Description

  The present invention relates to a bicycle parking apparatus that accommodates, for example, a bicycle vertically.

Bicycle bicycle parking lots are often provided in the vicinity of stations, commercial facilities, or housing complexes, where population density is relatively high, and securing the location is a problem.
For this reason, many types of bicycle parking devices have been proposed so that as many bicycles as possible can be accommodated in a limited space. As an example, bicycle parking devices or facilities for parking bicycles in a vertical position are proposed. Many proposals have been made.
For example, in the bicycle parking apparatus described in Patent Document 1, the front wheel of a bicycle is fixed with a wheel fixing tool, and the wheel fixing tool is directly or indirectly connected to a chain that is stretched up and down. By driving, the bicycle is lifted vertically to be accommodated.

  Similarly to this, as a method of pulling up the front wheel of a bicycle, for example, in Patent Document 2, a hoist is provided on a horizontal arm horizontally provided at the upper end of an upright vertical frame, and a rope with a hook on one end is attached to the front wheel. A two-wheeled vehicle parking facility that is hung up and pulled up is also described in Patent Document 3, in which a carrier that holds the front wheel of a bicycle is lifted by a rope stretched on a roller provided at the upper end of a support column. The device is described

  In addition to the method of pulling up these bicycles in a vertical position, as a push-up method, a person pushes the bicycle up along the rail rack and stands in this state by hanging a hanger on the upper wheel. A wheel device is also known (see Patent Document 4).

In addition to the above-mentioned method, there is also known one that uses a turning arm to lock the turning arm to the front wheel of the bicycle and turn the turning arm to accommodate the bicycle in a vertical position ( (See Patent Documents 5 and 6).
That is, in Patent Document 5, a turning arm connected to a suspension arm that fits a front wheel of a bicycle is provided. An upright-type bicycle parking apparatus is described in which the swivel arm is vertically erected by rotating the swivel arm.
In this upright type bicycle parking device, when the swing arm is turned upright, the swing arm is flipped up and biased by the tension coil spring so that the swing arm is turned upright and the bicycle is set up vertically. Thus, the upright swivel arm is engaged with the locking pin and the hook plate to restrain the bicycle in the upright position where the bicycle is suspended.

Further, Patent Document 6 includes a bicycle parking facility provided with a hook for hooking a front wheel of a bicycle at a free end, and a turning arm biased in a direction of turning upward by a tension spring via a chain and a slider. Is described.
In this bicycle parking facility, when the swivel arm is lowered, the movement is restricted by a pawl and a pawl so that the arm is swung only in the downward direction, and when the swivel arm is swung upward, the arm is not lowered. When the bicycle is lifted, the former pawl and the pawl wheel are disengaged and a pulling force is used to turn to a vertical position.

  As described above, various types of parking devices have been developed for parking bicycles in a vertical position. However, what has been developed so far, for example, in the type of lifting a bicycle described in Patent Documents 1 to 3, requires a chain or rope drive device, so the device structure is complicated and costly. In addition, the device itself is increased in size. Further, the device described in Patent Document 4 that is pushed up by a person has a relatively simple structure and a small number of parts, but it is not easy to operate by a weak person.

Furthermore, the upright type bicycle parking device described in Patent Document 5 not only uses a suspension arm with a special structure for mounting the front wheel of the bicycle, but also restrains the bicycle in an upright position where the bicycle is suspended. Requires a holding means. Further, in the paragraph “0018”, “as soon as the swivel arm 4 is turned upright, the horizontal pivot 3 crosses the straight line connecting the spring receiving portion 28 and the spring receiving portion 29 to the front side, and at the moment the tension coil spring 30 is attached. The direction of the force is reversed, and the swing arm 4 is flipped up and biased in the standing direction, so that the swing arm 4 is easily turned upright. " A force for reversing the biasing direction of the tension coil spring is required when turning the. For this reason, this is not easy for a powerless person.
In addition, the bicycle parking facility described in Patent Document 6 uses a chain transmission mechanism for turning the turning arm, and two pairs of pawls and pawl wheels for restricting the movement of the turning arm. Therefore, the structure is complicated and the apparatus is increased in size, the number of parts is increased, and there is room for improvement in terms of cost.

  The present invention has been made in view of the problems in the conventional bicycle parking apparatus, and an object of the present invention is to provide a relatively large force in a bicycle parking apparatus that stores a bicycle vertically using a swing arm. Therefore, it is possible to operate easily and safely, and to reduce the manufacturing cost by using a simple structure.

  The present invention relates to a bicycle parking apparatus that accommodates a bicycle in a vertically standing state, and is connected to the swing arm that pulls the front wheel of the bicycle upward, and increases as the swing arm turns downward. And an urging means for applying an urging force that decreases with the turning up to the turning arm, a lock for restricting the turning up of the turning arm, a lock operating means for operating the lock, and a lock for releasing the lock. Release means, and the lock actuating means actuates the lock in cooperation with the lowering operation of the swivel arm.

