Description

  The present invention relates to a vehicular sliding door device, and more particularly to a vehicular door device that closes a door opening provided on a side surface of a vehicle body such as a truck or a van type car.

  In a van-type vehicle or the like whose rear body is used exclusively for the cargo compartment, a door opening is provided on the side of the vehicle body forming the cargo compartment to facilitate loading and unloading operations. Some have their openings opened and closed with sliding doors. (For example, Patent Document 1)

  Moreover, there is a structure as shown in, for example, FIGS. In the vehicle body structure shown in FIGS. 7 to 11, a door opening 2 is provided on the side surface 1 of the vehicle body on which a luggage compartment is formed, and the door opening 2 can be opened and closed by a slide door 3.

  The slide door 3 includes a linear upper rail 4a attached along the upper opening edge of the door opening 2 and a linear lower rail 4b attached parallel to the upper rail 4a along the lower opening edge, respectively. It is mounted via arm-shaped cams 5a, 5b, 5c and 5d, and can be moved in the front-rear direction along the side of the vehicle body by the guides of both rails 4a and 4b.

  The upper rail 4a and the lower rail 4b are formed in a U-shaped cross section. Cams 5 a and 5 b are movably attached to the upper rail 4 a via rollers 9, and cams 5 c and 5 d are movably engaged to the lower rail 4 b via rollers 9.

  Further, locking bars 6a and 6b are rotatably attached to the outer surface of the slide door 3 in a state of being positioned by the brackets 7, 7. Handles 8 are attached to the locking bars 6a and 6b so that an operator can rotate the locking bars 6a and 6b. The upper and lower ends of the locking bars 6a and 6b protrude above and below the upper and lower ends of the slide door 3, respectively, and the cam 5a is provided at each end of the locking bars 6a and 6b protruding from the upper and lower ends. The other end of -5d is fixed, and the cams 5a-5d rotate integrally with the locking bars 6a, 6b. Note that the upper and lower ends of the locking bars 6a and 6b are bent and eccentric in the middle. Accordingly, when the locking bars 6a and 6b grasp and rotate the handle 8, the upper and lower ends of the locking bars 6a and 6b rotate while drawing an arc.

  Further, locking means 10 is provided on the outer surface of the slide door 3 corresponding to the handles 8 and 8 of the locking bars 6a and 6b. The locking means 10 is configured such that when the handles 8 and 8 are rotated together with the locking bars 6 a and 6 b and the handles 8 and 8 are in a lying state that is substantially parallel to the outer surface of the slide door 3, By being arranged on the front surface of 8, 8, the handles 8, 8 are restrained in a lying state, and the locking bars 6a, 6b can be blocked from rotating.

  In the structure configured as described above, when the handles 8 and 8 are in the lying state, the cams 5a to 5d are also laid down with respect to the upper rail 4a and the lower rail 4b. The slide door 3 is disposed at a storage position (see FIGS. 8 and 9) in which the outer surface of the slide door 3 is substantially flush with the vehicle body side surface 1, and the door opening 2 is closed by the slide door 3. ing.

  On the contrary, when the handles 8 and 8 are rotated to a state where they are raised approximately 90 degrees with respect to the outer surface of the slide door 3, the cam action of the cams 5a to 5d and the rails 4a and 4b and the locking bars 6a and 6b The slide door 3 is lifted in conjunction with the rotation of the handles 8 and 8 and is translated to an open preliminary position (see FIGS. 10 and 11) that is farther outward than the vehicle body side surface 1 from the storage position. Further, when the slide door 3 is pushed from the preliminary opening position toward the door open position, the slide door 3 is slid to the door open position by the engagement of the rails 4a and 4b and the cams 5a to 5d via the rollers 9. Can be moved. Thereby, the door opening part 2 will be in a full open state.

When the door opening 2 is closed, the slide door 3 is slid back from the door open position to the open preliminary position, and the handle 8 is rotated toward the lying down position at the open preliminary position. The rotation of the handle 8 rotates the locking bars 6a and 6b together with the cams 5a to 5d. By this rotation, the slide door 3 is moved from the open preliminary position to the storage position by the cam action of the cams 5a to 5d and the rails 4a and 4b and the locking bars 6a and 6b, and the door opening 2 is fully closed. Further, after the fully closed state, the handle 8 is restrained by the lock means 10. As a result, the fully closed operation is completed.

  However, in the conventional structure described above, when the handles 8 and 8 are rotated back in the lying down direction while the slide door 3 is being moved from the open preliminary position toward the door open position, the slide door 3 is moved to the vehicle body. There was a problem that a phenomenon such as rubbing the side surface 1 occurred. Therefore, the operator who opens and closes the slide door 3 needs to perform the opening and closing operation with the handles 8 and 8 being kept close to 90 degrees. However, in order to open and close the handlebars 8 and 8 while maintaining their postures close to 90 degrees, a force for maintaining the angles of the handles 8 and 8 is required in addition to the sliding force of the sliding door 3, and extra operating force is required. Was necessary.

