Technical field

The invention relates to a bicycle parking device.

Background technique

In a bicycle parking device with a vertical vertical lift type frame, the bicycle is carried into the frame at the lower position of the pillar, and the frame in the actual loading state is stored and managed in the upper position. As the storage method of the frame in the unloaded state when the bicycle is carried out, there are known types that slide and store in a horizontal state (i.e., horizontal storage) in the upper position, and the type that rotates around the base end to jump and store (i.e., upside down). Storage) type. Patent Document 1 shows the latter jump storage type. Compared with the former sliding storage type, it is possible to reduce the amount of protrusion of the frame during storage and realize space saving.

However, in Patent Document 1, the height position of the stand (frame) is different when the bicycle is carried out and when the bicycle is carried in. That is, by depressing the stand to the bicycle parking posture position lower than the parking standby posture position, and only performing the rotation lock release operation of the stand (that is, by moving the bicycle parking posture from the upper bicycle parking posture to the lower bicycle parking posture) When the bicycle is carried out after the bicycle is taken out after the operation of the position by switching the switching mechanism to the non-engagement position to release the rotation lock of the stand, the stand that is empty (that is, the unloaded state) can be automatically stored in the jumping posture position. On the other hand, after passing the parking posture position from the jumping posture position, the rotation lock action operation of the empty stand is performed only at the parking standby posture position (that is, by returning from the bicycle parking posture position below to the bicycle parking position above) The operation of the posture position can switch the switching mechanism to the engaged position to lock the rotation of the gantry into the bicycle. In this way, when the bicycle is carried out in the lower bicycle parking position, and the bicycle is carried in in the upper parking standby position, the operation is complicated and the work burden is compared with the case in which the bicycle is carried in and out at a certain height position. If it becomes larger, it is easy to cause misoperation. In particular, in the case of automatic storage of the jumping posture position to the gantry using the unloading of the bicycle as a trigger, and the lifting and movement of the gantry as an opportunity of the loading of the bicycle, the safety of the work is also possible. cause problems.

Summary of the invention

The problem to be solved by the invention

The subject of the present invention is to provide an operation for carrying out the bicycle for automatically storing the frame in an inverted state at the same height position, and for carrying in the bicycle for storage and management with the frame, making the operation simple And the bicycle parking device is safe and not easy to cause misoperation.

Means to solve the problem and the effect of the invention

In order to solve the above-mentioned problems, the bicycle parking device of the present invention includes:

A base body (such as a trolley), which is arranged in a cylindrical shape along a pillar in the vertical direction, and is configured to be able to rise and fall between the lower position and the upper position of the pillar through the application of traction force;

The frame has its own base end supported to be rotatable about the axis of rotation in the width direction relative to the lower part of the base body, and extends in the longitudinal direction (e.g., groove shape) in a cantilever shape, and is formed at the terminal end for transporting and unloading the bicycle. The entrance and exit, and in an unloaded state without a bicycle, the base end portion is provided with a moment around the axis of rotation, so as to be able to move from a horizontal state to an inverted position along the pillar with respect to the base at the lower level The state is rotated, and can be raised and lowered together with the base body between the lower position and the upper position in the actual load state with the bicycle mounted;

Side guards (e.g., supports), which are arranged at the lower level in order to prevent or suppress lateral swing vibration (ie, lateral skew), that is, yaw motion, of the bicycle that is carried in and out of the horizontal frame at the lower level. The frame is on both sides in the width direction, and one end of itself is supported so as to be able to swing relative to the upper part of the base body about the swing axis in the width direction. On the other hand, the other end is formed integrally with respect to the longitudinal direction. The guide part (specifically a long hole or a guide rail) of the middle part of the frame (close to the end part) is slidably engaged with a supported slider (specifically a sliding pin or a sliding block), thereby The side guard is erected between the base body and the frame;

A lower stop mechanism that performs a locking action such that when the base is at the lower position, the base cannot be lifted or lowered based on the traction force with respect to the pillar in the no-load state, so as to Unlocking in a manner that enables the base body to be lifted and lowered in the actual load state;

A rotation stop mechanism that prohibits sliding movement of the slider relative to the guide portion when the base is at the lower position and the frame is in the horizontal state, so that it cannot be moved relative to the base. Perform a locking action by performing the upward rotation of the frame and the side guards based on the torque, and allow sliding movement, thereby unlocking the frame in a manner capable of upward rotation; and

