    Next, the present invention will be described in detail based on the illustrated embodiment.

  FIGS. 1-7 shows one Embodiment of the two-stage parking apparatus 1 of this invention, Comprising: The ground 3 is excavated and the underground pit 2 made from reinforced concrete which continues in a horizontal direction (left-right direction) is shown. A lower pallet 4 is provided in the underground pit 2 with a space in the lateral direction, and an upper pallet 5 is provided on the ground portion directly above each lower pallet 4. In the two-stage parking apparatus 1 of the present invention, in order to reduce the excavation amount of the ground 3, the pit depth d on the rear side of the underground pit 2 is set to the underground pit 41 of the conventional two-stage parking apparatus 40 shown in FIG. For example, the guide roller 13 is shallower than the pit depth D on the rear side by about ½ to す る of the moving amount by which the guide roller 13 moves upward.

In the underground pit 2, the boarding side (front side) is slightly deeper than the rear side. On the rear side of the underground pit 2, support columns 7 provided with guide grooves 6 in the vertical direction are provided in the horizontal direction at intervals in the horizontal direction. The support column 7 is made of a steel material having an H-shaped cross section such as an H-shaped steel, and includes a base plate fixed to the lower end portion of the support column 7 by welding or the like. The base plate is an anchor material (illustrated) at the bottom of the underground pit 2. Is omitted). Each support column 7 is installed such that a groove formed by a pair of flanges and a web faces each other at an interval in the lateral direction (see FIG. 7).
A support member 8 made of an H-shaped steel beam is fixed to each support column 7 by welding or the like at the upper end of each support column 7 spaced in the horizontal direction. The support member 8 includes a front portion of the underground pit 2. A set of upper brackets 9 projecting toward the side are provided at intervals in the left-right direction, and each upper bracket 9 is provided with a horizontal shaft 10 formed of a horizontal pin or the like (FIGS. 1 to 1). 3).

A steel lower pallet 4 is arranged between a pair of support columns 7 spaced in the lateral direction, and lower brackets 12 are fixed to both sides of the lower pallet 4 in the width direction. The guide rollers 13 are respectively guided along the vertical guide grooves 6 of the support columns 7 and are fitted so as to be movable up and down by rolling in the vertical direction.
The guide roller 13 may be, for example, a guide roller that does not include a flange. However, it is desirable that the guide roller 13 is a guide roller with a flange because the lateral pallet 4 can be prevented from being shaken.

Each of the rear arms 11 on both sides in the width direction of the upper pallet 5 disposed above the lower pallet 4 is connected to the upper bracket 9 spaced in the lateral direction by a horizontal shaft 10. A telescopic drive device 15 such as a hydraulic (hydraulic) type is connected to the left and right sides of the front part of the upper pallet 5 and each base member 14 fixed on the floor of the underground pit 2 at a lateral interval. Yes. The upper end portion of the telescopic drive device 15 is connected to the upper pallet 5 in the vicinity of the connecting portion of the upper end portion of the front connecting member 16 described later.
Further, the left and right sides of the front portion of the upper pallet 5 and the left and right sides of the front portion of the lower pallet 4 are respectively a front connecting member 16 made of a strip such as a steel wire rope or a steel connecting rod. A horizontal axis is pivotally connected.
Further, the left and right sides of the rear portion of the upper pallet 5 and the left and right sides of the rear portion of the lower pallet 4 are respectively defined by a rear connecting member 17 made of a strip of steel wire rope or a steel connecting rod and a horizontal axis. It is connected so that it can rotate.

Each rear connecting member 17 is longer than each front connecting member 16, and the rear connecting member 17 and the front connecting member 16 are arranged in an inclined state so as to approach toward the upper part.
The both sides of the rear part of the lower pallet 4 and the both sides of the rear part of the upper pallet 5 are connected by the respective rear connecting members 17 at appropriate positions (positions on the rear side of the telescopic drive device 15). As the pallet 5 rotates, the rear part of the lower pallet 4 can be raised and lowered along the guide roller 13 and the guide groove 6 behind the lower pallet 4.
Therefore, the upper pallet 5 can be turned up and down around the upper horizontal shaft 10 by extending and retracting the telescopic drive device 15. In addition, the rear end portion of the lower pallet 4 connected to the upper pallet 5 by the connecting members 16 and 17 is guided along the guide groove 6 of the support column 7 as the upper pallet 5 is raised, and the guide is moved up and down. It can be raised together with the roller 13. Further, by extending and retracting the telescopic drive device 15, the lower pallet 4 connected by the connecting members 16 and 17 can be rotated up and down around the horizontal center axis of the guide roller 13. Yes.

