Description

The invention relates to a positioning device for positioning an ejection device for ejecting a movably mounted furniture part from a closed end position relative to a furniture body, with a guide element, which on a substantially horizontally extending cabinet bottom of the furniture body to is fastened, and wherein a carrier element of the ejection device can be positioned by the guide element.

Furthermore, the invention relates to an arrangement with a positioning device of the type to be described and a piece of furniture with such an arrangement. Devices for positioning ejection devices for ejecting movably mounted furniture parts from a furniture body are already known. These devices are used in the assembly of ejection devices, especially in cupboard-shaped furniture with one or more drawers, the drawers are each movable by their associated ejection devices from their closed end positions relative to the furniture body of the furniture in an open position. This can be done, for example, by an ejection element of the ejection device, for example an ejection lever, resting against the rear wall when the end position of the drawer is closed and pressing against this rear wall when activated so that the drawer is ejected from the furniture body in the opening direction. Accurate positioning of the ejection device relative to the drawer is therefore of great importance, since the ejection quality is influenced by the position of the ejection device relative to the drawer. If the ejection lever of the ejection device is too far away from the rear wall of the drawer, the ejection lever can not develop its full ejection effect. If the ejection lever is not centrally applied to the rear wall of the drawer, it can tilt during ejection. If the ejection lever is positioned too close to the back wall, a so-called touch-latch functionality ejector may malfunction as it may eliminate the need for the ejection lever trip path to detect the ejection trigger. Only by an exact positioning of a Discharge device relative to the drawer can be ensured that the aforementioned disadvantages can be avoided and the ejection device can eject the drawer properly. AT 505 970 A1 shows a support structure for at least one ejection device, wherein this support structure comprises a mounting rail and two fastening devices. In one embodiment, a first fastening device is fastened to the carcass base and a second fastening device to the carcass back wall, with an adjustment of the depth position of the ejection device with respect to the movable furniture part by a bearing part of the second fastening device. Although some adjustment in the depth direction of the furniture body may take place, this only takes place in a relatively small area, since the first fastening device is fastened fixedly and immovably to the floor of the carcass. Overall, the assembly work for the support structure of the ejection devices is relatively high, since first the first fastening device on the body floor and then the second fastening device are to be attached to the body rear wall. The mounting rail can then be mounted between these two fastening devices, wherein an adjustment in the depth direction can be carried out by the second fastening device. For a precisely fitting attachment of the mounting rail between the two fastening devices while an increased effort in terms of measuring and attaching the two fastening devices on the furniture body is required.

The invention has therefore set itself the task of providing a comparison with the prior art improved positioning for positioning an ejection device for ejecting a movably mounted furniture part from a closed end position relative to a furniture body. In particular, positioning should take place with the least possible measurement and assembly effort. This object is achieved by the features of claim 1. Advantageous embodiments of the invention are specified in the dependent claims.

According to the invention it is thus provided that the guide element at least one in mounting position at least partially in the depth direction of the cabinet bottom having extending guide for displaceable mounting of the support element. Preferably, the guide can rest in mounting position on the bottom of the cabinet. The ejection device can be arranged, for example, on a carrier element, for example on a mounting bracket. In order to eject a drawer as intended from a furniture body, the ejection device must be arranged in a suitable position relative to the drawer in its closed end position. This is achieved in the proposed positioning by the fact that first the guide element is mounted on the bottom of the cabinet furniture body. The guide element has a - preferably linear - guide, which extends in the mounting position at least partially in the depth direction of the cabinet base (ie in the direction of movement of the drawer), wherein the support element is slidably mounted along this guide. Preferably, the support member during the sliding storage constantly rest on the bottom of the cabinet. This makes it possible to position the arranged on the support member ejection device for drawers with different nominal lengths. For example, the guidance of the carrier element can extend over at least half the depth extent of the cabinet bottom. It is of course also possible to arrange a plurality of ejection devices on the carrier element, so that even drawers with a large load bearing can be reliably ejected.

The carrier element can be fixed after positioning relative to the guide element with the guide element and / or with the cabinet bottom via a fastening device. The fastening device may be, for example, a screw through which the support member screwed onto the cabinet bottom and / or can be screwed to the guide element. But it can also be provided that after the attachment of the support element on the bottom of the cabinet, the guide element can be removed again. As a result, the guide element for the positioning of another ejection device would be reusable.