  According to the present invention, a bicycle parking device that vertically accommodates a bicycle using a swing arm can be operated easily and safely with relatively little force, and has a simple structure. Can be reduced.

Hereinafter, a bicycle parking apparatus according to an embodiment of the present invention will be described with reference to the drawings.
(First embodiment)
FIG. 1A is a front view showing an entire bicycle parking apparatus according to the present embodiment for vertically accommodating a bicycle, and FIG. 1B is an enlarged view of the hook of FIG. 1A and its attachment to a turning arm. It is a figure which shows a state. 2 and 3 are enlarged perspective views showing the lock mechanism.
The bicycle parking apparatus 1 generally includes a bicycle accommodation mechanism 2 including a turning arm 10 (1) and a lock mechanism 3 for locking the turning arm 10 (1) in a lowered position. Yes. Here, the bicycle housing mechanism 2 will be described first.

The accommodation mechanism 2 includes a swing arm 10 (1) and an operating mechanism that operates the swing arm 10 (1) between a lowered position and a raised position by applying a biasing force to the swing arm 10 (1).
The revolving arm 10 (1) is a rod-shaped member, one end of which is connected to a revolving plate 12, which will be described later, and a hook 10a that is hooked to the front wheel of the bicycle is provided at its free end. Here, although the swivel arm 10 (1) and the swivel plate 12 are separate bodies, they may be integrally formed. Therefore, unless specifically discussed, the swivel arm 10 includes the swivel plate 12 for convenience. (1).

In FIG. 1A, the swivel arm 10 (1) is swung upward, and this state is a stowed state in which the swivel arm 10 (1) is stowed vertically by being hooked by a hook 10a that is a support means for supporting the front wheel of the bicycle. The shape of the hook 10a is arbitrary. For example, the hook 10a is attached at a right angle to the swivel arm 10 (1) as shown in FIG. 1B (1), which is an enlarged view of the hook 10a in FIG. 1A. The outer end is an oval flange portion 10a (1) that is prevented from coming off, the opposite end is a large diameter portion 10a (2) that is an attachment portion to the turning arm 10 (1), and the large diameter portion 10a (2 ) And the flange portion 10a (1), and a cylindrical locking portion 10a (3) with a central portion is provided.
When attaching the hook 10a to the swivel arm 10 (1), the swivel arm 10 (1) is swung down and attached so that its long diameter is substantially perpendicular to the floor surface (FIG. 1B (2)). ) Since the hook 10a has a vertically long shape with respect to the floor surface, the hook 10a can be easily inserted between the spokes of the front wheel of the bicycle and can be easily hooked on the rim, rather than a hook having a circular flange. Further, when the swing arm 10 (1) is swung up and at the bicycle storage position where the swivel arm 10 (1) is swung up (FIG. 1B (3)), the center of the hook 10a is constricted. The bicycle can be supported in a stable state in which the curved surfaces of the stop portion 10a (3) and the rim of the bicycle front wheel become familiar.

1C shows another hook 10b, FIG. 1C (1) is a side view thereof, FIG. 1C (2) is a side view of a hook mounting screw, and FIG. 1C (3) is a front view thereof.
The hook 10b has a groove-like cross section (substantially U-shaped) composed of a side wall 10b (1), 10b (2) and a bottom wall 10b (3) connecting the side walls 10b (1), 10b (2). For example, a plate-like member made of metal or synthetic resin. Specifically, of the side walls 10b (1) and 10b (2), the side wall (right side wall in the figure) 10b (2) on the bicycle front wheel side is the opposite side of the turning arm 10 ( 1) The side wall (the left side wall in the figure) 10b (1) which is the mounting side is formed to be lower than the side wall 10b (1). An inclined surface inclined so that the groove becomes deeper toward the left side, that is, downward from the side wall 10b (2) on the front wheel insertion side toward the side wall 10b (1) on the mounting side to the turning arm 10 (1). It is configured. This is because when the hook 10b is inserted between the front wheel spokes of the bicycle and the bicycle is lifted, the bicycle can slide to the left side of the figure along the inclined surface by its own weight, and the bicycle is detached from the hook 10b during the suspension. It is for preventing. Further, the contact surface of the bottom wall 10b (3) with the front wheel rim is formed in an arc shape corresponding to the shape of the front wheel (not necessarily coincident) so as to be familiar with the front wheel of the bicycle.

The hook 10b can pivot with respect to the pivot arm 10 (1) so that the bottom wall 10b (3) can always receive and support the rim of the front wheel regardless of the pivot position of the pivot arm 10 (1). Is attached. The hook 10b can be attached to the swivel arm 10 (1) as desired, but here, the hook 10b is attached by an attachment screw 10b (4) shown in FIG. 1C (2). That is, a nut (not shown) is attached to a screw hole (not shown) provided in the turning arm 10 (1) or attached to an end of a screw inserted into the hole, and the hook 10b is attached to the turning arm 10 (1). ) Around the axis of the screw.
As shown in FIG. 1C (3), the hook 10b has a curved bottom wall 10b (3) so as to conform to the curved shape of the bicycle rim.

