Description

[Technical field]

[0001] The present invention relates to a mechanical parking device, and more particularly to a parking device equipped with a mechanism for raising and lowering a pallet using a wire, chain, or the like. [Background technology]

[0002] 2. Description of the Related Art Mechanical parking systems are known as systems that make effective use of limited land areas and allow parking of a greater number of vehicles. A mechanical parking system is a system for parking cars in a multi-level manner. A typical mechanical parking system has a pallet on which the car is placed and a lifting device for raising and lowering the pallet. In a mechanical parking system, a vehicle is introduced into a pallet storage area from the vehicle entrance and exit, the vehicle is placed on the pallet, and the pallet is raised and lowered to place the vehicle on a specified floor. Moreover, what is called a puzzle-type multi-story parking device has a function of not only raising and lowering a pallet but also moving the pallet sideways. A multi-story parking device is disclosed in, for example, Patent Document 1. In the parking device disclosed in Patent Document 1, a pallet is suspended by a chain. The parking device disclosed in Patent Document 1 is provided with a fall prevention device that prevents the pallet from falling. The fall prevention device has a stopper that appears and disappears on the ascending and descending path of the pallet. Even if the chain suspending the pallet breaks and the pallet loses its support and falls, the pallet will hit a stopper and stop falling, preventing it from falling all the way to the bottom. Therefore, even if the chain breaks, it will not lead to a serious accident. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2021-161748 A Summary of the Invention [Problem to be solved by the invention]

[0004] The stopper is biased by a spring in a direction that causes it to protrude onto the lifting path. When the stopper is pressed in a retracting direction from the lifting path side, it retracts from the lifting path against the spring. Therefore, if part of the pallet hits the stopper when the pallet is rising, the stopper is pushed by the pallet and retracts. Therefore, even if part of the pallet hits the stopper when the pallet is rising, the pallet will rise without any problems. However, if a part of the pallet gets caught on the housing of the fall prevention device when the pallet is raised, the pallet cannot be raised. Furthermore, if the pallet gets caught on a member other than the fall prevention device, the pallet cannot be raised.

[0005] The present invention is intended to solve the above-mentioned problems, and provides a parking device that is less likely to get caught on other objects when the pallet (mounting platform) is raised. [Means for solving the problem]

[0006] An aspect for solving the above-mentioned problems is a parking device having a platform and a lifting mechanism for raising and lowering the platform and stopping it at a lowered position and an elevated position, and for loading a vehicle onto the platform and parking the vehicle in a multi-level manner, the parking device having a guide member for guiding at least a portion of the platform, the guide member having a pair of engaging and engaged portions, one of the engaging and engaged portions being located near a elevated position and the other of the engaging and engaged portions being installed on the platform, and when the platform rises and approaches the elevated position, the engaging portion engages with the engaged portion, and at least a portion of the platform is guided by the guide member to rise along a predetermined elevated trajectory.

[0007] Many members that may become an obstacle when the mounting table is raised are located near the raised position of the mounting table. This embodiment focuses on this point, and one of the engaging portion and the engaged portion of the guide member is located near the raised position, and the other is installed on the mounting table. When the mounting table rises and approaches the raised position, the engaging portion engages with the engaged portion, and the mounting table is guided by the guide member to rise along a predetermined upward trajectory. Therefore, when the mounting table is near the raised position, it rises along the predetermined upward trajectory and does not get caught on other members.

[0008] In the above aspect, it is preferable that the engaging portion has a rod-shaped portion, the engaged portion has a hole, and the rod-shaped portion is inserted into the hole to regulate the movement trajectory of at least a part of the mounting table.

[0009] In this embodiment, when the mounting table rises and approaches the raised position, the rod-shaped portion of the engaging portion enters the hole of the engaged portion to guide the mounting table.

