Abstract
Description
[Technical Field]
[0001] The present invention relates to an ascender winch and a rope climbing method using an ascender winch.
[0002] When a person ascends to a high place using a rope, they generally use a handled ascender, a chest ascender, and foot cords, and climb by manually shifting the load between the handled ascender and the chest ascender.
[0003] 6 and 7 are schematic diagrams showing a situation in which climber H ascends a rope using a conventional method. Climber H grasps rope 1 suspended from the wall of a building or the like to ascend. Climber H wears a full harness 3, which may be a combination of a seat harness and a chest harness, and ascenders connected to the full harness 3 are a handle-equipped ascender 4 and a chest ascender 5. The handle-equipped ascender 4 is connected to the full harness 3 by, for example, a fall prevention cord (not shown), and the chest ascender 5 is attached directly to the full harness 3, for example.
[0004] The handle-equipped ascender 4 and chest ascender 5 are specialized devices for ascending ropes, commonly known as ascenders. The ascender has a frame and a cam, with multiple downward-pointing protrusions protruding from the cam. The rope is sandwiched between the frame and the cam, and when a downward load is applied, the rope is compressed by the frame and the cam, and the downward protrusions protruding from the cam bite into the rope, preventing the ascender from slipping off the rope and maintaining its position. Therefore, even if a climber applies their own weight to the ascender, the ascender will not slide down. Conversely, if the climber releases their load from the ascender, the downward-pointing protrusions on the cam allow it to be removed from the rope. In other words, the climber can slide the ascender upward on the rope while it is still holding the rope.
[0005] When climbing, if climber H applies his / her weight to the ventral ascender 5, the weight is removed from the handled ascender 4, allowing the handled ascender 4 to slide upward. Conversely, if climber H applies his / her weight to the handled ascender 4, the weight is removed from the ventral ascender 5, allowing the handled ascender 4 to slide upward. By switching the load between these two ascending devices, a person can ascend the rope. Furthermore, since it is difficult to support one's weight with one or both arms when applying one's weight to the handled ascender 4, a foot cord 6 is attached to the handled ascender 4. The tip 6a of the foot cord 6 has a loop on which climber H can place his / her feet, and by placing one or both feet on the tip 6a of the foot cord 6, climber H can support his / her weight with his / her feet. The climber H supports his / her own weight with one or both arms holding the handle-equipped ascender 4 and one or both feet at the tip 6a of the foot cord 6, thereby making it possible to remove the weight from the chest ascender 5.
[0006] As shown in Figure 6, when climber H is hanging from the ventral ascender 5, the entire weight is placed on the ventral ascender 5, which, due to the characteristics of the climbing device described above, does not slide downward and remains fixed to the rope 1. At this time, no weight is placed on the arm or arms holding the handled ascender 4, or the foot cord 6 holding one or both feet. Therefore, by climbing person H relaxing his or her arms, he or she can slide the handled ascender 4 upward with one or both arms. Also, by climbing person H simultaneously bending one or both feet, the foot cord 6 can be moved upward along with the handled ascender 4.
[0007] Next, climber H, while holding rope 1 and / or handled ascender 4 with one or both arms, applies force to bend his / her arms, and while bracing with his / her feet on the tips 6a of foot cords 6, extends his / her legs as if intending to stand up on foot cords 6. This action causes climber H to pull the part of his / her body above the knees upward relative to the rope 1, as shown in Figure 7, and he / she stands up. At this time, a downward load is applied to the handled ascender 4, but due to the characteristics of the climbing device, the handled ascender 4 does not slide downward and remains fixed to the rope 1. Meanwhile, as climber H moves upward, the ventral ascender 5 slides upward along the rope 1, and its position rises.
