DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below in detail with reference to the drawings. FIG. 1 is an explanatory side view showing a state of parking a bicycle of an up-down two-stage three-dimensional bicycle parking apparatus as one embodiment of the present invention.

[0005] The three-dimensional bicycle parking device M of the present invention has a substantially U-shaped integrally continuous frame f, an upper horizontal portion of the frame f forms an upper fixed rail 2, and a lower horizontal portion has
The lower fixed rail 4 is formed. The upper moving rail 1 is slidably held in the upper fixed rail 2. The front portions of the upper and lower fixed rails 2 and 4 are connected by a support post 3, and the support post 3 is provided with parallel left and right plates 3a, 3a provided at intervals as shown in FIG. Are sandwiched from the left and right.

That is, the column 3 is an upper fixed rail 2
Is inclined forward so that the front end of the lower fixed rail 4 is located slightly forward of the front end of the lower fixed rail 4, and the inclination angle θ is about 5 to 5.
The angle may be 30 degrees. More preferably, it is 10 to 20 degrees. Curved portions 3b and 3c are formed on the upper and lower sides of the column 3, and contact the spokes 8 of the front wheel along the curved portion 3c at the lower portion. Instead of the lower fixed rail 4, an inclined fixed rail 50 may be attached as shown by a two-dot chain line in FIG.

As shown in FIG. 4, the bicycle 9 on the upper tier is pulled out of the upper movable rail 1 toward the front of the upper fixed rail 2, and the rear side of the movable rail 1 is lowered to contact the ground.
Is lifted into the groove of the moving rail 1 and pushed up to the front wheel support 20 provided at the front of the moving rail 1, and the rear wheel of the bicycle 9 is lifted to provide the rear wheel supporting 21 provided at the rear of the moving rail 1. To be stored. Then, the moving rail 1 is lifted and pushed into the upper fixed rail 2 until it is locked, so that it can be stored. In addition, at the rear end of the upper fixed rail 2,
An elastic plate 22 is provided, and the elastic plate 22 holds a guide roller 23 and functions as a guide when the moving rail 1 is taken in and out.

Next, the bicycle 10 parked in the lower berth has a column in which the front wheel of the bicycle 10 is inserted into the groove of the lower berth fixed rail and pushed forward to fix the lower part to the lower berth fixed rail and support the upper berth fixed rail in the upper part. The front wheel of the bicycle 10 is passed through the gap 3 and pushed in until the front wheel spokes 8 come into contact with the left and right plates 3a, 3a.

[0009] The three-dimensional curved surface formed by the front wheel spokes 8 of the bicycle 10 is such that each of the spokes 8 is alternately arranged in the circumferential direction from the tire holding frame (rim) obliquely to both ends of the front wheel axle. It stretches out and is knotted at the axle. It is shaped like two flat cones with the two ends of the axle as vertices superimposed on both bottom surfaces. For this reason, when the front wheel is inserted into the support 3, approximately 1/3 of the spokes corresponding to the angle Wθ of all the spokes are
Comes into contact with the curve along the curved portion 3c. Therefore, there are many contact points between the front wheel spokes 8 of the bicycle 10 and the pillars 3, and the stability of the bicycle 10 is greatly improved as compared with the conventional device. Note that the support structure having such a curved portion 3c (a structure in which the front wheel is sandwiched and fixed) need not be a three-dimensional bicycle parking device that vertically parks a bicycle, but can be applied to a single-stage bicycle parking device. It is.

Further, the support 3 is moved forward by about 5 to the vertical.
Because the bicycle 10 is tilted by 30 degrees, the position of the bicycle 10 stored in the lower berth is flush with the position of the bicycle 9 stored in the upper tier in the front-rear relationship, and the difference between the positions of the upper and lower tiers stored by the conventional three-dimensional bicycle parking device is different. The installation area can be reduced by L. Furthermore, when the bicycle 10 is stored in the lower stage, a large upper space of the front wheel can be ensured, and the front portion of the basket 7 attached to the upper portion of the front wheel in the conventional device may be damaged by contact with the column 3. There was, but that fear could be resolved.

[0011]

Since the present invention is constructed as described above, the position of the bicycle 10 stored in the lower tier is flush with the position of the bicycle 9 stored in the upper tier, and the bicycle 10 is stored by the conventional three-dimensional bicycle parking device. The installation area can be reduced by the difference L between the positions of the upper and lower bicycles. In addition, since the column 3 is inclined forward and upward and has a curved portion at the lower portion, the contact point between the spoke 8 and the column 3 constituting the conical shape of the front wheel of the bicycle 10. Is increased as compared with the conventional method, and the storage stability of the bicycle is further increased.

Further, when the lower bicycle 10 is stored, the pillar 3 in the present invention is inclined forward and has a curved portion at the upper part. Therefore, there is no possibility that the basket 7 comes into contact with the column 3 and is damaged.