[0010] In each of the above-mentioned aspects, the engaging portion has a rod-shaped portion, the engaged portion has a hole, and the rod-shaped portion is inserted into the hole to regulate at least a portion of the movement trajectory of the mounting table, and it is desirable that the cross-sectional area of ​​the opening of the hole is significantly larger than the cross-sectional area of ​​the rod-shaped portion, and that the rear side of the hole has a cross-sectional area smaller than that of the opening.

[0011] In this embodiment as well, when the mounting table rises and approaches the raised position, the rod-shaped portion of the engaging portion enters the hole of the engaged portion to guide the mounting table. In this embodiment, the cross-sectional area of ​​the opening of the hole in the engaged part is considerably larger than the cross-sectional area of ​​the rod-shaped part. Therefore, when the mounting table rises and the rod-shaped part of the engaging part approaches the hole in the engaged part and reaches the position of the hole, the rod-shaped part enters the hole in the engaged part even if the axis of the rod-shaped part is offset from the center of the hole. Then, when the mounting table rises further, the rod-shaped part reaches the back side of the hole. In this embodiment, the cross-sectional area of ​​the back side of the hole is smaller than the opening of the hole, so the movement trajectory of the mounting table is restricted and the amplitude of the vibration is reduced, and the mounting table rises linearly.

[0012] In each of the above-mentioned aspects, it is desirable that the engaging portion has a rod-shaped portion, the engaged portion has a hole, the rod-shaped portion is inserted into the hole to regulate at least a portion of the movement trajectory of the mounting table, the hole has a funnel-shaped portion near an opening and a straight portion at the back side of the hole, and the rod-shaped portion is guided by the funnel-shaped portion and enters the straight portion.

[0013] In this embodiment as well, when the mounting table rises and approaches the raised position, the rod-shaped portion of the engaging portion enters the hole of the engaged portion to guide the mounting table. In this embodiment, the hole of the engaged part has a funnel-shaped part near the opening. Also, there is a straight part at the back of the hole. Therefore, when the mounting table rises and the rod-shaped part of the engaging part approaches the hole of the engaged part and reaches the position of the hole, even if the axis of the rod-shaped part is offset from the center of the hole, the rod-shaped part enters the funnel-shaped hole of the engaged part. Then, when the mounting table rises further, the rod-shaped part is guided toward the center along the inclined surface of the funnel-shaped part of the opening and enters the straight part at the back of the hole. Thereafter, the rod-shaped part is guided to the straight part, the movement trajectory of the mounting table is regulated, the amplitude of the vibration is reduced, and the mounting table rises linearly.

[0014] In each of the above-mentioned aspects, the engaging portion has a rod-shaped portion, the engaged portion has a hole, the rod-shaped portion is inserted into the hole to regulate the movement trajectory of at least a portion of the mounting table, and it is desirable that the tip of the rod-shaped portion is thinner than the base side.

[0015] In this embodiment as well, when the mounting table rises and approaches the raised position, the rod-shaped portion of the engaging portion enters the hole of the engaged portion to guide the mounting table. In this embodiment, the tip of the rod-shaped portion is thinner than the base thereof, so that when the mounting table is raised and the rod-shaped portion of the engaging portion approaches the hole of the engaged portion and reaches the position of the hole, the rod-shaped portion will enter the hole of the engaged portion even if the axis of the rod-shaped portion is offset from the center of the hole.

[0016] In each of the above aspects, it is preferable that the engaging portion is fixed at a raised position, and the engaged portion is placed on the placement table.

[0017] In each of the above-mentioned aspects, the vehicle has a foundation frame that constitutes the floor on which the vehicle is placed, and a lateral frame that is installed on a specified floor of the foundation frame and laterally travels on that floor, and the platform is suspended from the lateral frame by a cable member and raised and lowered, and it is desirable that one of the engaging portion and the engaged portion is provided on the lateral frame.

[0018] According to this aspect, the platform can be moved laterally, so that more vehicles can be accommodated.

