Description

[0001]
BACKGROUND OF THE INVENTION
The invention according to this application relates to a sidewalk device for passengers who get on and off from automobiles in a passenger compartment of a mechanical parking device.
[0002]
[Prior art]
The mechanical parking device includes a boarding / alighting room and a storage room, and an automobile is transferred between the two rooms. A partition plate is provided between the two chambers, and the partition plate is opened when the vehicle is transferred. The automobile is transferred by placing the automobile on a pallet and transferring the pallet horizontally between the two chambers.
[0003]
For example, when a vehicle is transferred from the passenger compartment to the storage compartment, first, the automobile is loaded onto the pallet in the passenger compartment and then the vehicle passenger gets off. There is a sidewalk next to the pallet, and those who get off walk on the sidewalk and go out of the boarding room. The sidewalks are usually provided on both sides of the pallet so that you can get off the left or right door of the car. Therefore, a sidewalk is also provided between the pallet and the partition plate. When the automobile is transferred from the passenger compartment to the storage compartment, the partition plate must be opened and the pallet must be transferred horizontally to the storage section of the storage compartment. At this time, it is necessary to retreat the sidewalk between the pallet and the partition plate from the pallet transfer path so that the pallet transfer is not hindered.
[0004]
As a conventional structure for retracting the sidewalk, there is a structure described in, for example, Utility Model Registration No. 2552094. In this structure, a partition plate (elevator gate) with a sidewalk attached to the lower end can be moved up and down by a driving device. According to this structure, the sidewalk can be lifted and lowered from the pallet transfer path by raising and lowering the partition plate.
[0005]
[Problems to be solved by the invention]
The sidewalk supports the weight of passengers and must be strong enough. Therefore, it is manufactured as a can-made product made of steel or the like, and thus the weight increases. In the conventional sidewalk device as described above, since a heavy sidewalk is attached to the lower end of the partition plate, the partition plate itself is required to have sufficient strength to support the load on the sidewalk. For this purpose, the partition plate must be manufactured firmly as a can product made of, for example, a steel plate.
[0006]
On the other hand, the partition plate is a design product that constitutes a part of the wall surface of the passenger compartment, and is required to have less distortion and surface unevenness.
[0007]
However, it is technically difficult and time-consuming to reduce the distortion of the partition plate manufactured as a can product or to reduce the surface irregularities. In order to reduce distortion and unevenness, there is also a method of attaching a decorative panel using a base as in the case of attaching the outer wall of a building. However, even if this method is adopted, the flatness of the base must be good, and it takes time to adjust the entrance and exit of the base.
[0008]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, a sidewalk device for passengers of a mechanical parking device according to the present invention is such that an automobile is placed on a pallet in a passenger boarding room, and the pallet is placed in and out of a storage room from the passenger room. In a mechanical parking device that transfers the automobile to the loading / unloading section by moving horizontally toward the section, a partition plate provided so as to be able to be lifted and lowered between the passenger compartment and the loading / unloading section; An elevating member having a sidewalk part, and a drive device for raising and lowering the elevating member, the sidewalk part being located between the pallet and the partition plate when the pallet is on the boarding / exiting room side, When the elevating member is raised from the lower limit position by the driving device, the elevating member abuts on the lower end of the partition plate, and the partition plate is lifted by the elevating member (Claim 1).
[0009]
The above-mentioned boarding device for passengers may be configured to include a carrying portion for carrying the partition plate when the elevating member is at the lower limit position (Claim 2), and further, a plurality of the partition plates may be provided. And the supporting part may be configured to support a plurality of partition plates at different heights (Claim 3).
[0010]
In the above-mentioned pedestrian sidewalk device, the upper end of the partition plate may be rotatably supported, and a substantially intermediate portion in the vertical direction of the partition plate may be formed as a bent portion.
[0011]
According to these configurations, the partition plate and the sidewalk are separated from each other, and no load other than its own weight acts on the partition plate. Therefore, the partition plate is not required to have enough strength to support the sidewalk, and the degree of freedom in designing the partition plate is improved. Thereby, for example, the thickness of the partition plate can be designed to be small. Further, various materials and processing methods can be employed in the production of the partition plate. Further, the weight of the sidewalk is not limited by the strength of the partition plate, and a sidewalk with sufficient strength can be designed.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described with reference to the drawings.

It is done.
[0015]
The pedestrian sidewalk device 1 is mainly composed of an elevating member 2, a driving device 5, and two partition plates 7 and 8.
[0016]
The elevating member 2 includes a sidewalk part 3 and a support member 4. The sidewalk part 3 is attached on the horizontal arm part 4 a of the support member 4. Since the sidewalk 3 is required to have sufficient strength to safely support the load of passengers from the automobile 10, it is manufactured by bending a steel plate. Therefore, the weight of the sidewalk part 3 itself is large. The support member 4 has a steel frame structure and has sufficient strength to support the heavy sidewalk 3. In FIGS. 1 to 3, the pallet P is on the side of the passenger compartment S <b> 1, and the sidewalk part 3 must be located below the passengers getting on and off from the automobile 10. For this reason, the sidewalk 3 is supported by the support member 4 so as to be positioned between the pallet P and the partition plates 7 and 8. The support member 4 includes guide rollers 4d at both ends. The guide rollers 4d are gently fitted into guide grooves 14 provided on both sides of the support member 4 and extending in the vertical direction. The support member 4 is guided by the guide groove 14 and can be moved up and down in the vertical direction.
