Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bicycle parking machine for parking a bicycle, and more particularly to a bicycle parking machine which can be easily and easily operated to lift a bicycle and park the bicycle to reduce a bicycle parking space. is there.

[0002]

2. Description of the Related Art Conventionally, the most popular bicycle parking lot is that bicycles can be simply placed side by side on a flat ground or floor. In this case, the spacing between bicycles, for example, a width of 600 mm per bicycle , You need a flat area multiplied by the length of your bicycle.

In order to save the bicycle parking space, as shown in FIG. 8, the front wheel 5e of the bicycle 5 rides up at an inclination angle of about 35 °.
There is also a bicycle parking lot where a slope 101 is provided and the front wheels 5e of the bicycle 5 can be lifted high to park the bicycle. In this case, the distance between bicycles is set, for example, a width of 600 mm per bicycle,
The area is multiplied by the length of about 1520 mm, which is shorter than the length of the bicycle.

[0004]

As described above, the conventional bicycle parking lot requires a considerably large flat area, which causes a problem that the site area or floor area which can be effectively used for other purposes is narrowed. . In order to reduce the flat area of a bicycle parking lot, it is effective to lift the front wheels of the bicycle as much as possible and hang the bicycle, but in order to suspend the bicycle, the bicycle must be lifted. , You have to do a lot of troublesome and powerful work when you park your bicycle. However, it is not practical to ask for such troublesome and powerful work when parking a bicycle, and it is even terrible for such weak old men and women.

The present invention has been made in view of the above circumstances, and provides a bicycle parking machine in which a bicycle parking space can be reduced by lifting a bicycle and parking the bicycle by a simple and easy operation. That is the purpose.

[0006]

The bicycle parking machine according to the present invention comprises:
In order to achieve the above-mentioned object, a base frame fixed to the ground or floor and an L-shaped one end of which is swingably connected to a base frame so as to be rotatable about a horizontal axis perpendicular to the axis of the base frame. The rocking frame, a free end of the rocking frame that is capable of advancing and retracting, and a sliding frame having an axle engaging portion at the tip, and one end of the rocking frame and the sliding frame are supported to rock the rocking frame. A gas damper whose other end is received by the other of the moving frame and the sliding frame, and one end rotatably connected to the base frame in front of the fulcrum of the swing frame and the other end rotatably connected to the sliding frame. And a support height setting link.

[0007]

After the free end of the swing frame and the sliding frame are horizontal, the bicycle user holds the bicycle handle and pushes the bicycle to engage the axle of the front wheel with the axle engaging portion. ,
When the bicycle is further advanced, the swing frame rotates upward about its fulcrum, and the slide frame is restrained by the height setting link accordingly, and moves to the tip side of the free end of the swing frame. While rotating with the swing frame.

Since the height setting link is longer than the fulcrum-side portion of the swing frame, when the swing frame and the sliding frame are upright, the height setting link is higher than the distance between the fulcrum in the horizontal state and the axle engaging portion. The front axle of the bicycle is lifted and the bicycle is supported by the bicycle in a state in which it is almost suspended.

[0009]

Embodiments of the present invention will be specifically described below with reference to the drawings, but the present invention is not limited to these embodiments. As shown in the side view of FIG. 1 and the front view of FIG. 2, a bicycle parking machine according to an embodiment of the present invention includes a base frame 1 fixed to the ground or floor, and a base frame 1 having one end at the base frame 1. An L-shaped swing frame 2 that is swingably connected about a horizontal axis that is perpendicular to the axis, and a free end portion 2a of the swing frame 2 that is supported so as to be able to move back and forth, and has a left and right end 1 And a sliding frame 4 having a pair of axle engaging portions 3.

The sliding frame 4 has a cylindrical portion 4a slidably fitted on the free end 2a of the swing frame 2 and a bracket 4 at the tip thereof.
The frame parts 4c and 4d are connected to each other via b, and the frame parts 4c and 4b are arranged at right angles to the bracket 4b with a space slightly wider than the width of the front fork 5a of the bicycle 5 in the left-right direction. A pair of right and left linear bone frames 4c which are connected to each other and each of which has an axle engaging portion 3 fixed to each end, and V which has both ends fixed to each axle engaging portion 3 and a central portion fixed to a central portion of the bracket 4b. It consists of a character-shaped frame 4d.

