专利汇可以提供Climbing aid专利检索，专利查询，专利分析的服务。并且Climbing aid structure includes a grappling hook. A throw line and a climbing line are attached to the grappling hook. The throw line is thrown over an overhead support (such as a tree limb), and the grappling hook is emplaced by manipulation of the throw and climbing lines. The climbing line is then oriented in an upright position and tensioned by use of a ground anchor. Handand-foot engaging, line-gripping elevator devices are positioned on the climbing line for ascent of the line by a climber. The line-gripping devices include levers which wedge against the rope under the weight of a climber, to grip the rope and provide support for the climber to ascend the climbing line.，下面是Climbing aid专利的具体信息内容。
1. Climbing aid structure, comprising a climbing line, at least one line-gripping means operatively associated with the climbing line, each of the line-gripping means including a frame, first and second support members carried by the frame, the first and second support members projecting outwardly in opposite directions relative to the climbing line, a first wedging surface operatively associated with the first support member, a second wedging surface operatively associated with the second support member, and mounting means mounting the first support member for swinging movement between a first position in which the first wedging surface opposes the second wedging surface and the climbing line is wedged between the first and second wedging surfaces to prevent movement of the line-gripping means relative to the climbing line, and a second position in which the first wedging surface is out of wedging relation to the climbing line and the line-gripping means is free to move relative to the climbing line, grappling hook means for grappling an overhead supporting member, and a throw line for pulling the grappling hook means up to the overhead supporting member, the grappling hook means including an arm and an open side, the arm extending from a first end portion contiguous to the open side to a free second end portion, throw line connecting means contiguous to the first end portion of the arm, and climbing line connecting means contiguous to the second end portion of the arm.
2. The structure of claim 1, including second mounting means mounting the second support member for swinging movement between a first position in which the second wedging surface opposes the first wedging surface and the climbing line is wedged between the first and second wedging surfaces to prevent movement of the line-gripping means relative to the climbing line, and a second position in which the second wedging surface is out of wedging relation to the climbing line and the line-gripping means is free to move relative to the climbing line.
3. The structure of claim 1, including two line-gripping means serially arranged along the climbing line, one of the line-gripping means including bracket means operatively associated with each of the first and second support members for retaining a foot of a climber, each bracket means including a retaining portion extending along the support member and spaced from the support member in a direction toward the other line-gripping means.
4. The structure of claim 1, including a locking member interposed between the climbing line and the first support member, the first wedging surface having a curved configuration, the locking member having a line-contacting surface which is generally complementary in shape to the climbing line, the locking member also having a curved force-receiving surface which is opposite the line-contacting surface and which is generally complementary in shape to the first wedging surface, the first wedging surface acting through the locking member to wedge the climbing line against the second wedging surface.
5. The structure of claim 1, including second mounting meaNs mounting the second support member in fixed position.
6. The structure of claim 1, the first wedging surface having a generally semi-circular configuration, the first support member being elongated and having a longitudinal axis, the mounting means comprising a pivot member spaced in a direction along the climbing line from the axis of the first support member.
7. The structure of claim 1, including clip means at a location opposite the open side for releasably retaining the climbing line.
8. The structure of claim 1, the grappling hook means including a portion inclined in a direction away from the arm for bypassing the overhead supporting member.
9. The structure of claim 1, including ground-anchoring means for anchoring at least a portion of the climbing line in a generally upright position below the grappling hook means.
10. The structure of claim 9, including means for maintaining tension in the upright portion of the climbing line.
11. Climbing aid structure, comprising grappling hook means for grappling an overhead supporting member, a throw line for pulling the grappling hook means up to the overhead supporting member, the grappling hook means including an arm and an open side, the arm extending from a first end portion contiguous to the open side to a free second end portion, throw line connecting means contiguous to the first end portion of the arm, and climbing line connecting means contiguous to the second end portion of the arm.
12. The structure of claim 11, including clip means at a location opposite the open side for releasably retaining the climbing line.
13. The structure of claim 11, the grappling hook means including a portion inclined in a direction away from the arm for bypassing the overhead supporting member.
14. Climbing aid structure, comprising grappling hook means for grappling an overhead supporting member, the grappling hook means including an arm and an open side, the arm extending from a first end portion contiguous to the open side to a free second end portion, first line-connecting means contiguous to the first end portion of the arm, and second line-connecting means spaced from the first line-connecting means and contiguous to the second end portion of the arm, a throw line operatively associated with one of the line-connecting means for pulling the grappling hook means up to the overhead supporting member, a climbing line operatively associated with the other line-connecting means, ground-anchoring means for anchoring at least a portion of the climbing line in a generally upright position below the grappling hook means, means for maintaining tension in the upright portion of the climbing line, and line-gripping elevator means for ascending the upright portion of the climbing line.