[0008] In the state shown in Figure 7, when the arms and legs are relaxed from the handled ascender 4 and foot cords 6, the entire weight is placed on the ventral ascender 5. At this time, the position of the handled ascender 4 is lower relative to climber H than in the state shown in Figure 6. From this state, climber H uses his arms to slide the handled ascender 4 upward along the rope 1, while also relaxing and bending his legs, moving the foot cords 6 upward along with the handled ascender 4. This action raises climber H above the original position shown in Figure 6 relative to the rope 1, returning his posture to the state shown in Figure 6. In this way, climber H can ascend by alternately transferring weight between the handled ascender 4 and the ventral ascender 5.
[0009] This example is one method for ascending a single rope, but there are other methods for a person to ascend a rope, such as the Frog system, in which both feet are placed in the foot cords 6, and the Mitchell system, which uses an ascender with two handles. Also, for safety reasons, a backup rope and backup device are usually connected to climber H, but this will not be explained in this description. Also, climber H generally holds a descender for descending the rope, but this will not be explained in this description.
[0010] However, with manual ascents, including the methods shown in Figures 6 and 7, once the worker has climbed a certain distance (e.g., about 30 m), lactic acid builds up in the arms and legs, hindering subsequent work. For example, some rope access sites, such as bridges, dams, and plants, require workers to climb several hundred meters in height. At such sites, if the worker forgets even a little about the work they were doing above, they must climb back up manually even after starting to descend using a descender. However, climbing back up after completing the work is physically and mentally demanding, and many workers simply ignore the situation and continue descending without climbing back up.
[0011] In order to reduce the effort required for such manual climbing, a power ascender that reels in a rope has been developed (Patent Document 1). [Prior art documents] [Patent documents]
[0012] [Patent Document 1] Patent No. 6056113 specification Summary of the Invention [Problem to be solved by the invention]
[0013] The power ascender described above uses power and can reduce the effort required for manual climbing, but current power ascenders are large, heavy, and expensive, so they have not yet become widespread.
[0014] The present invention relates to an ascender winch and a rope climbing method using an ascender winch, which has a simple configuration and low cost and can significantly reduce the effort required for climbing compared to climbing using only human power. [Means for solving the problem]
[0015] The present invention provides A winding body capable of winding up a long object having an end to which an ascender for rope climbing can be attached; a power source that rotates and drives the winding body; a housing that accommodates at least the winding body and is attachable to the body of a climber ascending the rope; Equipped with The elongated object connected to the winding body inside the housing can have the ascender attached to the end portion in a state where the elongated object protrudes from the inside to the outside of the housing, The power source is driven to rotate the winding body, thereby winding up the long object, and the long object wound on the winding body can be pulled out from the housing. This is an ascender winch.
[0016] The present invention also provides A rope climbing method using an ascender winch, comprising: An ascender's winch having a winding body capable of winding up a long object is attached to the body of a climber ascending a rope, An ascender for climbing a rope is attached to one end of the long object connected to the winding body, With the long object pulled out from the ascender winch, the ascender is fixed to the rope; a power source that rotates and drives the winding body, thereby rotating and driving the winding body, and thereby winding the long material onto the winding body; After the climber's body is raised by winding the long object, the long object is pulled out from the ascender winch, and the ascender is fixed to the rope again at a position higher than the original position. This is a rope climbing method using an ascender winch. [Effects of the Invention]
[0017] According to the present invention, when the power source is driven to wind up the long object, the climber's body rises, i.e., the climber can climb with the support of the power source, so the effort required for climbing can be significantly reduced with a simple configuration and low cost compared to climbing using only human power.

[0019] The following is a detailed description of an ascender winch and a rope climbing method using an ascender winch according to an embodiment of the present invention. Note that the present invention is not limited to the embodiments described below, and can be modified and implemented as desired without departing from the spirit and scope of the present invention.
[0020] FIG. 1 is a schematic diagram showing a situation in which a climber H ascends a rope 1 using an ascender's winch 10 according to an embodiment of the present invention. The climber H ascends by grasping the rope 1 suspended from the wall of a building or the like. The climber H is wearing, for example, a full harness 3, as in the past. A chest ascender 5 for rope ascent is connected to the full harness 3, as in the past. A handled ascender 4 for rope ascent is also fixed to the rope 1 in the same manner as in the past, but as will be described later, the handled ascender 4 is connected to the ascender's winch 10 via a sling belt 20.
