Abstract

A shuttle ( 20 ) for a climbing protection system ( 10 ) is provided and includes a clamping member ( 26 ) mounted on a frame ( 22 ) for movement between a an opening position, a free position wherein the shuttle ( 20 ) can move freely along an elongate support member ( 12 ), and a clamping position wherein the clamping member ( 26 ) resists movement of the shuttle ( 20 ) relative to the elongate support member ( 12 ), and an anti-inversion member ( 30 ) mounted on the frame ( 22 ) for movement between a first closed position blocking insertion of the elongate support member ( 12 ) and an open position where the anti-inversion member ( 30 ) does not block insertion of the elongate support member ( 12 ). The anti-inversion member movable from the open position to the closed position when the shuttle ( 20 ) is moved from a desired orientation to a non-desired orientation relative to gravity with the clamping member ( 26 ) in the opening position and wherein the clamping member ( 26 ) and the anti-inversion member ( 30 ) are engaged to maintain the clamping member ( 26 ) in the opening position when the shuttle ( 20 ) is in the non-desired orientation.

First claim

The invention claimed is:

1. A climbing protection system comprising:
a frame;
a guide structure on the frame and configured to receive a support member and to guide the climbing protection system along the support member in response to a user, attached to the climbing protection system, climbs a ladder or a platform;
a clamping member mounted on the frame configured to move between a free position and a clamping position, wherein the climbing protection system can move freely along the support member in the free position and wherein the clamping member engages the support member in the guide structure to resist movement of the climbing protection system relative to the support member in the clamping position;
an anti-inversion member mounted on the frame configured to move between a first closed position wherein the anti-inversion member blocks the support member from being received into the guide structure with the climbing protection system in an inverted position relative to gravity, and an open position wherein the anti-inversion member does not block the support member from being received in the guide structure; and
wherein:
the clamping member comprises a surface that engages a surface on the anti-inversion member to move the anti-inversion member between a second closed position wherein the anti-inversion member blocks the support member from being removed from the guide structure with the climbing protection system in a non-inverted position relative to gravity, and the open position as the clamping member moves between the free position and an opening position, wherein the clamping member in the opening position engages the anti-inversion member to maintain the anti-inversion member in the open position with the climbing protection system in the non-inverted position relative to gravity.

2. The climbing protection system of claim 1 wherein the anti-inversion member is mounted on the frame configured to pivot between the first closed position, the second closed position and the open position of the anti-inversion member.

3. The climbing protection system of claim 1 , wherein the anti-inversion member is configured to move between the open position and the second closed position.

4. The climbing protection system of claim 1 , wherein the anti-inversion member is configured to move to the first closed position under a force of gravity in response to the climbing protection system being placed in the inverted position relative to gravity after the clamping member has been moved to the opening position with the climbing protection system in the non-inverted position relative to gravity.

5. The climbing protection system of claim 1 wherein the anti-inversion member is configured to move from the open position to the second closed position by a force of gravity.

6. The climbing protection system of claim 1 wherein the clamping member and the anti-inversion member are configured to engage each other to maintain the clamping member in the opening position with the climbing protection system in the inverted position relative to gravity.

7. The climbing protection system of claim 1 wherein the clamping member and the anti-inversion member comprise interlocking features that are configured to engage each other to maintain the clamping member in the opening position with the climbing protection system in the inverted position relative to gravity.

8. The climbing protection system of claim 7 wherein the interlocking features comprise a finger formed on one of the clamping member and the anti-inversion member and a finger receiving notch formed on the other of the clamping member and the anti-inversion member.

9. The climbing protection system of claim 1 further comprising a blocking member mounted on the frame configured to move between a closed position blocking removal of the support member from the guide structure and an open position where the blocking member does not block removal of the support member from the guide structure.

10. The climbing protection system of claim 9 wherein the blocking member comprises:
a wheel configured to engage against the support member in the guide structure with the blocking member in the closed position; and
a carrier mounting the wheel for rotation, the carrier being pivot mounted to the frame.

11. The climbing protection system of claim 9 wherein the clamping member in the free position is configured to block removal of the support member from the guide structure, the clamping member in the opening position does not block removal of the support member, and the clamping member operably engages the blocking member to move the blocking member from the closed position to the open position as the clamping member is moved from the free position to the opening position.

12. The climbing protection system of claim 1 wherein the clamping member comprises:
a connection feature configured to receive a connector for attaching a user to the climbing protection system; and
a clamping surface that is configured to engage the support member received in the guide structure with the clamping member in the clamping position, the connection feature being spaced from the clamping surface.

13. The climbing protection system of claim 12 wherein the clamping member is pivot mounted to the frame at a location between the connection feature and the clamping surface.

14. A climbing protection system, comprising:
a frame;
a guide structure on the frame and configured to receive a support member and to guide the climbing protection system along the support member in response to a user, attached to the climbing protection system, climbs a ladder or a platform;
a clamping member mounted on the frame configured to move between a free position wherein the climbing protection system can move freely along the support member received in the guide structure and a clamping position wherein the clamping member engages the support member in the guide structure to resist movement of the climbing protection system relative to the support member, the clamping member configured to move from the free position to the clamping position in response to a downward movement by the user attached to the climbing protection system;
an anti-inversion member mounted on the frame configured to move between a first closed position wherein the anti-inversion member blocks the support member from being received into the guide structure with the climbing protection system in an inverted position relative to gravity, and an open position wherein the anti-inversion member does not block the support member from being received in the guide structure; and
wherein:
the clamping member and the anti-inversion member comprise interlocking features that engage each other to maintain the clamping member in an opening position with the climbing protection system in the inverted position relative to gravity, wherein the clamping member in the opening position engages the anti-inversion member to maintain the anti-inversion member in the open position with the climbing protection system in a non-inverted position relative to gravity.

15. A climbing protection comprising:
a frame;
a guide structure on the frame and configured to receive a support member and to guide the climbing protection system along the support member in response to a user, attached to the climbing protection system, climbs a ladder or a platform;
a clamping member mounted on the frame configured to move between a free position wherein the climbing protection system can move freely along the support member received in the guide structure and a clamping position wherei
