Description

  The present invention relates to a bicycle parking machine.

  In a bicycle parking machine having a vertical up-and-down lift rack, a bicycle is carried into the rack at a lower position of the column, and a rack in an actual vehicle state is stored and managed at the upper position. As a storage method for the rack when the bicycle is unloaded, the rack is stored in the horizontal position in the upper position (that is, horizontally stored), and the rack is swung up around the base end (that is, stored upside down). ) Type is known. Patent document 1 shows the latter flip-up storage type, and 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, the height position of the gantry (rack) differs between when the bicycle is unloaded and when it is loaded. In other words, by pushing down the gantry to a lower parking posture position than the parking standby posture position and releasing the rotation of the gantry (that is, by moving from the upper parking standby posture position to the lower parking posture position) Only when the bicycle is carried out after the switching means is switched to the non-engagement position and the rotation lock of the gantry is released), the empty (that is, empty) gantry is automatically flipped up. Can be stored. On the other hand, after passing through the parking posture position from the flip-up posture position, the rotation lock operation operation of the empty platform at the parking standby posture position (that is, the operation of returning from the lower parking posture position to the upper parking standby position) Thus, the bicycle can be carried in only when the switching means is switched to the engaged position and the rotation lock of the gantry is operated. In this way, carrying out the bicycle at the lower parking position and performing the bicycle at the upper parking standby position is compared to carrying the bicycle at a fixed height position. Therefore, the operation is complicated and the work load becomes large, and an erroneous operation is likely to occur. In particular, there is a problem in work safety when the bicycle is automatically stowed to the position where the stand is lifted up when the bicycle is taken out, and when the stand is allowed to move up when the bicycle is taken in. It can happen.

Japanese Patent No. 5303535

  The problem of the present invention is that the work of carrying out the bicycle for automatically storing the rack in the inverted state and the work of carrying in the bicycle for storage and management in the rack are performed at the same height position. The object is to provide a bicycle parking machine that is simple, safe and less susceptible to erroneous operation.

Means for Solving the Problems and Effects of the Invention

In order to solve the above problems, the bicycle parking apparatus of the present invention
A base body (e.g., a carriage) that can be moved up and down between a lower position and an upper position of the support by applying a traction force along a support that is erected in a cylindrical shape in the vertical direction;
The base end of the base body is supported so as to be rotatable around a rotation axis in the width direction and extends in a cantilever shape in the longitudinal direction (for example, in the shape of a bowl), and is used for carrying a bicycle in and out of the tip. Rotating from a horizontal state to an inverted state along the support column with respect to the base body at the lower position by a moment around the rotation axis applied to the base end portion in an empty state where a bicycle is not mounted while an entrance / exit is formed A rack that is capable of being lifted and lowered together with the base body between the lower position and the upper position in a real vehicle state in which a bicycle is mounted;
In order to prevent or suppress a rolling motion that is a rolling vibration (that is, a left-right tilt) of a bicycle carried in and out of the horizontal rack at the lower position, it is disposed on both sides in the width direction of the rack and one end of itself. The portion is supported so as to be swingable about the swing axis in the width direction with respect to the upper portion of the base body, and the other end portion is integrally formed along the longitudinal direction in the middle portion of the rack (near the tip portion). By forming a slider (specifically a slide pin or slide block) that is slidably engaged with and supported by a guide portion (specifically, a long hole or rail), the base body and the rack are formed. Side guards (e.g. braces),
When the base body is at the lower position, the base body is locked so that the base body cannot be lifted or lowered based on the traction force in the empty state, and can be lifted and lowered in the actual vehicle state. A lower stop mechanism for unlocking,
When the base body is in the lower position and the rack is in the horizontal state, the sliding movement of the slider with respect to the guide portion is prohibited, whereby the rack and the side guards based on the moment with respect to the base body are prevented. A rotation stop mechanism that locks so that upward rotation is impossible, and allows the slide movement to unlock so that upward rotation is possible;
A movement stop mechanism that is switched between a lock operation mode in which the rack is locked to the support column and cannot be moved at the lower position or the upper position, and a lock release mode in which the movement is released by releasing the lock. With
When the base body is in the lower position and the horizontal rack is in the empty state as the bicycle is taken out, the lower stop mechanism is locked so that the base body cannot be raised or lowered with respect to the column. The rotation stop mechanism permits the slider to move relative to the guide portion, and the movement stop mechanism unlocks the rack from the support so that the rack can move. The rack and the side guard are rotated upward relative to the base body based on the moment by being unlocked in conjunction (for example, simultaneously), and are stored in an inverted state along the support column. .

