As shown in FIGS. 1, 2, and 8, one of the pair of pole bodies 11a and 11b in a lying posture accommodated in the storage box 3 in a substantially horizontal position, for example, the pole body 11a is attached to the handle 27a. 9 and 10, with the support shaft 32a as a fulcrum, as shown in FIG. 9 and FIG. 10, it is turned approximately 90 degrees counterclockwise to stand upright. As a result, the support shaft 32a rotates counterclockwise together with the pole body 11a, and the large-diameter gear 34a rotates approximately 90 degrees counterclockwise together with the support shaft 32a, so that the connecting plate 42 is in the state shown in FIG. 9 to move to the right side while slightly rotating as shown in FIG. 9, resulting in a substantially horizontal posture as shown in FIG. Thereby, the rotational force of the large-diameter gear 34a is transmitted to the large-diameter gear 34b via the attachment shaft 36a, the connecting plate 42, and the attachment shaft 36b, and the support shaft 32b rotates in the clockwise direction together with the large-diameter gear 34b. Then, the pole body 11b is rotated in the clockwise direction to be in an upright posture in association with the pole body 11a.

  When the large diameter gear 34a rotates in the counterclockwise direction, the small diameter gear 37a rotates in the clockwise direction, and the small diameter gear 38a rotates in the counterclockwise direction. Then, the rotary shaft 40a rotates in the clockwise direction together with the small diameter gear 39a, thereby rotating the rotating plate 41a, the connecting shaft 53a, and the rotating plate 51a in the clockwise direction. Then, the rotation of the rotation plate 51a causes the pulley 47a to rotate in the clockwise direction together with the rotation shaft 49a.

  The rotational force of the pulley 47a is transmitted to the pulley 65a via the belt 64a, and the rotating shaft 67a rotates together with the pulley 65a. As a result, the rotating plate 68a, the connecting shaft 71a, and the rotating plate 66a are rotated by approximately 90 degrees in the clockwise direction to the posture shown in FIG.

As described above, the pole main body 11b rotates in the clockwise direction in conjunction with the pole main body 11a and takes an upright posture so as to stand substantially vertically. Therefore, the large-diameter gear 34b fixed to the support shaft 32b is in the clockwise direction. Rotate to. As a result, the small diameter gear 37b rotates in the counterclockwise direction, and the small diameter gear 38b rotates in the clockwise direction.
Then, the rotating shaft 40b rotates in the counterclockwise direction together with the small diameter gear 39b, whereby the rotating plate 41b, the connecting shaft 53b, and the rotating plate 51b rotate. By rotation of the rotation plate 51b, the pulley 47b rotates in the counterclockwise direction together with the rotation shaft 49b.

The rotational force of the pulley 47b is transmitted to the pulley 65b via the belt 64b, and the rotating shaft 67b rotates together with the pulley 65b. As a result, the rotating plate 68b, the connecting shaft 71b, and the rotating plate 66b rotate approximately 90 degrees in the counterclockwise direction.
Since the large diameter gear 33a and the large diameter gear 33b are engaged with each other, the rotation plates 41a, 51a, 66a, and 68a rotate in the clockwise direction and the rotation plates 41b, 51b, 66b, and 68b counterclockwise. The rotation in the rotating direction is performed in synchronization.

By the rotation of the rotation plates 41a, 51a, 66a, 68a in the clockwise direction, the push-up plate 73a rises while rotating in the clockwise direction. Further, as the rotation plates 41b, 51b, 66b, and 68b rotate in the counterclockwise direction, the push-up plate 73b rises while rotating in the counterclockwise direction. Then, the lid body 57 is raised by the push-up plates 73a and 73b, and the lid body 57 is moved to a position where the upper opening 5 of the storage box 3 is closed. At this time, since the slidable contact pin 59 is slidably contacted with the guide rail 56, the lid body 57 is lifted while maintaining the horizontal posture, and the state shown in FIGS. 4, 11, and 12 is obtained.
Since the notches 12a and 12b are formed in the base end portions of the pair of pole bodies 11a and 11b, the left and right end portions of the lid 57 can escape from contacting the pole bodies 11a and 11b.

