Tonneau cover hinge
View Patent ↗A hinge system is used to adjust a cover member between a closed position where the cover member covers at least a portion of a vehicle bed and an open position where the cover member does not cover the vehicle bed. The hinge system may include first and second arms that are pivotally attached and a biasing device operatively connected to the first and second arms that biases the cover member toward the open position whenever the cover member is not in the closed position and that does not bias the cover member toward the open position whenever the cover member is in the closed position.
1. A hinge system for use in adjusting a cover member between a closed position where the cover member covers at least a portion of a vehicle bed and an open position where the cover member does not cover the vehicle bed, the hinge system comprising:
a first arm having first and second ends and a midsection, the first end adapted to be connected to the vehicle and the second end adapted to be connected to the cover member;
a second arm having first and second ends and a midsection, the first end adapted to be connected to the vehicle and the second end adapted to be connected to the cover member, the midsection of the first arm being pivotally connected to the midsection of the second arm; and,
a biasing device, operatively connected to either the first arm or the second arms, that biases the cover member toward the open position whenever the cover member is not in the closed position and that does not bias the cover member toward the open position whenever the cover member is in the closed position.
2. The hinge system of claim 1 wherein the midsection of the first arm, the midsection of the second arm, and the biasing device are substantially parallel when the cover member is in the closed position.
3. The hinge system of claim 2 wherein the biasing device is a tension spring.
4. The hinge system of claim 2 wherein the first end of the first arm is slidingly connected to the vehicle.
5. The hinge system of claim 4 further comprising:
a slide bar assembly operatively connected to the first end of the first arm, the slide bar assembly comprising: (a) a slide bar that is slideable within a channel defined in a vehicle wall; and, (b) a bracket positioned between the slide bar and the first end of the first arm.
6. The hinge system of claim 5 wherein the bracket has a groove that permits the slide bar to be position adjusted with respect to the bracket.
7. A hinge system comprising:
a first arm having first and second ends and a midsection, the first end adapted to be connected to an associated vehicle;
a second arm having first and second ends and a midsection, the first end adapted to be connected to the vehicle, the midsection of the first arm being pivotally connected to the midsection of the second arm; and,
a mounting rail adapted to be connected to a cover member used to cover an associated vehicle's bed, the mounting rail having a channel that slidingly receives one of the second ends of the first and second arms and that pivotally receives the other of the second ends of the first and second arms.
8. The hinge system of claim 7 wherein one of the first ends of the first and second arms is adapted to be slidingly connected to the vehicle and the other of the first ends of the first and second arms is adapted to be pivotally connected to the vehicle.
9. The hinge system of claim 8 further comprising:
a biasing device positioned within the channel.
10. The hinge system of claim 9 wherein the first end of the first arm is slidingly connected to the vehicle and the second end of the first arm is slidingly connected to the mounting rail.
11. The hinge system of claim 10 wherein the biasing device is a tension spring.
12. The hinge system of claim 10 wherein the first end of the second arm is pivotally connected to an arm bracket that is received within the mounting rail channel.
13. The hinge system of claim 12 wherein the arm bracket is position adjustable within the channel.
14. The hinge system of claim 9 wherein the biasing device has a first end connected to a spring bracket that is received within the channel and a second end connected to a slide bar that is received within the channel.
15. A method comprising the steps of:
providing a vehicle having a vehicle bed;
providing a cover member;
providing a hinge system for use in adjusting the cover member with respect to the vehicle bed, the hinge comprising a biasing device;
positioning the cover member into a closed position where the cover member covers at least a portion of the vehicle bed and the biasing device does not bias the cover member;
beginning to adjust the cover member toward an open position thereby placing the biasing device into a condition where it biases the cover member toward the open position; and,
adjusting the cover member into the open position.
16. The method of claim 15 further comprising the steps of:
beginning to adjust the cover member toward the closed position thereby overcoming the biasing force of the biasing device; and,
positioning the cover member into the closed position thereby returning the biasing device to the condition where it does not bias the cover member.
17. The method of claim 16 wherein:
the step of providing a hinge system for use in adjusting the cover member with respect to the vehicle bed, the hinge comprising a biasing device, comprises the steps of: (1) providing a first arm having first and second ends and a midsection; (2) providing a second arm having first and second ends and a midsection; (3) pivotally connecting the midsection of the first arm to the midsection of the second arm; (4) attaching the first end of the first arm to the vehicle; (5) attaching the first end of the second arm to the vehicle; and, (6) positioning the biasing device between the second end of the first arm and the second end of the second arm; and,
the step of positioning the cover member into a closed position where the cover member covers at least a portion of the vehicle bed and the biasing device does not bias the cover member, comprises the step of: positioning the midsection of the first arm, the midsection of the second arm, and the biasing device into substantially parallel alignment.
18. The method of claim 17 wherein:
the step of providing a hinge system for use in adjusting the cover member with respect to the vehicle bed, the hinge comprising a biasing device, further comprises the steps of: providing a mounting rail having a channel; and, connecting the mounting rail to the cover member;
the step of beginning to adjust the cover member toward an open position thereby placing the biasing device into a condition where it biases the cover member toward the open position, comprises the steps of: sliding one of the second ends of the first and second arms along the channel; and, pivoting the other of the second ends of the first and second arms about the mounting rail.
