Definitions

• the invention relates to a drive device for a movable furniture part, comprising two, arranged on opposite sides of the movable furniture part ejecting devices for ejecting the movable furniture part from a closed position to an open position, wherein the ejection devices each have a spring-loaded locking element for locking the ejection device in a locking position, a guideway with an angled end portion, wherein the locking element is locked in the angled end portion in the locking position, and a separate locking element unlocking element by which the locking element is releasable in overpressure of the movable furniture part in a behind the closed position Letdrückwolfwolf from the angled end portion.
• the invention relates to a piece of furniture with such a drive device.
• Such a drive device is apparent from DE 10 2010 061 482 A1. This is mainly about the opening and closing operation of a movable furniture part, wherein the locking of the ejection device takes place in an angled end portion of a guideway.
• a disadvantage of this known opening and closing device or drive device is that, especially when used in wide drawers by unilateral release or overpressure of the drawer an inclination and a one-sided unlocking can occur. This can lead to an undesirable jamming of the drawer in the furniture body.
• An object of the present invention is therefore to avoid these problems. Therefore, the present invention also relates to a synchronization device.
• WO 2009/1 14884 A2 Another lockable ejection device with a synchronization unit is disclosed in WO 2009/1 14884 A2.
• the unlocking is performed by a relative movement of these two components to each other during overpressing, after which relax an ejection force storage and eject the movable furniture part in the opening direction.
• the locking takes place via a heart-shaped cam track, wherein a latching element mounted on a movable carriage engages in the heart-shaped cam track.
• the unlocking is done by a relative movement of the latching element to the heart-shaped slide track.
• the synchronization takes place by a movement coupling of the linearly movable slides.
• the object is - to prevent an inclination of the drawer in a drive device according to DE 10 2010 061 482 A1 - but solved in that the unlocking of the two ejection devices can be synchronized with the synchronization device.
• each ejection device has a housing.
• the guideways are each formed in the housing.
• the guideways each have an ejection section in addition to the angled end section.
• the unlocking elements can be linearly movable. Particularly preferably, however, it is provided that the unlocking elements are each movable, preferably pivotally mounted on the housing.
• a synchronization of the unlocking can be done for example via a rotatable synchronization rod z.
• two bearing points are formed on each unlocking element and are rotatably mounted on these bearings synchronization rods of the synchronization device.
• these synchronization rods are arranged crossed, so that a rotational movement of the one unlocking element is converted into an opposite rotational movement of the other unlocking element.
• the locking elements are each mounted so as to be displaceable in the guideway via two peg-shaped extensions.
• the drive device can only consist of the two ejection devices and the synchronization device. But for even more diverse uses is preferably additionally provided a retraction device for, preferably damped, pulling the movable furniture part from an open position into the closed position.
• the drive device may be associated with the furniture body.
• the two drive devices are on opposite sides of the movable furniture part z. B. attached directly to the furniture body or on a carcass rail of a pullout guide.
• the drive device is arranged on the underside of the movable furniture part, wherein each ejection device can be coupled via an ejection slide in sections with a body-fixed driver.
• the drive device abuts, so to speak, even on these corpus fixed drivers.
• the retractor may be integrated into the pull-out guide.
