Definitions

  • This invention relates to the field of lock assemblies.
  • the invention relates particularly, but not exclusively, to multipoint lock assemblies and to components for such assemblies.
  • a multipoint lock assembly comprising an elongate faceplate arrangement, a lockbox mounted on the faceplate arrangement, a first connecting rod linkage extending along the faceplate from the lockbox to a first remote gearbox, the first remote gearbox including a locking member that is movable by longitudinal movement of the first connecting rod between a locking position and a released position, the elongate faceplate arrangement being provided with a first opening and the first remote gearbox being mountable on the faceplate arrangement in a first position at which the locking member of the first remote gearbox is able to pass through the first opening at least in its locking position, wherein the elongate faceplate arrangement is further provided with a second opening longitudinally spaced from the first opening and the first remote gearbox is mountable on the faceplate arrangement in a second position, longitudinally spaced from the first position, at which the locking member of the first remote gearbox is able to pass through the second opening at least in its locking position.
  • first component of some kind that should not be understood as implying that there is necessarily a “second” component of the same kind, although there may be.
  • second component of the same kind, although there may be.
  • the assembly may, for example, be employed to secure a door or a window.
  • the assembly will usually be secured to a vertical edge of the door.
  • the assembly may be secured to either a vertical or a horizontal edge.
  • edge is to be regarded as the narrow face of the door between the two opposite main faces.
  • a connecting rod linkage is disposed immediately behind, but is freely slidable relative to, a faceplate arrangement and that is a preferred arrangement in the present invention. Whilst the linkage to the remote gearbox is commonly called a connecting "rod”, that should not be taken as implying any particular cross-sectional shape. Most commonly the “rod” is in the shape of a flat elongate bar.
  • the locking member of the first remote gearbox may take any of a wide variety of forms including locking bolts mounted for linear movement, chamfered latches and mushroom rollers; for most applications the locking member is preferably a hook latch.
  • the hook latch may be pivotally mounted in the gearbox and arranged to be rotated about its axis of pivoting by linear movement of the connecting rod.
  • the assembly further includes a blank for covering over the first or second opening.
  • a blank can be used to cover over any opening that is not receiving a remote gearbox.
  • Spring clips may be provided to retain the blank in the opening.
  • holes such as screw holes associated with the vacant opening, they may also be covered over or may be used to receive fastening screws.
  • the elongate faceplate arrangement preferably includes other formations in the region of each of the first and second openings for mounting the first remote gearbox. For example, holes for fasteners such as screws may be provided around the opening.
  • the present invention is able to be applied to such an arrangement.
  • the second remote gearbox is preferably of substantially the same construction as the first remote gearbox. More particularly, the arrangement of the second remote gearbox, the second connecting rod and the interaction of the elongate faceplate with those parts is preferably substantially the same as in the case of the first remote gearbox and the first connecting rod. That reduces the number of different parts required for the assembly.
  • the lockbox preferably includes a mechanism arranged to drive the first and second connecting rods simultaneously in opposite directions for driving the locking members of the first and second gearboxes.
  • Such mechanisms are known per se ; in the present case they are especially advantageous because the design of the remote gearboxes can then be simplified enabling them to be compact. Whilst it is conventional to drive the first and second gearboxes in both directions from the lockbox, it is possible for the drive to be in only one direction with resilient biasing in the gearboxes providing a drive in the opposite direction.
  • gearboxes may be connected in tandem to an appropriate connecting rod linkage. Any number of gearboxes may be connected and the number on one side of the lockbox need not be the same as the number on the other side.
  • multipoint assembly Whilst the multipoint assembly has been referred to as a multipoint lock assembly and reference has also been made to a lockbox, it should be understood that it is within the scope of the invention for the assembly to be, for example, manually actuated without any key or other access control.
  • the lockbox includes a key-operated locking device, for example a key-operated cylinder assembly.
  • the first connecting rod linkage, and the second linkage if provided, may comprise a single member extending between the lockbox and the gearbox, as is conventional. In that case it may be necessary to change the member or crop it if the position of the lockbox is changed.
  • the first connecting rod linkage includes a first link connected to a second link, the connection between the first and second links being able to be varied to adjust the combined length of the first and second links.
  • altering the length of a connecting rod linkage would have involved cropping of the linkage but in this arrangement that can be avoided, adding to the versatility and ease of adaption of the assembly to a particular application.
  • first connecting rod linkage including first and second links
  • inter-link connections of those links may also be variable.
