Tonneau cover latch system
A latch system for a tonneau cover. The latch system includes a handle that is configured to move about an axis; and a latch pin connected to the handle. The latch pin is configured to move in a retracted direction and during movement of the handle towards the tonneau cover.
1. A latch system for a tonneau cover, the latch system comprising:
a handle that is configured to move;
a latch pin;
a bell crank in communication the latch pin; and
a cam follower that engages the handle and the bell crank;
wherein the bell crank moves when the cam follower is moved, which occurs when the handle is moved; and
wherein the latch pin is configured to move in a retracted direction during movement of the handle in a direction generally towards the tonneau cover.
2. The latch system according to claim 1 , wherein movement of the latch pin in the retracted direction is movement of the latch pin in a direction away from a side wall of a cargo area of a vehicle.
3. The latch system according to claim 1 , wherein the latch pin is configured to move in an extended direction during movement of the handle in a direction generally away from the tonneau cover.
4. The latch system according to claim 1 , wherein the bell crank is configured to rotate about an axis during movement of the handle in the direction generally towards the tonneau cover.
5. A latch system for a tonneau cover, the tonneau cover having at least one panel, the latch system comprising:
a handle;
a latch pin; and
a mechanism that is configured to convert rotation of the handle into movement of the latch pin, the mechanism comprises a bell crank and a cam follower, the bell crank comprises a protrusion that engages the cam follower;
wherein rotation of the handle in a direction generally towards the panel causes the latch pin to move.
6. The latch system according to claim 5 , wherein the rotation of the handle causes the cam follower to rotate, which causes the bell crank to rotate.
7. The latch system according to claim 6 , wherein the bell crank rotates about an axis that is generally perpendicular to an axis that the handle is configured to rotate about.
8. The latch system according to claim 5 , wherein the latch system comprises a second latch pin, and the bell crank comprises a first arm and a second arm,
wherein rotation of the bell crank causes the latch pin and the second latch pin to move.
9. The latch system according to claim 5 , wherein the handle comprises a channel that the cam follower engages.
10. The latch system according to claim 9 , wherein the cam follower comprises a T-shaped member that engages the channel.
11. The latch system according to claim 5 , wherein the latch system comprises a link provided between the bell crank and the latch pin.
12. The latch system according to claim 5 , wherein the latch system comprises a biasing member,
wherein the rotation of the handle is configured to compress the biasing member while the latch pin is moved in a first direction, and uncompressing of the biasing member moves the latch pin in a second direction.
13. A method of opening the tonneau cover having the latch system of claim 1 , comprising:
rotating the handle in the direction generally towards the panel of the tonneau cover to move the latch pin in a direction away from a side wall of a cargo area of a vehicle.
14. A latch system for a tonneau cover, the tonneau cover having a panel, the latch system comprising:
a handle;
a latch pin; and
a mechanism that is configured to convert rotation of the handle into movement of the latch pin, the mechanism includes a bell crank that engages a cam follower,
wherein rotation of the handle towards the panel of the tonneau cover causes the cam follower to move, which causes the bell crank to rotate, which causes the latch pin to move.
15. The latch system according to claim 1 , wherein the latch pin is configured to move along an axis that is generally perpendicular to an axis that the handle is configured to pivot about.
16. The latch system according to claim 1 , wherein the latch assembly comprises one or more links between the latch pin and the bell crank.
17. The latch system according to claim 1 , wherein the latch assembly comprises a bracket that supports movement of the mechanism.
18. The latch system according to claim 5 , wherein the latch system comprises a biasing member,
wherein the rotation of the handle in the direction generally towards the tonneau cover is configured to compress the biasing member.
19. The latch system according to claim 14 , wherein the latch system comprises a biasing member,
wherein the rotation of the handle towards the panel is configured to compress the biasing member.
20. The latch system according to claim 14 , wherein the bell crank comprises a feature that engages a slot or recess on the cam follower.
