DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a three-dimensional bicycle parking lot for storing bicycles three-dimensionally.

[0002]

2. Description of the Related Art In recent years, with the increase in the use of bicycles, bicycles have been left behind in narrow open spaces in front of stations, causing pollution near stations. For this reason, construction of a large-scale bicycle parking lot in front of the station has been considered, and the number of actually constructed places is increasing. Such bicycle parking places include bicycles arranged in a plane,
There is a tower parking or the like in which the number of accommodation planes is increased by increasing the height while being arranged in a plane.

However, since it is difficult to secure such a large land in front of the station, it has been difficult to construct a bicycle parking lot. Further, since the storage method is a planar storage method, the area utilization efficiency is poor, and the number of stored bicycles is limited.

[0004] Therefore, in order to store a large number of bicycles in a small land, a three-dimensional bicycle parking lot in which bicycles are stored three-dimensionally is employed. The following are known as such a three-dimensional bicycle parking lot.

For example, as shown in FIG. 15, bearings are provided on the upper and lower portions of a three-dimensional structure 41 to support gears 42 and 43, and a chain 44 is linked to the gears 42 and 43.
Then, a plurality of shafts 45 are mounted on the chain 44 at predetermined intervals, and symmetrical arms 46 are mounted on both sides of the chain 44, respectively. At the lower end of the arm 46, a mounting table 47 for mounting the bicycle C is horizontally arranged. Then, the gears 42 and 43 are driven by a driving device (not shown) provided on the gears 42 and 43 to circulate the mounting table 47 in conjunction with the chain 44.

[0006]

Incidentally, the above-mentioned conventional three-dimensional bicycle parking lot accommodates bicycles in the height direction, so that the number of accommodated bicycles is larger than that of a planar bicycle parking lot. However, in the three-dimensional bicycle parking lot shown in FIG. 15, when the mounting table 47 is rotated by the gears 42 and 43, the mounting tables 47 are prevented from contacting the bicycles C mounted on the other mounting tables 47.
It was necessary to maintain a predetermined interval. Therefore, there is a problem that the dimension in the height direction of the three-dimensional structure 41 is increased.

In order to rotate the mounting table 47,
The diameter dimensions of the gears 42 and 43 must be sufficiently ensured. Therefore, as a result, there is a problem that the dimension in the depth direction of the three-dimensional bicycle parking lot becomes large.

The object of the present invention has been made in view of the above circumstances, and by reducing the distance between each rack pallet on which a bicycle is mounted, a large-scale land is not required and the construction can be made in a small space. It is to provide a possible three-dimensional bicycle parking lot.

(2) Operation and Effect Next, the operation of the above-described three-dimensional bicycle parking lot according to the present embodiment will be described with reference to FIGS. 1, 8 and 9. FIG. 8 shows a case where the rack pallet 1 moves on the upper rotating part R, and FIG. 9 shows a case where the rack pallet 1 moves on the lower rotating part R.
To move. In the present embodiment, it is assumed that the control device (not shown) manages the availability of the rack pallet 1 and the entry / exit of bicycles. That is, the control device manages data as to whether or not a bicycle is mounted on the rack of each rack pallet 1.
It is assumed that operation control of the drive wheel 6 and the tail wheel 7 is performed.

First, when the bicycle C arrives, when the user arrives at the gate 8, the user causes a card reader (not shown) to read a user card on which a personal number and the like are recorded. Thus, the control device selects and stores the rack in which the bicycle is to be stored, and drives the drive wheel 6 and the tail wheel 7 to move the rack pallet 1 in which the selected rack is present before the gate 8. Move.

Then, the user moves the bicycle C in the direction of arrow B and mounts it on the rack. At that time, bicycle C
Is moved on the guide groove 14 shown in FIG.
Fix with 5.

When leaving the bicycle C, the user causes the card reader to read the user card in the same manner as when entering the bicycle. Then, the control device moves the rack pallet 1 on which the rack in which the bicycle C of the user is stored exists to the gate 8.
Move before. As a result, the user moves the bicycle C in the direction of arrow B 'and takes it out of the rack.

Here, the operation of moving the rack pallet 1 will be described. When the control device drives the drive wheel 6 and the tail wheel 7 to move the conveyor chain 5, the truss arm 2 connected to the conveyor chain 5 by the rotating shaft 27 moves accordingly.

First, when the truss arm 2 moves on the vertical moving portion V, the rollers 24a and 24b attached to both ends of the arm portion 21 of the truss arm 2 move on the truss arm guide 3b. Further, along with this, the rack pallet 1 in which the main pillar 16 is connected to the tip of the support plate 25 of the truss arm 2 is pulled and moved by the truss arm 2.

