Description

The present invention relates to a bicycle parking machine.

In a bicycle parking machine having a rack that can be raised and lowered vertically, a bicycle is carried into the rack at the lower position of the column, and the rack in the actual vehicle state is stored and managed at the upper position. In Patent Document 1, the actual vehicle elevating drive unit for elevating and driving the rack in the actual vehicle state includes a double-acting air cylinder as an actuator for raising and lowering the actual vehicle, an air supply device including a switching valve, a pressure accumulator tank, and a pressure booster. It has a winding transmission mechanism including a pulley, a fixed pulley and a lifting rope, and at least an air cylinder and a winding transmission mechanism are arranged outside the column. Specifically, a moving pulley is connected to the tip of the piston rod of the air cylinder, one end of the elevating rope is fixed to a support column, the middle part is wound around the moving pulley and the fixed pulley, and then the other end. Is fixed to the lift that supports the rack. As a result, the piston stroke (for example, 0.6 m) of the air cylinder on the drive side is shortened to half of the rack stroke (for example, 1.2 m) on the actuating side.

On the other hand, in Patent Documents 2 and 3, as an actuator for raising and lowering an actual vehicle instead of a double-acting air cylinder, the push output of the piston when the gas sealed in the cylinder passes through the piston and moves from the rod side to the head side. A protruding gas spring is used as a drive source, and the cost is reduced by greatly simplifying the peripheral configuration. Further, the safety of the operator and the actual vehicle elevating drive unit is improved by arranging the entire actual vehicle elevating drive unit (that is, the gas spring and the winding transmission mechanism) inside the column.

By the way, in general, the main use of a gas spring is to support a light load (for example, to support the opening and closing of a hatchback door of an automobile), and it is used with a relatively short piston stroke (for example, within 0.3 m). On the other hand, as in Patent Documents 2 and 3, the gas spring is a relatively long actuator for raising and lowering the actual vehicle of the bicycle parking machine under the heavy load (for example, 20 to 40 kg weight) of the rack in the actual vehicle state. When used frequently and for a long period of time with a piston stroke (for example, 0.6 m or more), an O-ring is used to further improve durability, especially to maintain high airtightness and oiltightness of the piston. It is required to extend the life of sealing members such as oil seals.

At that time, by using a plurality of high-quality sealing members (multiple structure), it is possible to contribute to extending the life of the sealing member and improving the durability of the gas spring, but the effect of introducing the gas spring instead of the air cylinder (cost reduction) is lost. There is a risk of being damaged (offset). In addition, the durability of the gas spring can be improved by changing the design of the gas spring (for example, increasing the diameter and length of the cylinder), but safety is achieved because all or part of the actual vehicle elevating drive unit cannot be placed inside the column. May be hindered.

Japanese Unexamined Patent Publication No. 2007-138680 Japanese Unexamined Patent Publication No. 2018-039493 Japanese Patent No. 6598340

An object of the present invention is to impair the cost reduction effect associated with the introduction of the gas spring, which is an actuator for raising and lowering the actual vehicle, and the safety improving effect associated with the arrangement of the gas spring as the actual vehicle raising and lowering drive unit and the internal support of the winding transmission mechanism. Instead, it is intended to shorten the piston stroke of the gas spring for raising and lowering the actual vehicle, and to provide a bicycle parking machine that contributes to the miniaturization and improvement of the durability of the winding transmission mechanism and the bicycle parking machine as a whole.

Means for Solving Problems and Effects of Invention

In order to solve the above problems, the bicycle parking machine of the present invention is used.
A first drive unit (for example, an empty vehicle elevating drive unit) for raising and lowering an empty rack without a bicycle in a horizontal posture along a column erected in a tubular shape in the vertical direction, and an actual vehicle equipped with a bicycle. A bicycle parking machine including a second drive unit (for example, an actual vehicle elevating drive unit) for raising and lowering the rack in a state in a horizontal posture along the support column.
The second drive unit is a piston rod (that is, an actual vehicle) that projects downward from a cylinder (that is, an actual vehicle cylinder) of a gas spring for raising and lowering an actual vehicle to which a base end portion is attached inside the upper part of the column and exerts a traction force. Two moving pulleys (that is, actual vehicle moving pulleys) that are connected to the tip of the piston rod) and have a common rotation axis (that is, the actual vehicle rotation axis), and the inside of the column at a position higher than the cylinder. Two fixed pulleys (ie, real vehicle fixed pulleys) fixed in position and a single wire rope (ie, real vehicle) wound alternately around each of the moving pulleys and each of the fixed pulleys. It is characterized by having a winding transmission mechanism (that is, a winding transmission mechanism for an actual vehicle) in which a pulley (pulley) is incorporated.

Further, in order to solve the above problems, the bicycle parking machine of the present invention is used.
A first drive unit (for example, an empty vehicle) for swinging an empty rack without a bicycle between a horizontal posture at the lower part of a support column erected in a tubular shape in the vertical direction and an inverted posture along the support column. A bicycle parking machine including a swing drive unit) and a second drive unit (for example, an actual vehicle lift drive unit) for raising and lowering a rack in an actual vehicle state on which a bicycle is mounted in a horizontal posture along the support column.
The second drive portion is connected to the tip portion of a piston rod that projects downward from the cylinder of the actual vehicle elevating drive gas spring to which the base end portion is attached and exerts a traction force inside the upper part of the support column, and has a common rotation axis. Two moving pulleys, two fixed pulleys whose position is fixed inside the support column at a position higher than the cylinder, and one winding of each of the moving pulleys and each of the fixed pulleys alternately once. It is characterized by having a winding transmission mechanism incorporated with a single wire rope.

