JP 2000-238571 A

  In the above-described conventional configuration, when the placement unit is moved from the external position to the storage position, after the movement of the placement unit is temporarily stopped when the placement unit is lifted to the raised position, Starting to slide the mounting part toward the inward position, and when moving the mounting part from the storage position to the external position, the slide movement in which the mounting part is moved to the outer position is the same. After the movement of the placement unit is stopped once the operation is finished, the placement unit is moved between the external position and the storage position to start lowering the placement unit toward the lowered position. In addition to taking a long time, a large impact is generated on the mounted body due to the raising and lowering of the mounting portion and the stop and start of the slide movement.

  The present invention has been made in view of the above circumstances, and its purpose is for a vehicle capable of suppressing an impact that occurs during the movement while quickly moving the mounting portion between the storage position and the external position. It is in providing a lifting device.

The vehicle lifting apparatus according to the present invention is configured to lift and lower a support frame that supports a mounting portion configured to be able to mount a mounting body, so that the above-described mounting portion is positioned on or below the ground and the vehicle. Elevating operation means for elevating and moving to an ascending position located on the floor surface of the vehicle, and the mounting portion described above at an outer position on the vehicle outer side and an inner position on the vehicle inner side with respect to the support. Slide operation means for sliding and moving in and out of the vehicle, lift position detection means for detecting the height of the support frame relative to the vehicle, slide position detection means for detecting the slide position of the mounting portion with respect to the support frame, Based on the detection of the lift position detection means and the slide position detection means, the mounting portion is moved up and down while being positioned at the outer position and is slid in and out of the vehicle while being positioned at the lift position. So that the lifting operation hand And a vehicle lifting device comprising a control means for controlling operation of moving the operating means is provided,
According to the first characteristic configuration, when the above-described placement unit that is raised in a state where the control unit is located at the outer position is raised to a slide start raising position before the raised position, Is started to slide up toward the inward position, and starts moving up and down before the mounting portion slides toward the outside of the vehicle while being positioned at the raised position. When the slide is moved to the slide position, the raising and lowering operation means and the operation of the slide operation means are controlled in such a manner that the placement portion starts to be lowered toward the lowered position. Features a point.

  That is, moving the mounting part up and down while moving it in and out of the vehicle and moving it up and down between the lowered position and the rising position, and sliding the mounting part in and out of the vehicle with respect to the support The slide is moved between the position and the inward position to move the placement unit between the storage position and the external position.When moving the placement unit from the external position to the storage position, Similarly, when starting the slide movement to move to the vehicle inward side before the ascent to stop moving, and moving the mounting part from the storage position to the external position, The time to move the mounting part between the external position and the storage position is shortened by starting the lowering to move the mounting table downward while moving the mounting base before the sliding movement to the side stops. What you can do Of course, when the lifting and sliding movements both have components that move in and out of the vehicle, and when the other stage is stopped or started during the movement of the other, the lifting or sliding movement of the mounting table is stopped and started Thus, it is possible to provide a vehicle lifting device that can suppress the impact generated during the movement while quickly moving the mounting portion between the storage position and the external position. .

  According to the second characteristic configuration, when the previous placing portion to be raised by the control means is raised to the raising position for deceleration before the raising position, the raising speed of the preceding placement portion is gradually increased to the set lower speed for raising. It is comprised so that the operation | movement of the said raising / lowering operation means and the said slide operation means may be controlled with the form to decelerate, and the said mounting part is in the middle of decelerating the raising speed of the said mounting part to the said setting low speed for a raising, or deceleration It is characterized by being configured so as to be raised to the slide start ascending position.

  That is, there is little impact when decelerating the ascending movement speed by gradually decelerating the ascending speed of the placing part to the set lower speed for raising, and when the placing part is stopped at the raised position, it is reduced to the set lower speed for raising. Since the vehicle is decelerated, the impact at the time of stopping is reduced, and the burden on the mounted object placed on the placing part can be reduced. In particular, when a wheelchair is placed as the mounted body, the ride comfort of the passenger riding on the wheelchair can be improved.

