Abstract
A pickup truck tailgate lifting system and apparatus. The system in communication with the tailgate of the truck and located within an interior of the truck bed. The apparatus comprising a motor, a sprocket, a chain, and pins located on opposed ends of the tailgate, wherein the chain engages the tailgate and moves the tailgate from a closed position to an open position. The pins of the apparatus allow for normal operation of the tailgate during non-use of the apparatus.
Description
FIELD OF THE INVENTION

The invention relates generally to a pickup truck tailgate lifting system and apparatus.


BACKGROUND

Currently there are a number of solutions for loading and unloading a pickup truck. Some of these solutions attempt to unload in the traditional manner by lowering the tailgate and reaching in, but these solutions fail to meet the needs of the market because the suspension which makes a truck ride higher in the back makes accessibility into the truck beds is difficult. Other solutions attempt to have a person jump into the truck bed and unload that way, but these solutions are similarly unable to meet the needs of the market because this doesn't work for older people or people with disabilities.


SUMMARY OF THE INVENTION

It would be advantageous to have an apparatus that lifts the tailgate of a truck out of the way for access to cargo. Furthermore, it would also be advantageous to have an apparatus that is an electric motor with a chain/sprocket system that pulls and pushes the tailgate into the up position then back to the down position. Still further, it would be advantageous to have an apparatus connects to the top pins of the truck that the tailgate is latched to. Therefore, there currently exists a need in the market for an apparatus that is in communication with the various connection points and latches of a tailgate through engagement with a movable chain coupled the motor and engaged with a sprocket.


The motor and sprocket are positioned approximately half way between the vehicle cab and bed opening on opposed sides of an upper portion bed. The chain of the device traveling within a channel, the channel sized and configured to receive a pair of pins on each side of the tailgate. These four (4) pins traveling within the channel as the chain, sprocket, and motor pulls the tailgate into an upward position and push the tailgate into a downward position.


The invention advantageously fills the aforementioned deficiencies by providing a pickup truck tailgate lifting system and apparatus, which provides easier access to cargo in the bed of a pickup truck.


The invention is an electric motor with a chain/sprocket system that pulls and pushes the tailgate into the up position then back and into the down position. When not it in use, the device allows the four major pins of the truck/tailgate system to be in there original and normal positions allowing the tailgate to function normally when not using the lift system.


The apparatus has a motorized pulley system to pull the tailgate upwards and flat between the bed rails of the truck.


The apparatus allows for a quick release of the tailgate pins.


The apparatus fulfills the need for easier access to cargo in the back of a pickup truck.


Among other things, it is an advantage of the invention to provide a pickup truck tailgate lifting system and apparatus that does not suffer from any of the problems or deficiencies associated with prior solutions.


It is still further an advantage of the invention to be activated remotely or by a mounted switch.


Still further, the apparatus can be equipped with a pressure switch or electric eye to prevent property damage.


The invention now will be described more fully hereinafter with reference to the accompanying drawings, which are intended to be read in conjunction with both this summary, the detailed description and any preferred and/or particular embodiments specifically discussed or otherwise disclosed.

The invention is directed to be a pickup truck tailgate lifting system and apparatus.


Referring to the figures, FIG. 1-6 show the tailgate lifting system of the present invention, generally referred to as device 10. The device 10 is designed for placement within the interior portion of a truck bed 1 along the upper portion of the bed rails 2. Preferably, the device 10 is adaptable for aftermarket installation or capable as an add-on feature within new vehicles. The device 10 generally comprises a channel portion 100, a motor portion 200, a sprocket 201 coupled to the motor portion 200, and a chain 300 in communication with the sprocket 201 and in communication with a tailgate 11 of the vehicle. This composition is provided in duplicate with the configuration provided on each side of the truck bed 1 interior and in communication with each of the sides of the tailgate 11. The tailgate 11 including pins 111-114 located on its upper and lower sides for engagement with both the truck body and the track portion, wherein the pins 111-114 are received within the channel 100 and engaged to the chain 300 for movement of the tailgate 11 into an open position and a closed position.


When the apparatus 10 is not in use, the tailgate 11 functions normally and hingedly with the lower pins 112, 114 received within the body and frame of the truck bed 1. The pins 111-114 are in communication with the apparatus 10 wherein operation of the motors 200 disengages the pins 111-114 allowing for movement of the tailgate 11 along the channel 100.


The motor 200 is provided in duplicate and mounted within the interior side of a truck bed 1 near the upper portion of the truck bed adjacent to the bed rails. The motors 200 are preferably electric an in coupled communication for simultaneous operation. The motor 200 may include mounting tabs 202 to aid in mounting the motor 200 within the bed 1. The motor 200 may also be provided as a feature within a new or existing vehicle and installed internally.


The motor 200 includes a sprocket 201 having geared teeth in communication with the chain 300. The chain 300 moving along the sprocket 201 during operation of the device 10. The chain 300 having an end opposite the sprocket 201. The end coupled to the tailgate 11 upper pins 111, 113, wherein movement of the motor 200 turns the sprocket 201, moves the chain 300 and opens or closes the tailgate 11. The tailgate 11 is pulled to an open position that spans the truck bed underneath the truck bed rails.


The tailgate 11 of the attached system travels within the channel 100 affixed to the interior of the truck bed 1. The pins 111-114 of the tailgate will engage within this channel 100 during movement of the motors 200 and sprockets 201. Accordingly, the tailgate 11 is capable of normal operation or powered operation via the device 10. The motor 200 can be installed as after market accessory and operated via remote or a switch mounted to the truck bed 1.


While the invention has been described above in terms of specific embodiments, it is to be understood that the invention is not limited to these disclosed embodiments. Upon reading the teachings of this disclosure many modifications and other embodiments of the invention will come to mind of those skilled in the art to which this invention pertains, and which are intended to be and are covered by both this disclosure and the appended claims. It is indeed intended that the scope of the invention should be determined by proper interpretation and construction of the appended claims and their legal equivalents, as understood by those of skill in the art relying upon the disclosure in this specification and the attached drawings.