  In this way, the rack that has been unloaded from the rack at the lower position is automatically stored in an inverted state, and the rack that has been loaded into the rack at the lower position and is in the actual state is stored at the upper position. Managed. Therefore, in the inverted storage type bicycle parking machine, the bicycle carrying-out work and the carrying-in work are both performed at the lower position, so that the work load is reduced and erroneous operations are less likely to occur.

  Moreover, as the bicycle is carried out at the lower position, the lower stop mechanism is used to lock the base body up and down with respect to the support, and the rotation stop mechanism is used to unlock the slider with respect to the guide portion and the movement stop mechanism. The rack unlocking operation with respect to the column is performed in conjunction with each other. In other words, triggered by the work of carrying out the bicycle from the lower rack, the base body is fixed to the column, the relative movement between the rack (the guide portion) and the side guard (the slider), and the unlocking of the rack with respect to the column is released. Therefore, the automatic storing operation to the inverted state of the rack is easily and safely performed, and it is difficult to cause an erroneous operation.

  Furthermore, when the rack is returned to the horizontal state from the inverted state, the slider locking operation with respect to the guide portion by the rotation stop mechanism and the rack locking operation with respect to the column by the movement stop mechanism are interlocked with each other. Can be executed. Therefore, even if the lifting of the base body with respect to the column is released by the lower stop mechanism triggered by the work of loading the bicycle into the rack at the lower position, the rack is locked to the column by the lock operation by the movement stop mechanism. The danger that the rack in the actual vehicle will rise unexpectedly is avoided. Thus, by providing the rotation stop mechanism and the movement stop mechanism so as to be unlocked or locked in conjunction with each other, the safety in carrying out and carrying in the bicycle in the lower rack is improved. Can do.

  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-equipped bicycle. Further, the application of a moment (mechanism) to the base end portion of the rack functions (acts) so that the rack is always rotated and stored in an inverted state at a moment corresponding to the total load of the rack and the side guard.

  The “side guard” is a so-called brace that is slantedly crossed on both sides in the width direction of the rack to prevent the mounted bicycle from falling, and is also commonly referred to as a brace.

  A rotating slider crank mechanism is configured in which the base body, the rack, and the side guard have a rigid triangular shape when viewed in the width direction at the lower position, and the rack and the side guard perform a crank motion via the slider in an empty state. When the bicycle is unloaded, the rack and the side guard, which are in an empty state, are not bent or slacked until they are stored in an inverted state. A rigid body structure can be maintained as a link. Therefore, it is possible to provide a bicycle parking apparatus that is excellent in strength and durability, has a robust rack storage structure, and can store and manage various bicycles from light weight to heavy weight safely and reliably.

  The above-mentioned “triangular shape of rigid body structure” means “a solid triangular shape having rigidity on each side by a base body, a rack and a side guard, which are components of a rotating slider crank mechanism, and the rack and side guard are inverted. This means that a bent part or a slack part does not occur when stored in a state. In the rotary slider crank mechanism, the “guide portion” can be constituted by a long hole, the “slider” can be constituted by a slide pin, the “guide portion” can be constituted by a rail, and the “slider” can be constituted by a slide block. Further, in the above “rotating slider crank mechanism”, the rack as the rotational drive link operates only in the range of about 90 ° rotation angle (1/4 rotation) from the horizontal state to the inverted state along the support column. It can also be referred to as a “four-turn slider crank mechanism”.

  The rotation stop mechanism and the movement stop mechanism are unlocked only when the above-described base body is in the lower stage position, the rack is in a horizontal state, and the lower stage stop mechanism is locked.

  As described above, in order to store the rack and the side guard in an inverted state, it is essential that the lower stop mechanism is locked, that is, the base body is fixed to the support column. Therefore, safety is ensured and erroneous operation is unlikely to occur. .

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

  In this way, the locking action of the lower stop mechanism has priority, so that the lifting / lowering lock operation of the base body with respect to the support can be performed by unlocking the slider with respect to the guide (rotation stop mechanism) or unlocking the rack with respect to the support (moving stop). Performed prior to the mechanism). As a result, the rack and the side guard rotate upward with the base body fixed to the support as a reference, and are stored in an inverted state on a stable track.

