Description

The present invention relates to a device for opening a relative to a furniture body movable furniture part according to the preamble of claim 1 and 8 and a piece of furniture.

Generic opening devices for furniture parts movable relative to a furniture body, in particular for drawers or swing doors, are known in numerous designs from the prior art. So-called ejection devices are used, especially in handle-free drawers or furniture doors, which cause the drawer is partially opened by slight pressure in the insertion direction to allow intervention in the then existing gap between drawer front or door and the body of the piece of furniture.

A disadvantage of the conventional systems is that the triggering of the ejection device works well only by pressing against the front panel in a central region of the front panel or near the fitting. However, pressing the drawer panel or the furniture door in the outer or edge region of the front panel or the door can cause either the ejector is not triggered or in the case of several arranged in the outer areas of the drawer or the furniture door ejectors that only the Ejector is activated, which is closest to the pressure point. This can lead, for example, by a jamming to the jamming of the drawer in the furniture body.

From the EP 1 314 842 A1 is an opening device with two coupled tripping and drive units with a trigger element and a drive element known, wherein a locking element for releasing a movable furniture part can be unlocked by the action of force on at least one trigger element. Once one of the release lever by inserting the drawer comes with its feeler on a stop of the furniture body to concern, both release levers are slightly pivoted, so that with a pawl coupled release lever and thus the drawer released and thereby the ejection of the drawer is triggered.

When in the EP 1 396 212 A1 revealed opening device, the retraction of a pull-out part in a cabinet element and the extraction of the extract part of the cabinet element by two pivotally mounted pivoting lever is carried out with a control curve.

Object of the present invention is therefore to provide a device for opening a relative to a furniture body movable furniture part, with an alternative operation of the movable furniture part is made possible anywhere and at the same time a deadlock is effectively prevented.

The object is achieved by a device for opening a relative to a furniture body movable furniture part with the features of claims 1 and 8 and by a furniture with the features of claim 10.

In the case of the opening device provided with at least two ejection devices, the at least two ejection devices can be triggered exclusively in the event of a stop of at least two triggering elements coupled to each other in a movement-dependent manner, the triggering elements being connected to the rear wall of the movable furniture part or to a strut attached to the furniture body transversely to the ejection direction Furniture carcass itself axially rotatably mounted rod are connected, wherein the triggering elements in the sense of a two-armed lever are secured against rotation on the rod. This ensures that the movable furniture part can not jam in a misalignment in the furniture body by triggering the ejection device, but that the movable furniture part before the ejection process, if necessary, is aligned and only then the ejector is triggered.

In addition, an alignment of the triggering elements to the contact points of the ejection device / s or the stop / stops before triggering the ejection device (s) is ensured in a mechanically simple manner. If, for example, a point in the vicinity of a side edge of the front panel is selected as the pressure point for opening a drawer, the rear wall of the drawer is first pressed against a first arm of the lever, which evades as long as the drawer is pushed further back, until the second arm of the lever comes into contact with the back of the drawer. In this position, the two-armed lever is fixed in its position, so that the further insertion of the drawer leads to a triggering of the ejector.

Advantageous embodiments of the invention are the subject of the dependent claims.

According to a further embodiment variant, at least two ejection devices are mounted on a front side of the movable furniture part opposite the rear side of the movable furniture part spaced from each other, wherein projecting from the ejector plungers to which the triggering elements can be applied.

Alternatively, the ejection devices are mounted on or in the side frames of the movable furniture part with the plungers of the respective ejection devices protruding beyond the front sides of the side frames opposite to the front side of the movable furniture part.

In an alternative embodiment variant, the two ejection devices are mounted spaced apart on inner side walls of the furniture body.

Also for the triggering elements various embodiments are conceivable. Thus, according to one embodiment variant, the triggering elements are designed as paddles which are plugged onto the end faces of the rod and extend radially in different directions. The paddles form the two arms of the two-armed lever.

