-1 DOOR FRAME JIG
This invention relates to a door frame jig.
In order to mount a door in a door frame it is generally necessary to mount a keep or latch plate to the door frame in order to receive a door latch or deadbolt of a door handle. The door frame is conventionally made of wood or MDF (medium-density fibreboard) and the wood or MDF can split when material is being removed, for example with a chisel, in order to allow the keep or latch plate to be fitted.
It is therefore an object of the present invention to provide a doorframe jig which allows material to be removed from a door frame in order for a keep or latch plate to be fitted and which eliminates, or at least substantially reduces, the risk of the material of the frame splitting.
According to one aspect of the present invention there is provided a door frame jig comprising a component formed with an aperture within the periphery thereof, which aperture is open at the periphery thereof by way of a passage, the aperture and passage having a configuration to permit a latch plate to pass therethrough, and a further component having an external profile to fit within the aperture and to key therewith, the further component being formed with an aperture within the periphery thereof.
-2According to another aspect of the present invention there is provided a door frame jig comprising:
a first component formed with a first aperture within the periphery of the first 5 component, which first aperture is open at the periphery of the first component by way of a first passage;
at least one second component having an external profile to fit within the first aperture and first passage of the first component and to key therewith, the second component being formed with a second aperture within the periphery of the second component, which second aperture is open by way of a second passage at a periphery of the second component in the region of the first passage such that the second passage passes through the first passage and opens at a periphery of the first component; and at least one third component having an external profile to fit within the first aperture of the first component and to key therewith, the third component being formed with a third aperture within the periphery of the third component.
The first component may have a substantially rectangular external profile and may be provided with a plurality of countersunk openings adjacent to a long side of the rectangular profile. An elongate line may be provided, for example scored into the surface of the first component, running parallel to the openings and/or a longitudinal edge of the first component.
-3A further elongate line may be provided parallel to the first-mentioned elongate line described above. Further countersunk openings may be provided along a line substantially parallel to the first-mentioned countersunk openings.
The first aperture may be substantially rectangular. The first passage may have parallel sides and may be positioned such that a mid-point of the first passage corresponds substantially to the mid-point of the first aperture.
The first component may be provided with a first line, for example scored into the 10 surface of the first component, which extends transversely across the first component, at least on that side of the first component remote from the first passage, and may be aligned with a centre line of the first passage. A second line may extend parallel to the first line. A third line may also extend parallel to the first line on an opposite side of the first line to the second line.
The second aperture may be substantially rectangular.
The second component may also be provided with first, second and third lines, at least on that side of the second component remote from the second passage.
The third component may have an external profile to fit within the first aperture and the first passage of the first component.
The third aperture may be substantially rectangular.
-4The third component may be provided with first, second and third lines on both longitudinal sides of the third component.
The third aperture may be dimensioned so as to be smaller than and to fit 5 entirely within the second aperture.
The first, second and third components may be made of any suitable material such as a sheet plastics material, for example a transparent or translucent plastics material such as an acrylic.
The jig may be provided, or formed, with a permanent lip extending at right angles to the first component, the lip being formed with a recess, for example extending beyond the edges of the second passage.
The jig may include a plurality of each of the second and third components.
For a better understanding of the present invention and to show more clearly how it may be carried into effect reference will now be made, byway of example, to the accompanying drawings in which:
Figure 1 is a plan view of a first embodiment of a first component of a doorframe jig according to the present invention;
-5Figure 2 is a plan view of a first embodiment of a second component of a door frame jig according to the present invention, the second component being used in conjunction with the first component;
Figure 3 is a plan view of a second embodiment of a second component of a doorframe jig according to the present invention;
Figure 4 is a plan view of a first embodiment of a third component of a door frame jig according to the present invention, the third component being used in conjunction with the first component;
Figure 5 is a plan view of a second embodiment of a third component of a door frame jig according to the present invention; and
Figure 6 illustrates part of an alternative embodiment of a door frame jig according to the present invention.
The first component 1 of the door frame jig according to the present invention shown in Figure 1 is intended for use with a wooden batten, for example about
22mm x 44mm x 400mm, which is not shown in Figure 1. To this end the first component has a substantially rectangular external profile and is provided with a plurality of countersunk openings 3 adjacent to a long side of the rectangular profile in order that the first component can be secured to the wooden batten, for example the narrow (22mm) face thereof, with the aid of screws or the like (not
-6shown). For example, an elongate line 4, which may be scored into the surface of the first component, may run parallel to the openings 3 and can be aligned with an edge of the batten. In practice the batten is sacrificial and can be replaced as necessary.
