Abstract

The jig (15) has a template with an aperture for the milling cutter located at a defined axial dimension to the face of the door leaf and clearance to the door lower edge and/or to other milled holes. Clamps (27) secure the jig to door edge or the frame limb. The position of the milling templates (21) are adjustable on a carrier (16,17) for varying the axial- and/or the clearance dimensions. Two parallel carriers adjustable in position relative to one another can be provided and two pars of clamping jaws the positions of which can be adjusted relative to the template.

Description

The invention relates to a milling jig for milling insert pockets for locks in the edge region of door leaves or recesses of associated striking plates in edge regions of passive leaves or frame legs, with at least one milling template, which has an opening for the milling cutter to pass through, the opening having a defined axial dimension to the door leaf surface and lies at a defined distance from the bottom edge of the door and / or to openings in other cutouts, and with clamping jaws for clamping the milling jig onto the edge area of the door or frame leg.

Milling jigs of the aforementioned type are known. Setting the stop direction DIN right or DIN left requires a number of adjustment steps. Different door and frame profiles also require the use of interchangeable milling templates, which turns out to be expensive to manufacture and store.

The object of the invention is based on the task of designing a milling jig of the type in question in a technically simple manner in such a way that it can be adapted to rebated doors and is suitable for doors hinged on the right as well as on the left.

This technical problem is first and essentially solved in a milling jig with the features of claim 1, the focus being on the milling template being adjustably arranged on a carrier for varying the axis and / or spacing dimension.

As a result of such a configuration, a milling gauge of the type in question of increased utility value is specified. The axis dimension for rebated doors, which corresponds to the distance between the door surface adjacent to the opening leg and the center plane of the lock pocket, is easy to maintain. This is done by merely moving the milling template crosswise relative to the clamping jaws. If the direction of the door stop is to be changed, the milling template must also be adjusted relative to the beam, in the longitudinal direction of the beam. This means that the millings to be produced are incorporated in accordance with the standards. The other millings, as required for locks with multiple locking, are also positioned as intended. The milling jig can also be assigned to the frame legs of fixed frames in order to produce the corresponding cut-outs there, be it for angled striking plates or trough-shaped striking plates. The corresponding milled recesses can also be created in an equivalent manner for inactive leaves.

An advantageous version of the milling jig is characterized by two parallel supports, the distance between which can be adjusted. Along with an adjustment of the parallel beams, their position changes in relation to the milling template, so that the milling jig can be adapted to a wide variety of profiles or thicknesses of the door.

According to the invention it is provided that two clamping jaws are arranged opposite each other in pairs and each clamping jaw can be displaced relative to the milling template in the transverse direction to the beam extension. This is it Optimized clamping of the milling jig on the edge area of the door or frame.

Clamping advantages result from several clamping jaws arranged parallel to each other and adjustable in position by a common adjusting element. By actuating this adjusting element, several clamping jaws are brought into contact with the door leaf surface at the same time.

The adjusting element fulfills a double function in that it forms a common carrier which is adjustable with the clamping jaws. This saves components. Along with this, the milling gauge is relatively light and thus easier to use.

In an advantageous manner, the adjusting member is designed as a drive shaft lying parallel to the beam extension and engages with toothed wheels in a toothing of transverse cross-beams on which the clamping jaws ride. In connection with a rotation of the carrier (s), the distance between the clamping jaws and the milling template or the door leaf surfaces is changed, so that all clamping jaws can be brought into the ready-to-stand position for a short time.

The area of application of the milling jig is increased by two mutually opposite, finely adjustable additional milling templates. In addition to the incorporation of openings forming lock pockets, the transverse openings for the handle mandrel and the lock cylinder can also be produced while observing the desired backset dimensions.

The routing template for the door wing receives its correct alignment through centering projections arranged on the underside of the milling template for insertion in the frame groove of a plastic wing or for cornering on the opening leg of a wooden wing. After this centering has taken place, the clamping jaws are then brought into the contact position with the door leaf surfaces via the supports designed as drive shafts.

