Description

Side frame assembly with furniture pullout guide

The invention relates to a side frame assembly with furniture drawer guide according to the preamble of claim 1.

Various adjustment devices for aligning the front panel of a drawer are known from the prior art. Despite this adjusting the alignment of the front panels is still relatively cumbersome and time consuming.

The invention has the task of breaking new ground when aligning the front panel of furniture against this background.

The invention provides a side frame assembly with furniture pullout guide having one or more adjustment means for adjusting the distance between the side frame assembly and the furniture pullout guide. By adjusting the relative position between these two units, it is also possible in a simple manner on a drawer to align the attached in this case to the one- or multi-piece side frame assembly front panel with.

It is particularly advantageous according to a development to be regarded as an independent invention, when the adjusting device has two adjusting wheels, one of which is accessible from one side of the side frame assembly and the other from the other side of the side frame assembly. In this way, the front panel can be aligned with a hand tool or a cordless screwdriver or the like during initial assembly from the inside, eg with an alignment system or from the outside, in particular when loaded. With sufficient guidance of the tool and the adjustment on both sides, ie, accessible from the inside and the outside adjustment is possible. It is also structurally advantageous if the adjusting device has a base member having a base leg and two side legs perpendicular thereto, wherein the provided with a through hole base leg is penetrated by a screw and wherein the screw at its projecting between the two side legs in a nut is screwed with a toothing, which meshes with gears on the adjusting wheels.

Preferably, the set screw with its screw head is securely supported on a running rail of the furniture drawer guide.

According to a further variant, it is advantageous if the adjusting screw is non-rotatable relative to the running rail.

The handling is particularly easy when the adjusting wheels a

Having torque transmission contour for a corresponding actuating tool or an actuator of an alignment system.

It is expedient if, according to a preferred variant, two of the adjusting devices offset in the pull-out to each other at the

Side frame assembly are distributed to ensure a particularly uniform setting.

The invention also provides for solving the problem a method for aligning at least the front panel of a movable on / in a furniture body in an open and a closed position furniture part, in particular a drawer, a piece of furniture, with the aid of an alignment system with at least one motor-driven adjusting unit for adjusting at least one or more adjusting device (s) for aligning the front panel, characterized by the following steps: a) detecting an actual state of the orientation of the front panel relative to the furniture body and / or other adjacent furniture parts in closed state of the drawer with at least one connected to a control computer measuring device; b) determining at least one compensating movement to be performed on one or more adjusting devices of the drawer for adjusting the orientation of the front panel on the basis of the detection of the actual state of step a); and c) performing the at least one compensating movement with the at least one motor-driven setting unit.

Unlike in the prior art, such alignment does not take place with a manually operable tool or, for example, a mere cordless screwdriver or the like "on sight" but controlled or regulated on the basis of at least one measurement, an evaluation of the measurement with a computer and a "Automatic" 'Performing a compensation movement / adjusting movement to correct the position of the front panel. This process is simple, reliable, fast and accurate.

In this case, steps b) and c) are particularly preferably passed through repeatedly so that a particularly precise alignment of the front panel takes place automatically and in a simple manner.

The invention also provides an alignment system for carrying out the method, having the following features: at least one measuring device or a plurality of the measuring devices for detecting a zustandstzustandes the orientation of the front panel of the movable furniture part, in particular of the drawer, the furniture relative to a

Furniture carcass in the closed state of the drawer; a control computer connected to the at least one measuring device for determining at least one at one or more adjusting devices of the drawer for adjusting the orientation of the front panel to be performed

Compensating movement; and at least one or more motorized actuating unit (s) for adjusting the at least one or more adjusting the movable furniture part.

This alignment system has a simple design and yet enables a preferably automated alignment of the front panel quickly and precisely.

It is advantageous if each measuring device has at least one or more sensor element (s) for detecting the distance of the front panel to the furniture body and / or to an adjacent drawer. In this way, the measuring device can be realized inexpensively and particularly easily.

It is expedient if each measuring device has an attachable to the edge of the front panel sensor carrier on which one or more of the sensor elements is / are arranged. The sensor carriers are quickly distributed for measurement on the furniture part and thus enable a feasible in a short time measurement of the given gap widths on the front panel.

According to a structurally particularly simple variant, the sensor carriers are U-shaped and have one of the sensor elements on its base leg and one of the sensor elements on one of the side legs. In this way, it is easy to determine the distances between the front panel and horizontally and vertically adjacent elements of the cabinet.

It is also advantageous if each control unit each has one or more preferably electric drive unit (s) and depending on the number of drive unit (s) one or more output shafts with a torque transmission contour, which is designed to each with a corresponding torque transmission contour of the adjustment of the drawer to work together. Preferably, the output shafts are at least partially designed as flexible shafts.

