Rope adjuster with fast rope replacement device

1. A rope adjuster device for allowing adjustable positioning of a load along a rope extending through the device and providing convenient replacement of the rope, the rope adjuster device comprising:

a rope bite having a first state wherein a rope extending through the device is gripped to prevent translation of the device along the length of the rope and a second state wherein the device may translate along the length of the rope; the rope bite defined by a rope guide surface and a bite cam that is movable relative to the rope guide surface between a gripping position wherein the rope is gripped between the bite cam and the rope guide surface in the first state and a release position wherein the rope may translate through the bite along the length of the rope in the second state, the rope bite being open on a lateral side to allow loading of the rope into the bite by moving the rope laterally with respect to the length of the rope;

a cam carrier defining the rope guide surface, the bite cam mounted on the carry carrier for movement between the gripping and release positions;

a frame defining a connector opening, the frame extending from the connector opening to a pivot location whereat the cam carrier is connected to the frame to pivot relative to the frame between an open position wherein the rope can be loaded from the lateral side into the rope bite and a closed position wherein the lateral side is closed by the frame to prevent removal of the rope from the rope bite; and

wherein the bite cam is spring biased to pivot toward the gripping position.

2. The device of claim 1 wherein the cam carrier comprises a rigid lever member extending from the bite cam to the pivot location, the lever member operable by a user to place the rope bite in the second state by pivoting the cam carrier relative to the bite cam to move the rope guide surface away from the bite cam with the rope extending through the device and under load.

3. The device of claim 1 wherein the frame comprises a one-piece, rigid member extending from the connector opening to the pivot location.

4. The device of claim 3 wherein the rigid member extends over the lateral side of the rope bite with the cam carrier in the closed position.

5. A rope adjuster device for allowing adjustable positioning of a load along a rope extending through the device and providing convenient replacement of the rope, the rope adjuster device comprising:

a rope bite having a first state wherein a rope extending through the device is gripped to prevent translation of the device along the length of the rope and a second state wherein the device may translate along the length of the rope; the rope bite defined by a rope guide surface and a bite cam that is movable relative to the rope guide surface between a gripping position wherein the rope is gripped between the bite cam and the rope guide surface in the first state and a release position wherein the rope may translate through the bite along the length of the rope in the second state, the rope bite being open on a lateral side to allow loading of the rope into the bite by moving the rope laterally with respect to the length of the rope;

a cam carrier defining the rope guide surface, the bite cam mounted on the cam carrier for movement between the gripping and release positions;

a frame defining a connector opening, the frame extending from the connector opening to a pivot location whereat the cam carrier is connected to the frame to pivot relative to the frame between an open position wherein the rope can be loaded from the lateral side into the rope bite and a closed position wherein, the lateral side is closed by the frame to prevent removal of the rope from the rope bite, the cam carrier being spaced from the connector opening with the cam carrier in the closed position;

wherein the frame comprises a one-piece, rigid member extending from the connector opening to the pivot location;

wherein the rigid member extends over the lateral side of the rope bite with the cam carrier in the closed position; and

wherein the frame comprises another rigid member extending from the connector opening to the pivot location, the rigid members extending over opposite lateral sides of the cam carrier with the cam carrier in the closed position.

6. The device of claim 5 wherein the cam carrier comprises a protrusion extending outwardly beyond the rigid members with the cam carrier in the closed position, the protrusion engageable by a user to move the carrier from the dosed position toward the open position.

7. The device of claim 5 wherein the rigid members define rope conforming surfaces adjacent the connector opening to guide the rope past the frame when the cam carrier is moved from the open position to the closed position with the rope loaded into the bite cam.

8. The device of claim 5 wherein the rigid members are fixed to each other at the connector opening.

9. The device of claim 8 further comprising a grommet defining the connector opening and fixing the rigid members to each other.

10. A rope adjuster device for allowing adjustable positioning of a load along a rope extending through the device and providing convenient replacement of the rope, the rope adjuster device comprising:

a rope bite having a first state wherein a rope extending through the device is gripped to prevent translation of the device along the length of the rope and a second state wherein the device may translate along the length of the rope; the rope bite defined by a rope guide surface and a bite cam that is movable relative to the rope guide surface between a gripping position wherein the rope is gripped between the bite cam and the rope guide surface in the first state and a release position wherein the rope may translate through the bite along the length of the rope in the second state, the rope bite being open on a lateral side to allow loading of the rope into the bite by moving the rope laterally with respect to the length of the rope;

a cam carrier defining the rope guide surface, the bite cam mounted on the cam carrier for movement between the gripping and release positions;

a frame defining a connector opening, the frame extending from the connector opening to a pivot location whereat the cam carrier is connected to the frame to pivot relative to the frame between an open position wherein the rope can be loaded from the lateral side into the rope bite and a closed position wherein the lateral side is closed by the frame to prevent removal of the rope from the rope bite; and

wherein the cam carrier is spring biased to the closed position.

11. A rope adjuster device for allowing adjustable positioning of a load along a rope extending through the device and providing convenient replacement of the rope, the rope adjuster device comprising:

a rope bite having a first state wherein a rope extending through the device is gripped to prevent translation of the device along the length of the rope and a second state wherein the device may translate along the length of the rope; the rope bite defined by a rope guide surface and a bite cam that, is movable relative to the rope guide surface between a gripping position wherein the rope is gripped between the bite cam and the rope guide surface in the first state and a release position wherein the rope may translate through the bite along the length of the rope in the second state, the rope bite being open on a lateral side to allow loading of the rope into the bite by moving the rope laterally with respect to the length of the rope;

a cam carrier defining the rope guide surface, the bite cam mounted on the cam carrier for movement between the gripping and release positions;

a frame defining a connector opening, the frame extending from the connector opening to a pivot location whereat the cam carrier is connected to the frame to pivot relative to the frame between an open position wherein the rope can be loaded from the lateral side into the rope bite and a closed position wherein the lateral side is closed by the frame to prevent removal of the rope from the rope bite; and

further comprising a spring extending between the frame and the cam carrier at the pivot location to bias the cam carrier to the closed position.

12. The device of claim 1 wherein the connector opening is spaced further from the pivot location than the bite cam.