From the fulcrum 6 of the swing frame 2 to the base frame 1,
One end of the height setting link 7 is rotatably connected to a position separated by the same distance as the distance between the fulcrum 6 and the free end portion 2a, and the other end of the height setting link 7 is a sliding frame. 4 is rotatably connected to the cylindrical portion 4a. In the axle engaging portion 3, when the free ends 2a of the sliding frame 4 and the swing frame 2 are positioned horizontally, an engaging groove 8 opened toward the tip end side at the height of the axle 5b of the bicycle 5. And the handle 5c of the bicycle 5 is formed.
3 is grasped with one hand and the other hand is attached to the saddle 5d to advance the front wheel 5e of the bicycle 5 so as to interrupt the front wheel 5e between the axle engaging portions 3, as shown in the explanatory view of FIG. The axle 5a of the front wheel 5e enters into the engaging groove 8 of the axle engaging portion 3.

The free ends 2 of the sliding frame 4 and the swing frame 2
In order to position a horizontally, a stopper 10 that receives the height setting link 7 is provided at the base end portion 2b of the swing frame 2. After inserting the axle 5a of the front wheel 5e of the bicycle 9 into the engagement groove 8 of the axle engaging portion 3, when the bicycle 5 is further advanced, the swing frame 2 swings upward about the fulcrum 6 and slides. Moving frame 4
The axle engaging portion 3 is supported by the height setting link 7 and moves toward the tip of the free end portion 2a while swinging upward together with the free end portion 2a of the swing frame 2.

As a result, the axle 5 of the front wheel 5e of the bicycle 5 is
Since a is supported higher than the distance between the fulcrum 7 and the engaging groove 8, the bicycle 5 is suspended under the saddle 5d so that the rear wheel 5f is hidden. From this suspended state, grasp the handlebar 5c of the bicycle 5 with one hand, attach the other hand to the saddle 5d, and pull out the bicycle 5 rearward.
The rocking frame 2, the sliding frame 4, and the axle engaging portion 3 move in the opposite manner to when they are suspended, and the front wheel 5e of the bicycle 5 is lowered to the ground.

As shown in FIG. 1, a gas damper 9 is arranged across the cylindrical portion 4a of the rocking frame 2 and the free end 2a of the rocking frame 2, and one end of the gas damper 9 rocks. It is fixed to the bracket 4b of the frame 2. This gas damper 9
The other end of the rocking frame 2 is opposed to the base end 2b of the rocking frame 2, and when the free end 2a of the rocking frame 2 and the sliding frame 4 are upright, the base end 2b of the rocking frame 2 is shown. However, the gas damper 9 is received by the base end portion 2b of the swing frame 2 while the free end portion 2a of the swing frame 2 and the sliding frame 4 are positioned horizontally, although they are separated from each other. Is shortened to provide an urging force in the extension direction.

That is, as shown in the sectional view of FIG. 4, the gas damper 9 has a free piston 9b slidably fitted in a cylinder 9a to form a gas chamber 9c filled with compressed air. A piston 9f having an orifice 9e is slidably fitted in a damper chamber 9d formed on the side opposite to the gas chamber 9c of the free piston 9b, and oil is filled so that the piston 9f is opposite to the free piston 9b and the gas chamber 9c. The piston rod 9g continuously extended to the side is guided forward and backward by a rod guide 9h fitted inside the end of the cylindrical body 9a opposite to the gas chamber 9c.

In this embodiment, the end of the gas damper 9 on the gas chamber 9c side is fixed to the bracket 4b of the swing frame 2, and the free end 2a of the swing frame 2 and the sliding frame 4 are positioned horizontally. When the bicycle 5 is lifted, the gas damper 9 is shortened to increase the internal pressure of the gas chamber 9c and generate an urging force in the extension direction. Therefore, when the bicycle 5 is lifted, the urging force is applied to the sliding frame 4 and the axle engaging portion 3. Is moved in the direction of the tip of the free end 2a while swinging upward together with the free end 2a of the swing frame 2, and the bicycle 5 can be easily lifted.

When lowering the hoisted bicycle 5, the other end of the gas damper 9 is received by the base end 2b of the rocking frame 2, and then the free end 2a of the rocking frame 2 and the sliding frame 4 are received.
The sliding frame 4 and the axle engaging portion 3 oppose the movement of the free end portion 2a in the proximal direction while swinging downward together with the free end portion 2a of the swing frame 2 during the time when the free end portion 2a is horizontal. Since the urging force acting in the direction is gradually stored in the gas damper 9,
It is possible to prevent the front wheel 5e of the bicycle 4 from being struck against the ground by gradually suppressing the descending speed of the bicycle.

