Description

The present invention relates to a bicycle parking device in which an elongated storage rack for mounting a bicycle moves laterally on a fixed rail arranged horizontally.

The laterally movable bicycle parking device has a simple structure and operation, has good bicycle storage efficiency, and is relatively inexpensive to install and maintain. Therefore, it is a permanent outdoor bicycle parking lot or condominium on the sidewalk or in a park.・ It is widely used regardless of whether it is an indoor bicycle parking lot opened in an apartment or an underground bicycle parking lot attached to a building or underground station. It is also used in the lower bicycle parking device in the upper and lower two-stage bicycle parking machine.

In such a laterally movable bicycle parking device, the storage rack moves horizontally along a pair of parallel fixed rails or by one fixed rail and one or more casters (ie, auxiliary wheels). Even if the user is a child or an elderly person, the bicycle parking work can be done easily. On the other hand, when the bicycle is brought in, the storage rack tends to shift laterally (that is, escape laterally), which may cause a mistake in carrying the bicycle, damage to the storage rack and the bicycle, and injuries to the user. There is.

In order to prevent the storage rack from laterally shifting when the bicycle is carried in, the applicant of the present application has described in Patent Document 1 a technique for stopping the lateral displacement of the storage rack by putting the auxiliary wheel in a floating state by grounding the braking mechanism (elevating braking body). Disclosed. Since the elevating and braking body of Patent Document 1 does not directly exert a braking force on the fixed rail and the auxiliary wheel, it is possible to suppress the surface deterioration of the fixed rail and the auxiliary wheel over time, and the durability is improved (that is, for a long period of time). (Securing stable lateral slide movement) can be achieved.

By the way, in order to efficiently accommodate a plurality of bicycles in the bicycle parking space, the fixed rail and the storage rack may be arranged diagonally as in Patent Document 1, for example. However, since the shape and size of each bicycle parking space are different, the positional relationship (direction and angle) of the diagonal intersection cannot be uniquely determined. In any case, when the storage racks are arranged diagonally with respect to the fixed rails, the lateral displacement of the storage racks may be caused by the lateral component of the external force acting in the longitudinal direction of the storage racks when the bicycle is carried in. It gets higher. The "external force" here means "the propulsive force for moving the bicycle forward (on the storage rack that tries to maintain the stationary state)", and can be mainly expressed by "the pushing force of the bicycle by the user". .. Then, the direction in which the lateral component force acts changes in the opposite direction (that is, leftward or rightward) depending on the positional relationship in which the fixed rail and the storage rack intersect diagonally. However, the elevating and braking body described in Patent Document 1 cannot cope with this change, and there is a possibility that it cannot be sufficiently exerted while having an excellent braking function.

Registered Utility Model No. 3199824

An object of the present invention is to provide a bicycle parking device capable of more reliably preventing lateral displacement of a storage rack when a bicycle is carried in without exerting a braking force on a fixed rail or an auxiliary wheel.

Means for Solving Problems and Effects of Invention

In order to solve the above problems, the present invention
A storage rack in which the entrance and exit of wheels for mounting a bicycle are formed at one end in the longitudinal direction, and on the reference plane along the lateral direction that diagonally intersects the longitudinal direction in a plan view on the other end side of the storage rack. A bicycle parking device having a fixed rail arranged horizontally and having the storage rack mounted so as to be slidable in the lateral direction along the fixed rail.
The storage rack has an auxiliary wheel that can roll laterally while supporting the storage rack when it is in a landing state on the bottom surface side of the storage rack, and its tip is in the vicinity of the auxiliary wheel. An elevating and braking body that can be changed to a state of touching down at a protruding position protruding below the lower edge of the auxiliary wheel and a state of standing by at a retracted position retracting above the lower edge is provided.
The elevating braking body receives the lateral component force generated by the external force acting in the longitudinal direction of the storage rack when the bicycle is carried into the storage rack, so that the lateral component of the left and right sides with respect to the center line in the longitudinal direction is received. Placed on the side where the force acts,
When the elevating braking body is displaced from the retracted position to the protruding position by an artificial operation, the auxiliary wheel is brought into a floating state, and the lateral displacement of the storage rack based on the lateral component force is stopped. It is a feature.