[0019] In each of the above-mentioned aspects, it is preferable that a fall prevention device is provided to prevent the mounting table from falling, and the guide member guides a part of the mounting table when the mounting table passes the position of the fall prevention device.

[0020] In this embodiment, since the fall prevention device is provided, even if the cable member such as the wire breaks, the mounting table will not fall. Furthermore, when the mounting table is raised, the mounting table does not interfere with the fall prevention device, and the mounting table can be raised smoothly. Effect of the Invention

[0021] The parking device of the present invention is less likely to get caught on other objects when the platform is raised, and is less likely to malfunction. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] An embodiment of the present invention will be described below. First, an overview of the parking device 1 will be described. In the following description, the "front side" and the like refer to the front side of the parking device 1, which is the side from which the vehicle 100 enters and exits. The "rear side" and the like refer to the rear side of the parking device 1, which is the opposite side to the "front side." The "side" and "width direction" refer to the left-right direction in FIG. 1. The parking device 1 of this embodiment is a mechanical parking device. The parking device 1 is a puzzle-type multi-story parking device, and has a function of raising and lowering a pallet (mounting platform) 10 and a function of moving it sideways. The parking device 1 of this embodiment has a base frame 2, on which a plurality of parking units 3 are installed.

[0024] The foundation frame 2 is framed by steel materials and constitutes the outer shell of the parking device 1. As shown in Figures 1 to 4, the foundation frame 2 has a five-story structure and is divided into the ground floor A, the second floor B, the third floor C, the fourth floor D, and the fifth floor E. As shown in Figs. 1 and 3, the base frame 2 has a first space a, a second space b, and a third space c in the width direction. On each floor, lateral rails 11a, 11b are installed as shown in Figures 2 and 4. Both of the lateral rails 11a, 11b are steel members installed in the width direction of the foundation frame 2. The lateral rail 11a is installed on the front side of each floor, and the lateral rail 11b is installed on the rear side of each floor.

[0025] The parking unit 3 is composed of a pair of a traverse frame 5 and a pallet 10, as shown in Figs. The traverse frame 5 has a frame body 12, a hoisting device 13, a traverse mechanism 15, a pulley 16, and a fall prevention device 17. Two pulleys 16 are attached to the frame body 12, and four fall prevention devices 17 are attached to the frame body 12. The frame body 12 is a generally rectangular frame made of steel. That is, the frame body 12 is configured with a front horizontal member 41 and a rear horizontal member 42 arranged in parallel with each other and a vertical member 43 connected between them to form a rectangle.

[0026] The winding device 13 is composed of two winding drums 20a, 20b and a drive mechanism 21 that rotates the winding drums 20a, 20b. The winding drums 20a and 20b are for winding wires (cord members) 22a, 22b, 23a, and 23b. The winding drums 20a and 20b are provided with drum side grooves 25 into which the wires 22a, 22b, 23a, and 23b fit. The drive mechanism 21 is made up of a geared motor 26, a connecting member 18 that connects the two winding drums 20a, 20b, and a power transmission mechanism .

[0027] In this embodiment, two winding drums 20a, 20b are connected by a connecting member 18. That is, the winding drums 20a, 20b are attached to both ends of the connecting member 18. A sprocket 27 is provided in the middle of the connecting member 18. A sprocket 30 is attached to the geared motor 26. A chain 31 is wound around the sprocket 30 on the geared motor 26 and a sprocket 27 of the connecting member 18. That is, in this embodiment, the two sprockets 27, 30 and the chain 31 constitute a power transmission mechanism 28.

[0028] The traverse mechanism 15 is made up of four rollers 38 and a drive device (not shown).

