Abstract: A trailer is configured with a slide mechanism operable to slidably couple a tie-down assembly with the trailer. The trailer includes a trailer frame configured with an axle and a pair of wheels for transporting a load over a distance. The slide mechanism includes an elongated member having a slot extending an axial length of the elongated member. The slide mechanism further includes a channel disposed parallel to and in communication with the slot. The channel has a width that exceeds the gap width of the slot. The slide mechanism further includes a carriage bolt and a tightening nut. The channel is configured to maintain the head of the carriage bolt adjacent to the slot. The carriage bolt and tightening nut slidably couple the tie-down assembly to the trailer frame.

Abstract: A latch assembly is provided for selectively maintaining a ramp of a trailer in a storage position. The latch assembly includes a mounting tube mounted to the underside of the trailer and a clamp tube operatively connected to the mounting tube by a plurality of link arms. The clamp tube is vertically movable between an interfering position wherein the clamp tube is vertically spaced from the mounting tube and interfering portions of the link arm intersect the plane in which the ramp of the trailer lies and a non-interfering position where the clamp tube is adjacent the mounting tube.

Abstract: A trailer is provided for accommodating various sized watercraft thereon. The trailer includes a frame structure extending along the longitudinal axis and a wheel and axle assembly for supporting the frame structure above a supporting surface. First and second bunk elements are supported by the frame structure. The first bunk element is movable along an axis transverse to the longitudinal axis to vary the distance between the bunk elements and is also movable along an axis parallel to the longitudinal axis of the frame structure between a forward position and a rearward position.

Abstract: A support structure is provided for supporting a canopy on a trailer. The support structure includes a first support arm having a first end pivotably connected to the canopy and a second pivotably connected to the first end of an intermediate support arm. The second end of the intermediate support arm is pivotably connected to the first end of a third support arm. The second end of the third support arm is pivotably connected to the trailer. First and second pneumatic springs are also provided. First pneumatic spring interconnects the first support arm and intermediate arm and the second pneumatic spring interconnects the intermediate support arm and the third support arm. The pneumatic springs assist an operator in lifting the canopy and provides sufficient force to maintain the canopy in an open position.

Abstract: A trailer is provided which accommodates a plurality of various sized watercraft thereon. The trailer includes a bow stop assembly slidably mounted to the frame structure of the trailer. Similarly, bunk elements are provided which are slidably mounted to the frame structure so as to allow the bunk elements to slide transverse to the longitudinal axis of the trailer.

Abstract: A winch construction for a boat lift. The winch includes a pair of spaced side plates, and a shaft is journaled in aligned openings in the side plates. The ends of the shaft project beyond the side plates and a drum is located between the side plates and is journaled on the shaft. A chain drive connects one projecting end of the shaft to a second shaft which is journaled in the side plates, and a second speed reduction chain drive connects the second shaft with the drum which carries a cable which is attached to the boat lift. A hand wheel is connected to a hub that is threaded on the opposite projecting end of the shaft, and an annular ratchet is located between the hub and a backing plate attached to the respective side plate. The ratchet is composed of a brake material and has a brake surface facing the backing plate. To elevate the boat lift, the hand wheel is rotated causing the hub to move axially on the shaft and effecting engagement of the brake surface with the backing plate.
