  The present embodiment is a transfer device including a moving body that carries and moves a transfer target, and a moving body support structure that supports and moves the moving body. The moving body support structure is characterized in that a portion corresponding to a ridge line of a structure or a portion corresponding to a valley bottom is provided as a trajectory of the moving body. Hereinafter, “lower” refers to the direction of gravity, ie, the vertical direction, and “up” refers to the opposite side of the direction of gravity, ie, the opposite side in the vertical direction.

  FIG. 1 is an overall view of a ferris wheel that is an example of a transport device according to the present embodiment. The right side of FIG. 1 is a front view of the ferris wheel 100, and the left side of FIG. 1 is a side view of the ferris wheel 100. In this ferris wheel 100, a frame 1 that is a moving body support structure is supported on the ground GL by a plurality of columns 2. As shown in FIG. 1, the frame 1 is an annular structure and is inclined with respect to a straight line (vertical line) LV indicating a vertical direction.

  A rail 3 that supports and moves a cabin 4 that is a moving body is attached to the frame 1. Two rails 3 are provided along the circumferential direction of the annular frame 1. The rails arranged on the outer side in the circumferential direction of the annular frame 1, that is, on the outer side in the turning direction of the cabin 4 are referred to as outer rails 3 o, and the rails arranged on the inner side in the circumferential direction, that is, on the inner side in the turning direction of the cabin 4. Both the outer rail 3o and the inner rail 3i are annular rails, and make a round along the circumferential direction of the annular frame 1. The track LM of the cabin 4 is formed between the outer rail 3o and the inner rail 3i.

  The frame 1 supports a plurality of cabins 4 through a rail 3 so as to be movable. The plurality of cabins 4 move in the direction of arrow R in FIG. The plurality of cabins 4 move on the rail 3 with a predetermined interval. While the cabin 4 of the ferris wheel 100 according to the present embodiment moves on the rail 3 and goes around the frame 1 in the circumferential direction, the floor 4F of the cabin 4 has a horizontal plane, that is, a plane perpendicular to the vertical direction. It is always kept approximately parallel. Next, a structure for holding the floor 4F substantially parallel to the horizontal plane will be described.

  FIG. 2 is a front view showing a cabin provided in the ferris wheel according to the present embodiment. FIG. 3 is a side view showing a cabin provided in the ferris wheel according to the present embodiment. The cabin 4 includes a cylindrical cabin 4 and cabin support frames 5 a and 5 b that support the cabin 4. The cabin support frames 5a and 5b are annular structures, and the cylindrical cabin 4 is disposed on the inner periphery of the cabin support frames 5a and 5b.

  A bearing 12 is provided between the cabin support frames 5 a and 5 b and the cabin 4, and the cabin support frames 5 a and 5 b support the cabin 4 via the bearing 12. As a result, the cabin 4 is supported so as to be pivotable in the directions of arrows r1 and r2 in FIG. Here, the cabin support frame 5a is arranged on the outer side in the circumferential direction of the frame 1 shown in FIG. 1, and the cabin support frame 5b is arranged on the inner side in the circumferential direction of the frame 1 shown in FIG.

  Brackets 6o and 6i are attached to the cabin support frames 5a and 5b, respectively. The brackets 6o and 6i attach the two wheels 7a and 7b holding the rail 3 to the cabin support frames 5a and 5b. As a result, the cabin support frames 5a and 5b are attached to the outer rail 3o and the inner rail 3i by the two wheels 7a and 7b and the brackets 6o and 6i that sandwich the rail 3, respectively. The cabin 4 moves along the rail 3, that is, the outer rail 3o and the inner rail 3i.

  The bracket 6o is arranged on the outer side in the circumferential direction of the frame 1 shown in FIG. 1, and the bracket 6i is arranged on the inner side in the circumferential direction of the frame 1 shown in FIG. The bracket 6o and the bracket 6i are connected by a beam 5B. Further, drive chain attachment members 8o and 8i are attached to the respective brackets 6o and 6i. The drive chain attachment members 8o and 8i connect the drive chains 9o and 9i to the cabin 4.

