BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a two-stage bicycle parking apparatus capable of vertically parking a bicycle in a bicycle parking space.

[0002]

2. Description of the Related Art Conventionally, in a two-stage bicycle parking apparatus, a horizontal rail is fixed on a pillar, and an upper bicycle bearing rail is detachably attached to this horizontal rail. When it is inserted into the rail, it keeps a substantially horizontal state, and when it is pulled out from the horizontal rail, the rear end side of the upper bicycle support rail can be inclined to a substantially grounded state. Therefore, with the upper bicycle bearing rail pulled out from the horizontal rail and its rear end lowered, the bicycle is placed on the upper bicycle bearing rail, and then the right end side of the upper bicycle bearing rail is mounted by hand. You can park the bicycle at a high place by lifting it with the bicycle and making it almost horizontal, and then inserting the upper bicycle support rail into the horizontal race.If you want to lower this bicycle, reverse the above operation. .

However, the above operation has a problem that a user needs a large amount of force to lift the bicycle, which may be difficult for a child or a woman to operate. Also,
There is a problem that if the user releases the hand during the operation of lowering the bicycle, the upper bicycle support rail and the bicycle may suddenly rotate in a falling state, which may be dangerous.

In addition, attempts have been made to automate the operation of raising and lowering the bicycle to the upper stage, and the inventors of the present invention have previously proposed an electric two-stage bicycle parking device. However, the motor is used to raise the bicycle to a predetermined height. Has a problem in that a compact device requires a high-output motor, which is expensive.

[0005]

SUMMARY OF THE INVENTION Therefore, the present invention has been made to solve the above-mentioned problems, and mechanically bears the load of a bicycle with a simple device to improve the operability of the bicycle to the upper stage. It is an object of the present invention to provide a two-stage bicycle parking device that can be smoothly lifted and lowered.

[0006]

According to the present invention, in order to achieve the above-mentioned object, a bottom surface portion 21, both side surface portions 22 and 22, and an inner side of upper ends of the both side surface portions 22 and 22 are provided on an upper portion of a columnar body 10. By fixing the rectangular horizontal rail 20 having a cross-sectional shape having a cutout of a predetermined width at the center of the upper surface with the bent upper surface portions 23, 23, the upper bicycle mounting rail 30 which is detachably attached to the horizontal rail 20 is The upper bicycle mounting rail 30 is a pair of wheels provided at the rear end portion of the horizontal rail 20. The upper bicycle mounting rail 30 has a substantially U-shaped cross section and is formed by continuously connecting outwardly bent flange portions 31, 31 to both upper ends thereof. The flange portions 31 and 31 are mounted on the bodies 1 and 1, and the upper bicycle mounting rail 30 is movable in the inserting / removing direction.
Further, the wheel bodies 1 and 1 are mounted on the horizontal rail 20 so as to be rotatable about the central axis, and further, at the tip of the upper bicycle mounting rail 30, the upper surface portions 23, 23 of the horizontal rail 20 are mounted. One end of an arm 41 which can freely move in and out of the horizontal rail 20 is pivotally attached to the arm 4 through the notch.
At the other end of 1, there is rotatably mounted a wheel body 42 located forward of the tip of the upper bicycle mounting rail 30 and guided by the horizontal rail 20 to roll.
The lower end of a vertical arm 43 protruding above the horizontal rail 20 is pivotally attached to the upper end of the vertical rail 43, and the upper end of the vertical arm 43 and the tip of the upper bicycle mounting rail 30 are retracted by the rod to hermetically store. The fluid is compressed by a buffer cylinder body 44, and the tip of the upper-stage bicycle mounting rail 30 and the midway portion of the vertical arm 43 prevent the vertical arm 43 from collapsing and the upper-stage bicycle mounting rail 3
When 0 is pulled out from the horizontal rail 20 and rotated so that its rear end side is located at the lowest position, the buffer cylinder body 4
4 and the crossing angle L1 between the upper bicycle mounting rail 30 is 18
This is a technical measure in which the link bodies 45 are connected so that the angle becomes 0 degrees or more.

