Description

The present invention relates to a device for opening and / or closing of drawers, with a pullout guide, which has at least one fixable on a furniture body guide rail and a movably mounted track, wherein on the running rail a drawer with a front panel is fixed and a holding element with a Activator is provided, wherein the activator can be coupled with an opening and / or closing mechanism for the drawer and a method for calibrating such a device.

From the EP 1845821 a drawer closing and opening device is known in which a latching mechanism is provided to lock the drawer in a closed position on the furniture body. By depressing the front panel of the locking mechanism can be unlocked and moved by the force of a spring in the opening direction. In order to adjust the joint spacing between the front panel of the drawer and an adjacent end face of a furniture body, a rotatable adjusting wheel is provided on the locking mechanism, which allows a corresponding adjustment of the front panel over numerous components coupled together. In order to carry out an adjustment process, the setting wheel must first be made accessible and then rotated. Subsequently, a setting by the adjusting wheel must be made by opening and closing several times, the adjustment process is cumbersome and also numerous components for a corresponding adjustment are required.

It is therefore an object of the present invention to provide a device for opening and / or closing of drawers, wherein the distance between a front panel and the furniture body is adjustable in a simple manner.

This object is achieved with a device having the features of claim 1 and a method with the features of claim 15. According to the invention, the device for opening and / or closing drawers comprises a holding element and an activator, wherein the activator for adjusting the distance of the front panel from the furniture body is slidably mounted on the holding element and can be fixed in different positions on the holding element. As a result, the activator only has to be pushed into the desired position, which can also be done with the drawer mounted. When the front panel is located in the desired position, the activator need only be fixed to the support member to maintain the predetermined distance of the front panel of the furniture body. The device can thus be simple in construction, in the best case, only two components for adjustment are required.

According to a preferred embodiment of the invention, the activator is mounted displaceably in a direction parallel to the longitudinal axis of the running rail. As a result, the activator can be easily moved in the opening and closing direction of the drawer. The activator is preferably latched to the holding element, so that a simple assembly is possible.

Preferably, the activator is independently adjustable during the first closing operation of the drawer. The user only has to mount the drawer on the two rails and then move to the closed position. In this case, the activator can be automatically moved to the desired position on the holding element, so that no complex multiple opening and closing of the drawer is required for the adjustment process.

For a simple coupling of the activator to the holding element, this is preferably mounted pivotably on the holding element. The activator can be displaceable along an axis on the holding element, so that a pivoting movement can be used for locking. For a simple fixation of the activator on the holding element, a plurality of teeth are provided on the holding element, which are in the fixed position of the activator at least partially in engagement with teeth on the activator. As a result, a latching with small distances is possible, in particular, forces between the activator and holding element can be distributed to a plurality of teeth. The activator will be in front and held in a frictional manner during the calibration process in the sense of a transition fit on the axis in its respective position up to the locking after calibration. Thus, vibrations or vibrations during the calibration process can not change the position of the activator on the axis. To change the position of the activator on the axle, the friction must be overcome by applying a force.

In a further embodiment, the activator is coupled to a driver which is movable along a housing. It can be provided on the housing a removable attachment for the driver. This allows for easy installation, since the user only has to move the drawer into a closed position, in which case the activator is positioned in the closed position on the holding element. Subsequently, the attachment is removed from the housing, so that after removal of the definition, a detent recess is present and the travel and the opening gap is predetermined by removing the fixing. The opening gap is the manufacturer defined by the positioning of the control element in the control cam spaced from the detent recess and the fixation of this position by the insertion of a determination. The triggering path results from the distance between the lowest point of the detent recess and the position of the angled end of the control element at the beginning of a distance groove effective in the closing area. The angled end of the control should preferably be loaded only on train and not on pressure. The distance groove forms a safety area to avoid stress on pressure. If a large trip path is desired, the spacer groove must be extended and the angled end of the control element is held in the fixed position within the spacer groove.

The calibratable activator may be coupled to a driver of a latch mechanism for opening the drawer. This can be designed as a so-called "ejection mechanism", so that it is unlocked by inserting the drawer and moved by a spring in the opening direction. In addition, the invention may also be coupled together with an ejection device for opening the drawer, for example a mechanically or electrically driven ejection device.

The device for opening and / or closing can also be designed as a self-closing device for drawers. Then the calibratable activator can also be coupled to the driver. In the embodiment as a self-closing device spacer elements between the front panel and the furniture body are preferably introduced, which are then removed after calibration.

An ejection device or a self-closing device prevents unwanted opening of a drawer from the closed position.

To carry out the adjustment of the diaphragm gap, spacer elements of defined thickness are preferably provided. They are inserted during the first closing process between the front panel of the drawer and the furniture body. After the first closing, the spacer elements can be removed so that the furniture has a defined aperture gap between the front panel of the drawer and the furniture body. This procedure must be carried out simultaneously on both sides of the front panel of the respective drawer.

