Tonneau cover assembly and clamp with grasping tether
A tonneau cover system can include a cover sized and shaped to cover the truck cargo box and a spring clamp designed to secure the cover to the truck cargo box. The spring clamp can include a rod connected to the cover. The rod can have a rod axis. A clamp body can be rotatably and slidably mounted on the rod. The clamp body can include a pair of oppositely disposed catches spaced apart from the rod axis. The catches can extend in a catch length direction intersecting the rod axis at a first angle. A grasping tether can be attached to the clamp body for manually sliding the clamp body along the rod in a direction away from the cover. Due to the flexible nature of the grasping tether, potential interference of the clamp with cargo in the cargo box can be significantly reduced.

2. The tonneau cover assembly according to claim 1 , wherein the clamp is designed to secure the cover to the cargo box by engaging the catch against a distal edge of a downwardly extending inboard flange of a side wall of the truck cargo box.
3. The tonneau cover assembly according to claim 1 , wherein the catch extends along a catch axis perpendicular to the first direction.
4. The tonneau cover assembly according to claim 3 , wherein the tether comprises a strap having a greatest cross-sectional dimension, and wherein the direction of the greatest cross-sectional dimension extends parallel to the catch axis.
5. The tonneau cover assembly according to claim 3 , further comprising a first pin having a first pin axis and a second pin having a second pin axis, the first pin and the second pin each coupled to the clamp body and extending parallel to the catch axis, and wherein the tether comprises a strap having a first closed loop at a first end extending around the first pin to couple the first end of the strap to the clamp body and a second closed loop at a second end extending around the second pin to couple the second end of the strap to the clamp body.
6. The tonneau cover assembly according to claim 1 , wherein the clamp body is rotatably and slidably mounted on the rod, and wherein the catch is a first catch, and wherein the clamp body comprises a second catch spaced apart from the rod axis in a second direction generally opposite the first direction.
7. A tonneau cover assembly according to claim 1 , wherein the clamp further comprises a spring biasing the clamp body along the rod axis in a direction toward a proximal end of the rod adjacent the cover.
8. A tonneau cover assembly according to claim 1 , wherein the clamp body further comprises a surface grasping feature positioned to be located above a distal edge of a downwardly extending inboard flange of a side wall of the truck cargo box when the catch is clamped against the distal edge.
9. A tonneau cover assembly according to claim 1 , wherein the clamp body further comprises a surface grasping feature positioned to be located above the catch.
10. A tonneau cover assembly for a truck cargo box comprising a side wall, the tonneau cover assembly comprising:
a cover sized and shaped to cover the truck cargo box; and
a clamp designed to secure the cover to the side wall of the truck cargo box, the clamp comprising:
a rod having a first end pivotally connected to the cover and a distal end apart from the cover, the rod having a rod axis;
a clamp body rotatably and slidably mounted on the rod, the clamp body comprising a first catch spaced apart from the rod axis in a first direction and extending along a first catch axis, and a second catch spaced apart from the rod axis in a second direction generally opposite the first direction and extending along a second catch axis parallel to the first catch axis;
a spring biasing the clamp body along the rod axis in a direction toward the cover; and
a tether attached to the clamp body for sliding the clamp body along the rod in a direction away from the cover, the tether comprising a strap having a greatest cross-sectional dimension, wherein the direction of the greatest cross-sectional dimension extends parallel to the first catch axis and the second catch axis.
11. The tonneau cover assembly according to claim 10 , further comprising a first pin having a first pin axis and a second pin having a second pin axis, each pin being coupled to the clamp body with each pin axis extending parallel to the first catch axis and the second catch axis, and wherein the strap has a first closed loop at a first end extending around the first pin to couple the first end of the strap to the clamp body and a second closed loop at a second end extending around the second pin to couple the second end of the strap to the clamp body.
12. The tonneau cover assembly according to claim 11 , wherein the greatest cross-sectional dimension extends parallel to the first pin axis and to the second pin axis.
13. The tonneau cover assembly according to claim 10 , wherein the first pin axis is spaced from the rod axis in the first direction and the second pin axis is spaced from the rod axis in the second direction.
14. The tonneau cover assembly according to claim 10 , wherein the clamp is designed to secure the cover to the cargo box by engaging the catch against a distal edge of a downwardly extending inboard flange of a side wall of the truck cargo box.
15. A tonneau cover assembly according to claim 10 , wherein the clamp body further comprises a surface grasping feature positioned to be located above a distal edge of a downwardly extending inboard flange of a side wall of the truck cargo box when the catch is clamped against the distal edge.
16. A tonneau cover assembly according to claim 10 , wherein the clamp body further comprises a surface grasping feature positioned to be located above the catch.
