Description

[0001] Guide for applying at least one mark and / or hole to a workpiece

[0002] The invention relates to a device for making at least one mark and / or drilling on a workpiece, in particular a furniture component. The device comprises a base part with at least one stop and at least one slider movable relative to the base part, having at least one marking opening through which the workpiece can be marked and / or drilled.

[0003] For example, when assembling furniture or assembling prefabricated furniture yourself, there is often a need to make markings or drill holes at specific locations on a furniture component. These markings or holes can be used, for instance, for directly connecting furniture parts to each other or for attaching fittings and / or mounting elements to a piece of furniture. This could include, for example, markings for the cup holes of hinges, holes for dowels or screws to attach drawer runners, sliding door hardware, table fittings, or other furniture fittings such as locks and soft-close mechanisms.

[0004] Often, a single hole is not required, but rather a series of holes arranged in a specific geometry to form a so-called hole pattern. To facilitate marking the positions of the holes on the workpiece, printed hole pattern templates are available, which can be placed on the edges of the furniture parts using markings and on which the positions of the holes in the hole pattern are indicated.

[0005] In many applications, the drill hole pattern must be positioned at different locations on the furniture component, depending on the customer-specific configuration of the furniture or its installation situation. For this purpose, it is known to specify different stop lines on the aforementioned (paper) template for the different installation situations or configurations, or to repeat the drill hole pattern multiple times at different positions. This makes the template more complex and creates the risk of accidentally marking the position of unnecessary drill holes on the workpiece. Publication AU 2015202591 A1 discloses a jig for applying drill hole markings to a workpiece, consisting of two parts that can be moved relative to each other: a base part that is placed on the workpiece in a specific position and orientation, and a template that can be moved relative to this base part.The base part can be positioned, for example, using stops on the edges of the workpiece, or it can have pins that engage with existing holes in the workpiece to position the base part at the desired location. The template can be moved relative to the base part and positioned using a scale. The template has openings through which markings can be made on the workpiece or through which drilling can be performed directly. The drill hole pattern can thus be easily transferred to the workpiece in various defined positions.

[0006] To make the jig shown in the printed document more versatile, for example for different fittings that require different drill hole patterns, the template can be provided with various drill hole patterns, each with a different marking. Depending on the application, the desired drill hole pattern can be transferred to the workpiece. Even though the position of the drill hole patterns can be easily and correctly adjusted thanks to the movable jig, there is still a risk of accidentally transferring an incorrect drill hole pattern that is not needed.

[0007] It is therefore an object of the present invention to provide a teaching of the type mentioned at the outset which enables the application of markings of at least two different borehole patterns without the risk of incorrectly marking or applying a borehole that is not assigned to the desired borehole pattern.

[0008] This task is solved by a doctrine with the characteristics of an independent claim. Advantageous embodiments and further developments are the subject of dependent claims.

[0009] An invention of the type mentioned at the outset is characterized in that the base part has at least two marking openings, wherein in at least one relative position of the slider with respect to the base part at least one of the marking openings of the base part is positioned congruently above or below the at least one marking opening of the slider and wherein in at least one further relative position of the slider with respect to the base part that differs from this, the at least one marking opening of the base part is closed by the slider.

[0010] In the invention, the marking openings can be arranged on the base part or the at least one slide such that, depending on their relative position, one or more of the marking openings of the base part are positioned congruently with one of the marking openings of the slide, while other marking openings are not congruent. A bore in the workpiece or a mark on the workpiece can only be made by means of congruent marking openings. This prevents the accidental use of unintended marking openings. The shape of the marking opening does not necessarily have to be circular; geometries other than circular, such as polygons, elongated holes, or other shapes that provide a clear marking option when superimposed with a second marking opening, are also possible on both the base part and the slide.