In a method according to the invention for calibrating a device for opening and / or closing drawers, a drawer is first moved in the closing direction in such a way that the front panel of the drawer rests against a furniture carcass. The distance between the angled end of the control element and the detent recess in the control cam corresponds to the gap required for activating the ejection device between the front panel and the furniture body. Subsequently, a movable activator is fixed to a coupled with a running rail of a pullout guide member with the drawer open. After the fixation of the activator the determination for the driver in the locking mechanism for the drawer is removed so that then the drawer can be opened and closed, so that the drawer is locked to at least one control cam in a spaced-apart position from the furniture body. This allows a simple adjustment of the gap between the front panel and furniture body done with mounted drawer. Alternatively, the determination when first closing the drawer after calibration and the locking of the activator after passing a front projection on the driver can be removed from its position and released the driver and thus the locking mechanism. It is also conceivable that the determination is sheared off by the latched activator when first closing the drawer.

Furthermore, the activator can be pivoted by a device on the guide rail during the first opening of the drawer after the calibration and locked on the support member. The device is designed so that it no longer comes into contact with the activator during later use of the drawer. The activator jumps after the contact in the sense of a "crackle frog" to the holding element to stay there in the locking position.

Preferably, when the drawer is moved in the closing direction, the activator is simultaneously displaced on the holding element for an independent calibration. The movement of the drawer up to the stop therefore serves to adjust the front gap and to move the activator on the holding element. The position of the stop defines the gap between the front panel and the furniture body.

It is also possible to carry out the calibration procedure after a piece of furniture such as furniture has been moved. in a move, to repeat as often as you like.

A device for opening and / or closing drawers comprises a pull-out guide 1 which can be mounted on a furniture carcass. In this case, a pullout guide 1 is mounted on opposite sides of a furniture body. Each pullout guide 1 comprises a guide rail 2 which can be fixed to the furniture body and at least one movably mounted running rail 3, on which a drawer is fixed. In addition, the pullout guide 1 can comprise at least one center rail extending between the guide rail and the running rail to achieve a full extension.

In order to adjust a gap of a front panel of the drawer to the furniture body, a holding element 4 is fixed to the running rail 3, on which an activator 5 is slidably mounted on an axle 40. The activator 5 can be fixed to the holding element 4 and engages in a driver 7, which is part of a locking mechanism 17 for opening and / or closing the drawer. The driver 7 is arranged in a curved path 8 and fixed by a fixing 10 in a housing 6. In a closing region of the drawer, a calibration stop 19 engages the activator 5 against a contact edge 18 of the driver 7. A cam 12 has a Distanznut 16 for receiving a control element 13 during the calibration process. At the driver 7, the control 13 is articulated, the control 13 runs in the control cam 12th

The latching mechanism 17 comprises a spring element 9, which is arranged in a housing and is coupled via a rod 11 with the driver 7. Further, a removable attachment 10 in the form of a clamp is provided on the housing 6, which prevents in the delivered condition that the driver 7 is moved by the spring element 9 in a stop position in a pivoting range of the driver 7.

The locking mechanism further comprises the control cam 12, on which the control element 13 is movably mounted. The control element 13 is coupled to the driver 7. The control cam 12 includes a detent recess 14 in which the control member 13 is held by a spring of the spring member 9 when the drawer is in a closed position. If the drawer is pressed against the furniture body, the control element 13 runs against a run-on slope 15 and is thereby unlocked, so that then the force of the spring of the spring element 9 moves the drawer in the opening direction.

In order to adjust the distance of the front panel of the drawer to the furniture body, the activator 5 is slidably mounted on the support member 4. Like from the FIGS. 3A to 3D shows, the activator 5 is initially in an unlocked position and can be moved along an axis 40 on the support member 4. For this purpose, the activator 5 has an annular portion 51 which engages around the axis 40. The axis 40 is on opposite sides Holders 41 set. The holding element 4 further comprises two plate-shaped portions 42 which bear against the running rail 3 and on which rests webs 30 and 31 of the running rail and fix the holding element 4 in the longitudinal direction of the running rail 3. On the holding element 4, a strip with protruding teeth 43 is further provided, which protrude perpendicular to the longitudinal direction of the running rail 3. The teeth 43 serve to lock the activator 5. Furthermore, a latching edge 44 is formed on the holding element 4. To lock the activator 5 after the calibration process, at least one latching lug 54 is latched behind the latching edge 44.

The activator 5 is initially displaceably mounted along the axis 40. On the side facing the retaining element 4, protruding teeth 53 are formed on a middle section 51 and can engage the teeth 43 on the retaining element 4. Furthermore, the activator 5 comprises two projections 52 which can come into engagement with the driver 7.

In FIG. 4A the activator 5 has been displaced from the starting position along the axis 40, but not yet locked to the holding element 4. In the next step, this is pivoted about the axis 40 for locking the activator 5, so that a latching nose 54 on the activator 5 engages behind the strip 44. In the latched position, the teeth 43 and 53 are engaged with each other and prevent the activator 5 from being displaced along the axis 40. When re-closing the drawer of the latched activator 5 moves over the front projection 20 on the driver 7, the renewed insertion of the front panel 62 in the closing direction of the ejection mechanism can be triggered. Until release of the ejection mechanism, the front projection 20 on the driver 7 assumes a locking function for the drawer coupled to it via the activator 5 and the running rail 3.