The first component is formed with a substantially rectangular first aperture 5 within the periphery of the rectangular profile, which aperture is open at the periphery of the rectangular profile by way of a first passage 7. The first passage 7 has parallel sides and is generally positioned such that a mid-point of the first passage 7 corresponds substantially to the mid-point of the first aperture 5. It will be noted that it is not essential for the first aperture 5 to be rectangular, but that only the profile of the first aperture 5 corresponds to the external profile of the second and third components such that the second and third components can key with the first aperture and be retained therein. The first component is provided with a first line 9, for example scored into the surface of the first component, which extends transversely across the first component, at least on that side of the first component remote from the first passage 7, and is aligned with a centre line of the first passage 7. A second line 11 extends parallel to the first line 9 and is positioned about 28mm above the first line, while a third line 13 also extends parallel to the first line, but is positioned about 28mm below the first line. The first component may, for example, have a width of about 95mm and a height of about 275mm. The openings 3 may be provided about 22.5mm and 67.5mm from the upper and lower edges and about 10mm from the longitudinal edge. The line 4 may be positioned about 20mm from the
-7 longitudinal edge of the first component. The first aperture may have a width of about 40mm and a height of about 138mm, while the first passage may have a height of about 95mm and a length of about 25mm to space the edge of the first aperture at that distance from the longitudinal edge of the first component.
The first embodiment of the second component 15 shown in Figure 2 has an external profile to fit within the first aperture 5 and first passage 7 of the first component 1 and to key therewith such that the second component remains stationary within the first component during use of the jig. The second component 15 is formed with a substantially rectangular second aperture 17 within the periphery of the second component, which second aperture is open by way of a second passage 19 at a periphery of the second component in the region of the first passage 7 such that the second passage passes through the first passage and opens at a periphery of the first component. The second component may also be provided with first, second and third lines 21,23 and 25, respectively, at least on that side of the second component remote from the second passage 19, but also on that side adjacent to the second passage where feasible.
The second aperture 17 and second passage 19 are dimensioned to receive a keep and striker plate and alternative second components 15, such as that shown in Figure 3, can be substituted for the second component of Figure 2 in dependence upon the configuration of the keep and striker plate to be installed in the door frame. The second component is dimensioned to fit within the first
-8component and therefore has an overall height of about 138mm and an overall width of about 65mm. In the second component shown in Figure 2, the second aperture has a height of about 80mm and a width of about 29mm, while the second passage has a height of about 40mm and a length of about 27mm. In
Figure 3, the second aperture has a height of about 118mm and a width of about 28mm, while the second passage has a height of about 74mm and a length of about 26mm.
The third component 27 replaces the second component 15 during part of a procedure employing the jig as will be explained hereinafter. The first embodiment of the third component 27 has an external profile to fit within the first aperture 5, and optionally the first passage 7, of the first component 1 and to key therewith such that the third component remains stationary within the first component during use of the jig. The third component 27 is formed with a substantially rectangular third aperture 29 within the periphery of the third component. Portions of the third component 27 entirely surround the third aperture 29. The third component may also be provided with first, second and third lines 31, 33 and 35, respectively, on both longitudinal sides of the third component. The third aperture may be dimensioned so as to be smaller than and to fit entirely within the second aperture. The third component is also dimensioned to fit within the first component and therefore has an overall height of about 138mm and an overall width of about 65mm. In the third component shown in Figure 4, the third aperture has a height of about 56mm and a width of
-9about 24mm. In Figure 5, the third aperture has a height of about 86mm and a width of about 25mm.
The first, second and third components of the door frame jig according to the 5 present invention may be made of any suitable material such as a sheet plastics material, ideally a transparent or translucent plastics material such as an acrylic.