A movement stopper mechanism that switches between a lock operation mode in which the frame is locked to the pillar and cannot be moved at the lower position or the upper position and a lock release mode in which the frame can be moved after being unlocked,

When the base is in the lower position and the horizontal frame becomes the idling state as the bicycle is carried out, the lower stop mechanism performs a locking action to make the base relative to the The pillar cannot be raised and lowered, and the rotation stop mechanism allows the sliding movement of the slider relative to the guide portion, and the movement stop mechanism can release the frame relative to the pillar. The way of movement is such that they are interlocked with each other (for example, at the same time) to unlock, so that the frame and the side guards are rotated upward relative to the base body based on the moment, and are stored in an inverted state along the pillars .

In this way, the frame in the unloaded state when the bicycle is unloaded from the frame at the lower position is automatically stored in the upside-down state, and the frame in the actual loaded state when the bicycle is carried into the frame at the lower position is stored and managed in the upper position. Therefore, in the inverted storage type bicycle parking device, the unloading and loading operations of the bicycle are performed at the lower level, so the work load is reduced, and it is not easy to cause erroneous operations.

Moreover, along with the unloading operation of the bicycle at the lower level, the lifting and locking operation of the base body relative to the pillar is performed by the lower level stop mechanism, and the lock release operation of the slider relative to the guide part based on the rotation stop mechanism and the movement stop The unlocking operation of the frame of the mechanism with respect to the pillar is performed in conjunction with each other. That is, with the opportunity of unloading the bicycle from the frame at the lower level, the base can be fixed to the pillar, and the relative movement of the frame (the guide portion) and the side guard (the slider) and the frame relative to each other can be cancelled. Because of the locking of the pillars, it is possible to easily and safely perform the automatic storage operation of the frame in the inverted state, and it is not easy to cause misoperation.

In addition, when the frame is restored from the inverted state to the horizontal state, the locking action of the slider relative to the guide portion based on the rotation stop mechanism and the locking action of the frame relative to the pillar based on the movement stop mechanism can be linked to each other.地Execute. Therefore, even if the bicycle frame is brought into the lower position as an opportunity, the lifting lock of the base body relative to the pillar is unlocked by the lower stop mechanism, and the frame is locked to the pillar by the locking action of the movement stop mechanism. Therefore, it is possible to avoid the risk of accidental ascent of the frame in the actual load state. In this way, by providing the rotation stop mechanism and the movement stop mechanism to perform lock release or lock operations in conjunction with each other, it is possible to improve the safety in the unloading and loading operations of the bicycle in the frame at the lower level.

However, the application (mechanism) of the traction force to the base body functions (acts) to always lift the base body upward by the traction force corresponding to the total load of the base body, the frame, the side guards, and the frame-mounted bicycle. In addition, the application of the moment (mechanism) to the base end of the frame functions (acts) in such a way that the moment corresponding to the total load of the frame and the side guard makes the frame always rotate into an inverted state and store it.

The above-mentioned "side guard" is a so-called brace that is erected in an oblique cross shape on both sides in the width direction of the frame in order to prevent the mounted bicycle from falling down, and is also collectively referred to as a brace.

In addition, at the lower level, the base, the frame, and the side guards are viewed from the width direction to form a rigid triangle shape, and in an unloaded state, the frame and the side guards are configured to rotate and slide through the slider for crank motion. In the case of the crank mechanism, the frame and side guards that are unloaded when the bicycle is carried out will not bend or slack until they are stored in the upside down state, and can be used as a rotary drive unit that constitutes the rotary slide crank mechanism. The rod and the rotating driven link maintain the rigid structure. Therefore, it can be a bicycle parking device that has a strong frame storage structure that is excellent in strength and durability, and can safely and reliably store and manage various bicycles ranging from lightweight to heavyweight.

The above-mentioned "triangular shape of a rigid structure" means that the base, frame, and side guards, which are the constituent elements of the rotary slider crank mechanism, are formed into a rigid triangular shape with rigidity on each side, and are placed on the frame and side When the baffle is stored in an inverted state, no bends or slack are generated". In addition, in the rotary slide crank mechanism, it is possible to constitute a "guide portion" with a long hole, a "slider" with a slide pin, or a "guide portion" with a guide rail and a "slider" with a slide block. In addition, in the above-mentioned "rotating slider crank mechanism", the frame as the rotating drive link operates only within a range of a rotation angle of approximately 90° (1/4 rotation) from a horizontal state to an inverted state along the pillar. , So it can also be called "1/4 rotating slider crank mechanism".

