Description

The present invention relates to a drilling jig with a base body, in which at least one opening for guiding a drill and / or a marking tool is arranged, and at least one stop which can be placed on an edge of a, in particular plate-shaped, workpiece to be machined and which is relatively is adjustable to the base body. In addition, the present invention relates to a method for assembling at least one furniture fitting in and / or on a, in particular plate-shaped, workpiece by means of such a drilling jig.

When assembling furniture, the fitters usually proceed according to a given plan. Various panel-shaped workpieces (mostly panel-shaped wooden elements) are assembled using appropriate fasteners for the furniture body. At least one movable furniture part (for example a drawer, a furniture door or a furniture flap) is then attached to this furniture body by means of a furniture fitting. Such a furniture fitting can be, for example, a pull-out guide, a hinge, an actuating arm arrangement or the like. In order to mount this furniture fitting at the appropriate point on the furniture body, especially on a plate-shaped workpiece of the furniture body, drilling jigs are used. A drill hole and / or a fastening position is marked by means of a drill and / or a marking tool via such a drilling jig. Then the furniture fitting is fastened with fastening means in the position given by the drilling jig.

The object of the present invention is to create an improved drilling jig and an improved method. In particular, the drilling jig should support a fitter in the assembly of the furniture fitting in an automated manner as possible. Sources of error should be reduced and the accuracy increased. In addition, one and the same drilling jig should be used when assembling as many different furniture fittings as possible

can be used.

This is achieved by a drilling jig with the features of claim 1. Accordingly, it is provided according to the invention that the at least one adjusting means comprises at least one electromotive drive, at least one interface to at least one

a memory is provided in which at least a first and a second

Data record for a drilling pattern of a furniture fitting to be arranged on the workpiece can be stored, and at least one control device is provided which is connected or can be brought into connection with the at least one electromotive drive and the at least one interface with the at least one memory, the at least one drive by means of the at least one control device as a function of one of the at least one memory

called data record can be controlled.

An automatic drilling jig is thus created, via which the fitter is given a drilling pattern for the furniture fitting to be installed. This means that the fitter no longer has to create the drill holes or mark the fastening position using a table or a furniture construction plan, but this is specified by the "intelligent" drilling jig.

Preferred embodiments of the present invention are given in the dependent claims.

According to a preferred exemplary embodiment, it is provided that the control device has a control core, an application program and an operating unit connected or connectable to the control core for signaling purposes, wherein operating commands can be entered by a user via the operating unit

A certain selection of data records does not have to be selected in advance and permanently saved in the drilling jig.

According to a preferred exemplary embodiment, it is provided that the at least one first and second data record can be created using a body configurator. With such a carcase configurator, different sizes and dimensions of furniture can be configured individually. This individual configuration then results in corresponding positions for the drill holes or fastening positions for the furniture fittings, so that corresponding data records for drill patterns are also generated. Specifically, such a cabinet configurator can be accessed and used on the applicant's homepage (see the Blum® product configurator at blum.com).

For the energy supply of the drilling jig, it can be provided that an energy store, preferably a battery or a (rechargeable) accumulator, to supply the at least one adjustment means and the control device with

In Fig. 1, a starting point is shown schematically before assembling a piece of furniture 100.

The furniture body 101 consists of several, already assembled, plate-shaped workpieces W. Specifically, these are a base plate, two side walls, a cover plate and a rear wall.

Furthermore, the furniture 100 comprises a movable furniture part 102. In the illustrated embodiment, this movable furniture part 102 comprises two plate-shaped workpieces W, which ultimately form a furniture flap in the form of a so-called lift-up door.

Furthermore, several furniture fittings 50 are shown schematically in FIG. 1. Specifically, this not yet assembled piece of furniture has 100 furniture fittings 50 in the form of

four hinges 51 and in the form of two actuating arm devices 52.

In addition, a drilling jig 1 is shown schematically in FIG. 1. As essential components, this drilling jig 1 comprises a base body 2, in this case two movable stops 3 mounted on the base body 2 and several openings B for guiding a drill and / or a marking tool.

In Fig. 2, the drilling jig 1 is still schematically, but somewhat enlarged,

shown together with the other logical components.

The control device 6 has a arranged in the base body 2 of the drilling jig

Control core 61 (z. B. a microprocessor).

In addition, the control device 6 has an operating unit 63. In the illustrated case, the operating unit 63 is designed as a mobile terminal 66.

An application program 62 of the control device 6 can be called up and executed, for example, in the form of a mobile app on the mobile terminal 66.

