Description

[Technical Field]

[0001] The present disclosure relates to parking pallets and mechanical parking lots. [Background technology]

[0002] Patent Document 1 discloses a plate (pallet) to be installed in a multi-story parking garage. The surface of the plate is embossed with unevenness to prevent slipping. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 09-302971 Summary of the Invention [Problem to be solved by the invention]

[0004] Generally, pallets that are embossed to prevent slipping are made of checkered steel plate. Checkered steel plate has uniformly sized protrusions (embossments) across the entire surface. However, if the surface of the checkered steel pallet is wet, the anti-slip effect may not be achieved depending on the condition of the tires mounted on the vehicle.

[0005] One object of the present disclosure is to provide a pallet that can provide an anti-slip effect for various vehicles that use parking lots. [Means for solving the problem]

[0006] A first aspect of the present disclosure relates to a parking lot pallet provided in a parking lot. The parking lot pallet has circular embossments at a pitch of 20 mm to 100 mm on at least the surface that comes into contact with vehicle tires.

[0007] A second aspect of the present disclosure relates to a mechanical parking system that parks vehicles on upper and lower levels. The mechanical parking system includes a lifting pallet that moves up and down between the upper and lower levels. The lifting pallet has circular embossments at a pitch of 20 mm to 100 mm on at least the surface that comes into contact with the vehicle tires. [Effects of the Invention]

[0008] According to the present disclosure, parking lot pallets have circular embossments at a pitch of 20 mm to 100 mm, at least on the surface that comes into contact with vehicle tires. This increases the frictional force acting on the contact surface between the vehicle tires and the pallet surface, making it less likely for the vehicle to slip. This makes it possible to realize a pallet that provides a slip-resistant effect for various vehicles that use the parking lot. [Brief explanation of the drawings]

[0010] A parking pallet and a mechanical parking system according to an embodiment of the present disclosure will be described with reference to the accompanying drawings. Elements common to the various drawings will be assigned the same reference numerals and redundant explanations will be omitted.

[0011] 1. First Embodiment 1-1. Parking lot example 1 and 2 are explanatory diagrams showing an example configuration of a parking lot 1 according to the first embodiment. The parking lot 1 is, for example, a mechanical parking lot. The mechanical parking lot is, for example, a two-tier mechanical parking lot capable of parking a vehicle 2 on each of two upper and lower tiers (upper tier and lower tier) as shown in FIG. 1. The two-tier mechanical parking lot may be configured as an above-ground two-tier mechanical parking lot installed on the ground, or as a two-tier pit mechanical parking lot in which the lower tier of the upper and lower tiers can be stored underground. The mechanical parking lot may also be a three-tier mechanical parking lot. In this case, the three-tier mechanical parking lot is configured as a three-tier pit mechanical parking lot in which the lower two tiers of the upper and lower three tiers can be stored underground. In this way, when the parking lot 1 is a pit mechanical parking lot, the parking lot 1 may be configured as a multi-tier mechanical parking lot.

[0012] As another example, parking lot 1 may be a surface parking lot rather than a mechanical parking lot.

[0013] As shown in FIG. 2, the parking lot 1 includes a pallet 10. The pallet 10 is a steel plate on which the vehicle 2 is placed and stored. For example, if the parking lot 1 is a two-level above-ground mechanical parking lot, the pallet 10 is provided on the upper level of the two levels. As another example, if the parking lot 1 is a pit-type mechanical parking lot, the pallets 10 are provided on all levels. The pallets 10 provided in the mechanical parking lot are also referred to as lifting pallets 10. As shown in FIG. 2(A), the lifting pallet 10 is attached to a support 5, and moves up and down based on the operation of a drive unit (not shown). For example, if the parking lot 1 is a two-level above-ground mechanical parking lot, the lifting pallet 10 moves up and down between the upper and lower levels in accordance with the operation of the drive unit.

[0014] When the parking lot 1 is a flat parking lot, the pallet 10 is fixedly installed on the ground as shown in Fig. 2(B) An example of the configuration of the pallet 10 will be described in detail later.