It is also useful if each actuator has a torque arm for supporting the actuator on the drawer or furniture body.

According to one variant, a refinement as a motor-operated hand tool is also particularly advantageous.

It is also conceivable to use a corresponding alignment system for setting a door on a furniture carcass. In the meaning of the claims then corresponds to the front panel of the door, which is also in this case in one piece and the movable furniture part.

Advantageous embodiments of the invention can be found in the dependent claims.

The invention will be described in more detail by means of exemplary embodiments with reference to the drawing. It shows:

Fig. 1 and 2 show a piece of furniture 1 with a furniture body 2 and three extendable from the furniture 1 furniture pull-outs, which are designed here as drawers 3a - 3c. This number of drawers 3 is to be understood purely by way of example. At least a drawer is provided.

According to Fig. 1, each of the drawers 3a - 3c on a front panel 4a - 4c, which is as parallel to the leading edges 5, 6 of the front side 7 of the furniture body to align. For this purpose, the horizontal distance between the front panels 4 a - 4 c to the front 7 must be as constant as possible.

It is also desirable if the individual front panels 4a, 4b, 4c of the various furniture extensions 3a, 3b, 3c lie in one plane and are also aligned parallel to one another, i.e., in a plane. the gaps 8 between adjacent front panels 4a, 4b and 4b, 4c (as well as other vertically spaced furniture parts such as a countertop or the like) should be as evidently as possible identical (Figure 1).

To achieve this, it is known to provide one or more adjusting devices for aligning the respective front panel 4 on the individual drawers 3. The alignment can be done for example by aligning the front panel 4 alone relative to the rest of the drawer or by aligning the front panel with side frame assembly relative to the bottom of the drawer or relative to the pullout guides.

According to Fig. 7 and 8 is provided to realize the front panel adjustment characterized in that each of the side frame assemblies 22, 23 of the at least one drawer 3a, 3b, 3c with the bottom 9 and the rear wall 10 adjustment 12 are assigned, which are designed , the side frame assemblies 22, 23 with the front panel 4 and thus here even the entire drawer relative to the pullout guides 36 with a carcass rail 37 and at least one running rail 38 to hang the drawer to adjust (see also Fig. 12, 13).

The adjusting devices 12 have a base element 13, which is designed here as a side view of a U-shaped frame part, which has a base leg 14 and two side legs 15, 16 perpendicular thereto (see FIG. 14 and FIGS. 10 to 13). The provided with a through hole base leg is penetrated by a screw 1 1.

At its between the two side legs 15, 16 projecting end of the screw is screwed into a nut 17 with a bevel gear teeth, said bevel gear meshing with corresponding teeth 18 of rotatably mounted in through holes of the side legs 15, 16 adjusting wheels 19, 20. These adjusting wheels 19, 20 also have a respectively accessible from the opposite outer sides of the side legs 15, 16 approach lug contour 21 (in the sense of a torque transmission contour) for an actuating tool. Here, this contour is as a polygonal socket for applying an outer polygon of a tool, e.g. an allen wrench or a cordless screwdriver having an attachment with an external polygon or the like. It is also conceivable that the approach contour is designed continuously, so that it can be penetrated by the tool. Thus, even an adjusting 19 or 20 omitted on each adjusting device 12. In a different design of the adjustment 12 can be arranged with both sides frontal accessibility as adjusting 19 or 20, a worm (not shown) and instead of the bevel gear on the circumference of the nut 17 a corresponding Schneckenradverzahnung (not shown).

The adjusting devices 12 are integrated into the side frame assemblies 22, 23 or associated therewith in such a way that one of the adjusting wheels 19 is accessible from the inside of the drawer in the extended state of the drawer in the furniture carcass (FIGS. 8 and 9b) and the other of the adjusting wheels 20 in the extended state of the drawer 3 is accessible from the outside (Fig. 8 and 9a).

Thus, the possibility is advantageously created to adjust the inclination of the drawer 3 together with the front panel 4 from the outside, which is advantageous, for example, when the drawer 3 is filled, and on the other hand from the inside, which is particularly advantageous if for the adjustment of the

Drawer 3 a - to be described in more detail below alignment system 24 - is used (Fig. 2). It is also advantageous to be able to readjust a loaded piece of furniture in order to be able to enable the desired "apparently identical" column 8 even in the practical use of the piece of furniture after the so-called "setting".

At its end remote from the two side limbs 15, 16, the adjusting screw 11 (FIG. 14) may, according to a particularly preferred variant, have a screw head 25. This screw head 25 is preferably not rotationally symmetrical to the axis of rotation of the screw. According to the illustrated embodiment, it has a rectangular shape in a plan view perpendicular to the axis of rotation of the adjusting screw 1 1. The adjusting screw 1 1 passes through a correspondingly contoured bore of an angle or a rail 27 of the side frame assembly 22 and is supported axially on the running rail 38 of the furniture drawer slide 36, on softer the drawer or the side frame assembly rests. The head of the screw 1 1 can also be supported laterally on a corresponding wall of the side frame assembly.