  According to a third characteristic configuration, when the above-described placement unit that the control unit slides toward the outside of the vehicle is slid to the deceleration slide position before the outside position, the slide moving speed of the above-described placement unit Is configured to control the operation of the lifting and lowering operating means and the slide operating means in a form that gradually decreases to a set low speed for sliding, and the mounting unit is configured to control the slide moving speed of the mounting unit for the sliding. The present invention is characterized in that it is configured to be slid and moved to the slide position for starting up and down during or after decelerating to a set low speed.

  In other words, the impact of slowing down the slide movement speed is reduced by gradually decelerating the slide movement speed of the placement section to the slide setting low speed, and when the placement section is stopped at the outer position, the slide setting speed is low. Since it is decelerated to speed, the impact at the time of a stop decreases, and the burden of the mounting body mounted in the mounting part can be reduced. In particular, when a wheelchair is placed as the mounted body, the ride comfort of the passenger riding on the wheelchair can be improved.

Stop ascending movement. This set time is set so that the ascending moving speed is longer than the deceleration from the set ascending speed to the ascending set low speed.

  The linkage between the sliding movement of the lifting platform 1 and the lifting movement will be described. When the lifting platform 1 to be lifted in the state of being located at the outer position is raised to the slide start rising position before the rising position, the lifting platform Ascending / descending stage 1 starts to slide toward the inward position and slides toward the outside of the vehicle in a state where it is positioned at the raised position. When it is slid and moved, the elevator 1 is started to be lowered toward the lowered position. The position where the elevator 1 is raised to the raised position and slid to the inner position with respect to the elevator frame 2 to store the elevator 1 in the vehicle is referred to as the storage position, and the elevator 1 is set to the lowered position. A position that is lowered and slid to an outward position with respect to the lifting frame 2 to place the lifting platform 1 on or near the ground outside the vehicle is referred to as an external position.

The slide position for starting up / down is set to the outer position side than the outer position for deceleration, and the lifting / lowering is performed at the same time or after the slide moving speed of the lifting platform 1 is decelerated to the set low speed for sliding. It is configured to be slid to the starting slide position.
Also, the slide start ascending position is set to an upper position side with respect to the deceleration upper position, and rises to the slide start ascending position while decelerating the ascending speed of the lifting platform 1 to the ascending set low speed. It is configured to be.

The linkage between the sliding movement of the lifting platform 1 and the lifting movement will be described based on the flowchart of FIG.
When the lowering button 54a of the pendant-type operation tool 54 is pushed and operated in a state where the lifting platform 1 is located at the storage position, the lifting platform 1 starts to slide toward the outer position, and the sliding movement speed is increased. Gradually increase to the set slide speed, and when the elevator 1 that slides toward the outer position at the set slide speed slides to the outer position for deceleration, the elevator 1 is gradually decelerated to make the slide movement speed of the elevator 1 slide. Decelerate to the set low speed, and then stop the slide movement when sliding to the outward position.
Then, after the slide moving speed is decelerated to the slide set low speed, the elevator 1 starts to move downward toward the lower position, and the descending moving speed is gradually increased to the set descending speed. When the elevator 1 that moves downward toward the lowered position moves downward to the lower position for deceleration, it gradually decelerates and when the elevator 1 moves downward to the lowered position, the downward movement stops and the elevator 1 moves to the external position. Let

In addition, when the descent button 54b of the pendant operation tool 54 is pushed in the state of being located at the external position, the elevating platform 1 starts to move upward toward the ascending position, and the ascending movement speed is set to the set ascending speed. When the elevator 1 is gradually increased and moved upward toward the ascending position at the set ascending speed, when the ascending / descending platform 1 is moved up to the upper position for deceleration, the elevator 1 is gradually decelerated and the ascending movement speed of the elevator 1 is decelerated to the lower setting speed Then, when the ascending movement is made to the ascending position, the ascending movement is stopped.
Then, after decelerating the ascending movement speed to the ascending set low speed, the sliding base 1 is started to slide toward the inward position, and the sliding moving speed is gradually increased to the setting slide speed, and the setting slide speed is set. When the elevator 1 that slides toward the inward position slides to the inward position for deceleration, when the elevator 1 is gradually decelerated and the elevator 1 slides to the inward position, the slide movement stops and the elevator 1 is moved. Move to an external position.
