the drawer;
a center rail configured to be linearly movable and to transmit force between the body rail and the drawer rail;
at least one load-transmitting inner carriage arranged between the body rail and the center rail;
at least one load-transmitting outer carriage arranged between the center rail and the drawer rail;
and
a synchronization device configured to synchronize a movement of the center rail with a movement of the drawer rail, the synchronization device including:
a first wheel set including at least one synchronization wheel, wherein a synchronization wheel of the first wheel set rolls on one of the rails, or on a component attached to one of the rails, or on one of the carriages, or on a component attached to one of the carriages;
a second wheel set coupled to the first wheel set, the second wheel set including at least synchronization wheel, wherein a synchronization wheel of the second wheel set rolls on a further one of the rails, or on a component attached to the further one of the rails, or on a further one of the carriages, or on a component attached to the further one of the carriages;
a transfer member linearly movable with respect to the body rail, the center rail, the drawer rail, and the first and second wheel sets;
and
wherein a synchronization wheel of each of the first and second wheel sets rolls on the transfer member.
