Description

The present invention relates to an extension device for insertion into a cabinet element of a furniture device, comprising first linear guide means which are fastened in the cabinet element, a pull-out, which is equipped with second linear guide means, which are movable relative to the first linear guide means and to which a holder for a Front cover is attached, which holder is connected via a pivoting mechanism about an axis transverse to the extension direction pivotally connected to the second linear guide means and thus the holder with attached front cover can be swung open and optionally with the pull-out of the cabinet element.

Such Auszugeinrichtungen be used in particular in cabinet elements of kitchens in which, for example, container systems are housed for receiving waste. Here, it is advantageous if the front cover of the extension device, with which this cabinet element is lockable, is pivotable about a horizontal axis mounted in the lower area, with this swing-front cover one or more Kehrrichtbehälter are mounted so that they pivot with the swing-front cover, so that the ejection device does not have to be pulled out of the cabinet element for introducing rubbish into this container. Rather, it is sufficient that the front cover swung open and the rubbish can be thrown into the thus released container. Of course, the extension device with the front cover also take off, so that the accessibility to the entire area of the pull-out is optimally possible.

From the DE-A-4 107 039 Such a slide-out device is known in which the pull-out element can be pulled out of the cabinet element and which is closed by a front cover which can be swung open. To swing the front cover by one to allow horizontal pivot axis, a lever system is provided which has a complicated structure. In addition, it is necessary that, when closed, the front cover is locked to the cabinet member via a locking device which must be unlocked via a correspondingly actuatable triggering mechanism for opening the front cover.

The object of the present invention is therefore to provide a Auszugeinrichtung having a mounted on a holder front cover, which should be swung open in a simple manner and optionally the pull-out with swung-front cover can be pulled out of the cabinet element, the storage of the swivel bracket should be as simple as possible and the operation of this extractor can be done in an optimal manner.

According to the invention, the solution of this object is achieved in that the pivoting mechanism comprises two laterally attached to the bracket tabs, which are articulated pivotably about the axis of the second linear guide means, and that on the holder at least one control cam is fixed, which with the holder to the Axis pivots and retracted in the pivoted position of the holder in attached to the first linear guide means guide means and extends when pivoting the holder from the guide means and a withdrawal of the pull-out with swung-bracket with front cover from the cabinet element permits, and that a locking mechanism is mounted with in which the holder is locked to the front cover in the extended position of the pull-out in the pivoted-up position.

By this configuration, the cabinet element can be opened in a simple manner by the front cover, which is attached to the holder can be swung without additional required handles, during the Aufschwenkvorgangs the pull-out is essentially held, only when fully swung front cover is enabled Pull the pull-out element out of the cabinet element. Here, the holder is locked with the attached front cover in the pivoted position. This achieves a clearly defined sequence of movements, unwanted movements and incorrect manipulations are eliminated.

Advantageously, two control cam elements are arranged on the holder, which are each attached to a lateral region of the holder, whereby a great stability is achieved.

Advantageously, each cam element comprises a first control surface and a second control surface, and the guide means attached to the first linear guide means are formed of a first roller and a second roller, which cooperates first roller with the first control surface and which second roller with the second control surface whereby one achieves a precisely defined sequence of pivotal movement of the holder with the front cover attached thereto in a simple manner.

Advantageously, the respective control cam element is formed as a tongue-shaped extension of the tab, which allows a particularly simple production.

A further advantageous embodiment of the invention is that the locking mechanism is designed as a pivot lever, which can be pressed by means of spring force in the locking position. For this purpose, the pivot lever is pivotally mounted with the one end portion of the first linear guide means, the other pivotable end portion is supported in the locking position on the first control surface and the pivot lever is unlocked upon insertion of the pull-out in the cabinet element by the first roller. This gives a simple structure of the locking mechanism, a trouble-free function is guaranteed.

Advantageously, the swung-out position of the holder is limited by a stop, whereby this swung-out position is clearly defined.

A further advantageous embodiment of the invention is that the pivoting movement of the holder is braked by the swung-out position in the pivoted position via damping means. As a result, a smooth and quiet closing of the extension device is achieved.

