Abstract
An apparatus for controlling the movement of a movable tail-gate hinged to a tipping body of a vehicle. A collapsible toggle linkage is pivotally connected at one end to a flap adapted to bear against the tail-gate and the opposite end of the linkage is pivotally connected to a support secured to the vehicle. The toggle linkage is moved between erect and collapsed conditions by a piston and cylinder assembly, the piston rod of said assembly being connected to the interconnected ends of the toggle linkage by a bracket. The bracket serves as a stop to prevent outwardly collapsing movement of the toggle linkage. The tail-gate can be maintained in a closed position independently of any forces exerted by the piston and cylinder assembly.
Claims11
An apparatus for controlling the movement of a tail-gate of a vehicle body, comprising:
- a support securable to the vehicle body adjacent and below the tail-gate;
- a flap adapted to bear against the tail-gate;
- a collapsible linkage having first and second arms pivotally interconnected on a pivot axis at their one ends to form a toggle, the opposite ends of the arms pivotally connected to the flap and to the support respectively;
- actuating means operable to swing the flap between first and second positions for both opening and closing the tail-gate respectively;
- and
- a bracket operatively connecting the actuating means to the linkage, the bracket including means responsive to said pivot axis being immediately on the side of a line joining the opposite ends of the arms remote from the actuating means for preventing collapse of said toggle.
An apparatus for controlling the movement of a tail-gate of a vehicle body, comprising;
- a support securable to the vehicle body adjacent and below the tail-gate, said support having two laterally spaced rigid plates aligned in planes transverse to the tail-gate, said plates having substantially rearward facing edge means for engaging and supporting the opened tail-gate;
- a flap pivoted between said support plates and extending therefrom to supportively bear against the tail-gate;
- a collapsible linkage having first and second arms with adjacent ends pivotally interconected on a pivot axis to form a toggle, the remote end of said first arm being pivotally connected to said flap, the remote end of said second arm being pivoted between said support plates, the support plate pivots of said flap and second arm defining a plane transverse to said plates, said arms having a collapsed tail-gate open position with the pivotally interconnected adjacent ends thereof spaced in one direction from said plane and having a straightened tail-gate closed position spaced in the opposite direction from said plane;
- and
- an actuating means engaging said toggle linkage between said plates and reversibly actuable for pivoting said arms from said straightened tail-gate closed position to said collapsed tail-gate open position and vice versa.
