Abstract

A new latch device for a screen door includes inside and outside handle assemblies. Each assembly has a lever adapted to be pivotably connected, respectively, to the inboard and outboard side of the screen door. The inboard lever has a paddle at one end and a stem at the other. The stem extends through an opening formed in the screen door. When the paddle is depressed, the stem moves along a cam surface formed in the outboard lever. This causes the outboard lever to disengage the fastener on the solid door to disconnect the solid door from the screen door. Additionally, when the screen door is in its latched position and not connected to the solid door, depressing the paddle causes the latching end of the outboard lever to disengage the doorjamb so that the screen door can be moved independently from its latched position into its open position.

Dependent claims

A latch device for a screen door, the screen door is hingedly supported in a doorjamb and releasably connected to a solid door also hinged supported in the door jamb the doors are movable together as a single unit or independently of each other between respective latched and open positions, a handle assembly connected to an outboard side of the screen door is adapted to releasably connect the screen door and the solid door the latch device comprising:

an inboard handle assembly for mounting on an inboard side of a screen door, the inboard handle assembly includes
an inboard lever having opposite ends with a stem at one end and
a paddle at the other end, the inboard lever is adapted to be pivotably connected to the inboard side of the screen door so that the stem passes through the screen door to the outboard side of the screen door;
and
an internal cam surface formed inside a cutout of an outboard lever pivotably supported by a handle assembly connected to the outboard side of the screen door for receiving the stem of the inboard handle assembly, and for guiding movement of the stem when force is applied to the paddle of the inboard lever;
and
a fastener positioned between the solid door and the screen door adapted for engagement with the outboard lever for releasably securing the screen door and the solid door together.

A latch device for a screen door, the screen door is hingedly supported in a doorjamb and releasably connected to a solid door also hingedly supported in the doorjamb, the doors are movable independently of each other or together as a single unit between a latched position and an open position, the latch device comprising:

inside and outside handle assemblies each having a lever adapted to be pivotably connected, respectively, to the inboard and outboard side of the screen door, each lever includes a pivot axis, the outside lever further comprising a forward end, a latching end for engagement with the doorjamb, and a sloped portion between the forward and latching ends for engaging a fastener on a solid door, the outside lever further comprising a cutout having an internal cam surface;
and
a fastener on the inboard side of the solid door for releasably engaging the sloped portion of the outside lever to secure the screen door and the solid door together,
wherein when one end of the inside handle assembly lever is depressed, the lever pivots, and a terminal end portion of said lever moves along the cam surface moving the outboard lever so that the outboard lever disengages the fastener on the solid door to disconnect the solid door from the screen door.
