Description

The present invention relates to a rack storage structure for a bicycle parking machine.

In a bicycle parking machine having a vertical vertical lift type rack, a bicycle is carried into the rack at the lower position of the support column, and the rack in the actual vehicle state is stored and managed at the upper position. There are two types of storage methods for racks that have been emptied after the bicycle has been carried out: a type that slides in the upper position (that is, horizontal storage) in a horizontal state, and a flip-up storage (that is, inverted storage) that rotates around the base end. ) Is known. Patent Document 1 shows the latter flip-up storage type, and as compared with the former slide storage type, the amount of protrusion of the rack during storage can be reduced to save space.

However, in Patent Document 1, when an empty (that is, empty vehicle state) bicycle frame is flipped up and stored, the frame body (rack) and the link mechanism (side guard) are each in an L-shaped center-folded state (that is, a bent state). It becomes and is folded. Therefore, both of these members are apt to fall into insufficient strength and lack of durability, and there is a concern that not only their own damage but also the risk of the mounted bicycle falling.

Japanese Patent No. 5303535

An object of the present invention is to provide a rack storage structure having excellent strength and durability by storing an empty rack and a side guard in an inverted state while maintaining a rigid structure without bending in a vertically elevating bicycle parking machine. There is.

Means for Solving Problems and Effects of Invention

In order to solve the above problems, the rack storage structure of the bicycle parking machine of the present invention is
It has a predetermined height along a column erected in a tubular shape in the vertical direction, and is arranged so as to be able to move up and down between the lower position and the upper position of the column by applying a traction force, and the lower position. A base body (for example, a trolley) that is locked to the support column and functions as a fixed link.
The base end portion of the base body is rotatably supported around the rotation axis in the width direction and extends in a cantilever shape in the longitudinal direction (for example, in the shape of a gutter) with respect to the lower portion of the base body, and the bicycle is carried in and out of the tip. When the doorway is formed and the bicycle is not mounted, the moment around the rotation axis applied to the base end rotates from the horizontal state to the inverted state along the support column with respect to the base body at the lower stage position. With a rack that acts as a possible rotary drive link,
In order to prevent or suppress rolling motion, which is rolling vibration (that is, left-right tilt) of a bicycle carried in and out of the rack in the horizontal state at the lower position, the rack is arranged on both sides in the width direction and one end of itself. The portion is swingably supported around the swing axis in the width direction with respect to the upper portion of the base body, while the other end portion is integrally formed along the longitudinal direction with the middle portion (closer to the tip portion) of the rack. By forming a slider (specifically, a slide pin or a slide block) that is slidably engaged and supported with respect to the guide portion (specifically, a long hole or a rail), the base body and the rack are separated from each other. It is equipped with a side guard (for example, a brace) that is hung on the bicycle and functions as a rotation-driven link in the empty vehicle state.
At the lower position, the base body, the rack, and the side guard form a triangular shape having a rigid body structure when viewed from the width direction, and the rack and the side guard crank movement via the slider in the empty state. The crank mechanism is configured,
By applying the moment to the base end portion of the rack in the empty state and the horizontal state, the rack and the side guard move along the longitudinal direction at the guide portion, while the rack and the side guard form the base body. It is characterized in that it rotates upward and is stored in an inverted state along the support column.

In this way, the rack and side guards that have been emptied after the bicycle has been carried out do not bend or sag until they are stored in the inverted state, and the rotary drive link and rotary driven link that constitute the rotary slider crank mechanism. The rigid structure can be maintained. Therefore, it can be a bicycle parking machine that is excellent in strength and durability and has a robust rack storage structure, and can safely and reliably store and manage various bicycles from lightweight to heavyweight.

The above-mentioned "triangular shape of rigid body structure" means "a rigid triangular shape having rigidity on each side is formed by a base body, a rack and a side guard which are components of a rotating slider crank mechanism, and the rack and the side guard are inverted. It means that there are no bent or slack parts when stored in the state. " In the rotary slider crank mechanism, the "guide portion" can be composed of a long hole, the "slider" can be composed of a slide pin, the "guide portion" can be composed of a rail, and the "slider" can be composed of a slide block. Further, in the above-mentioned "rotation slider crank mechanism", since the rack as a rotation drive link operates only within a rotation angle (1/4 rotation) of about 90 ° from the horizontal state to the inverted state along the support column, "1 /". It can also be referred to as a "four-turn slider crank mechanism".

