Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a multi-level parking system, and in particular, to a pit excavated from the ground surface, a frame is provided in which pallets forming a vehicle parking surface are vertically spaced apart and supported in two stages, an upper and a lower stage. This invention relates to an improvement of a multi-story parking device in which a frame is driven up and down.

In general, this type of multilevel parking system consists of pallets (plate-like structures that form the vehicle parking surface) that are spaced apart in the upper and lower directions so as to form multiple stages, with predetermined spacing and positional relationships in the vertical direction. It is usually formed by rigidly connecting and fixing with a frame, and one constituent block formed in this way can be driven up and down in the vertical direction with respect to a pit excavated from the ground surface. It is known as having the feature that by making any stepped section stand still at the same height as the ground surface, vehicles can enter and exit regardless of whether or not vehicles are parked on other stepped sections. There is.

In addition, in such a multilevel parking system, for example, only the upper pallet is fixed to the frame, and the lower pallet is suspended from the upper pallet by a chain or the like, and after the lower pallet has landed on the bottom of the pit, the upper pallet is further fixed to the frame. By adopting a method in which the pallets can be lowered, the required depth of pit excavation can be reduced, or by tilting the front side of the upper pallet (the side where vehicles enter and exit), the upper and lower pallets can be moved up and down. The pit excavation depth was also made shallower by making the interval partially variable.
It has been proposed in Publication No. 56-143344, etc.

By the way, in order to raise and lower such a frame, a hydraulic cylinder device as a drive device is usually interposed between the frame and the bottom of the pit, and
A lifting guide mechanism is attached to guide the raising and lowering of the frame, but since these support the heavy frame loaded with a vehicle and raise and lower it, they are not structurally strong or It is also necessary that the hydraulic cylinder output for lifting and lowering the vehicle be large.

The present invention was made on the above premise with the aim of simplifying the structure and reducing the cost of the lifting drive and guide mechanism, and furthermore, by extremely simple changes in the structure, the frame of the upper pallet The purpose of the present invention is to provide a multilevel parking device that can tilt as it goes up and down.

That is, the origin of the present invention is that the direction of output action of the hydraulic cylinder device for supporting the frame and driving it up and down is vertically upward, opposite to the direction in which the weight of the frame (vehicle) is applied. This is most desirable in terms of efficiency, and due to the structure of the multilevel parking system, the arrangement of the hydraulic cylinder device is not on the side where vehicles enter and exit, but on the rear side on the opposite side, so that it is spaced in terms of volume and space between vehicles entering and exiting. This is because it was considered desirable from the standpoint of preventing interference.

This is achieved by arranging and arranging the hydraulic cylinder device on the rear end of the pallet of the frame, opposite to the side where the vehicle enters and exits, and by providing it vertically between the pit bottom and the frame. be done. However, as a result of this, the weight support of the frame by this device is biased towards the rear side, so in the present invention, corresponding to the arrangement of such a hydraulic cylinder device, it is necessary to support the frame and keep it parallel in the vertical direction. A scissor-type lifting and lowering guide mechanism of a crossed two-leg opening/closing motion type that can be moved up and down while maintaining the position is interposed between the lower edge of the frame and the bottom of the pit.

In addition, in a multi-story parking system equipped with this type of scissor-type elevating guide mechanism and a vertical hydraulic cylinder device arranged at the rear of the frame, the legs of the scissor-type mechanism that are pivotally connected to the lower edge of the frame are If the upper end is viewed from the lower end of the bottom side of the pit, it can be considered that the upper end rotates about this center axis, and the upper end rotates at the pivot point between the upper end and the frame, or further from this pivot point. The leg extending portion extending in the lengthwise direction of the leg rotates with respect to the frame as the frame moves up and down (i.e., the leg opening/closing movement of the scissor-type mechanism). In the latter case, relative displacement occurs in the front-back direction, and in the latter (leg extension part), relative displacement occurs in the vertical and front-back directions.

Therefore, by utilizing such relative displacement, if the front side of the upper pallet located at the top of the frame is tilted with respect to the lower pallet located at the bottom of the frame, the pit excavation can be easily performed. There is also the advantage that it is possible to easily realize a practically extremely useful configuration in which the parking area is made shallow, and it is an object of the present invention to provide a multilevel parking device having such an advantage.

Therefore, the present invention can be understood as a multi-level parking device that typically has the following characteristics. In other words, an upper pallet and a lower pallet for vehicle parking are separately supported in two upper and lower stages, and a frame is arranged so as to be able to be raised and lowered relative to the excavation pit, and the opposite side is used for vehicles to enter and exit from these pallets. At the rear end position of
A hydraulic cylinder device is provided in a vertical position between a lower frame portion supporting the lower pallet of the frame frame and the bottom bottom of the pit and drives the frame up and down; A scissor-type elevating guide mechanism is provided between the upper and lower pallets to guide vertical translation of the frame by opening and closing movements of two intersecting legs. This is a multi-story parking device having a structure in which the parts are fixedly connected at at least four points in the front, back, left and right to a lower frame part forming a pedestal for the lower pallet, thereby forming a rigid structure as a whole.