In this way, the screw 1 1 is held against rotation.

Preferably, however, more of the legs 14, 15, 16 of the adjusting device 12 are rigidly connected to a part of the side frame assembly 22 or even bent directly out of the material of a part of the side frame assembly 22.

By turning on one of the two adjusting wheels 19, 20, the nut 17 is rotated on the adjusting screw 1 1, so that the nut 17 moves on the adjusting wheel 20 in the axial direction, so that the distance between the nut 17 (and thus the

Running rail 38) and the screw head 25 of the adjusting screw 1 1 is changed (Fig. 12, Fig. 13).

As a result, the distance between the running rail 38 and the respective side frame assembly 21 is changed, resulting in a suitable distribution of the one or more adjusting device (s) on the two side frame assembly, that the angle of inclination between the track 38 and the side frame assembly 22 changes, which in turn results in a change in the front bending position and orientation.

Preferably, in each case two of these adjusting devices 12 are arranged distributed in the pull-out to the two side frame assemblies 22, 23, in particular one half of the side frame assembly 22 closer to the front panel 4 and one half of the side frame assemblies 22 farther from the front panel the orientation of the front panel 4 are particularly advantageous easily and quickly changed.

The adjusting device is used and supplemented particularly advantageously with the motorized alignment system 24 (FIG. 2) to be described below.

This alignment system 24 preferably has a central processing unit 30 with a control computer (not shown here) to which one or more measuring devices or devices 31 are connected via a wireless connection or via one or more lines 26, one or more sensor elements 3 Ia, 31 b have.

The control computer 43 is in turn connected to one or more actuators (here all housed in the central unit 30) to control them.

The opened central unit is shown in FIGS. 16 a - g. Each control unit has at least one drive, for example an electric adjusting motor 39, possibly a transmission and at least one output shaft 28 with a torque transmission contour 41, for example an external polygon. Preferably, the actuator is further provided with means for torque support on the drawer bottom (not shown). Advantageously, the required torque support can be realized even by a sufficiently large net mass of the central unit 30. It is conceivable that each adjusting device 12 of the drawer 3 to be aligned in each case is assigned directly to one of the actuating units and that these are only controlled centrally by the control computer. In this case, could be dispensed with the flexible waves.

But it is also conceivable that an actuating unit a plurality of drive units, in particular electrical adjusting motors 39, and a plurality of output shafts 28 with a corresponding torque transfer contour 42 (see Fig. 15 a, b) corresponding to the corresponding torque transmission contour (shoulder contour 21) on the adjustment 12th (see Fig. 15 c, d) is formed. In Fig. 2, the output shafts are formed as flexible shafts.

Preferably, the adjustment of the bezel inclination with the alignment system 24 is controlled or regulated.

The electronic alignment system is thus temporarily inserted by the furniture fitter in intended for setting drawer and brought into operative connection with the adjusting devices 12 in the side frame assemblies.

Preferably, the actual position of the front panel is detected with the measuring device 31 relative to adjacent furniture parts and matched with a desired position, which is stored in the control computer. From this, an adjustment is calculated, which by driving the drive units of actuators from

Control computer is implemented. This step can be performed once or multiple times.

Thus, adjusted by tilt adjustment and height adjustment of the empty drawer 3 in the three spatial levels by means of the adjusting elements until the Joint distances parallel and equal to the body and the overlying or underlying furniture part "mediated" are.

Thus, adjusted by tilt adjustment and height adjustment of the empty drawer in the three spatial levels by means of the adjusting elements until the joint distances (column 8) and the distances of the front panel 1 to the furniture body 2 are parallel and equal.

Such adjustment is preferably done once during assembly of the furniture, including the alignment system 24 is attached once to the drawer 3 (Fig. 2), Once the adjustment is completed, it is removed from the drawer and used to adjust the front panel tilt of the next drawer.

Alternatively, all drawers of a piece of furniture can be controlled simultaneously by a higher-level computer, which then in each

Drawer one of the networked in this case alignment systems 34 is used.

It is also conceivable, in succession, to record the measured values one after the other with only one single measuring device 31 and / or to sequentially apply this actuating unit one after the other to the various adjusting devices with only one of the actuating units on the basis of the measurement and to control it (according to a predetermined scheme).

Also conceivable are other actuating units than those indicated in FIG. 2, for which, however, the number of revolutions for the flexible shafts in the electronic control unit still has to be reduced (cams, sliding wedges).

Also conceivable are, in particular, actuators without a torque support device on the drawer, which are held by the mechanic (in the manner of a hand tool). In the following, the preferred measuring devices 31 will be described in more detail.

