[Figure 12] FIG. 11 is a front view showing a fourth example of use. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] The present invention will be described in detail below based on the illustrated embodiments. FIG. 1 shows an example (use example 1) of a usage state of an embodiment of the present invention. The present invention is a rope drive device Z that drives an endless looped rope 2 to circulate for suspending a number of objects (for example, carp streamers C shown in FIG. 1 and lighting equipment E shown in FIG. 11) at a predetermined interval P. In the example shown in FIG. 1, the endless looped rope 2, which is stretched in a meandering shape in a horizontal plane above a river R, is driven to circulate by the rope drive device Z. In FIG. 1, 17 is a guide roller for changing the direction of the rope. A number of object suspension parts 1 are arranged on the rope 2 at a predetermined interval P. Carp streamers C are suspended from the object suspension parts 1 of the rope 2 (sequentially, or at intervals of one or several), and the rope 2 is sequentially reeled out by the rope drive device Z. The predetermined interval P may be unequal.

[0013] As shown in Figs. 2 to 4, the rope drive device Z includes a vertically long base frame 3. A drive drum 4 on which the rope 2 is pulled and wound is disposed in the upper half of the base frame 3. A driven drum 5 on which the rope 2 is wound and paid out is disposed in the lower half of the base frame 3. The drive drum 4 and driven drum 5 each have a plurality of outer peripheral grooves 14, and are configured so that the endless looped rope 2 is wound in a cross-body shape (figure 8 shape) (see Fig. 3). For example, the rope is wound 3 to 7 times.

[0014] Furthermore, a drive motor 7 is disposed below one side plate 6 of the base frame 3, and a reducer 8 is disposed above one side plate 6, so that the rotational torque of the drive motor 7 is transmitted to the drive drum 4 via the reducer 8. The drive motor 7 is a motor that can be used with a portable small generator (not shown). In other words, a small generator that generates 100V, which is widely used on farms and in ordinary homes, is sufficient. The drive motor 7 is disposed on one side plate 6 of the base frame 3 with its lower portion protruding downward from the lower end 15 of the base frame 3.

[0015] A guide roller 13, around which the endless looped rope 2 is suspended, is provided in a position above the drive drum 4 in the base frame 3. The guide roller 13 is attached so as to be freely rotatable around the bolt member 22, and can be attached interchangeably to one end side (see FIG. 2) and the other end side (see FIG. 5) in the axial direction by changing the orientation of the bolt member 22 and the collar (cylinder) 23.

[0016] As shown in Figs. 6 and 7, the base frame 3 has a vertical groove surface 9 that is pressed against a vertical rod-shaped body T such as a tree trunk, bamboo, or a pillar (e.g., a utility pole, a farm shed pillar, a fence post, or a stake) protruding from the ground. The cross-sectional shape of the groove surface 9 is generally V-shaped, generally arc-shaped, or the like. The base frame 3 has through-holes 11 at each corner 10 on both sides of the groove surface 9. A fastening member 12 such as a belt is inserted through the through-holes 11 and wound around the vertical rod-shaped body T, so that the groove surface 9 of the base frame 3 is pressed against the vertical rod-shaped body T, and the base frame 3 is fastened to the vertical rod-shaped body T. Moreover, a vertical round bar 16 for preventing the belt from being damaged is fixed near the through-holes 11. It is preferable to use a load-tightening device (not shown) when fastening the base frame 3.

[0017] The height dimension H (see Fig. 2) of the base frame 3 is set to 1.6 to 3 times the front-to-rear width dimension W (see Fig. 4). If the height dimension H is less than 1.6 times the front-to-rear width dimension W, the drive drum 4 and driven drum 5 will be too close to each other, making it impossible to properly suspend the rope 2. If the height dimension H is more than 3 times the front-to-rear width dimension W, the distance between the drive drum 4 and driven drum 5 will be too large, and the vertical length dimension (height) will be unnecessarily large, making installation and use difficult.

[0018] FIG. 8 shows another embodiment of the present invention, in which the vertical round bar 16 is omitted.

[0019] 9 and 10 show another example (Use Example 2) of the present invention. An endless looped rope 2 stretched in a zigzag pattern in a horizontal plane above the river R is driven to rotate by a rope drive device Z. A horizontal guide roller attachment member 19 is attached to a vertical column 18, and a guide roller 17 is rotatably attached to the tip of the guide roller attachment member 19. A horizontal tensile force is applied to the rope 2 by a winch 20 as a tensioner to prevent slack in the rope 2. The other configurations are the same as those of Use Example 1 (shown in FIG. 1). In order to interrupt or end the display (due to bad weather, etc.) after the carp streamers C have been displayed in a hanging state for a predetermined period of time, the drive motor 7 is rotated in the reverse direction to pull the rope 2 toward the rope drive device Z, and the carp streamers C are removed one by one.

[0020] Fig. 11 shows yet another example of usage (Usage Example 3). A lighting device E such as an LED light, a lantern, or a light bulb is hung from the article hanging part 1 of the rope 2. The other configurations are the same as those of Usage Example 2 (shown in Fig. 10).

[0021] 12 shows a usage example 4. Inside the carp streamer C, a lighting device E such as a strip-shaped LED light is provided. The other configurations are the same as those of the usage example 2.

