[0002] The invention relates to a drilling guide for making angulated bores for a two-workpiece, flat, mutual juxtaposition pair of connection surfaces with mutually joining screws, 9 with a contact surface applicable to a wide side surface of a first workpiece, the wide side surface to extending essentially perpendicular to the connection surface, in which surface at least one 11 guiding channel for a drill bit opens acutely, and with adjustment elements in order to position 12 the contact surface with various spacings from the opening of the at least one guiding channel as 13 far as the connecting surface limiting edge of the contact surface.
DESCRIPTION OF THE PRIOR ART
16 [0003] A drilling apparatus of this kind is useful where two workpieces are to be screwed 1~ tightly to one another to make an edge bond with one another. A drilling guide of this kind is is described in US 2002/0150434A1. A first workpiece has a contact surface and a binding surface 19 essentially at right angles thereto. The drilling guide has a contact surface with which it can be laid against the wide side surface of the workpiece. This takes place with a defined spacing to 21 the edge between the wide side surface and the bonding surface of the workpiece. The bonding 22 surface of the workpiece is usually a narrow side surface. This narrow side surface is generally 23 brought against a surface, for example a wide side surface, of a second workpiece. In this 24 arrangement the two workpieces are connected together. With the drilling guide it is possible to provide bores at acute angles in the broad side, whose individually imaginable elongation ends 26 about in the middle of the narrow side. The strength of the material for the first workpiece 27 determines the individual gap from the edge between the wide side surface and the binding 28 surface. This brings into play the known drilling guide adjustment elements. For the guidance 29 of the drill bit are used several guiding channels which are parallel with one another.
21400182.3 (CA version) 1 2 [0004] It is one aspect of this invention to provide a drilling guide of the above-named kind, 3 with improved functioning.

16 [0003] A drilling apparatus of this kind is useful where two workpieces are to be screwed 1~ tightly to one another to make an edge bond with one another. A drilling guide of this kind is is described in US 2002/0150434A1. A first workpiece has a contact surface and a binding surface 19 essentially at right angles thereto. The drilling guide has a contact surface with which it can be laid against the wide side surface of the workpiece. This takes place with a defined spacing to 21 the edge between the wide side surface and the bonding surface of the workpiece.

This brings into play the known drilling guide adjustment elements. For the guidance 29 of the drill bit are used several guiding channels which are parallel with one another.
21400182.3 (CA version) 1 2 [0004] It is one aspect of this invention to provide a drilling guide of the above-named kind, 3 with improved functioning.
[0005] In one aspect, the present invention provides a drilling guide for making angulated bores for a two-workpiece, flat, mutual juxtaposition pair of connection surfaces with mutually joining screws, with a contact surface applicable to a wide side surface of a first workpiece, the wide side surface extending essentially perpendicular to the connection surface, in which contact 8 surface at least one guiding channel for a drill bit opens acutely, and with adjustment elements in 9 order to position the contact surface with various spacings from the opening of the at least one 1o guiding channel as far as the connecting surface limiting edge of the contact surface, wherein the 11 contact surface has a carriage support on which a carriage, displaceable parallel to the contact 12 surface, and lockable in various positions, has the said at least one guiding channel.
13 [0006] In another aspect of the invention, it is provided that the contact surface have a 14 carnage support on which at least one guiding channel-providing carnage is secured, the carriage being movable parallel to the contact surface and capable of being fixed in various positions.
16 Upon dislocation of the carnage with respect to the carnage support, the guiding channels can be 1'7 brought to another spaced position with respect to the edge between the wide side surface and the 1s bonding surface, in order to adjust the drilling guide to different material strengths of the first 19 workpiece.
[0007] In a preferred embodiment of the invention there is provided a pivotal stop, this being 21 located at the edge of the front face provided by the edge of the contact surface. In one stop 22 position the pivotal stop can be brought against the attachment surface. In a returned pivotal 23 position the pivotal stop can for example be in alignment with the attachment surface. It can 24 then for example be laid against the wide side surface of a second workpiece, which lies in flat disposition with respect to the binding surface.