The rotation stop mechanism and the movement stop mechanism are unlocked only when the above-mentioned base body is in the lower position, the frame is in a horizontal state and the lower stop mechanism performs the locking action.

In this way, in order to store the frame and the side guards in an inverted state, the locking action of the lower stop mechanism, that is, the fixing of the base to the pillar becomes a necessary condition. Therefore, safety is ensured and misoperation is unlikely to occur.

Specifically, when the bicycle is unloaded from the frame in the actual load state described above, after the lower stopper mechanism performs the locking operation, the rotation stopper mechanism and the movement stopper mechanism are unlocked.

In this way, by giving priority to the locking action of the lower stopper mechanism, the base body relative to the guide is unlocked (rotation stopper mechanism) and the frame relative to the pillar is unlocked (movement stopper mechanism). The lifting and locking operation of the pillar. As a result, based on the base fixed to the pillar, the frame and the side guards rotate upward, and are stored in an inverted state on a stable rail.

More specifically, the frame is provided with a first detection unit and a second detection unit. The first detection unit detects the bicycle in the intermediate state in order to lock the lower stopper mechanism. The second detection unit In order to unlock the rotation stop mechanism and the movement stop mechanism at the same time, the bicycle in the unloaded state is detected.

By providing such a first detection unit and a second detection unit, the operation timing of the lower-level stopper mechanism is prioritized, and it becomes easy to synchronize the operation timings of the rotation stopper mechanism and the movement stopper mechanism.

As an example, when the subsequent unloaded wheels (for example, the front wheels) retreat from the wheel support (the first detection unit), the unloading intermediate state (i.e., the unloaded movement state) is detected, the lower stopper mechanism performs the locking action, and then, in the subsequent When the unloading wheel (for example, the front wheel) is unloaded (passed) from the moving member (second detection unit) of the entrance and exit, the unloading end state (that is, the completely unloaded state) is detected to release the lock of the rotation stop mechanism and the movement stop mechanism.

When the aforementioned frame and side guards are stored in an inverted state, the lower stopper mechanism maintains the locking operation, and the rotation stopper mechanism and the movement stopper mechanism maintain the unlocked lock.

Since the lower stop mechanism, rotation stop mechanism, and movement stop mechanism maintain the state at the start of storage until the frame and side protectors are stored in the upside-down state, it prevents malfunctions before the storage in the upside-down state is completed and restores the frame It can prevent malfunction even when it reaches the horizontal state (carried into the standby state).

detailed description

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

The inverted storage type bicycle parking device 100 shown in FIG. 1 is equipped with a rotation as a basic structure for realizing the function of an inverted storage, that is, an unloaded state of the bicycle BCL that is not mounted in an inverted state. The slider crank mechanism 10, the trolley lifting mechanism 20 (traction force imparting mechanism) as a unit for driving each part, and the frame rotation mechanism 30 (torque imparting mechanism) as a unit for restricting the movement of each part The trolley lock mechanism 40 (lower-level stop mechanism), the slider lock mechanism 50 (rotation stop mechanism), and the frame lock mechanism 60 (movement stop mechanism).

As shown in Figures 1 and 2, the rotary slider crank mechanism 10 has a trolley 11 (base body) that functions as a fixed link, a frame 12 that functions as a rotary drive link, and a rotating driven link The functional support 13 (side guard) is formed into a triangle of rigid structure when viewed from the front (that is, viewed from the width direction of the frame 12).

The trolley 11 has a certain height along the pillar 1 which is erected in a cylindrical form in the vertical direction, and is provided with traction by the bogie elevating mechanism 20, and is arranged so that it can be raised and lowered by the roller 111 between the lower and upper positions of the pillar 1 ( See details later). In addition, the trolley 11 is locked to the pillar 1 at the lower position by the trolley locking mechanism 40 (details will be described later), 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 so as to be rotatable with respect to the lower part of the trolley 11 about the width direction rotating shaft 120 (rotation axis), and extends in a groove shape in the longitudinal direction in a cantilever shape. The terminal (rear end) is formed with an entrance 123 for carrying out and carrying in the bicycle BCL. The frame rotation mechanism 30 imparts a moment centered on the rotating shaft 120 to the front end in an idling state, and is arranged so that it can rotate from a horizontal state to an inverted state along the pillar 1 with respect to the trolley 11 located at the lower level. (Details will be described later), in the rotary slider crank mechanism 10, it functions as a rotary drive link. Furthermore, the frame 12 can be locked to the pillar 1 by the frame locking mechanism 60 (details will be described later).

