Abstract
In a gate, a stile (20) and rail (21) abut side face to end face and are held together by a bolt passing at right angles through the end face to pull against a plate (25) located in a slot (26). Straps (34,41), see FIGS. 11 and 13, are used to reinforce the hanging and shutting stiles (20,20A) and to carry hanging and latching parts. A latching mechanism, see FIGS. 13 to 16, includes a latching bar (43) that is pivotally connected to the shutting stile (20) towards its middle by a flange (44). A leaf spring (45) urges the bar (43) into a latching position at which, when the gate is shut, the bar (43) is caught behind upper and lower retainers (46) mounted on a shutting gatepost (48). By pulling on a handle (50), the bar (43) can be rocked free of the retainers (46) to permit the gate to be opened. Connector plates ( 31) having sharp tongs are used, see FIGS. 9 and 10, with bolts to connect reinforcing struts (30) to the upper and lower rails (21,21A). Upper and lower hinge brackets for mounting on a hanging gatepost are also provided, see FIGS. 17 to 23.