[0029] The fall prevention device 17 is a known device, and a stopper member 33 protrudes from and retracts into a box body 32. The box body 32 of the fall prevention device 17 is a vertically long rectangular parallelepiped as shown in Fig. 11. The box body 32 is formed with a slit 37 through which the stopper member 33 protrudes. The box 32 houses a solenoid and a spring (not shown). The stopper member 33 is substantially triangular, and has a substantially horizontal receiving surface 48 and an inclined surface 36 as shown in FIG. The stopper member 33 is constantly protruding from the box body 32 by a spring (not shown). The position of the stopper member 33 is as shown in Fig. 11, in which the substantially horizontal receiving surface 48 faces upward, and the amount of protrusion of the inclined surface 36 increases from the bottom to the top. As described above, a solenoid is built into the box body 32, and the stopper member 33 is recessed into the box body 32 by driving the solenoid.

[0030] Next, the relationship between the members constituting the traverse frame 5 will be described. As described above, the traverse frame 5 has the frame body 12, the hoisting device 13, the traverse mechanism 15, two pulleys 16, and four fall prevention devices 17 provided thereon. The hoisting device 13 is attached to the rear cross member 42 of the frame body 12. The hoisting device 13 is installed on the rear cross member 42. The traverse mechanism 15 is provided on the rear cross member 42 and the front cross member 41 of the frame body 12. That is, two rollers 38 protrude rearward from the rear cross member 42. Also, two rollers 38 protrude forward from the front cross member 41.

[0031] The pulley 16 is disposed on the vertical member 43 of the frame body 12 in the vicinity of the front horizontal member 41 . Two of the four fall prevention devices 17 are vertical members 43 and are provided near the front horizontal member 41. The other two of the four fall prevention devices 17 are vertical members 43 and are provided near the rear horizontal member 42. The four fall prevention devices 17 each have their upper end supported by a vertical member 43 , and most of the box body 32 hangs down from the vertical member 43 . The fall prevention devices 17 are all installed with the stopper members 33 facing inward of the traverse frame 5. The fall prevention device 17 may be attached to any member or at any position. For example, the fall prevention device 17 may be attached to the front horizontal member 41 or the rear horizontal member 42 of the frame main body 12, the pillars or beams of the foundation frame 2, the lateral rails 11a and 11b, or the like. Furthermore, there are no limitations on the shape or structure of the fall prevention device 17, as long as some kind of obstacle appears under the pallet 10 to prevent the pallet 10 from falling.

[0032] Next, the pallet 10 will be described. The pallet 10 is a platform on which the vehicle 100 is placed. The cross-sectional shape of the main body of the pallet 10 is "concave", and there is a vehicle placement area 45 in which the vehicle 100 is placed in the center in the width direction. The vehicle placement area 45 is a flat area occupied by the vehicle 100. In this embodiment, the wheels of the vehicle 100 come into contact with the ground in the vehicle placement area 45. In this embodiment, the portion of the vehicle placement area 45 where the wheels of the vehicle are placed is the wheel placement area. There are raised portions 46 on both sides of the vehicle placement area (vehicle mounting portion) 45. The upper surface of the raised portions 46 is flat. In the actual pallet 10, there are protrusions and cutouts on the sides and front and rear end faces of the main body for attaching accessories, but the vehicle placement area 45 is a rectangular area that is part or all of the main body of the pallet 10. The front end of the vehicle placement area 45 is the front end of the main body of the pallet 10, and the rear end of the vehicle placement area 45 is the rear end of the main body of the pallet 10. A guide roller 47 is provided on the side surface of the pallet 10 near the rear end. The guide roller 47 rotates freely.

