  The best mode for carrying out the present invention will be described below with reference to the drawings.

  FIG. 1 shows the relationship between the parking apparatus main body and the turntable.

  In FIG. 1, 1 is a parking device body, 2 is an entry / exit space, 3 is an entry / exit door of the parking device body 1, 4 is a turntable, and 5 is a vehicle.

  A vehicle detector is provided for a wall surface that is close to the rotation center of the turntable 4 and that may come into contact when the vehicle 5 placed on the turntable 4 rotates.

  In FIG. 1, the case where the vehicle detectors 8 and 9 are provided with respect to the two wall surfaces 6 and 7 is shown. In the figure, an optical detector is shown.

  The vehicle detectors 8 and 9 will be described with reference to FIGS. Since the vehicle detector 8 and the vehicle detector 9 are the same, the vehicle detector 8 will be described below.

  Supports 11 and 12 are erected at the corners of the wall surface 6 along the wall surface 6. That is, the vehicle detector 8 and the vehicle detector 9 are provided in a dead space of the entry / exit space 2 that is out of the region where the vehicle 5 rotates.

  The column 11 and the column 12 are different in height, the column 11 is high, and the column 12 is low. A lower flange 11a, an upper flange 11b, a lower flange 12a, and an upper flange 12b are provided at the lower and upper ends of the columns 11, 12, respectively, and are fixed to the floor surface via the lower flanges 11a, 12a.

  A sensor mounting bracket 15 is provided on one of the columns 11, 12, for example, the upper flange 11 b of the column 11, a projector 16 is mounted on the sensor mounting bracket 15, and the upper side of the other column 12 is positioned above the upper column 11. A light receiver 17 is attached to the flange 12b via a sensor mounting bracket 15.

  The sensor mounting bracket 15 has, for example, an L shape, and the holes 18 for mounting the projector 16 and the light receiver 17 are elongated holes that are long in the vertical direction. A hole 19 for attaching to the upper flanges 11 b and 12 b is a long hole that is long in the direction perpendicular to the sensor attachment surface 21. Therefore, the position of the light projector 16 and the light receiver 17 can be adjusted in the horizontal and vertical directions.

  As for the hole 18, one may be a circular hole and the other may be an arc centered on the circular hole so that the inclination of the projector 16 and the light receiver 17 to be attached can be adjusted.

  The mounting position and posture of the projector 16 are adjusted and installed so that the light projecting optical axis of the projector 16 and the light receiving optical axis of the light receiver 17 coincide.

  Detection light is emitted from the light projector 16, and the positions of the light projector 16 and the light receiver 17 are adjusted so that the detection light is received by the light receiver 17. The optical axis 23 of the detection light is set parallel to the wall surface 6 at a required interval d, and the light projector 16 and the light receiver 17 are inclined because they have different heights.

  Therefore, when the vehicle 5 placed on the turntable 4 rotates, if there is a portion that protrudes from the optical axis 23 toward the wall surface 6 in the range of height h in FIG. 23, the light receiver 17 detects that the optical axis 23 is cut off, that is, non-detection of the detection light. The height h is set so as to include the protruding portions of the vehicles of all vehicle types stored in the parking apparatus main body 1.

  Further, the distance d has a sufficient value so that the protruding portion of the vehicle 5 does not contact the wall surface 6 when the optical axis 23 is cut off.

  Next, FIG. 4 is a block diagram showing a control system in the parking apparatus of the present invention, in which 24 is a control device, 25 is an operating device, and 26 is an alarm device.

  The control device 24 rotates the turntable 4 in accordance with a turntable rotation command from the operation device 25. Further, when the signal from the vehicle detectors 8 and 9, that is, the non-light receiving signal from the light receiver 17 is inputted, the control device 24 makes the turntable 4 emergency stop.

  Further, the control device 24 maintains an emergency stop state with respect to the rotation of the turntable 4 in a direction in which the protruding portion that cuts off the optical axis 23 approaches the wall surface 6, and against the rotation in the reverse direction. In this case, the stop state is released.

  When the control device 24 makes an emergency stop, the alarm device 26 is driven to generate a warning sound or turn on and display an emergency stop lamp to give the operator information on emergency stop.

  In the case of an emergency stop, the operator operates the operating device 25 to rotate the turntable 4 in the reverse direction. Even if the operator mistakenly operates the turntable 4 in the direction in which the protruding portion approaches the wall surface 6, the emergency stop state is maintained.

  FIG. 5 shows another example of the vehicle detector 8 and the vehicle detector 9.

  The light projectors 16 are provided at predetermined intervals in the vertical direction, the light receivers 17 are provided in the vertical direction at the same pitch as the mounting pitch of the light projectors 16, and the light receivers 17 are shifted downward by one step with respect to the light projectors 16. Accordingly, each optical axis 23 is inclined by the mounting pitch.

  Thus, by providing a plurality of the light projectors 16 and the light receivers 17, it is possible to detect the protruding portion of the vehicle 5 more reliably and over a wide range.

  As shown in FIG. 6, if the mounting pitch of the projector 16 and the light receiver 17 is made fine, the projector 16 and the light receiver 17 may be installed so that the optical axis 23 is horizontal.

  As a light source of the projector 16, a phototube or a laser diode is used. The light projector 16 may emit a screen-like light beam as a detection light instead of a dot light beam, and the light receiving side may receive light by the plurality of light receivers 17.

  In addition, the light projector 16 and the light receiver 17 are installed via the support column 11 and the support column 12, but may be installed directly on the wall surfaces 6 and 7.

  The vehicle detectors 8 and 9 are provided on the wall surface 6 and the wall surface 7, respectively. However, if one wall surface 7 has a space, a vehicle detector is provided only on the wall surface 6. Also good.

  According to the present invention, since the projecting portion of the vehicle 5 comes into contact with the wall surfaces 6 and 7 or the emergency stop of the turntable 4 before colliding, the contact between the vehicle 5 and the wall surfaces 6 and 7, Collisions can be prevented. Moreover, since the light projector 16 and the light receiver 17 are provided in the dead space of the entrance / exit space 2, they can be installed in an existing parking device.
