Description

[Detailed description of the invention] The present invention is a cage for mounting a large number of bicycles, which has an entrance/exit at the bottom and has an endless chain stretched by two sprockets arranged above and below at appropriate intervals. The purpose of this invention is to safely, simply, and easily park a large number of bicycles in parallel on the platform of each cage in a vertical circulation type bicycle parking facility in which bicycles are driven in circulation.

Conventionally, in the above-mentioned vertical circulation bicycle parking facility, as a means for parking a large number of bicycles in parallel while avoiding interference between the handlebars of bicycles adjacent to the base of each cage, there has been a method as illustrated in FIG. something is known. That is, in FIG. 1, A is a cage, B is a platform, and low and high bicycle holding devices C and D are juxtaposed alternately at appropriate intervals in a direction perpendicular to the direction of circulation of the cage A. Of these, the low-level bicycle holding device C has a depressed portion _C1 on the front part of the platform B and a pair of front wheel tilting stops made of a curved bar.
C ₂ prevents the front wheels from tipping over and from swinging back and forth. In addition, the high-level bicycle holding device D is a front wheel guide inclined channel material that slopes upward from the middle part of the platform B.
D ₁ and a pair of front wheel locking devices D ₂ which are connected to the rising end of the inclined channel member D ₁ and are made of a curved bar. In this high-level bicycle holding device D, the bicycle front wheel
J ₁ is pushed up along the inclined channel material D ₁ and falls down beyond the upper end of the channel material D ₁ , by means of a stop material D _2a suspended horizontally between the upper end and the pair of front wheel retainers D ₂ . The front wheel J ₁ is prevented from swinging back and forth, and the front wheel J ₁ is supported from the left and right sides by a pair of front wheel locking devices D ₂ to prevent it from falling.

By the way, as a special circumstance of this type of vertical circulation type bicycle parking equipment, due to the acceleration/deceleration of the cage A during circulation movement and the swinging movement when turning upwards and downwards, the front wheel of the bicycle J parked in the high bicycle holding device D may become locked. There is a risk of jumping out of equipment D ₂ . In order to reduce this risk, the above-mentioned head difference Δh can be increased, but if this is done, the slope of the inclined channel material D ₁ will become large and the front wheel J ₁ will not only be pushed up, but also the front wheel J ₁ will be pushed up.
It also becomes difficult to take out.

In view of the above-mentioned circumstances, the present invention suspends a plurality of cages via a suspension member on an endless chain that circulates in the vertical direction, and each cage is arranged in a high-level and a low-level bicycle parking space in the left-right direction perpendicular to the entry direction. In a vertical circulation bicycle parking facility comprising a platform formed in alternating rows and a support hanger whose lower part is fixed to the platform and whose upper part is pivoted to the tip of the suspension member, the platform is entirely It is bent into a multi-stage slope that descends from the entry side toward the front in the entry direction, allowing the front and rear wheels of bicycles to pass through the rear part of the entry side of the high and low bicycle parking spaces in each row.

It bends horizontally forward from the rising end of the right leg and extends in an inverted V-shape that gradually narrows left and right to form a gradually narrowing part P3, and the front end of the front wheel _J1 is fitted into the front end of the gradually narrowing part P3 to form the front wheel. In order to prevent the front wheel J ₁ from moving forward, a U-shaped advancement prevention portion P4 is formed, and the left and right sides of the advancement prevention portion P4 also serve to prevent the front wheel J ₁ from falling.

The bar 10d ₂ has one end fixed to the left side of the front end of the inclined guide member 10b, rises vertically upward, bends at a right angle from the middle and extends forward horizontally, and has the other end fixed to the left inclined part P1. It has the role of guiding the front wheel _J1 from the front end of the inclined guide member 10b to the left inclined portion P1 without coming off the wheel.

Further, the bar 10d ₃ has the lower ends of the left and right legs fixed to the front left and right sides of the front wheel support member 10c and rises upward, so that the bar 10d 3 is at a height position where the front wheel J ₁ can pass between the left and right legs. The intermediate parts of the left and right legs are fixed to the intermediate parts of the bar _10d1 , and together with the left and right parts of the forward movement prevention part P4, they serve to prevent the front wheel _J1 from falling. .

Reference numeral 10e denotes a retreat prevention member made of a single bar curved into a U-shape, and the lower ends of the left and right legs are connected to the front wheel support member 1.
It is fixed to the rear left and right side surfaces of the vehicle 0c, extends rearward with a slight upward slope, and has a U-shaped curved portion at the rear end to form a retreat prevention portion P5 for the front wheel _J1 .

The low bicycle holding device 11 has a low front wheel locking device 1 on the front part of the platform 7 in front of the rear wheel holding device 11a.
1b is fixedly installed. The front wheel locking tool 11b is made of a single rod curved into a U-shape, and has a width suitable for receiving the front wheel _J1 , and fixes the ends of the left and right horizontal legs to the upper surface of the rising portion 7f. It extends horizontally to the rear, rises slightly forward from the middle, and has an inverted U-shaped upper end. However, the above-mentioned left
The right horizontal leg and the rising portion serve to prevent the front wheel _J1 from falling, and the rear surface of the front end rising portion 7f restricts the forward movement of the front wheel _J1 .