[0033] The parking unit 3 is composed of a traverse frame 5 and a pallet 10, and the pallet 10 is suspended from the traverse frame 5 so as to be able to rise and fall. In this embodiment, the pallet 10 is suspended by four wires 22a, 22b, 23a, and 23b. In this embodiment, the lifting mechanism is made up of members that suspend the four wires 22a, 22b, 23a, and 23b and members that pay out and wind in the four wires 22a, 22b, 23a, and 23b. That is, in this embodiment, the lifting mechanism is made up of the wires 22a, 22b, 23a, and 23b, the winding drums 20a and 20b that wind the wires, the geared motor 26 that drives the winding drums 20a and 20b, the connecting member 18, the power transmission mechanism 28, and the pulley 16 that suspends the wires. The structure for rotating the winding drums 20a and 20b is not limited, and each of the winding drums 20a and 20b may be provided with a separate motor for rotating the winding drums 20a and 20b. In addition, the winding drums 20a and 20b may be directly connected to a geared motor, or the winding drums 20a and 20b may be connected to a geared motor. The motor may be built in. The wires 22a and 22b are front-hanging wires, and one end of each wire is connected to the front side of the pallet 10. The wires 23a and 23b are rear-hanging wires, and one end of each wire is connected to the rear side of the pallet 10.

[0034] In this embodiment, one front hanging wire 22a and one rear hanging wire 23a are wound around one winding drum 20a, and one front hanging wire 22b and one rear hanging wire 23b are wound around the other winding drum 20b. The base ends of the front hanging wires 22a, 22b are wound around the winding drums 20a, 20b, and the tip ends are connected to the front side of the pallet 10 via the pulley 16. That is, the winding path of the front hanging wires 22a, 22b is as shown in Figures 9 and 10(a), and is connected from the winding drums 20a, 20b to the front side of the pallet 10 via the pulley 16. The suspension position of the front hanging wires 22a, 22b between the winding drums 20a, 20b and the pulley 16 is inclined slightly downward from the winding drums 20a, 20b toward the pulley 16. The suspension position of the front hanging wires 22a, 22b between the pulley 16 and the pallet 10 is vertically downward.

[0035] The winding paths of the rear hanging wires 23a, 23b are as shown in Figs. 9 and 10(b), and are connected directly to the rear side of the pallet 10 from the winding drums 20a, 20b. The rear suspension wires 23a, 23b between the winding drums 20a, 20b and the pallet 10 are directed vertically downward.

[0036] Next, the relationship between the base frame 2 and the parking unit 3 will be described. In the parking device 1 of this embodiment, as shown in Fig. 1, two parking units 3 are installed from the second floor B portion to the fourth floor D portion of the base frame 2, and three parking units 3 are installed on the fifth floor E portion of the base frame 2. In this way, on the top floor, the number of spaces and the number of parking units 3 are the same, and on the intermediate floors, the number of parking units 3 is less than the number of spaces. The parking unit 3 is placed on the lateral rails 11a, 11b of the base frame 2. That is, the rollers 38 of the lateral mechanism 15 protruding in the front-rear direction from the frame body 12 of the lateral frame 5 are placed on the lateral rails 11a, 11b installed at the front and rear of the base frame 2. Therefore, by driving the rollers 38 of the traverse mechanism 15, the parking unit 3 moves laterally.

[0037] Next, the basic functions of the parking device 1 will be described. The parking device 1 of this embodiment is a puzzle-type multi-story parking device, and on the top floor, the fifth floor E, parking units 3 are installed in all of the first space a, second space b, and third space c. In contrast, there are no parking units 3 on the ground floor A, which is the loading and unloading floor. On the intermediate floors, the second floor B, third floor C, and fourth floor D, parking units 3 are installed in a number that is one less than the number of spaces.

[0038] When parking the vehicle 100 on the ground floor A, a gate (not shown) is opened and the vehicle 100 is placed into any one of the first space a, the second space b, or the third space c on the ground floor A. When parking the vehicle 100 in a parking unit 3 installed on an upper floor, the pallet 10 of the parking unit 3 is lowered to the ground floor (lowered position) A. For example, when parking the vehicle 100 in the parking unit 3 located in the third space c at the right end of the fourth floor D, the parking units 3 on the lower floors, the third floor C and the second floor B, are moved sideways to open the bottom of the third space c at the right end of the fourth floor D where the vehicle 100 is to be lowered. Alternatively, when the vehicle 100 located in the second space b in the center of the fourth floor D is to be lowered, the parking units 3 are moved sideways to move the parking unit 3 to a position where the space below is vacant.