An advantageous feature of the invention is then to provide at least one milling template that can be displaced in the direction of extension of the carrier between two fixed end positions relative to the carrier. As already mentioned at the beginning, this shift occurs when the stop direction changes, so that the predetermined distance between the lower edge of the door and the handle height can always be maintained. Accordingly, the lock pocket in the door also receives its intended position.

If more lock pockets are to be provided on the door in order to be able to use a lock with a multi-point lock, which has a main lock and additional locks, additional milling templates that can be moved synchronously with the milling template must be used, the displacement path of the latter being greater than that of the former milling template.

The synchronization is carried out in a simple manner via a lever-push rod gear. Is z. B. relocated one of the other milling templates, then the first-mentioned milling template is moved along via the lever / push rod gear, and in a shorter way due to the corresponding lever ratio.

Due to the measure that the milling templates move together with the clamping jaws, these do not change their clamping position for the milling opening.

Another advantageous feature of the invention can be seen in the fact that the milling template is frame-shaped for the latching insert of exchangeable template inserts. On the one hand, the template inserts remain in their intended position and do not fall out of the frame opening. On the other hand, differently designed template inserts can be used.

Reference edges for maintaining the spacing dimensions are produced by milling templates which are arranged at the end region of the carrier, provided with a stop, and which can be displaced and locked relative to the carrier.

Furthermore, an advantageous feature of the invention is to provide fixed stops adapted to the rebate profiling, which are in opposition to the clamping jaws.

Another version is characterized in that the clamping jaws slidingly guided on cross members can be clamped by clamping handles acting on the cross members. After the clamping jaws have come into contact with the edge of a door, for example, the fixation of the clamping jaws to the crossbeam also causes the clamping jaws to be displaced into the clamping position. There is therefore no need to provide a ratchet ratchet, which is intended to prevent an evasive displacement of the clamping jaws occurring in the clamping position of the clamping jaws. This makes the setup of the milling gauge even easier.

In a favorable manner, the procedure is such that the clamping handles act on the crossmember with a thrust piece to achieve a tilting position of the clamping jaws. The tilt axis forms the carrier itself, so that the clamping jaws come into a fixed contact position after the clamping handles have been brought into effect.

It should also be emphasized that the additional milling templates, which can be adjusted in stages, form a guide rail on which a hole milling jig which can be fixed in different latching positions can be displaced. This measure makes it possible to use a hole milling jig to produce the millings for the locking cylinder and the arbor.

Accurate milling is always achieved according to the invention in that the hole opening of the milling jig is formed by the inner ring of a rolling bearing. On the one hand, the cutter is guided through this, and on the other hand, the hole opening is prevented from being enlarged by the cutter edges.

Different stop directions, the invention is further justified by the fact that the milling template, which can be displaced relative to the carrier, is locked in the predetermined end positions by means of a plug bolt which engages with the carrier. Depending on the stop direction, be it on the left or right, the milling template is brought to the carrier in the corresponding end position, which is then fixed by the socket pin.

It is provided that the milling template can be displaced between two end stops on the carrier side. As soon as the milling template reaches one or the other end stop, the socket pin is in alignment Opposite to an assigned locking hole, so that the milling template can be fixed at short notice. This eliminates the need to search for the locking hole.

The changeover of the milling template to the stop directions is facilitated by stop indicators arranged on the carrier, in each case one being covered in a stop position and the other stepping into a viewing window.

In order to avoid splintering when milling out in wood material when the milling cutter runs out, the fixed stops are made of plastic or the like, at least partially cover the fold area to be provided with milling and are illustrated when milling for the first time.

Finally, an advantageous feature is to provide a clamping jaw that is fixed and movable on the cross member and that the cross member can be displaced and fixed in the transverse direction to the carrier. The bracing is carried out in such a way that by moving the crossbeam and thus the fixed clamping jaw, it arrives in its contact position with the relevant door part. The crossbeam is fixed and then the clamping jaw, which is movably arranged on the crossbeam, is brought into the clamping position. Alternatively, it is also possible to first bring both clamping jaws into the clamping position and then to move the crossbeam and fix it.