Therefore, the two-stage bicycle parking apparatus of the present invention has an effect that the bicycle can be parked vertically in two stages by riding the bicycle on the upper bicycle mounting rail 30 held by the horizontal rail 20 provided at a high place. The presenting is the same action as the conventional two-stage bicycle parking device, but since the cushioning cylinder body 44 is provided, when the rear end of the upper bicycle mounting rail 30 is rotated downward when the bicycle is lowered, the tip side When the bicycle is rotated upward, the buffer cylinder body 44 is retracted, the load is converted into a compressive force of the fluid and absorbed to exert a buffer effect, and a sudden drop occurs even if the hand is released while lowering the upper bicycle. Exerts the effect of suppressing.

On the contrary, when the bicycle is lifted, a part of the load is borne by the fluid pressure accumulated in the buffer cylinder body 44, so that the bicycle can be lifted with a small force. When the rear end of the upper bicycle mounting rail 30 is rotating downward, the fluid pressure accumulated in the buffer cylinder body 44 acts to lift the rear end of the upper bicycle mounting rail 30 upward. According to the present invention, when the rear end side of the upper bicycle mounting rail 30 is rotated so as to be located at the lowermost position, the buffer cylinder body 44 and the upper bicycle mounting rail 30 are arranged.
Since the link body 45 is set so that the intersection angle L1 with the crossing angle L1 is 180 degrees or more, the upper bicycle mounting rail 30
When the rear end side is located at the lowest position, the buffer cylinder body 4
The fluid pressure accumulated in 4 acts so as to urge the rear side of the upper bicycle mounting rail 30 further downward, and even if no bicycle is mounted on the upper bicycle mounting rail 30, It acts to prevent the rear end side of the bicycle mounting rail 30 from naturally rising upward.

Therefore, in the above, the upper bicycle mounting rail 30
It is said that the fluid pressure accumulated in the cushioning cylinder body 44 bears a part of the load when the bicycle mounted on the bicycle is lifted, but when the rear end of the upper bicycle mounting rail 30 is lowered to the lowest position. The load is not burdened, and on the contrary, it acts so that a part of the fluid pressure is added to the load, but by manually lifting the rear end of the upper bicycle mounting rail 30, the buffer cylinder body 44 and the upper bicycle mounting rail 30 are loaded. Intersection angle L1 with
Is less than 180 degrees, the fluid pressure bears a part of the weight.

Embodiments of the present invention will now be described in detail with reference to the accompanying drawings. In the figure, 10 is a pillar, and a plurality of the pillars 10 are arranged in a row in a parking space S in a row (arranged in the front direction of FIGS. 1 and 2). In addition, a plurality of the pillars 10, 10, 10, ...
As shown in (1), the height of the height of every other piece and the height of the height of every other piece are alternately arranged, whereby the juxtaposition interval can be narrowed. In other words, the position where the bicycle has the widest width is the handle portion, so by changing the height of this handle with the adjacent bicycle, it becomes possible to place the bicycle side by side at a narrower interval than the width of the handle. It is a thing.

Then, the bottom portion 2 is provided on the top of the pillar 10.
1, the side surface portions 22 and 22, and the upper surface portions 23 and 23 that are bent inward from the upper ends of the both side surface portions 22 and 22, and have a rectangular cross section with a cutout of a predetermined width at the center of the upper surface portion (FIG. 4). The horizontal rail 20 of the reference) is fixed. This horizontal rail 20 is for inserting the tip side (left side of FIGS. 1 and 2) of an upper bicycle mounting rail 30 described later to hold the upper bicycle mounting rail 30 in a substantially horizontal state and to pull out the upper bicycle. The front end side of the mounting rail 30 is locked at the rear end portion of the horizontal rail 20, and the upper bicycle mounting rail 3
It is used to hold the rear end side of 0 (right side in FIGS. 1 and 2) at an angle (as indicated by a thin line in FIGS. 1 and 2) so as to contact the floor surface of the parking space S.

