Description

DEVICE FOR USE IN HANGING A DOOR

The present invention relates to devices for use in hanging doors. Devices according to the invention are particularly suitable for solving a problem of forming the hinge recesses in a door frame at locations to match those of respective hinges on a door to be hung and to provide a desired spacing between the top or bottom of the door and the door frame or an adjacent floor surface.

According to the present invention there is provided a device for use in hanging a door, the device comprising a rigid elongate element having adjacent one end a first stop surface facing the opposite end of the element and a second stop surface facing in the opposite direction to the first stop surface and spaced a distance therefrom and, spaced-apart along the element, a plurality of markers, the markers having means for selective positioning of each marker along the elongate element.

The device can be used to transfer the spacings between the hinge locations from a door to a door frame defining an opening in which the door is to be hung. This is done by placing the device along the hinge edge of the door, contacting the first stop surface with the top or bottom of the door, and adjusting the positions of the markers on the element so that each is aligned with a respective hinge or hinge location on the door edge. To ensure that, when the door is hung, there is a desired spacing between the top or bottom of the door and the door frame or an adjacent floor surface, the element is placed in the door opening to extend down or up the hinge side of the frame with the second stop surface contacting with the upper cross-member of the frame or the floor, respectively. The locations for the hinge recesses on the door frame can then be transferred onto the frame from the spaced-apart markers and the recesses for the hinges cut appropriately in the door frame. On hanging of the door, the door will be located by the desired spacing from the top or the bottom of the door opening.

Preferably, the first and second stop surfaces are provided by opposed surfaces of a stop member which is mounted on the elongate element for movement between a first, retracted position and a second, operative position.

Advantageously, the stop member is moveable between its first position and first and second alternative operative positions.

Conveniently, the stop member is slidably mounted on the elongate element.

Preferably, the stop member is slidably mounted on one end of the elongate element.

Advantageously, the stop member is formed in a plurality of pieces which can be mounted and demounted to change the said distance between the first and second stop surfaces.

Conveniently, each marker is slidable in a guideway extending longitudinally of the elongate element.

The markers advantageously have means for their locking in a desired position relative to the elongate element.

The locking means conveniently comprise a locking screw or a twist-lock device.

The markers may slide in a single guideway, for example a longitudinal slot in the elongate element, or each may be provided with a respective separate guideway extending over a part of the length of the elongate element.

Conveniently, the elongate element is formed in a plurality of sections, so that the device can be placed in a more compact condition for transportation and storage, means being provided for connection of the sections to place the device in a condition for use.

Preferably, the sections of the elongate element are linked together by connecting means.

Conveniently, each section of the elongate element has a respective marker thereon.

The device of the invention is conveniently provided as an accessory to a support block for holding a door in a vertical plane for working thereon, for example cutting out of the hinge recesses in its edge, the support block preferably having one or more slots into which the door can be placed and, preferably, also being provided with wedges for holding a door vertically and securely in one of the slots.

Conveniently, a device according to the invention and in its compact condition is located in a storage compartment in the base of the support block.

An embodiment of the invention will now be described by way of example, with reference to the drawings of this

specification, in which:

Figure 1 is a plan view of a device for use in hanging a door; Figure 2 is a section on the line Il-Il of figure 1; Figure 3 shows the device of figure 1 separated into three parts and showing also two connecting pieces; Figure 4 shows the device of figure 1 and a door support block in underneath perspective view; Figure 5 is a perspective view from above of the support block of figure 4; Figure 6 is a perspective view showing a door supported in the block of figures 4 and 5; Figure 7 is a perspective view showing a first stage of the use of the device; and Figure 8 is an elevation view of the device in use in a door frame.

The device shown in figure 1 consists of an elongate element 10 which is about 1.9 m long, 40 mm wide and about mm thick and formed, for example, from extruded aluminium alloy. The element is formed in three sections ba, lOb, lOc, each of which has a cross section as shown in figure 2. As will be evident from figure 2, the element 10 is formed with an undercut longitudinal slot 12 which has a narrower neck portion 14 opening into a wider portion 16.

There is a respective slot portion 12a, 12b, 12c in each element section bOa, lOb, lOc.

