Abstract

A device for moving a movable furniture part, including a force accumulator such that by way of the fitted device the furniture part under action of the force accumulator is capable of being put in the opening direction of the furniture part, wherein in a tensioned position of the force accumulator the force accumulator is charged for the opening movement of the furniture part. The device has a locking assembly having a displaceable locking member for locking the tensioned position of the force accumulator, wherein the locking member in the tensioned position assumes a locking position which is unlockable. The locking member in the case of an unlocking procedure is movable from the locking position in a releasing direction, wherein a transmission installation by way of which a movement of the locking member is transmittable to a functional unit which is spaced apart from the locking member is provided.

First claim

The invention claimed is:

1. An opening device attachable to a movable furniture part; the opening device being adapted to assist movement of the movable furniture part in an opening direction and in a closing direction which is counter to the opening direction, the opening device comprising:
a force accumulator configured to push the movable furniture part in the opening direction during an opening movement, the force accumulator having a tensioned position at which the force accumulator is charged for the opening movement of the movable furniture part;
a locking assembly having a displaceable locking member for locking the tensioned position of the force accumulator, wherein the locking member in the tensioned position of the force accumulator assumes a locking position which is unlockable, and wherein the locking member is movable from the locking position in a releasing direction during an unlocking procedure, the locking assembly comprising a movable drive portion, the movable drive portion being mutually adapted with the locking member such that the locking member, upon movement from the locking position under influence of the movable drive portion, is movable onward in the releasing direction;
a transmission installation adapted to transmit a movement of the locking member to a functional unit which is spaced apart from the locking member, the transmission installation comprising a synchronizer bar, the synchronizer bar comprising:
a basic body;
an outwardly projecting engagement portion molded on the basic body in a region of an external contour thereof, the engagement portion configured to engage with a receptacle portion on the locking member; and

first and second convexly-shaped protrusions provided on an outside of the basic body of the synchronizer bar, the first and second convexly-shaped protrusions being diametrically opposed and defining first and second respective bulges extending along and substantially parallel with a longitudinal axis of the basic body across substantially an entire length of the basic body;
wherein in an attached state of the synchronizer bar during movement of the locking member in the releasing direction during the unlocking procedure, a transmission of movement from the locking member to the synchronizer bar is performed by the engagement portion.

2. The device according to claim 1 , wherein the tensioned position of the force accumulator is unlockable by way of a linear repositioning movement of an actuator element of the device, which interacts with the locking member in an actuation direction of the actuator element;
wherein the linear repositioning movement of the actuator element in the releasing direction in relation to a fitted state of the opening device is configured to be performed by way of a movement of the movable furniture part from a predefined closing state of a furniture part on a basic furniture structure in the closing direction, wherein the coupling in terms of motion of the locking member to the functional unit is configured to be performed during the movement of the furniture part in the closing direction.

3. The device according to claim 1 , wherein the drive portion in the locking position of the locking member is contiguous to the locking member.

4. The device according to claim 1 , wherein the drive portion is configured on a movable lever which is coupled to the force accumulator.

5. The device according to claim 1 , wherein the locking member is pivotably mounted, wherein the releasing movement comprises a pivoting movement of the locking member.

6. The device according to claim 1 , wherein in the attached state the longitudinal axis of the synchronizer bar coincides with a pivot axis of the locking member.

7. An item of furniture having a basic furniture structure and a movable furniture part which by way of guide means in relation to the basic furniture structure is movable in an opening direction of the furniture part and in a closing direction which is counter to the opening direction, wherein an opening device according to claim 1 is provided.

8. The item of furniture according to claim 7 , further comprising a functional unit which is spaced apart from the opening device, wherein a first end portion of the synchronizer bar is connected to the locking member of the opening device, and a second end portion of the synchronizer bar is connected to an element of the functional unit.

9. An opening device for moving a movable furniture part in an opening direction in relation to a basic furniture structure of an item of furniture, wherein the opening device comprises:
a force accumulator, the movable furniture part is capable of being put in the opening direction under action of the force accumulator, wherein in a tensioned position of the force accumulator, the force accumulator is charged for an opening movement of the movable furniture part;
a locking assembly having a displaceable locking member for locking the tensioned position of the force accumulator, wherein the locking member in the tensioned position assumes a locking position which is unlockable, wherein the locking member in the case of an unlocking procedure is movable from the locking position in a releasing direction; and
a transmission installation by way of which a movement of the locking member is transmitted to a functional unit which is spaced apart from the locking member, the transmission installation comprising an elongate synchronizer bar or coupling motion of the locking member to the functional unit, a first end portion of the synchronizer bar is coupled to the locking member of the device, and a second end portion of the synchronizer bar is coupled to an element of the functional unit, the synchronizer bar having an outwardly projecting engagement portion molded thereon, the engagement portion configured to interact with a receptacle portion on the locking member, wherein in an attached state of the synchronizer bar during a releasing movement of the locking member in the releasing direction, a transmission of movement from the locking member to the synchronizer bar is performed by way of the engagement portion, the synchronizer bar further comprising first and second convexly-shaped protrusions provided on an outside of a basic body of the synchronizer bar, the first and second protrusions being diametrically opposed and defining first and second respective bulges extending along and substantially parallel with a longitudinal axis of the basic body across substantially an entire length thereof.
