Abstract

PURPOSE:To provide a double-deck vertical parking apparatus in support board- lifting structure capable of storing two cars in a space for one car with less dead space. CONSTITUTION:A support board 11 is held at the uppermost position A of lifting with its entrance/exit port side 13 kept higher a little by operation of a link 73 that is interlocked with a driven link 61. Since a wheel-stop plate 47 is provided to the innermost part 14 of the support board, a car 15 can be supported in stability. When lowered to the lowermost position B, the support board 11 is placed in sloped position with its entrance/exit port side 13 touching a plane with which a base frame is in contact. An incoming car is brought by self-traveling onto the sloped surface and is mounted on the support board 11 under the sloped state. When a lifting board member 51 is lifted from the above-mentioned position and is brought to the uppermost position A, a space for storing another car 125 can be provided beneath the lifting board member 51.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-story parking system for passenger cars, and more specifically, by raising one vehicle, securing two land for expropriation on the site for one vehicle and landing the land. The present invention relates to a two-stage type three-dimensional parking device that effectively uses a vehicle.

[0002]

2. Description of the Related Art In recent years, the demand for parking lots has increased rapidly with the spread of automobiles, but it is becoming difficult to secure parking lots due to lack of land and soaring land prices. Therefore,
There is a great demand for a multi-storey parking lot that can effectively use a small amount of land with a simple structure, and various structures have been constructed. In particular, since the two-stage type multi-level parking device has a simple structure, it is advantageous for use of the upper space in an existing parking lot and installation in a residential area.

Generally, in a two-tiered multi-level parking apparatus, first, a shelf board in which a first vehicle is loaded and housed by itself is raised horizontally, and a space for a second vehicle to be loaded is provided below the shelf board. It is to provide. As a mechanism for raising and lowering the shelf plate horizontally, a mechanism using a parallel link called a normal pantograph shown in FIG. 5 is known. In FIG. 5, the highest rising position is shown by a solid line, and the lowest descending position is shown by a chain double-dashed line. That is, the shelf board 501 and the base board 50
Guides 503, 504 parallel to both opposite positions of 2
And the pair of axes 505, 506 that rotate around the center line of this guide.
Is provided, and links 507 and 508 of equal length are rotatably connected at the center to form an X-shape. One end portion 509 and 510 of the upper and lower sides of the link are rotational pairs by shafts 505 and 506, and the other end is formed. The end portions 511 and 512 are guides 503 and 50.
4 is connected to the shelf plate 501 and the base plate 502 as a sliding pair. The shelf plate 501 is provided with a slope 513 for allowing the vehicle to be smoothly loaded and unloaded by itself. In this mechanism, the shelf plate 501 is always kept horizontal and moves in parallel.

[0004]

In this case, since the shelf plate is kept horizontal even in the lowest lowered position, and a space for a mechanism part for accommodating the links and the like is necessary at the lower part of the shelf plate, the shelf plate and the ground are naturally required. There is a step between and. Therefore, in order to accommodate entry and exit of the vehicle, it is necessary to provide a slope for guiding the vehicle at the entry and exit port of the shelf plate, and that portion projects and becomes a dead space. In addition, mechanical and dimensional restrictions are unavoidable on the mechanical parts such as the links formed under the shelf. However, it is not always necessary for the shelves to move horizontally up and down for vehicles that move in and out by themselves.

An object of the present invention is to stably hold a vehicle in which the shelf board is tilted so that the entrance / exit opening side is slightly higher at the highest rising position, and is stably held at the lowest descending position. The shelf top and bottom type has a small dead space that allows vehicles to be loaded and unloaded by tilting it until it almost touches the ground.
An object of the present invention is to provide a two-level multi-level parking device that is economical to construct and maintain, which enables expropriation of two passenger cars on the site of one car.

[0006]

In order to achieve the above object, in the two-stage multi-level parking apparatus of the present invention, one side is used as a loading / unloading port, and one wheel stopper is provided on the opposite back side. A shelf plate on which at least four wheels of the vehicle can be mounted, upper guide rails provided on both sides of the shelf plate in a direction parallel to the shelf plate from the entrance side to the rear side, and the upper guide rails. An elevating table member including an upper bearing bracket fixed to an end portion on the back side of the extension of the guide rail is provided. On the other hand, a base including a lower guide rail extending in the same direction generally directly below the upper guide rail, and a lower bearing bracket fixed almost directly below the upper bearing bracket substantially above the lower guide rail. Install the frame on the ground.