In addition, in order to solve the above problems, the present invention
A storage rack in which the entrance and exit of wheels for mounting a bicycle are formed at one end in the longitudinal direction, and on the reference plane along the lateral direction that diagonally intersects the longitudinal direction in a plan view on the other end side of the storage rack. A bicycle parking device having a fixed rail arranged horizontally and having the storage rack mounted so as to be slidable in the lateral direction along the fixed rail.
The storage rack has an auxiliary wheel that can roll laterally while supporting the storage rack when it is in the landing state on the bottom surface side of the storage rack, and its tip is in the vicinity of the auxiliary wheel. The elevating and braking body that can be changed to a state of touching the ground at a protruding position protruding below the lower edge of the auxiliary wheel and a state of standing by at a retracting position retracting above the lower edge, and the elevating and lowering braking body are described above. An operating member that is artificially operated only to displace the bicycle from the retracted position to the protruding position, and to return the lifting / braking body from the protruding position to the retracted position based on the loading of the bicycle into the storage rack. A return mechanism is provided,
The elevating and braking body receives the lateral component force generated by the external force acting in the longitudinal direction of the storage rack when the bicycle is carried into the storage rack, so that the lateral component of the left and right sides with respect to the center line in the longitudinal direction is received. Placed on the side where the force acts,
In an empty vehicle state in which the bicycle is not mounted on the storage rack, the elevating and braking body is displaced from the retracted position to the protruding position by an artificial operation of the operating member to bring the auxiliary wheel into a floating state, and the lateral component force is applied. While stopping the lateral displacement of the storage rack based on
By the operation of the return mechanism based on the loading of the bicycle into the storage rack, the elevating and braking body returns from the protruding position to the retracted position, returns the auxiliary wheel to the landing state, and mounts the bicycle on the storage rack. It is characterized in that the storage rack can be slid and moved in the lateral direction in an actual vehicle state.

In these inventions, the elevating and braking body is arranged on the side where the lateral component force acts with respect to the center line in the longitudinal direction of the storage rack, and is displaced to the protruding position when the bicycle is carried in to bring the auxiliary wheel into a floating state. Stop the lateral displacement of the storage rack based on the directional component force. As described above, the elevating and braking body of the present invention is arranged on the acting side of the lateral component force, is displaced to the protruding position on the acting side, and is fixed by receiving the lateral component force generated when the bicycle is carried in. Even if the braking force is not directly applied to the rails and auxiliary wheels, it is possible to reliably prevent the storage rack from laterally shifting when the bicycle is carried in. Therefore, it is possible to arbitrarily set the positional relationship (intersection direction and intersection angle) of the diagonal intersection between the fixed rail and the storage rack according to the shape and size of the bicycle parking space where the bicycle parking device is installed. Become.

In addition to the elevating and braking body, the above-mentioned storage rack can be changed to a contact state in which its lower surface contacts the reference surface based on artificial operation and a non-contact state in which its lower surface does not contact the reference surface based on the release of artificial operation. The auxiliary braking body is arranged on at least one of the left and right sides with respect to the center line in the longitudinal direction.
The sub-brake body is artificially operated when the bicycle is carried out from the storage rack or when the bicycle is carried into the storage rack, and is in a contact state, so that the auxiliary braking body causes irregular movements that occur in the storage rack when the bicycle is taken in and out. Stop or suppress.

As mentioned above, the "external force" that acts on the storage rack when the bicycle is taken in and out is the "propulsive force that moves the bicycle back and forth", and specifically, it is mainly grasped as the "force that the user pushes and pulls the bicycle". .. Furthermore, due to this "propulsive force for moving the bicycle back and forth", the elongated storage rack has rolling motion (rolling vibration) and pitching motion (pitching) around the horizontal axis perpendicular to the longitudinal direction. Irregular movements based on swaying vibrations), yawing movements (swinging vibrations around the vertical axis perpendicular to the longitudinal direction), or these combined movements are likely to occur, sometimes accompanied by elastic deformation such as bending and twisting. .. In particular, the storage rack is prone to undulating and irregular movements due to rolling motion and torsional deformation. At this time, if the lifting / braking body is in the retracted position, the braking function is not exerted, and even if the lifting / braking body is in the protruding position, the braking function is diminished, which causes harm to the storage rack, the mounted bicycle, the user, etc. there is a possibility.