The support 13 is arranged in a pair on both sides in the width direction of the frame 12, and the left support 13L and the right support 13R (refer to FIGS. 3 and 4) are supported at one end (upper end in FIGS. 1 to 4). In order to be able to swing with respect to the upper part of the trolley 11 with the swing shaft 130 (swing axis) in the width direction as the center. On the other hand, the other end portions (lower end portions in FIGS. 1 to 4) of the left and

right supports

13L and 13R are formed to be fixed to the middle portion along the frame 12 and near the rear end portion (terminal portion). The long hole 121 (guide portion) integrally formed in the longitudinal direction of the shaped member 122 is engaged and supported by the sliding pin 131 (slider) that is slidably movable in the unloaded state of the lower position. The rotary slider crank mechanism In 10, it functions as a rotary driven link. In addition, the support 13 is a pair of left and right diagonal struts erected in an oblique cross between the trolley 11 and the frame 12 to prevent or suppress the lateral swing of the bicycle BCL that is carried out and carried into the horizontal frame 12 at the lower level. Vibration (ie, left-right skew) means yaw movement, or prevents the BCL of the bicycle from falling. Furthermore, the sliding movement of the sliding pin 131 with respect to the elongated hole 121 can be locked by the slider locking mechanism 50 (details are described later).

That is, at the lower level of the pillar 1, the trolley 11, the frame 12, and the support 13 have a rigid body structure that is approximately right-angled triangles in which the trolley 11 and the frame 12 cross at a substantially right angle when viewed from the front, and the support 13 forms a hypotenuse. Strictly speaking, the straight line connecting the rotation shaft center C120 and the swing shaft center C130 and the straight line connecting the rotation shaft center C120 and the slider center C131 form an approximately right triangle that intersects at a substantially right angle. In this way, the rotary slider crank mechanism 10 in which the frame 12 and the support 13 are cranked via the slide pin 131 is constituted. Therefore, in the idling state, the sliding pin 131 slides and moves in the longitudinal direction in the long hole 121, and the frame 12 and the support 13 rotate upward relative to the trolley 11 and are stored in an upside-down state along the pillar 1. In this inverted state, the frame 12 overlaps the trolley 11 and the support 13 and is stored 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. In addition, the trolley 11, the frame 12, and the support 13 are formed into a firm triangle with rigidity on each side, so that when the frame 12 and the support 13 are stored in an inverted state, no bends or slack are generated.

In the rotary slider crank mechanism 10 of the present embodiment, the frame 12 as the rotary drive link is only in the range of a rotation angle (1/4 rotation) of approximately 90° from the horizontal state to the inverted state along the pillar 1. Internal action (refer to Figure 7), so it can also be called "1/4 rotary slider crank mechanism."

In addition, the example of a structure composed of a "rotating slider crank mechanism" is usually imitated (for example, a star-shaped rotary engine). In addition, although in contrast to the name of the mechanism, the sliding pin 131 of the support 13 is usually used as a rotary drive link (Active part), but in this embodiment, considering the strength of the constituent parts, (the long hole 121 of the frame 12) is used as a rotation drive link.

In the vicinity of the high position side end of the support 13 constituting the hypotenuse (that is, close to the pillar 1) and when viewed from the front, between the wheel support 44 (described later) and the swing shaft 130, it stands upright from the support 13 and A tire guard 132 for holding the front wheel FW (wheel-in advance) of the bicycle BCL mounted on the frame is undulated freely. The tire guard 132 is formed in an inverted U shape that protrudes upward from one support (for example, the left support 13L) and bypasses the tire of the front wheel FW to reach the other support (for example, the right support 13R). When the frame 12 in the horizontal state is carried into the bicycle BCL, it straddles both sides of the front wheel FW from above and is held inside (refer to FIG. 11). In this way, when the bicycle BCL is carried into the frame 12, the tire guard 132 functions as a tire holder that holds the tire of the front wheel FW inside.

