Description

TECHNICAL FIELD

[0001] The utility model relates to a hinge drill jig for producing a drilling pattern for hinges in furniture plates, comprising

[0002] at least one base body,

[0003] at least one center drill for producing a cylindrical recess for accommodating a hinge cup in a furniture plate,

[0004] at least two clamping devices spaced apart from each other for clamping a furniture plate relative to the base body,

[0005] at least one stop device for abutting the base body against an end side of the furniture plate. BACKGROUND

[0006] This hinge drill jig has been marketed by the applicant for years under the name "ECO DRILL". Here, a simple and portable hand-held device is involved for precisely drilling holes in furniture parts. Here, a specific hinge drilling pattern can be set, so that the center drill can be drilled into the furniture piece at the predefined positions by means of the hand-held drill in order to produce cylindrical holes for accommodating hinge cups. In addition to the central center drill, two lateral pin drills are additionally provided, which have a smaller diameter than the center drill and are used to produce further cylindrical holes for accommodating expandable fixing pins of furniture hinges.

[0007] The disadvantage of the known construction is that, in order to clamp the furniture plate, the two clamping devices have to be manipulated separately from each other. Here, the problem can arise that the two clamping devices are not uniformly adjusted, so that different clamping forces are exerted on the furniture plate by the two clamping devices. This can lead to a relative movement of the furniture plate relative to the base body of the hinge drill jig during the drilling process and ultimately to the drilling of holes in the wrong position. Furthermore, two separate stop pieces are provided for abutting against the end side of the furniture plate, by means of which the distance of the center drill relative to the end side of the furniture plate can be adjusted. The problem can also arise here that the two stop pieces are adjusted differently due to negligence or lack of knowledge, so that in this case there is also a risk of incorrect drilling. This incorrect drilling can ultimately lead to the fact that furniture plates, which usually have a high value and an expensive decorative covering, can no longer be used and are discarded. SUMMARY

[0008] It is the task of the utility model to propose a hinge drill jig of the type mentioned at the outset without the above-mentioned disadvantages.

[0009] According to the utility model, this is achieved by the features of the utility model. Further advantageous embodiments of the utility model are defined in the embodiments.

[0010] According to the utility model, setting up the tensioning rod, through the tensioning rod, at least two clamping devices can be commonly controlled, and / or wherein, at least one stop device is arranged between at least two clamping devices in the central region of at least one base body.

[0011] In other words, setting up the tensioning rod, through the tensioning rod, at least two clamping devices spaced apart from each other can be moved between the tensioning position and the loosening position simultaneously for clamping furniture board. Therefore, different adjustment and / or error operation of the clamping device can be prevented.

[0012] Alternatively or additionally, at least one stop device is arranged between two clamping devices in the central region of the base body. By this measure, different adjustment of two different stop pieces can also be prevented.

[0013] The stop device can have a movable, preferably linearly movable and / or steplessly adjustable stop plate for abutting against the furniture board, for example.

[0014] In order to adjust the position of the stop plate, a rotatable adjustment wheel can be provided, wherein the position of the stop plate relative to the base body can be adjusted by rotation of the adjustment wheel.

[0015] Instead of the rotatable adjustment wheel, the stop plate can also be moved by at least one slot, wherein the pre-adjusted position of the stop plate can be fixed by a locking screw. BRIEF DESCRIPTION OF DRAWINGS

[0025] Figure 1a A piece of furniture 1 is shown, which has a furniture body 2 and a furniture part 3 in the form of a furniture panel 3a, which is movably supported relative to the furniture body 2. The movable furniture part 3 is pivotably supported relative to the furniture body 2 by two or more hinges 4.

[0026] The hinges 4 each have a hinge arm 5 to be fixed at the furniture body 2 and a hinge cup 6 to be fixed at the movable furniture part 3. The hinge cup 6 is pivotably connected with the hinge arm 5, for example, by means of at least one living link. The hinge cup 6 is fixed at the movable furniture part 3 by means of at least one fixing flange 9.