[0011] In an advantageous embodiment of the jig, the base part and the at least one slide each have a plurality of marking openings, wherein different borehole patterns with congruent marking openings are formed in the at least two different relative positions of the slide with respect to the base part, the number and / or position of which differ. In this way, even complex and highly varied borehole patterns for different configurations or installation situations can be selectively marked or drilled flawlessly using a single jig. The variety of possible borehole patterns can be increased, if necessary, by using two or more slides, which are arranged, for example, one behind the other or offset from each other in the same plane within the base part.

[0012] In an advantageous embodiment of the jig, the base part is elongated and has a recess between two lateral longitudinal guides. The at least one marking opening is preferably located in the area of ​​the recess. More preferably, the slide is also elongated and guided by the longitudinal guides so that it can be slidably arranged within the recess. The jig can thus be manufactured with minimal material and, if necessary, even easily using a 3D printing process. Preferably, the longitudinal guides are undercut, and the slide has profiled longitudinal sides that are at least partially overlapped by the undercut longitudinal guides. This creates a dovetail joint between the base part and the at least one slide. The jig can be easily assembled by clipping the slide into the recess of the base part.

[0013] Preferably, the base part and the at least one slide feature interlocking detent devices that define at least two different relative positions of the slide with respect to the base part as detent positions. This allows the desired bore pattern to be positioned precisely and easily without requiring any measurements from the user. The detent devices can, for example, comprise at least one detent ridge on the base part and at least two detent openings on the slide. Furthermore, a viewing window can be provided on the base part through which a marking describing the detent position and thus the application of the slide is visible.

[0014] In a further advantageous embodiment of the teaching, a protruding contact rib is arranged on the base part as a stop. Furthermore, another protruding contact rib can be arranged on the at least one slide as a stop. Preferably, this further protruding contact rib of the slide runs parallel to a displacement direction of the slide relative to the base part, with the protruding contact rib of the base part running perpendicular to the displacement direction. In this way, a stop is formed in two mutually perpendicular spatial directions in a simple manner suitable for 3D printing, with which the teaching can be placed against a corner of the workpiece and thus positioned precisely.

[0015] The additional protruding guide rib can be positioned longitudinally in the center of the slide, with marking openings arranged in two rows, mirrored to the protruding guide rib. In this way, the jig can be used to mark or drill holes in a mirror image on two opposite edges of a workpiece. This requirement frequently arises, particularly in furniture manufacturing.

[0016] Finally, at least one further opening can be formed on the base part, which cannot be covered by the slider. This opening can serve as a universal marking opening, independent of the slider's setting, or it can be used for positioning the gauge. The invention is explained in more detail below with reference to exemplary embodiments and the accompanying figures. The figures show:

[0017] Figure 1 shows a drawer and a drawer front with a jig attached, from two different viewing directions;

[0018] Figure 2 shows detailed representations of the teaching from Figure 1 in four different partial images;

[0019] Figure 3 shows the teaching according to Figure 2 in a first rest position in five different partial images;

[0020] Figures 4-6 illustrate the teaching of Figure 2 in further different rest positions, each in three partial images; and

[0021] Figure 7 shows a second embodiment of a teaching in four different partial images.

[0022] In all figures, identical reference symbols denote identical or equivalent elements. For clarity, not every element in the figures is marked with a reference symbol. Relative terms such as "above," "below," "left," and "right" refer to the representation of the figures.

[0023] Figure 1 shows a drawer 1 in the upper section as an example of a furniture component in a three-dimensional representation. The drawer 1 has a front 2, side walls 3, a back wall 4 and a bottom 5.

[0024] In the lower part of Figure 1, the front 2 of the drawer 1 is shown separately from two different perspectives. On the left, the front 2 is shown from its front side, and on the right, from its back 6. On the back 6 of the front 2, adjacent to a transverse side, are holes 7 that accommodate connecting elements, for example, expansion dowels, to connect the front 2 to one of the side walls 3.

[0025] A gauge 10 is attached to the opposite transverse side of the front 2, with which such bores 7 can be marked or through which such bores 7 can be drilled directly. Figure 2 shows the gauge 10 from Figure 1 separately in four partial images a) to d) in more detail.

