DRILL POSITIONING DEVICE

This invention relates to a drill positioning device for use when it is desired to drill holes in material, particularly when it is desired to drill holes in a number of items in repetitive fashion so that the holes are correctly located and properly spaced on a plurality of e.g. doors or drawer fronts where the holes are necessary for affixing handles to the doors or drawer fronts. To measure and mark the positions for the door handles, cabinet or drawer pulls manually, one-by-one, is a very time-consuming operation and often results in mistakes which if not detected, cause damaged or wasted materials.

One particular area where repetitive accurate hole positioning is needed is in fitting kitchen units where it is desired to position handles on drawer fronts and cupboard doors. In order that the final appearance is satisfactory, the handles need to be placed exactly correctly and this is not easy to achieve satisfactorily in the absence of some sort of drilling guide to make the customary holes through which the fastener or pull is fixed. This applies equally to pull or handle types where a threaded bolt is passed through the hole(s) from the interior of the drawer or cupboard and screwed into a threaded hole in the handle or pull itself, and to cases where the handle or pull has one or more shafts extending from it which may pass through the door or drawer front from the outside and on to the end(s) of which a nut or like fastener is threaded to secure the pull or handle in place.

A second area where accurate and reproducible hole positioning is needed is when fitting locks into doors, where holes need to be drilled to take the shaft on which a door handle is to be mounted and separately a hole for the barrel of the cylinder lock portion which allows the door to be locked or released using a key.

A wide variety of jigs for assisting drill positioning is known in the prior art patent literature. Specification US-A-1269811 discloses a jig for accurately positioning holes for dowelling and GB 2444555A discloses a jig for cutting a mortice pocket in the leading edge of a door. Somewhat more developed arrangements are disclosed in US Specification 2560382, US-A-5807036, US-A-4684299, US-B-7189035, US-A-5743684 and International Published Application WO 2007/123415. A folding drill jig design is illustrated in US Design Patent 334700.

These various specifications disclose a variety of apparatus in which the position of a guide hole for a drill can be adjusted relative to a framework, which framework is itself positioned relative to a furniture or like component, such as a door or drawer front, in order to enable drilling at the desired position(s).

A major disadvantage of the jig apparatus disclosed in these prior art documents is that they are not adapted for use in two positions, for example either side of a panel such as a door where the drilling desirably needs to take place from both sides of the panel and where accordingly the device needs to be positioned first to one side and then to the other side of the panel without any loss of accurate positioning. This cannot be done easily, or indeed at all, with the devices described in the prior art documents noted above.

In accordance with the present invention, there is provided an adjustable drill positioning jig comprising a planar frame, usually rectangular, an elongate cross-member set within the frame, and adjustable in position relative to the frame and where means are provided to releasably fix the position of the cross-member relative to the frame, and one or more drill guide members adjustably positioned on the cross-member and provided with means for releasably fixing each drill guide member at a desired position along the cross-member, a rail or flange running along one edge of the frame and extending in a plane perpendicular to the plane of the frame, a retractable adjustable projection set on an adjacent edge of the frame and which when extended extends on the same side of the frame as the rail or flange, and wherein both sides of the rectangular frame are free of projections. The adjustable projection when retracted is moved from a position extending the same side of the frame as the rail or flange to a position in which it does not project past the contour of the frame itself, so enabling the flat side of the frame to be laid in contact with the side of the panel in which drill holes are to be made.

Jigs in accordance with the present invention are configured in a way which overcomes the disadvantages of the known jigs referred to above, in particular because they can be used in any situation where the same hole positions are needed in a set or series of different workpieces. In particular, the jigs of the present invention can be used in the manner of a template against one side of a workpiece and then simply turned over and positioned to mirror the hole positions on the other side of the workpiece, which can be for example a room door or a cabinet door or drawer front.

In a preferred embodiment the jig consists of a rigid rectangular metallic frame, a cross-piece acting as a guiding element and coupled to the frame and two (or more) re-locatable drill blocks, which constitute the drill guiding m members, coupled to the guiding element, where the drill blocks can slide in and along the cross-piece and the cross-piece is mounted so it can slide on the frame in the orthogonal direction to its length. This enables the positions of the drill blocks to be configured to define the desired positions of the holes, where the position of each drill block on the cross-piece can be locked by means of a tightening bolt and the position of the cross-piece on the frame can be locked by means of two tightening bolts.

Such drill blocks may be in the form of a simple rectangular block with a circular hole going through it perpendicular to one face of the block. In order to provide adjustability, the hole may be dimensioned to correspond with the largest likely drill size, and if it is desired to use a smaller drill size, then a hollow cylindrical insert may be fitted into the block, the insert having an exterior diameter which corresponds to the diameter of the hole in the block and an interior diameter corresponding to the diameter of the desired drill size.