  • the first and second links are preferably releasably coupled together via toothed formations, the combined length of the links being able to be adjusted by disengaging one toothed interengagement, moving one link longitudinally relative to the other and re-engaging another toothed interengagement. This enables the combined length of the links to be adjusted in a very simple manner.
  • One of the first and second links is preferably provided with an internally toothed block, the other of the first and second links being provided with an externally toothed part engaging teeth of the toothed block.
  • the externally toothed part is preferably of bar shape having a substantially rectangular cross-section and comprising opposite faces and opposite sides of substantially shorter width than the faces, at least one of the opposite sides being toothed.
  • both of the opposite sides of the externally toothed part are toothed.
  • the internally toothed block may of generally cuboidal shape and is preferably closed (but not necessarily completely covered over) on three sides and open on a fourth side. The opposite ends of the block are open to allow passage through the block of the link received in the block.
  • the opposite closed sides are preferably both toothed on their inside if both of the opposite sides of the externally toothed part are toothed, whereas only one of the opposite closed sides is preferably toothed if only one of the opposite sides of the externally toothed part are toothed.
  • the first link may be coupled at one end to the lockbox and may be generally in the shape of an elongate bar having a substantially rectangular cross-section and comprising opposite faces and opposite sides of substantially shorter width than the faces, the bar being orientated with the opposite faces of the bar substantially parallel to a front face of the faceplate arrangement.
  • a rectangular cross-section is conventional in multipoint locks where the depth of the lock is often restricted.
  • the first link is preferably cranked towards the end coupled to the lockbox to define a first portion of the first link between the lockbox and the crank and a second portion of the link between the crank and the second link, with the first portion of the link closer to the front face of the faceplate arrangement than the second portion of the link.
  • Such cranking of a link between the lockbox and the gearbox is a special feature of the assembly and is advantageous in allowing space for the engagement of the first and second links without causing the assembly to project too far forwards.
  • the elongate faceplate arrangement preferably includes a first plate extending over the lockbox, a second plate extending over the first remote gearbox and a third plate extending over a gap between the first and second plates.
  • a central lockbox with remote gearboxes on opposite sides of the lockbox there may be a second connecting rod linkage extending along the faceplate from the lockbox to a second remote gearbox on the opposite side of the lockbox from the first remote gearbox, the second remote gearbox including a locking member that is movable by longitudinal movement of the second connecting rod linkage between a locking position and a released position, wherein the second connecting rod linkage includes a third link connected to a fourth link, the connection between the third and fourth links being able to be varied to adjust the combined length of the third and fourth links.
  • the second connecting rod linkage is preferably of substantially the same construction as the first connecting rod linkage. That reduces the number of different parts required for the assembly.
  • the assembly further includes a mushroom roller locking member, the mushroom roller locking member comprising a locking head and a stem mounted on a connecting rod of the first connecting rod linkage, the stem extending from the locking head to a distal end, wherein a portion of the stem away from the distal end is provided with a screw thread engaging in a threaded hole of the connecting rod to couple the mushroom roller to the connecting rod to drive the mushroom roller when the connecting rod is driven and allowing the spacing of the locking head from the connecting rod to be adjusted.
  • a mushroom roller locking member comprising a locking head and a stem mounted on a connecting rod of the first connecting rod linkage, the stem extending from the locking head to a distal end, wherein a portion of the stem away from the distal end is provided with a screw thread engaging in a threaded hole of the connecting rod to couple the mushroom roller to the connecting rod to drive the mushroom roller when the connecting rod is driven and allowing the spacing of the locking head from the connecting rod to be adjusted.
  • the ability to adjust the spacing of the locking head of the mushroom roller from the connecting rod on which it is mounted can facilitate adjustment of the assembly to allow for tolerances or changes in relative positions of the lock assembly and a strike or keep. Thus, again the retrofitting of the assembly can be facilitated.
  • connecting rod referred to in the paragraph immediately above may be, but need not be, the first or second link of the connecting rod linkage described above.
  • a “mushroom roller” it should be understood that the kind of roller being referred to is one which has an upstanding stem extending forwardly from a front face of a multipoint lock assembly and a head on the end of the stem. Whilst the term “mushroom” is employed, that should not be taken as implying that the head is a mushroom shape. It could for example be of a non-circular cross-section and it need not be domed like a mushroom. Also, as will be understood, although the term used is “roller” the mushroom roller does not rotate during use; it is only rotated by an engineer to set the degree of projection of the head.
  • the mushroom head preferably has a formation facilitating its rotation by a tool.
