Description

AN ESCUTCHEON FOR A DOOR, A DOOR FURNITURE KIT, AND A METHOD FOR MOUNTING AN ESCUTCHEON TO A DOOR Technical field The disclosure herein generally relates to an escutcheon for a door, a method for mounting an escutcheon to a door, and a door furniture kit.

Background Door furniture, for example escutcheons for door locks, door handles and the like, are generally attached to the face of a door with mechanical fasteners, for example screws. The heads of the mechanical fasteners are often externally visible and can be manipulated from at least one side of the door, for example the side of the door facing a building interior. Having the heads of the fasteners exposed on the interior facing side may be more secure, but it still enables tampering from within the building, which may be a security risk or enable an unqualified person access to the internals of the lock.

It may be desirable for locks to be tamper resistant from both sides of the door. Double cylinder bolts, for example, accept a key on both sides of a door to prevent unauthorised passage from either side, and so may benefit from being tamper resistant on both sides.

It may be aesthetically pleasing to have hidden escutcheon fasteners. It may also be desirable to have a lock with a readily replaceable escutcheon, for example when an escutcheon is damaged or no longer fashionable.

The escutcheon fasteners may be concealed by a shroud or aesthetic escutcheon. This requires an extra component increasing material and labour costs and may be easily vandalised, and may not satisfactorily address security.

Description of embodiments Figures 1 and 2 show a rear perspective view and an exploded rear perspective view respectively of an embodiment of an escutcheon for a door, the escutcheon being generally indicated by the numeral 10. In this but not all embodiments, the escutcheon 10 comprises a shell 12 defining at least one aperture 16,18 for disposing therein at least one of a bar connecting a handle to a lock in the form of a mortice lock and a lock cylinder coupled to the lock. Figures 3 and 4 shows a front perspective view and a front cut-away perspective view respectively of the another embodiment of an escutcheon 600 mounted to the door 20. The escutcheon 600 is similar to that of figures 1 and 2, where parts similar or identical in form and/or function are similarly numbered, wherein the lock cylinder 22 is disposed in aperture 18, and the handle 24 is attached to the bar which passes through aperture 16 to engage the lock 23 having a retractable and extendable bolt 25. Returning to figures 1 and 2, attached to the inside of the shell 12 is at least one fastening system. The fastening system 26 is configured to be fastened to a mounting part 28 in the form of a mounting head or mounting boss fixed to the door. Another embodiment has another fastening system spaced apart from fastening system 26 and configured to be fastened to another mounting head 30 in the form of another mounted boss fixed to the door 20 and vertically (or otherwise) spaced apart from mounting head 28. Figure 5 shows a detail of the fastening system 26 fastened to the mounting head 28.

The aperture 18 for disposing therein a lock cylinder (a “lock cylinder aperture”) is – in the embodiments of figures 1 - 4 by not necessarily in all embodiments – configured such that when the lock cylinder is disposed in the lock cylinder aperture the gap, if any, between the lock cylinder and the escutcheon 10 does not provide access for tampering. For example, the fit between the escutcheon and the lock cylinder may be a clearance fit or tighter.

The mounting heads 28,30 are each attached to the door 20 with a screw or bolt 45, the shaft of which is disposed in a central through hole defined by mounting heads 28,30. An axis in the form of a longitudinal axis of each of the mounting heads 28,30 is normal to the face of the door the mounting heads 28,30 are mounted to. The thread of the bolt may engage the door, a plate or nut disposed within the door 20, a plate or other escutcheon on the far side of the door, or generally any suitable part. A lock smith, for example, may drill holes into the door 20 for mounting the mounting heads 28,30. The escutcheon 10 has a front plate 50 comprising outward face 56 that when installed in the door 20 faces away from the door, and which defines the apertures 16,18. The escutcheon also comprises opposing lateral side walls, for example side wall 57, and opposing end walls, for example end wall 59. A perimeter wall comprises the side walls 57, end walls 59, and is attached to the perimeter of the front plate 50 at a base thereof to form the shell 12.

