Abstract

A jig for hanging hinged elements such as doors and windows comprises an upright member 1 to which a cross member 2 is pivotally connected. Three hinge templates (4, 5, 6, figure 1) are adjustably spaced along the upright member 1. Both members 1, 2 are adjustable in length to cater for different sized elements. In use, the jig is first offered up to the element frame and the position of the hinges is marked using the hinge templates (4, 5, 6, figure 1), the cross member 2 is then aligned with the head of the frame, the jig is then removed and offered up to the element marking the corresponding hinge and head positions or element, finally the hinges may be fixed to the element and the element offered to the frame fixing the hinges in the previously marked positions on the fame.

Description

A JIG The present invention relates to a jig. The jig is intended

particularly, but not exclusively, to hang doors.

In old houses, and sometimes in new houses, the top of the 5 doorframe (the head) is often out of square with the remainder of the frame. This leads to irregular gaps between door and frame. It is possible to adjust and shape the door to compensate for this irregularity but doing so can be tedious and expensive requiring a number of different sequential operations in which the door is repeatedly altered and then tried for fit in 10 the doorframe. Even in frames which are square positioning the hinge so that the door can be correctly hung on the frame can be a lengthy and repetitive process. It is an object of the invention to mitigate these disadvantages. According to the present invention, there is provided a jig for use in 15 hanging a hinged element such as a door, window, or the like comprising a member, adapted in use to be aligned with an upright edge of the element and frame in which the element is to be mounted, and at least one hinge template connected to the first member adapted in use to facilitate positioning of one or more hinges on the element and frame and 20 hanging of the element on the frame.

The jig may be moulded advantageously from a single piece of material. In a preferred embodiment of the invention there are three or four hinge templates disposed at spaced intervals along the member. The or

each hinge template is dimensioned to provide for two or more hinge sizes and may be adjustable in position on the member. The two hinge sizes may be three and four inches or their metric equivalents. Another member may be provided pivotally connected to the first mentioned 5 member adapted in use to be aligned with an edge of the element and frame transverse to the upright edge. The members are pivotally connected together through a screw which may be tightened to fix the members together in a desired relative angular position. This relative angular position, in use, is determined by the angle of the cross member or lintel of the frame to the upright of the frame. The jig comprises a clearance plate, the thickness of which, in use, determines the gap between the undersurface of the cross member of the frame and the adjacent upper surface of the door to be mounted in the frame. The clearance plate is moveably connected to the member for movement 15 between first and second positions in which the jig is used respectively on oppositely facing upright members of a doorframe. The moveable connection may allow sliding or pivotal movement or a combination of the two. The other member is also adjustable in length for doors and doorframes of different width. A cross brace may be connected between 20 the first and second members. Each end of the brace is disposed to run in slots formed respectively in the first and second members and to be connected thereto by screws which may be tightened and untightened to fix and release the cross brace in and from the fixed position. Adjustable telescopic sections are provided at opposite ends respectively of the

member enabling the height of that member to be adjusted for elements of differing height. Stops are provided to limit the movement of the sections with respect to the member. The other member and telescopic section remote from the other member may be interchanged so that the 5 jig may be used on an element opening in the opposite direction. The jig may be made from metal such as aluminium or moulded from plastics material. In order that the invention may be more fully understood, one embodiment thereof, will now be described by way of example with to reference to the accompanying drawings, in which: Figure 1 is a partial side elevational view of a jig, Figure 2 is a front elevational view of part of the jig of Figure 1, Figure 3 is a plan view of the jig of Figure 2, Figure 4 is a plan view of part of the jig of Figures 1 to 3 in position 15 against a door frame.

Figure 5 is a front elevational view of part of the jig of Figures 1 to 4 in position against a door.

Figure 6 is a side elevational view of part of the jig of Figures 1 to 5 in relation to a door frame.

20 Figure 7 is a cross section of part of the jig shown in Figure 6.

Figure 8 is a front elevational view of part of the jig of Figures 1 to 7, Figure 9 is a side elevational view of the jig part shown in Figure 8, and

Figure 10 is a partial cross-sectional view of a modification of the embodiment of Figure 1 to 9.

Referring to the drawings, the jig comprises a first upright member 1 and a second, cross member 2 pivotally connected to the upright 5 member 1 through a screwthreaded pivot 3. The jig is made from metal a preferably aluminium, although alternative materials such as plastics material may be used. In this latter case the jig may be moulded. Three hinge templates 4, 5 and 6 are adjustably spaced along the upright member 1. Each hinge template is disposed to slide in a respective slot in 10 the upright member and may be fixed in a chosen position by means for a corresponding manually adjustable knurled headed screw 7, 8 and 9.

Each hinge template is dimensioned so that its external dimension corresponds to a four inch hinge and its internal dimension to a three inch hinge. Other hinge dimensions may be provided for as desired. The 15 external and internal dimensions are referenced E and I on the hinge template 4 shown on Figure 6.

Adjustable telescopic sections 10 and 11 are provided at opposite ends respectively of the upright member 1. The sections 10, 11 are provided with respective height stops 12, 13, which limit their movement 20 from the member 1, and adjustable head screws 14, 15 which enable the corresponding section to be manually fixed in a chosen adjusted position.