On the other hand, when the truss arm 2 moves on the turning portion R, the rollers 24a and 24b move on the curve of the turning portion R while the truss arm 2 itself turns around the rotation shaft 27. . The truss arm 2 is a rack pallet 1
The rotation part R is rotated while being rotated by the rotation shaft 26 at the connection portion with the main pillar 16.

At this time, when moving the upper rotating portion R shown in FIG. 1, only the roller 18a above the main column 16 moves on the rack pallet guide 3a as shown in FIG. The roller 18b moves away from the rack pallet guide 3b. Then, when approaching the vertical movement part V again,
The lower roller 18b returns onto the rack pallet guide 3a.

When moving the lower rotating portion R shown in FIG. 1, the lower roller 18b is moved as shown in FIG.
Only the roller 18a moves on the rack pallet guide 3a, and the upper roller 18a moves away from the rack pallet guide 3b. Then, when approaching the vertical moving portion V again, the upper roller 18a returns onto the rack pallet guide 3a.

As described above, in the rotating portion R, of the rollers 18a and 18b of the main column 16 of the rack pallet 1, only the preceding roller moves on the rack pallet guide 3a,
The following roller moves away from the rack pallet guide 3a. Further, since the truss arm 2 is rotated by the rotation shaft 26 as described above, the main pillar 16 of the rack pallet 1
Regardless of the direction of the truss arm 2, a state perpendicular to the horizontal plane can be maintained. For this reason, the rack pallet 1 moves on the rotating portion R while its posture is maintained by the preceding roller.

Further, since the vertical posture of the main column 16 is maintained when the rotating portion R is rotated, the rack pallet 1
When the roller approaches the vertical moving portion V again, the following roller can return to the rack pallet guide 3a again.

According to the above-described configuration, the rack pallet 1 is not directly connected to the drive wheel 6 and the tail wheel 7 but is connected via the truss arm 2. Even if the diameter dimension of the rack pallet 1 is small, the turning radius of the rack pallet 1 can be increased.

Further, through the truss arm 2, the leading and trailing rack pallets 1
, The bicycles held on the rack pallet 1 do not come into contact with each other. Therefore, the height distance between the rack pallets 1 in the vertical moving section V can be reduced. Therefore, the height of the three-dimensional structure 4 can be reduced.

Also, as in the conventional three-dimensional bicycle parking lot shown in FIG.
According to the method in which the mounting table 47 is supported in conjunction with the mounting table 4, the moving speed of the mounting table 47 cannot be increased because the mounting table 47 may swing back and forth. On the other hand, according to the present embodiment, the rack pallet 1 includes two rollers 24a and 24b and two rotating shafts 2 in addition to the roller 18a in the rotating portion R.
6 and 27, and in the vertical movement part V, it is supported at six points of four rollers 18a, 18b, 24a and 24b and two rotating shafts 26 and 27, so that the Can always be stable. Therefore, rack pallet 1
Moving speed can be increased.

Further, as shown in FIG.
And the tail wheel 7 are arranged inside the rotating part R of the rack pallet guide 3a and the truss arm guide 3b, and as shown in FIG.
Since a is mounted inside the truss arm guides 3b, 3b, the trajectories of the rack pallet 1, the truss arm 2, and the conveyor chain 5 do not intersect.

On the other hand, when the drive arm 51 is moving in the direction of the arrow A ', the lower roller 58b supported up to that point is separated from the lower roller guide 60b, and the upper roller 58a is supported by the upper roller guide 59a. become. Therefore, at this position P4, the upper roller 58a and the lower roller 5
8b will be replaced.

Similarly, when the drive arm 51 is at the lowermost position (position P
9), the upper roller 58a and the lower roller 58
b is the upper roller guide 59a and the lower roller guide 60
b. That is, one of the upper roller 58a and the lower roller 58b that has been supported until then is separated from the upper roller guide 59b or the lower roller guide 60b, and the other roller is supported. Therefore, even at this position P9,
The support of the upper roller 38a and the lower roller 38b is exchanged.

(2) Operation and Effect Next, the operation of the above-described three-dimensional bicycle parking lot according to the present embodiment will be described with reference to FIG. Also in the present embodiment, it is assumed that the control device (not shown) manages the empty state of the rack pallet 1 and the entry / exit of bicycles, similarly to the first embodiment. In addition, it is assumed that the entry and exit of the bicycle are performed at the gate not shown in FIG.

Here, the movement operation of the rack pallet 1 will be described. When the control device drives the drive wheel 6 and the tail wheel 7 to move the drive chain 56, the drive chain 56 causes the chain side roller 5 to move.
3a and 53b are pulled, and the driving arm 51
Moves, and the rack pallet 1 moves.

