Description

[Detailed Description of the Invention] [Industrial field of application] The present invention prevents left and right tilts that occur when a cantilever-supported vehicle mounting base plate is raised and lowered, and synchronizes the left and right raising and lowering movements.
In addition, the present invention relates to a parking device capable of raising and lowering a balanced vehicle-mounting base plate without causing an error in this synchronizing operation during use.

[Conventional technology]

Conventionally, as a parking device for raising and lowering a vehicle-mounted support base plate in a cantilevered state and for raising and lowering the base plate only on one side in the width direction, for example, there is one disclosed in Japanese Utility Model Publication No. 56-34123. This parking device is connected to a drive sprocket of a geared motor that is provided by connecting the lower surface of a cantilever-supported vehicle mounting support plate and the other end of the drive cable fixed to the upper end of one support to the upper end of the other support. The base plate is moved up and down by moving the drive rope up and down. However, when the vehicle is placed on the vehicle mount base plate and moved up and down, the wheels are not always located at the center of the base plate, and when the wheels are offset, the driving force by the geared motor is As it is biased toward one side edge, the side edges in the width direction of the base plate do not always move up and down in a state where they are in sync with each other, and the vertical movement of the other end causes damage to the vertical movement of the other end, resulting in a balance of the base plate. It may not be possible to move up and down in this state. Therefore, in order to synchronize the ascending / descending speed of both ends of the base plate, two balance chains are attached to the rear ends of both base plates from the upper end of the column to the rear end of the base plate through the rear end of the base plate. The sprocket at one end of the axle pivotally supported at the end and the pulleys at the stanchions are intended to synchronize the ascending and descending speeds on both sides in the width direction of the base plate provided by the geared motor.

Further, in Japanese Utility Model Laid-Open No. 64-33863, four columns for supporting a vehicle mounting base plate are provided, and racks are provided in the up-down direction on the opposite surfaces of the front and rear columns, respectively. The front and rear parts of the base plate are rotatably provided with shaft members in the left-right direction corresponding to the front and rear columns, and pinions for engaging the racks are provided at both ends of the shaft member, and the front and rear shaft members are provided with a sprocket and a chain. There is described a parking device which is interlocked and linked with each other, and one of the shaft members is rotationally driven by an electric motor to synchronously rotationally drive four pinions so as to elevate and lower a vehicle mounting support base plate along a column.

[Problems to be solved by the device]

In the former parking system, the geared motor surely causes the base plate to lean toward one side as a result of upward and downward movement, especially upward movement, but the base plate tends to tilt to one side, but the tuning device on the left and right sides of the base plate balances with the sprocket. When the vehicle is supported by a chain, and the vehicle is supported on the bed, the load on the bed tends to tilt the bed forward.As a result, the sprocket at the rear end of the bed is a balance chain. Will be pulled up. That is, the balance chain also plays a role of restricting the rear end of the cantilever-supported base plate from moving upward, and the sprocket and the balance chain try to rotate in synchronization with each other, but of the mounted vehicle. Since the position often deviates to the left or right on the base plate, naturally the load is applied to the deviated direction,
Since the base plate side end on the side not deviated tilts upward,
The upper motive power that the left and right sprockets give to the left and right balance chains will be different. As a result, since the lower end of the balance chain itself is fixed, there is a difference in the length extended upward by the left and right balance chains during use, and it is originally intended to maintain the parallelism when the base plate is moved up and down. Sprocket and balance chain
Actually, due to the different extension of the balance chain during its use, it may not be possible to keep the balance of this base plate.

Further, in the latter parking device, the four pinions are synchronously driven to move up and down the vehicle mounting support base plate, so that the vehicle mounting support base plate can be lifted up and down with good left and right pinions. Since the load of the vehicle is supported by four sets of rack and pinion mechanisms, the racks and pinions are heavily worn and there is a problem in durability. In addition, it is extremely difficult to configure a complicated shape such as a rack or pinion with a member that has excellent strength and rigidity and is homogeneous, and it is possible that the rack and pinion will be damaged during use. It can be said that it is impossible to directly raise and lower the vehicle-mounting and supporting base plate using the mechanism in consideration of durability and safety.