26 [0008] The drilling guide in accordance with the invention can have two parallel guide 2'7 channels. In accordance with this, the carnage can have two elongate through openings for the 28 drill bit.
29 [0009] In a preferred further development of the invention there is provided, between the two 3o elongate openings, an elongate slot provided with detent niches. The latter is penetrated from the 31 wide side of the carriage by a drop-in pin. A detent head of the drop-in pin can lie in the detent 21400182.3 (CA version) niche. By exerting pressure on the detent pin, the detent head can be moved out of the detent 2 niche, thereby to dislocate the carriage relative to the carnage support.
The detent head, by 3 pressure on a push-button, can be dismounted out of the detent niche against the replacement force of a spring. Further it can be foreseen that the detent niches, in various separations from the pivotal stop, are rearwardly open to the contact surface, and the detent head of the detent
13 [0006] In another aspect of the invention, it is provided that the contact surface have a 14 carnage support on which at least one guiding channel-providing carnage is secured, the carriage being movable parallel to the contact surface and capable of being fixed in various positions.
16 Upon dislocation of the carnage with respect to the carnage support, the guiding channels can be 1'7 brought to another spaced position with respect to the edge between the wide side surface and the 1s bonding surface, in order to adjust the drilling guide to different material strengths of the first 19 workpiece.
[0007] In a preferred embodiment of the invention there is provided a pivotal stop, this being 21 located at the edge of the front face provided by the edge of the contact surface. In one stop 22 position the pivotal stop can be brought against the attachment surface. In a returned pivotal 23 position the pivotal stop can for example be in alignment with the attachment surface. It can 24 then for example be laid against the wide side surface of a second workpiece, which lies in flat disposition with respect to the binding surface.
26 [0008] The drilling guide in accordance with the invention can have two parallel guide 2'7 channels. In accordance with this, the carnage can have two elongate through openings for the 28 drill bit.
29 [0009] In a preferred further development of the invention there is provided, between the two 3o elongate openings, an elongate slot provided with detent niches. The latter is penetrated from the 31 wide side of the carriage by a drop-in pin. A detent head of the drop-in pin can lie in the detent 21400182.3 (CA version) niche. By exerting pressure on the detent pin, the detent head can be moved out of the detent 2 niche, thereby to dislocate the carriage relative to the carnage support.
The detent head, by 3 pressure on a push-button, can be dismounted out of the detent niche against the replacement force of a spring. Further it can be foreseen that the detent niches, in various separations from the pivotal stop, are rearwardly open to the contact surface, and the detent head of the detent
6 stem must cross the contact surface in order to exit from the detent niches.
This ensures that if '7 the drill guide lies to the wide side surface of the workpiece, the locating device cannot be pulled s up. Marks can be placed on the carriage or the carnage support to identify the strength of the material in the workpiece to be worked. This makes easier the preliminary steps of the mounting of the carriage to the carnage support.
11 [0010] Within the guiding channels, metal bushings can be provided.
Following the 12 insertion of the metal bushings, the affected region of the guiding channels should be covered 13 with hard material. This minimizes abrasion. The swivelling stop can have two notches for the 1~ drill bits. This is of advantage if the first workpiece has a low material strength, or if the attachment screw is very close to the edge. The carriage can be mounted along an edge. The 16 drop-in pin extending through the elongate slot can provide, with the end of the elongate slot, a 1'7 movement stop for the carnage. The pivoting stop also can provide a movement stop for the 1s carriage. To simplify the mounting of the carnage on the carriage support, a keyhole-shaped 19 opening can be provided in the end region of the elongate slot, through which the detent head of 2o the detent pin can extend during the mounting of the carriage and the carriage support.
2 ~ [0011 ) The drop-in pin extending through the elongate slot can form a movement stop for the 22 carriage. Also the rotary stop can form a movement stop for the carriage.
To simplify the 23 mounting of the carriage on the carriage support, a keyhole-shaped opening can be provided in 2a the end region of the elongate slot, through which the detent head of the detent pin can be inserted during the mounting of the carriage and the carriage support.