[0027] Figure 1b The movable furniture part 3 in the form of a furniture panel 3a is shown in a perspective view. In order to fix the hinge cup 6 at the furniture panel 3a, a cylindrical recess 7 is provided, which preferably has a diameter of 35 mm, wherein the hinge cup 6 is at least partially accommodated within the cylindrical recess 7 in the assembled state at the furniture panel 3a.

[0028] In addition to the cylindrical recess 7, two lateral pin bores 8a, 8b are also provided, which are provided for accommodating an expandable pin (not shown) of the hinge 4. Such a pin can be arranged at the underside of the fixing flange 9 of the hinge 4.

[0029] The cylindrical recess 7 for accommodating the hinge cup 6 and the pin bores 8a, 8b for accommodating the pin of the hinge 4 are each arranged at a predetermined spacing relative to the end side 19a of the furniture panel 3a and relative to the side faces 19b, 19c.

[0030] However, the two lateral pin bores 8a, 8b are not absolutely necessary, since the fixing flange 9 of the hinge 4 can also be fixed at the furniture panel 3a by means of conventional threaded fasteners.

[0031] The cylindrical recesses 7 for accommodating the hinge cup 6 and the pin bores 8a, 8b for accommodating the pins of the hinge 4 can be produced by means of a hinge drill jig 10 (not shown) Figure 2a ) which is used to produce the drill hole pattern for the hinge 4 in the furniture plate 3a.

[0032] Figure 2a A possible embodiment of the hinge drill jig 10 is shown in perspective view.

[0033] The hinge drill jig 10 comprises:

[0034] at least one base body 11,

[0035] at least one crown drill 12 for producing the cylindrical recesses 7 for accommodating the hinge cup 6 in the furniture plate 3a,

[0036] at least two clamping devices 16a, 16b which are spaced apart from one another and which are used to clamp the furniture plate 3a relative to the base body 11,

[0037] at least one stop device 28 Figure 2b for abutting the base body 11 against the end side 19a Figure 1b of the furniture plate 3a,

[0038] a tensioning lever 15 by means of which the at least two clamping devices 16a, 16b can be jointly actuated, and / or wherein the at least one stop device 28 is arranged between the at least two clamping devices 16a, 16b in a central region of the at least one base body 11.

[0039] The two clamping devices 16a, 16b are jointly movably supported by means of the tensioning lever 15 between a tensioned position and a released position, wherein an incorrect actuation of the clamping devices 16a, 16b can be avoided.

[0040] The clamping devices 16a, 16b can each have a preferably rotatably supported fixing element 17a, 17b by means of which the furniture plate 3a can be pre-clamped relative to the base body 11.

[0041] In order to finally fix the furniture plate 3a relative to the base body 11, a movable, preferably pivotable, tensioning lever 15 is provided, wherein by actuating the tensioning lever 15 a substantially uniform clamping force can be applied to the furniture plate 3a via the clamping devices 16a, 16b.

[0042] The crown drill 12 can be rotated by means of a rotary drive 18a, wherein the crown drill 12 can be driven by rotating this rotary drive 18a by means of a handheld drill 31 Figure 4a 、 Figure 4b .

[0043] In addition to the center bit 12, two further pin drill bits 20 are provided, which are provided for drilling the two pin boreholes 8a, 8b Figure 1b ). The pin boreholes 8a, 8b are provided for accommodating the pins of the hinge 4.

[0044] However, as already mentioned, the manufacture of the pin boreholes 8a, 8b can be dispensed with, since it is also possible to provide threaded fasteners for fixing the fixing flanges 9 of the hinge 4.

[0045] The two pin drill bits 20 likewise each have a rotary drive 18b, 18c, wherein the pin drill bits 20 can be brought into a rotary state by driving the rotary drives 18b, 18c by means of the hand drill 31.

