  The present invention is provided in a mounting portion that mounts and lowers a mounting body, and receives and prevents the mounting body from moving outward from the mounting portion, and the mounting posture. A receiving body that is rotatable to an allowable posture that allows the mounting body to move outward from the mounting portion, and a rotating body that rotates together with the receiving body, when the receiving body is in the blocking posture. A locking device that is detachable and elastically biased toward the engagement side, and a forward rotation operation and a backward rotation operation around the coaxial core with the rotating body by an actuator, and a diameter from the radially inner side. In the initial rotation of the forward rotation, the cam surface formed toward the outer side in the direction is operated to press to the detaching side to release the lock tool from the rotating body by the initial rotation of the forward rotation. Rotating body linked to the rotating body in a state allowing relative rotation It relates catching member operation structure of a vehicle lifting device comprising a rolling driving rotator for operation.

  The receiving body structure of such a vehicle lifting device includes a wheelchair that is placed on the mounting portion while the mounting portion is lifted by engaging the lock member with the rotating body and holding the receiving body in a blocking posture. When the mounting body is moved from the mounting table to the outside ground, etc., the locking device is moved from the rotating body. After the detachment, the receiving body is switched to an allowable posture to allow the mounted body to move outward. Then, in order to switch the receiving body held in the blocking posture to the allowable posture, the driving rotary body is operated to rotate forward by the actuator, and the cam surface formed on the driving rotary body by the initial rotation of the driving rotary body is used.

JP 2003-341409 A

  In the above conventional configuration, since the cam surface is formed in a flat shape, when the locking device is pressed to the detachment side on the radially inner cam surface, the drive is started from the locked state as shown in FIG. By rotating the rotating body, the lock tool and the cam surface come into contact with each other, and by further rotating, the lock by the lock tool is released through the middle. However, since the distance from the contact point on the cam surface to the center of rotation and the center of rotation is short and the amount of movement of the lock tool per unit rotation of the drive rotator is small, it can be locked by rotating the drive rotator with a small torque. Although the tool can be pressed to the detachment side, when the lock tool is pressed to the detachment side on the radially outer cam surface, from the location where the cam surface contacts the lock tool to the center of rotation. Since the distance is long and the amount of movement of the lock tool per unit rotation of the drive rotator is large, it is necessary to rotate the drive rotator with a large torque in order to push the lock tool to the release side. A large torque is required to rotate the drive rotator so as to press the squeeze to the detachment side, and it is difficult to detach the lock tool from the rotator.

  The present invention has been made in view of the above circumstances, and its purpose is to reduce the torque of the drive rotating body necessary for the pressing operation to release the lock tool from the rotary body to the release side, and It is in the point which provides the receiving body operation structure of the raising / lowering device for vehicles which is easy to remove | separate from a rotary body.

A locking device provided in a state in which the receiving body is detachable and elastically biased toward the engagement side when the receiving body is in the blocking posture, and a forward rotation operation and a backward rotation operation around the coaxial core with the rotating body by an actuator A pressing operation on a detaching side for releasing the locking device from the rotating body by an initial rotation of the forward rotation on a cam surface formed from a radially inward side toward a radially outward side; and In the initial rotation of the forward rotation, relative rotation is allowed. A receiving member operating structure of a vehicle lifting device comprising a driving rotating member for coordinated the rotating body rotating operation to the rotating body in that state,
The first characteristic configuration is characterized in that the cam surface of the drive rotating body is formed in a shape bulging in the forward rotation direction.

  That is, since the cam surface is formed in a bulging shape, as shown in FIG. 19, when the locking member is pressed to the release side on the radially inner cam surface, the bulging cam surface is As a result, the amount of movement of the locking device per unit rotation of the drive rotator is increased, and when the locking device is pressed to the release side on the radially outer cam surface, the bulging cam surface must be lowered. This reduces the amount of movement of the locking tool per unit rotation of the drive rotator, and the torque required for pressing the locking tool to the release side on the radially inner cam surface and the radially outer cam It is possible to reduce the torque of the drive rotator necessary for the pressing operation to release the lock tool from the rotating body to the release side by averaging the torque required when the lock tool is pressed to the release side on the surface. Can rotate the lock Leading to possible to provide a receiving member operating structure for easy vehicle lifting device is detached from.

  The second characteristic configuration is characterized in that the cam surface of the drive rotating body is formed in a curved shape over the entire range from the radially inner side to the radially outer side.

  That is, since the entire range of the cam surface is formed into a curved surface, the pressing operation to the detachment side of the lock device by the cam surface can be performed smoothly, and the lock device is smoothly detached from the rotating body. be able to.

  Next, the swing operation structure of the rear receiving body 28 will be described. As shown in FIGS. 8 and 9, the rear receiving body 28 has its left and right end portions around the fixed horizontal axis 30 along the horizontal width direction via the rear receiving body bracket 28a, that is, the axis L1 of the fixed horizontal axis 30. It is pivotally attached to the rear end edge of the lifting platform 1 so that it can swing around.

