Definitions

  • Espagnolette bolt mechanisms are used in doors and windows to achieve a secure fastening of the door or window and generally include a drive mechanism which transmits rotation of a handle into translational movement of an espagnolette bolt.
  • the espagnolette bolt generally includes locking pins which engage the side of the frame adjacent the mechanism. The locking pins are usually received in a striking plate or plates attached to the fixed frame of the assembly.
  • Espagnolette bolt mechanisms typically provide one drive transfer member carrying the locking pins, extending on one or both sides of the drive mechanism, and which moves between a locked and an unlocked position.
  • the drive transfer member or members are usually located in shallow grooves in the movable leaf of the window or door.
  • a window or door fitted with an espagnolette bolt mechanism may be susceptible to forced opening. All of the locking pins in espagnolette bolt mechanisms engage in their respective striker plates from the same direction, therefore, a force applied to the window or door in an opposing direction may generate sufficient movement to disengage the locking pins and permit opening of the window or door.
  • the mechanism further comprises striker plates for connection to the fixed frame and arranged to receive and retain the locking pins in the locked position.
  • the striker plates typically have pairs of opposite hand locking pin receiving openings.
  • each striker plate receives a pair of locking pins.
  • both of each pair of locking pin receiving openings may be engaged simultaneously when, in use, the locking pins are moved towards one another.
  • striker plates having more than one pair of locking pin receiving openings are fitted, a first pair of locking pin receiving openings may be used when the movable leaf is in a fully locked position in the fixed frame.
  • a second pair of locking pin receiving openings may be used to lock the movable leaf in a position slightly ajar to allow, for example, night ventilation.
  • a rubber seal is usually provided between the periphery of the movable leaf and the frame to provide greater sound proofing and weather protection.
  • the rubber seal becomes compressed between the fixed frame and the movable leaf as the window or door is closed.
  • the degree of seal compression may be altered by adjusting the spatial relationship between the primary drive transfer member and faces of the locking pin which contact the striker plate. This may be achieved by the use of adjustable eccentric locking pins connected to the primary drive transfer members.
  • Locking pins connected to the secondary drive transfer members may be fixed and of a smaller gauge relative to the locking pins connected to the primary drive transfer members. Locking pins connected to the secondary drive transfer members should be substantially unloaded under normal operation of the mechanism. However, if the movable leaf is forced either in a direction substantially parallel but opposite to the locking direction of movement of the secondary drive transfer members or transversely out of the frame, the locking pins connected to the secondary drive transfer members engage the striker plates located on both sides of the drive transfer mechanism and resist movement of the movable leaf relative to the fixed frame.
  • the drive transfer mechanism comprises a drive pinion mounted on a housing for rotation relative to the housing by the handle, the pinion meshing with the primary drive transfer member.
  • the primary drive transfer members preferably overlay the secondary drive transfer members, the primary drive transfer members lying closest to the drive transfer mechanism.
  • the driving elements may be connected to the drive transfer members via protrusions extending from the driving elements engaging with cut away portions of the drive transfer members. A protrusion extending from one of the driving elements connecting said driving element with the primary drive transfer members is longer than the protrusion extending from the other driving element connecting it with the secondary drive transfer members.
  • end portions of the drive transfer members project beyond guide members which are fixed at corners of the movable leaf, for engagement with shoot bolt keeps on opposite ends or sides of the fixed frame when the mechanism is in the locked position, and where the end portions of the drive transfer members are retracted into the guide members when the mechanism is in the unlocked position.
  • the drive transfer mechanism comprises a small gear wheel arranged between the driving elements and being in meshing engagement with the driving elements so that movement of said one driving element through the drive causes simultaneous translatory movement in the opposing substantially parallel direction of the other driving element, where the gear wheel is rotatable about an axis normal to a plane containing the directions of movement of the driving elements.
  • the small gear wheel is made of steel.
  • a mechanism which includes a drive transfer mechanism 3 for connection to a rotatable handle which fits into a square hole 5.
