Description

bicycle parking device

Technical Field

The invention relates to a bicycle parking device.

Background

In a bicycle parking device having a vertically ascending/descending type frame, a bicycle is carried into the frame at a lower position of a pillar, and the frame in a loaded state is stored and managed at an upper position. As a storage method of a frame that is unloaded to bring a bicycle, there are known a type that is stored in a horizontal state in a sliding manner (i.e., horizontal storage) at an upper position, and a type that is stored in a state that is rotated about a base end portion and is jumped up (i.e., inverted storage). Patent document 1 shows the latter jump-up storage type, and compared with the former slide storage type, the amount of projection of the vehicle body frame at the time of storage can be reduced to save space.

However, in patent document 1, the height position of the rack (frame) is different between when the bicycle is carried out and when the bicycle is carried in. That is, by pressing down the stand to the bicycle parking posture position below the parking standby posture position, and only when the stand is carried out after the operation of releasing the rotation lock of the stand (that is, the operation of releasing the rotation lock of the stand by switching the switching mechanism to the non-engagement position by the operation of moving from the upper bicycle parking posture position to the lower bicycle parking posture position) is performed, the empty stand (that is, in the unloaded state) can be automatically stored in the jumping posture position. On the other hand, after the parking posture position has passed from the jumping posture position, the bicycle is carried in only when the rotation locking operation of the vacant stand is performed at the parking standby posture position (that is, the operation of returning from the lower bicycle parking posture position to the upper bicycle parking posture position enables the switching mechanism to be switched to the engagement position and the rotation locking operation of the stand is performed). In this way, when the bicycle is carried in and out at the lower parking posture position and the bicycle is carried in and out at the upper parking standby posture position, the operation is complicated, the work load is increased, and the erroneous operation is likely to occur, as compared with the case where the bicycle is carried in and out at a constant height position. In particular, when the automatic storage to the jumping posture position of the stand is performed in response to the carrying-out operation of the bicycle, and when the ascending movement of the stand is allowed in response to the carrying-in operation of the bicycle, there is a possibility that a problem may occur in the safety of the operation.

Problems to be solved by the invention

The present invention addresses the problem of providing a bicycle parking device that performs, at the same height position, the operation of carrying out a bicycle to automatically store a frame in an inverted state and the operation of carrying in the bicycle to store and manage the frame, and that is simple and safe and is less likely to cause erroneous operation.

Means for solving the problems and effects of the invention

In order to solve the above problem, a bicycle parking device according to the present invention includes:

a base (e.g., a carriage) that is vertically disposed along a column in a cylindrical manner and is configured to be movable up and down between a lower position and an upper position of the column by application of a traction force;

A frame that is supported rotatably about a rotation axis in a width direction at a base end portion thereof with respect to a lower portion of the base body, that extends in a cantilever shape in a longitudinal direction (for example, in a groove shape), that has an entrance for carrying in and out a bicycle formed at a terminal end thereof, that is rotatable from a horizontal state to an inverted state along the column with respect to the base body at the lower position by a moment about the rotation axis applied to the base end portion in an unloaded state in which the bicycle is not mounted, and that is liftable together with the base body between the lower position and an upper position in a loaded state in which the bicycle is mounted;

Side guards (e.g., support members) which are disposed on both sides of the frame in the width direction and have one end supported so as to be swingable about a swing axis in the width direction with respect to the upper portion of the base body, and which have the other end formed with a slider (specifically, a slide pin or a slide block) which is slidably engaged and supported with a guide portion (specifically, a long hole or a guide rail) integrally formed (near the terminal end portion) in the middle portion of the frame in the longitudinal direction, so that the side guards are bridged between the base body and the frame, in order to prevent or suppress yaw motion which is lateral swing vibration (i.e., lateral deflection) of the bicycle carried in and out to the frame in the horizontal state at the lower floor position;

A lower-stage stopper mechanism that performs a locking operation so that the base cannot be raised and lowered by the traction force with respect to the column in the unloaded state when the base is located at the lower-stage position, and performs a lock release so that the base can be raised and lowered in the loaded state;

A rotation stop mechanism that prohibits sliding movement of the slider with respect to the guide portion when the base is in the lower position and the vehicle frame is in the horizontal state, and that performs a locking operation so that upward rotation of the vehicle frame and the side guard based on the moment with respect to the base is not possible, and that permits sliding movement so that the locking is released so that upward rotation is possible; and

A movement stopper mechanism that switches between a lock operation mode in which the body frame is locked to the support column so as not to move and a lock release mode in which the body frame is released from the locking so as to move, at the lower stage position or the upper stage position,

when the base is in the lower position and the horizontal frame is in the unloaded state as the bicycle is carried out, the lower stopper mechanism performs a locking operation so that the base cannot be raised and lowered with respect to the column, the pivot stopper mechanism allows the slider to slidably move with respect to the guide portion, and the movement stopper mechanism can be interlocked (for example, simultaneously) to release the locking so that the frame is moved while releasing the locking with respect to the column, so that the frame and the side guard are rotated upward with respect to the base based on the moment and stored in an inverted state along the column.