Therefore, in addition to the elevating and lowering braking body, it is desirable to provide the storage rack with an auxiliary braking body that can be changed into a contact state in contact with the reference surface and a non-contact state in which the reference surface is not contacted. By preventing or suppressing these irregular movements generated in the storage rack by the auxiliary braking body, the bicycle can be taken in and out more safely. If the auxiliary braking body is in a position where it is easy for the user who senses irregular movement to operate it at a moment's notice, the auxiliary braking body may be arranged only on either the left or right side with respect to the center line in the longitudinal direction. It may be arranged on both sides in consideration of individual differences of the person.

Specifically, both the elevating brake body and the auxiliary brake body described above are located near one end in the longitudinal direction of the storage rack, and are arranged along the longitudinal direction with the auxiliary wheels sandwiched between them.

As a result, both the elevating brake body and the auxiliary brake body are located near the entrance / exit of the bicycle and the auxiliary wheels, so that the user can simultaneously observe the conditions of the bicycle, the storage rack, and the auxiliary wheels when the bicycle is taken in and out. However, both braking bodies can be operated quickly.

More specifically, the above-mentioned auxiliary braking body is arranged on the one end side in the longitudinal direction of the elevating braking body and adjacent to the entrance / exit.

By arranging the auxiliary braking body adjacent to the entrance / exit of the wheel in this way, when the user feels irregular shaking of the bicycle or the storage rack during the loading / unloading work, the loading / unloading of the bicycle is immediately interrupted. Since the auxiliary brake body can be operated, danger can be quickly avoided.

The sub-brake body described above may be in a contact state based on an artificial operation or a non-contact state based on the release of the artificial operation regardless of whether the evacuation braking body is in the retracted position or the protruding position.

As a result, when the user feels irregular shaking of the bicycle or storage rack during loading / unloading work or lateral sliding movement, the auxiliary braking body is immediately used regardless of whether the lifting / lowering braking body is in the retracted position or the protruding position. You can avoid the danger by performing the operation of. In addition, if irregular shaking or the like subsides, regardless of whether the evacuation braking body is in the retracted position or the protruding position, the operation of the auxiliary braking body is immediately released to return to the bicycle loading / unloading work or the lateral sliding movement of the storage rack. be able to.

Further, the auxiliary braking body described above is provided with an urging member that constantly applies an urging force in a direction away from the reference plane.
In the contact state, the auxiliary braking body is pressed against the reference surface against the urging force of the urging member by artificial operation, while in the non-contact state, the urging force of the urging member is received by the release of the artificial operation. And deviate from the reference plane.

As a result, when the user feels irregular shaking of the bicycle or storage rack while moving in and out or sliding sideways, the auxiliary braking body can be immediately operated to avoid danger, and irregular shaking or the like can occur. Once it is settled, the operation of the auxiliary braking body can be immediately released to return to the work of putting in and taking out the bicycle or the lateral sliding movement of the storage rack. In this way, since the braking function of the sub-brake body is exerted only while the user is operating, the bicycle parking device can be made with excellent safety and operability.

(First example)
Hereinafter, embodiments of the present invention will be described with reference to the examples shown in the drawings. FIG. 1 is an overall plan view showing an example of the bicycle parking device of the present invention, FIG. 2 is a partially enlarged plan view of FIG. 1, and FIG. 3 is a front view of FIG. The bicycle parking device 1 of the first example shown in FIGS. 1 to 3 has a long girder shape (see FIGS. 11 and 12) in the front-rear direction for mounting the front wheel FW and the rear wheel RW of the bicycle BCL, and exhibits a longitudinal direction (that is, that is). A plurality of storage racks 2 (three in the figure) in which the doorways 2a of the wheels FW and RW are formed at one end (rear end in this case) of the front-rear direction, and the lateral direction (that is, left and right) intersecting the longitudinal direction of the storage rack 2. It is provided with a fixed rail 4 arranged horizontally in the direction). Specifically, the slide frames 3 fixed to the bottom surface side of the other end (the front end in this case) of the storage rack 2 are grounded via a plurality of rollers 5 (rolling bodies) (six in total in the figure). It is configured as a lateral slide movable type that can move laterally along a fixed rail 4 installed on a reference surface such as the surface E.