[0046] Conversely, if instead of the two pin boreholes 8a, 8b only recesses in the form of markings are manufactured in the furniture plate 3a for accommodating the threaded fasteners, then additional elements in the form of spacers (not visible here) are provided. The spacers, which are preferably configured as C-clamps, can be inserted onto the stem below the rotary drives 18b, 18c. In this way, the rotary drives 18b, 18c can only move in the direction of the base body 11 on a small partial area when driven with the hand drill 31, so that essentially only the centering tips of the pin drill bits 20 can be sunk into the furniture plate 3a in order to manufacture the markings.

[0047] The tensioning lever 15 is movably supported between a tensioning position and a release position. In the Figure 2a tensioning position of the tensioning lever 15 is shown, in which at least one rotary drive 18a, 18b, 18c, preferably all the rotary drives 18a, 18b, 18c provided, of the hinge drill jig 10 can be accessed.

[0048] Conversely, if the tensioning lever 15 is in the release position, then access to one rotary drive 18a, 18b, 18c, preferably to all the rotary drives 18a, 18b, 18c, is prevented. This constitutes a significant safety aspect, since the rotary drives 18a, 18b, 18c can only be accessible by means of the hand drill 31 when the furniture plate 3a is fixed in accordance with the regulations with respect to the base body 11 of the hinge drill jig 10.

[0049] At least one stop 21a is provided, which is movably, preferably pivotably, supported at the hinge drill jig 10 and / or has at least one scale 22a for displaying the spacing of the center bit 12 with respect to the side face 19b, 19c Figure 1b ) of the furniture plate 3a. The position of the stop 21a along the scale 22a can be determined by means of a clamping screw 26a.

[0050] The chip material can be sucked through the at least one suction opening 27. It is preferably provided that the at least one suction opening 27 extends obliquely in the direction of the crown drill 12 and / or has at least one O-ring for clamping a suction sleeve.

[0051] Figure 2b A top view of the hinge drill jig 10 is shown, in which the pivotable tensioning lever 15 is in the loosened position. In the loosened position of the tensioning lever 15, the rotary drive 18a, 18b, 18c cannot be manipulated by the hand drill 31, since the tensioning lever 15 blocks access to the rotary drive 18a, 18b, 18c.

[0052] The hinge drill jig 10 can have at least one handle 23, preferably in the form of an arc of a U, for operating or for transporting the hinge drill jig 10.

[0053] The at least one stop device 28 for abutting the base body 11 against the end side 19a of the furniture board 3a Figure 1b ) is arranged between the at least two clamping devices 16a, 16b in the central region of the at least one base body 11.

[0054] The stop device 28 can have a movable, preferably linearly movable and / or steplessly adjustable stop plate 28a for abutting against the furniture board 3a.

[0055] In the shown embodiment, the position of the stop plate 28a can be adjusted by means of at least one slot 28b and / or can be fixed after the adjustment has been completed by means of a rotatably supported knurled screw 28c.

[0056] Of course, other possibilities can also be provided for the stepless adjustment of the stop plate 28a, such as at least one adjustment wheel configured as a self-locking, an eccentric wheel configured as a self-locking or a self-locking worm gear.

[0057] The stop device 28 can have at least one window 24, which enables a view through to a marking 25 arranged or arrangeable at the furniture board 3a. The window 24 is configured relatively large, so that a significant readability of the marking 25 is provided.

[0058] Figure 3a A front view of the hinge drill jig 10 is shown, in which the crown drill 12, the chip breaker 14 and the two lateral pin drill bits 20 are shown.

[0059] It can be seen that the at least one crown drill 12 is offset in the height direction from the at least one pin drill bit 20, preferably from the two pin drill bits 20, by an amount X, preferably by about 3 mm.

[0060] By offsetting the column top drill bit 12 with the lateral pin drill bit 20, the risk of longer cutting material getting stuck is reduced, and thus scratches on the decorative surface of the furniture panel 3a are reduced.

