Definitions

  • the present invention relates to bolt arrangements.
  • Bolt arrangements may be required in many circumstances, for example to secure window handles.
  • Many types of window handle arrangement have previously been proposed, particularly for windows made of metal or plastics extrusions, which may incorporate security mechanisms such as locks, espagnolette mechanisms and the like. It is desirable to be able to disable these handle arrangements by means of a simple mechanism, in the interests of economy, reliability and the like.
  • the present invention provides a bolt arrangement comprising:
  • the bolt member and the link members are integrally moulded. They may be moulded of a resilient material. The resilience preferably tends to urge the bolt member to the advanced position.
  • the hinge connections of the link members may be provided as live hinges.
  • a manual control member is provided to move the actuator member.
  • the manual control member may be a button member.
  • Lock means are preferably associated with the manual control member and releasably operable to disable movement of the control member.
  • the actuator member may be hingedly connected at respective positions to the second link member and to a manual control member.
  • the manual control member may press on the actuator member, when moved, to cause the actuation member to move.
  • the axes of the hinge connections are preferably substantially parallel.
  • the actuator member is preferably constrained, at a position away from the connection with the second link member, to a linear movement.
  • the linear movement is preferably perpendicular to, and offset relative to the hinge axes.
  • the invention also provides a window handle arrangement comprising a base member mountable on a window, a handle member rotatably attached to the base member, and a bolt arrangement according to any of the preceding definitions, the bolt member of the bolt arrangement, when in the advanced position, serving to secure the handle member against rotation.
  • the bolt arrangement is housed within the handle member to engage the base member when in the advanced position.
  • the first link member is hingedly connected with a washer member of the rotatable attachment between the handle member and the base member.
  • Figs. 1 and 2 show a handle arrangement 10, which may be used with a metal or plastics extrusion window.
  • the arrangement 10 includes a handle 12 which is rotatably mounted on a base 14 for turning about an axis 16.
  • the base 14 is, in turn, mounted on the window (not shown).
  • a spindle 18 is mounted at the axis 16 to turn with the handle 12.
  • the spindle 18 extends through the base 14 to engage and operate mechanisms within the window frame, such as espagnolette mechanisms (not shown).
  • a bolt arrangement indicated generally at 20 is provided within the handle 12 and includes a bolt member 22 which has an advanced position (Fig. 1) in which it engages a bolt recess 24 in the base 14 to prevent the handle 12 turning relative to the base 14.
  • the bolt member 22 also has a withdrawn position (Fig. 2) clear of the bolt recess 24, allowing the handle 12 to turn on the base 14.
  • a manual control member in the form of a button, indicated generally at 26, is provided for controlling the bolt member 22.
  • the button 26 may be depressed by the thumb of a hand gripping the handle 12, in order to release the bolt member 22 from the recess 24.
  • the bolt arrangement 20 includes a one-piece moulding of appropriate material (such as a synthetic plastics material) including portions which serve as a washer 28, the bolt member 22, a first link member 30 between the bolt member 22 and the washer 28, a second link member 32 from the bolt member 22 to a hinge 34, and an actuator member 36 from the hinge 34.
  • a second moulding forms the button 26.
  • the tip 37 of the actuator member 36 sits in a concave corner formed in the button 26.
  • a second hinge 39 is provided between the first link 30 and the washer 28.
  • the washer 28 is centred on the axis 16 in the assembled handle 10, as can be seen from Fig. 1, to form a washer within the connection between the handle 10 and the base 14. This provides for smoother movement of the handle 10, and also fixes the position of the washer 28 and the hinge 39.
  • a cavity 40, within the handle 12, accommodates the button 26, the actuator member 36 and the second link 32.
  • the bolt 20 is accommodated either in the recess 24, when advanced, or within the cavity 40, when withdrawn.
  • the button 26 incorporates a lock mechanism 41 generally of the type described in our British patent GB 2375371 and incorporates a short tang 42 which can be turned around a second axis 44 by means of a key operating the lock 41.