The cross member 1 may be adjusted in length. For this purpose an extension 30 is provided at its free end which may be withdrawn from or retracted into the member 2 to increase or decrease its effective length to

cater for doors and doorframes of different width (see Figure 3). A supporting brace 16 (see Figure 2) connects the upright and cross members 1 and 2. Each end of the cross brace is mounted for slidable movement in a corresponding slot 17 and 18 in the upright and cross 5 members and may be fixed in a chosen adjusted position by corresponding adjusting screws 19 and 20. The arrangement is such that the cross brace 16 and cross member 2 may be pivoted in a clockwise direction until both are aligned with the upright member 1 to facilitate transportation. To further facilitate transportation the upright member 1 10 may be broken part way along its length and the two parts folded together, for example about a hinge. A tape measure may be provided along one or both of the upright and cross members. Each measure may extend along the whole or a part only of the length of the member. On the upright member, the measure may enable the position of the or each 15 hinge template to be measured. The or each measure may be in imperial or metric units and may be printed, impressed or embossed or the member or on a separate element attached to the member.

The jig is used to hang a door in a door frame in the following manner. With the door removed, the jig is offered up to the door frame.

20 The upright member 1 is aligned with the upright member 21 of the frame on which the hinges 27 are to be fixed. The cross-member 2 is adjusted by pivoting it until it is aligned with the cross head member of the frame 2. The cross-member is then fixed in that position in relation to the upright member by tightening screws 3, 19 and 20. The jig may be

connected to the door frame by means of a small screw through aperture 25 {see Figure 6). The height of the upright member and therefore of the cross member 2 may be set by adjusting the adjustable section 11 and fixing this section in the adjusted position by tightening the corresponding S screw 15. The hinge templates 4, 5 and 6 are set in from the surface of the upright member by an amount less than the distance the architrave 22 is set back from the door frame as shown at 23 on Figure 4.

After positioning the jig against the doorframe, the upper hinge template 4 is adjusted to the desired position on the upright member 1 10 and fixed in that position by tightening the corresponding screw 7. The position of the middle and lower hinge templates 5 and 6 may be similarly set and fixed by means of the corresponding screws 8 and 9. The positions of the hinges on the door frame may then be marked, for example, with a pencil. As mentioned previously, each template provides 15 for either a four inch or a three inch hinge and further different hinge sizes can be provided for by appropriate sizing and or formation of the hinge templates. The jig may then be removed from the doorframe and a hinge placed in each marked hinge position on the doorframe to enable screw positions to be marked and those positions pilot or predrilled as desired.

20 Where a replacement door is being fitted or existing door is simply being modified and the hinge positions are already marked on the doorframe, the hinge templates may simply be moved to the existing hinge positions.

An existing door may then be modified perhaps in the joiner's van or site using the jig and quickly replaced with minimum inconvenience,

The jig is then offered up to the door which is to be fitted on the doorframe. The head of the door is first checked with the jig by aligning the upright member 1 of the jig with the upright of the door and appropriately marking the head of the door using the cross member 2 of 5 the jig. The head of the door may then be shaped as required so that the upper edge of the door is at the same angle to the upright as the corresponding cross and upright members of the jig and therefore as the corresponding cross and upright members of the door frame. Shaping can be by planning or sawing or both. The door is also cut, for example by 10 saving, to the correct height. The upper plate of the cross member 2 through which the aperture 25 extends has a thickness which determines the gap between the undersurface of the top of the doorframe and the upper surface of the top of the door.

With the jig in position on the door as described above, the hinge 15 templates 4, 5 and 6 abut the edge of the upright of the door to which the hinges are to be connected. Using those templates the hinge positions are marked and material from the edge of the door removed as normal to accommodate the hinges after first removing the jig from the door. The hinges may then be fixed to the door in the marked positions 20 and the door with hinges attached offered up to the door frame to line up the door with the frame and the hinges with the corresponding marked hinge positions on the frame. The hinges are then fixed to the door frame in those marked positions to complete the job.

The jig may also be used to hang a door opening in the opposite direction from the other side of the door frame. To this end, the cross member 2 and adjustable height section at opposite ends respectively of the upright member 1 are interchanged.

In an alternative simplified embodiment, the cross member 2 may be dispensed with. The hinge templates are centrally located between opposing faces of the upright member as shown in partial cross sectional view in Figure 10 abutting a door frame 31. One hinge template is shown at 34 on an upright member 30 and opposing faces are referenced 35 and 10 36. The jig may then be moved to the opposite upright of a doorframe where an oppositely opening door is required. The clearance plate 37 pivotally connected to the top of the upright member 30 would be pivoted or rotated to extend in the opposite direction with respect to the upright 30 as indicated by arrow 38. In a further simplification, where the jig is 15 moulded from synthetic plastics material, the clearance plate would be moulded integrally with the remainder of the jig but movable between the two required opposing positions. The hinge templates may be non-

adjustable.

It will be appreciated that the above embodiments have been 20 described by way of example only and that many variations are possible without departing from the scope of the invention. For example, the jig appropriately sized may be used to hang other opening members such as windows.
