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.

A door latch for latching a door to its associated jamb, the door having a channel therein opening to an edge surface thereof, said latch comprising, a housing of generally rectangular configuration with a top surface and an undersurface and being mountable on one surface of the door overlying said channel with the undersurface facing said one surface of the door, a channel formed in the undersurface along the elongate dimension of the housing, a latch engagement member having an opening formed therein and retained within the housing, cooperative means on said channel and said latch engagement member to permit slidable movement of the latch engagement member in the channel, means on the latch engagement member for cooperative engagement with a striker plate mounted on the jamb, an aperture passing through the housing and opening at one end thereof to the top surface and at the other end thereof to the channel in the housing, a retaining pin positioned through the aperture in the housing and the opening in the latch engagement member, spring means positioned in the housing to bias the latch engagement member so that at least a portion of said latch engagement member normally is disposed out of the housing and engaged with the striker plate, said retaining pin having a flat surface thereon engaged against one wall of the opening in the latch engagement member to prevent the latch engagement member from leaving the housing, the latch engagement member including a lateral extension disposed within the door channel and terminating proximate the edge surface of the door so as to be substantially flush therewith, said extension being operable upon exertion of a force thereagainst to move the latch engagement member against the force of the spring means and thereby disengage the member from the striker plate to permit unlatching of the door, and including a generally square-shaped compartment formed in the housing beneath the top surface, said compartment opening to a front surface of the housing and to the channel in the housing, and an abutment wall formed in the compartment on a side thereof opposite the front surface of the housing, said spring means being located in said square-shaped compartment and acting against said abutment wall.