  As shown in FIGS. 1 and 2, the ferris wheel 100 according to the present embodiment includes a plurality of cabins 4. The drive chains 9o and 9i shown in FIGS. 2 and 3 connect the plurality of cabins 4 and mesh with the power transmission sprocket 11s. The power transmission sprocket 11s is driven by transmitting power through a power transmission chain 13 from a sprocket 10s attached to the output shaft of the electric motor 10 serving as a cabin driving means. As a result, the power generated by the electric motor 10 is transmitted to the drive chains 9o, 9i. With such a configuration, all the cabins 4 included in the ferris wheel 100 shown in FIGS. 1 and 2 move along the rails 3 in the circumferential direction of the frame 1.

  As described above, the cabin 4 is supported by the cabin support frames 5a and 5b so as to be rotatable about the cabin axis Z. Further, the cabin 4 of the cabin 4 has a larger mass on the floor 4F. As a result, when the cabin 4 moves along the rail 3, even if the cabin 4 is inclined with respect to the traveling direction of the cabin 4 (the direction of the arrow R in FIG. 3), the cabin 4 is centered around the cabin axis Z. The inside of the support frames 5a and 5b is rotated (directions of arrows R1 and R2 in FIG. 3). With such a structure, even if the cabin 4 is inclined with respect to the traveling direction R, the floor 4F is oriented in the vertical direction, so that the floor 4F of the cabin 4 is kept parallel to the horizontal plane.

  The cabin 4 provided in the ferris wheel 100 according to the present embodiment maintains the parallelism between the horizontal plane and the floor 4F using the gravity g. However, the cabin driving means for rotating the cabin 4 around the cabin axis Z is provided. The cabin driving means may be controlled so that the inclination of the floor 4F with respect to the horizontal plane is constant. In this way, the cabin 4 can be reliably rotated around the cabin axis Z, so that the parallelism between the floor 4F and the horizontal plane can be reliably maintained.

  With the above configuration, even if the cabin 4 is inclined with respect to the traveling direction R, the floor 4F of the cabin 4 is kept parallel to the horizontal plane. However, when the cabin axis Z shown in FIGS. 2 and 3 is inclined with respect to the horizontal plane, the floor 4F of the cabin 4 is also inclined with respect to the horizontal plane. Therefore, in the ferris wheel 100 according to the present embodiment, the floor 4F of the cabin 4 and the horizontal plane are maintained in parallel when the cabin axis Z is inclined with respect to the horizontal plane by the method described below.

  4, 5, 6-1, and 6-2 are conceptual diagrams for explaining a technique for maintaining the cabin floor parallel to the horizontal plane. In the present embodiment, a virtual structure 1V as shown in FIGS. 4 and 5 is considered. The virtual structure 1V is an annular virtual structure configured by stacking circles 1VCR, and is configured to imitate the frame 1 of the ferris wheel 100 shown in FIGS. Therefore, the virtual structure 1V has a circular cross-sectional shape orthogonal to the direction in which the circles 1VCR are stacked. That is, the circle 1VCR is a cross section of the virtual structure 1V.

  Here, a straight line orthogonal to the vertical direction (the direction of arrow g in FIGS. 4 and 6-1) is considered. This straight line is LC1 or LC2 shown in FIG. Since the straight lines LC1 and LC2 are orthogonal to the vertical direction, they are parallel to a plane orthogonal to the vertical direction, that is, a horizontal plane (corresponding to the ground surface GL in the present embodiment).

  A cross-section of the virtual structure 1V, that is, a contact point where the outer periphery of the circle 1VCR is in contact with the straight line LC1 orthogonal to the vertical direction is P1, and the lower side of the outer periphery of the circle 1VCR is a straight line LC2 orthogonal to the vertical direction. Let P2 be the contact point that contacts. The cabin provided in the cabin 4 shown in FIGS. 2 and 3 at the outer peripheral portion of the cross section of the virtual structure 1V, that is, the outer peripheral portion of the circle 1VCR, and the contact P1 or P2 contacting the straight line LC1 or LC2 perpendicular to the vertical direction. The axis Z and the straight line LC1 or LC2 orthogonal to the vertical direction are parallel to each other. Accordingly, since the cabin axis Z and the horizontal plane are parallel to each other at the contact point P1 or P2 on the outer peripheral portion of the circle 1VCR, the floor 4F and the horizontal plane of the cabin 4 are parallel to each other. Become parallel. That is, by rotating the floor 4F of the cabin 4 about the cabin axis Z, the floor 4F can be made parallel to the horizontal plane.