The upper bicycle mounting rail 30 removably attached to the horizontal rail 20 has a substantially U-shaped cross section, and the flange portion 3 is bent outward at both upper ends thereof.
1, 31 are arranged in series. That is, the upper bicycle mounting rail 30 has a cross-sectional shape shown in FIGS. 4 to 6, and the bicycle wheel is inserted into the U-shaped portion to hold the bicycle. In FIG. 5, the upper bicycle mounting rail 30 has a U-shaped upper portion with continuous wide standing wall portions 32 and 32, and an outwardly bent flange portion 31 at the upper ends of the standing wall portions 32 and 32. , 31 are connected in series, but the lower part of the high-stage bicycle mounting rail 30 holds a narrow-width tire such as a sports bicycle and the upper part holds a normal bicycle having a wide tire width. is there. In addition, FIG. 6 shows an example in which the flange portions 31 and 31 are formed by separately welding a steel mold, and a steel mold having a U-shaped cross section is formed on both outer sides of the upper bicycle mounting rail 30 having a U-shaped cross section. Three
0a and 30a (groove type steel) are welded and stopped with their openings facing outward. Needless to say, mountain steel (angle) may be used in place of the U-shaped steels 30a and 30a (groove type steel) having a substantially U-shaped cross section.

A wheel holding frame is provided on the leading end side and the rear end side of the upper-stage bicycle mounting rail 30 to prevent the wheels of the bicycle from toppling over and to prevent the wheels from falling off in the longitudinal direction of the upper-stage bicycle mounting rail 30. Although 32 and 33 are provided, conventionally known wheel holding frames may be used as the wheel holding frames 32 and 33. In addition, a handlebar 3 is provided at the rear of the upper bicycle mounting rail 30.
4 and a grounding foot 35 are provided, but this handle 3
4 and the grounding foot 35 may be conventionally known ones.

Then, the above-mentioned upper bicycle mounting rail 30
Is configured such that the flange portions 31, 31 are mounted on the pair of wheel bodies 1, 1 provided at the rear end portion of the horizontal rail 20, and the upper bicycle mounting rail 30 is movable in the inserting / removing direction. The wheel bodies 1 and 1 are mounted on the horizontal rail 20 in a rotatable state around the center axis. That is, a pair of wheel bodies 1, 1 are provided at the rear end portion of the horizontal rail 20, and the flange portions 31, 31 of the upper-stage bicycle mounting rail 30 are placed on the wheel bodies 1, 1. , The upper bicycle mounting rail 3 in a horizontal state
0 is movable in the inserting / removing direction with respect to the fixed horizontal rail 20 by rotating the wheel bodies 1 and 1. Further, the upper bicycle mounting rail 30 pulled out from the horizontal rail 20 is configured such that its rear end side can be rotated downward with the wheel bodies 1 and 1 as a rotation center axis.
In addition, this upper bicycle mounting rail 30 is a horizontal rail 20.
The upper bicycle mounting rail 30 so that it does not fall out further
End plate 36 that serves as a stopper at the tip of the
(See FIG. 3) should be attached.

At one end of the upper bicycle mounting rail 30, one end of an arm 41 which can be freely moved into and out of the horizontal rail 20 is pivotally attached to the tip of the horizontal rail 20 through a notch between the upper surface portions 23 of the horizontal rail 20. At the other end of the arm 41, there is rotatably attached a wheel body 42 positioned forward of the tip of the upper bicycle mounting rail 30 and guided by the horizontal rail 20 to roll.
The lower end of a vertical arm 43 projecting above the horizontal rail 20 is pivotally attached to the axle 42a of the wheel 42, and the upper end of the vertical arm 43 and the upper bicycle mounting rail 30 are attached.
Is connected to the tip end of the buffer cylinder 44 by a buffer cylinder body 44 which compresses the fluid which is hermetically enclosed by the rod retracting. As shown most clearly in FIG. 4, the wheel body 42 rolls in the horizontal rail 20, but does not go out of the horizontal rail 20. When the end pivots downward, the tip side pivots upward as indicated by an arrow P1 in FIG. 3 to shorten the distance from the upper end of the vertical arm 43.

