2. Description of the Related Art There are various types of bicycle parking apparatus for parking a bicycle in two steps, but because of its relatively simple structure, it can be placed horizontally at a predetermined height above the floor. A fixed frame supported and a movable frame that can be moved back and forth along the fixed frame are provided, the movable frame is retracted to the front end side of the fixed frame, and the rear end side is rotated downward to mount the bicycle. After that, a type in which the rear end side of the movable frame is rotated upward to a horizontal position and is moved forward to the base end side of the fixed frame to store the bicycle is often adopted.

In this type of bicycle parking apparatus, the movable frame rotated downward is moved upward by using an expansion / contraction means such as a spring or a gas cylinder so that the movable frame carrying the bicycle can be easily rotated upward. The device has been devised so as to urge it in the direction of rotation, and further, the lever has been combined with the expansion / contraction means so that the movable frame can be rotated more easily.

There is one described in Japanese Patent Publication No. 2539316.
In this bicycle parking apparatus, as shown in FIGS. 5 and 6, a horizontal fixed frame 51 is provided at its tip with a roller 53 serving as a fulcrum of rotation of the movable frame 52, and the expansion / contraction means 54 and 2 are provided.
The movable frame 52, the front end portion of which is connected to the moving carriage 56 via the two levers 55a and 55b, is urged in the direction of upward rotation by the extension force of the expansion / contraction means 54.

The movable carriage 56 has a pair of front and rear wheels 58 guided by guide rails 57 provided on the fixed frame 51, and is movable along the fixed frame 51. A moving roller 59 is attached to the tip of the lever 55b to which the movable frame 52 is connected. This moving roller 59 fits into another guide rail (not shown) provided on the fixed frame 51 when the movable frame 52 is horizontally rotated, and the moving carriage 5 is moved.
The front end of the movable frame 52, which moves forward and backward along the fixed frame 51 together with 6, is attached to each wheel 58 of the moving carriage 56.
Will guide you in front of you. The guide rail of the moving roller 59 is opened upward in front of the rear end of the guide rail 57 for the moving carriage 56, and the moving roller 59 is released upward from the guide rail as the movable frame 52 rotates. It is like this.

[0006]

A bicycle parking apparatus for assisting the rotation of a movable frame by combining the above-described conventional expansion and contraction means and a lever is a fixed frame, a guide rail for a movable carriage, and a front end portion of the movable frame. Since it is necessary to separately provide the guide rails, it takes a lot of time and labor to process the two guide rails and ensure their parallelism, and there is a problem that the design becomes complicated.

Therefore, an object of the present invention is to enable the front end of the movable frame of the bicycle parking apparatus and the movable carriage connected to the movable frame to be guided by the same guide rail.

[0008]

In order to solve the above-mentioned problems, the present invention provides a fixed frame supported at a predetermined height position from a floor surface with its tip substantially horizontal, and a fixed frame. A movable carriage that has wheels guided by a guide rail and is movable along a fixed frame, and a movable bicycle that moves forward and backward along the fixed frame along with the movable carriage to park a bicycle. And a movable frame, the front end portion of which is connected to the movable carriage via an expansion / contraction means and a lever, and when the movable frame is retracted toward the distal end side of the fixed frame, a fulcrum member provided at the distal end of the fixed frame. In the bicycle-parking device that is rotated downward about a fulcrum, and the movable frame that is rotated downward is urged by the expanding and contracting means and the lever in a direction that rotates upward, the front end portion of the movable frame. , Fitted with wheels at rear side than the connecting portion between the lever by the wheel the guide rail,
A configuration is adopted in which the guide is provided behind the wheels of the moving carriage.

That is, a wheel is attached to the front end of the movable frame on the rear side of the connecting portion with the lever so that the wheel is guided along the fixed frame on the rear side of the wheel of the moving carriage. This allows both wheels to be guided by the same guide rail. In other words, the wheels at the front end of the movable frame need to be released upward from the guide rails as the movable frame rotates, so when the wheels are guided to the fixed frame in front of the wheels of the moving carriage, the same guide rails are used. Can not be used.

A wheel mounted on the front end of the movable frame is locked by a fulcrum member provided at the tip of the fixed frame when the movable frame is rotated downward, so that the movable frame is rotated. It is possible to reduce the number of parts by eliminating the need for a separate positioning member during movement.