  Since the virtual structure 1V has a circular cross section, there are contacts P1 and P2 in contact with a straight line perpendicular to the vertical direction in all cross sections. Therefore, the line connecting the contacts P1 or P2 in all the cross sections of the virtual structure 1V (that is, all the circles 1VCR constituting the virtual structure 1V) is defined as the track LM or the track LM_a on which the cabin 4 moves. For example, while the cabin 4 is moving, the cabin axis Z and the horizontal plane are maintained in parallel. Thereby, during the movement of the cabin 4, the floor 4F rotates around the cabin axis Z, so that the floor 4F of the cabin 4 is parallel to the horizontal plane.

  With such a configuration, in order to keep the floor 4F of the cabin 4 parallel to the horizontal plane, the cabin 4 may be rotated around one axis. That is, since the cabin 4 only needs to be rotated around the cabin axis Z, the conventional rotation around the two axes is unnecessary in order to keep the floor 4F of the cabin 4 parallel to the horizontal plane. As a result, it is possible to maintain the parallelism between the floor 4F of the cabin 4 and the horizontal plane during the movement of the cabin 4 with a simple configuration.

  Further, as shown in FIG. 1, in the ferris wheel 100 according to the present embodiment, the position of the end of the cabin 4 in the cabin axis Z direction is switched between the 6 o'clock position and the 12 position. As a result, the view from the cabin 4 becomes surprising.

  Here, the track LM shown in FIG. 5 is obtained by connecting the contacts P1 to each other, and the track LM_a is obtained by connecting the contacts P2 with each other. Since the contact point P1 exists above the contact point P2, the track LM exists above the track LM_a. The frame 1 included in the ferris wheel 100 illustrated in FIGS. 1 and 2 may include at least one of the track LM and the track LM_a. For example, if both the track LM and the track LM_a are provided in the frame 1 shown in FIGS. 1 and 2, the number of cabins 4 mounted on the ferris wheel 100 can be increased. can do.

  The track LM is obtained by connecting the highest portions of the cross section of the virtual structure 1V, that is, the circle 1VCR constituting the virtual structure 1V. On the other hand, the trajectory LM_a is obtained by connecting the lowest part of the cross section of the virtual structure 1V, that is, the circle 1VCR constituting the virtual structure 1V. Thus, the trajectory LM becomes the ridgeline of the virtual structure 1V, and the trajectory LM_a becomes the valley bottom of the virtual structure 1V.

  In the above description, the trajectory for moving the cabin 4 is set using the virtual structure 1V, but the trajectory for moving the cabin 4 may be set using the circle 1VCR existing in the space. As shown in FIG. 6B, the contact point between the upper periphery of the plurality of circles 1VCR arranged in space and the straight line LC1 orthogonal to the vertical direction is P1, the lower periphery of the circle 1VCR, and the vertical direction A contact point where the straight line LC2 orthogonal to the contact point is defined as P2. At the contact P1 or P2 that contacts the outer periphery of the circle 1VCR and a straight line orthogonal to the vertical direction, the cabin axis Z provided in the cabin 4 shown in FIGS. 2 and 3 and the straight line LC1 orthogonal to the vertical direction or LC2 becomes parallel. Therefore, since the cabin axis Z and the horizontal plane are parallel to each other at the contact point P1 or P2 on the outer peripheral portion of the circle 1VCR, the floor 4F of the cabin 4 and the horizontal plane are parallel to each other.

  7 to 9 are explanatory diagrams illustrating an example of a method for correcting the cabin inclination. In the present embodiment, as shown in FIG. 7, the trajectory LM of the cabin 4 is not orthogonal to the cross section of the virtual structure 1V, that is, the circle 1VCR constituting the virtual structure 1V. This means that the trajectory LM of the cabin 4 is not orthogonal to the straight line LC1 that is in contact with the outer peripheral portion of the cross section of the virtual structure 1V, that is, the outer peripheral portion of the circle 1VCR, and orthogonal to the vertical direction. Accordingly, the outer rail 3o and the inner rail 3i that are provided on both sides of the track LM and support the cabin 4 are not orthogonal to the cross section of the virtual structure 1V, that is, the circle 1VCR that forms the virtual structure 1V.

