Description

[0001] The present invention relates to a device for transferring at least one marking, in particular a drill marking, between opposing surfaces of a workpiece, comprising a first transfer unit and at least one second transfer unit corresponding to the first transfer unit.

[0002] When processing workpieces, especially wooden panels, boards, or door leaves, markings often need to be made, for example, to prepare for drilling or for mounting fittings such as hinges, hooks, or brackets. In many cases, it is necessary to place such markings on opposite surfaces of a workpiece, with the markings corresponding precisely to each other, especially at the same height or in the same position.

[0003] In practice, markings are often applied manually by measuring and transferring them using a tape measure, ruler, square, or stop. However, this method is prone to discrepancies, such as reading errors, tolerance accumulation, inaccurate reference edges, or a change in the reference position when turning or repositioning the workpiece. Especially with multiple markings, for example, in a hole pattern, even a slight misalignment can prevent drill holes from being aligned or fittings from being mounted correctly. Furthermore, manual measuring is time-consuming and error-prone.

[0004] Against this background, there is a need to transfer markings between opposing surfaces of a workpiece more easily and reliably, in particular so that corresponding markings can be created on both sides of the workpiece in the same position without time-consuming manual measuring.

[0005] The object of the present invention is to solve problems known from the prior art, in particular to apply markings to opposite surfaces of a workpiece with increased accuracy and reproducibility.

[0006] The problem is solved by a device with the features of the independent claim. Advantageous or preferred embodiments are each the subject of a corresponding dependent claim.

[0007] A device is proposed for transferring at least one marking, in particular a drill mark, between opposing surfaces of a workpiece, comprising a first transfer unit and at least one second transfer unit corresponding to the first. For the purposes of this disclosure, a marking is understood to be a designation created on a surface of the workpiece that serves to define a machining position, for example, for subsequent machining. A drill mark is a marking that indicates, in particular, a drilling position and / or a drill bit position, for example, in the form of a dot, a center mark, a marking hole, or a marked contour.

[0008] A workpiece is, in particular, a component on which a marking is to be transferred from a first surface to an opposing second surface. The workpiece can, for example, be designed as a plate-shaped or door-shaped element, especially as a wooden panel, wooden door, or similar workpiece; however, the workpiece can also be made of other materials and / or have other geometries.

[0009] A transfer unit is a device component designed for the precise positioning and / or guidance of a marking on the respective surface of the workpiece. The transfer unit can be designed, in particular, as a template element, for example, as a plate, strip, frame, support body, or insert carrier. The transfer unit can be made of plastic and / or metal, in particular from an injection-molded plastic, a milled or stamped metal part, or from a combination of materials, for example, a plastic body with embedded metal parts or vice versa.

[0010] The transmission units each comprise at least one marking area for applying the marking and at least one coupling device for aligning the transmission units relative to each other.

[0011] A marking area is a functional area provided on the respective transmission unit that enables and / or supports the application of a mark to the surface of the workpiece. For this purpose, the marking area can, for example, provide a defined position, contact geometry, and / or guidance for a marking device, but is not limited to these features.

[0012] A coupling device is a device provided on at least one of the transmission units by means of which the transmission units can be brought into a predetermined relative position and / or held in this relative position in order to enable a corresponding positioning of the transmission units on opposite surfaces of the workpiece.

[0013] The relative alignment of the transmission units to each other enables a simple and reproducible transfer of the marking between the opposing surfaces of the workpiece, thereby reducing the alignment effort and supporting a high positional accuracy of the transferred marking.

[0014] It is advantageous if the at least one coupling device comprises at least one coupling element, in particular a plurality of coupling elements.

[0015] Preferably, several coupling elements are provided, in particular four coupling elements, which are preferably arranged in edge regions of the respective transmission unit, especially such that one coupling element is assigned to each corner region. This allows a defined relative position of the transmission units to be stabilized in two directions and reduces tilting. However, the device is not limited to a specific number or arrangement of the coupling elements.

