摘要： A tilt latch (10) for a sash window (12) has a bolt stop. The sash window (12) is disposed within opposed guide rails (16) on a master frame (14). The sash window (12) is comprised of a top sash rail (20), a base (22) and two stiles (24,26) connected together at their extremities. The tilt-latch (10) is adapted for releasably securing the sash window (12) to the master frame (14). The tilt-latch (10) is comprised of a housing (42) adapted to be supported by the top rail (20). The housing (42) has an outward end opening (44). A latch bolt (46) is disposed within the housing (42) and has a nose adapted for engaging a respective one of the guide rails (16). A protrusion (80) is located either on the latch bolt (46) or the housing (42) and a lock wall (86) is located either on the housing (42) or the latch bolt (46). The protrusion (80) has a stop surface (84) and is moveable between a first position defining a prevent position (94) wherein the stop surface (84) is adapted to abut the lock wall (86) to prevent retraction of the latch bolt (46) into the housing (42), and a second position defining a deflected position (96) wherein the stop surface (84) does not abut the lock wall (86) to allow retraction of the latch bolt (46) into the housing (42). The protrusion (80) is biased to the prevent position.
摘要翻译：用于窗扇（12）的倾斜闩（10）具有螺栓挡块。窗扇（12）设置在主框架（14）上的相对的导轨（16）内。窗扇（12）包括在其四肢连接在一起的顶部窗框（20），基座（22）和两个台阶（24,26）。倾斜闩锁（10）适于将窗扇（12）可释放地固定到主框架（14）。倾斜闩锁（10）包括适于由顶部轨道（20）支撑的壳体（42）。外壳（42）具有外端开口（44）。闩锁螺栓（46）设置在壳体（42）内并且具有适于接合相应的一个导轨（16）的鼻部。突起（80）位于闩锁螺栓（46）或壳体（42）上，并且锁定壁（86）位于壳体（42）或闩锁螺栓（46）上。突起（80）具有止动表面（84），并且可在限定防止位置（94）的第一位置和第二位置之间移动，其中止动表面（84）适于抵靠锁定壁（86），以防止闩锁螺栓（46）进入所述壳体（42），以及限定偏转位置（96）的第二位置，其中所述止动表面（84）不抵靠所述锁定壁（86）以允许所述闩锁螺栓（46）缩回到所述壳体（42）。突起（80）被偏压到防止位置。

摘要： A window stop (10) for limiting movement of a sliding window along a predetermined path of window movement is provided. The window stop (10) has a housing (12) having a cavity (20) wherein the housing (12) is adapted to be positioned adjacent the path of window movement. A bolt (14), operatively associated with the cavity (20), is moveable between a first position (BP1) within the housing (12) and thereby out of the path of window movement, and a second position (BP2) extending out of the housing (12) into the path of the window movement whereby the window is able to contact the bolt (14). An actuator (16) is pivotally supported by the bolt (14) between a first position (AP1) locking the bolt (14) within the housing (12) and a second position (AP2) allowing the bolt (14) to extend to its second position (BP2). A spring (58) biases the bolt toward its second position. The bolt (14) receives forces from the window contacting the extended bolt (14). A tongue and groove arrangement is provided to allow efficient distribution of forces from the bolt (14) to the housing (12).