Still further, the present invention provides that the upper frame portion of the frame frame serves as a cradle for the upper pallet and is pivotally connected to the lower frame portion that serves as a cradle for the lower pallet on the rear end side, so that the front end side thereof can be vertically moved. The upper frame is swingably provided, and the front end side of the upper frame is connected to the upper end of one of the scissor-type legs or its extension via an inclined link so as to be able to support weight. It is also suitably realized as

The present invention will be described below based on embodiments shown in the drawings.

Example 1 In FIGS. 1 and 2, 1 is the ground surface, 2 is the excavated pit, and 3 is the bottom of the pit.

Reference numeral 4 denotes a base structure fixed to the bottom bottom 3 of the pit, in which a pair of steel materials, etc., which are placed and fixed in parallel to the left and right positions of vehicles entering and exiting the pallet, which will be described later, are supported by reinforcing materials. It is formed by connecting the two.

5 shows the entire frame for supporting the upper and lower pallets 10 and 11. In order to support the lower pallet 10, a pair of frame members extending on both left and right sides of the vehicle are supported by appropriate reinforcing materials. A lower frame part 6 that is connected and fixed to form a pedestal, a vertical frame part 7 erected at the rear of this lower frame part 6 (left side in the figure), and an upper stage provided similarly to the lower frame part 6. It consists of an upper frame part 8 as a pallet holder, and the upper frame part 8 is fixedly connected to the upper end of the vertical frame part 7, and a bar-shaped part constructed between it and the lower frame part 6 on the front side thereof. It is fixedly connected to the upper end of the support connecting member 9, and is integrally structured so as to maintain a constant vertical distance from the lower frame part 6 by fixed support at four points on the front, back, left and right sides as a whole.

And upper pallet 11 and lower pallet 1
0 is supported by being placed on the upper frame part 8 and the lower frame part 6, respectively.

The frame 5 having such a structure is kept in a horizontal state by a scissor-type lifting guide mechanism connected and interposed between the lower edge of the frame (i.e., the lower frame part) and the lower base 4. It is provided so that it can be moved up and down with respect to the pit 2.

This scissor-type elevating guide mechanism is arranged in a pair on the left and right sides of the vehicle, and has two legs 13, 1 that are combined to be able to open and close a central shaft 12 at the intersection center.
4 are directly pivoted to the lower base 4 or the frame lower frame 6 at the front end of the pit (the right end in the figure), and the lower base 4 or the lower frame 6 at the rear end (the left end in the figure), respectively. It is connected to the lower frame portion 6 of the frame via sliding mechanisms 15 and 16.

The sliding mechanisms 15 and 16 consist of a combination of guide rails and rollers, and the rollers rotate and slide along the guide rails that extend in the front and back direction of the frame 5 as the two legs 13 and 14 open and close. , for example leg 1
3, the upper end pivotally connected to the roller is allowed to rotate about the lower end pivotally connected to the base 4.

Of course, when connecting the two legs 13 and 14 to the base 4 or the frame 5 directly or through a sliding mechanism, the front and rear positions (left and right in the figure) may be reversed. Of course.

Reference numeral 17 denotes a hydraulic cylinder device provided vertically in a pair on the left and right sides at the rear position of the frame 5, and the cylinder body 18 is located at its lower end (i.e. near the opening) with the opening facing downward.
However, a shaft 21 is connected to the lower edge of the frame 5, in this embodiment, to the lower end of the vertical frame portion 7 via a bracket 20.
The closed end extends upwardly. The piston rod 19, which slides in and out relative to the cylinder body 18, is pivotally fixed at its lower end to the shaft 22 of the lower base 4, and its upper end is tightly fitted into the opening of the cylinder body. It is designed so that it can be slid in and out.

Although the hydraulic piping to the hydraulic cylinder device 17 is not shown in the figure, when the hydraulic pressure is transmitted into the cylinder body, the piston rod 19 remains as it is and does not move up or down; 18 moves upward. On the other hand, when the hydraulic pressure is removed, the cylinder body 18 moves downward.

When the hydraulic pressure inside the cylinder body 18 is removed from the state shown in FIG.
8, the scissor-type guide mechanism gradually folds up so as to crush the legs 13 and 14, and the frame 5 descends while maintaining a state parallel to the base, and stops when it reaches the lowest point (second (see figure).
Therefore, vehicles can move in and out of the upper pallet 11 in this state.

Next, by force-feeding hydraulic pressure to the cylinder body 18, the frame 5 rises while maintaining a parallel state, contrary to the above, and is stopped when it reaches its highest point. It remains stationary in position (see Figure 1). In this state, vehicles can enter and exit the space above the lower pallet 10.