A preferred construction for the drill blocks is for each to consist of a rectangular frame which is movably positioned on the cross piece and which receives a rectangular guide which has a bore in it corresponding to the desired drill size. Such a “sub-block” may be easily inserted into or pulled from the rectangular frame, and may be held in position by a suitable catch mechanism. One such approach is to use a sprung ball mounted in the rectangular frame and provide a depression or groove in the sub-block into which the ball is pressed when the sub-block is correctly located. Alternatively, in place of a spring ball, a leaf spring with a free end adapted to lodge in a depression or groove in the sub-block may be provided.

The aperture in the sub-block may be a simple cylindrical aperture or it may be, for example, a specialised shape, for example of an elongate roundended slot with one end enlarged into a circular shape so that the hole resembles a keyhole and can be used to make a hole in a door through which the projecting barrel portion of a door security lock conforming to the Eurolock standard may be passed.

Such a jig may be used in the following way to enable the repeated accurate location of drill holes in doors, cabinets or drawers:

In use, the rail and projection are positioned adjacent the top and a side edge of a drawer or against the edge and bottom of a door so that the crossmember lies against the front of the door or drawer and the cross-member and drill guides are then located where desired, e.g. by sliding the crossmember relative to the frame and sliding the drill guide(s) relative to the cross-member, whereafter the means for locking the position of the cross5 member relative to the frame and for locking the position of the drill guide or guides relative to the cross-member are actuated. The drill guide or guides are conveniently simple blocks having a through-hole extending in a direction perpendicular to the plane of the frame.

Preferably the planar frame, the cross-member and the drill guides are all of the same thickness, i.e. of the same dimension in a direction perpendicular to the plane of the frame.

The rail or flange running along one edge of the frame preferably extends to each side of the frame so that the device can be placed with the rail adjacent

e.g. one edge of the door with the drill guide units on the inside or on the outside. This is particularly valuable where the drill guide has two holes in it, one for a relatively smaller size drill and the other for a relatively larger size drill, so enabling e.g. a relatively small hole to be drilled from the front of the door using the frame adjacent the front of that door and then, by placing the frame on the other side of the door, and adjusting the position of the drill blocks so that the other holes are in the same position as the first holes were to start with, a relatively larger hole may be drilled into the door to provide a counter-bored section into which the handle fitment may subsequently enter when it is screwed on to the threaded portion conventionally extending from the handle itself.

If the drill guide has a relatively large aperture, the relatively small aperture may be easily produced by inserting a collet or the like into the large aperture where the internal diameter of the collet corresponds to the smaller desired aperture, i.e. a small drill will go through the collet and be accurately aligned with the larger drill which goes through the drill guide when the collet is removed, and which is then used to make the counter-bore. This avoids having to adjust the position of the drill guide blocks.

In a further alternative construction, the drill guide blocks may each have a threaded hole into which an externally threaded collet may be screwed. The internal diameter of the collet may correspond to a given drill size, e.g. 4mm, 6mm. The end of the collet may have a slot enabling the collet to be easily screwed into the drill guide block using a flat-head screwdriver, and for removing it if the collet has become worn or damaged or needs to be exchanged for one of a different internal diameter.

The edges of the frame may bear scale markings to enable e.g. the crossmember to be accurately positioned parallel to one of the frame edges. The cross-member may likewise bear scale markings, conveniently extending from a centre point, enabling the two drill guides to be accurately positioned relative to that centre point, i.e. to be positioned equal distances from it. The drill guides preferably carry a marking such as a line or arrow to assist in accurately and repeatably positioning each guide relative to the scale.

The invention is illustrated by way of example with reference to the accompanying drawings in which:

Referring generally to Figures 1 to 14 of the drawings, the device shown consists basically of a rectangular frame 1, the short edges of which have a slot 2 running through them in a plane parallel to the general plane of the frame 1. Located between those short edges is a cross-member 3 which may be positioned as desired along the slots 2. Screwed into the ends of crossmember 3 are screw-threaded knobs 4 which can act to hold the position of cross-member 3 where desired in the slots 2.

Mounted on cross-member 3 are two drill guides 6, each of which consists of a block slidable in an elongate slot 7 in cross-member 3. The position of each drill guide may be fixed by way of a clamping screw 8. The two drill guides shown may be easily positioned equidistant from the centre of the cross-member 3 by aligning marking arrows on the drill guides with a scale 10 which is applied to the cross-member 3.

