Abstract

A slide latching system for latching a sliding door panel to a door frame includes a jamb strike, a latch assembly, and a handle set. The jamb strike is connected to the door frame. The latch assembly is connected to the sliding door panel, and has a latch member having a latch hook portion configured to engage the jamb strike. The latch hook portion is movable between a latched position and an unlatched position. The handle set is mounted to the sliding door panel. The handle set is drivably coupled to the latch assembly. The handle set is configured to facilitate both of a moving of the latch hook portion of the latch assembly to the unlatched position and a sliding of the sliding door panel in a first direction in a continuous motion applied to the handle set by a user.

First claim

What is claimed is:

1 . A slide latching system for latching a sliding door panel to a door frame, comprising:
a jamb strike is connected to the door frame; a latch assembly connected to the sliding door panel, the latch assembly having a latch member having a latch hook portion configured to engage the jamb strike, the latch hook portion being movable between a latched position and an unlatched position; and a handle set mounted to the sliding door panel, the handle set being drivably coupled to the latch assembly, the handle set configured to facilitate both of a moving of the latch hook portion of the latch assembly to the unlatched position and a sliding of the sliding door panel in a continuous motion applied to the handle set by a user.

2 . The slide latching system of claim 1 , the latch assembly having a latch housing, a rotary actuator, and the latch member, the rotary actuator defining a latch pivot axis, the latch member having a latch hook portion configured to engage the jamb strike, the latch member being drivably coupled to the rotary actuator such that the latch member and the rotary actuator pivot in unison, the latch hook portion being movable between a latched position and an unlatched position; and
the handle set being drivably coupled to the rotary actuator of the latch assembly.

3 . The slide latching system of claim 2 , the handle set comprising a base, a cam, and an exterior handle,
the cam being rotatably mounted to the base to pivot about a cam axis, the cam axis being oriented to be substantially horizontal, the cam including a barrel having a driver end portion and a cam arm having a driven end portion, the driver end portion being drivably engaged with the rotary actuator of the latch assembly, the handle being rotatably mounted to the base plate to pivot about a handle axis, the handle axis being oriented to be substantially vertical, the handle having a cam driver that is slidably engaged with the driven end portion of the cam arm of the cam, wherein a pivoting of the handle about the handle axis causes a corresponding rotation of the cam about the cam axis to effect a movement of the latch hook portion of the latch assembly from the latched position to the unlatched position.

4 . The slide latching system of claim 3 , the handle set including a biasing member that pivots the handle in a first rotary direction to position the handle in a home position, and wherein the user pulls the handle in the first direction to pivot the handle in a second rotary direction to an actuated position about the handle pivot axis, the second rotary direction being opposite to the first rotary direction.

5 . The slide latching system of claim 3 , wherein when the handle is in the home position, the handle is oriented at an acute angle relative to a planar extent of the sliding door panel, and when the handle is in the actuated position, the handle is oriented to be substantially parallel to the planar extent of the sliding door panel.

6 . The slide latching system of claim 5 , wherein the acute angle is approximately 85 degrees.

7 . The slide latching system of claim 2 , wherein the base plate of the handle set includes an upper pivot arm and a lower pivot arm, the handle being positioned between the upper pivot arm and the lower pivot arm, and the handle being pivotably coupled to each of the upper pivot arm and the lower pivot arm.

8 . The slide latching system of claim 3 , wherein the base plate has a cam mounting hole configured to receive the barrel of the cam, the barrel extending through the cam mounting hole such that the driver end portion engages the rotary actuator of the latch assembly.

9 . The slide latching system of claim 8 , wherein the cam arm extends substantially orthogonally from the barrel.

10 . The slide latching system of claim 1 , wherein the jamb strike includes a body having an upper strike catch, a lower strike catch, and a cavity between the upper strike catch and the lower strike catch, the cavity extending into the body and behind each of the upper strike catch and the lower strike catch.

11 . The slide latching system of claim 10 , wherein the latch hook portion of the latch member of the latch assembly operably engages only the upper strike catch, and when the upper strike catch experiences an amount wear that is no longer acceptable, then the jamb strike is inverted such that the lower strike catch becomes a new upper strike catch.

12 . The slide latching system of claim 10 , wherein the jamb strike is made from nylon material.

13 . The slide latching system of claim 1 , wherein the handle set is an exterior handle set mounted to an exterior side of the sliding door panel, and further including:
an interior handle set mounted to the interior side of the sliding door panel, the interior handle set being configured as a mirror image of the exterior handle set and configured to facilitate a moving of the latch hook portion of the latch assembly to the unlatched position and a sliding of the sliding door panel in an interior-side continuous motion applied by a user.