The fastening system 26 comprises hanging means 32 in the form of a hanger, which comprises a hook for hanging off the mounting head 28. The hanger 32 comprises a hanger plate 34 comprising spring metal in the form of spring steel. The hanger comprises a cradle 33 defining a cavity, however an alternative embodiment may comprise a cradle without hanging means, for example the cradle may be rotated 180 degrees so that the escutcheon cannot be hung. The hanger plate is received within a laterally opening cavity 36 in the form of a groove that is defined by the mounting head 28. In the present embodiment the groove 36 is circumferential, however it may not be. At the bottom of the groove 36 is an intermediate portion that is intermediate two flanges 40,42 which are at opposite ends of the mounting head 28, the intermediate portion and flanges 40,42 defining waist 38. The intermediate portion has a cylindrical cylinder configuration, however it may be convex or concave or generally have any suitable form. The opposite ends of the mounting head 28 define the longitudinal axis. The flanges 40,42 are parallel to the face 56 of the escutcheon 10, with the flange 42 closest to the face 56 having a diameter less than that of the flange 40 furthest from the face 56. The cradle 33 is configured to be laterally inserted between the flanges 40,42 at opposite ends of the mounting head 28 and have the cradle 33 receive the waist 38. The cavity defined by the cradle 33 is transversely smaller than the transverse extent of the flange 42. Engaging the waist 38 with the cradle 33 is generally achieved by disposing the shell 12 over the mounting head 28 and subsequently sliding the escutcheon on the face of the door 20 so that the hanging means 32 of the escutcheon 10 are received through the opening of cavity 18 and into the cavity defined by the waist 38. The escutcheon 10 cannot then be pulled away from the face of the door 20 without first sliding it out of engagement with the mounting head 28. The waist 38 and the flanges 40,42 are integral. The flanges 40,42 and waist 38 may alternatively be separable parts threaded onto fastener 45 in the form of a screw or bolt, which may have a driving tool engagable head, for example a Philips head. The hanger 34 plate biases the side walls 59, 57 towards the door 20 to prevent the escutcheon rattling against the door 20. Alternative embodiments have an enlarged distal end rather than a flange 42. The flange 40 comprises a flat base and so is configured for mounting to the face 21 of door 20. The flange 40 may not have a flat base, but may be undercut to provide improved stability, or may have door face engaging feet. Flange 42 comprises major bevelled lateral surface 44. By providing a relatively broad surface in contact with the door 20, flange 40 stabilises the mounting head 28.

Generally, the base of the flange 40 may be configured in any suitable way for mounting to the face 21 of the door 20. In an alternative embodiment, the shell 12 does not hang on the mounting head 28. In one such alternative embodiment, for example, the orientation of the hanger 32 may be reversed, and in use the shell 12 may be lifted into engagement with the mounting head 12.

Figure 10 shows a detail from figure 1.

The fastening system 26 comprises a fastener 46 in the form of a screw, for example a grub screw, spaced apart from the hanger 32 to define a space for receiving the mounting head 28.

The tip of the fastener 46 is disposed in the space. The space is occupied by mounting head 28 in figure 5. The fastener 46 is operable to engage the mounting head 28 and pull the hanger 32 towards mounting head 28, overcoming the spring force exerted by the hanger 32 on the mounting head 28 and clamp the mounting head 28 to the hanger 32 when so received. The fastener 46 is in the form of a screw (in this but not all embodiments a grub screw), and has a driving tool engagable end 48. The fastener 46 has a mounting head engagement end 54 in the form of a tip that is opposite the driving tool engagable end 48 and that has a diameter greater than that of a shaft of the screw, preventing the screw from being accidentally wound out of the through hole. The driving tool engagable end 48 has a hexagonal socket for engaging with a hex key, however it may have a slot for engaging with the tip of a slot head screwdriver, a hex head for engaging with a hex socket, or generally be configured for engaging any suitable form of driving tool. The fastener 46 is arranged for the driving tool engagable end 48 to be accessible to a tool inserted through an aperture of the at least one aperture 16,18. In the present embodiment, the fastener 46 is accessible with a long Allen key via aperture 18 (which is a lock cylinder mounting aperture) to tighten the escutcheon to the aluminium extrusion that forms the perimeter of the door 20 or the door shell. The flange 42 of the mounting head 28 is chamfered to provide superior engagement with the obliquely orientated fastener 46. In alternative embodiments, the fastener may be parallel or at right angles to the face 56 of the shell 12.

