Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a hoistway in a bicycle parking lot.

Traditionally, equipment for lifting bicycles into bicycle parking lots involves lifting the bicycle up and down a gentle slope while manually pushing the bicycle, elevator equipment that lifts and lowers both people and bicycles, and lifting equipment that lifts and lowers bicycles while riding or supporting them with their hands on a conveyor. Various other things have been announced.

Among these, for example, as a conveyor type,
What is disclosed in Publication No. 173493 is that a belt conveyor is provided on the side of a pedestrian staircase along the inclination of the stairs and is equipped with a protrusion on the top surface to prevent bicycles from tripping. The bicycle is transported by placing the front and rear wheels on the conveyor, but during transport, the user must hold the bicycle upright by holding the handlebars or saddle, and must climb up and down at the same speed as the conveyor.

Therefore, elderly people, children, or users who are inexperienced with this type of equipment may become distracted by supporting their bicycles and may stumble when going up or down the stairs, which poses a safety problem.

In view of the above-mentioned circumstances, the present invention provides a belt conveyor consisting of a pair of left and right endless belts spaced apart appropriately in a concave ramp provided on the side of the stairs along the inclination of the stairs, and furthermore, A concave guide groove is laid down between the belts, almost parallel to the upper track of the endless belt, and the front and rear wheels of the bicycle are fitted into the guide groove, and both pedals can be placed on each endless belt. The purpose of the present invention is to provide a hoistway in a bicycle parking lot for the purpose of safely raising and lowering bicycles without any human effort and while keeping bicycles in an upright position.

In detail based on the embodiment shown in the figure, 1 is the upper floor 2
4 is a staircase provided between the stairs 1 and the lower floor 3, and 4 is a guide groove for descending bicycles in which a fixed floor with an appropriate depth and slope is integrally formed on one side of the staircase 1 by an inner guide wall 5 and an outer guide wall 6. , 7 is a concave ramp having an appropriate depth and slope that connects the pits 2a and 3a provided on the upper and lower floors 2 and 3 on the other side of the stairs 1,
Belt conveyor 8 for up-bound bicycles is installed.

The belt conveyor 8 is connected to the pits 2a and 3.
A set of two pulleys 9a, 9b; 1
0a, 10b are freely rotatably supported on the left and right by the distance between the left and right pedals Ja, Jb of a general bicycle J, and a pair of left and right Endless belt 1
The endless belts 11, 12 are always kept under tension by guide pulleys 13a, 13b, 14a, 14b supported at appropriate positions on the ramp 7, and return rollers 15a, 15b. Further, the surfaces of the endless belts 11 and 12 are roughened to have sufficient frictional force.

Reference numeral 16 denotes a rotating shaft supported in the pit 2a via suitable bearings, and left and right 1 fixed to the rotating shaft 16
The pair of small gears 17a, 17b are connected to the pulleys 9a, 9.
They are meshed with large gears 18a and 18b which are fixed coaxially with the pulley on the outside of each of the pulleys.

Reference numeral 19 denotes a motor with a brake connected to the rotary shaft 16 via a reducer 20 in the pit 2a, and the rotary shaft 16 is rotated by the drive of the motor, and small gears 17a and 17b having the same number of teeth and large gears 17a and 17b having the same number of teeth are driven by the motor. The endless belts 11 and 12 can be circulated in the same direction and at the same speed via gears 18a and 18b and pulleys 9a and 9b having the same diameter.

21a and 21b are the endless belts 1, respectively.
1 and 12 guide plates, each endless belt 1
1, 12 along the upper orbits of the pits 2a, 3.
a and the inner wall of the ramp 7.

Reference numeral 22 denotes a guide groove with a concave cross section for the bicycle J wheel disposed below the belt conveyor 8. The lower end starts at the bicycle J entry section 3b of the lower floor 3, passes through the pit 3a, and connects the left and right endless belts. 11, 12, extends parallel to the upper track of the endless belts 11, 12, and extends downward from the upper track of the left and right endless belts in a direction perpendicular to the track at the height of the rotation axis of a typical bicycle pedal. The bottom part is located at a lower position by a height slightly higher than that of the bicycle, and the width is slightly wider than the width of a typical bicycle tire, so that when both the left and right pedals of a typical bicycle are placed on the endless belt, the front and rear wheels are engaged appropriately. It has a U-shaped cross section with side walls that are tall enough to fit together, and passes through the pit 2a to become the bicycle J exit section 2b, which is connected to the upper floor 2. Further, the openings at both ends of the guide groove 22 are gradually widened in order to facilitate the entry and exit of the bicycle J.

Therefore, when using the main hoistway, the motor 19
is driven to operate the belt conveyor 8 in the upward direction. However, this rising speed shall be slightly slower than the walking speed of an ordinary person.

User M who wants to get off from the upper floor 2 should put the front and rear wheels Jc and Jd of bicycle J into the guide groove 4 and descend stairs 1 while supporting bicycle J (see Figure 1). .

Further, the user M who wants to go up from the lower floor 3 to the upper floor 2 puts the front and rear wheels Jc, Jd of the bicycle J into the guide groove 22 at the entry section 3b. Then, while supporting Bicycle J, I push it towards Stairs 1.
First, one pedal (for example, Jb) is connected to the endless belt 1.
2 (see Figure 4). When the bicycle J is further pushed forward a little, the guide groove 22 is aligned with the endless belt 1.
1 and 12, the pedal Jb is pushed upward,
Finally, the other pedal Ja also hits the endless belt 11 (the state shown in FIG. 3).

After that, even if the user M lets go of the bicycle J, both pedals Ja and Jb are supported on the endless belts 11 and 12, and the front and rear wheels Jc and Jb are in the guide groove 22, so that the bicycle is J is kept upright without falling down. At this time, if the center of gravity of bicycle J is behind the axes of pedals Ja and Jb, the rear wheel
Jd rides on the bottom of the guide groove 22, and the front wheel Jc floats up.

In this way, since most of the total weight of the bicycle J is borne by the endless belts 11 and 12 via both pedals Ja and Jb, the endless belts 11 and 12 are
2 rises smoothly. Therefore,
The user leaves Bicycle J and goes up the stairs to the upper floor 2.
Wait for Bicycle J to arrive.

When the bicycle J reaches the upper floor 2, the user M grasps the handlebars of the bicycle J and moves it forward. Eventually, both pedals Ja and Jb separate from the endless belts 11 and 12, so the user M leaves the bicycle J from the exit section 2b.

In the above-mentioned embodiment, a belt conveyor was installed only for bicycles going up, but a belt conveyor having the same structure as this can also be installed in the downhill bicycle path on the opposite side and used for bicycles going down.

Further, if free rollers are provided at appropriate pitches on the guide plates 21a and 21b, even smoother circulation of the endless belt can be achieved.

Further, the stairs in the above-mentioned embodiments are not essential, and a plurality of rows for ascending and descending may be provided in parallel for unmanned transportation.

As detailed above, when using the hoistway of the present invention, the user simply inserts the front and rear wheels of the bicycle into the concave guide grooves and pushes them forward to near the belt conveyor, and both pedals are automatically placed on the endless belt. After that, the bicycle can be raised and lowered without any need for the user to support the bicycle while remaining upright, making it safe and easy for the elderly and children to use.