  More specifically, the rack includes a first detection means for detecting a bicycle in an intermediate state for locking the lower stop mechanism, and an unloading mechanism for simultaneously unlocking the rotation stop mechanism and the movement stop mechanism. Second detection means for detecting the bicycle in the finished state is provided.

  By providing such first and second detection means, it becomes easy to prioritize the operation timing of the lower stage stop mechanism and synchronize the operation timings of the rotation stop mechanism and the movement stop mechanism.

  As an example, when the subsequent carry-out wheel (for example, the front wheel) moves backward from the wheel receiver (first detection means), the carry-out intermediate state (that is, the empty vehicle transition state) is detected, and the lower stop mechanism is locked, and then the subsequent carry-out wheel ( For example, when the front wheel is unloaded (passed) from the door operating member (second detecting means), the unloading end state (that is, the complete empty state) is detected and the rotation stop mechanism and the movement stop mechanism are unlocked. There is.

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

  Since the lower stage stop mechanism, the rotation stop mechanism, and the movement stop mechanism maintain the state at the start of storage until the rack and the side guard are stored in the inverted state, malfunction is prevented until the storage is completed in the inverted state, A malfunction can also be prevented when the rack returns to a horizontal state (in standby state).

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

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

  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 rotation drive link, and a brace 13 (side) that functions as a rotation driven link. And is formed in a triangular shape with a rigid structure when viewed from the front (that is, viewed from the width direction of the rack 12).

  The trolley 11 has a certain height along the column 1 erected in a cylindrical shape in the vertical direction, and is given traction force by the trolley lifting mechanism 20 between the lower position and the upper position of the column 1. The roller 111 (see FIG. 3) is disposed so as to be movable up and down (details will be described later). The carriage 11 is locked to the support column 1 at the lower position by the carriage 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) supported so as to be rotatable around a rotation shaft 120 (rotation axis) in the width direction with respect to the lower portion of the carriage 11 and extends in a cantilever shape in the longitudinal direction. An entrance / exit 123 for carrying in / out the bicycle BCL is formed at the (rear end). The rack turning mechanism 30 is provided with a moment about the rotating shaft 120 at the front end in the empty state, and is arranged so as to be rotatable from a horizontal state to an inverted state along the support column 1 with respect to the carriage 11 at the lower position ( The rotary slider crank mechanism 10 functions as a rotary drive link, which will be described in detail later. Further, the rack 12 can be locked to the 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 the left brace 13L and the right brace 13R (see FIGS. 3 and 4) have respective one end portions (upper end portions in FIGS. 1 to 4) with respect to the upper portion of the carriage 11. It is supported so as to be swingable around a swing shaft 130 (swing axis) in the width direction. On the other hand, the other end portions (lower end portions in FIGS. 1 to 4) of the left and right braces 13L and 13R are the midway portion of the rack 12 and the longitudinal direction of the plate-like member 122 fixed to the rear end portion (front end portion). A slide pin 131 (slider) that is slidably engaged and supported in an empty state at the lower position is formed with respect to the long hole 121 (guide portion) formed integrally with the rotary slider crank mechanism 10. Functions as a follower link. Further, the brace 13 is a pair of left and right braces spanned between the carriage 11 and the rack 12 in a diagonally crossed manner, and the lateral vibration (ie, the vibration of the bicycle BCL carried in and out of the horizontal rack 12 at the lower position) The rolling motion that is tilted to the left and right is blocked or suppressed, or the mounted bicycle BCL is prevented from falling. Further, the slide movement of the slide pin 131 with respect to the long hole 121 can be locked by the slider lock mechanism 50 (details will be described later).

  That is, in the lower position of the support column 1, the carriage 11, the rack 12 and the brace 13 have a pseudo right triangle-shaped rigid body structure in which the carriage 11 and the rack 12 intersect each other at a right angle when viewed from the front, and the brace 13 forms a hypotenuse. 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 almost right angles. In this way, the rotary slider crank mechanism 10 in which the rack 12 and the brace 13 perform a crank motion via the slide pin 131 is configured. Therefore, the slide pin 131 slides along the longitudinal direction in the long hole 121 in the empty state, and the rack 12 and the brace 13 are rotated upward with respect to the carriage 11 and stored in an inverted state along the column 1. In this inverted state, the rack 12 is stored so as to overlap the carriage 11 and the brace 13 in front view (see FIG. 7).

