Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a bicycle parking device which is installed in a bicycle parking space and supports the bicycle in a bicycle parking state.

[0002]

BACKGROUND ART In recent years, bicycles have been used more and more not only as a foot for commuting or attending school, but also as a leisure article. In addition, along with this, construction of bicycle parking lots is being promoted at stations, public facilities, parks, various shops, sightseeing spots, etc. However, bicycles are often parked because the parking condition tends to be complicated. It is difficult to use space efficiently,
There are problems such as spoiling the aesthetics of the vicinity, and it is easy to put in and take out the bicycle, and because the bicycle stand is unstable and easy to fall, there is a problem that if one falls down, it becomes easy to play shogi. Was also bad.

Therefore, for the purpose of parking many bicycles in a space-efficient manner and orderly for easy loading and unloading, various bicycles have been conventionally installed in a bicycle parking lot to support the bicycles in a parked state. A bicycle parking device has been devised. And, as a kind of such a bicycle parking device, Japanese Utility Model Publication No. 56-52138 and the like provide a groove on the surface of a block installed on the surface of the earth, and a front wheel of a bicycle is fitted into the groove to stand up. There is disclosed a bicycle parking device that supports a bicycle in a parked state by holding the bicycle in a parking state.

However, in such a conventional bicycle parking apparatus, if the width of the bicycle wheel is thin, the holding by the groove may become unstable, and the bicycle may be greatly inclined or fall out and fall. If the width of the wheel is thick, it cannot be held without entering the groove. Therefore, if the width of the wheel of the bicycle does not match the width of the groove, the bicycle cannot be supported stably. There was a problem. Especially in recent years, the number of bicycles called mountain bikes with extremely wide wheels and the number of bicycles with various wheel widths have increased due to the design.Therefore, conventional bicycle parking devices are not enough to handle this. The current situation is that they are disappearing.

Japanese Utility Model Publication No. 54-27728 proposes a device in which the gap between a pair of vertical rods for holding and holding the front wheels can be adjusted according to the tire width of the bicycle. Then, when adjusting the gap of the vertical rod,
This is not practical because it requires loosening multiple bolts and nuts one by one. In addition, actual public Sho 54-
According to Japanese Patent No. 27726, a narrow elongated hole extending in the circumferential direction is provided in the center of the bottom of an arc-shaped trough that fits and holds a front wheel of a bicycle. There has been proposed a bicycle parking device that is fitted and held in a long hole having a width.However, in such a device, when the width dimension of the front wheel is narrow, the front wheel is held only by the opening end face of the long hole. Therefore, it is difficult to secure a sufficient holding area for the front wheels, and the bicycle tends to be greatly tilted or toppled, and in addition, the bicycle parking device body is subject to concentrated loads and is easily damaged. I was doing it.

[0006]

The present invention has been made in view of the above circumstances, and the problem to be solved is that bicycles of various wheel widths can be favorably supported in a parked state. At the same time, another object is to provide a bicycle parking device having a simple structure and excellent usability.

[0007]

In order to solve such a problem, a feature of the present invention is that each has a substantially arcuate shape of a predetermined width that curves forward and rises upward, and keeps a predetermined distance from each other. An outer surface support portion extending in the opposing direction of the pair of side wall portions is provided between the opposed surfaces of the pair of side wall portions that are spaced apart and face each other, and the outer surface support portion supports the outer peripheral surface of the front wheel of the bicycle. The front wheel is held at a fixed position in the front-rear direction, and a side surface support portion is provided on the inner peripheral side of the outer surface support portion so as to face each other in the opposing direction of the pair of side wall portions. In a bicycle parking device that supports the bicycle in a parked state by supporting the front wheel in a standing state,
The side surface supporting portion is formed in a plurality of steps such that the distance between the facing surfaces gradually increases from the outer peripheral side to the inner peripheral side of the side wall portion, and a step portion is formed in the interstage portion of the side surface supporting portion. By doing so, the outer peripheral surface of the front wheel of the bicycle, which is thicker than the distance between the facing surfaces of the side surface supporting portions located on the outer peripheral side of the step portion, is supported, and the inner peripheral side of the step portion is provided. The side peripheral portion of the front wheel supports the side peripheral surface of the front wheel to support the bicycle in a parked state.