By the way, as shown in the figure, the hook 10a has a cylindrical shape with a narrowed center and has a simple structure and is easy to manufacture. In addition, it is easy to insert into the front wheel and is easy to use. However, as shown in FIG. 1B (2), when attached to the swing arm 10 (1), the locking portion 10a (3) protrudes laterally from the side surface of the swing arm 10 (1). For this reason, when the hook 10a is inserted into the front wheel of the bicycle, if the insertion position is accidentally near the generator, the swing arm 10 (1) and the generator may interfere with each other and may be difficult to insert.
The hook 10b is an improvement of this point. The hook 10b has a U-shaped cross section, and the swivel arm 10 (1) is swung down as shown in FIG. 8 to lock the rim of the front wheel of the bicycle to the hook 10b. At this time, the bottom wall 10b (3) serving as the locking portion is attached to the swing arm 10 (1) so as to be lower than the swing arm 10 (1). That is, the relative position of the bicycle with respect to the swing arm 10 (1) when locked to the hook 10b is shifted downward as compared with the case of the hook 10a, whereby the swing arm 10 (1) and the bicycle generator interfere with each other. I try not to.

The swivel plate 12 has a projecting portion 12a that is pivotally connected to a vertically standing vertical frame 16 by a pivot shaft 16b and that projects in a triangular shape from a portion connecting the distal end and the base end. An upper end portion of the first link arm 13 is rotatably connected to the apex portion of the projecting portion 12a, and a lower end thereof is pivotally attached to a base end portion of the vertical frame 16 by a rotating shaft 15a. A gas spring 15 which is the biasing means is rotatably connected.
The gas spring 15 has a structure that imparts an upward turning force to the turning plate 12 using, for example, an elastic force generated by oil partitioned by a piston and high-pressure gas.

A second end of the first link arm 13 is pivotally attached to the vertical frame 16 with a pivot shaft 14b between a pivot portion of the first link arm 13 with the projection 12a and an upper end of the gas spring 15. The other end of the link arm 14 is rotatably connected.
As shown in FIGS. 2A and 3, the second link arm 14 includes a pair of rectangular elongated link arm pieces 14 (1). Both ends of the lock pin 14a which is a lock body are connected. The lock pin 14a is for locking the turning arm 10 (1) in cooperation with a lock plate 23 which is a lock body in the lock mechanism 3 described later.

  Here, the revolving arm 10 (1), the first and second link arms 13, 14 and the gas spring 15 constitute a link mechanism for revolving the revolving arm 10 (1). The urging force increases as the turning arm 10 (1) descends, and the urging force decreases as the turning arm 10 (1) rises. The biasing force of the gas spring 15 is adjusted to a size that allows the bicycle to be held in a vertically standing state at the top dead center position of the link mechanism.

Since the urging force of the gas spring 15 increases as the swing arm 10 (1) descends, the swing arm 10 (1) is lowered and the front wheel of the bicycle is hooked on the hook 10a of the swing arm 10 (1). At this time, it can be lifted lightly by the urging force of the gas spring 15.
On the other hand, since a relatively large urging force acts on the swivel arm 10 (1) lowered, it is necessary to stably hold the swivel arm 10 (1) at the lowered position. Therefore, in this embodiment, the lock mechanism 3 that restricts the upward movement of the swing arm is provided.

Next, the lock mechanism 3 will be described.
2A and 3 are enlarged perspective views of the second link arm 14 and the lock mechanism 3 in the unlocked state and the locked state, respectively. Here, the lock mechanism 3 further includes a lock portion, a lock operation portion, and a lock release portion.

The lock part is a lock body that is provided with a lock pin engaging part 23a composed of a notch for engaging the lock pin 14a on one end side, and a leg part 23b on the other end side, and is configured in a substantially letter-like shape as a whole. A lock plate 23, a rectangular connection plate 24 integrally connected to the lower end portion of the leg portion 23b of the lock plate 23, and a lower rotation portion of the leg portion 23b are connected to the connection plate 24 in a relatively rotatable manner. The cam follower 25, the rod 27 integrally connected to the lower end of the cam follower 25 shown in the figure, the spring receiving metal fitting 26 provided with the insertion hole 26a through which the lower end of the rod 27 is inserted, and the lower surface of the cam follower 25 And a coil spring 28 disposed so as to surround the rod between the spring receiving brackets 26.
The shape of the cam follower 25 is arbitrary, but in this embodiment, the cam follower 25 has a rectangular shape with a tapered cam follower surface corresponding to a lock cam 22 constituting a lock release portion described later on one upper side surface thereof. Is formed.