In this way, the frame that is unloaded by carrying the bicycle out of the frame at the lower position is automatically stored in the inverted state, and the frame that is loaded with the bicycle into the frame at the lower position is stored and managed at the upper position. Therefore, in the inverted storage type bicycle parking device, since the carrying-out operation and the carrying-in operation of the bicycle are performed at the lower level position, the operation load is reduced, and the occurrence of the erroneous operation is less likely.

In addition, the lower stopper mechanism locks the base body to the pillar in the vertical direction in association with the unloading operation of the bicycle from the lower position, and the unlocking operation of the slider with respect to the guide portion by the rotation stopper mechanism and the unlocking operation of the frame with respect to the pillar by the movement stopper mechanism are performed in linkage with each other. That is, when the bicycle is carried out from the frame at the lower position, the base can be fixed to the pillar, and the relative movement between (the guide portion of) the frame and (the slider of) the side guard and the locking of the frame to the pillar can be released.

When the carriage is returned from the inverted state to the horizontal state, the locking operation of the slider with respect to the guide portion by the turning stop mechanism and the locking operation of the carriage with respect to the stay by the movement stop mechanism can be performed in conjunction with each other. Therefore, even when the lifting lock of the base body with respect to the support column is released by the lower stopper mechanism when the bicycle is carried into the frame at the lower position, the frame is locked to the support column by the locking operation of the movement stopper mechanism, and therefore, the risk of the frame being in a loaded state being accidentally lifted can be avoided. In this way, by providing the rotation stopper mechanism and the movement stopper mechanism to perform the unlocking or locking operation in conjunction with each other, the safety of the bicycle in the carrying-out operation and the carrying-in operation can be improved in the frame at the lower position.

However, the application of the traction force to the base (means) functions to always lift the base upward by the traction force corresponding to the total load of the base, the frame, the side guards, and the frame-mounted bicycle. Further, the application of the moment to the base end portion of the frame (mechanism) functions to always rotate the frame in an inverted state and store it by the moment corresponding to the total load of the frame and the side guards.

the side guards are so-called diagonal braces, which are installed on both sides of the frame in the width direction of the vehicle frame so as to prevent the bicycle from falling down, and are also collectively called "braces".

In addition, in the lower position, the base body, the frame, and the side guard are formed in a triangular shape having a rigid structure when viewed in the width direction, and in the unloaded state, when the rotary slide crank mechanism in which the frame and the side guard are cranked via the slider is formed, the frame and the side guard in the unloaded state from which the bicycle is carried out can be held as the rotary drive link and the rotary driven link forming the rotary slide crank mechanism without being bent or loosened until the frame and the side guard are stored in the inverted state. Therefore, the bicycle parking device can be provided with a strong frame storage structure with excellent strength and durability, and can safely and reliably store and manage various bicycles from light weight to heavy weight.

The "triangular shape of rigid body structure" means that the "base, the frame, and the side guard plates, which are components of the slider crank mechanism, are formed into a strong triangular shape having rigidity on each side, and the bent portions and the slack portions are not generated when the frame and the side guard plates are stored in the inverted state". In the rotary slide crank mechanism, the "guide portion" may be formed by a long hole, the "slider" may be formed by a slide pin, the "guide portion" may be formed by a guide rail, and the "slider" may be formed by a slide block. In the above-described "rotary slider crank mechanism", the frame as the rotary drive link operates only in a range of a rotation angle (1/4 rotation) of about 90 ° from the horizontal state to the inverted state along the column, and therefore, may be referred to as a "1/4 rotary slider crank mechanism".

The rotation stopper mechanism and the movement stopper mechanism are unlocked only when the base is located at the lower position and the vehicle frame is in the horizontal state and the lower stopper mechanism performs the locking operation.