By the way, the application (mechanism) of the traction force to the base body functions (acts) so that the base body is always pulled upward by the traction force corresponding to the total load of the base body, the rack, the side guard, and the rack-mounted bicycle. Further, the application (mechanism) of the moment to the base end portion of the rack functions (acts) so that the rack is always stored in the inverted state with the moment corresponding to the total load of the rack and the side guard.

The "side guard" is a so-called brace that is hung diagonally on both sides of the rack in the width direction to prevent the mounted bicycle from falling, and is also commonly called a brace.

Bicycles are carried in from the entrance and exit of the rack in the horizontal state at the above-mentioned lower position, and the rack in the actual vehicle state on which the bicycle is mounted is moved up and down together with the base body between the lower position and the upper position.
When the base body is in the lower position, the lower stop mechanism locks the support column so that the base body cannot be raised or lowered based on the traction force when the vehicle is empty, and unlocks the base body so that it can be raised or lowered in the actual vehicle state. When,
When the base body is in the lower position and the rack is in the horizontal state, by prohibiting the sliding movement of the slider with respect to the guide part, the rack and side guards are locked so that they cannot rotate upward based on the moment with respect to the base body. It is equipped with a rotation stop mechanism that operates and unlocks so that it can rotate upward by allowing slide movement.
The rotation stop mechanism is unlocked only when the base body is in the lower position, the rack is in the horizontal state, and the lower stop mechanism is locked.

In this way, in order to store the rack and side guard in the inverted state, it is essential that the lower stop mechanism is locked, that is, the base body is fixed to the support column, so that safety is ensured and erroneous operation is unlikely to occur. ..

Based on detecting the empty state of the rack, the lower stop mechanism locks the base body to the lower position of the support column, and the rotation stop mechanism allows the slider to slide with respect to the guide portion to allow the rack and the base body to move. Unlock the side guard so that it can rotate upward.

In this way, the lower stop mechanism is locked and the rotation stop mechanism is unlocked when the rack is detected as empty, so that the rack and the side guard can be safely stored in the inverted state.

Specifically, when the bicycle is carried out from the rack in the actual vehicle state to be in the empty state, the lower stop mechanism is locked and then the rotation stop mechanism is unlocked.

In this way, by giving priority to the locking operation of the lower stop mechanism, the lifting and lowering locking operation of the base body with respect to the support is performed prior to the unlocking of the slider with respect to the guide portion (rotation stop mechanism). As a result, the rack and side guards rotate upward with reference to the base body fixed to the support column, and are stored in an inverted state on a stable track.

As an example, when the following unloading wheel (for example, the front wheel) retracts from the wheel receiver (first detecting means), the lower unloading wheel (that is, the empty vehicle transition state) is detected and the lower stop mechanism is locked, and then the following unloading wheel (first detection means) is activated. For example, when the front wheel) is carried out (passed) from the actuating member (second detection means) at the entrance / exit, the rotation stop mechanism may be unlocked by detecting the carry-out end state (that is, the completely empty state).

When the rack and side guard described above are stored in an inverted state, the lower stop mechanism maintains the lock operation, and the rotation stop mechanism maintains the unlock.

The lower stop mechanism and rotation stop mechanism maintain the state at the start of storage until the rack and side guards are stored in the inverted state, so malfunctions are prevented until the storage is completed in the inverted state, and the rack is in a horizontal state. It is possible to prevent malfunction even when returning to the (carry-in standby state).

When the rack stored in the above-mentioned inverted state is artificially rotated in the reverse direction around the rotation axis against the moment, the rack functions as a reverse rotation drive link and the side guard functions as a reverse rotation driven link.
When the rack returns to the horizontal state with respect to the base body in the lower position, the rotation stop mechanism prohibits the sliding movement of the slider with respect to the guide portion, so that the rack and the side guard cannot rotate upward with respect to the base body. It locks so that it becomes.

In this way, when the rack is rotated in the reverse direction from the inverted state to return to the horizontal state (carry-in standby state), the rotation stop mechanism is locked, so that the rack returns to the inverted state without returning to the horizontal state. It is possible to prevent malfunctions such as (turning back), and the bicycle can be carried into the rack at the lower position without any trouble.