  • the formation may comprise a slot across the outer end of the locking head, as in a construction described below. Such a slot can receive a screwdriver blade.
  • Other formations, for example to receive a hex key, may alternatively be adopted.
  • the threaded portion of the mushroom roller is preferably a high friction thread that inhibits rotation of the mushroom head during ordinary use.
  • the threaded portion of the mushroom roller may have a patch thread.
  • the distal end of the stem of the mushroom roller is unable to pass through the threaded opening in the connecting rod. In that way the mushroom roller can be retained on the connecting rod.
  • the distal end of the stem of the mushroom roller is riveted over to prevent it passing through the threaded opening in the connecting rod.
  • the distal end may be treated in some other way to achieve the same purpose.
  • the stem of the mushroom roller is preferably provided with a peripheral flange partway along its length, at least some of the portion of the stem between the peripheral flange and the distal end of the stem being threaded.
  • the elongate faceplate arrangement preferably has a slot through which the stem of the mushroom roller passes, the faceplate arrangement being located between the head of the mushroom roller and the connecting rod.
  • that flange is preferably disposed between the head of the mushroom roller and the faceplate arrangement and is preferably unable to pass through the slot in the elongate faceplate.
  • the assembly further includes a tab movably mounted in a first region on the faceplate arrangement and including in a second region an opening for receiving a fastener for securing the faceplate arrangement.
  • a tab is able to provide an alternative fastening point for a screw or the like and can be especially helpful where an existing potential fastening point for a conventional fastening has already been damaged.
  • the tab is preferably pivotally connected to the faceplate arrangement.
  • the tab may be pivotally connected by a rivet.
  • a secure fixing that allows mobility of the tab may be provided in that way.
  • the second region of the tab can be positioned to one side of the faceplate arrangement on which it is mounted and/or it can be positioned beyond an end of the faceplate arrangement on which it is mounted.
  • a plurality of tabs may be movably mounted in different regions of the faceplate arrangement. That can provide a more secure fixing and/or increase the number of potential fixing points available to a fitter.
  • a multipoint lock assembly comprises an elongate faceplate arrangement, a lockbox mounted on the faceplate arrangement, a first connecting rod linkage extending along the faceplate from the lockbox to a first remote gearbox, the first remote gearbox including a locking member that is movable by longitudinal movement of the first connecting rod linkage between a locking position and a released position, wherein the first connecting rod linkage includes a first link connected to a second link, the connection between the first and second links being able to be varied to adjust the combined length of the first and second links.
  • the first and second links may be releasably coupled together via toothed formations, the combined length of the links being able to be adjusted by disengaging one toothed interengagement, moving one link longitudinally relative to the other and re-engaging another toothed interengagement.
  • one of the first and second links is provided with an internally toothed block and the other of the first and second links is provided with an externally toothed part engaging teeth of the toothed block.
  • the externally toothed part may be of bar shape having a substantially rectangular cross-section and comprising opposite faces and opposite sides of substantially shorter width than the faces, at least one of the opposite sides being toothed.
  • Both of the opposite sides of the externally toothed part may be toothed.
  • the internally toothed block may be of generally cuboidal shape and be closed on three sides and open on a fourth side.
  • the first link may be coupled at one end to the lockbox and be generally in the shape of an elongate bar having a substantially rectangular cross-section and comprising opposite faces and opposite sides of substantially shorter width than the faces, the bar being orientated with the opposite faces of the bar substantially parallel to a front face of the faceplate arrangement.
  • the first link may be cranked towards the end coupled to the lockbox to define a first portion of the first link between the lockbox and the crank and a second portion of the link between the crank and the second link, with the first portion of the link closer to the front face of the faceplate arrangement than the second portion of the link.
  • the elongate faceplate arrangement may include a first plate extending over the lockbox, a second plate extending over the first remote gearbox and a third plate extending over a gap between the first and second plates.

  • the keep assembly is provided with an opening 38 for receiving the hook latch 18 when the gearbox is mounted in the opening 20 and with an opening 40 for receiving the hook latch 18 of the gearbox 2 when it is mounted in the opening 28.
  • Fig. 6 shows the connecting rod linkage extending from the lockbox 1 to the remote gearbox 2.
  • the linkage comprises the first link 11 and a second link 44.
  • the link 11 has a short root portion 46 which enters the lockbox 1 and is driven by the lockbox in a manner known per se .
  • the first link 11 is formed with a crank at 47 and has a longer portion 48 on the opposite side of the crank 47 to the root portion 46.