SUMMARY OF THE INVENTION An object of the present invention is to provide a parking device that can smoothly and evenly lift a vehicle-supporting base plate even if a biased load is applied to the vehicle-supporting base plate.

This is a means for adjusting the vertical movement speed of both sides of the base plate 2 for raising and lowering the base plate 2 in an equilibrium state by preventing the base plate 2 from tilting sometimes. First, the pillar-shaped support member 1 of the parking device according to the present invention has a base member 7 having a U-shape in plan view as shown in the drawing, or a simple plate member not shown, and further, the lower end thereof is erected so as to be opposed to the inner and outer sides of the parking space. The left and right pairs are provided. This columnar support member 1 is provided with two H-shaped steels 8 spaced apart from each other in the front and rear as shown in the figure, and a pair of left and right H-shaped steels are provided, and the upper ends thereof are connected and fixed to each other to form the columnar support member 1. H like this

As described above, the inclined surface is provided, and the rear end portion is internally mounted on the columnar support member 1 in a cantilevered state, and is supported so as to be movable up and down by each device described later. Then, in order to maintain the cantilevered state of the columnar support member 1 and prevent horizontal shake in the horizontal direction,
As shown in the figure, a horizontal lateral shake preventing means 3 and a cantilever supporting means 4 which can slide up and down are provided. Horizontal shake prevention means 3
Basically, it simply prevents the vehicle mounting support base plate 2 that moves up and down between the columnar support members 1 from horizontally swinging, and with respect to the facing inner surface of the columnar support members 1,
A simple slider or the like may be provided as long as the rear side surface of the vehicle-mounting base plate 2 is in contact with the vehicle-mounting base plate 2 so that it can slide up and down. As shown in FIG. 2, in the example shown in the drawing, a column 11 is erected upward from the rear end of the base plate 2, and a horizontal shake-preventing roller 12 is projecting from the column 11 to the side. In the channel portion 8b of the H-shaped steel 8 serving as the columnar support member 1, the bottom surface of the channel portion 8b and the surface of the roller 12 are installed with a clearance that allows the vertical movement of each other. That is, two supporting pieces 13 are provided on the side of the member so as to project, and the roller 12 is rotatably supported in a direction orthogonal to the base plate 2. Further, as the cantilever support means 4, since the base plate 2 is in the cantilever support state, it can support the load of the mounted vehicle and can move the rear part of the base plate 2 up and down with respect to the columnar support member 1. A variety of supporting members can be used, but in the example shown in the figure, a shaft 14 is provided so as to project laterally from the column 11 of the base plate 2, and a roller 15 is parallel to the base plate 2 on the shaft 14. It uses the one that is rotatably supported in various directions. Moreover, this roller
It is preferable to use a plurality of 15 at a distance from each other in the vertical direction of the pillar 11 standing upright. The lower roller 15 is the base plate 2
The upper roller 15 located on the side of the rear end is located on the upper side of the rear end, and stably supports the cantilevered support state of the base plate 2 at a plurality of positions such as two points separated from each other. There is. Then, the roller 15 is mounted inside the channel portion 8b of the columnar support member 1 to support the base plate 2 in a cantilevered state. Next, the lifting / lowering means 5 for the cantilevered base plate 2 fixes one end of the drive rope 16 such as a chain to the upper end of one of the columnar support members 1 as shown in the drawing, and lowers the base plate 2 downward. While getting the two guide gears 17 and passing them over, the other end is
As shown in the drawing, the channel portion 8b of the other columnar support member 1 is guided upward, and is associated with the elevating and lowering drive means 20 represented by the drive sprocket 19 of the geared motor 18 located at the upper end, and the end portion of the columnar support member 1 is connected. The one fixed in place is used. That is, the vehicle mount base plate 2 is supported at its rear end by the horizontal shake preventing means 3 and the cantilever support means 4 at the channel portion 8b of the columnar support member 1, and the vehicle is mounted on the base plate 2. However, the vehicle mounting support base plate 2 is supported on the columnar support member 1 by being cantilevered and the drive rope 16 is wound up or rewound by the elevating drive means 20 on one columnar support member 1. It goes up and down. However, at this time, since the elevating drive means 20 is provided on one side of the base plate 2, the elevating drive means 20 side of the vehicle mounting support base plate 2 is
