Description

  The present invention relates to a barrier-free elevator parking apparatus that can be used by a wheelchair user.

  As a conventional elevator-type parking device, a pallet turning device is provided on the pit floor of the entry section or the elevator itself so that the vehicle can be operated easily at the time of entering and leaving, and the pallet is placed at the time of entering and leaving. There is known a method (180 °, 90 °, or other angle turning) in which the front portion of the vehicle is directed to the entrance / exit by turning.

  As this type of prior art, for example, in an elevator parking device of 90 ° entry type, a pallet lifting and turning device is installed in the pit of the entry part (for example, see Patent Documents 1 and 2), or the elevator itself is lifted by a pallet Some have a turning device (see, for example, Patent Document 3).

  On the other hand, in recent years, the “New Barrier-Free Act” (Act on the Promotion of Facilitation of Movement of Elderly People, Persons with Disabilities, etc.) has been enacted, and it is an urgent task to make barrier-free even for multistory parking lots including the above-mentioned elevator type parking devices. ing. The main barrier-free elements in this elevator-type parking device are that the vehicle can be moved forward and forward when the vehicle enters and exits the pallet at the time of entry and exit, and the top surface of the pallet on which the vehicle is mounted. Make the whole flat (hereinafter referred to as “flat”), and when this flat pallet is placed at the entry level in the entry section, there is no step between the surrounding deck and the entry floor, making it easy for the wheelchair to travel There is something that can be done.

  By the way, in the barrier-free, in the case of the entry method in which the pallet is turned at a predetermined angle other than 180 ° between the warehousing direction and the leaving direction, there is a specific problem that does not occur in the case of the entry method in which the pallet is turned by 180 °. For example, as an entry system having a predetermined angle in the entry direction and the exit direction, a 90 ° entry type elevator parking device will be described as an example. As disclosed in Patent Documents 1 to 3, the pit floor and the elevator are used. The installed pallet lifting and swiveling device lifts the center of the pallet to a turning level above the elevator lifting frame, turns 90 °, then lowers to the entry level to land (the pallet road surface faces the entry floor) It is a method to make it one). Therefore, this pallet that has landed extends long in the front-rear direction in a direction orthogonal to the lifting frame.

  For this reason, a long pallet equipped with a vehicle is subjected to a vehicle load and both longitudinal end portions thereof are lowered to bend in an arc shape, and the front and rear end portions hang down in a free state suspended by an elevator. . The sagging caused by this deflection changes slightly each time due to the manufacturing error of the pallet itself, the weight of the mounted vehicle, and the unbalanced load due to the mounting position and posture of the vehicle on the pallet, so the pallet's road surface front end always faces the boarding floor. It is not possible to make it one, and there is a level difference between the surrounding decks.

As a means for preventing the pallet end from sagging, in Patent Document 1, the end of the pallet is placed on and supported by the entrance floor. Moreover, in patent document 2, the front part and rear part of a pallet are carried | supported by the raise of the raising / lowering stand installed in the front part and rear part of the entrance direction of a pit. Furthermore, in patent document 3, it mounts and supports on the pair of front-and-rear holding member horizontally mounted by the external channel | path part of the intermediate loading part.

  By the way, barrier-free in the above-mentioned 90-degree elevator-type elevator parking device is not a flat pallet with a flat upper surface for all the pallets accommodated, but a special pallet for barrier-free. It is thought that a part of will be replaced with a special pallet for wheelchair use. For this reason, when a normal standard pallet having a concave roadway on the left and right and a special pallet having a thickness equivalent to that of the standard pallet are mixedly mounted, a difference in height is inevitably caused between both pallets on the vehicle entry surface.

  Therefore, when a standard pallet having a height difference (height from the bottom surface of the pallet to the entry surface) and a special pallet are mixedly mounted on the vehicle entry surface, the end of the pallet is simply carried as in Patent Documents 1 to 3 above. Various problems arise when the means are used. That is, in Patent Documents 1 and 3, since the lower surface of the pallet is deposited on the fixed boarding floor and the holding member, there is a step on the loading surface of both pallets. Further, Patent Document 2 requires a special lifter having a complicated mechanical structure and an expensive structure, and requires additional control to change the lifting stroke so that both pallets can be individually loaded to match the level.

