Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a two-stage parking device that allows a vehicle to be smoothly loaded and unloaded in each of the upper and lower two stages without excessively burdening the driver.

[0002]

[Prior Art]

 The conventional general two-stage parking device includes an upper parking pedestal, a support frame, a lifting drive device, a pillar structure arranged at each of four corners of the support frame, and the lifting drive for the pillar structure. A roller chain and a sprocket that are interlocked with the device are provided, and the drive device simultaneously rolls up the roller chain via the sprocket to move the car upward together with the parking garage above the second car above the second car height. Then, the parking lot for the second vehicle is created.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional technology, since the upper parking lot is only moved up and down horizontally, even if the upper parking lot is lowered to the maximum extent, a step is created between the parking lot and the car, and the car gets on and off the parking lot at the upper stage. At this time, the car body and the driver are shocked. Also, in order to lift a passenger car to the upper parking lot, it is necessary to slightly increase the engine to increase the moving power of the car. Furthermore, since each pillar structure is provided with a sprocket and it is necessary to drive these sprockets synchronously, the parking system as a whole has a significantly complicated structure.

The present invention has been devised in view of the above circumstances, and has a simple structure for synchronously ascending / descending the upper parking pedestal. It is an object of the present invention to provide a two-stage parking device that can perform forward ascent or descent operation of a parking lot.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention uses a link mechanism having a simple structure as a lifting guide mechanism, paying attention to the fact that the link mechanism can be easily moved up and down in synchronization without opening and closing. In addition, the link mechanism is formed on an inclined surface provided on the lower surface of the vehicle mounting table, which is the upper parking pedestal, in cooperation with the vertical movement of the link mechanism while exerting a constant supporting force. It is intended that the vehicle mounting table can be easily moved up and down by moving it within a predetermined range while one end is in rolling contact. Specifically, a support frame, a vehicle mounting table arranged above the support frame, a support frame and the vehicle mounting table are provided between the support frame and the vehicle mounting table. An elevating guide mechanism that supports the loading table so that it can be moved up and down, and a drive that is provided between the support frame and the vehicle loading table and that moves the vehicle loading table up and down above the support frame. It is premised on a two-stage parking device equipped with a device. Cam plates are provided on both sides of the lower surface of the vehicle mounting table at positions slightly rearward, and the elevating guide mechanism is provided between both side portions of the vehicle mounting table and both side portions of the support frame. A pair of X-shaped link mechanisms, the rear end of which is pivotally supported by the rear end of the vehicle mounting table, and the front end of which is rolled on the upper side surface of the support frame. One of the links brought into contact with each other and the rear end thereof are pivotally supported by the rear end portion of the support frame, and are bent in a dogleg shape from the middle portion to the front end portion. The other link that rolls over the top and the intermediate part where these one link and the other link intersect are a two-tiered parking system that is pivotally connected by a connecting pin.

[0006]

[Action]

 The operation of the present invention having the above-described structure is as follows. In order to prevent the vehicle mounting table from forming a step with the ground on which the parking device is installed, the vehicle is placed on the vehicle mounting table with the vehicle lowered to the front, and then the drive device is moved upward. Let Then, the pair of link mechanisms start opening simultaneously, and the front end of one link moves backward on the upper surface of the side of the support frame, and the front end of the other link moves backward on the cam plate. They move while rolling and touching each other. At this time, the pair of link mechanisms try to vertically lift the vehicle mounting table while opening them synchronously, so that only the vertical component of the backward movement distance on the cam plate is applied to the vehicle. The front of the mounting table rises extra. For this reason, the vehicle mounting table, which was initially in the front-down state, eliminates the front-down state. After that, if the driving device is continued to move upward and the rolling movement distance of the front end of the other link is extended to the rear, the vertical component increases, and the vehicle mounting table moves forward. It goes up. Then, when the vertical height of the space between the support frame and the vehicle mounting table becomes slightly higher than the vehicle height of the vehicle to be stored later, the operation of the drive device to the ascending side is stopped. When the vehicle mounted on the vehicle mounting table is to be unloaded, the vehicle parked between the support frame and the vehicle loading table is unloaded, and then the drive device is operated to the descending side. .. Then, the pair of link mechanisms simultaneously start the closing operation, and accordingly, the front end of one link moves forward on the upper surface of the side of the support frame and the front end of the other link moves forward on the cam plate. Move while rolling and touching. At this time, the pair of link mechanisms try to lower the vehicle mounting table vertically while closing them synchronously, so that only the vertical component of the forward movement distance on the cam plate is measured. The front of the vehicle mounting table is lowered further. Therefore, the vehicle mounting table, which was initially in the forward-raised state, eliminates the forward-raised state. After that, if the driving device is continued to move downward to extend the forward rolling distance of the front end of the other link, the vertical component increases and the vehicle mounting table moves forward. The state begins to change. At this time, since the other link is bent in a dogleg shape from the middle portion to the front end portion, it does not come into contact with the lower surface of the vehicle mounting table. Then, when the front end of the vehicle mounting table comes into contact with the parking device installation ground, the operation of the drive device to the descending side is stopped. After that, when the vehicle mounted on the vehicle mounting table is moved forward, the vehicle is smoothly delivered without any shock.