2'7 BRIEF DESCRIPTION OF THE DRAWINGS
28 [0012] An example embodiment of the invention is described below utilizing the attached 29 drawings. The drawings show:
[0013] In Fig 1 a perspective view of the example embodiment of the invention, 21400182.3 (CA version) 1 [0014] In Fig 2 a perspective view, seen from underneath, of the example embodiment of the 2 invention, 3 [0015] In Fig 3 a section through a completed corner connection in accordance with the example embodiment illustrated in Figs. l and 2, [0016] In Fig 4 an exploded illustration of the individual parts of the drilling guide according 6 to the example embodiment, '7 [0017] In Fig 5 a plan view of the drilling guide, s [0018] In Fig 6 a front elevation of the example embodiment, with a pivotal stop member 9 pivoted to a stop position, [0019] In Fig 7 a bottom plan view of the example embodiment, 1 ~ [0020] In Fig 8 a section taken at the line VIII-VIII in Fig S, 12 [0021] In Fig 9 a section taken at the line IX-IX in Fig 5, 13 [0022] In Fig 10 a section in accordance with Fig 8, with the detent head out of the detent 14 position, is [0023] In Fig 11 a section in accordance with Fig 8, with the carriage displaced with respect 16 to the carnage support, 1'7 [0024] In Fig 12 a section in accordance with Fig 9 in another decent position of the carnage 1 s with respect to the carnage support, and in stop position on a workpiece, 19 [0025] In Fig 13 a front elevation to demonstrate the pivotal nature of the pivotal stop, [0026] In Fig 14 an illustration according to Figure 13 with the pivotal stop moved out of the 21 stop position, and 22 [0027] In Fig 15 a second stop position on a first workpiece, the latter forming a butt joint 23 with a second workpiece, in which the second workpiece forms a stop surface for the front edge 24 of the pivotal stop.
2'7 [0028] The apparatus shown in the drawings serves to drill an acute-angled hole in the broad 28 side of a workpiece. What are meant here are blind holes having a diameter larger than the 29 screw-head diameter of a screw which is screwed into the blind hole. The bottom of the bore 3o forms a reduced-diameter finder opening for the point of the screw. This finder opening can 31 extend as far as the narrow side 1' of the workpiece 1. With the inserted or screwed-in screw 3 21400182.3 (CA version) 4 1 in the bore 4, the workpiece can be connected at an obtuse angle, in particular at right angles to a 2 second workpiece 2 either as shown in Figure 3 constituting an edge joint, or as shown in Figure 3 15. The screw should be located approximately in the middle of the narrow side surface 1', in 4 order for it to be screwed into the broad side surface of the second workpiece.
[0029] However, this arrangement allows not only the construction of edge joints. The 6 surface 1' can also be brought into contact with a narrow side surface of a second workpiece, for
7 example in order to elongate a board.
8 [0030] As can be particularly seen in Figure 4, the drilling guide includes a carnage support
9 9, which as a result of edge-located ribs, forms guide-grooves 23. The guide-grooves 23 open 1 o towards each other. The bottom of the cazriage support 9 forms two parallel extending openings 11 12. These are formed as elongate slots and extend almost over the entire length of the carriage 12 support 9. Between the two openings 12 is located an elongate slot 14 which forms a total of 4 13 circular detent niches 13, wherein one detent niche is located at the end of the elongate slot 14.
14 The other end of the elongate slot 14 forms a keyhole-shaped opening 22, through which the detent head 15' of a detent drop-in pin 15 fits.
16 [0031] A protuberance on the narrow surface of the carriage support 9 forms a threaded 17 opening 31 for a threaded screw 25. The threaded screw 25 rotatably mounts a swivel stop plate 18 11 on the head of the carriage support 9.
19 [0032) The swivel stop plate 11 can be rotated about the screw 25 which is located midway of the side surface of the carriage support 9. In a stopped condition, a section of the swivel stop 21 plate 11 provided with notches 20 extends over the rearward contact surface 5 of the carnage 22 support 9, so that the latter, as seen in Figures 8 and 9, can be laid against the narrow side 1' of a 23 workpiece, against the broad side surface of which the carnage support 9 rests with its contact 24 surface. In the position which is 180 degrees rotated, the front side of the swivel stop plate 11, according to Figure 15, functions as a stop.