At the lower position described above, the base body, rack, and side guards constituting the rotary slider crank mechanism have a pseudo-right-angled triangular shape in which the base body and the rack intersect at substantially right angles and the side guards form hypotenuses.
In the inverted state, the rack is stored so as to overlap the base body and the side guard when viewed from the width direction.

In this way, by making the shapes formed by the base body, the rack, and the side guards closer to a right triangle at the lower position, it is possible to reduce the size and compactness of the rotary slider crank mechanism and the entire bicycle parking machine.

When the bicycle is carried into the rack in the horizontal state at the lower position described above, the tire guard for supporting both sides of the preceding wheel (for example, the front wheel) from above is provided near the high position side end of the side guard forming the hypotenuse. It is provided in a shape that protrudes upward from one side in the width direction, bypasses the tire, and reaches the other side (for example, an inverted U shape).
The tire guard in the empty state changes its posture along the support column (while its upper end is in contact with the support column) in the process of the rack and side guard rotating upward to reach the inverted state, and is viewed from the width direction. It overlaps with the rack and is stored.

In this way, the tire guard attached to the side guard functions as a tire holder that stands up from the side guard and holds the tire inside when the bicycle is carried into the rack. On the other hand, when the empty rack is stored in an inverted state, the tire guard can function as a storage guide that is gradually folded and stored in contact with the support column.

Hereinafter, embodiments of the present invention will be described with reference to the examples shown in the drawings.

The inverted storage type bicycle parking machine 100 shown in FIG. 1 is a rotary slider which is a basic configuration for realizing an inverted storage function, that is, a function of storing an empty rack 12 on which a bicycle BCL is not mounted in an inverted state (see FIG. 7). The crank mechanism 10, the bogie lifting mechanism 20 (traction force applying mechanism) and the rack rotation mechanism 30 (moment applying mechanism) which are means for driving each part thereof, and the bogie which is a means for regulating the operation of each part. It includes a lock mechanism 40 (lower stop mechanism), a slider lock mechanism 50 (rotation stop mechanism), and a rack lock mechanism 60 (movement stop mechanism).

As shown in FIGS. 1 and 2, the rotary slider crank mechanism 10 includes a carriage 11 (base body) that functions as a fixed link, a rack 12 that functions as a rotary drive link, and a brace 13 (side) that functions as a rotary driven link. It has a guard) and is formed in a rigid triangular shape when viewed from the front (that is, when viewed from the width direction of the rack 12).

The trolley 11 has a constant height along the stanchion 1 erected in a tubular shape in the vertical direction, and a traction force is applied by the trolley elevating mechanism 20 to provide a traction force between the lower and upper positions of the stanchion 1. It is arranged so as to be able to move up and down by a roller 111 (see FIG. 3) (details will be described later). Further, the bogie 11 is locked to the support column 1 at the lower position by the bogie lock mechanism 40 (details will be described later), and functions as a fixed link in the rotary slider crank mechanism 10.

The rack 12 has a front end portion (base end portion) rotatably supported about the rotation axis 120 (rotation axis) in the width direction with respect to the lower portion of the carriage 11, and extends in a gutter shape in the longitudinal direction in a cantilever shape. An entrance / exit 123 for loading / unloading the bicycle BCL is formed at (rear end). A moment centered on the rotation shaft 120 is applied to the front end portion by the rack rotation mechanism 30 in the empty state, and the rack rotation mechanism 30 is rotatably arranged from the horizontal state to the inverted state along the support column 1 with respect to the trolley 11 at the lower stage position. (Details will be described later), the rotary slider crank mechanism 10 functions as a rotary drive link. Further, the rack 12 can be locked to the support column 1 by the rack lock mechanism 60 (details will be described later).