A single-leaf door 1 is partially shown in horizontal section in FIG. It is designed as a plastic wing and has a circumferential frame 2 with an impact leg 3 and a frame groove 4 adjacent to this for receiving a faceplate and a drive rod known per se. The area of the frame 2 lying beyond the frame groove 4 merges into a step-shaped shoulder 5. The latter opposes a stop leg 6 of a vertical frame leg 7 of a fixed frame. The frame leg 7 is also designed in two stages. Opposed to the frame groove 4 is a milled recess 8 for receiving an angled locking plate, not shown. Both the recess 8 and the lock pocket (not illustrated) to be manufactured beyond the frame groove 4 are incorporated with the aid of milling gauges. In contrast to the frame 2, the frame leg 7 is made of wood.

FIG. 9 shows a section of a double-leaf door in a horizontal section, consisting of the passive leaf 9 and the swivel leaf 10. Their surrounding frames 11, 12 are made of wood or plastic. With regard to the frames 2, 12, they are made of hollow plastic profiles. The facing fold edges of both frames are designed in two stages. Following the impact leg 3 ', the frame 12 forms the frame groove 4. 8, the impact leg 3 'of the frame 12 acts on the middle step 13 of the passive leaf 9. There is an angular recess 8' for receiving an angle striking plate. Instead of an angular recess 8 ', a trough-shaped, dash-dotted illustrated recess 14 would also be possible, in the event that a multi-locking lock is equipped with locking pins which engage in corresponding striking plates which in turn lie in the recesses 14. In this embodiment, too, the milling recesses are incorporated with the aid of milling gauges.

The milling jig 15 according to the first embodiment, shown in FIGS. 1 to 7, has two parallel ones Carriers 16, 17. The same are tubular and designed as drive shafts. In each case in the same cross-sectional plane, the carriers 16, 17 are firmly connected with gear wheels 18 lying one behind the other in rows. In each case two gear wheels 18 lying in a common cross-sectional plane engage in the toothing 19 of a template fastening rod 20. Furthermore, two adjacent template fastening rods 20 each carry a milling template 21. In the exemplary embodiment, six template fastening rods 20 and accordingly three milling templates 21 are present. The ends thereof are connected to the associated templates 21 by means of fastening screws 22 to form a unit. The supports 16, 17 designed as drive shafts pass through the cantilevers 23 which enclose the template fastening rods 20 in the transverse direction and can be displaced in the longitudinal direction to the fastening rods 20. The gears 18 are in the interior of the boom 23 such that only a parallel adjustment of the boom 23 and thus the carrier 16, 17 is possible. At their free ends, the cantilevers 23 are mounted around pins 24 of clamping levers 25, which bring about transverse displacement of clamping jaws 27 via eccentric surfaces 26. In the exemplary embodiment, each boom carries a tensioning lever 25. However, it would also be possible to equip only the booms assigned to a carrier with tensioning levers.

The carriers 16, 17 can be rotated by means of switchable ratchet ratchets 28 assigned to them, which are equipped with transversely protruding actuating handles 29. Such ratchet ratchet 28 are known per se. They are intended to prevent the deflection of the arms 23 from occurring in the clamping position of the clamping jaws 27. The outer housing of the ratchet mechanism 28 are in Not illustrated manner assigned to the milling jig 15 in a rotationally fixed manner, for example by virtue of the fact that they are firmly connected to the adjacent brackets 23.

Correspondingly figured passage openings 30 for a milling cutter (not shown) are located in the milling templates 21.

The milling templates 21 are carriers of centering projections 31 which rest on the underside of the milling templates 21 and are fixed there by means of retaining screws 32. There is an angular cross section of these centering projections. The width of the downward angled leg corresponds to that of the frame groove 4 of the frames 2 and 12. This configuration allows the milling jig 15 to be placed on the edge region of the door 1, 10 in such a way that the centering protrusion 31 fits appropriately into the frame groove 4. An angularly shaped height stop 33 assigned to an outer arm 23 serves as a reference edge for the milling templates 21.

