[Detailed Description of the Invention] This invention relates to a bicycle parking lock device for mooring, for example, a bicycle.

Figure 1 shows a conventional device of this type.
1 is a support. At the top of this support 11 is a housing 1.
2 is provided, and curved scissor-shaped holding members 13, 13 are provided on the front surface of this casing 12. The holding members 13, 13 are rotatable in the direction of the arrow shown in the figure around a fulcrum located inside the housing 12, and the movement of the holding members 13, 13 is controlled by the movement of the holding members 13, 13 provided inside the housing 12. For example, this is carried out using a plunger or the like. That is, the inner ends of the housing 12 of the holding members 13, 13 are opened and closed by the plunger, and the outer ends of the housing 12 of the holding members 13, 13 are opened and closed. Therefore, the holding members 13, 13
The wheels 14 are inserted between the holding members 13 and 1.
3 and locking the inner end of the housing 12, the bicycle is moored.

In the device having the above configuration, the holding member 13,
In other words, it was difficult to make the length of the inner end of the housing 12 relative to the fulcrum of the holding members 13, 13 sufficiently longer than the length of the outer end of the housing 12, and therefore it was not possible to apply a sufficient force to the outer ends of the holding members 13, 13.
The outer ends of the holding members 13, 13 can be easily pried open with pieces of wood, etc., which is not desirable in terms of preventing theft of bicycles, etc. Furthermore, if pried open, the outer or inner ends of the holding members 13, 13 can be deformed or damaged, making it difficult to reuse the product and shortening its useful life.

This invention was made based on the above circumstances, and its purpose is to be able to hold the wheels of bicycles etc. with sufficient force, which is advantageous in terms of preventing theft, and also to prevent the product from being easily damaged. The object of the present invention is to provide a bicycle parking locking device that can extend the service life of the bicycle.

An embodiment of this invention will be described below with reference to the drawings.

In FIGS. 2 to 4, 21 is an outer frame having a concave cross section. Inside this outer frame 21, an inner frame 22 having a concave cross section is rotatably provided. That is, the opposing parts 23 and 23 of the outer frame 21 are provided with through holes 2, respectively.
4, 24 are provided, and shaft portions 26, 26 protruding from the outer surfaces of the opposing portions 25, 25 of the inner frame 22 are rotatably fitted into the through holes 24, 24. In addition, the bottom shape of the inner frame 22 is V-shaped,
The inner frame 22 can be rotated like a seesaw motion about the shaft parts 26, 26 by the wheels of a bicycle or the like that is brought in and out of the interior. Slanted portions 27, 27 are provided at one longitudinal end of the outer frame 21 and on the inner surfaces of the opposing portions 23, 23 so as to face each other. The inclined portions 27, 27 are inclined so as to be close to each other along one rotational direction of the inner frame 22 (the rotational direction accompanying the entry of the wheel).

On the other hand, one longitudinal end of the inner frame 22, and
The opposing parts 25, 25 are provided with notches, and the base ends of the rotating members 28, 28 are rotatably provided in the notches. That is, the rotating members 28, 2
The proximal ends of 8 are attached to the opposing parts 25, 25 by hinges 29, 29, respectively, and the rotating members 28, 28
is provided rotatably in the directions of arrows A and B shown in FIG. 4 within the inner range of the opposing parts 25, 25. Further, each of the hinges 29, 29 is provided with a spring (not shown), and this spring causes the rotating members 28, 28 to move away from each other (in the direction of arrow A shown in FIG. 4).
is energized by Furthermore, the rotating members 28, 28
The end surface of the outer surface of the tip portion of the
Protrusions 30, 30 whose inclination directions are opposite to each other and which come into sliding contact with the inclined parts 27, 27 are provided. Further, an abutting member 31 is provided at the other end in the longitudinal direction of the inner frame 22 and on the outer surface of the one opposing portion 25, and this abutting member 31 is provided with, for example, an engagement recess 32 that constitutes a locking member. . Further, a plunger 33, for example, constituting a locking member is provided at the other end in the longitudinal direction of the outer frame 21 and on the outer surface of the one facing portion 23, and the drive shaft 34 of this plunger 33 is rotated when power is not supplied, as shown in FIG. As shown in the figure, it penetrates through the facing portion 23 and projects. Furthermore, a reed switch 35, for example, is provided on the bottom surface of the outer frame 21 to detect the operating state of the inner frame 22 and control the operation of the plunger 33.