In this but not all embodiments, the fastener 46 can only be tightened or loosened or manipulated by accessing it through the lock cylinder mounting aperture 18. Once the fastener 46 is tightened the lock cylinder 22 is fitted into the lock cylinder mounting aperture 18, as shows in figure 6. The lock cylinder 22 is retained in place using a cylinder pin 61 only accessible from the door edge 63 through which the lock bolt 25 moves, as shown in figure 7. The pin 61 is received within a lock cylinder pin aperture 27. When fastened in place, the lock cylinder 22 blocks sliding disengagement of the escutcheon from the mounting head 28, and subsequently removal from the door 20. That is, the lock cylinder 22 may also be a stop. The inner edge of the lock cylinder mounting aperture 18 comprises a stop receiver 19 for receiving the lock cylinder, and so preventing sliding disengagement of the escutcheon 10 from the mounting head 28. In the case that a euro lock cylinder is used, a screw in the form of a centre screw may be used to fasten the euro lock cylinder, for example. Alternatively, a Scandinavian oval lock cylinder may be used, and appropriate means for fastening may be used. Mortice cover plate 65 may be disposed at the edge of the door and over the opening of the mortice formed in the edge of the door 20 in which the mortice lock 23 is disposed. Fasteners in the form or screw, rivets, or generally any suitable fastener may fasten the mortice cover plate 65 to the door. Once the lock cylinder 22 is fastened, the fastener 46 cannot be accessed. In turn, the lock cylinder 22 cannot be removed when the door is shut because the cylinder pin cannot be removed, and so the escutcheon 10 is as secure as the lock cylinder 22. The escutcheon 10 cannot be removed to aid manipulation of the lock, and provides barrier protection for the lock 23. That is, the escutcheon cannot be unmounted without the door being open. In the context of this document, the meaning of unmounting and removal does not encompass brute-force breaking of fasteners or other parts of the door furniture kit or door to which the escutcheon is mounted to.

Clamped by at least one other screw 52 between the hanger 32 and the front plate 50 of shell 12 is a fastener attachment plate 54, however in an alternative embodiment fastener attachment means are integral to the shell 12. The fastener 46 is engaged with threaded walls of the fastener attachment plate 54 defining a through hole. The threaded walls enable the fastener 46 to be screwed inward and outward. The fastener attachment plate 54 is bent to form a tag 58 oblique to the face 56 of the shell 12, however in an alternative embodiment the tag 58 is not oblique to the face of the shell 12. The fastener 46 is oblique to a face 56 of the shell 12 such that the driving tool engagable end 48 is orientated towards the aperture 18, facilitating driving tool engagement.

The fastener 46 is configured to be clear of the aperture 18 when engaged with mounting head 28. The through-hole in which fastener 46 is disposed is perpendicular to a face of the tag 58, however in an alternative embodiment the through-hole may be oblique to the fastener attachment plate 58 rather than the having an out-of-plane tag 58. The fastener 46 may take generally any suitable form, for example a round pin that makes an interference fit through through-hole. Alternatively, an adhesive may be used to fasten the hanger 32 to the mounting head 28.

Escutcheon 600 of figures 3-4 has another hanger 60 in the form of a hook for hanging off another mounting head 30. The other hanger 60 also comprises a hanger plate comprising spring metal in the form of spring steel. The hanger plate is received within a groove defined by the other mounting head 30. The mounting head 30 is identical to mounting head 28, however in another embodiment it may have a different configuration. In the embodiment of figures 3-4, there is no fastener to clamp the other mounting head 30 to the other hanger 60 because there are no appropriate apertures for driving tool access, however another embodiment may have another fastener to clamp the other mounting head 30 to the other hanger 60, and may have another aperture for driving tool access to the other fastener. The other hanger may be, for example, adjacent aperture 16.Returning to escutcheon 10 of figures 1-2, the shell 12 comprises cast metal in the form of cast zinc alloy, however brass or any suitable metal may be used. Fastener engaging features and other structures may be integrally formed with the shell. Alternative embodiments may comprise fibre reinforced polymer. Alternatively, the shell 12 may be forged or machined.

It will be appreciated that embodiments may be provided in the form of a door furniture kit. The door furniture kit may comprise the escutcheon 10 for a lock for a door, and at least one (for example 2) mounting head configured to be mounted to the door and when so mounted have fastened thereto the escutcheon.