  Each of the connecting members 16 and 17 comprises a strip such as a steel wire rope or a steel rod, and both ends of the connecting member are connected by a horizontal axis. Each of the connecting members 16 and 17 is a tension type connecting member that pulls up the lower pallet 4 by a tensile force. Further, by using the connecting members 16 and 17 as connecting rods, the connection between the upper pallet 5 and the lower pallet 4 is ensured, and since the rod is used compared to the wire rope, the rigidity is high and the lower pallet The rigidity of the frame structure by the pallet 4, the upper pallet 5, and the connecting members 16 and 17 made up of the connecting rods is increased, and the side sway of the upper pallet 5 is small as compared with the case of using the connecting member by the wire rope. In addition, you may make it use the rod-shaped rod which consists of rod-shaped members, such as a shape steel, as a connection material.

Since the rear end portion of the upper pallet 5 is rotatable about the upper horizontal axis 10 of the upper bracket 9 fixed to the support member 8 provided on the upper portion of the support column 7 or on the upper portion of the support column, it can be expanded and contracted. When the upper drive pallet 5 is turned up and down and turned up and down by expanding and contracting the drive unit 15, the inclination angle θb1 of the upper pallet 5 with respect to the horizontal plane can be made smaller than the conventional case. As compared with the case of the conventional two-stage parking apparatus 40 shown in FIG.
Further, the lower pallet 4 connected to the upper pallet 5 by the connecting members 16 and 17 rotates (swings) while the rear end of the lower pallet 4 ascends with the guide roller 13 as described above. The inclination angle θb2 of the lower pallet 4 with respect to the horizontal plane can be made gentler than the inclination angles θa1 and θa2 in the case of the conventional two-stage parking apparatus 40 shown in FIG. Driving operation is facilitated by reducing the amount.
In the state where the lower pallet 4 is stored in the underground pit 2 so that the front side of the lower pallet 4 is lifted, the front end portion (tip portion) of the lower pallet 4 enters the exit side of the underground pit 2. It is adjusted to the level of the surface (see FIG. 2). In this state, the automobile on the lower pallet 4 in the underground pit 2 climbs toward the exit side and enters and exits the lower pallet 4 inclined.
Further, in a state where the upper pallet 5 on the ground side is arranged in an inclined state so that the front side thereof is lowered, the front end portion (tip portion) of the upper pallet 5 is landed substantially at the level of the boarding surface on the exit side. It is assumed that In this state, the vehicle on the upper pallet 5 on the ground side enters and exits the upper pallet 5 inclined downward toward the exit side.

In the underground pit 2, a lower fixed sidewalk 20 is provided at substantially the same level as the lower pallet 4 in a state where the lower pallet 4 is stored, and the lower fixed sidewalk 20 is fixed before and after being fixed to the underground pit floor 19. Are fixed to the columns 27 and 7.
Further, upper fixed sidewalks 21 are provided on both sides in the width direction of each upper pallet 5, and handrails are omitted between the upper pallets 5 adjacent in the left-right direction, so that the space S is increased between the vehicles 23. The door of each adjacent vehicle can be opened greatly. In addition, on the upper pallet 5 side, handrails 22 are provided only at the outermost ends in the left-right direction, thereby simplifying the structure of the two-stage parking apparatus 1 and reducing the weight compared to the conventional two-stage parking apparatus 40. I try to figure it out.

  As described above, by installing the hinge pin position of the upper pallet from the pit floor surface position to the upper part of the rear column 7 as in the prior art, the inclination angle with respect to the horizontal plane when the upper pallet 5 and the lower pallet 4 are loaded and unloaded. Can be made smaller than in the case of the conventional two-stage parking apparatus shown in FIG.

