Abstract

An automatic gate arm damage prevention system includes a lift arm that is coupled to a lifting apparatus. The lift arm has an outer end, an upper side, a lower side, a first lateral side and a second lateral side. A channel extends into the outer end and the upper side so that the channel is bounded by the first and second lateral sides and the lower side. An elongated member has a first end and a second end. The first end is positioned in the channel. A pivot pin extends through the channel and through the elongated member and the lift arm to pivotally couple the elongated member to the lift arm. The second end is pivotable upwardly with respect to the lift arm.

Claims

1. A gate arm assembly to inhibit damage to a vehicle, said assembly including:

a lift arm being coupled to a lifting apparatus, said lift arm having an outer end, said lift arm having an upper side, a lower side, a first lateral side and a second lateral side, a channel extending into said outer end and said upper side so that said channel is bounded by said first and second lateral sides and said lower side; and

an elongated member having a first end and a second end, said first end being positioned in said channel, a pivot pin extending through said channel and through said elongated member and said lift arm to pivotally couple said elongated member to said lift arm, said second end being pivotable upwardly with respect to said lift arm, wherein said elongated member is vertically movable upwardly when said lift arm is moved vertically downward by said lifting apparatus; and

wherein said elongated member has a break therein positioned nearer to said first end than said second end to define a first section and a second section of said elongated member, said first section including said first end and being only pivotable in a vertical direction, said first section having a distal end with respect to said lift arm, a pair of supports being attached to said distal end and extending outwardly therefrom to define a receiving slot positioned between said supports, said supports being vertically spaced from each other, said second section including a proximal end with respect to said lift arm, said proximal end being positioned within said receiving slot, a pivot rod extending through said supports and said second section to allow said second section to laterally pivot with respect to said first section.

2. The assembly according to claim 1, further including a stop being attached to said second section to restrict pivoting of said second section to only a first direction away from a straight line extending through said first and second ends when said first section is aligned with said second section.

3. The assembly according to claim 1, further including a biasing member being mounted to said first and second sections and biasing said second section into alignment with said first section.

4. A gate arm assembly to inhibit damage to a vehicle, said assembly including:

a lift arm being coupled to a lifting apparatus, said lift arm having an outer end, said lift arm having an upper side, a lower side, a first lateral side and a second lateral side, a channel extending into said outer end and said upper side so that said channel is bounded by said first and second lateral sides and said lower side;

an elongated member having a first end and a second end, said first end being positioned in said channel, a pivot pin extending through said channel and through said elongated member and said lift arm to pivotally couple said elongated member to said lift arm, said second end being pivotable upwardly with respect to said lift arm, wherein said elongated member is vertically movable upwardly when said lift arm is moved vertically downward by said lifting apparatus;

said elongated member having a break therein positioned nearer to said first end than said second end to define a first section and a second section of said elongated member, said first section including said first end and being only pivotable in a vertical direction, said first section having a distal end with respect to said lift arm, a pair of supports being attached to said distal end and extending outwardly therefrom to define a receiving slot positioned between said supports, said supports being vertically spaced from each other, said second section including a proximal end with respect to said lift arm, said proximal end being positioned within said receiving slot;

a pivot rod extending through said supports and said second section to allow said second section to laterally pivot with respect to said first section;

a stop being attached to said second section to restrict pivoting of said second section to only a first direction away from a straight line extending through said first and second ends when said first section is aligned with said second section; and

a biasing member being mounted to said first and second sections and biasing said second section into alignment with said first section.
