  In the door wheel as described above, the reaction force due to the load of the shoji acts on the engagement position between the roller and the rail arranged on the rail, and the load of the shoji acts on the engagement position between the guide projection and the inclined end surface. To do. When adjusting the height of the roller, the inner frame moves in the direction in which the inner frame is found. For this reason, even if the position of the roller in the inner frame remains unchanged, the position of engagement with the guide protrusion changes, so that the balance of the external force acting on the door pulley is extremely disrupted by adjusting the height of the roller. When a large force acts on the inclined end face, there is a problem that the roller may become unstable or the inner frame or the outer frame may be deformed and the roller may be difficult to rotate.

  The present invention has been made in view of the above problems, and the object of the present invention is to provide a door wheel and a door wheel in which the balance of external force acting on the door wheel is not easily lost even if the height is adjusted by moving the roller. An object of the present invention is to provide a joinery having a shoji screen.

In order to achieve this object, the door wheel of the present invention is a door wheel provided with a roller that supports a shoji that moves along the rail while rotating on the rail of the frame body,
An inner frame having a pair of inner facing portions that are opposed to each other in the expected direction of the shoji and are supported by the rotation shaft of the roller so as to be rotatable.
An outer frame that has a pair of outer facing portions that are located on the outer sides in the prospective direction of the pair of inner facing portions and face the inner facing portion, and is fixed to the shoji,
A moving mechanism capable of moving the inner frame vertically with respect to the outer frame;
Have
An inner engagement portion that is provided in the inner facing portion and that is supported by the outer guide portion and that is supported by the inner frame while being supported by the inner frame and that is supported by the inner frame. An outer engagement portion guided by an inner guide portion provided on the inner facing portion is disposed on both sides of the rotation shaft in the finding direction;
The inner frame is positioned on the upper side of the moving range of the inner frame in the vertical direction, and the distance in the direction in which the inner engagement portion and the rotation shaft are found is the direction in which the outer engagement portion and the rotation shaft are found. After the shoji is incorporated into the frame in a state shorter than the distance in
When the inner frame is moved downward by the moving mechanism, the inner frame is moved in a direction in which the distance between the outer engagement portion and the rotation shaft is shortened.

  According to such a door cart, the weight of the shoji is supported by the rail via the roller from the inner engagement portion and the outer engagement portion. Therefore, the weight of the shoji acts downward on the inner engagement portion and the outer engagement portion, and the reaction force acts upward on the rotating shaft of the roller supported by the rail. For this reason, in order to support the shoji in a well balanced manner in the door pulley, the distance in the direction of finding the inner engaging portion and the rotating shaft should be equal to the distance in the direction of finding the outer engaging portion and the rotating shaft. desirable.

  Of the inner engagement portion and the outer engagement portion arranged on both sides of the roller rotation shaft in the direction of finding, the inner engagement portion that supports the outer frame is the same as the rotation shaft of the roller. Since it is provided in the inner frame, the distance in the direction of finding the rotation shaft and the inner engaging portion is unchanged. On the other hand, the distance between the outer engagement portion and the rotation shaft is such that the inner frame is located on the upper side of the moving range and the shoji is placed on the frame body in a state longer than the distance in the direction of finding the inner engagement portion and the rotation shaft. When the inner frame is moved downward, the inner frame is moved in a direction that shortens the distance between the outer engaging portion and the rotation shaft. After the movement, the distance in the direction in which the inner engagement portion and the rotation shaft are found and the distance in the direction in which the outer engagement portion and the rotation shaft are equal approach each other. It is possible to provide a door cart in which the balance of the external force acting on the door cart is not easily broken even if it is done.

  In this door roller, it is desirable that the inner frame is positioned at the upper end of the moving range in a state where the door frame is attached to the shoji, and the upper frame is restricted from moving upward by the outer frame.

  According to such a door wheel, when the door wheel is attached to the shoji, the outer frame restricts the movement of the inner frame upward, so that the inner frame is positioned on the upper side and rotates with the inner engagement portion. Even if the distance in the direction in which the moving shaft is located is shorter than the distance in the direction in which the outer engagement portion and the rotating shaft are located, the inner frame is prevented from moving upward by the outer frame, and thus stable. It is possible to keep the state. For this reason, even if the roller is placed on the rail without being moved downward, the shoji can be stably supported.

  In the door frame, the inner frame is configured such that the distance in the direction in which the inner engagement portion and the rotation shaft are found is equal to the distance in the direction in which the outer engagement portion and the rotation shaft are found. It is desirable to be moved.

  According to such a door pulley, the inner frame is moved so that the distance in the direction of finding the inner engaging portion and the rotation shaft is equal to the distance in the direction of finding the outer engaging portion and the turning shaft. Therefore, after the lower frame is moved downward, the external force acting on the inner engagement portion, the outer engagement portion, and the rotation shaft acts in a more balanced manner when the inner frame is positioned on the upper side. For this reason, it is possible to provide the door cart which can support the shoji in a more stable state in use.

  Moreover, it is the fitting characterized by having the said shoji provided with the said door wheel, and the said frame body in which the said shoji is integrated.

  According to such a fitting, when the shoji is incorporated into the frame, the inner frame is positioned on the upper side, and the shoji is placed on the rail, and the door roller of the shoji placed on the rail. When the inner frame provided with is moved downward, the balance of the external force acting on the door pulley is maintained and the shoji can be supported in a stable state.