At right angles to the middle template 21, two parallel, finely adjustable additional milling templates 34 extend. These are carried by the middle boom pairs. For this purpose, each of these brackets 23 is equipped with a downwardly directed support bar 35, in which two parallel rows of threaded bores 36, 37 are provided. A part of these threaded holes 36, 37 are arranged to each other in a gap. In the end regions of the additional milling templates 34 there are two through holes 38, 39 for fastening screws 40 arranged one behind the other. The distance between the fastening holes 38, 39 is greater than the distance between the threaded bores 36, 37 to each other, but smaller than twice the hole spacing of these threaded holes 36, 37, so that an adjustment can be made in steps of 5 mm. The additional milling templates 34 are provided with bores 41, 42, 43 lying one behind the other in rows. The bore 43 guides the milling cutter in order to create the through hole for the handle mandrel on the door. The receiving opening for the locking cylinder can be created by means of the further bores 41, 42. In the present case, the distance between the bores 42 and 43 is 72 mm. If a distance of 92 mm is desired, this is done using a differently designed template. Due to the adjustment of the additional milling templates 34, such a position of the same can be selected so that the predetermined backset is taken into account when milling the transverse openings in the door.

4 it is shown that the milling jig 15 is placed on the edge region of the door 1, centering projections 31 immersing appropriately in the frame groove 4. Before touching down, the clamping jaws 27 or extension arm 23 are in a moved-apart position and thus also the supports 16, 17. The supports 16, 17 serving as drive shafts can now be rotated by means of the actuating handles 29 such that the clamping jaws are driven by the pinion 27 move against each other and get to the door leaf surface in contact position. The final tension is then brought about by means of the tensioning levers 25, which bring the clamping jaws 27 into contact with the door leaf surfaces via the eccentric surfaces 26. The recess, not illustrated, which is subsequently incorporated in the milling process, maintains exactly the center distance A, regardless of the width of the door leaf 1 or the distance between the door surface and the center of the recess to be milled.

The same centering projections 31 are suitable due to their angular cross-sectional design, to be used in the wooden wing 44 illustrated in FIG. 6. Its impact leg 44 'can there in corner contact to the angle profile of the centering projection 31.

Further modifications of the centering projections would be possible, with regard to the correspondingly designed profiles of the edge area of the door.

According to the second embodiment of the milling jig 45, shown in FIGS. 10 to 17, it has a single carrier 46 designed as a square tube. End faces of the same are attached to milling templates 47 with an angular cross-section. At the end of each routing template 47 there is a routing template 48 which is adjustable to the routing template 47. For this purpose, each milling template 48 is carried by an inner tube 49 which can be pushed into the carrier 46 and which engages in a form-fitting manner in the carrier 46. A clamping screw 50 assigned to the milling template 47 allows the distance between the milling templates 47, 48 to be fixed. The minimum distance between these two is determined by a spacer ring 51, which is adapted to the cross-sectional shape of the carrier 46. FIG. 16 shows the released position and FIG. 17 shows the clamping position of the clamping screw 50.

Approximately in the middle region between the two milling templates 47 there is a milling template 52 which can be displaced relative to the carrier in the direction of extension of the carrier 46 between two fixed end positions and which is also designed to be angular in cross section and has openings 53, 54 in both angle legs. In the The opening 53 located in the horizontal angle leg 52 ′ leads to a frame shape in the area there and serves for inserting interchangeable template inserts 55, 56, as illustrated in a top view in FIG. 13. These associated latching means 57 are used to fix the template inserts 55, 56 in the inserted position.

Adjacent to the middle milling template 52 are displaceable further milling templates 58, 59 synchronous to it. The latter as well as the milling templates 47, 48 have the passage openings only in the vertical angle leg.

The displacement path of the other milling templates 58, 59 is greater than that of the first-mentioned milling template 52. The corresponding synchronization takes place via a lever / push rod gear 61. In detail, this has the following structure:
The one additional milling template 58 carries a leaf spring-like arm 62 with an end fixing pin 63. This is assigned two latching openings 64, 65 one behind the other on the carrier 46. From the further milling template 58, a push rod 66 hinges, which is guided past the milling template 52 and which articulates on the milling template 59. A shorter push rod 68 extends from the articulation point 67 there. This engages the end region of a one-armed lever 69. Its articulation point 70 is located on a bracket 71 which is fixedly connected to the carrier 46. Near the articulation point 70, the point of engagement 72 is provided for a further push rod 73. The distance between the articulation point 70 and the point of application 72 corresponds to approximately one third of the lever arm length between articulation point 70 and articulation point 69 'between push rod 68 and lever 69.