The ends of the frame also bear scales 11 enabling the two ends of the cross-member 3 to be accurately positioned by aligning the two arrows 12 on its ends at the same position along the scale 11.

Along one edge of the frame is a plate 15 extending to either side of the frame which may be used to locate the device against the edge of a door or drawer front. The centreline of the plate is identified by an engraved line 16 running across it. Adjacent the plate 15 on one side of the frame 1 is a further scale 13.

Located adjacent one corner of the frame remote from plate 15 is a plate 17 which can be clamped in the position shown in Figures 2 to 5 or which, if desired (for example if the frame is to be inserted inside a drawer front), can be twisted to lie against the frame 1, in the position shown in Figure 1, so that it does not then project from the frame, enabling the whole of the side of the frame 1 to be laid flat against the door or drawer front. Clamping is achieved by means of a threaded clamping knob 18.

The use of the device as described is as follows:

The metallic plate 15 extending both sides of the plane of the frame 1, serves as an edge guide to contact the edge of the door or drawer being drilled. To align the frame with the side perpendicular to this edge of the object to be drilled, a small metallic plate 17 is provided on one of the corners of the frame 1.

The adjustable drill hole template can be used in both ways: vertically and horizontally. When the template is used in the vertical way (normally is used for drilling holes for cabinet pulls/door handles or any other surfaces) the small metallic plate 17 will be open as shown in Figures 2 to 11. When the template is used in the horizontal way (normally is used for drilling holes for drawer knobs/handles or any other surfaces) the small metallic plate 17 will remain closed as shown in Figure 1. The position of the small metallic plate 17 is locked by means of the tightening bolt 18.

The rectangular frame 1 is provided with a numerical linear guiding tracks or scales 11, 13. There is one numerical linear guiding track 13 on the left side of the rectangular frame and there are two identical tracks 11 on the short sides of the rectangular frame 1.

These numerical linear guiding tracks are used for making adjustments when the template is in vertical position, so that the position of the drill guides matches the desired position of the holes to be drilled so that e.g. cabinet pulls or door handles may be fixed to door or drawer fronts or any other surfaces. Numerical linear guiding track 13 on the left side of the rectangular frame is numbered from 0 to “n” (“n” - depending on the size of the template). Numbering starts at the bottom of the frame and going up. Numerical linear guiding tracks 11 on the short sides of the rectangular frame 1 are numbered from 0 to “n” (“n”- depending on the size of the template). Numbering starts from left and going to the right. All these numerical linear guiding tracks are marked in one colour: black (black colour corresponds to the vertical position of the template).

Movably fixed on the frame 1 is the sliding element 3 that guides the sliding of the drill blocks 6. With the rectangular frame 1 in vertical position the guiding element 3 can be moved in both directions, right to left and left to right.

The sliding of the guiding element 3 is enabled by rods extending from both ends of the guiding element 3, that go through the frame 1 in the channel 2 that is located in both short sides of the rectangular frame 1. These rods are threaded to receive the tightening bolts (thumb nuts) 4.

Alternatively the guiding element 3 may be is held in the correct desired position (conforming to a desired position of the holes) on a template, by tightening the two thumb nuts 4 which have projecting threaded rods on them which go all the way through the slots 2 in the sides of the rectangular frame 1, and are screwed into the ends of the guiding element 3.

The guiding element 3 is provided with a numerical linear guiding track 10 on the right edge and with a linear (only) guiding track on the left edge. The numerical linear guiding track 10 from the right edge is used for making adjustments when the template is in horizontal position (drilling holes for drawer knobs/handles or any other surfaces).

The numerical linear guiding track 10 is numbered from 0 to n (“n” depending on the size of the template). Numbering starts in the centre of the guiding element (with “0”) and going in both directions, up and down.

This numerical linear guiding track 10 may be marked in red (red colour corresponds to the horizontal position of the template).The linear guiding track on the left edge of member 3 will match with the numerical linear guiding track on the left side of the rectangular frame 1. This linear (only) guiding track is marked with black (black colour corresponds to the vertical position of the template).

The position of the holes in blocks 6 is given by two factors: (1) the position of the guiding element 3 on the frame 1 and (2) the position of the drill blocks 6 that can slide inside the guiding element 3.

When the adjustable drill hole template is in vertical position, the sliding direction of the drill blocks 6 is perpendicular to the sliding direction of the guiding element 3 so that any position of the holes can be easily obtained. Inside the guiding element there is a channel on both sides, that allows the drill blocks to stay fixed in position and also allows the drill blocks to move up and down on that guiding element. The drilling blocks 6 can be moved independently of each other. The guiding element 3 can carry two or more drilling blocks 6.