  By using the rotary slider crank mechanism 10 as described above, it is possible to realize a compact structure in the inverted storage structure of the bicycle parking machine 100. Further, the carriage 11, the rack 12 and the brace 13 are formed into a rigid triangular shape with each side having rigidity, and when the rack 12 and the brace 13 are stored in an inverted state, a bent portion or a slack portion does not occur.

  In the rotary slider crank mechanism 10 of the present embodiment, the rack 12 as the rotary drive link operates only in the range of a rotation angle of about 90 ° (1/4 rotation) from the horizontal state to the inverted state along the column 1 (FIG. 7). (Refer to), it can also be referred to as a “¼ rotation slider crank mechanism”.

  It should be noted that the slide pin 131 of the brace 13 is a rotational drive link in accordance with an example of a structure generally composed of a “rotating slider crank mechanism” (for example, a star-shaped rotary engine) or in light of the name of the mechanism. In the present embodiment, the rack 12 (the long hole 121) is used as the rotational drive link in consideration of the strength of the constituent members.

  The front wheel FW of the rack-mounted bicycle BCL (in the vicinity of the high-end side end of the brace 13 forming the oblique side (that is, close to the column 1) and between the wheel receiver 44 (described later) and the swing shaft 130 in a front view is provided. A tire guard 132 that holds a preceding carry-in wheel) stands upright from the brace 13 and can be raised and lowered. The tire guard 132 is formed in an inverted U shape that protrudes upward from one brace (eg, left brace 13L), bypasses the tire of the front wheel FW, and reaches the other brace (eg, right brace 13R), and is in a horizontal state at the lower position. When the bicycle BCL is carried into the rack 12, the both sides of the front wheel FW are straddled from above and held inside (see FIG. 11). Thus, when the bicycle BCL is carried into the rack 12, the tire guard 132 functions as a tire holder that holds the tire of the front wheel FW inside.

  An upright biasing spring 133 is installed between the brace 13 and the tire guard 132, and holds the tire guard 132 upright at all times with respect to the brace 13. In the process where the rack 12 and the brace 13 in the empty state are turned upward to reach the inverted state, the upper end portion of the tire guard 132 is in contact with the column 1 and resists the urging force of the standing urging spring 133 against the column 1. The posture is gradually changed so as to follow, and the rack 12 and the support column 1 are overlapped and stored in a front view (see FIG. 7). Thus, when the rack 12 in an empty state is stored in an 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 lifting gas spring 21, which forms the main part of the cart lifting mechanism 20, has a base end attached to the upper end in the column 1, and a distal end (lower end) of the piston rod 21 </ b> R protruding downward. A moving pulley 22 is attached to the vehicle. A fixed pulley 23 is also attached to the upper end portion of the column 1. One end of the connecting wire 24 is fixed at a predetermined position in the column 1, and the other end is fixed to the upper end surface of the carriage 11 after winding the moving pulley 22 and the fixed pulley 23 in this order. When the piston rod 21R is retracted (shrinked), the rack 12 is in a lower position together with the carriage 11, and is brought into an actual vehicle state by carrying in the bicycle BCL (see FIG. 11). The rack 12 rises to the upper position together with the carriage 11 by the protrusion (extension) of the piston rod 21R and stores the bicycle BCL (see FIG. 13).

  As shown in FIGS. 1 and 2, the rack turning mechanism 30 is mainly composed of a turning gas spring 31, and its base end is attached to the upper end of the carriage 11, while the tip of the piston rod 31 </ b> R is the rack 12. It is attached to the front end of the. The pushing force of the piston rod 31R generates a moment whose arm length is the horizontal distance between the tip end attachment position of the piston rod 31R and the rotation axis C120. When the piston rod 31R is retracted (reduced), the rack 12 is maintained in a horizontal state (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 column 1 (see FIG. 7).

  By the way, the raising / lowering gas spring 21 of the carriage raising / lowering mechanism 20 acts so that the carriage 11 is always pulled upward by the traction force corresponding to the total load of the carriage 11, the rack 12, the brace 13, and the rack-mounted bicycle BCL. Further, the turning gas spring 31 of the rack turning mechanism 30 acts so that the front end portion of the rack 12 is always stored in an inverted state with a moment corresponding to the total load of the rack 12 and the brace 13.

