Abstract: A telescoping slide assembly includes a latch blade pivotably mounted on an intermediate slide member, a latching lip on a stationary slide member, and a cam on a load-carrying slide member. The latch blade engages the latching lip automatically to block movement of the intermediate slide member relative to the stationary slide member toward a fully retracted position. The cam on the stationary slide member engages and pivots the latch blade to a position disengaging the latching lip in response to movement of the load-carrying slide member relative to the intermediate and stationary slide members toward a fully retracted position so that the intermediate slide member is released from latching engagement with the stationary slide member and free to move toward its fully retracted position.

Abstract: The present invention relates to telescoping slide assemblies having interconnected slide members including a stationary slide member, a chassis slide member, and an intermediate slide member positioned therebetween, and particularly to mechanisms for governing movement of a chassis slide member in a telescoping slide assembly. More particularly, the invention relates to multiple telescoping slide assemblies coupled together in parallel spaced-apart relation by a fixture attached to their respective intermediate slide members.

Abstract: A bridge composed of individual sections is assembled by means of an assembling unit whose support elements comprise two lateral beams, preferably lattice girders. The assembling unit includes a main cross beam which is bolted to the end of one of two adjoining bridge sections and is connected to the end of the next adjoining bridge section by a hinge means having a substantially horizontal axis. Each end of the main cross beam is mounted on a substantially vertical supporting leg.
