As shown in FIG. 1, in the structure of the lifting and lowering and moving device (X) for a hanging rope, a rope holder (1; 1a, 1b)
Are provided at two upper and lower levels, a climbing rope (R) is inserted into the main body, and slidably attached in one direction (usually ascending direction) in a locked state.

Here, regarding the rope holder (1),
A well-known metal fitting [for example, 78 LOLIP (registered trademark) manufactured by Fujii Electric Works, Ltd.] can be used.

The support rods (5; 5a, 5b) are formed in a cane shape and project downward from the rope holders (1a, 1b) with different lengths and different lengths. In addition, each support rod (5a, 5b)
Is rotatably and variably fixed at a connection end between the rope holder (1) and a later-described balance rod (6).
Note that the difference in length is equivalent to the distance between the fulcrums of the balance rod-shaped body (6), and is a stepping allowance.

As shown in FIG. 3, the guide rod (2) is bridged between bracket pieces (3, 3) rotatably provided at one end of each rope holder (1a, 1b). . Here, the mounting structure of the guide rod (2) has a fixed end with respect to the lower rope holder (1b), and has an appropriate length with respect to the upper rope holder (1a) at the other end. Along with playing,
The spring members (4, 4) are mounted vertically above and below the bracket piece (3) on the loose insertion side (the upper rope holder (1a)). The spring members (4, 4) are col springs, and it is preferable to insert the col springs on the guide rods (2) so as to be freely movable. Note that a lock nut is provided at the free insertion end (free end) of the guide rod (2).

With this arrangement, it is possible to adjust the distance between the rope holders (1a, 1b) at a suitable interval when descending, and to stop and fix the position of the upper rope holder (1a) at the approach limit point. it can.

That is, when the rope holders (1a, 1b) interfere (collide) with each other at the time of descent, the locking (position fixing) function may be inoperable. A limit point is set, and when the upper rope holder (1a) reaches this position, it is automatically (forced) stopped to secure the anchor to the climbing rope.
It should be noted that the guide rod (2) does not need to function at all during the ascent. Of course, it does not hinder operation or operation.

The balance rod-shaped body (6) is rotatably supported at two points on one end of each of the support rods (5a, 5b), and has a stepping lock (7; 7a, 7b) at both ends. doing. In a preferred embodiment,
The stepping locks (7; 7a, 7b) are formed in a stirrup shape, and are suspended from both ends of the balance rod-shaped body (6) so as to be rotatable. The position of the foot stop (7; 7a, 7b) must be outside the fulcrum.

As shown in FIG. 2, the device user (H)
Rope holders (1a, 1b) are attached to the climbing rope (R) in two stages, and the lock levers (symbols omitted) attached to each rope holder (1a, 1b) are operated to fix the position. . That is, in the locked state, it is slidable (free) in the ascending direction and not slidable (locked) in the descending direction. Then, both feet are hung on the foot locking members (7a, 7b) to take a moving posture.

In the case of climbing (upward movement), the device user (H) holds one of the feet (in the illustrated embodiment, the stepping locking tool) while the upper and lower rope holding tools (1a, 1b) remain locked. (7
b)], the balance rod-like body (6) performs a seesaw operation via the fulcrum (6b) on the stepping side, the support rod (5a) on the floating foot side is pushed up, and the rope holder (1) is lifted.
a) slides up.

Next, the user of the apparatus (H) shifts his / her weight from this posture to the floating foot side. At this time, a load is applied to the rope holder (1a) on the floating foot side (upper row), and the position is fixed because the lock is in effect. Thus, by stepping in the opposite direction, the balance rod-shaped body (6) performs a seesaw operation via the alternated fulcrum (6a) on the stepping side, and the alternated supporting rod (5b) on the floating foot is pushed up, and , The rope holder (1b) slides up.

By repeating this stepping operation, the lower rope holder (1b) can follow the upper rope holder (1a) to increase the altitude on the climbing rope (R).

In the case of a cage (downward movement), the locks of the upper and lower rope holders (1a, 1b) are released as shown in FIG. . At this time, when the upper rope holder (1a) reaches the approach limit point (position) restricted by the guide rod (2), the upper rope holder is changed by stepping on while the lock is released. A load is applied to the support rod (5a) via the lock lever of (1a), and the support rod (5a) is naturally locked (position fixed), and the same operation and effect as in the locked state occurs.

Therefore, the foot lock (7a) for transmitting the force to the upper rope holder (1a) by the device user (H).
Weight bar and squeezing it into a bar (6)
Moves on the seesaw via the fulcrum (6a) on the stepping side, the support bar (5b) on the floating foot side is pushed down, and the rope holder (1b) slides down.

Next, when the device user (H) moves his weight from this position to the floating foot side, the upper rope holder (1a) slides again to the approach limit point regulated by the guide rod (2). It descends and is locked (position fixed) as described above. During this time, the balance rod-shaped body (6) performs a seesaw operation via the alternated fulcrum (6b) on the stepping side, and the alternated support bar (5b) on the floating foot is pushed down.

By repeating this stepping operation, the height of the climbing rope (R) can be lowered while the upper rope holder (1a) follows the lower rope holder (1b).

As described above, by hanging both feet on the stepping hooks (7; 7a, 7b) and performing the stepping operation while alternating the fulcrums (6a, 6b) of the balance rod-like body (6), the balance rod-like shape is obtained. The body (6) can be operated as a seesaw, and the rope holders (1; 1a, 1b) can be moved up and down by being driven in one direction, up or down.

Here, the device user (H) may select or mount an appropriate one of known safety devices (including safety belts) listed in the prior art to prevent a fall. Of course there are. This is because the climbing rope (R) is simulated as a vertical rope for working at heights.
