Abstract
Embodiments described herein relate to an exit device having a construction that facilitates visual inspection of the state of the exit device. Embodiments of the exit device include a visual indicator as to the state (dogged or undogged) of the exit device.
Claims20
An exit device comprising:
- a housing;
- a push bar operatively coupled to the housing and moveable between an extended position and a depressed position, the push bar having a proximal surface;
- a latch operatively coupled to the push bar such that actuation of the push bar from the extended position to the depressed position causes the latch to move from the latched or extended position to an unlatched or retracted position;
- a latch region housing that houses the latch, the latch region housing having a proximal surface;
- an end region housing located at an end opposite the latch region housing, the end region housing having a proximal surface;
- and,
- a push bar region housing located between the end region housing and the latch region housing,
- wherein, when the exit device is in an undogged state where the push bar is in the extended position, the proximal surface of the push bar effectively aligns with the proximal surface of the end region housing and wherein, when the exit device is in the dogged state where the push bar is in the depressed position, the proximal surface of the push bar effectively aligns with the proximal surface of the latch region housing.

An exit device comprising:
- a housing;
- a push bar operatively coupled to the housing and moveable between an extended position and a depressed position;
- an end region housing;
- a push bar region housing located adjacent the end region housing;
- and,
- a mid-transition region located between the end region housing and the push bar region housing, the mid-transition region including a surface, wherein when the exit device is in the undogged state, the surface of the mid-transition region is visually effectively concealed and wherein when the exit device is in the dogged state, the mid-transition region surface is visually exposed, with the mid-transition region surface being colored with a color contrasting with adjacent portion of the exit device.
