  The present invention relates to a three-dimensional parking apparatus, and more particularly, to a three-dimensional parking apparatus that can be used not only as a parking lot but also as a vehicle exhibition hall.

  2. Description of the Related Art Conventionally, a multilevel parking lot that parks many vehicles in a limited plane space is known. For example, as shown in FIGS. 4 (A) and 4 (B), the three-dimensional parking lot is provided with lifts 101 and 102 provided in front of the vehicle entrance and for moving the lifts 101 and 102 in the vertical direction. The hoistway 103, 104, and a plurality of parking shelves 105, 106 provided in layers in the vertical direction on both sides of the hoistway 103, 104, are arranged in the hoistway 103, 104 when the vehicle enters and exits. There is known an elevator type multi-story parking apparatus that can be lifted up and down or moved back and forth and left and right to carry out the vehicle from each parking shelf in a state where the vehicle is mounted on a pallet (see, for example, Patent Document 1). .) Moreover, in such an elevator type three-dimensional parking apparatus, there is also known an apparatus that performs a vehicle entry / exit operation by inserting a comb type grating provided on a slide frame of a fork device into a comb type grating of a car storage cell. (For example, refer to Patent Document 2).

  Also, as shown in FIG. 4 (C), it has a large number of car shelves 111 juxtaposed in a grid pattern, and a four-way transport mechanism that transports pallets to the front, rear, left and right of each car rack, and is one less than the number of car shelves.

  However, in the elevator type three-dimensional parking apparatus disclosed in the background art and the flat puzzle type parking apparatus disclosed in Patent Document 3 and Patent Document 4, a vehicle is placed on a pallet or a slide frame in a parking space. There is a difficulty in requiring a large-scale transfer device for transfer. Furthermore, with such a parking device, it is difficult to efficiently observe all parked vehicles, and it is not suitable for a vehicle exhibition hall.

  In addition, in the multi-layer circulation type multi-story parking apparatus disclosed in Patent Document 5 described in the background art, a gondola is required for each vehicle, and the gondola is suspended by a one-point support method. There was a difficulty in becoming stable. Furthermore, such a parking device is intimidating like a ferris wheel and unsuitable for a vehicle exhibition hall.

  The present invention has been made to solve such a conventional difficulty, and includes a parking slope for parking a vehicle, and after the vehicle has entered the parking slope from the entrance of the vehicle, the vehicle is moved from its entry position. It is an object of the present invention to provide a three-dimensional parking apparatus that can be moved in the vertical direction and the rotation direction without being moved on the parking slope.

  A three-dimensional parking apparatus that achieves the above-described object includes a parking case that is formed in a cylindrical shape and provided with a spiral parking slope along the longitudinal direction for parking the vehicle in the cylinder, and both longitudinal ends of the parking case. A feed screw mechanism comprising a nut fixed to each part, a feed screw shaft that penetrates both ends and is screwed into two nuts, and an axial direction of the feed screw shaft of the feed screw mechanism is arranged in the vertical direction A pedestal that rotatably supports the feed screw shaft, a drive mechanism that rotates the feed screw shaft supported by the pedestal in the forward and reverse directions, and a rotation of the parking case when the feed screw shaft is rotated by the drive mechanism. And a rotation restricting mechanism that raises and lowers the parking case by the screw action of the feed screw shaft and the two nuts.

  According to such a three-dimensional parking apparatus according to the first aspect, when the feed screw shaft is rotated by the drive motor of the drive mechanism in a state where the rotation of the parking case is restricted by the rotation restricting mechanism, the parking case does not rotate. Since the two nuts move along the spiral groove of the feed screw shaft, the parking case can be moved in the vertical direction without rotating. Also, if the feed screw shaft is rotated by the drive motor of the drive mechanism without restricting the rotation of the parking case by the rotation restricting mechanism, the two nuts follow the spiral groove of the feed screw shaft. Therefore, the parking case can be rotated without moving up and down. Therefore, when the vehicle is parked in an empty space on the parking slope, it can be achieved by simply moving the parking case up and down and rotating it with respect to the vehicle entrance / exit where the vehicle to be parked is located. Even when a plurality of vehicles parked on the parking slope of the case are displayed, this can be achieved simply by raising and lowering and rotating the parking case.