[0039] Then, the driving mechanism 21 is driven to rotate the winding drums 20a and 20b, and the four wires 22a, 22b, 23a, and 23b are paid out from the winding drums 20a and 20b. As a result, the pallet 10 of the parking unit 3 is lowered to the ground floor A, which is the lowering position. Then, the vehicle 100 is placed on the pallet 10, the drive mechanism 21 is driven to rotate the winding drums 20a, 20b in the reverse direction, and the four wires 22a, 22b, 23a, 23b are wound around the winding drums 20a, 20b, and the four wires 22a, 22b, 23a, 23b are pulled up. As a result, the pallet 10 of the parking unit 3 rises and stops at a predetermined raised position. The raised position of the pallet 10 is near the traverse frame 5 and is slightly lower than the traverse frame 5.

[0040] Next, a characteristic configuration of the parking device 1 of this embodiment will be described. In the parking device 1 of this embodiment, the pallet 10 passes beside the fall prevention device 17 when the pallet 10 is raised or lowered. When the pallet 10 is lowered, a solenoid (not shown) of the fall prevention device 17 is driven by a signal from a control device (not shown) to house the stopper member 33 in the box body 32 . On the other hand, when the pallet 10 is raised from the ground floor A as the lowered position to the vicinity of the traverse frame 5 as the raised position, the solenoid is not driven and the stopper member 33 is in a protruding state. When the pallet 10 is raised from this state, a part of the pallet 10 comes into contact with the lower side of the stopper member 33. Here, the lower side of the stopper member 33 is an inclined surface 36, so when the pallet 10 is raised while in contact with the lower inclined surface 36 of the stopper member 33, a horizontal component force is generated in the stopper member 33, and the stopper member 33 is pushed into the box body 32. Therefore, when the pallet 10 is raised while in contact with the lower inclined surface 36 of the stopper member 33, the pallet 10 reaches the vicinity of the traverse frame 5, which is the raised position, without any problems.

[0041] However, when the pallet 10 is raised, if the pallet 10 sways and its ascending trajectory deviates from the intended trajectory, the pallet 10 will collide with the box 32 of the fall prevention device 17 . Furthermore, if the pallet 10 swings, it may collide with something other than the fall prevention device 17. For example, the pallet 10 may hit accessories such as a positioning sensor, a limit switch, a light, etc. The pallet 10 may also hit the lateral rails 11a, 11, etc. of the base frame 2.

[0042] In the parking device 1 of this embodiment, a guide member 50 is provided on the parking unit 3 to prevent the pallet 10 from colliding with the box body 32 of the fall prevention device 17, a sensor, etc. when the pallet 10 is raised. The guide member 50 is composed of a pin member (engaging portion) 51 and a receiving member (engaged portion) 52 in the shape of a mortar. The pin member (engagement portion) 51 is a rod-shaped member made of metal or resin and has a pointed tip. That is, the pin member (engagement portion) 51 is a rod-shaped member having a circular cross-sectional shape, and the tip side 53 is pointed and thinner than the base side 55. In this embodiment, the pin member (engagement portion) 51 is made of steel. The overall length of the pin member (engagement portion) 51 is about 30 cm to 80 cm. The thickness of the base portion is about 10 mm to 20 mm, and it can withstand a considerable bending stress.