The storage rack 2 (and slide frame 3) and the fixed rail 4 are arranged diagonally intersecting each other so that the number of bicycles parked can be increased by effectively utilizing the bicycle parking space, and the storage rack 2 is diagonally oriented with respect to the longitudinal direction. Slide sideways in the direction. Specifically, as shown in FIG. 2, with respect to the orthogonal line RL of the fixed rail 4, the entrance / exit 2a at the rear end is on the right side (that is, counterclockwise) in a plan view starting from the slide frame 3 at the front end. The center line CL in the longitudinal direction of the storage rack 2 is obliquely crossed in such a manner that the crossing angle α is swung. In the following description, the mode shown in the first example is referred to as a right swing type having a right swing angle α (α = 45 ° in the figure).

The storage rack 2 shown in the first example has a caster 10 (auxiliary wheel), an elevating brake 20 (elevating braking body), a foot pedal 30 (operating member), and a rotary brake 50 on the rear end side, which is one end side thereof. (Auxiliary braking body) is provided, and a return mechanism 40 is provided so as to straddle the front end side to the rear end side, which is the other end side (details of each part will be described later).

As shown in FIG. 1, when the bicycle BCL is carried in, the propulsive force F for moving the bicycle BCL forward (on the storage rack 2 for maintaining a stationary state) is, in other words, the pushing force of the bicycle BCL by the user. Therefore, it works as an external force to move the storage rack 2 in the longitudinal direction. This propulsive force F is decomposed into an orthogonal component force FR, which is a component in the direction orthogonal to the fixed rail 4, and a lateral component force FS, which is a component in the direction parallel to the fixed rail 4.
FR = F ・ cosα
FS = F ・ sinα
Of these, the orthogonal component force FR is received by the fixed rails 4 and 5, and the storage rack 2 cannot be moved, but the lateral component force FS can cause lateral displacement of the storage rack 2. Then, in the right swing type having the right swing angle α, the lateral component force FS acts so as to laterally shift the storage rack 2 to the left.

Therefore, in the first example, the elevating brake 20 (detailed structure will be described later) is the longitudinal center line of the storage rack 2 in order to stop the lateral displacement of the storage rack 2 due to the lateral component force FS facing left when the bicycle BCL is carried in. It is located on the left side of CL.

(Second example)
4 is an overall plan view showing another example of the bicycle parking device of the present invention, FIG. 5 is a partially enlarged plan view of FIG. 4, and FIG. 6 is a front view of FIG. In the bicycle parking device 1 of the second example shown in FIG. 5, the entrance / exit 2a at the rear end is on the left side (that is, clockwise) in a plan view with respect to the orthogonal line RL of the fixed rail 4 starting from the slide frame 3 at the front end. ), The center line CL in the longitudinal direction of the storage rack 2 is diagonally intersected. In the following description, the mode shown in the second example is referred to as a left swing type having a left swing angle β (β = 45 ° in the figure).

The storage rack 2 shown in the second example also has a caster 10 (auxiliary wheel), a lift brake 20 (lift brake body), a foot pedal 30 (operation member), and a rotary brake 50 on the rear end side, which is one end side thereof. (Auxiliary braking body) is provided, and a return mechanism 40 is provided from the front end side to the rear end side, which is the other end side (the structure of each part is the same as that of the first example).

As shown in FIG. 4, the propulsive force F for moving the bicycle BCL forward is decomposed into an orthogonal component force FR and a lateral component force FS as in the first example (FIG. 1).
FR = F ・ cosβ
FS = F ・ sinβ
Then, in the left swing type having the left swing angle β, the lateral component force FS acts so as to laterally shift the storage rack 2 to the right.

Therefore, in the second example, the elevating brake 20 (the detailed structure is the same as that of the first example) is used in the storage rack 2 in order to stop the lateral displacement of the storage rack 2 due to the lateral component force FS facing to the right when the bicycle BCL is carried in. It is arranged on the right side of the longitudinal center line CL of.

In this way, the elevating brake 20 receives the lateral component force FS generated by the propulsive force F (external force acting in the longitudinal direction of the storage rack 2) that moves the bicycle BCL forward when the bicycle BCL is carried into the storage rack 2. It is arranged on the side where the lateral component force FS acts with respect to the longitudinal center line CL of the storage rack 2. That is, in the right swing type (FIG. 1) of the first example and the left swing type (FIG. 4) of the second example, the mounting position of the elevating brake 20 is symmetrical with respect to the longitudinal center line CL of the storage rack 2. It is set by sorting.