In this way, since it is necessary to fix the base to the pillar as a locking operation of the lower stopper mechanism in order to store the vehicle body frame and the side guard in the inverted state, safety is ensured and erroneous operation is less likely to occur.

Specifically, when the bicycle is carried out from the loaded frame to the unloaded state, the rotation stopper mechanism and the movement stopper mechanism are unlocked after the lower stopper mechanism performs the locking operation.

In this way, by giving priority to the locking operation of the lower stopper mechanism, the raising and lowering lock operation of the base body with respect to the column is performed prior to the unlocking of the slider with respect to the guide portion (turning stopper mechanism) and the unlocking of the locking of the carriage with respect to the column (movement stopper mechanism). Thus, the frame and the side guard plate are rotated upward with respect to the base fixed to the pillar, and are stored in an inverted state with a stable track.

more specifically, the frame is provided with a first detecting means for detecting that the bicycle in the intermediate state is unloaded in order to lock the lower stopper mechanism, and a second detecting means for detecting that the bicycle in the finished state is unloaded in order to unlock the swing stopper mechanism and the swing stopper mechanism at the same time.

By providing such first and second detection means, the operation timing of the lower stopper mechanism is prioritized, and the operation timings of the rotational stopper mechanism and the movement stopper mechanism can be synchronized easily.

For example, when the subsequent carrying-out wheel (for example, the front wheel) is retreated from the wheel support (the first detection means), the carrying-out intermediate state (i.e., the unloaded state) is detected, the lower stopper mechanism performs the locking operation, and then, when the subsequent carrying-out wheel (for example, the front wheel) is carried out (passed) from the operation member (the second detection means) of the doorway, the carrying-out end state (i.e., the completely unloaded state) is detected, and the locking of the rotation stopper mechanism and the movement stopper mechanism is released.

when the frame and the side guard are stored in the inverted state, the lower stopper mechanism maintains the locking operation, and the rotation stopper mechanism and the movement stopper mechanism maintain the unlocking.

Since the lower stopper mechanism, the rotation stopper mechanism, and the movement stopper mechanism maintain the state at the start of storage until the carriage and the side guard are stored in the inverted state, the malfunction is prevented until the storage in the inverted state is completed, and the malfunction can be prevented even when the carriage returns to the horizontal state (the carry-in standby state).

Detailed Description

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

The inverted storage type bicycle parking device 100 shown in fig. 1 includes a rotary slider crank mechanism 10 as a basic structure for realizing a function of an idle-load frame 12 (see fig. 7) for inverted storage, that is, storing a bicycle BCL in an inverted state, a carriage lifting mechanism 20 (traction force applying mechanism) and a frame turning mechanism 30 (moment applying mechanism) as means for driving the respective portions, and a carriage locking mechanism 40 (lower stopper mechanism), a slider locking mechanism 50 (rotation stopper mechanism), and a frame locking mechanism 60 (movement stopper mechanism) as means for restricting operations of the respective portions.

As shown in fig. 1 and 2, the rotary slider crank mechanism 10 includes a bogie 11 (base) functioning as a fixed link, a frame 12 functioning as a rotary drive link, and a brace 13 (skirt guard) functioning as a rotary driven link, and is formed in a triangular shape having a rigid structure when viewed from the front (i.e., when viewed in the width direction of the frame 12).

The carriage 11 has a constant height along the column 1 vertically erected in a cylindrical shape, and is disposed to be movable up and down between a lower position and an upper position of the column 1 by a roller 111 (described later in detail) by applying a traction force by a carriage lifting mechanism 20. The carriage 11 is locked to the column 1 at a lower position by a carriage lock mechanism 40 (described later in detail), and functions as a fixed link in the rotary slider crank mechanism 10.

The front end portion (base end portion) of the frame 12 is supported rotatably about a rotating shaft 120 (rotation axis) in the width direction with respect to the lower portion of the bogie 11, extends in a groove shape in the longitudinal direction in a cantilever manner, and has an access opening 123 for carrying in and out the bicycle BCL at a terminal end (rear end). The frame turning mechanism 30 is disposed so that the front end portion thereof is given a moment about the rotary shaft 120 in the unloaded state and can be turned from a horizontal state to an inverted state along the column 1 with respect to the bogie 11 located at the lower stage (described in detail later), and functions as a turning drive link in the slider-crank mechanism 10. The frame 12 can be locked to the pillar 1 by a frame lock mechanism 60 (described in detail later).