[0021] Furthermore, the ascender's winch 10 according to the embodiment is attached to the D-ring of the full harness 3 via a connector such as a swivel or carabiner. The foot cord 6 shown in Figs. 6 and 7 is not essential but may be included. In this example, the ascender's winch 10 is attached to the full harness 3, but it may be attached to the body of the climber H. The chest ascender 5 is also attached to the full harness 3, but it may be attached to the trunk of the climber H.
[0022] A long sling belt 20 is attached to the ascender winch 10, and one end of the sling belt 20 is connected to the handle-equipped ascender 4 via, for example, a connector. As will be described later, the ascender winch 10 has a power source such as a motor, and the sling belt 20 can be wound inside by the action of the power source. The wound sling belt 20 can also be pulled out, for example, manually. Figure 1 shows the sling belt 20 pulled out from the ascender winch 10. With the sling belt 20 pulled out from the ascender winch 10, the climber H secures the handle-equipped ascender 4 to the rope 1.
[0023] FIG. 2 is an external view showing the appearance of an ascender's winch 10 and an ascender with a handle 4 according to an embodiment. The ascender's winch 10 has a housing 11 that can be attached to the body of an ascender H ascending the rope 1. The housing 11 is made of, for example, metal, resin, or the like. A connector 7, such as a carabiner, is attached to the housing 11, and the connector 7 is attached to, for example, a D-ring on a full harness 3. In addition, a flexible, long sling belt 20 protrudes from the inside to the outside of the housing 11, and the ascender with a handle 4 can be attached to its end 20a. The sling belt 20 has high load-bearing capacity, but the long object does not have to be a sling belt; it can be a belt, string, rope, or the like that can be wound up inside the housing 11.
[0024] The handle-equipped ascender 4, which can be held by the climber's hand, has a configuration similar to that of conventional products. The handle-equipped ascender 4 has a frame 4a and a cam 4b, made of, for example, a metal. The cam 4b is rotatably attached to the frame 4a and is normally biased toward the frame 4a by a spring (not shown). During ascent, the rope 1 is sandwiched between the frame 4a and the cam 4b. The cam 4b has multiple downward-facing pointed protrusions. If a downward load is applied to the rope 1, the rope 1 is compressed by the frame 4a and the cam 4b, and the downward protrusions protruding from the cam 4b bite into the rope 1. This series of actions prevents the handle-equipped ascender 4 from slipping off the rope 1 and allows it to maintain its position. In other words, even if climber H holds the handle-equipped ascender 4 in his or her hand and applies his or her own weight downward, the handle-equipped ascender 4 will not slip down.
[0025] Conversely, when climber H removes the weight from the handled ascender 4, the protrusion of cam 4b faces downward, allowing it to be removed from the rope 1. When climbing, if climber H applies his / her own weight to the ventral ascender 5, for example, the weight will be removed from the handled ascender 4, allowing the handled ascender 4 to slide upward, and conversely, if climber H applies his / her own weight to the handled ascender 4, the weight will be removed from the ventral ascender 5, allowing the handled ascender 5 to slide upward.
[0026] The handle-equipped ascender 4 has handle holes 4c formed in the frame 4a, making it easy for the climber H to grip with his / her hands. However, the handle holes 4c are not essential, and a simple ascender without handle holes 4c can be used instead of the handle-equipped ascender 4. The handle-equipped ascender 4 is connected to the end 20a of the sling belt 20 via a connector 9.