[0017]
The drive device 5 is provided above the support member 4. The driving device 5 mainly includes a pulley 5a, a shaft 5b serving as a rotation center of the pulley 5a, a wire 5c spanned over the pulley 5a, a counterweight 5d, and an electric motor (not shown). One end of the wire 5c is fixed to the support member 4, and the other end is fixed to the counterweight 5d. The counterweight 5d is for balancing the load with the support member 4 and the like. The drive shaft of the electric motor is connected to the shaft 5b through a reduction gear, and the pulley 5a can be rotated by rotation control of the electric motor. The elevating member 2 can be raised and lowered by driving and controlling the driving device 5. In addition, in FIGS. 1-3, the raising / lowering member 2 exists in the minimum position of the raising / lowering possible range.
[0018]
The partition plates 7 and 8 are provided between the passenger compartment S1 and the entrance / exit part S2. The partition plates 7 and 8 are provided with guides 7a and 8a having a U-shaped cross section at both ends. The guides 7a and 8a are loosely fitted with guide rails 17 and 18 provided on both sides of the partition plates 7 and 8 and extending in the vertical direction. Guided by the guide rails 17 and 18, the partition plates 7 and 8 can be moved up and down in the vertical direction. Rubber legs 7b, 8b are attached in the vicinity of both ends of the lower end surfaces of the partition plates 7, 8. A carrier 20 is erected inside the guide rails 17 and 18. Two step surfaces 27 and 28 are formed on the carrier 20 at different height positions. The rubber legs 7b and 8b of the partition plates 7 and 8 are in contact with the step surfaces 27 and 28 of the carrying part 20, respectively. Thus, the two partition plates 7 and 8 are supported at different height positions. The load of the partition plate 7 acts on the step surface 27 via the rubber leg 7b, and the load of the partition plate 8 acts on the step surface 28 via the rubber leg 8b.
[0019]
FIG. 4 is a perspective view for illustrating the positional relationship between the elevating / lowering member 2 and the partition plates 7 and 8 when the elevating / lowering member 2 is at the lower limit position of the ascending / descending range as shown in FIGS. The elevating member 2 and the partition plates 7 and 8 are separated from each other, and the load of the partition plates 7 and 8 is carried by the carrying portion 20. Therefore, a gap is generated between the lower end surfaces of the partition plates 7 and 8 and the elevating member 2. That is, the load of the partition plates 7 and 8 is not acting on the elevating member 2 at all. Further, the load of the elevating member 2 does not act on the partition plates 7 and 8 at all. When the elevating member 2 is lifted by the drive device from the lower limit position of the elevating and lowering range, the lower end surfaces of the partition plates 7 and 8 are in contact with the upper surface of the horizontal arm portion 4a of the support member 4 in order, and the abutting portions 4b and 4c. The load of the partition plates 7 and 8 will act on this.
[0020]
FIG. 5 is a vertical cross-sectional view of the pedestrian sidewalk apparatus 1 in a state where the elevating member 2 is raised by the driving device 5 and the partition plate 7 is lifted by the elevating member 2. At this time, the point of application of the load on the partition plate 7 has shifted from the stepped surface 27 of the carrying part 20 to the contact part 4 b of the support member 4. No load other than its own weight acts on the partition plate 7. In addition, the sidewalk part 3 rises with the raising of the supporting member 4 and has already retreated from the transfer path D of the pallet P.
[0021]
FIG. 6 is a vertical cross-sectional view of the passenger's sidewalk apparatus 1 in a state where the elevating member 2 is further raised by the driving device 5 and the partition plate 7 and the partition plate 8 are lifted by the elevating member 2. At this time, the point of application of the load on the partition plate 8 has shifted from the stepped surface 28 of the carrying part 20 to the contact part 4 c of the support member 4. No load other than its own weight acts on the partition plate 8. And the raising / lowering member 2 is further raised from the state of FIG. 6, and the sidewalk part 3 and the support member 4 become the height which does not prevent the transfer of the motor vehicle 10 from the passenger compartment S1 to the entrance / exit part S2. Then, the pallet P is transferred to the loading / unloading unit S2. Thereafter, when closing the partition plates 7 and 8, the elevating member 2 is lowered by the drive device 5, and the partition plates 8 and 7 are sequentially deposited on the step surfaces 28 and 27 of the carrier 20, and finally the elevating member 2 is set to the lower limit. Return to position.