The stay 13 is disposed in a pair on both sides in the width direction of the vehicle body frame 12, and one end (upper end in fig. 1 to 4) of each of the left stay 13L and the right stay 13R (see fig. 3 and 4) is supported to be swingable about a swing shaft 130 (swing axis) in the width direction with respect to the upper portion of the bogie 11. On the other hand, the other end portions (lower end portions in fig. 1 to 4) of the left and right stays 13L and 13R are formed as long holes 121 (guide portions) formed integrally in the longitudinal direction with respect to a plate-like member 122 fixed along the middle portion of the frame 12 and near the rear end portion (terminal end portion), and slide pins 131 (sliders) engaged and supported in a slidable manner in a no-load state at the lower position function as rotationally driven links in the rotational slider crank mechanism 10. The stay 13 is a pair of left and right diagonal stays that are installed between the bogie 11 and the frame 12 in an obliquely intersecting manner, and prevents or suppresses yaw motion that is yaw vibration (i.e., lateral deflection) of the bicycle BCL of the frame 12 that is carried in and out to the horizontal state at the lower position, or prevents the bicycle BCL from falling. Further, the slider lock mechanism 50 can lock the sliding movement of the slide pin 131 with respect to the long hole 121 (described in detail later).

That is, at the lower position of the pillar 1, the bogie 11, the frame 12, and the strut 13 have a rigid structure of a substantially right triangle in which the bogie 11 and the frame 12 intersect at substantially right angles in a front view and the strut 13 forms a hypotenuse. Strictly speaking, 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 form an approximately right triangle intersecting at substantially right angles. Thus, the rotary-block crank mechanism 10 is constructed in which the frame 12 and the stay 13 are cranked via the slide pin 131. Therefore, in the unloaded state, the slide pin 131 slides in the longitudinal direction in the long hole 121, and the vehicle frame 12 and the stay 13 rotate upward relative to the bogie 11 and are stored in an inverted state along the strut 1. In this inverted state, the frame 12 is housed in a state of being overlapped with the carriage 11 and the stay 13 in a front view.

By using such a rotary slider crank mechanism 10, the inverted storage structure of the bicycle parking device 100 can be made compact. Further, since the bogie 11, the frame 12, and the stay 13 are formed into a strong triangle having rigidity on each side, the bent portion and the slack portion are not generated when the frame 12 and the stay 13 are stored in the inverted state.

In the rotary slide crank mechanism 10 of the present embodiment, the body frame 12 as the rotary drive link operates only in a range of a rotation angle (1/4 rotation) of about 90 ° from the horizontal state to the inverted state along the column 1 (see fig. 7), and therefore, may be referred to as a "1/4 rotary slide crank mechanism".

further, although an example of a structure constituted by a "rotary slider crank mechanism" (for example, a star rotary engine) is generally described, in contrast to the name of the mechanism, the slide pin 131 of the stay 13 is generally made to be a rotation driving link (active member), but in the present embodiment, (the long hole 121 of) the body frame 12 is made to be a rotation driving link in consideration of the strength of the constituent members.

A tire protector 132 for holding a front wheel FW (preceding carrying-in wheel) of the frame-mounted bicycle BCL is provided upright from the stay 13 and is undulatable between a wheel stay 44 (described later) and the swing shaft 130 in front view near a high-position side end of the stay 13 (i.e., near the pillar 1). The tire protector 132 is formed into an inverted U shape that protrudes upward from one stay (for example, the left stay 13L), passes over the tire of the front wheel FW, reaches the other stay (for example, the right stay 13R), and is held inside across both sides of the front wheel FW from above when the bicycle BCL is loaded into the horizontal frame 12 at the lower position (see fig. 11). When the bicycle BCL is carried into the body frame 12 in this way, the tire shield 132 functions as a tire holder that holds the tire of the front wheel FW inside.

The upright biasing spring 133 is disposed between the stay 13 and the tire guard 132, and maintains the tire guard 132 in an upright posture with respect to the stay 13. In the process of turning the vehicle body frame 12 and the stay 13 in the unloaded state upward to reach the inverted state, the upper end portion of the tire guard 132 comes into contact with the pillar 1, and the posture thereof is gradually changed along the pillar 1 against the biasing force of the rising biasing spring 133, and the tire guard is stored while being overlapped with the vehicle body frame 12 in a front view (see fig. 7). When the vehicle body frame 12 in the unloaded state is stored in the inverted state, the tire guard 132 functions as a storage guide which is brought into contact with the pillar 1 and is gradually folded and stored.