The upright biasing spring 133 is spanned between the support 13 and the tire guard 132 and maintains the tire guard 132 in a posture that always stands upright with respect to the support 13. When the frame 12 and the support 13 in the unloaded state rotate upward to reach the inverted state, the upper end of the tire guard 132 contacts the pillar 1, and overcomes the force of the upright biasing spring 133 to follow the pillar 1. The posture is gradually changed in the manner of, and when viewed from the front, it overlaps with the frame 12 and is stored (refer to FIG. 7). In this way, when the frame 12 in the unloaded state is in an upside down state and is stored, the tire guard 132 functions as a storage guide that comes into contact with the pillar 1 and is gradually folded and stored.

Returning to FIG. 1, the base end of the lifting gas spring 21, which constitutes the main part of the bogie lifting mechanism 20, is attached to the upper end of the pillar 1, and a movable pulley is attached to the terminal (lower end) of the downwardly protruding piston rod 21R twenty two. In addition, a fixed pulley 23 is also attached to the upper end of the pillar 1. One end of the connecting wire 24 is fixed to a predetermined position in the pillar 1, and after being wound in the order of the movable pulley 22 and the fixed pulley 23, the other end is fixed to the upper end surface of the trolley 11. When the piston rod 21R is retracted (contracted), the frame 12 is located at the lower stage together with the trolley 11, and the bicycle BCL is loaded into the actual load state (see FIG. 11). Due to the protrusion (extension) of the piston rod 21R, the frame 12 rises to the upper position together with the trolley 11 to store the bicycle BCL (see FIG. 13).

As shown in Figures 1 and 2, the frame rotating mechanism 30 is mainly composed of a rotating gas spring 31, the base end of which is attached to the upper end of the trolley 11, and on the other hand, the front end of the piston rod 31R is attached to the frame 12 of the front end. The pushing force of the piston rod 31R generates a moment that separates the distance between the terminal mounting position of the piston rod 31R and the rotation axis C120 in the horizontal direction as the length of the arm. When the piston rod 31R is retracted (reduced), the frame 12 maintains a horizontal state (refer to FIG. 5). On the other hand, when the piston rod 31R protrudes (stretches), the frame 12 and the support 13 rotate upward with respect to the trolley 11 and are accommodated in an inverted state along the pillar 1 (see FIG. 7).

However, the lifting gas spring 21 of the trolley lifting mechanism 20 always pulls the trolley 11 upward by the traction force corresponding to the total load of the trolley 11, the frame 12, the support 13, and the frame-mounted bicycle BCL Play a role. In addition, the rotation gas spring 31 of the frame rotation mechanism 30 functions to always store the front end of the frame 12 in an inverted state by a moment corresponding to the total load of the frame 12 and the support 13.

The trolley lock mechanism 40 shown in FIGS. 1 and 2 functions when the trolley 11 is in the lower position: in an unloaded state, the trolley cannot perform the traction force of the lifting gas spring 21 with respect to the pillar 1 The locking operation of 11 is performed in the manner of lifting (refer to FIG. 3), and the lock is released in a manner capable of lifting (refer to FIG. 12) in the actual load state.

Specifically, as shown in FIG. 3, the lock arm 41 is swingably attached to a support shaft 42 arranged in the width direction of the trolley 11, and the lower end of the lock arm 41 is bent forward in an L-shape to form a lock. Claw 412. The locking pawl 412 can be engaged with the arm engaging portion 2 formed at the lower position of the pillar 1, and an arm urging spring 43 is arranged between the trolley 11 and the upper end of the locking arm 41, and the locking pawl 412 always faces and The direction in which the arm engaging portion 2 engages (the front side) is urged. In addition, a protrusion 411 is formed protruding downward at the rear of the locking claw 412.

In addition, at the front end portion of the frame 12, a wheel support 44 for blocking the front wheel FW (advanced carry-in wheel) of the carried-in bicycle BCL is arranged so as to be capable of swinging back and forth. The wheel support 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 support 44 and the frame 12. The front end of the extension rod 45 is bent into an L-shape in the width direction to form a hooking portion 451. The hooking portion 451 surrounds the protrusion 411 formed at the lower end of the lock arm 41 and is located forward.

As shown in FIG. 3, when the frame 12 is in an unloaded state, that is, when the front wheel FW is not mounted on the wheel support 44, due to the force of the lever biasing spring 46, the wheel support 44 tilts backward and the extension rod 45 moves forward. The hook portion 451 is located forward of the protrusion 411. The lower end of the lock arm 41 is urged to the front side by the arm urging spring 43, and the locking pawl 412 is engaged with the arm engaging portion 2 to be locked. That is, the trolley lock mechanism 40 performs a lock operation so that the trolley 11 cannot be raised and lowered with respect to the pillar 1.