When the owner of the vehicle 23 of the lower pallet 4 enters and exits, the upper pallet 5 is entered from the state in which the upper pallet is lifted upwards and is lifted upward at the end of the delivery, and is lowered to the entry surface so as to block the underground pit 2 By operating the control panel 24, the space between the adjacent upper pallets 5 is always closed, so that the handrails 34 on both sides between the upper pallets 5 are omitted as in the prior art. The structure of the two-stage parking apparatus 1 is simplified by providing the handrails 22 only on both outermost sides.
Thus, since the state where all the upper pallets 5 connected in the left-right direction block the underground pit 2 is the final steady state, there is no need for a handrail between the pallets. The door can be opened widely, making it easy to get on and off, especially when it is raining, allowing a large space for opening and closing the umbrella, making it easier to operate, compared to the case where the space of the conventional two-stage parking system is small Inconvenience during rain can be eliminated. In addition, since the lower pallet 4 also has a sidewalk 20 between adjacent ones and does not require a handrail, the door of the vehicle 23 can be greatly opened.

  In addition, the passage when the lower pallet enters and leaves the underground pit 2 is a fixed sidewalk between adjacent pallets according to the inclination of the pallet, and the fixed pedestrian 20 is not integrated between the lower pallets for each pallet. It is said. For this reason, it is set as the form which does not need to install the handrail between adjacent lower pallets.

As described above, according to the present invention, the lower pallet 4 is provided in the underground pit 2, and the upper pallet 5 on the ground side is connected to the lower pallet 4 with the connecting members 16 and 17 at an interval. 5 by extending the telescopic drive device 15 connected to the middle part of the pit 5 and the inner floor of the underground pit to rotate the upper pallet 5 to raise the front end side of the upper pallet 5 and to move the front end of the lower pallet 4 It is a two-stage parking device that raises the side, and columns with vertical guide grooves at the rear part in the underground pit are erected at intervals in the lateral direction, at the rear end part of the lower pallet A guide roller is provided, and the guide roller is fitted in the guide groove of the support column so as to be movable up and down, and the rear part of the lower pallet is installed so as to be movable up and down together with the guide roller by a rear connecting member 17. In this case, the rear end of the upper pallet is connected to a bracket provided on an upper portion of the support column or a support member installed over the upper portion of the support column so as to be rotatable by a horizontal axis. In comparison, the position of the upper pallet and the lower pallet can be adjusted so that the inclination angle is reduced (for example, from the conventional inclination angle of about 10 ° to an inclination angle of about 7 ° to 8 °). The effect that the driver can feel fear and can eliminate the fear of driving operation such as an abnormal accelerator operation can be obtained.
In addition, since the rear part of the lower pallet can be lifted, the amount of ground excavation when excavating the ground to form an underground pit can be reduced as compared with the conventional case.
Further, according to the present invention, a guide roller is provided in the rear end portion of the lower pallet with a space in the lateral direction, and each guide roller can be moved up and down in the vertical guide groove of the support column spaced in the lateral direction. Therefore, it is possible to increase the rear side of the lower pallet with a simple structure and reduce the inclination angle of the lower pallet with respect to the horizontal plane.
Further, according to the present invention, since the support column is a steel material having an H-shaped cross section, it can be a support column having a guide groove for guiding the guide roller with a simple structure, and an inexpensive support column with a guide groove. And the like.
Further, according to the present invention, the floor portion of the underground pit is a floor portion that is inclined so that the front side on the exit side is deeper than the rear side, so that the underground pit type two-stage type with less ground excavation amount The effect that it can be set as a parking apparatus is acquired.
Further, according to the present invention, the connecting material is composed of a strip or steel rod such as a steel wire rope, and both ends of the connecting material are connected by the horizontal axis, so the lower pallet is connected with a simple structure. Thus, such an effect that the structure can be lifted can be obtained.

  When carrying out the present invention, an upper bracket may be provided on the upper part of the rear support column 7 so that the bracket provided on the rear end portion or the rear end portion of the upper pallet 5 can be pivotally connected to the horizontal axis. .
