Between the front end of the side plate 51 and the front end of the guide rail 56, a downward hook 61 is provided at the rear end of the swing frame 40 and engages with the hook 43. A stopper rod 60 which is long in the front-rear direction and provided with a handle piece 62 which is bent outward and protrudes outward, is pivoted on the outer surface of the side plate 51 in the direction of the arrow in FIG. Mounted freely. The rear end of the stopper rod 60 is supported by a receiving metal 64 provided on the side plate 51, and the rear end is normally received by the receiving metal 64 as shown by a solid line in FIG. 5, and by pressing down the handle piece 62, the rear end is inclined upward as shown by a chain line in FIG. The lip 32 of the movable frame 5 is provided with a guide holding frame 65 for the front wheels of the bicycle, and the front end of the storage frame 5 is provided with a rear wheel receiving frame 66 and a handle frame 67. . The above-mentioned movable frame 5 is arranged such that the rolling rollers 53, 53 at the rear end thereof are connected to the bottom plate 30 of the support frame 3.
The idler rollers 44 of the swinging frame 4 attached to the support frame 3 while being fitted between the
To the flange 52 of the movable frame 5 and the guide rail 56.
And is attached to the support frame 3 so as to be movable in the longitudinal direction (front-back direction) of the support frame 3. The movable frame 5 mounted as described above
Is pushed horizontally toward the rear end of the support frame 3, and the rolling roller 53 and the idle roller 44 roll, as shown in FIG. It reaches the end and enters the storage state. In this case, as shown in FIG. 9, the swing frame 40 is pulled by the winding spring 8 and pressed down by the movable frame 5 so as to be in a lying state.
Then, the hook 61 at the rear end of the stopper rod 60 gets over the engaging piece 43 at the front end of the swing frame 40 and is engaged. Therefore, if the stopper rod 60 does not push down the handle piece 62 downward, the hook piece 61 does not come off from the hook piece 43, and the movable frame 5 is pushed into the support frame 3 in the retracted state (FIGS. 1 and 2). 9). In order to pull out the movable frame 5 from the support frame 3, the handle 62 of the stopper rod 60 is pushed down, and the stopper rod 60 is positioned around the pivot 63 at the position indicated by the chain line in FIGS. 7 and 9. The hook 61 is disengaged from the hook 43 and the movable frame 5 can be pulled forward. Movable frame 5
Drawer, as shown in FIG. 10, the Kakeana 55 of the locking member 54 in the rear portion, Kaketsume 48a protruding from the rear end portion of the swing frame 40 is engaged and free rotation The roller 44 ends at the rear end of the guide 56, and further withdrawal is not performed because the idle roller 44 and the stopper 57 abut against each other, so that the movable frame 5 is prevented from coming out of the support frame 3. At this time, the rolling roller 53 comes out from under the lip 32 of the support frame 3 and reaches the position of the mounting portion 34. The movable frame 5 pulled out is tilted so that its front end is lowered as shown in FIGS. When the movable frame 5 is pulled out, the movable frame 5 and the swing frame 4
Since it is pivotally attached to the support frame 3 via the support shaft 45,
The movable frame 5 is tilted about the support shaft 45, and the swing frame 4 has its rear end engaged with the hook hole 55 and the hook 49, so that the swing shaft 4 follows the tilt of the movable frame 5. It will tilt to the center. As a result, the distance between the support rod 38 of the support frame 3 for fixing both ends of the winding spring 8 and the support rod 47 of the swing frame 4 becomes longer, and the winding spring 8 is extended. Therefore, the tilting of the movable frame 5 is gradually performed by the reaction force due to the extension of the winding spring 8. In practice, it is preferable to set the strength of the winding spring 8 so that the bicycle is tilted gently while the bicycle is mounted on the movable frame 5, or the bicycle is tilted by slightly pushing it down with human power. When the movable frame 5 is tilted, the tilt receiving portion 36 of the support frame 3 and the bottom plate 5 of the movable frame 5 are brought into contact with each other in the final tilting posture. Thereby, the movable frame 5 can be put on and off the bicycle without grounding the front end thereof, so that the installation area of the bicycle parking device can be saved. In order to put the movable frame 5 in the storage position again, first, the front end of the movable frame 5 is raised to a horizontal state. As a result, the swing frame 40 also becomes horizontal, and at this time, the hook 55 of the movable frame 5 and the swing frame 40
Is disengaged from the hook 48a. Therefore,
After that, if the movable frame 5 is pushed in, the movable frame 5 is locked in the stored state as described above. When the movable frame 5 is lifted, a force for reducing the volume of the winding spring 8 acts, so that a small amount of manpower is required for lifting and the work can be performed lightly. As described above, according to the present invention, the movable frame moving in the support frame and the swingable frame which can be disengaged are pivotally connected to the tip of the support frame. And a supporting mechanism that is coupled to the supporting frame by a pull spring, so that the movable frame can be moved by engaging with a rolling roller provided at the tip thereof and an idler roller provided on the swing frame. Since a supporting plate for supporting the movable frame at the time of tilting is provided at the front end of the movable frame, many excellent effects are achieved as follows. (1) When the movable frame is pulled out in a horizontal state, the engaging holes at the ends of the movable frame are engaged with the engaging claws of the swinging frame. The tension spring of the balance mechanism is extended, and by the resistance thereof, it is possible to prevent sudden descent at the time of pulling out and lighten the weight at the time of lifting. (2) Since the balance mechanism consisting of the movable frame and the pulling spring is separated, the drag works only when tilting, which requires a reduction in operating force, and is attached to the movable frame when pushing and pulling out horizontally. The movable frame is moved by the rolling roller and the idler roller attached to the swing frame, so that storage and removal can be performed lightly. (3) Since the supporting frame is provided with a supporting plate for supporting the movable frame when the movable frame is tilted, the front end of the movable frame is pulled out from the ground when the movable frame is pulled out. It can correspond to floating and supporting. (4) Since the structure as a whole is simple and can be manufactured at low cost, and a tension spring is used for the balance mechanism. Less deterioration in function and excellent durability.
