Patent ID: 7992832

Claim:
A mounting mechanism comprising: an initial bar and a second bar that are each mounted via hinges at either end thereof such that the initial and second bars are constrained to remain parallel to one another, wherein the initial and second bars are configured to translate relative to each other when a pitch of the initial and second bars is adjusted, a stopping block mounted on the second bar, the stopping block comprising a guiding wall and a stopping slot formed through the guiding wall; a stopping pin mounted on the initial bar, wherein the stopping pin is sized to be received within the stopping slot; and an actuating member configured to transition between a locking position and an unlocking position, wherein, when the actuating member is in the locking position, the stopping pin is configured to slide on the guiding wall until a predetermined position of the mounting mechanism is reached, and wherein, when the predetermined position is reached, the stopping pin is automatically received within the stopping slot of the stopping block so as to prevent translational movement of the initial and second bars relative to each other, and wherein, when the actuating member is in the unlocking position, the stopping pin is prevented from being received within the stopping slot such that the initial and second bars are able to translate relative to each other past the predetermined position of the mounting mechanism.