26 [0033] Moreover, the drilling guide in accordance with the invention includes a sliding 27 carriage 10. This carriage defines opposed guiding pegs 24, which engage within the guiding 28 grooves 23 in such a way that the carnage 11 is guided to remain within the essentially U-shaped 29 recess between the two edge ribs of the carnage support 9.
[0034) The carriage 10 has two parallel extending guiding channels 6. The guiding channels 31 6 begin at a narrow side of the carriage 10 and end on the wide side thereof on the bottom of the 21400182.3 (CA version) 1 carriage support 9, in alignment with the above-mentioned opening 12. At least the insertion-2 side portion of the guiding channels 6 is covered with a metal jacket 19.
The metal jackets 19 3 project into the two parallel running guiding channels 6 which define an acute angle with the 4 broad side.
[0035] The mounting of the carnage on the carnage support 9 takes place prior to the 6 connection of the detent drop-in pin 15, utilizing the assigned push-button 16. After the insertion 7 of the slide 9 (?) into the guide track of the carriage support 9 (?), the detent drop-in pin 1 S is 8 inserted from the stop (?) surface 5 through the elongate slot 14 to reach the appropriate bore in 9 the carnage 10(?). Following the positioning of a compression spring 17 against the bottom of a 1o cup-shaped recess 28, the push button 16 is screwed mounted or adhered in place.
n [0036] The detent head 15' of the detent drop-in pin 15 lies within one of the detent niches 12 13 in such a way that the carnage 10 cannot become dislocated with respect to the carnage 13 support 9.
14 [0037] Pressure on the push-button 16 causes the detent head 15' to be displaced out of the detent niche 13 assigned to it. In this position, the carnage 10 can become dislocated between 16 two end stop positions with respect to the carnage support 9. In a first end stop position, the m carriage 10 lies in position with respect to the swivelable detent plate 11.
In this position, the I8 detent head 15' is located in the detent niche 13 which is immediately adjacent the keyhole-19 shaped opening 22. The other end detent is formed from the detent niche 13 located at the end of 2o the elongate slot 14.
21 [0038] In each of the total of four detent niches provided in the example embodiment, the 22 guiding channel 6 communicates with a different distance to the swivel plate 11 so that, in this 23 way, the position of the screw 3 in the narrow side 1' of the workpiece 1 can be defined. When 24 working with thin workpieces l, the carnage 10 would be in the detent position shown in Figure 9. With very thick workpieces the carnage 9 is found in a detent position, as is shown in Figure 26 15. The apparatus functions as follows: dependent upon the material strength of the workpiece 1 2'7 and the nature of the stop, whether the front or rear of the detent plate 11 serves as the stop, the 28 carnage 10 is brought to a corresponding detent niche with respect to the carnage support 9.
29 [0039] Then, the apparatus is brought with its surface 5, using either the rear side or the front 3o side of the rotatable stop 11, as a stop surface relative to the narrow side 1' of the workpiece 1.
31 The drilling guide is then fixed to the workpiece 1 with a tension clamp, utilizing the tension 21400182.3 (CA version) 6 1 clamp surface 26. Next, the bore depth is set for the drill bit 7, utilizing a depth stop ring 29.
2 The drill bit 7, inserted into the chuck of a drilling machine, is then introduced into the guiding 3 channel 6, in order to create the bore 4. The finder opening for the point of the screw 3 is made 4 by the reduced point 30. With one tension setting, two parallel bores can be drilled.
[0040] All disclosed characteristics are important for the invention. Within the disclosure of 6 the application the content of the disclosure of the corresponding/hereto-attached priority '7 documents (copy of the foregoing application) are included with all contents, also with the purpose of including characteristics of these documents in the claims of the present application.
21400182.3 (CA version) 7
14 The other end of the elongate slot 14 forms a keyhole-shaped opening 22, through which the detent head 15' of a detent drop-in pin 15 fits.