[0015] 1-2. Palette configuration example 1-2-1. Overview Consider a case where parking lot 1 is installed outdoors. For example, if the surface of pallet 10 is wet due to rain or the like, vehicle 2 moving on pallet 10 will be more likely to slip than if the surface of pallet 10 is dry. Specifically, if the surface of pallet 10 is dry, the frictional force acting on the contact surface between the tires of vehicle 2 and the surface of pallet 10 will be greater, and if the surface of pallet 10 is wet, the frictional force acting on the contact surface between the tires of vehicle 2 and the surface of pallet 10 will be smaller. If the frictional force acting on the contact surface between the tires of vehicle 2 and the surface of pallet 10 is greater, vehicle 2 will be less likely to slip. If the frictional force acting on the contact surface between the tires of vehicle 2 and the surface of pallet 10 is smaller, vehicle 2 will be more likely to slip.

[0016] Furthermore, there are various types of vehicles 2 that use the parking lot 1, and the performance of the tires fitted to the vehicles 2 also varies. For example, grip is an indicator of tire performance. Generally, if a tire with high grip is fitted to the vehicle 2, the vehicle 2 will not slip easily even if the surface of the pallet 10 is wet. However, if the tire is in a deteriorated state, the grip decreases and the vehicle 2 will be more likely to slip.

[0017] In this way, it is desirable to provide the parking lot 1 with a pallet 10 that can provide an anti-slip effect for various vehicles 2 that use the parking lot 1. The pallet 10 according to this embodiment will be described in detail below.

[0018] 1-2-2.Specific examples Figure 3 is an explanatory diagram showing an example configuration of pallet 10 according to embodiment 1. When viewed from above, circular embossments are provided on the surface of pallet 10. Pallet 10 may be configured so that the circular embossments are provided on the entire surface of pallet 10, or as shown in Figure 3, the circular embossments may be configured to consist of two groups (a first group FS and a second group SS).

[0019] For example, it is not necessary to provide circular embossments on the surface of the pallet 10 that does not come into contact with the tires of the vehicle 2. In this case, the pallet 10 may be configured with two sets of circular embossments (first set FS, second set SS). In other words, no circular embossments are provided between the first set FS and the second set SS. This shortens the time required to process the embossments, and reduces the cost of the pallet 10.

[0020] The circular embossments preferably have a diameter ranging from 8 mm to 20 mm and a height ranging from 2 mm to 5 mm. In a particularly preferred example, the circular embossments have a diameter of 11 mm and a height of 3.3 mm. The spacing (pitch) between the circular embossments is preferably from 20 mm to 100 mm. In a particularly preferred example, the spacing between the circular embossments is 20 mm. However, the diameter, height, pitch, and number of the circular embossments may be determined arbitrarily during the design and manufacturing of the pallet 10. For example, if circular embossments are provided at a narrow pitch on the surface of the pallet 10 that comes into contact with the tires of the vehicle 2, the pitch of the circular embossments may be narrower in locations where the vehicle 2 is slippery.

[0021] In this way, circular embossments are provided at a narrow pitch of 20 mm to 100 mm on at least the surface of the pallet 10 where the tires of the vehicle 2 come into contact. By freely arranging the circular embossments on the pallet 10 taking into account slippery areas of the vehicle 2, the frictional force acting on the contact surface between the tires of the vehicle 2 and the surface of the pallet 10 increases, making it less likely for the vehicle 2 to slip. Therefore, a pallet 10 can be realized that provides an anti-slip effect for various vehicles 2 that use the parking lot 1.

[0022] FIG. 4 is an explanatory diagram showing an example of evaluation results of the anti-slip effect of the pallet 10 according to the first embodiment. Specifically, FIG. 4(A) shows an example of calculation results of the friction coefficient of the test pallet using a test tire. The test pallet includes a pallet 10 with circular embossments and a checkered steel pallet. The road surface conditions include a "dry state" and a "wet state." The test tire is set to, for example, a load of 4030 [N]. The example shown in FIG. 4(A) shows the calculation results of the friction coefficient of the test pallet (pallet 10, checkered steel pallet) for each of the "dry state" and "wet" road surface conditions. In addition, the example shown in FIG. 4(A) shows the calculation results of the friction coefficient of the test pallet for each of three test runs. FIGS. 4(B) and 4(C) show example measurement results of the longitudinal force and load of the test tire. Specifically, Fig. 4(B) shows an example of measurement results of the longitudinal force and load of the verification tire when the verification pallet is "pallet 10," the road surface condition is "wet," and the number of verification runs is "1." Fig. 4(C) shows an example of measurement results of the longitudinal force and load of the verification tire when the verification pallet is "checkered steel pallet," the road surface condition is "wet," and the number of verification runs is "1."