Within each slot portion 12a, 12b, 12c an adjustable marker element iSa, 18b, l8c is located. As will be seen most clearly from figure 2, each adjustable marker element 18 has a base 20 located in the wider slot portion 16, a threaded shank 22 which extends through the narrower neck portion 14 of the slot and a screw head 24 which is mounted on threads of the shank 22. The shank 22 carries a pointer element 26, through an opening in which the shank moves freely. The pointer element 26 has an elongated hexagonal shape, two opposite corners of which form pointers 26', 26".

The positions of the marker elements 18a, l8b, 18c can be adjusted along the length of the device by releasing and re-tightening of the respective screw heads 24 in order to position the elements at predetermined points along the length of the elongate element 10.

At one end of the element 10, there is a slidable stop plate 28 which is mounted for sliding movement in the directions of arrow A relative to the element 10 from a central position, as shown in figure 1, to either of two extended positions shown in dashed lines in figure 1 and indicated by reference numerals 28', 28". The face 30 of the stop plate 28 closest to the element 10 constitutes a first stop surface, the function of which is described hereinafter.

The opposite face 32 of the stop plate 28 constitutes a second stop surface, the function of which is also described hereinafter. The stop plate 28 is slidably mounted on the element 10 in any suitable manner and is provided with means, for example a locking screw or a click-stop arrangement, for its securement in either extended position.

The thickness of the stop plate 28 (corresponding to the distance between the first and second stop surfaces 30, 32) is chosen to be the same as the required spacing between the top edge of a door when hung and the lower surface of the top transverse member of the frame in which the door is hung.

This distance is typically 3 mm. If desired, the distance can be adjustable. This can be achieved by, for example, providing alternative demountable stop plates of different thicknesses, or by providing multi-part stop plates in the form of a plurality of skims which can be assembled to provide the desired thickness. The skims may be secured to one another by magnetic means.

As shown in figure 3 of the drawings, the three elements lOa, lOb, lOc of the device are joined by two joining elements 38a, 38b which are snugly received in the slot 12 and allow the three separate elements 10a, lOb, lOc to be assembled into a single piece.

Figure 4 of the drawings shows the device 10 assembled into a single piece but ready for disassembly and location in a storage compartment 40 in the bottom of a door support block 42 which is also shown in figure 5 of the drawings.

The support block 42 has two vertical slots 44a, 44b into which the edge of a door can be placed in order to hold the door in a vertical plane whilst work is carried out on the door edge which is uppermost. Wedges 46, on cords 48 to prevent their loss, are provided in order to secure the door securely in a selected slot 44a or 44b. The block 42 further has a hinged, lidded compartment 43 for screws, drills etc, a sharpening stone 45 and a loudspeaker 46 which can be linked to a dock for an item such as an iPod music player and associated electronic circuitry and power source.

The use of the device in the marking on a door frame with the locations of the three hinges on which a door is to be hung will now be described.

As shown in figure 6 of the drawings, the support block 42 is first placed on the floor and a door 50 located in one or other of the slots 44a, 44b in the block and wedged into a vertical position by a respective wedge 46, as shown in figure 6.

Hinge recesses 32 (see figure 7) can now be formed in the door at intervals measured along the length of the door, each hinge recess consisting of a shallow rectangular recess dimensioned to receive one leaf of a respective hinge. If the door has previously been hung, the hinge recesses, and possibly also the hinges, will already be present on the door edge.

Next, the device of the invention is used to transfer the locations of the hinges or hinge recesses to the appropriate jamb of the door frame. To do this, the stop plate 28 is slid into one of its extended positions 28', 28". The corresponding first stop surface 30 is then placed in contact with the top edge of the door 50, as shown in figure 7. The marker elements iSa, 18b, lSc are now each moved so that the respective pointer 26' or 26" points to a desired part of a respective hinge or hinge recess, preferably the end of the recess which will be uppermost when the door is hung.

Next, as shown is figure 8 of the drawings, the stop plate 28 is returned to its central position and the device positioned within a door frame 52, parallel to the hinge-side jamb 54 of the frame with the second stop surface of the stop plate in contact with the lower surface of the top transverse member 56 of the door frame. The markers 26a, 26b, 26c will now be positioned to correspond to the points along the hinge jamb 54 where the hinge recesses are to be formed. The recesses can then be cut in the frame and the door hung, when it will be at the predetermined spacing from the top transverse member of the frame.

Alternatively, the device can be used to measure from a datum level corresponding to the floor or threshold of the door opening and thereby leave a predetermined gap below the door when hung.