A pair of braces 13 are arranged on both sides of the rack 12 in the width direction, and one end portion (upper end portion in FIGS. 1 to 4) of each of the left brace 13L and the right brace 13R (see FIGS. 3 and 4) is relative to the upper portion of the carriage 11. , It is supported so as to be swingable around the swing shaft 130 (swing axis) in the width direction. On the other hand, the other ends of the left and right braces 13L and 13R (lower ends in FIGS. 1 to 4) are in the middle of the rack 12 and are fixed toward the rear end (tip) in the longitudinal direction of the plate-shaped member 122. A slide pin 131 (slider) that is engaged and supported so as to be slidably movable in the empty vehicle state at the lower stage is formed with respect to the elongated hole 121 (guide portion) integrally formed along the above, and the rotary slider crank mechanism 10 rotates. Acts as a driven link. Further, the brace 13 is a pair of left and right braces hung diagonally between the bogie 11 and the rack 12, and the rolling vibration of the bicycle BCL carried in and out of the rack 12 in the horizontal state at the lower position (that is,). It prevents or suppresses the rolling motion (tilt left and right), or prevents the on-board bicycle BCL from falling. Further, the slide movement of the slide pin 131 with respect to the elongated hole 121 can be locked by the slider lock mechanism 50 (details will be described later).

That is, at the lower position of the support column 1, the carriage 11, the rack 12, and the brace 13 have a pseudo-right-angled triangular rigid body structure in which the carriage 11 and the rack 12 intersect at a substantially right angle and the brace 13 forms a hypotenuse when viewed from the front. Have. Strictly speaking, a pseudo-right triangle is formed in which a straight line connecting the rotation axis C120 and the swing axis C130 and a straight line connecting the rotation axis C120 and the slider center C131 intersect at a substantially right angle. As described above, the rotary slider crank mechanism 10 in which the rack 12 and the brace 13 are cranked via the slide pin 131 is configured. Therefore, in the empty vehicle state, the slide pin 131 slides in the elongated hole 121 along the longitudinal direction, and the rack 12 and the brace 13 rotate upward with respect to the carriage 11 and are stored in an inverted state along the support column 1. Then, in this inverted state, the rack 12 is housed so as to overlap the trolley 11 and the brace 13 in a front view (see FIG. 7).

By using such a rotary slider crank mechanism 10, it is possible to realize compactness in the inverted storage structure of the bicycle parking machine 100. Further, the trolley 11, the rack 12, and the brace 13 form a rigid triangular shape on each side, and when the rack 12 and the brace 13 are stored in an inverted state, no bent portion or slack portion is generated.

In the rotary slider crank mechanism 10 of this embodiment, the rack 12 as a rotary drive link operates only within a rotation angle (1/4 rotation) of about 90 ° from the horizontal state to the inverted state along the support column 1 (FIG. 7). (See), it can also be referred to as a "1/4 rotation slider crank mechanism".

In general, following the example of a structure composed of a "rotary slider crank mechanism" (for example, a radial engine), and in light of the name of the mechanism, the slide pin 131 of the brace 13 is a rotary drive link. It is usually a (driving node), but in this embodiment, the rack 12 (long hole 121) is used as a rotation drive link in consideration of the strength of the constituent members.

The front wheel FW of the rack-mounted bicycle BCL (that is, near the high position side end of the brace 13 forming the hypotenuse) and between the wheel receiver 44 (described later) and the swing shaft 130 in front view. The tire guard 132 that holds the preceding carry-in wheel) stands upright from the brace 13 and is provided so as to be undulating. The tire guard 132 is formed in an inverted U shape that protrudes upward from one brace (for example, left brace 13L), bypasses the tire of the front wheel FW, and reaches the other brace (for example, right brace 13R), and is in a horizontal state at the lower position. When the bicycle BCL is carried into the rack 12, both sides of the front wheel FW are straddled from above and held inward (see FIG. 11). In this way, when the bicycle BCL is carried into the rack 12, the tire guard 132 functions as a tire holder for holding the tires of the front wheel FW inside.

An upright urging spring 133 is erected between the brace 13 and the tire guard 132, and keeps the tire guard 132 in an upright posture with respect to the brace 13. In the process in which the empty rack 12 and the brace 13 rotate upward to reach the inverted state, the upper end portion of the tire guard 132 comes into contact with the support column 1 and becomes the support column 1 against the urging force of the standing urging spring 133. The posture is gradually changed along the line, and the rack 12 and the support column 1 are overlapped and stored in front view (see FIG. 7). As described above, when the empty rack 12 is stored in the inverted state, the tire guard 132 functions as a storage guide that comes into contact with the support column 1 and is gradually folded and stored.