[0023] The friction coefficient of the test pallet is calculated by dividing the longitudinal force of the test tire by the load of the test tire. The friction coefficient of the test pallet shown in Figure 4(A) is the average value of the friction coefficient in a specified section where the test tire is sliding (the section from 35 mm to 55 mm). According to Figure 4(A), the friction coefficient of the pallet 10 is greater than that of the checkered steel pallet, regardless of whether the road surface is "dry" or "wet." Therefore, the pallet 10 of the present disclosure can achieve a better anti-slip effect than the checkered steel pallet.

[0024] Consider the shape of the pallet 10. If the parking lot 1 is a flat parking lot, the pallet 10 has a flat shape. On the other hand, if the parking lot 1 is a mechanical parking lot, the pallet 10 (lifting pallet 10) may have a shape with an inclined entrance / exit. In this case, as shown in FIG. 3, the lifting pallet 10 has an inclined entrance / exit section 10A and a loading top section 10B. Also, as shown in FIG. 3, the lifting pallet 10 is provided with a first stopper 6 for preventing a vehicle 2 stopped during lifting / lowering from moving forward, and a second stopper 14 for preventing a vehicle 2 from entering while the vehicle 2 is moving.

[0025] The boarding / alighting ramp 10A is configured in a shape that allows the vehicle 2 to get on and off the loading top plate 10B, and the loading top plate 10B is configured in a flat shape that allows the vehicle 2 to be placed on it. In this case, when the tires of the vehicle 2 are positioned on the boarding / alighting ramp 10A, the tires are more likely to slip than when they are positioned on the loading top plate 10B. For this reason, the density of the embossing is higher on the boarding / alighting ramp 10A than on the loading top plate 10B. This provides an anti-slip effect when the vehicle 2 gets on and off the pallet 10 (boarding / alighting ramp 10A).

[0026] The distance between the first set FS and the second set SS of circular embossments is narrower on the boarding / exiting sloped section 10A than on the loading top plate section 10B, so that the tires of the vehicle 2 always come into contact with the circular embossments no matter which direction the vehicle 2 approaches.

[0027] 2. Second Embodiment 5 is an explanatory diagram showing a configuration example of the parking lot 1 according to embodiment 2. When the parking lot 1 is a two-level above-ground mechanical parking lot, the parking lot 1 may further include a boarding / exiting plate 11 and a stopper plate 12.

[0028] The boarding / alighting plate 11 is provided at the entrance / exit of the lower level of the upper and lower two levels. The boarding / alighting plate 11 is configured in a shape that allows passengers to get on and off the lower level of the vehicle 2. The boarding / alighting plate 11 is attached to the top of a base plate 13, which is fixedly installed on the ground, using fastening parts 20 (e.g., bolts).

[0029] The stopper plate 12 is provided at the back of the lower stage of the two stages, upper and lower. A third stopper 15 for preventing the entry of the vehicle 2 is provided on the stopper plate 12. The stopper plate 12 is attached to the top of a base plate 13, which is fixed to the ground, using fastening parts 30 (e.g., bolts). The third stopper 15 is also attached to the top of the stopper plate 12 using the fastening parts 30.

[0030] The boarding / exiting plate 11 and the stopper plate 12 are provided with circular embossments at least on the surfaces that come into contact with the tires of the vehicle 2. This allows the boarding / exiting plate 11 and the stopper plate 12 to have an anti-slip effect when the vehicle 2 gets on and off, even if the parking lot 1 is a two-level above-ground mechanical parking lot and the vehicle 2 is parked on the lower level.

[0031] Furthermore, the boarding / alighting plate 11 and the stopper plate 12 may have a shape in which the boarding / alighting entrance portion is inclined and the other portions are flat, as shown in Fig. 5. In this case, the density of the embossing is higher in the boarding / alighting entrance portion than in the other portions. This provides a better anti-slip effect when the boarding / alighting plate 11 and the stopper plate 12 are used by the vehicle 2 to get on and off. [Explanation of symbols]