Alternatively, the triggering elements are formed together with the rod as pivotable about the rod rocker.

In yet another embodiment variant, the triggering elements are formed as pivotally mounted angular elements at their origin in a plane defined by the direction of movement of the movable furniture member and the longitudinal axis of the rod, which are connected at one end to the rod, the rod being axially is slidably mounted. In this embodiment, the ejection device forms part of the rod, which is in the ejection process extended and so the angle elements simultaneously rotates in the direction of the movable furniture part.

In order to optimally position the trigger elements in different furniture part widths, the rod is formed in the embodiment according to claim 8 adjustable in length.

According to a further alternative embodiment gear wheels are attached to the rod end and the trigger elements are formed as in the gears cross fork elements, each with an attachable to one of the ejection devices end face, wherein the inside of each of the fork legs is formed with a toothing, so that at a Rotation of the rod, the trigger elements are moved in opposite directions.

In the following description of the figures, terms such as top, bottom, left, right, front, back, etc. refer exclusively to the example representation and position of the device and other parts selected in the respective figures. These terms are not intended to be limiting, that is to say, by different working positions or the mirror-symmetrical design or the like, these references may change.

In the FIGS. 1 to 11 a first embodiment of a device according to the invention for opening a relative to a furniture body 1 movable furniture part 2 is shown, wherein the movable furniture part 2 is designed here as a drawer. It is conceivable to use such an opening device even with sliding or pivoting furniture doors or the like.

The drawer 2 is slidably mounted in a known manner via pullout guides 11 in the furniture body 1.

The embodiment of the opening device is, such as in FIG. 1 can be seen, arranged at the back of a drawer 2. The device consists of two ejection devices 6, as in FIGS. 10 and 11 is shown attached in the rear region of a side wall of a furniture body 1. From the ejection devices 6 is in the direction of the movable furniture part. 2 a plunger 12 forth, which is activated as known from the prior art by slight depression and then pushed by spring force from the housing of the ejection device by a certain length and thereby pushes the movable furniture part in the opening direction. The movable furniture part 2 is thereby opened a bit, so that a user can engage behind the front panel 3 of the drawer or even a furniture door (not shown) and fully open.

To trigger the ejection devices 6, two trigger elements 9 are arranged on the rear side of the movable furniture part 2, which are coupled to each other via a rod 8 non-rotatably. The rod 8 is mounted on two bearing blocks 10 preferably in the region of their ends on the back 5 or the front side of the side frames 4 such that the rod is rotatable about its longitudinal axis. The trigger elements 9 are attached to the ends of the rod 8 at an angle of 180 ° and formed here as radially extending in different directions away from the rod in the direction of the back of the furniture part 2 extending paddle. By the rod 8, the trigger elements 9 are coupled in the sense of a two-armed lever smoothly motion-dependent. Due to the power coupling that takes place, gravity has no influence on the system under consideration, as the one-sided system does not trigger the ejection process.

Such as in FIG. 5a As shown, the ejectors 6 are mounted at different heights on the furniture body. This ensures that the triggering elements 9 are pressed so far from the ejector 6 backwards, ie here in the direction of the back of the drawer 2, with only one-sided stop with one of the ejectors 6, without being triggered until the second trigger element 9 with the second ejector 6 comes into abutment and only then by further pushing the drawer in the direction of the ejection elements 6, a simultaneous release of the ejectors 6 is effected.

The course of such opening operation is in the FIGS. 5 to 9 vividly illustrated. It is in FIG. 5 a state shown in which the drawer 2 is in its closed position. In FIG. 6 The drawer is easily inserted into the furniture body. In this case, a first trigger element 9 touches one of the ejection devices. In the FIGS. 7a and 7b is the drawer 2 still pushed a little further into the furniture body 1. This is accompanied by a pivoting of the arranged on the rod 8 trigger elements 9 such that now both trigger elements 9 with the two ejectors 6 are in the field. FIG. 8 shows the drawer in a position in which the drawer is pushed into the furniture body 1 so far that the ejectors 6 are triggered. This can be seen from the fact that the plunger 12 of the ejector are completely pressed into the housing of the ejectors. FIG. 9 then shows a pushed out of the furniture body 1 by a certain distance drawer 2, wherein during the ejection both plunger 12 of the ejector 6 are in contact with the attached to the back of the drawer 2 trigger elements.

