Abstract

PURPOSE:To reduce labor for lifting a mounting base on which a bicycle is put CONSTITUTION:A mounting base 5 is pulled out from a fixed base 4 and is rotated around a supporting shaft 20 in a guiding carriage 6 by its self-weight so as to be inclined. A lifting arm 24 is rotated at the same time, and a spring bracket 31 is moved toward a pressing plate 30, so that a spring 22 is compressed. When the mounting base 5 is rotated and moved to the lowermost end, a toggle mechanism 25 is pressed by means of an arm 21 so as to be linearly arranged. When the toggle mechanism 25 is linearly arranged, the pressing plate 30 is moved to the spring bracket 31, and the spring 22 is compressed further and its spring force is increased. As a result, force stored in the spring 22 is strengthened further, so that less force is required for lifting the mounting base 5 when the mounting base 5, on which a bicycle is put, is lifted and pushed in, and consequently, labor is reduced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a three-dimensional parking apparatus for two-wheeled vehicles such as bicycles, mini-bikes, motorcycles, etc., which can be parked in two stages.

[0002]

2. Description of the Related Art Conventionally, as a parking device capable of efficiently parking a two-wheeled vehicle such as a bicycle by effectively utilizing a limited parking space, for example, a two-tiered parking system as shown in FIG. A three-dimensional parking device for a motorcycle which secures a space is known (for example, Japanese Patent Publication No. 60-5094).
No. 6 publication). This type of three-dimensional parking device for a motorcycle includes a standing pillar (not shown), a fixed base 50 having one end fixed to the pillar so as to vertically divide a lower parking space 48 and an upper parking space 49, and a motorcycle. It can be placed and is slidable on the fixed base 50. When the tip portion is located at one end of the fixed base 50, it is in a stored state and slides on the fixed base 50 so that the tip portion is fixed. The mounting base 51 is rotated about the other end of the fixed base 50 to reach the other end of the mounting base 51 in an inclined state.

In storing the bicycle in the upper parking space 49 of the above-mentioned three-dimensional parking apparatus for a motorcycle, first, the mounting base 51 is pulled out along the fixed base 50, and the mounting base 51 is inclined, and the bicycle is tilted. 52 is mounted on the mounting base 51. Then the mounting base 5
1 is lifted up to a substantially horizontal state, and then the mounting base 5
1 is pushed toward the support along the fixed base 50. In this way, the bicycle is stored in the upper parking space 49.

By the way, in this type of three-dimensional parking apparatus for two-wheeled vehicles, the mounting base 51 cannot be moved horizontally unless the bicycle 52 is placed on the mounting base 51 and the total weight is lifted to a predetermined height. This is quite a problem, especially for weak people such as children. Therefore, in order to enable the lifting operation of the mounting base 51 on which the bicycle 52 is placed to be carried out lightly, various energy storage assisting devices that utilize the force of the spring as an assisting force have been conventionally developed. For example, in the energy storage auxiliary device 55 shown in FIG. 7, one end b of the spring 53 is attached to the mounting base 51, and the spring 53
The other end a of the guide carriage 54 slidable on the fixed base 50
It is attached to. A straight line c connecting the connection point a between the spring 53 and the guide carriage 54 and the relative rotation center point d between the guide carriage 54 and the mounting base 51 tilts the mounting base 51 so that its base is located in the lower parking space. It is set so that the base end portion of the mounting base 51 comes close to the grounded state side within the rotation range of the state in which the floor surface of 48 is grounded and the mounting base 51 is rotated to the horizontal position. There is. Therefore, in the inclined state where the base end of the mounting base 51 is grounded, the spring force acts in the direction of pressing the mounting base 51 against the ground,
When the mounting base 51 is slightly lifted, the spring force acts in the direction of lifting the mounting base 51. In this power storage assisting device 55, when the mounting base 51 in an inclined state is lifted, if it is lifted a little, then the assisting force of the spring 53 acts in the direction of lifting the mounting base 51, so that the mounting base 51 is mounted with a light force. The mounting base 51 can be lifted.