If the arm 62 is brought out of its locking position according to FIG. 12, the further milling template 58 can be displaced in the direction of the middle milling template 52. The milling template 52 is also carried along via the lever / push rod gear 61, due to the lever transmission by a smaller distance. After displacement, the fixing pin 63 enters the respective latching opening 65 and fixes the further milling template 58 and the milling templates 52, 59 coupled to it. While the other milling templates 58, 59 cover a path x during such a displacement, the middle milling template 52 moves by a shorter path y. Such a length adjustment is made when the stop direction changes.

The milling templates 47, 58, 59 are each carriers of a fixed jaw 74 and an adjustable jaw 75 lying in the same plane with it. The construction of the latter corresponds to that of the first embodiment, so that it is not discussed in more detail. The clamping jaws 75 are part of a boom 76 which, like a screw clamp, can be displaced on a support arm 77. The latter is firmly connected to the template 47, 58, 59. The fixed clamping jaw 74 is also arranged on the same support arm, cf. in particular FIG. 11. The support arm 77 is fixed by means of a screw 78 which has a longitudinal slot 79 in the support arm 77 reaches through, so that the support arm can be displaced parallel to the horizontal angle leg 52 'within certain limits, accompanied by a change in the position of the fixed clamping jaw 74. The angular interior of the milling templates takes a stepped design Stops 80 on to support the door parts to be machined.

These stops 80 are firmly connected to the milling templates in question.

If the milling templates 58, 59 are adjusted lengthwise, the clamping jaws 74, 75 assigned to them are also shifted.

The aforementioned fixed stops 80 are in opposition to the jaws 75, so that there is an overall stable clamping.

The displaceable and lockable milling templates 48 provided at the end region of the milling cutter 46 are provided with mutually directed stops 81 which step against the corresponding edge regions of the door part to be machined.

14, the milling jig 45 is placed on the edge area of the passive leaf 9 and clamped there. The milling cutters (not shown) can now be fed through the relevant openings in the milling template in the direction of the arrow in order to produce the angular recess 8 '. 14 shows in dash-dotted lines that the trough-shaped recess 14 can be produced by means of a horizontally guided milling cutter for receiving a correspondingly designed striking plate.

15 shows the assignment of the milling device to the frame leg 7. The angular recess 8 there can then be milled by means of the milling cutters fed in the direction of the arrow. By one It is also possible to incorporate a trough-shaped recess 82 ′ using the end mill. The frame leg 7 could, however, also be clamped in a position turned through 90 °, the leg side surfaces 7 ′, 7 ″ then coming into contact with the clamping jaws 74, 75.

In contrast to the first embodiment, the relevant templates 52, 58 and 49 can now be displaced in the direction of extension of the carrier 46 in this second version. The milling templates 48 can then also be adjusted in the direction of extension of the carrier 46.

With regard to the first version, it should also be mentioned that the centering projections 31 can be designed such that they fit in frame grooves which have a width of 16, 18, 20, 24 mm for receiving a flat top. The adaptability is also given for frame grooves, which, for. B. accommodate a U-shaped faceplate.

The third embodiment, shown in FIGS. 18 to 24, is similar to the first embodiment. Also in the third embodiment there are tubular supports 83, 84 designed as drive shafts, which represent drive shafts. In each case in the same cross-sectional plane, the carriers 83, 84 are also firmly connected here with toothed wheels 85 lying one behind the other in rows. In each case two gear wheels 85 lying in a common cross-sectional plane engage in the toothing 86 of a template cross member 87. Furthermore, two mutually adjacent template cross members 87 each carry a milling template 88, 89, 90, which are connected to one another by means of bridge-like centering projections 91 running in the longitudinal direction of the milling template are. The latter are such that a gradual change in distance between the middle milling template 89 and the outer milling templates 88 and 90 can be carried out, which are then provided with end-centering projections 91 '.

The supports 83, 84 can be rotated by means of handles 92 arranged on them, which are connected to the supports 83, 84 in a rotationally fixed manner.