In this way, regardless of whether the rack is stored horizontally or inverted, it is connected to the tip of the piston rod of the gas spring for raising and lowering the actual vehicle and has a common rotation axis. By incorporating one moving pulley and two fixed pulleys whose positions are fixed inside the column into the winding transmission mechanism of the second drive unit, the actual vehicle drive stroke (1/4 of the rack stroke) is the limit. The piston stroke) can be shortened. That is, the moving distance of the sealing member (for example, O-ring) in the cylinder can be shortened to reach 1/4 (about 0.3 m) of the rack stroke (for example, about 1.2 m). The shortened amount is accumulated by repeated reciprocating movements, and the life of the sealing member is extended, and the durability of the gas spring for raising and lowering the actual vehicle and the entire bicycle parking machine is improved. In addition, the distance between each of the two moving pulleys and the fixed pulley is set to be equal to each other, and the two moving pulleys rotate around a common rotation axis. It can contribute to the miniaturization of the internal structure).

Moreover, at this time, since it is not necessary to replace the sealing member with a high-quality one or to use a plurality of sealing members, the cost reduction effect due to the introduction of the gas spring is not hindered. In addition, since it is not necessary to replace the gas spring for raising / lowering the actual vehicle with a large product or changing the arrangement position, the effect of improving safety by arranging the gas spring for raising / lowering the actual vehicle and the winding transmission mechanism inside the column is hindered. There is no such thing.

As described above, the "actual vehicle drive stroke" is equal to the "piston stroke of the gas spring for raising and lowering the actual vehicle", and is also synonymous with the "moving distance of the sealing member (for example, O-ring) in the cylinder".

By the way, in a bicycle parking machine having a vertical vertical elevating rack, the first drive unit functions as an empty vehicle elevating drive unit in a type that horizontally stores an empty rack, and a constant load spring for elevating drive as an actuator for elevating an empty vehicle. A gas spring or the like for driving an empty vehicle up and down is used. On the other hand, in the type in which the rack in the empty vehicle state is stored upside down, the first drive unit functions as an empty vehicle rocking drive unit, and as an actuator for empty vehicle rocking drive, a constant load spring for rocking drive, a gas spring for rocking empty vehicle, etc. Used.

For example, in the case of the horizontal storage type, when a moving pulley is also provided in the gas spring for raising and lowering an empty vehicle, it can be expressed as follows.
The first drive unit is an empty vehicle that projects downward from the empty vehicle cylinder of the empty vehicle elevating drive gas spring to which the base end is attached inside the upper part of the column separately from the actual vehicle elevating drive gas spring to exert traction force. Two empty pulleys that are connected to the tip of the piston rod and have a common rotation axis for empty vehicles, and two empty vehicles that are fixed inside the column at a position higher than the cylinder for empty vehicles. A winding transmission mechanism for an empty vehicle, which incorporates a fixed pulley, a moving pulley for each empty vehicle, and a single wire rope for empty vehicles that is alternately wound once for each fixed pulley for empty vehicles. Has.

By the way, in both the horizontal storage type and the inverted storage type, each moving pulley and an intermediate fixed pulley located between the two moving pulleys when the wire rope is wound among the two fixed pulleys. It is desirable that the pulley diameters are almost the same.

In this way, the piston stroke is reduced to nearly 1/4 of the rack stroke by forming the two moving pulleys that rotate around a common rotation axis and the intermediate fixed pulleys with almost the same pulley diameter. It is easy to improve the durability of the gas spring for raising and lowering the actual vehicle, and thus the entire bicycle parking machine. In addition, the difference in peripheral speed between the two moving pulleys and the intermediate fixed pulleys on which the wire rope is hung is reduced, vibration and noise are less likely to occur, uneven wear of each pulley is suppressed, and winding transmission is performed. It contributes to the improvement of the durability of the mechanism and the entire bicycle parking machine.

Then, in order to exert these effects, when the pulley diameter of the pulley having a medium size among the two moving pulleys and the intermediate fixed pulley is set to D, the pulley diameters of the other pulleys are 0.9D to 1 . It is desirable to belong to the range of 1D [D ± 0.1D] (for example, when the pulley diameter of the intermediate fixed pulley to be medium is D = 50 mm, the pulley diameter of each moving pulley is within the range of 45 to 55 mm). .. In the case of a sheave sheave having a groove for holding the wire rope, the "pulley diameter" corresponds to both the nominal diameter and the effective diameter.

As a more specific example, two moving pulleys and intermediate fixed pulleys are formed with the same pulley diameter, connected to the base end side of the cylinder on one end side of the wire rope, and attached to the tip end side of the piston rod. Starting from one of the moving pulleys, the intermediate fixed pulleys arranged on the base end side of the cylinder and the other moving pulleys arranged on the tip end side of the piston rod are alternately wound and continued. Further, when it is wound around the remaining fixed pulley (terminal fixed pulley described later) attached to the base end side of the cylinder and directly or indirectly connected to the rack on the other end side of the wire rope,
The number of suspended wire ropes for the two moving pulleys is 4, and the actual vehicle drive stroke (that is, the piston stroke) is about 1/4 of the rack stroke.

Further, the two moving pulleys are supported by a common moving pulley central shaft, and the intermediate fixed pulley is supported by an intermediate fixed pulley central shaft arranged in parallel with the moving pulley central shaft.

As a result, the second drive unit (gas spring for raising and lowering the actual vehicle and the winding transmission mechanism) can be accommodated in a small and compact space in the limited space inside the support of the bicycle parking machine, so that the safety of the operator and the second drive unit can be accommodated. The second drive unit operates smoothly, and vibration and noise are less likely to occur.

In addition, the central axis of the terminal fixed pulley that supports the terminal fixed pulley excluding the intermediate fixed pulley of the two fixed pulleys is arranged coaxially with the central axis of the intermediate fixed pulley.
The terminal pulley may have a larger pulley diameter than the intermediate pulley.