[0005]

However, the force assisting device 55 is constructed so that the spring force acts in the direction of lifting the mounting base 51 only when the mounting base 51 is slightly lifted. Therefore, the function as the energy storage auxiliary device does not work unless the mounting base 51 is slightly lifted first. That is, the mounting base 51
In the inclined state where the base end of the mounting base 51 is in contact with the ground, the spring force acts in the direction of pressing the mounting base 51 against the ground. Therefore, in the initial stage of lifting the mounting base 51, the spring force is not resisted. As much as the mounting base 51 has to be lifted up, a rather large force is required. Therefore, in the above-described three-dimensional parking apparatus for a motorcycle, it is necessary to solve the problem that the assisting force is always obtained when the mounting base 51 is lifted.

In the power storage assisting device 55, one end of a spring 53 is attached to the mounting base 51, and the other end of the spring 53 is attached to a guide carriage 54 which is slidable on the fixed base 50. If the length of 53 is not very long, it does not function as a power storage auxiliary device. Moreover, in the energy storage assist device 55, one end of the spring 53 attached to the mounting base 51 is largely displaced as the inclination angle of the mounting base 51 changes. Therefore, if the spring 53 is covered with a cover for safety, it is necessary to provide a large cover, which causes a problem of increasing the size of the entire parking device or narrowing the parking space. Therefore, in the above-mentioned three-dimensional parking apparatus for motorcycles, the development of a compact storage assisting apparatus that generates a large assisting force is an issue.

An object of the present invention is to solve the above-mentioned problems, and a mounting base on which a two-wheeled vehicle is mounted by mounting a small power storage auxiliary device capable of generating a large auxiliary force by using a small spring. A three-dimensional parking device for motorcycles that is configured to be able to always be lifted up lightly and has a spring force maintained until the mounting base on which the motorcycle is mounted is stored in a predetermined position to reduce the labor for housing the motorcycle. Is to provide.

[0008]

In order to achieve the above object, the present invention is configured as follows. That is, the present invention includes an upright pillar, a fixed base whose one end is fixed to the pillar so as to vertically divide a lower parking space and an upper parking space, and a link mechanism slidable on the fixed base. When the tip end is located at one end of the fixed base, the other end of the fixed base is moved as the tip moves to the other end of the fixed base by sliding on the fixed base from the stored state. A mounting base that can mount a two-wheeled vehicle that rotates from a center to a substantially horizontal state and a storage force assisting device that applies an auxiliary force for rotating the mounting base from the inclined state to a substantially horizontal state. The storage assist device stores the increasing spring force by compressing a spring in response to an increase in an inclination angle of the mounting base with respect to the fixed base, and the storage assist device includes the storage base. A toggle mechanism inclination angle for holding a spring force increased and further increase the spring force exceeds a predetermined value,
And a spring force releasing means for releasing the spring force held by the toggle mechanism at the accommodation position of the fixed base of the placement base.

Further, in this three-dimensional parking apparatus for a motorcycle, the storage assist device is compressed by the weight of the mounting base when the mounting base changes from a substantially horizontal state to an inclined state, and the front side in the inclined state. It is set so that the spring force can be increased by further compressing with the load placed on the writing base. Alternatively, the storage assist device is compressed by the dead weight of the mounting base when the mounting base changes from a substantially horizontal state to a tilted state, and a load such as a motorcycle is not placed in the tilted state. The load of the mounting base and the spring force of the spring are set to be balanced.

Further, in the three-dimensional parking apparatus for a two-wheeled vehicle, the above-mentioned mounting base is connected to a guide carriage that slides on the fixed base, and the power storage auxiliary device is attached to the guide carriage. In addition, the power storage auxiliary device includes a support member that supports the spring in an expandable and contractible manner and a support member that is attached to the guide carriage and the mounting base when the mounting base rotates from a substantially horizontal state to an inclined state. And a lifting arm that compresses the spring in conjunction with the rotation of the base and that applies the spring force of the compressed spring to the mounting base.

Further, in this three-dimensional parking apparatus for a two-wheeled vehicle, the spring force releasing means includes a protrusion provided on the toggle mechanism and an abutment provided on the fixed base that abuts the protrusion and bends the toggle mechanism. And a part. Further, the spring is composed of a double structure spring composed of an outer spring and an inner spring inserted into the outer spring.