In a preferred embodiment of the invention it can be provided that the guide element has a longitudinal section and at least one transverse section projecting from the longitudinal section substantially at a right angle, wherein the Longitudinal section has the guide for guiding the support element. It can be provided that the carrier element for displaceable mounting relative to the guide element has at least one groove. Such a groove can for example be designed such that it forms a linear sliding guide, for example a dovetail guide, in operative connection with the guide of the guide element.

The guide element can have a stop, by means of which the guide element can be positioned relative to an edge of the cabinet bottom. The stop can be used to align the guide element flush with the rear edge of the cabinet floor. In a furniture body with a rear wall, however, the stop facilitates the fitting of the guide element in that edge of the cabinet bottom, starting from which the bottom wall attached to the bottom wall, substantially perpendicularly projecting from the bottom of the cabinet in the vertical direction extends. When positioning the ejection device, first the guide element with the stop, which can extend along the transverse section of the guide element, is inserted into the angle, which results from the cabinet bottom and rear wall of the furniture body. If the furniture body has no rear wall, the guide element is placed flush with the rear edge of the cabinet floor. In this case, the stop of the guide element can preferably be formed by a section projecting substantially at right angles from the transverse section of the guide element and extending vertically downwards in the mounting position, through which the guide element can be abutted flush against the edge of the cabinet floor.

It can also be provided that the guide element has at least one recess, through which a mark attached to the bottom of the cabinet is visible. This allows a pre-positioning of the guide element, in particular in the transverse direction of the cabinet bottom. This recess may for example be designed as an opening through which the marking is visible. Thus, the proposed positioning contributes to eliminate possible sources of error in the assembly of ejectors as far as possible. A typical positioning process of an ejector takes place in several steps. First, in a first step, the width of the cabinet bottom is determined and attached at about half the width in the region of the angle between the cabinet bottom and rear wall of the furniture body or in the absence of rear wall in the region of the rear edge of the cabinet floor a mark on the bottom of the cabinet. The guide element is then placed with its stop at the angle between the cabinet bottom and the rear wall of the carcase or in the absence of the rear wall flush with the rear edge of the cabinet floor. In this case, a section protruding substantially vertically downwards in the mounting position from the transverse section of the guide element can facilitate the positioning of the guide element on the trailing edge of the cabinet floor. The guide element is now flush with the rear wall of the furniture body or on the trailing edge of the cabinet base, wherein the guide of the guide element extends at least in sections in the depth direction of the cabinet bottom. The guide element can now be moved along the edge into that position in which the marking attached to the bottom of the cabinet is visible through the recess of the guide element. The guide element is to be fixed in this position, for example by a double-sided adhesive tape, which is attached to the underside of the guide element. In a next step, the support element, on which the ejection device is mounted, is placed on the front end of the guide of the guide element by means of a recess or groove provided for this purpose. Following this, the drawer is pushed in the direction of its closed end position. In this case, the ejection device attached to the carrier element is inserted from the rear wall of the drawer along the guide.

It is particularly advantageous if a spacer is provided, through which a predetermined relative distance between the movable furniture part and the ejection device can be fixed. This spacer ensures that after positioning the ejection device and removing the spacer, a corresponding release stroke for the ejection element of the ejection device is ensured.

By the proposed positioning device, an ejection device, in particular at different nominal lengths of the drawers always to a respective suitable position relative to the rear wall of a drawer associated drawer are brought and mounted, so that the required triggering path to activate the touch-latch function is ensured. Preferably, it can be provided that the spacer is mounted on the ejection device such that the positioning of the spacer on the ejection device, the ejection element, such as an ejection lever, can be locked and thus the spacer also protects against accidental release of the ejection device during positioning - and mounting process offers. The spacer can be arranged, for example, in a corresponding recess of the ejection device.

After the drawer has been pushed into its closed end position relative to the furniture body and the support element has been moved along the guide of the guide element in the depth direction, the drawer is pulled out of the furniture body in a further step. The ejection device or the carrier element, on which the ejection device is mounted, has been correctly positioned by the bearing on the guide of the guide element and by the insertion of the drawer in its closed end position and can subsequently be fastened by means of a fastening device on the bottom of the cabinet. This can e.g. done by a screw connection.

