In an actuating mechanism for a double bar lock of the type having first and second bars slidably mounted in a housing for movement between a locked position wherein each of said bars extend outwardly from opposite sides of said housing and an unlocked position wherein said bars are moved inwardly towards each other, and driving means effective to move one of the bars in a given direction in response to the movement of the other of said bars in the opposite direction such that the movement of one bar between the locked and unlocked positions moves the other bar between said positions, the improvement which comprises moving means comprising a first and a second rotatable cam spaced from each other and rotatable in the same plane, said moving means being operably connected to said first bar and effective when actuated to move said first bar between the locked and unlocked positions, a recess on said first bar, and deadlocking means external to said first bar and movable between a first position wherein said recess is operably engaged by said deadlocking means to prevent the movement of said first bar and a second position wherein said recess is operably disengaged by said deadlocking means to permit movement of said first bar, said deadlocking means being moved between said first and second positions by actuation of said moving means, said deadlocking means comprising a movable member having a pair of cam followers mounted thereon, each of said cam followers being operatively engageable with a different one of said cams such that said member is moved between said first and second positions by rotation of either of said cams.
Claim 2
Dependent Claim
277 words
In an actuating mechanism for a double bar lock of the type having first and second bars slidably mounted in a housing for movement between a locked position wherein each of said bars extend outwardly from opposite sides of said housing and an unlocked position wherein said bars are moved inwardly towards each other, and driving means effective to move one of the bars in a given direction in response to the movement of the other of said bars in the opposite direction such that the movement of one bar between the locked and unlocked positions moves the other bar between said positions, the improvement which comprises moving means comprising a first and a second rotatable cam spaced from each other and rotatable in the same plane, said moving means being operably connected to said first bar and effective when actuated to move said first bar between the locked and unlocked positions, a recess on said first bar, and deadlocking means external to said first bar and movable between a first position wherein said recess is operably engaged by said deadlocking means to prevent the movement of said first bar and a second position wherein said recess is operably disengaged by said deadlocking means to permit movement of said first bar, said deadlocking means being moved between said first and second positions by actuation of said moving means, said deadlocking means comprising a movable member having a pair of cam followers mounted thereon, each of said cam followers being operatively engageable with a different one of said cams such that said member is moved between said first and second positions by rotation of either of said cams.