In use of the door frame jig according to the present invention, the first component 1, with the batten attached, is clamped to the door frame with conventional removable clamps (not shown) at a required elevation and the correct location within the frame. The elongate line 4 positions the batten at a desired location within the frame such that the door will be flush with the frame when the door is closed. The transverse lines 9, 11, 13, 21, 23, 25, 31, 33, 35 facilitate positioning the jig at a desired elevation, for example the first line or 15 lines are conventionally at a height of 1 m above floor level. The first lines are intended for use with most doors, that is those with only a single door latch. The keep or latch plate for a door handle with a single door latch is compatible with the second component shown in Figure 2 and with the third component shown in Figure 4. In this case the latch plate has a relatively smaller vertical extent and the vertical extent of the second and third apertures in the second and third components is correspondingly smaller. A bathroom door handle, for example, may be provided with a second door latch in order to lock the door and the keep or latch plate for a door handle with two door latches is compatible with the second component shown in Figure 3 and with the third component shown in
-10Figure 5. In this case the latch plate has a relatively larger vertical extent and the vertical extent of the second and third apertures in the second and third components is relatively larger. In order to maintain the door handle at a consistent height, the upper of the second or third lines is conventionally at a height of 1 m above floor level. Both second and third lines are provided to allow the jig to be inverted depending on which way the door opens (or is hung).
Once the first component has been clamped to the door frame in the desired location, the appropriate second component is inserted in the first aperture 5 and first passage 7 and the jig is ready for a first phase in conjunction with a router. If desired, the second component can be inserted in the first aperture and first passage before the jig is clamped to the door frame.
The router is provided with a suitable guide bush and plunge bit, for example a
23.8mm diameter guide bush and a 20mm diameter plunge bit, and the router is set to the correct depth for the keep or latch plate being used. The router is then used to remove material within the area defined by the second component and to a first depth determined by the plunge bit. In so doing, the router may also remove material from the batten where the second passage 19 passes over the batten.
Once the area defined by the second component has been routed to the first depth, the second component is removed from the first component and the
-11 appropriate third component is inserted in the first aperture 5 and first passage 7 and the jig is ready for a second phase with the router.
The plunge bit of the router is adjusted to the correct depth for the second phase 5 in order to receive the door latch or bolt and/or a back box of the keep or latch plate, the second depth being greater than the first depth. The router is then used to remove material within the area defined by the third component and to the second depth as determined by the plunge bit.
The jig can then be unclamped and removed from the doorframe and any edges that need to be tidied or any corners that need to be squared can be modified by hand, for example with a chisel or edging chisel. The keep or latch plate can then be fastened in position in the conventional manner.
There is no need to remove and replace the jig during use, only to substitute the third component for the second component as appropriate, thereby saving time and effort, while producing a reliable and accurate rebate for mounting the keep or latch plate.
It is convenient to use the jig mounted to a wooden batten, for example because there is minimal risk of damaging the router plunge bit when passing through the second passage 19 and because it is easy to dismantle the jig from the batten in order to store the jig in a substantially flat configuration when it is not required. However, as shown in Figure 6, the first component of the door frame jig may
-12 alternatively be provided, or formed, with a permanent lip 37 extending at right angles to the first component, the lip being formed with a recess 39 extending beyond the edges of the first and/or second passage 7, 19 to ensure the router plunge bit does not contact the lip 37 as it passes into or out of the second passage. Such an arrangement precludes any errors of alignment when securing the first component to a batten.
The door frame jig according to the present invention may be modified in a number of ways. Although only two sets of second and third components have been described, clearly further sets of second and third components may be provided to extend the range of latch plates and keeps that can be accommodated. The jig can be adapted for use with thicker doors (in which the latch or bolt would be positioned differently) by providing a second elongate line 4, parallel to the elongate line described above, and, if appropriate, additional openings 3 to enable the first component 1 to be positioned appropriately on a batten to accommodate the different position of the latch plate or keep. Although the jig has been shown in the drawings as comprising first, second and third components, it is only essential to provide two components, an outer component which is in effect a combination of the first and second components described above in relation to the drawings in order to provide an aperture and passage to permit the door frame to be routed to remove sufficient material to the removed to a first depth to receive the latch plate or keep, and a further component which engages within and is keyed to the aperture, and optionally the passage, and which is formed with an aperture having dimensions which allow
-13a further amount of material to be removed to a second depth to receive the door latch or bolt and/or a back box of the keep or latch plate. Such a door frame jig is simpler and more cost effective to manufacture, but can only be used with a restricted range of keeps or latch plates.