The operating unit 63 in the form of the mobile terminal 66 has a screen 64, in this case touch-sensitive, and an input device 65, in the illustrated case in the form of a keyboard that can be displayed and operated on the screen 64.

The mobile terminal 66 is connected to the base body 2 (in particular to the control core 61) via a wireless communication interface 68, in this case for example via Bluetooth.

Operating commands can be entered by a user via the operating unit 63

will.

The drilling jig 1 has at least one interface 5 to at least one memory S. This memory S can be designed as a physical component in the base body 2 of the drilling jig 1 and can be connected to the control core 61 of the control device 6. Preferably, however, it is provided that - as shown schematically - the memory S can be accessed from the control device 6 via the interface 5 (and for example via the intermediate operating unit 63) via cloud computing (see the cloud shown schematically). In the memory S there is at least a first and a second data record D1, D2 for each drilling pattern of an am

Workpiece W to be arranged furniture fitting 50 is deposited.

In the case shown, the data records D1, D2 are not permanently stored, but can be called up at any time in a cloud-based manner and are therefore always up-to-date.

During assembly, a data record D1 or D2, stored in the at least one memory S, of a drilling pattern of the furniture fitting 50 to be mounted on the workpiece W is then called up by means of the at least one control device 6.

This call can be initiated by the fitter. For example, the fitter enters a corresponding article number via the operating unit 63. However, it can also be provided that the fitter records an identification means (e.g. a QR code) via the operating unit 63. Alternatively, it is also possible that the at least one first and second data record D1, D2 can be created using a body configurator and

can be called up via the operating unit 63.

Next, during assembly, the at least one stop 3 of the drilling jig 1 is adjusted by means of the at least one control device 6. For this purpose, the electric motor drives 41 of the adjustment means 4 shown in dashed lines in FIG. 3 are controlled accordingly.

The energy supply takes place in that an energy store 7 for supplying the at least one adjusting means 4 and the control device 6 with energy is arranged in the base body 2.

Specifically, the setting of the positions of the stops 3 relative to the base body 2 takes place as a function of the data record D1 or D2 called up from the at least one memory S. As illustrated in FIG. 3, the stop 3 shown on the left is extended less far from the base body 2 than the stop 3 shown below.

The next step during assembly is the placement of the drilling jig 1 on the workpiece W. In FIG. 4, a part of such a plate-shaped workpiece W is shown for this purpose. This workpiece W has edges K (two at right angles to one another). The drilling jig 1 is placed on the workpiece W to be machined in such a way that the stops 3 lie flush against the edges K. If desired or helpful, the drilling jig 1 can be releasably fixed on the workpiece W via a holding element (not shown).

If the drilling jig 1 is arranged as in FIG. 4, the fitter can for example be shown on the screen 64 of the operating unit 63 which openings B

are now to be used for the drill or the marking tool.

Alternatively (or additionally) it can also be provided that display means 10, preferably in the form of light-emitting diodes, for identifying at least one of several openings B provided in the base body 2 can also be provided on the base body 2

are arranged.

In this context, FIG. 4 shows by way of example that the display means 10 provided with a cross are active. This means that a drilling or marking should be carried out precisely in the openings B assigned to these two display means 10. Here, the fitter can also use color gradations or a flashing light

additional information (e.g. drilling depth, drilling width, etc.) can be displayed.

Then, as illustrated in a schematic section in FIG. 5, a drill 11 is inserted or introduced into a corresponding opening B in the base body 2 of the drilling jig 1. A borehole L is then produced in the workpiece W at the position of the at least one opening B in the base body 2.

Alternatively, a fastening position for at least one fastening means can also be marked at the position of the at least one opening B of the base body 2.

As soon as all the holes or markings have been made, the drilling jig 1 can be removed from the workpiece W again. In FIG. 6, only the workpiece W together with the two drill holes L formed in the workpiece W according to the predetermined drilling pattern is shown by way of example.

As the next step, a furniture fitting 50 is then fastened to the workpiece W via the previously produced drill holes L (or via marked fastening positions). Specifically, it is schematically illustrated in FIG. 7 that a furniture fitting 50 in the form of a hinge 51 is mounted on the workpiece W via corresponding fastening means 53 (for example in the form of screws).

The same procedure is then chosen for the further furniture fittings 50 and workpieces W until finally the furniture 100 is completely assembled. In Fig. 8 is a side sectional view of a furniture body 101 including folded up, movable furniture part 2 and the furniture fittings 50 in the form of

Hinges 51 and an actuating arm device 52 are shown.