When the pulley diameter of the terminal fixed pulley is larger than that of the intermediate fixed pulley in this way, it is easy to take out the wire rope end portion from the terminal fixed pulley to the outside of the support column, so that the wire rope is mainly accommodated and arranged inside the support column. The rope work between the winding transmission mechanism and the rack side that is arranged so as to project outward from the column is simplified.

Further, the wire rope has a start end fixed inside the upper part of the column and an end connected to the rack.
An elevating bogie is provided that moves up and down inside the column while holding the two moving pulleys around which the middle part of the wire rope is wound at the tip of the piston rod.
The lift bogie may be provided with a guide wheel that travels along the inner wall of the column while rotating around the axis of rotation.

As a result, the lift bogie can be compactly housed in the column, and the piston rod's advance / retract (that is, extension / contraction) operation in the gas spring for raising / lowering the actual vehicle moves the lift bogie down / up (and eventually the rack goes up / down). It is transmitted smoothly and stably as a movement).

Starting from the moving pulley 28A in the form of being wound around the pulley 28A, the fixed pulley 24B (intermediate fixed pulley) arranged on the base end side of the cylinder 21S and the other movement arranged on the tip end side of the piston rod 21R. It continues to be wound alternately with the pulley 28C, and is further wound around the remaining fixed pulley 24D (terminal fixed pulley) attached to the base end side of the cylinder 21S.

Then, the other end 25B (termination) side of the wire rope 25 is directly or indirectly connected to the rack 13.

The fixing member 110 has a facing plate portion 111 (gas spring fixing facing plate portion) fixed to the support column 1 and a gas spring assembling shaft 112 extending between the facing plates. On the other hand, both of the gas springs 11GS and 21GS have assembling insertion portions 11T and 21T at the ends of the cylinders 11S and 21S opposite to the piston rods 11R and 21R, respectively. Further, both the gas springs 11GS and 21GS are attached to the support column 1 by inserting both the assembling insertion portions 11T and 21T into the assembling shaft 112 between the facing plate portions 111. At this time, the axis R112 of the assembly shaft 112 extends in the width direction of the support column 1, and the gas springs 11GS and 21GS are arranged in the support column 1 so as to be arranged at a predetermined interval in the width direction. It is possible to swing around the axis R112 (swing axis) in the support column 1.

Further, as shown in FIG. 9, in the gas springs 11GS and 21GS, the moving pulley fixing members 120 and 150 are fixed to the tip portions of the piston rods 11R and 21R, respectively. The moving pulley fixing members 120 and 150 have moving pulley fixing facing plate portions 121 and 151, and moving pulley central shafts 122 and 152 extending between the facing plates 121 and 151, respectively. The two moving pulleys 18A and 18C are supported so as to be inserted into a common moving pulley central shaft 122, and can rotate around the rotation axis R18, which is the axis thereof. On the other hand, the two moving pulleys 28A and 28C are also supported so as to be inserted into the common moving pulley central shaft 152, and can rotate around the rotation axis R28, which is the axis thereof.

Here, the support column 1 is provided with a front-rear partition wall portion 30 for partitioning a rear side where the upper carriage 12 and the lower carriage 22 move in the vertical direction and an internal front side where the elevator carriages 17 and 27 move up and down. The partition wall portion 35 for the elevating carriage is formed so as to project forward from the center in the width direction of the front and rear partition wall portions 30.

Further, as shown in FIGS. 8 and 11, the support column 1 also functions as a gas spring fixing member as an intermediate fixed pulley fixing member for assembling the intermediate fixed pulleys 14B and 24B inside the support column 1 as described above. It has a member 110. The intermediate fixed pulley fixing member and the gas spring fixing member may be provided separately.

The fixing member 110 has an intermediate fixed pulley central shaft 113 extending between the facing plates 111 (opposing plate for fixing the intermediate fixed pulley). The intermediate fixed pulley central shaft 113 is arranged in parallel with the above-mentioned moving pulley central shafts 122 and 152. Here, the intermediate fixed pulleys 14B and 24B are supported so as to be inserted into a common intermediate fixed pulley central shaft 113, and can rotate around the axis line R113. The intermediate fixed pulleys 14B and 24B and the intermediate fixed pulley central shaft 113 are arranged above the gas spring assembly shaft 112 inside the column 1.

Further, as shown in FIGS. 8 and 12, the support column 1 has terminal fixed pulley fixing members 130 and 140 for assembling the terminal fixed pulleys 14D and 24D inside. The terminal fixed pulley fixing members 130 and 140 include the terminal fixed pulley fixing facing plate portions 131 and 141 fixed to the support column 1 and the terminal fixed pulley central shafts 132 and 142 (see FIG. 12) extending between the facing plates. Each has. The terminal fixed pulleys 14D and 24D are supported so as to be inserted into the respective terminal fixed pulley central axes 132 and 142, and are rotatable around the respective axis lines R14 and R24 (see FIG. 12). As shown in FIG. 8, the terminal fixed pulley fixing members 130 and 140 here are arranged above the fixing member 110 inside the support column 1. Further, the terminal fixed pulley fixing members 130 and 140 here project from the upper end of the support column 1 and are housed in the upper cover 101 (see FIGS. 1 to 4) assembled to the upper end portion of the support column 1.

