Carabiner for retaining tool

Abstract

To provide a carabiner for retaining that reduces a burden in keeping a state where a retaining person pulls and stops a rope after stopping crash of a climber.SOLUTION: A rope winding tool 3 is provided in the outside in the vicinity of a center part of a main shaft 1 of a carabiner for retaining. A horizontal-displacement preventing tool 4 is provided in a portion in the inside in which the main shaft 1 and a lateral shaft 2 cross with each other. A rope 8 is made to pass through a retainer 7, a gate 5 of the carabiner for a retainer is opened, and the lateral shaft 2 is made to pass through a rope opening part 9. A belay loop 14 of a harness 15 is made to pass from a gate opening part 6, the gate 5 is closed, and belay loop 14 is hooked on the carabiner for retaining. A retaining person stops a crash of a climber, and then winds a terminal side rope 11 around the rope winding tool 3 one time, so that the retaining person can keep a state of stopping only by lightly gripping and pulling the rope by right hand 12 and left hand 13.SELECTED DRAWING: Figure 4

Description

[Technical Field]

[0001] The present invention relates to a carabiner for use with a rock climbing belay device. [Background technology]

[0002] Traditionally, carabiners for belay devices have been either carabiners with a protrusion on the upper shoulder on the opposite side of the gate to prevent the belay device from sliding sideways, or HMS carabiners. [Prior art documents] [Non-patent literature]

[0003] [Non-Patent Document 1] KEM2024-2025 original catalog, p.16 Summary of the Invention [Problem to be solved by the invention]

[0004] Conventional carabiners for belay devices have the following drawbacks: (i) The rope attached to the climber's harness is connected to the belay device and carabiner of the belay device by way of anchors and quickdraws on the climbing wall, and if the climber falls while climbing, the belay device can use these to arrest the fall. After that, the belay device must hold the rope tightly to prevent the climber from falling until the climber starts climbing again. (b) During belaying, the belay device sometimes shifted sideways on the horizontal axis of the belay device carabiner. The present invention has been made to solve the above problems. [Means for solving the problem]

[0005] A rope winding device 3 is provided on the outside near the center of the main shaft 1, and a lateral slippage prevention device 4 is provided on the inside part where the main shaft 1 and horizontal shaft 2 intersect. A securing carabiner having the above configuration. [Effects of the Invention]

[0006] By using this invention, when a climber falls, the rope tied to the belay loop of the climber's harness passes through an anchor and quickdraw attached to the climbing wall, and then leads to a belay device and a carabiner for the belay device, and the belay person can grab this rope to stop the climber's fall. The belayer then winds the rope around the rope reel 3 of the belay carabiner to increase frictional resistance and secure the rope. At this time, it is much easier to grasp and secure the rope than if the rope were not wound around the rope reel 3. When the climber begins climbing again, he removes the rope from the rope reel 3 and begins belaying. Furthermore, when rappelling on rocky terrain using a belay device and carabiner, the use of the belay carabiner of the present invention allows for easy restraint by winding the rope around the rope winding device 3 even while rappelling.

DETAILED DESCRIPTION OF THE INVENTION

[0008] Hereinafter, an embodiment of the present invention will be described. (i) A rod-shaped shaft about half the length of the main shaft 1 is provided on the outside of the center of the main shaft 1, at a distance of about the diameter of the rope. (b) A lateral slip prevention device 4 is provided at the inner part where the main shaft 1 and the horizontal shaft 2 intersect. When using the present invention, the rope 8 is passed through the belay device 7, the gate 5 of the belay device carabiner is opened, and the horizontal shaft 2 is passed through the rope opening 9. The belay loop 14 of the harness 15 is also passed through the gate opening 6, and the gate 5 is closed and hooked onto the belay carabiner. In this position, the belayer secures the climber, holding the climber's rope 10 in his right hand 12 and the terminal rope 11 in his left hand 13. If the climber falls, the belayer lightly grasps the climber's side of the rope with his right hand 12 and firmly grasps and pulls the terminal rope 11 with his left hand 13, thereby preventing the climber's fall through the friction between the rope and the belay carabiner. After that, the climber must continue to firmly grasp and pull the rope until he begins to climb. However, by using the belay carabiner of the present invention, by wrapping the terminal rope 11 around the rope spool 3 once, the belayer can be secured by simply lightly grasping and pulling with his right hand 12 and left hand 13. Wrapping it twice will ensure a more complete stop. If the belay carabiner is used in reverse, the right and left hands are reversed. Furthermore, after a climber falls, the movements of the climber or the belay person may cause the belay device 7 to shift toward the rope winding device 3. However, the carabiner for belay devices of the present invention is equipped with a lateral slippage prevention device 4, so the belay device 7 hardly shifts sideways and remains in the center. Furthermore, because the belay device 7 is in the center of the horizontal axis 2 when winding the distal rope 11 around the rope winding device 3, the rope is less likely to hit the belay device 7 and cause an obstruction.