[0043] The receiving member (engaged portion) 52 is made of metal or resin, and has a cylindrical appearance. A through hole 60 is formed in the center of the receiving member (engaged portion) 52. A funnel-shaped portion 61 is provided at the opening of the through hole 60, and a linear portion 62 is provided on the inner side (lower side). That is, the opening diameter of the opening end of the through hole 60 is considerably larger than the base portion of the pin member 51. In this embodiment, the opening diameter of the opening end of the through hole 60 is approximately two to five times larger than the base portion of the pin member 51. The inner diameter of the straight portion 62 is slightly larger than the base portion of the pin member 51. Specifically, the inner diameter of the straight portion 62 is large enough that the base portion of the pin member 51 can pass through with ease, and the inner diameter of the straight portion 62 is larger than the base portion of the pin member 51 by about 0.5 mm to 2 mm. The funnel-shaped portion 61 is approximately half the height of the receiving member 52 , and the remaining half is a straight portion 62 . The opening angle of the funnel-shaped portion 61 is approximately 45 degrees to 120 degrees.

[0044] The overall height of receiving member (engaged portion) 52 is considerably smaller than the overall length of pin member 51, and the overall height of receiving member 52 is half or less of pin member 51, so that pin member 51 can pass through receiving member 52.

[0045] In this embodiment, two sets of guiding members 50 are installed on the left and right sides of the front area of ​​the parking unit 3, and there is none on the rear side. In this embodiment, the pin members 51 are attached to the traverse frame 5 side, and the receiving members 52 are attached to the pallet 10. Specifically, the pin member 51 is attached to the vertical member 43 of the traverse frame 5 in the vicinity of the front fall prevention device 17. The pin member 51 is attached in a cantilevered manner from the vertical member 43 of the traverse frame 5, with the tip side of the pin member 51 facing downward. The height of the tip of the pin member 51 is lower than the lowest part of the fall prevention device 17. The receiving member 52 is located directly below the pin member 51 , and the axis of the pin member 51 coincides with the axis of the receiving member 52 .

[0046] 5, in the base frame 2, vertical guides 63 are provided in the rear areas of the first space a, the second space b, and the third space c, and the guide rollers 47 are engaged with the vertical guides 63. Therefore, when the pallet 10 is lifted, the guide rollers 47 engage with the vertical guides 63 to regulate the lateral shaking of the rear side of the pallet 10. On the other hand, the lateral swing of the front side of the pallet 10 is restricted by the guide member 50.

[0047] The function of the guide member 50 will now be described. In the parking device 1 of this embodiment, when the pallet 10 is raised from the ground floor A as a descending position to the vicinity of the traverse frame 5 as an ascending position and the height of the pallet 10 approaches the box body 32 of the fall prevention device 17, the pin member (engaging portion) 51 enters the through hole 60 of the receiving member (engaged portion) 52, and the pin member 51 engages with the linear portion 62 of the receiving member 52. As a result, the front side of the pallet 10 rises linearly along the linear portion 62 of the receiving member 52 and passes beside the fall prevention device 17 without swaying sideways. In other words, the movement trajectory of a part of the pallet 10, particularly the part that passes beside the fall prevention device 17 when rising, is restricted to be linear, eliminating swaying sideways.

[0048] That is, since the height of the tip of the pin member 51 is lower than the lowest part of the fall prevention device 17, the pin member 51 fixed to the traverse frame 5 engages with the through hole 60 of the receiving member 52 fixed to the pallet 10 before the pallet 10 rises and reaches the height of the lowest part of the fall prevention device 17. Therefore, when the pallet 10 rises further and reaches the height of the lowest part of the fall prevention device 17, the sway of the upward trajectory of the pallet 10 is reduced by the guide member 50, and the movement trajectory of the pallet 10 is corrected to a straight trajectory. Therefore, in the parking device 1 of this embodiment, the pallet 10 does not collide with the box body 32 of the fall prevention device 17 when the pallet 10 rises.