  • the tang 42 engages a ledge 46 formed in the wall of the cavity 40 to hold the button 26 in the position of Fig. 1.
  • the lock 41 is operated to turn the tang 42 away from the ledge 46, the button 26 is freed to be pushed into the cavity 40, to the position shown in Fig. 2.
  • the lock 41 is not an essential feature of the invention. There may be applications in which it is not necessary for the button 26 to be lockable.
  • Movement of the button 26 is constrained to a linear movement parallel with the axes 16, 44.
  • the washer 28 is held at a fixed position relative to the handle 12, as has been described and thus, the first link 30 is connected to this fixed position through the hinge 39.
  • the hinge 39 is away from the bolt 22. That is, the first link 30 is attached at one end to the bolt 22, and hingedly connected at its other end to the washer 28.
  • the second link 32 is also attached at one end to the bolt 22. It is important to note that neither link 30, 32 is hingedly connected to the bolt 22. This may be achieved by providing thicker material in the region of the bolt 22 than in the region of the live hinges 34, 39 so that movement takes place preferentially at the hinges.
  • the choice of material for the arrangement 20 may result in some distortion of the moulding in the region of the junctions between the links 30, 32 and the bolt 22, during use, but it is the intention that the angle between the links 30, 32, at the bolt 22, is substantially fixed and that any folding of the arrangement 20 (to be described) will occur at the hinges 34, 39.
  • the hinge 34 is free to move within the cavity 40.
  • the hinge 39 is fixed by the washer 28.
  • the position of the tip 37 is also important and is constrained by the shape of the button 26 to move on a linear path parallel with the axes 16, 44.
  • the button 26 When the button 26 is depressed, by means of a user's thumb, or otherwise, the button 26 moves to the position of Fig. 2. As it does so, the downward force from the button 26 is conveyed to the actuator 36, pressing down on the tip 37. The angled orientation of the actuator 36 results in a force being applied to the link 32, at the hinge 34, in the direction of the vector 48 (Fig. 1). Thus, there is a component of force in the direction of the vector 50. This causes the upper end of the link 32 to be pushed toward the axis 16.
  • the hinge 39 provides the only articulation between the hinge 34 and the washer 28, and accordingly, the direction of the vector 50 will cause the bolt 22 to turn in an anti-clockwise direction (as viewed in Fig. 1) around the hinge 39, thus causing the bolt 22 to move into the cavity 40 from the recess 24, and thus releasing the handle 12 from the base 14 and allowing the handle 12 to turn.
  • the hinges 34, 39 will relax, causing the button 26 to rise and the bolt 22 to return to the recess 24.
  • the lock 41 can be operated to lock the button 26 in that position.
  • the handle 10 consists mainly of four components, namely the handle 12, base 14, button 26 and bolt arrangement 20, the main steps of assembly are to introduce the button 26 and bolt arrangement 20 into the handle 12, and to assemble the base 14 to the handle 12.
  • the button 26 is first introduced into the position of Fig. 1.
  • Introduction of the bolt arrangement 20 into the handle 12 can then be achieved by manipulating the moulding of the arrangement 20 to the position indicated in Fig. 6, in which the actuator 36 has been bent over at the hinge 34 to align the actuator 36 and the second link member 32.
  • This allows the arrangement 20 to be introduced into the cavity 40 from below (as illustrated in Fig. 1), first introducing the actuator 36 and continuing to insert the arrangement 20 until the tip 37 engages the button 26 in the assembled position of Fig. 1.
  • the bolt 22 will have moved through the lower mouth of the cavity 40.
  • the washer 28 is then manipulated to place the washer 28 in the appropriate position around the handle, centred on the axis 16, as illustrated in Figs. 1 and 2.
  • the base 14 can then be assembled to the handle 12, in a manner conventional in itself. This traps the washer 28 in its final position. Other components, such as the spindle 18, are then introduced.
  • the actuator 36 has been described as having a tip 37 which bears on the button 26.
  • the actuator 36 is joined to the button 26 by a further live fringe, so that the tip 37 is permanently fixed to the button 26.
