Abstract

A hard top removal assist system for a vehicle. The system includes a vehicle body having a plurality of rails mounted to the vehicle body. A hard top has a connection that is used to connect the hard top to the plurality of rails. There is at least one connection on the hard top that is slidable in the one or more rails between an installed position and a removed position. The hard top can be fully removed from the vehicle body and the one or more rails.

First claim

What is claimed is:

1. A hard top removal assist system for a vehicle comprising:
a vehicle body having a plurality of rails mounted to the vehicle body;
a hard top having at least one connection with each of the plurality of rails mounted to the vehicle body, wherein a first end of the plurality of rails is spaced away at a space distance from a rear side of the vehicle and a second end of the plurality of rails is opposite the first end and is closer to the rear side of the vehicle and the second end of the plurality of rails has an open end that connects to a channel that terminates at a closed end and the at least one connection slides into the channel at the open end of one of the plurality of rails, wherein the at least one connection is slidable in the plurality of rails between an installed position, and a removed position where the hard top can be fully removed from the vehicle body and the plurality of rails;
wherein the closed end of the channel has a lock mechanism that releasably grasps the at least one connection to hold the hard top in place at an installed position, wherein the lock mechanism has fingers that grasp a neck to hold the hard top in place at the installed position and the lock mechanism releases the at least one connection when the hard top is moved to the removed position and the at least one connection includes a dog post having the neck that connects to the hard top and a foot that is positioned in the channel, and
wherein each of the plurality of rails has a wide aperture portion that connects to a narrow aperture portion, wherein when the foot of the dog post is positioned in the channel, the neck extends through one of the wide aperture portion and the narrow aperture portion depending on whether the dog post is positioned in the portion of the channel where the wide aperture portion is located or where the narrow aperture portion is located, and
an actuator having an arm connectable to the dog post for moving the dog post and the hard top between the installed position and the removed position.

2. The hard top removal assist system for a vehicle of claim 1 wherein the plurality of rails extend parallel to a longitudinal axis of the vehicle.

3. The hard top removal assist system for a vehicle of claim 1 further comprising a cart having bow arms shaped to receive and support the hard top as the hard top moves past a rear side of the vehicle to a removed position.

4. The hard top removal assist system of claim 1 wherein the actuator includes:
a motor;
a gear train connected to the motor, wherein the motor is capable to rotating the gear train bidirectionally;
a threaded rod connected to and rotatable with the gear train;
a cylinder connected to the threads of the threaded rod, wherein the threads of the threaded rod extend inside of the cylinder so that when the threaded rod rotates in a first direction the cylinder moves so that the threads move off of the cylinder and when the threaded rod rotates in second direction the threads move into the cylinder; and
wherein the arm extends from the cylinder.

5. The hard top removal assist system of claim 1 wherein the actuator includes:
a threaded rod having threads on the outer surface, the threaded rod being connected between a stationary mount and a motor capable of rotating the threaded rod bidirectionally;
a shuttle connectable to the threads of the threaded rod, wherein the shuttle is movable along the length of the threaded rod and when the threaded rod rotates in a first direction the shuttle moves in a first direction, and when the threaded rod rotates in a second direction the shuttle moves in a second direction;
wherein the arm is connected to the shuttle and pushes or pulls the dog post causing the hard top to move between the installed position or removed position.

6. The hard top removal assist system of claim 1 wherein the actuator includes:
a motor, that rotates a gear bidirectionally;
a belt connected between the gear and a roller, wherein one surface of the belt has teeth that mate with teeth formed on the gear, wherein the teeth of the belt provide traction for rotating the belt;
a shuttle connected to and moveable with the belt, wherein the arm is connected to the shuttle and the arm contacts and pushes or pulls the dog post causing the hard top to move between the installed position or removed position.

7. The hard top removal assist system of claim 1 wherein further comprising the actuator connectable to the at least one connection for moving the hard top and the at least one connection between the installed position and the removed position.

8. A hard top removal assist system for a vehicle comprising:
a vehicle body having a plurality of rails mounted to the vehicle body;
a hard top having at least one connection with each of the plurality of rails mounted to the vehicle body, wherein a first end of the plurality of rails is spaced away at a space distance from a rear side of the vehicle and a second end of the plurality of rails is opposite the first and closer to the rear side of the vehicle and the second end of the plurality of rails has an open end that connect to a channel that terminates at a closed end and the at least one connection slides into the channel at the open end of one of the plurality of rails, wherein the at least one connection is slidable in the plurality of rails between an installed position, and a removed position where the hard top can be fully removed from the vehicle body and the plurality of rails;
wherein the closed end of the channel has a lock mechanism that releasably grasps the at least one connection to hold the hard top in place at an installed position, wherein the lock mechanism has fingers that grasp a neck to hold the hard top in place at the installed position and the lock mechanism releases the at least one connection when the hard top is moved to the removed position and the at least one connection includes a dog post having the neck that connects to the hard top and a foot that is positioned in the channel;
wherein each of the plurality of rails has a wide aperture portion that connects to a narrow aperture portion, wherein when the foot of the dog post is positioned in the channel, the neck extends through one of the wide aperture portion and the narrow aperture portion depending on whether the dog post is positioned in the portion of the channel where the wide aperture portion is located or where the narrow aperture portion is located;
an actuator having an arm connectable to the dog post for moving the dog post and the hard top between the installed position and the removed position, and
a cart having bow arms shaped to receive and support the hard top as the hard top moves past a rear side of the vehicle to a removed position.

9. The hard top removal assist system for a vehicle of claim 8 wherein the plurality of rails extend parallel to a longitudinal axis of the vehicle.

10. The hard top removal assist system of claim 8 wherein the actuator includes:
a motor;
a gear train connected to the motor, wherein the motor is capable to rotating the gear train bidirectionally;
a threaded rod connected to and rotatable with the gear train;
a cylinder connected to the threads of the threaded rod, wherein the threads of the threaded rod extend inside of the cylinder so that when the threaded rod rotates in a first direction the cylinder moves so that the threads move off of the cylinder and when the threaded rod rotates in second direction the threads move into the cylinder; and
wherein the arm extends from the cylinder.

11. The hard top removal assist system of claim 8 wherein the actuator includes:
a threaded rod having thr