Returning to FIG. 1, the elevating gas spring 21, which forms the main part of the bogie elevating mechanism 20, has a base end portion attached to the upper end portion in the column 1, and the tip end portion (lower end portion) of the piston rod 21R protruding downward. A moving pulley 22 is attached to the. Further, a fixed pulley 23 is also attached to the upper end portion in the support column 1. One end of the connecting wire 24 is fixed at a predetermined position in the support column 1, the moving pulley 22 and the fixed pulley 23 are wound in this order, and then the other end is fixed to the upper end surface of the carriage 11. When the piston rod 21R moves in and out (contracts), the rack 12 is in the lower position together with the bogie 11, and when the bicycle BCL is carried in, the rack 12 is in the actual vehicle state (see FIG. 11). Due to the protrusion (extension) of the piston rod 21R, the rack 12 rises to the upper position together with the carriage 11 to store the bicycle BCL (see FIG. 13).

As shown in FIGS. 1 and 2, the rack rotation mechanism 30 is mainly composed of a rotating gas spring 31, and its base end is attached to the upper end of the carriage 11, while the tip of the piston rod 31R is the rack 12. It is attached to the front end of the. The push output of the piston rod 31R generates a moment whose arm length is the horizontal separation distance between the tip mounting position of the piston rod 31R and the rotation axis C120. The rack 12 is maintained in a horizontal state when the piston rod 31R is retracted (retracted) (see FIG. 5). On the other hand, when the piston rod 31R protrudes (extends), the rack 12 and the brace 13 rotate upward with respect to the carriage 11 and are stored in an inverted state along the support column 1 (see FIG. 7).

By the way, the elevating gas spring 21 of the trolley elevating mechanism 20 acts to constantly pull up the trolley 11 upward with a traction force corresponding to the total load of the trolley 11, the rack 12, the brace 13, and the rack-mounted bicycle BCL. Further, the rotating gas spring 31 of the rack rotating mechanism 30 acts so as to always store the front end portion of the rack 12 in an inverted state with a moment corresponding to the total load of the rack 12 and the brace 13.

The bogie lock mechanism 40 shown in FIGS. 1 and 2 locks the bogie 11 so that when the bogie 11 is in the lower position, the bogie 11 cannot be raised or lowered based on the traction force of the elevating gas spring 21 with respect to the support column 1 in the empty state. It operates (see FIG. 3) and acts to unlock (see FIG. 12) so that it can be raised and lowered in the actual vehicle state.

Specifically, as shown in FIG. 3, the lock arm 41 is swingably attached to the support shaft 42 in the width direction arranged on the carriage 11, and the lower end portion of the lock arm 41 is bent forward in an L shape. The locking claw 412 is formed. The locking claw 412 can be engaged with the arm engaging portion 2 formed at the lower position of the support column 1, and the arm urging spring 43 is arranged between the carriage 11 and the upper end portion of the lock arm 41 to engage. The stop claw 412 is always urged in the direction (front side) in which it engages with the arm engaging portion 2. A protrusion 411 is formed so as to protrude downward from the rear portion of the locking claw 412.

Further, near the front end of the rack 12, a wheel receiver 44 for receiving the front wheel FW (preceding carry-in wheel) of the carry-in bicycle BCL is arranged so as to swing back and forth. The wheel receiver 44 is connected to an extension rod 45 extending in the front-rear direction, and the extension rod 45 is always urged forward by a rod urging spring 46 arranged between the wheel receiver 44 and the rack 12. The front end portion of the extension rod 45 is bent in an L shape in the width direction to form a hook portion 451, and the hook portion 451 surrounds the periphery of the protrusion 411 formed at the lower end portion of the lock arm 41 and is located in front of the extension rod 45. ..

As shown in FIG. 3, when the rack 12 is empty, that is, when the front wheel FW is not mounted on the wheel receiver 44, the wheel receiver 44 tilts backward and the extension rod 45 advances due to the urging force of the rod urging spring 46. The portion 451 is located in front of the protrusion 411. The lower end of the lock arm 41 is urged forward by the arm urging spring 43, and the locking claw 412 engages with the arm engaging portion 2 and is locked. That is, the carriage lock mechanism 40 locks the carriage 11 so that it cannot move up and down with respect to the support column 1.