The terminal fixed pulley central shafts 132 and 142 are arranged non-parallel to the moving pulley central shafts 122 and 152, and the terminal fixed pulleys 14D and 24D are arranged in an "eight" shape in a plan view. Specifically, as shown in FIG. 12, one of the terminal fixed pulleys 14D and 24D (14D in this case) is located behind the other (24D in this case) in a plan view (upper side in FIG. 12). In addition, the center lines Y1 and Y2 in the width direction are arranged separately on the first side (left side in FIG. 12) and the second side (right side in FIG. 12), and the winding center lines Y1 and Y2 are the center lines in the width direction. It is arranged at an angle so as to intersect Y. When the wire rope 15 extends upward from the front side (lower side in FIG. 12) in the support column 1 and from the first side in the width direction (left side in FIG. 12) and is wound around the terminal fixed pulley 14D at the tip thereof, It extends downward from the intersection of the winding center line Y1 with the widthwise center line Y, passes behind the wire rope 25 (upper side in FIG. 12), reaches the upper bogie 12, and the terminal 15B is fixed to the upper bogie 12. (See FIG. 11). On the other hand, when the wire rope 25 extends upward from the front side (upper side in FIG. 12) in the support column 1 and from the second side in the width direction (right side in FIG. 12), and is wound around the terminal fixed pulley 24D at the tip thereof. , Extends downward from the intersection of the winding center line Y2 with the width direction center line Y, passes through the front side (lower side in FIG. 12) of the wire rope 15 to reach the lower bogie 22, and the terminal 25B is fixed to the lower bogie 22. (See FIG. 10).

As shown in FIGS. 5 to 7 (b), the winding transmission mechanisms 16 and 26 of this embodiment are arranged side by side in the width direction in the support column 1. Then, after the wire ropes 15 and 25 are turned back by the moving pulleys 18C and 28C, except for the fixed pulleys 14D and 24D and the trolleys 12 and 22, basically the first side in the width direction and the second vice versa. Arranged symmetrically with the side.

Specifically, the wire rope 15 is hooked and fixed to the empty car wire rope fixing portion 102 (see FIG. 11) provided at an upper position in the support column 1. The hooking position is a position biased toward the center side in the width direction of the first side in the width direction in the column 1. Then, the moving pulley 18A and the moving pulley 18C are arranged side by side in the outward direction from the hooking position toward the first side in the width direction. The intermediate fixed pulley 14B is arranged at the same position as the moving pulley 18A or the moving pulley 18C, or at a position between them in the outward direction. As a result, the wire rope 15 is wound around the pulleys 18A, 14B, and 18C in order from the central side in the width direction to the first side / outer direction in the width direction in the support column 1. Since the terminal fixed pulley 14D is arranged so as to be inclined with respect to the width direction center line Y as described above, the wire rope 15 is wound around the fixed pulley 14D from the first side in the width direction and has a width. Extends downward at the center of the direction.

On the other hand, the wire rope 25 is also hooked and fixed to the empty car wire rope fixing portion 102 (see FIG. 11) provided at an upper position in the support column 1. The hooking position is a position biased toward the center side in the width direction of the second side in the width direction in the column 1. Then, the moving pulley 28A and the moving pulley 28C are arranged side by side in the outward direction from the hooking position toward the second side in the width direction. The intermediate fixed pulley 24B is arranged at the same position as the moving pulley 28A or the moving pulley 28C, or at a position between them in the outward direction. Therefore, the wire rope 25 is also wound around the pulleys 28A, 24B, and 28C in order from the center side in the width direction in the support column 1 toward the second side outer direction in the width direction. Since the terminal fixed pulley 24D is arranged so as to be inclined with respect to the width direction center line Y as described above, the wire rope 25 is wound around the fixed pulley 24D from the second side in the width direction and has a width. Extends downward at the center of the direction. However, the center position of the wire rope 25 is also displaced in the front-rear direction from the wire rope 15 extending downward at the center position in the width direction, and is located in front of the wire rope 15 here.

Further, as shown in FIGS. 1 to 4, the bicycle parking machine 100 of the first embodiment includes a bogie lock mechanism 40 (lower stop mechanism) and a rack lock mechanism 50 (movement stop mechanism). As for the bogie lock mechanism 40 and the rack lock mechanism 50, since the same mechanism is described in Japanese Patent Application Laid-Open No. 2018-0349493, detailed description thereof will be omitted.

As shown in FIG. 2, the bogie lock mechanism 40 disengages both bogies 12 and 22 when the bicycle BCL is not carried into the rack 13 and is in a bogie lock operation state in which the lower bogie 22 cannot be raised or lowered. On the other hand, as shown in FIG. 3, when the bicycle BCL is carried into the rack 13, both bogies 12 and 22 are connected, and the lower bogie 22 is unlocked so that the lower bogie 22 can be raised and lowered.

Specifically, the bogie lock mechanism 40 engages (here, locks) the lower bogie 22 with the support column 1 when the lower bogie 22 is in a predetermined lower stage position and the rack 13 is in an empty state. Then, the lower bogie 22 is locked so as not to be able to move up and down (see FIG. 2). Then, when the upper bogie 12 descends with respect to the lower bogie 22 in this bogie lock operating state, it becomes a connectable state in which the upper bogie 12 is lined up in close proximity to each other. In conjunction with the detection operation, both bogies 12 and 22 are connected so as to be able to move up and down in an integrated state. Further, the bogie lock mechanism 40 disengages the lower bogie 22 with the support column 1 in conjunction with the connection operation, and unlocks the lower bogie 22 so that the lower bogie 22 can be raised and lowered (see FIG. 3). In this way, the bogie lock mechanism 40 acts as a lower bogie lock mechanism (second lift bogie lock mechanism) and a bogie connecting mechanism.

The means for detecting the empty state and the actual vehicle state of the rack 13 is a wheel receiver 44 that can swing back and forth on the rack 13 and is urged to a backward tilted state by a wheel receiving urging member (not shown) such as a spring member. (First detection means). When the wheel receiver 44 is in the backward tilted state (actual vehicle non-detection state), it is detected as an empty vehicle state, and when it is in the forward tilted state (actual vehicle detection state) by receiving the preceding carry-in wheel (for example, front wheel FW) of the bicycle BCL, it is the actual vehicle. Detect as a state. In conjunction with the operation of the wheel receiver 44, the bogie lock mechanism 40 switches between the bogie lock operation state and the bogie lock release state.