However, even if the tip side of the upper bicycle mounting rail 30 is rotated upward, if the vertical arm 43 falls freely, the tip side of the upper bicycle mounting rail 30 and the upper end of the vertical arm 43 are brought into contact with each other. As a result, it becomes possible to maintain a predetermined distance. Therefore, in the present invention, the tip of the upper bicycle mounting rail 30 and the middle portion of the vertical arm 43 prevent the vertical arm 43 from collapsing, and the upper bicycle mounting rail 30 is pulled out from the horizontal rail 20 to the rear end side. When pivoted to the lowermost position, the linking body 45 connects the cushion cylinder body 44 and the upper bicycle mounting rail 30 so that the intersection angle L1 is 180 degrees or more. That is, the arm 41 and the link body 45 are provided on the tip side of the upper bicycle mounting rail 30.
The vertical arm body 43 is pivotally held by the and, and even if the tip end side of the upper bicycle mounting rail 30 rotates upward, the lower end of the vertical arm body 43 is supported by the wheel body 42 at the horizontal rail 20. When the tip side of the upper bicycle mounting rail 30 is rotated upward, the distance from the upper end of the vertical arm 43 is shortened, that is, The rod of the buffer cylinder body 44 is adapted to be retracted while increasing the fluid pressure of the fluid contained in the buffer cylinder body 44.

When the upper bicycle mounting rail 30 is rotated so that the upper bicycle mounting rail 30 is pulled out from the horizontal rail 20 and the rear end thereof is located at the lowermost position, the link body 45 and the upper bicycle mounting rail 30 are rotated. The intersection angle L1 with 30 is 180 degrees or more. However, this intersection angle L1
However, the setting of the intersection angle L1 can be adjusted by the mounting positional relationship among the arm 41, the link body 45, the vertical arm body 43, and the buffer cylinder body 44.

Therefore, according to the present invention, in order to lower the mounted bicycle from the state shown in FIG. 1, first, with the handle 34 in hand, the upper bicycle mounting rail 30 is pulled out in the direction of arrow P2. Then, at the beginning of the drawer, the upper bicycle mounting rail 3
Since the center of gravity of 0 is on the horizontal rail 20, the upper-stage bicycle mounting rail 30 is pulled out in a substantially horizontal direction with the wheel bodies 1 and 1 and the wheels 42 rolling. Then, when a certain distance is pulled out, the center of gravity deviates from the top of the horizontal rail 20 and moves to the rear of the horizontal rail 20, so that the rear end side of the high-stage bicycle mounting rail 30 has a force to rotate downward. The force by which the rear end side of the high-stage bicycle mounting rail 30 rotates downward due to the load causes the tip side of the high-stage bicycle mounting rail 30 to rotate upward, causing the cushioning cylinder body 44 to retract. Due to the cushioning action of the cushioning cylinder body 44, the rear end side of the high stage bicycle mounting rail 30 is slowly rotated downward.

When the rear end side of the high-stage bicycle mounting rail 30 comes into contact with the floor surface of the parking space S or the like, the bicycle can be lowered from above the inclined high-stage bicycle mounting rail 30. . Then, when the bicycle is lowered, the load becomes small, so that the rear end of the high-stage bicycle mounting rail 30 is likely to be lifted by the fluid pressure compressed in the buffer cylinder body 44. When the rear end side of the bicycle mounting rail 30 is in contact with the floor surface of the parking space S or the like, this force acts in the opposite direction, and even if the hand is released from the handle 34, the high stage bicycle mounting rail 30 does not naturally lift. It is designed not to be.

