Definitions

  • the invention relates to locking mechanisms for locking an enclosure to an associated frame.
  • the locking mechanism can be used to lock a door or window leaf into an associated door or window frame.
  • a locking system for locking a closure to an associated frame comprising a bolt and an operating mechanism for mounting on the closure, the bolt including a locking head and the operating mechanism being actuatable to move the bolt from a retracted position in a linear path without rotation for inserting the locking head into a keeper in the frame and then to rotate the bolt to engage the locking head behind the keeper, the operating mechanism being further actuatable to reverse said movements.
  • a door or window comprising a fixed frame and a closure movable into and out of a closed position in which the closure is received in the frame, the closure carrying at least one locking system according to the first aspect of the invention and the frame including at least one keeper, the or each keeper receiving a bolt of an associated locking system.
  • the first housing part indicated at 10 is in the form of a generally elongate rectangular die-cast plate having flanges 11,12 extending along respective longer side edges.
  • One flange 11 is continuous and the other flange 12 is interrupted intermediate its ends by a slot 13.
  • a groove 14 extends along the housing part 10 adjacent the slotted flange 12.
  • the continuous flange 11 has an inner wall 15 that slopes outwardly from a base 16 of the housing to the free end of the flange 11 for a purpose to be described below.
  • the base 16 is provided, intermediate its ends, with a hole 17 which has two arcuate ends 18 interconnected by sides 19 each of which has an arcuate central portion 20 and outwardly directed ends 21.
  • the hole 17 is surrounded by an annular bearing surface 22.
  • Two pegs 23 project from the base 16 on diametrically opposite sides of the hole 17 and are arranged intermediate the flanges 11,12 on the centre line of the housing part 10.
  • Two fixing holes 24 are also provided in the base 16 on the centre line on respective opposite sides of the holes 17 beyond the pegs 23.
  • a crescent-shaped projection 25 is associated with each hole, disposed about said centre line and located on the side of the associated fixing hole 24 remote from the holes 17.
  • Two lugs 26 also project from the base 16 and are located on the centre line of the housing part 10, each lug 26 being adjacent a respective end of the base 16.
  • Each lug 26 is generally oval in shape and is provided with a central hole 27.
  • the groove 14 receives the rack 28 that is shown in Figures 3 and 4.
  • the rack is generally rectangular in cross-section with a toothed surface 29 and an under surface 30 connected by side surfaces 31.
  • the toothed surface 29 has rack teeth 32 in a central portion and a series of longitudinally spaced rectangular cut-outs 33 at each end. The function of these will be described below.
  • the rack 28 fits in the groove 14 with the under surface 30 engaging the flange 12 and with one side surface engaging a base of the groove 14.
  • the toothed surface 29 faces the hole 17.
  • the second housing part 34 comprises a generally rectangular plate-shaped head 35 with a central aperture 36 and a tube 37 extending from the aperture 36 to one side of the head 35.
  • the head 35 fits on to the first housing part 10 with the aperture 35 and the tube 37 aligned with the hole 17 and the head 35 has two holes 38 through which project the pegs 23 on the first housing part 10 to locate the second housing part 34 relative to the first housing part 10.
  • the head 35 is also provided with a locating rib 39 that fits in the slot 13 in the flange 12 to provide further location of the second housing part 34 relative to the first housing part 10.
  • the aperture 36 in the head 35 is provided with a rebate 40.
  • the tube 37 extends from this rebate 40 and is provided with an initial cylindrical portion 41. This is followed by a portion 42 that is inwardly tapered along its length by, for example, two degrees. This is followed by a second cylindrical portion 43 which ends in a second rebate 44. Below the second rebate, the tube 37 is provided with a second tapered portion 45 of lesser diameter than the first mentioned tapered portion 42. This second tapered portion 45 is provided with a pair of diametrically-opposed axially-extending slots 46.
  • the second rebate 44 between the second cylindrical portion 43 and the second tapered portion 45 is not continuous around the tube 37. Rather, it is axially stepped. This is achieved in the following way.
  • Each slot 46 has two side walls, one of which is shown at 47 in Figure 6. At the end of each slot 46 within the tube 37, one side wall 47 extends axially beyond the other side wall 47.
  • the second rebate 44 extends circumferentially from this end of the longer side wall 47 for 90° and then has an axially extending portion towards the end of the tube 37 remote from the head 35 and then has a second 90° circumferentially extending portion which terminates at the inner end of the shorter side wall 47 of the other slot 46.
  • the second rebate 44 is similarly arranged between the inner end of the other longer side wall of the other slot 46 and the inner end of the shorter side wall 47 of the first-mentioned slot 46.
  • the head 35 is provided with oppositely-extending projections 48 each terminating in an arcuate concave recess 49.
  • the second housing part 34 receives a sleeve 50 shown in Figures 7 and 8.
  • the sleeve 50 has a toothed pinion 51 extending around one end and has an internal thread 52 provided within the sleeve 50 at an end of the sleeve 50 opposite the pinion 51.
  • the sleeve 50 fits in the second housing part 34 with the pinion 51 resting in the rebate 40 in the head 35 and with the sleeve 50 extending down the tube 37 and resting on the portions of the second rebate 44 remote from the ends of the slots 46.
  • the sleeve 50 is thus free to rotate relative to the second housing part 34.
  • the sleeve 50 receives the bolt 53 shown in Figure 9.
  • the bolt 53 has a T-shaped locking head 54 at one end and a thread 55 extending along the bolt 53 at an end opposite the head 54.