  According to a second aspect of the present invention, in the multilevel parking apparatus according to the first aspect, the parking slope of the parking case is formed in a step shape.

  According to the three-dimensional parking apparatus which is such a 2nd aspect, it becomes possible to park a vehicle on a parking slope in a horizontal state.

  The third aspect of the present invention is the multilevel parking apparatus according to the first aspect, wherein the pedestal is fixed to the lower end portion of the feed screw shaft, the horizontal disk whose center of rotation is concentric with the feed screw shaft, and the horizontal disc A support body in which a concave portion is formed which is disposed below the horizontal disc and into which the horizontal disc is fitted, and a rolling element which is rotatably incorporated between the bottom surface of the concave portion of the support main body and the horizontal disc and supports the horizontal disc And a support member that is provided between the bottom surface of the concave portion of the support body and the horizontal disk, and makes the rotation center of the horizontal disk a fixed position within the concave portion of the support body.

  According to such a three-dimensional parking apparatus according to the third aspect, the rolling element is interposed between the horizontal disk and the bottom surface of the concave portion of the support body, and the rotation center of the horizontal disk is supported by the support member. Since the horizontal disk can move stably on the bottom surface of the recess of the support body, the feed screw shaft fixed to the horizontal disk can also rotate stably. Can exercise. Therefore, the parking case can be moved up and down and rotated in a stable state.

  A fourth aspect of the present invention is the multi-story parking apparatus according to the first aspect, wherein the drive mechanism is fixed to the lower end portion of the feed screw shaft and the spur gear whose center of rotation is concentric with the feed screw shaft and the spur gear. And a drive motor that drives the pinion gear.

  According to the three-dimensional parking apparatus according to the fourth aspect as described above, the power of the drive motor can be transmitted to the spur gear with an accurate speed ratio through the pinin gear with high efficiency, so that the rotational motion of the drive motor is parked. It becomes easy to convert to the number of rotations and torque required on the case side.

  According to a fifth aspect of the present invention, in the multi-story parking apparatus according to the first aspect, the rotation restricting mechanism is disposed along the recess member provided along the vertical direction of the outer periphery of the parking case and the outer periphery of the parking case. A lock mechanism having a lock pin that can be freely inserted into and removed from the recess of the recess material is provided.

  According to the three-dimensional parking apparatus according to the fifth aspect as described above, the lock mechanism can regulate the rotation of the parking case by fitting the lock pin into the recess of the recess material. By removing the lock pin from the recess, the rotation restriction of the parking case can be released.

  A sixth aspect of the present invention is the three-dimensional parking apparatus according to the first aspect, wherein the rotation restricting mechanism is a parking case spur gear provided at the bottom of the parking case so as to rotate concentrically with the parking case, and the parking case. A parking case pinion gear that is screwed to the spur gear, a parking case drive motor that drives the parking case pinion gear, and a support mechanism that supports the parking case drive motor so as not to rotate in synchronization with the parking case. It is what it has.

  According to the three-dimensional parking apparatus according to the sixth aspect as described above, the parking case pinion gear prevents the parking case spur gear from rotating by stopping the parking case drive motor, so that the rotation of the parking case is restricted. Since the parking case pinion gear rotates the parking case spur gear by driving the parking case drive motor, the parking case rotation restriction can be released. Therefore, this rotation restricting mechanism can perform the raising / lowering movement and the rotating movement of the parking case simultaneously or individually.