[0012]

The three-dimensional parking apparatus for a motorcycle according to the present invention, which is configured as described above, operates as follows. That is, in this three-dimensional parking apparatus for two-wheeled vehicles, the power storage auxiliary device can store the increased spring force by compressing the spring in response to the increase in the inclination angle of the mounting base with respect to the fixed base. When the inclination angle of the placement base exceeds a predetermined value, the auxiliary device further enhances the spring force by the toggle mechanism, and the enhanced spring force is held by the toggle mechanism. Since the spring force held by the toggle mechanism can be released by the spring force releasing means in the accommodation position of the fixed base, when the load is placed on the mounting base in the inclined state, the mounting base is fixed to the fixed base. The tilt angle with respect to the base rotates over a predetermined value via the link mechanism, and a large assist force is accumulated. Moreover, a part of the spring force is held by the toggle mechanism and is held until the placement base is housed in a predetermined place, which can reduce the labor for housing the placement base.

In this three-dimensional parking apparatus for a motorcycle, particularly when a mounting base on which a motorcycle such as a bicycle is mounted is lifted, the inclination angle of the mounting base becomes smaller with respect to the fixed base. As the point of action at the fulcrum of inclination moves and changes, the mounting base can be pushed onto the fixed base, and the total load of the mounting base and the two-wheeled vehicle moves toward the fixed base. Therefore, the load of manually lifting the above-described placement base is reduced, and the labor is reduced. Therefore, when the mounting base on which a motorcycle such as a bicycle is mounted is lifted, the lifting force is small due to the action of the auxiliary force of the energy storage auxiliary device, and the mounting base and the motorcycle can be lifted lightly.

Further, in this three-dimensional parking apparatus for a motorcycle, the storage assist device is compressed by the dead weight of the mounting base when the mounting base shifts from the substantially horizontal state to the inclined state, and the motorcycle in the inclined state. Since it is possible to set the load of the mounting base and the spring force of the spring in a state where no load such as the above is placed, it is possible to balance the spring force of the spring. Even if it does not exist, the above-mentioned mounting base slowly tilts from its substantially horizontal state under its own weight to become an inclined state. Moreover,
With the rotation of the mounting base, the spring is automatically compressed and the spring force is accumulated.

Alternatively, the storage assisting device compresses the mounting base by its own weight when the mounting base changes from a substantially horizontal state to an inclined state, and mounts the two-wheeled vehicle on the mounting base in the inclined state. Sometimes it can be set to use the force of the compressed spring as an auxiliary force, so when parking the bicycle, you can pull out the mounting base and slowly move it from its horizontal state to its own weight without doing anything. The spring is automatically compressed by the rotation of the mounting base and the spring force is accumulated with the rotation of the mounting base, and the two-wheeled vehicle is placed on the mounting base in the tilted state. Then, the mounting base is further rotated by the weight of the bicycle, the spring is further compressed, and the spring force becomes stronger. Therefore,
When the mounting base on which the two-wheeled vehicle is mounted is lifted, the lifting force is small due to the action of the assisting force of the energy storage auxiliary device, and the mounting base can be lifted lightly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a three-dimensional parking apparatus for a motorcycle according to the present invention will be described below with reference to the drawings. FIG. 1 is a side view showing the overall appearance of the three-dimensional parking apparatus for a motorcycle. As shown in FIG. 1, this three-dimensional parking apparatus for a motorcycle has a fixed base in which one end is fixed to an upper part of the pillar 1 so as to vertically partition a vertically arranged pillar 1, a lower parking space 2 and an upper parking space 3. 4 and a two-wheeled vehicle can be placed on the fixed base 4 so as to be slidable. When the tip portion is located at one end of the fixed base 4, the storage state is established, and the tip end is slid on the fixed base 4. A mounting base 5 is provided, which turns around the other end of the fixed base 4 to be inclined when the portion reaches the other end of the fixed base 4. A guide carriage 6 is slidably provided on the fixed base 4. One end of the mounting base 5 is connected to the guide carriage 6, and the mounting base 5 slides on the fixed base 4 while being guided by the guide carriage 6. Further, the guide cart 6 has a built-in energy storage assisting device 7 that generates an assisting force when the mounting base 5 is lifted.