Regarding the right swing angle α (or left swing angle β), if the range is 15 ° ≦ α (or β) ≦ 60 ° (preferably, the range is 25 ° ≦ α (or β) ≦ 50 °). When the bicycle BCL is carried in, the elevating brake 20 has a great effect of stopping the lateral displacement of the storage rack 2. However, when the right swing angle α (or the left swing angle β) exceeds the upper limit value, the storage rack 2 may be nearly parallel to the fixed rail 4, making smooth lateral sliding difficult. Further, when the right swing angle α (or the left swing angle β) is lower than the lower limit value, the storage rack 2 becomes closer to an orthogonal state with respect to the fixed rail 4, and the lateral component force FS becomes relatively small, so that the carry-in Since lateral displacement itself is less likely to occur, there is a risk that it becomes less necessary to symmetrically set the mounting position of the elevating brake 20 (the cost increases compared to the effect).

As described above, except that the mounting position of the elevating brake 20 in the bicycle parking device 1 is different between the first example and the second example, each part of the caster 10, the elevating brake 20, the foot pedal 30, the return mechanism 40, and the rotary brake 50. The structure is common to the first example and the second example. Therefore, in the following description, the structure of the first example is used as a reference unless otherwise specified. Further, any of the front and rear wheels FW and RW can be carried in from the entrance / exit 2a of the storage rack 2, but in the following description, the front wheels are carried in (that is, the front wheels FW are used as the leading carry-in wheels and carried into the front wheel guard frame 2b. Only the case of carrying out from the rear wheel RW) will be described.

Returning to FIGS. 2 and 3, one or more (two in the figure) casters 10 are attached to the caster holding frame 11 fixed to the bottom surface side of the storage rack 2 between the entrance 2a and the elevating brake 20. Be done. Each caster 10 can roll laterally while supporting the storage rack 2 in the landing state.

The elevating brake 20 is arranged so as to be able to elevate and descend along the left side wall of the storage rack 2 adjacent to the entrance 2a and in the vicinity of the caster 10 (see FIGS. 7 and 11). The elevating brake 20 is in a state where the tip of the brake 20 touches the ground at a protruding position protruding below the lower edge of the caster 10 (see FIG. 9) and a state of standing by at a retracted position where the tip of the brake 20 retracts above the lower edge (see FIG. 13). ) And can be changed.

The foot pedal 30 is arranged in association with the elevating brake 20, and is artificially stepped on only to displace the elevating brake 20 from the retracted position to the protruding position (see FIG. 7). The return mechanism 40 returns the elevating brake 20 from the protruding position to the retracted position based on the loading of the bicycle BCL into the storage rack 2 (see FIG. 13).

Specifically, the return mechanism 40 includes a wheel receiver 41 arranged on the front end side of the storage rack 2, a rotating plate 42 (acting member) arranged on the rear end side of the storage rack 2, and a storage rack. A connecting rod 43 (connecting member) that is arranged in the longitudinal direction along the bottom wall of No. 2 and connects the wheel receiving 41 and the rotating plate 42, and a wheel receiving that is hung between the wheel receiving 41 and the storage rack 2. Includes a tension coil spring 44 (elastic member).

The wheel receiving tension coil spring 44 applies an urging force to the wheel receiving 41 in the direction in which the rotating plate 42 moves away from the elevating brake 20 (see FIG. 15). The wheel receiver 41 opposes the urging force of the wheel receiver tension coil spring 44 and rotates around the horizontal rotation shaft 41a by the front wheel FW of the bicycle BCL carried into the storage rack 2. The rotating plate 42 rotates around the vertical rotating shaft 42a in response to the rotation of the wheel receiver 41 around the horizontal rotating shaft 41a (see FIG. 11), and returns the lifting brake 20 in the protruding position to the retracted position. (Details will be described later).

Next, the detailed structure of the elevating brake 20 and the foot pedal 30 will be described with reference to FIGS. 7 and 8. The foot pedal 30 is attached to the storage rack 2 via the pedal mounting frame 31, and the pedal mounting frame 31 has a flat plate-shaped rack fixing portion 311 fixed to the left wall of the storage rack 2 and a left side from the rack fixing portion 311. It has a tubular portion 312 that protrudes in the vertical direction and penetrates in the vertical direction.