The measuring devices 31, according to a preferred embodiment, each U-shaped sensor carrier 33 made of plastic or sheet metal, which are preferably placed in the region of the four corners of the front panel 4 on the edge thereof.

The sensor carriers 33 are preferably in the region of their base leg 34a with one of the sensor elements 3 Ia - a distance sensor - provided in the mounted state for vertical distance measurement, ie to measure the width of the gap to the adjacent front panel or to an upper or lower furniture wall ,

It is also advantageous if, in the region of a side leg 34b aligned at right angles to the base leg, they have a further sensor element 3 Ib -a further distance sensor-which is designed to determine the horizontal distance of the front panel 4 to the furniture body 2 (see FIGS 6). The sensor carriers 33 are preferably clamped on the front panel 4 from above and from below for the purpose of measurement (FIGS. 5, 6).

Alternatively, it would be conceivable to apply the sensor elements 31 a, 31 b directly with a slightly adhesive portion on the front panel (or the furniture body and the adjacent furniture parts to the front panel as parallel front panels). Alternatively, both sensor elements 31a, 31b may be arranged on a sensor carrier 33 designed as a two-legged angle, which has a slightly adhesive or slightly adhering contact section to the front panel.

In the embodiment in question are after the (approximately centered on the drawer bottom) inserting the electronic control unit, the four sensor carrier 33rd in the form of brackets, which contain the sensor elements 31 a, 31 b, aufzustecken on the front panel 4 below and above.

After insertion (closing) of the drawer, the receiver of the electronic control unit can receive a start signal via a hand-held device (eg wireless transmitter) and automatic adjustment takes place by stepwise adjustment with the distances determined by the sensor elements 3 I a, 3 I b to the carcass front surface and / or to the front panel edge of the adjacent drawer,

However, it is also conceivable to use only one of the measuring devices 31 and thus to record the measured values in succession.

In a further embodiment, an alignment of the front panels according to the above-described solution could take place by advantageously the adjusting motors 39 are not arranged in the central unit 30, but are directly coupled to the adjusting 19 or 20 of the adjusting device 12 via a rigid coupling (see FIG and 18).

According to this embodiment, the flexible output shafts 28 can be omitted and the central unit is connected only via electrical lines 41 with the adjusting motors 39 to the adjusting devices 12. FIGS. 19a shows in detail the coupling of the adjusting motor 39 with the adjusting device shortly before or after the connection with the adjusting device 12. In FIG. 19b, the adjusting motor 39 is brought into engagement with the adjusting device. The adjusting motor 39 is supported against rotation by the base 29 on the drawer bottom. For the axial securing known solutions from the prior art can be used, which therefore need not be explained here in more detail. There are further exemplary embodiments conceivable, for. For example, an automatic horizontal leveling can be achieved via an electronic capsule vial arranged in the electronic control unit.

According to another variant, a hand control on "visual distance" without the sensors from the handset by pressing a button is conceivable.

In a further embodiment, an alignment of the front panel by means of a motor-operated hand tool can be made, which integrally contains a measurement / evaluation unit for the gap or which is connected to such a measurement / evaluation unit.

This so-called "meter-cord or net screwdriver" could be used instead of a classic cordless or cordless screwdriver, without dispense with the advantageous and more accurate gap measurement by sensors.No sensors are to be attached to the furniture, as a contactless detection of the gap dimensions eg via laser measurement or touching by a touch sensor.

The measuring points, which preferably lie close to the corners of the front panel, are detected successively by manually guiding the measuring cordless screwdriver into the distance zone near the measuring point by activating the measured value recording. The display tells the user where to measure now.

The measuring distance is clocked off one after the other and read in. After reading in or after entering the termination of the measuring point detection, the evaluation calculates the adjustment paths for each adjustment 19, 20. The display specifies the user at which point should now be adjusted.

The coupling of the measuring cordless screwdriver to the respective adjusting wheel 9, 20 can take place in a prescribed sequence, or alternatively instead of a sequence of Ankuppeins can be detected when coupling the selected adjusting 19, 20 and operated with the calculated value.

Another advantage is the fact that the measuring cordless screwdriver as a hand tool from both the outside and the inside of the

Drawer can be applied. It can thus be used for adjusting also with loaded drawer.

Thereafter, in this case, the motor-operated handset preferably integrally has the measuring device or a plurality of measuring devices 31 for detecting an actual state of alignment of the front panel 4 of the movable furniture part, in particular the drawer 3, of the furniture 4 relative to a furniture body in the closed state of the drawer (wherein can also be connected to this) and connected to the at least one measuring device control computer for determining at least one at one or more Versteüeinrichtungen 12 of the drawer 3 to adjust the orientation of the front panel 4 to be performed compensating movement; and at least one or more motorized actuator (s) for adjusting at least one or more of the calibration devices 12.