Advantageously, one end of a tension spring is attached to the holder, the other end is connected to the second linear guide means. As a result, the holder with the front cover attached thereto is brought into the cabinet element automatically in the fully retracted state of the pull-out element into the cabinet element closing position.

From the Fig. 1 and 2 in each case a spatial representation of the extension device 1 can be seen, which can be used in a cabinet element, as will be described later. This extraction device comprises first linear guide means 2, which are formed from two rails 3 aligned in parallel. These rails 3 are connected to each other via cross struts 4. At the pull-out end region of the rails 3, an upwardly directed web 5 is fastened in each case. At this web 5 each have a support roller 6 is freely rotatably mounted. Placed on these support rollers are the second linear guide means 7, which in turn are formed from two further rails 8, which are also aligned parallel to each other. These further rails 8 form the rolling surface for the respective support roller 6, so that the second linear guide means 7 are displaceable with respect to the first linear guide means 2. At the other rails 8 each have a further web 9 is attached to each of which a guide roller 10 is freely rotatably mounted. The guide rollers 10 are kept out in the rails 3 in a known manner. This allows the pull-out 11 with its second linear guide means 7 along the first linear guide means 2 from an inserted position to an extended position, as shown in the FIGS. 1 and 2 is shown, move in a known manner.

At the extension end portion is a holder 12 for a front cover 13 (FIG. Fig. 3 ) appropriate. This holder 12 consists of a cross bar 14, which is equipped on both sides with a tab 15. The tabs 15 are each pivotally mounted on the further web 9 of the second linear guide means 7, the two tabs 15 and thus the holder 12 are therefore about the axis 33, which is transverse to the withdrawal, with respect to the second linear guide means 7 pivotally.

At the two tabs 15, a control cam element 16 is attached in each case. This cam member 16, which will be described later in detail, is formed as a tongue-shaped extension 17 which is integrally formed on the tab 15. At this a first control surface 18 and a second control surface 19 is mounted, the first control surface 18 cooperates with a first roller 20 which is rotatably mounted on the web 5, while the second control surface cooperates with a second roller 21, which also on the web. 5 the first linear guide means 2 is attached. This will be described later in detail.

In the region of the cam elements 16, a locking mechanism 22 is mounted, in the region of the tab 15 also damping means 23 are arranged, with which the pivoting movement of the holder from the pivoted position is braked in the pivoted position, which will also be described in detail later.

Fig. 3 shows the extension device 1, which is inserted in a cabinet element 24. Here, the first linear guide means 2 are fixed to the bottom 25 of the cabinet element 24 in a known manner. In a known manner, the second linear guide means 7 are displaceable over the support roller 6 and the guide roller 10 with respect to the first linear guide means 2 in the extension direction. On the second linear guide means 7 attachments may be appropriate, such as refuse containers 26 or other common facilities.

On the cross bar 14 of the holder 12, the front cover 13 is fixed, which is usually done by screwing, on the front cover 13, a manual operating element 27 and a foot actuator 28 is attached. An operator can thus the front cover via the manual operating element 27 or via the foot actuator 28 in the in Fig. 3 bring shown swung position. The refuse container 26 could also be arranged so that it pivots with the front cover 13, thereby easily rubbing be introduced into the container by the Front cover 13 is merely swung open without the pull-out element 11 has to be pulled out of the cabinet element 24.

Like from the Fig. 4 and 5 it can be seen, the damping means 23 consist of a damping element 29 which is equipped with a braked shaft and arranged on this braked shaft gear. The gear cooperates with a gear transmission 31 which in turn is engaged with a rack 32. This rack 32 is integrated in the tab 15, and is arranged radially with respect to the axis 33 about which the tab 15 of the holder 12 is pivotable.

Also from the Fig. 4 and 5 the locking mechanism 22 can be seen. This consists of a pivot lever 34, whose one end region pivotally on the further web 9 ( Fig. 1 and Fig. 2 ), the other end portion of this pivot lever 34 is in the locking position as shown in FIGS Fig. 4 and 5 is shown on the first control surface 18 of the cam member 16. The pivot lever 34 is pressed by a spring 35 in the locked position, as in Fig. 4 and Fig. 5 is shown, this locked position of the pivot lever 34 is determined by a stop 36.