On the other hand, as shown in FIG. 12, when the rack 12 is in the actual vehicle state, that is, when the front wheel FW is placed on the wheel receiver 44, the wheel receiver 44 tilts forward against the urging force of the rod urging spring 46 and retracts the extension rod 45. The hooking portion 451 engages with the protrusion 411 and is pulled backward. The locking claw 412 of the lock arm 41 rotates rearward against the total urging force of the arm urging spring 43 and the rod urging spring 46, and the engagement with the arm engaging portion 2 is released. That is, the carriage lock mechanism 40 unlocks the carriage 11 so that the carriage 11 can move up and down with respect to the support column 1.

As shown in FIG. 9, when the rack 12 is stored in the inverted state, that is, when the rack 12 rotates about the rotation shaft 120, the hook portion 451 goes around the outside of the protrusion 411 and gradually moves away. .. The lower end of the lock arm 41 is urged forward by the arm urging spring 43, and the locking claw 412 engages with the arm engaging portion 2 and is locked. That is, the carriage lock mechanism 40 locks the carriage 11 so that it cannot move up and down with respect to the support column 1.

Returning to FIGS. 1 and 2, the slider lock mechanism 50 prohibits the sliding movement of the slide pin 131 with respect to the elongated hole 121 when the carriage 11 is in the lower position and the rack 12 is in the horizontal state. The lock is operated so that the rack 12 and the brace 13 cannot rotate upward based on the moment by the rotating gas spring 31 (see FIG. 4). On the other hand, the slider lock mechanism 50 unlocks the rack 12 and the brace 13 so that they can rotate upward by allowing the slide pin 131 to slide (see FIG. 6).

Further, the rack lock mechanism 60 locks the rack 12 to the support column 1 to make it impossible to move at the lower position or the upper position (see FIG. 4 or 15), and releases the lock to move the rack lock mechanism 60. It is switched to the unlocking mode (see FIG. 6) that enables it. The switching between the lock operation mode and the lock release mode in the rack lock mechanism 60 is based on the operation of the operating member 64 which is arranged at the entrance / exit 123 of the rack 12 and also serves as an empty vehicle state detecting means and an artificial operating means. This is performed at the same time as the locking operation and unlocking of the slider lock mechanism 50 are interlocked with each other (see FIGS. 4 and 6).

Specifically, as shown in FIG. 4, a lower engaging portion 4 is formed at the lower position of the support column 1 so that the amount of protrusion to the rear side increases as it goes downward, and a stopper urging spring is formed below the rack 12. A rack stopper 61 that is always urged to the support column side (front side) by 62 is provided. The rack stopper 61 is connected to an operating member 64 provided at the entrance / exit 123 in a form that serves as both an empty vehicle state detecting means and an artificial operating means via a connecting rod 63 extending in the longitudinal direction along the rack 12. ..

The support plate 124 is fixed to the rack 12, and one end of the rotation lock plate 51 is rotatably provided around the rotation shaft 52 in the width direction arranged on the support plate 124. A lock claw 511 including a notch that opens downward is formed at the other end of the rotary lock plate 51, and the notch of the lock claw 511 can be fitted to the slide pin 131 from above. An inclined elongated hole 513 is formed between the rotating shaft 52 and the lock claw 511 in a direction intersecting the major axis arrangement direction (that is, the horizontal direction) of the elongated hole 121, and protrudes from the connecting rod 63 in the width direction. The formed operation pin 53 is inserted into the inclined elongated hole 513. A slope portion 512 that is inclined in a direction different from that of the inclined elongated hole 513 is formed at the tip portion of the rotary lock plate 51 further from the lock claw 511.

As shown in FIG. 4, when the carriage 11 is in the lower position and the rack 12 is in the horizontal state, if the operating member 64 does not operate and the connecting rod 63 is not pulled, the rack stopper 61 is a stopper urging spring. It is urged to the front side by 62, and is locked to the lower side after riding on the lower engaging portion 4. That is, the rack lock mechanism 60 locks the rack 12 to the support column 1 so as to be immovable. Further, since the operation pin 53 is located on the front end side of the inclined elongated hole 513 and does not rotate the rotation lock plate 51, the notch of the lock claw 511 is fitted to the slide pin 131 to lock the slide movement, and the rack 12 and The lock is operated so that the brace 13 cannot rotate upward. That is, the slider lock mechanism 50 prohibits the slide movement of the slide pin 131 and locks the slide pin 131 so that it cannot be stored upside down.