[0027] FIG. 3 is a front view showing the interior of an ascender winch 10 according to an embodiment. In this figure, the cover 11b of the housing 11 (see FIG. 4) has been removed to show the interior of the ascender winch 10, and the connector 7 has been omitted. The ascender winch 10 has a bobbin 16, which is a take-up body capable of taking up the sling belt 20, and a motor 12, which is a power source that rotates and drives the bobbin 16. The ascender winch 10 also has a reducer 13 that is mechanically connected between the motor 12 and the bobbin 16 and reduces the rotation speed of the motor 12 to output a predetermined torque to the bobbin 16. The bobbin 16, motor 12, and bobbin 16 are housed in a main housing portion 11a, which constitutes the main part of the housing 11.
[0028] Although a battery, which is a power source for driving the motor 12, is not shown in the drawings, the battery may be separate from the housing 11 and connected to the housing 11 by a cable, or may be provided so as to be detachable from the housing 11. Furthermore, although a switch for controlling switching of the operation of the motor 12 is not shown in the drawings, the switch may be separate from the housing 11 and operable remotely, or may be provided directly on the housing 11.
[0029] FIG. 4 is an exploded perspective view of the ascender winch 10 according to the embodiment. As described above, the housing 11 has a main housing portion 11a constituting the main part and a lid portion 11b that covers the inside of the main housing portion 11a. The motor 12, the reducer 13, and the bobbin 16 are disposed in the internal space defined by the main housing portion 11a and the lid portion 11b. A passage hole 11c is provided on the side of the main housing portion 11a, through which the sling belt 20 passes, allowing the sling belt 20 to protrude from the inside to the outside of the housing 11 (the sling belt 20 is not shown). The main housing portion 11a also has a connecting hole 11d to which the connecting tool 7 (see FIG. 2) can be connected (the connecting tool 7 is not shown).
[0030] In this embodiment, the reducer 13 has a rectangular parallelepiped shape including one surface 13a. The motor 12 is disposed on the one surface 13a of the reducer 13 and is connected to multiple gears (not shown) disposed inside the reducer 13. The multiple gears are connected to a rotating shaft 15 on the output side, and the rotating shaft 15 protrudes from the one surface 13a, passes through a central hole 16a formed at the rotation center of the bobbin 16, and is fixed to the central hole 16a. That is, the motor 12 and the bobbin 16 are disposed side by side on the one surface 13a of the reducer 13 inside the housing 11. The reducer 13 may be, but is not limited to, a bevel reducer, a planetary gear reducer, a cycloid reducer, or the like. A geared motor may also be used instead of the motor 12 and the reducer 13.
[0031] When climber H operates the switch to drive motor 12, it rotates bobbin 16. For example, when bobbin 16 rotates in the direction of arrow A in Fig. 3, bobbin 16 can take up sling belt 20 that has been pulled out from housing 11. Conversely, when bobbin 16 rotates in the direction of arrow B in Fig. 3, sling belt 20 that has been wound around bobbin 16 can be pulled out from housing 11. Sling belt 20 that has been wound around bobbin 16 may be manually pulled out of housing 11 by climber H using his or her hands.
[0032] Furthermore, the through hole 11c of the housing 11 may be provided near an edge 16b of the bobbin 16 from which the sling belt 20 is led out from the bobbin 16. The edge 16b corresponds to the outer edge of the bobbin 16, which is circular in plan view.
[0033] FIG. 5 is a schematic diagram showing the situation when climber H ascends the rope 1 using the ascender's winch 10 from the state shown in FIG. 1. From the state shown in FIG. 1, climber H operates a switch (not shown) to drive motor 12. Driven by motor 12, bobbin 16 is rotated in the direction of arrow A in FIG. 3 via reducer 13, and sling belt 20 is wound up. Because handle-equipped ascender 4 is fixed to rope 1 and ascender's winch 10 is fixed to full harness 3, winding up sling belt 20 moves ascender's winch 10 closer to handle-equipped ascender 4. A downward load is applied to handle-equipped ascender 4, but it does not shift downward. As a result, full harness 3 connected to ascender's winch 10, and ultimately the body of climber H wearing full harness 3, rises. Since no weight is applied to the chest ascender 5, the chest ascender 5 slides upward along the rope 1 as the climber H's body rises.
