Summary of the Invention

Problems to be Solved by the Invention

[0004] [[ID=孔]]However, although the conventional glove has a non-slip hard pin, a certain level of grip strength is required to reliably hold the rope, and when the grip strength decreases due to frostbite or the like, it becomes difficult to reliably hold the rope.

[0005] Therefore, the present invention solves such problems and aims to provide a device that can reliably hold a rope or the like even when the grip strength is small. <舍 Rope locking device

Means for Solving the Problems

[0006] To achieve the above object, in the present invention, a glove (1) is provided with a ring-shaped locking band (2) that is locked to the wrist along the outer periphery of the wrist of the hand (H) inserted into the glove (1), and a part of the locking band (2) serves as a connecting part (22) that receives a load The palm side of glove (1) and A locking device (4) is connected to the connecting portion (22), and the locking device (4) is equipped with a pair of side plates (41, 42), and a pair of friction members (44, 45) are provided between the side plates (41, 42) which are spaced apart and facing each other at a predetermined interval, and the rope (R) that passes between these friction members (44, 45) and extends toward the palm side is held down by the fingers of a hand inserted into the glove (1), causing the rope (R) to bend in the portion that passes between the friction members (44, 45), so that the surface of the rope presses against each of the friction members and is locked in place by frictional force. . It should be noted that there seems to be some incorrect or unclear parts in the original text, such as "<舍 " and "<舍 Rope locking device " which may be typos. The translation is based on the best understanding of the overall context.

[0007] This invention In this configuration, when a load is applied to the connecting part, this load is transmitted to the entire locking band and supported by the wrist of the hand placed in the glove. Therefore, even if the grip strength of the hand is insufficient, the load can be reliably supported by the wrist. Furthermore, a secure locking mechanism can be achieved with a simple structure. .

[0012] As described above, the gloves of the present invention allow for secure holding of ropes and the like, even when grip strength is low. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0014] Note that the embodiments described below are merely examples, and various design improvements made by those skilled in the art without departing from the gist of the present invention are also included in the scope of the present invention.

[0015] FIG. 1 shows a plan view of the glove 1 to be worn on the right hand as viewed from the back side. When a glove to be worn on the left hand is required, its structure is substantially the same as that of the right-hand glove 1 described below. Similar to a normal glove, the glove 1 includes a main bag 11 for inserting the main body of the hand, and finger bags 12 to 15 for inserting the thumb and the other four fingers, respectively, with their proximal ends opening into the main bag 11 (the finger bag of the thumb is hidden in FIG. 1).

[0016] The main bag 11 of the glove 1 is open downward in FIG. 1, and at the opening edge 111, the wrist is located when the hand is inserted into the main bag 11. The opening edge 111 is cut open at one place in the circumferential direction, a tongue-like piece 112 is formed on one side of the cut edge (not shown), and a surface fastener 113 is provided on the other side of the cut edge. The surface fastener on the back surface of the tip of the tongue-like piece 112 is detachably coupled thereto to tighten the wrist.

[0017] FIG. 2 shows the state where the above opening edge 111 is turned inside out. Along the inner circumference of the opening edge 111, a locking band 2 formed in a ring shape with a certain width is disposed. The locking band 2 is sewn to the opening edge 111 at one place 21 where its both ends are overlapped. As shown in FIG. 3, a part of the locking band 2 is drawn out of the glove 1 through through-holes 113 and 114 provided at two left and right positions on the palm side of the main bag 11 close to the opening edge 111 to form a connecting portion 22. Therefore, in the normal use state where the opening edge 111 of the main bag 11 is not turned inside out, the locking band 2 is located mainly along the outer circumference of the back side of the wrist of the hand inserted into the main bag 11, and the connecting portion 22 is exposed on the palm side of the main bag 11. Note that the reference numeral 16 in FIG. 3 is the finger bag for inserting the thumb.

[0018] In the present embodiment, as shown in FIG. 4, a carabiner 3 is attached to the connecting portion 22 as a connector. The carabiner 3 is formed by shaping a metal rod into an oval shape, with an opening at one location in the circumferential direction. A screw cylinder 31 is screwed onto male screw portions formed on the outer peripheries of both ends of the metal rod facing each other across the opening, and by rotating this forward and backward, the opening is opened and closed (FIG. 4 shows a state where the opening is open).

