  In the sliding door device in which the lower roller provided at the lower portion of the door body is movably mounted on the lower rail member, a lifting force from the lower rail member is generated on the lower roller due to an external force acting on the door body. Then, since there is a possibility that the lower roller may come off from the lower rail member, it is required to take measures against this.

  An object of the present invention is to provide a sliding door device that can eliminate the possibility that the lower roller will come off from the lower rail member even if a lifting force is generated on the lower roller from the lower rail member.

  The sliding door device according to the present invention is provided with a lower rail member, and a lower roller which is provided at the lower portion so as to be able to roll on the lower rail member, and is guided by the lower rail member to be movable. And the lower rail member is provided with a locking portion protruding in the thickness direction of the door body, and the lower part of the door body has the above-mentioned On the lower side of the locking portion, a lifting prevention portion is provided which is opposed to the locking portion in the vertical direction and is locked to the locking portion when the lower roller is lifted from the lower rail member. It is what.

  As described above, in the sliding door device according to the present invention, the lower rail member is provided with the locking portion protruding in the thickness direction of the door body, and the lower portion of the door body is below the locking portion. In addition, since the anti-lifting portion is provided so as to be opposed to the engaging portion in the vertical direction and engage with the engaging portion when the lower roller is lifted from the lower rail member, the lower roller generates a lifting force from the lower rail member. In this case, the lifting prevention portion is locked to the locking portion, so that the lower roller does not lift significantly, and the possibility that the lower roller is removed from the lower rail member can be eliminated.

  Providing such a lifting prevention part at the lower part of the door body, for example, arranges a lifting prevention member at the lower part of the door body, and forms a part formed by protruding in the thickness direction of the door body on this lifting prevention member However, this can be realized by using this portion as a floating prevention portion.

  Further, when the anti-lifting member is arranged in the lower part of the door body as described above, a portion formed in the thickness direction of the door body is formed on the anti-lifting member, and this portion is used as the anti-lifting portion. The length dimension in the moving direction of the door body with respect to the lifting prevention member may be the same as or slightly shorter than the left and right dimensions of the door body in the moving direction, or the left and right dimensions of the door body. It is good also as a dimension short enough compared with.

  When the length dimension in the opening / closing movement direction of the door body is the same as the left / right dimension of the door body or a little shorter than the left / right dimension as in the former case, By forming it over the entire length, it is possible to provide the lifting prevention portion over the entire length in the left-right direction or substantially the entire length of the door body.

  The length of the door body in the opening / closing movement direction of the lifting prevention member is the same as or slightly shorter than the left / right dimension of the door body, and the door body opens / closes the opening. In order to do so, it is guided by the lower rail member and is movable, and the length dimension of the lifting prevention member is larger than the left and right dimensions of the opening when the door body reaches the fully open position, When the lifting prevention member is inserted into the lower part of the door body from the end surface on the closing side of the door body, the length of the lifting prevention member is smaller than the left and right dimensions of the opening. It is preferable to form the plurality of divided members.

  According to this, when the door body reaches the fully open position, the work for inserting the respective divided members forming the lifting prevention member in series from the end surface on the closing side of the door body to the lower part of the door body By inserting these divided members, the length dimension of the door body in the opening / closing movement direction is larger than the left-right dimension of the opening, and is the same as the left-right dimension of the door body or from the left-right dimension. In addition, a lifting prevention member having a slightly shorter dimension can be disposed at the lower portion of the door body.

  In the same manner as described above, the length dimension in the opening / closing movement direction of the door body with respect to the lifting prevention member is the same as or slightly shorter than the left-right dimension of the door body, In order to open and close the opening, it is guided by the lower rail member and is movable, and a building housing is provided at a position on the opening side of the door body when the fully closed position is reached, to prevent lifting The length dimension of the member is larger than the distance between the opening side end surface of the door body and the building frame when the fully closed position is reached, and the lifting prevention member is separated from the opening side end surface of the door body. When it is to be inserted into the lower part of the door body, it is preferable that the lifting prevention member is formed by a plurality of divided members each having a length dimension smaller than the distance.

  According to this, when the door body has reached the fully closed position, each divided member forming the lifting prevention member is inserted in series from the open end face of the door body into the lower part of the door body. With the insertion of these divided members, the length dimension of the door body in the opening / closing movement direction is greater than the distance and is the same as the left-right dimension of the door body or larger than the left-right dimension. A lifting prevention member having a slightly shorter dimension can be arranged at the lower part of the door body.

  In the present invention described above, the locking portion of the lower rail member may be provided over the entire length of the lower rail member, or, for example, provided at a plurality of positions at intervals in the entire length of the lower rail member. May be.

  When the locking portion is provided over the entire length of the lower rail member, the lifting force from the lower rail member is exerted on the lower roller regardless of the position of the door body that is guided and moved by the lower rail member. When this occurs, it is possible to prevent the lower roller from floating significantly, and to eliminate the possibility of the lower roller coming off the lower rail member.

  When the locking portion is provided over the entire length of the lower rail member in this way, the lower rail member is extended to one side in the thickness direction of the door body, and the base portion. A standing part that stands vertically from the base end of the vertical part, and a folded part that is folded downward from the upper end of the standing part and reaches the middle of the standing part, and is overlapped in the thickness direction of the standing part and the door body, A portion projecting from the lower end portion of the folded portion to the other side in the thickness direction of the door body may be included, and this portion may be used as the locking portion. And when making a lower rail member into such a thing, the connection part of a standing part and a folding | returning part turns into a guide part in which the said lower roller is mounted so that rolling is possible.

  Such a lower rail member can be manufactured at a low cost by bending a thick plate metal.

  In addition, when the lower rail member is as described above, the lower rail member is fixed to the upper surface of the hulling member, and the upper surface of the hulling member has the upright portion and the base portion as described above. It is preferable to place a supporting member that is coupled on the opposite side of the door body in the thickness direction and below the locking portion.

The door closing device 55 is closed and moved by the pulling force of the long coil spring of the door closing device 55 and the pulling force of the wire 51 of the automatic closing device 50. When the locking member 55B reaches near the movement limit position on the closing side, in other words, when the door body 1 approaches the fully closed position, the movement speed of the locking member 55B decreases due to the action of the damper. The door body 1 reaches the fully closed position while decreasing the closing movement speed.

  Further, when the door body 1 that has reached the fully closed position is opened and moved by the hand that grips the grip portion 40, the door body 1 and the locking member 55B are moved by the action of a check valve provided in the damper. When the locking member 55B reaches the above-mentioned movement limit position on the opening side while accumulating a pulling force on the long coil spring, the movement of the locking member 55B is guided. Due to the action of the guide groove formed in the above-mentioned guide member, the locking member 55B swings in the opposite direction to the above-described direction. Therefore, the operating member 56 locked to the locking member 55B The door 1 is separated from the locking member 55B, and thus the door 1 is separated from the door closing device 55 and reaches an open position such as a fully open position.