  According to the three-dimensional parking apparatus of the present invention, after a vehicle is entered into the parking slope from the entrance of the vehicle without using a large transfer device to transfer the vehicle to the parking space with a pallet, a car storage cell or a gondola. The vehicle can be moved in the vertical direction and the rotation direction with a simple structure without moving the vehicle from the approach position on the parking slope. Therefore, it is possible to install at a low cost and the safety is enhanced. Further, when a parking case is rotated in a state where a plurality of exhibition vehicles are parked on a spiral parking slope, it can be used as an advertising tower for a vehicle showcase having a high impact.

  The best mode for carrying out the three-dimensional parking apparatus of the present invention will be described below with reference to the drawings.

  As shown in FIGS. 1A and 1B, the three-dimensional parking apparatus of the present invention is formed in a cylindrical shape, and a spiral parking slope 21 for parking a vehicle in the cylinder is provided along the longitudinal direction L1. Of the parking case 2 and the nuts 31 and 32 fixed to both ends 2a and 2b in the longitudinal direction L1 of the parking case 2 and the feed that passes through both ends 2a and 2b and is screwed into the two nuts 31 and 32 A feed screw mechanism 3 including a screw shaft 33; a pedestal 4 in which the axis direction of the feed screw shaft 33 of the feed screw mechanism 3 is arranged in the vertical direction L1 and the feed screw shaft 33 is rotatably supported; The drive mechanism 5 that rotates the supported feed screw shaft 33 in the forward and reverse directions by the drive motor 53, and the rotation of the parking case 2 when the drive mechanism 5 rotates the feed screw shaft 33, the feed screw shaft 33 is regulated. And two na By screw action of bets 31 and a rotation restricting mechanism 6 for raising and lowering the car case 2. The parking slope 21 of the parking case 2 is formed in a spiral shape so that the plan view draws a circle.

  As shown in FIG. 2A, the parking case 2 is provided with a fall prevention fence 22 spirally along the outer periphery of the spiral parking slope 21 so that the parked vehicle does not fall from the parking slope 21. . Further, the fall prevention fence 22 is provided with an entrance / exit opening 22 a for taking in and out the vehicle from the outside of the parking case 2. The entrance / exit opening 22 a can be determined based on the number of vehicles that can be parked on the parking slope 21. The height of the fall prevention fence 22 is not particularly limited, and may be set to any height as long as the vehicle parked on the parking slope 21 does not fall. Furthermore, the parking slope 21 may be formed in a staircase shape. By forming the parking slope 21 in a staircase shape, the parking slope 21 can park the vehicle in a horizontal state.

  As shown in FIGS. 1A and 1B, the feed screw mechanism 3 is a motion conversion mechanism that converts the rotational motion of the feed screw shaft 33 into linear motion of the parking case 2 via two nuts 31 and 32. When the feed screw shaft 33 is rotated in a state in which the parking case 2 is not rotated by a rotation restricting mechanism 6 described later, the two nuts 31 and 32 are formed in a spiral shape of the feed screw shaft 33 because the parking case 2 does not rotate. Since it moves along the groove, the parking case 2 can be moved in the vertical direction L1 without rotating.

  As shown in FIG. 1C, the pedestal 4 is fixed to the lower end portion of the feed screw shaft 33 and is disposed below the horizontal disc 41 and a horizontal disc 41 whose center of rotation is concentric with the feed screw shaft 33. A support main body 42 having a recess 42a into which the horizontal disk 41 is fitted, and a bottom face 42a 'of the recess 42a of the support main body 42 and the horizontal disk 41 are rotatably incorporated to support the horizontal disk. And a support member 44 provided between the bottom surface 42a 'of the recess 42a of the support main body 42 and the horizontal disk 41 and having the rotation center of the horizontal disk 41 in a fixed position within the recess 42a of the support main body 42. I have. The support member 44 is supported by providing a support shaft on one of the bottom surface 42 a ′ of the recess 42 a of the support body 42 and the horizontal disk 41, and providing a support shaft groove in which the support shaft is fitted on the other side. The center of rotation of the horizontal disk 41 can be set at a fixed position in the recess 42 a of the main body 42.

