Description

[Detailed description of the invention] [Industrial application field] This invention is a rotating wheel hanging type that allows multiple bicycles to be hung in the air and parked, and can be retrieved easily with a light manual operation. This invention relates to a bicycle parking device.

[Conventional technology and technical issues to be solved]

As is well known, various bicycle parking devices have been proposed today, but most of them are limited to ways to organize and store bicycles in a designated area in a space-saving manner. Product of minimum required occupied area (w) and number of storage units (u) (W = w x u)
In other words, it is impossible to reduce the storage area, and in cities where land prices are high, it is impossible to fully meet social demands.

For this reason, in order to make effective use of narrow spaces, a Ferris wheel-type "bicycle parking device" was proposed, for example, as disclosed in Utility Model Application Publication No. 60-40762, in which bicycles are parked in a multi-dimensional manner. However, the system is mechanically driven by an electric motor to store, move, and take out the bicycles, making it cumbersome to operate. It has been reported that the bicycles are mixedly stored in the bicycle frame (frame), making it difficult to find the desired bicycle when removing the bicycle, and this problem has not yet been found to be an effective solution.

This invention was developed in view of the above-mentioned situation with conventional bicycle parking devices for storing bicycles. Our technical problem is to provide a practical rotating wheel hanging type bicycle parking device that can quickly find the desired bicycle and take it out easily, safely, and quickly by hand-cranking. It is something to do.

[Means adopted to solve the problem]

The means adopted by the present inventor to solve the above technical problem will be explained with reference to the attached drawings.
It is as follows.

That is, in the present invention, a bicycle parking wheel 3 is rotatably disposed on a stand frame 1 erected on the ground by a rotating shaft 2 supported in a horizontal direction, and bicycle parking wheels 3 are distributed at equal angles on this bicycle parking wheel 3. A plurality of chassis hangers 4, 4, . The input shaft 52 of this gear transmission mechanism section 5 has a hand crank 5.
The above-mentioned technical problem can be solved by connecting the bicycle parking wheel 3 to the bicycle parking wheel 3 and rotating the handwheel 51 so that the bicycle parking wheel 3 can be rotated freely in the circumferential direction. We have achieved a satisfactory rotating wheel hanging type bicycle parking device.

〔Example〕

Hereinafter, the present invention will be explained in more detail based on embodiments shown in the accompanying drawings.

FIG. 1 is a perspective explanatory view of a bicycle parking device according to an embodiment of the present invention. In the figure, what is indicated by reference numeral 1 is a stand frame having a support section 12 that stands upright on the ground, and includes a bottom plate 11 that is fixed to a concrete foundation (not shown) via anchor bolts, and rib plates 13, 13 on this bottom plate 11. It is fixed upright via...

In this embodiment, a rotating shaft 2 is attached to the upper end of the support column 12.
The center of the bicycle is supported, and ring-shaped bicycle parking wheels 3, 3 are counterbalanced to each other via four ribs 31 at both left and right ends. On both bicycle parking wheels 3, there are a plurality of chassis hangers 4 (4 in the drawing) arranged at equal angular intervals for hanging the bicycle B.
Bicycles B, B...
is constructed so that its wheels are positioned downward due to its own weight. Specifically, as shown in FIG. 2, the handle and saddle of the bicycle are hung on both ends of the chassis hanger 4, which is pivoted so as to balance the center of gravity of the bicycle B. ,b,
Alternatively, as shown in FIG. 3, a mounting frame 41' may be provided at the bottom of a triangular chassis hanger 4' whose apex is pivoted. , this mounting frame 41' has a sixth
The front and rear wheels of bicycle B may be suspended in a drop-down manner as shown in figures a, b, and c. In short, it is important to suspend and support the bicycle in a substantially horizontally balanced manner.