  FIG. 8 shows a state in which the cabin 4 is at the 9 o'clock position of the watch in the ferris wheel shown in FIG. When the angle formed between the track LM of the cabin 4 and the straight line LC1 that is in contact with the outer periphery of the cross section of the virtual structure 1V and orthogonal to the vertical direction is α, the cabin 4 is a watch in the ferris wheel shown in FIG. 9 o'clock or 3 o'clock, the inclination angle (cabin axis inclination angle) between the cabin axis Z and the horizontal plane C is (90−α ′). Here, the units of α and α ′ are degrees, and since the virtual structure 1V is inclined in the three-dimensional space, α ≠ α ′. In two dimensions, the cabin shaft inclination angle is (90−α).

  Thus, if the trajectory LM of the cabin 4 is not orthogonal to the cross section of the virtual structure 1V, the cabin axis Z is inclined with respect to the horizontal plane C as in the attitude of the cabin 4 indicated by the solid line D in FIG. There are things to do. Therefore, the cabin shaft inclination angle 90-α ′ is set to 0 as much as possible, and the attitude of the cabin 4 is indicated by a dotted line E in FIG. 8 regardless of the position of the cabin 4 in the ferris wheel 100 shown in FIG. It is preferable to do so.

  In the ferris wheel 100 shown in FIG. 1, in order to set the cabin shaft inclination angle 90-α ′ to 0 regardless of the position of the cabin 4, in the present embodiment, the height and the inside of the outer rail 3o that supports the cabin 4 are set. Adjust the height of the rail 3i. This method will be described with reference to FIG. FIG. 9 shows a cross section perpendicular to the track LM of the cabin 4 in the ferris wheel shown in FIG. 1, and shows a state where the cabin 4 is at the 9 o'clock position of the timepiece. The outer rail 3o and the inner rail 3i are attached to the outer peripheral portion 1o of the frame 1. Further, the outer rail 3o and the inner rail 3i are arranged on both sides of the track LM. That is, the track LM of the cabin 4 is disposed between the outer rail 3o and the inner rail 3i. The horizontal distance between the outer rail 3o is Do, and the horizontal distance between the track LM and the inner rail 3i is Di.

  As shown in FIG. 7, the trajectory LM of the cabin 4 and the straight line LC1 orthogonal to the vertical direction are inclined by an angle α ′, and as shown in FIG. 8, at a cabin shaft inclination angle 90-α ′. In some cases, the cabin shaft inclination angle 90-α ′ is set to zero. As shown in FIG. 8, at the 9 o'clock position of the ferris wheel 100, the outside OUT of the cabin 4 is lower than the inside IN. Therefore, the height of the outer rail 3o is made larger than the height of the inner rail 3i so that the cabin shaft inclination angle 90-α ′ becomes zero. The vertical distance between the outer rail 3o and the track LM of the cabin 4 is Δh1, and the vertical distance between the inner rail 3i and the track 4 LM of the cabin 4 is Δh2. The height of the track LM of the cabin 4 is defined as the track height h0, and the case where it is higher than the track height h0 is defined as +, and the case where it is lower is defined as-.

  When the cabin shaft inclination angle 90-α ′ is set to 0, for example, as shown in FIG. 9, the vertical distance Δh1 between the outer rail 3o and the track LM of the cabin 4 is Do × sin (90-α ′), and the inner side A vertical distance Δh2 between the rail 3i and the track LM of the cabin 4 is set to Di × sin (90−α ′). Considering the track height h0 as the center, the height of the outer rail 3o is h0 + Δh1, and the height of the inner rail 3i is h0−Δh2. In this case, the difference between the height of the outer rail 3o and the height of the inner rail 3i is Δh1 − (− Δh2) = Δh1 + Δh2. As a result, the height of the outer rail 3o and the height of the inner rail 3i are different between the outer side in the turning direction of the cabin 4 and the inner side in the turning direction. More specifically, the height of the outer rail 3o is higher than the height of the inner rail 3i. Thus, the cabin shaft inclination angle 90-α ′ can be made zero by adjusting the height of the outer rail 3o and the height of the inner rail 3i.