[0049] Furthermore, the receiving member 52 employed in this embodiment has a funnel-shaped portion 61 at the introduction portion of the pin member 51, and the cross-sectional area of ​​the opening of the through-hole 60 of the receiving member 52 is considerably larger than the cross-sectional area of ​​the pin member 51. In addition, the pin member 51 is pointed and has an extremely small area. Therefore, as shown in Figure 14(a), when the pallet 10 rises and the pin member 51 reaches the position of the through hole 60 of the receiving member 52, even if the axis of the pin member 51 is offset from the center of the through hole 60, the pin member 51 enters the funnel-shaped portion 61 of the through hole 60 as shown in Figure 14(b). Then, when the pallet 10 rises further, the tip of the pin member 51 is guided by the slope of the funnel-shaped portion 61 and moves toward the center of the through hole 60 as shown in Figure 14(c). Finally, the pin member 51 enters the linear portion 62 of the through hole 60 as shown in Figure 14(d).

[0050] The pallet 10 continues to rise, but the upward trajectory of the pallet 10 after the pin members 51 enter the through holes 60 is restricted by the guide members 50 so that the pallet 10 moves in a straight line. Therefore, the pallet 10 does not sway sideways and does not collide with the box 32 of the fall prevention device 17 or other accessories.

[0051] In the embodiment described above, two sets of the guide members 50 are installed on the left and right sides of the front area of ​​the parking unit 3, and there is no guide member 50 on the rear side, but the guide members 50 may be provided on the rear side of the parking unit 3. That is, the guide members 50 may be provided in four places on the parking unit 3. Furthermore, more guide members 50 may be provided.

[0052] In the embodiment described above, the main purpose is to prevent the pallet 10 from colliding with the fall prevention device 17, but as described above, components such as sensors and switches are often installed near the raised position of the pallet 10. Therefore, a guide member 50 may be provided to avoid collision with these components.

[0053] Regardless of the objective of avoiding a collision with any component, it is desirable to complete the engagement between the pin member 51, which is the engaging portion, and the receiving member, which is the engaged portion, before the pallet 10 reaches the height of the component that will be hit, thereby restricting the movement trajectory of the pallet 10 to a linear one and preventing the pallet 10 from shaking.

[0054] In this embodiment, the pin members 51 serving as the engaging portion are provided on the upper traverse frame 5, and the receiving member (engaged portion) 52 is provided on the lower moving side, the pallet 10. The reason for this is that since people may ride on the pallet 10, if the pin members 51 are provided on the pallet 10 side, there is a concern that people may step on them and get injured. However, the present invention is not limited to this configuration, and the receiving member (engaged portion) 52 may be provided on the traverse frame 5, and the pin member 51 may be provided on the pallet 10 side. For example, the pin member 51 may be provided on the pallet 10 side with a length of 1 m that is unlikely to be stepped on. Also, safety may be ensured by providing the pin member 51 in a position where people cannot enter.

[0055] Either the engaging portion or the engaged portion may be provided on the base frame 2. For example, a pin member 51 may be provided on the lateral rails 11a, 11b.

[0056] In the embodiment described above, the guide member 50 is composed of a pin member (engagement portion) 51 constituting an engagement portion, and a receiving member 52 constituting an engaged portion. In this embodiment, the guide member 50 is made separately from members such as the traverse frame 5 and the pallet 10. However, the present invention is not limited to this configuration, and the engaging portion and the non-engaging portion may be a part of another member. For example, an opening may be provided in a part of the pallet 10, and the opening may function as an engaged portion to engage with the engaging portion.

[0057] The guide member 50 in this embodiment is primarily intended to prevent the pallet 10 from swaying sideways, but if, for example, the wires (rod members) 22a, 22b, 23a, 23b that hoist the pallet 10 are slightly uneven and the pallet 10 is rising in an inclined position, the guide member 50 can also be used to correct the position of the pallet 10 to a horizontal position.

[0058] The parking apparatus 1 described above has a structure with five above-ground floors and three spaces on each floor. That is, the parking apparatus 1 described above has a three-row, five-floor structure, but the number of floors and the number of rows are optional. For example, the present invention can be applied to a single-row, two-storey parking device. Furthermore, the present invention can be applied to a parking system having a basement.
