Description

Technical Field

[0001] The utility model belongs to the technical field of sports equipment, and in particular relates to a climbing protection brake. Background Art

[0002] In today's thriving society, people are increasingly interested in and interested in outdoor activities. Sports like rock climbing and mountaineering that require rope protection are rapidly increasing. During both normal climbing activities and emergency rescue operations, significant weight differences between the climber and the belayer at either end of the rope are unavoidable. In previous activities, belay climbing between climbers and belayers with significant weight differences was prohibited to prevent the heavier climber from falling and being dragged off the ground by the lighter belayer.

[0003] Currently, there are no products on the market that can handle belay climbing with climbers and belayers of varying weights. When a lighter belayer is belaying a heavier climber, another belayer must use a device to connect with them and assist them. Alternatively, the belayer can be attached to a ground anchor using auxiliary equipment to prevent the heavier climber from dragging the lighter belayer off the ground and causing a dangerous fall.

[0004] Currently, when a lightweight belayer belays a heavier climber, they must either be assisted by another person or be fixed to a ground anchor. This requires extensive equipment, is cumbersome, and prone to dangerous misoperation. When the belayer is fixed to a ground anchor, their range of motion is limited, making operation inflexible. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a climbing protection brake, which uses friction pins and movable friction pins to generate friction on the rope to reduce the speed of the rope when the climber falls accidentally.

[0006] To achieve the above objectives, the technical solution of the present invention is:

[0007] A climbing protection brake comprises a side plate, a fixed friction pin and a movable friction pin. The side plates are provided with two pieces. The fixed friction pin is installed on the side plates to form a gap between the two side plates. The side plates are also provided with a braking friction force adjustment hole. A gap is provided between the braking friction force adjustment hole and the fixed friction pin, and the braking friction force adjustment holes on the two side plates correspond to each other. The movable friction pin is used to be inserted into the braking friction adjustment hole to form a passage for the rope to pass through the gap between the fixed friction pin and the movable friction pin in the two side plates.

[0008] Furthermore, the width of the channel is greater than the diameter of the rope.

[0009] Furthermore, there are at least two fixed friction pins.

[0010] Furthermore, there are several braking friction force adjustment holes, and the distances between the several braking friction force adjustment holes and the fixed friction pins are different; the movable friction pin is used to be inserted into any of the braking friction force adjustment holes, so as to form a passage for ropes of different widths in the gap between the fixed friction pin and the movable friction pin in the two side plates.

[0011] Furthermore, there are two braking friction force adjustment holes.

[0012] Furthermore, three braking friction force adjustment holes are provided.

[0013] Furthermore, a movable friction pin connecting rope is provided on the side plate, and the movable friction pin connecting rope is used to connect the movable friction pin.

[0014] Furthermore, the climbing protection brake also includes a connecting flat belt and a connecting buckle, the first end of the connecting flat belt is connected to the connecting buckle, and the second end of the connecting flat belt is connected to the flat belt connecting pin fixed on the side panel.

[0015] Furthermore, the two side plates are arranged in parallel, and two fixed friction pins are provided to make the width of the gap between the two side plates consistent.

[0016] The beneficial effects of the utility model are:

[0017] The brake of this utility model has a simple appearance, preventing user errors. It also features a stable and lightweight structure, making it easy to carry and use. When a climber is climbing normally and not falling, the rope between the belayer and the climber is naturally slack as it passes through the brake. The rope does not contact the friction pins, allowing the rope to pass smoothly through the brake without generating friction and impacting the climber or belayer. If the climber unexpectedly falls and the rope is tightened, the rope between the belayer and the brake is bent at a certain angle at the brake. The rope passing through the brake will generate friction with the two fixed friction pins and the movable friction pin, slowing the rope's passage. This provides a buffer between the climber and the belayer with a significant weight difference in the event of a fall, ensuring safety. The brake only generates friction on the rope, reducing its speed, but does not completely stop the rope from passing through the brake, preventing it from interfering with the belayer's belayer.

[0029] See also Figures 1 to 5 A climbing protection brake comprises a side plate 1, a fixed friction pin 2 and a movable friction pin 4. The side plate 1 is provided with two pieces, and the fixed friction pin 2 is installed on the side plate 1 to form a gap between the two side plates 1; the side plate 1 is also provided with a braking friction force adjusting hole 3, and a gap is provided between the braking friction force adjusting hole 3 and the fixed friction pin 2, and the braking friction force adjusting holes 3 on the two side plates 1 correspond to each other. The movable friction pin 4 is used to be inserted into the braking friction adjusting hole 3, so that the gap between the fixed friction pin 2 and the movable friction pin 4 in the two side plates 1 forms a passage for the rope to pass through.

[0030] The two side panels 1 described above can be hollowed out to reduce the brake's own weight and ease the climber's burden. The two side panels 1 are mounted on either end of the fixed friction pin 2, with a gap formed between them. The gap between the brake friction adjustment hole 3 and the fixed friction pin 2 must be at least the same as the diameter of the rope, allowing the rope to pass smoothly through the gap between the fixed friction pin 2 and the movable friction pin 4 in the two side panels 1. The fixed friction pin 2 and the movable friction pin 4 work together to limit the rope's position and provide friction.

