Definitions

  • This invention relates to an espagnolette fastening for a window or door, and which comprises a pinion housing which can be mounted in a closing face of the window or door, an elongate slidable member movable longitudinally between fastening and release positions, a pinion rotatably mounted in said housing and adapted to receive the spindle of an actuating handle which can rotate the pinion between release and fastening positions, and a mechanism interconnecting the pinion and the slidable member and operable to convert rotary motion of the pinion into linear movement of the slidable member.
  • the slidable member often referred to as an espagnolette rod
  • the slidable member is provided with one or more locking elements, which may comprise so-called “mushroom cams", such locking elements being movable between release and fastening positions with respect to corresponding keeper elements, upon linear movement of the espagnolette rod.
  • One widely used type of mechanism for transferring rotary movement of the pinion into linear movement of the slidable member comprises a rack provided on the slidable member and which engages the teeth of the pinion as the later rotates.
  • rack and pinion type of mechanism is not essential to the present invention.
  • espagnolette fastenings have a single espagnolette rod which moves to and fro to move between the release and fastening positions
  • a pair of espagnolette rods which move in relatively opposite directions i.e. towards or away from each other as they move between the release and the fastening positions. Such an arrangement is also within the scope of the present invention.
  • cams In espagnolette type fastenings for doors and windows, and when so-called “mushroom cams” are used as the locking elements, these cams slide into locking engagement with suitably designed keeper elements mounted in the fixed frame in which the door or window is hingedly mounted, and the cams have a cylindrical shank which is received in a slot defined by the respective keeper element, and which resists opening movement of the door or window i.e. in a direction perpendicular to the axis of the shank.
  • each mushroom cam has a flange or dome shaped head at the end of each shank, and which fits within each keeper slot, and resists axial separation between the shank and the keeper. Therefore, the flanged or dome shaped heads provide axial restraint against possible forced separation between the closing face of the door or window and the fixed frame, and in the general plane of the door or window.
  • the purpose of the present invention is to provide an additional locking feature, as a component part of the espagnolette fastening, to provide additional resistance to any attempt at forced relative separation of the fixed frame and the hinged frame in which the door or window is mounted.
  • an espagnolette fastening for fastening an openable window or door member to a fixed frame in which it is mounted, said fastening comprising: a pinion housing which can be mounted in a closing face of said window or door member; a pinion rotatably mounted in said housing and adapted to be rotated by a spindle of an actuating handle between release and fastening positions; an elongate member slidable longitudinally and having a fastening element which is movable with the elongate member between release and fastening positions with respect to a keeper element in the fixed frame; a mechanism arranged within said housing and interconnecting said pinion and said elongate member, said mechanism being operative to convert rotary movement of the pinion into linear movement of said elongate member; and a locking element mounted on said pinion and rotatable therewith, said locking element being movable between a retracted position in which it is accommodated at least partly within said housing when the pinion is in the release
  • the locking element may comprise a claw which can be received at least partly within the housing, when in the retracted position, so that it does not project from the overall device to any appreciable extent, but which can make reliable and robust locking engagement with its keeper when in the locking position.
  • the keeper may comprise a specially designed keeper plate mounted in the fixed frame. Therefore, in a preferred embodiment, by relatively simple means additional security is provided by mounting the claw type locking element on the pinion (in which the pinion may be of standard or well known design), and by providing a suitable keeper plate mounted in the fixed frame.
  • a single slidable espagnolette rod forms said slidable elongate member, and which has a rack engageable by the teeth of the pinion in order to be driven linearly upon rotation of the pinion.
  • more complex designs may be provided, within the scope of this invention, including provision of double espagnolette rods movable in opposite directions, and with any suitable drive mechanism to transfer rotary motion from the pinion into opposite linear movements of the rods.
  • the rod(s) may be provided with mushroom cam(s) or other similar fastening elements.
  • Figure 1 is a side view of the fastening mechanism
  • Figure 2 is a perspective view of the mechanism.
  • an espagnolette fastening according to the invention is designated generally by reference 10, and is adapted to fasten an openable window or door (not shown) to a fixed frame in which it is mounted, the fastening 10 comprising a pinion housing 11 which can be mounted in a suitable recess formed in a closing face of the window or door member.
  • Housing 11 may be of standard design.
  • a pinion 12 is rotatably mounted in housing 11 and is adapted to be rotated by a spindle of an actuating handle (not shown) between release and fastening positions in well known manner.
  • Pinion 12 has peripheral teeth, of which one is shown by reference 13, and which are capable of meshing with a rack (not shown in detail) mounted on an elongate member, in the form of espagnolette rod 14, which is slidable longitudinally between release and fastening positions with respect to a keeper element (not shown) mounted in the fixed frame.
  • the rod 14 has one or more locking cams 15 which may comprise well known "mushroom cams".
  • Rotation of pinion 12 effects longitudinal movement of espagnolette rod 14 so as to move cams 15 between release and fastening positions in accordance with the direction of rotation of pinion 12.
  • a mechanism is arranged within housing 11 and interconnects pinion 12 and rod 14, which is operative to convert rotary movement of the pinion into linear movement of the rod 14, and which, as described above, takes the form of rack and pinion interconnection between pinion 12 and rod 14.
  • other types of mechanism may be provided in order to convert the rotary movement of the pinion into linear movement of the rod 14.
  • a locking element in the form of claw 16 is mounted on pinion 12 and is shown in full lines in a retracted position in which it is accommodated at least partly within housing 11 , and which position it takes-up when the pinion 12 is in the release position.
  • the claw 16 does not project from the housing 11 by any greater extent than the cams 15, and therefore the overall depth of fastening 10, when in the release position, is kept to a minimum.
  • claw 16 can be rotated to a locking position, as shown in dashed outline, when the pinion 12 is rotated by the spindle of the actuating handle to the fastening position, and when claw 16 is in this position it is capable of making locking engagement with a respective keeper in the form of centre keep plate 17 mounted on the fixed frame, in order to resist forced relative separation between the keeper plate 17 and the closing face of the window or door in which fastening 10 is mounted.
  • a slot 16a in claw 16 engages around a strengthened securing bar or rod 17a incorporated in keep plate 17. This resistance to relative separation prevents, or at least resists strongly any forced separation e.g. by use of a jemmy, tending to move the fixed frame and the closing face of the window or door apart in the general plane of the window or door.
  • a single espagnolette rod 14 is provided, but more complex designs may be provided, within the scope of the invention, including provision of double espagnolette rods movable in opposite directions, and with provision of any suitable drive mechanism to transfer the rotary motion of the pinion 12 into opposite linear movement of the rods.
  • the rod or rods are provided with mushroom cams, or other similar fastening elements.
  • the security claw (16) is substantially built—into the housing or gearbox, so that no loose parts are needed for fitting, and can be installed the same as a standard espagnolette fastening;
  • the claw In the closed position, the claw can locate around a security bar provided in the keep plate 17, and protrudes into reinforced part of the fixed frame section;
  • the pinion moves a rack of an espagnolette rod(s) to which the mushroom cams are attached, and these move into standard keeper elements, while at the same time, the claw, which is an integral part of the pinion, moves around and locates in a purpose made keep which is attached to the frame. In the fully closed position, the claw hooks round a bar on the keep preventing the sash and frame being levered apart.