The inner connecting portion 14 is also slightly inclined with respect to the vertical so that the screwing plate portion 24 and the inner connecting portion 14 of the inner frame 12 disposed inside the outer frame 30 face each other. The inner connecting portion 14 is configured to move in the direction in which the operation screw 25 enters when the operation screw 25 screwed into the screwing plate portion 24 is tightened. At this time, as shown in FIG. 5 (b), the inner frame 12 supports the edge 37a of the inclined cutout portion 37 of the outer frame 30 with the annular projection 15 and the inclined end as shown in FIG. 5 (c). The portion 13b is configured to move along the inclination of the inclined notch portion 37 and the inclined end portion 13b while supporting the edge 35a of the inclined protrusion 35. For this reason, the inclination of the inclination notch part 37 and the inclination edge part 13b and the inclination of the screwing board part 24 and the inner connection part 14 are formed so as to be orthogonal.

  The door 10 of the present embodiment is shown in the left diagram of FIG. 6 in a state where the annular protrusion 15 of the inner frame 12 can come into contact with the upper end 37b of the inclined notch 37 with the operation screw 25 loosened. As described above, the distance x1 in the direction in which the annular protrusion 15 and the rotation pin 19 are found is shorter than the distance x2 in the direction in which the inclined protrusion 35 and the rotation pin 19 are found, and the inner frame 12 is attached to the shoji. The shoji 3 is incorporated in the frame 5 so as to be positioned on the upper side of the outer frame 30.

  Thereafter, when the operation screw 25 is tightened to adjust the height of the shoji 3, the inner frame 14 is pressed and the outer frame 30 to which the screwing plate 24 is attached is raised. The height of the shoji 3 to which the frame 30 is attached rises.

And move along the inclination of the inclined end portion 13b. That is, as shown in the right diagram of FIG. 6, the distance x1 in the direction in which the annular protrusion 15 and the rotation pin 19 are found is the same as the distance x2 in the direction in which the inclined protrusion 35 and the rotation pin 19 are found. The inner frame 12 moves in the direction.

  The weight of the shoji 3 is supported by the lower rail 7 a through the roller 18 from the annular protrusion 15 and the inclined protrusion 35. For this reason, the weight of the shoji 3 acts downward on the door pulley 10 on the annular protrusion 15 and the inclined protrusion 35, and the reaction force is supported upward on the rotating pin 19 of the roller 18 supported by the lower rail 7 a. It works. For this reason, in order to support the shoji 3 in a well-balanced manner in the door pulley 10, the distance x1 in the direction in which the annular protrusion 15 and the rotation pin 19 are found and the distance in the direction in which the inclined protrusion 35 and the rotation pin 19 are found. It is desirable that x2 is equal.

  According to the door pulley 10 of the present embodiment, the annular protrusion 15 that supports the outer frame 30 among the annular protrusion 15 and the inclined protrusion 35 that are disposed on both sides of the rotation pin 19 of the roller 18 in the finding direction. Is provided on the same inner frame 12 as the rotation pin 19 of the roller 18, the distance x1 in the direction in which the rotation pin 19 and the annular protrusion 15 are found is unchanged.

  On the other hand, the distance x2 in the direction in which the inclined projection 35 and the rotation pin 19 are found is longer than the distance x1 in the direction in which the inner projection 12 is located on the upper side of the movement range and the annular projection 15 and the rotation pin 19 are found. When the shoji 3 is incorporated in the frame 5 in the state and the inner frame 12 is moved downward, the inner frame 12 is moved in a direction in which the distance x2 between the inclined protrusion 35 and the rotation pin 19 is shortened. After the door pulley 10 is moved downward, the distance x1 in the direction in which the annular protrusion 15 and the rotation pin 19 are found and the distance x2 in the direction in which the inclined protrusion 35 and the rotation pin 19 are found approach the same state. Therefore, even if the height is adjusted by the movement of the roller 18, it is possible to provide the door pulley 10 in which the balance of the external force acting on the door wheel 10 is not easily lost.

  In the state where the door pulley 10 is attached to the shoji 3, the annular protrusion 15 of the inner frame 12 is brought into contact with the upper end 37 b of the inclined notch portion 37 provided on the outer frame 30, and the inner frame 12 moves upward. Therefore, the outer frame 30 and the shoji 3 are supported in a stable state by the annular protrusion 15. Therefore, the inner frame 12 is positioned on the upper side, and the distance x1 in the direction in which the annular protrusion 15 and the rotation pin 19 are found is shorter than the distance x2 in the direction in which the inclined protrusion 35 and the rotation pin 19 are found. Even if it exists, it is possible to keep the shoji 3 in a stable state. For this reason, even if the roller 18 is not moved downward and placed on the lower rail 7a, the shoji 3 can be stably supported.

  Further, the inner frame 12 is moved so that the distance x1 in the direction in which the annular protrusion 15 and the rotation pin 19 are found is equal to the distance x2 in the direction in which the inclined protrusion 35 and the rotation pin 19 are found. After the inner frame 12 is moved downward, the external force acting on the annular protrusion 15, the inclined protrusion 35, and the rotation pin 19 acts in a better balance than when the inner frame 12 is positioned on the upper side. For this reason, it is possible to provide the door pulley 10 that can support the shoji 3 in a more stable state in use.

  Further, according to the joinery 1 having the shoji 3 provided with the door wheel 10, when the shoji 3 is assembled into the frame 5, the inner frame 12 is positioned on the upper side, and the shoji 3 is placed on the lower rail 7 a. When the inner frame 12 provided with the roller 18 of the door roller 10 included in the shoji 3 placed on the lower rail 7a is moved downward, the balance of the external force acting on the door wheel 10 is maintained and the shoji 3 is maintained. Can be supported in a stable state.

  In the said embodiment, although the joinery provided with the sliding shoji 3 was mentioned as an example and demonstrated, it is not restricted to this, What is necessary is just a joinery which has the sliding door shoji provided with the said door pulley 10. FIG.
