[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIGS. 1 to 6 show a bicycle parking device provided with a device according to an embodiment of the present invention, and FIGS. 7 and 8 show another embodiment.

First, a first embodiment of the present invention will be described. As a whole, the bicycle parking device includes a column 1 standing on the ground, a storage frame 6 fixed to a lower portion of the column 1, a support frame 2 mounted horizontally on an upper end of the column 1, and A movable frame 3 is attached to the supporting frame 2 so as to be able to travel in the front-rear direction along with the frame 2 and is tiltable with respect to the supporting frame 2. It consists of.

The support frame 2 is formed to be long in the front and back by a channel steel with a lip having a cross section whose upper side is opened, and has a front end portion having a cross section (U-shape) having a required length in the front and rear direction. A mounting portion 21 for accommodating a swing frame 4 described later is provided. The mounting portion 21 is provided with a long front and rear spring through hole 22 and a spring support rod 23 on a bottom plate thereof, and a shaft hole 24 at an upper portion of a front end portion of the side plate. At the front end of the side plate of the support frame 2, there are provided hooking pieces 25, 25 protruding inward.

The oscillating frame 4 is formed of a cross-sectional channel steel having a length and a width that can be accommodated in the mounting portion 21 of the support frame 2. 41 is provided so that the support shaft 42 protrudes outward. In addition, the bottom plate is provided with a spring through hole 43 which is long in the front and rear direction, and a spring support rod 44 is provided at a rear end thereof. A claw plate 45 is provided.

The swing frame 4 is inserted into the shaft hole 24 of the mounting portion 21 of the support frame 2 by inserting the support shaft 42 into the mounting portion 21 so as to be swingable about the support shaft 42 in the mounting portion 21. The winding spring 7 is stretched over the support rod 44 of the swing frame 4 and the support rod 23 of the support frame 2. As a result, the swing frame 4 is moved from the contracted down position of the winding spring 7 in the mounting portion 21 as shown in FIG. It can swing to a standing position.

The movable frame 3 is formed sufficiently longer than the support frame 2 by a hat-shaped steel member having an open upper side in a width capable of moving in the swing frame 4, and a lower portion of the rear end portion includes the support frame 2. Rollers 31, 31 are provided between the bottom plate and the lip 26, and a hook hole 32 is provided for engaging and disengaging the hook claw plate 45 of the swing frame 4. On the outer surface of both side plates 33 of the movable frame 3, a guide rail 35 is provided between the flange 34 and the bottom plate from the front to the rear in parallel with the bottom plate, and the rear end thereof is upward. It is bent to form a stopper 36. A guide groove 37 is formed between the guide rail 35 and the flange 34, into which the floating roller 41 provided on the swing frame 4 is fitted.

A downward hook is provided between the front end of the side plate 33 of the movable frame 3 and the front end of the guide rail 35 to engage with a hook 25 provided at the rear end of the support frame 2 at the front end. A stopper rod 5 having a piece 50 and extending in the front-rear direction is attached to the outer surface of the side plate 33 at a position closer to the front than the center thereof by a pivot 51 so as to be rotatable in the direction of the arrow in FIG.

The stopper rod 5 is received at its rear end by a receiver 52 provided on the side plate 33, and is always substantially parallel to the movable frame 3. By pressing down, as shown by the chain line in FIG. 5, the rear end is brought into an inclined state lifted upward. Therefore, when the movable frame 3 engaged with the support frame 2 and the swing frame 4 is pushed toward the rear end of the support frame 2, the hook 50 at the rear end of the stopper rod 5 After hitting the hooking piece 25 at the front end, it rises and is hooked on the hooking piece 25. As a result, the hook 50 tends to always fall, so that the hooked state is maintained, and if the hand piece 53 is pressed down, the hook 50 is lifted and deviated from the hook 25.

In FIG. 1, reference numeral 8 denotes a guide and a support for the front wheels of the bicycle provided on the movable frame 3, reference numeral 9 denotes a receiving frame for the rear wheels of the bicycle, and reference numeral 10 denotes a handle frame.

