Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a two-tier multi-level parking system, and more particularly to a fall prevention mechanism for an upper parking platform of the two-tier multi-level parking system.

This conventionally known type of two-stage multilevel parking system is
Usually, a mechanism for lifting and lowering the hydraulic cylinder device for raising and lowering the upper parking platform and a lifting guide mechanism having a pillar structure are arranged in a pair on the left and right near the central part of the upper parking platform in the longitudinal direction. . Considering that a vehicle is parked on the upper parking platform and an impact load is placed on it, it is desirable to provide a structure that supports the load near the center of gravity of the upper hook parking platform.

However, with this configuration, the following difficulties are pointed out when using the device. mchikame IK, in order to enter the upper parking platform, the upper parking platform is lowered and positioned on the ground surface. The problem is that great care must be taken when entering and exiting vehicles because the pillar structure suddenly protrudes above the upper parking platform.In other words, if an incoming vehicle comes into contact with the pillar structure, both of them will be damaged. This is because repairing both the suspension mechanism and the vehicle would be a huge burden.
0 problem is that when the upper parking platform is raised and stationary in the upper position and the vehicle is moved in and out of the lower parking platform in good condition, the driver's getting on and off of the parked vehicle is obstructed by the round column structure for elevating and descending. There is a point that This is because the placement position of the t-shield structure usually interferes with the opening and closing of the front seat door of the vehicle. We have developed the following new 11-component two-stage multilevel parking system, and have already filed an application as %Gu Sho No. 56-60925. That is, the gist of the invention related to Exit 11 is basically that a drive mechanism for raising and lowering the upper parking platform is disposed at the rearmost part of the parking device, and that the raising and lowering guide mechanism for the upper parking platform is moved by two intersecting legs. It is provided in a scissor shape that opens and closes with the center of the intersection as an axis, and is placed in the rear half of the device so that when the upper parking platform is lowered and closed, the upper protrusion will not interfere with vehicles entering and exiting the lower parking space. Furthermore, when the legs are opened when the vehicle is ascending, the middle portions of both legs in the upper and lower directions move away at the waist to form a necessary gap, making it easier to open and close the front seat door of the vehicle and for the driver to get in and out of the vehicle. Furthermore, the scissor-type lifting guide mechanism of the upper parking platform has been improved so that the upper parking area does not move up and down while maintaining a horizontal state, but the front part gI4 has a slight sway. Dynamic movement occurs in conjunction with lifting and lowering.K
This invention also includes improvements such as making the volume of the parking device more effective in the vertical direction.

In such a two-tiered parking system,
Equipment - special consideration must be given to lightning generation
This is due to the fact that the upper parking platform falls, and this is due to the fact that the hydraulic syringe device, which is commonly used as a drive mechanism, may lose its supporting force due to oil leaks, rupture of piping lines, etc. This is because it is conceivable that the problem could occur, and even in the case of the horizontal format, it can also occur due to a break in the wire, etc.

From this point of view, the present invention provides a two-tiered multilevel parking system that effectively prevents the upper parking platform from falling by assembling a gutter device to the side and +ell elevating guide mechanism. The specific gist of the present invention is to provide a lower fixing structure including a pair of parallel lower frame bodies fixed on a base and arranged along the left and right sides of a parked vehicle, and this lower fixing structure. An upper parking platform that is arranged parallel to the upper position and includes a pair of left and right parallel upper frame bodies corresponding to the lower frame body; Two legs are interposed to connect these at the nine position,
A pair of left and right scissor-type lifting guide mechanisms are provided to guide the lifting and lowering movement of the upper hook parking platform by opening and closing movements of the two legs around the intersection point, and A lifting electric device that is arranged to connect these at the rearmost position in the front and back direction and drives the upper parking platform up and down, and a mechanical hook between one leg of the scissor type lifting guide mechanism and the lower frame body. and a fall prevention device for the upper parking platform, which is provided so that the upper parking platform can be brought together, and the side-tIl lifting guide mechanism has a front pivot connection point between the upper and lower ends of the two legs and the upper and lower frames on the extraction side. The fall prevention device is installed so as to move forward and backward relative to the pivot connection point to allow the opening and closing movement of the two ball legs. Movable fluffle attached to either side of the lower feeder/4
- and a shaft in which either the lower frame body or the legs is fixed to the other and is hooked and engaged with the flap lever. It is in.

The present invention will be explained in detail below with reference to figures rkJK.

Figures 1 and 2 show the configuration of a two-level multilevel parking system to which the opening and closing device of the present invention is applied. In Figure s1, 2 is a part of the lower fixing structure of the multilevel parking system. The lower frame body extends for a certain length from the rear end to the front side along the left and right sides of the vehicle parking position. And this lower fixing structure integrates the left and right lower frame bodies 2 75? A tatami mat connecting member (not shown), a fixing device (not shown) for fixing the lower frame body 2 to the base 1, and a pallet for the lower parking platform to be installed as necessary. At the front ends of the left and right lower frame bodies 20, there is a side-type guide mechanism, which will be described later.One side, a guide that supports the pivot connection point that rotatably supports the lower end of the bow leg so as to be movable in the front and rear directions. Section 3 is provided.