[0061] The column drill bit 12 and the pin drill bit 20 can be driven separately from each other by rotary drive devices 18a, 18b, and 18c. To drive the rotary drive devices 18a, 18b, and 18c, a handheld drill 31 and a screwdriver head 30 that can engage with the rotary drive devices 18a, 18b, and 18c are required. Figure 4a , 4b The screwdriver head 30 can be configured as a Phillips head, a star head, or a Torx head.

[0062] Figure 3b The hinged drill jig 10 is shown in the top view, in which the furniture panel 3a is clamped and secured by a pivot rod 15. The pivot rod 15 is thus in a tensioned position, in which the rotary drive units 18a, 18b, and 18c can be accessed using a handheld drill 31. Conversely, in the relaxed position of the tension rod 15, access to the rotary drive units 18a, 18b, and 18c is prevented.

[0063] Hinge drill jig 10 in addition to Figure 2a In addition to the stop 21a shown, there is at least one additional stop 21b, wherein the stop 21a is configured to abut against the first side 19b of the furniture panel 3a. Figure 1b At the location ), and another stop 21b is provided for abutting against the second side 19c of the furniture panel 3a.

[0064] The additional stop 21b can be fixed by the locking screw 26b along the position of the scale 22b.

[0065] When not in use, the two stops 21a and 21b can be flipped into the base 11 of the hinge drill jig 10.

[0066] The distance between the column top drill bit 12 and the end side 19a of the furniture board 3a can be adjusted by the stop device 28. The stop device 28 includes a linearly movable and / or steplessly adjustable stop plate 28a, which is configured to abut against the end side 19a of the furniture board 3a.

[0067] To adjust the stop plate 28a, loosen the knurled screw 28c and move the stop plate 28a to the desired position through at least one elongated hole 28b. The pre-adjusted position of the stop plate 28a can then be secured again by the knurled screw 28c.

[0068] In order to read off the position of the stop device 28, at least two scales 29a, 29b are provided, wherein a first scale 29a of the two scales shows the distance from the center of the cylindrical recess 7 to be produced and a second scale 29b of the two scales shows the distance from the edge of the cylindrical recess 7 to be produced.

[0069] The advantage of providing two scales 29a, 29b is that in combination with a Korpuskonfigurator or product catalog for the drilling of the cylindrical recess 7, there are two different size specifications which can be displayed by the two scales 29a, 29b. Of course, only one of the two scales 29a, 29b can be provided.

[0070] According to an embodiment, it can be provided that the at least one base body 11 has at least one accommodation field 50 for accommodating a drill template 51 for a hinge arm 5 of a hinge 4, which is preferably configured as a fitting angle.

[0071] In order to releasably secure the drill template 51 in the accommodation field 50, at least one magnet 52 can be used. The drill template 51, which is configured as an additional part, is configured for producing a drilling pattern for a hinge arm 5 at the furniture panel 2.

[0072] Figure 4a A hinge drill 10 is shown, which has a base body 11, a handle 23 arranged at the base body 11 and a tensioning lever 15 which is pivotable relative to the base body 11.

[0073] In Figure 4a , the tensioning lever 15 is in a release position in which the tensioning lever 15 at least partially covers the rotary drive 18a of the center drill 12 and thus prevents access to the rotary drive 18a. In Figure 4a , it is thus not possible to actuate the rotary drive 18a by means of the screwdriver head 30 of the hand drill 31.

[0074] In contrast, in Figure 4b , the tensioning lever 15 is in a tensioning position in which the rotary drive 18a of the center drill 12 is freely accessible to the screwdriver head 30 of the hand drill 31. In the tensioning position of the tensioning lever 15, the cylindrical recess 7 in the furniture panel 3a can thus be drilled at a predefined position by driving the rotary drive 18a by means of the hand drill 31.

[0075] Figure 5a A partially sectioned view of the hinge drill 10 is shown, in which the tensioning lever 15 is in the release position. The tensioning devices 16a, 16b each have a shaft 33 which is guided in a long hole 32 in a play.