The sliding of the drilling block is enabled by rods extending from both sides of the drilling blocks. The rods move through the guiding element in the channel that is made on both sides (left side and right side) of the guiding element 3. These rods are threaded to receive the tightening bolts (thumb nuts) 8 only on right side of the guiding element 3.

Each drilling block 6 is provided with a bore therethrough (size varies) to guide the drill bit, so that the drill bit is maintained during drilling the hole perfectly perpendicular to the surface of the object in which the holes are to be made. The centre of each drilling block 6 is marked with a red line, which also corresponds with the centre of the bore.

The drilling blocks may be set in position using the numerical linear guiding track 10 on the right side of the guiding element 3, and then the position of each drill block 6 on the guiding element 3 locked by means of a tightening bolt 8.

The drill blocks 6 are made of a hardened material to withstand wear after repeated use with a drill bit.

Once the drilling blocks 6 are in the right (needed) position to give the desired spacing of the holes, their position can be locked and the frame can be used to provide holes in any other object where the same hole positions are needed. The template can be turned over and used on either side, in order to provide a mirror configuration of the hole positions for different doors or cabinets.

If desired, the adjustable drill hole template may be held in position during drilling by means of a suitable clamp which acts to clamp the template relative to the door, drawer or the like being drilled. One form of such a clamp is shown in the left-hand part of Figure 12. It consists of a U-section block 20 having, extending from one arm of the block, a large leaf spring 21. The block 20 is a close fit in a rectangular aperture 22 formed in one side of the frame 1 of the template. When the block 20 is inserted into aperture 22, the leaf spring lies behind the frame. In its unstressed condition, a portion 23 of the spring 21 lies a short distance away from the plane of the side of the frame 1, but the end of the spring may easily be moved to flex the spring away from the frame, so enabling the template to be held during use against a door or drawer front with the frame lying against one side of the door/drawer front and the portion 23 of the spring 21 pressing against the opposite side of the door or drawer front.

The interior width of the template, i.e. the space between the sides of the frame 1 may be chosen sufficient to be able to drill holes at a maximum distance from the edge of the door or cabinet. The interior length of the template sets the limits on how far apart two holes may be drilled. The device may be produced in a range of sizes to suit particular applications.

Referring now to Figures 15 and 16, these show a device very similar to that shown in Figures 1 to 14 but where the cross-member 3 carries two slidable guiding blocks 31 and 32. Guide block 31 has a central cylindrical hole through it while guide block 32 has a hole through it corresponding to the shape of the keyhole shaped proportion of a Eurolock which, when the Eurolock is installed against one side of the door, it is inserted into a hole in the door. Figure 15 shows that portion, denoted 35, and it can be seen that this contains the standard elongated slot 36 into which the operative end of a key 37 may be inserted in order to operate the Eurolock.

If it is desired to use the device shown in Figures 15 and 16 in the same way as the device shown in Figures 1 to 14, two collets 40 may be fitted into the drill blocks 31 and 32, each collet having an internal diameter corresponding to the drill size desired to make the holes in a door drawer front or the like.

Figures 17 to 26 show a further embodiment of the invention where, in place of the screw-threaded knobs 4, the cross-member 3 is clamped in position by two machine screws 42 and plate 17 is likewise clamped in position by a third machine screw 42. Each of the drill guide blocks consists of an outer block which can be clamped in position on cross-member 3 by means of a further machine screw 42 and an inner sub-block 45, 46 which fits into block

43. The ends of each sub-block have a groove in them into which the end of a leaf spring 48 engages. The groove is easiest seen in Figure 21 where it is denoted 50 and part of the external wall of sub-block 45 is gently sloped, denoted 51, so enabling the sub-block to be pushed into block 43 until the edges of leaf springs 48 engage in grooves 50. Figure 23 shows a block 43 into which a desired sub-block 45, 46, 55, 56 or 57 may be fitted. Each has a groove 50 adjacent an angled wall 51 to enable it to be easily inserted.

In Figures 17 to 19, the scales and index markings on the various 10 components are omitted for the sake of simplicity; in a practical embodiment, they would be marks analogously to the jigs shown in Figures 1 to 16.

Figures 24 to 26 show an alternative construction for the drill block denoted 60 and sub-block denoted 61. At one end of sub-block 61 there is a groove

62 into which a ball 63 may engage when sub-block 61 is inserted into block

60. The block 60 has a small land 64 and the bottom corners of sub-block 61 are cut away at 65 so that the sub-block 61 cannot be pushed all the way through block 60. When sub-block 61 is inserted, ball 63 is pushed back against a spring 67 held in place against an end plate 68 held into the end of block 60 by two screws 69.
