etc. are known.

Such a multilevel parking device has the advantage of being able to effectively utilize space in a narrow area.

[Problem that the invention attempts to solve]

However, the above-mentioned conventional movable floor lifting mechanism of the multilevel parking system has the following problems. That is, in the case of the conventional example, when winding up the lifting chain, a pulling force in the lateral direction (arrow a) is applied to the chain that passes between the upper parts of the columns and raises the movable floor, so a lateral force is also applied to each column. In addition, in the case of the conventional example, since the upper and lower pallets are raised and lowered while pulling the lower part of the hollow support, a lateral force acts on the fixed support, so against the lateral force applied to the support, The fixed pillars (four pillars) must be made larger to withstand the support, or cross beams are required for reinforcement, which requires a large amount of material and time, and requires a large amount of power to move up and down.

In the case of the conventional example, all the ropes for lifting the movable floor are wound around the winding sheave and unwinded, so the winding sheave needs to have a large structure, and the rope for lifting the movable floor is wound around the winding sheave. When taking up the movable floor, there may be a shift in the winding portion, making it impossible to wind up each rope for lifting and lowering the movable floor uniformly, and there are also cases where the winding balance is lost and the movable floor cannot be raised and lowered in a horizontal state.

There are other problems.

The present invention was devised to address the above-mentioned problems, and its purpose is to uniformly raise and lower a movable floor using a rope for raising and lowering the movable floor, and to maintain the horizontal state of the movable floor. It is an object of the present invention to provide a movable floor elevating mechanism for a multi-story parking system that can be maintained, save materials as much as possible, and reduce the power source.

[Means for solving problems]

The movable floor elevating mechanism of the multilevel parking system of the present invention as a means for achieving the above object has pillars erected at corner positions of the movable floor to hold the movable floor in a horizontal state. In a movable floor elevating mechanism of a multi-story parking system in which the floor is raised and lowered vertically and horizontally along the pillars, an elevating chain is suspended from one particular pillar among the pillars via a winding sheave; The lower end of the lifting chain is fixed to a corner position of the movable floor corresponding to the specific support, and a general pulley is provided at the bottom of the specific support, and pulleys are provided at the upper and lower parts of the support other than the specific support. Further, one end of a movable floor suspension rope is fixed to each corner position of the movable floor corresponding to each column other than the specific column, and the other end of each movable floor suspension rope is wound around a pulley at each of the upper and lower portions. At the same time, each movable floor is suspended by winding it around the general pulley and fixing it at a corner position of the movable floor corresponding to the specific support column, and winding up or lowering the lifting chain via the winding sheave. The structure is such that the movable floor can be raised and lowered in a horizontal state via ropes.

Here, in the above configuration, an electric motor powered by a 100V power source is normally used as the drive source for raising and lowering the elevating member, and the movable floor is a rectangular movable floor, and each corner of the rectangular movable floor is The structure has pillars erected in the middle. In addition to a normal chain, the elevating chain includes a rope or other traction device that can be wound up and unwound, and the movable floor suspension rope includes a traction device such as a chain.

[Effect]

The movable floor elevating mechanism of the multi-story parking system of the present invention based on the above configuration requires other steps to raise the elevating chain hanging from a specific support among the supports installed at the corners of the movable floor. The horizontally supported movable floor rises smoothly by support from movable floor hanging ropes suspended from the pillars via pulleys and by the lifting chain, that is, by support at each corner of the movable floor. No lateral forces act on the struts, only vertical lifting forces act on them. Further, when the elevating member is lowered, the movable floor is lowered by its own weight, and at this time, force acts only in the vertical direction on each support.

In addition, the movable floor lifting mechanism of the multilevel parking system of the present invention does not have a configuration in which the movable floor suspension ropes are directly wound around a winding sheave, but each movable floor suspension rope is fixed at a corner position of the movable floor corresponding to a specific support. The lifting chain that is hoisted up and lowered by the winding sheave is fixed at the corner position, and the lifting status of the lifting chain is transmitted to each movable floor lifting rope. The movable floor can be raised and lowered uniformly, and the movable floor can be maintained in a horizontal state.

〔Example〕

Hereinafter, embodiments embodying the present invention will be described with reference to the drawings.

Here, FIG. 1 is a perspective view showing one embodiment of the present invention. Note that the same reference numerals are given to the same corresponding parts as in FIG. 2 showing the conventional example.

In this embodiment, a two-tier multilevel parking system is used, which includes four pillars 1a, 1b, 1c, and 1d, an electric motor 3, a movable floor 5, one chain 7a, and three wire ropes 7b. , 7c, and 7d.

The four pillars 1a, 1b, 1c, and 1d are made of channel-shaped steel with one side open, and a foot plate 11 is fixed to the lower end by welding (if necessary, fixed/adhered by assembly and engagement fixation, etc.). , a top plate 12 is provided at the upper end. And each pillar 1a,
1b, 1c, 1d are four connecting members 13, 1
The pillars 1a,
Supports 1c and 1d are arranged with respect to 1b so that their open portions face each other. electric motor 3
is mounted on the top plate 12 of the support column 1a, and a winding sheave 4 is directly connected thereto. The electric motor 3
The is designed to operate with a 100V power supply for general household use.

