Abstract: A boat trailer extender that comprises of a track bar that connects to a tow vehicle, a guide bar that mounts on the track bar, the guide bar is configured to receive a boat trailer, four horizonal and four vertical guide bar rollers that are used to stabilize the guide bar on the track bar, a winch that is used to move the guide bar, the winch uses a strap and a series of track guide rollers that form a strap loop, and a closed loop strap brake that is used to add tension to the strap as it is spooled onto a spool of the winch. The spool is a two-sided spool, a first side of the spool can release and retrieve the strap as the guide bar is moved on the track bar, and a second side of the spool can retrieve and release the strap as the guide bar is moved on the track bar.

Abstract: This invention is related to a Passengers' Transportation System and refers to a system of two mechanisms that allows the transportation of passengers without stopping to drop or incorporate them. They are: a Covered Linear Transporting Floor mechanism and a Uniformly Varied Movement Mechanism. This system includes a covered linear transporting floor that moves at a constant speed which is equivalent to the average speed of vehicles in a city. The Covered Linear Transporting Floor Mechanism connects different points on a given route while the other one with the Uniformly Varied Movement Mechanism allows passengers get on and off of the Covered Linear Transporting Floor Mechanism by themselves. The gradual change in speed is achieved by having the floor of the Uniformly Varied Movement Mechanism, made of sliding steps that slide one on top of the other, at different speed ranges, guided by a set of rails and speed variation systems that could be mechanical, electro-mechanic or electromagnetic.