[0016] The use of multiple coupling elements, in particular a four-element arrangement in corner areas, supports a particularly stable and precise relative positioning of the transmission units, thereby improving the accuracy of the transmitted marking and reducing operator errors, especially due to misalignment or offset.

[0017] In an advantageous embodiment of the invention, the at least one coupling element is designed as a magnetic coupling element for aligning the transmission units relative to each other through the workpiece.

[0018] A magnetic coupling element is a coupling element that provides a magnetic coupling effect by means of which the first transmission unit and the second transmission unit can be aligned relative to each other and / or positioned relative to opposite surfaces of the workpiece. The magnetic coupling effect is designed such that it preferably acts through the workpiece, so that the transmission units automatically assume a corresponding relative position relative to each other and / or can be held in this position, even with workpiece material in between.

[0019] The magnetic coupling element can comprise a permanent magnet and / or be designed as an electromagnet. In a permanent magnet configuration, the magnetic coupling can be provided without an external power supply. In an electromagnet configuration, the magnetic coupling effect can be switched and / or its strength can be adjusted, for example, for targeted activation / deactivation or to adapt to different workpiece thicknesses and / or materials.

[0020] Furthermore, it is advantageous if several magnetic coupling elements are arranged with polarity coding, in particular such that adjacent magnetic coupling elements have alternating pole orientations. This facilitates a clear assignment of the relative position of the transmission units and reduces or prevents unwanted rotation of the transmission units relative to each other.

[0021] The magnetic design of the coupling elements enables particularly simple, fast, and automatic relative alignment of the transmission units, without requiring any penetration or mechanical insertion through the workpiece. Furthermore, a polarity-coded, especially alternating, arrangement of several magnetic coupling elements increases rotational stability and thus further improves the positional accuracy of the transmitted marking.

[0022] It is advantageous if at least one transmission unit includes at least one replaceable insert element.

[0023] An interchangeable insert element is a component detachably mounted on a transmission unit. In its assembled state, it provides and / or influences the functional geometry of the transmission unit and can be easily removed from the transmission unit and replaced with a different insert element. This allows for the use of different insert elements that may differ, for example, in their marking geometry, dimensions, arrangement of marking areas, and / or associated function, without requiring the entire transmission unit to be replaced.

[0024] It is advantageous if both the first and second transmission units each have an insert element that is designed to correspond to each other, so that if a specific insert element is used in the first transmission unit, a matching insert element can be used in the second transmission unit. In this way, the transferability of the marking between the opposing surfaces is supported, and the adaptability of the device to different applications is improved while maintaining high positional accuracy.

[0025] According to an advantageous embodiment of the invention, the at least one marking area is arranged on the at least one insert element.

[0026] By positioning the marking area on the insert element, the marking function can be adapted to different applications in a particularly simple way, simply by replacing the insert element. This allows the device to be flexibly configured for different marking positions and / or marking geometries without having to change the transmission unit itself, thus reducing the changeover effort.

[0027] Furthermore, it is advantageous if the at least one marking area comprises at least one marking opening, in particular a plurality of marking openings. Additionally or alternatively, it is advantageous if the at least one marking area comprises a marking contour.

[0028] The marking area can, for example, have a single marking opening to indicate the position of a drill bit. Alternatively or additionally, multiple marking openings can be provided, such as a hole pattern for transferring the position of several holes, for example, for mounting a hinge, hook, bracket, or similar fitting. Additionally or alternatively, the marking area can be designed as a marking contour, for example, as an outline-like contour for marking a recess, a milled groove, or the mounting position of a component.

[0029] At least one marking opening allows for particularly easy, quick, and precise application of a drill mark, especially by inserting a marking pen, center punch, or pencil. Multiple marking openings enable the simultaneous, precisely aligned transfer of several marks, allowing for the reproducible creation of assembly patterns. A marking contour also allows for the transfer of contours and outlines, making the device versatile not only for point markings but also for area or line markings.