The movable floor 5 is a steel plate with a slightly inclined vehicle entrance and exit, and each of the above-mentioned supports 1a, 1b, 1
Protrusions 5a, 5b, 5c, and 5d are provided at positions corresponding to the open grooves of the pillars 1a, 1d, and slide along the grooves of each of the pillars 1a, 1b, 1c, and 1d.

The chain 7a is unwound from the winding sheave 4 of the electric motor 3 and is wound up, and the lower end of the chain 7a is connected to the movable floor 5.
It is fixed to a piece 6 attached to a fixing part made of a protruding piece 5a.

Each of the wire ropes 7b, 7c, and 7d is
One end thereof is fixed to the protruding piece 5a of the movable floor 5,
The other ends of each of the movable floor 5 protrusions 5b, 5c,
It is fixed to 5d.

That is, the wire rope 7b has a pulley 9a attached to the lower part of the column 1a, a pulley 9g attached to the lower part of the column 1d, a pulley 9e attached to the column 1c, and a pulley 9e attached to the lower surface of the top plate 12 of the column 1c. The projecting piece 5 of the movable floor 5 passes through the fixed pulley 8b.
c, and is fixed by an adjustment bolt 10b that can adjust the length of the wire rope 7b.

The wire rope 7c passes through a pulley 9c attached to the lower part of the support 1a, a pulley 9f attached to the lower part of the support 1d, and a pulley 8c fixed to the lower surface of the top plate 12 of the support 1d, and then connects to the projecting piece of the movable floor 5. 5d with an adjustment bolt 10c.

The wire rope 7d passes through a pulley 9b attached to the lower part of the column 1a, a pulley 9d attached to the lower part of the column 1b, and a pulley 8a fixed to the lower surface of the top plate 12 of the column 1b. It is fixed to the piece 5b with an adjustment bolt 10a.

Although not shown, a dome-shaped transparent or translucent roof is attached to the top of the device.

Next, to describe the operation of this embodiment, as the lifting chain 7a is wound around the winding sheave 4 by the drive of the electric motor 3, each of the wire ropes 7b, 7c, and 7d is The other pillars 1b, 1c,
1d portion is pulled downward, and the rope portions hanging downward from each pulley 8a, 8b, 8c are interlocked to be pulled upward, thereby causing the protrusions 5a, 5b of the movable floor 5 to ,5c,5
A vertical lifting force acts on the d portion, and the entire movable floor 5 rises smoothly.

On the other hand, as the lifting chain 7a is unwound by the reverse drive of the electric motor 3, each wire rope 7
b, 7c, and 7d are similarly loosened, and the movable floor 5 as a whole descends smoothly due to its own weight.

In the case of the configuration of this embodiment, the movable floor is moved vertically and horizontally using a chain hanging down along one column, so a safety stopper is installed on the main column (specific column) side. This has the advantage that safety can be sufficiently ensured just by doing so. On the other hand, in the case of the conventional device, the safety stopper is required at least on the diagonal column of the movable floor, which can simplify the construction.

Furthermore, since the corners of the movable floor are supported in an independent manner, even if a rope or the like is cut at one or both corners, the movable floor can be supported at other corners. It also has the effect of preventing the floor from tilting.

Note that the present invention is not limited to the embodiments described above, and includes configurations that can be modified without changing the gist of the present invention. Incidentally, the term "rope" in this specification is not limited to the wire rope described in the embodiments, but is a concept that includes chains and other traction tools. Furthermore, if a rectangular hole is formed in the center of the movable floor 5, it will be easier to inspect the bottom of the vehicle.

In addition, although a two-stage system is used in the embodiment, it is also applicable to three or more stages, and it is of course possible to adopt a roof, side walls, etc. as appropriate to create a design depending on the situation. Further, the movable floor is not limited to a rectangular shape, but may have a circular, polygonal, etc. configuration, for example. In this case, the supports need to be arranged at corner positions of the movable floor that can maintain the movable floor in a horizontal state, and do not need to be arranged at the corners. Furthermore, the number of pillars is not limited to four, but may be three, five, etc. Furthermore, the engagement between the movable floor and the pillars can be achieved through projections provided at the corners of the movable floor. Instead of using one piece, for example, a notch, a hole, etc. may be provided in the movable floor, and the support pillar may be engaged by fitting into the notch, hole, etc. Furthermore, the support column is not limited to grooved steel, and may be simply a columnar body or a structure in which a plurality of columns are arranged to form a single column body.

[Effect of idea]

As is clear from the above description, according to the movable floor elevating mechanism of the multilevel parking system of the present invention, the movable body suspension rope is not directly wound around the winding sheave, but the corner of the movable floor corresponding to a specific support is Each movable floor suspension rope is fixed at a position, and a lifting chain that is hoisted up and lowered by a winding sheave is fixed at the corner position, and the lifting state of the lifting chain is transmitted to each movable floor suspension rope. As a result, the movable floor can be raised and lowered uniformly using the rope for raising and lowering the movable floor, and the movable floor can be maintained in a horizontal state.

In addition, the lifting force acting on one corner of the movable floor on one specific column is transmitted through each rope to each corner position of the movable floor that is independently suspended on other columns. Since only vertical loads are applied, i.e. there are no lateral forces acting on each column, there is no need for larger columns or reinforcing cross beams to make the columns stronger, and therefore the material can save
This has the effect of simplifying device production.

In addition, as a result of eliminating unnecessary lifting force (lateral force applied to the column), it is possible to reduce the driving force for lifting and lowering, as only a single motor from a household 100V power supply is required.