That is, according to the present invention, when the upper bicycle mounting rail 30 is rotated by the link body 45 so that the upper bicycle mounting rail 30 is pulled out from the horizontal rail 20 and the rear end side thereof is located at the lowermost position, the buffer cylinder body 44 and the upper stage are mounted. Since the intersection angle L1 with the bicycle mounting rail 30 is set to 180 degrees or more, in the state shown by the thin line in FIG. It works in the direction of pressing against a surface.

Next, to park the bicycle on the upper stage, the bicycle is placed on the upper stage bicycle mounting rail 30 which is pulled out from the horizontal rail 20 and inclined. Then, using the handle 34 as a hand, the rear end side of the high-stage bicycle mounting rail 30 is lifted. Then, the load of the bicycle or the like and the pressing force of the buffer cylinder body 44 are initially applied, so it is heavy, but when it is lifted a little and the intersection angle L1 between the buffer cylinder body 44 and the upper bicycle mounting rail 30 becomes 180 degrees or less, this time. Since the buffer cylinder body 44 tries to lift the rear of the high-stage bicycle mounting rail 30, the high-stage bicycle mounting rail 30 on which the bicycle is lightly lifted can be lifted to a substantially horizontal state. And
When the upper bicycle mounting rail 30 is lifted up to a substantially horizontal state, the high bicycle mounting rail 30 is inserted in the direction opposite to the arrow P of FIG. 1 to complete the parking of the bicycle on the high stage. .

The linking body 45 is arranged so that the intersection angle L1 between the cushioning cylinder body 44 and the upper bicycle mounting rail 30 becomes 180 degrees or more when the rearmost side is pulled out further and rotated so as to be located at the lowermost position. What is done is the same configuration as in claim 1.

[0033]

According to the first and second aspects of the present invention, when the bicycle is lowered, the buffer cylinder body 44 suppresses the fall of the sudden attack, and when the bicycle is lifted, the buffer cylinder body 44 is lifted.
It is possible to provide a two-stage bicycle parking device that can be lifted lightly by bearing a part of the load.

The present invention also relates to the upper bicycle mounting rail 3
The link body 45 is set so that the intersection angle L1 between the cushioning cylinder body 44 and the upper bicycle mounting rail 30 becomes 180 degrees or more when the rear end side of 0 is rotated to the lowermost position. Therefore, when the rear end side of the upper-stage bicycle mounting rail 30 is located at the lowermost position, the fluid pressure accumulated in the buffer cylinder body 44 is urged downward toward the rear end side of the upper-stage bicycle mounting rail 30. Thus, it is possible to provide a two-stage bicycle-parking device in which the rear end side of the upper-stage bicycle mounting rail 30 does not naturally rise even when the hand is released.

Particularly, in addition to the above effects, the invention of claim 2
The mutual length relationship between the horizontal rail 20 and the upper bicycle mounting rail 30 is such that the wheel bodies 1 and 1 are the upper bicycle mounting rail in a state in which the tip of the upper bicycle mounting rail 30 is inserted all the way into the horizontal rail 20. Since it is set so as to be located rearward of the center of the longitudinal direction of 30, it is possible to provide a two-stage bicycle-parking device capable of preventing the upper-stage bicycle mounting rail 30 from spontaneously dropping even if an unexpected external force is applied due to an earthquake or the like. is there.

In addition, since the present invention is provided with the end plate 36, it is possible to prevent the upper bicycle mounting rail 30 from falling off, and the user should pull out the high bicycle mounting rail 30 to the end. It is possible to provide a two-stage bicycle parking apparatus which is known when the wheel bodies 1 and 1 collide with the end plate 36 and which is improved in operability.