16 [0031] A protuberance on the narrow surface of the carriage support 9 forms a threaded 17 opening 31 for a threaded screw 25. The threaded screw 25 rotatably mounts a swivel stop plate 18 11 on the head of the carriage support 9.
19 [0032) The swivel stop plate 11 can be rotated about the screw 25 which is located midway of the side surface of the carriage support 9. In a stopped condition, a section of the swivel stop 21 plate 11 provided with notches 20 extends over the rearward contact surface 5 of the carnage 22 support 9, so that the latter, as seen in Figures 8 and 9, can be laid against the narrow side 1' of a 23 workpiece, against the broad side surface of which the carnage support 9 rests with its contact 24 surface. In the position which is 180 degrees rotated, the front side of the swivel stop plate 11, according to Figure 15, functions as a stop.
26 [0033] Moreover, the drilling guide in accordance with the invention includes a sliding 27 carriage 10. This carriage defines opposed guiding pegs 24, which engage within the guiding 28 grooves 23 in such a way that the carnage 11 is guided to remain within the essentially U-shaped 29 recess between the two edge ribs of the carnage support 9.
[0034) The carriage 10 has two parallel extending guiding channels 6. The guiding channels 31 6 begin at a narrow side of the carriage 10 and end on the wide side thereof on the bottom of the 21400182.3 (CA version) 1 carriage support 9, in alignment with the above-mentioned opening 12. At least the insertion-2 side portion of the guiding channels 6 is covered with a metal jacket 19.
The metal jackets 19 3 project into the two parallel running guiding channels 6 which define an acute angle with the 4 broad side.
[0035] The mounting of the carnage on the carnage support 9 takes place prior to the 6 connection of the detent drop-in pin 15, utilizing the assigned push-button 16. After the insertion 7 of the slide 9 (?) into the guide track of the carriage support 9 (?), the detent drop-in pin 1 S is 8 inserted from the stop (?) surface 5 through the elongate slot 14 to reach the appropriate bore in 9 the carnage 10(?). Following the positioning of a compression spring 17 against the bottom of a 1o cup-shaped recess 28, the push button 16 is screwed mounted or adhered in place.
n [0036] The detent head 15' of the detent drop-in pin 15 lies within one of the detent niches 12 13 in such a way that the carnage 10 cannot become dislocated with respect to the carnage 13 support 9.
14 [0037] Pressure on the push-button 16 causes the detent head 15' to be displaced out of the detent niche 13 assigned to it. In this position, the carnage 10 can become dislocated between 16 two end stop positions with respect to the carnage support 9. In a first end stop position, the m carriage 10 lies in position with respect to the swivelable detent plate 11.
In this position, the I8 detent head 15' is located in the detent niche 13 which is immediately adjacent the keyhole-19 shaped opening 22. The other end detent is formed from the detent niche 13 located at the end of 2o the elongate slot 14.
21 [0038] In each of the total of four detent niches provided in the example embodiment, the 22 guiding channel 6 communicates with a different distance to the swivel plate 11 so that, in this 23 way, the position of the screw 3 in the narrow side 1' of the workpiece 1 can be defined. When 24 working with thin workpieces l, the carnage 10 would be in the detent position shown in Figure 9. With very thick workpieces the carnage 9 is found in a detent position, as is shown in Figure 26 15. The apparatus functions as follows: dependent upon the material strength of the workpiece 1 2'7 and the nature of the stop, whether the front or rear of the detent plate 11 serves as the stop, the 28 carnage 10 is brought to a corresponding detent niche with respect to the carnage support 9.
29 [0039] Then, the apparatus is brought with its surface 5, using either the rear side or the front 3o side of the rotatable stop 11, as a stop surface relative to the narrow side 1' of the workpiece 1.
31 The drilling guide is then fixed to the workpiece 1 with a tension clamp, utilizing the tension 21400182.3 (CA version) 6 1 clamp surface 26. Next, the bore depth is set for the drill bit 7, utilizing a depth stop ring 29.