[0022]
In the sidewalk device 1 for passengers shown in FIGS. 1 to 6, the two partition plates 7 and 8 are used to partition the passenger compartment S1 and the entry / exit section S2, but the number of partition plates is not limited to two. It may be three or more, or only one.
[0023]
Moreover, in the sidewalk device 1 for passengers of FIGS. 1 to 6, the sidewalk 3 is provided at a position corresponding to the partition plates 7 and 8, but the position where the sidewalk 3 is provided must be limited to such a position. There is no. For example, it can be provided at an arbitrary position with respect to the partition plates 7 and 8 in the longitudinal direction of the pallet P (direction orthogonal to the paper surface in FIG. 1). This can be done because the sidewalk 3 is formed on a separate member (elevating member 2) separated from the partition plates 7 and 8. In order to avoid placing a member for supporting the sidewalk in the transfer path of the pallet P and simplify the structure of the mechanical parking device, the sidewalk portion 3 is moved from the position corresponding to the partition plates 7 and 8. It can also be shifted. Moreover, although the example which uses the pulley 5a and the wire 5c for the drive device 5 was shown, it can replace with these and can also use a sprocket and a chain, for example.
[0024]
FIG. 7 is a diagram illustrating another configuration example of the elevating member. In FIGS. 1-6, although the elevating member 2 comprised by attaching the sidewalk part 3 manufactured by bending a steel plate on the horizontal arm part 4a of the support member 4 of a steel frame structure was shown, You may comprise a raising / lowering member by integrally forming a support member. FIG. 7 is a perspective view of such a lifting member 52. The elevating member 52 has a horizontal plate 52 a, and a part of the upper surface of the horizontal plate 52 a becomes a sidewalk 53. The elevating member 52 is not functionally different from the elevating member 2 shown in FIGS.
[0025]
FIG. 8 is a longitudinal sectional view of a sidewalk device 51 for passengers of a mechanical parking device according to another embodiment of the present invention. Unlike the pedestrian sidewalk device 1 shown in FIGS. 1 to 6, the pedestrian sidewalk device 51 includes an elevating member 52 shown in FIG. Therefore, a part of the upper surface of the horizontal plate 52 a of the elevating member 52 becomes the sidewalk part 53. The elevating member 52 also includes guide rollers 4d at both ends, and the guide rollers 4d are gently fitted into the guide grooves 14 provided on both sides of the elevating member 52 and extending in the vertical direction. Guided by the guide groove 14, the elevating member 52 can be raised and lowered in the vertical direction.
[0026]
The structure of the drive device 5 for raising and lowering the elevating member 52 is the same as that of the drive device 5 shown in FIGS.
[0027]
Moreover, although the boarding device 1 for passengers of FIGS. 1-6 was equipped with the two partition plates 7 and 8, the sidewalk apparatus 51 for passengers is different from this, and the bending part 59c is the substantially intermediate part of the up-down direction. A partition plate 59 having The bent portion means a portion formed to be freely bent. In this embodiment, the bent portion 59c is constituted by a hinge connecting the upper plate 59a and the lower plate 59b that constitute the partition plate 59. The upper end of the partition plate 59, that is, the upper end of the upper plate 59a is attached to the ceiling portion Sc of the passenger compartment S1, and the attachment structure is a hinged structure by a hinge 59e. As described above, the upper end of the partition plate 59 is rotatably supported. Guide rollers 59d are attached in the vicinity of the lower ends of both side end surfaces of the lower plate 59b of the partition plate 59, and the guide rollers 59d are loosely formed in guide grooves 60 provided on both sides of the partition plate 59 and extending in the vertical direction. It is inset. Since the guide roller 59d is guided to the guide groove 60, the movement direction thereof is restricted to the vertical direction.
[0028]
In the state of FIG. 8, the elevating member 52 is at the lower limit position of the elevating range, and a gap is generated between the upper surface of the horizontal plate 52a and the lower end of the lower plate 59b. Therefore, the load of the partition plate 59 is not acting on the elevating member 52 at all. Further, the load of the elevating member 52 does not act on the partition plate 59 at all.
[0029]
FIG. 9 is a longitudinal sectional view showing a state where the elevating member 52 is raised by the driving device 5 and the elevating member 52 lifts the partition plate 59. FIG. 10 is a perspective view for clearly showing the relationship between the elevating member 52 and the partition plate 59 at this time. The elevating member 52 lifts the lower end portion of the partition plate 59, and the partition plate 59 is bent at the bent portion 59c. The load of the partition plate 59 acts on the upper surface of the horizontal plate 52 a of the elevating member 52. No load other than its own weight acts on the partition plate 59.
[0030]
The lift member 52 is further raised from the state shown in FIG. 9, and the lift member 52 has reached a height that does not hinder the transfer of the automobile 10 from the passenger compartment S1 to the loading / unloading section S2. Transferred to S2. Thereafter, when the partition plate 59 is closed, the elevating member 52 is lowered by the driving device 5. When the elevating member 52 returns to the lower limit position, the partition plate 59 is in the same state as in FIG.
[0031]
