Different from the strap 20. As shown in FIG. 12, the main body case 33 of the camera 23 is provided with a mounting surface 34 composed of a convex spherical surface and a concave spherical surface on which the convex spherical surface 12 and the concave spherical surface 13 of the cylindrical piece 10 can be pressed, Openings 35 are provided at the centers of the two spherical surfaces of the mounting surface 34. The connecting string 15 passes through the opening 35 and is connected inside the main body case 33, and maintains a predetermined tension. As shown in FIG. 13, the chain-connected cylindrical pieces 10 can be appropriately deformed and formed to be used as a camera holding device that fixes the posture of the camera 23.

  Next, another embodiment according to the present invention will be described. As shown in FIG. 14, the camera strap 40 is provided with an adjusting device 41 for adjusting the tension of the connecting string 15 on the camera strap 20.

  As shown in FIG. 15, in the adjusting device 41, a lock button 43 and a compression spring 44 are inserted into a cylindrical case 42 with a bottom, and the bottom surface 43 a of the lock button 43 is constantly pressed by the compression spring 44. is recieving. The lock button 43 is provided with a lock hole 45 in the vicinity of the bottom surface 43 a, and openings 46 and 47 are provided on the sliding wall of the case 42 so as to face each other. When the lock button 43 is pushed by the compression spring 44, the openings 46 and 47 are closed by the lock button 43. When the lock button 43 is pushed against the spring force of the compression spring 44, the lock hole 45 moves to connect the two openings 46 and 47. Here, one part of the connecting string 15 is inserted into the communicating openings 46 and 47 and the locking hole 45, and a retaining ball 48 is attached to the end of the inserted connecting string 15. Yes.

  When the camera strap 40 is used as a strap, the lock button 43 is pressed to cause the lock hole 45 and the two openings 46 and 47 to communicate with each other. Release the pressure. The lock button 43 fixes the connecting string 15 between the inner wall of the locking hole 45 and the openings 46 and 47 by the urging force of the compression spring 44. The connecting string 15 is slightly longer than the total length of the cylindrical pieces 10 connected in a chain, and the convex spherical surface 12 and the concave spherical surface 13 of the adjacent cylindrical pieces 10 are not pressed against each other. No. 10 maintains flexibility and does not cause a sense of incongruity in carrying the camera 23.

  Here, when used as a fixing device of the camera 23, the lock button 43 is released from the position where the ball 48 is pulled away from the opening 47. The lock button 43 is pinched and fixed in a state where the connecting string 15 is kept in tension. Since the connecting string 15 presses the convex spherical surface 12 and the concave spherical surface 13 of the adjacent cylindrical pieces 10 by tension to generate appropriate friction, the chain-connected cylindrical pieces 10 are formed into a predetermined shape. When done, its shape can be maintained.

  As shown in FIG. 16, the camera strap 50 is provided with an adjusting device 51 instead of the adjusting device 41.

  As shown in FIG. 17, the adjusting device 51 is provided with a cylindrical piece 10 connected in a chain manner at the bottom. A lock button 53 and a compression spring 44 are inserted into a cylindrical case 52 with a bottom, and the bottom surface 53 a of the lock button 53 is always subjected to a pressing force by the compression spring 44. The bottom surface 52a of the case 52 is provided with a mounting surface 52b composed of a convex spherical surface and a concave spherical surface so that the convex spherical surface 12 and the concave spherical surface 13 of the cylindrical piece 10 can be pressed against each other. An opening 54 is provided at each center. The connecting string 15 passes through the opening 54 and is fixed to an attachment portion 53 b provided on the bottom surface 53 a of the lock button 53.

  The connecting string 15 fixed to the attachment portion 53 b always maintains a predetermined tension by the compression spring 44. Thus, when the cylindrical pieces 10 connected in a chain form are formed as a camera fixing device, a frictional force for maintaining the shape is generated. Therefore, it may be difficult to shape depending on the forming shape. Therefore, the lock button 53 is pressed against the urging force of the compression spring 44. The connecting string 15 that has pulled the cylindrical piece 10 is loosened, and the pressure contact force between the convex spherical surface 12 and the concave spherical surface 13 of the adjacent cylindrical piece 10 becomes weak, and the shaping becomes easy. When the desired shape can be formed, the lock button 53 is released. The lock button 53 pulls the connecting string 15 and generates tension on the connecting string 15. As a result, the convex spherical surface 12 and the concave spherical surface 13 of the adjacent cylindrical pieces 10 are brought into pressure contact with each other to generate appropriate friction, so that the formed shape can be maintained. Further, when the adjusting device 51 is provided in this way, the elasticity of the connecting string 15 should be relatively small, and may not be present at all.

  Next, a modified example of the cylindrical piece will be described. As shown in FIG. 18, an L-shaped cylindrical L-shaped piece 60 is arranged between the cylindrical pieces 10 connected in a chain. For example, when the adjustment device 41 is adjusted and the connecting string 15 is in tension when used in the camera strap 40 described above, the L-shaped shape is maintained, which is convenient for L-shaped forming. When the tension of the connecting string 15 is loosened by the adjusting device 41, the cylindrical piece 10 and the L-shaped piece 60 can be linearly arranged as shown in FIG. There is little discomfort.

  Next, a modified example of the L-shaped piece will be described. As shown in FIG. 20, a convex piece 62 having a convex spherical surface 12 on one end side and a slope 61 of, for example, 45 ° on the other end side, and a slope 63 of the same angle on one end side and a concave on the other end side. A split L-shaped piece 65 is constituted by the concave piece 64 having the spherical surface 13. Grooves 66 and 67 are provided in the center of the slope 61 of the convex piece 62, and ribs 68 and 69 are provided in the center of the slope 63 of the concave piece 64.

  As shown in FIG. 21, when the groove 66 and the rib 68 are aligned with the inclined surface 61 and the inclined surface 63 so that the groove 67 and the rib 69 are fitted, the L-shaped piece 65 forms an L-shape, as shown in FIG. Thus, when the groove 66 and the rib 69 are combined with the inclined surface 61 and the inclined surface 63 so that the groove 67 and the rib 68 are fitted, the L-shaped piece 65 is not L-shaped but linear. Thus, there is no sense of incongruity when used as a strap.