Reference numeral 12 denotes an entry/exit entrance formed at the lower part of the rear wall 1a of the building 1, and when the parking cage 6 starts turning at the lower part of the rear row and the support hanger 5 is tilted at an angle of about 30 degrees from the horizontal, the rear horizontal The upper surface of the portion 7a is a protruding floor 12a fixed to the floor F of the entrance 12.
The sprocket 3 is positioned so that it is flush with the sprocket.

Next, a usage example will be explained. As shown in FIGS. 2 and 4, it is assumed that the parking cage 6 is stopped at a predetermined position in front of the entrance 12 with the upper surface of the rear horizontal portion 7a aligned with the protruding floor 12a. From this, the left high bicycle holding device 10 shown in FIG.
When parking the bicycle _J at
Push forward and upward along the . Eventually, the front part of the front wheel _J1 collides with the left side of the gradually narrowing part P3, and the front wheel _J1 moves forward while gradually turning to the right side. Further, when the lower part of the front wheel J ₁ leaves the inclined guide member 10b and rides on the left inclined portion P1 of the bar 10d ₁ , the entire front wheel J ₁ slides to the right and fits into the groove of the front wheel support member 10c.
At this time, the rear wheel _J2 is located at the rear inclined portion 7b, and the rear wheel J2 is located at the rear inclined portion 7b and the front wheel support member 10c.
Bicycle J
moves forward without applying a particularly large force, and the front part of the front wheel _J1 fits into the U-shaped advance prevention part P4 and collides with the part to stop it (see Figures 3, 4, and 6).

Now, the front wheel J ₁ is connected to the forward movement prevention part P4 of the bar 10d ₁ .
And the bar 10d ₃ prevents it from falling and prevents it from moving forward.
The rear wheel _J2 is prevented from moving laterally by the rear wheel holder 10a. During the circulation of the cage 6, even if the cage 6 shakes abnormally and the bicycle J parked on the high-level bicycle holding device 10 moves backward, the front wheel J ₁ will not move as shown by the two-dot chain line in FIG. The rear lower part fits into and collides with the backward blocking member 10e, and the bicycle J is prevented from falling off the platform 7. Furthermore, once the shaking of the cage 6 has subsided, the bicycle J will naturally return to its original state due to the forward downward slope of the rear inclined portion 7b and the front wheel support member 10c.

When parking the bicycle on the low bicycle holding device 11, the front wheel _J1 is passed between the left and right bars of the rear wheel holder 11a and inserted into the low front wheel locking device 11b.
Push it forward until it collides with the front end rising portion 7f.
The front wheel _J1 is now prevented from falling down by the front wheel locking device 11b, and its forward movement is restricted by the front end rising portion 7f. At this time, the rear wheel _J2 is located at the rear inclined portion 7b and is prevented from moving in the lateral direction by the rear wheel holder 11a. In this case, especially since the front wheel _J1 is arranged at the front inclined part 7d having a large inclination angle,
The bicycle J is always given a forward downward force, so that the bicycle J will not move backwards and be thrown off the platform 7 even if the cage 6 shakes. In addition, when parking on this low-level bicycle holding device 11, since the front wheel holding position has an inclined surface that starts from the front in the approach direction, the high-level bicycle holding device 11 is parked first.
Even if a bicycle with a basket is parked in the parking lot, there is no risk of contact between the handle and the basket near the final holding position, and the bicycle can be parked smoothly.

As detailed above, when using the bicycle parking equipment of the present invention, a sufficient height difference is provided between the front wheel holding position and the bicycle parked in the adjacent parking position, and the platform is moved from the vicinity of the entrance to the reference plane at the time of entry. It is sloped downward in the direction of entry, and the front wheel support position in the low-level bicycle parking space is formed at the downwardly sloped tip of this platform, eliminating the risk of bicycles coming into contact with each other when entering and exiting the parking space, and also allowing bicycles to be held at a high level. When parking the device, the front wheel rises along the inclined guide member and is guided by the high front wheel locking device to be transferred to the lateral front wheel support member, where the high front wheel locking device and the backing prevention member are connected to each other. This prevents the front wheel from tipping over and restricts forward/backward movements, so even if the base shakes, there is no risk of the bicycle falling off the wheel or falling off.Also, since the above-mentioned transition is only a lateral shift, this is the first example of conventional The drop of the sliding wheel is very small compared to the front wheel drop Δh shown in Figure 1, and the platform is sloped downward in the forward direction of entry, and the front wheel support position in the low bicycle parking space is set from the reference plane at the time of entry. By lowering the height, the height of the inclined guide member can be kept to the minimum necessary level, and the human power required to lift the front wheel can be kept to a minimum.
