Abstract
A boat trailer modified to include a dolly and dolly track, the dolly including a hook triggering mechanism, a bow cradle and a slidable hooking mechanism for engaging a watercraft bow ring at a wide range misalignment with the centerline of the trailer. The trailer further including a remote controlled power winch with an automatic shut off for stopping the power winch when a watercraft is fully loaded. The invention enabling a single user to launch a securely retrieve a watercraft to and from a watercraft trailer.
Claims8

- c. a first support bar fixedly attached proximate said first ends of said first and second dolly frame rails;
- d. a constant force cable tensioner attached to said first support bar, the cable of said constant force cable tensioner being attached at first end to said cable tensioner and at a second end to said track strut;
- e. a second support bar fixedly attached proximate the longitudinal center of said dolly frame rails;
- f. a first and second cradle frame rails pivotably mounted at a first end to said second support bar, one cradle frame rail mounted proximate each end of said second support bar;
- g. a third and fourth support bars fixedly mounted to said first and second cradle frame rails;
- h. a first and second air shocks mounted at a first end proximate the second end of said cradle frame rails and at a second end to the front end support bar, said front end support bar fixedly attached to a second end of said dolly frame rails;
- i. a fifth support bar fixedly mounted to said dolly frame rails between said second support bar and said front end support bar;
- j. a spring biased triggering mechanism for activating and deactivating a hooking mechanism;
- and
- k. a bow cradle assembly pivotably mounted to said second ends of said cradle frame rails, said cradle frame assembly comprising:
- 1. two bow cradle assembly rails connected by two cross member supports;
- 2. two bow protector and alignment guides attached to said bow cradle assembly rails;
- 3. a bow stop adjustably mounted to said bow cradle assembly rails;
- 4. two hook mechanism support bars pivotably mounted to said bow cradle assembly rails;
- 5. a hook mechanism slide bar fixedly attached to said hook mechanism support bars;
- and
- 6. a hook mechanism slidable attached to said hook mechanism slide bar, said hook mechanism comprising:
- a. a hook frame;
- b. four rotatable rollers which ride on said hook mechanism slide bar;
- c. a first spring which is attached at a first end to said hook frame and at a second end to said hook mechanism support bars;
- d. a second spring which is attached at a first end to the second end of said triggering mechanism cable and at a second end to said hook frame;
- e. a hook plate is fixedly attached to said hook frame, said hook plate having an angled through-hole slot;
- f. a first pivot pin rotatably and slideably mounted in said slot;
- g. attached to said first pivot pin on a first end is a watercraft hook and on a second end is a rotatable first end of a first linkage bar;
- h. attached to the second end of said first linkage bar is a first end of a second linkage bar;
- i. the second end of said second linkage bar is rotatably attached to a first end of a second pivot pin;
- j. a hook rest is attached to the second end of said second pivot pin;
- k. a third spring is attached at a first end to said second end of said first linkage bar and at a second end to said hook frame;
- and
- l. a fourth spring is wrapped around said hook rest and attached at both ends to said hook.
A watercraft trailer, comprising:
- a watercraft support having a front end, a rear end and a plurality of trailer wheels disposed proximate said rear end;
- a trailer hitch disposed on the front end of said watercraft support for releasably securing said trailer to a tow vehicle;
- a post arm fixedly attached proximate said front end of said watercraft support, said post arm having a remotely controlled power winch, a power winch cutoff switch and watercraft bow support rollers attached thereto;
- a key chain remote to operate said winch;
- first and second dolly track rails disposed linearly along said watercraft support;
- a rear track strut fixedly attached to the rear end of said first and second dolly track rails;
- a position lever rail fixedly attached to the top of said first dolly track rail, said position lever rail having first and second cutouts;
- and
- a dolly assembly movably disposed along said dolly track rails, said dolly assembly being spring biased in a rearward direction and having a pivotably bow cradle assembly mounted to the top of said dolly assembly and a spring biased triggering mechanism in contact with said position lever rail, said bow cradle assembly having bow protectors and a spring biased hooking mechanism pivotally and slideably attached to said bow cradle assembly, and said spring biased hooking mechanism have a spring biased bow hook rotatably and slidable attached to said hooking mechanism with a spring biased cable attached to said hooking mechanism at a first end and at a second end to said triggering mechanism.
A means for a single user to remotely launching a watercraft from a watercraft trailer, comprising:
- having a user back said trailer with said watercraft removable attached to a bow cradle assembly by a hook and power winch means down a watercraft ramp and into a body of water with the use of a tow vehicle, said bow cradle assembly being pivotally attached to a movable dolly means;
- having a user exit said tow vehicle and enter said watercraft;
- having said user operate a remote control means for activating said power winch means which releases said power winch means;
- having a tension means attached at a first end to said trailer and at a second end to said dolly for pulling said movable dolly, said bow cradle assembly and attached watercraft proximate the rear of said trailer;
- and
- having a triggering means that automatically releases said hook from said watercraft once said dolly, said bow cradle and said watercraft are proximate the rear of said trailer, thereby launching said watercraft.
A means for a single user to remotely retrieving a motor powered watercraft to a watercraft trailer, comprising:
- powering said watercraft onto a bow cradle assembly, said bow cradle assembly being pivotally mounted to a moveable dolly, said dolly being movably mounted to said trailer, said trailer being partially submerged in water on a trailer ramp;
- driving said watercraft, said bow cradle and said movable dolly forward on said trailer until a triggering means mounted on said dolly is triggered, said triggering means causing a pivotal and slideable hooking means to move into a position and engage said hook with a bow ring on said watercraft;
- activating a remote control means, said remote control means activating a power winch means attached to said hooking means which pulls said watercraft into alignment with said trailer and into a fully retrieved position on said trailer, said power winch means being turned off when a bow stop means contacts a power winch shutoff means.