How out Fig. 4 can be seen, the swung-out position of the holder 12 and consequently the tab 15 is also determined by a stop 37, which is formed by the guide surface of the other rail 8 of the second linear guide means 7, against which stop 37, a portion of the tab 15 in the locked state Plant comes. The locked position in the swung-out state is thus determined by the pivot lever 34 and this stop 37.

The operation of the device will be described below. Fig. 6 shows the pull-out 11 in the fully inserted into the cabinet element position, the holder 12 and consequently a front cover attached thereto are in the pivoted-down position. The tab 15, which is pivotable about the axis 33, is also correspondingly swung. The pivot lever 34 is held by the first roller 20 against the spring force in the pivoted unlocked position. The first control surface 18 of the tongue-shaped extension 17 of the tab 15 is supported on the first roller 20, the second control surface 19 is supported on the second roller 21 from. By a tension spring 38 shown schematically, one end of which is hinged to the second linear guide means 7, and whose other end is hinged to the tab 15, the tab 15 and thus the holder 12 in the in Fig. 6 drawn shown pivoted position.

When the cabinet element is to be opened, for example, an operator grasps the manual operating means 27 of the front cover 13 (FIG. Fig. 3 ) and pull on it. Due to the design of the control surfaces 18 and 19 and their interaction with the first roller 20 and the second roller 21 is a pure pull-out of the pull-out 11 is not possible, it must therefore simultaneously be made a pivoting movement about the axis 33 of the tab 15 to allow a pull-out like this in Fig. 7 is shown. The first control surface 18 moves along the first roller 20, the second control surface 19 moves along the second roller 21, during a slight extraction movement thus takes place a pivoting movement of the tab 15 and consequently the holder 12 together with a front cover attached thereto. By the extension of the pull-out 11 moves the pivot lever 34 of the locking mechanism 22 away from the first roller 20, by the spring 35 (FIG. Fig. 5 ) pivots this pivot lever 34 in a clockwise direction.

Upon further pivoting, the first control surface 18 and the second control surface 19 extend along the first roller 20 and the second roller 21, respectively Fig. 8 is shown, it then areas of the first control surface 18 and the second control surface 19 are reached, through which the fully swung-out position of the tab 15 and thus the holder 12 is reached, shown in FIG Fig. 8 , The stop 37 abuts the other rail 8. The pivot lever 34 is further released by the first roller 20, it approaches the locking position.

When this fully swung-out position of the tab 15 and thus the holder 12 and the front cover attached thereto is reached, the pull-out element 11 can be pulled out, as shown in FIG Fig. 9 is shown, the first roller 20 releases the first control surface 18, the second roller 21 releases the second control surface 19, the pivot lever 34 reaches the locking position in which it is supported on the first control surface 18. In this and in the further extended position of the pull-out 11 thus the swung-out position of the holder 12 is locked.

When inserting the extended pull-out element 11 with the pivoted-up support 12 and the front cover 13 attached thereto, the sequence of movements described above is passed through in the reverse order. The tongue-shaped extension 17 with the two control surfaces 18 and 19 moves between the first roller 20 and the second roller 21, the first control surface 18 and the second control surface 19 come into contact with the first roller 20 and the second roller 21, the pivot lever 34 is pivoted back by the first roller 20 against the spring force and comes out of engagement with the first control surface 18, upon further insertion of the pull-11 is controlled by the first and second control surface 18 and 19 and the first and second rollers 20 and 21, the controlled Swing in the holder 12 until it reaches the fully closed position as shown in Fig. 6 is shown. By the tension spring 38, when the pivot lever 34 is unlocked, the pivoting of the holder 12 with the front cover 13 mounted thereon can be carried out automatically, wherein the damping means 23 can be braked as far as the pivoting movement that no strong impact occurs.

With this inventive embodiment of a pullout means a simple construction of the pivoting mechanism is achieved, whose movement is optimal, and which can be produced inexpensively.