The foot pedal 30 is arranged on the left side of the storage rack 2 and is operated by being stepped on by an operator. The upper surface pressing portion 301 and the side supporting portion 302 extending downward from the front and rear edges of the upper surface pressing portion 301 in the front-rear direction, respectively. And, the whole is formed in a portal shape. In the side support portion 302, the linear connecting portion 221a and the bulging portion 221b that bulges from the upper end portion of the connecting portion 221a toward the storage rack 2 are overlapped with the link plate 221 formed in an L shape. They are arranged on the front, rear, and outer sides of the tubular portion 312, respectively. The upper portions of the pair of side support portions 302 are fixed to pedal rotation shafts 32 (for example, mounting bolts) that penetrate the peripheral wall of the tubular portion 312 in the front-rear direction. On the other hand, the lower portion of the side surface support portion 302 is rotatably connected to the L-shaped intermediate portion of the link plate 221 (that is, the upper end portion of the connecting portion 221a) around the connecting shaft 33 (for example, mounting bolt) in the front-rear direction.

A cylindrical elevating pipe 21 is inserted into the tubular portion 312 of the pedal mounting frame 31 so as to be able to elevate, and an elevating brake 20 is inserted / fixed at the lower end portion of the elevating pipe 21. The lower end of the connecting portion 221a of the link plate 221 is fixed to the plate rotating shaft 23 (for example, a mounting bolt), and the plate rotating shaft 23 penetrates the peripheral wall of the elevating pipe 21 in the front-rear direction and forms the peripheral wall of the tubular portion 312. It is inserted through the formed elongated hole 312b in the vertical direction. Therefore, when the plate rotating shaft 23 moves up and down along the elongated hole 312b, the lifting pipe 21 and the lifting brake 20 move up and down integrally with the plate rotating shaft 23. The protruding height of the elevating brake 20 with respect to the elevating pipe 21 may be adjustable.

A pedal tension coil spring 222 (elastic member) is hung between the pedal rotation shaft 32 and the plate rotation shaft 23, and the pedal tension coil spring 222 is inserted into the tubular portion 312 and the elevating pipe 21. On the front and rear outer peripheral surfaces of the tubular portion 312, an arc-shaped notch groove 312a (see FIG. 11) having a radius of the distance between the pedal rotation shaft 32 and the connecting shaft 33 about the pedal rotation shaft 32 is formed. It is formed. The notch groove 312a is filled with a lubricant such as grease, and the connecting shaft 33 is lubricated each time the head portion of the connecting shaft 33 rushes into the notch groove 312a. Therefore, the side support portion 302 of the foot pedal 30 and the link plate The connecting portion 221a of 221 can smoothly rotate relative to each other for a long period of time.

As shown in FIGS. 7 and 8, when the operator steps on the upper surface pressing portion 301 and the foot pedal 30 rotates downward with respect to the pedal rotation shaft 32, the connecting shaft 33 is pushed out to the storage rack 2 side. The plate rotation shaft 23 descends along the elongated hole 312b. As a result, the pedal tension coil spring 222 spanned by the pedal rotation shaft 32 and the plate rotation shaft 23 is stretched to generate the maximum deflection (that is, the spring force of the maximum tension load is generated).

Further, at this time, the connecting shaft 33 (or the connecting portion 221a of the link plate 221) is a straight line VL (cylindrical portion 312, the elevating pipe 21 and the tension coil spring for the pedal) connecting the pedal rotating shaft 32 and the plate rotating shaft 23. It is positioned (that is, beyond the dead center) slightly off the storage rack 2 side (right side in the figure) from the center line common to 222 and forming a vertical line. As a result, the foot pedal 30 is locked in the depressed state, and the elevating brake 20 is locked in the protruding position. As described above, the link plate 221 and the tension coil spring 222 for the pedal form a dead center crossing mechanism 22 (holding mechanism) for locking the elevating brake 20 to the protruding position and holding the ground contact state. When the foot pedal 30 is depressed, the bulging portion 221b of the link plate 221 greatly protrudes into the space below the storage rack 2.

As shown in FIGS. 10 to 13, when the bicycle BCL is carried into the storage rack 2, the wheel receiver 41 is rotated around the horizontal rotation shaft 41a by the front wheel FW, and the rotation plate 42 is rotated around the vertical rotation shaft 42a. It rotates and pushes back the bulging portion 221b of the link plate 221. In this way, when the bicycle BCL is carried in, the lock of the foot pedal 30 in the depressed state (lock at the protruding position of the elevating brake 20) is released by the dead center crossing mechanism 22, and the elastic force of the pedal tension coil spring 222 (that is, that is). The elevating brake 20 returns to the retracted position (standby state) by the pulling force).