In this three-dimensional parking apparatus for motorcycles, a plurality of pillars 1 are erected from a concrete floor surface 8, a fixed base 4 is horizontally arranged above each pillar 1, and two parking spaces are provided vertically. And a lower parking space 2 and an upper parking space 3 are formed. Support 1 and fixed base 4
Are arranged at predetermined intervals so that a large number of motorcycles can be parked side by side without interfering with each other.

The three-dimensional parking apparatus for a motorcycle will be described in more detail. 2 is an enlarged side view of the three-dimensional parking device for a motorcycle in an inclined state, FIG. 3 is a sectional view taken along the line AA of FIG. 2, FIG. 4 is a sectional view taken along the line BB of FIG. 2 is a sectional view taken along the line CC of FIG. 2, and FIG. 6 is an enlarged side view of the three-dimensional parking apparatus for a motorcycle in a stored state.

The fixed base 4 is a sturdy beam member having a rectangular cross section, and a guide carriage 6 is slidably provided on the fixed base 4. A stopper 9 is provided at the tip of the fixed base 4 in order to prevent the guide carriage 6 from falling off the fixed base 4. A support roller 1 for supporting the lower surface of the mounting base 5 is provided at the tip of the fixed base 4.
0 is attached.

The guide carriage 6 includes a pair of side plates 11 and 11 arranged so as to face each other so as to sandwich the fixed base 4 from both sides.
Rollers 12 and 13 attached to the side plates 11 and 11,
It has a power storage assisting device 7 that generates an assisting force for lifting the mounting base 5. The rollers 12 and 13 are composed of an upper roller 12 rolling along the upper surface of the fixed base 4 and a lower roller 13 rolling along the lower surface of the fixed base 4.
The upper roller 12 is arranged in front of and behind the guide carriage 6,
Each upper roller 12 is rotatably supported by a single mandrel 14 fixed to both side plates 11, 11. The lower rollers 13 are arranged in front of and behind the guide carriage 6 so as to face the upper rollers 12, and each lower roller 13 is attached to each side plate 11, 1.
It is rotatably supported by a mandrel 15 which is cantilevered at 1. Both the upper roller 12 and the lower roller 13 have flange portions 16 and 17, and the guide carriage 6 is restrained vertically and horizontally with respect to the fixed base 4 by these rollers 12 and 13, and It can slide smoothly in the longitudinal direction.

The mounting base 5 is a channel-shaped elongated steel member, and a handle 18 is attached to the base end thereof. The bicycle tire is placed on this channel-shaped part. Although illustration is omitted, the mounting base 5 is provided with a front wheel receiving frame, a rear wheel receiving frame, a fall prevention mechanism, and the like in order to prevent the bicycle from falling or falling. The tip of the mounting base 5 is connected to the guide carriage 6. The connection relationship between the mounting base 5 and the guide carriage 6 will be described. A connecting member 19 is integrally provided at the tip of the mounting base 5, and the connecting member 19 is a side plate 11 of the guide carriage 6.
It is fixed to one end of a support shaft 20 rotatably supported by 11. An arm 21 is integrally fixed to the other end of the support shaft 20. Therefore, when the connecting member 19 rotates about the support shaft 20, that is, when the tilt angle of the mounting base 5 changes, the arm 21 also integrally rotates about the support shaft 20.

A power storage assisting device 7 is incorporated between both side plates 11 of the guide cart 6. When the support member 23 that supports the spring 22 in a stretchable manner and is attached to the side plates 11 of the guide carriage 6 and the mounting base 5 rotate from a substantially horizontal state to an inclined state, the power storage auxiliary device 7 generally extends and contracts. When the mounting arm 5 is rotated more than a predetermined angle in the inclined state, the spring 22 is compressed in conjunction with the mounting arm 5 and the force of the compressed spring 22 is applied to the mounting base 5, and the mounting base 5 is rotated at a predetermined angle or more. The toggle mechanism 25 further compresses the spring 22 in conjunction with the rotation of the.