 Next, preferred embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows the two-stage parking apparatus according to this embodiment as viewed from the front, FIG. 2 shows the same as viewed from the side, and FIG. 3 shows an enlarged view of the rolling contact of the rollers with respect to the cam plate. FIG. 4 shows the case seen from the front, FIG. 4 shows the case seen from the side, FIG. 5 shows the case of the structure of the support frame seen from the plane, and FIG. 6 shows the enlarged structure of the link mechanism. As shown in FIGS. 1 and 2, reference numeral 1 denotes a two-stage parking apparatus according to this embodiment, which includes a support frame 5 installed on a parking apparatus installation ground 3 and an upper portion of the support frame 5. An installed vehicle mounting table 7, and a pair of link mechanisms provided between the vehicle mounting table 7 and the support frame 5 and supporting the vehicle mounting table 7 so as to be able to move up and down on both sides. 9 and a hydraulic cylinder 11 which is an example of a drive device for opening and closing the pair of link mechanisms 9. The vehicle mounting table 7 is a plate having a rectangular shape with an appropriate thickness, and a car stopper 17 which is slightly longer than a space between a pair of rear wheels 15 of the vehicle 13 mounted behind the table upper surface 7a. The front end of the table upper surface 7a is formed into a tapered gentle sloping surface 7b, and cam plates 19 are provided at positions slightly rearward on both sides of the table lower surface 7c. As shown in FIGS. 3 to 4, the cam plate 19 moves at a certain angle (from this side to the left side in FIG. 3) from the front side to the rear side (right side to left side in FIG. 3) of the vehicle mounting table 7. The angle is determined in relation to the ascending / descending stroke of the vehicle mounting table and the state of upward and downward movement of the vehicle mounting table.) A cam portion 191 formed on the bottom of the vehicle mounting table 7 and a bent portion 192 formed integrally with the cam portion 191 so as to be appropriately rounded down to the lower surface 7 c of the vehicle mounting table 7. It is configured. As shown in FIG. 5, the support frame body 5 has side frame bodies 21 each having a U-shaped cross-section on both sides, and a erection plate body 23 is provided on the front side of the side frame body 21 and a rear end thereof. An erection frame body 25 having an L-shaped cross section is erected on each part. As shown in FIG. 6, each of the pair of link mechanisms 9 has a substantially V-shaped plate body 271, 271 which is parallel to each other and is bent in a slight dogleg shape from the intermediate portion to the front end portion. It is composed of a square-shaped link 27 and a linear link 29 inserted between the square-shaped plate members 271 and 271, and an intermediate portion where the square-shaped link 27 and the linear link 29 intersect is connected to a connecting pin 31. It was constructed without being pivotally attached. A roller 33 is attached to the front end of each of the dog-legged link 27 and the linear link 29, and the roller 33 rolls within a predetermined range on the upper surface of the valley portion of the U-shaped side frame 21. Of. As shown in FIG. 1, the hydraulic cylinder 11 is on the rear side of the position where the doglegged link 27 and the linear link 29 intersect with each other, and the rod portion 111 can apply a downward pressing force from diagonally above. Therefore, the rod portion 111 is attached to the dogleg 27 and the rear portion of the tubular portion 112 is attached to the linear link 29.