On the other hand, as shown in FIG. 6, when the carriage 11 is in the lower position and the rack 12 is in the horizontal state, when the operating member 64 operates and the connecting rod 63 is pulled, the rack stopper 61 is a stopper urging spring. It moves to the rear side against 62, and the lock with the lower engaging portion 4 is released. That is, the rack lock mechanism 60 is unlocked so that the rack 12 can be moved by unlocking the support column 1. Further, the operation pin 53 moves to the rear side of the inclined elongated hole 513 to rotate the rotation lock plate 51 upward, and the notch of the lock claw 511 and the slide pin 131 are released from each other to allow the slide movement. Unlock so that the rack 12 and brace 13 can rotate upward. That is, the slider lock mechanism 50 allows the slide pin 131 to slide and unlocks it so that it can be stored upside down.

When the rack 12 is stored in the inverted state, that is, when the rack 12 rotates about the rotation shaft 120, the rack stopper 61 gradually moves away from the lower engaging portion 4. That is, the rack lock mechanism 60 maintains the unlocking so that the rack 12 can be moved by releasing the lock on the support column 1. Further, as shown in FIG. 8, the slide pin 131 can slide and move in the elongated hole 121 regardless of the rotation lock plate 51. That is, the slider lock mechanism 50 allows the slide pin 131 to slide and keeps the lock released so that it can be stored upside down.

Further, when the rack 12 returns from the inverted state to the horizontal state, the rack stopper 61 is locked to the lower engaging portion 4 by shifting in the direction opposite to the storage in the inverted state, and the notch of the lock claw 511 slides. It fits into the pin 131 and locks the slide movement. At that time, when the slide pin 131 slides in the elongated hole 121 in the direction opposite to the arrow in FIG. 8, the slide pin 131 slips into the slope portion 512 of the lock claw 511 and rotates around the rotation shaft 52. The 51 is rotated upward, and the notch of the lock claw 511 fits into the slide pin 131 to lock the slide movement.

In this way, when the bogie 11 is in the lower position and the rack 12 in the horizontal state becomes empty due to the carrying out of the bicycle BCL (see FIG. 5), the bogie lock mechanism 40 raises and lowers the bogie 11 with respect to the support column 1. The lock is activated so as to be impossible (see FIG. 3), the slider lock mechanism 50 allows the slide pin 131 to slide with respect to the elongated hole 121, and the rack lock mechanism 60 releases the lock of the rack 12 with respect to the support column 1. By interlocking with each other and unlocking at the same time so as to enable movement (see FIG. 6), the rack 12 and the brace 13 rotate upward with respect to the carriage 11 based on the moment by the rotating gas spring 31. It is stored in an inverted state along the support column 1 (see FIG. 7).

Further, when the rack 12 is returned from the inverted state to the horizontal state by an artificial operation of the operating member 64, the slider lock mechanism 50 locks the slide pin 131 with respect to the elongated hole 121, and the rack lock mechanism 60 determines the lock operation. The locking and locking operation of the rack 12 with respect to the support column 1 is executed in conjunction with each other (see FIG. 10).

In this way, the rack 12 and the brace 13 in which the bicycle BCL is carried out and become empty do not bend or sag until they are stored in the inverted state, and the rotary drive link and the rotary drive link constituting the rotary slider crank mechanism 10 and the brace 13 are formed. A rigid structure can be maintained as a rotation-driven link. Therefore, the bicycle parking machine 100 can be provided with a rack storage structure that is excellent in strength and durability and has a robust rack storage structure, and can safely and reliably store and manage various bicycles from light weight to heavy weight.

Further, the rack 12 which has been emptied by carrying out the bicycle BCL from the rack 12 at the lower position is automatically stored in the inverted state, and the rack 12 which has been brought into the rack 12 at the lower position and is in the actual vehicle state is the upper stage. Stored and managed at the location. Therefore, in the inverted storage type bicycle parking machine 100, both the carrying-out work and the carrying-in work of the bicycle BCL are performed at the lower position, so that the work load is reduced and erroneous operation is less likely to occur.
