Preferably, the handle axis is generally parallel to the body axis when the handle is at rest. Brief Description of the Drawings 20 A preferred form of the present invention will now be described by way of example with reference to the accompanying drawings wherein: Figure 1 is a schematic isometric view of the internal mechanism of a lock for a sliding door or window; Figure 2 is a schematic isometric view of the lock of Figure 1; 25 Figure 3 is a schematic parts exploded isometric view of the lock of Figure 1; Figure 4 is a schematic isometric view of a handle assembly to be used with the lock of Figure 1; Figure 5 is a further schematic isometric view of the handle assembly of Figure 4; 5 Figure 6 is a schematic parts exploded isometric view of the handle assembly of Figure 4; and Figure 7 is a schematic isometric view of a keeper employed with the lock of Figure 1. 5 Detailed Description of the Preferred Embodiments In the accompanying drawings there is schematically depicted a lock 10 for a sliding door. The lock 10 includes an outer hollow body 11 consisting of two housing portions 12 and 13 within which the operating mechanism of the lock 10 is generally located. 10 The lock 10 is intended to be mounted in the vertical frame member 14 of a sliding door or window. Preferably the frame member 14 would be a hollow extruded aluminium section. The lock 10 further includes handle assemblies 15, each assembly 15 being mounted on a respective one of the sides of the sliding door or window. Only one of the is assemblies is illustrated in Figures 4 and 5. Each handle assembly 15 includes a mounting plate 16 upon which there is pivotally mounted a handle 17. In that regard the handle 17 is elongated and has a longitudinal axis 18 that is generally parallel and transversely spaced from the longitudinal axis 19 of the body I 1 when the handle 17 is at rest. Each mounting plate 16 20 is also elongated so as to have a longitudinal axis 20. The axes 18, 19 and 20 are generally parallel with the axis 18 displaced laterally from the axes 19 and 20, that is displaced laterally from the edge face 21 of the body 11, the edge face 21 being provided by the housing portions 12, when the handle 17 is at rest. The handle 17 is elongated and is configured and positioned so that it may be 25 held with the palm of the hand so that a user may grip the handle 17 with their fingers and move the handle 17 angularly in the direction of the arrow 22. The handle 17 is moved angularly through an actuate angle of approximately 200 from the first position (rest position) shown in Figure 4 to the second position as shown in Figure 5, that is the handle 17 is moved away from the lock cylinder 49. In moving from the position shown in 6 Figure 4 to the position shown in Figure 5, the handle 17 moves away from the edge face 21 of the lock 10 and therefore the edge 23 of the frame member 14. The handle 17 pivots about an axis 24 that is normal to the axes 18, 19 and 20. The axis 24 is provided by hub assemblies 25, each assembly being operatively associated s with a respective one of the handles 17. Each handle 17 is displaced from the axis 24 by a radius supplied by the handle mounting 109, but pivots in the direction 22 about the axis 24. Each handle 17 includes a generally cylindrical projection 26 that is slidably located within a generally cylindrical aperture 27 so that each handle 17 is supported for 10 angular movement about the axis 24. Each projection 26 has an aperture 28. Engaged with each projection 26 is a cam member 29 having a projection 30 that is received within the adjacent aperture 28. Each projection 26 further has a projection 31 that is centrally located and received within a circular aperture 32 of the associated cam member 29. A washer 33 engages each projection 31, with a threaded fastener 34 passing through and 15 engaging each washer 33 to engage threadably within the associated projection 31. Each cam member 29 has a square aperture 35 that receives a boss 36, each boss 36 also having a square passage 37. Operatively associated with each cam member 29 is a locating/biasing block 38 that is slidably received within the associated mounting plate 16 so as to be guided by 20 guide flanges 39 for linear movement generally perpendicular to the axis 24 and therefore generally parallel to the axis 20. Each block 38 is urged by means of springs 40 to engage the cam surface 41 of the associated cam member 29. Each cam surface 41 includes a ridge 42 that engages a corresponding recess 43 in the associated block 38 to act as a locating mechanism for the cam member 29. Pivoting of the cam member 29 also causes 25 sliding movement of the associated block 38 to further compress the springs 40 so that the block 38 urges the associated cam member 29 to the position as shown in Figure 4. That is a position at which the handle 17 is oriented with its axis 18 parallel to the axis 20 (rest position). Each cam member 29 has an arm 43 that engages "stops" 44 to limit angular 30 movement of the associated handle 17. The stops 44 are located so that each arm 41 can 7 move approximately 200 (from the position shown in Figure 4) both clockwise and anti clockwise. Accordingly each arm 43 can move angularly through a total angular displacement of about 400 about the axis 24. Each handle 17 receives an "infill" 45. 5 The mounting plates 16 are coupled by means of threaded fasteners 46 that pass through the door and plates 16, with the head of each fastener 46 engaging one plate 16 and the threaded shafts of the fasteners 46 engaging within a threaded projections 47 of the other plate 16. Each plate 16 has an aperture 48 through which their projects the lock cylinder io 49, the cylinder 49 having a longitudinal axis 106 that is parallel to the axis 24 but spaced therefrom. The cylinder 49 is spaced from the handle 17. Operatively associated with each plate 16 is a cover 50 that is slidable between a position covering the end face of the cylinder 49 or exposing the end face of the cylinder 49 for access by a key. Each cover 50 has locating projections 51 that locates the cover 50 in a selected one of the two is positions with respect to the cylinder 49. The handle mounting 109 displaces the handle 17 laterally relative to the cylinder 49. Slidably mounted within the body 11 is a slave tongue (slide) 52. The slave tongue 52 is slidably guided by means of sliding engagement with the side walls 53 and 20 54 so as to be movable along a linear path generally perpendicular to the axis 24 and parallel to the axes 18 and 20. The tongue 52 has fixed to it a pin 55 (keeper engaging member). The pin 55 is fixed to the tongue 52 by being located in the aperture 56. The pin 55 is provided to engage a keeper 57 having an eyelet 58 into which the pin 55 can be selectively located to retain the door in the closed position. The keeper 57 is fixed to the 25 surrounding door frame. The tongue 52 has a passage 59 that receives a rod 60. The rod 60 being fixed to the tongue 52 by means of a threaded fastener 61 threadably engaged in a passage 62 intersecting with the passage 59.

