Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a two-stage bicycle parking device that performs parking using only human power.

Recently, various bicycle parking devices have been devised to prevent bicycles from being left unattended near stations, supermarkets, etc.

However, the appropriate form of equipment will differ depending on various conditions such as the state of available parking space, the limit of capital investment capacity, and the type of user group. The present invention relates to a simple bicycle parking device that aims to provide an efficient bicycle parking device that is highly efficient and does not use any power.

In other words, the trestle forms a two-level parking space, with the lower level allowing normal surface parking.The bicycle can be parked on the upper level of each of the lower level parking areas, and the bicycle can be parked on the ground while being placed on the parking member. It is capable of being raised and lowered by only human power, and is characterized by the use of spring force to assist in raising and lowering, and by the use of a double pulley mechanism for ease of operation.

The biasing force can be adjusted by adjusting the movement of the nuts 12a and 12'a.

Reference numeral 15 denotes a parking member for parking the bicycle J in the upper parking space U, which includes a U-shaped parking frame 16 that is elongated and has an upper opening and has horizontal protrusions 16a and 16b formed at the upper ends of both left and right sides; A bottom plate frame 17 fitted inside the bottom of the parking frame 16 for the purpose of reinforcement, and a front wheel J of a bicycle J, respectively.

Provides supplementary support.

Reference numeral 25 denotes a rope for lifting and lowering the parking member 15, one end of which is fixed to the lower left end of the rear end plate 16c of the parking frame 16, and a relay pulley 2 that is pivotally supported inside the left side support plate 7 of the support guide member 6.
6, the lower groove of the relay pulley 27 that is pivotally supported on the center bottom of the fixed frame 5, the upper pulley 28a of the fixed pulley group 28 that is pivoted on the front bottom of the fixed frame 5, and the upper and lower mountings. Plate 29a・

It is fixed to a pin 31 fixed between the front parts of 29b.

Reference numeral 32 denotes two tension springs stretched between the support shaft 10 and two pins 33 fixed between the rear portions of the mounting plates 29a and 29b, which keep the movable pulley 30 always rearward. The rope 25 and the fixed pulley group 2 are
The parking member 15 is pulled forward via 8 or the like.

Reference numeral 34 denotes a rear stopper plate fixed to the rear lower surface of the parking frame 16, which abuts against the rear ends of the support plates 7 and 7' to prevent the parking member 15 from moving further forward.

Reference numeral 35 denotes a front stopper plate attached between the upper surfaces of the horizontal protrusions 16a and 16b at the front end of the parking frame 16, which collides with the front ends of the surface support plates 7 and 7' and prevents the parking member 15 from being pulled any further. This prevents the vehicle from descending and retreating.

Reference numerals 36 and 36' denote two types of locking members, low and high, for the front axle J1 for parking the bicycle J directly on the ground floor 3 of the lower parking space, and wheel fitting frames 36a and 36' each having a U-shaped cross section. The front end side of a is provided on the side of the horizontal side 2a, and the former is the angle member 3 provided on the side of the horizontal side 2a.
7, the latter is fixed in parallel at the same height as the horizontal side 2a, and the latter is parallel to the horizontal side 2'a and tilted slightly upward by an angle member 37' that connects the vertical side of the support 2' and the horizontal side 2'a. Further, anti-falling/stopper members 36b and 36'b are provided at the upper part of each of the parts.

In use, first, as shown in FIG. 2, the parking member 15 is housed horizontally within the fixed frame 5 (at this time, the position of the support shaft 10 is set at X in FIG.

Then, the pivot points of the hook-shaped arms 14, 14' are at the position of
The user is receiving a counterclockwise moment (=fxd1) about the support shaft 10 as a fulcrum due to the force f of
9 and pulls out the parking member 15 backwards (toward the user) against the spring force of the tension spring 32. When the parking member 15 is pulled out from the support rollers 24 and 24' as well as the support guide member 6 support rollers 20, 21, 20', 2
1' and guide rollers 22, 23, 22', and 23'.

The pulling force in this case is reduced to 1/2 by the double pulley action of the fixed pulley group 28 and the movable pulley 30.

When the parking member 15 is moved slightly backward and then pulled down, the parking member 15 rotates clockwise (in FIG. 8) around the support shaft 10 integrally with the support guide member 6, and the support is removed. It separates upward from the rollers 24 and 24'.

Along with this rotation, the pivot points of the front and rear hook-shaped arms 14 and 14' move from Xl toward the dead center X2, and the amount of eccentricity gradually decreases from dl toward O, so that the support guide member 6 The counterclockwise moment exerted by becomes gradually smaller.

After the rotation, the weight of the parking member 15 acts greatly together with the decrease of the moment, and the parking member 15 rotates downward together with the support guide member 6 just by a light force applied by the user. While moving backward, pull out the parking member 15 fully as shown by the solid line in FIG.
When the parking frame 16 collides with the support plates 7 and 7', the rear lower end of the parking frame 16 is brought into contact with the ground floor 3 as shown by the two-dot chain line in the figure.

In this state, the pivot points of the hook-shaped arms 14 and 14' have passed the dead center X2 and reached the X3 position on the opposite side, so the support guide member 6 is receiving a compression spring force f, but there is a slight force in the opposite direction. It receives a slight clockwise moment corresponding to the eccentricity d2 and is locked in that position.

Therefore, even if the user releases the handle 19, there is no danger that the parking member 15 will jump upwards.

Thus, the user mounts the bicycle J on the parking member 15 in the locked state shown by the two-dot chain line in FIG. 8, and then grasps the handle 19 and lifts it slightly upward.

At this time, contrary to the above-mentioned lowering operation, as the parking member 15 and the support guide member 6 integrally rotate upward, the pivot points of the hook-shaped arms 14 and 14' move from X3 to the dead center. As the support guide member 6 moves beyond X2 toward Xl, the counterclockwise moment received by the support guide member 6 gradually increases, and this force is applied to the tension spring 32, so that the parking member 15 can be supported and guided by just applying a light force. It is pulled back forward within the fixed frame 5 while being guided by the member 6.

In the above explanation, the parking spaces are arranged in multiple rows, but the object of the present invention can also be achieved even if the support pillar, fixed frame, support guide member, parking member, etc. are used as one unit for parking only two vehicles, one above the other. Also, if a cushioning material such as rubber is added to the rear end ground contact part of the parking member, it will be safe and noise-free.

As detailed above, according to the present invention, it is possible to park in two levels, upper and lower, with simple equipment, and when unloading to the ground, the support and guide member The reduction in the forward moment of the vehicle and the operating force combined with the weight of the parking component automatically locks the parking component after it is possible to lower it, and also prevents the parking component from entering the upper deck. In addition, by increasing the forward moment of the lifting spring force and the support guide member, a safe and smooth loading operation is possible with a small amount of human power.
The fixed frame, the support guide member, and the parking member form one unit, and the number of parking spaces can be easily increased by increasing the number of units, and it is extremely inexpensive because it is operated entirely by human power without requiring any prime mover. Not only can it be used as a safe device, but it requires only a small amount of operating force, so it can be handled safely by women and children, and there is no fear of breakdowns.