The transverse ends of the milling templates 88, 89, 90 are fixedly connected to the template cross members 87 in a manner not specified. The template crossmembers 87 are comprised of clamping jaws 93 which can be displaced on the crossmembers 87 in their longitudinal direction. The gear wheels 85 lie in the interior of the clamping jaws 93 and only permit parallel adjustment of the clamping jaws 93. There is a certain amount of play in the movement of the clamping jaws 83 on the cross member 87, allowing the clamping jaws 93 to tilt about the carriers 83, 84.

Clamping handles 95 are provided on the side opposite the clamping linings 94 of the clamping jaws 93. Each clamping handle 95 has a threaded shaft 96 which is screwed into a threaded bore of the clamping jaw 93 and which acts via a roller-shaped pressure piece 97 on the narrow surface of the template cross member 87 opposite the toothing 86. In the exemplary embodiment shown, the aforementioned centering projections 91, 91 'enter a rebate-side frame groove 98 of a door 99 illustrated in FIG. 21. This gives the door 99 an exact reference to the passage opening in the milling templates 88, 89, 90.

Also available in this version are two mutually opposite, finely adjustable additional milling templates 100, which in turn are carried by the middle pairs of jaws. As in the first exemplary embodiment, each of these clamping jaws is equipped with a support bar 101 with correspondingly arranged threaded bores for fixing the additional milling template 100 at a predetermined distance from the milling template 89.

Each additional milling template 100 running parallel to the carriers 83, 84 forms a guide rail 102 on which a hole milling jig 103 with a C-shaped cross section can be displaced. The latter can be set in different locking positions. For this purpose, in the exemplary embodiment, the guide rail 102 has three latching openings 104, 105 and 106 on its lower narrow side, which interact with a spring-loaded latching pin 107 of the hole milling jig 103. A compression spring 108 always loads the locking pin 107 in the direction of engagement. If the locking pin 107 is located in the locking opening 104, then a milling cutter of corresponding diameter can be passed through the hole opening 109 and works the milling for the lever handle into the door. The hole opening 109 is formed by the inner ring 109 'of a roller bearing incorporated into the hole milling jig. If the locking pin 107 is withdrawn, see FIG. 24, the hole milling gauge can be displaced such that the locking pin 107 engages in the locking opening 105. Then a cutout can be created at the appropriate point. If this has happened, the hole milling jig 103 can be shifted further so that the locking pin 107 dips into the locking opening 106. In this way, two mutually adjacent, overlapping cutouts can be produced in the door, in which one is assigned to a door Lock cylinder can be used. The locking openings 104 and 105 are spaced 92 mm apart.

If the above-described milling jig 110 is placed on the edge region of the door 99, the centering projections 91, 91 'coming into the stop position relative to the step 98 on the door side, the supports 83, 84 and thus the gears 85 can be rotated by means of the actuating handles 92. At the same time, the clamping jaws 93 are shifted in the bearing position to the broad side surfaces of the door 99. The clamping handles 95 are then brought into the clamping position, the clamping jaws 93 moving into a tilting position, the clamping pads 94 pressing firmly against the side surfaces of the door 99. The tilt angle is designated Alpha in FIG. 21. The corresponding millings in the door 99 can now be made using the milling templates 88, 89, 90. In the exemplary embodiment, the door 99 is then prepared to receive an espagnolette lock with multiple locking.

Also in this version, an adjustable end stop 111 cooperating with the corresponding door transverse edge is provided.

The structure of the milling jig 112 shown in FIGS. 25 to 36 largely corresponds to the milling jig 45 according to the second embodiment. The only carrier 113 is designed as a square tube, on which angularly shaped milling templates 114, 115 are provided at the ends in the longitudinal direction of the carrier 113. By means of clamping screws 116 designed as grub screws, the two outer milling templates 114, 115 can be fixed in relation to the central, also angularly shaped milling template 117.

A stop 118 is provided at each end of the carrier 113 and can be fixed in the selected position by means of a clamping screw 119 on the carrier side.