8 The rod 60 is fixed to a lock member in the form of first slide bar 62 by means of a threaded fastener 63 threadably engaged with a passage 64. The passage 64 intersects with a further passage 65 through which the rod 60 passes. The bar 62 therefore moves in unison with the tongue 52. s The bar 62 has captively located with respect to it a catch assembly including a pin 66. The pin 66 is slidably located within a recess 67 of the bar 62. Also located in the recess 67 is a spring 68 that urges the pin 66 outwardly with respect to the bar 62. Retaining the pin 66 in the recess 67 is a plate 69 fixed to the housing 11, and having an aperture 70 through which the nose 71 of the pin 66 projects. A shoulder 72 of 1o the pin 66 abuts the plate 69 so that the pin 66 is retained in the recess 67 when the pin 66 is aligned with the aperture 70. The plate 69 is located to project into the slot 73 of the body 11. The keeper 57 has a generally cylindrical projection 74 that engages the nose 71 when the door is closed, to push the pin 71 into the bar 62 to enable sliding movement of 15 the bar 62 in the direction of the longitudinal axis 20. The pin 66 only projects through the aperture 70 when the door is opened, that is in the lock 10 is moved away from the keeper 57 sufficient to allow the spring 68 to move the pin 66 to a position projecting from the edge surface 21 as shown in Figure 1. The bar 62 slidably engages the internal surface of the wall 53 so as to be guided 20 thereby. The bar 62 also slidably abuts a further slide bar 75. The bar 75 not only slidably engages the bar 62 but also slidably engages the wall 54 so as to be guided thereby. Extending between the bar 62 and flange 105 is a spring 76 that urges the bar 62 to move in the direction of the arrow 77. The direction 77 is parallel to the axis 20. Although the rod 60 is fixed to the bar 62, the rod 60 is movable relative to the 25 bar 75. The bar 75 has a longitudinal slot 78 through which there passes a threaded fastener 79 that engages the cylinder 49 to aid in retaining the cylinder 49 in position fixed in the body 11. The slot 78 in the bar 75 enables relative movement of the bar 75 with respect to the threaded fastener 79.

9 Mounted on the bar 75 is a pawl 80. The pawl 80 is pivotal about a pivot pin I10 so as to be pivotable about an axis 81. The axis 81 is generally perpendicular to the rod 60 and therefore perpendicular to the axes 18 and 20 while parallel to the axis 24. The pawl 80 has a projection 82 that is slidably located in an "L" shaped slot 83 in the 5 housing 11. The slot 83 has a longitudinal portion 84 and a transverse portion 85. The longitudinal portion 84 is parallel to the axis 20 while the transverse portion 85 is generally normal to the portion 84. A spring 86 extends between the bar 75 and pawl 80 to urge the pawl 80 so that the projection 82 will move from the longitudinal portion 84 into the transverse portion 85 when aligned therewith. When the projection 82 is in the 10 transverse portion 85, the bar 75 is prevented from longitudinal movement, that is movement in the direction of the axis 20. When the projection 82 is located in the longitudinal portion 84 the bar 75 can move longitudinally, that is parallel to the axis 20. Pivotally supported by the housing II is a hub 87 with cylindrical portions 88 slidably supported in cylindrical openings 108 of the housing 11. The hub 87 has is apertures 89 that receive the bosses 36 so that angular movement of the bosses 36 about the axis 24 causes a corresponding angular movement of the hub 87, also about the axis 24. Accordingly pivoting movement of the handle 17 in the direction of the arrow 22 causes a corresponding angular movement of hub 87 about the axis 24. The hub 87 has an arm 90 that engages a lever 91 to cause pivoting movement 20 thereof about an axis 92. The axis 92 is parallel to the axis 24 but transversely spaced therefrom, and therefore is generally normal to the axes 18 and 20. The lever 91 abuts an extremity of the bar 62 so that angular movement of the lever 91 in the direction of the arrow 93 causes linear movement of the bar 62 in a direction opposite the direction 77. In respect of the keeper 57, it should be appreciated the keeper 57 includes a base 25 94 to which there is adjustably attached a keeper member 95 having the eyelet 58 and projection 74. By operation of threaded fastener 96, the position of the eyelet 58 and projection 74 can be adjusted relative to the base 94 that is fixed to the door frame surrounding the sliding door. The abovementioned lock 10 has snib 97 that is slidably mounted for movement 30 in a direction parallel to the axis 20. The snib 97 projects through the opening 107.