Next, the operation of this embodiment will be described. First, the vehicle mounting table 7 is lowered to the maximum extent, and the tip of the table lower surface 7c of the vehicle mounting table 7 is brought into contact with the parking device installation ground 3, so that the automobile 13 is removed from the parking device installation ground 3. The rear wheel 15 is moved backward on the table upper surface 7a of the vehicle mounting table 7 until it comes into contact with the car stop 17, and then the vehicle is parked. Then, when the hydraulic cylinder 11 is moved to the upward side, the rod portion 111 expands and a pressing force is applied to the doglegged link 27. Then, the pair of link mechanisms 9 start to open around the connecting pin 31, and the rollers 33 attached to the front ends of the pair of linear links 29 respectively move on the upper surface of the side frame body 21 of the support frame 5. The rollers 33 attached to the front ends of the pair of dog-legged links 27 roll on the surface of the cam portion 191 from the front side to the rear side. As a result, the ascending force of the pair of link mechanisms 9 trying to ascend in synchronization also reaches the rollers 33 attached to the front ends of the pair of doglegged links 27, so that the rollers 33 move above the cam portion 191. The front side of the vehicle mounting table 7 is additionally raised by the vertical component of the moving distance from the front side to the rear side. For this reason, the vehicle mounting table 7, which was in the front-lowering state at the beginning of the ascending, gradually rises while relaxing the front-lowering state. Then, when the upward movement of the hydraulic cylinder 11 is continued, the moving distance of the roller 33 becomes longer, so that the vertical component further increases, and the vehicle mounting table 7 eliminates the front lowering state to support the frame. After becoming parallel to the body 5, on the contrary, it continues to rise while strengthening the forward rising state. When the space between the support frame 5 and the vehicle mounting table 7 becomes sufficient for accommodating an automobile to be stored later due to the above-mentioned ascent, the operation of the hydraulic cylinder 11 to the ascending side is stopped. After this, another vehicle is stored in the space. In the vicinity of the front doors of other automobiles, since the link mechanism 9 opens considerably and another space is exposed, the front doors can be opened and closed and the driver can enter and exit without any trouble. When the vehicle 13 parked on the vehicle mounting table 7 is unloaded, first, the vehicle loaded in the space between the support frame 5 and the vehicle mounting table 7 is unloaded, The hydraulic cylinder 11 is moved downward. Then, the rod portion 111 moves into the cylindrical body 112 and a tensile force is applied to the pair of doglegged links 27. For this reason, the pair of link mechanisms 9 start to close in synchronization with the connecting pin 31 as a center, and the rollers 33 attached to the front end portions of the pair of linear links 29 are mounted on the side frame bodies 21 of the support frame 5. Rollers 33 attached to the front ends of the pair of doglegged links 27 on the upper surface roll on the cam portion 191 surface from the rear side to the front side, respectively. As a result, the pair of link mechanisms 9 try to descend synchronously, and the front side of the vehicle mounting table 7 is moved by the vertical component of the moving distance of the roller 33 on the cam portion 191 from the rear side to the front side. To descend further. For this reason, the vehicle mounting table 7, which was in the forward rising state at the beginning of the downward movement, gradually moves down while relaxing the forward rising state. When the lowering operation of the hydraulic cylinder 11 is continued, the moving distance of the roller 33 becomes longer, the vertical component further increases, and the vehicle mounting table eliminates the forward rising state and the supporting frame body is removed. After becoming parallel with 5, it continues to descend while strengthening the forward descending state. In this descending process, the doglegged link 27 is bent in a doglegged shape from the middle portion to the front end, so that the doglegged link 27 and the table lower surface 7c of the vehicle mounting table 7 do not come into contact with each other. .. When the tip of the table lower surface 7c of the vehicle mounting table 7 comes into contact with the parking device installation ground 3 by the descending operation described above, the descending operation of the hydraulic cylinder 11 is stopped. After that, when the vehicle 13 parked on the vehicle mounting table 7 is started, the vehicle 13 sequentially advances on the table upper surface 7a and the inclined surface 7b, and is smoothly delivered to the parking device installation ground 3. It

Although the preferred embodiment of the present invention has been described above in detail, the present invention is not limited to this, and the roller 33 is overlaid in the vicinity of the boundary between the cam portion 191 and the bent portion 192 forming the cam plate 19. It is conceivable to provide means for preventing the roller 33 from rolling and moving from the cam portion 191 to the bending portion 192. Further, rollers 33 provided at the front ends of the dog-legged links 27 and the linear links 29 respectively have a predetermined range (the range is the degree of front rise and fall of the vehicle mounting table 7 and the support frame). 5 is determined by the size of the vehicle accommodated in the space between the vehicle mounting table 7 and the vehicle mounting table 7 and the stroke of the hydraulic cylinder 11 associated with these. When a detection means such as a limit switch is provided at a predetermined position of the device 1, or a key switch for issuing an operation command such as raising, lowering, or an emergency stop of the vehicle mounting table 7 at a position where the driver can easily operate it. The case where a small operation panel using a button is provided and the case where a fall prevention device due to malfunction of the hydraulic cylinder 11 or oil leakage is incorporated is also an embodiment of the present invention. It is intended.

[Effect of the device]

 Since the present invention is configured as described above in detail, it has the following effects. With a very simple overall structure, it is possible to synchronously move up and down the vehicle mounting table on which the vehicle is mounted while performing forward and backward movements. Further, by this, the vehicle mounted on the vehicle mounting table can always move up and down in a stable state. Further, when the vehicle is parked, the vehicle mounting table should be in a forwardly raised state, and a car stop should be provided on the rear side of the vehicle mounting table so that the rear wheels come into contact with the car stop. Therefore, the vehicle can be parked on the vehicle mounting table in an extremely stable state. Furthermore, when the vehicle mounted on the vehicle mounting table is put out or put in, the vehicle mounting table is lowered frontward so that the front end is not set on the ground where the parking device is installed. Since the structure eliminates the step, it is possible to smoothly get on and off the vehicle from the vehicle mounting table without receiving a shock. In addition, since there are no pillar members at the four corners of the parking device, it is easy to enter and leave a car, and the exterior is also functionally beautiful, making it suitable as a parking device to be installed in residential areas, offices, etc.