  Here, as shown in an enlarged view in FIG. 2B, the lock pin engaging portion 23a of the lock plate 23 receives and guides the lock pin 14a that descends as the swivel arm 10 (1) pivots downward. (1) and the guide part 23a (1), it is comprised by the notch used as the accommodating part 23a (2) of the lock pin 14a cut into the vertical frame 16 side upwards and the horizontal direction from there.

  As shown in FIG. 2A or FIG. 5 to FIG. 7 described later, the lock actuating portion is a T-shape in a plan view comprising a main plate 30a extending left and right and an intermediate portion of the main plate 30a extending at a right angle to the main plate 30a. A mold plate (referred to as a T-shaped plate) 30 and an abutment fitting 31 that is integrally formed at a tip of the main plate 30a at a predetermined angle with respect to the longitudinal direction of the main plate 30a or is swingably connected. The rod 36 (1) rotatably attached to the lower end of the main plate 30a, that is, the end opposite to the attachment end of the contact metal fitting 31, and the lower end of the rod 36 (1) were inserted. The rod receiving portion 35, the coil spring 36 (2) fitted around the rod 36 (1) between the rod receiving portion 35 and the T-shaped plate 30, and the intermediate plate 30b of the T-shaped plate 30 at one end. Times Is rotatably connected to the mounting flange 21a provided on the outer peripheral surface of the lock lever shaft 21 the other end will be described later (FIG. 4B), a drive plate 33 which is mounted rotatably, consist. The surface of the contact fitting 31 is preferably formed as a surface inclined as shown in the figure with respect to the surface of the T-shaped plate 30 in order to perform the locking operation.

  As shown in FIGS. 2A, 4A, and 4B, the unlocking portion includes a lock lever 20 and a lock lever shaft 21 that is connected to one end of the lock lever 20 at right angles to the lock lever 20, and a periphery of the lock lever shaft 21. It consists of a lock cam 22 facing the surface.

Next, the operation of the lock mechanism 3 will be described first.
As described above, the bicycle parking apparatus 1 according to the present embodiment is in a locked state that restricts the upward movement of the swing arm 10 (1) in order to mount the bicycle. Therefore, the swivel arm 10 (1) cannot be raised unless the locked state is released. Therefore, the lock is released after the bicycle is mounted, and then the turning arm 10 (1) is raised. The raised end position of the swing arm 10 (1) is a position where the bicycle is stood vertically and accommodated, but in this state, the lock remains released.
The re-locking of the released lock is automatically performed using the swivel lowering operation when the swivel arm 10 (1) is swung down. This returns to the initial locked state.
In the present embodiment, the locking and unlocking operations are repeated as the bicycle is taken in and out of the bicycle parking device.

Next, the operation of the unlocking portion of the lock mechanism 3 will be specifically described with reference to the drawings.
First, the swing arm 10 (1) will be described from the lowered position, that is, the standby state where the bicycle parking apparatus waits for the bicycle to be accommodated (the lock mechanism 3 is in the locked state).
3 and 4A show a state where the lock mechanism 3 is activated when the swing arm 10 (1) is in the lowered position. In this state, the second link arm 14 is in the lowered position, and the lock pin 14 a is located in the lock pin engaging portion 23 a of the lock plate 23.
Further, the lock lever 20 is in a downward position rotated clockwise by 45 ° to 90 °, preferably 45 ° from the time of unlocking, and the cam follower 25 is disengaged from the lock cam 22 of the lock lever shaft 21, and the coil Under the urging force of the spring 28, the connecting plate 24 and the rotating shaft 25a are rotated relative to each other so as to abut on the peripheral surface of the lock lever shaft 21. Further, the rotation shaft 25a of the cam follower 25 is also in a position slightly rotated counterclockwise around the spring bracket 26 than when the lock is released.

On the other hand, the connecting plate 24 connected by the rotating shaft 25a and the leg portion 23b of the lock plate 23 connected integrally to the connecting plate 24 are more clockwise than when the lock is released around the rotating shaft 23c of the lock plate 23. In a slightly rotated position.
When the swing arm 10 (1) is lifted in this state, the lock pin 14a in the lock pin engaging portion 23a ascends the accommodating portion 23a (2) (FIG. 2B) of the lock pin engaging portion 23a of the lock plate 23. And abuts on the top. Therefore, the swivel arm 10 (1) cannot be lifted any further.

  Next, in order to release the lock, as shown in FIGS. 2A and 4B, when the lock lever 20 is rotated counterclockwise, for example, 45 °, the lock lever shaft 21 integrally connected to the lock lever 20 is also counterclockwise. Turn 45 °. When the lock lever shaft 21 rotates, the lock cam 22 provided on the peripheral surface of the lock lever shaft 21 contacts the cam follower 25, and the cam follower 25 rotates clockwise with respect to the connecting plate 24 around the rotation shaft 25a. At the same time, and at the same time, slightly pivots clockwise around the spring bracket 26. This rotation is transmitted to a connecting plate 24 that is rotatably connected to the rotation shaft 25a. The connecting plate 24 rotates slightly counterclockwise around the rotating shaft 23c of the lock plate 23 together with the leg portion 23b of the lock plate 23 connected integrally therewith.

