Abstract
The present combination ladder rack and loader device is designed for use with pickup trucks. This device can function as a typical ladder rack, but also has the ability to lift large and heavy objects both into and out of the truck's bed. In one embodiment, the combination ladder rack and loader device can connect to the pick-up truck primarily through a receiver hitch allowing it to be easily disconnected from the truck when desired. This device can also comprise either a mechanical or an electrical winch to assist in the loading and unloading of large or heavy objects.
Claims20
A combination rack and loader device comprising:
- a boom section comprising a first horizontal support member and a second horizontal support member, wherein at least one cross member is connected perpendicularly to both the first horizontal support member and the second horizontal support member, and at least one side rack support vertically extending from the first horizontal support member when the first horizontal support is resting in the horizontal position to function as a ladder rack;
- a first boom rest configured to receive the first horizontal support member and a second boom rest configured to receive the second horizontal support member;
- a first vertical support member connected perpendicularly to the first horizontal support member, and a second vertical support member connected perpendicularly to the second horizontal support member, wherein when the first horizontal support member and the second horizontal support member are in a horizontal position when supported by the first boom rest and the second boom rest;
- an attachment base adapted to be removably connected to a tow hitch receiver, the attachment base comprising a bumper having a first end and a second end, the first end connected to a first main pivot bracket, and the second end connected to a second main pivot bracket, wherein the first vertical support member is pivotably connected to the first main pivot bracket and the second vertical support member is pivotably connected to the second main pivot bracket;
- a first actuator configured to pivot the first vertical support member about the first main pivot bracket, wherein the first actuator is configured to rotate the first main pivot bracket more than ninety degrees;
- and
- a control unit to control the first actuator.

A method for loading and unloading objects into a pickup truck's bed, the method comprising:
- providing a pickup truck connected to a combination rack and loader device comprising:
- a boom section comprising a first horizontal support member and a second horizontal support member, wherein at least one cross member is connected perpendicularly to both the first horizontal support member and the second horizontal support member, and at least one side rack support vertically extending from the first horizontal support member when the first horizontal support is resting in the horizontal position to function as a ladder rack;
- a first boom rest configured to receive the first horizontal support member and a second boom rest configured to receive the second horizontal support member;
- a first vertical support member connected perpendicularly to the first horizontal support member, and a second vertical support member connected perpendicularly to the second horizontal support member, wherein when the first horizontal support member and the second horizontal support member are in a horizontal position when supported by the first boom rest and the second boom rest;
- a winch connected to the cross member, and wherein the cross member is not located at an end of the first or second horizontal support members;
- an attachment base adapted to be removably connected to a tow hitch receiver, the attachment base comprising a bumper having a first end and a second end, the first end connected to a first main pivot bracket, and the second end connected to a second main pivot bracket, wherein the first vertical support member is pivotably connected to the first main pivot bracket and the second vertical support member is pivotably connected to the second main pivot bracket;
- a first actuator configured to pivot the first vertical support member about the first main pivot bracket and a second actuator configured to pivot the second vertical support member about the second main pivot bracket, wherein the first actuator is configured to rotate the first main pivot bracket more than ninety degrees and the second actuator is configured to rotate that second main pivot bracket more than ninety degrees;
- and
- a control unit to control the first actuator and the second actuator;
- and
- placing a back of the pickup truck bed near an object to be loaded;
- using the control unit to operate the first actuator and the second actuator thus moving the first vertical support member and second vertical support member backward until the combination rack and loader device into a fully back position relative to the pickup truck's bed;
- connecting the object to the winch using the cable and lifting the object to a height greater than the height of the pickup truck bed;
- using the control unit to operate the first actuator and the second actuator thus moving the first vertical support member and second vertical support member forward until the combination rack and loader device is in a fully down position relative to the pickup truck's bed, wherein the first boom rest receives the first horizontal support member and the second boom rest receives the second horizontal support member;
- using the winch to lower the object into the pickup truck bed;
- and
- reversing these steps to unload the object from the pickup truck's bed.
