JP 2004-224462 A

  Since the position of the car stop device in the car elevator disclosed in Patent Document 1 on the car floor is fixed, an operation of moving the car forward or backward relative to the car stop device to stop it at an accurate position is necessary. For those who are not very good at it, there are some drivers who are bothered by this operation.

  An object of the present invention is to provide an automobile elevator capable of reliably stopping a vehicle without requiring an accurate stop position of the vehicle in a car.

  An elevator for an automobile according to the present invention includes a car stop device installed on a car floor near each door in a car having front car doors and rear car doors that are driven to open and close, and a control device that controls the car stop devices. Each car stop device has a car stop member that can be moved up and down between the car floor protruding position and the car floor storage position by the first drive means, and the car stop member is moved by the first drive means. After moving to the floor protruding position, the second drive means can move horizontally toward the car center position toward the center of the car to the car stop position.

  In the automobile elevator according to the present invention, it is preferable that the control device controls the car stop device so that the car stop member is moved from the car stop position to the car floor storage position through the car floor protruding position after the car door is opened.

  Further, in the automobile elevator according to the present invention, the guide member that guides the car stopper member when the car stopper member horizontally moves from the car floor protruding position to the car stop position, the main guide rail laid on the car floor, and the first guide rail When the car stop member is moved upward to the car floor projecting position by the driving means, it is constituted by a divided guide rail provided continuously with the main guide rail. The car guide member is provided on the divided guide rail by the second drive means. A roller to be rotationally driven is placed, and roller detection means for detecting a state where the roller is placed may be arranged on the divided guide rail.

  Further, in the automobile elevator according to the present invention, the second drive means is a motor, and the control device reaches the vehicle stop position where the vehicle stop member moved from the car floor protruding position to the car center side contacts the vehicle tire. This may be detected by a change in the motor current and the driving of the motor may be stopped.

  Furthermore, in the automobile elevator according to the present invention, a retaining member having a lower portion wider than the upper portion is fixed to the lower surface of the vehicle retaining member, and when the vehicle retaining member moves horizontally from the protruding position on the car floor, the retaining member It is preferable that the retaining member moves along a retaining groove that has substantially the same shape and has a slightly larger cross section and extends to the car floor.

  According to the automobile elevator according to the present invention, the vehicle stoppers in which the vehicle stopper members protruding on the car floor from the vehicle stopper devices provided on the car floors near the front and rear car doors horizontally move toward the center of the car and come into contact with the tires of the automobile. Since the vehicle can reach the position, it is possible to reduce the burden on the driver without requiring an accurate stop position of the vehicle in the car, and by a vehicle stop member that contacts the front of the front wheel and the rear of the rear wheel. For example, the movement of the automobile in the car during the car raising / lowering operation or the door opening / closing operation can be reliably prevented. As a result, it is possible to reliably prevent the automobile from colliding with the car door and causing the door to be deformed or damaged, or the door opening / closing failure due to the deformation of the door guide shoe.

  Embodiments according to the present invention will be described below in detail with reference to the accompanying drawings. In this description, specific shapes, materials, numerical values, directions, and the like are examples for facilitating the understanding of the present invention, and can be appropriately changed according to the application, purpose, specification, and the like.

  FIG. 1 is a diagram schematically showing an automobile elevator (hereinafter referred to as “elevator”) 10 according to an embodiment of the present invention. The elevator 10 includes a car 16 disposed in a hoistway 14 that extends in the vertical direction in a parking building 12 having a plurality of parking floors. The car 16 is moved up and down in the hoistway 14 by winding or unwinding a wire rope connected to the upper part by a hoist according to a well-known technique. In FIG. 1, the car 16 is shown in a state of landing on the first floor.