On the other hand, as shown in FIG. 12, when the frame 12 is in a real-loaded state, that is, when the front wheel FW is placed on the wheel support 44, the wheel support 44 is inclined forward against the force of the lever biasing spring 46 to extend it. Since the rod 45 retreats, the hooking portion 451 engages with the protrusion 411 and is pulled backward. The locking pawl 412 of the lock arm 41 overcomes the total force of the arm urging spring 43 and the lever urging spring 46 and rotates to the rear side, thereby releasing the engagement with the arm engagement portion 2. That is, the trolley lock mechanism 40 releases the lock so that the trolley 11 can be raised and lowered with respect to the pillar 1.

In addition, as shown in FIG. 9, when the frame 12 is stored in an inverted state, that is, when the frame 12 rotates around the swing shaft 130, the hook portion 451 gradually moves away from the protrusion 411. The lower end of the lock arm 41 is urged to the front side by the arm urging spring 43, and the locking pawl 412 is engaged with the arm engaging portion 2 to be locked. That is, the trolley lock mechanism 40 performs a lock operation so that the trolley 11 cannot be raised and lowered with respect to the pillar 1.

Returning to Figures 1 and 2, the slider locking mechanism 50 performs a locking action by prohibiting the sliding movement of the sliding pin 131 relative to the elongated hole 121 when the trolley 11 is in the lower position and the frame 12 is horizontal, so that the relative The bogie 11 cannot perform upward rotation of the frame 12 and the support 13 based on the torque of the rotation gas spring 31 (refer to 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 frame 12 and the support 13 can be rotated upward (refer to FIG. 6).

In addition, the frame locking mechanism 60 is switched between a locking operation mode (refer to FIG. 4 or FIG. 15) in which the frame 12 is locked to the pillar 1 in the lower position or in the upper position, and a movable mode in which the frame 12 is unlocked. Lock release method (refer to Figure 6). The switching between the lock operation mode and the lock release mode in the frame lock mechanism 60 is performed based on the operation of the operation member 64 which is arranged at the entrance 123 of the frame 12 and doubles as an unloaded detection unit and an artificial operation unit. The locking operation and unlocking of the locking mechanism 50 are simultaneously performed in conjunction with each other (refer to FIGS. 4 and 6).

Specifically, as shown in FIG. 4, a lower-layer engaging portion 4 is formed at the lower position of the pillar 1 so that the protruding amount toward the rear side becomes larger as it goes downward, and a stopper is provided below the frame 12. The force spring 62 always urges the frame stopper 61 toward the pillar side (front side). The frame stopper 61 is connected via a connecting rod 63 extending in the longitudinal direction of the frame 12 to an action member 64 provided at the entrance 123 in the form of a detection mechanism in an unloaded state and an artificial operating mechanism.

The support plate 124 is fixed to the frame 12, and one end of the rotation lock plate 51 is provided so as to be rotatable about the rotation shaft 52 arranged in the width direction of the support plate 124. A locking pawl 511 including a cutout opening downward is formed at the other end of the rotation locking plate 51, and the cutout of the locking pawl 511 can be fitted into the sliding pin 131 from above. Between the rotation shaft 52 and the locking pawl 511, an oblique long hole 513 is formed in a direction intersecting the long axis arrangement direction (ie, the horizontal direction) of the long hole 121, and an operation pin 53 is formed protruding from the connecting rod 63 in the width direction. Inserted into the oblique long hole 513. At the end portion of the rotation lock plate 51 that is closer to the end than the lock claw 511, an inclined surface portion 512 that is inclined in a direction different from the inclined elongated hole 513 is formed.

As shown in FIG. 4, when the trolley 11 is in the lower position and the frame 12 is in a horizontal state, the actuating member 64 does not operate and the connecting rod 63 is not pulled, the frame stopper 61 is stopped by the urging spring 62 applies force to the front side and is locked in a state where the upper and lower layer engaging portions 4 are mounted. That is, the frame lock mechanism 60 performs a lock operation so that the frame 12 is locked to the pillar 1 and cannot be moved. In addition, the operating pin 53 is located at the front end of the oblique long hole 513 and does not rotate the rotation lock plate 51. Therefore, the cutout of the lock pawl 511 fits the sliding pin 131 to lock the sliding movement so that the frame 12 and the support 13 cannot be moved. Rotate upwards for locking action. That is, the slider lock mechanism 50 prohibits the sliding movement of the slide pin 131, and performs a lock operation so that it cannot be stored upside down.

