The truck locking device includes a flat substantially triangular shaped support member having a vertically extending surface and an inclined surface, a pair of locking arms pivoted adjacent the intersection of the vertical and inclined surface on opposite sides of the support member, a pair of latches on opposite sides of said support member for latching the locking arms in retracted position substantially parallel to the inclined surface of the support member, a spring for normally biasing the locking arms upwardly independent of each other into engagement with a standard ICC bar on the back of a truck and an activating arm pivoted on the support member for pivotal movement under the influence of the bar as it is moved over the locking device to operate the latch members and release the locking arms for engagement with the bar to lock the truck in position relative to a loading dock or the like. Cables are provided for retracting the locking arms upon completion of a loading or unloading operation to release the truck. Upon retraction of the locking arms the locking arms will automatically be latched in the lowered position by the latch members and upon departure of the truck the activating arm will pivot to its original position for a subsequent truck locking operation.
A truck locking device comprising support means adapted to be secured on a suitable support surface, horizontally extending pivot means secured to said support means, locking arm means having at least one projection thereon pivotally mounted on said pivot means, spring means normally biasing said locking arm means upwardly for engagement with a horizontally disposed bar secured to a truck, lach means for securing said locking arm means to said support means in a lower retracted position and activating arm means pivotally mounted on said support means in operative engagement with said latch means whereby upon engagement of said bar with said activating arm means said activating arm means will be pivoted to release said latch means thereby allowing said locking arm means to pivot upwardly into locking engagement with said bar to secure the truck in position relative to said support means.