Returning to fig. 1, a base end portion of a pneumatic spring 21 for lifting, which constitutes a main portion of the carriage lifting mechanism 20, is attached to an upper end portion inside the column 1, and a movable sheave 22 is attached to an end portion (lower end portion) of a piston rod 21R that protrudes downward. Further, a fixed pulley 23 is also attached to an upper end portion in the column 1. One end of the connecting wire 24 is fixed to a predetermined position in the column 1, and after winding the movable pulley 22 and the fixed pulley 23 in this order, the other end is fixed to the upper end surface of the carriage 11. When the piston rod 21R retracts, the frame 12 is positioned at the lower position together with the carriage 11, and the bicycle BCL is loaded (see fig. 11). By the projection (extension) of the piston rod 21R, the frame 12 is raised to the upper position together with the carriage 11, and the bicycle BCL is stored (see fig. 13).

As shown in fig. 1 and 2, the frame turning mechanism 30 is mainly composed of a turning pneumatic spring 31, and has a base end portion attached to an upper end portion of the bogie 11, and a tip end portion of a piston rod 31R attached to a tip end portion of the frame 12. The pushing force of the piston rod 31R generates a moment having a horizontal distance between the mounting position of the terminal end of the piston rod 31R and the rotation axis C120 as the arm length. When the piston rod 31R retreats (contracts), the vehicle body frame 12 is maintained in a horizontal state (see fig. 5). On the other hand, when the piston rod 31R is projected (extended), the frame 12 and the stay 13 are rotated upward relative to the bogie 11 and stored in an inverted state along the column 1 (see fig. 7).

However, the pneumatic spring 21 for lifting and lowering the carriage lifting and lowering mechanism 20 functions to always pull up the carriage 11 upward by a traction force corresponding to the total load of the carriage 11, the frame 12, the stay 13, and the frame-mounted bicycle BCL. The turning pneumatic spring 31 of the frame turning mechanism 30 functions to always store the front end portion of the frame 12 in an inverted state by a moment corresponding to the total load of the frame 12 and the strut member 13.

The carriage lock mechanism 40 shown in fig. 1 and 2 functions in the following manner when the carriage 11 is located at the lower position: the locking operation is performed so that the carriage 11 cannot be raised and lowered by the traction force of the lifting pneumatic spring 21 with respect to the column 1 in the unloaded state (see fig. 3), and the locking is released so that the carriage can be raised and lowered in the loaded state (see fig. 12).

Specifically, as shown in fig. 3, the lock arm 41 is swingably attached to a support shaft 42 disposed in the width direction of the carriage 11, and a lower end portion of the lock arm 41 is bent forward in an L-shape to form a locking claw 412. The locking claw 412 can be engaged with the arm engagement 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, and the locking claw 412 is constantly biased in the direction (forward side) of engagement with the arm engagement portion 2. Further, a projection 411 is formed to project downward from the rear portion of the locking claw 412.

Further, a wheel stay 44 for receiving a front wheel FW (preceding carrying-in wheel) of the carrying-in bicycle BCL is disposed near a front end portion of the frame 12 so as to be swingable forward and backward. The wheel stay 44 is connected to an extension rod 45 extending in the front-rear direction, and the extension rod 45 is always biased forward by a rod biasing spring 46 disposed between the wheel stay 44 and the frame 12. The distal 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 and is located forward of the protrusion 411 formed at the lower end portion of the lock arm 41.

As shown in fig. 3, when the vehicle body frame 12 is in an unloaded state, that is, when the front wheel FW is not mounted on the wheel stay 44, the wheel stay 44 is tilted backward by the biasing force of the lever biasing spring 46, and the extension lever 45 is advanced, so that the hook portion 451 is positioned forward of the protrusion 411. The lower end portion of the lock arm 41 is biased forward by the arm biasing spring 43, and the locking claw 412 is engaged with the arm engaging portion 2 and locked. That is, the carriage lock mechanism 40 performs a locking operation so that the carriage 11 cannot be raised and lowered with respect to the column 1.

On the other hand, as shown in fig. 12, when the front wheel FW is mounted on the wheel stay 44, which is a fully loaded state of the vehicle body frame 12, the wheel stay 44 is tilted forward against the biasing force of the lever biasing spring 46, and the extension lever 45 is retracted, so that the hook portion 451 engages with the protrusion 411 and is pulled rearward. The locking claw 412 of the lock arm 41 is turned rearward against the total urging force of the arm urging spring 43 and the lever urging spring 46, and releases the engagement with the arm engaging portion 2. That is, the carriage lock mechanism 40 is unlocked to enable the carriage 11 to be raised and lowered with respect to the column 1.