The rack lock mechanism 50 is in a rack lock operating state in which the rack 13 cannot move up and down with respect to the support column 1 when the rack 13 is in a predetermined lower position (see FIGS. 2 and 3) or a predetermined upper position (see FIGS. 1 and 4). On the other hand, the rack lock operating state is released based on the operation of the operating member 54 (second detecting means), and the predetermined lower position (see FIGS. 2 and 3) or the predetermined upper position (FIGS. 1 and 4) is released. It enables the rack 13 to move up and down with respect to the support column 1 in (see).

Specifically, in the rack lock mechanism 50, the rack 13 is in a predetermined lower position (see FIGS. 2 and 3) or a predetermined upper position (see FIGS. 1 and 4), and the operating member 54 is inactive. When in the state, the upper bogie 12 is engaged (locked here) with the support column 1 and locked so that the upper bogie 12 cannot be raised or lowered. When the operating state of the operating member 54 is detected in this rack lock operating state, the rack lock mechanism 50 disengages the upper trolley 12 with the support column 1 in conjunction with the detection operation, and the upper trolley 12 moves up and down. Unlock so that it is possible (rack unlocked state). In this way, the rack lock mechanism 50 acts as an upper bogie lock mechanism (first lift bogie lock mechanism).

The actuating member 54 is provided at the entrance / exit 13E of the carry-in bicycle BCL at the rear end of the rack 13, and is provided with an actuating member urging member (not shown) such as a spring member so that the tip end side (rear end side) is at an upper position. Be urged. When the tip end side (rear end side) of the actuating member 54 is in the upper position, it is in the non-operation state (operation non-detection state), and the tip end side (rear end side) is the wheel (front wheel FW or rear wheel RW) of the bicycle BCL. The operating state (operation detection state) is when the wheel is placed or pushed down to a lower position by an artificial operation.

As described above, the bogie lock mechanism 40 is a mechanism that locks and holds the lower bogie 22 at a predetermined lower stage position to prohibit the rack 13 from ascending, and the wheel receiver 44 receives the wheels and the lower bogie 22 becomes the upper bogie 12. The lock can be released when connected. On the other hand, the rack lock mechanism 50 is a mechanism that locks and holds the upper carriage 12 at predetermined lower and upper positions to prohibit the rack 13 from moving up and down, and the lock can be released by operating the operating member 54.

-The lower bogie 22 is in the lower position (moving pulleys 28A and 28C are in the upper position, and the piston rod 21R is in and out: Fig. 6).
-The lower bogie 22 can be raised by the bogie lock mechanism 40 (the wheel receiver 44 is switched to the forward tilted state).
・ Both bogies 12 and 22 are now connected.

<Rise of actual vehicle rack = Rise of actual vehicle rack: Fig. 3 → Fig. 4>
In the state of FIG. 3, when the operating member 54 is brought into the operating state by an artificial operation (for example, stepping on the operating member 54), the rack lock mechanism 50 switches the upper carriage 12 so as to be able to rise. Then, the rack 13 and both bogies 12 and 22 are pulled up to the position shown in FIG. 4 by using the urging force of the gas springs 11GS and 21GS. At this time, the piston rods 11R and 21R of the gas springs 11GS and 21GS protrude, and the moving pulleys 18A, 18C, 28A and 28C change their positions from top to bottom (FIG. 6 → 5). Since the urging force of the gas springs 11GS and 21GS is almost balanced with the total weight of the bicycle BCL, rack 13, and both bogies 12 and 22 (actually, it is set slightly larger than the total load), a slight force. The rack 13 can be pulled up with.

-The upper bogie 12 cannot be lowered by the rack lock mechanism 50 (the operating member 54 is not operated).
-The lower bogie 22 is in the upper position (moving pulleys 28A and 28C are in the lower position, and the piston rod 21R is protruding: FIG. 5).
-The lower bogie 22 can be lowered by the bogie lock mechanism 40 (the wheel receiver 44 maintains the forward leaning state).
・ Both bogies 12 and 22 remain connected.

<Actual vehicle rack descent = The actual vehicle rack descends: Fig. 4 → Fig. 3>
In the state of FIG. 4, the operating member 54 is brought into the operating state by an artificial operation, so that the rack lock mechanism 50 switches the upper carriage 12 so that it can be lowered. Then, the rack 13 and both bogies 12 and 22 are lowered to the position shown in FIG. 3 against the urging force of the gas springs 11GS and 21GS. At this time, the piston rods 11R and 21R of the gas springs 11GS and 21GS move in and out, and the moving pulleys 18A, 18C, 28A and 28C change their positions from bottom to top (FIG. 5 → 6). Since the urging force of the gas springs 11GS and 21GS is almost balanced with the total weight of the bicycle BCL, rack 13, and both bogies 12 and 22 (actually, it is set slightly larger than the total load), a slight force. The rack 13 can be pushed down with.

<Bicycle unloading = When the bicycle is unloaded from the rack, the empty rack automatically rises: Fig. 3 → Fig. 2 → Fig. 1>
When the bicycle BCL moves backward on the rack 13 in the state of FIG. 3, the front wheel FW (preceding carry-in wheel) separates from the wheel receiver 44 and returns to the forward leaning state. As a result, the lower bogie 22 is switched so as not to be ascended by the bogie lock mechanism 40.
Further, when the bicycle BCL moves backward on the rack 13 and the front wheel FW (preceding carry-in wheel) is placed on the operating member 54, the operating member 54 is pushed down to be in the operating state. As a result, the upper bogie 12 is switched so as to be able to rise by the rack lock mechanism 50. However, since the front wheel FW (preceding carry-in wheel) is mounted on the operating member 54, the upper bogie 12 cannot be raised due to its weight.
When the front wheel FW (preceding carry-in wheel) is separated from the operating member 54, the rack 13 and the upper bogie 12 are automatically raised by using the urging force of the gas spring 11GS. Since the urging force of the gas spring 11GS is almost in balance with the total weight of the rack 13 and the upper bogie 12 (actually, it is set slightly larger than the total load), the rack 13 is set to be slightly larger than the total load in FIG. It can be pushed up to the position. The lower bogie 22 is left at the lower position.

