ABSTRACT:
A door latch particularly for use in mobile homes or recreational vehicles. A housing having a channel formed therein is mounted on one surface of a door overlying a passageway therethrough. A spring-loaded slidable latch engagement member is positioned within the channel for operating engagement with a striker plate mounted on the jamb of the frame against which the door abuts when closed. A latch retaining pin is positioned through the housing and has a shaft part extending within the passageway in the door for receipt on the other side of the door surface of an operating knob or handle secured thereon. Rotation of the operating knob actuates the pin to disengage the latch engagement member and thereby unlatch the door. A lockable abutment member may be positioned upon the door surface or an extension part of the housing to block the path of the latch engagement member when moved toward disengagement position and thereby prevent such disengagement.
In an alternate embodiment a concealed latch is disclosed in which the latch engagement member has a lateral extension disposed in a space formed in the door and opening to the door edge such that a force applied to the extension member will disengage the latch engagement member.
