Description

The The present invention relates to an ejection lever for an ejector for expel a movable furniture part from a closed end position in or on a furniture body, with an elongated one Lever body.

Ejection lever after The prior art are always in terms of the length of its lever body for a furniture body or for a drawer with a certain width optimally suitable. Besides is a given ejection lever if applicable in conjunction with a furniture carcass or a drawer, whose width differs only insignificantly from the optimal width.

Becomes For example, a specific ejection lever for a too narrow drawer used, so drives the ejection lever while the opening movement over the Rear panel support the drawer and creates so unpleasant noises. Furthermore, it is in itself known, by choosing a predetermined shape and length of the lever body the force curve during of ejection set. Shape and length of the lever body are tuned to a certain width of the drawer.

task The invention is to develop a generic ejection lever such that he is universally applicable.

These Task is by an ejection lever solved with the features of claim 1.

By the length variability of the lever body is one and the same ejector lever for different wide drawers or used in different width furniture carcasses.

Especially many design options for the Längenveränderlichkeit of the lever body arise, since it is provided that the lever body along its longitudinal extent consists of at least two sections. Constructively simple is the chosen one Measure, the sections are detachable to connect with each other. therefor For example, a snap connection may be provided. This allows the tool-free attachment or removal of the second Section on the first section.

Further advantageous embodiments The inventions are in the dependent claims Are defined.

at Carcase widths larger than a predetermined width (for example, 300 mm) may be the second section remain on the first section (as-delivered condition). With carcase widths under the given width, the second section can be tool-free from first section to be removed.

To the Driving the ejection lever can be provided that the elongated lever body a coupling member for coupling with an output of a drive unit having.

Around one possible steady course of exertion of force the ejection lever on the movable furniture part while of ejection can be provided that the curvature of the Sections are adapted to each other so that the transition from one of the sections to the other of the sections in that one Area that comes to rest on the movable furniture part, smooth.

Under a smooth transition This is a course of coming to rest on the movable furniture part area understood without kinks. This action becomes a sudden change the on the movable furniture part applied force avoided.

protection is also desired for an ejector for ejection a movable furniture part a closed end position in or on a furniture body with a discharge lever of aforementioned type.

at such an ejector It is preferably provided that the ejection lever by an electric motor is driven.

A particularly comfortable operation arises when the ejector has a touch-latch functionality. This means that the ejector (more precisely, its electric motor) by pulling or applying pressure on movable furniture part triggered can be. This can be done, for example, such that the ejector Having a sensor which is triggered by the ejection lever and when triggered the Electric motor activated. Does it come to a tensile or pressure exertion the movable furniture part, this is how it translates on the with the movable furniture part (for example, on the back) in contact ejection lever, which in turn triggers the sensor.

protection is also desired for a piece of furniture a furniture body and one in or on the furniture body movably mounted furniture part, especially furniture drawer or furniture door, with an ejector of the aforementioned type.

If an ejector with the above-described touch-latch functionality is used in such furniture, of course, provided be to store the movable furniture part in the closed end position in the furniture body so that a gap between the movable furniture part and the furniture body is present. Otherwise, it would not be possible to trigger the ejector by pressing the furniture part into the furniture carcass.

The Width of the gap can be achieved by arranging spring buffers between the movable furniture part and the furniture body be determined.

Further Advantages and details of the invention will become apparent from the following description of the figures. Showing:

1a to 1f different views of an embodiment of an ejection lever according to the invention,

2a to 2f Detail views of the embodiment according to 1 .

3a and 3b two views of a pusher with an ejection lever after 1 .

4a and 4b the use of the ejection lever after 1 in a narrow furniture body and

5a and 5b the use of the same ejection lever in a wide furniture body.

The 1a to 1f show a discharge lever 1 with an elongated lever body 2 , which in this embodiment consists of two sections 3 . 4 composed. The elongated lever body 2 is with a coupling part 7 connected. The coupling part 7 acts in the arrangement of the ejection lever in an ejector with the output of a drive unit (for example, electric motor) together. The in the 1a and 1c to 1e apparent toothing couples to a rotary potentiometer, which can act as a sensor for triggering the drive unit, especially in the touch-latch functionality.

In the embodiment according to 1 is a snap connection for releasably securing the sections 3 and 4 provided to each other. The training of this snap connection is particularly in 2 seen.

To increase the length of the elongated lever body 2 becomes the second section 4 on the first section 3 postponed. In 2 the deferred state is shown.

By pushing on the front nose comes 12 of the section 4 under the footbridge 13 of the section 3 to lie. The springy hook 14 prevents the section 4 easy from the section 3 can be deducted. If you press the rag 15 at the section 4 down, so will the hook 14 deflected laterally (see in particular 2d ) and the section 4 can from the section 3 be removed.

2e shows like the coupling part 7 about his teeth with the actuator 16 a rotary potentiometer (located in 2e not shown part 9 the ejector 8th ) works together.

2f shows the arrangement of a gear 18 over which the ejection lever 1 in operation by a part not shown 9 the ejector 8th arranged drive unit is driven.

The 3a and 3b show a pusher 8th with a discharge lever 1 according to the embodiment of 1 and 2 , This is just an illustration of how the ejector lever 1 in the ejector 8th is arranged.

The part 9 the ejector 8th has the drive unit (electric motor), the control electronics, sensors and the power supply.

The 4a shows a furniture body 10 with multiple ejectors 8th and a furniture part shown as an example 11 , There are three more furniture parts 11 provided the better visibility of the ejector 8th because of the furniture body 10 were removed.

The 4b shows the operating position of the ejector 8th with the ejector lever having a first small length in this embodiment 1 , In this state, the ejection lever is located 8th on the rear wall of the movable furniture part 11 (not shown here) and can this by pivoting the ejection lever 1 in the direction of the rear wall of the movable furniture part 11 from the closed end position in the furniture body 10 emit.

The 5a shows a wider furniture body with the same ejectors 8th ,

5b shows in detail the arrangement of the same ejector 8th , wherein its ejection lever 1 this time a lever body 2 having greater length. In the case shown was a second section 4 on the first section 3 attached. Not shown, but conceivable, of course, would be the use of differently designed variable-length ejector.