  Therefore, when the sliding door moves between the open preliminary position and the door opening position, even when the operator does not particularly keep the angle of the handle that rotates together with the locking bar during opening / closing operation of the sliding door. In addition, it is easy to operate by automatically holding the handle at a predetermined angular position, and there arises a technical problem to be solved in order not to require extra force when opening and closing the slide, The present invention aims to solve this problem.

  The present invention has been proposed in order to achieve the above object, and a rail attached along a lower opening edge of a door opening provided on a side surface of a vehicle body, and an outer surface substantially flush with the side surface of the vehicle body. A sliding door disposed at a storage position that closes the door opening, a locking bar that is provided with a handle and is rotatably attached to the sliding door, and a locking member that locks the locking bar so that the rotation of the locking bar can be released. A door lock means, and an arm-shaped cam having one end fixed to the locking bar and the other end slidably and rotatably engaged with the rail via a roller, and the locking bar is rotated. And the other end of the cam rotates with the roller as a fulcrum, and the sliding door is opened farther outward than the side of the vehicle body from the retracted position. The slide door is moved parallel to the preliminary position, and the sliding door is moved along the side surface of the vehicle body from the open preliminary position toward the door open position where the door opening is fully opened by the engagement guide of the roller and the rail. In the vehicle sliding door device that can be made, a portion that extends from the other end portion of the cam at a substantially right angle is provided at the other end portion of the cam, and the extension portion is aligned with the roller. The auxiliary roller that is attached to the locking bar and rotates together with the cam when the sliding door moves between the retracted position and the open preliminary position by the rotation of the locking bar. Provided is a vehicle slide door device in which a guide rail portion for guiding the movement of the vehicle is provided continuously with the rail.

  According to this configuration, when the locking bar is rotated via the handle in a state where the sliding door is disposed at the retracted position, the sliding door is lifted by the cam action of the cam and the rail via the locking bar and the roller, It is translated from the retracted position to the open preliminary position that is farther outward than the side surface 1 of the vehicle body. Further, when the auxiliary roller is moved to the open preliminary position, the auxiliary roller corresponds to the rail, and when the slide door is further moved toward the open position, the auxiliary roller is disposed in the rail and moves together with the slide door. That is, when the sliding door moves between the open preliminary position and the open position, the two rollers of the roller attached to the cam and the auxiliary roller attached to the extension portion move simultaneously in the rail. Therefore, even if the operator does not hold down the handle, the cam does not rotate freely and the slide door does not approach the outer surface of the side part of the vehicle body. Therefore, the operator only needs to apply power to the sliding operation in the front-rear direction of the sliding door.

  According to the first aspect of the present invention, when the sliding door moves between the open preliminary position and the open position, the two rollers of the roller attached to the cam and the auxiliary roller attached to the extension portion are rails. Because the cam moves side by side, the cam does not rotate freely even if the operator does not hold down the handle, so the cam rotates without permission and the sliding door approaches the outer surface of the side of the vehicle body Disappears. As a result, the operator only has to apply power to the sliding operation in the front-rear direction of the sliding door, which facilitates the operation and eliminates the need for extra force during the sliding opening / closing operation, improving workability. There is an advantage of doing. Moreover, since it can be realized simply by providing the extension portion, the auxiliary roller, and the guide portion on the cam having the conventional structure, there is an advantage that the change from the conventional structure to the structure of the present invention can be easily performed.

  Provided at the other end of the cam that rotates integrally with the locking bar by the handle operation is a portion extending from the other end so as to be bent at a substantially right angle, and the auxiliary roller is aligned with the roller on the cam. Installed in line. When the sliding door moves between the open preliminary position and the open position, the two rollers of the roller attached to the cam and the auxiliary roller attached to the extending portion are simultaneously aligned in the rail. By moving, the cam and the locking bar do not rotate freely even if the operator is not holding the handle, so that the sliding door does not approach the outer surface of the side part of the vehicle body.

  1 to 6 show an embodiment of a sliding door device according to the present invention. The difference between the configuration of the sliding door device in the present invention and the configuration of the conventional sliding door device shown in FIGS. 7 to 11 is that the sliding door device of the present invention is different from the lower rail of the conventional sliding door device. The guide rail part is additionally provided, and the cam 5c that rotates integrally with the locking bar 6a is provided with an extension part and an auxiliary roller, and the other structures adopt the same structure. . Therefore, in the following description, the same reference numerals are given to members corresponding to the members of the conventional sliding door device, and redundant description is omitted, and only different portions will be described.

  1 to 6, the cam 5c, which has one end fixed to the locking bar 6a and the roller 9 attached to the other end, is extended from the other end by bending at a substantially right angle along the horizontal plane. The part 13 is provided integrally. The extending portion 13 is provided with a rotatable auxiliary roller 11 aligned with the roller 9 in a straight line.

