ABSTRACT:
An adapter for coupling an actuator having an actuator rod that is linearly translatable along a first axis to a coupler having a lever arm with a contact face adapted to contact the draw arm and move the draw arm translationally along a second axis that is at an angle with respect to the first axis in the range of 1 degree to 120 degrees, the coupler mounted to an existing structure, the adapter including a base plate configured for attachment to the structure; a support plate depending from the base plate and adapted to receive the pneumatic actuator; at least one brace attached to the base plate and to the support plate; and a rotatable cam adapted to transfer force from the actuator rod as it moves along the first axis to the lever arm to cause the draw arm to move along the second axis and into contact with the hook on the coupler.