  • a connection block 50 of cuboidal shape is secured.
  • One end of the link 44 is received in the block 50; as can be seen from Fig.
  • an end portion of the link 44 of substantial length is of generally rectangular cross-section having a pair of opposite, relatively wide, side faces 52 and a pair of opposite, relatively narrow, side faces 54 which are toothed.
  • the interior side faces of the connecting block 50 that are immediately adjacent to the toothed faces 54 are also provided with toothed formations (not visible in Fig. 6 ).
  • the rear side face of the block 50 is fixed to the end of the link 11.
  • the end faces of the block 50 are open to allow passage of the link 11 and the front side face of the block 50 is also open.
  • the formations in the link 44 and the connecting block 50 are able to interengage and, when so interengaged, prevent relative longitudinal movement of the links 11 and 44; the position at which they interengage can, however, be adjusted simply by passing the link 44 out of the connecting block by moving it forwards through the open front side face of the block 50, away from the link 11.
  • the relative longitudinal positions of the links can then be adjusted and the toothed formations interengaged with the links 11 and 44 in different relative longitudinal positions. In this way, the overall length of the linkage between the lockbox 1 and the gearbox 2 can be altered as desired without cropping any members.
  • the connecting rod linkage between the lockbox 1 and the gearbox 3 is substantially the same, having a third link 12 and a fourth link (not clearly visible in Figs. 1 and 2 ), and employs corresponding components. It will not therefore be described again here.
  • the assembly can be installed in an appropriate groove in the edge of a door or window, for example in a Eurogroove. Once so installed the toothed connection is secure because the front side face of the block 50 is closed over by the rear of the faceplate arrangement.
  • connection rod linkages and of the whole assembly, is as in a conventional multipoint lock assembly, but the ability to adjust the lengths of the connecting rod linkages without any special tools makes the installation significantly quicker and easier than if the connecting rod linkages had to be cropped to size.
  • the mushroom roller 60 suitable for use in the multipoint lock assembly described above, but also suitable for use in other multipoint lock assemblies.
  • the mushroom roller generally comprises a locking head 62 and a stem 64 which is formed with an integral peripheral flange 66 partway along its length. A portion of the stem away from the mushroom head is provided with a high friction screw thread 68 which in this particular example is a patch thread.
  • the head 62 of the roller is provided with a slot 70 for engagement by a screwdriver blade.
  • Fig. 8 shows the mushroom roller 60 installed in a multipoint lock assembly which may be of any of a wide variety of designs including the design described above with reference to the drawings but also other multipoint lock assemblies which may in all other respects be entirely conventional.
  • a faceplate 72 and a connecting rod 74 of a multipoint lock assembly The multipoint lock assembly is shown fixed in a frame profile 76, that frame profile typically being the profile of an edge of a door or window.
  • the screw thread 68 of the mushroom roller passes freely through an elongate slot 80 in the faceplate 72 and is in threaded engagement with the connecting rod 74 behind the faceplate 72.
  • the mushroom roller if the mushroom roller is rotated by engaging a screwdriver blade in the slot 70, it can be screwed in or out of the connecting rod 74 moving it towards or away from the faceplate 72.
  • the distal end of the mushroom roller is shown riveted over to form an enlarged distal end 82 which prevents the mushroom roller from being removed from the connecting rod 74.
  • that enlargement is carried out after the assembly of the faceplate 72, the connecting rod 74, and the mushroom roller 60 has been made and prevents the mushroom roller 60 being removed thereafter.
  • mushroom roller which has a head that can readily be moved towards or away from a faceplate arrangement of a multipoint lock assembly without special tools is a valuable feature which can be of assistance during any installation but also during maintenance or retrofitting of a new lock assembly.
  • Figs. 1 to 3 above show tabs 90 connected to the faceplates 4 and 5.
  • Each tab 90 is of approximately oval shape and has two holes 92 and 94.
  • a rivet is passed through the hole 92 and a hole (not visible) in the faceplate 4 or 5 to securely connect the tabs to the faceplate, whilst allowing pivotal movement of the tab about the axis of the rivet.
  • the hole 94 of the tab can then be positioned to one side of the faceplate 4 or 5 and a fastening screw inserted through the hole 94 in the tab to provide additional fastening of the faceplate to the door frame.
  • tabs can be of advantage when first fitting a multipoint lock system, but is of particular advantage when retrofitting part or all of such a system because there may be existing screw holes or other obstructions at other set locations for fastening screws.