In FIG. 9, a piece of furniture 100 is shown in perspective in the assembled state, the movable furniture parts 102 being designed here as drawers mounted in the furniture body 101 that can be moved. These drawers are each slidably mounted on the side walls of the furniture body 101 via furniture fittings 50 in the form of pull-out guides.

10 shows an assembled drilling jig 1 in a perspective view. In the embodiment shown, eight openings B for guiding a drill 11 and / or a marking tool are formed in the base body 2. The base body 2 is essentially cuboid.

On two sides of the base body 2, two stops 3 are mounted so that they can be extended and retracted. These stops 3 are arranged at right angles to one another. The stops 3 are each as plate-shaped elements with a base body 2 facing,

flat stop surface formed.

The stops 3 can each be adjusted via a movement transmission element 42 from the adjustment means 4 (not shown).

In addition, two guide pins 92 are provided for each stop 3. These guide pins 92 together with the corresponding guide recesses 91 formed in the base body 2 form the guide means 9.

11 shows a perspective exploded view of the drilling jig 1. Essentials

Components - which can already be seen in FIG. 10 - are the base body 2 and the stops 3.

In Fig. 11, the guide pins 92 and the guide recesses 91 are the

Guide means 9 clearly visible.

The movement transmission elements 42 are designed as toothed racks and are connected to the stops 3.

The base body 2 has numerous housing elements 23, by means of which the various components arranged in the base body 2 are covered or

be locked.

The openings B in the base body 2 are designed in the form of sleeves that can be inserted into the base body recesses 24. It can be provided that (e.g. ring-shaped) light-emitting diodes are arranged on the end faces of these sleeves,

which form the display means 10.

Two adjustment means 4 in the form of electric motor drives 41 are arranged in the drilling jig 1. Each electric motor drive 41 has an electric motor 43, a drive shaft 44 driven by the electric motor 43 and a drive means 45 arranged on the drive shaft 44, specifically in the form of a gear wheel corresponding to the movement transmission element 42.

When the drive means 45 rotates, this gear-shaped drive means 45 meshes with the rack-shaped movement transmission element 42 so that - depending on the direction of rotation - the stop 3 connected to the movement transmission element 42 is retracted or extended accordingly.

As soon as the desired position of the stop 3 relative to the base body 2 is reached, this position can be fixed by means of locking means 8. For this purpose, in the base body 2 (in this case four) locking means 8 (specifically in the form of clamping jaws) for locking

of the at least one stop 3 is arranged relative to the base body 2.

It is preferably provided that the clamping jaws of these locking means 8 each encompass a guide pin 92. When the desired position of the stop 3 is reached, the locking means 8 are activated. This activation can be done manually, for example

be carried out by the fitter or will have appropriate

Activation elements carried out by the control device 6.

In FIG. 11, the control core 61 is arranged as part of the control device 6 in the base body 2 of the drilling jig 1. This control core 61 is signaling with the

electric motor drives 41 connected.

In Fig. 12, the assembled drilling jig 1 with completely retracted stops 3 is shown in perspective.

FIG. 13 shows the drilling jig 1 according to FIG. 12 in a top view. The movement transmission elements 42 and the guide pins 92 can also be seen.

FIG. 14 corresponds in perspective to FIG. 12, but here the stops 3 are fully extended.

FIG. 15 shows a top view of the drilling jig 1 according to FIG. 14.

In FIG. 16, a drilling jig 1 together with a plate-shaped workpiece W is shown in perspective. FIG. 17 shows a plan view corresponding to FIG. 16. The stops 3 are each in intermediate positions and are extended to different extents relative to the base body 2. The base body 2 of the drilling jig 1 lies flat on the surface of the workpiece W. The stop surfaces of the stops 3 facing the base body 2 lie flush against the edges K of the workpiece W.

Starting from this position, boreholes L can then be produced in the workpiece W at the positions of the predetermined openings B and / or a fastening position for at least one fastening means can be marked at the positions of the predetermined openings B. In FIG. 16, on the right-hand side of the workpiece W, such drill holes L have already been made.

Finally, FIG. 18 shows another exemplary embodiment of a drilling jig 1, in which the operating unit 63 is designed as a control panel 67 arranged on the base body 2.

In this exemplary embodiment, it is preferably provided that the entire control device 6 and the memory S are physically integrated in the base body 2 of the drilling jig 1.