[0019] As shown in FIG. 5, a locking tool 4 is connected to the carabiner 3 (FIG. 5 shows a state where the opening of the carabiner 3 is closed). Details of the locking tool 4 are shown in FIGS. 6 to 8. FIG. 6 is a plan view of the locking tool 4, FIG. 7 is a right side view of FIG. 6, and FIG. 8 is a left side view of FIG. 6.

[0020] The locking tool 4 includes left and right long plate-shaped side plates 41 and 42 that are bent and formed symmetrically in a plan view. Through holes 43 (FIGS. 7 and 8) through which the carabiner 3 is inserted and connected are formed in each half portion 411 and 421 of the side plates 41 and 42 that are in contact with each other. Between half portions 412 and 422 of the left and right side plates 41 and 42 that face each other with a gap therebetween, shaft bodies 441 and 451 are installed between mounting holes (not shown) provided at the tip and the middle thereof, respectively, and friction rollers 44 and 45 whose rotation is restricted as friction members are attached to each of the shaft bodies 441 and 451.

[0021] The friction roller 44 is made of metal, and a large number of grooves extending in the axial direction are formed adjacent to each other in the circumferential direction on its outer periphery, forming unevenness that generates frictional force. One end surface of the friction roller 44 has a protruding pin (not shown) inserted into any one of a plurality of small holes 413 (FIG. 8) formed on the plate surface around the mounting hole of the side plate 41, and its rotation is restricted.

[0022] The friction roller 45 has a similar structure to the friction roller 44, but the mounting holes 414 and 423 (Figures 7 and 8) that receive the shaft 451 (Figure 8) on which the friction roller 45 is mounted are elongated holes that extend in the direction of the shaft 441 (Figure 9). By moving the shaft 451 along the mounting holes 414 and 423, the distance of the friction roller 45 from the friction roller 44 can be changed and adjusted. Multiple small holes 415 (Figure 9) are formed at intervals on both sides of the mounting hole 414, and by inserting a pin 452 (Figure 9) protruding from one end face of the friction roller 45 into one of the small holes 415, the friction roller 45 is positioned in the direction of the elongated hole and its rotation is restricted.

[0023] When using the gloves described above for rescue operations using ropes, as shown in Figure 5, connect the fastener 4 to the carabiner 3, then insert your right hand H into the glove 1 (Figure 10), and pass the rope R vertically between the upper and lower friction rollers 44 and 45 of the fastener 4. In this state, if you appropriately hold down the portion of the rope extending downward from between the friction rollers 44 and 45 with the middle or ring finger of your right hand H, the rope R will pass vertically between the friction rollers 44 and 45 in a curved, V-shape.

[0024] In this state climber When the body load is applied from the glove 1 to the locking device 4, the upper and lower sides of the curved rope R are pressed against the circumferential surfaces of the upper friction roller 44 and the lower friction roller 45, and the locking device 4 is prevented from moving downward along the rope R by frictional force, thus becoming locked.

[0025] At this time, a load reaction force acts on the glove 1 via the carabiner 3, but this load reaction force is transmitted from the carabiner 3 through the connecting part 22 to the entire locking belt 2 and received mainly on the back of the wrist of the right hand H. This ensures that even if the climber's grip strength is insufficient, the climber's body load is reliably supported by their wrist. To release the locking state, the load on the locking device 4 should be reduced. When the load is reduced, the rope R returns to a straight direction, the pressure on the friction rollers 44 and 45 is released, and the locking device 4 (and the glove 1 connected thereto) can be moved along the rope R.

[0026] The above describes the right-hand glove, but the left-hand glove has a similar structure, and a similar fastener is attached to it. By placing both hands in the gloves and passing the fasteners attached to each glove through the same rope with the fasteners positioned above and below each other, the rope can be raised and lowered by alternately locking (loaded) and unlocking (unloaded) the upper and lower fasteners.

[0027] In the above embodiment, the locking band may be sewn to the outer surface of the glove, in which case a portion of it will be left floating to form a connecting portion. Furthermore, the friction member of the locking device does not necessarily have to be a roller body as in the above embodiment. Alternatively, instead of a locking device, a locking mechanism that locks when a large load is applied and unlocks when the load is relieved or reduced may be used, or a locking mechanism that allows selection between a locked state and an unlocked state. It is not always necessary to use both left and right gloves; you can use only one glove if you wish. Furthermore, the use of gloves is not limited to rope climbing. [Explanation of Symbols]