In the FIGS. 5A to 5C the latching process of the activator 5 is shown on the holding element 4 again in detail.

In the Figures 6A and 6B the device for opening with shifted activator 5 is shown, which is moved along the axis 40 in the desired position has been. In this position, the activator 5 must be pivoted only by a slight pressure and the locking lug 54 on the activator 5 are latched to the locking edge 44 on the support member 4, which can also be done with mounted solid drawer.

In the FIGS. 7A to 7D a modified embodiment of a holding element 4 'is shown, which is mountable on a running rail 3. On the holding element 4 'receptacles 42' are formed on opposite sides, on which protruding webs 30 and 31 of the running rail 3 can engage. This results in a particularly positionally accurate fixing of the holding element 4 '. The activator 5 is formed as in the previous embodiment, but includes a bent locking lug 54 'for locking on the strip-shaped projection 44' on the holding element 4 '. Due to the curved shape, a smooth locking of the activator 5 on the holding element 4 'can be achieved, as well as a smooth release by overstretching the bent locking lug 54' achieve.

In the FIGS. 8A to 8C a furniture 60 is shown before a calibration process, which has a furniture body 61, on which on opposite inner sides in each case a pullout guide 1 is mounted, by means of which a drawer with a front panel 62 is movably mounted. Before the calibration process, a relatively large gap L between the front panel 62 and the furniture body 61 is present.

The FIGS. 9A to 9D show the device for opening before a calibration process. The activator 5 is mounted displaceably on the holding element 4 and the control element 13 is guided in the control cam 12.

For the calibration process ( Figures 10 and 11 ), the front panel 62 is first pressed against the furniture body 61, so that no gap L longer exists. In this case, the activator 5 is displaced along the holding element 4, since the activator 5 rests with the calibration stop 19 of the activator 5 at the contact edge 18 of the driver 7 which is intended for calibration. The driver 7 is fixed by the manufacturer with a fixing 10 in the housing 6. By the manufacturer of the pullout guide 1, the required trip path for the ejector thus established. When reopening the drawer of the still tipped driver 7 runs past the front projection 20 of the driver 7. After opening the drawer, the activator 5 is now latched and fixed to the holding element 4. Furthermore, the fixing 10 is removed from the housing 6. When the drawer is first closed after latching of the activator 5 on the holding element 4, the activator 5 passes over the front projection 20 on the carrier 7 in order to reach its functional position.

In the FIGS. 12A to 12C the furniture 60 is shown after the calibration process. The front panel 62 is arranged in a latched position, in which the control element 13 is held in the detent recess 14 of the control cam 12, at a small distance to the furniture body 61, wherein the distance 1 is smaller than the large gap L before the calibration. By pressing the front panel 62 against the furniture body 61 can now be done unlocking of the control element 13 on the control cam 12. The calibration process sets the trip path required for the safe trip. The calibration process after the construction and installation of the furniture eliminates all detrimental tolerances for the deployment process and gives the customer an ejection mechanism with a very high level of functional reliability and a clean aperture image.

The Figs. 14A to 21C show modified furniture and device for opening and / or closing of drawers, before, during and after a calibration process.

The FIGS. 14A to 14C show a piece of furniture 60 with a furniture body 61 with a drawer with a front panel 62 before the calibration of the gap L between the front panel 62 and the furniture body 61. In this initial situation, the gap L has no defined dimension, it may be larger or smaller than a predetermined Be target size.

The FIGS. 15A to 15C show a pullout guide 1 with a Selbsteinzugsvorrichtung 70 with a damper 71 and the driver 7 before calibration of the gap L. The self-retracting device 70 is corresponding to opposite sides of a drawer FIGS. 14A to 14C assembled.

The FIGS. 16A to 16C show the beginning of the calibration process. First, U-shaped spacers 72 were slid over the front panel 62. The thickness of the plate-shaped region 73 of the spacer element 72 corresponds to the target size for the gap L after the calibration process. After pushing the spacer elements 72 on the outer edges of the front panel 62 of the drawer is closed, as shown in the FIGS. 18A to 18C is shown. When closing the displaced on the running rail 3 is still relative to the running rail 3 movably mounted activator 5 and moved to a defined position, as shown in the FIGS. 17A to 17C and 19A to 19C evident.

The FIGS. 20A to 20C show the furniture 60 after the calibration process. The gap 1 now has a defined dimension corresponding to the target size.

The FIGS. 21A to 21C show the pullout guide 1 with the Selbsteinzugsvorrichtung 70 after the calibration. Previously, the activator 5 was locked by pivoting on the teeth 43.

When calibrating the activator when using a Selbsteinzugsvorrichtung 70 tolerances between the body and activator are compensated. It is also the setting of a zero aperture gap possible. The diaphragm gap when using a Selbsteinzugsvorrichtung 70 is determined only by the thickness of the spacers 72 in the region 73.