  When the pair of pole bodies 11a and 11b is switched from the standing posture to the lying posture, one of the pole bodies 11a and 11b, for example, the pole body 11a is put on the hand, and the support shaft 32a is used as a fulcrum. As shown in FIG. 4, the body is rotated approximately 90 degrees in the clockwise direction so as to be in a lying posture accommodated in the storage box 3 in a substantially horizontal posture. At this time, the support shaft 32a rotates in the clockwise direction together with the pole body 11a, and the large-diameter gear 34a rotates approximately 90 degrees in the clockwise direction together with the support shaft 32a. The rotational force of the large diameter gear 34a is transmitted to the large diameter gear 34b via the connecting plate 42, and the support shaft 32b rotates in the counterclockwise direction together with the large diameter gear 34b. As a result, the pole body 11b rotates counterclockwise, and becomes a lying posture accommodated in the storage box 3 in a substantially horizontal posture in conjunction with the pole body 11a.

  When the pole bodies 11a and 11b are switched from the standing posture to the lying posture, the large-diameter gear 34a rotates in the clockwise direction together with the support shaft 32a. When the large diameter gear 34a rotates in the clockwise direction, the small diameter gear 37a rotates in the counterclockwise direction, and the small diameter gear 38a rotates in the clockwise direction. Then, the rotary shaft 40a rotates in the counterclockwise direction together with the small diameter gear 39a, thereby rotating the rotating plate 41a, the connecting shaft 53a, and the rotating plate 51a. By rotation of the rotation plate 51a, the pulley 47a rotates in the counterclockwise direction together with the rotation shaft 49a.

  The rotational force of the pulley 47a is transmitted to the pulley 65a via the belt 64a, and the rotating shaft 67a rotates together with the pulley 65a. As a result, the rotation plate 68a, the connecting shaft 71a, and the rotation plate 66a rotate approximately 90 degrees in the counterclockwise direction.

  When the pole body 11a is rotated in the clockwise direction, this turning force is transmitted to the pole body 11b through the connecting plate 42 and is rotated in the counterclockwise direction to be in a lying posture. As the pole body 11b rotates in the counterclockwise direction, the large-diameter gear 34b fixed to the support shaft 32b rotates in the counterclockwise direction. As a result, the small diameter gear 37b rotates in the clockwise direction and the small diameter gear 38b rotates in the counterclockwise direction. Then, the rotating shaft 40b rotates in the clockwise direction together with the small diameter gear 39b, and the rotating plate 41b, the connecting shaft 53b, and the rotating plate 51b rotate in the clockwise direction. As the rotating plate 51b rotates, the pulley 47b rotates in the clockwise direction together with the rotating shaft 49b.

The rotational force of the pulley 47b is transmitted to the pulley 65b via the belt 64b, and the rotating shaft 67b rotates in the clockwise direction together with the pulley 65b. As a result, the rotation plate 68b, the connecting shaft 71b, and the rotation plate 66b rotate approximately 90 degrees in the clockwise direction.
Since the large-diameter gear 33a and the large-diameter gear 33b mesh with each other, the rotation plates 41a, 51a, 66a, and 68a rotate in the counterclockwise direction, and the rotation plates 41b, 51b, 66b, and 68b operate in the clockwise direction. The rotation in the rotating direction is performed in synchronization.

By the rotation of the rotation plates 41a, 51a, 66a, 68a in the counterclockwise direction, the push-up plate 73a is lowered while rotating in the counterclockwise direction. Further, as the rotation plates 41b, 51b, 66b, and 68b rotate in the clockwise direction, the push-up plate 73b descends while rotating in the clockwise direction. As a result, the cover 57 is lowered in the push-up plates 73a and 73b, and the upper surface opening 5 of the storage box 3 is opened. At this time, since the slidable contact pin 59 is slidably contacted with the guide rail 56, the lid body 57 is lowered while maintaining the horizontal posture. Then, the pair of pole bodies 11 a and 11 b close the upper opening 5 of the storage box 3.
In the above operation, the pole body 11a is switched to the standing posture and the lying posture while the pole body 11b is switched to the standing posture and the lying posture by placing the hand on the pole body 11b. Switch between standing posture and lying posture.

As described above, in the movable pole 1, one of the pair of pole bodies 11 a and 11 b is switched so as to be in a lying posture or a standing posture in which the storage box 3 is accommodated in a substantially horizontal posture. This can be done easily and quickly.