Overall, the proposed positioning device enables ejection devices for movable furniture parts, in particular drawers, to be very easily positioned with a wide range of different nominal lengths and independently of the guide system used, so that they can bring about the ejection process in the desired manner. In this case, a positioning is also independent of the material of the movable furniture part, in particular independent of the material of the rear wall of a drawer such as wood or steel, possible. In addition, with a positioning device according to the invention ejection devices in connection with a variety of furniture carcasses regardless of their construction, in particular regardless of whether in a furniture body, a rear wall is present or not positionable. It can also be provided a cover for the ejection device, which is releasably attachable to the support element. This cover is in mounting position above the ejector and protects the ejector from dripping water. This is particularly favorable if the ejection device is located, for example, in a furniture carcass below a sink.

Protection is also sought for an arrangement with a positioning device according to the invention and an ejection device. The ejection device can have at least one electric drive, by means of which an ejection element of the ejection device for ejecting a movably mounted furniture part from a closed end position can be acted upon relative to a furniture carcass. Of course, however, another type of drive, for example a spring drive, may be provided for acting on the ejection element of the ejection device.

In addition, protection for a furniture with an arrangement of the type described above is sought after.

Protection is also desired for a method according to claim 12.

For ejecting the movably mounted furniture part 3, an ejection device 2, not shown, is provided, which is to be positioned so that the ejection device 2 moves the movably mounted furniture part 3 from a closed end position relative to the furniture body 4 in an open position after activation. For this purpose, the center of the cabinet bottom 6 is first determined approximately in the transverse direction, and a marking M is attached to the bottom of the cabinet 6 in the region of the rear end of the cabinet bottom 6. This can clearly be seen in FIG. 1A, which shows an enlarged section of the region A of FIG. 1. Here, the marking M extends starting from the angle 13, which is formed by the bottom of the cabinet 6 and the rear wall of the furniture body 4 arranged substantially at right angles thereto, in the depth direction T to the front. FIG. 2 shows the furniture body 4 according to FIG. 1 with a guide element 5 arranged on the bottom of the cabinet 6, and FIG. 2A shows an enlarged detail. The guide element 5 is preferably T-shaped and has a longitudinal section 9 and at least one of this longitudinal section 9 substantially perpendicularly projecting transverse section 10. In this case, the longitudinal section 9 constitutes a guide 8 for a carrier element 7 of an ejection device 2 which can be displaceably mounted in the depth direction T (see FIG. 3). The transverse section 0 of the guide element 5 has a stop 12, by means of which the guide element 5 can be laid flush against the angle 13 between the cabinet bottom 6 and the rear wall of the furniture carcass 4.

This is particularly important when the ejector 2 is equipped with a so-called touch-latch functionality. By the spacer 15 can be ensured that after the positioning of the ejection device 2 and after removal of the spacer 15, a defined trip path is provided. 4 shows a drawer 3, which is movable into the furniture body 4 via drawer extension guides 19 in the depth direction T, and FIG. 4A shows an enlarged view of the area A in FIG. 4. For positioning the ejection device 2, the drawer 3 becomes so deep direction T is pushed into the furniture body 4 until the drawer 3 is in its closed end position (Fig. 5). During the insertion of the drawer 3 into the furniture body 4, the rear wall of the drawer 3 strikes the spacer 15. After the closed end position of the drawer 3 is reached, the ejection device 2 has a correct position with respect to the rear wall of the drawer 3, so that the ejection device 2 is positioned after attachment to the furniture body 4 and after removal of the spacer 15 at the intended location. The attachment of the ejection device 2 relative to the furniture body 4 can be effected by a fastening device, for example a screw connection. FIG. 5 and FIG. 5A show the arrangement according to FIG. 4 and FIG. 4A, wherein the drawer 3 has been pushed into the furniture carcass 4 up to the closed end position. In order to provide a defined Eindrückweg available in terms of a touch-latch functionality of the ejector 2 in the closed end position of the drawer 3, corresponding, known in the art, spring buffer may be provided. These can be arranged, for example, on the inside of the front panel of the drawer 3 or on the side walls of the furniture body 4. The ejection device 2 is now positioned as intended and can be fixed by fixing the support member 7 on the bottom of the cabinet 6 of the furniture body 4 in the correct position relative to the rear wall of the drawer 3. In addition, after removing the spacer 15 from the ejection device 2, it is ensured that the triggering path for the ejection element 18 required for the touch-latch function of the ejection device 2 is available.