As shown in fig. 9, when the vehicle body frame 12 is stored in the inverted state, that is, when the vehicle body frame 12 rotates about the swing shaft 130, the hook portion 451 gradually separates from the protrusion 411. The lower end portion of the lock arm 41 is biased forward by the arm biasing spring 43, and the locking claw 412 is engaged with the arm engaging portion 2 and locked. That is, the carriage lock mechanism 40 performs a locking operation so that the carriage 11 cannot be raised and lowered with respect to the column 1.

Returning to fig. 1 and 2, when the carriage 11 is in the lower position and the frame 12 is in the horizontal state, the slider lock mechanism 50 performs a locking operation by prohibiting the sliding movement of the slide pin 131 with respect to the elongated hole 121 so that the upward rotation of the frame 12 and the stay 13 based on the moment of the turning air pressure spring 31 with respect to the carriage 11 is not performed (see fig. 4). On the other hand, the slider lock mechanism 50 releases the lock by allowing the sliding movement of the slide pin 131 so that the carriage 12 and the stay 13 can be pivoted upward (see fig. 6).

The carriage lock mechanism 60 is switched between a lock operation mode (see fig. 4 or 15) in which the carriage 12 is locked to the strut 1 and cannot move and a lock release mode (see fig. 6) in which the locking is released and the movement is possible, in the lower-stage position or the upper-stage position. Switching between the locking operation mode and the unlocking mode in the carriage locking mechanism 60 is performed based on the operation of the operating member 64 which is disposed at the entrance 123 of the carriage 12 and serves as both the idle state detecting means and the manual operation means, and is simultaneously performed in conjunction with the locking operation and the unlocking of the slider locking mechanism 50 (see fig. 4 and 6).

Specifically, as shown in fig. 4, a lower engagement portion 4 whose projecting amount toward the rear side becomes larger as it goes downward is formed at a lower position of the pillar 1, and a frame stopper 61 that is constantly biased toward the pillar side (forward side) by a stopper biasing spring 62 is provided below the frame 12. The frame stopper 61 is coupled to an operating member 64 provided at the doorway 123 via a coupling rod 63 extending in the longitudinal direction of the frame 12, the operating member serving as both a detection mechanism for an empty load state and an artificial operation mechanism.

The support plate 124 is fixed to the vehicle body frame 12, and one end of the rotation lock plate 51 is provided to be rotatable about the rotation shaft 52 disposed in the width direction of the support plate 124. A locking pawl 511 having a cutout that opens downward is formed at the other end of the rotational lock plate 51, and the cutout of the locking pawl 511 can be fitted to the slide pin 131 from above. An inclined long hole 513 is formed in a direction intersecting the longitudinal direction (i.e., the horizontal direction) of the long hole 121 between the rotating shaft 52 and the lock pawl 511, and the operation pin 53 formed to protrude in the width direction from the connecting rod 63 is inserted into the inclined long hole 513. A slope portion 512 inclined in a direction different from the direction of the inclined long hole 513 is formed at the terminal end portion of the rotary lock plate 51 closer to the terminal end than the lock pawl 511.

as shown in fig. 4, when the operating member 64 is not operated and the connecting rod 63 is not pulled when the carriage 11 is at the lower position and the frame 12 is in the horizontal state, the frame stopper 61 is biased forward by the stopper biasing spring 62 and is locked in a state of ascending the lower engaging portion 4. That is, the frame lock mechanism 60 performs a locking operation so that the frame 12 is locked to the pillar 1 so as not to move. Further, since the operation pin 53 is positioned 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 pawl 511 is fitted into the slide pin 131 to lock the sliding movement, and the lock operation is performed so that the frame 12 and the stay 13 cannot rotate upward. That is, the slider lock mechanism 50 prohibits the sliding movement of the slide pin 131, and performs the locking operation so that the inverted storage is impossible.