[0031] The brake of this utility model has the simplest appearance, which prevents users from operating it incorrectly. At the same time, the brake has the most stable and lightweight structure, making it easy to carry and use. When the climber is climbing normally and does not fall, the rope between the belayer and the climber is naturally relaxed when passing through the brake. The rope does not contact the friction pins, and the rope can pass smoothly through the brake without generating friction, which will not affect the climber or belayer. In the event of an unexpected fall, a buffer can be provided between the climber and the belayer if there is a large weight difference, ensuring safety. When the climber falls, the brake only generates friction on the rope, which reduces the speed of the rope passing through, but does not completely stop the rope from passing through the brake, so it will not conflict with the belayer used by the belayer.

[0032] In an embodiment of the present application, the width of the channel is greater than the diameter of the rope. The width of the channel is greater than the diameter of the rope so that when the climber is climbing normally and does not fall, the rope can pass smoothly through the brake without generating friction and without affecting the climber and the belayer. Under normal circumstances where the climber has not fallen and the rope is not under stress, the rope between the belayer and the climber is naturally relaxed when passing through the brake, and the rope does not contact the friction pins, allowing the rope to pass smoothly through the brake. If the climber accidentally falls and the rope is tightened, the rope between the belayer and the brake and the climber and the brake have a certain angle at the brake. The rope passing through the brake will generate friction with the two fixed friction pins and the movable friction pin, which can slow down the speed of the rope.

[0033] In the embodiment of the present application, at least two fixed friction pins 2 are provided. These fixed friction pins 2 are used to secure the position of the two side panels 1, ensuring a consistent gap between them. The fixed friction pins 2 also cooperate with the movable friction pin 4, allowing the space between them to serve as a passage for the rope. Therefore, the fixed friction pins 2 and the movable friction pin 4 simultaneously exert friction on the rope. Preferably, two braking friction adjustment holes 3 are provided. More preferably, three braking friction adjustment holes 3 are provided.

[0034] In an embodiment of the present application, there are several braking friction force adjustment holes 3, and the distances between the several braking friction force adjustment holes 3 and the fixed friction pins 2 are different; the movable friction pin 4 is used to be inserted into any one of the braking friction force adjustment holes 3, so as to form a passage for ropes of different widths in the gap between the fixed friction pin 2 and the movable friction pin 4 in the two side panels 1.

[0035] Multiple brake friction adjustment holes 3 can be provided to adjust the friction force exerted by the brake on the rope, thereby varying the speed at which the rope passes through the brake. This can reduce or mitigate the impact on the lighter belayer when a heavier climber falls, ensuring the safety of both. When the climber is climbing normally and not falling, the rope can pass smoothly through the brake without generating friction, thus preventing any impact on the climber or belayer. In this application, three brake friction adjustment holes 3 are preferably provided. Three sets of brake friction adjustment holes 3 are positioned to allow for the insertion of a movable friction pin 4, depending on the weight difference between the climber and belayer. The three sets of brake friction adjustment holes 3 adjust the distance between the movable friction pin 4 and the fixed friction pin 2 from farther to closer, respectively. The three different positions are suitable for situations where the climber's weight exceeds the belayer by 10% to 45%, the climber's weight exceeds the belayer by 20% to 70%, and the climber's weight exceeds the belayer by 40% to 100%.

[0036] In the embodiment of the present application, the side plate 1 is further provided with a movable friction pin connecting rope 5, which is used to connect the movable friction pin 4. The movable friction pin connecting rope 5 passes through the hole at one end of the movable friction pin 4 and is connected to the brake side plate 1. The movable friction pin connecting rope 5 can prevent the movable friction pin 4 from being accidentally lost when it is removed.

[0037] In an embodiment of the present application, the climbing protection brake further includes a connecting flat strap 7 and a connecting buckle 8. The first end of the connecting flat strap 7 is connected to the connecting buckle 8, and the second end of the connecting flat strap 7 is connected to a flat strap connecting pin 6 fixed to the side panel 1. The flat strap connecting pin 6 passes through the two parallel side panels 1 and is fixed thereto. Two fixed friction pins 2 and the flat strap connecting pin 6 secure the two parallel side panels 1 and maintain a constant distance between them. A loop at one end of the connecting flat strap 7 is positioned between the two parallel side panels 1. The flat strap connecting pin 6 passes through the loop at one end of the connecting flat strap 7 to connect it to the two brake side panels 1 and other components. The loop at the other end of the connecting flat strap 7 is connected to the connecting buckle 8, which can be used to hang the entire brake at a protection point on the rock wall.

[0038] In the embodiment of the present application, the two side plates 1 are arranged in parallel, and two fixed friction pins 2 are provided to make the width of the gap between the two side plates 1 consistent.

[0039] During use, the space enclosed by the two side panels 1, two fixed friction pins 2, and a movable friction pin 4 inserted through a brake friction adjustment hole 3 is used to pass a rope. The rope passing through the brake is connected to the climber at one end and the belayer at the other. As the rope passes through, friction is generated between the fixed friction pins 2 and the movable friction pin 4, slowing the rope's speed. Because the brake friction adjustment holes 3 have three different positions, the movable friction pin 4 inserted in each position has a different distance from the fixed friction pins 2, generating correspondingly different friction forces on the rope passing through the brake. A flat strap connecting pin 6, a connecting flat strap 7, and a connecting buckle 8 secure the entire brake, with the rope passing through it, to the rock face at a belay point. Selecting one of the three brake friction adjustment holes 3 ensures that the rope receives the appropriate friction force, thereby increasing the rope's speed. This mitigates the impact of a heavy climber falling on a lighter belayer, ensuring the safety of both.

Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