An upper end of the upper bearing bracket is pivotally supported by the upper bearing bracket and a lower end is guided by the lower guide rail to linearly move between the elevating table member and the base frame, and the lower bearing bracket. The lower end is rotatably supported by a shaft and the upper end is guided by the upper guide rail so as to be linearly connected, and the response link and the interlocking link are rotatably connected to each other by a connecting shaft. Configure the link mechanism. The four link mechanisms are simultaneously actuated by the driving members to move left and right at the same time to move up and down the elevating table member in a generally translational manner, and at the highest rising position, the shelf board inclines with the entrance and exit sides slightly higher and the lowest descending position. Then, the shelf plate is configured to be inclined so that the back side is raised and the end of the loading / unloading port is almost grounded.

Further, the drive member is a long-axis screw member axially supported in parallel with the upper guide rail, and is screwed onto the screw member, and is guided by the upper guide rail along with the rotation of the screw member to form a straight line. A moving drive block; and a drive link having an upper end pivotally supported by a support shaft provided on the drive block and a lower end pivotally supported on a support shaft provided at the response link,
The drive link is configured to swing within a range from a position close to the interlocking link to a position perpendicular to the lower guide rail.

[0009]

The vertical movement of the lift table member including the shelf board on which the vehicle is mounted is performed by rotationally driving the screw member provided on the lift table member and linearly moving the drive block along the upper guide rail. It is performed by a Scott-Russell mechanism composed of a drive link pivotally supported on the block and a reaction link pivotally supported on the base frame.

Since the interlocking link and the response link are dimensioned so as to support the entrance / exit opening side of the shelf board slightly higher at the highest rising position, the mounted vehicle moves toward the entrance / exit opening due to vibration or the like. It does not move and there is a wheel stop on the back side, so the vehicle is supported stably. Further, when descending, the lift base member moves substantially in translation, the upper end of the interlocking link lowers earlier than the upper end of the response link, and the lift base member itself gradually inclines so that the loading / unloading port of the shelf board faces downward. While descending.

Since the shelf board at the lowest lowered position is in an inclined state in which the end portion of the entrance / exit opening is almost coincident with the grounding surface of the base frame, the vehicle at the time of entrance enters the inclined surface by itself,
It can be mounted on the shelf in a state of being tilted back and forth, similar to when stopped on a slope. When the lift table member is raised from this state, a space for accommodating another vehicle can be provided under the lift member at the highest lift position.

Further, in the lowest lowered position, since the lower side of the tilted lift member forms a wedge-shaped space in which substantially triangular prisms are laid horizontally, it is possible to construct the link mechanism in this space. On the other hand, at the lowest lowered position, the angle formed by the axis of the drive link and the upper guide can be made larger than the angle formed by the axis of the interlocking link and the upper guide.
The starting torque of the ball screw is less than directly driving the interlocking link.

Further, since the linear movement distance of the upper end of the drive link can be made larger than the linear movement distance of the upper end of the interlocking link, if the work amount is the product of the force and the movement distance, the drive block pivotally supporting the upper end of the drive link is interlocked. The entire stroke can be driven with less force than directly driving the link. Therefore, the burden on the ball screw is reduced, and the service life can be increased.

That is, the outer periphery of the head portion 85 is fitted into the fitting hole 93 that is concentric with the connecting pipe 89 provided in the flange 91 that is integrally fixed to both ends of the connecting pipe 89. On the other hand, since the flanges 91 on both sides of the connecting pipe 89 are respectively connected to the interlocking links 73 by the bolts 95, the left and right interlocking links 73 rotate integrally via the connecting pipe 89.

Are provided respectively.

In this embodiment, at the highest rising position A of the lifting table member 51 shown by the solid line in the figure, the shelf board 11 has the loading / unloading port 13 such that the rear side 14 on the right side of the figure is slightly lower than the horizontal position. The side is slightly raised and tilted, and at the lowest lowered position B shown by the chain double-dashed line in the figure, the end of the loading / unloading port 13 of the shelf board 11 is tilted until it almost matches the ground plane of the base frame. The dimensions between the centers P, Q and R, S of the shafts provided at the ends of the link 61 and the interlocking link 73 are determined, and the connecting shaft 9
The position of the axis C of 7 is selected.

