Definitions

  • This invention relates to a closure device for use with an openable door or window, referred to hereinafter as a movable closure member, and which is intended to be mounted on a closing face of the movable member and to cooperate with a fixed keeper mounted on a cooperating face of a fixed frame in which the closure member is slidably mounted for movement between open and closed position in the plane of the movable member.
  • an espagnolette fitting usually comprises a "gearbox" which is mounted in a recess in the closing face of the closure member, and which has a square drive socket which receives a spindle of an operating handle which is rotated in order to actuate the fitting between a release position and a locking position.
  • Rotation of the internal components of the gearbox is translated into linear movement of one or more slide bar or rod (usually referred to as an espagnolette rod) carrying locking or “mushroom” cams which are movable into and out of engagement with respective keeper elements of a keeper arrangement on the fixed frame.
  • slide bar or rod usually referred to as an espagnolette rod
  • locking or “mushroom” cams which are movable into and out of engagement with respective keeper elements of a keeper arrangement on the fixed frame.
  • a mushroom cam is, effectively, a cylinder with a circular flange at one end, and the circular flange fits over the keep, and with the cylindrical part sliding through a slot defined in the keep. Therefore, in practice, it is only the diametrically opposed small rim portions which provide resistance against relative separation. The rest of the circular flange is redundant, in that it does not have any retaining function. However, it is presently necessary to provide a complete circular flange, because of the means of adjustment usually provided in a standard mushroom cam.
  • each mushroom cam usually has in its head portion a hexagonal socket into which an Allen key or the like can be entered, and which allows the cam to be rotated and via an eccentric arrangement, this increases or reduces the amount of transverse "pull" during locking. This is required in order to compensate for any sealing deficiencies in the installation i.e. to take up any excessive clearance between closing frame components and wiper and other seals carried thereby.
  • the present invention seeks to provide a simplified espagnolette fitting, and/or a simplified keeper arrangement for use therewith.
  • the invention therefore does not utilise existing mushroom cams, but instead employs, in one preferred embodiment, a series of "tangs", spaced apart along its length.
  • a generally similar design of keep may be provided, and which is preferably of one-piece formation, and having matching tang or holding portions, but also provided with slots between the holding portions on the keep to allow registry, followed by linear movement.
  • a closure device which is adapted to be mounted on a closing face of a door which is slidable, in a direction parallel to the plane of the door, between open and closed positions with respect to a fixed rectangular frame in which the door is slidably mounted (and having a keeper with a locking formation provided on a fixed vertical frame member which co-operates with the closure device on the closing face), and in which the closure device comprises:
  • the closure device of the invention therefore is similar to existing espagnolette fittings, in that it locks and seals in the same plane, but has many locking/sealing points along its length. Sealing adjustment, unlike existing arrangements of eccentric cams on espagnolettes fitting into fixed keeps, is catered for by using slots which traverse the keep (preferably a continuous one-piece keep) to generate a required correct sealing gap.
  • the closure device of the invention therefore is designed to provide a more secure product than existing espagnolette fittings, whilst maintaining the same ease of assembly, which is of particular advantage of espagnolette fittings, compared to the more labour intensive route required by the use of another well known closure device in the art, known as "shootbolts" .
  • shootbolts another well known closure device in the art.
  • the construction and arrangements of shootbolts will be well known to those of ordinary skill in the art, and need not be described any further herein.
  • closure device for use with a hingedly mounted closure member shown in Figures 1 to 9, and in which:
  • closure device will first be described with reference to Figures 1 to 9 (to form a background to description of the preferred embodiments of the invention illustrated in Figures 10 to 13, and 10a to 13a), and which are intended to be used with a hingedly mounted closure member.
  • Figure 5 is a transverse cross-section view of the frame components
  • reference 10 identifies an extruded PVCU section which forms one of the frame members of a fixed rectangular frame, and which carries a keeper arrangement having three integrally connected components identified by reference 11.
  • Reference 12 identifies an extruded PVCU section forming one frame member of a rectangular frame of the door or window, and component 12 defines a mounting recess 13 in which is mounted an embodiment of closure device according to the invention, designated generally by reference 14, and which cooperates with the keeper arrangement 11.
  • the closure device 14 includes linearly displaceable locking tangs, which move into and out of locking engagement with corresponding components of the keeper arrangement, upon operation of a handle (not shown) which applies rotary actuation, or de-actuation movement to the locking components.
  • Figures 1 and 2 are perspective and exploded views from opposite sides of the closure device 14, and the keeper arrangement 11.
  • the closure device 14 has an actuator device in the form of a gearbox 15 which can be operated to apply linear movement to locking tangs 16 which are slidably movable into and out of engagement with locking formations 17 of the keeper arrangement 11, which, as shown in Figures 1 and 2, is a one-piece keeper formation.
  • the tangs 16 are carried by a slide bar or rod 16a (forming an elongate actuator element) which is linearly displaceable upon actuation of the gearbox 15.
  • the rod 16a is of one-piece formation.
  • the rod 16a could be replaced by a 2-part slide rod arrangement, in which the rods are movable in opposite directions during locking and unlocking operations.
  • a suitable motion-reversal mechanism will then be provided in the gearbox 15, to apply opposite movements to the slide rods.
  • each tang 16, 17 is L-shaped in cross-section, and preferably is integral with (one piece) the element which carries it.