  As is clear from FIGS. 5 and 6, the lower rail 4 b is integrated with the cam 5 c when the locking bar 6 a is rotated via the handle 8 in a state where the slide door 3 is disposed at the open preliminary position. A guide rail portion 12 is formed continuously from one end side of the lower rail 4b. The guide rail portion 12 has a shape corresponding to an arc-shaped trajectory drawn by the auxiliary roller 11 that rotates in a straight line. The guide rail portion 12 is formed in a substantially U-shaped cross section, and receives the auxiliary roller 11 in the U-shaped rail groove, and when the guide rail portion 12 rotates, the auxiliary roller 11 The inner wall abuts on both sides of the roller and serves to guide the turning movement of the auxiliary roller 11.

  Next, the operation of the slide door device configured as described above will be described. Also, in the sliding door device of the present invention, the operation of the portions other than the locking bar 6a and the cam 5c is the same as the operation of the conventional sliding door device, so the operation in the portions of the locking bar 6a and the cam 5c. Only will be described.

  First, when the handle 8 is in a state of being laid down substantially parallel to the outer surface of the slide door 2, the cam 5c is also laid down with respect to the lower rail 4b. The door opening 2 is closed at a storage position (see FIGS. 1, 2 and 5) that is substantially in the same plane. The roller 9 is disposed in the rail groove of the lower rail 4b, and the auxiliary roller 11 is disposed in the rail groove of the guide rail portion 12.

  When the handle 8 is rotated to a state where it is raised approximately 90 degrees with respect to the outer surface of the slide door 3 in a state where the slide door 3 is disposed at the retracted position, the cam of the cam 5c, the lower rail 4b, and the locking bar 6a. By the action, the slide door 3 is lifted in conjunction with the rotation of the handle 8 and is translated in parallel to an open preliminary position (see FIGS. 3 and 4) that is farther outward than the side surface 1 of the vehicle body from the storage position. Further, when the cam 5c rotates, the auxiliary roller 11 is also pivoted through the rail groove of the guide rail portion 12, and in the state where the slide door 3 is disposed at the open preliminary position, the auxiliary roller 11 is positioned in the lower rail 4b, It is aligned with the roller 9 in the lower rail 4b.

  Next, when the slide door 3 is pushed from the open preliminary position toward the door open position, the roller 9 and the auxiliary roller 11 move in a state in which the two in the lower rail 4b are aligned, and this movement causes the slide door 3 to move to the door. It can be slid to the open position. When the door opening 2 is closed, the slide door 3 is slid from the door open position to the open preliminary position and returned. Even during this returning operation, the roller 9 and the auxiliary roller 11 move to the door opening position in a state where two rollers 9 and the auxiliary roller 11 are arranged side by side. Therefore, in the movement from the open preliminary position to the door open position and the movement from the door open position to the open preliminary position, the roller 9 attached to the cam 5c and the auxiliary roller 11 attached to the extending portion 13 are two. Since the two rollers move in a straight line in the rail groove of the lower rail 4b, the cam 5c does not rotate arbitrarily even if the operator does not hold the handle. As a result, the cam 5c does not rotate freely during the slide operation, and the slide door 3 does not approach the side of the vehicle body, so that the operator only has to apply power to the open / close slide operation of the slide door.

  When the slide door 3 returns to the open preliminary position, the handle 8 is rotated toward the lying down position at the open preliminary position. The rotation of the handle 8 causes the locking bar 6a to rotate with the cam 5c, and the cam action of the cam 5c, the lower rail 4b and the locking bar 6a causes the slide door 3 to move to the retracted position in conjunction with the rotation of the handle 8. The opening 2 is fully closed. At the same time, the auxiliary roller 11 moves in the rail groove of the guide rail portion 12 when the cam 5c rotates. Further, after the fully closed state, the handle 8 is restrained by the lock means 10. Thereby, the fully closed operation is completed.

  Therefore, according to the slide door device in the embodiment of the present invention configured as described above, when the slide door 3 moves between the open preliminary position and the open position, the roller attached to the cam 5c. Since the two rollers 9 and the auxiliary roller 11 attached to the extending portion 13 move in a straight line in the lower rail 4b, the cam 5c rotates freely even if the operator does not hold the handle 8. This prevents the sliding door 3 from approaching the outer surface of the vehicle body side. Thus, the operator only has to apply power to the opening / closing operation of the slide door 3, so that the operation is facilitated, and an extra force is not required at the time of opening / closing the slide, thereby improving workability. .

  In addition, since the cam 5c having the conventional structure can be realized simply by providing the extending portion 13, the auxiliary roller 11, and the guide rail portion 12, the change from the conventional structure to the structure of the present invention can be easily performed. There are advantages.