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

  Specifically, as shown in FIG. 3, a lock arm 41 is swingably attached to a 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. Thus, 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 column 1, and an arm biasing spring 43 is disposed between the carriage 11 and the upper end portion of the lock arm 41. The pawl 412 is always urged in the direction (front side) in which it engages with the arm engaging portion 2. In addition, a protrusion 411 protrudes downward from the rear portion of the locking claw 412.

  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 disposed so as to be able 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 disposed between the wheel receiver 44 and the rack 12. A 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 positioned in front. .

  As shown in FIG. 3, when the rack 12 is in an empty state, that is, when the front wheel FW is not placed on the wheel receiver 44, the wheel receiver 44 tilts backward and the extension rod 45 moves forward by the urging force of the rod urging spring 46. The part 451 is located in front of the protrusion 411. The lower end portion of the lock arm 41 is urged forward by the arm urging spring 43, and the locking claw 412 is engaged with the arm engagement portion 2 and locked. That is, the bogie lock mechanism 40 is locked so that the bogie 11 cannot be raised and lowered with respect to the column 1.

  On the other hand, as shown in FIG. 12, when the rack 12 is in an 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. Therefore, the hook portion 451 engages with the protrusion 411 and pulls backward. The locking claw 412 of the lock arm 41 rotates rearward against the total biasing force of the arm biasing spring 43 and the rod biasing spring 46, and the engagement with the arm engaging portion 2 is released. That is, the bogie lock mechanism 40 releases the lock so that the bogie 11 can be moved up and down with respect to the support column 1.

  As shown in FIG. 9, when the rack 12 is housed in an inverted state, that is, when the rack 12 rotates around the rotation shaft 120, the hooking portion 451 gradually turns away from the outside of the protrusion 411. . The lower end portion of the lock arm 41 is urged forward by the arm urging spring 43, and the locking claw 412 is engaged with the arm engagement portion 2 and locked. That is, the bogie lock mechanism 40 is locked so that the bogie 11 cannot be raised and lowered with respect to the column 1.

  1 and 2, the slider lock mechanism 50 prevents the slide pin 131 from sliding with respect to the long hole 121 when the carriage 11 is in the lower position and the rack 12 is in a horizontal state. The rack 12 and the brace 13 are locked so that the upward rotation of the rack 12 and the brace 13 based on the moment by the rotating gas spring 31 is disabled (see FIG. 4). On the other hand, the slider lock mechanism 50 releases the lock so that the rack 12 and the brace 13 can be turned upward by allowing the slide pin 131 to slide (see FIG. 6).

  In addition, the rack lock mechanism 60 has a lock operation mode (see FIG. 4 or FIG. 15) in which the rack 12 is locked to the support 1 at the lower position or the upper position so that the rack 12 cannot be moved, and the rack lock mechanism 60 moves by releasing the lock. The mode is switched to the unlocking mode (see FIG. 6). Switching between the lock operation mode and the lock release mode in the rack lock mechanism 60 is based on the operation of the operation member 64 that is disposed at the entrance 123 of the rack 12 and also serves as an empty vehicle state detection unit and an artificial operation unit. And simultaneously executed in conjunction with the locking operation and unlocking of the slider lock mechanism 50 (see FIGS. 4 and 6).

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

  A support plate 124 is fixed to the rack 12, and one end of a rotation lock plate 51 is provided to be rotatable about a rotation shaft 52 in the width direction disposed on the support plate 124. A lock claw 511 including a notch opening downward is formed at the other end of the rotation lock plate 51, and the notch of the lock claw 511 can be fitted to the slide pin 131 from above. In the middle of the rotation shaft 52 and the lock claw 511, an inclined long hole 513 is formed in a direction intersecting with the long axis arrangement direction (that is, the horizontal direction) of the long hole 121, and protrudes in the width direction from the connecting rod 63. The formed operation pin 53 is inserted into the inclined long hole 513. A slope portion 512 that is inclined in a direction different from the inclined long hole 513 is formed at the tip of the lock claw 511 of the rotation lock plate 51.