  • a pin 56 extends radially through the bolt 53 at an end of the bolt 53 opposite the head 54 so that portions of the pin 56 project from diametrically-opposite sides of the bolt 53.
  • the thread 55 is in meshing engagement with the thread 52 in the sleeve and the projecting portions of the pin 56 engage in respective slots 46 in the tube 37.
  • Reverse rotation of the sleeve 50 moves each pin portion back round the associated guideway until it engages a longer side wall 47 of the associated slot 46. Further rotation of the bolt 53 is then not possible and so further rotation of the sleeve 50 causes axial movement of the bolt 53 without rotation with each pin portion entering the associated slot 46 as the bolt 53 moves in a linear path without rotation and retracts into the sleeve 50.
  • each drive rod 57 is in the form of an elongate strip with upwardly and outwardly extending side walls 58.
  • One end of each drive rod 57 is provided with a U-shaped cut-out 59 and an elongate slot 60.
  • each side wall 58 is provided with four longitudinally-spaced rectangular holes 61.
  • the opposite end of the drive rod 57 is provided with an angled tongue 62.
  • Each drive rod 57 is sized to fit on the first housing part 10 to one side or the other of the hole 17 with a lug 26 projecting through the slot 60 of the drive rod 57 and with the U-shaped cut-out 59 embracing a projection 25.
  • One angled side wall 58 of the drive rod 57 engages and slides along the inner wall 15 of the uninterrupted flange 11 of the first housing part 10.
  • the end of the drive rod 57 overlaps the associated end of the rack of the 28 with one or more of the pairs of holes 61 being engaged with one or more of the teeth formed by the cut-outs 33 on the rack 28, depending on the degree of overlap. Plainly, the overlap can be adjusted as required.
  • Each guide member 63 is in the form of a plate provided at one end with a hole 64 and at an opposite end with a U-shaped cut-out 65 to provide a pair of projecting fingers 66 each terminating in a stepped portion 67.
  • Each guide member 63 fits on to the first housing part 10 to one side of the hole 17 and is screwed to the first housing part 10 by a screw extending between the hole 64 and the hole 27 in the associated lug 26.
  • the lug 26 acts to space the guide member 63 from the base 16 and so allows sliding movement of the associated drive rod 57 and the rack 28.
  • the fingers 66 embrace the associated projection 25 and the stepped end portions 67 engage with the head 35 of the second housing part 34.
  • a window comprises a fixed frame which receives a leaf connected to a window by hinges or friction stays, for example, so that the leaf can be closed into and opened out of the frame.
  • the leaf is formed by members which hold the glass and also mount the connections. These members are generally rectangular in cross-section with side surfaces parallel to the plane of the glass, interconnected by inner and outer surfaces. The inner surface mounts the glass and the outer surface is, when the leaf is closed into the associated frame, parallel to but spaced from an associated frame surface. The spacing is normally designed to be about 6mm.
  • the locking system assembled as described above with reference to the drawings is designed to be mounted on the outer surface of a member forming the leaf.
  • a member forming the leaf In some such members, particularly when formed of plastics material, there is provided a channel in this surface and the housing can then be dimensioned to fit into the channel. In this case, it will be necessary only to drill a hole in the base of the channel to accommodate the end of the tube 37 and then screw the first housing part 10 to the member by screws extending through the fixing holes 24.
  • drive rods 57 When mounted on a leaf member, drive rods 57 will project from respective opposite ends of the housing.
  • One tongue 62 of one drive rod 57 is connected to a handle-operated drive mechanism by a drive transfer member (not shown).
  • the handle-operated mechanism may be an espagnolette-type mechanism or any other mechanism that converts rotation of a handle into reciprocating movement of the drive transfer member. It will be appreciated that the handle need not be mounted on the same leaf member as the locking system; it could be mounted on another member with the drive transfer member flexing round the corner or corners between the handle and the locking system.
  • the frame surface opposite the locking system is provided with a keeper (not shown) including a hole of a shape similar to and in register with the hole 17 formed in a plate (not shown) of the keeper, with the keeper being cut away behind the plate to allow the head 54 to engage behind the plate.
  • the drive rod 57, the rack 28 and the handle and the drive transfer member are so arranged that as the handle (not shown) is operated to latch a leaf to the frame, the drive transfer member causes movement of the associated drive rod 57 relative to the housing part 10 such that the rack 28 rotates the pinion 51 on the sleeve 50.
  • the rotation is arrange to be such that it causes movement of the bolt 53 in a linear path without rotation, as described above, out of the tube 37 so that the head 54 enters the hole in the keeper in the frame.
  • This movement of the bolt 53 continues until the pin projections 56 leave the associated slots 46 and enter the guidways. Again, as described above, the bolt 53 is then constrained to rotate with the sleeve 50 through the 90° of the guideways.
  • the mechanism shown achieves movement of the bolt in a linear path without rotation followed by rotation of the head at the end of such movement using a rotating sleeve and a thread
  • any mechanism could be used that achieves this combination of movement.
  • the direction of movement of the drive rod 57 and the rack 28 is at right angles to the direction of movement of the bolt 53, this need not necessarily be the case.
  • the bolt 53 could move in a direction parallel to the direction of movement of the drive rod with a different operating mechanism being provided between the drive rod 57 and the bolt 53 - for example, the drive rod could drive the bolt 53 through a portion of the pin 56 projecting through the tube 37.