Embodiments may be used when there is no lock cylinder, for example installed on a door having a dead-latching latch. The lock cylinder may be replaced with a part having a similarly or dissimilarly configured exterior, for example, but without the key operated mechanism (a “dummy lock cylinder”) that extends into the door, and that is similarly fastened in place by a door edge accessible pin or another suitable fastener.

Figures 8 and 9 shows front and rear elevational views of another embodiment of an escutcheon 100 for a door, where parts similar or identical in form and/or function to those in figures 1 to 7 are similarly numbered.

Figures 11 and 12 show a rear perspective view and an exploded rear perspective view respectively of another embodiment of an escutcheon 200 for a door, where parts similar or identical in form and/or function to those in figures 1 to 7 are similarly numbered. The escutcheon 200 has an elongated boss 202 at the inside face 204 where an aperture for a lock cylinder may otherwise be present. The elongated boss 202 comprises an internal thread on internal walls defining aperture 208 for an interference member 206 in the form of a fastener, specifically a screw, that can be adjusted in and out of the elongated boss 202. The screw 206 may be adjusted for different door thicknesses, for example. In an alternative embodiment, the interference member may be integral with the shell or non-removable, in which case the internal thread on the internal walls defining aperture 208 may not be required.. Figures 13 - 15 show the escutcheon 200 being mounted to the door 20. In figure 13, the escutcheon 200 is placed in contact against the door 20, but is 2-3 mm vertical above its final installed position, waiting to be hooked behind the mounting heads 28,30. The pin 61 is out, and the securing screw 206 is slack.

The elongated boss 202 and screw 206 protrude into the aperture 212 for a lock cylinder 212 formed in door 20. The escutcheon 200 is not laterally restrained. In figure 14, the securing screw 206 is tightened, sliding the escutcheon 200 onto the mounting bosses 28,30 engaging hanging means 32. The elongated boss 202 and the screw 206 protrude into the cylinder aperture 212 in the door 20 and into a cylinder aperture formed within the lock mechanism. In figure 15, the cylinder pin 61 has been received, and is orientated transverse to the screw 206 and is adjacent to it, preventing a longitudinal movement by interference with the securing screw 206 and subsequent disengagement of the escutcheon 200 even when the screw 206 is removed.

That is, the cylinder pin 61 may also be a stop.

Figures 16 and 17 show a rear perspective view and an exploded rear perspective view respectively of another embodiment of an escutcheon 300 for a door, where parts similar or identical in form and/or function to those in figures 1 to 7 are similarly numbered. The escutcheon 300 has a mounting pad 306 at the inside face 304 where an aperture for a cylinder may otherwise be present. Fastened to the mounting pad 306 is a ramp structure 308, which may be separated from the mounting pad by at least one packer 309 as appropriate for the door thickness. Figures 18 and 19 show the escutcheon 300 being mounted to the door 20. The escutcheon 300 is placed in contact against the door 20, but is 2-3 mm vertical above its final installed position, waiting to be hooked behind the mounting heads 28,30. The ramp structure 306 protrudes into the cylinder aperture 312 formed in the door 20, but may not be laterally restrained. Figure 19 shows screw pin 314 screwed into the lock mechanism 318, and has moved across the ramp structure 306, and in so doing so has driven the ramp structure laterally relative to the screw pin 314 to slide the escutcheon 300 into engagement with the mounting heads 28,30. The screw pin 314 may also be a stop that when engaged by the ramp structure 306 prevents disengagement of the escutcheon 300 from the mounting heads 28,30.

Figures 20 to 25 show aspects of another embodiment of an escutcheon 400 for a door 20. Parts similar or identical in form and/or function to those in figures 1 to 7 are similarly numbered. As shown in figure 20, the escutcheon 400 comprises an internal stop engager 402 in the form of a flange. The escutcheon 400 is placed in contact against the door 20, but is 2-3 mm vertical above its final installed position, waiting to be hooked behind the mounting heads 28,30. A securing screw 404 is disengaged; the securing screw 404 is also a stop when fastened. The door defines two apertures 406,408 formed in adjacent faces of the door 20 for the securing screw 404 and a securing screw tool. As shown in figure 21, another securing screw 410 has been tightened, causing the escutcheon to slide into engagement with the mounting heads 28,30. The internal stop engager 402 is moved below the security screw hole 408. Figure 22 shows a plan view revealing a threaded member 410, in the form of a threaded triangular member, disposed within the door 20, and ready to receive screw 404. The threaded member 410 is for mounting the security screw 404 inside the door frame/extrusion. Figures 23 and 24 show the security screw 404 received by the threaded member 410 and disposed in the door 20 and positioned for engagement with the internal stop 402 engager, preventing disengagement of the escutcheon 400 from the mounting heads 28,30 even when securing screw 404 is loosened. Figure 25 is a side elevational view corresponding to figures 23 and 24, with the door 20 and a sidewall of the escutcheon shown transparently.