In addition, in FIG. 2, 36 is a guide groove provided in the outer frame 21 and guides the wheel to the inner frame 22;
Reference numeral 7 denotes a wheel stop that is provided on the outer frame 21 and restricts the entry position of the wheel.

Next, the operation of the above configuration will be explained using FIGS. 5 and 6. First, when the wheel is not inserted into the inner frame 22, the other longitudinal end of the inner frame 22 is in contact with the bottom surface of the outer frame 21, as shown by the solid line. At this time, power is not supplied to the plunger 33 by the reed switch 35, and the tip of the drive shaft 34 of the plunger 33 is brought into contact with the contact member 31. Further, the rotating members 28, 28 have protrusions 30, 30 on the inclined portions 27, 27.
Because they are located above, they are separated from each other.

In the above state, the inner frame 2
For example, a bicycle wheel enters into the inner frame 2, and when the center portion of the wheel passes through the shaft portions 26, 26, the inner frame 22 is rotated in the direction of arrow C shown in FIG. With this rotation, the protrusions 30, 30 are slid on the inclined parts 27, 27, and the rotating members 28, 28 are rotated. When one longitudinal end of the inner frame 22 is in contact with the bottom of the outer frame 21 as shown by the dotted line, the rotating members 28, 28 are at the closest position as shown in FIG. The mutual spacing between the members 28, 28 is set narrower than the width of the wheel 41 at the inner edge of the wheel 41. Further, at this time, the engagement recess 32 of the contact member 31 is in a position facing the drive shaft 34 of the plunger 33, and the drive shaft 34 is fitted into the engagement recess 32. Therefore, the inner frame 22 is in a locked state,
Furthermore, since the rotating members 28, 28 restrict the movement of the wheels 41, it becomes impossible to take out the bicycle.

On the other hand, when removing the bicycle from the above condition,
For example, the plunger 3 is activated by a well-known key switch (not shown) or a switch operated by inserting a coin.
Supply power to 3. Then, the plunger 33 is operated and the drive shaft 34 is pulled out from the engagement recess 32. In this state, when the bicycle is pulled toward the other longitudinal end of the outer frame 21, the inner frame 22 is rotated in the direction of arrow D shown in FIG. As the inner frame 22 rotates, the rotating members 28, 28 are rotated by springs in the hinges 29, 29 in a direction away from each other. Thus, when the inner frame 22 is returned to the position shown by the solid line, the holding state of the wheel 41 is released and the bicycle can be taken out. In this state, the inner frame 22 is also
is detected, the power supply to the plunger 33 is cut off, and the original state is restored.

According to the above configuration, the tips of the rotating members 28, 28 provided on the inner frame 22 are connected to the protrusions 30, 30 and the inclined portion 2.
7, 27, and this rotating member 28, 2
The tip of the wheel 8 is used to prevent the wheel from coming off. Therefore, since the force acts directly on the tips of the rotating members 28, 28, the rotating members 28, 28 can be easily moved.
28 cannot be pried open. Moreover, the rotational position of the inner frame 22 is locked by the drive shaft 34 of the plunger 33 fitting into the engagement recess 32.
Since the locked state cannot be released unless power is supplied to the plunger 33 by a key switch or a switch operated by inserting a coin, it is possible to prevent theft of bicycles, etc. as much as possible.

Also, the rotating members 28, 2 that hold the wheels
8 is located inside the outer frame 21 and inner frame 22, so it is difficult to pry it open, and since the point of force application and the point of force are at the tips of the rotating members 28, 28, it is structurally strong and will not be easily damaged. .

Note that this invention is not limited to the above embodiments. For example, if the plunger 33 is provided on the inner surface of the outer frame 21, damage to the plunger 33 can be prevented, which is further advantageous in preventing theft and extending the service life.

In addition, if a bicycle lock having a well-known drive shaft is provided in place of the plunger 33, and the drive shaft is manually fitted into the engagement recess 32 and pulled out using a key, the power supply and lead It is possible to omit the switch 35 and the like.

Furthermore, the rotating members 28, 28, the inclined parts 27, 2
The position of 7 is not limited to one longitudinal end of the outer frame 21 and inner frame 22. In this case, the direction of inclination of the inclined parts 27, 27 may be changed as appropriate depending on the position thereof.

As detailed above, according to this invention, it is possible to hold the wheels of bicycles etc. with sufficient force, which is advantageous in preventing theft, and also prolongs the service life of the product since it is not easily damaged. It is possible to provide a bicycle parking locking device that is capable of