When the lock plate 23 is slightly rotated counterclockwise around the rotation shaft 23c, the relative position between the lock pin engagement portion 23a and the lock pin 14a disposed in the lock pin engagement portion 23a changes. To do. That is, the position of the accommodating portion 23a (2) of the lock pin 14a that has prevented the lock pin 14a from rising is shifted counterclockwise with respect to the lock pin 14a, and the guide portion 23a (1) is moved to that position. come. As a result, when the turning arm 10 (1) is raised, the lock pin 14a can be raised through the guide portion 23a (1). That is, the turning arm 10 (1) can be turned upward.
A series of mechanisms that transmit the rotation to the lock plate 23 by the rotation of the lock lever shaft 21 by the rotation of the lock lever 20 are collectively referred to herein as interlocking means.

Next, the operation of the lock operation unit of the lock mechanism 3 will be described.
As already described, in a state where the swing arm 10 (1) is turned to the top dead center position and stopped, the unlocked state is maintained.
Here, when the turning arm 10 (1) is turned downward, the second link arm 14 is turned from the state shown in FIG. 2A to the state shown in FIG.

5, 6, and 7 are perspective views of the second link arm 14 and the lock operation unit when the revolving arm 10 (1) revolves from the upper end to the lower end position, as viewed from the back side of the lock operation unit illustrated in FIGS. 2A and 3. FIG.
That is, from the unlocked state shown in FIG. 5, the second link arm 14 starts to turn downward around the rotating shaft 14b and lowers as the turning arm 10 (1) turns downward. The lower end of the link arm piece 14 (1) on the right side of the second link arm 14 in the drawing contacts the contact fitting 31 of the lock operating portion.

  When the swivel arm 10 (1) is swung further downward, that is, clockwise in FIG. 1A from this state, the second link arm 14 has the lower end of the outer (right) link arm piece 14 (1) at the abutment fitting 31. As shown in FIG. 6, the second link arm 14 is moved downward while pushing and opening the abutment metal 31 outwardly with the abutment upper end surface of the abutment metal 31 as a guide. It passes through the contact fitting 31 and stops at the position shown in FIG. By this operation, the lock pin 14a of the second link arm 14 is guided by the guide portion 23a (1) of the lock pin engaging portion 23a of the lock plate 23 and accommodated therein.

  On the other hand, in the process in which the contact fitting 31 is pushed by the link arm piece 14 (1), as shown in FIG. 6, the T-shaped plate 30 that is integrally or rotatably connected to the contact fitting 31. The intermediate plate 30b is rotated in the counterclockwise direction (arrow A direction) around a rotation shaft 30c appropriately supported by the vertical frame 16. When the intermediate plate 30b is rotated in the counterclockwise direction, the lock arm 33 connected to the rear end thereof is also rotated in the same direction, and the lock arm 33 is rotated to the other end via the mounting flange 21a (FIG. 4B). Then, the lock lever shaft 21 and the lock lever shaft 20 integrally connected thereto are rotated 90 ° counterclockwise.

  Note that the lock plate 23 rotates slightly clockwise around the rotation shaft 23c in FIG. 2 contrary to the case where the lock described above is released by the rotation of the lock lever shaft 21. Due to the slight rotation of the lock plate 23 in the clockwise direction, the lock pin engaging portion 23a of the lock plate 23 is slightly rotated in the clockwise direction above the inserted lock pin 14a to reach the lock position. The pin 14a is prevented from coming off.

The operation of the lock mechanism 3 has been described above. Next, the operation of the entire bicycle parking device 1 according to this embodiment will be described.
FIG. 8 is a front view showing a state where the bicycle is to be accommodated using the bicycle parking apparatus 1, and the hook 10a of the turning arm 10 (1) of the bicycle parking apparatus 1 is locked to the front wheel of the bicycle. FIG.
In this state, the lock arm 33 faces downward, indicating that the lock mechanism 3 is in the locked state. Here, when the lock arm 33 is turned counterclockwise to release the lock, the urging force of the gas spring 15 is applied to the turning arm 10 (1) in the direction of pulling up the front wheel of the bicycle as described above. Therefore, a person who intends to park a bicycle only supports the bicycle lightly and pushes the rear wheel lightly according to the posture of the bicycle, so that the bicycle is pulled up smoothly and stands upright.
Therefore, it does not require so much lifting force, and even a weak person can easily park the bicycle in a stowed state in which the bicycle is stood vertically.

FIG. 9 is a front view showing a state where the bicycle is stood vertically and accommodated using the bicycle parking apparatus 1.
In the present embodiment, the bicycle housed vertically is not particularly required to have a locking tool or the like, and the top dead center of the link mechanism including the turning arm 10 (1) in a state where the front wheel is suspended by the hook 10a. The stowed and stowed state is maintained stably at the position.