<Empty rack rise = Empty rack rises: Fig. 2 → Fig. 1>
In the state of FIG. 2, the upper trolley 12 cannot be raised by the rack lock mechanism 50, but the rack lock mechanism 50 raises the upper trolley 12 by setting the operating member 54 into the operating state by an artificial operation.

Finally, the terminal fixed pulley 24D, which is located at the same position in the width direction as the moving pulley 28C, is wound from the rear side to the front side, descends downward, and is fixed to the lower carriage 22. In this way, the wire rope 25 is wound so as to gradually change its position from the outside in the width direction to the center from the start end 25A to the end end 25B. Therefore, the operation of the pulleys 28A, 24B, 28C, and 24D is stable, and the wire rope 25 hanging from the terminal fixed pulley 24D on the rear side of the support column 1 is located at the center position in the width direction of the support column 1 (width direction center line Y). You can pass through the above) in a stable manner.

As described above, in the bicycle parking machine 100 of the second embodiment, the urging force of the constant load spring 11CS is used instead of the urging force of the gas spring 11GS acting on the rack 13 in the first embodiment. There is no difference. Therefore, the operation of the second embodiment is the same as that of the first embodiment, and the description thereof is omitted.

First, the actual vehicle elevating drive unit 20'will be described. The actual vehicle elevating drive unit 20'is a bogie 61 (elevating bogie) by the gas spring 21GS (actual vehicle elevating drive gas spring) and the constant load spring 11CS (actual vehicle elevating drive constant load spring 11CS) described in the second embodiment. It operates as a bogie lifting mechanism for raising and lowering. The reference numeral of the constant load spring for raising / lowering the actual vehicle in the third embodiment is 29CS. The bogie 61 is always urged to be pulled upward by a gas spring 21GS forming an actuator for raising and lowering the actual vehicle and a constant load spring 29CS for driving the actual vehicle up and down. Here, the actual vehicle elevating drive unit 20'acts so as to constantly pull up the bogie 61 with a traction force corresponding to the total load of the bogie 61, the rack 62 (provided with accessories such as the brace 63), and the rack-mounted bicycle BCL. ..

Further, the actual vehicle elevating drive unit 20'has a winding transmission mechanism 26 (actual vehicle trigger transmission mechanism). The winding transmission mechanism 26 exists as in the second embodiment. Therefore, also in the second embodiment, it is located between the respective moving pulleys 28A and 28C and the two moving pulleys 28A and 28C when the wire rope 25 of the two fixed pulleys 24B and 24D is wound. The intermediate fixed pulley 24B has the same pulley diameter (see FIGS. 18 and 19).

Further, the two moving pulleys 28A and 28C are supported by a common moving pulley central shaft 222 (see FIG. 19), and the intermediate fixed pulley 24B is an intermediate fixed pulley central shaft arranged in parallel with the moving pulley central shaft 222. Supported by 213 (see FIG. 20). The terminal fixed pulley central axis supporting the terminal fixed pulley 24D excluding the intermediate fixed pulley 24B among the two fixed pulleys 24B and 24D is arranged coaxially with the intermediate fixed pulley central axis (similar to the second embodiment). , The terminal fixed pulley central axis and the intermediate fixed pulley central axis are arranged as a common fixed pulley central axis 213: see FIG. 20), the terminal fixed pulley 24D has a pulley diameter larger than that of the intermediate fixed pulley 24B. There is.

Further, an elevating carriage 27 is provided which moves up and down inside the support column 1 while holding the two moving pulleys 28A and 28C around which the intermediate portion of the wire rope 25 is wound at the tip of the piston rod 21R. Is provided with a guide wheel 3 that travels along the inner wall of the support column 1 while rotating around the moving pulley rotation axis R28. That is, also in the third embodiment, the moving pulley rotation axis R28 also functions as a guide wheel rotation axis.

Since the configuration of the winding transmission mechanism 26 of the third embodiment is the same as that of the winding transmission mechanism 26 of the second embodiment, detailed description thereof will be omitted.

As described above, the actual vehicle elevating drive unit 20'of the third embodiment includes a main drive unit having the actual vehicle elevating drive gas spring 21GS and the winding transmission mechanism 26, and an auxiliary drive unit having c constant load spring 29CS. The gas spring 21GS always urges the same bogie 61 upward together with the actual vehicle elevating drive constant load spring 29CS.

The bogie 61 of the third embodiment is integrally assembled to the rack 62 so as to be able to move up and down, while a traction force is applied by the actual vehicle elevating drive unit 20'to a predetermined lower position with respect to the support column 1 (see FIGS. 23 and 24). ) And the predetermined upper position (see FIG. 25) so as to be able to move up and down by the roller 6. The carriage 61 here is also the same as the upper carriage 12 and the lower carriage 22 of the first and second embodiments, along the guide rail 34 provided on the rear side surface of the support column 1 as shown in FIGS. 10 and 11. Move up and down. The bogie 61 is in the lower position (see FIG. 23) together with the rack 62 when the piston rod 21R of the gas spring 21GS moves in and out (contracts), and is brought into the actual vehicle state by carrying in the bicycle BCL (see FIG. 24), while the piston rod 21R. The bicycle BCL is stored by ascending to the upper position together with the rack 62 due to the protrusion (extension) of the bicycle (see FIG. 25).

The empty vehicle rocking drive unit 10'is for realizing a function as an inverted storage of the rack 62, that is, an empty vehicle rocking drive unit for storing the rack 62 in an empty vehicle state in which the bicycle BCL is not mounted in an inverted state (see FIG. 22). It is provided with a rotary slider crank mechanism 60 and a rack rotation mechanism 70 (moment applying mechanism), which are basic configurations. The mechanism related to these is also described in Japanese Patent No. 6598341.