The FIGS. 10 and 11 Finally, show the further extended state of the drawer from the furniture body 1 with the ejectors 6 maximum ejected tappets 12. The plunger 12 are, as known from the prior art, pressed only when closing the drawer by the contact with the trigger elements 9 again.

A further embodiment of the opening device is in the FIGS. 12 to 20 shown. The ejection devices are embedded in the side frames 4 of the drawer 2, wherein the plunger 12 of the ejection device 6 protrude from a rear end side of the side frames 4. It is also conceivable for a particularly shallow depth of the furniture that the trigger elements can also dip into the side frames to reach the plunger 12.

The arranged on the rod 8 triggering elements 9 are mounted here on a arranged in the rear region of the furniture body cross member 13 in the bearing blocks 10. With a corresponding design of the bearing blocks 10, the rod 8 could be stored with the bearing blocks 10 directly to the rear wall of the furniture body 1 or on the carcass side walls.

The triggering elements 9 are also coupled to each other in terms of movement in the sense of a two-armed lever. Accordingly, the ejectors 6 are embedded in the side frames 4 of the drawer 2 at different heights in the side frame.

The analogous to the above embodiment, movement sequence of an opening operation is for this embodiment in the FIGS. 16 to 20 shown.

Yet another embodiment variant of the opening device is in the FIGS. 21 to 27 shown. Here the ejector is floating. The opening device 14 here consists of an ejection device 20 from which a rod 21 projects from one side. The rod 21 and the ejection device 20 are coupled at the opposite ends with respective trigger elements 18. The trigger elements 18 are rotatably mounted on a transverse strut 23 each on a pin 19. The triggering elements 18 are here designed as circular sectors, which are mounted in their origin on the pin 19. At one leg end of the two angle pieces, the ejection device 20 and the protruding from the ejection device 20 rod 21 are articulated via a coupling member 22 and at the end of the other leg of the trigger elements 18 each mounted in a housing 15 spring-loaded plunger 16 is coupled. The spring inserted in the housing 15 serves to align the system. The system is brought to the zero position via it.

Now, if the drawer 2 is pressed into the furniture body 1 from the front panel 3 ago in the furniture body 1, then the back of the drawer 2, depending on the position at which the user presses against the front panel 3, either simultaneously at both plunger 16 or only to one of the two plungers 16. In the latter case is by the impressions of example in FIG. 23b Upper plunger 16 of the lower plunger 16 is pressed by a motion transmission through the opening device 14 in the direction of the back of the drawer 2, so that only by two-sided stop the plunger 16 of the opening device 14, a triggering of the ejection device 20 can take place. If the ejector 20 is activated, both plungers 16 are pressed simultaneously against the back of the drawer 2 and pushed so the drawer 2 from the furniture body 1 out.

In addition to the embodiments described here is also conceivable that the trigger elements 9 are formed together with the rod 8 as pivotable about the rod 8 rocker or that centrally on the rod 8, a further trigger element is arranged, which is a single ejection device triggers when the mounted on the ends of the rod 8 triggering elements with the rear wall of the furniture body 1 or a stop attached to this stop.

As yet another embodiment, it is conceivable that gears are attached to the rod 8 on one side and the triggering elements are formed as the sprockets cross-fork elements, each with an attachable to one of the ejection devices end face, wherein the inside of each of the fork legs is formed with a toothing. As a result, upon a rotation of the rod 8, the triggering elements are moved in the opposite direction and thus ensure a stop of the triggering elements with both ejection devices before the ejection devices can be triggered.