When the bicycle is lowered from the bicycle parking apparatus 1 onto the floor or the ground, for example, the vertically raised bicycle is pulled down obliquely downward. This operation resists the urging force of the gas spring 15 that gradually increases as it is pulled down. However, because the weight of the bicycle is acting, even a weak person can pull it down relatively easily.
As the bicycle is pulled down, the swivel arm 10 (1) turns in the clockwise direction, and as described above, the lock operation is automatically performed in the process of lowering the turn, and in the state where the bicycle is lowered to the horizontal floor surface. The swivel arm 10 (1) is automatically locked and waits for the next parking.

(Second Embodiment)
Next, a second embodiment of the present invention will be described.

Each of the frame members 52 is inserted into the inside thereof from the hollow end of the second swivel arm 10 (2) b as shown in the figure. For example, a pair of bolts 53 are attached to both sides of the frame member 52 as shown in the figure. Are inserted into the second swivel arm 10 (2) b at one end, and are inserted into the second turning arm 10 (2) b. In addition, an arcuate guide edge 52d that is an engaged member guide portion that guides a locking pin 54 that is an engaged member, and a guide edge 52d that guides a locking pin 54 that is an engaged member are provided on the upper portion of the frame body following the insertion portion 52c of the frame member 52. First and second convex portions 52a and 52b that serve as stoppers for the locking pins 54 are formed at both ends of the first and second projections. The guide edge 52d can guide the locking pin 54 of the first turning arm 10 (2) a continuously while the second turning arm 10 (2) b is turning. ) A and the second turning arm 10 (2) b are formed so as to form an arc centered on the rotation center.

A hole is provided in the center part of the pair of frame members 52, and a cylinder 58 is attached to the hole, and inside the cylinder 58, an inside attached to one end of the first turning arm 10 (2) a. A cylinder 55 having a thread groove to be screwed with the bolt 59 is fitted so as to be rotatable. Next, a bolt 59 is screwed into the cylinder 55 via a washer 59a, so that the first turning arm 10 (2) a and the second turning arm 10 (2) b are rotatably connected.
The first and second convex portions 52a and 52b of the pair of frame members 52 are connected and fixed at predetermined intervals with stoppers such as screws 57a and 57b. Within the fixed interval, a leaf spring 56 mounted between the screws 57a and 57b of the first and second convex portions 52a and 52b is disposed. The both ends of the leaf spring 56 are wound around the barrel portions of cylindrical barrel screws 57a and 57b, respectively, and are fixed by caulking, for example.

  As shown in FIG. 11A, the leaf spring 56 includes concave surface portions 56a and 56b and an intermediate portion 56c that connects the concave surface portions 56a and 56b in the vicinity of the end portions thereof. Here, the intermediate portion 56c is formed in a flat shape as shown in the figure, but the shape thereof is such that when the second turning arm 10 (2) b is turned, the locking pin 54 has an arc shape. As long as it does not prevent the relative movement while being guided by the guide edge 52d, it is optional.

  Here, since the locking guide mechanism 51 is integrally connected to the second turning arm 10 (2) b, when the second turning arm 10 (2) b is turned in either the folding or unfolding direction. The locking pin 54 provided on the first turning arm 10 (2) a is guided by the arcuate guide edge 52d of the frame member 52 and relatively moves. When the locking pin 54 is disengaged from the guide edge 52d and engages with the locking portion constituted by the concave surface portion 56a or 56b and the first or second convex portion 52a or 52b, the relative movement of the locking pin 54 is further increased.

FIG. 12 is a perspective view for explaining the operation of the first and second swing arms 10 (2) a, 10 (2) b described above.
FIG. 12A shows a state where the first and second swivel arms 10 (2) a, 10 (2) b are deployed in a straight line. That is, the locking pin 54 of the first swing arm 10 (2) a is connected to the concave surface portion 56a of the leaf spring 56 of the locking guide mechanism 51 attached to the second swing arm 10 (2) b and the first of the frame member 52. The second swivel arm 10 (2) b is shown in the figure and is turned clockwise by the leaf spring 56, and the counterclockwise turn is the second turn arm 10 (2) b. Each of the protrusions 52a is in a locked state that is blocked. This state corresponds to a state immediately before the bicycle is suspended (FIG. 8) or immediately after it is lowered.

  12B and 12C, in the state of FIG. 12A, the user removes the front wheel of the bicycle from the hook 10b and lifts the second turning arm 10 (2) b against the elastic force of the leaf spring 56, and the leaf spring 56 shows a state in which the locking pin 54 of the first swing arm 10 (2) a is brought into contact with the guide edge 52d of the frame member 52 by deforming 56. In this state, the locking pin 54 moves away from the leaf spring 56 and is guided by the arc-shaped guide edge 52d of the frame member 52, and smoothly moves relative to the state of FIG. 12C from the state of FIG. 12B. The user can lift the second turning arm 10 (2) b lightly.