  Note that the above method is merely an example, and in the ferris wheel 100 illustrated in FIG. 1, the method of setting the cabin shaft inclination angle 90-α ′ to 0 regardless of the position of the cabin 4 is not limited to the above method. Absent. For example, when the cabin 4 is supported by a single rail, the cabin shaft inclination angle 90-α ′ may be set to 0 by rotating the rail around the track LM of the cabin 4. Further, the cabin axis inclination angle 90-α 'may be set to 0 by correcting the set track 4 of the cabin 4 itself. Furthermore, the cabin shaft inclination angle 90-α ′ may be set to 0 by combining the method of adjusting the height of the rail and the method of correcting the set track 4 of the cabin 4 itself.

  FIG. 10 is a front view illustrating a modified example of the transport device according to the present embodiment. FIG. 11 is a side view illustrating a modified example of the transport device according to the present embodiment. 10 and 11 show only some of the cabins 4. The transfer device according to this modification is a ferris wheel, but the frame shape is different from that of the ferris wheel 100 described above. In the ferris wheel 100a shown in FIGS. 10 and 11, the shape of the frame 1a when viewed from the front is a substantially 8-character shape, that is, a shape in which alphabets O are connected. The frame 1a is supported on the ground GL by a plurality of support columns 2.

  The trajectory LM of the cabin 4 is set by the method described above. For example, consider a virtual structure formed by stacking circles 1VCR in the shape of the frame 1a, and the ridgeline or valley bottom of this virtual structure is defined as the track LM of the cabin 4. Further, the trajectory LM of the cabin 4 may be a trajectory connecting the contact points between the outer peripheral portion of the circle 1VCR and a straight line orthogonal to the vertical direction between the plurality of circles 1VCR arranged in the shape of the frame 1a. When the cabin 4 moves in the direction of the arrow R in FIG. 10 on the track LM of the cabin 4 provided on the frame 1a, the cabin axis Z and the horizontal plane are moved. Parallelism is maintained. As a result, the parallelism between the floor 4F of the cabin 4 and the horizontal plane is maintained.

  In addition, as shown in FIG. 1, the ferris wheel 100 a according to the present embodiment has the position of the end of the cabin 4 in the cabin axis Z direction at the position of the cabin F, the position G, and the position H. Change. As a result, the view from the cabin 4 becomes surprising. In addition, the ferris wheel 100a has an approximately 8-shaped frame 1a viewed from the front, and has an unexpected appearance, so that the presence thereof stands out.

  In the ferris wheel, if the cabin 4 moves on the track LM of the cabin 4 set by the above-described method, the cabin axis Z and the horizontal plane are maintained in parallel while the cabin 4 is moving. For this reason, the shape of the ferris wheel frame is not limited to the inclined annular frame 1 shown in FIG. 1 or the substantially 8-shaped frame 1a shown in FIG. In the present embodiment and the modification thereof, the ferris wheel is described as an example of the transport device, but the transport device is not limited to the ferris wheel.

  As described above, in the present embodiment, in the virtual structure having a circular cross section, the trajectory connecting the outer periphery of the cross section and the straight line orthogonal to the vertical direction is the trajectory of the moving body that conveys a person or an object. To do. Alternatively, a plurality of circles are arranged in the space, and a trajectory connecting the contact points between the outer peripheral portion of the circle and a straight line perpendicular to the vertical direction is defined as a trajectory of the moving body. Alternatively, in a virtual structure having a circular cross section, a portion corresponding to a ridge line of the virtual structure or a portion corresponding to a valley bottom is set as a trajectory of the moving body. Thereby, with a simple configuration, the floor of the moving body and the horizontal plane can be maintained in parallel regardless of the position of the moving body.

  Moreover, in the Ferris wheel, a passenger standing on the floor of the cabin is put into practical use. In such a cabin, it is important that the floor and the horizontal plane are parallel. The transport device according to the present embodiment can maintain parallelism between the floor of the moving body and the horizontal plane regardless of the position of the moving body with a simple configuration. It is effective for the device.

  As described above, the transport device according to the present invention is useful for a device that carries and moves a transport target such as a person or an object, and in particular, maintains the parallelism between the floor on which the transport target is mounted and a horizontal plane. Is suitable.
