A tail-gate assembly comprising; (a) a stationary support, (b) slide means slidably mounted on said stationary support for movement between a raised position and a lowered position, (c) a platform pivotally mounted on said slide means for movement in a first direction between a horizontal position and an upright position and movement in a second direction between the upright position and the horizontal position, (d) platform pivoting means normally urging said platform in said first direction towards said upright position, (e) a latch member mounted on and projecting laterally from said loading platform, (f) a latch plate mounted on said stationary support, said latch plate having a latch notch formed therein which has an entrance way opening in a direction opposite said first direction to admit said latching member to said notch, said notch being proportioned to receive said latch member in a close fitting relationship so as to provide a vertical restraint limiting vertical movement and a rotational restraint limiting rotational movement of said platform, (g) a pair of latching jaws each having a locking tooth at one end thereof, said jaws being mounted on said latch plate for pivotal movement between a closed position in which the locking teeth extend inwardly from opposite sides of said entrance way to prevent withdrawal of the latching member from said notch and an open position in which the teeth are displaced outwardly from said entrance way to admit and release the latching member, (h) closure means engaging said jaws and normally urging said jaws towards said closed position, said closure means being adapted to yield to permit said jaws to open in response to contact with the latch member as it is moved in said first direction under the influence of said platform pivoting means, (i) actuator means on said jaws adapted to interact with one another whereby movement of one jaw toward the open position causes movement of the other jaw toward the open position.

A tail-gate assembly comprising; (a) a stationary support, (b) slide means slidably mounted on said stationary support for movement between a raised position and a lowered position, (c) a platform pivotally mounted on said slide means for movement in a first direction between a horizontal position and an upright position and movement in a second direction between the upright position and the horizontal position, (d) platform pivoting means normally urging said platform in said first direction towards said upright position, (e) a latch member mounted on and projecting laterally from said loading platform, (f) a latch plate mounted on said stationary support, said latch plate having a latch notch formed therein which has an entrance way opening in a direction opposite said first direction to admit said latching member to said notch, said notch being proportioned to receive said latch member in a close fitting relationship so as to provide a vertical restraint limiting vertical movement and a rotational restraint limiting rotational movement of said platform, (g) a pair of latching jaws each having a locking tooth at one end thereof, said jaws being mounted on said latch plate for pivotal movement between a closed position in which the locking teeth extend inwardly from opposite sides of said entrance way to prevent withdrawal of the latching member from said notch and an open position in which the teeth are displaced outwardly from said entrance way to admit and release the latching member, (h) closure means engaging said jaws and normally urging said jaws towards said closed position, said closure means being adapted to yield to permit said jaws to open in response to contact with the latch member as it is moved in said first direction under the influence of said platform pivoting means, (i) actuator means on said jaws adapted to interact with one another whereby movement of one jaw toward the open position causes movement of the other jaw toward the open position.
Claim 3
Dependent Claim
113 words
A tail-gate assembly as claimed in claim 1 wherein first of said jaws has a first length extending from its pivot mounting to its associated tooth, said first length having a cam face disposed opposite the second of said jaws, said cam face being inclined forwardly from the first pivot mounting to the first jaw in a direction toward said second jaw, said second jaw having an arm projecting toward said first jaw and bearing against said cam face, said arm being moveable along said cam face in response to rotation of said second jaw toward its open position to move said first jaw to its open position thereby to open said jaws.