The support member 23 is a side plate 11, 1 of the guide carriage 6.
1, a guide block 26 fixed to the guide block 26, a rod 28 slidably inserted in a through hole 27 formed in the center of the guide block 26, and a pressing plate 30 engaging with a step portion 29 formed on the rod 28. And a U-shaped spring receiver 31 arranged to face the pressing plate 30. Between the pressing plate 30 and the spring receiver 31, a double-structured spring 22 in which an inner spring 22b having a small diameter is inserted into an outer spring 22a having a large diameter is mounted. The rod 28 includes a large diameter portion 32 and a small diameter portion 33, and the outer spring 22 a is provided outside the large diameter portion 32.
Since the inner spring 22b is inserted inside the large diameter portion 32, both springs 22a and 22b do not interfere with each other. The double structure spring 22 has an advantage that a small spring can obtain a large spring force. Further, since the spring 22 is housed between the side plates 11 of the guide carriage 6, it is not necessary to attach a cover to cover the spring.

The lifting arm 24 is composed of two L-shaped arms 34, 34 which constitute a link mechanism. Each L-shaped arm 34 has a short arm portion 35 having a short length, a long arm portion 36 having a long length in which the central portion is slightly bent, and a connecting portion 37 in which both arm portions 35, 36 are connected at a substantially right angle. It consists of and. Both L-shaped arms 3
4, 34, the tip of the short arm portion 35 is pivotally attached to the spring bearing 31 of the support member 23, and the connecting portion 37 is pivotally attached to the shaft 38 fixed to both side plates 11, 11 of the guide carriage 6. ing. When the long arm portion 36 rotates from the substantially horizontal state to the inclined state as shown in FIG. 2, the spring receiver 31 moves to the left, and the spring 22 contracts accordingly. On the contrary, when the long arm portion 36 is changed from the inclined state to the substantially horizontal state, the spring receiver 31 moves to the right and the spring 22 is extended as shown in FIG. A support roller 39 is attached to the tip of the long arm portion 36 so that the support roller 39 is sandwiched between the long arm portions 36 from both sides. Support roller 39
Supports the mounting base 5 by constantly contacting the bottom surface of the mounting base 5. An arcuate recess 40 is formed in the center of the long arm portion 36. This arcuate recess 40
As shown in FIG. 2, the upper roller 12 of the guide carriage 6 fits when the mounting base 5 is in an inclined state.

Then, in this three-dimensional parking apparatus for motorcycles,
When the mounting base 5 on which a two-wheeled vehicle such as a bicycle is mounted is lifted, the fulcrum of inclination of the mounting base 5, that is, the point of action on the shaft 38, changes, in other words, the inclination angle of the mounting base 5 decreases. Accordingly, the inclination angles of the short arm portion 35 and the long arm portion 36 change, and the shaft 38, which is the pivot point of the short arm portion 35 and the long arm portion 36, is changed.
As the position of the mounting base 5 moves and the inclination angle of the mounting base 5 becomes smaller, the mounting base 5 can be pushed into the fixed base 4 and the load of lifting the load between the mounting base 5 and the two-wheeled vehicle by human power can be increased. Is smaller and labor is reduced.

In the three-dimensional parking apparatus for a motorcycle, the toggle mechanism 25 is composed of a first link 42 and a second link 43 which are connected to each other via a connecting pin 41. The first link 42 is an L-shaped link and is rotatably attached to a fixing pin 44 fixed to the side plates 11 of the guide carriage 6, and the second link 43 is a pressing plate 30.
It is pivotally attached to the movable pin 45 by means of As shown in FIG.
When the toggle mechanism 25 is bent in a dogleg shape at the connecting portion 46 of the first link 42 and the second link 43,
The pressing plate 30 is in contact with the guide block 26. On the other hand, when the toggle mechanism 25 extends linearly,
As shown in FIG. 5, the pressing plate 30 is separated from the guide block 26 and moves toward the spring receiver 31 together with the rod 28 to compress the outer spring 22a and the inner spring 22b and further increase the spring force.

As shown in FIG. 2, in the toggle mechanism 25, the connecting portion 46 of the first link 42 and the second link 43 is pressed by the arm 21 which rotates integrally with the mounting base 5, so that the linear mechanism is linearly moved. Grows in shape. The toggle mechanism 25, which once extends linearly, moves from the connecting portion 46 to the arm 2
The linear state is maintained even if 1s are separated. Therefore, in order to return the toggle mechanism 25 to the bent state in the dogleg shape as shown in FIG. 6, it is necessary to push the free end 47 of the L-shaped first link 42. Although not shown, a member for pushing the free end 47 of the first link 42 is provided on, for example, the column 1, and the first link 42 is free when the guide carriage 6 reaches the column 1 in a stored state. The end 47 is pushed, and the toggle mechanism 25 returns to the doglegged state.