The parking device lower fixing structure is installed in the shape of a rectangle or a rectangular frame fixed with a small thickness on the base plate 1 by a pair of left and right lower frame bodies 2 and a connecting member between them. It will be done. Reference numeral 4 denotes a lifting guide mechanism for the upper parking platform, which is formed by a pair of O-type closing legs 5 and 9 and is made of Nine Sides.The lower end of one of the legs 5 is pivoted to the rear end of the frame 2. connected,
Upper II #A is the left and right upper frame 13 of the upper parking platform 12, which is omitted.
The id portion 14 formed with 4C is movable in the # wave direction,
and are rotatably and pivotally connected. 7.8 is above.
The shaft 8 at the lower end is for pivoting connection, and the shaft 8 at the upper end is guided by a guide section 14 formed in the upper frame of the upper parking platform 12, for example, and is formed in the front-rear direction and moves in the same direction. It's a trap so you can do it.

(9) The lower end of the other leg 9 is pivotally connected to a guide portion 3 formed in the lower frame body 2 of the lower fixing structure so as to be movable in the front and rear direction and rotatable via a shaft 10. The upper end of the rear end is pivotally connected to the rear end of the upper parking platform 12 via a shaft 11. Reference numeral 6 denotes a central axis rotatably connecting the intersecting center points of the pair of legs 5 and 9.

The Sides-type lifting guide mechanism of this example has one-to-zero legs5.
9 are of equal length and are arranged symmetrically about the central axis 6 such that an axis 7.8.1 is the end pivot connection point of each leg 5 and 9.
0 and 11 are always located at the vertices of the rectangle, so that the upper parking platform 12, which is guided up and down, always maintains a parallel relationship with the surface of the base 10. become.

The upper parking lot 12 includes a pair of left and right upper frames 13, a connecting member (not shown) that connects the left and right upper frames 13, and is supported by these upper frames and the connecting members so that the vehicle can be directly parked. It is composed of a knotlet (not shown) that forms a surface.

Reference numeral 16 denotes a hydraulic cylinder device as a drive mechanism for raising and lowering the upper parking platform 12, and in this example, a cylinder cylinder assembly is installed so as to extend upward from the rearmost part of the upper parking platform 12 via a bracket 15. 17, piston rod 1
The lower end of 8 is pivotally connected to the rearmost part of the lower frame body 2 of the lower fixing structure. Further, the piston port and the upper end side of the door 18 are configured to be moved in and out relative to each other by hydraulic pressure. The hydraulic piping of the hydraulic cylinder device 16 is not shown in the figure, but due to the transmission of hydraulic pressure, the cylinder moves upward until the cylinder 17 reaches the point t, and by releasing the hydraulic pressure, the cylinder The diy 17 moves downward. 19. Each of the 20 companies has a single car parked.

When the oil pressure in the cylinder 17 is lowered from the state shown in the figure, the side-type guide mechanism gradually folds in so as to crush the legs 5 and 9, and moves toward the upper parking platform. 12 descends while maintaining a state parallel to the base, reaches the lowest point and stops. Therefore, in this state, vehicles can enter and exit the upper parking platform 12.

Next, when hydraulic pressure is sent to the cylinder 17, the upper parking platform 12 rises while maintaining a parallel state, contrary to the above, and stops when it reaches the highest point, and the hydraulic pressure at that time is maintained. It remains stationary at the highest point position. In this state, vehicles can enter and exit the lower parking space.

Fig. 2 shows a further improvement on the example shown in Fig. 1, in which the upper parking lot always moves up and down while maintaining a parallel relationship with the base, and the front part of the upper parking lot moves up and down slightly as it moves up and down. It is designed to allow vertical (oscillation) movement, thereby reducing the lifting stroke of the upper parking platform that is required to obtain the required height for the lower parking space of the parking device, and at the same time reducing the parking gap. .

In order to achieve such a configuration, the pair of legs of the sideways wrinkle guide mechanism are made to have unequal lengths, and the upper end position of one of the legs, which is pivotally connected to the front and back middle of the upper parking platform so as to be movable in the same direction, is 1st
The rectangular apex position of the nine-sided guide mechanism explained in the figure is slightly shifted from the position of the rectangle. is indicated by adding 100 to the reference numeral, and its explanation will be omitted.

The feature of the example shown in FIG.
The lengths from 06 to the pivot connecting shafts 107 and 110° 111 are the same length, and the length to the pivot connecting shaft 108 is slightly longer.
There are times when people above the 0 Tonaga line are also viewed in a slightly inferior manner.