On the other hand, as shown in FIG. 6, when the trolley 11 is in the lower position and the frame 12 is in a horizontal state, when the actuating member 64 moves to pull the connecting rod 63, the frame stopper 61 overcomes the stopper force The spring 62 moves to the rear side, and the engagement with the lower-layer engaging portion 4 is released. That is, the frame lock mechanism 60 releases the lock so that the frame 12 can be moved by releasing the locking of the frame 12 with respect to the pillar 1. In addition, the operating pin 53 is moved to the rear side of the oblique long hole 513 to rotate the rotation lock plate 51 upward, and the engagement between the notch of the lock pawl 511 and the sliding pin 131 is released to allow sliding movement, so that the frame 12 and support can be carried out. The upward rotation of the piece 13 releases the lock. That is, the slider lock mechanism 50 allows the sliding movement of the slide pin 131, and releases the lock so that it can be stored upside down.

In addition, when the frame 12 is stored in the inverted state, that is, when the frame 12 is rotated about the swing shaft 130, the frame stopper 61 gradually moves away from the lower-layer engaging portion 4. That is, the frame lock mechanism 60 releases the lock so that the frame 12 can be moved by releasing the locking of the frame 12 with respect to the pillar 1. In addition, as shown in FIG. 8, the sliding pin 131 can slide and move in the long hole 121 regardless of the rotation lock plate 51. That is, the slider lock mechanism 50 allows the sliding movement of the slide pin 131, and releases the lock so that it can be stored upside down.

Also, when the frame 12 is restored from the inverted state to the horizontal state, by moving in the direction opposite to the storage toward the inverted state, the frame stopper 61 is also locked to the lower engaging portion 4, and the cutout of the locking pawl 511 and The sliding pin 131 is fitted to lock the sliding movement. At this time, when the sliding pin 131 slides in the direction opposite to the arrow in FIG. 8 into the long hole 121, the sliding pin 131 sneaks into the inclined surface portion 512 of the lock pawl 511, and the rotation lock plate 51 is rotated upwards centered on the rotation shaft 52 , The notch of the locking pawl 511 is fitted with the sliding pin 131 to lock the sliding movement.

In this way, when the trolley 11 is located at the lower level and the frame 12, which is in a horizontal state with the removal of the bicycle BCL, becomes an unloaded state (see FIG. 5), the trolley lock mechanism 40 prevents the trolley 11 from being relative to the pillar 1. The locking action is carried out in a lifting manner (refer to FIG. 3), and the slider locking mechanism 50 allows sliding movement of the sliding pin 131 with respect to the elongated hole 121, and the frame locking mechanism 60 can release the locking of the frame 12 with respect to the pillar 1 While moving, by simultaneously unlocking in conjunction with each other (refer to FIG. 6), the frame 12 and the support 13 are rotated upward relative to the trolley 11 to be in an inverted state along the pillar 1 based on the torque of the rotating gas spring 31 It is stored (refer to Figure 7).

Moreover, when the frame 12 is restored from the inverted state to the horizontal state by the manual operation of the action member 64, the locking action of the slide pin 131 with respect to the long hole 121 based on the slide lock mechanism 50 is similar to that of the vehicle frame based on the frame lock mechanism 60. The locking and locking actions of the frame 12 with respect to the pillar 1 are executed in conjunction with each other (refer to FIG. 10).

In this way, the frame 12 and the support 13 in the unloaded state after the bicycle BCL is carried out will not bend or slack until it is stored in the inverted state, and serve as the rotary drive link constituting the rotary slider crank mechanism 10 And the rotating driven link can maintain the rigid body structure. Therefore, it is possible to provide a bicycle parking device 100 that has a strong frame storage structure that is excellent in strength and durability, and can safely and reliably store and manage various bicycles ranging from lightweight to heavyweight.

Furthermore, the bicycle BCL that is unloaded from the frame 12 at the lower position is automatically stored in the inverted state, and the bicycle BCL is carried into the frame 12 at the lower position, and the real-loaded bicycle frame 12 is in the upper position. It is kept and managed. Therefore, in the bicycle parking device 100 of the inverted storage type, the unloading and loading operations of the bicycle BCL are performed at the lower level. Therefore, the work load is reduced, and it is not easy to cause erroneous operations.