  According to the pedestal 4 configured as described above, the rolling element 43 is interposed between the horizontal disk 41 and the bottom surface 42 a ′ of the recess 42 a of the support body 42, and the center of rotation of the horizontal disk 41 is supported by the support member 44. Since the horizontal disk 41 can be stably rotated on the bottom surface 42a 'of the recess 42a of the support body 42, the horizontal disk 41 can be moved to a fixed position in the recess 42a of the support body 42. The feed screw shaft 33 fixed to can also make a stable rotational motion. The rolling mechanism of the pedestal 4 preferably has a structure such as a flat seat thrust bearing that is a rolling bearing. In this case, the rolling element 43 is preferably a plurality of balls or rollers made of, for example, metal or resin.

  As shown in FIGS. 1A and 1B, the drive mechanism 5 is fixed to the lower end portion of the feed screw shaft 33, and a spur gear 51 whose rotation center is concentric with the feed screw shaft 33, and the spur gear 51. The motor includes a pinion gear 52 and a drive motor 53 that drives the pinion gear 52. The spur gear 51 is located above the horizontal disk 41 of the pedestal 4. The pinion gear 52 is fixed to the rotating shaft 53 a of the drive motor 53. The drive motor 53 is fixed to a fixed system located in the vicinity. According to the drive mechanism 5 configured as described above, the power of the drive motor 53 can be transmitted to the spar gear 51 through the pinin gear 52 with high accuracy at a high speed ratio.

  As shown in FIGS. 1A and 1B, the rotation restricting mechanism 6 is provided with a recessed member 61 provided along the vertical direction L <b> 1 of the outer periphery of the parking case 2, and a recess disposed along the outer periphery of the parking case 2. A lock mechanism 60 having a lock pin 62 detachably fitted in the recess of the member 61 is provided. It is conceivable that the concave member 61 uses, for example, a grooved steel. Further, the lock mechanism 60 excluding the recessed member 61 is fixed to a fixed system. Further, the lock mechanism 60 may include a known electric device that drives the lock pin 62 so as to be detachable with respect to the recess of the concave member 61. According to the rotation restricting mechanism 6 configured as described above, the lock pin 62 is fitted into the recess of the recessed member 61 by the lock mechanism 60, whereby the rotation of the parking case 2 can be restricted. By removing the lock pin 62 from the recess of the member 61, the rotation restriction of the parking case 2 can be released. The number of the recessed members 61 is not limited to one, but may be provided at a plurality of locations. In FIGS. 1A and 1B, the recess members 61 are provided at three equal intervals.

  Operation | movement of 1 A of multistory parking apparatus comprised in this way is demonstrated. In addition, this three-dimensional parking apparatus 1A is a semi-underground structure, and the underground tube | pipe 7 for burying the parking case 2 in the hole dug underground is embed | buried. A drive box 8 for incorporating the pedestal 4 and the drive mechanism 5 is embedded under the underground tube 7, and a lock mechanism 60 is installed at the upper end of the underground tube 7. Further, on the ground, a vehicle entrance / exit 10 is installed at a predetermined position around the parking case 2 to allow the vehicle to enter and exit from the entrance / exit opening 22a of the parking case 2.

  In order to park the vehicle in the three-dimensional parking apparatus 1A, first, the parked vehicle is put on standby at the vehicle entrance 10. Then, the spur gear 51 via the pinion gear 52 is driven by the drive motor 53 of the drive mechanism 5 in a state in which the lock pin 62 of the lock mechanism 60 that is the rotation restricting mechanism 6 is fitted in the concave member 61 to restrict the rotation of the parking case 2. And the feed screw shaft 33 that can be smoothly rotated by the base 4 is rotated. When the feed screw shaft 33 rotates, the lock mechanism 60 is locked and the parking case 2 does not rotate. Therefore, the two nuts 31 and 32 move along the spiral groove of the feed screw shaft 33, so the parking case 2 rotates. For example, it moves upward without making it. Note that the lock pin 62 of the lock mechanism 60 also moves upward in the recess of the recessed member 61 provided along the vertical direction L1 of the outer periphery of the parking case 2.