  • Figures 3 and 4 are plan views showing cooperation between the closure device and the keeper arrangement, and showing adjustment into and out of locking engagement.
  • the references 14 are applied to the cooperating parts of the closure device, and the references 17 are applied to the component parts of the keeper arrangement.
  • the "tangs" 16 comprise locking elements which are connected to the elongate actuator element 16a and which are movable into and out of engagement with locking formations 17 on the keeper upon movement of the elongate actuator element to and from its operative position.
  • the tangs 16 comprise elements which are L-shaped in cross section, to engage with the respective locking formations, and to resist forced separation of the closure device and the keeper in a direction generally perpendicular to the closing face, when the closure member (openable door or window) has been moved to its closed position.
  • the tangs 16 are of one piece formation with the elongate actuator element 16a, evidently there are other means whereby the locking element(s) (16) can be connected to the elongate actuator element.
  • interengaging elements 16 and 17 may include interengaging T-shaped formations.
  • FIG. 10 to 13 of the drawings a first preferred embodiment of the invention will be described, and which is designated generally by reference 200.
  • the closure device shown in Figures 10 to 13 is adapted for use with a patio door, in which the door moves in its own plane to and from a closed position with respect to the fixed rectangular frame in which it is slidably mounted.
  • the closure device incorporates an elongate actuator element (equivalent to element 16a described above) which is linearly displaceable in a direction generally lengthwise of the closing face, the actuator element being displaceable between an operative position and an inoperative position by operation of an actuator device.
  • At least one locking element (equivalent to locking element 16) which is connected to the elongate actuator element and which is movable into and out of engagement with a locking formation on the keeper (on the fixed upright face of the fixed rectangular frame) upon movement of the elongate actuator element to and from its operative position.
  • the locking element has an inturned flange portion which is engageable with the locking formation so as to resist forced separation of the closure device and the keeper in a direction generally perpendicular to the closing face.
  • FIG. 10 to 13 The embodiment shown in Figures 10 to 13 is generally similar to the examples described above, except that the patio door moves in its own plane, between open and closed positions. It follows therefore that the movement of the closure device (mounted on the closing face of the patio door) relative to the keeper (on the fixed vertical frame member of the fixed rectangular frame), is different from the movement of the closure device of a hinged window. However, upon movement of the patio door to the closed position adjacent to the fixed vertical frame member, operation of the actuator device then causes relative vertical movement between the locking element(s) and the corresponding portions of the locking formation on the keeper.
  • FIG. 10 to 13 there is shown a lengthy assembly, which will extend throughout the height of the closing face of the patio door, and also the matching locking formations on the keeper on the vertical frame member of the fixed frame.
  • the assembly includes a first housing 201 in which a key operated locking cylinder barrel (not shown) can be mounted, which can be operated in order to lock the closing face of the patio door in the closed position.
  • a second housing 202 which receives a square cross section bar of an operating handle (not shown), which operates a slidable locking mechanism (designated generally by reference numeral 204) between locked and release positions.
  • the housings 201, 202 project laterally from one side of a mounting strap 203 which is intended to be mounted on the closing face of the patio door.
  • the mounting strap extends throughout at least the major part of the height of the door and also slidably mounts the linearly displaceable components of the locking mechanism.
  • Figures 10 to 13 utilises many of the locking components described in more detail with reference to Figures 1 to 9.
  • the preferred embodiment of the invention of Figures 10 to 13 is applied specifically to the closing face of a slidable patio door.
  • the embodiment of the invention shown in Figures 10 to 13 is one example of a closure device which is adapted to be mounted on a closing face of a patio door which is slidable, in a direction parallel to the plane of the door, between open and closed positions with respect to a fixed rectangular frame in which the door is slidably mounted (and having a keeper with a locking formation provided on a fixed vertical frame member which co-operates with the closure device), and in which the closure device comprises:
  • FIG. 10a to 13a A modified, but generally similar embodiment of the invention is shown in Figures 10a to 13a.
  • the operating handle (not shown) will be mounted rotatably in socket 205 of one-piece housing 206, and a key operated locking cylinder barrel will be mounted in socket 207.
  • the handle is used to move the door between open and closed positions, and the internal arrangement of the mechanism within the housing 206 is such that the handle is held rigid in a horizontal position at all times, except when the door has been moved to its fully closed position.
  • the door When the door is moved to the fully closed position, it abuts a vertical end frame member of the fixed frame in which the door is slidably mounted, and thereby triggers a spring-loaded disabling mechanism within the housing which releases the handle and allows it to be pivoted upwardly (to lock the door in the closed position by linear movement of the locking tangs into engagement with the locking formations on the keeper). The cylinder lock will then be operated to prevent downward unlocking movement of the handle.
  • the cylinder lock When it is desired to unlock and open the door, the cylinder lock is unlocked and which allows the handle to be pivoted downwardly to disengage the locking tangs and the locking formations, and the door can then be slid open by pulling or pushing on the handle. As the door moves away from the end frame member, the disabling mechanism is activated so that the handle is held solid in the horizontal position to facilitate manual opening/closing of the door.
  • a spring-loaded plunger 208 projects from the closing face of the door, and disables or activates the disabling mechanism respectively as the door approaches or moves away from the end frame member.