Reference numeral 51 designates a hand-cranked handle, which is arranged along one side of the bicycle parking wheel 3. The hand-cranked handle 21 and the rotating shaft 2 of the bicycle parking wheel 3 are linked as follows. That is, as shown in FIG. 4, a sleeve member is fitted onto the outer periphery of the rotating shaft 2. As shown in FIG. This sleeve member constitutes an input shaft 52 of the gear transmission mechanism section 5, and is connected to the hand-cranked handle 51 via a spoke rod. The gear transmission mechanism section 5 in this embodiment includes a sleeve member constituting the input shaft 52; a first screw gear 52a fixed to the input shaft 52; and a first screw gear 52a attached to the transmission shaft 53 and meshing with the first screw gear 52a. a second screw gear 53a; a first worm gear 53b mounted on the transmission shaft 53 coaxially with the second screw gear 53a; meshing with the first worm gear 53b, and itself perpendicular to the transmission shaft 53; a second worm gear 54a mounted on a second transmission shaft 54 disposed in the direction;
It consists of a pinion 54b attached to the transmission shaft 54; and a gear 55 that meshes with the pinion 54b and is itself attached to the rotating shaft 2 of the bicycle parking wheel 3.

Therefore, when the input shaft 52 is manually rotated in the forward and reverse directions, the input shaft 52 rotates to the first position.
The screw gear 52a is rotated, and the rotation is transmitted to the second screw gear 53a, which rotates the coaxial first worm gear 53b. When the first worm gear 53b is rotated, the second worm gear 54a meshing therewith is rotated, and the rotation is transmitted to the coaxial pinion 54b, causing the gear 55 to rotate. When the gear 55 is rotated, the rotating shaft 2 and the bicycle parking wheel 3 are also rotated. In this way, the rotational force of the hand-cranked handle 51 is increased and transmitted to the rotating shaft via the gear transmission mechanism 5, making it possible to easily rotate the bicycle parking wheel 3, and at the same time, the bicycle B is placed on the bicycle parking wheel 3. Even if the bicycle is not hung evenly and its weight is unevenly distributed, the bicycle parking wheel 3 is prevented from being reversed due to the weight of the unevenly distributed bicycle.

〔how to use〕

When the bicycle 2 is to be parked in the bicycle parking device of this embodiment, the bicycle parking wheel 3 is first rotated using the hand crank 51 to move the empty chassis hanger 4 to the lowest position. Therefore, in the case of the hanger shown in Fig. 2, as shown in Figs. If the saddle of bicycle B is hooked to the other end of the chassis hanger 4 as shown in (b),
Thereby, the bicycle B can be suspended above the ground surface in a substantially horizontally balanced manner (FIG. 3(c)).

On the other hand, in a modified embodiment of the present invention using a chassis hanger 4' as shown in FIG. 3, as shown in FIGS. When the rear wheel is placed on the mounting frame 41' (a and b in the same figure) and the rear wheel is also placed on the mounting frame 41', it is suspended in a substantially horizontal balance with both tires sandwiched (c in the same figure). ).

[Effects of this invention]

As explained above, according to the present invention, a plurality of bicycles are suspended and arranged around the periphery of the bicycle parking foil, so that a large number of bicycles can be parked in an orderly manner in a small space.

In addition, with the bicycle parking device of the present invention, since the bicycle is suspended by the chassis hanger, it is easy to park the bicycle, and it is also possible to find the bicycle to be taken out at a glance, making it extremely easy to take out the bicycle. be.

Furthermore, even if the weight of the bicycle is unevenly distributed, the bicycle parking device of this invention prevents the bicycle parking wheel from reversing due to the action of the gear transmission mechanism, making it safe to operate and extremely easy to handle. be.

In this way, the present invention makes it possible to save space and make effective use of land even in large cities where land prices are high, and to effectively deal with the problem of bicycle parking, which has traditionally been considered a difficult problem. Its practical merits are extremely large, such as its simple structure and no need for power, making it possible to provide it at low cost.
