It is pulled by the metal fitting 38.

On the other hand, the fixing plate 36 can be removed from the constituent piece 20 by moving the metal fitting 38 in a direction away from the fixing plate 36. When the support pole 11 is contracted in this state, the ring 39 comes out of the support pole 11, so that the hook 40 can be removed from the ring 39. Therefore, it is possible to prevent the wire rod 29 and the wire rod 41 from being entangled with each other. The weight 30, the ring 39 and the hook 40 are located inside the support pole 11 between the guide 34 and the fixing plate 36. The wire 41 is arranged inside the support pole 11 over the hole 37, and the weight 42 is located outside the support pole 11.

FIG. 2 is a conceptual diagram corresponding to a state in which the support pole 11 is most extended in the direction along the center line A1. Therefore, in FIG. 2, the ratio of the length of each component piece in the direction along the center line A1 to the outer diameter of each component piece is practically different from the selected ratio. Specifically, the length of each component piece in the direction along the center line A1 is expressed in a significantly shorter ratio with respect to the length of the diameter of the component piece for convenience.

As shown in FIGS. 2 and 3, a wire rod 31 that suppresses bending of the support pole 11 is provided. The wire rod 31 is a flexible rope, wire, cable or the like, and the material of the wire rod 31 may be any of cotton thread, synthetic resin, metal and the like. A plurality of wire rods 31, for example, three as shown in FIG. 4 are provided. The first end of the three wires 31 is connected to and fixed to the constituent piece 15, and the second end of the three wires is independently connected to, that is, fixed to the three legs 12. .. The component piece 15 is located between the component piece 14 and the component piece 20 in the direction along the center line A1. The three wire rods 31 are all the same length, the three wire rods 31 are stretched with a predetermined tension, and the three wire rods 31 are not bent.

Further, as shown in FIG. 2, in addition to the three wire rods 31, it is also possible to provide the other three wire rods 32. The first end portions of the three wire rods 32 are connected to and fixed to the constituent pieces 19. That is, in the direction along the center line A1, the constituent piece 15 to which the first ends of the three wires 31 are connected and the constituent piece 19 to which the first ends of the three wires 32 are connected are different. .. The second end portion of the three wire rods 32 is independently connected and fixed to the three leg portions 12, respectively. The three wire rods 32 are all the same in length. The length of the three wires 32 is shorter than the length of the three wires 31. The three wire rods 32 are stretched with a predetermined tension, and the three wire rods 32 are not bent.

When the photographing assist device 10 of the present disclosure is installed at a use point 33 at a construction site, an event venue, or the like, the end portion of the leg portion 12 comes into contact with the use point 33. The place of use 33 may be any of the ground, concrete, asphalt, stairs, iron plate and the like. With the support pole 11 extended, the height H1 from the upper surface of the used portion 33 to the upper end of the constituent piece 14 can be set within the range of 800 cm to 1,100 cm.

As shown in FIG. 3, when the support pole 11 is contracted, the height H2 from the lower end of the constituent piece 20 to the upper end of the constituent piece 14 can be set within the range of 150 cm to 170 cm. The heights H1 and H2 are each determined by the number of the plurality of constituent pieces, the length of the plurality of constituent pieces along the center line A1, and the like. The height H1 is set depending on the application of the photographing assisting device 10, the surrounding conditions, and the like. The leg portion 12 and the support pole 11 are held in an upright state by the operator supporting the leg portion 12 by hand or fixing the leg portion 12 to the ground by an anchor or the like.

When the photographing assist device 10 of the present disclosure is installed at the place of use 33, the support pole 11 is erected in the direction along the vertical line. That is, the center line A1 is arranged in the direction along the vertical line. The vertical line is a virtual line that indicates the direction of action of gravity. Further, the weight 42 is not in contact with the used portion 33, and the weights 30 and 42 are suspended from the constituent pieces 14 in the air. Further, the weights 30 and 42 are not in contact with the support pole 11. Specifically, the weights 30 and 42 are separated from all the constituent pieces. The mass of the weight 42 is applied to the weight 30 via the wire 41, the hook 40, and the ring 39. Therefore, a load corresponding to the mass of the weights 30 and 42 is applied to the support pole 11. That is, the compressive load is applied to the support pole 11 in the direction along the center line A1.

Therefore, it is possible to prevent the support pole 11 from bending due to the wind, that is, from rolling. If the rolling of the support pole 11 can be suppressed, it is possible to suppress deterioration of the quality of the image and the video image taken by the photographing device 22. Further, 42 is located below the constituent piece 20 provided at the lowermost part of the support pole 11 in the direction along the center line A1. Therefore, the center of gravity of the unit including the support pole 11 and the mounting portion 13 can be set as downward as possible in the direction along the center line A1. Therefore, the support pole 11 is more stable.

Further, the battery 23 is provided between the mounting portion 13 and the constituent piece 20 in the direction along the center line A1. Therefore, the center of gravity of the unit including the support pole 11 and the mounting portion 13 can be set as downward as possible in the direction along the center line A1. Therefore, the support pole 11 is more stable. Further, when the weight 30 is fixed to the wire rod 29, it is possible to prevent the weight 30 from coming off the wire rod 29. Further, it is possible to prevent the weight 30 from falling off or separating in a strong wind.

Further, the guide 34 has a tubular shape. The guide 34 is made of metal or synthetic resin, and the wire rod 29 is passed through the hole 35 of the guide 34. The guide 34 comes into contact with the wire 29 when the wire 29 swings with the constituent piece 14 as a fulcrum. Therefore, it is possible to restrict the wire rod 29 from moving in the radial direction of the support pole 11, and it is possible to prevent the weight 30 from coming into contact with the inner surface of the constituent piece 20. Further, it is possible to prevent the wire rod 29 from being entangled inside the support pole 11.

Further, since the three wire rods 31 are provided, it is possible to reliably suppress the support pole 11 from rolling. Further, in addition to the three wire rods 31, three wire rods 32 are provided, and the height at which the three wire rods 31 are connected to the support pole 11 and the three wire rods 32 are connected to the support pole 11. Different from height. That is, the support pole 11 is supported at two locations along the center line A1 in different directions. Therefore, it is possible to reliably suppress the support pole 11 from rolling. Further, by adjusting the position of the metal fitting 38 in the length direction of the wire rod 41, the position of the weight 42 in the length direction of the wire rod 41 can be adjusted. Therefore, it is possible to prevent the weight 42 from coming into contact with the used portion 33.

Further, as shown in FIG. 3, the length of the wire rod 29 is set so that the wire rod 29 and the weight 30 can all be accommodated inside the support pole 11 when the support pole 11 is contracted. Further, when the support pole 11 is contracted, the fixing plate 36 is removed from the constituent piece 20, the hook 40 is removed from the ring 39, and the wire rod 41 and the weight 42 are removed from the support pole 11. Therefore, it is possible to prevent the wire rod 29 from being entangled inside the support pole 11.
