EJECTION DEVICE FOR A MOVABLE FURNITURE PART

Abstract

An ejection device includes a support formed as a housing; an ejection element for ejecting the movable furniture part from a closed position into an open position along an ejection path; an ejection force accumulator which applies a force to the ejection element in the opening direction of the movable furniture part; and a clamping device for clamping the ejection force accumulator. The clamping device has a clamping element to be coupled to the movable furniture part, and a movement transmission element, in particular a rotatable movement transmission element, between the clamping element and the ejection element. The clamping element and the ejection element can be moved in opposite directions when coupled by the movement transmission element when the ejection force accumulator is clamped, and the ejection element, the movement transmission element, and the clamping element are moveable together relative to the support over a first part of the ejection path.

10. The ejection device according to claim 9, wherein the retrieving element comprises a slider and the movement transmission element formed as a gear wheel and being rotatably supported in the slider.

11. The ejection device according to claim 8, wherein the retrieving element is displaceably supported in a limited manner in the guide track comprising two end abutments and formed in the carrier.

12. The ejection device according to claim 1, wherein the ejection force storage member can be tensioned by the tensioning device when pulling the movable furniture part in the opening direction, preferably along a tensioning path following the ejection path.

13. The ejection device according to claim 1, characterized by wherein a locking device for locking the ejection element in a locking position, wherein the locking device can be unlocked by over-pressing the movable furniture part into an over-pressed position located behind the closed position.

14. The ejection device according to claim 13, wherein the locking device comprises a, preferably cardioid-shaped, sliding guide track formed in the carrier, a control lever movably, preferably rotatably, supported on the ejection element and a control pin arranged on the control lever and engaging the sliding guide track.

15. An item of furniture, comprising a furniture carcass, a movable furniture part and an ejection device according to claim 1 for the movable furniture part.

16. The item of furniture according to claim 15, wherein the movable furniture part is formed as a furniture door, wherein the furniture door is pivotally supported on the furniture carcass by means of two hinges and the ejection device is arranged on a position distanced to the hinges.

17. The item of furniture according to claim 16, wherein the ejection device is arranged in a region of the furniture carcass opposite to the hinges.

Description

[0013] Further details and advantages of the present invention are described more fully hereinafter by means of the specific description with reference to the embodiments illustrated in the drawings, in which:

[0014] FIG. 1a shows a perspective view of an item of furniture with a furniture door and an ejection device,

[0015] FIG. 1b shows a perspective view of an item of furniture with three drawers and an ejection device each,

[0016] FIG. 2 shows this ejection device in an exploded view,

[0017] FIG. 3 shows a perspective view of the assembled ejection device,

[0018] FIGS. 4 to 12 show in a top view the movement sequence of the ejection device during the ejection, tensioning and retrieving and

[0019] FIG. 13 shows in an overview the movement sequence of the ejection device on one side.

[0020] FIG. 1a shows an item of furniture 21 with a furniture carcass 22 and a movable furniture part 2 in the form of a furniture door. The movable furniture part is pivotally supported on the furniture carcass 22 by means of two hinges 23. A retracting device (not shown) for the movable furniture part 2 can be integrated in one of these hinges 23. An ejection device 1 is arranged on the furniture carcass 22 on a position remote from the hinges 23. In this case it can be seen that the ejection device 1 comprises a coupling piece 25 on an end facing towards the movable furniture part 2. This coupling piece 25 can be coupled with a coupling counter piece 24 arranged on the movable furniture part 2. In this FIG. 1a the movable furniture part 2 is an open position OS.