[0030] In one example application, an interchangeable insert element has multiple marking openings in the form of a hole pattern, suitable, for instance, for a hinge. First, a primary transfer unit is positioned with the insert element on a primary surface of the workpiece, such as the front of a wooden panel or door leaf, and held in place. The corresponding secondary transfer unit is then positioned on the opposite secondary surface of the workpiece, such as the back. Magnetic coupling elements allow the transfer units to align with each other and hold them in the correct relative position through the workpiece. Drilling marks can then be made on both sides of the workpiece through the marking openings of the two transfer units, ensuring that the marks are aligned at the same height.The position is located on opposite surfaces of the workpiece. This reduces or eliminates the need for prior measuring, scribing, or transferring using separate measuring instruments, thereby improving repeatability and assembly speed.

[0031] Further advantages of the invention are described in the following exemplary embodiments. These show: Fig. 1 a schematic sectional view of a device according to a first embodiment, Fig. 2 a schematic sectional view of a device according to a second embodiment.

[0032] In the following description of the figures, the same reference symbols are used for identical and / or at least comparable features in the different figures. The individual features, their design, and / or mode of action are usually only explained in detail upon their first mention. If individual features are not explained again in detail, their design and / or mode of action corresponds to the design and mode of action of the similarly functioning or identically named features already described with reference to the preceding figures.

[0033] Two exemplary embodiments of a device 1 are explained below with reference to the figures. For the sake of clarity, only one transmission unit 2 of the device 1 is shown in each figure. However, the device 1 comprises a first transmission unit 2 and at least one second transmission unit 2 corresponding to the first transmission unit 2, which cooperate to transmit at least one marking between opposing surfaces of a workpiece.

[0034] Fig. Figure 1 shows a schematic sectional view of a device 1 according to a first embodiment. The device 1 comprises a transmission unit 2, wherein the transmission unit 2 has a marking area 3 for applying a marking. The marking area 3 includes a marking opening 7 through which, for example, a drill mark can be applied to a surface of a workpiece.

[0035] Furthermore, the transmission unit 2 comprises a coupling device 4 for the relative alignment of the transmission unit 2 with a corresponding further transmission unit 2 of the device 1. The coupling device 4 comprises several coupling elements 5, which in the illustrated embodiment are arranged in edge regions of the transmission unit 2, in particular such that one coupling element 5 is assigned to each corner region. This supports a stable and reproducible relative positioning of the transmission units to be coupled, in particular to reduce offset and / or tilting.

[0036] The coupling elements 5 are preferably designed as magnetic coupling elements, so that a coupling effect can be achieved through a workpiece. Alternatively, the coupling elements 5 can also be designed in another way for coupling and relative alignment.

[0037] Fig. Figure 2 shows a schematic sectional view of a device according to a second embodiment. In the second embodiment, the transmission unit 2 has an interchangeable insert element 6. The marking area 3 is arranged on the insert element 6, so that the marking function can be adapted to different applications by replacing the insert element 6.

[0038] In the Fig.In the second embodiment shown in Figure 2, the marking area 3 comprises a plurality of marking openings 7, which are designed as a hole pattern. This allows several drill markings to be applied in a predetermined relative arrangement, for example, for mounting a fitting such as a hinge, a hook, or a bracket. The insert element 6 is received in the transmission unit 2 such that it is held in a defined position. A corresponding insert element 6 is provided for each corresponding transmission unit 2.

[0039] To transfer markings, a first transfer unit 2 is positioned on a first surface of a workpiece and held there, particularly by a user. The corresponding second transfer unit 2 is then positioned on the opposite second surface of the workpiece. Using the coupling device 4, particularly the coupling elements 5, the two transfer units 2 are aligned relative to each other and positioned in a corresponding relative position, preferably automatically through the workpiece. The markings can then be applied to both opposite surfaces through the marking openings 7, ensuring that the markings are present at the same height and / or position on both sides of the workpiece.This reduces or eliminates the need for manual measuring and transferring with separate measuring instruments, thereby improving repeatability and assembly speed in particular.