A drive link 107 is provided with a bifurcated bearing plate 109 fixed to the upper end by a bolt (not shown), and the bearing plate 109 supports the bifurcated bearing plate 109 to support an axle 113 planted in a drive block 111. The drive block 111 is screwed with the ball screw 27, and is linearly moved by being guided in the upper guide rail 23 by a wheel 117 of a rolling bearing which is axially attached to the axle 113 via a spacer 115. The rolling bearing wheel 117 is retained by a retaining ring 119. FIG. 4 is a sectional view taken along the line IV-IV in FIG. 1 and shows the relationship between the upper guide rail 23, the ball screw 27 drive link 107 and the drive block 111.

The lower end of the drive link 107 is rotatably supported by a support shaft 121 provided below the connecting shaft 97, and the axis 1 connecting the centers U and V of the shafts provided at the upper and lower ends of the drive link 107.
It is configured to swing within a range in which 23 is inside the axis 101 of the interlocking link and does not exceed the position perpendicular to the base frame 53. By interposing the drive link 107 in this way, when the elevating base member 51 is raised from the lowest lowered position against the vertical load, the angle α formed by the axis of the drive link and the upper guide at the lowest lowered position. Since the axis of the interlocking link can be configured to be larger than the angle β formed with the upper guide, the axial force applied to the ball screw 27 constitutes the Scott-Russell mechanism only by the reaction link 61 and the interlocking link 73, and the interlocking link is formed. The axial center S of the upper end of 73 can be made smaller than that in the case where the ball screw 27 axially operates.

The drive block 11 screwed with the ball screw 27 by controlling the rotation of the ball screw 27 by a known drive source (not shown) which is power-connected to the drive shaft 39.
1 is guided by the upper guide rail 23 and moves linearly.
Therefore, in principle, the Scott-Russell mechanism has the center points P and V as the turning pairs and the center points Q and U as the sliding pairs, and the sliding movement of the center point U separates the two center points Q and U from each other. And approach. By this operation, the lifting table member 5
1 can be raised or lowered.

When the lifting table member 51 is lowered, the shelf board 11
Reaches the lowest descent position B with the loading / unloading port 13 grounded. The vehicle is allowed to self-propel and ride on the shelf board 11, and after confirming that all wheels are on the shelf board 11, the vehicle is stopped. After the driver gets off the vehicle, when the lift table member 51 is raised to the maximum raised position, the shelf board 11 supports the vehicle 15 in an inclined state in which the loading / unloading opening 13 is slightly raised. Even if some external force such as vibration is applied, since the loading / unloading port 13 is high, the vehicle 15 does not move to the loading / unloading port 13 side. Further, the wheel stop plate 47 prevents the movement in the inclined direction.

A sufficient space for accommodating the vehicle 125 is provided between the four link mechanisms on the lower side of the lifting table member 51, so that the driver's cab can be received without interference of the response link 61 and the interlocking link 73. Vehicle 1 at a position where the door can be opened and closed
25 can be stopped and stored.

A preferred dimension in one embodiment of the two-stage multi-storey parking system according to the present invention is, if the distance between points P and Q in FIG. 1 is represented by P-Q, P-Q = 2100 mm. RS = 2500 mm and UV = 1200 mm. Also, the distance between point C and RS is 340 mm, and point C
And the distance between P and Q is 190 mm. On the other hand, points V and P
The distance from -Q is 245 mm. Furthermore, R of CS
-S projection is 1450mm, C-Q P-Q
Is 1150 mm and VQ is 1000 mm. However, it goes without saying that the two-stage multi-level parking apparatus of the present invention is not restricted by such dimensions and can be implemented with other dimensions.

[0029]

According to the two-stage type three-dimensional parking apparatus of the present invention,
Since the loading / unloading port side is grounded and inclined at the lowest lowered position of the elevating / lowering member, the vehicle can be mounted on the shelf board by itself without providing an inclined guideway, and a small installation area can be constructed. In addition, at the highest lifted position, the entrance / exit entrance side is slightly inclined, and the wheel stoppers are provided on the opposite back sides.Therefore, the vehicle mounted on the shelf board has a wheel stopper provided on the entrance / exit side separately. It is supported stably even without it.

Further, a drive link operated by a drive block screwed to the screw member is separately provided, and is configured to swing within a range from a position close to the interlocking link to a position perpendicular to the upper guide rail. By increasing the rising angle of the drive link with respect to the screw member and expanding the movement range of the drive block, the load on the screw member when moving the lifting table member up and down is reduced, and the useful life of the screw member is reduced. Can be increased.

According to the structure of the two-stage type multi-level parking apparatus according to the present invention, since it has a simple structure without a pillar or the like requiring a foundation, it is possible to fold and transport the factory assembly instead of constructing it locally. This facilitates temporary installation and removal of event venues, etc., and enables economical construction and maintenance.