As shown in FIGS. 22 to 25, the rotary slider crank mechanism 60 includes a carriage 61 that functions as a fixed link, a rack 62 that functions as a rotary drive link, and a brace 63 (side guard) that functions as a rotary driven link. It is formed in the shape of a rigid body triangle. The bogie 61 functions as a fixed link in the rotary slider crank mechanism 60.

As shown in FIG. 23, the rack 62 is rotatably supported in the front-rear direction around a rotation shaft 620 (rotation axis C62) whose front end portion (base end portion) extends in the width direction with respect to the lower portion of the bogie 61. It extends in a cantilever shape in the shape of a gutter, and an entrance / exit 65 for carrying in / out the bicycle BCL is formed at the tip (rear end). A moment centered on the rotation shaft 620 is applied to the front end portion by the rack rotation mechanism 70 in an empty vehicle state, and the rack rotation mechanism 70 is rotatably arranged from a horizontal state to an inverted state along the support column 1 with respect to the trolley 61 at the lower stage position. The details will be described later), and the rotary slider crank mechanism 60 functions as a rotary drive link.

A pair of braces 63 are arranged on both sides of the rack 62 in the width direction, and one end portion (upper end portion in FIGS. 22 to 24) of the brace 63 is arranged with respect to the upper portion of the carriage 61 with respect to the swing axis 630 (swing axis C63) in the width direction. It is supported so that it can swing around. On the other hand, the other end of the pair of braces 63 (the lower end in FIGS. 22 to 24) is an elongated hole 621 (guide portion) formed in the middle of the rack 62 and closer to the rear end (tip). On the other hand, a slide pin 631 (slider) that is engaged and supported so as to be slidably movable in the empty vehicle state (see FIG. 22) at the lower stage is formed, and functions as a rotation driven link in the rotary slider crank mechanism 60.

As described above, the rotary slider crank mechanism 60 is configured such that the rack 62 and the brace 63 crank motion via the slide pin 631 (slider center C61). Specifically, the empty rack 62, the brace 63, and the bogie 61 shown in FIG. 23 are deployed in a right-angled triangular shape with the rack 62 substantially horizontal at the lower position of the support column 1, while the slide pins. As the 631 slides in the elongated hole 621 along the longitudinal direction of the rack, the rack 62 and the brace 63 rotate upward with respect to the carriage 61 and are stored in an inverted state along the support column 1. In this inverted state, the rack 62 is housed so as to overlap with the carriage 61 and the brace 63 (see FIG. 22).

The brace 63 is provided with a tire guard 64 for holding the front wheel FW (preceding carry-in wheel) when the bicycle BCL is mounted on the rack 62 in the horizontal state at the lower position. In the process in which the rack 62 and the brace 63 in the empty vehicle state rotate upward to reach the inverted state, the upper end portion of the tire guard 64 comes into contact with the support column 1 and resists the urging force of the standing urging spring (not shown). Gradually change the posture along the support column 1. When the rack 62 is stored upside down, the tire guard 64 is stored so as to overlap the rack 62 and the support column 1 (see FIG. 22).

As shown in FIGS. 22 to 25, the rack rotation mechanism 70 is mainly composed of an empty vehicle rocking drive gas spring 71 (hereinafter referred to as a rotating gas spring 71) forming an actuator for empty vehicle rocking drive, and is based on the rack rotation mechanism 70. The end is attached to the upper end of the carriage 61, while the tip of the piston rod 71R is attached to the front end of the rack 62. The push output of the piston rod 71R generates a moment whose arm length is the horizontal separation distance between the tip mounting position of the piston rod 71R and the rotation axis C62. The rack 62 is maintained in a horizontal state when the piston rod 71R is retracted (reduced) (see FIGS. 22 to 24). On the other hand, when the piston rod 71R protrudes (extends), the rack 62 and the brace 63 rotate upward with respect to the carriage 61 and are stored in an inverted state along the support column 1 (see FIG. 22). The rotating gas spring 71 of the rack rotation mechanism 70 acts to always store the front end portion of the rack 62 in an inverted state with a moment corresponding to the total load of the rack 62 (including rack accessories such as the brace 63). ..

By the way, the bicycle parking machine 100 of the third embodiment has a bogie lock mechanism 80, a slider lock mechanism 66, and a rack lock mechanism 90. Although these mechanisms will be described below, detailed description thereof will be omitted because similar mechanisms are described in Patent Document 3.

When the bogie 61 is in the predetermined lower stage position, the bogie lock mechanism 80 cannot raise or lower the bogie 61 based on the traction force of the gas spring 21GS and the constant load spring 29CS for raising and lowering the actual vehicle with respect to the support column 1 when the rack 13 is empty. The lock is activated so as to be (see FIG. 23), and the lock is released so as to be able to move up and down in the actual vehicle state (see FIG. 24).

As shown in FIG. 23, in the bogie lock mechanism 80 here, the wheel receiver 84 (first detecting means) that can swing back and forth on the rack 62 and is urged to lean backward is in a backward tilted state (actual vehicle). If the bogie 61 is in a predetermined lower stage position when it is in the non-detection state), it is maintained in the bogie lock operating state in which it cannot be raised or lowered. In this bogie lock operating state, as shown in FIG. 24, the bicycle BCL is carried into the rack 62, and the wheel receiver 84 (first detection means) receives the preceding carry-in wheel (for example, the front wheel FW of the bicycle BCL) and tilts forward. When the state (actual vehicle detection state) is reached, the bogie lock mechanism 80 switches the bogie 61 at a predetermined lower stage position to a bogie lock release state in which the bogie 61 can be raised and lowered in conjunction with the movement.

However, as shown in FIG. 22, when the rack 62 is stored in the inverted state, the bogie lock mechanism 80 switches to a non-interlocking state with the wheel receiver 84, and shifts to a state in which the bogie lock operating state is maintained. ..