  An outer landing door 20 that can be opened and closed is installed at the landing 18 located on the first floor of the parking building 12. The outer landing door 20 is a door that opens and closes in a double-opening or single-opening manner in the lateral direction in conjunction with the car door 24 installed in the car 16. The car 1 that has arrived at the landing 18 gets into the car 16 with the outer landing door 20 and the car door 24 open, but after that, the car 1 gets into the car 16 from the state shown in FIG. For the sake of convenience, the direction in which the front of the automobile 1 faces is referred to as “front”, and the direction in which the rear of the automobile 1 faces is referred to as “rear”.

  The car 16 is provided with a front car door 22 and a rear car door 24 on both wall surfaces facing the getting-on / off direction A of the automobile 1. Each of the car doors 22 and 24 is opened and closed in a double-opening or single-opening manner in the lateral direction by a door opening / closing drive unit (not shown) installed on the car 16.

  On the other hand, in the parking building 12, the first floor parking lot 26 and the second floor parking lot 28 are provided with a first floor landing door 30 and a second floor landing door 32 respectively facing the hoistway 14. Each floor landing door 30 is configured to open and close in conjunction with the front car door 22 of the car 16 landing on the floor. In addition, when the entrance to the first floor parking lot 26 is separately provided in the parking building 12, the first floor landing door 30 is not necessarily provided.

  A car operation panel 34 including a destination floor registration button, a door opening / closing button, an emergency intercom, and the like is disposed on the side wall of the car 16. In the car 16, a car stop device 38 is installed on the car floor 36 near the front car door 22 and the rear car door 24. The car operation panel 34 is usually installed on the front side wall (not shown in FIG. 1) corresponding to the right-hand drive vehicle in Japan, but may be installed on the opposite side walls. .

  FIG. 2 is a plan view showing the car stopper device 38 as viewed from above the car 16, and FIG. 3 is a cross-sectional view taken along the line BB in FIG. The two car stop devices 38 provided at the front and rear positions of the car 16 have the same configuration except that the horizontal movement direction of the car stop member is reversed. Therefore, in FIG. 2, only the car stop device 38 on the front car door 22 side is provided. In FIG. 2, the lower side corresponds to the front car door 22 side, and the upper side corresponds to the car center side in the vehicle getting-on / off direction A. Moreover, in FIG. 3, although only the one end side of the vehicle stop apparatus 38 is shown, the other end side is also comprised similarly.

  The car stopper device 38 has a car stopper member 40 made of an elongated rectangular metal tube whose both end faces are closed. The car stopper member 40 is accommodated in an upper opening case portion 42 embedded and fixed in the car floor 36, and the upper surface is flush with the car floor 36 in the car floor storage position in the accommodated state. The vehicle stop member 40 has a length that is equal to or greater than the vehicle width of an automobile that can use the elevator 10, and has a height of about 10 cm in order to sufficiently exhibit the vehicle stop function. Further, the lower surface of the vehicle stopper member 40 may be opened over the entire width. In this case, a retaining member described later can be fixed to the upper surface in the retaining member 40.

  A motor 44 as a second driving means is built in the longitudinal end portion of the car stopper member 40. A roller 46 having a concave groove on the outer peripheral portion is connected to a rotation shaft 43 of a motor 44 that protrudes to the outside through a through hole formed in an end surface 41 of the car stopper member 40.

  The roller 46 is placed on a convex divided guide rail 48 having a length that can be stored in the width direction of the case portion 42 (same as the getting-on / off direction A). In the divided guide rail 48, a micro switch 49 is embedded as a roller detecting unit corresponding to the position where the roller 46 is placed. When the detection pin of the micro switch 49 is pushed in by the roller 46, it can be detected that the roller 46 exists on the divided guide rail 48 corresponding to the position of the micro switch 49. Note that the concave-convex relationship between the roller and the guide rail may be reversed. That is, it may be configured such that the roller fits into the concave guide groove formed in the guide rail.