  Therefore, the present invention provides an elevator-type parking apparatus that is barrier-free so that it can be easily boarded and unloaded with a wheelchair even if the pallet is turned with a predetermined angle in the vehicle entry and exit directions. The purpose is to do.

  In order to achieve the above object, the present invention provides a pallet turning device for turning a pallet on which a vehicle is mounted, having a predetermined angle in the direction of entering and leaving the vehicle, and the pallet between the parking shelf and the pit.

Supported on one said at the time of implantation of the special pallet are provided pallet end bearing means for supporting the entrance floor and flush multiply said upper surface. “Flush” in the specification and claims includes a flat surface which is a substantially flat surface and does not have a step which hinders movement of the wheelchair. The “predetermined angle” refers to an angle other than 180 °. Thereby, in the elevator type parking apparatus that turns the pallet at an angle other than 180 ° at the time of loading and unloading, the road surface of the standard pallet that forms the concave roadway can be supported flush with the boarding floor, and the entire upper surface The road surface of a flat special pallet can be supported flush with the boarding floor, and the elevator deck can be formed flush with the fixed deck by raising and lowering the elevator. There is no level difference between the deck and elevator deck (entrance / exit deck) and the entrance floor, and it is made flat so that a wheelchair user can easily use the wheelchair to travel.

  Further, a support portion that supports the elevator deck flush with the fixed deck may be provided on the fixed deck. Accordingly, the elevator deck can be supported by the support portion of the fixed deck when the elevator is raised and lowered to form a flush deck.

  Furthermore, you may provide the inductor which irradiates visible light which shows the restriction | limiting range of a vehicle width direction in a vehicle entry direction in the said entry part. Thereby, it can be stored while confirming the position of the width direction easily at the time of boarding of a vehicle, and stable storage can be performed.

  Further, the special pallet may be a special pallet provided with a cover plate over the entire length of the concave lane of the standard pallet so that the entire top surface of the pallet is flat. Thus, the standard pallet can be used as a special pallet, and the standard pallet and the special pallet can be formed using a common pallet.

  In addition, the pallet end carrying means, a guide block for guiding both sides of the special pallet to a predetermined height position in the pit where the elevator is located, and a support material for supporting the lower part of the special pallet, A support post that supports the lower surface of the concave lane of the standard pallet may be provided, and an opening through which the support post is inserted may be provided in the special pallet. As a result, even if there is a difference in height between the support surface of the standard pallet and the support surface of the special pallet, the upper surface of each pallet can be mounted with a simple structure by supporting the special pallet with the support material and supporting the standard pallet with the support post. Can be flush with the floor.

  Since the present invention can flatten the fixed deck, the elevator deck, and the upper surface of the special pallet with the boarding floor by means as described above, the elevator system for barrier-free use that can be used by wheelchair users The parking device can be easily configured.

It is large enough to be installed vertically. The through hole 80 may be a hole that allows the upper end contact member 86 of the vertical post 85 to freely enter, such as a round hole or a square hole. Thus, in this embodiment, the special pallet 10 is formed by providing the cover plate 77 on the standard pallet 9. The special pallet 10 is also provided with a flange 74 at the lower four corners of the side rising portion 70, and a wheel 75 is pivotally supported on the flange 74. The wheels 75 traverse the shelf rail 7 of the parking shelf 8. Also in this special pallet 10, the lower surface of the ridge 74 is the lowermost surface.

  Thus, in this embodiment, the special pallet 10 is formed using the standard pallet 9, but in this case, the vehicle entry surface of both pallets 9, 10 (the standard pallet 9 is the concave lane 71. The upper surface of the special pallet 10 has a height difference of the height of the cover plate 77 (the depth of the concave roadway 71) to the height of the cover plate 77).

  Therefore, in this embodiment, the pallet end supporting means 81 that can support the pallets 9 and 10 in a preferable state is provided on the front and rear fixing portions (pit walls, floors, decks) of the loading portion 23. (FIG. 1).

  FIG. 7 is a perspective view of the holding means at the pallet end, and FIGS. 8A and 8B are front views showing the operation of the holding means at the pallet end with respect to the standard pallet, and FIGS. b) is a front view showing the operation of the holding means at the end of the pallet with respect to the special pallet.

