Claim 10
Dependent Claim
61 words
The vehicle restraint of claim 7, wherein said biasing means includes a resilient member interconnected between said frame means and said restraining means, and adjusting means for adjusting the location of the pivotal connection of said resilient member to one of said frame means and said restraining means, whereby said biasing means can be moved between said first and second positions.
Claim 11
Dependent Claim
71 words
The vehicle restraint of claim 8, wherein one end of said resilient member is pivotally connected to said restraining means, a link having a first end pivotally connected to the opposite end of said resilient means and said link having a second end pivotally connected to said frame means, pivotal movement of said link relative to said frame means acting to move said resilient member between the first and second positions.
Claim 12
Dependent Claim
193 words
A vehicle restraint to prevent a vehicle from moving away from a fixed object, comprising a supporting structure to be mounted on a generally vertical face of a fixed object, restraining means mounted for pivotal movement in a generally vertical plane about a horizontal axis extending normal to said face between a first storage position and a second operative position, said restraining means comprising a first member having an inner end journalled for rotation about said horizontal axis, a second member connected to the outer end portion of said first member and extending outwardly in a direction away from said supporting structure, said restraining means also including a third member connected to the outer end of said second member and extending vertically upward from said second member, said second member being constructed and arranged to engage the lower surface of an element on said vehicle as said restraining means is pivoted from said storage position to said operative position, and said third member being constructed and arranged to be disposed outwardly of said element when said restraining means is in the operative position to prevent movement of said vehicle away from said object.
Claim 13
Dependent Claim
193 words
A vehicle restraint to prevent a vehicle from moving away from a fixed object, comprising a supporting structure to be mounted on a generally vertical face of a fixed object, restraining means mounted for pivotal movement in a generally vertical plane about a horizontal axis extending normal to said face between a first storage position and a second operative position, said restraining means comprising a first member having an inner end journalled for rotation about said horizontal axis, a second member connected to the outer end portion of said first member and extending outwardly in a direction away from said supporting structure, said restraining means also including a third member connected to the outer end of said second member and extending vertically upward from said second member, said second member being constructed and arranged to engage the lower surface of an element on said vehicle as said restraining means is pivoted from said storage position to said operative position, and said third member being constructed and arranged to be disposed outwardly of said element when said restraining means is in the operative position to prevent movement of said vehicle away from said object.
