Means for Solving the Problems In order to solve the above-mentioned problems, in the present invention, a vertical roller extending in the vertical direction is arranged along an edge of the door pocket of the vehicle door inside the vehicle, and the door moves in the opening direction. In this case, the vertical roller is driven to rotate in the direction opposite to the direction in which the door moves. According to this configuration, there is a vertical roller at the edge of the door pocket of the vehicle door, and when the vertical roller rotates in the opening direction of the door, the vertical roller rotates in the direction opposite to the direction of movement of the door. The hand is pushed back out of the door pocket, even near the edge of the. Therefore, the problem of finger stuffing, in which fingers and wrists are pinched in the door pocket, is eliminated. More specifically, the device of the present invention comprises a longitudinal roller extending longitudinally along an edge of the interior of the door pocket of the vehicle inside the vehicle, contacting the longitudinal roller and being transverse to the direction of door movement. A rotation transmitting roller disposed so as to be movable in the direction, the rotation transmitting roller is separated from the door when the door moves in the closing direction, and the rotation transmitting roller is brought into contact with the door when the door moves in the opening direction. And a rotation transmitting roller moving mechanism for moving. When the door moves in the opening direction, the rotation transmitting roller comes into contact with the door and is driven to rotate by the door, whereby the vertical roller is rotationally driven in the direction opposite to the moving direction of the door via the rotation transmitting roller. Is done.

Preferred embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, a vehicle body 1 of a train includes a vehicle body panel 2 having a door opening 2a, and a door pocket 4 for a sliding door type door 5 is formed between the vehicle body panel 2 and the vehicle body inner plate 3. In the example shown in the figure, the present invention is applied to a double door that opens in both left and right directions, and a pair of doors 5 is drawn into a door pocket 4 formed on both sides of a door opening 2a. Along the edges of the door pockets 4 on the left and right, a vertical roller 6 for preventing finger jamming is arranged so as to close a gap between the inner surface of the door 5 and the edge of the inner plate 3. The vertical roller 6 for preventing finger jamming is disposed so as to extend over the entire height of the door opening 2a, and is rotatably supported by the vehicle body structure at the upper end and the lower end. The rotation transmitting roller 7 is always in contact with the finger jam prevention vertical roller 6.
Are arranged in each door pocket 4.

FIG. 2 shows details of the support structure and operation of the vertical roller 6 for preventing finger jamming and the roller 7 for transmitting rotation. The rotation transmitting roller 7 is always kept in contact with the vertical roller 6 so as to transmit a rotational driving force to the vertical roller 6 for preventing finger jamming. The rotation transmitting roller 7 does not need to be long enough to extend over the entire length of the finger jam prevention vertical roller 6, and may be arranged at a position corresponding to the upper end or lower end of the vertical roller 6 or an intermediate portion thereof. . Roller 7 is
It can be supported on the vehicle body inner plate 3 or a vehicle body structural member provided in the vicinity thereof by using a bracket (not shown) or the like.
The rotation transmitting roller 7 is guided by the guide groove 8 so that the rotation shaft 7 a can be displaced in a direction substantially perpendicular to the surface of the door 5, and is urged toward the door 5 by the urging spring 9. Is done.

A sleeve 10 is fitted on the rotation shaft 7a of the rotation transmitting roller 7. This sleeve 10 has a pair of legs 1
1a and 11b are fixed at an angle to each other.
2a and 12b are attached. The length of the leg 11a is determined such that the roller 12a pushes the rotation transmitting roller 7 away from contact with the door 5 when the leg 11a is positioned in a direction substantially perpendicular to the door 5. In operation, FIG. 2 (a) shows a state in which the door is completely opened. A roller 7 for rotation transmission is provided on the inner surface on the tip side of the door 5.
At the position corresponding to the roller 12a supported by the
When the door 5 is open, the rollers 12a
Is in a state of being accommodated in the recess 13. The rotation transmitting roller 7 is kept in contact with the door 5 by the action of the spring 9. When the door 5 is moved in the direction of the arrow in FIG. 3A to close the door 5, the sleeve 10 and the legs 11a and 11b rotate clockwise in the figure because the roller 12a rides on the shoulder of the concave portion 13. . Therefore, the rotation transmitting roller 7 is pushed and separated by the action of the legs 11a and the roller 12a as shown in FIG. 2 (b). The rotation of the leg 11a in the clockwise direction is performed by the roller 1 supported by the leg 11b.
1b stops when it comes into contact with the vertical roller 6 for preventing finger jamming. In this position, the leg 11a is
Is slightly overclockwise from the position orthogonal to the plane. Since the leg 11a is urged in the direction of the door 5 by the spring 9, the leg 11a
There is no danger that a will be returned counterclockwise. Therefore, while the door 5 is moving in the closing direction, the rotation transmitting roller 7 is
The vertical roller 6 for preventing finger stuffing does not rotate because it is maintained at a position distant from the camera and does not rotate.

FIG. 2C shows a state in which the door 5 is in the closed position. A recess 14 is formed near the rear end of the door 5 at a position corresponding to the roller 12a. Therefore, the rotation transmitting roller 7
Is pressed against the door 5 by the urging force of the spring 9.
When the door 5 is moved in the opening direction from this state, the legs 11a
The upper roller 12a rides on the inner surface of the door 5, and the legs 11a,
11b rotates counterclockwise to the state shown in FIG. 2 (d). In this state, the rotation transmitting roller 7 is not pushed away from the door 5 by the leg 11a, but is pressed against the door 5 by the action of the spring 9. Accordingly, the rotation transmitting roller 7 is driven by the door 5 moving in the direction indicated by the arrow A in FIG. Since the roller 7 is in contact with the vertical roller 6 for preventing finger stuffing in a driving force transmitting relationship, the rotation of the roller 7 is transmitted to the vertical roller 6, and the vertical roller 6 rotates in the direction indicated by the arrow C. This rotation direction is opposite to the direction of movement of the door 5, so that even if the passenger carelessly places his or her hand on the edge of the door pocket 4, the hand is pushed back by the vertical roller 6, and the The wrist is not drawn into the door pocket 4.

[0009]

As described above, according to the present invention,
A vertical roller extending in the vertical direction along the edge of the door pocket of the vehicle inside the vehicle is arranged so that when the door moves in the opening direction, the vertical roller is driven to rotate in the direction opposite to the moving direction of the door. Therefore, even when the passenger carelessly places his hand on the edge of the door pocket, it is possible to prevent the finger or wrist of the hand from being pulled into the door pocket.