On the other hand, as shown in fig. 6, when the operating member 64 is operated to pull the connecting rod 63 when the carriage 11 is at the lower position and the frame 12 is in the horizontal state, the frame stopper 61 moves rearward against the stopper biasing spring 62, and the engagement with the lower engaging portion 4 is released. That is, the carriage lock mechanism 60 is unlocked so as to be movable to release the locking of the carriage 12 with respect to the pillar 1. Further, the operation pin 53 moves to the rear side of the inclined long hole 513, the rotation lock plate 51 is rotated upward, the fitting between the notch of the lock pawl 511 and the slide pin 131 is released to allow the sliding movement, and the lock is released so that the upward rotation of the body frame 12 and the stay 13 is possible. That is, the slider lock mechanism 50 allows the slide movement of the slide pin 131 and releases the lock so as to be able to be stored in an inverted state.

When the frame 12 is stored in the inverted state, that is, when the frame 12 rotates about the swing shaft 130, the frame stopper 61 gradually moves away from the lower engagement portion 4. That is, the carriage lock mechanism 60 is unlocked so as to be movable to release the locking of the carriage 12 with respect to the pillar 1. As shown in fig. 8, the slide pin 131 is slidably movable in the elongated hole 121 regardless of the rotation of the lock plate 51. That is, the slider lock mechanism 50 allows the slide movement of the slide pin 131 and releases the lock so as to be able to be stored in an inverted state.

When the carriage 12 is returned from the inverted state to the horizontal state, the carriage stopper 61 is also locked to the lower engaging portion 4 by moving in the direction opposite to the direction of storage in the inverted state, and the notch of the lock pawl 511 is fitted to the slide pin 131 to lock the sliding movement. At this time, when the slide pin 131 slides in the direction opposite to the arrow in fig. 8 into the long hole 121, the slide pin 131 enters the inclined surface portion 512 of the lock pawl 511, the rotation lock plate 51 is rotated upward about the rotation shaft 52, and the notch of the lock pawl 511 is fitted into the slide pin 131 to lock the sliding movement.

As described above, when the frame 12, which is in a horizontal state with the carriage 11 positioned at the lower position and the bicycle BCL carried out, is in an unloaded state (see fig. 5), the carriage lock mechanism 40 performs a locking operation so that the carriage 11 cannot be lifted relative to the support column 1 (see fig. 3), the slider lock mechanism 50 allows the sliding movement of the slide pin 131 relative to the elongated hole 121, the frame lock mechanism 60 can move by releasing the locking of the frame 12 relative to the support column 1, and the locking is simultaneously released in conjunction with each other (see fig. 6), whereby the frame 12 and the support 13 are rotated upward relative to the carriage 11 and stored in an inverted state along the support column 1 (see fig. 7) based on the moment of the turning pneumatic spring 31.

When the vehicle body frame 12 is returned from the inverted state to the horizontal state by the manual operation of the operating member 64, the locking operation of the slide pin 131 with respect to the elongated hole 121 by the slide lock mechanism 50 and the locking operation of the vehicle body frame 12 with respect to the stay 1 by the vehicle body frame lock mechanism 60 are performed in conjunction with each other (see fig. 10).

In this way, the frame 12 and the stay 13, from which the bicycle BCL is carried out and brought into an unloaded state, are not bent or loosened until being stored in an inverted state, and a rigid structure can be maintained as the rotary drive link and the rotary driven link that constitute the rotary slider crank mechanism 10. Therefore, the bicycle parking device 100 can be provided with a strong frame storage structure having excellent strength and durability, and can safely and reliably store and manage various bicycles ranging from lightweight to heavy-weight.

Further, the frame 12, which is unloaded by carrying the bicycle BCL out of the frame 12 at the lower position, is automatically stored in the inverted state, and the frame 12, which is loaded by carrying the bicycle BCL into the frame 12 at the lower position, is stored and managed at the upper position. Therefore, in the inverted storage type bicycle parking device 100, since the carrying-out operation and the carrying-in operation of the bicycle BCL are performed at the lower level, the operation load is reduced, and the occurrence of the erroneous operation is less likely.

Next, the operation of the bicycle parking device 100 described above will be schematically described in the order of operation.

< lower floor position, midway when the bicycle is carried out from the horizontal frame > (fig. 1, 3 and 4)

As shown in fig. 1, the front wheel FW is located rearward of the wheel support portion 44 and forward of the operating member 64, and the bicycle BCL is in the middle of being carried out. The wheel stay 44 (first detection means) detects the unloaded state, i.e., the end of the removal, and the locking claw 412 is engaged with the arm engagement portion 2, so that the carriage 11 is locked by the column 1 (fig. 3). Since the front wheel FW is not in contact with the operating member 64 (second detection means) and is not detected as the end of the carrying-out (unloaded state), the frame stopper 61 is caught by the lower engaging portion 4, and the frame 12 is locked to the stay 1. Further, the notch of the lock pawl 511 is fitted to the slide pin 131 to lock the sliding movement, and therefore, the inverted storage of the vehicle body frame 12 is prevented (fig. 4).

