A latching mechanism which is primarily intended for use with hung and sliding window systems. The latching mechanism includes a body 10 and latch element 25, the latch element being moveable between a latching position and a non-latching position. The latch element 25 is coupled to a slider 36 which is moveable by an operating slide 13 mounted with lock furniture 11. The slide element 13 is coupled to the slider 36 by a lost motion member 34 which is operable to release a snap hook from engagement with the slider 36 prior to the slider 36 being moved from its latching position.

1. A latching mechanism including a body, a latch element movable between a latching position and a non-latching position, a slider retained for rectilinear motion within the body for causing movement of the latch element between said latching and non-latching positions, a retainer for retaining the slider when the latch element is in said latching position, said retainer being biased to engage with an engagement part of the slider when the slider moves to said latching position to retain said slider in the latching position, an operating member external of the body and coupled to the slider via a lost motion connection between the operating member and slider whereby in use the operating member imparts movement to the slidably to disengage the retainer from the engagement part and thereby release the slider such that movement of the slider can occur.2. A latching mechanism as claimed in claim 1 wherein the lost motion connection is a release member movably mounted with the slider, said release member including an engagement surface which is engageable with the retainer to move the retainer from engagement with the engagement part of the slider.3. A latching mechanism as claimed in claim 2 further including a second retainer for retaining the moving mechanism when the latch element is in the non-latching position.4. A latching mechanism as claimed in claim 3 wherein the second retainer is engageable with a second engagement part of the slider, said release member having a second engagement surface engageable with the second retainer to release the second retainer from the slider in response to movement of the operator.5. A latching mechanism as claimed in claim 1 further including an anti-slam mechanism.6. A latching mechanism as claimed in claim 5 wherein the anti-slam mechanism is a pin which is biased to project from the body and lockingly engaged with a contact part of the slider when the slider is in the non-latching position, the pin having a clearance which aligns with the contact part of the slider to release the slider when the pin is moved from its projecting position.7. A latching mechanism as claimed in claim 1 where the latch element is a roller element.8. A latching mechanism as claimed in claim 7 in combination with a strike, the strike including a cam profile engageable with the roller element as the roller element moves to and from the latching and non-latching positions.9. A latching mechanism as claimed in claim 8 wherein the body includes at least one projecting cleat and the strike includes a reception area for receiving the cleat when the strike and body are in relative positions which in use corresponds to a closure member with which the latching mechanism is mounted having been moved to a closed position.10. A latching mechanism including a body, a latch element movable between a latching position and a non-latching position, a moving mechanism for causing movement of the latch element between said latching and non-latching positions, a retainer for retaining the moving mechanism when the latch element is in said latching position, latch furniture with which is slidably mounted a slide element the slide element being coupled to the moving mechanism via a lost motion connection between the slide element and moving mechanism whereby in use the slide element causes release of the retainer to enable movement of the moving mechanism to occur.11. A latching mechanism as claimed in claim 10 wherein the cover includes indicators to indicate that the latch element is in the latching and non-latching positions, said slide element covering a respective one of the indicators depending on whether the latch element is in the latching or non-latching position.12. A latching mechanism as claimed in claim 10 wherein the body includes a retention device to retain the body in a section of a frame when the body has been installed through a first opening and into the interior of the frame section.13. A latching mechanism as claimed in claim 12 wherein the body includes a pair of spaced apart feet which in use engage with a perimeter surface of a second opening in the frame section, said second opening being disposed opposite said first opening.14. A latching mechanism as claimed in claim 10 in combination with a window frame, said window frame including a pair of oppositely disposed openings, the body being located through a first opening into the interior of the frame, the body having a pair of feet which engage with the frame at the periphery of a second opening and snap fit fastener elements which engage with the said one opening.15. The combination of claim 14 wherein the openings are of substantially the same dimensions.16. The combination of claim 15 wherein the snap fit fastener comprises one or more spring legs which are formed as an integral part of the body.17. The combination of claim 14 wherein a part of the body which engages with the second opening includes a plurality of ribs which are substantially transverse to the plane of the second opening.18. A latching mechanism in combination with a strike the latching mechanism including a body, a latch element in the form of a roller element movable between a latching position and a non-latching position, the strike including a cam profile engageable with the roller element as the roller element moves to and from the latching and non-latching positions, a moving mechanism for causing movement of the latch element, a retainer for retaining the moving mechanism when the latch element is in said latching position, a slide element slidably mounted with a cover which is coupled to the body, the slide element being coupled to the moving mechanism via a lost motion connection between the slide element and moving mechanism whereby in use the slide element causes release of the retainer to enable movement of the moving mechanism to occur, the body including at least one projecting cleat and the strike includes a reception area for receiving the cleat when the strike and body are in relative positions which in use corresponds to a closure member with which the latching mechanism is mounted having been moved to a closed position.19. A latching mechanism including a body which has a retention device to retain the body in a section of a frame when the body has been installed through a first opening and into the interior of the frame section, and a pair of spaced apart feet which in use engage with a perimeter surface of a second opening in the frame section, said second opening being disposed opposite said first opening, the latching mechanism further including a latch element movable between a latching position and a non-latching position, a moving mechanism for causing movement of the latch element between said latching and non-latching positions, a retainer for retaining the moving mechanism when the latch element is in said latching position, a slide element slidably mounted with a cover which is coupled to the body, the slide element being coupled to the moving mechanism via a lost motion connection between the slide element and moving mechanism whereby in use the slide element causes release of the retainer to enable movement of the moving mechanism to occur.