The strength of the spring 22 may be appropriately selected. For example, a spring having a spring force that is substantially equal to the weight of the mounting base 5 can be used. In particular, spring 2
It is preferable that the strength of 2, that is, the spring force, be such that the mounting base 5 is slowly inclined by its own weight only by pulling out the mounting base 5, and the spring 22 is naturally compressed. Also,
The spring force of the spring 22 is such that the arm 21 fixed to the mounting base 5 is in contact with the toggle mechanism 25 when the spring 22 is compressed by the weight of the mounting base 5, but at this stage. The strength of the toggle mechanism 25 is preferably still unchanged.

Next, the operation of the three-dimensional parking apparatus for a motorcycle will be described. In the stored state, the mounting base 5 is in a substantially horizontal state, so that the arm 21 that rotates together with the mounting base 5 is separated from the toggle mechanism 25.
Further, the spring force releasing means is a protrusion 47A provided on the free end 47 of the first link 42 of the toggle mechanism 25 and an abutment portion provided on the fixed base 4 that abuts against the protrusion 47A and bends the toggle mechanism 25. (Not shown). Therefore, the protruding portion 47A is fixed to the fixed base 4 or the pillar 1.
When pushed by the abutting portion attached to the toggle mechanism 25, the toggle mechanism 25 is bent in a dogleg shape as shown in FIG. 6, and the spring force held by the toggle mechanism 25 is released. Therefore, since the pressing plate 30 is in contact with the guide block 26 and the lifting arm 24 is in a substantially horizontal state, the spring 22 is in an extended state.

When the bicycle is parked, the mounting base 5 in the storage position is pulled out by the handle 18. Since the guide carriage 6 is supported on the fixed base 4 by the rollers 12 and 13, and the mounting base 5 is supported by the guide carriage 6 and the support rollers 10 attached to the fixed base 4, the mounting base 5 is The force required to pull it out is small. When the mounting base 5 is pulled out, the mounting base 5 moves together with the guide carriage 6 on the fixed base 4 toward the other end of the fixed base 4. As the mounting base 5 approaches the other end of the fixed base 4, the mounting base 5 rotates around the support shaft 20 of the guide carriage 6 under its own weight. The lifting arm 24 also rotates together with the rotation of the mounting base 5. With the rotation of the lifting arm 24, the spring receiver 31 moves toward the pressing plate 30, so that the spring 22 is compressed (compression at this time is referred to as "first-stage compression"). . At this time, the arcuate recess 40 of the lifting arm 24 is fitted to the upper roller 12 of the guide carriage 6, and the mounting base 5 is stabilized in an inclined state.

Next, the bicycle is placed on the inclined mounting base 5. Along with that, the mounting base 5 is further rotated by the weight of the bicycle, and the arm 21 fixed to the mounting base 5 strongly pushes the toggle mechanism 25.
Becomes straight. The linear movement of the toggle mechanism 25 causes the pressing plate 30 to move toward the spring receiver 31, and accordingly the spring 22 is further compressed (compression at this time is referred to as "second stage compression"). I will call it). As a result, the force accumulated in the spring 22 becomes stronger, and the strength becomes larger than the own weight of the mounting base 5. In order to obtain this second stage of compression, you have to push down the mounting base with great force, but if you use the weight of the bicycle,
Pushing down of the mounting base is done automatically. It should be noted that the base end of the mounting base 5, that is, the end of the mounting base 5 on the side where the handle 18 is attached, contacts the concrete floor surface 8 only when the bicycle is mounted on the mounting base 5. It's okay, but you don't have to touch the concrete floor when you put your bike on.