  As shown in FIG. 4, when the carriage 11 is in the lower position and the rack 12 is in a horizontal state, the rack stopper 61 is a stopper biasing spring when the operating member 64 is not operated and the connecting rod 63 is not pulled. It is urged forward by 62 and is engaged with the lower side after riding on the lower engaging portion 4. That is, the rack lock mechanism 60 is locked so that the rack 12 is locked to the support column 1 and cannot move. Further, since the operation pin 53 is on the front end side of the inclined long 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 brace 13 is locked so that it cannot be turned upward. That is, the slider lock mechanism 50 operates so as to prohibit the sliding movement of the slide pin 131 and to make the inverted storage impossible.

  On the other hand, as shown in FIG. 6, when the cart 11 is in the lower position and the rack 12 is in the horizontal state, when the actuating member 64 is actuated and the connecting rod 63 is pulled, the rack stopper 61 is a stopper biasing spring. It moves to the rear side against 62 and is unlocked from the lower engaging portion 4. That is, the rack lock mechanism 60 unlocks the rack 12 so that the rack 12 is unlocked so as to be movable. Further, the operation pin 53 moves to the rear side of the inclined long hole 513 to rotate the rotation lock plate 51 upward, the fitting of the notch of the lock claw 511 and the slide pin 131 is released, and the slide movement is permitted. The lock is released so that the rack 12 and the brace 13 can be turned upward. In other words, the slider lock mechanism 50 permits the slide movement of the slide pin 131 and releases the lock so that it can be inverted and stored.

  When the rack 12 is stored in an inverted state, that is, when the rack 12 rotates around the rotation shaft 120, the rack stopper 61 gradually moves away from the lower stage engaging portion 4. That is, the rack lock mechanism 60 maintains the unlocking so that the rack 12 can be moved by unlocking the rack 12 with respect to the column 1. Further, as shown in FIG. 8, the slide pin 131 can be slid in the elongated hole 121 regardless of the rotation lock plate 51. That is, the slider lock mechanism 50 permits the slide movement of the slide pin 131 and maintains the unlocking 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 opposite direction to the storage in the inverted state, and the notch of the lock claw 511 slides. The slide movement is locked by fitting with the pin 131. At that time, when the slide pin 131 slides in the long hole 121 in the direction opposite to the arrow in FIG. 8, the slide pin 131 enters the inclined surface 512 of the lock claw 511 and rotates around the rotation shaft 52. 51 is turned upward, and the notch of the lock claw 511 is fitted to the slide pin 131 to lock the slide movement.

  In this way, when the carriage 11 is in the lower position and the horizontal rack 12 becomes empty as the bicycle BCL is carried out (see FIG. 5), the carriage lock mechanism 40 moves the carriage 11 up and down with respect to the column 1. The locking operation is performed so that it cannot be performed (see FIG. 3), the slider locking mechanism 50 permits the sliding movement of the slide pin 131 with respect to the long hole 121, and the rack locking mechanism 60 unlocks the rack 12 with respect to the support column 1. The rack 12 and the brace 13 are rotated upward with respect to the carriage 11 based on the moment by the rotating gas spring 31 by simultaneously releasing the lock in conjunction with each other so as to enable the movement (see FIG. 6). And stored in an inverted state along the 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 operation member 64, the slide lock 131 is locked to the long hole 121 by the slider lock mechanism 50, and the rack lock mechanism 60 is used. The locking operation of the rack 12 with respect to the column 1 is performed in conjunction with each other (see FIG. 10).

  As described above, the rack 12 and the brace 13 that have been unloaded from the bicycle BCL and are in an empty state are not bent or slacked until they are stored in an inverted state, and the rotation drive link constituting the rotary slider crank mechanism 10 and A rigid structure can be maintained as a rotary driven link. Therefore, it is possible to provide a bicycle parking machine 100 that has a strong rack storage structure that is excellent in strength and durability, and that can safely and securely store and manage various types of bicycles from light weight to heavy weight.

  Further, the rack 12 that has been unloaded from the bicycle BCL at the lower position is automatically stored in an inverted state, and the rack 12 that has been loaded into the rack 12 and is in the actual vehicle state at the lower position is the upper stage. Stored and managed in position. Therefore, in the inverted storage type bicycle parking apparatus 100, both the work for carrying out the bicycle BCL and the work for carrying it in are performed at the lower position, so that the work load is reduced and erroneous operations are less likely to occur.

  Next, an outline of the operation of the bicycle parking apparatus 100 described above will be described in the order of operations.