[0034] After the climber H has ascended, the switch is operated to stop the motor 12, and in the state shown in Figure 5, the handle-equipped ascender 4 is positioned lower relative to the climber H than in the state shown in Figure 1. When the climber H manually slides the handle-equipped ascender 4 upward along the rope 1 as shown by the arrow, the bobbin 16 rotates in the direction of arrow B in Figure 3, and the wound sling belt 20 can be pulled out from the ascender winch 10.
[0035] As a result, the handle-equipped ascender 4 is fixed at a position higher than the original position shown in Figure 1, and the climber H's body rises while his / her posture returns to the state shown in Figure 1. In this way, the climber H can ascend by alternately winding up the sling belt 20 with the ascender winch 10 and pulling out the sling belt 20 by sliding the handle-equipped ascender 4 upward.
[0036] As described above, with the ascender's winch 10 according to the embodiment and the rope climbing method shown in Figures 1 and 5, the motor 12 is driven to wind up the sling belt 20, causing the climber H's body to ascend. In other words, since the climber H can ascend with the assistance of the motor 12, the effort required for climbing can be significantly reduced with a simpler configuration and lower costs compared to climbing solely by human power.
[0037] Furthermore, according to the embodiment, heat stroke can be prevented, work efficiency can be increased, climber H can easily concentrate on the actual work he / she is supposed to do, and the quality of work is expected to improve. Furthermore, since it reduces soiling of clothes, it is expected that the satisfaction of the people involved at the work site will also increase. Note that Figures 1 and 5 show a situation in which climber H simply places one hand on the handle-equipped ascender 4, and climber H does not actually need to use both arms.
[0038] Furthermore, in the ascender winch 10 according to the embodiment, the housing 11 houses the motor 12, the reducer 13, and the bobbin 16. Therefore, it is possible to reduce the size while storing the main components in the housing 11. In particular, because the motor 12 and the bobbin 16 are arranged side by side on one surface 13a of the reducer 13 inside the housing 11, it is possible to reduce the size based on a specific design.
[0039] However, the housing 11 does not necessarily have to house the motor 12 and the reducer 13 as long as it can pull up the body of the climber H connected to the housing 11 by winding up the sling belt 20. For example, the power source and / or the reducer may be incorporated into an external device, for example, a portable tool such as a charging driver. When a charging driver is used, the charging driver itself can serve as the motor and the reducer. The climber H can connect the output shaft of the charging driver to the rotation center of the bobbin 16 of the housing 11 and turn on the charging driver, thereby rotating the bobbin 16 and winding up the sling belt 20.
[0040] In this embodiment, the sling belt 20 wound around the bobbin 16 can be manually pulled out from the housing 11. Therefore, the sling belt 20 wound inside the housing 11 can be pulled out from the housing 11 without providing any additional components. However, a braking mechanism that prohibits manual pulling out of the sling belt 20 may be provided. In this case, the braking action of the braking mechanism may be released by a predetermined operation, allowing the sling belt 20 to be pulled out.
[0041] In this embodiment, the passage hole 11c through which the sling belt 20 passes is provided in the housing 11 near the edge 16b of the bobbin 16. This configuration prevents the sling belt 20 from interfering with other parts inside the housing 11.
[0042] The ascender may be an ascender 4 with a handle that can be held by the climber's hand. This makes it possible to effectively utilize the characteristic of the ascender 4 with a handle that it will not slip down even when a load is applied.
[0043] Furthermore, in the rope climbing method according to this embodiment, when the climber H's body ascends by winding up the sling belt 20, the ventral ascender 5 slides upward on the rope 1. This allows the ventral ascender 5 to support the climber H's body, thereby improving safety.
[0044] As a result, the present disclosure describes at least the following: Note that the components in parentheses correspond to those in the above-described embodiments, but are not limited to these.