As a result of being given a stronger lifting force, especially ascending force, than the opposite side, the right end tends to rise faster in the case of the base plate 2 when moving up and down, but both ends can move up and down in synchronization. It is desired, and naturally, when the vehicle is mounted on the base plate 2, the mounting position may deviate from the center position of the base plate. At this time, both ends are moved up and down in a balanced state in synchronization. Is desired. In order to solve these problems, in the present invention, both side end elevation speed synchronizing means 6 of the base plate 2 are provided. Here, the both side end up-and-down speed tuning means 6 of the base plate 2 means one axle whose both ends are projected laterally from the base plate 2.
21 is pivotally supported in the width direction of the base plate 2, and pinions 22 are fixed to both protruding ends of the axle 21, and a rack 23 that meshes with the pinion 22 is erected on the side of the base plate 2 so that both left and right sides are supported. The pinion 22 meshes with both the left and right racks 23 and is set so as to be able to rotate in synchronization. Therefore, the rack 23 has the columnar support member 1
Although it may be erected independently from the above, in the illustrated example, a pinion that meshes with the rack 23 is used by using the one fixed to the surface 8a of the rear H-shaped steel 8 as the columnar supporting member 1.
As shown in FIG. 22, it is set at a position rearward of the base plate elevating means 5. The vehicle mounting / supporting base plate 2 is moved up and down by the base plate elevating means 5, and the pinions 22 on both sides of the base plate 2 are set to rotate in synchronization with one axle 21 in accordance with the vertical movement at this time. Therefore, the pinion 22 meshes with the rack 23 fixed to the columnar support member 1 and synchronously rotates to move the base plate up and down in equilibrium. That is, even when the drive cord 16 is moved up and down from the right side of the base plate 2 in the drawing by the engagement of the rack 23 and the pinion 22 and the rotation of the geared motor 18 as the lift drive means 20, the left and right side ends of the base plate 2 are Due to the meshing relationship between the rack 23 and the pinion 22, the position is restricted and only one side is
It moves up and down quickly and goes up and down in equilibrium without tilting. In the illustrated example, the rack 23 and the pinion 22 are set rearward of the base plate elevating means 5, but are set forward of the cantilever support means 4.
The load when the vehicle is mounted on the vehicle mounting base plate 2 is basically supported by the cantilever support means 4 at the rear end, but the load is also applied to the rack 23 and the pinion 22. As shown in FIG. 4, the rack 23 and the pinion 22 are located on one side of the pinion 22 in order to prevent abrasion, damage, etc., and a failure due to excessive meshing. The cantilever support means 4 is mounted on the rack 23 and the pinion 22 by attaching the load receiving guide wheel 24 whose outer surface abuts the surface 8a of the rear H-shaped steel 8 as the columnar support member 1 in a state of maintaining the meshing relationship of. It is possible to prevent the load of the vehicle mounted on the base plate 2 from being directly applied to the rack 23 and the pinion 22 even in the rear. In order to prevent the vehicle load from being directly applied to the rack 23 and the pinion 22,
As shown in FIG. 5, a rack 23 is provided on the back surface of the columnar support member 1, and a pinion 22 is provided on the base plate 2 rearward of the cantilever support means 4.
It may be provided at the rear end. Further, as shown in FIG. 6, the tuning means 6 constituted by the rack 23 and the pinion 22 is set in the same state as in FIG. 1, and is brought into contact with the back surface of the front H-section steel 8 located in front of the tuning means 6. On the base plate 2 and the support 11a
And the roller 15a is pivotally supported on a shaft projecting to the upper side of the column 11a, and the roller 15a is brought into contact with the back surface of the front H-shaped steel 8, and thus the roller 15a and the base The cantilever state and the horizontal shake-prevented state can also be obtained by the rollers 12 of the horizontal shake-prevention means 3 provided on the side of the rear end of the plate 2.
In addition, the horizontal lateral shake prevention roller 12 is specially arranged as described above.
Alternatively, it can also be obtained by the rack 23 and the pinion 22. That is, by using the rack 23 and the pinion 22 as the helical rack and the pinion, it is possible to achieve the synchronization of the left and right vertical movements and the lateral shake prevention at the same time.