  • the drive transfer mechanism 3 is adapted, in use, to convert rotary movement of the handle into simultaneous translatory movement of driving elements 6 in each of two opposing substantially parallel directions.
  • Primary drive transfer members 1 and secondary drive transfer members 2 extend on both sides of the drive transfer mechanism 3.
  • the drive transfer members 1 and 2 are connected to the driving elements 6.
  • the drive transfer members 1 and 2 move in a groove at the end face of a window or door.
  • Locking pins 4 are connected to both the primary and secondary drive transfer members 1 and 2.
  • the locking pins 4 are arranged in pairs on both sides of the drive transfer mechanism 3 with one of each pair connected to the primary drive transfer members 1 and the other of each pair connected to the secondary drive transfer members 2. In use, rotation of the handle causes movement of the primary and secondary drive transfer members 1 and 2 in opposing substantially parallel directions and cause each pair of locking pins 4 to move towards and away from one another.
  • the pairs of locking pins 4 are positioned to move into and out of engagement with striker plates 20 (shown in Figure 5) connected to the fixed frame. Each pair of locking pins 4 engages and disengages with a pair of locking pin receiving openings, one of each pair of locking pin receiving openings located on each of two opposite faces of the striker plate 20, when, in use, each pair of locking pins 4 move towards or away from one another.
  • the locking pins 4 connected to the primary drive transfer members 1 are eccentrically adjustable to allow adjustment of the location of a centre of the locking pins 4 relative to the primary drive transfer members 1 in order to permit adjustment of the seal compression of the movable leaf in the fixed frame when in the locked position.
  • the locking pins 4 connected to the secondary drive transfer members 2 are fixed and of a smaller gauge compared to the locking pins 4 connected to the primary drive transfer members 1.
  • the primary drive transfer members 1 overlay the secondary drive transfer members 2 such that the primary drive transfer members 1 lie nearest the drive transfer mechanism 3 and the secondary drive transfer members 2 lie furthest from the drive transfer mechanism 3. Cut away portions in the secondary drive transfer members 2 allow locking pins 4 connected to the primary drive transfer members to protrude through the secondary drive transfer members 2.
  • the driving elements 6 are connected to the drive transfer members 1 and 2 via protrusions 8 and 9 engaging with cut away portions 10 and 11.
  • the adjustable eccentric locking pins 4 connected to the primary drive transfer members 1 ensure that the bulk of the force transferred from the drive transfer mechanism 3 to the drive transfer members 1 and 2 is carried by the primary drive transfer members 1.
  • a pinion 7, having the hole 5 therein, is mounted on a housing 16 of the drive transfer mechanism 3.
  • the pinion 7 has three teeth for engagement with cut-away portions formed integrally in the primary drive transfer members 1. Rotation of the handle causes the pinion 7 to rotate and corresponding translatory movement of the primary drive transfer members 1.
  • FIG. 2 shows in detail the drive transfer mechanism 3.
  • Both of the driving elements 6 have toothed racks 18 facing inwardly for meshing engagement with a gear wheel 17 rotatable about an axis normal to a plane containing the directions of movement of the driving elements 6.
  • the gear wheel 17 may be made from steel or other suitable material.
  • the driving elements 6 rest adjacent the secondary drive transfer members 2. Translatory movement of the driving element 6 connected to the primary drive transfer members 1 causes translatory movement of the other driving element 6 in a substantially parallel opposite direction.
  • the driving elements 6 and small gear wheel 17 are positioned on a support member for fixing to the window or door.
  • the secondary and primary drive transfer members 2, 1 are then located on the protrusions 8, 9 of the driving elements 6.
  • the drive transfer mechanism 3 having the drive pinion 7 is connected to the primary drive transfer member 1, and the locking pins 4 fixed to the drive transfer members 1, 2.
  • a further feature of the present invention may be to extend the drive transfer members 1 and 2 beyond guide members which are fixed at corners of the movable leaf, for engagement with shoot bolt keeps on opposite ends or sides of the fixed frame when the mechanism is in the locked position, and where the end portions of the drive transfer members 1 and 2 are retracted into the guide members when the mechanism is in the locked position.
