Claim Text:
1. A slide positioning device for a sliding mechanism that includes an exterior plate, an intermediate plate connected slidably to the exterior plate and an interior plate connected slidably to the intermediate plate, each of the exterior, intermediate and interior plates further having an inner side surface and an outer side surface, the slide positioning device comprising: a stop block formed on the inner side surface of the exterior plate; a through hole formed through the inner and outer side surfaces, of the intermediate plate; a pivot element mounted pivotally on the inner side surface of the intermediate plate adjacent to said through hole and that has opposite front and rear ends, the rear end being formed with a projection extending through said through hole so that in an engaged state, the projection is engaged with one side of said stop block on said exterior plate due to a force of gravity upon the projection so that the front and rear ends in the horizontal direction are balanced, thereby preventing sliding action between the exterior plate and the intermediate plate; and a resilient element mounted securely on the inner side surface of the intermediate plate and that has a free end in contact with the front end of said pivot element; and a push element that is fixed on the outer side surface of the interior plate and that is formed with a cam face; wherein when a force is applied to cause a sliding action between the interior plate and the intermediate plate, the push element pushes the resilient element to enable the resilient element to be rotated to apply a force to the pivot element so that the projection is detached from said stop block to permit slide action between the exterior plate and the intermediate plate.
