Latch for oven door

Abstract

A latch for an oven door is provided. The latch includes a bar defined within a frame of the oven and a door rotatably mounted to the frame. A latch arm is pivotably mounted to the door and a handle is pivotably mounted to the door by an operator. The latch arm engages the bar in a first position of the handle with respect to the door.

1 . An oven, comprising:
 a cooking compartment partially defined by a frame with an inlet opening, wherein a periphery of the cooking compartment comprises a bar;   a pivotable door engageable with the frame to fully enclose the cooking compartment, comprising a pivotable latch arm and a handle;   a first pin pivotably connected to the latch arm and the handle; and   a second pin that extends parallel to the first pin and through a slot in the latch arm;   wherein the latch arm and the handle are pivotably connected by the first pin and the latch arm is pivotable by pivoting the handle with respect to the door.   
   
   
       2 . The oven of  claim 1 , wherein the connection between the slot and the second pin defines a range of relative motion between the handle and the latch arm. 
   
   
       3 . The oven of  claim 2 , wherein the latch arm further comprises a finger extending therefrom to provide pivotable contact with the bar. 
   
   
       4 . The oven of  claim 1 , wherein the first pin extends from an operator fixed to the handle. 
   
   
       5 . The oven of  claim 1 , further comprising a biasing member arranged to bias the latch arm against the frame to prevent the door from rotating with respect to the cooking compartment. 
   
   
       6 . The oven of  claim 3 , wherein the finger comprises a chamfered edge and a locking edge. 
   
   
       7 . The oven of  claim 6 , wherein the locking edge contacts the bar in a latching position. 
   
   
       8 . The oven of  claim 6 , wherein the latch arm is mounted on the door such that the chamfered edge contacts the bar as the door is rotated from an open position to a latching position. 
   
   
       9 . The oven of  claim 8 , wherein the latch arm is operative to pivot when the chamfered edge contacts the bar and allow the interior surface of the door to engage the frame of the oven. 
   
   
       10 . The oven of  claim 1 , comprising a first latch arm pivotably mounted proximate a top surface of the door and a second latch arm pivotably mounted proximate a bottom surface of the door. 
   
   
       11 . The oven of  claim 10 , wherein the handle is pivotable with respect to the first and second latch arms. 
   
   
       12 . The oven of  claim 1 , wherein the handle is operatively connected to the first pin with one of a spline, a keyed connection, or a weld. 
   
   
       13 . The oven of  claim 1 , wherein the latch arm, the first and second pins, and an operator connecting the first pin to the handle comprises a modular assembly removeably attachable to the door with a fastener. 
   
   
       14 . A latch for an oven door, comprising:
 a bar defined within a frame of the oven;   a door rotatably mounted to the frame;   a latch arm pivotably mounted to the door;   a handle pivotably mounted to the door; and   a pin constrained with the handle and extending through the slot in the latch arm,   wherein the latch arm is configured to engage the bar in a first position of the handle and to rotate free of the bar in a second position of the handle, and wherein contact between the pin and the slot defines a range of travel of the latch arm with respect to the handle.   
   
   
       15 . The latch of  claim 14 , wherein the latch arm, the pin, and an operator for connecting the pin to the handle comprises a modular assembly configured to be attached to and removed from the door with a fastener. 
   
   
       16 . The latch of  claim 14 , further comprising a second latch arm rotatable about the door, wherein rotation of the handle causes similar rotation of the first and second latch arms. 
   
   
       17 . The latch of  claim 14 , wherein the latch arm comprises a finger with a chamfered edge and a locking edge, wherein the chamfered edge contacts the bar as the door rotates from an open position to a closed position, causing the latch arm to rotate and clear the bar and allow the door to reach the closed position. 
   
   
       18 . The latch of  claim 17 , wherein the locking edge contacts the bar when the door reaches the closed position.