At the moment when the other end of the gas damper 9 is received by the base end portion 2b of the swing frame 2, the gas damper 9 is
A shocking load acts on the oil, and the oil in the damper chamber 9d tries to flow from the gas chamber 9c side to the opposite side through the orifice 9e. However, this flow is restricted by the orifice 9e, so that it is buffered. Therefore, the impact is not transmitted to the hand on which the bicycle 5 is suspended, and the bicycle 5 can be smoothly lowered.

Further, in this embodiment, as shown in FIG. 1, when the free end portion 2a of the swing frame 2 and the slide frame 4 are erected upright, the engagement groove 8 of the axle engaging portion 3 causes the swing frame to move. The free end portion 2a of the rocking frame 2 and the sliding frame 4 are located in front of the axis of the free end portion 2a and the sliding frame 4 by the dimension A. It is prevented from swinging rearward so that the sliding frame on which the bicycle 5 is lifted does not fall rearward without permission.

As shown in, for example, the plan view of FIG. 5 and the side view of FIG. 6, this bicycle parking machine is provided with a predetermined space P in the left-right direction at a parking space, for example, a space of about 600 mm, which is slightly wider than the width of the handle 5c. Although the bicycles 5 are arranged in parallel, a large number of bicycles 5 can be parked in the left-right direction by arranging the bicycles so that the bicycles can be interrupted in the opposite direction.

As shown in FIG. 6, in this case, the distance between the free end portion 2a of the vertically swinging frame 2 and the axial center of the sliding frame 4 and the rear end of the rear wheel 5f of the bicycle 5 that has been lifted is as follows. For example, 830mm
The distance from the front end of the front wheel 5e of the bicycle 5 to the rear end of the rear wheel 5f can be set to about 1185 mm, and the free end 2a of the swing frame 2 and the sliding frame 4 are laid horizontally. In this state, the horizontal distance from the connection point between the height setting link 7 and the base frame 1 to the engaging groove 8 of the axle engaging portion 3 can be set to about 1055 mm.

Accordingly, in the conventional slope type bicycle parking machine, the distance from the front end of the front wheel 5e of the bicycle 5 to the rear end of the rear wheel 5f needs to be about 1520 mm, but the front and rear dimensions of the bicycle parking lot can be shortened. . As shown in FIG. 7, if this bicycle parking machine is arranged at an angle of about 45 ° with respect to the left-right direction, the front-rear distance from the front end of the front wheel 5e of the bicycle 5 to the rear end of the rear wheel 5f is further shortened. be able to.

In the above embodiment, the connection point of the height setting link 7 to the base frame is separated from the fulcrum 6 by the same distance as the distance between the fulcrum 6 and the free end portion 2a. The connecting point of the setting link 7 to the base frame may be set in front of the fulcrum 6, and, for example, one end of the height setting link 7 may be located at a distance from the fulcrum 6 to the fulcrum 6 and the free end 2a. It may be connected to the base frame 1 at a near distance or at a distance farther than this distance.

The reason why the gas damper 9 is used in the present invention is that it stores an urging force when the gas damper 9 is shortened and has a buffering capacity against a sudden load increase. It is included in the present invention to use an object having such a function. That is,
For example, the present invention also includes the combined use of a shock absorber and a spring that stores a biasing force when shortened.

Further, the gas damper 9 may be supported by the swing frame 2 or both ends thereof may be connected to both the swing frame 2 and the sliding frame 4.

[0026]

As described above, according to the present invention, the base frame fixed to the ground surface or the floor surface and the base frame are rotatably oscillated around the horizontal axis having one end perpendicular to the axis of the base frame. Of the L-shaped swing frame that is movably connected to the swing frame, a slide frame that is supported at the free end of the swing frame so as to be able to move forward and backward, and has an axle engaging portion at the tip, and the swing frame and the slide frame. One end is supported on one side, and the other end of the swing frame and the sliding frame is received on the other side, and one end is located at a position more than the distance between the fulcrum and the free end of the oscillating frame. A support height setting link rotatably connected to the base frame and the other end rotatably connected to the sliding frame.

Thus, the bicycle can be hoisted by the simple work of engaging the axle of the front wheel of the bicycle with the axle engaging portion and moving the bicycle forward, and the simple work of pulling the hoisted bicycle backward. You can hang it with. Further, by providing a gas damper, when the free end of the swing frame and the sliding frame are positioned horizontally, the free end of the slide frame and the axle engaging part are swung upward together with the free end of the swing frame. By applying an urging force that works in the direction of moving the front end of the portion, the bicycle can be easily lifted, and the front wheels can be prevented from hitting the ground or floor when hanging.

Moreover, since the bicycle can be parked upright so that its rear wheels can be hidden under the saddle, the bicycle parking space can be shortened.