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

＜Lower floor position, halfway of unloading the bicycle from the horizontal frame＞ (Figure 1, Figure 3 and Figure 4)

As shown in Fig. 1, the front wheel FW is located behind the wheel support portion 44 and forward of the motion member 64, and the bicycle BCL is in the middle of being carried out. The wheel support 44 (first detection mechanism) detects the unloaded state when the unloading is completed, the locking pawl 412 is engaged with the arm engaging portion 2, and the trolley 11 is locked by the pillar 1 (FIG. 3 ). The front wheel FW is not in contact with the moving member 64 (second detection mechanism), and is not detected as being unloaded (unloaded state), so the frame stopper 61 is caught by the lower engaging portion 4, and the frame 12 is locked and locked于pillar 1. In addition, the notch of the lock pawl 511 is fitted with the slide pin 131 to lock the sliding movement, and therefore the inverted storage of the frame 12 is prevented (FIG. 4 ).

<The removal of the bicycle from the frame is complete> (Figure 5, Figure 3, and Figure 6)

FIG. 5 shows a state where the front wheel FW has finished unloading and is in contact with the operating member 64. Since the wheel support 44 (first detection mechanism) has detected the idling state, the trolley 11 continues to be locked by the pillar 1 (FIG. 3 ). When the front wheel FW activates the action member 64 (second detection mechanism), the frame stopper 61 is disengaged from the lower-layer engaging portion 4, and the engagement of the frame 12 and the pillar 1 is released. In addition, the engagement between the cutout of the lock pawl 511 and the slide pin 131 is released, and the sliding movement is allowed, so that the frame 12 can be stored upside down (FIG. 6 ).

<Automatic inverted storage of the frame> (Figure 7, Figure 9, and Figure 8)

As shown in FIG. 7, the frame 12 at the lower level and in a horizontal state is stored in an inverted state. When the 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 pillar 1 (Figure 9). The frame stopper 61 is separated from the lower engaging portion 4 as the frame 12 rotates, so the trolley 11 does not engage with the frame 1, and the sliding pin 131 can slide in the long hole 121 (FIG. 8 ). The tire guard 132 is also stored along the pillar 1.

<Recovering from the inverted state of the frame to the horizontal state> (Figure 10, Figure 9 and Figure 8)

As shown in FIG. 10, when the frame 12 in the inverted state is restored to the horizontal state by grasping the handle 129, the frame stopper 61 is locked to the lower engaging portion 4, and the cutout of the locking pawl 511 is fitted to the sliding pin 131 And lock the sliding movement (Figure 9). The sliding pin 131 rotates the inclined surface portion 512 (rotation lock plate 51) upward, and the notch of the locking pawl 511 is fitted with the sliding pin 131 to lock the sliding movement (Fig. 8). The tire guard 132 also returns to the upright state.

<End of loading of bicycles> (Figure 11, Figure 12, and Figure 4)

FIG. 11 shows a state where the frame 12 in the lower position and the horizontal state is finished being loaded into the bicycle BCL. By placing the front wheel FW on the wheel support 44, the engagement between the locking pawl 412 of the lock arm 41 and the arm engagement portion 2 is released, and the trolley 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 and locked to the pillar 1. In addition, the notch of the lock pawl 511 is fitted with the slide pin 131 to lock the sliding movement, and therefore the inverted storage of the frame 12 is prevented (FIG. 4 ).

<Storage of the upper level of the bicycle> (Figure 13, Figure 14, Figure 15)

FIG. 13 shows a state in which the frame 12 loaded with the bicycle BCL is stored in the upper position. By placing the front wheel FW on the wheel support 44, the engagement between the locking pawl 412 of the lock arm 41 and the arm engagement portion 2 is released, and the trolley 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. In addition, the notch of the lock pawl 511 is fitted with the slide pin 131 to lock the sliding movement, and therefore the upside down storage of the frame 12 is prevented (FIG. 15 ).

<Before moving out of the lower level of the bicycle> (Figure 16, Figure 12, and Figure 4)

FIG. 16 shows a state immediately before the bicycle BCL is carried out from the frame 12 in the lower level position and in a horizontal state. By placing the front wheel FW on the wheel support 44, the engagement between the locking pawl 412 of the lock arm 41 and the arm engagement portion 2 is released, and the trolley 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 and locked to the pillar 1. In addition, the notch of the lock pawl 511 is fitted with the slide pin 131 to lock the sliding movement, and therefore the inverted storage of the frame 12 is prevented (FIG. 4 ).