  A support member 50 is fixed to the lower part of the division guide rail 48. One end of a lever 52 is rotatably connected to the support member 50. The other end of the lever 52 is rotatably connected to the side surface of the worm gear 54. The worm gear 54 meshes with a worm 58 that is connected to a rotating shaft of a motor 56 that is fixed to the bottom of the case portion 42. As the motor 56, a stepping motor capable of accurately controlling the rotation speed can be suitably used. The split guide rail 48 is engaged at both ends with a guide groove 60 formed by extending in the vertical direction on both inner wall surfaces of the case portion 42 facing each other, and is guided by the guide groove 60 during vertical movement. It is like that.

  With this configuration, the support member 50 and the divided guide rail 48 can be moved upward via the lever 52 by operating the motor 56 and rotating the worm gear 54 through the worm 58 in the direction of arrow U by a predetermined angle. As a result, the vehicle stop member 40 can be moved upward from the position in the car floor to the position on the car floor protruding as shown in FIG. A gap 62 is formed between the car stopper member 40 and the car floor 36 at the protruding position on the car floor in order to allow the horizontal movement of the car stopper member 40 described later. On the other hand, by rotating the motor 56 in the reverse direction and rotating the worm gear 54 by a predetermined angle in the direction of arrow D, the car stopper member 40 is moved downward from the car floor protruding position shown in FIG. 4 to the car floor storage position shown in FIG. be able to.

  Referring again to FIGS. 2 and 3, a main guide rail 64 extending from the car stopper 38 toward the center of the car is laid on the car floor 36. The main guide rail 64 has substantially the same cross-sectional shape as the divided guide rail 48, and the divided guide rail with respect to the main guide rail 64 when the vehicle stopper member 40 moves from the car floor storage position to the car floor protruding position. 48 is continuously provided through a slight gap. In this state, the motor 44 is operated to rotationally drive the roller 46 to move the roller 46 from the divided guide rail 48 to the main guide rail 64, so that the vehicle stopper 40 moves from the protruding position on the car floor toward the center of the car. To move horizontally. Here, the main guide rail 64 and the divided guide rail 48 constitute a guide member that guides when the vehicle stopper member 40 moves horizontally.

  A retaining block (a retaining member) 66 having a side trapezoidal shape in which the lower portion is wider than the upper portion is fixed to the lower surface of the vehicle stopper member 40. On the other hand, a retaining groove 68 is formed in the car floor 36 in parallel with the main guide rail 64. The retaining groove 68 is formed to have a trapezoidal transverse cross-sectional space that is substantially the same shape as the retaining block 66 and has an end portion that opens to the side wall of the case portion 42. As a result, when the car stop member 40 moves to the car floor projecting position, the retaining block 66 is in a position facing the opening of the retaining groove 68, and the car retaining member 40 moves horizontally along the main guide rail 64. Sometimes it can enter and move into the retaining groove 68. The engagement between the retaining block 66 and the retaining groove 68 prevents the vehicle retaining member 40 from floating upward from the car floor 36 and the roller 46 from being detached from the main guide rail 64, and is similar to the main guide rail 64. In addition, it also functions to guide the horizontal movement of the vehicle stop member 40.

  Note that the retaining block 66 and the retaining groove 68 are not limited to the shape as described above, but may have other shapes in which the lower portion is wider than the upper portion, for example, an inverted T shape. In addition, as shown in FIG. 2, car stop member detection means, for example, a micro switch 71, may be installed on the car floor 36 for detecting the excessive travel of the car stop member 40.

  As shown in FIG. 3, a control device 70 that controls the car stopper device 30 is disposed in the case portion 42. The control device 70 can include a CPU (Central Processing Unit), a memory, and the like, and has a function of reading and executing a control program stored in the memory. However, the control device 70 may be configured by an electric circuit that is hardware designed to realize the same control.

  As shown in FIG. 5, the control device 70 is connected to the motor 56, the motor 44, the roller detection switch 49, and the vehicle stop member detection switch 72, and the elevator operation panel that controls the car operation panel 34 and the elevator 10 as a whole. And an in-car scale device 74 that is installed on the car and measures the weight in the car. The control device 70 that controls the car stop device 38 may be incorporated as a part of the elevator control panel 72.