As mentioned above, based on the examples shown in Figures 1 and 2,
In order to prevent the upper parking platform 12 (or 112) from falling due to failure of the hydraulic cylinder device O as described above, a fall prevention device is installed in the present invention9, and FIG. 3 shows one implementation thereof. An example is shown.

In the same figure, 201 is a nine-bracket fixed to the lower frame body 2.102, the top part 1illK of which is pivotally supported with a seven-bracket 202, and an electromagnetic mechanism 203 is fixed to the rear wall. In the electromagnetic mechanism 203, a rod 205, which is moved in conjunction with a movable iron core 204 that is moved electromagnetically, pivots the hook lever 202 207 times via a link mechanism 206 pivotally attached to the end thereof. It is provided so that it can be rotated.

That is, the link mechanism 206 includes a crank 206 that swings around a pin 208 on the fixed bracket 201, a first link 206b that is connected between the middle part of the crank 206 and the rod 205, and a crank 206a. The second part connected to the tip of the swing and the connection between the 7-piece motherboard 202
When the solenoid 209, which is comprised of a link 2066 and has a built-in electromagnetic mechanism 203, is de-energized, the protrusion of the rod 205 is small (see FIG. 4 (b)), and the hook lever 202 is moved to the position shown in FIG. Let it stand still as shown by the solid line,
When the solenoid 209 is energized, tIK indicates that the movable iron core 20
4 is set so that the solenoid 209 is attracted and causes the rod 205 to protrude greatly, causing the crane A-202 to jump up to the state shown by the chain line of the third factor.

210 is the leg 9 (or 109
) is a link rotatably supported on the lower end side of the shaft 211, and its rotating tip is connected to the lower frame 2 (or 102
) It is designed to slide on the top. A shaft 212, which hooks and engages with the flipper 202, is assembled on the rotating tip side.

With such a configuration, the upper parking platform 12 (also known as the parking lot 112)
When raised by the hydraulic cylinder device 16 (or 116), the side lift guide mechanism rises from the folded state, and the lower end of one leg 9 (also $1109) touches the lower frame 2. (also Fi102) guide part 3 (or 1
03) When the rear part 11KIIIL of the device and the upper parking platform 12 (or 112) reach the highest point while being guided by K, the rear limit point is reached.

In response to such movement, the downgrade prevention device 7, the flaper 202, is moved from the static state shown by the solid line in FIG. 3 to the electromagnetic machine $2.
03tC, stand up in the shape of the chain line 11 in the same figure, and lower the legs 9.
(or 109) reaches the limit position ftK, the electromagnetic mechanism is turned off and the hook lever 202 is connected to the shaft 210 of the link 210.
If the system is returned to the state shown by the solid line in the figure so that it is hooked and engaged, even if the hydraulic cylinder device fails after this, the folding movement of the Sides-type lifting guide mechanism will be as described above. It is mechanically locked by the 7v crepere 9 (or 109) K, and the fall of the upper parking platform 12 (or 112) is effectively prevented.

The electromagnetic mechanism of the fall prevention device operates only when the upper parking platform 1
Hydraulic cylinder device 16 (or 112)
It is practically desirable that the solenoid 209 is automatically turned on and off in conjunction with the expansion and contraction movement of the leg 9 (or 109) or the leg 5 (or 105). Use movable parts such as IT SWITCH.

It would be better to provide a terminal to perform the switching.

In addition, in the examples shown in FIGS. 3 and 4, butterfly, 7, sauce,
A -r near switch 213 is provided at 5 so that the hook engagement with the shaft 212 of 4-202 can be manually operated.

This type of fall prevention device can be similarly applied even when the parking device is mechanical, and in addition to using an electromagnetically actuated type as the fall prevention device itself, It may be a hydraulically operated type that shares the hydraulic source with the hook lever, or the operating mechanism side including the hook lever may be assembled to the leg rather than the lower frame, and the shaft that hooks and engages with the hook lever 4- may be used. You may also fix it to the lower frame evenly.

FIG. 5 shows an example in which the operating mechanism 203' of the hook lever 202' is a hydraulic cover. In this case, the hook lever 202' is normally raised to the solid line position in FIG. 9 by hydraulic action. In addition, in the event of oil leakage, it is moved to the hooking engagement position indicated by am using a spooling force.

It may also be a valve or oil piping that actively creates a negative pressure with an oil flow.

Figure 6 shows leg 9 (or 109) fill 7. The electromagnetic actuating mechanism 215 including the flavor 214 is assembled, and the lower frame 2 (or 102) ill is assembled with the above-mentioned 7. flavor 21
4 shows an example in which a plurality of shafts 216, 216, . According to this format,
It becomes possible to apply the fall prevention function in stages at any position of the lifting height of the upper parking platform 12 (or 112),
Benefits include improved safety during maintenance and inspection work.

As described above, the two-level parking system according to the present invention is equipped with a fall prevention device for the upper parking platform which is suitable for use in cases where the parking system has a side-type lifting guide mechanism. Extremely useful for improving safety in equipment
It can be said that it has a high value.