Thus, in the parking device according to the present invention, the base plate is cantilevered by the columnar support member, and the elevating and lowering drive means 20 provided on one side of the columnar support member 1 drives the drive line provided below the base plate 2. 16 is moved up and down by one side suspension method by vertical movement, and its cantilever support and lateral shake prevention are performed by the cantilever support means 4 and the horizontal lateral shake prevention means 3, but the vehicle mounting support base plate 2
Because both ends of the width direction of the
As the ascending / descending speed tuning means 6 by the 23 and the pinion 22 is provided, the rack 23 and the pinion 22 are securely supported without being displaced and tilted during use, and at the same time the rack 23 and the pinion 22 are synchronized. The means 6 part, together with the cantilever support means 4 and the base plate elevating means 5, also supports the base plate 2 when moving up and down. Above all, the rack
Pinion 23 fixed to the front surface of the rear H-section steel 8 of the columnar support member 1 made by arranging two H-section steels in parallel, and engaging with this
22 is rotatably provided on one axle 21 pivotally supported on the base plate 2 and is related to each other, so that the rack 23 and the pinion
22 also supports the base plate 2 in cooperation with the cantilever support means 4 located behind this. Further, as the columnar support member 1, an H-shaped steel 8 as shown in the figure or another U-shaped steel,
Two front and rear members each having a channel portion 8b on its side surface are provided side by side, and a pair of these members are paired so that the front plate elevating means 5 is provided on the front H-shaped steel 8 and the horizontal deflection is provided on the rear shaped steel 8. The prevention means 3, the cantilever support means 4, and the both end elevation speed synchronizing means 6 of the base plate 2 can be attached. Further, by arranging the tuning means 6 rearward of the lateral shake prevention means 3 and the cantilever support means 4, it is possible to prevent the vehicle load from being directly applied to the rack 23 and the pinion 22 portion.

[Effect of device]

As described above, in the parking apparatus according to the present invention, the pinions at both ends of the rotatably supported axle of the vehicle mounting base plate are respectively engaged with the racks fixedly erected along the pair of support members. Therefore, when the vehicle loading support base plate is raised and lowered by the lifting means, the left and right pinions rotate synchronously, and both ends of the vehicle loading support base plate move up and down in synchronization with each other. Even when a biased load is applied, it is possible to raise and lower the vehicle mounting base plate with the upper surface horizontal without tilting. Moreover, most of the weight of the vehicle mounting and supporting base plate and the vehicle mounted on it is supported by the base plate lifting means, and a large load does not act on the rack and pinion, so that the durability of the rack and pinion can be improved. Even if the rack or the pinion is damaged, the vehicle mounting base plate and the vehicle mounted on it can be reliably prevented from falling, and the safety of the parking device can be sufficiently ensured.

By using a pair of standing two shaped steels having a channel portion as a columnar support member and providing a rack on the surface of the shaped steel behind them, the base plate lifting means can be internally provided in the shaped steels.
Further, horizontal lateral shake preventing means and cantilever supporting means can be provided in the rear die steel, and the overall compact device can be put together.

By maintaining the meshing state of the rack and pinion on one side of the pinion and providing a guide wheel with a radius larger than that on the same axle, the load by the supporting vehicle is not directly applied to the rack and pinion, This part can be protected.In addition, as horizontal horizontal shake prevention means, a support piece is provided on the side surface of the column standing upright on the rear end of the base plate, and a roller is attached to this support piece in a direction orthogonal to the base plate. Lateral movement is prevented by using a pivotally rotatably supported cantilevered support means that has a roller that is rotatably pivoted in a direction parallel to the base plate on a shaft that projects laterally from a support post of the base plate. The cantilever support can be stably and reliably performed, and the rollers as the cantilever support means are vertically spaced apart from each other, whereby the support for the base plate is strengthened.