In this state, the locking pin 54 of the first swing arm 10 (2) a is formed by the concave surface portion 56b of the leaf spring 56 of the second swing arm 10 (2) b and the second convex portion 52b of the frame member 52. The second swivel arm 10 (2) b is shown in the drawing, counterclockwise turning is performed by the leaf spring 56, and clockwise turning is performed by the second convex portion 52b. It is in a blocked lock state.
In the above description, the locking guide mechanism 51 is described as being attached to the second turning arm 10 (2) b, and the locking pin 54 is attached to the first turning arm 10 (2) a. The relationship may be reversed. That is, the locking guide mechanism 51 may be attached to the first turning arm 10 (2) a, and the locking pin 54 may be attached to the second turning arm 10 (2) b.

As mentioned above, although embodiment of this invention was described, according to this embodiment, a comparatively simple link mechanism which combined the gas spring 15 and turning arm 10 (1), 10 (2) requires much force. The bicycle can be smoothly moved from the horizontal position to the vertical position or vice versa.
Further, since the swing arms 10 (1) and 10 (2) are kept in the lowered position by being locked, the person using the bicycle parking apparatus 1 can rotate the swing arms 10 (1) and 10 (2) that have lowered the front wheels of the bicycle. ) Can be easily hooked on the hook 10a attached to the tip of the bracket.
Thereafter, by operating the lock lever 20 to release the lock, even a weak person who is assisted by the urging force of the gas spring 15 can easily move the bicycle to the vertical position.

A vertically erected bicycle can maintain its state by utilizing the dead point of the link mechanism including the swing arms 10 (1) and 10 (2) and the gas spring 15. Therefore, the holding means like the conventional bicycle parking apparatus of the same kind is unnecessary.
In addition, when lowering a vertically erected bicycle to the floor or the ground, it is only necessary to pull the bicycle obliquely, and since it is automatically locked in the process, it is easy to operate without inconvenience such as locking. . In addition, there is no risk of the swivel arm jumping up as soon as it is forgotten to lock and as soon as it is lowered onto the floor and the hook is removed.
Furthermore, since the number of parts is smaller than that of a conventional device of the same type, the structure is relatively simple, and the size is small, there is an advantage that it is difficult to break down and does not require a place. There is an advantage that the cost can be reduced.

In addition, according to the second embodiment, the swing arm 10 (2) can be further folded and folded, so that the bicycle parking device when not in use can be made compact, and does not get in the way in a narrow place. Rather, the vacant space can be used effectively.
Further, the means for locking the first and second swivel arms in the folded state is composed of a combination of a leaf spring, a locking pin, and a convex portion serving as a stopper. In addition, by selecting leaf springs having different elastic forces, the force required to engage and disengage the locking guide mechanism can be easily adjusted.

Next, modifications of some members in the embodiments described above will be described.
First, the modification of the connecting plate 24 described in relation to FIG. 2A will be described.
FIG. 13 is an enlarged perspective view of the second link arm and the lock mechanism in the unlocked state similar to FIG. 2A.
Here, in the second link arm and the lock mechanism shown in FIG. 13, only the parts different in configuration will be described, and the same parts as those shown in FIG.
First, the connecting plate 24A shown in FIG. 13 is a groove member having a U-shaped cross section with a flat bottom surface as shown in the figure, and a cam follower 25 can be rotated by a rotation shaft 25A in the groove. It is accommodated in the state connected with.
Therefore, in this configuration, in order to release the lock, when the lock lever 20 is rotated counterclockwise, for example, 45 ° in FIG. 13, the lock lever shaft 21 connected integrally with the lock lever 20 is also anticlockwise. Turn 45 °. When the lock lever shaft 21 rotates counterclockwise, the lock cam 22 provided on the peripheral surface of the lock lever shaft 21 abuts on the back surface of the groove bottom of the connection plate 24A, and the connection plate 24A and the lock plate integrally connected thereto. The leg portions 23b of the lock plate 23 are slightly rotated counterclockwise around the rotation shaft 23c of the lock plate 23. At the same time, the cam follower 25 connected to the connecting plate 24A by the rotating shaft 25A is rotated clockwise around the spring receiving bracket 26 together with the rod 27 integrally connected thereto. The subsequent operation is as described above.
The rod 27 shown in FIG. 13 is provided with another spring support 26A on the top of the rod 27 in addition to the spring support 26 below the rod 27. By arbitrarily setting the attachment position of the spring receiving bracket 26A on the rod 27, it is possible to correspond to the lengths of the coil springs 28 having different lengths. Therefore, for example, the coil spring 28 can be shared with the coil spring 36 (2) fitted around the rod 36 (1) between the plate-shaped rod receiving portion 35A and the T-shaped plate 30A. .