The bicycle mounted on the mounting base 5 does not drop or fall down, so that the front wheel receiving frame, the rear wheel receiving frame,
It is fixed by a fall prevention mechanism. Then, the handle 18 of the mounting base 5 is held and the mounting base 5 is lifted together with the bicycle. At this time, since the auxiliary force of the spring 22 works, the force required to lift the mounting base 5 can be reduced by the amount of the spring force. That is, when the assisting force of the spring 22 does not work, a force sufficient to lift the total weight of the bicycle and the mounting base 5 is required, but when the assisting force of the spring 22 works, the mounting base 5 Since the weight of the bicycle is almost offset by the spring force accumulated by the first-stage compression, and the weight of the bicycle is almost offset by the spring force accumulated by the second-stage compression, the force required to lift the mounting base 5 is It can be quite small. As the mounting base 5 approaches a substantially horizontal state, the lifting arm 24 rotates and the spring receiver 31 moves away from the pressing plate 30. On the other hand, the arm 21 separates from the toggle mechanism 25, but the toggle mechanism 25 remains linear, so the pressing plate 30
The position of does not change.

When the mounting base 5 is in a substantially horizontal state, the mounting base 5 may be pushed toward the support 1. No great force is required when pushing the mounting base 5. The mounting base 5 supported by the guide carriage 6 and the support roller 10 is
It moves smoothly toward the pillar 1 together with the guide carriage 6.
When the guide carriage 6 reaches the pillar 1, the protrusion 47A provided on the toggle mechanism 25 abuts on the contact portion provided on the pillar 1, and the spring force of the toggle mechanism 25 is released, and the toggle mechanism 2 is released.
5 again bends like a dogleg, and the stored force of the spring 22 is completely released.

EFFECTS OF THE INVENTION Since the three-dimensional parking apparatus for a motorcycle according to the present invention is constructed as described above, it has the following effects. That is, in this three-dimensional parking apparatus for two-wheeled vehicles, the power storage auxiliary device accumulates the spring force, that is, the auxiliary force, which gradually increases until the inclination angle of the mounting base reaches a predetermined value,
When the tilt angle of the mounting base exceeds a predetermined value, the spring force is further increased by the toggle mechanism, and the increased spring force is stored in the toggle mechanism. When the two-wheeled vehicle is mounted on the base, the mounting base rotates with the inclination angle exceeding a predetermined value, and a large assist force is accumulated. Therefore, when lifting the mounting base on which the two-wheeled vehicle is mounted, the lifting force may be small due to the auxiliary force of the energy storage auxiliary device, and the mounting base may be pushed into the fixed base as the mounting base is raised. You can
Since the load is loaded on the fixed base, the mounting base on which the motorcycle is mounted can be lifted lightly. Moreover, since a part of the spring force is held by the toggle mechanism until the placement base is housed in the fixed base at the predetermined position, the placement base can be housed in the fixed base. Until the completion, the assisting force works effectively, and the effort for housing the two-wheeled vehicle can be reduced.

Further, in the three-dimensional parking apparatus for a motorcycle according to the present invention, the energy storage auxiliary device compresses by the dead weight of the mounting base when the mounting base changes from the substantially horizontal state to the inclined state, and in the inclined state. If the setting is made so that the force of the spring that is further compressed when the motorcycle is placed on the mounting base is used as an auxiliary force, the parking can be parked when the mounting base is pulled out. From the substantially horizontal state, the mounting base is slowly rotated by its own weight against the spring and becomes an inclined state. In this way, since the mounting base is slowly rotated to be in an inclined state, there is no risk of the mounting base hitting a person with a large impact, and safety is improved. In addition, just by pulling out the mounting base, the mounting base becomes tilted due to its own weight.
It will be very easy to operate.

When the two-wheeled vehicle is placed on the mounting base in an inclined state by variously changing the setting of the spring force, the mounting base is rotated by the weight of the bicycle and the spring is further compressed. Thus, the force of the spring can be made stronger and stronger. Therefore, when lifting the mounting base on which the two-wheeled vehicle is mounted, the operation of lifting the mounting base becomes very light due to the assisting force of the energy storage assist device, and even a weak person can use the hand of another person. You can operate the storage of the motorcycle by yourself without renting.

Since the power storage assisting device is housed in the guide cart, it can be made smaller than the conventional device shown in FIG. In particular, when a double-structured spring is used, the size can be further reduced. Therefore, the three-dimensional parking device for a motorcycle can secure a large parking space as compared with a device provided with a conventional power storage auxiliary device. In addition, since the power storage auxiliary device is incorporated in the guide carriage, there is an advantage that it is safe without providing a cover for covering the spring.
