Abstract
Disclosed is a roof safety latch for use with travel trailers of the type having a top which is lifted and lowered to expand and contract the trailer between living quarters and road travel conditions, respectively. The travel trailer disclosed includes four telescoping upright posts at the corners of the trailer. The posts are extended to lift the trailer roof by operating a winch to haul in a main cable coupled to a yoke and from which yoke individual cables extend to each post. The safety latch hereof includes a rod carried by the yoke and which rod has a catch at its distal end which rides in a guideway. A keeper including an opening defined in the guideway is located such that the catch engates the keeper when the yoke has been hauled in sufficiently to fully extend the posts and raise the top. The rod is springbiased such that the catch engages the keeper as the catch traverses the guideway. A release bracket is pivotally carried by the guideway to displace the catch from engagement with the keeper when it is desired to lower the trailer top.