[0026] In the illustrated embodiment, the teaching device 10 is composed of two elements: an elongated base part 11 and an equally elongated slide 21. Figure a) shows the teaching device 10 from its rear side in an unassembled state, in which the base part 11 and the slide 21 are shown separately side by side. Figure b) shows an enlarged section of the base part 11. Figure c) shows the teaching device 10 from its rear side in an assembled state, in which the slide 21 is clipped into the base part 11. Finally, Figure d) shows the assembled teaching device 10 from its front side.

[0027] The base part 11 has a plurality of marking openings 12. The marking openings 12 are arranged in two rows, with these two rows running parallel to the longitudinal edges of the base part 11. In both rows, the individual marking openings 12 are located in the same longitudinal position; they are thus arranged on the base part 11 in a mirror image with respect to a perpendicular plane of the base part 11. The reason for this lies in the fact that the teaching 10 can also be used in a mirror image. In alternative embodiments, it is also conceivable that the marking openings 12 are positioned differently on both sides for two different applications.

[0028] Additionally, locking tabs 13 are formed at various positions on the base part 11 in both rows of marking openings 12. Furthermore, a viewing window 14 in the form of a larger rectangular opening is provided at one location, and in this embodiment only within one of the rows of marking openings 12.

[0029] A raised rim around the base part 11 forms lateral longitudinal guides 16 parallel to the rows of marking openings 12 on each longitudinal side of the base part 11. The area enclosed by the raised rim, containing the marking openings 12, the locking tabs 13, and the viewing window 14, forms a corresponding recess 17. A first contact rib 15, projecting upwards, is formed on one transverse side of the base part 11, allowing the base part 11 to be positioned against a workpiece, particularly a furniture component such as the front 2 shown in Figure 1. The slider 21 also has a plurality of marking openings 22, arranged in two rows, just as on the base part 11. Furthermore, there are locking openings 23 corresponding to the locking tabs 13, as well as markings 24 visible through the viewing window 14.In the example shown, the markings 24 penetrate the slide 21 so that they are visible as a mirror image from the rear. Finally, an elongated rib is arranged in the center of the slide 21, forming a second mounting rib 25.

[0030] In the assembled state of the gauge, the slide 21 is clipped into the recess 17 of the base part 11. For this purpose, the longitudinal guides 16 of the base part 11 are undercut on their inner side, and correspondingly, the longitudinal sides 26 are profiled, for example, with a chamfer. In partial image c), the gauge 10 is shown in this assembled state from its rear side, and in partial image d), from its front side.

[0031] When used, the gauge 10 is placed with its back side facing the workpiece. As can be seen in Figure 1, the first contact rib 15 of the gauge 10 is positioned against a side edge of the workpiece, for example, the front 2, and the second contact rib 25 is positioned against a perpendicular edge. These two contact ribs 15 and 25 define the position of the base part 11 at the edge of the front 2. The gauge 10, which is symmetrical with respect to the second contact rib 25, allows it to be positioned against either the left or right transverse side of the front 2 in order to create or mark the bores 7 on both transverse sides in a mirror image.

[0032] A special feature of the invention 10 is that both elements that can be moved relative to each other, the base part 11 and the slider 21, are provided with the marking openings 12, 22. When using the invention

[0033] 10. The slider 21 can be moved into different detent positions relative to the base part.

[0034] 11, whereby these detent positions are defined by the arrangement of the detent bars 13 and the corresponding detent openings 23. The user can recognize which detent position is set through the viewing window 14, since the corresponding different marking 24 appears in the viewing window 14 for different detent positions.

[0035] The marking openings 12 and 22 are arranged on the base part 11 and the slide 21, respectively, such that, depending on the detent position, some of the marking openings 12 are congruent with one of the marking openings 22, while others of the marking openings 12 and 22 are not congruent. Only when one of the marking openings 12 is positioned congruently with one of the marking openings 22 can a mark be made on the workpiece or a hole be drilled directly into the workpiece by the gauge 10.