< end of carrying out bicycle from frame > (fig. 5, 3 and 6)

Fig. 5 shows a state where the front wheels FW are brought into contact with the operating member 64 after the removal. Since the wheel support 44 (first detection mechanism) has detected the empty state, the carriage 11 continues the state of being locked by the column 1 (fig. 3). When the operating member 64 (second detection means) is operated by the front wheels FW, the frame stopper 61 is disengaged from the lower engagement portion 4, and the engagement between the frame 12 and the pillar 1 is released. Further, the fitting between the notch of the lock pawl 511 and the slide pin 131 is released to allow the sliding movement, so that the carriage 12 can be stored in an inverted state (fig. 6).

< automatic inverted storage of vehicle body frame > (fig. 7, 9 and 8)

As shown in fig. 7, the frame 12 in the lower-stage position and horizontal state is stored in an inverted state. When the body frame 12 is stored in the inverted state, the engagement between the locking claw 412 of the lock arm 41 and the arm engagement portion 2 is maintained. The trolley 11 is locked by the column 1 (fig. 9). Since the carriage stopper 61 is separated from the lower engaging portion 4 in accordance with the rotation of the carriage 12, the carriage 11 is not engaged with the carriage 1, and the slide pin 131 can slide in the elongated hole 121 (fig. 8). The tire shield 132 is also housed along the support column 1.

< recovery from inverted state of vehicle body frame to horizontal state > (fig. 10, 9 and 8)

As shown in fig. 10, when the handle 129 is gripped to return the inverted frame 12 to the horizontal state, the frame stopper 61 is locked to the lower engaging portion 4, and the notch of the lock pawl 511 is fitted to the slide pin 131 to lock the sliding movement (fig. 9). Slide pin 131 rotates slope part 512 (rotation lock plate 51) upward, and the notch of lock pawl 511 fits into slide pin 131 to lock the sliding movement (fig. 8). The tire protector 132 is also restored to the standing state.

< end of carrying of bicycle > (fig. 11, 12 and 4)

Fig. 11 shows a state where the bicycle BCL is loaded into the horizontal frame 12 in the lower position. When the front wheel FW is placed on the wheel stay 44, the engagement between the locking claw 412 of the lock arm 41 and the arm engagement portion 2 is released, and the carriage 11 can be raised and lowered with respect to the pillar 1 (fig. 12). The frame stopper 61 is caught by the lower engaging portion 4, and the frame 12 is locked to the pillar 1. Further, the notch of the lock pawl 511 is fitted to the slide pin 131 to lock the sliding movement, and therefore, the inverted storage of the vehicle body frame 12 is prevented (fig. 4).

< storage of upper position of bicycle > (fig. 13, 14, 15)

Fig. 13 shows a state in which the frame 12 loaded with the bicycle BCL is stored at the upper position. When the front wheel FW is placed on the wheel stay 44, the engagement between the locking claw 412 of the lock arm 41 and the arm engagement portion 2 is released, and the carriage 11 can be raised and lowered with respect to the pillar 1 (fig. 14). The frame stopper 61 is caught by the upper engaging portion 3, and the frame 12 is locked and locked to the pillar 1. Further, the notch of the lock pawl 511 is fitted to the slide pin 131 to lock the sliding movement, and therefore, the inverted storage of the vehicle body frame 12 is prevented (fig. 15).

< before carrying out the lower position of bicycle > (FIGS. 16, 12 and 4)

Fig. 16 shows a state immediately before the bicycle BCL is carried out from the frame 12 in the lower-stage position and the horizontal state. When the front wheel FW is placed on the wheel stay 44, the engagement between the locking claw 412 of the lock arm 41 and the arm engagement portion 2 is released, and the carriage 11 can be raised and lowered with respect to the pillar 1 (fig. 12). The frame stopper 61 is caught by the lower engaging portion 4, and the frame 12 is locked to the pillar 1. Further, the notch of the lock pawl 511 is fitted to the slide pin 131 to lock the sliding movement, and therefore, the inverted storage of the vehicle body frame 12 is prevented (fig. 4).

The present invention can be applied to a bicycle parking device of upper and lower two-story type, but a known structure can be adopted for a bicycle parking portion of a lower story, and thus, a description thereof will be omitted.