Here, it is assumed that the rack pallet 1 at the position P1 moves in the direction of arrow A. At this time, the lower rollers 58b are moved until the rack pallet 1 reaches the position P2.
Only the roller moves along the lower roller guide 60a. That is, during this time, the upper roller 58a is in a state where it is not supported anywhere. Then, the rack pallet 1 further rises from the position P2, and the upper roller 58a moves to the section S1.
Then, the upper roller 58a comes to be supported by the upper roller guide 59a. Then, the lower roller 5
The upper roller 58a and the lower roller 58b move in a supported state until 8b passes the section S1.

Next, when the lower roller 58b passes the section S1, the lower roller guide 60a is eliminated and only the upper roller guide 59a is provided, so that only the upper roller 58a is supported. That is, the support of the lower roller 58b and the support of the upper roller 58a are switched.

With only the upper roller 58a supported, the rack pallet 1 passes through the position P3 and reaches the uppermost position, that is, the position P4. At this time, the lower roller 58b contacts the lower roller guide 60b while the upper roller 58a is supported by the upper roller guide 59a. Then, the upper roller 58a is
9a, only the lower roller 58b is supported. That is, the upper roller 58a and the lower roller 58b
The support is replaced.

Thereafter, the rack pallet 1 passes through the position P5, moves in the direction of arrow A, and reaches the position P6, whereupon the upper roller 58a is supported by the upper roller guide 59b. Then, when descending from the position P6, the lower roller 58b separates from the lower roller guide 60b, and only the upper roller 58b is supported.

Thereafter, the rack pallet 1 further descends,
After passing through the positions P7 and P8, the lowermost position, that is, the position P
Reach 9 Here, as in the case of the uppermost position P4 described above, the support of the upper roller 58a and the lower roller 58b is switched. Then, again, the lower roller 5
8b is supported.

Although the case where the rack pallet moves in the direction of arrow A has been described here, the upper roller 58a and the lower roller 58b also move in the direction of arrow A '.
Is similarly performed.

Here, in FIG. 10, the arrow D indicates the direction of each of the upper roller 58a and the lower roller 58b. That is, since the posture arms 52a and 52b rotate about the shaft 57 as a fulcrum,
8a and the direction in which the lower roller 58b moves
Direction. Since the posture arms 52a and 52b are joined at 90 degrees, the direction of the upper roller 58a and the lower roller 58b indicated by the arrow D is determined by the upper roller guide at any point of the rotating portion R and the vertical moving portion V. 59
a, 59b and the lower roller guides 60a, 60b are maintained at an angle of 45 degrees or more. Therefore, the upper roller 58a and the lower roller 58b correctly advance in the guide direction without being shaken or caught. For this reason, the attitude of the rack pallet 1 is always stable.

Also, except when the support of the upper roller 58a and the lower roller 58b in the positions P4 and P9 and the sections S1 and S2 is exchanged, only one of the upper roller 58a and the lower roller 58b is supported. The rack pallet 1 moves. Here, assuming that both the upper roller 58a and the lower roller 58b are always supported, the direction of each of the upper roller 58a and the lower roller 58b, the shaft 57 serving as a fulcrum, and the upper roller 58
The position of the guide must be set in consideration of the positional relationship between the three points a and the lower roller 58b. That is, in order for the upper roller 58a and the lower row 58b to always move correctly, it is necessary to strictly set the position of the guide. However, in the present embodiment, as described above, only one of the upper roller 58a and the lower roller 58b is supported, so that only the positional relationship between the shaft 57 and either one of the above-described rollers needs to be considered, and There is no need for strict positioning accuracy.

Further, at a position where the drive arm 51 is at an angle of 45 degrees with respect to the horizontal plane as at a position P8 shown in FIG. 10, the drive arm 51 and the posture arm 52b are aligned on the same straight line. When the drive arm 51 is moving in the direction of arrow A ', the lower roller guide 60a is extended as it is, and if the lower roller 58b advances along the lower roller guide 60a, the direction of the lower roller 58b is lower. The direction is almost the same as that of the roller guide 60a. Therefore, in order to prevent the posture of the rack pallet 1 from becoming unstable, the angle, position, and the like of the curved portion of the lower roller guide 60a must be strictly set. However, in the present embodiment, the lower roller guide 60a disappears before approaching the position P8.
Is separated from the lower roller guide 60a, and the other roller, that is, the upper roller 58a, is supported by the upper roller guide 59b. Therefore, there is no need to strictly set the position of the guide by aligning the drive arm 51 and the posture arm 52b on the same straight line.