10 Projecting inwardly of the lock from the snib 97 is a blade 98 that slidably passes through a slot 99 of a support plate 100 and through the slot 106 in the housing 11. The support plate 100 is held in position by being "sandwiched" between the cover 16 and the door or body 11 of the lock 10. The blade 98 projects into the body 11 through the slot 106 so as 5 to engage a slot 101 of the bar 75 so that movement of the snib 97 in the direction of the axis 20 will cause a corresponding movement of the bar 75. The bar 75 when moved in the direction of the arrow 77 is located between a projection 102 of the hub 87 and the wall 54 so as to prevent movement of the handle 17 since the hub 87 is prevented from pivoting. The pawl 80 is prevented from entering the slot portion 85 by means of the cam i member 103 of the lock cylinder 49. Accordingly the bar 75 can again be moved by the snib 97 to allow operation of the handle 17. In operation of the above described lock, assuming it is unlocked, that is the key 104 has been operated to move the cam member 103 to the position shown in Figure 1, that is a position retaining the pawl 80 in the slot portion 84, then to open the door a user is grips the handle 17 by placing their palm against the handle 17 and enclosing the handle 17 with their fingers and moving the handle 17 in the direction of the arrow 22 so that the handle 17 moves from the position shown in Figured 4 to the position shown in Figure 5. This movement causes angular movement of the hub 87 that in turn causes angular movement of the lever 91 to move the bar 62 in a direction opposite the arrow 77 so as to 20 move the pin 55 from within the eyelet 58. Continued pressure applied to the handle 17 in the same direction that was used to pivot the handle 17 to the position shown in Figure 5 will then cause the door to open. As the lock 10 moves away from the keeper 57, the projection 74 allows the pin 66 to project through the aperture 70 as the pin 66 is now aligned therewith. When the handle 17 is released it will return to the position shown in 25 Figure 4 under the influence of the springs 40 pushing on the blocks 38. However the bar 62 is maintained stationary by means of the pin 66 engaging with the plate 69. Accordingly the pin 55 is retained in the lowered retracted position, that is the position at which is was removed from and was clear of the eyelet 58.

11 When the door is to be closed, the lock 10 is moved toward the keeper 57. Ultimately the projection 74 engages the pin 66 and retracts the pin 66 into the bar 62. Under the influence of the spring 76, the bar 62 is moved in the direction of the arrow 77 and the pin 55 located in the eyelet 58. 5 The door can be locked from the inside by operation of the snib 97. By moving the snib 97 in the direction of the arrow 77, the bar 75 is moved so that it is positioned between the projection 102 and wall 54. The handles 17 are then prevented from moving to retract the pin 55 from within the eyelet 58. When the door is again to be opened, the snib 97 is moved in the reverse direction thereby freeing the projection 102 for movement )o and therefore the handles 17. By operation of the key 104, the lock 10 can be arranged in a "locked" configuration maintaining the door closed. The key 104 is manipulated to operate the cylinder 49 (from either side of the door) to move the cam member 103 in the direction of the arrow 105 about the longitudinal axis 106 of the cylinder 49. This movement of the 15 cam member 103 releases the pawl 80 so that the projection 82 may enter the slot portion 85 when aligned therewith under the influence of the spring 68. That is the cam member 103 is positioned as shown in Figure 6. In this position it does not engage the pawl 80. The cam member 103 is moved further in the direction of the arrow 105 to cause the cam member 103 to engage the bar 75 and move the bar 75 so that again it is located between 20 the projection 103 and the wall 54, thus preventing movement of the handle 17. To again enable operation of the lock 10, the key 104 is moved in the opposite angular direction so that the cam member 103 moves in a direction opposite the direction 105. The cam member 103 engages the pawl 80 and pivots the pawl 80 to the position shown in Figure 1. Thus the pawl 80 has its projection 82 aligned with the slot portion 85. Further 25 movement of the cam member 103 causes the cam member 103 to engage the bar 75 and moves the bar 75 in a direction opposite the arrow 77 so that the bar 75 is no longer located between the projection 105 and the wall 54. Accordingly the handle 17 is again free for movement.

12 The bar 60 may extend beyond the lock 10 so as to operate remote lock tongues so that the door is secured closed in a number of spaced locations. For example at the spaced locations there would be an equivalent of the eyelet 58 and an equivalent of the pin 55. 5 It should be appreciated the lever 91 merely abuts the bar 62 and can move away from the bar 62 in a direction opposite the direction 93 so that the handle 17 can move to the next position without moving the pin 55. The same can be said for the arm 90 and lever 91.