Figure 26 shows an exploded perspective view of the escutcheon 10 mounted to the door 20 and having attached thereto a short lever handle 700 using an optional plate 62. The plate 62 is intermediate the door 20 and the escutcheon 10. In the present but not all embodiments, the plate 62 is on the door 20 and the escutcheon 10 is on the plate 62. Spacing means may be disposed between the plate 62 and each of the door 20 and the escutcheon 10. The plate 62 may reduce the sliding friction experienced by the escutcheon 10 when, for example, it is slid into engagement with the mounting heads 28,30 during installation of the escutcheon 10. The plate 62 may protect the door, by reducing or preventing damage to the surface of the door 20. The plate 62 both reduces friction and protects the door 20, however in other embodiments pate 20 may do one or neither of these. The plate 62 comprises polished steel, however it may comprise generally any suitable metal for example aluminium, any suitable polymer for example nylon, or generally any suitable material. The material may be processed to reduce the sliding coefficient of friction, for example polished or polymer coated.

The steps of an embodiment of a method for mounting an escutcheon 10 disclosed herein to a door 20 will now be described. In a step of the method, at least one mounting head 28 is mounted to a face of a door 20. In a step, the at least one mounting head 28 so mounted is received within the escutcheon 10. In a step, the escutcheon 10 is moved in a lateral mounting head direction to engage the escutcheon 10 with the mounting head.

Generally, the lateral mounting head direction may be parallel to the face of the door, and may be also be a longitudinal escutcheon direction. In the case of circular mounting bosses, a lateral mounting head direction may be any direction perpendicular to the longitudinal axis of the circular mounting heads, which in the present embodiments is along central aperture of the mounting heads.

Some embodiments of the method may comprise engaging a stop mounted at the door 20 with the escutcheon 10 and so prevent movement of the escutcheon 10 in a counter head, whereby disengagement of the escutcheon 10 from the at least one mounting head 28 is prevented. In the disclosed embodiments, the stop may variously take the form of, for example, a lock cylinder, a lock cylinder pin, a screw, a screw pin, however the stop may generally have any suitable form.

Now that embodiments have been described, it will be appreciated that some embodiments have some of the following advantages: • Embodiments may have no externally accessible or visible fasteners, and may have improved tamper resistance, especially when the door is locked shut.

• Vandalism is less likely.

• It may be harder to drill the case of the lock and subsequently manipulate the internal lock mechanism for unlocking because the escutcheon cannot not be easily removed.

• The escutcheon fasteners do not pass through the lock, simplifying installation.

• An escutcheon may be installed on only one side of the door.

Variations and/or modifications may be made to the embodiments described without departing from the spirit or ambit of the invention. For example, while apertures 16 and 18 are respectively a round aperture for a rotatably mounted bar and an oval-ended slot for an oval shaped lock cylinder, they may generally take any suitable shape, for example oblong or hexagonal. The mounting head may comprise a boss, knob, or generally any suitable protuberance projecting from the door. Additionally, or alternatively, to the hanger plate, a hanger may comprise a pin that is received within an aperture of a mounting head. The cylinder portion is a circular cylinder, however it may be a rectangular cylinder, or some other shape. The mounting heads may be on, for example attached to, or integral to, the escutcheon and the hanging means mounted to the door. The pin used to retain the stop may alternatively be a screw or generally any suitable form of stop retainer. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive. Reference to a feature disclosed herein does not mean that all embodiments must include the feature.

Prior art, if any, described herein is not to be taken as an admission that the prior art forms part of the common general knowledge in any jurisdiction.

In the claims which follow and in the preceding description of the invention, except where the context requires otherwise due to express language or necessary implication, the word “comprise” or variations such as “comprises" or “comprising" is used in an inclusive sense, that is to specify the presence of the stated features but not to preclude the presence or addition of further features in various embodiments of the invention.