[0076] The tensioning lever 15 is surrounded by a rotary axis 37 (Figure 6a It is rotatably supported at the base 11 and / or has at least one eccentric surface 34 arranged at the tensioning rod 15, the eccentric surface being used to move at least two clamping devices 16a, 16b relative to the base 11.

[0077] The rotation axis 37 of the tensioning rod 15 is substantially the same as the rotation axis 39 of the drill bit 12. Figures 7a to 7c It extends at right angles.

[0078] Shaft 33 and clamp 35 ( Figure 6a , Figure 6b The clamp is configured to rest against the bottom side 19d of the furniture board 3a. Figure 6a , Figure 6b ) place.

[0079] At least one clamping device 16a, 16b, preferably two clamping devices 16a, 16b, has at least one accumulator 38. Figure 6b The accumulator applies force to the clamping hoop 35 at the position where the furniture board 3a is pre-clamped.

[0080] The pre-clamped position of the shaft 33 connected to the clamp 35 can be fixed by rotatable fixing elements 17a and 17b.

[0081] However, the pre-clamping position is secured only once by the fixing elements 17a and 17b. Once the pre-clamping position is adjusted relative to the material thickness of the furniture board 3a, the clamping and loosening of the furniture board 3a are achieved solely by manipulating the tension rod 15.

[0082] Figure 5b A partially cut-away view of the hinge drill jig 10 is shown, in which the tension rod 15 is in the tensioned position.

[0083] Shaft 33 can be pivoted from the tension rod 15 according to... Figure 5a Starting from the released position and moving to according to Figure 5b In the tensioned position, the shaft 33 is located at the end of the elongated hole 32, and the tensioned position of the tensioning rod 15 is fixed by the eccentric surface 34.

[0084] Figure 6a A cross-section of the hinged drill jig 10 is shown, in which the tension rod 15 is in the released position, in which the rotary drive 18a of the top drill bit 12 cannot be accessed by the handheld drill 31 for operation.

[0085] The clamping devices 16a and 16b have at least one clamp 35 for abutting against the bottom side 19d of the furniture board 3a. This is achieved through at least one accumulator 38. Figure 6b) the clamp 35 is loaded with force in the direction of the position in which the furniture plate 3a is pre-clamped. The at least one energy accumulator 38 can be configured, for example, as a tension spring or a pressure spring.

[0086] By exerting force on the handle 36 against the force of the force accumulator 38, the pre-clamped position of the clamp 35 can be released.

[0087] In the embodiment shown, the pre-clamped position of the clamp 35 is releasable in such a way that the handle 36 is pushed in a downwardly directed direction, i.e. in a direction extending parallel to the rotation axis 39 of the spade drill 12. In this way, the clamp 35 is moved downwardly, so that the furniture plate 3a and the hinge drill jig 10 can be oriented relative to one another or moved apart from one another.

[0088] If the furniture plate 3a is finally correctly oriented relative to the hinge drill jig 10, the pre-clamped position of the furniture plate 3a can be pre-fixed by the clamping elements 17a, 17b of the clamping devices 16a, 16b.

[0089] The at least one spade drill 12 has a distance of more than 3 mm from a zero plane in the zero position, in which the untreated surface 19e of the furniture plate 3a can be arranged. In this way, the risk of long chip material jamming is reduced.

[0090] Figure 6b A side view of the hinge drill jig 10 is shown, in which the tensioning lever 15 is in a tensioned position, in which the rotation drive 18a of the spade drill 12 can be accessed.

[0091] By means of the tensioning lever 15, which can be pivoted about the rotation axis 37 Figure 6a ) the pre-clamped position can be finally fixed, so that the cylindrical recess 7 can be drilled by driving the rotation drive 18a by means of the hand drill 31.

[0092] The force accumulator 38 is shown schematically, which loads the clamp 35 with force in the direction of the position in which the furniture plate 3a is pre-clamped.

[0093] Figures 7a to 7c Different views of the spade drill 12 for the hinge drill jig 10 for producing a drill hole pattern for a hinge 4 in a furniture plate 3a are shown.