Returning to FIGS. 2 and 3, the rotary brake 50 is composed of a rectangular flat plate-shaped contact plate 51 arranged so as to project to the left from the rear end of the storage rack 2 in a plan view. The rotary brake 50 is attached to the rear side of the elevating brake 20 and the caster 10 and to the front side adjacent to the doorway 2a.

Specifically, the contact plate 51 is cantileveredly supported by the central shaft 51a arranged along the longitudinal center line CL on the bottom surface side of the storage rack 2, and is rotatable around the central shaft 51a. is there. The contact plate 51 is urged in a direction in which the free end portion is always away from the ground surface E (that is, upward) by a return torsion coil spring 52 (biasing member) wound around the central shaft 51a and attached to the contact plate 51. Has been done.

Therefore, the contact plate 51 is in a contact state in which the lower surface is pressed against the ground surface E against the urging force of the return torsion coil spring 52 by an artificial stepping operation (see FIGS. 10, 14, and 18). It is possible to change to a non-contact state (see FIGS. 9, 13, and 17) in which the return torsion coil spring 52 receives the urging force of the return torsion coil spring 52 and separates from the ground surface E by artificially releasing the stepping operation. Further, when the elevating brake 20 is in the protruding position (grounded state), the contact plate 51 is stepped on to bring it into a contact state (see FIG. 10), and the stepping operation is released to bring it into a non-contact state (see FIG. 10). (See FIG. 9) is possible. Further, when the evacuation brake 20 is in the retracted position (standby state), the contact plate 51 can be brought into a contact state (see FIGS. 14 and 18) and a non-contact state (see FIGS. 13 and 17). Is.

When the bicycle BCL is taken in and out, the storage rack 2 has irregularities such as rolling motion (that is, rolling vibration around the longitudinal center line CL) and torsional deformation caused by the lateral component force FS described above. Movement is likely to occur. At this time, if the lift brake 20 is in the retracted position, the braking function is not exerted, and even if the lift brake 20 is in the protruding position, the braking function is diminished, which causes harm to the storage rack 2, the bicycle BCL, the user, and the like. May reach. By preventing or suppressing these irregular movements generated in the storage rack 2 by the rotary brake 50, the bicycle BCL can be taken in and out more safely.

In addition, when the user feels irregular shaking of the bicycle BCL or storage rack 2 during loading / unloading work or lateral sliding movement, the rotation brake 50 can be immediately operated to avoid danger and irregular shaking. As soon as the above is settled, the operation of the rotary brake 50 can be released to return to the work of putting in and taking out the bicycle BCL or the lateral sliding movement of the storage rack 2. As described above, since the braking function of the rotary brake 50 is exerted only while the user is operating, the safety and operability are excellent. Further, since the rotary brake 50 is arranged adjacent to the wheel entrance / exit 2a, when the user feels irregular shaking of the bicycle BCL or the storage rack 2 during the loading / unloading work, the bicycle BCL is immediately taken in / out. Since the rotation brake 50 can be operated by interrupting the operation, danger can be quickly avoided.

Most users stand on the left side of the bicycle BCL to put in and take out the bicycle BCL. Therefore, even in the left swing type of the second example, the rotary brake 50 is used at the entrance / exit 2a of the storage rack 2 so that the user who senses irregular shaking of the bicycle BCL or the storage rack 2 can easily operate the bicycle BCL or the storage rack 2 at a moment's notice. It is located on the left side of the vicinity (see FIG. 5).

Next, the operation of the right-swing type bicycle parking device 1 described above will be outlined in accordance with the order of operations shown in FIGS. 7 to 18.

<Storing rack empty state, lifting brake 20 protruding position> (Figs. 7 to 9)
The lifting brake 20 is displaced to the protruding position (moves to the ground contact state) by the stepping operation of the foot pedal 30, the foot pedal 30 is locked to the stepping state by the operation of the dead point crossing mechanism 22, and the lifting brake 20 is in the protruding position (grounding state). ) Is locked. When the caster 10 shifts from the landing state to the floating state and the bicycle BCL is carried in from the doorway 2a, the lateral displacement of the storage rack 2 is stopped.

<Operating the rotary brake 50 while carrying in the bicycle BCL> (Fig. 10)
When the elevating brake 20 is in the protruding position (grounded state) and irregular movement occurs during the loading of the bicycle BCL, the contact plate 51 is stepped on to enter the contact state. When the irregular movement ends, the stepping operation of the contact plate 51 is released and the state returns to the non-contact state (FIG. 9).