In the bicycle parking apparatus having the structure according to the present invention, the front wheel having a large wheel width is located on the inner peripheral side of the outer surface supporting portion and the side surface supporting portion for holding the front wheel having a small wheel width. Since it is possible to form the step portion and the side surface supporting portion to be made narrow, both the holding portion of the thin front wheel and the holding portion of the thick front wheel are continuous in the circumferential direction of the side wall portion or are divided into a plurality of locations in the circumferential direction. Then, it can be formed at any position.

Therefore, it is possible to advantageously secure a sufficient holding area in both the holding portion of the thin front wheel and the holding portion of the thick front wheel, and various bicycles having front wheels of various thicknesses can be obtained. Both of them can stably support the parking state.

It is sufficient that the side surface supporting portions having the distances between the opposed surfaces are formed in at least two steps, and at least one step portion is formed accordingly, but a wider wheel width is required. When it is necessary to adapt to the front wheels of the bicycle, or to further improve the stability of the supported bicycle,
It is also possible to form the side surface supporting portion having three or more facing surface distances and two or more step portions.

Further, the outer surface supporting portion, the side surface supporting portion and the step portion which constitute the supporting surface for the outer periphery and the side periphery of the front wheel are
Although it may be formed at any position, preferably, as described in claim 2, the outer surface support portion and the side surface support portion and the step portion are located at least at both end portions in the circumferential direction of the side wall portion. In addition, it is formed at a plurality of positions in the circumferential direction in a divided form.

According to the structure described in claim 2, the holding force at a fixed position with respect to the front wheel of the bicycle can be effectively exerted by the small number of supporting surfaces, and the simplification of the shape or structure and the bicycle can be achieved. The support function for the parking state of
Both can be realized in a compatible manner.

The outer surface supporting portion, the side surface supporting portion and the stepped portion may be retrofitted to the side wall portion as a separate structure, but it is preferable that the outer surface supporting portion, the side surface supporting portion and the step portion are paired as described below. The side wall portion of is integrally formed including the outer surface support portion, the side surface support portion, and the step portion.

According to the structure described in claim 3, the structure of the bicycle parking apparatus according to the present invention can be further simplified, and the manufacturability and the cost can be improved. The material is not particularly limited as long as it has a certain strength and durability, but from the viewpoint of manufacturability and cost, aluminum alloy, synthetic resin (including waste plastic), etc. Is preferably adopted.

Furthermore, the outer surface supporting portion, the side surface supporting portion, and the step portion are fixedly provided to the side wall portion, and are brought into contact with the outer peripheral surface or the side peripheral surface of the front wheel of the bicycle so as to have a constant support. Any material can be used as long as it can exert its force, and the specific shape and structure are not limited in any way. For example, claim 4
The rib-shaped projection is formed by forming the outer surface supporting portion across the pair of side wall portions and forming the side surface supporting portion and the step portion on the inner surface of each side wall portion. The structure formed by the above can be suitably adopted.

According to the structure described in claim 4, the outer surface supporting portion, the side surface supporting portion, and the contact supporting surface of the step portion are prevented from increasing significantly while the apparatus weight is increased.
In addition to being able to be formed over a wide range, the rib structure can also improve the rigidity of the device.

Further, in the bicycle parking apparatus according to the present invention,
As described in claim 5, a connection part for connecting to another same device arranged in parallel at a predetermined distance from each other in a fixed relative position can be preferably employed.

According to the structure of the fifth aspect, it is easy to install a plurality of bicycle parking devices in parallel, and by keeping a plurality of bicycles in a parked state in an orderly manner, a parking space is provided. Both the effective use of the bicycle and the improvement of usability by facilitating the putting in and out of the bicycle can be advantageously achieved.

The structure of the connecting portion is not particularly limited, and a fixing portion structure for fixing to a continuously formed installation base with a bolt or the like, or a bicycle parking device arranged adjacent to the fixing portion structure. Various connecting structures such as a fixing portion structure for directly connecting and fixing can be adopted.