  Subsequently, the operation of the car stopper device 10 having the above-described configuration will be described with reference to FIGS.

  FIG. 6 is a flowchart showing a control process executed by the CPU of the control device 70. First, in a state where the outer landing door 20 and the rear car door 24 are open, it is determined whether or not the automobile 1 has entered the car 16 based on the output of the car scale device 74 (step S10). If it is determined that the car 1 is in the car 16 (YES in step S10), it is determined whether or not the driver has registered the destination floor on the car operation panel 34 (step S12).

  If it is determined that the destination floor has been registered (YES in step S12), the motor 56 is operated to move the car stop member 40 upward from the car floor storage position to the car floor protruding position, and then the motor 44 is operated to operate the roller. 46 is rotated and moved from the divided guide rail 48 to the main guide rail 64, whereby the vehicle stopper 40 is moved horizontally from the car floor protruding position to the car center side (step S14).

  Subsequently, as shown in FIG. 7, it is determined whether or not the front and rear vehicle stop members 40 have reached vehicle stop positions where they contact the front and rear tires 2 of the automobile 1, respectively (step S <b> 16). Here, the current of the motor 44 is detected and monitored by a sensor or the like, and it is determined that the vehicle stop member 40 is in contact with the tire 2 when the current value suddenly increases.

  As shown in FIG. 8, when it is determined that each vehicle stop member 40 is in contact with the front of the front tire 2 and the rear of the rear tire 2 (YES in step S16), the motor 44 is stopped. The horizontal movement of the vehicle stop member 40 is stopped (step S20).

  Thereafter, in the elevator 10, the car 16 moves up to the floor registered as the destination floor after the outer landing door 20 and the car door 24 are closed according to the control by the elevator control panel 72.

  Then, it is determined whether the car 16 has landed on the destination floor registered as the destination floor, for example, the second floor, and the door opening operation of the front car door 22 and the second floor landing door 32 has been completed (step S22). ). If it is determined that the door opening operation is completed (YES in step S22), the vehicle stopper 40 is housed in the car floor 36 by the reverse operation to that described above. That is, the car stop member 40 first moves horizontally from the car stop position to the protruding position on the car floor where the roller 46 is detected on the divided guide rail 48 by the operation of the motor 44, and then from the protruding position on the car by the operation of the motor 56. It moves downward to the floor storage position (step S24). As a result, the driver can drive the automobile 1 and remove it from the car 16.

  As described above, according to the elevator 10 including the car stop device 38 of the present embodiment, each car stop member protruding on the car floor 36 from the car stop device 38 provided on the car floor 36 in the vicinity of the front and rear car doors 22 and 24. Since the vehicle 40 moves horizontally to the center of the car and reaches the vehicle stop position where it abuts against the tire 2 of the car, the driver's burden is not required without requiring an accurate stop position of the car 1 in the car 16. The vehicle stopping member 40 that can be reduced and that contacts the front of the front wheel and the rear of the rear wheel of the vehicle 1 can reliably prevent the vehicle 1 from moving in the car 16 during the car lifting and lowering operation or the door opening and closing operation. . As a result, it is possible to reliably prevent the automobile 1 from colliding with the car doors 22 and 24 to cause deformation or breakage of the door or occurrence of door opening / closing failure due to deformation of the door guide shoe.

  Although one embodiment of the present invention has been described above, the present invention is not limited to the elevator 10, and various modifications and improvements can be made without departing from the technical scope of the present invention.

  For example, the first driving means for moving the vehicle stopper member up and down between the car floor storage position and the car floor protruding position is not limited to a combination of a gear and a lever, but may be a cam mechanism, a crank mechanism, a rack and pinion, or the like. These mechanical elements may be used, and the driving force generation source is not limited to the motor but may be an electromagnetic solenoid or the like.

  Further, in the above description, two tires are stopped by one vehicle stop member, but two vehicle stop members divided for each tire may be used.