  When the empty space of the parking slope 21 in the parking case 2 rises to the height of the vehicle entrance 10, the drive motor 53 is stopped at that time, and the parking slope 21 is stopped at that height. Then, the lock pin 62 of the lock mechanism 60 is removed from the recessed member 61, and the spur gear 51 is rotated again by the drive motor 53 via the pinion gear 52 to rotate the feed screw shaft 33. When the feed screw shaft 33 rotates, since the lock mechanism 60 is not locked, the two nuts 31 and 32 do not move along the spiral groove of the feed screw shaft 33. Case 2 can also be rotated. That is, the parking case 2 can be rotated while maintaining its height. When the empty space of the parking slope 21 in the parking case 2 rotates to the position of the vehicle entrance 10, the drive motor 53 can be stopped at that time, and the parking slope 21 can be stopped at the rotational position. The vehicle can be parked in an empty space on the parking slope 21.

  When the parking slope 21 has a small diameter in a plan view, as shown in FIG. 2B, if the side surface of the vehicle is parked along the outer periphery of the parking slope 21, the parking slope 21 efficiently moves the vehicle. It can be parked. Further, when the parking slope 21 has a large diameter in plan view and a large number of parked vehicles, the side surface of the vehicle is parked along the radiation extending radially from the rotation center of the parking case 2 as shown in FIG. Then, the vehicle can be parked efficiently on the parking slope 21. When the parking slope 21 is formed in a staircase shape, the vehicle can be parked in a horizontal state on the parking slope 21 by forming the parking slope 21 in a staircase shape along the arrangement of the vehicles.

  The rotation restricting mechanism 6 restricts the rotation of the parking case 2 when the drive mechanism 5 rotates the feed screw shaft 33, and the parking case 2 is driven by the screw action of the feed screw shaft 33 and the two nuts 31 and 32. Any mechanism can be used as long as it can be moved up and down. For example, a rotation regulating mechanism 9 as shown in FIGS. 3A and 3B can be adopted. Since the multi-story parking apparatus 1B that employs the rotation restricting mechanism 9 is the same element as the multi-story parking apparatus 1A except for the rotation restricting mechanism 9, the same elements are denoted by the same reference numerals and description thereof is omitted.

  The rotation regulating mechanism 9 includes a parking case spur gear 91 provided on the bottom 2b of the parking case 2 so as to rotate concentrically with the parking case 2, and a parking case pinion gear 92 that is screwed into the parking case spur gear 91. And a parking case drive motor 93 that drives the parking case pinion gear 92 and a support mechanism 94 that supports the parking case drive motor 93 so as not to rotate in synchronization with the parking case 2.

  The parking case pinion gear 92 is fixed to a rotating shaft 93 a of the parking case drive motor 93. The support mechanism 94 includes a motor moving case 94a that linearly moves the parking case drive motor 93 along the longitudinal direction L1 of the parking case 2. The motor moving case 94a moves the parking case drive motor 93 to the motor. A slide mechanism (not shown) that guides in the vertical direction L1 along the inside of the case 94a is provided. According to the support mechanism 94 configured as described above, the parking case drive motor 93 is stopped so that the parking case pinion gear 92 prevents rotational movement of the parking case spur gear 91, so that the rotation of the parking case 2 is restricted. Since the parking case pinion gear 92 rotates the parking case spur gear 91 by driving the parking case drive motor 93, the rotation restriction of the parking case 2 can be released. Therefore, the rotation restricting mechanism 9 can perform the raising / lowering motion and the rotating motion of the parking case 2 simultaneously or individually.