[0022] The present invention is open to design modifications, and for example, the article hanging portion 1 may be omitted. In other words, the hanging cord 30 of the carp streamer C (see Figs. 10 and 12) may be tied to the rope 2 or attached with a metal fitting.

[0023] As described above, the present invention relates to a rope drive device for driving an endless looped rope 2 for successively suspending a number of articles at a predetermined interval P in a circular motion, the rope drive device comprising a vertically long base frame 3, a drive drum 4 around which the rope 2 is pulled and wound, disposed in the upper half of the base frame 3, and a driven drum 5 around which the rope 2 is wound and paid out, disposed in the lower half of the base frame 3, a drive motor 7 disposed below one side plate 6 of the base frame 3, and a reducer 8 disposed above one side plate 6, so that the rotational torque of the drive motor 7 is transmitted to the drive drum 4 via the reducer 8, and the base frame 3 is provided with a vertical concave groove surface 9 which is pressed against a vertical rod-like object T such as a tree trunk, bamboo, or pillar protruding from the ground, thereby making the rope drive device easy to move, install, and use. In particular, since the installation area of ​​the device is extremely small, it is easy to install, use and move in forests, bamboo groves, etc. Furthermore, as long as there is the vertical rod T, it can be installed and used even in places where it is difficult to install the device, such as places with many unevenness or rocks or muddy ground.

[0024] Furthermore, the entire device (rope drive device Z) can be easily and reliably fixed in a stable vertical position relative to the vertical rod-shaped body T. Also, since the drive drum 4 is located in the upper half, the suspended object is pulled in smoothly without touching the ground or the like. Also, even if the rope 2 comes into contact with the ground or the like when being unwound from the driven drum 5, it can be unwound without any problems (because the rope 2 is light and slippery). Also, although the drive motor 7 is heavy, it is disposed in a lower portion of the base frame 3, so the entire device maintains a stable position. Also, the groove surface 9 is strongly pressed against the vertical rod-shaped body T, so that the entire device can be firmly fixed so that it does not shake--it does not sway when viewed from the horizontal front-to-rear direction (front).

[0025] Furthermore, since a large number of article suspending parts 1 are arranged on the rope 2 at the predetermined intervals P, articles can be reliably suspended at predetermined positions.

[0026] In addition, the base frame 3 has a through-hole portion 11 at each corner 10 on both side ends of the groove surface 9, and a fastening member 12 such as a belt is inserted through the through-hole portion 11 and wound around the vertical rod-shaped body T, so that the groove surface 9 of the base frame 3 is pressed against the vertical rod-shaped body T, thereby fastening the base frame 3 to the vertical rod-shaped body T. Therefore, by inserting the fastening member 12 through the through-hole portion 11, the base frame 3 can be easily and quickly fastened in a stable position.

[0027] In addition, a guide roller 13 on which the endless circular rope 2 is suspended is provided above the drive drum 4 on the base frame 3, so that the rope 2 can be pulled in and guided (guided) to an appropriate position on the drive drum 4.

[0028] In addition, the driving drum 4 and the driven drum 5 each have a plurality of outer peripheral grooves 14 and are configured so that the endless circular rope 2 is wound in a cross-hitch shape, so that the frictional force between the driving drum 4 and the driven drum 5 and the rope 2 is increased, preventing the rope 2 from slipping. Thus, the driving force is reliably transmitted, and the rope 2 can be smoothly pulled in and paid out.

[0029] In addition, the drive motor 7 is arranged on one side plate 6 of the base frame 3 with its lower portion protruding downward from the lower end 15 of the base frame 3. Although the drive motor 7 is heavy, by positioning it at a lower position, the entire device maintains a stable posture relative to the vertical rod-shaped body T.

[0030] In addition, since the drive motor 7 is a motor compatible with a small portable generator, this device can be used in forests and bamboo groves deep in the mountains, or in inconvenient locations (where no power lines are laid), etc. In particular, a small 100V generator that is widely used in farms and ordinary homes is sufficient.

[0031] Furthermore, since a vertical round bar 16 for preventing damage to the belt is fixed near the through hole 11, accidents such as damage to or cutting of the fastening member 12 such as a belt can be reliably prevented.

[0032] Moreover, since the height dimension H of the base frame 3 is set to 1.6 to 3 times the front-to-rear width dimension W, the drive drum 4 and the driven drum 5 can be arranged at an appropriate interval above and below, and the rope 2 can be appropriately suspended. Also, the installation and use are easy.

[0033] Furthermore, by hanging a large number of carp streamers C from the rope 2, the carp streamers C can be displayed on sunny days and taken down on rainy or stormy days easily and quickly. Conventional manual work to display and take down carp streamers C requires many people and is difficult, but this method solves these problems. In particular, trees such as those lining the banks of rivers R can be used as vertical rods T to carry out the work easily and reliably.

[0034] Furthermore, by suspending a number of lighting fixtures E from the rope 2, the lighting fixtures E can be turned on at night, and when necessary, can be removed from the article suspension part 1. In particular, by using a pillar or the like as the vertical rod-shaped body T, these operations can be easily performed. [Explanation of symbols]