  As shown in FIG. 7, the pallet end support means 81 provided at the front and rear fixing portions of the entry portion 23 is an elongated horizontal portion provided in a direction perpendicular to the entry direction at a predetermined height position in the pit. A material 82 (for example, a square pipe), a guide block 84 with an abutment plate 83 fixed to both ends of the horizontal material 82, and a predetermined erected slightly inward of the guide block 84 of the horizontal material 82 And a vertical post 85 having a length. An upper end contact member 86 is fixed to the upper end portion of the vertical post 85. The vertical post 85 is erected on a bracket 87 provided on the horizontal member 82. Further, the horizontal member 82 is supported by a bracket 89 on a column 88 of the fixed deck 30 provided in the pit 27. Further, the guide block 84 is formed in an arc shape from the left and right upper outer sides to the inner side. When the pallets 9 and 10 come into contact with the guide blocks 84, the pallets 9 and 10 are guided between the guide blocks 84. It is like that. The pallet end supporting means 81 is not provided with any drive source or the like.

  As shown in FIG. 8 (a), the standard pallet 9 lifted and lowered by the elevator 11 and supported at both ends by the pallet end supporting means 81 is placed on the plate 83 from the front fixed deck 31 (entry deck) shown in the figure. If the height is h0, the rod 74 of the wheel 75, which is the lowermost end of the standard pallet 9, is turned in a state of a height h1 that is a predetermined amount higher than the upper surface of the fixed deck 30.

  Then, as shown in FIG. 8 (b), when the swung standard pallet 9 is lowered, the lower surface of the concave road 71 comes into contact with and supports the upper end contact member 86 of the vertical post 85 at the final stage of the lowering. Is done. As a result, the upper surface of the concave road 71 becomes flush with the upper surface of the front fixed deck 31, that is, the boarding floor 29. At this time, even if the front and rear of the standard pallet 9 are bent by the vehicle weight, the front and rear ends of the standard pallet 9 can be made flat by lowering the swivel base 38 by a predetermined amount after the vertical posts 85 are supported. In this state, a gap of height h2 is formed between the collar 74 and the contact plate 83. The relationship between these heights is as follows: turning level h1> entry level h0> roadway depth (height when the kite is lifted from the plate) h2.

  On the other hand, as shown in FIG. 9 (a), the special pallet 10 lifted and lowered by the elevator 11 and supported at both ends by the pallet end supporting means 81 is in the same height h1 as the standard pallet 9 described above. Can be swiveled.

  Then, as shown in FIG. 9 (b), when the swung special pallet 10 is lowered, the vertical post 85 is loosely inserted into the through holes 80 provided in the left, right, front and rear portions of the special pallet 10. Then, the collar 74 descends while being guided by the arc surface of the guide block 84, and the lower end of the collar 74 rests on the contact plate 83 and is supported. As a result, the upper surface of the cover plate 77 is flush with the upper surface of the front fixed deck 31, that is, the boarding floor 29. At this time, even if the front and rear of the special pallet 10 are bent by the vehicle weight, the swivel base 38 can be made flat by lowering the swivel 38 by a predetermined amount after the flanges 74 at both ends of the special pallet 10 are supported by the contact plate 83.

  Accordingly, the standard pallet 9 having different heights of the entry surface (the standard pallet 9 is the upper surface of the concave roadway 71 and the special pallet 10 is the upper surface of the cover plate 77) without providing a power source in the pallet end supporting means 81 described above. Even if the special pallet 10 is mixedly loaded, the standard pallet 9 can be supported at a predetermined height and the special pallet 10 can also be supported at a predetermined height. As described above, the stop position of the elevator lifting frame 35 and the pallet lifting height h1 (turning level) in the entry portion 23 are the same for both the standard pallet 9 and the special pallet 10, but the pallet is lowered by 90 ° after turning. The distance to be floored is (h1-h2) in the standard pallet 9, whereas the special pallet 10 is different in h1 by the thickness h2 of the cover plate 77 in the special pallet 10. It is possible to physically include the loading level at the end of the pallet in accordance with the height of the respective loading surfaces with a simple mechanism without providing the above.

  Accordingly, by allowing the end portions of the standard pallet 9 and the special pallet 10 to be supported by different configurations of the pallet end supporting means 81, the configuration of the pallets 9 and 10 can be changed only partially, and the elevator 11 can be related. The standard pallet 9 and the special pallet 10 can be mixedly loaded without changing the configuration.