The movable frame 3 has a front-end rolling roller 31 fitted between the bottom plate of the support frame 2 and the lip 26, and a free-running roller of the swing frame 4 attached to the support frame 2. 41 is fitted in the guide groove 37 of the movable frame 3 and is attached to the support frame so as to be movable in the longitudinal direction (front-back direction).

When the movable frame 3 attached as described above is pushed horizontally toward the rear end of the support frame 2 in a horizontal state, the rolling rollers 31 and the idle rollers 41 roll, as shown in FIG. Then, the rear end of the movable frame 3 reaches the rear end of the support frame 3 and enters the retracted state. In this case, as shown in FIG. 5, the swinging frame 4 is pulled by the winding spring 7 and is pressed down by the movable frame 3 to be in a lying state. Then, the hook 50 at the rear end of the stopper rod 5 gets over the engaging piece 25 at the front end of the support frame 2 and is engaged. Therefore, unless the stopper rod 5 pushes down the hand piece 53 downward, the hook piece 50 does not come off from the hooking piece 25, and the movable frame 3 is pushed into the support frame 2 (see FIG. 1, see FIG. 5).

In order to pull out the movable frame 3 from the support frame 2, if the hand piece 53 of the stopper rod 5 is pushed down, it swings around the pivot 51 of the stopper rod 5 to the position shown by the chain line in FIG. As a result, the hook 50 is separated from the hook 25, and the movable frame 3 can be pulled forward. When the movable frame 3 is pulled out, as shown in FIG. 6, a hook claw plate 45 projecting from the rear end of the swing frame 4 is engaged with the hook hole 32 at the front end, and the idle roller 41 ends at the rear end of the guide groove 37, and further drawing is not performed because the idler roller 41 and the stopper 36 abut against each other, so that the movable frame 3 is prevented from coming out of the support frame 2. Further, at this time, the rolling roller 31 escapes from under the lip 26 of the support frame 2 and reaches the position of the mounting portion 21.

The drawn-out movable frame 3 is tilted so that its front end is lowered as shown in FIGS. When the movable frame 3 is pulled out, the movable frame 3 and the swing frame 4 are pivotally attached to the support frame 2 via the support shaft 42, so that the movable frame 3 tilts around the support shaft 42 and swings. Since the rear end of the frame 4 is engaged with the hook hole 32 and the hook claw plate 45, the frame 4 tilts about the support shaft 42 in accordance with the tilt of the movable frame 3. As a result, the distance between the stop rod 23 of the support frame 3 for fixing both ends of the winding spring 7 and the support rod 44 of the swinging frame 4 becomes longer, and the winding spring 7 is extended. Therefore, the tilting of the movable frame 3 is slowly performed by the reaction force due to the extension of the winding spring 7.

In order to put the movable frame 3 in the storage position again, first, the front part of the movable frame 3 is lifted to a horizontal state. As a result, the front portion of the swing frame 3 is lifted to be in a horizontal state. As a result, the swing frame 4 is also in a horizontal state. At this time, the engagement between the hook hole 32 of the movable frame 3 and the hook claw plate 45 of the swing frame 4 is released. Then, as described above, the rear end of the movable frame 3 advances to the front end of the support frame 2, the hook 50 of the stopper rod 5 is hooked on the hook 25 of the support frame 2, and the movable frame 3 Will be locked in the retracted state.

Next, a second embodiment of the present invention will be described with reference to FIGS. This embodiment differs from the previous embodiment in a part of the means for locking the movable frame 3 in the storage position. That is, the engaging piece that is the counterpart of the hook 50 of the stopper rod 5 is replaced with the front end of the support frame 2, and an inwardly projecting engaging piece 46 is provided at the front end of the swing frame 4. .

The location where the hooking pieces 25 and 46 are provided does not cause any particular difference in the locking function between the front end of the support frame 2 and the front end of the swinging frame 4. Good. In the second embodiment, other parts are the same as those in the first embodiment, and the description thereof is omitted. Further, in the case of the first embodiment, the present invention can be applied to a structure having no swing frame 4.