As shown in FIG. 23, the slider lock mechanism 66 prohibits the slide pin 631 from sliding with respect to the elongated hole 621 when the carriage 61 is in a predetermined lower position and the rack 62 is in a horizontal state. The rack 62 and the brace 14 are locked by allowing the slide pin 631 to slide while locking the rack 62 and the brace 63 so as not to be able to rotate upward based on the moment by the rotating gas spring 71. Unlock so that it can rotate upward.

Switching between prohibition and permission of slide movement of the slide pin 631 is performed by an actuating member 94 (second detection means) arranged at the entrance / exit 65 of the rack 62, which is arranged at the entrance / exit 65 of the rack 62 and serves both as a means for detecting an empty state of the rack 62 and an artificial operation means. ) Is performed based on the operation. Similar to the operating member 54 of the first embodiment, the operating member 94 here is pushed down on the tip side by the wheel of the bicycle BCL being placed on the bicycle BCL or being artificially operated. As a result, it becomes an operating state (operation detection state).

However, as shown in FIG. 22, when the rack 62 is in the inverted storage state, the slider lock mechanism 66 moves the position of the slide pin 631 (slider center C61) to a position different from the position when the rack 62 is in the horizontal state. Since it is sliding, it cannot be locked, and the slide movement of the slide pin 631 is permitted.

The rack lock mechanism 90 operates while the rack lock mechanism 90 is in a rack lock operating state in which the rack 62 cannot move up and down with respect to the support column 1 when the rack 62 is in a predetermined lower position (see FIGS. 22 and 23) or an upper position (see FIG. 24). Based on the operation of the member 94 (second detection means), the rack lock operating state is released, and it is possible to move up and down with respect to the support column 1 at a predetermined lower position (see FIGS. 22 and 23) or an upper position (see FIG. 24). do.

Specifically, in the rack lock mechanism 90, the rack 62 is in a predetermined lower position (see FIGS. 22 and 23) or a predetermined upper position (see FIG. 24), and the operating member 94 is in an inactive state. Occasionally, the bogie 61 is engaged (locked here) with the support column 1 and locked so that the bogie 61 cannot be raised or lowered (see FIG. 2). When the operating state of the operating member 94 is detected in this rack lock operating state, the rack lock mechanism 90 disengages the trolley 61 from the support column 1 in conjunction with the detection operation, and the trolley 61 can be raised and lowered. Unlock so that (rack unlocked state).

When the rack 62 is stored in the inverted state, the rack lock mechanism 90 disengages the rack 62 from the support column 1 and maintains the unlocked state (rack unlocked state).

As described above, the bogie lock mechanism 80 is a mechanism that locks and holds the bogie 61 at a predetermined lower stage position to prohibit the rack 62 from ascending, and the lock can be released by receiving the wheels by the wheel receiver 84. Further, the slider lock mechanism 66 is a mechanism that locks and holds the rack 62 in the horizontal state to prohibit the transition to the inverted state, and the lock can be released by the operation of the operating member 94. On the other hand, the rack lock mechanism 90 is a mechanism that locks and holds the carriage 61 at predetermined lower and upper positions to prohibit the rack 62 from moving up and down, and the lock can be released by operating the operating member 94.

The operation of the bicycle parking machine 100 of the third embodiment described above will be described.

In the state of FIG. 24, when the operating member 94 is brought into the operating state by an artificial operation, the rack lock mechanism 90 switches the carriage 61 so as to be able to descend. Then, the bogie 61 and the rack 62 in the actual vehicle state are lowered to the position shown in FIG. 23 against the urging force of the actual vehicle elevating drive constant load spring 29CS and the gas spring 21GS. Since their urging force is almost balanced with the total weight of the bicycle BCL, trolley 61, and rack 62 (actually, it is set slightly larger than the total load), it is possible to push down the rack 62 with a slight force. can. At this time, the piston rod 21R of the gas spring 21GS is pulled back, and the moving pulleys 28A and 28C rise.

<Bicycle unloading + automatic inverted storage of rack = rack rotates with bicycle unloading: Fig. 23 → Fig. 22 → Fig. 21>
When the bicycle BCL moves backward on the rack 62 in the state of FIG. 23, the front wheel FW (preceding carry-in wheel) separates from the wheel receiver 84 and the actual vehicle is not detected. As a result, the bogie 61 is switched so as not to be able to rise by the bogie lock mechanism 80.
Further, when the bicycle BCL moves backward on the rack 62 and the front wheel FW (preceding carry-in wheel) is placed on the operating member 94, the operating member 94 is pushed down to be in the operating state. As a result, the rack 62 is switched to the inverted state by the slider lock mechanism 66. However, since the front wheel FW (preceding carry-in wheel) is mounted on the operating member 94, the rack 62 is maintained in a horizontal state due to its weight.
When the front wheel FW (preceding carry-in wheel) is separated from the operating member 94, the rack 62 automatically rotates by the urging force of the rotating gas spring 71, and shifts to the inverted storage state as shown in FIG. 21. Since the moment acting on the rack 62 by the rotating gas spring 71 is almost balanced with the total weight of the rack 62 (actually, it is set slightly larger than the total load), the rack 62 is shown with a slight force. It can be pushed up to the position of 21.

<Inverted storage of an empty rack = The empty rack rotates: Fig. 22 → Fig. 21>
In the state of FIG. 22, the actuating member 94 is brought into the actuated state by an artificial operation (for example, stepping on the actuating member 94), so that the slider lock mechanism 66 switches the rack 62 to the inverted state. Then, the rack 62 is pushed up to the position shown in FIG. 21 by using the urging force of the rotating gas spring 71. Since the urging force is almost balanced with the total weight of the rack 62 (actually, it is set slightly larger than the total load), the rack 62 can be pushed up with a small force.