  In the support column 52, a rotating body 31 that rotates integrally with the rear receiving body 28 is provided in a state in which the rear receiving body 28 is detachable and elastically biased toward the engaging side when in the blocking posture. A forward rotation operation and a backward rotation operation are performed around a coaxial core with the rotating body 31 by a lock plate (corresponding to a locking device) 38 and the rear receiving body motor 36, and from the radially inner side to the radially outer side. The lock surface 38 is pressed toward the detaching side for releasing the lock plate 38 from the cam plate 31 by the initial rotation of the forward rotation on the cam surface 41a formed toward the front, and the relative rotation is allowed in the initial rotation of the forward rotation. A drive rotator 32 for rotating the cam plate, which is linked to the lock plate 38 in the state, is provided.

As shown in FIG. 9, the rotating body 31 that rotates integrally with the rear receiving body 28 around the axis L <b> 1 is connected to the right side of the rear receiving body bracket 28 a, and on the right side of the rotating body 31. Is provided with the drive rotator 32 that rotates about the axis L1.

The cam plate 41 located on the left side of the sprocket 43 in the mounted state is attached to the rotator 31. An engaging groove 41b into which the connecting pin 33 provided in is engaged is formed. A chain 35 is stretched over the sprocket 43 across the motor-side sprocket 34 that is rotationally driven by the rear receiving body electric motor 36.
Accordingly, when the rear receiving body electric motor 36 is operated to rotate the sprocket 43, that is, the drive rotating body 32, the rotation is transmitted to the rotating body 31 via the connecting pin 33 and the rotating body 31 rotates. The receiving body 28 is configured to swing. Incidentally, when the drive rotating body 32 rotates in the counterclockwise direction when viewed from the right side, the rear receiving body 28 swings to the permissible posture side, and the drive rotor 32 rotates in the clockwise direction when viewed from the right side. When rotated, the rear receiving body 28 swings to the blocking posture side.

Accordingly, by operating the manual lever 42, the lock plate 38 is swung against the urging force of the spring 40 so that the holding by the holding mechanism 44 is released and the locking projection 38a is detached from the locking notch 31a. By doing so, the engagement of the locking projection 38a with the locking notch 31a is released, and the lock can be released. In this unlocked state, as shown in FIGS. 11 and 12, the rear receiving body 28 can be manually switched to the allowable posture B2 or the retracted posture B3.

The cam plate 41 of the drive rotating body 32 is formed with a cam surface 41a with which the locking projection 38a contacts when the rear receiving body 28 is in the blocking posture B1. That is, the locking protrusion 38a is formed wide in the direction of the axis L1, and is configured to be able to engage with the locking notch 38a and to contact the cam surface 41a. As shown in FIG. 15 (a), in the locked state, the cam plate 41 and the locking projection 38a are separated from each other, and as the cam plate 41 rotates, as shown in FIG. The cam surface 41a of the plate 41 and the locking projection 38a are in contact with each other.
The cam surface 41a is formed from the radially inner side to the radially outer side of the cam plate 41. When the cam plate 41 rotates, the locking projection 38a is moved to the cam plate by the cam surface 41a. As shown in FIGS. 15 (c) and 15 (d), the locking projection 38a is moved from the radially inward side to the radially outward side toward the cam surface 41a by pressing the 41 toward the radially outward side. The locking projection 38a is separated from the locking notch 31a by moving along the radial direction.

  The cam surface 41a is formed in a curved shape that bulges in the forward rotation direction over the entire range from the radially inner side to the radially outer side, and the locking protrusion 38a is radially inward. By moving along the cam surface 41a having a shape bulging outward from the radial direction, the amount of pressing operation per unit angle is larger than that formed flat on the radially inner side, and The pressing operation amount per unit angle is set to be smaller on the radially outer side than that formed flat, and the torque on the radially outer side, which required a large torque, can be suppressed. Thus, the minimum torque required to release the lock can be reduced.

  The engaging groove 41b formed in the cam plate 41 is formed in an arc shape around the axis L1, and the connecting pin 33 provided in the rotating body 32 and engaged in the engaging groove 41b is connected in an arc shape. It is configured to be movable along the insertion groove 41b. Accordingly, the drive rotator 31 provided with the cam plate is rotated relative to the rotating body 32 by a set angle in which the engaging groove 41b is formed, and the drive rotator 31 is rotated beyond the set angle to thereby drive the rotator. 31 and the rotation body 32 are comprised so that it may rotate integrally.

  Therefore, as shown in FIG. 13, in the state in which the rear receiving body 28 is locked to the blocking posture B1 by the locking tool, the set angle that can be relatively rotated with respect to the rotating body by driving the drive rotating body 31. During the rotation, the lock is released by the cam action of the cam surface, and the rear receiving body is switched to an allowable posture by rotating the rotating body that has been unlocked by rotating more than a set angle.