  Operation | movement of the multi-story parking apparatus 1B comprised in this way is demonstrated. Since the semi-underground structure is the same as that of the three-dimensional parking apparatus 1A, the underground tube 7 and the drive box 8 are embedded, and the vehicle doorway 10 is installed in the entrance / exit opening 22a of the parking case 2. However, the underground tube 7 is provided with a motor moving case 94a, which is a support mechanism 94, along the longitudinal direction L1.

  In order to park the vehicle in the three-dimensional parking apparatus 1B, first, the parked vehicle is put on standby at the vehicle entrance 10. Then, in a state where the parking case drive motor 93 of the rotation restricting mechanism 9 is stopped, the spur gear 51 is rotated by the drive motor 53 of the drive mechanism 5 via the pinion gear 52 and can be smoothly rotated by the base 4. The shaft 33 is rotated. When the feed screw shaft 33 is rotated, the parking case pinion gear 92 of the rotation restricting mechanism 9 is prevented from rotating the parking case spur gear 91, so that the two nuts 31 and 32 are formed in the spiral groove of the feed screw shaft 33. Therefore, the parking case 2 moves upward, for example, without rotating. The parking case drive motor 93 also moves upward in the motor moving case 94a of the support mechanism 94 provided along the vertical direction L1 of the outer periphery of the parking case 2.

  When the empty space of the parking slope 21 in the parking case 2 rises to the height of the vehicle entrance 10, the drive motor 53 is stopped at that time, and the parking slope 21 is stopped at that height. And the parking case 2 maintains its height by rotating the parking case 2 by rotating the parking case spur gear 91 via the parking case pinion gear 92 by the parking case drive motor 93 of the rotation regulating mechanism 9. It can be rotated as it is. When the empty space of the parking slope 21 in the parking case 2 rotates to the position of the vehicle entrance 10, the parking case drive motor 93 can be stopped at that time, and the parking slope 21 can be stopped at that rotational position. The vehicle can be parked in the empty space of the parking slope 21 from the entrance 10.

  When any of the three-dimensional parking apparatuses 1A and 1B is used as an exhibition hall, a vehicle parked on the parking slope 21 in the fall prevention fence 22 of the parking case 2 can be viewed from the outside of the parking case 2. A transparent material may be used for the fall prevention fence 22 so that it can be made. In this case, the multi-story parking apparatus 1A has an exhibition function of displaying the exhibition vehicle by constantly rotating the parking case 2 according to the height at which the parking case 2 is to be displayed or by raising and lowering the parking case 2. Yes. In addition, when the parking case 2 is raised and lowered, the three-dimensional parking apparatus 1A cannot be rotated because the raising and lowering mechanism and the rotation mechanism are associated with each other. On the other hand, the multi-story parking device 1B has a display function of rotating the parking case 2 while moving up and down, in addition to the display function of the multi-story parking device 1A, because the rotation mechanism and the lifting mechanism are not associated with each other. .

  Further, in the multi-story parking apparatus 1B, the number of teeth of the parking case spar gear 91 and the feed screw so that the parking case 2 can be raised and lowered by one pitch of the screw of the feed screw shaft 33 while the parking case 2 makes one rotation by the parking case spar gear 91. If the distance between the pitches of the shafts 33 is set, the parking case 2 can be lifted and lowered slowly, which is suitable for vehicle display.

  Therefore, in the case of parking a vehicle in an empty space on the parking slope, the three-dimensional parking apparatus of the present invention only moves the parking case in the vertical direction and rotates it with respect to the vehicle entrance / exit where the vehicle for parking is located. In addition, when a plurality of vehicles parked in advance on the parking slope of the parking case are displayed, the vehicle can be achieved only by raising and lowering and rotating the parking case. Furthermore, since a vehicle can be exhibited without moving a plurality of gondola along a frame installed on the ground, it can be used as a vehicle exhibition hall without intimidation.

  Although the present invention has been described with the specific embodiments shown in the drawings, the present invention is not limited to the embodiments shown in the drawings, and is known so far as long as the effects of the present invention are achieved. It goes without saying that any configuration can be adopted.