Next, a modification of the plate 30 described in relation to FIG. 2A will be described with reference to FIG.
The contact fitting 31 of the plate 30 shown in FIG. 2A is rectangular, but this shape is an inverted triangle or fan-shaped contact fitting 31A that expands toward the tip as shown in FIG. It may be configured.
Further, the rotation shaft 30c of the main plate 30a of the plate (T-shaped plate) 30 shown in FIG. 2A is rotated by the rotation shaft 30c between the bifurcated leg portions 62 of the support fitting 60 fixed to the vertical frame 16. It may be configured to be connected and supported.
FIG. 14 is a perspective view of the support fitting 60, which is the same view as FIG.

3 is located outside the pair of rectangular elongated link arm pieces 14 (1) in the locked state, the present invention is not necessarily limited thereto.
That is, FIG. 15 is an enlarged perspective view of the second link arm and the locking mechanism in the locked state similar to FIG. 3, but as shown here, the plate 30A has a pair of rectangular elongated links in the locked state. You may make it be inside the arm piece 14 (1).
In this case, in FIG. 15, when the pair of link arm pieces 14 (1) of the second link arm 14 turn downward around the turning shaft 14b, the outer (right side) link arm piece 14 thereof. The lower end of (1) comes into contact with the right end of the contact fitting 31A, and the contact upper end surface of the contact fitting 31A serves as a guide to push the contact fitting 31A inwardly and descend while pushing down. The arm 14 passes through the contact fitting 31A and stops. By this operation, the lock pin 14a of the second link arm 14 is guided by the guide portion 23a (1) (FIG. 2B) of the lock pin engaging portion 23a of the lock plate 23 and accommodated therein. This is the same as the case of the plate 30 shown in FIG.

Next, a modification of the locking guide mechanism described with reference to FIG. 11 will be described.
16 is a modified example of the locking guide mechanism of FIG. 11, FIG. 16A is a front view thereof, and FIG. 16B is a plan view thereof.
In the locking guide mechanism shown in FIG. 16A, instead of the leaf spring 56c provided in the locking guide mechanism 51 shown in FIG. 11, the first turning arm 10 (2) a and the second turning arm 10 (2). The rotation connecting portion b is provided with resistance force adding means for adding a rotation resistance force. This will be described below. Since the portions other than those described below are the same as those shown in FIG. 11, the same reference numerals are given and description thereof is omitted.
That is, in the locking guide mechanism 51 shown in FIG. 11, when the first and second turning arms 10 (2) a, 10 (2) b are locked, the leaf spring 56 maintains the locked state. Therefore, when the lock is released, the locking pin 54 is deformed and moved relative to the elastic force of the leaf spring 56, so that the lock is not released unnaturally.
Therefore, in the locking guide mechanism 51A of FIG. 16A, in order to maintain the locked state of the first and second swivel arms 10 (2) a, 10 (2) b, the rotation around the first swivel arm 10 (2) a Thus, when the second swivel arm 10 (2) b is swung (rotated), a configuration is adopted in which a resistance force is applied to the swivel.

Specifically, as shown in FIG. 16B, the tip of the first swivel arm 10 (2) a (the center of FIG. 14B) is placed in the cylinder 58 of the first swivel arm 10 (2) a. The cylinder 55 attached to one end of the first swivel arm 10 (2) a is rotatably fitted, and the bolt 59 is screwed to the first swivel arm 10 (2) a and the second swivel arm 10 ( 2) When b is rotatably connected, a disc spring 65 (1) and a resin washer (washer) 65 (2) are provided between the first swing arm 10 (2) a and the side surfaces of the pair of frame members 52. Is interposed, and a spring washer 65 (3) and a flat washer 65 (4) are interposed between the side surface of the other frame member 52 and the head of the bolt 59, and the bolt 59 is screwed together.
Accordingly, the frame member 52 attached integrally to the first swing arm 10 (2) a and the second swing arm 10 (2) b is brought into close contact with the first swing arm 10 (2) b via the disc spring 65 (1) by the tightening force of the bolt 59, A resistance force can be applied to the turning of both of them. Therefore, by adjusting the tightening force of the bolt 59, the lock of the first turning arm 10 (2) a and the second turning arm 10 (2) b can be released and the turning resistance force during turning can be adjusted. it can.
Here, a disc spring 65 (1), a resin washer 65 (2), and a spring washer are added to the pivotal connecting portion between the first pivot arm 10 (2) a and the second pivot arm 10 (2) b in FIG. 65 (3) constitutes a resistance applying means.
The resistance applying means is not limited to this configuration, and any means can be used as long as it can apply a resistance when the first turning arm 10 (2) a and the second turning arm 10 (2) b are rotated. A structure can be used.

  A plate spring is used as compared with the locking guide mechanism shown in FIG. 11 by using resistance applying means as a lock maintaining mechanism for the first swing arm 10 (2) a and the second swing arm 10 (2) b. As in the case, since the processing of the leaf spring is not required, the structure is simple, and since only a common mechanism part is required for the additional part, there is a cost advantage. In addition, there is a merit that the lock maintaining force can be easily changed only by adjusting the tightening force of the bolt 59.