[0036] The marking openings 12 and 22 are now arranged such that, in a detent position, marking openings 12 and 22 only align perfectly at the required locations, thus enabling marking. Conversely, borehole positions that do not belong to the desired borehole pattern but may be assigned to a different detent position are concealed and cannot be used for marking or drilling. This prevents the use of a borehole position not assigned to a detent position.

[0037] The teaching 10 according to Figure 2 is shown below in Figures 3-6 in the four possible different detent positions shown in this application example, in different partial images, in order to explain the function in more detail. The teaching 10 according to the invention is not limited to the use of exactly four different detent positions.

[0038] Figure 3 shows, in partial image a), the assembled gauge 10 in a top view of its rear side. The gauge 10 is set in a first detent position, meaning the slide 21 is in one of four possible detent positions relative to the base part 11. In the position shown, the slide 21 is moved fully to the left within the base part 11. Accordingly, the detent lugs 13 of the base part 11 are engaged in the rightmost of the detent openings 23 of the slide 21. The remaining detent openings 23 are visible to the left of these. In the locked position, the detent lugs 13 are also visible in the two rightmost detent openings 23, as indicated by the reference numerals "13, 23" in the figures.

[0039] Of the majority of the marking openings 22 in the slide 21, four of the marking openings 22 are congruent with underlying marking openings 12 of the base part 11 in this detent position. When using the gauge 10, markings can only be made or drilled through these four congruent marking openings 12, 22. The four accessible marking openings are identified by the reference numerals "12, 22" in this and the subsequent figures and additionally by drawn centering lines.

[0040] In partial image a'), the gauge 10 is shown in a side view, and in partial image b) in a top view. The usable marking openings 12, 22, which are congruent, are also highlighted in the top view. When the gauge is in use, further marking openings 12 in the base part 11 are visible, but cannot be used because they are covered from below by the slide 21. In the top view of partial image b), the marking 24, here "101", which corresponds to the current detent position, can also be seen through the viewing window 14. The marking 24 indicates a specific dimension or product for which the selected setting is suitable.

[0041] In partial image c), a section through the gauge 10 along the section line shown in partial image b) is depicted. Partial image c') shows an enlargement of this section from the area of ​​the congruent marking openings 12, 22. This enlargement clearly shows how the remaining marking openings 12 or 22 are closed by the respective other part, i.e., either the base part 11 or the slide 21, and thus cannot be accidentally used for marking.

[0042] In Figures 4-6, the teaching 10 is shown in a different possible detent position, similar to Figure 3 for sub-images a), b), and c). The figures show that, in the teaching 10 according to the invention, different borehole patterns can be set in the various detent positions, differing in the number of usable marking openings and / or their position. It is also possible for one and the same congruent marking opening 12, 22 to be accessible in several of the detent positions.

[0043] Figure 7 shows in four partial images a) - d) a further embodiment of a teaching 10 according to the invention in the same way as Figure 2. In terms of its basic structure, this teaching 10 corresponds to that shown in the first embodiment, to whose description explicit reference is hereby made.

[0044] In contrast to the embodiment shown in Figures 1-6, different bore patterns can be set in the teaching 10 of Figure 7. Another difference is that the viewing window 14 extends over almost the entire width of the slide 21, thus providing more space for the marking 24.

[0045] Another difference lies in the fact that the base part 11 has two additional openings 18 in its edge region, through which a marking can be made. These additional openings 18 are located outside the area covered by the slide 21. Therefore, these additional openings 18 are always available, regardless of the detent position of the slide 21. The additional openings 18 can be used for marking purposes, but also as positioning aids. For example, a raised area, recess, or other marking can be made on the workpiece to be marked or drilled, which must be congruent with the additional opening 18 when the gauge 10 is correctly positioned. This prevents the gauge 10 from being placed on the wrong side or edge of the workpiece to be marked.