[0094] Figure 7a A view of the spade drill 12 and the chip breaker 14 arranged or arrangeable at the spade drill 12 is shown.

[0095] The spade drill 12 comprises:

[0096] - at least one lever 40, which can be rotated about a rotation axis 39, for clamping the spade drill 12 into the hinge drill jig 10,

[0097] - at least one cutting head 41 having at least one end-side main edge 13 for producing a cylindrical recess 7 in the furniture board 3a,

[0098] - at least one chip breaker 14 for comminuting the produced chip material, wherein the at least one chip breaker 14 is at least partially conically configured in order to push the chip material to be comminuted obliquely outwardly from the axis of rotation 39 towards a direction pointing away from the axis of rotation 39.

[0099] The conical or frustoconical shape of the chip breaker 14 is configured for obliquely outwardly transporting the produced chip material from the axis of rotation 39 during the drilling of the cylindrical recess 7, wherein the pushed chip material can be comminuted by the plurality of cutting edges 43 of the rotating chip breaker 14.

[0100] According to an embodiment, the at least one chip breaker 14 is essentially crown-shaped configured.

[0101] The at least one chip breaker 14 can have at least one, preferably circular, opening 44 for accommodating the shaft 40.

[0102] According to an embodiment, the at least one chip breaker 14 is configured as a component separate from the crown drill 12, which is fixedly connected, preferably glued, welded or crimped, to the crown drill 12.

[0103] Alternatively, the chip breaker 14 and the crown drill 12 can be releasably connected to each other by at least one form-fit connection. In the connected state, the chip breaker 14 is connected to the crown drill 12 in a torsion-proof manner by the form-fit connection. In the event of possible damage or wear, the chip breaker 14 can be easily replaced.

[0104] Alternatively, it is possible that the at least one chip breaker 14 is configured in one piece together with the crown drill 12.

[0105] The at least one chip breaker 14 can have at least one, preferably dimple-shaped and / or conically constricted, discharge channel 45 for discharging chip material.

[0106] Preferably, a plurality of, preferably dimple-shaped and / or conically constricted, discharge channels 45 are provided for discharging chip material.

[0107] In the shown embodiment, the discharge channels 45 are essentially semi-elliptically configured in a top view and / or are uniformly distributed on the conical or frustoconical peripheral surface of the at least one chip breaker 14.

[0108] Between two adjacent discharge channels 45, at least one cutting surface 43 for comminuting chip material can be arranged.

[0109] In the embodiment shown, the at least one chip breaker 14 has twelve discharge channels 45 and / or twelve cutting faces 43.

[0110] According to one possible embodiment, the discharge channels 45 can taper conically, preferably in an angular range of between 20° and 30°.

[0111] The crown drill 12 can have at least one, preferably lateral and / or web-shaped, cutting face 46 for crushing the chip material, and / or at least one centering tip 42 for centering the crown drill 12 at the furniture board 3a.

[0112] The longitudinal direction of the cutting face 46 can extend substantially parallel to the rotational axis 39 of the crown drill 12.

[0113] In the embodiment shown, the crown drill 12 has, in addition to the at least one main blade 13, at least one further, preferably pointed, end-side blade 47.

[0114] Figure 7b A chip breaker 14 arranged at the crown drill 12 is shown, wherein the chip breaker 14 is arranged behind the cutting head 41 in the feed direction of the crown drill 12.

[0115] Figure 7c A chip breaker 14 arranged at the crown drill 12 is shown in cross section.

[0116] According to one preferred embodiment, the maximum diameter of the at least one chip breaker 14 is designed to be smaller than the minimum diameter of the at least one cutting head 41. In this way, the removal of material of the furniture board 3a is ensured to take place preferably exclusively by the cutting head 41 and not by the chip breaker 14.

[0117] The conical or truncated conical chip breaker 14 has two differently sized base surfaces which are spaced apart from one another along the rotational axis 39, wherein the larger base surface of the chip breaker 14 has a greater spacing from the cutting head 41 than the smaller base surface.
