The accommodating means includes a pair of left and right connecting rods (12) and a fluid pressure cylinder (15) using a fluid such as air or oil as a working fluid.

The connecting rod (12) is a rod having a bendable portion (31) in the middle in the length direction, and the bendable portion (31) is formed of a chain or the like.
One end of the connecting rod (12) is rotatably attached to a pin (32) connecting the reinforcing plate (7) of the elevating body (2).
The other end of the connecting rod (12) is rotatably attached to a metal fitting (33) provided in the middle of the bicycle mounting table (5) in the length direction.
As a result, the connecting rod (12) connects the elevating body (2) and the bicycle mount (5) so as to incline downward from the rear to the front (see FIG. 1).

The fluid pressure cylinder (15) is composed of a gas cylinder, a hydraulic cylinder, or the like, and is arranged so that the rod (34) expands and contracts substantially in the vertical direction.
The base end portion of the fluid pressure cylinder (15) is rotatably attached to the front plate (8) of the elevating body (2). Specifically, it is attached to a pair of left and right gas placket (16) at a position above the attachment portion (13) of the bicycle mounting base (5) and near one end of the connecting rod (12). ing.
The tip of the fluid pressure cylinder (15) (the tip of the rod (34)) is rotatably attached to the bicycle mount (5) via an extension member (35). Specifically, the bicycle mounting table (5) has a front end portion slightly rearward of the mounting portion (13), and an extension member (35) extending upward from the front end portion is attached.

The extending member (35) is bent in an "L" shape in a side view and has a through hole (36) at one end of the extending member (35) at the other end of the side plate so as to connect the pair of left and right side plates. It is composed of a cylindrical portion provided.
A pin (14) is inserted through the cylindrical portion. This pin (14) is also inserted through the mounting portion (13) of the reinforcing plate (7) of the elevating body (2) and the bicycle mount (5), and rotates the bicycle mount (5) upward. It becomes a rotation fulcrum when making it.
A pin (37) is inserted into the through hole (36) of the extending member (35). The pin (37) is inserted into a hole (38) provided in the tip portion (tip portion of the rod (34)) of the fluid pressure cylinder (15), and the extension member (35) and the fluid pressure cylinder (35) are inserted. It is connected to the tip of the rod (34) of 15).

Next, the operation of the accommodating means will be described.
As shown in FIG. 1, the bicycle mounting table (5) is in the horizontal state in the initial state.
In this state, as disclosed in Patent Document 1, a force for shortening the rod (34) acts on the fluid pressure cylinder (15), and the extension member (35) is pulled upward. There is. As a result, a force that tends to rotate downward acts on the bicycle mounting table (5), but the connecting rod (12) prevents the bicycle from rotating downward from the horizontal state.

From the state shown in FIG. 1, when the user holds the front part of the bicycle mounting table (5) with no bicycle mounted and pushes it upward, the bicycle mounting table (5) is attached to the elevating body (2). It rotates upward with the pin (14) of the portion (13) as a fulcrum.
As the bicycle mounting table (5) rotates upward, the rod (34) of the fluid pressure cylinder (15) extends, and the bending angle of the bendable portion (31) of the connecting rod (12) becomes large. As a result, the angle of the bicycle mount (5) with respect to the floor also increases.
Then, when the bicycle mounting table (5) rotates 90 ° upward, the bicycle mounting table (5) is housed in the slit (6) (inside the support column (1)).

By accommodating the bicycle mounting table (5) in the slit (6) and accommodating it in the support column (1) in this way, it is possible to make the bicycle parking device extremely compact when not in use or during transportation. Further, when the bicycle mounting table (5) is rotated upward, a resistance force is applied by the fluid pressure cylinder (15), so that the bicycle mounting table (5) may be inadvertently rotated upward during use. It is prevented and safe. Further, the connecting rod (12) can surely prevent the bicycle mounting table (5) from rotating below the reference position (horizontal position).

Further, since the bicycle mounting table (5) can be accommodated in the slit (6) by rotating it upward with the mounting portion (13) attached to the elevating body (2) as a fulcrum, the bicycle is mounted. When not in the state, the bicycle mount (5) is accommodated in the slit (6) and does not rise. Therefore, it is not necessary to provide a switching mechanism, and the structure can be simplified and the device can be miniaturized.

In the present invention, if at least the support column (1) and the elevating body (2) are formed of a steel plate hot-dip galvanized with zinc-aluminum 6% -magnesium 3% called a ZAM steel plate, the corrosion resistance becomes excellent. preferable. However, the material is not limited to this.

In the two-stage bicycle parking device according to the present invention, similarly to the conventional two-stage bicycle parking device (see, for example, Patent Document 1 above), a plurality of upper storage units are installed side by side in the width direction, and the upper storage units are installed below the upper storage unit. Is provided with a lower storage section (not shown).