The middle milling template 117 can be brought into two different end positions and locked there. The end positions are specified by two end stops 120, 121 on the carrier side, which are designed as grub screws. These interact with support pieces 122 screwed to the milling template 117. The one angle leg 117 'of the milling template 117 forms a viewing window 146 and 147, overlapping the carrier 113, on the narrow edges, which interact with stop indicators L and R arranged on the carrier 113. 31, the stop indicator R passes through the viewing window 146, while the other stop indicator L is covered. This means that the milling jig 112 is set to the right stop. This also applies to Fig. 27.

To fix the two end positions of the milling template 117, a plug pin 123 which engages with the carrier 113 is used. This is guided in a bearing block 124 fastened to the milling template 117. A compression spring 125 acts on the plug pin 123 in the direction of engagement. The plug pin 123 works together with two plug openings 126, 127 arranged one above the other. If the plug pin 123 is located in the plug opening 126, the indicator R is visible. Then the support piece 122 acts on the end stop 121.

In order to change the stop direction, the plug pin 123 with the ball handle 128 attached to it must be pulled into the release position against the pressure spring load. Then the middle template 117 can be relative shift to the carrier 113, which is limited by the end stop 120 in cooperation with the other support piece 122. Then the plug 123 is aligned with the plug opening 127 so that the locking engagement can be made there. In this position of the milling template 117, which is then displaced by the dimension z, the stop indicator L passes through the viewing window 147, while the previously visible stop indicator R is now covered, see FIG. 32.

According to this fourth embodiment, on both sides of the central milling template 117 there are cross members 129 that can be connected to it, while only one cross member 129 is assigned to the end milling templates 114, 115, specifically on the side facing the central milling template 117. An abutment 130 connected to the associated milling template is used to hold each cross member 129 for receiving a clamping screw 131, the screw shaft 131 'of which passes through a longitudinal slot of the cross member 129. By loosening the clamping screw 131, the cross member 129 can be displaced relative to the carrier 113 and also to the milling template.

The cross member 129 forms a fixed clamping jaw 132. Opposite this is a clamping jaw 133 which can be displaced on the cross member 129 and to which a clamping lever 134 is assigned. The cross member 129 extends through an opening 135 of the clamping jaw 133. Support pins 136 are provided on both sides of the narrow edges of the opening 135.

The support pieces 122 provided in the angular interior of the milling templates serve to receive fixed stops 137 made of plastic or the like. The latter are guided in a dovetail shape in the support pieces 122 and clamped there by means of the clamping screws 138. Each fixed stop 137 forms a rectangular recess 139 and serves for the stop-limited entry of a leg (frame) 140 on the fixed frame side.

The milling jig 112 is clamped in such a way that the corresponding fold-side corner region of the leg 140 comes to rest in the rectangular recess 139 of the fixed stops 137. Thereafter, the fixed stop 132 is to be brought into contact position with the associated side surface of the leg 140, specifically after the loosening of the clamping screw 131, which is to be tightened in the contact position of the fixed clamping jaw 132. The movable stop is then to be displaced in the direction of the opposite side surface of the leg 140. The clamping position is then achieved by pivoting the clamping lever 134, which brings the clamping jaw 133 into firm contact with this side surface with an eccentric surface and thereby clamps the frame leg 140 firmly. 29, the facing ends of the fixed stops 137 partially cover the fold area to be provided with the milling 141. The overlap is about 1 mm. It is thus ensured that when the angularly shaped cutout 141, which is used to hold an angle striking plate, is worked in, the frame wood does not tear out in the corner region, ie where the milling cutter runs out. FIG. 35 shows the milling cutters 142, 143 which are at right angles to one another, which can be advanced in the direction of the arrow to the corresponding depth and which can also be displaced transversely thereto, that is to say in the direction of the corner of the milling 141. By means of the milling cutter 143 can then also incorporate the pockets 144, 145 starting from the cutout 141. However, there is no need to cover it with fixed stops, since this area is covered after fitting the corresponding angled striking plate.

Corresponding fixed stops 137 can also be assigned to the milling templates 114, 115 adjacent to the central milling template 117, which also prevent the door wood from being torn out.

As in the second embodiment, the milling templates 114, 115, 117 are equipped with exchangeable template inserts, which are not described in more detail.

All the features disclosed are essential to the invention.