<Bicycle BCL carry-in end, evacuation brake 20 retract position> (Figs. 11 to 13)
When the bicycle BCL is brought in, the dead center crossing mechanism 22 that locks the foot pedal 30 in the depressed state (locks the elevating brake 20 at the protruding position) is released, and the elevating brake 20 is retracted by the elastic force of the tension coil spring 222 for the pedal. Return to the position (standby state). The caster 10 returns to the landing state, and the storage rack 2 can slide laterally along the fixed rail 4.

<Operation of the rotary brake 50 while the storage rack 2 is sliding sideways> (Fig. 14)
When an irregular movement occurs while the storage rack 2 is laterally slid along the fixed rail 4, the contact plate 51 is stepped on to enter a contact state. When the irregular movement ends, the stepping operation of the contact plate 51 is released and the state returns to the non-contact state (FIG. 13).

<Evacuation position of lifting brake 20, start of carrying out bicycle BCL> (Figs. 15 to 17)
When the elevating brake 20 starts carrying out the bicycle BCL in the retracted position (standby state) and the front wheel FW rotates the wheel receiver 41 backward, the rotating plate 42 rotates around the vertical rotating shaft 42a and returns to the initial position. The state is maintained by the urging force of the wheel receiving tension coil spring 44. Further, the operation of the dead center crossing mechanism 22 is still released, and the evacuation brake 20 is held in the retracted position (standby state).

<Operating the rotary brake 50 while carrying out the bicycle BCL> (Fig. 18)
When the lifting brake 20 is in the retracted position (standby state) and irregular movement occurs while the bicycle BCL is being carried out, the contact plate 51 is stepped on to enter the contact state. When the irregular movement ends, the stepping operation of the contact plate 51 is released and the state returns to the non-contact state (FIG. 17).

In addition to the operation of the bicycle parking device 1 described above, the bicycle BCL can be carried in while the evacuation brake 20 is in the retracted position (standby state) and the caster 10 is in the landing state (see FIG. 17). Further, when the elevating brake 20 is in the retracted position (standby state) and irregular movement occurs during the loading of the bicycle BCL, the contact plate 51 is stepped on to enter the contact state (see FIG. 18). When the irregular movement ends, the stepping operation of the contact plate 51 is released and the contact plate 51 returns to the non-contact state (see FIG. 17).

Further, when the foot pedal 30 is depressed in the actual vehicle state, the elevating brake 20 is temporarily displaced to the protruding position (moves to the ground contact state). However, since the bulging portion 221b of the link plate 221 is blocked by the rotating plate 42, the dead center crossing mechanism 22 does not operate, and when the depression of the foot pedal 30 is interrupted, the elastic force of the tension coil spring 222 for the pedal Immediately returns to the retracted position (standby state) (see FIGS. 11 to 13).

In this way, the elevating brake 20 is arranged on the acting side of the lateral component FS, is displaced to the protruding position on the acting side, and is fixed by receiving the lateral component FS generated when the bicycle BCL is carried in. Even if the braking force is not directly applied to the rail 4 and the auxiliary wheel 10, it is possible to reliably prevent the storage rack 2 from laterally shifting when the bicycle BCL is carried in. Therefore, the positional relationship (direction of intersection and angle of intersection) of the diagonal intersection between the fixed rail 4 and the storage rack 2 is arbitrarily set according to the shape and size of the bicycle parking space in which the bicycle parking device 1 is installed. Is possible. Further, by preventing or suppressing the irregular movement of the storage rack 2 by the rotary brake 50, the bicycle BCL can be taken in and out more safely.

As described above, in the actual vehicle state, it is impossible to maintain the caster 10 in the floating state even if the foot pedal 30 is depressed (that is, the foot pedal 30 is substantially impossible to be depressed). At this time, since the storage rack 2 can be slid laterally along the fixed rail 4, the bicycle parking work in the actual vehicle state can be efficiently performed.

The present invention relates to any of the outdoor bicycle parking lots permanently installed on sidewalks, parks, etc., indoor bicycle parking lots established in condominiums, apartments, etc., and underground bicycle parking lots attached to buildings, underground stations, etc. It can also be applied to bicycle parking devices. It should be noted that the upper and lower two-stage bicycle parking machine can also be applied to the lower bicycle parking device.