According to the above configuration, the weight of the vehicle acting on the frame 5 is transferred to the scissor-type elevating guide mechanism and the hydraulic cylinder device 17, and can be stably supported using relatively simple structural members. In addition, when the frame is lowered, the second
As you can see from the figure, there are no protruding parts to the ground,
It is advantageous in terms of aesthetics and safety management.

Although the hydraulic cylinder device of the present invention is not limited to this example, in particular, as shown in the figure, the piston rod 19 is slidably supported in and out of the lower end opening of the cylinder body 18, and as shown in the figure, the piston rod 19 is slidably supported in the lower end opening of the cylinder body 18. If the lower end of the body 18 is to be connected and supported by the frame 5, the buckling strength of the hydraulic cylinder device 17 can be considered in the range of the column height approximately corresponding to the length of the piston rod 19, and its small diameter There is an advantage in that it can also be used for

Although not shown in the figure, the cylinder body 18
For example, in view of the fact that the cylinder body 18 is movable, the hydraulic piping to the piston rod 18 may be connected using a flexible tube. Preferably, a hydraulic pressure is transmitted through the flow path.

This is because the buckling strength of the hollow annular member is not significantly lower than that of a solid member having the same outer diameter.

It goes without saying that a locking mechanism for mechanically ensuring that the frame 5 stops at its highest point may be provided as appropriate.

Embodiment 2 In FIGS. 3 and 4, the upper frame part of the frame is always kept relative to the lower frame part by utilizing the feature that the two intersecting legs of the scissor-type guide mechanism move to open and close the legs. Instead of maintaining a constant distance in the vertical direction, the frame is constructed so that the front part tilts slightly as the entire frame moves up and down, thereby reducing the amount of pit excavation. This figure shows a more desirable embodiment of the present invention in which the axial length of the device is shortened so that the length of the column on which the column compressive load acts can be further shortened.

This will be explained below, as shown in Figures 3 and 4.
Embodiment 2 shown in the figure is almost the same as Embodiment 2, except that the structure of the elevating guide mechanism and the frame is slightly different.
00 is added and the explanation is kept within the necessary range.

That is, in the second embodiment, the two legs 11 of the guide mechanism
3 and 114 are directly pivotally connected to the lower frame part 106 or the base 104 at the rear end (hinges that cannot be moved but can be rotated) and are slidable at the front end, contrary to the case of Embodiment 1. It is pivotally connected to the lower frame portion 106 or the base 104 via mechanisms 115 and 116. A rod-shaped support connecting member 109 that pairs with the vertical frame portion 107 and connects the lower frame portion 106 and the upper frame portion 108 in the vertical direction has an upper end pivotally attached to the upper frame portion 108 with a hinge, and the other side The lower end is pivotally connected to an extending end 114b that slightly extends in the longitudinal direction of the leg from a portion 114a of the sliding mechanism 115 of the leg 114 that is connected to a roller (not shown).

In this way, as can be understood from the illustrations in FIGS. 3 and 4, the rod-shaped support connecting member 109
The lower end support point (that is, 114b) causes a slight vertical displacement with respect to the lower frame portion 106 in response to the opening/closing operation of the two legs 113 and 114 forming the scissor-type lifting guide mechanism, and this displacement results in Upper frame part 10
This causes a movement in which the front side of the frame 8 is tilted relative to the lower frame portion 106.

Note that the lower end of the rod-shaped support connection member 109 is connected to the leg 114.
If the rod-shaped support connection member is pivoted to the pivot connection portion with the sliding mechanism 115 instead of the extending end of the frame, the displacement as the frame moves up and down occurs only in the front-rear direction. A certain degree of tilting of the upper frame portion 108 can be obtained by changing the tilting posture of the upper frame portion 109.

As shown in the drawings explaining each of the above embodiments, the front end portion of the upper pallet supported by the upper frame is inclined slightly forward and downward from the vehicle mounting surface (as shown in the drawings). 11a, 111a), this is for the purpose of ensuring smooth entry and exit of vehicles into and out of the upper pallet, but furthermore, in the case of the tilting type of upper frame (Example 2), this configuration reduces the amount of pit excavation. This has the advantage that it also contributes to reduction.
That is, considering the dimensions L and l shown in Fig. 3,
The standard for the entry and exit of people should be L rather than L, and the fact that the front part of the upper pallet is slanted as described above means that the vehicle mounting surface is on the ground level in the state shown in Figure 4. This means that it can be made slightly higher than 101, which is effective in reducing the amount of pit excavation.

As described above, the multilevel parking system according to the present invention has good output efficiency and a simple structure by combining a scissor-type lifting guide mechanism and a vertical hydraulic cylinder device. Its usefulness is enormous.