  FIG. 10 is a perspective view of a sensor using visible light in the entry portion.

FIG. 15 is a plan view of the entry portion at the time of warehousing in FIG. 14e. A procedure for a wheelchair user to enter the elevator type parking apparatus 1 will be described based on these drawings and the above-described drawings. In the following description, a case will be described in which a low-height vehicle M2 (for example, a sedan normal vehicle) of a wheelchair user contractor is received.

  As shown in FIG. 11 described above, the wheelchair user U2 stops the low vehicle height vehicle M2 in front of the entrance / exit 24 and operates the remote control transmitter 110 from the inside of the vehicle toward the entrance / exit 24 (three-sided frame). Then, a call signal of the contracted special pallet 10 for wheelchair is transmitted (two-dot chain line in FIG. 11). As shown in FIG. 13, when the receiver 129 receives this signal, the control device 131 specifies the current storage shelf position of the wheelchair-specific special pallet 10 contracted based on the received information, and calls the special pallet 10. Command the operation.

  By the command of the control device 131, as shown by a two-dot chain line in FIG. 1, the elevator 11 moves up and down to reach the position of the parking shelf 8 (the seventh stage on the left side) where the target special pallet 10 is stored. The special pallet 10 is pulled into the lift frame 35 and mounted by the operation of the pallet transfer mechanism (pallet lifting and turning drive mechanism 21). Thereby, the wheel 75 of the special pallet 10 is transferred onto the traverse rail 37 provided in the raising / lowering frame 35 (FIG. 4).

  Thereafter, as shown in FIG. 14a, the elevator 11 descends, starts to decelerate near the entrance, and when the lower part of the lifting frame 35 enters the pit 27 a little, as shown in FIG. The extension operation of the rod 43 is started, the swivel base 38 is raised, and the special pallet 10 is gradually lifted. At this time, the wheel 75 of the special pallet 10 is slightly detached from the traverse rail 37 but is still locked in the non-turning state.

  Then, as shown in FIG. 14 c, as the elevator 11 descends in the pit 27, the deck plate 66 of the two front and rear elevator decks 65 protrudes from the fixed deck 30 of the entry portion 23. The upper surface of the elevator deck 65 is naturally aligned with the surrounding fixed deck 30 and the entrance floor 29. Thereafter, the elevator 11 further descends and stops at a predetermined lowest position. At this time, the hydraulic cylinder 39 finishes the maximum extension operation, and the swivel base 38 and the special pallet 10 are lifted to a swivel level above the elevator deck 65 and the surrounding fixed deck 30 and are in a state of being capable of swiveling.

  Then, as shown in FIG. 14d, the special pallet 10 is turned 90 ° in the entry direction by turning the turntable 38 90 °. As shown in FIG. 14e, the swivel base 38 and the special pallet 10 are integrally lowered by a predetermined distance by the rod shortening operation of the hydraulic cylinder 39, and the flat surface on the upper surface of the special pallet 10 is the elevator deck 65 and the surrounding fixed deck 30. And stop when it becomes flush with boarding floor 29. In this figure, a vehicle M2 and a wheelchair user U2 described later with reference to FIG. 15 are shown.

  During the lowering operation, as shown in FIGS. 9 (a) and 9 (b), the vertical post 85 of the pallet end supporting means 81 is loosely inserted into the through hole 80 of the special pallet 10 so that the special pallet 10 Four wheel rods 74 are placed on the contact plate 83 of the horizontal member 82. As a result, even if the front and rear ends of the special pallet 10 are bent due to the weight of the vehicle, the pallet end is supported by the abutment plate 83 even when the entire pallet is bent in an arc shape. The alignment of the deck top surface, fixed deck top surface, boarding floor surface is physically ensured.

  As shown in FIG. 15, when the special pallet 10 is set in the state shown in FIG. 14e, the door 25 of the entrance / exit 24 is opened, and the sensor 95 (PH5) and the sensor 96 (PH6) are turned on to make visible light. 98 is irradiated. Also, the admission detection sensor 91 (PH1), the vehicle rear protrusion detection sensor 92 (PH2), the actual vehicle detection sensor 93 (PH3), and the vehicle front protrusion detection sensor 94 (PH4) are turned on.
